Abstract
BACKGROUND Reference ranges for bone turnover markers (BTMs) are still lacking in the healthy Chinese population. AIM To establish reference intervals for BTMs and to investigate the correlations between BTMs and BMD in Chinese older adults. SUBJECTS AND METHODS A community-based cross-sectional study was conducted among 2,511 Chinese subjects aged over 50 yrs residing in Zhenjiang, Southeast China. Reference intervals for BTMs (i.e., procollagen type I N-terminal propeptide, P1NP; β cross-linked C-terminal telopeptide of type I collagen, β-CTX) were calculated as the central 95% range of all measurements in Chinese older adults. RESULTS The reference intervals of P1NP, β-CTX and P1NP/β-CTX were 15.8-119.9 ng/mL, 0.041-0.675 ng/mL and 49.9-1261.5 for females and 13.6-111.4 ng/mL, 0.038-0.627 ng/mL and 41.0-1269.1 for males, respectively. In the multiple linear regression analysis, only β-CTX was negatively associated with BMD after adjusting for age and body mass index (BMI) in both sex-stratified groups (all P < 0.05). CONCLUSION This study established age- and sex-specific reference intervals for BTMs in a large sample of healthy Chinese participants ≥ 50 and < 80 years of age and explored the correlations between BTMs and BMD, which provides an effective reference for the assessment of bone turnover in the clinical practice of osteoporosis.

Abstract
AIMS The aim of the present study was to evaluate umbilical cord N-terminal procollagen of type l collagen (P1NP) and beta C-terminal telopeptide (βCTX) levels in term pregnancies with vitamin D deficiency. MATERIALS AND METHODS Ninety-two pregnant women between 19 and 35-years-old who delivered at term gestational age were included in the study and divided into deficient (n = 32), insufficient (n = 30), and normal (control) vitamin D levels (n = 30). RESULTS Maternal demographic characteristics and biochemical parameters were similar among groups. The mean umbilical cord P1NP level was 221.4 (211.7-231.0, 95%CI) pg/mL in the vitamin D deficiency group, 282.5 (271.2-293.8, 95%CI) pg/mL in the vitamin D insufficiency group, and 280.9 (270.9-290.8, 95%CI) pg/mL in the control group and significantly lower in vitamin D deficiency group than others (p < .001). Umbilical cord P1NP level was similar in the vitamin D insufficiency group and control group (p = .971). The mean umbilical cord βCTX level was 5530, 9 (5511.5-5550.3, 95%CI) pg/mL in the vitamin D deficiency group, 5516.3 (5498.4-5534.2, 95%CI) pg/mL in the vitamin D insufficiency group, and 5510 (5491.4-5528.5, 95%CI) pg/mL in the control group, which was statistically similar among the groups (p = .251). CONCLUSION Our results indicated that vitamin D deficiency during pregnancy affects fetal bone osteoblast activity.

Are We Ready for Bariatric Surgery in a Liver Transplant Program? A Meta-Analysis. Obes Surg 2020; 31:1214-1222. [PMID: 33225408 DOI: 10.1007/s11695-020-05118-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2020] [Revised: 10/30/2020] [Accepted: 11/10/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND Obesity-related non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) are two main causes of end-stage liver disease requiring a liver transplantation. Studies exploring bariatric surgery in the liver transplantation setting have increased in recent years; however, a systematic analysis of the topic is lacking to date. This meta-analysis was conducted to explore the perioperative and long-term outcomes of bariatric surgery in obese patients undergoing liver transplantation. METHODS Electronic databases were systematically searched for studies reporting bariatric surgery in patients undergoing liver transplantation. The primary outcomes were postoperative complications and mortality. We also extracted data about excess weight loss, body mass index, and improvement of comorbidities after bariatric surgery. RESULTS A total of 96 patients from 8 articles were included. Bariatric surgery-related morbidity and mortality rates were 37% (95% CI 0.27-0.47) and 0.6% (95% CI 0.02-0.13), respectively. Body mass index at 24 months was 31.02 (95% CI 25.96-36.09) with a percentage excess weight loss at 12 and 24 months of 44.08 (95% CI 27.90-60.26) and 49.2 (95% CI 31.89-66.66), respectively. After bariatric surgery, rates of improvement of arterial hypertension and diabetes mellitus were 61% (95% CI 0.45-0.75) and 45% (95% CI 0.25-0.66), respectively. In most patients, bariatric surgery was performed after liver transplant and the most frequent technique was sleeve gastrectomy. CONCLUSIONS Bariatric surgery can be performed safely in the setting of liver transplantation resulting in improvement of obesity-related comorbidities. The optimal timing and technique require further studies.
