The effect of low dose thyroid replacement therapy in patients with episodic migraine and subclinical hypothyroidism: A randomised placebo-controlled trial.

INTRODUCTION: Migraine is a common headache syndrome associated with various other comorbidities. Thyroid replacement in migraine patients with hypothyroidism improves headaches; however, thyroid hormone replacement in subclinical hypothyroidism is debatable, and its efficacy is not known. OBJECTIVE AND METHODOLOGY: This prospective, single-centre, quasi-randomised interventional study was conducted on patients visiting the General Medicine and Neurology outpatient department at a tertiary centre to look at the efficacy of thyroxine in subclinical hypothyroidism. RESULTS: We assessed 87 patients for analysis; no patients were lost to follow-up. There was a decrease in all parameters evaluated (headache frequency, severity, duration, MIDAS score, MIDAS grade) at three months of follow-up in the treatment group compared to placebo group. There was a significant decrease in headache frequency and severity in the levothyroxine group compared to the placebo group at three months of follow-up. Also, the follow-up MIDAS score (mean ± SD: 6.30 ± 2.455 scores vs. 8.45 ± 5.757 scores) was significantly decreased by treatment at three months follow-up. CONCLUSION: Treatment of subclinical hypothyroidism effectively reduces migraine headaches, and it is logical to check thyroid function status in patients presenting with migraine headaches. However, a larger randomised controlled trial is required to prove the efficacy of levothyroxine in migraine with subclinical hypothyroidism.

Efficacy of Duloxetine in Patients with Central Post-stroke Pain: A Randomized Double Blind Placebo Controlled Trial.

OBJECTIVE: Central post-stroke pain (CPSP) refers to neuropathic pain in areas of the body corresponding to stroke lesions. Duloxetine, a serotonin-norepinephrine reuptake inhibitor, is safe and effective against neuropathic pain. In this randomized double-blind placebo-controlled study, we studied the effect of duloxetine in CPSP patients. METHODS: Consecutive patients satisfying the inclusion criteria were enrolled in the study and were randomized in a simple 1:1 randomization to duloxetine and placebo groups. Baseline demographic, clinical and imaging data were obtained. Prespecified primary outcome was comparison of change in pain intensity from baseline to 4 weeks, as assessed on Numeric Rating Scale (NRS) in both groups. Prespecified secondary outcomes were comparison of change in average pain severity from baseline to 4 weeks as measured on Short-form McGill Pain Questionnaire-2 (SFMPQ-2) score and Pain Disability Index (PDI) score and comparison of Patient Global Impression of Change (PGIC) score at the end of 4 weeks of treatment in both groups. Duloxetine at doses of 30 mg and similarly appearing placebo tablets were given and the dose was doubled if there was no response at the end of 2 weeks. Response to treatment was defined as ≥2 points reduction of NRS pain score. RESULTS: In total, 82 patients were enrolled in the study, 41 in each group. There was a significant difference in reduction in NRS score between duloxetine and placebo group from baseline (6.51 ± 1.03 vs 6.37 ± 1.41) to 4 weeks (3.02 ± 1.70 vs 4.40 ± 1.77, P = .02 for difference in reduction between groups). SFMPQ-2 score (P = .032) and Pain Disability Index score (P = .005) also differ significantly from baseline to 4 weeks between the two groups. PGIC score at the end of 4 weeks was significantly different between the two groups (5.15 ± 1.54 vs 3.89 ± 1.51; P < .001). Responder rate (defined as % of patients with ≥ 2 points reduction on NRS pain score from baseline to end of 4 weeks), on post hoc analysis was found to be significantly higher in duloxetine group (80.5%) than placebo group (43.9%) (P = .042). CONCLUSIONS: Duloxetine can be an effective treatment option for patients with moderate to severe central post-stroke pain.

Spectrum of neurological diseases across gangetic belt: a hospital based prospective observational study.

