Bedtime procrastination (BP) has been proven to be an important indicator of sleep insufficiency from a psychological perspective. However, the effect of BP on sleep patterns related to sleep deficiency remains unknown.

This study aimed to investigate the characteristics of self-reported sleep timing and hygiene practices between high and low-moderate bedtime procrastinators. It also aimed to examine the relationship between these characteristics and high level of BP.

A total of 391 Chinese college students were recruited for this study. Participants completed questionnaires on demographics, sleep timing variables, the Sleep Hygiene Practice Scale (SHPS) and the Bedtime Procrastination Scale (BPS).

High bedtime procrastinators were more likely to have higher SHPS global and subdomain scores (Ps < 0.001). They also were more likely to exhibit later sleep onset, sleep offset and rise time on both weekdays and weekends (Ps < 0.01). The significant independent determinant factors of the prevalence of high BP were SHPS total score [odds ratio (OR) = 1.05, P < 0.001], arousal-related behaviour (OR = 1.07, P = 0.007), sleep schedule and timing (OR = 1.12, P < 0.001) and sleep onset on weekdays (OR = 2.65, P < 0.001).

High bedtime procrastinators showed maladaptive sleep-related variables, which mainly manifested as changes in arousal-related behaviour and sleep schedule and timing, as well as delays in sleep onset time on weekdays. The findings could help guide the formulation of appropriate interventions in primary health care.

Such analyses are employed as an attempt to balance potential or actual pain or distress imposed on laboratory animals against scientists' justifications for those impositions. The outcomes of those analyses are then supposed to be included in an official assessment of whether a given animal protocol should be approved as proposed. While commendable in theory as a means to avoid or minimize animal suffering, HBAs come with a flawed premise. Establishing an accurate prediction of benefit, especially for so-called "basic" research (vs "applied" research, such as in vivo testing for product development or batch release), is often impossible given the uncertain nature of experimental outcomes and the eventual value of those results. That impossibility, in turn, risks disapproving a legitimate research proposal that might have yielded important new knowledge if it had been allowed to proceed. Separately, the anticipated harm to which the animal would be subjected should similarly be scrutinized with an aim to refine that harm regardless of purported benefits if the protocol is approved. The intentions of this essay are to reflect on the potential harm and benefit of the HBA itself, highlight how HBAs may be helpful in advancing refinements, and propose alternative approaches to both parts of the equation in the assessment process.MicroRNAs (miRNAs) are small non-coding RNAs that negatively regulate target mRNAs at the post-transcriptional level. Increasing evidence shows the involvement of miRNAs in diverse biological processes. miR-302/367 cluster is highly conserved among vertebrates and made up of five members, including miR-367, miR-302a, miR-302b, miR-302c and miR-302d. miR-302/367 cluster plays an important role in cell proliferation, differentiation and reprogramming, affecting the development of tumor, cardiovascular system, nervous system and immune system. In this review, we will summarize the role of miR-302/367 cluster in embryonic stem cells and induced pluripotent stem cells and try to point out its relationship with tumors, cardiovascular system, nervous system and immune system.Interleukin-5 (IL-5) is manifested as its involvement in the process of atherosclerosis, but the mechanism is still unknown. In this study, we explored the effect of IL-5 on lipid metabolism and its underlying mechanisms in THP-1-derived macrophages. The quantitative polymerase chain reaction (qPCR) and western blot analysis results showed that IL-5 significantly up-regulated ATP-binding cassette transporter A1 (ABCA1) expression in a dose-dependent and time-dependent manner. [3H]-labeled cholesterol was used to assess the levels of cholesterol efflux, and the results showed that IL-5 increased ABCA1-mediated cholesterol efflux. A high-performance liquid chromatography assay indicated that cellular cholesterol content was decreased by IL-5 treatment in THP-1-derived macrophages. The selective inhibitor and small interfering RNA were used to block the Janus kinase (JAK)/signal transducer and activator of transcription 3 (STAT3) pathway. The results of the qPCR and western blot analysis showed that IL-5 activated JAK2/STAT3 pathway to up-regulate ABCA1 expression. Meanwhile, IL-5 reduced the expression level of miR-211. Furthermore, we found that JAK2 is a target gene of miR-211 and miR-211 mimic inhibited the expression of JAK2 and reduced the levels of p-STAT3 and ABCA1 as revealed by luciferase reporter assay, qPCR and western blot analysis. read more In summary, these findings indicated that IL-5 promotes ABCA1 expression and cholesterol efflux through the miR-211/JAK2/STAT3 signaling pathway in THP-1-derived macrophages.

Imipenem combined with the β-lactamase inhibitor relebactam has broad antibacterial activity, including against carbapenem-resistant gram-negative pathogens. We evaluated efficacy and safety of imipenem/cilastatin/relebactam in treating hospital-acquired/ventilator-associated bacterial pneumonia (HABP/VABP).

This was a randomized, controlled, double-blind phase 3 trial. Adults with HABP/VABP were randomized 11 to imipenem/cilastatin/relebactam 500 mg/500 mg/250 mg or piperacillin/tazobactam 4 g/500 mg, intravenously every 6 hours for 7-14 days. The primary endpoint was day 28 all-cause mortality in the modified intent-to-treat (MITT) population (patients who received study therapy, excluding those with only gram-positive cocci at baseline). The key secondary endpoint was clinical response 7-14 days after completing therapy in the MITT population.

Of 537 randomized patients (from 113 hospitals in 27 countries), the MITT population comprised 264 imipenem/cilastatin/relebactam and 267 piperacillin/tazobactam patients; 48.
