Background: Optimal treatment of completely displaced midshaft clavicular fractures in adolescents remains controversial, with some favoring surgical management and others favoring a nonoperative approach. Few studies have comprehensively assessed longer-term nonoperative outcomes. Purpose: To prospectively assess patient-reported outcomes (PROs) and radiographic remodeling ≥5 years after injury in teenagers undergoing nonoperative treatment of completely displaced clavicular fractures. Study Design: Case series; Level of evidence, 4. Methods: Adolescent patients previously enrolled in a prospective study from a single institution with nonoperatively treated, completely displaced midshaft clavicular fractures ≥5 years from injury were eligible for the study. Patients were clinically evaluated for scapular dyskinesia and strength deficits. Bilateral clavicular imaging assessed residual shortening, displacement, and angulation. PROs included the American Shoulder and Elbow Surgeons (ASES), the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH), Marx Shoulder Activity Scale, cosmesis, and return to sports data. Results: A total of 24 patients were available for the follow-up, of whom 17 (71%) consented to additional imaging. The mean cohort age at the time of injury was 14.5 ± 1.1 years, with 88% being male. At a mean follow-up of 6.1 years, all fractures had healed, with no patient requiring secondary interventions. Significant remodeling was observed across all measurements, with improvements of 70% in shortening (22.8 to 6.8 mm; P <.001), 73% in superior displacement (13.4 to 3.6 mm; P <.001), and 83% in angulation (10.4° to 1.8°; P <.001). Thirteen patients (72%) had a >2-cm initial shortening, and all remodeled to <2 cm. PROs were almost universally excellent, with mean ASES, QuickDASH, and Marx activity scores of 99 ± 3, 1 ± 3, and 20 ± 1, respectively, with 79% of patients reporting perfect scores in all 3 domains. Most patients (58%) were completely satisfied with their shoulder appearance, 38% were more satisfied than not, 1 patient (4%) was neither satisfied nor dissatisfied, and no patients were dissatisfied. All patients except 1 who were interested in sports returned to sporting activities. PROs were not associated with bony remodeling (P >.05). Conclusion: Teenaged patients with completely displaced clavicular fractures treated nonoperatively can expect excellent radiographic and clinical outcomes 5 years after injury.

Background: The current literature shows that dyslipidemia can lead to a higher incidence of rotator cuff tears (RCTs) and an increased retear rate after repair. We aimed to evaluate the influence of preoperative dyslipidemia on postoperative pain, patient-reported outcomes (PROs), active range of motion (ROM), and structural integrity. Methods: A cohort of 111 patients who underwent arthroscopic RCT repair between January 2021 and July 2022, and whose complete preoperative serum lipid data were available within one week prior to surgery was retrospectively reviewed. Dyslipidemia was defined as the presence of an increase or decrease in at least one blood lipid profile (triglycerides, total cholesterol, low-density lipoprotein, high-density lipoprotein, or non-high-density lipoprotein). There were 43 patients in the dyslipidemia group and 68 in the ortholiposis group. Patient evaluations, including pain score, PROs, and ROMs, were conducted preoperatively; at 3 and 6 months postoperatively; and at the last follow-up. Structural integrity was assessed by magnetic resonance imaging (MRI) 6 months after surgery if possible, and Sugaya type 4 or 5 was considered a retear. Propensity score matching (PSM) was used to reduce bias. Results: The RCT size, surgical technique, preoperative pain status, PROs, and active ROM were comparable between patients with dyslipidemia and those with ortholiposis. Three months after surgery, patients in the dyslipidemia group had worse average PROs (Constant score: P = 0.001; ASES score: P = 0.012; UCLA score: P = 0.015), forward flexion (P = 0.012), and internal rotation (P = 0.001) than patients in the ortholiposis group did. The difference between the two groups persisted after PSM but disappeared at the sixth month after surgery. No significant differences in pain score, PROs, or active ROMs were detected between the dyslipidemia and ortholiposis groups after a mean follow-up of 24 months. Of the 72 patients who underwent MRI, 4 retears (5.6%) were found, and all were in the ortholiposis group. There was no difference in the rate of retears between the two groups (P = 0.291) or with (P = 0.495) PSM. Conclusions: In conclusion, we found that perioperative dyslipidemia may impact initial recovery within the first 3 months following arthroscopic rotator cuff repair but may have no effect on pain, PROs, or active ROMs at a mean 2-year follow-up or rotator cuff integrity at 6 months postoperatively. Trail registration Retrospectively registered. [ABSTRACT FROM AUTHOR]

Background: This study aimed to assess if there are sex differences in the functional outcome of intravenous thrombolysis (IVT) among patients with lacunar stroke (LS). Methods: Consecutive patients admitted from 1 January 2014 to 31 January 2020 to hospitals participating in the Swiss Stroke Registry presenting with LS and treated with IVT were included. The study population was then divided into two groups based on patient sex, and a multivariable ordinal logistic regression analysis was performed to uncover sex differences in the modified Rankin Scale (mRS) score at 90 days after stroke. Results: A total of 413 patients with LS were treated with IVT: 177 (42.9%) women and 236 (57.1%) men. Women were older than men (median age 74 years, 25th-75th percentiles 67-84 years versus 70 years, 25th-75th percentiles 60-80 years, value of p 0.001) and, after adjustment for meaningful variables, showed more frequently increased odds of a higher mRS score at 90 days after stroke (adjusted odds ratio 1.49, 95% confidence interval 1.01-2.19, value of p 0.044). Conclusion: This study showed that female sex increased the odds of a worse functional response to IVT in patients with LS. Future studies should further elucidate the mechanisms underlying such sex differences. [ABSTRACT FROM AUTHOR]

Objective: We aimed to evaluate the effectiveness of modified Aberdeen Weight-Bearing Test (Knee) (AWT-K) and KSS (Knee Society Score) comparing their correlations with the Tegner Lysholm (TL) score in patellar instability patients. Methods: Patients treated for patellar dislocation were divided into two groups. The first group consisted of patients operated on for patellar instability and the second group patients followed by conservative means. Duration of follow-up, age, gender, Caton-Deschamps in)dex, and type of surgical interventions were recorded. Since the TL scoring system was previously validated in the follow-up of patellar instability treatment, the compatibility of KSS and modified AWT-K scoring systems with the TL scoring system was evaluated and their effectiveness in the follow-up of patellar instability was examined. Results: A moderate correlation was found between TL and total KSS scores.However, when the relationship between KSS subgroups ES, SS, OKS, FAS and TL is examined; a weak and moderate correlation was found between the TL scoring system and OKS, SS, and FAS. When weak and non-correlated ES and SS were excluded, there was a strong correlation between TL score and mtKSS.There was a low correlation between TL scores and AWT-K 60-second average load difference and there was a low correlation between FA and AWT-K 60-second mean load difference and ratios. Conclusion: The weak correlation of the AWT-K test for weight-bearing on the knee with findings of KSS and the TL scoring system reveals that may not be an adequate follow-up instrument for patients with patellar instability in short-term follow ups.

Background: Children with chronic liver disease (CLD) have significant impairment in physical function. Physical deconditioning and sarcopenia are two predictors of morbidity and mortality among children with CLD. Purpose: The present study was conducted to evaluate the effect of aerobic and strength training on aerobic capacity, muscle strength, anthropometric measures (height, weight, body mass index (BMI), triceps skin fold thickness (TST), mid upper arm circumference (MUAC), mid arm muscle circumference (MAMC) and mid upper leg circumference (MULC), health related quality of life (HRQOL) and fatigue in children with CLD. Methods: Eighteen children with CLD from both sexes aged from 7 to 14 years old included in the study, they were recruited from Hepatology Clinic of Children's Hospital, Cairo University. They received a designed physical therapy program of aerobic and strengthening exercises twice weekly for 8-weeks. The 6-minute walk test, hand held dynamometer (pneumatic and Lafayette hand held dynamometer), anthroplus software, pediatric quality of life inventory core scale and the pediatric multidimensional fatigue scale were used to assess aerobic capacity, grip and quadriceps strength, anthropometric measures, HRQOL and fatigue respectively pre and post treatment. Results: Comparing the changes from baseline to post-intervention, there was significant improvement in aerobic capacity, grip and quadriceps strength, HRQOL and fatigue (p < 0.05). In addition, there was significant improvement in height and weight Post treatment compared to that pretreatment (p < 0.01) while, there was no significant change in BMI, TST, MUAC, MAMC and MULC (p > 0.05). Conclusion: Aerobic and strength training can be added to rehabilitation program of children with CLD to improve their aerobic capacity, muscle strength and quality of life. [ABSTRACT FROM AUTHOR]

Objective: Occupational function assessment is essential for rehabilitation of severe mental illness but lacks comprehensive tools. Method: This study examines the psychometric properties of the Chinese versions of the Vocational Cognitive Rating Scale (VCRS) and the Work Behavior Inventory (WBI) in 60 chronic patients from a psychiatric daycare center and identifies clinical correlates of occupational function measured on the Positive and Negative Syndrome Scale (PANSS). Results: The Chinese VCRS and WBI showed adequate internal consistency, interrater and test–retest reliability, and good convergent validity with the Comprehensive Occupational Therapy Evaluation Scale. Factor analysis favored a one-factor solution of the VCRS; and a four-factor structure in the WBI including Efficiency, Social Interaction, Appropriateness, and Regularity. The VCRS and Efficiency were predicted by fewer disorganization but greater affective symptoms. Social Interaction was negatively predicted by resistance symptoms. Appropriateness was associated with all but negative symptoms. Regularity was predicted by fewer negative symptoms. Considering work behavior altogether, WBI total scores were predicted by fewer negative, fewer disorganization, and greater affective symptoms. Conclusions and Implication for Practice: Findings suggest that the Chinese VCRS and WBI have sound psychometric properties and are suitable for both clinical trials and for planning personalized rehabilitation programs. Impact and Implications: This study provided the first validation of the Vocational Cognitive Rating Scale and the Work Behavior Inventory—two functional assessment tools regarding work performance specific to patients with mental illness—in an Asian country. We derived a new factor structure for finding unique relationships between clinical profiles and each facet of various work behaviors. The findings provide evidence to support a more delicate assessment of occupational function while providing a fundamental foundation for developing future personalized rehabilitation programs.