OBJECTIVE: Neurological disorders are the most common cause of morbidity and mortality in riverside cities. Earlier studies reported the presence of heavy metals in the riverside of Gangetic belt. Our study objective was to determine the prevalence of neurological diseases in Ganga riverside and further divided into sections as just across riverside within 25 kms and non-riverside as 25 kms away from the Ganga river. METHODS: This was a prospective observational study conducted in a tertiary care hospital of selected Gangetic belt. RESULTS: A total of 2016 patients were recorded in this period. Mean age of the participants was 47.89 years, majority were males 59.2%. Most of the patients n = 1154 were from within 25 kms of Ganga riverside and n = 862 patients were from non-riverside (25 kms away from Ganga river). Common neurological diseases were ischemic stroke 22.7%, haemorrhagic stroke 20.7%, seizures 13.7%, septic encephalopathy 9.4%, neuropathy 8.9%, Parkinson's disease 4.3%, myopathy 4.1%, myelitis 2.8%, headache 2.4%, amyotrophic lateral sclerosis 1.9% and functional disorder 1.9%. CONCLUSION: Present study showed that neurological diseases were more common in Ganga riverside and stroke including ischemic and hemorrhagic are most common neurological diseases noted in our study.

The pattern of primary headache in the North India population: a hospital-based study.

BACKGROUND: The aim of the study was to investigate the clinical profile, disease burden, quality of life, and treatment patterns of various headache subtypes. METHOD: In this prospective observational study, 815 patients presenting with chief complaints of headache between January 2020 to September 2021 were registered. After a detailed history, clinical examination, and subtyping, they were assessed at baseline with well-validated scales for severity (Visual Analogue Scale-VAS), disability burden (Migraine Disability Assessment- MIDAS), Humanistic burden (Headache Impact Test-HIT-6), and quality of life (World health organization-quality of life-WHO-QoL-8) scores. After initiating adequate management, parameters were reassessed at 3 and 6 months. RESULTS: 549 (67.7%) patients had migraine (395-episodic migraine, 144-chronic migraine), 266 (32.2%) patients had tension-type headache (TTH). Loss of sleep, prolonged working hours, and stress were common triggers. Disease burden, severity, and poor life quality was quite high in migraine patients (76.5% with moderate to severe disability, 61.7% with severe headache at onset, and 72% with poor life quality). All parameters had statistically significant improvement with preventive medication and lifestyle changes. CONCLUSION: In our study, we found migraine was the most common primary headache followed by TTH. Migraine patients had more severity, disease burdens, and inferior quality of life at onset compared to other headaches. With early and proper diagnosis as well as preventive treatment (including lifestyle modifications), all parameters could be reversed positively in a brief time. This is the first study on headache burden and its effect on the quality of life in the north Indian population.

Identification of Plasma Proteomic Biomarkers in Patients with Mild Cognitive Impairment.

Plasma proteomic profiling may provide novel biomarkers for the identification of mild cognitive impairment (MCI). The early diagnosis of MCI still remains a challenging task due to its diverse origin. Currently, molecular approaches have been used to identify MCI diversified origin as its onset is governed by a variety of molecular changes. Therefore, we aimed to find out molecular alteration in plasma using proteomics in patients with MCI for early detection of prodromal Alzheimer's disease (AD). To achieve this, we performed two-dimensional (2-D) gel electrophoresis coupled with MALDI-TOF/MS, which is used to analyze the differentially expressed proteins. In our study, we found three significantly altered proteins. Out of three differentially expressed proteins, one was downregulated and two were upregulated in MCI individuals as compared to control. Further, In silico analysis showed that identified proteins are involved in pathways such as complement and coagulation cascades, platelet activation and AD. STRING interaction network analysis revealed that the majority of proteins including apolipoprotein E (APO-E) have a common association with Transthyretin (TTR) and fibrinogen chain beta (FGB) protein. This suggests that APO-E, TTR and FGB are the key proteins with which other proteins interact to exert other biological functions. Conclusively, these proteins showing differential expression in the plasma might be used as a potent signature in blood for the diagnosis of MCI individuals.

"Oxygen Pheriwala:" An innovative model for SARS-CoV-2 screening in resource-limited settings.

