Comprehensive geriatric assessment of older patients with renal disease: a cross-sectional survey.

Multidimensional health function impairments are common in older patients with chronic kidney disease (CKD). The purpose of this study was to explore whether the risk or severity of geriatric syndrome increased with a decline in renal function. This survey was conducted for CKD patients aged ≥ 60 years and hospitalized at West China Hospital of Sichuan University (Center of Gerontology and Geriatrics, Nephrology, and Endocrinology) and Chengdu Kangfu Kidney Disease Hospital from September 01, 2013 to June 30, 2014. Patients underwent multidimensional individualized assessments by trained doctors. Logistic regression analysis found that the risk of assisted walking (P = 0.001) and urinary incontinence (P = 0.039) increased with a decline in renal function. Regression analysis revealed that the scores of activities of daily living (P = 0.024), nutritional status (P = 0.000), total social support (P = 0.014), and objective support (P = 0.000) decreased with a decline in renal function.

Prevalence and associated factors of hyperuricemia among Chinese patients with diabetes: a cross-sectional study.

Background: As a part of metabolic syndrome, hyperuricemia has a higher incidence in patients with diabetes than in the general population owing to various underlying factors. Objectives: The objective of the present study was to investigate the prevalence of hyperuricemia among patients with diabetes and identify associated factors. Design: A cross-sectional study. Methods: Herein, we included patients with diabetes managed at nine healthcare centers in Chenghua District, Chengdu, from February 2021 to November 2021. Clinical data, lifestyle habits, and laboratory data were collected to determine the prevalence and factors associated with hyperuricemia. Results: In total, we included 1577 patients with diabetes (males, 50.35%; females, 49.65%). The median serum uric acid level was 337.9 µmol/L, and the prevalence of hyperuricemia in patients with diabetes was 21.24%. The prevalence of hyperuricemia in male patients was significantly higher than in females (29.35% in males versus 13.03% in females, p < 0.001). Male patients with obesity (p = 0.006) or triglyceride (TG) ⩾ 1.7 mmol/L (p < 0.001) had a high risk of developing hyperuricemia, and hyperuricemia was negatively associated with estimated glomerular filtration rate (eGFR) ⩾ 60 mL/min/1.73 m2 (p < 0.001), glycosylated hemoglobin (HbA1c) ⩾ 7% (p < 0.001), fenofibrate (p = 0.010), and sodium-glucose cotransporter 2 (SGLT-2) inhibitors (p = 0.035). Considering females, overweight (p = 0.004), alanine transaminase (ALT) > 40 U/L (p < 0.001), and TG ⩾ 1.7 mmol/L (p = 0.015) showed a significant positive correlation with hyperuricemia, while eGFR ⩾ 60 mL/min/1.73 m2 (p < 0.001) was negatively associated with the risk of hyperuricemia. Conclusion: Hyperuricemia is highly prevalent in patients with diabetes, especially in males. In addition to traditionally associated factors, fenofibrate and SGLT-2 inhibitors were also associated with the risk of hyperuricemia. Registration: The study protocol was registered in the Chinese Clinical Trial Registry (http://www.chictr.org.cn/), and the registration number was ChiCTR 2100042742.

Association of vitamin D status with all-cause mortality and outcomes among Chinese individuals with diabetic foot ulcers.

AIMS/INTRODUCTION: The aim of this study was to examine the correlation between serum vitamin D concentrations and prognosis among Chinese individuals with diabetic foot ulcers (DFUs). MATERIALS AND METHODS: We retrospectively recruited 488 adults with DFUs in West China Hospital from 1 January 2012 to 31 December 2019. After telephone follow up, 275 patients were finally included. We compared serum vitamin D concentrations among DFUs patients with different prognostic status, and examined the association of vitamin D status with prognostic variables by Kaplan-Meier analysis. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals for all-cause mortality. RESULTS: The median concentration of serum vitamin D of patients with DFUs was 37.78 nmol/L (interquartile range 27.91-50.66 nmol/L), with 31.6% having vitamin D deficiency (<30 nmol/L) and 42.2% having insufficient vitamin D (<50 nmol/L). During a median follow-up period of 52 months, 65 patients died, with an all-cause mortality of 23.64%. Vitamin D deficiency was independently linked to increased all-cause mortality after multivariable adjustments (hazard ratio 0.565, 95% confidence interval 0.338-0.946, P = 0.030). There were no significant differences between vitamin D concentrations and other outcomes of DFUs. Patients who suffered amputations had a tendency of lower vitamin D concentrations (34.00 [interquartile range 26.90-41.81] vs 40.21 [interquartile range 29.60-53.96] nmol/L, P = 0.053). CONCLUSIONS: Vitamin D deficiency was significantly associated with increased all-cause mortality in Chinese individuals with DFUs. Vitamin D supplementation might be a potential therapy for DFUs to prevent premature death and improve outcomes.

