RESUMO
PURPOSE: The focus of measuring success in obesity treatment is shifting from weight loss to patients' health and quality of life. The objective of this study was to select a core set of patient-reported outcomes and patient-reported outcome measures to be used in clinical obesity care. MATERIALS AND METHODS: The Standardizing Quality of Life in Obesity Treatment III, face-to-face hybrid consensus meeting, including people living with obesity as well as healthcare providers, was held in Maastricht, the Netherlands, in 2022. It was preceded by two prior multinational consensus meetings and a systematic review. RESULTS: The meeting was attended by 27 participants, representing twelve countries from five continents. The participants included healthcare providers, such as surgeons, endocrinologists, dietitians, psychologists, researchers, and people living with obesity, most of whom were involved in patient representative networks. Three patient-reported outcome measures (patient-reported outcomes) were selected: the Impact of Weight on Quality of Life-Lite (self-esteem) measure, the BODY-Q (physical function, physical symptoms, psychological function, social function, eating behavior, and body image), and the Quality of Life for Obesity Surgery questionnaire (excess skin). No patient-reported outcome measure was selected for stigma. CONCLUSION: A core set of patient-reported outcomes and patient-reported outcome measures for measuring quality of life in clinical obesity care is established incorporating patients' and experts' opinions. This set should be used as a minimum for measuring quality of life in routine clinical practice. It is essential that individual patient-reported outcome measure scores are shared with people living with obesity in order to enhance patient engagement and shared decision-making.

The advent of mobile smartphones and similar technology has opened new opportunities for studying human mobility within psychology and companion disciplines such as human geography, demography, and sociology. This article examines how such research raises novel ethical concerns. To do so, we outline two research projects: one based in Northern Ireland (The Belfast Mobility Project) and the other in Chile (The Norm-Contact Mobility Project), drawing concrete examples of the ethical challenges encountered throughout both projects, which used global navigational satellite systems as a tool for data collection. We discuss new threats to participant confidentiality and anonymity, problems of "unanticipated" data collection and exploitation, emerging difficulties in achieving properly informed consent, and concerns regarding the representation of vulnerable populations with limited access to smartphones and a legitimate fear of surveillance. We also reflect on the different measures we took to tackle these challenges and discuss the importance of implementing wider changes in the protocols associated with basic ethical research principles.

BACKGROUND: Melanoma disease patterns vary with patient age. AIM: To evaluate sentinel lymph node biopsy (SLNB) in managing melanoma at differing patient ages. METHODS: Online prediction tools were applied to compare SLNB positivity (SLNB+) and survival risk at patient ages 20-80. Tübingen melanoma data were used to determine variations in the hazard ratio of SLNB+ for mortality at different patient ages. RESULTS: Regardless of tumour thickness, predicted SLNB+ rates were markedly higher than mortality rates for 20-year-old patients. For 80-year-old patients, it is the opposite. DISCUSSION: If 1000 20-year-olds with a 0.4 mm thickness non-ulcerated melanoma underwent SLNB, 100 would likely be positive. If all 100 were to be offered adjuvant drug therapy (ADT), fewer than three more melanoma deaths in those 1000 patients would be avoided. In total, 97 patients would have received medication they may never have needed. If 1000 80-year-olds with a 3 mm thickness non-ulcerated melanoma underwent SLNB, only 40 would likely be positive. In total, 274 patients would be predicted to die of melanoma, 245 being SLNB negative and 29 SLNB+. ADT linked to SLNB+ could deny treatment to 89% of these high-risk patients. LIMITATIONS: The authors relied on published risk data. CONCLUSION: SLNB has poor specificity at predicting mortality in young melanoma patients and poor sensitivity in older patients. SLNB is not indicated in managing cutaneous melanoma for patients under 40 or over 60 years of age. Many such patients could be managed with wide local excision alone in their clinician's office-based practice. For all cutaneous melanoma patients at all ages, linking ADT to BAUSSS biomarker, (an algorithm of Breslow thickness, age, ulceration, subtype, sex and Site) rather than SLNB+ is likely more appropriate. BAUSSS provides a more accurate melanoma-specific mortality risk assessment for patients without burdening them with added surgery, hospitalization, costs or morbidity risk.

