Recommendations for Updating Fever and Inflammation of Unknown Origin From a Modified Delphi Consensus Panel.

Fever of unknown origin (FUO) and inflammation of unknown origin (IUO) are syndromes commonly used as medical diagnoses. Since the existing literature has a mixture of diagnostic approaches, developing consensus-based recommendations would be helpful for clinicians, researchers, and patients. A modified Delphi process was performed from October 2022 to July 2023, involving 4 rounds of online surveys and 2 live video conferences. The panel comprised international experts recruited based on peer-reviewed published publications and studies. Among 50 invited experts, 26 (52.0%) agreed to participate. Twenty-three panelists completed round 1 of the survey, 21 completed rounds 2 and 3, 20 completed round 4, and 7 participated in round 5 live video discussions. Of the participants, 18 (78.3%) were academic-based clinicians and researchers, 5 (21.7%) practiced in a community-based hospital, and 6 (26.1%) were female. Consensus was reached on 5 themes: (1) incorporating epidemiologic factors, such as geographic location and travel history; (2) updated criteria for classifying FUO or IUO; (3) initial evaluation approaches; (4) a classification system for diagnoses; and (5) recommendations for judicious limitation of empiric therapies. Experts strongly disagreed with using 2-deoxy-2-[18F] fluoro-D-glucose positron emission tomography/computed tomography as part of the diagnostic criteria for FUO. There were mixed opinions about the importance of the temperature measurement site, the 3-week minimum illness criterion, the need for a standard definition of relapsing fevers, and the use of similar evaluation strategies for FUO and IUO. These Delphi-generated consensus-based recommendations offer potential improvements compared with earlier definitions and a guide for clinical practice and future research.

Reliability of udder infrared thermography as a non-invasive technology for early detection of sub-clinical mastitis in Sahiwal (Bos indicus) cows under semi-intensive production system

The present study focused on Sahiwal cows, a prominent milch breed in tropical India, to correlate udder temperature with physiological markers of stress and inflammation during subclinical mastitis (SCM). The primary goal was to assess the potential of udder infrared thermography for the early detection of SCM under the semi-intensive production. Cows were categorized based on milk somatic cell counts (SCC), with healthy (H) cows having SCC <2 × 105 cells/mL and no history of mastitis, and cows with subclinical mastitis (SCM) and initial stages of clinical mastitis (CM) having quarter milk SCC of 2–5 × 105 and >5 × 105 cells/mL, respectively. Firstly, udder thermograms were analysed for udder skin surface temperature (USST), teat skin surface temperature (TSST), and teat apex temperature (TAT) using Fluke software to determine the optimal site for temperature measurement during intramammary infection. Secondly, milk samples were collected for automatic estimation of compositional changes, electrical conductivity, and pH. Thirdly, milk whey was separated for quantifying stress and inflammatory indicators, including cortisol, prolactin, and acute-phase proteins (APPs): milk amyloid A and milk haptoglobin using bovine-specific ELISA kits. Significant increases (p < 0.01) in USST, TSST, TAT, cortisol, and APPs were observed in SCM and CM compared to healthy cows, while prolactin levels decreased (p < 0.01). The correlation matrix revealed strong positive correlations of SCC with USST (r = 0.84, p < 0.01). In ROC analysis, USST demonstrated cut-off values of 37.74 and 39.58 °C, with accuracy (p < 0.05) of 98% for SCM and 95% for CM, surpassing both TAT and TSST. Therefore, the combination of these non-invasive methods increases the reliability and accuracy of infrared thermography for early detection of SCM, providing valuable insights for the development of a protocol for routine screening and udder health monitoring in indigenous dairy cows.

Evaluating alternative temperature measurement sites in cats within a home environment: A comparison with rectal temperature.

