RESUMEN
BACKGROUND: The goal of the present study was to investigate the association between PTSD and the onset of hypertension in previously normotensive individuals in a population living in the stressful environment of the urban slums while controlling for risk factors for cardiovascular disease (CVD). METHODS: Participants were 320 normotensive individuals who lived in slums and were attending a family doctor program. Measurements included a questionnaire covering sociodemographic characteristics, clinical status and life habits, the Posttraumatic Stress Disorder Checklist - Civilian Version, and the Beck Depression Inventory. Incident hypertension was defined as the first occurrence at the follow-up review of the medical records of (1) systolic blood pressure of 140 mm Hg or higher or diastolic blood pressure of 90 mm Hg or higher, (2) the participant started taking antihypertensive medication, or (3) a new diagnosis of hypertension made by a physician. Differences in sociodemographic, clinical, and lifestyle characteristics between hypertensive and non-hypertensive individuals were compared using the χ2 and t tests. Multivariate Cox proportional hazards models were used to calculate hazard ratios (HR) and 95% confidence intervals (CI). RESULTS: Six variables - age, educational level, body mass, smoking, diabetes, and PTSD diagnosis - showed a statistically significant (p ≤ 0.20) association with the hypertensive status. In the Cox regression, only PTSD diagnosis was significantly associated with incident hypertension (multivariate HR = 1.94; 95% CI 1.11-3.40). CONCLUSIONS: The present findings highlight the importance of considering a diagnostic hypothesis of PTSD in the prevention and treatment of cardiovascular diseases.

This is a bibliometric analysis of the most-cited articles on post-traumatic stress disorder (PTSD) with the objective of identifying citation patterns for researchers, journals, centers, periods, topics, and nations. A search was conducted in Thomson Reuters' WoS Core Collection employing the expression TI = (posttraumatic stress disorder OR post-traumatic stress disorder OR PTSD). The 100 most-cited articles were downloaded, and the relevant data were extracted and analyzed. These studies had a total of 69,649 citations, ranging from a minimum of 360 to a maximum of 6029 citations, with an average of 696.49, a standard deviation of 720.92, mode of 369, and a median of 512. Eighty-eight percent of the most-cited articles on PTSD originated from the USA, with just six cities accounting for 52% of the publications and the Boston area alone responsible for almost one-fifth of the total output. The universities of Yale and Harvard headed the ranking of institutions with larger numbers of highly-cited articles. Female researchers represented 42.3% of all authors, 51% of the first authors, and 48% of the corresponding authors. The proportion of M.D. authors decreased significantly between the 1980-1999 (42%) and the 2000-2019 (27.2%) periods while that of Ph.D. authors increased from 44% to 57.4%. The most studied population was military veterans (28%). Female victims of sexual or physical violence, traumatized children, and adult survivors of childhood abuse were assessed in only 6-7% of the most-cited publications. Ten clinical trials evaluated psychological interventions but only three investigated pharmacotherapy. We concluded that influential research on PTSD remains centralized in the USA. A balanced gender representation in publications was found. There was a heavy reliance on combat veterans as the study population. Few highly-cited studies on the pharmacotherapy for PTSD were identified. Focused efforts are needed to address these challenges.
RESUMEN
It has been suggested in the medical literature that in the last period of his life King David (c. 1040-970 BCE) suffered from dementia, osteoporosis, hyperparathyroidism, Parkinson's disease, autonomic neuropathy, major depression, and malignancy. The goal of this study was to identify, based on the "Succession Narrative (SN)," a historically objective section of the Old Testament, the clinical syndrome presented by King David and to determine whether an impaired decision making capacity may have been manipulated by his courtiers to influence his succession's politics. The "SN" indicates that besides forgetfulness and trouble in thinking, King David suffered from marked cold intolerance and sexual dysfunction. The symptom triad consisting of cognitive impairment, cold intolerance, and sexual dysfunction is more strongly suggestive of hypothyroidism than of any other diagnoses proposed in the medical literature so far. We hypothesized that hypothyroidism was the underlying cause of the elderly King David's clinical picture and that his sometimes troubled thinking was successfully manipulated by the courtiers to favor his son Solomon's accession to the throne, with profound historical consequences.
RESUMEN
This study objective was to investigate publication trends on personality disorders (PD) and to identify patterns of historical development. Publication rates were determined using the Results by Year Timeline feature of PubMed. Time series autoregressive integrated moving average models were used to analyse the publication rates for PDs in quinquennial periods beginning in 1980 and ending in 2019 and to predict the number of publications in the 2024-2029 period. More than 300 articles on antisocial and borderline PD are being published each year, and the models suggest an accelerating growth rate. Approximately 100 articles are being published on average every year on schizotypal PD, and the regression model indicates linear growth in the near future. The mean number of publications per year for obsessive-compulsive, narcissistic and avoidant PDs is in the range of 10-30 with the corresponding models indicating linear growth. Fewer than 10 articles are being published each year on dependent, paranoid, histrionic and schizoid PD, whereas dependent PD shows modest growth and paranoid PD rates tended to stability, histrionic and schizoid PD exhibit declining rates. Personality disorders are a group of conditions with diverse etiological, prognostic, therapeutic, legal, research, social and cultural implications that influence publication rates.