Research on the contact hypothesis has traditionally prioritized the role of positive, direct, face-to-face interactions in shaping intergroup prejudices, but it has recently expanded to study indirect vicarious, negative, and online contact experiences. In the majority of studies though, there has been little direct comparison of the relationship between these different forms of contact and prejudice. The present research set out to compare the amount and effects of negative, online, and vicarious contact in the context of positive, face-to-face and direct contact in two studies. Study 1 comprised a national cross-sectional survey of relations between White and Black UK residents (n = 1014), and Study 2 comprised a national longitudinal survey of relations between Catholic and Protestant residents of Northern Ireland (n = 1030). The results of both studies indicated that positive face-to-face contact occurred more frequently and had a comparatively stronger relationship with prejudice than other forms of contact. However, they also indicated the effects of online, negative and vicarious forms of contact existed independently of those of direct, positive face-to-face contact. Moreover, online negative contact generally had a stronger relationship to prejudice than negative contact experienced face-to-face. Exploratory mediation analyses suggested the affective pathways from contact to prejudice may vary for different forms of contact.

BACKGROUND: This network meta-analysis aimed to compare the effects of bariatric surgery, novel glucose-lowering agents (SGLT2i, GLP1RA, DPP4i), and insulin for patients with type 2 diabetes mellitus (T2DM) and obesity. METHODS: Four databases were searched from inception to April 2023 to identify randomized controlled trials (RCTs) comparing bariatric surgery, SGLT2i, GLP1RA, DPP4i, insulin, and/or placebo/usual care among patients with T2DM and obesity in the achievement of HbA1c < 7.0 per cent within one year, and 12-month changes in HbA1c and body weight. RESULTS: A total of 376 eligible RCTs (149 824 patients) were analysed. Bariatric surgery had significantly higher rates of achieving HbA1c < 7.0 per cent than SGLT2i (RR = 2.46, 95 per cent c.i. = 1.28, 4.92), DPP4i (RR = 2.59, 95 per cent c.i. = 1.36, 5.13), insulin (RR = 2.27, 95 per cent c.i. = 1.18, 4.58) and placebo/usual care (RR = 4.02, 95 per cent c.i. = 2.13, 7.93), but had no statistically significant difference from GLP1RA (RR = 1.73, 95 per cent c.i. = 0.91, 3.44), regardless of oral (RR = 1.33, 95 per cent c.i. = 0.66, 2.79) or injectable (RR = 1.75, 95 per cent c.i. = 0.92, 3.45) administration. Significantly more GLP1RA patients achieved HbA1c < 7.0 per cent than other non-surgical treatments. Bariatric surgery had the greatest reductions in HbA1c (â¼1 per cent more) and body weight (â¼15â kg more) at 12 months. Among novel glucose-lowering medications, GLP1RA was associated with greater reductions in HbA1c than SGLT2i (-0.39 per cent, 95 per cent c.i. = -0.55, -0.22) and DPP4i (-0.51 per cent, 95 per cent c.i. = -0.64, -0.39) at 12 months, while GLP1RA (-1.74â kg, 95 per cent c.i. = -2.48, -1.01) and SGLT2i (-2.23â kg, 95 per cent c.i. = -3.07, -1.39) showed greater reductions in body weight than DPP4i at 12 months. CONCLUSION: Bariatric surgery showed superiority in glycaemic control and weight management compared to non-surgical approaches. GLP1RA administered by oral or injectable form demonstrated reduced HbA1c and body weight at 12 months, and was preferable over other non-surgical treatments among patients with T2DM and obesity.

