Comparison of two titration programmes for adding insulin detemir to oral antidiabetic drugs in patients with poorly controlled type 2 diabetes mellitus.

AIM: To explore the effect of active insulin titration versus usual titration on glycaemic control in patients with type 2 diabetes mellitus uncontrolled with oral antidiabetic drugs (OADs). METHODS: In a 24-week, prospective and randomized study, 172 patients with uncontrolled type 2 diabetes were randomly assigned to either active titration or usual titration. Efficacy and safety outcomes included changes in glycated haemoglobin (HbA1c) and fasting plasma glucose, percentage of individuals achieving HbA1c<53 mmol/mol, and hypoglycaemic events. RESULTS: At Week 24, change in HbA1c was -1.08% ± 1.60% in the active titration group and -0.95% ± 1.34% in the usual titration group (P = 0.569). The percentages of individuals achieving HbA1c<53 mmol/mol were 29.4% and 16.1% in the active and usual titration groups, respectively (P = 0.037). There was no significant difference in the incidence of hypoglycaemia between the two groups. Multivariate logistic regression indicated that, with active titration, baseline HbA1c levels and postprandial glucose excursion were significantly associated with achieving HbA1c<53 mmol/mol. CONCLUSION: Addition of basal insulin using active titration for 24 weeks provided a higher rate of HbA1c target achievement without significant hypoglycaemia compared to usual titration in individuals with uncontrolled type 2 diabetes.

TTAS: Trusted Token Authentication Service of Securing SCADA Network in Energy Management System for Industrial Internet of Things.

The vigorous development of the Industrial Internet of Things brings the advanced connection function of the new generation of industrial automation and control systems. The Supervisory Control and Data Acquisition (SCADA) network is converted into an open and highly interconnected network, where the equipment connections between industrial electronic devices are integrated with a SCADA system through a Modbus protocol. As SCADA and Modbus are easily used for control and monitoring, the interconnection and operational efficiency between systems are highly improved; however, such connectivity inevitably exposes the system to the open network environment. There are many network security threats and vulnerabilities in a SCADA network system. Especially in the era of the Industrial Internet of Things, any security vulnerability of an industrial system may cause serious property losses. Therefore, this paper proposes an encryption and verification mechanism based on the trusted token authentication service and Transport Layer Security (TLS) protocol to prevent attackers from physical attacks. Experimentally, this paper deployed and verified the system in an actual field of energy management system. According to the experimental results, the security defense architecture proposed in this paper can effectively improve security and is compatible with the actual field system.

Evaluation of chronic stress status and quality of life in cats suffering from chronic kidney disease and suspected feline infectious peritonitis based on hair cortisol concentration analysis and a questionnaire.

Hair cortisol concentration (HCC) and a questionnaire were used as indicators of chronic stress status and quality of life (QoL), respectively, in cats. To date, there has been limited research on the simultaneous application of both indicators in unwell cats. Our aim was to evaluate HCC and questionnaire data obtained from a healthy cat cohort (n = 61) and cat cohorts with either chronic kidney disease (CKD) (n = 78) or suspected feline infectious peritonitis (FIP) (n = 24). Furthermore, we also investigated the correlation between HCC and clinical pathological data. For this study, hair from the abdomen of cats was collected and analyzed for HCC using a commercial ELISA kit. Owners also completed a questionnaire, from which average-item-weighted-impact-scores (AWISs) were calculated. Cats with late-stage-CKD (median, HCC = 330.15 pg/mg, AWIS = -0.43) presented with a significantly higher HCC (p < 0.01) and a significantly lower AWIS (p < 0.01) than cats with early-stage-CKD (HCC = 183.56 pg/mg, AWIS = 1.08). Similarly, there were significant differences in both HCC (p < 0.001) and AWIS (p < 0.001) between cats with suspected FIP (HCC = 896.27 pg/mg, AWIS = -1.97) and healthy cats (HCC = 181.24 pg/mg, AWIS = 1.24). The degree of consistency between the HCC results and the questionnaire results reminds us that the severity of a chronic disease or the presence of a life-threatening disease can significantly increase stress and thus can affect the QoL of cats.

Prognostic factors and outcomes of invasive pulmonary aspergillosis, a retrospective hospital-based study.

