Evaluation of homoeopathic medicines as add-on to institutional management protocol in Acute Encephalitis Syndrome: An exploratory observational comparative study

Background: Acute Encephalitis Syndrome (AES) treated according to Institutional Management Protocol (IMP) has considerable mortality and morbidity. The study was undertaken to evaluate the effect of homoeopathic treatment (H) as an add-on to IMP (IMP + H) for children affected with AES. Materials and Methods: This was an exploratory observational study carried out in the IPD setting (epidemic ward) of Baba Rhaghav Das Medical College and Nehru Hospital, Uttar Pradesh (July to November 2012) using convenience sampling. Children whose guardians gave consent were treated with IMP + H and rest remained on IMP only. Glasgow outcome scale was used at discharge for the final outcome. Results: 151 children (121 in IMP + H and 30 in only IMP) diagnosed with AES (aged 6 months to 18 years) were enrolled. The results showed 12 (9.9%) death out of 121 children administered IMP + H whereas it was 13 (43%) out of 30 children on IMP alone. Proportional odds analysis with covariate adjustment showed added benefit of Homoeopathy in children with AES as compared to IMP alone (adjusted odds ratio, 0.17, 95% confidence interval 0·06-0.45, P = 0·0001). The most useful medicines are Belladonna, Stramonium, Arsenicum album, Helleborus, Bryonia alba, Sulphur, and Cuprum metallicum. Conclusion: This exploratory observational study suggests reduction of mortality and morbidity with add-on homoeopathic medicine. Further randomized controlled trial study with comparable groups is desirable. If findings are confirmed by subsequent research, add-on Homoeopathy might have relevant implication for its management.
Comparison of Bupivacaine and Bupivacaine with Fentanyl in Continuous Extradural Analgesia during Labour

Sir,—Following the recent publication of our study on extradural analgesia during labour [1], we would wish to notify a case of profound respiratory depression 100 min after the use of bupivacaine and fentanyl in extradural analgesia for Caesarean section. The dose of fentanyl (100 ug) was similar to that used as a loading dose in our study. A detailed case report will follow. We would therefore strongly advise that patients are observed continuously for a period of 2-3 h following the use of extradural bupivacaine and fentanyl, particularly if there has been evidence of an initial high level of local anaesthetic block.
Optimal Bin Packing with Items of Random Sizes III

Consider a probability measure $\mu $ on $[0,1]$ and independent random variables $X_1 , \cdots ,X_n $ distributed according to $\mu $. Let $Q_n = Q_n (X_1 , \cdots ,X_n )$ be the minimum number of unit-size bins needed to pack items of size $X_1 , \cdots ,X_n $. Let $c(\mu ) = \lim _{n \to \infty } {{E(Q_n )} / n}$. In this paper it is proved that the random variable ${{(Q_n - nc(\mu ))} / {\sqrt n }}$ converges in distribution. The limit is identified as a distribution of the supremum of a certain Gaussian process canonically attached to $\mu $.
Gene Expression Profiling of Duodenal Biopsies Discriminates Celiac Disease Mucosa From Normal Mucosa

Celiac disease (CD) is identified by histopathologic changes in the small intestine which normalize during a gluten-free diet. The histopathologic assessment of duodenal biopsies is usually routine but can be difficult. This study investigated gene expression profiling as a diagnostic tool. A total of 109 genes were selected to reflect alterations in crypt-villi architecture, inflammatory response, and intestinal permeability and were examined for differential expression in normal mucosa compared with CD mucosa in pediatric patients. Biopsies were classified using discriminant analysis of gene expression. Fifty genes were differentially expressed, of which eight (APOC3, CYP3A4, OCLN, MAD2L1, MKI67, CXCL11, IL17A, and CTLA4) discriminated normal mucosa from CD mucosa without classification errors using leave-one-out cross-validation (n = 39) and identified the degree of mucosal damage. Validation using an independent set of biopsies (n = 27) resulted in four discrepant cases. Biopsies from two of these cases showed a patchy distribution of lesions, indicating that discriminant analysis based on single biopsies failed to identify CD mucosa. In the other two cases, serology support class according to discriminant analysis and histologic specimens were judged suboptimal but assessable. Gene expression profiling shows promise as a diagnostic tool and for follow-up of CD, but further evaluation is needed.
Analysis of Laminagraphic Motions and Their Values

