Metabolic disorders in patients with chronic thromboembolic pulmonary hypertension

To analyze the relationship between metabolic disorders and obesity with hemodynamic parameters and the severity of the condition of patients with chronic thromboembolic pulmonary hypertension (CTEPH) based on the POLET register. The study included patients with CTEPH from the POLET register. Data from medical history, lipid profile, glycemia, uric acid level, weight, height, functional class (FC), distance in the 6-minute walk test (6MWT), echocardiography, and right heart catheterization were used for analysis. The study included 84 patients 60±14 years old, including 45 men. The majority of patients had FC III - 51 (65%), which corresponded to 6MWT - 338±113 m. Nineteen (23%) people had experience in taking PAH specific therapy, 37 (46%) had cardiovascular comorbidity. In the general group, the body mass index (BMI) was 25.7±4.5 kg/m2, and normal glycemia, lipid profile, and uric acid levels were also determined. mPAP was 51±12 mmHg, RA area was 25.5 (20; 30) cm2. Correlations were identified between: RA area and the level of total cholesterol (r=0.60; p<0.01), triglycerides (r=-0.24; p<0.001), LDL cholesterol (r=0.75; p=0.04), uric acid (r=0.75; p=0.03); total cholesterol and 6MWT (r=0.44; p=0.04). Analysis of metabolic disorders, FC and comorbidity revealed differences between FC III and IV groups in the level of HDL cholesterol (p=0.02) and triglycerides (p<0.01). The POLET registry includes mainly older patients. Severe FC (87% - III and IV) may be a result of the older age and the presence of concomitant pathology in almost half of the patients. The discovered relationships between the area of RA and FC with lipid and purine metabolism were discovered for the first time, however, they correspond to the direction of the world scientific researches, are important due to the use of these indicators in the scale for calculating the risk of death in patients with PAH and require further development.

A Review of the Child Anxiety Questionnaire Based on the Left-behind Children

Left-behind children are a special group in the process of urban development. They lack parental care, which affects the development of mental health. Anxiety is one of the most common psychological problems in children around the world. It has an important impact on children’s emotions and social interaction, lasting until adulthood. To study the anxiety of left-behind children, this study summarized the screening tools for children’s anxiety in this review and found that there is no anxiety questionnaire for left-behind children at present and most of the existing anxiety questionnaires for children are not completely based on the existing diagnostic criteria. As a result, these scales are not able to accurately measure all contents covered by the concept of children’s anxiety. The study summarized the left-behind anxiety questionnaire to provide some ideas for choosing a questionnaire for researchers studying left-behind children. In addition, the study believes that the development of anxiety scales for left-behind children as soon as possible and the use of multiple measurement methods should be the direction of future researchers.

Recidivism outcomes for young people who have committed a sexual offence and received treatment: A systematic narrative review of studies conducted in Australia and New Zealand

ABSTRACT Young people who have committed a sexual offence present unique and serious challenges to the criminal justice systems of Australia and New Zealand. To understand the current state of existing literature, we systematically collated and critically appraised studies using narrative synthesis, examining the recidivism outcomes of young people who have committed a sexual offence and received treatment. Eight studies were identified utilising a sample of 1528 young people. Recidivism was higher among participants who did not complete treatment, compared to those who completed treatment, but highest in those who commenced but subsequently “dropped out”. Our findings highlight a need for more Australian and New Zealand research addressing the recidivism rates post-treatment. More specifically, three future research directives are identified: the need for methodologically strong research, identification of recidivism outcomes for Indigenous young people, and the need for qualitative research to explore the profiles of young people who terminate treatment. PRACTICE IMPACT STATEMENT Our findings identified gaps in three key areas in current research within the Australian and New Zealand context: (1) a need for more methodologically strong evaluative research, (2) identification of recidivism outcomes for Indigenous young people, and (3) qualitative research to explore the profiles of young people who terminate treatment to compliment current research findings.

SUBJECT-OBJECT DIRECTION OF SCIENTIFIC RESEARCH IN THE FRAMEWORK OF THE PUBLIC ADMINISTRATION PROBLEMS: METHODOLOGICAL PROBLEMS OF FORMULATION AND WAYS TO SOLVE THEM

The article actualizes the methodological problem of specifying the directions of scientific researches in the specialty «Public Administration and Governance» in the third year of higher education. The relevant problem is considered through the prism of the absence of an officially approved standard of higher education at the educational and scientific level in the relevant specialty. Attention is drawn to the fact that the organization of scientific researches in the field of knowledge «Public Administration and Governance», in contrast to the researches carried out within the field of science «Public Administration» are carried out by applicants for the degree of Doctor of Philosophy without ensuring compliance of the content of qualification work with any directions of scientific research institutionalized at the state level. The article substantiates the fundamental difference between the methodological support of the applicant's choice of a scientific degree of subject-object direction of scientific research which is carried out in the field of knowledge «Public Administration and Governance» and in the field of science «Public Administration». Attention is drawn to the fact of absence of officially institutionalized at the state level for the field of knowledge «Public Administration and Governance» directions of organization of scientific research becomes the reason for actualization of risks of incorrect choice by the applicant for the degree «Doctor of Philosophy» of the focus of his scientific research. In contrast, a researcher who prepares a qualification work within the field of science «Public Administration», for example, the applicant for a doctoral degree in public administration, despite their conceptual maturity as a scientist, has a completely exhaustive list of research areas within the officially approved specialty passports. It is proposed to solve the problem of inconsistency of the researcher's previous research experience with the level of methodological support for the choice of the subject-object direction of scientific research through the prism of expanding (changing) the list of specialties within the field of knowledge «Public Administration and Management» and/or providing for separate specializations within the existing specialty. On the one hand, such a step, will allow to order the directions of scientific researches in accordance with the focus of attention of a particular field of knowledge, and on the other hand, it will contribute to improving of the quality of preparation and conducting of scientific research. The indirect result of expanding (changing) the list of specialties within the field of knowledge «Public Administration and Governance» may be its further development, for example, in the direction of ensuring correlation with the field of science «Public Administration».

Airborne Exposure to Pollutants and Mental Health: A Review with Implications for United States Veterans.

Inhalation of airborne pollutants in the natural and built environment is ubiquitous; yet, exposures are different across a lifespan and unique to individuals. Here, we reviewed the connections between mental health outcomes from airborne pollutant exposures, the biological inflammatory mechanisms, and provide future directions for researchers and policy makers. The current state of knowledge is discussed on associations between mental health outcomes and Clean Air Act criteria pollutants, traffic-related air pollutants, pesticides, heavy metals, jet fuel, and burn pits. Although associations between airborne pollutants and negative physical health outcomes have been a topic of previous investigations, work highlighting associations between exposures and psychological health is only starting to emerge. Research on criteria pollutants and mental health outcomes has the most robust results to date, followed by traffic-related air pollutants, and then pesticides. In contrast, scarce mental health research has been conducted on exposure to heavy metals, jet fuel, and burn pits. Specific cohorts of individuals, such as United States military members and in-turn, Veterans, often have unique histories of exposures, including service-related exposures to aircraft (e.g. jet fuels) and burn pits. Research focused on Veterans and other individuals with an increased likelihood of exposure and higher vulnerability to negative mental health outcomes is needed. Future research will facilitate knowledge aimed at both prevention and intervention to improve physical and mental health among military personnel, Veterans, and other at-risk individuals.