Objective: Invasive pulmonary aspergillosis (IPA) affects immunocompromised hosts and is associated with higher risks of respiratory failure and mortality. However, the clinical outcomes of different IPA types have not been identified. Methods: Between September 2002 and May 2021, we retrospectively enrolled patients with IPA in Taichung Veterans General Hospital, Taiwan. Cases were classified as possible IPA, probable IPA, proven IPA, and putative IPA according to EORTC/MSGERC criteria and the AspICU algorithm. Risk factors of respiratory failure, kidney failure, and mortality were analyzed by logistic regression. A total of 3-year survival was assessed by the Kaplan-Meier method with log-rank test for post-hoc comparisons. Results: We included 125 IPA patients (50: possible IPA, 47: probable IPA, 11: proven IPA, and 17: putative IPA). Comorbidities of liver cirrhosis and solid organ malignancy were risk factors for respiratory failure; diabetes mellitus and post-liver or kidney transplantation were related to kidney failure. Higher galactomannan (GM) test optical density index (ODI) in either serum or bronchoalveolar lavage fluid was associated with dismal outcomes. Probable IPA and putative IPA had lower 3-year respiratory failure-free survival compared to possible IPA. Probable IPA and putative IPA exhibited lower 3-year renal failure-free survival in comparison to possible IPA and proven IPA. Putative IPA had the lowest 3-year overall survival rates among the four IPA groups. Conclusion: Patients with putative IPA had higher mortality rates than the possible, probable, or proven IPA groups. Therefore, a prompt diagnosis and timely treatment are warranted for patients with putative IPA.

The accuracy of magnetic resonance cholangiopancreatography in the diagnosis of biliary atresia in preterm infants with cholestasis.

BACKGROUND: Magnetic resonance cholangiopancreatography (MRCP) is a useful and non-invasive method to diagnose biliary atresia (BA) in term infants, however few studies have investigated its use in preterm infants. This study aimed to evaluate the accuracy of MRCP in the diagnosis of BA in preterm infants with cholestasis. METHODS: Infants aged less than 6 months who received MRCP for cholestasis at a tertiary medical center were enrolled from 2011 to 2020. Demographic and laboratory data were retrospectively obtained. One pediatric radiologist reviewed the MRCP images. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of MRCP to diagnose BA based on surgical proof or at least 6 months of follow-up were assessed. RESULTS: A total of 80 infants (36 preterm and 44 term) were analyzed. The mean post-chronological age was 1.8 months, and the female-to-male ratio was 0.78. Six (16.7%) preterm and 16 (36.4%) term infants were confirmed to have BA. BA was obscured by a choledochal cyst preoperatively in two term infants. In the preterm infants, the sensitivity, specificity, PPV, NPV, and accuracy of MRCP to diagnose BA were 100%, 77%, 46%, 100%, and 81%, respectively, compared to 81%, 86%, 76%, 89%, and 84% in the term infants. Using MRCP to differentiate BA from other cholestasis in the preterm infants had superior sensitivity (100% vs. 81%) and NPV (100% vs. 89%), and lower specificity (77% vs. 86%) and PPV (46% vs. 76%) than in the term infants. CONCLUSIONS: Negative MRCP findings can be used to exclude BA in preterm infants with cholestasis based on a favorable NPV.

The Characteristics and Risk Factors of Asparaginase-Associated Pancreatitis in Pediatric Acute Lymphoblastic Leukemia.

OBJECTIVE: This study aimed to elucidate the characteristics and the risk factors for asparaginase-associated pancreatitis (AAP) in pediatric acute lymphoblastic leukemia (ALL) under the Taiwan Pediatric Oncology Group (TPOG)-ALL regimen. METHODS: The study was conducted by reviewing the chart records of 191 patients aged 1 to 18 years treated with TPOG-ALL (2002 and 2013) protocols at the National Cheng Kung University Hospital, Tainan, Taiwan, from 2002 to 2019. The disease incidence, clinical presentations, laboratory data, complications, and outcomes of AAP were investigated. RESULTS: The incidence of AAP was 4.7%. The incidence was significantly higher in children treated with the TPOG-ALL-2013 (n = 62) than TPOG-ALL-2002 (n = 129) protocol (11.3% vs 1.6%, P = 0.006). Multivariate analysis identified using TPOG-ALL-2013 protocol was an independent risk factor for AAP. Pancreatic necrosis or pseudocysts developed in 7 patients (78%). Notably, 1 AAP case (11%) developed diabetes mellitus and 4 (44%) had chronic pancreatitis during a 1-year observational period. None were mortality. CONCLUSIONS: The incidence of AAP was 4.7% in ALL patients treated with TPOG-ALL protocol. Although a higher cumulative dose of asparaginase in TPOG-ALL-2013 may attribute to the pancreatic toxicity, unidentified factors such as genetic predisposition or other drugs still need further study.

Efficacy and safety of adding pioglitazone or sitagliptin to patients with type 2 diabetes insufficiently controlled with metformin and a sulfonylurea.

