Article Abstract
Currently, numerous thermal comfort models have been proposed; however, research on the combination of different models is lacking. This study aims to predict the overall thermal sensation (OTS*) and thermal comfort (OTC*) with different model combinations under hot and cold step changes. Three cold- and hot-shock processes are designed in the climate chamber. Accordingly, the skin temperature, thermal sensation, and thermal comfort votes of 16 participants are collected. The impacts of winter hot and cold step changes on subjective votes and skin temperatures are evaluated. Further, the OTS* and OTC* values are calculated, and their accuracy under different model combinations is analyzed. The results reveal that thermal sensation changes in human body exhibit distinct asymmetry under the cold and hot step-changes, except for the cycle of "15-30-15 °C" (I15). The parts farther from the core area become more asymmetrical after the step changes. The single models exhibit the highest accuracy in different model combinations. The combined form of a single model is recommended for thermal sensation or comfort prediction.

Introduction: To improve the work efficiency and reduce heat-related illness of emergency rescue personnel, the effects of emergency rescue clothing on physiological and perceptual responses were investigated.
Methods: Thirteen participants were recruited to perform human trials in a climate chamber wherein the ambient temperature and relative humidity was controlled at 35°C and 75%, and 25°C and 65%, respectively. Moreover, participants wearing emergency rescue clothing (ERC group) and T-shirts and shorts (CON group) walked at 4 and 6 km/h on a treadmill.
Structured Symptom Assessment to Identify Patients With Small Fiber or Autonomic Neuropathy in Fibromyalgia.

Background: Fibromyalgia (FM) is a complex chronic pain disorder characterized by widespread musculoskeletal pain and symptoms suggesting autonomic dysfunction. Small fiber neuropathy (SFN) has been described in a subgroup of patients. We aimed to explore the value of structured symptom assessment to identify patients with SFN or autonomic neuropathy.

Maintenance of core temperature (Tc) is vital for health and physiological function while SCUBA diving in cold water, but there is little research investigating the influence of anthropometrics, suit type, and sex on the rate of change in Tc during real-world diving conditions. We measured the rate of change in Tc (telemetric pill) and thermal sensation (Ts; Young questionnaire) in 62 participants (32 female) before and after non-decompression SCUBA dives using open circuit apparatus breathing air at varied depths and durations in cold water (~ 10 °C). Twenty-three participants wore drysuits (11F), and 39 participants wore wetsuits (21F).

Aims: To evaluate somatosensory function changes and recovery time in patients with mandibular edentulous jaw after full arch flap implant surgery using a standardized quantitative sensory testing (QST) protocol.
Materials And Methods: Fourteen patients with edentulous mandibles underwent full-arch alveolar flap implant surgery, with three to four implants placed in each case. A QST battery including cold detection threshold (CDT), warmth detection threshold (WDT), thermal sensory limen (TSL), paradoxical heat sensation (PHS), cold pain threshold (CPT), heat pain threshold (HPT), mechanical detection threshold (MDT), mechanical pain threshold (MPT), wind-up ratio (WUR), vibration detection threshold (VDT), and pressure pain threshold (PPT) was performed at skin of mental region and keratinized gingiva of right canine.
Incorporating thermoreceptor responses in a local sensation model to account for setpoint adaptation during cold-to-warm transition.

The Berkeley comfort models are well-suited for addressing nonuniform, transient, and cold conditions owing to their comprehensible model structures. Integrating these models with thermoregulation models can aid in formulating energy-efficient local warming and heating, ventilation, and air conditioning (HVAC) operational strategies for occupant-centric winter conditioning in battery electric vehicles (BEVs)-a critical step toward their widespread adoption. However, the Berkeley local sensation (LS) model requires accurate consideration of setpoint and setpoint adaptation to ensure reliable predictions.
