This review aims to provide an up-to-date evaluation of COVID-19 vaccine hesitancy among the public in the Gulf Cooperation Council countries. We searched the PubMed and SCOPUS databases for manuscripts published on vaccine hesitancy and/or acceptance among the public in GCC countries up till April 1st, 2022. Forty-nine studies met the inclusion criteria and were reviewed. The average vaccine hesitancy rate across GCC countries was 43%. Concerns about vaccine safety (n = 32) and effectiveness (n = 26) were most frequently associated with hesitancy. Being male (n = 25) and having positive behavior regarding the influenza vaccine or vaccines in general (n = 22) were most frequently associated with acceptance. Collaborative efforts of governments, academic bodies, and the media to provide evidence of vaccines' effectiveness throughout history and strictly manage the spread of the vaccine safety-related rumors are warranted.

Pediatric patients with diffuse intrinsic pontine glioma (DIPG) have a poor prognosis, with a median survival of less than 1 year. Oncolytic viral therapy has been evaluated in patients with pediatric gliomas elsewhere in the brain, but data regarding oncolytic viral therapy in patients with DIPG are lacking.

We conducted a single-center, dose-escalation study of DNX-2401, an oncolytic adenovirus that selectively replicates in tumor cells, in patients with newly diagnosed DIPG. The patients received a single virus infusion through a catheter placed in the cerebellar peduncle, followed by radiotherapy. The primary objective was to assess the safety and adverse-event profile of DNX-2401. The secondary objectives were to evaluate the effect of DNX-2401 on overall survival and quality of life, to determine the percentage of patients who have an objective response, and to collect tumor-biopsy and peripheral-blood samples for correlative studies of the molecular features of DIPG and antitumor immune responses.

with DIPG resulted in changes in T-cell activity and a reduction in or stabilization of tumor size in some patients but was associated with adverse events.

Intratumoral infusion of oncolytic virus DNX-2401 followed by radiotherapy in pediatric patients with DIPG resulted in changes in T-cell activity and a reduction in or stabilization of tumor size in some patients but was associated with adverse events.

A manner by which diprovocims can be functionalized without impacting hTLR1/TLR2 activity is detailed, permitting future linkage to antigenic, targeting, or delivery moieties. Improvements in both potency and its low efficacy in the murine system were also achieved, permitting more effective use in animal models while maintaining the hTLR1/TLR2 activity. The prototypical member diprovocim-X exhibits the excellent potency/efficacy of diprovocim-1 in human cells, displays substantially improved potency/efficacy in mouse macrophages, and serves as an adjuvant in mice when coadministered with a nonimmunogenic antigen, indicating stimulation of the adaptive as well as innate immune response.A new oxygen-deficient perovskite Ba3LiNb2O8.5□0.5 was synthesized via a conventional solid-state route and compared to the already known perovskite Ba3Li0.75Nb2.25O9. The structure of Ba3LiNb2O8.5□0.5 was investigated by means of X-ray and neutron diffraction, TEM, NMR, and XPS. The study of its thermal behavior revealed an unexpected color change when heated to 1400 °C in a sealed platinum tube, with conservation of the initial X-ray structure. First-principles calculations have been performed in order to better understand these observations. The geometry optimizations and the optical spectra simulations highlight the role of both Nb/Li distribution and oxygen-vacancy location.

Acute respiratory distress syndrome (ARDS) represents the most severe course of COVID-19 (caused by the SARS-CoV-2 virus), usually resulting in a prolonged stay in an intensive care unit (ICU) and high mortality rates. Despite the fact that most affected individuals need invasive mechanical ventilation (IMV), evidence on specific ventilation strategies for ARDS caused by COVID-19 is scarce. Spontaneous breathing during IMV is part of a therapeutic concept comprising light levels of sedation and the avoidance of neuromuscular blocking agents (NMBA). This approach is potentially associated with both advantages (e.g. a preserved diaphragmatic motility and an optimised ventilation-perfusion ratio of the ventilated lung), as well as risks (e.g. a higher rate of ventilator-induced lung injury or a worsening of pulmonary oedema due to increases in transpulmonary pressure). As a consequence, spontaneous breathing in people with COVID-19-ARDS who are receiving IMV is subject to an ongoing debate amongst intensivists people with COVID-19. Additionally, studies should aim to clarify whether treatment effects differ between people with SARS-CoV-2-induced ARDS and people with non-SARS-CoV-2-induced ARDS.

