Shoulder Sling

Abstract Background The effect of postoperative shoulder sling compliance on surgical outcomes is unknown. The goal was to determine an accurate method to measure sling compliance. We compared volunteer recorded sling wear time with temperature-based sensors to monitor sling compliance. Methods Data loggers sutured at three locations measured heat generated in 15-minute intervals. Slings wearers logged sling wear to accurately cross-reference with temperature sensors. Secondary experiments analyzed whether surrounding ambient temperature can be discerned from actual sling wear. We created an algorithm to describe actual sling wear time as a function of heat recorded and calculated percent wear accuracy. Results The modified sling was worn for 172 h. The algorithm modeled sling on/off times by analyzing cutoff temperatures. Diagnostic accuracy was >99 % for the three locations, with no statistically significant differences among them. Compared with sling wear, ambient temperature took longer to reach critical temperature values determined by the algorithm, helping distinguish compliance from false positives. Conclusions The described algorithm can effectively quantify shoulder sling wear time based on heat-generated sensor readings. False positives from ambient temperature are minimal. This measurement method could be used to study the relationship between postoperative sling use and functional outcomes after shoulder surgery.

Abstract Background The effect of ambient temperature on allergic rhinitis (AR) remains unclear. Accordingly, this study aimed to explore the relationship between ambient temperature and the risk of AR outpatients in Xinxiang, China. Method Daily data of outpatients for AR, meteorological conditions, and ambient air pollution in Xinxiang, China were collected from 2015 to 2018. The lag-exposure-response relationship between daily mean temperature and the number of hospital outpatient visits for AR was analyzed by distributed lag non-linear model (DLNM). Humidity, long-time trends, day of the week, public holidays, and air pollutants including sulfur dioxide (SO2), and nitrogen dioxide (NO2) were controlled as covariates simultaneously. Results A total of 14,965 AR outpatient records were collected. The relationship between ambient temperature and AR outpatients was generally M-shaped. There was a higher risk of AR outpatient when the temperature was 1.6–9.3 °C, at a lag of 0–7 days. Additionally, the positive association became significant when the temperature rose to 23.5–28.5 °C, at lag 0–3 days. The effects were strongest at the 25th (7 °C) percentile, at lag of 0–7 days (RR: 1.32, 95% confidence intervals (CI): 1.05–1.67), and at the 75th (25 °C) percentile at a lag of 0–3 days (RR: 1.15, 95% CI: 1.02–1.29), respectively. Furthermore, men were more sensitive to temperature changes than women, and the younger groups appeared to be more influenced. Conclusions Both mild cold and mild hot temperatures may significantly increase the risk of AR outpatients in Xinxiang, China. These findings could have important public health implications for the occurrence and prevention of AR.

AbstractPreclinical models propose that increased hippocampal activity drives subcortical dopaminergic dysfunction and leads to psychosis-like symptoms and behaviors. Here, we used multimodal neuroimaging to examine the relationship between hippocampal regional cerebral blood flow (rCBF) and striatal dopamine synthesis capacity in people at clinical high risk (CHR) for psychosis and investigated its association with subsequent clinical and functional outcomes. Ninety-five participants (67 CHR and 28 healthy controls) underwent arterial spin labeling MRI and 18F-DOPA PET imaging at baseline. CHR participants were followed up for a median of 15 months to determine functional outcomes with the global assessment of function (GAF) scale and clinical outcomes using the comprehensive assessment of at-risk mental states (CAARMS). CHR participants with poor functional outcomes (follow-up GAF < 65, n = 25) showed higher rCBF in the right hippocampus compared to CHRs with good functional outcomes (GAF ≥ 65, n = 25) (pfwe = 0.026). The relationship between rCBF in this right hippocampal region and striatal dopamine synthesis capacity was also significantly different between groups (pfwe = 0.035); the association was negative in CHR with poor outcomes (pfwe = 0.012), but non-significant in CHR with good outcomes. Furthermore, the correlation between right hippocampal rCBF and striatal dopamine function predicted a longitudinal increase in the severity of positive psychotic symptoms within the total CHR group (p = 0.041). There were no differences in rCBF, dopamine, or their associations in the total CHR group relative to controls. These findings indicate that altered interactions between the hippocampus and the subcortical dopamine system are implicated in the pathophysiology of adverse outcomes in the CHR state.

Abstract Orthosis-wearing compliance is considered to be an important factor in the outcome of orthotic treatment for idiopathic scoliosis (Rowe, et al. 1997; Katz, et al. 1997). However, at the present time a reliable and objective method of measuring orthosis-wearing time is lacking. Current estimates are based on self-reported compliance and estimated wear and tear of the orthosis itself. Availability of an accurate and reliable technique to measure how long a patient wears a prescribed spinal orthosis will allow clinicians to objectively study the relationship between patient compliance and outcome of orthotic treatment, and arrive at rational guidelines for prescribing orthosis wearing hours. The purpose of this study was to develop an accurate and reliable method to objectively measure spinal orthosis-wearing time.

