Wildland fire, air pollution and cardiovascular health: is it time to focus on the microvasculature as a risk assessment tool?

Climate change favors weather conditions conducive to wildland fires. The intensity and frequency of forest fires are increasing, and fire seasons are lengthening. Exposure of human populations to smoke emitted by these fires increases, thereby contributing to airborne pollution through the emission of gas and particulate matter (PM). The adverse health outcomes associated with wildland fire exposure represent an important burden on the economies and health systems of societies. Even though cardiovascular diseases (CVDs) are the main of cause of the global burden of diseases attributable to PM exposure, it remains difficult to show reliable associations between exposure to wildland fire smoke and cardiovascular disease risk in population-based studies. Optimal health requires a resilient and adaptable network of small blood vessels, namely, the microvasculature. Often alterations of this microvasculature precede the occurrence of adverse health outcomes, including CVD. Biomarkers of microvascular health could then represent possible markers for the early detection of poor cardiovascular outcomes. This review aims to synthesize the current literature to gauge whether assessing the microvasculature can better estimate the cardiovascular impact of wildland fires.

Sleep Medicine Knowledge Among Graduating Medical Students in Lebanon During an Economic and Political Crisis: A Preliminary Survey.

Objectives Sleep disorders are prevalent and underrecognized during both economic and political crises. They are a major reason for poor overall health and decreased quality of life. Sleep medicine education is limited at most medical schools, resulting in limited awareness of this important aspect of healthcare. The aim of the study is to assess sleep medicine knowledge of graduating medical students in Lebanon and to assess their readiness to tackle sleep health issues in a country during an unprecedented crisis. Methods Final-year medical students at 7 medical schools in Lebanon were invited to fill a survey between January 2020 and March 2021. The Assessment of Sleep Knowledge in Medical Education survey was used to assess their knowledge in sleep medicine. The curriculum organizers at the medical schools were also surveyed. Student's t -test was used for analysis. Results 158 and 58 students completed the survey during 2020 and 2021, with a mean overall score on sleep knowledge of was 17.5 and 15.9 /30, respectively. There was no difference in mean knowledge scores by gender, age, American versus European medical school systems, and between medical schools that included sleep medicine in their curriculum versus those that did not. Conclusions Presence of sleep medicine education in the curriculum was associated with higher scores on ASKME among graduating Lebanese medical students. Given the low response rate, however, this descriptive pilot data could be used as a launching pad for a larger study, with a more representative sample, for generalizable results.

Epidemiology and management of hypertension among refugees in the Middle East: a review of the literature.

This review aims to explore the burden of hypertension among refugees in the Middle East by reporting its prevalence, risk factors and access to care. A comprehensive literature search was performed using Web of Science, Ovid MEDLINE, PubMed, SCOPUS, CINHAL+, WHO Regional Office for the Eastern Mediterranean (EMRO) and United Nations High Commissioner for Refugees (UNHCR) on articles spanning from 1948 until 2020. Most studies were cross-sectional in design. After applying eligibility criteria 17 articles and 4 reports were included. Findings showed that hypertension represents a major burden among refugees. Hypertension risk factors present among the refugee population included increased salt intake, physical inactivity, and smoking. The majority of hypertensive refugees sought care for their condition at the public health care services. Barriers to seeking care included high cost of healthcare, accessibility to provided services, and lack of knowledge for the need to seek care. Non-adherence to medication among refugees was primarily linked to cost and lack of symptoms. This review highlights the need for further studies to shed light on the importance of targeting hypertension among refugees, to lower morbidity and mortality, in addition to providing adequate healthcare services to this population.

Prevalence and Factors Associated with Visiting the Dentist Only for Emergency Care Among Indigenous People in Ontario.

Ontario has the largest Indigenous population in Canada. This study aims to examine the prevalence and factors associated with poor dental care use amongst the Indigenous in Ontario. Data from the 2014 cycle of the Canadian Community Health Survey was used. The main outcome was defined as visiting the dentist only for emergency care. Stepwise multivariable logistic regression was performed to assess the association between socio-demographic, socio-economic, and the health related factors and emergency dental care use. 28% of the participants reported visiting the dentist only for emergencies. First Nations people were at increased odds of having poor dental care (OR 2.01, CI 1.12-3.95). Additionally, being male, a smoker, having fair/poor health and lacking dental insurance puts the Indigenous Ontarians at increased odds of having the outcome. Improvements to the current social benefit programs could help better cater to the needs of this population.

Dental care use by immigrant Canadians in Ontario: a cross-sectional analysis of the 2014 Canadian Community Health Survey (CCHS).

