Gothelf I, Sheiner E, Wainstock T. Maternal Bariatric Surgery and Offspring Health: A Sibling Matched Analysis Comparing Offspring Born before and after the Surgery. J Clin Med 2023; 12:jcm12093056. [PMID: 37176496 PMCID: PMC10179329 DOI: 10.3390/jcm12093056] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2023] [Revised: 04/17/2023] [Accepted: 04/20/2023] [Indexed: 05/15/2023] Open
Abstract
(1) Background: Due to the global escalation in the prevalence of obesity, bariatric surgeries have become a popular solution in many western countries. The aim of the current study was to compare offspring health and the obesity of women before and after undergoing bariatric surgeries. (2) Methods: A retrospective population-based study was performed, including all singleton deliveries which occurred at a tertiary medical center between the years 1991-2021. Among women who had bariatric surgeries, the health of the offspring born before and after the surgery were compared. The offspring were followed up until the age of 18 years, and their hospitalization records were summarized. The incidence of hospitalization with either endocrine, cardiac, respiratory, neurologic, or infectious diagnoses were compared between the groups, as well as offspring obesity. Multivariable Cox proportional models were used to match between siblings and to address confounding variables, including maternal age, gestational age at delivery, fertility treatment, smoking and pregnancy hypertensive disorders. (3) Results: The study population included 3074 deliveries of women who underwent bariatric surgeries (1586 were before and 1488 after the surgery). Offspring born after maternal bariatric surgeries were at a comparable risk for most morbidities, besides endocrine-related morbidities (3.1% vs. 5.0%, OR = 1.61; 1.1-2.35) and obesity (2.5% vs. 4.1%, OR = 1.63; 1.08-2.48). The risk for these morbidities was higher among the offspring of mothers after, vs. before, the surgery, despite adjustment for maternal age and other confounding variables. (4) Conclusions: While bariatric surgeries are considered an effective treatment for obesity, it seems to have less of an effect on the offspring of women who underwent such surgeries. Other persistent factors are most likely associated with the offspring's risk for morbidities, especially endocrine morbidities and obesity, which remain even though the mother underwent bariatric surgeries.

Pregnancy characteristics and outcomes after bariatric surgery: national-level analysis in the United States. Surg Obes Relat Dis 2023; 19:364-373. [PMID: 36470811 DOI: 10.1016/j.soard.2022.10.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2022] [Revised: 09/16/2022] [Accepted: 10/16/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Bariatric surgery is an effective surgical treatment for weight reduction in individuals with obesity. Pregnancy outcomes related to prior bariatric surgery are currently under active investigation. OBJECTIVE To assess national-level trends, characteristics, and outcomes of pregnancy after bariatric surgery in the United States. SETTING Retrospective cohort study queried the National Inpatient Sample. METHODS The study population was 14,648,135 patients who had vaginal or cesarean delivery from January 2016 to December 2019. Exposure allocation was based on the history of bariatric surgery. The main outcomes were (1) trends and characteristics related to bariatric surgery, assessed with multivariable binary logistic regression model; and (2) Centers for Disease Control and Prevention-defined severe maternal morbidity, assessed by propensity score matching and generalized estimating equation. RESULTS A total of 53,950 (.4%) patients had prior bariatric surgery. The number of patients with prior bariatric surgery increased from .3% to .5%, and this trend remained independent in multivariable analysis (P < .001). Patients who had bariatric surgery were also more likely to be older and have obesity, medical co-morbidities, fetal growth restriction, preterm birth, and cesarean delivery compared with those without bariatric surgery (all, P < .05). In a propensity score matched model, patients who had bariatric surgery were more likely to receive blood product transfusion (2.3% versus 1.6%; odds ratio = 1.45; 95% confidence interval, 1.19-1.77), but severe maternal morbidity other than blood product transfusion was comparable to those without (1.1% versus 1.4%; odds ratio = .80; 95% confidence interval, .63-1.02). CONCLUSION There is a gradual increase of pregnancy after bariatric surgery in recent years in the United States.

