Screening for Trauma-Related Sleep Disturbance in Women Admitted for Specialized Inpatient Treatment

Abstract

The authors designed a Sleep Disturbance Screening questionnaire to assist clinicians in disentangling trauma-related factors that contribute to sleep disturbance from other common factors, such as depression. They administered the questionnaire to 129 female psychiatric inpatients, most of whom were treated in a specialty program for trauma-related disorders. Confirmatory and exploratory factor analyses distinguished four sleep disturbance scales, two pertaining to sleep disturbance generally (Insomnia, Hypersomnia) and two pertaining to sleep-related fear (Intrusive, Phobic). Correlations of the sleep disturbance scales with the Childhood Trauma Questionnaire (Bernstein et al., 1994), Impact of Event Scale-Revised (Weiss & Marmar, 1997), Dissociative Experiences Scale (Bernstein & Putnam, 1986), Beck Depression Inventory (Beck & Steer, 1993), and selected scales of the Millon Clinical Multiaxial Inventory (MCMI-III; Millon, 1994) show evidence of convergent and discriminant validity for the Sleep Disturbance Screening. The findings point to the potential diagnostic value of screening for trauma-related sleep disturbance, with the Sleep Disturbance Screening providing a small set of key questions that may be used in psychometric form or incorporated into routine diagnostic clinical interviews.     

From the Cover: Gut bacteria facilitate adaptation to crop rotation in the western corn rootworm

Insects are constantly adapting to human-driven landscape changes; however, the roles of their gut microbiota in these processes remain largely unknown. The western corn rootworm (WCR, Diabrotica virgifera virgifera LeConte) (Coleoptera: Chrysomelidae) is a major corn pest that has been controlled via annual rotation between corn (Zea mays) and nonhost soybean (Glycine max) in the United States. This practice selected for a “rotation-resistant” variant (RR-WCR) with reduced ovipositional fidelity to cornfields. When in soybean fields, RR-WCRs also exhibit an elevated tolerance of antiherbivory defenses (i.e., cysteine protease inhibitors) expressed in soybean foliage. Here we show that gut bacterial microbiota is an important factor facilitating this corn specialist’s (WCR''s) physiological adaptation to brief soybean herbivory. Comparisons of gut microbiota between RR- and wild-type WCR (WT-WCR) revealed concomitant shifts in bacterial community structure with host adaptation to soybean diets. Antibiotic suppression of gut bacteria significantly reduced RR-WCR tolerance of soybean herbivory to the level of WT-WCR, whereas WT-WCR were unaffected. Our findings demonstrate that gut bacteria help to facilitate rapid adaptation of insects in managed ecosystems.

Associations between Nighttime Traffic Noise and Sleep: The Finnish Public Sector Study

Background: Associations between traffic noise and sleep problems have been detected in experimental studies, but population-level evidence is scarce.Objectives: We studied the relationship between the levels of nighttime traffic noise and sleep disturbances and identified vulnerable population groups.Methods: Noise levels of nighttime–outdoor traffic were modeled based on the traffic intensities in the cities of Helsinki and Vantaa, Finland. In these cities, 7,019 public sector employees (81% women) responded to postal surveys on sleep and health. We linked modeled outdoor noise levels to the residences of the employees who responded to the postal survey. We used logistic regression models to estimate associations of noise levels with subjectively assessed duration of sleep and symptoms of insomnia (i.e., difficulties falling asleep, waking up frequently during the night, waking up too early in the morning, nonrestorative sleep). We also used stratified models to investigate the possibility of vulnerable subgroups.Results: For the total study population, exposure to levels of nighttime–outside (L_{night, outside}) traffic noise > 55 dB was associated with any insomnia symptom ≥ 2 nights per week [odds ratio (OR) = 1.32; 95% confidence interval (CI): 1.05, 1.65]. Among participants with higher trait anxiety scores, which we hypothesized were a proxy for noise sensitivity, the ORs for any insomnia symptom at exposures to L_{night, outside} traffic noises 50.1–55 dB and > 55 dB versus ≤ 45 dB were 1.34 (95% CI: 1.00, 1.80) and 1.61 (95% CI: 1.07, 2.42), respectively.Conclusions: Nighttime traffic noise levels > 50 dB L_{night, outside} was associated with insomnia symptoms among persons with higher scores for trait anxiety. For the total study population, L_{night, outside} > 55 dB was positively associated with any symptoms.     

