BackgroundTobacco use is the most important preventable cause of premature death and major risk factor for non-communicable diseases. Due to strict tobacco legislation in the western hemisphere, many African nations like Nigeria have shifted from being a tobacco-producing nation to a tobacco-consuming one. The purpose of this study was to systematically review existing literature on tobacco use among Nigerian adolescents and young people and identify the prevalence, distribution and factors influencing of tobacco smoking. These data are necessary to formulate and adapt control measures aimed at tobacco cessation among young people, and preventing long-term smoking behaviors.MethodsThree databases (African Journals Online, PsychInfo, PubMed) were searched for peer-reviewed publications, published between January 2000 and March 2017. Additional searches were completed on Google Scholar, and other documents and reports of the Nigerian government and the Global Youth Tobacco Survey were consulted. Using the PRISMA guidelines to evaluate studies, we included studies that reported prevalence of tobacco use in adolescents or youths, aged 10 to 24, and excluded evaluations of tobacco-related medical conditions.ResultsA total of 30 studies with a total population of 26,709 were reviewed. Prevalence rates of tobacco smoking ranged from 0.2% to 32.5%. Among the gender-specific studies, the prevalence of smoking among females ranged between 2.2% to 10% while that of males ranged from 1% to 32.5%. Gender distribution among these studies was mixed (80.0%), males only (13.3%) and females only (6.7%). Smoking prevalence was higher among males than females. The most common risk factors for tobacco use included peer influence, family conditions, psychosocial factors and male gender. Additional risk factors included concomitant substance abuse, media advertisements and increasing age.ConclusionsTobacco smoking poses a huge burden to Nigerian youths and various determinants were highlighted in this review. It is imperative that all stakeholders engage in concerted efforts to target both in-school and out-of-school youths in tobacco control strategies.

The prevalence of household food insecurity in this study was high. Living conditions were significantly associated with food insecurity. Socio-economic conditions need to be improved, to optimize the health and food security status of people living with HIV in Sagamu.

Conclusion WhatsApp can be an effective tool for health professional education, using a pre-defined curriculum coupled with organizational structure. This study reported both subjective and objective measures of effectiveness and demonstrated that the use of multiple e-learning resources can lead to improved learning outcomes.

To support the global restart of elective surgery, data from an international prospective cohort study of 8492 patients (69 countries) was analysed using artificial intelligence (machine learning techniques) to develop a predictive score for mortality in surgical patients with SARS-CoV-2. We found that patient rather than operation factors were the best predictors and used these to create the COVIDsurg Mortality Score (https://covidsurgrisk.app). Our data demonstrates that it is safe to restart a wide range of surgical services for selected patients.

Introduction the mental and physical stimulating effects of caffeine have led to an increase in consumption of caffeinated beverages. Adolescents are at an increased risk of excessive caffeine consumption and its associated adverse health consequences. This study therefore assessed the pattern of caffeinated drink consumption among in-school adolescents in Sagamu, Ogun State, Nigeria. Methods a descriptive, cross-sectional study was carried out among 350 adolescents in Sagamu Township, selected via multistage sampling. Data were collected using a semi-structured self-administered questionnaire and analyzed with SPSS version 20.0. Relevant descriptive and inferential statistics were calculated with level of significance (p) set at <0.05. Results respondents' mean age was 14.49 ± 1.37 years; 60.2% of respondents were male. Over 90% of respondents consumed caffeinated beverages; 19.2% consumed greater than 3 cans in a day; 67.8% always felt a strong urge to consume caffeinated drinks. Reasons for consumption include: to aid personal study (64.4%), thirst (47.1%), performance enhancement (34.1%), alertness (30.6%) and hunger (17.7%). Reported side effects include: nervousness (40.4%); mood swings (16.5%); palpitations (30.1%); insomnia (51.6%). Conclusion consumption of caffeinated beverages was high among adolescents in Sagamu. Adequate caffeine control measures, with behavior change communication, will help to address this public health challenge among adolescents.

HIV prevalence and transmission is still of public health concern in low-resource climes like Nigeria. Transactional sex is a well-known risk factor for HIV transmission. This study therefore assessed the prevalence of transactional sex and associated factors among women attending the antiretroviral clinic in Sagamu, Nigeria. A cross-sectional study was carried out among 204 women attending antiretroviral treatment center in Sagamu, Ogun State, Nigeria, selected via total population recruitment. Data were collected using a validated, semistructured questionnaire. Respondents’ written informed consent was obtained. The mean age of respondents was 38.3 ± 9.0 years. Two thirds (66%) were in monogamous marriages. About two thirds (64.2%) had at least secondary education. Almost 50% spent more than half of their income on food. About 90% had commenced antiretroviral therapy. The prevalence of transactional sex was 7.4%. Household size ( p = .031), marital status ( p = .015), reduction of food ration ( p = .010), skipping of medication ( p = .001), and starving for a whole day ( p = .044) were associated with transactional sex. Food assistance programs, socioeconomic empowerment schemes, and targeted counseling should be given to people living with HIV to halt HIV transmission.

A 30-year-old male presented with a history of recurrent episodes of acute cholecystitis; first acute attack associated with fever and nausea was 18 months prior to this presentation, for which he was managed conservatively for acute cholecystitis with antibiotics and analgesia following an ultrasound that showed features of acute cholecystitis with no obvious gallstones. The patient had further episodes of acute cholecystitis with no signs of obstructive jaundice and subsequent ultrasound showed multiple small gallstones. Due to the severity of his symptoms, he was scheduled for a planned cholecystectomy. During surgery (right subcostal incision)- findings were that of a contracted gall bladder with dense adhesions, after careful dissection a fistulous tract between the appendix and gallbladder was identified along with a cholecystoduodenal fistula. An en-bloc cholecystectomy plus appendicectomy was performed with the duodenotomy repaired. On the first day post op there was approximately 300 ml of bilious effluent in drain, a white cell count-8.1 x 109 and hemoglobin -12.1 g/dL, Serum bilirubin-1.4mg/dL, ALP-104mg/dL. The second and third post-operative days were uneventful with minimal bile mixed serous fluid in drain respectively with no other complains, following which the drains were removed and patient discharged home. Biliary-enteric fistulae have been found in 0.9% of patients undergoing biliary tract surgery. The most common site of communication of the fistula is a cholecystoduodenal (70%), followed by cholecystocolic (10–20%), and the least common is the cholecystogastric fistula accounting for the remainder of cases. No case of cholecystoappendicular fistula has been reported so far.
