Clinical Profile of Child and Adolescent (≤16 years) Psychotic Disorders at a Tertiary Care Centre In India

Background: Over past two decades, there is an increasing recognition that the psychotic disorders can begin in children at a very young age. Only a few prior studies from India have explored the clinical profile of non-affective psychotic disorders at a younger age. Aims: The study aims to describe the clinical profile of child and adolescent (≤16 years) psychotic disorders. Methods: The study was conducted as a three-year descriptive, retrospective review. All the patients aged ≤16 years, with a diagnosis of Schizophrenia and other psychotic disorders as per Diagnostic and Statistical Manual, 4 edition Text Revision (DSM-IV TR) criteria who presented to the weekly child and adolescent psychiatry clinic at All India Institute of Medical Sciences, New Delhi were included. Relevant information was retrieved on a semi-structured datasheet. Results: The clinic prevalence for schizophrenia and other psychotic disorders was found to be 2.47% (40/1618), of which five patient records were either unavailable or inadequate for inclusion. The mean age was 13.97(±1.46) years with an equal representation of males and females. A very early-onset (≤12 years) was present in 48.3% of the sample. Median duration of psychotic illness was 12 months (0.1-48 months) and majority (94.3%) had a continuous course. Family history was positive for psychiatric illness in 22.9%, while an identifiable psychosocial stressor was temporally related in 17.1% of sample. A comorbid psychiatric disorder was present in 14.5%, commonest being subnormal intellectual functioning. Auditory hallucinations appeared to be a common (51.5%) symptom, however these were evident primarily from patient’s behavior rather than self-report in over half of them. Visual hallucinations with ghost or animal theme were present in 17.1% and delusions were manifested by 40% of sample. Disorganized speech and catatonia were less frequent. Nearly 17.1% of sample left school after onset of psychosis and all patients showed some disruption in social, inter-personal and academic functioning. Conclusion: The present study adds to the limited literature on clinical presentation and phenomenology of early-onset psychotic disorders in Indian population.
Personalized immunotherapy in colorectal cancer

ABSTRACT The fields of cancer immunology and immunotherapy have made dramatic progress in the past 20 years. Various approaches to cancer immunotherapies, including cancer vaccines using peptides, proteins, DNA, and dendritic cells, have been developed to activate antigen-specific immune cells and their efficacy has been clinically examined. Herein, we summarize previously performed clinical trials of various immunotherapies against colorectal cancer (CRC), including our own novel immunotherapeutic approach, the “personalized peptide vaccine”, in which human leukocyte antigen (HLA)-matched vaccine peptides are selected based on pre-existing host immunity before vaccination. In the near future, neoepitopes identified through massive DNA sequencing of the genetic alterations in tumor cells, combined with robust T cell epitope predictions in each patient might be targeted as a personalized immunotherapy for CRC.
Review: The relationships among depression, self-care agency, self-efficacy and diabetes self-care management

People with diabetes are twice as likely to suffer depression as the general population. Depression in turn is known to affect the self-care management behaviours of people with diabetes (Katon et al., 2004). The study by Gharaibeih et al. shows how complex the facets of depression, self-efficacy, self-care agency, diabetes knowledge and diabetes self-care management (DSCM) are. In this study, self-efficacy involves diabetics’ belief in their ability to perform self-care, whereas self-care agency relates to the actual ability to do this. DSCM involves following a healthy diet, exercise, medication and blood sugar testing. This study recruited from outpatients and community sites in the mid western states of America. In attending these appointments, the participants demonstrate that even if they have depression, they are still engaging in their treatment plans. It is worth considering for those patients who miss their appointments whether depression is also a factor in their non-attendance. The research included a greater percentage of males, with a mean age of 46 years. In middle-aged males, the female partner may well be the person who is doing the cooking. It raises the question that, if considering self-agency and DSCM, the involvement of ‘significant others’ (loved one, family, friend) should be considered. In clinical practice in the UK, I have found that for middle-aged and older couples, it is often the female in the partnership who is choosing the food and preparing and cooking the meals. They can also sometimes be involved in the medication management of their diabetic male partner, working out carbohydrate levels and insulin doses. In addition, if the significant others do exercise, this may have some influence on whether the diabetic person engages in this aspect of DSCM. It may be that, when considering self-efficacy, self-care agency and DSCM, diet and exercise can be impacted by these significant others. It is interesting to note in this study that race and educational level did not affect DSCM, as it has in other studies (Harris, 2008; Polzer and Miles, 2007). It was also found that the years of having had diabetes was a significant predictor of higher DSCM. Thus, it raises the
Prognostic Value of Bone Markers in Patients with Carcinoma

