Restrain of MR activation interrupts LKB1/p-AMPK/PDK4/p-CREB/FOXO1 pathway induced by aldosterone, indicating that aldosterone action on decidualization is mainly dependent on MR stimulation. Aldosterone biosynthesized in endometrial gland during mid-secretory phase promotes decidualization via activating MR/LKB1/p-AMPK/PDK4/p-CREB/FOXO1 signaling pathway. This study provides the valuable information for understanding the underlying mechanism during decidualization.BACKGROUND Neonatal hypoxic-ischemic encephalopathy (HIE) is a dreaded disease and one of the leading causes of severe neurological dysfunction in neonates. The present study explored the functions of Sirtuin-1 (SIRT1) in neonatal HIE. MATERIAL AND METHODS A HIE neonatal rat model was generated to determine SIRT1 levels in brain tissues. Cell apoptosis and cell viability were analyzed by flow cytometry and MTT assay. qRT-PCR and Western blot analysis were used to assess gene mRNA and protein levels. Subsequently, the effect of SIRT1 on HIE was investigated in vitro by constructing an oxygen-glucose deprivation (OGD) cell model. RESULTS The effective construction of the HIE rat model was confirmed by the enhanced brain cell apoptosis and the increased expression of HIE-related molecular markers, including S100 calcium-binding protein B (S100B) and neuron-specific enolase (NSE). SIRT1 expression was downregulated in HIE rat brain tissues. These findings indicated that SIRT1 was downregulated in neuronal cells subjected to OGD. In addition, enhanced cell viability and reduced cell apoptosis were observed, suggesting that SIRT1 overexpression relieved OGD-induced neuronal cell injury. Transfection with SIRT1-siRNA further increased OGD-induced neuronal cell injury, evidenced by decreased cell viability and enhanced cell apoptosis. Finally, SIRT1 overexpression significantly downregulated p-p65 protein expression. CONCLUSIONS Our findings revealed that SIRT1 may be a novel and promising therapy target for HIE treatment.BACKGROUND Coronavirus disease 2019 (COVID-19) is an ongoing worldwide pandemic infection. Healthcare workers must utilize appropriate personal protective equipment (PPE) and infection control prevention techniques given the high risk of transmission and potential morbidity associated with COVID-19. We present a case report highlighting the strengths and potential applications of telemedicine technology in a patient’s evaluation during an ongoing emerging, novel infectious disease. CASE REPORT A 67-year-old male presented to the Emergency Department (ED) with complaints of fever. His presentation coincided with a recent declaration of a pandemic caused by COVID-19 and a known exposure. Telemedicine evaluation was performed using InTouch Provider® software (InTouch Health, Goleta, CA, USA). read more The treating clinician was able to interact with the patient entirely through observations via web camera. COVID-19 nasopharyngeal swab polymerase chain reaction testing was ordered and was performed by a dedicated triage nurse. The patient was deemed stable for discharge given his normal vital signs and well appearance. Approximately 72 hours after discharge from the ED, the patient was contacted with positive COVID-19 swab results. CONCLUSIONS We present the first known case report highlighting use of telemedicine to diagnosis COVID-19 in a patient present in the ED. With the appropriate systems in place, this method of evaluating the patient helped to limit clinician exposure, decrease risk of transmission to key personnel, and assisted with preserving PPE supplies. Use of telemedicine affords multiple benefits in the effective diagnosis, evaluation, and potential prevention of spread of COVID-19.

Ex situ heart perfusion (ESHP) limits ischemic periods and enables continuous monitoring of donated hearts; however, a validated assessment method to predict cardiac performance has yet to be established. We compare biventricular contractile and metabolic parameters measured during ESHP to determine the best evaluation strategy to estimate cardiac function following transplantation.

Donor pigs were assigned to undergo beating-heart donation (n = 9) or donation after circulatory death (n = 8) induced by hypoxia. Hearts were preserved for 4 hours with ESHP while invasive and noninvasive (NI) biventricular contractile, and metabolic assessments were performed. Following transplantation, hearts were evaluated at 3 hours of reperfusion. Spearman correlation was used to determine the relationship between ESHP parameters and posttransplant function.

We performed 17 transplants; 14 successfully weaned from bypass (beating-heart donation versus donation after circulatory death; P = 0.580). Left ventricular invas do not provide a reliable evaluation.

Left ventricular functional parameters, especially ventricular work and reserve, provided the best estimation of myocardial performance following transplantation. Furthermore, simple NI estimates of ventricular function proved useful in this setting. Right ventricular and metabolic measurements were limited in their ability to correlate with myocardial recovery. This emphasizes the need for an ESHP platform capable of assessing myocardial contractility and suggests that metabolic parameters alone do not provide a reliable evaluation.

The primary objective was to determine the impact of infant positioning on cardiopulmonary resuscitation performance during simulated pediatric cardiac arrest.

A single-center, prospective, randomized, unblinded manikin study.

Medical university-affiliated simulation facility.

Fifty-two first-line professional rescuers (n = 52).

Performance of cardiopulmonary resuscitation was determined using an infant manikin model in three different positions (on a table [T], on the provider’s forearm with the manikin’s head close to the provider’s elbow [P], and on the provider’s forearm with the manikin’s head close to the provider’s palm [D]). For the measurement of important cardiopulmonary resuscitation performance variables, a commercially available infant simulator was modified. In a randomized sequence, healthcare professionals performed single-rescuer cardiopulmonary resuscitation for 3 minutes in each position. Performances of chest compression (primary outcome), ventilation, and hands-off time were analyzed using a multilevel regression model.
