Authors: Sabatino Meagan J. , Sullivan Kate , Alcusky Matthew J. , Nicholson Joanne 
Published: October 2024

Abstract
Background
Multiple state and national health care organizations have invested in activities to screen for and address the health-related social needs (HRSNs) of their patients. However, patient perspectives concerning HRSN screening discussions and facilitated referrals to supports are largely unexplored. The main objectives of this study were to explore the ways in which Massachusetts Medicaid (MassHealth) members engage with their health care clinicians to discuss HRSNs, to identify common needs discussed, and to describe whether members feel these needs are being addressed by health care clinicians and staff.

Methods
The study team performed a cross-sectional, qualitative research study that included in-depth, open-ended interviews with 44 adult MassHealth members. Interviews were conducted between June and October 2022. Interviews were recorded, transcribed, and systematically coded for analysis, and common themes were reported. The data collected for this study were part of a larger independent evaluation of MassHealth’s 2017-2022 Section 1115 Demonstration that granted authority from CMS to implement health care delivery system reforms in Massachusetts.

Results
In this qualitative study of Medicaid members, some reportedly felt comfortable freely discussing all of their clinical and social needs with their health care clinicians, while others noted feelings of apprehension. Several members recalled being asked about their HRSNs in various clinical or community settings, while others did not. The majority of members endorsed having an unmet HRSN, including housing, nutrition, financial, or transportation issues, and many barriers to addressing these HRSNs were discussed. Finally, many members cited a preference for discussing HRSNs with community-based care coordinators and social workers at the community partner organizations rather than with their health care clinicians. Community-based care coordinators were lauded as essential facilitators in making the connection to necessary resources to help address HRSNs.

Conclusions
Study results highlight an opportunity to increase the effectiveness of HRSN screening and referral practices within the health care setting through relationship building between Medicaid members and diverse interdisciplinary care teams that include staff such as community health workers. Continued investment in cross-sector partnerships, screening workflows, and patient-clinician relationships may contribute to establishing an environment in which members can comfortably discuss HRSNs and connect with needed services to improve their health.
Medical student perceptions of gender and pain: a systematic review of the literature
Authors: Patrick-Smith Maia , Bull Stephanie 
Published: October 2024

Abstract

Background
Gender bias exists in healthcare and affects how pain is assessed and managed. This bias affects patient outcomes and their trust in healthcare professionals. We also know that future clinicians develop their attitudes early in training. Medical school is therefore an opportunity to shape the values of future doctors and to combat systemic gender bias in healthcare. This systematic review aims to explore medical student perceptions of the relationship between patients’ gender and their pain, so that recommendations can be made for developing medical education.

Methods
Embase, MEDLINE, PsychINFO, LILACS, Global Index Medicus, PakMediNet and ERIC were searched for articles relating to medical student perceptions of gender and pain, with no geographical or language limitations. Quality was assessed using the Medical Education Research Study Quality Index and the Critical Appraisal Skills Programme checklist.

Results
Nine publications were identified, two qualitative and seven quantitative. All studies had methodological limitations. Many different study designs were used, although most involved simulated patients. All studies referred to gender as binary. Multiple studies found that women’s pain is more likely to be underestimated by medical students and that the patient’s gender drives different approaches during clinical history taking, examination and management in these simulated situations. Only one study found no effect of patients’ gender on students’ perception of their pain.

Conclusions
Whilst there is a paucity of high-quality studies in this area, patients’ gender was found to affect how their pain is perceived by medical students. No studies explored where students’ attitudes towards gender and pain arise from, and few involved ‘real life situations’. We propose that further work into medical student perceptions in ‘real situations’ is needed. This will help to inform how undergraduate medical education can be developed to tackle gender bias, and ultimately improve outcomes for patients.

Abstract

Background

Increased levels of physical activity are associated with a reduction of breast cancer mortality, especially in postmenopausal women with positive hormone receptor status. So far, previous observational case–control and cohort studies have focused on associations between overall leisure time physical activity and survival of women with breast cancer in general.

