    PURPOSE: The purpose of this study was to examine the relationship between psychological and social factors and diabetes outcomes in people with type 2 diabetes and their family members. METHODS: A total of 153 patients with type 2 diabetes were assessed at a diabetes outpatient clinic and postal questionnaires were sent to nominated family members. The measures examined were diabetes knowledge, social support, well-being, and illness perceptions. RESULTS: When compared with those with diabetes, family members reported lower positive well-being and lower levels of satisfaction with support. They also perceived diabetes as a more cyclical illness, which was controlled more by treatment than by the individual. Family members also reported that the person with diabetes was more emotionally distressed and knew more about diabetes than the patient had actually reported himself or herself. There were no differences between the family members of those in good or poor glycaemic control. CONCLUSIONS: This study reinforces the importance of understanding social context and illness beliefs in diabetes management. It also highlights the potential for including family members in discussions and education about diabetes management.

    Health care interventions may affect the health of patients’ family networks. It has been suggested that these “health spillovers” should be included in economic evaluation, but there is not a systematic method for doing this. In this article, we develop a framework for including health spillovers in economic evaluation. We focus on extra-welfarist economic evaluations where the objective is to maximize health benefits from a health care budget (the “health care perspective”). Our framework involves adapting the conventional cost-effectiveness decision rule to include 2 multiplier effects to internalize the spillover effects. These multiplier effects express the ratio of total health effects (for patients and their family networks) to patient health effects. One multiplier effect is specified for health benefit generated from providing a new intervention, one for health benefit displaced by funding this intervention. We show that using multiplier effects to internalize health spillovers could change the optimal funding decisions and generate additional health benefits to society. PMID:26377370

  8. The Cretan Script Family Includes the Carian Alphabet

    Directory of Open Access Journals (Sweden)

    Revesz Peter Z.

    2017-01-01

    Full Text Available The Cretan Script Family is a set of related writing systems that have a putative origin in Crete. Recently, Revesz [11] identified the Cretan Hieroglyphs, Linear A, Linear B, the Cypriot syllabary, and the Greek, Old Hungarian, Phoenician, South Arabic and Tifinagh alphabets as members of this script family and using bioinformatics algorithms gave a hypothetical evolutionary tree for their development and presented a map for their likely spread in the Mediterranean and Black Sea areas. The evolutionary tree and the map indicated some unknown writing system in western Anatolia to be the common origin of the Cypriot syllabary and the Old Hungarian alphabet. This paper argues that the missing link may be some ancestor of the Carian alphabet because several Carian alphabet letters show an intermediate stage between the corresponding Cypriot syllabary signs and the Old Hungarian letters.

    In the present retrospektive study the situation of the natural crown as well as the restoration types placed prior to endodontic treatment was examined. A total of 782 teeth from 545 patients (54.3% men; 45.7% women; mean age: 49.9 +/- 12.1 years) were investigated. In addition to the evaluation of the medical history of the patients, x-rays and a clinical investigation were carried out in order to assess the clinical condition of the crown as well as the restoration types. Of special interest were: carious lesions, composite fillings, amalgam, ceramic or gold crowns and/or bridge restorations. 305 of the examined teeth were located in the mandible and 477 in the maxilla. 26.3% of the teeth were anteriors, 31.2% were premolars and 42.5% were molars. 24.2% of the teeth were restored with metal ceramic crowns, 15.1% were restored with gold cast crowns or served as abutment teeth for bridgework; untreated caries was found in 21.1%, and composite fillings were found in 13.7% of the cases. 23.8% of the front teeth, 26.6% of the premolars and 22.6% of the molars showed a metal ceramic restoration. 21% of all carious defects were found in the maxilla as well as in the mandible. In addition to the high number of untreated carious lesions, the presence of metal ceramics restorations was significantly higher than other restorations types. Carious lesions are main aetiological factors for endodontic measures, but also ceramic restorations including premature contacts have to be considered as causal factors for pulpal irritations.

  13. New organ transplant policies in Japan, including the family-oriented priority donation clause.

    Science.gov (United States)

    Aita, Kaoruko

    2011-03-15

    The revised Organ Transplant Law in Japan that took effect in July 2010 allows organ procurement from brain-dead individuals, including children, only with family consent. The amended law also allows individuals to prioritize family members to receive their donated organs after death. This policy differs from the prioritization policy in Israel, which provides incentives to individuals who agree to help each other in society and rectifies the problem of free riders, individuals who are willing to accept an organ but refuse to donate. Despite these differences, however, the Japanese and Israeli policies have revealed new ethical dilemmas, including the fear of compromising fairness in organ allocation.

    Much of the existing research on shared decision-making in hospice and palliative care focuses on the provider-patient dyad; little is known about shared decision-making that is inclusive of family members of patients with advanced disease. We sought to describe shared decision-making as it occurred in hospice interdisciplinary team meetings that included family caregivers as participants using video-conferencing technology. We conducted a multimethod study in which we used content and thematic analysis techniques to analyze video-recordings of hospice interdisciplinary team meetings (n = 100), individual interviews of family caregivers (n = 73) and hospice staff members (n = 78), and research field notes. Participants in the original studies from which data for this analysis were drawn were hospice family caregivers and staff members employed by one of five different community-based hospice agencies located in the Midwestern United States. Shared decision-making occurred infrequently in hospice interdisciplinary team meetings that included family caregivers. Barriers to shared decision-making included time constraints, communication skill deficits, unaddressed emotional needs, staff absences, and unclear role expectations. The hospice philosophy of care, current trends in healthcare delivery, the interdisciplinary nature of hospice teams, and the designation of a team leader/facilitator supported shared decision-making. The involvement of family caregivers in hospice interdisciplinary team meetings using video-conferencing technology creates a useful platform for shared decision-making; however, steps must be taken to transform family caregivers from meeting attendees to shared decision-makers. © The Author(s) 2015.

    Family carers, as a "shadow workforce", are foundational to the day-to-day integration of health service delivery for older family members living with complex health needs. This paper utilises Haggerty's model of continuity of care to explore the contribution of family carers' to the provision of care and support for an older family member's chronic condition within the context of health service delivery. We analysed data from interviews of 13 family carers in a case study of primary health care in New Zealand - a Maori Provider Organisation - to determine the alignment of family caregiving with the three levels of continuity of care (relational continuity, informational continuity, and management continuity). We found alignment of family caregiving tasks, responsibilities, and relationships with the three levels of continuity of care. Family carers 1) partnered with providers to extend chronic care to the home; 2) transferred and contributed information from one provider/service to another; 3) supported consistent and flexible management of care. The Maori Provider Organisation supported family carer-provider partnership enabled by shared Maori cultural values and social mandate of building family-centred wellbeing. Relational continuity was the most important level of continuity of care; it sets precedence for family carers and providers to establish the other levels - informational and management - continuity of care for their family member cared for. Family carers need to be considered as active partners working alongside responsive primary health care providers and organisation in the implementation of chronic care.

  18. Should nutritional status evaluation be included in the initial needs assessment of leprosy patients with disability prior to socio-economic.

    Because of the large numbers of leprosy patients with disability and the limited resources available, it is important that socio-economic rehabilitation (SER) is targeted towards those who are most in need. Towards this purpose, current assessments of leprosy patients prior to initiating SER include the evaluation of income, assets and household possessions. Conspicuously absent is the nutritional assessment of the patient. In the absence of weight loss associated with illness, population studies indicate that undernutrition reflects poor socio-economic conditions. In this study of 151 cured leprosy patients with disability, 57% of the patients were found to be undernourished using body mass index (kg/m2) derived from body weight and height, and 10% of the patients were severely undernourished (grade III). Undernutrition in the patients was poorly though significantly correlated with personal income (r = 0.18, P nutritional status evaluation by anthropometry as part of the initial screening of leprosy patients prior to instituting SER. We believe that this simple and objective evaluation can add to the assessment of 'threat' of economic deprivation or actual economic 'dislocation', and thus help in the prioritization of leprosy patients for SER.

  1. Included or Excluded: An Analysis of the Application of the Free, Prior and Informed Consent Principle in Land Grabbing Cases in Cameroon

    Directory of Open Access Journals (Sweden)

    Jean-Claude N Ashukem

    2016-09-01

    Full Text Available Even though the principle of free, prior and informed consent (FPIC is soft law, the need to respect, protect and fulfil the rights to be informed and to be involved in development projects is strongly backed in international legal instruments including inter alia the ILO Convention 169 Concerning Indigenous and Tribal People in Independent Countries (1998 and the UN Declaration on the Rights of Indigenous and Tribal People (2007. These instruments do not only appear to be the most comprehensive and advanced international legal instruments that deal with indigenous peoples' rights in terms of the FPIC, but also signal an addition to the growing body of international human rights law that serves to ensure the realisation and protection of the substantive environmental and other human rights of indigenous people, particularly in the context of land grabbing activities that have the potential to negatively impact on their rights. Such rights include, for example, the rights to be informed and to participate in decision-making processes with respect to development projects, including land grabbing activities. This implies an obligation on states party to such international agreements to ensure that indigenous people are informed about and are actively involved in both the negotiation and the implementation of land grabbing deals. However, because the latter often takes place against the background of non-transparent transactions which are inimical to the rights and interests of indigenous people, one may wonder why the principle of FPIC is not applicable during land grabbing transactions. Focusing on Cameroon, this article examines instances of land grabbing in the country in order to support this hypothesis. This is done by focusing specifically on the application of the principle of FPIC. The arguments in the article are inspired by international law in which the application of the principle in the context of land grabbing serves not only to

    We report a new family with autosomal dominant epilepsy with auditory features (ADEAF) including focal cortical dysplasia (FCD) in the proband. We aim to identify the molecular cause in this family and clarify the relationship between FCD and ADEAF. A large Iranian Jewish family including 14 individuals with epileptic seizures was phenotyped including high-resolution 3-T MRI. We performed linkage analysis and exome sequencing. LGI1, KANK1 and RELN were Sanger sequenced. Seizure semiology of 11 individuals was consistent with ADEAF. The proband underwent surgery for right mesiotemporal FCD. 3-T MRIs in four individuals were unremarkable. Linkage analysis revealed peaks on chromosome 9p24 (LOD 2.43) and 10q22-25 (LOD 2.04). A novel heterozygous LGI1 mutation was identified in all affected individuals except for the proband indicating a phenocopy. Exome sequencing did not reveal variants within the chromosome 9p24 region. Closely located variants in KANK1 and a RELN variant did not segregate with the phenotype. We provide detailed description of the phenotypic spectrum within a large ADEAF family with a novel LGI1 mutation that was conspicuously absent in the proband with FCD, demonstrating that despite identical clinical symptoms, phenocopies in ADEAF families may exist. This family illustrates that rare epilepsy syndromes within a single family can have both genetic and structural etiologies.

    This report presents multimodal imaging of a 27-year-old woman diagnosed with benign familial fleck retina (OMIM 228980), an uncommon disorder. Fundus photographs revealed retinal flecks that affected her post-equatorial retina but spared the macular area. Fundus autofluorescence and infrared imaging demonstrated a symmetrical pattern of yellow-white fleck lesions that affected both eyes. Her full-field electroretinogram and electrooculogram were normal. An optical coherence tomography B-scan was performed for both eyes, revealing increased thickness of the retinal pigmented epithelium leading to multiple small pigmented epithelium detachments. The outer retina remained intact in both eyes. Spectral-domain optical coherence tomography angiography with split-spectrum amplitude decorrelation algorithm and 3 × 3 mm structural en face optical coherence tomography did not show macular lesions. Benign familial fleck retina belongs to a heterogenous group of so-called flecked retina syndromes, and should be considered in patients with yellowish-white retinal lesions without involvement of the macula.

    Full Text Available n a gap in consistent application of system-level strategies that can effectively translate organizational policies around patient and family engagement into practice. Methods The broad objective of this initiative was to develop a system-level implementation strategy to include patient and family advisors (PFAs at decision-making points in primary healthcare (PHC based on wellestablished evidence and literature. In this opportunity sponsored by the Canadian Foundation for Healthcare Improvement (CFHI a co-design methodology, also well-established was applied in identifying and developing a suitable implementation strategy to engage PFAs as members of quality teams in PHC. Diabetes management centres (DMCs was selected as the pilot site to develop the strategy. Key steps in the process included review of evidence, review of the current state in PHC through engagement of key stakeholders and a co-design approach. Results The project team included a diverse representation of members from the PHC system including patient advisors, DMC team members, system leads, providers, Public Engagement team members and CFHI improvement coaches. Key outcomes of this 18-month long initiative included development of a working definition of patient and family engagement, development of a Patient and Family Engagement Resource Guide and evaluation of the resource guide. Conclusion This novel initiative provided us an opportunity to develop a supportive system-wide implementation plan and a strategy to include PFAs in decision-making processes in PHC. The well-established co-design methodology further allowed us to include value-based (customer driven quality and experience of care perspectives of several important stakeholders including patient advisors. The next step will be to implement the strategy within DMCs, spread the strategy PHC, both locally and provincially with a focus on sustainability.

    To explore patient and family perceptions of team effectiveness of teams those include nurse practitioners in acute and primary care. Nurse practitioners provide safe and effective care. Patients are satisfied with the care provided by nurse practitioners. Research examining patient and family perceptions of team effectiveness following the implementation of nurse practitioners in teams is lacking. A descriptive qualitative design was used. We used purposeful sampling to identify participants in four clinical specialties. We collected data from March 2014-January 2015 using semi-structured interviews and demographic questionnaires. Content analysis was used. Descriptive statistics were generated. Participants (n = 49) believed that the teams were more effective after the implementation of a nurse practitioner and this was important to them. They described processes that teams with nurse practitioners used to effectively provide care. These processes included improved communication, involvement in decision-making, cohesion, care coordination, problem-solving, and a focus on the needs of patients and families. Participants highlighted the importance of interpersonal team dynamics. A human approach, trust, being open to discussion, listening to patient and family concerns and respect were particularly valued by participants. Different processes emerged as priorities when data were examined by speciality. However, communication, trust and taking the time to provide care were the most important processes. The study provides new insights into the views of patients and families and micro-level processes in teams with nurse practitioners. The relative importance of each process varied according to the patient's health condition. Patients and providers identified similar team processes. Future research is needed to identify how team processes influence care outcomes. The findings can support patients, clinicians and decision-makers to determine the processes to focus on to

    2017-12-01

    This Université du Québec en Outaouais study examined professionals' attitudes towards fathers, their perceived self-efficacy when working with them and their perceptions of the importance of including fathers in family interventions. Professionals in Québec, Canada, working in childcare fields such as education, social services, health, community services and management answered a self-report questionnaire between 2013 and 2015. The 296 respondents (90% females) had a mean age of 39 (20-65), were from urban, semi-urban and rural settings and provided services to families with children up to five years of age. Social service professionals perceived fathers more negatively than did other professionals. Even though male professionals perceived fathers more negatively, they felt more confident working with them than did their female counterparts. Positive perceptions of fathers were associated with more favourable attitudes towards including them in family interventions, and this association was mediated by the professionals' perceptions of their own self-efficacy. The most negative attitudes were reported by social service professionals. Male professionals viewed fathers more negatively but were more confident working with them than were female colleagues. Improving professionals' perceptions of fathers could help to promote their inclusion in family interventions. ©2017 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

    A number of actinomycetes isolated from soil were found to produce one or more members of a new family of antibiotics, the cephamycins, which are structurally related to cephalosporin C. The cephamycins were produced in submerged fermentation in a wide variety of media by one or more of eight different species of Streptomyces, including a newly described species, S. lactamdurans. These antibiotics exhibit antibacterial activity against a broad spectrum of bacteria which includes many that are resistant to the cephalosporins and penicillins. PMID:4790552

    Recent evidence shows that patient engagement is an important strategy in achieving a high performing healthcare system. While there is considerable evidence of implementation initiatives in direct care context, there is limited investigation of implementation initiatives in decision-making context as it relates to program planning, service delivery and developing policies. Research has also shown a gap in consistent application of system-level strategies that can effectively translate organizational policies around patient and family engagement into practice. The broad objective of this initiative was to develop a system-level implementation strategy to include patient and family advisors (PFAs) at decision-making points in primary healthcare (PHC) based on wellestablished evidence and literature. In this opportunity sponsored by the Canadian Foundation for Healthcare Improvement (CFHI) a co-design methodology, also well-established was applied in identifying and developing a suitable implementation strategy to engage PFAs as members of quality teams in PHC. Diabetes management centres (DMCs) was selected as the pilot site to develop the strategy. Key steps in the process included review of evidence, review of the current state in PHC through engagement of key stakeholders and a co-design approach. The project team included a diverse representation of members from the PHC system including patient advisors, DMC team members, system leads, providers, Public Engagement team members and CFHI improvement coaches. Key outcomes of this 18-month long initiative included development of a working definition of patient and family engagement, development of a Patient and Family Engagement Resource Guide and evaluation of the resource guide. This novel initiative provided us an opportunity to develop a supportive system-wide implementation plan and a strategy to include PFAs in decision-making processes in PHC. The well-established co-design methodology further allowed us to

Since palliative RT is underutilized, further research is needed to assess whether family physician educational interventions improve palliative RT referrals. The current study suggests that studies could target family physicians already in practice, with educational interventions focusing on hemostatic and other less commonly known indications for palliative RT.

