Abstract
PURPOSE We quantified the joint evolution of sleep duration and screen time between 2018 and 2022 in a large sample of adolescents from Quebec, Canada, to ascertain changes that occurred during the COVID-19 pandemic. METHODS A natural experiment design was used to compare variations from year to year and in association with the pandemic outbreak. Using structural equation modeling on data collected between 2018 and 2022 among adolescents attending 63 high schools, we analyzed the joint evolution of sleep duration and screen time while adjusting for previous year values, concurrent flourishing score, sex, age, and family level of material deprivation. RESULTS A total of 28,307 adolescents, aged on average 14.9 years, were included in the analyses. Between 2019 and 2022, sleep duration increased by 9.6 (5.7, 13.5) minutes and screen time by 129.2 (120.5, 138.0) minutes on average. In 2022, the adolescents spent almost equal amounts of time sleeping and using screens. Lower flourishing scores were associated with shorter sleep duration and lengthier screen time. Girls' screen time became similar to boys' over time. DISCUSSION Adolescents now spend almost equal amounts of time sleeping and using screens, a situation that calls for urgent public health actions. These findings highlight the importance of tracking changes in adolescents' behaviours over time, to design and implement interventions adapted to the changing health needs of different groups.

Abstract
PURPOSE There is concern over the potentially detrimental impact of the COVID-19 pandemic on adolescents' mental health. We examined changes in depression and anxiety symptoms from before (2018-19) to the early (2019-20) and ongoing pandemic (2020-21) responses among Canadian adolescents in the context of a natural experiment. METHODS We used linked survey data from 5,368 Canadian secondary school students who participated in three consecutive waves of the cannabis use, obesity, mental health, physical activity, alcohol use, smoking, and sedentary behaviour study during the 2018-19, 2019-20, and 2020-21 school year. Separate fixed effects models examined whether changes in depression (Center for Epidemiologic Studies Depression Scale Revised-10) and anxiety (General Anxiety Disorder-7) symptoms differed between two cohorts. The cohorts differed in the timing of their second data collection wave; one cohort participated before the pandemic and the other cohort participated in the early pandemic (spring 2020). RESULTS Depression and anxiety symptoms increased during the early and ongoing pandemic periods in the overall sample and both cohorts. The two cohorts experienced similar elevations in their symptoms. Females and younger respondents presented greater elevations over time. The proportion of adolescents with significant depressive (29.4%) and moderate-to-severe anxiety (17.6%) symptoms at baseline increased by 1.5 times, reaching 44.8% and 29.8% in the ongoing pandemic period, respectively. DISCUSSION Findings suggest that internalizing symptoms have consistently increased since before the onset of COVID-19, particularly in the ongoing pandemic period; however, we found no evidence of the increase being due to the pandemic in the early COVID-19 period when comparing the two cohorts. Ongoing evaluation of adolescents' mental health is necessary to capture potentially dynamic impacts over time.

Abstract
BACKGROUND Recent studies suggest that the risk of SARS-CoV-2 infection may be greater in more densely populated areas and in cities with a higher proportion of persons who are poor, immigrant, or essential workers. This study examines spatial inequalities in SARS-CoV-2 exposure in a health region of the province of Quebec in Canada. METHODS The study was conducted on the 1206 Canadian census dissemination areas in the Capitale-Nationale region of the province of Quebec. The observation period was 21 months (March 2020 to November 2021). The number of cases reported daily in each dissemination area was identified from available administrative databases. The magnitude of inequalities was estimated using Gini and Foster-Greer-Thorbecke (FGT) indices. The association between transmission and socioeconomic deprivation was identified based on the concentration of transmission in socially disadvantaged areas and on nonparametric regressions relating the cumulative incidence rate by area to ecological indicators of spatial disadvantage. Quantification of the association between median family income and degree of exposure of dissemination areas was supplemented by an ordered probit multiple regression model. RESULTS Spatial disparities were elevated (Gini = 0.265; 95% CI [0.251, 0.279]). The spread was more limited in the less densely populated areas of the Quebec City agglomeration and outlying municipalities. The mean cumulative incidence in the subsample made up of the areas most exposed to the pandemic was 0.093. The spread of the epidemic was concentrated in the most disadvantaged areas, especially in the densely populated areas. Socioeconomic inequality appeared early and increased with each successive pandemic wave. The models showed that areas with economically disadvantaged populations were three times more likely to be among the areas at highest risk for COVID-19 (RR = 3.55; 95% CI [2.02, 5.08]). In contrast, areas with a higher income population (fifth quintile) were two times less likely to be among the most exposed areas (RR = 0.52; 95% CI [0.32, 0.72]). CONCLUSION As with the H1N1 pandemics of 1918 and 2009, the SARS-CoV-2 pandemic revealed social vulnerabilities. Further research is needed to explore the various manifestations of social inequality in relation to the pandemic.

