Comparison of efficacy between beractant and poractant alfa in respiratory distress syndrome among preterm infants (28-33+6 weeks gestational age) using the less invasive surfactant administration (LISA) technique: A randomized controlled trial.

OBJECTIVE: Exogenous surfactant therapy is vital in managing respiratory distress syndrome (RDS) in preterm infants, with less invasive surfactant administration (LISA) gaining popularity. This study aimed to assess the efficacy and short-term outcomes of LISA using beractant and poractant alfa. STUDY DESIGN: In a randomized controlled trial, we enrolled preterm infants (28-33+6 weeks) with RDS requiring surfactant. LISA was employed, with beractant at 100 mg/kg or poractant-alfa at 200 mg/kg. Primary outcome was the need for intubation within 72 hours. RESULTS: Among 120 infants, 3.3% in both groups required intubation within 72 hours (p value 1.00, 95% CI 0.14-6.86). No significant differences in secondary outcomes were noted. However, beractant was significantly more economical than poractant-alfa, with a significantly lower surfactant cost and total care cost for infant hospital stays. CONCLUSION: Beractant and poractant-alfa exhibit similar efficacy in LISA for preterm infants with RDS. Economic considerations, especially in LMICs, favour beractant.

Autonomous closed-loop mechanistic investigation of molecular electrochemistry via automation.

Electrochemical research often requires stringent combinations of experimental parameters that are demanding to manually locate. Recent advances in automated instrumentation and machine-learning algorithms unlock the possibility for accelerated studies of electrochemical fundamentals via high-throughput, online decision-making. Here we report an autonomous electrochemical platform that implements an adaptive, closed-loop workflow for mechanistic investigation of molecular electrochemistry. As a proof-of-concept, this platform autonomously identifies and investigates an EC mechanism, an interfacial electron transfer (E step) followed by a solution reaction (C step), for cobalt tetraphenylporphyrin exposed to a library of organohalide electrophiles. The generally applicable workflow accurately discerns the EC mechanism's presence amid negative controls and outliers, adaptively designs desired experimental conditions, and quantitatively extracts kinetic information of the C step spanning over 7 orders of magnitude, from which mechanistic insights into oxidative addition pathways are gained. This work opens opportunities for autonomous mechanistic discoveries in self-driving electrochemistry laboratories without manual intervention.

The Efficacy and Safety of Sofosbuvir and Daclatasvir Treatment in Children and Adolescents With Thalassemia and Hepatitis C Virus Infection.

Background/Aim: Thalassemia patients are susceptible to hepatitis C virus (HCV) infection due to blood transfusions. Currently, data on treating HCV in thalassemic children with direct-acting antivirals is lacking. This study was performed to determine the efficacy and safety of sofosbuvir-daclatasvir combination therapy in thalassemic children and adolescents. Methods: A nonrandomized, open-label, interventional study was carried out in a tertiary care hospital. Consecutive noncirrhotic treatment-naïve thalassemic patients with HCV infection with viremia, within the age group of 6-18 years, were treated with the combination of sofosbuvir-daclatasvir: 200 mg + 30 mg for age 6-11 years (Group A) and 400 mg + 60 mg for age 12-18 years (Group B). The primary endpoint was sustained virological response at 12 weeks (SVR12). Results: A total of 70 patients (Group A 45, 64% male; Group B 25, 40% male) were recruited. The mean age was 8.5 years and 13.9 years in the two groups. Mean HCV Ribonucleic acid (RNA) levels in Groups A and B were 446906.1 IU/ml and 256187.8 IU/ml, respectively. SVR12 was achieved in 43 of 45 (95.5%) patients on an intention-to-treat basis and 43 of 44 (97.7%) patients on a perprotocol basis in Group A, and all patients in Group B (100%). In both groups, there was a significant improvement in biochemical parameters. Among the two patients who did not achieve SVR12 in Group A, one required termination of therapy due to urticaria. Conclusion: Sofosbuvir-daclatasvir based treatment in noncirrhotic, treatment-naive thalassemic children and adolescents infected with HCV is effective and safe.

