The aim of this study was to examine how ibuprofen and paracetamol prevent pain after cold-steel extracapsular tonsillectomy in children. Also, we examined the relation between age, gender, nausea, postoperative bleeding, antibiotic use, type of diet, and postoperative pain intensity and the type of administered analgesic. A prospective study was conducted on 147 children (95 males and 52 females, aged 7-17 years) who underwent tonsillectomy in the Clinical-Hospital Center “Dragiša Mišović” from January 1 to June 30, 2016. The degree of pain was measured using a visual analog scale (VAS). We did not observe any significant differences in postoperative nausea, hospitalization rate postoperative bleeding, and antibiotic use between the paracetamol and ibuprofen groups. A test of within-patient effects showed that VAS scores changed significantly during the postoperative follow-up period ( P = .00), but there were no significant differences between the groups ( P = .778). After 12 hours, 29.3% of the patients on paracetamol and 21.8% on ibuprofen were transferred to a soft diet; after 24 hours, 84.8% of the paracetamol group and 85.5% of the ibuprofen group were on a soft diet (χ 2 test, P < .05). There was a statistically significant correlation between VAS scores measured 4 hours after the surgery and the time of transference to the soft diet (Spearman ρ test, P < .001). The transfer to soft and normal diets was not significantly different between the 2 groups as assessed by the VAS scores (Pearson χ 2 test, P = .565).There is still no consensus on the most effective postoperative pain-control regiment after tonsillectomy. This study showed that satisfactory pain management was achieved equally with both paracetamol and ibuprofen.

Background The endothelial glycocalyx is a vasoprotective barrier between the blood and endothelium. We hypothesized that glycocalyx degradation is present in preeclampsia, a pregnancy‐specific hypertensive disorder characterized by endothelial dysfunction and activation. Methods and Results We examined the sublingual glycocalyx noninvasively using sidestream dark field imaging in the third trimester among women with normotensive pregnancies (n=73), early (n=14) or late (n=29) onset preeclampsia, or gestational diabetes mellitus (n=21). We calculated the width of the glycocalyx that was permeable to red blood cells (called the perfused boundary region , a measure of glycocalyx degradation) and the percentage of vessels that were filled with red blood cells ≥50% of the time (a measure of microvascular perfusion). In addition, we measured circulating levels of glycocalyx components, including heparan sulfate proteoglycans, hyaluronic acid, and SDC1 (syndecan 1), in a subset of participants by ELISA . Repeated‐measures ANOVA was performed to adjust for vessel diameter and caffeine intake. Women with early onset preeclampsia showed higher glycocalyx degradation, indicated by a larger perfused boundary region (mean: 2.14 [95% CI, 2.05–2.20]), than the remaining groups (mean: normotensive: 1.99 [95% CI, 1.95–2.02], P =0.002; late‐onset preeclampsia: 2.01 [95% CI, 1.96–2.07], P =0.024; gestational diabetes mellitus: 1.97 [95% CI, 1.91–2.04], P =0.004). The percentage of vessels that were filled with red blood cells was significantly lower in early onset preeclampsia. These structural glycocalyx changes were accompanied by elevated plasma concentrations of the glycocalyx components, heparan sulfate proteoglycans and hyaluronic acid, in early onset preeclampsia compared with normotensive pregnancy. Conclusions Glycocalyx degradation and reduced microvascular perfusion are associated with endothelial dysfunction and activation and vascular injury in early onset preeclampsia.

Transparent reporting is essential for the critical evaluation of studies. However, the reporting of statistical methods for studies in the biomedical sciences is often limited. This systematic review examines the quality of reporting for two statistical tests, t-tests and ANOVA, for papers published in a selection of physiology journals in June 2017. Of the 328 original research articles examined, 277 (84.5%) included an ANOVA or t-test or both. However, papers in our sample were routinely missing essential information about both types of tests: 213 papers (95% of the papers that used ANOVA) did not contain the information needed to determine what type of ANOVA was performed, and 26.7% of papers did not specify what post-hoc test was performed. Most papers also omitted the information needed to verify ANOVA results. Essential information about t-tests was also missing in many papers. We conclude by discussing measures that could be taken to improve the quality of reporting.

