Health promotion, disease prevention and periodic health checks: perceptions and practice among family physicians in eastern Mediterranean region

Introduction: The aim of this study was to identify the current practices and perceptions of family physicians regarding health promotion, disease prevention including periodic screening and health checks in Eastern Mediterranean Region. Methods: A multi-country cross-sectional study was conducted in six countries of EMR, from September 2014 to March 2015. Family Physicians who were currently practicing in different countries of EMR were invited to participate in the study through email. A pre-tested structured questionnaire was used for data collection. Data was entered and analyzed on SPSS 19 and logistic regression analysis was performed. Results: A total of 100 physicians data was included in the final analysis. The majority were female physicians (76%): 63% were 25 to 35 years of age. Approximately 53% of Family physicians always recommend periodic screening and health checks to their patients. The common screening question asked to patients in medical history was related to their blood pressure (86%). Almost all (99%) of the Family physicians believe they should conduct periodic health checks. Those who had postgraduate training in Family Medicine (OR: 0.5; 95% CI: 0.39-1.67) and attended CME sessions regularly (OR: 0.11; 95% CI: 0.01-0.93), are more likely to recommend periodic screening and health checks to their patients. Conclusion: Periodic screening and health check is an important strategy to prevent disease and maintain health. It is an underutilized practice and a great need exists for its implementation in family practice

Toll-like receptor-2 deficiency enhances non-alcoholic steatohepatitis

<p>Abstract</p> <p>Background</p> <p>Previously we reported that mice deficient in toll-like receptor 4 (TLR-4) signalling were protected from diet-induced non-alcoholic steatohepatitis (NASH). Another member of the toll-like receptor family, TLR-2, has been shown to play a role in lipid trafficking via uptake of diacylated lipoproteins. However, a role for TLR-2 in NASH has not been elucidated. The objectives of the current study were to examine the influence of dietary fat quality and TLR-2 on NASH pathogenesis.</p> <p>Methods</p> <p>Steatohepatitis was induced in male Db, C57BL/6 and TLR-2^-/-mice by feeding an L-amino acid-defined diet that was deficient in methionine and choline (MCDD). Mice fed the base diet supplemented with methionine and choline (control diet; CD) were used as controls. To determine the role of fat quality, MCDD was enriched with polyunsaturated corn oil (PUFA) or coconut oil that is comprised mostly of saturated fat (SAFA); the total amount of each fat was 112.9 g/kg of diet. After 8 weeks of feeding CD or MCDD, hepatic steatosis, inflammation and necrosis were evaluated in histological sections. Total RNA was extracted from frozen liver samples and mRNA expression of TNFα, collagen α1, IL-10, peroxisome proliferator-activated receptor-γ (PPAR-γ), TLR-4, and CD14, was analyzed via real-time PCR. Protein levels of TLR-2 were analyzed by western blot.</p> <p>Results</p> <p>Panlobular macrovessicular steatosis and diffuse leukocyte infiltration were noted in PUFA-fed Db mice. Histological scores demonstrated significantly less steatosis, inflammation and necrosis in SAFA-fed mice of all mouse strains. However, compared to wild type mice, hepatocellular damage was notably more severe in TLR-2^-/-mice. Consistent with histological findings, mRNA expression of TNFα was elevated by approximately 3-fold in TLR-2^-/-mice; PPAR-γ expression was blunted in this strain compared to wild type. Expression of the matrix protein collagen αI was also significantly higher in TLR-2^-/-mice, indicating a pro-fibrogenic state. Sensitivity to steatohepatitis due to dietary fat or TLR-2 deficiency correlated significantly with alterations in the expression of TLR-4 as well as the co-receptor CD-14.</p> <p>Conclusions</p> <p>Our findings suggest that dietary saturated fat plays a protective role against MCDD-induced steatohepatitis, whereas TLR-2 deficiency exacerbated NASH. The mechanism underlying the response to dietary fat and TLR-2 likely involves altered signalling via the TLR-4 pathway.</p

Two cultures, one identity: formulations of Australian Isma'ili Muslim identity

The Shi'a Imami Nizari Isma'ili Muslims have often been considered the "poster child" for pluralistic integration (Cayo 2008). This ethos has been inculcated within members of the community, with its adherents seeing themselves as a diverse and multi-ethnic collective. Nevertheless, despite this purported pluralism, social research on the Isma'ilis has primarily focused on the diasporic and post-diasporic migrant communities of South Asian descent, the 'first and second-generation immigrants,' in the Euro-American context (Mukadam and Mawani 2006, 2009; Nanji 1983, 1986). The experiences of co-religionists in other contexts have often been neglected. This study examines how members of the self-described geographically and socially isolated Isma'ili community in Australia construct their identity vis-à-vis the larger, global, Isma'ili community, and how they have responded to the potential of identity threat given the arrival of another group of Isma’ilis with a differing migratory history integrating into the extant community. Using the approach of identity process theory, this study examines how salient features of identity are constructed amongst the Australian Isma'ilis, how religion and identity take on multiple meanings within the Australian Isma'ili context, and, finally, sheds light on the self-sufficiency of this community despite geographic and social isolation

New leadership model for family physicians in the Eastern Mediterranean region: a pilot study across selected countries