Background and purpose: In ischemic stroke, the impact of short‐ versus long‐term blood glucose level (BGL) on early lesion pathophysiology and functional outcome has not been assessed. The purpose of this study was to directly compare the effect of long‐term blood glucose (glycated hemoglobin [HbA1c]) versus serum BGL on early edema formation and functional outcome. Methods: Anterior circulation ischemic stroke patients who underwent mechanical thrombectomy after multimodal computed tomography (CT) on admission were analyzed. Endpoints were early ischemic cerebral edema, measured by quantitative net water uptake (NWU) on initial CT and functional independence at Day 90. Results: A total of 345 patients were included. Patients with functional independence had significantly lower baseline NWU (3.1% vs. 8.3%; p < 0.001) and lower BGL (113 vs. 123 mg/dL; p < 0.001) than those without functional independence, while HbA1c levels did not differ significantly (5.7% vs. 5.8%; p = 0.15). A significant association was found for NWU and BGL (ß = 0.02, 95% confidence interval [CI] 0.006–0.03; p = 0.002), but not for HbA1c and NWU (ß = −0.16, 95% CI −0.53–0.21; p = 0.39). Mediation analysis showed that 67% of the effect of BGL on functional outcome was mediated by early edema formation. Conclusion: Aggravated early edema and worse functional outcome was associated with elevated short‐term serum BGL, but not with HbA1c levels. Hence, the link between short‐term BGL and early edema development might be used as a target for adjuvant therapy in patients with ischemic stroke. [ABSTRACT FROM AUTHOR]

Introduction: Posterior cruciate ligament (PCL) is the stronger of the two cruciate ligaments of the knee and is a constraint to posterior dislocation of the knee in 90 degrees of flexion. Damage to PCL due to bony avulsion if not treated can lead to chronic pain and patellar degeneration due to posterior subluxation of the tibia. Various modalities are there to treat PCL bony avulsion fracture, including the conservative method (in undisplaced or <5 mm displaced bony piece) and open methods, including the midline posterior approach, Burks and Schaffer approach, and Arthroscopic approach with the help of sutures and screws. The purpose of this study was to objectively evaluate the results after Burks and Schaffer's approach to tibial PCL avulsion fractures using cannulated cancellous (cc) screws with or without a washer. Methodology: This is an observational study of PCL bony avulsion fractures of 30 patients in the age group of 15–45 years admitted to Dr. S.N. Medical College and Associated Group of Hospitals, Jodhpur who were followed up for six months and were classified under Modified Meyers and Mckeever classification. Patients with associated vascular injuries and severe comorbidities were excluded. Through Burks and Schaffer's approach, PCL bony avulsion fractures were fixed with a 4 mm partially threaded cc screw with or without a washer. Their functional outcome was assessed using the Lysholm scoring system. Results: In our study, 30 patients are treated with the Burks and Schaffer method out of which excellent surgical outcomes were found in 23 (76.67%) patients and good outcomes in seven patients (23.33%). Conclusion: PCL bony avulsion fracture treated with screw fixation through the Burks and Schaffer approach has excellent clinical outcomes due to the ease of performing it with fewer complications during exposure and fixation with an easily available and affordable implant. With this method, patients reported stable knees with a good range of motion and functional outcomes. [ABSTRACT FROM AUTHOR]

Aims: A post hoc analysis of RICAMIS trial to evaluate functional outcomes in relation to patient age. Methods: Patients in RICAMIS were divided into six age groups. The primary outcome was excellent functional outcome at 90 days, defined as modified Rankin Scale (mRS) score of 0–1. Compared with patients receiving usual care alone, we investigated the association of remote ischemic conditioning (RIC) effect with functional outcomes in each group and the interaction between RIC effect and age. Results: Of 1776 patients, 498 were assigned to <60 years, 326 to 60 to <65 years, 325 to 65 to <70 years, 278 to 70 to <75 years, 206 to 75 to <80 years, and 143 to ≥80 years. Higher proportions of primary outcome were found associated with RIC in <60 years group (72.6% vs. 64.8%; adjusted risk difference [RD], 6.8%; 95% CI, −1.6% to 15.1%; p = 0.11), 60 to <65 years group (70.7% vs. 67.1%; adjusted RD, 3.1%; 95% CI, −7.2% to 13.3%; p = 0.56), 65 to <70 years group (70.5% vs. 63.6%; adjusted RD, 3.5%; 95% CI, −6.8% to 13.8%; p = 0.51), 70 to <75 years group (59.7% vs. 54.9%; adjusted RD, 4.7%; 95% CI, −7.1% to 16.4%; p = 0.61), 75 to <80 years group (61.5% vs. 55.9%; adjusted RD, 5.7%; 95% CI, −7.8% to 19.1%; p = 0.41), and ≥ 80 years group (59.2% vs. 59.7%; adjusted RD, −2.6%; 95% CI, −18.8% to 13.5%; p = 0.75). No significant interaction between RIC effect and age was found among groups. Conclusions: This is the first report that RIC effect may be attenuated with increasing age in patients with acute moderate ischemic stroke with respect to functional outcome. [ABSTRACT FROM AUTHOR]

Multimetatarsal fractures are a particular type possibly associated with worse functional outcomes. Existing studies are scarce, fragmented, and lack control for confounders. This study aimed to explore the functional prognosis of isolated closed extra-articular multimetatarsal fractures and the different outcomes between the plate-screw and K-wire fixation. This retrospective study included 79 patients who underwent surgery for isolated closed extra-articular multimetatarsal fractures from May 2017 to December 2020. We recorded baseline characteristics. The primary outcome measure was Visual Analogue Scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) score, and Foot and Ankle Outcome Score (FAOS). Exploratory correlation analysis of the variables with VAS, AOFAS score, and FAOS was performed. The differences between the plate-screw group (n = 58) and K-wire group (n = 21) were compared. Seventy-nine patients (79 feet) were included with a follow-up of (47.3 ± 12.7) months (range, 26-70). Full weight bearing time was (11.7±5.3) weeks. VAS was (1.4±1.8) points, AOFAS score was (86.4±13.3) points, and FAOS was (79.0±11.1) points. Complications were observed in 17 cases (21.5%). According to exploratory correlation analysis, VAS was weakly associated with fixation method and gender, AOFAS was weakly associated with fixation method, FAOS was weakly associated with trauma mechanism. When the plate-screw group (n = 58) was compared with the K-wire group (n = 21), we found the former was superior to the latter in terms of full weight bearing time, VAS, AOFAS score, and malunion rate (all p <.05). FAOS was nonsignificant (p =.056). Operative treatment of isolated closed extra-articular multimetatarsal fractures showed good mid-term results. Plate-screw fixation was associated with faster rehabilitation as well as a lower malunion rate. The mid-term follow-up results showed patients with plate-screw fixation had better VAS and AOFAS scores. [ABSTRACT FROM AUTHOR]

Background/Aim: The relationship between the severity of cardioembolic stroke (CES) and oral anticoagulant (OAC) treatment before stroke onset in very elderly (=80 years) patients with nonvalvular atrial fibrillation (NVAF) at high bleeding risk remains unknown. Patients and Methods: A total of 364 consecutive patients (=80 years) with CES and NVAF within 48 h following stroke onset were investigated. High bleeding risk was defined as follows: Bleeding history, renal dysfunction (creatinine clearance <30 ml/min), low body weight (=45 kg), and antiplatelet or nonsteroidal anti-inflammatory drug use. Patients were divided into two groups: High bleeding risk (n=214) and non-high bleeding risk (n=150). We assessed stroke severity and functional outcome between the two groups, and evaluated the effect of therapy with direct OAC (DOAC) on stroke severity in the high-risk group. Results: The high-risk group had a worse modified Rankin Scale (mRS) at discharge than the non-high-risk group [median: 4 (range=2-5) vs. 3 (range=1-4); p=0.02]. Patients in the high-risk group were categorized according to OAC treatment before stroke onset: No OAC (n=148), warfarin (n=46), and DOAC (n=20). The numbers of patients with National Institutes of Health Stroke Scale score (NIHSS) =8 on admission in these groups were 104 (70%), 30 (65%), and 8 (40%) (p=0.03), respectively. Multivariate analysis confirmed that DOAC therapy had a lower odds ratio (OR) for severe stroke (NIHSS =8) on admission (OR relative to no OAC=0.22, 95% confidence interval=0.08-0.62; p=0.005) and poor functional outcome (mRS =4) at discharge (OR=0.31, 95% confidence interval=0.11-0.90; p=0.03). Conclusion: Very elderly patients with CES at high bleeding risk have unfavorable functional outcomes. DOAC administration may be associated with reduced stroke severity. [ABSTRACT FROM AUTHOR]

Background The optimal treatment for acute minor ischemic stroke is still undefined. and options include dual antiplatelet treatment (DAPT), intravenous thrombolysis (IVT), or their combination. We aimed to investigate benefits and risks of combining IVT and DAPT versus DAPT alone in patients with MIS. Methods and Results This is a prespecified propensity score‐matched analysis from a prospective multicentric real‐world study (READAPT [Real‐Life Study on Short‐Term Dual Antiplatelet Treatment in Patients With Ischemic Stroke or Transient Ischemic Attack]). We included patients with MIS (National Institutes of Health Stroke Scale score at admission ≤5), without prestroke disability (modified Rankin scale [mRS] score ≤2). The primary outcomes were 90‐day mRS score of 0 to 2 and ordinal mRS distribution. The secondary outcomes included 90‐day risk of stroke and other vascular events and 24‐hour early neurological improvement or deterioration (≥2‐point National Institutes of Health Stroke Scale score decrease or increase from the baseline, respectively). From 1373 patients with MIS, 240 patients treated with IVT plus DAPT were matched with 427 patients treated with DAPT alone. At 90 days, IVT plus DAPT versus DAPT alone showed similar frequency of mRS 0 to 2 (risk difference, 2.3% [95% CI −2.0% to 6.7%]; P=0.295; risk ratio, 1.03 [95% CI 0.98–1.08]; P=0.312) but more favorable ordinal mRS scores distribution (odds ratio, 0.57 [95% CI 0.41–0.79]; P

