Using 212 adolescents from a central-European country (mean age = 14.02, SD = 2.05, ranged from 11 to 18 years; females = 54%) and a multi-informant method to measure adolescents' behavioral and emotional adjustments, the present study explored three aspects regarding the attachment hierarchy. (1) The three types of behavioral systems of Rosenthal and Kobak's important people interview (IPI) were initially validated using an exploratory factor analysis with a US sample. Using a confirmatory factor analysis with a Czech sample, we replicated these three behavioral systems: attachment bond, support seeking, and affiliation. (2) We found that adolescents who developed attachment bond to multiple primary attachment figures were likely to score lower on both teacher-rated and parent-rated internalizing problems compared to those who had a single primary attachment figure. These multiple primary attachment figures tended to be family members (not peers). (3) Early adolescents who placed parents low in their attachment hierarchy scored higher on self-reported negative affect and lower on self-reported positive affect compared to early adolescents who placed parents high. The present study highlights multiple (vs. single) primary attachment figures as a protective factor and the premature reorganization of attachment hierarchy as a risk factor for adolescents' emotional and affective adjustments.

Background Human testicular germ cell tumors (TGCT) have a strong genetic component and a high familial relative risk. However, linkage analyses have not identified a rare, highly-penetrant familial TGCT (FTGCT) susceptibility locus. Currently, multiple low-penetrance genes are hypothesized to underlie the familial multiple-case phenotype. The observation that two is the most common number of affected individuals per family presents an impediment to FTGCT gene discovery. Clinically, the prospective TGCT risk in the multiple-case family context is unknown. Methods We performed a prospective analysis of TGCT incidence in a cohort of multiple-affected-person families and sporadic-bilateral-case families; 1,260 men from 140 families (10,207 person-years of follow-up) met our inclusion criteria. Age-, gender-, and calendar time-specific standardized incidence ratios (SIR) for TGCT relative to the general population were calculated using SEER*Stat. Results Eight incident TGCTs occurred during prospective FTGCT cohort follow-up (versus 0.67 expected; SIR=11.9; 95% confidence interval [CI]=5.1–23.4; excess absolute risk=7.2/10,000). We demonstrate that the incidence rate of TGCT is greater among bloodline male relatives from multiple-case testicular cancer families than that expected in the general population, a pattern characteristic of adult-onset Mendelian cancer susceptibility disorders. Two of these incident TGCTs occurred in relatives of sporadic-bilateral cases (0.15 expected; SIR=13.4; 95%CI=1.6–48.6). Conclusions Our data are the first indicating that despite relatively low numbers of affected individuals per family, members of both multiple-affected-person FTGCT families and sporadic-bilateral TGCT families comprise high-risk groups for incident testicular cancer. Impact Men at high TGCT risk might benefit from tailored risk stratification and surveillance strategies. PMID:26265202

The Bcl-2 family member BIM has multiple glaucoma-relevant functions in DBA/2J mice

Harder, Jeffrey M.; Fernandes, Kimberly A.; Libby, Richard T.

Axonal insult induces retinal ganglion cell (RGC) death through a BAX-dependent process. The pro-apoptotic Bcl-2 family member BIM is known to induce BAX activation. BIM expression increased in RGCs after axonal injury and its induction was dependent on JUN. Partial and complete Bim deficiency delayed RGC death after mechanical optic nerve injury. However, in a mouse model of glaucoma, DBA/2J mice, Bim deficiency did not prevent RGC death in eyes with severe optic nerve degeneration. In a subset of DBA/2J mice, Bim deficiency altered disease progression resulting in less severe nerve damage. Bim deficient mice exhibited altered optic nerve head morphology and significantly lessened intraocular pressure elevation. Thus, a decrease in axonal degeneration in Bim deficient DBA/2J mice may not be caused by a direct role of Bim in RGCs. These data suggest that BIM has multiple roles in glaucoma pathophysiology, potentially affecting susceptibility to glaucoma through several mechanisms. PMID:22833783

We have developed a wide-area-distribution storage system for multimedia databases, which minimizes the possibility of simultaneous failure of multiple disks in the event of a major disaster. It features a RAID system, whose member disks are spatially distributed over a wide area. Each node has a device, which includes the controller of the RAID and the controller of the member disks controlled by other nodes. The devices in the node are connected to a computer, using fiber optic cables and communicate using fiber-channel technology. Any computer at a node can utilize multiple devices connected by optical fibers as a single 'virtual disk.' The advantage of this system structure is that devices and fiber optic cables are shared by the computers. In this report, we first described our proposed system, and a prototype was used for testing. We then discussed its performance; i.e., how to read and write throughputs are affected by data-access delay, the RAID level, and queuing.

The complexity of cancer in multiple family members: dynamics of social work collaboration.

Snow, Alison; Gilbertson, Kristen

2011-01-01

This article presents a case study of one family affected by a cancer diagnosis in both the father and the daughter, who were diagnosed within the same time interval and who underwent treatment at the same time. The article examines the relationship between the caregivers and the oncology patient as well as with one another when the stress of diagnosis is compounded by multiple, simultaneous, and similar diagnoses in a highly condensed period of time. A thorough examination of the literature reveals that there are significant gaps regarding how multiple cancer diagnoses in one family affect the family dynamic, individual and collective coping styles, and caregiver burden. The diagnoses can also dramatically exacerbate economic stressors in a family. The coordination of psychosocial care from the perspectives of the adult and pediatric oncology social workers at an urban academic medical center will be discussed. The social work role, importance of collaboration, and family centered care perspective will be discussed as a method of easing the treatment experience for families in psychosocial distress.

Solidarity groups were established in eastern Democratic Republic of Congo to provide female survivors of conflict-related sexual violence an opportunity to generate income, establish networks of support, and cope with atrocities. Qualitative data were collected from 12 members of solidarity groups to explore factors that contributed to members' mental health. All women identified some improvement (physiological, psychological, economic, or social) since joining the solidarity group, but none of the women were free from ailments. Our findings suggest that a multifaceted intervention in women's own communities has the potential to improve multiple aspects of women's lives, including mental health.

Arsenic in Drinking Water in Bangladesh: Factors Affecting Child Health

The focus of this paper is to present an empirical model of factors affecting child health by observing actions households take to avoid exposure to arsenic in drinking water. Millions of Bangladeshis face multiple health hazards from high levels of arsenic in drinking water. Safe water sources are either expensive or difficult to access, affecting people’s individuals’ time available for work and ultimately affecting the health of household members. Since children are particularly susceptible and live with parents who are primary decision makers for sustenance, parental actions linking child health outcomes is used in the empirical model. Empirical results suggest that child health is significantly affected by the age and gender of the household water procurer. Adults with a high degree of concern for children’s health risk from arsenic contamination, and who actively mitigate their arsenic contaminated water have a positive effect on child health.

Partisan Joiners: Associational Membership and Political Polarization in the United States (1974–2004)*

Baldassarri, Delia

2013-01-01

Objectives Associational life may foster political integration or amplify division, depending on how individuals partition themselves into groups and whether their multiple affiliations embed them into concentric or cross-cutting social circles. Starting from this premise, I relate trends in associational membership to political partisanship, and ask if there is any evidence of increased political polarization in the associative patterns of Americans. Methods Using GSS data (1974–2004) on affiliations to 16 types of groups, I plot trends and run multilevel models to examine changes over time in the partisan allegiances of group members and patterns of overlapping memberships. Results The often-lamented decline in group membership affects primarily the category of single-group members and is limited to a few types of groups. The density of the network of overlapping memberships has remained stable over time and there are no real changes in the patterns of shared memberships between group types, nor do Republicans and Democrats differ in their patterns of preferential affiliation. Although political partisanship does not drive patterns of group affiliation, group members, especially those affiliated with multiple groups, are more radical in their partisan identification than nonmembers, and most types of groups have become politically more heterogeneous over time. Conclusion The puzzling finding that group types are not becoming more partisan, while group members are, leads to the hypothesis (to be tested in future research) that civil society polarization is occurring at the level of actual groups, and not group types.

Submarine groundwater discharge (SGD) plays a crucial role for the water quality of coastal waters due to associated fluxes of nutrients, organic compounds and/or heavy-metals. Thus, the quantification of SGD is essential for evaluating the vulnerability of coastal water bodies with regard to groundwater pollution as well as for understanding the matter cycles of the connected water bodies. Here, we present a scientific approach for quantifying discharge of fresh groundwater (GWf) and recirculated seawater (SWrec), including its short-term temporal dynamics, into the tide-affected Knysna estuary, South Africa. For a time-variant end-member mixing analysis we conducted time-series observations of radon (222Rn) and salinity within the estuary over two tidal cycles in combination with estimates of the related end-members for seawater, river water, GWf and SWrec. The mixing analysis was treated as constrained optimization problem for finding an end-member mixing ratio that simultaneously fits the observed data for radon and salinity best for every time-step. Uncertainty of each mixing ratio was quantified by Monte Carlo simulations of the optimization procedure considering uncertainty in end-member characterization. Results reveal the highest GWf and SWrec fraction in the estuary during peak low tide with averages of 0.8 % and 1.4 %, respectively. Further, we calculated a radon mass balance that revealed a daily radon flux of 4.8 * 108 Bq into the estuary equivalent to a GWf discharge of 29.000 m3/d (9.000-59.000 m3/d for 25th-75th percentile range) and a SWrec discharge of 80.000 m3/d (45.000-130.000 m3/d for 25th-75th percentile range). The uncertainty of SGD reflects the end-member uncertainty, i.e. the spatial heterogeneity of groundwater composition. The presented approach allows the calculation of mixing ratios of multiple uncertain end-members for time-series measurements of multiple parameters. Linking these results with a tracer mass balance allows conversion of end-member fractions to end-member fluxes.

Family and twin studies provide strong evidence that genetic factors are involved in the transmission of Gilles de la Tourette syndrome (TS) and related psychiatric disorders. To detect the underlying susceptibility gene(s) for TS, we performed linkage analysis in one large French Canadian family (127 members) from the Charlevoix region, in which 20 family members were definitely affected by TS and 20 others showed related tic disorders. Using model-based linkage analysis, we observed a LOD score of 3.24 on chromosome 11 (11q23). This result was obtained in a multipoint approach involving marker D11S1377, the marker for which significant linkage disequilibrium with TS recently has been detected in an Afrikaner population. Altogether, 25 markers were studied, and, for level of significance, we derived a criterion that took into account the multiple testing arising from the use of three phenotype definitions and three modes of inheritance, a procedure that yielded a LOD score of 3.18. Hence, even after adjustment for multiple testing, the present study shows statistically significant evidence for genetic linkage with TS. PMID:10986045

Cerebral gigantism is a syndrome consisting of characteristic dysmorphic features, accelerated growth in early childhood, and variable degrees of mental retardation. Its etiology and pathogenesis have not been defined. Three families are presented with multiple affected members. The vertical transmission of the trait and equal expression in both sexes in these families indicates a genetic etiology with a dominant pattern of inheritance, probably autosomal. As in previously reported cases, extensive endocrine evaluation failed to define the pathogenesis of the accelerated growth present in this disorder.

The diagnosis of inherited neuropathies can be challenging in several ways. First, a hereditary neuropathy must be suspected. Although some family histories are clear with multiple members affected, other families require directed inquiry. Second, even when a hereditary neuropathy is clear, it can be difficult to make a genetic characterization. The field of genotyping is expanding so rapidly, it is difficult to know what tests to order.

Introduction. Spinocerebellar ataxia 17 (SCA 17) is a rare autosomal dominant cerebellar ataxia (ADCA) caused by a CAG/CAA expansion in the TBP gene, reported from a limited number of countries. It is a very heterogeneous ADCA characterized by ataxia, cognitive decline, psychiatric symptoms, and involuntary movements, with some patients presenting with Huntington disease (HD) phenocopies. The SCA 17 expansion is stable during parent-child transmission and intrafamilial phenotypic homogeneity has been reported. However, significant phenotypic variability within families has also been observed. Report of the Family. We presently report a Greek family with a pathological expansion of 54 repeats at the SCA 17 locus that displayed remarkable phenotypic variability. Among 3 affected members, one presented with HD phenocopy; one with progressive ataxia, dementia, chorea, dystonia, and seizures, and one with mild slowly progressive ataxia with minor cognitive and affective symptoms. Conclusions. This is the first family with SCA 17 identified in Greece and highlights the multiple faces of this rare disorder, even within the same family.

The clinical features of patients infected with pulmonary nontuberculous mycobacteria (PNTM) are well described, but the genetic components of infection susceptibility are not. To examine genetic variants in patients with PNTM, their unaffected family members, and a control group. Whole-exome sequencing was done on 69 white patients with PNTM and 18 of their white unaffected family members. We performed a candidate gene analysis using immune, cystic fibrosis transmembrance conductance regulator (CFTR), cilia, and connective tissue gene sets. The numbers of patients, family members, and control subjects with variants in each category were compared, as was the average number of variants per person. A significantly higher number of patients with PNTM than the other subjects had low-frequency, protein-affecting variants in immune, CFTR, cilia, and connective tissue categories (35, 26, 90, and 90%, respectively). Patients with PNTM also had significantly more cilia and connective tissue variants per person than did control subjects (2.47 and 2.55 compared with 1.38 and 1.40, respectively; P = 1.4 × 10(-6) and P = 2.7 × 10(-8), respectively). Patients with PNTM had an average of 5.26 variants across all categories (1.98 in control subjects; P = 2.8 × 10(-17)), and they were more likely than control subjects to have variants in multiple categories. We observed similar results for family members without PNTM infection, with the exception of the immune category. Patients with PNTM have more low-frequency, protein-affecting variants in immune, CFTR, cilia, and connective tissue genes than their unaffected family members and control subjects. We propose that PNTM infection is a multigenic disease in which combinations of variants across gene categories, plus environmental exposures, increase susceptibility to the infection.

Chromosomal rearrangements are increasingly recognized to underlie neurologic disorders and are often accompanied by additional clinical signs beyond the gene-specific phenotypic spectrum. To elucidate the causal genetic variant in a large US family with co-occurrence of dopa-responsive dystonia as well as skeletal and eye abnormalities (ie, ptosis, myopia, and retina detachment). We examined 10 members of a family, including 5 patients with dopa-responsive dystonia and skeletal and/or eye abnormalities, from a US tertiary referral center for neurological diseases using multiple conventional molecular methods, including fluorescence in situ hybridization and array comparative genomic hybridization as well as large-insert whole-genome sequencing to survey multiple classes of genomic variations. Of note, there was a seemingly implausible transmission pattern in this family due to a mutation-negative obligate mutation carrier. Genetic diagnosis in affected family members and insight into the formation of large deletions. Four members were diagnosed with definite and 1 with probable dopa-responsive dystonia. All 5 affected individuals carried a large heterozygous deletion encompassing all 6 exons of GCH1. Additionally, all mutation carriers had congenital ptosis requiring surgery, 4 had myopia, 2 had retinal detachment, and 2 showed skeletal abnormalities of the hands, ie, polydactyly or syndactyly or missing a hand digit. Two individuals were reported to be free of any disease. Analyses revealed complex chromosomal rearrangements on chromosome 14q21-22 in unaffected individuals that triggered the expansion to a larger deletion segregating with affection status. The expansion occurred recurrently, explaining the seemingly non-mendelian inheritance pattern. These rearrangements included a deletion of GCH1, which likely contributes to the dopa-responsive dystonia, as well as a deletion of BMP4 as a potential cause of digital and eye abnormalities. Our findings alert neurologists to the importance of clinical red flags, ie, unexpected co-occurrence of clinical features that may point to the presence of chromosomal rearrangements as the primary disease cause. The clinical management and diagnostics of such patients requires an interdisciplinary approach in modern clinical-diagnostic care.

Germline mutations of EXT2, encoding Exostosin Glycosyltransferase 2, are associated with multiple osteochondromas (MO), an autosomal dominant disease characterized by the development of multiple peripheral cartilaginous benign tumors with a weak risk of malignant transformation. We report here a family with a remarkable clinical presentation characterized by the development of isolated chondrosarcomas, mostly located in ribs. Comparative analysis of exomes from two third-degree affected relatives led us to identify a single common disruptive variation, corresponding to a stop mutation (c.237G > A, p.Trp79*; (NM_000401.3); c.138G > A, p.Trp46*; (NM_207122.1)) within exon 2 of the EXT2 gene. Interestingly, no obvious sign of MO was detected in affected members by radiological examination. This report shows that germline mutations of EXT2 can result, not only in the development of multiple benign osteochondromas, but also in the development of isolated malignant cartilaginous tumors including central tumors, and that the presence of germline EXT2 mutation should be considered in patients suspected to have an inherited predisposition to chondrosarcoma, even in the absence of MO. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

This study aimed to determine the social aspects of multiple sclerosis (MS) in the Iranian individuals. A qualitative case study approach was used for this study, which is a part of a larger qualitative study about health care delivery system of MS. Participants were selected on the basis of purposive sampling method. Semi-structured interviews regarding the social aspects of MS were conducted with 18 MS patients, 6 family members and 7 health care providers. Besides interviews with the participants, documents related to the aim of the study, including weblogs, MS magazines, special websites of individuals with MS and news agencies. Data analysis was performed using the qualitative content analysis technique. Data obtained has been categorised into five main categories, including confronting stigma symbols, the outcome of stigma, walling-in due to stigma, disturbance in normal life and concern about job. There are multiple social effects of MS on the afflicted individuals, which affect various dimensions of their life. Policy makers and health care providers must also consider these effects of MS on other dimensions of the individuals' life. Implications for Rehabilitation Multiple sclerosis (MS) is a disease which restricts social life for patients, in addition to physical impacts. Individuals with MS experienced stigma as well as problems with employment and marital life, due to improper information about MS in society. We recommend that health care workers offer proper information about MS to patients and their family members to minimise the social problems faced by them. We recommend that mass media offers proper information about MS to people in society to disseminate the correct picture of MS. We recommend that the rehabilitation team offers psychological support to patients and their families for their empowerment, to facilitate dealing with the impacts of the disease. We recommend that health care providers teach the family members about patient support and communication skills.

Despite Increased Insurance Coverage, Nonwhite Sexual Minorities Still Experience Disparities In Access To Care.

PubMed

Previous studies suggest that members of sexual minority groups have poorer access to health services than heterosexuals. However, few studies have examined how sexual orientation interacts with gender and race to affect health care experience. Moreover, little is known about the role in health care disparities played by economic strains such as unemployment and poverty, which may result from prejudice and discrimination based on sexual orientation. Using data for 2013-15 from the National Health Interview Survey, we found that most members of sexual minority groups no longer have higher uninsurance rates than heterosexuals, but many continue to experience poorer access to high-quality care. Gay nonwhite men, bisexual white women, and bisexual and lesbian nonwhite women are disadvantaged in multiple aspects of access, compared to straight white men. Only some of these disparities are attributable to economic factors, which implies that noneconomic barriers to care are substantial. Our results suggest that the intersection of multiple social identities can reveal important gaps in health care experience. Making culturally sensitive services available may be key to closing the gaps. Project HOPE—The People-to-People Health Foundation, Inc.

Cys64Tyr) which was recently reported by our group. This is the third case report of a patient with CMTX developing MS, but it is unique in the fact that other family members carrying the same mutation were found to have asymptomatic central nervous system (CNS) involvement (diffuse white matter hyperintensity on brain MRI and extensor plantars). Although this may be a chance association, the increasing number of cases with CMTX and MS, especially with mutations involving the CNS, may imply some causative effect and provide insights into MS pathogenesis.

This is the third case report of a patient with CMTX developing MS, but it is unique in the fact that other family members carrying the same mutation were found to have asymptomatic central nervous system (CNS) involvement (diffuse white matter hyperintensity on brain MRI and extensor plantars). Although this may be a chance association, the increasing number of cases with CMTX and MS, especially with mutations involving the CNS, may imply some causative effect and provide insights into MS pathogenesis.

It is difficult for current simulation tools to simulate sequence data in a pre-specified pedigree structure and pre-specified affection status. Previously, we developed a flexible tool, SeqSIMLA2, for simulating sequence data in either unrelated case-control or family samples with different disease and quantitative trait models. Here we extended the tool to efficiently simulate sequences with multiple disease sites in large pedigrees with a given disease status for each pedigree member, assuming that the disease prevalence is low. SeqSIMLA2_exact is implemented with C++ and is available at http://seqsimla.sourceforge.net. © The Author 2015. Published by Oxford University Press. All rights reserved.

Patterns of split sex ratio in ants have multiple evolutionary causes based on different within-colony conflicts

PubMed Central

Kümmerli, Rolf; Keller, Laurent

2009-01-01

Split sex ratio—a pattern where colonies within a population specialize in either male or queen production—is a widespread phenomenon in ants and other social Hymenoptera. It has often been attributed to variation in colony kin structure, which affects the degree of queen–worker conflict over optimal sex allocation. However, recent findings suggest that split sex ratio is a more diverse phenomenon, which can evolve for multiple reasons. Here, we provide an overview of the main conditions favouring split sex ratio. We show that each split sex-ratio type arises due to a different combination of factors determining colony kin structure, queen or worker control over sex ratio and the type of conflict between colony members.

Two experiments examined the hypothesis that social rejection and perceived groupness function together to produce multiple-victim incidents of aggression. When a rejecter’s group membership is salient during an act of rejection, the rejectee ostensibly associates the rejecter’s group with rejection and retaliates against the group. Both experiments manipulated whether an aggregate of three persons appeared as separate individuals or members of an entity-like group and whether one of those persons rejected the participant. Consistent with the hypothesis, participants who experienced both rejection and perceived groupness behaved more aggressively against the aggregate (Experiment 1) and evidenced less favorable affective associations toward the aggregate (Experiment 2) than did participants who did not experience both rejection and perceived groupness.

HIV infection may be affected by multiple complex socioeconomic status (SES) factors, especially individual socioeconomic disadvantage and community-level inequality. At the same time, stigma towards HIV and marginalized groups has exacerbated persistent concentrated epidemics among key populations, such as persons who inject drugs (PWID) in Vietnam. Stigma researchers argue that stigma fundamentally depends on the existence of economic power differences in a community. In rapidly growing economies like Vietnam, the increasing gap in income and education levels, as well as an individual's absolute income and education, may create social conditions that facilitate stigma related to injecting drug use and HIV. A cross-sectional baseline survey assessing different types of stigma and key socioeconomic characteristics was administered to 1674 PWID and 1349 community members living in physical proximity throughout the 32 communes in Thai Nguyen province, Vietnam. We created four stigma scales, including HIV-related and drug-related stigma reported by both PWID and community members. We then used ecologic Spearman's correlation, ordinary least-squares regression and multi-level generalized estimating equations to examine community-level inequality associations, individual-level SES associations and multi-level SES associations with different types of stigma, respectively. There was little urban-rural difference in stigma among communes. Higher income inequality was marginally associated with drug-related stigma reported by community members (p=0.087), and higher education inequality was significantly associated with higher HIV-related stigma reported by both PWID and community members (p<0.05). For individuals, higher education was significantly associated with lower stigma (HIV and drug related) reported by both PWID and community members. Part-time employed PWID reported more experiences and perceptions of drug-related stigma, while conversely unemployed community members reported enacting lower drug-related stigma. Multi-level analysis revealed that the relationship between education inequality and HIV-related stigma is superseded by the effect of individual-level education. The results of the study confirm that socioeconomic factors at both the individual level and community level affect different types of stigma in different ways. Attention should be paid to these differences when planning structural or educational interventions to reduce stigma, and additional research should investigate the mechanisms with which SES and inequality affect social relationships and, in turn, stigma.

Using Theory to Design Evaluations of Communication Campaigns: The Case of the National Youth Anti-Drug Media Campaign.

PubMed

Hornik, Robert C; Yanovitzky, Itzhak

2003-05-01

We present a general theory about how campaigns can have effects and suggest that the evaluation of communication campaigns must be driven by a theory of effects. The National Youth Anti-Drug Media Campaign illustrates both the theory of campaign effects and implications that theory has for the evaluation design. Often models of effect assume that individual exposure affects cognitions that continue to affect behavior over a short term. Contrarily, effects may operate through social or institutional paths as well as through individual learning, require substantial levels of exposure achieved through multiple channels over time, take time to accumulate detectable change, and affect some members of the audience but not others. Responsive evaluations will choose appropriate units of analysis and comparison groups, data collection schedules sensitive to lagged effects, samples able to detect subgroup effects, and analytic strategies consistent with the theory of effects that guides the campaign.

Clinical and radiological assessment of a family with mild brachydactyly type A1: the usefulness of metacarpophalangeal profiles.

PubMed

Armour, C M; Bulman, D E; Hunter, A G

2000-04-01

The brachydactylies are a group of conditions in which various subtypes have been defined based upon the specific pattern of digital bones involved. Type A1 brachydactyly is principally characterised by maximal involvement of the middle phalanges. We report an extended family with a mild brachydactyly A1 which was, except for some short stature, not associated with any of the additional clinical findings reported in several published families. While all the hand bones tended to be small, the principal features of the affected members were shortened middle and distal phalanges, proximal 1st phalanges, and 5th metacarpals. The feet were similarly involved and tended to have a broad, slightly adducted forefoot. The two affected children showed multiple coned epiphyses. This paper provides a detailed description of the family including the radiographic signs and metacarpophalangeal profiles, which proved to be useful in distinguishing the mildly affected persons.

Put the Family Back in Family Health History: A Multiple-Informant Approach.

An accurate family health history is essential for individual risk assessment. This study uses a multiple-informant approach to examine whether family members have consistent perceptions of shared familial risk for four common chronic conditions (heart disease, Type 2 diabetes, high cholesterol, and hypertension) and whether accounting for inconsistency in family health history reports leads to more accurate risk assessment. In 2012-2013, individual and family health histories were collected from 127 adult informants of 45 families in the Greater Cincinnati Area. Pedigrees were linked within each family to assess inter-informant (in)consistency regarding common biological family member's health history. An adjusted risk assessment based on pooled pedigrees of multiple informants was evaluated to determine whether it could more accurately identify individuals affected by common chronic conditions, using self-reported disease diagnoses as a validation criterion. Analysis was completed in 2015-2016. Inter-informant consistency in family health history reports was 54% for heart disease, 61% for Type 2 diabetes, 43% for high cholesterol, and 41% for hypertension. Compared with the unadjusted risk assessment, the adjusted risk assessment correctly identified an additional 7%-13% of the individuals who had been diagnosed, with a ≤2% increase in cases that were predicted to be at risk but had not been diagnosed. Considerable inconsistency exists in individual knowledge of their family health history. Accounting for such inconsistency can, nevertheless, lead to a more accurate genetic risk assessment tool. A multiple-informant approach is potentially powerful when coupled with technology to support clinical decisions. Published by Elsevier Inc.

Circulating lipid components were studied under near-normal tropical conditions (around Lucknow) in 162 healthy volunteers - mostly medical students, staff members and members of their families (103 males and 59 females; 7 to 75y), subdivided into 4 age groups: A (7-20y; N=42), B (21-40y; N=60), C (41-60y; N=35) and D (61-75y; N=25). Blood samples were collected from each subject every 6h for 24h (4 samples). Plasma was separated and total cholesterol, high-density-lipoprotein (HDL) cholesterol, phospholipids and total lipids were measured spectrophotometrically. Data from each subject were analyzed by cosinor. We examined by multiple-analysis of variance how the MESOR (Midline Estimating Statistic Of Rhythm, a rhythm-adjusted mean) and the circadian amplitude of these variables is affected by gender, age, diet (vegetarian vs. omnivore), and smoking status. In addition to effects of gender and age, diet and smoking were found to affect the MESOR of circulating plasma lipid components in healthy Indians residing in northern India. Age also affected the circadian amplitude of these variables. These results indicate the possibility of using non-pharmacological interventions to improve a patient's metabolic profile before prescribing medication under near normal tropical conditions. They also add information that may help refine cut-off values in the light of factors shown here to affect blood lipids. Copyright © 2016 Elsevier B.V. All rights reserved.

Congenital abnormalities of the kidney and the urinary tract are the most common cause of pediatric kidney failure. These disorders are highly heterogeneous, and the etiologic factors are poorly understood. We performed genomewide linkage analysis and whole-exome sequencing in a family with an autosomal dominant form of congenital abnormalities of the kidney or urinary tract (seven affected family members). We also performed a sequence analysis in 311 unrelated patients, as well as histologic and functional studies. Linkage analysis identified five regions of the genome that were shared among all affected family members. Exome sequencing identified a single, rare, deleterious variant within these linkage intervals, a heterozygous splice-site mutation in the dual serine-threonine and tyrosine protein kinase gene (DSTYK). This variant, which resulted in aberrant splicing of messenger RNA, was present in all affected family members. Additional, independent DSTYK mutations, including nonsense and splice-site mutations, were detected in 7 of 311 unrelated patients. DSTYK is highly expressed in the maturing epithelia of all major organs, localizing to cell membranes. Knockdown in zebrafish resulted in developmental defects in multiple organs, which suggested loss of fibroblast growth factor (FGF) signaling. Consistent with this finding is the observation that DSTYK colocalizes with FGF receptors in the ureteric bud and metanephric mesenchyme. DSTYK knockdown in human embryonic kidney cells inhibited FGF-stimulated phosphorylation of extracellular-signal-regulated kinase (ERK), the principal signal downstream of receptor tyrosine kinases. We detected independent DSTYK mutations in 2.3% of patients with congenital abnormalities of the kidney or urinary tract, a finding that suggests that DSTYK is a major determinant of human urinary tract development, downstream of FGF signaling.

Non-syndromic aortic disease (NSAD) is a frequently asymptomatic but potentially lethal disease characterised by familial cases of thoracic aortic aneurysms and dissections. This monogenic but genetically heterogeneous condition is primarily inherited as an autosomal dominant disorder with low penetrance and variable expression. Mutations in ACTA2, TGFBR1, TGFBR2, MYH11, SMAD3, MYLK, and FBN1 genes have been described but still, there are many unresolved familial cases. The whole exome of two distantly related and affected members of a Spanish family with multiple cases of NSAD was analysed through 5500 SOLiD(™) System for the identification of shared and putative pathogenic variants. A new mutation termed c.C1042T:p.R348C (NM_001135599.2) was identified in TGFB2, a gene located in an evolutionary highly conserved region (Chr1: 218,519,577-218,617,961) that has been recently connected to this disease. The analysis of other family members using capillary sequencing confirmed cosegregation of the mutation with the disease and its incomplete penetrance. The repeated implication of TGFB2 in the development of thoracic aortic aneurysms and dissections suggests that this gene should be considered during genetic diagnosis of this disease. An accurate diagnosis of affected individuals and additional family members at risk allows for a personalised and more efficient gene-based follow-up and treatment. Finally, the reiterative presence of common musculoskeletal and craniofacial additional features in patients with TGFB2 mutations suggests the existence of a new yet undefined connective tissue syndrome responsible for not only aortic dilation, but also for the other extracardiac alterations present in the affected patients.

Signal transducers and activators of transcription proteins (STATs) act as important mediators in multiple biological processes induced by a large number of cytokines. In the present study, full-length cDNA sequences of seven STAT members, including some splicing variants different from those in mammals, were obtained from Synechogobius hasta. The phylogenetic analysis revealed that the seven STAT members were derived from paralogous genes that might have arisen by whole genome duplication (WGD) events during vertebrate evolution. All of these members share similar domain structure compared with those of mammals, and were widely expressed across the tested tissues (brain, gill, heart, intestine, liver, muscle and spleen), but at variable levels. Incubation in vitro of recombinant human leptin changed the intracellular triglyceride (TG) content and mRNA levels of several STATs members, as well as expressions and activities of genes involved in lipid metabolism. Furthermore, Tyrphostin B42 (AG490), a specific inhibitor of the Janus Kinase 2(JAK2)-STAT pathway, partially reversed leptin-induced change on STAT3 and its two spliced isoforms expression, as well as expressions and activities of genes involved in lipid metabolism. As a consequence, the decrease of TG content was also reversed. Thus, our study suggests that STAT3 is the requisite for the leptin signal and the activation of the STAT3 member may account for the leptin-induced changes in lipid metabolism in S. hasta.

Physical activity in subjects with multiple sclerosis with focus on gender differences: a survey

PubMed Central

2014-01-01

Background There is increasing research that examines gender-issues in multiple sclerosis (MS), but little focus has been placed on gender-issues regarding physical activity. The aim of the present study was to describe levels of physical activity, self-efficacy for physical activity, fall-related self-efficacy, social support for physical activity, fatigue levels and the impact of MS on daily life, in addition to investigating gender differences. Methods The sample for this cross-sectional cohort study consisted of 287 (84 men; 29.3%) adults with MS recruited from the Swedish Multiple Sclerosis Registry. A questionnaire was sent to the subjects consisting of the self-administrated measurements: Physical Activity Disability Survey – Revised, Exercise Self-Efficacy Scale, Falls- Efficacy Scale (Swedish version), Social Influences on Physical Activity, Fatigue Severity Scale and Multiple Sclerosis Impact Scale. Response rate was 58.2%. Results Men were less physically active, had lower self-efficacy for physical activity and lower fall-related self-efficacy than women. This was explained by men being more physically affected by the disease. Men also received less social support for physical activity from family members. The level of fatigue and psychological consequences of the disease were similar between the genders in the total sample, but subgroups of women with moderate MS and relapsing remitting MS experienced more fatigue than men. Conclusions Men were less physically active, probably a result of being more physically affected by the disease. Men being more physically affected explained most of the gender differences found in this study. However, the number of men in the subgroup analyses was small and more research is needed. A gender perspective should be considered in strategies for promoting physical activity in subjects with MS, e.g. men may need more support to be physically active. PMID:24612446

Osteopoikilosis and multiple exostoses caused by novel mutations in LEMD3 and EXT1 genes respectively - coincidence within one family

PubMed Central

2010-01-01

Background Osteopoikilosis is a rare autosomal dominant genetic disorder, characterised by the occurrence of the hyperostotic spots preferentially localized in the epiphyses and metaphyses of the long bones, and in the carpal and tarsal bones [1]. Heterozygous LEMD3 gene mutations were shown to be the primary cause of the disease [2]. Association of the primarily asymptomatic osteopokilosis with connective tissue nevi of the skin is categorized as Buschke-Ollendorff syndrome (BOS) [3]. Additionally, osteopoikilosis can coincide with melorheostosis (MRO), a more severe bone disease characterised by the ectopic bone formation on the periosteal and endosteal surface of the long bones [4-6]. However, not all MRO affected individuals carry germ-line LEMD3 mutations [7]. Thus, the genetic cause of MRO remains unknown. Here we describe a familial case of osteopoikilosis in which a novel heterozygous LEMD3 mutation coincides with a novel mutation in EXT1, a gene involved in aetiology of multiple exostosis syndrome. The patients affected with both LEMD3 and EXT1 gene mutations displayed typical features of the osteopoikilosis. There were no additional skeletal manifestations detected however, various non-skeletal pathologies coincided in this group. Methods We investigated LEMD3 and EXT1 in the three-generation family from Poland, with 5 patients affected with osteopoikilosis and one child affected with multiple exostoses. Results We found a novel c.2203C > T (p.R735X) mutation in exon 9 of LEMD3, resulting in a premature stop codon at amino acid position 735. The mutation co-segregates with the osteopoikilosis phenotype and was not found in 200 ethnically matched controls. Another new substitution G > A was found in EXT1 gene at position 1732 (cDNA) in Exon 9 (p.A578T) in three out of five osteopoikilosis affected family members. Evolutionary conservation of the affected amino acid suggested possible functional relevance, however no additional skeletal manifestations were observed other then those specific for osteopoikilosis. Finally in one member of the family we found a splice site mutation in the EXT1 gene intron 5 (IVS5-2 A > G) resulting in the deletion of 9 bp of cDNA encoding three evolutionarily conserved amino acid residues. This child patient suffered from a severe form of exostoses, thus a causal relationship can be postulated. Conclusions We identified a new mutation in LEMD3 gene, accounting for the familial case of osteopoikilosis. In the same family we identified two novel EXT1 gene mutations. One of them A598T co-incided with the LEMD3 mutation. Co-incidence of LEMD3 and EXT1 gene mutations was not associated with a more severe skeletal phenotype in those patients. PMID:20618940

Malignant hyperthermia (MH) is an autosomal dominant disorder that predisposes susceptible individuals to a potentially life-threatening crisis when exposed to commonly used anesthetics. Mutations in the skeletal muscle calcium release channel, ryanodine receptor (RYR1) are associated with MH in over 50% of affected families. Linkage analysis of the RYR1 gene region at 19q13 was performed in a large Brazilian family and a distinct disease co-segregating haplotype was revealed in the majority of members with diagnosis of MH. Subsequent sequencing of RYR1 mutational hot spots revealed a nucleotide substitution of C to T at position 7062, causing a novel amino acid change from Arg2355 to Cys associated with MH in the family. Haplotype analysis of the RYR1 gene area at 19q13 in the family with multiple MH members is an important tool in identification of genetic cause underlying this disease.

Traumatogenic Processes and Pathways to Mental Health Outcomes for Sexual Minorities Exposed to Bias Crime Information.

2015-07-01

Vicarious traumatization of nonvictim members of communities targeted by bias crimes has been suggested by previous qualitative studies and often dominates public discussion following bias events, but proximal and distal responses of community members have yet to be comprehensively modeled, and quantitative research on vicarious responses is scarce. This comprehensive review integrates theoretical and empirical literatures in social, clinical, and physiological psychology in the development of a model of affective, cognitive, and physiological responses of lesbian, gay, and bisexual individuals upon exposure to information about bias crimes.

Very few cases of intracranial aneurysms (IAs) in twins have been reported. Previous work has suggested that vulnerability to IA formation is heritable. Twin studies provide an opportunity to evaluate the impact of genetics on IA characteristics, including IA location. We therefore sought to examine IA location concordance, multiplicity, and rupture status within affected twin-pairs. The Familial Intracranial Aneurysm study was a multicenter study whose goal was to identify genetic and other risk factors for formation and rupture of IAs. The study required at least three affected family members or an affected sibling pair for inclusion. Subjects with fusiform aneurysms, an IA associated with an AVM, or a family history of conditions known to predispose to IA formation, such as polycystic kidney disease, Ehlers-Danlos syndrome, Marfan syndrome, fibromuscular dysplasia, or moyamoya syndrome were excluded. Twin-pairs were identified by birth date and were classified as monozygotic (MZ) or dizygotic (DZ) through DNA marker genotypes. In addition to zygosity, we evaluated twin-pairs by smoking status, major arterial territory of IAs, and rupture status. Location concordance was defined as the presence of an IA in the same arterial distribution (ICA, MCA, ACA, and vertebrobasilar), irrespective of laterality, in both members of a twin-pair. The Fisher exact test was used for comparisons between MZ and DZ twin-pairs. A total of 16 affected twin-pairs were identified. Location concordance was observed in 8 of 11 MZ twin-pairs but in only 1 of 5 DZ twin-pairs (p = 0.08). Three MZ subjects had unknown IA locations and comprised the three instances of MZ discordance. Six of the 11 MZ twin-pairs and none of the 5 DZ twin-pairs had IAs in the ICA distribution (p = 0.03). Multiple IAs were observed in 11 of 22 MZ and 5 of 10 DZ twin-pairs. Thirteen (13) of the 32 subjects had an IA rupture, including 10 of 22 MZ twins. We found that arterial location concordance was greater in MZ than DZ twins, which suggests a genetic influence upon aneurysm location. The 16 twin-pairs in the present study are nearly the total of affected twin-pairs that have been reported in the literature to date. Further studies are needed to determine the impact of genetics in the formation and rupture of IAs. © 2015 S. Karger AG, Basel.

Inequity-aversion and relative kindness intention jointly determine the expenditure of effort in project teams.

The literature on team cooperation has neglected the effects of relative kindness intention on cooperation, which we measure by comparing the kindness intentions of an agent to her group members to the kindness shown by other members to this same agent. We argue that the agent's emotional reaction to material payoff inequity is not constant, but rather affected by her relative kindness intention. Then, we apply the model to team projects with multiple partners and investigate how inequity-aversion and relative kindness intention jointly influence team cooperation. We first consider the case of homogeneous agents, where their marginal productivity levels and technical capacities are the same, and then consider the case of heterogeneous agents, where their marginal productivity levels and technical capacities are not the same. Our results show that inequity-aversion has no effect on effort expenditure in the former case, but does affect it in the latter case. The consideration of relative kindness intention may impact the agents' optimal cooperative effort expenditure when their technical capacities are different. In addition, it is beneficial for team cooperation, and might not only reduce the negative impact but also enhance the positive impact of inequity-aversion on the agents' effort expenditures.

Paget disease of bone (PDB) is a skeletal disorder characterized by focal abnormalities of bone remodeling, which result in enlarged and deformed bones in one or more regions of the skeleton. In some cases, the pagetic tissue undergoes neoplastic transformation, resulting in osteosarcoma and, less frequently, in giant cell tumor of bone (GCT). We performed whole-exome sequencing in a large family with 14 PDB-affected members, four of whom developed GCT at multiple pagetic skeletal sites, and we identified the c.2810C>G (p.Pro937Arg) missense mutation in the zinc finger protein 687 gene (ZNF687). The mutation precisely co-segregated with the clinical phenotype in all affected family members. The sequencing of seven unrelated individuals with GCT associated with PDB (GCT/PDB) identified the same mutation in all individuals, unravelling a founder effect. ZNF687 is highly expressed during osteoclastogenesis and osteoblastogenesis and is dramatically upregulated in the tumor tissue of individuals with GCT/PDB. Interestingly, our preliminary findings showed that ZNF687, indicated as a target gene of the NFkB transcription factor by ChIP-seq analysis, is also upregulated in the peripheral blood of PDB-affected individuals with (n = 5) or without (n = 6) mutations in SQSTM1, encouraging additional studies to investigate its potential role as a biomarker of PDB risk.

Mutational analysis of patients with neurofibromatosis 2

DOE Office of Scientific and Technical Information (OSTI.GOV)

MacCollin, M.; Ramesh, V.; Pulaski, K.

Neurofibromatosis 2 (NF2) is a genetic disorder characterized by the development of multiple nervous-system tumors in young adulthood. The NF2 gene has recently been isolated and found to encode a new member, merlin, of the protein 4.1 family of cytoskeleton-associated proteins. To define the molecular basis of NF2 in affected individuals, the authors have used SSCP analysis to scan the exons of the NF2 gene from 33 unrelated patients with NF2. Twenty unique SSCP variants were seen in 21 patients; 10 of these individuals were known to be the only affected person in their kindred, while 7 had at leastmore » one other known affected relative. In all cases in which family members were available, the SSCP variant segregated with the disease; comparison of sporadic cases with their parents confirmed the de novo variants. DNA sequence analysis revealed that 19 of the 20 variants observed are predicted to lead to a truncated protein due to frameshift, creation of a stop codon, or interference with normal RNA splicing. A single patient carried a 3-bp deletion removing a phenylalanine residue. The authors conclude that the majority of NF2 patients carry an inactivating mutation of the NF2 gene and that neutral polymorphism in the gene is rare. 18 refs., 3 figs., 2 tabs.« less

Escherichia coli is classified as a rod-shaped, Gram-negative bacterium in the family Enterobacteriaceae. The bacterium mainly inhabits the lower intestinal tract of warm-blooded animals, including humans, and is often discharged into the environment through feces or wastewater effluent. The presence of E. coli in environmental waters has long been considered as an indicator of recent fecal pollution. However, numerous recent studies have reported that some specific strains of E. coli can survive for long periods of time, and potentially reproduce, in extra-intestinal environments. This indicates that E. coli can be integrated into indigenous microbial communities in the environment. This naturalization phenomenon calls into question the reliability of E. coli as a fecal indicator bacterium (FIB). Recently, many studies reported that E. coli populations in the environment are affected by ambient environmental conditions affecting their long-term survival. Large-scale studies of population genetics provide the diversity and complexity of E. coli strains in various environments, affected by multiple environmental factors. This review examines the current knowledge on the ecology of E. coli strains in various environments in regards to its role as a FIB and as a naturalized member of indigenous microbial communities. Special emphasis is given on the growth of pathogenic E. coli in the environment, and the population genetics of environmental members of the genus Escherichia. The impact of environmental E. coli on water quality and public health is also discussed.

Original Research: The Benefits of Rapid Response Teams: Exploring Perceptions of Nurse Leaders, Team Members, and End Users.

2016-03-01

: The perceived benefits of rapid response teams (RRTs) influence whether RRTs are used and sustained. Perceived benefits are particularly important to sustaining RRTs when limited RRT data are shared with organizational members. Nurse leaders' perceptions of the benefits of RRTs likely influence their support, which is crucial for sustained RRT use. The perceptions of RRT members and end users similarly will affect use. But little is known regarding the perceptions of nurse leaders, RRT members, and RRT users in this regard.This study sought to explore and compare the perceptions of nurse leaders, RRT members, and RRT users regarding the benefits of RRTs.A qualitative, multiple-case study design was used. Semistructured interviews were conducted with nurse leaders, RRT members, and RRT users at four community hospitals, as part of a larger mixed-methods study examining RRT sustainability. Purposive and snowball sampling were used. Recruitment strategies included e-mail and listserv announcements, on-site presentations, direct personal contact, and a study flyer.All participants reported perceiving various ways that RRTs benefit the organization, staff members, and patients. Variations in the benefits perceived were observed between the three participant groups. Nurse leaders' perceptions tended to focus on macro-level benefits. RRT members emphasized the teaching and learning opportunities that RRTs offer. RRT users focused on the psychological support that RRTs can provide.Both similarities and differences were found between nurse leaders, RRT members, and RRT users regarding their perceptions of RRT benefits. Differences may be indicative of organizations' information-sharing processes; of variation in the priorities of nurse leaders, RRT members, and RRT users; and of the challenges nurses face daily in their work environments. Future research should investigate whether the perceived benefits of RRTs are borne out in actuality, as well as the relationships between the perceived benefits of RRTs and organizational and RRT characteristics.

