Introduction Management of phenylketonuria (PKU) is mainly achieved through dietary control with limited intake of phenylalanine (Phe) from food, supplemented with low protein (LP) food and a mixture of free synthetic (FS) amino acids (AA) (FSAA). Casein glycomacropeptide (CGMP) is a natural peptide released in whey during cheese making by the action of the enzyme chymosin. Because CGMP in its pure form does not contain Phe, it is nutritionally suitable as a supplement in the diet for PKU when enriched with specific AAs. Lacprodan® CGMP-20 (= CGMP) used in this study contained only trace amounts of Phe due to minor presence of other proteins/peptides. Objective The aims were to address the following questions in a classical PKU mouse model: Study 1, off diet: Can pure CGMP or CGMP supplemented with Large Neutral Amino Acids (LNAA) as a supplement to normal diet significantly lower the content of Phe in the brain compared to a control group on normal diet, and does supplementation of selected LNAA results in significant lower brain Phe level?. Study 2, on diet: Does a combination of CGMP, essential (non-Phe) EAAs and LP diet, provide similar plasma and brain Phe levels, growth and behavioral skills as a formula which alone consist of FSAA, with a similar composition?. Material and methods 45 female mice homozygous for the Pahenu2 mutation were treated for 12 weeks in five different groups; G1(N-CGMP), fed on Normal (N) casein diet (75%) in combination with CGMP (25%); G2 (N-CGMP-LNAA), fed on Normal (N) casein diet (75%) in combination with CGMP (19,7%) and selected LNAA (5,3% Leu, Tyr and Trp); G3 (N), fed on normal casein diet (100%); G4 (CGMP-EAA-LP), fed on CGMP (70,4%) in combination with essential AA (19,6%) and LP diet; G5 (FSAA-LP), fed on FSAA (100%) and LP diet. The following parameters were measured during the treatment period: Plasma AA profiles including Phe and Tyr, growth, food and water intake and number of teeth cut. At the end of the treatment period, a body scan (fat and lean body mass) and a behavioral test (Barnes Maze) were performed. Finally, the brains were examined for content of Phe, Tyr, Trp, dopamine (DA), 3,4-dihydroxyphenylacetic acid (DOPAC), serotonin (5-HT) and 5-hydroxyindole-acetic acid (5-HIAA), and the bone density and bone mineral content were determined by dual-energy x-ray absorptiometry. Results Study 1: Mice off diet supplemented with CGMP (G1 (N-CGMP)) or supplemented with CGMP in combination with LNAA (G2 (N-CGMP-LNAA)) had significantly lower Phe in plasma and in the brain compared to mice fed only casein (G3 (N)). Extra LNAA (Tyr, Trp and Leu) to CGMP did not have any significant impact on Phe levels in the plasma and brain, but an increase in serotonin was measured in the brain of G2 mice compared to G1. Study 2: PKU mice fed with mixture of CGMP and EAA as supplement to LP diet (G4 (CGMP-EAA-LP)) demonstrated lower plasma-Phe levels but similar brain- Phe levels and growth as mice fed on an almost identical combination of FSAA (G5 (FSAA-LP)). Conclusion CGMP can be a relevant supplement for the treatment of PKU.