An Observational Study on Response to Growth Hormone Therapy in Indian Patients of Short Stature with Special Emphasis on Biochemical Parameters and Bone Biomarkers.

Introduction: There is a lack of Indian data on short stature treatment using recombinant human growth hormone (rhGH). We explored the effects of such treatment in eastern Indian patients, with emphasis on biochemical parameters and bone biomarkers in addition to basic anthropometry. Methods: Our descriptive study covered 50 short stature patients of varied aetiology attending endocrine outpatient department (OPD) of a tertiary care teaching hospital. Patients were followed up for 1 year after the index visit, and prospective data were reconciled with past medical records. A dose of rhGH used was 0.18-0.375 mg/kg as standard, starting dose mostly being 0.2 mg/kg. Dosing was adjusted if the physician judged the clinical outcome to be less favourable than expected. Anthropometric parameters (height, weight, body mass index (BMI) and skeletal age) were recorded clinically, and various biochemical parameters and bone biomarkers were estimated from blood. Results: Among 50 subjects, 60% had idiopathic growth hormone (GH) deficiency and 26% had Turner's syndrome. The median age at treatment start was 10 years, and the median treatment duration was 25.5 months. The height increased more in the first year of therapy. In the last 6 months, the height velocity was approximately 0.5 cm/month. Although the weight increased significantly, the increment slowed down in the last 6 months. Both remained less than age- and gender-matched references throughout. The skeletal age was on average 2 years behind chronological age (CA)-being 8.7, 9.6 and 11.3 years, respectively, at therapy start, after one year and at study end. Fasting blood glucose (FBG), total cholesterol and calcium level changes were not statistically significant. Serum cortisol and phosphate showed a modest but statistically significant rise, while thyroid-stimulating hormone (TSH) level declined. Insulin-like growth factor 1 (IGF-1) increase was relatively pronounced. Among bone biomarkers, a decrease in CTx and an increase in vitamin D were significant. Dual-energy X-ray absorptiometry (DEXA) data indicated that bone mineral density was less than that of age-matched controls despite treatment. The therapy was well tolerated. Conclusions: rhGH treatment leads to significant improvement in anthropometry in Indian children comparable with Western data. Bone biomarker changes indicate decreased bone resorption and increased bone formation although bone mineral density still lags behind age-matched controls.

Satellite Epidemic of Covid-19 Associated Mucormycosis in India: A Multi-Site Observational Study.

BACKGROUND: Sudden upsurge in cases of COVID-19 Associated Mucormycosis (CAM) following the second wave of the COVID-19 pandemic was recorded in India. This study describes the clinical characteristics, management and outcomes of CAM cases, and factors associated with mortality. METHODS: Microbiologically confirmed CAM cases were enrolled from April 2021 to September 2021 from ten diverse geographical locations in India. Data were collected using a structured questionnaire and entered into a web portal designed specifically for this investigation. Bivariate analyses and logistic regression were conducted using R version 4.0.2. RESULTS: A total of 336 CAM patients were enrolled; the majority were male (n = 232, 69.1%), literate (n = 261, 77.7%), and employed (n = 224, 66.7%). The commonest presenting symptoms in our cohort of patients were oro-facial and ophthalmological in nature. The median (Interquartile Range; IQR) interval between COVID diagnosis and admission due to mucormycosis was 31 (18, 47) days, whereas the median duration of symptoms of CAM before hospitalization was 10 (5, 20) days. All CAM cases received antifungal treatment, and debridement (either surgical or endoscopic or both) was carried out in the majority of them (326, 97.02%). Twenty-three (6.9%) of the enrolled CAM cases expired. The odds of death in CAM patients increased with an increase in HbA1c level (aOR: 1.34, 95%CI: 1.05, 1.72) following adjustment for age, gender, education and employment status. CONCLUSION: A longer vigil of around 4-6 weeks post-COVID-19 diagnosis is suggested for earlier diagnosis of CAM. Better glycemic control may avert mortality in admitted CAM cases.

