Objective
To determine whether a powered ankle-foot orthosis (AFO) that provides dorsiflexor and plantar flexor assistance at the ankle can improve walking endurance of persons with multiple sclerosis (MS).Design
Short-term intervention.Setting
University research laboratory.Participants
Participants (N=16) with a neurologist-confirmed diagnosis of MS and daily use of a prescribed custom unilateral passive AFO.Interventions
Three 6-minute walk tests (6MWTs), 1 per footwear condition: shoes (no AFO), prescribed passive AFO, and portable powered AFO (PPAFO). Assistive devices were worn on the impaired limb.Main Outcome Measures
Distance walked and metabolic cost of transport were recorded during each 6MWT and compared between footwear conditions.Results
Each participant completed all three 6MWTs within the experimental design. PPAFO use resulted in a shorter 6MWT distance than did a passive AFO or shoe use. No differences were observed in metabolic cost of transport between footwear conditions.Conclusions
The current embodiment of this PPAFO did not improve endurance walking performance during the 6MWT in a sample of participants with gait impairment due to MS. Further research is required to determine whether expanded training or modified design of this powered orthosis can be effective in improving endurance walking performance in persons with gait impairment due to MS. 相似文献992.

Purpose
In the placebo-controlled Phase III TELESTAR (Telotristat Etiprate for Somatostatin Analogue Not Adequately Controlled Carcinoid Syndrome) trial, the oral tryptophan hydroxylase inhibitor telotristat ethyl significantly reduced bowel movement (BM) frequency during a 12-week, double-blind treatment period in 135 patients with metastatic neuroendocrine tumors with carcinoid syndrome and ≥4 BMs per day. Patients (mean [SD] age, 63.5 [8.9] years; mean [SD] body mass index, 24.9 [4.9] kg/m2) received placebo, telotristat ethyl 250 mg, or telotristat ethyl 500 mg 3 times per day (TID) in addition to somatostatin analogue therapy. Weight loss is associated with uncontrolled carcinoid syndrome and may be associated with reduced survival.Methods
Assessment of the occurrence of weight change ≥3% at week 12 was prespecified in the statistical analysis plan.Findings
In 120 patients with weight data available, weight gain ≥3% was observed in 2 of 39 patients (5.1%) taking placebo TID, 7 of 41 (17.1%) taking telotristat ethyl 250 mg TID, and 13 of 40 (32.5%) taking telotristat ethyl 500 mg TID (P = 0.0017) at week 12. Weight loss ≥3% was observed in 5 of 39 patients (12.8%) taking placebo TID, 4 of 41 (9.8%) taking telotristat ethyl 250 mg TID, and 6 of 40 (15.0%) taking telotristat ethyl 500 mg TID (P = 0.77). Biochemical and metabolic parameters of serum albumin and cholesterol significantly increased (P = 0.02 and P = 0.001, respectively) in patients gaining weight and decreased in patients who lost weight, suggesting an improvement in overall nutritional status.Implications
Up to 32.5% of patients treated with telotristat ethyl experienced significant, dose-dependent weight gain, associated with reduced diarrhea severity and improved biochemical and metabolic parameters. Improved nutritional status could be an additional aspect of telotristat ethyl efficacy among patients with functioning metastatic neuroendocrine tumors.

Bedside ultrasound is often used as a part of the evaluation of patients who are critically ill. The McConnell sign is an important echocardiographic finding in some critically ill patients with pulmonary embolism and an acute right ventricular infarct. We present 3 critically ill patients with confirmed acute chest syndrome who showed the McConnell sign on echocardiography. In patients with sickle cell disease presenting with chest pain and shortness of breath, the presence of the McConnell sign does not narrow the differential diagnosis between pulmonary embolism, an acute right ventricular infarct, and acute chest syndrome. 相似文献

