Varying indoor environmental conditions is known to affect office worker’s performance; wherein past research studies have reported the effects of unfavorable indoor temperature and air quality causing sick building syndrome (SBS) among office workers. Thus, investigating factors that can predict performance in changing indoor environments have become a highly important research topic bearing significant impact in our society. While past research studies have attempted to determine predictors for performance, they do not provide satisfactory prediction ability...

Chronic dehydration (DEH) and heat stress combined with poor cardiovascular (CV) health may influence physiological responses to exercise. We examined the effects of free-living induced hypo-hydration on physiological responses to exercise in a heated environment and whether resting CV health is related to these changes. Participants (N = 16, 20.6 ± 1.2 years) were randomized to 3 days of voluntary fluid restriction (DEH) or intake (hydration [HYD]) followed by an exercise bout. CV health was assessed by flow-mediated dilation (FMD), pulse wave analysis, and heart rate variability (HRV)...

We tested the hypotheses that older adults with cardiovascular co-morbidities will demonstrate greater changes in body temperature and exaggerated changes in blood pressure before initiating thermal behavior. We studied twelve healthy younger adults (Younger, 25 ± 4 y) and six older adults ('At Risk', 67 ± 4 y) taking prescription medications for at least two of the following conditions: hypertension, type II diabetes, hypercholesterolemia. Subjects underwent a 90-min test in which they voluntarily moved between cool (18...

Hot flushes are due to estrogen withdrawal and characterized by the episodic activation of heat dissipation effectors. Recent studies (in humans and rats) have implicated neurokinin 3 (NK3 ) receptor signaling in the genesis of hot flushes. Although transgenic mice are increasingly used for biomedical research, there is limited information on how 17β-estradiol and NK3 receptor signaling alters thermoregulation in the mouse. In this study, a method was developed to measure tail skin temperature (TSKIN ) using a small data-logger attached to the surface of the tail, which, when combined with a telemetry probe for core temperature (TCORE ), allowed us to monitor thermoregulation in freely-moving mice over long durations...

Physical medicine therapies are often used in treating widespread musculoskeletal disorders, such as neck and low back pain. Herbal cataplasms containing rubefacient substances, such as Cayenne pepper, or galenic preparations like Munari cataplasm are commonly used as natural medications to treat painful areas. In this paper we show the effects of a 20-min application of Cayenne pepper and kaolin powder cataplasm (CPC) on healthy subjects. Treatment effects were evaluated by cold/hot feeling on visual analogue scale, blood pressure, body temperature, skin light touch sensations, two-point discrimination, and pain threshold to a mechanical stimulus, before and immediately after, 15 min after and 30 min after different concentration of Cayenne pepper in CPC preparation on healthy subjects...

Objectives: To evaluate the accuracy of detection of temperature differences among skin sites of lay individuals and manual physical therapists. Methods: Forty-four manual physical therapists and 44 lay individuals were recruited. Subjects palpated two temperature-controlled surfaces that ranged in temperature between 30 and 35 °C and varied randomly by 1, 2, 3, 4, or 5 °C for 10 s. The subjects were then asked to identify the warmer pad. Results: Accuracy increased with larger temperature differences...

Aim: Tea is usually consumed at two temperatures (as hot tea or as iced tea). However, the importance of drink temperature on the cardiovascular system and on metabolism has not been thoroughly investigated. The purpose of this study was to compare the cardiovascular, metabolic and cutaneous responses to the ingestion of caffeinated herbal tea (Yerba Mate) at cold or hot temperature in healthy young subjects. We hypothesized that ingestion of cold tea induces a higher increase in energy expenditure than hot tea without eliciting any negative effects on the cardiovascular system...

PURPOSE: Radiotherapy is a common adjuvant treatment of breast cancer. Acute radiation-induced dermatitis is a frequent side effect. We hypothesized whether it is possible to capture the increase of local temperature as a surrogate of the inflammatory state induced by radiotherapy. We designed a prospective, observational, single-centre study to acquire data on temperature rise in the treated breast during the course of radiotherapy, establish a possible association with the occurrence of dermatitis and investigate the predictive value of temperature increase in future occurrences of radiation-induced dermatitis...

The present work analyzes skin burns from spills of hot rice and milk products. The traditional Norwegian rice porridge serves as an example. By testing spills on objects emulating an arm, it was concluded that spills were seldom thinner than 3 mm, and stayed in place due to the viscosity of the porridge for more than one minute. The Pennes bioheat equation was solved numerically for such spills, including heat conduction to the skin and convective heat losses from the porridge surface. Temperatures were analyzed in the porridge and skin layers, and the resulting skin injury was calculated based on the basal layer temperature...

Hemodialysis (HD) is a lifesaving treatment for patients with end-stage renal disease, which is very efficient in the correction of abnormalities of the internal environment. However, this efficiency also induces significant hemodynamic, thermal, and respiratory stressors. These have parallels with the extreme physiologic demands which are normally mainly experienced by healthy subjects under adverse environmental conditions, with the difference that they must be endured by a vulnerable patient population. Hemodynamic stress induced by ultrafiltration leads to a decline in circulating blood volume, which may result in intradialytic hypotension (IDH) and changes in tissue perfusion, which may have long-term consequences for the function of vital organs such as the brain and the heart...

Fifteen adult koi (Cyprinus carpio) simultaneously developed white cutaneous proliferations affecting up to 30% of their bodies. Onset of lesions (September, 2014) was associated with return to a remodeled backyard water garden after temporarily being maintained in a plastic swimming pool. A single water temperature taken during the outbreak read 21°C on November 17, 2014. The water garden was under no extrinsic heat source, with average ambient temperatures ranging from 26.4-9.4 °C during the course of the outbreak (September 2014-January 2015, respectively)...

BACKGROUND: Surgical site infection (SSI), the third most common type of nosocomial infection in Sweden, is a patient injury that should be prevented. Methods of reducing SSIs include, for instance, disinfecting the skin, maintaining body temperature, and ensuring an aseptic environment. Guidelines for most of these interventions exist, but there is a lack of studies describing to what extent the preventive interventions have been implemented in clinical practice. We describe the daily clinical interventions Swedish operating room (OR) nurses performed to prevent SSIs following national guidelines...

Interferon-beta (IFNβ) are effective treatments for relapsing multiple sclerosis. IFNβ treatment includes subcutaneous (sc) IFNβ-1b, intramuscular and sc IFNβ-1a, and sc pegylated IFNβ-1a (PEG-IFNβ-1a). PEG-IFNβ-1a offers the advantage of a prolonged duration of action with a less frequent administration (every 2 weeks) and a higher patient adherence. However, the use of subcutaneous interferons could be characterized by potential skin toxicity. Injection site reactions (ISRs), featured by erythema, edema, pain and pruritus, are the most common adverse reactions...

Heat stress (HS) is one of the limiting factors negatively affecting pig production, health, and fertility. Characterizing genomic regions responsible for variation in HS tolerance would be useful in identifying important genetic factor(s) regulating physiological responses to HS. In the present study, we performed genome-wide association analyses for respiration rate (RR), rectal temperature (TR) and skin temperature (TS) during HS in 214 crossbred gilts genotyped for 68,549 single nucleotide polymorphisms (SNP) using the Porcine SNP 70K BeadChip...
