Abstract Objective: To evaluate air quality in the waiting room of a pediatric emergency service considering the serial concentrations of particulate matter (PM2.5), and to determine if the number of people present in the room can have an influence on the pollutant concentrations. Methods: Cross-sectional study, carried out in the waiting room of a reference pediatric hospital in the city of Porto Alegre, conducted in a one-year period, in a continuous-time sample including all of the four seasons of the year. The monitoring of PM2.5 was performed using a real-time aerosol monitor (DustTrak II). The number of people in the room was determined every hour and the climatic characteristics per daily mean. The concentration of PM2.5 and the number of people were expressed by mean and standard deviation. The means were compared by Analysis of Variance and Pearson's correlation coefficient. Results: There was a significant increase in the concentration of PM2.5 in the autumn, when compared to other seasons (p<0.001). The pollutant increase, in this season, was accompanied by the higher number of people in the emergency room (p=0.026). The association between PM2.5 and the number of people is confirmed by the positive correlation between these two variables (r=0.738; p<0.001). Conclusions: The pediatric emergency waiting room showed elevated PM2.5 in all seasons. The number of people in the room had a positive correlation with the concentration of the pollutant in the environment.

Background: Cytomegalovirus (CMV) is a human herpesvirus common in people with human immunodeficiency virus (HIV). In a patient with immunocompetence, long periodic asymptomatic CMV might affect to develop the abnormal liver function and contribute to non-AIDS defining morbidity, including chronic liver disease. This study aims to know the prevalence of liver fibrosis and steatosis in virally suppressed HIV infected patients with CMV reactive and summarize the correlation of clinical presentation with liver fibrosis and steatosis in these subjects.Method: A cross-sectional study in HIV Integrated Care Unit, Cipto Mangunkusumo Hospital, was conducted from April 2019 until June 2020. Subjects enrolled in this study were suppressed HIV patients aged between 30-40 years with positive IgG CMV and already using stable ART for at least one year. Transient elastography measured the liver stiffness. Patients with liver stiffness above 7 kPa were defined as having significant liver fibrosis. In addition, Spearman correlation was conducted to evaluate the correlation of clinical presentation of subjects related to liver fibrosis and steatosis. Results: A total of subjects was included in this study. Dominantly male (62.5%) with average age 38 ± 4.68 years. The median amount of CMV DNA was 466 (17-21284) copy/ml. Significant Fibrosis was found in 17/80 (21%) subjects. In this study, clinical parameters correlated with liver fibrosis were insulin, glucose fasting, Homa IR, triglyceride, HDL, and platelet. A medium positive correlation was found in insulin, and Homa IR, with coefficient correlation for insulin, was r = 0.475, p 0.001; and coefficient correlation for Homa IR was r = 0 .487, p 0.001.Conclusion: The prevalence of liver fibrosis was 12% in these subjects. In addition, insulin and Homa IR had a positive correlation with increasing liver fibrosis.

Abstract Background and Aims Infectious complications represent the leading cause of death among the dialysis population, prompting early diagnosis and increased vigilance. Neutrophil-to-lymphocyte and platelets-to-lymphocyte ratios are newly emerging as more accessible and simple markers for the detection of the onset of infections. The objective of our study is to prove the value of these markers in the diagnosis of infections in hemodialysis patients. Method This is a cross-sectional study spread over one year including 85 chronic hemodialysis patients with duration of at least 6 months. patients with hemopathies, tumors, or with a history of hospitalization during the 3 months before the study were excluded. CRP was used as a biomarker of infections and N / L; P / L ratios were calculated to study the correlation between the two biomarkers. Based on the literature reviews, the threshold of the N / L ratio and the P / L ratio admitted for our stydy were respectively : &gt; = 2.5 and &gt; = 150. Results The mean age of our patients was 49 ± 19 years with a predominance of women (55%) .The average duration in hemodialysis was 67.2 months. An infectious complication was noted in 22% of our patients whose distribution was as follow: 4% as a pulmonary infection with 3 coronavirus cases, 6% a sepsis, one case of abscess of the nephrectomy compartment.The median value of the CRP was 37±10mg/l We found a positive correlation between the 2 ratios associated (RNL and RPL) and infection with (p = 0.03) . We noted throw this study that patients with both high ratios RPL&gt; 150 and RNL&gt; 2.5 have significantly elevated values of CRP. Conclusion N/L and P/L ratios are easy-to-calculate markers that are of great benefit to the hemodialysis population. We have shown through this study the existence of a positive correlation between the N/L and P/L ratios and the occurrence of infections in hemodialysis patients. We therefore encourage the use of this ratios to be included as markers to detect infections occurence.

