Probiotic-Induced Modulation of Microbiota Composition and Antibiotic Resistance Genes Load, an In Vitro Assessment.

The imbalance of the gut microbiota (GM) is known as dysbiosis and is associated with disorders such as obesity. The increasing prevalence of microorganisms harboring antibiotic resistance genes (ARG) in the GM has been reported as a potential risk for spreading multi-drug-resistant pathogens. The objective of this work was the evaluation, in a fecal culture model, of different probiotics for their ability to modulate GM composition and ARG levels on two population groups, extremely obese (OB) and normal-weight (NW) subjects. Clear differences in the basal microbiota composition were observed between NW and OB donors. The microbial profile assessed by metataxonomics revealed the broader impact of probiotics on the OB microbiota composition. Also, supplementation with probiotics promoted significant reductions in the absolute levels of tetM and tetO genes. Regarding the blaTEM gene, a minor but significant decrease in both donor groups was detected after probiotic addition. A negative association between the abundance of Bifidobacteriaceae and the tetM gene was observed. Our results show the ability of some of the tested strains to modulate GM. Moreover, the results suggest the potential application of probiotics for reducing the levels of ARG, which constitutes an interesting target for the future development of probiotics.

Whole-Exome Sequencing identified Olfactory Receptor genes as a key contributor to extreme obesity with progression to nonalcoholic steatohepatitis in Mexican patients: Olfactory receptor genes in obese NASH patients.

INTRODUCTION AND OBJECTIVES: Obesity is a global health problem that triggers fat liver accumulation. The prevalence of obesity and the risk of non-alcoholic steatohepatitis (NASH) among young obese Mexican is high. Furthermore, genetic predisposition is a key factor in weight gain and disrupts metabolism. Herein, we used Whole-Exome Sequencing to identify potential causal variants and the biological processes that lead to obesity with progression to NASH among Mexican patients. MATERIALS AND METHODS: Whole-Exome Sequencing was performed in nine obese patients with NASH diagnosis with a BMI ≥30 kg/m2 and one control (BMI=24.2 kg/m2) by using the Ion S5TM platform. Genetic variants were determined by Ion Reporter software. Enriched GO biological set genes were identified by the WebGestalt tool. Genetic variants within ≥2 obese NASH patients and having scores of SIFT 0.0-0.05 and Polyphen 0.85-1.0 were categorized as pathogenic. RESULTS: A total of 1359 variants with a probable pathogenic effect were determined in obese patients with NASH diagnosis. After several filtering steps, the most frequent pathogenic variants found were rs25640-HSD17B4, rs8105737-OR1I1, rs998544-OR5R1, and rs4916685, rs10037067, and rs2366926 in ADGRV1. Notably, the primary biological processes affected by these pathogenic variants were the sensory perception and detection of chemical stimulus pathways in which the olfactory receptor gene family was the most enriched. CONCLUSIONS: Variants in the olfactory receptor genes were highly enriched in Mexican obese patients that progress to NASH and could be potential targets of association studies.

Transvaginal natural orifice endoscopic surgery for extremely obese patients with early-stage endometrial cancer.

AIM: The purpose of this study was to assess the feasibility and efficacy of transvaginal natural orifice transluminal endoscopic surgery (v-NOTES) staging surgery for extreme obese patients with early-stage type-1 endometrial cancer. METHODS: Study included cases of extreme obese patients with early-stage endometrial cancer who underwent v-NOTES between January 2019 and June 2019 at a tertiary referral medical center. The following parameters were noted: patient age, body mass index (BMI), operating time, conversion to conventional laparoscopy or laparotomy, any intraoperative or postoperative complications, estimated blood loss, pre- and postoperative hemoglobin levels, postoperative pain scores of the patients using visual analogue scale (VAS) at 6th, 12th and 24th h, length of hospital stay and final pathology report. RESULTS: Six cases of extreme obese patients with early-stage endometrial cancer underwent hysterectomy and bilateral salpingo-oophorectomy via the transvaginal NOTES. These six patients had a mean body mass index of 51.4 kg/m2 (SD = 6,13). No conversion to conventional laparoscopy or even laparotomy was needed in any of these patients. No adjuvant therapy was needed since all of the patients had early-stage endometrial carcinoma. CONCLUSION: Given the increased risk of surgical morbidity and mortality associated with increasing BMI, it is paramount importance to establish safe surgical approaches to gynecological pathologies. We think that v-NOTES offers greater benefit to obese patients when performed by an experienced surgeon and v-NOTES is a safe, effective and feasible minimally invasive surgery in extreme obese patients with early endometrial cancer.

Health related quality of life associated with extreme obesity in adolescents - results from the baseline evaluation of the YES-study.

