Provider confidence in counseling preconception, pregnant, and postpartum patients regarding COVID-19 vaccination: A cross-sectional survey study.

Background And Aims: Healthcare provider counseling surrounding COVID-19 vaccine in pregnancy and lactation is essential to vaccination uptake in this population; however, provider knowledge and confidence are not well characterized. We aimed to assess knowledge and confidence in COVID-19 vaccine counseling among practitioners who provide care to pregnant persons and to describe factors associated with confidence in counseling.

Methods: A web-based anonymous survey was distributed via email to a cross-sectional convenience sample of Obstetrics and Gynecology, Primary Care, and Internal Medicine faculty at three hospitals in a single healthcare network in Massachusetts, United States.

Biological Effects of Intravenous Vitamin C on Neutrophil Extracellular Traps and the Endothelial Glycocalyx in Patients with Sepsis-Induced ARDS.

(1) Background: The disease-modifying mechanisms of high-dose intravenous vitamin C (HDIVC) in sepsis induced acute respiratory distress syndrome (ARDS) is unclear. (2) Methods: We performed a post hoc study of plasma biomarkers from subjects enrolled in the randomized placebo-controlled trial CITRIS-ALI. We explored the effects of HDIVC on cell-free DNA (cfDNA) and syndecan-1, surrogates for neutrophil extracellular trap (NET) formation and degradation of the endothelial glycocalyx, respectively.

Endotracheal Tube Size Is Associated With Mortality in Patients With Status Asthmaticus.

Background: There is limited evidence on the clinical importance of the endotracheal tube (ETT) size selection in patients with status asthmaticus who require invasive mechanical ventilation. We set out to explore the clinical outcomes of different ETT internal diameter sizes in subjects mechanically ventilated with status asthmaticus.

Methods: This was a retrospective study of intubated and non-intubated adults admitted for status asthmaticus between 2014-2021.

Sepsis-Induced Cardiomyopathy: a Comprehensive Review.

Purpose Of Review: To briefly review epidemiology and pathophysiology of SICM and provide a more extensive review of the data on diagnostic and management strategies.

Recent Findings: SICM is likely underdiagnosed and that has mortality implications. Current evidence supports speckle tracking echocardiography to identify decreased contractility irrespective of left ventricular ejection fraction for the diagnosis of SICM.

The Emerging Role of Vitamin C as a Treatment for Sepsis.

Sepsis, a life-threatening organ dysfunction due to a dysregulated host response to infection, is a leading cause of morbidity and mortality worldwide. Decades of research have failed to identify any specific therapeutic targets outside of antibiotics, infectious source elimination, and supportive care. More recently, vitamin C has emerged as a potential therapeutic agent to treat sepsis.

Assessing probabilistic predictions of ENSO phase and intensity from the North American Multimodel Ensemble.

Here we examine the skill of three, five, and seven-category monthly ENSO probability forecasts (1982-2015) from single and multi-model ensemble integrations of the North American Multimodel Ensemble (NMME) project. Three-category forecasts are typical and provide probabilities for the ENSO phase (El Niño, La Niña or neutral). Additional forecast categories indicate the likelihood of ENSO conditions being weak, moderate or strong.

Deterministic skill of ENSO predictions from the North American Multimodel Ensemble.

Hindcasts and real-time predictions of the east-central tropical Pacific sea surface temperature (SST) from the North American Multimodel Ensemble (NMME) system are verified for 1982-2015. Skill is examined using two deterministic verification measures: mean squared error skill score (MSESS) and anomaly correlation. Verification of eight individual models shows somewhat differing skills among them, with some models consistently producing more successful predictions than others.

Predictable Components of ENSO Evolution in Real-time Multi-Model Predictions.

The most predictable components of the El Niño-Southern Oscillation (ENSO) evolution in real-time multi-model predictions are identified by applying an empirical orthogonal function analysis of the model data that maximizes the signal-to-noise ratio (MSN EOF). The normalized Niño3.4 index is analyzed for nine 3-month overlapping seasons.

Creation and Validation of Sintered PTFE BRDF Targets & Standards.

Sintered polytetrafluoroethylene (PTFE) is an extremely stable, near-perfect Lambertian reflecting diffuser and calibration standard material that has been used by national labs, space, aerospace and commercial sectors for over two decades. New uncertainty targets of 2 % on-orbit absolute validation in the Earth Observing Systems community have challenged the industry to improve is characterization and knowledge of almost every aspect of radiometric performance (space and ground). Assuming "near perfect" reflectance for angular dependent measurements is no longer going to suffice for many program needs.

Modernizing the Estonian farmhouse, redefining the family, 1880s-1930s.

In the nineteenth century, the transition from a Baltic-German-controlled manor-and-serf economy to individually owned farmsteads transformed all aspects of life including the spatial organization and form of farmhouses in the western provinces of Tsarist Russia. Agricultural experts and social reformers discussed how to update the traditional threshing-room dwelling house (rehielamu) into a healthy dwelling for successful farmers and, after the Estonian War of Independence, for new settlers. Using material culture such as contemporary plans, I show that changing household relationships, in addition to economic and technological factors, helped to transform the ancient rehielamu into a modern dwelling.

Nitric oxide activation of a potassium channel (BK(Ca)) in feline lower esophageal sphincter.

Aim: To assess the effect of nitric oxide (NO) on the large conductance potassium channel (BK(Ca)) in isolated circular (CM) and sling (SM) muscle cells and muscle strips from the cat lower esophageal sphincter (LES) to determine its regulation of resting tone and relaxation.

