Equilibration Rate

Background Criteria for how to assess removal rate of inorganic phosphorous (iP) in peritoneal dialysis (PD) and whether iP removal differs between different PD modalities are debated. Methods In a cross-sectional study, 73 prevalent patients on continuous ambulatory PD (n = 16), continuous cyclic PD (n = 8) or automated PD (n = 49) with mean age 54 (range, 18–87) years, 46 males, underwent standard peritoneal equilibration test (PET) and 24-hour collection of dialysate with measurements of iP, urea and creatinine in all samples and bags. There were 11 slow, 53 average, and 9 fast transporters. Results D/P ratios for iP and creatinine at 4 h of PET were strongly correlated (ρ = 0.86, p<0.0001). Allocation of patients into slow, average and fast transporters according to D/P ratios for iP and creatinine was essentially similar. Whereas the weekly peritoneal clearance of iP (30.8 ± 16.6 L/wk) was lower than that of creatinine (38.4 ± 14.9 L/wk), clearances were strongly correlated (ρ = 0.89, p<0.0001). The correlation between peritoneal weekly clearance of iP and urea KT/V was however weak (ρ = 0.56, p<0.0001. CAPD patients had higher iP clearance than APD patients, 43.2 ± 14.9 versus 24.7 ± 13.4 L/wk (p<0.05); however, serum iP concentrations did not differ. Conclusions Creatinine is a good surrogate marker for phosphate removal, both as assessed by PET and by 24 hours' clearance, in different PD modalities. Therefore, a separate PET scale for phosphate may not be needed. iP removal was greater with CAPD than APD but serum phosphate levels did not differ.

Significant Difference

Digit ratio (2D:4D) denotes the relative length of the second and fourth digits. There are contradicting reports on its relationship with ethnicity/race, whereas convincing studies show it is related to obesity. This cross-sectional study was undertaken to demystify ethnic difference in 2D:4D ratio and to analyze its relationship with obesity among adults in Ilorin Nigeria. The cross-sectional study included 701 individuals. Finger lengths were measured with electronic calipers and other anthropometric traits were measured with standard procedure. Student t test and one-way ANOVA were used to detect differences among groups and relationship was computed with Pearson correlation. The receiver operator characteristic curves were used to detect the diagnostic effect of 2D:4D for obesity. The obtained results showed sexual dimorphism in 2D:4D ratio and other anthropometrics at p < 0.01. Obesity was associated with significantly higher mean of 2D:4D in both genders (female 0.9814 ± 0.012:0.9700 ± 0.012; male 0.9700 ± 0.010:0.9592 ± 0.010 at p < 0.001). The area under the curve was 0.753 (95% CI 0.677-0.829, p < 0.01) and 0.798 (95% CI 0.756-0.804, p < 0.01) in female and male R2D:4D respectively for obesity, implying that 2D:4D might be a surrogate marker for obesity in future.  No significant difference was found in 2D:4D among different ethnic groups studied (p >0.05); this result proved that there was no ethnic specificity in 2D:4D ratio among study’ participants. Thus, it can be reported that the digit ratio was related to high 2D:4D, but this cannot be said for different ethnic groups. The results imply that 2D:4D might be a good surrogate indicator for obesity, but not ethnicity.

Objective To evaluate fibrinogen concentration of relapsing neph-rotic syndrome (NS) in children, and to investigate relationshipbetween fibrinogen with albumin and cholesterol.Methods A cross-sectional study among NS patients admitted topediatric outpatient clinic and pediatric ward at Sanglah Hospital,Denpasar, from November 1, 2003 to January 31, 2004. All pa-tients were evaluated for clinical and laboratory findings of relapseand remission, including edema, proteinuria, serum albumin, totalcholesterol, as well as total platelet count and fibrinogen concen-tration to evaluate coagulation parameters in nephrotic patients.Results There were 36 patients with the mean age of 7.4 (SD 2.3)years included in this study. Mean fibrinogen concentration in re-lapse state was 671.8 (SD 102.7) mg/dl, while in remission statewas 255.2 (SD 50.5 mg/dl); the mean difference was 416.6 mg/dl(95% CI 362.9;470.4; P<0.001). Fibrinogen was inversely andstrongly correlated with serum albumin concentrations (r=-0.91;P<0.001). Fibrinogen was positively and strongly correlated to to-tal cholesterol (r=0.80; P<0.001). Using multiple regression analy-sis, it was shown that only relapse/remission status was signifi-cantly associated with fibrinogen concentration (P<0.001).Conclusion Fibrinogen status is significantly correlated with re-lapse and remission status of NS in childhood patients.