Background: In evaluation of non-traumatic subarachnoid hemorrhage CT angiography (CTA) has 97-98% sensitivity and near 100% specificity. Objective: This study was conducted to evaluate the CTA findings of CT positive non traumatic subarachnoid hemorrhage. Methodology: This is an observational cross sectional study performed in Neurology department of National Institute of Neurosciences and Hospital, Dhaka over one year period (January 2019 to December 2019). Total 87 CT positive subarachnoid hemorrhage cases were purposively included in this study. All CT positive patients underwent CTA of Cerebral vessels for further evaluation. The angiography were evaluated by competent neuro-radiologists blinded about the study. Result: Among 87 patients, 40.2% were male and 59.8% were female. The average age was 53.33±11.1 years. Among the studied patient the source of bleeding was found 78.16% aneurysmal and 21.84% non-aneurysmal. 85.30% patients had single aneurysm and 14.70% had multiple aneurysm. The highest number of patient had Acom aneurysm (41.17%) followed by MCA (22.05%), ICA (13.23%), ACA (7.35%) and vertebral artery (1.14%) in order of frequency. Among the multiple aneurysm group most of the patients had combination of Acom, MCA and ICA aneurysm. Conclusion: From this study, we can conclude that CTA can be used as the primary diagnostic tool in evaluation of spontaneous SAH.

Aims: The etiopathogenesis of Rheumatoid Arthritis (RA) is not clearly understood. However, the role of the cytokines takes an important part in this mechanism. We aimed to bring a new approach to the concept of 'remission' in patients with RA. Background: RA is a chronic, autoimmune, inflammatory disease that involves small joints in the form of symmetrical polyarthritis and progresses with exacerbations and remissions. Pain, swelling, tenderness and morning stiffness are typical of the joints involved. Although it is approached as a primary joint disease, a wide variety of extra-articular involvements may also occur. It is an interesting pathophysiological process, the exact cause of which is still unknown, with many environmental, genetic and potentially undiscovered possible factors in a chaotic manner. Objective: In this cross-sectional study, sedimentation rate (ESR), C- Reactive protein (CRP), Tumor necrosis factor (TNF)-α, soluble-TNF-α receptor (TNF-R), Interleukin (IL)-1B and IL-10 were measured in three groups which were healthy volunteers, patients with RA in the active period, and patients with RA in remission. Disease activity score-28 (DAS-28) was calculated in active RA and RA in remission. Methods: This study included 20 healthy volunteers, 20 remission patients with RA and 20 active RA patients. Venous blood samples were collected from patients in both healthy and RA groups. Results: RA group consisted 43 (71.6%) female and 17 (28.4%) male. Control group consisted 11 (55%) female and 9 (45%) male. TNF-R was significantly high only in the active group according to the healthy group (p=0.002). IL-10 was significantly high in active RA according to RA in remission (p=0.03). DAS-28 was significantly high in active RA according to RA in remission (p=0.001). In the active RA group, ESR and TNF-R had a positive correlation (r:0.442; p=0.048). In the active RA group, there was also a positive correlation between TNF-R and CRP (r:0.621; p=0,003). Both healthy and active RA group had significant positive correlation between ESR and CRP (r: 0.481; p=0.032 and r: 0,697; p=0,001 respectively). Conclusion: TNF-R can be the main pathophysiological factor and a marker showing activation. TNF-R can be very important in revealing the effect of TNF on the disease and the value of this effect in the treatment and ensuring the follow-up of the disease with CRP instead of ESR in activation.

Urgent care (UC) is one of the fastest growing venues of health care delivery for nonemergent conditions. This study compared the patient experience during virtual and in-person urgent care visits. We conducted a cross-sectional study of patients with the same diagnosis during Virtual Urgent Care (VUC) and in-person UC visits with the same diagnosis with regard to time and cost over a period of one year. We recorded and analyzed 16 685 urgent care visits: In-person UC (n = 14 734), VUC (n = 1262). Significant differences were found in the average total time for a visit in an in-person UC (70.89 minutes), and VUC (9.38 minutes). The average total cost of VUC ($49) and in-person UC ($142.657) differed significantly. Significant difference was found between UC turnaround time and VC turnaround time (Dependent variable (DV): 53.77, P < .01). We found significant differences in cost and time between in favor of virtual visits. Our findings suggest additional policy reform to expand the use of virtual care among target populations to improve access, reduce costs, meet the needs of patients, and reduce emergency department visits.
