ABSTRACT

This work presents a study on a new uranium iron arsenide UFe5As3. By implementing Bi-flux synthesis, we were able to grow mm-sized single crystals of this compound, which show twinning. UFe5As3 is one of only two known uranium iron arsenides. It adopts a monoclinic, UCr5P3-type crystal structure (space group P21/m, Pearson symbol mP18, a = 7.050(2) Å, b = 3.8582(9) Å, c = 9.634(1) Å, ß = 100.25(1)°). The magnetic susceptibility of UFe5As3 indicates it to be an antiferromagnet with TN = 47 K and µeff = 4.94 µB per formula unit, signaling that both U and Fe are likely magnetic in this material. The material appears to be anisotropic, with a small (likely ferromagnetic) spin reorientation transition around T = 29 K. The Sommerfeld coefficient γ0 = 135 mJ mol-1 K-2 suggests enhanced effective electron mass in UFe5As3, while electrical resistivity indicates metallic, Kondo-like behavior.

ABSTRACT

Nowadays, newborns that required prolonged respiratory maintenance for different reasons are more often surviving. Increase in the number of complications is observed on the background of positive clinical effects of certain component of intensive therapy. Search for the factors, which provoke appearance of recurrent bronchial obstruction syndrome, is an important component and basis of prophylaxis. The aim of our research was to conduct analysis of factors that provoke the development of recurrent bronchial obstruction syndrome. To build mathematical model of bronchial obstruction development in young children with respiratory disorders in neonatal period, the method of logistic regression was used. The results of conducted analysis enabled to detect that the presence of respiratory therapy significantly determines the risk of appearance of recurrent bronchial obstruction syndrome and suggest mathematical model of individual calculation of risk factors in this pathology. Data of conduction of mathematical analysis can be used for elaboration of a complex of rehabilitation measures concerning the development of recurrent bronchial obstruction syndrome in children, who suffered respiratory disorders in neonatal period. The highest risk of recurrent bronchial obstruction syndrome development in children born before 29 gestational week with simultaneous combination of prolonged (over 700 hours) total period of respiratory therapy. Elaborated method of individual calculation of the risk of recurrent bronchial obstruction syndrome development in young children, who experienced respiratory disorders in neonatal period, has practical significance and can be applied in everyday clinical practice.

ABSTRACT

AIM: To examine the challenges healthcare teams face when treating people with type 1 diabetes and disordered eating and the strategies these teams have developed to facilitate effective treatment. METHODS: Four semi-structured focus groups were conducted including two tertiary diabetes specialist teams and three tertiary eating disorders specialist teams between July and December 2018. Thematic analysis of the transcripts followed a six-phase process. RESULTS: Twenty-nine experienced healthcare professionals (16 diabetes and 13 eating disorder specialists, 16±12 years' professional experience) were interviewed. The challenges identified in treating people with type 1 diabetes and disordered eating included subthemes the 'challenges specific to the healthcare professional' (feeling not competent enough and perceived emotional burden), 'challenges pertaining to patient factors' (e.g. difficulties with engaging in therapy) and 'challenges created by the healthcare system' (time pressure and staff shortage). Healthcare professionals expressed the need for a consensus on diagnosis and the definition of disordered eating in type 1 diabetes, as well as the need for training and educational resources specific to type 1 diabetes and disordered eating. Healthcare professionals gave practical examples of strategies of communication for better patient engagement and felt that multidisciplinary working in joint clinics with the other specialty were facilitators for recovery from disordered eating. CONCLUSIONS: Healthcare professionals require multidisciplinary team support when treating people with type 1 diabetes and to improve their own competencies. The development of effective screening and assessment tools, educational resources and training for healthcare professionals, and developing multidisciplinary treatment pathways will be key to improving outcomes for their service users with type 1 diabetes and disordered eating.

ABSTRACT

Disordered eating is a serious and under-recognized problem in people with diabetes. This narrative review summarizes the research contributions made by psychological science over the past 25 years to the study of disordered eating in people with type 1 or type 2 diabetes, and identifies gaps and future directions relevant to both healthcare professionals and researchers. Key focus areas of psychological research investigating disordered eating in people with diabetes have been: (1) defining and classifying types of disordered eating; (2) identifying demographic, diabetes-specific and psychosocial correlates of disordered eating, and developing theoretical models of disordered eating in people with type 1 diabetes; (3) identifying the physical and psychosocial consequences of disordered eating; and (4) developing screening measures to identify disordered eating in people with type 1 diabetes. Psychological science has made significant contributions over the past 25 years to our understanding of the nature of this problem and the multiple factors which may interrelate with disordered eating in people with diabetes. Key areas for further attention include: (1) a better definition of disordered eating subtypes in people with type 1 diabetes; (2) characterizing disordered eating in people with type 2 diabetes; and (3) developing multidisciplinary, evidence-based prevention and treatment interventions for comorbid disordered eating and diabetes.

ABSTRACT

AIMS: To perform a qualitative review of online blogs authored by people self-identifying as having Type 1 diabetes and an eating disorder or 'diabulimia', a term used by people with Type 1 diabetes to describe an eating disorder that is characterized by deliberate restriction of insulin to control weight. METHODS: We conducted a structured qualitative review of online blogs published between 2012 and 2017 authored by people who report having Type 1 diabetes and an eating disorder or diabulimia. The subsequent thematic analysis followed a six-phase process and was conducted by two independent researchers. RESULTS: From 147 000 search results, 11 blogs (304 posts) matched criteria for further analyses. Three key themes and 18 subthemes emerged: 1) different aspects of bloggers' relationship with insulin, including motives for omitting insulin, secrecy of insulin omission and perception of control; 2) bloggers' experiences of diabetes complications, and diabetes ketoacidosis in particular, as well as their worries about future complications; 3) strategies for recovery and triggers for relapse, which involved diabetes self-management and setting up a support system. CONCLUSIONS: Qualitative analyses of blogs authored by people with Type 1 diabetes and an eating disorder or diabulimia have identified high levels of diabetes distress and provided insight into different motives for insulin omission and strategies for recovery. Considering the limited evidence for effective interventions, these findings may help the development of complex interventions to improve biomedical and psychological outcomes in this group.

ABSTRACT

HIV testing among substance abusers in the United States is a significant public and individual health issue in need of further examination. We analyzed interview data gathered over 15 months in 1992 and 1993 from 2315 patients on presentation for addiction treatment to determine the frequency of and factors associated with previous HIV testing. Among this group of alcohol, heroin, and cocaine abusers, 53% (1231) reported previous HIV testing. Although in bivariate and multivariable analyses those with identifiable risk factors for HIV were more likely to have been tested, 27% of injection drug users, 38% with multiple sexual partners, and 39% of those with a history of a sexually transmitted disease (STD) had not been HIV tested. Other factors associated with previous HIV testing included having a primary care physician, the primary care physician's awareness of the patient's substance abuse problem, and having received prior addiction care. However, 38% of substance abusers who had previously received addiction treatment beyond detoxification had not been tested. Of those tested, 10% (n = 122) reported a positive test, and 7% (n = 81) had not received the test results. Of those with positive test results, 37% were not injection drug users. Promotion of HIV testing among alcohol and other drug abusers in both medical and substance abuse treatment settings should be a priority.
