Abstract

Currently, the search and study of new biological markers that can assist in the early diagnosis of cardiovascular diseases, serving as a laboratory tool for assessing the efficiency of ongoing therapy and being a prognostic criterion of possible clinical outcomes and a significant indicator in risk stratification, remain relevant. Two decades have passed since fibroblast growth factor 21 (FGF21), the 21st member of the FGF family, was identified and cloned. FGF21 is a secreted protein that acts as a metabolic regulator and participates in glucose homeostasis, ketogenesis, and regulation of insulin sensitivity. FGF21 expression is controlled by PPAR alpha receptor, which activates peroxisome proliferation. The liver is the main site of FGF21 production. Extrahepatic tissues such as white adipose tissue, brown adipose tissue, and skeletal muscle also express FGF21. Human FGF21 contains 209 amino acids, whereas the mouse counterpart has 210. Mouse and human FGF21 have 75% homology. Endocrine actions of FGF21 include enhancing glucose uptake by adipocytes of white adipose tissue via a unidirectional glucose transporter protein and activating the thermogenic function of brown adipose tissue. Furthermore, FGF21 has autocrine/paracrine effects, such as the induction of hepatic ketogenesis. FGF21 affects target cells with the participation of FGFR1 and FGFR4 receptors and beta-Klotho, a single-pass transmembrane protein that functions as an obligate cofactor of FGF21 signaling. Animal studies have clearly demonstrated that FGF21 acts directly on cardiac tissue, preventing the development of cardiac hypertrophy and reducing post-infarction damage and diabetic cardiomyopathy. Accumulating data emphasize the value of FGF21 as a new biological marker for diagnosis and prognosis assessment in patients with cardiac issues. Moreover, the role of FGF21 in heart diseases is very interesting because of its cardioprotective effects. Future large-scale prospective studies are necessary to confirm of the diagnostic, predictive, and possibly therapeutic role of this marker.

Abstract

The importance of host-associated microorganisms and their biotic interactions for plant health and performance has been increasingly acknowledged. Protists, main predators and regulators of bacteria and fungi, are abundant and ubiquitous eukaryotes in terrestrial ecosystems. Protists are considered to benefit plant health and performance, but the community structure and functions of plant-associated protists remain surprisingly underexplored. Harnessing plant-associated protists and other microbes can potentially enhance plant health and productivity and sustain healthy food and agriculture systems. In this review, we summarize the knowledge of multifunctionality of protists and their interactions with other microbes in plant hosts, and propose a future framework to study plant-associated protists and utilize protists as agrifood tools for benefiting agricultural production.

Currently, medical students and professionals have an enormous opportunity to keep them always updated with the exponential growth of knowledge because of potential progression of Internet throughout the world that enables them to become a lifelong learner. Internet addiction is a widespread phenomenon among students and academicians at universities in Malaysia. Students use the Internet for recreational purpose and personal and professional development. The Internet has become an integral part of day-to-day life of the university students, including medical students. The aim of the present study was to examine the Internet use and addiction among students of Universiti Sultan Zainal Abidin, Malaysia.Methods: This was a cross-sectional study in which a questionnaire, Internet Addiction Diagnostic Questionnaire, developed by the Center for Internet Addiction, USA, was used. One hundred forty-nine medical students of Universiti Sultan Zainal Abidin participated in this study. Data were analyzed using Statistical Package for the Social Sciences software.Results: The mean scores were 44.9±14.05 and 41.4±13.05 for male and female participants, respectively, which indicated that both the genders were suffering from mild Internet addiction.Conclusion: This study shows almost similar level of Internet usage among medical students irrespective of their socioeconomic background, with no statistically significant (p>0.05) differences, except among the years of study (p=0.007). Overall, from the research data and having worked with this cohort very closely, Universiti Sultan Zainal Abidin medical students can be labeled as wonted and recurring users of the Internet. Nevertheless, it is very difficult to define as Internet addicts or pathological users of the Internet because of small sample size and cross-sectional study.

