Brazil has the second highest number of deaths due to COVID-19. Obesity has been associated with an important role in disease development and a worse prognosis. We aimed to explore epidemiological data from Brazil, discussing the potential relationships between obesity and COVID-19 severity in this country. We used a public database made available by the Ministry of Health of Brazil (182700 patients diagnosed with COVID-19). Descriptive statistics were used to characterize our database. Continuous data were expressed as median and analyzed by the nonparametric tests Mann–Whitney or one-sample Wilcoxon. The frequencies of categorical variables have been analyzed by chi-square tests of independence or goodness-of-fit. Among the number of deaths, 74% of patients were 60 years of age or older. Patients with obesity who died of COVID-19 were younger (59 years (IQR = 23)) than those without obesity (71 years (IQR = 20), P < 0.001 , and η2 = 0.0424). Women with obesity who died of COVID-19 were older than men (55 years (IQR = 25) vs. 50 (IQR = 22), P < 0.001 , and η2 = 0.0263). Furthermore, obesity increases the chances of needing intensive care unit (OR: 1.783, CI: 95%, and P < 0.001 ), needing ventilatory support (OR: 1.537, CI: 95%, and P < 0.001 and OR: 2.302, CI: 95%, and P < 0.001 , for noninvasive and invasive, respectively), and death (OR: 1.411, CI: 95%, and P < 0.001 ) of patients hospitalized with COVID-19. Our analysis supports obesity as a significant risk factor for the development of more severe forms of COVID-19. The present study can direct a more effective prevention campaign and appropriate management of subjects with obesity.

The Impact

Abstract Background Pneumonia is a significant cause of morbidity and mortality, with increasing interest in the detection and clinical significance of co-infection. However, the impact of methodology to obtain lower respiratory samples along with the utility of various microbiological diagnostic testing remains unclear. Methods A single-center retrospective analysis was performed on bronchoalveolar lavage (BAL) samples obtained from mechanically ventilated adults treated in critical care units from August 2012 to December 2017. BAL methodology (bronchoscopic vs blinded), microbiological diagnostic testing, and outcomes measures were obtained. Associations between categorical variables were assessed using Chi-Square or Fisher’s exact tests. Kruskal Wallace tests analyzed differences in distributions of measures between categories based on number of organism types detected. SAS software version 9.4 (SAS Institute Inc., Cary, NC). Results Analysis of the 803 samples that met inclusion criteria found a significant linear association between mortality and number of organism types detected by BAL, with 30 day mortality rates of 43.0%, 47.8%, and 58.3% among those with zero, one, and two or more organisms respectively (p = 0.003). Comparing BALs with at least one organism isolated, the detection of viruses specifically was associated with increased mortality, with the presence and absence of viral organisms corresponding to 56.3% and 46.5% mortality at thirty days (p = 0.03). No association was found between mortality and isolation of acid-fast bacilli, bacteria, or fungi. Co-infection was detected more frequently among bronchoscopic BALs than blinded BALs (26.3% vs 8.6%, p &lt; 0.0001), with more viruses detected bronchoscopic BALs (41.9% vs 13.1%, p &lt; 0.0001), and more bacteria in blinded BALs (41.8% vs 33.0%, p = 0.01). 30 Day Mortality vs Isolation of Specific Organism Types from BAL Number of Organism Types Isolated from BAL Compared to BAL Methodology BAL Methodology vs Isolation of Specific Organism Types Conclusion Co-infection in mechanically ventilated adult patients with pneumonia appears to be a significant risk factor for mortality, with the detection of viral organisms potentially playing an independent role. Within this population, bronchoscopic BALs may have a valuable diagnostic and prognostic methodology. Disclosures All Authors: No reported disclosures