BACKGROUND: Obesity can significantly reduce health-related quality of life (HRQoL) and may lead to numerous health problems even in youths. This study aimed to investigate whether HRQoL varies among youths with obesity depending on grade of obesity and other factors. METHODS: For the Youths with Extreme obesity Study (YES) (2012-2014), a prospective multicenter cohort study, a baseline sample of 431 obese and extremely obese adolescents and young adults (age 14 to 24 years, BMI ≥30 kg/m2) was recruited at four German university medical centers and one job center. Obesity grade groups (OGG) were defined according to BMI (OGG I: 30-34.9 kg/m2, OGG II: 35-39.9 kg/m2, OGG III (extreme obesity): ≥40 kg/m2). HRQoL was measured with the Euroqol-5D-3 L (EQ-5D-3 L), DISABKIDS chronic generic (DCGM-31) and the KINDLR obesity module. Differences between OGGs were assessed with logistic and linear regression models, adjusting for age, sex, and study center in the base model. In a second regression analysis, we included other characteristics to identify possible determinants of HRQoL. RESULTS: Three hundred fifty-two adolescents (mean age: 16.6 (±2.4), mean BMI: 39.1 (±7.5) kg/ m2) with available HRQoL data were analysed. HRQoL of youths in all OGGs was markedly lower than reference values of non-obese adolescents. Adjusting for age and sex, HRQoL of youths in OGG III significantly impaired compared to OGG I. Youths in OGG III were 2.15 times more likely to report problems with mobility in the EQ-5D-3 L than youths in OGG I. A mean difference of 9.7 and 6.6 points between OGG III and I were found for DCGM-31 and KINDL respectively and 5.1 points between OGG II and I for DCGM-31. Including further variables into the regression models, showed that HRQoL measured by DCGM-31 was significantly different between OGGs. Otherwise, female sex and having more than 4 h of daily screen time were also associated with lower HRQoL measured by DCGM-31 and KINDL. CONCLUSION: HRQoL of adolescents with obesity is reduced, but HRQoL of adolescents with extreme obesity is particularly affected. Larger and longitudinal studies are necessary to understand the relation of extreme obesity and HRQoL, and the impact of other lifestyle or socioeconomic factors. TRIAL REGISTRATION: Clinicaltrials.gov NCT01625325; German Clinical Trials Register (DRKS) DRKS00004172.

A retrospective case control study identifies peripheral blood mononuclear cell albumin RNA expression as a biomarker for non-alcoholic fatty liver disease.

PURPOSE: Non-alcoholic fatty liver disease (NAFLD) improves after bariatric surgery. The aim of this study was to determine whether peripheral blood mononuclear cell albumin gene expression was related to NAFLD and whether albumin (ALB) and alpha fetoprotein (AFP) expression could be detected in whole blood and visceral adipose tissue. METHODS: Using a retrospective case control study design, RNA isolated from peripheral blood mononuclear cells from patients prior to undergoing bariatric surgery was used for pooled microarray analysis. Quantitative polymerase chain reaction (QPCR) was used to analyze whole blood and visceral adipose tissue. Liver histology was obtained via intra-operative biopsy and clinical data extracted from the electronic health record. RESULTS: The albumin (ALB) gene was the second most up-regulated found in microarray analysis of peripheral blood mononuclear cell RNA from patients with hepatic lobular inflammation versus normal liver histology. Transcript levels of ALB were significantly different across those with normal (n = 50), steatosis (n = 50), lobular inflammation (n = 50), and peri-sinusoidal fibrosis (n = 50) liver histologies, with lobular inflammation 3.9 times higher than those with normal histology (p < 0.017). Albumin expression levels decreased in 11/13 patients in paired samples obtained prior to and at 1 year after Roux-en-Y gastric bypass surgery. ALB expression could be detected in 23 visceral adipose tissue samples obtained intra-operatively and in 18/19 available paired whole blood samples. No significant correlation was found between ALB expression in visceral adipose tissue and whole blood RNA samples. Alpha fetoprotein expression as a marker of early hepatocytic differentiation was detected in 17/17 available VAT RNA samples, but in only 2/17 whole blood RNA samples. CONCLUSION: Albumin RNA expression from blood cells may serve as a biomarker of NAFLD. Albumin and alpha fetoprotein appear to be ubiquitously expressed in visceral adipose tissue in patients with extreme obesity.

Testing a model of body image in the bariatric surgery patient.

PURPOSE: The purpose was to test a published model of body image in the bariatric surgery patient in the clinical office setting. BACKGROUND: A model was created based on clinical observations during field work and the literature. It focuses on five concepts of body image: body attitude, body checking, appearance orientation, perceived body size, and perceived body space. Testing this model 3 months after surgery is important because morphology changes rapidly influencing early changes in body image, yet there is a paucity of research at this time point. METHODS: For this study of 67 bariatric surgery patients, sequential sampling was used. Body image and anthropometric measures (body mass index and other weight loss indicators) were obtained at baseline and 3-months postoperatively. Established model testing criteria were used. RESULTS: Over 3 months, mean body mass index was significantly reduced. Mean body image was significantly improved regarding all concepts in the model, except body checking. Body image improvement varied widely when individual responses were examined. CONCLUSIONS: The model was successfully tested. Data on the five concepts in the model provided a body image profile at 3 months indicating individuals' degree of improvement. Areas of non-improvement in the early postoperative phase may signal the need for interventions, like support or psychological counseling, for patients who might be struggling with views of themselves after surgery. Preliminary recommendations are made regarding several of the instruments and their use clinically. Researchers should take into consideration the study's short 3-month time frame when designing future studies.