This study aimed to compare rectal temperature (RT) with temperatures measured in the pinna, cornea, medial canthus, gingiva, metacarpal pad and axillary region of cats in a home environment. Five healthy mixed-breed cats (two females and three males) owned by a veterinarian were used. All temperature measurements were conducted by the owner by using an infrared camera in the same room and initiated with the pinna, followed by the cornea, medial canthus, gingiva and metacarpal pad. Subsequently, axillary temperature (AT) and RT were recorded by a digital thermometer, respectively. The time taken for a single AT and RT measurements was recorded. The average measurement time for RT was 17.34±0.89s, with a range of 8-32s, whereas AT measurements took an average of 46.72±1.16s, with a range of 29-69s. AT emerged as a superior alternative measurement site compared to others, exhibiting the lowest bias and the highest proportion of readings within the limits of clinical agreement. The mean difference between RT and AT, with 95% limits of agreement for the differences, was -0.26 (-1.13 to 0.61). Anatomical regions were not all interchangeable with the rectum for assessing body temperature (BT), with AT recording the highest level of agreement with RT. When RT is not possible, AT could be considered as an alternative for monitoring BT in clinically healthy cats that live in a home environment.

Assessment of preferable site for temperature measurement using non-contact infra-red temperature among pediatric patients.

Accurate temperature measurement with little or no discomfort that is safe, without risk of hospital-acquired infections or perforations, is the preferred choice of medical professionals in pediatric settings. The objective was to discover the preferable site for body temperature measurement using non-contact infra-red thermometer (NCIT) among pediatric patients. NCIT measurement at mid forehead (F), right temporal region (T), right side of neck-over-carotid artery area (N), jugular notch (J), sternum (S), umbilical region and sublingual region (U) were compared with digital axillary temperature (DAT) in a single attempt in 500 patients, aged between 2 to 5 years with fever. Data was analyzed using Pearson's correlation, paired t-test and Bland-Altman plot to assess the correlation and agreement between the DAT and NCIT sites. The mean temperature of NCIT-T (38.42±0.64 °C) was more agreeable with DAT (38.42±0.63 °C) compared to other body sites. The minimum mean bias of -0.00480 °C was noted for NCIT-F with 95% CI of -0.164-0.15; however, NCIT-F revealed many outliers as compared to NCIT-J. A strong positive correlation existed between DAT and NCIT sites (r value: 0.99-0.98). However, significant difference was found between DAT and NCIT-N, NCIT-F and NCIT-U (P<0.0001). NCIT-J is the most preferable choice for measuring body temperature and can be interchanged with DAT. It will help to deliver fast results with enhanced patient comfort due to its non-invasive nature.

Simulation and Validation of Thickness of Slag Crust on the Copper Stave in the High-Temperature Area of Blast Furnace

The blast furnace is the dominant high-temperature reactor in the modern ironmaking industry. Iron oxide in iron ores can be converted to metallic iron through blast furnace smelting, and this high-temperature melting can be used to separate the molten iron from the gangue components. The formation and thickness of the hot-surface slag crust on the copper stave in the high-temperature area of the middle and lower parts of the blast furnace are crucial for the safe operation and long campaign of the blast furnace. To enhance the precision of determining the thickness of the slag crust in this specific region, samples were extracted from the hot surface of the copper cooler situated in the high-temperature area. This extraction was carried out during the maintenance procedure of the blast furnace stockline. Subsequently, the thermal conductivity and melting performance of the slag crust were measured. The slag crust thicknesses corresponding to the various temperature measurement sites of the stave were determined by developing a mathematical model for the heat transfer of the copper stave. The actual slag crust thickness measurement data were acquired while the blast furnace stockline was in operation, and the data were then utilized to corroborate the model’s predictions. A blast furnace with an effective volume of 3200 m3 was used to test the model. The average thickness of the hot-surface slag crust was computed for cases that occurred between 2020 and 2022. The data’s correlations with the blast furnace’s technical and economic indices during the same time period were examined. The findings indicated that the blast furnace’s operation indices improved with a thinner slag crust, but there was also a higher chance of damage to the copper stave’s internal cooling water pipes. Taking into account the technical and economic indices as well as a long campaign of the blast furnace, 150–200 mm is recommended as the appropriate average slag crust thickness on the surface of the copper stave in the high-temperature section.