    The global pandemic of obesity has led to an increased risk for prediabetes and type-2 diabetes (T2D). The aims of the current project are: (1) to evaluate the effect of a 22-week family based intervention program, including supervised exercise, on insulin resistance syndrome (IRS) risk in children with a high risk of developing T2D and (2) to identify the profile of microRNA in circulating exosomes and in peripheral blood mononuclear cells in children with a high risk of developing T2D and its response to a multidisciplinary intervention program including exercise. A total of 84 children, aged 8-12 years, with a high risk of T2D will be included and randomly assigned to control (N = 42) or intervention (N = 42) groups. The control group will receive a family based lifestyle education and psycho-educational program (2 days/month), while the intervention group will attend the same lifestyle education and psycho-educational program plus the exercise program (3 days/week, 90 min per session including warm-up, moderate to vigorous aerobic activities, and strength exercises). The following measurements will be evaluated at baseline prior to randomization and after the intervention: fasting insulin, glucose and hemoglobin A1c; body composition (dual-energy X-ray absorptiometry); ectopic fat (magnetic resonance imaging); microRNA expression in circulating exosomes and in peripheral blood mononuclear cells (MiSeq; Illumina); cardiorespiratory fitness (cardiopulmonary exercise testing); dietary habits and physical activity (accelerometry). Prevention and identification of children with a high risk of developing T2D could help to improve their cardiovascular health and to reduce the comorbidities associated with obesity.

The majority of FPs correctly identified that painful bone metastases (91%), airway obstruction (77%), painful local disease (85%), brain metastases (76%) and spinal cord compression (79%) can be effectively treated with RT, though few were aware that hemoptysis (42%) and hematuria (31%) can be effectively treated. There was a linear relationship between increasing involvement in palliative care and both self-assessed (p < 0.001) and tested (p = 0.02) knowledge. FPs had higher mean knowledge scores if they received post-MD training in palliative care (12% higher; p < 0.001) or radiotherapy (15% higher; p = 0.002). There was a strong relationship between FPs referral for palliative radiotherapy and both self-assessed knowledge (p < 0.001) and tested knowledge (p = 0.01). Self-assessed and tested knowledge of palliative RT is positively associated with referral for palliative RT. Since palliative RT is underutilized, further research is needed to assess whether family physician educational interventions improve palliative RT referrals.

    Children with life limiting conditions and their families have complex needs. Evaluations must consider their views and perspectives to ensure care is relevant, appropriate and acceptable. We consulted with children, young people, their parents and local professionals to gain a more informed picture of issues affecting them prior to preparing a bid to evaluate services in the area. Multiple methods included focus groups, face-to-face and telephone interviews and participatory activities. Recordings and products from activities were analysed for content to identify areas of relevance and concern. An overarching theme from parents was ‘Why does it happen like this?’ Services did not seem designed to meet their needs. Whilst children and young people expressed ideas related to quality of environment, services and social life, professionals focused on ways of meeting the families’ needs. The theme that linked families’ concerns with those of professionals was ‘assessing individual needs’. Two questions to be addressed by the evaluation are (1) to what extent are services designed to meet the needs of children and families and (2) to what extent are children, young people and their families consulted about what they need? Consultations with families and service providers encouraged us to continue their involvement as partners in the evaluation. PMID:24270996

    Nance-Horan Syndrome (NHS) or X-linked cataract-dental syndrome is a disease of unknown gene action mechanism, characterized by congenital cataract, dental anomalies, dysmorphic features and, in some cases, mental retardation. We performed linkage analysis in a Tunisian family with NHS in which affected males and obligate carrier female share a common haplotype in the Xp22.32-p11.21 region that contains the NHS gene. Direct sequencing of NHS coding exons and flanking intronic sequences allowed us to identify the first missense mutation (P551S) and a reported SNP-polymorphism (L1319F) in exon 6, a reported UTR-SNP (c.7422 C>T) and a novel one (c.8239 T>A) in exon 8. Both variations P551S and c.8239 T>A segregate with NHS phenotype in this family. Although truncations, frame-shift and copy number variants have been reported in this gene, no missense mutations have been found to segregate previously. This is the first report of a missense NHS mutation causing NHS phenotype (including cardiac defects). We hypothesize also that the non-reported UTR-SNP of the exon 8 (3'-UTR) is specific to the Tunisian population.

    A thorough characterization of the genetic diversity of viruses present in vector and vertebrate host populations is essential for the early detection of and response to emerging pathogenic viruses, yet genetic characterization of many important viral groups remains incomplete. The Simbu serogroup of the genus Orthobunyavirus, family Bunyaviridae, is an example. The Simbu serogroup currently consists of a highly diverse group of related arboviruses that infect both humans and economically important livestock species. Here, we report complete genome sequences for 11 viruses within this group, with a focus on the large and poorly characterized Manzanilla and Oropouche species complexes. Phylogenetic and pairwise divergence analyses indicated the presence of high levels of genetic diversity within these two species complexes, on a par with that seen among the five other species complexes in the Simbu serogroup. Based on previously reported divergence thresholds between species, the data suggested that these two complexes should actually be divided into at least five species. Together these five species formed a distinct phylogenetic clade apart from the rest of the Simbu serogroup. Pairwise sequence divergences among viruses of this clade and viruses in other Simbu serogroup species complexes were similar to levels of divergence among the other orthobunyavirus serogroups. The genetic data also suggested relatively high levels of natural reassortment, with three potential reassortment events present, including two well-supported events involving viruses known to infect humans.

    Rhizobial Nod factors are key symbiotic signals responsible for starting the nodulation process in host legume plants. Of the six Medicago truncatula genes controlling a Nod factor signaling pathway, Nod Factor Perception (NFP) was reported as a candidate Nod factor receptor gene. Here, we provide further evidence for this by showing that NFP is a lysin [corrected] motif (LysM)-receptor-like kinase (RLK). NFP was shown both to be expressed in association with infection thread development and to be involved in the infection process. Consistent with deviations from conserved kinase domain sequences, NFP did not show autophosphorylation activity, suggesting that NFP needs to associate with an active kinase or has unusual functional characteristics different from classical kinases. Identification of nine new M. truncatula LysM-RLK genes revealed a larger family than in the nonlegumes Arabidopsis (Arabidopsis thaliana) or rice (Oryza sativa) of at least 17 members that can be divided into three subfamilies. Three LysM domains could be structurally predicted for all M. truncatula LysM-RLK proteins, whereas one subfamily, which includes NFP, was characterized by deviations from conserved kinase sequences. Most of the newly identified genes were found to be expressed in roots and nodules, suggesting this class of receptors may be more extensively involved in nodulation than was previously known.

    Necrosis- and ethylene-inducing-like proteins (NLP) are widely distributed in eukaryotic and prokaryotic plant pathogens and are considered to be important virulence factors. We identified, in total, 70 potential Phytophthora sojae NLP genes but 37 were designated as pseudogenes. Sequence alignment of the remaining 33 NLP delineated six groups. Three of these groups include proteins with an intact heptapeptide (Gly-His-Arg-His-Asp-Trp-Glu) motif, which is important for necrosis-inducing activity, whereas the motif is not conserved in the other groups. In total, 19 representative NLP genes were assessed for necrosis-inducing activity by heterologous expression in Nicotiana benthamiana. Surprisingly, only eight genes triggered cell death. The expression of the NLP genes in P. sojae was examined, distinguishing 20 expressed and 13 nonexpressed NLP genes. Real-time reverse-transcriptase polymerase chain reaction results indicate that most NLP are highly expressed during cyst germination and infection stages. Amino acid substitution ratios (Ka/Ks) of 33 NLP sequences from four different P. sojae strains resulted in identification of positive selection sites in a distinct NLP group. Overall, our study indicates that expansion and pseudogenization of the P. sojae NLP family results from an ongoing birth-and-death process, and that varying patterns of expression, necrosis-inducing activity, and positive selection suggest that NLP have diversified in function.

    Thirty-seven families with four or more cases of breast cancer or breast and ovarian cancer were analyzed for mutations in BRCA1. Twelve different germ-line mutations, four novel and eight previously observed, were detected in 16 families. Five families of Ashkenazi Jewish descent carried the 185delAG mutation and shared the same haplotype at eight polymorphic markers spanning {approximately}850 kb at BRCA1. Expressivity of 185delAG in these families varied, from early-onset bilateral breast cancer and ovarian cancer to late-onset breast cancer without ovarian cancer. Mutation 4184delTCAA occurred independently in two families. In one family, penetrance was complete, with females developing early-onset breast cancer or ovarian cancer and the male carrier developing prostatic cancer, whereas, in the other family, penetrance was incomplete and only breast cancer occurred, diagnosed at ages 38-81 years. Two novel nonsense mutations led to the loss of mutant BRCA1 transcript in families with 10 and 6 cases of early-onset breast cancer and ovarian cancer. A 665-nt segment of the BRCA1 3{prime}-UTR and 1.3 kb of genomic sequence including the putative promoter region were invariant by single-strand conformation analysis in 13 families without coding-sequence mutations. Overall in our series, BRCA1 mutations have been detected in 26 families: 16 with positive BRCA1 lod scores, 7 with negative lod scores (reflecting multiple sporadic breast cancers), and 3 not tested for linkage. Three other families have positive lod scores for linkage to BRCA2, but 13 families without detected BRCA1 mutations have negative lod scores for both BRCA1 and BRCA2. 57 refs., 5 figs., 3 tabs.

    The family Chlamydiaceae (order Chlamydiales, phylum Chlamydiae) comprises important, obligate intracellular bacterial pathogens of humans and animals. Subdivision of the family into the two genera Chlamydia and Chlamydophila has been discussed controversially during the past decade. Here, we have revisited the current classification in the light of recent genomic data and in the context of the unique biological properties of these microorganisms. We conclude that neither generally used 16S rRNA sequence identity cut-off values nor parameters based on genomic similarity consistently separate the two genera. Notably, no easily recognizable phenotype such as host preference or tissue tropism is available that would support a subdivision. In addition, the genus Chlamydophila is currently not well accepted and not used by a majority of research groups in the field. Therefore, we propose the classification of all 11 currently recognized Chlamydiaceae species in a single genus, the genus Chlamydia. Finally, we provide emended descriptions of the family Chlamydiaceae, the genus Chlamydia, as well as the species Chlamydia abortus, Chlamydia caviae and Chlamydia felis.

    People who have experienced illness due to significant disease, multimorbidity and/or advanced age are high utilizers of the health care system. Yet this population has had little formal opportunity to participate in guiding the health care research agenda, and few mechanisms exist for researchers to engage this population in an efficient way. We describe the process of developing a standing patient and family advisory panel to incorporate this population's voice into research in the USA. The panel was created at the University of Colorado. Preliminary panel development consisted of a needs assessment, information gathering and participant recruitment. We collected feedback from researchers who consulted with the panel and from panel members in order to better understand the experience from the patient and family member perspective. The patient and family research advisory panel consists of eight advisors who have experience with significant disease, multimorbidity and/or advanced age, two physicians and a program manager. The panel meets every other month for 2 hours with the main purpose of advising diverse researchers on health care studies. People with significant disease, multimorbidity and/or advanced age represent a growing demographic in the USA, and their engagement in research is essential as the model of health care delivery moves from volume to value. © The Author 2017.

    The taxonomic position of the marine genera Alteromonas, Pseudoalteromonas, Idiomarina, and Colwellia within the gamma subclass of the class Proteobacteria were specified on the basis of their phenotypic, genotypic, and phylogenetic characteristics. Gram-negative aerobic bacteria of the genera Alteromonas, Pseudoalteromonas, and Idiomarina and facultatively anaerobic bacteria of the genus Colwellia were found to form a phylogenetic cluster with a 16S rRNA sequence homology of 90% or higher. The characteristics of these genera presented in this paper allow their reliable taxonomic identification. Based on the analysis of our experimental data and analyses available in the literature, we propose to combine the genera Alteromonas, Pseudoalteromonas, Idiomarina, and Colwellia into a new family, Alteromonadaceae fam. nov., with the type genus Alteromonas.

    Moving beyond simply documenting that political violence negatively impacts children, we tested a social-ecological hypothesis for relations between political violence and child outcomes. Participants were 700 mother-child (M = 12.1 years, SD = 1.8) dyads from 18 working-class, socially deprived areas in Belfast, Northern Ireland, including single- and two-parent families. Sectarian community violence was associated with elevated family conflict and children's reduced security about multiple aspects of their social environment (i.e., family, parent-child relations, and community), with links to child adjustment problems and reductions in prosocial behavior. By comparison, and consistent with expectations, links with negative family processes, child regulatory problems, and child outcomes were less consistent for nonsectarian community violence. Support was found for a social-ecological model for relations between political violence and child outcomes among both single- and two-parent families, with evidence that emotional security and adjustment problems were more negatively affected in single-parent families. The implications for understanding social ecologies of political violence and children's functioning are discussed.

    Antroquinonol is isolated from Antrodia camphorata , a camphor tree mushroom, and is a valuable traditional Chinese herbal medicine that exhibits pharmacological activities against several diseases, including cancer. This first-in-human phase I study of antroquinonol included patients with metastatic non-small-cell lung cancer who had received at least two prior systemic treatment regimens. An open-label, dose escalation, pharmacokinetic (PK) study was conducted to determine the maximum tolerable dose (MTD), dose-limiting toxicities (DLTs), and safety/tolerability and preliminary efficacy profiles of antroquinonol. The patients received escalating doses of once-daily antroquinonol in 4-week cycles (up to 3 cycles). The escalated doses were 50-600 mg. PKs were evaluated on day 1 and 28 of cycle 1. Between January, 2011 and October, 2012, 13 patients with metastatic adenocarcinoma were enrolled. No DLTs occurred in any patient at any dose level. T max was observed between 1.00 and 3.70 h under single-dose conditions, and at 1.92-4.05 h under multiple-dose conditions. The mean elimination half-life ranged between 1.30 and 4.33 h, independent of the treatment dose. Antroquinonol at all dose levels had a mild toxicity profile, with no reported treatment-related mortality. The most common treatment-related adverse events were diarrhea, vomiting and nausea. The best tumor response was stable disease in 3 patients. In conclusion, antroquinonol at all dose levels, administered daily for 4 weeks, was generally safe and well tolerated, without DLTs. The recommended dose level for a phase II study is ≥600 mg daily.

    Homeless families in transitional housing face a number of distinct challenges, yet there is little research seeking to guide prevention and intervention work with homeless parents. Informed by the tenets of community-based participatory research, the purpose of this study was to identify relevant components to include in a parenting intervention for this population. Data were gathered from 40 homeless parents through semistructured individual interviews and were analyzed using qualitative content analysis. The resulting 15 categories suggest several topics, approach considerations, and activities that can inform parenting intervention work with homeless families in transitional housing. Study findings are discussed within the context of intervention fidelity versus adaptation, and implications for practice, research, and policy are suggested. This study provides important insights for informing parenting intervention adaptation and implementation efforts with homeless families in transitional housing.