Relationship between unhealthy sleep status and dry eye symptoms in a Japanese population: The JPHC-NEXT study

PurposeTo investigate whether and how unhealthy sleep habits (i.e., the frequency of difficulty falling or staying asleep, and the frequency of waking up tired) and the duration of sleep are related to the prevalence of dry eye disease (DED) in a general population.MethodsThis study included a total of 106,282 subjects aged 40–74 years who participated in a baseline survey of the Japan Public Health Center-based Prospective Study for the Next Generation. DED was defined as the presence of clinically diagnosed DED or severe symptoms. Multivariable-adjusted logistic regression models were used to assess the relationships of various components of sleep status with DED.ResultsHigher frequencies of having difficulty falling or staying asleep, and waking up tired were significantly related to increased DED in both sexes (P_trend<0.001). Compared with those with 8 h/day of sleep, shorter sleepers had an increased prevalence of DED in both sexes, although DED was increased among men who slept ≥10 h/day. By comparing participants with the greatest vs. the least difficulty of falling asleep, the multivariable-adjusted odds ratios (95% confidence interval [CI]) were 2.23 (95% CI, 1.99–2.49) for men and 1.91 (95% CI, 1.76–2.07) for women. When analyzed separately, the magnitude of each relationship was stronger with severe DED symptoms than with clinically diagnosed DED.ConclusionsSleep deprivation and poor sleep quality were significantly related to DED in a Japanese population.     

Proton pump inhibitors linked to hypomagnesemia: a systematic review and meta-analysis of observational studies

Abstract

Background: The reported risk of hypomagnesemia in patients with proton pump inhibitor (PPI) use is conflicting. The objective of this meta-analysis was to assess the association between the use of PPIs and the risk of hypomagnesemia. Methods: A literature search of observational studies was performed using MEDLINE, EMBASE and Cochrane Database of Systematic Reviews from inception through September 2014. Studies that reported odd ratios or hazard ratios comparing the risk of hypomagnesemia in patients with PPI use were included. Pooled risk ratios (RRs) and 95% confidence interval (CI) were calculated using a random-effect, generic inverse variance method. Results: Nine observational studies (three cohort studies, five cross-sectional studies and a case-control study) with a total of 109,798 patients were identified and included in the data analysis. The pooled RR of hypomagnesemia in patients with PPI use was 1.43 (95% CI, 1.08–1.88). The association between the use of PPIs and hypomagnesemia remained significant after the sensitivity analysis including only studies with high quality score (Newcastle–Ottawa scale score?≥?8) with a pooled RR of 1.63 (95% CI, 1.14–2.23). Conclusions: Our study demonstrates a statistically significant increased risk of hypomagnesemia in patients with PPI use. The finding of this meta-analysis of observational studies suggests that PPI use is associated with hypomagnesemia and may impact clinical management of patients who are taking PPIs and at risk for hypomagnesemia related cardiovascular events.     

When is nighttime? A description of bedtime in persons with dementia in the nursing home

The purpose of this secondary data analysis was to describe the bedtime patterns of persons with dementia in the nursing home and make recommendations for nursing practice. Nursing staff observed, researcher observed, and actigraph data on bedtimes were compared with nighttime facility routines. Seventy per cent (n = 14) of all participants (n = 20) were in bed before 8:30 pm and 30% (n = 6) of the participants went to bed after 8:30 pm. All participants who went to bed before 8:30 pm (n = 14) took evening medications and 64% (n = 9) were dependent upon nursing care for nighttime activities of daily living (ADLs). Results suggested that bedtimes may be influenced by nighttime tasks. An understanding of these unique sleep patterns may facilitate the development of nonpharmacological, person-centered interventions for building sleep cycles around individual preferences versus facility-driven routines.
