The goal of the study is to determine the inter-rater agreement on multiple factors that were utilized to evaluate the quality of pediatric chest X-ray exams from different levels of healthcare provision in an African setting.

The image quality of pediatric chest X-rays from 3 South African medical centers of varying level of healthcare service were retrospectively assessed by 3 raters for 12 quality factors including (1) absent body parts; (2) under inspiration; (3) patient rotation; (4) scapula in the way; (5) patient kyphosis/lordosis; (6) artefact/foreign body; (7) central vessel visualization; (8) peripheral vessels visualization; (9) poor collimation; and (10) trachea and bronchi visualization; (11) post-cardiac vessel visualization; and (12) absent or wrong image orientation. Analysis was performed using the Brennan--Prediger coefficient of agreement for inter-rater reliability and Cochran's Q statistic and McNemar's test for inter-rater bias.

1077 X-rays were reviewed. The least difference betwethe factors used to assess the quality of a chest X-ray in children demonstrate poor reliability despite mitigation against variations in training, standard quality definitions and level of healthcare service provision. New definitions, objective measures and recording tools for assessing pediatric chest radiographic quality are required.

The purpose of this study was to determine the prevalence of throat pain and otalgia as presenting symptoms in patients with oropharyngeal squamous cell carcinoma (OPSCC) stratified by the cancer being their first or recurrent/second primary head and neck cancer (fHNC or rsHNC).

A retrospective analysis of patients operated on for OPSCC was performed. The primary predictor variable was HNC instance (fHNC/rsHNC) with outcome variables of throat pain and/or otalgia. selleck Chi-square analysis was performed to test for significant associations between HNC instance and pain variables. Unadjusted odds ratios were calculated.

Eighty-nine patients met the inclusion criteria. Patients with OPSCC as an rsHNC had 4.67 times higher odds of throat pain (95% confidence interval [CI], 1.45-15.06) than those with OPSCC as an fHNC and had 20.22 times higher odds of simultaneous throat pain and otalgia (95% CI, 4.76-85.97) than those presenting with an fHNC. Current smoking status and human papillomavirus (HPV)-negative disease were also significantly predictive of rsHNC. HPV-negative disease was also predictive of pain.

In addition to the known associations of smoking and HPV status on recurrence and pain, there is a statistically significant association between cancer instance and pain in patients presenting with newly diagnosed, operable OPSCC.

This study was designed to assess the prognostic value of pericoronary adipose tissue (PCAT) computed tomography attenuation (PCATa) beyond quantitative coronary computed tomography angiography (CCTA)-derived plaque volume and positron emission tomography determined ischemia.

Inflammation plays a crucial role in atherosclerosis. PCATa has been shown to assess coronary-specific inflammation and is of prognostic value in patients with suspected coronary artery disease (CAD).

A total of 539 patients who underwent CCTA and [

O]H

O PET perfusion imaging because of suspected CAD were included. Imaging assessment included coronary artery calcium score (CACS), presence of obstructive CAD (≥50% stenosis) and high-risk plaques (HRPs), total plaque volume (TPV), calcified/noncalcified plaque volume (CPV/NCPV), PCATa, and myocardial ischemia. The endpoint was a composite of death and nonfatal myocardial infarction. Prognostic thresholds were determined for quantitative CCTA variables.

During a median follow-up atherosclerotic burden and ischemia were more strongly associated with outcome than RCA PCATa. Nonetheless, RCA PCATa was of prognostic value beyond clinical characteristics, CACS, obstructive CAD, HRPs, TPV, CPV, NCPV, and ischemia.

Is it possible to identify monochorionic twin pregnancies before blastocyst transfer based on maternal or embryo characteristics registered by time lapse?

A retrospective cohort study including women who received fertility treatment (n = 6501) between 2010 and 2019 at two fertility clinics in central Denmark. The treatment resulted in 2239 pregnancies after single embryo transfer (SET) and, of those, 43 (1.92%) were monochorionic twins. Baseline characteristics, information on assisted reproductive technology and ultrasonic findings at gestational week 8 were collected on all women. Furthermore, a blinded time lapse annotation analysis was conducted by two independent laboratory technicians on a total of 85 embryos. A total of 22 embryos leading to monochorionic pregnancies were matched with 63 embryos leading to singleton pregnancies.

A monochorionic twin rate of 1.92% was found. No significant difference was found in maternal age, the use of intracytoplasmic sperm injection compared with IVF, indication for treatment or other maternal characteristics. In the blinded annotation analysis, inner cell mass grade A was associated with an increased risk of twinning (P = 0.04) in fresh embryos. The s3 division timing was found to be significantly shorter in fresh twin compared with singleton embryos (P = 0.006). No other time lapse parameters were found to be characteristic of twin embryos.

To the best of our knowledge, this is the first blinded annotation study to identify aspects in time lapse resulting in monochorionic twins after SET. Whether inner cell mass grade A and s3 reflect a biological background for monochorionic twinning merits further investigation.