Abstract Purpose:This study evaluated the incidence rate and risk factors for developing myopia in elementary school students in Chiayi, Taiwan.Methods:This prospective cohort study comprised 1816 students without myopia (grades 1 to 5 in Chiayi County). The students underwent a noncycloplegic ocular alignment examinations using an autorefractometer and completed a questionnaires at baseline and at a 1-year follow-up. A univariate logistic regression was used to assess the effects of the categorical variables on new cases of myopia. A multinomial logistic regression was then conducted. A chi-squared test was used to compare new cases of myopia in terms of ocular alignment. A Cox hazard ratio model was then used to validate factors associated with changes in ocular alignment. A P value of <.05 was considered significant.Results: In 370 participants with new cases of myopia out of 1816 participants, a spherical error of −1.51 ± 0.6 diopters was noted at follow-up. The baseline ocular alignment was not a significant risk factor for developing myopia (exophoria vs orthophoria: OR 1.26, 95% CI 0.97-1.62; other vs. orthophoria: OR 1.15, 95% CI 0.73-1.82). However, new cases of myopia (HR 1.36, 95% CI 1.14-1.61), and baseline ocular alignment (exophoria vs orthophoria: HR 3.76, 95% CI 3.20-4.42; other vs orthophoria: HR 3.02, 95% CI 2.05-4.45) were associated with exophoria at follow-up.Conclusions: This study provided epidemiological data on the incidence of myopia in elementary school students in Chiayi, Taiwan. It also demonstrated that physiological exophoria does not predispose patients to developing myopia.

Abstract Teenagers are important carriers of Neisseria meningitidis, which is a leading cause of invasive meningococcal disease. In China, the carriage rate and risk factors among teenagers are unclear. The present study presents a retrospective analysis of epidemiological data for N. meningitidis carriage from 2013 to 2017 in Suizhou city, China. The carriage rates were 3.26%, 2.22%, 3.33%, 3.53% and 9.88% for 2013, 2014, 2015, 2016 and 2017, respectively. From 2014 to 2017, the carriage rate in the 15- to 19-year-old age group (teenagers) was the highest and significantly higher than that in remain age groups. Subsequently, a larger scale survey (December 2017) for carriage rate and relative risk factors (population density, time spent in the classroom, gender and antibiotics use) were investigated on the teenagers (15- to 19-year-old age) at the same school. The carriage rate was still high at 33.48% (223/663) and varied greatly from 6.56% to 52.94% in a different class. Population density of the classroom was found to be a significant risk factor for carriage, and 1.4 persons/m2 is recommended as the maximum classroom density. Further, higher male gender ratio and more time spent in the classroom were also significantly associated with higher carriage. Finally, antibiotic use was associated with a significantly lower carriage rate. All the results imply that attention should be paid to the teenagers and various measures can be taken to reduce the N. meningitidis carriage, to prevent and control the outbreak of IMD.

Background Wilms tumor is the most common renal malignancy in children (95%) and one of the leading causes of death in children, with high mortality rates in developing countries. Identifying risk factors for mortality is important in order to provide early intervention to improve cure rates.Objective To identify risk factors for mortality in children with Wilms tumor.Methods We performed a case-control study of children (0-18 years of age) with Wilms tumor admitted to Dr. Sardjito Hospital between 2005 and 2012. The case group consisted of children who died of Wilms tumor, whereas the control group were children who survived. Data were collected from medical records. Statistical analyses using Chi-square and logistic regression tests were done to determine odds ratios and 95% CI of the potential risk factors for mortality from Wilms tumor.Results Thirty-five children with Wilms tumor were admitted to Dr. Sardjito Hospital during the study period. Nine (26%) children died and 26 survived. Stage ≥III was a significant risk factor for mortality in chidren with Wilms tumor (OR 62.8; 95%CI 5.6 to 70.5). Age ≥2 years (OR 1.4; 95%CI 0.1 to 14.3) and male sex (OR 1.2; 95%CI 0.1 to 10.8) were not significant risk factors for mortality.Conclusion Stage ≥III is a risk factor for mortality in children with Wilms tumor.

Abstract Background and Aims: Respiratory complications are of major concern after intracranial procedures. The objective of the study was to assess the incidence of respiratory complications in the initial 72 hours after elective craniotomies and to identify the associated risk factors. Materials and Methods: Patients undergoing elective craniotomies were studied prospectively. Information pertinent to history, physical examinations, investigation reports, perioperative events and outcome at discharge of the patients were recorded. Occurrence of any sign or symptom of respiratory system, need for reintubation/increased ventilatory support within 72 hours of surgery were considered as post-operative respiratory complication. Relationships of numerical variables and categorical variables with post-operative respiratory complications (PRCs) were assessed via T test and Chi-square (or Fisher’s exact). Multivariate analysis using multiple logistic regression was performed for finding independent risk factors for respiratory complications. Results: Out of 961 patients, 137 (14.3%) patients developed PRC within 72 hours of surgery. Ninety-nine (10.3%) patients developed purulent tracheobronchitis. The patients who had PRC had longer hospital stays and poor Glasgow Outcome Scale at hospital discharge. The variables found as independent risk factors were tachycardia, blood transfusion in the intraoperative period and Glasgow Coma Scale (GCS) deterioration, hypokalemia and fever in the post-operative period. Conclusions: Respiratory complications within first 72 hours of elective craniotomies were common and were associated with prolonged hospital stay and poor neurological outcome. The variables which were found as independent risk factors were tachycardia, blood transfusion in the intraoperative period and GCS deterioration, hypokalemia and fever in the post-operative period.

