Remission of type 2 diabetes after Roux-en-Y gastric bypass or sleeve gastrectomy is associated with a distinct glycemic profile.

BACKGROUND
Roux-en-Y gastric bypass (RYGBP) and sleeve gastrectomy (SG) have been associated with a high remission rate of type 2 diabetes mellitus (T2DM). However, whether such remission is associated with full restoration of postprandial glucose profile and/or the potentially nonrestored glycemic profile is associated with altered beta cell function, and relapse of T2DM over time is unknown.


METHODS
Cross-sectional studies comparing (1) glucose and proinsulin/insulin response to a standardized liquid mixed meal (SLMM) challenge (n = 31), (2) glucose response in normal living conditions assessed using continuous glucose monitoring (CGM) (n = 16), and prospective observational study comparing (3) rates of relapse of T2DM after surgery (n = 232) in subjects with remission of T2DM ensuing RYGBP or SG.


RESULTS
In RYGB individuals, SLMM elicited faster and sharper rise in plasma glucose compared with SG, with 88.2% and 42.9% of the study subjects presenting respectively a peak glucose more than 180 mg/dL (all, P < 0.05). During CGM, average percent time in hyperglycemic and hypoglycemic range was larger in RYGBP (respectively, 4.6% and 12.7%) compared with SG subjects (respectively, 0.4% and 3.2%; both P < 0.05). However, (1) no differences were found in fasting or stimulated proinsulin/insulin ratio, and (2) higher rates of T2DM relapse were observed after SG (hazard ratio: 2.339; P = 0.034).


CONCLUSIONS
Remission of T2DM after RYGBP and SG is associated with distinct glycemic profiles. However, longer time spent in hyperglycemia and in hypoglycemia after RYGBP compared with SG is not associated with persistence of altered beta cell function or higher rates of relapse of T2DM over time.
PHYSICO-CHEMICAL ANALYSIS OF SURFACE AND GROUND WATER OF BARGARH DISTRICT, ORISSA, INDIA

The piece of investigation was carried out to study the ground water as well as surface water quality, nutrient status and physico-chemical characteristic of Bargarh district of Orissa, India. The study area is situated between 21 o 36 ’’ E longitude and 176.362 mts above sea level and 59km to west of Sambalpur district. The present work has been conducted by monitoring two types of ground water i.e. dug well water and bore well water of 10 wards of the town as well as 3 types of ponds, viz. temple pond, small community pond & large community pond of the town. Attempts were made to study and analyze the physico-chemical characteristics of the water. Various parameters like Temperature, pH, Total suspended solids, and Total dissolved solids, Alkalinity, Dissolved oxygen, Chemical Oxygen Demand, Nitrate, Chloride, Sodium, Potassium, Phosphate, Fluoride, Total Coli forms(Pond water) etc. give a picture of quality parameter in both dug well and bore well water as well as pond water of the town. By observing the result it can be concluded that the parameters which were taken for study the water quality are below the pollution level for ground water which satisfy the requirement for the use of various purposes like domestic, agricultural, industrial etc. But incase of surface water, the water quality of small community pond are above the permissible limit.

The workload on parallel supercomputers: modeling the characteristics of rigid jobs

The analysis of workloads is important for understanding how systems are used. In addition, workload models are needed as input for the evaluation of new system designs, and for the comparison of system designs. This is especially important in costly largescale parallel systems. Luckily, workload data are available in the form of accounting logs. Using such logs from three different sites, we analyze and model the job-level workloads with an emphasis on those aspects that are universal to all sites. As many distributions turn out to span a large range, we typically first apply a logarithmic transformation to the data, and then fit it to a novel hyperGamma distribution or one of its special cases. This is a generalization of distributions proposed previously, and leads to good goodness-of-fit scores. The parameters for the distribution are found using the iterative EM algorithm. The results of the analysis have been codified in a modeling program that creates a synthetic workload based on the results of the analysis. r 2003 Elsevier Inc. All rights reserved.
Reconstruction of Mandibular Alveolar Ridge Defects for Implant Placement: Critical Review

