Background: Preeclampsia is characterized by hypertension and proteinuria with the onset after 20 weeks of gestation. Globally 14.5% of maternal death is due to preeclampsia with fetal complications. National Record of Family Health Division Nepal shows prevalence rate of preeclampsia as 8.5%. The gold standard 24 hours urine protein evaluation test is time consuming for the diagnosis of preeclampsia and can increase complications to mother and fetus. Instant diagnosis and prompt management is needed. Objective of this study was to determine the accuracy of urinary protein/creatinine (P/C) ratio test and correlate random urinary (P/C) ratio with twenty-four hours urinary protein in detecting preeclampsia. Methods: A cross sectional study was carried out conveniently selecting 130 samples of preeclampsia from Obstetrics and Gynaecology Department of National Medical College Teaching Hospital, Birgunj, Nepal. Out of 130 samples all met the inclusion criteria. Both twenty-four hours urine protein and P/C ratio were performed for each case. Correlation between two tests and accuracy of the test was performed using SPSS V 16. Results:  This study showed protein creatinine ratio is as capable as 24 hours protein urine to diagnose pregnant mother with preeclampsia. Spot P/C ratio provides effortless result with high validity and reliability. Conclusion: This study showed protein creatinine ratio is as capable as 24 hours protein urine to diagnose pregnant mother with preeclampsia. Spot P/C ratio provides effortless result with high validity and reliability. Keywords: Preeclampsia, 24 hours urinary protein, Receiver Operator characteristic curve (ROC), Area under the curve (AUC)

Aim: To assess the diagnostic accuracy of spot urine protein-creatinine ratio for detection of proteinuria in Preeclampsia. Methods: Cross Sectional Descriptive Study was conducted in a total of 38 pregnant women in Paropakar Maternity and Women’s Hospital in study period of 3 month. The correlation between protein- creatinine ratio in spot urine samples and urinary protein excretion in 24-hour collections were analyzed. Results: Comparison of 24 hours urinary protein and protein- creatinine ratio in women with preeclampsia shows a significant correlation (r=0.911, p<0.0001). The cut-off protein-creatinine ratios which gave maximum area under the curve for 300mg protein for 24hrs was 0.27 (sensitivity: 94.6%, specificity: 100%, PPV: 100%, NPV: 33.3%); 2000 mg urine protein excretion was 2.1 (sensitivity and specificity of 100%); 3000mg protein excreted for 24hours was 3.0 (sensitivity: 83.3%, specificity: 92.3%, PPV: 83.3%, NPV: 93.3%. Area under the ROC for 24hours urine total protein of >300mg, >2000mg and >3000mg/day were 0.946 (95%CI 0.873-1.019), 1 (95% CI 1.00-1.00) and 0.957 (95%CI 0.897- 1.016) respectively. Conclusions: Spot urine protein-creatinine ratio is as accurate as to 24 hours urine protein determination of proteinuria in Preeclampsia.

CONTEXT: Malnutrition in cirrhotic patients with end-stage disease is common, and the degree of nutritional debilitation can play an important role in the pathogenesis of complications and cause a negative impact on prognosis. However, it involves difficulties and controversies regarding the identification of the best nutritional assessment method. OBJECTIVE: To identify a method that provides a safe and effective nutritional diagnosis. METHODS: Cross-sectional study with 129 cirrhotic patients. Anthropometric measurements, subjective global assessment, hand grip strength and bioelectrical impedance. RESULTS: Through phase angle of bioelectrical impedance analysis (BIA) method, significant associations with Child-Pugh (P = 0.008), age group and gender were observed. The ROC (receiver operator characteristic) curve was generated to determine the best cutoff point of the phase angle of cirrhotic patients, serving as one of the reference parameters for the nutritional assessment with bioimpedance in this study, considering the classification through Child-Pugh score as the reference standard for the clinical conditions of patients with cirrhosis. CONCLUSIONS: The assessment through bioelectrical impedance presented a statistically significant correlation with Child-Pugh score. The identification of phase angle of 5.44º is the new parameter suggested for the classification of the nutritional conditions of cirrhotic patients.

Background: The aim of the study was to evaluate the ability of the random urine P/C ratio to predict significant proteinuria, as well as to introduce a diagnostic test for pre-eclampsia which will avoid the inconvenience and time consumption of 24-hour urine protein collection. The objective of this study was to compare spot urine protein- creatinine ratio with 24-hour urine protein for estimation of proteinuria in pre-eclampsia.Methods: A total of 50 pregnant women with pre-eclampsia were prospectively studied for proteinuria in Rajarajeswari medical college and Hospital Bangalore for a period of 9 months from September 2018 to May 2019. Spot urine specimens for measuring P/C ratio were obtained immediately before 24-hour urine collection. The correlation between the spot urine P/C ratio and urinary protein excretion in the 24-hour collections was examined using the Spearman correlation test.Results: PCR at a cut off value 0.15 g/mmol had sensitivity and specificity of 96.6% and 55% respectively. In prediction of proteinuria of 300 mg/24 hr positive predictive value and negative predictive value 76.3% and 91.6% respectively.Conclusions: We found that there was a strong correlation between 24-hour urine protein excretion and spot urine protein creatinine ratio in pre-eclamptic women. Spot PCR can be used as a reasonable alternative to 24-hour urine protein test which is a cumbersome.

