Interpersonal distress is associated with sleep and arousal in insomnia and good sleepers

Objective

The interpersonal environment is strongly linked to sleep. However, little is known about interpersonal distress and its association with sleep. We examined the associations among interpersonal distress, objective and subjective sleep in people with and without insomnia.

Methods

Participants in this cross-sectional observational study included men and women with insomnia (n = 28) and good sleeper controls (n = 38). Interpersonal distress was measured with the Inventory of Interpersonal Problems. Sleep parameters included insomnia severity, self-reported presleep arousal, and sleep quality; and polysomnographically-assessed sleep latency (SL), total sleep time (TST), wake after sleep onset (WASO), percent delta (stage 3 + 4 NREM), percent REM, and EEG beta power. Hierarchical linear regression was used to assess the relationship between distress from interpersonal problems and sleep and the extent to which relationships differed among insomnia patients and controls.

Results

More interpersonal distress was associated with more self-reported arousal and higher percentage of REM. More interpersonal distress was associated with greater insomnia severity and more cognitive presleep arousal for individuals with insomnia, but not for controls. Contrary to expectations, interpersonal distress was associated with shorter sleep latency in the insomnia group. Results were attenuated, but still significant, after adjusting for depression symptoms.

Conclusion

Distress from interpersonal problems is associated with greater self-reported arousal and higher percent REM. Individuals with insomnia who report more distress from interpersonal problems have greater insomnia severity and cognitive presleep arousal, perhaps due to rumination. These findings extend our knowledge of the association between interpersonal stressors and sleep. Assessment and consideration of interpersonal distress could provide a novel target for insomnia treatment.     

Low rate of active treatment of patients with hilar cholangiocarcinoma

Introduction

The results of surgical resection and palliative chemotherapy use in hilar cholangiocarcinoma (HC) have been well publicised but the proportion of patients able to undergo these treatments and the comparative outcomes in a population of patients with HC are less well known.

Methods

Patients with HC were identified by review of all patients undergoing percutaneous cholangiography over a nine-year period (2002–2010) in a tertiary facility. The treatment undertaken and outcomes were recorded.

Results

Overall, 68 patients were identified (37 female) with a median age of 70 years. Forty-five (66%) were treated solely by insertion of a metal stent (median survival 4.73 months) and nine (13%) also received palliative chemotherapy (median survival 13.7 months). Persisting jaundice after stent insertion was noted in 18 of 35 patients (51%) tested within one month of death. Fourteen patients (21%) underwent surgical resection (median survival 20.2 months).

Conclusions

Patients undergoing surgical resection had significantly longer survival than those receiving only a palliative stent but not compared with those also receiving palliative chemotherapy, with short-term follow-up. Only a third of patients, however, receive active treatment (surgery or chemotherapy) and improvements in long-term biliary palliation are needed.     

腹膜外切口单层缝合与常规分层缝合法在化脓性或坏疽性阑尾炎术后疗效比较中的系统评价

目的评价腹膜外切口单层缝合与常规分层缝合法在化脓性或坏疽性阑尾炎术后的临床疗效。方法计算机检索Co-chrane Library、PubMed、Embase、SCI、CNKI、CBM、VIP、WANFANG DATA,纳入腹膜外切口单层缝合与常规分层缝合法在化脓性或坏疽性阑尾炎术后疗效比较的随机对照试验,对纳入研究的方法学质量进行评价,用Cochrane协作网提供的RevMan 5.1软件对数据进行统计分析,并对统计结果进行系统评价。结果共纳入6个随机对照试验,共计1 885例患者。Meta分析结果显示:腹膜外切口单层缝合与常规分层缝合法在手术时间[MD=-17.09,95%CI(-19.32,-14.87)],术后切口感染率[RR=0.06,95%CI(0.03,0.12)],7 d内出院率[RR=1.17,95%CI(1.13,1.22)]方面差异均具有统计学意义,但两者在术后疼痛程度(需应用镇痛药物比率)[RR=1.05,95%CI(0.91,1.20)]方面的差异无统计学意义。结论目前研究表明,与常规分层缝合法相比,腹膜外切口单层缝合法能显著缩短化脓性或坏疽性阑尾炎患者的手术时间,降低术后切口感染率,提高7 d内出院率,但本研究纳入的样本量小且质量不高,因此,有必要开展更多高质量、多中心的随机盲法对照试验进一步予以证实其疗效。     

Improvement and Recovery from Eating Disorders: A Patient Perspective

This study presents a patient perspective on improvement and recovery from eating disorders. Forty-eight women recruited from patient organizations and a university eating disorder unit participated in the study. Participants completed standard questionnaires and a qualitative interview. "A wish to change," professional treatment, nonprofessional care, and important persons in the women's lives were identified as important recovery factors. Recovery included improved acceptance of oneself, interpersonal relations, problem solving, and body satisfaction, which was not entirely dependent on symptom absence. The patient perspective concurred with clinical reasoning about recovery.     

Environmental Factors Predictive of No-Show Visits in Radiology: Observations of Three Million Outpatient Imaging Visits Over 16 Years

PurposeTo evaluate the impact of environmental and socioeconomic factors on outpatient cancellations and “no-show visits” (NSVs) in radiology.Materials and MethodsWe conducted a retrospective analysis by collecting environmental factor data related to outpatient radiology visits occurring between 2000 and 2015 at our multihospital academic institution. Appointment attendance records were joined with daily weather observations from the National Oceanic and Atmospheric Administration and estimated median income from the US Census American Community Survey. A multivariate logistic regression model was built to examine relationships between NSV rate and median income, commute distance, maximum daily temperature, and daily snowfall.ResultsThere were 270,574 (8.0%) cancellations and 87,407 (2.6%) NSVs among 3,379,947 scheduled outpatient radiology appointments and 575,206 unique patients from 2000 to 2015. Overall cancellation rates decreased from 14% to 8%, and NSV rates decreased from 6% to 1% as median income increased from $20,000 to $120,000 per year. In a multivariate model, the odds of NSV decreased 10.7% per $10,000 increase in median income (95% confidence interval [CI]: 10.3%-11.1%) and 2.0% per 10°F increase in maximum daily temperature (95% CI: 1.3%-1.6%). The odds of NSV increased 1.4% per 10-mile increase in commute distance (95% CI: 1.3%-1.6%) and 4.5% per 1-inch increase in daily snowfall (95% CI: 3.6%-5.3%). Commute distance was more strongly associated with NSV for those in the two lower tertiles of income than the highest tertile (P < .001).ConclusionEnvironmental factors are strongly associated with patients’ attendance at scheduled outpatient radiology examinations. Modeling of appointment failure risk based on environmental features can help increase the attendance of outpatient radiology appointments.
