RESUMO

Background: Religiosity is known to have a socio-cultural influence on food choice. However, to date, research exploring the influence of Islam on food selection has almost exclusively focused on fasting during Ramadan and has not explored the influences of Islam on everyday food choices among Muslim people. Aim: This qualitative study explored the influence of Islamic religiosity on everyday food choices among Muslim people. Methods: Thirty-two adult participants residing in the United Kingdom (n = 16 faith leaders and n = 16 lay Muslim people) were recruited from three Sunni mosques, and data was collected using semi-structured interviews. The data was analysed using reflexive thematic analysis and a constant comparison method was applied to draw out similarities and differences between faith leaders and lay Muslim people. Results: The results revealed that Islamic religiosity had an influence over food choice with two main overarching themes 1) Demonstrating religious obedience through food choices and, 2) Spheres of influence on food choice; and five sub-themes 1a) Trusting in familiar food providers, 1b) Verification of halal authenticity, 1c) Seeking purity within food, 2a) The Prophet Muhammed (Peace Be Upon Him) as a role model for food choice and, 2b) Islamic jurisprudence. Conclusion: These findings provide important insights into the influence of Islam on food choice and could be used support the design of faith-informed dietary interventions among Muslim people. Further research is required to examine the role of faith-informed dietary intervention in the Muslim community.

RESUMO

BACKGROUND: Primary care and community healthcare professionals (HCPs) are well placed to discuss child excess weight with parents and support them to make changes. However, HCPs have concerns about addressing this issue. There is a need to understand the factors that influence HCPs in initiating these conversations to inform strategies to support them. AIM: To explore with HCPs, working in primary care and community settings, their experiences of having conversations about child weight with parents, and the factors that create barriers or facilitate them to have these conversations. DESIGN AND SETTING: A qualitative study with GPs, primary care nurses (PNs), and school nurses (SNs) in England. METHOD: GPs and PNs were recruited to participate in semi-structured interviews. SNs from a community healthcare NHS trust were recruited to participate in focus groups. Vignettes were used to stimulate discussion. Data were analysed guided by the Framework approach. RESULTS: Thirteen GPs, seven PNs, and 20 SNs participated. The following three themes were identified regarding barriers to HCPs having conversations about child excess weight: structural and organisational; HCP related; and parent or family related. The themes identified for the factors that facilitate these conversations were: structural changes (for example, dedicated appointments, access to weight assessment data, joined-up working across agencies); HCP approaches (for example, providing appropriate dietary and physical activity advice); and HCP knowledge and skills (for example, enhancing HCPs' general and weight management-related skills and knowledge of child weight management services). CONCLUSION: A range of barriers exist to HCPs addressing child excess weight with parents in primary care and community settings. Actions to effect structural changes and support HCPs in developing relevant knowledge and skills are required to overcome these barriers.

RESUMO

Post bariatric hypoglycaemia (PBH) is typically a post-prandial hypoglycaemia occurring about 2-4 hours after eating in people who have undergone bariatric surgery. PBH develops relatively late after surgery and often after discharge from post-surgical follow-up by bariatric teams, leading to variability in diagnosis and management in non-specialist centres. AIM: to improve and standardise clinical practice in the diagnosis and management of PBH. OBJECTIVES: (1) to undertake an up-to-date review of the current literature; (2) to formulate practical and evidence-based guidance with regards on the diagnosis and treatment of PBH; (3) to recommend future avenues for research in this condition. METHOD: A scoping review was undertaken after an extensive literature search. A consensus on the guidance and confidence in the recommendations was reached by the steering group authors prior to review by key stakeholders. OUTCOME: We make pragmatic recommendations for the practical diagnosis and management of PBH including criteria for diagnosis and recognition, as well as recommendations for research areas that should be explored.