Spatial development indicators as a tool to determine thermal conditions in an urban environment

In the face of climate change and the growing frequency of thermally burdensome conditions, urban morphology and city planning are becoming increasingly important to human health. Architects and policymakers use various tools, including spatial development indicators describing the characteristics of built-up areas, to mitigate urban climate. This study purposed to (1) indicate which widely used spatial development indicators most adequately explained the thermal conditions of the environment, and (2) investigate how large an area most accurately represents the thermal features recorded at a given air temperature measurement site. Selected indexes were used to characterize each of the 21 measuring sites located in Warsaw. First, five spatial development indicators were calculated for three distances from each site. Then, based on data from the air temperature monitoring network, 17 selected thermal characteristics were calculated. The results of the analyses indicated that the Ratio of Biologically Vital Area has the highest impact on the thermal regime with particularly strong influence on the lowest daily temperature values. The paper proves that the thermal conditions of a given location in the diverse space of a city are more precisely represented by a large area than by its nearest surroundings.

A comparison of rectal versus fetlock temperatures in dorsally recumbent horses during general anesthesia

ObjectiveTo investigate the effect of isoflurane anesthesia on thermoregulation and peripheral heat loss in dorsally recumbent horses. Study designProspective, clinical study. AnimalsSeven adult horses (2.6 ± 1.5 years old, 455 ± 70.2 kg). MethodsHorses underwent elective surgical procedures in dorsal recumbency under general anesthesia (GA) maintained with isoflurane in oxygen. Rectal (TR), intranasal (TN) and fetlock surface temperatures (TF) were measured every 10 minutes for the first 80 minutes following induction of GA. Room temperature (TRO) was monitored during the study. Statistical analysis to determine differences between temperature measurement sites and techniques (TR, TN and TF), and differences over time were completed using a mixed-effects model with Tukey’s multiple comparison or Dunnett’s multiple comparison testing where appropriate. Significance was set at p < 0.05. ResultsFollowing induction of anesthesia, TF was significantly increased compared with baseline (0 minutes) from 40 to 80 minutes (p < 0.01). No significant differences were detected in TR and TN at any time point compared with baseline (p > 0.05). TF was significantly lower than TN (p < 0.02) at all time points and TR from times 0 to 70 minutes (p < 0.04). There were no significant differences between TR and TN at any time (p > 0.05). ConclusionsIn horses undergoing isoflurane GA, TF increased, indicating peripheral heat loss likely because of vasodilation, whereas TR showed a clinically relevant decrease over time. These findings are suggestive of body heat redistribution during GA in horses in dorsal recumbency. Thermographic imaging of the peripheral limbs in combination with TR and TN monitoring allowed for recognition of peripheral heat redistribution in anesthetized horses. Clinical relevanceAnesthetized horses experience peripheral heat loss through their extremities as a result of vasodilation. Mitigating peripheral heat loss may improve thermoregulation and reduce hypothermic complications in anesthetized horses.

Heat Adaptation and Nutrition Practices: Athlete and Practitioner Knowledge and Use.