Methods
In this multicenter prospective cohort study, conducted in Germany between 30th August 2012 to 29th December 2017, we investigated general physical activity in a homogenous sample of n = 1440 postmenopausal women with advanced (inoperable locally advanced or metastatic), hormone receptor-positive breast cancer receiving the same therapy (everolimus and exemestane). Self-reported physical activity was assessed using the Godin Leisure Time Exercise Questionnaire (GLTEQ) before and every 3 months during treatment. Participants were then classified into “active” and “insufficiently active” to screen their activity behavior the week prior to medical treatment. In addition, changes in physical activity patterns were assessed. Adjusted Cox regression analyses were performed for the activity categories to determine hazard ratios (HR). Besides progression-free survival (PFS), adverse events (AEs), QoL, and fatigue were assessed every 3 months until study termination.

Results
Compared to “insufficiently active” patients, “active” individuals indicated a significantly longer PFS (HR: 0.84 [0.74; 0.984], p = .0295). No significant differences were observed for changes of physical activity behavior. Patients who reported to be “active” at baseline revealed significantly fewer AEs compared to “insufficiently” active patients. In detail, both severe and non-severe AEs occurred less frequently in the “active” patients group. In line with that, QoL and fatigue were better in physical “active” patients compared to their insufficient active counterparts at the last post-baseline assessment. Participants who remained or become active indicated less AEs, a higher QoL, and reduced fatigue levels.

Conclusions
Physical activity behavior prior to medical treatment might have prognostic value in patients with advanced breast cancer in terms of extending the PFS. Moreover, physical activity before and during treatment may reduce treatment-related side effects and improve patients’ QoL and fatigue.

Published: October 2024

Abstract
Background
An important methodological challenge in conducting pediatric economic evaluations is estimating the preference-based health-related quality of life (HRQoL) of children. Current methods are highly variable and there is no single instrument available to value HRQoL consistently across multiple pediatric age groups. The Pediatric Quality of Life Inventory (PedsQL) is a non-preference-based generic HRQoL instrument validated for children 2–18 years, but it cannot be directly used in economic evaluations. The aim of this study was to establish the core dimension structure of the PedsUtil health state classification system using confirmatory factor analysis, which is the first step of deriving a preference-based measure of HRQoL based on the PedsQL.

Methods
Four competing dimension structures of the PedsUtil health state classification system were developed based on published literature and expert opinion. Using data from the Longitudinal Study of Australian Children (LSAC) (n = 45,207), the 4 dimension structures were evaluated using the robust weighted least squares estimation method. The analyses were stratified by 2-year age intervals (from 2 to 17 years) to reflect the study design of the LSAC, as well as special healthcare needs status of the child. Model fit was evaluated by examining standardized factor loadings and various fit indices including the comparative fit index (CFI), Tucker-Lewis Index (TLI), and the root mean square error of approximation (RMSEA). Modification indices and residual correlations were examined to re-specify the models to improve model fit when necessary.

Results
The findings supported a 7-dimension structure (i.e., Physical Functioning, Pain, Fatigue, Emotional Functioning, Social Functioning, School Functioning, and School Absence) of the PedsUtil health state classification system. The 7-dimension model exhibited adequate fit across subgroups with CFI values that ranged from 0.929 to 0.954, TLI values from 0.916 to 0.946, and RMSEA values from 0.058 to 0.102.

Conclusions
This study established the core dimension structure of the PedsUtil health state classification system using confirmatory factor analysis. The 7-dimension structure was found to be applicable across diverse pediatric populations. Research is currently ongoing to select the most representative item within each dimension of the PedsUtil health state classification system and valuation surveys will be fielded to estimate the PedsUtil scoring system.

Published: October 2024

Abstract
Background
The IL-7 receptor alpha (IL-7Rα) binds both IL-7 and thymic stromal lymphopoietin (TSLP). IL-7Rα is essential for the development and survival of naive CD4+ T cells and their differentiation to effector/memory CD4+ T cells. Mice lacking IL-7Rα have severe lymphopenia and are resistant to experimental autoimmune encephalomyelitis (EAE), a model for multiple sclerosis. However, it has been reported that IL-7Rα on peripheral CD4+ T cells is disposable for their maintenance and EAE pathogenesis, which does not align with the body of knowledge on the role of IL-7Rα in the biology of CD4+ T cells. Given that a definitive study on this important topic is lacking, we revisited it using a novel approach, an inducible knockout of the IL-7Rα gene in CD4+ T cells.

