t for HPV-related and non-related OPSCC, it is necessary to accumulate cases for the accurate HPV determination and comparison of treatment effects.
The purpose of this study was to analyse the oncologic results of open partial horizontal laryngectomy (OPHL) and to assess the prognostic factors that could affect the survival of patients affected by T2, T3 and T4a laryngeal cancer. Using this data, we aim to identify clinical criteria to select patients amenable to conservative surgery, and to facilitate a more targeted approach in the management of advanced laryngeal cancer.

A retrospective study was performed in patients who underwent OPHL type II for laryngeal squamous cell carcinoma from January 2005 to December 2018. We analysed a total of 170 patients; 21(12.36%) cases were staged as pT2, 116 (68.23%) as pT3 and 33 (19.41%) as pT4a.

Five-year overall survival (OS) was 80.9%, 79.3%, 70.4% for T2, T3 and T4 respectively. Disease-specific survival (DSS) was 90.4%, 85.3% and 77.4%. Posterior tumour extension, perineural invasion and N status showed to considerably influence survival in both uni- and multivariate analyses.

The oncological outcomes from our study show that OPHL for advanced laryngeal cancer can guarantee a high percentage of success. Accurate patient selection is of utmost importance to differentiate advanced disease amenable to conservative surgery, and treatment options should consider selected criteria based on tumour and patient features.

In this work, we describe a MALDI-MS-based N-glycomic analysis with multivariate data analysis approach for exploration and classification of the patients with OC. Various statistical analyses were used to determine differential N-glycome profiles. There were 8 glycan structures significantly increased (p  less then  0.05) in all OC-derived microvesicles (MVs). Importantly, the increases in these glycans were significantly greater in the early stage of OC than those in the advanced stage of OC. Additionally, N-glycomic profiles from the serum were also performed, demonstrating a significant change of 11 glycan structures (p  less then  0.05). Our data highlighted the effectiveness approach of MALDI-MS-based MV N-glycomic profiling on OC screening, and presented strong potential for further identifying targeted glycoproteomics signatures of the cancer.Mycotoxins are low molecular weight toxic compounds, which can cause severe health problems in animals and humans. Immunoassays allow rapid, simple and cost-effective screening of mycotoxins. Sandwich assays with a direct readout provide great improvement in terms of selectivity and sensitivity, compared to the widely used competitive assay formats, for the analysis of low molecular weight molecules. In this work, we report a non-competitive fluorescence anti-immune complex (IC) immunoassay, based on the specific recognition of HT-2 toxin with a pair of recombinant antibody fragments, namely antigen-binding fragment (Fab) (anti-HT-2 (10) Fab) and single-chain variable fragment (scFv) (anti-IC HT-2 (10) scFv). The SpyTag and SpyCatcher glue proteins were applied for the first time as a bioconjugation tool for the analysis of mycotoxins. To this aim, a SpyTag-mScarlet-I (fluorescent protein) and scFv-SpyCatcher fusion proteins were constructed, produced and fused in situ during the assay by spontaneous Tag-Catcher binding. The assay showed an excellent sensitivity with an EC50 of 4.8 ± 0.4 ng mL-1 and a dynamic range from 1.7 ± 0.3 to 13 ± 2 ng mL-1, an inter-day reproducibility of 8.5% and a high selectivity towards HT-2 toxin without cross-reactivity with other Fusarium toxins. The bioassay was applied to the analysis of the toxin in an oat reference material and in oat samples, with a LOD of 0.6 µg kg-1, and the results were validated by analysing a certificate reference material and by HPLC-MS/MS.Acetaminophen (APAP) overdose can cause hepatotoxicity and even liver failure. N-acetylcysteine (NAC) is still the only FDA-approved antidote against APAP overdose 40 years after its introduction. The standard oral or intravenous dosing regimen of NAC is highly effective for patients with moderate overdoses who present within 8 h of APAP ingestion. However, for late-presenting patients or after ingestion of very large overdoses, the efficacy of NAC is diminished. Thus, additional antidotes with an extended therapeutic window may be needed for these patients. Fomepizole (4-methylpyrazole), a clinically approved antidote against methanol and ethylene glycol poisoning, recently emerged as a promising candidate. In animal studies, fomepizole effectively prevented APAP-induced liver injury by inhibiting Cyp2E1 when treated early, and by inhibiting c-jun N-terminal kinase (JNK) and oxidant stress when treated after the metabolism phase. In addition, fomepizole treatment, unlike NAC, prevented APAP-induced kidney damage and promoted hepatic regeneration in mice. These mechanisms of protection (inhibition of Cyp2E1 and JNK) and an extended efficacy compared to NAC could be verified in primary human hepatocytes. Furthermore, the formation of oxidative metabolites was eliminated in healthy volunteers using the established treatment protocol for fomepizole in toxic alcohol and ethylene glycol poisoning. These mechanistic findings, together with the excellent safety profile after methanol and ethylene glycol poisoning and after an APAP overdose, suggest that fomepizole may be a promising antidote against APAP overdose that could be useful as adjunct treatment to NAC. Clinical trials to support this hypothesis are warranted.
Healthcare workers caring for coronavirus disease 2019 (COVID‑19) patients are at an increased risk for asevere acute respiratory syndrome coronavirus2 (SARS-CoV-2) infection. The aim of this seroepidemiological study was to evaluate the risk of infection for employees at atertiary care hospital.

