Core body temperature data were collected over the course of the workday for 128 agricultural workers in Guatemala from December 2021 to April 2023. Concurrently, measures of heat-related health effects (reduced kidney function, muscle breakdown, and dehydration) were collected. Using linear mixed-effect regression models we assessed the performance of 14 summary measures of core body temperature on the heat-related health effects of interest. Model performance was compared using AIC and BIC. There was no consistent summary statistic that provided the best fit based on AIC or BIC for all four heat-related health effects. The difference between the observed CBT and the average of the first 60 min of the cleaned workday data (delta) provided the best performance for percent change in creatine kinase (muscle breakdown), serum creatinine (reduced kidney function), and serum osmolality (dehydration).

This study evaluates the short-term clinical efficacy of peloid therapy, a form of balneotherapy, in managing CLBP in a large monocenter cohort of patients. Conducted at the Samsun Training and Research Hospital, it retrospectively analyzed data from patients treated between October 2022 and October 2024. A total of 263 patients underwent peloid therapy for 7 to 15 days. The physicochemical properties of the peloid used were analyzed, and outcome measures included the Health Assessment Questionnaire (HAQ), Oswestry Disability Index (ODI), and Visual Analog Scales (VAS) for pain, patient global assessment (VAS-PGA), and physician global assessment (VAS-PhGA). Pre- and post-treatment comparisons were performed using paired t-tests and repeated measures ANOVA. Multiple linear regression was used to identify predictors of treatment response. Statistically significant improvements were observed in all outcome measures post-treatment (p < 0.001). HAQ scores decreased from 0.99 ± 0.52 to 0.48 ± 0.41, ODI scores from 54.6 ± 21.0 to 34.7 ± 18.5, and all VAS scores showed significant reductions, with large effect sizes (Cohen's d > 1.0). Longer treatment duration and being non-working were associated with greater improvements in HAQ and ODI scores. No significant influence was observed for gender, obesity, smoking status, or comorbidities. The study highlights the potential of peloid therapy as an effective, non-pharmacological treatment for CLBP, offering a cost-effective and accessible alternative within the Turkey healthcare system.

While previous research in the region has predominantly focused on heat-related mortality, this study provides a comprehensive quantitative analysis of cold-related mortality using daily data and a multi-method statistical approach. Cold days were defined as those with an average temperature below 0 °C, and cold spells were defined as periods with at least three consecutive days with minimum temperatures at or below - 10 °C. The results confirm a statistically significant increase in mortality during both cold days and cold spells. Nonlinear models, particularly LOESS and quadratic regression, identified two inflexion points in mortality response: at - 3.5 °C (onset of increase) and - 7 °C (marked escalation), with the highest mortality observed below - 13 °C, though based on fewer observations. The analysis of temporal lags revealed that mortality tends to increase between 2 and 9 days following cold exposure, with the most pronounced effects occurring during cold spells. Compared to Poisson regression, which failed to capture these associations, nonlinear methods more accurately reflect cold-related mortality dynamics. The study also proposes that - 7 °C is the most reliable operational threshold for early warning systems, given its consistency across models and statistical significance.

Additionally, the work assesses the effect of material air permeability and the influence on insulation at the various environmental conditions. A systematic approach revealed that material air permeability was primarily related to forced convective heat transfer and requires a minimum air layer thickness of 5 mm and wind speed of 1.3 m/s to be observed. Additionally, it was found that traditional methods of evaluating material thickness, such as ASTM D1777, apply a high force to the material and do not give an accurate measurement of uncompressed thickness- which is more indicative of what would be experienced during normal wear conditions.

Our systematic literature search identified 4,681 publications on phenology between 1989 and 2019. We showed taxonomic and geographic bias in the literature with a large proportion of publications on bird migration and reproduction, insect phenology, marine phenology, and agriculture, focused within the Northern hemisphere. Our results reflected the decadal advances in technology, for example remote sensing studies increased the most in popularity. Topics related to genetics increased along with mismatching, which has impacts on species fitness. While climate-based topics were highly connected, there was little connectivity between different disciplines and newer areas of research. Remote sensing rarely co-occurred with other topics, insect phenology was either being studied with plants or birds instead of being considered as part of a network, and mismatching was rarely studied alongside other methodologies in phenological research. We suggest that transdisciplinary research considering species as part of a system and analyzing new or understudied taxa and regions should be prioritized.
