ABSTRACT

BACKGROUND: The link between regional body fat distribution and overactive bladder (OAB) in prior epidemiological research has been uncertain. Our objective is to assess the relationship between increased regional body fat and the prevalence of OAB.

METHODS: Within this analysis, 8,084 individuals aged 20 years and older were selected from NHANES surveys conducted from 2011 to 2018. The evaluation of OAB symptoms utilized the overactive bladder symptom score (OABSS). Fat mass (FM) across various regions was quantified employing dual-energy X-ray absorptiometry, which assessed total FM, trunk FM, arm FM, and leg FM. The fat mass index (FMI) was calculated as the ratio of fat mass (kg) to the square of height (meters). Data weighting was performed in accordance with analysis guidelines. A linear logistic regression model was employed to assess the correlation between regional FMI and the occurrence of OAB. Stratified analyses were also conducted.

RESULTS: The study found significant associations between total FMI and limb FMI with OAB. After adjusting for all variables in the analysis, higher total FMI (OR = 1.07, 95% CI = 1.02-1.12) was linked to an increased risk of OAB. Trunk FMI (OR = 1.12, 95% CI = 1.03-1.22), arm FMI (OR = 1.59, 95% CI = 1.20-2.10), and leg FMI (OR = 1.12, 95% CI = 1.01-1.25) demonstrated significant correlations with OAB. The weighted associations between total FMI and limb FMI with OAB incidence showed no significant differences among most subgroups.

CONCLUSIONS: The data indicates a correlation between higher regional FMI and increased OAB risk across different populations.

ABSTRACT

BACKGROUND: Traditional cognitive assessments, often reliant on paper-and-pencil tests and professional evaluators, suffer from subjectivity and limited result discrimination. This study introduces the Baguan Online Cognitive Assessment System (BOCAS), a tablet-based system that evaluates both general cognitive ability (GCA) and domain-specific functions across six domains: sensory-motor skills, processing speed, sustained attention, working memory, cognitive flexibility, and spatial ability.

METHODS: BOCAS was validated with 151 healthy Chinese adults aged 18-40. Reliability was assessed through internal consistency and test-retest reliability. Factor analysis and confirmatory factor analysis (CFA) were used to validate the model. The GCA score was correlated with the Raven IQ test and self-reported cognitive flexibility, and its relationship with negative emotions (depression and anxiety) was examined.

RESULTS: BOCAS showed satisfactory reliability, with internal consistency ranging from 0.712 to 0.846 and test-retest reliability from 0.56 to 0.71. Factor analysis revealed a common factor explaining 40% of the variance, and CFA indicated a good model fit (χ²/df = 1.81; CFI = 0.932). The GCA score strongly correlated with the Raven IQ test (r = 0.58) and was related to self-reported cognitive flexibility and negative emotions.

CONCLUSION: BOCAS offers a digital solution for cognitive assessment, providing automated, remote, and precise evaluations. It demonstrates reliability, validity, and potential for use in clinical and research settings.

ABSTRACT

BACKGROUND: Suicide prevention programs delivered in school settings have been shown to reduce suicide attempts and ideation among adolescents. School-based digital interventions targeting at-risk youth are a promising avenue for suicide prevention, and some evidence has shown that blending digital and face-to-face components may improve the effectiveness. However, further evidence is needed, especially in Latin America, where mental health support is limited. We tested the effectiveness of the Reframe-IT+, a blended cognitive behavioral indicated intervention to reduce suicidal ideation, designed to be delivered in school settings. It includes 13 sessions, combining eight internet-based sessions and five face-to-face sessions.

METHODS: We conducted a cluster RCT and delivered the Reframe-IT + among secondary students attending Years 9-11. We recruited 21 schools that were randomized into two groups: (1) Intervention Reframe-IT + Group (IG) (n = 863) and (2) Control Group (CG) (n = 683). All consented students completed online screening self-reported questionnaires at baseline. The primary outcome was suicidal ideation . Additionally, we tested the impact of the intervention on depressive and anxiety symptoms, hopelessness, and emotion regulatory strategies, including social solving-problems skills, behavioral activation, cognitive reappraisal, and emotion suppression. A total of 303 students (IG, n = 164; CG, n = 139) were identified as at risk and eligible for inclusion in the study. From those, 224 students (IG, n = 123; CG, n = 101) and their caregivers were interviewed to confirm inclusion and exclusion criteria. Finally, 48 and 47 students were allocated to control and intervention groups, respectively, and answered the online questionnaires at post-intervention. We performed an intention-to-treat analysis using repetitive measures and multilevel regression analyses.