    Notably absent from the intervention literature are parent training programs targeting school-aged children with autism who have limited communication skills (Tager-Flusberg and Kasari in Autism Res 6:468-478, 2013). Sixty-one children with autism age 5-8 with minimal spontaneous communication received a 6-month social communication intervention including parent training. Parent-child play interactions were coded for parents' strategy implementation and children's time jointly engaged (Adamson et al. in J Autism Dev Disord 39:84-96, 2009). Parents mastered an average of 70% of the strategies. Further analyses indicated some gains in implementation occurred from mere observation of sessions, while the greatest gains occurred in the first month of active coaching and workshops. Children's joint engagement was associated with parents' implementation success across time demonstrating parents' implementation was relevant to children's social engagement.

    The National Family Health Survey (NFHS)-3 clearly delineates that the usage of contraceptive practices has increased considerably but is more inclined toward terminal methods of contraception especially the female sterilization. The fact is also evident from various studies carried out from time to time in different Indian states. Given the context we carried out a short review to understand the family planning practices, programs and policies in India including implants and injectable contraceptives with a special focus on the state of Jharkhand. We found that among the reversible methods IUCD (intra uterine contraceptive devices), OC (oral contraceptive) pills and condoms are the most commonly used methods. In this review, in addition to national picture, we specially focused on the state of Jharkhand owing to its very gloomy picture of family planning practices as per NFHS -3 reports. The current usage of any methods of contraception in Jharkhand is only 35.7% out of which terminal methods especially female sterilization accounts to 23.4% and male sterilization being only 0.4%. Similar picture is also reflected in the conventional methods such as; IUCD-0.6%, oral pill -3.8% and condom-2.7%. Compared to the national figure the unmet need for family planning in Jharkhand is also relatively high for the conventional reversible methods than that of terminal methods which is 11.9 and 11.3 respectively. Injectable contraceptives are available only through private or social marketing channels, because of which their use is limited. The studies carried out in different Indian states show improvement in contraceptive prevalence but the same needs further improvement.

    The plant GT43 protein family includes xylosyltransferases that are known to be required for xylan backbone biosynthesis, but have incompletely understood specificities. RT-qPCR and histochemical (GUS) analyses of expression patterns of GT43 members in hybrid aspen, reported here, revealed that three clades of the family have markedly differing specificity towards secondary wall-forming cells (wood and extraxylary fibres). Intriguingly, GT43A and B genes (corresponding to the Arabidopsis IRX9 clade) showed higher specificity for secondary-walled cells than GT43C and D genes (IRX14 clade), although both IRX9 and IRX14 are required for xylosyltransferase activity. The remaining genes, GT43E, F and G (IRX9-L clade), showed broad expression patterns. Transient transactivation analyses of GT43A and B reporters demonstrated that they are activated by PtxtMYB021 and PNAC085 (master secondary wall switches), mediated in PtxtMYB021 activation by an AC element. The high observed secondary cell wall specificity of GT43B expression prompted tests of the efficiency of its promoter (pGT43B), relative to the CaMV 35S (35S) promoter, for overexpressing a xylan acetyl esterase (CE5) or downregulating REDUCED WALL ACETYLATION (RWA) family genes and thus engineering wood acetylation. CE5 expression was weaker when driven by pGT43B, but it reduced wood acetyl content substantially more efficiently than the 35S promoter. RNAi silencing of the RWA family, which was ineffective using 35S, was achieved when using GT43B promoter. These results show the utility of the GT43B promoter for genetically engineering properties of wood and fibres. © 2014 Society for Experimental Biology, Association of Applied Biologists and John Wiley & Sons Ltd.

    The extent of acceptance of contraceptive methods still varies within societies. Reliance on sterilisation is appearing earlier in marriage and among ever-younger ages and lower parities. To study the family planning practices adopted by women who undergo tubectomy before the acceptance of tubectomy. Cross-sectional study of tubectomy acceptors who attended a corporation referral maternity home in Bangalore, India by interview method using a pre-designed a pre-tested structured questionnaire. Majority 295(73.9%) of the study subjects had not practised any method of contraception before they underwent sterilisation. Increase in the education levels of the study subjects was associated with an increase in the contraceptive use (temporary methods) before they accepted tubectomy; this association was found to be statistically significant (p<0.0001).

    All patients with port wine stains (PWS) attending a tunable dye laser clinic were examined by one author (SWL), forming a large group which has allowed study of the demographic data of such patients. Two hundred and eighty-three patients, 217 females (median age 24 years, range 0.5-73) and 66 males (median age 20 years, range 0.75-72), were examined. The PWS were on the face in 226, neck in 69, trunk in 36, upper limb in 35 and lower limb in 29. The commonest lesional colour was purple (63 patients), while 39 naevi were pink/red, 35 pink/ purple and 35 pink. The naevus was flat in 255 patients, cobblestoned in 28, associated with hypertrophy in 31 and with scarring in 22. Seventy-two patients (25.4%) had a positive family history of birthmarks, 20 strawberry haemangiomas and 22 PWS, the family history of PWS being higher than expected for the prevalence of this naevus in the population. One hundred and forty-six patients were also examined for naevus anaemicus which was noted in 12 (8.2%), confirming an association between these two naevi. Ninety-four patients had received previous treatment, most commonly with the argon laser (56 patients), of whom only five reported a good result, and 17 of 22 patients with treatment-related scarring had been treated with this laser. Cosmetic camouflage was used in 109 (38.5%) of patients, who usually had PWS on the face (94%), of whom only 46 (16%) had received advice of its use.

  20. Prior data for non-normal priors.

    Data augmentation priors facilitate contextual evaluation of prior distributions and the generation of Bayesian outputs from frequentist software. Previous papers have presented approximate Bayesian methods using 2x2 tables of 'prior data' to represent lognormal relative-risk priors in stratified and regression analyses. The present paper describes extensions that use the tables to represent generalized-F prior distributions for relative risks, which subsume lognormal priors as a limiting case. The method provides a means to increase tail-weight or skew the prior distribution for the log relative risk away from normality, while retaining the simple 2x2 table form of the prior data. When prior normality is preferred, it also provides a more accurate lognormal relative-risk prior in for the 2x2 table format. For more compact representation in regression analyses, the prior data can be compressed into a single data record. The method is illustrated with historical data from a study of electronic foetal monitoring and neonatal death.

  1. Identification of a rare 17p13.3 duplication including the BHLHA9 and YWHAE genes in a family with developmental delay and behavioural problems

    Full Text Available Abstract Background Deletions and duplications of the PAFAH1B1 and YWHAE genes in 17p13.3 are associated with different clinical phenotypes. In particular, deletion of PAFAH1B1 causes isolated lissencephaly while deletions involving both PAFAH1B1 and YWHAE cause Miller-Dieker syndrome. Isolated duplications of PAFAH1B1 have been associated with mild developmental delay and hypotonia, while isolated duplications of YWHAE have been associated with autism. In particular, different dysmorphic features associated with PAFAH1B1 or YWHAE duplication have suggested the need to classify the patient clinical features in two groups according to which gene is involved in the chromosomal duplication. Methods We analyze the proband and his family by classical cytogenetic and array-CGH analyses. The putative rearrangement was confirmed by fluorescence in situ hybridization. Results We have identified a family segregating a 17p13.3 duplication extending 329.5 kilobases by FISH and array-CGH involving the YWHAE gene, but not PAFAH1B1, affected by a mild dysmorphic phenotype with associated autism and mental retardation. We propose that BHLHA9, YWHAE, and CRK genes contribute to the phenotype of our patient. The small chromosomal duplication was inherited from his mother who was affected by a bipolar and borderline disorder and was alcohol addicted. Conclusions We report an additional familial case of small 17p13.3 chromosomal duplication including only BHLHA9, YWHAE, and CRK genes. Our observation and further cases with similar microduplications are expected to be diagnosed, and will help better characterise the clinical spectrum of phenotypes associated with 17p13.3 microduplications.

    Combination therapy of simeprevir (SIM)/sofosbuvir (SOF) is an approved treatment for hepatitis C genotype (gen) 1 with overall SVR12 rate of 85%-95%. The single tablet fixed-dose combination of ledipasvir (LDV)/SOF is also approved for gen 1 with sustained virologic response at 12 weeks (SVR12) rates ≥95%. No data are available on the efficacy of retreatment with LDV/SOF in patients who failed initial treatment with SIM/SOF. Our aim was to evaluate the efficacy of retreatment with LDV/SOF ± ribavirin (RBV) in gen 1 patients who had previously failed treatment with SIM/SOF. Data from a combined treatment cohort of 2 hepatology centres, which included patients previously treated with SIM/SOF ± RBV for 12 weeks but failed to achieve SVR and then underwent retreatment with LDV/SOF ± RBV, were analysed (n = 30). LDV/SOF ± RBV was administered for 12-24 weeks based on the discretion of the treating hepatologist. Of the 30 patients, 23 (77%) were male, 77% were Caucasian and 26 (87%) were gen 1a. 26 (86%) had cirrhosis, of which 16 (62%) had decompensated, Child's class B or C cirrhosis. Three patients were liver transplant recipients with recurrent hepatitis C. Overall, 27/30 (90%) achieved SVR. Treatment was well tolerated with 37% reporting no adverse events. The most common adverse events were fatigue, headache, insomnia and nausea. Two patients with Child's B cirrhosis required hospitalization during treatment for variceal haemorrhage and abdominal pain respectively. However, no treatment discontinuations or deaths occurred. Single tablet fixed-dose combination LDV/SOF ± RBV is efficacious and well tolerated in patients who previously failed treatment with SIM/SOF, including those with decompensated cirrhosis and recurrent hepatitis C following liver transplantation. © 2018 John Wiley & Sons Ltd.

    Rhizobial Nod factors are key symbiotic signals responsible for starting the nodulation process in host legume plants. Of the six Medicago truncatula genes controlling a Nod factor signaling pathway, Nod Factor Perception (NFP) was reported as a candidate Nod factor receptor gene. Here, we provide further evidence for this by showing that NFP is a lysine motif (LysM)-receptor-like kinase (RLK). NFP was shown both to be expressed in association with infection thread development and to be involved in the infection process. Consistent with deviations from conserved kinase domain sequences, NFP did not show autophosphorylation activity, suggesting that NFP needs to associate with an active kinase or has unusual functional characteristics different from classical kinases. Identification of nine new M. truncatula LysM-RLK genes revealed a larger family than in the nonlegumes Arabidopsis (Arabidopsis thaliana) or rice (Oryza sativa) of at least 17 members that can be divided into three subfamilies. Three LysM domains could be structurally predicted for all M. truncatula LysM-RLK proteins, whereas one subfamily, which includes NFP, was characterized by deviations from conserved kinase sequences. Most of the newly identified genes were found to be expressed in roots and nodules, suggesting this class of receptors may be more extensively involved in nodulation than was previously known.

    A polypeptide was identified in the venom of the scorpion Leiurus quinquestriatus hebraeus by its potency to inhibit the high affinity binding of the radiolabeled snake venom toxin dendrotoxin I ({sup 125}I-DTX{sub I}) to its receptor site. It has been purified, and its properties investigated by different techniques were found to be similar to those of MCD and DTX{sub I}, two polypeptide toxins active on a voltage-dependent K{sup +} channel. However, its amino acid sequence was determined, and it was shown that this toxin is in fact charybdotoxin (ChTX), a toxin classically used as a specific tool to block one class of Ca{sup 2+}-activated K{sup +} channels. ChTX, DTX{sub I}, and MCD are potent convulsants and are highly toxic when injected intracerebroventricularly in mice. Their toxicities correlate well with their affinities for their receptors in rat brain. These three structurally different toxins release ({sup 3}H)GABA from preloaded synaptosomes, the efficiency order being DTX{sub I} > ChTX > MCD. Both binding and cross-linking experiments of ChTX to rat brain membranes and to the purified MCD/DTX{sub I} binding protein have shown that the {alpha}-subunit of the MCD/DTX{sub I}-sensitive K{sup +} channel protein also contains the ChTX binding sites. Binding sites for DTX{sub I}, MCD, and ChTX are in negative allosteric interaction. The results show that charybdotoxin belongs to the family of toxins which already includes the dendrotoxins and MCD, which are blockers of voltage-sensitive K{sup +} channels. ChTX is clearly not selective for Ca{sup 2+}-activated K{sup +} channel.

    2017-04-01

    Full Text Available Longitudinal study provides a robust method for tracking developmental trajectories. Yet inherent problems of retesting pose challenges in distinguishing biological developmental change from prior testing experience. We examined factors potentially influencing change scores on 16 neuropsychological test composites over 1 year in 568 adolescents in the National Consortium on Alcohol and NeuroDevelopment in Adolescence (NCANDA project. The twice-minus-once-tested method revealed that performance gain was mainly attributable to testing experience (practice with little contribution from predicted developmental effects. Group mean practice slopes for 13 composites indicated that 60% to ∼100% variance was attributable to test experience; General Ability accuracy showed the least practice effect (29%. Lower baseline performance, especially in younger participants, was a strong predictor of greater gain. Contributions from age, sex, ethnicity, examination site, socioeconomic status, or family history of alcohol/substance abuse were nil to small, even where statistically significant. Recognizing that a substantial proportion of change in longitudinal testing, even over 1-year, is attributable to testing experience indicates caution against assuming that performance gain observed during periods of maturation necessarily reflects development. Estimates of testing experience, a form of learning, may be a relevant metric for detecting interim influences, such as alcohol use or traumatic episodes, on behavior.

  10. A Noninformative Prior on a Space of Distribution Functions

    Directory of Open Access Journals (Sweden)

    Alexander Terenin

    2017-07-01

    Full Text Available In a given problem, the Bayesian statistical paradigm requires the specification of a prior distribution that quantifies relevant information about the unknowns of main interest external to the data. In cases where little such information is available, the problem under study may possess an invariance under a transformation group that encodes a lack of information, leading to a unique prior—this idea was explored at length by E.T. Jaynes. Previous successful examples have included location-scale invariance under linear transformation, multiplicative invariance of the rate at which events in a counting process are observed, and the derivation of the Haldane prior for a Bernoulli success probability. In this paper we show that this method can be extended, by generalizing Jaynes, in two ways: (1 to yield families of approximately invariant priors; and (2 to the infinite-dimensional setting, yielding families of priors on spaces of distribution functions. Our results can be used to describe conditions under which a particular Dirichlet Process posterior arises from an optimal Bayesian analysis, in the sense that invariances in the prior and likelihood lead to one and only one posterior distribution.