Methods
We generated Il7rafl/fl/CD4CreERT2 double transgenic mouse line (henceforth CD4ΔIl7ra), susceptible to tamoxifen-induced knockout of the IL-7Rα gene in CD4+ T cells. CD4ΔIl7ra mice were immunized with MOG35 − 55 for EAE induction and monitored for disease development. The expression of IL-7Rα, CD4+ T cell numbers, and MOG35 − 55-specific CD4+ T cell response was evaluated in the central nervous system (CNS) and lymphoid tissues by flow cytometry. Additionally, splenocytes of CD4ΔIl7ra mice were stimulated with MOG35 − 55 to assess their proliferative response and cytokine production by T helper cells.

Results
Loss of IL-7Rα from the surface of CD4+ T cells in CD4ΔIl7ra mice was virtually complete several days after tamoxifen treatment. The loss of IL-7Rα in CD4+ T cells led to a gradual and substantial decrease in their numbers in both non-immunized and immunized CD4ΔIl7ra mice, followed by slow repopulation up to the initial numbers. CD4ΔIl7ra mice did not develop EAE. We found a decrease in the total numbers of TNF-, IFN-γ-, IL-17 A-, and GM-CSF-producing CD4+ T cells and regulatory T cells in the spleens and CNS of immunized CD4ΔIl7ra mice. Tracking MOG35 − 55-specific CD4+ T cells revealed a significant reduction in their numbers in CD4ΔIl7ra mice and decreased proliferation and cytokine production in response to MOG35 − 55.

Conclusion
Our study demonstrates that IL-7Rα on peripheral CD4+ T cells is essential for their maintenance, immune response, and EAE pathogenesis.

Abstract
Background
The high psychological burden of rape, together with complications such as pregnancy and chronic conditions, is associated with an increase in mental disorders. Social cognitive theory (SCT) is an important health theory that views behavior as dynamic and influenced by environmental, behavioral and individual factors. The aim of the present research is to determine the effect of an educational intervention on post-traumatic stress disorder and social cognitive theory constructs in women who have experienced sexual assault.

Methods/design
This study is randomized, double-blind clinical trial research that will be conducted on 40 women with experience of sexual. In this research, by the intervention program based on social cognitive theory include" awareness, self-efficacy, outcome expectations and environment. Written consent will be obtained from the participants to participate in the research. Participants in the intervention group will be taught about health, hygiene, psychology and stress reduction methods in group or individual sessions according to their preference in 6 sessions of 60 min each, one session per week. A post-test will be conducted for both groups.

Discussion
This study provides comprehensive data on the effect of providing an educational intervention using the social cognition Theory. Social cognitive theory focuses on how patterns of behavior are learned and how they function in interaction between the individual and the environment. It seems that the use of this theory in designing the content of educational interventions can be useful and practical.

Published: October 2024

AbstractPlants such as herbs, vegetables, fruits, and cereals are closely related to human life. Developing effective testing methods to ensure their safety and quantify their active components are of significant importance. Recently, nanomaterials with enzyme-like activity (known as nanozymes) have been widely developed in various assays, including colorimetric, fluorescence, chemiluminescence, and electrochemical analysis. This review presents the latest advances in analyzing phytochemicals and hazardous substances in plant samples based on nanozymes, including some active ingredients, organophosphorus pesticides, heavy metal ions, and mycotoxins. Additionally, the current shortcomings and challenges of the actual sample analysis were discussed.

Published: October 2024

Abstract
Background
We assessed long-term real-world effectiveness and safety of lomitapide in patients with homozygous familial hypercholesterolemia (HoFH).

Methods
Retrospective case series of six patients with HoFH treated with lomitapide in an Italian clinic. Changes in low-density lipoprotein cholesterol (LDL-C) during lomitapide treatment were assessed. The effect on LDL-C of PCSK9 inhibitors, apheresis and lomitapide was evaluated. Additionally, high-density lipoprotein cholesterol (HDL-C), gastrointestinal tolerability, hepatic steatosis/elasticity, transaminases, and cardiovascular events and symptoms were assessed.

