How are psychological capital and emotion regulation associated with schoolteachers’ burnout? A systematic review

Teachers are one of the professions that suffer from burnout, which has negative effects not only on teachers but also on their students. This systematic review aimed to examine the relationships between psychological capital, emotion regulation, and burnout among schoolteachers. The review was based on electronic databases including SCOPUS, PubMed, and ERIC and included 10 original articles that met the inclusion and exclusion criteria. The findings showed that higher levels of psychological capital and emotion regulation were negatively associated with burnout and its dimensions. Additionally, cognitive reappraisal was found to have a negative effect on burnout, while expressive suppression was positively associated with burnout. This systematic review could be useful in developing interventions and guidelines to improve psychological capital and emotion regulation, and prevent burnout in schoolteachers, leading to better well-being

In the psychiatrist's chair: how neurologists understand conversion disorder

Conversion disorder (‘hysteria’) was largely considered to be a neurological problem in the 19th century, but without a neuropathological explanation it was commonly assimilated with malingering. The theories of Janet and Freud transformed hysteria into a psychiatric condition, but as such models decline in popularity and a neurobiology of conversion has yet to be found, today's neurologists once again face a disorder without an accepted model. This article explores how today's neurologists understand conversion through in-depth interviews with 22 neurology consultants. The neurologists endorsed psychological models but did not understand their patients in such terms. Rather, they distinguished conversion from other unexplained conditions clinically by its severity and inconsistency. While many did not see this as clearly distinct from feigning, they did not feel that this was their problem to resolve. They saw themselves as ‘agnostic’ regarding non-neuropathological explanations. However, since neurologists are in some ways more expert in conversion than psychiatrists, their continuing support for the deception model is important, and begs an explanation. One reason for the model's persistence may be that it is employed as a diagnostic device, used to differentiate between those unexplained symptoms that could, in principle, have a medical explanation and those that could not

Effect of Tiliacora triandra leaf extract on glycemic control in mice with high sugar intake

Prediabetes is associated with sugar-sweetened beverages and sugar-rich processed foods. High sugar intake (HSI), which is represented as save dose, may silently alter the glycemic control. The present study investigated the effect of HSI and Tiliacora triandra (TT21) leaf extract on the glycemic control in mice. Eighteen male ICR mice were divided into three groups of Control-HSI, HSI-TT300 and HSI-TT600 that received 4 weeks of 30% glucose with a vehicle of T. triandra leaf extract 300 and 600 mg/kg, respectively. The blood glucose, serum insulin, glucose clearance, liver and muscle glycogen contents and tissue oxidative status were evaluated. The results showed that HSI increased the blood glucose (w2 and w3: p<0.05) and serum insulin levels (w3 and w4: p<0.05) with glucose intolerance (w4: 30, 60 and 90 min, p<0.05). T. triandra leaf extract reduced the blood glucose and serum insulin and increased the glycogen content in the liver and muscle tissues (p<0.05). We concluded that HSI silently induced an alteration of the glycemic control in the normal mice, and the T. triandra leaf extract nurtured the glycemic control in the HSI mice by lowering the blood glucose and serum insulin and increasing the liver and muscle glycogen contents, which indicated an involvement of peripheral insulin sensitivity

Evaluation of Psychometric Properties of Thai Version Telehealth Usability Questionnaire (T-TUQ)

This cross-sectional validation study aimed to translate, cross-culturally adapt, and investigate the psychometric properties of a Thai version of the Telehealth Usability Questionnaire (T-TUQ). Two hundred and ten Thai participants, mean age of 61.2±15.2 years, were recruited from three specialty clinics: 50 (23.8%) hematology, 70 (33.3%) movement disorders, and 90 (42.9%) general neurology. The T-TUQ was translated from the original English version to produce a Thai language version. Back translation and pilot cognitive interviews were completed. All five subscales (usefulness, ease of use, effectiveness, reliability, and satisfaction) showed excellent internal consistency (alpha &gt;0.80), displayed by Cronbach's alpha coefficient of 0.83, 0.94, 0.86, 0.83, and 0.92, respectively. For construct validity, exploratory factor analysis revealed two dimensions from eigenvalues and scree plot, defined as utility and accessibility subscales. In conclusion, the T-TUQ could be a reliable and valid instrument to evaluate the usability of telehealth with a Thai population

Prevalence of somatisation and psychologisation among patients visiting primary health care centres in the State of Qatar