Abstract
BACKGROUND Birthweight and gestational age are important factors of not only newborn health by also child development and can contribute to delayed cognitive abilities. However, no study has analyzed the association of birthweight and gestational age with school trajectory measured simultaneously by school entry, grade repetition, and school dropout. This study aims, first, to analyze the association of birthweight or gestational age with school entry, and second, to explore the relationship between birthweight or gestational age and grade repetition and school dropout among children in Ouagadougou, Burkina Faso. METHODS This study used longitudinal data from the Ouagadougou Health and Demographic Surveillance System. Our samples consisted of children born between 2008 and 2014 who were at least three years old at the beginning of the 2017-18 school year. Samples included 13,676, 3152, and 3498 children for the analysis of the school entry, grade repetition, and dropout, respectively. A discrete-time survival model was used to examine the relationship between birthweight or gestational age and school entry, grade repetition, and dropout. The association between birthweight or gestational age and age at school entry were assessed using a Poisson regression. RESULTS The incidence rate of school entry was 18.1 per 100 people-years. The incidence of first repetition and dropout were 12.6 and 5.9, respectively. The probability of school entry decreased by 31% (HR:0.69, 95%CI: 0.56-0.85) and 8% (HR:0.92, 95%CI: 0.85-0.99) for children weighing less than 2000 g and those weighing between 2000 and 2499 g, respectively, compared to those born with a normal weight (weight ≥ 2500 g). The age at school entry of children with a birthweight less than 2000 g and between 2000 and 2499 g was 7% (IRR: 1.07, 95%CI: 1.06-1.08) and 3% (IRR: 1.03, 95%CI: 1.00-1.06) higher than children born at a normal birthweight, respectively. Gestational age was not associated with school entry or age at school entry. Similarly, birthweight and gestational age were not associated with grade repetition or dropout. CONCLUSION This study shows that low birthweight is negatively associated with school entry and age at school entry in Ouagadougou. Efforts to avoid low birthweights should be part of maternal and prenatal health care because the associated difficulties may be difficult to overcome later in the child's life. Further longitudinal studies are needed to better understand the relationship between development at birth and school trajectory.

Abstract
AIM To review evidence of the effects of stunting, or height-for-age, on schooling level and schooling trajectories, defined as the combination of school entry age, grade repetition, and dropouts. METHODS We conducted a systematic review of studies (last update March 20, 2021) that assessed the association between stunting, or height-for-age, and at least one component of school trajectory using five databases (PubMed, Embase, Education Resources Information Center (ERIC), Web of Science and PsycINFO). Two independent reviewers performed study selection and data extraction. Pooled effects were calculated using the generic inverse variance weighting random effect model. The risk of bias was assessed using the ROBINS-I tool. PROSPERO ID CRD42020198346. RESULTS We screened 3944 articles and 16 were eligible for the qualitative and quantitative synthesis. Meta-analysis showed that an increase in height-for-age leads to an increase in early enrollment [OR=1.34 (95% CI, 1.07-1.67)], a reduction in late enrollment [OR=0.63 (95% CI, 0.51-0.78)], an increase in schooling level [MD=0.24 (95% CI, 0.14-0.34)], and a reduction of school overage [OR=0.79 (95% CI, 0.70-0.90)]. Stunted children were more likely to repeat a grade than non-stunted [OR=1.59 (95% CI, 1.18-2.14). CONCLUSION This review suggests that stunting in childhood might negatively affect school trajectories. Future research should evaluate the effect of stunting on school trajectories and the modification effect of socioeconomic status.

Abstract
Teenagers' vaccination has become crucial to limit the COVID-19 transmission in the population. To increase the vaccination rate of this age group, a school-based vaccination campaign was launched in Québec, Canada from June 7 to 18, 2021. This study aimed to analyze trajectories of vaccination coverage over time among students attending 37 high schools. The study explored whether school-based vaccination campaigns contributed to the progression of the vaccination coverage and attenuated disparities in vaccination coverage across schools. On average, first dose coverage quickly increased from 30.6% to 81.5% between June 6 and 18, 2021, after the launch of the campaign. As of August 13, 2021, first dose coverage had reached 87.9% and 64.9% for the second dose coverage. Public schools with poorer student populations had 6.5 points of percentage lower first dose vaccination rates (95%CI 0.3%; 12.6%) compared to other schools. A higher level of concern related to the pandemic among students was associated with a 4.3 points of percentage increased coverage (95%CI 0.7%; 8.0%). The initial uneven distribution in first dose coverage decreased dramatically by the end of the campaign. Similar trends were observed for the second dose, although between schools' inequality at the end of the period of observation was significantly larger. The school-based vaccination campaign might have initially contributed to a prompt rise in vaccination coverage and helped the disadvantaged schools to reach similar vaccination coverage as seen in other schools. In addition to being an efficient way to achieve rapidly high vaccination coverage, the school-based approach might contribute to increase equity in vaccination distribution.

