Tuberculosis (TB) is one of the deadliest infectious diseases in the world with more than a million people dying of TB each year. Accurate and timely TB diagnosis has the potential to alleviate the ...global TB burden; therefore, one of the pillars of the End TB Strategy developed by the World Health Organization (WHO) is the early diagnosis of TB, including universal drug-susceptibility testing (DST). The WHO emphasises the importance of DST before treatment initiation, using molecular WHO-recommended rapid diagnostic tests (mWRDs). Currently available mWRDs are nucleic acid amplification tests, line probe assays, whole genome sequencing, and targeted next-generation sequencing. However, implementing the sequencing mWRDs in routine laboratories in low-income countries is constrained by the existing infrastructure, high cost, the specialised skills needed, data storage, and the current delay in results compared with other routine methods. These limitations are pronounced in resource-limited settings, which often have a high TB burden and need for innovative TB diagnostic technologies. In this article we propose several possible solutions, like adapting infrastructure capacity to needs, advocating for lowering costs, building bioinformatics and laboratory capacity, and increasing the use of open-access resources for software and publications.
Tuberculosis (TB) is one of the leading causes of mortality in people living with HIV (PLHIV) and contributes to up to a third of deaths in this population. The World Health Organization guidelines ...aim to target early detection and treatment of TB among PLHIV, particularly in high-prevalence and low-resource settings. Prevention plays a key role in the fight against TB among PLHIV. This review explores TB screening tools available for PLHIV, including symptom-based screening, chest radiography, tuberculin skin tests, interferon gamma release assays, and serum biomarkers. We then review TB Preventive Treatment (TPT), shown to reduce the progression to active TB and mortality among PLHIV, and available TPT regimens. Last, we highlight policy-practice gaps and barriers to implementation as well as ongoing research needs to lower the burden of TB and HIV coinfection through preventive activities, innovative diagnostic tests, and cost-effectiveness studies.
Un renversement topique et plusieurs retournements et contrepoints mythologiques définissent la structure du Phèdre . Régenté par Socrate, ce rythme syncopé de secousse et d’apaisement, propre à une ...initiation, traverse tout le dialogue. En cartographiant les redressements mythologiques et rhétoriques, les rétractations signifiées par le mouvement palinodique, les retournements de fond (vie/mort, virginité/fécondité) et les traversées de limites indiquées par des détails topographiques et des rituels, on arrive à saisir le tableau dynamique de l’âme que Platon ne définit pas mais met en œuvre en y intégrant son lecteur.
Influenza-associated deaths is an important risk for the elderly in nursing homes (NHs) worldwide. Vaccination coverage among residents is high but poorly effective due to immunosenescence. Hence, ...vaccination of personnel is an efficient way to protect residents. Our objective was to quantify the seasonal influenza vaccination (IV) coverage among NH for elderly workers and identify its determinants in France.
We conducted a cross-sectional study in March 2016 in a randomized sample of NHs of the Ille-et-Vilaine department of Brittany, in western France. A standardized questionnaire was administered to a randomized sample of NH workers for face-to-face interviews. General data about the establishment was also collected.
Among the 33 NHs surveyed, IV coverage for the 2015-2016 season among permanent workers was estimated at 20% (95% Confidence Interval (CI) 15.3%-26.4%) ranging from 0% to 69% depending on the establishments surveyed. Moreover, IV was associated with having previously experienced a "severe" influenza episode in the past (Prevalence Ratio 1.48, 95% CI 1.01-2.17), and varied by professional categories (p < 0.004) with better coverage among administrative staff. Better knowledge about influenza prevention tools was also correlated (p < 0.001) with a higher IV coverage. Individual perceptions of vaccination benefits had a significant influence on the IV coverage (p < 0.001). Although IV coverage did not reach a high rate, our study showed that personnel considered themselves sufficiently informed about IV.
IV coverage remains low in the NH worker population in Ille-et-Vilaine and also possibly in France. Strong variations of IV coverage among NHs suggest that management and working environment play an important role. To overcome vaccine "hesitancy", specific communication tools may be required to be adapted to the various NH professionals to improve influenza prevention.

There are major gaps in the management of pediatric tuberculosis (TB) contact investigation for rapid identification of active tuberculosis and initiation of preventive therapy. This study aims to ...evaluate the impact of a community-based intervention as compared to facility-based model for the management of children in contact with bacteriologically confirmed pulmonary TB adults in low-resource high-burden settings.
