Global initiatives to reduce restrictive practices in mental health settings have gained increasing attention. However, discrepancies in restrictive practice rates create uncertainties about whether these variations reflect true differences in clinical practices or arise from inconsistent classification and reporting methods.

This study investigated how healthcare professionals classify and report potential restrictive practice scenarios, and examined variations in classification and documentation across diverse facilities.

This was an international survey conducted using an online questionnaire via the Qualtrics platform. Healthcare professionals working in adult mental health in-patient settings were recruited through multiple media platforms and snowball sampling. The questionnaire included 44 potential restrictive practice case scenarios. Participants rated each scenario as follows: (a) whether it should be classified as a restrictive practice; (b) whether it should be recorded as such; (c) whether it would be classified as a restrictive practice within their facility; and (d) whether it would be reported as a restrictive practice in their facility. Survey development was guided by systematic reviews and co-design work with stakeholders. Data were analysed using ordered regression models, with clustering by participant identity and country. Robust standard errors were applied to ensure accurate estimation of variability.

A total of 491 healthcare professionals from 41 countries participated. Results indicated substantial inconsistencies in clinicians’ perspectives regarding what constitutes restrictive practices and whether a given action should be reported as a restrictive practice. Although participants frequently identified scenarios as restrictive practices, their intention to report them was considerably lower. Additional discrepancies were observed between clinicians’ individual perspectives and their expectations of how these practices were actually being classified and reported as restrictive practices within the in-patient facilities where they work.

Discrepancies between healthcare professionals’ classification of restrictive practices and their reporting intentions, as well as between their perspectives and actual institutional practices, highlight potential errors in current reporting systems. These findings underscore the need for standardised definitions, enhanced reporting frameworks and structured training programmes and monitoring mechanisms to improve consistency in the management of restrictive practices across mental health settings.

This study aimed to compare Merocel and Surgicel nasal packing following inferior turbinoplasty, focusing on post-operative bleeding, pain, discomfort and nasal obstruction.

A randomised controlled trial (2017–2021) was conducted in the Department of Otolaryngology, Changi General Hospital, Singapore. Sixty adults undergoing inferior turbinoplasty and/or septoplasty were randomised to receive Merocel or Surgicel packing. Standardised surgical and post-operative protocols were used. Outcomes—bleeding, pain, discomfort and nasal obstruction—were assessed on post-operative day 1 and post-operative days 5–7 using validated scales.

Fifty-eight patients completed the study (Merocel = 30; Surgicel = 28). On post-operative day 1, Surgicel had significantly lower nasal obstruction scores (1.57 ± 0.74 vs 2.10 ± 0.71; p = 0.008). By post-operative days 5–7, Merocel showed significantly less bleeding (0.77 ± 0.63 vs 1.18 ± 0.86; p = 0.044). Pain and discomfort were comparable.

Merocel provided superior sustained haemostasis, while Surgicel offered better early comfort. Both materials have comparable outcomes.

This review highlights 10 recent advances in climate change research with high policy relevance, spanning diverse topics: (1) the global temperature jump of 2023–2024; (2) sea surface warming and marine heatwaves; (3) land carbon sinks; (4) interactions between climate change and biodiversity loss; (5) accelerated groundwater decline; (6) global dengue incidence; (7) income and labour productivity loss; (8) strategic considerations for scaling carbon dioxide removal (CDR); (9) integrity of carbon credit markets; and (10) policy mixes for climate change mitigation.

Interdisciplinary understanding is vital for delivering sound climate policy advice. However, navigating the ever-growing and increasingly diverse scholarly literature on climate change is challenging for any individual researcher. This annual synthesis highlights and explains recent advances across a variety of fields of climate change research. This year, the 10 insights focus on: (1) the record-warmth of 2023/2024 and the elevated Earth energy imbalance; (2) acceleration of ocean warming and intensifying marine heatwaves; (3) northern land carbon sinks under strain; (4) reinforcing feedback between biodiversity loss and climate change; (5) accelerated depletion of groundwater; (6) global dengue incidence; (7) global income losses and labour productivity declines; (8) strategic scaling of CDR; (9) integrity challenges in carbon credit markets and emerging responses; and (10) effective policy mixes for emissions reductions. The insights have been written to be accessible to researchers from different fields, serving as entry-points to specific topics, as well as providing an overview of the evolving landscape of climate change research. In the final section, the insights are used to develop overarching policy-relevant messages. This paper provides the basis for a science-policy report that was shared with all Party delegations ahead of COP30 in Belém, Brazil.

Estimate bacterial pathogen contamination of healthcare workers’ (HCW) long-sleeved attire.

Prospective observational study.

Tertiary care hospital.

HCWs wearing long-sleeved attire providing direct inpatient care.

Sampling of both sleeves of HCWs wearing long-sleeved attire was performed using a swab and cultured for aerobic bacterial growth classified as potential pathogens or presumptive skin commensals. Potential predictors of sleeve contamination, including participant survey responses related to attire and infection prevention practices, were analyzed using univariate analyses. Whole genome sequencing compared isolates to a genomic surveillance database of patient clinical isolates.

