Early Exercise Through Telerehabilitation After Bariatric Surgery: Is It Feasible?

PURPOSE: The feasibility of early telerehabilitation after bariatric surgery is unknown. The objective of this study was to assess the feasibility and perception of engaging in the online exercise protocol in patients during the first month after bariatric surgery. MATERIAL AND METHODS: A total of 67 patients, enrolled in a telerehabilitation program following bariatric surgery, completed a survey assessing their perception of the intensity, discomfort, and safety during exercise sessions. RESULTS: Forty percent of participants began exercising between 5 and 10 days after surgery. Seventy-one percent of patients did not experience discomfort during the first month of exercise, and those who reported discomfort mainly mentioned dizziness and abdominal pain. No significant differences were found in the presence of discomfort among different types of surgeries performed. There was a significant difference in the presence of discomfort between patients who started exercising before and after 15 days of surgery, with less discomfort reported in the group that started after 15 days. Ninety-eight percent of patients felt safe during online exercise sessions. Most participants perceived the intensity of the sessions as moderate. The most frequently mentioned benefits of exercise were increased energy, mood, and feeling more active. CONCLUSION: Telerehabilitation conducted during the first month after bariatric surgery was feasible and well tolerated by patients, providing a safe alternative for those patients who face difficulties with in-person interventions.

Efficacy of telehealth core exercises during COVID-19 after bariatric surgery: a randomized controlled trial.

BACKGROUND: Bariatric surgery (BS) is presently the most durable and effective intervention to address severe obesity. BS results in significant weight loss and body composition changes, with reductions in both fat mass and lean mass. Conequently, muscle tissue wasting and a reduction in muscle strength and endurance seem to take place. Some studies have evaluated the impact of resistance training on changes in lean body mass and muscle strength either alone or along with protein supplementation in the first year after BS. However, the effects of core stabilization training on core endurance, postural control, and aerobic capacity in patients after BS have not been evaluated. AIM: This study assessed the effect of a home telehealth core stabilization exercise program on core stability, postural control, and aerobic capacity in patients after BS. DESIGN: A single-blinded randomized controlled trial. SETTING: Home-based exercise program. POPULATION: Patients after BS. METHODS: Fifty-four patients who underwent BS randomly assigned into study and control groups. The study group followed a telehealth supervised home core stabilization program for 8 weeks, while the control group did not receive any form of exercises. Core endurance tests, postural stability, and aerobic capacity were assessed at baseline and after 8 weeks in both groups. RESULTS: No significant difference was noted between groups at baseline (P>0.05). The outcome of the group comparisons showed significant improvement in core endurance tests, postural stability, and aerobic capacity in the study group. Between groups comparision showed that the study group scores significantly higher than the control group (P<0.05). However, the control group showed non-significant changes in any measured variables after eight weeks (P>0.05). CONCLUSIONS: Eight weeks of a home-based telehealth core exercise program improves core endurance, postural stability, and aerobic capacity in patients after BS. CLINICAL REHABILITATION IMPACT: The core stabilization exercise is an important rehabilitation program that should be implemented after BS. Telehealth is an alternative rehabilitation tool during the COVID -19 pandemic.

Impact of a Mobile App to Support Home Recovery of Patients Undergoing Bariatric Surgery.

BACKGROUND: Perioperative patient education and engagement are critical components of care in patients undergoing bariatric surgery, given the short length of stay and the requirements to adhere to various instructions. The use of patient engagement mobile technology may promote adherence to perioperative protocols and improve care by potentially identifying complications earlier and reducing associated health care costs. MATERIALS AND METHODS: We introduced a mobile app that provides bariatric patients with access to educational materials and the ability to report on their symptoms. Using the data from the app and linking the data to patient outcomes collected in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database, we examined the effects of the app on readmission, length of stay, visits to the emergency department (ED), and patient satisfaction. RESULTS: A total of 505 patients were enrolled in the app between July 2017 and March 2019. Among them, 396 patients who met the inclusion criteria for the study were compared with 458 patients in the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database who were not enrolled in the app for the same study period. While the use of the app was not associated with the rates of prolonged length of stay, ED visits, and readmission, patients who completed a survey at 30 d after discharge reported that the app helped them avoid phone calls to the hospital (48.5%) and ED visits (13.0%). Furthermore, 94.8% of these patients reported that they would recommend the app to other patients undergoing the same surgery. CONCLUSIONS: Additional features, such as the ability for patients to directly communicate with the health care providers within the app, may be effective in decreasing unnecessary health care utilization.