Abstract
BACKGROUND Adolescence is a critical period for vaping onset. The purpose of this article was to examine the effect of the early stages of the COVID-19 pandemic period on youth vaping. METHODS We used 3-year linked data from the COMPASS study, including 7585 Canadian (Quebec, Ontario) adolescents from which 1949 completed all three survey waves (pre-COVID-19 [2018, 2019] and online [2020] during the early pandemic period [May-July 2020]) and provided vaping data. Structural equation modeling (SEM) and difference-in-difference (DD) models were used to estimate pre-COVID-19 to initial COVID-19 pandemic period change (2019-2020) in vaping (monthly, weekly, daily) compared with 2018-2019 change to adjust for age-related effects. Models were adjusted for age of entry into the cohort and sociodemographic characteristics. RESULTS In the SEM and DD models, the proportion of youth who were monthly and weekly vaping increased from 2018 to 2019 but decreased from 2019 to 2020; daily vaping increased across all waves. However, for all vaping outcomes modeled, the expected increases from the pre-COVID-19 wave (2019) to the initial COVID-19 period wave (2020) were lesser relative to the changes seen across the 2018 to 2019 waves. CONCLUSION The early stages of the COVID-19 pandemic period appear to be associated with a reduction in the proportion of youth who were monthly and weekly vapers in our adjusted longitudinal models. While daily vaping increased over this same period of time, the magnitude of the increase in our adjusted longitudinal models appears attenuated by the early stages of the pandemic. IMPLICATIONS This large prospective study of youth that included pre-pandemic data is unique in that we were able to identify that the early stages of the COVID-19 pandemic period was associated with a reduction in the proportion of youth who were monthly and weekly vapers in our adjusted longitudinal models. Conversely, the proportion of youth who were daily vaping increased over this same period of time, but the magnitude of the increase appears smaller than expected during the early stages of the pandemic in our adjusted longitudinal models. This study provides novel robust evidence that the patterns of vaping most aligned with onset and progression (i.e., monthly and weekly use) appear attenuated during the initial pandemic period.

Abstract
Understanding risky sexual behaviors among adolescents is key in efforts devoted to reducing the health burden related to sexually transmitted infections and unintended or unplanned pregnancies. The aims of this study were to understand the association between number of lifetime sexual partners and time since sexual debut (TSSD) among adolescents and to determine whether sex modified this association. Data were drawn from the 2018-2019 COMPASS-Quebec study, a cohort study conducted in secondary schools in the province of Quebec, Canada. Of 18,467 respondents aged 14 years and older, 6991 (37.9%; mean age 15.3) reported consensual sexual intercourse and answered questions on their age at sexual initiation and number of lifetime sexual partners. Multilevel Poisson regressions with robust standard errors were estimated to adjust for covariates and produce adjusted group mean differences. The adjusted mean number of lifetime sexual partners ranged from 1.5 for those who had recently begun sexual activity (< 12 months) to 4.0 for those who had been active for > 35 months, an average rise of about 0.6 per year. Females-to-males adjusted mean differences showed that males reported more sexual partners than females at all time points, but the differences were only significant at the shorter (< 12 months) and longer (> 35 months) time spans. This study highlights the importance of taking into account TSSD when using and interpreting the number of lifetime sexual partners as risky sexual behavior among adolescents. Sex did not have a significant modifying effect on the relationship between number of lifetime sexual partners and TSSD.

Abstract
INTRODUCTION The objectives of this study were to explore the extent to which adolescents adopted COVID-19 preventive measures in the first few months of the pandemic and to understand their adoption by looking at interconnected adoption-related factors and determining the strength of these factors, particularly among subgroups not expected to be early adopters. METHODS Analyses focus on data collected during Spring 2020 from 29 eastern Quebec secondary schools that participated in the COMPASS study. Participants (n = 6052) self-reported their knowledge, perception of risk and preventive practices to do with the COVID-19 pandemic. Data were analyzed using structural equation models based on gender and anxiety level. RESULTS The majority of respondents reported adopting the recommended COVID-19 preventive measures. The results showed three paths leading to adolescents' adoption of these measures: pandemic knowledge; perception of risk related to COVID-19; and, in particular, discussions with relatives about preventive measures and what to do in case of infection. CONCLUSIONS While most of the adolescent participants in this study appeared to comply with COVID-19 preventive measures, factors such as discussions with relatives emerge as elements to foster in order to improve adolescents' adoption of preventive measures.