Background Stroke is a leading cause of death worldwide, with a lack of effective treatments for improving the prognosis. The aim of the present study was to identify novel therapeutic targets for functional outcome after ischemic stroke . Methods and Results Cis‐expression quantitative trait loci data for druggable genes were used as instrumental variables. The primary outcome was the modified Rankin Scale score at 3 months after ischemic stroke, evaluated as a dichotomous variable (3–6 versus 0–2) and also as an ordinal variable. Drug target Mendelian randomization, Steiger filtering analysis, and colocalization analysis were performed. Additionally, phenome‐wide Mendelian randomization analysis was performed to identify the safety of the drug target genes at the genetic level. Among >2600 druggable genes, genetically predicted expression of 16 genes (ABCC2, ATRAID, BLK, CD93, CHST13, NR1H3, NRBP1, PI3, RIPK4, SEMG1, SLC22A4, SLC22A5, SLCO3A1, TEK, TLR4, and WNT10B) demonstrated the causal associations with ordinal modified Rankin Scale (P

Abstract Purpose To identify the effect of releasing a tourniquet before versus after wound closure in total knee arthroplasty (TKA) on blood loss, functional outcome and postoperative complications. Methodology A prospective cohort study was conducted including 53 patients from May 2023 to September 2023. All patients underwent unilateral TKA and were divided into two groups based on surgeon preference of deflating tourniquet, Group A consisted of patients in whom the tourniquet was deflated before wound closure for haemostasis and Group B consisted of patients in which tourniquet was deflated after wound closure and compressive dressing. Blood loss was evaluated via intraoperative blood loss (the number of soaked sponges/gauzes, blood in a suction bottle, total output in a suction bottle—irrigation used) and on‐field blood loss and calculated blood loss (Using Gross and Meunier's formula). The Functional outcome was evaluated using Knee injury and osteoarthritis score‐42 questions. Early postoperative complications and differences in the requirement of blood transfusions were also assessed. Results There was a significant difference in intraoperative blood loss between the two groups. The median intraoperative blood loss was 135 mL (interquartile range [IQR]: 90–149) in Group A and 56.2 mL (IQR: 45–68) in Group B (p value: 0.001). However, no difference was found between the groups in calculated blood loss using Gross and Meunier's formula. The median calculated blood loss was 439 mL (IQR: 450–813) in Group A and 508 mL (IQR: 226–671) in group B (p value: 0.981). There was no significant difference between the groups in blood transfusion requirements or functional outcomes. Conclusion Based on our results, we conclude that the intraoperative blood loss in TKA is significantly different between the groups but only represents a fraction of true blood loss (23%). The timing of releasing the tourniquet does not affect functional outcomes, blood transfusion and postoperative morbidity; hence, any time can be opted as per surgeon preference. Level of Evidence Level II, prospective comparative study.

Objectives. This study evaluated the functional outcome of patients with acetabular injuries using the Majeed pelvic score. The specific objectives were to assess any differences in functional outcomes among patients treated with early versus delayed surgery and those with or without concomitant injuries. Methodology. Patients from our institution, Baguio General Hospital and Medical Center, with acetabular injuries from January 2019 to December 2022, were included. Patients with acetabular fractures with or without other injuries were included. All available data sources were reviewed, such as charts from hospital records, patient census, and electronic medical records. Patients underwent physical therapy before discharge and were followed up. The patients’ outcomes after surgical intervention were assessed using Majeed's pelvic score. Results. Thirteen patients were included in the study with follow-ups ranging from one to three years. A functional assessment using Majeed's pelvic score with a mean of 83 points (range 72–100). The majority had good functional outcomes. Conclusions. Early surgical intervention may have no advantage over delayed surgeries regarding functional outcomes. However, concomitant injuries and complications may contribute to a poor to fair functional outcome.

IntroductionIschemic stroke is a significant global health concern, with reperfusion therapies playing a vital role in patient management. Neuron-specific enolase (NSE) has been suggested as a potential biomarker for assessing stroke severity and prognosis, however, the role of NSE in predicting long-term outcomes in patients undergoing reperfusion therapies is still scarce.AimTo investigate the association between serum NSE levels at admission and 48 h after reperfusion therapies, and functional outcomes at 90 days in ischemic stroke patients.MethodsThis study conducted a prospective cross-sectional analysis on consecutive acute ischemic stroke patients undergoing intravenous fibrinolysis and/or endovascular thrombectomy. Functional outcomes were assessed using the modified Rankin Scale (mRS) at 90 days post-stroke and two groups were defined according to having unfavorable (mRS3-6) or favorable (mRS0-2) outcome. Demographic, clinical, radiological, and laboratory data were collected, including NSE levels at admission and 48 h. Spearman’s coefficient evaluated the correlation between analyzed variables. Logistic regression analysis was performed to verify which variables were independently associated with unfavorable outcome. Two ROC curves determined the cut-off points for NSE at admission and 48 h, being compared by Delong test.ResultsAnalysis of 79 patients undergoing reperfusion treatment following acute stroke revealed that patients with mRS 3–6 had higher NIHSS at admission (p 14.2 ng/mL) and NSE48h (>26.3 ng/mL) were identified, showing associations with worse clinical outcomes. Adjusted analyses demonstrated that patients with NSE48h > 26.3 ng/mL had a 13.5 times higher risk of unfavorable outcome, while each unit increase in NIHSS24h score was associated with a 22% increase in unfavorable outcome. Receiver operating characteristic analysis indicated similar predictive abilities of NSE levels at admission and 48 h (p = 0.298). Additionally, a strong positive correlation was observed between NSE48h levels and mRS at 90 days (r = 0.400 and p

Abstract Somatic mutations related to clonal hematopoiesis of indeterminate potential (CHIP) are risk factors for stroke. The impact of DNMT3A, the most mutated gene in CHIP, on clinical functional outcomes of acute ischemic stroke (AIS) remains unclear. In a well‐characterized cohort of 8524 ischemic stroke patients, we demonstrated that DNMT3A‐driven CHIP was significantly associated with neurological disability in these patients. With a stroke mouse model of transient middle cerebral artery occlusion (tMCAO), we demonstrated that DNMT3A protein levels in the brain penumbra increased. The DNMT3A inhibitor RG108 administration amplified neutrophil proliferation in the blood, promoted neutrophil infiltration into the brain penumbra, and exaggerated proinflammatory activation in tMCAO male mice. DNMT3A inhibition also significantly increased infarct volume and worsened neurobehavioral function in tMCAO male mice. In conclusion, DNMT3A somatic mutations are associated with worsened neurological disability in some patients with AIS, potentially through increased neutrophil proliferation and infiltration in the ischemic brain region. These findings suggest a possible mechanism for proinflammatory activation and tissue damage in the affected brain tissue, highlighting the need for further research in this area.

Background Tenecteplase, a bioengineered variant of alteplase, is a new alternative thrombolytic agent. The ORIGINAL study aims to evaluate the efficacy and safety of tenecteplase versus standard care in Chinese patients with acute ischemic stroke within 4.5 hours of symptom onset. Methods This is a multicenter phase III study that employs a randomized (1:1), active‐controlled, parallel‐group, prospective, open‐label, blinded–end point design. Adult participants (aged ≥18 years) with acute ischemic stroke who are eligible for intravenous thrombolysis within 4.5 hours of symptom onset according to current guideline recommendations are recruited from ≈55 neurology clinics/stroke centers throughout China. Results The primary objective of the ORIGINAL study is to demonstrate the noninferiority of tenecteplase (0.25 mg/kg) to alteplase (0.9 mg/kg) on the basis of the proportion of patients who achieve a modified Rankin Scale score of 0 or 1 on day 90, that is, a favorable functional outcome. The prespecified noninferiority risk ratio margin is 0.937. Secondary end points include other functional outcomes and the following safety end points: adjudicated symptomatic intracerebral hemorrhage (up to 36 hours after the end of study drug administration) based on the European Cooperative Acute Stroke Study III definition; all‐cause death within 90 days; and the proportion of patients with a modified Rankin Scale score of 5 or 6 on day 90. Conclusions It is anticipated that the results of this study will contribute to the growing body of evidence for the noninferiority of tenecteplase to alteplase given within 4.5 hours of acute ischemic stroke symptom onset and support a new indication for tenecteplase in China.

Background We aim to identify the distinct lesion patterns and regions associated with functional outcome and inflammation in patients with acute ischemic stroke, and investigate whether the association between lesion patterns and functional outcome was mediated by inflammation. Methods and Results We performed nonnegative matrix factorization to derived low‐dimensional lesion patterns (atoms), and Bayesian linear regression models were applied to explore the associations of lesion patterns with inflammatory factors including high‐sensitivity C‐reactive protein and interleukin‐6, as well as functional outcome (defined as modified Rankin Scale score at 3 months). The difference distribution mean and 95% highest probability density interval (HPDI) were calculated. Mediation analysis was used to examine the mediating effects of inflammation on the relationships between lesion patterns and functional outcome. Seven lesion patterns were derived from 5914 patients with acute ischemic stroke. Lesion patterns distributed in the cortical regions were associated with inflammatory response, including atom 1 (interleukin‐6: mean, 0.113 [95% HPDI, 0.073–0.162]; high‐sensitivity C‐reactive protein: mean, 0.082 [95% HPDI, 0.038–0.123]) and atom 4 (interleukin‐6: mean, 0.113 [95% HPDI, 0.071–0.167]; high‐sensitivity C‐reactive protein: mean, 0.108 [95% HPDI, 0.058–0.165]). These lesion patterns were also significantly associated with functional outcome (atom 1: mean, 1.958 [95% HPDI, 1.538–2.383]; atom 4: mean, 2.245 [95% HPDI, 1.773–2.741]). Mediation analysis suggested that interleukin‐6 explained 15.34% and 7.47% in the association of atom 1 and atom 4 with functional outcome, respectively. Conclusions Certain lesion patterns that are associated with both inflammation and functional outcome of acute ischemic stroke, especially cortical infarction, may play a role in functional outcome through modulating inflammatory reactions.