    Fibroblast growth factors consist of receptor tyrosine kinase binding proteins involved in growth, differentiation, and regeneration of a variety of tissues of the head and neck. Their role in the development of teeth has been documented, and their presence in human odontogenic cysts and tumors has previously been investigated. Odontoma–dysphagia syndrome (OMIM 164330) is a very rare disorder characterized by clustering of teeth as compound odontoma, dysplasia and aplasia of teeth, slight craniofacial abnormalities, and dysphagia. We have followed the clinical course of the disease in a family over more than 30 years and have identified a genetic abnormality segregating with the disorder. We evaluated clinical data from nine different family members and obtained venous blood probes for genetic studies from three family members (two affected and one unaffected). The present family with five patients in two generations has remained one out of only two known cases with this very rare syndrome. All those affected showed teeth dysplasia, oligodontia, and dysplasia and odontoma of the upper and lower jaw. Additional signs included dysphagia and strictures of the oesophagus. Comorbidity in one patient included aortic stenosis and coronary artery disease, requiring coronary bypasses and aortic valve replacement. Genome-wide SNP array analyses in three family members (two affected and one unaffected) revealed a microduplication of chromosome 11q13.3 spanning 355 kilobases (kb) and including two genes in full length, fibroblast growth factors 3 (FGF3) and 4 (FGF4). The microduplication identified in this family represents the most likely cause of the odontoma–dysphagia syndrome and implies that the syndrome is caused by a gain of function of the FGF3 and FGF4 genes. Mutations of FGF receptor genes can cause craniofacial syndromes such as odontoma–dysphagia syndrome. Following this train of thought, an evaluation of FGF gene family in sporadic odontoma could be

    In the health field, technologies of care relations are in the scope of the worker-user encounter, implying intersubjectivity with the development of relationships between subjects, resulting in action. Evaluation studies synthesize knowledge produced on the consequences of using these technologies for society. This anthropological study aims to understand the perception of the elderly regarding the resolution capability and effectiveness of the acts produced in health care relationships in the context of the Family Health Strategy (ESF). The group studied consisted of 57 elderly residents in Bambui, State of Minas Gerais, Brazil. The model of signs, meanings and actions was used for collecting and analyzing data and the semi-structured interview was applied as a research technique. Elderly individuals assess resolution capability and effectiveness of the acts of care in the ESF as negative, with relation to the quality of user and professional interaction. The ESF is not effective and the desired change in the health care model has not occurred in practice. It repeats the centrality of the medical-drug-procedure model that treats the disease rather than the patient, perceiving old age as a disease and illness as being related to aging.

  16. Analysis of Corporal Punishment of Children in the Family based on the Semantic Reading of Traditional Islamic Narratives including the Word “Dharb” [Hitting

    Directory of Open Access Journals (Sweden)

    حمیدرضا بصیری

    2016-06-01

    Full Text Available There are various traditional Islamic narratives in relation to treating children. The common understanding of these narratives allows for the corporal punishment of children in the family, although some narratives forbid parents from such behavior. With reference to traditional Islamic texts, the word “hitting” (Arabic: dharb is the main and most frequently used word implying the permissibility of corporal punishment. An investigation of the use of the term “dharb” (Arabic: ضرب in the Quran, traditional Islamic narratives and the Arabic language reveals different instances of a general sense of “occurence” which can denote “doing or carrying out”. On this basis, a wide range of usages for this word in absolute terms (without preposition is conceivable with the meanings of protecting, financially supporting, guiding and nurturing children. It seems that limiting the meaning of dharb to corporal punishment in all traditional Islamic narratives without considering the other meanings has led to incorrect interpretations of such narratives.

  17. Rare CNVs in Suicide Attempt include Schizophrenia-Associated Loci and Neurodevelopmental Genes: A Pilot Genome-Wide and Family-Based Study.

    Directory of Open Access Journals (Sweden)

    Marcus Sokolowski

    Full Text Available Suicidal behavior (SB has a complex etiology involving genes and environment. One of the genetic components in SB could be copy number variations (CNVs, as CNVs are implicated in neurodevelopmental disorders. However, a recently published genome-wide and case-control study did not observe any significant role of CNVs in SB. Here we complemented these initial observations by instead using a family-based trio-sample that is robust to control biases, having severe suicide attempt (SA in offspring as main outcome (n = 660 trios. We first tested for CNV associations on the genome-wide Illumina 1M SNP-array by using FBAT-CNV methodology, which allows for evaluating CNVs without reliance on CNV calling algorithms, analogous to a common SNP-based GWAS. We observed association of certain T-cell receptor markers, but this likely reflected inter-individual variation in somatic rearrangements rather than association with SA outcome. Next, we used the PennCNV software to call 385 putative rare (100 kb CNVs, observed in n = 225 SA offspring.

    Suicidal behavior (SB) has a complex etiology involving genes and environment. One of the genetic components in SB could be copy number variations (CNVs), as CNVs are implicated in neurodevelopmental disorders. However, a recently published genome-wide and case-control study did not observe any significant role of CNVs in SB. Here we complemented these initial observations by instead using a family-based trio-sample that is robust to control biases, having severe suicide attempt (SA) in offspring as main outcome (n = 660 trios). We first tested for CNV associations on the genome-wide Illumina 1M SNP-array by using FBAT-CNV methodology, which allows for evaluating CNVs without reliance on CNV calling algorithms, analogous to a common SNP-based GWAS. We observed association of certain T-cell receptor markers, but this likely reflected inter-individual variation in somatic rearrangements rather than association with SA outcome. Next, we used the PennCNV software to call 385 putative rare (100 kb) CNVs, observed in n = 225 SA offspring. Nine SA offspring had rare CNV calls in a set of previously schizophrenia-associated loci, indicating the importance of such CNVs in certain SA subjects. Several additional, very large (>1MB) sized CNV calls in 15 other SA offspring also spanned pathogenic regions or other neural genes of interest. Overall, 45 SA had CNVs enriched for 65 medically relevant genes previously shown to be affected by CNVs, which were characterized by a neurodevelopmental biology. A neurodevelopmental implication was partly congruent with our previous SNP-based GWAS, but follow-up analysis here indicated that carriers of rare CNVs had a decreased burden of common SNP risk-alleles compared to non-carriers. In conclusion, while CNVs did not show genome-wide association by the FBAT-CNV methodology, our preliminary observations indicate rare pathogenic CNVs affecting neurodevelopmental functions in a subset of SA, who were distinct from SA having increased SNP

    Full Text Available Abstract Background Mutations in OTOF gene, encoding otoferlin, cause DFNB9 deafness and non-syndromic auditory neuropathy (AN. The aim of this study is to identify OTOF mutations in Chinese patients with non-syndromic auditory neuropathy. Methods 73 unrelated Chinese Han patients with AN, including one case of temperature sensitive non-syndromic auditory neuropathy (TS-NSRAN and 92 ethnicity-matched controls with normal hearing were screened. Forty-five pairs of PCR primers were designed to amplify all of the exons and their flanking regions of the OTOF gene. The PCR products were sequenced and analyzed for mutation identification. Results Five novel possibly pathogenic variants (c.1740delC, c.2975_2978delAG, c.1194T>A, c.1780G>A, c.4819C > T were identified in the group of 73 AN patients, in which two novel mutant alleles (c.2975_2978delAG + c.4819C > T were identified in one Chinese TS-NSRAN case. Besides, 10 non-pathogenic variants of the OTOF gene were found in AN patients and controls. Conclusions Screening revealed that mutations in the OTOF gene account for AN in 4 of 73(5.5% sporadic AN patients, which shows a lower genetic load of that gene in contrast to the previous studies based on other populations. Notably, we found two novel mutant alleles related to temperature sensitive non-syndromic auditory neuropathy. This mutation screening study further confirms that the OTOF gene contributes to ANs and to TS-NSRAN.

  1. Prior indigenous technological species

    One of the primary open questions of astrobiology is whether there is extant or extinct life elsewhere the solar system. Implicit in much of this work is that we are looking for microbial or, at best, unintelligent life, even though technological artefacts might be much easier to find. Search for Extraterrestrial Intelligence (SETI) work on searches for alien artefacts in the solar system typically presumes that such artefacts would be of extrasolar origin, even though life is known to have existed in the solar system, on Earth, for eons. But if a prior technological, perhaps spacefaring, species ever arose in the solar system, it might have produced artefacts or other technosignatures that have survived to present day, meaning solar system artefact SETI provides a potential path to resolving astrobiology's question. Here, I discuss the origins and possible locations for technosignatures of such a prior indigenous technological species, which might have arisen on ancient Earth or another body, such as a pre-greenhouse Venus or a wet Mars. In the case of Venus, the arrival of its global greenhouse and potential resurfacing might have erased all evidence of its existence on the Venusian surface. In the case of Earth, erosion and, ultimately, plate tectonics may have erased most such evidence if the species lived Gyr ago. Remaining indigenous technosignatures might be expected to be extremely old, limiting the places they might still be found to beneath the surfaces of Mars and the Moon, or in the outer solar system.

    This study corresponds to the second part of a companion paper devoted to the development of Bayesian multiple regression models accounting for randomness of genotypes in across population genome-wide prediction. This family of models considers heterogeneous and correlated marker effects and allelic frequencies across populations, and has the ability of considering records from non-genotyped individuals and individuals with missing genotypes in any subset of loci without the need for previous imputation, taking into account uncertainty about imputed genotypes. This paper extends this family of models by considering multivariate spike and slab conditional priors for marker allele substitution effects and contains derivations of approximate Bayes factors and fractional Bayes factors to compare models from part I and those developed here with their null versions. These null versions correspond to simpler models ignoring heterogeneity of populations, but still accounting for randomness of genotypes. For each marker loci, the spike component of priors corresponded to point mass at 0 in R S , where S is the number of populations, and the slab component was a S-variate Gaussian distribution, independent conditional priors were assumed. For the Gaussian components, covariance matrices were assumed to be either the same for all markers or different for each marker. For null models, the priors were simply univariate versions of these finite mixture distributions. Approximate algebraic expressions for Bayes factors and fractional Bayes factors were found using the Laplace approximation. Using the simulated datasets described in part I, these models were implemented and compared with models derived in part I using measures of predictive performance based on squared Pearson correlations, Deviance Information Criterion, Bayes factors, and fractional Bayes factors. The extensions presented here enlarge our family of genome-wide prediction models making it more flexible in the

    Full Text Available Methods are developed for eliciting a Dirichlet prior based upon stating bounds on the individual probabilities that hold with high prior probability. This approach to selecting a prior is applied to a contingency table problem where it is demonstrated how to assess the prior with respect to the bias it induces as well as how to check for prior-data conflict. It is shown that the assessment of a hypothesis via relative belief can easily take into account what it means for the falsity of the hypothesis to correspond to a difference of practical importance and provide evidence in favor of a hypothesis.

    This article examines the effectiveness of supportive housing in fostering family preservation and reunification for homeless families with multiple housing barriers. Results indicate that more thanhalfofthe supportive housing program families who are separated from their families by Child Protective Services prior to entering the program are reunified during the 12-month period after entering housing. The rate of reunification for supportive housing families is significantly higher than the rate for matched families who enter shelters, but not significantly different than the rate experienced by matched families entering public housing. This study provides encouraging evidence that housing for families in the child welfare system, including but necessarily limited to supportive housing, can facilitate the reunification of children.

    A fundamental premise of Bayesian methodology is that a priori information is accurately summarized by a single, precisely de ned prior distribution. In many cases, especially involving informative priors, this premise is false, and the (mis)application of Bayes methods produces posterior quantities whose apparent precisions are highly misleading. We examine the implications of uncertainty in prior distributions, and present graphical methods for dealing with them.

    Curriculum guidelines for health professionals in training recommend including health students in different levels of service in the Unified Health System (Sistema Único de Saúde - SUS). Thus, there is a need to investigate the perceptions of SUS users with regard to the students' participation. To evaluate the perceptions of SUS users about the participation of health students in Family Health Units (Unidades de Saúde da Família - USF). A total of 518 people were interviewed in the waiting room of eight USFs in São Carlos/São Paulo. The interviews were conducted by students using a semi-structured questionnaire, and the data were analyzed descriptively. A total of 391 (75.5%) women and 127 (24.5%) men, with a mean age of 42.0±17.5 years, were interviewed. Among these users, 33.1% had encountered students in the USF, mainly while receiving clinical care (52.1%) or during home visits (20.1%); 55.3% considered the student's performance very good, and 0.6% considered it very bad. Most of the interviewees (58.2%) evaluated the activity performed by the student as effective, whereas 8.2% considered it ineffective. The students were included primarily in individual assistance activities, and the care provided by the students was well accepted. Both the users' satisfaction scores and their reported expectations were positive.

    Phenotypic classification is problematic because small samples are ubiquitous; and, for these, use of prior knowledge is critical. If knowledge concerning the feature-label distribution - for instance, genetic pathways - is available, then it can be used in learning. Optimal Bayesian classification provides optimal classification under model uncertainty. It differs from classical Bayesian methods in which a classification model is assumed and prior distributions are placed on model parameters. With optimal Bayesian classification, uncertainty is treated directly on the feature-label distribution, which assures full utilization of prior knowledge and is guaranteed to outperform classical methods. The salient problem confronting optimal Bayesian classification is prior construction. In this paper, we propose a new prior construction methodology based on a general framework of constraints in the form of conditional probability statements. We call this prior the maximal knowledge-driven information prior (MKDIP). The new constraint framework is more flexible than our previous methods as it naturally handles the potential inconsistency in archived regulatory relationships and conditioning can be augmented by other knowledge, such as population statistics. We also extend the application of prior construction to a multinomial mixture model when labels are unknown, which often occurs in practice. The performance of the proposed methods is examined on two important pathway families, the mammalian cell-cycle and a set of p53-related pathways, and also on a publicly available gene expression dataset of non-small cell lung cancer when combined with the existing prior knowledge on relevant signaling pathways. The new proposed general prior construction framework extends the prior construction methodology to a more flexible framework that results in better inference when proper prior knowledge exists. Moreover, the extension of optimal Bayesian classification to multinomial

    Campomelic dysplasia and acampomelic campomelic dysplasia (ACD) are allelic disorders due to heterozygous mutations in or around SOX9. Translocations and deletions involving the SOX9 5' regulatory region are rare causes of these disorders, as well as Pierre Robin sequence (PRS) and 46,XY gonadal dysgenesis. Genotype-phenotype correlations are not straightforward due to the complex epigenetic regulation of SOX9 expression during development. We report a three-generation pedigree with a novel ∼1 Mb deletion upstream of SOX9 and including KCNJ2 and KCNJ16, and ascertained for dominant transmission of PRS. Further characterization of the family identified subtle appendicular anomalies and a variable constellation of axial skeletal features evocative of ACD in several members. Affected males showed learning disability. The identified deletion was smaller than all other chromosome rearrangements associated with ACD. Comparison with other reported translocations and deletions involving this region allowed further refining of genotype-phenotype correlations and an update of the smallest regions of overlap associated with the different phenotypes. Intrafamilial variability in this pedigree suggests a phenotypic continuity between ACD and PRS in patients carrying mutations in the SOX9 5' regulatory region. © 2015 Wiley Periodicals, Inc.

    Full Text Available We evaluated whether the comprehension of sentences that contained numerical information could benefit from presenting numbers in Arabic format and from using prior knowledge. Participants read sentences including numbers (Arabic digits or number words while the comprehension accuracy was evaluated. In addition, the sentences were biased or unbiased by people's prior knowledge about quantities. The results showed better comprehension for sentences that contained Arabic digits as compared to number words. Moreover, biased sentences were understood more accurately than unbiased sentences. These results indicate that information about magnitude in sentence context is comprehended better when quantities are presented in Arabic format and when they are associated with participants' world knowledge.

  13. Uninformative priors prefer simpler models

    Science.gov (United States)

    Mattingly, Henry; Abbott, Michael; Machta, Benjamin

    The Bayesian framework for model selection requires a prior for the probability of candidate models that is uninformative-it minimally biases predictions with preconceptions. For parameterized models, Jeffreys' uninformative prior, pJ, weights parameter space according to the local density of distinguishable model predictions. While pJ is rigorously justifiable in the limit that there is infinite data, it is ill-suited to effective theories and sloppy models. In these models, parameters are very poorly constrained by available data, and even the number of parameters is often arbitrary. We use a principled definition of `uninformative' as the mutual information between parameters and their expected data and study the properties of the prior p* which maximizes it. When data is abundant, p* approaches Jeffreys' prior. With finite data, however, p* is discrete, putting weight on a finite number of atoms in parameter space. In addition, when data is scarce, the prior lies on model boundaries, which in many cases correspond to interpretable models but with fewer parameters. As more data becomes available, the prior puts weight on models with more parameters. Thus, p* quantifies the intuition that better data can justify the use of more complex models.

