RESUMO
BACKGROUND: Pulmonary embolism (PE) diagnosis can sometimes be challenging due to the disease having nonspecific signs and symptoms at the time of presentation. The present study aimed to evaluate the validity of the D-dimer in combination with the revised Geneva score (RGS) in the prediction of pulmonary embolism. PATIENTS AND METHODS: This is a retrospective study of 2010 patients with suspected PE who had undergone both D-dimer testing followed by chest CT angiography (CTPA), irrespective of the D-dimer test results, at King Abdulaziz Medical City, Riyadh, Saudi Arabia, over 3 years, from Jan. 2016 to Jan. 2019. The predictive accuracy of D-dimer, adjusted D-dimer, and RGS was calculated. The receiver operating characteristic "ROC" curve was applied to allocate the optimum RGS cutoff for PE prediction. RESULTS: The overall prevalence of PE was 16%. It was 0%, 25.8%, and 88.9% in low, intermediate, and high clinical probability categories of RGS, respectively. Both conventional and age-adjusted D-dimer thresholds showed significant level of agreement (kappa=0.81, p<0.001), high sensitivity (94% and 92.8%), high negative predictive value "NPV" (91.2% and 91.4%), low specificity (12.3% and 15.3%), and low positive predictive value "PPV" (17.5% and 17.8%), respectively. Combination of the age-adjusted D-dimer threshold and RGS at a cut-off of 5 points would provide 100% sensitivity and 61.7% specificity 34.1% PPV, 100% NPV, and 0.87 area under the curve "AUC". At an RGS cutoff <5 points, PE could have been ruled out in more than one-half (1036, 51.5%) of all suspected cases, and would have saved the cost of CTPA. CONCLUSION: Conventional and age-adjusted D-dimer tests showed high levels of agreement in the prediction of PE, high sensitivity, and low specificity. RGS has a good performance in PE prediction. Using the revised Geneva score alone rules out PE for more than one-half of all suspected without further imaging.
RESUMO
BACKGROUND: Caring for a child with Type 1 Diabetes (T1D) pose a significant burden on parents especially when they struggle with their child's T1D management. The experience of not coping or struggling to cope increases the level of stress in parents, which may adversely affect their child's diabetic control (Al Dubayee et al, Horm Res Paediatr 88:2019). In this study, we assessed the level of stress parents experience in caring for a child diagnosed with T1D in four different domains. METHODS: This was a cross-sectional study conducted in two specialized diabetic centers in Riyadh, Saudi Arabia, from February to May 2015 (Al Dubayee et al, Horm Res Paediatr 88:2019). We used an Arabic translation of the validated Pediatric Inventory for Parents (PIP) questionnaire. The frequency and perceived difficulty of stressful events were rated by interviewing parents caring for children with T1D using two 5-point Likert scales. RESULTS: The sample realized as 390 parents. The level of stress increased in separated and unemployed parents. The frequency (mean 64.9/210, SD 7.529) and difficulty (mean 65.3/210, SD 9.448) indices of the parental level of stress were compared with variables possibly associated with stress. Both of the frequency difficulty indices correlated with the marital status, the father's level of education and occupation as well as HbA1c level (P-value < 0.05). In addition, the frequency index correlated with the frequency of hypoglycemia and the difficulty index correlated with the number of children in the family (P-value < 0.05). CONCLUSION: Parents of children with T1D in Riyadh experience a significant level of stress that may affect the child's glycemic control (Al Dubayee et al, Horm Res Paediatr 88:2019). Assessing the level of stress and providing support for these families has the potential to improve the clinical outcome.
