Abstract Background Previously, we presented the short-term outcomes of surgeon-tailored mesh in patients with SUI undergoing TOT. In this report, we aim to highlight the two-year outcomes of surgeon tailored mesh in terms of subjective and objective cure rates, as well as late complications. Methods We performed a randomized, open-label comparative trial that recruited women with SUI who were scheduled to undergo TOT. Eligible patients were randomly allocated in a 1:1 ratio to receive traditional TOT mesh or surgeon-tailored polyethylene mesh. All patients were followed up for two years. Results At the end of the follow-up, there were 13 women in the traditional TOT mesh group and 14 patients in the surgeon-tailored polyethylene mesh group. Concerning the primary outcome of the present study, the cure rate was 100% in the surgeon-tailored polyethylene mesh (n = 14) and 92.9% in the traditional TOT mesh group (p = 0.39). One woman reported improved symptoms in the traditional TOT mesh group. There were no reported failures in both groups. Concerning safety, the incidence of de novo urgency was 0% in the surgeon-tailored polyethylene mesh group, compared to 7.1% in the traditional TOT mesh group (p = 0.34). None of the women in both groups reported mesh erosions, dyspareunia, or need for reoperation. Conclusion Surgeon-tailored mesh for patients undergoing TOT is a cost-effective technique, which has comparable long-term outcomes, in terms of cure rate and complications, to the traditional costly meshes. Larger multicentre studies should confirm our results.

Genotype By Sequencing

AbstractGenotype-by-sequencing (GBS) is a widely used cost-effective technique to obtain large numbers of genetic markers from populations. Although a standard reference-based pipeline can be followed to analyze these reads, a reference genome is still not available for a large number of species. Hence, several research groups require reference-free approaches to generate the genetic variability information that can be obtained from a GBS experiment. Unfortunately, tools to perform de-novo analysis of GBS reads are scarce and some of the existing solutions are difficult to operate under different settings generated by the existing GBS protocols. In this manuscript we describe a novel algorithm to perform reference-free variants detection and genotyping from GBS reads. Non-exact searches on a dynamic hash table of consensus sequences allow to perform efficient read clustering and sorting. This algorithm was integrated in the Next Generation Sequencing Experience Platform (NGSEP) to integrate the state-of- the-art variants detector already implemented in this tool. We performed benchmark experiments with three different real populations of plants and animals with different structures and ploidies, and sequenced with different GBS protocols at different read depths. These experiments show that NGSEP has comparable and in some cases better accuracy and always better computational efficiency compared to existing solutions. We expect that this new development will be useful for several research groups conducting population genetic studies in a wide variety of species.

The Brain

Aggregation of amyloid beeta 1-42 (Aβ<sub>42</sub>) peptide causes the formation of clustered deposits knows as amyloid plaques in the brain which leads to neuronal dysfunction and memory loss and associated with many neurological disorders including Alzheimer’s and Parkinson’s. Aβ<sub>42</sub> has core structural motif with phenylalanine at the 19 and 20 positions. The diphenylalanine (FF) residue plays a crucial role in the formation of amyloid fibers and serves as model peptide for studying Aβ<sub>42 </sub>aggregation. FF self-assembles to well-ordered tubular morphology via aromatic pi-pi stackings. Our studies, suggest that the aromatic rings present in the anti-amyloidogenic compounds may interact with the pi-pi stacking interactions present in the FF. Even the compounds which do not have aromatic rings, like cyclodextrin and cucurbituril show anti-amyloid property due to the binding of aromatic ring inside the guest cavity. Hence, our studies also suggest that compounds which may have a functional moiety capable of interacting with the aromatic stacking interactions might be tested for their anti-amyloidogenic properties. Further, in this manuscript, we have proposed two novel nanoparticle based assays for the rapid screening of amyloid inhibitors. In the first assay, interaction between biotin-tagged FF peptide and the streptavidin labelled gold nanoparticles (s-AuNPs) were used. In another assay, thiol-Au interactions were used to develop an assay for detection of amyloid inhibitors. It is envisaged that the proposed analytical method will provide a simple, facile and cost effective technique for the screening of amyloid inhibitors and may be of immense practical implications to find the therapeutic remedies for the diseases associated with the protein aggregation.