Fibroblast growth factor (FGF) signaling is essential for normal and cancer biology. Mammalian FGF family members participate in multiple signaling pathways by binding to heparan sulfate and FGF receptors (FGFR) with varying affinities. FGF2 is the prototype member of the FGF family and interacts with its receptor to mediate receptor dimerization, phosphorylation, and activation of signaling pathways, such as Ras-MAPK and PI3K pathways. Excessive mitogenic signaling through the FGF/FGFR axis may induce carcinogenic effects by promoting cancer progression and increasing the angiogenic potential, which can lead to metastatic tumor phenotypes. Dysregulated FGF/FGFR signaling is associated with aggressive cancer phenotypes, enhanced chemotherapy resistance and poor clinical outcomes. In vitro experimental settings have indicated that extracellular FGF2 affects proliferation, drug sensitivity, and apoptosis of cancer cells. Therapeutically targeting FGF2 and FGFR has been extensively assessed in multiple preclinical studies and numerous drugs and treatment options have been tested in clinical trials. Diagnostic assays are used to quantify FGF2, FGFRs, and downstream signaling molecules to better select a target patient population for higher efficacy of cancer therapies. This review focuses on the prognostic significance of FGF2 in cancer with emphasis on therapeutic intervention strategies for solid and hematological malignancies. PMID:27007053

Alternative splicing for members of human mosaic domain superfamilies. I. The CH and LIM domains containing group of proteins.

PubMed

Friedberg, Felix

2009-05-01

In this paper we examine (restricted to homo sapiens) the products resulting from gene duplication and the subsequent alternative splicing for the members of a multidomain group of proteins which possess the evolutionary conserved calponin homology CH domain, i.e. an "actin binding domain", as a singlet and which, in addition, contain the conserved cysteine rich double Zn finger possessing Lim domain, also as a singlet. Seven genes, resulting from gene duplications, were identified that code for seven group members for which pre-mRNAs appear to have undergone multiple alternative splicing: Mical 1, 2 and 3 are located on chromosomes 6q21, 11p15 and 22q11, respectively. The LMO7 gene is present on chromosome 13q22 and the LIMCH1 gene on chromosome 4p13. Micall1 is mapped to chromosome 22q13 and Micall2 to chromosome 7p22. Translated Gen/Bank ESTs suggest the existence of multiple products alternatively spliced from the pre-mRNAs encoded by these genes. Characteristic indicators of such splicing among the proteins derived from one gene must include containment of some common extensive 100% identical regions. In some instances only one exon might be partly or completely eliminated. Sometimes alternative splicing is also associated with an increased frequency of creation of an exon or part of an exon from an intron. Not only coding regions for the body of the protein but also for its N- or -C ends could be affected by the splicing. If created forms are merely beginning at different starting points but remain identical in sequence thereafter, their existence as products of alternate splicing must be questioned. In the splicings, described in this paper, multiple isoforms rather than a single isoform appear as products during the gene expression.

Familial acromegaly/gigantism occurring in the absence of multiple endocrine neoplasia type I (MEN-1) or the Carney complex has been reported in 18 families since the biochemical diagnosis of GH excess became available, and the genetic defect is unknown. In the present study we examined 2 unrelated families with isolated acromegaly/gigantism. In family A, 3 of 4 siblings were affected, with ages at diagnosis of 19, 21, and 23 yr. In family B, 5 of 13 siblings exhibited the phenotype and were diagnosed at 13, 15, 17, 17, and 24 yr of age. All 8 affected patients had elevated basal GH levels associated with high insulin-like growth factor I levels and/or nonsuppressible serum GH levels during an oral glucose tolerance test. GHRH levels were normal in affected members of family A. An invasive macroadenoma was found in 6 subjects, and a microadenoma was found in 1 subject from family B. The sequence of the GHRH receptor complementary DNA in 1 tumor from family A was normal. There was no history of consanguinity in either family, and the past medical history and laboratory results excluded MEN-1 and the Carney complex in all affected and unaffected screened subjects. Five of 8 subjects have undergone pituitary surgery to date, and paraffin-embedded pituitary blocks were available for analysis. Loss of heterozygosity on chromosome 11q13 was studied by comparing microsatellite polymorphisms of leukocyte and tumor DNA using PYGM (centromeric) and D11S527 (telomeric), markers closely linked to the MEN-1 tumor suppressor gene. All tumors exhibited a loss of heterozygosity at both markers. Sequencing of the MEN-1 gene revealed no germline mutations in either family, nor was a somatic mutation found in tumor DNA from one subject in family A. The integrity of the MEN-1 gene in this subject was further supported by demonstration of the presence of MEN-1 messenger ribonucleic acid, as assessed by RT-PCR. These data indicate that loss of heterozygosity in these affected family members appears independent of MEN-1 gene changes and suggest that a novel (tissue-specific?) tumor suppressor gene(s) linked to the PYGM marker and expressed in the pituitary is essential for regulation of somatotrope proliferation.

The β Pictoris association low-mass members: Membership assessment, rotation period distribution, and dependence on multiplicity

Context. Low-mass members of young loose stellar associations and open clusters exhibit a wide spread of rotation periods. Such a spread originates from the distributions of masses and initial rotation periods. However, multiplicity can also play a significant role. Aims: We aim to investigate the role played by physical companions in multiple systems in shortening the primordial disk lifetime, anticipating the rotation spin up with respect to single stars. Methods: We have compiled the most extensive list to date of low-mass bona fide and candidate members of the young 25-Myr β Pictoris association. We have measured from our own photometric time series or from archival time series the rotation periods of almost all members. In a few cases the rotation periods were retrieved from the literature. We used updated UVWXYZ components to assess the membership of the whole stellar sample. Thanks to the known basic properties of most members we built the rotation period distribution distinguishing between bona fide members and candidate members and according to their multiplicity status. Results: We find that single stars and components of multiple systems in wide orbits (>80 AU) have rotation periods that exhibit a well defined sequence arising from mass distribution with some level of spread likely arising from initial rotation period distribution. All components of multiple systems in close orbits (<80 AU) have rotation periods that are significantly shorter than their equal-mass single counterparts. For these close components of multiple systems a linear dependence of rotation rate on separation is only barely detected. A comparison with the younger 13 Myr h Per cluster and with the older 40-Myr open clusters and stellar associations NGC 2547, IC 2391, Argus, and IC 2602 and the 130-Myr Pleiades shows that whereas the evolution of F-G stars is well reproduced by angular momentum evolution models, this is not the case for the slow K and early-M stars. Finally, we find that the amplitude of their light curves is correlated neither with rotation nor with mass. Conclusions: Once single stars and wide components of multiple systems are separated from close components of multiple systems, the rotation period distributions exhibit a well defined dependence on mass that allows us to make a meaningful comparison with similar distributions of either younger or older associations and clusters. Such cleaned distributions allow us to use the stellar rotation period meaningfully as an age indicator for F and G type stars.

Positive affective tone and team performance: The moderating role of collective emotional skills.

PubMed

Collins, Amy L; Jordan, Peter J; Lawrence, Sandra A; Troth, Ashlea C

2016-01-01

Research on affect as a group-level phenomenon has shown that over time, individual members within a group become highly similar in their affect (i.e., members experience and display similar emotions and moods), and often become similar enough that the aggregation of individuals' affect can meaningfully represent the "affective tone" of the group. It is generally assumed that a more positive affective tone will lead to better team performance. We challenge the conclusion that positive affective tone is always good for team performance, suggesting that the relationship between positive affective tone and team performance is subject to moderating influences. Across two studies, we demonstrate that the self-reported collective emotional skills of team members play a crucial role in determining whether positive affective tone is beneficial or detrimental to team performance. Implications for theory and practice are discussed.

Using Theory to Design Evaluations of Communication Campaigns: The Case of the National Youth Anti-Drug Media Campaign

PubMed Central

Hornik, Robert C.; Yanovitzky, Itzhak

2014-01-01

We present a general theory about how campaigns can have effects and suggest that the evaluation of communication campaigns must be driven by a theory of effects. The National Youth Anti-Drug Media Campaign illustrates both the theory of campaign effects and implications that theory has for the evaluation design. Often models of effect assume that individual exposure affects cognitions that continue to affect behavior over a short term. Contrarily, effects may operate through social or institutional paths as well as through individual learning, require substantial levels of exposure achieved through multiple channels over time, take time to accumulate detectable change, and affect some members of the audience but not others. Responsive evaluations will choose appropriate units of analysis and comparison groups, data collection schedules sensitive to lagged effects, samples able to detect subgroup effects, and analytic strategies consistent with the theory of effects that guides the campaign.

Substance abuse and child maltreatment.

PubMed

Wells, Kathryn

2009-04-01

Pediatricians and other medical providers caring for children need to be aware of the dynamics in the significant relationship between substance abuse and child maltreatment. A caregiver's use and abuse of alcohol, marijuana, heroin, cocaine, methamphetamine, and other drugs place the child at risk in multiple ways. Members of the medical community need to understand these risks because the medical community plays a unique and important role in identifying and caring for these children. Substance abuse includes the abuse of legal drugs as well as the use of illegal drugs. The abuse of legal substances may be just as detrimental to parental functioning as abuse of illicit substances. Many substance abusers are also polysubstance users and the compounded effect of the abuse of multiple substances may be difficult to measure. Often other interrelated social features, such as untreated mental illness, trauma history, and domestic violence, affect these families.

Shutoff of Host Gene Expression in Influenza A Virus and Herpesviruses: Similar Mechanisms and Common Themes

PubMed Central

Rivas, Hembly G.; Schmaling, Summer K.; Gaglia, Marta M.

2016-01-01

The ability to shut off host gene expression is a shared feature of many viral infections, and it is thought to promote viral replication by freeing host cell machinery and blocking immune responses. Despite the molecular differences between viruses, an emerging theme in the study of host shutoff is that divergent viruses use similar mechanisms to enact host shutoff. Moreover, even viruses that encode few proteins often have multiple mechanisms to affect host gene expression, and we are only starting to understand how these mechanisms are integrated. In this review we discuss the multiplicity of host shutoff mechanisms used by the orthomyxovirus influenza A virus and members of the alpha- and gamma-herpesvirus subfamilies. We highlight the surprising similarities in their mechanisms of host shutoff and discuss how the different mechanisms they use may play a coordinated role in gene regulation. PMID:27092522

microRNAs affect BCL-2 family proteins in the setting of cerebral ischemia

PubMed Central

Ouyang, Yi-Bing; Giffard, Rona G.

2014-01-01

The BCL-2 family is centrally involved in the mechanism of cell death after cerebral ischemia. It is well known that the proteins of the BCL-2 family are key regulators of apoptosis through controlling mitochondrial outer membrane permeabilization. Recent findings suggest that many BCL-2 family members are also directly involved in controlling transmission of Ca2+ from the endoplasmic reticulum (ER) to mitochondria through a specialization called the mitochondria-associated ER membrane (MAM). Increasing evidence supports the involvement of microRNAs (miRNA), some of them targeting BCL-2 family proteins, in the regulation of cerebral ischemia. In this mini-review, after highlighting current knowledge about the multiple functions of BCL-2 family proteins and summarizing their relationship to outcome from cerebral ischemia, we focus on the regulation of BCL-2 family proteins by miRNAs, especially miR-29 which targets multiple BCL-2 family proteins.

This retrospective study analyses post-mortem examination data of 251 homicide victims recorded by the Brescia Institute of Forensic Medicine between the years 1982 and 2012. The following variables were considered: year, month and day of death; gender, age and nationality of the victim; type of injurious mean; cause of death; homicide-suicides events; multiple murders; scene of death; toxicological data. Victims were usually young (30% was in the 21-30 years class) and males (64%). Although the victims were mostly Italians (73%), from 1990's more and more foreign victims appeared, following the migratory flow that affected Brescia County. The offenders frequently used firearms to kill their victims (41%), in particular for multiple murders. Sharp instruments were used mostly by foreigners. The study also emphasized 20 homicide-suicide events, mostly committed between intimates and family members. Copyright © 2013 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Spinal neurofibromatosis in a family with classical neurofibromatosis type 1 and a novel NF1 gene mutation.

PubMed

Nicita, Francesco; Torrente, Isabella; Spalice, Alberto; Bottillo, Irene; Papetti, Laura; Pinna, Valentina; Ursitti, Fabiana; Ruggieri, Martino

2014-02-01

Familial spinal neurofibromatosis (FSNF) is a rare form of neurofibromatosis type 1 (NF1) characterized by multiple, histologically proven neurofibromas of the spinal roots leaving no intact segments and associated neurofibromas of major peripheral nerves. It is sometimes associated with other NF1 stigmata. Most patients have NF1 gene mutations. We describe a patient who fulfilled the diagnostic criteria for spinal neurofibromatosis and belonged to a family in which other affected members exhibited classical NF1 stigmata. A novel missense (c.7109 T>A; p.Val2370Asp) mutation in exon 39 of the NF1 gene was present in the affected family members. The family displayed extreme phenotypic variability in the spectrum of NF1. To our knowledge, this is the first patient with spinal neurofibromatosis in the context of classical NF1 with an NF1 gene mutation. The term FSNF is inaccurate as this condition simply reflects the typical autosomal dominant pattern of NF1 inheritance with phenotypoc variability and does not encompass patients with sporadic disease or those in the context of a classical NF1 phenotype as reported in the present family. The term could be replaced by "spinal neurofibromatosis". Copyright © 2013 Elsevier Ltd. All rights reserved.

Ovarian development in a primitively eusocial wasp: social interactions affect behaviorally dominant and subordinate wasps in opposite directions relative to solitary females.

PubMed

Shukla, Shantanu; Pareek, Vidhi; Gadagkar, Raghavendra

2014-07-01

In many primitively eusocial wasp species new nests are founded either by a single female or by a small group of females. In the single foundress nests, the lone female develops her ovaries, lays eggs as well as tends her brood. In multiple foundress nests social interactions, especially dominance-subordinate interactions, result in only one 'dominant' female developing her ovaries and laying eggs. Ovaries of the remaining 'subordinate' cofoundresses remain suppressed and these individuals function as workers and tend the dominant's brood. Using the tropical, primitively eusocial polistine wasp Ropalidia marginata and by comparing wasps held in isolation and those kept as pairs in the laboratory, we demonstrate that social interactions affect ovarian development of dominant and subordinate wasps among the pairs in opposite directions, suppressing the ovaries of the subordinate member of the pair below that of solitary wasps and boosting the ovaries of dominant member of the pair above that of solitary females. In addition to being of physiological interest, such mirror image effects of aggression on the ovaries of the aggressors and their victims, suggest yet another mechanism by which subordinates can enhance their indirect fitness and facilitate the evolution of worker behavior by kin selection.

The literature on team cooperation has neglected the effects of relative kindness intention on cooperation, which we measure by comparing the kindness intentions of an agent to her group members to the kindness shown by other members to this same agent. We argue that the agent’s emotional reaction to material payoff inequity is not constant, but rather affected by her relative kindness intention. Then, we apply the model to team projects with multiple partners and investigate how inequity-aversion and relative kindness intention jointly influence team cooperation. We first consider the case of homogeneous agents, where their marginal productivity levels and technical capacities are the same, and then consider the case of heterogeneous agents, where their marginal productivity levels and technical capacities are not the same. Our results show that inequity-aversion has no effect on effort expenditure in the former case, but does affect it in the latter case. The consideration of relative kindness intention may impact the agents’ optimal cooperative effort expenditure when their technical capacities are different. In addition, it is beneficial for team cooperation, and might not only reduce the negative impact but also enhance the positive impact of inequity-aversion on the agents’ effort expenditures.

KLF4, p21 and context-dependent opposing forces in cancer.

PubMed

Rowland, Benjamin D; Peeper, Daniel S

Krüppel-like factors are transcriptional regulators that influence several cellular functions, including proliferation. Recent studies have shown that one family member, KLF4, can function both as a tumour suppressor and an oncogene. The ability of KLF4 to affect the levels of expression of the cell-cycle regulator p21 seems to be involved, in that this protein might function as a switch that determines the outcome of KLF4 signalling. Is this role of p21 restricted to KLF4, or does p21 represent a nodal point for signals from multiple other factors with opposing functions in cancer?

Chronic skin disease has a devastating effect on a person's physical and psychological well-being. Skin disease significantly impacts all aspects of a patient's life including school, relationships, career choices, social and leisure activities, and sexual life. The physical, psychological, and social consequences affect not only the patients, but also caregivers and family members as well. Common psychological problems associated with skin disease include, but are not limited to, feelings of stress, anxiety, anger, depression, shame, social isolation, low self-esteem, and embarrassment. Besides psychopharmacology, multiple psychotherapeutic techniques have proved to be helpful in addressing the psychological sequelae of skin disease. © Copyright 2018 Physicians Postgraduate Press, Inc.

What's in our soil?: how soil pollution affects earthworm movement patterns

Earthworms are an important member of many ecosystems because they contribute to soil quality and are a major food source for many organisms. In this project, we assessed the impacts soil pollution has on the burrowing patterns of earthworms. In each experiment, we introduced 10 earthworms to a unique pollutant and let them equilibrate for up to a week. The results indicated that earthworms migrate towards the introduced liquid regardless of its impact on them. The liquid pollutants introduced seemed to attract the earthworms. This can have harmful consequences, especially in the case of the motor oil, which killed multiple worms.

Family functioning in Huntington's disease (HD) is known from previous studies to be adversely affected. However, which aspects of family functioning are disrupted is unknown, limiting the empirical basis around which to create supportive interventions. The aim of the current study was to assess family functioning in HD families. We assessed family functioning in 61 participants (38 HD gene-expanded participants and 23 family members) using the McMaster Family Assessment Device (FAD; Epstein, Baldwin and Bishop, 1983), which provides scores for seven domains of functioning: Problem Solving; Communication; Affective Involvement; Affective Responsiveness; Behavior Control; Roles; and General Family Functioning. The most commonly reported disrupted domain for HD participants was Affective Involvement, which was reported by 39.5% of HD participants, followed closely by General Family Functioning (36.8%). For family members, the most commonly reported dysfunctional domains were Affective Involvement and Communication (both 52.2%). Furthermore, symptomatic HD participants reported more disruption to Problem Solving than pre-symptomatic HD participants. In terms of agreement between pre-symptomatic and symptomatic HD participants and their family members, all domains showed moderate to very good agreement. However, on average, family members rated Communication as more disrupted than their HD affected family member. These findings highlight the need to target areas of emotional engagement, communication skills and problem solving in family interventions in HD.

Ophoff, R.A.; Van Eijk, R.; Sandkuijl, L.A.

1994-07-01

Familial hemiplegic migraine (FHM) is a distinctive form of migraine with an autosomal dominant mode of inheritance. The migraine-like attacks are associated with transient hemiparesis. A locus for FHM has recently been assigned to chromosome 19 by linkage mapping. In the present study, five unrelated pedigrees with multiple members suffering from hemiplegic migraine were investigated. In two of the pedigrees additional symptoms, cerebellar ataxia and benign neonatal convulsions, respectively, were observed in affected members. Three pedigrees showed linkage to loci D19S391, D19S221, and D19S226 at chromosome 19p13. Haplotyping suggested a location of a FHM gene between D19S391 and D19S221. Inmore » the two remaining families, evidence against linkage was found. These results confirm the localization of a gene for familial hemiplegic migraine to the short arm of chromosome 19, but locus heterogeneity not corresponding to the observed clinical heterogeneity is likely to exist. 19 refs., 3 figs., 3 tabs.« less

The Hercules-Lyra association revisited. New age estimation and multiplicity study

Context. The Hercules-Lyra association, a purported nearby young moving group, contains a few tens of zero age main sequence stars of spectral types F to M. The existence and the properties of the Her-Lyr association are controversial and have been discussed in the literature. Aims: The present work reassesses the properties and the member list of the Her-Lyr association based on kinematics and age indicators. Many objects form multiple systems or have low-mass companions and so we need to properly account for multiplicity. Methods: We use our own new imaging observations and archival data to identify multiple systems. The colors and magnitudes of kinematic candidates are compared to isochrones. We derive further information on the age based on Li depletion, rotation, and coronal and chromospheric activity. A set of canonical members is identified to infer mean properties. Membership criteria are derived from the mean properties and used to discard non-members. Results: The candidates selected from the literature belong to 35 stellar systems, 42.9% of which are multiple. Four multiple systems (V538 Aur, DX Leo, V382 Ser, and HH Leo) are confirmed in this work by common proper motion. An orbital solution is presented for the binary system which forms a hierarchical triple with HH Leo. Indeed, a group of candidates displays signatures of youth. Seven canonical members are identified The distribution of Li equivalent widths of canonical Her-Lyr members is spread widely and is similar to that of the Pleiades and the UMa group. Gyrochronology gives an age of 257 ± 46 Myr which is roughly in between the ages of the Pleiades and the Ursa Major group. The measures of chromospheric and coronal activity support the young age. Four membership criteria are presented based on kinematics, lithium equivalent width, chromospheric activity, and gyrochronological age. In total, eleven stars are identified as certain members including co-moving objects plus additional 23 possible members while 14 candidates are doubtful or can be rejected. A comparison to the mass function, however, indicates the presence of a large number of additional low-mass members, which remain unidentified.

To report the autosomal dominant inheritance of the Jervell and Lange-Nielsen syndrome in a highly inbred family, the initiation of Torsades de Pointes, and the natural history of the syndrome based on a 16-year follow-up of the kindred. A family tree was constructed that included 66 blood relatives from three successive generations. Electrocardiograms were obtained from 59 living members including the proband, four members from a nuclear family, and 54 from the extended family. Evoked response audiometry was recorded for the proband and the nuclear family. All 59 family members were followed up regularly for 16 years. A total of 24 living members were affected--QTc: 480-680 ms. The proband had long QTc, bilateral high-tone sensorineural deafness, recurrent syncope, and Torsades de Pointes. The asymptomatic father had long QTc and unilateral high-tone sensorineural deafness that involved specifically the left ear. One asymptomatic sibling of the proband had long QTc and normal hearing. The mother and another sibling were asymptomatic; QTc and hearing were normal in both. A total of 21 affected members from the extended family had only long QTc, and all were asymptomatic. There were three congenitally deaf first cousins who had recurrent syncope and adrenergic-triggered sudden death. In all, seven of 10 parents had consanguineous marriage to a first cousin. Each affected offspring had at least one affected parent. The severely symptomatic proband who received only β-blocker therapy and the 23 affected members without antiadrenergic therapy, all remained asymptomatic throughout the 16-year follow-up period. Jervell and Lange-Nielsen syndrome was inherited as autosomal dominant in this kindred. The majority of the affected members had a mild phenotype. The severity of auditory and cardiac phenotypes corresponded.

Regulation of Bacteria-Induced Intercellular Adhesion Molecule-1 by CCAAT/Enhancer Binding Proteins

Manzel, Lori J.; Chin, Cecilia L.; Behlke, Mark A.; Look, Dwight C.

2009-01-01

Direct interaction between bacteria and epithelial cells may initiate or amplify the airway response through induction of epithelial defense gene expression by nuclear factor-κB (NF-κB). However, multiple signaling pathways modify NF-κB effects to modulate gene expression. In this study, the effects of CCAAT/enhancer binding protein (C/EBP) family members on induction of the leukocyte adhesion glycoprotein intercellular adhesion molecule-1 (ICAM-1) was examined in primary cultures of human tracheobronchial epithelial cells incubated with nontypeable Haemophilus influenzae. Increased ICAM-1 gene transcription in response to H. influenzae required gene sequences located at −200 to −135 in the 5′-flanking region that contain a C/EBP-binding sequence immediately upstream of the NF-κB enhancer site. Constitutive C/EBPβ was found to have an important role in epithelial cell ICAM-1 regulation, while the adjacent NF-κB sequence binds the RelA/p65 and NF-κB1/p50 members of the NF-κB family to induce ICAM-1 expression in response to H. influenzae. The expression of C/EBP proteins is not regulated by p38 mitogen-activated protein kinase activation, but p38 affects gene transcription by increasing the binding of TATA-binding protein to TATA-box–containing gene sequences. Epithelial cell ICAM-1 expression in response to H. influenzae was decreased by expressing dominant-negative protein or RNA interference against C/EBPβ, confirming its role in ICAM-1 regulation. Although airway epithelial cells express multiple constitutive and inducible C/EBP family members that bind C/EBP sequences, the results indicate that C/EBPβ plays a central role in modulation of NF-κB–dependent defense gene expression in human airway epithelial cells after exposure to H. influenzae.

2015-01-01

Psychiatric staff are faced with multiple forms of hostility, aggression, and assault at work, collectively referred to as workplace violence, which typically is activated by patients but can also come from coworkers and supervisors. Whether workplace violence adversely affects staff well-being may be related not only to its presence, but also to an individual’s stress reactivity. At a large public psychiatric hospital, an online survey was completed by 323 clinical care staff, of whom 69.5% had experienced physical assault in the previous 12 months. Staff well-being (depression, anger, and physical health) and staff safety concerns were adversely affected by conflicts with other staff members and by individual reactivity to social conflict and to assault. To improve staff well-being, in addition to safety protocols, interventions should target staff relationships, personal health maintenance practices, and individual coping skills for dealing with adverse workplace experiences.

Globally, road traffic injuries accounted for about 1.36 million deaths in 2015 and are projected to become the fourth leading cause of disability-adjusted life years (DALYs) lost by 2030. One-fifth of these deaths occurred in South Asia where road traffic injuries are projected to increase by 144% by 2020. Despite this rapidly increasing disease burden there is limited evidence on the economic burden of road traffic injuries on households in South Asia. We applied a novel coarsened exact matching method to assess the household economic burden of road traffic injuries using nationally representative World Health Survey data from five South Asian countries- Bangladesh, India, Nepal, Pakistan and Sri Lanka collected during 2002–2003. We examined the impact of road traffic injuries on household out-of-pocket (OOP) health spending, household non-medical consumption expenditure and the employment status of the traffic injury-affected respondent. We exactly matched a household (after ‘coarsening’) where a respondent reported being involved in a road traffic injury to households where the respondent did not report a road traffic injury on each of multiple observed household characteristics. Our analysis found that road traffic injury-affected households had significantly higher levels of OOP health spending per member (I$0.75, p<0.01), higher OOP spending on drugs per member (I$0.30, p = 0.03), and higher OOP hospital spending per member (I$0.29, p<0.01) in the four weeks preceding the survey. Indicators of “catastrophic spending” were also significantly higher in road traffic injury-affected households: 6.45% (p<0.01) for a threshold of OOP health spending to total household spending ratio of 20%, and 7.40% (p<0.01) for a threshold of OOP health spending to household ‘capacity to pay’ ratio of 40%. However, no statistically significant effects were observed for household non-medical consumption expenditure, and employment status of the road traffic injury-affected individual. Our analysis points to the need for financial risk protection against the road traffic injury-related OOP health expenditure and a focus on prevention. PMID:27768701

The objective of this investigation was to understand what family members know about the rights of individuals affected by mental illness. To this end, a qualitative exploratory study was conducted. A semi-structured interview was used for data collection. Eighteen family members were interviewed at a psychosocial care center (CAPS) and a civil society organization (CSO) located in a municipality in the state of São Paulo, Brazil, between March and September 2013. Data were analyzed using thematic content analysis and the following categories were constructed: mental health services and the rights of individuals affected by mental illness. We were able to infer that in addition to drug-based therapy, mental health services must provide therapeutic activities. Family members of those affected by mental illness were unaware of the Brazilian Psychiatric Reform Law and mentioned the following rights: welfare benefits, free public transport, basic food basket and medications.

Osteochondritis Dissecans Lesions in Family Members: Does a Positive Family History Impact Phenotypic Potency?

Although repetitive microtrauma and athletic overuse patterns are most commonly associated with osteochondritis dissecans (OCD), recent studies have identified a potential genetic predisposition for OCD. Several case series have documented family pedigrees that support autosomal-dominant inheritance, but the families in these studies were all selected as a result of unique histories that may not accurately represent OCD inheritance patterns at large. Because there has been little investigation beyond these case reports, we aimed to describe a broader, more representative pattern of OCD inheritance applicable to all affected patients. (1) What proportion of patients treated for OCD of the knee have one or more immediate and/or extended family members with a history of OCD lesions? (2) Do patients with more phenotypically potent lesions, which we defined as patients with bilateral OCD lesions or patients who have undergone multiple procedures for OCD, have a higher frequency of affected relatives than those with less potent lesions? This retrospective study queried patient databases, diagnosis codes (International Classification of Diseases, 9th Revision), and surgical logs at a regional, tertiary care children's hospital to identify all patients treated over a 10-year period (March 2004-March 2014) by the senior author for OCD of the knee. All patients aged 0-18 years at the time of diagnosis were included. At our institution, patients with intact lesions are treated with a trial of conservative therapy; conversely, patients with a break in the articular cartilage and/or loose fragments of bone/cartilage are treated surgically. There were no OCD-specific contraindications to surgery. This search identified 543 patients. After patient identification, a questionnaire was designed that asked for the number, age, and gender of all immediate family members and the history of OCD lesions in any family member (immediate or extended). For all positive family members, patients were further queried regarding relevant clinical details to affirm a history of OCD. Patients were contacted by mailed questionnaires and phone calls for survey completion. All 543 patients received the survey, of which 103 (19%) responded to it and were included here. Responders were approximately 1 year younger than nonresponders; there was no difference in gender distribution. A retrospective chart review was then conducted to collect demographic information, phenotypic disease severity, and treatment details. Of the 103 included patients, 20 patients (19%) with unilateral lesions were managed nonoperatively ("conservative" group), 50 patients (49%) had unilateral lesions advanced to surgery ("unilateral" group), 21 patients (20%) had bilateral lesions managed either conservatively or surgically ("bilateral" group), and 12 patients (12%) underwent multiple procedures for the same lesion ("multiple" group). Of those included, 75 patients (73%) were treated surgically. With the numbers available, there were no baseline differences among the groups in terms of gender, lesion laterality, lesion location, or number of secondary procedures at the time of the initial surgical intervention. In total, 14 of 103 (14%) patients treated for OCD in this study had an immediate and/or extended family member with a history of OCD lesions. This included four of 20 (20%) patients in the conservative group, five of 50 (10%) in the unilateral group, four of 21 (19%) in the bilateral group, and one of 12 (8%) in the multiple group. With the numbers available, we did not identify a higher proportion of immediate and/or extended family members with a positive history of OCD in those patients with phenotypically potent lesions (bilateral and multiple) as compared with those with patients phenotypically less potent lesions (conservative and unilateral; five of 33 [15%] versus nine of 70 [13%]; odds ratio, 1.2; 95% confidence interval, 0.4-3.9; p = 0.751). In this broad, heterogeneous cohort of pediatric patients with OCD, the proportion of patients with a positive family history of OCD was 14%, which appeared to be much higher than the reported prevalence of OCD in the general population according to prior research. Therefore, our data provide preliminary support for a familial inheritance pattern for OCD, suggesting that further clinical, biologic, and genomic investigation might help to improve our understanding of who is at highest risk for OCD and what moderating factors might influence their disease severity and risk of progression. Furthermore, our data suggest that expanded patient education and screening regarding inheritance patterns might enhance identification of potential familial disease burden and improve access to timely and appropriate treatment.

Melamine is a new risk of urinary stones. Gansu province is a heavily affected area and has large population and underdeveloped economy. We hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. A case-control study was performed among 190 infants. Results showed that the case group had less numbers of family members than the control (4.4 vs. 5.6, respectively). The multivariate logistic regression analysis indicated that number of family members was an independent influencing factor associated with urinary stones (OR, 0.606; 95% CI, 0.411–0.893; P = 0.011). Family income, however, did not exhibit a significant difference. Observed results suggested that number of family members was a new and significant influencing factor to affect the risk of melamine-associated urinary stones. PMID:23967433

Objective Multiple-room surgery has gained attention due to reports in the lay press scrutinizing the activity, with hospitals and the government collecting data on current practice. We studied practices and attitudes toward multiple-room surgery in otolaryngology. Methods A survey was developed by members of the Patient Safety and Quality Improvement Committee of the American Academy of Otolaryngology-Head and Neck Surgery. The survey was distributed to members of the Academy and included questions on demographics, current practices, and opinions regarding multiple-room surgery. The survey was designed to capture the spectrum of multidisciplinary, overlapping, and simultaneous/concurrent surgery practices. Data were collected via SurveyMonkey. Results A total of 907 of 9520 members completed the survey. Of the respondents, 40.4% reported performing some form of multiple-room surgery. Multiple-room surgery is more common amongst subspecialists than general otolaryngologists. Most believed that regulations disallowing multiple-room surgery would result in an increase in late starts (73.5%), an increase in the time to schedule surgery (84.5%), a detriment to residency training (63.1%), and no improvement in patient safety (60%.) Discussion Multiple-room surgery is common among responding otolaryngologists. Most respondents consider the practice to serve a role in facilitating access, efficiency, and training. Implications for Practice Due to recent attention placed on multiple-room surgery, institutions are reviewing policies regarding the practice. This survey suggests that policy changes that restrict multiple-room surgery must consider a potential unintended negative impact on patient care and access.

Family and Friends: Which Types of Personal Relationships Go Together in a Network?

PubMed

Rözer, Jesper; Mollenhorst, Gerald; Poortman, Anne-Rigt

We examine the link between family and personal networks. Using arguments about meeting opportunities, competition and social influence, we hypothesise how the presence of specific types of family members (i.e., a partner, children, parents and siblings) and non-family members (i.e., friends, neighbours and colleagues) in the network mutually affect one another. In addition, we propose that-beyond their mere presence-the active role of family members in the network strongly affects the presence of non-family members in the network. Data from the third wave of the Survey on the Social Networks of the Dutch, collected in 2012 and 2013, show that active involvement is of key importance; more than merely having family members present in one's personal network, the active involvement of specific types of family members in the personal network is associated with having disproportionally more other family members and having somewhat fewer non-family members in the network.

Bridges or Barriers? Conceptualization of the Role of Multiple Identity Gateway Groups in Intergroup Relations.

The modern era of globalization has been accompanied by a massive growth in interconnections between groups, and has led to the sharing of multiple identities by individuals and groups. Following these developments, research has focused on the issue of multiple identities, and has shed important light on how individuals who hold these complex forms of identity feel and behave, and on the reactions they elicit from members of other groups. However, the potential of groups with such multiple identities (e.g., biracials, immigrants, etc.) to affect the intergroup relations between the groups that represent the respective sources of the different identities (e.g., Blacks and Whites, country of origin and country of residence, etc.) has not been examined to date. Accordingly, in this paper, we first systematically explore the potential of groups in which people identify with multiple social categories, or groups that are perceived as such by others, to play a role in intergroup dynamics. Next, we offer a theoretical framework outlining what functions groups of people with shared multiple identities may serve (as bridges or barriers ) by proposing how their presence may facilitate or deteriorate intergroup relations. Finally, we present recent empirical research examining how groups of people with shared multiple identities can act as gateways and bridge the cleft between two separate groups that represent the respective sources of their different identities, and discuss the theoretical and practical implications for the field of intergroup relations.

Emotional influence in groups: the dynamic nexus of affect, cognition, and behavior.

van Kleef, Gerben A; Heerdink, Marc W; Homan, Astrid C

2017-10-01

Groups are a natural breeding ground for emotions. Group life affords unique opportunities but also poses critical challenges that may arouse emotional reactions in group members. Social-functional approaches hold that these emotions in turn contribute to group functioning by prompting group members to address concerns that are relevant to the group's success. Guided by Emotions as Social Information (EASI) theory, this paper reviews research on the affective, cognitive, and behavioral consequences of emotional expressions in groups. Affective processes include emotional contagion and affective convergence, and resulting states such as group affective tone and affective diversity. Cognitive processes include inferences group members draw from each other's emotional expressions. We discuss how these affective and cognitive processes shape behavior and group functioning. We conclude that the traditional (over)emphasis on affective processes must be complemented with a focus on cognitive processes to develop a more complete understanding of the social dynamics of emotions in groups.

The research examined the relationship between multiple social identifications and self-esteem. Early adolescents (M = 11.4, SD = .95) and mid-adolescents (M = 15.9, SD = 1.18) from Germany and Israel (n = 2337) were studied. Respondents described their social identification as students, family members, and as members of the majority national group and reported self-esteem. A longitudinal, cross-sectional and cross-cultural design revealed, as predicted, multiple social identifications related positively to self-esteem concurrently; they also related positively to self-esteem longitudinally over the course of a year. Moreover, multiple social identifications were found to be antecedent to self-esteem, not vice versa. Finally, multiple social identifications were found to decrease over time. The article discusses the contribution of multiple social identifications to self-esteem at different ages and in various contexts.

Escherichia coli is classified as a rod-shaped, Gram-negative bacterium in the family Enterobacteriaceae. The bacterium mainly inhabits the lower intestinal tract of warm-blooded animals, including humans, and is often discharged into the environment through faeces or wastewater effluent. The presence of E. coli in environmental waters has long been considered as an indicator of recent faecal pollution. However, numerous recent studies have reported that some specific strains of E. coli can survive for long periods of time, and potentially reproduce, in extraintestinal environments. This indicates that E. coli can be integrated into indigenous microbial communities in the environment. This naturalization phenomenon calls into question the reliability of E. coli as a faecal indicator bacterium (FIB). Recently, many studies reported that E. coli populations in the environment are affected by ambient environmental conditions affecting their long-term survival. Large-scale studies of population genetics revealed the diversity and complexity of E. coli strains in various environments, which are affected by multiple environmental factors. This review examines the current knowledge on the ecology of E. coli strains in various environments with regard to its role as a FIB and as a naturalized member of indigenous microbial communities. Special emphasis is given on the growth of pathogenic E. coli in the environment, and the population genetics of environmental members of the genus Escherichia. The impact of environmental E. coli on water quality and public health is also discussed. © 2017 The Society for Applied Microbiology.

To present a Greek family in which 5 male and 2 female members developed progressive spastic paraplegia. Plasma very long chain fatty acids (VLCFA) were reportedly normal at first testing in an affected male and for over 30 years the presumed diagnosis was hereditary spastic paraplegia (HSP). Targeted next generation sequencing (NGS) was used as a further diagnostic tool. Targeted exome sequencing in the proband, followed by Sanger sequencing confirmation; mutation segregation testing in multiple family members and plasma VLCFA measurement in the proband. NGS of the proband revealed a novel frameshift mutation in ABCD1 (c.1174_1178del, p.Leu392Serfs*7), bringing an end to diagnostic uncertainty by establishing the diagnosis of adrenomyeloneuropathy (AMN), the myelopathic phenotype of X-linked adrenoleukodystrophy (ALD). The mutation segregated in all family members and the diagnosis of AMN/ALD was confirmed by plasma VLCFA measurement. Confounding factors that delayed the diagnosis are presented. This report highlights the diagnostic utility of NGS in patients with undiagnosed spastic paraplegia, establishing a molecular diagnosis of AMN, allowing proper genetic counseling and management, and overcoming the diagnostic delay that can be rarely caused by false negative VLCFA analysis.

Professionalism is now an explicit part of the medical school curricula. To examine the components that are part of developing professionalism during the Rural Physician Associate Program (RPAP) experience, a 9-month rotation in a rural community during the third year of medical school. Two researchers analysed 3 years of essays for themes. IRB approval was obtained. Themes were organized using Van de Camp's model of professionalism. Students described how patients taught them about illnesses, the affects on their lives and the lives of their families. Preceptors role-modelled how to relate to patients with compassion and respect (Professionalism Towards the Patient). As a member of the health care team, clinic and hospital staff taught students how to be a good team member (Towards Other Health Care Professionals). Shadowing preceptors in their roles as physicians and community members, students learned about their responsibilities to the community (Towards the Public). Multiple opportunities for self-evaluation and reflection taught students to know themselves and find balance between work responsibilities and their personal lives (Towards Oneself). The RPAP appears to create a supportive learning environment that incorporates psychological safety, appreciation of differences, openness to new ideas and time for reflection - an ideal environment for developing professionalism.

We hypothesize that intensive care unit (ICU) families frequently perceive that they have received inconsistent information from staff about their relatives and that these inconsistencies influence abilities to make medical decisions, as well as satisfaction. We performed a prospective cohort study in the neurosciences and medical ICU at a university hospital. One hundred twenty-four family members of adult patients surviving to ICU discharge completed a questionnaire regarding perceptions of inconsistent information. Of 193 eligible patients, 64.2% had family complete the survey. Thirty-one respondents (25.0%; 95% confidence interval, 7.7) reported at least 1 instance of inconsistent information during their family member's admission, with no difference between the neurosciences ICU (21.5%; 9.3) and the medical ICU (31.1%; 14.1; P = .28). Of those who did receive inconsistent information, 38.7% (95% confidence interval, 18.2) reported multiple episodes and 74.2% (16.3) indicated that episodes occurred within the first 48 hours of admission. These episodes had an adverse effect, with 19.4% (14.7) indicating that they affected satisfaction and 9.7% (11.0) indicating that they made decision making difficult. Episodes involving inconsistent information from staff as perceived by families may be quite prevalent and may influence decision-making abilities and satisfaction.

Specific stressors associated with caregiving in Mexican American (MA) families are not well documented, yet caregiving issues are paramount because informal care for parents is central to their culture. Although MA families who band together to provide care for one member are not unique, the literature does not describe the phenomenon of collective caregiving, which may be widespread but unrecognized. This article describes these understudied families who are poorly served by contemporary health systems because their characteristics are unknown. Descriptive, multisite, longitudinal mixed-methods study of MA caregiving families. We identified three types of collective caregivers: those providing care for multiple family members simultaneously, those providing care successively to several family members, and/or those needing care themselves during their caregiving of others. Collective caregiving of MA elders warrants further investigation. Exploration of collective caregiving may provide a foundation for tailored family interventions.

Blast injuries are complex, severe, and outside of our everyday clinical practice, but every radiologist needs to understand them. By their nature, bomb blasts are unpredictable and affect multiple victims, yet require an immediate, coordinated, and whole-hearted response from all members of the clinical team, including all radiology staff. This article will help you gain the requisite expertise in blast imaging including recognising primary, secondary, and tertiary blast injuries. It will also help you understand the fundamental role that imaging plays during mass casualty attacks and how to avoid radiology becoming a bottleneck to the forward flow of severely injured patients as they are triaged and treated.

Does leader-affective presence influence communication of creative ideas within work teams?

PubMed

Madrid, Hector P; Totterdell, Peter; Niven, Karen

2016-09-01

Affective presence is a novel, emotion-related personality trait, supported in experimental studies, concerning the extent to which a person makes his or her interaction partners feel the same way (Eisenkraft & Elfenbein, 2010). Applying this concept to an applied teamwork context, we proposed that team-leader-affective presence would influence team members' communication of creative ideas. Multilevel modeling analysis of data from a survey study conducted with teams from a consultancy firm confirmed that team-leader-affective presence interacted with team-member creative idea generation to predict inhibition of voicing their ideas. Specifically, withholding of ideas was less likely when team members generated creative ideas and their team leader had higher positive affective presence or lower negative affective presence. These findings contribute to emotion research by showing affective presence as a trait with interpersonal meaning, which can shape how cognition is translated into social behavior in applied performance contexts, such as teamwork in organizations.

A lack of training in leadership and communication skills can place dentists at a disadvantage, leading to high degrees of staff-related stress and turnover. A dentist's leadership style directly affects an office's communication practices, and specific leadership behaviors affect the degree of team identity, interdependence and social distance (a measure of the influential power of team members). The author recruited 10 dental offices to take part in a study. Qualitative methods included in-depth interviews of one dentist, one senior staff member and one newer staff member from each office. The interview findings show that clear and definable relationships exist between leadership behaviors--hierarchical or team-oriented organizational perspectives, proactive or laissez-faire leadership styles, and autocratic or participative decision-making processes--and the team's communication practices. Decision-making processes directly affect the degree of team identification experienced by staff members, and conflict-management tactics affect team members' sense of interdependence and social distance. The findings of this study indicate that dentists should engage in participative decision-making processes that include staff members, thereby communicating their value to the practice and empowering employees. They also must become proactive in facilitating an environment that encourages collaboration and confrontation as healthy forms of conflict management. These leadership and communication behaviors are the most significant in creating a real rather than nominal team culture, which, in turn, leads to increased overall productivity, an enhanced level of services provided to patients and improved team member satisfaction.

Hereditary motor and sensory neuropathy with proximal dominancy (HMSN-P) is an adult-onset peripheral neurodegenerative disorder which has been reported only in the Okinawa Islands, Japan. The disease locus of "Okinawa-type" HMSN-P has been previously mapped to 3q13.1, with all affected individuals sharing an identical haplotype around the locus, suggesting that the undiscovered causative mutation in HMSN-P originated from a single founder. We have newly found two large families from the western part of Japan within which multiple members developed symptoms similar to those exhibited by HMSN-P patients from Okinawa, with no record of affinal connection between the islands. Using these pedigrees with "Kansai-type" HMSN-P, we carried out a linkage study utilizing eight microsatellite markers and identified a candidate region on 3q13.1 cosegregating with the disease (maximum two-point LOD score of 8.44 at theta=0.0) overlapping with the Okinawa-type HMSN-P locus. However, the disease haplotype shared among all affected members in these families was different from that in the Okinawa kindred, suggesting allelic heterogeneity. Such allelic variation should aid in the identification of the disease-causative gene. Moreover, the allelic heterogeneity of HMSN-P in the Japanese population suggests that HMSN-P may be more common across other ethnic groups, but classified into other disease categories.

Purpose: Schwannomatosis, a subtype of neurofibromatosis, is characterized by multiple benign, nonvestibular, nonintradermal schwannomas. Although the tumor suppressor SMARCB1 gene has been frequently identified as the underlying genetic cause of half of familial and ~10% of sporadic schwannomatosis, for most other cases, further causative genes remain to be discovered. Herein, we characterize the genome of a schwannomatosis family without constitutional inactivation of the SMARCB1 gene to explore novel genomic alterations predisposing individuals to the familial disease. Methods: We performed whole-genome/exome sequencing on genomic DNA of both schwannomatosis-affected and normal members of the family. Results: We identified a novel missense mutation (p.Asp208His; c.622G>C) in the coenzyme Q10 (CoQ10) biosynthesis monooxygenase 6 gene (COQ6) in schwannomatosis-affected members. The deleterious effects of the COQ6 mutations were validated by their lack of complementation in a coq6-deficient yeast mutant. Our study further indicated that the resultant haploinsufficiency of COQ6 might lead to CoQ10 deficiency and chronic overproduction of reactive oxygen species in Schwann cells. Conclusion: Although the exact oncogenetic mechanisms in this schwannomatosis family remain to be elucidated, our data strongly indicate a probable role of COQ6 mutation and CoQ10 deficiency in the development of familial schwannomatosis.

