Recognition of patients at high risk (HR) for breast cancer allows earlier screening and opportunities for risk reduction. We compare patients referred to our breast clinic as HR vs referrals for other reason (ROR) and found to be HR. We evaluate under-recognized factors and treatment differences. A retrospective chart review of patients found to be HR but referred for any reason to our breast clinic from July 2012 to December 2022 was performed. Referral reason, demographics, hormonal history, family history, and other risk factors were evaluated and compared (HR vs ROR). While other risk models were used for screening, Gail and Tyrer-Cuzick version 7 (TCv7) were used for comparison. Breast imaging received, hormonal therapy, and genetics referral evaluations were compared. 195 patients were referred to our breast team, 113 (58%) were referred as HR while 82 (42%) were ROR. Average age was 47 years old. 175 (91%) were Caucasian. 74 (65.5%) were referred for genetic testing, and 32 (26%) tested positive for a genetic mutation (n = 10, 12% ROR). 67 (35%) were recommended chemoprevention (n = 32, 16.4% took chemoprevention). 6 (3.1%) underwent prophylactic mastectomies and 163 (85%) had supplemental breast imaging. Comparison of HR vs ROR did not show significant differences in hormonal factors or treatments received; however, TCv7 was higher in the group referred as HR ( P < .001). Our study showed that HR patients are more commonly referred secondary to family history but undergo similar treatments as those ROR. Accessibility to screening tools and education of risk factors, especially in minorities and those not otherwise being screened, may help better recognize HR., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

The creation of a blowhole colostomy can be an effective option for patients with large bowel obstruction and severe abdominal disease. However, they are often difficult to manage secondary to poor appliance fitting, peristomal dermatitis, and pain. In 2021, a case series describing a novel technique using a Dacron Vascular Prosthesis (VUP medical, Brno, Czech Republic) sutured to the mucocutaneous junction to help with stoma management was described. In the following case study, we share our experience with placement of a Hemashield Gold Dacron Graft (Maquet Cardiovascular, LLC, Wayne, NJ, USA) as a last resort in the management of a blowhole colostomy in a patient with large bowel obstruction secondary to metastatic carcinoid tumor. Compared to the previously described technique, we used a shorter graft, non-absorbable suture (Nylon, Ethicon, Cincinnati, OH, USA) and took larger bites of the mucocutaneous junction to achieve improved quality of life., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: Medical malpractice represents a significant economic cost in health care. Increasingly large damage claims by professional athletes against physicians have raised concerns about the medicolegal challenges in caring for high-level athletes., Methods: An online proprietary legal research database was queried for lawsuits related to malpractice in the care of professional and amateur athletes from 1992 to 2023. Demographics of plaintiffs and defendants, details of lawsuit filings, and damages claimed were recorded for all cases, settlements, and jury verdicts. Descriptive statistics, linear regression, as well as univariate analysis of demographic factors and damage claims in inflation-adjusted 2023 dollars was performed., Results: Eighty-eight lawsuits were recorded from 1992 to 2023. The sum of indemnities exceeded 186 million in 2023 inflation-adjusted United States Dollars. Football players were the most commonly represented athletes (n = 26) and represented 49% of total financial awards. Fourteen cases (16%) involved treatment of the upper extremity. Professional and collegiate level of play was associated with higher damages in favor of plaintiffs when compared to other levels of play. No other demographic was associated with higher financial awards. Linear regression showed a significant positive trend with an increasing inflation-adjusted compensation for plaintiff verdicts in the last 30 years., Conclusions: There is an increasing medicolegal financial risk associated with the care of athletes. This is higher in collegiate and professional levels of play. As physicians, insurers and institutions adjust to these financial risks, care must be taken to avoid ramifications on the availability and quality of care provided to athletes. Shoulder and elbow surgeons may consider additional preoperative counseling, legal waiver forms regarding malpractice claims, and advocacy for medical malpractice reforms in the care of athletes with high earning potential to mitigate these increasing financial risks., (Copyright © 2024 Journal of Shoulder and Elbow Surgery Board of Trustees.

Background: Due to the variability in evidence supporting either trans-syndesmosis fixation or deltoid ligament repair in unstable ankle fractures with medical clear space (MCS) widening makes it unclear which surgical technique leads to the best patient outcomes. The goal of our systematic review and meta-analysis was to compare clinical outcomes of trans-syndesmotic fixation versus anatomic deltoid ligament repair in the management of unstable ankle fractures with MCS widening., Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were utilized in this study. A comprehensive and systematic search was conducted using the PubMed, Embase, Web of Science and Cochrane Library databases. Outcomes investigated in this review included the rates of syndesmotic malreduction, removal of hardware, postoperative complications including wound issues, and functional/pain scores., Results: A total of five level-3 studies were selected in this review, with 280 unstable ankle fractures with MCS widening: 165 for the trans-syndesmotic fixation group and 115 for the anatomic deltoid ligament repair group. Three out of five studies evaluated syndesmotic malreduction using CT. Compared to the trans-syndesmosis fixation group, the deltoid repair group showed significant lower rates of syndesmotic malreduction rates and removal of hardware: 6.5 % (4/61) Vs. 27 % (16/59) (RR=0.26, 95 % CI=[0.10, 0.68]), and 2.6 % (3/115) Vs.54.5 % (90/165) (RR=0.06, CI=[0.02, 0.14]), respectively. No significant differences were found between the two groups in postoperative wound complications, reoperations, and functional scores including AOFAS and VAS pain score., Conclusions: Based on our findings, anatomic deltoid ligament repair was associated with a lower rate of syndesmotic malreduction and the need for hardware removal while there was no significant difference in terms of postoperative wound complications, reoperation, AOFAS score, or VAS pain score. These results should be interpreted with caution due to limitations related to heterogeneity among the studies. Further high-level RCTs with larger sample sizes are necessary to establish a robust consensus., Competing Interests: Declaration of Conflicting Interests The authors have no potential conflict of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Increasing incidence of fragility fractures has spurred development of protocols, largely focused on peri-operative care, with numerous proven benefits. The purpose of this investigation was to evaluate outcomes of our hip fracture treatment program regarding successful protocol implementation, compliance, effect on subsequent fracture rates, and mortality during the first decade of adoption., Methods: A retrospective review identified patients >65 years old with fragility hip fractures between 2010 and 2022. The HiROC (+) cohort consisted of patients who received a "High-Risk Osteoporosis Clinic" (HiROC) referral for bone health evaluation and bisphosphonate initiation as indicated. Additional fracture rates and mortality at 3 years were calculated. Protocol implementation and compliance over the first 10 years was analyzed in the four identified cohorts., Results: A total of 1671 fragility hip fractures were identified, with 386 excluded due to insufficient follow-up, with an average age of 81.6 years and a median follow-up of 36.4 months. Of the 1280 included cases, 56% (n = 717) had a HiROC referral placed. HiROC(+) groups had lower subsequent fracture rates at two years, compared to those without referral (28% vs 13%, P < 0.0001) and those completing more steps of the protocol had lower subsequent fracture rates (28% vs 15% vs 13% vs 5%, P < 0.0001). No statistically significant difference was observed between the cohorts for anatomic site of subsequent fractures., Discussion: Greater than half of all eligible patients were successfully captured by the protocol. Patients completing more steps of the protocol had lower subsequent fracture rates. Captured patients demonstrated reduced mortality rates when compared to current literature., Conclusion: Successful implementation of this geriatric hip fracture protocol was associated with reduced additional fractures and mortality rates. Identifying steps of process failures in the protocol can provide opportunities for increased compliance and reduction in future fracture occurrences., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2024.)

