ABSTRACT

BACKGROUND: Knowledge about factors influencing access and adherence to TB care, and on the impact of the COVID-19 pandemic on TB care in resource-restricted settings is scarce. We conducted this study in Atsimo-Andrefana, a rural region in southern Madagascar where TB prevalence, poverty and food insecurity rates are high. We aimed to determine facilitators and barriers to access to and provision of TB care in rural Madagascar during the COVID-19 pandemic. METHODS: We conducted qualitative focus group discussions (FGDs) and in-depth interviews (IDIs) with patients with TB, community health workers, facility-based health workers, public health officials and non-governmental organisation staff. We analysed interviews using thematic analysis. RESULTS: We conducted 11 FGDs and 23 IDIs. We identified three main barriers to access and adherence to TB care: 1) stigma, 2) indirect treatment costs, and 3) food insecurity. The facilitator perceived as most influential was high health worker motivation. The effects of the COVID-19 pandemic on TB care varied between stake-holders; some health workers described delays in TB diagnosis and increased workload. CONCLUSIONS: To improve access and adherence to TB care, both indirect treatment costs and stigma need to be reduced; undernourished patients with TB should receive food support.


CONTEXTE: Les connaissances sur les facteurs influençant l'accès et l'adhésion aux soins antituberculeux, ainsi que sur l'impact de la pandémie de COVID-19 sur les soins antituberculeux dans les milieux à ressources limitées sont rares. Nous avons mené cette étude à Atsimo-Andrefana, une région rurale du sud de Madagascar où la prévalence de la TB et les taux de pauvreté et d'insécurité alimentaire sont élevés. Nous avons cherché à déterminer les facilitateurs et les obstacles à l'accès et à la fourniture de soins antituberculeux dans les zones rurales de Madagascar pendant la pandémie de COVID-19. MÉTHODES: Nous avons mené des discussions qualitatives en groupe (FGD) et des entretiens approfondis (IDI) avec des patients atteints de tuberculose, des agents de santé communautaires, des agents de santé en établissement, des responsables de la santé publique et des membres d'organisations non gouvernementales. Nous avons analysé les entretiens en utilisant l'analyse thématique. RÉSULTATS: Nous avons mené 11 FGD et 23 IDI. Nous avons identifié trois principaux obstacles à l'accès et à l'observance des soins antituberculeux : 1) la stigmatisation, 2) les coûts indirects du traitement et 3) l'insécurité alimentaire. Le facilitateur perçu comme le plus influent était la forte motivation des agents de santé. Les effets de la pandémie de COVID-19 sur les soins antituberculeux varient selon les parties prenantes ; certains agents de santé ont décrit des retards dans le diagnostic de la TB et une augmentation de la charge de travail. CONCLUSIONS: Pour améliorer l'accès et l'adhésion aux soins antituberculeux, il faut réduire à la fois les coûts indirects du traitement et la stigmatisation ; les patients tuberculeux sousalimentés devraient recevoir une aide alimentaire.

ABSTRACT

The removal of bone cement from the femoral canal in the case of hip prosthesis loosening takes a considerable amount of time and carries the additional risk of complications, thus risking bone damage and perhaps even endangering the successful reimplantation of a new prosthesis. We have demonstrated experimentally that the milling of bone and bone cement produces acoustic emission waves of different intensity. These waves can be measured by a commercial acoustic emission transducer. This method enables us to control a milling device during the removal of bone cement from deep in the femoral canal, avoiding the serious damage to the bone and thus enabling a new prosthesis to be reimplanted.

ABSTRACT

Mesna (sodium-2-mercaptoethansulfonate) is used in the prophylaxis of cyclophosphamide (CYC)-induced hemorrhagic cystitis. Four patients being treated with "low dose" CYC and prednisone for vasculitis developed severe side effects to Mesna. Fever, arthralgia, myalgia, tachycardia, electrocardiogram changes consistent with perimyocarditis, erythroderma, bullous skin and mucous membrane lesions, and abdominal complaints with profuse diarrhea were noted approximately 3 weeks after the initiation of therapy for CYC-induced leukopenia and a conservatively reduced prednisone dosage. Positive reexposure tests confirmed the association to Mesna use, and hypersensitivity skin tests demonstrated a delayed hypersensitivity reaction.
