“…Air temperature, especially cold temperature, has a short-term effect on blood pressure (Xu et al, 2019) because exposure to cold temperatures can increase activation and vasoconstriction of the sympathetic nervous system, and reduce endothelial function, which can lead to increased blood pressure (Park et al, 2020). The results of this study are in line with the findings showing that the percentage of patients with large-artery atherosclerosis (LAA) in the low-temperature group was significantly greater than that in the non-low-temperature group (p<0.05) because low temperatures can cause an increase in platelets and red blood cells, as well as increase blood viscosity, adhesion and platelet activation, all of which can lead to thrombosis (Chen et al, ), 2021Chen, Shang, et al, 2019;Halil Gibran & Heriyani, 2020;Hartwig et al, 2021;Jayarajah & Seneviratne, 2019;Karim et al, 2021;Polcaro-Pichet et al, 2019;Tochihara et al, 2021;Toffoli et al, 2023;Umishio et al, 2019;Wu et al, 2021a).…”

“…The diseases caused by exposure to air temperature mentioned above are related to the fact that the human body should be busy during the day and needs sleep at night to restore energy and heal. Some studies also explain that the temperature of the work environment, especially cold temperatures, can increase blood pressure (Chen et al, 2021;Chen, Shang, et al, 2019;Chen, Xue, et al, 2019;Halil Gibran & Heriyani, 2020;Hartwig et al, 2021;Jayarajah & Seneviratne, 2019;Karim et al, 2021;Park et al, 2020;Polcaro-Pichet et al, 2019;Tochihara et al, 2021;Toffoli et al, 2023;Umishio et al, 2019;Wu et al, 2021a). However, there are research findings from Grace et.al, (2017) which state that there is a significant relationship between exposure to cold air temperatures and changes in systolic and distolic blood pressure before and after work.…”

The human body regulates its temperature to normal levels when exposed to cold temperatures, which allows it to adjust to changes in its surroundings. The force of blood that the heart pumps against the artery walls is called blood pressure. Variations in fishermen's blood pressure may be affected by the cold working environment. The purpose of this study was to determine the comparison of blood pressure before and after exposure to air temperature in fishermen workers. With a single group pretest-posttest quantitative research methodology, this study used an experimental pre-research design. Univariate data analysis, bivariate using the Wilcoson test and multivariate using MANOVA testing. The study population was 57 fishermen of Tanjung Tiram District. By using the basic random selection approach, the research sample amounted to 50 respondents. Data collection using primary data obtained directly from fishermen workers on the Tanjung Tiram coast using digital tension meters and observation sheets. The analytical tool used is SPSS. The results showed that there was a comparison of blood pressure before and after exposure to air temperature, meaning that exposure to air temperature can increase blood pressure both systole and diastole, so maintaining health is needed for workers who work as fishermen.

“…Cold temperatures are associated with high UF rates, which are a risk factor for SBP decline and thus more likely to meet the criteria of Fall40. In addition, cold temperatures are linked to higher pre-HD SBP [ 35 , 36 ], which may make individuals less likely to reach Nadir90/100 criteria, as the lowest intradialytic SBP determines it. Our results suggest that Fall40 is more sensitive to cold ambient temperatures.…”