Introduction
Previous work has suggested that Emergency Department rotational patient assignment (a system in which patients are algorithmically assigned to physicians) is associated with immediate (first-year) improvements in operational metrics. We sought to determine if these improvements persisted over a longer follow-up period.Methods
Single-site, retrospective analysis focused on years 2–4 post-implementation (follow-up) of a rotational patient assignment system. We compared operational data for these years with previously published data from the last year of physician self-assignment and the first year of rotational patient assignment. We report data for patient characteristics, departmental characteristics and facility characteristics, as well as outcomes of length of stay (LOS), arrival to provider time (APT), and rate of patients who left before being seen (LBBS).Results
There were 140,673 patient visits during the five year period; 138,501 (98.7%) were eligible for analysis. LOS, APT, and LBBS during follow-up remained improved vs. physician self-assignment, with improvements similar to those noted in the first year of implementation. Compared with the last year of physician self-assignment, approximate yearly average improvements during follow-up were a decrease in median LOS of 18 min (8% improvement), a decrease in median APT of 21 min (54% improvement), and a decrease in LBBS of 0.69% (72% improvement).Conclusion
In a single facility study, rotational patient assignment was associated with sustained operational improvements several years after implementation. These findings provide further evidence that rotational patient assignment is a viable strategy in front-end process redesign. 相似文献997.

Objective
To evaluate the effectiveness and potential benefits of topical tranexamic acid (TXA) in the management of acute epistaxis.Methods
Retrospective review was performed among all patients presenting to the institution's emergency department (ED) with epistaxis between September 2014 and August 2016. Patients achieving hemostasis with standard of care agents, such as oxymetazoline, lidocaine, or epinephrine were excluded. The primary outcome was the ED length of stay (LOS). Secondary outcomes included the incidence of hospital admission, otolaryngologist consultation, nasal packing, prophylactic antibiotic use, and ED visit for rebleeding within seven days of treatment.Results
Among 122 patients, 30 received topical TXA (500 mg injectable solution soaked onto packing material and applied to the affected nostril) and 92 were managed with standard care. Nearly half (46.7%) of TXA-treated subjects received TXA either alone or in combination with standard of care agents as their initial treatment strategy. No significant difference was observed in the ED LOS (272 vs 232 min in TXA and standard care arms, respectively, p = 0.26). However, TXA was associated with a significant reduction in otolaryngologist consults (30.0% vs 65.2%, p = 0.002) and nasal packing (16.7% vs 23.9%, p = 0.003).Conclusions
This investigation did not demonstrate a significant difference in ED LOS among patients with acute epistaxis treated with topical TXA or standard care. However, this data does add to existing evidence that TXA may be associated with a reduction in resource utilization, suggesting it may provide more effective bleeding control. Overall, more data is needed to confirm the potential benefits of this practice. 相似文献998.

Introduction
Beaches are a popular destination for recreation activities. Surf zone injuries (SZI) can occur resulting from a variety of in-water activities. Little is known regarding the sustained injury types, or demographics of injured persons and activities leading to injuries.Methods
This study examines the distribution of SZI types, activities and populations occurring on Delaware Beaches as recorded by a local level III trauma center (Department of Emergency Medicine at Beebe Healthcare in Lewes, Delaware).Results
There were 2021 injuries over the eight study years (2010–2017). The relative demographics of the injured population are similar despite fluctuating injury totals (mean [SD], 253.1 [104.4]). Non-locals (n = 1757) were 6.7 times more likely to be injured as their local (n = 264) counterparts (RR, 2.62; 95% CI, 2.08–3.31). Males (n = 1258) were 1.7 times more likely to be injured than their female (n = 763) counterparts (RR, 1.29; 95% CI, 1.21–1.37). Serious injuries, defined as patients requiring admission to a trauma service, represented 9.1% (n = 184) of injuries. Fatal SZI (n = 6) were categorized as serious injuries. Wading (50.1%) was found to be the dominant activity associated with injury followed by body surfing (18.4%), and body boarding (13.3%).Conclusion
To the authors' knowledge, this study is one of the first to investigate long-term trends in SZI data, injury activity, and demographics. Better understanding of the characteristics of injuries will allow for improved awareness techniques, targeted at populations with higher injury rates. 相似文献1000.