The second wave of SARS-CoV-2 infection came as a hypoxic emergency and situation became worse in rural India, where undiagnosed COVID-19 patients died without any diagnosis or intervention. The primary aim of this innovative model was the early diagnosis of suspected SARS-CoV-2 cases, providing empirical treatment and timely referral to appropriate COVID care facilities. Fever was measured with infrared thermometer and oxygen saturation level with pulse oximeter. A total of 8203 people were screened, of which 274 persons were febrile and 69 (25%) were hypoxic too. Sixty-four out of 69 (93%) patients turned COVID-19 positive on reverse transcription-polymerase chain reaction. At the end of 3 weeks, 48/64 (75%) patients were successfully discharged. This model can be easily implemented in resource-limited regions to identify and prioritize the patients not only in this pandemic but also in outbreak of other communicable diseases.

Modes of Calcium Regulation in Ischemic Neuron.

Calcium (Ca2+) dysregulation is a major catalytic event. Ca2+ dysregulation leads to neuronal cell death and brain damage result in cerebral ischemia. Neurons are unable in maintaining calcium homeostasis. Ca2+ homeostasis imbalance results in increased calcium influx and impaired calcium extrusion across the plasma membrane. Ca2+ dysregulation is mediated by different cellular and biochemical mechanism, which leads to neuronal loss resulting stroke/cerebral ischemia. A better understanding of the Ca2+ dysregulation might help in the development of new treatments in order to reduce ischemic brain injury. An optimal concentration of Ca2+ does not lead to neurotoxicity in the ischemic neuron. Intracellular Ca2+ act as a trigger for acute neurotoxicity and this cause induction of long-lasting processes leading to necrotic and/or apoptotic post-ischemic delayed neuronal death or of compensatory, neuroprotective mechanisms has increased considerably. Moreover, routes of ischemic Ca2+ influx to neurons, involvement of intracellular Ca2+ stores and Ca2+ buffers, spatial and temporal relations between ischemia-induced increases in intracellular Ca2+ concentration and neurotoxicity will further increase our understanding about underlying mechanism and they can act as a target for the development of drugs. Here, in our article we are trying to provide a brief overview of various Ca2+ influx pathways involve in ischemic neuron and how ischemic neuron attempts to counterbalance this calcium overload.

Persistent facial pain in post-stroke patients, a hospital-based cohort study; experience from North India.

Background: Post-stroke pain is common after a stroke and might be underreported. We describe Persistent Facial Pain (PFP) developed in post-stroke patients. Method: ology: This was a prospective hospital-based cohort study of stroke patients, and patients were followed up. Out of 415 stroke patients, 26 developed PFP. Result: Out of all PFP patients, six patients had an ischemic stroke, and 20 had a hemorrhagic stroke. 57.7% of patients had hypertension, while 34.6 patients had diabetes. The stroke location was left-sided in 12 patients and right-sided in 14 patients. 46.15% of patients responded to venlafaxine, 30.77% responded to amitriptyline, and 23.08% responded to pregabalin. Conclusion: Persistent facial pain is a pain syndrome that might be missed in patients post-stroke. It might be more common in hemorrhagic stroke patients than in ischemic stroke patients. It responds adequately to antidepressants. A high index of suspicion is required to diagnose and appropriately manage these patients.

Clinico-radiological factors associated with aphasia outcome in post stroke patients: A prospective follow up study from eastern part of India.

BACKGROUND: Aphasia is a language disorder acquired secondary to brain damage. This study aims to evaluate clinical and radiological profile of patients with post stroke aphasia and factors affecting its recovery. METHODS: We conducted a prospective study of patients with first left Middle or Anterior Cerebral Artery infarct or Intracerebral Hemorrhage (ICH) with aphasia admitted within 14 days of stroke onset. Aphasia Quotient (AQ) was assessed at 2 weeks (AQ1) and 3 months (AQ2) using Western Aphasia Battery-Hindi version. Magnetic Resonance Imaging of brain with Diffusion Tensor Imaging (DTI) of bilateral Arcuate Fasciculus (AF) and Corticospinal Tract was done at admission, and stroke volume, Laterality Indices of Fractional Anisotropy (LI-FA), Mean Diffusivity (LI-MD), Radial Diffusivity (LI-RD), Axial Diffusivity (LI-AD) and Apparent Diffusion Coefficient (LI-ADC) were obtained. RESULTS: 36 patients [8 ICH and 28 Acute Ischemic Stroke (AIS)] were included. AQ1 and AQ2 were significantly higher in subcortical stroke than cortical. AQ2 and increase in AQ scores (including its subscores) were significantly higher in ICH than AIS. National Institutes of Health Stroke Scale score at admission and volume of stroke had significant negative correlation with AQ1 and AQ2. Laterality Index of Fractional Anisotropy of Arcuate Fasciculus [LI-FA (AF)] had significant positive correlation with AQ2 and naming score at 3 months. Laterality Index of Mean Diffusivity of Arcuate Fasciculus [LI-MD (AF)] had significant negative correlation with AQ1, AQ2 and all subcomponents of AQ2. Significant positive correlation was seen between improvements in Modified Rankin Scale score and AQ. CONCLUSION: The study shows that DTI can be used to predict severity of aphasia at follow up and recovery in language and motor functions occur in parallel.