RESULTS: We found a significant reduction in suicidal ideation (b=-6.7, p = 0.015, Cohen´s d = 0.49), depressive (b=-3.1, p = 0.002, Cohen´s d = 0.81) and anxiety (b=-2.60, p < 0.001, Cohen´s d = 0.72) symptoms, and hopelessness (b=-3.7, p < 0.001, Cohen´s d = 0.70) in the intervention group compared to the control group at post-intervention. We also found improvement in solving-problems skills (b=-1.6, p = 0.002, Cohen´s d = 0.58), behavioral activation (b = 2.8, p = 0.019, Cohen´s d = 0.47), and cognitive reappraisal (b = 2.2, p = 0.029, Cohen´s d = 0.53). In the exploration of the intervention mechanisms concerning suicidal ideation, the total indirect effect of the intervention (b = -5.727923; p = 0.008) was significant, whereas the direct effect (b = – 0.03195473, p = 0.903) was not significant (Suppl 2, Table 1). Problem-solving skill (b=-2.84, p = 0.016) was a significant mediator of intervention effects on suicidal ideation (Path a*b).

CONCLUSIONS: This is the first clustered RCT evaluation of the effectiveness of a blended indicated intervention to prevent suicidality in school settings in Latin America. This is the first step to informing policymakers to scale up an effective intervention for an important public health problem.

ABSTRACT

BACKGROUND: There is widespread enthusiasm for scaling interventions to strengthen health systems. However, little is known about the scalability of such interventions in Africa. In this study, we seek to assess the scalability of interventions for improving the functionality of health systems in Africa, as a key to large-scale implementation strategy of interventions with potential for impact.

METHODS: The study will deploy a multi-pronged approach, grounded in an integrated knowledge translation (iKT) approach. First, a multidisciplinary steering committee will be established, involving key female and male stakeholders in all stages of our study from its inception and as equal members of the research team for overseeing the project. Second, as part of the RAND/University of California, Los Angeles (UCLA) Appropriateness Method, evidence from a published systematic review will be used to develop the African Scalability Assessment Framework (AFROSAF), a series of multiple attributes for assessing the ability to scale a health system intervention in Africa. Third, the content of the AFROSAF will be validated using Delphi survey (within a deliberative dialogue) following the Lavis’ framework for knowledge transfer and a conceptual framework developed by Boyko et al. a multi-stakeholder consensus exercise with experts from Africa will be convened. The Likert scaled scalability attributes developed will be rated and descriptive statistics and hierarchical cluster analysis will be used to synthesize the data. Finally, document analyses will be conducted to rate to which extent each intervention has data that meet criteria responding to the essential components of scalability using the AFROSAF. We will conduct an analysis to score and rank each intervention for scalability.

DISCUSSION: This project proposes an approach aiming to catalyse the scale of interventions for effective functionality of health systems in Africa. The process will yield a scalability assessment tool for Africa and inventory scalable interventions. The findings will help African countries and policymakers understand the parameters to use and assess health system interventions for scaling.

ABSTRACT

OBJECTIVE: This study aimed to investigate a range of insomnia-related factors, including difficulty with sleep induction, nocturnal awakenings, early awakenings, total sleep time, overall sleep quality, well-being, functioning, and daytime drowsiness, to determine which variables were significantly associated with subsequent adolescent suicide attempts.

METHOD: A total of 782 students aged 11-16 years old from one middle school in Changsha, China completed the survey at baseline and 6 months follow-up with a prospective cohort design. The binary logistic regression models were used to analyze the associations between insomnia variables and suicide attempts during the 6 months follow-up.

