The inorganic anions nitrate and nitrite are oxidation products of nitric oxide (NO) that have often been used as an index of NO generation. More than just being surrogate markers of NO, nitrate/nitrite can recycle to bioactive NO again. Nitrate is predominantly eliminated via the kidneys; however, there is less knowledge regarding tubular handling. The aim of this study, as part of a large randomized controlled trial, was to explore potential sex differences in renal nitrate handling during low and high dietary nitrate intake. We hypothesized that renal clearance and excretion of nitrate are higher in men compared to women.

In prehypertensive and hypertensive individuals (n=231), nitrate and nitrite were measured in plasma and urine at low dietary nitrate intake (baseline) and after 5weeks supplementation with nitrate (300mg potassium nitrate/day) or placebo (300mg potassium chloride/day). Twenty-four hours ambulatory blood pressure recordings and urine collections were conducted.

At baseline, plasma ning capacity of the kidneys, which is higher in women compared to men. This suggests higher tubular nitrate reabsorption in women but the underlying mechanism(s) warrants further investigation.

Pressure injuries are common adverse events in clinical practice, affecting the well-being of patients and causing considerable financial burden to healthcare systems. It is therefore essential to use reliable assessment tools to identify pressure injuries for early prevention. The Braden Scale is a widely used tool to assess pressure injury risk, but the literature is currently lacking in determining its accuracy. This study aimed to evaluate the accuracy of the Braden Scale in assessing pressure injury risk.

Systematic review and meta-analysis.

Articles published between 1973-2020 from periodicals indexed in the PubMed, EMBASE, CINAHL, Web of Science and the Cochrane Library were selected. Simufilam mouse Two reviewers independently selected the relevant studies for inclusion. Data were analysed by the STATA 15.0 and the RevMan 5.3 software.

In total, 60 studies involving 49,326 individuals were eligible for this meta-analysis. The pooled SEN, SPE, PLR, NLR, DOR and AUC were 0.78 (95% CI 0.74 to 0.82), 0.72 (95% CIidity. It was more suitable for mean age less then 60 years, hospitalized patients and the Caucasian population, and the cut-off value of 18 might be used for the risk assessment of pressure injuries in clinical practice. However, due to the different cut-off values used among included studies, the results had a significant heterogeneity. Future studies should explore the optimal cut-off value in the same clinical environment.Adult patients with uncorrected congenital heart diseases and chronic intracardiac shunt may develop Eisenmenger syndrome (ES) due to progressive increase of pulmonary vascular resistance, with significant morbidity and mortality. Acute decompensation of ES in conditions promoting a further increase of pulmonary vascular resistance, such as pulmonary embolism or pneumonia, can precipitate major arterial hypoxia and death. In such conditions, increasing systemic oxygenation with veno-venous extracorporeal membrane oxygenation (VV-ECMO) could be life-saving, serving as a bridge to treat a potential reversible cause for the decompensation, or to urgent lung transplantation. Anticipating the effects of VV-ECMO in this setting could ease the clinical decision to initiate such therapeutic strategy. Here, we present a series of equations to accurately predict the effects of VV-ECMO on arterial oxygenation in ES and illustrate this point by a case of ES decompensation with refractory hypoxaemia consecutive to an acute respiratory failure due to viral pneumonia.

The use of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is currently recommended for staging non-small cell lung cancer (NSCLC) in centrally located tumors, tumors >3cm, or with radiologic evidence of lymph node (LN) metastasis. Current guidelines do not recommend staging EBUS-TBNA in patients with stage I NSCLC who do not have any of the aforementioned conditions.

We hypothesize that using EBUS-TBNA is useful for detecting occult metastasis in radiologic stage I NSCLC.

In this single-center, retrospective study, charts of patients ≥18years old who underwent staging EBUS-TBNA from January 2005 to May 2019 were reviewed. Only patients with combined positron-emission tomography and computed tomography (PET/CT) scans consistent with radiologic stage I NSCLC were included. Identified variables included age, gender, personal history of any cancer, smoking history, tumor location, tumor centrality, tumor size, tumor PET activity, histopathologic type of NSCLC, and LN biopsy 23 to detect one case of occult N2 metastasis. Subgroup analysis comparing LN-positive patients based on their N stage did not show statistically significant association with any of the variables.

