Direct evaluation of vascular inflammation in patients with COVID-19 would facilitate more efficient trials of new treatments and identify patients at risk of long-term complications who might respond to treatment. We aimed to develop a novel artificial intelligence (AI)-assisted image analysis platform that quantifies cytokine-driven vascular inflammation from routine CT angiograms, and sought to validate its prognostic value in COVID-19.
For this prospective outcomes validation study, we developed a radiotranscriptomic platform that uses RNA sequencing data from human internal mammary artery biopsies to develop novel radiomic signatures of vascular inflammation from CT angiography images. We then used this platform to train a radiotranscriptomic signature (C19-RS), derived from the perivascular space around the aorta and the internal mammary artery, to best describe cytokine-driven vascular inflammation. The prognostic value of C19-RS was validated externally in 435 patients (331 from study arm 3 and 10predicts in-hospital mortality and might allow targeted therapy.

The variation in the management and outcome of acute myocardial infarction (AMI) between rural and urban settings has been previously recognized, but there has previously been no nationwide data reported that is inclusive of the whole adult population.
All discharge records between 2004 and 2018 with AMI diagnosis were extracted from the National Inpatient Sample (NIS) database and stratified by hospital location. The primary outcome was in-hospital mortality, and secondary outcomes included (a) major adverse cardiovascular and cerebrovascular events (MACCE), (b) major bleeding, (c) acute ischemic stroke, the utilization of invasive management in the form of (d) coronary angiography (CA), and (e) percutaneous coronary intervention (PCI). The adjusted odds ratios (aOR) and 95 % confidence interval (95 % CI) were determined using multivariable logistic regression.
9,728,878 records with AMI were identified, of which 1,011,637 (10.4 %) discharges were from rural hospitals. Rural patients were older (median of 71 years vs. 67 years, p < 0.001) and had lower prevalence of the highest risk presentations of AMI than their urban counterparts. After multivariable adjustment, patients from rural hospitals had increased aOR of all-cause mortality (aOR 1.15 95 % CI 1.13-1.16) and MACCE (aOR 1.04 95 % CI 1.04-1.05), as well as the decreased aOR of coronary angiography (aOR 0.29, 95 % CI 0.29-0.29, p < 0.001) and PCI (aOR 0.40, 95 % CI 0.39-0.40, p < 0.001), compared to their urban counterparts.
Between 2004 and 2018, the risk of in-hospital mortality and MACCE in AMI patients was significantly higher in rural hospitals, with considerably lower utilization of invasive angiography and revascularization.

Postoperative day (POD) 1 laboratory tests are routinely ordered after bariatric operations.
Determine how often these laboratory tests are abnormal and whether they represent value-added care.
Academic medical center, United States.
Patients undergoing bariatric operations for obesity and complications from prior bariatric surgery from 1 January 2011 to 12 December 2020 at a single institution were identified. Patients with POD 1 hemoglobin, potassium, creatinine, or glucose serum laboratory tests obtained before 0800 on POD 1 were reviewed. Laboratory-specific exclusion criteria were applied. Abnormal laboratory test results were a hemoglobin < 8.0 g/dL or a hemoglobin drop of > 3.0 g/dL; a potassium < 3.5 mmol/L (hypokalemia), 5.5-5.9 mmol/L (mild hyperkalemia), or ≥ 6.0 mmol/L (severe hyperkalemia); a creatinine increase of 0.3 g/dL or 1.5X the preoperative value (acute kidney injury); and a glucose > 180 mg/dL (hyperglycemia). Intervention for abnormal hemoglobin, potassium, and glucoinuation of a surgical tradition rather than a clinically valuable tool. POD 1 laboratory tests should be ordered based on specific patient co-morbidities and clinical criteria.
Identification of tumours harbouring an overall active immune phenotype may help for selecting patients with advanced head and neck squamous cell carcinomas (HNSCC) and non-small cell lung cancer (NSCLC) who may benefit from immunotherapies. Our objective was to develop a reliable and stable scoring system to identify those immunologically active tumours.
Using gene expression profiles of 421 HNSCC, we developed a score to identify immunologically active tumours. Validation of the 'HOT' score was done in 40 HNSCC and 992 NSCLC. Stability of the 'HOT' score was tested in paired HNSCC samples from diagnostic biopsies versus surgically resected specimens, untreated versus recurrent samples, and pre-versus post-cetuximab samples in a total of 76 patients. The association between the 'HOT' score with overall survival (OS) and progression-free survival (PFS) was tested in 184 patients with HNSCC or NSCLC treated with PD-1/PD-L1 inhibitors.
A 27-gene expression based 'HOT' score was correlated with (i) PD-L1 and IDO1 expression, (ii) TCD8 infiltrate and (iii) activation of the IFN-γ pathway. The HOT score concordance when comparing diagnostic biopsies and surgically resected specimens was higher than in untreated samples versus recurrent or pre-versus post-cetuximab samples. In 102 and 82 patients with HNSCC or NSCLC treated with PD-1/PD-L1 inhibitors, the HOT score was associated with an improved OS and PFS in multivariate analysis.
The 'HOT' score is a simple and robust approach to identify real-world patients with HNSCC and NSCLC immunologically active tumours who may benefit from PD-1/PD-L1 inhibitors.