[Characteristics of Inflammatory Markers in Diabetic Foot Patients and Their Relationship With Prognosis of Diabetic Foot Ulcers]. / ç³–å°¿ç— è¶³æ‚£è€ ç‚Žç—‡æ ‡å¿—ç‰©ç‰¹å¾åŠå ¶ä¸Žè¶³æºƒç–¡é¢„åŽå ³ç³».

Objective: To explore the characteristics of baseline inflammatory markers in diabetic foot patients and their relationship with the prognosis of diabetic foot ulcers. Methods: The clinical data of diabetic foot patients (n=495) admitted to West China Hospital, Sichuan University since 2016 were retrospectively collected through the hospital electronic medical record system to analyze the characteristics of inflammatory markers and their relationship with the prognosis of diabetic foot ulcers. Results: White blood cell count (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), procalcitonin (PCT), and interleukin-6 (IL-6) levels were significantly higher in patients defined as grade 4 on the Wagner Scale than those in patients defined as grade 0-3 on the Wagner Scale. Neutrophil percentage (NE%) was higher in Wagner grade-4 patients than those in Wagner grade-0 and grade-1 patients and higher in Wagner grade-3 patients than those in Wagner grade-0 patients. NE%, CRP, PCT, and IL-6 levels were positively correlated with the severity of diabetic foot, with the respective odds ratio (OR) at 95% confidence interval (CI) being 1.038 (1.019-1.056), 1.019 (1.012-1.026), 8.225 (2.015-33.576), and 1.017 (1.008-1.025). Using Wagner grade-0 patients as the reference, patients with higher WBC were more likely to progress to Wagner grade 2, 3, and 4, with the respective OR (95% CI) values being 1.260 (1.096-1.447), 1.188 (1.041-1.356), and 1.301 (1.137-1.490); patients with higher ESR were more likely to progress to Wagner grade 3 and 4, with the respective OR (95% CI) values being 1.030 (1.006-1.054) and 1.045 (1.019-1.071). Baseline ESR (P=0.008), CRP (P=0.039), and IL-6 (P=0.033) levels were lower in patients who had received antibiotics prior to their admission than those in patients who had not received antibiotics before admission. The levels of WBC, NE%, ESR, PCT, and IL-6 were lower in the full recovery group than those in the group of patients who did not respond to treatment. The higher the levels of NE% and IL-6, the worse the prognosis of diabetic foot ulcers became, with the respective OR (95% CI) values being 1.030 (1.010-1.051) and 1.008 (1.002-1.013). Conclusion: The severity of diabetic foot ulcers increased with the rise in baseline levels of inflammatory markers. Elevated baseline NE% and IL-6 levels suggest a poor prognosis. Our findings suggest that early assessment of diabetic foot infection and standardized antibiotic therapy should be implemented to improve the prognosis.

Effectiveness and safety of Danmu extract syrup for acute upper respiratory tract infection in children: A real-world, prospective cohort study.

AIM: To evaluate the effectiveness and safety of Danmu Extract Syrup for the treatment of acute upper respiratory tract infection (AURI) in children. METHODS: In this prospective cohort study, we enrolled children with AURI in the pediatric outpatient department and emergency department of West China Second Hospital. According to the treatment, they were divided into two groups: Danmu Extract Syrup Group (Danmu Group) and Xiaoer Chiqiao Granule Group (Chiqiao Group). The primary outcome was time to symptom remission, and the secondary outcomes were defervescence time, relief time, admission rate, and adherence. We used restricted mean survival time (RMST) to quantify the treatment effects and test noninferiority for primary outcome. Propensity score matching (PSM) was used to adjust confounding. Subgroup analysis and sensitivity analysis were used to verify the robustness of results. RESULTS: We enrolled 1036 children with AURI, including 516 in Danmu Group and 520 in Chiqiao Group. After PSM, no significant difference was observed in the baseline characteristics of the two groups. The primary results showed that the RMST difference was -3 h (95% CI: -15.1 to 9.1) and the upper limit of the 95% CI was less than the noninferiority margin of 11 h. There was no statistical difference in the secondary outcomes except for defervescence between the two groups. The results of safety analysis showed that the incidence of adverse events occurred is 4.1% in Danmu Group, which was lower than the incidence of Chiqiao Group (6.9%). CONCLUSION: This study indicated that Danmu extract syrup is noninferiority to Chiqiao Granule for AURI in children.

