RESUMEN
BACKGROUND: Liraglutide 3·0 mg was shown to reduce bodyweight and improve glucose metabolism after the 56-week period of this trial, one of four trials in the SCALE programme. In the 3-year assessment of the SCALE Obesity and Prediabetes trial we aimed to evaluate the proportion of individuals with prediabetes who were diagnosed with type 2 diabetes. METHODS: In this randomised, double-blind, placebo-controlled trial, adults with prediabetes and a body-mass index of at least 30 kg/m2, or at least 27 kg/m2 with comorbidities, were randomised 2:1, using a telephone or web-based system, to once-daily subcutaneous liraglutide 3·0 mg or matched placebo, as an adjunct to a reduced-calorie diet and increased physical activity. Time to diabetes onset by 160 weeks was the primary outcome, evaluated in all randomised treated individuals with at least one post-baseline assessment. The trial was conducted at 191 clinical research sites in 27 countries and is registered with ClinicalTrials.gov, number NCT01272219. FINDINGS: The study ran between June 1, 2011, and March 2, 2015. We randomly assigned 2254 patients to receive liraglutide (n=1505) or placebo (n=749). 1128 (50%) participants completed the study up to week 160, after withdrawal of 714 (47%) participants in the liraglutide group and 412 (55%) participants in the placebo group. By week 160, 26 (2%) of 1472 individuals in the liraglutide group versus 46 (6%) of 738 in the placebo group were diagnosed with diabetes while on treatment. The mean time from randomisation to diagnosis was 99 (SD 47) weeks for the 26 individuals in the liraglutide group versus 87 (47) weeks for the 46 individuals in the placebo group. Taking the different diagnosis frequencies between the treatment groups into account, the time to onset of diabetes over 160 weeks among all randomised individuals was 2·7 times longer with liraglutide than with placebo (95% CI 1·9 to 3·9, p<0·0001), corresponding with a hazard ratio of 0·21 (95% CI 0·13-0·34). Liraglutide induced greater weight loss than placebo at week 160 (-6·1 [SD 7·3] vs -1·9% [6·3]; estimated treatment difference -4·3%, 95% CI -4·9 to -3·7, p<0·0001). Serious adverse events were reported by 227 (15%) of 1501 randomised treated individuals in the liraglutide group versus 96 (13%) of 747 individuals in the placebo group. INTERPRETATION: In this trial, we provide results for 3 years of treatment, with the limitation that withdrawn individuals were not followed up after discontinuation. Liraglutide 3·0 mg might provide health benefits in terms of reduced risk of diabetes in individuals with obesity and prediabetes. FUNDING: Novo Nordisk, Denmark.

OBJECTIVES: Fixed-dose combination (FDC) therapy can improve outcomes in type 2 diabetes (T2D). We evaluated the bioequivalence of 2 doses of an FDC of extended-release metformin (metformin XR), empagliflozin, a sodium-glucose co-transporter 2 inhibitor, and linagliptin, a dipeptidyl peptidase-4 inhibitor, versus corresponding free tablet combinations. METHODS: Two randomized, open-label, two-way crossover studies in healthy adults compared: 2 FDC tablets of empagliflozin 5 mg/linagliptin 2.5 mg/metformin XR 1000 mg (Study 1; N = 30), 1 FDC tablet of empagliflozin 25 mg/linagliptin 5 mg/metformin XR 1000 mg (Study 2; N = 30) versus corresponding dose of free combinations. Subjects received study medication under fed conditions; washout was ≥35 days between treatments. Primary endpoints: area under the plasma concentration-time curve (AUC) from time 0 to last quantifiable data point for empagliflozin and metformin; AUC from time 0 to 72 hours for linagliptin, and peak plasma concentration (Cmax) for empagliflozin, linagliptin, and metformin. Bioequivalence was defined as adjusted geometric mean ratios (FDC: free combination) and two-sided 90% confidence intervals (CIs) of AUC and Cmax for each component within 80.00-125.00%. RESULTS: Study 1: 27/29 and 28/30 treated participants were included in the pharmacokinetic analysis for the FDC and free combination periods, respectively. Study 2: 29/29 treated participants were included in the pharmacokinetic analysis for both periods. The adjusted geometric mean ratios of FDCs to their respective free tablet combinations and two-sided 90% CIs were all within the predefined range. The shapes of the mean plasma concentration-time profile of empagliflozin, linagliptin, and metformin XR were similar for subjects in the FDC and free combination groups in both studies. No serious adverse events were reported. CONCLUSION: The evaluated doses of empagliflozin/linagliptin/metformin XR FDC tablets were bioequivalent to the corresponding free combinations. Based on these two bioequivalence studies and existing phase 3 data, the FDA has recently approved this triple FDC to improve glycemic control in adults with T2D.