2016-03-01

Improving market orientation and patient safety have become the key concerns of nursing management. For nurses, establishing a patient safety climate is the key to enhancing nursing quality. This study explores how market orientation affects the climate of patient safety among hospital nurses. We proposed adopting a cross-sectional research design and using questionnaires to collect responses from nurses working in two Taiwanese hospitals. Three-hundred and forty-three valid samples were obtained. Multiple regression and path analyses were conducted to test the study. Market orientation was defined as the combination of customer orientation, competitor orientation, and interfunctional coordination. Customer orientation directly affects the climate of patient safety. Although the findings only supported Hypothesis 1, competitor orientation and interfunctional coordination positively affected the patient safety climate through the mediating effects of hospital support for staff. Health care managers could encourage nurses to adopt customer-oriented perspectives to enhance their nursing care. In addition, to enhance competitor orientation, interfunctional coordination, and the patient safety climate, hospital managers could strengthen their support for staff members. © The Author(s) 2014.

SUMO/sentrin specific protease 1 (Senp1) is an important regulation protease in the protein sumoylation, which affects the cell cycle, proliferation and differentiation. The role of Senp1 mediated protein desumoylation in pathophysiological progression of multiple myeloma is unknown. In this study, we demonstrated that Senp1 is overexpressed and induced by IL-6 in multiple myeloma cells. Lentivirus-mediated Senp1 knockdown triggers apoptosis and reduces viability, proliferation and colony forming ability of MM cells. The NF-κB family members including P65 and inhibitor protein IkBα play important roles in regulation of MM cell survival and proliferation. We further demonstrated that Senp1 inhibition decreased IL-6-induced P65more » and IkBα phosphorylation, leading to inactivation of NF-kB signaling in MM cells. These results delineate a key role for Senp1in IL-6 induced proliferation and survival of MM cells, suggesting it may be a potential new therapeutic target in MM. - Highlights: • Senp1 is overexpressed and induced by IL-6 in multiple myeloma cells. • Senp1 knockdown triggers apoptosis and reduces proliferation of MM cells. • Senp1 inhibition decreased IL-6-induced P65 and IkBα phosphorylation.« less

Nursing staff and their team: Impact on intention to leave.

The aim was to examine the relationship between the quality of team-member exchange experienced by nursing staff and their intention to leave. Job satisfaction and affective organizational commitment are considered as mediators. While the shortage of nurses is a management and policy priority, few studies have studied the relationships between nursing staff and their team, key organizational attitudes, and intentions to leave the organization. A questionnaire was administered to 217 registered nurses and nurse assistants in Belgium. Data were collected in 2012. To analyse the data, descriptive statistics, correlation, regression and path analyses were conducted. Team-member exchange has a positive impact on nursing staff satisfaction and affective commitment. Job satisfaction and affective organizational commitment fully mediated the impact of team-member exchange on nursing staff's intention to leave. This study illustrates the potential benefits of the positive influence of team-member exchange on key organizational attitudes of nursing staff, and the negative influence on intention to leave through affective commitment and job satisfaction. © 2015 International Council of Nurses.

To dissect the genetics of benign familial epilepsies of the first year of life and to assess the extent of the genetic overlap between benign familial neonatal seizures (BFNS), benign familial neonatal-infantile seizures (BFNIS), and benign familial infantile seizures (BFIS). Families with at least two first-degree relatives affected by focal seizures starting within the first year of life and normal development before seizure onset were included. Families were classified as BFNS when all family members experienced neonatal seizures, BFNIS when the onset of seizures in family members was between 1 and 4 months of age or showed both neonatal and infantile seizures, and BFIS when the onset of seizures was after 4 months of age in all family members. SCN2A, KCNQ2, KCNQ3, PPRT2 point mutations were analyzed by direct sequencing of amplified genomic DNA. Genomic deletions involving KCNQ2 and KCNQ3 were analyzed by multiple-dependent probe amplification method. A total of 46 families including 165 affected members were collected. Eight families were classified as BFNS, 9 as BFNIS, and 29 as BFIS. Genetic analysis led to the identification of 41 mutations, 14 affecting KCNQ2, 1 affecting KCNQ3, 5 affecting SCN2A, and 21 affecting PRRT2. The detection rate of mutations in the entire cohort was 89%. In BFNS, mutations specifically involve KCNQ2. In BFNIS two genes are involved (KCNQ2, six families; SCN2A, two families). BFIS families are the most genetically heterogeneous, with all four genes involved, although about 70% of them carry a PRRT2 mutation. Our data highlight the important role of KCNQ2 in the entire spectrum of disorders, although progressively decreasing as the age of onset advances. The occurrence of afebrile seizures during follow-up is associated with KCNQ2 mutations and may represent a predictive factor. In addition, we showed that KCNQ3 mutations might be also involved in families with infantile seizures. Taken together our data indicate an important role of K-channel genes beyond the typical neonatal epilepsies. The identification of a novel SCN2A mutation in a family with infantile seizures with onset between 6 and 8 months provides further confirmation that this gene is not specifically associated with BFNIS and is also involved in families with a delayed age of onset. Our data indicate that PRRT2 mutations are clustered in families with BFIS. Paroxysmal kinesigenic dyskinesia emerges as a distinctive feature of PRRT2 families, although uncommon in our series. We showed that the age of onset of seizures is significantly correlated with underlying genetics, as about 90% of the typical BFNS families are linked to KCNQ2 compared to only 3% of the BFIS families, for which PRRT2 represents the major gene.

Flight Schedule and the Circadian Clock Influence on Sleep Loss During Overnight Cargo Operations

Gander, Philippa H.; Gregory, Kevin B.; Rosekind, Mark R.; Shafto, Michael G. (Technical Monitor)

1995-01-01

Thirty-four flight crew members were monitored before, during, and after two 8-day overnight cargo duty patterns which involved multiple flights at night crossing no more than one time zone per 24 h. Rectal temperature, heart rate, and wrist activity were recorded every 2 min. Sleep quantity and quality, and nap timing, were noted in a logbook. To reduce the masking effects of physical activity on temperature, 0.28 C was added to each subject's raw temperature data whenever he reported being asleep. For both masked and unmasked data, daily temperature minima were estimated from the multiple complex demodulated waveform. The temperature minima did not show a progressive adaptation to night duty, which was interrupted by a night off after 5 nights on one trip pattern and after 3 nights on the other. On duty days, the average temperature minimum delayed by about 3 h, occurring near the end of the duty period. Daytime sleep episodes averaged 2.9 h shorter than nighttime sleep episodes, and were rated as lighter, less restorative, and poorer overall. Fifty-three percent of subjects slept more than once per 24 h while they were on night duty, compared to 17% when able to sleep at night. The total sleep per 24 h on duty days averaged 1.2 h less than pretrip. Twenty-nine percent of subjects lost more than 2 h of sleep per 24 h across the 8-day duty patterns. After night duty, subjects awoke around 1400 local time, even when they had slept 2-3 h less than a normal nocturnal sleep episode. Consequently, the duration of morning sleep episodes was correlated with the off-duty time (multiple r(sup 2)=0.44, F=37.23, p less than 0.0001). Anecdotally, crew members complained of being unable to sleep longer and not feeling well-rested. These wakeups were clustered 6 h after the temperature minimum, which suggests that they may have been a response to the circadian wakeup signal. Daytime layovers in which crew members were able to sleep again in the evening ended later (0200-0300) and were longer (average 19.2 h versus 14.8 h) than those in which they slept only once in the morning. Overnight cargo crew members are working around the time of the circadian nadir with an accumulating sleep debt. Two scheduling factors affect sleep loss during these operations: how long before the circadian wakeup signal crew members come off duty, and whether the layover lasts long enough to permit a second sleep episode in the early evening.

Cardiac involvement in facio-scapulo-humeral muscular dystrophy: a family study using Thallium-201 single-photon-emission-computed tomography.

Fifteen persons from two consecutive generations of one family affected with facio-scapulo-humeral muscular dystrophy (FSHD) were clinically and neurophysiologically examined. Diagnostic muscle biopsies were obtained from two members. Linkage analysis showed that all four affected members of the family inherit the same 4q35 haplotype giving a lod score of z = +1.44. Six family members were examined by ECG at rest and under stress, by two-dimensional echocardiography, and by cardiac Thallium-201 single-photon-emission computed tomography (Tl-201-SPECT) under dobutamine stress and at rest. Abnormal reduced Tl-201 uptake in cardiac SPECT was only found in the affected members of the family. Therefore we suggest that cardiac Tl-201-SPECT abnormalities in FSHD reflect cardiomyogenic changes in this type of muscular disease.

Deciphering Rashomon: an approach to verbal autopsies of maternal deaths.

PubMed

Iyer, Aditi; Sen, Gita; Sreevathsa, Anuradha

2013-01-01

The paper discusses an approach to verbal autopsies that engages with the Rashomon phenomenon affecting ex post facto constructions of death and responds to the call for maternal safety. This method differs from other verbal autopsies in its approach to data collection and its framework of analysis. In our approach, data collection entails working with and triangulating multiple narratives, and minimising power inequalities in the investigation process. The framework of analysis focuses on the missed opportunities for death prevention as an alternative to (or deepening of) the Three Delays Model. This framework assesses the behavioural responses of health providers, as well as community and family members at each opportunity for death prevention and categorises them into four groups: non-actions, inadequate actions, inappropriate actions and unavoidably delayed actions. We demonstrate the application of this approach to show how verbal autopsies can delve beneath multiple narratives and rigorously identify health system, behavioural and cultural factors that contribute to avoidable maternal mortality.

MicroRNAs affect BCL-2 family proteins in the setting of cerebral ischemia.

PubMed

Ouyang, Yi-Bing; Giffard, Rona G

2014-11-01

The BCL-2 family is centrally involved in the mechanism of cell death after cerebral ischemia. It is well known that the proteins of the BCL-2 family are key regulators of apoptosis through controlling mitochondrial outer membrane permeabilization. Recent findings suggest that many BCL-2 family members are also directly involved in controlling transmission of Ca(2+) from the endoplasmic reticulum (ER) to mitochondria through a specialization called the mitochondria-associated ER membrane (MAM). Increasing evidence supports the involvement of microRNAs (miRNAs), some of them targeting BCL-2 family proteins, in the regulation of cerebral ischemia. In this mini-review, after highlighting current knowledge about the multiple functions of BCL-2 family proteins and summarizing their relationship to outcome from cerebral ischemia, we focus on the regulation of BCL-2 family proteins by miRNAs, especially miR-29 which targets multiple BCL-2 family proteins.

Chorea Huntington is an autosomal dominantly inherited, neurodegenerative brain disorder that leads to involuntary hyperkinesia, psychotic symptoms and dementia. The illness not only changes the life of the person itself but also the world of the caregivers. The challenges in the care of a person which is affected by Chorea Huntington have an effect on the daily living as an assemblage of natural and social conditions. a multiple case study was conducted. It included semi-structured interviews with three caregivers of people with Chorea Huntington in South Tyrol. The qualitative data was analyzed using the qualitative structured analysis of Mayring (2007). The objective of this study was to describe the phenomenon of change of life from family members that care people affected by Chorea Huntington in a specific cultural setting (South Tyrol, Italy). The caregivers reported that the diagnosis of Chorea Huntington leads to negative changes in "relationship and family". Particularly, frustration, aggression, impatience and apathy were perceived as stressful. At the same time they highlight the positive changes through home care. They report that the relationship became more intimate and integral and it was characterized by more cohesion. Family caregivers get valuable support from the home care service, however, they complain that there is no facility in South Tyrol, which is specialized to care people with Chorea Huntington. Therefore, the caregivers have to "give up a lot" and don't have any personal desires, dreams and expectations for the future. The caregivers have learned independently to deal with their changed life step by step, and to see also the positive effects of the caring role. The life of family caregivers of a person which is affected by Chorea Huntington is characterized by abandonment. A continuous and professional care would be important for the affected and his caregiver. A continuous and professional care is important for both, addressing the care needs of the persons affected by Chorea Huntington and preparing their caregivers for the changing life.

A variant of Leber hereditary optic neuropathy characterized by recovery of vision and by an unusual mitochondrial genetic etiology.

The Tas2 and Vic2 Australian families are affected with a variant of Leber hereditary optic neuropathy (LHON). The risk of developing the optic neuropathy shows strict maternal inheritance, and the ophthalmological changes in affected family members are characteristic of LHON. However, in contrast to the common form of the disease, members of these two families show a high frequency of vision recovery. To ascertain the mitochondrial genetic etiology of the LHON in these families, both (a) the the nucleotide sequences of the seven mitochondrial genes encoding subunits of respiratory-chain complex I and (b) the mitochondrial cytochrome b gene were determined for representatives of both families. Neither family carries any of the previously identified primary mitochondrial LHON mutations: ND4/11778, ND1/3460, or ND1/4160. Instead, both LHON families carry multiple nucleotide changes in the mitochondrial complex I genes, which produce conservative amino acid changes. From the available sequence data, it is inferred that the Vic2 and Tas2 LHON families are phylogenetically related to each other and to a cluster of LHON families in which mutations in the mitochondrial cytochrome b gene have been hypothesized to play a primary etiological role.

There are two hypotheses to account for the unusual mitochondrial genetic etiology of the LHON in the Tas2 and Vic2 LHON families.

The Tas2 and Vic2 Australian families are affected with a variant of Leber hereditary optic neuropathy (LHON). The risk of developing the optic neuropathy shows strict maternal inheritance, and the opthalmological changes in affected family members are characteristic of LHON. However, in contrast to the common form of the disease, members of these two families show a high frequency of vision recovery.

Reaching the boundary between stellar kinematic groups and very wide binaries. III. Sixteen new stars and eight new wide systems in the β Pictoris moving group

Aims: We look for common proper motion companions to stars of the nearby young β Pictoris moving group. Methods: First, we compiled a list of 185 β Pictoris members and candidate members from 35 representative works. Next, we used the Aladin and STILTS virtual observatory tools and the PPMXL proper motion and Washington Double Star catalogues to look for companion candidates. The resulting potential companions were subjects of a dedicated astro-photometric follow-up using public data from all-sky surveys. After discarding 67 sources by proper motion and 31 by colour-magnitude diagrams, we obtained a final list of 36 common proper motion systems. The binding energy of two of them is perhaps too small to be considered physically bound. Results: Of the 36 pairs and multiple systems, eight are new, 16 have only one stellar component previously classified as a β Pictoris member, and three have secondaries at or below the hydrogen-burning limit. Sixteen stars are reported here for the first time as moving group members. The unexpected large number of high-order multiple systems, 12 triples and two quadruples among 36 systems, may suggest a biased list of members towards close binaries or an increment of the high-order-multiple fraction for very wide systems.

Understanding Mental Illness Stigma Toward Persons With Multiple Stigmatized Conditions: Implications of Intersectionality Theory.

PubMed

Oexle, Nathalie; Corrigan, Patrick W

2018-05-01

People with mental illness are often members of multiple stigmatized social groups. Therefore, experienced disadvantage might not be determined solely by mental illness stigma. Nevertheless, most available research does not consider the effects and implications of membership in multiple stigmatized social groups among people with mental illness. Reflecting on intersectionality theory, the authors discuss two intersectional effects determining disadvantage among people with mental illness who are members of multiple stigmatized social groups, namely double disadvantage and prominence. To be effective, interventions to reduce disadvantage experienced by people with mental illness need to be flexible and targeted rather than universal in order to address the implications of intersectionality. Whereas education-based approaches usually assume homogeneity and use universal strategies, contact-based interventions consider diversity among people with mental illness.

There is well-known heterogeneity in affective mechanisms in depression that may extend to positive affect. We used data-driven parsing of neural connectivity to reveal subgroups present across depressed and healthy individuals during positive processing, informing targets for mechanistic intervention. Ninety-two individuals (68 depressed patients, 24 never-depressed control subjects) completed a sustained positive mood induction during functional magnetic resonance imaging. Directed functional connectivity paths within a depression-relevant network were characterized using Group Iterative Multiple Model Estimation (GIMME), a method shown to accurately recover the direction and presence of connectivity paths in individual participants. During model selection, individuals were clustered using community detection on neural connectivity estimates. Subgroups were externally tested across multiple levels of analysis. Two connectivity-based subgroups emerged: subgroup A, characterized by weaker connectivity overall, and subgroup B, exhibiting hyperconnectivity (relative to subgroup A), particularly among ventral affective regions. Subgroup predicted diagnostic status (subgroup B contained 81% of patients; 50% of control subjects; χ 2 = 8.6, p = .003) and default mode network connectivity during a separate resting-state task. Among patients, subgroup B members had higher self-reported symptoms, lower sustained positive mood during the induction, and higher negative bias on a reaction-time task. Symptom-based depression subgroups did not predict these external variables. Neural connectivity-based categorization travels with diagnostic category and is clinically predictive, but not clinically deterministic. Both patients and control subjects showed heterogeneous, and overlapping, profiles. The larger and more severely affected patient subgroup was characterized by ventrally driven hyperconnectivity during positive processing. Data-driven parsing suggests heterogeneous substrates of depression and possible resilience in control subjects in spite of biological overlap. Copyright © 2016 Society of Biological Psychiatry.

Pigment dispersion syndrome affects up to 4% of the white population. It is characterized by the presence of transillumination defects, Krukenberg's spindle and dense trabecular meshwork pigmentation. Open-angle glaucoma will develop in as many as 50% of affected patients. In this study we describe the familial occurrence of pigment dispersion syndrome in six North American pedigrees and the phenotypic characteristics with respect to pigment dispersion syndrome and glaucoma. Probands with pigment dispersion syndrome were identified in glaucoma clinics at university eye centres in Ottawa and Durham, NC. Families with two or more affected members were evaluated. All willing members in each family underwent a thorough clinical examination and were classified as affected with pigment dispersion syndrome, suspect or unaffected. The previous medical records were reviewed to obtain the past medical and ocular history, including risk factors for glaucoma. All six families are white. Three families show at least two generations of affected members. Of the 43 subjects examined 58% were women. All 14 affected members showed moderate to heavy trabecular meshwork pigmentation and either Krukenberg's spindle or transillumination defects. The affected members were also considerably more myopic (mean spherical equivalent for the right eye -4.72 dioptres) than the suspect group or the unaffected group (mean spherical equivalent -0.79 D and +1.19 D respectively) (p < or = 0.001), and the intraocular pressure was higher for the affected than the unaffected group (mean for the right eye 20 mm Hg vs. 16 mm Hg) (p = 0.004). Half of those affected also had open-angle glaucoma. We have identified and phenotypically characterized six North American families with autosomal dominant pigment dispersion syndrome. Our ultimate goal is to identify the gene(s) that causes this disorder in order to clarify its molecular etiology and pathophysiology. This may give rise to a molecular classification of the disease as well as provide the foundation for genetic testing and new treatment approaches.

How similar are recognition memory and inductive reasoning?

PubMed

Hayes, Brett K; Heit, Evan

2013-07-01

Conventionally, memory and reasoning are seen as different types of cognitive activities driven by different processes. In two experiments, we challenged this view by examining the relationship between recognition memory and inductive reasoning involving multiple forms of similarity. A common study set (members of a conjunctive category) was followed by a test set containing old and new category members, as well as items that matched the study set on only one dimension. The study and test sets were presented under recognition or induction instructions. In Experiments 1 and 2, the inductive property being generalized was varied in order to direct attention to different dimensions of similarity. When there was no time pressure on decisions, patterns of positive responding were strongly affected by property type, indicating that different types of similarity were driving recognition and induction. By comparison, speeded judgments showed weaker property effects and could be explained by generalization based on overall similarity. An exemplar model, GEN-EX (GENeralization from EXamples), could account for both the induction and recognition data. These findings show that induction and recognition share core component processes, even when the tasks involve flexible forms of similarity.

Surgical quality assessment. A simplified approach.

PubMed

DeLong, D L

1991-10-01

The current approach to QA primarily involves taking action when problems are discovered and designing a documentation system that records the deliverance of quality care. Involving the entire staff helps eliminate problems before they occur. By keeping abreast of current problems and soliciting input from staff members, the QA at our hospital has improved dramatically. The cross-referencing of JCAHO and AORN standards on the assessment form and the single-sheet reporting form expedite the evaluation process and simplify record keeping. The bulletin board increases staff members' understanding of QA and boosts morale and participation. A sound and effective QA program does not require reorganizing an entire department, nor should it invoke negative connotations. Developing an effective QA program merely requires rethinking current processes. The program must meet the department's specific needs, and although many departments concentrate on documentation, auditing charts does not give a complete picture of the quality of care delivered. The QA committee must employ a variety of data collection methods on multiple indicators to ensure an accurate representation of the care delivered, and they must not overlook any issues that directly affect patient outcomes.

Whole-exome sequencing, without prior linkage, identifies a mutation in LAMB3 as a cause of dominant hypoplastic amelogenesis imperfecta.

The conventional approach to identifying the defective gene in a family with an inherited disease is to find the disease locus through family studies. However, the rapid development and decreasing cost of next generation sequencing facilitates a more direct approach. Here, we report the identification of a frameshift mutation in LAMB3 as a cause of dominant hypoplastic amelogenesis imperfecta (AI). Whole-exome sequencing of three affected family members and subsequent filtering of shared variants, without prior genetic linkage, sufficed to identify the pathogenic variant. Simultaneous analysis of multiple family members confirms segregation, enhancing the power to filter the genetic variation found and leading to rapid identification of the pathogenic variant. LAMB3 encodes a subunit of Laminin-5, one of a family of basement membrane proteins with essential functions in cell growth, movement and adhesion. Homozygous LAMB3 mutations cause junctional epidermolysis bullosa (JEB) and enamel defects are seen in JEB cases. However, to our knowledge, this is the first report of dominant AI due to a LAMB3 mutation in the absence of JEB.

Public health researchers repeatedly represent women as a group vulnerable to ill health. This has been particularly true in the field of HIV research, where women are disproportionately affected by HIV in terms of disease burden and the social effects of the epidemic. Although women have been the focus of many prevention and treatment programs, structural barriers to implementation of these targeted programs persist. In this article we explore how high HIV-burden communities in South Africa and Zambia engage with the concepts of "woman" and "HIV risk". The data are drawn from participatory storytelling activities completed with 604 participants across 78 group discussions between December 2012 and May 2013. During discussions we found that participants made use of the core archetypal caricatures of "goodness," "badness," and "vulnerability" when describing women's HIV risk. Community members shifted between these categories in their characterizations of women, as they acknowledged the multiple roles women play, internalized different stories about women, and sometimes shifted register in the same stories. Findings suggest that health implementers, in consultation with community members, should consider the multiple positions women occupy and how this impacts the wider community's understandings of women and "risk". This approach of taking on board community understandings of the complexity of HIV risk can inform the design and implementation of HIV prevention and care programs by rendering programs more focused and in-line with community needs.

ATTITUDES TOWARD SUICIDE: THE EFFECT OF SUICIDE DEATH IN THE FAMILY*

Zhang, Jie; Jia, Cun-Xian

2011-01-01

There have been few reports on the effect of suicide death on family members’ attitudes toward suicide. In order to estimate the extent to which suicide death affects attitudes toward suicide among family members of suicides, data of 264 informants from a case-control psychological autopsy study were analyzed. The results showed that there were no significant differences in attitudes toward suicide, measured by the General Social Survey’s (GSS) four questions, between informants of suicides and informants of living controls, between family members of suicides and family members of living controls, or between family members of suicides and non-family members of suicides. Our findings did not support the hypothesis that suicide death affects the attitudes toward suicide in suicides’ family members. However, some factors were found to be related to the pro-suicide attitudes measured by the four questions included in the GSS. PMID:20397616

Purpose Specific stressors associated with caregiving in Mexican-American (MA) families are not well documented, yet caregiving issues are paramount because informal care for parents is central to their culture. Although MA families who band together to provide care for one member are not unique, the literature does not describe the phenomenon of collective caregiving, which may be widespread but unrecognized. Such families are both understudied and poorly served by contemporary health systems because their characteristics are unknown. Design Descriptive, multi-site, longitudinal mixed-methods study of MA caregiving families. Findings We identified three types of collective caregivers: those providing care for multiple family members simultaneously; those providing care successively to several family members, and/or those finding themselves obliged to accept care during their caregiving of others. Discussion and Conclusions Collective caregiving of MA elders warrants further investigation. Implications for Practice Exploration of collective caregiving may provide a foundation for tailored family interventions. PMID:27389911

Following the detection of the rare DRD2 codon 311 variant (Ser{yields}Cys) in an affected member from a large, multiply affected panic disorder family, we investigated the occurrence of this variant in other family members. The variant occurred in both affected and unaffected individuals. Further screening in panic disorder sib pairs unrelated to this family failed to detect the Cys311 variant. Our data suggests that this variant has no pathogenic role in panic disorder. 18 refs., 1 fig.

How realistic is the international policy emphasis on schools 'substituting for families' of HIV/AIDS-affected children? We explore the ethic of care in Zimbabwean schools to highlight the poor fit between the western caring schools literature and daily realities of schools in different material and cultural contexts. Interviews and focus groups were conducted with 44 teachers and 55 community members, analysed in light of a companion study of HIV/AIDS-affected pupils' own accounts of their care-related experiences. We conceptualise schools as spaces of engagement between groups with diverse needs and interests (teachers, pupils and surrounding community members), with attention to the pathways through which extreme adversity impacts on those institutional contexts and social identifications central to giving and receiving care. Whilst teachers were aware of how they might support children, they seldom put these ideas into action. Multiple factors undermined caring teacher-pupil relationships in wider contexts of poverty and political uncertainty: loss of morale from low salaries and falling professional status; the inability of teachers to solve HIV/AIDS-related problems in their own lives; the role of stigma in deterring HIV/AIDS-affected children from disclosing their situations to teachers; authoritarian teacher-learner relations and harsh punishments fuelling pupil fear of teachers; and lack of trust in the wider community. These factors undermined: teacher confidence in their skills and capacity to support affected pupils and motivation to help children with complex problems; solidarity and common purpose amongst teachers, and between teachers and affected children; and effective bridging alliances between schools and their surrounding communities-all hallmarks of HIV-competent communities. We caution against ambitious policy expansions of teachers' roles without recognition of the personal and social costs of emotional labour, and the need for significant increases in resources and institutional recognition to enable teachers to adopt support roles. We highlight the need for research into how best to create opportunities for teacher recognition in deprived and disorganised institutional settings, and the development of more culturally appropriate notions of caring.

To estimate healthcare use and financial burden associated with heart disease among Indian households. Data from the 2004 round household survey of the National Sample Survey in India were used to assess the implications of heart disease for out-of-pocket health spending, spending on items other than health care, employment and healthcare financing patterns, by matching households with a member self-reporting heart disease (cardiovascular disease (CVD)-affected households) to (control) households with similar socio-economic and demographic characteristics. Propensity score matching methods were used. Compared with control households, CVD-affected households had more outpatient visits and inpatient stays, spent an extra INT$ (International Dollars) 232 (P < 0.01) per member on inpatient care annually, had lower non-medical spending (by INT$5 (P < 0.01) per member for a 15-day reference period), had a share of out-of-pocket health spending in total household expenditure that was 16.5% higher (P < 0.01) and relied more on borrowing and asset sales to finance inpatient care (32.7% vs. 12.8%, P < 0.01). Members of CVD-affected households had lower employment rates than members of control households (43.6% vs. 46.4%, P < 0.01), and elderly members experienced larger declines in employment than younger adults. CVD-affected households with lower socio-economic status were at heightened financial risk. Non-communicable conditions such as CVD can impose a serious economic burden on Indian households. © 2014 John Wiley & Sons Ltd.

2013-01-01

Terahertz (THz) radiation lies between the infrared and microwave regions of the electromagnetic spectrum and is non-ionizing. We show that exposure of artificial human skin tissue to intense, picosecond-duration THz pulses affects expression levels of numerous genes associated with non-melanoma skin cancers, psoriasis and atopic dermatitis. Genes affected by intense THz pulses include nearly half of the epidermal differentiation complex (EDC) members. EDC genes, which are mapped to the chromosomal human region 1q21, encode for proteins that partake in epidermal differentiation and are often overexpressed in conditions such as psoriasis and skin cancer. In nearly all the genes differentially expressed by exposure to intense THz pulses, the induced changes in transcription levels are opposite to disease-related changes. The ability of intense THz pulses to cause concerted favorable changes in the expression of multiple genes implicated in inflammatory skin diseases and skin cancers suggests potential therapeutic applications of intense THz pulses.

Completed Experiments in Human Adaptation: Roles for Social Science in Arctic Policy Development

Jensen, A. M.

2015-12-01

The Arctic contains many sites with exquisite organic preservation, which can be used to inform policy decisions in two very different ways. Archaeological sites can be considered at the result of completed experiments in human adaptation. With proper analysis of the multiple types of data they contain, one can see how climate change affected arctic ecosystems (including the human components) and how successful human responses were. Secondly, archaeological finds can provide vivid illustrations of the effects of climate change effects and extreme climatic events at a particular place. These illustrations appear to be far easier for members of the public to relate to than other means of transmitting scientific information, and can be good means of motivating people to be proactive.

2014-01-01

This study was designed to identify successful strategies used by investigators for working with their Institutional Review Boards (IRBs) in conducting human subjects research. Telephone interviews were conducted with 46 investigators representing nursing, medicine, and social work. Interview transcripts were analyzed using qualitative descriptive methods. Investigators emphasized the importance of intentionally cultivating positive relationships with IRB staff and members, and managing bureaucracy. A few used evasive measures to avoid conflict with IRBs. Few successful strategies were identified for working with multiple IRBs. Although most investigators developed successful methods for working with IRBs, further research is needed on how differences in IRB culture affect human subjects protection, and on best approaches to IRB approval of multi-site studies.

Multiple prostate cancer (PCa) risk-related loci have been discovered by genome-wide association studies (GWAS) based on case-control designs. However, GWAS findings may be confounded by population stratification if cases and controls are inadvertently drawn from different genetic backgrounds. In addition, since these loci were identified in cases with predominantly sporadic disease, little is known about their relationships with hereditary prostate cancer (HPC). The association between seventeen reported PCa susceptibility loci was evaluated with a family-based association test using 1,979 hereditary PCa families of European descent collected by members of the International Consortium for Prostate Cancer Genetics, with a total of 5,730 affected men. The risk alleles for 8 of the 17 loci were significantly over-transmitted from parents to affected offspring, including SNPs residing in 8q24 (regions 1, 2 and 3), 10q11, 11q13, 17q12 (region 1), 17q24 and Xp11. In subgroup analyses, three loci, at 8q24 (regions 1 and 2) plus 17q12, were significantly over-transmitted in hereditary PCa families with five or more affected members, while loci at 3p12, 8q24 (region 2), 11q13, 17q12 (region 1), 17q24 and Xp11 were significantly over-transmitted in HPC families with an average age of diagnosis at 65 years or less. Our results indicate that at least a subset of PCa risk-related loci identified by case-control GWAS are also associated with disease risk in HPC families.

Multiple prostate cancer (PCa) risk-related loci have been discovered by genome-wide association studies (GWAS) based on case–control designs. However, GWAS findings may be confounded by population stratification if cases and controls are inadvertently drawn from different genetic backgrounds. In addition, since these loci were identified in cases with predominantly sporadic disease, little is known about their relationships with hereditary prostate cancer (HPC). The association between seventeen reported PCa susceptibility loci was evaluated with a family-based association test using 1,979 hereditary PCa families of European descent collected by members of the International Consortium for Prostate Cancer Genetics, with a total of 5,730 affected men. The risk alleles for 8 of the 17 loci were significantly over-transmitted from parents to affected offspring, including SNPs residing in 8q24 (regions 1, 2 and 3), 10q11, 11q13, 17q12 (region 1), 17q24 and Xp11. In subgroup analyses, three loci, at 8q24 (regions 1 and 2) plus 17q12, were significantly over-transmitted in hereditary PCa families with five or more affected members, while loci at 3p12, 8q24 (region 2), 11q13, 17q12 (region 1), 17q24 and Xp11 were significantly over-transmitted in HPC families with an average age of diagnosis at 65 years or less. Our results indicate that at least a subset of PCa risk-related loci identified by case–control GWAS are also associated with disease risk in HPC families. PMID:22198737

Although a family history of thyroid cancer is one of the main risk factors for thyroid cancer, the benefit of screening individuals with a family history of thyroid cancer is not known. A prospective cohort study was performed with yearly screening using neck ultrasound and fine-needle aspiration biopsy of thyroid nodule(s) >0.5 cm in at-risk individuals whose relatives were diagnosed with familial non-medullary thyroid cancer (FNMTC). The eligibility criteria were the presence of thyroid cancer in two or more first-degree relatives and being older than seven years of age. Twenty-five kindred were enrolled in the study (12 families with two members affected, and 13 with three or more members affected at enrollment). Thyroid cancer was detected by screening in 4.6% (2/43) of at-risk individuals from families with two members affected, and in 22.7% (15/66) of at-risk members from families with three or more patients affected (p = 0.01). FNMTC detected by screening was characterized by a smaller tumor size (0.7 ± 0.5 cm vs. 1.5 ± 1.1 cm; p = 0.006), a lower rate of central neck lymph node metastases (17.6% vs. 51.1%; p = 0.02), less extensive surgery (hemithyroidectomy 23.5% vs. 0%; p = 0.002), and a lower rate of radioactive iodine therapy (23.5% vs. 79%; p < 0.001) compared to those affected at enrollment. Screening of at-risk family members resulted in earlier detection of low-risk FNMTC and was associated with a less aggressive initial treatment. Screening with thyroid ultrasound should be considered in kindred with three or more family members affected by FNMTC. Since active screening might be associated with the risk of overtreatment, it should be implemented with caution, specifically in elderly individuals.

The coping strategies, resilience and psychological distress of members of the Faculty of Forensic and Legal Medicine (FFLM) were measured in an attempt to establish how they are affected by, and accommodate potentially traumatic encounters with patients. Belief in a just world was also measured as it was deemed to be a mediating factor in the psychological distress exhibited in the medical practitioners who participated in this study. 120 members of the FFLM (65 females, 54 males and 1 undisclosed) volunteered to complete an online survey. Data was collected using Survey Monkey. Participants filled out the Personal Belief in a Just World Scale and General Belief in a Just World Scale, as well as the Connor-Davidson Resilience Scale 25, the COPE and the Brief Symptom Inventory. A multiple regression with stepwise entry was carried out. Personal belief in a just world, coping strategies and resilience were all identified as having a significant relationship with psychological distress. Although this is only a preliminary study into this phenomenon, findings suggest the personal belief in a just world, coping strategies and resilience are useful predictors of psychological distress amongst forensic medical practitioners. However they did not predict the majority of the variance and as such, more detailed investigations are needed to identify which other factors are important in order to design interventions and support for members of the Faculty of Forensic and Legal Medicine and other forensic medical practitioners.

Convective weather is known to be highly nonlinear and chaotic, and it is hard to predict their location and timing precisely. Our Big Data Assimilation (BDA) effort has been exploring to use dense and frequent observations to avoid non-Gaussian probability density function (PDF) and to apply an ensemble Kalman filter under the Gaussian error assumption. The phased array weather radar (PAWR) can observe a dense three-dimensional volume scan with 100-m range resolution and 100 elevation angles in only 30 seconds. The BDA system assimilates the PAWR reflectivity and Doppler velocity observations every 30 seconds into 100 ensemble members of storm-scale numerical weather prediction (NWP) model at 100-m grid spacing. The 30-second-update, 100-m-mesh BDA system has been quite successful in multiple case studies of local severe rainfall events. However, with 1000 ensemble members, the reduced-resolution BDA system at 1-km grid spacing showed significant non-Gaussian PDF with every-30-second updates. With a 10240-member ensemble Kalman filter with a global NWP model at 112-km grid spacing, we found roughly 1000 members satisfactory to capture the non-Gaussian error structures. With these in mind, we explore how the density of observations in space and time affects the non-Gaussianity in an ensemble Kalman filter with a simple toy model. In this presentation, we will present the most up-to-date results of the BDA research, as well as the investigation with the toy model on the non-Gaussianity with dense and frequent observations.

Building trusting relationships in online health communities.

2013-09-01

This study investigates consumers' use of online health communities (OHCs) for healthcare from a relationship building perspective based on the commitment-trust theory of relationships. The study proposes that perspective taking, empathic concern, self-efficacy, and network density affect the development of both cognitive and affective trust, which together determine OHC members' membership continuance intention (MCI) and knowledge contribution. Data collected from eight existing OHCs (N=255) were utilized to test the hypothesized model. Results show that perspective taking and self-efficacy can increase cognitive trust and affective trust, respectively. Network density contributes to cognitive and affective trust. Both cognitive trust and affective trust influence MCI, while only affective trust impacts members' knowledge contribution behaviors.

Autism spectrum disorders (ASD) have a high degree of heritability, but there is still much debate about specific causal genes and pathways. To gain insight into patterns of transmission, research has focused on the relatedness of quantitative autism traits (QAT) between family members, mostly using questionnaires. Yet, different kinds of bias may influence research results. In this paper, we focus on possible informant effects and, taking these into account, on possible intergenerational transmission of QAT. This study used multiple informant data retrieved via the Social Responsiveness Scale from 170 families with at least one member with ASD. Using intraclass correlations (ICCs) and mixed model analyses, we investigated inter-informant agreement and differences between parent and teacher reports on children and between self- and other-reports on adults. Using structural equation modelling (SEM), we investigated the relatedness of QAT between family members in ASD families. Parent-teacher agreement about social responsiveness was poor, especially for children with ASD, though agreement between parents was moderate to strong for affected and unaffected children. Agreement between self- and other-report in adult men was good, but only moderate in women. Agreement did not differ between adults with and without ASD. While accounting for informant effects, our SEM results corroborated the assortative mating theory and the intergenerational transmission of QAT from both fathers and mothers to their offspring.

Deficiencies in respiratory-chain complexes lead to a variety of clinical phenotypes resulting from inadequate energy production by the mitochondrial oxidative phosphorylation system. Defective expression of mtDNA-encoded genes, caused by mutations in either the mitochondrial or nuclear genome, represents a rapidly growing group of human disorders. By whole-exome sequencing, we identified two unrelated individuals carrying compound heterozygous variants in TRMT5 (tRNA methyltransferase 5). TRMT5 encodes a mitochondrial protein with strong homology to members of the class I-like methyltransferase superfamily. Both affected individuals presented with lactic acidosis and evidence of multiple mitochondrial respiratory-chain-complex deficiencies in skeletal muscle, although the clinical presentation of the two affected subjects was remarkably different; one presented in childhood with failure to thrive and hypertrophic cardiomyopathy, and the other was an adult with a life-long history of exercise intolerance. Mutations in TRMT5 were associated with the hypomodification of a guanosine residue at position 37 (G37) of mitochondrial tRNA; this hypomodification was particularly prominent in skeletal muscle. Deficiency of the G37 modification was also detected in human cells subjected to TRMT5 RNAi. The pathogenicity of the detected variants was further confirmed in a heterologous yeast model and by the rescue of the molecular phenotype after re-expression of wild-type TRMT5 cDNA in cells derived from the affected individuals. Our study highlights the importance of post-transcriptional modification of mitochondrial tRNAs for faithful mitochondrial function. Copyright © 2015 The Authors. Published by Elsevier Inc.

Biases on Initial Mass Function Determinations. II. Real Multiple Systems and Chance Superpositions

NASA Astrophysics Data System (ADS)

Maíz Apellániz, J.

2008-04-01

When calculating stellar initial mass functions (IMFs) for young clusters, one has to take into account that (1) most massive stars are born in multiple systems, (2) most IMFs are derived from data that cannot resolve such systems, and (3) multiple chance superpositions between members are expected to happen if the cluster is too distant. In this article I use numerical experiments to model the consequences of those phenomena on the observed color-magnitude diagrams and the IMFs derived from them. Real multiple systems affect the observed or apparent massive-star MF slope little but can create a significant population of apparently ultramassive stars. Chance superpositions produce only small biases when the number of superimposed stars is low but, once a certain number threshold is reached, they can affect both the observed slope and the apparent stellar upper mass limit. I apply these experiments to two well known massive young clusters in the Local Group, NGC 3603 and R136. In both cases I show that the observed population of stars with masses above 120 M⊙ can be explained by the effects of unresolved objects, mostly real multiple systems for NGC 3603 and a combination of real and chance-alignment multiple systems for R136. Therefore, the case for the reality of a stellar upper mass limit at solar or near-solar metallicities is strengthened, with a possible value even lower than 150 M⊙. An IMF slope somewhat flatter than Salpeter or Kroupa with γ between -1.6 and -2.0 is derived for the central region of NGC 3603, with a significant contribution to the uncertainty arising from the imprecise knowledge of the distance to the cluster. The IMF at the very center of R136 cannot be measured with the currently available data but the situation could change with new HST observations. This article is partially based on observations made with the NASA/ESA Hubble Space Telescope (HST), some of them associated with GO program 10602 and the rest gathered from the archive, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-26555.

Leader-member exchange and safety citizenship behavior: The mediating role of coworker trust.

PubMed

Jiang, Li; Li, Feng; Li, YongJuan; Li, Rui

2017-01-01

To achieve high safety levels, mere compliance with safety regulations is not sufficient; employees must be proactive and demonstrate safety citizenship behaviors. Trust is considered as a mechanism for facilitating the effects of a leader on employee citizenship behaviors. Increasingly research has focused on the role of trust in a safety context; however, the role of coworker trust has been overlooked. The mediating role of coworker trust in the relationship between the leader-member exchange and safety citizenship behavior is the focus of this field study. Front-line employees from an air traffic control center and an airline maintenance department completed surveys measuring leader-member exchange, co-worker trust, and safety citizenship behavior. Structural Equation Modeling revealed affective and cognitive trust in coworkers is influenced by leader-member exchange. A trust-based mediation model where cognitive trust and affective trust mediate the relationship between the leader-member exchange and safety citizenship behavior emerged. Results of this study add to our understanding of the relationship between leader-member exchange and safety behavior. The effect of co-worker trust and the extent to which employees participate in workplace safety practice were identified as critical factors. The findings show that managers need to focus on developing cognitive and affective coworker trust to improve safety citizenship behaviors.

Members of Glycosyl-Hydrolase Family 17 of A. fumigatus Differentially Affect Morphogenesis

PubMed Central

Millet, Nicolas; Latgé, Jean-Paul; Mouyna, Isabelle

2018-01-01

Cell wall biosynthesis and remodeling are essential for fungal growth and development. In the fungal pathogen Aspergillus fumigatus, the β(1,3)glucan is the major cell wall polysaccharide. This polymer is synthesized at the plasma membrane by a transmembrane complex, then released into the parietal space to be remodeled by enzymes, and finally incorporated into the pre-existing cell wall. In the Glycosyl-Hydrolases family 17 (GH17) of A. fumigatus, two β(1,3)glucanosyltransferases, Bgt1p and Bgt2p, have been previously characterized. Disruption of BGT1 and BGT2 did not result in a phenotype, but sequence comparison and hydrophobic cluster analysis showed that three other genes in A. fumigatus belong to the GH17 family, SCW4, SCW11, and BGT3. In constrast to Δbgt1bgt2 mutants, single and multiple deletion of SCW4, SCW11, and BGT3 showed a decrease in conidiation associated with a higher conidial mortality and an abnormal conidial shape. Moreover, mycelium was also affected with a slower growth, stronger sensitivity to cell wall disturbing agents, and altered cell wall composition. Finally, the synthetic interactions between Bgt1p, Bgt2p, and the three other members, which support a functional cooperation in cell-wall assembly, were analyzed. Our data suggest that Scw4p, Scw11p, and Bgt3p are essential for cell wall integrity and might have antagonistic and distinct functions to Bgt1p and Bgt2p. PMID:29385695

Individuals with a history of traumatic brain injury (TBI) may have chronic problems with irritability, which can negatively affect their lives. (1) To describe the experience (thoughts and feelings) of irritability from the perspectives of multiple people living with or affected by the problem, and (2) to develop a conceptual model of irritability. Qualitative, participatory research. Forty-four stakeholders (individuals with a history of TBI, family members, community professionals, healthcare providers, and researchers) divided into 5 focus groups. Each group met 10 times to discuss the experience of irritability following TBI. Data were coded using grounded theory to develop themes, metacodes, and theories. Not applicable. A conceptual model emerged in which irritability has 5 dimensions: affective (related to moods and feelings); behavioral (especially in areas of self-regulation, impulse control, and time management); cognitive-perceptual (self-talk and ways of seeing the world); relational issues (interpersonal and family dynamics); and environmental (including environmental stimuli, change, disruptions in routine, and cultural expectations). This multidimensional model provides a framework for assessment, treatment, and future research aimed at better understanding irritability, as well as the development of assessment tools and treatment interventions.

Background Tumoral calcinosis is an autosomal recessive disorder characterized by ectopic calcification and hyperphosphatemia. Methods We describe a family with tumoral calcinosis requiring amputations. The predominant metabolic anomaly identified in three affected family members was hyperphosphatemia. Biochemical and phenotypic analysis of 13 kindred members, together with exome analysis of 6 members, was performed. Results We identified a novel Q67K mutation in fibroblast growth factor 23 (FGF23), segregating with a null (deletion) allele on the other FGF23 homologue in three affected members. Affected siblings had high circulating plasma C-terminal FGF23 levels, but undetectable intact FGF23 or N-terminal FGF23, leading to loss of FGF23 function. Conclusions This suggests that in human, as in experimental models, severe prolonged hyperphosphatemia may be sufficient to produce bone differentiation proteins in vascular cells, and vascular calcification severe enough to require amputation. Genetic modifiers may contribute to the phenotypic variation within and between families. PMID:25378588

The influence of mood on the perception of hearing-loss related quality of life in people with hearing loss and their significant others.

PubMed

Preminger, Jill E; Meeks, Suzanne

2010-04-01

The purpose of this research was to investigate the congruent/incongruent perceptions of hearing-loss related quality of life between members of couples and to determine how incongruence was affected by individual psychosocial characteristics, specifically measures of mood (negative affect and positive affect), stress, and communication in the marriage. An exploratory correlational analysis was performed on data for 52 couples in which only one member had a hearing loss. In the regression analyses the independent variables were hearing-loss related quality of life scores measured in people with hearing loss, measured in significant others, and differences in hearing-loss related quality of life among members of a couple. The results demonstrate that both in people with hearing loss and their significant others, perceptions of hearing-loss related quality of life is highly correlated with negative mood scores. Incongruence in hearing-loss related quality of life scores reported by members of a couple were highly correlated with negative affect measured within each individual. Future research evaluating the effectiveness of audiologic rehabilitation can use measures of mood as an outcome variable.

