Prevalence of overweight and obesity in adults from North Africa.

The share of North African immigrants in Europe is growing continuously. In this review, we aimed to systematically analyse and describe the literature on weight status and physical activity in North African adults, both in their home country and after immigration to Europe. Existing data on North African residents and on North African immigrants in Europe were analysed by a systematic search on PUBMED. There is a wide variation among countries in the prevalence of overweight/obesity, with immigrants showing higher values. The overall results revealed a higher prevalence of overweight and obesity in females than in males in North African residents. Females also show higher levels of obesity among immigrants. In particular, literature reports indicate that 1.3-47.8% of North African residents and 3.6-49.4% of North African immigrants in adult age are overweight or obese. Physical inactivity is higher than 20% in males and 40% in females in North African residents. The highest frequency of physically inactive or lightly active people among immigrants was observed in first-generation Sudanese and Moroccans in Amsterdam (males: 57.1%; females: 74.2%), with increasing rates in second-generation females. The results underline a higher health risk in North African immigrants than in residents. Specific public health strategies should be adopted in various populations of North African origin to control the obesity epidemic

Physicians are a key to encouraging cessation of smoking among people living with HIV/AIDS: a cross-sectional study in the Kathmandu Valley, Nepal

BackgroundHIV care providers may be optimally positioned to promote smoking behaviour change in their patients, among whom smoking is both highly prevalent and uniquely harmful. Yet research on this front is scant, particularly in the developing country context. Hence, this study describes smoking behaviour among people living with HIV/AIDS (PLWHA) in the Kathmandu Valley of Nepal, and assesses the association between experience of physician-delivered smoking status assessment and readiness to quit among HIV-positive smokers.MethodsWe conducted a cross-sectional survey of PLWHA residing in the Kathmandu Valley, Nepal. Data from 321 adult PLWHA were analyzed using multiple logistic regression for correlates of current smoking and, among current smokers, of motivational readiness to quit based on the transtheoretical model (TTM) of behaviour change.ResultsOverall, 47% of participants were current smokers, with significantly higher rates among men (72%), ever- injecting drug users (IDUs), recent (30-day) alcohol consumers, those without any formal education, and those with higher HIV symptom burdens. Of 151 current smokers, 34% were thinking seriously of quitting within the next 6 months (contemplation or preparation stage of behaviour change). Adjusting for potential confounders, experience of physician-delivered smoking status assessment during any visit to a hospital or clinic in the past 12 months was associated with greater readiness to quit smoking (AOR = 3.34; 95% CI = 1.05,10.61).ConclusionsRoughly one-third of HIV-positive smokers residing in the Kathmandu Valley, Nepal, are at the contemplation or preparation stage of smoking behaviour change, with rates significantly higher among those whose physicians have asked about their smoking status during any clinical interaction over the past year. Systematic screening for smoking by physicians during routine HIV care may help to reduce the heavy burden of smoking and smoking-related morbidity and mortality within HIV-positive populations in Nepal and similar settings

Biomarkers for Severity of Spinal Cord Injury in the Cerebrospinal Fluid of Rats

One of the major challenges in management of spinal cord injury (SCI) is that the assessment of injury severity is often imprecise. Identification of reliable, easily quantifiable biomarkers that delineate the severity of the initial injury and that have prognostic value for the degree of functional recovery would significantly aid the clinician in the choice of potential treatments. To find such biomarkers we performed quantitative liquid chromatography-mass spectrometry (LC-MS/MS) analyses of cerebrospinal fluid (CSF) collected from rats 24 h after either a moderate or severe SCI. We identified a panel of 42 putative biomarkers of SCI, 10 of which represent potential biomarkers of SCI severity. Three of the candidate biomarkers, Ywhaz, Itih4, and Gpx3 were also validated by Western blot in a biological replicate of the injury. The putative biomarkers identified in this study may potentially be a valuable tool in the assessment of the extent of spinal cord damage
