Effect of multi-level social risk factors on developmental trajectories of sexual risk behaviors among Bahamian middle-to-late adolescents
Background: Few studies have examined how multi-level social factors interact and affect developmental patterns of sexual risk among middle-to-late adolescents who are at risk of experiencing sexual risk behaviors. We examined developmental trajectories of sexual risk behaviors of boys and girls in middle-to-late adolescence and the effects of exposure to three social risk factors (poor parental monitoring, peer risk, and neighborhood risk).
Methods: We followed 2,332 Bahamian adolescents every six months from Grades 10-12. We used group-based trajectory modeling to identify distinct trajectories of sexual risk behaviors for boys and girls.
Results: We identified three trajectories each for boys and girls. Peer risk and neighborhood risk predicted a high sexual-risk trajectory for boys, and peer risk (alone or combined with other risk factors) had the greatest impact on the membership of moderate-to-high-risk trajectory for girls. Parental monitoring had a relatively small effect on adolescents' sexual risk behavior.
Conclusion: Our results underscore the importance of early identification of adolescents with sexual risk behavior and development of targeted prevention interventions to improve adolescent health outcomes
Ultra-low-dose vs. standard-of-care-dose CT of the chest in patients with post-COVID-19 conditions-a prospective intra-patient multi-reader study
Objectives: To conduct an intrapatient comparison of ultra-low-dose computed tomography (ULDCT) and standard-of-care-dose CT (SDCT) of the chest in terms of the diagnostic accuracy of ULDCT and intrareader agreement in patients with post-COVID conditions.
Methods: We prospectively included 153 consecutive patients with post-COVID-19 conditions. All participants received an SDCT and an additional ULDCT scan of the chest. SDCTs were performed with standard imaging parameters and ULDCTs at a fixed tube voltage of 100 kVp (with tin filtration), 50 ref. mAs (dose modulation active), and iterative reconstruction algorithm level 5 of 5. All CT scans were separately evaluated by four radiologists for the presence of lung changes and their consistency with post-COVID lung abnormalities. Radiation dose parameters and the sensitivity, specificity, and accuracy of ULDCT were calculated.
Results: Of the 153 included patients (mean age 47.4 ± 15.3 years; 48.4% women), 45 (29.4%) showed post-COVID lung abnormalities. In those 45 patients, the most frequently detected CT patterns were ground-glass opacities (100.0%), reticulations (43.5%), and parenchymal bands (37.0%). The accuracy, sensitivity, and specificity of ULDCT compared to SDCT for the detection of post-COVID lung abnormalities were 92.6, 87.2, and 94.9%, respectively. The median total dose length product (DLP) of ULDCTs was less than one-tenth of the radiation dose of our SDCTs (12.6 mGy*cm [9.9; 15.5] vs. 132.1 mGy*cm [103.9; 160.2]; p < 0.001).
Conclusion: ULDCT of the chest offers high accuracy in the detection of post-COVID lung abnormalities compared to an SDCT scan at less than one-tenth the radiation dose, corresponding to only twice the dose of a standard chest radiograph in two views.
Clinical relevance statement: Ultra-low-dose CT of the chest may provide a favorable, radiation-saving alternative to standard-dose CT in the long-term follow-up of the large patient cohort of post-COVID-19 patients
Prognostic Factors in Limited-Stage Small Cell Lung Cancer: A Secondary Analysis of CALGB 30610-RTOG 0538
Importance: The impact of patient-specific, disease-related, and social factors on outcomes in limited-stage small cell lung cancer (LS-SCLC) is not well defined. A post hoc secondary analysis of such factors from the Cancer and Leukemia Group B (CALGB) 30610-Radiation Therapy Oncology Group (RTOG) 0538 trial may impact future trial design.
Objective: To assess the comprehensive demographic, disease-related, treatment-related, and social factors for potential associations with survival outcomes and understand whether specific subpopulations may benefit from radiotherapy (RT) dose escalation in LS-SCLC.
Design, setting, and participants: This post hoc secondary analysis of a randomized clinical trial included 638 adults with LS-SCLC treated at 186 unique treatment sites with at least 1 accrual for all patients from March 15, 2008, to December 1, 2019; 313 patients were randomized to receive RT twice daily to a dosage of 45 Gy for 3 weeks and 325 to receive RT once daily to a dosage of 70 Gy for 7 weeks. Data were locked February 28, 2022, and analyzed from November 28, 2022, to June 4, 2024.