Abstract
PURPOSE The impact of the COVID-19 pandemic on adolescent mental health is a global concern; however, most research is cross-sectional or started after the pandemic response began and thus unable to evaluate within-individual change. The purpose of this prospective study was to evaluate the effect of the initial COVID-19 response on adolescent mental health and ill-health as a natural experiment. METHODS We used 3-year linked data from the COMPASS study, including 7,653 Canadian (Quebec, Ontario) adolescents from which 2,099 completed surveys in all three waves (pre-COVID-19 [2018 and 2019] and online [May-July 2020], 2-3 months into the pandemic). A structural equation modeling approach to fixed effects and a difference-in-differences design were used to estimate pre-COVID-19-to-early lockdown change in mental health (psychosocial well-being [flourishing-reverse scored]) and ill-health (depression and anxiety symptoms), compared with 2018-to-2019 change. Models were adjusted for self-selection, age of entry into the cohort, and sociodemographics. RESULTS Depression, anxiety, and reverse-flourishing scores increased across all waves; however, the mental health changes from the pre-COVID-19 wave (2019) to 2020 were not greater relative to the changes seen across the 2018-to-2019 waves. CONCLUSIONS Our results do not support a detrimental effect of the initial stages of the COVID-19 lockdown measures on adolescent mental health. The deterioration in mental health in the early COVID-19 response was less than the decline found over a prepandemic period. Further prospective research is needed to explore the impact of the prolonged pandemic and related measures on adolescents and inequitable effects in population subgroups.

Abstract
CONTEXT Bisphenol A (BPA) is a ubiquitous contaminant with endocrine-disrupting effects in mammals. During chlorination treatment of drinking water, aqueous BPA can react with chlorine to form chlorinated derivatives of BPA (mono, di, tri and tetra-chlorinated derivatives) or ClxBPA. OBJECTIVE The aim of this study is to summarize and present the state of knowledge on human toxicological risk assessment of ClxBPA. MATERIALS AND METHODS A search on ClxBPA in the PubMed database was performed based on studies published between 2002 and 2021. Forty-nine studies on chlorinated derivatives of BPA were found. Available information on their sources and levels of exposure, their effects, their possible mechanisms of action and their toxicokinetics data was extracted and presented. RESULTS ClxBPA have been essentially detected in environmental aqueous media. There is evidence in toxicological and epidemiological studies that ClxBPA also have endocrine-disrupting capabilities. These emerging pollutants have been found in human urine, serum, breast milk, adipose and placental tissue and can constitute a risk to human health. However, in vitro and in vivo toxicokinetic data on ClxBPA are scarce and do not allow characterization of the disposition kinetics of these compounds. CONCLUSION More research to assess their health risks, specifically in vulnerable populations, is needed. Some water chlorination processes are particularly hazardous, and it is important to evaluate their chlorination by-products from a public health perspective.

Abstract
BACKGROUND The professional identities, profiles and representations of Burundian health workers remain insufficiently explored. Our twofold objective is to identify the different socio-professional profiles of first-line caregivers and to explore their respective representations of health workers and work. METHODS The first study describes the overall population of the 1047 staff members employed in 2014-2015 in 62 health centers. The second is a cross-sectional survey conducted in April 2014. Using IRAMUTEQ© software, we conducted textology analysis of the structure and contents of 911 respondents' representations via 3 free associations with regard to 6 questions on the "good worker" and the "what renders one capable of doing good work". RESULTS At the normative level, among all categories of staff, a relational role is a foundation of professional identity, while technical or administrative functions remain marginal. At the positional level, responses differed according to initial qualification level but not as a function of their role with patients or their professional experience. Three socio-professional categories emerged. The most qualified category (one-quarter of the population) consists primarily of male caregivers, with a high turnover rate (4 years) associated with prospects for further training and career development. These persons present the most professionalized representations of the worker and work. The second quarter has an average level of qualification and turnover (10 years), and is mainly composed of female caregivers with limited professional perspectives. This group's representations are less technical and more patient-centered. Finally, the remaining half consists of relatively low-skilled staff members in charge of technical and logistical support, who are likely to spend their entire career in the same center (>20 years). Largely disregarded by the health care system and its funders, they have few opportunities for training or advancement and despite their long experience, maintain profane representations of workers and work. CONCLUSION Our results shed light on the predicament of unskilled staff members whose expectations are rarely taken into consideration, even though they represent a significant proportion of the workforce, perform tasks essential to quality of care, and serve as bearers of the memory of their hospital center. These results also highlight the compartmentalization of practices and knowledge between categories of workers and underscore the failure of continuous training strategies targeting the unskilled.

