Local Health Departments’ Level of Engagement in Population Mental Health Promotion

Background: Mental health conditions are highly prevalent in the U.S. and are associated with physical health problems. Federal initiatives recognize mental health as a public health priority, and local health departments (LHDs) have been identified as partners to promote population mental health. Little is known, however, about the extent to which LHDs address mental health or how LHD officials perceive mental health as a public health concern. Purpose: To describe the cumulative level of LHDs’ engagement in activities to address population mental health and explore how LHD officials perceive their roles in promoting it. Methods: Module 2 of the 2013 National Profile of Local Health Departments Study (N=505) was used to develop a cumulative measure of LHD engagement in mental health activities. Univariate and bivariate analyses were performed to describe LHDs’ level of mental health activity and identify associated LHD characteristics. Semi-structured in-depth interviews were conducted with 30 LHD officials, audio-recorded, transcribed, and analyzed using thematic content analysis. Results: Over half (55.8%) of LHDs performed ≥1 mental health activities, and 21.2% performed ≥4. LHDs that provided primary care services were most engaged in mental health activities, with 30.4% performing ≥4 and 18.2% performing ≥6. LHD officials perceived mental health as a public health issue and felt community pressure to address it, but encountered barriers related to resources and organizational boundaries. Implications: LHDs might benefit from quality improvement and information sharing resources focused on population mental health promotion. Research should examine LHDs relationships with behavioral health departments and roles within broader social service systems

Gas emissions, minerals, and tars associated with three coal fires, Powder River Basin, USA.

Ground-based surveys of three coal fires and airborne surveys of two of the fires were conducted near Sheridan, Wyoming. The fires occur in natural outcrops and in abandoned mines, all containing Paleocene-age subbituminous coals. Diffuse (carbon dioxide (CO(2)) only) and vent (CO(2), carbon monoxide (CO), methane, hydrogen sulfide (H(2)S), and elemental mercury) emission estimates were made for each of the fires. Additionally, gas samples were collected for volatile organic compound (VOC) analysis and showed a large range in variation between vents. The fires produce locally dangerous levels of CO, CO(2), H(2)S, and benzene, among other gases. At one fire in an abandoned coal mine, trends in gas and tar composition followed a change in topography. Total CO(2) fluxes for the fires from airborne, ground-based, and rate of fire advancement estimates ranged from 0.9 to 780mg/s/m(2) and are comparable to other coal fires worldwide. Samples of tar and coal-fire minerals collected from the mouth of vents provided insight into the behavior and formation of the coal fires

Interactions between interfaces dictate stimuli-responsive emulsion behaviour

Stimuli-responsive emulsions offer a dual advantage, combining long-term storage with controlled release triggered by external cues such as pH or temperature changes. This study establishes that thermo-responsive emulsion behaviour is primarily determined by interactions between, rather than within, interfaces. Consequently, the stability of these emulsions is intricately tied to the nature of the stabilizing microgel particles - whether they are more polymeric or colloidal, and the morphology they assume at the liquid interface. The colloidal properties of the microgels provide the foundation for the long-term stability of Pickering emulsions. However, limited deformability can lead to non-responsive emulsions. Conversely, the polymeric properties of the microgels enable them to spread and flatten at the liquid interface, enabling stimuli-responsive behaviour. Furthermore, microgels shared between two emulsion droplets in flocculated emulsions facilitate stimuli-responsiveness, regardless of their internal architecture. This underscores the pivotal role of microgel morphology and the forces they exert on liquid interfaces in the control and design of stimuli-responsive emulsions and interfaces.ISSN:2041-172

Integrated Reconnaissance of the Physical and Biogeochemical Characteristics of Jamaica Bay

Researchers at The Earth Institute of Columbia University have carried out an integrated, coordinated pilot reconnaissance of the physical, chemical, geological, and biological systems within Jamaica Bay, entitled "Integrated Reconnaissance of the Physical and Biogeochemical Characteristics of Jamaica Bay." We believe that such an integrated approach is necessary to fully understand the complex inter-relationship of the wetland ecosystem. The program focused on obtaining a synergistic view of the varied elements of Jamaica Bay by carrying out coordinated research in four areas: submarine sediment morphology, sediment and soil sampling, circulation and mixing, and chemical analysis of the Bay waters