Interventions: Twice-daily RT or once-daily RT.
Main outcomes and measures: Multivariable Cox proportional hazards models evaluated the association of treatment groups and other risk factors with progression-free survival (PFS) and overall survival (OS). Patient-specific factors included age, sex, and Eastern Cooperative Oncology Group performance status. Disease-related factors included tumor, nodal, and overall cancer stages. Treatment-related factors included type of chemotherapy, timing of concurrent RT, RT technique, and prophylactic cranial irradiation. Social factors included marital status and treatment center accrual volume.
Results: Among 507 patients (260 [51.3%] female and 247 [48.7%] male; mean [SD] age, 62.6 [7.9] years) included in the multivariate survival analysis, with a median follow-up of 4.7 (IQR, 3.7-7.1) years, female sex was associated with improved OS (hazard ratio [HR], 0.73 [95% CI, 0.58-0.91]; P = .006), while being 70 years or older was associated with decreased OS (HR, 1.50 [95% CI, 1.14-1.98]; P = .004). Neither age nor sex was associated with PFS. When compared with those with N1 disease, OS and PFS were worse in patients with N2 (HRs, 1.64 [95% CI, 1.19-2.26]; P = .002 and 1.36 [95% CI, 1.02-1.81]; P = .04, respectively) and N3 (HRs, 2.03 [95% CI, 1.40-2.93]; P < .001 and 1.63 [95% CI, 1.17-2.26]; P = .004) disease. Compared with stage II cancer, OS was worse for stage IIIA (HR, 1.65 [95% CI, 1.17-2.31]; P = .004) and stage IIIB (HR, 1.94 [95% CI, 1.34-2.83]; P < .001). Compared with high-volume accrual centers, treatment at low- or middle-volume accrual centers was associated with worse PFS (HRs, 1.94 [95% CI, 1.33-2.82; P < .001] and 1.44 [95% CI, 1.15-1.82; P = .002], respectively) and worse OS (HRs, 1.55 [95% CI, 1.03-2.32; P = .03] and 1.33 [95% CI, 1.04-1.70; P = .02], respectively).
Conclusions and relevance: This secondary analysis of the CALGB 30610-RTOG 0538 randomized clinical trial of patients with LS-SCLC found associations between female sex or being younger than 70 years and improved overall survival and between advanced nodal stage or treatment at low- or middle-volume accrual centers and worse outcomes. These findings suggest that stratification by nodal stage, clinical stage, and age should be considered in future randomized trials.

Possible Bupivacaine Induced Hepatitis Following Wide Awake, Local Anesthesia, No Tourniquet Carpal Tunnel Surgery: A Case Report
In this case report, we present a novel occurrence of acute hepatitis 2 weeks after local bupivacaine injection for wide awake, local anesthesia, no tourniquet carpal tunnel release. Laboratory and biopsy analysis confirmed cholestatic, drug-induced hepatitis that was successfully managed with conservative treatment. With a paucity of potential bupivacaine-induced hepatitis cases reported within the literature, the importance of broad differential diagnosis, meticulous medication reconciliation, and consideration of this rare complication should not be understated by the astute hand surgeon.No embarg
Outcomes After Stereotactic Body Radiation for Hepatocellular Carcinoma in Patients With Child-Pugh A Versus Child-Pugh B/C Cirrhosis
Purpose: For patients with hepatocellular carcinoma (HCC), stereotactic body radiation therapy (SBRT) has emerged as a locoregional treatment. Our purpose was to report outcomes in patients with HCC with Child-Pugh A (CP A) versus Child-Pugh B or C (CP B/C) liver dysfunction treated with SBRT.
Methods and materials: A retrospective analysis of 80 patients with HCC, with a total of 94 tumors treated with SBRT, was conducted at a single institution. Outcomes were compared between patients with CP A (n = 51) and CP B/C (n = 29) liver dysfunction. Outcomes of interest included local control, overall survival (OS), and toxicity.