To survey elite athletes and practitioners to identify (1)knowledge and application of heat acclimation/acclimatization (HA) interventions, (2)barriers to HA application, and (3)nutritional practices supporting HA. Elite athletes (n = 55) and practitioners (n = 99) completed an online survey. Mann-Whitney U tests (effect size [ES; r]) assessed differences between ROLE (athletes vs practitioners) and CLIMATE (hot vs temperate). Logistic regression and Pearson chi-square (ES Phi [ϕ]) assessed relationships. Practitioners were more likely to report measuring athletes' core temperature (training: practitioners 40% [athletes 15%]; P = .001, odds ratio = 4.0, 95% CI, 2%-9%; competition: practitioners 25% [athletes 9%]; P = .020, odds ratio = 3.4, 95% CI, 1%-10%). Practitioners (55% [15% athletes]) were more likely to perceive rectal as the gold standard core temperature measurement site (P = .013, ϕ = .49, medium ES). Temperate (57% [22% hot]) CLIMATE dwellers ranked active HA effectiveness higher (P < .001, r = .30, medium ES). Practitioners commonly identified athletes' preference (48%), accessibility, and cost (both 47%) as barriers to HA. Increasing carbohydrate intake when training in the heat was more likely recommended by practitioners (49%) than adopted by athletes (26%; P = .006, 95% CI, 0.1%-1%). Practitioners (56% [28% athletes]) were more likely to plan athletes' daily fluid strategies, adopting a preplanned approach (P = .001; 95% CI, 0.1%-1%). Practitioners, and to a greater extent athletes, lacked self-reported key HA knowledge (eg,core temperature assessment/monitoring methods) yet demonstrated comparatively more appropriate nutritional practices (eg,hydration).

Effects of Methods, Genders, and Interaction to Human Body Temperature Measurement Results Using Tailor-Made Infrared Thermometer and Application Program

The 16-temperature measurement site method is holistic but inefficient. This study compared 8 to 16 temperature measurement site methods on seven married couples. The data gathering was obtained using our infrared thermometer, while the data processing was carried out utilizing Two Way ANOVA with Repetition inserted in our developed application program. Unlike the thermometer in general, our thermometer can equally measure the ear canal and forehead temperature equally. Our made application software was used and validated. The result shows no significant difference between 16 and 8 temperature measurement site methods (F method 0.05 < 4.26). There was no significant difference between male and female temperatures (F gender 1.46 < 4.26), and there was no significant interaction between the method and gender (F interaction 1.51 < 4.26). Male and female temperatures, in general, were almost similar, around 0.57 %, but there was a tendency that they were different in detail. The front head (face), lower part arm, hand, thigh, calf, and feet temperatures for men were slightly higher than for women, while the trunk, upper part arm, and back neck temperatures were slightly higher than men's. Based on these findings, eight temperature measurement site methods can replace the 16-temperature measurement site method. A further study should be carried out to obtain the simplest temperature measurement site but with a significant level of accuracy as the 16-temperature measurement site method. Detail differences between male and female temperatures should also be further investigated.

Reliability of Non-Contact Infrared Thermometers for Fever Screening Under COVID-19.

PurposeFever is one of the most typical clinical symptoms of coronavirus disease 2019 (COVID-19), and non-contact infrared thermometers (NCITs) are commonly used to screen for fever. However, there is a lack of authoritative data to define a “fever” when an NCIT is used and previous studies have shown that NCIT readings fluctuate widely depending on ambient temperatures and the body surface site screened. The aim of this study was to establish cut-off points for normal temperatures of different body sites (neck, forehead, temples, and wrist) and investigate the accuracy of NCITs at various ambient temperatures to improve the standardization and accuracy of fever screening.Patients and MethodsA prospective investigation was conducted among 904 participants in the outpatient and emergency departments of Chengdu Women’s and Children’s Central Hospital. Body temperature was measured using NCITs and mercury axillary thermometers. A receiver operating characteristic curve was used to determine the accuracy of body temperature detection at the four body surface sites. Data on participant characteristics were also collected.ResultsAmong the four surface sites, the neck temperature detection group had the highest accuracy. When the neck temperature was 37.35°C as the optimum fever diagnostic threshold, the sensitivity was 0.866. The optimum fever diagnostic thresholds for forehead, temporal, and wrist temperature were 36.65°C, 36.65°C, and 36.75°C, respectively. Moreover, triple neck temperature detection had the highest sensitivity, up to 0.998, whereas the sensitivity of triple wrist temperature detections was 0.949. Notably, the accuracy of NCITs significantly reduced when the temperature was lower than 18°C.ConclusionNeck temperature had the highest accuracy among the four NCIT temperature measurement sites, with an optimum fever diagnostic threshold of 37.35°C. Considering the findings reported in our study, we recommend triple neck temperature detection with NCITs as the fever screening standard for COVID-19.