Eliciting a weight history can provide clinically important information to aid in treatment decision-making. This view is consistent with the life course perspective of obesity and the aim of patient-centered care, one of six domains of health care quality. However, thus far, the value and practicality of including a weight history in the clinical assessment and treatment of patients with obesity have not been systematically explored. For these reasons, the Clinical Committee of The Obesity Society established a task force to review and assess the available evidence to address five key questions. It is concluded that weight history is an essential component of the medical history for patients presenting with overweight or obesity, and there are strong and emerging data that demonstrate the importance of life stage, duration of exposure to obesity, maximum BMI, and group-based trajectory modeling in predicting risk for increased morbidity and mortality. Consideration of these and other patient-specific factors may improve risk stratification and clinical decision-making for screening, counseling, and management. Recommendations are provided for the key elements that should be included in a weight history, and several needs for future clinical research are outlined.

A survey of 24 international heart valve banks was conducted to acquire information on heart valve processing techniques used and outcomes achieved. The objective was to provide an overview of heart valve banking activities for tissue bankers, tissue banking associations, and regulatory bodies worldwide. Despite similarities found for basic manufacturing processes, distinct differences in procedural details were also identified. The similarities included (1) use of sterile culture media for procedures, (2) antibiotic decontamination, (3) use of dimethyl sulfoxide (DMSO) as a cryoprotectant, (4) controlled rate freezing for cryopreservation, and (5) storage at ultralow temperatures of below -135°C. Differences in procedures included (1) type of sterile media used, (2) antibiotics combination, (3) temperature and duration used for bioburden reduction, (4) concentration of DMSO used for cryopreservation, and (5) storage duration for released allografts. For most banks, the primary reasons why allografts failed to meet release criteria were positive microbiological culture and abnormal morphology. On average, 85% of allografts meeting release criteria were implanted, with valve size and type being the main reasons why released allografts were not used clinically. The wide variation in percentage of allografts meeting release requirements, despite undergoing validated manufacturing procedures, justifies the need for regular review of important outcomes as cited in this paper, in order to encourage comparison and improvements in the HVBs' processes.
RESUMEN
There is great need for cost effective approaches to increase patient engagement and improve health and well-being. Health and wellness coaching has recently demonstrated great promise, but the majority of studies to date have focused on individual coaching (ie, one coach with one client). Newer initiatives are bringing a group coaching model from corporate leadership development and educational settings into the healthcare arena. A group approach potentially increases cost-effective access to a larger number of clients and brings the possible additional benefit of group support. This article highlights some of the group coaching approaches currently being conducted across the United States. The group coaching interventions included in this overview are offered by a variety of academic and private sector institutions, use both telephonic and in-person coaching, and are facilitated by professionally trained health and wellness coaches as well as trained peer coaches. Strengths and challenges experienced in these efforts are summarized, as are recommendations to address those challenges. A working definition of "Group Health and Wellness Coaching" is proposed, and important next steps for research and for the training of group coaches are presented.
Existe una gran necesidad de planteamientos económicamente rentables que incrementen el compromiso de los pacientes, y mejoren su salud y su bienestar. La formación de salud y bienestar ha demostrado recientemente ser muy prometedora, pero la mayoría de los estudios realizados hasta la fecha se han centrado en la formación individual (es decir, de un entrenador con un cliente). Existen iniciativas más recientes, procedentes del área de desarrollo del liderazgo empresarial y de entornos académicos, para trasladar modelos de formación en grupo al ámbito de la atención sanitaria. El abordaje en grupo podría proporcionar un acceso rentable a un mayor número de clientes, además de contar con la posible ventaja adicional del apoyo del grupo. En este artículo destacamos algunos de los planteamientos de formación en grupo que se están llevando a cabo en Estados Unidos. Las intervenciones de formación en grupo que incluimos en este resumen provienen de diversas instituciones académicas y privadas, utilizan la formación telefónica y presencial, y cuentan con el apoyo de monitores de salud y bienestar con formación profesional, así como de colegas entrenadores cualificados. Resumiremos los puntos fuertes y los retos a los que se enfrentan estas iniciativas, y se ofrecerán recomendaciones para abordar dichos desafíos. Se propondrá una definición operativa de "formación de grupos de salud y bienestar" y se mostrarán los próximos pasos importantes que deben seguir la investigación y la formación de monitores de grupos.
RESUMEN
PURPOSE: The purpose of this case study is to extend the understanding of leadership development in healthcare by documenting the impact of a systemic approach to developing frontline leaders in a large Canadian healthcare organization. DESIGN/METHODOLOGY/APPROACH: A total of 92 participants working in acute and community settings participated in an eight-day certificate program that combined classroom instruction, practical skill development, and applied projects. Program content was based on a learning needs assessment conducted with potential participants and their supervisors. FINDINGS: Frontline leaders and their supervisors rated the program positively in terms of its impact on participants' confidence and willingness to lead, awareness of leadership opportunities, communication, problem solving, response to conflict, and the ability to support their teams through change. It was also found, however, that supervisors' ratings were generally lower than those of participants. PRACTICAL IMPLICATIONS: Systemic approaches to leadership development offer healthcare the best chance of addressing the current leadership crisis. The challenge is finding innovative ways to demonstrate sustainable benefits in an industry that is struggling to address cost pressures. In the present study, personal and supervisor evaluations were used in conjunction with completion of applied change projects to demonstrate a tangible return on investment. ORIGINALITY/VALUE: Leadership can be learned and there is no better point of entry for development than those in frontline leadership positions. However, developing future leaders requires the commitment of an entire leadership community. Healthcare organizations that are experiencing leadership gaps must be prepared to make a long term investment if they want to achieve lasting healthcare reforms.