Results: Median tumor size was 3.2 cm. There were 59 tumors included in the CP A cohort and 35 tumors in the CP B/C cohort. Median radiation dose was 50 Gy in 5 fractions for the CP A cohort and 40 Gy in 5 fractions for the CP B/C cohort. The rates of pathologic complete response were similar between the 2 groups at 63% for the CP A group and 61% for the CP B/C group. The estimated 1-year local control rates were similar between the 2 groups at 93% for the CP A group and 91% for the CP B/C group (P = .59). The 1-year OS for the CP A group was 85%, whereas the 1-year OS for the CP B/C group was 61% (P = .19). There was a 5.9% rate of grade 3+ toxicity in the CP A group and a 20.7% rate of grade 3+ toxicity in the CPB/C group.
Conclusions: Our findings suggest that SBRT is feasible and effective in patients with both CP A and CP B/C liver dysfunction with similar rates of local control and pathologic complete response despite lower radiation doses in the CP B/C cohort. In patients with more advanced CP B/C cirrhosis, toxicities were higher and must be weighed against possible treatment benefits. Further studies characterizing the optimal role of SBRT in patients with advanced cirrhosis are warranted.No embarg
Employment Outcomes among People with Disabilities: Work-Related Determinants
A systematic scoping review of research published between 2000 and 2020 on employment of people with disabilities, that was funded by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR), was conducted by CeKTER researchers. All papers comparing people with disabilities to those without were excluded from the systematic scoping review. Among over 100 publications reviewed there was a wide and very disparate array of findings with numerous variables used and varying research questions. This result belies summative findings. There are numerous ways of organizing the disparate findings. This brief is part of a series of findings from CeKTER’s systematic scoping review. In this brief we report on findings about a range of work-related determinants impacting the employment of people with disabilities, including work history, accommodations, workplace supports. Please note that all comparisons are always about corresponding peers with disabilities.The contents of this tip sheet were funded by the National Institute on Disability, Independent Living, and Rehabilitation Research (NIDILRR), Grant #90DPEM0004.

Strengthening Quality Measurement to Predict Success for Total Knee Arthroplasty: Results from a Nationally Representative Total Knee Arthroplasty Cohort
Background: When performed well on appropriate patients, total knee arthroplasty (TKA) can dramatically improve quality of life. Patient-reported outcome measures (PROMs) are increasingly used to measure outcome following TKA. Accurate prediction of improvement in PROMs after TKA potentially plays an important role in judging the surgical quality of the health-care institutions as well as informing preoperative shared decision-making. Starting in 2027, the U.S. Centers for Medicare & Medicaid Services (CMS) will begin mandating PROM reporting to assess the quality of TKAs.
Methods: Using data from a national cohort of patients undergoing primary unilateral TKA, we developed an original model that closely followed a CMS-proposed measure to predict success, defined as achieving substantial clinical benefit, specifically at least a 20-point improvement on the Knee injury and Osteoarthritis Outcome Score, Joint Arthroplasty (KOOS, JR) at 1 year, and an enhanced model with just 1 additional predictor: the baseline KOOS, JR. We evaluated each model's performance using the area under the receiver operator characteristic curve (AUC) and the ratio of observed to expected (model-predicted) outcomes (O:E ratio).
Results: We studied 5,958 patients with a mean age of 67 years; 63% were women, 93% were White, and 87% were overweight or obese. Adding the baseline KOOS, JR improved the AUC from 0.58 to 0.73. Ninety-four percent of those in the top decile of predicted probability of success under the enhanced model achieved success, compared with 34% in its bottom decile. Analogous numbers for the original model were less discriminating: 77% compared with 57%. Only the enhanced model predicted success accurately across the spectrum of baseline scores. The findings were virtually identical when we replicated these analyses on only patients ≥65 years of age.
Conclusions: Adding a baseline knee-specific PROM score to a quality measurement model in a nationally representative cohort dramatically improved its predictive power, eliminating ceiling and floor effects and mispredictions for readily identifiable patient subgroups. The enhanced model neither favors nor discourages care for those with greater knee dysfunction and requires no new data collection.

