Alcohol sensitivity in women after undergoing bariatric surgery: a cross-sectional study.

ABSTRACT:

Background

Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), the most common bariatric surgeries performed worldwide, increase the risk to develop an alcohol use disorder. This might be due, in part, to surgery-related changes in alcohol pharmacokinetics. Another risk factor, unexplored within this population, is having a reduced subjective response to alcohol's sedative effects.

Objectives

To assess whether the alcohol sensitivity questionnaire (ASQ), a simple self-report measure, could pinpoint reduced alcohol sensitivity in the bariatric population.

Setting

University medical centers in Missouri and Illinois.

Methods

Women who had RYGB (n = 16), SG (n = 28), or laparoscopic adjustable gastric banding surgery (n = 11) within the last 5 years completed the ASQ for both pre- and postsurgical timeframes, and 45 of them participated in oral alcohol challenge testing postsurgery. Blood alcohol concentration (BAC) and subjective stimulation and sedation were measured before and for 3.5 hours after drinking.

Results

In line with faster and higher peak BACs after RYGB and SG than laparoscopic adjustable gastric banding surgery (P < .001), postsurgery ASQ scores were more reduced from presurgery scores after RYGB/SG than after laparoscopic adjustable gastric banding surgery (-2.3 ± .3 versus -1.2 ± .2; P < .05). However, despite the dramatic changes in BAC observed when ingesting alcohol after RYGB/SG surgeries, which resulted in peak BAC that were approximately 50% above the legal driving limit, a third of these women felt almost no alcohol-related sedative effects.

Conclusions

Although RYGB/SG dramatically increased sensitivity to alcohol in all participants, meaningful interindividual differences remained. The ASQ might help identify patients at increased risk to develop an alcohol use disorder after surgery.

Project description:BACKGROUND:In recent years, obesity has become one of the most important public health problems in the world, with a growing prevalence in both developed and developing countries. Recent studies show that sleep disturbances, especially obstructive sleep apnoea (OSA) may be a manifestation of metabolic syndrome (MetS). Although the association of OSA with the MetS is largely attributed to obesity, the exact pathophysiological mechanisms and their individual characteristics still need to be identified. This study investigated the prevalence and severity of syndrome Z in obese women with MetS on waiting list for bariatric surgery. METHODS:In this double-center cross-sectional study, female patients aged ?18 years, stage III severe obesity with MetS, on waiting list for bariatric surgery were recruited. The diagnosis for MetS was made according to the criteria of the national cholesterol education program, adult treatment panel III. Clinical, anthropometric, demographic, biochemistry, and sleep measurements were collected. Correlations between continuous variables with sleep parameters were performed using the Pearson correlation test or Spearman correlation test. RESULTS:The mean age of 83 patients was 44.8 ± 11.2 years and mean BMI was 42.6 ± 8.1 kg/m2. There was a significant correlation between OSA and metabolic score (r = 0.336; P = 0.002), neck circumference (r = 0.218; P = 0.048), basal systolic blood pressure (r = 0.280; P = 0.01), total cholesterol (r = 0.277; P = 0.011) and abdomen circumference (r = 0.284; P = 0.009). The mean values of excessive daytime sleepiness were 10.5 ± 7 demonstrating a value considered normal for its presence. However, a high risk for OSA was observed in practically the entire population. It was observed that the prevalence of Syndrome Z (75.9%) increased significantly according to apnoea hypopnoea index (AHI) (P for trend <0.0000). A prevalence of 27.71% for mild OSA, 20.48% for moderate OSA, and 27.71% for severe OSA was observed. An association of AHI severity with all components of MetS was also observed. CONCLUSIONS:We can conclude that syndrome Z presents a high prevalence in a female population with MetS and a considerable severity according to the presence of OSA. Therefore, patients with MetS should be investigated for the presence of sleep disorders.

