Determination of hepatoprotective effect of Mussaenda erythrophylla in paracetamol induced hepatotoxicity

Background: Hepatotoxicity may be defined as liver injury caused by drugs and chemicals. Drug-induced liver injury is a major reason for withdrawing drugs from a market by Food Drug Administration, and it is based on the fact that drug-induced liver injury is responsible for more than 50% of all cases of acute liver failure. Many studies revealed about the hepatotoxic potential of paracetamol. Hence, the present study has undertaken to evaluate the hepatoprotective effect of Mussaenda erythrophylla (ME) in paracetamol induced hepatotoxicity in Wistar albino rats.Methods: The ethanolic extract ME studied for its hepatoprotective effect on paracetamol induced acute liver damage in Wistar albino rats. The degree of protection was measured using biochemical parameters such as serum glutamate oxalate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), total bilirubin (TBL), superoxide dismutase (SOD), glutathione (GSH) peroxidase (GPx), GSH, and ceruloplasmin levels.Results: Paracetamol treated group had enhanced levels of SGPT, SGOT, TBL (p<0.001) and decreased levels of GSH, SOD, and GPx (p<0.001) when compared with control group. Treatment with silymarin and also 200 mg/kg of MEleaf extract had significantly (p<0.001) brought down the elevated levels of SGPT, SGOT, and TBL and an increase in the levels of GSH, SOD, (p<0.01), GPx and ceruloplasmin (p<0.001).Conclusion: The results showed that ethanolic extract of ME leaf extract possesses significant hepatoprotective activity

Serum Cystatin C in Chronic Kidney Disease: A Case-Control Study

Background: Chronic kidney disease (CKD) is a major public health concern in recent years mainly due to its adverse clinical outcomes. It is most commonly attributed to diabetes mellitus (DM) and hypertension (HTN). Among the several novel biomarkers discovered to detect impaired renal function, serum cystatin C (SCysC) has gained importance. Objectives: The aim of the study was to compare SCysC and serum creatinine (SCr) in CKD subjects and apparently healthy controls. Methods: This case-control study comprising of 120 diagnosed cases of CKD and 40 controls was conducted at a tertiary care hospital. SCr and SCysC levels were estimated using modified Jaffe’s method and particle enhanced immunoturbidimetric method, respectively. Estimated glomerular filtration rate (eGFR) was calculated using CKD EPI formula. Comparison of SCr and SCysC between cases and controls was done using Mann Whitney U test. Pearson’s correlation test was used to study the correlation between variables. Statistical significance was considered at P<0.05. Results: Both SCr and SCysC levels were higher in cases compared to controls (P<0.001). In the group comprising of Stage 1 and Stage 2 CKD subjects, all the subjects showed normal SCr levels, while 96.8% of the subjects showed elevated SCysC levels. SCysC (r=-0.800) showed better correlation than SCr (r=-0.724) with eGFR (P<0.001). A strong correlation was found between SCysC and SCr levels (r=-0.887, P<0.001). Conclusion: SCysC is a good indicator of renal dysfunction and may be used to screen patients with long duration of DM or HTN for CKD

Salivary C-Reactive Protein in Hashimoto's Thyroiditis and Subacute Thyroiditis

C-reactive protein (CRP), an acute-phase reactant, has been identified as a saliva-based biomarker of inflammation. The objective of the study was to estimate and compare salivary CRP levels in Hashimoto's thyroiditis (HT) and Subacute thyroiditis (SAT). The study included 30 HT patients who presented with clinical features of hypothyroidism, 15 SAT patients who presented with clinical features of hyperthyroidism, and 20 healthy age- and sex-matched euthyroid controls. CRP levels in saliva were estimated using an Enzyme-Linked Immunosorbent Assay method with enhanced sensitivity. In HT, the mean salivary CRP levels did not differ significantly from controls. SAT patients had significantly elevated salivary CRP levels compared to HT patients and controls. The rise in salivary CRP levels in SAT patients conceivably reflects the presence of an inflammatory process. Saliva CRP levels appear to serve as inflammatory markers in SAT patients and may aid their clinical evaluation

Context Matters: Intertextuality and Voice in the Early Modern English Controversy about Women

This dissertation examines three clusters of works from the early modern English controversy about women--the debate about the merits and flaws of womankind--in order to argue that authors in the controversy took advantage of the malleability of women's voices to address issues beyond the worth of women. I depart from standard treatments of the controversy by giving priority to the intertextual contexts among works that engage with one another. Attending to the intertextual elements of this genre reveals the metapoetic concerns of the authors and the way such authors fashion their feminine apologists as discursive agents in order to express those concerns. Chapter 1 examines Edward Gosynhyll's sixteenth-century works in tandem with Geoffrey Chaucer's The Legend of Good Women and "The Wife of Bath's Prologue and Tale," arguing that Gosynhyll's revisions of Chaucer--revisions embodied by the feminine apologists in the texts--are integral to his project of establishing the controversy genre as multivalent and dialectical. The resulting metacommentary examines in a new light the age-old rhetorical tradition of exemplarity, a persuasive tool used in diverse literary genres. Chapter 2 considers the way the anonymous play Swetnam the Woman-Hater uses cross-voicing and cross-dressing to establish the performative nature of controversy conventions. In doing so, the play argues for the social benefits of abandoning essentialist logic in favor of gender performance, as such performance makes the role of apologist available to men and women alike. This cluster reconsiders the very processes by which a person--male or female--can be known to others. Finally, I trace John Taylor's use of the marginal woman in his controversy works in order to demonstrate the extent to which Taylor makes these women instrumental in establishing his own poetic and social identity. This project contributes to studies on the English controversy as well as to the field of early modern women and women's writing by arguing that authors found the genre generally and the woman's voice specifically to be fit vehicles for articulating poetic agendas beyond the immediate task of debating the nature of womankind