Evaluation of electrocardiographic ventricular repolarization parameters in extreme obesity.

BACKGROUND AND OBJECTIVES: The risk of sudden death and cardiac arrhythmia increases in morbidly obese patients. We aimed to evaluate the marker of arrhythmias such as Tp-e/QT, Tp-e/QTc, Tp-e/JT and Tp-e/JTc ratios in extreme obesity. METHODS: The study included 41 extremely obese patients and 41 control subjects. QTmax, QTmin, QRS, JT and Tp-e intervals were measured od 12­lead electrocardiographies. In addition, Tp-e/QT, Tp-e/QTc, Tp-e/JT and Tp-e/JTc rates and QTc, cQTd and JTc intervals were calculated. RESULTS: Tp-e interval (79.2 ±â€¯9.7 ms (milisecond) vs. 68.6 ±â€¯8.1, p < 0.001), QTc interval (395.9 ±â€¯18.8 vs. 377.9 ±â€¯19.3 ms, p < 0.001), JTc interval (317.1 ±â€¯27.0 vs. 297.4 ±â€¯23.2 ms, p = 0.001), Tp-e/QT ratio (0.22 ±â€¯0.03vs. 0.19 ±â€¯0.02, p < 0.001), Tp-e/QTc ratio (0.20 ±â€¯0.26vs. 0.18 ±â€¯0.02, p = 0.001), Tp-e/JT ratio (0.29 ±â€¯0.04 vs. 0.25 ±â€¯0.03, p < 0.001), TPe/JTc ratio (0.25 ±â€¯0.04 vs. 0.23 ±â€¯0.03, p = 0.018), QTd (32.8 ±â€¯10 vs.15 ±â€¯6.4 ms, p < 0.001) and cQTd (70.0 ±â€¯30.1 vs. 31.3 ±â€¯22.4 ms, p < 0.001) were significantly higher in obese patients. CONCLUSION: Compared to healthy subjects potential ECG repolarization predictors were significantly increased in extremely obese patients.

Effect of participation in a park-based afterschool program on cardiovascular disease risk among severely obese youth.

OBJECTIVES: The prevalence of severe obesity in youth is rising, despite reports of obesity rates stabilizing overall. While reports on treatment outcomes for youth with severe obesity (bariatric surgery, behavioral and pharmacological treatments) exist, very few community-based programs have reported changes in health outcomes in this population. We assessed changes in cardiovascular health risk profiles among racial/ethnic minority youth with severe obesity who participated in Fit2Play™, a park-based afterschool health promotion program. STUDY DESIGN: A longitudinal cohort study. METHODS: Children aged 6-14 years (N = 1546, 51% Hispanic, 44% non-Hispanic black) who participated in the Fit2Play™ in one of 34 urban park sites for one school year over five separate school years (2010-2015) had height, weight, four-site skinfold thicknesses, systolic blood pressure (SBP)/diastolic blood pressure (DBP), fitness tests, and a health/wellness knowledge test collected at the beginning and end of the school year. Two-level repeated measures mixed models examined changes in cardiovascular health outcomes (body mass index [BMI], skinfold thickness, systolic/diastolic blood pressure percentile [SBPP/DBPP], cardiorespiratory fitness [PACER]) in youth with severe obesity over 1- and 2-year follow-up. RESULTS: Compared with baseline, BMI decreased 13% (incidence rate ratio [IRR] 95% confidence interval [CI]: 0.83-0.90), sumof skinfold thicknesses decreased 5% (IRR 95% CI: 0.91-0.99), SBPP decreased 5% (IRR 95% CI: 0.90-0.99), DBPP decreased 19% (IRR 95% CI: 0.77-0.86), and PACER scores increased 12% (IRR 95% CI: 1.0-1.27) after two years of participation in the Fit2Play™ program. CONCLUSIONS: Findings here support community/park-based youth programs as effective and accessible treatment options for reducing cardiovascular disease risk among youth with severe obesity.

Extreme obesity is associated with variation in genes related to the circadian rhythm of food intake and hypothalamic signaling.

