Background: In this recent time, ROS and oxidative stress have been said to play an important role in the pathogenesis of inflamed acne lesions. One example of ROS produced by neutrophil through phagocytosis is H2O2. Nevertheless, there is an enzymatic antioxidant which catalyses H2O2 called catalase. Imbalance of free radicals and antioxidants due to excessive ROS formation promotes the state of oxidative stress and inflammation of the acne lesion.Objective: This study aimed to determine plasma H2O2 and catalase level as a risk factor for acne.Methods: This matched-pair case-control observational analytic study involving 38 patients with acne and 38 patients without acne. Sampling was done using consecutive sampling which fulfils the inclusion and exclusion criteria and followed by matching with age and gender. H2O2 and catalase level measured on both groups. The analysis was done using SPSS.Results: H2O2 mean level in the case and control group, respectively 0.68 ± 0.03 and 0.42 ± 0.04 µmol/ml. High H2O2 level was determined from cut-off point >0.62 µmol/ml. High H2O2 was a statistically significant risk factor for acne vulgaris (p<0.001; 95% CI: 4.59-40.62; OR: 13.67). The mean level of catalase in the case and control group respectively 0.48 ± 0.06 and 0.74 ± 0.07 U/ml. Low catalase level was determined from the cut-off point <0.58 U/ml. Catalase was significant risk factor for acne vulgaris (p<0.001; 95% CI: 5.18-77.21; OR: 20.00).Conclusion: High levels of H2O2 plasma and low levels of catalase plasma is a risk factor of acne vulgaris.

Introduction: Multi-drug resistant Acinetobacter baumannii (MDR-Ab) infections are an important healthcare problem globally. The aim of this study was to evaluate risk factors associated with MDR-Ab infections in hospitalized patients in Turkey. Methodology: A case-control study was performed in a tertiary care 1,303-bed university hospital, among case patients with MDR-Ab infections. The hospital records of case and control patients were retrospectively evaluated over a year. Patients who were hospitalized in the same department and in the same time interval as the case patients, without MDR-Ab infection or colonization, were chosen for control group. Demographic characteristics, Acute Physiology And Chronic Health Evaluation II (APACHE II) scores, comorbid diseases, use of invasive tools and duration of usage, and duration of use of antibiotics were recorded for all patients. Comparisons between case and control groups for possible risk factors were performed. Results: In total, 95 cases and 95 controls were included in the study. Univariate analysis highlighted several variables as risk factors for MDR-Ab infections. Multivariate analysis showed that only antibiotic usage over seven days (OR = 2.38, CI = 1.18-4.83, p = 0.016) was found to be a significant risk factor. When antibiotic treatment patterns in both groups were compared, the use of carbapenems (p = 0.001) and glycopeptide antibiotics (p=0.001) in patient treatment were found significantly higher in the MDR-Ab case group. Conclusion: This study showed us that previous antibiotic use is a significant risk factor for MDR-Ab infections. The use of carbapenems and glycopeptides should be considered as primary risk factors for developing MDR-Ab infection.

Background: In 2015, Indonesia government targeted to eliminate malaria in Java Island. Nevertheless, until now malaria still occurs, including in Samigaluh, Kulon Progo District although many malaria programs has been run. Complexity and dynamic of the population also limited budget may become the reason of malaria combat difficulties. Subsequently, a method to direct the policymaker on how to provide program effectively and efficiently was needed. We examined malaria risk factor using statistical and cluster analysis. Methods: A quantitative study with case-control approach was conducted during Spring 2017 in Samigaluh II Public Health Centre, Indonesia. The structured questioner was used to collect the information from both of case and control which were people who had blood examination regarding malaria diagnosed during JanuaryDecember 2016. Global Positioning System was used to record the geographical position of house participant which was used in cluster analysis. Results: Occupation was recognized as the significant risk factor to malaria. One most likely cluster was detected and translated as the source of transmission because of its fall in malaria hotspot. Conclusion: Satscan be able to detect a spatial cluster of malaria case and a promising method for supporting malaria control.

Background: Physical illness is linked with an increased risk of suicide; however, evidence from China is limited. Aims: To assess the influence of physical illness on risk of suicide among rural residents of China, and to examine the differences in the characteristics of people completing suicide with physical illness from those without physical illness. Method: In all, 200 suicide cases and 200 control subjects, 1:1 pair-matched on sex and age, were included from 25 townships of three randomly selected counties in Shandong Province, China. One informant for each suicide or control subject was interviewed to collect data on the physical health condition and psychological and sociodemographic status. Results: The prevalence of physical illness in suicide cases (63.0%) was significantly higher than that in paired controls (41.0%; χ2 = 19.39, p < .001). Compared with suicide cases without physical illness, people who were physically ill and completed suicide were generally older, less educated, had lower family income, and reported a mental disorder less often. Physical illness denoted a significant risk factor for suicide with an associated odds ratio of 3.23 (95% CI: 1.85–5.62) after adjusted for important covariates. The elevated risk of suicide increased progressively with the number of comorbid illnesses. Cancer, stroke, and a group of illnesses comprising dementia, hemiplegia, and encephalatrophy had a particularly strong effect among the commonly reported diagnoses in this study population. Conclusion: Physical illness is an important risk factor for suicide in rural residents of China. Efforts for suicide prevention are needed and should be integrated with national strategies of health care in rural China.

