While their clinical presentation is similar, post-viral rhinosinusitis does not indicate the possible development of bacterial rhinosinusitis which occurs in only 0.5% to 5% of all cases of ARS. However, unreasonable antibacterial therapy is prescribed in 54% to 77% of cases. The perspective is to use delayed antibacterial therapy management. The purpose of the study was to investigate the efficacy of mometasone furoate nasal spray within the delayed prescription approach. Methods: A multicenter, randomized, open-label, comparative, prospective, parallel group study enrolled a total of 156 patients with ARS aged 18 to 60 years, of them 155 patients completed the study. The patients were randomized into the main group of Mometasone Furoate (Flix) Nasal Spray or into the control group of amoxicillin clavulanate tablets while both groups were administered a standard ARS therapy. Findings: The use of MF nasal spray within the delayed antibiotics prescription approach has a significantly higher efficacy compared to the immediate antibiotics prescription in the first days of treatment (p < 0.05). Antibacterial therapy was prescribed to 42.3% of patients in the main group compared to 100.0% of patients in the control group (p < 0.05). It was shown that there were statistically significant differences in the dynamics of changes in the total symptom score between the patients administered antibiotics and the antibiotic-naive patients. Conclusion: The use of MF within the delayed antibiotics prescription approach reliably improves the pattern of symptoms over time at the disease onset and significantly reduces the need for NSAIDs administration and antibiotics prescription frequency.

Background: The Marburg virus (MARV) is the causative agent of Marburg virus disease (MVD). This filovirus first appeared in 1967 and has since caused several outbreaks with case fatality rates between 23% and 90%. The earliest cases of MVD are thought to be caused by exposure to an infected animal, either a reservoir host (some bat species, e.g., Rousettus aegyptiacus) or a spill-over host, such as non-human primates. The virus is spread between people by direct contact with blood or other bodily fluids (including saliva, sweat, faeces, urine, tears, and breast milk) from infected individuals. Despite the high fatality rate, the Marburg virus has no vaccine or drug treatment. Recent outbreaks of the virus in 2023 in Tanzania and Equatorial Guinea have reignited the need to develop effective therapeutics, especially in the wake of the COVID-19 pandemic. Purpose: This review seeks to highlight the drug discovery efforts aimed at developing vaccines or possible treatments as potential therapeutics. Several existing antiviral agents are being probed, and vaccines are in pre-clinical and clinical stages. Natural products are also an important source of possible drugs or lead compounds and when coupled with computational techniques, these strategies offer possible therapeutics for the Marburg virus, especially in Africa, which has a high disease burden. Methods: Using the search engines Google Scholar and PubMed;keywords e.g. Marburg virus, Marburg treatments, Marburg virus drug discovery were utilized. Several results were yielded, and articles published in recent years were accepted into the final *** and Conclusion: This study shows there is a growing interest in therapeutics for the Marburg virus, especially with the recent outbreaks and pandemic preparedness. Initiatives that to support vaccine development and access like the MARVAC consort time are critical to fighting this public health threat.

作者： natalia Cristina Aparecida Ribeiro e Ribeiro Anderson Martins Tavares Jaslana Hainfellner da Silva João Paulo Lima Daher Salim Kanaan Luciene de Carvalho Cardoso-Weide Laboratory of Neuroplasticity Neurobiology Department Biology Institute Federal Fluminense University Rio de Janeiro Brazil Postgraduate Program in Medical Sciences School of Medicine Federal Fluminense University Rio de Janeiro Brazil School of Biology UNIVERSO—Salgado de Oliveira University Rio de Janeiro Brazil Department of Pathology Faculty of Medicine Federal Fluminense University Rio de Janeiro Brazil

It consists of a retrospective study with twenty-two individuals diagnosed with DRC: fourteen HD and eight CAPD, followed up in the dialysis center of Antonio Pedro University Hospital (HUAP) of Fluminense Federal University (UFF), between 2015 and 2017. Fifteen healthy control (HC) subjects were included, without diagnosed CKD. Patients with HIV positive, hepatitis A, B, and C, pregnant, cancer, smokers, alcoholics and those exposed to X-rays in the last 3 months, were excluded. Objectives: As oxidative stress and endothelial dysfunction may be linked to the higher prevalence of CVD in CKD patients, we measured the activities of the antioxidants enzymes: SOD and GPx and total NO levels in the plasma and serum of end-stage CKD patients undergoing dialysis therapy, comparing with the HC group. Methods: Quantification of NO levels was performed by fluorometric kit, while activities of SOD and GPx were determined using kinetic methods. Results: We found higher plasma SOD activity in HD (8.58 U/ml) and CAPD (10.14 U/ml), compared to C (3.73 U/ml) group, while GPx activity was decreased in HD (115.38 nmol/h/ml) and CAPD (122.76 nmol/h/ml) groups compared to HC group (275.83 nmol/h/ml). Total serum NO concentration was decreased in HD (14.09 pmol/μl) and CAPD (10.26 pmol/μl), compared to non-CKD patients (49.65 pmol/μl). Conclusion: Decreased total serum NO and GPx activities may lead to endothelial dysfunction and consequently a higher prevalence of CVD in CKD patients.