Abstract

Hydrogen sulfide (H2S) is a gasotransmitter that exerts a multitude of functions in both physiologic and pathophysiologic processes. H2S-synthesizing enzymes are increased in a variety of human malignancies, including colon, prostate, breast, renal, urothelial, ovarian, oral squamous cell, and thyroid cancers. In cancer, H2S promotes tumor growth, cellular and mitochondrial bioenergetics, migration, invasion, angiogenesis, tumor blood flow, metastasis, epithelia–mesenchymal transition, DNA repair, protein sulfhydration, and chemotherapy resistance Additionally, in some malignancies, increased H2S-synthesizing enzyme expression correlates with a worse prognosis and a higher tumor stage. Here we review the role of H2S in cancer, with an emphasis on the molecular mechanisms by which H2S promotes cancer development, progression, dedifferentiation, and metastasis.

Abstract

Background and ObjectivesThe clinical course and outcome of the Guillain-Barré syndrome (GBS) are diverse and vary among regions. The modified Erasmus GBS Outcome Score (mEGOS), developed with data from Dutch patients, is a clinical model that predicts the risk of walking inability in patients with GBS. The study objective was to validate the mEGOS in the International GBS Outcome Study (IGOS) cohort and to improve its performance and region specificity.MethodsWe used prospective data from the first 1,500 patients included in IGOS, aged ≥6 years and unable to walk independently. We evaluated whether the mEGOS at entry and week 1 could predict the inability to walk unaided at 4 and 26 weeks in the full cohort and in regional subgroups, using 2 measures for model performance: (1) discrimination: area under the receiver operating characteristic curve (AUC) and (2) calibration: observed vs predicted probability of being unable to walk independently. To improve the model predictions, we recalibrated the model containing the overall mEGOS score, without changing the individual predictive factors. Finally, we assessed the predictive ability of the individual factors.ResultsFor validation of mEGOS at entry, 809 patients were eligible (Europe/North America [n = 677], Asia [n = 76], other [n = 56]), and 671 for validation of mEGOS at week 1 (Europe/North America [n = 563], Asia [n = 65], other [n = 43]). AUC values were >0.7 in all regional subgroups. In the Europe/North America subgroup, observed outcomes were worse than predicted; in Asia, observed outcomes were better than predicted. Recalibration improved model accuracy and enabled the development of a region-specific version for Europe/North America (mEGOS-Eu/NA). Similar to the original mEGOS, severe limb weakness and higher age were the predominant predictors of poor outcome in the IGOS cohort.DiscussionmEGOS is a validated tool to predict the inability to walk unaided at 4 and 26 weeks in patients with GBS, also in countries outside the Netherlands. We developed a region-specific version of mEGOS for patients from Europe/North America.Classification of EvidenceThis study provides Class II evidence that the mEGOS accurately predicts the inability to walk unaided at 4 and 26 weeks in patients with GBS.Trial Registration InformationNCT01582763.

