© 2020 Elsevier Ltd Sexting has been defined as sharing sexually suggestive content (i.e., sexts) via Internet or smartphone. To date, only a few studies investigated the role of personality traits in relation to sending or receiving sexts, and most of them used the Five Factor Model of Personality. No studies applied the theoretical model of HEXACO six personality traits (i.e., honesty-humility, emotionality, extraversion, agreeableness, conscientiousness, and openness to experience) when examining different types of sexting (i.e., sending own sexts, risky sexting, sharing sexts from someone else without his/her permission, sexting under pressure). Thus, this is the first study that, using a cross-cultural perspective, investigated HEXACO personality predictors of sexting behaviors considered as a multidimensional construct. A total of 5542 participants from 13 to 30 years old (Mage = 20.36; SDage = 3.67; 60.4% girls and 39.6% boys) from 10 different countries participated in the study. Participants completed the sexting behaviors questionnaire and the HEXACO personality inventory. Four hierarchical regression analyses were conducted to investigate which HEXACO personality traits predicted different sexting behaviors, controlling for country, biological sex, age, sexual identity status, and dating relationship status. Results showed that honesty-humility and conscientiousness were negatively predictive of all investigated sexting behaviors. Emotionality and extraversion were positively related, and agreeableness was negatively related to sending own sexts and risky sexting. Finally, openness to experience was negatively related to sharing sexts from someone else without his/her consent and sexting under pressure. Results have implications for the development and implementation of sexual education and prevention programs aimed towards adolescents and young adults.

© 2019 American Academy of Allergy, Asthma & Immunology Background: Mepolizumab is an anti–IL-5 antibody approved for the treatment of severe eosinophilic asthma. However, the prevalence of patients with severe asthma eligible for mepolizumab remains unknown, especially among children. Objective: To determine, in a population of patients with severe asthma from a tertiary referral center, the proportion of patients with an eosinophilic phenotype who would be eligible for mepolizumab, when stratified for the age of onset of asthma, and the prevalence of phenotypic features that favor mepolizumab therapy. Methods: An extensive database of 245 adults and children referred for severe asthma was used. The prevalence of severe asthma was estimated by using the European Respiratory Society/American Thoracic Society criteria. Patients with an eosinophilic uncontrolled phenotype qualified for mepolizumab. Results: In our cohort, 216 (88%) had severe asthma. Based on blood eosinophils of either greater than or equal to 150 cells/μL or greater than or equal to 300 cells/μL, 61%/41% had an eosinophilic phenotype, while 49%/34% were eligible for mepolizumab therapy. A greater percentage of adults (60%/47% of adults with asthma onset in adulthood [AoA] and 48%/26% adults with childhood-onset asthma [<18 years, CoA]) were eligible compared with children (33%/24%), for eosinophil counts of ≥150 and ≥300 cells/μL, respectively; P < .05. Compared with adults, children had a similar number of exacerbations while having better lung function (P < .05). Among adults, those with AoA were older, were more likely to have nasal polyps (28% vs 5%; P < .05), and had higher blood eosinophil counts (272 vs 150 cells/μL; P < .05) compared with those with CoA, with no difference in lung function noted between the 2 groups. Subjects showing greater than or equal to 500 eosinophils/μL, a strong indicator for mepolizumab therapy, had more nasal polyps, higher inhaled steroid dose, lower lung function, and AoA predominance than did those with less than 500 eosinophils/μL (P < .05). Conclusions: A smaller percentage of children with severe asthma were eligible for mepolizumab compared with their adult peers. Severe AoA has distinct phenotypic features that favor treatment with mepolizumab, including greater eosinophilia and nasal polyposis, in contrast to CoA, which appears to have fewer features of type 2 mucosal inflammation.

