Abstract Recent studies have identified inequality in the distribution of air pollution attributable health impacts, but to our knowledge this has not been examined in Canadian cities. We evaluated the extent and sources of inequality in air pollution attributable mortality at the census tract (CT) level in seven of Canada's largest cities. We first regressed fine particulate matter (PM2.5) and nitrogen dioxide (NO2) attributable mortality against the neighborhood (CT) level prevalence of age 65 and older, low income, low educational attainment, and identification as an Indigenous (First Nations, Métis, Inuit) or Black person, accounting for spatial autocorrelation. We next examined the distribution of baseline mortality rates, PM2.5 and NO2 concentrations, and attributable mortality by neighborhood (CT) level prevalence of these characteristics, calculating the concentration index, Atkinson index, and Gini coefficient. Finally, we conducted a counterfactual analysis of the impact of reducing baseline mortality rates and air pollution concentrations on inequality in air pollution attributable mortality. Regression results indicated that CTs with a higher prevalence of low income and Indigenous identity had significantly higher air pollution attributable mortality. Concentration index, Atkinson index, and Gini coefficient values revealed different degrees of inequality among the cities. Counterfactual analysis indicated that inequality in air pollution attributable mortality tended to be driven more by baseline mortality inequalities than exposure inequalities. Reducing inequality in air pollution attributable mortality requires reducing disparities in both baseline mortality and air pollution exposure.

ABSTRACTBackground Standard methods assessing pain in rodents are often observer dependent, potentially resulting in biased outcomes. Advanced dynamic weight bearing (ADWB) offers an observer-independent approach that can provide objective, reliable data in preclinical pain research.Aims The aim of this study was to characterize the use of ADWB in assessing murine responses to allyl isothiocyanate (AITC)-induced hyperacute hypersensitivity and identify best practices for use of the device.Methods Male C57BL/6J mice received intraplantar injections of saline or 0.1% AITC solution and were assessed using the ADWB system; simultaneous observer-dependent durations of paw licking and biting were measured. ADWB data were analyzed using the proprietary software from Bioseb and correlated to observer-dependent results, with parameters assessed to optimize data collected.Results ADWB detected pain-directed changes in weight and surface area distribution in AITC-treated mice, with paw weight and surface area placement correlating to paw licking and biting. Optimization of adjustable threshold parameters allowed for reduced coefficients of variability and increased duration of validated data.Conclusions The ADWB assay provides an efficient and unbiased measure of chemical-induced hyperacute hypersensitivity in mice. ADWB detection parameters influence amount of validated data and variability, a consideration for data analysis in future studies.

- Abstract
Background: Healthcare workers are at high risk of developing occupational hand dermatitis (HD) due to their frequent exposure to wet‐work and use of gloves. Complaints of HD may interfere with work and cause loss of work productivity, or sick leave, and may have impact on job pleasure and performing daily activities. The prevalence of HD among intensive care unit (ICU) nurses is unknown. Objectives: To investigate the point prevalence and the 1‐year prevalence of HD among ICU nurses, and to determine the impact of HD on work and daily activities. Method: A questionnaire‐based cross‐sectional study was performed among ICU nurses. Participants were recruited in the Amsterdam University Medical Centre. A symptom‐based questionnaire was used to determine HD and atopic predisposition, and an additional questionnaire was used concerning the influence of HD. ICU nurses with an atopic predisposition or symptoms suiting HD were invited for the hand dermatitis consultation hour (HDCH). Data were analysed with logistic regression. Results: A total of 184 ICU nurses were included. The point prevalence of HD was 9.8% (95% CI: 5.9–15.0) and the 1‐year prevalence was 26.6% (95% CI: 20.4–33.6). Sick leave was reported by 0.5%. HD seemed to have more impact on job pleasure than on work productivity. Conclusion: The high prevalence rate of HD resulting from our study highlights the need for the prevention of occupational HD among healthcare workers. [ABSTRACT FROM AUTHOR]

BackgroundUltra-marathon running participation has become increasingly more popular in recent years; however, there is inconclusive evidence concerning the effects of participation on cognition and cardiovascular function. The purpose of this study was to examine alterations in cardiovascular function and cognitive performance and their association in ultra-marathon runners prior to and following an ultra-endurance event.MethodsIn total, 24 runners (19 males and 5 females) participated in an ultra-marathon race (FatDog120) held in British Columbia, Canada. Participants competed in varying races distances [48 km (n = 2), 80 km (n = 7), 113 km (n = 3), and 193 km (n = 12)]. Cognition was assessed prior to and upon race completion using simple reaction time, choice reaction time, discrimination reaction time, and recognition memory (% correct). Cardiovascular function was assessed prior to and upon race completion using radial applanation tonometry for diastolic pulse contour examination.ResultsCognitive performance displayed significantly (p < 0.001) slower reaction times post-race for simple (30.2%), discrimination (22.7%), and choice reaction time (30.5%), as well as a significant (p < 0.05) reduction in memory test performance (−8.2%). A significant association between systemic vascular resistance and choice reaction time was observed post-race (r = 0.41, p < 0.05). Significant changes in post-race cardiovascular function were observed in resting heart rate (31.5%), cardiac output (27.5%), mean arterial blood pressure (−5.6%), total systemic resistance (−17.6%), systolic blood pressure (−7.0%), pulse pressure (−11.2%), and rate pressure product (22.4%). There was evidence of enhanced cardiovascular function being associated with improved cognitive performance before and after the ultra-endurance event.ConclusionUltra endurance running is associated with marked impairments in cognitive performance that are associated (at least in part) with changes in cardiovascular function in healthy adults.

