Facteurs pronostiques des pneumopathies acquises sous ventilation mécanique en réanimation polyvalente du CHU d'Angre (RCI) / Prognostic factors for pneumopathy acquired under mechanical ventilation in multi-purpose resuscitation at the Angre CHU (RCI)

Objectifs : Identifier les facteurs de mauvais pronostic des pneumopathies acquises sous ventilation mécanique(PAVM) afin d'améliorer leur prise en charge.Patients et methode : Etude prospective, descriptive et analytique portant sur les patients admis en réanimation du CHU d'Angré du 1er novembre 2019 au 31 juillet 2021 et ayant présenté une PAVM.Resultats : Nous avons colligé 43 patients sur 625 admissions soit 6,88%. L'âge moyen était de 49,06 ans. Le sex ratio était de 0,38. Le principal motif d'admission était le coma avec 88,37%. L'HTA et le diabète étaient les principaux antécédents .Les PAVM précoces représentaient 53,49%. Le Klebsiella pneumoniae était le principal germe. Les patients intubés à l'admission représentaient 79,07%. La durée moyenne de ventilation était de 26,95 jours et la durée moyenne d'hospitalisation était de 30,8140 jours. Une antibiothérapie probabiliste a été réalisée chez 75,76% des patients. La mortalité était de 76,74%. Les facteurs de mortalité étaient une durée de ventilation mécanique supérieure à 15 jours et l'âge supérieur à 50 ans.Conclusion :La mortalité secondaire au PAVM demeure élevée. L'identification des deux facteurs pronostiques devrait améliorer la prise en charge ultérieure de tous nouveaux cas

Objectives: To identify the factors of poor prognosis of ventilator-associated lung disease (VAP) in order to improve their management. Patients and method: Prospective, descriptive and analytical study of patients admitted to intensive care at the Angré University Hospital from November 1, 2019 to July 31, 2021 and having presented VAP.Results: We collected 43 patients out of 625 admissions, i.e. 6.88%. The average age was 49.06 years. The sex ratio was 0.38. The main reason for admission was coma with 88.37%. Hypertension and diabetes were the main antecedents. Early VAP accounted for 53.49%. Klebsiella pneumoniae was the main germ. Patients intubated on admission accounted for 79.07%. The average duration of ventilation was 26.95 days and the average duration of hospitalization was 30.8140 days. Probabilistic antibiotic therapy was performed in 75.76% of patients. Mortality was 76.74%. The mortality factors were duration of mechanical ventilation greater than 15 days and age greater than 50 years.Conclusion:Secondary mortality from VAP remains high. The identification of the two prognostic factors should improve the subsequent management of all new cases.

Clinicopathological Studies on Rats Exposed to Municipal Landfill Gaseous and Particulate Emissions

The study assessed the Clinicopathological changes of Wistar rats exposed to municipal landfill gaseous particulate emissions. Four groups of Wistar rats were exposed to the different sites of landfill emission with use of filters for filtering landfill gaseous emission while the control group was not exposed. Performance of the animals was evaluated weekly, blood and lung, liver, kidney and heart tissues were taken for haematological and histopatholgical examinations. At the end of six weeks exposure, the peak weight was recorded as 108.96±0.45 of Group B as compared to 126.352±0.88 of the Control Group, as well as the decrease in the body weight of Group A-D compared to the Control Group. There was leucocytosis, lymphocytosis and neutrophilia in the rats that were exposed to landfill emission. There were pulmonary, hepatic, and renal lesions while the heart was spared. Changes were observed on the use of filters for filtering landfill gaseous emission. The 3M 6001 CN Gas Mask Carnister Cartridge which filters 50% of landfill emission together with black polythene nylon restricting external air into the filtered cage was not sufficient to reduce the effect of landfill gaseous emission at the end of the exposure period. The screening with PM2.5 material which filters 100% of PM2.5 emission was only able to screen PM2.5 emission but could not screen other landfill gaseous emission. This indicates that landfill gaseous emission is capable of inducing respiratory problems and tissue damage on dumpsite workers if there is sufficient and continuous exposure to landfill gaseous emissions. To prevent the hazard that may arose from dumpsite activities; gas nose mask respirator is recommended for an individual who works as scavengers and landfill workers before entering the dumpsite environment..

COVID-19, disability and the context of healthcare triage in South Africa: Notes in a time of pandemic

During disasters, when resources and care are scarce, healthcare workers are required to make decisions and prioritise which patients receive life-saving resources over others. To assist healthcare workers in standardising resources and care, triage policies have been developed. However, the current COVID-19 triage policies and practices in South Africa may exclude or disadvantage many disabled people, especially people with physical and intellectual impairments, from gaining intensive care unit (ICU) access and receiving ventilators if becoming ill. The exclusion of disabled people goes against the principles established in South Africa's Constitution, in which all people are regarded as equal, have the right to life and inherent dignity, the right to access healthcare, as well as the protection of dignity. In addition, the triage policy contravenes the United Nations Convention on the Rights of Persons with Disabilities, which the South African government has signed and ratified. This article raises debates about whose lives matter and whose lives are 'worth' saving over others, and although the focus is on South Africa, the issues may be relevant to other countries where life-saving resources are being rationed
