Prevalence, awareness, treatment, and control of hypertension in Bissau, Western Africa

Hypertension is the leading preventable risk factor for cardiovascular diseases. In Guinea–Bissau there are no previous population-based hypertension surveys. Therefore, the authors aimed to estimate the prevalence, awareness, treatment, and control of high blood pressure among adults living in Bissau. A sample (n = 973) of dwellers in Bissau, aged 18–69 years, was assembled through stratified and cluster sampling. Patients underwent face-to-face interviews and blood pressure measurements following the World Health Organization Stepwise Approach to Chronic Disease Risk Factor Surveillance. The prevalence of hypertension was 26.9%, and 51.4% of hypertensive individuals were aware of their condition, of whom 51.8% reported having received pharmacological treatment in the previous 2 weeks. Among the latter, 49.9% had blood pressure values below 140/90 mm Hg. These findings show that hypertension has become a major public health problem in Guinea-Bissau, emphasizing the urgent need to develop and implement national strategies for the prevention and management of hypertension. © 2022 The Authors.

Prevalence of Underweight, Overweight and Obesity among Adults in Urban Bissau, Western Africa

Overweight and obesity affect a large proportion of the population and are important causes of death in both developed and low- and middle-income countries. In Guinea-Bissau, there are no previous population-based studies assessing this phenomenon. Therefore, we aimed to quantify the prevalence of underweight, overweight, and obesity among adults in Bissau. A stratified and cluster sample of 935 adults was assembled in 2021 and was evaluated using standardized questionnaires and anthropometric measurements, following the World Health Organization Stepwise Approach to Chronic Disease Risk Factor Surveillance. Underweight, obesity, and overweight were defined by body mass index based on the World Health Organization definitions. The prevalence of overweight and obesity was 48.7% among women and 25.0% among men. The proportion of women with abdominal obesity was 14 times higher than it was in men (35.3% vs. 2.5%). The prevalence of overweight and obesity increased with age and income. Underweight was more prevalent in the age group of 18 to 24 years (18.4% in women and 28.9% in men) and was less frequent among individuals with higher socioeconomic status. In conclusion, the prevalence of overweight and obesity is similar to the trends that are observed in many other urbanized populations in Africa and is already a major public health issue in urban Guinea-Bissau.This research received no external funding

A aposição nos gêneros editorial e artigo de opinião:um enfoque funcionalista da liguagem

Objetivou-se, nesta pesquisa, investigar as correlações existentes entre as construções apositivas e os propósitos comunicativos dos gêneros editorial e artigo de opinião. O presente estudo desenvolveu-se no intuito de dar comprovação à hipótese de que os aspectos formais, semânticos e discursivos das construções apositivas estão estritamente relacionados com os propósitos sociocomunicativos dos gêneros selecionados. Quanto ao corpus da pesquisa, foram analisadas 85 (oitenta e cinco) ocorrências de aposição nos gêneros editorial e artigo de opinião, veiculados na revista Veja e nos jornais Folha de S. Paulo e A Gazeta. Como aporte teórico para as discussões aqui propostas, elegemos os preceitos do funcionalismo linguístico, por ser esta uma corrente linguística que se preocupa em estudar a relação entre a estrutura gramatical das línguas e os diferentes contextos comunicativos em que elas são usadas. A partir das análises feitas quanto à frequência de determinadas formas sintáticas, relações semânticas e funções textual-discursivas, concluímos a pesquisa inferindo que as construções apositivas contribuem de maneira significativa para o cumprimento dos propósitos comunicativos dos gêneros editorial e artigo de opinião

Changes in prevalence and the cascade of care for type 2 diabetes over ten years (2005-2015): results of two nationally representative surveys in Mozambique

Background: Sub-Saharan Africa is predicted to have the steepest increase in the prevalence of diabetes in the next 25 years. The latest Mozambican population-based STEPS survey (STEPS 2005) estimated a 2.9% prevalence of diabetes in the adult population aged 25-64 years. We aimed to assess the change in prevalence, awareness, and management of diabetes in the national STEPS survey from 2014/2015 compared to 2005. Methods: We conducted an observational, quantitative, cross-sectional study following the WHO STEPS surveillance methodology in urban and rural settings, targeting the adult population of Mozambique in 2015. We collected sociodemographic data, anthropometric, and 12 hour fasting glucose blood samples in a sample of 1321 adults. The analysis consisted of descriptive measures of the prevalence of impaired fasting glucose (IFG), diabetes and related risk factors by age group, sex, and urban/rural residence and compared the findings to those of the 2005 survey results. Results: The prevalence of IFG and diabetes was 4.8% (95CI: 3.6-6.3) and 7.4% (95CI: 5.5-10.0), respectively. These prevalence of IFG and diabetes did not differ significantly between women and men. The prevalence of diabetes in participants classified with overweight/obesity [10.6% (95CI: 7.5-14.6)] and with central obesity (waist hip ratio) [11.0% (95CI: 7.4-16.1)] was almost double the prevalence of their leaner counterparts, [6.3% (95CI, 4.0-9.9)] and [5.2% (95CI: 3.2-8.6)], respectively. Diabetes prevalence increased with age. There were 50% more people with diabetes in urban areas than in rural. Only 10% of people with diabetes were aware of their disease, and only 44% of those taking oral glucose-lowering drugs. The prevalence of IFG over time [2.0% (95CI: 1.1-3.5) vs 4.8% (95CI: 3.6-6.3)] and diabetes [2.9% (95CI: 2.0-4.2) vs 7.4% (95CI: 5.5-10.0)] were more than twofold higher in 2014/2015 than in 2005. However, awareness of disease and being on medication decreased by 3% and by 50%, respectively. Though this was not statistically significant. Conclusions: While the prevalence of diabetes in Mozambique has increased from 2005 to 2015, awareness and medication use have declined considerably. There is an urgent need to improve the capacity of primary health care and communities to detect, manage and prevent the occurrence of NCDs and their risk factors. © 2022, The Author(s).The study was supported by the Mozambican Ministry of Health and by the WHO.

