BACKGROUND: Over the past four decades, the World Health Organization established the Expanded Programme on Immunization (EPI) to foster universal access to all relevant vaccines for all children at risk. The success of this program has been undeniable, but requires periodic monitoring to ensure that coverage rates remain high. The aim of this study was to measure the BCG vaccination coverage in Manhiça district, a high TB burden rural area of Southern Mozambique and to investigate factors that may be associated with BCG vaccination...

Protein folding and assembly into macromolecule complexes within the living cell are complex processes requiring intimate coordination. The biogenesis of complex iron sulfur molybdoenzymes (CISM) requires use of a system specific chaperone - a redox enzyme maturation protein (REMP) - to help mediate final folding and assembly. The CISM dimethyl sulfoxide (DMSO) reductase is a bacterial oxidoreductase that utilizes DMSO as a final electron acceptor for anaerobic respiration. The REMP DmsD strongly interacts with DMSO reductase to facilitate folding, cofactor-insertion, subunit assembly and targeting of the multi-subunit enzyme prior to membrane translocation and final assembly and maturation into a bioenergetic catalytic unit...

This study evaluates the transcriptionally active, dissimilatory sulfur- and arsenic-cycling components of the microbial community in alkaline, hypersaline Mono Lake, CA, USA. We sampled five depths spanning the redox gradient (10, 15, 18, 25 and 31 m) during maximum thermal stratification. We used custom databases to identify transcripts of genes encoding complex iron-sulfur molybdoenzyme (CISM) proteins, with a focus on arsenic (arrA, aioA and arxA) and sulfur cycling (dsrA, aprA and soxB), and assigned them to taxonomic bins...

BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked hereditary enzymatic abnormality that affects more than 400 million people worldwide. Most deficient individuals do not manifest any symptoms; however, several precipitant agents-such as fava intake, infections, or several drugs-may trigger acute haemolytic anaemia. Countries should be informed of the prevalence of this enzymatic anomaly within their borders, in order to make safe and appropriate national decisions regarding the use of potentially unsafe drugs for G6PD deficient individuals...

BACKGROUND: Redox enzyme maturation proteins (REMPs) describe a diverse family of prokaryotic chaperones involved in the biogenesis of anaerobic complex iron sulfur molybdoenzyme (CISM) respiratory systems. Many REMP family studies have focused on NarJ subfamily members from Escherichia coli: NarJ, NarW, DmsD, TorD and YcdY. The aim of this bioinformatics study was to expand upon the evolution, distribution and genetic association of these 5 REMP members within 130 genome sequenced taxonomically diverse species representing 324 Prokaryotic sequences...

Mental health service providers are at risk of experiencing compassion fatigue, burnout, and vicarious traumatization as a result of working in difficult contexts or when working with individuals who have experienced trauma. Numerous studies have examined the mitigating factors in professional caregivers' stress and related prevention strategies thought to be associated with professional self-care. This retrospective study examined the impact of debriefing strategies referred to as Critical Incident Stress Management (CISM) and spirituality in 22 mental health service providers working in a stressful, cross-cultural context...

Central to the field of trauma psychology is assessment of the impact of critical incidents on individuals, as measured by individual symptoms of stress. Accordingly, the trauma literature reflects a proliferation of clinical impact of event scales. Workplace incidents however, affect not only individual employees, but also work organizations, requiring a multi-level response. Critical incident stress management (CISM) is the most prevalent multi-level incident response strategy utilized by organizations, often through specialized CISM units operating within their employee assistance programs (EAPs)...

In complex systems, such as hospitals or air traffic control operations, critical incidents (CIs) are unavoidable. These incidents can not only become critical for victims but also for professionals working at the "sharp end" who may have to deal with critical incident stress (CIS) reactions that may be severe and impede emotional, physical, cognitive and social functioning. These CIS reactions may occur not only under exceptional conditions but also during every-day work and become an important safety issue...

There is debate in the literature regarding the definition and effectiveness of "early" critical incident stress management (CISM) interventions. Definitions range from interventions that take place within twelve hours (Everly and Mitchell, 1999; Stallard, Velleman, Salter & Howse, 2005) and up to a three month window (Bisson & Cohen, 2006). Others define early support as an intervention directly after an incident, before the individual leaves work and definitely before having their first sleep (Talbot, 1990; Snelgrove, 2000)...

BACKGROUND: Critical incidents in clinical medicine can have far-reaching consequences on patient health. In cases of severe medical errors they can seriously harm the patient or even lead to death. The involvement in such an event can result in a stress reaction, a so-called acute posttraumatic stress disorder in the healthcare provider, the so-called second victim of an adverse event. Psychological distress may not only have a long lasting impact on quality of life of the physician or caregiver involved but it may also affect the ability to provide safe patient care in the aftermath of adverse events...

