Background: Police work is currently one of the most stressful occupations. High levels of stress can culminate in suffering the burnout syndrome. This syndrome is characterised by emotional exhaustion, depersonalisation and low personal accomplishment. Police officers, despite being a risk group, have been investigated less than other professional groups. The objectives of the current work are to estimate the prevalence of burnout syndrome in police officers, to present a classification of the syndrome and to identify some risk factors (socio-demographic, personality, and work-related).
Method: A cross-sectional study was carried out with 747 national police officers from Andalucía (Spain).
Results: The prevalence of burnout is high. Furthermore, individual differences, and in particular, personality factors, are important to explain the development of burnout.
Conclusions: Police officers are a risk group and, therefore, actions aimed at reducing the levels of burnout among these professionals should be developed.

Background: Endurance athletes tend to accumulate large training volumes, the majority of which are performed at a low intensity and a smaller portion at moderate and high intensity. However, different training intensity distributions (TID) are employed to maximize physiological and performance adaptations.
Objective: The objective of this study was to conduct a systematic review and network meta-analysis of individual participant data to compare the effect of different TID models on maximal oxygen uptake (VO) and time-trial (TT) performance in endurance-trained athletes.

Carbon-based perovskite solar cells (C-PSCs) exhibit notable stability and durability. However, the power conversion efficiency (PCE) is significantly hindered by energy level mismatches, which result in interfacial charge transport barriers at the electrode-related interfaces. Herein, we report a back electrode that utilizes atomically dispersed metallic cobalt (Co) in carbon nanosheets (Co/CN) to adjust the interfacial energy levels.

Adverse drug reactions pose a significant threat to patient safety and public health and often become apparent only after widespread clinical use. Mendelian randomization (MR) analysis is a valuable tool that can be used to infer causality by using genetic variants as instrumental variables, which can predict the occurrence of adverse drug reactions before they occur. Compared with traditional observational studies, MR Analysis can reduce the potential bias of confounding factors.

Pharmacologic beta-blockade is a well-established therapy for reducing adverse effects from sympathetic overactivity in cardiovascular diseases, such as heart failure. Despite decades of research efforts, in vivo cardiac functional studies utilizing genetic animal models remain scant. We generated a mouse model of cardiomyocyte-specific deletion of beta-1 adrenergic receptor (ADRB1) , the primary subtype expressed in cardiac myocytes, and demonstrated the role for ADRB1 in the maintenance of cardiac function at baseline and during exposure to increase in cardiac afterload by transient aortic occlusion and increasing heart rates (HRs) via atrial pacing.