    To describe the interconception challenges of women who had prior preterm births. We used a cross-sectional design and collected data via survey. King County, Washington. Ninety-two women who had prior early preterm births (20-33 weeks gestation) were included. Women were recruited from a larger study focused on exploring the infectious pathways for early preterm birth. Participants were interviewed once using open-ended and close-ended surveys. The primary open-ended survey question was What are the five greatest challenges you experience now? We analyzed data using inductive and summative content analysis and descriptive statistics. Ninety-one participants described challenges. One participant had no challenge. We categorized 11 challenges during the interconception period: Mothering (n = 70, 76%), Self-Care Desires (n = 35, 38%), Finances (n = 31, 34%), Employment (n = 31, 34%), Partner Relationships (n = 29, 32%), Individualized Concerns (n = 25, 27%), Mental Health (n = 23, 25%), Balance (n = 22, 24%), Physical Health (n = 19, 21%), Housing (n = 18, 20%), and Family (n = 17, 19%). Participants described an array of challenges that often related to their roles as mothers, employees, and partners. Our research advances knowledge by describing contemporary challenges of women during the interconception period.

    Steganography is the hiding of secret information within innocent-looking information (e.g., text, audio, image, video, etc.). A quantum version of steganography is a method based on quantum physics. In this paper, we propose quantum steganography by combining quantum error-correcting codes with prior entanglement. In many steganographic techniques, embedding secret messages in error-correcting codes may cause damage to them if the embedded part is corrupted. However, our proposed steganography can separately create secret messages and the content of cover messages. The intrinsic form of the cover message does not have to be modified for embedding secret messages. - Highlights: • Our steganography combines quantum error-correcting codes with prior entanglement. • Our steganography can separately create secret messages and the content of cover messages. • Errors in cover messages do not have affect the recovery of secret messages. • We embed a secret message in the Steane code as an example of our steganography.

    Full Text Available Though Bayesian methods are being used more frequently, many still struggle with the best method for setting priors with novel measures or task environments. We propose a method for setting priors by eliciting continuous probability distributions from naive participants. This allows us to include any relevant information participants have for a given effect. Even when prior means are near-zero, this method provides a principle way to estimate dispersion and produce shrinkage, reducing the occurrence of overestimated effect sizes. We demonstrate this method with a number of published studies and compare the effect of different prior estimation and aggregation methods.

    For the problem of image registration, the top few reliable correspondences are often relatively easy to obtain, while the overall matching accuracy may fall drastically as the desired correspondence number increases. In this paper, we present an efficient feature matching algorithm to employ sparse reliable correspondence priors for piloting the feature matching process. First, the feature geometric relationship within individual image is encoded as a spatial graph, and the pairwise feature similarity is expressed as a bipartite similarity graph between two feature sets; then the geometric neighborhood of the pairwise assignment is represented by a categorical product graph, along which the reliable correspondences are propagated; and finally a closed-form solution for feature matching is deduced by ensuring the feature geometric coherency as well as pairwise feature agreements. Furthermore, our algorithm is naturally applicable for incorporating manual correspondence priors for semi-supervised feature matching. Extensive experiments on both toy examples and real-world applications demonstrate the superiority of our algorithm over the state-of-the-art feature matching techniques.

    Prior research has documented caregiving difficulties in families of children with autism spectrum disorder (ASD). However, Latino families may encounter unique challenges. The purpose of this study was to understand the caregiving experiences of Latino families with children with ASD, including daily activities, coping strategies, and service utilization. Fifteen Latino parents of children with ASD were interviewed. The interviews were transcribed for analysis to identify themes of experiences unique to this population. Latino families of children with ASD encounter many similar issues as non-Latino families but also unique issues that affect service utilization. Four themes were identified: dealing with the diagnosis, dealing with stigma and isolation from family and community, understanding the role of mothers in changing family routines, and utilizing services. To meet the unique needs of Latino families, services need to be provided in culturally sensitive context that address children's needs within family units.

    Identifying eating and lifestyle behaviors prior to bariatric surgery may assist in better selecting and preparing patients and might lead to improved success rate. The current study aimed to assess eating behaviors and lifestyle trends among laparoscopic sleeve gastrectomy (LSG) candidates and to compare those trends between genders. This descriptive study was conducted in the bariatric clinic at the Haifa Assuta Medical Center. Data was gathered from medical records of LSG candidates that were evaluated before surgery in our institution between 2008 and 2011. The data included demographics, comorbidities, anthropometrics, weight management history, and lifestyle parameters. Eating pattern and eating habits were determined by eating habits questionnaires. A total of 266 LSG surgery candidates (71.4 % female) with an average age of 40.7 ± 10.9 years and pre-surgery BMI of 42.4 ± 4.8 kg/m 2 were studied. More than half of the patients have family history of obesity and their onset of obesity was before the age of 18 years (54.5 and 57.9 %, respectively). Most of the patients reported on poor eating habits and sedentary lifestyle: 65.1 % do not eat regular meals, 70.3 % skip over breakfast, 61.9 % presented loss of control eating, 45 % frequently consume sweets, and 80.1 % were classified as none active. There were no differences in eating patterns or lifestyle parameters between genders. High occurrence of unhealthy eating habits and a non-active lifestyle were detected in morbid obese candidates for LSG surgery. More efforts should be directed towards nutritional and lifestyle education prior to the surgery.

The aetiology of familial TGA is unknown. A pathophysiological mechanism akin to that in migraine attacks, comorbidity reported in a number of the examples of familial TGA, is one possibility. The study of familial TGA cases might facilitate the understanding of TGA aetiology.

    Full Text Available This study investigates the relationship between prior knowledge and reading comprehension in second language among postgraduate students in UPM. Participants in the study were 20 students who have the same level in English as a second language from several faculties. On the basis of a prior-knowledge questionnaire and test, students were selected; they were asked to sit a two-passage reading comprehension exam. According to the questionnaire and the short prior quiz, students had high prior knowledge in one of the two passages, and low prior knowledge in the other. The result showed significantly high relationship between the high prior knowledge and reading comprehension. However, the results showed significantly low relationship between low prior knowledge and reading comprehension. Yet the performance of students in a reading comprehension with high prior knowledge was significantly better than reading comprehension with low prior knowledge.

  12. Nutrient deficiencies prior to bariatric surgery.

    Roust, Lori R; DiBaise, John K

    2017-03-01

    The purpose of this review is to provide an update of recent additions to our understanding of the prevalence of nutrient deficiencies and the potential role of preoperative weight loss in contributing to these deficiencies in obese individuals planning to undergo bariatric surgery. Recent reports that have included bariatric surgery candidates from sites around the world have shown consistent deficiencies in a variety of nutrients. Although protein-energy malnutrition is uncommon preoperatively, micronutrient deficiencies occur commonly with multiple deficiencies often present in the same individual. No difference in the prevalence of deficiency between men and women is apparent, and a standard profile of susceptibility to deficiency has not been identified. In the only studies that have evaluated dietary intake of total energy, macronutrients and micronutrients preoperatively, despite an excess of calories ingested, micronutrient intake tends to be lower than recommended. A high prevalence of micronutrient deficiencies, especially vitamin D, folate, B12 and iron, is present in obese individuals being considered for bariatric surgery. Despite high-caloric intake, the deficiencies present appear to be related to the poor quality of the diet and low micronutrient intake. These findings strengthen prior recommendations of routine preoperative nutritional screening. Because a standard profile of susceptibility to deficiency has not been identified, extensive nutritional screening, including micronutrient testing, should be considered in all patients in the preoperative setting. Finally, we recommend early supplementation of vitamins and minerals based on laboratory assessment and incorporation of a program to optimize eating behaviors prior to surgery.

  17. Gamma prior distribution selection for Bayesian analysis of failure rate and reliability

    International Nuclear Information System (INIS)

    Waler, R.A.; Johnson, M.M.; Waterman, M.S.; Martz, H.F. Jr.

    1977-01-01

    It is assumed that the phenomenon under study is such that the time-to-failure may be modeled by an exponential distribution with failure-rate parameter, lambda. For Bayesian analyses of the assumed model, the family of gamma distributions provides conjugate prior models for lambda. Thus, an experimenter needs to select a particular gamma model to conduct a Bayesian reliability analysis. The purpose of this paper is to present a methodology which can be used to translate engineering information, experience, and judgment into a choice of a gamma prior distribution. The proposed methodology assumes that the practicing engineer can provide percentile data relating to either the failure rate or the reliability of the phenomenon being investigated. For example, the methodology will select the gamma prior distribution which conveys an engineer's belief that the failure rate, lambda, simultaneously satisfies the probability statements, P(lambda less than 1.0 x 10 -3 ) = 0.50 and P(lambda less than 1.0 x 10 -5 ) = 0.05. That is, two percentiles provided by an engineer are used to determine a gamma prior model which agrees with the specified percentiles. For those engineers who prefer to specify reliability percentiles rather than the failure-rate percentiles illustrated above, one can use the induced negative-log gamma prior distribution which satisfies the probability statements, P(R(t 0 ) less than 0.99) = 0.50 and P(R(t 0 ) less than 0.99999) = 0.95 for some operating time t 0 . Also, the paper includes graphs for selected percentiles which assist an engineer in applying the methodology

    2011-01-01

    Background Lysozyme c (chicken-type lysozyme) has an important role in host defense, and has been extensively studied as a model in molecular biology, enzymology, protein chemistry, and crystallography. Traditionally, lysozyme c has been considered to be part of a small family that includes genes for two other proteins, lactalbumin, which is found only in mammals, and calcium-binding lysozyme, which is found in only a few species of birds and mammals. More recently, additional testes-expressed members of this family have been identified in human and mouse, suggesting that the mammalian lysozyme gene family is larger than previously known. Results Here we characterize the extent and diversity of the lysozyme gene family in the genomes of phylogenetically diverse mammals, and show that this family contains at least eight different genes that likely duplicated prior to the diversification of extant mammals. These duplicated genes have largely been maintained, both in intron-exon structure and in genomic context, throughout mammalian evolution. Conclusions The mammalian lysozyme gene family is much larger than previously appreciated and consists of at least eight distinct genes scattered around the genome. Since the lysozyme c and lactalbumin proteins have acquired very different functions during evolution, it is likely that many of the other members of the lysozyme-like family will also have diverse and unexpected biological properties.

    Family efficacy, which refers to a family's belief in its ability to produce a desired outcome, has been shown to protect adolescents from risky health behaviors. Few studies have examined family efficacy within diverse populations, however, and understanding of how efficacy is framed and formed within the context of cultural and familial values is limited. This descriptive qualitative study examined sources of family efficacy within ethnically and socioeconomically diverse families, evaluating how such families develop and exercise family efficacy with the intent to protect adolescents from risky health behaviors (i.e., marijuana and alcohol use and early sexual activity). We collected qualitative data via two semi-structured interviews, 4-6 months apart, with 31 adolescents (ages 12-14) and their parent/s, for total of 148 one-on-one interviews. Thematic analysis identified three distinct domains of family efficacy: relational, pragmatic, and value-laden. Prior experiences and cultural background influenced the domain/s utilized by families. Significantly, families that consistently tapped into all three domains were able to effectively manage personal and family difficulties; these families also had family strategies in place to prevent adolescents from risky behaviors. Health professionals could utilize this concept of multidimensional family efficacy to promote health within culturally diverse families. © 2015 Family Process Institute.

    Family presence during resuscitation (FPDR) has advantages for the patients' family member to be present at the bedside. However, FPDR is not regularly practiced by nurses, especially in low to middle income countries. The purpose of this study was to determine Iranian nurses' and family members' attitudes towards FPDR. In a descriptive study, data was collected from the random sample of 178 nurses and 136 family members in four hospitals located in Iran. A 27-item questionnaire was used to collect data on attitudes towards FPDR, and descriptive and correlational analyses were conducted. Of family members, particularly the women, 57.2% (n=78) felt it is their right to experience FPDR and that it has many advantages for the family; including the ability to see that everything was done and worry less. However, 62.5% (n=111) of the nurses disagreed with an adult implementation of FPDR. Nurses perceived FPDR to have many disadvantages. Family members becoming distressed and interfering with the patient which may prolong the resuscitation effort. Nurses with prior education on FPDR were more willing to implement it. FPDR was desired by the majority of family members. To meet their needs, it is important to improve Iranian nurses' views about the advantages of the implementation of FPDR. Education on FPDR is recommended to improve Iranian nurses' views about the advantages of the implementation of FPDR. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Although current irritability and current/prior anxiety have been associated in unipolar depression, these relationships are less well understood in bipolar disorder (BD). We investigated relationships between current irritability and current/prior anxiety as well as other current emotions and BD illness characteristics. Outpatients referred to the Stanford Bipolar Disorders Clinic during 2000-2011 were assessed with the Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation. Prevalence and clinical correlates of current irritability and current/prior anxiety and other illness characteristics were examined. Among 497 BD outpatients (239 Type I, 258 Type II; 58.1% female; mean ± SD age 35.6 ± 13.1 years), 301 (60.6%) had baseline current irritability. Patients with versus without current irritability had significantly higher rates of current anxiety (77.1% versus 42.9%, p anxiety disorder (73.1% versus 52.6%, p anxiety than to current anhedonia, sadness, or euphoria (all p anxiety associations persisted across current predominant mood states. Current irritability was more robustly related to past anxiety than to all other assessed illness characteristics, includingfamily history of mood disorder, history of alcohol/substance use disorder, bipolar subtype, and current syndromal/subsyndromal depression (all p anxiety. Further studies are warranted to assess longitudinal clinical implications of relationships between irritability and anxiety in BD. Copyright © 2016 Elsevier Ltd. All rights reserved.

  7. Penalised Complexity Priors for Stationary Autoregressive Processes

    KAUST Repository

    Sørbye, Sigrunn Holbek

    2017-05-25

    The autoregressive (AR) process of order p(AR(p)) is a central model in time series analysis. A Bayesian approach requires the user to define a prior distribution for the coefficients of the AR(p) model. Although it is easy to write down some prior, it is not at all obvious how to understand and interpret the prior distribution, to ensure that it behaves according to the users\\' prior knowledge. In this article, we approach this problem using the recently developed ideas of penalised complexity (PC) priors. These prior have important properties like robustness and invariance to reparameterisations, as well as a clear interpretation. A PC prior is computed based on specific principles, where model component complexity is penalised in terms of deviation from simple base model formulations. In the AR(1) case, we discuss two natural base model choices, corresponding to either independence in time or no change in time. The latter case is illustrated in a survival model with possible time-dependent frailty. For higher-order processes, we propose a sequential approach, where the base model for AR(p) is the corresponding AR(p-1) model expressed using the partial autocorrelations. The properties of the new prior distribution are compared with the reference prior in a simulation study.

    Our study sought to examine the opioid analgesic (OA) prescribing decisions of emergency department (ED) providers who have themselves used OA therapeutically and those who have not. A second objective was to determine if OA prescribing decisions would differ based on the patient's relationship to the provider. We distributed an electronic survey to a random sample of ED providers at participating centers in a nationwide research consortium. Question topics included provider attitudes about OA prescribing, prior personal therapeutic use of OAs (indications, dosing, and disposal of leftover medication), and hypothetical analgesic-prescribing decisions for their patients, family members, and themselves for different painful conditions. The total survey population was 957 individuals; 515 responded to the survey, a 54% response rate. Prior personal therapeutic OA use was reported in 63% (95% CI = [58-68]). A majority of these providers (82%; 95% CI = [77-87]) took fewer than half the number of pills prescribed. Regarding provider attitudes towards OA prescribing, 66% (95% CI = [61-71]) agreed that OA could lead to addiction even with short-term use. When providers were asked if they would prescribe OA to a patient with 10/10 pain from an ankle sprain, 21% (95% CI = [17-25]) would for an adult patient, 13% (95% CI = [10-16]) would for an adult family member, and 6% (95% CI = [4-8]) indicated they themselves would take an opioid for the same pain. When the scenario involved an ankle fracture, 86% (95% CI = [83-89]) would prescribe OA for an adult patient, 75% (95% CI = [71-79]) for an adult family member, and 52% (95% CI = [47-57]) would themselves take OA. Providers who have personally used OA to treat their pain were found to make similar prescribing decisions compared to those who had not. No consistent differences in prescribing decisions were found between ED providers based on their prior therapeutic use of OA. When making OA prescribing decisions, ED providers

    1990-06-01

    Pregnancy as a transition in family life is perceived as a crisis by many families. Sociodemographic characteristics of families during pregnancy can serve as important sources of information to nurses in drawing out family strengths and providing assistance during this crisis. Family dynamics were measured in 160 women in the third trimester of pregnancy. Half were in their first pregnancy and half were in their second pregnancy. The research question addressed the relationship between family dynamics and several sociodemographic characteristics. Statistically significant relationships were found between the sociodemographic variables of marital and social status, and several dimensions of family dynamics. Families in which couples were married and who enjoyed a higher social status had more positive family dynamics in the dimensions of individuation, stability, flexibility, mutuality and communication. Race, maternal age and parity were not related to level of family dynamics. Strengths in families who have more positive dynamics may be explained by availability of resources, their expertise in using the system, societal approval of marriage and internal family support from the husband. It is essential for nursing care to include systematic family assessment, socialization in effectively using the health care system and individualized family guidance.