Background: Dental rehabilitation of partially or totally edentulous patients with oral implants has become a routine treatment modality in the last decades, with reliable long-term results. However, unfavorable local conditions of the alveolar ridge, due to atrophy, periodontal disease, and trauma sequelae may provide insufficient bone volume or unfavorable vertical, horizontal, and sagittal intermaxillary relationships, which may render implant placement impossible or incorrect from a functional and esthetic viewpoint. The aim of the current review is to discuss the different strategies for reconstruction of the alveolar ridge defect for implant placement. Study design: The study design includes a literature review of the articles that address the association between Reconstruction of Mandibular Alveolar Ridge Defects and Implant Placement. Results: Yet, despite an increasing number of publications related to the correction of deficient alveolar ridges, much controversy still exists concerning which is the more suitable and reliable technique. This is often because the publications are of insufficient methodological quality (inadequate sample size, lack of well-defined exclusion and inclusion criteria, insufficient follow-up, lack of well-defined success criteria, etc.). Conclusion: On the basis of available data it is difficult to conclude that a particular surgical procedure offered better outcome as compared to another. Hence the practical use of the available bone augmentation procedures for dental implants depends on the clinician’s preference in general and the clinical findings in the patient in particular. Surgical techniques that reduce trauma, preserve and augment the alveolar ridge represent key areas in the goal to optimize implant results.
Prevention of menstrual migraine with perimenstrual transdermal 17-β-estradiol: a randomized, placebo-controlled, double-blind crossover study.

The effect of treatment with percutaneous E(2) (100 μg/24 h) during 2 weeks perimenstrually on the number and severity of menstrual migraine attacks was studied in 27 women in a randomized, placebo-controlled, double-blind, crossover trial. We were not able to demonstrate any difference between E(2) supplementation and placebo on the number or severity of migraine attacks, but both regimens showed significant effects compared with before treatment. CLINICAL TRIAL IDENTIFICATION NUMBER: NCT00204074.
A Data Warehouse Solution for Analyzing RFID-Based Baggage Tracking Data

Today, airport baggage handling is far from perfect. Baggage goes on the wrong flights, is left behind, or gets lost, which costs a lot of money for the airlines, as well as frustration for the passengers. To remedy the situation, we present a data warehouse (DW) solution for storing and analyzing spatio-temporal Radio Frequency Identification (RFID) baggage tracking data. Analysis of this data can yield interesting results on baggage flow, the causes of baggage mishandling, and the parties responsible for the mishandling(airline, airport, handler,...), which can ultimately lead to improved baggage handling quality. The paper presents a carefully designed data warehouse (DW), with a relational schema sitting underneath a multidimensional data cube, that can handle the many complexities in the data. The paper also discusses the Extract-Transform-Load (ETL) flow that loads the data warehouse with the appropriate tracking data from the data sources. The presented concepts are generalizable to other types of multi-site indoor tracking systems based on Bluetooth and RFID. The system has been tested with large amount of real-world RFID-based baggage tracking data from a major industry initiative. The developed solution is shown to both reveal interesting insights as well as being several orders of magnitude faster than computing the results directly on the data sources.
CloudFilter: practical control of sensitive data propagation to the cloud

A major obstacle for the adoption of cloud services in enterprises is the potential loss of control over sensitive data. Companies often have to safeguard a subset of their data because it is crucial to their business or they are required to do so by law. In contrast, cloud service providers handle enterprise data without providing guarantees and may put confidentiality at risk. In order to maintain control over their sensitive data, companies typically block all access to a wide range of cloud services at the network level. Such restrictions significantly reduce employee productivity while offering limited practical protection in the presence of malicious employees.
 In this paper, we suggest a practical mechanism to ensure that an enterprise maintains control of its sensitive data while employees are allowed to use cloud services. We observe that most cloud services use HTTP as a transport protocol. Since HTTP offers well-defined methods to transfer files, inspecting HTTP messages allows the propagation of data between the enterprise and cloud services to be monitored independently of the implementation of specific cloud services. Our system, CloudFilter, intercepts file transfers to cloud services, performs logging and enforces data propagation policies. CloudFilter controls where files propagate after they have been uploaded to the cloud and ensures that only authorised users may gain access. We show that CloudFilter can be applied to control data propagation to Dropbox and GSS, describing the realistic data propagation policies that it can enforce.
Evolution of multigap superconductivity in the atomically thin limit: Strain-enhanced three-gap superconductivity in monolayer MgB2

Starting from first principles, we show the formation and evolution of superconducting gaps in MgB2 at its ultrathin limit. Atomically thin MgB2 is distinctly different from bulk MgB2 in that surface states become comparable in electronic density to the bulk-like σand π-bands. Combining the ab initio electron-phonon coupling with the anisotropic Eliashberg equations, we show that monolayer MgB2 develops three distinct superconducting gaps, on completely separate parts of the Fermi surface due to the emergent surface contribution. These gaps hybridize nontrivially with every extra monolayer added to the film, owing to the opening of additional coupling channels. Furthermore, we reveal that the three-gap superconductivity in monolayer MgB2 is robust over the entire temperature range that stretches up to a considerably high critical temperature of 20 K. The latter can be boosted to >50 K under biaxial tensile strain of ∼ 4%, which is an enhancement stronger than in any other graphene-related superconductor known to date.