RESUMO

The health benefits of bariatric surgery are well documented; however, the occurrence of weight-regain after surgery, along with the development of mental health difficulties poses a question of how contemporary psychology could assist to prepare people living with obesity prior to undergoing bariatric surgery. This research explored individuals' (in the immediate pre-operative and post-operative population) attitudes, beliefs and experiences towards obesity and their journey to bariatric surgery. Seventeen adult participants (males n = 4; age range: 26-64 years) were recruited and participated in a semi-structured interview. Twelve individuals participated prior to undergoing bariatric surgery. Five individuals participated in the early post-operative period (<3 months post-surgery). People living with obesity displayed high optimism for positive outcomes, with participants hoping that bariatric surgery would be different to previous attempts at weight regulation, with there being a clear shift in the locus of control for weight management from self to healthcare professionals. Whilst this is adaptive, there was the presence of seemingly unrealistic optimism, with many pre-surgery participants not relaying the realistic possibility of post-surgery weight-regain. Despite the optimism individuals feel about bariatric surgery, participants felt that the psychological factors influencing eating behaviours are not being addressed by healthcare. These findings suggest that mindfulness, mindful eating, and self-compassion approaches should be incorporated into clinical practice to support weight regulation and adaption to physiological changes after bariatric surgery.

RESUMO

BACKGROUND: The prevalence of obesity is rising globally and effective strategies to treat obesity are needed. Intermittent fasting, a dietary intervention for weight management, has received growing interest from the general public, as well as healthcare professionals, as a form of lifestyle intervention. METHODS: We executed a rapid review using PUBMED database to identify systematic reviews that examined the impact of intermittent fasting on metabolic indices, published between 2011 and 2022. RESULTS: Intermittent fasting leads to weight loss of a similar magnitude to continuous energy restriction. Most of the evidence shows that intermittent fasting leads to greater fat loss as measured by fat mass (kg) or body fat percentage compared to an ad libitum diet, but fat loss attained during intermittent fasting is not significantly different to continuous energy restriction, although recent evidence shows intermittent fasting to be superior. There is mixed evidence for the impact of intermittent fasting on insulin resistance, fasting glucose and lipid profile. Some studies focused on populations of Muslim people, which showed that Ramadan fasting may lead to weight loss and improvement of metabolic parameters during fasting, although the effects are reversed when fasting is finished. CONCLUSIONS: Intermittent fasting is more effective than an ad libitum dietary intake, and equally or more effective as continuous energy restriction, for weight management. However, there is inconclusive evidence on whether intermittent fasting has a clinically beneficial effect on glucose and lipid metabolism.

RESUMO

High quality biological reagents are a prerequisite for pharmacological research. Herein a protein production screening approach, including quality assessment methods, for protein-based discovery research is presented. Trends from 2895 expression constructs representing 253 proteins screened in mammalian and bacterial hosts-91% of which are successfully expressed and purified-are discussed. Mammalian expression combined with the use of solubility-promoting fusion proteins is deemed suitable for most targets. Furthermore, cases utilizing stable cell line generation and choice of fusion protein for higher yield and quality of difficult-to-produce proteins (Leucine-rich repeat-containing G-protein coupled receptor 4 (LGR4) and Neurturin) are presented and discussed. In the case of Neurturin, choice of fusion protein impacted the target binding 80-fold. These results highlight the need for exploration of construct designs and careful Quality Control (QC) of difficult-to-produce protein reagents.

RESUMO

Background: Idiopathic intracranial hypertension (IIH) is a neurometabolic condition severely impacting the quality of life of people living with IIH (PwIIH). Most PwIIH are overweight or live with obesity, and weight loss is recommended by healthcare professionals (HCPs) as it is central to disease management. There is currently no research evaluating patient-clinician interactions when discussing weight management in IIH. The aim of this study was to evaluate the patient experience of communication with HCPs regarding weight management from the perspective of PwIIH. Methods: A cross-sectional online survey was developed and distributed by the IIH UK charity via their mailing list and social media network. Eligible participants were adults with IIH who have been recommended to lose weight by their HCP. Descriptive statistics were used to summarise quantitative responses and content analysis was used to inductively draw out themes from open-ended free-text responses. Results: There were 625 respondents. One-fifth of PwIIH (n=127/603, 21%) felt that HCPs were supportive and empathetic about weight management. Five themes were identified on how experiences regarding weight management for IIH can be improved, with PwIIH recommending for HCPs to: (1) detail the relationship between IIH and weight, (2) individualise care, (3) give advice, (4) provide support and (5) adapt communication. Conclusion: The majority of PwIIH recalled a poor experience and negative emotions when engaged in discussions regarding weight management with their HCPs. Further research should explore the HCPs perspective and evaluate interventions aiming to improve the quality of patient-HCPs communication in IIH.

