Environments and situations as correlates of eating and drinking among women living with obesity and urban poverty.

Objective: One path to improving weight management may be to lessen the self-control burden of physical activity and healthier food choices. Opportunities to lessen the self-control burden might be uncovered by assessing the spatiotemporal experiences of individuals in daily context. This report aims to describe the time, place, and social context of eating and drinking and 6-month weight change among 209 midlife women (n = 113 African-American) with obesity receiving safety-net primary care. Methods: Participants completed baseline and 6-month weight measures, observations and interviews regarding obesogenic cues in the home environment, and up to 12 ecological momentary assessments (EMA) per day for 30 days inquiring about location, social context, and eating and drinking. Results: Home was the most common location (62%) at times of EMA notifications. Participants reported "yes" to eating or drinking at the time of nearly one in three (31.1% ± 13.2%) EMA notifications. Regarding social situations, being alone was significantly associated with less frequent eating and drinking (OR = 0.75) unless at work in which case being alone was significantly associated with a greater frequency of eating or drinking (OR = 1.43). At work, eating was most common late at night, whereas at home eating was most frequent in the afternoon and evening hours. However, eating and drinking frequency was not associated with 6-month weight change. Conclusions: Home and work locations, time of day, and whether alone may be important dimensions to consider in the pursuit of more effective weight loss interventions. Opportunities to personalize weight management interventions, whether digital or human, and lessen in-the-moment self-control burden might lie in identifying times and locations most associated with caloric consumption.Clinical trial registration: NCT03083964 in clinicaltrials.gov.

Effect of different Kinesio tape tensions on experimentally-induced thermal and muscle pain in healthy adults.

Athletes and rehabilitation specialists have used Kinesio tape (KT) to help alleviate pain symptoms. Currently, no clear mechanism exists as to why pain is relieved with the use of KT and whether the pain relieving effect is simply a placebo effect. Additionally, the most effective taping parameters (tension of tape) for pain reduction remain unknown. We used quantitative sensory testing to address these key gaps in the KT and pain literature. Using a repeated-measures laboratory design, we examined whether KT applied at different tensions reduces experimentally-induced pain compared to a no tape condition and KT with minimal tension. Heat pain thresholds (HPT's), pressure pain thresholds (PPT's), and pressure pain suprathreshold (PPS: 125% of PPT) tests were administered to the forearm prior to and during KT and no tape conditions. Tape was applied to the ventral forearm at 25% of max tension, 75% of max tension, and no tension (placebo). Repeated measures ANOVA's evaluated the pain outcomes between conditions and across time. KT had no significant effect on PPT's and HPT's (p's >0.05). The ANOVA on PPS revealed that KT applied at 25% of tension significantly reduced pain ratings from the pretest (M = 34.4, SE = 5.5) to post-test 1 (M = 30.3, SE = 4.7) and post-test 2 (M = 30.4, SE = 4.7). No other conditions significantly reduced suprathreshold pressure pain. However, pain ratings at posttest-1 during the no-tape condition (M = 36.4, SE = 5.3) were significantly greater than pain ratings during post-test 1 and post-test 2 of all three tape conditions. In conclusion, the current study revealed that KT applied at low tension is the optimal tension to reduce pressure-evoked muscle pain. Additionally, the results suggested that KT applied at low, high, or no tension may acutely prevent increased muscle sensitivity with repeated pressure stimulation.

The Decline of Endogenous Pain Modulation With Aging: A Meta-Analysis of Temporal Summation and Conditioned Pain Modulation.

The purpose of this article was to examine age-related changes in conditioned pain modulation (CPM) and temporal summation (TS) of pain using meta-analytic techniques. Five electronic databases were searched for studies, which compared measures of CPM and TS among healthy, chronic pain-free younger, middle-aged, and older adults. Eleven studies were included in the final review for TS and 11 studies were included in the review of CPM. The results suggested a moderate magnitude of difference in TS among younger and middle-aged/older adults, with the older cohorts exhibiting enhanced TS of pain. Considerable variability existed in the magnitude of the effect sizes, which was likely due to the different experimental methodologies used across studies (ie, interstimulus interval, stimulus type, and body location). In regards to CPM, the data revealed a large magnitude of difference between younger and older adults, with younger adults exhibiting more efficient pain inhibition. Differences in CPM between middle-aged and older adults were minimal. The magnitude of pain inhibition during CPM in older adults may depend on the use of concurrent versus nonconcurrent protocols. In summary, the data provided strong quantitative evidence of a general age-related decline in endogenous pain modulatory function as measured by TS and CPM. PERSPECTIVE: This review compared CPM and TS of pain among younger, middle-aged, and older adults. These findings enhance our understanding of the decline in endogenous pain modulatory function associated with normal aging.

Bilateral hearing loss following a retrobulbar block.

PURPOSE: Regional anesthesia is the most commonly used ophthalmological anesthetic technique in Canada and the United States. Brainstem anesthesia is not an uncommon complication of retrobulbar blocks. Anesthesiologists are a prominent element in the ophthalmology suite, in part due to the complications possible with regional anesthesia. This is the first reported case of complete bilateral hearing loss following a retrobulbar block. CLINICAL FEATURES: A 46-yr-old male with type 1 diabetes mellitus presenting for ophthalmological surgery had a retrobulbar block performed by the ophthalmologist. Local anesthetic was injected through a 25 G, 1.5 inch needle, entering the orbit inferiorly on the temporal third of the lower lid. Shortly after the block was completed the patient experienced sudden hearing loss. On examination the hearing loss appeared to be complete and bilateral. The patient was alert and oriented; the remainder of the cranial nerve exam was normal. The patient's hearing loss gradually improved and three hours after the block his hearing had subjectively returned to normal. CONCLUSION: Brainstem anesthesia is not a rare complication of regional anesthesia for ophthalmological surgery. Symptoms include confusion, mental agitation, dizziness, blurred vision or blindness, ophthalmoplegia, deafness, tinnitus, dysphagia, dysarthria, respiratory depression to apnea, and/or limb paralysis. A connection between the subdural and subarachnoid spaces and the optic sheath exists. The effect on the central nervous system depends upon the amount of local anesthetic injected and the area to which it spreads.

Clinical inquiries. How should we follow athletes after a concussion?

Athletes sustaining a concussion should be held from contact activities a minimum of 7 days; they must be asymptomatic and their coordination and neuropsychological tests should have returned to their pre-injury baseline (strength of recommendation [SOR]: B, based on multiple prospective cohort studies). High-risk athletes (eg, those with a history of previous concussion, high-school age or younger, or female) may need to avoid contact even after all these criteria are met (SOR: C, expert opinion).