People with chronic obstructive pulmonary disease (COPD) have a higher prevalence of pain and a greater risk of falls than their healthy peers. As pain has been associated with an increased risk of falls in older adults, this study investigated the association between pain and falls in people with COPD compared to healthy controls. Data from the English Longitudinal Study of Ageing were used to establish an association between pain and falls when modelled with a generalised ordinal logistic regression and adjusted for sex, age, wealth, and education (complete case analysis only; n = 806 COPD, n = 3898 healthy controls). The odds were then converted to the predicted probabilities of falling. The predicted probability of falling for people with COPD was greater across all pain categories than for healthy controls; for COPD with (predicted probability % [95%CI]), no pain was 20% [17 to 25], with mild pain was 28% [18 to 38], with moderate pain was 28% [22 to 34] with severe pain was 39% [30 to 47] and for healthy controls with no pain was 17% [16 to 18], mild pain 22% [18 to 27], moderate pain 25% [20 to 29] and severe pain 27% [20 to 35]. The probability of falling increased across pain categories in individuals with COPD, with the most severe pain category at a nearly 40% probability of falling, indicating a potential interaction between COPD and pain.

PURPOSE: Bariatric and metabolic surgery is an effective treatment for severe and complex obesity; however, robust long-term data comparing operations is lacking. Clinical registries complement clinical trials in contributing to this evidence base. Agreement on standard data for bariatric registries is needed to facilitate comparisons. This study developed a Core Registry Set (CRS) - core data to include in bariatric surgery registries globally. MATERIALS AND METHODS: Relevant items were identified from a bariatric surgery research core outcome set, a registry data dictionary project, systematic literature searches, and a patient advisory group. This comprehensive list informed a questionnaire for a two-round Delphi survey with international health professionals. Participants rated each item's importance and received anonymized feedback in round 2. Using pre-defined criteria, items were then categorized for voting at a consensus meeting to agree the CRS. RESULTS: Items identified from all sources were grouped into 97 questionnaire items. Professionals (n = 272) from 56 countries participated in the round 1 survey of which 45% responded to round 2. Twenty-four professionals from 13 countries participated in the consensus meeting. Twelve items were voted into the CRS including demographic and bariatric procedure information, effectiveness, and safety outcomes. CONCLUSION: This CRS is the first step towards unifying bariatric surgery registries internationally. We recommend the CRS is included as a minimum dataset in all bariatric registries worldwide. Adoption of the CRS will enable meaningful international comparisons of bariatric operations. Future work will agree definitions and measures for the CRS including incorporating quality-of-life measures defined in a parallel project.

PURPOSE: To investigate the immediate effects of wearing novel sensory-stimulating textured insoles on balance and gait in 41 people with multiple sclerosis (pwMS). MATERIALS AND METHODS: Assessments of balance (firm/foam surface; eyes open/closed) and walking (when negotiating even/uneven surfaces) were performed wearing textured insoles, smooth insoles, shoes only, and barefoot. Outcome measures were centre of pressure (CoP) movement during standing (elliptical area, sway path velocity) and spatiotemporal gait patterns (stride/step width, stride time, double-limb support time, stride length, velocity). RESULTS: Wearing textured insoles led to reductions in CoP velocity measures when standing on foam with eyes open and closed when compared to barefoot (p values ≤0.02). Textured insoles did not appear to be consistently superior to smooth insoles or shoes only for improving gait. Relative to the insole/shoe conditions, walking barefoot led to poorer gait performance for the even and uneven surface tasks (p values ≤0.03). CONCLUSIONS: For pwMS, stimulating the foot with "texture" appears to provide enhanced sensory input with the capacity to improve CoP movement control during standing; offering a potential new treatment option for balance rehabilitation. Further research is needed to identify which individuals may benefit most from textured insoles.Implications for rehabilitationTextured shoe insoles, designed to stimulate plantar mechanoreceptors, are a novel approach to improve standing balance and walking patterns in people with multiple sclerosis (pwMS).Wearing textured insoles for the first time can lead to improvements in centre of pressure movement control when standing on an unstable compliant supporting surface.Textured insoles offer a potential new treatment technique for balance rehabilitation in pwMS who show early signs of diminished foot sensation.