Background: We investigated the usefulness of bone markers, respectively Alkaline Phosphatase (AP) and Tartrat Resistant Acid Phosphatase 5b (TRACP 5b) for diagnosis, treatment and monitoring of patients with carcinoma of different origin. AP is a marker of bone formation, while TRACP 5b is a marker of bone resorption. The isoform 5b of the enzyme TRACP is expressed by osteoclasts and can be measured in blood. Objectives: The aim of this study was to evaluate the prognostic value of the bone markers AP and TRACP 5b to detect bone metastasis and pathological bone metabolism. Materials and Methods: Our study comprised 101 patients with positive tumor markers. Sera of these patients were collected and the bone markers AP and TRACP 5b were determind. TRACP 5b was measured by a colorimetric test which determines the TRACP 5b by using the phophatase activity of this enzyme by dephosphorylation of p-Nitrophenylphosphate (pNPP). The test is a two site immunoassay by Medac Diagnostika, Germany. Results: The sensitivity of AP in our study to detect bone metastasis is 52.9%, the specificity is 53.9%. TRACP 5b shows a sensitivity of 64.7% and a specificity of 70.9%. An elevated TRACP 5b activity is associated significantly with bone metastasis in our study groups (p=0.01). In patients with chronic elevated levels of liver enzymes we could see a significant elevation of TRACP 5b (p=0.005). Conclusion: In conclusion TRACP 5b is more sensitive and specific to detect bone metastasis and bone turnover than the Alkaline Phosphatase. In patients with multimorbidity the origin of AP is not clear due to its multiorganic appearance. The levels of TRACP 5b are elevated in patients with bone metastasis and in patients with chronical dysfunction of the liver. TRACP 5b might be helpful in the diagnostic procedure of tumor-patients to detect bone metastasis. Moreover TRACP 5b seems to be helpful to indicate oncological patients with early dysfunctions in bone metabolism and helps to induce early treatment to these patients.
Update of D-dimer testing1)

Abstract D-dimer concentrations are elevated in a variety of clinical situations with hypercoagulability, such as venous thromboembolism (VTE), disseminated intravascular coagulation (DIC), ischemic cardiopathy, stroke, acute aortic dissection, malignomas, pregnancy, after surgery, traumas, and burns. D-dimer testing has become an essential tool for the diagnosis of VTE and pulmonary embolism because of its high negative predictive value, especially when used in conjunction with a clinical pretest score. D-dimer testing can be used for the diagnosis of DIC and other thrombotic diseases. It is also helpful for risk stratification in coronary artery disease, in first and recurrent thrombotic events, and for the timing of the duration of oral anticoagulation after a first episode of VTE. The use of D-dimer testing is limited in certain clinical conditions in which elevated D-dimer concentrations render the test unsuitable for the detection of acute thrombotic events.
EXCITATION SPECTRUM AND COLLECTIVE MODES OF COMPOSITE FERMIONS

According to the composite fermion theory, the interacting electron system at filling factor $\nu$ is equivalent to the non-interacting composite fermion system at $\nu^*=\nu/(1-2m\nu)$, which in turn is related to the non-interacting electron system at $\nu^*$. We show that several eigenstates of non-interacting electrons at $\nu^*$ do not have any partners for interacting electrons at $\nu$, but, upon composite fermion transformation, these states are eliminated, and the remaining states provide a good description of the spectrum at $\nu$. We also show that the collective mode branches of incompressible states are well described as the collective modes of composite fermions. Our results suggest that, at small wave vectors, there is a single well defined collective mode for all fractional quantum Hall states. Implications for the Chern-Simons treatment of composite fermions will be discussed.
Evaluation of bone mineral density and metabolic abnormalities associated with low-energy hip fractures