A new approach for investigating the relative contribution of basal glucose and postprandial glucose to HbA1C.

To develop an accurate method for evaluating the relative contributions of basal glucose (BG) and postprandial glucose (PPG) to glycated haemoglobin (HbA1c) in subjects with hyperglycaemia using a Continuous Glucose Monitoring System (CGMS®). The subjects were divided into the normal glucose tolerance (NGT), impaired glucose tolerance (IGT), newly-diagnosed type 2 diabetes (NDDM), and drug-treated type 2 diabetes (T2DM) groups. We evaluated the relative contributions of BG and PPG to HbA1c in patients with hyperglycaemia according to three different baseline values. Subjects (n = 490) were grouped as follows: 92 NGT, 36 IGT, 131 NDDM, and 231 T2DM. The relative contributions of PPG to HbA1c were calculated using baseline values of 6.1 mmol/L, 5.6 mmol/L, and the 24-h glucose curve of the NGT group. The relative contribution of PPG to HbA1c decreased progressively from the IGT group to the T2DM group. Compared with the 24-h glucose curve as the baseline, the relative contribution of PPG was overestimated in 9.04% and 1.76% of the subjects when 6.1 mmol/L and 5.6 mmol/L were used as baselines, respectively (P < 0.01), in T2DM patients. The 24-h glucose curve of NGT is more suitable for studying the relative contributions of BG and PPG to HbA1c and it is more precise, as it considers physiological fluctuations in NGT after meals. However, 5.6 mmol/L can be used when the 24-h glucose curve for NGT is unavailable; using 6.1 mmol/L as a baseline value may overestimate the contribution to the HbA1c. There is no unified standard for assessing the contributions of basal glucose (BG) and postprandial glucose (PPG) to HbA1c. The 24-h glucose curve of NGT is more suitable for studying the relative contributions of BG and PPG to HbA1c, as it considers physiological fluctuations in NGT after meals. However, 5.6 mmol/L can be used when the 24-h glucose curve for NGT is unavailable; using 6.1 mmol/L as a baseline value may overestimate the contribution to the HbA1c.

Effects of novel diabetic therapeutic footwear on preventing ulcer recurrence in patients with a history of diabetic foot ulceration: study protocol for an open-label, randomized, controlled trial.

BACKGROUND: Recurrence after the healing of a foot ulcer is very common among patients with diabetes mellitus. Novel diabetic therapeutic footwear consisted of merino wool, vibration chip, and orthopedic insoles is designed to influence multifaceted mechanisms of foot ulcer occurrence. The aim of this study is to examine the effect of the optimally designed therapeutic footwear on preventing ulcer recurrence in patients with a history of diabetic foot ulcers (DFU). METHODS/DESIGN: The trial is designed as a two arms, parallel-group, open-label randomized controlled intervention study. The Log-rank Test was used for calculating sample size based on the latest national multicenter survey data of DFU in China. Three hundred and twenty participants will be recruited from the Diabetic Foot Care Center, West China Hospital, Sichuan University. Adults with diabetic peripheral neuropathy, healed foot ulceration in the 3 months prior to randomization, and aged ≥18 years, will be recruited. Participants will be randomized to receive novel diabetic therapeutic footwear (n = 160) or their own footwear (n = 160). The primary outcome will be the incidence of ulcer recurrence. The secondary outcome will be measurements of barefoot dynamic plantar pressures, the influence of footwear adherence on ulcer recurrence, and the incidence of cardiovascular events. Assessment visits and data collection will be obtained at baseline, 1, 3, 6, 9, and 12 months. The intention-to-treat principle will be applied. A cox regression model will be used to calculate the hazard ratio for the incidence of ulcer recurrence. The change of barefoot dynamic plantar pressures will be assessed using repeated measures ANOVA. The study protocol has been approved by the Ethics Committee of The Biomedical Research Ethics Committee of West China Hospital, Sichuan University (Reference No. 2019(96)). DISCUSSION: This clinical trial will give information on the ability of novel diabetic footwear on preventing ulcer recurrence in patients with a history of diabetic foot ulceration. If the optimally designed therapeutic footwear does work well, the findings will contribute to the development of innovative treatment devices for preventing foot ulcer recurrence in high-risk patients.

Efficacy and Safety of Stem Cell Therapy for T1DM: An Updated Systematic Review and Meta-Analysis.