The purpose of this investigation was to explore the effects of dietary weight loss intervention, with and without the addition of exercise on health-related quality of life, depressive symptoms, and anxiety. As part of the EMPOWER study for women, sixty premenopausal women (BMI of 40.4 ± 6.7) were randomized to energy restriction only (ER) or to exercise plus energy restriction (EXER) for 12 months. Health-related quality of life was assessed using the SF-36, depressive symptoms were assessed using the Beck Depression Inventory II (BDI), and anxiety symptoms using the Spielberger state and trait anxiety questionnaire. All measures were completed at baseline, 3, 6 and 12 months. At 12 months, there were significant (p < 0.05) group-by-time interactions favouring the EXER group for five of the eight domains and the mental component summary score. At 12 months, a significant group-by-time interaction favouring the EXER group is reported for both state and trait anxiety (p = .005 and p = .001, respectively). At 12 months, there was a significant group-by-time interaction for depressive symptoms favouring EXER (p < 0.05). Within-group changes for BDI scores were improved at all follow-up time points in the EXER group. Exercise training confers an additional benefit to energy restriction in the absence of additional weight loss at 12 months for health-related quality of life, depressive symptoms, and state and trait anxiety scores when compared to energy restriction only. Exercise and an energy-restricted diet improve health-related quality of life and mental health. Exercise may protect mental health without further weight loss for women with severe obesity.

BACKGROUND: Innovative shoe insoles, designed to enhance sensory information on the plantar surface of the feet, could help to improve walking in people with Multiple Sclerosis. OBJECTIVE: To compare the effects of wearing textured versus smooth insoles, on measures of gait, foot sensation and patient-reported outcomes, in people with Multiple Sclerosis. METHODS: A prospective, randomised controlled trial was conducted with concealed allocation, assessor blinding and intention-to-treat analysis. Thirty ambulant men and women with multiple sclerosis (MS) (Disease Steps rating 1-4) were randomly allocated to wear textured or smooth insoles for 12 weeks. Self-reported insole wear and falls diaries were completed over the intervention period. Laboratory assessments of spatiotemporal gait patterns, foot sensation and proprioception, and patient-reported outcomes, were performed at Weeks 0 (Baseline 1), 4 (Baseline 2) and 16 (Post-Intervention). The primary outcome was the size of the mediolateral base of support (stride/step width) when walking over even and uneven surfaces. Independent t-tests were performed on change from baseline (average of baseline measures) to post-intervention. RESULTS: There were no differences in stride width between groups, when walking over the even or uneven surfaces (P ≥ 0.20) at post-intervention. There were no between-group differences for any secondary outcomes including gait (all P values > 0.23), foot sensory function (all P values ≥ 0.08) and patient-reported outcomes (all P values ≥ 0.23). CONCLUSIONS: In our small trial, prolonged wear of textured insoles did not appear to alter walking or foot sensation in people with MS who have limited foot sensory loss. Further investigation is needed to explore optimal insole design. CLINICAL TRIAL REGISTRATION: Australian and New Zealand Clinical Trials Registry (ACTRN12615000421538).

People living with obesity experience weight stigma in most social settings. This has a negative impact on their health and quality of life. A primary contributor to weight stigma is the misconception that obesity is caused by factors solely within an individual's control. However, this disregards the complex and multifaceted nature of obesity. Weight stigma is perpetuated by the media, healthcare practitioners and researchers, and even in public health campaigns and policies designed to help people living with obesity. This perspective article is a public health call to action to address weight stigma in Australia. We provide key recommendations for public health researchers, practitioners, and policy makers.

