Since 2018, WHO has endorsed the use of whole-genome sequencing (WGS) of Mycobacterium tuberculosis complex isolates to detect drug-resistant tuberculosis (DR-TB). This endorsement was based on the assumption that a faster and more detailed description of the resistance profile would improve treatment prescription for DR-TB by healthcare providers, and hence the treatment outcomes of patients. Nonetheless, this assumption has not been tested in routine clinical practice and different scenarios. In Brazil, WGS is not routinely used for the diagnosis of DR-TB, having been carried out in only a few centres for research purposes. With this trial, we will evaluate whether a WGS-based drug-resistance report improves treatment adequacy in patients with pulmonary DR-TB, compared with the current standard-of-care diagnostic methods used in the state of São Paulo, Brazil.
We will conduct a non-randomised controlled clinical trial with two arms to compare the intervention group (ie, individuals receiving a WGS-based report) with a historical control group (i.e., individuals who received resistance diagnostics based on the standard of care of conventional genotyping and phenotyping techniques). The primary outcome will be the proportion of patients whose treatment scheme was adequate based on complete resistance profile determined by WGS and/or phenotypic drug-susceptibility testing (pDST). Other secondary outcomes will also be considered. The target sample size is 88 eligible patients per group. The intervention group will be prospectively recruited over 18 months and the control group will be composed of patients diagnosed with pulmonary DR-TB up to 2 years before the start of the trial. To ensure comparability, isolates from the control group will undergo WGS retrospectively, and pDST will be performed retrospectively in both groups. This clinical trial will take place in six medical centres for the treatment of DR-TB in the state of São Paulo. This study is intended to support the implementation of the WGS in the routine diagnosis of DR-TB in the state of São Paulo.
Ethical approval was obtained from the Human Research Committee of the Institute of Biomedical Sciences, University of São Paulo, Brazil (CAAE: 79497924.1.1001.5467). Study results will be published in peer-reviewed journals and disseminated to policymakers and stakeholders.

The main objective of the Health Survey of São Paulo or Inquérito de Saúde de São Paulo (ISA) in Portuguese, is to generate health indicators to support research and policy planning. The ISA-Physical Activity and Environment Longitudinal Study has the primary objective of examining built and social environmental determinants of leisure-time physical activity and active transportation.
The baseline (2014–2015) study included 4042 participants aged 12 years and older, men and women, living across the five regions of São Paulo city. Data were collected through household interviews. The second wave (2020–2021) used telephone interviews and included 1434 participants aged 18 or older, 58.6% female and representing 35% of the baseline sample. The third wave (2023–2024) included 1583 participants through household or telephone interviews, 58.6% of female and represented 39% of the original cohort.
The study has collected extensive individual-level data, including physical activity behaviours, health status and related behaviours, self-report of diseases and sociodemographic characteristics; built environment features such as public open spaces, transport infrastructure, schools and healthcare facilities, walkability index, sidewalks, traffic control and social environment features, such as crime occurrence and socioeconomic index. Analyses have identified changes in the built environment and their associations with physical activity and obesity. Infrastructure improvements, such as the increase of bike paths and outdoor gyms, have been more frequent in wealthier areas, reinforcing spatial inequalities. Increased availability of public open spaces has been associated with increased leisure-time walking. Obesity has shown a growing trend, particularly among specific sociodemographic groups, while physical activity has demonstrated protective effects against obesity. Cycling for transportation has remained stable over time, with disparities by gender and physical activity status.
The plan is to conduct the fourth wave in 2026 and 2027 and the fifth wave in 2029 and 2030.

BackgroundGlobally, more than 720,000 people die by suicide each year, leaving grieving individuals in their wake. Research indicates that individuals who lose a loved one to suicide face heightened risks for negative health outcomes. Recent studies show that taking part in meaningful activities can help protect health emphasizing the importance of exploring engagement in meaningful activities of everyday living among those bereaved. Currently, there has not been a review of the bereavement literature exploring the nature of, and extent to which, meaningful activities of everyday living are discussed.
ObjectiveTo explore the nature of, and extent to which the peer-reviewed, suicide bereavement literature addresses engagement in meaningful activities of everyday living.
MethodsA scoping review following the Joanna Briggs Institute’s framework was completed to summarize and map the literature. Four electronic databases were searched for two concepts: suicide and bereavement. Studies were screened using specific inclusion and exclusion criteria. Two independent reviewers completed title and abstract, and full text screening for each article. All conflicts were resolved through discussion or by a third reviewer. Data were charted, summarized and results were reported using the PRISMA Extension for Scoping Reviews.
Results12372 studies were identified; 112 studies met inclusion criteria. Studies used qualitative (n = 90), quantitative (n = 10) and mixed (n = 12) methods. Findings indicate that the suicide bereavement literature discusses engagement in meaningful activities of everyday living using three main components: activities of everyday living, the engagement status of activities, and the meaning associated with activities.
DiscussionWhile references to meaningful activities of everyday living appear in the bereavement literature, they typically are discussed within the background rather than central research aims. There is a need to bring this discussion to the forefront and view engagement in meaningful activities of everyday living as an important aspect of suicide bereavement.
Dementia is a chronic and progressive neurological condition characterised by cognitive and functional impairment. It is often associated with multimorbidity and imposes a significant economic burden on healthcare systems and families, especially in low-income and middle-income countries. In Peru, where dementia cases are increasing rapidly, timely detection and referral for diagnosis is crucial. This protocol is part of the IMPACT Salud project in Peru. Here, we focus on a specific component aimed at validating an mHealth tool for the detection of cognitive and functional impairment and assessing its cost-effectiveness. We will also assess changes in cognitive and functional impairment as well as health economic outcomes over 1 year.
This observational study will be conducted in four geographically diverse regions of Peru. Community health workers are expected to contact approximately 32 000 participants (≥60 years) to apply an mHealth-enabled tool that includes cognitive and functional instruments: Ascertain Dementia 8, Peruvian version of Rowland Universal Dementia Assessment Scale and Pfeffer Functional Activities Questionnaire. From this large sample, we aim to find 3600 participants and their study partners to enrol and interview at baseline regarding sociodemographic characteristics, lifestyles, comorbidities and health economic data including resource use, costs and health-related quality of life (HR-QoL). Psychologists, blind to previous results, will assess dementia stage of the participants using an abbreviated Clinical Dementia Rating (CDR) scale. At 6-month follow-up, participants will complete a brief health economics questionnaire on resource use, costs and HR-QoL. To validate the accuracy of the detection tool, a subsample of 600 participants who completed the baseline will undergo a gold-standard clinical neuropsychological assessment. This subsample will participate in a 12-month follow-up, including health economics, cognitive and functional impairment tests and the CDR scale. Results will be analysed and presented by cognitive status, site, sex and multimorbidity profile. Finally, data from all stages and external sources will inform a decision model to implement a cost-effectiveness analysis of the detection tool at the national level.
The study received ethics approval in Peru (Universidad Peruana Cayetano Heredia: CONSTANCIA-CIEI-378-33-23) and in the UK (Imperial College London: ICREC/SETREC reference number 6647445). Informed consent will be obtained from participants and their study partners, considering the participant’s capacity to consent. For illiterate participants, consent will be obtained through a witnessed procedure involving study partners, with a fingerprint obtained instead of a signature. The results will be disseminated through conferences, published articles, public presentations (particularly to those involved in dementia care) and presentations or meetings with local health authorities.

