Knowledge of surgeons and practical stances of healthcare institutions in the Ile-de-France region toward sustainable development: A cross-sectional study.

PURPOSE OF THE STUDY: Climate change represents one of the gravest threats to health. Surgical activities mobilize a large number of resources which contribute to increased emission of CO2 and anesthetic gases in the environment. The objective of this study was to assess the level of knowledge of surgeons and the practical stances of healthcare establishments toward sustainable development. METHODS: This was a descriptive cross-sectional study, lasting 2 months. From 1 May 2021 to 30 June 2021, surgeons were asked via an online questionnaire to participate. RESULTS: A total of 131 out of the 457 contacted surgeons responded. A majority practiced in the private sector, 48.9% knew little about the rules of sustainable development in operating theaters, and 43.5% had an average level. The sustainable development charter was available in only 23% of establishments, while 19% had a sustainable development committee, and specific sustainable development actions were carried out in 27%. CONCLUSION: The level of knowledge of surgeons in Île-de-France on sustainable development was low. In general, surgical units were not complying with the rules of good practice on CO2 reduction. It is necessary to find strategies to reduce the impact of operating theaters on the environment.

[Laboratory testing including CD4 T-cell count and determination of viral load to evaluate the impact of first line antiretroviral treatment at 6 months in adults in Benin]. / Evaluation de l'efficacité du traitement anti-rétroviral par analyse des charges virales au Bénin.

The purpose of this study was to determine lymphocyte CD4 T-cell count and circulating HIV-1 RNA load in HIV-infected adults starting first line antiretroviral treatment according to the revised 2006 WHO recommendations in Cotonou, Benin. A total of 1209 adults treated mainly by lamivudine/stavudine/nevirapine, were prospectively included between November 2006 and June 2007. CD4 T-cell counts and HIV viral load (measured by branched DNA assay, Siemens, Tarytown, New York, USA) were evaluated at 6 months of treatment. Mean CD4 T-cell count showed a marked increase at six months of treatment (93/mm3 at baseline versus 387/mm3 at 6 months) with 65.2% of patients reaching a CD4 T-cell level higher than 200/mm3 and 34.8% showing CD4 T-cell counts lower than 200/mm3. At 6 months, HIV 1 viral load was undetectable (<2.70 log10 copies/ml) in only 54 patients (16.7%), detectable but lower than 3.0 log10 copies/ml in 522 (73%) patients, and high, i.e., still greater than 3.7 log10 copies/ml in 188 (27%) patients. After 18 months of follow up, 499 patients (41.3%) had undetectable circulating viral load. The three main findings of this study are that at 6 months of antiretroviral treatment i) one-third of patients remained at risk for opportunistic infection (CD4<200/mm3), ii) one-fourth met criteria for virological failure (> 5000 copies/ml), and iii) concordance between immunological and virological responses was frequent but discordance responses were observed in more than 10% of patients. Taken together, these findings underline the need to improve compliance and laboratory follow-up in patients undergoing antiretroviral therapy in Africa.