Project description:Severe obesity in childhood is a major health problem with few effective treatments. Weight-loss surgery (WLS) is being used to treat severely obese adolescents, although with very limited data regarding surgical safety for currently used, minimally invasive procedures.To assess the preoperative clinical characteristics and perioperative safety outcomes of severely obese adolescents undergoing WLS.This prospective, multisite observational study enrolled patients from February 28, 2007, through December 30, 2011. Consecutive patients aged 19 years or younger who were approved to undergo WLS (n?=?277) were offered enrollment into the study at 5 academic referral centers in the United States; 13 declined participation and 22 did not undergo surgery after enrollment, thus the final analysis cohort consisted of 242 individuals. There were no withdrawals.This analysis examined preoperative anthropometrics, comorbid conditions, and major and minor complications occurring within 30 days of operation. All data were collected in a standardized fashion. Reoperations and hospital readmissions were adjudicated by independent reviewers to assess relatedness to the WLS procedure.The mean (SD) age of participants was 17.1 (1.6) years and the median body mass index (calculated as weight in kilograms divided by height in meters squared) was 50.5. Fifty-one percent demonstrated 4 or more major comorbid conditions. Laparoscopic Roux-en-Y gastric bypass, vertical sleeve gastrectomy, and adjustable gastric banding were performed in 66%, 28%, and 6% of patients, respectively. There were no deaths during the initial hospitalization or within 30 days of operation; major complications (eg, reoperation) were seen in 19 patients (8%). Minor complications (eg, readmission for dehydration) were noted in 36 patients (15%). All reoperations and 85% of readmissions were related to WLS.In this series, adolescents with severe obesity presented with abundant comorbid conditions. We observed a favorable short-term complication profile, supporting the early postoperative safety of WLS in select adolescents. Further longitudinal study of this cohort will permit accurate assessment of long-term outcomes for adolescents undergoing bariatric surgery.clinicaltrials.gov Identifier: NCT00474318.

Project description:Background:For patients undergoing breast cancer surgery, the pre- and post-operative periods can be characterised by feelings of fear, anxiety, and uncertainty. Telehealth offers an opportunity to provide perioperative support to surgical patients and overcome some of the barriers to accessing care. Aims:In order to inform the development of a telehealth support model for women undergoing breast cancer surgery, this feasibility study explored: (a) access and preferences for telehealth; and (b) the proportion of participants who reported problems with unmet information and preparation needs related to surgery, post-operative pain, anxiety, and quality of life. Methods:Women aged 18-85 years attending for a follow-up appointment within 2 months of undergoing surgery for breast cancer were asked to complete a baseline (T1) and 1-month follow-up (T2) survey. Surveys assessed telehealth access and preferences, preparatory information receipt and preparedness for surgery, and anxiety, pain, and quality of life. Results:Fifty-three T1 (45% consent rate) and 50 T2 surveys were returned. One fifth of the sample (20%) travelled 50 km or more to access surgery. Most participants had access to a device suitable for telehealth (75%); however, only 15% indicated that they would have accepted a teleconsultation with their surgeon post-operatively if this had been offered. The most frequently reported unmet preparatory information needs were information about: how long it would take to recover from the surgery; how other patients had experienced similar surgery; and practical needs such as parking or transport. Approximately one third of the sample reported potentially clinically significant symptoms of anxiety, and less than one in ten women reported moderate levels of pain. Conclusions:While the majority of women had access to a suitable device and internet connection for telehealth, less than one fifth would have accepted a home-based video-link teleconsultation with their surgeon post-operatively. A small proportion of the sample would have liked more information about aspects of surgery including about managing side effects and anxiety. The key findings in terms of teleconsultation preferences and information and preparation needs from this study will be incorporated into the telehealth support model being developed.

Project description:BackgroundIn obese patients, periodontitis might be associated with deprived systemic health. Edmonton obesity staging system (EOSS) is a new tool for classification of obesity that considers the metabolic, physical, and psychological health. The cross-sectional study aimed to evaluate the periodontal status of morbidly obese patients eligible for bariatric surgery and the association between periodontitis, obesity-related comorbidities, and EOSS.MethodsMorbidly obese patients eligible for bariatric surgery underwent detailed periodontal examination and were divided into the periodontitis group (PG) and the non-periodontitis group (NPG). The medical and demographic data were obtained from medical files, while behavioural data were obtained by the interview. Descriptive statistics and simple statistical tests were used to summarise the characteristics of the sample and the differences between PG and NPG. The logistic regression models were used to calculate the association (odds ratio (OR)) between periodontitis and obesity-related diseases and EOSS.ResultsThe study included 79 patients, with an average BMI of 44.6 kg/m2 (SD = 7.2). The prevalence of periodontitis was 65% (CI 95% 53%-75%). PG patients (n = 51) were older, more often smokers and were more often hypertensive than NPG patients (n = 28) (p < 0.05). Hypertension was positively associated with periodontitis with adjusted OR 3.98 (95% CI 1.23-12.8; p = 0.021)) and age with adjusted OR 1.06, (95% CI 1.01-1.13; p = 0.038)), while other tested conditions (diabetes, dyslipidaemia, and smoking habits) did not show significant association with periodontitis. Periodontitis did not correlate with EOSS or other obesity-related comorbidities (p > 0.05).ConclusionThe morbidly obese patients eligible for bariatric surgery show a high prevalence of periodontitis and, therefore, are advised to be examined by a dentist before undergoing surgery. They have higher odds of hypertension but not of other obesity-related diseases or higher stages of EOSS. The medical personnel should raise awareness among obese patients on the potential association of poor periodontal health with hypertension.Trial registrationNCT04653714.