One is the international collaborative studies, such as Seven Countries Study, NI-HON-SAN Study, International Study of Salt and Blood Pressure (INTERSALT), International Study of Macro-and Micro-nutrients and Blood Pressure (INTERMAP), and Monitoring of Cardiovascular Disease (MONICA). The next one is the several cohort studies in Japanese unique surveys, such as Hisayama Study, Osaka-Akita Study, Tanno-Sobetsu Study, Suita Study, Ohazama Study, National Integrated Project for Prospective Observation of Noncommunicable Disease and Its Trends in the Aged (NIPPON DATA), Japan Collaborative Cohort (JACC), and Japan Public Health Center-Based Study (JPHC). Antiviral inhibitor Finally, some recent special meta-analysis in Japan are Japan Arteriosclerosis Longitudinal Study (JALS) and Evidence for Cardio-vascular Prevention from Observational Cohorts in Japan (EPOCH-JAPAN). The aim of this review is to introduce the history of epidemiologcal study, especially, cardiovascular epidemiology from the mid-20th century to in the early 21st century by dividing three patterns.
To evaluate the accuracy and validity of images with smartphone compared to the RetCam® system for the diagnosis of retinopathy of prematurity (ROP).
Observational, longitudinal and masked study carried out at the Dr. Elías Santana hospital. Infants with birth weight ≤1500g, gestational age ≤30 weeks and/or patients exposed to risk factors or complications linked to ROP were included. These subjects were screened using images with smartphone or RetCam®, both compared to conventional fundoscopy. The ICROP classification was used for staging. The main results analyzed were sensitivity, specificity, positive predictive values and kappa index.
915 images (n=121) were obtained, distributed in smartphone group (50.4%) and RetCam® group (49.6%) between August 2020 and March 2021. Subjects with ROP had lower gestational age (30.2sem±2.8), birth weight (1361g±398), and greater exposure to oxygen therapy (12.8 days±11.3). The RetCam® group presented sensitivity=80%, specificity=78%, positive predictive value = 90% and kappa index=0.70. The smartphone group presented sensitivity = 88%, specificity = 90%, positive predictive value=93.75% and kappa index=0.81.
Both diagnostic methods were accurate to identify ROP. The smartphone group obtained superior results with excellent resolution, representing a cost-effective method to create a global impact on reducing preventable blindness in the pediatric population.

Can 1-day old human unfertilized oocytes activate and blastulate after exposure to calcium ionophore (Ca.I) A23187?
Prospective randomized trial analysis of sibling oocytes. Seventy unfertilized sibling oocytes from 24 couples were randomly split into two groups. In the treatment group, 35 oocytes were cultured with 5-µM Ca.I A23187 for 10 min, washed and cultured until day 6 of development (D+6). The remaining 35 oocytes (control group) were similarly cultured until D+6. Activation, cleavage and blastulation rates were compared between the two groups.
Comparable activation rates were observed in the oocytes incubated with Ca.I A23187 and in the control group (11.4% versus 17.1%; P = 0.49). The cleavage rate observed was 45.7% in both groups. None of the embryos reached blastocyst stage.
Activation and cleavage can occur in unfertilized oocytes after the diagnosis of failure to fertilize. Unfortunately, the prevalence of activation is not affected by exposure to Ca.I A23187. Additionally, these embryos have no tangible reproductive potential as they arrest before reaching the blastocyst stage.

The effects of radiotherapy (RT) patients' health-related quality of life (HRQoL) are usually compared to those of other treatment modalities instead of HRQoL of the general population in oncological studies. We examined HRQoL of patients with an early prostate cancer (PC) not receiving hormonal treatment up to 3 years after RT using the 15D instrument and the FACT-P questionnaire.
The 15D results were compared to those in the age-standardized general male population (N=952) using an independent-sample t test. The study population (N=73) received RT either with 78/2 Gy, 60/3 Gy or 36.25/7.25 Gy fractionation.
No significant differences in the mean total HRQoL scores were found between the RT groups and the general male population at any time point. Patients with PC had more depression (P=.015) and distress (P=.029) than the general male population before the treatment and depression up to 3 months after treatment (P=.019), which did not persist at 3 years. The sexual activity dimension had declined by the end of treatment, and this decline persisted 3 years later (P=.
