Materials And Methods: We analyzed CT imaging of 350 female and 350 male patients.

A Tale of Two Rings: The Need for Informed Consent.

Over the past 85 years, the mission of the FDA's Center for Device and Radiologic Health has been to provide safe medical devices for the US consumer, and to adapt the regulatory standards to meet the needs of the rapidly evolving medical device industry. This brief report is the historical account of two investigational devices dating back to 2006, the devices never receiving FDA approval for use in patients during a clinical trial, and the patients never received informed consent.

Presence of Heavy Metals in Vegetables Irrigated with Wastewater-Impacted Rivers and Its Health Risks in Ethiopia: Systematic Review.

Background: Vegetables play critical role in human nutrition and overall health. However, consumption of vegetables cultivated through wastewater-impacted river can be source of potentially toxic heavy metals, which can cause detrimental health effects when their concentration exceeds the recommended maximum levels. Despite growing body of evidence highlighting the dangers associated with heavy metal accumulation in vegetables, there remains critical gap in systematic assessments within Ethiopian context.

Identification of immunostimulatory activities and active compounds from sequentially extracted fractions of rhizosphere fungal fermentation broth of Koidz. rhizomes.

Introduction: Pharmacological studies have shown that the rhizome of Atractylodes macrocephala Koidz. (Compositae), commonly known as atractylodes macrocephala rhizome (AMR), can modulate immunity. Nevertheless, its resources have been largely depleted, and the pharmacological activity of artificial AMR is relatively modest.

Hydrogen storage properties of TiFe-based composite with Ni addition.

This paper presents the preparation of the parental experimental alloy, featuring a standard composition of TiYZrFeNiMn, via the vacuum induction melting technique. Subsequently, the TiYZrFeNiMn alloy, with an addition of 2 wt% Ni, underwent mechanical ball milling to yield a TiFe-based composite for experimental purposes. The results of the experimental tests indicate that the composite alloy's phase composition comprises the TiFe primary phase, with a minor quantity of ZrMn phase segregated on the surface of the primary TiFe phase, as well as Ni phase.

Comparative evaluation of oral premedication with clonidine and metoprolol on surgical field conditions and intraoperative hemodynamics during functional endoscopic sinus surgery.

This study was aimed to compare the efficacy of oral clonidine versus oral metoprolol as premedicants regarding surgical field condition and controlled hypotension in patients undergoing FESS.

Material And Methods: Sixty-eight patients of American Society of Anesthesiologists (ASA) physical status (PS) I and II aged 18-60 years, of both genders, scheduled for FESS under general anesthesia were randomly allocated in two groups.

Efficacy of ultrasound-guided suprazygomatic maxillary nerve block on emergence agitation and postoperative analgesia after septorhinoplasty: A prospective randomized trial.

Background And Aims: Emergence agitation (EA) is frequently encountered following nasal surgeries, and postoperative pain is a significant contributing element. We aimed to assess the role of suprazygomatic maxillary nerve (MN) block (SMB) guided by ultrasound (US) in lowering EA incidence and enhancing analgesia quality in septorhinoplasty cases.

Material And Methods: Sixty cases aged 18-60 years, of both genders, categorized by the American Society of Anesthesiologists (ASA) I-II and listed for septorhinoplasty, were randomized to receive general anesthesia (GA) with either no block (the control group) or combined with bilateral US-guided SMB (the SMB group).

Intraosseous basivertebral nerve ablation: A 5-year pooled analysis from three prospective clinical trials.

Background: Vertebrogenic pain is a documented source of anterior column chronic low back pain (CLBP) that stems from damaged vertebral endplates. Nociceptive signals are transmitted by the basivertebral nerve (BVN) and endplate damage is observed as Type 1 or Type 2 Modic changes (MC) on magnetic resonance imaging (MRI). The clinical impact and safety of intraosseous radiofrequency ablation of the BVN (BVNA) for the treatment of vertebrogenic pain has been demonstrated in three prospective clinical trials (two randomized and one single-arm study).

Causal Discovery with Generalized Linear Models through Peeling Algorithms.

This article presents a novel method for causal discovery with generalized structural equation models suited for analyzing diverse types of outcomes, including discrete, continuous, and mixed data. Causal discovery often faces challenges due to unmeasured confounders that hinder the identification of causal relationships. The proposed approach addresses this issue by developing two peeling algorithms (bottom-up and top-down) to ascertain causal relationships and valid instruments.

Dataset and analysis of automated and manual methods to differentiate wide QRS complex tachycardias.

The differentiation of wide complex tachycardias (WCTs) into ventricular tachycardia (VT) and supraventricular wide tachycardia (SWCT) via 12-lead ECG (electrocardiogram) interpretation is a crucial yet demanding clinical task. Decades of research have been dedicated to simplifying and improving this differentiation via manual algorithms. Despite such research, the effectiveness of such algorithms still remains limited, primarily due to reliance on user expertise.

Use of Complementary and Integrative Medicine Among Low-Income Persons With Mental Health Disorders.

Objective: To evaluate the use of complementary and integrative medicine (CIM) among a low-income population with mental health diagnoses and to assess differences in social determinants of health (SDOH) on the basis of CIM use.

Patients And Methods: We surveyed patients with mental health diagnoses and/or substance use disorders during outpatient evaluations between August 11, 2020, and November 18, 2021, at a community behavioral health center in Rochester, MN. We measured knowledge of current CIM, interest in future use of CIM, and SDOH.

Innovation in Medical Student Education: Implementing Clerkships in 3D Printing, Virtual Reality, and Medical Device Development.

Medical devices, 3D printing, and virtual reality are increasingly integral components of medical practice to improve patient outcomes. Physicians engage directly with clinical challenges but may need more training to develop innovations that prioritize patient-centered design. To bridge the gap, hands-on clerkships were implemented to develop foundational skills related to emerging medical technologies.

Enhancing immune response and survival in hepatocellular carcinoma with novel oncolytic Jurona virus and immune checkpoint blockade.

Members of the genus including Jurona virus (JURV) have emerged as promising immunotherapeutic agents, characterized by their tumor selectivity, fast kinetics, low seroprevalence, and minimal toxicity in humans. Here, we demonstrate that the administration of JURV leads to tumor regression in both hepatocellular carcinoma (HCC) xenograft and syngeneic models. Furthermore, our findings indicate that combining JURV and anti-PD-1 therapy reduced tumor burden and improved survival rates over JURV or anti-PD-1 alone in an orthotopic HCC model.
