Metaheuristics pertaining to several series position: A planned out evaluation.
Ingested inorganic nitrate (NO3⁻) has multiple effects in the human body including vasodilation, inhibition of platelet aggregation, and improved skeletal muscle function. The functional effects of oral NO3⁻ involve the in vivo reduction of NO3⁻ to nitrite (NO2⁻) and thence to nitric oxide (NO). However, the potential involvement of S-nitrosothiol (RSNO) formation is unclear. We hypothesised that the RSNO concentration ([RSNO]) in red blood cells (RBCs) and plasma is increased by NO3⁻-rich beetroot juice ingestion. In healthy human volunteers, we tested the effect of dietary supplementation with NO3⁻-rich beetroot juice (BR) or NO3⁻-depleted beetroot juice (placebo; PL) on [RSNO], [NO3⁻] and [NO2⁻] in RBCs, whole blood and plasma, as measured by ozone-based chemiluminescence. The median basal [RSNO] in plasma samples (n = 22) was 10 (5-13) nM (interquartile range in brackets). In comparison, the median values for basal [RSNO] in the corresponding RBC preparations (n = 19) and whole blood samples (n = 19) were higher (p less then 0.001) than in plasma, being 40 (30-60) nM and 35 (25-80) nM, respectively. BAY 2666605 clinical trial The median RBC [RSNO] in a separate cohort of healthy subjects (n = 5) was increased to 110 (93-125) nM after ingesting BR (12.8 mmol NO3⁻) compared to a corresponding baseline value of 25 (21-31) nM (Mann-Whitney test, p less then 0.01). The median plasma [RSNO] in another cohort of healthy subjects (n = 14) was increased almost ten-fold to 104 (58-151) nM after BR supplementation (7 × 6.4 mmol of NO3⁻ over two days, p less then 0.01) compared to PL. In conclusion, RBC and plasma [RSNO] are increased by BR ingestion. In addition to NO2⁻, RSNO may be involved in dietary NO3⁻ metabolism/actions.Romania is on the first place in Europe with an annual production of honey of 30.9 thousand tons in 2018, while the European Union is on the second place in the world with a total of 283 thousand tons. The most part of the honey production from Romania is exported. The aim of this study was to estimate internal radiation doses and lifetime cancer risk from honey ingestion sampled from several locations on the Romanian territory. The activity concentration of 137Cs and 238U is found to be below the detection limit of the method. The activity of 226Ra ranged from lower than the minimum detectable value ( less then 1.08 Bq·kg-1) to 7.35 ± 1.73 Bq·kg-1. For 232Th and 40K the average recorded values were 1.51 ± 0.74 and 24.08 ± 4.37 Bq·kg-1, respectively. The annual effective dose due to the intake of 232Th, 226Ra, 40K has been assessed ranging from 0.08 to 0.47 (μSv·y-1), 0.35 to 1.65 (μSv·y-1) and 0.04 to 0.33 (μSv·y-1), respectively. 26Ra gives the largest contribution (56-82%) to the total annual effective dose due to ingestion received by consumption of honey, in the samples where it was identified. In the other samples (where 226Ra was below the detection limit), the largest contribution to annual effective dose is due to 232Th (45-85%). The values obtained from the lifetime cancer risk calculation range in the domain from 2.85·10-7 to 1.78·10-6 for 232Th, 1.33·10-6 to 6.22·10-6 for 226Ra and 1.38·10-7 to 1.25·10-6 for 40K. For 137Cs, only one value was recorded 2.20·10-8. The 232Th, 226Ra, 40K and 137Cs activities measured in the present work were comparable with completion of others activated values of honey samples around Europe.
Diffuse Idiopathic Pulmonary NeuroEndocrine Cell Hyperplasia (DIPNECH) is a rare disease often associated with carcinoid tumors. We aimed at evaluating the impact of DIPNECH on characteristics and prognosis of patients who underwent radical treatment of pulmonary carcinoid tumors.

We reviewed all patients operated on for curative-intent resection of carcinoid tumor in our department from 2001 to 2020. Cases exhibiting both pathological and radiological features of DIPNECH, as assessed by respective thoracic expert physicians, were analyzed separately.

172 cases of resected carcinoid tumors were identified, including 25 (14.5 %) harboring pathological criteria of DIPNECH and radiologic features like mosaic attenuation (92.0 %), multiple nodules < 5 mm (76.0 %), and mucoid impactions (32 %). In DIPNECH patients, major pulmonary resections were usually performed (92.0 %) and resected tumors were mostly classified as pT1 (92 %). Mean Ki67 staining was 3.7 ± 5.2 %. The early postoperative period was mostlnagement.
The aim of this study was to determine overall survival and recurrence-free survival after resection of bronchopulmonary carcinoids by means of predominantly minimally invasive surgery and lung-sparing resections. In addition, we aimed to identify prognostic factors for overall survival.

Retrospective review of consecutive patients operated for bronchopulmonary carcinoids between January 2009 and October 2020 identified from a prospectively collected database.

A total of 236 patients representing 240 cases of bronchopulmonary carcinoids were included. Of these, 212 (88.3 %) were typical carcinoids, while 28 (11.7 %) were atypical carcinoids. A Video-Assisted Thoracoscopic Surgery (VATS) approach was used in 75 % of cases. There was no 30-day mortality. The median follow-up was 5.6 years for overall survival and 4.7 years for recurrence-free survival. 5- and 10-year overall survival rates were 89 % and 71 %, while 5- and 10-year recurrence-free survival rates were 84 % and 71 %. Patients with atypical carcinoids had significantly reduced overall survival and recurrence-free survival rates (HR 3.4; 95 % CI 1.5-7.6; p = 0.003 and HR 5.4; 95 % CI 2.6-11.4; p < 0.001). Independent predictors of overall survival included atypical carcinoid (HR 2.7; 95 % CI 1.2-6.0; p = 0.018) and age > 60 years (HR 2.9; 95 % CI 1.2-7.3; p = 0.021).

Surgery for bronchopulmonary carcinoids by means of predominantly VATS and lung-sparing resections provides favorable long-term survival. Atypical carcinoids and age > 60 years are independent predictors of poor overall survival.
60 years are independent predictors of poor overall survival.
