Delamanid-containing regimens and multidrug-resistant tuberculosis: A systematic review and meta-analysis

Introduction: Multidrug-resistant tuberculosis (MDR-TB) is a life-threatening condition needing long poly-chemotherapy regimens. As no systematic reviews/meta-analysis is available to comprehensively evaluate the role of delamanid (DLM), we evaluated its effectiveness and safety. Methods: We reviewed the relevant scientific literature published up to January 20, 2022. The pooled success treatment rate with 95% confidence intervals (CI) was assessed using a random-effect model. We assessed studies for quality and bias, and considered P0.05). The overall pooled treatment success rate in DLM and bedaquiline-containing regimens was 75.2% (95% CI 68.1-81.1) with no evidence of publication bias (Begg's test; P >0.05). In experimental studies the pooled treatment success rate of DLM-containing regimens was 72.5 (95% CI 44.2-89.8, P 0.05). Conclusions: In MDR-TB patients receiving DLM, culture conversion and treatment success rates were high despite extensive resistance with limited adverse events

Phenotypic and genotypic diversity of wine yeasts used for acidic musts

The aim of this study was to examine the physiological and genetic stability of the industrial wine yeasts Saccharomyces cerevisiae and Saccharomyces bayanus var. uvarum under acidic stress during fermentation. The yeasts were sub-cultured in aerobic or fermentative conditions in media with or without l-malic acid. Changes in the biochemical profiles, karyotypes, and mitochondrial DNA profiles were assessed after minimum 50 generations. All yeast segregates showed a tendency to increase the range of compounds used as sole carbon sources. The wild strains and their segregates were aneuploidal or diploidal. One of the four strains of S. cerevisiae did not reveal any changes in the electrophoretic profiles of chromosomal and mitochondrial DNA, irrespective of culture conditions. The extent of genomic changes in the other yeasts was strain-dependent. In the karyotypes of the segregates, the loss of up to 2 and the appearance up to 3 bands was noted. The changes in their mtDNA patterns were much broader, reaching 5 missing and 10 additional bands. The only exception was S. bayanus var. uvarum Y.00779, characterized by significantly greater genome plasticity only under fermentative stress. Changes in karyotypes and mtDNA profiles prove that fermentative stress is the main driving force of the adaptive evolution of the yeasts. l-malic acid does not influence the extent of genomic changes and the resistance of wine yeasts exhibiting increased demalication activity to acidic stress is rather related to their ability to decompose this acid. The phenotypic changes in segregates, which were found even in yeasts that did not reveal deviations in their DNA profiles, show that phenotypic characterization may be misleading in wine yeast identification. Because of yeast gross genomic diversity, karyotyping even though it does not seem to be a good discriminative tool, can be useful in determining the stability of wine yeasts. Restriction analysis of mitochondrial DNA appears to be a more sensitive method allowing for an early detection of genotypic changes in yeasts. Thus, if both of these methods are applied, it is possible to conduct the quick routine assessment of wine yeast stability in pure culture collections depositing industrial strains

Loving to Straighten Out Development: Sexuality and ‘Ethnodevelopment’ in the World Bank’s Ecuadorian Lending

Gender staff in the World Bank -- the world's largest and most influential development institution -- have a policy problem. Having prioritised efforts to get women into paid employment as the "cure-all" for gender inequality they must deal with the work that women already do -- the unpaid labour of caring, socialisation, and human needs fulfilment. This article explores the most prominent policy solution enacted by the Bank to this tension between paid and unpaid work: the restructuring of normative heterosexuality to encourage a two-partner model of love and labour wherein women work more and men care better. Through a case study of Bank gender lending in Ecuador I argue that staff are trying to (re)forge normative arrangements of intimacy, a policy preference that remains invisible unless sexuality is taken seriously as a category of analysis in development studies. Specifically, I focus on four themes that emerge from the attempt to restructure heteronormativity in the loan: (1) the definition of good gender analysis as requiring complementary sharing and dichotomous sex; (2) the Bank's attempt to inculcate limited rationality in women such that they operate as better workers while retaining altruistic attachments to loved ones; (3) the Bank's attempt to inculcate better loving in men, such that they pick up the slack of caring labour when their (partially) rational wives move into productive work, and; (4) the invocation of a racialised hierarchy resting on the extent to which communities approximate ideals of sharing monogamous partnership. Aside from providing clear evidence that the world's largest development institution is involved in micro-processes of sexuality adjustment alongside macro-processes of economic restructuring, I also critique the Bank's sexualised policy interventions and suggest that they warrant contestation