Determinants of Cardiorespiratory Fitness After Bariatric Surgery: Insights From a Randomised Controlled Trial of a Supervised Training Program.

BACKGROUND: Severely obese patients have decreased cardiorespiratory fitness (CRF) and poor functional capacity. Bariatric surgery-induced weight loss improves CRF, but the determinants of this improvement are not well known. We aimed to assess the determinants of CRF before and after bariatric surgery and the impact of an exercise training program on CRF after bariatric surgery. METHODS: Fifty-eight severely obese patients (46.1 ± 6.1 kg/m2, 78% women) were randomly assigned to either an exercise group (n = 39) or usual care (n = 19). Exercise training was conducted from the 3rd to the 6th months after surgery. Anthropometric measurements, abdominal and mid-thigh computed tomographic scans, resting echocardiography, and maximal cardiopulmonary exercise testing was performed before bariatric surgery and 3 and 6 months after surgery. RESULTS: Weight, fat mass, and fat-free mass were reduced significantly at 3 and 6 months, without any additive impact of exercise training in the exercise group. From 3 to 6 months, peak aerobic power (V̇O2peak) increased significantly (P < 0.0001) in both groups but more importantly in the exercise group (exercise group: from 18.6 ± 4.2 to 23.2 ± 5.7 mL/kg/min; control group: from 17.4 ± 2.3 to 19.7 ± 2.4 mL/kg/min; P value, group × time = 0.01). In the exercise group, determinants of absolute V̇O2peak (L/min) were peak exercise ventilation, oxygen pulse, and heart rate reserve (r2 = 0.92; P < 0.0001), whereas determinants of V̇O2peak indexed to body mass (mL/kg/min) were peak exercise ventilation and early-to-late filling velocity ratio (r2 = 0.70; P < 0.0001). CONCLUSIONS: A 12-week supervised training program has an additive benefit on cardiorespiratory fitness for patients who undergo bariatric surgery.

A cirurgia bariátrica como intervenção segura e eficaz para o controle de comorbidades em idosos / Bariatric surgery as a safe and effective intervention for the control of comorbidities in older adults

INTRODUÇÃO: A obesidade no idoso, além de estar associada à piora de doenças relacionadas à síndrome metabólica e a distúrbios osteoarticulares, aumenta o risco de quedas, síndrome de fragilidade, depressão e demência, com consequente perda de funcionalidade. Entre todos os tratamentos disponíveis, a cirurgia bariátrica é uma alternativa em pacientes elegíveis. OBJETIVOS: Discutir aspectos relacionados à segurança e aos benefícios da cirurgia bariátrica para o controle ou a remissão de comorbidades no idoso. METODOLOGIA: Foi realizada revisão de literatura em bases de dados utilizando os seguintes descritores: bariatric surgery and elderly or aged or older adult and comorbidities or safety. Foram incluídos ensaios clínicos, estudos observacionais, estudos comparativos e revisões que avaliaram o efeito da cirurgia bariátrica no controle ou na remissão de comorbidades em idosos. RESULTADOS: Nos últimos anos, vários estudos têm demonstrado não apenas controle ou remissão de comorbidades como diabetes, hipertensão e síndrome da apneia do sono, mas também reduzida taxa de complicações, semelhante à observada em jovens. CONCLUSÕES: Com base nos resultados desses estudos, há espaço para que procedimentos de cirurgia bariátrica sejam indicados a idosos elegíveis, sem limite de idade, considerando também aspectos funcionais e de expectativa de vida.

