High flow nasal oxygen (HFNO) therapy has been widely used in intensive care units (ICU); however, its efficacy remains inconclusive. This systematic review and meta-analysis aimed to compare the efficacy of HFNO therapy with th at of alternative noninvasive oxygen therapies such as conventional oxygen therapy (COT) and noninvasive ventilation (NIV) in ICU.
A Pubmed, Embase, Web of Science, Cochrane Library database search was performed in March 2020.
The meta-analysis ultimately included 17 clinical studies. Compared with the overall effect of COT and NIV, HFNO was associated with a low incidence of pneumonia (95% CI 0.6-0.99,
=0.04) and improvement in lowest pulse oxygen saturation (SpO₂) during oxygenation (95% CI 0.02-1.61;
=0.04). However, no differences were detected in the following outcomes length of ICU stay, the rate of intubation or reintubation, mortality at day 28, hospital mortality, and SpO₂ at the end of oxygen therapy (all
>0.05).
In adult patients in ICU, HFNO may improve oxygenation and decrease pneumonia rate without affecting the length of ICU stay, intubation or reintubation rate, mortality, and SpO₂ at the end of oxygen therapy.

Herein, we report a patient with MM2-cortical-type sporadic CJD (MM2C-type sCJD) with long-term preservation of pharyngeal swallowing function using videofluoroscopic (VF) examination of swallowing. A 55-year-old woman was admitted to hospital because of dyscalculia and memory disturbance 3 years after the onset of these symptoms. Neurological examination revealed dementia, extrapyramidal signs, and delusion. Diffusion-weighted MRI revealed bilateral hyperintensity in the basal ganglia and frontal, temporal, and parietal cortices. read more No mutation with the methionine homozygote at codon 129 was found on PRNP gene analysis. VF was performed 68 months after the onset. Although bolus transport from the oral cavity to the pharynx worsened, the pharyngeal swallowing function was preserved even 68 months after onset. Serial MRI examinations revealed no apparent atrophy of the brainstem. Single photon emission computed tomography revealed that the regional cerebral blood flow in the brainstem was preserved. These findings suggest that pseudobulbar palsy is the pathophysiology underlying dysphagia in long-term survivors of MM2C-type sCJD, probably owing to preserved brainstem function even in a state of akinetic mutism.
Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive technique showing improvement effects on Parkinson's disease (PD). Multiple microRNAs (miRs) are dys-expressed during the progression of PD. In the current study, the potential involvement of miRs in the anti-PD effects of rTMS was explored.
PD symptoms were induced in mice with 6-OHDA. The expression profile of miRs influenced by rTMS in PD mice was detected by microarray technique and validated by RT-qPCR detection. The PD mice were treated with rTMS and the changes in cognitive behaviors, substantia nigra neuron number, brain histology, and Aβ
level were detected. The activity of miR-409-3p/PDHB axis was also detected to preliminarily explain the interaction between miRs and rTMS.
The detection of microarray showed that 266 miRs were dys-expressed in PD mice after the administration of rTMS, including 101 up-regulated ones and 146 down-regulated ones. With validation by RT-qPCR detection, miR-409-3p was selected for subsequent assays. Administrations of rTMS improved cognitive behaviors of mice, increased neuron number, and attenuated brain injuries induced by 6-OHDA. The cerebrospinal fluid (CSF) level of Aβ
was induced, while the brain level of Aβ
was suppressed by rTMS. Regarding miR-409-3p/PDHB axis, rTMS administrations suppressed miR-409-3p level and increased the expression of PDHB.
Administrations of rTMS showed considerable protective effects on brain tissues against PD-induced injuries, which was associated with the changes in miR levels. The current study demonstrated that the inhibition of miR-409-3p by rTMS contributed to the attenuation of PD by inducing PDHB.