RESUMO

BACKGROUND AND OBJECTIVES: Idiopathic intracranial hypertension (IIH) is associated with obesity; however, there is a lack of clinical consensus on how to manage weight in IIH. The aim of this systematic review was to evaluate weight loss interventions in people with IIH to determine which intervention is superior in terms of weight loss, reduction in intracranial pressure (ICP), benefit to visual and headache outcomes, quality of life, and mental health. METHODS: A systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and registered with PROSPERO (CRD42023339569). MEDLINE and CINAHL were searched for relevant literature published from inception until December 15, 2022. Screening and quality appraisal was conducted by 2 independent reviewers. Recommendations were graded using Scottish Intercollegiate Guidelines Network methodology. RESULTS: A total of 17 studies were included. Bariatric surgery resulted in 27.2-27.8 kg weight loss at 24 months (Level 1- to 1++). Lifestyle weight management interventions resulted in between 1.4 and 15.7 kg weight loss (Level 2+ to 1++). Bariatric surgery resulted in the greatest mean reduction in ICP (-11.9 cm H2O) at 24 months (Level 1++), followed by multicomponent lifestyle intervention + acetazolamide (-11.2 cm H2O) at 6 months (Level 1+) and then a very low-energy diet intervention (-8.0 cm H2O) at 3 months (Level 2++). The least ICP reduction was shown at 24 months after completing a 12-month multicomponent lifestyle intervention (-3.5 cm H2O) (Level 1++). Reduction in body weight was shown to be highly correlated with reduction in ICP (Level 2++ to 1++). DISCUSSION: Bariatric surgery should be considered for women with IIH and a body mass index (BMI) ≥35 kg/m2 since this had the most robust evidence for sustained weight management (grade A). A multicomponent lifestyle intervention (diet + physical activity + behavior) had the most robust evidence for modest weight loss with a BMI <35 kg/m2 (grade B). Longer-term outcomes for weight management interventions in people with IIH are required to determine whether there is a superior weight loss intervention for IIH.

RESUMO

BACKGROUND: Endoscopic sleeve gastroplasty (ESG) is a minimally invasive procedure that has been demonstrated in the MERIT randomised, controlled trial to result in substantial and durable additional weight loss in adults with obesity compared with lifestyle modification (LM) alone. We sought to conduct the first cost-effectiveness analysis of ESG versus LM alone in adults with class II obesity (BMI 35.0-39.9 kg/m2) from a national healthcare system perspective in England based on results from this study. METHODS: A 6-state Markov model was developed comprising 5 BMI-based health states and an absorbing death state. Baseline characteristics, utilities, and transition probabilities were informed by patient-level data from the subset of patients with class II obesity in MERIT. Adverse events (AEs) were based on the MERIT safety population. Mortality was estimated by applying BMI-specific hazard ratios from the published literature to UK general population mortality rates. Utilities for the healthy weight and overweight health states were informed from the literature; disutility associated with increasing BMI in the class I-III obesity health states was estimated using MERIT utility data. Disutility due to AEs and the prevalence of obesity-related comorbidities were based on the literature. Costs included intervention costs, AE costs, and comorbidity costs. RESULTS: ESG resulted in higher overall costs than LM alone but led to an increase in quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) for ESG vs LM alone was £2453/QALY gained. ESG was consistently cost effective across a wide range of sensitivity analyses, with no ICER estimate exceeding £10,000/QALY gained. In probabilistic sensitivity analysis, the mean ICER was £2502/QALY gained and ESG remained cost effective in 98.25% of iterations at a willingness-to-pay threshold of £20,000/QALY. CONCLUSION: Our study indicates that ESG is highly cost effective versus LM alone for the treatment of adults with class II obesity in England.