Abstract Bullying is a common and significant risk factor for mental and physical health problems. The aim of the outlined study was to evaluate the German version of the Olweus Bullying Prevention Program (OBPP) and to investigate potential moderators of its effectiveness. 23 schools started with the implementation and all students were invited to complete the Olweus Bullying Questionnaire annually. For our analyses, the data from grades 5 to 9 were used (t0: n = 5759; t1: n = 5416; t2: n = 4894). 16 out of the 23 schools completed the 18-months implementation period. The effectiveness of the program statistically depended on its complete implementation (χ2(2) = 7.62, p = 0.022). In the group of non-completers, the prevalence of victimization did not change during the observation period of 2 years (χ2(2) = 4.64, p = 0.099). In the group of the completer schools, a significant decrease in bullying between t0 and t1 was found for victims (t0: 9.14%; t1: 6.87%; OR = 0.74; 95% CI 0.62–0.88; p = 0.001) and perpetrators (t0: 6.16%; t1: 4.42%; OR = 0.70; 95% CI 0.55–0.89; p = 0.004). After 24 months (t2), this decrease could be retained (victims: t2: 6.83%; OR = 0.73; 95%CI = 0.61–0.88; p = 0.001; perpetrators: t2: 4.63%; OR = 0.72; 95% CI 0.57–0.92; p = 0.009). Furthermore, we found the following moderators of program effectiveness in the completer schools: (1) gender (with a stronger decrease among victimized girls; p = 0.004) and (2) school grade (with a stronger decrease of victimization among grades 5–7; p = 0.028). The German version of the OBPP significantly reduced the bullying prevalence in the completer schools. Effective prevention needs time and resources: fulfilling the 18-months implementation period was the basis for positive results.

INTRODUCTION. Clostridium difficile associated colitis became over last years a worldwide medical issue. It involves patients of the Polish hospitals too. The aim of the study was the analysis of CDAD incidence and the course of infection in Gastroenterology Ward of Regional Specialist Hospital of Zgierz, 2012-2015. MATERIAL AND METHODS. Retrospective analysis of the medical documentation of 79 patients with CDAD was performed. Demographic and epidemiological data and the clinical course of infection were analyzed. RESULTS. The study group comprised of women in 59,5% and men in 40,5%. The patients’ average age was 70,5 years. The average hospitalization period was 10,3 days. CDAD infection seasonality was proved, with statistically significant peak in springtime. 73% of patients were previously hospitalized and 85% - had co-morbidities. 76% of patients underwent antibiotherapy, whilst 29% - used PPI prior to CDAD diagnosis. 50,6% of patients had severe CDAD diagnosed. The recurrence reached 14%. In 19% of patients CDAD resulted in death. DISCUSSION. The results of the study confirm increase of the incidence of the patients with CDAD in Gastroenterology Ward over 4-years’ observation. The prevalence was higher among 65+ patients, after prior hospitalization and antibiotherapy. The co-morbidities was a significant risk factor, especially common in severe cases. CONCLUSION. The results we obtained confirm substantial importance of Clostridium difficile infection leading to antibiotherapy- associated diarrhea among adults, causing prolonged hospitalization, increased prevalence and mortality of patients. Getting to know and minimizing the risk factors will prevent the future outbreak of the disease.