Unsupervised Text Summarization Using Sentence Embeddings

Dense vector representations of words, and more recently, sentences, have been shown to improve performance in a number of NLP tasks. We propose a method to perform unsupervised extractive and abstractive text summarization using sentence embeddings. We compare multiple variants of our systems on two datasets, show substantially improved performance over a simple baseline, and performance approaching a competitive baseline.
Neuronal and glial markers are differently associated with computed tomography findings and outcome in patients with severe traumatic brain injury: a case control study

INTRODUCTION
Authors of several studies have studied biomarkers and computed tomography (CT) findings in the acute phase after severe traumatic brain injury (TBI). However, the correlation between structural damage as assessed by neuroimaging and biomarkers has not been elucidated. The aim of this study was to investigate the relationships among neuronal (Ubiquitin carboxy-terminal hydrolase L1 [UCH-L1]) and glial (glial fibrillary acidic protein [GFAP]) biomarker levels in serum, neuroradiological findings and outcomes after severe TBI.


METHODS
The study recruited patients from four neurotrauma centers. Serum samples for UCH-L1 and GFAP were obtained at the time of hospital admission and every 6 hours thereafter. CT scans of the brain were obtained within 24hrs of injury. Outcome was assessed by Glasgow Outcome Scale (GOS) at discharge and at 6 months.


RESULTS
81 severe TBI patients and 167 controls were enrolled. The mean serum levels of UCH-L1 and GFAP were higher (p < 0.001) in TBI patients compared to controls. UCH-L1 and GFAP serum levels correlated significantly with Glasgow Coma Scale (GCS) and CT findings. GFAP levels were higher in patients with mass lesions than in those with diffuse injury (2.95 ± 0.48 ng/ml versus 0.74 ± 0.11 ng/ml) while UCH-L1 levels were higher in patients with diffuse injury (1.55 ± 0.18 ng/ml versus 1.21 ± 0.15 ng/ml, p = 0.0031 and 0.0103, respectively). A multivariate logistic regression showed that UCH-L1 was the only independent predictor of death at discharge [adjusted odds ratios 2.95; 95% confidence interval, 1.46-5.97], but both UCH-L1 and GFAP levels strongly predicted death 6 months post-injury.


CONCLUSIONS
Relationships between structural changes detected by neuroimaging and biomarkers indicate each biomarker may reflect a different injury pathway. These results suggest that protein biomarkers could provide better characterization of subjects at risk for specific types of cellular damage than that obtained with neuroimaging alone, as well as provide valuable information about injury severity and outcome after severe TBI.
Medical Students' Attitudinal Changes Towards Cadaver Dissection: A Longitudinal Study

BACKGROUND
Recently, not only the medical school curriculum but also medical students' attitude towards cadaver-based learning of anatomy has changed. This investigation is therefore designed to analyse students' attitudes towards human cadaveric dissection before and after exposure to dissection.


METHODS
A longitudinal survey was conducted among second year medical students in 2010 at the college of Medicine and Health Sciences, University of Gondar. All second year medical students (n=147) were included in the study where their attitudes were surveyed at three time points (one week prior to dissection session, a week after the initiation of dissection and eight weeks after the second survey). Three standardized and pretested questionnaires prepared in English were used to collected relevant data from the subjects.


RESULTS
Out of the 147 students 85.7% were males. The subjects' age ranged between 18 and 23 with a mean and standard deviation of 19.5±1 years. This study has revealed that among majority of the students fear and nausea have decreased while their interest and excitement has increased on subsequent exposure to dissection (P<0.05). About 75% of students considered the dissection room as slightly or highly stressful. Smell of the cadaver and eye irritation as a result of the chemicals in it were the major aspects identified as making the dissecting room stressful. The result also showed that almost all (99%) considered cadaver dissection had very important educational value for anatomy learning.


CONCLUSION
In the majority of the students fear and nausea had decreased while interest and excitement had increased on subsequent exposure to dissection. It also showed that chemical odour and eye irritations were the leading factors which create discomfort in the dissection room even though anatomical dissection by itself was not considered as a stressor. Thus, instructors are recommended to adequately prepare students mentally and emotionally before the commencement of the dissection session for an exciting and stress free anatomy learning though dissection.
Automated Versus Manual Blood Pressure Measurement: A Randomized Crossover Trial in the Emergency Department of a Tertiary Care Hospital in Karachi, Pakistan: Are Third World Countries Ready for the Change?

BACKGROUND
Hypertension has proven to be a strong liability with 13.5% of all mortality worldwide being attributed to elevated blood pressures in 2001. An accurate blood pressure measurement lies at the crux of an appropriate diagnosis. Despite the mercury sphygmomanometer being the gold standard, the ongoing deliberation as to whether mercury sphygmomanometers should be replaced with the automated oscillometric devices stems from the risk mercury poses to the environment.


