Objective: Weight gain occurs during marriage, yet obesity treatment is focused on individuals. Outcomes may be improved by targeting joint weight loss and the interpersonal milieu that fosters spousal interdependence. Self-determination theory (SDT) posits that autonomy-supportive environments (e.g., promote meaningful choice, minimize control) produce better health outcomes. This trial tested an SDT-informed weight-loss intervention intended to facilitate autonomy support in couples.
Method: Sixty-four couples were randomized to standard behavioral weight loss (BWL) that couples attended together or to a SDT-informed weight-loss intervention (SDT-WL) that aimed to bolster autonomy support (AS). Groups met weekly for 6 months with assessments at 0, 3, 6, and 12 months.
Results: Percent weight loss at 6 and 12 months was 10.4% ± 6.5% and 9.2% ± 8.2%. No differences were observed between the BWL and SDT-WL conditions in percent weight loss or changes in AS. Across conditions, higher baseline AS predicted greater weight loss at 6 and 12 months (ps <.001). Increases in AS over time predicted greater weight loss at 6 and 12 months (ps ≤ .02). Post hoc moderation analysis indicated that only participants with low (but not high) baseline AS achieved greater gains in AS at 12 months in SDT-WL than in the BWL conditions (p < .02).
Conclusions: Although no differences were found between conditions on weight loss or changes in autonomy support behavior, autonomy support from one's spouse predicted weight loss in both couples-based weight-loss approaches. For couples with low levels of AS, an SDT-informed approach was effective at increasing this desirable interpersonal behavior. (PsycINFO Database Record (c) 2020 APA, all rights reserved).

This study assesses the impact of grape juice-based alginate or chitosan edible coatings, followed by UVC treatment, on the preservation of post-harvest quality of Red Globe grapes. Coated grapes were stored at 5 °C for 28 days, and their physical, chemical, microbiological, and sensory properties were assessed during the storage period. Films were prepared with grape juice using alginate and chitosan and exposed to 32.

Hydrogen peroxide (HO) was used to modify a natural polymer, sesbania gum (SG), to prepare oxidized sesbania gum (OSG) with the aim of investigating the physicochemical properties, antimicrobial activity of polyethylene oxide (PEO), OSG, and ε-poly(lysine) (ε-PL) composite fibre membranes and their applications in fresh-cut mango preservation. The PEO/OSG/ε-PL composite fibre membranes were successfully prepared via solution blow spinning (SBS) technology. The results of a series of characterizations revealed that ε-PL was successfully loaded into the fibrous membranes, exhibited good biocompatibility, and ε-PL was better encapsulated, with the membranes.

This study investigates the metabolic disruptions caused by nicotine (NIC) exposure, with a particular focus on amino acid and lipid metabolism, and evaluates resveratrol (RSV) as a potential protective agent. Mice were divided into four groups: control (CON), NIC-exposed, NIC + RSV-treated, and RSV-only. NIC exposure resulted in significant weight loss, elevated glucose levels, altered lipid profiles, and organ damage, particularly in the liver and kidneys.

Background: The INtensive diet versus Knee Arthroplasty (INKA) trial is a randomised trial assessing weight loss as an alternative to knee arthroplasty (KA) in obese patients with severe knee osteoarthritis (OA) awaiting KA (NCT05172843). The external validity of the INKA trial may be hampered if the patients who participate differ from those who decline participation.
Objective: To compare baseline characteristics between patients who enrol in the INKA trial and those who decline participation (i.

Objectives: The objective of this web-based study is to analyze the attributes of bariatric surgery cases ensuing health implications. Additionally, the study seeks to delve into the factors influencing post-bariatric psychological evaluations and the impact of various bariatric surgeries on weight loss and psycho-social assessment scores for patients who had undergone bariatric surgeries within a specific bariatric surgery center in Egypt between January 2017 and January 2024.
Methods: An analytical cross-sectional study recruited 411 adults who had undergone different bariatric procedures by the same surgical team.