Background: Previous research has illustrated how leukocytosis after acute ischemic stoke (AIS) is related to poor functional outcome. A main predictor of poor functional outcome is neurodeterioration (ND). We sought to explore the relationship between leukocytosis and time to ND to identify a risk factor for a process that predicts poor functional outcome. Methods: Patients admitted to our stroke center (07/08-06/12) were retrospectively assessed. Leukocytosis was defined as WBC >11,000, ND was characterized as ≥ 2 point increase in NIHSS scale and poor functional outcome was classified as modified Rankin Scale (mRS) of 3-6. Patients were grouped into 2 categories: (1) the leukocytosis group- those who developed leukocytosis ≥24 hours after admission and those who presented with leukocytosis and remained at 24 hours and, (2) the non-leukocytosis group- those that did not have leukocytosis and those where the leukocytosis resolved within 24 hours of admission. Results: A cohort of AIS patients (N=476) with median age 64 years, 43% female and 69% Black were assessed. Of the patients with ND (27%), median time to ND was 43 hours. In the leukocytosis group (N=84), 42 (50.6%) of them developed ND. In the non-leukocytosis group (N=312), 75 (24.5%) developed ND. Leukocytosis within 24 hours of admission is predictive of earlier time to ND (p<0.0001; Figure 1). Adjusting for age, stroke severity, glucose, tPA and infection, the leukocytosis group had a 2 times greater risk for developing ND (HR 2.49, 95%CI 1.61-3.84, p<0.0001). Conclusion: Having leukocytosis persist from admission to 24 hours or developing leukocytosis within 24 hours of admission is a significant predictor of early ND, which often results in poor functional outcome. Identifying such a predictor can enable physicians to identify those at risk for ND and subsequent poor functional outcomes. Future studies are needed to identify if interventions targeting leukocytosis may improve outcome after stroke.

Abstract Introduction We examined the relationship between depression and anxiety, language, and functional outcomes in persons with traumatic brain injury (TBI). Methods The sample consisted of 48 acute TBI (ATBI: 23 Spanish-English Bilinguals; 25 English monolinguals), 30 chronic TBI (CTBI: 17 Spanish English Bilinguals; 12 English monolinguals), and 47 healthy comparison (HC: 29 Spanish-English Bilinguals; 18 English monolinguals) participants. The Hospital Anxiety and Depression Scale was used to measure depression (HADS-D) and anxiety (HADS-A). The Mayo Portland Adaptability Inventory-4 (MPAI-4) was used to measure functional outcomes (ability, adjustment, participation). Results An ANCOVA, controlling for age, revealed the ATBI group reported lower anxiety levels compared to the CTBI group, p = 0.034 np2 = 0.06. HC participants demonstrated significantly higher functional ability compared to both TBI groups, p &lt; 0.05, np2 = 0.08–0.19. The ATBI group demonstrated worse participation scores compared to the CTBI and HC groups, p = 0.001, np2 = 0.11. Pearson correlations revealed mood was related to functional status in ATBI monolinguals (HADS-A: r = 0.29–0.64; HADS-D, r = 0.49–0.62). Monolingual participants with ATBI demonstrated correlations between depressive symptoms and functional adjustment (r = 0.57, p = 0.005) and ability (r = 0.44, p = 0.034). For monolinguals with CTBI, HADS-A correlated with functional outcomes, r = 0.60–0.66, p &lt; 0.05. For bilinguals with CTBI, functional outcomes correlated with HADS-A, r = 0.53–0.66, p &lt; 0.05, and HADS-D, r = 0.54–0.66, p &lt; 0.05. For HC monolinguals, functional outcomes correlated with HADS-A, r = 0.53–0.70, p &lt; 0.05, and HADS-D, r = 0.50–0.72, p &lt; 0.05. Finally, for HC bilinguals, functional outcomes correlated with HADS-A, r = 0.59–0.68, p &lt; 0.05. Conclusion Our results suggest that a relationship between anxiety and depressive symptoms is related more to functional outcomes in monolingual TBI survivors compared to bilingual TBI survivors.

In the mammalian visual system, early stages of visual form processing begin with orientation-selective neurons in primary visual cortex (V1). In many species (including humans, monkeys, tree shrews, cats, and ferrets), these neurons are organized in a beautifully arrayed pinwheel-like orientation columns, which shift in orientation preference across V1. However, to date, the relationship of orientation architecture to the encoding of multiple elemental aspects of visual contours is still unknown. Here, using a novel, highly accurate method of targeting electrode position, we report for the first time the presence of three subdomains within single orientation domains. We suggest that these zones subserve computation of distinct aspects of visual contours and propose a novel tripartite pinwheel-centered view of an orientation hypercolumn.

Thermal factors not only affect the thermal comfort sensation of occupants, but also affect their arousal level, productivity, and health. Therefore, it is necessary to control thermal factors appropriately. In this study, we aim to design a thermal environment that improves both the arousal level and thermal comfort of the occupants. To this end, we investigated the relationships between the physiological indices, subjective evaluation values, and task performance under several conditions of changes in the indoor ambient temperature. In particular, we asked subjects to perform a mathematical task and subjective evaluation related to their thermal comfort sensation and drowsiness levels. Simultaneously, we measured their physiological parameters, such as skin temperature, respiration rate, electroencephalography, and electrocardiography, continuously. We investigated the relationship between the comfort sensation and drowsiness level of occupants, and the physiological indices. From the results, it was confirmed that changes in the indoor ambient temperature can improve both the thermal comfort and the arousal levels of occupants. Moreover, we proposed the evaluation indices of the thermal comfort and the drowsiness level of occupants using physiological indices.