Background: Family Medicine is growing rapidly across the Eastern Mediterranean Region. However, it needs support in terms of overall health system development. This will require strong leadership in family medicine to implement the change required to improve current conditions. Objective: To collect data that will support the development of a leadership program for the future family physicians in the region. Methods: A cross-sectional study was conducted from July 2016 to September 2016 in eight countries of the Eastern Mediterranean Region, (Bahrain, Egypt, Iraq, Jordan, Kuwait, Qatar, Pakistan, and Saudi Arabia). These countries were selected to obtain perceptions of Family Physicians (FPs) regarding the current leadership model and to explore the need for a new future innovative model in Family Medicine (FM) across the region. Results: The information of 68 family physicians was included in the final analysis. The majority of the FPs was females as compared to males (71% vs. 29%). Forty-four percent of the FPs had 10 to 19 years of experience. Almost all of the FPs (96%) had completed some training in family medicine after graduation. About three fifths of the FPs had completed postgraduate qualifications and out of those, 64% had passed Board or Membership Examinations. Twenty-one percent of them are currently in a leadership role and 45% who were not in any leadership role responded that the current situation of FM in their country is poor. All of the leaders believed that it is important to develop strong leadership in FM to take the specialty forward. Almost similar proportions (67% and 64%) of leaders and non-leaders thought that establishing regional associations would enhance the FM practice model. Approximately two thirds of leaders (67%) responded that the current role of decision makers in the Ministry of Health (MOH) regarding capacity building in FM is not effective. The majority of the FPs (54% and 38%) considers that the existing postgraduate curriculum does not address leadership skill development in FM. Eighty-eight percent of the FPs both from leadership and non-leadership groups agreed that academic institutions and practicing FPs can play an effective leadership role in taking FM forward. Conclusion: The Family Medicine specialty will have to develop leadership capabilities in line with today’s fast-moving changes in healthcare for it to obtain the due recognition in the healthcare delivery system

Galectin-9 Controls CD40 Signaling through a Tim-3 Independent Mechanism and Redirects the Cytokine Profile of Pathogenic T Cells in Autoimmunity

While it has long been understood that CD40 plays a critical role in the etiology of autoimmunity, glycobiology is emerging as an important contributor. CD40 signaling is also gaining further interest in transplantation and cancer therapies. Work on CD40 signaling has focused on signaling outcomes and blocking of its ligand, CD154, while little is known about the actual receptor itself and its control. We demonstrated that CD40 is in fact several receptors occurring as constellations of differentially glycosylated forms of the protein that can sometimes form hybrid receptors with other proteins. An enticing area of autoimmunity is differential glycosylation of immune molecules leading to altered signaling. Galectins interact with carbohydrates on proteins to effect such signaling alterations. Studying autoimmune prone NOD and non-autoimmune BALB/c mice, here we reveal that in-vivo CD40 signals alter the glycosylation status of non-autoimmune derived CD4 T cells to resemble that of autoimmune derived CD4 T cells. Galectin-9 interacts with CD40 and, at higher concentrations, prevents CD40 induced proliferative responses of CD4loCD40+ effector T cells and induces cell death through a Tim-3 independent mechanism. Interestingly, galectin-9, at lower concentrations, alters the surface expression of CD3, CD4, and TCR, regulating access to those molecules and thereby redirects the inflammatory cytokine phenotype and CD3 induced proliferation of autoimmune CD4loCD40+ T cells. Understanding the dynamics of the CD40 receptor(s) and the impact of glycosylation status in immunity will gain insight into how to maintain useful CD40 signals while shutting down detrimental ones

Neonatal Androgenization Exacerbates Alcohol-Induced Liver Injury in Adult Rats, an Effect Abrogated by Estrogen

Alcoholic liver disease (ALD) affects millions of people worldwide and is a major cause of morbidity and mortality. However, fewer than 10% of heavy drinkers progress to later stages of injury, suggesting other factors in ALD development, including environmental exposures and genetics. Females display greater susceptibility to the early damaging effects of ethanol. Estrogen (E2) and ethanol metabolizing enzymes (cytochrome P450, CYP450) are implicated in sex differences of ALD. Sex steroid hormones are developmentally regulated by the hypothalamic-pituitary-gonadal (HPG) axis, which controls sex-specific cycling of gonadal steroid production and expression of hepatic enzymes. The aim of this study was to determine if early postnatal inhibition of adult cyclic E2 alters ethanol metabolizing enzyme expression contributing to the development of ALD in adulthood. An androgenized rat model was used to inhibit cyclic E2 production. Control females (Ctrl), androgenized females (Andro) and Andro females with E2 implants were administered either an ethanol or isocalorically-matched control Lieber-DeCarli diet for four weeks and liver injury and CYP450 expression assessed. Androgenization exacerbated the deleterious effects of ethanol demonstrated by increased steatosis, lipid peroxidation, profibrotic gene expression and decreased antioxidant defenses compared to Ctrl. Additionally, CYP2E1 expression was down-regulated in Andro animals on both diets. No change was observed in CYP1A2 protein expression. Further, continuous exogenous administration of E2 to Andro in adulthood attenuated these effects, suggesting that E2 has protective effects in the androgenized animal. Therefore, early postnatal inhibition of cyclic E2 modulates development and progression of ALD in adulthood