Reliability of different body temperature measurement sites during normothermic cardiac surgery.

Patients undergoing cardiac surgery can experience significant thermal changes during the perioperative period and, for that reason, it is essential to monitor temperatures with adequate accuracy and precision during cardiopulmonary bypass (CPB). The primary aim of the current study was to measure the discrepancies between temperatures at different body sites during normothermic or mild hypothermic CPB. 48 patients undergoing cardiac surgery participated in our study. Simultaneous temperatures were measured at nasopharynx, pulmonary artery, arterial outlet, venous inlet, forehead using a heat flux sensor, and urinary bladder at 5-min intervals throughout surgery. The Bland-Altman plot for repeated measures was used to assess concordance between methods. The duration of surgery was 360min (interquartile range (IQR) 300-412), while the median cross-clamp time was 135min (IQR 101-169). During the CPB time, the average difference between arterial outlet and nasopharyngeal temperature was -0.16°C (95% limits of agreement of ±0.93). The bias between arterial outlet and the venous inflow was 0.16°C and the 95% limits of agreement were -0.63 to 0.95°C. The Bland-Altman analysis showed an average difference between oxigenator arterial outlet and bladder probe of -0.62 (95% limits of agreement of ±1.3). The average difference between arterial outlet and Tcore™ temperatures was 0.08°C (95% limits of agreement of ±1.46). 25 patients (52.08%) presented nasopharyngeal temperatures higher than 37°C in the post-CPB period, but none of them exceeded 38°C. Perfusionists should be cautious when using the nasopharyngeal site as the only surrogate of brain temperature, even in normothermic cardiac surgery because the precision of measurements is not entirely adequate.

A Study of Flow Analysis Within a Tractor Cabin with the Goal of Determining the Best Vent Location and Glazing

This study aims to improve the thermal comfort inside a tractor cabin by determining the position of the air conditioner vent location. This is obtained by maintaining the cold air flow inside the cabin by means of the air conditioning vents and proper HVAC systems. The concept of glazing on windows with different materials was also used to improve the thermal comfort of the tractor cabin by reducing the thermal conductivity. Variations in thermal comfort were tested by creating a 3D model of the tractor cabin with different vent locations as per the model of actual tractor cabin with vent locations as follows, dashboard and side pillars. To evaluate the thermal comfort, the anticipated mean vote (PMV) and expected percentage of unsatisfied were utilized, and the temperature, air velocity, and humidity for calculating PMV were simulated. The temperature and PMV measurement sites were chosen based on the SAE J1503 temperature measuring positions. Using suitable data, CFD simulations were performed on commercial simulation software (STAR-CCM+). Based on the result of the analysis, it was observed that maximum thermal comfort was obtained by placing the air conditioner vent on the dashboard which helped in cooling the tractor cabin in less time than the other vent locations. Considering the correct air conditioner vent location together with the spectral solar radiation effect, the average cabin temperature was, which waslower than other vent locations. When exposed to hot temperature conditions, a vehicle's structure can absorb a large quantity of heat. 50-70 percent of this heat passes through the glazing and boosts the internal cabin air temperature as well as the temperature of the interior trim surfaces. When driving away, the air conditioning system must be capable of quickly eliminating this heat, allowing the occupants to return to a comfortable state in a reasonable amount of time. (124). We achieved optimum comfort and a desirable temperature range, we improved working conditions of the operator in a tractor. By using different glazing material, we aim to study and improve operator’s thermal comfort. A 3D based computational fluid dynamics (CFD) software will be used to analyze climate in the tractor vehicle cabin.

