Tobacco use is a well-established risk factor for oesophageal squamous cell carcinoma (ESCC) but the extent of its contribution to the disease burden in the African oesophageal cancer corridor has not been comprehensively elucidated, including by type of tobacco use. We investigated the contribution of tobacco use (smoking and smokeless) to ESCC in Tanzania, Malawi and Kenya. Hospital-based ESCC case-control studies were conducted in the three countries.

Article Synopsis
  • Gastric cancer (GC) and oesophageal cancer (EC) have distinct epidemiological profiles, and their incidence rates and trends vary globally by subtype.
  • Data from population-based cancer registries showed that the ratio of GC to EC incidence differs significantly across regions, with GC being more prevalent in certain South American and Asian countries, while EC is predominant in sub-Saharan Africa.
  • Over the years 1998 to 2012, GC rates have generally decreased by 2%-3% annually, whereas EC trends vary by subtype, with increases in certain types like esophageal adenocarcinoma (EAC) and decreases in others like esophageal squamous cell carcinoma (ESCC).

Background: Ghana's national tuberculosis (TB) prevalence survey conducted in 2013 showed higher than expected TB prevalence indicating that many people with TB were not being identified and treated. Responding to this, we assessed barriers to TB case finding from the perspective, experiences and practices of healthcare workers (HCWs) in rural and urban health facilities in the Volta region, Ghana.

Methods: We conducted structured clinic observations and in-depth interviews with 12 HCWs (including five trained in TB case detection) in four rural health facilities and a municipal hospital.

Article Synopsis
  • A study was conducted in seven lower-income sub-Saharan African countries to assess if there is a link between the monovalent human rotavirus vaccine and intussusception in infants.
  • Researchers enrolled 717 infants with confirmed intussusception and evaluated the timing of their vaccination, specifically looking at periods shortly after receiving the vaccine.
  • The findings indicated that the risk of developing intussusception after vaccination did not exceed the normal background risk, suggesting that the vaccine is safe in these settings.

Background: Diarrhea causes about 10% of all deaths in children under five years globally, with rotavirus causing about 40% of all diarrhea deaths. Ghana introduced rotavirus vaccination as part of routine immunization in 2012 and it has been shown to be effective in reducing disease burden in children under five years. Ghana's transition from low to lower-middle income status in 2010 implies fewer resources from Gavi as well as other major global financing mechanisms.
