Diese ist potenziell lebensbedrohlich, da sie zu Aspiration und Pneumonie führen kann. Vor einer oralen Nahrungsgabe sollte daher unbedingt eine Schluckdiagnostik mittels Bolusfärbetest und/oder FEES durchgeführt werden. Da ein physiologischer Luftstrom durch den Larynx und ein adäquater subglottischer Druck Schlüsselkomponenten eines effektiven Schluckaktes sind, sollte eine Oralisierung bei geblockter Trachealkanüle möglichst vermieden werden.

Esthetic and clinical outcomes after immediate placement and restoration: Comparison of two implant systems in the anterior maxilla—A cross‐sectional study

alexandrossfakianakis shared this article with you from Inoreader Esthetic and clinical outcomes after immediate placement and restoration: Comparison of two implant systems in the anterior maxilla—A cross‐sectional study via Clinical Implant Dentistry and Related Research Abstract Aim To assess the esthetic and clinical performance of a novel self-tapping implant system for single-tooth restorations in the esthetic zone after immediate placement and provisionalization. Materials and Methods This cross-sectional study included 52 patients contributing a total of 52 immediately placed and restored implants with ≥12 months after functional loading, comparing two different implant systems: Straumann® BLX (Institut Straumann AG, Basel, Switzerland; 25 patients) and Ankylos® (Dentsply Sirona, Hanau, Germany; 27 patients). As the primary outcome measure, peri-implant tissue esthetics were assessed by means of pink esthetics score (PES) rated by three independent clinicians. Moreover, as secondary outcome measures, the peri-implant tissue health was assessed by means of bleeding on probing, probing depth, and suppuration. Apart from that, the modified plaque index, keratinized mucosa width, and the presence of mucosal recessions were also assessed. When clinical signs suggested the possibility of peri-implantitis, radiographs were indicated to assess progressive bone loss. Results The mean PES ratings were 12.10 ± 1.10 for Ankylos versus 11.2 ± 1.86 for BLX, both achieving good esthetic results without significant differences (p = 0.143). There were no differences among most clinical parameters (plaque, bleeding on probing, probing depth, peri-implant mucosal recession), although peri-implant mucositis was present in one-third of the cases. The inter-rater agreement on esthetics was not significant (p < 0.250). Conclusion Within the limitations of the present study, it was concluded that the use of either BLX or Ankylos implant systems was associated to comparable peri-implant health and good pink esthetic outcomes during immediate implantation and restoration protocols, for at least 12 months.

Transmitted drug resistance to integrase based first-line HIV antiretroviral regimens in the Mediterranean Europe

alexandrossfakianakis shared this article with you from Inoreader Transmitted drug resistance to integrase based first-line HIV antiretroviral regimens in the Mediterranean Europe via Clinical Infectious Diseases Advance Access Abstract Objective To study the prevalence of transmitted drug resistance (TDR) to INSTIs and NRTIs, and of clinically relevant resistance (CRR), in newly-diagnosed people with HIV (PWH) naïve to antiretroviral therapy (ART) in Europe. Methods MeditRes HIV is a consortium that includes ART naïve PWH newly diagnosed in France, Greece, Italy, Portugal, and Spain during the years 2018-2021. Reverse transcriptase (RT) and Integrase (INSTI) sequences were provided by participating centers. To evaluate the prevalence of surveillance drug resistance mutations (SDRM) we used the CPR tools from Stanford HIV-website. To evaluate clinically relevant resistance (CRR), defined as any resistance level >= 3, we used the Stanford v.9.1HIVDB Algorithm. Results We included 2705 PWH, 72% men, median age of 37 (IQR, 30-48); 43.7% infected by non-B subtypes. The prevalence of INSTI-SDRMs was 0.30% (T66I, T66A, E92Q, E138T, E138K, Y143R, S147G and R263K, all n = 1), and of NRTI-SDRMs was 5.77% (M184V n = 23, 0.85%; M184I n = 5, 0.18%; K65R/N n = 3, 0.11%; K70E n = 2, 0.07%; L74V/I n = 5, 0.18%; any TAMs n = 118, 4.36%). INSTI-CRR was 2.33% (0.15% dolutegravir/bictegravir; 2.29% raltegravir/elvitegravir), and 1.74% to first-line NRTIs (0.89% tenofovir/tenofovir alafenamide fumarate; 1.74% abacavir; 1.07% lamivudine/emtricitabine). Conclusions We present the most recent data on TDR to integrase based first-line regimens in Europe. Given the low prevalence of CRR to second generation integrase inhibitors and to first-line NRTIs, in the years 2018-2021 it is unlikely that newly diagnosed PWH in MeditRes countries would present with baseline resistance to a first-line regimen based on second generation integrase inhibitors.

