Changes of antioxidant enzymes in the kidney after cardiac arrest in the rat model

Globally, cardiac arrest (CA) is a leading cause of death and disability. Asphyxial CA (ACA)-induced kidney damage is a crucial factor in reducing the survival rate. The purpose of this study was to investigate the role of antioxidant enzymes in histopathological renal damage in an ACA rat model at different time points. A total of 88 rats were divided into five groups and exposed to ACA except for the sham group. To evaluate glomerular function and oxidative stress, serum levels of blood urea nitrogen (BUN) and creatinine (Crtn) and malondialdehyde (MDA) levels in renal tissues were measured. To determine histopathological damage, hematoxylin and eosin staining, periodic acid-Schiff staining, and Masson's trichrome staining were performed. Expression levels of antioxidant enzymes including superoxide dismutase-1 (SOD-1), superoxide dismutase-2 (SOD-2), catalase (CAT), and glutathione peroxidase (GPx) were measured by immunohistochemistry (IHC). Survival rate of the experimental rats was reduced to 80% at 6 h, 55% at 12 h, 42.9% at 1 day, and 33% at 2 days after return of spontaneous circulation. Levels of BUN, Crtn, and MDA started to increase significantly in the early period of CA induction. Renal histopathological damage increased markedly from 6 h until two days post-CA. Additionally, expression levels of antioxidant enzymes were significantly decreased at 6 h, 12 h, 1 day, and 2 days after CA. CA-induced oxidative stress and decreased levels of antioxidant enzymes (SOD-1, SOD-2, CAT, GPx) from 6 h to two days could be possible mediators of severe renal tissue damage and increased mortality rate.

A quasi-experimental study on the effect of a nursery rhyme on the comfort of infants after vaccination in selected barangay health centers in Quezon City / The Health Sciences Journal

INTRODUCTION@#Administration of parenteral medications may cause pain in infants. This study aimed to assess the efficacy of a nursery rhyme in increasing the comfort of infants after vaccination.@*METHODS@#Infants who were brought to six barangay health centers for vaccination were recruited. Infants from three barangay health centers were randomly assigned to the experimental group, while infants from the other three were assigned to the control group. A Filipino nursery rhyme Tatlong Bibe was played to the experimental group. The comfort of each infant was then assessed by a pediatrician prior to, immediately after, and two minutes post-vaccination using the COMFORTB scale. Results were analyzed using independent t-tests.@*RESULTS@#Prior to vaccination, the control and experimental groups had mean COMFORT-B scores of 12.46 and 12.74 (p = 0.634), respectively. The immediate post-vaccination mean COMFORT-B scores were 22.14 and 21.63 (p = 0.420), while the 2 minutes post-vaccination mean COMFORT-B scores were 16.40 and 16.49 (p = 0.927), respectively. There were no significant differences between groups for the three determinations.@*CONCLUSION@#Based on the study results, the nursery rhyme had no significant effect on the comfort of infants after vaccination.

The merits of cytology in the workup for upper tract urothelial carcinoma - a contemporary review of a perplexing issue

Introduction The importance of upper tract cytology for evaluating tumors is unclear. We correlated upper tract cytology with histologic findings in patients who underwent nephroureterectomy for upper tract urothelial carcinoma (UTUC) at a single tertiary care referral center. Materials and Methods 137 patients underwent nephroureterectomy between 2004 and 2012. 18 patients were excluded (benign tumors, atrophic kidneys with the remaining 119 patients serving as our study population). Upper tract cytology from the renal pelvis and/or ureter were retrospectively reviewed and analyzed with final pathology data in the remaining patients with UTUC. Results 57% (68/119) had preoperative upper tract cytology collected. 73% (50/68) patients had abnormal cytology (positive, suspicious) with a sensitivity of 74% (which increased to 90% if atypical included), specificity of 50% and a positive predictive value of 98%. High grade tumors were more common than expected (77% high grade vs. 20% low grade). Abnormal cytology did not predict T stage or tumor grade. Interestingly, positive upper tract cytology was found in all of the UTUC CIS specimen. Conclusions Upper tract cytology has been utilized to support the diagnosis of upper tract urothelial carcinoma. Our data demonstrates that abnormal cytology correlates well with the presence of disease but does not predict staging or grading in these respective patients. .

The Effects of Social Skills Training vs. Psychoeducation on Negative Attitudes of Mothers of Persons with Schizophrenia: A Pilot Study

OBJECTIVE: We compared the effects of two brief psychoeducation programs and social skills training on the negative attitudes of mothers with a son who has schizophrenia. METHODS: 15 mothers with strong negative feelings towards a sons with schizophrenia were assigned by convenience to participate in one of three brief (5 session) group programs at an outpatient clinic: lecture-based psychoeducation, video-based psychoeducation, or social skills training. Assessments using the Patient Rejection Scale were conducted with the mothers at post-treatment, and 3-, 6-, and 9-months later. RESULTS: Mothers in the three groups demonstrated significantly different patterns of changes in their negative attitudes following treatment. Whereas the mothers who received the two psychoeducation interventions showed reductions in rejecting attitudes immediately following the program, their scores gradually increased at the subsequent follow-up assessments. In contrast, the mothers in the social skills training group showed reductions in negative attitudes that were sustained across all of the follow-up assessments. CONCLUSION: Brief social skills training may be more effective than psychoeducation in reducing negative attitudes of parents who have an offspring with schizophrenia.
