Occupational stressors and mental illness in healthcare work: An intersection between gender, race, and class.

BACKGROUND: Previous studies have supported the relevance of using broad and complex approaches, including multiple explanatory categories, to analyze mental disorders in the working population. This study aimed to assess the direct and indirect effects of gender, race, social class, and occupational stressors on mental health. METHODS: A cross-sectional study used a random sample of 3343 health workers. The effort-reward imbalance (ERI) scale measured occupational stressors. The World Health Organization Self-Reporting Questionnaire (SRQ-20) evaluated common mental disorders (CMDs) as outcomes. The role of gender, race/color, and class determinants (level of schooling and income) in the relationship between occupational stressors and CMD was assessed. Structural equation modeling was used to determine associations and effects. RESULTS: Occupational stressors were directly associated with CMD and mediated the relationship between income and CMD. Gender was directly associated with occupational stressors, income, and domestic overload. Race was associated with education and with CMD through indirect paths mediated by class indicators. Class indicators contributed to increasing exposure to occupational stressors and the occurrence of CMD. CONCLUSION: The results highlight the relevance of gender, race/color, and class in understanding the unequal distribution of work stressors and mental illness in health workers.

Stressful work in primary health care and mental health: The role of gender inequities in Brazil.

BACKGROUND: This study aims to analyze the association between occupational stressors, evaluated by the Effort-Reward Imbalance Model (ERI), and the occurrence of common mental disorders (CMD) among healthcare workers (HCW), additionally considering mediation by over-commitment from work (OW) and mediation of gender effects by work stressors. METHODS: Cross-sectional study, including a random sample of 3343 HCWs, from six municipalities of Bahia, Brazil. The ERI scale measured the occupational stressors (main exposure), and the Self-Reporting Questionnaire (SRQ-20) was used to screen for CMD. Data analysis used Structural Equation Modeling techniques to understand the relationships between gender, occupational stressors, and the occurrence of CMD. RESULTS: ERI and OW were associated with CMD. OW mediated the negative effect of ERI on the mental health of HCW. Female workers had higher levels of ERI, OW, and CMD prevalence; the total gender effect on CMD prevalence was mediated by ERI and OW. CONCLUSIONS: The findings highlight the association of work psychosocial stressors and CMD among HCW, including partial mediation by OW. Gender inequalities persisted among HCW, with women most exposed to occupational stressors and CMD. ERI and OW partially mediated the effect of gender on CMD.

Lower limb muscle strength in patients with low back pain: a systematic review and meta-analysis.

OBJECTIVE: To systematically review the published studies that compare lower limb muscle strength in patients with low back pain to matched healthy controls. METHODS: We searched Medline, SciELO, Cumulative Index to Nursing and Allied Health (CINAHL), and Scopus up until December 2017. Studies comparing lower limb muscle strength in people diagnosed with low back pain to healthy control participants were included in the systematic review. RESULTS: 14 studies, which included 951 healthy controls and 919 patients with low back pain, fulfilled the inclusion criteria. Meta-analysis revealed a lower muscle strength of hip abductor/extensors and knee extensors in patients with low back pain in comparison to healthy controls. The average strength of hip abductors (Five studies, SMD=0.7 95% CI: 0.49 to 0.9) and hip extensors (Two studies, SMD=0.93, 95% CI: 0.62 to 1.23) was significantly lower in patients with low back pain compared to that of healthy controls. Knee extensor muscle strength was significantly lower in patients with low back pain compared to healthy controls (Three studies, WMD=0.31 Nm/kg, 95% CI: 0.1 to 0.5). The meta-analysis indicated a no significant difference in knee flexor muscle strength in patients with low back pain compared to healthy controls. CONCLUSIONS: Lower limb muscle is impaired in patients with low back pain.