Obesity is a complex and multifactorial chronic disease with genetic, environmental, physiological and behavioural determinants that requires long-term care. Obesity is associated with a broad range of complications including type 2 diabetes, cardiovascular disease, dyslipidaemia, metabolic associated fatty liver disease, reproductive hormonal abnormalities, sleep apnoea, depression, osteoarthritis and certain cancers. An algorithm has been developed (with PubMed and Medline searched for all relevant articles from 1 Jan 2000-1 Oct 2021) to (i) assist primary care physicians in treatment decisions for non-pregnant adults with obesity, and (ii) provide a practical clinical tool to guide the implementation of existing guidelines (summarised in Appendix 1) for the treatment of obesity in the Australian primary care setting. MAIN RECOMMENDATIONS AND CHANGES IN MANAGEMENT: Treatment pathways should be determined by a person's anthropometry (body mass index (BMI) and waist circumference (WC)) and the presence and severity of obesity-related complications. A target of 10-15% weight loss is recommended for people with BMI 30-40â¯kg/m2 or abdominal obesity (WC > 88â¯cm in females, WC > 102â¯cm in males) without complications. The treatment focus should be supervised lifestyle interventions that may include a reduced or low energy diet, very low energy diet (VLED) or pharmacotherapy. For people with BMI 30-40â¯kg/m2 or abdominal obesity and complications, or those with BMI >â¯40â¯kg/m2 a weight loss target of 10-15% body weight is recommended, and management should include intensive interventions such as VLED, pharmacotherapy or bariatric surgery, which may be required in combination. A weight loss target of >â¯15% is recommended for those with BMI >â¯40â¯kg/m2 and complications and they should be referred to specialist care. Their treatment should include a VLED with or without pharmacotherapy and bariatric surgery.

Quality of life is a key outcome that is not rigorously measured in obesity treatment research due to the lack of standardization of patient-reported outcomes (PROs) and PRO measures (PROMs). The S.Q.O.T. initiative was founded to Standardize Quality of life measurement in Obesity Treatment. A first face-to-face, international, multidisciplinary consensus meeting was conducted to identify the key PROs and preferred PROMs for obesity treatment research. It comprised of 35 people living with obesity (PLWO) and healthcare providers (HCPs). Formal presentations, nominal group techniques, and modified Delphi exercises were used to develop consensus-based recommendations. The following eight PROs were considered important: self-esteem, physical health/functioning, mental/psychological health, social health, eating, stigma, body image, and excess skin. Self-esteem was considered the most important PRO, particularly for PLWO, while physical health was perceived to be the most important among HCPs. For each PRO, one or more PROMs were selected, except for stigma. This consensus meeting was a first step toward standardizing PROs (what to measure) and PROMs (how to measure) in obesity treatment research. It provides an overview of the key PROs and a first selection of the PROMs that can be used to evaluate these PROs.

Developing work on the nature and consequences of negative intergroup contact, this study explores its potential role in sustaining everyday experiences of dehumanization; that is, experiences in which participants report feeling deprived of full human status. As a case study, we explore domestic service relations in a neighbourhood of Pietermaritzburg, South Africa, analysing interviews (n = 22) conducted with Black domestic workers and their families (n = 64 participants in total) about their day-to-day interactions with Indian employers. Drawing on thematic analysis of accounts of paid domestic labour and food-sharing practices, we argue that negative contact experiences may cumulatively engender a sense of dehumanization and associated feelings of humiliation: a response marked by intertwined constructions of shame and injustice. Implications for understanding wider problems of intergroup conflict and political solidarity are discussed and avenues for future research proposed.