Serological tests for antibodies against SARS-CoV‑2 were carried out in aprospective cohort of employees directly involved in the care of COVID‑19 patients every 2weeks from March to July 2020 (1st wave). Antibody status was examined again between December 2020 and February 2021 (2nd wave).

The seroprevalence of antibodies against SARS-CoV‑2 was 5.1% at the end of the study in February 2021. The cumulative incidence was 3.9% after amedian observation period of 261 days.

We observed alow risk of SARS-CoV‑2 infection comparable to that of the general population in the examined cohort of healthcare workers involved in the acute care of COVID‑19 patients under the applied hygiene and protective measures.

The optimal timing for removing urinary catheters is controversial for patients undergoing total hysterectomy. This study aimed to evaluate the optimal time for removing urinary catheters post-hysterectomy.

We searched multiple databases from inception till December 31, 2020, for all randomized trials evaluating the timing of catheter removal following hysterectomy. All studies were evaluated by two investigators independently depending on inclusion and exclusion criteria. Network meta-analysis (NMA) was conducted on the data using Stata 14.0 software.

A total of 12 articles involving 1814 patients were ultimately included. This study showed removing urinary catheters 12.1 to 24h (pooled OR = 2.67; 95% CI, 1.53‑4.67) and 36.1 to 48h (pooled OR = 8.11;95% CI, 3.78‑17.36) post-hysterectomy increased the risk of urinary tract infection (UTI) compared with immediate catheter removal. Timing of catheter removal in other groups following hysterectomy accompanied a reduced risk of urinary retention (UR) versus immediate catheter removal (P < 0.05). Removal of the urinary catheter from 36.1 to 48h was most likely to lead to UTI. The maximum SUCRA value of immediate catheter removal after hysterectomy was 99.3% for UR. Catheter removal 24.1 to 36h after hysterectomy was the best time for preventing UR.

Removal of the catheter immediately after hysterectomy may be the optimal time for preventing UTI with increased risk of UR, whereas removal time of the urinary catheters within 6h post-hysterectomy combined with postoperative urination monitoring might be more beneficial than other removal times following hysterectomy.

Some vasculitides occur preferentially in childhood, such as Kawasaki syndrome or immunoglobulin A (IgA) vasculitis, whereas others, such as giant cell arteritis, occur beyond the age of 50 years. Vasculitides occurring in childhood or adolescence and adulthood may have different phenotypes, different disease courses and outcomes depending on the age of manifestation. For example, those with Takayasu arteritis beginning in adolescence have different vascular involvement, a higher degree of systemic inflammation and a more aggressive course of disease than those with adult-onset disease. In contrast, IgA vasculitis is more severe in adults than in children. The causes for the age predilections and different age-dependent disease manifestations have not yet been clarified. The therapeutic principles are similar for vasculitides occurring in children or adolescents and adults. The first international evidence-based treatment recommendations are now available for juvenile vasculitides, although the evidence for certain forms of treatment is still very limited. The treatment of adult vasculitides can be guided by numerous national and international guidelines and recommendations. Many vasculitides carry a high risk of morbidity and mortality and the timely detection and treatment are therefore necessary. In this article, similarities and differences in the clinical presentations, treatment, courses and prognosis of vasculitides in children or adolescents and adults are discussed.
Radiological anatomical variations, measured by magnetic resonance imaging (MRI), were evaluated in patients with ipsilateral delayed endolymphatic hydrops (DEH) and unilateral Ménière's disease (MD). The role of anatomical variations in different subtypes of hydropic ear disease was investigated.

Twenty-eight patients with ipsilateral DEH, 76 patients with unilateral MD, and 59 control subjects were enrolled. The radiological indices included the distance between the vertical part of the posterior semicircular canal and the posterior fossa (MRI-PP distance) and the visibility of vestibular aqueduct (MRI-VA). selleck products These variations among patients with DEH, MD, and control subjects were compared. The correlation between radiological anatomical variations and clinical features or audio-vestibular findings was also examined.

(1) MRI-PP distance in the affected side of unilateral MD was shorter than that in ipsilateral DEH (Z =  - 2.481, p = 0.013) and control subjects (Z =  - 2.983, p = 0.003), while the difference of MRI-PP distance between the affected side of ipsilateral DEH and control subjects was not statistically significant (Z =  - 0.