The hypothalamus is important for regulation of energy intake. Mutations in genes involved in the function of the hypothalamus can lead to early-onset severe obesity. To look further into this, we have followed a strategy that allowed us to identify rare and common gene variants as candidates for the background of extreme obesity from a relatively small cohort. For that we focused on subjects with a well-selected phenotype and on a defined gene set and used a rich source of genetic data with stringent cut-off values. A list of 166 genes functionally related to the hypothalamus was generated. In those genes complete exome sequence data from 30 extreme obese subjects (60 genomes) were screened for novel rare indel, nonsense, and missense variants with a predicted negative impact on protein function. In addition, (moderately) common variants in those genes were analyzed for allelic association using the general population as reference (false discovery rate<0.05). Six novel rare deleterious missense variants were found in the genes for BAIAP3, NBEA, PRRC2A, RYR1, SIM1, and TRH, and a novel indel variant in LEPR. Common variants in the six genes for MBOAT4, NPC1, NPW, NUCB2, PER1, and PRRC2A showed significant allelic association with extreme obesity. Our findings underscore the complexity of the genetic background of extreme obesity involving rare and common variants of genes from defined metabolic and physiologic processes, in particular regulation of the circadian rhythm of food intake and hypothalamic signaling.

Appropriate enoxaparin dose for venous thromboembolism prophylaxis in patients with extreme obesity.

OBJECTIVE: To evaluate the appropriate dose of enoxaparin for venous thromboembolism (VTE) prophylaxis in patients with extreme obesity. METHODS: A literature search was performed using MEDLINE (1950-April 2013) to analyze all English-language articles that evaluated incidence of VTE and/or anti-Xa levels with enoxaparin for thromboprophylaxis in patients with extreme obesity. RESULTS: Eight studies were included in the analysis. Six of the studies were done in patients undergoing bariatric surgery. Mean body mass index ranged from 44.9 to 63.4 kg/m(2) within studies. Studies done with bariatric surgery patients utilized doses of enoxaparin that ranged from the standard dose of 30 mg subcutaneous (SQ) every 12 hours to 60 mg SQ every 12 hours. Other studies evaluated doses ranging from 40 mg SQ every 24 hours to 0.5 mg/kg/day. Only 3 studies evaluated the incidence of VTE as the primary endpoint; the other studies evaluated anti-Xa levels. The studies showed that appropriate anti-Xa levels were achieved more often with higher than standard doses of enoxaparin. One study showed that enoxaparin 40 mg SQ every 12 hours decreased the incidence of VTE in patients undergoing bariatric surgery compared to standard doses. Overall risk of bleeding was similar between study groups. CONCLUSIONS: Higher than standard doses of enoxaparin may be needed for patients with extreme obesity. Patients undergoing bariatric surgery may benefit from enoxaparin 40 mg SQ every 12 hours. Additional large randomized, controlled trials are needed to determine the efficacy and safety of higher than standard doses of enoxaparin for VTE prophylaxis in patients with extreme obesity.

Laparoscopic Sleeve Gastrectomy Smart Trocar Site Modification in Patients with Extreme Obesity.

PURPOSE: Laparoscopic sleeve gastrectomy (LSG) is one of the most common bariatric surgeries performed worldwide. Although it has established itself as a satisfactory procedure on its own, it can also function as the first part of a two-stage treatment strategy. This is especially true in situations of extreme obesity (obesity grade IV or higher). One rationale for choosing a two-stage treatment is the technical difficulty of doing other types of bariatric procedures involving anastomoses due to body physique and level of visceral adiposity. LSG in patients with such a high body mass index (BMI) is comparatively simpler technically, but it does also have a degree of complexity for similar reasons. Here, we present an innovative port configuration for LSG that can significantly reduce ergonomic challenges and enhance the safety of the procedure in patients with extreme obesity. MATERIALS AND METHODS: This new trocar site arrangement is generally suitable for individuals with grade IV obesity or above. It is especially effective for people with obesity at or above grade V. Only standard laparoscopic instruments are used. RESULTS: This design preserves the ideal manipulation and elevation angles at 60° and allows surgeons to use standard laparoscopic instruments with lowered shoulders, reducing muscular strain and fatigue. Additionally, it improves patient safety. CONCLUSION: In patients with extreme obesity, this proposed port configuration for LSG can significantly reduce ergonomic difficulties and increase surgical safety.

Maternal and perinatal outcomes of extreme obesity in pregnancy.

