Ultrasound-guided Femoral - Sciatic Nerve Block for Lower Limb Long Bone Fractures.

Background: Fractures of the long bones in the lower limbs are injuries that cause severe to extremely severe pain, posing risks to the patient's circulation, respiration, and even life. Pain management for patients with lower limb long bone fractures in the emergency department is critically important.

Objective: This study aimed to evaluate the feasibility of ultrasound-guided femoral and sciatic nerve blocks in patients with lower limb long bone fractures in the emergency department (ED).

Hyperornithinemia-Hyperammonemia-Homocitrullinuria Syndrome in Vietnamese Patients.

: Hyperornithinemia-hyperammonemia-homocitrullinuria syndrome (HHH; OMIM 238970) is one of the rare urea cycle disorders. Ornithine carrier 1 deficiency causes HHH syndrome, characterized by failure of mitochondrial ornithine uptake, hyperammonemia, and accumulation of ornithine and lysine in the cytoplasm. The initial presentation and time of diagnosis in HHH highly varies.

Propofol TCI or sevoflurane anesthesia without muscle relaxant for thoracoscopic thymectomy in myasthenia gravis patients: a prospective, observational study.

Background: Myasthenia gravis (MG) patients interact unpredictably with anesthetic agents, including neuromuscular blocking agents. Here, we investigate the effectiveness of general anesthesia without muscle relaxants using either propofol via target-controlled infusion systems (TCI) or sevoflurane in MG patients undergoing thoracoscopic thymectomy.

Methods: This prospective, open-label, observational study was conducted in a university hospital.

The Ca channel ORAI1 is a regulator of oral cancer growth and nociceptive pain.

Oral cancer causes pain associated with cancer progression. We report here that the function of the Ca channel ORAI1 is an important regulator of oral cancer pain. was highly expressed in tumor samples from patients with oral cancer, and ORAI1 activation caused sustained Ca influx in human oral cancer cells.

Calcitonin Related Polypeptide Alpha Mediates Oral Cancer Pain.

Oral cancer patients suffer pain at the site of the cancer. Calcitonin gene related polypeptide (CGRP), a neuropeptide expressed by a subset of primary afferent neurons, promotes oral cancer growth. CGRP also mediates trigeminal pain (migraine) and neurogenic inflammation.

Pattern and perceived changes in quality of life of Vietnamese medical and nursing students during the COVID-19 pandemic.

Background: The COVID-19 pandemic and governments' response lead to dramatical change in quality of life worldwide. However, the extent of this change in Vietnamese medical and nursing students has not been documented.

Objectives: The study aims to describe the quality of life and changes in quality of life of medical and nursing students during the COVID-19 pandemic and examine the association of quality of life and changes in quality of life with fear of COVID-19 and other socio-economic and demographic factors.

Peroxisome proliferator-activated receptor gamma agonist ELB00824 suppresses oxaliplatin-induced pain, neuronal hypersensitivity, and oxidative stress.

Chemotherapy-induced neuropathic pain (CINP) is a debilitating and difficult-to-treat side effect of chemotherapeutic drugs. CINP is marked with oxidative stress and neuronal hypersensitivities. The peroxisome proliferator-activated receptor gamma (PPARγ) is a transcription factor that regulates genes involved in oxidative stress and inflammation.

Oral Cancer Cells Release Vesicles that Cause Pain.

Oral cancer pain is attributed to the release from cancers of mediators that sensitize and activate sensory neurons. Intraplantar injection of conditioned media (CM) from human tongue cancer cell line HSC-3 or OSC-20 evokes nociceptive behavior. By contrast, CM from noncancer cell lines, DOK, and HaCaT are non-nociceptive.

Cathepsin S Evokes PAR-Dependent Pain in Oral Squamous Cell Carcinoma Patients and Preclinical Mouse Models.

Oral squamous cell carcinoma (SCC) pain is more prevalent and severe than pain generated by any other form of cancer. We previously showed that protease-activated receptor-2 (PAR) contributes to oral SCC pain. Cathepsin S is a lysosomal cysteine protease released during injury and disease that can activate PAR.

Legumain Induces Oral Cancer Pain by Biased Agonism of Protease-Activated Receptor-2.

Oral squamous cell carcinoma (OSCC) is one of the most painful cancers, which interferes with orofacial function including talking and eating. We report that legumain (Lgmn) cleaves protease-activated receptor-2 (PAR) in the acidic OSCC microenvironment to cause pain. Lgmn is a cysteine protease of late endosomes and lysosomes that can be secreted; it exhibits maximal activity in acidic environments.

Oncogenes overexpressed in metastatic oral cancers from patients with pain: potential pain mediators released in exosomes.

Oral cancer patients experience pain at the site of the primary cancer. Patients with metastatic oral cancers report greater pain. Lack of pain identifies patients at low risk of metastasis with sensitivity = 0.

Factors associated with antenatal depression among pregnant women in Vietnam: A multisite cross-sectional survey.

This study aimed to describe the status of antenatal depression and its associated factors among pregnant women in Vietnam. A cross-sectional study was conducted in four obstetric hospitals in Vietnam from January to September 2019. A total of 1260 pregnant women were interviewed using a structured questionnaire.

Comparison of Novel, Bach Mai Boston Tool (BBT) and the Patient-Generated Subjective Global Assessment (PG-SGA) for Oncology Inpatients.

Oncology inpatients are at high risk of malnutrition. Identification of at risk patients by nutrition screening requires a practical and easy to use tool. The aim of this study was to determine the validity of the Bach Mai Boston Tool (BBT) compared to a 'gold standard' full nutrition assessment using the Patient-Generated Subjective Global Assessment (PG-SGA).

Impaired peripheral nerve regeneration in type-2 diabetic mouse model.

Peripheral neuropathy is one of the most common and serious complications of type-2 diabetes. Diabetic neuropathy is characterized by a distal symmetrical sensorimotor polyneuropathy, and its incidence increases in patients 40 years of age or older. In spite of extensive research over decades, there are few effective treatments for diabetic neuropathy besides glucose control and improved lifestyle.

Using Online Respondent Driven Sampling for Vietnamese Youths' Alcohol Use and Associated Risk Factors.

Objectives: The average alcohol consumption per capita among Vietnamese adults has consistently increased. Although alcohol-related disorders have been extensively studied, there is a paucity of research shedding light on this issue among Internet users. The study aimed to examine the severity of alcohol-related disorders and other associated factors that might predispose individuals towards alcohol usage in a sample of youths recruited online.

Resistance to D-tubocurarine of the rat diaphragm as compared to a limb muscle: influence of quantal transmitter release and nicotinic acetylcholine receptors.

Background: The diaphragm is resistant to competitive neuromuscular blocking agents, as compared to peripheral muscles. The basis of this difference may be a higher concentration of acetylcholine released or higher number of postsynaptic nicotinic acetylcholine receptors in diaphragmatic neuromuscular junctions.

Methods: Nerve-evoked twitch-tension was measured in rat hemidiaphragm as was Extensor digitorum longus (EDL) nerve-muscle preparation to determine the effective D-tubocurarine concentration that decreased twitch responses by 50%.

Cholinesterases and the resistance of the mouse diaphragm to the effect of tubocurarine.

Background: The diaphragm is resistant to competitive neuromuscular blocking agents. Because of the competitive mechanism of action of tubocurarine, the rate of hydrolysis of acetylcholine at the neuromuscular junction may modulate its neuromuscular blocking effect. The authors compared the neuromuscular blocking effect of tubocurarine on isolated diaphragm and extensor digitorum longus (EDL) muscles and quantified the acetylcholinesterase activity in hetero-oligomers.
