Exploratory study into awareness of heart disease and health care seeking behavior among Emirati women (UAE) - Cross sectional descriptive study.

BACKGROUND: Cardiovascular disease was the leading cause of death among women in the United Arab Emirates (UAE) in 2010. Heart attacks usually happen in older women thus symptoms of heart disease may be masked by symptoms of chronic diseases, which could explain the delay in seeking health care and higher mortality following an ischaemic episode among women. This study seeks to a) highlight the awareness of heart diseases among Emirati women and b) to understand Emirati women's health care seeking behaviour in UAE. METHOD: A cross sectional, descriptive study was conducted using a survey instrument adapted from the American Heart Association National survey. A convenience sample of 676 Emirati women between the ages of 18-55 years completed the questionnaire. RESULTS: The study showed low levels of awareness of heart disease and associated risk factors in Emirati women; only 19.4% participants were found to be aware of heart diseases. Awareness levels were highest in Dubai (OR 2.18, p < 0.05) among all the other emirates and in the 18-45 years age group (OR 2.74, p < 0.05). Despite low awareness levels, women paradoxically perceived themselves to be self-efficacious in seeking health care. Interestingly, just 49.1% Emirati women believed that good quality and affordable health care was available in the UAE. Only 28.8% of the participants believed there were sufficient female doctors to respond to health needs of women in UAE. Furthermore, only 36.7% Emirati women chose to be treated in the UAE over treatment in other countries. CONCLUSION: Emirati women clearly lack the knowledge on severity and vulnerability to heart disease in the region that is essential to improve cardiovascular related health outcomes. This study has identified the need for wider outreach that focuses on gender and age specific awareness on heart disease risks and symptoms. The study has also highlighted potential modifiable barriers in seeking health care that should be overcome to reduce morbidity and mortality due to heart disease among national women of UAE.

Effects of bomb blast injury on the ears: The Aga Khan University Hospital experience.

OBJECTIVE: To evaluate the frequency and effects of blast-related otologic injuries. METHODS: his retrospective study was conducted at the Aga Khan University Hospital, Karachi, and comprised charts of patients who were victims of bomb explosions between January 2011 and July 2013. Frequency and percentages were reported using cross tabulation with size of bomb, distance of person from blast and the presence of victim in open or closed space. Association of associated variables were also analysed. RESULTS: Of the 100 patients, 81(81%) were men and 19(19%) were women. Besides, 68(68%) patients were aged <30 years. Also, 78(78%) subjects were exposed to < 80kg of explosives and 68(68%) were at a distance of>10m. Furthermore, 61(61%) patients were exposed to explosion in openspace. The prevalence of ear injuries was 21(21%). The odds of experiencing various symptoms of ears was high in those who were exposed to >80 kg of explosives (odds ratio: 3.38; 95% confidence interval, 1.16, 9.91). The odds of hearing loss in those who were within 10m was 8.62 (95% confidence interval: 2.72, 27.28) times than those who were >10 m from the site of explosion. CONCLUSIONS: Otologic injuries were frequently associated with large blasts.

Colostrum and mature breast milk analysis of serum irisin and sterol regulatory element-binding proteins-1c in gestational diabetes mellitus.

Background: We aimed to evaluate irisin and SREBP-1c levels in serum, colostrum and mature breast milk in women with and without gestational diabetes (GDM); and to relate them with maternal glucose, lipid profile and weight status of babies. Methods: GDM positive women (n = 33) and normal glucose tolerant women (NGT) (n = 33) were recruited. Maternal blood samples were collected at 28th week of gestation and later at 6-week post-partum while breast milk samples of the lactating mothers were collected within 72 hours of birth (colostrum) and at 6 weeks post-partum (mature milk). Irisin and SREBP-1c levels were analyzed by commercially available ELISA kits for all maternal samples. Results: Lower levels of irisin were seen in serum, colostrum and mature breast milk of GDM females (p < .01). SREBP-1c profile showed a similar trend of low serum levels in GDM, however, they were undetectable in colostrum and mature breast milk. Weak to moderate correlations of serum irisin with BMI (r = 0.439; p < .001), GTT 0 hours (r = 0.403; p = .01), HbA1c (r = -0.312; p = .011), Fasting blood glucose (r = 0.992; p = .008), and baby weight at birth (r = 0.486; p < .001). Colostrum and mature breast milk irisin showed positive associations with baby weight at 6 weeks (r = 0.325; p = .017; r = 0.296; p = .022, respectively). Serum SREBP-1c at 6 weeks correlated with random blood glucose (r = 0.318; p = .009), and HbA1c (r= -0.292; p = .011). All correlations were lost once we adjusted for maternal BMI. Conclusions: Low irisin and SREBP1-c levels may favor development of GDM in pregnant subjects. Further, low mature breast milk levels may act as a continued stressor from fetal to infant life as long as breast-feeding is continued. Further studies are required to identify the mechanistic relationship between these biomarkers and GDM.