Abstract
Background Given the high rates of cannabis use among Canadian youth and that adolescence is a critical period for cannabis use trajectories, the purpose of this paper was to examine the effect of the early stages of the COVID-19 pandemic period on youth cannabis use in the context of a natural experiment. We used 3-year linked data from the COMPASS study, including 7653 Canadian (Quebec, Ontario) adolescents from which 1937 completed all 3 survey waves (pre-COVID-19 [2018, 2019] and online [2020] during the early pandemic period [May–July 2020]). Structural equation modeling (SEM) and double difference (DD) models were used to estimate pre-COVID-19 to initial COVID-19 pandemic period change (2019–2020) in cannabis use (monthly, weekly, daily) compared to 2018 to 2019 change to adjust for age-related effects. Models were adjusted for age of entry into the cohort and sociodemographic characteristics. Results In the SEM and DD models, monthly, weekly, and daily cannabis use increased across all waves; however, the expected increases from the pre-COVID-19 wave (2019) to the initial COVID-19 period wave (2020) were lesser relative to the changes seen across the 2018 to 2019 waves. The cross-sectional data from May to July 2020 identified that the majority of youth who use cannabis did not report increased cannabis use due to COVID-19 or using cannabis to cope with COVID-19. Conclusion During the early stages of the COVID-19 pandemic period, there does not appear to be a detrimental effect on youth cannabis use, when adjusted for age-related changes. Further prospective research is needed to explore the impact of the ongoing pandemic response on youth cannabis use onset and progression.

Abstract
Canada legalized recreational cannabis use for adults on October 17, 2018 with decision-makers emphasising the need to reduce cannabis use among youth. We sought to characterise trends of youth cannabis use before and after cannabis legalization by relying on a quasi-experimental design evaluating cannabis use among high school students in Alberta, British Columbia, Ontario, and Québec who participated in the COMPASS prospective cohort study. Overall trends in use were examined using a large repeat cross-sectional sample (n = 102,685) at two time points before legalization (16/17 and 17/18 school years) and one after (18/19 school year). Further differential changes in use among students affected by legalization were examined using three sequential four-year longitudinal cohorts (n = 5,400) of students as they progressed through high school. Youth cannabis use remains common with ever-use increasing from 30.5% in 2016/17 to 32.4% in 2018/19. In the repeat cross-sectional sample, the odds of ever use in the year following legalization were 1.05 times those of the preceding year (p = 0.0090). In the longitudinal sample, no significant differences in trends of cannabis use over time were found between cohorts for any of the three use frequency metrics. Therefore, it appears that cannabis legalization has not yet been followed by pronounced changes on youth cannabis use. High prevalence of youth cannabis use in this sample remains a concern. These data suggest that the Cannabis Act has not yet led to the reduction in youth cannabis use envisioned in its public health approach.

Abstract
BACKGROUND Boys use cannabis at a younger age and more frequently than girls. It has been suggested these sex differences might vary according to students' relationship to school. We explored whether the association between sex and adolescents' cannabis use varies among schools and according to students' school connectedness. METHODS The study population consisted of all students from 11 secondary schools in the greater Québec City area. The sample included 6185 respondents in years 1 to 5 at the secondary level (equivalent to grades 7-11). Study outcomes were monthly cannabis use and early cannabis use. RESULTS The association between sex and monthly cannabis use varied significantly among schools after controlling for students' main characteristics and school socioeconomic environment. We found a statistically significant modifying effect of school connectedness on the association between sex and monthly cannabis use. For early cannabis use, we found no modifying effect of school connectedness nor any association with sex. CONCLUSIONS Measures to reduce adolescents' cannabis use could be better adapted to local context and more tailored to specific higher-risk groups. School connectedness is a protective factor for cannabis use, although this effect appears stronger for girls than boys.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Background Since 2014, the Burkina Faso government has made Seasonal Malaria Chemoprevention (SMC) a priority in its strategic plan to fight against malaria among children aged from 3 to 59 months. Very few studies have examined the care provided by community health workers in the framework of this strategy. The purpose of this study was to evaluate the level of quality of care provided by the latter. Methods This was a mixed study. The quantitative component consisted of a non-participant observation of community health workers during the administration of care. The qualitative component consisted of one-on-one interviews with community health workers, child caregivers and head nurses. Five dimensions (organizational accessibility, interpersonal relationship, technical competence, safety of care and satisfaction of child caregivers) adapted from the Donabedian quality of care model were used to assess the quality level of care. The Corlien et al. Health Systems Research Program Implementation Scale was used to establish quality scores for each of the five dimensions. The study sites were the health centers located in the administrative centers of the 4 communes of the health district of Boulsa. The data were collected during the first cycle of the 2017 SMC campaign. Results A total of 14 active pairs (28 CHWs) were observed and 40 in-depth interviews with community health workers, Head nurses in duty and community leaders were conducted. The results show that community health workers worked in pairs. They had all received SMC training and possessed equipment to do their job. The dimensions of organizational accessibility and satisfaction of the caregivers were rated as good. The dimensions of interpersonal relationship and technical competence were judged to be of an acceptable score. Safety of care was judged to be of a low-level score. The overall quality of care was considered acceptable. Conclusion The results of this study have shown that despite the difficulties faced by community health workers, they manage to deliver acceptable quality of care. Their use would be an asset for SMC in particular and for the health system in general.

