Purpose: The bone strain index (BSI) is a marker of bone deformation based on a finite element analysis inferred from dual X-ray absorptiometry (DXA) scans, that has been proposed as a predictor of fractures in osteoporosis (i.e., higher BSI indicates a lower bone's resistance to loads with consequent higher risk of fractures). We aimed to investigate the association between lumbar BSI and vertebral fractures (VFs) in acromegaly., Methods: Twenty-three patients with acromegaly (13 males, mean age 58 years; three with active disease) were evaluated for morphometric VFs, trabecular bone score (TBS), bone mineral density (BMD) and BSI at lumbar spine, the latter being corrected for the kyphosis as measured by low-dose X-ray imaging system (EOS®-2D/3D)., Results: Lumbar BSI was significantly higher in patients with VFs as compared to those without fractures (2.90 ± 1.46 vs. 1.78 ± 0.33, p = 0.041). BSI was inversely associated with TBS (rho -0.44; p = 0.034), without significant associations with BMD (p = 0.151), age (p = 0.500), BMI (p = 0.957), serum IGF-I (p = 0.889), duration of active disease (p = 0.434) and sex (p = 0.563)., Conclusions: Lumbar BSI corrected for kyphosis could be proposed as integrated parameter of spine arthropathy and osteopathy in acromegaly helping the clinicians in identifying patients with skeletal fragility possibly predisposed to VFs., (© 2024.

Background: Bone health management in premenopausal women with breast cancer (BC) under hormone-deprivation therapies (HDTs) is often challenging, and the effectiveness of bone-active drugs is still unknown., Methods: This retrospective multicenter study included 306 premenopausal women with early BC undergoing HDTs. Bone mineral density (BMD) and morphometric vertebral fractures (VFs) were assessed 12 months after HDT initiation and then after at least 24 months., Results: After initial assessment, bone-active drugs were prescribed in 77.5% of women (151 denosumab 60 mg/6 months, 86 bisphosphonates). After 47.0 ± 20.1 months, new VFs were found in 16 women (5.2%). Vertebral fracture risk was significantly associated with obesity (odds ratio [OR] 3.87, P = .028), family history of hip fractures or VFs (OR 3.21, P = .040], chemotherapy-induced menopause (OR 6.48, P < .001), preexisting VFs (OR 25.36, P < .001), baseline T-score less than or equal to -2.5 standard deviation (SD) at any skeletal site (OR 4.14, P = .036), and changes at lumbar and total hip BMD (OR 0.94, P = .038 and OR 0.88, P < .001, respectively). New VFs occurred more frequently in women untreated compared to those treated with bone-active drugs (14/69, 20.8% vs 2/237, 0.8%; P < .001) and the anti-fracture effectiveness remained significant after correction for BMI (OR 0.03; P < .001), family history of fractures (OR 0.03; P < .001), chemotherapy-induced menopause (OR 0.04; P < .001), and preexisting VFs (OR 0.01; P < .001)., Conclusions: Premenopausal women under HDTs are at high risk of VFs in relationship with high BMI, densitometric diagnosis of osteoporosis, preexisting VFs, and family history of osteoporotic fractures. Vertebral fractures in this setting might be effectively prevented by bisphosphonates or denosumab., Competing Interests: Conflict of interest: R.P. received consultancy fees from Roche, Novartis, Eli Lilly, Daiichi Sankyo, Gilead, Eisai, and Accord, outside the submitted work.