One advantageous reflection of iron metabolism in context of normal physiology and pathological phases.

PURPOSE (BACKGROUND): The presented review is an updating of Iron metabolism in context of normal physiology and pathological phases. Iron is one of the vital elements in humans and associated into proteins as a component of heme (e.g. hemoglobin, myoglobin, cytochromes proteins, myeloperoxidase, nitric oxide synthetases), iron sulfur clusters (e.g. respiratory complexes I-III, coenzyme Q10, mitochondrial aconitase, DNA primase), or other functional groups (e.g. hypoxia inducible factor prolyl hydroxylases). All these entire iron-containing proteins ar e needed for vital cellular and organismal functions together with oxygen transport, mitochondrial respiration, intermediary and xenobiotic metabolism, nucleic acid replication and repair, host defense, and cell signaling. METHODS (METABOLIC STRATEGIES): Cells have developed metabolic strategies to import and employ iron safely. Regulatory process of iron uptake, storage, intracellular trafficking and utilization is vital for the maintenance of cellular iron homeostasis. Cellular iron utilization and intracellular iron trafficking pathways are not well established and very little knowledge about this. The predominant organs, which are associated in the metabolism of iron, are intestine, liver, bone marrow and spleen. Iron is conserved, recycled and stored. The reduced bioavailability of iron in humans has developed extremely efficient mechanisms for iron conservation. Prominently, the losses of iron cannot considerably enhance through physiologic mechanisms, even if iron intake and stores become excessive. Loss of iron is balanced or maintained from dietary sources. RESULTS (OUTCOMES): Numerous physiological abnormalities are associated with impaired iron metabolism. These abnormalities are appeared in the form of several diseases. There are duodenal ulcer, inflammatory bowel disease, sideroblastic anaemia, congenital dyserythropoietic anemias and low-grade myelodysplastic syndromes. Hereditary hemochromatosis and anaemia are two chronic diseases, which are responsible for disturbing the iron metabolism in various tissues, including the spleen and the intestine. Impairment in hepatic hepcidin synthesis is responsible for chronic liver disease, which is grounding from alcoholism or viral hepatitis. This condition directs to iron overload that can cause further hepatic damage. Iron has important role in several infectious diseases are tuberculosis, malaria trypanosomatid diseases and acquired immunodeficiency syndrome (AIDS). Iron is also associated with Systemic lupus erythematosus [SLE], cancer, Alzheimer's disease (AD) and post-traumatic epilepsy. CONCLUSION: Recently, numerous research studies are gradually more dedicated in the field of iron metabolism, but a number of burning questions are still waiting for answer. Cellular iron utilization and intracellular iron trafficking pathways are not well established and very little knowledge about this. Increased information of the physiology of iron homeostasis will support considerate of the pathology of iron disorders and also make available the support to advance treatment.

Effect of persistent organic pollutants in patients with ischemic stroke and all stroke: A systematic review and meta-analysis.

The role of environmental contaminants and their association with stroke is still being determined. Association has been shown with air pollution, noise, and water pollution; however, the results are inconsistent across studies. A systematic review and meta-analysis of the effect of persistent organic pollutants (POP) in ischemic stroke patients were conducted; a comprehensive literature search was carried out until 30th June 2021 from different databases. The quality of all the articles which met our inclusion criteria was assessed using Newcastle-Ottawa scaling; five eligible studies were included in our systematic review. The most studied POP in ischemic stroke was polychlorinated biphenyls (PCBs), and they have shown a trend for association with ischemic stroke. The study also revealed that living near a source of POPs contamination constitutes a risk of exposure and an increased risk of ischemic stroke. Although our study provides a strong positive association of POPs with ischemic stroke, more extensive studies must be conducted to prove the association.