  16. Prior CT May Improve Diagnostic Confidence in Myocardial Perfusion Imaging.

    2015-10-01

    Many patients with matching myocardial perfusion imaging defects may have prior CT examinations that include the myocardial region of interest, such as a CT chest or CT abdomen. We correlate these perfusion defects with available prior CT examinations to determine if this will improve diagnostic confidence. Myocardial perfusion scans were reviewed to identify cases with myocardial perfusion defects and prior CT imaging that included the myocardium. The CT was reviewed for evidence of myocardial injury that correlated with the perfusion defect. A retrospective review of 732 myocardial perfusion scans was performed, of which 69 cases with perfusion defects were identified that also had prior CT imaging available for review. Of this subset of patients, 19 patients had findings on the CT scan compatible with ischemia or infarction in the expected region of the perfusion defect, which allowed for a more confident diagnosis. Reviewing a prior CT scan, if available, during the interpretation of a myocardial perfusion scan, can help improve diagnostic confidence in over 25% of cases. This can lead to decreased indeterminate results and can be used to potentially avoid unhelpful further testing.

  17. Pitch perception prior to cortical maturation

    Science.gov (United States)

    Lau, Bonnie K.

    Pitch perception plays an important role in many complex auditory tasks including speech perception, music perception, and sound source segregation. Because of the protracted and extensive development of the human auditory cortex, pitch perception might be expected to mature, at least over the first few months of life. This dissertation investigates complex pitch perception in 3-month-olds, 7-month-olds and adults -- time points when the organization of the auditory pathway is distinctly different. Using an observer-based psychophysical procedure, a series of four studies were conducted to determine whether infants (1) discriminate the pitch of harmonic complex tones, (2) discriminate the pitch of unresolved harmonics, (3) discriminate the pitch of missing fundamental melodies, and (4) have comparable sensitivity to pitch and spectral changes as adult listeners. The stimuli used in these studies were harmonic complex tones, with energy missing at the fundamental frequency. Infants at both three and seven months of age discriminated the pitch of missing fundamental complexes composed of resolved and unresolved harmonics as well as missing fundamental melodies, demonstrating perception of complex pitch by three months of age. More surprisingly, infants in both age groups had lower pitch and spectral discrimination thresholds than adult listeners. Furthermore, no differences in performance on any of the tasks presented were observed between infants at three and seven months of age. These results suggest that subcortical processing is not only sufficient to support pitch perception prior to cortical maturation, but provides adult-like sensitivity to pitch by three months.

    1932-03-01

    Surviving Indian codices and inscriptions, reports written down by the Spanish, and continuity of practice from pre-conquest times are the sources of knowledge about obstetrics in Mexico prior to 1600. Antenatal care included avoidance of exposure to heat, no sleep during the day, and plenty of nourishment, although certain dietary precautions were recommended. Moderate intercourse during the first trimester was permitted but prohibited near the time of parturition. In general, midwives counseled the prospective mother to eat well, to rest physically and mentally, and to engage very moderately in manual labor. Massage was given at regular intervals, and vapor baths were taken. Juices of medicinal plants were administered during labor both to expedite it and to relieve pain. Women assumed a squatting position during labor, which was also assisted by abdominal massage and the manual dilation of the vulva. If parturition was prolonged, pressure was applied by the midwife who used her feet for this purpose. The child was bathed immediately after birth. Lactation was prolonged among the Mexicans.

  19. Prior exposure to interpersonal violence and long-term treatment response for boys with a disruptive behavior disorder.

    Interpersonal violence (IPV) is common in children with a disruptive behavior disorder (DBD) and increases the risk for greater DBD symptom severity, callous-unemotional (CU) traits, and neuroendocrine disruption. Thus, IPV may make it difficult to change symptom trajectories for families receiving DBD interventions given these relationships. The current study examined whether IPV prior to receiving treatment for a DBD predicted trajectories of a variety of associated outcomes, specifically DBD symptoms, CU traits, and cortisol concentrations. Boys with a DBD diagnosis (N = 66; age range = 6-11 years; 54.5% of whom experienced IPV prior to treatment) of either oppositional defiant disorder or conduct disorder participated in a randomized clinical trial and were assessed 3 years following treatment. Multilevel modeling demonstrated that prior IPV predicted smaller rates of change in DBD symptoms, CU traits, and cortisol trajectories, indicating less benefit from intervention. The effect size magnitudes of IPV were large for each outcome (d = 0.88-1.07). These results suggest that IPV is a predictor of the long-term treatment response for boys with a DBD. Including trauma-focused components into existing DBD interventions may be worth testing to improve treatment effectiveness for boys with a prior history of IPV.

    This study examined the role of regular prior technology use in treatment response to an online family problem-solving (OFPS) intervention and an Internet resource intervention (IRI) for pediatric traumatic brain injury (TBI). Participants were 150 individuals in 40 families of children with TBI randomly assigned to OFPS intervention or an IRI. All families received free computers and Internet access to TBI resources. OFPS families received Web-based sessions and therapist-guided synchronous videoconferences focusing on problem solving, communication skills, and behavior management. All participants completed measures of depression, anxiety, and computer usage. OFPS participants rated treatment satisfaction, therapeutic alliance, and Web site and technology comfort. With the OFPS intervention, depression and anxiety improved significantly more among technology using parents (n = 14) than nontechnology users (n = 6). Technology users reported increasing comfort with technology over time, and this change was predictive of depression at followup. Satisfaction and ease-of-use ratings did not differ by technology usage. Lack of regular prior home computer usage and nonadherence were predictive of anxiety at followup. The IRI was not globally effective. However, controlling for prior depression, age, and technology at work, there was a significant effect of technology at home for depression. Families with technology experience at home (n = 11) reported significantly greater improvements in depression than families without prior technology experience at home (n = 8). Although Web-based OFPS was effective in improving caregiver functioning, individuals with limited computer experience may benefit less from an online intervention due to increased nonadherence.

  8. Inference with the Median of a Prior

    Ali Mohammad-Djafari

    2006-06-01

    Full Text Available We consider the problem of inference on one of the two parameters of a probability distribution when we have some prior information on a nuisance parameter. When a prior probability distribution on this nuisance parameter is given, the marginal distribution is the classical tool to account for it. If the prior distribution is not given, but we have partial knowledge such as a fixed number of moments, we can use the maximum entropy principle to assign a prior law and thus go back to the previous case. In this work, we consider the case where we only know the median of the prior and propose a new tool for this case. This new inference tool looks like a marginal distribution. It is obtained by first remarking that the marginal distribution can be considered as the mean value of the original distribution with respect to the prior probability law of the nuisance parameter, and then, by using the median in place of the mean.

  10. Evaluating Prior Learning Assessment Programs: A Suggested Framework

    Directory of Open Access Journals (Sweden)

    Nan L. Travers and Marnie T. Evans

    2011-01-01

    Full Text Available Over the past two decades, American institutions have been expected to include systematic program reviews to meet accrediting standards, either by independent or governmental review agencies. Program evaluation is critical for several reasons: it provides systematic ways to assess what needs improvement or what needs changing and it provides ways to validate practices, whether to internal or external audiences (Mishra, 2007. Most program evaluative models are focused on academic programs, which don’t fit the uniqueness of prior learning assessment programs. This paper proposes an evaluative framework for prior learning assessment programs, which takes into account the type of work within prior learning assessment programs and uses program portfolios, similar to how students are asked to document their work.

    2014-01-01

    Many popular Bayesian nonparametric priors can be characterized in terms of exchangeable species sampling sequences. However, in some applications, exchangeability may not be appropriate. We introduce a novel and probabilistically coherent family of non-exchangeable species sampling sequences characterized by a tractable predictive probability function with weights driven by a sequence of independent Beta random variables. We compare their theoretical clustering properties with those of the Dirichlet Process and the two parameters Poisson-Dirichlet process. The proposed construction provides a complete characterization of the joint process, differently from existing work. We then propose the use of such process as prior distribution in a hierarchical Bayes modeling framework, and we describe a Markov Chain Monte Carlo sampler for posterior inference. We evaluate the performance of the prior and the robustness of the resulting inference in a simulation study, providing a comparison with popular Dirichlet Processes mixtures and Hidden Markov Models. Finally, we develop an application to the detection of chromosomal aberrations in breast cancer by leveraging array CGH data. PMID:25870462

  13. Use of prior odds for missing persons identifications.

    Budowle, Bruce; Ge, Jianye; Chakraborty, Ranajit; Gill-King, Harrell

    2011-06-27

    Identification of missing persons from mass disasters is based on evaluation of a number of variables and observations regarding the combination of features derived from these variables. DNA typing now is playing a more prominent role in the identification of human remains, and particularly so for highly decomposed and fragmented remains. The strength of genetic associations, by either direct or kinship analyses, is often quantified by calculating a likelihood ratio. The likelihood ratio can be multiplied by prior odds based on nongenetic evidence to calculate the posterior odds, that is, by applying Bayes' Theorem, to arrive at a probability of identity. For the identification of human remains, the path creating the set and intersection of variables that contribute to the prior odds needs to be appreciated and well defined. Other than considering the total number of missing persons, the forensic DNA community has been silent on specifying the elements of prior odds computations. The variables include the number of missing individuals, eyewitness accounts, anthropological features, demographics and other identifying characteristics. The assumptions, supporting data and reasoning that are used to establish a prior probability that will be combined with the genetic data need to be considered and justified. Otherwise, data may be unintentionally or intentionally manipulated to achieve a probability of identity that cannot be supported and can thus misrepresent the uncertainty with associations. The forensic DNA community needs to develop guidelines for objectively computing prior odds.

  16. Heuristics as Bayesian inference under extreme priors.

    Science.gov (United States)

    Parpart, Paula; Jones, Matt; Love, Bradley C

    2018-05-01

    Simple heuristics are often regarded as tractable decision strategies because they ignore a great deal of information in the input data. One puzzle is why heuristics can outperform full-information models, such as linear regression, which make full use of the available information. These "less-is-more" effects, in which a relatively simpler model outperforms a more complex model, are prevalent throughout cognitive science, and are frequently argued to demonstrate an inherent advantage of simplifying computation or ignoring information. In contrast, we show at the computational level (where algorithmic restrictions are set aside) that it is never optimal to discard information. Through a formal Bayesian analysis, we prove that popular heuristics, such as tallying and take-the-best, are formally equivalent to Bayesian inference under the limit of infinitely strong priors. Varying the strength of the prior yields a continuum of Bayesian models with the heuristics at one end and ordinary regression at the other. Critically, intermediate models perform better across all our simulations, suggesting that down-weighting information with the appropriate prior is preferable to entirely ignoring it. Rather than because of their simplicity, our analyses suggest heuristics perform well because they implement strong priors that approximate the actual structure of the environment. We end by considering how new heuristics could be derived by infinitely strengthening the priors of other Bayesian models. These formal results have implications for work in psychology, machine learning and economics. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

  17. Dynamic emotion perception and prior expectancy.

    Social interactions require the ability to rapidly perceive emotion from various incoming dynamic, multisensory cues. Prior expectations reduce incoming emotional information and direct attention to cues that are aligned with what is expected. Studies to date have investigated the prior expectancy effect using static emotional images, despite the fact that dynamic stimuli would represent greater ecological validity. The objective of the study was to create a novel functional magnetic resonance imaging (fMRI) paradigm to examine the influence of prior expectations on naturalistic emotion perception. For this purpose, we developed a dynamic emotion perception task, which consisted of audio-visual videos that carry emotional information congruent or incongruent with prior expectations. The results show that emotional congruency was associated with activity in prefrontal regions, amygdala, and putamen, whereas emotional incongruency was associated with activity in temporoparietal junction and mid-cingulate gyrus. Supported by the behavioural results, our findings suggest that prior expectations are reinforced after repeated experience and learning, whereas unexpected emotions may rely on fast change detection processes. The results from the current study are compatible with the notion that the ability to automatically detect unexpected changes in complex dynamic environments allows for adaptive behaviours in potentially advantageous or threatening situations.

  20. Neutrino mass priors for cosmology from random matrices

    Science.gov (United States)

    Long, Andrew J.; Raveri, Marco; Hu, Wayne; Dodelson, Scott

    2018-02-01

    Cosmological measurements of structure are placing increasingly strong constraints on the sum of the neutrino masses, Σ mν, through Bayesian inference. Because these constraints depend on the choice for the prior probability π (Σ mν), we argue that this prior should be motivated by fundamental physical principles rather than the ad hoc choices that are common in the literature. The first step in this direction is to specify the prior directly at the level of the neutrino mass matrix Mν, since this is the parameter appearing in the Lagrangian of the particle physics theory. Thus by specifying a probability distribution over Mν, and by including the known squared mass splittings, we predict a theoretical probability distribution over Σ mν that we interpret as a Bayesian prior probability π (Σ mν). Assuming a basis-invariant probability distribution on Mν, also known as the anarchy hypothesis, we find that π (Σ mν) peaks close to the smallest Σ mν allowed by the measured mass splittings, roughly 0.06 eV (0.1 eV) for normal (inverted) ordering, due to the phenomenon of eigenvalue repulsion in random matrices. We consider three models for neutrino mass generation: Dirac, Majorana, and Majorana via the seesaw mechanism; differences in the predicted priors π (Σ mν) allow for the possibility of having indications about the physical origin of neutrino masses once sufficient experimental sensitivity is achieved. We present fitting functions for π (Σ mν), which provide a simple means for applying these priors to cosmological constraints on the neutrino masses or marginalizing over their impact on other cosmological parameters.

    Provision of contraception is often linked with physical examination, including clinical breast examination (CBE) and pelvic examination. This review was conducted to evaluate the evidence regarding outcomes among women with and without physical examination prior to initiating hormonal contraceptives. The PubMed database was searched from database inception through March 2012 for all peer-reviewed articles in any language concerning CBE and pelvic examination prior to initiating hormonal contraceptives. The quality of each study was assessed using the United States Preventive Services Task Force grading system. The search did not identify any evidence regarding outcomes among women screened versus not screened with CBE prior to initiation of hormonal contraceptives. The search identified two case-control studies of fair quality which compared women who did or did not undergo pelvic examination prior to initiating oral contraceptives (OCs) or depot medroxyprogesterone acetate (DMPA). No differences in risk factors for cervical neoplasia, incidence of sexually transmitted infections, incidence of abnormal Pap smears or incidence of abnormal wet mount findings were observed. Although women with breast cancer should not use hormonal contraceptives, there is little utility in screening prior to initiation, due to the low incidence of breast cancer and uncertain value of CBE among women of reproductive age. Two fair quality studies demonstrated no differences between women who did or did not undergo pelvic examination prior to initiating OCs or DMPA with respect to risk factors or clinical outcomes. In addition, pelvic examination is not likely to detect any conditions for which hormonal contraceptives would be unsafe. Published by Elsevier Inc.

