OMMA enables population-scale analysis of complex genomic features and phylogenomic relationships from nanochannel-based optical maps.
BackgroundOptical mapping is an emerging technology that complements sequencing-based methods in genome analysis. It is widely used in improving genome assemblies and detecting structural variations by providing information over much longer (up to 1 Mb) reads. Current standards in optical mapping analysis involve assembling optical maps into contigs and aligning them to a reference, which is limited to pairwise comparison and becomes bias-prone when analyzing multiple samples.FindingsWe present a new method, OMMA, that extends optical mapping to the study of complex genomic features by simultaneously interrogating optical maps across many samples in a reference-independent manner. OMMA captures and characterizes complex genomic features, e.g., multiple haplotypes, copy number variations, and subtelomeric structures when applied to 154 human samples across the 26 populations sequenced in the 1000 Genomes Project. For small genomes such as pathogenic bacteria, OMMA accurately reconstructs the phylogenomic relationships and identifies functional elements across 21 Acinetobacter baumannii strains.ConclusionsWith the increasing data throughput of optical mapping system, the use of this technology in comparative genome analysis across many samples will become feasible. OMMA is a timely solution that can address such computational need. The OMMA software is available at https://github.com/TF-Chan-Lab/OMTools
A Thiazole Orange Derivative Targeting the Bacterial Protein FtsZ Shows Potent Antibacterial Activity.
The prevalence of multidrug resistance among clinically significant bacteria calls for the urgent development of new antibiotics with novel mechanisms of action. In this study, a new small molecule exhibiting excellent inhibition of bacterial cell division with potent antibacterial activity was discovered through cell-based screening. The compound exhibits a broad spectrum of bactericidal activity, including the methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus and NDM-1 Escherichia coli. The in vitro and in vivo results suggested that this compound disrupts the dynamic assembly of FtsZ protein and Z-ring formation through stimulating FtsZ polymerization. Moreover, this compound exhibits no activity on mammalian tubulin polymerization and shows low cytotoxicity on mammalian cells. Taken together, these findings could provide a new chemotype for development of antibacterials with FtsZ as the target
Nucleocapsid Protein as Early Diagnostic Marker for SARS
Serum samples from 317 patients with patients with severe acute respiratory syndrome (SARS) were tested for the nucleocapsid (N) protein of SARS-associated coronavirus, with sensitivities of 94% and 78% for the first 5 days and 6–10 days after onset, respectively. The specificity was 99.9%. N protein can be used as an early diagnostic maker for SARS

Nurses' knowledge of universal health coverage for inclusive and sustainable elderly care services
Objectives: to explore nurses' knowledge of universal health coverage (UHC) for inclusive and sustainable development of elderly care services. Method: this was a cross-sectional survey. A convenience sample of 326 currently practicing enrolled nurses (EN) or registered nurses (RN) was recruited. Respondents completed a questionnaire which was based on the implementation strategies advocated by the WHO Global Forum for Governmental Chief Nursing Officers and Midwives (GCNOMs). Questions covered the government initiative, healthcare financing policy, human resources policy, and the respondents' perception of importance and contribution of nurses in achieving UHC in elderly care services. Results: the knowledge of nurses about UHC in elderly care services was fairly satisfactory. Nurses in both clinical practice and management perceived themselves as having more contribution and importance than those in education. They were relatively indifferent to healthcare policy and politics. Conclusion: the survey uncovered a considerable knowledge gap in nurses' knowledge of UHC in elderly care services, and shed light on the need for nurses to be more attuned to healthcare policy. The educational curriculum for nurses should be strengthened to include studies in public policy and advocacy. Nurses can make a difference through their