Osteoporosis affects a substantial proportion of patients with chronic liver disease. Pathologic fracture in osteoporosis significantly affects quality of life and life expectancy. By some estimates, 40% of patients with chronic liver disease may experience osteoporotic fracture. In this study we review the pathogenesis, diagnosis and treatment of specific liver disease entities and their relation to osteoporosis.
Bariatric surgery is considered one of the most effective methods of achieving long-term weight loss when all other medical treatments have failed. The number of bariatric procedures increases each year. Nevertheless, bariatric procedures are associated with a number of complications that require careful multidisciplinary management. Nutrition supervision is of substantial value, as malnutrition, vitamin, and micro- and macronutrient deficiencies may lead to deleterious consequences. In this review, we provide essential information on nutrition management, both before and after bariatric surgical procedures.
(vitamin D), and total calcium and phosphorus were assessed before and after a 3-month weight reduction therapy. Results: In obese subjects, serum concentrations of OPG, 25-(OH)-D 3 , osteocalcin, total calcium, and phosphorus were significantly lower, and serum concentration of parathormone was significantly higher, before weight reduction therapy in comparison with normal-weight controls. After weight reduction, a significantly higher serum concentration of 25-(OH)-D 3 and CTX and significantly lower concentration of OPG were found. Discussion: Serum concentration of OPG was significantly lower in obese patients in comparison with normal-weight controls. Weight reduction therapy resulted in further decrease in OPG serum concentrations. Therefore, OPG cannot be treated as a protective factor from bone loss in obese patients.
BackgroundAccording to recent studies, brain-derived neurotrophic factor (BDNF) probably plays a role in development of cerebral ischemia and can be significant for the prognosis of improved mobility after stroke. The aim of this prospective study was to evaluate the blood concentration of BDNF during the 1st day of first-ever ischemic stroke and find a potential association between BDNF concentration and the neurological status in the acute period, as well as between BDNF and the functional status in the sub-acute phase of stroke.Material/MethodsThe prospective study involved 87 patients aged 39–99 years (42 women, 45 men) with first-in-life complete ischemic stroke.All study subjects underwent analysis as follows: BDNF blood concentration and neurological status according to NIHSS on the 1st day of stroke, comorbidities, etiological type of ischemic stroke by ASCOD, and functional status on the 14th and 90th day after the onset according to mRankin scale.ResultsMean concentration of BDNF in the study group was 9.96 ng/mL±5.21, median 10.39 ng/mL. Patients aged ≤65 years (25 individuals) had a significantly higher mean concentration of BDNF (11.94 ng/mL±4.46; median 12.34 ng/mL) than the older subjects (62 individuals) with a mean concentration of 9.17 ng/mL±5.32 (median 8.66 ng/mL).The mean score by mRankin scale on the 90th day was significantly higher among patients with lower concentrations of BDNF on the 1st day of stroke, which reflects their poorer functional status.The functional status on the 90th day was significantly worse (3–6 points by Rankin scale) in patients who had BDNF below the mean value in the acute phase of stroke.The independent factors for poor functional status of patients on the 90th day after stroke were a score >4 points by NIHSS (RR 1.14; 95% CI: 1.00–1.31; p=0.027) and the concentration of BDNF below the mean value (assessed on the 1st day of stroke) (RR 14.49; CI 4.60–45.45; p=0.000).ConclusionsThe neurological status and concentration of BDNF on the 1st day of ischemic stroke are independent prognostic factors in medium-term observation.Reduction in the concentration of BDNF in the acute phase of stroke is a factor for poor prognosis in terms of the functional status of patients on the 90th day after onset.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