INTRODUCTION: In addition to being associated with worsening of diseases related to metabolic syndrome and musculoskeletal disorders, obesity in older adults increases the risk of falls, frailty syndrome, depression, and dementia, with consequent functional loss. Among all treatments available, bariatric surgery is an option for eligible patients. OBJECTIVES: To discuss aspects related to the safety and benefits of bariatric surgery for the control or remission of comorbidities in older adults. METHODS: This literature review was carried out in databases, using the following keywords: bariatric surgery and elderly or aged or older adult and comorbidities or safety. We included clinical trials, observational studies, comparative studies, and reviews that evaluated the effect of bariatric surgery on the control or remission of comorbidities in older adults. RESULTS: In recent years, several studies have evidenced not only control or remission of comorbidities, such as diabetes, hypertension, and sleep apnea syndrome, but also a low rate of complications, similar to those observed in young people. CONCLUSIONS: Based on the results of these studies, bariatric surgical procedures can be indicated for eligible older adults, without age restriction, taking into account functional and life expectancy aspects.

Comparison of Preoperative Remission Scores and Diabetes Duration Alone as Predictors of Durable Type 2 Diabetes Remission and Risk of Diabetes Complications After Bariatric Surgery: A Post Hoc Analysis of Participants From the Swedish Obese Subjects Study.

OBJECTIVE: Bariatric surgery is associated with diabetes remission and prevention of diabetes-related complications. The ABCD, DiaRem, Ad-DiaRem, DiaBetter, and individualized metabolic surgery scores were developed to predict short- to medium-term diabetes remission after bariatric surgery. However, they have not been tested for predicting durable remission nor the risk of diabetes complications, nor compared with diabetes duration alone. RESEARCH DESIGN AND METHODS: We identified 363 individuals from the surgically treated group in the prospective Swedish Obese Subjects study with preoperative type 2 diabetes and for whom data (preoperative age, BMI, C-peptide, HbA1c, oral diabetes medications, insulin use, and diabetes duration) were available for calculation of remission scores. Partial remission (after 2 and 10 years) was defined as blood glucose <6.1 mmol/L or HbA1c <6.5% (48 mmol/mol) and no diabetes medication. Information on diabetes complications (at baseline and over 15 years of follow-up) was obtained from national health registers. Discrimination was evaluated by area under receiver operating characteristic curves (AUROCs). RESULTS: For 2-year diabetes remission, AUROCs were between 0.79 and 0.88 for remission scores and 0.84 for diabetes duration alone. After 10 years, the predictive ability of scores decreased markedly (AUROCs between 0.70 and 0.76), and no score had higher predictive capacity than diabetes duration alone (AUROC = 0.73). For development of microvascular and macrovascular diabetes complications over 15 years, AUROCs for remission scores were 0.70-0.80 and 0.62-0.71, respectively, and AUROCs for diabetes duration alone were 0.77 and 0.66, respectively. CONCLUSIONS: Remission scores and diabetes duration are good predictors of short-term diabetes remission. However, for durable remission and risk of complications, remission scores and diabetes duration alone have limited predictive ability.

The role of speech therapist in the patient care team for bariatric surgery / Rol del fonoaudiólogo en el equipo de atención al paciente para cirugía bariátrica

The work of the speech therapist with patients undergoing Bariatric Surgery (BS) is still little explored, although essential for the adequate preparation of the subject for surgery, as well as for his short and long term recovery. Given its importance and it's still limited performance in this scenario, the objective of this study was to verify the perception of patients about the importance and effectiveness of speech therapy both in the pre and postoperative period of BS. Questionnaires were carried out with 44 patients divided into 4 groups, according to the moment of bariatric surgery follow-up. Most of the subjects were unaware of the role of the speech therapist at the beginning of the treatment, but they considered their guidance and their presence in the team relevant during the process. The ignorance of the role of the Speech-Language Pathologist in the care of bariatric patients is related to the incipient participation of Speech-Language Pathologists in this scenario. The positive impact of speech therapy guidelines in the preoperative period improves quality of life, provides information and clarifies subjects' doubts and fears, enhancing results and minimizing postoperative problems. The professional's guidance in relation to the aspects experienced in the patients' daily lives implies a consensus on the importance of the participation of the Speech Therapist during the process of monitoring the BS. Patients' perception of the importance of the guidelines received by the Speech-Language Pathologist was well-known, as well as their necessary participation in the multidisciplinary team. The results demonstrated the effectiveness of speech therapy both in the pre and in the short and long term postoperative period.

