Among classic myeloproliferative neoplasms, essential thrombocythemia is associated with the greatest risk of venous thromboembolism during COVID-19.

In a multicenter European retrospective study including 162 patients with COVID-19 occurring in essential thrombocythemia (ET, n = 48), polycythemia vera (PV, n = 42), myelofibrosis (MF, n = 56), and prefibrotic myelofibrosis (pre-PMF, n = 16), 15 major thromboses (3 arterial and 12 venous) were registered in 14 patients, of whom all, but one, were receiving LMW-heparin prophylaxis. After adjustment for the competing risk of death, the cumulative incidence of arterial and venous thromboembolic events (VTE) reached 8.5% after 60 days follow-up.

Socio-Cultural Context and Bulling Others in Childhood.

The objective of this epidemiological study was to examine, using an ecological perspective, which individual and distal contextual factors (familial, social and cultural) are associated with bullying other children across two different sites. Our sample included 1,271 Puerto Rican children 10 and older years of age at baseline residing in the South Bronx in New York and in the Standard Metropolitan Area in San Juan and Caguas, Puerto Rico. Bullying others was assessed through parents' and children's response to one item in the conduct disorder section of the Diagnostic Interview Schedule for Children Version IV (DISC IV).

Psychiatric morbidity, functioning and quality of life in young people at clinical high risk for psychosis.

Objective: Recent studies suggest that psychotic-like experiences may also act as markers for non-psychotic psychiatric disorders, which may indicate that the focus of research in individuals at high risk (HR) for psychosis needs updating. In this study we thoroughly examined the clinical and functional characteristics of a consecutive cohort of young people at HR for psychosis and compared them to a matched sample of healthy volunteers.

Method: Between February 2010 and September 2012 60 help-seeking HR individuals, aged 16-35, were recruited from CAMEO Early Intervention in Psychosis Service, Cambridgeshire, UK.

Acculturation and drug use disorders among Hispanics in the U.S.

The authors' objective was to examine the relationship between degree of acculturation across five different dimensions of acculturation and risk of drug use disorders (DUD) among US Hispanics. Data were derived from a large national sample of the US adult population, the National Epidemiological Survey on Alcohol and Related Conditions, collected using face-to-face interviews.

Prevalence and correlates of child sexual abuse: a national study.

Background: This study examines the prevalence, correlates, and psychiatric disorders of adults with history of child sexual abuse (CSA).

Methods: Data were derived from a large national sample of the US population. More than 34000 adults 18 years and older residing in households were interviewed face-to-face in a survey conducted during the 2004-2005 period.

Course of comorbid anxiety disorders among adults with bipolar disorder in the U.S. population.

Objective: To examine the prevalence and correlates of comorbid anxiety disorders among individuals with bipolar disorders (BP) and their association with prospectively ascertained comorbidities, treatment, and psychosocial functioning.

Method: As part of the National Epidemiologic Survey on Alcohol and Related Conditions, 1600 adults who met lifetime DSM-IV criteria for BP-I (n = 1172) and BP-II (n = 428) were included. Individuals were evaluated using the Alcohol Use Disorder and Associated Disabilities Interview Schedule-DMS-IV Version and data was analyzed from Waves 1 and 2, approximately 3 years apart.

Psychostimulants for ADHD-like symptoms in individuals with autism spectrum disorders.

We conducted a comprehensive review of studies assessing the efficacy and tolerability of psychostimulants for ADHD-like symptoms in individuals with autism spectrum disorder (encompassing autism disorder, Asperger's syndrome and pervasive developmental disorders not otherwise specified). PubMed, Ovid, EMBASE, Web of Science, ERIC and CINHAL were searched through 3 January 2012. From a pool of 348 potentially relevant references, 12 citations (11 studies) were retained as pertinent.

Conduct disorder and adult psychiatric diagnoses: associations and gender differences in the U.S. adult population.

The authors' objective was to examine the presence of Axis I and II psychiatric disorders among adult males and females with a history in childhood and/or adolescence of conduct disorder (CD). Data were derived from a large national sample of the U.S.

Parental familism and antisocial behaviors: development, gender, and potential mechanisms.

Objective: To examine the relation between parental familism (strong values of attachment to nuclear and extended family members) and youth antisocial behaviors over time.

Method: Puerto Rican children 5 to 13 years of age at baseline residing in the South Bronx in New York (n = 1,138) and in the Standard Metropolitan Area in San Juan and Caguas, Puerto Rico (n = 1,353) were followed over two waves 1 year apart from 2000 to 2004. Parental familism was assessed using an adaptation of the Sabogal Familism Scale.
