Emotion malleability beliefs matter in emotion regulation: a comprehensive review and meta-analysis

ABSTRACT Individuals’ beliefs about the malleability of emotions have been theorised to play a role in their psychological distress by influencing emotion regulation processes, such as the use of emotion regulation strategies. We conducted a meta-analysis to test this idea across studies with a focus on the relationships between emotion malleability beliefs and five distinct emotion regulation strategies: cognitive reappraisal, suppression, avoidance, rumination, and acceptance. Further, using two-stage meta-analytic structural equation modelling (TSSEM), we examined whether the emotion regulation strategies mediate the cross-sectional relationship between emotion malleability beliefs and psychological distress across studies. Thirty-seven studies were included in the meta-analyses and 55 cross-sectional studies were included in the TSSEM. Results demonstrated that, across studies, emotion malleability beliefs were significantly associated with greater use of putatively helpful strategies (particularly with cognitive reappraisal) and less use of putatively unhelpful strategies (particularly with avoidance). The use of cognitive reappraisal and avoidance partially mediated the relationship between emotion malleability beliefs and psychological distress. These results highlight the importance of considering beliefs about the malleability of emotions in the context of emotion regulation. These findings suggest the potential role of emotion malleability beliefs in interventions for individuals with emotion regulation-related difficulties and psychological distress.

Criminal responsibility and profile of Turkish firesetters with schizophrenia

This study aimed to examine a subgroup of Turkish firesetters diagnosed with schizophrenia spectrum disorders (SSD) for their motives, individual and offense-related characteristics and courses of action, and their association with expert assessment of criminal responsibility. A cohort of 50 arsonists with SSD, who underwent assessment for criminal responsibility by the Council of Forensic Medicine in Turkiye between 2009 and 2022, was analyzed using a comprehensive retrospective file review. Multivariate analyses indicated that being female, older, experiencing hallucinations at the time of the offense, having a primary diagnosis of SSD other than psychotic disorder not otherwise specified, and no prior convictions were associated with a higher likelihood of being found not criminally responsible. Singling out a definitive profile of SSD arsonists without criminal responsibility is challenging. Our findings, based on forensic expert assessments, suggest that positive psychotic symptoms and criminal history play crucial roles in determining criminal responsibility in this group.

ORAL OPIOID ANALGESICS VS SPINAL STEROID INJECTIONS IN THE TREATMENT OF LOW BACK PAIN: A COMPREHENSIVE SYSTEMATIC REVIEW

Introduction: Low back pain (LBP) affects a significant portion of the population worldwide, with distinct treatment needs for acute and chronic cases. Despite widespread opioid use, evidence for their efficacy in LBP remains uncertain, highlighting the need for alternative interventions. Minimally invasive procedures like epidural steroid injections offer potential relief for conditions like lumbar disc herniation, but their effectiveness is debated. To address these complexities, we conducted a comprehensive review encompassing various treatment modalities beyond medication, aiming to optimize outcomes and improve quality of life for individuals with LBP. Method: The researchers in this study followed the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines to ensure that their work met the required standards. This was done to ensure the precision and reliability of the conclusions derived from the research. Result: Our search produced 13 results. After looking at the titles and summaries, we found 8 papers that fit our criteria. At first, we excluded several articles because they were written in review style and case reports. But after reading the full papers carefully, we included four papers in our final analysis. These papers included retrospective analysis, a randomized, double blind, placebo controlled cross-over study, noninterventional, retrospective 12-week study using anonymized clinical practice data from the German Pain eRegistry, and a retrospective analysis of anonymized, propensity score–matched data. Conclusion: Favorable post-injection outcomes suggest the blind method for caudal epidural injections is safe and effective, suitable for patients not eligible for surgery or unresponsive to conservative treatments. Interlaminar epidural steroid injections effectively reduce VAS and ODI scores in patients with chronic low back pain and multi-level disc disease, but further research is needed to standardize administration protocols and optimize treatment outcomes, including addressing BMI's impact. The analgesic efficacy of periradicular meloxicam injections for acute/subacute low back pain, indicating a potential new treatment option, while real-world data suggest NBX oromucosal spray may be superior to typical oral LAO analgesics for severe peripheral NBP, pending confirmation in large RCTs.

Annotated checklist of the megachilid bees of Corsica (Hymenoptera, Megachilidae)

Corsica stands as one of the largest Mediterranean Islands and has been the exploration ground for renowned entomologists like Charles Ferton. However, no synthesis on Corsican bees has been published so far. To fill this gap in knowledge, we propose an overview of the megachilid bee fauna of the island based on fieldwork, a thorough examination of material housed at the Muséum national d’Histoire naturelle (MNHN, Paris), data compilation from various collections and a comprehensive review of existing literature. We reviewed 5,886 specimens and we extracted 279 additional data from literature sources. These data confirm the presence in Corsica of 91 species of which two are endemic, including Hoplitis corsaria (Warncke, 1991) which is elevated to species rank stat. nov. One new synonymy is established: Megachile lucidifrons Ferton, syn. nov. of Megachile albocristata Smith, 1853. The presence in Corsica of 19 species is regarded as dubious or erroneous. Finally, the types of Megachilid bees housed at MNHN and described based on Corsican material are illustrated. Lectotypes are designated for Megachile sicula var. corsica Benoist, 1935, Osmia corsica Ferton, 1901, Osmia erythrogastra Ferton, 1905, Osmia lanosa Pérez, 1879, and Osmia lineola Pérez, 1895.

Photoinduced Generation of Active Intermediates from Unmodified 1,3‐Dicarbonyl Compounds for Organic Transformations

AbstractPhotocatalysis utilizes light as the initial driving force for chemical reactions, enabling reactions with high energy barriers in traditionally thermal chemistry to proceed under mild conditions. 1,3‐Dicarbonyl compounds occur as important active molecules in nature and are intermediates in pharmaceutical syntheses. In recent years, there have been numerous studies of these compounds, and it is common practice to pre‐modify them before the reaction, which is, however, unfavorable for the atom economy of the process. This paper provides a comprehensive review of the latest advancements in the site‐specific activation of unmodified 1,3‐dicarbonyl compounds by photoinduction. The focus is on elucidating the mechanisms of these reactions to provide insights and directions for future research in designing novel reactions.