Ecological and Health Risk Assessment of Heavy Metals Bioaccumulation in Ganges Fish Near Varanasi, India.

Heavy metal contamination in river Ganga is one of the factors for deterioration in its water quality and also adds to human health risks. We designed our study to achieve a holistic approach by not only estimating the concentration of heavy metals (lead, manganese, chromium, and cadmium) in the river water at different sites based on human anthropogenic activities but also in the fishes residing in the same sites that are collected for human consumption on daily basis. We found that Ganga River in Varanasi is highly loaded with metals (PLI = 6.698). Mean concentration in water was 1.29 mg/L for Pb, 1.325 mg/L for Mn, 0.169 mg/L for Cr, and 0.161 mg/L for Cd, which were above the permissible limits stated by Environment Protection Agency (EPA) in drinking water. Fish, including exotic and invasive species, were collected from the wild and were processed for the presence of these metals in their tissues. Degree of heavy metal concentration followed liver > gills > muscles. The highest accumulation of Pb was observed in Carpio (Cyprinus carpio) liver (8.86 µg/g) and lowest in Baikari (Clupisoma garua) muscles (0.07 µg/g). Total target hazard quotient (THQ) value, i.e., hazard index (HI) showed values in following sequence: Cyprinus carpio > Oreochromis niloticus > Channa gachua > Johnius coitor > Mastacembelus armatus > Mystus tengara > Clupisoma garua. Maximum HI value was recorded in C. carpio, which is highly consumed fish by humans, hence, may be harmful to them.

Evaluating the Effect of Pregabalin in the Treatment of Carpal Tunnel Syndrome: A Prospective, Randomized, Triple-Blinded, Placebo-controlled Trial.

OBJECTIVE: This study aimed to determine the effectiveness of pregabalin for the control of symptoms in mild to moderate idiopathic Carpal tunnel syndrome (CTS). METHODS: In this randomized, placebo-controlled trial, 146 mild to moderate idiopathic CTS patients were randomized into pregabalin (n=74) and placebo groups (n=72). Per protocol, analysis was conducted with 131 patients; pregabalin (n=65) and placebo (n=66). The drug titration dose was 50 mg once daily for the first week, twice daily for the second week and thrice daily for the next 6 weeks. The primary outcome included a change in the Symptom Severity Scale and Functional Status Scale (FSS) of the Boston Carpal Tunnel Questionnaire after the eighth week. The secondary outcome was the change in clinical and electrophysiological grading after 8 weeks of therapy. RESULTS: There was a statistically significant improvement in the mean Symptom Severity Scale (14.92±3.72 vs. 16.55±4.45; P =0.025) and FSS (10.77±2.64 vs. 12.0±2.55; P =0.007) in the pregabalin group after 8 weeks. Mean clinical and electrophysiological grading changed significantly from 2.3±0.7 to 2.1±0.8 ( P =0.001) and 1.9±0.7 to 1.8±0.8 ( P =0.020), respectively in the pregabalin group but not in the placebo group. DISCUSSION: The results of this study demonstrates that pregabalin is effective in ameliorating symptoms and improving functional outcomes in mild to moderate idiopathic CTS.

Thrombotic and Thromboembolic Complications After Vaccination Against COVID-19: A Systematic Review.