Abstract

Background: Microvascular obstruction (MVO) predicts short- and longer-term outcomes following primary percutaneous coronary intervention (PPCI) treatment of ST-elevation myocardial infarction (STEMI). The evidence base supporting the role of adenosine and sodium nitroprusside (SNP), the most evaluated adjunctive therapies aimed at attenuating MVO and infarct size, remains weak as the trials involved have had variable end points and used differing drug doses and modes of delivery. Objective: To determine whether intracoronary administration of adenosine or SNP following thrombus aspiration reduces infarct size and/or MVO measured by cardiac magnetic resonance (CMR) imaging in patients undergoing PPCI within 6 hours of onset of STEMI. Design: Multicentre, prospective, parallel, randomised controlled and open-label trial with blinded end point analysis. Setting: Four high-volume UK PPCI centres. Participants: Patients with STEMI undergoing PPCI with Thrombolysis in Myocardial Infarction (TIMI) flow grade 0/1 in the infarct-related artery and no significant bystander coronary artery disease on angiography. Interventions: Participants were anticoagulated with bivalirudin and allocated by an automated 24-hour telephone randomisation service to one of three groups: (1) standard PPCI (control), (2) PPCI with adjunctive adenosine 1–2 mg or (3) PPCI with adjunctive SNP 250 µg. The study drugs were delivered intracoronary immediately following thrombus aspiration and again following successful stenting. Main outcome measures: The primary outcome was infarct size (% total left ventricular end-diastolic mass; %LVM) measured by CMR imaging undertaken 48–96 hours post PPCI. Secondary outcome measures included MVO (hypoenhancement within the infarct core) on CMR imaging, electrocardiographic and angiographic markers of microvascular perfusion and major adverse cardiac events (MACEs) during a median of 6 months’ follow-up. The study aimed to recruit 240 patients (powered at 80% to detect a 5% absolute reduction in infarct size). Results: The trial completed recruitment in April 2014 having randomised 247 patients (standard PPCI group, n = 86; PPCI + adenosine group, n = 82; PPCI + SNP group, n = 79). In total, 79% of participants were male and the mean ± standard deviation age of participants was 59.3 ± 12.3 years. CMR imaging was completed in 197 (80%) patients (standard PPCI, n = 65; PPCI + adenosine, n = 63; PPCI + SNP, n = 69) for the primary outcome. There was no significant difference in infarct size [%LVM, median, interquartile range (IQR)] between the adenosine group (10.1, 4.7–16.2), the SNP group (10.0, 4.2–15.8) and the control group (8.3, 1.9–14.0) (p = 0.062 and p = 0.160 vs. control, respectively). MVO (%LVM, median, IQR) was similar across the groups [1.0, 0.0–3.7 (p = 0.205) and 0.6, 0.0–2.4 (p = 0.244) for adenosine and SNP, respectively, vs. 0.3, 0.0–2.8 for the control]. Using per-protocol analysis, infarct size (%LVM) was increased in adenosine-treated patients compared with control patients (12.0 vs. 8.3; p = 0.031). Increased left ventricular volume and reduced left ventricular ejection fraction were also observed in the adenosine arm. There was a significant increase in MACEs in patients undergoing adenosine-facilitated PPCI compared with control patients, driven by heart failure, at 30 days [hazard ratio (HR) 5.39, 95% confidence interval (CI) 1.18 to 24.60; p = 0.04] and 6 months (HR 6.53, 95% CI 1.46 to 29.2; p = 0.01) post randomisation. Conclusions: High-dose intracoronary adenosine and SNP during PPCI did not reduce infarct size or MVO measured by CMR imaging. Furthermore, adenosine may adversely affect mid-term clinical outcome and should not be used during PPCI to prevent reperfusion injury. Trial registration: ClinicalTrials.gov NCT01747174 and EudraCT 2010–023211–34. Funding: This project was funded by the Efficacy and Mechanism Evaluation (EME) programme, a MRC and NIHR partnership.

72. Integrated environment-smart agricultural practices: A strategy towards climate-resilient agriculture

Author

Islam, Z., Sabiha, N.E., Salim, Ruhul, Islam, Z., Sabiha, N.E., and Salim, Ruhul

Abstract

This article proposes an integrated farming approach, namely environment-smart agriculture (ESA) that determines the climate-resilience potential of a farm. A composite index is formulated including various environment-smart agricultural practices (IEP) that focus on the five most affected target areas of farm environment and climate. The IEP is then validated by analysing the on-farm environmental impact and farmers’ behaviours in the underlying theory of planned behaviour (TPB) framework. The TPB components, attitude and subjective norm are defined by the index of benefits from the ESA, and the index of experienced climate change conditions respectively, while perceived control corresponds to the index of constraints in adopting ESA and farm-specific agro-economic and socio-economic attributes. The empirical testing employed a structural equations model (SEM) to estimate the proposed IEP on a sample of 103 farms in two north-western districts of Bangladesh. Results demonstrate that the adoption of integrated ESA practices mitigates post-harvest environmental problems and helps cope with existing climate change conditions. Therefore, farm-level investment in ESA practices, i.e., the use of corrective, preventive, and local standard measures in an integrated way will contribute to the climate-resilience potential of a farm.