Medical school curriculums have increasingly shifted to an integrated curriculum and have been replacing lecture with 'flipped classroom' approaches. Analyses of the benefits of the integrated curriculum and flipped classroom model typically report enhanced student performance. However, the question is whether institutional self-evaluation of curricular success is biased to demonstrate success that may not objectively exist and/or whether such biased data are presented during Liaison Committee on Medical Education (LCME) site visits. An objective determination of curricular effectiveness requires an absence of bias and of efforts to put an institutional 'thumb on the scale' to obtain desired results. In addition, bias may exist in the rationale for implementing these curricular changes in the first place; these can include, for example, with respect to career advancement as well as ideological motivation. Thus, in this paper I examine potential problems with institutional bias with evaluation of curriculum and how to overcome these.

Objective: We hypothesized that the administration of amantadine would increase awakening of comatose patients resuscitated from cardiac arrest., Methods: We performed a prospective, randomized, controlled pilot trial, randomizing subjects to amantadine 100 mg twice daily or placebo for up to 7 days. The study drug was administered between 72 and 120 hours after resuscitation and patients with absent N20 cortical responses, early cerebral edema, or ongoing malignant electroencephalography patterns were excluded. Our primary outcome was awakening, defined as following two-step commands, within 28 days of cardiac arrest. Secondary outcomes included length of stay, awakening, time to awakening, and neurologic outcome measured by Cerebral Performance Category at hospital discharge. We compared the proportion of subjects awakening and hospital survival using Fisher exact tests and time to awakening and hospital length of stay using Wilcoxon rank sum tests., Results: After 2 years, we stopped the study due to slow enrollment and lapse of funding. We enrolled 14 subjects (12% of goal enrollment), seven in the amantadine group and seven in the placebo group. The proportion of patients who awakened within 28 days after cardiac arrest did not differ between amantadine (n=2, 28.6%) and placebo groups (n=3, 42.9%; P>0.99). There were no differences in secondary outcomes. Study medication was stopped in three subjects (21.4%). Adverse events included a recurrence of seizures (n=2; 14.3%), both of which occurred in the placebo group., Conclusion: We could not determine the effect of amantadine on awakening in comatose survivors of cardiac arrest due to small sample size.

Background: Patients with aneurysmal subarachnoid hemorrhage (aSAH) who survive the rupture are at risk for delayed neurologic deficits and cerebral infarction. The ideal method(s) of surveillance for cerebral vasospasm, and the link between radiographic vasospasm and delayed neurologic deficits, remain controversial. We instituted a postbleed day 7 angiography protocol with the stated goals of identification of vasospasm, improving neurologic outcomes, and possibly lowering cost of care., Methods: We conducted a quality improvement project in which we retrospectively analyzed consecutive cases of aSAH from a single institution over a 5-year period. Patients were excluded if they did not receive treatment for their aneurysm or were < 18 years of age. We analyzed demographic and outcome information for patients managed by protocolled angiography versus those who were managed by as-needed endovascular rescue therapy. Statistical tests were performed comparing means and proportions in both cohorts, as appropriate., Results: In total, 223 patients were identified who met inclusion criteria. In total, 157 patients were identified in the protocolled day 7 angiography group, and 66 were in the nonprotocolled angiography group. Demographics were similar between the day 7 angiogram and medical management cohorts, except for a higher mean age among the latter group (p = 0.016). The protocolled angiography group underwent a significantly greater number of angiograms (p < 0.001) and had a significantly higher cost of hospitalization ($240,327 vs. $205,719, p = 0.03), with no significant difference in rate of cerebral infarction, length of intensive care unit stay, length of hospital stay, discharge location, or discharge modified Rankin Score., Conclusions: This cohort comparison analysis draws into question the practice of protocolized cerebral angiography in patients with aSAH., (© 2023.

Purpose: This study employs both the fragility index (FI) and fragility quotient (FQ) to assess the level of robustness in the cervical disc arthroplasty (CDA) literature. We hypothesize that dichotomous outcomes involving CDA would exhibit statistical vulnerability., Methods: A PubMed search was conducted to evaluate dichotomous data for randomized controlled trials (RCTs) in CDA literature from 2000 to 2023. The FI of each outcome was calculated through the reversal of a single outcome event until significance was reversed. The FQ was calculated by dividing each fragility index by the study sample size. The interquartile range (IQR) was also calculated for the FI and FQ., Results: Of the 1561 articles screened, 111 met the search criteria, with 35 RCTs evaluating CDA included for analysis. Six hundred and ninety-three outcome events with 130 significant (P < 0.05) outcomes and 563 nonsignificant (P ≥ 0.05) outcomes were identified. The overall FI and FQ for all 693 outcomes were 5 (IQR 3-7) and 0.019 (IQR 0.011-0.043). Fragility analysis of statistically significant outcomes and nonsignificant outcomes both revealed an FI of 5. All of the studies reported loss to follow-up (LTF) data where 65.7% (23) did not report or reported an LTF greater or equal to 5., Conclusions: The literature regarding CDA RCTs lacks statistical robustness and may misrepresent the conclusions with the sole use of the P value. By implementing the FI and FQ along with the P value, we believe the interpretation and contextualization of the clinical data surrounding CDA will be better understood., (© 2024. The Author(s).)

Background: Obesity is a well-established risk factor of renal cell carcinoma (RCC), however the impact of obesity on surgical outcomes for racial and ethnic minority patients with RCC is unclear. This study investigated whether a higher body mass index (BMI) or obesity (BMI ≥30 kg/m 2 ) was associated with worse perioperative outcomes and if there were heterogeneous effects based on race, ethnicity, and neighborhood-level socioeconomic factor., Methods: In this single-center cross-sectional study, medical records of patients who underwent partial or radical nephrectomy between 2010 and 2022 were retrospectively reviewed. Logistic regression analysis was performed to assess associations of BMI and perioperative outcomes [ischemia time, estimated blood loss (EBL), and length of hospital stay]., Results: A total of 432 patients, including 49.8% non-Hispanic White (NHW), 35.0% Hispanic, and 6.9% American Indian (AI) patients, were included. Median [interquartile range (IQR)] BMI was 30.2 (26.3-35.2) kg/m 2 , and Hispanic (31.5) and AI (32.5) patients had higher median BMI than NHW (29.1) patients (P=0.006). Median ischemia time, EBL, and length of hospital stay were 18.5 (IQR, 15.0-22.4) minutes, 150 (IQR, 75.0-300.0) mL, and 3 (IQR, 2-5) days. BMI ≥35 kg/m 2 was associated with a longer ischemia time [>18.5 minutes; odds ratio (OR), 5.17; 95% confidence interval (CI): 1.81-14.76; P=0.002], and the association was stronger in NHW than Hispanic patients (BMI continuous OR, 1.13; 95% CI: 1.04-1.22; P=0.004 in NHW and OR, 1.07; 95% CI: 0.98-1.17; P=0.12 in Hispanics). Class I and II/III obese patients had over two-fold increased odds of a larger EBL (>150 mL) than patients with normal weight (OR, 2.17; 95% CI: 1.03-4.59; P=0.04 for class I and OR, 2.24; 95% CI: 1.04-4.84; P=0.04 for class II/III obese patients). This association was stronger in patients from neighborhoods with high social deprivation index (SDI) and in NHW patients (BMI ≥30 vs. <30 kg/m 2 , OR, 3.53; 95% CI: 1.57-7.97; P=0.002 in high SDI neighborhoods and OR, 2.38; 95% CI: 1.10-5.14; P=0.03 in NHW). BMI was not associated with a longer hospital stay., Conclusions: In this study, obesity increased likelihood of worse perioperative outcomes, and the associations varied based on race and ethnicity and neighborhood-level socioeconomic factors., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at https://tau.amegroups.com/article/view/10.21037/tau-23-421/coif).