Childhood abuse and PTSD are independently associated with severe psychiatric comorbidity. We hypothesized that among patients with adult-onset PTSD, a history of child abuse was associated with increased prevalence and severity of comorbid mental disorders. Participants were 109 adult treatment-seeking patients, 23.9% of whom had a history of childhood sexual, physical or emotional abuse. The socio-demographic characteristics and comorbidity profile of PTSD patients with and without history of child abuse were compared using the two-tailed t-test and the chi-square test. PTSD patients with a history of child abuse had significantly higher average PCL-C hyperarousal [21.8 (SDâ¯=â¯3.6) vs 19.8 (SDâ¯=â¯3.5)] and BDI [35.7 (SDâ¯=â¯9.2) vs 29.1 (SDâ¯=â¯13.9)] scores, a significantly increased average number of lifetime [4.85 (SDâ¯=â¯1.43) vs 3.93 (SDâ¯=â¯1.33)] and current [4.46 (SDâ¯=â¯1.24) vs 3.75 (SDâ¯=â¯1.32)] comorbid disorders, and a greater prevalence of lifetime (73.1% vs 44.6%) and current (79.2% vs 46.7%) panic disorder/agoraphobia and of psychotic symptoms (73.1% vs 30.1%). All effect sizes were in the medium to large range. Adult-onset PTSD patients with a history of child abuse may represent a subgroup with a more severe form of the disorder that is associated with a more serious clinical course, treatment resistance and poorer outcome.

OBJECTIVE: Bibliometrics is a group of statistical and mathematical methods employed to measure and analyze the quantity and the quality of scientific articles, books, and other forms of publications. The objective of the present study was to conduct a bibliometric analysis of the Jornal Brasileiro de Psiquiatria (JBP) by listing its 100 most highly cited articles in the scientific literature and identifying their main characteristics in terms of authorship and research topics and design. METHODS: The 100 topcited references in the JBP were identified through a search with Google Scholar. The main author, last author, corresponding author, the total number of authors, gender of the authors, year of publication, research institution, geographic origin, language, and the research design and subject of each reference were recorded and analyzed. RESULTS: A marked increase in the number of citations in the last 15 years, a relatively balanced distribution of publications among the Brazilian states and research centers, absence of gender bias among authors, and a varied range of published topics suggest a good current editorial performance by the JBP. Relative lack of systematic reviews and longitudinal studies, dearth of articles published in the English language, and modest participation of foreign authors were points requiring improvement. CONCLUSION: The present study suggests that a survey of the 100 most cited articles in the JBP can provide a historical overview of the progress of this journal, as well as highlight the main obstacles, constraints, and challenges faced by its editors and authors.
OBJETIVO: Bibliometria é um grupo de métodos estatísticos e matemáticos empregados para medir e analisar a quantidade e a qualidade de artigos científicos, livros e outras formas de publicações. O objetivo do presente estudo foi realizar uma análise bibliométrica do Jornal Brasileiro de Psiquiatria (JBP), relacionando seus 100 artigos mais citados na literatura científica e identificando suas principais características em termos de autoria e questões de pesquisa e delineamento experimental. MÉTODOS: As 100 referências mais citadas no JBP foram identificadas por meio de uma busca no Google Scholar. Foram registradas e analisadas as seguintes informações: autor principal, último autor, autor correspondente, número total de autores, gênero dos autores, ano de publicação, instituição de pesquisa, origem geográfica e idioma de cada referência e seu tema de investigação e delineamento metodológico. RESULTADOS: O aumento acentuado no número de citações nos últimos 15 anos, a boa distribuição das publicações entre os estados e centros de pesquisa brasileiros, a ausência de viés de gênero entre os autores e a variada gama de tópicos publicados sugerem um bom desempenho editorial atual do JBP. A relativa falta de revisões sistemáticas e estudos longitudinais, os poucos artigos publicados em inglês e a pequena participação de autores estrangeiros são pontos que requerem melhorias. CONCLUSÃO: O presente estudo sugere que o levantamento dos 100 artigos mais citados no JBP pode fornecer um panorama histórico da evolução dessa revista, bem como destacar os principais obstáculos, restrições e desafios enfrentados por seus editores e autores.