Background and aimsPostinterventional hypothermia is a frequent complication in patients with large-vessel occlusion strokes (LVOS) after mechanical thrombectomy (MT). This inadvertent hypothermia might potentially have neuroprotective but also adverse effects on patients’ outcomes. The aim of the study was to determine the rate of hypothermia in patients with LVOS receiving MT and its influence on functional outcome.MethodsWe performed a monocentric, retrospective study using a prospectively derived databank, including all LVOS patients receiving MT between 2015 and 2021. Predictive values of postinterventional body temperature and body temperature categories (hyperthermia (≥38°C), normothermia (35°C–37.9°C), and hypothermia ( 3) after 90 days (OR 2.06, 95% CI 1.01–4.18, p = 0.045). For short-term functional outcome, patients with hypothermia had a higher discharge NIHSS (OR 1.38, 95% CI 1.06 to 1.79, p = 0.015) and a higher change of NIHSS from admission to discharge (OR 1.35, 95% CI 1.03 to 1.76, p = 0.029).ConclusionApproximately a fifth of LVOS patients in this cohort were hypothermic after MT. Hypothermia was an independent predictor of unfavorable functional outcomes. Our findings warrant a prospective trial investigating active warming during MT.

Objective. To evaluate the relationship between immunological parameters and functional outcome in patients with varying severity of ischemic stroke based on statistical methodology.Materials and methods. The prospective study included 78 patients diagnosed with ischemic stroke, who were distributed into two groups: group 1 — 38 mild stroke patients, NIHSS score < 5, group 2 — 40 moderate stroke patients, NIHSS score 5–15. Signs of stroke severity, degree of disability, cognitive decline, and activities of daily living were chosen as criteria to estimate the functional outcome by calculating the difference between the NIHSS, mRS, MoCA, and BI scales at the time of admission and on Day 12 of hospital stay. Lab tests included assessment of plasma concentrations of CXC and CC subfamilies of cytokines, interleukins and TNF-a on Day 2 of hospital stay. Machine learning algorithms, the Python programming language, the Pandas and SciPy libraries, and discriminant analysis were used for statistical processing.Results. The following parameters were found as significant: concentrations of IL-1b and MPIF-1/CCL23 for — for group 1, and concentrations of IL-16, MPIF-1/CCL23, Eotaxin-2/CCL24, Gro-a/CXCL1 and IL-8/CXCL8 for group 2 patients. Positive correlation was established between NIHSS dynamics and concentrations of TNF-a (R=0.227, P=0.001), MPIF-1/CCL23 (R=0.380, P=0.00061) and Gro-a/CXCL1 (R=0.211, P=0.00001), and between changes in mRS and concentrations of MPIF-1/CCL23 (R=0.277, P=0.00006), Gro-a/CXCL1 (R=0.211, P=0.0075) and IL-16 (R=0, 211, P=0.00001). There was a significant negative correlation between cognitive dysfunction and concentrations of Eotaxin-2/CCL24 (R=–0.378, P=0.00075), Gro-a/CXCL1 (R=–0.313, P=0.0035), and IP-10/CXCL1 (R=–0.214, P=0.00023), and between limited activities of daily living (IB) and concentrations of MPIF-1/CCL23 (R=–0.345, P=0.0024) and Gro-a/CXCL1 (R=–0.210, P=0.00001).Conclusion. Chemokines form the CC family — MPIF-1/CCL23 and Eotaxin-2/CCL24, and the CXC-Gro-a/CXCL1 and IL-16 clusters are the principal cytokines associated with the dynamics of patient’s motor and cognitive functions recovery in the acute period of ischemic stroke. Although obtained results demonstrate negative effect of increased MPIF-1/CCL23, Gro-a/CXCL1, IL-16 and Eotaxin-2/CCL24 concentrations on the improvement of motor and cognitive impairments, further studies are needed to verify the CXC and CC subfamilies chemokines as prognostic markers of patient’s functional outcome in the acute period of ischemic stroke.

Abstract Background To investigate whether accurate placement of sustentaculum tali screws have the impacts on the clinical efficacy of calcaneal fractures. Methods A retrospective analysis of 72 cases (73 feet) of calcaneal fractures from September 2015 to September 2019 treated with open reduction and internal fixation with sustentaculum tali screws was conducted. Patients were divided into the sustentaculum tali fixation group (ST group) and the sustentaculum fragment fixation group (STF group) according to the location of the sustentaculum tali screw placement. The functional outcomes at preoperative, 7 days and 1 year postoperative were collected and analyzed. Results In the ST group (40 feet), the Gissane's angle altered from (109.89 ± 12.13)° to (121.23 ± 9.34)° and (119.08 ± 8.31)° at 7 days and 1 year postoperative, respectively. For Böhler’s angles altered from (11.44 ± 5.94)°, to (31.39 ± 7.54)°, and (30.61 ± 7.94)° at 7 days and 1 year postoperative, respectively. In the STF group (33 feet), Gissane’s angle altered from (110.47 ± 14.45)°, to (122.08 ± 8.84)°, and (120.67 ± 9.07)° and Böhler’s angle altered from (11.32 ± 6.77)°, to (28.82 ± 8.52)°, and (28.25 ± 9.13)° (P 0.05). The AOFAS scores at the final follow-up of the two groups: ST group (88.95 ± 6.16) and STF group (89.78 ± 8.76); VAS scores, ST group (0.83 ± 0.98) and STF group (1.03 ± 1.59), all differences were not statistically significant (P > 0.05). Conclusion The position of sustentaculum tali screws has no significant difference on the short-term clinical outcome in patients with calcaneal fractures, while reliable fixation of screws to sustentaculum tali fragment can achieve similar clinical outcome. Level of evidence V.

Background: Subvastus approach and medial parapatellar approach are two major approaches for total knee replacement (TKR). There is no global consensus on the superiority of either approach in terms of functional outcomes. Objective: The present study aimed to evaluate the functional outcome of TKR through subvastus approach and medial parapatellar approach by using patient-reported scores at 3-, 6-, and 12-month post-operative follow-ups. Methods: This prospective cohort follow-up study included patients with knee osteoarthritis who underwent elective primary TKR either through the subvastus or medial parapatellar approaches at King Abdullah Medical City, Makkah city, Kingdom of Saudi Arabia, from January 2019 to December 2022. Scores from the self-reported Oxford Knee Score (OKS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were compared in the two groups of patients at 3-, 6-, and 12-month post-operative follow-ups. Results: A total of 98 patients were included, of which 37 underwent TKR through the subvastus approach and 61 through the medial parapatellar approach. There was an overall significant change over time in both WOMAC and OKS scores (P < 0.001). Patients who underwent the subvastus approach had significantly higher mean of WOMAC and OKS than patients with the medial parapatellar approach at the 3- and 6-month follow-ups (P < 0.05), but not at the 12-month follow-up. Conclusions: For TKR, the medial parapatellar approach results in better functional outcomes at the 3- and 6- month follow-up periods compared with the subvastus approach.

Introduction: Arteriovenous (AV) malformations (AVMs) are rare vascular developmental orders containing an arterial network draining directly into one or more veins without a capillary bed, accounting for 1.5% of total vascular anomalies. Clinical presentations include pulsating mass, pain, ulceration, bleeding, tissue necrosis, enlargement of draining vein, and venous hypertension and/or cardiac failure. Treatment modalities include surgical excision, coil embolization, and sclerotherapy. Surgical excision offers an opportunity for cure but is associated with a risk of injury to vital structures, causing permanent impairment. Due to the high-risk nature of the lesion, it is important to study the clinical presentation and management of peripheral AVM for better management of these patients. Objectives: The objective was to study the presentation, management, and postoperative outcomes in terms of recurrence and functional status of the limb after surgical management of AVMs. Patients and Methods: It was a retrospective study done for 5 years (2018–2023). Thirteen patients who underwent surgical excision of peripheral AVM were included. Recurrence and functional status were assessed by clinical evaluation during follow-up outpatient department visits. Conclusion: The mean age of presentation is 33 years, with male preponderance (70%). Seven patients had upper limb AVMs (four had forearm involvement, while the rest had elbow region involvement). Six patients had lower limb AVMs, out of which four patients had involvement of the thigh region, one had in the knee, and the other in the calf. All patients complained of difficulty in performing daily activities due to the lesion. Nine patients underwent direct surgical excision, and four patients underwent AVM embolization before surgery (three patients had coil embolization, and one had onyx embolization). The mean duration of stay in the hospital was 5 days. Three patients were advised body contour stockings at follow-up. Two patients had recurrence (one after 6 months of surgical excision and the other had prior coil embolization), and one patient (had preembolization) had continued difficulty in walking postprocedure. The rest of the patients did not develop recurrence/functional impairment. There was no postoperative mortality. Thus, surgical excision offers a chance at cure with durable, functional outcomes in patients with peripheral AVMs.