Introduction THE addition of body-section roentgenography to other diagnostic procedures has definitely enlarged the scope of roentgenologic diagnosis and this new method has already proven useful in many cases. The cardinal principle of body-section roentgenography is that the tube, film, and the body to be roentgenographed shall be in relative motion to one another during exposure. Recently, a variety of apparatus and technics has been presented under different names by various authors: namely, stratigraphy (Vallebona, 15); tomography (Grossmann, 8); planigraphy (Ziedses des Plantes, 18, Andrews, 1); x-ray focusing, vertigraphy (Kieffer, 9); laminagraphy (Kieffer-Moore, 10). (The last method has also been spelled “laminography” by various authors.) Andrews in his original paper called attention to this multiplicity of names and recommended definite uses for them. In order to avoid confusion, and until an official terminology is decided upon, I suggest the following extended classification, based upon hi.
Ground States and Dynamics of Multicomponent Bose-Einstein Condensates

We study numerically the time-independent vector Gross--Pitaevskii equations (VGPEs) for ground states and time-dependent VGPEs with (or without) an external driven field for dynamics describing a multicomponent Bose--Einstein condensate (BEC) at zero or a very low temperature. In preparation for the numerics, we scale the three-dimensional (3d) VGPEs, approximately reduce it to lower dimensions, present a continuous normalized gradient flow (CNGF) to compute ground states of multicomponent BEC, prove energy diminishing of the CNGF, which provides a mathematical justification, and discretize it by the backward Euler finite difference (BEFD), which is monotone in linear and nonlinear cases and preserves energy diminishing property in the linear case. Then we use a time-splitting sine-spectral (TSSP) method to discretize the time-dependent VGPEs with an external driven field for computing dynamics of multicomponent BEC. The merits of the TSSP method for VGPEs are that it is explicit, unconditionally stable,.
Tai Chi for Chronic Pain and Arthritis

Summary Tai Chi is an ancient Chinese martial art that is currently practiced by millions of people worldwide. Because Tai Chi is a gentle, slow movement exercise system that incorporates deep, rhythmic breathing, it may be appropriate for patients experiencing chronic pain and arthritis. Although western research is just beginning to evaluate the therapeutic importance of Tai Chi, the small percentage of clinical studies that have been conducted have found beneficial effects in several areas of functioning in the studied populations. Reducing falls in the elderly, improved balance, improved strength and flexibility, increased sense of confidence, and improved emotional and psychologic well-being are some of the positive results to date. The management of chronic pain and arthritis presents complex issues for the health care practitioner. Incorporating Tai Chi into traditional medical management may provide an option for patients who face physical and emotional challenges from chronic illness.
Approximation Algorithm for the Mixed Fractional Packing and Covering Problem

We propose an approximation algorithm based on the Lagrangian or price-directive decomposition method to compute an $\epsilon$-approximate solution of the mixed fractional packing and covering problem: find $x \in B$ such that $f(x) \le (1+\epsilon) a$, $g(x) \ge (1-\epsilon) b,$ where $f(x),g(x)$ are vectors with $M$ nonnegative convex and concave functions, $a$ and $b$ are $M$-dimensional nonnegative vectors, and $B$ is a convex set that can be queried by an optimization oracle. We propose an algorithm that needs only $O(M \epsilon^{-2} \ln (M\epsilon^{-1}))$ iterations or calls to the oracle. The main contribution is that the algorithm solves the general mixed fractional packing and covering problem (in contrast to pure fractional packing and covering problems and to the special mixed packing and covering problem with $B = {\rz}^N_+$) and runs in time independent of the so-called width of the problem.
A Revised Dual Projective Pivot Algorithm for Linear Programming