Purpose: Proximity to critical neurovascular structures can create significant obstacles during surgical resection of foramen magnum meningiomas (FMMs) to the detriment of treatment outcomes. We propose a new classification that defines the tumor's relationship to neurovascular structures and assess correlation with postoperative outcomes., Methods: In this retrospective review, 41 consecutive patients underwent primary resection of FMMs through a far lateral approach. Groups defined based on tumor-neurovascular bundle configuration included Type 1, bundle ventral to tumor; Type 2a-c, bundle superior, inferior, or splayed, respectively; Type 3, bundle dorsal; and Type 4, nerves and/or vertebral artery encased by tumor., Results: The 41 patients (range 29-81 years old) had maximal tumor diameter averaging 30.1 mm (range 12.7-56 mm). Preoperatively, 17 (41%) patients had cranial nerve (CN) dysfunction, 12 (29%) had motor weakness and/or myelopathy, and 9 (22%) had sensory deficits. Tumor type was relevant to surgical outcomes: specifically, Type 4 demonstrated lower rates of gross total resection (65%) and worse immediate postoperative CN outcomes. Long-term findings showed Types 2, 3, and 4 demonstrated higher rates of permanent cranial neuropathy. Although patients with Type 4 tumors had overall higher ICU and hospital length of stay, there was no difference in tumor configuration and rates of postoperative complications or 30-day readmission., Conclusion: The four main types of FMMs in this proposed classification reflected a gradual increase in surgical difficulty and worse outcomes. Further studies are warranted in larger cohorts to confirm its reliability in predicting postoperative outcomes and possibly directing management decisions., (© 2024.

Teams and the promotion of teamwork for both faculty and for students can be key components of integrated curriculum and 'flipped classroom' active learning approaches for medical education. The benefits of teams and teamwork are presented to faculty and students, sometimes via indoctrination, but the costs of the team approach, balanced against the purported benefits, are typically not discussed. This unbalanced presentation creates the need for a statement of a contrarian view. I posit that among the problems of teams and teamwork in education are diminishment of individual initiative and individual responsibility, lowering standards to the least common denominator, creating excess obligations with respect toward weaker team members, negative effects on academic freedom, inconsistency with respect to how faculty and students are evaluated, and giving students a somewhat false view of their accountability as a medical professional. Possible ideological considerations and attitudes toward individualism with respect to teams need to be understood as well.

Reoperative vascular ring surgery is uncommon. Standard redo ipsilateral thoracotomy may present technical challenges and risks. We describe a patient with right aortic arch, aberrant left subclavian artery, and a Kommerell diverticulum in whom previous vascular ring division via left thoracotomy did not relieve dysphagia. Three years after the unsuccessful operation, left subclavian-carotid transposition via supraclavicular incision followed by resection of the Kommerell diverticulum via right thoracotomy with extracorporeal circulation relieved symptoms. Contralateral thoracotomy with extracorporeal circulation provides a safe, alternative approach to redo ipsilateral thoracotomy for resection of a symptomatic Kommerell diverticulum. We review the literature on the incidence, surgical indications, and operative approaches to manage symptoms from a Kommerell diverticulum., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Introduction: Pennsylvania opened its first medical marijuana (MMJ) dispensary in 2018. Qualifying conditions include six conditions determined to have no or insufficient evidence to support or refute MMJ effectiveness. We conducted a study to describe MMJ dispensary access in Pennsylvania and to determine whether dispensary proximity was associated with MMJ certifications and community demographics., Methods: Using data from the Pennsylvania Department of Health, we geocoded MMJ dispensary locations and linked them to US Census Bureau data. We created dispensary access measures from the population-weighted centroid of Zip Code Tabulation Areas (ZCTAs): distance to nearest dispensary and density of dispensaries within a 15-min drive. We evaluated associations between dispensary access and the proportion of adults who received MMJ certification and the proportion of certifications for low evidence conditions (amyotrophic lateral sclerosis, epilepsy, glaucoma, Huntington's disease, opioid use disorder, and Parkinson's disease) using negative binomial modeling, adjusting for community features. To evaluate associations racial and ethnic composition of communities and distance to nearest dispensary, we used logistic regression to estimate the odds ratios (OR) and 95% confidence intervals (CI), adjusting for median income., Results: Distance and density of MMJ dispensaries were associated with the proportion of the ZCTA population certified and the proportion of certifications for insufficient evidence conditions. Compared to ZCTAs with no dispensary within 15 min, the proportion of adults certified increased by up to 31% and the proportion of certifications for insufficient evidence decreased by up to 22% for ZCTAs with two dispensaries. From 2018 to 2021, the odds of being within five miles of a dispensary was up to 20 times higher in ZCTAs with the highest proportions of individuals who were not White (2019: OR: 20.14, CI: 10.7-37.8) and more than double in ZCTAs with the highest proportion of Hispanic individuals (2018: OR: 2.81, CI: 1.51-5.24), compared to ZCTAs with the lowest proportions., Conclusions: Greater dispensary access was associated with the proportions of certified residents and certifications for low evidence conditions. Whether these patterns are due to differences in accessibility or demand is unknown. Associations between community demographics and dispensary proximity may indicate MMJ access differences., Competing Interests: The authors have no conflicts of interest to declare., (© 2024 The Author(s).