Abstract
The effect of the presence of electron-phonon (e-ph) coupling in the SiC, GeC and SnC hybrids is studied in the framework of the ab initio perturbation theory. The electronic bang gap thermal dependence reveals a normal monotonic decrease in the SiC and GeC semiconductors, whereas SnC exhibits an anomalous behavior. The electron line widths were evaluated and the contributions of acoustic and optical phonon modes to the imaginary part of the self-energy were determined. It has been found that the e-ph scattering rates are globally controlled by the out-of-plane acoustic transverse mode ZA in SiC while both ZA and ZO are overriding in GeC. In SnC, the out-of-plane transverse optical mode ZO is the most dominant. The relaxation lifetime of the photo-excited electrons shows that the thermalization of the hot carrier occurs at 90 fs, 100 fs and 120 fs in SiC, GeC and SnC, respectively. The present study properly describes the subpicosecond time scale after sunlight illumination using an approach that requires no empirical data. The results make the investigated structures suitable for providing low cost and high-performance optical communication and monitoring applications using 2D materials.

Abstract
Providing evidence of potential changes in the climate has become increasingly important as it is the first step towards adopting mitigation and adaptation measures and planning for urban resilience. In this study a statistical analysis of the ambient air temperature time series over Sydney, Australia during 1970-2016 has been carried out with the aim to investigate potential changes towards higher temperatures. The dataset has been statistically analyzed using different techniques, concluding that the investigation should be performed on a monthly basis. A persistence analysis was conducted using different statistical approaches to investigate the dependence between consecutive monthly and daily ambient air temperature values. A trend analysis of the ambient air temperature and degree days time series has been conducted using linear regression to estimate the linear trend (slope) and its statistical significance (using a Student-t-test) and the Kendall-Mann test to identify the time at which the tendency starts to occur as well as the time after which it becomes statistically significant.

Abstract
Canada's history of nation building, combined with its status as a so-called middle power in international affairs, has been translated into an approach to global health that is focused on equity and global citizenship. Canada has often aspired to be a socially progressive force abroad, using alliance building and collective action to exert influence beyond that expected from a country with moderate financial and military resources. Conversely, when Canada has primarily used economic self-interest to define its global role, the country's perceived leadership in global health has diminished. Current Prime Minister Justin Trudeau's Liberal federal government has signalled a return to progressive values, driven by appreciation for diversity, equality, and Canada's responsibility to be a good global citizen. However, poor coordination of efforts, limited funding, and the unaddressed legacy of Canada's colonisation of Indigenous peoples weaken the potential for Canadians to make meaningful contributions to improvement of global health equity. Amid increased nationalism and uncertainty towards multilateral commitments by some major powers in the world, the Canadian federal government has a clear opportunity to convert its commitments to equity and global citizenship into stronger leadership on the global stage. Such leadership will require the translation of aspirational messages about health equity and inclusion into concrete action at home and internationally.

Abstract
Seasonal malaria chemoprevention (SMC) for children < 5 is a strategy that is gaining popularity in West African countries. Although its efficacy to reduce malaria incidence has been demonstrated in trials, the effects of SMC implemented in routine program conditions, outside of experimental contexts, are unknown. In 2014 and 2015, a survey was conducted in 1,311 households located in Kaya District (Burkina Faso) where SMC had been recently introduced. All children < 72 months were tested for malaria and anemia. A pre–post study with control group was designed to measure SMC impact during high transmission season. A difference-in-differences approach was coupled in the analysis with propensity score weighting to control for observable and time-invariant nonobservable confounding factors. SMC reduced the parasitemia point and period prevalence by 3.3 and 24% points, respectively; this translated into protective effects of 51% and 62%. SMC also reduced the likelihood of having moderate to severe anemia by 32%, and history of recent fever by 46%. Self-reported coverage for children at the first cycle was 83%. The SMC program was successfully added to a package of interventions already in place. To our knowledge, with prevalence < 10% during the peak of the transmission season, this is the first time that malaria can be reported as hypo-endemic in a sub-Sahelian setting in Burkina Faso. SMC has great potential, and along with other interventions, it could contribute to approaching the threshold where elimination strategies will be envisioned in Burkina Faso.

Abstract
Adrenal gland hemangioma is an extremely rare benign vascular tumor. It is frequently discovered as incidental radiological findings in abdominal imaging performed for various reasons. The preoperative diagnosis is very difficult, generally CT and MR imaging are useful for the diagnosis of hemangioma. In front of an adrenal mass discovered incidentally there are several factors to consider: the tumor size, its secreting character or not, imaging data suggestive of malignancy and complications. These factors help in determining which incidental adrenal masses should be excised.
Bakground Adrenal glands hemangiomas are rare, benign and non-functional tumors. They are often discovered as incidentalomas either during imaging or autopsies. Nearly 70 cases were reported in the literature. Case report We report a case of a non-functional adrenal hemangioma (AH) that was incidentally found on abdominal ultra sonography (US) during the routine control of diabetes of a 58 year-old man. Imaging with US and Computed tomography (CT) showed an heterogeneous and partially calcified 6 cm tumor of the right adrenal gland. The mass was surgically excised and the histological examination concluded to an adrenal haemangioma. Conclusion Although rare, AH should be included in the differential diagnosis of the adrenal neoplasmas.

