Bipolar disorder and oxidative stress: A bibliometric perspective.

Objective: Accumulating evidence indicates that oxidative stress and the disruption of antioxidant defenses play an important role in the neurobiology of bipolar disorder (BD). Studies have found that increased oxidative stress may be associated with cell apoptosis and neuronal damage in BD patients. Hence, this study explored the research field related to BD and oxidative stress from a bibliometrics perspective.

Catatonia.

Catatonia is a neuropsychiatric disorder characterized by motor, affective and cognitive-behavioural signs, which lasts from hours to days. Intensive research over the past two decades has led to catatonia being recognized as an independent diagnosis in the International Classification of Diseases, 11th Revision (ICD-11) since 2022. Catatonia is found in 5-18% of inpatients on psychiatric units and 3.

First 150 years of catatonia: Looking back at its complicated history and forward to the road ahead.

Karl Ludwig Kahlbaum (1828-1899) was the first to conceptualize and describe the main clinical features of a novel psychiatric illness, which he termed catatonia in his groundbreaking monograph published 150 years ago. Although Kahlbaum postulated catatonia as a separate disease entity characterized by psychomotor symptoms and a cyclical course, a close examination of his 26 cases reveals that most of them presented with motor symptom complexes or syndromes associated with various psychiatric and medical conditions. In his classification system, Kraepelin categorized catatonic motor symptoms that occur in combination with psychotic symptoms and typically have a poor prognosis within his dementia praecox (schizophrenia) disease entity.

Global prevalence of major depressive disorder in LGBTQ+ samples: A systematic review and meta-analysis of epidemiological studies.

Background: LGBTQ+ populations have been reported to have higher rates of depression compared with their heterosexual peers. Such data provided us the impetus to conduct a meta-analysis on the worldwide prevalence of major depressive disorder (MDD) in LGBTQ+ populations and moderating factors that contributed to differences in prevalence estimates between studies.

Methods: A systematic literature search was performed in major international (PubMed, PsycINFO, Web of Science, EMBASE) and Chinese (Chinese Nation Knowledge Infrastructure (CNKI) and WANFANG) databases from dates of inception to 10 December 2021.

Inter-relationships of depression and insomnia symptoms with life satisfaction in stroke and stroke-free older adults: Findings from the Health and Retirement Study based on network analysis and propensity score matching.

Background: Depression and insomnia are common co-occurring psychiatric problems among older adults who have had strokes. Nevertheless, symptom-level relationships between these disorders remain unclear.

Objectives: In this study, we compared inter-relationships of depression and insomnia symptoms with life satisfaction among older stroke patients and stroke-free peers in the United States.

Pain trajectories and their associations with cognition among older adults: a 10-year cohort study from network perspective.

Background: Few studies have examined the associations between pain trajectories and cognitive function in older adults. This study explored the associations between pain trajectories and different cognitive domains in older adults from a network perspective.

Methods: Data on pain trajectories were derived from the Health and Retirement Study between 2010 and 2020 using latent class growth analyses.

The prevalence of poor sleep quality in the general population in China: a meta-analysis of epidemiological studies.

Background: The high prevalence of poor sleep quality (PSQ) in the general population leads to negative health outcomes. Since estimates of PSQ prevalence in the Chinese general population vary widely, this meta-analysis aimed to refine these estimates and to identify moderating factors.

Methods: A comprehensive literature search was undertaken in both international (PubMed, PsycINFO, Web of Science, and EMBASE) and Chinese (Wanfang, and the China National Knowledge Infrastructure databases) databases from inception to 23 November 2023.

Interactive changes in depression and loneliness symptoms prior to and during the COVID-19 pandemic: A longitudinal network analysis.

Objectives: Depression and loneliness co-occur frequently. This study examined interactive changes between depression and loneliness among older adults prior to and during the COVID-19 pandemic from a longitudinal network perspective.

Methods: This network study was based on data from three waves (2016-2017, 2018-2019, and 2020) of the English Longitudinal Study of Ageing (ELSA).

COVID-19 and Sleep Problems: A Perspective from Bibliometric Analysis.

Objectives: The Coronavirus Disease 2019 (COVID-19) pandemic and the containment measures for COVID-19 have affected sleep quality in the population. This study explored sleep-related research from a bibliometric perspective to provide an overview of the research outputs in this field.

Methods: Original and review articles were retrieved from the Web of Science Core Collection (WOSCC) database from December 2019 to 7 Aug 2023.

Prevalence of COVID-19 fear and its association with quality of life and network structure among Chinese mental health professionals after ending China's dynamic zero-COVID policy: a national survey.

Background: China recorded a massive COVID-19 pandemic wave after ending its Dynamic Zero-COVID Policy on January 8, 2023. As a result, mental health professionals (MHPs) experienced negative mental health consequences, including an increased level of fear related to COVID-19. This study aimed to explore the prevalence and correlates of COVID-19 fear among MHPs following the end of the Policy, and its association with quality of life (QoL) from a network analysis perspective.

The relationship of intent to be COVID-19 vaccinated with depression, anxiety, insomnia, pain and smoking among Chinese patients with a pacemaker.

Background: This study examined the intent to be COVID-19 vaccinated and its correlates among patients with a pacemaker.

Methods: This observational study was carried out between July 1, 2021, and May 17, 2022 in Beijing, China. Patients with a pacemaker were consecutively invited by a research physician to participate in the study.

Bilateral theta burst stimulation for patients with acute unipolar or bipolar depressive episodes: A systematic review of randomized controlled studies.

Objective: This meta-analysis of randomized controlled trials (RCTs) evaluated the overall efficacy and safety of bilateral theta-burst stimulation (TBS) as an intervention for patients with mood disorders.

Methods: A systematic search (up to December 7, 2022) of RCTs was conducted to address the study aims. A random-effects meta-analysis was performed by including study-defined responses and remission as primary outcomes.

Hikikomori: A perspective from bibliometric analysis.

Aims: Hikikomori is a common phenomenon reported in Japan and many other countries. However, the broad trends of the research publications on hikikomori are unclear. Therefore, this study examined the patterns of research on hikikomori using bibliometric analysis.