Aims: The primary aim of this study was to present the mid-term follow-up of a multicentre randomized controlled trial (RCT) which compared the functional outcome following routine removal (RR) to the outcome following on-demand removal (ODR) of the syndesmotic screw (SS). Methods: All patients included in the ‘ROutine vs on DEmand removal Of the syndesmotic screw’ (RODEO) trial received the Olerud-Molander Ankle Score (OMAS), American Orthopaedic Foot and Ankle Hindfoot Score (AOFAS), Foot and Ankle Outcome Score (FAOS), and EuroQol five-dimension questionnaire (EQ-5D). Out of the 152 patients, 109 (71.7%) completed the mid-term follow-up questionnaire and were included in this study (53 treated with RR and 56 with ODR). Median follow-up was 50 months (interquartile range 43.0 to 56.0) since the initial surgical treatment of the acute syndesmotic injury. The primary outcome of this study consisted of the OMAS scores of the two groups. Results: The median OMAS score was 85.0 for patients treated with RR, and 90.0 for patients treated with ODR (p = 0.384), indicating no significant difference between ODR and RR. The secondary outcome measures included the AOFAS (88.0 in the RR group and 90.0 for ODR; p = 0.722), FAOS (87.5 in the RR group and 92.9 for ODR; p = 0.399), and EQ-5D (0.87 in the RR group and 0.96 for ODR; p = 0.092). Conclusion: This study demonstrated no functional difference comparing ODR to RR in syndesmotic injuries at a four year follow-up period, which supports the results of the primary RODEO trial. ODR should be the standard practice after syndesmotic screw fixation. Cite this article: Bone Jt Open 2023;4(12):957–963.

Abstract Background Clonal hematopoiesis of indeterminate potential (CHIP) is a phenomenon that characterizes individuals with somatic mutations that are related to hematologic malignancy but without hematologic abnormalities. Presence of CHIP is associated with the atherosclerotic cardiovascular disease through the activation of the interleukin 6 (IL-6) pathway; however, its role on unfavorable functional outcomes in different etiologies of ischemic stroke remains unclear. We aimed to investigate the association between CHIP-related gene mutations and unfavorable functional outcomes of ischemic stroke with different etiologies. Methods We prospectively studied a cohort of 3396 stroke patients with identified etiologies, and identified CHIP and the presence of the IL6R variant (IL6R p.Asp358Ala) by whole-genome sequencing. The IL6R p.Asp358Ala coding mutation was used as a genetic inhibition for IL-6 signaling. The primary outcome was unfavorable functional outcome [(Modified Rankin Scale), mRS 2–6] at 3 months. Results Of the 3396 patients, 110 (3.2%) were CHIP carriers and the median age was 62 years (IQR, 54.0–69.0). The CHIP increased the risk of unfavorable functional outcome among patients with hyper-inflammation status of high-sensitivity C-reactive protein (hsCRP) > median levels in patients with large-artery atherosclerosis (LAA) (OR 2.45, 95% CI 1.00–5.98, p = 0.049, p interaction = 0.01). Presence of IL6R variant (IL6R p.Asp358Ala) could attenuate the risk of unfavorable functional outcome only in patients with CHIP (OR 0.30, 95%CI 0.12–0.76, p = 0.01, p interaction = 0.02), and especially in LAA patients with CHIP (OR 0.1, 95%CI 0.02–0.42, p = 0.002; p interaction = 0.001). Conclusion CHIP is associated with unfavorable functional outcomes in patients with LAA stroke and hyper-inflammation. Genetic IL-6 signaling inhibition might attenuate the risk of unfavorable functional outcomes in CHIP carriers, especially in LAA stroke patients.

Background Flexor tendon injury zone V is a multicomponent soft tissue injury involving tendons, nerves, and vessels. Outcome assessment of repair thus requires evaluation of the hand as a whole rather than solely evaluating tendon function. The purpose of this Preferred Reporting Items for Systematic Reviews and Meta-Analyses -compliant systematic review was to identify and assess the components of outcome measures used in flexor zone V.

Background: A clinical quality improvement programme named Accelerated Stroke Ambulation Programme (ASAP) was piloted in Physiotherapy Department of Tai Po Hospital from 1st October 2019 to 30th September 2020 and executed as a standard practice afterwards. The goal of ASAP was to facilitate early maximal walking ability of stroke patients in early rehabilitation phase. ASAP featured (1) proactive outcome monitoring and standardised process compliance monitoring by a patient database — Stroke Registry; (2) standardised mobility prediction by Reference Modified Rivermead Mobility Index (MRMI) Gain and (3) standardised intervention database — Stroke Treatment Library. Objective: To investigate the effectiveness of ASAP in an inpatient rehabilitation setting for stroke patients in terms of functional outcomes. Methods: The design was a retrospective comparative study to analyse the difference in functional outcomes of Pre-ASAP Group (1st October 2018 - 30th September 2019) and Post-ASAP Group (1st October 2020–30th September 2021). The primary outcome measures were MRMI, Berg’s Balance Scale (BBS), Modified Barthel Index (MBI), MRMI Gain, BBS Gain, MBI Gain, MRMI Efficiency, BBS Efficiency and MBI Efficiency. Results: There 348 subjects in Pre-ASAP Group and 281 subjects in Post-ASAP Group. Both groups had highly significant within-group improvement in MRMI, BBS and MBI ([Formula: see text]). The MRMI Gain of Pre-ASAP Group and Post-ASAP Group was 6.32 and 7.42, respectively; and the difference was significant ([Formula: see text]). The BBS Gain of Pre-ASAP Group and Post-ASAP Group was 8.17 and 9.70, respectively; and the difference was in margin of significance ([Formula: see text]). The MBI Gain of Pre-ASAP Group and Post-ASAP Group was 10.69 and 11.96, respectively; but the difference was non-significant ([Formula: see text]). The MRMI Efficiency, BBS Efficiency and MBI Efficiency of Post-ASAP Group were higher than Pre-ASAP Group but the difference was non-significant. The results of this study reflected that stroke rehabilitation programme with proactive outcome monitoring, standardised process compliance monitoring, standardised mobility prediction and standardised intervention database was practical in real clinical practice with better functional outcomes than traditional physiotherapy practice which were dominated by personal preference and experience of therapists. Conclusion: Proactive outcome monitoring, standardised process compliance monitoring, standardised mobility prediction and standardised intervention database may enhance the effectiveness in terms of functional outcomes of stroke rehabilitation programme.

Background: Aneurysmal subarachnoid hemorrhage (aSAH) remains a devastating diagnosis. A poor outcome is known to be highly dependent on the initial neurological status. Our goal was to identify other parameters that favor the risk of complications and poor outcome in patients with aSAH and initially favorable neurologic status. Methods: Consecutive aSAH cases treated at our hospital between 01/2003 and 06/2016 with the initial World Federation of Neurosurgical Societies grades I–III were included. Data on demographic characteristics, previous medical history, initial aSAH severity, and functional outcome after aSAH were collected. The study endpoints were the occurrence of cerebral infarcts, in-hospital mortality, and unfavorable outcome at 6 months after aSAH (modified Rankin scale > 3). Results: In the final cohort (n= 582), the rate of cerebral infarction, in-hospital mortality, and unfavorable outcome was 35.1%, 8.1%, and 17.6% respectively. The risk of cerebral infarction was independently related to the presence of acute hydrocephalus (adjusted odds ratio [aOR]=2.33, p<0.0001), aneurysm clipping (aOR=1.78, p=0.003), and use of calcium channel blockers concomitant to nimodipine (aOR=2.63, p=0.002). Patients' age (>55 years, aOR=4.24, p<0.0001), acute hydrocephalus (aOR=2.43, p=0.036), and clipping (aOR=2.86, p=0.001) predicted in-hospital mortality. Baseline characteristics associated with unfavorable outcome at 6 months were age (aOR=2.77, p=<0.0001), Fisher grades III–IV (aOR=2.81, p=0.016), acute hydrocephalus (aOR=2.22, p=0.012), clipping (aOR=3.98, p<0.0001), admission C-reactive protein>1mg/dL (aOR=1.76, p=0.035), and treatment intervals (aOR=0.64 per-5-year-intervals, p=0.006). Conclusions: Although cerebral infarction is a common complication in aSAH individuals with favorable initial clinical condition, >80% of these patients show favorable long-term outcome. The knowledge of outcome-relevant baseline characteristics might help to reduce the burden of further complications and poor outcome in aSAH patients who tolerated the initial bleeding event well.

(1) Background: High-energy injuries of the pelvic ring are rare. The wide application of iliosacral screw fixation of the posterior pelvic ring is relatively new. The aim of the present study was to evaluate the long-term quality of life. (2) Methods: All patients treated with an iliosacral screw for a posterior pelvic ring stabilization after high-energy trauma at a level 1 trauma center between 2005 and 2015 were included. Pelvic ring injuries were classified according to the Tile classification adapted by AO/ASIF. The clinical evaluation included the patient-oriented questionnaires surveys of the Majeed Score, Iowa Pelvic Score (IPS), Work Ability Index (WAI), SF-36, EQ5D-5L. (3) Results: A total of 84 patients were included with a median follow-up of 130.1 months (IQR 95.0–162.0 months). The median ISS was 22.5 (IQR 16.0–29.0), mean Majeed Score 83.32 (SD ± 19.26), IPS 77.88 (SD ± 13.96), WAI 32.71 (SD ± 11.31), SF-36 PF 71.25 (SD ± 29.61) and EQ5D-5L 0.83 (SD ± 0.21). There was a notably difference between uni- and bilateral pelvic fractures (p = 0.033) as well as a correlation with the ISS (p = 0.043) with inferior functional outcome measured by IPS. (4) Conclusions: Long-term follow-up of iliosacral screw fixation of unstable pelvic ring fractures showed a good quality of life and functional outcome with equal EQ5D-5L results and inferior SF-36 physical functioning compared to the German population.

