IntroductionThere were almost 1 million deaths in children aged between 5 and 14 years in 2017, and pneumonia accounted for 11%. However, there are no validated guidelines for pneumonia management in older children and data to support their development are limited. We sought to understand risk factors for mortality among children aged 5–14 years hospitalised with pneumonia in district-level health facilities in Kenya.MethodsWe did a retrospective cohort study using data collected from an established clinical information network of 13 hospitals. We reviewed records for children aged 5–14 years admitted with pneumonia between 1 March 2014 and 28 February 2018. Individual clinical signs were examined for association with inpatient mortality using logistic regression. We used existing WHO criteria (intended for under 5s) to define levels of severity and examined their performance in identifying those at increased risk of death.Results1832 children were diagnosed with pneumonia and 145 (7.9%) died. Severe pallor was strongly associated with mortality (adjusted OR (aOR) 8.06, 95% CI 4.72 to 13.75) as were reduced consciousness, mild/moderate pallor, central cyanosis and older age (>9 years) (aOR >2). Comorbidities HIV and severe acute malnutrition were also associated with death (aOR 2.31, 95% CI 1.39 to 3.84 and aOR 1.89, 95% CI 1.12 to 3.21, respectively). The presence of clinical characteristics used by WHO to define severe pneumonia was associated with death in univariate analysis (OR 2.69). However, this combination of clinical characteristics was poor in discriminating those at risk of death (sensitivity: 0.56, specificity: 0.68, and area under the curve: 0.62).ConclusionChildren >5 years have high inpatient pneumonia mortality. These findings also suggest that the WHO criteria for classification of severity for children under 5 years do not appear to be a valid tool for risk assessment in this older age group, indicating the urgent need for evidence-based clinical guidelines for this neglected population.

Background:Giant cell arteritis (GCA) is the most common systemic vasculitis in adults, and the number of incident cases worldwide is projected to increase [1]. Evidence as to whether or not GCA confers a mortality risk is conflicting, and many studies have been limited by inadequate or lacking adjustment for confounders.Objectives:To investigate possible predictors of death in a large and well characterized Norwegian cohort of GCA-patients.Methods:This is a hospital-based retrospective cohort study including patients diagnosed with GCA during 1972-2012. Patients were identified through computerized hospital records using the International Classification of Diseases coding system. Clinical information was extracted from patients’ medical journals. Further details about the inclusion process have been published previously [2]. Information on time of death was obtained from the Norwegian Cause of Death Registry. We investigated predicting factors using Cox regression. Selected variables were first analyzed in univariate and block regression models (block 1: clinical features including histology, block 2: laboratory and treatment factors, block 3: demographic and traditional risk factors). Variables included in the final multivariate model were selected on the following basis: P-value <0.1 in univariate or block regression or otherwise deemed clinically significant.Results:881 patients were included of which 626 (71.1%) were females. Mean age was 73 years (SD 9). 490 patients (55.6%) died during the study period (1 January 1972 – 31 December 2012). Characteristics and mortality for the GCA-cohort compared to matched controls have been published previously [3]. Within the GCA-cohort we found that presenting with visual disturbance (any) or scalp necrosis was associated with increased risk of death in univariate analysis (Figure 1). However, in multivariate analysis the traditional risk factors (age, smoking, hypertension and previous cardiovascular disease) were more strongly associated with risk of death. Among laboratory parameters only Hemoglobin (Hb) levels were significantly associated with risk of death with increasing Hb-levels indicating decreased risk. Neither temporal artery biopsy result nor initial or maximal (before first tapering) Prednisolone dose were found to be associated with risk of death. Results from univariate and the final multivariate models are presented in Figure 1.Figure 1.Conclusion:In our large cohort of GCA-patients the risk of death was found to be predominantly predicted by age (HR 2.81) and traditional risk factors (smoking (HR 1.61), hypertension (HR 1.48) and previous cardiovascular disease (HR 1.26)). Visual disturbance (HR 1.40), visual loss in particular (HR 2.37), and scalp necrosis (HR 3.42) were found to be the clinical features most associated with risk of death. However, we note that our material lacked information about extra-cranial (large vessel) vasculitis, which may also carry increased risk of death.References:[1]De Smit E, Palmer AJ, Hewitt AW.