Recent findings in experimental models have shown that the microRNA miR-132 (mir-132) is an important regulator of liver homeostasis and lipid metabolism. We aimed to assess miR-132 expression in liver and fat tissues of obese individuals and examine its association with blood pressure (BP) and hepatic steatosis. We examined obese individuals undergoing bariatric surgery for weight loss (n = 19). Clinical and demographic information was obtained. Quantitative PCR was performed to determine tissue expression of miR-132 in liver and subcutaneous and visceral fat biopsies obtained during bariatric surgery. Liver biopsies were read by a single liver pathologist and graded for steatosis, inflammation and fibrosis. Participants (aged 39 ± 8.1 years) had a body mass index (BMI) of 42 ± 4.5 kg/m2 and presented with 2.2 ± 1.2 metabolic abnormalities. Supine BP was 127 ± 16/74 ± 11 mmHg. Hepatic and visceral fat expression of miR-132 were correlated (r = 0.59, P = 0.033). There was no correlation between subcutaneous and visceral expression of miR-132 (r = -0.31, P = 0.20). Hepatic and visceral fat miR-132 expression were associated with BMI (r = 0.62 and r = 0.68, P = 0.049 respectively) and degree of liver steatosis (r = 0.60 and r = 0.55, P < 0.05, respectively). Subcutaneous fat miRNA-132 expression was correlated to office systolic BP (r = 0.46, P < 0.05), several aspects of 24 h BP (24 h systolic BP: r = 0.52; day systolic BP: r = 0.59, P < 0.05 for all), plasma triglycerides (r = 0.51, P < 0.01) and liver enzymes (ALT: r = -0.52; AST: r = -0.48, P < 0.05 for all). We found an association between miR-132 and markers of cardiovascular and metabolic disease. Reduction of miR-132 may be a target for the regulation of liver lipid homeostasis and control of obesity-related blood pressure.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the role of T- and B-regulatory cells (Tregs and Bregs) in the pathogenesis of idiopathic granulomatous mastitis (IGM). METHODS: This study includes 47 patients with pathologically proven IGM (Group P) and 26 healthy subjects (Group C). The patients in Group P were divided into two groups according to whether their lesions were active (Group PA, n: 21) or in remission (Group PR, n: 26). By using flow-cytometry, the frequencies of CD3+CD4+CD45RA-Foxp3high activated Tregs (aTregs), CD3+CD4+CD45RA-Foxp3low non-suppressive Tregs, CD3+CD4+CD45RA+Foxp3low resting Tregs (rTregs), CD3+CD4+CD25+Foxp3- T-effector cells (Teff), total Tregs and Bregs were analyzed in all subjects. RESULTS: The frequency of the Teff cells was statistically higher in Group P when compared with Group C (p =.004). The Foxp3 expression of Treg cells and the frequency of non-suppressive Tregs in Group P were statistically lower than Group C (p =.032 and p =.02, respectively). In addition, Group PR's Foxp3 expressions were statistically lower than Group C (p =.027); Group PR's aTregs ratio was statistically lower than Group PA (p =.021); and the non-suppressive Tregs ratio of Group PR was lower than both Group PA and Group C (p =.006 and p <.0001). No significant differences were seen Bregs and B cell subsets. CONCLUSION: Significant changes in Foxp3 expression and Treg subsets were seen in patients with active IGM lesion and in remission. This study shows an intrinsic defect of Tregs in patients with IGM.

OBJECTIVES: Symptoms associated with lung cancer and thoracic surgery might increase fall risk. We aimed to investigate: 1) balance, gait and functional status in people post-thoracic surgery compared to healthy controls; 2) perceptions of balance, gait and functional status. METHODS: Recruitment targeted older adults (≥50 years) who had undergone thoracic surgery for a diagnosis of lung cancer in the previous 3 months, and healthy age-matched controls. Dynamic and static balance, gait velocity, knee-extension strength and physical activity levels were assessed using the BESTest, Kistler force plate, GAITRite system, Biodex System 3 and CHAMPS questionnaire, respectively. Two-part semi-structured interviews were conducted post-surgery. RESULTS: Individuals post-surgery (n = 15) had worse dynamic balance and gait, and lower levels of moderate/vigorous physical activity (MVPA) (all p<0.05) versus healthy controls (n = 15). Strength did not differ between groups (p > 0.05). No associations between BESTest and strength or physical activity existed post-surgery (p > 0.05). Three themes were identified: 1) Symptoms affect daily activities; 2) Functional assessments alter perceptions of balance ability and 3) Open to supervised rehabilitation. CONCLUSION: Balance, gait and MVPA are impaired post-thoracic surgery, yet balance was not viewed to be important in enabling activities of daily living. However, supervised rehabilitation was considered acceptable.