Brain Res Bull 2018; 138:26-36. [PMID: 28802901 PMCID: PMC6537102 DOI: 10.1016/j.brainresbull.2017.08.004] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2017] [Revised: 08/05/2017] [Accepted: 08/07/2017] [Indexed: 12/13/2022]
Abstract
Vertical sleeve gastrectomy (VSG) and Roux-en-Y gastric bypass (RYGB) are the most common surgical options for the treatment of obesity and metabolic disorder. Whereas RYGB may result in greater and more durable weight loss, recent clinical and pre-clinical studies in rats have raised concerns that RYGB surgery may increase risk for alcohol use disorder (AUD). In contrast, recent clinical reports suggest a lesser risk for AUD following VSG, although no preclinical studies have been done to confirm that. Therefore, the present study sought to determine the effects of VSG on ethanol intake and preferences in rodent models using protocols similar to those previously used in animal studies for RYGB. Male Sprague Dawley rats and male C57B6 mice were made obese on a high fat diet (60%kcal from fat) and received VSG or no surgery (controls). All animals then were given access to increasing concentrations of ethanol (2%, 4%, 6%, and 8%), presented for few days each. Compared to controls, VSG rats consumed significantly less of 2, 6 and 8% ethanol and showed significantly reduced preferences to 6 and 8% ethanol over water. VSG mice also displayed reduced intake and preference for 6 and 8% ethanol solutions. After a two-week period of forced abstinence, 8% ethanol was reintroduced and the VSG rats and mice continued to exhibit reduced consumption and less preference for ethanol. Regarding the underlying mechanism, we hypothesized that the removal of the ghrelin producing part of the stomach in the VSG surgery is a possible contributor to the observed reduced ethanol preference. To test for functional changes at the ghrelin receptors, the VSG and control rats were given IP injections of acyl-ghrelin (2.5nmol and 5nmol) prior to ethanol access. Neither concentration of ghrelin resulted in a significant increase in 8% ethanol consumption of VSG or control subjects. Next, the rats were given IP injections of the ghrelin receptor antagonist, JMV (2.5mg/kg body weight). This dose induced a significant reduction in 8% ethanol consumption in the VSG group, but no effect on ethanol intake in the controls. While ghrelin injection was uninformative, increased sensitivity to subthreshold doses of the ghrelin receptor antagonist may indicate reduced ghrelin signaling following VSG. Overall, these findings suggest that bariatric patients with increased susceptibility to AUD may benefit from receiving VSG instead of RYGB surgery, and that changes in ghrelin signaling, at least in part, may play a role in the differential AUD risks between the two most commonly performed bariatric surgical procedures.

Abstract
BACKGROUND Morbidly obese patients show an increased risk of postoperative hypoxemia and pulmonary complications when compared with normal weight subjects. The purpose of this study was to determine the effects of preoperative inspiratory muscular training (IMT) on postoperative arterial oxygenation in morbidly obese patients submitted to laparoscopic bariatric surgery. METHODS Forty-four morbidly obese patients were randomly assigned to receive either preoperative usual care (control group, n = 21) or preoperative IMT (trained group, n = 23) for a month prior to the date of surgery. Data on oxygenation (PaO2/FiO2 ratio) were obtained at 1 h and at 12 h after surgery (PACU 1 h and PACU 12 h, respectively). Data on maximum static inspiratory pressure (MIP) were obtained before and after the training period, and at postanesthesia care unit (PACU) 12-h time point. RESULTS PaO2/FiO2 was significantly higher in the trained group than in the control group, both at PACU 1 h (305.2 ± 77.6 vs. 248.8 ± 53.8, P = 0.008) and at PACU 12 h (333.5 ± 59.6 vs. 289.7 ± 79.6, P = 0.044). As a consequence, the percentage of patients with relative hypoxemia (PaO2/FiO2 lower than 300 mmHg) at the time of PACU discharge was higher in the control group (57 vs. 17 %, P: 0.006). MIP was significantly higher in the trained group compared with the control group at the preoperative time point (89.87 ± 19.00 vs. 77.00 ± 21.20 cm H2O, P = 0.04). CONCLUSIONS Preoperative IMT improved postoperative oxygenation and increased inspiratory muscular strength in morbidly obese patients submitted to laparoscopic bariatric surgery.

