Venovenous extracorporeal membrane oxygenation has been recommended as an effective rescue therapy for select critically ill patients with COVID-19. This case report describes a first experience caring for a patient with COVID-19 who received venovenous extracorporeal membrane oxygenation and expands the literature by discussing relevant nursing management and operational considerations.

A 46-year-old man presented to a hospital emergency department with pleuritic chest pain, dyspnea, anorexia, and chills. The patient was intubated for pneumonia-associated acute respiratory distress syndrome.

A nasopharyngeal swab specimen was positive for SARS-CoV-2, and chest radiography confirmed a diagnosis of COVID-19 with acute respiratory distress syndrome.

After no improvement with mechanical ventilation and prone positioning, the patient began receiving venovenous extracorporeal membrane oxygenation and was transferred to an extracorporeal membrane oxygenation center. Frontline critical care nurses played a vatients during this pandemic.

Prevention of iron deficiency in African children is a public health priority. Current WHO/FAO estimations of iron requirements are derived from factorial estimates based on healthy, iron-sufficient "model" children using data derived mainly from adults.

In this study, we aimed to quantify iron absorption, loss, and balance in apparently healthy 5- to 7-y-old children living in rural Africa.

We directly measured long-term iron absorption and iron loss in a 2-y observational study in Malawian children (n=48) using a novel stable iron isotope method.

Of the 36 children with height-for-age and weight-for-age z scores ≥-2, 13 (36%) were iron deficient (soluble transferrin receptor >8.3 mg/L) and 23 were iron sufficient. Iron-deficient children weighed more than iron-sufficient children [mean difference (95% CI) +2.1 (1.4, 2.7) kg; P=0.01]. Mean iron losses did not differ significantly between iron-deficient and iron-sufficient children and were comparable to WHO/FAO median estimates of 19 µg/(d×kg). In iron-sufficient children, median (95% CI) dietary iron absorption was 32 (28, 34) µg/(d×kg), comparable to WHO/FAO-estimated median requirements of 32 µg/(d×kg). In iron-deficient children, absorption of 28 (25, 30) µg/(d×kg) was not increased to correct their iron deficit, likely because of a lack of bioavailable dietary iron. Twelve children (25%) were undernourished (underweight, stunted, or both).

Our results suggest that WHO/FAO iron requirements are adequate for healthy iron-sufficient children in this rural area of Malawi, but iron-deficient children require additional bioavailable iron to correct their iron deficit.

Bariatric surgery is considered the most effective treatment for severe obesity. Despite this wide success, bariatric surgery is associated with increased risks of nutritional deficiencies.

To examine whether Roux-en-Y-gastric bypass (RYGB) alters essential fatty acid (FA) status and inflammation markers.

Subjects with obesity (n=28; BMI > 40kg/m2; mean age 48 years) were studied before and 1 year after RYGB. We collected blood samples before and 12 months after RYGB, and analyzed FA in RBCs and peripheral blood mononuclear cells (PBMC), and measured inflammation parameters in plasma. The proportion of total n-3 FAs was the primary outcome, while parameters related to other FAs and inflammation factors were the secondary parameters. Selleck Sotorasib In addition, PBMCs from 15 of the participants were cultured alone or with 100 and 200 μM DHA, and the production of IL-6, IL-1β, PGE2, and prostaglandin F2-alpha (PGF2α) was assayed after endotoxin (LPS) stimulation.

RYGB induced a significant reduction of BMI (-30%) aplementation would merit a trial in bariatric patients.Although levodopa remains the most effective drug for symptomatic management of Parkinson's Disease (PD), treatment during advanced disease stages may raise unpredictable motor fluctuations and other complications. Counteracting these complications with other pharmacological therapies may prompt a vicious circle of side effects, and here, nutritional therapy may have great potential. Knowledge about the role of diet in PD is emerging and multiple studies have investigated nutritional support specifically with respect to levodopa therapy. With this systematic review, we aim to give a comprehensive overview of dietary approaches to optimize levodopa treatment in PD. A systematic search was performed using the databases of PubMed and Scopus between January 1985 and September 2020. Nutritional interventions with the rationale to optimize levodopa therapy in human PD patients were eligible for this study and their quality was assessed with the Cochrane risk-of-bias tool. In total, we included 22 papers that addreseinemia, and importantly, their potential to treat consequent metabolic and clinical complications warrants future research.

The gut microbiota (GM)-bone axis has emerged as a crucial mediator of bone homeostasis. Estrogen deficiency-induced bone loss is closely associated with an altered GM. However, the underlying mechanisms remain unclear.

We sought to explore the putative effects of GM on estrogen deficiency-induced bone loss and determine a potential mechanism.

Fecal samples collected from postmenopausal women with osteoporosis (PMO) and with normal bone mass (PMN) were examined by 16S ribosomal RNA (rRNA) gene sequencing and analysis. Prevotella histicola, a typical species of Prevotella, was orally given to female C57BL6/J mice after ovariectomy [ovariectomized (OVX)]. The primary outcomes were changes in bone microstructures as measured by micro-computed tomography scanning and bone histomorphometry analysis. Secondary outcomes included changes in osteoclast activity, the expression of osteoclastogenic cytokines, and gut permeability, which were measured by ELISA, qRT-PCR, western blot, and immunofluorescence.

As demonstrated through 16S rRNA gene sequencing and analysis, the GM in the PMO group featured a significantly decreased proportion of the genus Prevotella in comparison with that in the PMN group (∼60%, P<0.