Background: The increasing amount of revision surgeries in total hip arthroplasty (THA) represents a burden for orthopedic surgeons given the complexity and unpredictability of this kind of surgery. The aim of the current study was to develop a new radiographic classification of acetabular bone defects stratify the severity of the lesion and to suggest the surgical strategy to address it., Methods: Radiographs of 151 consecutive patients who underwent acetabular revision surgery in our institution were collected to develop a new classification that groups the acetabular bone defects in three zones (A, B and C). The performance to predict treatment and inter- and intra-rater agreement were evaluated., Results: The ability of the newly proposed classification to predict treatment was 87.3% (k weighted: 0.65). The inter-rater reliability was 90.1% (k: 0.81), and the intra-rater reliability between the two sets of evaluations performed by the observer at 1-month distance was 97.5% (k: 0.94)., Conclusions: The newly proposed classification was able to characterize the extent of acetabular bone defects and predict pre-operatively the appropriate surgical treatment strategy in 87.3% of cases. It showed a strong agreement among raters and an almost perfect agreement among different measurements at 1 month distance. This new tool could be used in the preoperative assessment to drive the use of secondary level image examinations and the type of surgical management., (© 2024.

Objective: The objectives of the study were to correlate live birth rate with the initial level of β-hCG in all patients undergoing embryo transfer and develop a predictive model of live birth based on patients' and assisted reproductive technology (ART) characteristics., Study Design: Single-center retrospective cohort study, including a total of 7587 positive first serum β-hCG from women who performed fresh and frozen embryo transfer. Twenty-one variables related to patient characteristics and treatment modalities were analyzed by step-wise univariate analysis followed by multivariate analysis. The study included women between 18 and 45 years with a positive (>20 IU/L) serum β-hCG between January 2011 and December 2020 while it excluded cycles from donation of gametes, PGT and >3 embryos transferred simultaneously., Main Results and the Role of Chance: Among the positive serum β-hCG measurements 5085 (67.0 %) resulted in live births. β-hCG was higher in the live birth group (691 IU/L) compared to the failed pregnancies group (304 IU/L) (p500 IU/mL provided a positive predictive value for live birth of 85.3 % (95 %CI 84.0-86.4). Failed pregnancies were more common among older maternal and paternal age. Previous abortions were more common in the failed pregnancies group (25.0 %) compared to the live birth group (19.4 %). The most common indication to treatment was male infertility, accounting for a larger portion in the live birth group (41.7 %). At multivariate analysis, the factors independently associated with live birth were: first serum β-hCG (OR 1.35, 95 %CI 1.32-1.37), maternal age (OR 0.93, 95 %CI 0.91-0.95), previous abortions (OR 0.77, 95 % CI 0.68-0.88). The number of embryos transferred showed a positive correlation below a maternal age of 39 (<35 years old OR 1.60, CI 95 % 1.32-1.94; <39 years old OR 1.27 CI 95 % 1.09-1.47). The prediction model incorporating these four variables resulted in a sensitivity and specificity with an area under the ROC curve of 0.798., Conclusion: The study confirms the importance of the first value of β-hCG and proposes a predictive model that takes into account maternal age, number of embryos transferred, and obstetric history, thereby aiding in couples' counseling and ultimately improve patients' care., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Preoperative malnutrition is a significant factor in patients with pancreatic tumors undergoing pancreaticoduodenectomy. The aim of this study was to assess the association between preoperative malnutrition and delayed discharge within a ten-day timeframe and potential correlations between preoperative malnutrition and postoperative surgical complications., Methods: A retrospective cohort study was conducted, recruiting a final sample of 79 patients with benign or malignant cephalic pancreatic tumors from 2015 to 2022. The risk of malnutrition was assessed using the Malnutrition Universal Screening Tool, while length of hospital stay and relevant clinical data were extracted from clinical documentation., Results: The preoperative malnutrition risk was high in 21.52% of the sample, moderate in 36.71%, and low in 41.77%. Body mass index (BMI) ( p = 0.007) and postoperative surgical complications ( p < 0.001) were significantly correlated with delayed discharge. No statistically significant differences were found between levels of malnutrition risk and delayed discharge ( p = 0.122), or postoperative surgical complications ( p = 0.874)., Conclusions: Postoperative complications and BMI emerge as significant risk factors. The limited sample size may have compromised the collection of homogeneous and significant data. Future studies should evaluate the implementation of personalized nutritional screening tools, nutritional assessment plans, and the involvement of specialized health professionals.

