The protection of health care workers from nosocomial infection is a paramount consideration in the current pandemic involving severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Not only is prevention of viral transmission the most effective means to lessen the public health impact of coronavirus disease 2019 (COVID-19), but also both quarantine and illness – that disproportionately affect health care workers – have devastating effects on the ability of hospitals to adequately care for increased patient loads.

Many drugs are effective systemically, but slow onset of non-intravenous routes of administration may limit their clinical utility. While anesthesiologists usually have intravenous (IV) access for drug delivery, other healthcare professionals in less controlled situations such as acute crises in the emergency room, critical care settings, or urgent needs in the community, may need non-invasive drug delivery [1].

Background: Breast cancer remains a major global health burden despite therapeutic advances, necessitating further innovations to address persistent challenges like therapeutic resistance, adverse effects, and mortality in subgroups. Emerging technologies offer promising opportunities in this regard through data-driven, precise, and personalized approaches.

Microsurgical training is an asset for deployed military orthopaedic surgeons who frequently treat hand or nerve injuries in the field.

HELLP syndrome (hemolysis, elevated liver blood tests and low platelets) is a serious complication in pregnancy characterized by hemolysis, elevated liver enzymes and low platelet count occurring in 0.2 to 0.6% of all pregnancies and in 10–20% of cases with severe preeclampsia

The incorporation of patient-reported outcomes (PROs) is essential for assessing whether a cancer treatment enhances overall patient well-being, beyond merely extending survival. This scoping review aimed to identify and analyze the use of PROs in ovarian cancer clinical trials.

Primary myelofibrosis (PMF) is a type of myeloproliferative neoplasm (MPN) that portends a poor prognosis and has limited options for treatment. PMF is often driven by clonal mutations in one of three genes that regulate the JAK-STAT signaling pathway, leading to hyperactivation of this signaling pathway and over-proliferation of megakaryocytes (MKs) and their precursors. PMF presents with debilitating symptoms such as splenomegaly and weight loss.

Examining BRCA mutations in preoperative breast cancer patients is very important when selecting a surgical procedure. Although there are advantages and disadvantages associated with knowing about the presence of genetic mutations, including for the patient’s family, there are many benefits for the patient. BRCA genetic testing should be recommended for patients who are strongly suspected of being positive for a BRCA mutation. 

Liver masses account for 5 to 6% of pediatric cancer, which includes hepatoblastoma (HBL) along with rare cases of hepatocellular carcinoma (HCC). The most dangerous form of pediatric liver cancer is aggressive HBL, which can be characterized by chemo-resistance and multiple nodules or metastases at diagnosis, all correlating with worse clinical prognosis. Despite intensive studies and a significant improvement in overall outcomes, very little is known about the key molecular pathways which determine the aggressiveness of pediatric liver cancer.

Background: lack of knowledge and awareness of COVID-19 and radiation safety among healthcare professionals will adversely affect their health and the patients’ safety due to unnecessary radiation exposure and rapid spread of COVID-19. The purpose of this study is to evaluate the knowledge and the awareness of both domains; COVID-19 and radiation awareness in one survey study. 

The craniovertebral junction is unique and the most complex of the axial skeleton in multiple aspects; embryology, anatomy, pathology and kinematics. A surgical physiological approach to management of its abnormalities was instituted at the University of Iowa Hospitals & Clinics (UIHC) in 1977 and has been the accepted treatment algorithm worldwide.

The COVID-19 pandemic presents unprecedented challenges for anesthesia professionals and their surgical patients. Beyond managing infection risk, positive COVID-19 surgical patients add additional challenges to their perioperative care, where its perioperative risk are superimposed onto an already baseline anesthesia risk in real-time with an unknown and unpredictable fashion.

Anesthesia and surgical interventions may induce cognitive impairments, such as postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) [1]. These dysfunctions particularly affect the elderly population [2] and increase morbidity and mortality thus representing a major burden for the healthcare system [1].

This commentary focuses on two recent publications showing deregulation of the transcription factor Slug/Snail2 and TGF-β function in primary bronchial basal/progenitor cells of patients with Chronic Obstructive Pulmonary Disease (COPD) and the impact on proliferation and the expression of genes involved in stem cell maintenance. We discuss the molecular mechanisms related to the exhaustion of airway basal stem/progenitor cells in tobacco smoke-induced COPD, as well as putative links between COPD and lung cancer at the molecular level.

Cancer biology involves complex dynamics and interactions between cells and the tissue environment. Mathematical modeling and computer simulation can provide a powerful instrument for considering this complexity. Agent-based modeling is a particular discrete hybrid modeling method.

Radiation therapy (RT) is one of the pillars of locally advanced head and neck cancer (HNSCC) treatment in combination with cisplatin or epidermal growth factor receptor inhibitors. Despite a very high local tumor control rate, approximately 50% of patients with locally advanced disease will develop a recurrence.

The effects of COVID-19 have been of increasing interest in all fields of medicine after the pandemic, especially considering the important impact and incidence of patients infected with coronavirus. Numerous studies have reported the vast clinical implications related to permanent organ and tissue damage after infection and long COVID. 

Wolf-Hirschhorn Syndrome (WHS, OMIM 194190) is a rare congenital malformation syndrome caused by a partial deletion of the short arm (p) of chromosome 4. It is characterized by “Greek warrior helmet” facies, central nervous system disorders including seizures and structural defects, and intrauterine growth restriction, among numerous other systemic anomalies.

Diabetic Retinopathy (DR) is a leading cause of blindness in the U.S. However, not much is known of underlying molecular mechanism and how oxidative stress contributes to its development. In the present study, we investigated the involvement of TGFβ signaling pathway on the effect of oxidative stress on VEGF secretion and viability of retinal cells. VEGF is the hallmark that exacerbates DR progression in prolonged diabetes. Some major concerns that have arisen are the underlying effects of antioxidants in elevating VEGF secretion in diabetes.

Transient receptor potential (TRP) family is a large superfamily of widely expressed ion channels. In recent years, several studies have been conducted on the mechanism of action of TRP. However, studies on the role of TRP in liver diseases are limited. In fact, TRP plays a vital role in the progression of many liver diseases, such as hepatic fibrosis, hepatocellular carcinoma, alcoholic fatty liver disease, and nonalcoholic fatty liver disease.