Background: To investigate whether accurate placement of sustentaculum tali screws have the impacts on the clinical efficacy of calcaneal fractures. Methods: A retrospective analysis of 72 cases (73 feet) of calcaneal fractures from September 2015 to September 2019 treated with open reduction and internal fixation with sustentaculum tali screws was conducted. Patients were divided into the sustentaculum tali fixation group (ST group) and the sustentaculum fragment fixation group (STF group) according to the location of the sustentaculum tali screw placement. The functional outcomes at preoperative, 7 days and 1 year postoperative were collected and analyzed. Results: In the ST group (40 feet), the Gissane's angle altered from (109.89 ± 12.13)° to (121.23 ± 9.34)° and (119.08 ± 8.31)° at 7 days and 1 year postoperative, respectively. For Böhler’s angles altered from (11.44 ± 5.94)°, to (31.39 ± 7.54)°, and (30.61 ± 7.94)° at 7 days and 1 year postoperative, respectively. In the STF group (33 feet), Gissane’s angle altered from (110.47 ± 14.45)°, to (122.08 ± 8.84)°, and (120.67 ± 9.07)° and Böhler’s angle altered from (11.32 ± 6.77)°, to (28.82 ± 8.52)°, and (28.25 ± 9.13)° (P < 0.001). However, there was no statistically significant difference in functional outcomes at 1 week after surgery and 1 year after surgery (P > 0.05). The AOFAS scores at the final follow-up of the two groups: ST group (88.95 ± 6.16) and STF group (89.78 ± 8.76); VAS scores, ST group (0.83 ± 0.98) and STF group (1.03 ± 1.59), all differences were not statistically significant (P > 0.05). Conclusion: The position of sustentaculum tali screws has no significant difference on the short-term clinical outcome in patients with calcaneal fractures, while reliable fixation of screws to sustentaculum tali fragment can achieve similar clinical outcome.

Background: Hyponatremia is a common electrolyte disturbance in patients with neurological disease; however, its predictive role for outcome in patients with supratentorial spontaneous intracerebral hemorrhage (sICH) is controversial. This study aims to explore the association between hyponatremia within 7 days after bleeding and 90-day mortality in patients with supratentorial sICH. Methods: A retrospective analysis was conducted at our institution. Patients with sICH meeting the inclusion criteria were enrolled in this study. Multivariate regression analyses were performed to determine the predictive value of hyponatremia (serum sodium <135 mmol/L) for 90-day mortality and functional outcome. Subgroup analysis was performed based on the degree and duration of hyponatremia and therapeutic strategies. The Spearman correlation test was performed to explore the relationship between hyponatremia severity and duration with variables in a multivariate regression model. Kaplan-Meier curve was depicted to reveal the relationship between hyponatremia and mortality. The receiver operating characteristic (ROC) curve was plotted to show the diagnostic effect of the minimum concentration of serum sodium (sodiummin) on 90-day mortality. Results: A total of 960 patients were enrolled, 19.6% (188) of whom were patients with hyponatremia and 26.0% (250) had 90-day mortality. The incidence of hyponatremia was roughly 2.5 times in non-survivors compared with survivors (34.8% vs. 14.2%). Multivariate regression analysis revealed that hyponatremia was the independent predictor of 90-day mortality (OR 2.763, 95%CI 1.836-4.157) and adverse outcome (OR 3.579, 95%CI 2.332-6.780). Subgroup analysis indicated an increased trend in mortality risk with both duration (more or less than 48 h) and severity of hyponatremia (mild, moderate, and severe) and confirmed the predictive value of hyponatremia for mortality in patients undergoing surgical intervention (external ventricular drainage, craniotomy, and decompressive craniectomy; all p < 0.05). The Spearman correlation test indicated no moderate or strong relationship between hyponatremia severity and duration with other variables in the multivariate model (all |rs| < 0.4). The ROC curve suggested the moderate diagnostic performance of sodiummin for mortality in both general patients and subgroups of therapeutic method patients (AUC from 0.6475 to 0.7384). Conclusion: Hyponatremia occurring in the first 7 days after bleeding is an independent predictor of 90-day morality and adverse outcome. Rigorous electrolyte scrutiny in patients treated surgically is required. [ABSTRACT FROM AUTHOR]

Background: There is no established prognostic scoring system developed for patients with large hemispheric infarction (LHI) following decompressive craniectomy (DC) based on imaging characteristics. The present study aimed to develop and validate a new computed tomography scoring model to assess the 6-month risk of poor functional outcomes (modified-Rankin scale [mRS] score of 4-6) in patients with LHI receiving DC. Methods: This retrospective cohort study included patients at two tertiary stroke centers. A prediction model was developed based on a multivariable logistic regression. The final risk factors included the ASPECTS (Alberta Stroke Program Early Computed Tomography Score), longitudinal fissure cistern, Sylvian fissure cistern, and additional vascular territory involvement. 1,000 bootstrap resamples and temporal validation were implemented as validations for the scoring system. Results: Of the 100 individuals included in the development cohort, 71 had poor functional outcomes. The scoring model presented excellent discrimination and calibration with C-index = 0.87 for the development cohort, and C-index = 0.83 for the temporal validation cohort with non-significant Hosmer-Lemeshow goodness-of-fit test. The scoring model also showed an improved AUC compared to the ASPECTS. For each point in the score model, the adjusted risk of poor functional outcomes increase by 47.8% (OR = 1.48, p < 0.001). The scores were inversely correlated with MAP (mean arterial pressure, paired t-test, p = 0.0015) and CPP (cerebral perfusion pressure, rho = -0.17, p = 0.04). Conclusion: In patients with LHI following DC, the score system is an excellent predictor of poor functional outcomes and is associated with CPP and MAP, which might be worth considering in clinical settings after further external validation.

Introduction: Unstable acetabular fracture remains a complex fracture that requires technically demanding surgery for orthopedic surgeons. Quadrilateral plate (QP) fractures of the acetabulum are a challenging group of acetabular fractures to manage. However, the literature regarding the management of these injuries are limited. The QP is a relatively thin medial wall of the acetabulum and intra-articular; thus, anatomical reduction and stable fixation are required for satisfactory outcome. This study aims to determine the functional, radiological, and quality of life outcome of unstable acetabular fracture with QP involvement. Methods: This was a retrospective cohort study conducted at Cipto Mangunkusumo General Hospital during the period of 2010–2020. Patients with unstable acetabular fractures with and without QP involvement were included in this study. They were followed up postoperatively at 1, 6, and 12 months. Functional outcome was assessed using the Harris Hip Score (HHS), Merle D'Aubigne, and Oxford Hip Score (OHS); while radiology outcome was assessed using Matta Outcome Grading; and quality of life was assessed using the SF-36. Results: This study involved 53 subjects with a median age was 29 (18–75) years of age. Twenty-eight (52.8%) subjects had unstable acetabular fracture with QP involvement. Twenty-five (47.2%) subjects had unstable acetabular fracture without QP involvement. Twenty-five (47.2%) subjects were fixed using quadrilateral hook plate, 3 (5.7%) with infrapectineal plate, 10 (18.8%) with posterior column plate, and 15 (28.3%) with suprapectineal plate. The median intraoperative bleeding in those with unstable acetabular fracture with QP involvement was 600 (300–4000) ml, which was higher than those without QP involvement (400 [100–1700] ml). Those with QP involvement achieved anatomical reduction in 20 (71.4%) subjects. Whereas, the subjects without QP involvement achieved anatomical reduction 23 patients (92%). Subjects with QP involvement had significantly lower functional, radiological, and quality of life outcomes compared to those without quadrilateral plate involvement based on Harris Hip Score (p = 0.046), Merle D'Aubigne (0.001), Oxford Hip Score (0.001), Matta Outcome Grading (0.004), and SF-36 (0.001). Patients with quadrilateral hook plate showed no significant functional, and radiological outcome difference compared to patients with infrapectineal plate based on Harris Hip Score (p = 0.582), Merle D'Aubigne (0.698), Oxford Hip Score (1.000), and Matta Outcome Grading (1.000). In addition, we also found no significant functional, radiological, and quality of life outcome difference between posterior column plate and suprapectineal plate group based on Harris Hip Score (p = 0.200), Merle D'Aubigne (0.643), Oxford Hip Score (0.316), Matta Outcome Grading (1.000), and SF-36 (0.600). Conclusions: Patients with unstable acetabular fracture with quadrilateral plate involvement subject had significantly lower functional, radiological, and quality of life outcomes compared to those without quadrilateral plate involvement. Both quadrilateral hook and infrapectineal plates demonstrated non-significant functional and radiological outcomes difference. Posterior column plate also resulted in the same functional, radiological, and quality of life outcome compared with suprapectineal fixation. [ABSTRACT FROM AUTHOR]

Surgeons commonly perform Decompressive craniectomy (DC) to manage patients with cerebral ischemic infarction. However, there are conflicting data on the long-term functional outcomes following DC. Therefore, this study aims to determine the functional outcome of patients with cerebral ischemic infarction after DC. This prospective and retrospective cross-sectional study included 148 patients with cerebral ischemic infarction who underwent DC at Ghaem Hospital, Mashhad, Iran, from March 2011 to March 2021. The Modified Rankin Scale (mRS) assesses disability in these patients and determines the recovery and degree of long-term functional outcomes. Demographic and clinical data were extracted and recorded in a researcher-made questionnaire. In summary, the follow-up revealed a survival rate of 39.2% among patients with ischemic stroke. The comparison of the mean infarct volume in patients with various mRS scores showed that the mean infarct volume was significantly higher in patients with unfavorable functional outcomes, based on mRS scores at discharge (P = 0.05), 3 months mRS (P < 0.01), and mRS score at final follow-up (P = 0.01). Final mortality was higher in patients with higher mRS scores at discharge, after 3 months, and final follow-up (P < 0.01). Older age and infarction volume can predict mRS and mortality in patients with ischemic stroke (P < 0.01). The present study showed that mortality and mRS scores at various times are associated with infarction volume and older age in patients with ischemic stroke. [ABSTRACT FROM AUTHOR]

In the SARS‐CoV‐2 Omicron period, the pattern of pneumonia changed from primarily viral pneumonia to pneumonia mixed with bacteria in the elderly. We investigated functional outcomes at 1 year after hospital discharge in patients with primary Omicron pneumonia and pneumonia mixed with bacteria, mainly aspiration pneumonia. Functional decline rates calculated using the Barthel Index at 1 year after hospital discharge were significantly higher in the pneumonia mixed with bacteria group than the primary viral pneumonia group (42.6% vs. 20.5%, p < 0.0001). It is necessary to consider early rehabilitation and treatment in elderly patients even when the predominant strain is the Omicron variant. [ABSTRACT FROM AUTHOR]