High-resolution vessel wall magnetic resonance imaging in intracranial vasculopathies: an experience from eastern India.

OBJECTIVE: To evaluate the role of high-resolution intracranial vessel wall imaging (HR-IVWI) in differentiation of various intracranial vasculopathies in addition to luminal and clinical imaging in the largest cohort of Indian stroke patients. METHODS: A single-center, cross-sectional study was undertaken recruiting consecutive stroke or TIA patients presenting within a month of onset, with luminal irregularity/narrowing upstream from the stroke territory. The patients were initially classified into TOAST and Chinese ischemic stroke sub-classification (CISS) on the basis of clinical and luminal characteristics and reclassified again following incorporation of HR-IVWI findings. RESULTS: In our cohort of 150 patients, additional use of HR-IVWI led to a 10.7 and 14% change in initial TOAST and CISS classification respectively (p < 0.001). In TOAST classification, 12 "undetermined aetiology" were reclassified into intracranial atherosclerotic disease (ICAD), 1 "undetermined aetiology" into CNS angiitis and 1 "undetermined aetiology" into arterial dissection. Similarly, in CISS 19 "undetermined aetiology" was reclassified into 16 large artery atherosclerosis (LAA) and 3 "other aetiology" consisting of one CNS angiitis, Moyamoya disease (MMD) and arterial dissection each. Two initial classification of MMD by CISS and TOAST were changed into ICAD. The observed change in diagnosis following incorporation of HR-IVWI was proportionately highest in ICAD (LAA) subgroup (TOAST-9.3%, CISS-12%). CONCLUSION: Adjunctive use of HR-IVWI, to clinical and luminal assessment, can significantly improve diagnostic accuracy during evaluation of intracranial vasculopathies, with its greatest utility in diagnosing in ICAD, CNS angiitis and dissection. ADVANCES IN KNOWLEDGE: HR-IVWI allows clearer etiological distinction of intracranial vasculopathies having therapeutic and prognostic implications.

Interrogating the Mechanistic Features of Ni(I)-Mediated Aryl Iodide Oxidative Addition Using Electroanalytical and Statistical Modeling Techniques.

While the oxidative addition of Ni(I) to aryl iodides has been commonly proposed in catalytic methods, an in-depth mechanistic understanding of this fundamental process is still lacking. Herein, we describe a detailed mechanistic study of the oxidative addition process using electroanalytical and statistical modeling techniques. Electroanalytical techniques allowed rapid measurement of the oxidative addition rates for a diverse set of aryl iodide substrates and four classes of catalytically relevant complexes (Ni(MeBPy), Ni(MePhen), Ni(Terpy), and Ni(BPP)). With >200 experimental rate measurements, we were able to identify essential electronic and steric factors impacting the rate of oxidative addition through multivariate linear regression models. This has led to a classification of oxidative addition mechanisms, either through a three-center concerted or halogen-atom abstraction pathway based on the ligand type. A global heat map of predicted oxidative addition rates was created and shown applicable to a better understanding of the reaction outcome in a case study of a Ni-catalyzed coupling reaction.

Evaluation of Mitral-Aortic Flow Velocity Integral Ratio as a Tool to Differentiate Between Severe and Nonsevere Mitral Regurgitation.