Towards a standards-compliant genomic and metagenomic publication record

Increasingly we are aware as a community of the growing need to manage the avalanche of genomic and metagenomic data, in addition to related data types like ribosomal RNA and barcode sequences, in a way that tightly integrates contextual data with traditional literature in a machine-readable way. It is for this reason that the Genomic Standards Consortium (GSC) formed in 2005. Here we suggest that we move beyond the development of standards and tackle standards-compliance and improved data capture at the level of the scientific publication. We are supported in this goal by the fact that the scientific community is in the midst of a publishing revolution. This revolution is marked by a growing shift away from a traditional dichotomy between 'journal articles' and 'database entries' and an increasing adoption of hybrid models of collecting and disseminating scientific information. With respect to genomes and metagenomes and related data types, we feel the scientific community would be best served by the immediate launch of a central repository of short, highly structured 'Genome Notes' that must be standards-compliant. This could be done in the context of an existing journal, but we also suggest the more radical solution of launching a new journal. Such a journal could be designed to cater to a wide range of standards-related content types that are not currently centralized in the published literature. It could also support the demand for centralizing aspects of the 'gray literature' (documents developed by institutions or communities) such as the call by the GSCl for a central repository of Standard Operating Procedures describing the genomic annotation pipelines of the major sequencing centers. We argue that such an 'eJournal', published under the Open Access paradigm by the GSC, could be an attractive publishing forum for a broader range of standardization initiatives within, and beyond, the GSC and thereby fill an unoccupied yet increasingly important niche within the current research landscape

Comparative Omics-Driven Genome Annotation Refinement: Application across Yersiniae

Genome sequencing continues to be a rapidly evolving technology, yet most downstream aspects of genome annotation pipelines remain relatively stable or are even being abandoned. The annotation process is now performed almost exclusively in an automated fashion to balance the large number of sequences generated. One possible way of reducing errors inherent to automated computational annotations is to apply data from omics measurements (i.e. transcriptional and proteomic) to the un-annotated genome with a proteogenomic-based approach. Here, the concept of annotation refinement has been extended to include a comparative assessment of genomes across closely related species. Transcriptomic and proteomic data derived from highly similar pathogenic Yersiniae (Y. pestis CO92, Y. pestis Pestoides F, and Y. pseudotuberculosis PB1/+) was used to demonstrate a comprehensive comparative omic-based annotation methodology. Peptide and oligo measurements experimentally validated the expression of nearly 40% of each strain's predicted proteome and revealed the identification of 28 novel and 68 incorrect (i.e., observed frameshifts, extended start sites, and translated pseudogenes) protein-coding sequences within the three current genome annotations. Gene loss is presumed to play a major role in Y. pestis acquiring its niche as a virulent pathogen, thus the discovery of many translated pseudogenes, including the insertion-ablated argD, underscores a need for functional analyses to investigate hypotheses related to divergence. Refinements included the discovery of a seemingly essential ribosomal protein, several virulence-associated factors, a transcriptional regulator, and many hypothetical proteins that were missed during annotation

Towards richer descriptions of our collection of genomes andmetagenomes

In this commentary, we advocate building a richer set of descriptions about our invaluable and exponentially growing collection of genomes and metagenomic datasets through the construction of consensus-driven data capture and exchange mechanisms. Standardization activities must proceed within the auspices of open-access and international working bodies, and to tackle the issues surrounding the development of better descriptions of genomic investigations we have formed the Genomic Standards Consortium (GSC). Here, we introduce the 'Minimum Information about a Genome Sequence' specification in the hopes of gaining wider participation in its development and discuss the resources that will be required to support it (standardization of annotations through the use of ontologies and mechanisms of metadata capture, exchange). As part of its wider goals, the GSC also strongly supports improving the 'transparency' of the information contained in existing genomic databases that contain calculated analyses and genomic annotations

The geochemical evolution of anorthosite residual magmas in the Laramie anorthosite complex, Wyoming

Olivine- and pyroxene-bearing Fe-enriched dioritic rocks in the 1434 Ma Laramie anorthosite complex are interpreted to represent variably fractionated and contaminated magmas residual after the crystallization of anorthosite. Geochemical characteristics of this suite include the following: high contents of TiO2, Fe2OT3, and P2O5 high incompatible trace element contents; rare earth element patterns with a large range of Eu anomalies; and isotopic compositions that reflect the geographic location of individual samples, with ISr increasing and εNd from south to north. After extraction from anorthosite, fractionation of ferrodioritic residual magmas resulted in secondary residual monzodioritic melts and complementary oxide-rich ferndiorite cumulates. Geographic trends in isotopic composition reflect an increasing Archean crustal component from south to north. Dioritic dikes and cumulates with isotopic compositions similar to associated anorthosites were derived locally. Large isotopic discrepancies between some diorites and their hosting anorthosites reflect preferential contamination of residual magma during ascent and emplacement of mantle-derived plagioclase-rich diapirs, followed by subsequent extraction and isolation of Fe-enriched interstitial melt. Strong isotopic contrasts between anorthosite and associated Fe-enriched rocks in anorthosite complexes do not preclude a direct relationship between them and reflect the diversity and complexity of processes during their petrogenesis.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