We revise the dual projective pivot algorithm using sparse rectangular LU factors. In each iteration, the proposed algorithm solves at most three triangular systems, while simplex algorithms solve four. Instead of the classical basis, it uses a so-called pseudobasis (a rectangular matrix having fewer columns than rows), thereby solving smaller linear systems with a potentially improved stability compared to simplex algorithms. Most importantly, it generates good search directions at a low cost. We report encouraging computational results on a set of 50 Netlib standard test problems as well as a set of 15 much larger real-world problems. A code named RDPPA 1.10 based on the proposed algorithm outperformed MINOS 5.51 significantly in terms of both iterations and run time. In particular, it appears that a high proportion of degenerate iterations need not imply many total iterations (contradicting the common belief).
Dispersion Relation Analysis of the $P^NC_1 - P^_1$ Finite-Element Pair in Shallow-Water Models

Shallow-water models typically employ gridpoint, finite, and spectral-element techniques. For most of these methods the coupling between the momentum and continuity equations is a delicate problem and usually leads to spurious solutions in the representation of inertia-gravity waves. The spurious modes have a wide range of characteristics and may take the form of pressure (surface-elevation), velocity, and/or Coriolis modes. The modes usually cause aliasing and an accumulation of energy in the smallest-resolvable scale, leading to noisy solutions. The triangular finite-element pair $P^{NC}_{1}-P^{}_{1}$ is shown to "properly" model the dispersion of the inertia-gravity waves, and this is achieved at a reasonable computational cost compared to traditional finite-difference schemes. Two tests are proposed. The first test examines the propagation and dispersion of fast surface gravity waves in a circular basin and their reflection at the lateral boundary. In the second test, results of the Stommel problem are presented using the proposed finite-element pair and are compared with those obtained with the C- and CD-finite-difference grids. They illustrate the promise of the proposed approach.
Postural Control as a Probe for Cognitive State: Exploiting Human Information Processing to Enhance Performance

The battlefield of the future will require the warfighter to multitask in numerous ways, seriously taxing the cognitive and perceptual capabilities of even the most advanced warrior. A principal concern in developing a better understanding of how current and proposed computational technologies can supplement and augment human performance in this and other environments is determining when such assistance is required. This challenge can be parsed into 2 components: determining what set of measurements accurately reflects cognitive state, and identifying techniques for synthesizing this set of measurements into a single collective cognitive state variable. The primary thesis of this proposal is that automatic human behavioral responses serve as inherent probes for cognitive state. Further, the human perception-action system is uniquely designed to capture, process, integrate, and act on an extraordinarily diverse range of information freely available in the natural environment. Together, this system and the surrounding environment which acts on it-and on which the system acts-form a dynamic coupling. Under normal conditions these couplings remain intact. When stressed, these couplings become degraded. Based on this understanding, the authors propose a unique suite of Cognitive Workload Assessment (CWA) tools, based on real-time measurements of postural control that can serve as both a stand-alone indicator of cognitive state as well as a cueing filter for engaging other CWA sensor suites that are currently under development.
Factors Influencing the Nutritional Health and Food Choices of African American HIV-Positive Marginally Housed and Homeless Female Substance Abusers

The toll of HIV/AIDS and drug abuse on economically disadvantaged women of color in the United States is a public health problem of epidemic proportions. Malnutrition, believed to be pervasive in this population, exacerbates the devastating health effects of addiction and HIV. This study documented dietary deficiencies in this population and examined factors influencing the food choices and eating patterns of marginally housed and homeless African American HIV-positive substance abusing women. Data were collected from 28 women ages 19–55 using two 24-hour dietary recalls and a semi-structured interview guide. Data revealed multiple nutritional intake hazards including skipped meals, substitution of carbohydrate-laden foods for dairy foods rich in animal fat and proteins, and an absence of raw fruits and vegetables indicative of deficiencies in key macro- and micronutrients. Food risks were increased for homeless women who were more likely to lack public assistance, have difficulty accessing free food service, and frequently eating food from dumpsters. Qualitative data analysis of interviews generated three major themes describing the context in which nutritional deficiencies emerged: (1) diet-disease and food-safety misconceptions; (2) socio-cultural and lifestyle barriers; and (3) lack of personal resources and neighborhood food availability and affordability. The relevance of these findings to nutrition intervention programs for this population is discussed.
Estudo comparativo da velocidade e atenuação ultra-sônica na avaliação da consolidação óssea