OBJECTIVES: To evaluate mitral-aortic flow velocity integral ratio (MAVIR) as an echocardiographic tool to differentiate between severe and nonsevere mitral regurgitation (MR), compared with regurgitant volume (RVol) and effective regurgitant orifice area (EROA), with subgroup analysis in patients with calcific mitral valve, both by transthoracic (TTE) and transesophageal (TEE) echocardiography. Also, whether MAVIR can be used as a screening tool for severe MR. DESIGN: Prospective, cross-sectional, observational. SETTING: Cardiac operating room of a tertiary-care hospital. PARTICIPANTS: One hundred adult patients with chronic mitral regurgitation with at least mild MR by two-dimensional Doppler and with absence of mitral stenosis, aortic valve disease, and rhythm other than sinus scheduled for cardiac surgery. The subgroup (n = 24) consisted specifically of patients with a calcific mitral valve. INTERVENTIONS: Preinduction TTE and postinduction TEE in the operating room. MEASUREMENTS AND RESULTS: MAVIR, RVol, and EROA were measured in all patients both by TTE and TEE. Cohen's kappa statistics was employed to quantify concordance among RVol, EROA, and MAVIR. Diagnostic indices of MAVIR toward diagnosis of severe MR also were quantified. The results showed a strong agreement, in differentiating severe from nonsevere MR, between MAVIR and both RVol and EROA in the whole cohort (n = 100) and the subgroup (n = 24), both by TTE and TEE. Diagnostic indices were high for MAVIR compared with RVol and EROA in detecting severe MR, both by TTE and TEE. CONCLUSION: MAVIR may be used as an echocardiographic tool to differentiate between severe and nonsevere MR, even in patients with calcific valves. It also can be used to screen patients for severe MR.

CHSI costing study-Challenges and solutions for cost data collection in private hospitals in India.

INTRODUCTION: Ayushman Bharat Pradhan Mantri Jan Aarogya Yojana (AB PM-JAY) has enabled the Government of India to become a strategic purchaser of health care services from private providers. To generate base cost evidence for evidence-based policymaking the Costing of Health Services in India (CHSI) study was commissioned in 2018 for the price setting of health benefit packages. This paper reports the findings of a process evaluation of the cost data collection in the private hospitals. METHODS: The process evaluation of health system costing in private hospitals was an exploratory survey with mixed methods (quantitative and qualitative). We used three approaches-an online survey using a semi-structured questionnaire, in-depth interviews, and a review of monitoring data. The process of data collection was assessed in terms of time taken for different aspects, resources used, level and nature of difficulty encountered, challenges and solutions. RESULTS: The mean time taken for data collection in a private hospital was 9.31 (± 1.0) person months including time for obtaining permissions, actual data collection and entry, and addressing queries for data completeness and quality. The longest time was taken to collect data on human resources (30%), while it took the least time for collecting information on building and space (5%). On a scale of 1 (lowest) to 10 (highest) difficulty levels, the data on human resources was the most difficult to collect. This included data on salaries (8), time allocation (5.5) and leaves (5). DISCUSSION: Cost data from private hospitals is crucial for mixed health systems. Developing formal mechanisms of cost accounting data and data sharing as pre-requisites for empanelment under a national insurance scheme can significantly ease the process of cost data collection.

A case control investigation of COVID-19 associated mucormycosis in India.

BACKGROUND: Increased occurrence of mucormycosis during the second wave of COVID-19 pandemic in early 2021 in India prompted us to undertake a multi-site case-control investigation. The objectives were to examine the monthly trend of COVID-19 Associated Mucormycosis (CAM) cases among in-patients and to identify factors associated with development of CAM. METHODS: Eleven study sites were involved across India; archived records since 1st January 2021 till 30th September 2021 were used for trend analysis. The cases and controls were enrolled during 15th June 2021 to 30th September 2021. Data were collected using a semi-structured questionnaire. Among 1211 enrolled participants, 336 were CAM cases and 875 were COVID-19 positive non-mucormycosis controls. RESULTS: CAM-case admissions reached their peak in May 2021 like a satellite epidemic after a month of in-patient admission peak recorded due to COVID-19. The odds of developing CAM increased with the history of working in a dusty environment (adjusted odds ratio; aOR 3.24, 95% CI 1.34, 7.82), diabetes mellitus (aOR: 31.83, 95% CI 13.96, 72.63), longer duration of hospital stay (aOR: 1.06, 95% CI 1.02, 1.11) and use of methylprednisolone (aOR: 2.71, 95% CI 1.37, 5.37) following adjustment for age, gender, occupation, education, type of houses used for living, requirement of ventilatory support and route of steroid administration. Higher proportion of CAM cases required supplemental oxygen compared to the controls; use of non-rebreather mask (NRBM) was associated as a protective factor against mucormycosis compared to face masks (aOR: 0.18, 95% CI 0.08, 0.41). Genomic sequencing of archived respiratory samples revealed similar occurrences of Delta and Delta derivates of SARS-CoV-2 infection in both cases and controls. CONCLUSIONS: Appropriate management of hyperglycemia, judicious use of steroids and use of NRBM during oxygen supplementation among COVID-19 patients have the potential to reduce the risk of occurrence of mucormycosis. Avoiding exposure to dusty environment would add to such prevention efforts.