BACKGROUND: Ontario is home to the largest number of immigrants in Canada. However, very little is known about their dental care utilization patterns. The purpose of this study is to determine the prevalence of poor dental health care use among the immigrant population of Ontario and how various socio-demographic, socio-economic and health-related factors are associated with it. METHODS: Analysis was performed on a total of 4208 Ontarian immigrants who participated in the dental care module of the 2014 cycle of the Canadian Community Health Survey. Poor dental care use was defined by the two variables: not visiting the dentist in the past year and/or visiting the dentist only for emergency purposes. Multivariable logistic regression was performed to assess the associations between the two outcomes and the socio-demographic, socio-economic and health-related factors. RESULTS: Thirty three percent of immigrants reported not visiting the dentist in the past year and 25% reported visiting only for emergencies. The leading components associated with poor dental care utilization were being a new immigrant, of male gender, having low educational attainment, low household income and lacking dental insurance. CONCLUSIONS: This study is the first to highlight oral health care use patterns amongst immigrants in Ontario. Given that a large proportion of the immigrant population in Ontario have poor dental care use, education and outreach programs informing incoming immigrants of preventative dental care may improve overall dental health.

Urbanization and Socioeconomic Disparities in Hypertension among Older Adult Women in Sudan.

BACKGROUND: Evidence from the developed world associates higher prevalence of hypertension with lower socioeconomic status (SES). However, patterns of association are not as clear in Africa and other developing countries, with varying levels of socioeconomic development and epidemiological transition. Using wealth and education as indicators, we investigated association between SES and hypertension among older adult women in Sudan and examined whether urbanicity mediates the relationship. METHODS: The sample included women aged 50 years and over participating in the nationally representative population-based second Sudan Health Household Survey (SHHS) conducted in 2010. Principal components analysis was used to assign each household with a wealth score based on assets owned. The score was categorized into quintiles from lowest (poorest) to highest (richest). FINDINGS: The sample included a total of 5218 women, median and mean age 55 and 59 years, respectively, with the majority not have any schooling (81.6%). The overall prevalence of reported hypertension was found to be 10.5%. After adjustment for age, marital status, work status and urban/rural location, better wealth and higher education were independently and positively associated with hypertension prevalence rates. However, when stratified by urbanicity, the relationship between wealth and hypertension lost its significance for women in urban areas but maintained it in rural areas, increasing significantly and consistently with each increase in quintile index (adjusted odds ratio, aOR1 = 1.95 95% CI = 1.08-3.52; aOR2 = 5.25, 95% CI = 3.01-9.15; aOR3 = 8.27, 95% CI = 4.78-14.3; and aOR4 = and 11.4, 95% CI = 6.45-20.0; respectively). By contrast, education played a greater role in increasing the odds of hypertension among women in urban locations but not in rural locations (aOR = 2.14, 95% CI = 1.25-7.90 vs. aOR = 0.79, 95% CI = 0.27-2.30, respectively). CONCLUSIONS: Our findings of a socioeconomic gradient in the prevalence of hypertension among women, mediated by urbanization, call for targeted interventions from early stages of economic development in Sudan and similar settings of transitioning countries.

Factors associated with shorter night-time sleep in toddlers: The Survey of Young Canadians.

OBJECTIVES: Adequate sleep in childhood is important for healthy development. No information exists on the predictors of night-time sleep among toddlers in Canada. The aim of this study was to determine the prevalence of and to identify factors associated with sleeping <11 consecutive hours per night among children aged 1-2 years in Canada. METHODS: Data from the cross sectional Survey of Young Canadians (SYC) 2010 were used. The biological mother reported on toddlers' sleep duration at night. Based on cut-off values used in previous studies, shorter night-time sleep was defined as sleeping <11 hours per night. Multivariable logistic regression was conducted to identify the associations between socio-demographic, maternal, sleep and child-related variables with shorter sleep at night. RESULTS: Analysis of 3675 toddlers revealed that 57% slept <11 hours per night. Results of the regression analysis showed that being from an immigrantfamily was significantly associated with shorter night-time sleep. Being from a higher income household, having a mother aged between 25 and 34 years at the time of the survey, and napping ≥2 hours during the day were significantly related to sleeping ≥11 hours per night. Other socio-demographic, maternal and child-related variables were not associated with night-time sleep. CONCLUSION: This was the first population-based, nationally representative study to examine factors related to shorter night-time sleep in Canadian toddlers. Socio-demographic factors and nap duration were associated with night-time sleep duration. More adequate early childhood sleep hygiene awareness efforts are recommended, especially in vulnerable populations.

Dental care use in Ontario: the Canadian community health survey (CCHS).

BACKGROUND: Oral health is a significant measure of overall health, and regular dental visits are recommended for the maintenance of oral health. The purpose of this study is to determine the pattern (amount and type) of, and factors associated with dental care use among Ontarians. METHODS: Data from the 2014 cycle of the Canadian Community Health Survey was used and analysis was restricted to individuals aged 12 and above residing in Ontario. Dental care use was defined by two distinct outcomes: not visiting a dentist within the past year and visiting a dentist only for emergencies. Multivariable logistic regression was performed to examine the association between socio-demographic, health behavior, oral health, and other health-related factors and the two outcomes. RESULTS: More than a quarter of participants reported not visiting the dentist in the last year, and 19% reported usually visiting a dentist only for emergencies. Multivariable logistic regression analysis suggested that males, individuals of Aboriginal status, those with low educational attainment, low household income, no dental insurance, who smoked, less frequent teeth brushing, poor health of teeth and mouth, or had diabetes were at a significant increased likelihood of not visiting the dentist within the past year, and only visiting a dentist for emergency care. CONCLUSIONS: Socioeconomic status, self-reported oral health, and general health behaviors were associated with dental care use. These findings highlight the need for focusing efforts toward improving dental care use among Ontarians.