Knowledge Attitude And Practice

Currently, 314 million people in the world are Prediabetes, and it is predicted that around 500 million would be burdened by the year 2025. Continuing education of diabetes and its complications is crucial, but it should be accompanied with regular assessment of Knowledge Attitude and Practice (KAP) among the high-risk population. That would play a cost-effective role in prevention and control of the disease.This study was carried out to assess the Knowledge, Attitude and Practice among the newly diagnosed Prediabetes screened over selected districts of South India.This study was conducted through prediabetes screening camps over districts of Calicut, Wayanad and Malappuram in Kerala and The Nilgiris district in Tamilnadu from September 2017 to October 2019. A questionnaire survey was done as a part of a prospective open-label interventional study with 308 prediabetes individuals. Baseline characteristics of the participants were obtained, and their knowledge, attitude and practice regarding Prediabetes were assessed. The finding of the present study revealed 90% of the respondents had poor knowledge, 9% had average knowledge, and only 1% had good knowledge of Prediabetes. In the attitude assessment, only 1.9% had a strongly positive attitude, 14% had a positive attitude, 54% had neutral attitude while 17% had a negative attitude and 13% had a strongly negative attitude. Regarding healthy lifestyle practices, 35.4% had a deplorable practice that scored below 6. Around half of the population, 52.3% had poor practice, 12% had proper training, while only 0.3% had a perfect practice.Knowledge and practice regarding lifestyle modifications among prediabetes participants were found to be reduced.

:As a long-term degenerative disorder of the central nervous system that mostly affects older people, Parkinson’s disease is a growing health threat to our ever-aging population. Despite remarkable advances in our understanding of this disease, all therapeutics currently available only act to improve symptoms but cannot stop the disease progression. Therefore, it is essential that more effective drug discovery methods and approaches are developed, validated, and used for the discovery of disease-modifying treatments for Parkinson’s disease. Drug repurposing, also known as drug repositioning, or the process of finding new uses for existing or abandoned pharmaceuticals, has been recognized as a cost-effective and timeefficient way to develop new drugs, being equally promising as de novo drug discovery in the field of neurodegeneration and, more specifically for Parkinson’s disease. The availability of several established libraries of clinical drugs and fast evolvement in disease biology, genomics and bioinformatics has stimulated the momentums of both in silico and activity-based drug repurposing. With the successful clinical introduction of several repurposed drugs for Parkinson’s disease, drug repurposing has now become a robust alternative approach to the discovery and development of novel drugs for this disease. In this review, recent advances in drug repurposing for Parkinson’s disease will be discussed.

Template Dna

<i>Ditylenchus dipsaci</i>, the stem nematode, is a migratory endoparasite of over 500 species of angiosperms. The main method of <i>D. dipsaci</i> control is crop rotation, but the presence of morphologically indistinguishable host races with different host preferences makes rotation generally ineffective. Therefore, a sensitive, rapid, reliable, as well as cost effective technique is needed for identification of <i>D. dipsaci</i> in biological samples. This study describes the development of species-specific pairs of PCR oligonucleotides for detection and identification of the <i>D. dipsaci</i> stem nematode in various plant hosts. Designed DIT-2 primer pair specifically amplified a fragment of 325 bp, while DIT-5 primer pair always produced a fragment of 245 bp in all <i>D. dipsaci</i> isolates. Two developed SCAR primer pairs were further tested using template DNA extracted from a collection of twelve healthy plant hosts; no amplification was however observed. The developed PCR protocol has proved to be quite sensitive and able to specifically detect <i>D. dipsaci</i> in artificially infested plant tissues.

Arteriovenous fistula (AVF) complications are classified based on fistula outcomes. This review aims to update colour Doppler (CD) and pulse wave Doppler (PWD) roles in managing early and late complications of the native and prosthetic AVF. Vascular access (VA) failure occurs because inflow or outflow stenosis activates Wirchow’s triad inducing thrombosis. Therefore, the diagnosis of the tributary artery and outgoing vein stenosis will be the first topic considered. Post-implantation complications occur from the inability to achieve AVF maturation and dialysis suitability due to inflow/outflow stenosis. Late stenosis is usually a sequence of early defects repaired to maintain patency. Less frequently, in the mature AVF or graft, complications are acquired ‘de novo’. They derive either from incorrect management of vascular access (haematoma, pseudoaneurysm, prosthesis infection) or wall pathologies (aneurysm, myxoid valve degeneration, kinking, coiling, abnormal dilation from defects of elastic structures). High-resolution transducers (10–20 MHz) allow the characterization of the wall damage, haemodynamic dysfunctions, early and late complications even if phlebography remains the gold standard for the diagnosis for its sensitivity and specificity.

We revised 16 patients submitted to epilepsy surgery using a new method of digital, real-time, portable electrocorticography. Patients were operated upon over a period of 28 months. There were no complications. The exam was useful in 13 cases. The low installation and operational costs, the reliability and simplicity of the method, indicate it may be useful for defining the epileptogenic regions in a variety of circumnstances, including surgery for tumors, vascular malformations, and other cortical lesions associated with seizure disorders.