BACKGROUND: The long-term insulin therapy for type 1 diabetes mellitus (T1DM) fails to achieve optimal glycemic control and avoid adverse events simultaneously. Stem cells have unique immunomodulatory capacities and have been considered as a promising interventional strategy for T1DM. Stem cell therapy in T1DM has been tried in many studies. However, the results were controversial. We thus performed a meta-analysis to update the efficacy and safety of stem cell therapy in patients with T1DM. METHODS: We systematically searched the Medline, EMBASE, Cochrane Central Register of Controlled Trials, ClinicalTrials.gov, Web of Science, Wan Fang Data, China National Knowledge Infrastructure, VIP database, and the Chinese Biomedical Literature Database (SinoMed) for relevant studies published before March 19, 2019. The outcomes included parameters for glycemic control (i.e., glycosylated hemoglobin (HbA1c) levels and insulin dosages), ß cell function (i.e., fasting C-peptide levels and area-under-curve of C-peptide concentration (AUCC)), and relative risk of adverse events. Statistical analysis was conducted by using RevMan 5.3 and Stata 12.0. RESULTS: Five randomized controlled trials (RCTs) and eight nonrandomized concurrent control trials (NRCCTs) with a total of 396 individuals were finally included into the meta-analysis. Among RCTs, stem cell therapy could significantly reduce HbA1c levels (MD = -1.20, 95% CI -1.91 to -0.49, P = 0.0009) and increase fasting C-peptide levels (MD = 0.25, 95% CI 0.04 to 0.45, P = 0.02) and AUCC (SMD = 0.66, 95% CI 0.13 to 1.18, P = 0.01). Stem cell therapy could also reduce insulin dosages (SMD = -2.65, 95% CI -4.86 to -0.45, P = 0.02) at 6 months after treatment. NRCCTs also had consistent results. Furthermore, RCTs showed stem cell therapy did not increase relative risk of gastrointestinal symptom (RR = 0.69, 95% CI 0.14 to 3.28, P = 0.64) and infection (RR = 0.97, 95% CI 0.40 to 2.34, P = 0.95). However, NRCCTs showed stem cell therapy increased relative risk of gastrointestinal symptom (RR = 44.49, 95% CI 9.20 to 215.18, P < 0.00001). CONCLUSION: Stem cell therapy for T1DM may improve glycemic control and ß cell function without increasing the risk of serious adverse events. Stem cell therapy may also have a short-term (3-6 months) effect on reducing insulin dosages.

Evidence-based topical treatments (azelaic acid, salicylic acid, nicotinamide, sulfur, zinc, and fruit acid) for acne: an abridged version of a Cochrane systematic review.

OBJECTIVE: The effects of topical azelaic acid, salicylic acid, nicotinamide, sulfur, zinc, and fruit acid (alpha-hydroxy acid) for acne are unclear. We aimed to assess the effects of these topical treatments by collecting randomized controlled trials. METHODS: We searched The Cochrane Skin Group Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS up to May 2019. We also searched five trials registers. Two review authors independently extracted data and assessed risk of bias. Meta analyses were performed by using Review Manager 5 software. RESULTS: We included a total of 49 trials involving 3880 participants. In terms of treatment response (measured using participants' global self-assessment of acne improvement, PGA), azelaic acid was probably less effective than benzoyl peroxide (RR = 0.82, 95% CI 0.72-0.95). However, there was probably little or no difference in PGA when comparing azelaic acid to tretinoin (RR = 0.94, 95% CI 0.78-1.14). There may be little or no difference when comparing salicylic acid to tretinoin (RR = 1.00, 95% CI 0.92-1.09). There were no studies measured PGA when evaluating nicotinamide. With respect to alpha-hydroxy acid, there may be no difference in PGA when comparing glycolic acid to salicylic-mandelic acid (RR = 1.06, 95% CI 0.88-1.26). We were uncertain about the effects of sulfur and zinc. Adverse events associated with these topical treatments were always mild and transient. CONCLUSIONS: Moderate-quality evidence was available for azelaic acid and low- to very-low-quality evidence for other topical treatments. Risk of bias and imprecision limit our confidence in the evidence.

A Novel Index in Hepatocellular Carcinoma Patients After Curative Hepatectomy: Albumin to Gamma-Glutamyltransferase Ratio (AGR).