La labor del fonoaudiólogo con pacientes sometidos a Cirugía Bariátrica (CB) es aún poco explorada, aunque fundamental para la adecuada preparación del sujeto para la cirugía, así como para su recuperación a corto y largo plazo. Dada su importancia y su aún limitado desempeño en este escenario, el objetivo de este estudio fue verificar la percepción de los pacientes sobre la importancia y efectividad de la logopedia tanto en el período pre como postoperatorio de CB. Se realizaron cuestionarios con 44 pacientes divididos en 4 grupos, según el momento del seguimiento de la cirugía bariátrica. Resultados: La mayoría de los sujetos desconocían el rol del fonoaudiólogo al inicio del tratamiento, pero consideraron relevante su orientación y presencia en el equipo durante el proceso. El desconocimiento del papel del fonoaudiólogo en la atención de los pacientes bariátricos se relaciona con la incipiente participación de los fonoaudiólogos en este escenario. El impacto positivo de las pautas de fonoaudiología en el período preoperatorio mejora la calidad de vida, brinda información y aclara las dudas y temores de los sujetos, potenciando los resultados y minimizando los problemas postoperatorios. La orientación del profesional en relación con los aspectos vividos en la vida diaria de los pacientes implica un consenso sobre la importancia de la participación del fonoaudiólogo durante el proceso de seguimiento de CB. Es conocida la percepción de los pacientes sobre la importancia de las guías recibidas por el fonoaudiólogo, así como su necesaria participación en el equipo multidisciplinario. Los resultados demostraron la eficacia de la fonoaudiología tanto en el pre como en el postoperatorio a corto y largo plazo.

Diet approach before and after bariatric surgery.

Bariatric surgery (BS) is today the most effective therapy for inducing long-term weight loss and for reducing comorbidity burden and mortality in patients with severe obesity. On the other hand, BS may be associated to new clinical problems, complications and side effects, in particular in the nutritional domain. Therefore, the nutritional management of the bariatric patients requires specific nutritional skills. In this paper, a brief overview of the nutritional management of the bariatric patients will be provided from pre-operative to post-operative phase. Patients with severe obesity often display micronutrient deficiencies when compared to normal weight controls. Therefore, nutritional status should be checked in every patient and correction of deficiencies attempted before surgery. At present, evidences from randomized and retrospective studies do not support the hypothesis that pre-operative weight loss could improve weight loss after BS surgery, and the insurance-mandated policy of a preoperative weight loss as a pre-requisite for admission to surgery is not supported by medical evidence. On the contrary, some studies suggest that a modest weight loss of 5-10% in the immediate preoperative period could facilitate surgery and reduce the risk of complications. Very low calories diet (VLCD) and very low calories ketogenic diets (VLCKD) are the most frequently used methods for the induction of a pre-operative weight loss today. After surgery, nutritional counselling is recommended in order to facilitate the adaptation of the eating habits to the new gastro-intestinal physiology. Nutritional deficits may arise according to the type of bariatric procedure and they should be prevented, diagnosed and eventually treated. Finally, specific nutritional problems, like dumping syndrome and reactive hypoglycaemia, can occur and should be managed largely by nutritional manipulation. In conclusion, the nutritional management of the bariatric patients requires specific nutritional skills and the intervention of experienced nutritionists and dieticians.

Bariatric surgery: postoperative management

Adherence to consistent post-operative behavioural changes (behaviour modification for nutrition plans, physical activity and vitamin intake) can optimize obesity management and health while minimizing post-operative complications. Working in partnership, the bariatric surgical centre, the local bariatric medicine specialist, the primary care provider and the patient living with obesity need to establish and commit to a shared care model of chronic disease manage­ment for long-term follow-up. The primary care provider should refer patients with post-bariatric surgery complications back to the bariatric surgical centre, or to a local bariatric medicine specialist.

Enhanced recovery after surgery among adolescents undergoing bariatric surgery.

