“…The literature has reported an average of 1.23 μmol/L within 30 days after surgery and 1.54 μmol/L 18 within months. In other words, there is a decline within 30 days after DGYR, followed by an increase within 18 months of follow-up, reaching a value close to that recorded before surgery (8,9,15,16,19,20,25,29) .…”

“…The average serum level of vitamin A in the sample was 1.8±0.5 μmol/L, i.e, within the normal range. The literature has reported na average level of vitamin A of 1.66 μmol/L before bariatric surgery, 1.25 μmol/L after 30 days of intervention, and 1.53 μmol/L after 18 months (1,8,9,15,16,19,25) .…”

-Background -Bariatric surgery is the most effective treatment for severe obesity, but the surgery increases the risk of developing nutritional deficiencies, such as vitamin A deficiency. In human metabolism, vitamin A plays a role in vision. Objective -To evaluate serum vitamin A, visual function and ocular surface of patients undergoing bariatric surgery. Methods -A cross-sectional and analytical study was conduced with 28 patients undergoing bariatric surgery for at least 6 months. Ophthalmologic evaluation was done through color vision test, contrast sensitivity test, ocular surface tests and confocal microscopy, as well as vitamin A serum measurement. Results -Vertical sleeve gastrectomy was performed in seven (25.0%) patients and Roux-en-Y gastric by-pass in 21 (75.0%). Mean serum vitamin A level was 1.7±0.5 µmoL/L. Most patients (60.7%) had symptoms of dry eye. Five (17.9%) patients had contrast sensitivity impairment and 18 (64.3%) color vision changes. In the group of patients undergoing Roux-en-Y gastric by-pass, mean vitamin A levels were 1.8±0.6 µmoL/L, whereas they were 1.7±0.5 µmoL/L in patients submitted to the restrictive technique vertical sleeve gastrectomy. The analysis of the influence of serum levels of vitamin A in the visual function and ocular surface was performed by Pearson correlation test and there was no significant correlation between any of the variables and vitamin A. Conclusion -There was no influence of the bariatric surgery technique used on serum vitamin A levels, on the visual function or on the ocular surface. Moreover, there was no correlation between serum levels of vitamin A and the visual function or the ocular surface changes. HEADINGS -Bariatric surgery. Vitamin A deficiency. Night blindness.

“…6 While BS has proven to be an effective procedure for a large proportion of those who are treated, there is a subset of patients (around 20%) who regain weight in the period from 18 months to 2 years after the operation. [7][8][9] Maintenance of weight loss is related to behavioral changes and the ability to implement lifestyle changes, to engagement in physical activities, changing dietary habits, and to development of strategies for coping and for emotional control unrelated to food. 10 In addition to variables related to surgery, psychological and emotional factors play an important role in maintenance of long-term results.…”

Trends Psychiatry Psychother. 2017;39(2):124-134. http://dx.doi.org/10.1590/2237-6089-2016 Abstract Introduction: Numerous studies have focused on psychological assessment of bariatric surgery candidates, aiming to identify which psychological variables, including personality characteristics, are related to successful surgical prognosis. Objective: To analyze, by means of a systematic literature review, longitudinal studies that investigated personality traits and disorders as possible predictors of outcomes in bariatric surgery. Method: PsycInfo, PubMed, and Scopus databases were searched for studies published between 2005 and 2015, using the keywords "bariatric" AND "personality." Quantitative longitudinal studies in English, Portuguese, or Spanish were selected for review if they assessed personality as an outcome predictor of BS in people aged 18 years or older. Results: Sixteen articles were analyzed. The results of this review suggest that externalizing dysfunctions might be associated with less weight reduction, while internalizing dysfunctions appear to be associated with somatic concerns and psychological distress. The persistence dimension (of temperament in Cloninger's model) was positively associated with greater weight loss, while neuroticism (Five Factor Model) and the occurrence of personality disorders were not predictive of weight loss. Furthermore, the results indicate a tendency towards a reduction in personality disorders and neuroticism scores, and an increase in extroversion scores, after BS. Conclusions: Assessment of personality characteristics, whether to identify their predictive power or to detect changes during the BS process, is important since it can provide grounds for estimating surgical prognosis and for development of interventions targeting this population.

“…One explanation for inferior outcomes in the bariatric patient population undergoing TKA is the presence of concomitant malnutrition in this patient population [11]. Many remain in a catabolic state for 2 years following bariatric surgical procedures [4].…”
