Although the sex of an individual confers one of the greatest of the known risks for contracting leukaemia and lymphomas, very little attention is paid to these risks. It is the purpose of this paper to stimulate further research in this area. The sex rate ratios are presented for the commoner haematological malignancies. The male excess in the lymphoid cancers is most marked in the youngest age group in non-Hodgkin's lymphoma and Hodgkin's disease, while acute lymphoblastic leukaemia shows equal sex ratios in the childhood peak. Both chronic lymphocytic leukaemia and lymphocytic lymphoma display an unusual pattern, hitherto undescribed, with a large male excess specific to the 40s and 60s age groups. The myeloid sex ratios are all characterized by slight female excess in early adulthood followed by marked male excess. The reasons for these patterns are discussed.

This study aimed to evaluate the overall excess mortality and COVID-19 mortality in the regions of Brazil, in 2020, by sex and age group. An ecological study was carried out to calculate the overall excess mortality, by sex and age group, using the expected number of deaths in a non-pandemic context and the deaths observed in 2020. Data on deaths were extracted from the Brazilian Mortality Information System, in addition to population data from the Brazilian Institute of Geography and Statistics.

Objective: To estimate vaccination coverage and analyze factors associated with full vaccination among children up to 15 months old in the city of Natal-RN, Brazil.
Methods: Population-based survey with data recorded on children's vaccination cards and interviews conducted in 2020 and 2021. Analysis of factors associated with complete vaccination was performed by calculating prevalence ratios (PR) and 95% confidence intervals (95%CI) using Poisson regression.
Spine-Abductor Syndrome: Novel Associations Between Lumbar Spine Disease and Hip Gluteal Muscle Pathology.

Background: Risk factors for gluteal tears include age-related deterioration, female sex, and increased body mass index. As the literature that supports the sagittal relationship between the lumbar spine and the hip is increasing, there may be a parallel relationship between the perturbations in spinopelvic alignment caused by lumbar spine disease and gluteal muscle tears. Because no prior studies other than single-institution series have reported on this phenomenon, we investigated spine-abductor syndrome at the population level.

Background: The risk of onwards HIV transmission is strongly influenced by the interval between HIV infection and its diagnosis. The SELPHI trial examined whether this interval could be reduced by offering free HIV self-testing kits to men-who-have-sex with-men (MSM).
Setting: Internet-based RCT of MSM aged ≥16 years, resident in England/Wales, recruited via sexual and social networking sites.