AbstractPremature atrial complexes (PACs) have been suggested to increase the risk of adverse events. The distribution of PAC burden and its dose–response effects on all-cause mortality and cardiovascular death had not been elucidated clearly. We analyzed 15,893 patients in a medical referral center from July 1st, 2011, to December 31st, 2018. Multivariate regression driven by ln PAC (beats per 24 h plus 1) or quartiles of PAC burden were examined. Older group had higher PAC burden than younger group (p for trend < 0.001), and both genders shared similar PACs distribution. In Cox model, ln PAC remained an independent risk factor for all-cause mortality (hazard ratio (HR) = 1.09 per ln PAC increase, 95% CI = 1.06‒1.12, p < 0.001). PACs were a significant risk factor in cause-specific model (HR = 1.13, 95% CI = 1.05‒1.22, p = 0.001) or sub-distribution model (HR = 1.12, 95% CI = 1.04‒1.21, p = 0.004). In ordinal PAC model, 4th quartile group had significantly higher risk of all-cause mortality than those in 1st quartile group (HR = 1.47, 95% CI = 1.13‒1.94, p = 0.005), but no difference in cardiovascular death were found in competing risk analysis. In subgroup analysis, the risk of high PAC burden was consistently higher than in low-burden group across pre-specified subgroups. In conclusion, PAC burden has a dose response effect on all-cause mortality and cardiovascular death.

Abstract Objective: To determine whether electronically available comorbidities and laboratory values on admission are risk factors for hospital-onset Clostridioides difficile infection (HO-CDI) across multiple institutions and whether they could be used to improve risk adjustment. Patients: All patients at least 18 years of age admitted to 3 hospitals in Maryland between January 1, 2016, and January 1, 2018. Methods: Comorbid conditions were assigned using the Elixhauser comorbidity index. Multivariable log-binomial regression was conducted for each hospital using significant covariates (P < .10) in a bivariate analysis. Standardized infection ratios (SIRs) were computed using current Centers for Disease Control and Prevention (CDC) risk adjustment methodology and with the addition of Elixhauser score and individual comorbidities. Results: At hospital 1, 314 of 48,057 patient admissions (0.65%) had a HO-CDI; 41 of 8,791 patient admissions (0.47%) at community hospital 2 had a HO-CDI; and 75 of 29,211 patient admissions (0.26%) at community hospital 3 had a HO-CDI. In multivariable regression, Elixhauser score was a significant risk factor for HO-CDI at all hospitals when controlling for age, antibiotic use, and antacid use. Abnormal leukocyte level at hospital admission was a significant risk factor at hospital 1 and hospital 2. When Elixhauser score was included in the risk adjustment model, it was statistically significant (P < .01). Compared with the current CDC SIR methodology, the SIR of hospital 1 decreased by 2%, whereas the SIRs of hospitals 2 and 3 increased by 2% and 6%, respectively, but the rankings did not change. Conclusions: Electronically available patient comorbidities are important risk factors for HO-CDI and may improve risk-adjustment methodology.

The current outbreak caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), termed coronavirus disease 2019 (COVID-19), has generated a notable challenge for diabetic patients. Overall, people with diabetes have a higher risk of developing different infectious diseases and demonstrate increased mortality. Type 2 diabetes mellitus (T2DM) is a significant risk factor for COVID-19 progression and its severity, poor prognosis, and increased mortality. How diabetes contributes to COVID-19 severity is unclear; however, it may be correlated with the effects of hyperglycemia on systemic inflammatory responses and immune system dysfunction. Using the envelope spike glycoprotein SARS-CoV-2, COVID-19 binds to angiotensin-converting enzyme 2 (ACE2) receptors, a key protein expressed in metabolic organs and tissues such as pancreatic islets. Therefore, it has been suggested that diabetic patients are more susceptible to severe SARS-CoV-2 infections, as glucose metabolism impairments complicate the pathophysiology of COVID-19 disease in these patients. In this review, we provide insight into the COVID-19 disease complications relevant to diabetes and try to focus on the present data and growing concepts surrounding SARS-CoV-2 infections in T2DM patients.
