Saurabh Kumar,Swarndeep Singh,Nand Kumar,Rohit Verma 대한정신약물학회 2018 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.16 No.1

Objective: The literature on managing migraine non-responsive to pharmacological approaches and that co-occurring with depression is scanty. The comorbid condition predicts a poorer prognosis for migraine as well as depression. The present report assesses efficacy and tolerability of high frequency repetitive transcranial magnetic stimulation (rTMS) over left dorsolateral prefrontal cortex as a treatment modality for migraine with comorbid depression. Methods: The current retrospective chart review assesses effectiveness of high frequency rTMS over left dorsolateral prefrontal cortex as a treatment modality to manage migraine occurring comorbid with depression in 14 subjects. Results: The mean scores on Migraine Disability Assessment Test (MIDAS) and depression rating scale reduced significantly from 21.14±3.01 and 20.71±3.95 at baseline to 13.93±6.09 and 14.21±5.52 respectively, after rTMS. There was significant improvement in migraine frequency, severity and functional disability assessed using MIDAS scores (p <0.05) following high frequency rTMS compared to baseline. Conclusion: There is a role of applying rTMS as a potential therapeutic modality in the integrated management of a distinct subgroup of migraine patients with comorbid depression.

Saurabh Singh,Jyoti Prakash,Rakesh Singh,Ashish Verma,Hemant Bansal 대한척추외과학회 2016 Asian Spine Journal Vol.10 No.5

Study Design: Prospective study. Purpose: To establish the significance of cerebrospinal fluid (CSF) nitric oxide metabolite (NOx) concentration in acute spinal cord injury (SCI) patients to assess the neurological severity and prognosis. Overview of Literature: Quantitative analysis of specific biomarkers in CSF will assess neurological severity more accurately and permit the formulation of a more precise management plan. Methods: Forty SCI patients represented the cases and 20 lower limb injury patients were the controls. NOx concentration in CSF was measured at week 1, 2, and 4 by Griess method. Magnetic resonance imaging (MRI, T2-weighted) done in each case to measure cord edema and neurological severity was assessed using the Frankel classification. Results: CSF NOx concentration peaked at week 2 and declined to normal by week 4. The concentration remained normal in controls. Mean NOx concentration was directly proportional to the severity of acute SCI as correlated with cord edema seen in MRI and neurological severity assessed. Conclusions: CSF NOx concentration can be considered a specific quantitative biomarker in acute stage of SCI to predict the severity and prognosis of SCI patients.

Yadav, Saurabh,Verma, Vandana,Abhinav, Abhinav Cellmed Orthocellular Medicine and Pharmaceutical 2019 셀메드 (CellMed) Vol.9 No.3

Now researchers have focused attention on exploring the mechanism of acute responses of heat stress given in heat therapy that ultimately promotes the long term health benefits. Heat therapy is not a new idea rather it was practiced since thousands years back in the form of hot bath, sauna bath, steam room. Similarly in Ayurveda there is very comprehensive description of heat therapy in the form of Svedan karma (Sudation therapy). Svedan is a process to induce sweating artificially in a patient who had already undergone Snehan. Svedan is applied for purification of body, as well as in management of various disorders originated due to vitiation of Vata, Kapha Dosha, Meda Dhatu and musculoskeletal disorders. It produces various beneficial effects by augmenting the Agni like clears the channels, liquefies the deposited Dosha, regulates Vata Dosha, helps in removal and pacification of Dosha, augments metabolism (Agni Deepan), increases appetite, flexibility in body parts, softness and shining of skin, removes coldness, stiffness, drowsiness, improves joint motility. However, Svedana karma is vastly used by Ayurveda Physicians in treatment of various disorders but the mechanisms of beneficial effects produced by Svedan Karma are yet not completely explored on scientific basis. In this article, we will discuss and try to establish a possible mechanism of action of Svedana karma in relation to heat stress, mitochondrial adaptation, heat shock protein (HSP) and glucocorticoids as these are secreted under stressful conditions.

Background Aplastic anemia (AA), an unusual hematological disease, is characterized by hypoplasia of the bone marrow and failure to form blood cells of all three lineages resulting in pancytopenia. This study aimed to investigate TNF--308 and IFN--874 gene polymorphisms and their respective plasma protein levels in patients with AA and healthy controls. Methods Two hundred and forty individuals were included in this study; the case group comprised 120 AA patients, while 120 healthy individuals served as controls. Genotyping was performed using the PCR-restriction length fragment polymorphism method and TNF--308 and IFN--874 plasma levels were evaluated using an ELISA kit. Results There was a significantly higher prevalence of the IFN--874 genotype in patients with AA than in healthy controls, while the TNF--308 genotype was associated with lower risk of developing AA. Furthermore, the levels of both TNF--308 and IFN--874 were higher in the plasma of AA patients. Conclusion Our findings suggest that the IFN--874 genotype may be a greater risk factor in the causation of AA, whereas the TNF--308 genotype has a protective role in the North Indian population.

