Objective: To assess the evidence presented in a set of articles that use the Canadian Maternal–Infant Research on Environmental Chemicals (MIREC) study database to claim that community water fluoridation (CWF) is associated with harm to foetal and infant cognitive development. Methods: Critical appraisal of measurements and processes in the MIREC database, and articles derived therefrom. MIREC's cohort is approximately 2000 pregnant women recruited in 10 centres across Canada, 2008–2011, leading to measuring 512 children aged 3–6 years in six cities. Fluoride exposure was measured by city fluoridation status, self‐reports and maternal spot urine samples. Intelligence Quotient (IQ) was measured using the Wechsler Preschool and Primary Scale of Intelligence (WPPSI‐III) by different assessors in each city. Results: MIREC's fluoride and IQ measurements are invalid and therefore cannot support the claim that CWF is associated with IQ decline in children. Conclusions: The MIREC fluoride‐IQ articles' results should be considered unacceptable for legal and policy purposes; other water fluoridation studies and systematic reviews show no effect of fluoridation on cognition.

While launching a campaign to eliminate cervical cancer, the World Health Organization called to halt human papillomavirus (HPV) gender-neutral vaccination (GNV) because of limited vaccine supply, raising ethical and legal questions about female-only vaccination versus GNV. We identified ethical and legal aspects of HPV GNV by searching MEDLINE for records up to February 19, 2021. We also provided an overview of HPV vaccines, the evolution of HPV vaccine recommendations in North America, and a timeline of male HPV vaccination introduction by searching PubMed, Google, and government websites. Four HPV vaccines are available: Cervarix, Gardasil, Gardasil9, and Cecolin. Vaccine recommendations in North America evolved from female only to eventually include males. Following the FDA's approval of the first HPV vaccine for males (2009), 35 countries began vaccinating males (2011-2020). On the basis of 59 eligible records out of 652, we identified the following constructs: lower male awareness of HPV and vaccination (n = 13), limited economic resources (n = 5), shared social responsibility (n = 18), unprotected groups from female-only HPV vaccination (n = 10), limited screening for HPV-associated noncervical cancers (n = 6), consideration of ethical principles (n = 17), and HPV vaccine mandates (n = 5). Ethical and legal aspects must be considered when recommending vaccination for females only or GNV. [ABSTRACT FROM AUTHOR]

Background: Compassion fatigue is recognized as impacting the health and effectiveness of healthcare providers, and consequently, patient care. Compassion fatigue is distinct from "burnout." Reliable measurement tools, such as the Professional Quality of Life scale, have been developed to measure the prevalence, and predict risk of compassion fatigue. This study reviews the prevalence of compassion fatigue among healthcare practitioners, and relationships to demographic variables. Methods: A systematic review was conducted using key words in MEDLINE, PubMed, and Ovid databases. Data were extracted from a total of 71 articles meeting inclusion criteria, from studies measuring compassion fatigue in healthcare providers using a validated instrument. Quantitative and qualitative data were extracted and compiled by three independent reviewers into an evidence table that included basic study characteristics, study strength and quality determination, measurements of compassion fatigue, and general findings. Meta-analysis, where data allowed, was stratified by Professional Quality of Life version, heterogeneity was quantified, and pooled means were reported with 95% confidence interval. A table of major study characteristics and results was created. Ethical consideration: This paper contains no primary data obtained directly from research participants. Data obtained from previously published resources have been acknowledged within references. Psychological distress, particularly compassion fatigue, can be insidious, no health profession is immune, and may significantly impact the ability to provide care. Results: A total of 71 studies were included. Compassion fatigue was reported across all practitioner groups studied. Relationships to most demographic variables such as years of experience and specialty were either not statistically significant or unclear. Variability in reporting of Professional Quality of Life results was found. Interpretation: Compassion fatigue exists across diverse practitioner groups. Prevalence is highly variable, and its relationship with demographic, personal, and/or professional variables is inconsistent. Questions are raised about how to mitigate compassion fatigue.
