The Global ECT-MRI Research Collaboration (GEMRIC): Establishing a multi-site investigation of the neural mechanisms underlying response to electroconvulsive therapy.
Major depression, currently the world's primary cause of disability, leads to profound personal suffering and increased risk of suicide. Unfortunately, the success of antidepressant treatment varies amongst individuals and can take weeks to months in those who respond. Electroconvulsive therapy (ECT), generally prescribed for the most severely depressed and when standard treatments fail, produces a more rapid response and remains the most effective intervention for severe depression. Exploring the neurobiological effects of ECT is thus an ideal approach to better understand the mechanisms of successful therapeutic response. Though several recent neuroimaging studies show structural and functional changes associated with ECT, not all brain changes associate with clinical outcome. Larger studies that can address individual differences in clinical and treatment parameters may better target biological factors relating to or predictive of ECT-related therapeutic response. We have thus formed the Global ECT-MRI Research Collaboration (GEMRIC) that aims to combine longitudinal neuroimaging as well as clinical, behavioral and other physiological data across multiple independent sites. Here, we summarize the ECT sample characteristics from currently participating sites, and the common data-repository and standardized image analysis pipeline developed for this initiative. This includes data harmonization across sites and MRI platforms, and a method for obtaining unbiased estimates of structural change based on longitudinal measurements with serial MRI scans. The optimized analysis pipeline, together with the large and heterogeneous combined GEMRIC dataset, will provide new opportunities to elucidate the mechanisms of ECT response and the factors mediating and predictive of clinical outcomes, which may ultimately lead to more effective personalized treatment approaches
A comparison of three media for isolation of Nocardia species from clinical specimens.
The study was carried out to compare the efficacy of three media namely Modified Thayer Martin medium, McClung′s carbon free broth with paraffin bait and paraffin agar in isolating Nocardia species from clinical specimens. Two hundred and seventy six clinical specimens from 245 cases were studied which included cases of bronchopulmonary and systemic infections and cases of mycetoma. Paraffin agar was found to be an inexpensive and selective medium for isolation of Nocardia species when compared with Modified Thayer Martin medium and paraffin bait techniques
A rare case of Histoplasma fungemia in an AIDS patient
Disseminated cases of histoplasmosis in acquired immune deficiency
syndrome (AIDS) are rarely reported from India. Most of these cases
report isolation of this fungus from the bone marrow, lymph node
aspirate, spleenic aspirate, and biopsies. We report isolation of
Histoplasma capsulatum from the blood of an AIDS patient. A 30-year-old
male from Utter Pradesh was admitted with fever, loss of appetite, and
nausea since two months. Few intracellular and extracellular budding
cells were observed on bone marrow examination on the fifth day of
admission. Diagnosis was confirmed by blood cultures taken on the 11th
day of admission. Amphotericin B was started, but the patient′s
condition deteriorated and he died
Case Report - Epidural mass due to Aspergillus flavus causing spinal cord compression - A case report and brief update
Aspergillus infection of the central nervous system (CNS) is
an uncommon disease. Most of the reported cases are of sinocranial
spread and cases with contiguous spread to spinal cord from lung and
other organs are uncommon. A case of pulmonary aspergillosis with
extension to thoracic vertebrae forming a paraspinal mass resulting in
neurological deficit due to Aspergillus flavus , is reported.
The 43 year old patient did not have any obvious predisposing
condition. He presented with loss of motor function and succumbed to
the infection despite operative intervention and antifungal therapy. A
brief update on CNS aspergillosis is presented along with detailed
clinical, radiological and laboratory work up of the patient