Mechanical Complications after Myocardial Infarction: A Comprehensive Review

引用

World Journal of Cardiovascular Diseases 2024年第1期14卷 43-60页

作者： Alexis D. Aparicio-Ortiz María natalia Alonso-Jimenez Adrian Espejel-Guzman Aldo Cabello-Ganem Javier Serrano-Roman Santiago Luna-Alcala Nilda Espinola-Zavaleta Department of Nuclear Cardiology National Institute of Cardiology Ignacio Chavez Mexico City Mexico Department of Echocardiography ABC Medical Center Mexico City Mexico

Mechanical complications of myocardial infarction are potentially fatal events that can occur after an acute myocardial infarction. While the introduction of primary percutaneous reperfusion and fibrinolysis has reduced the incidence of these complications to less than 1%. These complications pose significant hemodynamic consequences and necessitate prompt diagnosis. Echocardiography, cardiac magnetic resonance imaging, and computed tomography are valuable tools for establishing an accurate and expedited diagnosis. Consequently, it is imperative to conduct further scientific research to enhance hemodynamic stabilization techniques such as intra-aortic balloon counterpulsation and extracorporeal membrane oxygenation, in addition to exploring new surgical procedures that can reduce mortality resulting from mechanical complications. This article aims to provide a comprehensive review of mechanical complications following myocardial infarction and their correlation with multi-imaging, facilitating a better understanding of these complications.

Hepatitis C virus and ethanol alter antigen presentation in liver cells

引用

World Journal of Gastroenterology 2009年第10期15卷 1201-1208页

作者： natalia A Osna Department of Internal Medicine University of Nebraska Medical Center Liver Study Unit R151 VA Medical Center 4101 Woolworth Ave Omaha NE 68105 United States

Alcoholic patients have a high incidence of hepatitis C virus （HCV） infection. Alcohol consumption enhances the severity of the HCV disease course and worsens the outcome of chronic hepatitis C. The accumulation of virally infected cells in the liver is related to the HCV- induced inability of the immune system to recognize infected cells and to develop the immune responses. This review covers the effects of HCV proteins and ethanol on major histocompatibility complex （MHC） class Ⅰ- and class Ⅱ-restricted antigen presentation. Here, we discuss the liver which functions as an immune privilege organ; factors, which affect cleavage and loading of antigenic peptides onto MHC class I and class ~I in hepatocytes and dendritic cells, and the modulating effects of ethanol and HCV on antigen presentation by liver cells. Altered antigen presentation in the liver limits the ability ＇of the immune system to clear HCV and infected cells and contributes to disease progression. HCV by itself affects dendritic cell function, switching their cytokine profile to the suppressive phenotype of interleukin-10 （IL-10） and transforming growth factor beta （TGFβ） predominance, preventing cell maturation and allostimulation capacity. The synergistic action of ethanol with HCV results in the suppression of MHC class Ⅱ-restricted antigen presentation. In addition, ethanol metabolism and HCV proteins reduce proteasome function and interferon signaling, thereby suppressing the generation of peptides for MHC class I -restricted antigen presentation. Collectively, ethanol exposure further impairs antigen presentation in HCV-infected liver cells, which may provide a partial explanation for exacerbations and the poor outcome of HCV infection in alcoholics.

The comparison of design airflow rates with dynamic and steady-state displacement models in varied dynamic conditions

引用

Building Simulation 2021年第4期14卷 1201-1219页

作者： natalia Lastovets Risto Kosonen Juha Jokisalo Department of Mechanical Engineering Aalto UniversityEspooFinland College of Urban Construction Nanjing Tech UniversityNanjingChina

A temperature-based method is usually applied in displacement ventilation (DV) design when overheating is the primary indoor climate concern. Different steady-state models have been developed and implemented to calculate airflow rate in rooms with DV. However, in practical applications, the performance of DV depends on potentially dynamic parameters, such as strength, type and location of heat gains and changing heat gain schedule. In addition, thermal mass affects dynamically changing room air temperature. The selected steady-state and dynamic models were validated with the experimental results of a lecture room and an orchestra rehearsal room. Among the presented models, dynamic DV model demonstrated a capability to take into account the combination of dynamic parameters in typical applications of DV. The design airflow rate is calculated for the case studies of dynamic DV design in the modelled lecture room in both dynamic and steady-state conditions. In dynamic conditions of heavy construction in 2–4 hours occupancy periods, the actual airflow rate required could be 50% lower than the airflow rate calculated with the steady-state models. The difference between steady-state and dynamic multi-nodal model is most significant with heavyweight construction and short occupancy period (17%–28%). In cases with light construction, the dynamic DV model provides roughly the same airflow rates for four-hour occupancy period than the Mund’s model calculates. The dynamic model can significantly decrease the design airflow rate of DV, which can result in a reduction of investment costs and electrical consumption of fans.
