Surgery and Anesthesia in Patients with Pulmonary Hypertension.

Pulmonary hypertension is characterized by right ventricular impairment and a reduced ability to compensate for hemodynamic insults. Consequently, surgery can be challenging but is increasingly considered in view of available specific therapies and improved longer term survival. Optimal management requires a multidisciplinary patient-centered approach involving surgeons, anesthetists, pulmonary hypertension clinicians, and intensivists.

The effect of patient ethnicity on the accuracy of peripheral pulse oximetry in patients with COVID-19 pneumonitis: a single-centre, retrospective analysis.

Pulse oximetry is used widely to titrate oxygen therapy and for triage in patients who are critically ill. However, there are concerns regarding the accuracy of pulse oximetry in patients with COVID-19 pneumonitis and in patients who have a greater degree of skin pigmentation. We aimed to determine the impact of patient ethnicity on the accuracy of peripheral pulse oximetry in patients who were critically ill with COVID-19 pneumonitis by conducting a retrospective observational study comparing paired measurements of arterial oxygen saturation measured by co-oximetry on arterial blood gas analysis (SaO ) and the corresponding peripheral oxygenation saturation measured by pulse oximetry (S O ).

Critical care outcomes in patients with pre-existing pulmonary hypertension: insights from the ASPIRE registry.

Pulmonary hypertension (PH) is a life-shortening condition characterised by episodes of decompensation precipitated by factors such as disease progression, arrhythmias and sepsis. Surgery and pregnancy also place additional strain on the right ventricle. Data on critical care management in patients with pre-existing PH are scarce.

Effect of Hydrocortisone on Mortality and Organ Support in Patients With Severe COVID-19: The REMAP-CAP COVID-19 Corticosteroid Domain Randomized Clinical Trial.

Importance: Evidence regarding corticosteroid use for severe coronavirus disease 2019 (COVID-19) is limited.

Objective: To determine whether hydrocortisone improves outcome for patients with severe COVID-19.

Design, Setting, And Participants: An ongoing adaptive platform trial testing multiple interventions within multiple therapeutic domains, for example, antiviral agents, corticosteroids, or immunoglobulin.

Haemophagocytic lymphohistiocytosis in adult critical care.

Haemophagocytic lymphohistiocytosis (HLH) is a syndrome of severe immune dysregulation, characterised by extreme inflammation, fever, cytopaenias and organ dysfunction. HLH can be triggered by conditions such as infection, autoimmune disease and malignancy, among others. Both a familial and a secondary form have been described, the latter being increasingly recognised in adult patients with critical illness.

Feng shui And Emotional Response in the Critical care Environment (FARCE) study.

The aim of this study was to investigate the relationship between nursing staff emotions and their surrounding environment, using the ancient system of feng shui. Two orientations of critical care bed spaces (wind and water groups, respectively) were mapped using a western bagua. Energy or 'chi' scores for nine emotions were calculated based on the positive or negative flow of chi in each of the two groups.

The feasibility of using 'bring your own device' (BYOD) technology for electronic data capture in multicentre medical audit and research.

Large-scale audit and research projects demand robust, efficient systems for accurate data collection, handling and analysis. We utilised a multiplatform 'bring your own device' (BYOD) electronic data collection app to capture observational audit data on theatre efficiency across seven hospital Trusts in South Yorkshire in June-August 2013. None of the participating hospitals had a dedicated information governance policy for bring your own device.

'Light-chain escape-multiple myeloma'-an escape phenomenon from plateau phase: report of the largest patient series using LC-monitoring.

Purpose: More intensive and novel therapy options in multiple myeloma (MM) hold the promise to improve treatment outcome. However, disease evolution, induced with long disease duration and extensive pretreatment, has resulted in changes in the biological behaviour of MM and unusual relapse emergence, such as of extramedullary (EM) disease or a shift in secretion from intact immunoglobulin (Ig) to free-light chains (FLCs) only.

Methods: We studied ten patients since 2004, thoroughly assessed relevant patient characteristics, prominent similarities, SFLC-changes, therapy response, mode and speed of progression, and the incidence of light-chain escape (LCE)-MM within our entire myeloma patient cohort.

Monitoring of renal function in cancer patients: an ongoing challenge for clinical practice.

Background: Renal impairment (RI) has been shown to be one major risk factor in a number of diseases and is associated with a dismal clinical outcome. However, the influence of milder degrees of renal disease is less well defined, particularly not in patients with malignant diseases.

Patients And Methods: We analyzed 167 patients with solid tumors and hematological malignancies.

Sulfasalazine reduces bile acid induced apoptosis in human hepatoma cells and perfused rat livers.

Background: Bile acid induced apoptosis in hepatocytes can be antagonised by nuclear factor kappaB (NFkappaB) dependent survival pathways. Sulfasalazine modulates NFkappaB in different cell types. We aimed to determine the effects of sulfasalazine and its metabolites sulfapyridine and 5-aminosalicylic acid (5-ASA) on bile acid induced apoptosis in hepatocytes.

Phosphatidylinositol 3-kinase-dependent signaling modulates taurochenodeoxycholic acid-induced liver injury and cholestasis in perfused rat livers.

Taurochenodeoxycholic acid (TCDCA), but not glycochenodeoxycholic acid (GCDCA), activates a phosphatidylinositol 3-kinase (PI3-K)-mediated survival pathway in vitro. Here, the effects of PI3-K inhibition on TCDCA- and GCDCA-induced hepatocellular injury, apoptosis, and bile secretion were examined in the intact liver. In isolated perfused rat livers, bile flow was determined gravimetrically.
