Quality of Life after Bariatric Surgery-A Systematic Review.

BACKGROUND: Most studies analyzing the health-related quality of life (HRQOL) after bariatric treatment ceased at five years post-surgery or even earlier, and it is unclear whether the HRQOL benefit persists for a longer time. This paper reviews sparse evidence regarding HRQOL in patients who underwent bariatric surgery at least nine years prior. MATERIALS AND METHODS: A of PubMed, Scopus and Google Scholar between 2007-2021 was carried out for the studies investigating HRQOL as an outcome measure in patients after bariatric surgery of any type and having at least a 9-year follow-up. Inconsistent reporting of weight loss or postgraduate study results unrelated to QoL were not included in the study. The study used the PICO procedure. RESULTS: The review of 18 identified publications demonstrated that bariatric treatment seems to provide a persistent benefit in terms of HRQOL, especially its physical component score. Due to psychological predispositions, some patients appear to be less likely to benefit from bariatric treatment, whether in terms of HRQOL or bodyweight reduction. Inconsistent and imprecise studies may limit the evidence included in a review. CONCLUSIONS: The early identification of such patients and providing them with holistic care, including psychological intervention, would likely further improve the outcomes of bariatric treatment.

Plasma carnitine concentrations after chronic alcohol intoxication.

BACKGROUND: Carnitine transports fatty acids from the cytoplasm to the mitochondrial matrix, where the fatty acids are oxidized. Chronic alcohol consumption reduces the concentration of carnitine and interferes with oxidative processes occurring in the cell. AIM: The assessment of carnitine concentrations in plasma of chronically intoxicated alcohol dependent persons in a 49-day abstinence period. MATERIAL/METHODS: The study included 31 patients (5 women and 27 men) aged from 26 to 60 years (44.6 ± 8.9) and 32 healthy subjects (15 women and 17 men) aged 22-60 years (39.8 ± 9.4). The patients' alcohol dependence ranged from 2 to 30 years (13.6 ± 7.5). Examined subjects consumed 75-700 g of ethanol/day (226.9 ± 151.5). Plasma concentrations of free and total carnitine were measured three times: at the first (T0), 30th (T30) and 49th (T49) day of hospital detoxification. Free (FC) and total (TC) carnitine were determined by the spectrophotometric method. Plasma acylcarnitine (AC) concentration was calculated from the difference between TC and FC; then the AC/FC ratio was calculated. To determine statistically significant differences for related variables, Student's t-test was used. RESULTS: At T0, alcoholics had significantly lower concentration of FC and TC (p < 0.05) in plasma, as compared to the control group. In comparison to controls, at T30, plasma TC and FC (p < 0.01) as well as AC (p < 0.001) were reduced. The lowest concentration of TC, FC and AC (p < 0.001)was found at T49. The ratio of AC/FC at T0 had a tendency to be higher in alcoholics than in the control group (p = 0.05), whereas at T49 it was significantly lower in alcoholics as compared to the control subjects (p < 0.05). CONCLUSIONS: Chronic alcohol intoxication causes a plasma deficiency of carnitine. Forty-nine days of abstinence showed a significant decrease in the concentration of TC, FC and AC. Further research is necessary to clarify whether a low level of plasma carnitine after chronic alcohol intoxication is caused by the uptake of blood carnitine by tissues such as liver or muscles. In alcoholics the supplementation of carnitine is recommended in the case of a low level of plasma carnitine.