Background: Lymphedema (LE) is the most notable complication of axillary surgery. The axillary reverse mapping (ARM) technique was created to decrease LE. This study aims to evaluate a single surgeon's experience with ARM in patients undergoing sentinel lymph node biopsy (SLNB) or axillary lymph node dissection (ALND) for breast cancer., Methods: We retrospectively analyzed patients who underwent SLNB or ALND. Tumor characteristics and treatments received were evaluated. Surgical intervention and use of ARM were compared to assess LE rates. A subgroup analysis was also performed of patients who underwent NAC., Results: LE was initially reported in 7.1% (n = 10) of patients; 3.3% (n = 4) with SLNB and 35% (n = 6) with ALND. At initial follow-up, LE was reported 16.4% more often in patients who underwent ALND with no ARM, and 38.8% more often in patients who underwent ALND plus ARM. An increased risk of LE was found in patients treated with ALND (OR = 16.0, P < .001). All patients who underwent ARM were 12.75% more likely to develop LE if they received NAC ( P < .05). Patients in the ALND group who also received NAC were more likely to undergo ARM as compared with patients in the SLNB group ( P < .01)., Discussion: Our study showed that ARM failed to decrease the incidence of LE. Until better surgical outcomes are shown for the prevention of LE using ARM, other approaches should be utilized. However, larger prospective studies are needed to evaluate ARM., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: We used a high-throughput assay of 5000 plasma proteins to identify biomarkers associated with periodic limb movements (PLM) and restless legs syndrome (RLS) in adults., Methods: Participants (n = 1410) of the Stanford Technology Analytics and Genomics in Sleep (STAGES) study had blood collected, completed a sleep questionnaire, and underwent overnight polysomnography with the scoring of PLMs. An aptamer-based array (SomaScan) was used to quantify 5000 proteins in plasma. A second cohort (n = 697) that had serum assayed using a previous iteration of SomaScan (1300 proteins) was used for replication and in a combined analysis (n = 2107). A 5% false discovery rate was used to assess significance., Results: Multivariate analyses in STAGES identified 68 proteins associated with the PLM index after correction for multiple testing (ie, base model). Most significantly decreased proteins were iron-related and included Hepcidin (LEAP-1), Ferritin, and Ferritin light chain. Most significantly increased proteins included RANTES, Cathepsin A, and SULT 1A3. Of 68 proteins significant in the base model, 17 were present in the 1300 panel, and 15 of 17 were replicated. The most significant proteins in the combined model were Hepcidin (LEAP-1), Cathepsin A, Ferritin, and RANTES. Exploration of proteins in RLS versus non-RLS identified Cathepsin Z, Heme oxygenase 2 (HO-2), Interleukin-17A (upregulated in the combined cohort), and Megalin (upregulated in STAGES only) although results were less significant than for proteins associated with PLM index., Conclusions: These results confirm the association of PLM with low iron status and suggest the involvement of catabolic enzymes in PLM/RLS., (Copyright © 2024 National Sleep Foundation.

Study Design: Retrospective chart review., Objectives: Lumbar interbody fusion (LIF) can be achieved with various techniques. Evidence supporting the long-term clinical advantages of one technique over another are inconclusive. The purpose of this study was to (1) determine the changes in sagittal parameters in the preoperative, intraoperative, and post-operative phase, (2) evaluate the radiographic maintenance of these parameters over time, and (3) compare the demographics and patient reported outcomes of patients undergoing various LIF techniques., Methods: We performed a retrospective chart review of patients with degenerative spine disease undergoing single level anterior (ALIF), lateral (LLIF), posterior (PLIF), or transforaminal (TLIF) lumbar interbody fusion. Data collected included patient demographics and diagnosis at time of surgery. Upright lumbar radiographs taken pre-operatively, intra-operatively, and post-operatively were measured for lumbar lordosis (LL), segmental lordosis (SL), posterior disc height (PDH), and foraminal height (FH)., Results: 194 patients in a single center were included. PDH and FH increased intra-operatively following ALIF ( P < .0001), PLIF ( P < .0001), LLIF ( P < .0001), and TLIF ( P < .0001). SL also increased intra-operatively for ALIF ( P = .002) and LLIF ( P = .0007). Compared to intra-operative radiographs, PDH and FH decreased at latest post-operative phase for ALIF ( P < .03), LLIF ( P < .003), TLIF ( P < .001), and PLIF ( P < .005). SL decreased for ALIF ( P = .0008), and TLIF ( P = .02). LL did not change postoperatively across techniques. Patient reported outcomes improved post-surgically and disability index decreased, but neither differed between techniques., Conclusion: LIF, regardless of technique, was shown to provide significant radiographic changes in PDH and FH. Techniques utilizing larger intervertebral cage sizes (ALIF/LLIF) improved SL. Single level LIF did not affect overall LL. No single technique displayed superior radiographic robustness over time., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background/aims: Primary simultaneous bilateral total joint arthroplasty (simBTJA) can cause postoperative anemia. Clinicians might hesitate to discharge patients who have large changes in hemoglobin [Hgb], despite Hgb levels remaining above transfusion thresholds. This study was conducted to evaluate if delta Hgb or perioperative blood loss correspond with readmission in primary simBTJA patients not transfused perioperatively., Methods: From 2015 - 2020, a retrospective chart review of primary simultaneous bilateral total hip/knee arthroplasty cases was conducted. Preoperative and postoperative Hgb levels were obtained from our database or chart review. Exclusion criteria comprised patients who had a preoperative transfusion or transfusion postoperatively during their surgical admission, and patients not discharged home. Outcomes included whether delta Hgb or perioperative blood loss were predictive of 90-day readmission postoperatively, postoperative anemia, and transfusion during readmission., Results: The 510 individuals undergoing primary simBTJA possessed an average preoperative Hgb of 14.1 g/dL, starting blood volume of 5012 mL, postoperative Hgb of 10.0 g/dL, delta Hgb of 3.90 g/dL, and perioperative blood loss of 1403 mL. 19 patients (3.73 %) were readmitted, with none requiring transfusion. When constructing receiver operating characteristic (ROC) curves predicting readmission from delta Hgb, a threshold of 4.1 g/dL had an area under the curve (AUC) of 0.454, a sensitivity of 0.473, and a specificity of 0.56. For ROC curves predicting readmission from perioperative blood loss, a threshold of 1144 mL had an AUC of 0.453, a sensitivity of 0.842, and a specificity of 0.297. Similar AUCs, sensitivities, and specificities were obtained when adjusting ROC curves for preoperative Hgb or starting blood volume., Conclusions: Delta Hgb and perioperative blood loss do not predict 90-day readmission after primary simBTJA in patients not transfused perioperatively. Patients with a large delta Hgb but stay higher than a 7 g/dL restrictive transfusion threshold may have a strong capacity to overcome postoperative anemia., Competing Interests: 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., (© 2024.)

The side effects of cancer therapy continue to cause significant health and cost burden to the patient, their friends and family, and governments. A major barrier in the way in which these side effects are managed is the highly siloed mentality that results in a fragmented approach to symptom control. Increasingly, it is appreciated that many symptoms are manifestations of common underlying pathobiology, with changes in the gastrointestinal environment a key driver for many symptom sequelae. Breakdown of the mucosal barrier (mucositis) is a common and early side effect of many anti-cancer agents, known to contribute (in part) to a range of highly burdensome symptoms such as diarrhoea, nausea, vomiting, infection, malnutrition, fatigue, depression, and insomnia. Here, we outline a rationale for how, based on its already documented effects on the gastrointestinal microenvironment, medicinal cannabis could be used to control mucositis and prevent the constellation of symptoms with which it is associated. We will provide a brief update on the current state of evidence on medicinal cannabis in cancer care and outline the potential benefits (and challenges) of using medicinal cannabis during active cancer therapy., (© 2023.