RESULTS: The new incidence rate of suicide attempts was 4.60% (36/782) at 6-month follow-up. Insomnia was a significant predictor of incident suicide attempts (OR = 6.00; 95%CI, 2.47-14.60). After adjusting for age, gender, nationality, stress, anxiety and depression, insomnia was found to predict suicide attempts only among female (OR = 4.28; 95%CI, 1.41-12.98) and only nocturnal sleep disruption was significantly associated with an increased risk of suicide attempts (OR = 2.74; 95%CI, 1.32-5.71).

CONCLUSIONS: Nocturnal sleep disruption are independently associated with increased risk of suicide attempts. Intervention for nocturnal sleep disruption may be important for early identification as well as prevention of adolescent suicide, especially among adolescent girls.

ABSTRACT

BACKGROUND: Measles is a very contagious illness that can be clinically diagnosed and intervened quickly. It is caused by the measles virus Morbillivirus. The disease has a case fatality rate of 5% to 10% in the sub-Saharan region. Recent information on measles forecasting is limited in this study area. Therefore, this study was aimed to assess the five-year trend and next five-year prediction of measles disease in East Gojjam zone, Amhara National Regional State (ANRS), Ethiopia, 2023.

METHODS: A descriptive study using case based surveillance data analysis in the East Gojjam zone was conducted. Five-year data (January 1/2018-December 30/2022) was extracted from the WHO database. ARIMA (3, 1, 1) model was used for disease forecasting for the next 5 years of the zone (2023-2027).

RESULTS: For the study, 1003 participants in total were enlisted. 12.3% of the subjects were IgM positive. About 59.4% and 1.2% were epidemiologically linked and died subjects, respectively. Many of the cases (54.2%) occurred in the March season and the lowest (1%) in December. For the next five years (2024-2027), it is predicted that the number of cases will rise gradually in fluctuation.

CONCLUSION: The disease had an upward trend over the five-year period, and for the next consecutive years, there will be a consistent increase in the number of cases in the zone. It is recommended that the East Gojjam Zone Health Office and different stakeholders have to monitor and evaluate the vaccination status of target children and vaccination coverage and strengthen the surveillance system in the dry-hot season, which is valuable for disease control.

ABSTRACT

BACKGROUND: This study explored the relationship between Adverse Childhood Experiences (ACE), physical pain, and depressive symptoms, and examined the mediating role of pain in the correlation between ACE and depressive symptoms among middle-aged and elderly Chinese (over the age of 45).

METHODS: Cox proportional hazards regression models were used to analysis the association between ACE, physical pain, and depressive symptoms. To assess the mediating role of physical pain in the relationship between ACE and depressive symptoms, mediation analysis was conducted. Indirect, direct, and total effects were estimated by combining mediation and outcome models, adjusting for relevant covariates. Bayesian network models were used to visually demonstrate the interrelations between factors influencing depressive symptoms, further verifying the association between ACE, physical pain, and depressive symptoms.

RESULTS: In the fully adjusted model, middle-aged and elderly individuals reporting ACE had a higher risk of developing depressive symptoms (hazard ratios [HR] and 95% confidence intervals [95% CI], 1.379 [1.266-1.503]). Compared to those without physical pain, individuals reporting severe physical pain were at an increased risk of depressive symptoms (HR [95% CI], 1.438 [1.235-1.673]). The risk was even higher for those with both ACE and severe physical pain compared to those with neither (HR [95% CI], 2.020 [1.630-2.505]). The intensity of pain explained 7.48% of the association between ACE and depressive symptoms, while the number of pain sites accounted for 7.86%.

CONCLUSIONS: Physical pain partially mediated the association between ACE and depressive symptoms. The study findings highlighted the importance of early screening and intervention for physical pain in middle-aged and older adults with ACE.

ABSTRACT

INTRODUCTION: Although the Government of Nepal has developed strategies to integrate contraceptive services with abortion care to better meet the contraceptive needs of women, data indicate that significant gaps in services remain. This paper assessed post-abortion contraceptive use, trends over 36 -months, and factors influencing usage.

METHODS: Data from this paper came from an ongoing cohort study of 1831 women who sought an abortion from one of the sampled 22 government-approved health facilities across Nepal. Women were interviewed eight times over 36 months between April 2019 to Dec 2023. Bivariate and multivariate analysis were used to analyze the data.

