Comparison of efficacy and safety of empagliflozin vs linagliptin added to premixed insulin in patients with uncontrolled type 2 diabetes: A randomized, open-label study.

AIMS: Sodium-glucose cotransporter-2 (SGLT2) inhibitors and dipeptidyl peptidase (DPP)-4 inhibitors added to insulin regimens in patients with type 2 diabetes mellitus (T2DM) can improve glycaemic control. This study compared the efficacy and safety of empagliflozin and linagliptin added to premixed insulin therapy in patients with poorly controlled T2DM. METHODS: In this 24-week, open-label, parallel-design randomized controlled trial, patients with poorly controlled T2DM despite a premixed insulin regimen were randomized to receive 5mg of linagliptin (n=53) or 25mg of empagliflozin (n=53) for 24 weeks. RESULTS: At week 24, changes in glycated haemoglobin (HbA1c) from baseline were -0.06±0.17% and -1.01±0.16% in the linagliptin and empagliflozin groups, respectively, and the mean treatment HbA1c difference was -0.88% (95% CI: -1.33, -0.43). At week 24, the empagliflozin group showed significant reductions, compared with the linagliptin group, in fasting plasma glucose (P<0.001), body weight (P<0.001), systolic blood pressure (P=0.003) and total daily insulin dose (P=0.042). Hypoglycaemia was reported to be slightly, and not significantly, higher in the empagliflozin group vs linagliptin group (30.2% vs 22.6%, respectively; P=0.51). Similar percentages of patients (1.9%) had urinary tract infections in the two groups. CONCLUSION: In Asian patients with inadequately controlled T2DM while taking premixed insulin, the addition of empagliflozin for 24 weeks provided better glycaemic control and greater reductions in body weight and systolic blood pressure than the addition of linagliptin. Clinical Trial Registration #: NCT03458715.

First trimester placental vascular indices and volume by three-dimensional ultrasound in pre-gravid overweight women.

OBJECTIVES: To investigate changes of placental vascular indices and volume in pre-gravid overweight Chinese women during the first trimester using three-dimensional power Doppler ultrasound. METHODS: This was a prospective observational study of the morphology of placentas in pre-gravid overweight (body mass index (BMI) ≥ 24 kg/m2) and non-overweight (BMI < 24 kg/m2) Chinese women during the first trimester of pregnancy. Data on placental vascular indices (vascularization index, flow index, and vascularization flow index (VFI)), placental volume, uterine artery pulsatility index (PI), and neonatal outcomes were obtained during the first trimester and analyzed. Linear regression analysis was used to evaluate confounding factors between BMI and ultrasound indices. RESULTS: Of the 429 pregnant women enrolled, 68 (15.9%) were pre-gravid overweight. Placental VFI was significantly lower in the overweight group (p = 0.037). Conversely, placental volume was significantly larger in the overweight group (p = 0.044), and uterine artery PI was significantly higher in the overweight group (p = 0.021). After adjustments for confounding factors, there were still significant differences in placental VFI (unstandardized coefficient (B) -0.666, 95% confidence interval (CI) -1.306 - (-0.025)), placental volume (B 2.458, 95% CI 0.071-4.844), and uterine artery PI (B 0.152, 95% CI 0.030-0.274) between the two groups. CONCLUSIONS: Placental vascular indices using three-dimensional power Doppler ultrasound can provide an insight into placental vascularization in pre-gravid overweight women in early pregnancy. Alterations in placental VFI, placental volume, and uterine artery PI occur during the first trimester in pre-gravid overweight women.

[Clinical features and laboratory data analysis of Aeromonas bacteremia with hematological diseases].

Objective: To investigate the clinical and laboratory features of Aeromonas bacteremia in patients with hematological diseases, and provide evidence for the prevention and treatment of Aeromonas infection. Methods: A retrospective study of patients with bloodstream infection of Aeromonas in our hospital from January 2014 to December 2018 was carried out. The clinical characteristics, antimicrobial susceptibility, infection seasons, antimicrobial therapy and evolution were analyzed. Results: A total of 42 patients with hematological diseases had Aeromonas bloodstream infection within 5 years. Among them, 39 cases (92.9%) of bloodstream infection occurred in the stage of neutropenia. The median time of fever was 4 (1-27) d, 22 (52.4%) patients only had fever, 6 (14.3%) with gastrointestinal symptoms (abdominal pain, diarrhea, nausea, upper gastrointestinal bleeding) , 8 (19.0%) with pulmonary infection, 13 (31.0%) with skin and soft tissue infections. Seven patients (16.7%) died with skin and soft tissue infection. The resistance of Aeromonas to carbapenems was 68.3%-70.7%, while the resistance rate to cephalosporins, quinolones and aminoglycosides were less than 10%. Conclusions: Aeromonas bacteremia in patients with hematological diseases mainly occur in the neutropenia stage, usually with symptom like fever. The mortality is increased when accompanied by skin and soft tissue infection. Antibiotic use should be based on susceptibility results, and avoid the use of carbapenems.