© 2018 Radboud University Medical Center Attention-deficit/hyperactivity disorder (ADHD) is highly heritable and the most common neurodevelopmental disorder in childhood. In recent decades, it has been appreciated that in a substantial number of cases the disorder does not remit in puberty, but persists into adulthood. Both in childhood and adulthood, ADHD is characterised by substantial comorbidity including substance use, depression, anxiety, and accidents. However, course and symptoms of the disorder and the comorbidities may fluctuate and change over time, and even age of onset in childhood has recently been questioned. Available evidence to date is poor and largely inconsistent with regard to the predictors of persistence versus remittance. Likewise, the development of comorbid disorders cannot be foreseen early on, hampering preventive measures. These facts call for a lifespan perspective on ADHD from childhood to old age. In this selective review, we summarise current knowledge of the long-term course of ADHD, with an emphasis on clinical symptom and cognitive trajectories, treatment effects over the lifespan, and the development of comorbidities. Also, we summarise current knowledge and important unresolved issues on biological factors underlying different ADHD trajectories. We conclude that a severe lack of knowledge on lifespan aspects in ADHD still exists for nearly every aspect reviewed. We encourage large-scale research efforts to overcome those knowledge gaps through appropriately granular longitudinal studies.

© Springer Nature Switzerland AG 2018. Video games are often seen as a reason for numerous psychological changes, both positive and negative, in players. For instance, many authors believe that video games push children and adults towards risky behaviors and impulsivity. The study aimed to analyze both theoretical and empirical evidences of that sort, as well as to investigate parameters of personal and cognitive impulsivity and risk-readiness in adult video gamers. The sample of gamers included 223 participants, all from Russia. Impulsivity and related personal traits were measured with Eysencks’ Impulsiveness Scale (I-7) and Kornilova’s Personal Risk Factors Questionnaire. Impulsivity as cognitive style was measured by Kagan’s MFFT. No evidence of high impulsivity was found, though video game players, who played more than 12 h per week turned out to be more venturesome, compared to less active gamers. Sex-related differences were investigated: female gamers scored lower in empathy, while male gamers showed higher venturesomeness. In a cognitive style study, video gamers were more accurate compared to non-gamers, and thus showed no tendency for impulsivity. The results are contrasted to the published data, when applicable.

Still's disease in children (systemic-onset juvenile idiopathic arthritis, SoJIA) and in adults (adult-onset Still's disease) are considered as non-familial systemic autoinflammatory diseases of unknown etiology driven by similar immunopathogenetic mechanisms. The adult-onset Still's disease pathogenesis is based on genetically determined innate immunity disturbances and molecular basis of immunopathogenesis consists of NLRP3 inflammasome-dependent mechanisms of inflammation characterized by hyperproduction of proinflammatory cytokines interleukin (IL) 1 and IL18. Nonsteroidal anti-inflammatory drugs, glucocorticoids, methotrexate and other disease modifying drugs are considered as «first line» medications for the treatment of adult-onset Still's disease and if they fail biologi-cals are recommended. A review of the literature data concerning anti-IL1 monoclonal antibodies administration in adult-onset Still's disease is presented, indicating good prospects for the use of canakinumab not only in case of resistance to standard therapy, but also as a «first-line» therapy in the onset of the disease.

The problem of childbearing in patients with myasthenia gravis (MG) is extremely important, since the disease most often affects women in the reproductive period. Has not yet been determined neither the prognostic criteria for myasthenia exacerbation during pregnancy, nor the predictors for the development of the transient neonatal myasthenia gravis (TNM). The article analyzes the literature data from the first descriptions of pregnancy in patients with myasthenia and TNM until the present days. The evolution of the concept of the role of a high titer of antibodies to acetylcholine receptors (anti-AChR Ab) in the development of exacerbations of MG in the mother and TNM in her newborn is shown. The role of Ab against γ-subunits of AChR in the development of arthrogryposis and THM is discussed. The importance of planning the pregnancy in myasthenic mothers is emphasized. These observations show that the same woman has either a favorable course of MG with the birth of a healthy child, or has a severe exacerbation until the postpartum myasthenic crisis with the birth of baby with TNM depending on quality of remission before pregnancy. Based on the literature data and own experience, the indisputable role of thymectomy in the prevention of exacerbations of MG and TNM is shown. Own observation of cases of TNM demonstrates the crucial role of neostigmine test in the recognizing of «floppy baby» syndrome. For the first time in Russia, a study of anti-fetal/anti-adult AChR Ab ratio in the umbilical cord blood was conducted. For the first time in the world, a unique case of the birth of a healthy child in a couple of patients with juvenile MG is presented. The husband suffering of the severe refractory MG with elevated titre of anti-AChR Ab up to 20.8 nmol/l and a lot of congenital stigmas of dysembryogenesis. The wife had a mild course of MG. She was carefully prepared for pregnancy by thymectomy and glucocorticoid-therapy and had a stable condition for more than 10 years at the time of pregnancy. The titer of anti-AChR Ab was relatively low (9.0 nmol/L), however, the pool of anti-AChR Ab in the umbilical cord blood mainly contained anti-fetal AChR AB (92%). This example shows that it is the quality of remission of the mother's MG at the time of pregnancy determines the course of the disease during pregnancy and the risks of TNM. This case allows us to consider genetic factors as secondary and once again emphasizes the autoimmune nature of myasthenia gravis.