Based on our results and along with the existing evidence, EBUS-TBNA should be recommended as part of the routine staging in all patients with radiologic stage I NSCLC.

It recorded for the first time the words of Aboriginal women within the inpatient unit, including their perceptions of factors which may promote or impede a culturally safe environment. Eleven Aboriginal women inpatients gave interviews before discharge from the inpatient unit. Five Aboriginal Reference Group (ARG) members with experience of the inpatient unit also gave interviews, adding 'insider-outsider' perspectives. Interviews were recorded, transcribed, entered into NVivo software, and analysed inductively to raise codes and develop themes. Five interconnecting themes emerged Social Context life experience preceding, shaping, and following admission; Connection with kin, community, and culture. Control self-determination, legally and physically curtailed; Caring actions promoting reconnection and self-determination; Communication conveying caring and supporting agency, reconnection, and return to community. Findings reflected inpatient issues reported in previous studies, adding insights into the cultural concerns of Aboriginal women and offering practical clinical implications for culturally secure service delivery in an inpatient setting. Existing literature offered a basis for developing the model offered here for transcultural interaction for recovery in an inpatient setting. Attention to these findings can enhance Aboriginal women's inpatient experience and promote further research. The article complies with the COREQ-32 checklist for describing qualitative studies.

In-depth insight into haemodynamic changes during normotensive pregnancy may help identify women at risk for gestational hypertensive complications.

To determine the magnitude of changes in cardiac output and its determinants stroke volume and heart rate, and total peripheral vascular resistance during singleton normotensive and hypertensive pregnancies.

PubMed (NCBI) and Embase (Ovid) databases were searched from their inception up to November 2019.

Studies reporting original measurements of haemodynamic parameters during pregnancy together with a non-pregnant reference measurement. Studies including women using antihypertensive medication were excluded.

Pooled mean differences between pregnant and non-pregnant women, and absolute values of haemodynamic parameters were calculated for predefined gestational intervals using a random-effects model in normotensive and hypertensive pregnancy. Meta-regression analysis was used to analyse group differences in adjustments and absolute values during pregnantions.Psychiatric decision units have been developed in many countries internationally to address the pressure on inpatient services and dissatisfactory, long waits people in mental health crisis can experience in emergency departments. Research into these units lags behind their development, as they are implemented by healthcare providers to address these problems. This is the first-ever national survey to identify their prevalence, structure, activities, and contextual setting within health services, in order to provide a robust basis for future research. The response rate was high (94%), and six PDUs in England were identified. The results indicated that PDUs open 24/7, accept only voluntary patients, provide recliner chairs for sleeping rather than beds, and limit stays to 12-72 hours. PDUs are predominantly staffed by senior, qualified mental health nurses and healthcare assistants, with psychiatry input. Staffpatient ratios are high (12.1 during the day shift). Differences in PDU structure and activities (including referral pathway, length of stay, and staffpatient ratios) were identified, suggesting the optimal configuration for PDUs has not yet been established. Further research into the efficacy of this innovation is needed; PDUs potentially have a role in an integrated crisis care pathway which provides a variety of care options to service users.

Weight status and growth during childhood are indicative of healthy development throughout the lifespan. It is well understood that dietary patterns and overall quality of diet can prevent disease, improve health status and optimise growth and development. The current study investigates the relationship between overall diet quality and measures of childhood development including body mass index and height-for-age in 6-year-old children.

This cross-sectional study was conducted across 788 6-year-old children from Tehran, Iran, in 2018. Food quality score (FQS) was used to assess overall diet quality, in addition to a modified food-based diet quality score specific to children (modified FQS) developed by our group.

Participants in the highest tertile using the modified FQS had the highest height-for-age z-score (HAZ) (-0.509±0.028 vs -0.605±0.028; P=.048). In contrast, participants in the highest tertile assessed using the original FQS had a higher BMI for age z-score (BAZ) compared to participants in the first tertile (0.391±0.072 vs 0.266±0.072; P=.023). Children within the highest tertile, according to the original FQS, compared to those within the lowest tertile were 49% less likely to be categorised as severely underweight (OR 0.51; 95% CI 0.47-0.98).

Findings presented in this study demonstrate that FQS was significantly associated with participants characterised as severely underweight; however, FQS was not associated with other anthropometric parameters. Therefore, future well-designed cohort studies are required to address limitations of the current study.
