Inpatient Burden of Neurological Disorders: A Route Map for Allocation of Resources and Postgraduate Training.

Introduction There are limited data regarding the profile of inpatient neurological disorders in India. Understanding the spectrum of diseases and the profile of patients admitted in an inpatient setting will help to streamline services, allocate resources, develop management protocols, design curricula, and improve training programs of postgraduate students in neurology training. Objective The objective of this study is to study the profile of inpatient neurological disorders in 1000 consecutive patients admitted to a tertiary care neurological center. Methods Data from 1000 consecutive inpatients admitted to the Neurology Department at St. John's Medical College Hospital, Bengaluru from January 2018 to October 2018 were collected from the medical records. The data obtained from the case records were entered into a Microsoft Excel spreadsheet for descriptive analysis. Results The average age of the patients was 48 years (±18.18) and 606 of the 1000 patients were males. Strokes, including arterial and venous strokes, formed the major inpatient caseload, accounting for 48.7% of cases. Of these, 84% had ischemic arterial strokes, 7.4% had intracranial hemorrhage, and 8.4 % had cerebral sinus venous strokes; 19.3% of patients were admitted for seizures while 8.2% of patients were admitted for headache. Meningitis was diagnosed in 5.2% of patients; 4.8% of patients had central nervous system demyelinating and autoimmune diseases. A number of other diagnoses comprised less than 2.5% each and included movement disorders, peripheral nerve, spine and nerve roots disorders, neuromuscular diseases, neurodegenerative diseases, and medical and functional illness. Conclusion The most common disorders in the inpatient setting are stroke, seizure, headache, meningitis, and autoimmune/demyelinating disorders. These disorders should receive priority while planning the allocation of resources, educational curriculum, training, and teaching programs.

Characterization of residue-specific glutathionylation of CSF proteins in multiple sclerosis - A MS-based approach.

Reduction of a disulfide linkage between cysteine residues in proteins, a standard step in the preanalytical preparation of samples in conventional proteomics approach, presents a challenge to characterize S-glutathionylation of proteins. S-glutathionylation of proteins has been reported in medical conditions associated with high oxidative stress. In the present study, we attempted to characterize glutathionylation of CSF proteins in patients with multiple sclerosis which is associated with high oxidative stress. Using the nano-LC/ESI-MS platform, we adopted a modified proteomics approach and a targeted database search to investigate glutathionylation at the residue level of CSF proteins. Compared to patients with Intracranial hypertension, the following CSF proteins: Extracellular Superoxide dismutase (ECSOD) at Cys195, α1-antitrypsin (A1AT) at Cys232, Phospholipid transfer protein (PLTP) at Cys318, Alpha-2-HS-glycoprotein at Cys340, Ectonucleotide pyrophosphate (ENPP-2) at Cys773, Gelsolin at Cys304, Interleukin-18 (IL-18) at Cys38 and Ig heavy chain V III region POM at Cys22 were found to be glutathionylated in patients with multiple sclerosis during a relapse. ECSOD, A1AT, and PLTP were observed to be glutathionylated at the functionally important cysteine residues. In conclusion, in the present study using a modified proteomics approach we have identified and characterized glutathionylation of CSF proteins in patients with multiple sclerosis.