AIM
This study was performed to check the validity of automated oscillometric blood pressure measurements as compared to the manual blood pressure measurements in Karachi, Pakistan.


MATERIAL AND METHODS
Blood pressure was recorded in 200 individuals aged 15 and above using both, an automated oscillometric blood pressure device (Dinamap Procare 100) and a manual mercury sphygmomanometer concomitantly. Two nurses were assigned to each patient and the device, arm for taking the reading and nurses were randomly determined. SPSS version 20 was used for analysis. Mean and standard deviation of the systolic and diastolic measurements from each modality were compared to each other and P values of 0.05 or less were considered to be significant. Validation criteria of British Hypertension Society (BHS) and the US Association for the Advancement of Medical Instrumentation (AAMI) were used.


RESULTS
Two hundred patients were included. The mean of the difference of systolic was 8.54 ± 9.38 while the mean of the difference of diastolic was 4.21 ± 7.88. Patients were further divided into three groups of different systolic blood pressure <= 120, > 120 to = 150 and > 150, their means were 6.27 ± 8.39 (p-value 0.175), 8.91 ± 8.96 (p-value 0.004) and 10.98 ± 10.49 (p-value 0.001) respectively. In our study 89 patients were previously diagnosed with hypertension; their difference of mean systolic was 9.43 ± 9.89 (p-value 0.000) and difference of mean diastolic was 4.26 ± 7.35 (p-value 0.000).


CONCLUSIONS
Systolic readings from a previously validated device are not reliable when used in the ER and they show a higher degree of incongruency and inaccuracy when they are used outside validation settings. Also, readings from the right arm tend to be more precise.
The glass transition in a nutshell: A source of inspiration to describe the subcritical transition to turbulence

The starting point of the present work is the observation of possible analogies, both at the phenomenological and at the methodological level, between the subcritical transition to turbulence and the glass transition. Having recalled the phenomenology of the subcritical transition to turbulence, we review the theories of the glass transition at a very basic level, focusing on the history of their development as well as on the concepts they have elaborated. Doing so, we aim at attracting the attention on the above-mentioned analogies, which we believe could inspire new developments in the theory of the subcritical transition to turbulence. We then briefly describe a model inspired by one of the simplest and most inspiring models of the glass transition, the so-called Random Energy Model, as a first step in that direction.Graphical abstract
Study protocol: cluster randomised controlled trial to assess the clinical and cost effectiveness of a staff training intervention in inpatient mental health rehabilitation units in increasing service users’ engagement in activities

BACKGROUND
This study focuses on people with complex and severe mental health problems who require inpatient rehabilitation. The majority have a diagnosis of schizophrenia whose recovery has been delayed due to non-response to first-line treatments, cognitive impairment, negative symptoms and co-existing problems such as substance misuse. These problems contribute to major impairments in social and everyday functioning necessitating lengthy admissions and high support needs on discharge to the community. Engagement in structured activities reduces negative symptoms of psychosis and may lead to improvement in function, but no trials have been conducted to test the efficacy of interventions that aim to achieve this.


METHODS/DESIGN
This study aims to investigate the clinical and cost-effectiveness of a staff training intervention to increase service users' engagement in activities. This is a single-blind, two-arm cluster randomised controlled trial involving 40 inpatient mental health rehabilitation units across England. Units are randomised on an equal basis to receive either standard care or a "hands-on", manualised staff training programme comprising three distinct phases (predisposing, enabling and reinforcing) delivered by a small team of psychiatrists, occupational therapists, service users and activity workers. The primary outcome is service user engagement in activities 12 months after randomisation, assessed using a standardised measure. Secondary outcomes include social functioning and costs and cost-effectiveness of care.


DISCUSSION
The study will provide much needed evidence for a practical staff training intervention that has potential to improve service user functioning, reducing the need for hospital treatment and supporting successful community discharge. The trial is registered with Current Controlled Trials (Ref ISRCTN25898179).
Robust Direct Torque Control of Synchronous Reluctance Motor Drives in the Field-Weakening Region

A robust field-weakening method for direct-torque-controlled (DTC) synchronous reluctance motors is presented in this paper. The proposed algorithm achieves smooth transition between the constant torque and field-weakening regions. Maximum torque per ampere is utilized below base speed, while both the current and voltage limits of the drive system are satisfied in the field-weakening region. The proposed method is robust to the variations in the machine dq -axis inductances. This ensures the system stability during field-weakening operation, especially along the maximum torque per flux trajectory. The proposed algorithm is incorporated into the duty ratio regulation-based DTC to achieve high-performance torque and flux control in the field-weakening region. Experimental results included in this paper confirm the veracity of the proposed method.
