Oxygen therapy prescribing

BACKGROUND: Ferroptosis plays a crucial role in the occurrence and development of cerebral ischemia-reperfusion (I/R) injury and is regulated by mitogen-activated protein kinase 1/2 (ERK1/2). In China, Naodesheng Pills (NDSP) are prescribed to prevent and treat cerebrosclerosis and stroke. However, the protective effects and mechanism of action of NDSP against cerebral I/R-induced ferroptosis remain unclear. We investigated whether NDSP exerts its protective effects against I/R injury by regulating ferroptosis and aimed to elucidate the underlying mechanisms...

Rheumatoid arthritis (RA) is known to be caused by autoimmune disorders and can be partially alleviated through Disease-Modifying Antirheumatic Drugs (DMARDs) therapy. However, due to significant variations in the physical environment and condition of each RA patient, the types and doses of DMARDs prescribed can differ greatly. Consequently, there is a need for a platform based on patient-derived cells to determine the effectiveness of specific DMARDs for individual patient. In this study, we established an RA three-dimensional (3D) spheroid that mimics the human body's 3D environment, enabling high-throughput assays by culturing patient-derived synovial cells on a macroscale-patterned polycaprolactone (PCL) scaffold...

BACKGROUND: Intravenous administration of azithromycin has been linked to severe hypotension in some case reports in the past. We report a further case of profound shock requiring excessive use of vasopressors and extracorporeal membrane oxygenation (ECMO). CASE SUMMARY: An 18-year-old Caucasian male was admitted due to fulminant myocarditis and signs of cardiogenic shock. He had to be put on venoarterial ECMO only hours after admission. Due to the occurrence of disseminated intravascular coagulation and heparin-induced thrombocytopenia, haemodynamic support was discontinued on Day 8...

ETHNOPHARMACOLOGICAL RELEVANCE: Acute ischemic stroke (AIS) is a prominent cause of disability and mortality around the world. Achyranthes bidentata Blume, a regularly prescribed traditional Chinese herb, plays a significant role in traditional Chinese stroke therapy due to its ability to promote blood circulation and remove stasis. Ecdysterone (EDS) is one of the key active components in Achyranthes bidentata Blume, which exhibits antioxidant and anti-cerebral hypoxia properties. However, whether EDS improves AIS and the mechanism of action of AIS is still unclear...

Home oxygen therapy (HOT) is prescribed to patients with pulmonary dysfunction to improve survival and quality of life. However, ignition of oxygen can lead to burns with significant morbidity and mortality. Providers who routinely treat this patient population face an ethical issue: balancing the obligation to provide beneficial treatment to a patient with the responsibility to protect that patient from suffering avoidable burn injuries. A thorough review was conducted to assess the literature regarding ethical considerations involved in managing patients who have been burned while smoking on HOT and who continue to smoke...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is a life-saving modality but has the potential to alter the pharmacokinetics (PK) of antimicrobials. Imipenem/cilastatin/relebactam is an antibiotic with utility in treating certain multi-drug resistant Gram-negative infections. Herein, we describe the population pharmacokinetics of imipenem and relebactam in critically ill patients supported on ECMO. METHODS: Patients with infection supported on ECMO received 4-6 doses of imipenem/cilastatin/relebactam per current prescribing information based on estimated creatinine clearance...

BACKGROUND: Generic measures of health-related quality of life (HRQoL), such as the 36-Item Short Form Survey (SF-36), are widely used in assessing chronic conditions. These tools have an advantage over disease-specific instruments, as they allow comparisons across different health conditions and with the general population. In alpha-1 antitrypsin deficiency (AATD)-associated chronic obstructive pulmonary disease (COPD), HRQoL research remains scarce. This cross-sectional study evaluates the factors associated with HRQoL in a cohort of patients with AATD-associated COPD...

BACKGROUND: Co-infection with other microorganisms such as parasites in patients with COVID-19 can affect the clinical outcome and require prompt diagnosis and appropriate therapy. CASE PRESENTATION: We present a case of an adult male with chest pain, dyspnea, cough, diplopia, and anorexia who was confirmed to have acute COVID-19 pneumonia. 2 weeks prior to admission, a hydatid lung cyst was identified on examination, but the patient refused surgery. Thoracoabdominal computed tomography (CT) revealed a rupture of the lung hydatid cyst and co-infection with COVID-19...

ETHNOPHARMACOLOGICAL RELEVANCE: Ligusticum chuanxiong Hort (LCH), with the accepted name of Ligusticum striatum DC in "The Plant List" database, is a widely used ethnomedicine in treating ischemic stroke, and borneol (BO) is usually prescribed with LCH for better therapy. Our previous study confirmed their synergistic effect on neurogenesis against cerebral ischemia. However, the underlying mechanism is still unclear. AIM OF THE STUDY: More and more evidence indicated that astrocytes (ACs) might be involved in the modulation of neurogenesis via polarization reaction...

Background: When treating acute respiratory failure, both hypoxemia and hyperoxemia should be avoided. SpO2 should be monitored closely and O2 flows adjusted accordingly. Achieving this goal might be easier with automated O2 titration compared to manual titration of fixed-flow O2 We evaluated the feasibility of using an automated O2 titration device in subjects treated for acute hypoxemic respiratory failure in a tertiary care hospital. Methods: Healthcare workers received education and training about oxygen therapy and were familiarized with an automated O2 titration device (FreeO2, Oxynov, Quebec City, Canada)...

