BACKGROUND: It has been asserted that mammography screening preferentially benefits those with less aggressive cancers, with lesser or no impact on more rapidly progressing and therefore more life-threatening tumours. METHODS: We utilized data from the Swedish Two-County Trial, which randomized 77,080 women aged 40-74 to invitation to screening and 55,985 for usual care. We tabulated cancers by histological grade and then compared mortality from cancers specific to histological grade between the invited and control group using Poisson regression, with specific interest in the effect on mortality from grade 3 cancers...

We investigated the association between daily emergency ambulance calls (EAC) for elevated blood pressure that occurred during the time intervals of 8:00-13:59, 14:00-21:59, and 22:00-7:59, and exposure to CO, PM10, and ozone. We used Poisson regression to explore the association between the risk of EAC and short-term variation of pollutants, adjusting for seasonality and weather variables. Before noon, the risk was associated with an interquartile range (IQR) (7.9 μg/m(3)) increase in PM10 at lag 2-4 days below the median (RR = 1...

BACKGROUND: Non-administration of venous thromboembolism (VTE) prophylaxis contributes to preventable patient harm. We hypothesized that non-administration would be more common for parenteral VTE prophylaxis than oral infectious disease or cardiac prophylaxis or for treatment medications. The primary study goal was to determine if non-administration of parenteral VTE prophylaxis is more frequent than other prophylactic or treatment medications. METHODS: In this retrospective cohort study of consecutive admissions we used descriptive statistics and risk ratios (RR) to compare the number of non-administered doses of VTE prophylaxis, oral infectious disease and cardiovascular prophylaxis and treatment medications...

Infant mortality accounts for the majority of child deaths in Tanzania, and malnutrition is an important underlying cause. The objectives of this cross-sectional study were to describe the micronutrient status of infants in Tanzania and assess predictors of infant micronutrient deficiency. We analyzed serum vitamin D, vitamin B12, folate, and ferritin levels from 446 infants at two weeks of age, 408 infants at three months of age, and 427 mothers three months post-partum. We used log-Poisson regression to estimate relative risk of being deficient in vitamin D and vitamin B12 for infants in each age group...

BACKGROUND: The long-term impact of pneumococcal conjugate vaccines on pneumonia hospitalizations in all age-groups varies between countries. In the Netherlands, the 7-valent pneumococcal conjugate vaccine (PCV7) was implemented for newborns in 2006 and replaced by PCV10 in 2011. We assessed the impact of PCVs on community-acquired pneumonia (CAP) hospitalization rates in all age-groups. METHODS: A time series analysis using Poisson regression was performed on 155,994 CAP hospitalizations...

Studies investigating the impact of medical marijuana legalization have found no significant changes in adolescent use. In one of the few studies focused on recreational marijuana, we investigated how recreational marijuana legalization and community sales policy influenced factors that likely impact youth use (youth willingness and intent to use, parent use) as well as youth use. Legalization of recreational marijuana in Oregon coincided with our study on adolescent substance use. Cohort 1 transitioned from 8th to 9th grade prior to legalization and Cohort 2 made this transition during legalization (N = 444; 53% female)...

BACKGROUND: Infliximab (IFX) infusion may lead to development of anti-IFX antibodies, and subsequent infusion reactions (IRs). The safety of rapid IFX infusion administered over 60 minutes has been under-investigated in children with inflammatory bowel disease. In a multicenter study, the frequency and nature of rapid infusion-associated IRs were examined. METHODS: The medical records of all consecutive children with inflammatory bowel disease receiving rapid IFX infusions between January 2014 and December 2016 were reviewed...

BACKGROUND: Kawasaki disease (KD) is an acute febrile vasculitis which primarily affects children. The etiology of KD is unknown: while certain characteristics of the disease suggest an infectious origin, genetic or environmental factors may also be important. Seasonal patterns of KD incidence are well-documented, but it is unclear whether these patterns are caused by changes in climate or by other unknown seasonal effects. METHODS: The relationship between KD incidence and deviations from expected temperature and precipitation were analyzed using KD incidence data from Japanese nationwide epidemiological surveys (1991-2004) and climate data from 136 weather stations of the Japan Meteorological Agency...

Purpose People with HIV infection have an elevated risk of anal cancer. However, recent calendar trends are incompletely described, and which population subgroups might benefit from cancer screening is unknown. Methods We used linked data from HIV and cancer registries in nine US areas (1996 to 2012). We calculated standardized incidence ratios to compare anal cancer incidence in people with HIV infection with the general population, used Poisson regression to evaluate anal cancer incidence among subgroups of people with HIV and to assess temporal trends, and estimated the cumulative incidence of anal cancer to measure absolute risk...
