RESUMO
Background: A high dose of statin is used to obtain an intensive lipid-lowering in stroke patients, even in patients with normal lipid levels. There are limited data on effect of dosage of statins and functional outcome in stroke patients. Objectives: To compare serum cholesterol levels with severity of stroke measured by infarct volume. To compare functional outcome measured by mRS at day 90 with the dose of statin. Materials and Methods: This retrospective observational study was conducted in KMC Hospital Manipal, India between 2016 and 2018. Result: A total of 100 consecutive patients were included in the study, out of which 60 (60.0%) were males. Hyperlipidemia was present in 65 (65.0%) patients. On comparing the serum cholesterol levels with infarct volume using MRI, patients with low volume of ≤70 ml had higher mean serum total cholesterol concentration (223.83 mg/dl), whereas patients with high volume of >70 ml had low mean cholesterol level (218.70 mg/dl). The patients were divided into those who received low dose (≤20 mg) versus high dose (≥40 mg equivalent) of Atorvastatin. On comparing the mRS values at baseline and on day 90 with the dose of statins, patients who received a higher dosage had a statistically significant fall in mRS (p-0.045) at day 90. Conclusion: It was found that serum cholesterol levels were inversely related to the stroke severity. However, a higher the dose of statins resulted in better functional outcome and survival in post-stroke patients, possibly due to its neuroprotective effect.

Introduction: Diffusion-weighted image or DWI is commonly used to provide valuable and diverse information on acute stroke in tertiary care hospitals. DWI is a sensitive and accurate method for identifying the infarct core and can expose the area of cerebral infarction within a few hours of onset. This systematic review is planned to evaluate the measurement of stroke volume on DWI and correlate it with functional outcomes (modified ranking scale). Method: We have adhered to the PRISMA-P checklist to report this systematic review protocol. PubMed, Web of Science, Scopus, and TRIP (Turning Research into Practice) databases will be searched. Two independent reviewers will screen the records, extract data, and critically appraise the studies. A checklist for critical appraisal will be applied for data abstraction, and data extraction will be done using predictive modeling for systematic reviews. The risk of bias will be measured by the Prediction Model Risk of Bias Assessment Tool (PROBAST). The meta-analysis will be considered only if included studies have adequate data, and STATA statistical package version 13.1 will be used for performing a meta-analysis. A narrative synthesis will be performed if meta-analysis is not possible. Ethics and Dissemination: As this review will focus on secondary information, there is no ethical consideration required. We will disseminate our findings by publishing our analysis in a peer-reviewed journal. Protocol Registration: In Prospective Register of Systematic Reviews (CRD42019141840).
RESUMO
BACKGROUND: The study aims at the comparison and correlation of serum levels of fructosamine and erythrocyte Na+/ K+ ATPase in Gestational diabetes mellitus (GDM) and Non Gestational Diabetes Mellitus (Non GDM). METHODS: A total of 326 samples were divided into 4 groups. Pregnant women between the age group of 2040 years who gave samples for Oral Glucose Tolerance Test (OGTT) were included as the subjects. Anonymized and left over fasting and 2 hours' samples were collected from biochemistry laboratory, Kasturba Hospital, Manipal. RESULTS: In the comparison of fructosamine levels in GDM and Non GDM, fructosamine was found to be significant (p value<0.001) in both fasting and 2 hours (G2) blood glucose condition. Na+/ K+ ATPase did not show any significant variation between the groups.Correlation was not significant between the parameters. CONCLUSION: Fructosamine showed significant increase when compared between the groups, whereas significant correlation is not obtained between the parameters. Thus, the use fructosamine as a diagnosis tool becomes inconclusive. Further studies must be carried out to identify a marker which reduces the interferences observed in fructosamine and to find out the exact relationship between hyperglycaemia and Na+/ K+ ATPase activity.
