BACKGROUND Type 1 diabetes(T1D)contributes to altered lipid profiles and increases the risk of cardiovascular disease(CVD).Youth with T1D may have additional CVD risk factors within the first decade of diagnosis.AIM To examine risk factors for dyslipidemia in young subjects with T1D.METHODS Longitudinal and cross-sectional retrospective study of 170 young subjects with T1D(86 males;baseline mean age 12.2±5.6 years and hemoglobin A1c 8.4%±1.4%)were followed in a single tertiary diabetes center for a median duration of 15 years.Predictors for outcomes of lipid profiles at last visit(total cholesterol[TC],triglycerides[TGs],low-density lipoprotein-cholesterol[LDL-c],and highdensity lipoprotein-cholesterol[HDL-c])were analyzed by stepwise linear regression models.RESULTS At baseline,79.5%of the patients had at least one additional CVD risk factor(borderline dyslipidemia/dyslipidemia[37.5%],pre-hypertension/hypertension[27.6%],and overweight/obesity[16.5%])and 41.6%had multiple(≥2)CVD risk factors.A positive family history of at least one CVD risk factor in a first-degree relative was reported in 54.1%of the cohort.Predictors of elevated TC:family history of CVD(β[SE]=23.1[8.3],P=0.006);of elevated LDL-c:baseline diastolic blood pressure(DBP)(β[SE]=11.4[4.7],P=0.003)and family history of CVD(β[SE]=20.7[6.8],P=0.017);of elevated TGs:baseline DBP(β[SE]=23.8[9.1],P=0.010)and family history of CVD(β[SE]=31.0[13.1],P=0.020);and of low HDL-c levels:baseline DBP(β[SE]=4.8[2.1],P=0.022]).CONCLUSION Our findings suggest that elevated lipid profiles are associated with DBP and a positive family history of CVD.It is of utmost importance to prevent and control modifiable risk factors such as these,as early as childhood,given that inadequate glycemic control and elevation in blood pressure intensify the risk of dyslipidemia. 展开更多

However traveling abroad and staying in an unfamiliar environment with inadequate medical infrastructure exposes volunteers to a wide range of health risks. The aim of this study was to clarify the relationships among disease knowledge and symptoms, disease risk perception, and self-management skills. <strong>Methods:</strong> This was a questionnaire survey of 189 Japanese who were preparing to volunteer abroad. A factor analysis was conducted on 13 items (six general risk events and seven major diseases) of risk perception. Correlation analysis was performed between the identified risk perception factors and disease knowledge and symptoms. Risk perception scores by factors from the seven disease items were compared between the Self-management Score (SMS) group and disease knowledge and risk of symptoms group, using T-tests. St. Luke’s International University Ethics Committee (19-A092) approved this study. <strong>Results:</strong> Many participants expected to suffer from digestive diseases (69.3%) and dermatitis (55%) in the field. On the other hand, few expected high risk of malaria (26.5%) or dengue fever (36%). Factor analysis yielded robust factor loadings creating a “Dread” and an “Unknown” factor accounting for 62.2% of total variance. Strong correlation was not found between SMS and disease risk perception. A weak negative correlation was observed in dengue fever, digestive disorders, and dermatitis (r = <span style="white-space:nowrap;">&minus;</span>0.20 to <span style="white-space:nowrap;">&minus;</span>0.25, p < 0.001) on the “Unknown” factor. A high SMS score was associated with a lower “Unknown” factor score for malaria, diarrhea, dermatitis, and dental disorders. In addition, higher disease knowledge was significantly associated with higher “Dread” factor score for dental disorders. <strong>Conclusions: </strong>Self-management skills and disease knowledge will enable higher risk awareness of common diseases and high lethality diseases. 展开更多