OBJECTIVE: To evaluate the effects of extreme obesity (pre-pregnancy BMI ≥ 50.0 kg/m2) in pregnancy on maternal and perinatal outcomes. METHODS: We conducted a population-based cohort study using the Newfoundland and Labrador Perinatal Database to compare obstetric outcomes in women with extreme obesity and those with a normal BMI (pre-pregnancy BMI 18.50 to 24.99 kg/m2). We included women with singleton gestations who gave birth between January 1, 2002, and December 31, 2011. Maternal outcomes of interest included gestational hypertension, gestational diabetes, Caesarean section, shoulder dystocia, length of hospital stay, maternal ICU admission, postpartum hemorrhage, and death. Perinatal outcomes included birth weight, preterm birth, Apgar score, neonatal metabolic abnormality, NICU admission, stillbirth, and neonatal death. A composite morbidity outcome was developed including at least one of Caesarean section, gestational hypertension, birth weight ≥ 4000 g, birth weight < 2500 g, or NICU admission. Univariate analyses and multivariate logistic regression analyses (controlling for maternal age, parity, smoking, partner status, and gestational age) were performed, and adjusted odds ratios (aORs) and 95% confidence intervals were calculated. RESULTS: A total of 5788 women were included in the study: 71 with extreme obesity and 5717 with a normal BMI. Extremely obese women were more likely to have gestational hypertension (19.7% vs. 4.8%) (aOR 1.56; 95% CI 1.33 to 1.82), gestational diabetes (21.1% vs. 1.5%) (aOR 2.04; 95% CI 1.74 to 2.38), shoulder dystocia (7.1% vs. 1.4%) (aOR 1.51; 95% CI 1.05 to 2.19), Caesarean section (60.6% vs. 25.0%) (aOR 1.46; 95% CI 1.29 to 1.65), length of hospital stay more than five days (excluding Caesarean section) (14.3% vs. 4.7%) (aOR 1.42; 95% CI 1.07 to 1.89), birth weight ≥ 4000 g (38.0% vs. 11.9%) (aOR 1.58; 95% CI 1.38 to 1.80), birth weight ≥ 4500 g (16.9% vs. 2.1%) (aOR 1.87; 95% CI 1.57 to 2.23), neonatal metabolic abnormality (8.5% vs. 2.0%) (aOR 1.50; 95% CI 1.20 to 1.86), NICU admission (16.9% vs. 7.8%) (aOR 1.28; 95% CI 1.07 to 1.52), stillbirth (1.4% vs. 0.2%) (aOR 1.68; 95% CI 1.00 to 2.82) and composite adverse outcome (81.7% vs. 41.5%) (aOR 1.57; 95% CI 1.35 to 1.83). CONCLUSION: Women with extreme obesity have increased risks of a variety of adverse maternal and perinatal outcomes. As approximately 6 per 1000 women giving birth in our population have extreme obesity, it is important to address these risks pre-conceptually and encourage a healthier BMI before pregnancy.

Objectif : Évaluer les effets de l'obésité extrême (IMC prégrossesse ≥ 50,0 kg/m2) pendant la grossesse sur les issues maternelles et périnatales. Méthodes : Nous avons mené une étude de cohorte en population générale au moyen de la Newfoundland and Labrador Perinatal Database en vue de comparer les issues obstétricales des femmes présentant une obésité extrême à celles des femmes dont l'IMC est normal (IMC prégrossesse allant de 18,50 à 24,99 kg/m2). Nous avons inclus les femmes qui connaissaient une grossesse monofœtale et qui ont accouché entre le 1er janvier 2002 et le 31 décembre 2011. Parmi les issues maternelles d'intérêt, on trouvait l'hypertension gestationnelle, le diabète gestationnel, la césarienne, la dystocie de l'épaule, la durée de l'hospitalisation, l'admission à l'unité maternelle de soins intensifs, l'hémorragie postpartum et la mort. Parmi les issues périnatales, on trouvait le poids de naissance, l'accouchement préterme, l'indice d'Apgar, les anomalies métaboliques néonatales, l'admission à l'UNSI, la mortinaissance et le décès néonatal. Une issue composite en matière de morbidité a été élaborée; on y retrouve au moins un des facteurs suivants : césarienne, hypertension gestationnelle, poids de naissance ≥ 4 000 g, poids de naissance < 2 500 g ou admission à l'UNSI. Des analyses univariées et des analyses de régression logistique multivariée (neutralisant l'effet de l'âge maternel, de la parité, du tabagisme, de l'état quant à la présence ou non d'un partenaire et de l'âge gestationnel) ont été menées, et des rapports de cotes corrigés (RCc) et des intervalles de confiance à 95 % ont été calculés. Résultats : Au total, 5 788 femmes ont été incluses à l'étude : 71 présentant une obésité extrême et 5 717 présentant un IMC normal. Les femmes extrêmement obèses étaient plus susceptibles de connaître ce qui suit : hypertension gestationnelle (19,7 % vs 4,8 %) (RCc 1,56; IC à 95 %, 1,33 - 1,82), diabète gestationnel (21,1 % vs 1,5 %) (RCc 2,04; IC à 95 %, 1,74 - 2,38), dystocie de l'épaule (7,1 % vs 1,4 %) (RCc 1,51; IC à 95 %, 1,05 - 2,19), césarienne (60,6 % vs 25,0 %) (RCc 1,46; IC à 95 %, 1,29 - 1,65), hospitalisation de plus de cinq jours (cas de césarienne exclus) (14,3 % vs 4,7 %) (RCc 1,42; IC à 95 %, 1,07 - 1,89), poids de naissance ≥ 4 000 g (38,0 % vs 11,9 %) (RCc 1,58; IC à 95 %, 1,38 - 1,80), poids de naissance ≥ 4 500 g (16,9 % vs 2,1 %) (RCc 1,87; IC à 95 %, 1,57 - 2,23), anomalie métabolique néonatale (8,5 % vs 2,0 %) (RCc 1,50; IC à 95 %, 1,20 - 1,86), admission à l'UNSI (16,9 % vs 7,8 %) (RCc 1,28; IC à 95 %, 1,07 - 1,52), mortinaissance (1,4 % vs 0,2 %) (RCc 1,68; IC à 95 %, 1,00 - 2,82) et issue indésirable composite (81,7 % vs 41,5 %) (RCc 1,57; IC à 95 %, 1,35 - 1,83). Conclusion : Les femmes qui présentent une obésité extrême sont exposées à des risques accrus de connaître une variété d'issues indésirables maternelles et périnatales. Puisque, au sein de notre population, environ six parturientes sur 1 000 présentent une obésité extrême, il est important de traiter de ces risques avant la conception et d'inciter les patientes à obtenir un IMC plus santé avant de devenir enceintes.

