High intake of cholesterol results in less atherogenic low-density lipoprotein particles in men and women independent of response classification

The influence of a high-cholesterol diet on the atherogenicity of the low-density lipoprotein (LDL) particle was examined by measuring LDL peak diameter and composition, LDL susceptibility to oxidation, and the distribution of cholesterol between LDL subclasses. The crossover intervention randomly assigned 27 premenopausal women and 25 men (18 to 50 years) to an egg (640 mg/d additional dietary cholesterol) or placebo (0 mg/d additional dietary cholesterol) diet for 30 days, followed by a 3-week washout period. Subjects were classified as either hyperresponders (>2.5 mg/dL increase in plasma cholesterol for each 100 mg additional dietary cholesterol consumed) or hyporesponders to dietary cholesterol. Sex was found to have a significant effect on 3 of the parameters examined. LDL peak diameter was significantly larger (P <.005) in females (26.78 +/- 0.59 nm, n = 27) as compared with males (26.52 +/- 0.49 nm, n = 25), regardless of response to dietary cholesterol. The LDL particles of the male participants also had a higher number of triglyceride (TG) and cholesteryl ester (CE) molecules (P <.01); however, cholesterol ester transfer protein (CETP) activity was higher in females (P <.05). Response classification also revealed significant differences in the determination of LDL subclasses. Independent of sex, the LDL-1 particle (P <.05), which is considered to be less atherogenic, was predominant in hyperresponders and this finding was associated with increased cholesterol intake (interactive effect, P <.001). In addition, CETP and lecithin: cholesterol acyltransferase (LCAT) activities were higher in hyperresponders during the egg period (interactive effect, P <.05). Sex, response to cholesterol intake, and diet were not found to affect the susceptibility of LDL to oxidation (P > 0.5). Because LDL peak diameter was not decreased and the larger LDL-1 subclass was greater in hyperresponders following egg intake, these data indicate that the consumption of a high-cholesterol diet does not negatively influence the atherogenicity of the LDL particle.     

Childhood Diabetes in the Nordic Countries: A Comparison of Quality Registries

Background:In 2008 a Nordic collaboration was established between the quality registries in Denmark, Iceland, Norway, and Sweden to improve quality of care for children with diabetes. This study aimed to describe those registries and confirm that the registry variables are comparable. Selected variables were used to demonstrate outcome measurements.Methods:The organization of the registries and methodology are described. Cross-sectional data for patients between birth and 14.9 years with type 1 diabetes mellitus in 2009 (n = 6523) from 89 centers were analyzed. Variables were age, gender, and diabetic ketoacidosis at onset, together with age, gender, HbA1c, insulin regimen, and severe hypoglycemia at follow-up in 2009.Results:All 4 registries use a standardized registration at the onset of diabetes and at follow-up, conducted at the local pediatric diabetes centers. Methods for measuring HbA1c varied as did methods of registration for factors such as hypoglycemia. No differences were found between the outcomes of the clinical variables at onset. Significant variations were found at follow-up for mean HbA1c, the proportion of children with HbA1c < 57 mmol/mol (NGSP/DCCT 7.4%), (range 15-31%), the proportion with insulin pumps (range 34-55%), and the numbers with severe hypoglycemia (range 5.6-8.3/100 patient years).Conclusions:In this large unselected population from 4 Nordic countries, a high proportion did not reach their treatment target, indicating a need to improve the quality of pediatric diabetes care. International collaboration is needed to develop and harmonize quality indicators and offers possibilities to study large geographic populations, identify problems, and share knowledge.     

One year follow-up of alcohol and illicit substance use in first-episode psychosis: Does gender matter?

Longitudinal studies on first-episode psychosis (FEP) patients have shown a decrease of substance use disorders (SUDs) over the first years of illness, but there has been less focus on the gender aspect. The present study examines stability of alcohol and illicit substance use, with specific focus on gender, in a one year follow-up investigation of 154 FEP patients (91 men, 63 women) in Oslo, Norway, using criteria for DSM-IV substance use disorder diagnosis, the Alcohol Use Disorders Identification Test (AUDIT) and the Drug Use Disorders Identification Test (DUDIT). The results show that cannabis was the most frequently used illicit substance at both times. Significantly more men (34%) than women (13%) had a current illicit SUD at baseline. At follow-up, the rate of illicit SUDs was significantly reduced in men (18%) but not in women (11%). There were no significant gender differences in the rate of current alcohol use disorders (AUD) (men 14%; women 8%) at baseline, and no significant reduction in AUD in any of the genders at follow-up. At follow-up, total AUDIT and DUDIT scores were reduced in men only. In conclusion, the high and persistent rate of SUDs, particularly of cannabis, among men and women during the first year of treatment for psychosis should be addressed in the clinical management of the patients. Female FEP patients who are also substance users may be particularly vulnerable in this regard and warrant closer attention.     

Launching into Adulthood from Institutional Care with a Serious Mental Health Condition

This qualitative study explores the experiences of emerging adults with serious mental health conditions (e.g., bipolar disorder, posttraumatic stress disorder) before and after they emancipate from the child welfare system and exit a transitional living program. Sixteen participants were interviewed before and 13 were interviewed after aging out. Findings suggest that transitional living programs services were appreciated for the relationships and safety net they fostered. Future plans were positive, but vague, and worries about the future were prevalent. Struggles with independence post-emancipation were common despite adult service use. Additional research is needed to understand how to best support these at-risk emerging adults.     

School-Related and Social–Emotional Outcomes of Providing Mental Health Services in Schools

This study evaluated student outcomes of an expanded school mental health (ESMH) model that placed community mental health clinicians on-site in schools to identify and treat children with mental health needs. The first aim of this study was to consider school-related outcomes (suspension rates and attendance rates) for those students who received ESMH treatment (n = 159) were compared to a matched high-risk sample that did not receive such services (n = 148). Results demonstrated differences between groups over time on measures of suspensions and attendance but not academic achievement. The second aim of this study was to evaluate change in social–emotional functioning (Strengths and Difficulties Questionnaire Scores) over time for the treatment group. Results indicated significant improvements on several parent and teacher ratings. Despite limitations of the ESMH framework examined in this study, the overall results suggest some promising advantages for students who received ESMH services.
