Ophthalmologic manifestations since the initial presentation associated with persistent myeloid the leukemia disease: An assessment.
Panel count data describes aggregated counts of recurrent events observed at discrete time points. To understand dynamics of health behaviors and predict future negative events, the field of quantitative behavioral research has evolved to increasingly rely upon panel count data collected via multiple self reports, for example, about frequencies of smoking using in-the-moment surveys on mobile devices. However, missing reports are common and present a major barrier to downstream statistical learning. As a first step, under a missing completely at random assumption (MCAR), we propose a simple yet widely applicable functional EM algorithm to estimate the counting process mean function, which is of central interest to behavioral scientists. The proposed approach wraps several popular panel count inference methods, seamlessly deals with incomplete counts and is robust to misspecification of the Poisson process assumption. Theoretical analysis of the proposed algorithm provides finite-sample guarantees by expanding parametric EM theory [3, 34] to the general non-parametric setting. We illustrate the utility of the proposed algorithm through numerical experiments and an analysis of smoking cessation data. We also discuss useful extensions to address deviations from the MCAR assumption and covariate effects.Background  Prehospital care is nonexistent in most rural and semiurban areas. The implementation of golden hour care is still unachieved. The psychosocial problems of family members who accompany the traumatic brain injury (TBI) survivors after road traffic accidents (RTA) are not given attention during prehospital care. Therefore, the current study was aimed to understand the prehospital psychosocial impact on family members. Methodology  A cross-sectional study was conducted at the Emergency and Trauma Care Centre at National Institute of Mental Health and Neurosciences (NIMHANS), Bengaluru between July 2017 to April 2018. Forty-five ( n = 45) referred family members providing care for trauma survivors were purposively recruited in the study. Structured checklists were administered to measure the psychological reactions and psychosocial problems experienced by the family members during prehospital care. Data analysis was analyzed using the R software 3.0.1 version. Results  TBI survivor's mean age was found to be 33 years (33.09 ± 13.20), of which males were 23 (51.1%) and females were 22 (48.9%), respectively. The result depicted first aid was provided by unskilled people after an average of 41 minutes (41 ± 30). The results further showed that family members had experienced agitation (100%), shock (82.2%), fatigue and headache (75.6%), depression (66.7%), feeling of hopelessness (55.6%) helplessness, and lack of support from family and financial constraints (48.9%) during prehospital care. Conclusion  Psychosocial interventions need to be provided during prehospital care by trained medical and psychiatric social work professionals to address the need of family members during the crisis.Context  Due to the wide spectrum of clinical illness in coronavirus disease 2019 (COVID-19) patients, it is important to stratify patients into severe and nonsevere categories. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been evaluated rapidly by a few studies worldwide for its association with severe disease, but practically none have been conducted in the Indian population. This study was undertaken to examine the role of NLR and PLR in predicting severe disease in Indian patients. Objectives  The objective was to study the association of NLR and PLR observed at the time of admission with maximum disease severity during hospitalization and to study their role in predicting disease severity. Material and Methods  A total of 229 COVID-19 patients were admitted at the center during the study period. After applying inclusion and exclusion criteria, 191 patients were included in the study. The demographic, clinical, and laboratory (complete blood count, NLR, and PLR) data ofand PLR, both showing acceptable AUCs, can be used as screening tools to predict disease severity. However, NLR was a better predictor of disease severity.Objectives  Stringent quality control is an essential requisite of diagnostic laboratories to deliver consistent results. Measures used to assess the performance of a clinical chemistry laboratory are internal quality control and external quality assurance scheme (EQAS). However, the number of errors cannot be measured by the above but can be quantified by sigma metrics. The sigma scale varies from 0 to 6 with "6" being the ideal goal, which is calculated by using total allowable error (TEa), bias, and precision. However, there is no proper consensus for setting a TEa goal, and influence of this limiting factor during routine laboratory practice and sigma calculation has not been adequately determined. The study evaluates the impact of the choice of TEa value on sigma score derivation and also describes a detailed structured approach (followed by the study laboratory) to determine the potential causes of errors causing poor sigma score. Materials and Methods  The study was conducted at a clinical biochemistryn the TEa values selected, and using the same bias and precision values in the sigma equation. The laboratories should thereby choose appropriate TEa goals and make judicious use of sigma metric as a quality improvement tool.Background  Gall bladder carcinoma (GBC) is the most common malignancy of the biliary tract. click here Being known for its geographical and racial variations, and compared with the global statistics, its incidence is higher in the Indian subcontinent, mainly in the northern and eastern regions, accounting for 80 to 95% of cases. Aims and Objectives  