An Observational Study showing Dipeptidyl Peptidase-4 (DPP-4) Activity and Gene Expression Variation in Chronic Liver Disease (CLD) Patients from a Tertiary Care Hospital of Eastern India.

Introduction: The studies in animal models of cirrhosis suggest that dipeptidyl peptidase type 4 (DPP-4) enzymes play a crucial role in disease pathogenesis. In this clinical observational study, activity of DPP-4 and related gene expression were analysed in chronic liver disease patients. Objectives: To understand the DPP-4 enzyme activity variation in the common types of chronic liver disease by assessing plasma and peripheral blood mononuclear cell (PBMC) DPP-4 activity and comparing with healthy controls and to explore DPP-4 gene expression in PBMC. Methods: We recruited 130 study subjects in four cohorts-46 nonalcoholic fatty liver disease (NAFLD), 23 non-alcoholic cirrhosis (NAC) excluding viral aetiology, 21 alcoholic liver disease (ALC), and 40 control subjects. Blood samples were analysed for relevant biochemical parameters and plasma DPP-4 activity. PBMC fraction was used for the DPP-4 activity assay and gene expression analysis. Results: We found that lower plasma DPP-4 activity among patient cohorts but this was not statistically significant. The PBMC DPP-4 activity was significantly lower in NAFLD cohort. In the same cohort, DPP-4 gene expression in PBMC fraction was significantly increased (P < 0.05). There was significant correlation between plasma DPP-4 activity and liver injury marker alanine aminotransferase (ALT) among NAFLD (rho = 0.459, P < 0.01), NAC (rho = 0.475, P < 0.05), and ALC (rho = -0.572, P < 0.01) patients. Plasma DPP-4 activity modestly predicted ALT plasma level (beta coefficient = 0.489, P < 0.01). Conclusions: The PBMC DPP-4 activity and DPP-4 gene expression gets significantly altered in NAFLD patients. Plasma DPP-4 activity also shows correlation with ALT levels in CLD patients. The role of DPP-4 in disease pathology in NAFLD and other forms of CLD needs to be explored.

Investigating Oxidative Addition Mechanisms of Allylic Electrophiles with Low-Valent Ni/Co Catalysts Using Electroanalytical and Data Science Techniques.

The catalysis by a π-allyl-Co/Ni complex has drawn significant attention recently due to its distinct reactivity in reductive Co/Ni-catalyzed allylation reactions. Despite significant success in reaction development, the critical oxidative addition mechanism to form the π-allyl-Co/Ni complex remains unclear. Herein, we present a study to investigate this process with four catalysis-relevant complexes: Co(MeBPy)Br2, Co(MePhen)Br2, Ni(MeBPy)Br2, and Ni(MePhen)Br2. Enabled by an electroanalytical platform, Co(I)/Ni(I) species were found responsible for the oxidative addition of allyl acetate. Kinetic features of different substrates were characterized through linear free-energy relationship (Hammett-type) studies, statistical modeling, and a DFT computational study. In this process, a coordination-ionization-type transition state was proposed, sharing a similar feature with Pd(0)-mediated oxidative addition in Tsuji-Trost reactions. Computational and ligand structural analysis studies support this mechanism, which should provide key information for next-generation catalyst development.

Comparison of Different Doses of Dexmedetomidine as Adjuvant for Infraumbilical Surgery in Patients Receiving Bupivacaine Spinal Anesthesia: A Randomized Controlled Trial.