Developing a strong skeleton during growth is critical for minimizing fractures later in life. Prior work showed that bone mass varied with external bone size, a measure of the outer bone width. We tested how this association affected the identification of children with low bone mass. Radiographs of the nondominant hand of 45 White females and 54 White males, all ~ 8 years old, were assessed and second metacarpal length (Le) and the midshaft outer and inner widths were measured at the 40, 50, and 60% midshaft sites. The average total area (Tt.Ar), a measure of the area enclosed by the periosteal surface, and cortical area (Ct.Ar), a measure of bone mass, were calculated assuming a circular cross-section. Individuals were sorted into tertiles using robustness (Tt.Ar/Le). Z-scores were calculated for Ct.Ar first using the cohort mean and standard deviation and second using each robustness tertile mean and standard deviation. Females and males with Z-scores in the lower 33% range were identified for the group-average and tertile-specific average comparisons. Agreement between the two reference group approaches was determined using Cohen’s kappa statistic for each sex. The percentage of individuals identified with low Ct.Ar depended on whether Z-scores were compared to the group average or tertile-specific averages. When compared to the group average, 67% of females and 56% of males identified with lower Ct.Ar were from the narrowest tertile, whereas 0% of females and 22% of males were from the widest tertile. For females and males, Cohen’s kappa coefficient showed almost perfect agreement for the intermediate tertile (kappa coefficient > 0.84), but agreement was only poor to moderate (kappa coefficientA assistência psiquiátrica brasileira começou nas Santas Casas de Misericórdia até o surgimento dos hospitais psiquiátricos. Os objetivos deste estudo foram identificar vestígios do cuidado de enfermagem em psiquiatria nas primeiras instituições criadas no estado do Piauí, região Nordeste do Brasil e analisar suas relações com a institucionalização deste grupo na primeira metade do
século XX. Trata-se de um estudo qualitativo, histórico social, com dados publicados na mídia jornalística, coletados em arquivos públicos brasileiros. A análise, sob o referencial teórico foucaultiano, seguiu a metodologia de triangulação das fontes e interpretação de dados. Resultados: duas instituições iniciaram a assistência psiquiátrica no estado: o Asylo de Alienados, instituição pública criada em 1907, e o Sanatório Meduna, instituição privada inaugurada em 1954. Apesar do intervalo de 47 anos entre tais instituições, ambas instituíram o modelo manicomial, cuja prática assistencial incluía longos períodos de internação e tratamento disciplinar. Tal modelo abriu o mercado de trabalho para a enfermagem em psiquiatria, que se constituiu inicialmente de pessoas sem preparo formal, devido a inexistência de cursos de enfermagem no estado. Conclusão: o cuidado de enfermagem em psiquiatria foi institucionalizado no
Piauí/Brasil de acordo com a psiquiatria tradicional e a ausência de um saber próprio da enfermagem a colocou em condições de submissão ao poder médico, com poucos avanços na primeira metade do século XX.
La enfermería es una disciplina relativamente joven y con un prometedor futuro. Un aspecto para considerar puede ser el papel que en tanto disciplina científica pueda desarrollar como puente en la disputa entre la cultura científica y la humanística. Para ello se analiza en qué consiste el problema de la tercera cultura, se examina lo que pudo ser un ejemplo de búsqueda de esa tercera cultura en la educación y, finalmente, se hace referencia a la enfermería como ese punto arquemídeo que bien pudiera hacer de pasarela entre esas dos orillas antitéticas.
Por otra parte, estas reflexiones pondrán al descubierto la necesidad de una reflexión profunda y pausada sobre los fundamentos sustanciales (epistemológicos) de la disciplina. Está en juego el establecimiento de la disciplina enfermera como autónoma y, al mismo tiempo, su legitimación científica, alejándola del permanente espejismo de entenderla como secundaria o vicaria respecto de otras.
