Pharmacy in transition: A work sampling study of community pharmacists using smartphone technology

Introduction

The nature of community pharmacy is changing, shifting from the preparation and distribution of medicines to the provision of cognitive pharmaceutical services (CPS); however, often the provision of traditional services leaves little time for innovative services. This study investigated the time community pharmacists spend on the tasks and activities of daily practice and to what extent they are able to implement CPS-related services in daily practice.

Heightened hypocrisy: a critical analysis of how the alcohol industry-sponsored ‘‘Nigerian Beer Symposium’’ jeopardises public health

This paper analyses how an alcohol industry-sponsored ‘Nigerian Beer Symposium’ (NBS) could endanger public health. The NBS, an annual one-day symposium, sponsored by Heineken-Nigerian Breweries, was recently introduced to create awareness of the ‘health and nutritional benefits of beer consumption’. Amongst other resource persons, Heineken-Nigerian Breweries contracts professors, medical doctors, nutritionists, advertisers, and celebrities from Africa and Europe to discuss the health and nutritional benefits of beer consumption. While all of the speakers strategically focused on the health and nutritional benefits of beer consumption, a few, in passing, mentioned drinking in moderation. In particular, male speakers focused on how beer prevents cancer, reduces the incidence of kidney stones, enhances vitality and cardiovascular health, and facilitates longevity and cognition among the aged. The female speakers encouraged women to consume beer because it enhances vitality and improves skin/physical beauty. Overall, none of the speakers specifically mentioned the consequences of alcohol (mis)use. This paper argues that the NBS is strategically organised to encourage beer initiation and/or high consumption, which will increase the sponsor’s profit. By providing biased information about the purported health and nutritional benefits of beer, the NBS will mislead the public, leading to more alcohol-related problems in Nigeria. Therefore, NBS should be regulated by implementing WHO-recommended alcohol policies in Nigeria.     

Industry Funding Is Correlated With Publication Productivity of US Academic Radiation Oncologists

Purpose

Industry payments to physicians are financial conflicts of interest and may influence research findings and medical decisions. We aim to (1) characterize industry payments within radiation oncology; and (2) explore the potential correlation between receiving disclosed industry payments and academic productivity.

Association of gBRCA1/2 mutation locations with ovarian cancer risk in Japanese patients from the CHARLOTTE study

Whether germline (g) breast cancer susceptibility gene (BRCA) mutations are located within or outside the ovarian cancer cluster region (OCCR) (1380‐4062 bp for gBRCA1, and between 3249‐5681 bp and 6645‐7471 bp for gBRCA2) may influence risk variations for ovarian cancers. This ad hoc analysis of the CHARLOTTE epidemiological study in Japan assessed the distribution of gBRCA1/2 mutations in patients with newly diagnosed ovarian cancer, and investigated an association between gBRCA1/2 mutation locations and ovarian cancer risk. Differences in patient background and clinical characteristics in subgroups stratified by gBRCA1/2 mutation locations were also evaluated. We analyzed the data of 93 patients (14.7%) from the CHARLOTTE study who were positive for gBRCA1/2 mutations. After excluding 16 cases with L63X founder mutation, 28 (65.1%) of gBRCA1 mutations were within the OCCR. Of 30 gBRCA2 mutations, 15 (50.0%) were within the OCCR. Of 27 patients (one patient excluded for unknown family history) with gBRCA1 mutations located in the OCCR, 11 (40.7%) had a family history of ovarian cancer; the proportion of patients with a family history of ovarian cancer and gBRCA1 mutations outside the OCCR was lower (13.3%). Sixty percent of patients with gBRCA1 mutations outside the OCCR had a family history of breast cancer; the proportion of patients with a family history of breast cancer and gBRCA1 mutations within the OCCR was relatively lower (33.3%). Understanding the mutation locations may contribute to more accurate risk assessments of susceptible individuals and early detection of ovarian cancer among gBRCA mutation carriers.
