The experiences of family caregivers of people with severe mental illness in the Middle East: A systematic review and meta-synthesis of qualitative data

BACKGROUND: There is a wealth of literature exploring the experiences of family caregivers of people with severe mental illness (SMI) in western countries, however, this topic has been neglected in the Middle East, despite families being the main source of caregiving in this context. The purpose of this review was to conduct a systematic review and qualitative meta-synthesis to explore the experiences of family caregivers living in countries in the Middle East caring for a relative with severe mental illness. METHODS: A systematic review and meta-synthesis were conducted, to comprehensively gain a thorough and detailed overview of what is known about family caregivers' experiences from published qualitative research in the Middle East geographical area from inception to May 2021. The review protocol was pre-registered with PROSPERO (Ref: CRD42020165519). RESULTS: The review identified twelve qualitative studies that explored caregivers' experiences of caring for relatives with SMI in Middle East countries. Family caregivers' experiences were captured under seven overarching themes. The participants across all studies reported negative consequences of providing care, increased burden and emotional distress. Many experienced issues with family/marital relationships and stigmatizing attitudes and behaviours from their communities. Caregivers expressed the need for increased support which was perceived to have a critical role in improving family caregivers' experiences. CONCLUSIONS: The meta-synthesis revealed many challenges and issues that affect caregivers of people with SMI in the Middle East. Family caregivers experienced distress and burden, and reported significant impact on their psychological well-being. Their experiences highlight the urgent need to provide more support for family caregivers in Middle East countries

Rapid identification of mutations in GJC2 in primary lymphoedema using whole exome sequencing combined with linkage analysis with delineation of the phenotype.

Background: Primary lymphoedema describes a chronic, frequently progressive, failure of lymphatic drainage. This disorder is frequently genetic in origin, and a multigenerational family in which eight individuals developed postnatal lymphoedema of all four limbs was ascertained from the joint Lymphoedema/Genetic clinic at St George's Hospital. Methods: Linkage analysis was used to determine a locus, and exome sequencing was employed to look for causative variants. Results: Linkage analysis revealed cosegregation of a 16.1 Mb haplotype on chromosome 1q42 that contained 173 known or predicted genes. Whole exome sequencing in a single affected individual was undertaken, and the search for the causative variant was focused to within the linkage interval. This approach revealed two novel non-synonymous single nucleotide substitutions within the chromosome 1 locus, in NVL and GJC2. NVL and GJC2 were sequenced in an additional cohort of individuals with a similar phenotype and non-synonymous variants were found in GJC2 in four additional families. Conclusion: This report demonstrates the power of exome sequencing efficiently applied to a traditional positional cloning pipeline in disease gene discovery, and suggests that the phenotype produced by GJC2 mutations is predominantly one of 4 limb lymphoedema

Scaling up proven public health interventions through a locally owned and sustained leadership development programme in rural Upper Egypt

<p>Abstract</p> <p>Introduction</p> <p>In 2002, the Egypt Ministry of Health and Population faced the challenge of improving access to and quality of services in rural Upper Egypt in the face of low morale among health workers and managers.</p> <p>From 1992 to 2000, the Ministry, with donor support, had succeeded in reducing the nationwide maternal mortality rate by 52%. Nevertheless, a gap remained between urban and rural areas.</p> <p>Case description</p> <p>In 2002, the Ministry, with funding from the United States Agency for International Development and assistance from Management Sciences for Health, introduced a Leadership Development Programme (LDP) in Aswan Governorate. The programme aimed to improve health services in three districts by increasing managers' ability to create high performing teams and lead them to achieve results.</p> <p>The programme introduced leadership and management practices and a methodology for identifying and addressing service delivery challenges. Ten teams of health workers participated.</p> <p>Discussion and evaluation</p> <p>In 2003, after participation in the LDP, the districts of Aswan, Daraw and Kom Ombo increased the number of new family planning visits by 36%, 68% and 20%, respectively. The number of prenatal and postpartum visits also rose.</p> <p>After the United States funding ended, local doctors and nurses scaled up the programme to 184 health care facilities (training more than 1000 health workers). From 2005 to 2007, the Leadership Development Programme participants in Aswan Governorate focused on reducing the maternal mortality rate as their annual goal. They reduced it from 85.0 per 100,000 live births to 35.5 per 100,000. The reduction in maternal mortality rate was much greater than in similar governorates in Egypt. Managers and teams across Aswan demonstrated their ability to scale up effective public health interventions though their increased commitment and ownership of service challenges.</p> <p>Conclusions</p> <p>When teams learn and apply empowering leadership and management practices, they can transform the way they work together and develop their own solutions to complex public health challenges. Committed health teams can use local resources to scale up effective public health interventions.</p

Forecasting Tunisian type 2 diabetes prevalence to 2027: validation of a simple model.