Especially the use of split and living donor transplants even for infants has led to new challenges in pre- and post-operative care. Systemic inflammatory response syndromes (SIRS, sepsis) as well-known complications after LT have not yet been systematically examined in the pediatric population. <strong>Methods:</strong> We analyzed clinical data of 39 pediatric liver transplant recipients regarding potential risk factors for post-transplant SIRS and sepsis. Secondly, the prognostic impact of SIRS and sepsis on post-transplant clinical course, patient and transplant-survival has been analyzed. <strong>Results:</strong> 64% of patients developed either SIRS (n = 16, 41%) or sepsis (n = 9, 23%) within 30 days after transplantation. No pre-transplant risk factors for increased susceptibility for SIRS or sepsis could be identified. Secondary closure of the abdomen (p = 0.045) and secondary biliary reconstruction (p = 0.043) were associated with a higher incidence of sepsis and were associated with significantly prolonged mechanical ventilation times in the presence of sepsis (p = 0.001). Patients with sepsis, but not SIRS, stayed significantly longer on PICU (p = 0.021) and suffered from higher mortality (n = 3 versus 0;p = 0.0006). All deaths within 30 days of transplantation were due to septic multiorgan failure. Neither early SIRS nor sepsis were associated with loss of transplant function. <strong>Conclusions:</strong> SIRS and sepsis are frequent events after pediatric liver transplantation. Sepsis increased length of PICU-stay and mortality significantly and prolonged duration of mechanical ventilation. Secondary biliary reconstruction and closure of the abdomen could be identified as potential risk factors for sepsis. </div> 展开更多

The objective of this study was to describe the management of these lesions, and to identify signifiant risk factors associated with mortality in patients with a PCCW. <strong>Methods.</strong> It was a transversal, descriptive and analytical study performed in Departmental Teaching Hospital of Borgou and Alibori in Benin. From January 1, 2015 to June 30, 2020, patients with a PCCW were retained. Risk factors of mortality and morbidity associated to etiological, clinical and surgical parameters were assessed using the chi-square test. p value < 0.05 was considered to be statistically significant. <strong>Results.</strong> During the study period, 1267 cases of traumatic brain injuries (TBI) were admitted. Of these patients, 77 (6.1%) cases of PCCW were retained. These patients were divided into 66 (85.7%) male and 11 (14.3%) female. The mean age of the patients was 22.6 ± 14.8 years (range from 2 years to 70 years). The circumstances of occurrence were a traffic accident in 42 (54.5%) cases, an assault in 33 cases (42.9%) and a fall 2 (2.6%). The PCCW was unilateral in 71 cases (92.2%). A brain CT-scan was performed in 60 (77.9%) patients. Surgery was performed in 69 (89.6%) patients. Post-operative outcomes were simple in 59 (85.5%) cases. GCS, pupillary abnormalities, motor deficit were a statistically significant risk factor associated with death or sequels (p < 0.0001).<strong> Conclusion.</strong> The identification of risk factors of mortality or sequels is a major step for an efficient management of PCCWs and a reduction of morbidity and mortality. Whatever strategies are adopted, prevention must remain a priority. 展开更多

Despite not included in the traditional risk scores before surgery, liver cirrhosis, especially in advanced stages, has always influenced strongly final outcome both on short and midterm in patients undergoing cardiac surgery. Growing incidence of non-alcoholic fatty liver disease interlinked with metabolic syndrome and significant advancements in medical therapy have actually increased the likelihood of cardiac surgery in cirrhotic patients. To date, Child-Pugh and MELD scores have been commonly used to predict mortality and postoperative hepatic decompensation, but on the other hand, both traditional risk scores show some limitations for evaluation of hepatopathic patients undergoing specifically cardiac surgery. In this context, a specific Heart-Liver score hasn’t been developed yet in the attempt to outline a patient profile able to face surgery, therefore addressing us to adopt the best strategy possible for each case. If CP class A or low MELD score (<11) patients tolerate cardiac surgery with a mild increase in mortality and morbidity, currently state of art recommends particular caution towards surgery idea in presence of advanced hepatic disease. As far as cardiac surgery represents the unique therapeutic strategy in several life-threatening cases, anyway surgical correction of cardiac pathology won’t guarantee an increased life expectancy in accordance with the persistent liver dysfunction. Hereby, this paper will focus on preoperative parameters that should be considered in the future realization of a Heart-Liver prognostic score for overcoming limitations and difficulties related to the impact of liver disease on final clinical outcome. 展开更多