participation in the development and implementation of UHC in healthcare services.Objetivos: explorar o conhecimento dos enfermeiros sobre a cobertura universal de saúde (CUS) para o desenvolvimento inclusivo e sustentável de serviços de saúde a idosos. Método: estudo transversal. Foi recrutada uma amostra de conveniência de 326 enrolled nurses (EN) ou registered nurses (RN). Os entrevistados responderam a um questionário com base nas estratégias de implementação preconizadas pelo Fórum Global da OMS para Governmental Chief Nursing Officers and Midwives (GCNOMs). As perguntas abordavam iniciativas do governo, políticas de financiamento da saúde, políticas de recursos humanos e percepção dos entrevistados sobre a importância e contribuição do enfermeiro no alcance da CUS em serviços de cuidados a idosos. Resultado: o conhecimento de enfermeiros sobre a CUS em serviço de atenção ao idoso foi razoavelmente satisfatório. Enfermeiros tanto da prática clínica como da gestão perceberam-se contribuindo mais e tendo mais importância do que aqueles que trabalham na educação. Eles eram relativamente indiferentes à política de saúde e à política. Conclusão: a pesquisa revelou uma lacuna de conhecimento considerável no conhecimento da CUS pelos enfermeiros nos serviços de cuidados a idosos e evidenciou a necessidade de enfermeiros terem mais sintonia com a política de saúde. O currículo de formação para preparar os enfermeiros deve ser reforçado para incluir estudos em política pública e advocacia. Os enfermeiros podem fazer a diferença por meio de sua participação no desenvolvimento e implementação da CUS nos serviços de saúde.Objetivos: explorar los conocimientos que tienen las enfermeras sobre la cobertura universal de salud (CUS) para el desarrollo inclusivo y sostenible de servicios para el cuidado de adultos mayores. Método: se utilizó una encuesta transversal. Se formó una muestra de conveniencia de 326 enrolled nurses (EN) o registered nurses (RN) que actualmente estuvieran ejerciendo. Los encuestados respondieron a un cuestionario basado en las estrategias de implementación apoyadas por el WHO Global Forum for Government Chief Nursing and Midwifery Officers (WGFGCNO). Las preguntas abarcaban la iniciativa del gobierno, políticas de financiamiento de la salud, las políticas de recursos humanos y la percepción de los encuestados sobre la importancia y la contribución de las enfermeras en el logro de la CUS en los servicios de cuidado para adultos mayores. Resultados: el conocimiento de las enfermeras sobre CUS en el servicio de cuidado para los adultos mayores fue bastante satisfactorio. Tanto las enfermeras de práctica clínica y como las de gestión perciben tener un mayor aporte e importancia que las de que están en educación. Tenían un punto de vista relativamente indiferente a la política sanitaria y la política. Conclusión: la encuesta descubrió una considerable brecha en el conocimiento de las enfermeras sobre CUS en los servicios de cuidado para adultos mayores y puso de manifiesto la necesidad de que las enfermeras estén más en sintonía con la política sanitaria. El plan de estudios para la preparación de las enfermeras debe fortalecerse para incluir estudios en las políticas públicas y promoción. Las enfermeras pueden hacer una diferencia a través de su participación en el desarrollo e implementación de CUS en los servicios de salud

An update on genomic-guided therapies for pediatric solid tumors
YesCurrently, out of the 82 US FDA-approved targeted therapies for adult cancer treatments, only three are approved for use in children irrespective of their genomic status. Apart from leukemia, only a handful of genomic-based trials involving children with solid tumors are ongoing. Emerging genomic data for pediatric solid tumors may facilitate the development of precision medicine in pediatric patients. Here, we provide an up-to-date review of all reported genomic aberrations in the eight most common pediatric solid tumors with whole-exome sequencing or whole-genome sequencing data (from cBioPortal database, Pediatric Cancer Genome Project, Therapeutically Applicable Research to Generate Effective Treatments) and additional non-whole-exome sequencing studies. Potential druggable events are highlighted and discussed so as to facilitate preclinical and clinical research in this area.Seed Grant of Strategic Research Theme for Cancer, The University of Hong Kong of AKSC.