BACKGROUND: Most projections of type 2 diabetes (T2D) prevalence are simply based on demographic change (i.e. ageing). We developed a model to predict future trends in T2D prevalence in Tunisia, explicitly taking into account trends in major risk factors (obesity and smoking). This could improve assessment of policy options for prevention and health service planning. METHODS: The IMPACT T2D model uses a Markov approach to integrate population, obesity and smoking trends to estimate future T2D prevalence. We developed a model for the Tunisian population from 1997 to 2027, and validated the model outputs by comparing with a subsequent T2D prevalence survey conducted in 2005. RESULTS: The model estimated that the prevalence of T2D among Tunisians aged over 25 years was 12.0% in 1997 (95% confidence intervals 9.6%-14.4%), increasing to 15.1% (12.5%-17.4%) in 2005. Between 1997 and 2005, observed prevalence in men increased from 13.5% to 16.1% and in women from 12.9% to 14.1%. The model forecast for a dramatic rise in prevalence by 2027 (26.6% overall, 28.6% in men and 24.7% in women). However, if obesity prevalence declined by 20% in the 10 years from 2013, and if smoking decreased by 20% over 10 years from 2009, a 3.3% reduction in T2D prevalence could be achieved in 2027 (2.5% in men and 4.1% in women). CONCLUSIONS: This innovative model provides a reasonably close estimate of T2D prevalence for Tunisia over the 1997-2027 period. Diabetes burden is now a significant public health challenge. Our model predicts that this burden will increase significantly in the next two decades. Tackling obesity, smoking and other T2D risk factors thus needs urgent action. Tunisian decision makers have therefore defined two strategies: obesity reduction and tobacco control. Responses will be evaluated in future population surveys

Medical students' perceptions of complementary and alternative medicine therapies: A pre- and post-exposure survey in Majmaah University, Saudi Arabia

Background: Evidently, Complementary and Alternative Medicine (CAM) is increasingly a recognized medical practice that efficiently uses multiple treatment therapies and techniques in promoting the health  and wellbeing of people as well as preventing and managing a variety of human disorders. Research in CAM, which courses exposure to diverse healthcare professionals, is important from many perspectives including improvement in teaching skills of faculty, enhancing capacity building, and  innovative curriculum development. This pre- and post-design crosssectional study aimed to assess perceptions, training needs, personal usage, use in office practice, and knowledge of two batches of medical students toward CAM therapies in Majmaah University, Saudi Arabia.Materials and Methods: The second year medical students of the first (year 2012-13) and second (year 2013-2014) batch [n=26 &amp; 39, respectively] were selected for this study. A reliable 16-item  self-administered questionnaire was distributed among all students for answering before and after the 48-hour specific 19 CAM therapies course, in terms of CAM therapies are clearly conventional or  alternative, training needs, effectiveness, personal use, use in practice, management of two clinical cases by CAM or conventional therapies, and views about which evidence based approach strongly support individual CAM modalities.Results: Medical students' knowledge and perceptions of CAM therapies significantly improved across some sub-items of CAM questionnaire with a positive trend in the rest of its items including their views about CAM therapies, need for further training, personal use of therapies and advising patients regarding CAM practices strongly supported by randomized clinical controlled trials and published case studies.Conclusion: CAM course tends to have positive impact on the knowledge and perceptions of medical students, in addition to need for further training, and personal use and use of CAM therapies in practice in line with strong evidence-based data regarding therapeutic efficacy. The preliminary results of this study call for further research in specific CAM modalities with a larger sample in academic settings across the nation.

Design of experiments to study the impact of process parameters on droplet size and development of non-invasive imaging techniques in tablet coating

Atomisation of an aqueous solution for tablet film coating is a complex process with multiple factors determining droplet formation and properties. The importance of droplet size for an efficient process and a high quality final product has been noted in the literature, with smaller droplets reported to produce smoother, more homogenous coatings whilst simultaneously avoiding the risk of damage through over-wetting of the tablet core. In this work the effect of droplet size on tablet film coat characteristics was investigated using X-ray microcomputed tomography (XμCT) and confocal laser scanning microscopy (CLSM). A quality by design approach utilising design of experiments (DOE) was used to optimise the conditions necessary for production of droplets at a small (20 μm) and large (70 μm) droplet size. Droplet size distribution was measured using real-time laser diffraction and the volume median diameter taken as a response. DOE yielded information on the relationship three critical process parameters: pump rate, atomisation pressure and coating-polymer concentration, had upon droplet size. The model generated was robust, scoring highly for model fit (R2 = 0.977), predictability (Q2 = 0.837), validity and reproducibility. Modelling confirmed that all parameters had either a linear or quadratic effect on droplet size and revealed an interaction between pump rate and atomisation pressure. Fluidised bed coating of tablet cores was performed with either small or large droplets followed by CLSM and XμCT imaging. Addition of commonly used contrast materials to the coating solution improved visualisation of the coating by XμCT, showing the coat as a discrete section of the overall tablet. Imaging provided qualitative and quantitative evidence revealing that smaller droplets formed thinner, more uniform and less porous film coats