Abstract

Background and objectives: The clinical course and outcome of the Guillain-Barré syndrome (GBS) are diverse and vary among regions. The modified Erasmus GBS Outcome Score (mEGOS), developed with data from Dutch patients, is a clinical model that predicts the risk of walking inability in patients with GBS. The study objective was to validate the mEGOS in the International GBS Outcome Study (IGOS) cohort and to improve its performance and region specificity. Methods: We used prospective data from the first 1,500 patients included in IGOS, aged ≥6 years and unable to walk independently. We evaluated whether the mEGOS at entry and week 1 could predict the inability to walk unaided at 4 and 26 weeks in the full cohort and in regional subgroups, using 2 measures for model performance: (1) discrimination: area under the receiver operating characteristic curve (AUC) and (2) calibration: observed vs predicted probability of being unable to walk independently. To improve the model predictions, we recalibrated the model containing the overall mEGOS score, without changing the individual predictive factors. Finally, we assessed the predictive ability of the individual factors. Results: For validation of mEGOS at entry, 809 patients were eligible (Europe/North America [n = 677], Asia [n = 76], other [n = 56]), and 671 for validation of mEGOS at week 1 (Europe/North America [n = 563], Asia [n = 65], other [n = 43]). AUC values were >0.7 in all regional subgroups. In the Europe/North America subgroup, observed outcomes were worse than predicted; in Asia, observed outcomes were better than predicted. Recalibration improved model accuracy and enabled the development of a region-specific version for Europe/North America (mEGOS-Eu/NA). Similar to the original mEGOS, severe limb weakness and higher age were the predominant predictors of poor outcome in the IGOS cohort. Discussion: mEGOS is a validated tool to predict the inability to walk unaided at 4 and 26 weeks in patients with

Samir Saba,* Haider Mehdi,* William Barrington, Fardeen Mehdi, Zahid Islam, Barry LondonCardiovascular Institute of the University of Pittsburgh Medical Center, Pittsburgh, PA, USA*These authors contributed equally to this workBackground: Improved clinical and echocardiographic parameters have been documented with biventricular (BIV) pacing in patients after myocardial infarction (MI). We investigated the changes in gene expression in cardiac tissue with BIV pacing, using a rabbit model of MI.Method: New Zealand White rabbits were divided into four groups: sham-operated controls, MI with no pacing, MI with right ventricle (RV) pacing (MI + RV), and MI with BIV pacing (MI + BIV). Pacing was initiated 1–2 weeks after the coronary ligation. At 5 weeks, the hearts were excised. The tissue extracted from the left ventricle (LV) and RV underwent analysis for protein and messenger ribonucleic acid (mRNA) levels.Results: The ether-a-go-go-related gene (ERG) protein levels recovered from the base of the LV away from the MI area were two- to threefold lower in the MI and the MI + RV compared with the MI + BIV groups (P = 0.07). The ERG protein levels were similar between the MI + BIV and the control groups. However, the RNA levels were comparable between the four study groups, suggesting that a posttranscriptional mechanism accounted for the difference in protein levels.Conclusion: In this rabbit model of MI, we demonstrated a recovery in ERG protein levels with BIV pacing, after MI. This recovery may underlie some of the benefits seen with BIV pacing in ischemic cardiomyopathy.Keywords: heart failure, biventricular pacing, cardiac reverse remodeling, ether-a-go-go-related gene

Abstract

Bioethanol is one of the most important biofuel due to its positive impact on the environment. However, its economic production is dependent primarily on the raw materials used and the fermentation potentiality of the microorganisms. Therefore, this study was aimed to screen for thermotolerant Saccharomyces cerevisiae yeast isolates from common fruits of Bangladesh and produce bioethanol from decaying fruit wastes. Nine different fruits were collected and subjected for anaerobic growth. Colonies similar to S. cerevisiae yeast were isolated based on cultural (colony shape, size, color, elevation, surface edge, consistency), morphological (bud, cell shape) and biochemical characteristics (carbohydrate fermentation). Molecular confirmation was done using S. cerevisiae RSP5-C allele specific primer. Six isolates were confirmed as S. cerevisiae based on cultural, morphological, biochemical and molecular characteristics studied. From the four isolates that showed the growth capacity at a higher (41 °C) temperature than optimum (30 0C), SC-Gr, the isolate from grape, showed the most active growth at 41 °C and used to produce bioethanol from decaying fruits like banana, papaya, apple and grape. The significantly highest amount of bioethanol concentration (7.92 %) was obtained from the grape waste at 37 °C, at pH 5 after 48 hrs of the fermentation period and the lowest amount of bioethanol (2.37 %) was obtained from decaying banana at 45 °C and pH 5.0 after 72 hrs of fermentation period. This study suggested that decaying fruits could be better utilized in the industry of renewable fuel energy using thermotolerant yeast isolate from grapes. [ABSTRACT FROM AUTHOR]