Aim: As high gamma-glutamyltransferase level or low albumin had negative impacts on the prognosis of hepatocellular carcinoma (HCC), the prognostic role of albumin to gamma-glutamyltransferase ratio (AGR) in HCC patients after hepatectomy remains unclear. Methods: Between January 2007 and December 2015, 1143 HCC patients after hepatectomy were reviewed from a prospectively maintained database in West China Hospital. All qualified patients (n = 959) were classified as training set (year 2007-2012, n = 480) and validation set (year 2012-2017, n = 479). A time-dependent receiver operating characteristic (ROC) curve analysis was performed to evaluate the performance. Result: AGR = 0.5 was identified as the best cut-off point to predict recurrence free survival (RFS) and overall survival (OS) in the training set. Low AGR was related to poor tumor characteristics and high systemic inflammation. Based on the multivariate analysis, high AGR was an independent predictor for better RFS and OS with an hazard ratio of 0.696 and 0.673. The high AGR group had better RFS and OS than the low AGR group in the training set as well as the validation set. The AGR-based score (AGR-PLR) could stratify HCC patients into three subgroups with different prognosis in the training and validation set. Patients with score 1 had a worse prognosis than those with AGR-PLR score 0, but better than those with AGR-PLR score 2. The predictive accuracy of the AGR-PLR score appeared superior to that of the AGR or PLR alone. Conclusions: we firstly reported that AGR ≤ 0.5 was an independently prognostic factor in HCC after hepatectomy. The AGR-PLR score could further improve the discriminatory ability of prognosis.

Effects of Nicorandil on All-Cause Mortality and Cardiac Events in CAD Patients Receiving PCI.

Current studies demonstrating the effects of nicorandil in the prognosis of coronary artery disease (CAD) patients who received percutaneous coronary intervention (PCI) are inconclusive due to the small sample size and small events rate.PubMed, OVID, CBM and CNKI databases were searched using a pre-specified search string to collect randomized controlled trials (RCTs) studying the effects of nicorandil on CAD patients receiving PCI. Data on all-cause mortality and cardiovascular events were collected. RevMan 5.3 software was used for meta-analysis. Subgroup analysis was conducted in patients receiving primary PCI (PPCI) and elective PCI (EPCI).A total of 18 RCTs were included in our final analysis. Nicorandil treatment significantly reduced total mortality in PPCI (Peto OR = 0.44, 95%CI 0.25-0.79, P = 0.006) and EPCI (Peto OR = 0.41, 95%CI 0.25-0.67, P = 0.0004), cardiovascular death in both PPCI (Peto OR = 0.41, 95%CI 0.20-0.84, P = 0.01) and EPCI (Peto OR = 0.40, 95%CI 0.20-0.80, P = 0.009), and heart failure in PPCI (RR = 0.36, 95%CI 0.22-0.59, P < 0.0001). When compared with placebo plus standard treatment or standard treatment alone, nicorandil plus standard treatment was associated with reduced total mortality in both PPCI and EPCI, CV death in EPCI, and heart failure in PPCI. Nicorandil is associated with lower risks of total mortality and CV death in PPCI and EPCI in those who received nicorandil > 28 days.Nicorandil as an adjunct therapy along with PCI is associated with reduced total mortality and cardiovascular death in PPCI and EPCI patients, and reduced heart failure in PPCI patients.

Autologous stem cell therapy for peripheral arterial disease: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Peripheral arterial disease (PAD) is a common cause of disability and mortality. The reconstruction of blood circulation presents to be the key to treatment, which can be achieved by surgery and interventional therapy. Since 40% patients have lost the chance for the therapy, a new method is needed to reduce the amputation and mortality rate for "no-option" patients. The objective of our systematic review and meta-analysis was to evaluate the efficacy and safety of autologous implantation of stem cells in patients with PAD critically, compared with active controls and placebo. METHODS: Randomized controlled trials (RCTs) of autologous implantation of stem cells compared with placebo and control for PAD were included. Electronic medical databases including MEDLINE, Embase, the Cochrane Central Register of Controlled Trials (CENTRAL), the Chinese Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), and ClinicalTrials.gov were searched from initial period to September 2018. Independently, two reviewers screened citations, extracted data, and assessed the risk of bias according to the criteria of the Cochrane handbook. The quality of evidence was evaluated by GRADE evidence profile. The primary outcomes consisted of amputation rate, major amputation rate, ulcer healing rate, and side effects. The second outcomes included ankle-brachial index (ABI), transcutaneous oxygen tension (TcO2), pain-free walking distance (PFWD), and rest pain score. Statistical analysis was conducted via RevMan 5.3 and Stata 12.0. RESULTS: According to the twenty-seven RCTs, 1186 patients and 1280 extremities were included and the majority of studies showed a high risk of bias. Meta-analysis indicated that autologous stem cell therapy was more effective than conventional therapy on the healing rate of ulcers [OR = 4.31 (2.94, 6.30)]. There was also significant improvement in ABI [MD = 0.13 (0.10, 0.17)], TcO2 [MD = 0.13 (0.10, 0.17)], and PFWD [MD = 178.25 (128.18, 228.31)] while significant reduction was showed in amputation rate [OR = 0.50 (0.36, 0.69)] and rest pain scores [MD = - 1.61 (- 2.01, - 1.21)]. But the result presented no significant improvement in major limb salvage [0.66 (0.42, 1.03)]. Besides, stem cell therapy could reduce the amputation rate [OR = 0.50 (0.06, 0.45] and improve the ulcer healing rate [OR = 4.34 (2.96, 6.38] in DM subgroup. Eight trials reported the side effects of autologous stem cell therapy, and no serious side effects related to stem cells were reported. GRADE evidence profile showed all the quality evidence of outcomes were low. CONCLUSIONS: Based on the review, autologous stem cell therapy may have a positive effect on "no-option" patients with PAD, but presented no significant improvement in major limb salvage. However, the evidence is insufficient to prove the results due to high risk of bias and low-quality evidence of outcomes. Further researches of larger, randomized, double-blind, placebo-controlled, and multicenter trials are still in demand.

