Stroke but no hospital admission: Lost opportunity for whom?

To counter the spread of COVID-19, the French government imposed several stringent social and political measures across its entire population. We hereto assess the impact of these political decisions on healthcare access in 2020, focusing on patients who suffered from an ischemic stroke. We divide our analysis into four distinct periods: the pre-COVID-19 pandemic period, the lockdown period, the "in-between" or transitional period, and the shutdown period.

Examining the structure of plant-lemur interactions in the face of imperfect knowledge.

Biotic interactions, such as plant-animal seed dispersal mutualisms, are essential for ecosystem function. Such interactions are threatened by the possible extinction of the animal partners. Using a data set that includes plant-lemur interactions across Madagascar, we studied the current state of knowledge of these interactions and their structure to determine which plant species are most at risk of losing dispersal services due to the loss of lemurs.

Assessment of domestic pig-bushpig (Potamochoerus larvatus) interactions through local knowledge in rural areas of Madagascar.

In many parts of the world, domestic and wild animal populations interact at the interface between natural and agricultural ecosystems. Introduced with the first inhabitants arriving from eastern Africa, the bushpig (Potamochoerus larvatus) is the largest living terrestrial mammal in Madagascar. Bushpigs are regularly reported close to human settlements where they damage crops and gardens.

Performance of Mucorales spp. qPCR in bronchoalveolar lavage fluid for the diagnosis of pulmonary mucormycosis.

To estimate the diagnostic performance of Mucorales polymerase chain reaction (PCR) in Bronchoalveolar lavage fluid (BALF) in routine practice. This was a single-center retrospective study including all consecutive patients >18 years who underwent Mucorales PCR assay in BALF between January 2021 and May 2022. Index testing was prospectively performed using the MycoGENIE Aspergillus spp.

Psychoactive substance intoxication leading to general hospital admission in young and middle-aged people during and after the first lockdown.

Introduction: Incidence of hospitalisations related to psychoactive substance (H-PS) intoxication has been strongly decreased during the coronavirus disease 2019 (COVID-19) pandemic especially in young adult and French region of Nouvelle-Aquitaine was mostly concerned. This study aimed to describe (i) the incidence of H-PS in Bordeaux teaching hospital during and after the first 2020 lockdown in adults aged 18-29 years or 30+ then (ii) their characteristics specifically associated with the pandemic period by comparing 2020 with 2017-2019 baseline period.

Material And Methods: This historical cohort study was conducted in adults admitted to the Bordeaux teaching hospital with main or associated diagnosis codes of intoxication with benzodiazepine, methadone, buprenorphine, codeine, morphine, heroin, cocaine, ecstasy and alcohol.

Increase in hospitalisation-associated methadone intoxication in France following first COVID-19 lockdown.

Objectives: At the beginning of the COVID-19 pandemic, the French Addictovigilance Network drew attention to the need to facilitate access to methadone while ensuring its safe use, in order to avoid the occurrence of overdoses and deaths. The objectives of the study were to assess the impact of the lockdowns on the incidence of methadone-use-related hospitalisations (MUHs) and describe the characteristics of patients and hospitalisations.

Study Design: An interrupted time series using the unobserved components model was performed to predict the monthly incidence of MUHs in 2020 on the basis of previous years' data and compared with MUHs observed.

Obstacles to routine immunization in Madagascar: Structural, relational and cultural constraints.

This article proposes an overview of anthropological studies concerning childhood immunization in Madagascar, where vaccine coverage still remains low. The COVID-19 epidemic has heightened the reticence of populations to be vaccinated in the public health centres of this country. It appears necessary to study the factors which may impact immunization practices and its representations.

General hospital admissions in young and middle-aged people who use psychoactive substances: Impact of Covid-19 lockdowns.

Backgrounds: The Covid-19 pandemic offered a unique opportunity to investigate trends in hospitalizations related to psychoactive substance intoxication, since the usual health burden of social use at parties and gatherings was likely to be decreased during lockdowns and curfew periods. Since young adults are the main users of psychoactive substances for experimental and recreational purposes, this study identified and compared hospitalization trends in young adults and adults over 30 years old.

Methods: This national cohort study was conducted using the French hospital discharge database.

Factors influencing maternal healthcare seeking in a highland region of Madagascar: a mixed methods analysis.

Background: In Madagascar, maternal mortality remains stable and high (426 deaths per 100,000 live births). This situation is mainly due to a delay or lack of use of maternal healthcare services. Problems related to maternal healthcare services are well documented in Madagascar, but little information related to maternal healthcare seeking is known.

Dementia in subjects aged 75 years or over within the PAQUID cohort: prevalence and burden by severity.

Background/aims: To analyze the prevalence of dementia by severity and to describe the sociodemographic characteristics of people with dementia in the community, as well as the consequences of this disease in terms of disability and institutionalization.

Methods: This study was based on the PAQUID community-based cohort study of 1,461 subjects aged 75 years or over. Severity of dementia was assessed using the Mini-Mental State Examination (MMSE).

Time-updated CD4+ T lymphocyte count and HIV RNA as major markers of disease progression in naive HIV-1-infected patients treated with a highly active antiretroviral therapy: the Aquitaine cohort, 1996-2001.

In naive HIV-1 infected patients who start a highly active antiretroviral therapy (HAART), the relationship between time-updated CD4+ cell count, HIV RNA, and clinical progression (new AIDS-defining event or death) is incompletely understood. A 2-step statistical approach was adopted: first, modeling the evolution of the 2 markers taking into account left-censoring of HIV RNA and, second, studying their respective effect on clinical progression. The study sample consisted in 551 previously untreated patients of the Aquitaine Cohort who started their first HAART regimen between 1996 and 2000.

[Prevalence of dementia and Alzheimer's disease among subjects aged 75 years or over: updated results of the PAQUID cohort].

The progression of the prevalence of dementia in developed countries will increase the difficulties of medical and psycho-social management of demented patients and their family. The aim of this study was to estimate the prevalence of dementia among subjects aged 75 years and over. These subjects have been followed-up ten years after the baseline examination of the PAQUID study, a prospective population-based cohort study on normal and pathological aging after 65 years.

Malaria prevention during pregnancy in unstable transmission areas: the highlands of Madagascar.

Malaria transmission in Madagascar is highly variable from one region to the next, and the consequences of the disease on pregnant women and their foetuses are not fully documented. In midwestern Madagascar, the high-transmission lowlands in the west of the country meet the central plateaux, where malaria is unstable because of the high altitude and annual indoor spraying of DDT since 1993. We studied five of the region's main maternity clinics.