Purpose. To investigate the association of automated visual field (VF) reliability indices (false positive [FP], false negative [FN], and fixation loss [FL]) and sleep quality, VF experience, and age. Methods. Prospective, cross-sectional study. Adult patients (age ≥ 18 years) completing automated VF testing were invited to participate. Baseline participant characteristics were obtained, and all participants were asked to complete the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Nonparametric Spearman correlations and logistical regression models were performed. Results. 63 patients were enrolled. Lower PSQI score was correlated with higher percentage (%) FL in the right eye (p=0.03). Fewer prior VF was significantly correlated with higher %FP in the right eye (p=0.008). Older age was significantly correlated with higher %FN in the left eye (p=0.01). Greater mean deviation (MD) and pattern standard deviation (PSD) were strongly correlated with higher %FN in the right (p=0.02 and 0.002, resp.) and left eyes (p=0.01 and 0.02, resp.). Conclusion. In this prospective, cross-sectional study, worse MD and PSD are strongly correlated with increased FN in both eyes. Increased FN in the left eye associated with older age might be attributable to test fatigue. Worse sleep quality is associated with decreased FL in the right eye.

Objective.A cross-sectional study was undertaken to determine the prevalence of axial gout in patients with established gouty arthritis and to analyze clinical, laboratory, and radiological correlations.Methods.Forty-eight subjects with a history of gouty arthritis (American College of Rheumatology criteria) for ≥ 3 years under poor control were included. Subjects underwent history, physical examination, laboratory testing, and imaging studies, including radiographs of the hands and feet and computerized tomography (CT) of the cervical and lumbar spines and sacroiliac joints (SIJ). Patients with characteristic erosions and/or tophi in the spine or SIJ were considered to have axial or spinal gout.Results.Seventeen patients (35%) had CT evidence of spinal erosions and/or tophi, with tophi identified in 7 of the 48 subjects (15%). The spinal location of axial gout was cervical in 7 patients (15%), lumbar in 16 (94%), SIJ in 1 (6%), and more than 1 location in 14 (82%). Duration of gout, presence of back pain, and serum uric acid levels did not correlate with axial gout. Extremity radiographs characteristic of gouty arthropathy found in 21 patients (45%) were strongly correlated with CT evidence of axial gout (p < 0.001). All patients with tophi in the spine had abnormal hand or feet radiographs (p = 0.005).Conclusion.Axial gout may be a common feature of chronic gouty arthritis. The lack of correlation with back pain, the infrequent use of CT imaging in patients with back pain, and the lack of recognition of the problem of spinal involvement in gouty arthritis suggest that this diagnosis is often missed.

Introduction: Metabolic syndrome (MS) is an independent risk factor, which affects the development of chronic kidney disease, so the glomerular filtration rate (GFR) as an indicator of glomerular function in patients with and without MS who attended the outpatient clinic “los Grillitos, sector Caña de Azucar”. Materials and Methods: A comparative, correlational, cross-sectional study was conducted in a non-probability sample of convenience consisting of 60 patients with MS diagnosed according to the criteria Panel ATP III, and 60 apparently healthy individuals, whom the GFR was determined by the Cockcroft-Gault as well as clinical and biochemical parameters for the diagnosis of MS. Results: Out of the total patients evaluated, 37 (30.7%) showed alterations that put them in grades G2 and G3 system risk stratification of CKD, of these 18 and 19 corresponded to patients with and without MS respectively. Glomerular Hyperfiltration (> 120 mil / min) it was found in both groups 28 (46.7%) and 24 (40%) cases of patients with and without MS respectively. The glomerular function was strongly correlated with abdominal obesity and high levels of stress arterial. As for the number of criteria and its relationship to the level of kidney damage present, not a firm to increase the latter with respect to the first (p=0.385) trend was observed. Conclusion: The change in the glomerular function is not directly related to the MS but with its components, specifically abdominal obesity and hypertension.