Characteristics of lipid profiles and lipid control in patients with diabetes in a tertiary hospital in Southwest China: an observational study based on electronic medical records.

BACKGROUND: Diabetes is often accompanied by dyslipidemia. Lipid control is very important in the management of diabetes. There are limited real world data on the lipid control in diabetic inpatients in southwest China. METHODS: An observational study was conducted to assess the characteristics of lipid profiles and lipid control. Diabetic patients from February 2009 to December 2013 at West China Hospital of Sichuan University were identified. RESULTS: A total of 56,784 inpatients were included and 85.9% of them had at least one lipid panel. The proportions of inpatients with optimal low-density lipoprotein cholesterol (LDL-C) level (< 2.59 mmol/L), optimal triglyceride (TG) level (< 1.70 mmol/L), optimal high-density lipoprotein cholesterol (HDL-C) level (men ≥1.04 mmol/L; women ≥1.30 mmol/L) and optimal non-high-density lipoprotein cholesterol (non-HDL-C) level (< 3.37 mmol/L) were 61.1, 64.6, 49.9 and 64.5%, respectively. Only 23.1% of inpatients obtained optimal levels for all the above four lipid parameters. Of diabetic inpatients with ischemic heart disease, the proportions of inpatients with optimal LDL-C level (< 1.81 mmol/L), optimal TG level (< 1.70 mmol/L), optimal HDL-C level (men ≥1.04 mmol/L; women ≥1.30 mmol/L) and optimal non-HDL-C level (< 2.59 mmol/L) were 38.0, 66.3, 48.1 and 48.7%, respectively. Of diabetic inpatients with cerebrovascular disease, the proportions were 28.3, 64.8, 49.9 and 38.1%, respectively. Older people and men were more likely to obtain optimal lipid levels. However, inpatients between 46 and 64 years were least likely to obtain optimal LDL-C levels. CONCLUSIONS: The lipid control of diabetic inpatients in southwest China is worrisome. Individualized strategies of lipid management should be taken to bridge the gap between the recommendations of clinical guidelines and the real situation of clinical practice.

Early diagnosis of trisomy 21, trisomy 18 and trisomy 13 using nuchal translucency thickness and ductus venosus blood flow waveform in West China.

Abnormal nuchal translucency (NT) thickness and ductus venosus (DV) blood flow have been associated with trisomy 21, 18 and 13. However, the association of abnormal DV with these aneuploidies varies among clinical studies. The present study examined the possibility of using NT combined with DV for the early diagnosis of the three aforementioned aneuploidies in the Western Chinese population, focusing on three aspects: Biological pathway analysis, theoretical statistical analysis and clinical data analysis from 1,962 first­trimester pregnant women from Western China. The pathway and statistical analyses performed suggested the reliability of integrating NT and DV in the prediction of the three aneuploidies. The clinical data analysis suggested that integrating NT and DV, compared with NT alone, resulted in increased predictive power (34.09 vs. 22.45%), better rejection probability (0.21 vs. 0.44%), increased specificity (96.71 vs. 94.07%) and increased sensitivity (89.47 vs. 80.49%). The present results suggested the reliability of integrating NT and DV for the early diagnosis of trisomy 21, 18 and 13 for the Western Chinese population. The present results provided novel statistical analyses to the field of prenatal diagnosis in the Western Chinese population.