Thromboembolic complications after the COVID-19 vaccination have been reported from all over the world. We aimed to identify the thrombotic and thromboembolic complications that can arise after receiving various types of COVID-19 vaccines, their frequency, and distinguishing characteristics. Articles published in Medline/PubMed, Scopus, EMBASE, Google Scholar, EBSCO, Web of Science, the Cochrane Library, the CDC database, the WHO database, ClinicalTrials.gov, and servers like medRxiv.org and bioRxiv.org, as well as the websites of several reporting authorities between December 1, 2019, and July 29, 2021, were searched. Studies were included if they reported any thromboembolic complications post-COVID-19 vaccination and excluded editorials, systematic reviews, meta-analyses, narrative reviews, and commentaries. Two reviewers independently extracted the data and conducted the quality assessment. Thromboembolic events and associated hemorrhagic complications after various types of COVID-19 vaccines, their frequency, and distinguishing characteristics were assessed. The protocol was registered at PROSPERO (ID-CRD42021257862). There were 59 articles, enrolling 202 patients. We also studied data from two nationwide registries and surveillance. The mean age of presentation was 47 ± 15.5 (mean ± SD) years, and 71.1% of the reported cases were females. The majority of events were with the AstraZeneca vaccine and with the first dose. Of these, 74.8% were venous thromboembolic events, 12.7% were arterial thromboembolic events, and the rest were hemorrhagic complications. The most common reported event was cerebral venous sinus thrombosis (65.8%), followed by pulmonary embolism, splanchnic vein thrombosis, deep vein thrombosis, and ischemic and hemorrhagic stroke. The majority had thrombocytopenia, high D-dimer, and anti-PF4 antibodies. The case fatality rate was 26.5%. In our study, 26/59 of the papers were of fair quality. The data from two nationwide registries and surveillance revealed 6347 venous and arterial thromboembolic events post-COVID-19 vaccinations. COVID-19 vaccinations have been linked to thrombotic and thromboembolic complications. However, the benefits far outweigh the risks. Clinicians should be aware of these complications because they may be fatal and because prompt identification and treatment can prevent fatalities.

Generalized Morphea Coincident With Aplastic Anemia: A Case Report.

Morphea is a rare skin condition characterized by erythematous or violaceous lesions as well as sclerotic plaques. Patients with morphea frequently have other autoimmune disorders. Contributing factors are thought to be autoimmunity and an increase in extracellular matrix production. A case of a 45-year-old male patient with progressive restriction of both shoulder movements and patchy discoloration over the abdomen, neck, back, forearms, and bilateral axillae is discussed in this article. Examination revealed multiple shiny hyperpigmented to hypopigmented indurated plaques, and some lesions showed erythematous to violaceous borders, fine scales, and woody induration. The neurological examination was normal. Skin biopsy showed a sparse superficial perivascular lymphohistiocytic infiltrate with thickening of collagen bundles that were hyalinized in the reticular dermis, which was consistent with superficial morphea. Hematological tests showed pancytopenia and bone marrow aspiration revealed hypocellular marrow, which was consistent with aplastic anemia. The patient was diagnosed with generalized morphea with aplastic anemia. The patient was referred to a transplant center for further treatment, but, unfortunately, he died of sepsis while waiting for his transplant. Our case may indicate a possible link between aplastic anemia and generalized morphea. Due to a possible similar underlying mechanism of pathogenesis, treatment of aplastic anemia may be effective in morphea also. Aplastic anemia must be detected early to reduce complications and mortality in patients.

Pseudotumor Cerebri Syndrome (PTCS), Clinico-Radiological Profile: A Prospective Study.

Objectives: The aim of the study was to classify patients of Pseudotumor Cerebri Syndrome (PTCS) on the basis of newer classification along with its clinico-radiological correlations. Patients and Methods: A prospective study was conducted at a tertiary care teaching hospital. A total of 25 consecutive patients who fulfilled the new diagnostic criteria for PTCS were enrolled after taking informed written consent. A thorough clinical history, neurological examination and neuroimaging was carried out. Patients were classified into Primary and Secondary PTCS followed by Definite, Probable and Suggested as per new nomenclature. Results: Out of 25 patients, there were 9 patients in the primary PTCS group and 16 in the secondary PTCS group. Mean duration of symptoms was 40.84 ± 45.68 days. Primary PTCS group patients were significantly overweight and had higher BMI as compared to the secondary group with significant number of patients reporting recent rapid weight gain. The CSF pressure and protein were non-significantly higher in the primary PTCS group. We could classify 17 (68%) patients in our study as definite PTCS, 7 (28%) as probable PTCS and suggested PTCS in one patient. In secondary PTCS group there were 16 (64%) patients. APLA positivity was found to be the most common etiology for secondary PTCS with statistical significance (P = 0.025). Conclusions: Early recognition along with appropriate classification and prompt treatment can prevent vision loss in PTCS. Apart from obesity, recent weight gain is also closely related with primary PTCS.