BACKGROUND: Infraumbilical surgery today is done preferentially under subarachnoid block. The relatively short duration of analgesia is a limiting factor which is overcome by adding an adjuvant to intrathecal bupivacaine. We aimed to determine optimum dose of intrathecal dexmedetomidine as adjuvant to 0.5% hyperbaric bupivacaine in infraumbilical surgery. METHODS: A parallel group, double blind, randomized controlled trial was done with 105 adult patients posted for infraumbilical surgery under subarachnoid block. All subjects received 3.0 mL (15.0 mg) of 0.5% hyperbaric bupivacaine. Groups D5.0, D7.5, and D10.0 (n = 35 each) received additionally 5.0, 7.5, and 10.0 mcg intrathecal dexmedetomidine as adjuvant. The onset time of sensory block, its peak level and time to this level, maximum motor block and time to it, total duration of analgesia (time to first rescue), and vital parameters were recorded at intervals. Postoperative analgesia was assessed by visual analog scale score at 15 and 30 minutes, then every 30 minutes until 2 hours and then every hour until 6 hours. Treatment emergent adverse events (bradycardia, hypotension, and sedation) were documented. RESULTS: Maximum sensory level achieved was higher in Group D10.0 than in the other two groups. There was significant and dose-dependent shortening of the mean time to peak sensory block (3.9, 3.3, and 2.9 min; P ＜ 0.001) and peak motor block (5.6, 5.3, and 4.8 min; P ＜ 0.001), and prolongation of postoperative analgesia duration (206.9, 220.8, and 244.0 min; P ＜ 0.001) with escalating doses (5.0, 7.5, and 10.0 mcg, respectively) of dexmedetomidine. Hemodynamic effects and adverse events were comparable in the three groups. CONCLUSIONS: Intrathecal dexmedetomidine (10.0 mcg), as adjuvant to 0.5% hyperbaric bupivacaine (15.0 mg), facilitates rapid onset sensory and motor block and prolongs duration of postoperative analgesia in spinal anesthesia without significant adverse effects. Although absolute differences are modest, the results are better compared to 5.0 and 7.5 mcg doses.

Cost of Surgical Care at Public Sector District Hospitals in India: Implications for Universal Health Coverage and Publicly Financed Health Insurance Schemes.

BACKGROUND: In low- and middle-income countries (LMICs), provisioning for surgical care is a public health priority. Ayushman Bharat Pradhan Mantri-Jan Aarogya Yojana (AB PM-JAY) is India's largest national insurance scheme providing free surgical and medical care. In this paper, we present the costs of surgical health benefit packages (HBPs) for secondary care in public district hospitals. METHODS: The costs were estimated using mixed (top-down and bottom-up) micro-costing methods. In phase II of the Costing of Health Services in India (CHSI) study, data were collected from a sample of 27 district hospitals from nine states of India. The district hospitals were selected using stratified random sampling based on the district's composite development score. We estimated unit costs for individual services-outpatient (OP) visit, per bed-day in inpatient (IP) and intensive care unit (ICU) stays, and surgical procedures. Together, this was used to estimate the cost of 250 AB PM-JAY HBPs. RESULTS: At the current level of utilization, the mean cost per OP consultation varied from US$4.10 to US$2.60 among different surgical specialities. The mean unit cost per IP bed-day ranged from US$13.40 to US$35.60. For the ICU, the mean unit cost per bed-day was US$74. Further, the unit cost of HBPs varied from US$564 for bone tumour excision to US$49 for lid tear repair. CONCLUSIONS: Data on the cost of delivering surgical care at the level of district hospitals is of critical value for evidence-based policymaking, price-setting for surgical care and planning to strengthen the availability of high quality and cost-effective surgical care in district hospitals.

Knowledge, attitude, and practice survey on antimicrobial use and resistance among Indian clinicians: A multicentric, cross-sectional study.