Background Intradialytic hypotension (IDH) is a common hemodialysis complication causing adverse outcomes. Despite the well-documented associations of ambient temperatures with fluid removal and pre-dialysis blood pressure, the relationship between ambient temperature and IDH has not been adequately studied. Methods We conducted a cohort study at a tertiary hospital in southern Taiwan between January 1, 2016 and October 31, 2021. The 24-hour pre-hemodialysis mean ambient temperature was determined using hourly readings from the weather station closest to each patient's residence. IDH was defined using Fall40 (systolic BP drop of ≥ 40mmHg) or Nadir90/100 (systolic BP<100 if pre-dialysis systolic BP was ≥ 160, or systolic BP <90 mmHg). Multivariate logistic regression with generalizing estimating equations and mediation analysis were utilized. Results The study examined 110,400 hemodialysis sessions from 182 patients, finding an IDH prevalence of 11.8% and 10.4% as per the Fall40 and Nadir90/100 criteria. It revealed a reverse J-shaped relationship between ambient temperature and IDH, with a turning point around 27°C. For temperatures under 27°C, a 4°C drop significantly increased the odds ratio of IDH to 1.292 (95% confidence interval (CI) 1.228 to 1.358) and 1.207 (95% CI 1.149 to 1.268) under the Fall40 and Nadir90/100 definitions, respectively. Lower ambient temperatures correlated with higher ultrafiltration, accounting for about 23% of the increased IDH risk. Stratified seasonal analysis indicated that this relationship was consistent in spring, autumn, and winter. Conclusion Lower ambient temperature is significantly associated with an increased risk of IDH below the threshold of 27°C, irrespective of the IDH definition. This study provides further insight into environmental risk factors for IDH in patients undergoing hemodialysis.

“…Recent studies ( 16 , 17 ) have shown that intradialytic hypotension is associated with patient prognosis and is an independent risk factor for high hospitalization rates in MHD patients, as well as reduced survival; intradialytic hypertension is an independent risk factor for increased mortality in MHD patients. There are numerous studies on the mechanisms of combined hypertension on dialysis, while the main mechanism for the occurrence of blood pressure fluctuations during dialysis is not clear ( 18 ). Meanwhile, the smooth control of blood pressure during dialysis in MHD patients has great significance for improving the prognosis of dialysis patients and improving the quality of survival of dialysis patients.…”

Correlation of NO and ET-1 Levels with Blood Pressure Changes in Hemodialysis Patients after Arteriovenous Fistula Surgery

Hemodialysis (HD) is the most common renal replacement therapy for patients with end-stage renal disease (ESRD) and can significantly reduce mortality and improve the quality of life of patients. The occurrence of intradialytic hypotension and intradialytic hypertension are important risk factors for death and disability during dialysis in patients with ESRD, yet their etiology remains unclear, and some studies suggest that nitric oxide (NO) and endothelin-1 (ET-1) may play an important role in these hemodynamic alterations. For this purpose we examined the changes in NO and ET-1 levels during hemodialysis in 30 patients on maintenance hemodialysis (MHD) after arteriovenous fistula surgery. Thirty dialysis patients were divided into group I (stable blood pressure during dialysis), group II (Intradialytic hypotension) and group III (Intradialytic hypertension) according to the change of blood pressure (BP) during hemodialysis, with 10 cases in each group. BP of MHD patients were measured Pre-dialysis (Pre-D), at 1 h of dialysis (1h-D), at 2 h of dialysis (Mid-D, 2h-D), at 3 h of dialysis (3h-D), and at the end of dialysis (Post-D); and blood samples were taken from the arterial end at Pre-D, Mid-D, and Post-D to measure NO and ET-1 levels. The results of the analysis showed that as dialysis proceeded and ended, the NO levels in the three groups gradually decreased, with significant differences compared with those before dialysis (p < 0.05); the ET-1 levels in group III gradually increased, with significant differences compared with those before dialysis (p < 0.05), while the increasing trend of ET-1 levels in group I and group II was not significant. The increasing trend of MAP in group I was not significant (p > 0.05); MAP in group II showed a gradual decrease and MAP in group III showed an increasing trend, and the difference between MAP after dialysis and before dialysis was significant (p < 0.05). Correlation analysis showed a significant positive correlation between ET-1 levels and MAP in Group III at Mid-D (r = 0.847, p = 0.002). This shows that serum ET-1 and NO levels are significantly higher than normal in MHD patients after arteriovenous endovascular fistula surgery, and both ET-1 and NO levels are changing during dialysis, and there may be a link between their changes and blood pressure changes. It is suggested that the blood pressure fluctuations that occur during dialysis in MHD patients may be related to endothelial cell dysfunction.