Risk of waning humoral responses after inactivated or subunit recombinant SARS‐CoV‐2 vaccination in patients with chronic diseases: Findings from a prospective observational study in China

alexandrossfakianakis shared this article with you from Inoreader Risk of waning humoral responses after inactivated or subunit recombinant SARS‐CoV‐2 vaccination in patients with chronic diseases: Findings from a prospective observational study in China via Journal of Medical Virology Abstract Heterogeneity of antibody responses has been reported in SARS-CoV-2 vaccination recipients with underlying diseases. We investigated the impact of the presence of comorbidities on the humoral response to SARS-CoV-2 vaccination in patients with chronic disease (PWCD) and assessed the effect of the number of comorbidities on the humoral response to vaccination. In this study, neutralizing antibodies (NAbs) and IgG antibodies against the receptor-binding domain (RBD-IgG) were monitored following a full-course vaccination. In total, 1400 PWCD (82.7%, inactivated vaccines; 17.3%, subunit recombinant vaccine) and 245 healthy controls (65.7% inactivated vaccines, 34.3% subunit recombinant vaccine) vaccinated with inactivated or subunit recombinant SARS-CoV-2 vaccines, were included. The seroconversion and antibody levels of the NAbs and RBD-IgG were different in the PWCD group compared with those in the control group. Chronic hepatitis B (odds ratio [OR]: 0.65; 95% confidence interval [C I]: 0.46–0.93), cancer (OR: 0.65; 95% CI: 0.42–0.99), and diabetes (OR: 0.50; 95% CI: 0.28–0.89) were associated with lower seroconversion of NAbs. Chronic kidney disease (OR: 0.29; 95% CI: 0.11–0.76), cancer (OR: 0.38; 95% CI: 0.23–0.62), and diabetes (OR: 0.37; 95% CI: 0.20–0.69) were associated with lower seroconversion of RBD-IgG. Only the presence of autoimmune disease showed significantly lower NAbs and RBD-IgG titers. Patients with most types of chronic diseases showed similar responses to the controls, but humoral responses were still significantly associated with the presence of ≥2 coexisting diseases. Our study suggested that humoral responses following SARS-CoV-2 vaccination are impaired in patients with certain chronic diseases. This article is protected by copyright. All rights reserved.

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.

No Association of IFNL4 Genotype With Opportunistic Infections and Cancers Among Men With Human Immunodeficiency Virus 1 Infection

alexandrossfakianakis shared this article with you from Inoreader No Association of IFNL4 Genotype With Opportunistic Infections and Cancers Among Men With Human Immunodeficiency Virus 1 Infection via Clinical Infectious Diseases Advance Access Abstract Background IFNL4 genetic variants that are strongly associated with clearance of hepatitis C virus have been linked to risk of certain opportunistic infections (OIs) and cancers, including Kaposi sarcoma, cytomegalovirus infection, and herpes simplex virus infection. As the interferon (IFN) λ family plays a role in response to viral, bacterial, and fungal infections, IFNL4 genotype might affect risk for a wide range of OIs/cancers. Methods We examined associations between genotype for the functional IFNL4 rs368234815 polymorphism and incidence of 16 OIs/cancers among 2310 men with human immunodeficiency virus (2038 white; 272 black) enrolled in the Multicenter AIDS Cohort Study during 1984–1990. Our primary analyses used Cox proportional hazards models adjusted for self-reported racial ancestry to estimate hazard ratios with 95% confidence intervals, comparing participants with the genotypes that generate IFN-λ4 and those with the genotype that abrogates IFN-λ4. We censored follow-up at the introduction of highly effective antiretroviral therapies. Results We found no statistically significant association between IFNL4 genotype and the incidence of Kaposi sarcoma (hazard ratio, 0.92 [95% confidence interval, .76–1.11]), cytomegalovirus infection (0.94 [.71� �1.24]), herpes simplex virus infection (1.37 [.68–2.93]), or any other OI/cancer. We observed consistent results using additive genetic models and after controlling for CD4 cell count through time-dependent adjustment or restriction to participants with a low CD4 cell count. Conclusions The absence of associations between IFNL4 genotype and these OIs/cancers provides evidence that this gene does not affect the risk of disease from opportunistic pathogens. View on Web

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