RESUMO

Microproteins (MPs) are a potentially rich source of uncharacterized metabolic regulators. Here, we use ribosome profiling (Ribo-seq) to curate 3,877 unannotated MP-encoding small ORFs (smORFs) in primary brown, white, and beige mouse adipocytes. Of these, we validated 85 MPs by proteomics, including 33 circulating MPs in mouse plasma. Analyses of MP-encoding mRNAs under different physiological conditions (high-fat diet) revealed that numerous MPs are regulated in adipose tissue in vivo and are co-expressed with established metabolic genes. Furthermore, Ribo-seq provided evidence for the translation of Gm8773, which encodes a secreted MP that is homologous to human and chicken FAM237B. Gm8773 is highly expressed in the arcuate nucleus of the hypothalamus, and intracerebroventricular administration of recombinant mFAM237B showed orexigenic activity in obese mice. Together, these data highlight the value of this adipocyte MP database in identifying MPs with roles in fundamental metabolic and physiological processes such as feeding.

RESUMO

BACKGROUND: Liver-reducing diets (LRDs) are mandated prior to bariatric surgery, but there are no guidelines on their implementation. OBJECTIVE: To establish the variation and effectiveness of LRDs utilized in clinical practice. SETTING: A nationwide, multicenter, retrospective cohort study. METHODS: A total of 1699 adult patients across 14 bariatric centers in the United Kingdom were included. Multilevel logistic regression models were developed to examine factors predictive of 5% weight loss. RESULTS: Most centers (n = 9) prescribed an 800- to 1000-kcal diet, but the duration and formulation of diet was variable. Overall, 30.6% (n = 510) of patients achieved 5% weight loss during the LRD. After adjustment for preoperative weight, women had reduced odds (odds ratio [OR], .65; 95% confidence interval [CI], .48-.88; P = .005), while increasing age (OR, 1.01; 95% CI, 1.00-1.02; P = .043) and having type 2 diabetes (OR, 1.49; 95% CI, 1.16-1.92; P = .002) increased odds of 5% weight loss. A normal consistency food LRD (OR, .64; 95% CI, .42-.98; P = .041) and energy prescription of >1200 kcals/d (OR, .33; 95% CI, .13-.83; P = .019) reduced odds, while an LRD with a duration of 3 weeks (OR, 2.28; 95% CI, 1.02-5.09; P = .044) or greater increased odds of 5% weight loss. CONCLUSIONS: There is wide variation in how LRDs are delivered in clinical practice, highlighting the need for an evidence-based consensus. Our findings suggest the optimal LRD before bariatric surgery contains 800 to 1200 kcals/d over a duration of 3 to 4 weeks. Further research is required to determine the optimal formulation of LRD and whether women may require a lower-energy LRD than men.

RESUMO

Changing composition of the gut microbiome is an important component of the gut adaptation to various environments, which have been implicated in various metabolic diseases including obesity and type 2 diabetes, but the mechanisms by which the microbiota influence host physiology remain contentious. Here we find that both diets high in the fermentable fiber inulin and vertical sleeve gastrectomy increase intestinal expression and circulating levels of the anti-microbial peptide Reg3g. Moreover, a number of beneficial effects of these manipulations on gut function, energy balance, and glucose regulation are absent in Reg3g knockout mice. Peripheral administration of various preparations of Reg3g improves glucose tolerance, and this effect is dependent on the putative receptor Extl3 in the pancreas. These data suggest Reg3g acts both within the lumen and as a gut hormone to link the intestinal microbiome to various aspects of host physiology that may be leveraged for novel treatment strategies.

RESUMO

Idiopathic intracranial hypertension (IIH) is more common in women of reproductive age who have obesity, yet there is little information on its management specifically in pregnancy. Women with IIH should plan their pregnancy including discussing contraception before pregnancy, recognising that hormonal contraceptives are not contraindicated. Potentially teratogenic medications including acetazolamide and topiramate are not recommended during pregnancy or in those with immediate plans to conceive; prescribing acetazolamide in pregnancy must only follow discussion with the patient and their obstetrician. Ideally, patients should aim to achieve disease remission or control before pregnancy, through optimising their weight. Although weight gain is expected in pregnancy, excessive weight gain may exacerbate IIH and increase maternal and fetal complications; evidence-based recommendations for non-IIH pregnancies may help in guiding optimal gestational weight gain. The vast majority of women with IIH can have a normal vaginal delivery, with spinal or epidural anaesthesia if needed, provided the papilloedema is stable or the IIH is in remission.