Background: Medically unexplained somatic complaints are among the most common clinical presentations in primary care in developing countries and they are considerable burden for patients and health care system. Objectives: The aim of this study was to determine the prevalence of somatisation in comparison to psychologisation among a sample of Qatari patients who were visiting primary health care (PHC) centres and to investigate the clinical and socio-demographic characteristics of somatisers (STs) and psychologisers (PGs). Method: The survey was conducted among PHC Qatari patients during the period from January to July 2007. About 2,320 patients were approached, of whom 1,689 agreed to participate and responded to the questionnaire. Among the studied Qatari patients, 404 patients were identified for clinical interview. The first stage of the study was conducted with the help of general practitioners, using the 12-item General Health Questionnaire. The second stage was carried out by a consultant using the Clinical Interview Schedule. A specific operational criterion was used to identify STs and PGs. Results: The prevalence rate of STs among the total studied sample was 12.4%, while the PGs were 11.5%. Among the identified psychiatric cases, the proportion of STs (52%) was higher than PGs (48%). Most of the diagnostic categories were more prevalent among PGs. The dissatisfaction at work and stressful life events within 12 months before the onset of the presenting symptoms were the three postulated determinants which were significantly more among STs than PGs. Conclusion: The prevalence of somatised mental disorder was little higher than the psychologised mental disorder. The prevalence of somatisation and psychologisation is comparable with other reported studies from the Middle-East and Western countries. Dissatisfaction at work and stressful life events were significantly higher among STs than PGs

Illness behavior in patients on long-term sick leave due to chronic musculoskeletal pain

Background and purpose Methods for identification of patients with illness behavior in orthopedic settings are still being debated. The purpose of this study was to test the association between illness behavior, depressed mood, pain intensity, self-rated disability, and clinical status in patients with chronic musculoskeletal pain (CMP)

Predictors of increased affective symptoms and suicidal ideation during the COVID-19 pandemic: results from a large-scale study of 14 271 Thai adults

Background Increasing data suggest emergent affective symptoms during the COVID-19 pandemic. Objectives To study the impact of the COVID-19 pandemic on affective symptoms and suicidal ideation in Thai adults. Methods The Collaborative Outcomes Study on Health and Functioning during Infection Times uses non-probability sampling (chain referring and voluntary response sampling) and stratified probability sampling to identify risk factors of mental health problems and potential treatment targets to improve mental health outcomes during pandemics. Findings Analysing 14 271 adult survey participants across all four waves of the COVID-19 pandemic in Thailand, covering all 77 provinces from 1 June 2020 to 30 April 2022, affective symptoms and suicidality increased during COVID-19 pandemic. Affective symptoms were strongly predicted by pandemic (feelings of isolation, fear of COVID-19, loss of social support, financial loss, lack of protective devices) and non-pandemic (female sex, non-binary individuals, adverse childhood experiences (ACEs), negative life events, student status, multiple mental health and medical conditions, physical pain) risk factors. ACEs, prior mental health conditions and physical pain were the top three risk factors associated with both increased affective symptoms and suicidal ideation during the COVID-19 pandemic. Partial least squares analysis showed that ACEs were the most important risk factor as they impacted most pandemic and non-pandemic risk factors. Clinical implications Rational policymaking during a pandemic should aim to identify the groups at highest risk (those with ACEs, psychiatric and medical disease, women, non-binary individuals) and implement both immediate and long-term strategies to mitigate the impact of ACEs, while effectively addressing associated psychiatric and medical conditions

Positive relationships between association strength and phenotypic similarity characterize the assembly of mixed-species bird flocks worldwide

Competition theory predicts that local communities should consist of species that are more dissimilar than expected by chance. We find a strikingly different pattern in a multicontinent data set (55 presence-absence matrices from 24 locations) on the composition of mixed-species bird flocks, which are important sub-units of local bird communities the world over. By using null models and randomization tests followed by meta-analysis, we find the association strengths of species in flocks to be strongly related to similarity in body size and foraging behavior and higher for congeneric compared with noncongeneric species pairs. Given the local spatial scales of our individual analyses, differences in the habitat preferences of species are unlikely to have caused these association patterns; the patterns observed are most likely the outcome of species interactions. Extending group-living and social-information-use theory to a heterospecific context, we discuss potential behavioral mechanisms that lead to positive interactions among similar species in flocks, as well as ways in which competition costs are reduced. Our findings highlight the need to consider positive interactions along with competition when seeking to explain community assembly

Acrocephalus orinus: A Case of Mistaken Identity

Recent discovery of the Large-billed Reed Warbler (Acrocephalus orinus) in museums and in the wild significantly expanded our knowledge of its morphological traits and genetic variability, and revealed new data on geographical distribution of the breeding grounds, migration routes and wintering locations of this species. It is now certain that A. orinus is breeding in Central Asia; however, the precise area of distribution remains unclear. The difficulty in the further study of this species lies in the small number of known specimens, with only 13 currently available in museums, and in the relative uncertainty of the breeding area and habitat of this species. Following morphological and genetic analyses from Svensson, et al, we describe 14 new A. orinus specimens from collections of Zoological Museums of the former USSR from the territory of Central Asian states. All of these specimens were erroneously labeled as Blyth's Reed Warbler (A. dumetorum), which is thought to be a breeding species in these areas. The 14 new A. orinus specimens were collected during breeding season while most of the 85 A. dumetorum specimens from the same area were collected during the migration period. Our data indicate that the Central Asian territory previously attributed as breeding grounds of A. dumetorum is likely to constitute the breeding territory of A. orinus. This rare case of a re-description of the breeding territory of a lost species emphasizes the importance of maintenance of museum collections around the world. If the present data on the breeding grounds of A. orinus are confirmed with field observations and collections, the literature on the biology of A. dumetorum from the southern part of its range may have to be reconsidered
