Viruses Responsible for Acute Respiratory Infections Before (2016‐2019) and During (2021) Circulation of the SARS‐CoV‐2 virus in Pediatric Patients in a Reference Center at Barranquilla Colombia: A Pattern Analysis

alexandrossfakianakis shared this article with you from Inoreader Viruses Responsible for Acute Respiratory Infections Before (2016‐2019) and During (2021) Circulation of the SARS‐CoV‐2 virus in Pediatric Patients in a Reference Center at Barranquilla Colombia: A Pattern Analysis via Journal of Medical Virology Summary Objective To evaluate the behavior of the viruses responsible for acute respiratory infections before (2016-2019) and after (2020-2021) the start of the circulation of the SARS-CoV-2 virus in pediatric patients treated at a reference center from Barranquilla, Colombia. Materials and methods A descriptive observational study was carried out, and data were obtained by reviewing the influenza-like illness and severe acute respiratory infection database in the pediatric population of the sentinel surveillance reference center in the district of Barranquilla during the years 2016 - 2021, applying inclusion and exclusion criteria. Results During 2016-2019, the average age of individuals was 1.3 (±1.7) years, during 2021, it was 2.3 (±3.5) years. The distribution by sex was similar, predominantly male. August and February were the months with the highest record of symptoms for 2016-2019 and 2021, respectively, the most frequent being cough, fever, shortness of breath, and diarrhea. By 2021 there was a higher use of antibiotics and antivirals reported than in 2016-2019. Most patients tested negative for viral detection. When comparing the percentage of viruses detected by age group and years of detection, positivity was lower in 2021 by every age group, and respiratory Syncytial Virus (RSV) was the most frequently detected. Conclusions There was less virus positivity in viral detection tests in the pediatric population in 2021. RSV persists as the main etiology affecting this population, especially infants. The use of antibiotic therapy in viral infections continues to be a problematic practice in their management. Sentinel surveillance can be strengthened throughout the country.

The HBV web: An insight into molecular interactomes between the Hepatitis B virus and its host en route to hepatocellular carcinoma.

alexandrossfakianakis shared this article with you from Inoreader The HBV web: An insight into molecular interactomes between the Hepatitis B virus and its host en route to hepatocellular carcinoma. via Journal of Medical Virology ABSTRACT Hepatitis B virus (HBV) is a major aetiology associated with the development and progression of hepatocellular carcinoma (HCC), the most common primary liver malignancy. Over the past few decades, direct and indirect mechanisms have been identified in the pathogenesis of HBV-associated HCC which include altered signaling pathways, genome integration, mutation-induced genomic instability, chromosomal deletions and rearrangements. Intertwining of the HBV counterparts with the host cellular factors, though well established, needs to be systemized to understand the dynamics of host-HBV crosstalk and its consequences on HCC progression. Existence of a vast array of protein-protein and protein-nucleic acid interaction databases has led to the uncoiling of the compendia of genes/gene products associated with these interactions. This review covers the existing knowledge about the HBV-host interplay and brings it down under one canopy emphasizing on the HBV-host interactomics; and thereby highlights new strategies for therapeutic advancements against HBV-induced HCC.

Infectivity of pseudotyped SARS‐CoV‐2 variants of concern in different human cell types and inhibitory effects of recombinant spike protein and entry‐related cellular factors

alexandrossfakianakis shared this article with you from Inoreader Infectivity of pseudotyped SARS‐CoV‐2 variants of concern in different human cell types and inhibitory effects of recombinant spike protein and entry‐related cellular factors via Journal of Medical Virology Abstract Since the report of the first COVID-19 case in 2019, SARS-CoV-2 variants of concern (VOCs) have continued to emerge, manifesting diverse infectivity, evasion of host immunity and pathology. While ACE2 is the predominant receptor of SARS-CoV-2, TMPRSS2, Kim-1, NRP-1, CD147, furin, CD209L and CD26 have also been implicated as viral entry-related cofactors. To understand the variations in infectivity and pathogenesis of VOCs, we conducted infection analysis in human cells from different organ systems using pseudoviruses of VOCs including Alpha, Beta, Gamma and Delta. Recombinant spike S1, RBD, ACE2, Kim-1 and NRP-1 proteins were tested for their ability to block infection to dissect their roles in SARS-CoV-2 entry into cells. Compared with wild type SARS-CoV-2 (WT), numerous VOCs had significant increases of infectivity across a wide spectrum of cell types. Recombinant ACE2 protein more effectively inhibited the infection of VOCs including Delta and Omicron (BA .1 and BA.2) than that of WT. Interestingly, recombinant S1, RBD, Kim-1 and NRP-1 proteins inhibited the infection of all pseudoviruses in a manner dependent on the levels of ACE2 expression in different cell types. These results provide insights into the diverse infectivity of SARS-CoV-2 VOCs, which might be helpful for managing the emergence of new VOCs. This article is protected by copyright.