Abstract

Canned fish portions had laid down limits of pH that should not be more than 6.7; TVN should not be more than 40 mg/l00g (EOS, 2005) .This study was conducted on 105 samples of imported canned fish for recording the chemical evaluation of these samples. The chemical examination declared that the mean values of TBA and TVN were 14.8±1.4 and 23±1.5 mg% for canned mackerel, 4.8±0.4 and 23.2±0.6 mg% for canned sardine and 1.9±0.1 and 18.6±2.5 mg% for canned tuna, respectively. Significant differences (P≥0.05) appeared between the examined samples of canned mackerel, sardine and tuna as a result of TBA and TVN values. current study classified the presence of some unacceptable imported canned fish for human consumption .that indicate the importance of chemical evaluation of canned fish. recommended future study must be applied chemical and molecular methods to compare efficiency of current chemical method to control this problems in future and save people health .

Abstract

Background/aim Ethylmalonic encephalopathy 1 protein (ETHE1) plays an important role in sulfide catabolism and polysulfide formation. As sulfides and polysulfides have recently been identified as playing important roles in cancer, we hypothesized that ETHE1 expression would be increased in colon cancer. Materials and methods We used tissue microarray analysis to compare ETHE1 expression in benign colonic epithelium compared to colonic adenocarcinoma. In total, 26 benign colonic epithelial samples were compared to 122 cases of colonic adenocarcinomas. Results Compared to benign colonic epithelium, ETHE1 expression was significantly increased (~two-fold) in colonic adenocarcinoma. Additionally, this expression increased with increasing colon cancer tumor grades. Conclusion ETHE1 expression is increased in colon cancer compared to benign colonic epithelium. These data, combined with previous studies, suggest that ETHE1 may contribute to colon carcinogenesis by promoting tumor cell bioenergetics and polysulfide formation.

Abstract

ObjectiveTo define the current treatment practice of Guillain-Barré syndrome (GBS).MethodsThe study was based on prospective observational data from the first 1,300 patients included in the International GBS Outcome Study. We described the treatment practice of GBS in general, and for (1) severe forms (unable to walk independently), (2) no recovery after initial treatment, (3) treatment-related fluctuations, (4) mild forms (able to walk independently), and (5) variant forms including Miller Fisher syndrome, taking patient characteristics and hospital type into account.ResultsWe excluded 88 (7%) patients because of missing data, protocol violation, or alternative diagnosis. Patients from Bangladesh (n = 189, 15%) were described separately because 83% were not treated. IV immunoglobulin (IVIg), plasma exchange (PE), or other immunotherapy was provided in 941 (92%) of the remaining 1,023 patients, including patients with severe GBS (724/743, 97%), mild GBS (126/168, 75%), Miller Fisher syndrome (53/70, 76%), and other variants (33/40, 83%). Of 235 (32%) patients who did not improve after their initial treatment, 82 (35%) received a second immune modulatory treatment. A treatment-related fluctuation was observed in 53 (5%) of 1,023 patients, of whom 36 (68%) were re-treated with IVIg or PE.ConclusionsIn current practice, patients with mild and variant forms of GBS, or with treatment-related fluctuations and treatment failures, are frequently treated, even in absence of trial data to support this choice. The variability in treatment practice can be explained in part by the lack of evidence and guidelines for effective treatment in these situations.

Abstract

ObjectiveTo compare disease course in patients with Guillain-Barré syndrome (GBS) with a poor prognosis who were treated with one or with two intravenous immunoglobulin (IVIg) courses.MethodsFrom the International GBS Outcome Study, we selected patients whose modified Erasmus GBS Outcome Score at week 1 predicted a poor prognosis. We compared those treated with one IVIg course to those treated with two IVIg courses. The primary endpoint, the GBS disability scale at 4 weeks, was assessed with multivariable ordinal regression.ResultsOf 237 eligible patients, 199 patients received a single IVIg course. Twenty patients received an ‘early’ second IVIg course (1–2 weeks after start of the first IVIg course) and 18 patients a ‘late’ second IVIg course (2–4 weeks after start of IVIg). At baseline and 1 week, those receiving two IVIg courses were more disabled than those receiving one course. Compared with the one course group, the adjusted OR for a better GBS disability score at 4 weeks was 0.70 (95%CI 0.16 to 3.04) for the early group and 0.66 (95%CI 0.18 to 2.50) for the late group. The secondary endpoints were not in favour of a second IVIg course.ConclusionsThis observational study did not show better outcomes after a second IVIg course in GBS with poor prognosis. The study was limited by small numbers and baseline imbalances. Lack of improvement was likely an incentive to start a second IVIg course. A prospective randomised trial is needed to evaluate whether a second IVIg course improves outcome in GBS.