RESUMO

BACKGROUND: Bariatric and Metabolic Surgery (BMS) is a popular weight loss intervention worldwide, yet few scientific studies have examined variations in preoperative practices globally. This study aimed to capture global variations in preoperative practices concerning patients planned for BMS. METHODS: A 41-item questionnaire-based survey was designed and the survey link was freely distributed on social and scientific media platforms, email groups and circulated through personal connections of authors. The survey included eight parts: basic information; criteria for BMS; preoperative nutritional screening; preoperative weight loss; preoperative diets for liver size reduction; preoperative glycemic control; other laboratory investigations and preparations; decision making, education, and consents. Descriptive statistics were used to analyse data and graphs were used for representation where applicable. RESULTS: Six hundred thirty-four bariatric healthcare professionals from 76 countries/regions completed the survey. Of these, n = 310 (48.9%) were from public hospitals, n = 466 (73.5%) were surgeons, and the rest were multidisciplinary professionals. More than half of respondents reported using local society/association guidelines in their practice (n = 310, 61.6%). The great majority of respondents routinely recommend nutritional screening preoperatively (n = 385, 77.5%), mandatory preoperative diets for liver size reduction (n = 220, 53.1%), routine screening for T2DM (n = 371, 90.7%), and mandate a glycemic control target before BMS in patients with T2DM (n = 203, 55.6%). However, less than half (n = 183, 43.9%) recommend mandatory preoperative weight loss to all patients. Most respondents (n = 296, 77.1%) recommend psychological intervention before surgery for patients diagnosed with psychological conditions. Variations were also identified in laboratory investigations and optimisation; and in the aspects of decision making, education and consent. CONCLUSIONS: This survey identified significant global variations in preoperative practices concerning patients seeking primary BMS. Our findings could facilitate future research for the determination of best practice in these areas of variations, and consensus-building to guide clinical practice while we wait for that evidence to emerge.

RESUMO

BACKGROUND: Bariatric surgery is the most effective treatment for severe obesity. However, without recommended follow-up it has long-term risks. AIM: To investigate whether nutritional and weight monitoring in primary care meets current clinical guidance, after patients are discharged from specialist bariatric care. DESIGN AND SETTING: Retrospective cohort study in primary care practices contributing to IQVIA Medical Research Data in the UK (1 January 2000 to 17 January 2018). METHOD: Participants were adults who had had bariatric surgery with a minimum of 3 years' follow-up post-surgery, as this study focused on patients discharged from specialist care (at 2 years post-surgery). Outcomes were the annual proportion of patients from 2 years post-surgery with a record of recommended nutritional screening blood tests, weight measurement, and prescription of nutritional supplements, and the proportions with nutritional deficiencies based on blood tests. RESULTS: A total of 3137 participants were included in the study, and median follow-up post-surgery was 5.7 (4.2-7.6) years. Between 45% and 59% of these patients had an annual weight measurement. The greatest proportions of patients with a record of annual nutritional blood tests were for tests routinely conducted in primary care, for example, recorded haemoglobin measurement varied between 44.9% (n = 629/1400) and 61.2% (n = 653/1067). Annual proportions of blood tests specific to bariatric surgery were low, for example, recorded copper measurement varied between 1.2% (n = 10/818) and 1.5% (n = 16/1067) where recommended. Results indicated that the most common deficiency was anaemia. Annual proportions of patients with prescriptions for recommended nutritional supplements were low. CONCLUSION: This study suggests that patients who have bariatric surgery are not receiving the recommended nutritional monitoring after discharge from specialist care. GPs and patients should be supported to engage with follow-up care. Future research should aim to understand the reasons underpinning these findings.

RESUMO

BACKGROUND: The COVID-19 pandemic has had a significant adverse impact on the delivery of weight management programmes (WMPs), in order to ensure the safety of patients and healthcare professionals. Videoconferencing could provide safe remote access to group WMPs during the COVID-19 pandemic. The objectives of this study were to determine the uptake of a virtual group WMP and its predictors. METHODS: All patients enrolled on a face-to-face group WMP, which constitutes part of a Tier 3 WMP delivered by the NHS, at the time of the COVID-19 pandemic lockdown were invited to transfer to a virtual format of the group WMP. Baseline data included weight, BMI, age, gender, ethnicity and Index of Multiple Deprivation (IMD) quintile score. The outcomes were accept/decline transfer to the virtual group WMP. Logistic regression was performed to assess for predictors of uptake. RESULTS: The 315 participants were included, of which 72.1% (n = 227) accepted. After adjusting for gender, deprivation and BMI; older patients (OR 0.966, [95% CI 0.944, 0.989]; p = 0.003) and Black, Asian and Minority Ethnicity (BAME) patients (OR 0.460 [95% 0.248, 0.851]; p = 0.023) were less likely to accept the virtual group WMP. CONCLUSION: Strategies aimed at improving uptake of group WMP among BAME and older adult groups are needed, particularly considering the increased risk of severe COVID-19 in these two groups, and the links between obesity and poor COVID-19 outcomes.