Abstract Objective Performance validity research has emphasized the need for briefer measures and, more recently, abbreviated versions of established free-standing tests to minimize neuropsychological evaluation costs/time burden. This study examined the accuracy of multiple abbreviated versions of the Dot Counting Test (“quick” DCT) for detecting invalid performance in isolation and in combination with the Test of Memory Malingering Trial 1 (TOMMT1). Method Data from a mixed clinical sample of 107 veterans (80 valid/27 invalid per independent validity measures and structured criteria) were included in this cross-sectional study; 47% of valid participants were cognitively impaired. Sensitivities/specificities of various 6- and 4-card DCT combinations were calculated and compared to the full, 12-card DCT. Combined models with the most accurate 6- and 4-card combinations and TOMMT1 were then examined. Results Receiver operator characteristic curve analyses were significant for all 6- and 4-card DCT combinations with areas under the curve of .868–.897. The best 6-card combination (cards, 1-3-5-8-11-12) had 56% sensitivity/90% specificity (E-score cut-off, ≥14.5), and the best 4-card combination (cards, 3-4-8-11) had 63% sensitivity/94% specificity (cut-off, ≥16.75). The full DCT had 70% sensitivity/90% specificity (cut-off, ≥16.00). Logistic regression revealed 95% classification accuracy when 6-card or 4-card “quick” combinations were combined with TOMMT1, with the DCT combinations and TOMMT1 both emerging as significant predictors. Conclusions Abbreviated DCT versions utilizing 6- and 4-card combinations yielded comparable sensitivity/specificity as the full DCT. When these “quick” DCT combinations were further combined with an abbreviated memory-based performance validity test (i.e., TOMMT1), overall classification accuracy for identifying invalid performance was 95%.

Abstract Objective The Boston Naming Test (BNT) has recently been proposed as an embedded performance validity test (PVT) with high specificity/low sensitivity; however, this has not been replicated. This study therefore aimed to cross-validate findings in a mixed clinical neuropsychiatric sample. Method This cross-sectional study of 136 primary monolingual English-speaking patients who completed the BNT during outpatient evaluation was 57% female/43% male, 38% Caucasian, 39% African American, 16% Hispanic, and 6% Asian with mean age of 47.7 years (SD = 16.6) and mean education of 14.0 years (SD = 2.7). In total, 109/136 (80%) were classified as valid and 27/136 (20%) as invalid based on 4 independent criterion PVTs. Results Respective mean BNT raw/T-scores were 49.5 (SD = 9.2)/45.3 (SD = 10.9) for the valid group and 45.8 (SD = 8.2)/41.1 (SD = 7.8) for the invalid group. Analyses of variance fell just above significance for both BNT raw F(1, 134) = 3.75, p = .05 and T-scores F(1, 134) = 3.55, p = .06. Receiver operator characteristic curve analysis for the raw score was significant, with an area under the curve (AUC) of .67 (p &lt; .01) and an optimal cutoff of ≤ 35 (4% specificity/90% sensitivity). BNT raw scores remained significant after removing bilingual participants, (AUC = .68; p &lt; .01), with identical psychometric properties. In contrast, analysis of BNT T-scores (AUC = .61; p = .08) were nonsignificant. Conclusions Overall, results showed that the BNT cannot psychometrically distinguish valid versus invalid performance and therefore has questionable utility as a PVT in a mixed clinical setting. Findings contribute to a growing literature base cautioning against the indiscriminate use of measures of actual cognitive ability as validity indicators, particularly in populations with cognitive impairment.

Background: Quantification of proteinuria is usually predicted upon 24-hour urine collection. Multiple factors influence urine collection and the rate of protein and creatinine excretion. A spot urine protein-creatinine (P-C) ratio has been shown over the years to be a reliable alternative to the 24-hour collection for detection and follow up of proteinuria. The objective of the study was to evaluate the accuracy of urine protein creatinine ratio (UP/UC) in a spot sample for quantitative measurement of proteinuria in comparison with 24 hours urinary protein excretion in children of nephrotic syndrome having normal Glomerular Filtration Rate (GFR). Methodology: This was a prospective study conducted in the department of paediatrics, Sir Salimullah Medical College & Mitford Hospital Dhaka over a period of six months from January 2003. Fifty cases of Nephrotic syndrome were included who were on initial attack and relapse cases noted down into the proforma with respect to history, examination and investigation. All the patients were advised regarding 24 hours urine collection. They were asked to give a 24 hours urine sample starting at 9.00 am for total protein excretion rate. A spot urine sample was obtained and urine protein/creatinine ratio was calculated. The data was analyzed by linear regression and by calculating the correlation coefficient between urinary protein/ creatinine ratio and 24-hour urinary protein. Results: Sample size was fifty. Urine total protein in a timed 24-hour sample of nephrotic syndrome patients was in the range of 300-3150mg/m2/hour with the mean value of 1725 mg/m2/hour. While as U(Pr/Cr) ratio ranged from 3.1-27.5 with the mean value of 15.2. A significant correlation was found between timed 24-hour urinary protein and UP/UC ratio (r=0.622, p=<.001.) Conclusions: Spot urine protein-creatinine ratio is highly reliable and rapid test for quantification of proteinuria in children with nephrotic syndrome.