Enhanced recovery after surgery (ERAS) has evolved over the past two decades. Originally aimed to standardize care among adults undergoing colorectal surgery, the tenets that developed have since been broadly accepted by a large number of adult surgical subspecialties, including bariatric surgery. This multidisciplinary, patient-centered approach involving optimizing pre-, intra-, and postoperative phases of care has resulted in shorter hospitalizations, fewer complications, and lower mortality rates. Recently, multiple pediatric surgery subspecialties have adopted ERAS principles and have documented similar favorable outcomes. Among adolescent bariatric patients, outcomes following the implementation of ERAS have not yet been described. We will review the history and goals of ERAS and detail pediatric surgery specific implementations. We will also review outcomes associated with ERAS within specific pediatric surgical subspecialties. Lastly, we will discuss the current ERAS protocol developed at Children's Hospital Colorado for adolescent bariatric surgery.

Physical Exercise following bariatric surgery in women with Morbid obesity: Study protocol clinical trial (SPIRIT compliant).

BACKGROUND: Severe and morbid obesity are increasing globally, particularly in women. As BMI increases, the likelihood of anovulation is higher. The primary aim of the EMOVAR clinical trial is to examine, over the short (16 weeks) and medium (12 months) term, the effects of a supervised physical exercise program (focused primarily on aerobic and resistance training) on ovarian function in women with severe/morbid obesity who have undergone bariatric surgery. Secondary objectives are to examine the effects of the intervention on chronic inflammation, insulin resistance, arterial stiffness, physical fitness, and health-related quality of life. METHODS: This is a randomized controlled trial in which ∼40 female bariatric surgery patients, aged between 18 and 45 years old, will be included. Participants assigned to the experimental group will perform a total of 48 sessions of supervised concurrent (strength and aerobic) training (3 sessions/week, 60 min/session) spread over 16 weeks. Patients assigned to the control group will receive lifestyle recommendations. Outcomes will be assessed at baseline, week 16 (i.e., after the exercise intervention) and 12 months after surgery. The primary outcome is ovarian function using the Sex-Hormone Binding Globuline, measured in serum. Secondary outcomes are serum levels of anti-mullerian hormone, TSH, T4, FSH, LH, estradiol, prolactine, and free androgen index, as well as oocyte count, the diameters of both ovaries, endometrial thickness, and uterine arterial pulsatility index (obtained from a transvaginal ultrasound), the duration of menstrual bleeding and menstrual cycle duration (obtained by personal interview) and hirsutism (Ferriman Gallwey Scale). Other secondary outcomes include serum markers of chronic inflammation and insulin resistance (i.e., C-reactive protein, interleukin 6, tumor necrosis factor-alpha, leptin, glomerular sedimentation rate, glucose, insulin and the HOMA-IR), arterial stiffness, systolic, diastolic and mean blood pressure, body composition, and total weight loss. Physical fitness (including cardiorespiratory fitness, muscular strength, and flexibility), health-related quality of life (SF-36 v2) and sexual function (Female Sexual Function Index) will also be measured. DISCUSSION: This study will provide, for the first time, relevant information on the effects of exercise training on ovarian function and underlying mechanisms in severe/morbid obese women following bariatric surgery. TRIAL REGISTRATION NUMBER: ISRCTN registry (ISRCTN27697878).

Improvement in arterial stiffness (pOpmètre®) after bariatric surgery. Results from a prospective study.

BACKGROUND: Arterial stiffness (AS) is an independent predictor of cardiovascular risk, and could be used as a surrogate marker of improvement in cardiovascular risk following bariatric surgery. The aim of this study was to compare AS before and after surgery. METHODS: One hundred and thirty-four patients undergoing bariatric surgery between May 2016 and January 2019 were prospectively included. AS was measured on pulse wave velocity (PWV) with the pOpmètre® device pre- and postoperatively. The main endpoint was change in PWV between baseline and 3 months post-surgery. RESULTS: Overall, mean PWV was 6.87m/s preoperatively and 6.71m/s at 3 months (P=0.7148). Patients with pathologic PWV (>2 standard deviations from expected value for age) showed significant improvement at 3 months (31 patients; 10.1m/s preoperatively vs 7.5m/s at 3 months; P=0.007). These results did not correlate with improvement in other clinical or biological parameters following surgery (excess weight loss, mean blood pressure, fasting blood glucose, waist circumference, body composition). CONCLUSION: These results suggest that pathological arterial stiffness may resolve following bariatric surgery independently of the other factors influencing cardiovascular risk in obesity.