Healthcare-associated infections (HCAIs) remain a major public health concern. The aim of this study was to characterize potential pathogenic bacteria isolated in high-risk infectious services at the University Hospital Center of Suru-Léré in Benin. A cross-sectional, descriptive study was carried out on 215 samples with 8 air samples, 20 hand samples and 187 samples of medical-technical material. Genes for resistance to <i>β</i>-lactam antibiotics (blaTEM, blaSHV, blaCTX-M and blaOXA-1) were sought. The data were processed and analyzed using EPI Info version 3.5.4 software. A total of 10 bacterial species were identified. Of the 319 bacterial strains identified, <i>Staphylococcus saprophyticus</i>, <i>Staphylococcus aureus</i> and <i>Enterococcus faecalis</i> were predominant at 20.06%, 17.87% and 11.28% respectively. Antibiotic susceptibility showed that the majority of bacterial strains were multidrug-resistant. Of the 4 resistance genes sought, only the blaTEM and blaSHV genes were found. The poor microbiological quality observed in high-risk infectious services could be a risk factor for healthcare-associated infections. It is therefore useful to implement preventive measures in order to prevent or reduce the risk of healthcare-associated infections. 展开更多

Personal credit risk assessment is an important part of the development of financial enterprises. Big data credit investigation is an inevitable trend of personal credit risk assessment, but some data are missing and the amount of data is small, so it is difficult to train. At the same time, for different financial platforms, we need to use different models to train according to the characteristics of the current samples, which is time-consuming. <span style="font-family:Verdana;">In view of</span><span style="font-family:Verdana;"> these two problems, this paper uses the idea of transfer learning to build a transferable personal credit risk model based on Instance-based Transfer Learning (Instance-based TL). The model balances the weight of the samples in the source domain, and migrates the existing large dataset samples to the target domain of small samples, and finds out the commonness between them. At the same time, we have done a lot of experiments on the selection of base learners, including traditional machine learning algorithms and ensemble learning algorithms, such as decision tree, logistic regression, </span><span style="font-family:Verdana;">xgboost</span> <span style="font-family:Verdana;">and</span><span style="font-family:Verdana;"> so on. The datasets are from P2P platform and bank, the results show that the AUC value of Instance-based TL is 24% higher than that of the traditional machine learning model, which fully proves that the model in this paper has good application value. The model’s evaluation uses AUC, prediction, recall, F1. These criteria prove that this model has good application value from many aspects. At present, we are trying to apply this model to more fields to improve the robustness and applicability of the model;on the other hand, we are trying to do more in-depth research on domain adaptation to enrich the model.</span> 展开更多

This article will highlight the research completed in the area of organizational decision-making on cybersecurity spend. In leveraging the review of additional studies, this research utilizes a regression framework and case study methodology to demonstrate that effective risk-based decisions are necessary when implementing cybersecurity controls. Through regression analysis, the effectiveness of current implemented cybersecurity measures in organizations </span><span style="font-size:12px;font-family:Verdana;">is</span><span style="font-size:12px;font-family:Verdana;"> explored when connecting a dependent variable with several independent variables. The focus of this article is on the strategic decisions made by organizations when implementing cybersecurity measures. This research belongs to the area of risk management, and various models within the field of 1) information security</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 2) strategic management</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> and 3) organizational decision-making to determine optimum spending on cybersecurity measures for risk taking organizations.

The case study methodology provides an in-depth view of a risk-taking organization’s risk mitigation strategy within the bounds of the educational environment focusing on five areas identified within a digital cyber risk model: 1) technology landscape and application portfolio</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 2) data centric focus</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 3) risk management practices</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 4) cost-benefit analysis for cybersecurity measures</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> and 5) strategic development. The outcome of this research provides greater insight into how an organization makes decisions when implementing cybersecurity controls. This research shows that most organizations are diligently implementing security measures to effectively monitor and detect cyber security attacks</span><span style="font-size:12px;font-family:Verdana;">,</span><span style="font-size:12px;font-family:Verdana;"> specifically showing that risk taking organizations implemented cybersecurity measures to meet compliance and audit obligations with an annual spend of $3.18 million. It also indicated that 23.6% of risk-taking organizations incurred more than 6 cybersecurity breaches with an average dollar loss of $3.5 million. In addition, the impact of a cybersecurity breach on risk taking organizations is as follows: 1) data loss</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 2) brand/reputational impact</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 3) financial loss fines</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> 4) increase oversight by regulators/internal audit</span><span style="font-size:12px;font-family:Verdana;">;</span><span style="font-size:12px;font-family:Verdana;"> and 5) customer/client impact. The implication this research has on practice is extensive, as it focuses on a broad range of areas to include risk, funding and type and impact of cyber security breaches encountered. The survey study clearly demonstrated the need to develop and utilize a digital cybersecurity risk management framework to integrate current industry frameworks within the risk management practice to include continuous compliance management. This type of framework would provide a balanced approach to managing the gap between a risk-taking organization and a risk averse organization when implementing cybersecurity measures. 展开更多

