Background: In Russia, physicians are virtually unaware of drugs based on needle extract. However, abroad, saponins and, in particular, a combined preparation containing needle extract, hesperidin and vitamin C is one of drugs of choice, if not the leading medication in treatment of venous oedemas and other venous symptoms.

Aim: The authors conducted a systematic review of the Russian-and English-language literature using the following search terms: saponins, hesperidin, needle, ruscus, ruscogenin (and their Russian equivalents), each of which was entered in a combination with the word 'venous' or its Russian equivalent, respectively.

This randomized trial tested the impact of an established prevention program for first-time parents, Family Foundations, adapted for low-income mothers and fathers as a series of sessions provided to couples in their homes. To assess program impact, we recruited and randomly assigned a sample of 150 low-income adult mother-father dyads (not necessarily still romantically involved, cohabiting, or married) during pregnancy or shortly after birth. The randomly assigned intervention families participated in Family Foundations Home Visiting (FFHV), consisting of 11 in-home sessions focusing on parental cooperation, collaboration, and conflict management to support children's development.

Indirect aggression has been associated with antisocial personality traits like Machiavellianism, but there is a lack of evidence on their longitudinal development across adolescence. Therefore, the joint developmental trajectories of adolescent indirect aggression and Machiavellianism across 3 years of high school (Grades 10 to 12) were investigated. Predictors of joint trajectory groups at the start of high school (Grade 9) were also explored. Read More

Objective: Childhood onset aggression can cause major suffering to affected families and is associated with many negative outcomes in the child's later life, including poor academic performance, adolescent delinquency, drug abuse, depression and antisocial personality disorder. Currently available prevention and intervention strategies have limited efficacy, but a better understanding of underlying genetic and neurobiological factors can lead to more effective prevention and treatment strategies, through genetic screening programs and novel therapies.

Method: This study examined the RS1 (n = 299 aggression, n = 192 controls) and RS3 (n = 291 aggression, n = 189 controls) microsatellite repeats within the promoter region of the vasopressin receptor 1A gene (AVPR1A) and their association with extreme childhood aggression, as assessed by the Child Behavior Checklist (CBCL), as well as the Teacher Report Form (TRF) and Youth Self Report (YSR).

Importance: Altered functional connectivity (FC) is a common finding in resting-state functional magnetic resonance imaging (rs-fMRI) studies of people with psychosis, yet how FC disturbances evolve in the early stages of illness, and how antipsychotic treatment influences these disturbances, remains unknown.

Objective: To investigate longitudinal FC changes in antipsychotic-naive and antipsychotic-treated patients with first-episode psychosis (FEP).

Design, Setting, And Participants: This secondary analysis of a triple-blind, randomized clinical trial was conducted over a 5-year recruitment period between April 2008 and December 2016 with 59 antipsychotic-naive patients with FEP receiving either a second-generation antipsychotic or a placebo pill over a treatment period of 6 months.

The literature has shown a strong correlation between victimization and violence. As the majority of treatment programs for violence and the associated research have been focused on men, it is vital that services are also oriented to the needs of women who perpetrate violence. () was developed to fill the gap in violence prevention programming for justice-involved women with histories of violence victimization and perpetration. Read More

The assumed evolutionary advantage of dominance is increased reproductive success. However, the efficacy of dominance as a mating strategy may be interrupted by any number of variables including female choice, estrous synchrony, and mating by non-troop males. In Japanese macaques (Macaca fuscata), there is evidence both for and against dominance as conferring reproductive success for adult males, with many discussions pointing to the importance of female choice in governing reproductive success in certain populations.

Aims: Venue capacity has been proposed as a factor associated with a greater number of violent incidents on-premises, though no specific research has demonstrated this association, and instead has tended to focus on the relationship between crowding and aggression. The aim of this report is to investigate the association between venue capacity and the number of violent incidents on-premises.

Methods: Venue capacity data (the maximum capacity listed on the liquor license) were obtained for all venues in central Melbourne from 2010 until 2016. Read More

Long-term outcomes of childhood bullying perpetration have been explored, but heterogeneity in outcomes reflecting nonclinical antisocial tendencies including indirect aggression, psychopathic personality, and interpersonal relations have not been examined from a person-centered approach. Accordingly, latent class growth analyses were used to examine trajectory groups of childhood bullying perpetration across ages 10 to 18 and multi-trajectory groups of young adulthood outcomes across ages 19 to 23 (indirect aggression, psychopathic personality, interpersonal relations). In a sample of 701 participants (52. Read More

Despite putative gender differences in the expression of narcissism, prominent theories have virtually dismissed the role of females in the development and manifestation of narcissism. The contention that narcissism is a pathology of the self that may partly differ in males and females is further evident in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). The DSM-5 reports that up to 75% of those diagnosed with Narcissistic Personality Disorder (NPD) are men. Read More

Aggression is a fundamental behavior displayed universally among animal species, but hyper- or hypo-aggressiveness can be maladaptive with negative consequences for individuals and group members. While the social and ecological significance of aggression is well understood, the specific neurobiological and hormonal mechanisms responsible for mediating aggression have not been fully elucidated. Previous studies have shown a relationship between aggressive acts and circulating gonadal steroids, but whether classical nuclear steroid receptors regulate aggression in animals is still uncertain.

Technologies have become important for interaction in couples. However, in some cases, controlling and aggressive behaviors can occur in the context of virtual interactions in couples; this is known as cyber-dating abuse (CDA). Identifying factors linked to CDA, as perpetrator and victim, are relevant for its prevention; therefore, more research is needed in this novel field of study. Read More

The social ants, bees, wasps, and termites include some of the most ecologically-successful groups of animal species. Their dominance in most terrestrial environments is attributed to their social lifestyle, which enable their colonies to exploit environmental resources with remarkable efficiency. One key attribute of social insect colonies is the division of labour that emerges among the sterile workers, which represent the majority of colony members. Read More

The relationship between anabolic-androgenic steroid (AAS) use and aggression and psychological distress requires further elucidation. No previous study has examined whether the latent patterns of aggression and psychological distress are the same in male and female AAS users. Multigroup latent class analysis (MLCA) can be used to classify individuals into groups based on their responses on a set of variables, and to investigate measurement invariance across subgroups.

Recent research has demonstrated that toddlers expect individuals to approach and reward those who defend a victim from an aggressor rather than those who refuse to do so. This work focused on toddlers' expectations of corporal third-party punishments trought various actions, such as hitting with a stick or repelling someone who refused to defend a social partner following aggression. Using a violation of expectation paradigm (VoE), three experiments were carried out to investigate whether 21-month-olds expect others to apply different kinds of corporal punishments against the non-defender puppet (expected event) rather than the defender puppet (unexpected event), showing a bystander hitting with a stick (Experiment 1) or pushing strongly (Experiment 3) each of the two puppets.
