Background: To determine relationship between the levels of serum Lactate Dehydrogenase (LDH)on admission and prognosis of dengue fever. Methods: Patients (n=62) admitted with the diagnosis of dengue fever were included. On admission, serum LDH levels were measured in all patients and to find relationship we monitored all patients upto discharge. Monitoring was done for vitals, different blood ...

AIM To evaluate the influence of food habits, specifically adherence to the Mediterranean diet, on carotid intima-media thickness (CIMT) and the presence of plaques in HIV-infected patients taking antiretroviral therapy (ART) and non-HIV-infected participants and to determine if HIV infection contributes independently to subclinical atherosclerosis. METHODS We conducted a cross-sectional stud...

A fundamental theorem of Whitney from 1933 asserts that 2-connected graphs $G$ and $H$ are 2-isomorphic, or equivalently, their cycle matroids isomorphic if only can be transformed into by a series operations called switches. In this paper we consider the quantitative question arising Whitney's theorem: Given two 2-isomorphic graphs, transform one another applying at most $k$ switches? This pro...

We consider a two-group randomized clinical trial, where mortality affects the assessment of a follow-up continuous outcome. Using the worst-rank composite endpoint, we develop a weighted Wilcoxon-Mann-Whitney test statistic to analyze the data. We determine the optimal weights for the Wilcoxon-Mann-Whitney test statistic that maximize its power. We derive a formula for its power and demonstrat...

These introductory notes on Whitney towers in 4-manifolds, as developed collaboration with Jim Conant and Peter Teichner, are an expansion of three expository lectures given at the Winter Braids X conference February 2020 Pisa, Italy. Topics presented include local manipulations surfaces 4–space, fundamental definitions related to their associated trees, geometric Jacobi identities, classificat...

PURPOSE To compare the effects of ropivacaine and bupivacaine-lidocaine combination on intraocular pressure, quality of block, and degree of postoperative pain in peribulbar block. METHODS The study group involved 32 patients undergoing elective cataract surgery under peribulbar block. Patients were divided into two groups according to the local anesthetic used: Group 1 (n=16), ropivacaine 0....