Standardization of techniques used in facial nerve section and facial movement evaluation in rats

AIM: standardization of the technique to section the extratemporal facial nerve in rats and creation of a scale to evaluate facial movements in these animals before and after surgery. STUDY DESIGN: Experimental. METHOD: twenty Wistar rats were anesthetized with ketamine xylazine and submitted to sectioning of the facial nerve near its emergence through the mastoid foramen. Eye closure and blinking reflex, vibrissae movement and positioning were observed in all animals and a scale to evaluate these parameters was then created. RESULTS: The facial nerve trunk was found between the tendinous margin of the clavotrapezius muscle and the auricular cartilage. The trunk was proximally sectioned as it exits the mastoid foramen and the stumps were sutured with a 9-0-nylon thread. An evaluation and graduation scale of facial movements, independent for eye and vibrissae, was elaborated, together with a sum of the parameters, as a means to evaluate facial palsy. Absence of eye blinking and closure scored 1; the presence of orbicular muscle contraction, without blinking reflex, scored 2; 50% of eye closure through blinking reflex, scored 3, 75% of closure scored 4. The presence of complete eye closure and blinking reflex scored 5. The absence of movement and posterior position of the vibrissae scored 1; slight shivering and posterior position scored 2; greater shivering and posterior position, scored 3 and normal movement with posterior position, scored 4; symmetrical movement of he vibrissae, with anterior position, scored 5. CONCLUSION: The rat anatomy allows easy access to the extratemporal facial nerve, allowing its sectioning and standardized suture. It was also possible to establish an evaluation and graduation scale of the rat facial movements with facial palsy based on the clinical observation of these animals.OBJETIVOS: Padronização da técnica de secção do nervo facial extratemporal em ratos e elaboração de uma escala de avaliação da mímica facial desses animais antes e após essa secção. TIPO DE ESTUDO: Experimental. MÉTODO: Vinte ratos Wistar foram anestesiados com xilasina e ketamina e submetidos à secção do nervo facial próximo à sua emergência pelo forame mastóideo na pele. Todos os animais foram avaliados. Foram observados: fechamento ocular, reflexo de piscamento, movimentação e posicionamento das vibrissas, e foi elaborada uma escala de avaliação e graduação destes parâmetros. RESULTADOS: O tronco do nervo facial foi encontrado entre a margem tendinosa do músculo clavotrapézio e a cartilagem auricular. O tronco foi seccionado proximal à sua saída pelo forame mastóideo e os cotos foram suturados com nylon 9-0. Foi elaborada uma escala de avaliação e graduação da mímica facial independente para olho e vibrissa e a somatória dos parâmetros, como forma de avaliar a face paralisada. A ausência de piscamento e de fechamento ocular recebeu valor 1; a presença de contração do músculo orbicular, sem reflexo de piscamento, valor 2; fechamento ocular de 50% através de reflexo de piscamento, valor 3, o fechamento de 75%, valor 4. A presença de reflexo de piscamento com fechamento ocular completo recebeu valor 5. A ausência de movimento e posição posterior das vibrissas recebeu pontuação 1; tremor leve e posição posterior, pontuação 2; tremor maior e posição posterior, pontuação 3 e movimento normal com posição posterior, pontuação 4. A movimentação simétrica das vibrissas, com posição anterior recebeu pontuação 5. CONCLUSÃO: O rato apresenta anatomia que permite fácil acesso ao nervo facial extratemporal, possibilitando secção e sutura desse nervo de forma padronizada. Também foi possível estabelecer uma escala de avaliação e graduação da mímica facial dos ratos com paralisia facial a partir da observação clínica desses animais.UNIFESPUNIFESP-EPMUNIFESP, EPMSciEL

Prevalence of Cardiovascular Risk Factors among Young Adults (18-25 Years) in Mozambique

The life course development of cardiovascular diseases (CVDs) and the undergoing epidemiological transition in Mozambique highlight the importance of monitoring the cardiovascular risk profile in young adults. Therefore, this study aims to estimate the prevalence of CVD risk factors in a population aged 1825 years living in Mozambique. A total of 776 young adults from a nationally representative sample were evaluated in 2014/2015 following the World Health Organizations STEPwise approach to chronic disease risk factor surveillance. Current smoking was the most prevalent among rural men (10.8%, 95%CI: 6.317.8), and drinking was most prevalent among urban men (38.6%, 95%CI: 29.348.8). The proportion of young adults not engaging in at least 75 min of vigorous physical activity per week ranged between 14.5% in rural men and 61.6% in urban women. The prevalence of being overweight/obese and hypertension were highest among urban women (21.6%, 95%CI: 14.730.6) and urban men (25.2%, 95%CI: 15.937.6), respectively. Education >8 years (vs. none) was independently associated with lower odds of being a current smoker, and increased monthly household income was associated with increased odds of low levels of physical activity. This study shows that important CVD risk factors are already common in the young adult population of Mozambique.</jats:p
