pic observation should be tried for COVID-19 pneumonia before the onset of ARDS. It will be also useful for preventing secondary lung fibrosis.
 The simulation study has revealed that selective wedge instillation under bronchoscopic observation should be tried for COVID-19 pneumonia before the onset of ARDS. It will be also useful for preventing secondary lung fibrosis.
  Acute kidney injury is common in the surgical intensive care unit (ICU).  https://www.selleckchem.com/products/liraglutide.html  It is associated with poor patient outcomes and high healthcare resource usage. This study's primary objective is to help identify which ICU patients are at high risk for acute kidney injury. Its secondary objective is to examine the effect of acute kidney injury on a patient's prognosis during and after the ICU admission.
 
  A retrospective cohort of patients admitted to a Singaporean surgical ICU between 2015 to 2017 was collated. Patients undergoing chronic dialysis were excluded. The outcomes were occurrence of ICU acute kidney injury, hospital mortality and one-year mortality. Predictors were identified using decision tree algorithms. Confirmatory analysis was performed using a generalized structural equation model.
 
  A total of 201/940 (21.4%) patients suffered acute kidney injury in the ICU. Low ICU haemoglobin levels, low ICU bicarbonate levels, ICU sepsis, low pre-ICU estimated glomerular filtration rate (eGFR) and congestive heart failure was associated with the occurrence of ICU acute kidney injury. Acute kidney injury, together with old age (> 70 years), and low pre-ICU eGFR, was associated with hospital mortality, and one-year mortality. ICU haemoglobin level was discretized into 3 risk categories for acute kidney injury high risk (haemoglobin ≤9.7 g/dL), moderate risk (haemoglobin between 9.8-12 g/dL), and low risk (haemoglobin > 12 g/dL).
 
  The occurrence of acute kidney injury is common in the surgical ICU. It is associated with a higher risk for hospital and one-year mortality. These results, in particular the identified haemoglobin thresholds, are relevant for stratifying a patient's acute kidney injury risk.

  To establish the normal reference range of fetal thorax by two-dimensional (2D) and three-dimensional (3D) ultrasound VOCAL technique and evaluate the application in diagnosing fetal thoracic malformations.
 
  A prospective cross-sectional study was undertaken involving 1077 women who have a normal singleton pregnancy at 13-40weeks gestational age (GA). 2D ultrasound and 3D ultrasound VOCAL technique were utilized to assess fetal thoracic transverse diameter, thoracic anteroposterior diameter, thoracic circumference, thoracic area, lung volume, thoracic volume and lung-to-thoracic volume ratio. The nomograms of 2D and 3D fetal thoracic measurements were created to GA. 50 cases were randomly selected to calculate intra- and inter-observer reliability and agreement. In addition, the case groups including congenital skeletal dysplasia (SD) (15), congenital diaphragmatic hernia (CDH) (30), pulmonary sequestration (PS) (25) and congenital cystic adenomatoid malformation (CCAM) (36) were assessed by the nomograms and followed up subsequently.
 
  Both 2D and 3D fetal thoracic parameters increased with GA using a quadratic regression equation. The intra- and inter-observer reliability and agreement of each thoracic parameter were excellent. 2D fetal thoracic parameters could initially evaluate the fetal thoracic development and diagnose the skeletal thoracic deformity, and lung volume, thoracic volume and lung-to-thorax volume ratio werepractical to diagnose and differentiate CDH, PS and CCAM.
 
  We have established the normal fetal thoracic reference range at 13-40weeks, which has a high value in diagnosing congenital thoracic malformations.

  Various factors, including menopausal status, educational and social background, culture, and physical and emotional health, may influence women's perceptions of menopause. This study documents the elements influencing attitudes towards menopause among women in Sarawak, Malaysia.
 
  A face-to-face interview using a validated questionnaire was conducted with 324 Sarawakian women aged 40-65 to determine the mean age of menopause and perceptions and experiences of menopause among these women.
 
  The mean age ± standard deviation of the women was 51.37 ± 5.91years. Ninety (27.8%) participants were premenopausal, 124 (38.5%) perimenopausal and 110 (33.7%) postmenopausal. The majority of these women (228; 70.4%) were local indigenous inhabitants of Sarawak. The findings show that 22.5% of the participants agreed that problems during menopause are a natural process. While 21.9% of the participants suggested that menopause should be treated medically, 32.3% argued that natural approaches for menopause symptoms are beremenopausal women comparatively expressed more positive opinions regarding menopause. Lastly, most of the women noted that menopausal symptoms are unpleasant, but that the absence of menses after menopause is a relief.
 The women's perceptions of menopause in this study were found to correspond to those in other studies on Asian women. Women with higher levels of education and premenopausal women comparatively expressed more positive opinions regarding menopause. Lastly, most of the women noted that menopausal symptoms are unpleasant, but that the absence of menses after menopause is a relief.
  Examining the predictors of summative assessment performance is important for improving educational programs and structuring appropriate learning environments for trainees. However, predictors of certification examination performance in pediatric postgraduate education have not been comprehensively investigated in Japan.
 
  The Pediatric Board Examination database in Japan, which includes 1578 postgraduate trainees from 2015 to 2016, was analyzed. The examinations included multiple-choice questions (MCQs), case summary reports, and an interview, and the predictors for each of these components were investigated by multiple regression analysis.
 
  The number of examination attempts and the training duration were significant negative predictors of the scores for the MCQ, case summary, and interview. Employment at a community hospital or private university hospital were negative predictors of the MCQ and case summary score, respectively. Female sex and the number of academic presentations positively predicted the case summary and interview scores.