© 2018 Interregional public organization Association of infectious disease specialists of Saint-Petersburg and Leningrad region (IPO AIDSSPbR). All rights reserved. Vaccination against pneumococcal infections by 13-va-lent conjugate vaccine (PCV13) can significantly reduce morbidity and mortality. The study has been aimed to evaluate the social and pharmacoeconomic aspects of PCV13 vaccination of 65-year-old patients with various risks of pneumococcal infection. Material and methods. Markov model with 5 and 15 years time horizon was used for the analysis from the position of the health care system. The analysis was carried out for 65-year-old citizens with low (absence of immunocompromized conditions and chronic diseases), moderate (patients with chronic diseases without immunodeficiency) and high (immunocompromized conditions) risk of pneumococcal infection as well as for the entire population of 65-year-old citizens, regardless of the risk level. In base-case assumption has been made that 1 dose of PCV13 should be administered for the patients from low and moderate risk groups and in the high-risk group 1 dose of PCV13 and in 8 weeks a dose of polysaccharide pneumococcal vaccine (PPV23) should be given. The treatment and physician visit costs have been calculated using CHI rates for St. Petersburg in 2018. Vaccination cost was calculated using the auction price to purchase PCV13 and PPV23 in 2018. Results. Vaccination of 1 cohort of 65-year-old citizens in Russian Federation within 5 years will result in prevention of 2200 deaths, 3900 cases of invasive pneumococcal diseases (IPD) and 48700 cases of community-acquired pneumonia. In 15 years prevention of about 4,3 thousand deaths, 6,6 thousand IPD and 101,1 thousand cases of CAP will be provided. Within 15-year horizon the cost-effectiveness ratio will be RUR 30,3, 82,4 and 410,0 thousand per QALY in high, moderate and low risk groups, respectively. Even if the time horizon is reduced to 5 years the PCV13 vaccination can be considered as an economically high-efficient intervention in moderate and high risk groups (cost-effectiveness ratio - RUR 279,2 and 221,7 thousand / QALY, respectively). In the 15-year-horizon noting the distribution of 65-year-olds by risk levels the cost-effectiveness ratio of PCV13 in population as a whole will be RUR 216,4 thousand / QALY. If moderate and high risk groups only are vaccinated, the average cost-effectiveness ratio will drop to RUR 67,6 thousand /QALY. At universal PCV13 vaccination of 65 years old in 5 year time horizon return of investment to the health care system budget will be 33.2% and at vaccination of persons with moderate and high risk return of investment will be 44.0%. With the assumption of vaccination during the planned physician visit (without additional visit) the return to the budget will be 46.8% and 60.9% for vaccination of all 65-year-olds and patients from the moderate and high risk groups, respectively. Conclusions. Vaccination of the 65-year-old persons against PCV13 pneumococcal infection in Russian Federation can be considered as a highly socially and economically effective intervention resulting in significant reduction of pneumococcal infection incidence and related mortality. The cost-effectiveness of vaccination is increasing along with the level of the risk. PCV13 vaccination of patients with moderate and high risk only provides a significant reduction in the burden for the health care budget in comparison with the vaccination of the entire population of 65-year-olds.