A specific cognitive deficit within semantic cognition across a multi-generational family

PubMed Central

Briscoe, Josie; Chilvers, Rebecca; Baldeweg, Torsten; Skuse, David

2012-01-01

We report a study of eight members of a single family (aged 8–72 years), who all show a specific deficit in linking semantic knowledge to language. All affected members of the family had high levels of overall intelligence; however, they had profound difficulties in prose and sentence recall, listening comprehension and naming. The behavioural deficit was remarkably consistent across affected family members. Structural neuroimaging data revealed grey matter abnormalities in the left infero-temporal cortex and fusiform gyri: brain areas that have been associated with integrative semantics. This family demonstrates, to our knowledge, the first example of a heritable, highly specific abnormality affecting the interface between language and cognition in humans and has important implications for our understanding of the genetic basis of cognition.

"This Is a Partnership Between All of Us": Audiologists' Perceptions of Family Member Involvement in Hearing Rehabilitation.

PubMed

Meyer, Carly; Scarinci, Nerina; Ryan, Brooke; Hickson, Louise

2015-12-01

The purpose of the study was to explore the perceptions of audiologists about the role of family members in hearing rehabilitation for older adults with hearing impairment (HI), the influence of family member involvement on outcomes, and factors affecting family members' involvement. A qualitative descriptive research study was undertaken. Using a purposeful sampling strategy, 9 audiologists were recruited. Audiologists participated in individual semistructured interviews. Interview transcripts were analyzed using thematic analysis, and a process of member checking was used to enhance the trustworthiness of findings reported. The importance of promoting partnership emerged as the overarching theme. Audiologists valued promoting partnership with family members so that a shared understanding could be established, family members could be active participants with distinct roles in hearing rehabilitation, and the rehabilitation outcomes for the person with HI could be improved. Audiologists generally reported low attendance rates of family members to appointments and identified 5 major factors affecting family participation. There is growing recognition among audiologists of the importance of promoting partnership with family members during the hearing rehabilitation process. More research is needed to develop and evaluate a family-centered model of hearing health care that considers the service-level barriers identified by audiologists in the present study.

Can we beat the biotin-avidin pair?: cucurbit[7]uril-based ultrahigh affinity host-guest complexes and their applications.

2015-12-07

The design of synthetic, monovalent host-guest molecular recognition pairs is still challenging and of particular interest to inquire into the limits of the affinity that can be achieved with designed systems. In this regard, cucurbit[7]uril (CB[7]), an important member of the host family cucurbit[n]uril (CB[n], n = 5-8, 10, 14), has attracted much attention because of its ability to form ultra-stable complexes with multiple guests. The strong hydrophobic effect between the host cavity and guests, ion-dipole and dipole-dipole interactions of guests with CB portals helps in cooperative and multiple noncovalent interactions that are essential for realizing such strong complexations. These highly selective, strong yet dynamic interactions can be exploited in many applications including affinity chromatography, biomolecule immobilization, protein isolation, biological catalysis, and sensor technologies. In this review, we summarize the progress in the development of high affinity guests for CB[7], factors affecting the stability of complexes, theoretical insights, and the utility of these high affinity pairs in different challenging applications.

Living on the wedge: female control of paternity in a cooperatively polyandrous cichlid

Theories suggest that, in cooperatively breeding species, female control over paternity and reproductive output may affect male reproductive skew and group stability. Female paternity control may come about through cryptic female choice or female reproductive behaviour, but experimental studies are scarce. Here, we show a new form of female paternity control in a cooperatively polyandrous cichlid fish (Julidochromis transcriptus), in which females prefer wedge-shaped nesting sites. Wedge-shaped sites allowed females to manipulate the siring success of the group member males by spawning the clutch at the spot where the large males were just able to enter and fertilize the outer part of the clutch. Small males fertilized the inner part of the clutch, protected from the large aggressive males, leading to low male reproductive skew. Small males provided more brood care than large males. Multiple paternity induced both males to provide brood care and reduced female brood care accordingly. This is, to our knowledge, the first documented case in a species with external fertilization showing female mating behaviour leading to multiple male paternity and increased male brood care as a result.

What Can We Learn from Rodents about Prolactin in Humans?

PubMed Central

Ben-Jonathan, Nira; LaPensee, Christopher R.; LaPensee, Elizabeth W.

2008-01-01

Prolactin (PRL) is a 23-kDa protein hormone that binds to a single-span membrane receptor, a member of the cytokine receptor superfamily, and exerts its action via several interacting signaling pathways. PRL is a multifunctional hormone that affects multiple reproductive and metabolic functions and is also involved in tumorigenicity. In addition to being a classical pituitary hormone, PRL in humans is produced by many tissues throughout the body where it acts as a cytokine. The objective of this review is to compare and contrast multiple aspects of PRL, from structure to regulation, and from physiology to pathology in rats, mice, and humans. At each juncture, questions are raised whether, or to what extent, data from rodents are relevant to PRL homeostasis in humans. Most current knowledge on PRL has been obtained from studies with rats and, more recently, from the use of transgenic mice. Although this information is indispensable for understanding PRL in human health and disease, there is sufficient disparity in the control of the production, distribution, and physiological functions of PRL among these species to warrant careful and judicial extrapolation to humans.

Ensemble Data Mining Methods

NASA Technical Reports Server (NTRS)

Oza, Nikunj C.

2004-01-01

Ensemble Data Mining Methods, also known as Committee Methods or Model Combiners, are machine learning methods that leverage the power of multiple models to achieve better prediction accuracy than any of the individual models could on their own. The basic goal when designing an ensemble is the same as when establishing a committee of people: each member of the committee should be as competent as possible, but the members should be complementary to one another. If the members are not complementary, Le., if they always agree, then the committee is unnecessary---any one member is sufficient. If the members are complementary, then when one or a few members make an error, the probability is high that the remaining members can correct this error. Research in ensemble methods has largely revolved around designing ensembles consisting of competent yet complementary models.

Assessing uncertainty and sensitivity of model parameterizations and parameters in WRF affecting simulated surface fluxes and land-atmosphere coupling over the Amazon region

This study aims to quantify the relative importance and uncertainties of different physical processes and parameters in affecting simulated surface fluxes and land-atmosphere coupling strength over the Amazon region. We used two-legged coupling metrics, which include both terrestrial (soil moisture to surface fluxes) and atmospheric (surface fluxes to atmospheric state or precipitation) legs, to diagnose the land-atmosphere interaction and coupling strength. Observations made using the Department of Energy's Atmospheric Radiation Measurement (ARM) Mobile Facility during the GoAmazon field campaign together with satellite and reanalysis data are used to evaluate model performance. To quantify the uncertainty in physical parameterizations, we performed a 120 member ensemble of simulations with the WRF model using a stratified experimental design including 6 cloud microphysics, 3 convection, 6 PBL and surface layer, and 3 land surface schemes. A multiple-way analysis of variance approach is used to quantitatively analyze the inter- and intra-group (scheme) means and variances. To quantify parameter sensitivity, we conducted an additional 256 WRF simulations in which an efficient sampling algorithm is used to explore the multiple-dimensional parameter space. Three uncertainty quantification approaches are applied for sensitivity analysis (SA) of multiple variables of interest to 20 selected parameters in YSU PBL and MM5 surface layer schemes. Results show consistent parameter sensitivity across different SA methods. We found that 5 out of 20 parameters contribute more than 90% total variance, and first-order effects dominate comparing to the interaction effects. Results of this uncertainty quantification study serve as guidance for better understanding the roles of different physical processes in land-atmosphere interactions, quantifying model uncertainties from various sources such as physical processes, parameters and structural errors, and providing insights for improving the model physics parameterizations.

Members of the plant NUCLEAR FACTOR Y (NF-Y) family are composed of the NF-YA, NF-YB, and NF-YC subunits. In Brassica napus (canola), each of these subunits forms a multimember subfamily. Plant NF-Ys were reported to be involved in several abiotic stresses. In this study, we demonstrated that multiple members of thirty three BnNF-Ys responded rapidly to salinity, drought, or ABA treatments. Transcripts of five BnNF-YAs, seven BnNF-YBs, and two BnNF-YCs were up-regulated by salinity stress, whereas the expression of thirteen BnNF-YAs, ten BnNF-YBs, and four BnNF-YCs were induced by drought stress. Under NaCl treatments, the expression of one BnNF-YA10 and four NF-YBs (BnNF-YB3, BnNF-YB7, BnNF-YB10, and BnNF-YB14) were greatly increased. Under PEG treatments, the expression levels of four NF-YAs (BnNF-YA9, BnNF-YA10, BnNF-YA11, and BnNF-YA12) and five NF-YBs (BnNF-YB1, BnNF-YB8, BnNF-YB10, BnNF-YB13, and BnNF-YB14) were greatly induced. The expression profiles of 20 of the 27 salinity- or drought-induced BnNF-Ys were also affected by ABA treatment. The expression levels of six NF-YAs (BnNF-YA1, BnNF-YA7, BnNF-YA8, BnNF-YA9, BnNF-YA10, and BnNF-YA12) and seven BnNF-YB members (BnNF-YB2, BnNF-YB3, BnNF-YB7, BnNF-YB10, BnNF-YB11, BnNF-YB13, and BnNF-YB14) and two NF-YC members (BnNF-YC2 and BnNF-YC3) were greatly up-regulated by ABA treatments. Only a few BnNF-Ys were inhibited by the above three treatments. Several NF-Y subfamily members exhibited collinear expression patterns. The promoters of all stress-responsive BnNF-Ys harbored at least two types of stress-related cis-elements, such as ABRE, DRE, MYB, or MYC. The cis-element organization of BnNF-Ys was similar to that of Arabidopsis thaliana, and the promoter regions exhibited higher levels of nucleotide sequence identity with Brassica rapa than with Brassica oleracea. This work represents an entry point for investigating the roles of canola NF-Y proteins during abiotic stress responses and provides insight into the genetic evolution of Brassica NF-Ys.

cdc-25.2, a C. elegans ortholog of cdc25, is required to promote oocyte maturation.

Cdc25 is an evolutionarily conserved protein phosphatase that promotes progression through the cell cycle. Some metazoans have multiple isoforms of Cdc25, which have distinct functions and different expression patterns during development. C. elegans has four cdc-25 genes. cdc-25.1 is required for germline mitotic proliferation. To determine if the other members of the cdc-25 family also contribute to regulation of cell division in the germ line, we examined phenotypes of loss-of-function mutants of the other cdc-25 family genes. We found that cdc-25.2 is also essential for germline development. cdc-25.2 homozygous mutant hermaphrodites exhibited sterility as a result of defects in oogenesis: mutant oocytes were arrested as endomitotic oocytes that were not fertilized successfully. Spermatogenesis and male germline development were not affected. Through genetic interaction studies, we found that CDC-25.2 functions upstream of maturation-promoting factor containing CDK-1 and CYB-3 to promote oocyte maturation by counteracting function of WEE-1.3. We propose that cdc-25 family members function as distinct but related cell cycle regulators to control diverse cell cycles in C. elegans germline development.

We describe a pedigree presenting X-linked severe mental retardation associated with multiple congenital abnormalities and 46,XY gonadal dysgenesis, leading in one family member to female gender assignment. Female carriers are unaffected. The dysmorphic features are similar to those described in the {alpha}-thalassemia and mental retardation (ATR-X) syndrome, although there is no clinical evidence of {alpha}-thalassemia in this family. In addition, the family had other clinical features not previously observed in the ATR-X syndrome, including partial optic-nerve atrophy and partial ocular albinism. Mutations in a putative DNA helicase, termed XH2, have been reported to give rise to the ATR-X syndrome. Wemore » screened the YCH2 gene for mutations in affected members of the family and identified a 4-bp deletion at an intron/exon boundary that removes an invariant 3{prime} splice-acceptor site. The mutation cosegregates with the syndrome. The genomic deletion causes missplicing of the pre-mRNA, which results in the loss of 8 bp of coding sequence, thereby generating a frameshift and a downstream premature stop codon. Our finding increases the range of clinical features associated with mutations in the XH2 gene. 17 refs., 4 figs., 2 tabs.« less

When standards are wide of the mark: nonselective superiority and inferiority biases in comparative judgments of objects and concepts.

PubMed

Giladi, Eilath E; Klar, Yechiel

2002-12-01

People are frequently required to judge how particular group members measure up against others in their group. According to the local-comparisons-general-standards (LOGE) approach, in these member-to-group comparisons, people fail to use the normatively appropriate local (group) standard and are infelicitously affected by a more general standard (involving instances from outside the judged group). Within positive groups, target group members are judged superior to the other members of the group, and within negative groups, inferior. To date, these nonselective superiority and inferiority biases have been demonstrated solely in judgments about human beings. In 6 experiments, nonselective biases were found in perceptual, affective, and cognitive judgments of nonhuman targets, objects, and concepts, thus supporting a cognitive rather than a social account.

The let-7 family contains 12 members, which share identical seed regions, suggesting that they may target the same mRNAs. It is essential to develop a means that can regulate the functions of all members. Using a DNA synthesis technique, we have generated an anti-let-7 sponge aiming to modulate the function of all members. We found that products of the anti-let-7 construct could bind and inactivate all members of the let-7 family, producing decoy and decay effects. To test the role of the anti-let-7 sponge, we stably expressed the anti-let-7 construct in two types of cells, the breast carcinoma cells MT-1 and the oldest and most commonly used human cervical cancer cell line, HeLa cells. We found that expression of anti-let-7 increased cell survival, invasion and adhesion, which corroborate with known functions of let-7 family members. We further identified a novel target site across all species of the let-7 family in hyaluronan synthase 2 (HAS2). HAS2 overexpression produced similar effects as the anti-let-7 sponge. Silencing HAS2 expression by siRNAs produced opposite effects to anti-let-7 on cell survival and invasion. The ability of anti-let-7 to regulate multiple members of the let-7 family allows us to observe their multiple functions using a single reagent. This approach can be applied to other family members with conserved sequences. PMID:22871741

This study evaluates the role of older family members as providers of social resources within familial network systems affected by an inherited cancer susceptibility syndrome.  Respondents who previously participated in a study that involved genetic counseling and testing for Lynch syndrome and their family network members were invited to participate in a onetime telephone interview about family communication. A total of 206 respondents from 33 families identified 2,051 social relationships (dyads). Nineteen percent of the respondents and 25% of the network members were older (≥60 years). Younger respondents (≤59 years) were more likely to nominate older network members as providers of social resources than younger members: instrumental support (odds ratio [OR] = 1.68), emotional support (OR = 1.71), help in crisis situation (OR = 2.04), and dependability when needed (OR = 2.15). Compared with younger network members, older members were more likely to be listed as encouragers of colon cancer screening by both younger (OR = 3.40) and older respondents (OR = 1.90) independent of whether support exchange occurred in the relationship. Engaging older network members in health interventions to facilitate screening behaviors and emotional well-being of younger members within families affected by inherited conditions may be beneficial. Findings can be used to empower older individuals about their important social roles in enhancing the well-being of their family members and to inform younger individuals about their older relatives' resourcefulness to facilitate positive social interactions.

1) To explore family members' lived experiences of driving disruption at early and later stages of the recovery continuum following acquired brain injury (ABI). 2) To describe health-related quality of life of family members of individuals with ABI who are experiencing driving disruption. Mixed methods phenomenological research approach. Semi-structured interviews and health-related quality of life questionnaires were conducted with 15 family members of individuals with ABI (early group: 1-12 months post-injury, n = 6; later group: >1 year post-injury, n = 9). Two main themes were identified: Different for everyone: how driving disruption affects families, and Making it harder: context of driving disruption. The challenges of driving disruption were reported more frequently and with a more intense focus by family members who were caring for their relative for more than 1 year post-injury. This group also reported higher caregiver strain and poorer health-related quality of life. Reduced satisfaction with life, poor mental health and affected family functioning were reported by both groups. Driving disruption impacts on family members and has long-lasting consequences. It is important for clinicians to work with family members to manage these challenges even years after ABI and consider individual contextual factors.

Medical Decision Making for Patients Without Proxies: The Effect of Personal Experience in the Deliberative Process.

PubMed

Robichaud, Allyson L

2015-01-01

The number of admissions to hospitals of patients without a proxy decision maker is rising. Very often these patients need fairly immediate medical intervention for which informed consent--or informed refusal--is required. Many have recommended that there be a process in place to make these decisions, and that it include a variety of perspectives. People are particularly wary of relying solely on medical staff to make these decisions. The University Hospitals Case Medical Center recruits community members from its Ethics Committee to serve on a subcommittee, the Patients Without Proxies (PWP) Committee, which works with medical staff during the decision-making process for these patients. Generally, the community members go to the bedside to observe patients. This article looks at how those unused to observing hospitalized patients who are sick and/or dying are affected, comparing them to mock jurors in a research study who are exposed to graphic photographs related to a fabricated crime scene. Judgments made by the mock jurors are affected by viewing such images. The personal experience of witnessing unfamiliar and shocking scenes affects their subsequent judgments. While it may be difficult to tease out whether observing patients causes PWP members to be benefited or harmed, they are affected by what they see. If a variety of perspectives is desirable to reduce possible bias or error, this article argues that at least one community member should refrain from seeing the patient in order to add a different and valuable voice to the decision-making process. Members of the subcommittee base their judgments on the various kinds of information available. Sometimes the things they see, hear, or feel may affect them particularly deeply, and affect their judgments as well. In this article I explore the idea that something like this may be happening in a particular kind of clinical ethics case consultation. Copyright 2015 The Journal of Clinical Ethics.

A medical home: value and implications of knowledge management.

Central to the "medical home" concept is the premise that the delivery of effective primary care requires a fundamental shift in relationships among practice members and between practice members and patients. Primary care practices can potentially increase their capacity to deliver effective care through knowledge management (KM), a process of sharing and making existing knowledge available or by developing new knowledge among practice members and patients. KM affects performance by influencing work relationships to enhance learning, decision making, and task execution. We extend our previous work to further characterize, describe, and contrast how primary care practices exhibit KM and explain why KM deserves attention in medical home redesign initiatives. Case studies were conducted, drawn from two higher and lower performing practices, which were purposely selected based on disease management, prevention, and productivity measures from an improvement trial. Observations of operations, clinical encounters, meetings, and interviews with office members and patients were transcribed and coded independently using a KM template developed from a previous secondary analysis. Face-to-face discussions resolved coding differences among research team members. Confirmation of findings was sought from practice participants. Practices manifested varying degrees of KM effectiveness through six interdependent processes and multiple overlapping tools. Social tools, such as face-to-face-communication for sharing and developing knowledge, were often more effective than were expensive technical tools such as an electronic medical record. Tool use was tailored for specific outcomes, interacted with each other, and leveraged by other organizational capacities. Practices with effective KM were more open to adopting and sustaining new ways of functioning, ways reflecting attributes of a medical home. Knowledge management differences occur within and between practices and can explain differences in performance. By relying more on social tools rather than costly, high-tech investment, KM leverages primary care's relationship-centered strength, facilitating practice redesign as a medical home.

About 37 genes have been reported to be involved in autosomal recessive retinitis pigmentosa, a hereditary retinal disease. However, causative genes remain unclear in a lot of cases. Two sibs of a Chinese family with ocular disease were diagnosed in Eye and ENT Hospital of Fudan University. Targeted sequencing performed on proband to screen pathogenic mutations. PCR combined Sanger sequencing then performed on eight family members including two affected and six unaffected individuals to determine whether mutations cosegregate with disease. Two affected members exhibited clinical features that fit the criteria of autosomal recessive retinitis pigmentosa. Two heterozygous mutations (NM000087, p.Y82X and p.L89fs) in CNGA1 were revealed on proband. Affected members were compound heterozygotes for the two mutations whereas unaffected members either had no mutation or were heterozygote carriers for only one of the two mutations. That is, these mutations cosegregate with autosomal recessive retinitis pigmentosa. Compound heterozygous mutations (NM000087, p.Y82X and p.L89fs) in exon 6 of CNGA1are pathogenic mutations in this Chinese family. Of which, p.Y82X is firstly reported in patient with autosomal recessive retinitis pigmentosa.

2009-03-01

A proper understanding of patterns of care represents a crucial step in improving clinical decision making and enhancing service provision. Only a few studies, however, have explored global patterns of psychiatric admissions nationwide, and none have been undertaken in Italy. Sociodemographic, clinical and treatment-related information was collected for 1577 patients admitted to 130 public and 36 private in-patient facilities in Italy during an index period in the year 2004. All patients were also rated using the 24-item Brief Psychiatric Rating Scale (BPRS) and the Personal and Social Performance (PSP) rating scales. Non-affective psychoses (36%) were the most common diagnoses and accounted to a large extent for compulsory admissions. Private facilities were more likely to admit patients with organic mental disorders and substance abuse/dependence and less likely to admit patients with non-affective psychoses. Overall, 77.8% of patients had been receiving treatment by a mental health professional in the month prior to admission. In 54% of cases, the admission was solicited by patients' family members. The main factors preceding admission were impairment in work or social functioning, social withdrawal, and conflict with family members. Agitation, delusions and/or hallucinations, and the presence of multiple problems were associated with compulsory admissions, whereas depressive and anxiety symptoms were associated with voluntary admissions. In a mixed, public-private psychiatric care system, like the Italian one, public and private facilities admit patients with widely different clinical characteristics and needs. Family support represents an important resource for most patients, and interventions specifically addressed to relieving family burden are warranted.

The effect of excluding juveniles on apparent adult olive baboons (Papio anubis) social networks

Fedurek, Piotr; Lehmann, Julia

2017-01-01

In recent years there has been much interest in investigating the social structure of group living animals using social network analysis. Many studies so far have focused on the social networks of adults, often excluding younger, immature group members. This potentially may lead to a biased view of group social structure as multiple recent studies have shown that younger group members can significantly contribute to group structure. As proof of the concept, we address this issue by investigating social network structure with and without juveniles in wild olive baboons (Papio anubis) at Gashaka Gumti National Park, Nigeria. Two social networks including all independently moving individuals (i.e., excluding dependent juveniles) were created based on aggressive and grooming behaviour. We used knockout simulations based on the random removal of individuals from the network in order to investigate to what extent the exclusion of juveniles affects the resulting network structure and our interpretation of age-sex specific social roles. We found that juvenile social patterns differed from those of adults and that the exclusion of juveniles from the network significantly altered the resulting overall network structure. Moreover, the removal of juveniles from the network affected individuals in specific age-sex classes differently: for example, including juveniles in the grooming network increased network centrality of adult females while decreasing centrality of adult males. These results suggest that excluding juveniles from the analysis may not only result in a distorted picture of the overall social structure but also may mask some of the social roles of individuals belonging to different age-sex classes.

To improve the quality of admissions interviews for a doctor of pharmacy program, using a multiple mini-interview (MMI) in place of the standard interview. Stakeholders completed an anonymous web-based survey. This study characterized perceptions of the MMI format across 3 major stakeholders (candidates, interviewers, admissions committee members) and included comparative cost estimates.Costs were estimated using human and facility resources from the 2012 cycle (standard format) and the 2013 cycle (MMI format). Most candidates (65%), interviewers (86%), and admissions committee members (79%) perceived the MMI format as effective for evaluating applicants, and most (59% of candidates, 84% of interviewers, 77% of committee members) agreed that the MMI format should be continued. Cost per candidate interviewed was $136.34 (standard interview) vs $75.30 (MMI). Perceptions of the MMI process were favorable across stakeholder groups, and this format was less costly per candidate interviewed.

To test whether the combination of number and location of distant metastases affects cancer-specific survival in patients with metastatic renal cell carcinoma. Overall, 242 metastatic renal cell carcinoma patients with synchronous metastases at diagnosis underwent cytoreductive nephrectomy at a single institution. Combinations of number and location of distant metastases were coded as: single metastasis and single organ affected, multiple metastases and single organ affected, single metastasis for each of the multiple organs affected, and multiple metastases for each of the multiple organs affected. Covariates included age, symptoms, performance status, American Society of Anesthesiologists score, hemoglobin, lactate dehydrogenase, tumor size, Fuhrman grade, T stage, lymph node status, necrosis, sarcomatoid features and metastasectomy at the time of nephrectomy. The median survival was 34.7 versus 32.3 versus 29.6 versus 8.5 months for single metastasis and single organ affected, multiple metastases and single organ affected single metastasis for each of the multiple organs affected, and multiple metastases for each of the multiple organs affected patients, respectively. At multivariable analyses, the combination of number and location of distant metastases resulted in one of the most informative and independent predictors of cancer-specific survival in metastatic renal cell carcinoma patients. The lung was the location with the highest rate of single organ affected (50.3% vs 35.1% in other sites; P < 0.001). Considering only patients with a single metastasis, no statistically significantly different cancer-specific survival rates were recorded (P > 0.3) among different metastatic organs. Among metastatic renal cell carcinoma patients undergoing cytoreductive nephrectomy, the combination of the number and location of distant metastases is a major independent predictor of cancer-specific survival. Patients with multiple organs affected by multifocal disease are more likely to have poorer survival. © 2012 The Japanese Urological Association.

The life cycle of chondrocytes in the developing skeleton

PubMed Central

Shum, Lillian; Nuckolls, Glen

2002-01-01

Cartilage serves multiple functions in the developing embryo and in postnatal life. Genetic mutations affecting cartilage development are relatively common and lead to skeletal malformations, dysfunction or increased susceptibility to disease or injury. Characterization of these mutations and investigation of the molecular pathways in which these genes function have contributed to an understanding of the mechanisms regulating skeletal patterning, chondrogenesis, endochondral ossification and joint formation. Extracellular growth and differentiation factors including bone morphogenetic proteins, fibroblast growth factors, parathyroid hormone-related peptide, extracellular matrix components, and members of the hedgehog and Wnt families provide important signals for the regulation of cell proliferation, differentiation and apoptosis. Transduction of these signals within the developing mesenchymal cells and chondrocytes results in changes in gene expression mediated by transcription factors including Smads, Msx2, Sox9, signal transducer and activator of transcription (STAT), and core-binding factor alpha 1. Further investigation of the interactions of these signaling pathways will contribute to an understanding of cartilage growth and development, and will allow for the development of strategies for the early detection, prevention and treatment of diseases and disorders affecting the skeleton.

The Williams–Beuren syndrome (WBS) region at 7q11.23 is subject to several genomic rearrangements, one of which, the WBSinv-1 variant, is an inversion polymorphism. The WBSinv-1 chromosome has been shown to occur frequently in parents of individuals with WBS, implying that it predisposes the region to the WBS deletion. Here we investigate two WBS families with multiple affected children, and show that in one family, both siblings have a deletion on a WBSinv-1 chromosome background that arose due to interchromosomal recombination. These results suggest that the two WBS deletions in this family were independent events, and that there is likely a significant increase in the risk of deletion of the WBS region associated with the WBSinv-1 chromosome. The rarity of multiplex WBS families would suggest that the overall risk of having a child with WBS is still relatively low; however, families with an existing member with WBS may choose to opt for WBSinv-1 testing and genetic counseling.

2018-03-05

The cyclic 3',5'-adenosine monophosphate (cAMP) was the first among the so-called "second messengers" to be described. It is conserved in most organisms and functions as a signal transducer by mediating the intracellular effects of multiple hormones and neurotransmitters. In this review, we first delineate how different members of the cAMP pathway ensure its correct compartmentalization and activity, mediate the terminal intracellular effects, and allow the crosstalk with other signaling pathways. We then focus on the pituitary gland, where cAMP exerts a crucial function by controlling the responsiveness of the cells to hypothalamic hormones, neurotransmitters and peripheral factors. We discuss the most relevant physiological functions mediated by cAMP in the different pituitary cell types, and summarize the defects affecting this pathway that have been reported in the literature. We finally discuss how a deregulated cAMP pathway is involved in the pathogenesis of pituitary disorders and how it affects the response to therapy. Copyright © 2017. Published by Elsevier B.V.

Managing patients whose family members are physicians.

PubMed

Bramstedt, K A; Popovich, M

2012-01-01

The ethical complexities involving physicians who treat their own family members are well known and it is generally accepted that such practice should not occur. We present three anonymous cases in which patient family members who worked as physicians complicated the medical care of their hospitalized relatives. When a health care worker's family member becomes a hospital patient, the situation can be emotionally charged due to the medical insight the multiple parties have, as well as the desire of relatives to be protective of their family members.

Recurrent mutations in the splicing factor SRSF2 are associated with poor clinical outcomes in myelodysplastic syndromes (MDS). Their high frequency suggests these mutations drive oncogenesis, yet the molecular explanation for this process is unclear. SRSF2 mutations could directly affect pre-mRNA splicing of a vital gene product; alternatively, a whole network of gene products could be affected. Here we determine how SRSF2 mutations globally affect RNA binding and splicing in vivo using HITS-CLIP. Remarkably, the majority of differential binding events do not translate into alternative splicing of exons with SRSF2 P95H binding sites. Alternative splice alterations appear to be dominated by indirect effects. Importantly, SRSF2 P95H targets are enriched in RNA processing and splicing genes, including several members of the hnRNP and SR families of proteins, suggesting a "splicing-cascade" phenotype wherein mutation of a single splicing factor leads to widespread modifications in multiple RNA processing and splicing proteins. We show that splice alteration of HNRNPA2B1, a splicing factor differentially bound and spliced by SRSF2 P95H , impairs hematopoietic differentiation in vivo. Our data suggests a model whereby the recurrent mutations in splicing factors set off a cascade of gene regulatory events that together affect hematopoiesis and drive cancer.

PurposeTo evaluate the cost-effectiveness of BRCA testing in women with breast cancer, and cascade testing in family members of BRCA mutation carriers.MethodsA cost-effectiveness analysis was conducted using a cohort Markov model from a health-payer perspective. The model estimated the long-term benefits and costs of testing women with breast cancer who had at least a 10% pretest BRCA mutation probability, and the cascade testing of first- and second-degree relatives of women who test positive.ResultsCompared with no testing, BRCA testing of affected women resulted in an incremental cost per quality-adjusted life-year (QALY) gained of AU$18,900 (incremental cost AU$1,880; incremental QALY gain 0.10) with reductions of 0.04 breast and 0.01 ovarian cancer events. Testing affected women and cascade testing of family members resulted in an incremental cost per QALY gained of AU$9,500 compared with testing affected women only (incremental cost AU$665; incremental QALY gain 0.07) with additional reductions of 0.06 breast and 0.01 ovarian cancer events.ConclusionBRCA testing in women with breast cancer is cost-effective and is associated with reduced risk of cancer and improved survival. Extending testing to cover family members of affected women who test positive improves cost-effectiveness beyond restricting testing to affected women only.GENETICS in MEDICINE advance online publication, 4 January 2018; doi:10.1038/gim.2017.231.

We identified a large Chinese family with X-linked juvenile retinoschisis. The purpose of this study was to report the clinical findings of the family and to identify the genetic mutation by screening the retinoschisis 1 (RS1) gene. Family history was collected and all family members underwent routine ophthalmic examination. Venous blood was collected from family members and genomic DNA was extracted. The exons of RS1 were screened by PCR followed by direct sequencing and/or restriction enzyme digestion. The pedigree of interest was a four-generation family with 52 family members, including seven affected individuals. The proband was a 5-year-old boy showing highly elevated bullous retinoschisis with moderate vitreous hemorrhage in both eyes. Vitrectomy was performed in the left eye of the proband. Five affected males showed large peripheral retinoschisis in both eyes, either involving the macula or combined with foveal stellate cystic change. One of the affected family members showed only a foveal stellate cystic change in both eyes without periphery retinoschisis. Visual acuity of affected individuals ranged from hand motion to 0.4. The R213W mutation in exon 6 of RS1 was identified in all affected individuals, predicting an amino acid substitution of arginine to tryptophan at codon 213. Our data show that the R213W mutation in RS1 causes various severities of retinoschisis in a large Chinese family, providing further evidence for X-linked juvenile retinoschisis phenotypic variability.

Efficient implementation of the global eradication strategies consisting of Acute Flaccid Paralysis (AFP) surveillance and mass immunization campaigns led to interruption of indigenous wild poliovirus transmission in Cameroon in 1999. This study describes type 1 and type 3 wild poliovirus (WPV) importation, incidence, geographic distribution and control since the original interruption of transmission in Cameroon. Stool samples from AFP patients under the age of 15 years in Cameroon were collected nationwide and subjected to virus isolation on RD and L20B cell cultures. Resulting virus isolates were typed by intratypic differentiation (ITD) and analysis of the VP1 coding sequence of the viral genome. Surveillance data originating from Cameroon between 2000 and 2014 were considered for retrospective descriptive analyses. From 2003 to 2009, multiple WPV importation events from neighboring countries affected mainly in the northern regions of Cameroon but did not led to sustained local transmission. Throughout this period, 16 WPV1 and 5 WPV3 were detected and identified as members of multiple clusters within type-specific West Africa B genotypes (WEAF-B). In 2013-2014, a polio outbreak associated to a highly evolved ("orphan") WPV1 affected four southern regions of Cameroon. The appearance of highly evolved lineage of type 1 WPV suggests potential surveillance gap and underscore the need to maintain comprehensive polio immunization activities and sensitive surveillance systems in place as long as any country in the world remains endemic for WPV.

A cohort of family members with various chronic diseases including Crohn’s disease, asthma, complex regional pain syndrome, hypothyroidism, type 1 diabetes mellitus, and lymphangiomatosis and/or evidence of infection by Mycobacterium avium subsp. paratuberculosis (MAP) are described in this series of case reports. MAP was cultured from the blood of three members affected by the first five diseases and there was accompanying elevated anti-MAP IgG in two members. The patient affected by the sixth disease has a markedly elevated anti-MAP titer. The two patients affected by the first four diseases have been treated with a combination of anti-MAP antibiotics and ultraviolet blood irradiation therapy with resolution of the disease symptomatology and inability to culture MAP in post treatment blood samples. These case reports of patients with MAP infections provide supportive evidence of a pathogenic role of MAP in humans. PMID:25852293

The year 2016 has marked the highest number of displaced people worldwide on record. A large number of these refugees are women, yet little is known about their specific situation and the hurdles they have to face during their journey. Herein, we investigated whether sociodemographic characteristics and traumatic experiences in the home country and during the flight affected the quality of life of refugee women arriving in Germany in 2015-2016. Six hundred sixty-three women from six countries (Afghanistan, Syria, Iran, Iraq, Somalia, and Eritrea) living in shared reception facilities in five distinct German regions were interviewed by native speakers using a structured questionnaire. Sociodemographic data and information about reasons for fleeing, traumatic experiences, symptoms, quality of life, and expectations towards their future were elicited. All information was stored in a central database in Berlin. Descriptive analyses, correlations, and multivariate analyses were performed. The most frequent reasons cited for fleeing were war, terror, and threat to one's life or the life of a family member. Eighty-seven percent of women resorted to smugglers to make the journey to Europe, and this significantly correlated to residence in a war zone (odds ratio (OR) = 2.5, 95% confidence interval (CI) = 1.4-4.6, p = 0.003) and homelessness prior to fleeing (OR = 2.1, 95% CI = 1-4.3, p = 0.04). Overall the described quality of life by the women was moderate (overall mean = 3.23, range of 1-5) and slightly worse than that of European populations (overall mean = 3.68, p < 0.0001). The main reasons correlating with lower quality of life were older age, having had a near-death experience, having been attacked by a family member, and absence of health care in case of illness. Refugee women experience multiple traumatic experiences before and/or during their journey, some of which are gender-specific. These experiences affect the quality of life in their current country of residence and might impact their integration. We encourage the early investigation of these traumatic experiences to rapidly identify women at higher risk and to improve health care for somatic and mental illness.

Schindler disease: the molecular lesion in the alpha-N-acetylgalactosaminidase gene that causes an infantile neuroaxonal dystrophy.

PubMed Central

Wang, A M; Schindler, D; Desnick, R

1990-01-01

Schindler disease is a recently recognized infantile neuroaxonal dystrophy resulting from the deficient activity of the lysosomal hydrolase, alpha-N-acetylgalctosaminidase (alpha-GalNAc). The recent isolation and expression of the full-length cDNA encoding alpha-GalNAc facilitated the identification of the molecular lesions in the affected brothers from family D, the first cases described with this autosomal recessive disease. Southern and Northern hybridization analyses of DNA and RNA from the affected homozygotes revealed a grossly normal alpha-GalNAc gene structure and normal transcript sizes and amounts. Therefore, the alpha-GalNAc transcript from an affected homozygote was reverse-transcribed, amplified by the polymerase chain reaction (PCR), and sequenced. A single G to A transition at nucleotide 973 was detected in multiple subclones containing the PCR products. This point mutation resulted in a glutamic acid to lysine substitution in residue 325 (E325K) of the alpha-GalNAc polypeptide. The base substitution was confirmed by dot blot hybridization analyses of PCR-amplified genomic DNA from family members with allele-specific oligonucleotides. Furthermore, transient expression of an alpha-GalNAc construct containing the E325K mutation resulted in the expression of an immunoreactive polypeptide which had no detectable alpha-GalNAc activity.

2014-12-01

To describe the phenotypic variability in a consanguineous family with genetically confirmed X-linked retinoschisis. Five patients, including one homozygous female, were characterized by clinical examination, optical coherence tomography, fundus autofluorescence, mapping of macular pigment optical density, electroretinography, and DNA testing. The 36-year-old male index patient showed a ring of enhanced autofluorescence and outer retinal atrophy on optical coherence tomography. Electroretinography testing revealed a reduced a/b ratio. His mother presented with a central atrophic retina with markedly reduced autofluorescence signal and a surrounding ring of enhanced autofluorescence. The 40-year-old brother of the index patient and his 2 sons showed characteristic signs for X-linked retinoschisis, including retinal schisis and a reduced a/b ratio. Genetic testing revealed a c.293C>A mutation in the RS1 gene in all affected family members while the mother of the index patient was homozygous for this mutation. X-linked retinoschisis can present with a wide phenotypic variability. Here, detailed family history and genetic testing established the diagnosis of X-linked retinoschisis despite striking differences in phenotypic presentation in affected subjects, homozygosity of one affected female, and seemingly dominant inheritance in three subsequent generations because of multiple consanguinity.

When do next-of-kin opt-in? Anticipated regret, affective attitudes and donating deceased family member's organs.

2014-12-01

This research assessed whether affective factors promote and prevent family members from donating their loved one's organs. Participants (N = 191) imagined that a family member had died and that they had to decide whether or not to donate their organs and body parts for transplantation purposes. The least organs and body parts were donated when the deceased opposed donation. Moreover, participants who were not registered organ donors donated fewer organs than registered donors. This effect was mediated by anticipated regret, disgust and the perceived benefits of donation. Organ donation campaigns should target such factors to increase donor rates. © The Author(s) 2013.

Caregivers of people living with HIV (PLH) in Thailand face tremendous caregiver burden. This study examines complex ways in which caregivers’ mental health affects their levels of caregiver burden. This study uses data from 409 caregivers of PLH in northern and north-eastern Thailand. Multiple regression models were used to examine the predictors of caregiver burden. Depression was significantly associated with caregiver burden (P < 0.0001) and being HIV positive (P = 0.015). Inverse associations were observed between depression and quality of life (P < 0.0001) and caregiver burden and quality of life (P = 0.004). Social support had direct positive association with caregiver’s quality of life (P < 0.0001). Our findings underscore the complex relationship between caregiver burden, depression and HIV-status. Interventions that address the caregiver burden are urgently needed. PMID:20158549

Here, we report the effect of curcumin on cellular and developmental mechanisms in the eukaryotic model, Dictyostelium discoideum. Dictyostelium proliferation was inhibited in the presence of curcumin, which also suppressed the prestarvation marker, discoidin I, members of the yakA-mediated developmental signaling pathway, and expression of the extracellular matrix/cell adhesion proteins (DdCAD and csA). This resulted in delayed chemotaxis, adhesion, and development of the organism. In contrast to the inhibitory effects on developmental genes, curcumin induced gstAmore » gene expression, overall GST activity, and generated production of reactive oxygen species.

Respiratory syncytial virus mechanisms to interfere with type 1 interferons.

PubMed

Barik, Sailen

2013-01-01

Respiratory syncytial virus (RSV) is a member of the Paramyxoviridae family that consists of viruses with nonsegmented negative-strand RNA genome. Infection by these viruses triggers the innate antiviral response of the host, mainly type I interferon (IFN). Essentially all other viruses of this family produce IFN suppressor functions by co-transcriptional RNA editing. In contrast, RSV has evolved two unique nonstructural proteins, NS1 and NS2, to effectively serve this purpose. Together, NS1 and NS2 degrade or sequester multiple signaling proteins that affect both IFN induction and IFN effector functions. While the mechanism of action of NS1 and NS2 is a subject of active research, their effect on adaptive immunity is also being recognized. In this review, we discuss various aspects of NS1 and NS2 function with implications for vaccine design.

Perioperative pain management after total joint replacement continues to be a concern for orthopaedic nurses. In our institution, the results of routine post-hospital stay surveys had shown below average scores in the area of pain management. This began as a quality management issue, became a pain subcommittee issue, and drew in the research nurses to ask what we can learn from this process. Changing the method of handling pain management is not easy, but it makes a difference in patients' hospital experiences. We learned that cooperation and expertise from multiple departments within the institution and some organizations outside the institution is needed to bring about change. We learned that education of not just staff members but also patients on pain management affected the outcome. This article describes our journey to enhance pain management in our institution.

The objective of this study was to better understand the experiences of family members in the nursing home to hospital transfer decision making process. Semi-structured interviews were conducted with 20 family members who had recently been involved in a nursing home to hospital transfer decision. Family members perceived themselves to play an advocacy role in their resident's care and interview themes clustered within three over-arching categories: Family perception of the nursing home's capacity to provide medical care: Resident and family choices; and issues at 'hand-off' and the hospital. Multiple sub-themes were also identified. Findings from this study contribute to knowledge surrounding the nursing home transfer decision by illuminating the experiences of family members in the transfer decision process.

Association of psychosis, affective disorders and diseases affecting the immune system.

Purpose of the article: There are indications of altered immune activity in depressed and psychotic patients compared to healthy controls in several studies. To explore the clinical importance of this phenomenon we examined the relation between different disorders affecting the immune system and psychoses and depression, respectively. A total of 276 patients consecutively admitted to a psychiatric acute ward were included in the study. Of these 41 patients fulfilled the criteria for ICD-10 F20-29 (psychotic) diagnosis and 157 patients a F30-39 (affective) diagnosis. Information on diseases affecting the immune system in patients themselves and family members of the patients were obtained by a self-report questionnaire. Comparing the two groups showed a significant correlation between the F20-29 group and eczema (r = -0.116, p = .037). Comparing what patients reported for family members showed a significantly higher frequency of epilepsy (p = .033) in the F20-29 group. Summarizing all immunological diseases for family members showed a significantly higher frequency in the F30-39 group compared to the F20-29 group (χ 2  = 4, 82, df = 1, p = .028). There may be differences between the F20-29 and F30-39 groups and their family members regarding risk for diseases affecting the immune system. This is in line with different activity of the immune system measured in blood for the disorders and may add information regarding etiology and pathology of these psychiatric diseases. Further studies including a greater number of subjects, as well as confirmation of the immunological diseases through blood samples are needed.

An approximation method for configuration optimization of trusses

Hansen, Scott R.; Vanderplaats, Garret N.

1988-01-01

Two- and three-dimensional elastic trusses are designed for minimum weight by varying the areas of the members and the location of the joints. Constraints on member stresses and Euler buckling are imposed and multiple static loading conditions are considered. The method presented here utilizes an approximate structural analysis based on first order Taylor series expansions of the member forces. A numerical optimizer minimizes the weight of the truss using information from the approximate structural analysis. Comparisons with results from other methods are made. It is shown that the method of forming an approximate structural analysis based on linearized member forces leads to a highly efficient method of truss configuration optimization.

2011-02-01

This paper presents work to identify factors affecting effectiveness of agri-business ventures (A-BVs) on the side of providers as perceived by their members. A survey was conducted among 95 members of A-BVs in Zanjan province, Iran. To collect data, a questionnaire was designed. Two distinct groups of A-BVs with low (group 1) and high (group 2) perceived (evaluated) levels of effectiveness were revealed. The study showed that there were significant differences between the two groups on important characteristics of A-BVs and their members. The study also found that there were statistically significant relationships between A-BVs' governance structure and capacity, management and organization characteristics and the perceived effectiveness, whereas there were no statistically significant relationships between A-BVs' advisory methods characteristic applied by members and the perceived effectiveness. Logistic regression results also showed that level of application of rules encouraging members' active participation in important decision makings, clear terms of reference to guide contracting procedures, roles, and responsibilities of parties involved, type of people served and geographical area of program coverage, and members' ability to use Information and Communication Technologies (ICTs) were predictors of the perceived (evaluated) effectiveness of A-BVs. The study showed that evaluation of members of effectiveness of A-BVs would not be the same. It is suggested that Iranian public agricultural extension organization, as responsible organization for monitoring and evaluating services conducted by A-BVs, considered these differences between members with different levels of some important variables. 2010 Elsevier Ltd.

2016-12-01

In this study the authors explored how people with recently diagnosed multiple sclerosis (MS) experience their disease within their family lives. Ten people in various stages of the cycle of family life (leaving home, finding a partner, raising children, parenting adolescents, launching children) who had been diagnosed with MS were interviewed in half-structured conversational interviews. Transcriptions were analyzed following a phenomenological approach. Five themes were found: (a) dwindling capacity for housekeeping and childcare (b) struggling to ask for or to accept help, (c) countering awkward attitudes toward my illness, (d) suspecting family members of concealing their, and (e) watching family members wrestle with your illness. The participants described that their illness affected their ability to care for their family and home as they used to. Only a couple of studies have addressed the first person perspective of patients on family and MS. The study expands on these studies by exploring not previously examined perspectives on leaving home, finding a partner, parenting adolescents, and launching children. The findings on family and MS, approached as elements of the first person perspective of MS patients, may guide future research. Given the pivotal role of worries on family in patient experience of MS, we argue that acknowledgment of family as a constitutive element of the patient perspective should be integrated in regular MS care. The authors suggest that the clinical handling of MS as a family issue needs to be done thoughtfully and with attention to the specifics of each unique family situation.

Respiratory syncytial virus nonstructural proteins decrease levels of multiple members of the cellular interferon pathways.

