Flight Initiation

Flight initiation distance (predator–prey distance when escape begins) increases as predation risk increases. Prey should have longer flight initiation distance when their background, movement, or current posture reduces crypsis. Flight initiation distance of ectotherms may increase at lower body temperature to compensate for slower running speed. However, for cryptic prey, fleeing might increase the probability of being detected. The Round-tailed Horned Lizard ( Phrynosoma modestum Girard, 1852) is eucryptic and resembles small stones. We predicted that flight initiation distance by P. modestum is shorter among stones than on uniform sand. Because movement and upright posture disrupt crypsis, we predicted that flight initiation distance is greater after movement and when standing than when still and lying on the ground. As predicted, flight initiation distances were shorter on a rocky than sandy area, when lying flat than standing, and while immobile than after moving. We measured running speed and flight initiation distance to determine relationships among body temperature, speed, and escape decisions. Running speed and flight initiation distance were reduced at lower body temperature, suggesting that crypsis reinforced by immobility is more advantageous than longer flight initiation distance for cool, slow lizards. The lizards adjusted escape decisions to current effectiveness of crypsis and escape ability.

Introduction: Post-cardiac arrest pyrexia is associated with poor outcomes following successful resuscitation and return of spontaneous circulation (ROSC). Prior studies have used highest recorded temperature and duration of fever as markers for the severity of pyrexic events. The objective of this research was to evaluate the association of body temperature and survival to discharge. We hypothesized that a lower body temperature “dose” in the 8 days post-arrest would be associated with a higher likelihood of survival. Methods: Using consecutive cardiac arrest cases from a single healthcare system with integrated electronic medical record (EMR), we identified cardiac arrest patients with ROSC. Vital signs for these patients, including body temperature, were queried from the EMR and linked to individual records. We included all temperature measures within 8 days of the cardiac arrest event. Patients with fewer than 5 temperature values during the study period were excluded. For each temperature observation the difference between the recorded temperature value and 37 degrees Celsius, the time since the last observation, and the product of these values was calculated. For each patient, the total ‘dose’ was calculated as the sum of these dose products. The resulting measure has units of degree*hours and represents a measure of duration about or below normal. Multiple logistic regression was used to assess the relationship between body temperature dose and survival to discharge, controlling for age and sex. Results: Between 3/2006 and 3/2016, 352 patients were linked to serial body temperature measurements. 58% were male, mean age was 61 ± 16 years, and 52% survived to discharge. The median body temperature dose measure was 28 degree*hours, (IQR: -0.6 - 98, min: -740, max 390). Results from the multiple logistic regression indicated that for every 10 degree*hour increase in patient body temperature, the odds of survival decreased 3.1 percent (OR: 0.969, p = 0.01) when controlling for age and sex. Conclusion: In this study, lower serial body temperature ‘dose’ was associated with increased odds of survival. These findings are consistent with international guidance around the strong avoidance of fever in post-arrest patients.

Purpose: To assess the correlation between admission body temperature and delayed cerebral infarction in elderly patients with ruptured intracranial aneurysm (IA).Methods: Patients with ruptured IA diagnosed between 2012 and 2020 were retrospectively analyzed. Patients were divided into a non-infarction and an infarction group based on the presence of cerebral infarction after treatment. The demographic and clinical information of the patients was gathered. Outcomes at the 3-month follow-up were assessed using the modified Rankin Scale. Correlation between admission body temperature and cerebral infarction was assessed using Spearman's rank correlation coefficient. A receiver operating characteristic (ROC) curve was used to assess the specificity and sensitivity of admission body temperature to predict cerebral infarction.Results: A total of 426 patients (142 men and 284 women) with ruptured IA were enrolled. Elderly patients with cerebral infarction (12.4%) had a lower body temperature at admission (p &lt; 0.001), higher prevalence of hypertension and diabetes (p = 0.051 and p = 0.092, respectively), and higher rate of poor outcomes (p &lt; 0.001). Admission body temperature was independently associated with cerebral infarction (odds ratio [OR] = 5.469, p &lt; 0.001); however, hypertension (OR = 0.542, p = 0.056), diabetes (OR = 0.750, p = 0.465), and aneurysm size (OR = 0.959, p = 0.060) showed no association. An inverse correlation between admission body temperature and the incidence of cerebral infarction was observed (Spearman's r =−0.195, p &lt; 0.001). An admission body temperature of 36.6°C was able to distinguish infarction and non-infarction patients. The area under the ROC curve was 0.669 (specificity, 64.15%; sensitivity, 81.50%; p &lt; 0.001).Conclusions: Lower body temperature at admission (≤36.6°C) is an independent predictor of delayed cerebral infarction in elderly patients who have undergone treatment for ruptured IA. Therefore, it could be a risk factor for adverse outcomes of IA.

Fever is defined as rise in normal body temperature above 98.6°F. Clinical thermometer is a medical instrument for measuring human body temperature. The traditionally used mercury in glass thermometer was replaced by digital thermometer due to mercury toxicity. Non-contact infra-red thermometer is a non-invasive thermometer used for un-cooperative pediatric patients. The objective of this study is to determine the clinical efficiency of non-contact infrared thermometer over axillary digital thermometer and mercury in glass thermometer over a range of body temperature by using paracetamol in febrile patients. This descriptive hospital based cross sectional study was conducted from 5th December 2019 till 23rd August 2020 after ethical approval from Institutional Review Committee of Nepal Medical College and Teaching Hospital. Mercury in glass thermometer, axillary digital thermometer and non-contact infrared thermometer were used to measure body temperature in febrile patient. Body temperature was re-measured one hour after administration of paracetamol. Data was entered and analyzed with statistical package for social sciences version 16. Axillary digital thermometer has high predictability in the upper body temperature range (in febrile state) but its predictability is low in lower body temperature range (our normal body temperature). Non-contact infrared thermometer in comparison with axillary digital thermometer has lower predictability in both upper and lower body temperature range. Clinical efficiency of non-contact infrared thermometer is less than that of axillary digital thermometer and mercury in glass thermometer in febrile patients.