RESUMO

PURPOSE OF THE REVIEW: Pathways for obesity prevention and treatment are well documented, yet the prevalence of obesity is rising, and access to treatment (including bariatric surgery) is limited. This review seeks to assess the current integrated clinical pathway for obesity management in England and determine the major challenges. RECENT FINDINGS: Evidence for tier 2 (community-based lifestyle intervention) and tier 3 (specialist weight management services) is limited, and how it facilitates care and improve outcomes in tier 4 remains uncertain. Treatment access, rigidity in pathways, uncertain treatment outcomes and weight stigma seems to be major barriers to improved care. More emphasis must be placed on access to effective treatments, treatment flexibility, addressing stigma and ensuring treatment efficacy including long-term health outcomes. Prevention and treatment should both receive significant focus though should be considered to be largely separate pathways. A simplified system for weight management is needed to allow flexibility and the delivery of personalized care including post-bariatric surgery care for those who need it.

RESUMO

BACKGROUND: Many bariatric surgical centers mandate achieving weight loss targets through medical weight management (MWM) programs before offering bariatric surgery, but the evidence for this is unclear. OBJECTIVES: To examine the relationship between weight changes during (1) MWM, and (2) preoperative low-energy-diet (LED), and weight changes at 12 and 24 months after surgery. SETTING: Multicenter community- and acute-based MWM services referring to one regional bariatric center, United Kingdom. METHODS: A retrospective cohort study of patients who attended MWM and then underwent a primary laparoscopic bariatric procedure (adjustable gastric banding [LAGB], or Roux-en-Y gastric bypass [RYGB]) in a single bariatric center in the United Kingdom between 2013 and 2015. Data were collected from patient electronic records. RESULTS: Two hundred eight patients were included (LAGB n = 128, RYGB n = 80). Anthropometric data were available for 94.7% and 88.0% of participants at 12 and 24 months, respectively. There was no relationship between weight loss during MWM and after surgery at either 12 or 24 months. Weight loss during the preoperative LED predicted greater weight loss after LAGB (ß = .251, P = .006) and less weight loss after RYGB (ß = -.390, P = .003) at 24 months, after adjusting for age, sex, ethnicity, baseline weight, and LED duration. CONCLUSIONS: Weight loss in MWM does not predict greater weight loss outcomes up to 24 months after LAGB or RYGB. Greater weight loss during the preoperative LED predicted greater weight loss after LAGB and less weight loss after RYGB. Our results suggest that patients should not be denied bariatric surgery because of not achieving weight loss in MWM. Weight loss responses to preoperative LEDs as a predictor of postsurgical weight loss requires further investigation.

RESUMO

New drugs that target Plasmodium species, the causative agents of malaria, are needed. The enzyme N-myristoyltransferase (NMT) is an essential protein, which catalyzes the myristoylation of protein substrates, often to mediate membrane targeting. We screened ∼1.8 million small molecules for activity against Plasmodium vivax (P. vivax) NMT. Hits were triaged based on potency and physicochemical properties and further tested against P. vivax and Plasmodium falciparum (P. falciparum) NMTs. We assessed the activity of hits against human NMT1 and NMT2 and discarded compounds with low selectivity indices. We identified 23 chemical classes specific for the inhibition of Plasmodium NMTs over human NMTs, including multiple novel scaffolds. Cocrystallization of P. vivax NMT with one compound revealed peptide binding pocket binding. Other compounds show a range of potential modes of action. Our data provide insight into the activity of a collection of selective inhibitors of Plasmodium NMT and serve as a starting point for subsequent medicinal chemistry efforts.