Abstract Background: Unlike SARS-CoV and MERS-C0V, SARS-CoV-2 can become a recurrent seasonal infection; hence, it is essential to compare the clinical spectrum of COVID-19 to the existent endemic coronaviruses. We conducted a retrospective cohort study of hospitalized patients with seasonal coronavirus (sCoV) infection and COVID-19 to compare their clinical characteristics and outcomes. Methods: A total of 190 patients hospitalized with any documented respiratory tract infection and a positive respiratory viral panel for sCoV from January 1, 2011, to March 31, 2020, were included. Those patients were compared with 190 hospitalized adult patients with molecularly confirmed symptomatic COVID-19 admitted from March 1, 2020, to May 25, 2020. Results: Among 190 patients with sCoV infection, the Human Coronavirus-OC93 was the most common coronavirus with 47.4% of the cases. When comparing demographics and baseline characteristics, both groups were of similar age (sCoV: 74 years vs. COVID-19: 69 years) and presented similar proportions of two or more comorbidities (sCoV: 85.8% vs. COVID-19: 81.6%). More patients with COVID-19 presented with severe disease (78.4% vs. 67.9%), sepsis (36.3% vs. 20.5%), and developed ARDS (15.8% vs. 2.6%) compared to patients with sCoV infection. Patients with COVID-19 had an almost 4-fold increased risk of in-hospital death than patients with sCoV infection (OR 3.86, CI1.99 – 7.49; p <.001). Conclusion: Hospitalized patients with COVID-19 had similar demographics and baseline characteristics to hospitalized patients with sCoV infection; however, patients with COVID-19 presented with higher disease severity, had a higher case fatality rate, and increased risk of death than patients with sCoV.

Objective We aimed to compare the efficacy and risks of proton pump inhibitor (PPI) versus histamine-2 receptor blocker (H2B) use for stress ulcer prophylaxis (SUP) in critically ill patients with sepsis and risk factors for gastrointestinal bleeding (GIB). Methods In this retrospective cohort study, we used the Medical Information Mart for Intensive Care III Clinical Database to identify critically ill adult patients with sepsis who had at least one risk factor for GIB and received either an H2B or PPI for ≥48 hours. Propensity score matching (PSM) was conducted to balance baseline characteristics. The primary outcome was in-hospital mortality. Results After 1:1 PSM, 1056 patients were included in the H2B and PPI groups. The PPI group had higher in-hospital mortality (23.8% vs. 17.5%), GIB (8.9% vs. 1.6%), and pneumonia (49.6% vs. 41.6%) rates than the H2B group. After adjusting for risk factors of GIB and pneumonia, PPI use was associated with a 1.28-times increased risk of in-hospital mortality, 5.89-times increased risk of GIB, and 1.32-times increased risk of pneumonia. Conclusions Among critically ill adult patients with sepsis at risk for GIB, SUP with PPIs was associated with higher in-hospital mortality and higher risk of GIB and pneumonia than H2Bs.

Abstract Background: Parvoviral enteritis is a viral gastrointestinal (GI) infection of dogs. Recovery from PE has been associated with persistent GI signs. The objectives of this study were: (i) To determine whether dogs that have recovered from PE (post-parvo dogs) had an increased risk of persistent GI signs compared to uninfected controls. (ii) To investigate the lifestyle and clinicopathologic factors that are associated with persistent GI signs in post-parvo dogs. Methods: Eighty-six post-parvo dogs and 52 age-matched control dogs were enrolled in this retrospective cohort study. The owners were interviewed about the health and habits of their dogs using a questionnaire. We used logistic regression to test whether parvovirus enteritis and other risk factors are associated with general health problems in all dogs and with persistent GI signs in post-parvo dogs.Results: The prevalence of persistent GI signs was significantly higher in post-parvo dogs compared to control dogs (57% vs 25%, P < 0.001). Markers of disease severity such as neutropenia, low body temperature, and treatment with an antiemetic medication (metoclopramide) were significant risk factors for persistent GI signs in post-parvo dogs. Persistent GI signs in post-parvo dogs was a risk factor for health problems in other organ systems.Conclusions: Parvovirus enteritis is a significant risk factor for persistent GI signs in dogs highlighting the importance of prevention. The risk factors identified in the present study may guide future investigations on the mechanisms that link parvovirus enteritis to chronic health problems in dogs.

