Synergistic action of vitamin D3 and A on motor activity regulation in mice model of extrapyramidal syndrome: Correlational insights into astrocyte regulation, cytokine modulation, and dopaminergic activity.

BACKGROUND: Extrapyramidal syndromes (EPS) represent neurological side effects of antipsychotic medications, characterized by motor disturbances. While previous studies have indicated the neuroprotective effects of vitamin D and A against EPS, the underlying mechanisms of this protection remain unclear. METHODS: Twenty-four adult mice were categorized into four groups: positive and negative control groups, one receiving a dopamine antagonist, and the other receiving both a dopamine antagonist and vitamins D and A. Sections of the corticobasal loop, specifically the motor cortex (M1) and basal nuclei (CPu), were prepared for Immunohistochemistry (IHC) and stained with Glial Fibrillary Acidic Protein (GFAP) to visualize reactive astrocytes. ELISA assays for TNF-α, IL-6, IL-4, IL-13, and dopamine levels were performed on homogenized brain sections. RESULTS: The EPS group exhibited a significant increase in TNF-α and IL-6 levels in M1 and CPu. Treatment with dopamine agonists and vitamin D&A resulted in significant reductions in IL-6 levels. Only the Vitamin D&A group showed a significant decline in TNF-α. The EPS group recorded significant decreases in IL-4 and IL-13, with IL-13 significantly elevated in the dopamine agonist and Vitamin D&A groups. IL-4 was notably increased in the Vitamin D&A groups. Dopamine concentration significantly declined in the EPS group, with improvements observed in the groups treated with dopamine agonists, and vitamin D&A. Reactive astrocytes were significantly expressed in the M1 and CPu of the EPS group but poorly expressed in other groups. CONCLUSIONS: EPS is linked to astrocyte activation, an upsurge in pro-inflammatory cytokines, a decline in anti-inflammatory cytokines, and dopamine in the corticobasal loop. Administration of vitamin D3 and A was found to suppres pro-inflammatory cytokines and repress anti-inflammatory cytokines associated with astrocyte activation.

Determination of hand grip strength and its correlates during pregnancy: a cross-sectional study.

BACKGROUND: Pregnancy results in many changes, including reduced hand grip strength (HGS). However, good HGS is required for physical functions such as carrying and breastfeeding the baby after birth. The aim of this study was to determine the factors that may predict HGS during pregnancy. METHODS: The study was a cross-sectional study approved by the Research Ethics Committees of Kano State Ministry of Health and Aminu Kano Teaching Hospital in Kano, north-west, Nigeria. Pregnant women at the designated hospitals were included in the study if they had no serious comorbidities or any known neurological condition that affects the hands and the neck. Demographic characteristics and independent (predictor) variables (age, weight, height, BMI, maternity leave status, number of full-term deliveries, number of preterm deliveries, number of live births, number of abortuses, gravidity, trimester, systolic blood pressure, diastolic blood pressure, inter arm systolic BP difference [IASBP], inter arm diastolic BP difference [IADBP], and heart rate) of each of the participants were recorded by experienced therapists. The data were analysed using descriptive statistics, t-test, Pearson correlation coefficient and standard multiple regression. RESULT: One hundred and sixty-one pregnant women with mean age, 25.04 ± 4.83 years participated in the study. In the dominant hand, 120 participants (74.5%) had weak grip strength. In the non-dominant hand, 135 participants (83.9%) had weak grip strength. For the dominant hand, the total variance explained by the whole model was significant, 28.5%, F(11, 161) = 1.187, R2 = 0.081, p = 0.300 . In the final model, none of the variables significantly predicted HGS. However, systolic blood pressure contributed to the model more than any other variable (Beta = -0.155). For the non-dominant hand, the total variance explained by the whole model was not significant, 33.1%, F(11, 161) = 1.675, R2 = 0.111, p = 0.089 . In the final model, only systolic blood pressure (Beta = -0.254, p = 0.023) significantly predicted hand grip strength. CONCLUSION: Cardiovascular events or changes during pregnancy (such as change in systolic blood pressure) may be related to HGS in pregnant women. It is therefore, important for clinicians to pay attention to this, in planning rehabilitation strategies for pregnant women.

Effect of Paula exercise method on functional outcomes of women with post fistula repair incontinence: a protocol for randomized controlled trial.

