Teenage Blues: Predictors of depression among adolescents in Nigeria.

BACKGROUND: Depressive disorders, with a prevalence of 15-21%, are among the most common disorders in children and adolescents, and increases the risk of suicide, the second leading cause of death in children aged 10 to 19. AIM: To determine the prevalence and correlates of depressive disorders among senior students attending secondary schools in Abeokuta. METHOD: The study was conducted in five schools randomly selected from a representative sample and was carried out in 2 phases. In the first phase, students were selected via systematic random sampling and given consent forms and GHQ-12 to administer to the parents. In the second phase, students who returned a signed informed consent form and filled out GHQ-12 were interviewed using MINI-KID, Rosenberg's Self-Esteem Scale, Family-APGAR, and sociodemographic questionnaire. Multivariate regression analyses were conducted with p-value <0.05 as level of significance. RESULTS: The mean age was 15.3 years (SD = 1.27); 48.8% were male. The twelve-month prevalence of major depression was 11.3% and dysthymia was 1.4%. In the final regression analysis, female gender [OR = 4.3, p = 0.046], the experience of bullying [OR = 7.96, p = 0.004], difficulty getting along with friends, [OR = 7.5, p = 0.004], history of sexual abuse [OR = 8.1, p = 0.01], and perceived family dysfunction [OR = 4.9, p = 0,023] were found to be independent predictors of depressive disorders. CONCLUSION: Depressive syndromes are a significant health burden in adolescents. Being female, being bullied, having a history of sexual abuse, and family dysfunctionality are risk factors associated with depression among these population.

Prosthetic device and service satisfaction, quality of life, and functional performance in lower limb prosthesis clients.

OBJECTIVE: The aim of this study was to characterize the relationship between prosthetic device and service satisfaction, health-related quality of life (HRQOL), and functional movement in a diverse population of lower limb prosthesis users. METHODS: An online survey was conducted on individuals with lower limb amputation between September and October 2021. Sample validated questionnaires assessing demographic and clinical features, satisfaction, functional outcomes, and quality of life were analyzed using path analysis. RESULTS: Participants were 1736 individuals with lower limb amputation. Overall, 44% of participants reported dissatisfaction with prosthetic device, whereas 37% were dissatisfied with prosthetic service. Low functional mobility was reported by 58% of participants and 61% reported low HRQOL. Lower extremity functional status (ß = 0.55), HRQOL (ß = 0.08), Activities-specific Balance Scale (ß = 0.22), and modified fall efficacy scale (ß = -0.07) are significantly associated with prosthetic device satisfaction (P < 0.0005, R2 = 0.47). Satisfaction with provider service was significantly associated with lower extremity functional status (ß = 0.44) and balance confidence (ß = 0.18) (P < 0.0005, R2 = 0.34). CONCLUSION AND CLINICAL RELEVANCE: Civilians, veterans, and service members reported low functional mobility, low quality of life, and moderate levels of dissatisfaction with their lower extremity prosthetic device and provider service. Improvements in mobility, balance, quality of life, and fall efficacy may enhance device satisfaction. Functional mobility and balance improvements may increase ratings of provider service. This study provides feedback that may improve clinical decisions on lower limb prosthesis patient care.

Core and Whole-Body Vibration Exercise Improve Military Foot March Performance in Novice Trainees: A Randomized Controlled Trial.

INTRODUCTION: The purpose of the present study was to investigate core exercise training and whole-body vibration (WBV) as a training method to improve performance and recovery from an 8-km military foot march in novice trainees. MATERIALS AND METHODS: A 3 × 5 repeated measures randomized control trial was used to evaluate the effects of core exercise training and WBV on performance and recovery from an 8-km foot march. Thirty-nine participants were randomized into three groups: core exercise (Ex), WBV with core exercise (WBVEx), and control. Each participant completed two 8-km foot marches (FM1 and FM2) with a 35 pound rucksack, separated by 4 weeks. Participants in the Ex and WBVEx groups completed 3 weeks of core exercise training, three times per week in between FM1 and FM2. Performance time, creatine kinase (CK), and interleukin-6 (IL-6) were measured. The Auburn University Institutional Review Board approved all aspects of this study (protocol number: 19-211 MR 1907). RESULTS: Performance time (P < .001) and CK (P = .005) were significantly improved during FM2 as compared to FM1. The Ex (d = -0.295) and WBVEx (d = -0.645) treatments had a large effect on performance time. CK (P < .001) and IL-6 (P < .001) were significantly elevated at the completion of the foot march regardless of group. Only CK remained elevated for 2 days (P < .001) following the foot march. CONCLUSIONS: Core exercise training with or without WBV improved 8-km foot march performance time by 5-6 minutes. The improvements are likely because of an increase in trunk stability. Additionally, this study showed that completing two identical foot marches a month apart increases performance and improves recovery.