PubMed

Swedan, Samer; Musiyenko, Alla; Barik, Sailen

2009-10-01

Viruses of the Paramyxoviridae family, such as the respiratory syncytial virus (RSV), suppress cellular innate immunity represented by type I interferon (IFN) for optimal growth in their hosts. The two unique nonstructural (NS) proteins, NS1 and NS2, of RSV suppress IFN synthesis, as well as IFN function, but their exact targets are still uncharacterized. Here, we investigate if either or both of the NS proteins affect the steady-state levels of key members of the IFN pathway. We found that both NS1 and NS2 decreased the levels of TRAF3, a strategic integrator of multiple IFN-inducing signals, although NS1 was more efficient. Only NS1 reduced IKKepsilon, a key protein kinase that specifically phosphorylates and activates IFN regulatory factor 3. Loss of the TRAF3 and IKKepsilon proteins appeared to involve a nonproteasomal mechanism. Interestingly, NS2 modestly increased IKKepsilon levels. In the IFN response pathway, NS2 decreased the levels of STAT2, the essential transcription factor for IFN-inducible antiviral genes. Preliminary mapping revealed that the C-terminal 10 residues of NS1 were essential for reducing IKKepsilon levels and the C-terminal 10 residues of NS2 were essential for increasing and reducing IKKepsilon and STAT2, respectively. In contrast, deletion of up to 20 residues of the C termini of NS1 and NS2 did not diminish their TRAF3-reducing activity. Coimmunoprecipitation studies revealed that NS1 and NS2 form a heterodimer. Clearly, the NS proteins of RSV, working individually and together, regulate key signaling molecules of both the IFN activation and response pathways.

Representatives of the family Methanosarcinaceae were analyzed phylogenetically by comparing partial sequences of their methyl-coenzyme M reductase (mcrI) genes. A 490-bp fragment from the A subunit of the gene was selected, amplified by the PCR, cloned, and sequenced for each of 25 strains belonging to the Methanosarcinaceae. The sequences obtained were aligned with the corresponding portions of five previously published sequences, and all of the sequences were compared to determine phylogenetic distances by Fitch distance matrix methods. We prepared analogous trees based on 16S rRNA sequences; these trees corresponded closely to the mcrI trees, although the mcrI sequences of pairs of organisms had 3.01 +/- 0.541 times more changes than the respective pairs of 16S rRNA sequences, suggesting that the mcrI fragment evolved about three times more rapidly than the 16S rRNA gene. The qualitative similarity of the mcrI and 16S rRNA trees suggests that transfer of genetic information between dissimilar organisms has not significantly affected these sequences, although we found inconsistencies between some mcrI distances that we measured and and previously published DNA reassociation data. It is unlikely that multiple mcrI isogenes were present in the organisms that we examined, because we found no major discrepancies in multiple determinations of mcrI sequences from the same organism. Our primers for the PCR also match analogous sites in the previously published mcrII sequences, but all of the sequences that we obtained from members of the Methanosarcinaceae were more closely related to mcrI sequences than to mcrII sequences, suggesting that members of the Methanosarcinaceae do not have distinct mcrII genes.

Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by cognitive impairment, language dysfunction, and/or changes in personality. Recently it has been shown that progranulin (GRN) mutations can cause FTD as well as other neurodegenerative phenotypes. DNA from 30 family members, of whom seven were diagnosed with FTD, in the Karolinska family was available for GRN sequencing. Fibroblast cell mRNA from one affected family member and six control individuals was available for relative quantitative real-time polymerase chain reaction to investigate the effect of the mutation. Furthermore, the cDNA of an affected individual was sequenced. Clinical and neuropathologic findings of a previously undescribed family branch are presented. A frameshift mutation in GRN (g.102delC) was detected in all affected family members and absent in four unaffected family members older than 70 years. Real-time polymerase chain reaction data showed an approximately 50% reduction of GRN fibroblast mRNA in an affected individual. The mutated mRNA transcripts were undetectable by cDNA sequencing. Segregation and RNA analyses showed that the g.102delC mutation, previously reported, causes FTD in the Karolinska family. Our findings add further support to the significance of GRN in FTD etiology and the presence of modifying genes, which emphasize the need for further studies into the mechanisms of clinical heterogeneity. However, the results already call for attention to the complexity of predictive genetic testing of GRN mutations.

To Improve Substance Use Disorder Prevention, Treatment and Recovery: Engage the Family.

PubMed

Ventura, Alicia S; Bagley, Sarah M

: Approximately 21 million people in the United States have a substance use disorder (SUD); the number of family members impacted by a loved one's SUD is exponentially greater. Affected family members of individuals with SUDs are at high risk for developing chronic medical and psychiatric health conditions, are high utilizers of the health care system, and have high health care expenditures. Family members play a central role in the lives of many individuals with SUDs; information given to family members can have a significant impact on persons with addiction and therefore the SUD treatment that an individual might receive. Evidence-based interventions targeting affected family members have been shown to: improve health outcomes for all family members, result in better addiction treatment outcomes, and prevent adolescent substance use. Despite mounting evidence, the health care system has been hesitant to engage families in a meaningful way. Health care providers should consider how implicit and explicit assumptions about the role of family members in SUD development, treatment, and recovery may contribute to this underlying reluctance. Antiquated policies and procedures that alienate family members should be modified (e.g., limiting phone access). Family members have a right to receive professional treatment and to be educated about the difference between mutual/peer support and evidence-based treatment options. Despite the potential for family members to move the needle on the country's current addiction crisis they remain an underutilized resource. A paradigm shift will be required to get the current SUD care continuum to adopt a family-centric model.

Park, Julia; Cunningham, David E

2018-04-23

Introduction Practice-Based Small Group Learning (PBSGL) is a learning programme widely adopted by primary healthcare professions (general practitioners, general practice nurses and pharmacists) in Scotland and other countries in the UK. PBSGL groups recruit members and decide on meeting dates and venues. Study aims To determine how groups recruit new members and discern what are the important attributes of the new members. Method A grounded theory approach was used with purposive sampling to recruit PBSGL groups to the study. Focus groups drawn from established PBSGL groups were conducted by two researchers following an iterative process, with interviews audio-recorded and transcribed, and codes and themes constructed. Data saturation was achieved. Results and conclusions Four themes were identified that affected group recruitment: group formation and purpose; group culture and ethos; experience and seniority range of group members; professional socialisation and cross-fertilisation. Groups whose main purpose was learning encouraged diverse membership, while groups that were stricter with recruitment often prioritised friendship, group safety, trust and peer support over learning. The variation in group's openness to recruitment may make it difficult for potential members to find a group and this may affect the development and expansion of the PBSGL programme.

Kwon, Ji-Wook; Kim, Jin Hyo; Seo, Jiwon

2015-01-01

This paper proposes a Multiple Leader Candidate (MLC) structure and a Competitive Position Allocation (CPA) algorithm which can be applicable for various applications including environmental sensing. Unlike previous formation structures such as virtual-leader and actual-leader structures with position allocation including a rigid allocation and an optimization based allocation, the formation employing the proposed MLC structure and CPA algorithm is robust against the fault (or disappearance) of the member robots and reduces the entire cost. In the MLC structure, a leader of the entire system is chosen among leader candidate robots. The CPA algorithm is the decentralized position allocation algorithm that assigns the robots to the vertex of the formation via the competition of the adjacent robots. The numerical simulations and experimental results are included to show the feasibility and the performance of the multiple robot system employing the proposed MLC structure and the CPA algorithm.

To describe a family with primary familial brain calcification (PFBC) due to SLC20A2 variant showing possible genetic anticipation. We conducted historical, genealogical, clinical, and radiologic studies of a family with PFBC. Clinical evaluations including neurological examination and head computed tomography (CT) scans of a proband and her father were performed. They provided additional information regarding other family members. To identify a causative gene variant, we performed whole-exome sequencing for the proband followed by segregation analysis in other affected members using direct sequencing. In this family, nine affected members were identified over four generations. The proband suffered from chronic daily headache including thunderclap headache. We identified an SLC20A2 (c.509delT, p.(Leu170*)) variant in three affected members over three generations. Interestingly, the age of onset became younger as the disease passed through successive generations, suggestive of genetic anticipation. For clinical purpose, it is important to consider thunderclap headache and genetic anticipation in PFBC caused by SLC20A2 variants. Further investigation is required to validate our observation.

Fabry disease (FD) is an X-linked inherited lysosomal storage disorder caused by mutations in the GLA gene, encoding for the enzyme α-galactosidase A. Although hundreds of mutations in the GLA gene have been described, many of them are variants of unknown significance. Here we report a novel GLA mutation, p.Ile239Met, identified in a large Hungarian three-generation family with FD. A 69 year-old female index patient with a clinical history of renal failure, hypertrophic cardiomyopathy, and 2nd degree AV block was screened for mutation in the GLA gene. Genetic screening identified a previously unreported heterozygous mutation in exon 5 of the GLA gene (c.717A>G; p.Ile239Met). Family screening indicated that altogether 6 family members carried the mutation (5 females, 1 male, average age: 55 ± 16 years). Three family members, including the index patient, manifested the cardiac phenotype of hypertrophic cardiomyopathy, while two other family members were diagnosed with left ventricular hypertrophy. Taking affection status as the presence of hypertrophic cardiomyopathy, left ventricular hypertrophy or elevated lyso-Gb3 levels, all affected family members carried the mutation. Linkage analysis of the family gave a two-point LOD score of 2.01 between the affection status and the p.Ile239Met GLA mutation. Lyso-Gb3 levels were elevated in all carrier family members (range: 2.4-13.8 ng/mL; upper limit of normal +2STD: ≤ 1.8 ng/mL). The GLA enzyme level was markedly reduced in the affected male family member (< 0.2 µmol/L/hour; upper limit of normal ± 2STD: ≥ 2.6 µmol/L/hour). We conclude that the p. Ile239Met GLA mutation is a pathogenic mutation for FD associated with predominant cardiac phenotype.

Effective Collaboration for Scaling Up Health Technologies: A Case Study of the Chlorhexidine for Umbilical Cord Care Experience

2018-01-01

The global health field is replete with examples of cross-organizational collaborative partnerships, such as networks, alliances, coalitions, task forces, and working groups, often established to tackle a shared global health concern, condition, or threat affecting low-income countries or communities. The purpose of this article is to review factors influencing the effectiveness of a multi-agency global health collaborative effort using the Chlorhexidine Working Group (CWG) as our case study. The CWG was established to accelerate the introduction and global scale-up of chlorhexidine for umbilical cord care to reduce infection-related neonatal morbidity and mortality in low-income countries. Questions included: how current and past CWG members characterized the effectiveness, productivity, collaboration, and leadership of the CWG; what factors facilitated or hindered group function; institutional or individual reasons for participating and length of participation in the CWG; and lessons that might be relevant for future global collaborative partnerships. Data were collected through in-depth, semistructured individual interviews with 19 group members and a review of key guiding documents. Six domains of internal coalition functioning (leadership, interpersonal relationships, task focus, participant benefits and costs, sustainability planning, and community support) were used to frame and describe the functioning of the CWG. Collaboration effectiveness was found to depend on: (1) leadership that maintained a careful balance between discipline and flexibility, (2) a strong secretariat structure that supported the evolution of trust and transparent communication in interpersonal relationships, (3) shared goals that allowed for task focus, (4) diverse membership and active involvement from country-level participants, which created a positive benefit-cost ratio for participants, (5) sufficient resources to support the partnership and build sustainable capacity for members to accelerate the transfer of knowledge, and (6) support from the global health community across multiple organizations. Successful introduction and scale-up of new health interventions require effective collaboration across multiple organizations and disciplines, at both global and country levels. The participatory collaborative partnership approach utilized by the Chlorhexidine Working Group offers an instructive learning case. PMID:29602871

Why do certain group members end up liking each other more than others? How does affective reciprocity arise in human groups? The prediction of interpersonal sentiment has been a long-standing pursuit in the social sciences. We combined fMRI and longitudinal social network data to test whether newly acquainted group members' reward-related neural responses to images of one another's faces predict their future interpersonal sentiment, even many months later. Specifically, we analyze associations between relationship-specific valuation activity and relationship-specific future liking. We found that one's own future (T2) liking of a particular group member is predicted jointly by actor's initial (T1) neural valuation of partner and by that partner's initial (T1) neural valuation of actor. These actor and partner effects exhibited equivalent predictive strength and were robust when statistically controlling for each other, both individuals' initial liking, and other potential drivers of liking. Behavioral findings indicated that liking was initially unreciprocated at T1 yet became strongly reciprocated by T2. The emergence of affective reciprocity was partly explained by the reciprocal pathways linking dyad members' T1 neural data both to their own and to each other's T2 liking outcomes. These findings elucidate interpersonal brain mechanisms that define how we ultimately end up liking particular interaction partners, how group members' initially idiosyncratic sentiments become reciprocated, and more broadly, how dyads evolve. This study advances a flexible framework for researching the neural foundations of interpersonal sentiments and social relations that-conceptually, methodologically, and statistically-emphasizes group members' neural interdependence.

To correlate clinical examination with underlying genotype in asymptomatic females who are potential carriers of X-linked developmental cataract (Nance-Horan syndrome). An ophthalmologist blind to the pedigree performed comprehensive ophthalmic examination for 16 available family members (two affected and six asymptomatic females, five affected and three asymptomatic males). Facial features were also noted. Venous blood was collected for sequencing of the gene NHS. All seven affected family members had congenital or infantile cataract and facial dysmorphism (long face, bulbous nose, abnormal dentition). The six asymptomatic females ranged in age from 4-35 years old. Four had posterior Y-suture centered lens opacities; these four also exhibited the facial dysmorphism of the seven affected family members. The fifth asymptomatic girl had scattered fine punctate lens opacities (not centered on the Y-suture) while the sixth had clear lenses, and neither exhibited the facial dysmorphism. A novel NHS mutation (p.Lys744AsnfsX15 [c.2232delG]) was found in the seven patients with congenital or infantile cataract. This mutation was also present in the four asymptomatic girls with Y-centered lens opacities but not in the other two asymptomatic girls or in the three asymptomatic males (who had clear lenses). Lens opacities centered around the posterior Y-suture in the context of certain facial features were sensitive and specific clinical signs of carrier status for NHS mutation in asymptomatic females. Lens opacities that did not have this characteristic morphology in a suspected female carrier were not a carrier sign, even in the context of her affected family members.

Purpose We identified a large Chinese family with X-linked juvenile retinoschisis. The purpose of this study was to report the clinical findings of the family and to identify the genetic mutation by screening the retinoschisis 1 (RS1) gene. Methods Family history was collected and all family members underwent routine ophthalmic examination. Venous blood was collected from family members and genomic DNA was extracted. The exons of RS1 were screened by PCR followed by direct sequencing and/or restriction enzyme digestion. Results The pedigree of interest was a four-generation family with 52 family members, including seven affected individuals. The proband was a 5-year-old boy showing highly elevated bullous retinoschisis with moderate vitreous hemorrhage in both eyes. Vitrectomy was performed in the left eye of the proband. Five affected males showed large peripheral retinoschisis in both eyes, either involving the macula or combined with foveal stellate cystic change. One of the affected family members showed only a foveal stellate cystic change in both eyes without periphery retinoschisis. Visual acuity of affected individuals ranged from hand motion to 0.4. The R213W mutation in exon 6 of RS1 was identified in all affected individuals, predicting an amino acid substitution of arginine to tryptophan at codon 213. Conclusions Our data show that the R213W mutation in RS1 causes various severities of retinoschisis in a large Chinese family, providing further evidence for X-linked juvenile retinoschisis phenotypic variability.

Recent clinical whole exome sequencing (WES) cohorts have identified unanticipated multiple genetic diagnoses in single patients. However, the frequency of multiple genetic diagnoses in families is largely unknown. We set out to identify the rate of multiple genetic diagnoses in probands and their families referred for analysis in two national research programs in Canada. We retrospectively analyzed WES results for 802 undiagnosed probands referred over the past 5 years in either the FORGE or Care4Rare Canada WES initiatives. Of the 802 probands, 226 (28.2%) were diagnosed based on mutations in known disease genes. Eight (3.5%) had two or more genetic diagnoses explaining their clinical phenotype, a rate in keeping with the large published studies (average 4.3%; 1.4 - 7.2%). Seven of the 8 probands had family members with one or more of the molecularly diagnosed diseases. Consanguinity and multisystem disease appeared to increase the likelihood of multiple genetic diagnoses in a family. Our findings highlight the importance of comprehensive clinical phenotyping of family members to ultimately provide accurate genetic counseling. © 2017 John Wiley & Sons A/S.

Multiple sclerosis is a demyelinating disease that causes severe disability in younger patients. Many epidemiology studies have confirmed a variable prevalence. The objective of this study was to analyse the prevalence of this disease in La Rioja (Spain), using such variables as age and sex; type of progression, initial form of the disease, EDSS and number of relapses; disease-modifying treatment and reasons for treatment withdrawal; personal and family history of cancer; and incidence and mortality. Analysis of patients in La Rioja diagnosed with MS (according to Poser criteria or the 2005 McDonald criteria) during a 10-year period (2001-2011). Data were collected from hospital records, multiple sclerosis associations, and personal records kept by neurologists. The MS prevalence rate in La Rioja is 65 patients/100 000 inhabitants with an incidence rate of 3.5 cases/100 000 residents per year. Relapsing-remitting MS is present in 67.6% of the patient total. Mean age of onset is 20-29 years (range, 12 to 70). Most EDSS scores were mostly ≤ 2. Untreated MS cases account for 47.6% of the total and the most commonly used therapy is interferon. We detected 4 haematological tumours and 7 families with multiple members affected by MS. Prevalence and incidence are similar to those found in other regions Spain. The average age at onset age for primary progressive MS is slightly higher than in other papers (40-49 years). In families with multiple patients, MS may be more aggressive. Disability in these patients remains very severe. We require more epidemiology studies with a variety of data gathering methods to support findings for prevalence obtained in different provinces.

In October 2009, the grave of an unknown World War I (WWI) U.S. service member was exhumed in Rembercourt-Sur-Mad Village, in the Lorraine Region of France. The skeletal remains and material evidence were accessioned into the Joint POW/MIA Accounting Command's (JPAC) Central Identification Laboratory (CIL). The personnel records for the associated casualty were requested, received, and reviewed. A dental profile was present among the service member's personal information. There were multiple points of concordance between the dental records of the associated casualty, and the recovered dental remains to include eight restored teeth, 15 unrestored teeth, and three antemortem missing teeth. Distinctive restorations which compared favorably included a porcelain crown and multiple gold foil fillings. All lines of evidence (historical, material evidence/personal effects, anthropological, and dental) and the circumstances of loss compared positively with the associated casualty. On April 1, 2010, the previously unaccounted-for U.S. service member was positively identified and on June 23, 2010, was buried with full military honors at Arlington National Cemetery.

miR-17-92 is a microRNA cluster with six distinct members. Here, we show that the miR-17-92 cluster and its individual members modulate chronic neuropathic pain. All cluster members are persistently upregulated in primary sensory neurons after nerve injury. Overexpression of miR-18a, miR-19a, miR-19b and miR-92a cluster members elicits mechanical allodynia in rats, while their blockade alleviates mechanical allodynia in a rat model of neuropathic pain. Plausible targets for the miR-17-92 cluster include genes encoding numerous voltage-gated potassium channels and their modulatory subunits. Single-cell analysis reveals extensive co-expression of miR-17-92 cluster and its predicted targets in primary sensory neurons. miR-17-92 downregulates the expression of potassium channels, and reduced outward potassium currents, in particular A-type currents. Combined application of potassium channel modulators synergistically alleviates mechanical allodynia induced by nerve injury or miR-17-92 overexpression. miR-17-92 cluster appears to cooperatively regulate the function of multiple voltage-gated potassium channel subunits, perpetuating mechanical allodynia.

Investigation of disorders of sex development (DSD) has resulted in the discovery of multiple sex-determining genes. MAP3K1 encodes a signal transduction regulator in the sex determination pathway and is emerging as one of the more common genes responsible for 46,XY DSD presenting as complete or partial gonadal dysgenesis. Clinical assessment, endocrine evaluation, and genetic analysis were performed in six individuals from four unrelated families with 46,XY DSD. All six individuals were found to have likely pathogenic MAP3K1 variants. Three of these individuals presented with complete gonadal dysgenesis, characterized by bilateral streak gonads with typical internal and external female genitalia, while the other three presented with partial gonadal dysgenesis, characterized by incomplete testicular development, resulting in clitoral hypertrophy with otherwise typical female external genitalia. Testing for MAP3K1 variants should be considered in patients with 46,XY complete or partial gonadal dysgenesis, particularly in families with multiple members affected with 46,XY DSD. Identification of a MAP3K1 variant should prompt an evaluation for DSD in female siblings of the proband. © 2017 Wiley Periodicals, Inc.

Subjects' interaction is the core of most human activities. This is the reason why a lack of coordination is often the cause of missing goals, more than individual failure. While there are different subjective and objective measures to assess the level of mental effort required by subjects while facing a situation that is getting harder, that is, mental workload, to define an objective measure based on how and if team members are interacting is not so straightforward. In this study, behavioral, subjective and synchronized electroencephalographic data were collected from couples involved in a cooperative task to describe the relationship between task difficulty and team coordination, in the sense of interaction aimed at cooperatively performing the assignment. Multiple-brain connectivity analysis provided information about the whole interacting system. The results showed that averaged local properties of a brain network were affected by task difficulty. In particular, strength changed significantly with task difficulty and clustering coefficients strongly correlated with the workload itself. In particular, a higher workload corresponded to lower clustering values over the central and parietal brain areas. Such results has been interpreted as less efficient organization of the network when the subjects' activities, due to high workload tendencies, were less coordinated.

Familial adenomatous polyposis (FAP) is a syndrome characteristically having numerous (hundreds to thousands) polyps in the epithelium of the large intestines with an autosomal dominant inheritance caused by germ line mutations in adenomatous polyposis coli (APC) gene in chromosome 5q21. Most FAP patients have a family history of colorectal polyps and cancer but 25-30% of them are "de novo", without any clinical or genetic evidence of FAP in family members. Prophylactic proctocolectomy is required in almost all patients since all affected patients inevitably develop cancer. We report a case of a 32-year-old man who presented with vague abdominal complaints without any family history, which on evaluation as found to have multiple colorectal polyps and underwent a prophylactic proctocolectomy with end continent ileostomy. Two of his children were evaluated and found to have multiple colorectal polyps on colonoscopy and have been advised regular follow up annually. In conclusion, patients with FAP may present with vague abdominal complaints and without any family history, hence need to be carefully evaluated. Good patient compliance is of prime importance in deciding the treatment and surveillance modality subsequently determining the prognosis of patients with FAP.

Fibroblast growth factors, old kids on the new block

The fibroblast growth factors (FGFs) are a family of cell intrinsic regulatory peptides that control a broad spectrum of cellular activities. The family includes canonic FGFs that elicit their activities by activating the FGF receptor (FGFR) tyrosine kinase and non-canonic members that elicit their activities intracellularly and via FGFR-independent mechanisms. The FGF signaling axis is highly complex due to the existence of multiple isoforms of both ligands and receptors, as well as cofactors that include the chemically heterogeneous heparan sulfate (HS) cofactors, and in the case of endocrine FGFs, the Klotho coreceptors. Resident FGF signaling controls embryonic development, maintains tissue homeostasis, promotes wound healing and tissue regeneration, and regulates functions of multiple organs. However, ectopic or aberrant FGF signaling is a culprit for various diseases, including congenital birth defects, metabolic disorder, and cancer. The molecular mechanisms by which the specificity of FGF signaling is achieved remain incompletely understood. Since its application as a druggable target has been gradually recognized by pharmaceutical companies and translational researchers, understanding the determinants of FGF signaling specificity has become even more important in order to get into the position to selectively suppress a particular pathway without affecting others to minimize side effects.

To report the clinical and genetic findings of Vietnamese families affected with macular corneal dystrophy (MCD) in 2 generations. Two families, including 7 patients and 3 unaffected members, were examined clinically. Blood samples were collected. Fifty normal Vietnamese individuals were used as controls. Genomic DNA was extracted from leukocytes. Analysis of the carbohydrate sulfotransferase (CHST6) gene was performed using polymerase chain reaction and direct sequencing. The typical form of MCD was recognized in family B, in which sequencing of CHST6 gene revealed an nt 1067-1068ins(GGCCGTG) mutation (frameshift after 125V) homozygously in MCD patients and heterozygously in the unaffected members. Family N also showed clinical features of MCD, moderate in the mother but severe in the affected son. Sequencing revealed a single heterozygous Arg211Gln in the mother, compound heterozygous Arg211Gln+ Gln82Stop in the affected son, and heterozygous Arg211Gln mutation in the unaffected members. The identified mutations in these pedigrees were excluded from normal controls. The novel frameshift and compound heterozygous mutations might be responsible for MCD in the families studied. The phenotypic variation between affected parents and offspring was unclear. In family N, severe MCD phenotype seen in the affected son may be due the fact that he had an early stop codon mutation (Gln82Stop).

Background Survey data indicate that individuals with disabilities in the United States often experience less advantageous economic and social resources than individuals without disabilities. Furthermore, they often reside with other individuals with disabilities in the same household. However, less is known about resource availability when multiple child and adult household members have a disability. Objective We use child-level data from the 2000 Census to examine the relationship between aggregation of disability in households with children and education, labor force participation, poverty level, and inadequate housing. Methods We utilize tabular analysis and Kruskal–Wallis tests to examine how resources in education, employment, income, and housing adequacy compare for children with disabilities who are the only member of their household with a disability, children with disabilities who live in a household with at least one other member with a disability, children without disabilities who live in a household where no other member has a disability, and children without disabilities who live in a household where at least one other member has a disability. Results Among children without a disability, 86% live in a household in which no other member has a disability. Among children with a disability, 53% live in a household in which no other adult or child has a disability. Poverty, inadequate housing, and low adult education were more two times more likely – and adult unemployment over five times more likely – in households with multiple members with disability versus households without disability. Conclusion There is a high prevalence of aggregation of adults and children with disability in households of children with disability. These households have substantially fewer resources than households who do not have disabilities. PMID:23021734

Medical requirements are currently being developed for NASA's space exploration program. Lunar surface operations for crews returning to the moon will be performed on a daily basis to conduct scientific research and construct a lunar habitat. Inherent to aggressive surface activities is the potential risk of injury to crew members. To develop an evidence-base for handling medical contingencies on the lunar surface, a simulation project was conducted using the moon-Mars analog environment at Devon Island, Nunavut, high Canadian Arctic. A review of the Apollo lunar surface activities and personal communications with Apollo lunar crew members provided a knowledge base of plausible scenarios that could potentially injure an astronaut during a lunar extravehicular activity. Objectives were established to 1) demonstrate stabilization, field extraction and transfer an injured crew member to the habitat and 2) evaluate audio, visual and biomedical communication capabilities with ground controllers at multiple mission control centers. The simulation project s objectives were achieved. Among these objectives were 1) extracting a crew member from a sloped terrain by a two-member team in a 1-g analog environment, 2) establishing real-time communication to multiple space centers, 3) providing biomedical data to flight controllers and crew members, and 4) establishing a medical diagnosis and treatment plan from a remote site. The simulation project provided evidence for the types of equipment and methods needed for planetary space exploration. During the project, the crew members were confronted with a number of unexpected scenarios including environmental, communications, EVA suit, and navigation challenges. These trials provided insight into the challenges of carrying out a medical contingency in an austere environment. The knowledge gained from completing the objectives of this project will be incorporated into the exploration medical requirements involving an incapacited astronaut on the lunar surface.

The aim of this study was to explore if there were some specific factors pertinent to health-related quality of life (HRQoL) that could affect self-experienced suicide ideation in men with prostate cancer (PCa). Questionnaires containing 45 items were distributed to members of the Swedish Prostate Cancer Federation in May 2012. Out of 6,400 distributed questionnaires, 3,165 members (50 %) with PCa completed the questionnaires. Those members expressed their experienced HRQoL and experienced suicide ideation using VAS-like scales as well as multiple-choice questions. Both descriptive and analytical statistical methods were employed. A regression model was used to explore the relationship between experienced health-related quality of life and experienced suicide ideation. Generally, the respondents rated their self-experienced health-related quality of life as good. About 40 % of the participants had experienced problem with incontinence, and 23 % had obstructions during miction. About 7 % of the respondents experienced suicidal ideation, at least sometime. The regression model showed statistically significant relationships between suicide ideation, on the one hand, and lower self-rated health-related quality of life (P < 0.001), physical pain (P = 0.04), pain during miction (P = 0.03), and low-rated mental / physical energy (P = 0.03), on the other. It is quite necessary to know which specific disease and treatment-related problems can trigger suicide ideations in men with prostate cancer and to try to direct treatment, care, and psychosocial resources to alleviate these problems in time.

Examining family meetings at end of life: The model of practice in a hospice inpatient unit.

Our purpose was to rigorously examine the nature of family meetings as conducted in an inpatient hospice care unit in order to generate an inductive theoretical model. In this two-phase project, we first interviewed eight members of the interdisciplinary care team who participated in multiple family meetings each week. Interview questions explored why and how they conducted family meetings. Using an observation template created from these interview data, we subsequently conducted ethnographic observations during family meetings. Using the methods of grounded theory, our findings were synthesized into a theoretical model depicting the structure and process of formal family meetings within this setting. The core of the family meeting was characterized by cognitive and affective elements aimed at supporting the family and facilitating quality care by clarifying the past, easing the present, and protecting the future. This inductive model was subsequently found to be highly aligned with a sense of coherence, an important influence on coping, and adaptation to the stress of a life-limiting illness. Provider communication with family members is particularly critical during advanced illness and end-of-life care. The National Consensus Project clinical practice guidelines for quality palliative care list regular family meetings among the recommended practices for excellent communication during end-of-life care, but do not provide specific guidance on how and when to provide such meetings. Our findings provide a theoretical model that can inform the design of a family meeting to address family members' needs for meaningful and contextualized information, validation of their important contributions to care, and preparation for the patient's death.

Purpose To describe the phenotype of a novel Wolframin (WFS1) mutation in a family with autosomal dominant optic neuropathy and deafness. The study is designed as a retrospective observational case series. Methods Seven members of a Dutch family underwent ophthalmological, otological, and genetical examinations in one institution. Fasting serum glucose was assessed in the affected family members. Results All affected individuals showed loss of neuroretinal rim of the optic nerve at fundoscopy with enlarged blind spots at perimetry. They showed a red-green color vision defect at color vision tests and deviations at visually evoked response tests. The audiograms of the affected individuals showed hearing loss and were relatively flat. The unaffected individuals showed no visual deviations or hearing impairment. The affected family members had no glucose intolerance. Leber hereditary optic neuropathy (LHON) mitochondrial mutations and mutations in the Optic atrophy-1 gene (OPA1) were excluded. In the affected individuals, a novel missense mutation c.2508G>C (p.Lys836Asn) in exon 8 of WFS1 was identified. Conclusions This study describes the phenotype of a family with autosomal dominant optic neuropathy and hearing impairment associated with a novel missense mutation in WFS1. PMID:20069065

Wolfram syndrome (WFS) is a neurodegenerative genetic condition characterized by juvenile-onset of diabetes mellitus and optic atrophy. We studied clinical features and the molecular basis of severe WFS (neurodegenerative complications) in two consanguineous families from Iran. A clinical and molecular genetic investigation was performed in the affected and healthy members of two families. The clinical diagnosis of WFS was confirmed by the existence of diabetes mellitus and optic atrophy in the affected patients, who in addition had severe neurodegenerative complications. Sequencing of WFS1 was undertaken in one affected member from each family. Targeted mutations were tested in all members of relevant families. Patients had most of the reported features of WFS. Two affected males in the first family had fathered unaffected children. We identified two homozygous mutations previously reported with apparently milder phenotypes: family 1: c.631G>A (p.Asp211Asn) in exon 5, and family 2: c.1456C>T (p.Gln486*) in exon 8. Heterozygous carriers were unaffected. This is the first report of male Wolfram patients who have successfully fathered children. Surprisingly, they also had almost all the complications associated with WFS. Our report has implications for genetic counseling and family planning advice for other affected families. PMID:22781099

On the placement of active members in adaptive truss structures for vibration control

NASA Technical Reports Server (NTRS)

Lu, L.-Y.; Utku, S.; Wada, B. K.

1992-01-01

The problem of optimal placement of active members which are used for vibration control in adaptive truss structures is investigated. The control scheme is based on the method of eigenvalue assignment as a means of shaping the transient response of the controlled adaptive structures, and the minimization of required control action is considered as the optimization criterion. To this end, a performance index which measures the control strokes of active members is formulated in an efficient way. In order to reduce the computation burden, particularly for the case where the locations of active members have to be selected from a large set of available sites, several heuristic searching schemes are proposed for obtaining the near-optimal locations. The proposed schemes significantly reduce the computational complexity of placing multiple active members to the order of that when a single active member is placed.

In this paper, we discussed the structural behavior of bolted lap-joint connections in pultruded FRP structural members. Especially, bolted connections in pultruded FRP members are investigated for their failure modes and strength. Specimens with single and multiple bolt-holes are tested in tension under bolt-loading conditions. All of the specimens are instrumented with strain gages and the load-strain responses are monitored. The failed specimens are examined for the cracks and failure patterns. The purpose of this paper is to predict the failure strength by using the ratio of the results obtained by the experiment and the finite element analysis. In the study, several tests are conducted to determine the mechanical properties of pultruded FRP materials before the main experiment. The results are used in the finite element analysis for single and multiple bolted lap-joint specimens. The results obtained by the experiment are compared with the results obtained by the finite element analysis.

The American Society for Colposcopy and Cervical Pathology Colposcopy Standards Committee organized multiple working groups to draft colposcopy standards for the United States. As part of this project, international quality assurance and improvement measures were examined. The quality improvement working group performed a systematic review of the literature to collate international guidelines related to quality improvement. Source guidelines were collected using searches in Medline, Google Scholar, the International Federation of Cervical Pathology and Colposcopy Web site, other regional colposcopy group's Web sites, and communications with International Federation of Cervical Pathology and Colposcopy board of directors' members and other expert members of various national groups. Once identified, the sources were reviewed by multiple workgroup members for potential guideline materials. Fifty-six unique documents were identified, of which 18 met inclusion criteria and contributed data to the analysis. Information was abstracted and grouped by related subject. Wide variation exists in colposcopy guidance and quality indicators from regional and national colposcopy societies. Abstracted international guidelines are presented.

To investigate how family members' attitudes toward functional regain, and patients' knowledge and intention of independence influence poststroke rehabilitation. Cross-sectional study. Three rehabilitation inpatient settings. Younger (n=79) and older (n=84) poststroke patients, along with their family members (spouses, n=104; children, n=59). Not applicable. Custom-designed questionnaires were used to tap into the patients' knowledge about rehabilitation (Patient's Rehabilitation Questionnaire-Knowledge About Rehabilitation) and intention of independence (Patient's Rehabilitation Questionnaire-Intention of Independence), and family members' attitudes toward patients in performing basic activities of daily living (BADL) (Family Member Attitudes Questionnaire-BADL) and instrumental activities of daily living (Family Member Attitudes Questionnaire-instrumental activities of daily living). The rehabilitation outcomes included gains in motor, cognitive, and emotional functions, and self-care independence, measured with common clinical instruments. The Family Member Attitudes Questionnaire-BADL predicted cognitive outcome and the Patient's Rehabilitation Questionnaire-Intention of Independence predicted motor outcome for both groups. Differential age-related effects were revealed for the Patient's Rehabilitation Questionnaire-Intention of Independence in predicting emotional outcome only for the younger group, and self-care independence only for the older group. Patients' intention of independence positively affected motor recovery, while family members' positive attitudes promoted cognitive regain. The findings suggested plausible age-related differences in how patients' intentions affect emotion versus self-care independence outcomes. Future studies should explore strategies for promoting positive attitudes toward independence among patients and family members during poststroke rehabilitation.

Degraded perceptual and affective processing of racial out-groups: An electrophysiological approach.

PubMed

2017-08-01

Human beings process perceptual and affective information of racial out-groups in a degraded manner. Relative to racial in-group members, we lack perceptual individuation of racial out-group members and empathize their pain to a less degree. To date, however, the relationship between the deficiency of individuation and the impairment of empathy in responding to racial out-groups remains elusive. By recording event-related brain potentials in response to racial in-group and out-group faces portraying pain and neutral expressions, we simultaneously measured neural activity that underpinned individuation and empathy. Deficiency in individuating members of racial out-groups, manifesting as reduced reactivity of face-sensitive N170 in the occipitotemporal region of the brain, predicted attenuation of fronto-central empathic response to the suffering of racial out-groups. Further, the individuation bias mediated the influence of racial prejudice on racial in-group bias in empathic neural responses. These findings suggest an interplay between degraded perceptual and affective processing of racial out-groups.

Women and AIDS caregiving: women's work?

In this ethnographic study, I examine personal, kinship, and social obligations and the role of women in the traditional Thai family. Under what circumstances do women take on the responsibility to care or not care, and how do they cope with the disease and care when they are also infected? Fifteen women who were afflicted or affected by HIV/AIDS participated in in-depth interviews and participant observations. Analysis employed mainly qualitative methods following Spradley. I show that women who are responsible for caring for both themselves and others, including members of their immediate families or extended family members, face a double jeopardy by virtue of their inferior role and status. When HIV-infected women experience illness, sometimes they feel split; they are incapable of functioning normally, yet they are obligated to do "What they've got to do." Women as carers feel that they have to care because they want to free someone else from suffering despite the fact that they are also suffering. Women roles as family carers seem to be both psychologically and socially constructed. AIDS care is not just a labour of love, but also is done in the spirit of work following Buddhist beliefs of karma and metta. In conclusion, traditional, persistent gender imbalances and inequalities influence women's sexuality, vulnerability, responsibility, and caregiving. When women become infected with HIV and sick with AIDS, their quality of life drops because of the physical, psychological, cultural value, and economic burdens of care they face. AIDS then necessitates rather than prevents women from fulfilling their multiple roles. Consequently, there is a need for greater support especially among Thai women who are afflicted and affected with AIDS.

Patients with maturity-onset diabetes of the young (MODY) might be over-represented in families with histories of Type 1 diabetes. Our aim was to re-evaluate families participating in the Czech T1D Prediction Programme (PREDIA.CZ) with at least two members affected with diabetes to assess the proportion of MODY among these families and determine its most significant clinical predictors. Of the 557 families followed up by the PREDIA.CZ, 53 (9.5%) had two or more family members with diabetes. One proband with diabetes from these families was chosen for direct sequencing of the GCK, HNF1A, HNF4A and INS genes. Non-parametric tests and a linear logistic regression model were used to evaluate differences between MODY and non-MODY families. MODY was genetically diagnosed in 24 of the 53 families with multiple occurrences of diabetes (45%). Mutations were detected most frequently in GCK (58%), followed by HNF1A (38%) and INS (4%). MODY families were more likely to have a parent with diabetes and had a higher proportion of females with diabetes than non-MODY families. Higher age (P < 0.001), a lower level of HbA 1c (P < 0.001) at clinical onset and at least two generations affected by diabetes were the variables most predictive for probands of MODY families already presenting with diabetes. A prediction programme for Type 1 diabetes would provide a useful new source of patients with MODY most likely to benefit from an accurate diagnosis. This identification has implications for patient treatment and disease prognosis. © 2015 Diabetes UK.

Adverse childhood experiences are significant risk factors for physical and mental illnesses in adulthood. Traumatic brain injury/concussion is a challenging condition where pre-injury factors may affect recovery. The association between childhood adversity and traumatic brain injury/concussion has not been previously reviewed. The research question addressed is: What is known from the existing literature about the association between adverse childhood experiences and traumatic brain injury/concussion in adults? All original studies of any type published in English since 2007 on adverse childhood experiences and traumatic brain injury/concussion outcomes were included. The literature search was conducted in multiple electronic databases. Arksey and O'Malley and Levac et al.'s scoping review frameworks were used. Two reviewers independently completed screening and data abstraction. The review yielded six observational studies. Included studies were limited to incarcerated or homeless samples, and individuals at high-risk of or with mental illnesses. Across studies, methods for childhood adversity and traumatic brain injury/concussion assessment were heterogeneous. A positive association between adverse childhood experiences and traumatic brain injury occurrence was identified. The review highlights the importance of screening and treatment of adverse childhood experiences. Future research should extend to the general population and implications on injury recovery. Implications for rehabilitation Exposure to adverse childhood experiences is associated with increased risk of traumatic brain injury. Specific types of adverse childhood experiences associated with risk of traumatic brain injury include childhood physical abuse, psychological abuse, household member incarceration, and household member drug abuse. Clinicians and researchers should inquire about adverse childhood experiences in all people with traumatic brain injury as pre-injury health conditions can affect recovery.

Aim Genetic and clinical complexities are common features of most psychiatric illnesses that pose a major obstacle in risk-gene identification. Attention deficit hyperactivity disorder (ADHD) is the most prevalent child-onset psychiatric illness, with high heritability. Over the past decade, numerous genetic studies utilizing various approaches, such as genome-wide association, candidate-gene association, and linkage analysis, have identified a multitude of candidate loci/genes. However, such studies have yielded diverse findings that are rarely reproduced, indicating that other genetic determinants have not been discovered yet. In this study, we carried out sib-pair analysis on seven multiplex families with ADHD from Saudi Arabia. We aimed to identify the candidate chromosomal regions and genes linked to the disease. Patients and methods A total of 41 individuals from multiplex families were analyzed for shared regions of homozygosity. Genes within these regions were prioritized according to their potential relevance to ADHD. Results We identified multiple genomic regions spanning different chromosomes to be shared among affected members of each family; these included chromosomes 3, 5, 6, 7, 8, 9, 10, 13, 17, and 18. We also found specific regions on chromosomes 8 and 17 to be shared between affected individuals from more than one family. Among the genes present in the regions reported here were involved in neurotransmission (GRM3, SIGMAR1, CHAT, and SLC18A3) and members of the HLA gene family (HLA-A, HLA-DPA1, and MICC). Conclusion The candidate regions identified in this study highlight the genetic diversity of ADHD. Upon further investigation, these loci may reveal candidate genes that enclose variants associated with ADHD. Although most ADHD studies were conducted in other populations, our study provides insight from an understudied, ethnically interesting population. PMID:28452824

2017-08-01

Faculty members are expected to write high-quality multiple-choice questions (MCQs) in order to accurately assess dental students' achievement. However, most dental school faculty members are not trained to write MCQs. Extensive faculty development programs have been used to help educators write better test items. The aim of this pilot study was to determine if a short workshop would result in improved MCQ item-writing by dental school faculty at one U.S. dental school. A total of 24 dental school faculty members who had previously written MCQs were randomized into a no-intervention group and an intervention group in 2015. Six previously written MCQs were randomly selected from each of the faculty members and given an item quality score. The intervention group participated in a training session of one-hour duration that focused on reviewing standard item-writing guidelines to improve in-house MCQs. The no-intervention group did not receive any training but did receive encouragement and an explanation of why good MCQ writing was important. The faculty members were then asked to revise their previously written questions, and these were given an item quality score. The item quality scores for each faculty member were averaged, and the difference from pre-training to post-training scores was evaluated. The results showed a significant difference between pre-training and post-training MCQ difference scores for the intervention group (p=0.04). This pilot study provides evidence that the training session of short duration was effective in improving the quality of in-house MCQs.

Reviewing program educational efforts is an important component of postgraduate medical education program accreditation. The post-graduate review process has evolved over time to include centralized oversight based on accreditation standards. The institutional review process and the impact on participating faculty are topics not well described in the literature. We conducted multiple Plan-Do-Study-Act (PDSA) cycles to identify and implement areas for change to improve productivity in our institutional program review committee. We also conducted one focus group and six in-person interviews with 18 committee members to explore their perspectives on the committee's evolution. One author (MLL) reviewed the transcripts and performed the initial thematic coding with a PhD level research associate and identified and categorized themes. These themes were confirmed by all participating committee members upon review of a detailed summary. Emergent themes were triangulated with the University of Michigan Medical School's Admissions Executive Committee (AEC). We present an overview of adopted new practices to the educational program evaluation process at the University of Michigan Health System that includes standardization of meetings, inclusion of resident members, development of area content experts, solicitation of committed committee members, transition from paper to electronic committee materials, and focus on continuous improvement. Faculty and resident committee members identified multiple improvement areas including the ability to provide high quality reviews of training programs, personal and professional development, and improved feedback from program trainees. A standing committee that utilizes the expertise of a group of committed faculty members and which includes formal resident membership has significant advantages over ad hoc or other organizational structures for program evaluation committees.

Although several studies have been conducted to investigate the relationship between perceived organizational support (POS) and job performance (JP), it remains unclear whether this relationship is appropriate for faculty members at Chinese universities. The objectives of this study were to (a) examine the correlation between POS andJP; (b) identify the predictors of POS, including demographic and organizational characteristics among faculty members at a Chinese university; (c) investigate the influence of mediating factors between POS and JP; and (d) compare the findings of this study with related studies. A cross-sectional questionnaire survey was used in this study. The questionnaire was administered to 700 faculty members who were randomly selected from all faculty members at six universities. A total of 581 questionnaires were obtained. A statistical model for JP was developed based on the literature review. The analysis results indicated that the relationship between POS and JP was mediated by job satisfaction (JS), positive affectivity (PA), and affective commitment (AC). In addition, procedural and distributive justice contribute to POS. The study concludes that the relationship between POS and JP is mediated by JS, PA, and AC and is influenced by POS. These results can provide evidence for university administrators to improve POS and increase the JP of faculty members at universities.

Disclosure of personal medical information: differences among parents and affected adults for genetic and nongenetic conditions.

Protecting the confidentiality of medical information has been an issue of great interest in the fields of bioethics, public policy, and law. Few empirical studies have addressed patient experiences and attitudes toward disclosure of private medical information in multiple contexts such as health insurance, employment, and the family. Furthermore, it is unclear whether differences exist in experiences and attitudes about privacy between those living with a serious medical condition versus those who have a child with a medical condition. The study sought to determine whether attitudes and experiences related to medical privacy and confidentiality differ between affected adults and parents of affected children. Interviews were conducted with 296 adults and parents of children with sickle cell disease (SCD), cystic fibrosis (CF), or diabetes mellitus (DM). This cross-sectional study collected data regarding their experiences, attitudes, and beliefs concerning medical privacy and confidentiality. Multinomial logistic regression analysis was conducted on quantitative data. Qualitative analysis was conducted on data from open-ended response items. Parents disclose their child's diagnosis to others more often than affected adults disclose their own disease status. Parents are less likely than affected adults to regret their disclosure, to hope others do not find out, to have been pressured to share information, and to be asked about their disease by employers. Affected adults express greater concern about disclosure, a greater prevalence and greater fear of discrimination, and experience greater pressure from family members to disclose. Clinicians and researchers working with these populations should consider these differences in privacy and disclosure. Further study is necessary to examine the implications of these differences in attitudes and experiences concerning insurance, employment, and social interactions among persons with these conditions.