ABSTRACT Objective: to investigate the factors associated with the sexual health of patients subjected to bariatric surgery. Methods: this is a cohort performed with 387 patients who were subjected to bariatric surgery between the years 2012 and 2014, in a general and private hospital in Minas Gerais. The information was collected through electronic medical records and the telephone. Results: women (87.60%); brown (self-declared) color (49.84%); with education from 11 to 14 years (32.57%); lived with a partner (69.06%); and average income of one to three minimum wages per household (54.79%). Median age was 36 years (IQ=30-43). When analyzing the improvement in sexual performance after the surgical procedure, 214 (71.33%) of the patients highlighted improvement in this aspect. Of these, 32 (14.95%) were male and 182 (85.04%) were female. Sociodemographic factors in the studied scenario, except for age in males, showed no statistical difference in the improvement of sexual performance after bariatric surgery. Conclusion: surgical treatment can have a positive impact on the patient's sexual life and these results can alert health institutions to optimize their assistance. Thus, health professionals, especially nurses, play a fundamental role in understanding what factors are associated with improving patients' sexual lives, allowing the prevention of complaints and effective intervention measures.

Early-phase study of a telephone-based intervention to reduce weight regain among bariatric surgery patients.

OBJECTIVE: This study describes early-phase development of a behavioral intervention to reduce weight regain following bariatric surgery. We utilized the Obesity-Related Behavioral Intervention Trials model to guide intervention development and evaluation. We sought to establish recruitment, retention, and fidelity monitoring procedures; evaluate feasibility of utilizing weight from the electronic medical record (EMR) as an outcome; observe improvement in behavioral risk factors; and evaluate treatment acceptability. METHOD: The intervention comprised 4 weekly telephone calls addressing behavior change strategies for diet, physical activity, and nutrition supplement adherence and 5 biweekly calls addressing weight loss maintenance constructs. Veterans (N = 33) who received bariatric surgery 9-15 months prior consented to a 16-week, pre-post study. Self-reported outcomes were obtained by telephone at baseline and 16 weeks. Clinic weights were obtained from the EMR 6 months pre- and postconsent. Qualitative interviews were conducted at 16 weeks to evaluate treatment acceptability. We aimed to achieve a recruitment rate of ≥ 25% and retention rate of ≥ 80%, and have ≥ 50% of participants regain < 3% of their baseline weight. RESULTS: Results supported the feasibility of recruiting (48%) and retaining participants (93% provided survey data; 100% had EMR weight). Pre-post changes in weight (73% with < 3% weight regain) and physical activity (Cohen's ds 0.38 to 0.52) supported the potential for the intervention to yield clinically significant results. Intervention adherence (mean 7.8 calls of 9 received) and positive feedback from interviews supported treatment acceptability. CONCLUSIONS: The intervention should be evaluated in an adequately powered randomized controlled trial. (PsycInfo Database Record (c) 2020 APA, all rights reserved).

Opioid Use Following Bariatric Surgery: Results of a Prospective Survey.

BACKGROUND: Opioid use after bariatric surgery is not clearly understood. Few guidelines exist to inform opioid-prescribing practices after bariatric surgery. OBJECTIVE: To understand opioid use following bariatric surgery. SETTING: University hospital. METHODS: Bariatric surgery patients at a single center were prospectively surveyed at the time of their post-operative visit (January-May 2018). Patients were asked about their opioid use following surgery, whether they received education about opioid use and what they did with leftover medications. Demographic and operative details were obtained from the medical record. RESULTS: Among 33 patients, the majority (n = 29, 88%) were female with a median age of 40 (20-68) and body mass index of 44.8 (33-78.5). Most patients had leftover narcotics (n = 25, 73%). The median number of pills used was 15 (0-48). Only 12 patients (36%) thought that they had been prescribed "too much" pain medication. Most patients reported receiving education about expectations for post-operative pain (n = 22, 69%); few recalled education about reducing or stopping opioids (n = 13, 40%). More than half of patients (n = 17, 53%) kept their leftover opioids rather than disposing of them or bringing them to an approved turn in location. CONCLUSIONS: Despite most patients having leftover opioids following surgery, few patients recognized possible overprescription. Education regarding opioid use following surgery is inconsistent, potentially contributing to the amount of retained opioids currently available. Future guidelines should focus on determining the appropriate amount of opioids to be prescribed following surgery and standardizing and improving education given to patients.