Landscape of Research on Older Adults' Health in the Arab Region: Is It Demography-Driven or Development-Dependent?

OBJECTIVES: To describe the quantity, methods, themes, and collaboration profiles of research on older adults' health in the Arab world, and map research productivity against demographic, economic, and development indicators. METHODS: A scoping review of research on older adults' health drawing from 7 databases and covering the period 1994-2013. RESULTS: Aging research output has increased 6-fold over the study period, with middle-income countries showing the sharpest rise. The majority of the reviewed publications are descriptive in nature, oriented toward examining the extent of disease or factors associated with various morbidity and mortality outcomes (88.5%). Despite the increasing regional instability, there is a dearth of studies on "seniors in emergencies." Collaboration with international coauthors (16.0%) has been more frequent than with regional coauthors (4.2%). Correlation analysis suggests that research production has been more strongly influenced by literacy rates than by population aging indicators, Gross Domestic Product, or government investment in research and development. DISCUSSION: This study lays the basis for a "roadmap" for research on older adults' health in the Arab region. It calls for cooperation among various stakeholders to produce a targeted and well-informed research agenda that is more responsive to emerging and context-specific needs of older adults in the region.

Factors associated with difficulty accessing health care for infants in Canada: mothers' reports from the cross-sectional Maternity Experiences Survey.

BACKGROUND: Approximately 13% of Canadian mothers report difficulty accessing health care for their infants, yet little is known about the factors associated with difficulty. Therefore, we examined factors associated with difficulty accessing non-routine health care for Canadian infants, from birth to 14 months of age, as reported by their mothers. METHODS: Data was drawn from the Maternity Experiences Survey (MES), a cross-sectional, nationally representative survey of mothers who gave birth between November 2005 and May 2006, aged 15 years or older, and lived with their infants at the time of survey administration. A multivariable logistic regression analysis was conducted to determine factors associated with reporting difficulty, with difficulty defined as a mother reporting it being somewhat or very difficult to access a health care provider. RESULTS: Analysis of 2832 mothers who reported needing to access a health care provider for their infant for a non-routine visit found that 13% reported difficulty accessing a provider. Factors associated with reporting difficulty were: residing in Quebec (aOR 1.89, 95% CI: 1.31-2.73), being an immigrant (aOR 1.58, 95% CI: 1.10-2.27), mistimed pregnancy (aOR 1.44, 95% CI: 1.05-1.98), low level of social support (aOR 1.69, 95% CI: 1.05-2.73), good health (aOR 1.88, 95% CI: 1.43-2.47), postpartum depression symptoms (aOR 1.55, 95% CI: 1.02-2.37) and a self-reported 'too-short' postpartum hospital stay (aOR 1.69, 95% CI: 1.21-2.35). Additionally, accessing care for an infant with a birth weight of 2500 g or more (aOR 2.43, 95% CI: 1.02-5.82), was associated with reporting difficulty. Household income, mothers' level of education, marital status, Aboriginal ethnicity, and size of community of residence were not associated with difficulty accessing care. CONCLUSIONS: Ease of health care access for Canadian infants is not equal, suggesting that efforts to improve access should be tailored to groups facing increased difficulties.

Prevalence, correlates and management of type 2 diabetes mellitus in Lebanon: findings from a national population-based study.

AIMS: This study aims to examine the prevalence, associated risk factors and complications of diabetes, as well management and preventive care in Lebanon, a small, middle-income country of the Mediterranean region. METHODS: Using a comprehensive multi-dimensional questionnaire, a cross-sectional national survey of 2195 Lebanese adults aged ≥25 years was conducted based on the WHO STEPwise guidelines. The outcome variable, diabetes, was self-reported. Measures for diabetes management included frequency of blood glucose testing and regular eye and foot exams. Macrovascular and microvascular complications were also recorded. RESULTS: The prevalence of type 2 diabetes was 8.5% (95%CI=7.3-9.7). Factors associated with an increased risk of having diabetes were: being divorced or widowed (OR=2.56; 95%CI=1.07-5.42) compared to single, being obese (OR=1.50, 95%CI=1.00-2.57), and having a family history of diabetes (OR=3.40;95%CI=2.48-5.19). Vigorous physical activity significantly decreased the odds of diabetes (OR=0.42; 95%CI=0.24-0.72). Diabetes management and self-care goals were as follows: 82% were not measuring their blood sugar via dextro on a daily basis, 64.2% did not have a foot exam within the past year, and 52.4% did not obtain the recommended yearly eye exam. The most common complications included heart disease (27.8%) and retinopathy (16.6%). CONCLUSIONS: Prevalence of diabetes in Lebanon was comparable to that found in the West, yet remained lower than estimates in other resource-rich neighboring countries. Adherence to management and self-care measures was sub-optimal resulting in high complication rates. Contextual factors play a role in increasing diabetes risk. Population-based interventions to enhance and promote self-management behaviors are essential to improve complication rates.