Abstract

Guillain-Barré syndrome (GBS) is a post-infection sequela of Campylobacter jejuni-induced enteritis. Clustered regularly interspaced short palindromic repeats and associated genes (CRISPR-Cas) confers adaptive immunity and plays role in virulence in many bacteria. We investigated C. jejuni CRISPR type (CT) to explore association of CRISPR-Cas with risk of developing GBS. We analysed CRISPR-Cas in C. jejuni isolated from 30 patients with GBS, 60 patients with enteritis and 52 healthy controls from Bangladesh. CRISPR types were determined by PCR followed by CRISPR array sequencing. Statistical and genomic analyses were performed using SPSS and multiple web-based software respectively. We found preserved CRISPR array was significantly more frequent in GBS-related strains than healthy control-related strains (P = 0.02, OR = 2.95). Increased CRISPR array length was significantly associated with GBS compared to healthy control- (P = 0.003, AUC = 0.7) and enteritis-related strains (P = 0.02, AUC = 0.65). We reported 38 new CT found among 70 CRISPR-preserving strains. CT of GBS-related strains were unique from enteritis- and healthy control-related strains. Eighty spacers, including 20 novel spacers, were identified among the CRISPR-preserving strains. CRISPR typing had more discriminatory power than PCR-based subtyping in enteritis- and healthy control-related strains. Further genomic analyses are warranted to elucidate role of the C. jejuni CRISPR array in GBS pathogenesis.

Abstract

Vehicular ad-hoc networks (VANETs) play an essential role in the development of the intelligent transportation system (ITS). VANET supports many types of applications that have strict time constraints. The communication and computational overheads are minimal for these computations and there are many security requirements that should be maintained. We propose an efficient message authentication system with a privacy preservation protocol. This protocol reduces the overall communication and computational overheads. The proposed protocol consists of three main phases: the group registration phase, send/receive messages phase, and the leave/join phase. For cryptography algorithms, we combined symmetric and asymmetric key algorithms. The symmetric key was generated and exchanged without using the Diffie–Hellman (DH) protocol. Furthermore, we used an efficient version of the RSA algorithm called CRT-RSA. The experimental results showed that the computational overhead in the registration phase was significantly reduced by 91.7%. The computational overhead for sending and receiving the non-safety message phase was reduced by 41.2% compared to other existed protocols. Moreover, our results showed that the time required to broadcast a safety and non-safety group message was below 100 ms and 150 ms, respectively. The average computational time of sending and receiving a one-to-one message was also calculated. The proposed protocol was also evaluated with respect to performance and security and was shown to be invulnerable to many security attacks.

Abstract

ObjectiveTo compare the disease course in patients with mild Guillain-Barré syndrome (GBS) who were treated with intravenous immunoglobulin (IVIg) or supportive care only.MethodsWe selected patients from the prospective observational International GBS Outcome Study (IGOS) who were able to walk independently at study entry (mild GBS), treated with one IVIg course or supportive care. The primary endpoint was the GBS disability score four weeks after study entry, assessed by multivariable ordinal regression analysis.ResultsOf 188 eligible patients, 148 (79%) were treated with IVIg and 40 (21%) with supportive care. The IVIg group was more disabled at baseline. IVIg treatment was not associated with lower GBS disability scores at 4 weeks (adjusted OR (aOR) 1.62, 95% CI 0.63 to 4.13). Nearly all secondary endpoints showed no benefit from IVIg, although the time to regain full muscle strength was shorter (28 vs 56 days, p=0.03) and reported pain at 26 weeks was lower (n=26/121, 22% vs n=12/30, 40%, p=0.04) in the IVIg treated patients. In the subanalysis with persistent mild GBS in the first 2 weeks, the aOR for a lower GBS disability score at 4 weeks was 2.32 (95% CI 0.76 to 7.13). At 1 year, 40% of all patients had residual symptoms.ConclusionIn patients with mild GBS, one course of IVIg did not improve the overall disease course. The certainty of this conclusion is limited by confounding factors, selection bias and wide confidence limits. Residual symptoms were often present after one year, indicating the need for better treatments in mild GBS.