Impact of Bariatric Surgery on Female Sexual Function in Obese Patients: a Meta-Analysis.

We aimed to make a meta-analysis regarding the effect of bariatric surgery on female sexual function. PubMed, EMBASE, and CENTRAL were searched from database inception through August 2019. Articles were eligible for inclusion if they examined the effect of bariatric surgery on obese women's sexual function assessed by the Female Sexual Functioning Index (FSFI) or/and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12). Twenty articles were included into meta-analysis. Bariatric surgery was associated with significant increase in the total FSFI score. When parameters included in the FSFI scoring system were separately evaluated, significant improvements were observed in sexual desire, sexual arousal, lubrication, orgasm, sexual satisfaction, and sexual pain. However, the PISQ-12 and FSFI scores in women with pelvic floor disorders (PFDs) were not significantly changed postoperatively. Bariatric surgery improves female sexual function in obese patients, but not in women with PFD.

The Influence of Body Contouring Surgery on Weight Control and Comorbidities in Patients After Bariatric Surgery.

INTRODUCTION: A considerable number of patients experience some long-term weight regain after bariatric surgery. Body contouring surgery (BCS) is thought to strengthen post-bariatric surgery patients in their weight control and maintenance of achieved improvements in comorbidities. OBJECTIVES: To examine the impact of BCS on long-term weight control and comorbidities after bariatric surgery. METHODS: We performed a retrospective study in a prospective database. All patients who underwent primary Roux-en-Y gastric bypass (RYGB) and presented for preoperative consultation of BCS in the same hospital were included in the study. Linear and logistic mixed-effect model analyses were used to evaluate the longitudinal relationships between patients who were accepted or rejected for BCS and their weight loss outcomes or changes in comorbidities. RESULTS: Of the 1150 patients who underwent primary RYGB between January 2010 and December 2014, 258 patients (22.4%) presented for preoperative consultation of BCS. Of these patients, 126 patients eventually underwent BCS (48.8%). Patients who were accepted for BCS demonstrated significant better ∆body mass index (BMI) on average over time (- 1.31 kg/m2/year, 95% confidence interval (CI) -2.52 - -0.10, p = 0.034) and percent total weight loss (%TWL) was significantly different at 36 months (5.79, 95%CI 1.22 - 10.37, p = 0.013) and 48 months (6.78, 95%CI 0.93 - 12.63, p = 0.023) after body contouring consultation. Patients who were accepted or rejected did not differ significantly in the maintenance of achieved improvements in comorbidities. CONCLUSION: BCS could not be associated with the maintenance of achieved improvements in comorbidities after bariatric surgery, whereas it could be associated with improved weight loss maintenance at 36 and 48 months after body contouring consultation. This association should be further explored in a large longitudinal study.

Association of Serum Zinc Concentration with Preservation of Renal Function After Bariatric Surgery: a Retrospective Pilot Study.

BACKGROUND: Although serum zinc level (Zn) is known to impact renal function in patients with diabetes, their correlation following bariatric surgery remains unknown. This study aimed at assessing the association of Zn with estimated glomerular filtration rate (eGFR) after laparoscopic sleeve gastrectomy (LSG). METHODS: One hundred and twenty-nine patients in total (mean age, 38.1 ± 10.8; body mass index, 39.1 ± 5.1 kg/m2) with normal preoperative kidney function undergoing LSG at a single tertiary referral center were reviewed. The primary study endpoint was the relationship between Zn and post-LSG eGFR at 12-month follow-up. The secondary outcomes were the associations of percentage weight loss (%WL) with changes in Zn (△Zn) and eGFR (△eGFR). RESULTS: The incidence of zinc deficiency was 8.5%, 8.1%, and 29.9% at baseline, post-LSG and one- and 12-month follow-up, respectively. At 12-month follow-up, Zn dropped from 104.1 ± 19.2 to 85.3 ± 38.9 µg/dL (p = 0.001), while eGFR levels decreased from 106.6 ± 10.3 to 102.1 ± 19.4 mL/min per 1.73 m2 (p = 0.025). Zn correlated positively with eGFR at 6-month (r = 0.252, p = 0.037) and 12-month (r = 0.41, p = 0.001) follow-ups. Multiple linear regression analyses including baseline variables of age, sex, BMI, %WL, and diabetes identified Zn and %WL as independent predictors of eGFR at 12-month follow-up. There was no evidence of multicollinearity among these variables. Despite positive association between %WL and △eGFR (r = 0.222, p = 0.031), no correlation was noted between %WL and △Zn (r = - 0.129, p = 0.40). CONCLUSION: The results demonstrated a positive relationship between post-LSG serum zinc levels and preservation of renal function among patients with obesity in a surgical setting. Large-scale studies are warranted to support the findings.

