The archaic definition and registration processes for stillbirth currently prevalent in Canada impede both clinical care and public health. The situation is fraught because of definitional problems related to the inclusion of induced abortions at ≥20 weeks' gestation as stillbirths widespread uptake of prenatal diagnosis and induced abortion for serious congenital anomalies has resulted in an artefactual temporal increase in stillbirth rates in Canada and placed the country in an unfavourable position in international (stillbirth) rankings. Other problems with the Canadian stillbirth definition and registration processes extend to the inclusion of fetal reductions (for multi-fetal pregnancy) as stillbirths, and the use of inconsistent viability criteria for reporting stillbirth. This paper reviews the history of stillbirth registration in Canada, provides a rationale for updating the definition of fetal death and recommends a new definition and improved processes for fetal death registration. The recommendations proposed are intended to serve as a starting point for reformulating issues related to stillbirth, with the hope that building a consensus regarding a definition and registration procedures will facilitate clinical care and public health.The COVID-19 pandemic is bringing about far-reaching structural changes on both the economy and public health, and conventional methodologies have to be fine-tuned to assist public health decision making. In this context, behavioural economics, which is situated at the crossroads between economics and social psychology, is an undeniably innovative field. In contrast with conventional models, the economic models of behavioural economics incorporate psychological and social determinants to produce more accurate predictions of individual behaviour. In the last 20 years, the scientific community has been using this approach's quantitative tool, experimental economics, in many areas of health, including prevention, promotion, human resources and social signage. Studies have come up with effective solutions that have improved best public health practices and provided sources of inspiration that should not be overlooked in the fight against COVID-19. They have allowed natural human behaviour to take a central role again, helped us to understand how the social and economic environment influences individuals, and enabled us to anticipate human reactions and so make faster adjustments to public policies.
To assess health equity-oriented COVID-19 reporting across Canadian provinces and territories, using a scorecard approach.

A scan was performed of provincial and territorial reporting of five data elements (cumulative totals of tests, cases, hospitalizations, deaths, and population size) across three units of aggregation (province or territory level, health regions, and local areas) (15 "overall" indicators), and for four vulnerable settings (long-term care and detention facilities, schools, and homeless shelters) and eight social markers (age, sex, immigration status, race/ethnicity, healthcare worker status, occupational sector, income, and education) (180 "equity-related" indicators) as of December 31, 2020. Per indicator, one point was awarded if case-delimited data were released, 0.7 points if only summary statistics were reported, and 0 if neither was provided. Results were presented using a scorecard approach.

Overall, information was more complete for cases and deaths than for tests, hospitalizallow for this pandemic and future ones.
One year into the pandemic, socially stratified reporting for COVID-19 outcomes remains sparse in Canada. However, several "best practices" in health equity-oriented reporting were observed and set a relevant precedent for all jurisdictions to follow for this pandemic and future ones.Cone photoreceptors provide the foundation of most of human visual experience, but because they are smaller and less numerous than rods in most mammalian retinas, much less is known about their physiology. We describe new techniques and approaches which are helping to provide a better understanding of cone function. We focus on several outstanding issues, including the identification of the features of the phototransduction cascade that are responsible for the more rapid kinetics and decreased sensitivity of the cone response, the roles of inner-segment voltage-gated and Ca2+-activated channels, the means by which cones remain responsive even in the brightest illumination, mechanisms of cone visual pigment regeneration in constant light, and energy consumption of cones in comparison to that of rods.Recent studies have linked carbonyl stress to many physiological processes. Increase in the levels of carbonyl compounds, derived from both endogenous and exogenous sources, is believed to accompany normal age-related decline as well as different pathologies. Reactive carbonyl species (RCS) are capable of damaging biomolecules via their involvement in a net of nonspecific reactions. In the advanced stages of RCS metabolism, variety of poorly degraded adducts and crosslinks, collectively named advanced glycoxidation end products (AGEs), arises. They are accumulated in an age-dependent manner in different tissues and organs and can contribute to inflammatory processes. In particular, detrimental effects of the end products are realized via activation of the specific receptor for AGEs (RAGE) and RAGE-dependent inflammatory signaling cascade. Although it is unclear, whether carbonyl stress is causal for age-associated impairments or it results from age- and disease-related cell damages, increased levels of RCS and AGEs are tightly related to inflammaging, and therefore, attenuation of the RAGE signaling is suggested as an effective approach for the treatment of inflammation and age-related disorders. The question raised in this review is whether specific metabolism in the aging brain related to carbonyl/RCS/AGE/RAGE stress.Under-detection of HIV/AIDS still burdens many low- and middle-income countries (LMICs). read more Our randomized trial investigated the effects of financial incentives and a behavioral nudge to induce HIV testing and learning HIV status in Ecuador. In the control group, 12.2% of participants agreed to testing, and 5.3% learned results. A financial incentive paid at testing increased the fraction of participants tested by 50.1 percentage points (95% CI 38.8 to 61.4) and the fraction who learned their status by 8.9 percentage points (95% CI 5.3 to 12.5); the nudge had no effect. The HIV-positive rate was 1.2% in the control group, and incentives prompted a 4.7 percentage point (95% CI 0.5 to 8.9) higher proportion of HIV-positive detection. Incentives also induced earlier testing, suggesting reduced procrastination. This suggests that information with appropriately timed small financial incentives can improve HIV testing and detection of new cases in the general population in LMIC settings.