Ketamine and esketamine are efficacious for treatment-resistant depression. Unlike other antidepressants, ketamine lacks a therapeutic delay and decreases the risk for suicide. This cross-sectional study geographically characterized ketamine and esketamine prescribing to United States (US) Medicaid patients. Ketamine and esketamine prescription rates and spending per state were obtained. Between 2009 and 2020, ketamine prescribing rates peaked in 2013 followed by a general decline. For ketamine and esketamine in 2019, Montana (967/million enrollees) and Indiana (425) showed significantly higher prescription rates, respectively, relative to the national average. A total of 21 states prescribed neither ketamine nor esketamine in 2019. There was a 121.3% increase in esketamine prescriptions from 2019 to 2020. North Dakota (1,423) and North Carolina (1,094) were significantly elevated relative to the average state for esketamine in 2020. Ten states prescribed neither ketamine nor esketamine in 2020. Medicaid programs in 2020 spent 72.7-fold more for esketamine ($25.3 million) than on ketamine (0.3 million). Despite the effectiveness of ketamine and esketamine for treatment-resistant depression and anti-suicidal properties, their use among Medicaid patients was limited and highly variable in many areas of the US. Further research to better understand the origins of this state-level variation is needed.

Introduction: The purpose of this study was to utilize the fragility index to assess the robustness of randomized controlled trials (RCTs) evaluating the management of calcaneus fractures. We hypothesize that the dichotomous outcomes in calcaneus fracture literature will be statistically fragile and comparable to other orthopedic specialties., Methods: We performed a PubMed search for calcaneus fracture RCTs from 2000 to 2022 using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The fragility index (FI) of each outcome was calculated through the reversal of a single outcome event until significance was reversed. The fragility quotient (FQ) was calculated by dividing each fragility index by study sample size. The interquartile range (IQR) was also calculated for the FI and FQ., Results: Of the 3003 studies screened, 97 met the search criteria, with 19 RCTs evaluating calcaneus fractures included in the analysis. Seventy-nine dichotomous outcomes with 30 significant (P < 0.05) outcomes and 49 with nonsignificant (P> 0.05) outcomes were identified. The overall FI and FQ of all outcomes were 6 (IQR 3-8) and 0.067 (IQR 0.032-0.100), respectively., Conclusions: The literature surrounding calcaneus fractures may not be as statistically stable as previously thought. The sole reliance on the P value may depict misleading results. We, therefore, recommend reporting the P value in conjunction with the FI and FQ to give a robust contextualization of clinical findings in the calcaneus fracture literature., Competing Interests: Declaration of Competing Interest The authors did not receive support from any organization for the submitted work.

Objective: Chronic pain is a major problem for patients with Charcot-Marie-Tooth (CMT) disease. This exploratory study examined patient reported efficacy of medical cannabis for pain management in this population. Methods: Participants (N = 56; 71.4% female; Age = 48.9, SD = 14.6; 48.5% CMT1) were recruited though the Hereditary Neuropathy Foundation. The online survey contained 52 multiple choice questions about demographics, medical cannabis use, symptomology, efficacy, and adverse effects. Results: Nearly all (90.9%) of respondents reported experiencing pain, including all (100%) females and 72.7% of males (chi-square P < .05) with 91.7% of respondents indicating cannabis provided at least 50% pain relief. The most frequent response was an 80% reduction in pain. Moreover, 80.0% of respondents reported using less opiates, 69% noted using less sleep medication, and 50.0% reported using less anxiety/antidepressant medications. Negative side effects were noted by 23.5% of respondents. However, almost all (91.7%) of that subgroup did not have plans to stop consuming cannabis. One-third (33.9%) possessed a medical cannabis certificate. Patient perceptions of their physicians' attitudes regarding patient medical cannabis use greatly impacted whether respondents informed their providers of their usage. Conclusion: The vast majority of patients with CMT reported that cannabis was effective to manage pain symptoms. These data support the need for prospective, randomized, controlled trials using standardized dosing protocols to further delineate and optimize the potential use of cannabis to treat pain related to CMT., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Metformin is among the most widely used antidiabetic drugs. Studies over the past few years have identified multiple novel molecular targets and pathways that metformin acts on to exert its beneficial effects in treating type 2 diabetes as well as other disorders involving dysregulated inflammation and redox homeostasis. In this mini-review, we discuss the latest cutting-edge research discoveries on novel molecular targets of metformin in glycemic control, cardiovascular protection, cancer intervention, anti-inflammation, antiaging, and weight control. Identification of these novel targets and pathways not only deepens our understanding of the molecular mechanisms by which metformin exerts diverse beneficial biological effects, but also provides opportunities for developing new mechanistically based drugs for human diseases., (© 2023.

Objective: The objectives of this report were to characterize the regional and state differences in prescription methamphetamine and amphetamine distribution in the US., Methods: Prescription methamphetamine and amphetamine distribution was obtained from the Drug Enforcement Administration for 2019., Results: Total per capita drug weight distribution of amphetamine was 4,000 times higher than methamphetamine. Regionally, total per capita drug weight for methamphetamine was highest in the West (32.2% of total distribution) and lowest in the Northeast (17.4%). The total per capita drug weight for amphetamine was highest in the South (37.0% of total distribution) and lowest in the Northeast (19.4%). Distribution of methamphetamine was 16.1% while amphetamine was 54.0% of its production quota., Conclusion: Overall, prescription amphetamine distribution was common while prescription methamphetamine distribution was rare. The patterns observed in distribution are likely the result of stigmatization, differences in accessibility, and the efforts of initiatives such as the Montana Meth Project.

Candidate gene studies have identified genetic variants associated with clinical outcomes following aneurysmal subarachnoid haemorrhage (aSAH), but no genome-wide association studies have been performed to date. Here we report the results of the discovery phase of a two-stage genome-wide meta-analysis of outcome after aSAH. We identified 157 independent loci harbouring 756 genetic variants associated with outcome after aSAH (p < 1 × 10 -4 ), which require validation. A single variant (rs12949158), in SPNS2, achieved genome-wide significance (p = 4.29 × 10 -8 ) implicating sphingosine-1-phosphate signalling in outcome after aSAH. A large multicentre international effort to recruit samples for validation is required and ongoing. Validation of these findings will provide significant insight into the pathophysiology of outcomes after aSAH with potential implications for treatment., (© 2022. The Author(s).)