This multicenter parallel open-label cluster randomized controlled trial is composed of three phases: I, baseline phase in which retrospective data are collected, quality of data recording in facility registers is checked, and expected acceptability and feasibility of the intervention is assessed; II, intervention phase with enrolment of index cases and contact cases in either facility- or community-based models; and III, explanatory phase including endpoint data analysis, cost-effectiveness analysis, and post-intervention acceptability assessment by healthcare providers and beneficiaries. The study uses both quantitative and qualitative analysis methods. The community-based intervention includes identification and screening of all household contacts, referral of contacts with TB-suggestive symptoms to the facility for investigation, and household initiation of preventive therapy with follow-up of eligible child contacts by community healthcare workers, i.e., all young (< 5 years) child contacts or older (5-14 years) child contacts living with HIV, and with no evidence of TB disease. Twenty clusters representing TB diagnostic and treatment facilities with their catchment areas are randomized in a 1:1 ratio to either the community-based intervention arm or the facility-based standard of care arm in Cameroon and Uganda. Randomization was stratified by country and constrained on the number of index cases per cluster. The primary endpoint is the proportion of eligible child contacts who initiate and complete the preventive therapy. The sample size is of 1500 child contacts to identify a 10% difference between the arms with the assumption that 60% of children will complete the preventive therapy in the standard of care arm.
This study will provide evidence of the impact of a community-based intervention on household child contact screening and management of TB preventive therapy in order to improve care and prevention of childhood TB in low-resource high-burden settings.

The 2021 Global Tuberculosis (TB) report shows slow progress towards closing the pediatric TB detection gap and improving the TB preventive treatment (TPT) coverage among child and adolescent ...contacts. This review presents the current knowledge around contact case management (CCM) in low-resource settings, with a focus on child contacts, which represents a key priority population for CCM and TPT. Compelling evidence demonstrates that CCM interventions are a key gateway for both TB case finding and identification of those in need of TPT, and their yield and effectiveness should provide a strong rationale for prioritization by national TB programs. A growing body of evidence is now showing that innovative models of care focused on community-based and patient-centered approaches to household contact investigation can help narrow down the CCM implementation gaps that we are currently facing. The availability of shorter and child-friendly TPT regimens for child contacts provide an additional important opportunity to improve TPT acceptability and adherence. Prioritization of TB CCM implementation and adequate resource mobilization by ministries of health, donors and implementing agencies is needed to timely close the gap.
Background
Chronic hepatitis C virus (HCV) infection negatively impacts health-related quality of life (HRQL). We aimed to assess patient-reported outcomes (PROs) to evaluate the impact of treating ...chronic HCV with directly acting antivirals (DAAs) on HRQL.
Methods
PROs were assessed prospectively using the PROQOL-HCV questionnaire before (week 0), at the end (week 12), and after DAA treatment at week 24. HRQL was measured in six different dimensions: physical health, emotional health, future uncertainty, intimate relationships, social health, and cognitive functions.
Results
A total of 500 HCV patients receiving DAAs were enrolled; of them, 399 were included in the analysis (median age 57 years, 59% females). HRQL increased significantly between baseline, end of treatment, and week 24 for all dimensions (
P
< 0.001), more often for physical health in females compared to males (OR = 1.69, 95% CI = 1.1–2.5), for future uncertainty among people with diabetes (1.75, 95% CI = 1.05–2.9), and for cognitive functions among obese patients (OR = 1.98; 95% CI = 1.1–3.3). Improvement in HRQL was less common for intimate relations among females (OR = 0.47; 95% CI = 0.3–0.7) and in patients with cirrhosis (OR = 0.35, 95% CI = 0.1–0.7). Improvement in HRQL was consistently higher in < 60 years compared to ≥ 60 years patients, with a significant difference in social health (
P
< 0.001) and future uncertainty (
P
< 0.049) HRQL domains.
Conclusion
HRQL improved with DAA therapy, a relation consistent across all HRQL dimensions up to 12 weeks after the end of treatment.