From Dyspnea to Skin Grafting: The Difficulties of Managing a Patient with Extreme Obesity.

While the prevalence of severe obesity is increasing worldwide, caregivers are often challenged with the management of patients with extreme weight. A 30-year-old woman (weight 245 kg, body mass index 85 kg/m2) presented with dyspnea, for which investigations led to suspect pulmonary embolism. The patient's weight made it impossible to perform adapted imaging; thus, an empirical anticoagulant treatment was initiated. A hematoma of the thigh occurred as a consequence of a transient antivitamin K overdose, leading to a 15-cm necrotic wound worsened by a state of malnutrition. Multidisciplinary and comprehensive care was performed including wound trimming, antibiotics, skin grafting, treatment of malnutrition, and psychological support, but with marked difficulties due to the lack of adapted medical equipment and facilities as well as appropriate medical guidelines. Overall, 7 months of hospitalization including 4 months of physiotherapy and rehabilitation were needed before the patient could return home. This case highlights how difficult managing patients with extreme obesity can be and points to the importance for healthcare systems to adapt to the specific needs of these patients and to design specific guidelines for treatment dosage and malnutrition prevention and treatment in this setting.

Quality of Life, Pedobarographic Parameters, and Foot Disorders in Patients with Extreme Obesity: Preliminary Results on Changes After Bariatric Surgery with Gastric Bypass.

PURPOSE: Obesity is a growing health problem that affects a high percentage of the population. In podiatry context, few studies have addressed obesity because most pedobarographic systems are unable to bear the weight of patients with obesity, making it difficult to examine and manage these patients. The objective of this study was analyzed the sociodemographic characteristics, quality of life, foot disorders, and pedobarographic parameters of patients with extreme obesity who are candidates for bariatric surgery and determine the changes after weight loss post-surgery. MATERIALS AND METHODS: We conducted a foot examination, a pedobarographic study using a Podoprint® pressure platform, and a quality of life questionnaire (EQ-5D) on 23 patients with extreme obesity and analyzed the changes 12-18 months after surgery in 11 of them. RESULTS: We observed foot disorders, high plantar pressure, greater rearfoot contact, flat footprint, asymmetries, and alterations in toe contact. Almost 73.9% of participants said they had foot pain, 56.5% said they had impaired mobility, and more than 40% said they had limitations in carrying out daily activities and suffered from anxiety. After weight loss, we observed improved quality of life; more foot disorders; changes in total contact area, plantar pressures, barycenter, contact time, and footprint; decreased pain perception, walking problems and anxiety situations. Moreover, medication decreased, but they need to take more vitamins and calcium. CONCLUSION: Weight loss improved the quality of life of the participating patients but altered their foot disorders. All parameters need regular reassessment to detect changes and modify initially prescribed treatments.

Effects of Whey Protein, Omega-3 Fatty Acid and Roux-En-Y Gastric Bypass on Body Weight, Biochemical Parameters and Organ Functions in an Obese Rat Model: Experimental Research.

PURPOSE: Extreme obesity (EO) is one of the biggest public health problems in the world and has grown considerably over the years. The aim of the study is to examine the effect of Roux-en-Y gastric bypass (RYGB), whey protein (WP), and omega-3 polyunsaturated fatty acid (PUFA) supplementation applied to EO rats on weight loss, histopathological changes in internal organs and biochemical alterations. MATERIALS AND METHODS: Wistar albino female rats (n = 28) were used in the study and randomly divided into four groups. All rats were made obese by adding high fructose corn syrup (HFCS) to their drinking water. After the EO, WP and omega-3 PUFA supplementation was given and RYGB process was applied. At the end of the study, glucose, total cholesterol, HDL, VLDL, AST, ALT and uric acid changes and liver, kidney and pancreatic tissues were evaluated histopathologically. RESULTS: WP and omega-3 PUFA supplementation decreased body weight (p > 0.05). Omega-3 PUFA and RYGB caused a decrease in total cholesterol (p < 0.05), WP decreased HDL (p < 0.05), WP and omega-3 PUFA caused an increase in ALT (p < 0.05). WP has been shown to have greater curative effects in rat liver and kidney tissues. It has been determined that RYGB causes necrosis in the liver and HFCS causes inflammation in the kidney. CONCLUSION: In the study; the positive effects of WP, omega-3 PUFA and bariatric surgery on obesity and dyslipidemia have been demonstrated. With this result, it was determined that WP, omega-3 PUFA supplementation and bariatric surgery were not superior to each other.