Health care providers' knowledge and attitudes about vaccines are important determinants of their own vaccine uptake, their intention to recommend vaccines, and their patients' vaccine uptake. This qualitative study' objective was to better understand health care providers' vaccination decisions, their views on barriers to COVID-19 vaccine acceptance and proposed solutions, their opinions on vaccine policies, and their perceived role in discussing COVID-19 vaccination with patients.

Semi-structured interviews on perceptions of COVID-19 vaccines were conducted with Canadian health care providers (N = 14) in spring 2021. A qualitative thematic analysis using NVivo was conducted.

Participants had positive attitudes toward vaccination and were vaccinated against COVID-19 or intended to do so once eligible (two delayed their first dose). Only two were actively promoting COVID-19 vaccination to their patients; others either avoided discussing the topic or only provided answers when asked questions. Participanaining to feel confident in engaging in vaccine discussions with their patients.Adhesion of a liquid droplet to a solid surface is a result of solid surface interactions with surrounding fluids, affected by its wettability and morphology. Unfortunately, the direct measurements of adhesion forces are rarely reported in the scientific literature, especially for solids with curvatures. In this study, by using a high-sensitivity microelectronic mechanical balance which vertically deposits and then pulls liquid droplets, the spreading and adhesion forces for water and ethylene glycol droplets on spherical surfaces of polyethylene terephthalate (PET) with radii of curvature from 2 to 8 mm were recorded. Results show that the surface curvature does not affect the advancing and most-stable contact angles but affects the extent of spreading and maximum adhesion forces. The solid surface curvature affects both surface tension and Laplace pressure forces at the spreading point, whereas it mainly affects the Laplace pressure force at the maximum adhesion point.This study compares the effects of two trance texts using different language patterns, i.e., modern trance language (MTL) characterized by indirect suggestions as well as narrative style and traditional trance language (TTL) found in traditional societies (e.g., Navajo, San, Aranda aborigines, etc.) that uses multiple repetitions along with narrative sequences. The Phenomenology of Consciousness Inventory (PCI) was used to evaluate the effects of both texts regarding cognition, emotion, physical experience, and trance depth. In this randomized controlled online study, 178 participants were assigned either to the MTL group or to the TTL group. The PCI and other tests (e.g. Positive and Negative Affect Schedule, State-Trait-Anxiety Inventory) were presented to the participants before and after listening to the hypnosis audio of the respective trance text. There were no significant differences between groups concerning trance depth, emotional, and physical experience. However, on the cognitive-imaginative level it was shown that the TTL group experienced more imaginations (PCI-subdimension "visual imagery," p = .009, d = 0.38) and less cognitive activity (PCI-subdimension "inner dialogue," p = .002, d = 0.40) than the MTL group. The results indicate that TTL increases imagery and decreases cognitive activity to a larger extent than MTL. This further indicates the potential of TTL to facilitate more vivid and intensive trance experiences.To report clinical and radiographic outcomes of primary THA using three-dimensional (3D) image-based custom stems. This systematic review was performed according to PRISMA guidelines and registered with PROSPERO (CRD42020216079). A search was conducted using MEDLINE, Embase and Cochrane. Clinical studies were included if they reported clinical or radiographic outcomes of primary THA using 3D image-based custom stems. Studies were excluded if specific to patients with major hip anatomical deformities, or if not written in English. Fourteen studies were eligible for inclusion (n = 1936 hips). There was considerable heterogeneity in terms of manufacturer, proximal geometry, coating and length of custom stems. Revision rates ranged from 0% to 1% in the short-term, 0% to 20% in the mid-term, and 4% to 10% in the long-term, while complication rates ranged from 3% in the short-term, 0% to 11% in the mid-term and 0% to 4% in the long-term. Post-operative Harris hip scores ranged from 95 to 96 in the short-term, 80 to 99 in the mid-term, and 87 to 94 in the long-term. Radiographic outcomes were reported in eleven studies, although none reported 3D implant sizing or positioning, nor compared planned and postoperative hip architecture. Primary THA using 3D image-based custom stems in unselected patients provides limited but promising clinical and radiographic outcomes. Despite excellent survival, the evidence available in the literature remains insufficient to recommend their routine use. Future studies should specify proximal geometry, length, fixation, material and coating, as well as management of femoral offset and anteversion. The authors propose a classification system to help distinguish between custom stem designs based primarily on their proximal geometry and length.