Core Temperature Measurement-Principles of Correct Measurement, Problems, and Complications.

Core temperature reflects the temperature of the internal organs. Proper temperature measurement is essential to diagnose and treat temperature impairment in patients. However, an accurate approach has yet to be established. Depending on the method used, the obtained values may vary and differ from the actual core temperature. There is an ongoing debate regarding the most appropriate anatomical site for core temperature measurement. Although the measurement of body core temperature through a pulmonary artery catheter is commonly cited as the gold standard, the esophageal temperature measurement appears to be a reasonable and functional alternative in the clinical setting. This article provides an integrative review of invasive and noninvasive body temperature measurements and their relations to core temperature.

Effect of the use of a surgical guide on heat generation during implant placement: A comparative in vitro study

Heat generation is considered a decisive factor in the occurrence of bone necrosis during implant placement, which can happen when the temperature exceeds a threshold of 47°C for 1 min. The use of a surgical guide to aid implant placement has gained popularity in the last few years. Whether it increases the risk of bone necrosis is still debatable. The aim of the present study was to compare heat generation during implant placement with and without the use of a surgical guide. The study sample consisted of 80 measurement sites placed near 40 dental implant sockets, which were prepared on 10 bone-like dental models. These models were divided into 5 models for the conventional method group and 5 models for the surgical guide group. Each model had 4 implant sockets prepared, and then two 1-millimeter-wide holes were drilled <1 mm away from the socket on the opposite sides of the implant socket to be used as temperature measurement sites. The diameter of the drill was standardized to 2.2 mm, and 4 different drill lengths were used (6, 8, 10, and 12 mm). The data was analyzed using the SPSS for Windows software, v. 13.0. A p-value of <0.05 was deemed statistically significant. Significant differences were found in heat generation between the conventional group (41.07°C) and the surgical guide group (42.97°C) (p < 0.05). Significant changes in temperature were recorded after drilling, regardless of the method used (p < 0.05). Moreover, the length of the drill was associated with temperature changes, with longer drills generating more heat (p < 0.05). Within the limitations of this study, the use of a surgical guide resulted in higher temperatures as compared to the conventional method of implant placement. However, the highest recorded temperature was far below the threshold for bone necrosis.

Application of a High-Density Temperature Measurement System for the Management of the Kaohsiung House Project

In Taiwan, the daytime temperature usually exceeds 37 °C in summer, and the increase in air-conditioning usage has led to higher energy demand, which brings a heavy burden to power plants. The Kaohsiung House Project, undertaken by the city government, encourages the installation of greening facilities in buildings, such as photovoltaic (PV) panels on rooftops and vertical gardens on balconies, in order to preserve energy and reduce carbon emissions. In the present study, the urban heat island effect and temperature distribution within the city was examined through the establishment of 16 temperature measurement sites within a 7.5 km × 6 km area. A between-site temperature difference of 2 °C was observed between April and August. Areas with higher temperature are recommended to increase their green space ratio through the project. Moreover, relocating PV panels in low-temperature areas increased the overall generation efficiency by 0.8%. Through the analysis of the measured data, this study determined which areas were more appropriate for green space expansion, and which would best serve for green energy generation, all with the aim of improving external environmental comfort and maximizing carbon reduction. Recommendations regarding the implementation of subsequent policies were issued and they provide reference for implementation in other cities.

Comparison of temperature measurements in esophagus and urinary bladder in comatose patients after cardiac arrest undergoing mild therapeutic hypothermia.