  2. Can natural selection encode Bayesian priors?

    Science.gov (United States)

    Ramírez, Juan Camilo; Marshall, James A R

    2017-08-07

    The evolutionary success of many organisms depends on their ability to make decisions based on estimates of the state of their environment (e.g., predation risk) from uncertain information. These decision problems have optimal solutions and individuals in nature are expected to evolve the behavioural mechanisms to make decisions as if using the optimal solutions. Bayesian inference is the optimal method to produce estimates from uncertain data, thus natural selection is expected to favour individuals with the behavioural mechanisms to make decisions as if they were computing Bayesian estimates in typically-experienced environments, although this does not necessarily imply that favoured decision-makers do perform Bayesian computations exactly. Each individual should evolve to behave as if updating a prior estimate of the unknown environment variable to a posterior estimate as it collects evidence. The prior estimate represents the decision-maker's default belief regarding the environment variable, i.e., the individual's default 'worldview' of the environment. This default belief has been hypothesised to be shaped by natural selection and represent the environment experienced by the individual's ancestors. We present an evolutionary model to explore how accurately Bayesian prior estimates can be encoded genetically and shaped by natural selection when decision-makers learn from uncertain information. The model simulates the evolution of a population of individuals that are required to estimate the probability of an event. Every individual has a prior estimate of this probability and collects noisy cues from the environment in order to update its prior belief to a Bayesian posterior estimate with the evidence gained. The prior is inherited and passed on to offspring. Fitness increases with the accuracy of the posterior estimates produced. Simulations show that prior estimates become accurate over evolutionary time. In addition to these 'Bayesian' individuals, we also

    To report patient/family experiences and outcomes after tracheostomy International survey of patients and families with tracheostomy. Collaboration of the Patient Safety and Quality Improvement Committee of the American Academy of Otolaryngology-Head and Neck Surgery and the Global Tracheostomy Collaborative. A 50-item survey was developed with multistakeholder collaboration. The survey was disseminated via international social networks used by patients with a tracheostomy and their families. Qualitative and quantitative data were analyzed. Of 220 respondents, 90% cared for a pediatric patient with a tracheostomy. Only 48% of respondents felt "very prepared" at time of discharge, and 11% did not receive emergency preparedness training prior to discharge. Home nursing needs were inadequately met in 17% of families, with resulting difficulties shortly after discharge; 14% sought emergent care within 1 week of discharge. Nearly half of respondents indicated a desire to have met with a patient with a tracheostomy prior to surgery but were not offered that opportunity. Fragmented care or limited teamwork was reported by 32% of respondents, whereas tracheotomy care was described as "integrated" or "maximally integrated" for 67%. While many families report satisfaction with tracheostomy care, opportunities remain for improving care. This study highlights the importance of teaching, teamwork, and smoothing transition from the hospital. Potential quality improvement areas include standardizing tracheostomy teaching for routine and emergency needs and optimizing postdischarge support and coordination. Prior to surgery, connecting families to people with a tracheostomy may also be beneficial. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2015.

    In this article, we examine the field of family therapy by drawing a distinction between two forms of practice: Whole Family Therapy (WFT), defined as treating the whole family, and Relational Family Therapy (RFT), defined as working with a subsystem of the family or an individual while retaining a systemic lens. Our thesis is that the practice of WFT has been in decline for some time and steps must be taken to keep it from becoming a defunct practice. We consider the trajectory of WFT and RFT throughout the development of family therapy through reference to the people, the literature, training, and practice patterns associated with family therapy. We remind the reader of the many benefits of WFT and suggest that today WFT is likely to be practiced in conjunction with RFT and individual therapy. Since training of family therapists today is largely located in degree-granting programs, we identify constraints to including WFT in such programs. We conclude by offering suggestions that can enhance a program's ability to train students in WFT. © 2014 FPI, Inc.

    The traditional Bayesian priors for maximum a posteriori (MAP) reconstruction methods usually incorporate local neighborhood interactions that penalize large deviations in parameter estimates for adjacent pixels; therefore, only local pixel differences are utilized. This limits their abilities of penalizing the image roughness. To achieve high-quality PET image reconstruction, this study investigates a MAP reconstruction strategy by incorporating a nonlocal means induced (NLMi) prior (NLMi-MAP) which enables utilizing global similarity information of image. The present NLMi prior approximates the derivative of Gibbs energy function by an NLM filtering process. Specially, the NLMi prior is obtained by subtracting the current image estimation from its NLM filtered version and feeding the residual error back to the reconstruction filter to yield the new image estimation. We tested the present NLMi-MAP method with simulated and real PET datasets. Comparison studies with conventional filtered backprojection (FBP) and a few iterative reconstruction methods clearly demonstrate that the present NLMi-MAP method performs better in lowering noise, preserving image edge and in higher signal to noise ratio (SNR). Extensive experimental results show that the NLMi-MAP method outperforms the existing methods in terms of cross profile, noise reduction, SNR, root mean square error (RMSE) and correlation coefficient (CORR).

    Uganda has one of the highest unmet needs for family planning globally, which is associated with negative health outcomes for women and population-level public health implications. The present cross-sectional study identified factors influencing family planning service uptake and contraceptive use among postpartum women in rural Uganda. Participants were 258 women who attended antenatal care at a rural Ugandan hospital. We used logistic regression models in SPSS to identify determinants of family planning service uptake and contraceptive use postpartum. Statistically significant predictors of uptake of family planning services included: education (AOR = 3.03, 95 % CI 1.57-5.83), prior use of contraceptives (AOR = 7.15, 95 % CI 1.58-32.37), partner communication about contraceptives (AOR = 1.80, 95 % CI 1.36-2.37), and perceived need of contraceptives (AOR = 2.57, 95 % CI 1.09-6.08). Statistically significant predictors of contraceptive use since delivery included: education (AOR = 2.04, 95 % CI 1.05-3.95), prior use of contraceptives (AOR = 10.79, 95 % CI 1.40-83.06), and partner communication about contraceptives (AOR = 1.81, 95 % CI 1.34-2.44). Education, partner communication, and perceived need of family planning are key determinants of postpartum family planning service uptake and contraceptive use, and should be considered in antenatal and postnatal family planning counseling.

    This book presents a systematic and comprehensive treatment of various prior processes that have been developed over the past four decades for dealing with Bayesian approach to solving selected nonparametric inference problems. This revised edition has been substantially expanded to reflect the current interest in this area. After an overview of different prior processes, it examines the now pre-eminent Dirichlet process and its variants including hierarchical processes, then addresses new processes such as dependent Dirichlet, local Dirichlet, time-varying and spatial processes, all of which exploit the countable mixture representation of the Dirichlet process.

    There is a large body of research that shows children from non-intact homes show higher rates of juvenile delinquency than children from intact homes, partially due to weaker parental control and supervision in non-intact homes. What has not been adequately addressed in the research is the influence of changes in family structure among individual adolescents over time on delinquent offending. Using the first and third waves of the National Youth Study, we assess the effect of family structure changes on changes in delinquent offending between waves through the intermediate process of changes in family time and parental attachment. Although prior research has documented adolescents in broken homes are more delinquent than youth in intact homes, the process of family dissolution is not associated with concurrent increases in offending. In contrast, family formation through marriage or cohabitation is associated with simultaneous increases in offending. Changes in family time and parental attachment account for a portion of the family formation effect on delinquency, and prior parental attachment and juvenile offending significantly condition the effect of family formation on offending.

  1. Prior Exposure and Educational Environment towards Entrepreneurial Intention

    Full Text Available This research is based on the responses to a questionnaire applied to 351 students of business management in Chile and Colombia. Through the analysis of structural equations on Ajzen’s model, we found that entrepreneurial education, the University environment, and the prior entrepreneurial exposure are mediated by the factors of the Ajzen`s model to generate entrepreneurial intention in higher education students. The results show that entrepreneurial education strengthens the perceived control of behavior and, with it, albeit in a differentiated way, the entrepreneurial intention of men and women. University environment affects entrepreneurial intention through attitude towards entrepreneurship; and finally, the work experience, used as one of the variables that measure prior entrepreneurial exposure, explains the entrepreneurial intention inversely through the subjective norms. We found that gender has a moderate effect on perceived control of behavior and entrepreneurial education. The scarce studies on the impact of the University environment and the mixed results of the entrepreneurial education and prior entrepreneurial exposure toward entrepreneurial intention show the necessity for further research. A second contribution is the opportunity to present new evidence about the relationship between University environment, entrepreneurial education and prior exposure to developing countries of South America, including the gender effect (moderator for entrepreneurial intention. It is important to note that most of the research in this area applies to developed countries, and some scholars suggest that extrapolating the results is not convenient.

    Cancer is a shared family experience and may provide a "teachable moment" to motivate at-risk family members to adopt cancer prevention and health promotion behaviors. This study explored how a diagnosis of colorectal cancer (CRC) is experienced by family members and may be used to develop a family-based CRC prevention program. Preferences regarding content, timing, and modes of program delivery were examined. Social cognitive theory provided the conceptual framework for the study. This study employed mixed methodology (semi-structured interviews and self-report questionnaires). Participants included 73 adults (21 patients, 52 family members) from 23 families (two patients were deceased prior to being interviewed). Most patients (n = 14; 67 %) were interviewed 1-5 years post-diagnosis. Individual interviews were audio-recorded, transcribed, and content analyzed. For many, a CRC diagnosis was described as a shared family experience. Family members supported each other's efforts to prevent CRC through screening, exercising, and maintaining a healthy diet. Teachable moments for introducing a family-based program included the time of the patient's initial cancer surgery and post-chemotherapy. Reported willingness to participate in a family-based program was associated with risk perception, self-efficacy, outcome expectancies, and the social/community context in which the program would be embedded. Program preferences included cancer screening, diet/nutrition, weight management, stress reduction, and exercise. Challenges included geographic dispersion, variation in education levels, generational differences, and scheduling. CRC patients and family members are receptive to family-based programs. Feasibility concerns, which may be mitigated but not eliminated with technological advances, must be addressed for successful family-based programs.

  6. PIRPLE: a penalized-likelihood framework for incorporation of prior images in CT reconstruction

    Stayman, J Webster; Dang, Hao; Ding, Yifu; Siewerdsen, Jeffrey H

    2013-01-01

    Over the course of diagnosis and treatment, it is common for a number of imaging studies to be acquired. Such imaging sequences can provide substantial patient-specific prior knowledge about the anatomy that can be incorporated into a prior-image-based tomographic reconstruction for improved image quality and better dose utilization. We present a general methodology using a model-based reconstruction approach including formulations of the measurement noise that also integrates prior images. This penalized-likelihood technique adopts a sparsity enforcing penalty that incorporates prior information yet allows for change between the current reconstruction and the prior image. Moreover, since prior images are generally not registered with the current image volume, we present a modified model-based approach that seeks a joint registration of the prior image in addition to the reconstruction of projection data. We demonstrate that the combined prior-image- and model-based technique outperforms methods that ignore the prior data or lack a noise model. Moreover, we demonstrate the importance of registration for prior-image-based reconstruction methods and show that the prior-image-registered penalized-likelihood estimation (PIRPLE) approach can maintain a high level of image quality in the presence of noisy and undersampled projection data.

    Full Text Available Current paper describes the application of an innovative strategy to teach family, within a hospital context, by sensitizing nurses on the family subject through the use of a game. Given the hospitalization of a relative, the family faces changes in its dynamics caused by the crisis it is exposed to. It is the relevance for including the family within the care process. Since nurses are expected to assume a key role for which they need specific competence to intervene in families when experiencing an eventual crisis. The in-service education becomes a strategy of generating new skills and enhances human capital to improve the quality of nursing care. Considering the importance of including family in the care context, a playful tool called Family Nursing Game has been invented for teaching the family, especially by passing a model of family intervention. The strategy is based on the belief of the existence of relationship between game and learning.

    We studied the characteristics of family functioning in bipolar children and healthy comparison children. We hypothesized that the family environment of bipolar children would show greater levels of dysfunction as measured by the Family Environment Scale (FES). We compared the family functioning of 36 families that included a child with DSM-IV bipolar disorder versus 29 comparison families that included only healthy children. All subjects and their parents were assessed with the K-SADS-PL interview. The parents completed the FES to assess their current family functioning. Multivariate analysis of variance was used to compare the family environment of families with and without offspring with bipolar disorder. Parents of bipolar children reported lower levels of family cohesion (pconflict (pfamilies where a parent had a history of mood disorders compared to families where parents had no history of mood disorders. Length of illness in the affected child was inversely associated with family cohesion (r=-0.47, p=0.004). Due to the case-control design of the study, we cannot comment on the development of these family problems or attribute their cause specifically to child bipolar disorder. Families with bipolar children show dysfunctional patterns related to interpersonal interactions and personal growth. A distressed family environment should be addressed when treating children with bipolar disorder.

    2017-11-01

    All family medicine programs are required to provide specialty-specific didactic conferences for residents. Since a baseline study of family medicine didactic formats was published in 2000, training requirements have changed, core content has evolved, and new teaching strategies have been recommended. The present study examines the characteristics of current family medicine didactics, compares current and past conference format data, and identifies factors affecting content selection. The survey used in the prior conference formats study was distributed to all US family medicine programs. All questions from the original survey were repeated, and items regarding factors affecting conference content and threats to conferences were added. The survey response rate was 66%. The majority of family medicine programs endorse block formats for structuring conferences. Compared to the original study, programs are devoting significantly more hours to didactics on fewer days. Family medicine faculty and residents are responsible for 70% of didactic offerings (also a significant shift), and 87% of programs use a core curriculum. In over 70% of programs, some residents are unavailable for conferences due to work restrictions or service demands. The Accreditation Council for Graduate Medical Education subcompetencies and Milestones have only a moderate impact on topic selection. Family medicine didactics have evolved in the past 15 years with a notable increase in reliance upon core faculty and residents to lead conferences. Reduced availability of residents prevents all residents from having full exposure to the didactic curriculum. Family medicine faculty who are taking greater responsibility for didactics are also faced with increased clinical and administrative duties.

    Experts recommend that clinicians assess motivational factors before initiating care for pediatric obesity. Currently, there are no well-established clinical tools available for assessing motivation in youth with obesity or their families. This represents an important gap in knowledge since motivation-related information may shed light on which patients might fail to complete treatment programs. Our study was designed to evaluate the measurement properties and utility of the Readiness and Motivational Interview for Families (RMI-Family), a structured interview that utilizes a motivational interviewing approach to (i) assess motivational factors in youth and their parents, and (ii) examine the degree to which motivation and motivation-related concordance between youth and parents are related to making changes to lifestyle habits for managing obesity in youth. From 2016 to 2020, this prospective study will include youth with obesity (body mass index [BMI] ≥97th percentile; 13-17 years old; n = 250) and their parents (n = 250). The study will be conducted at two primary-level, multidisciplinary obesity management clinics based at children's hospitals in Alberta, Canada. Participants will be recruited and enrolled after referral to these clinics, but prior to initiating clinical care. Each youth and their parent will complete the RMI-Family (~1.5 h) at baseline, and 6- and 12-months post-baseline. Individual (i.e., youth or parent) and family-level (i.e., across youth and parent) responses to interview questions will be scored, as will aspects of interview administration (e.g., fidelity to motivational interviewing tenets). The RMI-Family will also be examined for test-retest reliability. Youth data collected at each time point will include demography, anthropometry, lifestyle habits, psychosocial functioning, and health services utilization.

    In this study, we investigate the application of multi-parametric anato-functional (MR-PET) priors for the maximum a posteriori (MAP) reconstruction of brain PET data in order to address the limitations of the conventional anatomical priors in the presence of PET-MR mismatches. In addition to partial volume correction benefits, the suitability of these priors for reconstruction of low-count PET data is also introduced and demonstrated, comparing to standard maximum-likelihood (ML) reconstruction of high-count data. The conventional local Tikhonov and total variation (TV) priors and current state-of-the-art anatomical priors including the Kaipio, non-local Tikhonov prior with Bowsher and Gaussian similarity kernels are investigated and presented in a unified framework. The Gaussian kernels are calculated using both voxel- and patch-based feature vectors. To cope with PET and MR mismatches, the Bowsher and Gaussian priors are extended to multi-parametric priors. In addition, we propose a modified joint Burg entropy prior that by definition exploits all parametric information in the MAP reconstruction of PET data. The performance of the priors was extensively evaluated using 3D simulations and two clinical brain datasets of [ 18 F]florbetaben and [ 18 F]FDG radiotracers. For simulations, several anato-functional mismatches were intentionally introduced between the PET and MR images, and furthermore, for the FDG clinical dataset, two PET-unique active tumours were embedded in the PET data. Our simulation results showed that the joint Burg entropy prior far outperformed the conventional anatomical priors in terms of preserving PET unique lesions, while still reconstructing functional boundaries with corresponding MR boundaries. In addition, the multi-parametric extension of the Gaussian and Bowsher priors led to enhanced preservation of edge and PET unique features and also an improved bias-variance performance.