Background: Patients undergoing total joint arthroplasty (TJA) are at increased risk for venous thromboembolism (VTE). Prediction tools such as the Caprini Risk Assessment Model (RAM) have been developed to identify patients at higher risk. However, studies have reported heterogeneous results when assessing its efficacy for TJA. Patients treated in an urban health safety net hospital have increased medical complexity, advanced degenerative joint disease, and severe disability prior to TJA increasing the risk of VTE. We hypothesize that use of a tool designed to account for these conditions-the Boston Medical Center (BMC) VTE score-will more accurately predict VTE in this patient population., Methods: A retrospective case-control study was performed including subjects 18 years of age and older who underwent primary or revision TJA in an urban academic health safety net hospital. Patients with hemiarthroplasties, simultaneous bilateral TJA, and TJA after acute trauma were excluded. A total of 80 subjects were included: 40 who developed VTE after TJA (VTE+) and 40 who did not develop VTE (controls). Subjects were matched by age, gender, and surgical procedure., Results: There was a statistically significant difference between the mean BMC VTE score for VTE+ and controls (4.40 and 3.13, respectively, P = .036). Conversely, there was no statistical difference between the mean Caprini scores for VTE+ and controls (9.50 and 9.35, respectively, P = .797)., Conclusions: In a health safety-net patient population, an institutional RAM-the BMC VTE score-was found to be more predictive of VTE than the modified Caprini RAM following TJA. The BMC-VTE score should be externally validated to confirm its reliability in VTE prediction in similar patient populations.

Background: Z-drugs are nonbenzodiazepine hypnotics used for sleep initiation and maintenance; these drugs increase the risk of fall-related injuries in older adults. The American Geriatrics Society's Beers criteria classifies Z-drugs as high-risk and strongly recommends avoiding prescribing Z-drugs to older adults due to adverse effects. The study objectives were to determine the prevalence of Z-drug prescribing among Medicare Part D patients and identify state or specialty-dependent prescribing differences. This study also aimed to determine prescribing patterns of Z-drugs to Medicare patients., Methods: Z-drug prescription data was extracted from the Centers for Medicare and Medicaid Services State Drug Utilization Data for 2018. For all 50 states, the number of prescriptions per 100 Medicare enrollees and days-supply per prescription was determined. The percentage of total prescriptions prescribed by each specialty and the average number of prescriptions per provider within each specialty was also determined., Results: Zolpidem was the most prescribed Z-drug (95.0%). Prescriptions per 100 enrollees were significantly high in Utah (28.2) and Arkansas (26.7) and significantly low in Hawaii (9.3) relative to the national average (17.5). Family medicine (32.1%), internal medicine (31.4%), and psychiatry (11.7%) made up the largest percentages of total prescriptions. The number of prescriptions per provider was significantly high among psychiatrists., Discussion: Contrary to the Beers criteria, Z-drugs are prescribed to older adults at high rates., Competing Interests: BJP was part of an osteoarthritis research team from 2019–2021 supported by Pfizer and Eli Lilly.

The number of primary care physicians in the United States is inadequate to meet current or projected needs. This is likely exacerbated by continuing increases in the cost of medical education and student debt. The Geisinger Commonwealth School of Medicine is part of an integrated care delivery system in which primary care is central to managing health, improving access, and advancing value-based care. The need for primary care providers and psychiatrists is difficult to meet despite generous recruiting incentives. To address this, the Abigail Geisinger Scholars Program (AGSP) represents a novel curricular approach linked with the provision of full tuition and fees and a living stipend to students who commit to work at Geisinger in primary care or psychiatry following residency. The support is provided as a forgivable loan. The program features preferential clinical placements, curricular enhancements, and celebration of the dedicated cohort. Fair and nonpunitive provisions allow students to opt-out. The AGSP supports 45 students in each class of 115. Outcomes monitored include withdrawals from the AGSP; academic performance of participants and their satisfaction with the program; the number who choose to repay the loan rather than fulfill the service obligation; the percentage who remain at Geisinger and in primary care following the period of obligation; and other measures. This model offers an attractive opportunity for students to experience a curriculum enhanced in primary care while receiving generous financing for their medical education. It bolsters the primary care physician workforce and aligns care delivery with new financing models., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© The Author(s) 2023.)

Introduction: Dronabinol is approved in the USA for chemotherapy-induced nausea as well as vomiting and HIV-induced anorexia, while cannabidiol is primarily approved for childhood epileptic disorders Lennox-Gastaut and Dravet syndrome. The use pattern for these prescription cannabinoids in the USA is unknown. This study examined Medicaid claims for two FDA-approved prescription cannabinoids, dronabinol and cannabidiol, approved in 1985 and 2018, respectively, from 2016-2020 to better understand the pharmacoepidemiologic trends and distribution of these drugs in US Medicaid amidst the increasing use of non-pharmaceutical formulations of cannabis., Methods: The longitudinal study analyzed Medicaid prescription claims that were calculated by extracting the prescriptions on a state level from 2016 to 2020 for two cannabinoids, dronabinol and cannabidiol, where outcomes over each year were calculated. Outcomes were (1) the number of prescriptions for each state corrected for the number of Medicaid enrollees and (2) dronabinol and cannabidiol spending. Spending refers to the amount reimbursed by the state Medicaid program., Results: Dronabinol prescriptions per state decreased by 25.3% from 2016 to 2020, while cannabidiol prescriptions increased by 16,272.99% from 2018 to 2020. The spending on these drugs parallels that of their prescription trend with a 66.3% decrease in reimbursement for dronabinol ($5.7 million in 2020), whereas cannabidiol increased by +26,582.0% ($233.3 million in 2020). Dronabinol prescriptions, when corrected for the number of enrollees, in Connecticut were 136.4 times larger than in New Mexico, and seventeen states had zero prescriptions. Idaho's prescriptions of cannabidiol (27.8/10,000 enrollees) were significantly elevated relative to the national average and were 15.4-fold higher than Washington, DC (1.8/10K enrollees)., Conclusions: The prescriptions of pharmaceutical-grade tetrahydrocannabinol decreased while those of cannabidiol increased. This study also identified pronounced state-level variation in cannabinoid prescribing to Medicaid patients. State formularies and prescription drug list variation may contribute to the drug reimbursements in Medicaid, though further research is needed to identify the health policy or pharmacoeconomic origins of these disparities., Competing Interests: BJP was part of an osteoarthritis research team (2019–2021) supported by Pfizer and Eli Lilly.

Purpose of Review: This report will review existing literature on weight loss outcomes for various anti-obesity medications (AOMs) as well as their effects on human fertility, pregnancy, or breastfeeding., Recent Findings: There is a paucity of research on the effects of AOMs on human pregnancy and fertility. The majority of AOMs are not recommended during pregnancy and breastfeeding due to known or unclear risks of harm to offspring., Summary: As the prevalence of obesity rises, AOMs have proven to be effective tools for weight loss in the general adult population. When prescribing AOMs to reproductive-aged women, providers should consider both the cardiometabolic benefits of these medications and potential effects that AOMs might have on hormonal contraception, pregnancy, or breastfeeding. Animal studies in rats, rabbits, and monkeys have suggested teratogenic effects of several medications discussed in this report. However, a lack of data on the use of many AOMs during human pregnancy or lactation makes it difficult to comment on the safety of their use in these time periods. Some AOMs show promise in promoting fertility while others might decrease the efficacy of oral contraceptives, highlighting some of the special considerations that must be taken when prescribing AOMs to reproductive-aged women. More research into the risks and benefits of AOMs in the context of reproductive-aged women's unique healthcare needs is an important step in improving this population's access to effective treatments for obesity., Competing Interests: Conflict of Interest The authors don’t have any conflict of interest.

