Patients with advanced non-small cell lung cancer (NSCLC) benefit from treatment with immune checkpoint inhibitors (ICIs). Biomarkers such as programmed death-ligand 1 (PD-L1), the tumor mutational burden (TMB) and the mismatch repair (MMR) status are used to predict the prognosis of ICIs therapy. Nevertheless, novel biomarkers need to be further investigated, and a systematic prognostic model is needed for the evaluation of the survival risks of ICIs treatment.

A cohort of 240 patients who received ICIs from the cBioPortal for Cancer Genomics was evaluated in this research. Clinical information and targeted sequencing data were acquired for analyses. The Kaplan-Meier plot method was used to perform survival analyses, and selected variables were then confirmed by a novel nomogram constructed by the “rms” package of R software.

Seven percent of the NSCLC patients harbored ARID1A mutations, while 4% of the NSCLC patients harbored ARID1B mutations. this website Mutations in ARID1A and ARID1B were confirmed to be associated with sensitivity to ICIs. Patients harboring these mutations were found to have a better response to treatment (ARID1A P = 0.045; ARID1B P = 0.034) and prolonged progression-free survival (ARID1B P = 0.032). Here, a novel nomogram was constructed to predict the prognosis of ICIs treatment. Elevation of the TMB, enhanced expression of PD-L1 and activation of the antigen presentation process and cellular immunity were found to be correlated with ARID1A and ARID1B mutations.

ARID1A and ARID1B could serve as novel biomarkers for the prognosis and sensitivity to ICIs of advanced NSCLC.

Hope is a positive coping mechanism that is important at all stages of illness, more so for palliative care patients.

To explore the experiences of hope of palliative care patients.

A qualitative study was conducted at University of Malaya, Kuala Lumpur, Malaysia. Adult palliative care in-patients were recruited and interviewed with semi structured questions on hope. Transcripts from the interviews were thematically analyzed with qualitative data management software NVIVO.

20 palliative care patients participated in the study. The themes generated from thematic analysis were (1) The notions of hope, (2) The sources and barriers of hope and (3) The contents of hope.

Hope is an ever-present source of energy that gives people strength to carry on even in the most adverse situations. Understanding hope from the palliative care perspective may allow healthcare providers to develop strategies to better foster hope in the terminally ill.

This study aimed to investigate the effects of melatonin on cardiac oxidative stress and apoptosis in the fetal heart in RUPP rats.

The fetal heart samples were obtained from melatonin administrated RUPP rats.

Our results indicate that preeclampsia exacerbated by melatonin deficiency triggers hypoxic conditions, both mis/un-folded protein response, oxidative stress-induced DNA damage and apoptosis. Melatonin treatment provided significant therapeutic effects on fetal hearts via regulating all these stress response at cellular and molecular levels.

Melatonin may be considered as a potential molecule for development of preventive strategies to reduce the PE induced risk of cardiovascular diseases in offspring.

An inverse relationship has been described between procedural success and outcomes of all major cardiovascular procedures. However, this relationship has not been studied for percutaneous coronary intervention (PCI) of chronic total occlusion (CTO).

We analyzed the data on patients enrolled in Blue Cross Blue Shield of Michigan Cardiovascular Consortium registry in Michigan (January 1, 2010 to March 31, 2018) to evaluate the association of operator and hospital experience with procedural success and outcomes of patients undergoing CTO-PCI. CTO-PCI was defined as intervention of a 100% occluded coronary artery presumed to be ≥3 months old.

Among 210 172 patients enrolled in the registry, 7389 (3.5%) CTO-PCIs were attempted with a success rate of 53%. CTO-PCI success increased with operator experience (45% and 65% in the lowest and highest experience tertiles) and was the highest for highly experienced operators at higher experience centers and the lowest for inexperienced operators at low experience hosply related to procedural success but were not related to major adverse cardiac event among patients undergoing CTO-PCIs. Inexperienced operators at high experience centers had significantly higher success but not major adverse cardiac event rates compared with inexperienced operators at low experience centers. These data suggested that CTO-PCI safety and success could potentially be improved by selective referral of these procedures to experienced operators working at highly experienced centers.

Coronavirus disease 2019 (COVID-19) pandemic has led to a fast and radical transformation in social, economic, and healthcare networks. COVID-19 outbreak may thus have profound indirect consequences on clinical presentation and management of patients with ST-segment-elevation myocardial infarction (STEMI). Aim of this study was to assess clinical features of patients with STEMI during COVID-19 pandemic.

This single-center, prospective study from a regional public service healthcare hub in Milan included all consecutive patients with STEMI admitted to our institute from February 21 to April 1, 2020 (during COVID-19 pandemic). These patients were compared with a historical cohort of patients admitted for STEMI during the analogous time period (February 21 to April 1) in 2018 and 2019, in terms of time from symptoms onset to hospital admission, clinical characteristics, and in-hospital outcomes.

A total of 26 patients were admitted for STEMI during the study period, and 7 (26.9%) of these patients tested positive for severe acute respiratory syndrome coronavirus 2.