Indigenous peoples have thrived since time immemorial across North America; however, over the past three to four generations there has been a marked increase in health disparities amongst Indigenous peoples versus the general population. Heart disease and mental health issues have been well documented and appear to be interrelated within Indigenous peoples across Canada. However, Western medicine has yet to clearly identify the reasons for the increased prevalence of heart disease and mental health issues and their relationship. In this narrative review, we discuss how Indigenous perspectives of health and wholistic wellness may provide greater insight into the connection between heart disease and mental wellbeing within Indigenous peoples and communities across Canada. We argue that colonization (and its institutions, such as the Indian Residential School system) and a failure to include or acknowledge traditional Indigenous health and wellness practices and beliefs within Western medicine have accelerated these health disparities within Indigenous peoples. We summarize some of the many Indigenous cultural perspectives and wholistic approaches to heart health and mental wellbeing. Lastly, we provide recommendations that support and wholistic perspective and Indigenous peoples on their journey of heart health and mental wellbeing.

FOS: Economics and business ,negotiation concession ,manipulation - Abstract
Reaching agreement in distributive negotiations often requires making concessions, in which one side incurs a cost to provide a benefit to the other party. Although these two aspects, conceder-cost and receiver-benefit, coexist in any concession, past work has not disentangled the potentially differential effects of concessions framed as conceder-cost versus receiver benefit on negotiation processes and outcomes. In this paper, we document that concession-givers use conceder-cost frames more frequently and expect them to be more believable than receiver-benefit frames. However, receivers of concessions that emphasize conceder-cost are more skeptical of this frame and perceive their counterpart to be more manipulative than receivers of concessions that emphasize benefit. These negative perceptions, in turn lead them to make lower counteroffers compared to receivers of concessions that emphasize benefit, which ultimately help their economic outcomes.

Community-based and Indigenous-led health and wellness approaches have been widely advocated for Indigenous peoples. However, remarkably few Indigenous designed and led interventions exist within the field. The purpose of this study was to evaluate an Indigenous-led and community-based health and wellness intervention in a remote and rural Indigenous community. This protocol was designed by and for Indigenous peoples based on the aspirations of the community (established through sharing circles). A total of 15 participants completed a 13-week walking and healthy lifestyle counselling program (incorporating motivational interviewing) to enhance cardiometabolic health. Measures of moderate-to-vigorous physical activity (MVPA; 7-day accelerometry and self-report), predicted maximal aerobic power (VO2max; 6-min walk test), resting heart rate and blood pressure, and other health-related physical fitness measures (musculoskeletal fitness and body composition) were taken before and after the intervention. The intervention led to significant (p < 0.05) improvements in VO2max (7.1 ± 6.3 % change), with the greatest improvements observed among individuals with lower baseline VO2max (p < 0.05, r = -0.76). Resting heart rate, resting systolic blood pressure, and resting diastolic blood pressure decreased significantly (p < 0.05) after the intervention. Self-reported and accelerometry-measured frequency of MVPA increased significantly (p < 0.05), and the total MVPA minutes (~275 min/week) were above international recommendations. Change in VO2max was significantly correlated with change in self-reported (r = 0.42) and accelerometry-measured (r = 0.24) MVPA minutes. No significant changes were observed in weight, body mass index, waist circumference, body fat (via bioelectrical impedance), grip strength, and flexibility. These findings demonstrate that a culturally relevant and safe, community-based, Indigenous-led, health and wellness intervention can lead to significant and clinically relevant improvements in cardiometabolic health and physical activity behaviour, with the greatest changes being observed in the least active/fit individuals.