Currently, at least ten COVID-19 vaccines have been authorized under emergency authorization. However, these vaccines still face many challenges.Areas covered This study reviews the concept and mechanisms of trained immunity induced by the Bacille Calmette Guérin (BCG) vaccine and identifies questions that should be answered before the BCG vaccine could be used to combat COVID-19 pandemic. Moreover, we present for the first time the details of current BCG vaccine clinical trials, which are underway in various countries, to assess its effectiveness in combating the COVID-19 pandemic. Finally, we discuss the challenges of COVID-19 vaccines and opportunities for the BCG vaccine. The literature was found by searching the PubMed (https//pubmed.ncbi.nlm.nih.gov/), Web of Science (https//www.webofknowledge.com), Embase (https//www.embase.com), and CNKI (https//www.cnki.net/) databases. The date was set as the default parameter for each database.Expert opinion The advantages of the BCG vaccine can compensate for the shortcomings of other COVID-19 vaccines. If the efficacy of the BCG vaccine against COVID-19 is confirmed by these clinical trials, the BCG vaccine may be essential to resolve the challenges faced by COVID-19 vaccines.Aging impairs visual associative memories. Up to date, little is known about whether aging impairs auditory associative memories. Using the head-related-transfer function to induce perceived spatial locations of auditory phonemes, this study used an audiospatial paired-associates-learning (PAL) paradigm to assess the auditory associative memory for phoneme-location pairs in both younger and older adults. Both aging groups completed the PAL task with various levels of difficulty, which were defined by the number of items to be remembered. The results showed that compared with younger participants' performance, older participants passed fewer stages and had lower capacity of auditory associative memory. For maintaining a single audiospatial pair, no significant behavioral differences between the two aging grous werefound. However, when multiple sound-location pairs were required to be remembered, older adults made more errors and demonstrated a lower working memory capacity than younger adults. Our study indicates aging impairs audiospatial associative learning and memory.
Ongoing leadership development is essential for academic health center faculty members to respond to increasing environmental complexity. At the George Washington University School of Medicine and Health Sciences, an 8-month program, based on Conger's leadership development approach emphasizing conceptual understanding, skill building, feedback and personal growth was offered to mid-level faculty charged with developing educational programs, clinical services, and/or research initiatives. We studied how specific learning methods catering to different learning approaches contributed to improving leadership competencies.
Session and program evaluations, participant interviews, mentor surveys, and supervisor interviews were used for data collection. Themes were identified through open coding with use of constant comparative methods to help find patterns in the data.
Readings and classroom modules provided a broadened, holistic understanding of leadership; role plays and action plans helped participants apply and practice leadership skills; self-assessments and feedback from peers and mentors provided specifics for focusing development efforts; and personal growth exercises provided opportunities to reflect and consider fresh perspectives. Anchoring learning methods around a real-time project led to improved leadership competencies and personal confidence as reported by participants, supervisors and mentors.
A faculty leadership development program that integrates understanding, skill building, feedback and personal growth and connects multiple learning methods can provide the synergy to facilitate behavior change and organizational growth.

Its secure forecast is of the utmost importance for all health prevention strategies and regulations.Areas covered We surveyed several types of alternative, animal-free approaches ((quantitative) structure-activity relationship (Q)SAR, read-across, Adverse Outcome Pathway, Integrated Approaches to Testing and Assessment) for genotoxicity prediction within the needs of regulatory frameworks, putting special emphasis on data quality and uncertainties issues.Expert opinion (Q)SAR models and read-across approaches for in vitro bacterial mutagenicity have sufficient reliability for use in prioritization processes, and as support in regulatory decisions in combination with other types of evidence. (Q)SARs and read-across methodologies for other genotoxicity endpoints need further improvements and should be applied with caution. It appears that there is still large room for improvement of genotoxicity prediction methods. Availability of well-curated high-quality databases, covering a broader chemical space, is one of the most important needs. Integration of in silico predictions with expert knowledge, weight-of-evidence-based assessment, and mechanistic understanding of genotoxicity pathways are other key points to be addressed for the generation of more accurate and trustable results.
The introduction of the full-thickness resection device (FTRD) allowed resection of difficult adenomas in the duodenum and colorectum with non-lifting. The main limitation of this endoscopic technique is the lesion size. We describe a hybrid approach combining endoscopic mucosal resection (EMR) and FTRD in a cohort of 17 patients to reduce tumor size and enable full-thickness resection.
Retrospective analysis from data of 17 patients who underwent hybrid EMR-FTRD for large adenomas in the colorectum at our institution. Technical success, histological confirmation of margin-free resection and adverse advents were studied.
16 of 17 (94.1%) lesions could be resected macroscopically complete with confirmed full-thickness resection. Histological work-up of the full-thickness specimens showed free lateral margins in 13 patients (76.4%), unclear margins in two patients (11.8%) and positive margins in two patients (11.8%). There were no immediate perforation or major bleeding, however one patient showed a stenosis after resection in the follow-up endoscopy.