BACKGROUND Melatonin is reported to be related to diabetes mellitus(DM)risk;however,the effect of melatonin on diabetic retinopathy(DR)risk remains unclear.AIM The aim of this study was to determine the effect of melatonin on DR risk.METHODS A hospital-based case-control study was conducted from January 2020 to June 2020.DR was assessed using the Diabetic Retinopathy preferred practice pattern(PPP)-updated 2019 criteria.The participants were divided into the DM cases without DR(NDR)group,non-proliferative DR(NPDR)group and proliferative DR(PDR)group.Plasma melatonin concentration was detected with the enzymelinked immunosorbent assay kit.The relationship between plasma melatonin concentration and DR risk as well as severity was assessed.RESULTS It was found that plasma melatonin was 72.83±16.25,60.38±13.43,44.48±10.30 and 44.69±8.95 pg/mL in healthy controls,NDR group,NPDR and PDR group,respectively.In addition,it was found that plasma melatonin could be used as a potential diagnostic biomarker for DR(AUC=0.893,P<0.001).There was a significant positive relationship between total bilirubin and melatonin content(P<0.001)based on the correlation assay.Significant associations between total bilirubin and melatonin content were also detected in the NPDR(R2=0.360,P<0.001)and PDR(R2=0.183,P<0.001)groups.CONCLUSION The data obtained in this study demonstrated that plasma melatonin concentration was decreased in DR cases and could be used as a sensitive and specific marker for the diagnosis of DR.A significant positive relationship between total bilirubin and melatonin was detected.More related studies are required to understand the role of melatonin in DR. 展开更多

BACKGROUND In rare instances,primary liver cancer can be associated with intraocular metastasis(IOM).AIM To investigate the correlation between a diverse range of clinical characteristics and IOM in diabetic patients with primary liver cancer,and to determine potential risk factors in predicting IOM.METHODS We recruited a total of 722 diabetic patients with primary liver cancer.The differences between the IOM and non-intraocular metastasis(NIOM)groups in these patients were assessed using the chi-squared test and Student’s t-test.Binary logistic regression analysis was subsequently used to determine risk factors.Finally,the diagnostic value of IOM in this cohort with primary liver cancer was analyzed by receiver operating characteristic(ROC)curve analysis.RESULTS In all,13 patients had IOM.There were no remarkable intergroup differences with respect to age,sex,histopathological sub-types,or blood biochemical parameters.However,the IOM group had significantly higher alpha-fetoprotein(AFP)and cancer antigen 125(CA125)values than the NIOM group.Binary logistic regression identified AFP and CA125 to be significant risk factors for IOM in diabetic patients with primary liver cancer.ROC curve analysis showed that the area under the curve values for AFP and CA125 were 0.727 and 0.796,with the cut-off values of 994.20 ng/mL and 120.23 U/mL,respectively.The sensitivity and specicity for AFP were 92.3%and 59.9%,while those for CA125 were 84.6%and 70.1%,respectively.CONCLUSION Elevated AFP and CA125 represent significant risk factors for IOM in diabetic patients with primary liver cancer. 展开更多

Antibiotics released into the environment through anthropogenic activities exert selective pressure,driving bacteria towards increasing antimicrobial resistance.The prevalence of antibiotics and the ecological risks posed in the riverine estuarine of Larut River and Sangga Besar River,which included wastewater effl uents from hospital,zoo,and poultry slaughterhouse sources were investigated.Solid phase extraction(SPE)followed by high-performance liquid chromatography tandem mass chromatography(HPLC-MS/MS)were used to extract and quantify the antibiotic residues from 22 antibiotics belonging to six major antibiotic classes(sulfonamide,macrolide,fl uoroquinolone,phenicol,trimethoprim,and tetracycline).Sixteen antibiotic residues were detected with concentrations ranging from limit of detection(LOD)to 1262.3 ng/L.Fluoroquinolones and macrolides were the most frequently detected compounds.Erythromycin,clarithromycin,and ofl oxacin detected in hospital and zoo effl uents posed a high risk to algae while tetracycline had low to medium ecological risks toward all the relevant organisms from aquatic environments(algae,invertebrate Daphnia magna,and fi sh). 展开更多