Among 280 samples, 81.1% (n = 227) demonstrated any bacterial growth and 20.7% (n = 58) grew ≥1 potential pathogen. Speciated organisms included alpha-hemolytic streptococci (n = 28), Bacillus sp. (n = 20), and Pantoea/Mixta sp. (n = 8), gram-negative bacilli (n = 6), and Staphylococcus aureus (n = 2). Univariate analysis demonstrated that sleeves sampled on non-intensive care units (P = .038) were significantly associated with any bacterial growth, and attire type (P = .002) and sleeve material (P = .004) were associated with growth of ≥1 potential pathogen. Fleece attire and material were more likely to be contaminated than other attire and material types. Sequenced isolates from sleeve samples were not genetically related to any patient isolates.

HCW long sleeve contamination occurs frequently, including with potential pathogens. Changing trends in attire type may have an impact on bacterial transmissibility. While this study could not infer transmission events associated with clinically diagnosed patient infections, the potential benefit of a “bare below the elbows” attire policy warrants further investigation.

Efforts to reduce restrictive practices (RPs) in mental health care are growing internationally. Yet, inconsistent definitions and perspectives often challenge the consistent implementation and evaluation of reduction strategies. This study explored which scenarios different mental health stakeholders classify as RPs, examined the contextual factors influencing these classifications and compared classification patterns across clinicians, researchers, service users and family caregivers.

An international cross-sectional survey was conducted using a multilingual online questionnaire hosted on the Qualtrics platform. A total of 851 stakeholders participated, including clinicians (n = 517), service users (n = 80), family caregivers (n = 89) and researchers (n = 165). Participants were presented with 44 potential RP case scenarios and asked to rate whether each scenario should be classified as an RP using a four-point Likert scale (Definitely yes, Probably yes, Probably no, Definitely no). The scenarios were organized into 22 paired comparisons, each sharing the same core context but differing in specific details. Paired comparisons were analyzed one pair at a time, allowing us to identify classification patterns between the scenarios and isolate the effects of particular contextual factors using ordered logistic regression. Interaction analyses were then conducted to assess how classification patterns varied across stakeholder groups.

Substantial discrepancies exist both within and between stakeholder groups regarding whether a given action should be considered an RP or not. Physically visible actions were often identified as RPs across all groups, while less visible forms often went unrecognized. Contextual differences, such as the healthcare professional’s intention, duration of the action, methods used, presence or absence of consent, door-locking status, and the severity of anticipated harm to be prevented influenced whether a given action was classified as an RP. Service users classified more scenarios as RPs than other groups; however, their decisions were more context-sensitive, shifting notably even with minor changes in scenario details. Among the 22 paired scenarios compared, 13 (59.09%) showed significant differences (p < 0.01) within at least one stakeholder group and eight demonstrated differences between groups.

Mental health stakeholders’ interpretations of RPs were often shaped not only by the inherent coercive nature of actions but also by the context in which they occurred and the professional role of the assessors. This underscores the need for harmonized definitions and classification frameworks for RPs, co-designed with diverse stakeholders. Addressing less visible forms of RPs in policy and clinical practice is also essential.

This study evaluated whether brief teaching sessions on transference-focused psychotherapy (TFP) could improve psychiatric trainees’ attitudes and clinical confidence in managing patients with personality disorders. A mixed-methods design was used, combining pre- and post-training validated questionnaires with a focus group discussion. Two 4-h workshops covered TFP theory and techniques, and case discussions.

Twenty-six participants completed paired questionnaires. Statistically significant improvements were observed in overall attitudes (Attitudes to Personality Disorder Questionnaire total score, P = 0.022) and enthusiasm towards patients with personality disorders (P = 0.003). Clinical confidence (Clinical Confidence with Personality Disorder Questionnaire) improved markedly (P < 0.001). Qualitative analysis identified high acceptability, valuing TFP concepts and enhanced emotional awareness, although participants desired more practical components.

Even brief TFP training can positively influence trainees’ attitudes and confidence in treating personality disorders. Incorporating TFP-informed training into psychiatric education may reduce clinician frustration and improve therapeutic engagement with this complex patient group.

Non-suicidal self-injury (NSSI) is associated with mental disorders, yet work regarding the direction of this association is inconsistent. We examined the prevalence, comorbidity, time–order associations with mental disorders, and sex differences in sporadic and repetitive NSSI among emerging adults.

We used survey data from n = 72,288 first-year college students as part of the World Mental Health-International College Student Survey Initiative (WMH-ICS) to explore time–order associations between onset of NSSI and mental disorders, based on retrospective age-of-onset reports using discrete-time survival models. We distinguished between sporadic (1–5 lifetime episodes) and repetitive (≥6 lifetime episodes) NSSI in relation to DSM-5 mood, anxiety, and externalizing disorders.

We estimated a lifetime NSSI rate of 24.5%, with approximately half reporting sporadic NSSI and half repetitive NSSI. The time–order associations between onset of NSSI and mental disorders were bidirectional, but mental disorders were stronger predictors of the onset of NSSI (median RR = 1.94) than vice versa (median RR = 1.58). These associations were stronger among individuals engaging in repetitive rather than sporadic NSSI. While associations between NSSI and mental disorders generally did not differ by sex, repetitive NSSI was a stronger predictor for the onset of subsequent substance use disorders among females compared to males. Most mental disorders marginally increased the risk for persistent repetitive NSSI (median RR = 1.23).

Our findings offer unique insights into the temporal order between NSSI and mental disorders. Further work exploring the mechanism underlying these associations will pave the way for early identification and intervention of both NSSI and mental disorders.

Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.

T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).

PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).

PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.