Effects of the FIFA 11 training program on injury prevention and performance in football players: a systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of FIFA 11 training on injury prevention and performance in football players. DESIGN AND METHODS: Systematic review and meta-analysis. We conducted a systematic search using four databases (CINAHL, Cochrane Library, EMBASE, and PubMed) to find controlled trials evaluating the effects of FIFA 11 on injury prevention and performance among football players. Weighted mean differences, standard mean differences, risk ratios, and 95% confidence intervals were calculated, and heterogeneity was assessed using the I2 test. RESULTS: We analyzed 11 trials, including 4700 participants. FIFA 11 resulted in a significant reduction in injury risk (risk ratio = 0.69; 95% confidence interval, 0.49-0.98; P = 0.02) and improvements in dynamic balance (weighted mean difference = 2.68; 95% confidence interval, 0.44-4.92; P = 0.02) and agility (standard mean difference = -0.36; 95% confidence interval, 0.70-0.02; P = 0.04). The meta-analysis indicated a non-significant improvement in jump height (standard mean difference = 0.25; 95% confidence interval, 0.08-0.59; P = 0.14) and running sprint (standard mean difference = -0.24; 95% confidence interval, 0.58-0.10; P = 0.17) in the FIFA 11 group. CONCLUSIONS: FIFA 11 can be considered as a tool to reduce the risk of injury. It may improve dynamic balance and agility and can be considered for inclusion in the training of football players.

Opportunities for translation: targeting DNA repair pathways in pancreatic cancer.

Pancreatic ductal adenocarcinoma (PDAC) remains one of the poorest prognosis neoplasms. It is typified by high levels of genomic aberrations and copy-number variation, intra-tumoural heterogeneity and resistance to conventional chemotherapy. Improved therapeutic options, ideally targeted against cancer-specific biological mechanisms, are urgently needed. Although induction of DNA damage and/or modulation of DNA damage response pathways are associated with the activity of a number of conventional PDAC chemotherapies, the effectiveness of this approach in the treatment of PDAC has not been comprehensively reviewed. Here, we review chemotherapeutic agents that have shown anti-cancer activity in PDAC and whose mechanisms of action involve modulation of DNA repair pathways. In addition, we highlight novel potential targets within these pathways based on the emerging understanding of PDAC biology and their exploitation as targets in other cancers.

Potential of Cricket (Acheta domesticus) Flour as a Lean Meat Replacer in the Development of Beef Patties.

This study examined the incorporation of cricket (Acheta domesticus) flour (CF) (0, control; 5.0%, CF5.0; 7.5%, CF7.5; and 10.0%, CF10.0) as a lean meat replacer in beef patties and its impact on composition, microbiological, sensory, and technological properties, as well as its influence on the cooking process. The inclusion of CF led to beef patties with significantly higher protein levels than the control group. Additionally, an elevation in total viable (TVC) and lactic acid bacteria (LAB) counts was observed. However, Enterobacteriaceae counts remained at safe levels. CF5.0 demonstrated similar sensory scores and purchase intention to the control treatment. CF7.5 and CF10.0 showed comparable sensory scores to the control except for texture attributes. The inclusion of CF significantly reduced cooking loss and diameter reduction values. Beef patties with CF were notably firmer and had a browner color than the control. In general, the cooking process impacted the technological properties similarly in both the control and beef patties with CF. In all cooked samples, no significant differences in pH, redness (a*), or texture were observed. This study demonstrated that incorporating up to 5.0% CF into beef patties is optimal in terms of composition, technological, sensorial, and cooking properties.

Overexpression of mTOR in Leukocytes from ALS8 Patients.

BACKGROUND: The mutated VAPBP56S (vesicle B associated membrane protein - P56S) protein has been described in a Brazilian family and classified as Amyotrophic Lateral Sclerosis type 8 (ALS8). OBJECTIVE: We aimed to study altered biochemical and immunological parameters in cells from ALS8 patients to identify possible biomarkers or therapeutic targets. METHODS: Wild-type VAPB, VAPBP56S, mTOR, proinflammatory cytokines, and oxidant/reducing levels in serum, leucocytes, and cellular lysate from ALS8 patients and health Controls were performed by ELISA, fluorimetry, and spectrophotometry. RESULTS: Our results showed similar levels of mutant and wild-type VAPB in serum and intracellular lysate (p > 0.05) when ALS8 patients and Controls were compared. IL-1ß, IL-6, and IL-18 levels in patients and Controls showed no difference, suggesting an absence of peripheral inflammation (p > 0.05). Oxidative metabolic response, assessed by mitochondrial ROS production, and reductive response by MTT reduction, were higher in the ALS8 group compared to Controls (p < 0.05), although not characterizing typical oxidative stress in ALS8 patients. Total mTOR levels (phosphorylated or non-phosphorylated) of ALS8 patients were significantly lower in serum and higher in intracellular lysate than the mean equivalents in Controls (p < 0.05). A similar result was observed when we quantified the phosphorylated protein (p < 0.05). CONCLUSION: We demonstrate the possibility of using these biochemical and immunological parameters as potential therapeutic targets or biomarkers. Furthermore, by hypothesis, we suggest a hormetic response in which both VAPB forms could coexist in different proportions throughout life. The mutated VAPBP56S production would increase with aging and predominate over the wild-type VAPB levels, determining the onset of symptoms and aggravating the disease.