Background Low-energy hip fractures are markers for osteoporosis. Despite a recent call for better evaluation of this issue, there is a lack of data regarding the metabolic abnormalities found in these patients and how it relates to their bone density. Additionally, no clear guidelines have been published for the evaluation of osteoporosis in these patients. We characterize the metabolic abnormalities seen in this patient population and suggest an effective screening protocol. Methods Thirty-one patients with low-energy hip fractures not receiving osteoporosis treatment were evaluated with bone density scans and a serum metabolic evaluation consisting of a 25-hydroxyvitamin D level, parathyroid hormone level, and calcium level. The relationship of metabolic abnormalities to bone density values was evaluated. Results Most of the patients presenting with low-energy hip fractures had metabolic abnormalities associated with low bone density. The femoral neck T-scores averaged −2.3. Fifty-three percent (16/30) of patients had low levels of vitamin D and 83% (25/30) of patients had evidence of secondary hyperparathyroidism (PTH >25 nleq/ml). We also found relatively poor correlations of bone density T-scores to parathyroid hormone and vitamin D levels (r=−0.38 and −0.05). Conclusion Most patients presenting with low energy hip fractures have severe metabolic abnormalities associated with low bone density. Due to the poor correlation between bone density T-scores and the serum levels of parathyroid hormone and vitamin D, appropriate osteoporosis evaluation of this patient population requires both bone density evaluation and serum metabolic evaluation of 25-hydroxyvitamin D, PTH, and calcium levels.
Galactic Dynamics: Second Edition

T wo of the world's leading astrophysicists, James Binney and Scott Tremaine, here present a comprehensive review of the theory of galactic dynamics at a level suitable for both graduate students and researchers. Their work in this volume describes our present understanding of the structure and dynamics of stellar systems such as galaxies and star clusters. Nicknamed " the Bible of galactic dynamics, " this book has become a classic treatise, well known and widely used by researchers and students of galactic astrophysics and stellar dynamics. Praised for its modern approach, as well as for the rigor and exemplary clarity with which the authors handle the material in this book, Galactic Dynamics includes classic results and data while also reflecting the many recent developments in the field. The authors maintain an effective style of exposition throughout, keeping clear what is present knowledge and what is still speculation, while allowing the reader to grasp an overview of the subject before following through (where needed) with the mathematical detail. Most of the astronomical community since the late s was introduced to galactic dynamics through Galactic Dynamics, and it remains the most widely used graduate textbook in galactic astrophysics today. No other book gathers together and presents our current understanding of the field in such a clear and concise way. Through this approach, Binney and Tremaine succeeded in creating a classic reference of enormous pedagogic value.   (Click here to view our web site description.)

AIDS and the Nervous System

Any book on the neurology of AIDS is probably doomed to leg behind the fast-changing clinical and mearch picture of this fatal retroviral illness. This book, however, does remarkably well in updating the reader on the recent advances in characterization of the major neurologic complications of AIDS-infectious and neoplastic. It includes references to articlea published jut a few month prior to the book’s own publication date. AIDS and the Nervous System contains chapters on areas of the nervous syatem targeted by the AIDS virue: central nervous system, peripheral nervous system, and eye. In addition, it subdivides neurologic complications into those caused by viral and nonviral infections as well as primary HIV infection alone. As an introduction, the editors present sobering statistical forecasts on the prevalence of AIDS, which, assuming no change in the epidemiology of the disease and no effective therapy, will be the fourth leading cause of death in the US by 1991. The yearly incidence of HIV encephalopathy, the most common neurologic manifestation, will far exceed the yearly incidence of multiple sclerosis by the same year. Because the editors are West Coast-based, the bulk of their statistics are derived from the best-studied risk group for HIV infection: homosexual men. There is less information on the spectrum of dieegee in IV drug abusers and almost none on AIDS in women and pregnancy-in fairness, arean where, as yet, few data are available. In addition, there is no discussion of HIV myopathy. But, in general, this book is an invaluable reference for neurologists and internista. It is a thorough overview of an illness which has, or will, become a part of the practice of neurology in the 198oa.
The Theory of Complex Angular Momenta

This book provides a unique and rigorous introduction to the theory of complex angular momenta, based on the methods of field theory. It comprises an English translation of the series of lectures given by V.N. Gribov in 1969, when the physics of high energy hadron interactions was being created. Besides their historical significance, these lectures contain material which is highly relevant to research today. The basic physical results and the approaches Gribov developed are now being rediscovered in a new context: in the microscopic theory of hadrons provided by quantum chromodynamics. The ideas and calculation techniques presented in this book are useful for analysing high energy hadron scattering phenomena, deep inelastic lepton–hadron scattering, the physics of heavy ion collisions, and kinetic phenomena in phase transitions, and will be instrumental in the analysis of electroweak processes at the next generation particle accelerators, such as LHC and TESLA.