Background: We aimed to develop a simple scoring table for predicting probability of death within 1‐year after admission to an intensive care unit. We analysed data on emergency admissions from the nationwide Finnish intensive care quality registry. Methods: We included first admissions of adult patients with data available on 1‐year vital status (dead or alive) and all five variables included in a premorbid functional status score, which is the number of activities the person can manage independently of the following five: get out of bed, move indoors, dress, climb stairs and walk 400 m. We analysed data on patient characteristics and admission‐associated factors from 2012 to 2014 to find predictors of 1‐year mortality and to develop a score for predicting probability of death. We tested the performance of this score in data from 2015. We assessed the 1‐year functional status score of survivors with data available. Results: Out of 25,261 patients, 20,628 (81.7%) patients were able to perform all five functional activities independently prior to the intensive care unit admission. At 1‐year post admission, 19,625 (77.7%) patients were alive. 1‐year functional status score was known for 11,011 patients and 8970 (81.5%) patients achieved functional status score 5, managing all five activities independently. The score based on age, sex, preceding functional status, type of intensive care unit admission, severity of acute illness and the most significant diagnoses predicted 1‐year mortality with an area under the receiver operating characteristic curve 0.78 (95% CI, 0.76–0.79). The calibration of our prediction model was good, with calibration intercept −0.01 (−0.07 to 0.05) and calibration slope 0.96 (0.90 to 1.02). Conclusion: Our score based on data available at intensive care unit admission predicted 1‐year mortality with fairly good discrimination. Most survivors achieved good functional recovery.

To assess any clinically important difference in functional outcome over 10 years after primary total knee arthroplasty (TKA). A prospective registry-based observational cohort study including 309 patients older than 60 years who underwent primary TKA. Patients were assessed at 1, 3, 5, 7 and 10 postoperative years with the Knee Society scores (KSS) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). Clinically important improvement was defined according to the minimal clinically important difference (MCID). Patients were also categorized as type A (unilateral knee osteoarthritis), type B (bilateral knee osteoarthritis) or type C (various sites of osteoarthritis). The mean age at the TKA surgery was 69.2 (SD 7.3) years, 197 (63.7%) were women. Maximum postoperative improvements in functional scores occurred at 3 postoperative years, remained relatively stable up to 5-year. There were significant decreases in all KSS and WOMAC scores at 7-year follow-up (P =.001), remained stable up to 10-year. At 10-year, functional scores were significantly higher than preoperatively (P =.001). Differences between maximum scores at 3-year and those at 10-year were significantly lesser than MCID in all scores (P =.001). In multivariate analysis, type-C patient at TKA surgery was the only significant predictor of unsuccessful KSS score and dissatisfaction at 10-year follow-up. Primary TKA provides clinically important improvements in functional and quality of life outcomes over 10-year follow-up compared to preoperatively. Although there were statistically significant declines in KSS and WOMAC scores from 3 to 10 years, the differences were lesser than the MCID. [ABSTRACT FROM AUTHOR]

Weight loss is commonly recommended before total knee arthroplasty (TKA) despite inconsistent evidence for better outcomes. This study sought to examine the impacts of preoperative weight loss on patient-reported and adverse outcomes among TKA patients supervised by a medical weight management clinic. This study retrospectively analyzed patients who underwent medical weight management supervision within 18 months before TKA comparing patients who did and did not have clinically relevant weight loss. Preoperative body mass indices, demographics, Patient-Reported Outcomes Measurement Information System physical function and pain interference scores, pain intensity scores, and adverse outcomes were extracted. Multivariable linear regressions were performed to determine if preoperative weight loss correlated with patient-reported outcomes after controlling for confounders. There were 90 patients, 75.6% women, who had a mean age of 65 years (range, 42-82) and were analyzed. There were 51 (56.7%) patients who underwent clinically relevant weight loss with a mean weight loss of 10.4% and experienced no difference in adverse outcomes. Preoperative weight loss predicted significantly improved 3-month postoperative physical function (β = 15.2 [13.0-17.3], P <.001), but not pain interference (β = −18.9 [-57.1-19.4], P =.215) or pain intensity (β = −1.8 [-4.9-1.2], P =.222) scores. We found that medically supervised preoperative weight loss predicted improvement in physical function 3 months after TKA. This weight loss caused no major adverse effects. Further research is needed to understand the causal relationships between preoperative weight loss, medical supervision, and outcome after TKA and to elucidate potential longer-term benefits in a larger sample.

Semiconstrained total elbow arthroplasty (TEA) is an established treatment for elderly patients with distal humeral fractures not amenable to stable internal fixation (unreconstructable). In recent years, there has been increasing interest in elbow hemiarthroplasty (EHA), a treatment option which does not entail restrictions on weight-bearing as opposed to TEA. These 2 treatments have not been compared in a randomized controlled trial (RCT). The aim of this study was to compare the functional outcome of EHA and TEA for the treatment of unreconstructable distal humeral fractures in elderly patients. This was a multicenter randomized controlled trial (RCT). Patients were included between January 2011 and November 2019 at one of 3 participating hospitals. The inclusion criteria were an unreconstructable distal humeral fracture, age ≥60 years and independent living. The final follow-up took place after ≥2 years. The primary outcome measure was the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Secondary outcome measures were the Mayo Elbow Performance Score (MEPS), the EQ-5D index, range of motion (flexion, extension, pronation, and supination) and grip strength. Forty patients were randomized to TEA (n = 20) and EHA (n = 20). Five patients died before completing the final follow-up, leaving 18 EHA and 17 TEA patients for analysis. There were 31 women. The mean age was 74.0 (SD, 8.5) years in the EHA group and 76.9 (SD, 7.6) in the TEA group (P =.30). The mean DASH score was 21.6 points in the EHA group and 27.2 in the TEA group (P =.39), a difference of −5.6 points (95% CI: −18.6 to 7.5). There were no differences between treatment with EHA and TEA for the mean values of the MEPS (85.0 vs. 88.2, P =.59), EQ-5D index (0.92 vs. 0.86, P =.13), extension (29° vs. 29°, P =.98), flexion (126° vs. 136°, P =.05), arc of flexion-extension (97° vs. 107°, P =.25), supination (81° vs. 75°, P =.13), pronation (78° vs. 74°, P =.16) or grip strength (17.5 kg vs. 17.2 kg, P =.89). There were 6 adverse events in each treatment group. In this RCT, both elbow hemiarthroplasty (EHA) and total elbow arthroplasty (TEA) resulted in a good and similar functional outcome for unreconstructable distal humeral fractures in elderly patients at a minimum of 2 years of follow-up.

Background and Objectives: The aim of this study was to investigate the incidence of cerebrovascular pathology in patients with chronic kidney disease and its effect on functional outcomes. Materials and Methods: In a retrospective cross-sectional study (2018–2021), the medical records of patients with acute hemorrhagic and ischemic stroke with concomitant chronic kidney disease who received treatment in Riga East University Hospital Stroke Unit were analyzed. Data were analyzed using IBM SPSS 26.0. The Kruskal–Wallis, Mann–Whitney U test, and Spearman's rank correlation coefficient methods were used. Results: The final sample consisted of 305 acute cerebrovascular pathology patients (56.4% females). Overall, 57.3% of stroke patients had second-stage chronic kidney disease with average serum creatinine levels of 104.3 mmol/L (±32.8). The functional outcome of the stroke depended on the stage of chronic kidney disease. There was a statistically significant non-linear correlation between glomerular filtration rate and NIHSS (National Institute of Health Stroke Scale) score on admission (Rho −0.194, p = 0.016), glomerular filtration rate and NIHSS score on discharge (Rho −0.186, p = 0.020), and glomerular filtration rate and modified Rankin score on admission (Rho −0.237, p = 0.003) and discharge (Rho −0.224, p = 0.05). The mean NIHSS score of ischemic stroke patients was 8.3 ± 5.9 on admission and 6.5 ± 5.8 on discharge. In the hemorrhagic stroke patient group, the mean NIHSS score was 9.5 ± 7.3 on admission and 7.1 ± 6.9 on discharge. On average, 34.0% of ischemic stroke patients had an mRS score of 5 on admission, while in the hemorrhagic stroke patient group, this figure was 41%. There was no statistical difference in the glomerular filtration rate between the thrombolyzed versus non-thrombolyzed patient groups (Mann–Whitney U test = 1457, p = 0.794). Conclusions: Chronic kidney disease is an important predictor of the severity and functional outcome of a stroke; furthermore, the early management and prevention of complications should be a top priority in the prophylaxis of this cerebrovascular pathology.

Introduction: Beyond mood abnormalities, bipolar disorder (BD) includes cognitive impairments that worsen psychosocial functioning and quality of life. These deficits are especially severe in older adults with BD (OABD), a condition expected to represent most individuals with BD in the upcoming years. Restoring the psychosocial functioning of this population will thus soon represent a public health priority. To help tackle the problem, the Bipolar and Depressive Disorders Unit at the Hospital Clínic of Barcelona has recently adapted its Functional Remediation (FR) program to that population, calling it FROA-BD. However, while scarce previous studies localize the neural mechanisms of cognitive remediation interventions in the dorsal prefrontal cortex, the specific mechanisms are seldom unknown. In the present project, we will investigate the neural correlates of FR-OABD to understand its mechanisms better and inform for potential optimization. The aim is to investigate the brain features and changes associated with FROA-BD efficacy. Methods: Thirty-two individuals with OABD in full or partial remission will undergo a magnetic resonance imaging (MRI) session before receiving FROABD. After completing the FR-OABD intervention, they will undergo another MRI session. The MRI sessions will include structural, diffusion-weighted imaging (DWI), functional MRI (fMRI) with working memory (n-back) and verbal learning tasks, and frontal spectroscopy. We will correlate the pre-post change in dorsolateral and dorsomedial prefrontal cortices activation during the n-back task with the change in psychosocial functioning [measured with the Functioning Assessment Short Test (FAST)]. We will also conduct exploratory whole-brain correlation analyses between baseline or pre-post changes in MRI data and other clinical and cognitive outcomes to provide more insights into the mechanisms and explore potential brain markers that may predict a better treatment response. We will also conduct separate analyses by sex. Discussion: The results of this study may provide insights into how FROABD and other cognitive remediations modulate brain function and thus could optimize these interventions.