Elevated Levels of Circulating miR-92a Are Associated with Impaired Glucose Homeostasis in Patients with Obesity and Correlate with Metabolic Status After Bariatric Surgery.

INTRODUCTION: miRNAs are small non-coding RNAs, some of which are expressed in adipose tissues, are present in the circulation, and are regulated in obesity. Bariatric surgery (BS) has been proposed to lead to activation of brown adipose tissue, an effect that may be related to beneficial effects of BS on systemic metabolism. Here, we evaluated circulating levels of miR-92a and miR-99b, two miRNAs proposed as biomarkers of brown fat activity, in a cohort of patients with severe obesity before and after BS, and studied their potential relationship with BS-associated improvements in metabolic parameters. METHODS: Circulating levels of miR-92a and miR-99b were quantified in a cohort of 26 patients (age, 48 ± 10 years; BMI, 45 ± 7 kg/m2) before and 6 months after BS. Clinical parameters were determined at different time points and correlations among them were studied. RESULTS: Basal levels of miR-92a were significantly increased in patients with obesity relative to lean controls. Serum miR-92a levels were strongly reduced at 6 months after BS, reaching levels similar to those in controls. Serum miR-99b levels were unchanged in relation to both the obese condition and BS. Elevated levels of miR-92a were directly correlated with worsened glucose homeostasis parameters and poor BS outcome. CONCLUSIONS: Our findings show that miR-92a is elevated in conditions of obesity, and its reduction after BS correlates with metabolic improvement. Further studies would be necessary to establish miR-92a as serum biomarker and potential predictor of the BS success in improving the metabolic status of patients with obesity.

Changes in Central 24-h Ambulatory Blood Pressure and Hemodynamics 12 Months After Bariatric Surgery: the BARIHTA Study.

BACKGROUND: Weight loss is associated to blood pressure (BP) reduction in obese patients. There is no information on central 24-h BP changes after bariatric surgery (BS). METHODS AND RESULTS: In this study, we analyzed changes in 24-h BP 12 months following BS, with intermediate evaluations at 1, 3, and 6 months, in severely obese adults. The primary endpoint was aortic (central) 24-h systolic BP changes. Circadian BP patterns and hypertension resolution were also assessed. As secondary endpoints, we analyze changes in central 24-h diastolic BP as well as in all office and ambulatory peripheral BP parameters. Obese adults scheduled for BS as routine clinical care were recruited. We included 62 patients (39% with hypertension, 77% women, body mass index, 42.6 ± 5.5 kg/m2). Reduction in body weight was mean (IQR) 30.5% (26.2-34.4) 1 year after BS. Mean (95% CI) change in central 24-h systolic BP was - 3.1 mmHg (- 5.5 to - 0.7), p = 0.01 after adjustment for age, sex, and baseline hypertensive status. BP parameter changes were different between normotensives and hypertensives. Mean (95% CI) change in central 24-h systolic BP was - 5.2 mmHg (- 7.7 to - 2.7), p < 0.001, in normotensives and - 0.5 mmHg (- 5.1 to 4.0), p = 0.818, in hypertensives. There was a remission of hypertension in 48% of patients. Most patients had a reduced dipping pattern, similarly at baseline and 12 months after BS. CONCLUSIONS: Among patients with severe obesity, there was a substantial central 24-h systolic BP decrease 12 months following BS. Importantly, this change was observed in those patients with normal BP at baseline. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT03115502.
