Adapting pediatric obesity care to better suit adolescent patients: Design of a treatment platform and results compared with standard care in the national patient quality register.

BACKGROUND: Obesity constitutes a critical risk for adolescent health. This study aimed at identifying youth-friendly components of obesity treatment. METHODS: In this feasibility study, an adolescent obesity treatment platform was implemented at two Pediatric outpatient clinics in Sweden. Body mass index (BMI), BMI z-score, and the category of obesity (International Obesity Task Force) were compared before and after the intervention and with data on standard care from the Swedish Childhood Obesity Treatment Register. RESULTS: The study included 99 participants (49 females) aged 13-18 years from 1 September 2014, to 31 December 2016. A pediatric nurse met the participants on average 6.5 times in the average inclusion period of 15 months. Physical activity sessions attracted 63 participants. Acceptance Commitment Therapy and In Real Life groups attracted 24 participants. At inclusion, 62 participants had obesity and 37 severe obesity, and 71/99 (72%) remained in the same category. The mean BMI increased from 32.0 to 33.4 kg/m2 (p < 0.01), but 56/94 (60%) participants lowered their BMI or increased less than 1 kg/m2 and 73% stayed to the end of the study. Participants who were new to treatment and participants coming for more than eight visits to the nurse did not increase in BMI. BMI did not change for the 221 out of 641 register patients who had two recordings of BMI in the study period. CONCLUSIONS: The platform was successful in increasing retention, and 60% of participants lowered or maintained their BMI. Still, seven out of ten adolescents with obesity or severe obesity remained in the same weight category.

Identification of Warning Signs During Selection of Surgical Trainees.

OBJECTIVE: The aim was to document empirical observations about antecedents to and practices of unsuitable behaviours amongst surgical trainees and develop an interview guide that could be used for the selection process. DESIGN: A mixed methods design was adopted combining a survey distributed to senior surgeons and heads of departments, followed by semi-structured interviews with experienced surgeons. SETTING: All surgical departments and hospitals in The South Swedish Health Care Region. PARTICIPANTS: The survey was completed by 54 of 83 eligible surgeons above 50years of age, and 4 of 7 heads of surgical departments. Semi-structured interviews with 13 surgeons representing local, regional, and university hospitals from the same cohort. RESULTS: Forty-six (85%) surgeons and four of seven heads of departments responded that they had come across surgical trainees deemed unsuitable to train and work as a surgeon. All heads of department and 31 of 54 of the surgeons believed tendencies towards unsuitability are evident early during training. From the survey, 107 statements described reasons for finding a trainee unsuitable. Qualitative analysis of the interviews and free-text answers of the survey led to identification of 11 problem domains with associated "warning signs". An interview guide to help detect unsuitability tendencies in candidates during selection procedures was constructed. CONCLUSIONS: Experienced surgeons have quite consistent views on what makes a person unsuitable as a surgeon. Their views have been systematized into 11 problem domains, and a set of 'warning signs' for unsuitable behaviours and traits has been developed. Early detection of these signs and traits is important for the individual, the work environment, and patient safety. A recommendation for a minimum framework for selection including the constructed interview guide is presented.

Virtual TeleRehab: a case study.

We examined the efficacy of a remotely based occupational therapy intervention. A 40-year-old woman who suffered a stroke participated in a telerehabilitation program. The intervention method is based on virtual reality gaming to enhance the training experience and to facilitate the relearning processes. The results indicate that Virtual TeleRehab is an effective method for motivational, economical, and practical reasons by combining game-based rehabilitation in the home with weekly distance meetings.

Application of artificial gel antibodies for investigating molecular polymorphisms of human pituitary growth hormone.

Artificial gel antibodies were used to investigate human growth hormone (GH) activity in preparations purified from human pituitary glands. A partially purified fraction containing differently sized structural variants of GH was processed to yield monomeric and dimeric forms suitable for synthesizing artificial polyacrylamide gel antibodies. These two types of GH antibodies were used for investigating GH activity in experiments using HPLC gel-permeation and ion-exchange chromatography. In the size-exclusion experiments, both hormone fractions eluted as homogeneous peaks, whereas the ion exchanger resolved the hormones into several active components. The GH monomer antibodies exhibited a much higher affinity for monomeric GH than for dimeric GH, and the GH dimer antibodies exhibited a much higher affinity for dimeric GH than for monomeric GH. It was concluded that these two sets of antibodies might be useful for discriminating between dimeric and monomeric GH in clinical samples.

Effects of intercept pathogen inactivation on platelet function as analysed by free oscillation rheometry.

INTRODUCTION: The Intercept Blood System, using InterSol as additive solution, is used for inactivation of contaminating pathogens in PCs, thus reducing the risk for transfusion transmitted infection and making it possible to prolong the storage period. This study aimed at investigating the ability of Intercept treated platelets to induce clot formation, as measured by coagulation time using free oscillation rheometry (FOR), and to compare with that of platelets in concentrates with the additive solution T-Sol or plasma. METHODS: Seventy-four single-donor platelet units were diluted in InterSol (n=27) or T-Sol (n=47) to a mean plasma concentration of 38%. The Intercept treatment was performed by addition of amotosalen HCl to the InterSol PCs followed by UVA irradiation and treatment with a compound adsorption device (CAD). Forty-six units were collected and stored in 100% plasma for comparison. Clotting time was measured by FOR in fresh PCs (within 26h after collection) after stimulation by a platelet activator. Soluble P-selectin was analysed as a marker of platelet activation in the Intercept and T-Sol PCs. RESULTS: The clotting time was shorter for Intercept treated platelets compared to platelets in T-Sol and plasma (p<0.05). There was no difference in clotting time between T-Sol and plasma PCs. Soluble P-selectin was higher for Intercept platelets than platelets in T-Sol (p<0.05). CONCLUSIONS: The platelets treated with the Intercept procedure had good clot promoting capacity.

Development of the Handy Bio-Strand and its application to genotyping of OPRM1 (A118G).

We previously developed a three-dimensional microarray system, the Bio-Strand, which exhibits advantages in automated DNA analysis in combination with our Magtration Technology. In the current study, we have developed a compact system for the Bio-Strand, the Handy Bio-Strand, which consists of several tools for the preparation of Bio-Strand Tip, hybridization, and detection. Using the Handy Bio-Strand, we performed single nucleotide polymorphism (SNP) genotyping of OPRM1 (A118G) by allele-specific oligonucleotide competitive hybridization (ASOCH). DNA fragments containing SNP sites were amplified from genomic DNA by PCR and then were fixed on a microporous nylon thread. Thus, prepared Bio-Strand Tip was hybridized with allele-specific Cy5 probes (<15mer), on which the SNP site was designed to be located in the center. By optimizing the amount of competitors, the selectivity of Cy5 probes increased without a drastic signal decrease. OPRM1 (A118G) genotypes of 23 human genomes prepared from whole blood samples were determined by ASOCH using the Handy Bio-Strand. The results were perfectly consistent with those determined by PCR direct sequencing. ASOCH using the Handy Bio-Strand would be a very simple and reliable method for SNP genotyping for small laboratories and hospitals.