Clinicopathological and prognostic significance of preoperative serum epidermal growth factor levels in patients with oral squamous cell carcinoma.

Epidermal growth factor (EGF) promotes tumourigenesis and tissue repair of epithelial and mesenchymal cells and has a role in chemotaxis, mitogenesis, cell motility, and cytoprotection. It also enhances the growth of cancers. EGF may therefore have a role in the initiation or promotion of oral carcinogenesis. The cases of 152 patients with oral squamous cell carcinoma whose preoperative serum EGF level was determined by enzyme-linked immunosorbent assay were analyzed retrospectively, along with those of 40 age- and sex-matched controls. Patients with higher levels of EGF were more likely to have neck lymph node metastasis (P=0.026), advanced stage cancer (P=0.04), and a worse survival status (P=0.0019). Multivariate analysis using the Cox proportional hazards model indicated that the EGF level was an independent predictor of poor survival (hazard ratio 1.99, P=0.018). Patients with higher preoperative serum EGF levels had significantly poorer cancer-specific survival by Kaplan-Meier analysis (P=0.032). This study indicates that a higher preoperative serum EGF level is associated with neck lymph node metastasis, more advanced stage, and poor survival. EGF should be considered as a potential prognostic biomarker and a therapeutic target for patients with oral cancer.

[Perianal swabs surveillance cultures of Carbapenem-resistant Enterobacteriaceae(CRE) can be hints for CRE bloodstream infection in patients with hematological diseases].

Objective: To analyze the hints role of surveillance cultures of Carbapenem-resistant Enterobacteriaceae (CRE) by perianal swabs in patients with hematological diseases, and seek risk factors of CRE bloodstream infection. Methods: The resistance of CRE from 2 914 patients with hematological diseases who cultured perianal swabs, CRE bloodstream infection and risk factors were analyzed during January 2016 to December 2017. Results: In this study, perianal swabs from 2 914 patients with hematological diseases were cultured, 74 patients were CRE positive, and bloodstream infection with CRE was found in 13 of these patients. A total of 87 CRE strains were isolated (The same patient only keep the first one for the same location), including 31 Klebsiella pheuminiae, 43 Escherichia coli, 8 Enterobacter cloacae and 6 other Enterobacteriaceae. The resistance rates to piperacillin / tazobactam, imipenem, meropenam, amikacin, levofloxacin, tigecycline were 91.9%, 74.4%, 98.8%, 17.6%, 74.4% and 8.0%, respectively. Resistance to carbapenem, aminoglycoside, quinolones and tegacycline were highly consistent between two sites from 13 patients, whose both perianal swabs and blood were positive in CRE cultures. Febrile neutropenic time, digestive tract symptoms and perianal infection were independent risk factors for bloodstream infection in patients with perianal swabs positive results, the odds ratios (OR) were 1.10 (P=0.029), 1.13 (P=0.005) and 1.23 (P=0.016), respectively. Conclusion: Perianal swabs surveillance cultures of CRE can be hints for CRE bloodstream infection in patients with hematological diseases, and also can provide suggestions for antibiotics. Long time of febrile neutropenic, digestive tract symptoms and perianal infection can be the early warning for CRE bloodstream infections.

Association between ADAM metallopeptidase domain 33 gene polymorphism and risk of childhood asthma: a meta-analysis.

This study aimed to investigate the association between ADAM metallopeptidase domain 33 (ADAM33) gene polymorphisms and the risk of childhood asthma. The relevant studies about the relationship between ADAM33 gene polymorphisms and childhood asthma were searched from electronic databases and the deadline of retrieval was May 2016. The single nucleotide polymorphisms (SNPs) of ADAM33 (rs511898, rs2280092, rs3918396, rs528557, rs2853209, rs44707, rs2280091 and rs2280089) were analyzed based on several models including the allele, codominant, recessive and dominant models. The results showed that the ADAM33 rs2280091 polymorphism in all four genetic models was associated with an increased risk of childhood asthma. Positive associations were also found between the polymorphisms rs2280090, rs2787094, rs44707 and rs528557 and childhood asthma in some genetic models. This meta-analysis suggested that ADAM33 polymorphisms rs2280091, rs2280090, rs2787094, rs44707 and rs528557 were significantly associated with a high risk of childhood asthma.

[Analysis for serological diagnostic results of syphilis among entry personnel in Beijing port during 2012-2014].

