Community pharmacists' evolving role in Canadian primary health care: a vision of harmonization in a patchwork system.

Canada's universal public health care system provides physician, diagnostic, and hospital services at no cost to all Canadians, accounting for approximately 70% of the 264 billion CAD spent in health expenditure yearly. Pharmacy-related services, including prescription drugs, however, are not universally publicly insured. Although this system underpins the Canadian identity, primary health care reform has long been desired by Canadians wanting better access to high quality, effective, patient-centred, and safe primary care services.

Pupillary response: cognitive effort for breast cancer survivors.

Purpose: The purpose of this cross-sectional comparative pilot study was to evaluate cognitive effort, indexed by pupillary response (PR), for breast cancer survivors (BCS) with complaints of cognitive dysfunction following chemotherapy.

Study Aims: Compare the cognitive effort employed by BCS to healthy controls (HC) during neuropsychological tests (NPT) for memory, sustained attention, verbal fluency, visuospatial ability, processing speed and executive function; and Investigate the relationship between PR-indexed cognitive effort and participants' self-report of cognitive function.

Methods: Self-report of cognitive function was collected from 23 BCS and 23 HC.

Informing antimicrobial stewardship: factors associated with inappropriate antimicrobial prescribing in primary care.

Background: Antimicrobial stewardship (AS) programs promote the optimal use of antimicrobials and safe patient care. With most antimicrobials prescribed in the ambulatory setting, establishing benchmark data is imperative to gauge the impact of future AS initiatives.

Objectives: To determine the frequency of potentially inappropriate antimicrobial prescribing in primary care practices in Manitoba, Canada and to assess the association between potentially inappropriate antimicrobial prescribing and patient, prescriber and practice-related factors.

Pharmacological response sensitization in nerve cell networks exposed to the antibiotic gentamicin.

Gentamicin is an aminoglycoside antibiotic that is used in clinical, organismic, and agricultural applications to combat gram-negative, aerobic bacteria. The clinical use of gentamicin is widely linked to various toxicities, but there is a void in our knowledge about the neuromodulatory or neurotoxicity effects of gentamicin. This investigation explored the electrophysiologic effects of gentamicin on GABAergic pharmacological profiles in spontaneously active neuronal networks in vitro derived from auditory cortices of E16 mouse embryos and grown on microelectrode arrays.

An unexpected disruption of the atmospheric quasi-biennial oscillation.

One of the most repeatable phenomena seen in the atmosphere, the quasi-biennial oscillation (QBO) between prevailing eastward and westward wind jets in the equatorial stratosphere (approximately 16 to 50 kilometers altitude), was unexpectedly disrupted in February 2016. An unprecedented westward jet formed within the eastward phase in the lower stratosphere and cannot be accounted for by the standard QBO paradigm based on vertical momentum transport. Instead, the primary cause was waves transporting momentum from the Northern Hemisphere.

Assessing prescribing of NSAIDs, antiplatelets, and anticoagulants in Canadian family medicine using chart review.

Background Drug-related problems have been identified as a major contributor to emergency room visits, hospitalizations, and death. The most commonly implicated medications are nonsteroidal anti-inflammatory drugs (NSAIDs), antiplatelets, and anticoagulants. Considering a significant proportion of these harms are preventable, indicators to identify risky prescribing before they lead to harm have been developed.

High risk use of OTC NSAIDs and ASA in family medicine: A retrospective chart review.

Background: Complications associated with the use of NSAIDs, antiplatelet agents, and anticoagulants are among the top causes of preventable drug-related ER visits, hospitalizations and death. Although over-the-counter (OTC) NSAIDs and ASA also contribute to this preventable risk, it is unclear how well these medications are documented in primary care records.

Methods: A retrospective electronic and paper chart review was conducted to evaluate the prevalence of 13 evidence-based high-risk prescriptions and the contribution of OTC NSAIDs and ASA to these potentially inappropriate prescriptions (PIPs).

Weakened stratospheric quasibiennial oscillation driven by increased tropical mean upwelling.

The zonal wind in the tropical stratosphere switches between prevailing easterlies and westerlies with a period of about 28 months. In the lowermost stratosphere, the vertical structure of this quasibiennial oscillation (QBO) is linked to the mean upwelling, which itself is a key factor in determining stratospheric composition. Evidence for changes in the QBO have until now been equivocal, raising questions as to the extent of stratospheric circulation changes in a global warming context.