A questionnaire-based survey of acceptability and satisfaction of virtual neurology clinic during COVID-19 lockdown: a preliminary study.

INTRODUCTION: Telemedicine during this pandemic acts as a lifeline for many non-COVID patients especially with chronic neurological diseases. The aim of present study was to evaluate cost effectiveness and level of satisfaction amongst patients from teleneurology outpatient department (OPD). METHODS: An online cross-sectional survey, having questions both in Hindi and English was conducted via telemedicine facility at Institute of Medical Sciences, Banaras Hindu University, Varanasi, India. Demographic variables, illness details, travel distance and time taken, travel expenditure, level of satisfaction and preferred choice among tele OPD versus in-person OPD once pandemic ends were recorded. RESULTS: Total 1388 patients filled the online COVID-19 teleneurology survey google form. Mean age was 39.21 ± 16.72 years. Majority (N = 824, 59%) were males. Six hundred (43%) patients' educational qualification were ≤ 10th standard. Majority of patients (N = 840, 60.5%) belonged to the rural background. Headache (N = 424, 30.5%) followed by backache (N = 220, 16%), stroke (N = 176, 13%) and seizure (N = 148, 11%) were the common illnesses. Travel time of > 5 hours was saved in 496 (36%) patients and travel expenditure of > Rs100 in 796 (57%) patients. About 96% (N = 1332) felt satisfied with the treatment advice via teleconsultation. DISCUSSION: Teleneurology facility is not only feasible but also affordable and acceptable in various neurological conditions. The chief reasons being no waiting time, saving of travelling time and travel expenditure with good satisfaction.

Caregiver Burden in Caregivers of Stroke Survivors: A Hospital-Based Study.

Background: A principal caregiver (CG) is directly affected by the patient's health problems leading to CG strain. In the present study, we evaluated the different factors related to increased CG burden in stroke survivors and assessed the relationship between patient's personal and clinical characteristics and CG's stress. Material and Methods: In this prospective, follow-up study, a total of 141 principle CGs of 164 First-ever stroke (FES) survivors were subjected to the Caregivers Strain Index (CSI) and Oberst Caregiving Burden Scale (OCBS) at 30 days (n = 141), 90 days (n = 129), and 6 months (n = 119) after informed consent. Patients were subjected to modified Rankin Scale (mRS) and Barthel index score assessment at the end of 30 days. Results: The mean age of CG was 49.8 ± 21.0 years, approximately 20 years lesser than that of the patients. 102 (72.34%) CGs were females. Urinary incontinence (p < 0.006) morbidity at 30 days, mRS (p = 0.004), and moderate to the severe neurological deficit on admission (p = 0.003) were the patient factors in FES cases leading to significant CGs stress. CG factors responsible for major stress were long caregiving hours (P < 0.001), anxiety (P < 0.001), disturbed night sleep (P < 0.001), financial stress (P < 0.001), younger age (P = 0.002), and CGs being daughters-in-law (P = 0.039). Conclusion: CG burden increases with increased severity of stroke. Integrated stroke rehabilitation services should also address CGs issues along with patients.

Systematic Review and Meta-analysis of Environmental Toxic Metal Contaminants and the Risk of Ischemic Stroke.

Background: Stroke is the second largest cause of mortality (WHO 2014) and long-lasting disability worldwide. Many risk factors are associated with stroke, such as age, gender, chronic illnesses, cardiovascular disease, lifestyle, and smoking. With global industrialization, the roles of environmental contaminants and their association with stroke are still unclear and have attracted much more attention. Materials and Methods: We conducted a systematic review on the environmental toxic metal contaminants and the risk of ischemic stroke. A comprehensive literature search was carried out till June 30, 2021 from databases such as PubMed, Science Direct, Embase, and Scopus. The quality of all the articles which met our inclusion criteria was assessed using Newcastle-Ottawa scaling, and four eligible studies were included for our systematic review. Results: The serum and urine cadmium concentrations were positively associated with the risk of ischemic stroke. There was an inverse association of serum and urine concentrations of mercury (Hg), serum concentration of gold and cerium with ischemic stroke, and the serum and urine concentrations of lead (Pb) had no association with ischemic stroke risk. Conclusion: The study showed strong associations between heavy metals and ischemic stroke, but more studies are required to prove the associations.
