Objective: This study examined whether improvements in problem-solving abilities mediate the relation between treatment adherence and weight-loss outcome in the behavioral treatment of obesity.
Method: 272 women (mean+/-SD age=59.4+/-6.2 years, BMI=36.5+/-4.8) participated in a 6-month lifestyle intervention for obesity. Body weight and problem-solving skills (as measured by the Social Problem Solving Inventory-Revised) were assessed pre- and posttreatment. The completion of self-monitoring logs during the intervention served as the marker of treatment adherence.
Results: At posttreatment, participants lost 8.4+/-5.8 kg, an 8.8% reduction in body weight. Changes in weight were associated with increased problem-solving skills and with higher levels of treatment adherence. Improvements in problem-solving skills partially mediated the relation between treatment adherence and weight-loss outcome. Moreover, participants with weight reductions > or = 10% demonstrated significantly greater improvements in problem-solving skills than those with reductions <5%.
Discussion: Improvements in problem-solving skills may enable participants to overcome barriers to adherence and thereby enhance treatment-induced weight losses.

Real-world data on treatment outcomes or the quality of large-scale chronic hepatitis B (CHB) treatment programs in sub-Saharan Africa (SSA) is extremely difficult to obtain. In this study, we aimed to provide data on the prevalence and incidence of mortality, loss to follow-up (LFTU), and their associated factors in patients with CHB in three treatment centres in Eritrea. Additional information includes baseline clinical profiles of CHB patients initiated on nucleos(t)ide analogue (NUCs) along with a comparison of treatment with Tenofovir disoproxil fumarate (TDF) vs.

Non-alcoholic fatty liver disease (NAFLD) is a common hepatic manifestation of metabolic syndrome affecting 20-30 % of the adult population worldwide. This disease, which includes simple steatosis and non-alcoholic steatohepatitis, poses a significant risk for cardiovascular and metabolic diseases. Lifestyle modifications are crucial in the treatment of NAFLD; however, patient adherence remains challenging.

Background: The Minimum Information for Studies Evaluating Biologics in Orthopedics (MIBO) guidelines were developed in May 2017 to encourage improved reporting standards, promote increased transparency and reproducibility, and enhance clinical evaluation capabilities. The MIBO guidelines consist of 23 checklist items considered necessary to critically appraise clinical studies evaluating platelet-rich plasma (PRP).
Purpose: To assess randomized controlled trials that evaluated PRP for the treatment of knee osteoarthritis in order to systematically review their adherence to the MIBO guidelines.

Purpose: The purpose of this study was to use the advanced technique of Network Intervention Analysis (NIA) to investigate the trajectory of symptom change associated with the effects of self-control training on youth university students' chronic ego depletion aftereffects.
Methods: The nine nodes of chronic ego depletion aftereffects and integrated self-control training were taken as nodes in the network and analyzed using NIA. Networks were computed at the baseline, at the end of treatment, at 1-, 3-, 6-, 9- and 12-month follow up.