Utilising family-based designs for detecting rare variant disease associations.

PubMed

Preston, Mark D; Dudbridge, Frank

2014-03-01

Rare genetic variants are thought to be important components in the causality of many diseases but discovering these associations is challenging. We demonstrate how best to use family-based designs to improve the power to detect rare variant disease associations. We show that using genetic data from enriched families (those pedigrees with greater than one affected member) increases the power and sensitivity of existing case-control rare variant tests. However, we show that transmission- (or within-family-) based tests do not benefit from this enrichment. This means that, in studies where a limited amount of genotyping is available, choosing a single case from each of many pedigrees has greater power than selecting multiple cases from fewer pedigrees. Finally, we show how a pseudo-case-control design allows a greater range of statistical tests to be applied to family data. © 2014 The Authors.

The devil is in the details: an analysis of the subtleties between phosphodiesterase inhibitors for erectile dysfunction.

PubMed

Smith-Harrison, L I; Patel, Abhishek; Smith, Ryan P

2016-04-01

Erectile dysfunction (ED) is a common sexual disorder with numerous etiologies involving multiple organ systems that leads to significant distress and decreased quality of life for the affected men. Fortunately, there are several modalities and interventions for treating ED. Oral medications, intra-urethral compounds, intracorporeal injections, vacuum-assist devices and surgically implanted prostheses are all part of the treatment algorithm. One of the first-lines and certainly the most widely used options for treating ED is the family of oral phosphodiesterase type 5 inhibitors (PDE5I). The introduction of these medications in the late 1990s revolutionized the field of sexual medicine. Currently there are no guidelines and minimal literature to help providers choose among drugs in this class. This review will address differences in efficacy and side effects between various members of the oral selective phosphodiesterase-5 inhibitor class of drugs.

The effects of collaboration and minimal-group membership on children's prosocial behavior, liking, affiliation, and trust.

Plötner, Maria; Over, Harriet; Carpenter, Malinda; Tomasello, Michael

2015-11-01

Recent theoretical work has highlighted potential links between interpersonal collaboration and group membership in the evolution of human sociality. Here we compared the effects of collaboration and minimal-group membership on young children's prosocial behavior (i.e., helping and resource allocation), liking, affiliation, and trust. In a design that matched as closely as possible these two ways of connecting with others, we showed that 5-year-olds' behavior was affected similarly by collaboration and minimal-group membership; both increased children's preference for their partners on multiple dimensions and produced overall effects of a similar magnitude. In contrast, 3.5-year-olds did not have a strong preference for either collaborators or minimal in-group members. Thus, both collaboration and minimal-group membership are similarly effective in their influence on children's prosocial behavior and social preferences. Copyright © 2015 Elsevier Inc.

Towards the social analysis of twinship.

PubMed

Stewart, E A

2000-12-01

The article examines the proposition that twinship is an irreducibly social phenomenon. Gender, age, birth order, socio-economic status and other variables are considered, along with the role of different patterns of socialization as these affect twinship. It is argued that, to a very large extent, from conception. through gestation, childbirth and subsequently childhood and adolescence, the social processing and regulation of social members take place in unitary terms and that therefore twins (and higher multiples) are an anomaly in relation to such processes. Twins' reactions to stigma, stereotyping and labelling are explored as an integral aspect of the social structuring of twinship. The role of the twin, as distinct from the role of the non-twin, is examined in the context of cultural expectations of twinship regarding similarity of identity and similarity of behaviour. Subsequent or concurrent processes of differentiation between twins are also examined. The article concludes with suggestions for further analyses of twinship.

The Social Context of Depression Symptomology in Sexual Minority Male Youth: Determinants of Depression in a Sample of Grindr Users.

Gibbs, Jeremy J; Rice, Eric

2016-01-01

The purpose of this study was to understand which social context factors most influence depression symptomology among sexual minority male youth (SMMY). In 2011, 195 SMMY who use Grindr were recruited to complete an online survey in Los Angeles, California. Items focused on social context variables and depression symptomology. Hierarchical multiple regressions were conducted using an ecological framework. The best fitting model accounted for 29.5% of the variance in depression. Experiences of homophobia, gay community connection, presence of an objecting network member, and emotional support were found to be significant predictors. Past experiences of homophobia continuing to affect youth indicates the need for intervention to reduction of homophobia in youths' social contexts. Interventions that teach youth skills to manage objecting viewpoints or help youth to reorganize their social networks may help to reduce the impact of an objecting network alter.

Quality of Life Perspectives of People With Amyotrophic Lateral Sclerosis and Their Caregivers.

PubMed

Johnson, Stephanie; Alonso, Bryant; Faulkner, Katie; Roberts, Haley; Monroe, Britton; Lehman, Leigh; Kearney, Pamalyn

This study explored differences in perspectives on quality of life (QOL) between people affected by amyotrophic lateral sclerosis (ALS) and their caregivers. QOL is often thought of as related to physical limitations, without consideration of other factors (e.g., cognitive, emotional) that may be stronger predictors of QOL in people with long-term degenerative diseases. Because QOL is complex and influenced by multiple factors, people with ALS and their caregivers may have different perspectives on what constitutes QOL. This study investigated potential discrepancies in QOL perspectives between people with ALS and their caregivers. Thirty dyads from the Augusta University Health ALS Clinic completed a measure of QOL, and we compared the results and identified patterns. The most prominent finding was that members of the dyads misunderstood the mental experiences of one another. Copyright © 2017 by the American Occupational Therapy Association, Inc.

Clinical profile of depressive disorder in children.

The aim of this retrospective study was to evaluate the risk factors, clinical features and co-morbid disorders of depressive disorder in children below the age of 12 years. Children who attended the child guidance clinic between January 2000 and December 2003 formed the subjects for the study. The diagnosis of depressive disorder was based on DSMIV diagnostic criteria for Major Depressive Disorder, Single episode. There were 26 boys and 19 girls. Stress at school and in the family was significantly associated with depressive disorder. Children with depressive disorder had significantly more family members affected with mental illnesses. The clinical features included diminished interest in play and activities, excessive tiredness, low self- esteem, problems with concentration, multiple somatic complaints, behavior symptoms like anger and aggression, recent deterioration in school performance and suicidal behavior. Majority of children had other associated psychiatric disorders which included dysthymic disorder, anxiety disorders, conduct disorder and conversion disorder.

The challenges of ageism in Brazil

PubMed Central

Goldani, Ana Maria

2013-01-01

The material and symbolic resource flows and obligations between generations leave an indelible imprint on family members. These intergenerational exchanges have increased in recent years with growing human longevity and they thus have become important to current academic and policy agendas. Concurrently, ageism and age discrimination have emerged as important subjects. The main goal of this article is to call attention to these issues and their relationship with the current policy debate on resource allocation by age groups. We argue that ageism and the practice of age discrimination in Brazil should be viewed as part of the multiple forms of discrimination experienced by individuals. While noticing someone’s age is not inherently offensive, acting on age-based stereotypes clearly works against the individual and often goes unchallenged by mainstream society. A central assumption in this paper is that the way we frame ageism and intergenerational relations significantly affects perceived age discrimination and support for age-based social programs.

International standards for brucellosis prevention and management.

PubMed

Ragan, V; Vroegindewey, G; Babcock, S

2013-04-01

International standards are a crucial element in brucellosis prevention and management. They allow policy-makers, scientists, epidemiologists, laboratories and trade entities to have a common vocabulary for communication and understanding of the disease. These standards cover the entire spectrum of activities from surveillance, testing, prophylaxis, transport and trade to policy development, research and reporting. Developing, adhering to and monitoring standards increases both the effectiveness and efficiency of prevention and management programmes. Creating standards with the input of all stakeholders ensures that the standards do not adversely affect the requirements of any of the multiple parties involved. The World Organisation for Animal Health (OIE), in conjunction with its Member Countries, and through its standing and ad hoc committees plus expert input, has taken a key leadership role in developing and reviewing brucellosis standards. These standards are used to harmonise testing, prevention processes, vaccines and reporting, to support trade and to protect human and animal health.

We present a case of a patient diagnosed with glioblastoma multiforme refractory to treatment. Glioblastoma multiforme is the most common primary brain tumour and unfortunately the most aggressive, with an estimated mortality of about 90% in the first year after diagnosis. In our case the patient had reached a stage of life where quality of life was importsnt, with palliative care being the only recourse. The family is the mainstay in the provision of care of terminally ill patients, and without their active participation it would be difficult to achieve the objectives in patient care. We must also consider the family of the terminally ill in our care aim, as its members will experience a series of changes that will affect multiple areas where we should take action.

Affect and Therapeutic Process in Groups for Chronically Mentally Ill Persons

PubMed Central

Stone, Walter N.

1998-01-01

A dynamic group treatment model for chronically ill persons allowing them to determine the frequency of attendance empowers the members and potentiates group development. This format respects patients' needs for space as represented by missed meetings. In this context, absences are formulated as self-protective and self-stabilizing acts rather than as resistance. In an accepting, supportive environment, members can be helped to explore affects and gain insight into their behaviors. A clinical example illustrates patients' examination of the meaning of missing and attending sessions, with particular focus on intensity of involvement, autonomy, and control. In the process of testing the therapist and group, members show capacity to gain insight into recent in-group and extra-group behaviors.(The Journal of Psychotherapy Practice and Research 1998; 7:208–216) PMID:9631342

DIFFERENT STROKES FOR DIFFERENT GANGS? AN ANALYSIS OF CAPITAL AMONG LATINO AND ASIAN GANG MEMBERS

PIH, KAY KEI-HO; DE LA ROSA, MARIO; RUGH, DOUGLAS; MAO, KUORAY

2009-01-01

Gang activity and membership were noted to be significantly related to financial rewards. As such, gang membership and gang activity should also be understood from an economic perspective. In this article, Pierre Bourdieu's framework of capital is used to analyze two separate samples of Latino and Asian gang members. Stark contrasts in socioeconomic backgrounds are recorded among the two samples of gang members, and gang membership and activities are also noticeably dissimilar. Accessibility to economic, cultural, and social capital is argued to affect gang membership and activities. The results suggest that the availability of legitimate and illegitimate capital greatly affects the trajectory and the length of gang involvement. Also, gangs provide significant material and social capital for the respondents of the study. PMID:19578563

Role of commitment to the supervisor, leader-member exchange, and supervisor-based self-esteem in employee-supervisor conflicts.

Landry, Guylaine; Vandenberghe, Christian

2009-02-01

Using survey data from 240 employees working in a variety of organizations, the authors examined the relations among commitment to the supervisor, leader-member exchange, supervisor-based self-esteem (SBSE), and relationship and substantive supervisor-subordinate conflicts. They found affective commitment was negatively related to both types of conflicts; perceived lack of alternatives commitment was positively related to relationship conflicts; and leader-member exchange was negatively related to substantive conflicts. SBSE was negatively associated with both types of conflicts. In addition, when SBSE was low, affective commitment was more strongly related to both types of conflicts, and normative commitment more strongly and positively related to substantive conflicts. The authors discuss the implications of these findings for the understanding of employee-supervisor conflicts.

Multiple Shocks, Coping and Welfare Consequences: Natural Disasters and Health Shocks in the Indian Sundarbans

2014-01-01

Background Based on a household survey in Indian Sundarbans hit by tropical cyclone Aila in May 2009, this study tests for evidence and argues that health and climatic shocks are essentially linked forming a continuum and with exposure to a marginal one, coping mechanisms and welfare outcomes triggered in the response is significantly affected. Data & Methods The data for this study is based on a cross-sectional household survey carried out during June 2010. The survey was aimed to assess the impact of cyclone Aila on households and consequent coping mechanisms in three of the worst-affected blocks (a sub-district administrative unit), viz. Hingalganj, Gosaba and Patharpratima. The survey covered 809 individuals from 179 households, cross cutting age and gender. A separate module on health-seeking behaviour serves as the information source of health shocks defined as illness episodes (ambulatory or hospitalized) experienced by household members. Key findings Finding reveals that over half of the households (54%) consider that Aila has dealt a high, damaging impact on their household assets. Result further shows deterioration of health status in the period following the incidence of Aila. Finding suggests having suffered multiple shocks increases the number of adverse welfare outcomes by 55%. Whereas, suffering either from the climatic shock (33%) or the health shock (25%) alone increases such risks by a much lesser extent. The multiple-shock households face a significantly higher degree of difficulty to finance expenses arising out of health shocks, as opposed to their counterparts facing only the health shock. Further, these households are more likely to finance the expenses through informal loans and credit from acquaintances or moneylenders. Conclusion This paper presented empirical evidence on how natural and health shocks mutually reinforce their resultant impact, making coping increasingly difficult and present significant risks of welfare loss, having short as well as long-run development manifestations.

The multi-instrumentalist hippocampus. Comment on "The quartet theory of human emotions: An integrative and neurofunctional model" by S. Koelsch et al.

NASA Astrophysics Data System (ADS)

Strange, Bryan A.; Yebra, Mar

2015-06-01

Characterizing the neural circuitry of emotion is important not only from a basic science perspective, but also for understanding how these circuits may malfunction in psychiatric disease. A fundamental question for affective neuroscience is whether there are specialised neuroanatomical areas, or "modules", dedicated to the processing of emotional stimuli. In their review, Koelsch and colleagues [1] argue for the existence of a quartet of neuroanatomically distinct cerebral systems involved in the generation of a specific class of affects. Intriguingly, all four systems (brainstem-, diencephalon-, hippocampus-, and orbitofrontal-centred) comprise brain areas whose role in emotional processing is in addition to mediating other specific aspects of cognition. One member of the quartet in which this is particularly apparent is the hippocampus, a structure known to be critical for episodic memory and navigation. If areas involved in emotion also mediate other brain functions, this raises an issue of whether these multiple functions are executed by segregated circuits within each structure - i.e., a "module" for emotion residing in a sub-division of a brain structure - or whether these circuits are superimposed.

Azadirachtin Affects the Growth of Spodoptera litura Fabricius by Inducing Apoptosis in Larval Midgut.

Azadirachtin, the environmentally friendly botanical pesticide, has been used as an antifeedant and pest growth regulator in integrated pest management for decades. It has shown strong biological activity against Spodoptera litura , but the mechanism of toxicity remains unclear. The present study showed that azadirachtin inhibited the growth of S. litura larvae, which was resulted by structure destroy and size inhibition of the midgut. Digital gene expression (DGE) analysis of midgut suggested that azadirachtin regulated the transcriptional level of multiple unigenes involved in mitogen-activated protein kinase (MAPK) and calcium apoptotic signaling pathways. Simultaneously, the expression patterns of some differentially expressed unigenes were verified by quantitative real time-PCR (qRT-PCR). In addition, the enhanced terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling (TUNEL) staining, the increased expression of caspase family members and apoptosis-binding motif 1 (IBM1) on both gene and protein level and the release of cytochrome c from mitochondria to cytoplasm were induced in midgut after azadirachtin treatment. These results demonstrated that azadirachtin induced structural alteration in S. litura larval midgut by apoptosis activation. These alterations may affect the digestion and absorption of nutrients and eventually lead to the growth inhibition of larvae.

2016-01-01

Hybrid organizations in modern health movements adopt multiple organizational logistics, allowing them to more effectively achieve social change. We conducted an analysis of 152 probreastfeeding organization websites categorized as institutionalized organizations, grassroots organizations, or hybrid organizations. Through a series of ANOVA analyses, we found that hybrid's websites provide significantly more useful health care information, better maintained dialogue with members, more efficiently mobilized members, commoditized health care issues less, and created member identity while maintaining institutional ties. Ultimately, hybrids tended to incorporate the positive elements from both grassroots and institutional organizations, while rejecting many of the negative elements.

To introduce a multiple-instructor, team-based, active-learning exercise to promote the integration of basic sciences (pathophysiology, pharmacology, and medicinal chemistry) and clinical sciences in a doctor of pharmacy curriculum. A team-based learning activity that involved pre-class reading assignments, individual-and team-answered multiple-choice questions, and evaluation and discussion of a clinical case, was designed, implemented, and moderated by 3 faculty members from the pharmaceutical sciences and pharmacy practice departments. Student performance was assessed using a multiple-choice examination, an individual readiness assurance test (IRAT), a team readiness assurance test (TRAT), and a subjective, objective, assessment, and plan (SOAP) note. Student attitudes were assessed using a pre- and post-exercise survey instrument. Students' understanding of possible correct treatment strategies for depression improved. Students were appreciative of this true integration of basic sciences knowledge in a pharmacotherapy course and to have faculty members from both disciplines present to answer questions. Mean student score on the on depression module for the examination was 80.4%, indicating mastery of the content. An exercise led by multiple instructors improved student perceptions of the importance of team-based teaching. Integrated teaching and learning may be achieved when instructors from multiple disciplines work together in the classroom using proven team-based, active-learning exercises.

Understanding Air Force members' intentions to participate in pro-environmental behaviors: an application of the theory of planned behavior.

2004-06-01

At a single installation, a cross section of 307 active duty Air Force members completed questionnaires to assess whether the theory of planned behavior was useful in explaining the service members' intentions to participate in three environmentally protective behaviors-recycling, carpooling, and energy conservation. While the individual tenets of the theory of planned behavior, i.e., attitude toward the behavior, subjective norms, and perceived control, accounted for differing amounts of variance in intentions, the results indicated that the intentions of these Air Force members to recycle, conserve energy, and carpool were moderately explained by the tenets of the theory of planned behavior collectively when the results of a multiple regression were analyzed.

To explore and describe how young adults between 18-25 years of age experienced growing up with a parent with multiple sclerosis and how these experiences continue to influence their daily lives. Chronic parental illness is occurring in about 10% of families worldwide, but little is known about how the children experience growing up with a parent with multiple sclerosis during their childhood and into young adulthood. We chose a qualitative design using a phenomenological approach based on Giorgi. Exploratory and open-ended interviews with 14 young adults were conducted. The essence of the phenomenon of having a parent with multiple sclerosis was synthesized into 'Striving for balance between caring and restraint' from two themes 'caring' and 'restraint' and eight subthemes. Participants' experiences of caring for parents with multiple sclerosis continued influencing their other close relationships, in which they tended to assume responsibility while concealing some of their feelings and desires. Most participants showed restraint among parents with and without multiple sclerosis, friends and partners. It seems that one of the greatest challenges of having a parent with multiple sclerosis is achieving a balance between caring for others and asserting one's own desires. Healthcare professionals can support the family by encouraging family members to participate in consultations and to assist the parents in providing information about multiple sclerosis and its symptoms to the children. Parents might need assistance in applying for help with domestic chores or referrals to support groups for their children or other family members. © 2016 John Wiley & Sons Ltd.

Science, new technology, patient care, dental reimbursement and government regulations all affect today's dental practitioners. To find out more about how such challenges may affect current private practitioners, the American Dental Association conducted the 2000 Membership Needs and Opinions Survey. A questionnaire was sent to 6,310 ADA members in January 2000 with follow-up mailings in February, March and April 2000. Data collection was completed in July 2000. The survey included questions on critical professional issues, and on perceptions of the ADA and ADA priorities. A total of 3,558 completed surveys were received for an adjusted response rate of 59.5 percent. Members rated the identified issues' level of importance to them. The top three issues included "maintaining my ability to recommend the treatment option I feel is most appropriate for my patients," "receiving fair reimbursement for the dental services I provide," and "protecting myself, my staff and my patients from communicable diseases." New dentists found other items to be more significant to them compared with members overall. Although ADA members as a whole had similar views on critical issues facing dentistry and ADA priorities, there were significant differences regarding some issues. New dentists were far more concerned about securing funds for their practice and paying off debt than were all ADA members. Minority dentists expressed greater levels of concern about certain issues than did all ADA members. When planning and implementing ADA activities, the Association should continue to take into account members' relative rankings of professional issues and note issues of special interest to selected membership subgroups.

Similar to members of the public, people with mental illness may exhibit general negative automatic prejudice against their own group. However, it is unclear whether more specific negative stereotypes are automatically activated among diagnosed individuals and how such automatic stereotyping may be related to self-reported attitudes and emotional reactions. We therefore studied automatically activated reactions toward mental illness among 85 people with schizophrenia, schizoaffective or affective disorders as well as among 50 members of the general public, using a Lexical Decision Task to measure automatic stereotyping. Deliberately endorsed attitudes and emotional reactions were assessed by self-report. Independent of diagnosis, people with mental illness showed less negative automatic stereotyping than did members of the public. Among members of the public, stronger automatic stereotyping was associated with more self-reported shame about a potential mental illness and more anger toward stigmatized individuals. Reduced automatic stereotyping in the diagnosed group suggests that people with mental illness might not entirely internalize societal stigma. Among members of the public, automatic stereotyping predicted negative emotional reactions to people with mental illness. Initiatives to reduce the impact of public stigma and internalized stigma should take automatic stereotyping and related emotional aspects of stigma into account. PMID:20843560

Purpose The purpose of this study was to investigate the behavioral effects of a theory-driven, mobile phone–based intervention that combines automated text messaging and remote nursing, using an automated, interactive text messaging system. Methods This was a mixed methods observational cohort study. Study participants were members of the University of Chicago Health Plan (UCHP) who largely reside in a working-class, urban African American community. Surveys were conducted at baseline, 3 months (mid-intervention), and 6 months (postintervention) to test the hypothesis that the intervention would be associated with improvements in self-efficacy, social support, health beliefs, and self-care. In addition, in-depth individual interviews were conducted with 14 participants and then analyzed using the constant comparative method to identify new behavioral constructs affected by the intervention. Results The intervention was associated with improvements in 5 of 6 domains of self-care (medication taking, glucose monitoring, foot care, exercise, and healthy eating) and improvements in 1 or more measures of self-efficacy, social support, and health beliefs (perceived control). Qualitatively, participants reported that knowledge, attitudes, and ownership were also affected by the program. Together these findings were used to construct a new behavioral model. Conclusions This study’s findings challenge the prevailing assumption that mobile phones largely affect behavior change through reminders and support the idea that behaviorally driven mobile health interventions can address multiple behavioral pathways associated with sustained behavior change.

Alcohol misuse among military service members from the recent conflicts in Iraq and Afghanistan is over two times higher compared to misuse in the civilian population. Unfortunately, in addition to experiencing personal consequences from alcohol misuse, partners and family members of alcohol-misusing service members also suffer in negative ways from their loved one's drinking. These family members represent important catalysts for helping their loved ones identify problem drinking and overcoming the barriers to seeking care. This paper describes the protocol to a pilot study evaluating a 4-session, web-based intervention (WBI) for concerned partners (CPs) of service members with alcohol misuse. The WBI will be adapted from the Community Reinforcement and Family Training (CRAFT) intervention. In the first phase, we will develop and beta-test the WBI with 15-20 CPs. In the second phase, we will randomize CPs to WBI (n = 50) or to delayed-WBI (n = 50) and evaluate the impact of the WBI on CPs' perceptions of service member help-seeking and drinking, as well as the CP's well-being and relationship satisfaction 3 months after the intervention. In the third phase, we will recruit 15-20 service members whose partners have completed the study. We will interview the service members to learn how the CP-focused WBI affected them and to assess whether they would be receptive to a follow-on WBI module to help them. This project has the potential to benefit a large population of military service members who may be disproportionately affected by recent conflicts and whose drinking misuse would otherwise go undetected and untreated. It also develops a new prevention model that does not rely on service members or partners attending a hospital or clinical facility to access care. NCT02073825.

In an era of competing priorities, funding is increasingly restricted for offices of faculty affairs and development. Opportunities for professional staff to grow and network through attendance at national meetings and to share best practices are limited. We sought to describe a community of practice established to enhance the professional development of faculty affairs professionals and to document its impact. We outlined the process of formation of the New England Network for Faculty Affairs (NENFA), reviewed the pedagogical approaches to professional development, and surveyed members to evaluate the impact of NENFA on their activities, professional network and their institutions. After a successful 2011 initial meeting, NENFA created an organizing committee and conducted a needs assessment among potential members. NENFA's charter, mission, goals, and structure were based on survey results. NENFA's regional community of practice grew to 31 institutions and held 10 meetings over 5 years. Meetings have examined a faculty development topic in depth using multiple learning formats to engage participants from academic medical centers and allied professions. Results from a 2015 member survey confirmed the value of NENFA. Multiple members documented changes in practice as a result of participating. NENFA has been sustained by volunteer leadership, collaboration, and the value that the group has brought to its members. We propose that a "community of practice" offers an effective model for collaborative learning among individuals at different institutions within a competitive health care environment. We recommend that the approach be replicated in other regions.

Investigation of Severe Craniomaxillofacial Battle Injuries Sustained by U.S. Service Members: A Case Series

2012-01-01

This case series describes craniomaxillofacial battle injuries, currently available surgical techniques, and the compromised outcomes of four service members who sustained severe craniomaxillofacial battle injuries in Iraq or Afghanistan. Demographic information, diagnostic evaluation, surgical procedures, and outcomes were collected and detailed with a follow-up of over 2 years. Reconstructive efforts with advanced, multidisciplinary, and multiple revision procedures were indicated; the full scope of conventional surgical options and resources were utilized. Patients experienced surgical complications, including postoperative wound dehiscence, infection, flap failure, inadequate mandibular healing, and failure of fixation. These complications required multiple revisions and salvage interventions. In addition, facial burns complicated reconstructive efforts by delaying treatment, decreasing surgical options, and increasing procedural numbers. All patients, despite multiple surgeries, continue to have functional and aesthetic deficits as a result of their injuries. Currently, no conventional treatments are available to satisfactorily reconstruct the face severely ravaged by explosive devices to an acceptable level, much less to natural form and function.

Disutility of illness for caregivers and families: a systematic review of the literature

Wittenberg, Eve; Prosser, Lisa A.

2013-01-01

Background Caring for an ill or disabled family member imposes a well-documented burden on the caregiver. The benefits of a health intervention may be underestimated if “spillover” effects on family members are not captured, resulting in inaccurate conclusions of economic evaluations. Objective To provide an estimate of, and to summarize measurement approaches for, the spillover disutility of illness on family members, relatives, and caregivers, through a systematic review of the literature. Methods The medical (PubMED), psychology (PsycINFO) and economics (EconLit) literatures were searched from inception through February, 2012 for published studies measuring spillover disutility of illness on family members and caregivers. Inclusion criteria were (1) studies using preference-based measures of health-related quality of life, and (2) studies reporting spillover disutility, or (3) studies reporting data from which a spillover disutility could be inferred. Results Fifteen studies were included in this review: 7 reported estimates of spillover disutility and 8 reporting data from which disutility could be inferred. Three studies found no disutility associated with spillover while 12 found measurable effects as large as −0.718 (and two found evidence of positive spillover in subsets of their samples). Generic (indirect) utility instruments were primarily used to measure spillover, including the EQ-5D, QWB and HUI (n=13), though two studies used modified versions of the time trade-off technique. Illnesses studied included childhood disorders (e.g., spina bifida, congenital malformations), diseases of the elderly (e.g., Alzheimer’s disease and dementia), physically disabling conditions (e.g., arthritis, multiple sclerosis), and medical conditions such as cancer and stroke. The persons affected by spillover included parents, grandparents, spouses/partners, other family caregivers, and household members. Conclusions There is a limited literature on the spillover disutility of illness on family members and caregivers, providing some specific estimates of a generally small, negative effect for particular conditions and individuals. Measurement methods vary across studies and a consensus approach has not yet been reached. Evidence suggests that the inclusion of spillover effects in economic evaluations would increase the relative effectiveness of interventions that address conditions with spillover compared to those without, though such differential benefits may be limited to such specific circumstances.

2016-06-01

The purpose of this study was to examine correlations between nurses' self-leadership and individual work role performance and correlations between self-leadership in nursing units and team members' work role performance. Participants were 202 conveniently selected general nurses from 5 general hospitals in Korea. The study was carried out on 35 nursing units. Data were collected during February 2015 with self-report questionnaires. For factors affecting individual work role performance, self-expectation, self-goal setting, constructive thought, clinical career in the present nursing unit and marital status accounted for 44.0% of proficiency, while self-expectation, self-goal setting, constructive thought, and marital status accounted for 42.3% of adaptivity. Self-expectation, self-goal setting, constructive thought, self-reward, clinical career in the present nursing unit and position accounted for 26.4% of proactivity. In terms of team members' work role performance, self-reward and self-expectation in nursing units explained 29.0% of team members' proficiency. Self-reward and self-expectation in nursing units explained 31.6% of team members' adaptivity, and self-reward in nursing units explained 16.8% of team members' proactivity. The results confirm that nurses' self-leadership affects not only individual self-leadership but also team members' work role performance. Accordingly, to improve nurses' work role performance in nursing units of nursing organizations, improvement in nursing environment based on self-leadership education is necessary and nurses' tasks rearranged so they can appreciate work-autonomy and challenges of work.

The motor control of bimanual coordination and motor speech was compared between first degree relatives from families with at least 2 dyslexic family members, and families where probands were the only affected family members. Half of affected relatives had motor coordination deficits; and they came from families in which probands also showed impaired motor coordination. By contrast, affected relatives without motor deficits came from dyslexia families where probands did not have motor deficits. Motor coordination deficits were more common and more severe among affected offspring in families where both parents were affected than among affected offspring in families where onlymore » one parent was affected. However, motor coordination deficits were also more common and more severe in affected parents when both parents were affected than among affected parents in families where only one parent was affected. We conclude that impaired temporal resolution in motor action identifies a behavioral phenotype in some subtypes of developmental dyslexia. The observed pattern of transmission for motor deficits and reading impairment in about half of dyslexia families was most congruent with a genetic model of dyslexia in which 2 codominant major genes cosegregate in dyslexia pedigrees where the proband is also motorically impaired. 54 refs., 5 figs., 5 tabs.« less

Psychological response of family members of patients hospitalised for influenza A/H1N1 in Oaxaca, Mexico.

The A/H1N1 pandemic originated in Mexico in April 2009, amid high uncertainty, social and economic disruption, and media reports of panic. The aim of this research project was to evaluate the psychological response of family primary caregivers of patients hospitalised in the Intensive Care Unit (ICU) with suspected influenza A/H1N1 to establish whether there was empirical evidence of high adverse psychological response, and to identify risk factors for such a response. If such evidence was found, a secondary aim was to develop a specific early intervention of psychological support for these individuals, to reduce distress and possibly lessen the likelihood of post-traumatic stress disorder (PTSD) in the longer term. Psychological assessment questionnaires were administered to the family primary caregivers of patients hospitalised in the ICU in the General Hospital of Zone 1 of the Mexican Institute for Social Security (IMSS), Oaxaca, Mexico with suspected influenza A/H1N1, during the month of November 2009. The main outcome measures were ratings of reported perceived stress (PSS-10), depression (CES-D), and death anxiety (DAQ). Data were subjected to simple and multiple linear regression analysis to identify risk factors for adverse psychological response. Elevated levels of perceived stress and depression, compared to population normative data, and moderate levels of death anxiety were noted. Levels of depression were similar to those found in comparable studies of family members of ICU patients admitted for other conditions. Multiple regression analysis indicated that increasing age and non-spousal family relationship were significantly associated with depression and perceived stress. Female gender, increasing age, and higher levels of education were significantly associated with high death anxiety. Comparisons with data collected in previous studies in the same hospital ICU with groups affected by a range of other medical conditions indicated that the psychological response reported in this study was generally lower. Data indicated that, contrary to widely publicised reports of 'panic' surrounding A/H1N1, that some of those most directly affected did not report excessive psychological responses; however, we concluded that there was sufficient evidence to support provision of limited psychological support to family caregivers.

Using multiple scattering theory, the T matrix of a pair of scatterers which takes all back-and-forth scattering between the pair members into account and considers multiple scattering effects in the intensity calculation is used to calculate the magnitude and the width of the backscattered intensity peak. Generally, at low concentrations, both the magnitude of the scattered intensity and multiple scattering contributions are not sufficiently strong to reach the enhanced-backscattering threshold. The results obtained are consistent with those yielded by optical experiments.

Value, Challenges, and Satisfaction of Certification for Multiple Sclerosis Specialists

Halper, June

2014-01-01

Background: Specialist certification among interdisciplinary multiple sclerosis (MS) team members provides formal recognition of a specialized body of knowledge felt to be necessary to provide optimal care to individuals and families living with MS. Multiple sclerosis specialist certification (MS Certified Specialist, or MSCS) first became available in 2004 for MS interdisciplinary team members, but prior to the present study had not been evaluated for its perceived value, challenges, and satisfaction. Methods: A sample consisting of 67 currently certified MS specialists and 20 lapsed-certification MS specialists completed the following instruments: Perceived Value of Certification Tool (PVCT), Perceived Challenges and Barriers to Certification Scale (PCBCS), Overall Satisfaction with Certification Scale, and a demographic data form. Results: Satisfactory reliability was shown for the total scale and four factored subscales of the PVCT and for two of the three factored PCBCS subscales. Currently certified MS specialists perceived significantly greater value and satisfaction than lapsed-certification MS specialists in terms of employer and peer recognition, validation of MS knowledge, and empowering MS patients. Lapsed-certification MS specialists reported increased confidence and caring for MS patients using evidence-based practice. Both currently certified and lapsed-certification groups reported dissatisfaction with MSCS recognition and pay/salary rewards. Conclusions: The results of this study can be used in efforts to encourage initial certification and recertification of interdisciplinary MS team members. PMID:25061432

Objectives: To characterize clinically and genetically a family with autosomal dominant lateral temporal epilepsy (ADLTE) negative to LGI1 exon sequencing test. Methods: All participants were personally interviewed and underwent neurologic examination. Most affected subjects underwent EEG and neuroradiologic examinations (CT/MRI). Available family members were genotyped with the HumanOmni1-Quad v1.0 single nucleotide polymorphism (SNP) array beadchip and copy number variations (CNVs) were analyzed in each subject. LGI1 gene dosage was performed by real-time quantitative PCR (qPCR). Results: The family had 8 affected members (2 deceased) over 3 generations. All of them showed GTC seizures, with focal onset in 6 and unknown onset in 2. Four patients had focal seizures with auditory features. EEG showed only minor sharp abnormalities in 3 patients and MRI was unremarkable in all the patients examined. Three family members presented major depression and anxiety symptoms. Routine LGI1 exon sequencing revealed no point mutation. High-density SNP array CNV analysis identified a genomic microdeletion about 81 kb in size encompassing the first 4 exons of LGI1 in all available affected members and in 2 nonaffected carriers, which was confirmed by qPCR analysis. Conclusions: This is the first microdeletion affecting LGI1 identified in ADLTE. Families with ADLTE in which no point mutations are revealed by direct exon sequencing should be screened for possible genomic deletion mutations by CNV analysis or other appropriate methods. Overall, CNV analysis of multiplex families may be useful for identifying microdeletions in novel disease genes. PMID:22496201

The effect of families on the process of outpatient visits in family practice.

Main, D S; Holcomb, S; Dickinson, P; Crabtree, B F

2001-10-01

Our goal was to describe how physician knowledge of patients' families affects the processes of patient care in family practices. Using a multimethod comparative case study design, detailed dictated field notes were recorded after direct observation of patient encounters and the office environment as part of the Prevention and Competing Demands in Primary Care Study. We identified domains of outpatient visits in which patients were accompanied by a family member or in which family-oriented content was discussed. Outpatient encounters with 1637 patients presenting in 18 family practices in the Midwest were analyzed using an editing style. We developed a typology for ways in which family context affects outpatient visits. Patients were accompanied during 35% of all outpatient visits, the vast majority of these visits involving children. Family history or a family member's problems were discussed during 35% of visits during which no family member was present. An analysis of these "family-oriented" visits resulted in a typology of 6 ways that family context informs and affects the outpatient visit: (1) using family social context to illuminate patient disease, illness, and health; (2) using family to discover the source of an illness; (3) discussing and managing the health and illness of family members; (4) family concern for patient's health; (5) using the family as a care resource and care collaborator; and, (6) giving family members unscheduled care. Family context is an important feature of family practice that influences the processes of patient care. Since family-oriented care is an essential feature of family practice, outcomes of this largely hidden part of care deserve further study.

The evaluations on institutionalized care facilities from family members, after their loved ones moved into such services, are very different from culture to culture, family to family and person to person. According to a recent survey in the United States and China, it is found that different cultures and the different health conditions of the residents strongly influence family member's viewpoints on institutionalized care services. It is also found that the availability of the institutionalized care facilities plays a significant role, which strongly affects family members' evaluations on nursing home services.

Fewer but better: Proportionate size of the group affects evaluation of transgressive leaders.

A group may be badly affected if its leader transgresses important rules. Nonetheless, an emerging body of evidence suggests that in intergroup contexts, group members apply a double standard when judging ingroup leaders - They respond less punitively to transgressions by their leader than by non-leaders. In this article, two experiments investigated how proportionate ingroup size affects reactions to transgressive ingroup leaders. We demonstrate that ingroup leaders from larger, but not smaller, groups benefit from the double standard. The experiments testing the effects of two different types of transgressions (nepotistic favouritism and corruption, respectively) show that transgressive leaders from larger groups are evaluated more positively than both comparable non-leaders and leaders from smaller groups. In contrast, transgressive leaders from smaller groups are evaluated similarly to comparable transgressive non-leaders. Experiment 2 investigated a potential explanation for this phenomenon. Faced with a transgressive leader, members of a smaller group report greater embarrassment than do members of larger groups in relation to the leaders' actions. Implications of these findings and directions for future research are discussed. © 2015 The British Psychological Society.

The authors argue that over time the difference between team members' perception of the organizational support received by the team (or team climate for organizational support) and their manager's perception of the organizational support received by the team has an effect on important outcomes and emergent states, such as team performance and team positive and negative affect above and beyond the main effects of climate perceptions themselves. With a longitudinal sample of 179 teams at Time 1 and 154 teams at Time 2, the authors tested their predictions using a combined polynomial regression and response surface analyses approach. The results supported the authors' predictions. When team managers and team members' perceptions of organizational support were high and in agreement, outcomes were maximized. When team managers and team members disagreed, team negative affect increased and team performance and team positive affect decreased. The negative effects of disagreement were most amplified when managers perceived that the team received higher levels of support than did the team itself.

[The role of university hospital executive board members].

Demographic changes and medical progress in combination with vastly altered regulatory and economic environments have forced considerable change in the structure of German university hospitals in recent years. These changes have affected medical care as well as research and medical school training. To allow for more flexibility and a higher level of reactivity to the changing environment German university hospitals were transferred from state agencies to independent corporate structures. All but one remains wholly owned by the respective state governments. The governing structure of these independent medical hospitals consists of an executive board, generally made up of a medical director, a financial director, a director for nursing, and the dean of the medical faculty. In most hospitals, the medical director serves as chief executive officer. The regulations governing the composition and responsibility of the members of the executive board differ from state to state. These differences do affect to some degree the interactive effectiveness of the members of the executive boards. Modalities that stress the overall responsibility for all board members seem to work better than those that define clear portfolio limits. Even more than organizational and regulatory differences, the effectiveness of the work of the executive boards is influenced by the personality of the board members themselves. Success appears to be a clear function of the willingness of all members to work together.

The relationship between job performance and perceived organizational support in faculty members at Chinese universities: a questionnaire survey

PubMed Central

2014-01-01

Background Although several studies have been conducted to investigate the relationship between perceived organizational support (POS) and job performance (JP), it remains unclear whether this relationship is appropriate for faculty members at Chinese universities. The objectives of this study were to (a) examine the correlation between POS andJP; (b) identify the predictors of POS, including demographic and organizational characteristics among faculty members at a Chinese university; (c) investigate the influence of mediating factors between POS and JP; and (d) compare the findings of this study with related studies. Methods A cross-sectional questionnaire survey was used in this study. The questionnaire was administered to 700 faculty members who were randomly selected from all faculty members at six universities. A total of 581 questionnaires were obtained. A statistical model for JP was developed based on the literature review. Results The analysis results indicated that the relationship between POS and JP was mediated by job satisfaction (JS), positive affectivity (PA), and affective commitment (AC). In addition, procedural and distributive justice contribute to POS. Conclusions The study concludes that the relationship between POS and JP is mediated by JS, PA, and AC and is influenced by POS. These results can provide evidence for university administrators to improve POS and increase the JP of faculty members at universities. PMID:24624932

Most dementia research investigates the social context of declining ability through studies of decision-making around medical treatment and end-of-life care. This study seeks to fill an important gap in research about how family members manage the risks of functional decline at home. Drawing on three waves of in-depth interviewing in 2012-2014, it investigates how family members in US households manage decline in an affected individual's natural range of daily activities over time. The findings show that early on in the study period affected individuals were perceived to have awareness of their decline and routinely drew on family members for support. Support transformed when family members detected that the individual's deficit awareness had diminished, creating a corresponding increase in risk of self-harm around everyday activities. With a loss of confidence in the individual's ability to regulate his or her own activities to avoid these risks, family members employed unilateral practices to manage the individual's autonomy around his or her activity involvements. These practices typically involved various deceits and ruses to discourage elders from engaging in activities perceived as potentially dangerous. The study concludes by discussing the implications that the social context of interpretive work around awareness and risk plays an important role in how families perceive an elder's functional ability and manage his or her activity involvements.

1996-10-22

A multiple capillary biochemical analyzer is disclosed for sequencing DNA and performing other analyses, in which a set of capillaries extends from wells in a microtiter plate into a cuvette. In the cuvette the capillaries are held on fixed closely spaced centers by passing through a sandwich construction having a pair of metal shims which squeeze between them a rubber gasket, forming a leak proof seal for an interior chamber in which the capillary ends are positioned. Sheath fluid enters the chamber and entrains filament sample streams from the capillaries. The filament sample streams, and sheath fluid, flow through aligned holes in a barrier member spaced close to the capillary ends, into a collection chamber having a lower glass window. The filament streams are illuminated above the barrier member by a laser, causing them to fluoresce. The fluorescence is viewed end-on by a CCD camera chip located below the glass window. The arrangement ensures an equal optical path length from all fluorescing spots to the CCD chip and also blocks scattered fluorescence illumination, providing more uniform results and an improved signal-to-noise ratio. 12 figs.

Relationship development is crucial to nursing practice with families. However, little is known about the process of building relationships with multiple family members in home care settings and in various cultures. The objective of this study was to explore the experiences of home care nurses about how they established relationships with older clients and their families in Japan. Grounded theory was used to guide the research. Twenty-three expert home care nurses participated in semistructured interviews concerning their family nursing practice. The establishment of relationships with clients/family members was based on a purposeful yet nonimposing approach composed of four aspects: keeping a mindful distance from the family, not being a threat to family life, being a comfortable neighbor, and gaining trust as a competent nurse. Through a purposeful nonimposing approach, Japanese home care nurses promoted and nurtured nurse-family relationships and became involved in the life of the family. These findings provide a useful foundation to guide practice with families and grow knowledge about the process of establishing relationships with multiple family members in home settings.

The standard dual-component and two-member linear mixing model is often used to quantify water mixing of different sources. However, it is no longer applicable whenever actual mixture concentrations are not exactly known because of dilution. For example, low-water-content (low-porosity) rock samples are leached for pore-water chemical compositions, which therefore are diluted in the leachates. A multicomponent, two-member mixing model of dilution has been developed to quantify mixing of water sources and multiple chemical components experiencing dilution in leaching. This extended mixing model was used to quantify fracture-matrix interaction in construction-water migration tests along the Exploratory Studies Facility (ESF) tunnel at Yucca Mountain, Nevada, USA. The model effectively recovers the spatial distribution of water and chemical compositions released from the construction water, and provides invaluable data on the matrix fracture interaction. The methodology and formulations described here are applicable to many sorts of mixing-dilution problems, including dilution in petroleum reservoirs, hydrospheres, chemical constituents in rocks and minerals, monitoring of drilling fluids, and leaching, as well as to environmental science studies.

Familial occurrence of cervical artery dissection--coincidence or sign of familial predisposition?

BACKGROUNDAND PURPOSE: The etiology of spontaneous cervical artery dissection (CeAD) is poorly understood in most patients. Mild cervical trauma preceding the dissection event is a common finding, but many CeAD occur spontaneously. It is likely that genetic factors may increase the risk for CeAD. However, familial cases are excedingly rare. Familial clustering of CeAD may be accidental or associated with genetic or environmental risk factors shared between affected relatives. In this explorative study, we aim to show that specific risk factors for familial CeAD exist. Age of onset, sex, affected artery and number of recurrent CeAD were documented for familial patients and compared with published findings from patients with sporadic CeAD. Concordance of age, sex and dissected artery within the families was analyzed by correlation analysis and by analysis of variance or Kruskal-Wallis testing. The study sample consisted of 9 new patients with a family history of CeAD enrolled in the Neurology Department of the University of Heidelberg or referred to Heidelberg from other centers. The study sample also included published findings from another 23 patients, in total 32 patients. The mean age of the patients with familial CeAD at their first dissections was 38.4 ± 13.3 years. Twenty (62.5%) patients were female and 12 patients (37.5%) suffered multiple dissections. Four patients (12.5%) presented with recurrent dissections after >1 year. Patients with a familial history of CeAD were younger (p = 0.023) and presented more often with multiple dissections (p = 0.024) and recurrent dissections (p = 0.018). Age at the first event (correlation analysis p = 0.026; analysis of variance p = 0.029) and site of the dissection (correlation analysis p = 0.032; Kruskal-Wallis test p = 0.018) differed between the families, and there was no concordance of gender of affected family members (correlation analysis p = 0.500; Kruskal-Wallis test p = 0.211). The high prevalence of multiple dissection events and of long-term (>1 year) recurrent dissections in patients with a familial history of CeAD indicates that a specific predisposition for familial CeAD exists. Since age of onset and affected vessel differ between families, the risk profile for familial CeAD is heterogeneous. A large-scale (whole exome) sequencing analysis of 14 patients from 7 of the analyzed families is currently being performed in order to identify causative genetic variants. Copyright © 2012 S.

JUN regulates early transcriptional responses to axonal injury in retinal ganglion cells.

