beta-Blocker use and all-cause mortality of melanoma patients: results from a population-based Dutch cohort study

BACKGROUND: Results from preclinical and observational studies suggest that beta-adrenoreceptor inhibition might influence disease progression of melanoma. PATIENTS AND METHODS: Patients 18years with cutaneous melanoma (Breslow thickness >1mm) regitered in the Eindhoven Cancer Registry between January 1, 1998 and December 31, 2010, who were also registered with PHARMO record linkage system (RLS), were eligible

Persisting gender differences and attenuating age differences in cardiovascular drug use for prevention and treatment of coronary heart disease, 1998-2010

BACKGROUND: Evidence on recent time trends in age-gender differences in cardiovascular drug use is scarce. We studied time trends in age-gender-specific cardiovascular drug use for primary prevention, secondary prevention, and in-hospital treatmentof coronary heart disease. METHODS AND RESULTS: The PHARMO database was used for record linkage of drug dispensing, hospitalization, and population data to identify drug use between 1998 and 2010 in 1 203 290 persons >/=25 years eligible for primary prevention, 84 621 persons hospitalized for an acute coronary syndrome (ACS), and 15 651 persons eligible for secondary prevention

Ineffectiveness and adverse events of nitrofurantoin in women with urinary tract infection and renal impairment in primary care

PURPOSE: To determine whether treatment with nitrofurantoin in women with urinary tract infection (UTI) and renal impairment in primary care is associated with a higher risk of ineffectiveness and/or serious adverse events than in women without renl impairment. METHODS: A cohort of 21,317 women treated with nitrofurantoin and a cohort of 7,926 women treated with trimethoprim, identified from the Pharmo Record Linkage System, were analysed

Real-life compliance and persistence among users of subcutaneous and sublingual allergen immunotherapy

BACKGROUND: Subcutaneous allergen immunotherapy (SCIT) and sublingual allergen immunotherapy (SLIT) are safe and effective treatments of allergic rhinitis, but high levels of compliance and persistence are crucial to achieving the desired clinicalffects. OBJECTIVE: Our objective was to assess levels and predictors of compliance and persistence among grass pollen, tree pollen, and house dust mite immunotherapy users in real life and to estimate the costs of premature discontinuation