Aims: To evaluate the determinants of cardiovascular (CV) protection in men and women treated with glucagon-like peptide-1 receptor agonists (GLP1-RA)., Methods: Retrospective cohort study of 550 patients (43% women), with and without established CV disease, followed at a single center after the first prescription of a GLP1-RA. We analyzed the determinants of major adverse cardiovascular events (MACE) in men and women., Results: The rate of MACE was similar between sexes. In primary prevention, among men, older age (HR 1.13, 95 % C.I. 1.05-1.22; P = 0.001) and GLP-1 RA withdrawal by time (HR 2.77, 95 % C.I. 1.15-6.68; P = 0.023) increased the HR for MACE. Among women, significant predictors of MACE were diabetes duration (HR 1.05, C.I. 1.01-1.10; P = 0.020), GLP-1 withdrawal by time (HR 2.84, 95 % C.I. 1.13-7.10; P = 0.026) and BMI at GLP-1 RA withdrawal (HR 1.08, 95 % C.I. 1.01-1.15; P = 0.026). For individuals with prior CV disease, the HR for MACE was solely impacted by GLP-1 withdrawal over time in males (HR 2.18, 95 % C.I. 1.10-4.30; P = 0.025) and by older age at GLP-1 RA initiation (HR 1.17, 95 % C.I. 1.03-1.33; P = 0.015) in females., Conclusions: Although MACE rates were similar, the factors contributing to MACE differed by sex., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

Systematic reviews represent a fundamental study design, providing the highest level of evidence across diverse research inquiries, encompassing both public health and clinical research and practice. However, for healthcare professionals, the process of selecting, synthesizing, and interpreting evidence can be challenging, and requires specialized skills. Therefore, it is imperative to explore innovative solutions aimed at simplifying and making the traditional systematic review process more accessible while ensuring the validity and reliability of results. In this perspective, our research objective is to develop a systematic review framework that, while maintaining a rigorous methodological approach, streamlines the process for healthcare professionals. This study describes such approach in every phase, from the collection of evidence to the writing of the text, creating a guide for the healthcare professional who approaches this type of research. The qualitative and organizational analysis tools are also described, providing useful information for the use of non-paid programs. This systematic review aims to develop a framework with a rigorous methodological approach that allows simplify the process for clinicians and healthcare professionals. The implementation of this methodology in clinical practice offers new perspectives to ensure a thoughtful consideration and application of scientific evidence and opens the way to innovative and easily accessible solutions to facilitate the conduct of systematic reviews in the clinical care setting., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Background: The number of patients presenting with periprosthetic hip fractures has increased in recent decades., Methods: Patients who underwent hip revision arthroplasty procedures for Vancouver type B2 and B3 fractures between 2010 and 2021 were included. The primary intended outcome of this study was to determine the reintervention-free survival rate. The secondary intended outcome was to determine clinical and radiographic assessment outcomes at the time of follow-up, and the correlation between time to surgery and postoperative Harris hip score (HHS)., Results: A total of 49 patients with mean age of 71.2 ± 2.3 (37-88) years old were included. Overall, the Kaplan-Meier method estimated a survival rate of 95.8% (CI 84.2% to 98.9%) at one year, 91.1% (CI 77.9% to 96.6%) at two years, and 88.5% (CI 74.4% to 95.1%) at three, and up to 10, years. The mean limb length discrepancy (LLD) improved from -13.3 ± 10.5 (range -39 to +10) mm at the preoperative stage to -1.16 ± 6.7 (range -17 to +15) mm, p < 0.001 postoperative. The mean HHS improved from 31.1 ± 7.7 (range 10 to 43) preoperative to 85.5 ± 14.8 (range 60 to 100), p < 0.001 postoperative. Postoperative HHS was not affected by preoperative time to surgery., Conclusions: Revision arthroplasty is an effective treatment for Vancouver type B2 and B3 fractures.

