Objectives: To determine incidence and risk factors for hypertension in childhood nephrotic syndrome.
Study Design: Using data from the Insight into Nephrotic Syndrome (INSIGHT) study, a prospective observational childhood nephrotic syndrome cohort from Toronto, Canada, we evaluated hypertension incidence and time-to-hypertension overall and stratified by 1) steroid-resistance or steroid-sensitivity, and 2) frequently-relapsing, steroid dependent, or infrequently-relapsing. Hypertension was defined as stage 1-2 hypertensive blood pressure on two consecutive visits or anti-hypertensive medication initiation.
Background: Steroid-sparing immunosuppression is used in 50% of children with nephrotic syndrome, to prevent relapses and steroid-related toxicity. However, rates and predictors of prolonged remission after cyclophosphamide and tacrolimus are uncertain.
Methods: Retrospective analysis of children (1-18 years) enrolled in a longitudinal cohort.
Article Synopsis
- Blunt chest trauma is a significant medical condition requiring quick evaluation to decide on possible surgery, and non-contrast CT scans are more effective than standard chest X-rays for detecting injuries.
- The study at Lady Reading Hospital involved 246 patients, mostly males aged 50 and older, with road traffic accidents being the primary cause of injury; non-contrast CT revealed more cases of hemopneumothorax compared to chest X-rays.
- Findings highlight that non-contrast CT scans are a reliable diagnostic method for blunt chest trauma, influencing treatment decisions and aligning with existing research.
In this study, six individual machine learning (ML) models and a stacked ensemble model (SEM) were used for daytime visibility estimation at Bangkok airport during the dry season (November-April) for 2017-2022. The individual ML models are random forest, adaptive boosting, gradient boosting, extreme gradient boosting, light gradient boosting machine, and cat boosting. The SEM was developed by the combination of outputs from the individual models.

Materials And Methods: The recent published IQSC from 0 to 4 were used by radiologists for the assessment of image quality. The entire data were collected for five types (brain CT, chest CT, chest HRCT, abdomen KUB CT and abdomen + pelvic CT) CT investigations based on anatomic region (head, chest and abdomen + pelvic).