Clinical outcomes and complications of single anastomosis duodenal-ileal bypass with sleeve gastrectomy: A 2-year follow-up study in Bogotá, Colombia.

BACKGROUND: The global prevalence of obesity has increased over the past 40 years, and bariatric surgery has proven to be the most effective therapy for long-term weight loss. Its principles are based on modifying the brain-gut axis by altering the gastrointestinal anatomy and affecting the function of gastrointestinal hormones, thereby modifying satiety signals. Single anastomosis duodeno-ileal bypass with sleeve gastrectomy (SADI-S) combines both techniques and has become an alternative to gastric bypass and biliopancreatic diversion procedures for treating severe obesity and associated metabolic diseases in selected patients. AIM: To describe the outcomes and complications of SADI-S. METHODS: We retrospectively analyzed the data of patients who underwent SADI-S laparoscopically at the Clínica Reina Sofía in Bogotá, Colombia. This study assessed the therapeutic effectiveness of SADI-S in terms of short-term preoperative clinical characteristics, postoperative complications, comorbidities, nutritional defi-ciencies, and intraoperative complications during a 2-year follow-up. RESULTS: Sixty-one patients with a mean body mass index (BMI) of 50 ± 7.1 kg/m2 underwent laparoscopic SADI-S. The mean operative time and hospital stays were 143.8 ± 42 min and 2.3 ± 0.8 d, respectively. The mean follow-up period was 18 mo, and the mean BMI decreased to 28.5 ± 12.2 kg/m2. The excess BMI loss was 41.8% ± 13.5%, and the weight loss percentage was 81.1% ± 17.0%. Resolution of obesity-related comorbidities, including type 2 diabetes mellitus, hypertension, dyslipidemia, and obstructive sleep apnea, was achieved and defined as complete or partial remission. No intraoperative complications were observed. Short-term complications were observed in four (6.8%) patients. However, larger studies with longer follow-up periods are required to draw definitive conclusions. CONCLUSION: SADI-S has a low intraoperative and postoperative complication rate and is effective for weight loss and improving obesity-related comorbidities, including hypertension, type 2 diabetes mellitus, dyslipidemia, and sleep apnea syndrome.

Weight Loss Effects of Glucagon-Like Peptide-One Receptor Analog Treatment in a Severely Obese Patient During Hospital Admission.

Obesity is considered an independent risk factor for increased hospital length of stay and can be an obstacle to a safe discharge. Although typically prescribed in the outpatient setting, initiating glucagon-like peptide-one receptor agonists (GLP-1RAs) in the inpatient setting can be efficacious in reducing weight and increasing functional status. We report the use of GLP-1RA therapy with liraglutide and subsequent transition to subcutaneous semaglutide weekly in a 37-year-old female with severe obesity, weighing 694 lbs (314 kg) with a body mass index (BMI) of 108 kg/m2. Multiple medical and socioeconomic factors impaired the patient from being safely discharged and ultimately led to prolonged hospitalization. The patient received 31 consecutive weeks of GLP-1RA therapy in the inpatient setting along with a very low-calorie diet (800 kcal/day). Initiation and up-titration doses were completed using liraglutide for a total of five weeks. Subsequently, the patient was transitioned to receive weekly semaglutide and completed 26 weeks of therapy. At the end of week 31, the patient's weight decreased by 174 lbs (79 kg), or 25% of baseline weight, and BMI decreased from 108 to 81 kg/m2. GLP-1RAs offer a promising avenue for weight loss interventions in patients with severe obesity in addition to lifestyle modifications. The weight loss observed in our patient at the halfway point of the total treatment duration is a milestone in the pathway to gaining functional independence and meeting the criteria for future bariatric surgery. Semaglutide, a GLP-1RA, can be an effective intervention for severely obese patients with BMI greater than 100 kg/m2.

A Call to Action: Hypertensive Crises, Non-ST-Elevation Myocardial Infarction (NSTEMI), and Heart Failure in the Early Twenties.