Objective To examine the effects of bowel management on urinary incontinence in patients with spina bifida associated with overactive bladder ( OAB ) and detrusor sphincter dyssynergia ( DSD ). Materials and Methods The research was carried out during the period 2014–2017. A total of 35 patients (group 1) were administered bowel management combined with anticholinergic medication therapy and clean intermittent catheterization ( CIC ) and 35 patients (group 2) were treated only with anticholinergic medication therapy and CIC . Bowel management included daily enema, laxative application and a special diet, with the aim of treating constipation, evaluated according to the Roma III criteria and echosonographically determined transversal rectal diameter. The effects of the administered bowel management on urinary incontinence were assessed according to the mean dry interval between two CIC s for all patients. All patients were followed up for 1 year, during which data were prospectively collected. Results There was no statistically significant difference with regard to age, gender and baseline clinical features between the two groups. In group 1, the mean ± sd dry interval between two CIC s was 150.0 ± 36.4 min, and group 2 it was 101.3 ± 51.6 min. There was a significant difference in urinary incontinence, i.e. in the mean dry interval, between the two groups ( P < 0.001). Conclusion Administering bowel management considerably increased the mean dry interval, thus greatly alleviating the symptoms of urinary incontinence. For this reason, bowel management should form an integral part of the treatment of patients with spina bifida and OAB and DSD .

Abstract Objective: Experimental models suggest estrogen has a renoprotective effect, but human studies show variable results. Our objective was to study the association of hormone therapy (HT) and albuminuria in postmenopausal women and to synthesize the results with outcomes from prior studies. Methods: We analyzed data from postmenopausal women who participated in the second study visit (2000-2004) of the Genetic Epidemiology Network of Arteriopathy (GENOA) study. The exposure was self-reported HT use and the outcome was albuminuria (urine albumin-to-creatinine ratio >25 mg/g creatinine). We also conducted a systematic review and meta-analysis on the association of HT and urine protein in postmenopausal women. Continuous and dichotomous measures of protein excretion were converted to a standardized mean difference (SMD) for each study. Results: In the GENOA cohort ( n = 2,217), there were fewer women with albuminuria among HT users than nonusers (9% vs 19%, P < 0.001). HT use was associated with decreased odds of albuminuria (odds ratio 0.65, 95% confidence interval (CI), 0.45-0.95), after adjusting for significant differences in age, race, education, comorbidities, and the age at and cause of menopause. The SMD of the effect of HT on urine proteinuria/albuminuria in the randomized control trials ( n = 3) was 0.02 (95% CI, −0.29 to 0.33) and −0.13 (95% CI, −0.31 to 0.05) in the observational studies ( n = 9). There was significantly less albuminuria among HT users (SMD −0.15, 95% CI, −0.27 to −0.04) in the 9 studies that only reported albuminuria as an outcome and in the 10 studies with a comparator arm (SMD −0.15, 95% CI, −0.26 to −0.04). Conclusions: HT is associated with decreased odds of albuminuria, but some of the observed benefits may be related to reported outcomes, the presence of a comparator arm, and the type of study design.

Abstract Objective Streamlining the diagnosis is a key factor in improving the treatment outcomes for breast cancer. The aim of this study was to determine factors influencing time to seeking medical advice and treatment onset in women who are diagnosed with breast cancer in Serbia. Methods The study was a multicenter, cross‐sectional national survey, performed at 10 oncology centers in Serbia. Time intervals spent throughout the complex diagnostic pathway were evaluated using a validated questionnaire administered to women with breast cancer ( n = 800). Total interval (TI) was determined using predefined time scales, including one referring to patient interval (PI), and several related to health care system interval (SI). Results Mean PI, SI, and TI were 4.5, 9.2, and 12.9 weeks, respectively; 20% of patients had a PI>12 weeks. Based on the multivariate regression model, longer PI was associated with perceived lack of time and personal disregard or trivialization of detected symptoms and signs. Women who were supported by family members or friends and had at least a secondary level education tended to have a shorter PI. Longer PI was correlated with a longer SI, while regular self‐examination, having been diagnosed by an oncologist, and living in a major city were associated with shorter SI. Conclusions Several factors, related to psychological, demographic, behavioral, and health system characteristics, determined both the time to seeking medical advice and treatment onset for breast cancer. These findings support review and refining of national strategies and policies to promote early detection, diagnosis, and treatment of breast cancer.