Shared Medication Planning In Home Hospice to Address Medication Regimen Complexity and Family Caregiver Burden: A Brief Report
Medication management in home hospice is challenging for family caregivers (FCGs). We tested a patient-centered medication review and FCG support program delivered by hospice staff called "Shared Medication PLanning In (SiMPLIfy) Home Hospice." A pilot cluster-randomized trial at two U.S. home hospice agencies measured the primary outcome of reduction in Medication Regimen Complexity Index (MRCI) (range 0 [no medications]-no upper limit) and secondary outcome of Family Caregiver Medication Administration Hassle Scale (FCMAHS) (range 0 [no hassle-120 [greatest hassle]). Twenty-two patient-FCG dyads enrolled. Mean baseline MRCI in the intervention group = 39 (95% CI: 30.9, 47.1) and control group = 25.5 (95% CI: 21.0-30.1). Half of intervention patients (3 of 6) had reduced MRCI compared with 26.7% (4 of 15) control patients ( = 0.07). MRCI was not significantly associated with caregiver burden. FCMAHS differed between spousal and nonspousal FCGs ( = 0.12). A clinician-FCG-patient communication program in home hospice is feasible and may reduce medication complexity. SiMPLIfy has the potential to reduce polypharmacy.No embarg
Ten simple rules for recognizing data and software contributions in hiring, promotion, and tenure
The ways in which promotion and tenure committees operate vary significantly across universities and departments. While committees often have the capability to evaluate the rigor and quality of articles and monographs in their scientific field, assessment with respect to practices concerning research data and software is a recent development and one that can be harder to implement, as there are few guidelines to facilitate the process. More specifically, the guidelines given to tenure and promotion committees often reference data and software in general terms, with some notable exceptions such as guidelines in [5] and are almost systematically trumped by other factors such as the number and perceived impact of journal publications. The core issue is that many colleges establish a scholarship versus service dichotomy: Peer-reviewed articles or monographs published by university presses are considered scholarship, while community service, teaching, and other categories are given less weight in the evaluation process. This dichotomy unfairly disadvantages digital scholarship and community-based scholarship, including data and software contributions [6]. In addition, there is a lack of resources for faculties to facilitate the inclusion of responsible data and software metrics into evaluation processes or to assess faculty’s expertise and competencies to create, manage, and use data and software as research objects. As a result, the outcome of the assessment by the tenure and promotion committee is as dependent on the guidelines provided as on the committee members’ background and proficiency in the data and software domains.
The presented guidelines aim to help alleviate these issues and align the academic evaluation processes to the principles of open science. We focus here on hiring, tenure, and promotion processes, but the same principles apply to other areas of academic evaluation at institutions. While these guidelines are by no means sufficient for handling the complexity of a multidimensional process that involves balancing a large set of nuanced and diverse information, we hope that they will support an increasing adoption of processes that recognize data and software as key research contributions
Normative Modeling of Thalamic Nuclear Volumes and Characterization of Lateralized Volume Alterations in Alzheimer's Disease Versus Schizophrenia
Background: Thalamic nuclei facilitate a wide range of complex behaviors, emotions, and cognition and have been implicated in neuropsychiatric disorders including Alzheimer's disease (AD) and schizophrenia. The aim of this work was to establish novel normative models of thalamic nuclear volumes and their laterality indices and investigate their changes in schizophrenia and AD.
Methods: Volumes of bilateral whole thalami and 10 thalamic nuclei were generated from T1 MRI data using a state-of-the-art novel segmentation method in healthy control subjects (n=2374) and early mild cognitive impairment (MCI, n=211), late MCI (n=113), AD (n=88), and schizophrenia (n=168). Normative models for each nucleus were generated from healthy control subjects while controlling for sex, intracranial volume, and site. Extreme z-score deviations (|z|>1.96) and z-score distributions were compared across phenotypes. Z-scores were associated with clinical descriptors.
Results: Increased infranormal and decreased supranormal z-scores were observed in schizophrenia and AD. Z-score shifts representing reduced volumes were observed in most nuclei in schizophrenia and AD with strong overlap in the bilateral pulvinar, medial dorsal, and centromedian nuclei. Shifts were larger in AD with evidence of a left-sided preference in early MCI while a predilection for right thalamic nuclei was observed in schizophrenia. The right medial dorsal nucleus was associated with disorganized thought and daily auditory verbal hallucinations.
Conclusion: In AD, thalamic nuclei are more severely and symmetrically affected while in schizophrenia, the right thalamic nuclei are more affected. We highlight the right medial dorsal nucleus, which may mediate multiple symptoms of schizophrenia and is affected early in the disease course
