“…However, current research still lacks an understanding of the extent of the impact of temperature. Moreover, we performed a subgroup analysis according to age and found that people aged 21–40 were more sensitive to warm and cold effects than other age groups, which was consistent with the research results of Kale et al ( 32 ) and Wang et al ( 33 ). It was possible that people in this age group belonged to the productive age group with more outdoor exposure, and they were more likely to engage in some heavy physical work in their daily lives, which made them more prone to dehydration ( 32 ).…”

BackgroundAmbient temperature change is a risk factor for urolithiasis that cannot be ignored. The association between temperature and urolithiasis varies from region to region. Our study aimed to analyze the impact of extremely high and low temperatures on the number of inpatients for urolithiasis and their lag effect in Ganzhou City, China.MethodsWe collected the daily number of inpatients with urolithiasis in Ganzhou from 2018 to 2019 and the meteorological data for the same period. The exposure-response relationship between the daily mean temperature and the number of inpatients with urolithiasis was studied by the distributed lag non-linear model (DLNM). The effect of extreme temperatures was also analyzed. A stratification analysis was performed for different gender and age groups.ResultsThere were 38,184 hospitalizations for urolithiasis from 2018 to 2019 in Ganzhou. The exposure-response curve between the daily mean temperature and the number of inpatients with urolithiasis in Ganzhou was non-linear and had an observed lag effect. The warm effects (30.4°C) were presented at lag 2 and lag 5–lag 9 days, and the cold effects (2.9°C) were presented at lag 8 and lag 3–lag 4 days. The maximum cumulative warm effects were at lag 0–10 days (cumulative relative risk, CRR = 2.379, 95% CI: 1.771, 3.196), and the maximum cumulative cold effects were at lag 0–5 (CRR = 1.182, 95% CI: 1.054, 1.326). Men and people between the ages of 21 and 40 were more susceptible to the extreme temperatures that cause urolithiasis.ConclusionExtreme temperature was correlated with a high risk of urolithiasis hospitalizations, and the warm effects had a longer duration than the cold effects. Preventing urolithiasis and protecting vulnerable people is critical in extreme temperature environments.

“…The effect was assessed in seven studies. 16,18,19,21,22,43,45 Although none assessed it during cold waves, they did assess it at extremely low centiles. The effects due to low temperatures were studied over the course of the year in four studies 16,19,21,43 and during the cold season in three.…”

“…18,22,45 Generally, the effects were assessed by reference to the MMT, 18,19,21,43,45 and, in one case, 22 by reference to an arbitrary centile (25th centile). The centiles of comparison also varied, with low (<10th centile, 18 <5th centile, 18,19 <2.5th centile 21,43 ) or extreme (<1st centile 18,22,45 ) centiles being used. The effect was likewise assessed for each degree of decrease in the minimum morbidity temperature 16 and by calculating the attributable fraction to non-optimal temperatures.…”

Effect of Temperature on Emergency Ambulance Call-Outs for Cardiovascular Causes: A Scoping Review

2023

View full text Add to dashboard Cite

Climate change has increased interest in the effects of the thermal environment on cardiovascular health. Most studies have focused on mortality data. However, pre-hospital care data are better able to evaluate these effects, as they can register the full spectrum of the disease in real time. This scoping review aims to synthesize the epidemiological evidence regarding the effects of the thermal environment on cardiovascular morbidity in the pre-hospital setting, evaluated through ambulance calls. A staged literature search was performed using the PubMed database for the period between 1st January 2000 and 30th March 2023, using the MeSH terms “Weather” AND “Emergency Medical Services”. A total of 987 publications were identified that examined the correlation between the thermal environment and ambulance call-outs for cardiovascular causes. The studies were mostly ecological time series, with significant variability in the methodological aspects employed. An increase in the number of ambulance call-outs has been observed in association with low temperatures, both for overall cardiovascular pathologies and for certain pathological subtypes. For high temperatures, no effect has been observed in overall call-outs, although an increase has been observed during heat waves. The demand for ambulances for cardiac arrests is increased by both low and high temperatures and during heat waves. Ambulance call-outs for cardiovascular causes increase with low temperatures and heat waves, with no significant increase in the overall demand associated with high temperatures. Ambulance call-outs for cardiac arrests are the only subtype that is increased by high temperatures.

“…Sex/gender is used as an indicator of social vulnerability across multiple settings, though relationship between sex/gender variables and susceptibility is contextual and differs according to climate change impact, health effect and setting (21, 26, 31, 34, 38-40, 43, 51, 53, 54, 60, 61, 63, 64, 66, 69, 71, 72, 76, 78, 79, 82-84, 89, 90, 94, 97, 99, 104, 106, 108, 114, 115, 119, 122, 124, 126, 128, 130-133, 135-157). Extreme temperatures are correlated with increased hypertension (135), ambulance dispatches (133), mortality (34) for men, though this gender health gap had narrowed over time (133). Alternatively, other studies have found women were more vulnerable to temperature variation (40,141), heatwaves (54), cold spells (61) and that the proportion of female population was associated with higher volume of prescription usage for bronchodilator prescriptions (136).…”

This paper is a scoping review of social vulnerability to the health effects of climate change. The review provides an overview of the state of literature on social vulnerability indicators published in English between 2012 and 2022. An initial corpus of 1307 studies were identified from four bibliographic databases (Scopus, Web of Science, PubMed and CAB direct) and after screening 205 relevant studies were identified that contained social vulnerability indicators that mediated between climate change impacts and health outcomes. A frequency analysis was conducted to show the overall scope of the research and a thematic analysis of the results was conducted to examine substantive trends within the literature. A total of 125 indicators of social vulnerability were identified yet a relatively small set of indicators received most of the attention. Indicators that operationalized social vulnerability beyond individual and demographic characteristics were found to be under-researched and needed to further support climate resilience and adaptation planning.