Treatment of Brain Arteriovenous Malformations: A Systematic Review and Meta-Analysis

TIA or ischemic stroke) and arteriographically confirmed AICOA at 2 years’ follow-up. The study was conducted at 49 clinical and 18 PET centers in the United States and Canada between 2002 and 2012. Of the 195 patients participating, 97 were randomized to surgery and 98 to nonsurgery. The primary end point for the nonsurgical group and those randomized to surgery, who did not undergo surgery, was death from randomization to randomization plus 30 days and ipsilateral ischemic stroke within 2 years of randomization. The remarkable feature of the study was that it was terminated prematurely because of futility. Once again, a randomized open-label, blinded-adjudication trial confirms that EC-IC bypass surgery offers no additional benefit to optimal medical therapy in patients with symptomatic carotid occlusive disease. One hopes that the trial results will save patients being offered a procedure that is less effective than medical management. The timely (G4.5 hours from stroke onset) administration of intravenously administered tissue plasminogen activator remains the cost-effective Food and Drug AdministrationYapproved treatment for patients with ischemic stroke.
Serum Alanine Transaminases and Lipid Profile in Type 2 Diabetes Mellitus Indian Patients

Background: Individuals with type 2 diabetes mellitus (T2DM) have high prevalence of liver diseases due to underlying insulin resistance. Deranged lipoprotein metabolism in insulin resistant state also result in hepatic cell injury. Present study evaluated serum Alanine Transaminases (ALT) and lipid profile in diagnosed cases of T2 DM. Methods: Present 2 groups cross sectional study enrolled 90 patients of T2DM 90 healthy age and sex matched controls. Demographic data and anthropometric measures were recorded from all participants. After overnight fast, blood samples were collected and assayed for serum ALT, cholesterol, triglycerides, and low and high density lipoproteins. Results: Highly significant difference in mean value of BMI (27.3+/-3.8Vs21.7+/-2.4 p<0.05), waist circumference (96+/7Vs82+/-6 p<0.001) and waist: hip ratio (1.3+/-0.4Vs0.7+/-0.3 p<0.001) was observed in cases compared to controls. In the cases we found significantly raised cholesterol (183.5+/20.2Vs 151.3+/-15.2p<0.05), triglyceride (195.4 ± 35.3Vs 92.5+/23.7 p<0.001), LDL (115.4+/-18.5 Vs 83.4+/-10.2 p<0.001), ALT (71.65+/-23.3 Vs 28.34+/11.34 p<0.001) and significantly low levels of serum HDL (35.3+/-5.4 Vs 51.5+/-6.5 p<0.001). Serum ALT was positively correlated with BMI, waist: hip, triglycerides, LDL and negatively with HDL. Conclusion: DM has been proposed as a risk factor for chronic liver diseases and hepatocellular cancer. Screening of T2DM patients with simple, inexpensive, easy to measure and internationally standardized parameter serum ALT should be highly recommended. Early detection of liver abnormality and intervention will help to prevent further progression to liver cirrhosis and chronic liver disease.
Effective Orthorhombic Anisotropic Models for Wavefield Extrapolation

Effective Orthorhombic Anisotropic Models for Wavefield Extrapolation Wilson Ibanez Jacome Wavefield extrapolation in orthorhombic anisotropic media incorporates complicated but realistic models, to reproduce wave propagation phenomena in the Earth’s subsurface. Compared with the representations used for simpler symmetries, such as transversely isotropic or isotropic, orthorhombic models require an extended and more elaborated formulation that also involves more expensive computational processes. The acoustic assumption yields more efficient description of the orthorhombic wave equation that also provides a simplified representation for the orthorhombic dispersion relation. However, such representation is hampered by the sixth-order nature of the acoustic wave equation, as it also encompasses the contribution of shear waves. To reduce the computational cost of wavefield extrapolation in such media, I generate effective isotropic inhomogeneous models that are capable of reproducing the first-arrival kinematic aspects of the orthorhombic wavefield. First, in order to compute traveltimes in vertical orthorhombic media, I develop a stable, efficient and accurate algorithm based on the fast marching method. The derived orthorhombic acoustic dispersion relation, unlike the isotropic or transversely isotropic one, is represented by a sixth order polynomial equation that includes the fastest solution corresponding to outgoing P-waves in acoustic media. The effective velocity models are then computed by evaluating the traveltime gradients of the orthorhombic traveltime solution, which is done by explicitly solving the isotropic eikonal equation for the corresponding inhomogeneous isotropic velocity field. The inverted effective velocity fields are source dependent and produce equivalent first-arrival kinematic descriptions of wave propagation in orthorhombic media. I extrapolate wavefields in these isotropic effective velocity models using the more efficient isotropic operator, and the results compare well, especially kinematically, with those obtained from the more expensive anisotropic extrapolator.