BACKGROUND: Post-fistula-repair incontinence (PFRI) is a common complication of vesicovaginal fistula (VVF) surgeries. It entails continuous leakage of urine after successful VVF closure. Pelvic Floor Muscle Training (PFMT) plays a vital role in the management of PFRI, however, an evolving exercise approach is the Paula Exercise Method (PEM) which has shown a promising effect in stopping urinary incontinence, but there is no data on its effect on PFRI. This study therefore, proposes to primarily investigate the effect of PEM on urine leakage and secondarily, pelvic floor strength (PFS), quality of life (QoL), sexual function (SF), and mental health (MH) in women with PFRI. METHODS: This is a study protocol for a randomized controlled trial. A total of 182 participants are expected to participate in the study after satisfying the inclusion criteria. The participants will be randomized into either PEM or PFMT study groups. The demographic data of all the participants will be recorded. Each participant will be assessed for urine leakage, PFS, QoL, SF, and MH at baseline and subsequently, at four, eight and 12 weeks of intervention. Demographic parameters will be summarized using descriptive statistics. Continuous data will be computed for differences using inferential statistic of Analysis of variance, t-test and Man Whitney U as appropriate. All analyses will be performed using SPSS version 22.0 with probability set at 0.05 alpha level. DISCUSSION: It is hoped that the outcome of this study will determine the effect of the Paula exercise method on urine leakage, pelvic floor strength, quality of life, sexual function, and mental health among women with post-fistula-repair incontinence and also provide evidence for the use of the Paula method in urinary incontinence.

Perceived social support and social constraints in Hausa women stroke survivors: A cross-sectional study.

Background: Social factors modulating stroke outcomes are found to be culturally and gender inclined. We examined social support and social constraints in Hausa women stroke survivors.Aim: To determine social support and social constraints in Hausa women after stroke.Materials and methods: Seventy-four (74) Hausa women stroke survivors were conveniently recruited from three tertiary health centers to participate in this cross-sectional study. Sociodemographic and stroke-related attributes of the participants were obtained. Perceived social support and social constraints were assessed using multidimentional scale of perceived social support (MSPSS) and the social problem questionnaire (SPQ), respectively. The relationship and association between different variables were assessed using Pearson's correlation and chi-square test, respectively.Results: Majority of the participants (60.8%) reported adequate level of social support. Similarly, most participants reported fairly low level of social constraints in total family stress (91.9%) and nonchild-related stress (90.5%). None of the participants' sociodemographic features had a significant relationship with either social support or social constraints (p > .05). Findings indicated an inverse relationship between social support and social constraint.Conclusion: Findings of this study suggest that adequate social support potentially limits the level of social constraint encountered by women who suffered stroke. The Hausa culture seems to be impressive in characteristically demonstrating high level of social support as found in this study. It is recommended that physiotherapist should assist by providing educative programs that would increase caregiver's knowledge of social support and how to develop it and cultural values that emphasize positive social interaction should be encouraged.

Factors predicting community participation in patients living with stroke, in the Western Cape, South Africa.

Purpose: An important focus of poststroke rehabilitation is the attainment of community participation. However, several factors may influence participation some of which vary from setting to setting. The aim of this study is to investigate the factors influencing community participation among community-dwelling stroke survivors in the Western Cape, South Africa. Materials and methods: The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) and the Social Support Questionnaire 6 (SSQ6) were the instruments used to collect data. Participant demographics, clinical features and domain-specific scores of the WHODAS 2.0 were used as potential predictors. Correlation analysis and multiple regression models were used to examine determinants of community participation. All assessments were conducted using face-to-face interviews. Results: One hundred and six stroke survivors enrolled in this cross-sectional study. Risk factors, cognition, mobility, self-care, getting along with people, household activities and total WHODAS 2.0 score were associated with participation. Four predictors of community participation were identified from multiple regression, namely mobility (38%), cognition (11%), life activities (4%) and stroke risk factors (1%). Determinants varied by gender and age group. Mobility predominated in males and younger adults, while cognition was more pronounced in females and the elderly. Lastly, the influence of social support on community participation was largely defined by the gender and age of stroke survivors. Conclusion: The findings suggest focusing stroke rehabilitation on important factors such as mobility, cognition, life activities and risk factors to advance patients' participation. It also emphasizes giving specific consideration to key factors specific for gender and age of stroke survivors. Implications for Rehabilitation Community participation in the general population of stroke survivors' is largely determined by their mobility function. Determinants of community participation among stroke survivors essentially vary according to age and gender. Clinically, this study suggests that focusing on specific determinants of improved community participation according to stroke patients' demographic categories (gender and age) may be an important impetus to enhance rehabilitation outcome.