The current article introduces Embedded Indigenous Psychological Support Teams (IPST) as a possible addition to current disaster relief efforts. This article highlights psychological first aid in an international context by drawing on mainstream disaster relief models such as The American Red Cross, Critical Incident Stress Management, and Flexible Psychological First Aid. IPST are explained as teams utilizing techniques from both CISM and FPFA with a focus on resiliency. It is currently theorized that in utilizing IPST existing disaster relief models may be more effective in mitigating negative physical or mental health consequences post-disaster...

On the basis of terror management theory (TMT) and cognitive-experiential self-theory (CEST), research has demonstrated that when individuals are experientially (rather than rationally)focused, mortality salience (MS) can engender world view defense in the form of increased in-group bias, increased favoritism toward others who uphold cultural values, and greater derogation of those who threaten them. The goal of the present study was to replicate previously observed effects of mortality salience on world view defense in a sample of disaster responders, specifically Criticallncident Stress Management (CISM) providers, and to examine the potential moderating effect of conceptual mode (rational versus experiential) on these effects...

BACKGROUND: The distinction between lobular neoplasia of the breast and ductal carcinoma in situ has important therapeutic implications. In some cases, it is very difficult to determine whether the morphology of the lesion is ductal or lobular. The aim of this study was to evaluate the value of E-cadherin and β-catenin expression through the immunophenotypical characterization of carcinoma in situ with mixed pattern (CISM). METHODS: A total of 25 cases of CISM were analyzed considering cytology/mixed architecture (ductal and lobular), nuclear pleomorphism, loss of cell cohesion, and presence of comedonecrosis...

Left-right coordination is essential for locomotor movements and is partly mediated by spinal commissural systems. Such coordination is also essential for reaching and manipulation in primates, but the role of spinal commissural systems here has not been studied. We investigated commissural connectivity to motoneurons innervating forelimb muscles using intracellular recordings in acutely anesthetized macaque monkeys. In 57 of 81 motoneurons, synaptic responses (52 of 57 excitatory) were evoked after contralateral intraspinal microstimulation in the gray matter (cISMS; 300 μA maximum current intensity)...

We have investigated the final steps of complex iron-sulfur molybdoenzyme (CISM) maturation using Escherichia coli DMSO reductase (DmsABC) as a model system. The catalytic subunit of this enzyme, DmsA, contains an iron-sulfur cluster (FS0) and a molybdo-bis(pyranopterin guanine dinucleotide) cofactor (Mo-bisPGD). We have identified a variant of DmsA (Cys59Ser) that renders enzyme maturation sensitive to molybdenum cofactor availability. DmsA-Cys59 is a ligand to the FS0 [4Fe-4S] cluster. In the presence of trace amounts of molybdate, the Cys59Ser variant assembles normally to the cytoplasmic membrane and supports respiratory growth on DMSO, although the ground state of FS0 as determined by EPR is converted from high-spin (S=3/2) to low-spin (S=1/2)...

Many metalloenzymes that inject and extract reducing equivalents at the beginning and the end of electron transport chains involved in chemiosmosis are suggested, through phylogenetic analysis, to have been present in the Last Universal Common Ancestor (LUCA). Their active centres are affine with the structures of minerals presumed to contribute to precipitate membranes produced on the mixing of hydrothermal solutions with the Hadean Ocean ~4 billion years ago. These mineral precipitates consist of transition element sulphides and oxides such as nickelian mackinawite ([Fe>Ni]2S2), a nickel-bearing greigite (~FeSS[Fe3NiS4]SSFe), violarite (~NiSS[Fe2Ni2S4]SSNi), a molybdenum bearing complex (~Mo(IV/VI)2Fe3S(0/2-)9) and green rust or fougerite (~[Fe(II)Fe(III)(OH)4](+)[OH](-))...

An evolutionary tree of key enzymes from the Complex-Iron-Sulfur-Molybdoenzyme (CISM) superfamily distinguishes "ancient" members, i.e. enzymes present already in the last universal common ancestor (LUCA) of prokaryotes, from more recently evolved subfamilies. The majority of the presented subfamilies and, as a consequence, the Molybdo-enzyme superfamily as a whole, appear to have existed in LUCA. The results are discussed with respect to the nature of bioenergetic substrates available to early life and to problems arising from the low solubility of molybdenum under conditions of the primordial Earth...

On November 5, 2009, an individual entered the Fort Hood Soldier Readiness Processing (SRP) site and opened fire with a handgun. The result of the shooting was a total of 13 people killed and 31 wounded. A two-person critical incident peer support (CIPS) team from the United States Army Military Police School (USAMPS) provided critical incident stress management (CISM) in the forms of critical incident stress debriefings (CISD) and one-on-one crisis intervention for investigators and their spouses. This article provides a summary and discussion of the results of the interventions that were conducted...
