Aeromedical Implications of Long-Term COVID-19 Sequelae.

While many COVID-19 studies focus on acute effects of the infection, few examine the intermediate and long-term sequelae of the illness. Studies have shown that a good portion of patients have chronic effects in several body systems for several months or longer. Such effects can potentially adversely impact pilot performance in flight.

Cost Implications of Using Carbetocin Injection to Prevent Postpartum Hemorrhage in a Canadian Urban Hospital.

Objective: Recent World Health Organization (WHO) recommendations regarding uterotonics for the prevention of postpartum hemorrhage (PPH) state that carbetocin should be considered a first-line prophylactic agent for all births where its cost is comparable to other effective uterotonics. This study evaluated whether a room temperature stable formulation of carbetocin met this recommendation in a Canadian urban hospital setting.

Methods: A decision tree model was developed to assess the financial implications of replacing oxytocin with carbetocin as a first-line prophylactic agent for PPH prevention in a Greater Toronto Area (GTA) hospital.

Multiple E-2D Hawkeye Aircrew with Neurocognitive Symptoms During a Single Over-Pressurization Episode.

Increased frequencies of physiological episodes have been a significant concern for Naval Aviation for the last several years. These include several aircraft platforms, but no previously documented E-2D Hawkeye events. This report documents an episode in an E-2D, with multiple aircrew affected at the same time.

Racial discrimination, ethnic-racial socialization, and cultural identities among Asian American youths.

Objectives: This study investigates whether and how racial discrimination is associated with ethnic-racial socialization in the family and how distinct aspects of ethnic-racial socialization influence children's ethnic and American identity among Filipino American and Korean American families.

Method: The data are obtained from the Midwest Longitudinal Study of Asian American Families Project ( = 1,580; 379 Filipino American youths and 377 parents, and 410 Korean American youths and 414 parents; of youths = 15.01).

Measuring cardiac index with a focused cardiac ultrasound examination in the ED.

Objectives: Noninvasive technology may assist the emergency department (ED) physician in determining the hemodynamic status in critically ill patients. The objective of our study was to show that ED physicians can accurately measure cardiac index (CI) by performing a bedside focused cardiac ultrasound examination.

Methods: A convenience sample of adult subjects were prospectively enrolled.

Effect of surface composition on the adsorption of photosystem I onto alkanethiolate self-assembled monolayers on gold.

We have used self-assembled monolayers (SAMs) prepared from omega-terminated alkanethiols on gold to generate model surfaces and examine the effect of surface composition on the adsorption of Photosystem I (PSI), stabilized in aqueous solution by Triton X-100. Triton-stabilized PSI adsorbs to high-energy surfaces prepared from HO- and HO2C-terminated alkanethiols but does not adsorb to low-energy surfaces. The inhibition of PSI adsorption at low-energy surfaces is consistent with the presence of a layer of Triton X-100 that adsorbs atop the hydrophobic SAM and presents a protein-resistant poly(ethylene glycol) (PEG) surface.

CDX2 co-localizes with liver-intestine cadherin in intestinal metaplasia and adenocarcinoma of the stomach.

CDX2 and liver-intestine (LI)-cadherin are intestine-specific markers and both are physiologically expressed in the small intestine and colon. Recent studies have demonstrated that CDX2 regulates LI-cadherin gene (CDH17) expression in colorectal cancer. The present study investigated the relationship of CDX2 and LI-cadherin expression in gastric cancer.

Overexpression of LI-cadherin in gastric cancer is associated with lymph node metastasis.

Gastric cancer remains the second leading cause of cancer deaths worldwide. Patients usually present late with local invasion or metastatic diseases. The present study investigated the expression level of liver-intestine cadherin (LI-cadherin) by RT-PCR and its correlation with clinicopathological data in 71 pairs of tumor and non-cancerous gastric mucosa.

Definitions of "respiratory depression" with intrathecal morphine postoperative analgesia: a review of the literature.

Purpose: To review the postoperative intrathecal morphine (ITM) analgesia literature for their definitions of "respiratory depression" (RD).

Source: Medline (1966 - June Week 5 2001) and reference lists were searched for original studies involving bolus-dose ITM for postoperative analgesia, which used "respiratory depression" or similar terms.

Principle Findings: The search identified 209 studies.

Soluble E-cadherin is an independent pretherapeutic factor for long-term survival in gastric cancer.

Purpose: To evaluate whether pretherapeutic serum soluble E-cadherin is an independent factor predicting long-term survival in gastric cancer. Gastric cancer remains the second leading cause of cancer-related deaths in the world, but a satisfactory tumor marker is currently unavailable for gastric cancer. Soluble E-cadherin has recently been found to have prognostic value in gastric cancer.