PubMed

Fernandes, Kimberly A; Harder, Jeffrey M; Kim, Jessica; Libby, Richard T

2013-07-01

The AP1 family transcription factor JUN is an important molecule in the neuronal response to injury. In retinal ganglion cells (RGCs), JUN is upregulated soon after axonal injury and disrupting JUN activity delays RGC death. JUN is known to participate in the control of many different injury response pathways in neurons, including pathways controlling cell death and axonal regeneration. The role of JUN in regulating genes involved in cell death, ER stress, and regeneration was tested to determine the overall importance of JUN in regulating RGC response to axonal injury. Genes from each of these pathways were transcriptionally controlled following axonal injury and Jun deficiency altered the expression of many of these genes. The differentially expressed genes included, Atf3, Ddit3, Ecel1, Gadd45α, Gal, Hrk, Pten, Socs3, and Sprr1a. Two of these genes, Hrk and Atf3, were tested for importance in RGC death using null alleles of each gene. Disruption of the prodeath Bcl2 family member Hrk did not affect the rate or amount of RGC death after axonal trauma. Deficiency in the ATF/CREB family transcription factor Atf3 did lessen the amount of RGC death after injury, though it did not provide long term protection to RGCs. Since JUN's dimerization partner determines its transcriptional targets, the expression of several candidate AP1 family members were examined. Multiple AP1 family members were induced by axonal injury and had a different expression profile in Jun deficient retinas compared to wildtype retinas (Fosl1, Fosl2 and Jund). Overall, JUN appears to play a multifaceted role in regulating RGC response to axonal injury. Copyright © 2013 Elsevier Ltd. All rights reserved.

Study was case study at Pamekasan Regency of Madura Island, East Java, Indonesia. The research aimed to examine income of smallholder beef cattle farming and its influencing factors. The research used 30 members of the Pancong Jaya group farmer that obtained by purposive sampling method. Research regarded descriptive analysis using economic formulation and multiple regression technique. Results found that R2 Adjusted obtained 73.70% and F-calculation (12.625) indicated significant (P< 0.000). Partial analysis confirmed that five out of nine variables have effected on the beef cattle farming income. Farmer’s experience in raising cattle and their education revealed a positive and high significant (P< 0.000 and P<0.005, respectively), associated with the farm earning. Farmer’s age, the number of household members, and purchasing breeding stock appeared a negative and significant (P <0.05) and (P<0.1, accordingly) influence on farmer’s income. This study concluded that producing per AU cattle required capital approximately IDR 16,861,718 (structured by 59.99% of fixed and 40.01 % of working capital) and IDR 6,745,512 of production costs (composed by 57.47% of feeder cattle procurement, 17.78% of feed concentrate and 14.48 % of forage expenses) to obtain IDR 8,834 of revenue and IDR 2,089,512 of income. The efficient beef cattle farming also existed in corresponding with 1.31 of R/C Ratio. Farmers’ education and experience in handling cattle strongly influenced on increasing income. However, the contrast view come from farmers’ age, the number of family members, and purchasing feeder cattle in which these seemed to reduce farmers’ income.

Twenty-seven nursing home patients with mid- to late-stage dementia participated in a study of the relation between preillness personality, as indexed by attachment and emotion regulation style, and current emotional behavior. Preillness measures were completed by family members and current assessments of emotion were supplied by nursing home aides and family members; in addition, emotion was coded during a family visit using an objective coding system for facial emotion expressions. Attachment style was found to be related to the expression of positive affect, with securely attached individuals displaying more positive affect than avoidantly attached individuals. In addition, high ratings on premorbid hostility were associated with higher rates of negative affect and lower rates of positive affect. These findings indicate that premorbid aspects of personality show continuity over time, even in mid- to late-stage dementia.

Irregular chiasm-C-roughest, a member of the immunoglobulin superfamily, affects sense organ spacing on the Drosophila antenna by influencing the positioning of founder cells on the disc ectoderm.

We describe a role for Irregular chiasmC-roughest (IrreC-rst), an immunoglobulin (Ig) superfamily member, in patterning sense organs on the Drosophila antenna. IrreC-rst protein is initially expressed homogeneously on apical profiles of ectodermal cells in regions of the antennal disc. During specification of founder cells (FCs), the intracellular protein distribution changes and becomes concentrated in regions where specific intercellular contacts presumably occur. Loss of function mutations as well as misexpression of irreC-rst results in an altered arrangement of FCs within the disc compared to wildtype. Sense organ development occurs normally, although spacing is affected. Unlike its role in interommatidial spacing, irreC-rst does not affect apoptosis during antennal development. We propose that IrreC-rst affects the spatial relationship between sensory and ectodermal cells during FC delamination.

To investigate factors affecting willingness to pay (WTP) for health insurance of older adults in a longitudinal setting in Germany. Survey data from a cohort study in Saarland, Germany, from 2008-2010 and 2011-2014 (n 1  = 3,124; n 2  = 2,761) were used. Panel data were taken at two points from an observational, prospective cohort study. WTP estimates were derived using a contingent valuation method with a payment card. Participants provided data on sociodemographics, lifestyle factors, morbidity, and health care utilization. Fixed effects regression models showed higher individual health care costs to increase WTP, which in particular could be found for members of private health insurance. Changes in income and morbidity did not affect WTP among members of social health insurance, whereas these predictors affected WTP among members of private health insurance. The fact that individual health care costs affected WTP positively might indicate that demanding (expensive) health care services raises the awareness of the benefits of health insurance. Thus, measures to increase WTP in old age should target at improving transparency of the value of health insurances at the moment when individual health care utilization and corresponding costs are still relatively low. © Health Research and Educational Trust.

Housing instability has been shown to be related to poorer health outcomes in various studies, mainly in the USA and UK. Affected individuals are more prone to psychiatric (e.g., major depression, anxiety) and physical disorders (e.g., hypertension). This situation has deteriorated with the onset of the economic crisis. One of the most affected countries is Spain, which has high rates of foreclosure and eviction that continue to rise. In response, a civil movement, The Platform for People Affected by Mortgages (PAH), works to provide solutions to its members affected by foreclosure and advocates for the right to decent housing. The aims of this study ware to describe and compare the health status of PAH members from Catalonia to a sample of the general population and to analyze the association between health status and mortgage status, foreclosure stage, and other socioeconomic variables, among members of the PAH. We conducted a cross-sectional study using a self-administered online questionnaire (2014) administered to 905 PAH members in Catalonia (>18 years; 559 women and 346 men). Results were compared with health indicators from The Health Survey of Catalonia 2013 (n = 4830). The dependent variables were poor mental health (GHQ 12 ≥ 3), and poor self-reported health (fair or poor). All analyses were stratified by sex. We computed age-standardized prevalence and prevalence ratios of poor mental and self-reported health in both samples. We also analyzed health outcomes among PAH members according to mortgage status (mortgage holders or guarantors), stage of foreclosure, and other socioeconomic variables by computing prevalence ratios from robust Poisson regression models. The prevalence of poor mental health among PAH members was 90.6 % in women and 84.4 % in men, and 15.5 and 10.2 % in the general population, respectively. The prevalence of poor self-reported health was 55.6 % in women and 39.4 % in men from the PAH, and 19.2 and 16.1 % in the general population, respectively. These health inequalities were independent of socioeconomic status. The prevalence of poor mental health was higher among individuals in the non-payment stage of foreclosure than among those who were up to date with their payments (e.g., PRc = 1.16 [95 % CI 1.04-1.28]). In contrast, self-reported poor health was more prominent in later stages of foreclosure, such as in post-eviction without dation in payment stage in men (PRc = 2.24 [95 %CI = 1.35-3.72]). We observed a considerably higher prevalence of poor mental and self-reported health among male and female PAH members than in the general population. Public policies that tackle housing instability and its consequences are urgently needed in Spain.

A stacking ensemble learning framework for annual river ice breakup dates

2018-06-01

River ice breakup dates (BDs) are not merely a proxy indicator of climate variability and change, but a direct concern in the management of local ice-caused flooding. A framework of stacking ensemble learning for annual river ice BDs was developed, which included two-level components: member and combining models. The member models described the relations between BD and their affecting indicators; the combining models linked the predicted BD by each member models with the observed BD. Especially, Bayesian regularization back-propagation artificial neural network (BRANN), and adaptive neuro fuzzy inference systems (ANFIS) were employed as both member and combining models. The candidate combining models also included the simple average methods (SAM). The input variables for member models were selected by a hybrid filter and wrapper method. The performances of these models were examined using the leave-one-out cross validation. As the largest unregulated river in Alberta, Canada with ice jams frequently occurring in the vicinity of Fort McMurray, the Athabasca River at Fort McMurray was selected as the study area. The breakup dates and candidate affecting indicators in 1980-2015 were collected. The results showed that, the BRANN member models generally outperformed the ANFIS member models in terms of better performances and simpler structures. The difference between the R and MI rankings of inputs in the optimal member models may imply that the linear correlation based filter method would be feasible to generate a range of candidate inputs for further screening through other wrapper or embedded IVS methods. The SAM and BRANN combining models generally outperformed all member models. The optimal SAM combining model combined two BRANN member models and improved upon them in terms of average squared errors by 14.6% and 18.1% respectively. In this study, for the first time, the stacking ensemble learning was applied to forecasting of river ice breakup dates, which appeared promising for other river ice forecasting problems.

Revised Lithostratigraphy of the Sonsela Member (Chinle Formation, Upper Triassic) in the Southern Part of Petrified Forest National Park, Arizona

Martz, Jeffrey W.; Parker, William G.

2010-01-01

Background Recent revisions to the Sonsela Member of the Chinle Formation in Petrified Forest National Park have presented a three-part lithostratigraphic model based on unconventional correlations of sandstone beds. As a vertebrate faunal transition is recorded within this stratigraphic interval, these correlations, and the purported existence of a depositional hiatus (the Tr-4 unconformity) at about the same level, must be carefully re-examined. Methodology/Principal Findings Our investigations demonstrate the neglected necessity of walking out contacts and mapping when constructing lithostratigraphic models, and providing UTM coordinates and labeled photographs for all measured sections. We correct correlation errors within the Sonsela Member, demonstrate that there are multiple Flattops One sandstones, all of which are higher than the traditional Sonsela sandstone bed, that the Sonsela sandstone bed and Rainbow Forest Bed are equivalent, that the Rainbow Forest Bed is higher than the sandstones at the base of Blue Mesa and Agate Mesa, that strata formerly assigned to the Jim Camp Wash beds occur at two stratigraphic levels, and that there are multiple persistent silcrete horizons within the Sonsela Member. Conclusions/Significance We present a revised five-part model for the Sonsela Member. The units from lowest to highest are: the Camp Butte beds, Lot's Wife beds, Jasper Forest bed (the Sonsela sandstone)/Rainbow Forest Bed, Jim Camp Wash beds, and Martha's Butte beds (including the Flattops One sandstones). Although there are numerous degradational/aggradational cycles within the Chinle Formation, a single unconformable horizon within or at the base of the Sonsela Member that can be traced across the entire western United States (the “Tr-4 unconformity”) probably does not exist. The shift from relatively humid and poorly-drained to arid and well-drained climatic conditions began during deposition of the Sonsela Member (low in the Jim Camp Wash beds), well after the Carnian-Norian transition.

To characterize the clinical and molecular genetic characteristics of a large, multigenerational Chinese family showing different phenotypes. A pedigree consisted of 56 individuals in 5 generations was recruited. Comprehensive ophthalmic examinations were performed in 16 family members affected. Mutation screening of CYP4V2 was performed by Sanger sequencing. Next-generation sequencing (NGS) was performed to capture and sequence all exons of 47 known retinal dystrophy-associated genes in two affected family members who had no mutations in CYP4V2 . The detected variants in NGS were validated by Sanger sequencing in the family members. Two compound heterozygous CYP4V2 mutations (c.802-8_810del17insGC and c.992A>C) were detected in the proband who presented typical clinical features of BCD. One missense mutation (c.1482C>T, p.T494M) in the PRPF3 gene was detected in 9 out of 22 affected family members who manifested classical clinical features of RP. Our results showed that two compound heterozygous CYP4V2 mutations caused BCD, and one missense mutation in PRPF3 was responsible for adRP in this large family. This study suggests that accurate phenotypic diagnosis, molecular diagnosis, and genetic counseling are necessary for patients with hereditary retinal degeneration in some large mutigenerational family.

A method of forming a textured superconductor wire includes constraining an elongated superconductor precursor between two constraining elongated members placed in contact therewith on opposite sides of the superconductor precursor, and passing the superconductor precursor with the two constraining members through flat rolls to form the textured superconductor wire. The method includes selecting desired cross-sectional shape and size constraining members to control the width of the formed superconductor wire. A textured superconductor wire formed by the method of the invention has regular-shaped, curved sides and is free of flashing. A rolling assembly for single-pass rolling of the elongated precursor superconductor includes two rolls, two constraining members, and a fixture for feeding the precursor superconductor and the constraining members between the rolls. In alternate embodiments of the invention, the rolls can have machined regions which will contact only the elongated constraining members and affect the lateral deformation and movement of those members during the rolling process.

The speciality of periodontics in Australia and New Zealand has seen steady growth since 1986, when the Australian and New Zealand Academy of Periodontics (ANZAP) was formed. Very few members of ANZAP have retired in the 16 years since its formation. However, the results of a survey of members revealed that one-third of members plan to retire within the next 10 years, and over 50% of members will have retired within 15 years. The survey also revealed that most members were heavily booked, and nearly half were concerned by their level of busyness. A total of 22 members are currently seeking to employ a periodontist in their practice, and yet only three students will complete the MDSc program in periodontics in Australia at the end of this year. This paper presents the results of the ANZAP survey of members and addresses issues affecting the training of periodontists in Australia and New Zealand.

Ethical dilemmas are inherently ambiguous, complex, and ill-defined. Additionally, these dilemmas involve multiple stakeholders. These characteristics may induce political behavior as a resolution tactic. Thus, the goal of the present effort was to investigate perspectives on politics among researchers in an ethical decision-making context. A qualitative analysis of interviews with university faculty members revealed that faculty members' perspectives on political behavior in an ethical decision-making context fall into a number of categories, including positive, negative, and realistic views of political activity. The implications of these varying perspectives on ethical decision making are discussed.

We describe a five generation family with dominantly inherited lymphedema, but no distichiasis, in which 3/3 affected offspring in the fifth generation have died of fetal hydrops and related birth defects. Mutational analysis disclosed a novel mutation in FOXC2 (R121C) in affected members. We searched for possible genetic influences on the greater severity of lymphedema (hydrops) in the fifth generation. Karyotypes disclosed an extra band in Xp in one affected fetus but this was also found in the mother. Copy number variation (CNV) studies on four members of the pedigree (mother of the three severely affected fetuses/infants; one severely affected; a full, and a half, unaffected sibs) did not detect the source of the Xp band or a possible influence on the severe phenotype. However, use of SNP arrays did allow identification of the portion of the maternal proximal Xp shared by a hydrops-affected daughter and son which was not shared by an unaffected daughter from the same sibship.

To evaluate the recurrence risk of autism spectrum disorders (ASD) in younger siblings of affected children and determine how it is modified by race/ethnicity and sex. Medical records of children born in a large health maintenance organization (Kaiser Permanent Southern California) hospitals from January 1, 2001, through December 31, 2010, and who remained in our system until 2 to 11 years of age were used to assess the risk of recurrence of ASD in younger siblings. Children born at <28 or >42 weeks gestation, multiple births, or those who were not active members for ≥3 months were excluded. ASD diagnosis was ascertained from DSM-IV codes, and the magnitude of the association was estimated using adjusted relative risks (aRRs). Among eligible younger siblings, 592 (1.11%) had the diagnosis of ASD. The ASD rates were 11.30% and 0.92% for younger siblings of older affected and unaffected siblings, respectively (aRR: 14.27; 95% confidence interval, 11.41-17.83). This association remained after adjusting for potential confounding factors. Race/ethnicity- and gestational age-specific analyses revealed a positive association of similar magnitude across groups. Risk remained higher in younger boys than girls regardless of the sex of affected older siblings. The findings of this study suggest that the risk of ASD in younger siblings is higher if the older sibling has ASD. The risk of ASD in younger siblings of older affected siblings was comparable across gestational age at birth and child's race/ethnicity groups. However, risk remains higher for boys. This study contributes to a better understanding of the influence of race/ethnicity, sex, and gestational age at birth in identifying children at higher risk of ASD.

Patient's lung cancer diagnosis as a cue for relatives' smoking cessation: evaluating the constructs of the teachable moment.

To understand whether patient-reported experiences with lung cancer may create teachable moments (TM) for their relatives as evidenced by shifts in their risk perceptions, affective response, and self-image and in turn, motivation to quit smoking. Patients at a comprehensive cancer center (n = 152) completed a survey within 6 months of lung cancer diagnosis to assess their cancer-related symptoms and openness and enumerated relatives who were smokers. Relative smokers (n = 218) then completed a survey assessing their risk perceptions, affective response, and self-image as a smoker related to the patient's diagnosis (TM mechanisms), and their motivation to quit smoking. Cross-sectional mediation and moderation analyses were conducted to explore the links between patient-reported experiences, and relatives' TM mechanisms, and motivation to quit smoking. Relative-reported affect was a significant mediator of the association between patient-reported symptoms and relative smoker's desire to quit. Relatives' self-image was a significant moderator of the association between patient-reported symptoms and relative smoker's desire to quit, such that patients' reported symptoms were associated with relatives' desire to quit only when the relative smoker reported a generally positive self-image as a smoker. No evidence was found for moderated mediation. However, the link between symptoms and negative affect was moderated by perceptions of risk. Whether smokers experience a family member's lung cancer as a TM is influenced by multiple interrelated cognitive and affective factors that warrant further exploration. Clearer understanding of these factors could inform how to re-invigorate and sustain this motivation to promote concrete actions toward smoking cessation. Copyright © 2015 John Wiley & Sons, Ltd.

Exoplanet orbital eccentricity: multiplicity relation and the Solar System.

PubMed

Limbach, Mary Anne; Turner, Edwin L

2015-01-06

The known population of exoplanets exhibits a much wider range of orbital eccentricities than Solar System planets and has a much higher average eccentricity. These facts have been widely interpreted to indicate that the Solar System is an atypical member of the overall population of planetary systems. We report here on a strong anticorrelation of orbital eccentricity with multiplicity (number of planets in the system) among cataloged radial velocity (RV) systems. The mean, median, and rough distribution of eccentricities of Solar System planets fits an extrapolation of this anticorrelation to the eight-planet case rather precisely despite the fact that no more than two Solar System planets would be detectable with RV data comparable to that in the exoplanet sample. Moreover, even if regarded as a single or double planetary system, the Solar System lies in a reasonably heavily populated region of eccentricity-multiplicity space. Thus, the Solar System is not anomalous among known exoplanetary systems with respect to eccentricities when its multiplicity is taken into account. Specifically, as the multiplicity of a system increases, the eccentricity decreases roughly as a power law of index -1.20. A simple and plausible but ad hoc and model-dependent interpretation of this relationship implies that ∼ 80% of the one-planet and 25% of the two-planet systems in our sample have additional, as yet undiscovered, members but that systems of higher observed multiplicity are largely complete (i.e., relatively rarely contain additional undiscovered planets). If low eccentricities indeed favor high multiplicities, habitability may be more common in systems with a larger number of planets.

Honor among thieves: The interaction of team and member deviance on trust in the team.

PubMed

Schabram, Kira; Robinson, Sandra L; Cruz, Kevin S

2018-05-03

In this article, we examine member trust in deviant teams. We contend that a member's trust in his or her deviant team depends on the member's own deviant actions; although all members will judge the actions of their deviant teams as rational evidence that they should not be trusted, deviant members, but not honest members, can hold on to trust in their teams because of a sense of connection to the team. We tested our predictions in a field study of 562 members across 111 teams and 24 organizations as well as in an experiment of 178 participants in deviant and non-deviant teams. Both studies show that honest members experience a greater decline in trust as team deviance goes up. Moreover, our experiment finds that deviant members have as much trust in their deviant teams as honest members do in honest teams, but only in teams with coordinated rather than independent acts of deviance, in which deviant members engage in a variety of ongoing dynamics foundational to a sense of connection and affective-based trust.

[Dynamic mutations--a newly detected category of mutations which is the basis for certain neurologic diseases].

PubMed

Mardesić, D

1995-01-01

This review offers some basic information on the discovery of a new type of mutations being the cause of some significant neurologic diseases: myotonic dystrophy, Huntington's disease, spinocerebellar ataxia type 1, spinobulbar pallido-louysian muscular atrophy, fragile X syndrome and some other, up to a total of ten entities. The basis of the so-called dynamic mutations is an abnormal multiplication of a trinucleotide producing sequences of several hundreds or even thousands of identical copies in the respective gene. The result is designated as expanded or amplified trinucleotide (or triplet) repeat. These sequences are not stable, but increase (or exceptionally decrease) in length during cell multiplication in successive generations. They segregate within families with the affected members, demonstrating a significant correlation between the length of the repeat sequence, the severity of the pathologic phenotype and an inverse correlation with the age at the clinical manifestation of the disease. Thus, at least, a formal explanation for the anticipation phenomenon of the age at which the disease is manifested within a family is offered. The importance of the discovery of dynamic mutations lies in the possibility for more precise and reliable genetic counselling. The discovery has opened a lot of new questions giving a new impetus for intensive research.

NSP-CAS Protein Complexes: Emerging Signaling Modules in Cancer.

PubMed

Wallez, Yann; Mace, Peter D; Pasquale, Elena B; Riedl, Stefan J

2012-05-01

The CAS (CRK-associated substrate) family of adaptor proteins comprises 4 members, which share a conserved modular domain structure that enables multiple protein-protein interactions, leading to the assembly of intracellular signaling platforms. Besides their physiological role in signal transduction downstream of a variety of cell surface receptors, CAS proteins are also critical for oncogenic transformation and cancer cell malignancy through associations with a variety of regulatory proteins and downstream effectors. Among the regulatory partners, the 3 recently identified adaptor proteins constituting the NSP (novel SH2-containing protein) family avidly bind to the conserved carboxy-terminal focal adhesion-targeting (FAT) domain of CAS proteins. NSP proteins use an anomalous nucleotide exchange factor domain that lacks catalytic activity to form NSP-CAS signaling modules. Additionally, the NSP SH2 domain can link NSP-CAS signaling assemblies to tyrosine-phosphorylated cell surface receptors. NSP proteins can potentiate CAS function by affecting key CAS attributes such as expression levels, phosphorylation state, and subcellular localization, leading to effects on cell adhesion, migration, and invasion as well as cell growth. The consequences of these activities are well exemplified by the role that members of both families play in promoting breast cancer cell invasiveness and resistance to antiestrogens. In this review, we discuss the intriguing interplay between the NSP and CAS families, with a particular focus on cancer signaling networks.

The aim of this study was to explore cultural differences in causal attributions and beliefs about heritability of major depressive disorder (MDD). Face-to-face interviews with Anglo-Celtic- and Chinese-Australians community members with a family history of MDD were conducted and subjected to a rigorous qualitative analysis, using the computer software NVivo. Sixteen Anglo-Celtic-Australians and 16 Chinese-Australians were interviewed. Both groups believed that a combination of genetic and environmental factors contributed to MDD, that stress was an important cause of MDD, and that coping factors were significant moderators of the impact of stress on MDD. Both cultural groups believed that the causes of MDD affecting multiple family members included a shared family environment and a "contagion effect", in addition to genetics. Unique to the Chinese-Australian group was the beliefs that parental pressures to exceed academically contributed to MDD; this cultural group also reported beliefs that depression was due to God's will or alternatively fate, which in turn was related to attributions to feng shui and auspicious dates. This study documented key culture-specific differences in beliefs about causes and inheritance of MDD; such differences have major implications for clinician-patient communication about genetic risk associated with having a family history of MDD.

Characterization of a purine permease family gene OsPUP7 involved in growth and development control in rice.

PubMed

Qi, Zhuyun; Xiong, Lizhong

2013-11-01

In this study, PUP-type cytokinin transporter genes were identified in rice (Oryza sativa L.). The Oryza sativa purine permease (OsPUP) family has 12 members that show similar predicted protein sequences with AtPUPs. To reveal the functions of OsPUP genes, we searched the T-DNA mutant library of rice and found one mutant for the member OsPUP7. The T-DNA insertion caused a new transcript that encodes a protein with 26 amino acids different from the native OsPUP7 at the C-terminus. The mutant showed multiple phenotypic changes including increased plant height, big seeds, and delayed flowering. The mutant also showed increased sensitivity to drought and salt stresses and treatments with kinetin and abscisic acid. OsPUP7 is expressed mainly in the vascular bundle, pistil, and stamens. The measurement of cytokinins (CKs) showed that CK content in the mutant spikelets accumulated higher than that in the wild type. Moreover, uptake experiment in the yeast fcy2 mutant suggested that OsPUP7 has the ability to transport caffeine, a CK derivative. Our results indicate that the PUP transport system also exists in rice, and OsPUP7 has an important role in the transport of CK, thus affecting developmental process and stress responses. © 2013 Institute of Botany, Chinese Academy of Sciences.

Improving community members' knowledge of obstetric danger signs is one strategy for increasing the use of skilled care during pregnancy and the puerperium. This study explored knowledge of obstetric danger signs among a range of community members, examined the sources of their information, and the perceived factors that affect health seeking behaviour in rural northern Ghana. We conducted 72 in-depth interviews and 18 focus groups with community members. All interactions were audio taped, transcribed verbatim and analysed using NVivo 9.0. Community members demonstrated knowledge of a wide range of obstetric danger signs, including excessive bleeding, stomach aches, waist pains, vomiting and fever. Pregnant women learn about danger signs from a range of providers, and regular contact with formal providers typically coincided with increased knowledge of danger signs. Traditional remedies for problems in obstetrics are plentiful and cultural beliefs often restrict the use of allopathic medicine. Increasing knowledge of obstetric danger signs is necessary but not sufficient to overcome cultural preferences for traditional treatments for pregnancy danger signs.

We used an unbiased genome-wide approach to identify exonic variants segregating with diabetes in a multigenerational Finnish family. At least eight members of this family presented with diabetes with age of diagnosis ranging from 18 to 51 years and a pattern suggesting autosomal dominant inheritance. We sequenced the exomes of four affected members of this family and performed follow-up genotyping of additional affected and unaffected family members. We uncovered a novel nonsynonymous variant (p.Trp314Arg) in the Wolfram syndrome 1 (WFS1) gene that segregates completely with the diabetic phenotype. Multipoint parametric linkage analysis with 13 members of this family identified a single linkage signal with maximum logarithm of odds score 3.01 at 4p16.2-p16.1, corresponding to a region harboring the WFS1 locus. Functional studies demonstrate a role for this variant in endoplasmic reticulum stress, which is consistent with the β-cell failure phenotype seen in mutation carriers. This represents the first compelling report of a mutation in WFS1 associated with dominantly inherited nonsyndromic adult-onset diabetes. PMID:23903355

Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF.

The Trauma Time-Out: Evaluating the Effectiveness of Protocol-Based Information Dissemination in the Traumatically Injured Patient.

PubMed

Nolan, Heather R; Fitzgerald, Michael; Howard, Brett; Jarrard, Joey; Vaughn, Danny

Procedural time-outs are widely accepted safety standards that are protocolized in nearly all hospital systems. The trauma time-out, however, has been largely unstudied in the existing literature and does not have a standard protocol outlined by any of the major trauma surgery organizations. The goal of this study was to evaluate our institution's use of the trauma time-out and assess how trauma team members viewed its effectiveness. A multiple-answer survey was sent to trauma team members at a Level I trauma center. Questions included items directed at background, experience, opinions, and write-in responses. Most responders were experienced trauma team members who regularly participated in trauma codes. All respondents noted the total time required to complete the time-out was less than 5 min, with the majority saying it took less than 1 min. Seventy-five percent agreed that trauma time-outs should continue, with 92% noting that it improved understanding of patient presentation and prehospital evaluation. Seventy-seven percent said it improved understanding of other team member's roles, and 75% stated it improved patient care. Subgroups of physicians and nurses were statistically similar; yet, physicians did note that it improved their understanding of the team member's function more frequently than nurses. The trauma time-out can be an excellent tool to improve patient care and team understanding of the incoming trauma patient. Although used widely at multiple levels of trauma institutions, development of a documented protocol can be the next step in creating a unified safety standard.

This article describes the care processes for a 64-year-old man with newly diagnosed advanced non–small-cell lung cancer who was enrolled in a first-line clinical trial of a new immunotherapy regimen. The case highlights the concept of multiteam systems in cancer clinical research and clinical care. Because clinical research represents a highly dynamic entity—with studies frequently opening, closing, and undergoing modifications—concerted efforts of multiple teams are needed to respond to these changes while continuing to provide consistent, high-level care and timely, accurate clinical data. The case illustrates typical challenges of multiteam care processes. Compared with clinical tasks that are routinely performed by single teams, multiple-team care greatly increases the demands for communication, collaboration, cohesion, and coordination among team members. As the case illustrates, the described research team and clinical team are separated, resulting in suboptimal function. Individual team members interact predominantly with members of their own team. A considerable number of team members lack regular interaction with anyone outside their team. Accompanying this separation, the teams enact rivalries that impede collaboration. The teams have misaligned goals and competing priorities that create competition. Collective identity and cohesion across the two teams are low. Research team and clinical team members have limited knowledge of the roles and work of individuals outside their team. Recommendations to increase trust and collaboration are provided. Clinical providers and researchers may incorporate these themes into development and evaluation of multiteam systems, multidisciplinary teams, and cross-functional teams within their own institutions.

2015-01-01

The organic-rich upper shale member of the upper Devonian–lower Mississippian Bakken Formation (Williston Basin, North Dakota, USA) has undergone significant diagenetic alteration, irrespective of catagenesis related to hydrocarbon generation. Alteration includes precipitation of numerous cements, replacement of both detrital and authigenic minerals, multiple episodes of fracturing, and compaction. Quartz authigenesis occurred throughout much of the member, and is represented by multiple generations of microcrystalline quartz. Chalcedonic quartz fills radiolarian microfossils and is present in the matrix. Sulfide minerals include pyrite and sphalerite. Carbonate diagenesis is volumetrically minor and includes thin dolomite overgrowths and calcite cement. At least two generations of fractures are observed. Based on the authigenic minerals and their relative timing of formation, the evolution of pore waters can be postulated. Dolomite and calcite resulted from early postdepositional aerobic oxidation of some of the abundant organic material in the formation. Following aerobic oxidation, conditions became anoxic and sulfide minerals precipitated. Transformation of the originally opaline tests of radiolaria resulted in precipitation of quartz, and quartz authigenesis is most common in more distal parts of the depositional basin where radiolaria were abundant. Because quartz authigenesis is related to the distribution of radiolaria, there is a link between diagenesis and depositional environment. Furthermore, much of the diagenesis in the upper shale member preceded hydrocarbon generation, so early postdepositional processes were responsible for occlusion of significant original porosity in the member. Thus, diagenetic mineral precipitation was at least partly responsible for the limited ability of these mudstones to provide porosity for storage of hydrocarbons.

The purpose of this study was to determine quality of life (QOL) related factors in Alcoholics Anonymous (AA) members based on PRECEDE Model. A cross sectional survey was conducted with participants (N =203) from AA meeting in 11 alcohol counsel centers all over South Korea. Data were collected using a specially designed questionnaire based on the PRECEDE model and including QOL, epidemiological factors (including depression and perceived health status), behavioral factors (continuous abstinence and physical health status and practice), predisposing factors (abstinence self-efficacy and self-esteem), reinforcing factors (social capital and family functioning), and enabling factors. Data were analyzed using t-test, one way ANOVA, Tukey HSD test and hierarchical multiple regression analysis with SPSS (ver. 21.0). Of the educational diagnostic variables, self-esteem (β=.23), family functioning (β=.12), abstinence self-efficacy (β=.12) and social capital (β=.11) were strong influential factors in AA members' QOL. In addition, epidemiological diagnostic variables such as depression (β=-.44) and perceived health status (β=.35) were the main factors in QOL. Also, physical health status and practice (β=.106), one of behavioral diagnostic variables was a beneficial factor in QOL. Hierarchical multiple regression analysis showed the determinant variables accounted for 44.0% of the variation in QOL (F=25.76, p<.001). The finding of the study can be used as a framework for planning interventions in order to promote the quality of life of AA members. It is necessary to develop nursing intervention strategies for strengthening educational and epidemiological diagnostic variables in order to improve AA members' QOL.

Unintentional injury remains the leading cause of morbidity and mortality among children worldwide. The aims of this study were to assess a baseline level of first aid knowledge and overall attitudes regarding first aid among staff members in Shanghai preschools. A cross-sectional study was carried out among the staff members at selected preschools. A stratified random sampling method was first used to identify suitable subjects. Data were obtained using a multiple-choice questionnaire. A standardized collection of demographics was performed and participants were given the aforementioned questionnaire to indicate knowledge of and attitudes toward first aid. 1067 subjects completed the questionnaire. None of the surveyed employees answered all questions correctly; only 39 individuals (3.7%) achieved passing scores. The relative number of correct answers to specific questions ranged from 16.5% to 90.2%. In particular, subjects lacked knowledge regarding first aid for convulsive seizures (only 16.5% answered correctly), chemical injuries to the eye (23%), inhaled poison (27.6%), and choking and coughing (30.1%). A multiple linear regression analysis showed scores were significantly higher among staff members with more education, those who had received first aid training before or were already healthcare providers, younger employees, and staff members from rural districts. Most employees agreed that giving first aid was helpful; the vast majority felt that it was important and useful for them to learn pediatric first aid. The level of first-aid knowledge among preschool staffs in Shanghai was low. There is an urgent need to educate staff members regarding first aid practices and the various risk factors relating to specific injuries.

Multiple insurance funds serving different population groups may compromise equity due to differential revenue raising capacity and an unequal distribution of high risk members among the funds. This occurs when the funds exist without mechanisms in place to promote income and risk cross-subsidisation across the funds. This paper analyses whether the risk distribution varies across the Community Health Fund (CHF) and National Health Insurance Fund (NHIF) in two districts in Tanzania. Specifically we aim to 1) identify risk factors associated with increased utilisation of health services and 2) compare the distribution of identified risk factors among the CHF, NHIF and non-member households. Data was collected from a survey of 695 households. A multivariate logisitic regression model was used to identify risk factors for increased health care utilisation. Chi-square tests were performed to test whether the distribution of identified risk factors varied across the CHF, NHIF and non-member households. There was a higher concentration of identified risk factors among CHF households compared to those of the NHIF. Non-member households have a similar wealth status to CHF households, but a lower concentration of identified risk factors. Mechanisms for broader risk spreading and cross-subsidisation across the funds are necessary for the promotion of equity. These include risk equalisation to adjust for differential risk distribution and revenue raising capacity of the funds. Expansion of CHF coverage is equally important, by addressing non-financial barriers to CHF enrolment to encourage wealthy non-members to join, as well as subsidised membership for the poorest.

Saliendo Adelante: Stressors and Coping Strategies Among Immigrant Latino Men Who Have Sex With Men in a Nontraditional Settlement State.

Immigrant Latino men who have sex with men (MSM) are marginalized along multiple dimensions (e.g., ethnicity, sexual orientation, language use), which can negatively affect their health and well-being. As little is known about how this subgroup experiences the stress of marginalization and how, in turn, they cope with such stress, this study investigated stressors and coping strategies to better understand the factors shaping Latino MSM health. Assisted by a community advisory committee, we conducted in-depth interviews with 15 foreign-born Latino MSM in a nontraditional settlement state. Drawing on grounded theory methods, we analyzed transcripts iteratively to identify processes and characterize themes. Results were confirmed in member check interviews (n = 4) and findings were further contextualized through key informant interviews (n = 3). Participants reported ubiquitous, concurrent stressors due to being an immigrant, being a sexual minority, and being working poor. In particular, homophobia within families and local Latino communities was seen as pervasive. Some participants faced additional stressors due to being undocumented and not being Mexican. Participants drew on four types of coping strategies, with no dominant coping response: passive coping (i.e., not reacting to stressors); attempting to change stressors; seeking social support; and seeking distractions. Family ties, especially with mothers, provided key emotional support but could also generate stress related to participants' sexuality. This study lays a foundation for future work and is particularly relevant for Latino MSM in nontraditional settlement states. Findings may inform future interventions to reduce stressors and increase resiliency, which can positively affect multiple health outcomes. © The Author(s) 2016.

Families have an important role supporting a family member with problematic substance use (PSU), although this can often be challenging and confronting. Previous research has identified high rates of family aggression and violence within the context of PSU, although few studies have examined this issue from the perspective of affected family members (AFMs) supporting a member with PSU. The aims of the current study were to understand AFMs' experience of aggression and violence while supporting a member with PSU, and to explicate the strategies they used to prevent and cope with this behaviour. Semi-structured, audio-recorded qualitative interviews were conducted with 31 AFMs from the state of Victoria in Australia. Interpretative Phenomenological Analysis was used to guide data collection and analysis. Almost 70% of participants experienced PSU-related family aggression and/or violence. Two main themes and related sub-themes were abstracted from the data capturing their experiences of this behaviour and the strategies they used to try to prevent and cope in this situation. Aggression and/or violence were variable, changeable and unpredictable; and aggression and/or violence altering social interactions and family dynamics. As a consequence, it was upsetting, stressful and emotionally exhausting to AFMs. In response to this experience, and largely through trial and error, they used several direct strategies to try to prevent and cope with the behaviour; however, most continued to struggle in these circumstances. They also highlighted additional indirect measures, which, if adopted, would enhance their existing direct strategies. More effective primary, secondary and tertiary preventive measures are needed to address family aggression and violence within the context of PSU. More support is needed for family members affected by PSU to enable them to 'stand up to,' to prevent and cope effectively with this behaviour, and to increase their help-seeking and access to specialist services and support groups. More appropriate policies and social services are needed to meet the needs of AFMs.

Chronic obstructive pulmonary disease (COPD) is a complex and heritable disease, associated with multiple genetic variants. Specific familial types of COPD may be explained by rare variants, which have not been widely studied. We aimed to discover rare genetic variants underlying COPD through a genome-wide linkage scan. Affected-only analysis was performed using the 6K Illumina Linkage IV Panel in 142 cases clustered in 27 families from a genetic isolate, the Erasmus Rucphen Family (ERF) study. Potential causal variants were identified by searching for shared rare variants in the exome-sequence data of the affected members of the families contributing most to the linkage peak. The identified rare variants were then tested for association with COPD in a large meta-analysis of several cohorts. Significant evidence for linkage was observed on chromosomes 15q14-15q25 [logarithm of the odds (LOD) score = 5.52], 11p15.4-11q14.1 (LOD = 3.71) and 5q14.3-5q33.2 (LOD = 3.49). In the chromosome 15 peak, that harbors the known COPD locus for nicotinic receptors, and in the chromosome 5 peak we could not identify shared variants. In the chromosome 11 locus, we identified four rare (minor allele frequency (MAF) <0.02), predicted pathogenic, missense variants. These were shared among the affected family members. The identified variants localize to genes including neuroblast differentiation-associated protein ( AHNAK ), previously associated with blood biomarkers in COPD, phospholipase C Beta 3 ( PLCB3 ), shown to increase airway hyper-responsiveness, solute carrier family 22-A11 ( SLC22A11 ), involved in amino acid metabolism and ion transport, and metallothionein-like protein 5 ( MTL5 ), involved in nicotinate and nicotinamide metabolism. Association of SLC22A11 and MTL5 variants were confirmed in the meta-analysis of 9,888 cases and 27,060 controls. In conclusion, we have identified novel rare variants in plausible genes related to COPD. Further studies utilizing large sample whole-genome sequencing should further confirm the associations at chromosome 11 and investigate the chromosome 15 and 5 linked regions.

Spline screw multiple rotations mechanism

Vranish, John M. (Inventor)

1993-01-01

A system for coupling two bodies together and for transmitting torque from one body to another with mechanical timing and sequencing is reported. The mechanical timing and sequencing is handled so that the following criteria are met: (1) the bodies are handled in a safe manner and nothing floats loose in space, (2) electrical connectors are engaged as long as possible so that the internal processes can be monitored throughout by sensors, and (3) electrical and mechanical power and signals are coupled. The first body has a splined driver for providing the input torque. The second body has a threaded drive member capable of rotation and limited translation. The embedded drive member will mate with and fasten to the splined driver. The second body has an embedded bevel gear member capable of rotation and limited translation. This bevel gear member is coaxial with the threaded drive member. A compression spring provides a preload on the rotating threaded member, and a thrust bearing is used for limiting the translation of the bevel gear member so that when the bevel gear member reaches the upward limit of its translation the two bodies are fully coupled and the bevel gear member then rotates due to the input torque transmitted from the splined driver through the threaded drive member to the bevel gear member. An output bevel gear with an attached output drive shaft is embedded in the second body and meshes with the threaded rotating bevel gear member to transmit the input torque to the output drive shaft.

This study aims to examine the effect of the death of a family member or friend on psychological well-being, specifically the moderating effects of first-time volunteering and social network. With the sample of 354 volunteers from the Experience Corps® (EC) programs, Analysis of covariance (ANCOVA) estimated the differences in psychological well-being. Among volunteers who had experienced the death of a family member or friend, new volunteers showed significant improvement in positive affect compared to experienced volunteers. EC members gained additional social contacts through volunteering. Formal volunteering has a salutatory effect on older adults' health after the loss of family members.

From a basis in social exchange theory, the authors investigated whether, and how, negative feedback-seeking behavior and a team empowerment climate affect the relationship between leader-member exchange (LMX) and member performance. Results showed that subordinates' negative feedback-seeking behavior mediated the relationship between LMX and both objective and subjective in-role performance. In addition, the level of a team's empowerment climate was positively related to subordinates' own sense of empowerment, which in turn negatively moderated the effects of LMX on negative feedback-seeking behavior. 2007 APA, all rights reserved

2017-12-01

The International Charter aims at providing a unified system of space data acquisition and delivery to national disaster authorities of countries affected by natural or man-made disasters. Each of the sixteen Member Agencies has committed resources to support the objectives of the Charter and thus helping to mitigate the effects of disasters on human life and property, getting critical information into the hands of the disaster responders so that they can make informed decisions in the wake of a disaster. The Charter Member Agencies work together to provide remotely sensed imagery to any requesting country that is experiencing a natural or man-made disaster. The Space Agencies contribute priority satellite taskings, archive retrievals, and map production, as well as imagery of the affected areas. The imagery is provided at no cost to the affected country and is made available for the immediate response phase of the disaster. The Charter also has agreements with Sentinel Asia to submit activation requests on behalf of its 30+ member countries and the United Nations Office of Outer Space Affairs (UN OOSA) and United Nations Institute for Training and Research (UNITAR)/ United Nations Operational Satellite Applications Programme (UNOSAT) to submit activations on behalf of United Nations relief agencies such as UNICEF and UNOCHA. To further expand accessibility to the Charter Member Agency resources, the Charter has implemented the Universal Access initiative, which allows any country's disaster management authority to submit an application, attend a brief training session, and after successful completion, become an Authorized User able to submit activation requests without assistance from Member Agencies. The data provided by the Charter is used for many purposes including damage assessments, reference maps, evacuation route planning, search and rescue operations, decision maker briefings, scientific evaluations, and other response activities.

Generalized topology for resonators having N commensurate harmonics

Danzi, Francesco; Gibert, James M.; Frulla, Giacomo; Cestino, Enrico

2018-04-01

Despite the ubiquity of both linear and nonlinear multimember resonators in MEMS and kinetic energy harvesting devices very few research efforts examine the orientation of members in the resonator on its dynamic behavior. Previous efforts to design this type of resonator constrains the members to have relative orientations that are 0○ or 90○ to each other, i.e., the elements are connected inline with adjoining members or are perpendicular to adjoining members. The work expands upon the existing body of research by considering the effect of the relative orientation between members on the dynamic behavior of the system. In this manuscript, we derive a generalized reduced-order model for the design of a multi-member planar resonator that has integer multiple modal frequencies. The model is based on a Rayleigh Ritz approximation where the number of degrees of freedom equals the number of structural members in the resonator. The analysis allows the generation of design curves, representing all the possible solutions for modal frequencies that are commensurate. The generalized model, valid for an N-DOF structure, is then restricted for a 2- and 3-DOF system/member resonator, where the linear dynamic behavior of the resonator is investigated in depth. Furthermore, this analysis demonstrates a rule of thumb; relaxing restrictions on the relative orientation of members in a planar structure, allows the structure to exhibit exactly N commensurable frequencies if it contains N members.