- Abstract
Background: The health benefits of routine physical activity and exercise are clear; however, increased physical activity can lead to elevated exposure to air pollution that increases the risks for adverse events. Within most Indigenous or rural communities in Canada there is limited monitoring of air quality so community members may unknowingly be at an increased health risk for adverse events while being active. Policy Components: An air quality monitor was placed outdoors in Lytton, BC, a rural First Nations community, from April 2019 ��� June 2021 and particular matter (PM1.0, PM2.5, PM10.0), inorganic matter (CO2, O3), temperature, pressure, and humidity were recorded during the two-year span. Evaluation: There were significant increases in particular matter (PM1.0, PM10.0) over the two-year sample period (p��� 0.05). There were significant relationships between the different particular matter sizes (i.e., PM1.0/2.5 (0.976), PM2.5/10.0 (0.999), and PM1.0/10.0 (0.965), respectively (p, The Health & Fitness Journal of Canada, Vol. 14 No. 3 (2021): Proceedings from the 8th International Society for Physical Activity and Health Congress

Motor disability in multiple sclerosis is often modeled using experimental autoimmune encephalomyelitis (EAE) and assessed using the clinical score (CS), an observer-dependent tool that can lead to potential bias. The Advanced Dynamic Weight Bearing (ADWB) system was evaluated as an observer-independent measurement of EAE symptoms. ADWB detected weight shifts onto the front paws as mice develop hindlimb motor disability. CS and ADWB were strongly correlated, indicated that these measures are comparable and suggesting that ADWB may be an appropriate observer-independent tool for the assessment of EAE progression.

Contains fulltext : 95844.pdf (Publisher’s version ) (Closed access) BACKGROUND: Vincristine is one of the cornerstones of the treatment of children with acute lymphoblastic leukaemia (ALL). Constipation, and peripheral and central neurotoxicities are the most common side effects. A comparative study exploring vincristine toxicity in individual patients receiving vincristine with and without azoles, however, is lacking. METHODS: In total, 20 paediatric patients with de novo ALL were included. In each patient, vincristine toxicity in the period with and without azole co-medication was retrospectively graded according to the US National Cancer Institute toxicity scale. Statistical analysis was performed using the Wilcoxon signed rank test and McNemar's test. RESULTS: Patients receiving vincristine in combination with azole treatment experienced significantly more constipation and peripheral neurotoxicity (P = 0.001 and P < 0.001, respectively). Vincristine-induced CNS toxicity was only seen in patients (30%) receiving vincristine in combination with azole treatment. CONCLUSIONS: Vincristine toxicity is significantly enhanced when combined with azole treatment and can even be life threatening. Therefore, we advise avoidance of the combination of azole and vincristine treatments in patients with ALL.

The objective of this study was to compare the fattening performance in Brahman grade cattle (crossbred cattle) and crossbred water buffalo at the same young age and fed with high roughage based fattening rations in the Philippines. Ten crossbred cattle and 10 crossbred water buffalo, aged between 18 and 24 months old were used in this experiment. The animals were fed diets consisting of 85% Napier or Para grass and 15% concentrate mixture (CM) on a dry matter (DM) basis. The grass, total DM intake and bodyweight gain were significantly ( P < 0.01) higher for the crossbred water buffalo than for the cattle. There was no species significant difference in the digestion coefficient and feed conversion rate between the crossbred cattle and water buffalo. The return over feed cost for fattening was significantly ( P < 0.05) higher in the crossbred water buffalo than in the cattle. These results clearly indicate that under high roughage-based fattening rations, young crossbred water buffalo are better able to utilize the roughage and they perform better in terms of feed intake and live weight gains than the crossbred cattle in the Philippines.

While there are many advocates of testicular cancer (TC) education, little is known about the adolescent male's attitude towards TC, knowledge of TC, or whether he is receiving this education in the physician's office. As a first phase in a three year project on TC education in the public school system, 1200 grade 10 males, mean age 16.7, 63% white 34% black, were given an 85 item validated pretest questionnaire. While 22% had heard of TC, none knew how to correctly perform Testicular Self-Examination (TSE). Analysis of the attitude questions measured on a 7 point scale (7=strongly agree) showed that adolescents are afraid of getting TC (X=5.62), are unsure about whether it could happen to them (X=3.81) or whether it could be self-diagnosed (X=3.39), but did feel that recovery is more likely with early diagnosis (X=5.38). Black adolescents were less knowledgable about and more afraid of getting TC (p

- Abstract
The pyrochlore iridates, A
2 Ir2 O7 , show a wide variety of structural, electronic, and magnetic properties controlled by the interplay of different exchange interactions, which can be tuned by external pressure. In this work, we report pressure-induced iso-structural phase transitions at ambient temperature using synchrotron-based x-ray diffraction (up to ∼20 GPa) and Raman-scattering measurements (up to ∼25 GPa) of the pyrochlore series (Sm_{1-x}Bix )2 Ir2 O7 ( x = 0, 0.02, and 0.10). Our Raman and x-ray data suggest an iso-structural transition in Sm2 Ir2 O7 atPc∼ 11.2 GPa, associated with the rearrangement of IrO6 octahedra in the pyrochlore lattice. The transition pressure decreases to ∼10.2 and 9 GPa for x = 0.02 and 0.10, respectively. For all the samples, the linewidth of three phonons associated with Ir-O-Ir (A1gand Eg ) and Ir-O (T2g4) vibrations show anomalous decrease up toPc, due to decrease in electron-phonon interaction., (© 2024 IOP Publishing Ltd.)- Published