Single crystals have been obtained of xenobiotic reductase B (XenB), a flavoenzyme isolated and cloned from Pseudomonas fluorescens I-C. The enzyme catalyzes the NADPH-dependent elimination of nitrite from nitroglycerin with an approximately fivefold kinetic preference for the middle nitro group, primarily yielding 1,3-dinitroglycerol. X-ray diffraction data sets have been collected from native crystals to 2.3 A resolution. The space group is P4(1)2(1)2, with unit-cell parameters a = b = 140, c = 95.6 A. The asymmetric unit is likely to contain at least two XenB molecules (V(M) = 3.1 A(3) Da(-1), 60% solvent) and a molecular-replacement solution has been determined in order to solve the structure.

Residual dipolar couplings between 15N and 1H nuclear spins in HPr were used to determine the protein's orientation in a medium of bicelles, oriented by a magnetic field. In the case of wild-type HPr the protein's non-spherical shape can explain its orientation in this medium. In the case of the F48W mutant it was found that at least one other mechanism contributes to the observed orientation of the protein, to a degree that depends on the concentration of phosphate ions in the medium. We propose that the F48W mutant has a weak affinity towards the bicelle-surfaces that decreases with increasing phosphate concentrations. We used an order-parameter description to analyse this situation and to determine the axis of main order and the sign of the order parameter pertaining to this additional orientation mechanism.

Diffraction-quality crystals have been obtained of the xenobiotic reductase A (XenA) from Pseudomonas II-B, which was originally cultured from the contaminated soil of a World War II era munitions-manufacturing plant. Several complete X-ray diffraction data sets have been collected and analyzed. The native XenA data set includes reflections between 35 and 1.65 A. Four-wavelength MAD data sets from selenomethionine-enriched XenA and from three different ligand complexes are also reported. The XenA crystals belong to space group P2(1)2(1)2, with unit-cell parameters a = 84, b = 158, c = 57 A. Experimental phasing from analysis of the MAD data from selenomethionine-enriched XenA reveals the presence of two molecules in the asymmetric unit. They are related by a non-crystallographic 2(1) screw axis nearly parallel to the c axis, but offset by a quarter unit-cell translation. Thus, the local symmetry produces approximate systematic absences along the (00l) principal axis and complicates the space-group determination.