Autologous platelet-rich gel treatment for diabetic chronic cutaneous ulcers: A meta-analysis of randomized controlled trials.

BACKGROUND: In recent years, many studies have reported that autologous platelet-rich gel (APG) is an effective adjuvant treatment for chronic cutaneous ulcers in diabetics. The aim of this study was to explore the efficacy and safety of APG for the topical treatment of diabetic chronic cutaneous ulcers. METHODS: The China Biology Medicine (CBM), China National Knowledge Infrastructure (CNKI), VIP Database for Chinese Technical Periodicals (VIP), Chinese Wanfang database, PubMed, EMBASE, EBSCOhost, and Cochrane Library were systematically searched for relevant studies published up to 18 October 2017. Fixed- and random-effects models were used to calculate risk ratios (RR), odds ratios (ORs), and mean difference (MD) with 95% confidence intervals (95% CI). Subgroup analyses were conducted according to the Diabetic Foot Wagner Classification. RESULTS: Fifteen randomized control trials (RCTs) with 829 patients were eligible for inclusion in this analysis. Compared with standard care or conventional treatment, APG significantly improved the healing rate (RR 1.39; 95% CI 1.29, 1.50; P < 0.00001), shortened the healing time (MD -9.18; 95% CI -11.32, -7.05; P < 0.00001), and reduced the incidence of infection (OR 0.34; 95% CI 0.15, 0.77; P = 0.009). CONCLUSIONS: Current evidence suggests that APG is effective and safe, and is feasible for use as an adjuvant treatment for diabetic ulcers, especially chronic refractory ulcers. However, more RCTs with a good design and of a high quality are needed before the use of APG can be implemented widely.

Different regimens of penicillin antibiotics given to women routinely for preventing infection after cesarean section: A systematic review and meta analysis.

BACKGROUND: Varied regimens of penicillin antibiotics were given to women for preventing infection after cesarean section, but there is no study compares the effectiveness and safety of them. METHODS: We searched MEDLINE, Embase, CENTRAL, CNKI, Wanfang, VIP, and CBM Database, and contacted experts in the field and searched reference lists of retrieved studies. We included randomized controlled trials comparing different regimens of penicillin antibiotics given to women after cesarean section. Two review authors independently assessed the studies for inclusion, assessed risk of bias, and carried out data extraction. RESULTS: A total of 18 randomized controlled trails (involving 3287 pregnant women) were eligible. Compared with after umbilical cord clamping, penicillin antibiotics prophylaxis before skin incision could reduce the risk of endometritis for women undergoing cesarean. Compared with using penicillin antibiotics alone, using antibiotic-inhibitor combination could reduce the risk of endometritis or fever. No statistically significant difference was present between single-dose versus multidose, short term versus long term, intravenous injection versus lavag in the risk of reported outcomes. CONCLUSION: There is insufficient evidence to draw certain conclusions on which regimen of penicillin antibiotics is the best in this review. Further studies should pay attention to the study design, and besides the outcomes of pregnant women, researchers should focus on the outcomes of newborns.

Study design and baseline characteristics of inpatients with diabetes mellitus in a tertiary hospital in China: A database study based on electronic medical records.

AIM: To describe the characteristics of inpatients with diabetes in a tertiary hospital in China using an electronic medical record (EMR)-based database. METHODS: We identified the medical records of all patients with diabetes from nonpediatric departments of West China Hospital, Sichuan University (from February 2009 to December 2013), and extracted information on demographic, diagnosis, discharge outcome, department of discharge, laboratory test, and prescription from the EMR system. The quality of the database was assessed by analyzing missing data and extreme data and by reviewing the International Classification of Diseases 10th Revision (ICD-10) coding. RESULTS: Among 683,267 discharged patients, 56,784 (8.3%) patients diagnosed with diabetes were identified from all departments. Among the patients with diabetes, the average age was 63.5 ± 13.1 years and the overall death in hospital was 2.2%. Laboratory test results were highly completed in our database with no extreme or discrepant value identified. Anthropometric parameters were of a relatively low quality as 62.2% body-mass index data were missing. HbA1c levels at admission were available for 36.7% patients with diabetes. The ICD-10 coding of the diagnosis of diabetes was accurate in 88.6% records reviewed. Dyslipidemia (76.5%), hypertension (51.3%), chronic kidney disease (22.1%), and hyperuricemia (16.2%) were the most commonly presented comorbidities among inpatients with diabetes. CONCLUSIONS: Our study indicated a wide distribution of diabetes throughout the inpatients in a tertiary hospital in southwest China. This EMR-based database of diabetes could be potentially useful in further investigations.