Impact of an International Nosocomial Infection Control Consortium multidimensional approach on central line-associated bloodstream infection rates in adult intensive care units in eight cities in India

SummaryObjectiveTo evaluate the impact of the International Nosocomial Infection Control Consortium (INICC) multidimensional infection control approach on central line-associated bloodstream infection (CLABSI) rates in eight cities of India.MethodsThis was a prospective, before-and-after cohort study of 35650 patients hospitalized in 16 adult intensive care units of 11 hospitals. During the baseline period, outcome surveillance of CLABSI was performed, applying the definitions of the CDC/NHSN (US Centers for Disease Control and Prevention/National Healthcare Safety Network). During the intervention, the INICC approach was implemented, which included a bundle of interventions, education, outcome surveillance, process surveillance, feedback on CLABSI rates and consequences, and performance feedback. Random effects Poisson regression was used for clustering of CLABSI rates across time periods.ResultsDuring the baseline period, 9472 central line (CL)-days and 61 CLABSIs were recorded; during the intervention period, 80898 CL-days and 404 CLABSIs were recorded. The baseline rate was 6.4 CLABSIs per 1000 CL-days, which was reduced to 3.9 CLABSIs per 1000 CL-days in the second year and maintained for 36 months of follow-up, accounting for a 53% CLABSI rate reduction (incidence rate ratio 0.47, 95% confidence interval 0.31–0.70; p=0.0001).ConclusionsImplementing the six components of the INICC approach simultaneously was associated with a significant reduction in the CLABSI rate in India, which remained stable during 36 months of follow-up

International nosocomial infection control consortium (INICC) report, data summary of 36 countries, for 2004-2009

The results of a surveillance study conducted by the International Nosocomial Infection Control Consortium (INICC) from January 2004 through December 2009 in 422 intensive care units (ICUs) of 36 countries in Latin America, Asia, Africa, and Europe are reported. During the 6-year study period, using Centers for Disease Control and Prevention (CDC) National Healthcare Safety Network (NHSN; formerly the National Nosocomial Infection Surveillance system [NNIS]) definitions for device-associated health care-associated infections, we gathered prospective data from 313,008 patients hospitalized in the consortium's ICUs for an aggregate of 2,194,897 ICU bed-days. Despite the fact that the use of devices in the developing countries' ICUs was remarkably similar to that reported in US ICUs in the CDC's NHSN, rates of device-associated nosocomial infection were significantly higher in the ICUs of the INICC hospitals; the pooled rate of central line-associated bloodstream infection in the INICC ICUs of 6.8 per 1,000 central line-days was more than 3-fold higher than the 2.0 per 1,000 central line-days reported in comparable US ICUs. The overall rate of ventilator-associated pneumonia also was far higher (15.8 vs 3.3 per 1,000 ventilator-days), as was the rate of catheter-associated urinary tract infection (6.3 vs. 3.3 per 1,000 catheter-days). Notably, the frequencies of resistance of Pseudomonas aeruginosa isolates to imipenem (47.2% vs 23.0%), Klebsiella pneumoniae isolates to ceftazidime (76.3% vs 27.1%), Escherichia coli isolates to ceftazidime (66.7% vs 8.1%), Staphylococcus aureus isolates to methicillin (84.4% vs 56.8%), were also higher in the consortium's ICUs, and the crude unadjusted excess mortalities of device-related infections ranged from 7.3% (for catheter-associated urinary tract infection) to 15.2% (for ventilator-associated pneumonia).

Assaying of p53 Autoantibodies in saliva for the detection of oral squamous cell carcinoma. A road not taken.

Autoantibody detection is a promising approach to cancer screening. Serum p53 antibodies have been time tested in various cancers, including oral squamous cell carcinoma (OSCC). This study is aimed to detect and determine the level of p53 autoantibodies (p53-AAbs) in saliva. The association of clinicopathological features among patients with and without OSCC was also explored as a novel method for the detection of autoantibodies. One hundred preoperative saliva samples from patients with histologically confirmed OSCC and a hundred from normal healthy individuals were collected. Anti p53 detection kit assessed levels of salivary p53-AAbs. The cut-off value was 1.3 U/mL by Enzyme-linked immunosorbent assay (ELISA). The p53-AAb levels were expressed in terms of the median and interquartile range (IQR). Fischer's exact test and Chi-square test were used to determine the association with clinicopathological features among patients with OSCC and healthy controls with tobacco consumption habits. Median level of p53-AAb is 0.234 U/mL (IQR 0.18-0.37U/mL) in healthy controls and 0.285U/mL (IQR 0.16-0.58U/mL) in OSCC. p53-AAbs was positive in 15% of 100 patients with OSCC, which was statistically higher (P < 0.001) among OSCC, and controls were negative for p53-AAb. No significant correlation of p53-AAbs with the patient's age, gender, site, clinical staging (TNM), and pathologic grade was observed. However, a significant association was seen between the node involvement and salivary p53-AAbs. Salivary p53-AAb positivity was seen in a higher proportion in OSCC patients than in healthy controls with tobacco consumption, and the levels did differ significantly among OSCC and healthy controls.