RESULTS: Results show that after abortion, 59% of women used modern contraception, with injection being the most prevalent method, followed by condoms, pills, implants, and IUD. The hazard model showed that discontinuation of modern contraception was significantly higher among women desiring additional children (aHR 0.62) and lower among literate (aHR – 0.15) and those with existing children (aHR – 0.30). Women’s age, ethnicity, cohabitation with husband, household’s income and autonomy were not associated with continuation.

CONCLUSION: After having an abortion, we found that just slightly more than half of women used modern methods of contraception; this percentage did not increase significantly over the course of three years.

ABSTRACT

AIM: To evaluate the clinical efficacy and imaging outcomes of a domestically produced orthopedic surgical robot for total knee arthroplasty and to explore its applicability in patients with varying degrees of deformity.

METHODS: This study retrospectively included 120 patients who underwent TKA at our hospital between February 2023 and June 2024. The patients were divided into a control group (conventional TKA surgery) and an observation group (robot-assisted TKA surgery), with 60 patients in each group. Based on different lower extremity alignment angles, each group was further subdivided into mild deformities (Hip knee ankle angle (HKA angle)deviation < 10°) and significant deformities (HKA angle deviation ≥ 10°). Preoperative and postoperative HKA angles, range of motion (ROM), visual analog scale (VAS) pain scores, and Knee Society (AKS) scores were recorded for both groups. Postoperative measurements included the posterior tibial slope angle (PSA), femoral coronal component angle (FFC), tibial coronal component angle (FTC), and femoral sagittal component angle (LFC), as well as the incidence of abnormal values for each angle, which were analyzed statistically.

RESULTS: The operation time in the observation group was longer than that in the control group, but intraoperative blood loss was significantly lower in the observation group (P < 0.05). Postoperatively, the differences in the HKA and PSA angles and the incidence of abnormal values were significantly better in the robot-assisted group than in the control group (P < 0.05). The other indicators did not significantly differ between the two groups. (P > 0.05). For patients with mild preoperative deformities, those in the robot-assisted group had significantly better postoperative HKA angle deviations and rates of postoperative HKA angle outliers than those in the conventional group. For patients with significant deformities, the robot-assisted group presented greater postoperative HKA and PSA angle deviations than the control group; the postoperative HKA and PSA angle outlier rates were significantly lower in the robot-assisted group (P < 0.05).

CONCLUSION: The TINAVI robotic system demonstrated superior safety and efficacy in TKA surgery. Compared with conventional TKA, the robot-assisted system achieved significantly better outcomes regarding prosthesis implantation accuracy and lower extremity alignment, with a particular advantage in patients with severe limb alignment deformities.

ABSTRACT

Alzheimer’s Disease (AD) is a debilitating neurodegenerative disease that affects 47.5 million people worldwide. AD is characterised by the formation of plaques containing extracellular amyloid-β (Aβ) and neurofibrillary tangles composed of hyper-phosphorylated tau proteins (pTau). Aβ gradually accumulates in the brain up to 20 years before the clinical onset of dementia, making it a compelling candidate for early detection of AD. It has been shown that there is increased deposition of Aβs in AD patients’ retinas. However, little is known about microglia’s ability to function and clear Aβ within the retina of AD and control eyes. We labelled microglia with ionised calcium-binding adaptor molecule 1 (IBA-1) in AD and age-matched control donor retinas. We then used interactive machine learning to segment individual microglia in 3D. In the temporal mid-peripheral region, we found that the number of microglia was significantly lower in AD retinas compared to controls. Unexpectedly, the size of the microglia was significantly larger in the AD retinas compared to controls. We also labelled retinal microglia for Cluster of Differentiation 68 (CD68), a transmembrane glycoprotein expressed by cells in the monocyte lineage and a marker of phagocytic activity and activated microglia. The size of CD68 + cells was statistically different between AD and control microglial, with CD68 + cells being larger in AD. In contrast, there was no difference in either size or shape for CD68- microglia between the two groups, suggesting an important difference in the active states of CD68 + microglia in AD retina. There was also significantly increased CD68 immunoreactivity in individual microglia within the AD group. Overall, this study reveals unique differences in the size and activity of the retinal microglia, which may relate to their potential chronic activation due to increased levels of Aβs in the AD retina.