Objectives: The objective of this study was to compare the in vitro ultrasonic velocity and attenuation in bone healing evaluation. Methods: Seventeen sheep weighting 37 kg in average were used, being divided into two groups of five animals each and one group of seven animals, according to the postoperative follow-up time (30, 60 and 90 days, respectively). Osteotomies were performed on the right tibiae and the intact left tibiae of the 17 animals were used as control. The healing process was monitored with conventional conventional radiographs taken at two-week intervals. The animals were sacrificed at the end of the corresponding follow-up period and both right and left tibiae were removed for in vitro underwater and contact ultrasound evaluations. The transverse and longitudinal ultrasound propagation velocity (USPV) and the broadband ultrasound attenuation (BUA) were measured and correlated. Results: USPV increased with the progression of the healing process, while BUA decreased, with significant differences between the experimental and control groups and between the experimental groups, for most of the comparisons. Conclusion: It was concluded that the method using ultrasound as employed in this investigation is feasible and reliable for evaluating cortical bone healing.
Environments for Information Systems Implementation in Small Businesses

Top management support and external information systems (IS) expertise, in the forms of consultants and vendors, have been identified as 2 key factors for effective IS implementation in small businesses. This article proposes a framework for IS implementation in small businesses. The framework is based on high-low combinations of top management support and external IS expertise to characterize 4 IS implementation environments. The framework was tested with a questionnaire survey of 114 small businesses in Singapore. Interviews were also conducted with 67 of these small businesses. IS implementation success was measured by user satisfaction, organizational impact, and overall IS effectiveness. The results show that the most effective IS implementation environment is one in which both top management support and external IS experts work as a team. However, notwithstanding the lack of top management support, IS implementation can still be effective if the quality of external IS expertise is high.
Reversible Turing Machines and Polynomial Time Reversibly Computable Functions

The reversible Turing machine (i.e., r-machine) was introduced initially by C. H. Bennett [IBM J. Res. Develop. , 6 (1973), pp. 525–532]. In the first part of the paper a convenient representation of r-machines is introduced by means of diagrams. By using this method the following theorem can be proved: the invertible partial functions are exactly those that can be computed without surplus information by r-machines. Therefore the following problem is pointed out: are the invertible functions that can be computed in polynomial time also r-computable in polynomial time? In the second part of the work this open question is connected with the problem P = NP and with the problem of the existence of “one-way” bijections.
Factors predicting program fidelity and delivery of an early intervention program for first episode psychosis in rural Australia

Abstract This study evaluated the sustainability of the Southern Area First Episode (SAFE) program - an early intervention for psychosis service modified to a specialist-within-generalist-team approach for a rural mental health service. The study also aimed to identify the factors that influence the fidelity of program delivery. A retrospective audit of the files of all people between the age of 15 and 25 years seen by three clinical teams was undertaken two years after the program was implemented. At audit, 43 of the 225 files reviewed were considered suitable for SAFE although only a quarter of these were identified as early intervention clients at assessment. There was considerable variability in delivery of the early intervention practices to suitable clients. Rates of delivery of the medical aspects of care ranged from 61% to 81% while less standard care components of early intervention such as psychoeducation, cognitive-behavioural intervention and outcome monitoring ranged from 20% to 33%. An assessment diagnosis of a psychotic disorder predicted the number of early intervention components delivered, but age, gender, phase of illness and severity were not predictive. Registration on SAFE was the strongest predictor of overall program fidelity. The results indicate that the specialist-within-generalist-team approach can be an effective model of early intervention for psychosis in settings where dedicated specialist teams are not appropriate, provided that prominent service identification processes and advocacy to ensure the ongoing visibility of the program are in place.
CONSTRUCT VALIDATION OF THE COMREY PERSONALITY SCALES.

