Introduction: Various investigations have established the relationship between temperature and duration of pregnancy. Exposure to high temperatures during pregnancy raises questions, especially the role it plays in premature births and low-weight births. It is essential to determine whether high temperatures or low have a protective or risky behavior on the fetus during pregnancy in tropical regions.Objective: to describe the relationship between exposure to high and low temperatures during pregnancy and its effect on gestational age and weight at the time of delivery in newborns in the department of Guaviare-Colombia.Methodology:Observational, analytical, retrospective cross-sectional study that sought to determine the relationship between exposure to high and low temperatures during pregnancy and its effect on gestational age and weight at the time of delivery in newborns. The universe was made up of 10,137 births. alive, of which 9,932 met the inclusion criteria. Odds Ratio was determined to estimate the association between the variables.Results:Within the 3rd week of delay, being exposed to maximum temperatures at the 90th percentile is a protective factor for weight gain OR < 1, exposure to minimum temperatures at the 10th percentile was associated as a protective factor for premature birth in the week. of delay 1 and 2 OR < 1. Conclusion: Despite the benefit of high and low temperatures during pregnancy in weight gain and reduction in premature birth, it is advisable to prevent exposure to extreme temperatures during the gestation period[AU]

La salud humana frente al estrés térmico por el cambio climático

Introducción: La alteración del clima planetario, atribuida directa o indirectamente a la actividad humana, que modifica la composición de la atmósfera mundial y se suma a la variabilidad natural del clima, es conocida como cambio climático global. Sus efectos en la salud, directos e indirectos, ya presentes, perturbarán a la mayoría de las poblaciones en las próximas décadas y pondrán en riesgo la vida y el bienestar de miles de millones de personas. Objetivo: Describir, a partir de una revisión, los principales riesgos para la salud humana derivados de la mayor frecuencia e intensidad de episodios de estrés térmico derivados del cambio climático. Métodos: Se realizó una revisión bibliográfica relativa a los efectos de la temperatura sobre la salud humana, así como su influencia sobre la mortalidad general, en el periodo 2008 hasta 2021, en las bases de datos Scopus, PubMed/Medline, SciELO, Ebsco, LiLACS, así como, otras fuentes y recursos de información disponibles en Internet. Se utilizó el vocabulario controlado del Descriptor en Ciencias de la Salud. Resultados: Se recuperaron 32 publicaciones sobre de la influencia del clima y sus cambios en la salud humana que plantearon, por lo general, que las altas temperaturas guardaron relación con el incremento de la mortalidad principalmente por enfermedades cardiovasculares, cerebrovasculares y respiratorias, se han convertido en un contribuyente considerable a la carga de morbilidad. Conclusiones: Las temperaturas extremas incrementan la morbilidad y mortalidad agudas, principalmente en grupos de riesgo. La promoción de una adecuada hidratación y el uso de ropas adecuadas, ayudará a las personas en la prevención de afecciones por las temperaturas extremas, erigiéndose en acciones individuales de protección contra los efectos de la mayor frecuencia e intensidad de eventos de estrés térmico asociado al cambio climático, a incorporar a la cotidianidad.

Introduction: The alteration of the planetary climate, attributed directly or indirectly to human activity, which modifies the composition of the world atmosphere and adds to the natural variability of the climate, is known as global climate change. Its direct and indirect health effects, already present, will disturb most populations in the coming decades and put the lives and well-being of billions of people at risk. Objective: To describe, based on a review, the main risks to human health derived from the greater frequency and intensity of episodes of thermal stress derived from climate change. Methods: A bibliographic review was carried out regarding the effects of temperature on human health, as well as its influence on general mortality, in the period 2008 to 2021, in the Scopus, PubMed/Medline, SciELO, Ebsco, LiLACS, as well as other information sources and resources available on the Internet. The controlled vocabulary descriptors in Health Sciences were used. Results: 32 publications on the influence of climate and its changes on human health were recovered, which generally stated that high temperatures were related to the increase in mortality, mainly due to cardiovascular, cerebrovascular and respiratory diseases, and have become a significant contributor to the burden of disease. Conclusions: Extreme temperatures increase acute morbidity and mortality, mainly in risk groups. The promotion of adequate hydration and the use of adequate clothing will help people in the prevention of conditions caused by extreme temperatures, establishing individual actions to protect against the effects of the greater frequency and intensity of heat stress events associated with climate change, to incorporate into daily life.

