This prospective, randomized study compared postoperative pain control with use of a continuous temperature-controlled cryotherapy system versus a traditional ice therapy regimen following outpatient knee arthroscopy. Patients with unilateral knee pathology scheduled for outpatient arthroscopic surgery were included. Patients with major ligament reconstructions were excluded. A specific cold therapy regimen was begun postoperatively and continued for 2 weeks as adjunctive management of postoperative pain. Preoperative and postoperative pain intensity, pain type, functionality, and sleep quality were assessed. Patients were randomly assigned to either an ice or a continuous cryotherapy group. Follow-up questionnaires were completed on 5 postoperative days. Data were analyzed using a chi-square test with a level of significance at P < 0.05. Fifty-three patients completed the study. Pain intensity was similar between groups throughout the course of the study. Among patients who reported experiencing night pain, 36% of those in the continuous cryotherapy group were able to sleep soundly with minimal awakening through postoperative day 2 versus 5.9% among the ice therapy group (P = 0.04). No significant differences existed between groups regarding functional ability, and no differences were noted on other follow-up days. These findings support use of continuous temperature-controlled cold therapy devices for nighttime pain control and improved quality of life in the early period following routine knee arthroscopy.

To reduce opioid-related morbidity and mortality, local coalitions on substance use prevention in Kern County, California, have sought to increase equitable engagement and reengagement with harm reduction supplies, including naloxone. Through a community-academic partnership and funding from the local managed health care plan in Kern County, we ordered, stocked, and monitored a temperature-controlled outdoor harm reduction vending machine (HRVM) in Bakersfield, California. We outlined the necessary steps for successful procurement and implementation of community-based HRVMs.

The local sweat rate (LSR) response to intradermal electrical stimulation generates a sigmodal stimulus-response curve with a peak sweat rate generated during a 30-s period of continuous stimuli at a frequency of 16-32 Hz. However, the in vivo firing pattern of the sudomotor nerve resembles more of a bursting pattern. We tested the hypothesis that a bursting pattern during intradermal electrical stimulation would result in a greater sweating response than the regular continuous stimulus pattern.

The influence of oxidation state and crystalline structure on the dissolution mechanisms of both pure iron oxides and combusted iron particles in aqueous oxalic acid (0.5 mol/l) at 60 °C was systematically investigated. Dissolution experiments were carried out in a temperature-controlled, continuous-flow capillary reactor, allowing for the removal of reaction products and thereby suppressing the autocatalytic reaction mechanism.

We investigated the biogenic volatile organic compound (BVOC) emission rates and composition of Cupressaceae species and how the emissions change in response to moderate warming and more severe heat stress. A total of 8 species from 7 distinct Cupressaceae genera were targeted in this study and exposed to laboratory-simulated heatwaves. Each plant was enclosed in a temperature-controlled glass chamber and allowed to equilibrate at 30 °C for 24 h.