Introduction: Surgical site infection (SSI) following hydrocelectomy is relatively uncommon, but it is one of the main post-operative problems. We aimed to describe the prevalence of SSI following hydrocelectomy among adult patients, and to assess predisposing risk factors for infection. Methodology: This retrospective cohort study was carried out at a university hospital and included hydrocelectomies performed between January 2007 and December 2014. Diagnosis of SSI was performed according to the Center for Diseases Control (CDC) guidelines. Multivariable logistic regression analysis was used to identify independent risk factors. Results: A total of 196 patients were included in the analysis. Overall, 30 patients were diagnosed with SSI (15.3%) and of these, 63.3% (19/30) were classified as having superficial SSI, while 36.7% (11/30) had deep SSI. The main signs and symptoms of infection were the presence of surgical wound secretion (70%) and inflammatory superficial signs such as hyperemia, edema and pain (60%). Among the 53 patients presenting chronic smoking habits, 26.4% (14⁄53) developed SSI, which was associated with a higher risk for SSI (odds ratio [OR] = 2.84, 95% confidence interval [CI] = 1.27 to 6.35, p < 0.01) in the univariate analysis. In the adjusted multivariable analysis, smoking habits were also statistically associated with SSI after hydrocelectomy (odds ratio [OR] = 2.84, 95% confidence interval [CI] = 1.30 to 6.24, p = 0.01). No pre-, intra-, or post-operative variable analyzed showed an independent association to SSI following hydrocelectomy. Conclusions: Smoking was the only independent modifiable risk factor for SSI in the multivariate analysis.

Background There is emerging evidence that rosacea, a chronic cutaneous inflammatory disease, is associated with various systemic diseases. However, its association with cardiovascular disease (CVD) remains controversial. We aimed to investigate whether patients with rosacea are at increased risk of developing CVD. Methods and Results This retrospective cohort study from the Korean National Health Insurance Service‐Health Screening Cohort included patients with newly diagnosed rosacea (n=2681) and age‐, sex‐, and index year–matched reference populations without rosacea (n=26 810) between 2003 and 2014. The primary outcome was subsequent CVD including coronary heart disease and stroke. Multivariable Cox regression analyses were used to evaluate adjusted hazard ratios for subsequent CVD adjusted for major risk factors of CVD. Compared with the reference population (13 410 women; mean [SD] age, 57.7 [9.2] years), patients with rosacea (1341 women; mean [SD] age, 57.7 [9.2] years) displayed an increased risk for CVD (adjusted hazard ratios, 1.20; 95% CI, 1.03–1.40) and coronary heart disease (adjusted hazard ratios, 1.29; 95% CI, 1.05–1.60). The risk for stroke was not significantly elevated (adjusted hazard ratios, 1.12; 95% CI, 0.91–1.37). Conclusions This study suggests that patients with rosacea are more likely to develop subsequent CVD. Proper education for patients with rosacea to manage other modifiable risk factors of CVD along with rosacea is needed.

Abstract Background Several studies have shown a possible causal relationship between the occurrence of systemic inflammation in patients with malignant disease and increased risk of cardiovascular events. Our objective was to estimate the association between malignant disease and postoperative cardiovascular complications. Secondarily, we aimed to identify risk factors for postoperative cardiovascular complications. Methods We conducted a retrospective cohort study of all patients ≥ 18 years undergoing emergency laparotomy between 2010 and 2016 at the Department of Surgery at Zealand University Hospital, Denmark. Complications were graded according to the Clavien-Dindo (CD) classification of surgical complications. A multivariate logistic regression analysis was performed to estimate the association between malignant disease and cardiovascular complications within 30 days of emergency laparotomy and to identify other risk factors for postoperative cardiovascular complications after emergency laparotomy. Results We identified 1188 patients ≥ 18 years undergoing emergency laparotomy between 2010 and 2016, in which 254 (21%) had malignant disease. Within 30 days of emergency laparotomy, 89 (9.5%) of patients without malignancy died, as compared with 45 (18%) of patients with malignancy (p < 0.001). Severe cardiovascular complication graded CD 3–5 occurred in 93 (8%) of all patients within 30 days of emergency laparotomy. We found no association between malignancy and postoperative cardiovascular complications. Increasing age and ASA physical status classification system (ASA) score ≥ III were the only independent risk factors of cardiovascular complications graded CD 3–5. Conclusions Malignancy was not associated with postoperative cardiovascular complications after emergency laparotomy. Risk factors for major cardiovascular complications after emergency abdominal surgery were age and ASA score ≥ III.