OBJECTIVE: To analyze the results of syphilis specific serological tests among entry personnel in Beijing port during year 2012-2014 in order to provide evidence for the prevention and control of syphilis. METHODS: Demographics data and syphilis specific test results of entry personnel were obtained from the information system of Beijing International Travel Healthcare Center and input into Excel 2016. Database for entry personnel was built up accordingly and was analyzed by IBM SPSS22.0. RESULTS: The number of entry personnel in Beijing port during year 2012-2014 was 106 302 person-time. According to the evaluation criteria, 71 308 persons were recruited and analyzed, of whom 277 were tested serologically positive and the total prevalence was 0.39% (95% CI: 0.34%-0.43%). The prevalence was highest in the persons aged 40-49 years (0.81%) and was higher in males (0.50%) than in females (0.23%). The persons from Africa held higher prevalence (1.27%) than from other five regions. As multivariate logical regression analysis indicated that the risk of syphilis infection was 10.38 times more in the persons aged 40-49 years than in the persons <20 years (95%CI:5.59-19.28), and 1.85 times more in males than in females (95%CI: 1.40-2.44). For the people from Africa, South America and Asia, the infection risks were respectively 4.89 times (95%CI: 2.97-8.06), 4.82 times (95%CI: 2.39-9.74) and 1.72 times (95%CI: 1.15-2.59) more than that for the people from North America. Rising trend of the prevalence was observed in both genders by age groups (P value for trend χ(2)<0.05). Except for Asia, the prevalences of the people from other five regions were rising slightly by years, however there were no obvious trends (P value for trend χ(2)>0.05). Twenty-seven seropositive cases were found within 6 246 entry persons who were tested repeatedly during the research period, 9 of which were seroconversion cases so that the cumulative conversion rate was 0.14% (9/6 228). The average conversion time was (6.3±3.0) months. There was no statistical significance between the cumulative seroconversion rates of the persons with different genders and nationalities (P of Fisher's exact test>0.05). CONCLUSION: Serological detection of syphilis for entry personnel in Beijing port and syphilis-related health education should be reinforced to reduce the risk of disease importing and spreading, protect susceptible subjects and promote health.

Clinical application of total parenteral nutrition in patients with peritoneal carcinomatosis.

Cancer patients with terminal stage peritoneal carcinomatosis are often unable to eat, rendering total parenteral nutrition (TPN) as the only option to avoid starvation. In this retrospective study, we reviewed the medical records of 46 patients with peritoneal carcinomatosis and compared them to the records of 51 patients who had gastrointestinal malignancy without evidence of peritoneal carcinomatosis. The factors evaluated include demographic data, cause of primary malignancy, ascites formation, anthropometric measurements, laboratory tests, and outcome measurements as well as factors associated with greater than 90-day survival. In-hospital mortality was observed in 31 of the 46 patients with peritoneal carcinomatosis, with a median survival time of 40 days (4-148 days) for all 46 patients. The median duration of TPN administration in the peritoneal carcinomatosis group was 24.1 ± 27.4 days (3-68 days). Severe infection related to TPN application was seen in 5/46 (10.7%) patients with peritoneal carcinomatosis and 6/51 (9.8%) patients without peritoneal carcinomatosis. The length of survival varied widely among terminal patients with peritoneal carcinomatosis. The average survival time in peritoneal carcinomatosis patients receiving TPN was short, indicating that the nutrition support of TPN was relatively suboptimal. Ascites was not a prognostic factor for peritoneal carcinomatosis, while body mass index was a predictor for 90-day survival.

Effect of sheep and human follicular fluid on the maturation of sheep oocytes in vitro.

This study examines the effect of sheep and human follicular fluid on the in vitro maturation (IVM) of sheep follicular oocytes. Oocyte cumulus complexes recovered post mortem were matured for 24 to 26 h at 38.6 degrees C, 5% CO(2) in air, in TCM-199 bicarbonate medium supplemented with 20% fetal calf serum (FCS) and, where stated, with maturation hormones, including FSH (5.0 microg/ml), LH (5.0 microg/ml) and estradiol (1 microg/ml), or with sheep follicular fluid recovered from large (>5 mm) or small (2 to 5 mm) ovarian follicles post mortem, or with human periovular follicular fluid obtained during routine IVF procedures. The matured oocytes were then denuded, and their maturation stage and developmental capacity were assessed by in vitro fertilization (IVF) and culture (IVC). It was found that inclusion of sheep or human follicular fluid or hormone supplements in the IVM media more than doubled the number of oocytes completing maturation (FCS alone 33%, compared with 76.2% for maturation hormones, 84.2% for fluid from large and 69.6% for fluid from small sheep follicles and 82.6% for human follicular fluid), and significantly increased fertilization rates (FCS alone 51.6%, compared with 71.9% for maturation hormones, 78.4% for fluid from the large and 75.7% for fluid from small sheep follicles and 73.1% for human follicular fluid) without discernible adverse effects on the development of the cleaving embryos to the morula or blastocyst stage in culture. Omission of FCS and supplements from the IVM medium resulted in a marked reduction (56%) in the number of oocytes maturing. This reduction could be offset to a large part, but not completely, by inclusion of human follicular fluid or human follicular fluid plus LH (5 microg/ml) in the medium. The results of this study show that addition of sheep or human follicular fluid to maturation medium can enhance rather than inhibit the maturation and fertilizability of sheep follicular oocytes in vitro.
