Background Qatar is experiencing rapid population expansion with increasing demands on healthcare services for both acute and chronic conditions. Sourcing accurate information about health conditions is crucial, yet the methods used for sourcing health information in Qatar are currently unknown. Gaining a better understanding of the sources the Qatari population use to recognize and manage health and/or disease will help to develop strategies to educate individuals about existing and emerging health problems. Objective To investigate the methods used by the Qatari population to source health information. We hypothesized that the Internet would be a key service used to access health information by the Qatari population. Methods A researcher-led questionnaire was used to collect information from Qatari adults, aged 18–85 years. Participants were approached in shopping centers and public places in Doha, the capital city of Qatar. The questionnaire was used to ascertain information concerning demographics, health status, and utilization of health care services during the past year as well as sources of health information used. Results Data from a total of 394 eligible participants were included. The Internet was widely used for seeking health information among the Qatari population (71.1%). A greater proportion of Qatari females (78.7%) reported searching for health-related information using the Internet compared to Qatari males (60.8%). Other commonly used sources were family and friends (37.8%) and Primary Health Care Centers (31.2%). Google was the most commonly used search engine (94.8%). Gender, age and education levels were all significant predictors of Internet use for heath information (P<0.001 for all predictors). Females were 2.9 times more likely than males (P<0.001) and people educated to university or college level were 3.03 times more likely (P<0.001) to use the Internet for heath information. Conclusions The Internet is a widely used source to obtain health-related information by the Qatari population. Internet search engines can be utilized to guide users to websites, developed and monitored by healthcare providers, to help convey reliable and accurate health information to Qatar’s growing population.

Objective The prevalence of polycystic ovary syndrome (PCOS) in the Qatari population is unknown and hence the estimated impact on the local population cannot be determined. The purpose of this study was to estimate the prevalence and metabolic features of PCOS among Qatari women. Design Cross sectional analysis. Patients 3,017 Qatari subjects volunteered to be phenotyped and genotyped for the Qatar Biobank from which all women between the ages of 18–40 years were identified (750). Measurements 720 women had testosterone and sex hormone binding globulin (SHBG) measurements. PCOS was diagnosed according the National Institute of Health (NIH) Guidelines of a raised androgen level (free androgen index >4.5 or a raised total testosterone) and menstrual irregularity after the exclusion of other conditions. Results All results are reported as mean value of PCOS versus control. 87 of 720 women fulfilled the NIH guidelines (12.1%) for PCOS specifically using a free androgen index greater than 4.5 or a total testosterone greater than 2.7nmol/l and menstrual irregularity. Subjects were heavier with a more metabolic profile of a greater systolic and diastolic blood pressure, higher levels of C reactive protein, insulin (p<0.01) and HbA1c (P<0.02), and decreased HDL levels (p<0.01). Pulse wave velocity as a marker of arterial stiffness was also increased (p<0.05) Conclusions By NIH guidelines the prevalence of PCOS in this Qatari cohort was 12.1% that would likely reflect 20% by Rotterdam criteria, with a markedly more metabolic phenotype than Qatari controls.

Recruitment into clinical research studies is a major challenge. This study was carried out to explore the perceptions and attitudes towards clinical research participation among the general public in Qatar. A population based questionnaire study was carried out at public events held in Qatar. Residents of Qatar, 18 years or above in age were surveyed, anonymously, following verbal consent. Descriptive and multivariate analyses were conducted. We administered 2517 questionnaires to examine clinical research participation, of which 2379 complete forms were analyzed. Those who had previously been approached to participate in research completed a more detailed assessment. Data showed that only 5.7% participants (n = 134) had previously been approached to participate in a clinical research study. Of these 63.4% (n = 85) had agreed to participate while 36.6% (n = 49) had declined. The main reasons for declining participation included: time constraint (47.8%, n = 11), ‘fear’ (13.0%, n = 3), lack of awareness about clinical research (8.7%, n = 2) and lack of interest (8.7%, n = 2). ‘To help others’ (31.8%, n = 27) and ‘thought it might improve my access to health care’ (24.7%, n = 21) were the prime motivators for participation. There was a general agreement among participants that their previous research experience was associated with positive outcomes for self and others, that the research conduct was ethical, and that opportunities for participation will be welcomed in future. More than ten years of stay within Qatar was a statistically significant determinant of willingness to participate, adjusted odds ratio 5.82 (95% CI 1.93–17.55), p = 0.002. Clinical research participation in Qatar needs improvement. Time constraints, lack of trust in and poor awareness about clinical research are main barriers to participation. Altruism, and improved health access are reported as prime motivators. Deeper insight in to the factors affecting clinical research participation is needed to devise evidence based policies for improvement in recruitment strategies.

There is evidence from animal and in-vitro studies that activation of the endocannabinoid system (EC) through cannabinoid receptor 1 (CB-1) is associated with liver injury, inflammation and hepatocellular carcinoma.1 Data suggests endogenous cannabinoids (EC) are related to fatty liver metabolism with a role in non-alcoholic fatty liver disease (NAFLD) through modulating lipid metabolism that may be ameliorated by CB1 receptor antagonism with rimonabant.2 This is of particular importance as NAFLD is the most common cause of chronic liver disease with liver dysfunction leading liver cirrhosis. The diagnosis of NAFLD can only be confirmed by a liver biopsy, as liver enzymes such as alanine aminotransferase (ALT) used, as a serum marker may not be elevated.