Purpose: This multicentric questionnaire-based study was undertaken to address the lack of systematic background data on the knowledge, attitudes, and practices among Indian physicians related to antimicrobial use and resistance. Materials and Methods: A validated structured study questionnaire was used for capturing respondent particulars, antimicrobial prescribing habits, knowledge of antimicrobial resistance (AMR), ways of choosing and learning about antibiotics, agreement or disagreement with certain perceptions regarding antibiotics, selection of antibiotics in specific settings, and suggestions regarding rationalizing antimicrobial use in the practice setting. Summary statistical analysis of the pooled data was done. Results: Five hundred and six respondents with a mean (standard deviation) age of 31.4 (8.71) years participated in the study. Three hundred and twenty-seven were medical and 179 surgical discipline clinicians. Overall, the theoretical knowledge about antimicrobials was satisfactory, but areas of concern were noted in the attitude and practice domains. A substantial proportion of participants failed to identify the correct choice of antibiotics in the case-based scenarios. 38.33% reported not attending a single continuing medical education on antimicrobials during the past year. Statistically significant differences were not observed in the KAP quotient scores between medical and surgical discipline respondents. Conclusions: Despite satisfactory background knowledge regarding the rational use of antimicrobials and AMR patterns, there are discrepancies in the physicians' prescribing attitude and thus strengthen the case for instituting specific interventions to improve antimicrobial prescribing.

Acute onset movement disorders in diabetes mellitus: A clinical series of 59 patients.

BACKGROUND AND PURPOSE: No previous study has assessed the frequency and clinical-radiological characteristics of patients with diabetes mellitus (DM) and acute onset nonchoreic and nonballistic movements. We conducted a prospective study to investigate the spectrum of acute onset movement disorders in DM. METHODS: We recruited all the patients with acute onset movement disorders and hyperglycemia who attended the wards of three hospitals in West Bengal, India from August 2014 to July 2021. RESULTS: Among the 59 patients (mean age = 55.4 ± 14.3 years, 52.5% men) who were included, 41 (69.5%) had choreic or ballistic movements, and 18 (30.5%) had nonchoreic and nonballistic movements. Ballism was the most common movement disorder (n = 18, 30.5%), followed by pure chorea (n = 15, 25.4%), choreoathetosis (n = 8, 13.6%), tremor (n = 5, 8.5%), hemifacial spasm (n = 3, 5.1%), parkinsonism (n = 3, 5.1%), myoclonus (n = 3, 5.1%), dystonia (n = 2, 3.4%), and restless leg syndrome (n = 2, 3.4%). The mean duration of DM was 9.8 ± 11.4 years (89.8% of the patients had type 2 DM). Nonketotic hyperglycemia was frequently (76.3%) detected. The majority (55.9%) had no magnetic resonance imaging (MRI) changes; the remaining showed striatal hyperintensity. Eight patients with MRI changes exhibited discordance with sidedness of movements. Most of the patients (76.3%) recovered completely. CONCLUSIONS: This is the largest clinical series depicting the clinical-radiological spectrum of acute onset movement disorders in DM. Of note was that almost one third of patients had nonchoreic and nonballistic movements. Our findings highlight the importance of a capillary blood glucose measurement in patients with acute or subacute onset movement disorders, irrespective of their past glycemic status.

Epidemiology of Moyamoya Angiopathy in Eastern India.