Abstract
The New Zealand white (NZW) rabbit has been and is right now regularly utilized in ophthalmic surgery evaluation. Inside NZW rabbit eye, the visibility of ocular structures throughout surgical procedure is fantastic. Younger rabbits are used in different ages for the evaluation of ophthalmic surgery. Complete studies of ocular development in the NZW rabbits have not been reported previously. The aim of the present investigation was to describe the major landmarks and the time course of the pre- and post-natal development of the complete eye tunics of the NZW rabbit to give a superb model as well as a fruitful area for further ophthalmological investigations. Serial histological sections of NZW rabbit prenatal (E13-E28) and post-natal (P1-P14) stages were examined, respectively. The eye of the NZW rabbit developed in a similar manner to that of the human and domestic animals eyes; the principal differences were at the time of occurrence of certain developmental events, absence of pigmentation which represent an exploited benefit for ophthalmic surgery, remarkable Bowman's membrane at E25, poor developed ciliary stroma and juvenile retinal layer until P9. In human, the basic morphogenetic processes of the development of eye tunics are completed towards the end of the first half of gestation period. However, the latter represents the beginning stage of the development of eye tunics in the rabbit. Thus, allowing various extensive ophthalmic researches to be performed.

Abstract
With solid evidence that free healthcare increases the utilization of health services, Burkina Faso recently exempted all children under five and pregnant women from direct payment at health facilities. However, there is little insight into the capacity to maintain the gains attributable to free healthcare under routine conditions of implementation at the national scale. In particular, the repercussions of its interruption are unknown. The objective is to assess the effects of a sequence of natural interventions including the introduction, interruption and reintroduction of free healthcare on health-seeking practices and utilization of healthcare facilities by children under five. This is an embedded mixed methods study conducted in Kaya district, Burkina Faso. The quantitative component is based on a reversal longitudinal design. Pooled interrupted time-series analysis was performed to assess changes in the monthly number of visits from January 2005 to March 2015. Qualitative data were collected through in-depth interviews with health personnel and mothers to better understand the quantitative results. The results show that visits to health centres dropped immediately and significantly when free healthcare was interrupted (-146, CI95% [-255; -37]). They increased again when free healthcare was reintroduced (+89, CI95% [-11; 187]). Both urban and rural centres were affected. Self-medication and visits to traditional healers were reported more frequently during the withdrawal of free healthcare, and tensions between the population and health personnel increased. Implementation problems other than insufficient funding limited the coverage or intensity of free healthcare. While removing user fees could potentially improve mothers and children's health in Burkina Faso, this study shows that demand for healthcare remains highly sensitive to price changes. Gains in utilization attributable to free healthcare may vanish rapidly if user fees are reintroduced. It is essential to support an effective and sustainable implementation of this ambitious initiative.

Abstract
OBJECTIVE To identify the factors associated with home births in the Kaya health district in Burkina Faso, where child delivery was free of charge between 2007 and 2011. METHODS Both qualitative and quantitative data were collected from the Kaya Health and Demographic Surveillance System (Kaya HDSS) among women who delivered at home or in a health facility between January 2008 and December 2010. Multilevel logistic regression was applied to quantitative data, while the qualitative data were analyzed thematically based on emerging themes, subthemes, and patterns across group and individual cases. RESULTS The findings indicate that 12% (n=311) of childbirths occurred at home (n=2560). Key factors associated with home birth were age, distance from the household to the primary health center, and prenatal visits. The qualitative analysis showed that immediate child delivery, previous experience of giving birth at home, negative experiences with health centers, fear of cesarean delivery, and lack of transport are key predictors of home births. CONCLUSION Though relevant, addressing the financial barrier to health care is not enough. Additional measures are necessary to further reduce the rate of home births.

