COVID-19 spread rapidly in Brazil despite the country’s well established health and social protection systems. Understanding the relationships between health-system preparedness, responses to COVID-19, and the pattern of spread of the epidemic is particularly important in a country marked by wide inequalities in socioeconomic characteristics (eg, housing and employment status) and other health risks (age structure and burden of chronic disease).

To familiarize the reader with the most common cutaneous adverse events with immune checkpoint inhibitors (CPIs) and their grading and treatment.

Surgical healthcare has been prioritised in the Southern African Development Community (SADC), a regional intergovernmental entity promoting equitable and sustainable economic growth and socioeconomic development. However, challenges remain in translating political prioritisation into effective and equitable surgical healthcare. The AfroSurg Collaborative (AfroSurg) includes clinicians, public health professionals and social scientists from six SADC countries; it was created to identify context-specific, critical areas where research is needed to inform evidence-grounded policy and implementation. In January 2020, 38 AfroSurg members participated in a theory of change (ToC) workshop to agree on a vision: ‘An African-led, regional network to enable evidence-based, context-specific, safe surgical care, which is accessible, timely, and affordable for all, capturing the spirit of Ubuntu’ and to identify necessary policy and service-delivery knowledge needs to achieve this vision. A unified ToC map was created, and a Delphi survey was conducted to rank the top five priority knowledge needs. In total, 45 knowledge needs were identified; the top five priority areas included (1) mapping of available surgical services, resources and providers; (2) quantifying the burden of surgical disease; (3) identifying the appropriate number of trainees; (4) identifying the type of information that should be collected to inform service planning; and (5) identifying effective strategies that encourage geographical retention of practitioners. Of the top five knowledge needs, four were policy-related, suggesting a dearth of much-needed information to develop regional, evidenced-based surgical policies. The findings from this workshop provide a roadmap to drive locally led research and create a collaborative network for implementing research and interventions. This process could inform discussions in other low-resource settings and enable more evidenced-based surgical policy and service delivery across the SADC countries and beyond.

Gastrointestinal side effects are common during oral immunotherapy (OIT) and eosinophilic esophagitis (EoE) is a potential complication. We aimed to characterize eosinophilic gastrointestinal responses to peanut OIT, in which peanut protein is given orally, with incremental increases in dose over time.

Evidence on local disease burden and the completeness of case detection represent important information for TB control programs. We present a new method for estimating subnational TB incidence and the fraction of individuals with incident TB who are diagnosed and treated in Brazil.