Guideline use behaviours and needs of primary care practitioners in China: a cross-sectional survey.

OBJECTIVES: Clinical guidelines have been recognised as an effective way to improve healthcare performance. However, little is known about the uptake and implementation of guidelines by general practitioners in China. The aim of this study was to investigate the guideline use behaviours and needs of practitioners in primary care settings in China. METHODS: We conducted a cross-sectional survey from December 2015 to May 2016 that included practitioners at 268 institutions in 15 provinces in China. Questionnaire development was informed by the execution of a literature review and consultation of experts. On-site surveys were implemented using a paper questionnaire to minimise missing responses. A multivariate logistic regression analysis was performed to identify factors associated with provider knowledge of and attitudes towards clinical guidelines. RESULTS: Of the respondents, 91.7% (1568/1708) were aware of clinical guidelines, but only 11.3% (177/1568) frequently used them. The main mechanism by which primary care practitioners accessed guidelines was public search engines (63.4%; 911/1438), and practitioners seldom reported using biomedical databases. The most frequently identified barriers to guideline use were lack of training (49.9%; 778/1560), lack of access (44.6%; 696/1560) and lack of awareness (38.0%; 592/1560). Less than one-quarter of respondents considered current guidelines 'entirely appropriate' for use in primary care (23.5%; 339/1442). Most participants (96.2%; 1509/1568) believed it was necessary to develop primary care guidelines. Provider attitudes towards current guidelines were associated with the location and level of the institution and professional title of the practitioner (p<0.05). CONCLUSION: Our survey revealed poor knowledge and uptake of clinical guidelines in primary care, and we identified a gap between the needs of practitioners and availability of clinical guidelines for use in primary care in China. In addition, lacking access to and training in guidelines also prevented primary healthcare practitioners from using guidelines in daily practice.

[Study on Relationship Between Serum 25-hydroxyvitamin D3 Concentration and Glucose Metabolism].

OBJECTIVES: To investigate the relationship between serum 25-hydroxyvitamin D3 [25(OH)D3 ] concentration and glucose metabolism. METHODS: This cross-sectional survey recruited 668 participants, and the demographic and clinical characteristics of the participants were obtained from questionnaires. Physical examination and blood biochemical examination were performed, then the participants were divided into three groups as normal glucose tolerant (NGT) group, impaired glucose regulation(IGR) group, and diabetes mellitus (DM) group. RESULTS: There was no statistical significant difference in serum 25(OH)D3 concentration among the three groups ( P>0.05). With comparison of different serum 25(OH) D3 concentration, there was no statistical significant difference in the incidence of DM and IGR, FPG, 2 h BG, HOMA-IR, ISI-composite, HOMA-ß or ΔI30/ΔG30 ( P>0.05). Serum 25(OH)D3 concentration was not associated with DM, IGR, FPG, 2 h BG, HOMA-IR, ISI-composite, HOMA-ß or ΔI30/ΔG30 ( P>0.05). CONCLUSIONS: No relationship between serum 25(OH)D3 concentration and glucose metabolism is comfirmed.

The Validity and Reliability between Automated Oscillometric Measurement of Ankle-Brachial Index and Standard Measurement by Eco-Doppler in Diabetic Patients with or without Diabetic Foot.

OBJECTIVE: To evaluate the concordance between oscillometric ABI and standard Doppler ABI in diabetic Chinese patients with or without diabetic foot. METHODS: 230 consecutive diabetic patients (n = 459 limbs) were included. The right and left ABIs were determined with both devices by the same investigator. The concordance and agreement were assessed by kappa index and the Bland-Altman method. RESULTS: The average Doppler ABI was 1.003 ± 0.286 on the right and 0.990 ± 0.287 on the left, while oscillometric ABI was 1.002 ± 0.332 and 0.993 ± 0.319, which had no significance. The average time for oscillometric ABI was 8.600 versus 16.980 minutes for Doppler ABI (p < 0.001). There was good agreement between the two measurements, with a kappa value of 0.869 on the right and 0.919 on the left. Regarding the Doppler ABI as the gold standard, the accuracy, sensitivity, specificity, +LR, and -LR of oscillometric ABI reached 95.22%, 94.34%, 95.48%, 20.873%, and 0.059% on the right. For the left, it was 96.94%, 96.43%, 97.11%, 33.364%, and 0.036%. CONCLUSIONS: The oscillometric measurement is a reliable, convenient, and less time-consuming alternative to standard Doppler ABI in patients. It should be widely used for PAD detection.