Background/scope: Stroke is one of the main causes of death, especially when associated with dysphagia. Hence, the assessment of nutritional status and aspiration risk is important to improve clinical outcomes. The aim of this systematic review is to identify which are the most suitable dysphagia screening tools in chronic post-stroke patients., Methodology: A systematic literature search was conducted for articles published from 1 January 2000 to 30 November 2022 in the Cochrane Library, PubMed, Embase, CINAHL, Scopus and Web of Science databases, including primary studies providing quantitative or qualitative data. Additionally, a manual search was conducted scanning the reference lists of relevant articles and Google Scholar was searched to retrieve additional records. The process of screening, selection and inclusion of the articles, as well as the assessment of risk of bias and methodological quality, were conducted by two reviewers., Results: Out of the 3672 records identified, we included 10 studies, mostly (n=9) cross-sectional, evaluating screening for dysphagia in 1653 chronic post-stroke patients. Volume-Viscosity Swallow Test was the only test applied in multiple studies with adequate sample size, demonstrating high diagnostic accuracy (sensitivity=96.6%-88.2%; specificity=83.3%-71.4%) compared with the videofluoroscopic swallowing study., Conclusions: Dysphagia is an important complication in chronic post-stroke patients. Early identification of this condition through screening tools with adequate diagnostic accuracy is of paramount importance. The limited number of studies available and their small sample sizes may be a limitation to this study., Prospero Registration Number: CRD42022372303., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Purpose: There is growing interest around short stems as they provide a less invasive approach for total hip arthroplasty preserving bone stock for a possible revision surgery if required. The main purpose of this work was to assess the long-term performance of an uncemented metaphyseal short stem in terms of survival rate and in addition its clinical and radiological outcomes., Materials and Methods: From January to December 2010, we prospectively enrolled all consecutive patients undergoing primary total hip arthroplasty with an uncemented metaphyseal short stem in our institution with a minimum follow-up of 10 years. The radiographic features investigated were the varus-valgus stem orientation, areas of osteolysis and radiolucencies, stress shielding, and heterotopic calcifications. The clinical outcomes were measured using the HHS., Results: A total of 163 patients (172 hips) were finally included and the measured survival rate at 10 years was 99.6%. The average HHS increased from 55.0 preoperatively to 97.8 at the last follow-up (p < 0.0001). Among them, 137 patients (164 hips) were also available for radiographic assessment. Mild varus malalignment was observed in 40% of cases and remained stable in the serial X-rays and was not associated with step loosening. Mild stress shielding was observed around 13 stems (9%) and moderate only around 3 implants., Conclusion: In conclusion, the uncemented metaphyseal short stems showed excellent survival and clinical results at 10 years and at a radiographical level very low stress shielding was observed; moreover, besides the high frequency of varus alignment the implanted stems was not associated with revision surgery or with worse clinical outcomes., (© 2023.

Purpose: Endoscopic endonasal transsphenoidal approach (Endonasal approach) is commonly used to treat pituitary adenomas. The extent of dissection possibly changes the anatomy and the physiology of the nasal cavities and could give rise to post-operative morbidity and the quality of life (QoL). The purpose of this study was to investigate sinonasal morbidity and general QoL in patients who underwent surgery for treatment of pituitary adenoma, comparing Endonasal and endoscopic trans-septal transsphenoidal approach (Trans-septal approach)., Methods: A prospective observational study, recruiting 40 patients undergoing surgery for pituitary adenoma, 20 via Endonasal approach and 20 via Trans-septal approach at our institution. Surveys with Sinonasal Outcome Test-22 (SNOT-22), Chronic Sinusitis Survey (CSS), and Short Form Health Survey 36 version 2 (SF-36v2) were obtained to collect QoL data pre- and postoperatively., Results: All the 40 patients completed the questionnaires. At 6 months postoperatively, the SNOT-22 and CSS score shows significant improvements both in Endonasal approach (p = 0.01) and in Trans-septal approach (p = 0.02). No significant difference in sinonasal morbidity is observed between the two groups for SNOT-22 (p = 0.13) and CSS scores, except for sinus headache (p = 0.49), with a better score in Endonasal approach. The mean SF-36v2 scores remain the same in pre- and post-operative periods, but an improvement in time is seen in general health (p = 0.027), and general health compared to one year ago (p < 0.001)., Conclusions: Endoscopic transsphenoidal surgery has negligible morbidity and does not negatively affect the nasal function in the long term. Endonasal approach and Trans-septal approach are comparable in terms of morbidity outcomes and general QoL, leaving the choice of the approach to the surgeon preference., (© 2023.

