Introduction: COVID-19 is a pandemic disease caused by the coronavirus SARS-COV2 appeared in China in 2019. The aim of the study was to evaluate the practice of barrier measures against COVID-19 and to identify associated factors among diabetics followed at Departmental University Hospital Center Ouémé-Plateau, Benin, in 2021. Methods: This was a cross-sectional study conducted from June to August 2021, including diabetics aged 18 and over, hospitalized or received for medical visits in the department of medicine at the target hospital. Data were collected during an interview with each participant thanks to a questionnaire. “Good practice” was defined as regular practice of at least two of three barrier measures: hand washing, physical distancing and mask-wearing. Results: A total of 110 diabetics were included with a female predominance (55.5%) and a mean age of 57 ± 11.3 years. Among them, 89.1% washed their hands, 41.8% respected physical distancing and 12.7% wore a mask. The proportion of good practice was 47.3%. Only 5 practiced the three barrier measures. Only age group was associated with good practice. Conclusion: The study showed a low proportion of good practice of barrier measures against COVID-19 among diabetic people surveyed. It is important to continue the action for COVID-19 prevention among diabetic people in the targeted hospital and in other hospitals in Benin.

Background: Despite the advances in anesthetics and non-pharmacological techniques, the prevalence of postoperative nausea and vomiting in all patients remains high. It is one of the most common distressing symptoms that cause dissatisfaction among patients after anesthesia and surgery. A sub-hypnotic dose of propofol has been shown to reduce morphine-induced postoperative nausea, vomiting, and pruritus. This review article will provide sufficient knowledge on the role of propofol in minimizing opioid-induced postoperative nausea, vomiting, and pruritus by providing detailed information on propofol antiemetic and antipruritic effects, as well as discussions based on empirically available data. Method: We conducted a narrative review of the literature published between 1990 and 2023 from a range of databases;PubMed, BioMed Central, Biosis Previews, Nature, International Pharmaceutical Abstracts, Springer-Link, and Elsevier. Discussion and Conclusion: The literatures reviewed in this study have demonstrated that propofol may have diverse therapeutic effects including antiemetic and antipruritic. The antiemetic effect of propofol may be an effective therapeutic approach for the prevention of postoperative nausea and vomiting. The literature also demonstrated that the use of propofol for sedation during surgery may as well ameliorates opioids induced postoperative pruritus, which may be beneficial to surgical patients. Also, it was demonstrated that prophylactic use of propofol may be an effective way of preventing nausea and vomiting and pruritus during opioid use.

For much of the world＇s population, food is the major source of exposure to *** to this non-essential metalloid at relatively low levels may be linked to a wide range of adverse health effects. Thus, evaluating foods as sources of exposure to arsenic is important in assessing risk and developing strategies that protect public health. Although most emphasis has been placed on inorganic arsenic as human carcinogen and toxicant, an array of arsenic-containing species are found in plants and animals used as foods. Here,we 2evaluate the contribution of complex organic arsenicals（arsenosugars, arsenolipids,and trimethylarsonium compounds） that are found in foods and consider their origins,metabolism, and potential toxicity. Commonalities in the metabolism of arsenosugars and arsenolipids lead to the production of di-methylated arsenicals which are known to exert many toxic effects. Evaluating foods as sources of exposure to these complex organic arsenicals and understanding the formation of reactive metabolites may be critical in assessing their contribution to aggregate exposure to arsenic.