Microtubule (MT)-based motor proteins, kinesins and dyneins, play important roles in multiple cellular processes including cell division. In this study, we describe the generation and use of an Escherichia coli RNase III-prepared human kinesin/dynein esiRNA library to systematically analyze the functions of all human kinesin/dynein MT motor proteins. Our results indicate that at least 12 kinesins are involved in mitosis and cytokinesis. Eg5 (a member of the kinesin-5 family), Kif2A (a member of the kinesin-13 family), and KifC1 (a member of the kinesin-14 family) are crucial for spindle formation; KifC1, MCAK (a member of the kinesin-13 family), CENP-E (a member of the kinesin-7 family), Kif14 (a member of the kinesin-3 family), Kif18 (a member of the kinesin-8 family), and Kid (a member of the kinesin-10 family) are required for chromosome congression and alignment; Kif4A and Kif4B (members of the kinesin-4 family) have roles in anaphase spindle dynamics; and Kif4A, Kif4B, MKLP1, and MKLP2 (members of the kinesin-6 family) are essential for cytokinesis. Using immunofluorescence analysis, time-lapse microscopy, and rescue experiments, we investigate the roles of these 12 kinesins in detail. PMID:15843429

Right-wing authoritarianism and stereotype-driven expectations interact in shaping intergroup trust in one-shot vs multiple-round social interactions

Trust towards unrelated individuals is often conditioned by information about previous social interactions that can be derived from either personal or vicarious experience (e.g., reputation). Intergroup stereotypes can be operationalized as expectations about other groups’ traits/attitudes/behaviors that heavily influence our behavioral predictions when interacting with them. In this study we investigated the role of perceived social dimensions of the Stereotype Content Model (SCM)–Warmth (W) and Competence (C)—in affecting trusting behavior towards different European national group members during the Trust Game. Given the well-known role of ideological attitudes in regulating stereotypes, we also measured individual differences in right-wing authoritarianism (RWA). In Experiment 1, we designed an online survey to study one-shot intergroup trust decisions by employing putative members of the European Union states which were also rated along SCM dimensions. We found that low-RWA participants’ trusting behavior was driven by perceived warmth (i.e., the dimension signaling the benevolence of social intentions) when interacting with low-C groups. In Experiment 2, we investigated the dynamics of trust in a multiple-round version of the European Trust Game. We found that in low-RWA participants trusting behavior decreased over time when interacting with high-W groups (i.e., expected to reciprocate trust), but did not change when interacting with low-W groups (i.e., expected not to reciprocate trust). Moreover, we found that high-RWA participants’ trusting behavior decreased when facing low-W groups but not high-W ones. This suggests that low-RWA individuals employ reputational priors but are also permeable to external evidence when learning about others’ trustworthiness. In contrast, high-RWA individuals kept relying on stereotypes despite contextual information. These results confirm the pivotal role played by reputational priors triggered by perceived warmth in shaping social interactions. PMID:29284019

Work-family conflict (WFC) involves discord that arises when the demands of work interfere with the demands of family or home life. Long work hours, minimal control over work schedules, and time spent away from home are antecedents to WFC. To date, few authors have examined work-family conflict within the athletic training profession. To investigate the occurrence of WFC in certified athletic trainers (ATs) and to identify roots and factors leading to quality-of-life issues for ATs working in the National Collegiate Athletic Association Division I-A setting. Survey questionnaire and follow-up, in-depth, in-person interviews. Division I-A universities sponsoring football. A total of 587 ATs (324 men, 263 women) responded to the questionnaire. Twelve ATs (6 men, 6 women) participated in the qualitative portion: 2 head ATs, 4 assistant ATs, 4 graduate assistant ATs, and 2 AT program directors. Multiple regression analysis was performed to determine whether workload and travel predicted levels of WFC. Analyses of variance were calculated to investigate differences among the factors of sex, marital status, and family status. Interviews were transcribed verbatim and then analyzed using computer software as well as member checks and peer debriefing. The triangulation of the data collection and multiple sources of qualitative analysis were utilized to limit potential researcher prejudices. Regression analyses revealed that long work hours and travel directly contributed to WFC. In addition to long hours and travel, inflexible work schedules and staffing patterns were discussed by the interview participants as antecedents to WFC. Regardless of sex (P = .142), marital status (P = .687), family status (P = .055), or age of children (P = .633), WFC affected Division I-A ATs. No matter their marital or family status, ATs employed at the Division I-A level experienced difficulties balancing their work and home lives. Sources of conflict primarily stemmed from the consuming nature of the profession, travel, inflexible work schedules, and lack of full-time staff members.

NM23 proteins: innocent bystanders or local energy boosters for CFTR?

PubMed

Muimo, Richmond; Alothaid, Hani Mm; Mehta, Anil

2018-03-01

NM23 proteins NDPK-A and -B bind to the cystic fibrosis (CF) protein CFTR in different ways from kinases such as PKA, CK2 and AMPK or linkers to cell calcium such as calmodulin and annexins. NDPK-A (not -B) interacts with CFTR through reciprocal AMPK binding/control, whereas NDPK-B (not -A) binds directly to CFTR. NDPK-B can activate G proteins without ligand-receptor coupling, so perhaps NDPK-B's binding influences energy supply local to a nucleotide-binding site (NBD1) needed for CFTR to function. Curiously, CFTR (ABC-C7) is a member of the ATP-binding cassette (ABC) protein family that does not obey 'clan rules'; CFTR channels anions and is not a pump, regulates disparate processes, is itself regulated by multiple means and is so pleiotropic that it acts as a hub that orchestrates calcium signaling through its consorts such as calmodulin/annexins. Furthermore, its multiple partners make CFTR dance to different tunes in different cellular and subcellular locations as it recycles from the plasma membrane to endosomes. CFTR function in airway apical membranes is inhibited by smoking which has been dubbed 'acquired CF'. CFTR alone among family members possesses a trap for other proteins that it unfurls as a 'fish-net' and which bears consensus phosphorylation sites for many protein kinases, with PKA being the most canonical. Recently, the site of CFTR's commonest mutation has been proposed as a knock-in mutant that alters allosteric control of kinase CK2 by log orders of activity towards calmodulin and other substrates after CFTR fragmentation. This link from CK2 to calmodulin that binds the R region invokes molecular paths that control lumen formation, which is incomplete in the tracheas of some CF-affected babies. Thus, we are poised to understand the many roles of NDPK-A and -B in CFTR function and, especially lumen formation, which is defective in the gut and lungs of many CF babies.

The goal of this study was to examine the factors that affect career satisfaction in orthopaedic traumatologists. We hypothesize that the level of stress and career satisfaction in orthopaedic traumatology would be affected by increased number of call nights and work hours. A 30-question survey was emailed to members of the OTA. The survey evaluated 5 critical areas: training/experience, practice characteristics, demands, stress management strategies, and satisfaction. After approval by the OTA research committee, all active and associate US members of the OTA were contacted. The survey was open to the OTA members from July through November of 2012. Of 1031 members of the OTA, 263 members responded for an overall response rate of 25.5%. Most respondents were fellowship-trained (218, 82.9%) and predominantly young (<5 years in practice, 34.4%) or established surgeons (>15 years in practice, 28.5%). Most surgeons were married (229, 87.1%) and have not been divorced (226, 85.9%). Career satisfaction was statistically improved by belonging to larger practice (P = 0.016), decreased by work for more hours per week (P = 0.001), and improved by taking more call (P = 0.014). Career satisfaction among orthopaedic trauma surgeons was extremely high. Our results indicate that young surgeons may improve their job satisfaction and potentially prolong their career by limiting the numbers of hours worked, taking a consistent number of calls and joining a larger group.

To analyze the phenotype-genotype correlation of MYH7-V878A mutation. Exonic amplification and high-throughput sequencing of 96-cardiovascular disease-related genes were carried out on probands from 210 pedigrees affected with hypertrophic cardiomyopathy (HCM). For the probands, their family members, and 300 healthy volunteers, the identified MYH7-V878A mutation was verified by Sanger sequencing. Information of the HCM patients and their family members, including clinical data, physical examination, echocardiography (UCG), electrocardiography (ECG), and conserved sequence of the mutation among various species were analyzed. A MYH7-V878A mutation was detected in five HCM pedigrees containing 31 family members. Fourteen members have carried the mutation, among whom 11 were diagnosed with HCM, while 3 did not meet the diagnostic criteria. Some of the fourteen members also carried other mutations. Family members not carrying the mutation had normal UCG and ECG. No MYH7-V878A mutation was found among the 300 healthy volunteers. Analysis of sequence conservation showed that the amino acid is located in highly conserved regions among various species. MYH7-V878A is a hot spot among ethnic Han Chinese with a high penetrance. Functional analysis of the conserved sequences suggested that the mutation may cause significant alteration of the function. MYH7-V878A has a significant value for the early diagnosis of HCM.

The highly stressful conditions of a war zone may exacerbate or trigger a wide variety of symptoms including Obsessive Compulsive Disorder (OCD) once a service member returns home. Service members and new veterans of the Iraq and Afghanistan wars present to treatment with multiple psychosocial concerns and co-morbid psychiatric conditions. Evidence-based treatments including exposure based therapies are commonly recommended for use with returning veterans. Although studies support the efficacy of Exposure Response Prevention (ERP) therapy for treating OCD, eligibility for these studies limits participation to subjects who self-report a well-defined, circumscribed complaint. This approach is not typical of clinic clients who, more often than not, report multiple psychological issues. The following individual case study demonstrates how integrating hypnosis facilitated the cognitive-behavioral ERP therapy and treatment for a patient suffering from OCD.

Sedentary plant-parasitic nematodes engage in complex interactions with their host plants by secreting effector proteins. Some effectors of both root-knot nematodes (Meloidogyne spp.) and cyst nematodes (Heterodera and Globodera spp.) mimic plant ligand proteins. Most prominently, cyst nematodes secrete effectors that mimic plant CLAVATA3/ESR-related (CLE) ligand proteins. However, only cyst nematodes have been shown to secrete such effectors and to utilize CLE ligand mimicry in their interactions with host plants. Here, we document the presence of ligand-like motifs in bona fide root-knot nematode effectors that are most similar to CLE peptides from plants and cyst nematodes. We have identified multiple tandem CLE-like motifs conserved within the previously identified Meloidogyne avirulence protein (MAP) family that are secreted from root-knot nematodes and have been shown to function in planta. By searching all 12 MAP family members from multiple Meloidogyne spp., we identified 43 repetitive CLE-like motifs composing 14 unique variants. At least one CLE-like motif was conserved in each MAP family member. Furthermore, we documented the presence of other conserved sequences that resemble the variable domains described in Heterodera and Globodera CLE effectors. These findings document that root-knot nematodes appear to use CLE ligand mimicry and point toward a common host node targeted by two evolutionarily diverse groups of nematodes. As a consequence, it is likely that CLE signaling pathways are important in other phytonematode pathosystems as well.

Warming and top predator loss drive ecosystem multifunctionality.

Global change affects ecosystem functioning both directly by modifications in physicochemical processes, and indirectly, via changes in biotic metabolism and interactions. Unclear, however, is how multiple anthropogenic drivers affect different components of community structure and the performance of multiple ecosystem functions (ecosystem multifunctionality). We manipulated small natural freshwater ecosystems to investigate how warming and top predator loss affect seven ecosystem functions representing two major dimensions of ecosystem functioning, productivity and metabolism. We investigated their direct and indirect effects on community diversity and standing stock of multitrophic macro and microorganisms. Warming directly increased multifunctional ecosystem productivity and metabolism. In contrast, top predator loss indirectly affected multifunctional ecosystem productivity via changes in the diversity of detritivorous macroinvertebrates, but did not affect ecosystem metabolism. In addition to demonstrating how multiple anthropogenic drivers have different impacts, via different pathways, on ecosystem multifunctionality components, our work should further spur advances in predicting responses of ecosystems to multiple simultaneous environmental changes. © 2017 John Wiley & Sons Ltd/CNRS.

2015-10-01

The flipped classroom approach has garnered significant attention in health professions education, which has resulted in calls for curriculum-wide implementations of the model. However, research to support the development of evidence-based guidelines for large-scale flipped classroom implementations is lacking. This study was designed to examine how students experience the flipped classroom model of learning in multiple courses within a single curriculum, as well as to identify specific elements of flipped learning that students perceive as beneficial or challenging. A qualitative analysis of students' comments (n = 6010) from mid-course and end-of-course evaluations of 10 flipped courses (in 2012-2014) was conducted. Common and recurring themes were identified through systematic iterative coding and sorting using the constant comparison method. Multiple coders, agreement through consensus and member checking were utilised to ensure the trustworthiness of findings. Several themes emerged from the analysis: (i) the perceived advantages of flipped learning coupled with concerns about implementation; (ii) the benefits of pre-class learning and factors that negatively affect these benefits, such as quality and quantity of learning materials, as well as overall increase in workload, especially in the context of multiple concurrent flipped courses; (iii) the role of the instructor in the flipped learning environment, particularly in engaging students in active learning and ensuring instructional alignment, and (iv) the need for assessments that emphasise the application of knowledge and critical thinking skills. Analysis of data from 10 flipped courses provided insight into common patterns of student learning experiences specific to the flipped learning model within a single curriculum. The study points to the challenges associated with scaling the implementation of the flipped classroom across multiple courses. Several core elements critical to the effective design and implementation of the flipped classroom model are identified. © 2015 John Wiley & Sons Ltd.

In this article, Susan Krieger reflects on lessons learned from her classic study of a lesbian community, The Mirror Dance, first published in 1983. Krieger's study was unusual in that it eschewed a traditional social scientist's narrative voice, and instead was written from the point of view of the multiple voices of community members. In this retrospective piece, Krieger again challenges us to think in "multiple voices" about the importance of lesbian communities.

Purpose Screening of mutations in the paired box 3 (PAX3) gene in three generations of a Turkish family with Waardenburg syndrome type 1 (WS1). Methods WS1 was diagnosed in a 13-month-old girl according to the WS Consortium criteria. Detailed family history of the proband revealed eight affected members in three generations. Routine clinical and audiological examination and ophthalmologic evaluation were performed on eight affected and five healthy members of the study family. Dystopia canthorum was detected in all affected patients; however, a brilliant blue iris was present in five patients who also had mild retinal hypopigmentation. Genomic DNA was extracted from the peripheral blood of affected and unaffected individuals in the family as well as 50 unrelated healthy volunteers. All coding exons and adjacent intronic regions of PAX3 were sequenced directly. Results A novel missense heterozygous c.788T>G mutation was identified in eight patients. This nucleotide alteration was not found in unaffected members of the study family or in the 50 unrelated control subjects. The mutation causes V263G amino-acid substitution in the homeodomain of the PAX3 protein, which represents the 45th residue of helix 3. Conclusions We identified a novel missense c.788T>G mutation in PAX3 in a family with Waardenburg syndrome with intrafamilial phenotypic heterogeneity. PMID:23378733

1994-12-01

To diagnose the carriers and noncarriers in a family affected with Norrie disease based on molecular analysis. Family members from three generations, including one affected patient, two obligate carriers, one carrier identified with linkage analysis, one noncarrier identified with linkage analysis, and one female family member with indeterminate carrier status, were examined clinically and electrophysiologically. Linkage analysis had previously failed to determine the carrier status of one female family member in the third generation. Blood samples were screened for mutations in the Norrie disease gene with single-strand conformation polymorphism analysis. The mutation was characterized by dideoxy-termination sequencing. Ophthalmoscopy and electroretinographic examination failed to detect the carrier state. The affected individuals and carriers in this family were found to have a transition from thymidine to cytosine in the first nucleotide of codon 39 of the Norrie disease gene, causing a cysteine-to-arginine mutation. Single-strand conformation polymorphism analysis identified a patient of indeterminate status (by linkage) to be a noncarrier of Norrie disease. Ophthalmoscopy and electroretinography could not identify carriers of this Norrie disease mutation. Single-strand conformation polymorphism analysis was more sensitive and specific than linkage analysis in identifying carriers in this family.

Novel FAM20A mutation causes autosomal recessive amelogenesis imperfecta.

Volodarsky, Michael; Zilberman, Uri; Birk, Ohad S

2015-06-01

To relate the peculiar phenotype of amelogenesis imperfecta in a large Bedouin family to the genotype determined by whole genome linkage analysis. Amelogenesis imperfecta (AI) is a broad group of inherited pathologies affecting enamel formation, characterized by variability in phenotypes, causing mutations and modes of inheritance. Autosomal recessive or compound heterozygous mutations in FAM20A, encoding sequence similarity 20, member A, have been shown to cause several AI phenotypes. Five members from a large consanguineous Bedouin family presented with hypoplastic amelogenesis imperfecta with unerupted and resorbed permanent molars. Following Soroka Medical Center IRB approval and informed consent, blood samples were obtained from six affected offspring, five obligatory carriers and two unaffected siblings. Whole genome linkage analysis was performed followed by Sanger sequencing of FAM20A. The sequencing unravelled a novel homozygous deletion mutation in exon 11 (c.1523delC), predicted to insert a premature stop codon (p.Thr508Lysfs*6). We provide an interesting case of novel mutation in this rare disorder, in which the affected kindred is unique in the large number of family members sharing a similar phenotype.

Self-Care Adherence and Psychological Functioning of Older Patients with Type 2 Diabetes: Effects of Persuasion, Social Pressure, and Self-Efficacy.

PubMed

Yang, Fang; Pang, Joyce S; Cheng, Wendy J Y

2016-12-01

This cross-sectional study examined the role of family members' use of persuasion versus pressure as distinct forms of social control by which family members attempt to encourage better diabetes management among older adults with type 2 diabetes mellitus (T2DM). The study also examined how self-efficacy might moderate the relationship between persuasion/pressure, psychological functioning, and self-care adherence. Participants were 96 men and 103 women with T2DM, with a mean age of 63.3 years. Regression results show that neither persuasion nor pressure was significantly related to self-care adherence, but persuasion and pressure were associated in complex ways with diabetes-related emotional distress and depressive symptoms for which significant interaction effects were found. Patients with lower self-efficacy benefited from persuasion, but were adversely affected by pressure. In contrast, patients with higher self-efficacy were adversely affected by persuasion, but were less negatively affected by pressure. Findings highlight the importance of reducing pressure-based social control, considering patients' self-efficacy when family members seek to influence patients' self-care behaviors, and targeting patient-family interactions in future interventions.

Purpose To identify the underlying cause of disease in a large family with North Carolina macular dystrophy (NCMD). Methods A large four-generation family (RFS355) with an autosomal dominant form of NCMD was ascertained. Family members underwent comprehensive visual function evaluations. Blood or saliva from six affected family members and three unaffected spouses was collected and DNA tested for linkage to the MCDR1 locus on chromosome 6q12. Three affected family members and two unaffected spouses underwent whole exome sequencing (WES) and subsequently, custom capture of the linkage region followed by next-generation sequencing (NGS). Standard PCR and dideoxy sequencing were used to further characterize the mutation. Results Of the 12 eyes examined in six affected individuals, all but two had Gass grade 3 macular degeneration features. Large central excavation of the retinal and choroid layers, referred to as a macular caldera, was seen in an age-independent manner in the grade 3 eyes. The calderas are unique to affected individuals with MCDR1. Genome-wide linkage mapping and haplotype analysis of markers from the chromosome 6q region were consistent with linkage to the MCDR1 locus. Whole exome sequencing and custom-capture NGS failed to reveal any rare coding variants segregating with the phenotype. Analysis of the custom-capture NGS sequencing data for copy number variants uncovered a tandem duplication of approximately 60 kb on chromosome 6q. This region contains two genes, CCNC and PRDM13. The duplication creates a partial copy of CCNC and a complete copy of PRDM13. The duplication was found in all affected members of the family and is not present in any unaffected members. The duplication was not seen in 200 ethnically matched normal chromosomes. Conclusions The cause of disease in the original family with MCDR1 and several others has been recently reported to be dysregulation of the PRDM13 gene, caused by either single base substitutions in a DNase 1 hypersensitive site upstream of the CCNC and PRDM13 genes or a tandem duplication of the PRDM13 gene. The duplication found in the RFS355 family is distinct from the previously reported duplication and provides additional support that dysregulation of PRDM13, not CCNC, is the cause of NCMD mapped to the MCDR1 locus.

Family history is one of the most consistent risk factors for dementia. Therefore, analysis of families with a distinct inheritance pattern of disease can be a powerful approach for the identification of previously unknown disease genes. To map susceptibility regions for Alzheimer's disease. A complete genome scan with 369 microsatellite markers was carried out in 12 extended families collected in Sweden. Age at disease onset ranged from 53 to 78 years, but in 10 of the families there was at least one member with age at onset of < or =65 years. Mutations in known early-onset Alzheimer's disease susceptibility genes have been excluded. All people were genotyped for APOE, but no clear linkage with the epsilon4 allele was observed. Although no common disease locus could be found in all families, in two families an extended haplotype was identified on chromosome 8q shared by all affected members. In one of the families, a non-parametric multimarker logarithm of the odds (LOD) score of 4.2 (p = 0.004) was obtained and analysis based on a dominant model showed a parametric LOD score of 2.4 for this region. All six affected members of this family shared a haplotype of 10 markers spanning about 40 cM. Three affected members in another family also shared a haplotype in the same region. On the basis of our data, we propose the existence of a dominantly acting Alzheimer's disease susceptibility locus on chromosome 8.

Salient Multiculturalism Enhances Minority Group Members' Feelings of Power.

PubMed

Vorauer, Jacquie D; Quesnel, Matthew S

2017-02-01

The present research examined how messages advocating different intergroup ideologies affect outcomes relevant to minority group members' ability to exert power in exchanges with dominant group members. We expected that salient multiculturalism would have positive implications for minority group members' feelings of power by virtue of highlighting essential contributions they make to society, and that no such empowering effect would be evident for them in connection with alternative ideologies such as color-blindness or for dominant group members. Results across four studies involving different participant populations, operationalizations of ideology, ethnic minority groups, and experimental settings were consistent with these hypotheses and further indicated that the effects of salient multiculturalism on feelings of power had downstream implications for expectations of control in an ostensibly upcoming intergroup interaction and general goal-directed cognition.

Purpose To describe two unrelated families with multiple members demonstrating a less commonly recognized vortex pattern of corneal deposits confirmed to be granular corneal dystrophy type 1(GCD1) following identification of the p.(Arg555Trp) mutation in the transforming growth factor β-induced gene (TGFBI). Methods A slit lamp examination was performed on individuals from two families, one of Mexican descent and a second of Italian descent. Following DNA extraction from affected individuals and their unaffected relatives, TGFBI screening was performed. Results Eight of 20 individuals in the Mexican family and 20 of 55 in the Italian family demonstrated corneal stromal opacities. Seven of the eight affected individuals in the Mexican family and four of the 20 affected individuals in the Italian family demonstrated a phenotype characterized by a “sea fan” or vortex pattern of superficial stromal corneal deposits originating from the inferior aspect of the cornea. Screening of TGFBI in both families revealed a heterozygous missense mutation (p.(Arg555Trp)) in exon 12, confirming the diagnosis of GCD1. Conclusion Our findings demonstrate that GCD1 may present with a vortex pattern of anterior stromal deposits. Although this pattern of dystrophic deposits is not recognized by clinicians as a typical phenotype of GCD1, it is consistent with the production of the majority of the TGFBI protein by the corneal epithelium.

Assertive community treatment (ACT) teams are linked to high quality outcomes for individuals with severe mental illness. This paper tests arguments that influence shared between team members is associated with better encounter preparedness, higher work satisfaction, and improved performance in ACT teams. Influence is conceptualized in three ways: the average level according to team members, the team's evaluation of the dispersion of team member influence, and as the person-organization fit of individual perception of empowerment. The study design is a retrospective observational design using survey data from a longitudinal study of 26 ACT teams (approximately 275 team members total) over 18 months. This study finds that average team influence and person-organization fit are positively correlated with encounter preparedness and satisfaction. Dispersion of influence was not significantly correlated with study outcomes. Influence in ACT teams has multiple dimensions, each with differential effects on team outcomes. These findings provide guidance as to how one might encourage equal and substantive contribution from ACT team members.

Focusing on "what people want in their group" as a critical antecedent of intragroup conflict, the present study theorizes and empirically investigates the relationships among the psychological needs of group members, intragroup conflict, and group performance. It attends to the within-group average and dispersion of members' psychological needs and examines the effects stemming from group composition of needs on multiple types of conflict. The analyses based on multisource data from 145 organizational teams revealed significant relationships between the groups' composition with respect to the members' need for achievement and task conflict, need for affiliation and relationship conflict, and need for power and status conflict. Some of these relationships were moderated by open communication among members. The analyses also demonstrated that when the 3 types of conflict were considered together, task conflict was a positive predictor of group performance, whereas relationship conflict was a negative predictor. The findings highlight the motivational aspects of intragroup conflict, revealing the multilevel dynamics of the psychological needs in social settings. (c) 2014 APA, all rights reserved.

Arid and semi-arid ecosystems cover ~40% of Earth’s terrestrial surface, but we know little about how climate change will affect these widespread landscapes. Like many drylands, the Colorado Plateau in southwestern United States is predicted to experience elevated temperatures and alterations to the timing and amount of annual precipitation. We used a factorial warming and supplemental rainfall experiment on the Colorado Plateau to show that altered precipitation resulted in pronounced mortality of the widespread moss Syntrichia caninervis. Increased frequency of 1.2 mm summer rainfall events reduced moss cover from ~25% of total surface cover to <2% after only one growing season, whereas increased temperature had no effect. Laboratory measurements identified a physiological mechanism behind the mortality: small precipitation events caused a negative moss carbon balance, whereas larger events maintained net carbon uptake. Multiple metrics of nitrogen cycling were notably different with moss mortality and had significant implications for soil fertility. Mosses are important members in many dryland ecosystems and the community changes observed here reveal how subtle modifications to climate can affect ecosystem structure and function on unexpectedly short timescales. Moreover, mortality resulted from increased precipitation through smaller, more frequent events, underscoring the importance of precipitation event size and timing, and highlighting our inadequate understanding of relationships between climate and ecosystem function in drylands.

Helping faculty develop high-quality instruction that positively affects student learning can be complicated by time limitations, a lack of resources, and inexperience using student data to make iterative improvements. We describe a community of 16 faculty from five institutions who overcame these challenges and collaboratively designed, taught, iteratively revised, and published an instructional unit about the potential effect of mutations on DNA replication, transcription, and translation. The unit was taught to more than 2000 students in 18 courses, and student performance improved from preassessment to postassessment in every classroom. This increase occurred even though faculty varied in their instructional practices when they were teaching identical materials. We present information on how this faculty group was organized and facilitated, how members used student data to positively affect learning, and how they increased their use of active-learning instructional practices in the classroom as a result of participation. We also interviewed faculty to learn more about the most useful components of the process. We suggest that this professional development model can be used for geographically separated faculty who are interested in working together on a known conceptual difficulty to improve student learning and explore active-learning instructional practices.

2017-04-01

The rapidly changing demographics of the United States workforce include a large number of women and members of minority groups that are currently underrepresented in science and engineering-related education and careers. Recent research indicates that while singular incidents of sexism do exist, gender bias more often affects women in various subtle ways. The effects of stereotype threat and the lack of appropriate mentoring and female role models are samples of the possible factors contributing to performance and longevity for women in math-intensive fields. To address how this issue affects those in radiation protection, the current status of women in the field is reviewed as a progression through the scientific pipeline, from education and employment to positions in scientific bodies and professional recognition, with primary focus on American women and institutions. Racial diversity demographics are reviewed where available. Findings indicate women and minority racial groups are underrepresented in multiple aspects of education, research, and leadership. While gender diversity across the field has not yet reached gender parity, trending indicates that the percentage of women earning degrees in radiation protection has consistently increased over the last four decades. Diversity of racial groups, however, has remained fairly consistent and is well below national averages. Diverse perspectives have been documented in collective problem-solving to lead to more innovative solutions.

To explore factors affecting sustaining employment in people with acquired brain injury (ABI). A multiple case study approach using semi-structured interviews in eight cases (29 individuals). Each case included an individual with ABI, a family member, a job coach and a co-worker (triangulation). The eight individuals with ABI had completed vocational rehabilitation and were purposely selected based on whether they had sustained employment (4) or not (4). Similarity between pre-injury work or leisure interest and post-injury work, unconditional motivation, insight and the ability to cope with cognitive and behavioural sequelae were beneficial in sustaining employment. Post-injury instances of poor cognitive or behavioural function did not necessarily affect sustained employment. The vocational rehabilitation programme was beneficial in building up confidence, providing continued follow up and providing co-worker 'twins' in the work place. Employers with a personal experience of disability helped individuals with ABI to sustain employment. Similarities between pre-injury work or leisure interests and post-injury work improved motivation. Factors associated with sustained employment were insightful, unconditional, internal motivation providing an ability to cope, confidence provided by ongoing vocational rehabilitation support through job coaches, supportive co-workers and employers with a personal experience of disability. People with ABI can be outstanding employees.

The role of community context in planning and implementing community-based health promotion projects.

The current study examines how community context affected collaborative planning and implementation in eight sites participating in a healthy cities and communities initiative in California. Data are from 23 focus groups conducted with coalition members, and 76 semi-structured interviews with local coordinators and community leaders. Multiple case study methods were used to identify major themes related to how five contextual domains influenced collaborative planning and implementation. Results showed that history of collaboration can influence resources and interpersonal and organizational connections available for planning and implementation, as well as priorities selected for action. Community politics and history can affect which segments of the community participate in a planning process and what issues are prioritized, as well as the pool of partners willing to aid in implementation. Some community norms and values bring people together and others appear to limit involvement from certain groups. Community demographics and economic conditions may shape outreach strategies for planning and implementation, and may also shape priorities. Geography can play a role in assessment methods, priority selection, partners available to aid in implementation, and participation in activities and events. Results suggest that community context plays a substantive role in shaping how community-based health promotion projects unfold. Copyright © 2011 Elsevier Ltd. All rights reserved.

2011-01-01

This study used real-time electronic surveys delivered through mobile phones, known as Ecological Momentary Assessment (EMA), to determine whether level and experience of leisure-time physical activity differ across children's physical and social contexts. Children (N = 121; ages 9 to 13 years; 52% male, 32% Hispanic/Latino) participated in 4 days (Fri.-Mon.) of EMA during nonschool time. Electronic surveys (20 total) assessed primary activity (eg, active play/sports/exercise), physical location (eg, home, outdoors), social context (eg, friends, alone), current mood (positive and negative affect), and enjoyment. Responses were time-matched to the number of steps and minutes of moderate-to-vigorous physical activity (MVPA; measured by accelerometer) in the 30 minutes before each survey. Mean steps and MVPA were greater outdoors than at home or at someone else's house (all P < .05). Steps were greater with multiple categories of company (eg, friends and family together) than with family members only or alone (all P < .05). Enjoyment was greater outdoors than at home or someone else's house (all P < .05). Negative affect was greater when alone and with family only than friends only (all P < .05). Results describing the value of outdoor and social settings could inform context-specific interventions in this age group.

Cultural Historical Activity Theory served as the analytical framework for the study of a professional development event for a zoo's education department, specifically designed to build understandings of "Affective Transformation," an element pertinent to the organization's strategic plan. Three key products—an Affective Transformation model, scaffolding schematic, and definition, "providing emotional experiences for visitors which increase caring for animals and nature that may lead to zoo-related nature-protective behaviors"—emerged as a result of ongoing deliberation among professional development community members over two days. Participants, including both management- and non-management-level staff, as well as an expert facilitator, contributed complementary expertise to the process. The discussions, therefore, crossed both vertical and horizontal layers of authority. Moreover, leadership was distributed across these levels in the development of these products. Members used pre-existing resources, as well as tools created in the course of the professional development event. Interactions among participants and resources were instrumental in Affective Transformation product development. Examination of one zoo's construction of understanding of affective goals, therefore, may offer insights to other organizations with similar aspirations.

Background Globally 68 million people are infected with lymphatic filariasis (LF), 17 million of whom have lymphedema. This study explores the effects of a lymphedema management program in Odisha State, India on morbidity and psychosocial effects associated with lymphedema. Methodology/Principal Findings Focus groups were held with patients (eight groups, separated by gender), their family members (eight groups), community members (four groups) and program volunteers (four groups) who had participated in a lymphedema management program for the past three years. Significant social, physical, and economic difficulties were described by patients and family members, including marriageability, social stigma, and lost workdays. However, the positive impact of the lymphedema management program was also emphasized, and many family and community members indicated that community members were accepting of patients and had some improved understanding of the etiology of the disease. Program volunteers and community members stressed the role that the program had played in educating people, though interestingly, local explanations and treatments appear to coexist with knowledge of biomedical treatments and the mosquito vector. Conclusions/Significance Local and biomedical understandings of disease can co-exist and do not preclude individuals from participating in biomedical interventions, specifically lymphedema management for those with lymphatic filariasis. There is a continued need for gender-specific psychosocial support groups to address issues particular to men and women as well as a continued need for improved economic opportunities for LF-affected patients. There is an urgent need to scale up LF-related morbidity management programs to reduce the suffering of people affected by LF. PMID:26849126

Targeting BCL-2-like Proteins to Kill Cancer Cells.

2016-08-01

Mutations that impair apoptosis contribute to cancer development and reduce the effectiveness of conventional anti-cancer therapies. These insights and understanding of how the B cell lymphoma (BCL)-2 protein family governs apoptosis have galvanized the search for a new class of cancer drugs that target its pro-survival members by mimicking their natural antagonists, the BCL-2 homology (BH)3-only proteins. Successful initial clinical trials of the BH3 mimetic venetoclax/ABT-199, specific for BCL-2, have led to its recent licensing for refractory chronic lymphocytic leukemia and to multiple ongoing trials for other malignancies. Moreover, preclinical studies herald the potential of emerging BH3 mimetics targeting other BCL-2 pro-survival members, particularly myeloid cell leukemia (MCL)-1, for multiple cancer types. Thus, BH3 mimetics seem destined to become powerful new weapons in the arsenal against cancer. This review sketches the discovery of the BCL-2 family and its impact on cancer development and therapy; describes how interactions of family members trigger apoptosis; outlines the development of BH3 mimetic drugs; and discusses their potential to advance cancer therapy.

Diatoms are phytoplanktonic organisms that grow successfully in the ocean where light conditions are highly variable. Studies of the molecular mechanisms of light acclimation in the marine diatom Phaeodactylum tricornutum show that carotenoid de-epoxidation enzymes and LHCX1, a member of the light-harvesting protein family, both contribute to dissipate excess light energy through non-photochemical quenching (NPQ). In this study, we investigate the role of the other members of the LHCX family in diatom stress responses. Our analysis of available genomic data shows that the presence of multiple LHCX genes is a conserved feature of diatom species living in different ecological niches. Moreover, an analysis of the levels of four P. tricornutum LHCX transcripts in relation to protein expression and photosynthetic activity indicates that LHCXs are differentially regulated under different light intensities and nutrient starvation, mostly modulating NPQ capacity. We conclude that multiple abiotic stress signals converge to regulate the LHCX content of cells, providing a way to fine-tune light harvesting and photoprotection. Moreover, our data indicate that the expansion of the LHCX gene family reflects functional diversification of its members which could benefit cells responding to highly variable ocean environments.

Construct the stable vendor managed inventory partnership through a profit-sharing approach

In real life, the vendor managed inventory (VMI) model is not always a stable supply chain partnership. This paper proposes a cooperative game based profit-sharing method to stabilize the VMI partnership. Specifically, in a B2C setting, we consider a VMI program including a manufacturer and multiple online retailers. The manufacturer provides the finished product at the equal wholesale price to multiple online retailers. The online retailers face the same customer demand information. We offer the model to compute the increased profits generated by information sharing for total possible VMI coalitions. Using the solution concept of Shapley value, the profit-sharing scheme is produced to fairly divide the total increased profits among the VMI members. We find that under a fair allocation scheme, the higher inventory cost of one VMI member increases the surplus of the other members. Furthermore, the manufacturer is glad to increase the size of VMI coalition, whereas, the retailers are delighted to limit the size of the alliance. Finally, the manufacturer can select the appropriate retailer to boost its surplus, which has no effect on the surplus of the other retailers. The numerical examples indicate that the grand coalition is stable under the proposed allocation scheme.

Advances in cancer research and personalized medicine will require significant new bridging infrastructures, including more robust biorepositories that link human tissue to clinical phenotypes and outcomes. In order to meet that challenge, four cancer centers formed the TIES Cancer Research Network, a federated network that facilitates data and biospecimen sharing among member institutions. Member sites can access pathology data that is de-identified and processed with the TIES natural language processing system, which creates a repository of rich phenotype data linked to clinical biospecimens. TIES incorporates multiple security and privacy best practices that, combined with legal agreements, network policies and procedures, enable regulatory compliance. The TIES Cancer Research Network now provides integrated access to investigators at all member institutions, where multiple investigator-driven pilot projects are underway. Examples of federated search across the network illustrate the potential impact on translational research, particularly for studies involving rare cancers, rare phenotypes, and specific biologic behaviors. The network satisfies several key desiderata including local control of data and credentialing, inclusion of rich phenotype information, and applicability to diverse research objectives. The TIES Cancer Research Network presents a model for a national data and biospecimen network. PMID:26670560

Genome structure drives patterns of gene family evolution in ciliates, a case study using Chilodonella uncinata (Protista, Ciliophora, Phyllopharyngea)

In most lineages, diversity among gene family members results from gene duplication followed by sequence divergence. Because of the genome rearrangements during the development of somatic nuclei, gene family evolution in ciliates involves more complex processes. Previous work on the ciliate Chilodonella uncinata revealed that macronuclear β-tubulin gene family members are generated by alternative processing, in which germline regions are alternatively used in multiple macronuclear chromosomes. To further study genome evolution in this ciliate, we analyzed its transcriptome and found that: 1) alternative processing is extensive among gene families; and 2) such gene families are likely to be C. uncinata-specific. We characterized additional macronuclear and micronuclear copies of one candidate alternatively processed gene family -- a protein kinase domain containing protein (PKc) -- from two C. uncinata strains. Analysis of the PKc sequences reveals: 1) multiple PKc gene family members in the macronucleus share some identical regions flanked by divergent regions; and 2) the shared identical regions are processed from a single micronuclear chromosome. We discuss analogous processes in lineages across the eukaryotic tree of life to provide further insights on the impact of genome structure on gene family evolution in eukaryotes. PMID:24749903

Purple acid phosphatases (PAPs) play an important role in plant phosphorus nutrition, both by liberating phosphorus from organic sources in the soil and by modulating distribution within the plant throughout growth and development. Furthermore, members of the PAP protein family have been implicated in a broader role in plant mineral homeostasis, stress responses and development. We have identified 33 candidate PAP encoding gene models in the maize (Zea mays ssp. mays var. B73) reference genome. The maize Pap family includes a clear single-copy ortholog of the Arabidopsis gene AtPAP26, shown previously to encode both major intracellular and secreted acid phosphatase activities. Certain groups of PAPs present in Arabidopsis, however, are absent in maize, while the maize family contains a number of expansions, including a distinct radiation not present in Arabidopsis. Analysis of RNA-sequencing based transcriptome data revealed accumulation of maize Pap transcripts in multiple plant tissues at multiple stages of development, and increased accumulation of specific transcripts under low phosphorus availability. These data suggest the maize PAP family as a whole to have broad significance throughout the plant life cycle, while highlighting potential functional specialization of individual family members.

Exercise training within the pulmonary rehabilitation (PR) context is considered the most effective strategy to reduce COPD symptoms. However, participation in PR and continued exercise training following program completion are low. Previous research examined factors related to attendance and adherence, but the knowledge base to date has been limited to quantitative findings that focus solely on participants diagnosed with COPD. In addition to quantitative research, exploring multiple perspectives (eg, PR participants, significant others, staff, and stakeholders) using qualitative research methods opens a window of additional understanding. The goal of this study was to obtain multiple perspectives on PR to gain insight into factors that affect exercise participation among individuals diagnosed with COPD. A total of 26 participants were interviewed via telephone, including 8 individuals diagnosed with COPD (4 men and 4 women, mean age of 67 [range of 58-77] y), 4 family members, 11 PR staff, and 3 community stakeholders. Analysis revealed 3 themes: task self-efficacy for exercise, provision of support and encouragement, and perceptions of gender differences. Despite initial concerns, individuals diagnosed with COPD reported becoming more confident during PR and emphasized the importance of being supported by staff. PR staff perceived that men tended to approach exercise in a more eager and aggressive manner compared with women, who were more cautious and hesitant. In addition to enhancing task self-efficacy, findings suggest that exercise participation and adherence within the PR environment may be improved by adopting a gender-tailored approach.

The common γ molecule (γc) is a shared signaling receptor subunit used by six γc-cytokines. These cytokines play crucial roles in the differentiation of the mature immune system and are involved in many human diseases. Moreover, recent studies suggest that multiple γc-cytokines are pathogenically involved in a single disease, thus making the shared γc-molecule a logical target for therapeutic intervention. However, the current therapeutic strategies seem to lack options to treat such cases, partly because of the lack of appropriate neutralizing antibodies recognizing the γc and, more importantly, because of the inherent and practical limitations in the use of monoclonal antibodies. By targeting the binding interface of the γc and cytokines, we successfully designed peptides that not only inhibit multiple γc-cytokines but with a selectable target spectrum. Notably, the lead peptide inhibited three γc-cytokines without affecting the other three or non-γc-cytokines. Biological and mutational analyses of our peptide provide new insights to our current understanding on the structural aspect of the binding of γc-cytokines the γc-molecule. Furthermore, we provide evidence that our peptide, when conjugated to polyethylene glycol to gain stability in vivo, efficiently blocks the action of one of the target cytokines in animal models. Collectively, our technology can be expanded to target various combinations of γc-cytokines and thereby will provide a novel strategy to the current anti-cytokine therapies against immune, inflammatory, and malignant diseases.

Multiple treatments are available for osteoporosis; however, little is known about treatment change patterns and associated factors. Osteoporosis treatment change patterns, discontinuation and factors associated with treatment change in members of a large national health plan were examined. A retrospective cohort study was conducted in 7315 commercial and 34 146 Medicare Advantage Prescription Drug (MAPD) members newly initiated on an osteoporosis medication between 2006 and 2008. Osteoporosis treatment change, discontinuation and re-initiation patterns were assessed. Multivariate logistic regression was used to examine factors associated with treatment change. Commercial and MAPD members were assessed separately because of differences in demographics and insurance benefits. Approximately 12% of members had a change in index therapy within 12 months. Almost 60% of members discontinued the index medication at least once, based on a 90-day refill gap. Over 40% of members discontinued all osteoporosis medications by the end of 12 months post-index. Among MAPD and commercial members, women and those with risedronate, ibandronate or calcitonin at index, index therapy in 2008 and an osteoporosis diagnosis were more likely to have a treatment change while members with health plans other than health maintenance organizations and generic alendronate at index were less likely to have a treatment change. Osteoporosis treatment change occurred in approximately 12% of members, while a greater proportion of members discontinued treatment completely within 12 months. Member characteristics may be used to predict therapy change for evaluation and quality initiatives within a health plan. © 2011 Blackwell Publishing Ltd.

This study examined the prevalence of perceived stress and depressive symptoms in cancer survivors and their family members compared with subjects without cancer and without family members with cancer. The subjects of this cross-sectional study were adults ≥19 years old who participated in the 2012 Korea Community Health Survey. Stress and depressive symptoms in cancer survivors and their family members were assessed and compared to symptoms in control groups by chi-square tests and multiple logistic regression analyses. Of the 6783 cancer survivors, 26.9% and 8.7% reported having stress and depressive symptoms, respectively, and 27.7% and 5.9% of family members of cancer survivors reported having stress and depressive symptoms, respectively. Cancer survivors showed higher adjusted odds ratio (aOR) for stress (aOR = 1.26, 95% confidence interval (CI) = 1.16-1.37) and depressive symptoms (aOR = 1.82, 95% CI = 1.57-2.11) than subjects without cancer history. Family members of cancer survivors showed a higher OR for stress and depressive symptoms than subjects without a family member who survived cancer. Cancer survivors and family members of cancer survivors had more stress and depressive symptoms than controls. Careful management for cancer patients and their family members should include screening for stress and depression to improve mental health associated with cancer survivorship.

PatientsLikeMe: Consumer Health Vocabulary as a Folksonomy

PubMed Central

Smith, Catherine Arnott; Wicks, Paul J.

2008-01-01

PatientsLikeMe is an online social networking community for patients. Subcommunities center on three distinct diagnoses: Amyotrophic Lateral Sclerosis, Multiple Sclerosis and Parkinson’s Disease. Community members can describe their symptoms to others in natural language terms, resulting in folksonomic tags available for clinical analysis and for browsing by other users to find “patients like me”. Forty-three percent of PatientsLikeMe symptom terms are present as exact (24%) or synonymous (19%) terms in the Unified Medical Language System Metathesaurus (National Library of Medicine; 2007AC). Slightly more than half of the symptom terms either do not match the UMLS, or are unclassifiable. A clinical vocabulary, SNOMED CT, accounts for 93% of the matching terms. Analysis of the failed matches reveals challenges for online patient communication, not only with healthcare professionals, but with other patients. In a Web 2.0 environment with lowered barriers between consumers and professionals, a deficiency in knowledge representation affects not only the professionals, but the consumers as well.

Grimm, Christian; Chen, Cheng-Chang; Wahl-Schott, Christian; Biel, Martin

2017-01-01

Two-pore channels (TPCs) have recently emerged as a novel class of non-selective cation channels in the endolysosomal system. There are two members in the human genome, TPC1 and TPC2. Studies with TPC knockout and knockdown models have revealed that these channels participate in the regulation of multiple endolysosomal trafficking pathways which when dysregulated can lead to or influence the development of a range of different diseases such as lysosomal storage, metabolic, or infectious diseases. TPCs have been demonstrated to be activated by different endogenous stimuli, PI(3,5)P2 and NAADP, and ATP has been found to block TPC activation via mTOR. Loss of TPCs can lead to obesity and hypercholesterolemia, and to a slow-down of intracellular virus and bacterial toxin trafficking, it can affect VEGF-induced neoangiogenesis, autophagy, human hair pigmentation or the acrosome reaction in sperm. Moreover, physiological roles of TPCs in cardiac myocytes and pancreatic β cells have been postulated. PMID:28223936

Public health is what we do together as a society to ensure the conditions in which everyone can be healthy. Although many sectors play key roles, governmental public health is an essential component. Recent stressors on public health are driving many local governments to pioneer a new Public Health 3.0 model in which leaders serve as Chief Health Strategists, partnering across multiple sectors and leveraging data and resources to address social, environmental, and economic conditions that affect health and health equity. In 2016, the US Department of Health and Human Services launched the Public Health 3.0 initiative and hosted listening sessions across the country. Local leaders and community members shared successes and provided insight on actions that would ensure a more supportive policy and resource environment to spread and scale this model. This article summarizes the key findings from those listening sessions and recommendations to achieve Public Health 3.0. PMID:28880837

"Photographing money" [1]is a self-service model under the mobile Internet. The task pricing is reasonable, related to the success of the commodity inspection. First of all, we analyzed the position of the mission and the membership, and introduced the factor of membership density, considering the influence of the number of members around the mission on the pricing. Multivariate regression of task location and membership density using MATLAB to establish the mathematical model of task pricing. At the same time, we can see from the life experience that membership reputation and the intensity of the task will also affect the pricing, and the data of the task success point is more reliable. Therefore, the successful point of the task is selected, and its reputation, task density, membership density and Multiple regression of task positions, according to which a nhew task pricing program. Finally, an objective evaluation is given of the advantages and disadvantages of the established model and solution method, and the improved method is pointed out.

Public health is what we do together as a society to ensure the conditions in which everyone can be healthy. Although many sectors play key roles, governmental public health is an essential component. Recent stressors on public health are driving many local governments to pioneer a new Public Health 3.0 model in which leaders serve as Chief Health Strategists, partnering across multiple sectors and leveraging data and resources to address social, environmental, and economic conditions that affect health and health equity. In 2016, the US Department of Health and Human Services launched the Public Health 3.0 initiative and hosted listening sessions across the country. Local leaders and community members shared successes and provided insight on actions that would ensure a more supportive policy and resource environment to spread and scale this model. This article summarizes the key findings from those listening sessions and recommendations to achieve Public Health 3.0.