Abstract

We evaluated the presence of influenza A(H5) virus environmental contamination in live bird markets (LBMs) in Dhaka, Bangladesh. By using Bernoulli generalized linear models and multinomial logistic regression models, we quantified LBM-level factors associated with market work zone-specific influenza A(H5) virus contamination patterns. Results showed higher environmental contamination in LBMs that have wholesale and retail operations compared with retail-only markets (relative risk 0.69, 95% 0.51-0.93; p = 0.012) and in March compared with January (relative risk 2.07, 95% CI 1.44-2.96; p<0.001). Influenza A(H5) environmental contamination remains a public health problem in most LBMs in Dhaka, which underscores the need to implement enhanced biosecurity interventions in LBMs in Bangladesh.

Abstract

Background: The most common subtypes of Guillain-Barré syndrome (GBS) are acute inflammatory demyelinating polyneuropathy (AIDP) and acute motor axonal neuropathy (AMAN). In the first days after the onset of weakness, standard nerve conduction studies (NCS) may not distinguish GBS subtypes. Reduced nerve excitability may be an early symptom of nerve dysfunction, which can be determined with the compound muscle action potential (CMAP) scan. The aim of this study was to explore whether early changes in motor nerve excitability in GBS patients are related to various subtypes. Methods: Prospective case–control study in 19 GBS patients from The Netherlands and 22 from Bangladesh. CMAP scans were performed within 2 days of hospital admission and NCS 7–14 days after onset of weakness. CMAP scans were also performed in age- and country-matched controls. Results: CMAP scan patterns of patients who were classified as AMAN were distinctly different compared to the CMAP scan patterns of the patients who were classified as AIDP. The most pronounced differences were found in the stimulus intensity parameters. Conclusions: CMAP scans made at hospital admission demonstrate several characteristics that can be used as an early indicator of GBS subtype.

Abstract

Guillain-Barré syndrome (GBS) is an acute polyradiculoneuropathy with a highly variable clinical presentation, course, and outcome. The factors that determine the clinical variation of GBS are poorly understood which complicates the care and treatment of individual patients. The protocol of the ongoing International GBS Outcome Study (IGOS), a prospective, observational, multicenter cohort study that aims to identify the clinical and biological determinants and predictors of disease onset, subtype, course and outcome of GBS is presented here. Patients fulfilling the diagnostic criteria for GBS, regardless of age, disease severity, variant forms, or treatment, can participate if included within 2 weeks after onset of weakness. Information about demography, preceding infections, clinical features, diagnostic findings, treatment, course, and outcome is collected. In addition, cerebrospinal fluid and serial blood samples for serum and DNA is collected at standard time points. The original aim was to include at least 1,000 patients with a follow-up of 1-3 years. Data are collected via a web-based data entry system and stored anonymously. IGOS started in May 2012 and by January 2017 included more than 1,400 participants from 143 active centers in 19 countries across 5 continents. The IGOS data/biobank is available for research projects conducted by expertise groups focusing on specific topics including epidemiology, diagnostic criteria, clinimetrics, electrophysiology, antecedent events, antibodies, genetics, prognostic modeling, treatment effects, and long-term outcome of GBS. The IGOS will help to standardize the international collection of data and biosamples for future research of GBS.

Abstract

Problem statement: The design and implementation of a sinusoidal Pulse-Width Modulation (PWM) generator for a single-phase hybrid power filter is presented. Approach: The PWM was developed in an Altera[R] Flex 10 K Field Programmable Gate Array (FPGA) and the modulation index was selected by calculating the DC bus voltage of the active filter through a digital controller, by Proportional-Integral-Derivative (PID) technique. Results: Experiment results showed the proposed active power filter topology to be capable of compensating the load current and the voltage harmonic, up to IEC limit. Conclusion: The implemented PWM generator using an FPGA required less memory usage while providing flexible PWM patterns whether same phase, lagging, or leading, the reference voltage signal. Key words: Active power filter, PWM, FPGA, power quality, INTRODUCTION Pulse width modulation techniques have been intensively researched in the past few years. Methods, of various concept and performance, have been developed and described. Their design implementation depends on [...]