Systematic review and meta-analyses on the effects of whole-body vibration on bone health.

OBJECTIVE: To determine whole body vibration influence on human bone density and bone biomarkers. METHODS: We identified studies in Medline, Web of Science, Cumulative Index of Nursing and Allied Health, SPORTDiscus, Embase and Cochrane from inception to November 2021. Human randomized controlled trials involving commercially available whole body vibration platforms were included. Outcomes included bone density mean difference and serum concentrations of biomarkers (Procollagen type 1 N-terminal Propeptides, Osteocalcin, Bone specific alkaline phosphatase, and C-terminal Telopeptide of type 1 collagen). Random effects model (Hedges' g effect-size metric and 95% confidence-intervals) compared whole body vibration effect on bone density and bone biomarkers. Moderator analyses assessed health status, age, menopausal status, vibration type, vibration frequency, and study duration influence. RESULTS: Meta-analysis of 30 studies revealed bone density improvement after whole body vibration (Hedges' g = 0.11; p = 0.05; 95% CI = 0.00, 0.22). Whole body vibration improved bone density in healthy (Hedges' g = 0.10; p = 0.01; 95% CI = 0.02, 0.17) and postmenopausal women (Hedges' g = 0.09; p = 0.02; 95% CI = 0.01, 0.18). Bone density also increased following side-alternating whole body vibration intervention (Hedges' g = 0.21; p = 0.02; 95% CI = 0.04, 0.37). Whole body vibration had no significant effect on either bone formation biomarkers (Hedges' g = 0.22; p = 0.01; 95% CI = 0.05, 0.40) or bone resorption biomarkers (Hedges' g = 0.03; p = 0.74; 95% CI = -0.17, 0.23). CONCLUSION: Whole body vibration may be clinically useful as non-pharmacological/adjunct therapy to mitigate osteoporosis risk in healthy postmenopausal females. Additional studies are needed to determine the underlying mechanisms.

Core and Whole Body Vibration Exercise Influences Muscle Sensitivity and Posture during a Military Foot March.

Military foot marches account for 17-22% of Army musculoskeletal injuries (MSI), with low back pain (LBP) being a common complaint. Core-exercise and whole-body vibration (WBV) have been shown to decrease LBP in patients with chronic low back MSI. This study investigated if WBV and/or core-exercise influenced LBP or posture associated with a military ruck march. A randomized control trial with three groups: (1) WBV and core-exercise (WBVEx); (2) core-exercise alone (Ex); and (3) control evaluated the effects of core-exercise and WBV on LBP during/after a two 8 K foot marches with a 35 lb rucksack. The intervention groups completed three weeks of core-exercise training with/without WBV. Outcome measurements included visual analog scale (VAS), algometer, posture and electromyography (EMG). LBP, pressure threshold, and posture were elevated throughout the foot march regardless of group. LBP remained elevated for 48 h post foot march (p = 0.044). WBVEx and Ex did not have a significant effect on LBP. WBVEx and Ex both decreased muscle sensitivity and increased trunk flexion (p < 0.001) during the second foot march (FM2). The 8 K foot marches significantly increased LBP. Core-exercise training with/without WBV decreases low back muscle sensitivity. WBV and core-exercise increases trunk flexion which may help improve performance and may influence LBP.

Exertional Heat Stroke Knowledge and Management among Emergency Medical Service Providers.

This study evaluated emergency medical services (EMS) providers' knowledge of exertional heat stroke (EHS) and assessed current EMS capabilities for recognizing and managing EHS. EMS providers currently practicing in the United States were recruited to complete a 25-item questionnaire. There were 216 questionnaire responses (183 complete) representing 28 states. On average, respondents were 42.0 ± 13.0 years old, male (n = 163, 75.5%), and white (n = 176, 81.5%). Most respondents were Paramedics (n = 110, 50.9%) and had ≥16 years of experience (n = 109/214, 50.9%) working in EMS. Fifty-five percent (n = 99/180) of respondents had previously treated a patient with EHS. The average number of correct answers on the knowledge assessment was 2.6 ± 1.2 out of 7 (~37% correct). Temporal (n = 79), tympanic (n = 76), and oral (n = 68) thermometers were the most prevalent methods of temperature assessment available. Chemical cold packs (n = 164) and air conditioning (n = 134) were the most prevalent cooling methods available. Respondents demonstrated poor knowledge regarding EHS despite years of experience, and over half stating they had previously treated EHS in the field. Few EMS providers reported having access to an appropriate method of assessing or cooling a patient with EHS. Updated, evidence-based training needs to be provided and stakeholders should ensure their EMS providers have access to appropriate equipment.