Objectives: The purpose of this longitudinal study was to describe the temporal pattern of morphine distribution nationally and between states., Methods: Drug weight was obtained from Report 5 of the US Drug Enforcement Administration's Automation of Reports and Consolidated Orders System (ARCOS) to characterize patterns in the distribution of morphine from 2012 to 2021. Morphine distribution amounts were separated by state and business type and corrected for population. States outside a 95% confidence interval relative to the national average were considered statistically significant., Key Findings: In 2012, there was a 4.6-fold difference in morphine distribution between the highest-prescribing state, Tennessee (180.2 mg/person), and the lowest-prescribing state, Texas (39.4 mg/person). By the end of 2021, national distribution of morphine had decreased by 59.9% when compared to the peak year 2012. In 2021, Tennessee (51.1 mg/person) remained the highest-prescribing state with a 3.0-fold difference relative to Texas (17.2 mg/person). The average hospital decrease (-73.9%) from 2012 to 2021 was larger than that of pharmacies (-58.2%)., Conclusions: The national 59.9% decline in morphine in the last decade may be attributable to prioritization of the US opioid crisis as a public concern. Further research is necessary to understand the persistent regional difference between states., Competing Interests: Declaration of competing interest BJP was part of an osteoarthritis research team supported by Pfizer and Eli Lilly from 2019 to 2021.

Introduction: Neurosurgeons must master microanatomy and its variants that occur at the skull base. To the best of our knowledge, we describe a previously unreported dural venous sinus (DVS) within the anterior petroclinoid fold and discuss its potential surgical relevance., Methods: Fifteen latex-injected human cadaveric heads (30 sides) underwent skull base dissection using a surgical microscope. The anterior petroclinoid fold was opened in search of evidence of an embedded DVS. When identified, this sinus was documented, photographed, and measured with microcalipers., Results: An anterior petroclinoid sinus (APCS) was identified in 67% of sides. These DVSs had a mean diameter of 0.65 mm and a length ranging from 8 to 15 mm (mean: 12.5 mm). The APCS ran from the anterior aspect of the cavernous sinus, arising just lateral (60%), posterior (20%), or medial (20%) to the anterior clinoid process, to the superior petrosal sinus (65%) or the posterior aspect of the cavernous sinus (35%), at the level of the posterior clinoid process. Along the course of the APCS, the oculomotor nerve was located medially at the oculomotor porus. Although slightly more common and larger on the right side, there was no statistically significant side difference., Conclusions: An improved knowledge of variant DVSs can lower the risk of intraoperative complications and increase our understanding of the venous outflow from the cavernous sinus. Future neuroimaging techniques might also seek to identify the APCS. This is the first description of a DVS contained within the anterior petroclinoid fold., (Copyright © 2023 Elsevier Inc.

Objective: Patient-provider communication is a major barrier to care, with some providers giving their personal phone number (PPN) to patients for increased accessibility. We investigated participant utilization of provider's PPN, its effect on participant satisfaction, provider's ability to predict abuse of this practice, and evolving provider perceptions., Study Design: Prospective, randomized study., Setting: Single institution, tertiary referral center., Methods: During a 2-week period, otolaryngology patients were randomized to either receive their provider's PPN or not. Providers predicted the likelihood of abuse. All calls/texts were documented for 4 weeks. At the study's conclusion, participants were surveyed using Press Ganey metrics. Providers were surveyed before and after to assess their likelihood of providing patients with their PPN and its impact on work demands., Results: Of the 507 participants enrolled, 266 were randomized to the phone number group (+PN). Of 44 calls/texts from 24 participants, 8 were considered inappropriate. Ten participants were predicted to abuse the PPN, but only one was accurately identified. Participants in the +PN group had a greater mean composite satisfaction score than the control group (4.8 vs 4.3; Welch's t -test, P  < .0011). At the conclusion of the study, providers were more likely to share their PPN (Wilcoxon signed-rank test, P  < .0313), and their perceived impact of this practice on workload was lower (Wilcoxon signed-rank test, P  < .0469)., Conclusion: This study demonstrates low patient utilization of provider PPNs, and poor provider predictive ability of patient abuse. Receipt of provider's PPN was associated with improved patient satisfaction.

Background: The COVID-19 pandemic has disproportionately impacted Hispanics in the USA with increased rates of SARS-CoV-2 infections, hospitalizations, and deaths. The objective of this report was to characterize the demographics and beliefs of unvaccinated Hispanics to help address their concerns that lead to vaccine hesitancy., Methods: Of 1,011 potential participants from a national online panel, 22.3% (N = 225, 51.6% female, age = 40.5) met inclusion criteria of Hispanic adults and not receiving at least one dose of the COVID-19 vaccine. The 30-item survey included items about demographics, political affiliations, sources of news (e.g., Fox vs. CNN), reasons for being unvaccinated, and ratings (0 = strongly disagree, 100 = strongly agree) of 10 controversial statements regarding COVID-19., Results: Over three-fifths (62.6%) identified side effects and safety concerns, while almost one-third (30.5%) cited a lack of efficacy as their top reasons for being unvaccinated. Agreement to "The developers of the COVID-19 vaccine rushed the development and cut corners" was rated the highest (63.22) which was significantly (p < .001) higher than the other nine statements (e.g., "The COVID-19 vaccine does not work"). Many vaccine attitudes differed significantly by political party affiliation and some by gender and news source. Republicans (59.9 ± 4.2) scored higher than Democrats (38.5 ± 4.2, p ≤ .001) to "If I've already had COVID-19, I don't need the vaccine.", Conclusions: This study identified the heterogeneity in COVID-19 vaccine attitudes among Hispanics. Further research is needed to determine if the subgroups identified are differentially receptive to interventions to facilitate reconsideration of prior vaccination decisions., (© 2022. W.

Objective: Investigate the patient opinion on the use of Artificial Intelligence (AI) in Orthopaedics., Methods: 397 orthopaedic patients from a large urban academic center and a rural health system completed a 37-component survey querying patient demographics and perspectives on clinical scenarios involving AI. An average comfort score was calculated from thirteen Likert-scale questions (1, not comfortable; 10, very comfortable). Secondary outcomes requested a binary opinion on whether it is acceptable for patient healthcare data to be used to create AI (yes/no) and the impact of AI on: orthopaedic care (positive/negative); healthcare cost (increase/decrease); and their decision to refuse healthcare if cost increased (yes/no). Bivariate and multivariable analyses were employed to identify characteristics that impacted patient perspectives., Results: The average comfort score across the population was 6.4, with significant bivariate differences between age ( p  = 0.0086), gender ( p  = 0.0001), education ( p  = 0.0029), experience with AI/ML ( p  < 0.0001), survey format ( p  < 0.0001), and four binary outcomes ( p  < 0.05). When controlling for age and education, multivariable regression identified significant relationships between comfort score and experience with AI/ML ( p  = 0.0018) and each of the four binary outcomes ( p  < 0.05). In the final multivariable model gender, survey format, perceived impact of AI on orthopaedic care, and the decision to refuse care if it were to increase cost remained significantly associated with the average AI comfort score ( p  < 0.05). Additionally, patients were not comfortable undergoing surgery entirely by a robot with distant physician supervision compared to close supervision., Conclusion: The orthopaedic patient appears comfortable with AI joining the care team., Competing Interests: Conflict of interestInvestigation performed at Geisinger Community Medical Center, Scranton, Pennsylvania and The Mount Sinai Hospital, New York, New York and there are no conflicts of interest declared., (© Indian Orthopaedics Association 2023, Springer Nature or its licensor (e.g. a society or other partner) holds exclusive rights to this article under a publishing agreement with the author(s) or other rightsholder(s); author self-archiving of the accepted manuscript version of this article is solely governed by the terms of such publishing agreement and applicable law.)