A 21-year-old obese male with multiple hypertensive crises was diagnosed with non-ST-elevation myocardial infarction (NSTEMI), leading to heart failure due to uncontrolled hypertension and medication noncompliance. The patient's morbid obesity likely contributed to undiagnosed chronic hypertension, increasing the risk of atherosclerosis and cardiovascular diseases. Morbid obesity leads to increased interleukin-6 levels, promoting plaque accumulation and rupture. Obesity also triggers a pro-inflammatory and prothrombotic state, characterized by elevated levels of serum high-sensitivity C-reactive protein (hs-CRP), plasminogen activator inhibitor 1 (PAI-1), and other cytokines. This inflammatory state contributes to atherosclerosis development and renders plaques more prone to rupture. Additionally, obesity has been shown to increase the size of coronary thrombosis once the plaque ruptures. Treating obesity is crucial for the patient's well-being and reduces the burden on healthcare systems and society. Establishing a strong physician-patient relationship is essential for motivating lifestyle modifications, which are often the primary treatment approach for obesity and its complications.

Distribution and Association of Cardiometabolic Risk Factors Among Youth From Al Ain City, United Arab Emirates.

AIM: The purpose of this study was to examine the distribution of cardiometabolic risk factors (CMRF) among UAE University students. METHODS: The present study employed a cross-sectional design to investigate the characteristics of a sample of young individuals aged 17-26 years. The participants were exclusively drawn from the student population of UAE University. Anthropometric measurements, including weight, height, blood pressure, and random blood collection, were conducted. The statistical methods employed for comparison included the Chi-square test, Fisher's exact test, and either the two-sample t-test or the Wilcoxon rank sum test. Logistic models, both adjusted and unadjusted, were utilized to evaluate the correlation between excessive body weight and various cardiovascular and metabolic risk factors (CMRFs). All P-values were calculated using a two-sided test, and a significance level of P < 0.05 was used to determine statistical significance. The statistical computing and graphics software R (version 4.2.2) was utilized to perform all data analyses. RESULTS: Among the 269 individuals who took part in the study, a significant proportion of 55% (n=148) were identified as males. Additionally, 36% (n=97) of the participants reported having a family history of hypertension. It is worth noting that the total sample consisted of younger individuals, with a mean age of 19 years (standard deviation ±1.8). There was a significant association between overweight/obesity and male gender (p=0.003), as well as having a family history of heart attack (p=0.038), high lipid profile, and high-sensitivity C-reactive protein (hs-CRP). There was no observed correlation between a family history of hypertension and HbA1C levels in individuals with a non-normal weight. substantially elevated cardiometabolic risk variables, including systolic blood pressure (SBP) equal to or greater than 130 mmHg, diastolic blood pressure (DBP) equal to or greater than 80 mmHg, triglyceride (TG) levels equal to or greater than 150 mg/dL, high-density lipoprotein cholesterol (HDL-C) levels equal to or less than 35 mg/dL, apolipoprotein B (Apo B) levels equal to or greater than 1.3 g/L, and high-sensitivity C-reactive protein (hs-CRP) levels equal to or more than 1 mg/L, were observed to be substantially more prevalent in individuals with excess body weight compared to those with normal weight. Furthermore, the likelihood of having low HDL levels is observed to increase by 14% (Adjusted Odds Ratio = 1.14, 95% Confidence Interval [1.07 to 1.23]) among students who have extra body weight, while accounting for age and gender as controlling factors. CONCLUSIONS: Excess body weight, already in youth, was associated with increased CMRF, particularly high SBP and TG plus low HDL-C.

Internalized weight stigma in women with class III obesity: A randomized controlled trial of a virtual lifestyle modification intervention followed by a mindful self-compassion intervention.

Background: Internalized weight stigma (Internalized-WS) is prevalent among individuals with severe obesity, particularly women, and is associated with shame, disordered eating, and weight gain. Effective, accessible interventions that address both severe (Class-III) obesity and Internalized-WS are needed. This randomized pilot trial evaluated the feasibility, acceptability, and preliminary efficacy of a fully-remote lifestyle modification intervention (LM) followed by mindful self-compassion training (MSC) or control. Methods: Twenty-eight women with Class-III obesity (46.6 ± 3.7 kg/m2) and elevated Internalized-WS were randomized to a virtually-delivered 4-month LM followed by a 2-month MSC or cooking/dietary education (CON). Psychosocial measures/weight were assessed at baseline, 4-(post-LM), 6-(post-MSC/CON), and 9-month (follow-up). Results: Improvements in Internalized-WS, shame, and self-compassion were observed with LM. Mean 4-month weight loss was 6.3 ± 3.7%. MSC had lower attendance and usefulness ratings versus CON. Post-MSC/CON, MSC yielded significant and/or meaningful improvements in Internalized-WS, self-compassion, and intuitive eating relative to CON. Weight loss did not differ by group at 6-month, and at 9-month trended lower in MSC versus CON. Conclusion: Virtual LM is feasible, acceptable, and leads to significant weight loss among women with severe obesity; MSC led to further improved Internalized-WS, self-compassion, and intuitive eating. Continued work is needed to elucidate effects of self-compassion training on Internalized-WS, its mechanisms, and linkages to cardiometabolic health and long-term weight loss.