Occupational stress and common mental disorders: how do coping strategies work?

Introduction: Coping strategies are described as devices capable of minimizing the effects of occupational stress on workers' mental health. Objectives: To evaluate the association between occupational stressors and occurrence of common mental disorders and how coping strategies work in this relationship. Methods: This is a cross-sectional study with 3,343 healthcare workers from six municipalities in the state of Bahia, Brazil. Common mental disorders were measured by the Self-Reporting Questionnaire, and occupational stressors by the Job Content Questionnaire. Coping strategies included physical activity, leisure activities, social support at work, alcohol consumption, and smoking. Bivariate and multivariate analyses were performed, stratified by sex. Results: Occupational stressors were associated with common mental disorders, more strongly among women. The practice of physical activity contributed to reduce the prevalence of common mental disorders, regardless of occupational stressors. Leisure activities were associated with lower prevalence of common mental disorders, but without statistical significance, losing relevance in the presence of occupational stressors. Social support and smoking or drinking habits were not associated with common mental disorders and did not influence the relationship with occupational stressors. Conclusions: Occupational stressors are associated with common mental disorders, with emphasis on high demand, even after adjusted for coping strategies. The relationship between occupational stressors and mental is corroborated, with greater female vulnerability, as well as the role of positive coping strategies in protecting mental health. The pertinence of adopting measures that reduce stress at work, promote the adoption of positive coping strategies, and consider gender inequalities in these relationships.

Neuroendoscopic Approach of a Massive Bilateral Chronic Subdural Hematoma in a Child Using a Single Burr Hole.

There are several treatment modalities for the management of subdural fluid collection in infants, such as fontanelle puncture and drainage, burr hole irrigation, and subduroperitoneal shunt. This report describes the case of a girl born with congenital neurological impairment due to severe injury of the brain with unknown etiology. At five months of age, she suffered from head trauma and developed somnolence after three days and was diagnosed with a bilateral massive chronic subdural hematoma. Normal fundoscopy did not confirm the non-accidental head trauma. Neuroendoscopy using a single burr hole was performed and complete drainage was achieved. Arachnoid tearing was observed during the procedure. Postoperatively, the patient showed clinical improvement, and brain expansion was observed after one month. The main advantages of neuroendoscopy for bilateral massive chronic subdural hematoma are accurate visualization of the space, minimal invasiveness, and treatment of both sides with reliable drainage control.

Tethered Cord Syndrome After Myelomeningocele Repair: A Literature Update.

Tethered cord syndrome (TCS) after myelomeningocele (MMC) repair (or secondary TCS) is a challenging condition characterized by neurological, orthopedic, and urological symptoms, which are combined with a low-lying position of the conus medullaris and damage to the stretched spinal cord owing to metabolic and vascular derangements. It has been reported that this syndrome affects, on average, 30% of children with MMC. In this review, we revisit the historical aspects of secondary TCS and highlight the most important concepts of diagnosis, treatment, and outcomes for secondary TCS as well as the current research regarding the impact of fetal MMC repair in the incidence and management of TCS. In the future, the development of synthetic models of TCS could shorten the learning curve of pediatric neurosurgeons, and research into the cellular proapoptotic features and increased inflammation biomarkers associated with TCS will also improve the treatment of this condition and minimize retethering of the spinal cord.