Bartonella quintana transmitted by head lice: an outbreak of trench fever in Senegal

alexandrossfakianakis shared this article with you from Inoreader Bartonella quintana transmitted by head lice: an outbreak of trench fever in Senegal via Clinical Infectious Diseases Advance Access Abstract Background Louse-borne trench fever caused by Bartonella quintana is a neglected public health concern, known to be transmitted from body louse faeces via scratching. No viable B. quintana have ever been isolated from head lice before; therefore, their role as a vector is still poorly understood. Methods In Senegal, the implementation of a permanent local surveillance system in a Point-of-Care laboratory (POC) allows the monitoring of emerging diseases. Here, we used culture as well as molecular and genomic approaches to document an outbreak of trench fever associated with head lice in the village of Ndiop. Head lice and blood samples were collected from febrile patients between November 2010 and April 2015. Genomes of two isolated strains of B. quintana were sequenced and analysed. Results A total of 2,289 blood samples were collected in the 2010-2015 period. From 2010-2013, B. quintana DNA was detected by PCR in 0.25% (4/1,580). In 2014, 228 blood samples were collected, along with 161 head lice from five individuals. B. quintana DNA was detected in 4·4% (10/228) of blood samples, and in lice specimens collected from febrile patients (61·7%, 50/81) and non-febrile patients (61·4%, 43/70). Two B. quintana strains were isolated from blood and head lice from two different patients. Genomic sequence analysis showed 99·98% overall similarity between both strains. Conclusion The presence of live B. quintana in head lice, and the genetic identity of strains from patients' blood and head lice during a localised outbreak in Senegal, supports the evidence of head lice vectorial capacity.

Mitotic count is prognostic in IDH-mutant astrocytoma without homozygous deletion of CDKN2A/B. Results of consensus panel review of EORTC trials 26053 and EORTC 22033-26033

alexandrossfakianakis shared this article with you from Inoreader Mitotic count is prognostic in IDH-mutant astrocytoma without homozygous deletion of CDKN2A/B. Results of consensus panel review of EORTC trials 26053 and EORTC 22033-26033 via Neuro-Oncology Advance Access Abstract Background Gliomas with IDH1/2 mutations without 1p19q codeletion have been identified as the distinct diagnostic entity of IDH mutant astrocytoma (IDHmut astrocytoma). Homozygous deletion of Cyclin-dependent kinase 4 inhibitor A/B (CDKN2A/B) has recently been incorporated in the grading of these tumors. The question of whether histologic parameters still contribute to prognostic information on top of the molecular classification, remains unanswered. Here we evaluated consensus histologic parameters for providing additional prognostic value in IDHmut astrocytomas. Methods An international panel of seven neuropathologists scored 13 well-defined histologic features in virtual microscopy images of 192 IDHmut astrocytomas from EORTC trial 22033-26033 (low-grade gliomas) and 263 from EORTC 26053 (CATNON) (1p19q non-codeleted anaplastic glioma). For 192 gliomas the CDKN2A/B status was known. Consensus (agreement ≥ 4/7 panelists) hi stologic features were tested together with homozygous deletion (HD) of CDKN2A/B for independent prognostic power. Results Among consensus histologic parameters, the mitotic count (cut-off of 2 mitoses per 10 high power fields standardized to a field diameter of 0.55 mm and an area of 0.24 mm 2) significantly influences PFS (p = 0.0098) and marginally the OS (p = 0.07). Mitotic count also significantly affects the PFS of tumors with HD CDKN2A/B, but not the OS, possibly due to limited follow-up data. Conclusion The mitotic index (cut-off 2 per 10 40x HPF) is of prognostic significance in IDHmut astrocytomas without HD CDKN2A/B. Therefore, the mitotic index may direct the therapeutic approach for patients with IDHmut astrocytomas with native CDKN2A/B status. View on Web