This study was conducted to evaluate the clinic-pathological spectrum and expression of EGFR and HER-2/NEU in GBCs and to understand their relation to prognosis, paving the way for targeted therapies for better treatment outcomes and patient survival. Materials and Methods  This is a prospective study performed in a tertiary care hospital in 30 resected specimens of GBC cases recorded in our Department of Pathology from November 2017 to November 2019. Clinical history including the radiological reports and demographic parameters were included in the study pro forma. Immunohistochemical (IHC) staining for EGFR and HER-2/NEU was performed on all the selected cases. Clinicopate in poorly differentiated carcinomas as compared to the well-differentiated carcinomas, whereas HER-2/NEU expression is more in well-differentiated carcinomas. Therefore, they may serve as independent prognostic factors and also as targets for molecular therapy in GBCs.Being a planar structure, fetal diagnosis of aorto-pulmonary window poses great challenge. A few echocardiographic signs can help to clinch the diagnosis.We report a case of 8-year-old boy with unexplained desaturation and clubbing. Echocardiography showed anomalous drainage of right superior vena cava into left atrium. He did not have any neurological symptoms preoperatively. Some perioperative observations and subtle postoperative behavioral changes prompted us to investigate him further. He was found to have extensive cerebral arteriovenous malformations and hemiatrophy of brain.Transcatheter closure of patent ductus arteriosus is the standard of care. Retrieval of a duct occluder device is generally easy until it is detached from the delivery cable. We report two instances of failed retrieval of the device due to sheath tip invagination. The report highlights the importance of prompt identification of the mechanism of unforeseen complications in managing them effectively.We report a rare association of common arterial trunk with left pulmonary artery sling and highlight the importance of cross-sectional imaging in complex congenital cardiac lesions. The patient was antenatally diagnosed with common arterial trunk and underwent surgical repair in the neonatal period. At the age of 20 months, the patient presented with respiratory symptoms and increased right ventricular pressure. Multislice computed tomography demonstrated a pulmonary sling with compression of the distal trachea. Surgical correction of the pulmonary sling and change of the right ventricular to pulmonary artery conduit to a bigger size was performed.Transposition of the great arteries with total anomalous pulmonary venous connection is a rare anomaly with varied management approach depending on the time of presentation; the management of cases which present early is usually by anatomical surgical approach while late presentation is by physiologic approach. This is due to early left ventricular mass regression as a result of the absence of volume and pressure load to the left ventricle (LV). We report a late presentation (at 1½ years of age) that had a successful anatomic surgical correction because the LV was "prepared" by both pressure and volume load from pulmonary arterial hypertension and large ostium secundum atrial septal defect.In the case of prolonged, undiagnosed persistent junctional reciprocating tachycardia in infants, compensatory mechanisms are exhausted leading to heart failure. However, when cardioverted to sinus rhythm patients often deteriorate due to cardiac output dependency on the higher rates. Extracorporeal membrane oxygenation (ECMO) is often used to stabilize their hemodynamic status. A 7-month-old female infant was admitted in cardiogenic shock due to drug refractory supraventricular tachycardia (SVT). Pharmacological cardioversion to sinus rhythm with heart rate (HR) of 90 bpm was achieved but resulted in hemodynamic deterioration and early recurrence of arrhythmia. Right atrial overdrive pacing (ODP) wire was introduced through femoral vein and allowed to override the tachycardia with 21 AV block and HR of 160 bpm. ODP was continued for 24 h allowing to wean off the inotropic support. We postulate that ODP can be a safe and less invasive alternative to ECMO in stabilizing infants with cardiogenic shock due to intractable SVTs.Atrial septal defect (ASD) associated with left ventricular (LV) diastolic dysfunction (DD) is rare in children. DD is common in elderly patients undergoing ASD closure. Restrictive physiology among children undergoing percutaneous ASD closure is something unexpected that has not been described before in the literature. Hence, we report a child referred to our center for ASD closure in whom an LV DD has been unmasked with a balloon occlusion test and has been managed with pharmacological preconditioning and subsequent ASD closure with good outcome. Albeit rare, LV DD can occur in children undergoing ASD closure.Cardiac fibromas (CF) are the second most common cardiac tumors in children. They can be aggressive tumors despite their benign histopathologic nature, accounting for the highest mortality rate among primary cardiac tumors. CF usually show a progressive growth and spontaneous regression is rare. Therefore, a complete surgical excision is the preferred therapeutic approach when patients become symptomatic or if mass-related life-threatening complications are anticipated, even in asymptomatic patients. However, some cases are not good candidates for surgical excision due to the impossibility of preserving a normal cardiac anatomy or function after the tumor resection. Orthotopic heart transplantation (OHT) can be an exceptional but adequate alternative for some giant unresectable CF in children. In this article, we report our experience with the case of a 7-month-old infant with a giant unresectable cardiac fibroma who was successfully managed through OHT.