Mild therapeutic hypothermia (MTH) is a recommended method of treatment for comatose out-of-hospital cardiac arrest (OHCA) survivors. However, the proper site of temperature measurement in MTH is still not defined. The aim of this study was to compare temperature measurements in the esophagus and urinary bladder in comatose post-OHCA patients treated with MTH. This temperature comparison protocol was a part of a prospective, observational, multicenter cohort study. The study population included 36 unconscious patients after resuscitation for OHCA. The patient's core temperature was independently measured every hour during MTH in the urinary bladder and in the esophagus. The mean temperature was lower in the esophagus (differences during induction phase: 1.04 ± 0.92°C, p < 0.0001; stabilization phase: 0.54 ± 0.39°C, p < 0.0001; rewarming phase: 0.40 ± 0.47°C, p < 0.0001). Nevertheless, a strong correlation between both sites was found (R2 = 0.83, p < 0.001). The decrease in temperature observed in the esophagus during the induction phase was faster when compared with the urinary bladder (1.09 ± 0.71°C/h vs. 0.83 ± 0.41°C/h; p = 0.002). As a consequence, time to reach temperature < 34.0°C was longer when temperature was measured in the urinary bladder (the difference between medians of the time 1.0 [0-1.5] h, p < 0.001). Urinary bladder temperature measurements may lag behind temperature changes measured in the esophagus. Monitoring temperature simultaneously in the esophagus and in the urinary bladder is an accessible and reliable combination, although esophageal measurements seem to better reflect the dynamics of temperature changes, thus it seems to be more appropriate for MTH control. ClinicalTrials.gov Identifier: NCT02611934.

Assessment of preferable site for temperature measurement using non contact infra-red temperature among pediatric patients.

Accurate temperature measurement with little or no discomfort that is safe, without risk of hospital-acquired infections or perforations, is the preferred choice of medical professionals in pediatric settings. The objective was to discover the preferable site for body temperature measurement using non-contact infra-red thermometer (NCIT) among pediatric patients. NCIT measurement at mid forehead (F), right temporal region (T), right side of neck- over-carotid artery area (N), jugular notch (J), sternum (S), umbilical region and sublingual region (U) were compared with digital axillary temperature (DAT) in a single attempt in 500 patients, aged between 2 to 5 years with fever. Data was analyzed using Pearson's correlation, paired T-test and Bland-Altman plot to assess the correlation and agreement between the DAT and NCIT sites. The mean temperature of NCIT-T (38.42 ± 0.64 °C) was more agreeable with DAT (38.42 ± 0.63 °C) compared to other body sites. The minimum mean bias of -0.00480 °C was noted for NCIT-F with 95% CI of -0.164-0.15; however, NCIT-F revealed many outliers as compared to NCIT-J. A strong positive correlation existed between DAT and NCIT sites (r value: 0.99-0.98). However, significant difference was found between DAT and NCIT-N, NCIT-F and NCIT-U (p value < 0.0001). NCIT-J is the most preferable choice for measuring body temperature and can be interchanged with DAT. It will help to deliver fast results with enhanced patient comfort due to its non-invasive nature.

Development of a Shallow-Depth Soil Temperature Estimation Model Based on Air Temperatures and Soil Water Contents in a Permafrost Area

A model for predicting shallow depth soil temperatures is important and effective to assess the changes in soil conditions related to global climate change and local disturbances. Shallow-depth soil temperature estimation model in cold region in Alaska is developed based on thermal response using air temperature and shallow-depth soil water content during active layer development period of 160 days from May to October. Among the seven soil temperature measurement sites, data from four sites were used for model development, and the remaining three sites were used for model validation. Near the middle of the seven measurement sites, air temperature is monitored at one location. The proposed model implemented concepts of thermal response and cumulative temperature. Temperatures and soil water contents were measured using automated remote sensing technology. Consequently, it was confirmed that the developed model enables fast and accurate assessment of shallow-depth soil temperature during active soil layer development period.

Managing accidental hypothermia: a UK-wide survey of prehospital and search and rescue providers

AimThe management of hypothermic casualties is a challenge faced by all prehospital and search and rescue (SAR) teams. It is not known how the practice of these diverse teams compare....