Methods: Freshly enzymatically-digested and isolated circular smooth muscle cells were prepared from each LES region. To study outward K+ currents, the perforated patch clamp technique was employed.

[What is the management for foot ulcers in diabetic patients?].

The "diabetic foot" covers the spectrum of neurological, arterial and infectious foot problems that occur as a consequence of diabetes. The wounds, often due to minor injuries, may lead to amputations if not quickly treated. The treatment consists of efficiently alleviating mechanical pressure from the wound (i.

[Loan of services developing palliative care skills based on the apprentice model].

For over 25 years, the Maison Michel-Sarrazin, a private palliative care institution in the Quebec City region, has had an original agreement with other establishments in the healthcare network (hospitals, long-term residential centres and CLSCs), in the form of the loan of nursing services. Based on the findings of a study as part of a research program, this article describes the loan of nursing services and qualitatively assesses its effects on the development of nurses' palliative care skills. An evaluative descriptive approach based on two conceptual frameworks (Giddens; Patton) was used to compile the views of 79 players.

11C-methionine PET for the diagnosis and management of recurrent pituitary adenomas.

Purpose: The detection of recurrent pituitary adenoma by magnetic resonance imaging (MRI) is rendered uncertain by the tissue remodelling that follows surgery or radiotherapy. We aimed to evaluate the contribution of PET with 11C-methionine (MET-PET) in the detection and management of recurrent pituitary adenoma.

Methods: Thirty-three patients with pituitary adenoma were evaluated postoperatively by MET-PET, either because of biological evidence of active residual tumour or because of MRI demonstration of non-functional adenoma growth.

Feline lower esophageal sphincter sling and circular muscles have different functional inhibitory neuronal responses.

The lower esophageal sphincter (LES) has a circular muscle component exhibiting spontaneous tone that is relaxed by nitric oxide (NO) and a low-tone sling muscle that contracts vigorously to cholinergic stimulation but with little or no evidence of NO responsiveness. This study dissected the responses of the sling muscle to nitrergic innervation in relationship to its cholinergic innervation and circular muscle responses. Motor responses were induced by electrical field stimulation (EFS; 1-30 Hz) of muscle strips from sling and circular regions of the feline LES in the presence of cholinergic receptor inhibition (atropine) or NO synthase inhibition [NG-nitro-L-arginine (L-NNA)+/-atropine].

[Subclinical hypothyroidism].

Subclinical hypothyroidism is defined as normal serum free thyroxine and tri-iodothyronine concentrations and a slightly eleveted serum thyrotropin (TSH) concentration. Only laboratory results can detect this disorder. The causes of this disease are the same as those of overt hypothyroidism.

Two new peptides to improve post-operative gastric ileus in dog.

Peptides can influence gastrointestinal motility, and from data obtained earlier in rats, we hypothesized that MTL-RP/Ghrelin, as well as CGRP receptor antagonist 8-37, could improve gastric post-operative ileus in dog. Dogs submitted to laparotomy were perfused with or saline or CGRP 8-37 or MTL-RP/Ghrelin on days 1-4 post-operatively while gastric emptying was estimated by measuring the postprandial increase in plasma acetaminophen ingested with a meal. As expected, in saline-treated animals the gastric emptying function was impaired post-operatively.

Glucagon-like peptide-2 and common therapeutics in a murine model of ulcerative colitis.

The intestinal hormone glucagon-like peptide-2 (GLP-2) enhances bowel growth and reduces the severity of colonic injury in dextran sulfate sodium (DSS)-induced colitis in mice. In humans, ulcerative colitis is normally treated with aminosalicylates (ASAs) and corticosteroids (CSs) to reduce inflammation. However, whether the intestinotropic effects of GLP-2 are altered when combined with ASAs and/or CSs has not previously been explored.

Therapeutic potential of the intestinotropic hormone, glucagon-like peptide-2.

Glucagon-like peptide-2 (GLP-2) is a newly discovered growth factor that has been demonstrated to enhance intestinal growth and function in normal rodents and to prevent damage and facilitate intestinal repair in various animal models of intestinal insufficiency. A recent study has demonstrated that GLP-2 also acts as an intestinotropin in humans with short-bowel syndrome. The high degree of specificity of GLP-2 for induction of intestinal growth, without affecting growth of other peripheral tissues, is determined by the highly localized expression of the GLP-2 receptor in the intestinal epithelium.

Digestive motor effects and vascular actions of CGRP in dog are expressed by different receptor subtypes.

Calcitonin gene-related peptide (CGRP) is a 37 AA peptide localized in blood vessels and nerves of the GI tract. Activation of CGRP receptors (subtypes 1 or 2) usually induces vasodilation and/or muscle relaxation, but its effects in dog and on gastroduodenal motility are still unclear. This study looked for the effect of CGRP and the antagonist CGRP8-37, specific for CGRP type 1 receptor, 1) on GI motility (interdigestive and postprandial), and 2) on hemodynamy, in conscious dogs.

Characterization of lung surfactant: factors promoting formation of artifactual lipid-protein complexes.

Because uncertainty exists as to whether dipalmitoyl phosphatidylcholine, the major component of lung surfactant, is part of a lipoprotein molecule, a study was designed to investigate the relationships between the phospholipids and proteins of rabbit lung washings obtained by lavage with aqueous solutions. Surface-active sediments contained phospholipid and protein in ratios directly dependent upon the ratios in the washings from which they were obtained. Comparison of negatively stained lung washings and sediments revealed that sedimentation caused extensive aggregation of surfactant "liposomes".