Objective: Hematoma expansion (HE) is the most important therapeutic target during acute care of patients with intracerebral hemorrhage (ICH). Imaging biomarkers such as non-contrast CT (NCCT) markers have been associated with increasing risk for HE. The aim of the present study was to evaluate the influence of NCCT markers with functional long-term outcome and with HE in patients with deep (basal ganglia and thalamus) ICH who represent an important subgroup of patients at the highest risk for functional deterioration with HE due to the eloquence of the affected brain region. Methods: From our prospective institutional database, all patients maximally treated with deep ICH were included and retrospectively analyzed. NCCT markers were recorded at diagnostic imaging, ICH volume characteristics were volumetrically evaluated, and all patients received follow-up imaging within 0-48 h. We explored associations of NCCT makers with unfavorable functional outcome, defined as modified Rankin scale 4-6, after 12 months and with HE. Bias and confounding were addressed by multivariable regression modeling. Results: In 322 patients with deep ICH, NCCT markers were distributed as follows: irregular shape: 69.6%, heterogenous density: 55.9%, hypodensities: 52.5%, island sign: 19.3%, black hole sign: 11.5%, and blend sign: 4.7%. Upon multivariable regression analyses, independent associations were documented with the functional outcome for irregular shape (aOR: 2.73, 95%CI: 1.42-5.22, p = 0.002), heterogenous density (aOR: 2.62, 95%CI: 1.40-4.90, p = 0.003) and island sign (aOR: 2.54, 95%CI: 1.05-6.14, p = 0.038), and with HE for heterogenous density (aOR: 5.01, 95%CI: 1.93-13.05, p = 0.001) and hypodensities (aOR: 3.75, 95%CI: 1.63-8.62, p = 0.002). Conclusion: NCCT markers are frequent in deep ICH patients and provide important clinical implications. Specifically, markers defined by diverging intrahematomal densities provided associations with a 5-times higher risk for HE and a 2.5-times higher likelihood for unfavorable functional long-term outcome. Hence, these markers allow the identification of patients with deep ICH at high risk for clinical deterioration due to HE. [ABSTRACT FROM AUTHOR]

Background: There has been intensive research into enhancing the effects of reperfusion therapy to mitigate hemorrhagic transformation (HT) in stroke patients. Using neuroprotective agents alongside intravenous thrombolysis (IVT) appears a promising approach. Cerebrolysin is one of the candidates since it consists of neuropeptides mimicking the action of neurotrophic factors on brain protection and repair. Objectives: We looked at treatment effects of Cerebrolysin as an early add-on to IVT in stroke patients with varying HT risk. Methods: It was post hoc analysis of the CEREHETIS trial (ISRCTN87656744). Patients with middle cerebral artery infarction (n = 238) were selected from the intention-to-treat population. To stratify participants according to their HT risk, the DRAGON, SEDAN and HTI scores were computed for each eligible subject using on-admission data. The study endpoints were any and symptomatic HT, and functional outcome measured with the modified Rankin Scale (mRS) on day 90. Favorable functional outcome (FFO) was defined as an mRS ≤2. The performance of each stratification tool was estimated with regression approaches. Heterogeneous treatment effect analysis was conducted using techniques of meta-analysis and the matching-smoothing method. Results: The HTI score outperformed other tools in terms of HT risk stratification. Heterogeneity of Cerebrolysin treatment effects was moderate (I2, 35.8%--56.7%; H2, 1.56--2.31) and mild (I2, 10.9%; H2, 1.12) for symptomatic and any HT, respectively. A significant positive impact of Cerebrolysin on HT and functional outcome was observed in the moderate (HTI = 1) and high (HTI ≥2) HT risk patients, but it was neutral in those with the low (HTI = 0) risk. In particular, there was a steady decline in the rate of symptomatic (HTI = 0 vs. HTI = 4: by 4.3%, p = 0.077 vs. 21.1%, p < 0.001) and any HT (HTI = 0 vs. HTI = 4: by 1.2%, p = 0.737 vs. 32.7%, p < 0.001). Likewise, an mRS score reduction (HTI = 0 vs. HTI = 4: by 1.8%, p = 0.903 vs. 126%, p < 0.001) with a reciprocal increase of the fraction of FFO patients (HTI = 0 vs. HTI = 4: by 1.2% p = 0.757 vs. 35.5%, p < 0.001) was found. Conclusion: Clinically meaningful heterogeneity of Cerebrolysin treatment effects on HT and functional outcome was established in stroke patients. The beneficial effects were significant in those whose estimated on-admission HT risk was either moderate or high. [ABSTRACT FROM AUTHOR]

Introduction: Glaucoma may be related to ischemic stroke (IS) and poor outcomes after IS in observational studies, while the causal association remains unclear. Methods: We obtained single-nucleotide polymorphisms (SNPs) related to glaucoma from the genome-wide association study (GWAS) conducted by the FinnGen consortium. The GWAS included a total of 13,614 cases and 295,540 controls. The summary-level datasets regarding IS were collected from the MEGASTROKE consortium, including 34,217 cases and 406,111 controls. Furthermore, we acquired summary statistics datasets for functional outcomes following IS from the GWAS meta-analysis conducted by the GISCOME consortium, which involved 6,021 individuals. The genetic association estimates for functional outcomes at 90 days after IS were evaluated by the modified Rankin Score (mRS), including 3,741 cases with good functional outcomes (mRS = 0–2) and 2,280 subjects with poor functional outcomes post-stroke (mRS = 3–6). Inverse variance weighting (IVW) was used as the primary method, complemented by sensitivity analyses for pleiotropy and increasing robustness. Results: Genetically, glaucoma is associated with an increased risk of IS (odds ratio [OR] = 1.08, 95% confidence interval [CI] = 1.02–1.14, p = 0.0039), as well as poor prognosis after IS with adjustment for severity (OR = 1.64; 95% CI = 1.27–2.13, p = 0.0001) and functional outcome after IS (OR = 1.45, 95% CI = 1.12–1.87, p = 0.0038). Through sensitivity analyses, we confirmed the robustness of the results. In addition, we did not identify any causal association between IS, functional outcome after IS, and glaucoma in reverse analysis. Conclusion: Our study provides evidence suggesting potential genetic causal effects of glaucoma on an increased risk of IS, as well as a poor functional outcome following IS. Future studies are necessary to confirm these findings. [ABSTRACT FROM AUTHOR]

Introduction/objectives: No consensus has been reached on which is better in terms of functional outcomes between simultaneous bilateral and unilateral total knee arthroplasty (TKA). As patient characteristics, such as age, sex, and body mass index, have significant effects on functional outcomes after TKA, these factors should be matched before comparisons are made. This study aimed to compare time courses in functional outcomes between simultaneous bilateral TKA and unilateral TKA after matching the patient characteristics. Materials and methods: In this retrospective study, the clinical records of patients admitted to a hospital were reviewed. Of 425 patients, 43 underwent simultaneous bilateral TKA, whereas 382 underwent unilateral TKA. Propensity score matching was performed for age, sex, and body mass index between simultaneous bilateral and unilateral TKA patients. Therapists measured pain intensity, knee extensor strength, and knee-specific functional outcomes by using the new knee society score, including total score, symptoms, patient satisfaction, patient expectations, and functional activities preoperatively and 3 and 12 months postoperatively. Two-way repeated analysis of variance was performed to compare the time courses in functional outcomes between simultaneous bilateral and unilateral TKA. Results: After propensity score matching, 40 patients each for underwent bilateral TKA and unilateral TKA were selected. Knee extensor strength in simultaneous bilateral TKA patients was significantly lower than that in unilateral TKA patients at 3 months postoperatively (p = 0.04). A significant interaction was observed between the effects of time and group on knee extensor strength (F [1, 78] = 3.338; interaction: p = 0.042; η2 = 0.052). No significant interactions were found among the other variables measured. Conclusions: Patients who underwent simultaneous bilateral TKA should undergo postoperative rehabilitation focused on alleviating delayed recovery in knee extensor strength during the acute phase.

Background: Lumbar spinal canal stenosis is one of the most common cause of chronic back pain in middle aged and elderly patients. The incidence of acquired lumbar stenosis is approximately 1 per 1000 in individuals older than 65 years. Aim: to find the functional outcome following posterior decompression for lumbar canal stenosis using spinaplasty technique. Material and methods: Present study was a observational study done in department of orthopaedics in tertiary care hospital. Totally 22 patients were included in the study out of which 2 patients were excluded due to loss of follow up. All patients underwent wide posterior decompression surgery at respective levels using spinaplasty technique. Wound was inspected every 3 days and IV antibiotics (cefoperazone+ sulbactam) was given for the first 3 days which were then changed to oral antibitotics(ceftriaxone) following surgery. No patient had surgical site infections/dural leak/post operative fresh neurological deficits. Surgical staples were removed on post operative day12 patient were mobilized using lumbar brace. Results: The mean intensity of back pain pre operatively was 5.05, post operatively it was reduced to 3.00 at 1 month, 2.35 at 3months and 1.95 at 6months follow up. Conclusion: The described technique wide posterior decompression using Spinaplasty technique for lumbar canal stenosis preserves the posterior ligamentous complex by repairing the median structures i.e spinous process, interspinous ligament and supraspinous ligament by lifting them as a single piece and repairing after decompression.