New Onset Obsessive Compulsive Disorder Following High Frequency Repetitive Transcranial Magnetic Stimulation over Left Dorsolateral Prefrontal Cortex for Treatment of Negative Symptoms in a Patient with Schizophrenia

Harshit Garg,Saurabh Kumar,Swarndeep Singh,Nand Kumar,Rohit Verma 대한정신약물학회 2019 CLINICAL PSYCHOPHARMACOLOGY AND NEUROSCIENCE Vol.17 No.3

Obsessive-compulsive symptoms and/or obsessive-compulsive disorders (OCD) are frequently comorbid with schizophrenia, though the exact clinical and etiological relationship between them is poorly understood. Here we describe a case that, to the best of our knowledge, is the first report of new-onset OCD in a patient who was receiving high-frequency repetitive transcranial magnetic stimulation over left dorsolateral pre-frontal cortex as an adjuvant therapy for negative symptoms of schizophrenia. Thisreport supports our understanding of OCD as a brain disorder involving hyperactivity of pre-frontal cortex and cortico-striatal-thalamo-cortical circuit dysfunction.

DOES SOCIAL MEDIA PROMOTES NON-DECEPTIVE COUNTERFEITING? EMPIRICAL EVIDENCES FROM INDIA

Ritu Raj,Saurabh Verma,Sunil Kumar Yadav 글로벌지식마케팅경영학회 2023 Global Marketing Conference Vol.2023 No.07

Social media has become popular in both business and research as many studies have explored the impact of this medium on the purchase behavior of consumers but surprisingly not in the domain of counterfeiting. Social media has become a significant part of today's lifestyle and it has created new channels for brand manufacturers and consumers to communicate. The present study tries to assess the impact of social media determinants on counterfeit purchase intention. The study explored three factors of social media namely social media platform, user-generated content, and social media word of mouth. Further, the study checks for the mediation effect of consumer attitude between social media determinants and purchase intention. The data for the present study were collected from three metropolitan cities of India namely Delhi, Kolkata, and Mumbai. The PLS-SEM was used on 406 respondents for further analysis and validation. The results revealed that there is a significant relationship between social media platforms, user-generated content, and purchase intention. However, an insignificant relationship was found between social media word of mouth and purchase intention. Further, the study suggested that attitude mediates the relationship between social media determinants and the purchase intention of consumers towards the purchase of counterfeit products in India.

Karan Sachdeva,Peeyush Kumar,Bhaskar Kante,Sudheer K. Vuyyuru,Srikant Mohta,Mukesh K. Ranjan,Mukesh K. Singh,Mahak Verma,Govind Makharia,Saurabh Kedia,Vineet Ahuja 대한장연구학회 2023 Intestinal Research Vol.21 No.2

Background/Aims: Intestinal tuberculosis (ITB) and Crohn’s disease (CD) frequently present with a diagnostic dilemma because of similar presentation. Interferon-gamma release assay (IGRA) has been used in differentiating ITB from CD, but with sparse reports on its diagnostic accuracy in tuberculosis endemic regions and this study evaluated the same. Methods: Patients with definitive diagnosis of ITB (n=59) or CD (n=49) who underwent IGRA testing (n=307) were retrospectively included at All India Institute of Medical Sciences, New Delhi (July 2014 to September 2021). CD or ITB was diagnosed as per standard criteria. IGRA was considered positive at >0.35 IU/mL. Relevant data was collected and IGRA results were compared between ITB and CD to determine its accuracy. Results: Among 59 ITB patients (mean age, 32.6±13.1 years; median disease duration, 1 year; male, 59.3%), 24 were positive and 35 tested negative for IGRA. Among 49 CD patients (mean age, 37.8±14.0; median disease duration, 4 years; male, 61.2%), 12 were positive and 37 tested negative for IGRA. Hence, for diagnosing ITB, IGRA showed a sensitivity, specificity, positive and negative predictive values of 40.68%, 75.51%, 66.67%, and 51.39%, respectively. The area under the curve of IGRA for ITB diagnosis was 0.66 (95% confidence interval, 0.55–0.75). In a subset (n=64), tuberculin skin test (TST) showed sensitivity, specificity, positive and negative predictive values of 64.7%, 73.3%, 73.3%, and 64.71%, respectively. IGRA and TST were concordant in 38 (59.4%) patients with κ=0.17. Conclusions: In a tuberculosis endemic region, IGRA had poor diagnostic accuracy for differentiating ITB from CD, suggesting a limited value of IGRA in this setting.