AbstractBackgroundKlebsiella pneumoniae is an opportunistic pathogen and a leading cause of hospital-associated (HA) infections. Patients in intensive care units (ICUs) are particularly at risk, and outbreaks are frequently reported in ICUs. K. pneumoniae is also part of the healthy human microbiome, providing a potential reservoir for HA infection. However, the frequency of K. pneumoniae gut colonization and its contribution to HA infections are not well characterized.MethodsWe conducted one-year prospective cohort study of ICU patients. Participants (n=498) were screened for rectal and throat carriage of K. pneumoniae shortly after admission, and clinical information was extracted from hospital records.K. pneumoniae isolated from screening swabs and clinical diagnostic samples were characterized using whole genome sequencing. Genomic and epidemiological data were combined to identify likely transmission events.Results and ConclusionsK. pneumoniae carriage frequencies were estimated at 6% (95% CI, 3%-8%) amongst ICU patients admitted direct from the community, and 19% (95% CI, 14% – 51%) amongst those who had recent contact with healthcare. Gut colonisation on admission was significantly associated with subsequent K. pneumoniae infection (infection risk 16% vs 3%, OR=6.9, p<0.001), and genome data indicated a match between carriage and infection isolates in most patients. Five likely transmission chains were identified, resulting in six infections (12% of K. pneumoniae infections in ICU). In contrast, 49% of K. pneumoniae infections were caused by a strain that was unique to the patient, and 48% of patients with K. pneumoniae infections who participated in screening were positive for prior colonisation. These data confirm K. pneumoniae colonisation is a significant risk factor for subsequent infection in ICU, and indicate that half of all K. pneumoniae infections result from patients’ own microbiota. Screening for colonisation on admission could limit risk of infection in the colonised patient and others.

Background: Diabetic foot ulcers (DFU) are debilitating to the patients and significantly impair their quality of life. DFU associated with infection have the worst outcomes and may lead to amputations if timely intervention is not done. In the present study, aim was to identify the association between the type of organism isolated and the rates of amputations in diabetic foot ulcers.Methods: We retrospectively studied 50 diabetic foot ulcers from January 2017 to June 2017, who were in-patients in a single unit of surgery department in King George Hospital, Visakhapatnam. Baseline clinical examination was done. Parameters such as age, sex, duration, diabetic status and its treatment, organisms isolated, various treatment options for ulcers and the outcomes were studies.Results: Males were the predominant study subjects (M: F=32:18). The age of presentation was 18-65 years with an average of 46 years. Gram negative organisms were the frequent microbial isolates, all being mono-microbial infections. It was dominated by E. coli (17), Pseudomonas (12) and Klebsiella (11). Above-knee amputation was done in one patient and below-knee amputations in three patients. Total mortality in our study was 5. After applying the chi-square test, it was found that there is no significant association between the type of organism and the rate of amputations in our study.Conclusions: Diabetes is a significant risk factor for ulceration in the extremities, which possesses considerable mortality and morbidity. Early intervention, control of diabetes and compliance of the patient treatment are all necessary to reduce the rates of amputations and mortality in patients with diabetic foot ulcers.

AbstractTuberculous empyema (TE) is associated with high mortality and morbidity. In the retrospective cohort study, we aimed to find risk factors for TE among pleural tuberculosis (TB) patients. Between July 2011 and September 2015, all culture-confirmed pleural TB patients (474 cases) were enrolled in our study. Empyema was defined as grossly purulent pleural fluid. Demographic and epidemiological data were collected for further analysis. Multivariate logistic regression analysis was used to evaluate risk factors of TE in pleural TB, age–adjusted odds ratio (OR) and 95% confidence interval (CI) were calculated to show the risk. The mean age was 35.7 ± 18.1 years old, males comprised 79.1% of the participants (375 cases). Forty-seven patients (9.9%) were multidrug-resistant TB (MDR-TB), 29 (6.1%) had retreatment TB, 26 (5.5%) had diabetes mellitus. The percentage of empyema patients was 8.9% (42 cases). Multivariate analysis revealed that male (adjusted OR = 4.431, 95% CI: 1.411, 13.919), pleural adenosine deaminase (ADA, >88 U/L) (adjusted OR = 3.367, 95% CI: 1.533, 7.395) and white blood cell (WBC, >9.52 109/L) (adjusted OR = 5.763, 95% CI: 2.473, 13.431) were significant risk factors for empyema in pleural TB, while pulmonary TB (adjusted OR = 0.155, 95% CI: 0.072, 0.336) was the protective factor for the patients. TE remains a serious threat to public health in China. Male sex is a significant risk factor for TE while the presence of pulmonary TB is protective, and high levels of pleural ADA and WBC count could aid in early diagnosis of TE. This finding would help towards reducing the mortality and morbidity associated with TE.