Abstract
Abstract
Background:
Neoadjuvant chemotherapy (NACT) is generally established as a therapeutic option for selected high-risk patients with localized breast cancer, including triple negative breast cancer (TNBC). On a patient level, achievement of pathologic complete response (pCR) at the time of surgery is associated with improved long-term outcomes and is considered to be a surrogate marker. Response to NACT is a complex phenomenon dependent on both host and tumor characteristics. While tumor characteristics, such as receptors and tumor grade, have been well studied as predictors of pCR, host characteristics to predict pCR have been less well studied. Background parenchymal enhancement (BPE) is an imaging characteristic that reflects the normal enhancement of the fibroglandular tissue on breast MRI, and could potentially modulate response to NACT by influencing the tumor microenvironment and vasculature. The aim of this study was to explore the ability of baseline BPE to predict pCR in a cohort of young women with localized breast cancer.
Methods:
A retrospective chart review was conducted of women ages 40 and under with stage II-III breast cancer treated with NACT at our institution from 2004 – 2014. Demographic, clinical, and pathological variables were extracted from the medical records. The primary outcome was achievement of pCR, defined as ypT0/is ypN0, after NACT. BPE pattern in the contralateral breast was obtained from pre-treatment breast MRI reports if available and otherwise was retrospectively determined by a breast radiologist blinded to patient outcomes. BPE was dichotomized as low (minimum and mild) vs. high (moderate and marked). Logistic regression was used for statistical analysis.
Results:
A total of 69 patients ages 40 and under received NACT for localized breast cancer during the study period and had available pre-treatment breast MRI images. Median age at diagnosis was 36 (range 27-40). The majority of patients had grade 3 (65.2%), ER+/HER2- (60.9%) tumors while 24.6% had TNBC. Among pre-treatment breast MRIs, 42 (60.9%) patients had minimum or mild BPE and 27 (39.1%) patients had moderate or marked BPE. The overall pCR rate was 39%. After controlling for tumor grade, ER status, HER2 status, clinical stage, and type of NACT, high baseline BPE was associated with a trend towards higher odds of achieving pCR compared to low BPE (OR = 1.49, 95% CI 0.47–4.71), though statistical significance was not reached (p = 0.50). When stratified by ER status, the relationship was stronger among the ER+ subset (OR 1.8, p = 0.49) compared to the ER- subset (OR 1.3, p = 0.78).
Conclusions:
A statistically significant association between high baseline BPE and achievement of pCR was not found in this limited sample size, but a trend towards higher pCR rates, particularly with ER+ tumors, was seen. While tumor factors have traditionally been used to predict pCR, BPE is a readily available MRI imaging characteristic that reflects the tumor microenvironment and may be useful in building a model that incorporates tumor factors along with host factors to develop personalized NACT regimens for young women with breast cancer.

Abstract
Identifying mechanisms through which individual differences in reward learning emerge offers an opportunity to understand both a fundamental form of adaptive responding as well as etiological pathways through which aberrant reward learning may contribute to maladaptive behaviors and psychopathology. One candidate mechanism through which individual differences in reward learning may emerge is variability in dopaminergic reinforcement signaling. A common functional polymorphism within the catechol-O-methyl transferase gene (COMT; rs4680, Val(158) Met) has been linked to reward learning, where homozygosity for the Met allele (linked to heightened prefrontal dopamine function and decreased dopamine synthesis in the midbrain) has been associated with relatively increased reward learning. Here, we used a probabilistic reward learning task to asses response bias, a behavioral form of reward learning, across three separate samples that were combined for analyses (age: 21.80 ± 3.95; n = 392; 268 female; European-American: n = 208). We replicate prior reports that COMT rs4680 Met allele homozygosity is associated with increased reward learning in European-American participants (β = 0.20, t = 2.75, P < 0.01; ΔR(2) = 0.04). Moreover, a meta-analysis of 4 studies, including the current one, confirmed the association between COMT rs4680 genotype and reward learning (95% CI -0.11 to -0.03; z = 3.2; P < 0.01). These results suggest that variability in dopamine signaling associated with COMT rs4680 influences individual differences in reward which may potentially contribute to psychopathology characterized by reward dysfunction.

Abstract
BACKGROUND One of the major challenges to total knee arthroplasty (TKA) is optimal pain control. Effective analgesia is capital in fast-track surgery programs to allow patient's early functional outcomes. OBJECTIVES Compare length of stay (LOS) short-term pain control, and patients' satisfaction at 1 month between local infiltration analgesia (LIA) combined with femoral nerve block (FNB) and FNB only in patients undergoing TKA. PATIENTS AND METHODS Two hundred and fifty-four patients were included in a randomized prospective study and distributed in two groups. The first group received an intraoperative LIA (150 mL mixture of ropivacaine 2.0 mg/mL + ketorolac 30 mg + adrenaline 10 μg/mL) combined to an FNB. The control group had only an FNB. Demographical data and visual analog scale (VAS) score were obtained preoperatively, at 36 h after surgery and at the 15-day follow-up. Patients' satisfaction at 1 month was also evaluated. Statistical analysis data was performed. RESULTS No differences in demographical data and preoperative VAS score were observed between both groups. LIA group had a lower VAS score at 36 h after surgery (1.34 ± 1.31 vs. 3.68 ± 1.932 in the control group, p = 0.00), but these differences were not maintained at the 15-day follow-up (4.51 ± 1.889 vs. 4.11 ± 1.940 in the control group, p > 0.05). LOS and patients' satisfaction were comparable between groups. Patients with LIA had no additional complications. CONCLUSIONS LIA is a safe adjuvant to FNB to reduce perioperative pain during the first 36 h after TKA. Its effects wean with time, but do cover the first crucial hours of rehabilitation in a fast-track program. LIA seems don't modify postoperative course nor patient's satisfaction at short-term follow-up. The final impact of LIA on surgical outcome is still to be determined.