Introduction: Moyamoya angiopathy (MMA) is a chronic, progressive intracranial vasculopathy with variation in prevalence and clinical manifestations across different populations. This study was aimed to estimate the frequency of MMA as an etiology of stroke and its epidemiological features in the largest cohort of MMA patients in India. Method: A single-centered cross-sectional observational study over a period of 5 years (2016-2021) was undertaken among consecutive stroke and transient ischemic attack (TIA) patients to look for the presence of MMA angiographically. Each patient with angiographically proven MMA was further evaluated for demographic, clinical, and radiological characteristics. Results: Among 10,250 consecutive stroke and TIA patients (ischemic = 78%, hemorrhagic = 22%), frequency of MMA was 1.56% (n = 160); 15.3% among children. Female preponderance (Male:Female = 1:1.4) was noted among 160 MMA patients, with bimodal age distribution, first peak at 3-8 years, and a shorter second peak at 41-47 years. Childhood-onset MMA was seen in 75 (46.9%) with commonest initial neurological symptom of fixed-motor-weakness (44.0%), followed by TIA (26.7%); while 85 (53.1%) had adult-onset MMA with fixed-motor-weakness (50.6%) followed by headache (24.7%) as the predominant initial neurological symptom; seizure significantly higher in children (p < 0.001) and headache in adults (p = 0.012). Transient and fixed neurological manifestations constituted 87.5 and 69.4% respectively, of symptoms throughout the disease course. Cerebral infarction (45.0%) and TIA (21.9%) were the commonest types of MMA. On brain imaging, infarction was noted in 80.6%, hemorrhage in 11.3%, significantly higher among adults (p < 0.001). Cortical infarct and Gyral pattern were commoner in children (p = 0.004), subcortical infarcts in adults (p = 0.018). Frequent Suzuki staging observed was stage 4 (31.3%), followed by stage 3 (30.0%). Involvement of posterior circulation was detected in 55.6%, brain atrophy at the time of diagnosis was seen in 65.0%. Conclusion: MMA is an important etiological consideration in patients with stroke, especially in children. It can present with a myriad of transient neurological symptoms, frequently overlooked, leading to delayed diagnosis, and contributing to socio-economic burden. Indian MMA showed aberrations in its gender predisposition, age distribution, frequency of familial cases, disease manifestation, and type of stroke, in comparison to its Japanese and Caucasian counterparts pointing to the inter- and intra-continent differences of MMA phenotype. Future development of the Indian MMA national registry is of essence.

Premedication with Fentanyl for Less Invasive Surfactant Application (LISA): A Randomized Controlled Trial.

INTRODUCTION: Currently, there is no consensus regarding analgesic premedication before the surfactant administration by less invasive surfactant application (LISA) procedure. In this randomized controlled trial, we compared the level of comfort of preterm infants receiving fentanyl as analgesic and sedative versus no fentanyl during LISA procedure. METHODS: We randomized 34 preterm infants of 28+0-33+6 weeks of gestation with respiratory distress syndrome (RDS) within 6 h of birth to receive either fentanyl (1 µg/kg intravenous) or no premedication during surfactant administration by LISA procedure. Primary objective was to assess the proportion of preterm infants to be comfortable during the procedure [revised premature infant pain profile (R-PIPP) score ≤12] and secondarily complications occurring during the procedure, hemodynamically significant patent ductus arteriosus (hsPDA), intraventricular hemorrhage (IVH) (≥ grade 3), bronchopulmonary dysplasia (BPD) and composite outcome of BPD/mortality. RESULTS: Proportion of preterm infants with a R-PIPP score ≤12 during LISA was significantly higher in the fentanyl group [15/17 (88.23%) vs. 8/17 (47.05%); p value 0.025]. There were no differences in secondary outcome parameters. CONCLUSION: Low-dose fentanyl during LISA procedure resulted in more comfort in preterm infants and without increased complication of both the LISA procedure and fentanyl administration. Further studies are needed to determine the safest and most effective pharmacologic measures to prevent pain and discomfort during LISA.

Respiratory distress syndrome (RDS) in neonates is associated with prematurity, and surfactant administration is essential for its management. Surfactant instillation through a thin intratracheal catheter in spontaneously breathing infants with nasal continuous positive airway pressure (nCPAP) is known as less invasive surfactant application (LISA). Till date, there is no consensus regarding analgesic premedication before the surfactant administration by LISA procedure. In this randomized controlled trial, we compared the level of comfort of preterm infants receiving fentanyl as analgesic and sedative versus no fentanyl during LISA procedure. We reported that proportion of preterm infants with severe pain during LISA was significantly lower in the fentanyl group. There were no differences in clinical outcome parameters. So, we concluded that low-dose fentanyl during LISA procedure resulted in more comfort in preterm infants and without increased complication of both the LISA procedure and fentanyl administration.