Abstract Background: Hepatitis B virus (HBV) remains a leading infectious cause of death worldwide, and is highly prevalent in Sub-Saharan Africa (SSA). The prevention of mother-to-child transmission (PMTCT) programs for HBV are critical to reaching elimination targets and utilizing existing HIV testing and treatment infrastructure. Building on a feasibility study to introduce tenofovir disoproxil fumarate antiviral therapy to pregnant women with high-risk HBV in the Democratic Republic of the Congo (DRC), we examine the social and psychological facilitators of medication adherence of women who participated in this HBV PMTCT program.Methods: This study utilizes a qualitative exploratory approach involving women in Kinshasa, DRC who were identified as high-risk HBV during pregnancy and completed the pilot tenofovir antiviral program. Six participants were identified and completed in-depth, open-ended phone interviews. This study adopts a modified Information-Motivation-Behavioral Skills model (IMB+) to identify emerging themes related to tenofovir adherence.Results: A strong trust in healthcare workers, family support, and improved awareness of the disease and treatment options through enrollment in the PMTCT program facilitated tenofovir adherence. Barriers to medication adherence included social stigma and low healthcare literacy specific to HBV.Conclusions: Our study highlights the feasibility of medication adherence in HBV PMTCT programs in a low-resource setting and the importance of incorporating initiatives that address hepatitis B stigma and other social barriers. These findings are relevant to future HBV PMTCT scale-up, which is needed in the DRC and in similar African contexts with high HBV prevalence. Trial registration: The parent study was registered with clinicaltrials.gov under identifier NCT03567382. Date of registration: 25/06/2018

IntroductionTo optimize type 1 diabetes mellitus self-management, experts recommend a person-centered approach, in which care is tailored to meet people’s needs and preferences. Existing tools for tailoring type 1 diabetes mellitus education and support are limited by narrow focus, lack of strong association with meaningful outcomes like A1c, or having been developed before widespread use of modern diabetes technology. To facilitate comprehensive, effective tailoring for today’s working-aged adults with type 1 diabetes mellitus, we developed and validated the Barriers and Supports Evaluation (BASES).Research design and methodsParticipants 25–64 years of age with type 1 diabetes mellitus were recruited from clinics and a population-based registry. Content analysis of semistructured interviews (n=33) yielded a pool of 136 items, further refined to 70 candidate items on a 5-point Likert scale through cognitive interviewing and piloting. To develop and validate the tool, factor analyses were applied to responses to candidate items (n=392). Additional survey data included demographics and the Diabetes-Specific Quality of Life (QOL) Scale-Revised. To evaluate concurrent validity, hemoglobin A1c (HbA1c) values and QOL scores were regressed on domain scores.ResultsFactor analyses yielded 5 domains encompassing 30 items: Learning Opportunities, Costs and Insurance, Family and Friends, Coping and Behavioral Skills, and Diabetes Provider Interactions. Models exhibited good to adequate fit (Comparative Fit Index >0.88 and Root Mean Squared Error of Approximation <0.06). All domains demonstrated significant associations with HbA1c and QOL in the expected direction, except Family and Friends. Coping and Behavioral Skills had the strongest associations with both HbA1c and QOL.ConclusionsThe BASES is a valid, comprehensive, person-centered tool that can tailor diabetes support and education to individuals’ needs in a modern practice environment, improving effectiveness and uptake of services. Clinicians could use the tool to uncover patient-specific barriers that limit success in achieving HbA1c goals and optimal QOL.

For a better understanding of the field of cognitive-behavioral therapy by children and adolescents, for studying and test of their own cognitions, for learning of alternative cognitive and behavioral skills, techniques and methods specifically adapted for them are used. It is possible for therapists working with children to create a wide range of cognitive-behavioral therapy materials that can be used flexibly depending on the child's needs and the nature of their problems. The article briefly reviews the essence and purposes of many such methods.

Asthma is one of the most common pediatric chronic physical conditions. Youth with comorbid asthma and anxiety/depressive symptoms tend to have less controlled asthma and an increased use of health services in schools. The purpose of this integrative review was to examine the literature on educational and behavioral/ cognitive behavioral skills interventions for children with asthma and anxiety/depressive symptoms. Five electronic databases and forward/backward citations were searched. Eleven peer reviewed articles were retained for review. Main findings of the limited evidence suggest that educational and behavioral/cognitive behavioral skills programs may increase asthma knowledge and asthma-related self-efficacy while reducing anxiety/depressive symptoms. One study showed a decrease in use of quick relief inhalers and another had increased adherence to asthma controller medication. The literature indicates that educational and cognitive behavioral skills programs can have a positive impact on children with asthma and symptoms of anxiety/depression. School-based skills programs had better retention than outpatient programs.
