Day workers suffering from a wider range of sleep problems are more likely to experience suicidality.

ABSTRACT: Both a higher suicide rate and widespread sleep problems are serious health concerns in Japan when compared with those of other countries. We investigated the relationship between suicidal ideation and sleep problems in Japanese day workers using the 3-dimensional sleep scale (3DSS), which measures three sleep elements (phase, quality, and quantity). Data from 635 Japanese day workers (461 mens and 174 womens) were included. The 3DSS was used to assess participants' sleep condition. Participants were classified into eight sleep types based on scores of phase, quality, and quantity: All Good Sleep, Owl (poor phase), Inefficient (poor quality), Short (poor quantity), Owl + Inefficient (poor phase and quality), Owl + Short (poor phase and quantity), Inefficient + Short (poor quality and quantity), and All Poor Sleep. We assessed participants' suicidal ideation using question 19 of the self-rating depression scale (SDS); 119 cases (18.7 %) had ratings of 2-4 for this question and were considered to have suicidal ideation. The higher the number of sleep problems, the higher the risk of suicidal ideation compared to sleep types not indicative of problems. All Poor Sleep had the highest risk of the eight sleep types. Individuals with Owl + Short, Inefficient + Short, or All Poor Sleep had a significant risk of suicidal ideation even after adjusting for hopelessness and nightmares. Our findings suggested that sleep problems assessed by the 3DSS were related to suicidal ideation. Analysis of various aspects of sleep could be helpful for suicide prevention.

Project description:PURPOSE:Sedation management of trauma patients after damage control laparotomy (DCL) has not been optimized. We evaluated if shorter sedation exposure was associated with increased proportion of delirium-free/coma-free (DF/CF-ICU) days and change in time to definitive fascial closure (DFC). METHODS:We reviewed trauma DCL patients at an ACS-verified level I center over 5 years as shorter (SE) or longer than median (LE) sedation exposure. We compared demographics, injury patterns, hemodynamic parameters, and injury severity between groups. We calculated the propensity for each patient to achieve DFC using age, gender, ISS, red blood cell transfusion, bowel discontinuity, abdominal vascular injury, and time to first takeback; we then determined the effect of sedation exposure on rate of DFC by multivariate Cox regression, adjusted for propensity to achieve DFC. We used linear regression adjusted for age, ISS, head-AIS, bowel discontinuity, and vascular injury to determine the effect of sedation exposure on the proportion of DF/CF-ICU days. RESULTS:65 patients (33.8% penetrating) had mean age 41.8?±?16.0, ISS 27.1?±?14.2, Head-AIS 1.2?±?1.6 and median sedation exposure of 2.2 [IQR 0.78, 7.3] days (35 SE and 30 LE). Pattern and severity of solid organ injuries and proportion of small and large bowel and vascular injuries were similar between groups. LE had more abdominal sepsis (23.3% vs 0%, p?=?0.003) and enterocutaneous fistula (16.7% vs 0%, p?=?0.016), and more ventilator (17.3?±?12.7 vs 6.1?±?6.8, p?<?0.001), ICU (20.8?±?14.2 vs 7.2?±?7.6, p?<?0.001), and hospital days (29.6?±?19.6 vs 13.9?±?9.0, p?<?0.001). DFC was achieved more rapidly in the SE group (2.0?±?1.5 days vs 3.9?±?3.7 days [unadjusted], p?=?0.023) and SE had a higher proportion of unadjusted DF/CF-ICU days (33.0?±?32.0% vs 18.1?±?16.4%, p?=?0.020). SE was associated with an increased proportion of adjusted DF/CF-ICU days by multivariate linear regression (13.1% [95% CI 1.4-24.8%], p?=?0.029) and with faster adjusted rate of DFC by multivariate Cox regression (RR 2.28 [95% CI 1.25-4.15, p?=?0.007]). CONCLUSIONS:Shorter sedation exposure is associated with increased proportion of DF/CF-ICU days and more rapid DFC after DCL for trauma.
