Suicide seasonality

OBJECTIVE: To assess whether male elite football players, during and after their active career, were at increased risk of depression and anxiety-related disorders and suicide, as compared with the general male population. METHODS: We included male football players active in the Swedish top division 1924-2019 and general male population (matched to football players based on age and region of residence) aged <65 years in 1997. Using nationwide registers, we followed the football players from their first season in the top division (or the date of their first registered residency in Sweden) or 1 January 1997, and compared the risk of depression and anxiety-related disorders (captured through diagnoses from hospital admissions and outpatient visits, and use of prescription drugs) among football players versus controls...

Insomnia plays a critical role in the onset and maintenance of Major Depressive Episode (MDE). Cognitive behavioral therapy for insomnia (CBT-I) can successfully improve the sleep of patients with insomnia and MDE. Nonetheless, the factors influencing CBT-I's effects in MDE remain uncertain. This study aimed to identify predictors of insomnia improvement following CBT-I, as well as predictors of insomnia response, remission in patients with MDE and specific insomnia subtypes. Initially, we compared a 4-session weekly CBT-I treatment to baseline sleep education (SE) in a control group...

Reproductive costs must be balanced with survival to maximise lifetime reproductive rates; however, some organisms invest in a single, suicidal bout of breeding known as semelparity. The northern quoll (Dasyurus hallucatus) is an endangered marsupial in which males, but not females, are semelparous. Northern quolls living near mining sites on Groote Eylandt, Northern Territory, Australia, accumulate manganese (Mn) in their brains, testes, and hair, and elevated Mn impacts motor performance. Whether Mn is associated with other health declines is yet unknown...

INTRODUCTION: During the pandemic years in Hungary, the completed suicide rates have risen significantly. Violent suicide attempts represent the majority of completed suicides. OBJECTIVE: In our study, we analyzed the change of the number of inpatients treated in Dr. Manninger Jenő National Traumatology Center between 2016 and 2021 due to violent suicide attempts, focusing on the trend in the first two years of the pandemic outbreak. METHOD: We used an interrupted time-series analysis with Prais-Winsten regression, controlling autoagressive and seasonal effects, to estimate the effect of the pandemic on the violent suicide attempt rates in our sample...

BACKGROUND: The COVID-19 pandemic and associated lockdowns were predicted to have a major impact on suicidal behaviour, including self-harm. However, current studies have produced contradictory findings with limited trend data. AIMS: Nine years of linked individual-level administrative data were utilised to examine changes in hospital-presenting self-harm and ideation (thoughts of self-harm or suicide) before and during the pandemic. METHOD: National self-harm registry data were linked to demographic and socioeconomic indicators from healthcare registration records ( n = 1 899 437)...

BACKGROUND: This narrative review aims to broaden our understanding of the epidemiology, burden and clinical spectrum of cluster headache based on updated findings with a global perspective. METHODS: We conducted a literature search on the following topics: (a) epidemiology; (b) burden: quality of life, disability, economic burden, job-related burden and suicidality; and (c) clinical spectrum: male predominance and its changes, age, pre-cluster and pre-attack symptoms, aura, post-drome, attack characteristics (location, severity, duration and associated symptoms), bout characteristics (attack frequency, bout duration and bout frequency), circadian and seasonal rhythmicity and disease course...

BACKGROUND: Mental health conditions and psychiatric disorders are among the leading causes of illness, disability, and death among young people around the globe. In the United States, teen suicide has increased by about 30% in the last decade. Raising awareness of warning signs and promoting access to mental health resources can help reduce suicide rates for at-risk youth. However, death by suicide remains a taboo topic for public discourse and societal intervention. An unconventional approach to address taboo topics in society is the use of popular media...

BACKGROUND: Google searches represent a snapshot of the world's interest in different topics and are reflected by Google Trends (GT). GT has gained recent popularity across various areas of healthcare research of interest to GPs, such as the seasonality of particular physical symptoms and population-level suicide risk. As a real-time data source, GT is appealing to healthcare researchers, but whether it has a place in primary care research remains largely unaddressed. AIM: To explore how GT can be used to research topics relating to primary care in order to evaluate its utility as a future research tool and inform primary care researchers and GPs on the uses and implications of GT as a research tool...

IMPORTANCE: The detection of seasonal patterns in suicidality should be of interest to clinicians and US public health officials, as intervention efforts can benefit by targeting periods of heightened risk. OBJECTIVES: To examine recent trends in suicidality rates, quantify the seasonality in suicidality, and demonstrate the disrupted seasonality patterns during the spring 2020 COVID-19-related school closures among US children and adolescents. DESIGN, SETTING, AND PARTICIPANTS: This population-based, descriptive cross-sectional study used administrative claims data from Optum's deidentifed Clinformatics Data Mart Database...

INTRODUCTION: During the pandemic years in Hungary, the completed suicide rates have risen significantly. Violent suicide attempts represent the majority of completed suicides. OBJECTIVE: In our study, we analyzed the change of the number of inpatients treated in Dr. Manninger Jenő National Traumatology Center between 2016 and 2021 due to violent suicide attempts, focusing on the trend in the first two years of the pandemic outbreak.