Objective: The mortality rate of schizophrenia patients is higher than that of the general population; cardiovascular disease (CVD) is their leading cause of death. This issue must be studied since people with schizophrenia are disproportionately burdened with CVD. Therefore, our goal was to identify the prevalence of CVD and other comorbidities, stratified by age and gender, in patients with schizophrenia living in Puerto Rico., Methods: A retrospective, case-control, descriptive study was conducted. Subjects in this study were admitted to Dr. Federico Trilla's hospital from 2004 through 2014 for both psychiatric- and non psychiatric conditions. The sample populations were stratified by the confounding variables of tobacco use and alcohol abuse, and the resulting stratification was analyzed with the Cochran-Mantel-Haenszel method., Results: A higher frequency of CVDs was noted in the patients with schizophrenia compared to those in the control group. Although hypertension was the most frequent pathology encountered in both groups, ischemic heart disease was approximately four times more frequent in the patients with schizophrenia. CVD represented 58.4% and 52.7% in the schizophrenia and non-schizophrenia groups, respectively, although a statistically significant difference was not observed. The prevalence of malignancies in patients without schizophrenia was higher than in patients with schizophrenia. Moreover, the prevalence of asthma was 10.9% in the control group compared to 5.3% in the schizophrenia group., Conclusion: These findings should motivate a systematic approach to prioritizing the aggressive management, early diagnosis, and prevention of comorbid risk factors in patients with schizophrenia.

Background: The US opioid overdose epidemic continues to escalate. The restrictions on methadone availability including take-home dosing were loosened during the COVID-19 pandemic although there have been concerns about the high street value of diverted methadone. This report examined how fatal overdoses involving methadone have changed over the past two-decades including during the pandemic., Methods: The CDC's Wide-ranging Online Data for Epidemiologic Research (WONDER) was used to find the unintentional methadone related overdose death rate from 1999 to 2020. Unintentional methadone deaths were defined using the ICD X40-44 codes with only data for methadone (T40.3). Data from the DEA's Automation of Reports and Consolidated Orders System (ARCOS) on methadone overall use, opioid treatment programs use, and pain management use was gathered for all states for 2020 and corrected for population., Results: There have been dynamic changes over the past two-decades in methadone overdoses. Overdoses increased from 1999 (0.9/million) to 2007 (15.9) and declined until 2019 (6.5). Overdoses in 2020 (9.6) were 48.1% higher than in 2019 (t(50) = 3.05, p < .005). The state level correlations between overall methadone use (r(49) = +0.75, p < .001), and opioid treatment program use (r(49) = +0.77, p < .001) with overdoses were positive, strong, and statistically significant. However, methadone use for pain treatment was not associated with methadone overdoses (r(49) = -0.08)., Conclusions: Overdoses involving methadone significantly increased by 48.1% in 2020 relative to 2019. Policy changes that were implemented following the COVID-19 pandemic involving methadone take-homes may warrant further study before they are made permanent., Competing Interests: Declaration of Interests BJP was part of an osteoarthritis research team supported by Pfizer and Eli Lilly from 2019 to 2021.

Recent investments in built environment infrastructure to create healthy communities have highlighted the need for equity and environmental justice. Although the benefits of healthy community design (e.g., connecting transportation systems and land use changes) are well established, some reports suggest that these changes may increase property values. These increases can raise the risk of displacement for people with low incomes and/or who are from racial and ethnic minority groups, who would then miss out on benefits from changes in community design. This review scanned the literature for displacement mitigation and prevention measures, with the goal of providing a compilation of available strategies for a wide range of audiences including public health practitioners. A CDC librarian searched the Medline, EbscoHost, Scopus, and ProQuest Central databases, and we identified grey literature using Google and Google Scholar searches. The indexed literature search identified 6 articles, and the grey literature scan added 18 articles. From these 24 total articles, we identified 141 mitigation and prevention strategies for displacement and thematically characterized each by domain using an adapted existing typology. This work provides a well-categorized inventory for practitioners and sets the stage for future evaluation research on the implementation of strategies and practices to reduce displacement., (© 2022.

Dilation of the coronary sinus is often a result of excessive volume overload from congenital anomalies of systemic venous return to the heart. These abnormalities are often discovered incidentally later in life when a patient requires cardiac imaging, cardiac catheterization, or thoracic surgery. The most common abnormality is a persistent left superior vena cava. Inferior vena cava malformation is less common, yet several different anomalies can arise. The presence of persistent left superior vena cava or inferior vena cava anomalies requires further evaluation to rule out congenital heart disease in infants. Knowledge of technically challenging systemic venous anatomy is beneficial prior to procedures necessitating central venous access such as a central line, cardiac catheterization, and intracardiac device implantation. We present an unusual case of persistent LSVC and IVC both draining directly into a severely dilated coronary sinus that was diagnosed by fetal echocardiogram and later confirmed postnatally by transthoracic echocardiogram and computed tomography angiography. To our knowledge this is the second reported case of IVC drainage into the CS and the first case that reports this as a prenatal diagnosis., (© 2022.

Introduction: Lesser tuberosity osteotomy (LTO) and subscapularis peel (Peel) are 2 common techniques used to mobilize the subscapularis tendon during anatomic total shoulder arthroplasty (TSA). The literature is inconclusive over which technique is optimal; thus, controversy exists over which technique should be performed. The purpose of this study was to compare specific functional internal rotation tasks and general outcome scores in TSA patients who received either an LTO or Peel., Methods: A retrospective review of 563 patients treated with primary TSA using either an LTO (n = 358) or Peel (n = 205) with a minimum 2-year follow-up was performed. Subjective internal rotation, active internal rotation, and specific questions related to functional internal rotation isolated from the Simple Shoulder Test (SST) and American Shoulder and Elbow Surgeons functional questionnaires were reviewed. Other outcome scores including visual analog scale pain and function, Single Assessment Numerical Evaluation, SST, American Shoulder and Elbow Surgeons, and revision rates were compared between the 2 groups., Results: The study found no difference in postoperative functional internal rotation and range of motion between LTO and Peel. Patients who received a Peel were shown to have a slightly greater improvement in the ability to perform toileting and a higher average change in SST score that did not reach clinical significance. There was no difference in the percentage of maximal improvement, revision rate, or need for revision between the 2 groups., Conclusion: No difference was found between the LTO and Peel techniques in regard to functional tasks of internal rotation at short-term follow-up., (Copyright © 2022 Journal of Shoulder and Elbow Surgery Board of Trustees.