Results
Median age at HoFH clinical and molecular diagnoses was 25 (range 2–49) and 40 (29–71) years, respectively. Five (83.3%) had prior cardiovascular events. One patient received apheresis, which was subsequently discontinued. All patients received PCSK9 inhibitors but discontinued due to minimal effectiveness. Median (range) age at lomitapide initiation was 44 (28–73) years, with a median 47 (18–85) months’ treatment (mean dose 17.5 [5–40] mg/day). Mean (SD) baseline LDL-C was 263.2 (148.1) mg/dL, which decreased by 80% at nadir (52.8 [19.2] mg/dL) and 69% at last follow-up (81.3 [30.5] mg/dL). Four patients (66.7%) achieved LDL-C < 70 mg/dL sometime during follow-up, all of whom also achieved LDL-C < 55 mg/dL. Adverse events (AEs) were generally mild to moderate, hepatic steatosis was either absent or mild/moderate and hepatic elasticity remained normal in all but two patients (> 70 years old). All patients with reported cardiovascular symptoms had improvements in symptoms, and all patients reported stabilization or regression of intima-media thickness and atheromatous plaques.

Conclusions
These long-term, real-world data demonstrate that lomitapide substantially reduced LDL-C for up to seven years. Most patients achieved LDL-C goal at some point, consistent with published Phase III trial and real-world evidence data. No patient discontinued lomitapide treatment. Further long-term follow-up in a larger patient population will be important to determine cardiovascular and other outcomes.
Redefining chimeric antigen receptor T-cell (CAR-T) regulation: China’s responses to address secondary cancer risks of CAR-T therapy
Authors: Tan Ruirong , Li Rui , Dai Meng-Yuan , Liu Miao , Zhao Junning 
Published: October 2024

AbstractSince the United States Food and Drug Administration (FDA) approved the first chimeric antigen receptor T-cell (CAR-T) therapy in 2017, it has marked a major breakthrough in cancer treatment, leading to a surge in global research and applications in this field. In recent years, China has made rapid progress, quickly catching up through heavy investment in CAR-T construction, preparation processes, and treatment strategies. China’s CAR-T therapy market is driven by substantial pharmaceutical investment targeting its vast population, yet high therapy costs remain uncovered by basic medical insurance. In November 2023, FDA issued a warning about the risk of secondary cancers in patients undergoing CAR-T therapy, sparking global concern. In fact, the China National Medical Products Administration (NMPA) preemptively implemented a series of measures to address the safety concerns of CAR-T therapy, emphasizing the risk of secondary cancers and advising lifelong monitoring as part of the approval process for CAR-T products. Nevertheless, additional regulatory measures are needed to address emerging risks, particularly the threat of secondary cancers. The authors believe that raising the standards for Investigational New Drug (IND) approval and establishing a dynamic reporting and feedback system based on real-world data will strengthen regulatory oversight and support the sustainable growth of the CAR-T industry in China.
Prehospital undertriage of older injured patients in western Switzerland: an observational cross-sectional study
Authors: Poncet Clément , Carron Pierre-Nicolas , Darioli Vincent , Zingg Tobias , Ageron Francois-Xavier 
Published: October 2024

Abstract
Background
The ageing of the population is leading to an increase in the number of traumatic injuries and represents a major challenge for the future. Falls represent the leading cause of Emergency department admission in older people, with injuries ranging from minor to severe multiple injuries. Older injured patients are more likely to be undertriaged than younger patients. The aim of this study was to investigate the extent of undertriage in older patients with particular emphasis on access to trauma centres and resuscitation rooms.

Methods
Retrospective observational cross-sectional study based on data prospectively collected from prehospital electronic records including all patients ≥ 18 years for whom an ambulance or helicopter was dispatched between 1 January 2018 and 31 April 2023 due to a trauma. The primary outcome, admission to the resuscitation room of the regional trauma centre with trauma team activation, was assessed by age. Multivariate logistic regression was used to control for known confounders and to test for plausible effect modifiers.

Results
Emergency Medical Services treated 37,906 injured patients. Older patients ≥ 75 years represented 17,719 patients (47%). Admission to trauma centre with trauma team activation was lower in older patients, N = 121 (1%) compared to N = 599 (5%) in younger patients, p < 0.001; adjusted odds ratio: 0.33 (0.24–0.45); p < 0.001. Undertriage increased by twofold with age ≥ 75; OR: 1.81 (1.04–3.15); p value < 0.001. Undertriaged patients were older, more likely to be female, to have low energy trauma and to be located farther from the regional trauma centre.

Conclusion
Older injured patients were at increased risk of undertriage and non-trauma team activation admission, especially if they were older, female, had head injury without altered consciousness and greater distance to regional trauma centre.