Abstract
OBJECTIVES To calculate the public health impact and economic benefit of using ancillary health care professionals for routine postoperative care. BACKGROUND The need for specialty surgical care far exceeds its supply, particularly in weight loss surgery. Bariatric surgery is cost-effective and the only effective long-term weight loss strategy for morbidly obese patients. Without clinically appropriate task shifting, surgeons, hospitals, and untreated patients incur a high opportunity cost. METHODS Visit schedules, time per visit, and revenues were obtained from bariatric centers of excellence. Case-specific surgeon fees were derived from published Current Procedural Terminology data. The novel Microsoft Excel model was allowed to run until a steady state was evident (status quo). This model was compared with one in which the surgeon participates in follow-up visits beyond 3 months only if there is a complication (task shifting). Changes in operative capacity and national quality-adjusted life years (QALYs) were calculated. RESULTS In the status quo model, per capita surgical volume capacity equilibrates at 7 surgical procedures per week, with 27% of the surgeon's time dedicated to routine long-term follow-up visits. Task shifting increases operative capacity by 38%, resulting in 143,000 to 882,000 QALYs gained annually. Per surgeon, task shifting achieves an annual increase of 95 to 588 QALYs, $5 million in facility revenue, 48 cases of cure of obstructive sleep apnea, 44 cases of remission of type 2 diabetes mellitus, and 35 cases of cure of hypertension. CONCLUSIONS Optimal resource allocation through task shifting is economically appealing and can achieve dramatic public health benefit by increasing access to specialty surgery.

Abstract
Bariatric surgery is increasingly recognized as a highly effective treatment for individuals who are severely obese. Amount of weight loss and resolution of comorbidities surpass those of nonsurgical approaches; however, suboptimal weight loss and weight regain are not uncommon. These outcomes, though not fully understood, are likely at least partially explained by failure to make long-term behavioral and/or cognitive changes. We are unaware of any established clinical tools to guide providers in assessing postoperative behaviors and identifying those who may require specialized treatment. The goal of this paper is to introduce a brief screening tool, The WATCH, to help clinicians assess and identify patients who may be at risk for poor or untoward outcomes post bariatric surgery. We first review the literature on postoperative outcomes, including weight loss, resolution of comorbidities, suboptimal outcomes, and development of problematic eating behaviors. We then provide an easily-recalled, five-item tool that assesses outcomes, and discuss patient responses that may necessitate further intervention or referral.

Abstract
Roux-en-Y gastric bypass (RYGB) is one of the most successful treatments for severe obesity and associated comorbidities. One potential adverse outcome, however, is increased risk for alcohol use. As such, we tested whether RYGB alters motivation to self-administer alcohol in outbred dietary obese rats, and investigated the involvement of the ghrelin system as a potential underlying mechanism. High fat (60%kcal from fat) diet-induced obese, non-diabetic male Sprague Dawley rats underwent RYGB (n = 9) or sham operation (Sham, n = 9) and were tested 4 months after surgery on a progressive ratio-10 (PR10) schedule of reinforcement operant task for 2, 4, and 8% ethanol. In addition, the effects of the ghrelin-1a-receptor antagonist D-[Lys3]-GHRP-6 (50, 100 nmol/kg, IP) were tested on PR10 responding for 4% ethanol. Compared to Sham, RYGB rats made significantly more active spout responses to earn reward, more consummatory licks on the ethanol spout, and achieved higher breakpoints. Pretreatment with a single peripheral injection of D-[Lys3]-GHRP-6 at either dose was ineffective in altering appetitive or consummatory responses to 4% ethanol in the Sham group. In contrast, RYGB rats demonstrated reduced operant performance to earn alcohol reward on the test day and reduced consummatory responses for two subsequent days following the drug. Sensitivity to threshold doses of D-[LYS3]-GHRP-6 suggests that an augmented ghrelin system may contribute to increased alcohol reward in RYGB. Further research is warranted to confirm applicability of these findings to humans and to explore ghrelin-receptor targets for treatment of alcohol-related disorders in RYGB patients.

Abstract
Enhanced recovery after surgery (ERAS) programs have been shown to minimise morbidity in other types of surgery, but comparatively less data exist investigating ERAS in bariatric surgery. This article reviews the existing literature to identify interventions which may be included in an ERAS program for bariatric surgery. A narrative literature review was conducted. Search terms included 'bariatric surgery', 'weight loss surgery', 'gastric bypass', 'ERAS', 'enhanced recovery', 'enhanced recovery after surgery', 'fast-track surgery', 'perioperative care', 'postoperative care', 'intraoperative care' and 'preoperative care'. Interventions recovered by the database search, as well as interventions garnered from clinical experience in ERAS, were used as individual search terms. A large volume of evidence exists detailing the role of multiple interventions in perioperative care. However, efficacy and safety for a proportion of these interventions for ERAS in bariatric surgery remain unclear. This review concludes that there is potential to implement ERAS programs in bariatric surgery.