The patient was a 22-year-old woman with no comorbidities who was transferred to our hospital due to cardiac arrest. Treatment enabled return to spontaneous circulation in the patient before arriving at the hospital. At the hospital, the patient's vital signs were unstable. Vasopressors and hyperhydration therapy were administered. Computed Tomography (CT) showed no remarkable change that caused the cardiac arrest. Antibiotics were prescribed after a blood culture exam. The patient was admitted to the ICU. In the ICU, the high-capacity vasopressors, hyperhydration therapy and transfusion of fresh frozen plasma were continued...

INTRODUCTION: Portable oxygen concentrators (POCs) are medical devices that provide supplemental oxygen to patients requiring long-term oxygen therapy. However, little information is available on day-to-day patterns of how or even whether patients actively switch between their POC mobility features and flow setting options. METHODS: A retrospective analysis was conducted to assess POC usage among patients who used an Inogen One G5 POC in the USA. This study aimed (1) to describe the patterns of use of POCs, (2) to analyze their compatibility with the prescribed oxygen therapy settings, and (3) to demonstrate the contribution of POC usage to get a standardized long-term oxygen therapy (LTOT)...

BACKGROUND: Hypertension, type 2 diabetes, and cardiovascular disease affect the activities of daily living at varying degree. While the effects of aerobic exercise on functional capacity are well-documented, the extent of change for different types of exercise in these chronic conditions remains unexplored. Additionally, there is conflicting evidence regarding the role of exercise in reducing body weight. METHODS: We conducted systematic review with meta-analysis and trial sequential analysis and searched various databases from inception to July 2020...

BACKGROUND:  Sickle cell disorder (SCD) is a hereditary blood disease characterized by an abnormality in the oxygen-carrying protein hemoglobin present in red blood cells. Genetic abnormality causes these cells to become sickle-shaped, with shorter lifespan. Vaso-occlusive crisis is a major symptom of SCD: it is a sudden and severe episode of pain, and occurs when sickle-shaped cells block blood flow. This blockage can lead to tissue damage, inflammation and pain. OBJECTIVES:  This case series aims to observe the clinical outcomes from prescribing individualized homeopathic medicines along with organopathic supportive medicine in the management of SCD through the analysis of case studies of six patients from a particularly vulnerable tribal group (PVTG) in India that manifests genetic predisposition for the disease...

Drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome is an acute, rare and potentially fatal drug reaction. To date, limited studies have reported secondary Pneumocystis jirovecii pneumonia (PJP) infection during the treatment of DRESS syndrome. A 53-year-old man was admitted to the hospital due to a persistent fever lasting for 5 days. He had a medical history of hypertension, psoriasis, urticaria, and had recently been treated with carbamazepine for nerve spasm two weeks ago. After admission, the patient presented with a high fever accompanied by chills, abdominal pain, bilateral upper limb muscle pain, and generalized lymph nodes enlargement...

BACKGROUND: Continuous haemoglobin, venous blood oxygen saturation, and haematocrit (Hct) monitoring is currently not applied during continuous renal replacement therapy (CRRT). Such Hct monitoring enables estimation of changes in blood volume as percentage change (ΔBV%) from therapy start time and is incorporated into intermittent haemodialysis machines but not CRRT machines despite its potential to optimise fluid management in CRRT patients. METHODS: To overcome this problem, we used a standalone monitor (CRIT-LINE®IV, Fresenius Medical Care, Concord, USA) with an associated in-line blood chamber (CRIT-LINE®IV Blood Chamber, Fresenius Medical Care, Concord, USA) and designed our own adaptor connection piece (TekMed and Morriset, Melbourne and Brisbane, Australia) to allow these readings at the vascular access outflow and recorded data for estimated Hct and derived ΔBV% during CRRT...

Aluminum (Al) is a known neurotoxic trace element linked to Alzheimer's disease (AD). Naltrexone, an opioid antagonist, has shown promising effects in reducing neuroinflammation at lower doses than those prescribed for addiction. This study aimed to determine the neuroprotective effects of naltrexone on Al-induced neurotoxicity in an in vitro AD model. The SH-SY5Y cells were first cultivated in a standard growth medium. Subsequently, the cells were induced to differentiate by decreasing the concentration of fetal bovine serum and introducing retinoic acid (RA) into the culture media...

INTRODUCTION: Despite the efficacy of the COVID-19, the search for improvements in the management of severe/critical cases continues to be important. The aim is to demonstrate the kinetics of 4 serological markers in patients with COVID-19 who evolved in hypoxemia. METHODS: From June to December 2020, the Health Secretariat of Rondônia State, Brazil, established a home medical care service team (HMCS) that provided clinical follow-up for health professionals and military personnel with COVID-19...

Background: In the first months of the pandemic, prior to the introduction of proven-effective treatments, 15 to 37% of patients hospitalized with COVID-19 were discharged on home oxygen. After proven-effective treatments for acute COVID-19 were established by evidence-based guidelines, little is known about home oxygen requirements following hospitalization for COVID-19. Methods: This was a retrospective, multicenter cohort study of patients hospitalized for COVID-19 between October 2020 and September 2021 at three academic health centers...

INTRODUCTION: Surgical site infections still remain a major public health challenge and have become an increasing universal risk, especially for the implantation of orthopaedic devices.Unfortunately, the discovery and increasingly widespread use (especially the misuse) of antibiotics have led to the rapid appearance of antibiotic-resistant strains today; more and more infections are caused by microorganisms that fail to respond to conventional treatments.Oxygen-ozone therapy has been extensively used and studied for decades across various potential medical applications and has provided consistent effects with minimal side effects...
