Expression of HLA Class I Antigen, Aspirin Use, and Survival After a Diagnosis of Colon Cancer

IMPORTANCE Use of aspirin (which inhibits platelet function) after a colon cancer diagnosis is associated with improved overall survival. Identifying predictive biomarkers of this effect could individualize therapy and decrease toxic effects. OBJECIVE To demonstrate that survival benefit associated with low-dose aspirin use after a diagnosis of colorectal cancer might depend on HLA class I antigen expression

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

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

Statin treatment and the risk of recurrent pulmonary embolism

AIMS: Patients with idiopathic venous thromboembolism (VTE) have a high recurrence risk during and after stopping anticoagulant treatment. Several studies suggest that treatment with statins reduces the incidence of a first episode of VTE, but dataon the effects in patients with a previous episode are lacking

OBJECTIVES: To assess survival in relation to aspirin use after diagnosis in older adults with colon cancer. DESIGN: Subgroup analysis of a previously published cohort and retrospective study. SETTING: Individuals registered in the Eindhoven CancerRegistry (ECR) between 1998 and 2007, linked to prescriptions of low-dose aspirin (80 mg) registered in a community pharmacy database

Use of Aspirin postdiagnosis improves survival for colon cancer patients

Background:The preventive role of non-steroid anti-inflammatory drugs (NSAIDs) and aspirin, in particular, on colorectal cancer is well established. More recently, it has been suggested that aspirin may also have a therapeutic role. Aim of the presnt observational population-based study was to assess the therapeutic effect on overall survival of aspirin/NSAIDs as adjuvant treatment used after the diagnosis of colorectal cancer patients

Recurrence of urinary tract infections in postmenopausal diabetic women using different antibiotics

Objectives: Postmenopausal women with diabetes mellitus (DM) have an increased incidence of urinary tract infections (UTI) compared to women without DM. The aim of this study is to compare recurrence rates of UTI in postmenopausal women with DM aftr treatment with nitrofurantoin, the agent of first choice following the Dutch guidelines, with two other common prescribed antibiotics trimethoprim and norfloxacin

Lower risk of cancer in patients on metformin in comparison with those on sulfonylurea derivatives: results from a large population-based follow-up study

OBJECTIVE: Numerous studies have suggested a decreased risk of cancer in patients with diabetes on metformin. Because different comparison groups were used, the effect magnitude is difficult to estimate. Therefore, the objective of this study was tfurther analyze whether, and to what extent, use of metformin is associated with a decreased risk of cancer in a cohort of incident users of metformin compared with users of sulfonylurea derivatives