Objective To determine if peritoneal dialysis modality has an impact on protein losses in dialysate. Design Retrospective, cross-sectional study. Patients 190 patients who had selected peritoneal dialysis were classified into one of four transport categories (high, high-average, low-average, or low) based on standard peritoneal equilibration test results. Patients were then assigned to continuous ambulatory peritoneal dialysis (CAPD) or nightly intermittent peritoneal dialysis (NIPD) based on membrane transport characteristics and individual preferences. Results Patients with similar membrane transport characteristics had essentially no differences in dialysate protein and albumin losses whether treated with CAPD or NIPD. Conclusions Although high transporters may be better managed with short -dwell therapies such as nocturnal intermittent peritoneal dialysis or daily ambulatory peritoneal dialysis, consistent marked decreases in protein losses cannot be cited as a benefit of NIPD over CAPD.

We performed a cross-sectional study within a specialised respiratory inpatient unit assessing 25 nurses’ [85% female, 8.0 ± 7.9 (mean ± SD) years’ experience in nursing] confidence in providing inhaler device education using a self-reported questionnaire, and their competency (% correct steps) in using eight different inhaler devices. Sixteen percent of participants were ‘not confident’ providing inhaler education, while 84% were ‘moderately’ or ‘extremely’ confident. The mean (±SD)% correct steps for all devices was 47 ± 17%. There was no correlation between % correct steps and nursing years (r = 0.21, p = 0.31), or ‘confidence’ with providing inhaler education (r = 0.02, p = 0.91) but % correct steps strongly correlated with number of individual device prescriptions within the hospital in the preceding year (r = 0.78, p = 0.039). Most respiratory nurses felt confident in teaching inhaler technique but their overall demonstrated ability to correctly use inhalers was poor, especially for less frequently prescribed devices within our hospital. Regular assessment and ongoing education on correct inhaler technique for respiratory nurses is necessary to optimise all device usage by nurses, irrespective of experience or confidence.

The present study aims to identify and compare the psychological factors that may contribute to an individual’s predisposition for developing gallstone disease. Totally, 10,192 respondents to our specially designed triple questionnaire containing 614 psychological and medical items to assess the psychological features associated with gallstone disease were included in this cross-sectional study. The psychological items most strongly correlated with gallstone disease were those reflecting the tendency to self-sacrifice, hard-work, care for others, responsibility and discontent. At the heart of the gallstone-associated mindset seems to reside the inclination to frustrate one’s desires/interests for the sake of fulfilling one’s familial/social/professional duties/responsibilities.

Introduction: Cervical cancer is the most common cancer among females. P16 is the surrogate marker for cervical carcinoma. This study aimed to evaluate the association of P16 marker with clinic-pathological parameters in squamous cell carcinoma of uterine cervix. Methods: This was a cross-sectional study. Histological confirmed cases of squamous cell carcinoma (SCC) of cervix were considered. All cases were evaluated for IHC P16 expression as per lower anogenital squamous terminology (LAST) criteria and correlated with clinico-pathological parameters. The data was analyzed by SPSS software version 22. Results: Out of 75 cases, P16 biomarker expression was block positive, ambiguous and negative in 67 (89.3%), 5 (6.6%), and 3 (4%) cases, respectively. There was a significant association between P16 expression and age (p = 0.005). All cases between 30-59 years of age showed block positivity. There was no significant association between P16 expression and age at marriage (p = 0.951), age at menopause (p = 0.311), parity (p = 0.554), clinical symptoms/signs, stage of disease (p = 0.28), or histopathological grade (p = 0.877). Maximum expression was seen between 40-44 years. Moreover, all cases having 1 & 2 parity showed block positivity and all stage I cases showed block positivity. Conclusion: P16 biomarker was significantly expressed in cervical cancers of the relatively younger age group and those with early stage of disease.