We performed a prospective, longitudinal study of pregnant women presenting to their first obstetrics visits to characterize the changes in spot urine protein-to-creatinine (UPCR) and albumin-to-creatinine ratios (UACR) in normotensive pregnancies, as well as identify clinical characteristics associated with isolated proteinuria and preeclampsia. We measured spot urinary albumin, protein, and creatinine at the first prenatal visit, end of the second trimester, and at delivery. In the normotensive pregnancies ( n = 142), we found that from the beginning of pregnancy to delivery, UACR increased by a median [interquartile range (IQR)] of 14.7 mg/g Cr (3.74–51.8) and UPCR by 60 mg/g Cr (30–130) ( P < 0.001 for both changes). Isolated proteinuria (defined as UPCR > 300 mg/g Cr in the absence of hypertension) was identified in 19/142 (13.4%) normotensive pregnancies. Increases in systolic and diastolic blood pressure from early pregnancy to delivery and increases in UACR from early to midpregnancy were associated with isolated proteinuria at delivery. Twelve women developed preeclampsia. Nulliparity, early, and midpregnancy diastolic blood pressures were strongly associated with the development of preeclampsia, but early changes in UACR were not. In conclusion, women who develop isolated proteinuria at delivery have a larger increase in blood pressure than women without proteinuria and have a “microalbuminuric” phase earlier in gestation, unlike women who develop preeclampsia. These findings suggest a different mechanism of urine protein excretion in women with isolated proteinuria as compared with women with preeclampsia, where proteinuria has a more abrupt onset.

Renal histologic expression of the podocyte-specific protein, nephrin, but not podocin, is reduced in preeclamptic compared with normotensive pregnancies. We hypothesized that renal expression of podocyte-specific proteins would be reflected in urinary extracellular vesicles (EVs) of podocyte origin and accompanied by increased urinary soluble nephrin levels (nephrinuria) in preeclampsia. We further postulated that podocyte injury and attendant formation of EVs are related mechanistically to cellfree fetal hemoglobin (HbF) in maternal plasma. Our study population included preeclamptic ( n =49) and normotensive ( n =42) pregnant women recruited at delivery. Plasma measurements included HbF concentrations and concentrations of the endogenous chelators haptoglobin, hemopexin, and α 1- microglobulin. We assessed concentrations of urinary EVs containing immunologically detectable podocyte-specific proteins by digital flow cytometry and measured nephrinuria by ELISA. The mechanistic role of HbF in podocyte injury was studied in pregnant rabbits. Compared with urine from women with normotensive pregnancies, urine from women with preeclamptic pregnancies contained a high ratio of podocin-positive to nephrin-positive urinary EVs (podocin + EVs-to-nephrin + EVs ratio) and increased nephrinuria, both of which correlated with proteinuria. Plasma levels of hemopexin, which were decreased in women with preeclampsia, negatively correlated with proteinuria, urinary podocin + EVs-to-nephrin + EVs ratio, and nephrinuria. Administration of HbF to pregnant rabbits increased the number of urinary EVs of podocyte origin. These findings provide evidence that urinary EVs are reflective of preeclampsia-related altered podocyte protein expression. Furthermore, renal injury in preeclampsia associated with an elevated urinary podocin + EVs-to-nephrin + EVs ratio and may be mediated by prolonged exposure to cellfree HbF.

Glomerular damage is common in preeclampsia (PE), but the extent and etiology of tubular injury are not well understood. The aim of this study was to evaluate tubular injury in patients with PE and to assess whether it predates clinical disease. We performed a prospective cohort study of 315 pregnant women who provided urine samples at the end of the second trimester and at delivery. This analysis included women who developed PE ( n = 15), gestational hypertension (GH; n = 14), and normotensive controls (NC; n = 44). Urinary markers of tubular injury, α1-microglobulin (A1M), retinol-binding protein (RBP), kidney-injury molecule-1 (KIM1), complement C5b-9, tissue inhibitor metalloproteinase-2 (TIMP-2), and insulin-like growth factor binding protein-7 (IGFBP-7) were measured by enzyme-linked immunosorbent assay (ELISA) and reported in relation to urine creatinine concentration. Second-trimester concentrations of all markers were similar among groups. At delivery, A1M concentrations were higher in the PE group than in the GH and NC groups as an A1M/creatinine ratio >13 (66.7, 8.3, and 35%, respectively, P = 0.01). Concentrations of C5b-9 were higher in the PE group than in the GH and NC groups (medians 9.85, 0.05, and 0.28 ng/mg, respectively, P = 0.003). KIM1, RBP, TIMP-2, and IGFBP-7 concentrations did not differ among groups at delivery. In conclusion, proximal tubular dysfunction, as assessed by A1M and C5b-9, developed during the interval between the end of the second trimester and delivery in patients with PE. However, this was not matched by abnormalities in markers previously associated with tubular cell injury (KIM-1, IGFBP-7, and TIMP-2).