To investigate the construct validity of the Comrey Personality Scales, this personality test and a biographical data inventory inquiring about past and present life circumstances were administered to 209 volunteer U.C. L.A. students. Biographical data variables were correlated with scores on the eight personality scales. Personality scale score estimates by the authors, based on examination of the respondents' biographical data responses, were also correlated with actual scale scores. The personality scales which received the best confirmation were Social Conformity vs Rebelliousness and Orderliness vs. Lack of Compulsion. Support for the construct validity of the other personality scales varied from moderate to negligible.
Current Coupling of Drift-Diffusion Models and Schrödinger-Poisson Systems: Dissipative Hybrid Models

A one-dimensional coupled drift-diffusion dissipative Schrodinger model (hybrid model) is mathematically analyzed. The device domain is split into two parts: one in which the transport is well described by the drift-diffusion equations (classical zone) and another in which a quantum description via dissipative Schrodinger equations (quantum zone) is used. Both system are coupled such that the continuity of the current densities is guaranteed. The electrostatic potential is self-consistently determined by Poisson's equation on the whole device domain. We show that the hybrid model is well posed, and we prove existence of solutions and show their uniform boundedness, provided the distribution functions satisfy a so-called balance condition. The current densities are different from zero in the nonequilibrium case and are uniformly bounded.
Numerical Analysis of Convection-Diffusion-Reaction Problems with Higher Order Characteristics/Finite Elements. Part I: Time Discretization

In this paper a higher order characteristics time discretization scheme is analyzed for a variable coefficient convection-(possibly degenerate)diffusion-reaction equation with mixed Dirichlet-Robin boundary conditions. First, the proposed second order time discretization scheme is rigorously introduced for exact and approximate characteristics. Next, under not very restrictive hypotheses on the data, the $l^{\infty}(L^2)$ stability is proved and $l^{\infty}(L^2)$ error estimates of order $O(\Delta t^2)$ are obtained. Lagrange-Galerkin schemes using different finite elements spaces will be analyzed in the second part of this work [to appear in SIAM J. Numer. Anal. ], where quadrature formulas are proposed for practical implementation.
Estudo anatômico do terço proximal do fêmur: impacto femoroacetabular e o efeito cam

OBJETIVO: Analisar as variacoes anatomicas da extremidade proximal do femur que pudessem desenvolver o impacto femoroacetabular. METODOS: Foram utilizados 199 especimes anatomicos de femures esqueleticamente maduros. Os femures foram medidos para determinar o ângulo da anteversao do colo femoral, ângulo cervicodiafisario, esfericidade da cabeca femoral em ântero-posterior e supero-inferior, ângulo entre a epifise e o colo femoral anterior, ângulo entre a epifise e o colo em perfil, distância em ântero-posterior a 5mm da juncao cabeca e colo e distância em ântero-posterior da base do colo. RESULTADOS: Observou-se que o subgrupo com impacto apresentou diâmetro da juncao a 5mm (p = 0,0001) e cam-cabeca (%) (p = 0,0001) significativamente maiores e base-cam (%) (p = 0,0001) significativamente menor que o subgrupo sem impacto. Identificou-se que cam-cabeca (%) > 80 e base-cam (%) < 73 foram os pontos otimos para o impacto. CONCLUSAO: O estudo mostrou que o efeito cam, causado por variacoes anatomicas da extremidade proximal do femur, se concentrou na juncao cabeca-colo e base do colo-juncao cabeca-colo. Esses indices podem ser fatores preditivos do impacto.
Survival after treatment with curative intent for hepatocellular carcinoma among patients with vs without non‐alcoholic fatty liver disease

Non‐alcoholic fatty liver disease (NAFLD) is expected to become a leading aetiology of hepatocellular carcinoma (HCC)‐related mortality in the United States. HCC treatments with curative intent (OLT, orthotopic liver transplantation; resection; RFA, radiofrequency ablation) can improve survival in carefully selected patients.