OBJECTIVE: To evaluate the efficacy and safety of add-on pioglitazone versus sitagliptin in patients with type 2 diabetes inadequately controlled on metformin and a sulfonylurea (SU). METHODS: This 24-week, randomized, open-label study compared pioglitazone (30 mg daily, n = 59) and sitagliptin (100 mg daily, n = 60) in patients with inadequate glycemic control (glycosylated hemoglobin [HbA1c] ≥7.0% to <11.0%) while receiving a stable dose of metformin (≥1,500 mg daily) and an SU (≥half-maximal dose). RESULTS: The mean changes in HbA1c from baseline was -0.94 ± 0.12% with pioglitazone and -0.71 ± 0.12% with sitagliptin, for a between-groups difference of -0.23 ± 0.16% (P = .16). The mean change in fasting plasma glucose (FPG) were -35.7 ± 4.0 mg/dL with pioglitazone and -22.8 ± 4.0 mg/dL with sitagliptin, for a between-groups difference of -12.9 ± 5.7 mg/dL (P = .02). Pioglitazone was associated with a significant decrease in high-sensitive C-reactive protein (hs-CRP), but sitagliptin did not. The mean weight gain was higher in the pioglitazone group, with a between-group difference of 1.6 kg (P<.01). Overall adverse events (AEs) were similar in both groups. However, the incidence of edema was higher with pioglitazone, and the incidence of gastrointestinal AEs was higher with sitagliptin. CONCLUSION: Pioglitazone and sitagliptin achieved similar improvements in overall glycemic control in patients with type 2 diabetes inadequately controlled with metformin and an SU. However there were some differences in terms of FPG, hs-CRP, lipids, body-weight change, and AEs.

The dissociation between the diabetes and both Child-Pugh score and in-hospital mortality in cirrhotic patients due to hepatitis B, hepatitis C, or alcoholic.

BACKGROUND: Up to 30% of the cirrhotic patients may clinically be classified as having diabetes. The aims of this retrospective study were to evaluate the prevalence of diabetes, its association with the severity of cirrhosis, and subsequent implication on mortality in a broad population of cirrhotic patients in Taiwan. METHODS: From January 2004 to October 2008, 4,127 cirrhotic patients were reviewed. The latest demographic data were gathered after the latest laboratory measurement in the outpatient or inpatient department. In all, 2,945 patients were included on the basis of the etiology of cirrhosis: hepatitis B, hepatitis C, hepatitis B, and hepatitis C co-infection, or alcoholics. RESULTS: The observed cases of diabetes were significantly higher in cirrhotic patients than general population. Neither the Child-Pugh score (odds ratio = 0.99, p = 0.527) nor the model for end-stage liver disease score (MELD) (odds ratio = 1.00, p = 0.352) was associated with diabetes. The presence of diabetes was dissociated with renal function by means of serum creatinine (ß = -0.01, p = 0.604) or estimated glomerular filtration rate (eGFR) (ß = -0.02, p = 0.233), or in-hospital mortality (odds ratio = 1.08, p = 0.362). CONCLUSION: The prevalence of diabetes was higher in cirrhotic patients in Taiwan. The prevalence of diabetes was dissociated with Child-Pugh or MELD score. The diagnosis of diabetes did not affect the renal function or in-hospital mortality in cirrhotic patients. Since the clinical outcomes of diabetes were different from cirrhotic patients to general population, it is unclear whether the treatment of diabetes and improved glycemic control will benefit cirrhotic patients.

Experience with conservative strategy of uterine artery embolization in the treatment of placenta percreta in the first trimester of pregnancy.

OBJECTIVE: There is little prospective experience in the conservative treatment of placenta percreta during the first trimester in order to preserve uterine fertility. We describe herein our experience with uterine artery embolization (UAE) in the management of placenta percreta at 9 weeks of gestation. CASE REPORT: A 36-year-old woman, gravida 3, para 1, was referred for ultrasonographic evaluation because of suspected molar pregnancy due to persistent vaginal spotting at 9 weeks of gestation. A Grade 3+ lacunar flow pattern with multiple bizarre and large irregular sonolucent spaces were observed. Color Doppler imaging revealed extensive turbulent lacunar blood flow perfusing throughout the whole surrounding uteroplacental tissues and fetus. The patient was informed of the situation and she had a strong desire to avoid surgery. Conservative management with bilateral UAE was performed using polyvinyl alcohol particles to promote involution and shedding of the abnormally adherent placenta. However, an unsatisfactory vessel-occluding effect caused by extensive collateral supply was still detected after repeated UAE. We, therefore, performed hysterectomy, and the patient had an uneventful postoperative course. CONCLUSION: The efficacy and complications of UAE as a therapeutic modality for the conservative management of invasive placentation in the first trimester of pregnancy are not clear, as this is the first report of its kind. However, although UAE had failed in this case, it may still be a useful procedure as a prophylactic measure before surgical intervention, and hysterectomy can also be performed for better control of operative hemorrhage.