A Functional Polymorphism (rs6265, G>A) of Brain-Derived Neurotrophic Factor Gene and Breast Cancer: An Association Study.

PURPOSE: The objective of this study was to evaluate the relationship between brain-derived neurotrophic factor (BDNF) gene (Val66Met, rs6265, G>A) polymorphism and breast cancer (BC) among females of Southern Pakistan. METHODS: This case-control study consisted of 300 females (BC cases [n = 100] and controls [n = 200]) with age range of 18 to 45 years. All participants were recruited during January to December 2014 and were screened for depression using Zung depression scale. Isolation of genomic DNA (gDNA) followed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis was done. All statistical analysis was carried out on IBM-SPSS version 22 at P-value <.05. Hardy-Weinberg equilibrium (HWE), Pearson chi-square, and odds ratios (ORs) with 95% confidence interval (95% CI) were calculated. RESULTS: Genotype distribution of BDNF gene polymorphism lies in the goodness-of-fit model among controls. The statistical analyses reveal a significant association between genotype frequencies (χ2 = 12.709, P-value = .002) of BDNF and BC among cases and controls. The AA genotype (OR = 5.2, 95%CI = 0.632-42.804) increases the risk of having BC. CONCLUSIONS: Our results suggest that BDNF gene polymorphism may have an association with BC risk among Pakistani females. However, the present finding needs to be replicated with greater sample size with BC risk.

Comparison of Polymerase Chain Reaction and Immunohistochemistry Assays for Analysing Human Papillomavirus Infection in Oral Squamous Cell Carcinoma.

INTRODUCTION: Polymerase Chain Reaction (PCR) and Immunohistochemistry (IHC) are two well-known techniques used for the diagnoses of genetic diseases, tumours and different pathogens. PCR basically amplify regions of DNA within a single molecule which may have etiologic significance, it is a method for in vitro amplification of specific DNA or RNA sequences, whereas IHC is used to verify tissue constituents (the antigens) with the utilization of specific antibodies that can be visualized through staining. AIM: To compare and analyse PCR and IHC for their sensitivity to detect Human Papillomavirus (HPV) in Oral Squamous Cell Carcinoma (OSCC). MATERIALS AND METHODS: This study was based on samples retrospectively collected from 47 patients with primary OSCC who were diagnosed and treated at The Aga Khan University Hospital, Karachi, Pakistan, during the period of January 2010 to December 2013. Inclusion criteria were complete clinicopathologic data, adequate clinical follow up and availability of sufficient paraffin- embedded tumour material. HPV general and type specific 16 and 18 were investigated by means of PCR. HPV immunoreactivity was further investigated by means of IHC. RESULTS: Among the 47 evaluated patients, 32 (68.1%) were male and 15 (31.9%) were female, PCR detected the presence of HPV in 32 (68.1%) patients while IHC showed no positive test results. p53 was positive in 32 (68.1%) patients and negative in 15 (31.9%). HPV type 16 being most prevalent showing positivity in 27 (57.4%) patients whereas, type 18 was positive in only 1 (2.1%) patient. CONCLUSION: We concluded that PCR is more sensitive and reliable when diagnosing and detecting HPV for OSCC rather than IHC as results from IHC were all negative and insignificant, hence PCR should be the first initial diagnostic test for detecting HPV due to its better sensitivity and successful detection of HPV.

Eating disorders in medical students of Karachi, Pakistan-a cross-sectional study.

BACKGROUND: To assess the incidence of high-risk population of medical students with eating disorders in Karachi by using validated self-administered questionnaires. The earlier these disorders are diagnosed and assessed, the better the chances are for enhanced treatment and fuller recovery. Therefore, we intended to undertake a study to find out the frequency of such disorders among medical students of Karachi and design strategies to overcome them. FINDINGS: A descriptive cross sectional study was conducted in 435 medical students of Karachi. Data was collected using 2 self administered questionnaires, the SCOFF Eating Disorders Questionnaire and the Eating Attitudes Test (EAT-26). Subjects' body mass indexes (BMI) were also calculated. The data was sorted and analyzed in SPSS version 16. According to EAT-26, 22.75% individuals were found to be at high-risk of eating disorders, with 87.9% females and 12.1% males. However, according to SCOFF questionnaire, 17% individuals were found to be at high-risk, with 78.4% females and 21.6% males. According to BMI calculation, 9% were severely underweight, 41.4% underweight, 41.1% normal, 7.6% overweight and 0.9% belonged to obese class 1. CONCLUSIONS: A significant fraction of medical students in Karachi are at high risk of development of eating disorders, females being more prone than males. Strategies should be designed to prevent occurrence of such disorders among medical students that would undoubtedly hamper the availability of dependable medical services in future.