Purpose: To describe the efficacy and persistence of injectable calcium hydroxyapatite (CAHY) to correct orbital volume deficit in postenucleation socket syndrome., Methods: An observational study was conducted as a clinical review of all patients in the authors' practice who received injectable CAHY placed in the extraconal and intraconal space to increase orbital volume with a 10-year follow up. The amount of CAHY to be injected was defined according to the degree of orbital volume deficit. Patients previously treated with radiotherapy or with a conjunctival fornix insufficient to accommodate the external prosthesis were excluded. All the patients with at least 10 years of follow up were included in the study., Results: Thirty-one postenucleation socket syndrome patients received injectable CAHY for orbital volume augmentation, with a 10-year follow up. The mean amount of preoperative relative enophthalmos measured by Hertel's exophthalmometry was 14.16 ± 2.15. An increase in the mean orbital volume of 3.35 ± 0.91 at 6 months and 2.97 ± 1.35 at 10 years was obtained. The mean follow-up was 219 ± 18 months (range, 184-240). Patients demonstrated clinical and cosmetic improvement that was observed to continue for 10 years. The complications were peribulbar ecchymosis, 2 extrusions of the internal prosthesis, and 2 ptosis., Conclusions: Injectable CAHY provides safe, simple, repeatable, and cost-effective technique to treat volume deficiency in the enophthalmic orbit in the long term. The volume augmentation obtained with this semipermanent filler demonstrated a lasting effect in the orbit with negligible loss of volume at 10 years., Competing Interests: The authors have no financial or conflicts of interest to disclose., (Copyright © 2023 The Author(s).

Background: Tracheal stenosis represents a fearsome complication that substantially impairs quality of life. The recent SARS-CoV-2 pandemic increased the number of patients requiring invasive ventilation through prolonged intubation or tracheostomy, increasing the risk of tracheal stenosis. Study design and methods: In this prospective, observational, multicenter study performed in Lombardy (Italy), we have exanimated 281 patients who underwent prolonged intubation (more than 7 days) or tracheostomy for severe COVID-19. Patients underwent CT scan and spirometry 2 months after hospital discharge and a subsequent clinical follow-up after an additional 6 months (overall 8 months of follow-up duration) to detect any tracheal lumen reduction above 1%. The last follow-up evaluation was completed on 31 August 2022. Results: In the study period, 24 patients (8.5%, CI 5.6-12.4) developed tracheal stenosis in a median time of 112 days and within a period of 200 days from intubation. Compared to patients without tracheal stenosis, tracheostomy was performed more frequently in patients that developed stenosis (75% vs 54%, p = 0.034). Tracheostomy and alcohol consumption (1 unit of alcohol per day) increased risk of developing tracheal stenosis of 2.6-fold ( p = 0.047; IC 0.99-6.8) and 5.4-fold ( p = 0.002; CI 1.9-16), respectively. Conclusions : In a large cohort of patients, the incidence of tracheal stenosis increased during pandemic, probably related to the increased use of prolonged intubation. Patients with histories of prolonged intubation should be monitored for at least 200 days from invasive ventilation in order to detect tracheal stenosis at early stage. Alcohol use and tracheostomy are risk factors for developing tracheal stenosis.