Plugger temperature of cordless heat carriers according to the time elapsed

OBJECTIVE: The purpose of this study was to measure the temperature of the plugger tip of 3 cordless heat carriers set at 200°C. MATERIALS AND METHODS: Pluggers of the same taper (0.06, 0.08, 0.10) and similar tip sizes (sizes of 50 and 55) from 3 cordless heat carriers, namely SuperEndo-α2 (B & L Biotech), Friendo (DXM), and Dia-Pen (Diadent), were used and an electric heat carrier, System B (SybronEndo), was used as the control. The plugger tips were covered with customized copper sleeves, heated for 10 seconds, and the temperature was recorded with a computerized measurement system attached to a K-type thermometer at room temperature (n = 10). The data were analyzed with 2-way analysis of variance at a 5% level of significance. RESULTS: The peak temperature of the plugger tips was significantly affected by the plugger taper and by the heat carrier brand (p < 0.05). The peak temperature of the plugger tips was between 177°C and 325°C. The temperature peaked at 207°C–231°C for the 0.06 taper pluggers, 195°C–313°C for the 0.08 taper pluggers, and 177°C–325°C for the 0.10 taper pluggers. Only 5 of the 12 plugger tips showed a temperature of 200°C ± 10°C. The time required to reach the highest temperature or 200°C ± 10°C was at least 4 seconds. CONCLUSION: When using cordless heat carriers, clinicians should pay attention to the temperature setting and to the activation time needed to reach the intended temperature of the pluggers.

The clinical value of combining early peak temperature with 48 h-△sequential organ failure assessment score in predicting prognosis for patients with sepsis in emergency department / 中华急诊医学杂志

Objective To investigate the joint value of early peak temperature and 48 h-△sequential organ failure assessment (SOFA) score in predicting the prognosis for patients with sepsis in emergency department.Methods Two hundred and thirty-one patients with sepsis admitted from January 2013 to January 2015 in Emergency Intensive Care Unit of the First Affiliated Hospital of China Medical University were enrolled.Clinical features,early peak temperature,SOFA scores,the length of stay in EICU and the mortality in 28 days were studied.The patients were divided into two groups according to the 48 h-△SOFA.Each group were divided into three subgroups according to the early peak temperature.For example,hypothermia subgroup had temperature below 36 ℃,normothermia subgroup had temperature between 36 ℃ and 38 ℃,and hyperthermia subgroup had temperature above 38 ℃.The relationship between peak temperature plus 48 h-△SOFA and the length of stay in EICU as well as mortality were analyzed.Results Of 231 patients,in 48 h-△SOFA＞0 group (n =142) 27 (19.0％) patients died,and in 48 h-△SOFA≤0 group (n =89) 33 (37.1％) patients died (P ＜ 0.05).Hypothermia subgroup had a higher odds ratio value in predicting nonsurvival in 48 h-△SOFA≤0 group (OR =4.51,95％CI:1.33-2.17,P =0.01).Hyperthermia subgroup had a longer stay in EICU than hypothermia subgroup and normothermia subgroup (P ＜ 0.05).Conclusion The combination of the early peak temperature and 48h-△SOFA score is an effective indicator to evaluate the prognosis and to stratify patients with sepsis in emergency department.More attention should be paid to the patients with an early peak temperature ＜ 36 ℃ and 48 h-△SOFA ≤0 because of higher mortality.The condition of patients should be reassessed and try to make a more rational treatment for the patients with an early peak temperature ＞38 ℃ and 48 h-△SOFA ＞0 because of its longer stay in EICU.