Background Tuberculosis preventive treatment (TPT) in child household contacts is recommended by World Health Organization (WHO) but limited data has been reported on the costs experienced by ...households with children receiving TPT. Methods We evaluated the economic impact on households with children receiving TPT within a service-delivery model cluster-randomised controlled trial in Cameroon and Uganda. The intervention included community health worker-led home-based child-contact screening, TPT initiation and monitoring, and referral of children with presumptive tuberculosis or side effects, and was compared with each country’s facility-based standard of care (control). We used a retrospective cross-sectional survey adapted from the WHO Global task force on tuberculosis patient cost surveys. All costs were collected between February 2021 and March 2021 and are presented in 2021 US$. Results The median household costs estimated using the human capital approach were higher in the control arm ($62.96 interquartile range, IQR; $19.78-239.74 in Cameroon and $35.95 IQR; $29.03-91.26 in Uganda) compared to the intervention arm ($2.73 IQR; $2.73-14.18 in Cameroon and $4.55 IQR; $3.03-6.06 in Uganda). Using a threshold of 20% of annual household income, 15% (95%CI; 5-31%) of households in Cameroon and 14% (95%CI; 4-26%) in Uganda experienced catastrophic costs in the control compared to 3% (95%CI; 1- 8%) in Cameroon and 3% (95%CI; 1-8%) in Uganda in the intervention. Using the output-based approach to estimate income losses increased costs by 14-32% in the control and 13-19% in the intervention across the two countries. The proportion of participants experiencing any dissaving was higher in the control, 53% (95%CI; 36-71%) in Cameroon and 50% (95%CI; 31-69%) in Uganda, compared to 18% (95%CI; 10-29%) in Cameroon and 17% (95%CI; 8-28%) in Uganda in the intervention. Conclusions Households with child contacts initiated on TPT under a facility-based model incur significant costs. Community-based interventions help to reduce these costs but do not eliminate catastrophic expenditures. Registration https://clinicaltrials.gov/ct2/show/NCT03832023.
Si le traité Du sublime n’est pas un manuel de tropes, de quoi parle-t-il lorsqu’il cite différentes manières de produire une réalité de parole à même d’arracher le lecteur à sa réalité propre ? La ...réponse la plus brève serait : de la condition même du langage, mais autrement qu’Aristote à travers la théorie de la catharsis . La perte des repères sensibles produite par une émotion suscitée sciemment s’associe avec le mouvement contraire qui vise à stabiliser l’effet en indiquant la source et le but du pathos. Un changement soudain de registre a lieu à travers cet échange. L’émoi dévoile l’âme, tandis que la parole qui produit cet effet participe en même temps de la stabilité implicite à la nature supérieure de l’âme, dont elle montre le caractère universel et transcendant. Merveilleuse ou sublime est alors la parole qui à la fois réveille et éclaire. Plus qu’une question d’usage (et implicitement de style), il s’agit d’une conception selon laquelle le langage est intimement et inextricablement lié à l’âme, étant la plus secrète et la plus fidèle de ses manifestations. C’est donc une théorie de l’âme qui se dégage d’une analyse des liens entre les deux productions conjointes dont il est question dans le traité dit Du sublime – l’effet d’émoi (de stupeur) et celui de clarté (d’évidence hors de doute) –, les deux agissant sur le lecteur pour lui permettre d’atteindre le merveilleux ou le divin qui se tient en lui dès lors qu’il peut le découvrir, mais auquel il n’a accès qu’en suivant le sentier extérieur dessiné par les paroles d’autrui : un maître du logos que l’on entend ou lit. Ce processus est celui que décrit Platon dans le Phèdre . Le traité Du sublime s’appuie sur ce dernier de manière tantôt explicite et tantôt subtile, en recourant au pouvoir du langage de fabriquer et de montrer des images. Le but de notre étude est d’indiquer certaines traces du Phèdre dans le texte de la moitié du i er s. afin d’orienter la lecture vers la nature plutôt philosophique que stylistique du traité sur le sublime. En retour, ce dernier pourrait constituer un repère dans la compréhension du rôle assigné au Phèdre dans un moment charnière de l’héritage de l’Académie, celui qui inaugure l’époque dite du moyen platonisme.
There is little evidence on the impact of the COVID-19 pandemic on Public Health Residents' (PHR) mental health (MH). This study aims at assessing prevalence and risk factors for depression, anxiety ...and stress in European PHR during the COVID-19 pandemic.
Between March and April 2021, an online survey was administered to PHR from France, Italy, Portugal and Spain. The survey assessed COVID-19 related changes in working conditions, training opportunities and evaluated MH outcomes using the Depression Anxiety Stress Scales-21. Multivariable logistic regressions were applied to identify risk factors.
Among the 443 respondents, many showed symptoms of depression (60.5%), anxiety (43.1%) and stress (61.2%). The main outcome predictors were: female gender for depression (adjOR = 1.59, 95%CI 1.05-2.42), anxiety (adjOR = 2.03, 95%CI 1.33-3.08), and stress (adjOR = 2.35, 95%CI 1.53-3.61); loss of research opportunities for anxiety (adjOR = 1.94, 95%CI 1.28-2.93) and stress (adjOR = 1.98, 95%CI 1.26-3.11); and COVID-19 impact on training (adjOR = 1.78, 95%CI 1.12-2.80) for depression.
The pandemic had a significant impact on PHR in terms of depression, anxiety and stress, especially for women and who lost work-related opportunities. Training programs should offer PHR appropriate MH support and training opportunities.
