Novel p53 focus on genes secreted with the lean meats are involved in non-cell-autonomous rules.
The intrinsic vascular smooth muscle contraction and vasoconstriction show time-of-day variations, contributing to the blood pressure circadian rhythm, which is essential for cardiovascular health. This brief review provides an overview of our current understanding of the mechanisms underlying the time-of-day variations of vascular smooth muscle contraction. We discuss the potential contribution of the time-of-day variations of vasoconstriction to the physiological blood pressure circadian rhythm. Finally, we survey the data obtained in the type 2 diabetic db/db mouse model that demonstrate the alterations of the time-of-day variations of vasoconstriction and the nondipping blood pressure in diabetes.
Patients with EGFR-mutated (EGFRm) non-small cell lung cancer (NSCLC) are at particularly high risk of developing brain metastases (BrM). In addition to EGFR targeting tyrosine kinase inhibitors (TKI), radiosurgery (SRS) has an important role in the management of EGFRm BrM. However, data specific to the response and toxicity of EGFRm BrM to SRS are sparse. We evaluated the incidence of local failure (LF) and toxicity of EGFRm and EGFR-wild-type (EGFRwt) BrM treated with SRS.

We analyzed a prospective registry of BrM patients treated at our centre between 2008 and 2017 and identified EGFRm and EGFRwt NSCLC patients treated with SRS ± systemic therapy for BrM. Incidences of local failure (LF) and radionecrosis (RN) were determined, and Cox regression was performed for univariate and multivariate analyses (MVAs).

We analyzed data from 218 patients (615 lesions - 225 EGFRm and 390 EGFRwt). Median imaging follow-up per patient was 14.5 months (0.5-96.3). Prior to or concomitant with SRS, 62 % of EGFRm patients received TKI and 93 % received TKI post SRS. The 24-month incidence of LF was 6% and 16 % for EGFRm BrM and EGFRwt, respectively (0.43(0.19-0.95); p = 0.037). The 24-month incidence of RN was 4% and 6% for EGFRm and EGFRwt BrM, respectively (0.8(0.32-1.98) p = 0.63). On MVA, BrM size and prescription dose (PD) significantly correlated with a higher risk of LF and BrM size correlated with a higher risk of RN.

We observed excellent rates of response and toxicity following SRS in EGFRm compared to EGFRwt NSCLC, suggesting that EGFRm BrM have a favourable risk benefit ratio compared to EGFRwt NSCLC.

Predictive biomarkers for poor response to epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) is an area of ongoing research. This multicentre retrospective study sought to determine the impact of programmed death-ligand 1 (PD-L1) tumour proportional score (TPS) on outcome in EGFR TKI treated patients.

Patients with Stage IIIB/IV lung adenocarcinoma harbouring a sensitising EGFR mutation treated with first-line TKI at five metropolitan hospitals were included. PD-L1 TPS was determined using the Ventana anti-PD-L1 (SP263) assay. High PD-L1 expression was defined as TPS ≥ 50 %. Pitavastatin price Determinants of progression and survival hazards were modelled using Cox regression.

A total of 186 patients were included. Mean age was 67 years, 66 % were female and 54 % were Asian. Patients with high PD-L1 expression (n = 23; 12 %) had significantly shorter progression free survival (6.6 vs 13.0 months, hazard ratio (HR) 2.6 95 % CI 1.6-4.2, p < 0.0001) and overall survival (11.5 vs 32.9 months, HR 3.3, 95 % CI 1.9-5.7, p < 0.0001) compared to patients with PD-L1 low/negative tumours. This remained significant in multivariate analyses. High PD-L1 in post-TKI progression biopsies was not associated with poorer survival.

In this large, real-world cohort of EGFR-mutant lung adenocarcinoma patients, high PD-L1 expression was associated with early resistance to 1st generation EGFR TKIs and shorter survival, regardless of ethnicity.

This descriptive systematic review examines all observational studies in English investigating prevalence of depression and anxiety in adult transplant donors using bibliographic databases. Sixty-two papers were included (kidney, n = 25; liver, n = 25; bone marrow, n = 7; uterus, n = 2; lung, n = 1; kidney and lung concurrently, n = 2). Post-transplantation depression and anxiety prevalence rates (Depression 0-46.9%, Anxiety 0-66.7%) did not differ significantly from pre-transplantation and were largely comparable to the general population. Other psychiatric disorders observed included bipolar disorder, conversion disorder, adjustment disorder and sleep disorder. Other psychological outcomes observed included lower quality of life, lower satisfaction of life and regret after donation. Pre-donation risk factors such as poor physical/psychological health status, and post-donation risk factors such as complicated post-surgical recovery and poor physical/psychological health in recipients were identified, predisposing donors to poor psychological outcomes. Individuals with risk factors should be monitored and provided with social support, psychoeducation, psychotherapy and long-term follow up. Future studies should adopt consistent methodological approaches to improve comparability between various studies. More research investigating poor psychological outcomes in other organ donors besides kidney and liver donors, donors who have past psychiatric history, unrelated and parent donors is warranted.
To compare efficacy and safety of dacomitinib versus gefitinib as first-line therapy for EGFR mutation-positive advanced NSCLC in Asian patients enrolled in the ongoing ARCHER 1050 trial.

In this ongoing, randomized, open-label, phase 3 trial (NCT01774721), eligible patients with newly diagnosed advanced EGFR mutation-positive NSCLC were randomized (11) to receive oral dacomitinib 45 mg/day or oral gefitinib 250 mg/day. Randomization, by a central computer system, was stratified by race and EGFR mutation type (exon 19 deletion mutation/exon 21 L858R substitution mutation). The primary endpoint was PFS by blinded independent review.

Of 346 Asian patients, 170 were randomized to dacomitinib and 176 to gefitinib. The hazard ratio (HR) for PFS with dacomitinib versus gefitinib was 0.509 (95 % confidence interval [CI] 0.391-0.662; 1-sided p < 0.0001; median 16.5 months [95 % CI 12.9-18.4] vs. 9.3 months [95 % CI 9.2-11.0]). HR for OS with dacomitinib versus gefitinib was 0.759 (95 % CI 0.578-0.996; median 37.