Circadian desynchronizations are associated with psychiatric disorders as well as with higher suicidal risk. Brown adipose tissue (BAT) is important in the regulation of body temperature and contributes to the homeostasis of the metabolic, cardiovascular, skeletal muscle or central nervous system. BAT is under neuronal, hormonal and immune control and secrets batokines: i.e., autocrine, paracrine and endocrine active substances. Moreover, BAT is involved in circadian system. Light, ambient temperature as well as exogen substances interact with BAT...

The COVID-19 pandemic has resulted in increased concern regarding the mental health of individuals navigating this public health crisis. Various risk factors for suicide have increased during the pandemic, including isolation, depression, access to firearms, substance use, and loss of employment. However, the relationship between the COVID-19 pandemic and suicide rates in the United States remains unclear. In this retrospective study, we examined the relationship between suicide rates and COVID-19 cases in 11 West Michigan counties...

This study will help in determining national suicide prevention strategies. Moreover, understanding the reasons for the lack of awareness about completed suicide will strengthen the measures to be taken in this regard. It was determined that the most important rate among the causes 48 419 completed suicide in Turkey in the years 2004 to 2019 was the 22 645 (46.76%) suicides of unknown cause and there was not enough information about the underlying causes. Suicide statistics data of the Turkish Statistical Institute (TUIK) between 2004 and 2019 were analyzed retrospectively in terms of geographical regions, gender, age groups and seasonality...

Objective: To review the current literature focusing on the most recent systematic reviews relating to mood, suicide, and psychiatric service utilization. Study Selection and Data Extraction: A systematic literature search of PubMed, CINAHL, and PsycINFO databases using the search terms "Systematic review" AND "season*" AND mood OR depression OR bipolar OR psychosis OR suicid* OR psychiatr* initially yielded 209 results. After screening by title and abstract for relevance, 6 records remained, while a further 3 were identified after screening of reference lists...

OBJECTIVE: Individuals with mental illnesses are exposed to an increased risk of suicide. In this study, we aimed to investigate the clinical characteristics and outcome of psychiatric patients who attempted suicide by drug overdose and required emergency care. METHODS: A retrospective study was carried out in the Department of Emergency, the First Affiliated Hospital, Zhejiang University School of Medicine. Electronic medical records of psychiatric patients who were hospitalized due to suicide attempts from March 2019 to February 2022, with a discharge diagnosis of drug overdose were reviewed...

BACKGROUND: Rampage mass shootings (RMS) are a subset of mass shootings occurring in public involving random victims. Due to rarity, RMS are not well-characterized. We aimed to compare RMS and NRMS. We hypothesized that RMS and NRMS would be significantly different with respect to time/season, location, demographics, victim number/fatality rate, victims being law enforcement, and firearm characteristics. STUDY DESIGN: Mass shootings (4 or more victims shot at a single event) from 2014-2018 were identified in the Gun Violence Archive (GVA)...

Decades of research have established seasonality effects on completed and attempted suicides, with rates increasing in spring. Little advancements have been made to explain this phenomenon, with most studies focusing almost exclusively on the number of suicide attempts and deaths. Using more than six years of data collected among a US, UK, and Canadian online community sample (N > 10,000), we used newly developed Prophet forecasting and autoregressive-integrated moving average time-series models to examine the temporal dynamics of explicit and implicit self-harm cognitions...

IMPORTANCE: National Hockey League (NHL) players are exposed to frequent head trauma. The long-term consequences of repetitive brain injury, especially for players who frequently engage in fighting, remains unknown. OBJECTIVE: To investigate the mortality rates and causes of death among NHL enforcers with more career fights and penalty minutes as compared with matched controls. DESIGN, SETTING, AND PARTICIPANTS: This matched cohort study examined 6039 NHL players who participated in at least 1 game in the seasons between October 11, 1967, and April 29, 2022, using official NHL data...

BACKGROUND: The COVID-19 pandemic led to increase in mental health problems and substance misuse. Yet, little is known about its impact on rates of deaths of despair (death by suicide and drug overdose). Our objective was to determine the impact of COVID-19 stay-at-home orders on deaths of despair using population-level data. We hypothesized that the longer duration of stay-at-home orders would increase rates of deaths of despair. METHODS: Utilizing quarterly suicide and drug-overdose mortality data from the National Center for Health Statistics from January 2019 through December 2020, we estimated fixed-effects models to examine the effects of the duration of stay-at-home orders as differentially implemented in 51 jurisdictions in the United States on each outcome...

Bipolar disorder (BD) is a common mental condition with a seasonal pattern (SP) of onset. In the spring, there is a higher incidence rate of mania or mixed onset and suicide. However, the underlying mechanism of this SP remains unclear. In this study, targeted metabolomics was used to understand metabolic changes in patients with BD before and after the spring equinox. Nine patients with BD and matched healthy controls were tested for serum metabolomics at the spring equinox and 15 days before and after the spring equinox...