  15. Random template placement and prior information

    Roever, Christian

    2010-01-01

    In signal detection problems, one is usually faced with the task of searching a parameter space for peaks in the likelihood function which indicate the presence of a signal. Random searches have proven to be very efficient as well as easy to implement, compared e.g. to searches along regular grids in parameter space. Knowledge of the parameterised shape of the signal searched for adds structure to the parameter space, i.e., there are usually regions requiring to be densely searched while in other regions a coarser search is sufficient. On the other hand, prior information identifies the regions in which a search will actually be promising or may likely be in vain. Defining specific figures of merit allows one to combine both template metric and prior distribution and devise optimal sampling schemes over the parameter space. We show an example related to the gravitational wave signal from a binary inspiral event. Here the template metric and prior information are particularly contradictory, since signals from low-mass systems tolerate the least mismatch in parameter space while high-mass systems are far more likely, as they imply a greater signal-to-noise ratio (SNR) and hence are detectable to greater distances. The derived sampling strategy is implemented in a Markov chain Monte Carlo (MCMC) algorithm where it improves convergence.

    Abstract Military life presents a variety of challenges to military families, including frequent separations and relocations as well as the risks that service members face during deployment; however, many families successfully navigate these challenges. Despite a recent emphasis on family resilience, the U.S. Department of Defense (DoD) does not have a standard and universally accepted definition of family resilience. A standard definition is a necessary for DoD to more effectively assess its efforts to sustain and improve family resilience. RAND authors reviewed the literature on family resilience and, in this study, recommend a definition that could be used DoD-wide. The authors also reviewed DoD policies related to family resilience, reviewed models that describe family resilience and identified key family resilience factors, and developed several recommendations for how family-resilience programs and policies could be managed across DoD.

    Previous studies on family meals and disordered eating have mainly drawn their samples from the general population. The goal of the current study is to determine family meal frequency among children and adolescents with anorexia nervosa (AN), bulimia nervosa (BN), and feeding or eating disorder not elsewhere classified (FED-NEC) and to examine whether family meal frequency is associated with eating disorder psychopathology. Participants included 154 children and adolescents (M = 14.92 ± 2.62), who met criteria for AN (n = 60), BN (n = 32), or FED-NEC (n = 62). All participants completed the Eating Disorder Examination and the Family Meal Questionnaire prior to treatment at the University of Chicago Eating Disorders Program. AN and BN participants significantly differed in terms of family meal frequency. A majority of participants with AN (71.7%), compared with less than half (43.7%) of participants with BN, reported eating dinner with their family frequently (five or more times per week). Family meal frequency during dinner was significantly and negatively correlated with dietary restraints and eating concerns among participants with BN (r = -.381, r = -.366, p meal frequency may be explained by their parents' relatively greater vigilance over eating, whereas families of BN patients may be less aware of eating disorder behaviors and hence less insistent upon family meals. Additionally, children and adolescents with AN may be more inhibited and withdrawn and therefore are perhaps more likely to stay at home and eat together with their families.

    Minimizing collective radiation exposure and producing free-release material are two of the highest priorities in the decommissioning of a Nuclear Power Plant (NPP). Full System Decontamination (FSD) is the most effective measure to reduce source term and remove oxide layer contamination within the plant systems. FSD is typically a decontamination of the primary coolant circuit and the auxiliary systems. In recent years AREVA NP has performed several FSDs in PWRs and BWRs prior to decommissioning by applying the proprietary CORD copyright family and AMDA copyright technology. Chemical Oxidation Reduction Decontamination or CORD represents the chemical decontamination process while AMDA stands for Automated Mobile Decontamination Appliance, AREVA NPs decontamination equipment. Described herein are the excellent results achieved for the FSDs applied at the German PWRs Stade in 2004 and Obrigheim in 2007 and for the FSDs performed at the Swedish BWRs, Barsebaeck Unit 1 in 2007 and Barsebaeck Unit 2 in 2008. All four FSDs were performed using the AREVA NP CORD family decontamination technology in combination with the AREVA NP decontamination equipment, AMDA. (orig.)

    Facilitated family presence at resuscitation is endorsed by multiple nursing and specialty practice organizations. Implementation of this practice is not universal so there is a need to increase familiarity and competence with facilitated family presence at resuscitation during this significant life event. One strategy to promote this practice is to use a nursing student toolkit for pre-licensure and graduate nursing students. The toolkit includes short video simulations of facilitated family presence at resuscitation, a PowerPoint presentation of evidence-based practice, and questions to facilitate guided discussion. This study tested the effectiveness of this toolkit in increasing nursing students' knowledge, perceptions, and confidence in facilitated family presence at resuscitation. Nursing students from five universities in the United States completed the Family Presence Risk-Benefit Scale, Family Presence Self-Confidence Scale, and a knowledge test before and after the intervention. Implementing the facilitated family presence at resuscitation toolkit significantly increased nursing students' knowledge, perceptions, and confidence related to facilitated family presence at resuscitation (pfamily presence at resuscitation toolkit used in this study had a positive impact on students' knowledge, perception of benefits and risks, and self-confidence in facilitated family presence at resuscitation. The toolkit provides students a structured opportunity to consider the presence of family members at resuscitation prior to encountering this situation in clinical practice.

    Prior research has established that adolescents' perceptions of family belonging are associated with a range of well-being indicators and that adolescents in stepfamilies report lower levels of family belonging than adolescents in two-biological-parent families. Yet, we know little regarding what factors are associated with adolescents' perceptions of family belonging in stepfamilies. Guided by family systems theory, the authors addressed this issue by using nationally representative data (Add Health) to examine the associations between family characteristics and adolescents' perceptions of family belonging in stepfather families ( N = 2,085). Results from structural equation models revealed that both the perceived quality of the stepfather-adolescent relationship, and in particular the perceived quality of the mother-adolescent relationship, were the factors most strongly associated with feelings of family belonging.

    Disability is part of life for most contemporary families, but to date the literature on disability in families is fragmented and narrow. This editorial commentary introduces the content and findings of peer-reviewed articles appearing in a special issue of Family Relations. The editors outline unanswered but core research questions and preview the themes present in the issue: families with disabilities are diverse; economic hardship disproportionately characterizes their lives; family life with disabilities is a journey that includes stress and resilience, with support contributing significantly to the latter; and that work benefits and taxes family life. Articles extrapolate beyond findings to explore implications for family policy and practice. The editors assert that developing understanding of how disability influences families requires a more diverse and rigorous research portfolio. They further cite the need to embed disability as a variable in a range of family studies and advocate more outlets for publication.

    The national policies for the education/training of adults are in the 21st century highly influenced by proposals which are formulated and promoted by The European Union (EU) as well as other transnational players and this shift in policy making has consequences. One is that ideas which in the past...... would have been categorized as utopian can become realpolitik. Validation of Prior Learning (VPL) was in Europe mainly regarded as utopian while universities in the United States of America (USA) were developing ways to obtain credits to those students which was coming with experiences from working life....

    Despite genetic advances in the study of Lynch syndrome (LS), difficulties remain in the diagnosis of the syndrome. The aim of this study was to assess the usefulness of a detailed genealogical tree as a screening method to identify Tenerife island families with a high probability of LS. We elaborated complete genealogical trees of the families. According to the degree of fulfillment of the Amsterdam Criteria II, the genealogical trees were classified as high or low probability of LS. Additionally, we analyzed the level of tumor microsatellite instability (MSI+) and identified a mutation in exon 13 of the MSH2 gene by single-strand conformation polymorphism, sequencing, and PCR-RFLP. According the genealogical trees, we found 10 families with high probability of LS and 30 families with low probability of LS. The families with high probability of LS showed high MSI+ in all cases. Conversely, families with low probability were MSS (microsatellite stable). In 5 of the 10 families with high probability, we discovered a T-->G mutation in position 688 of exon 13 of MSH2, which appeared in all the family members with the tumor, except 1 patient with a retinoblastoma. Our results indicate that genealogical tree is a highly effective tool for classifying families with a high probability of Lynch Syndrome prior to genetic test.

    To report a concept analysis of family homeostasis. As family members are a majority of informal caregivers, negative consequences from caregiving duty create a vicious cycle in the family unit resulting in ongoing health crises and care challenges. Concept analysis. Forty empirical studies published from 1956-2012 were selected by searching five electronic bibliographical databases and by a manual search conducted from 2012-2013. Search terms included 'family homeostasis', 'homeostasis in family', 'homeostatic care' and 'family equilibrium'. Clinical experiences in nursing practice were used for constructing cases and clinical implications. Walker and Avant's method guided this analysis. Family homeostasis is defined as the capacity and mechanisms by which equilibrium is re-established in the family after a change occurs. Five critical attributes are identified: (1) predetermined setpoint; (2) self-appraised antecedents; (3) interdependence; (4) tendency to stability; and (5) feedback mechanisms. Antecedents include any type of causative change beyond the tolerable limit, while consequences encompass intermediate and long-term outcomes as well as equilibrium itself. Family homeostasis provides a conceptual rationale of family caregiving. While care recipients remain the primary beneficiaries of healthcare provision, homeostatic mechanisms are required to support the family caregiver's valuable contribution in the caring process to enhance family well-being. Further study should expand the definition and settings of family to reflect healthcare needs of diverse types of families and from the perspectives of different healthcare providers. © 2014 John Wiley & Sons Ltd.

    The aim of this study is to use data from a non-interventional study of adalimumab in patients with rheumatoid arthritis (RA) during routine clinical practice to evaluate the impact of prior treatment with biologics on the effectiveness of current therapy. Efficacy parameters were evaluated for all patients with values at baseline and month 12. Subgroup analyses were performed on patients with 0, 1, or ≥2 prior biologic agents. Key outcome measures included Disease Activity Score- 28 joints (DAS28) and Funktionsfragebogen Hannover (FFbH) functional ability score. A total of 4700 RA adalimumab-treated patients were included in this analysis. Baseline disease activity increased with an increasing number of prior biologic agents and therapeutic response diminished. After 12 months of adalimumab therapy, DAS28 and FFbH scores showed improvements in all groups, but the group with 0 prior biologic agents had the best outcomes, while the group with ≥2 prior biologic agents had the worst. Clinical response (EULAR and DAS28-dcrit) and remission rates showed a similar pattern. Nevertheless, 44% to 67% of patients treated with ≥2 prior biologic agents achieved a clinical response. Multiple regression analyses identified prior biologic therapy as a significant negative predictor for response to therapy. Treatment with adalimumab leads to decreases in disease activity and improvements in function. Improvements are most pronounced in patients with 0 or 1 prior biologic agent, but a substantial proportion of patients treated with ≥2 prior biologic agents experience significant benefit from adalimumab therapy.

  11. Prior Pronunciation Knowledge Bootstraps Word Learning

    Full Text Available Learners often struggle with L2 sounds, yet little is known about the role of prior pronunciation knowledge and explicit articulatory training in language acquisition. This study asks if existing pronunciation knowledge can bootstrap word learning, and whether short-term audiovisual articulatory training for tongue position with and without a production component has an effect on lexical retention. Participants were trained and tested on stimuli with perceptually salient segments that are challenging to produce. Results indicate that pronunciation knowledge plays an important role in word learning. While much about the extent and shape of this role remains unclear, this study sheds light in three main areas. First, prior pronunciation knowledge leads to increased accuracy in word learning, as all groups trended toward lower accuracy on pseudowords with two novel segments, when compared with those with one or none. Second, all training and control conditions followed similar patterns, with training neither aiding nor inhibiting retention; this is a noteworthy result as previous work has found that the inclusion of production in training leads to decreased performance when testing for retention. Finally, higher production accuracy during practice led to higher retention after the word-learning task, indicating that individual differences and successful training are potentially important indicators of retention. This study provides support for the claim that pronunciation matters in L2 word learning.

  12. Prior knowledge-based approach for associating ...

    Science.gov (United States)

    Evaluating the potential human health and/or ecological risks associated with exposures to complex chemical mixtures in the ambient environment is one of the central challenges of chemical safety assessment and environmental protection. There is a need for approaches that can help to integrate chemical monitoring and bio-effects data to evaluate risks associated with chemicals present in the environment. We used prior knowledge about chemical-gene interactions to develop a knowledge assembly model for detected chemicals at five locations near two wastewater treatment plants. The assembly model was used to generate hypotheses about the biological impacts of the chemicals at each location. The hypotheses were tested using empirical hepatic gene expression data from fathead minnows exposed for 12 d at each location. Empirical gene expression data was also mapped to the assembly models to statistically evaluate the likelihood of a chemical contributing to the observed biological responses. The prior knowledge approach was able reasonably hypothesize the biological impacts at one site but not the other. Chemicals most likely contributing to the observed biological responses were identified at each location. Despite limitations to the approach, knowledge assembly models have strong potential for associating chemical occurrence with potential biological effects and providing a foundation for hypothesis generation to guide research and/or monitoring efforts relat

    For children with chronic conditions, well-being is closely related to how well their families function. Most prior research syntheses on family functioning and child well-being have focused on children with a single condition, thereby limiting the potential to aggregate and build on what is known across conditions. To address this challenge, research reports were reviewed and meta-analyses conducted of findings on the relationship between family functioning and child well-being across a range of chronic physical conditions. The sample was derived from a larger systematic review study that included 1,028 reports published between January 1, 2000 and March 31, 2014. The current review includes 53 studies in which a relationship between family functioning and child well-being was analyzed using one of four family measures: Family Adaptability and Cohesion Evaluation Scales, Family Environment Scale, Family Relationship Index, or Family Assessment Device. Most studies were cross-sectional and observational (n = 43, 81%). The most frequently studied conditions were diabetes, cancer, sickle cell disease, and asthma. In 37 studies, findings were sufficiently comparable to conduct meta-analyses. Significant correlations were identified between children's psychological health and seven of nine dimensions of family functioning. Significant correlations also were found between dimensions of family functioning and children's problem behaviors, social competence, quality of life, and, to a lesser extent, adherence and physical health. Of the family dimensions, cohesion and conflict were associated most strongly with child outcomes. Understanding the specific family variables, such as conflict, linked to varied child outcomes is key for intervention development. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

    More than 100 delegates from many African countries attended a seminar on the role of family planning in African development, which was held at the University College in Nairobi, Kenya from December 12-16, 1967. This article outlines some courses of action suggested at the session dealing with the training of family planning personnel. Medical schools should ideally include family planning in their curricula and should be encouraged to set up family planning clinics as part of the teaching facilities. African students studying overseas should adapt their learning to their own countries. General practitioners need at least a 3-day intensive course in family planning. The training of paramedical personnel is also discussed.

    Infants with minor abusive injuries are at risk for more serious abusive injury, including abusive head trauma (AHT). Our study objective was to determine if children with AHT had prior opportunities to detect abuse and to describe the opportunities. All AHT cases from 7/1/2009 to 12/31/2011 at four tertiary care children's hospitals were included. A prior opportunity was defined as prior evaluation by either a medical or child protective services (CPS) professional when the symptoms and/or referral could be consistent with abuse but the diagnosis was not made and/or an alternate explanation was given and accepted. Two-hundred-thirty-two children with AHT were identified; median age (IQR) was 5.40 (3.30, 14.60) months. Ten percent (22/232) died. Of the 232 patients diagnosed with AHT, 31% (n=73) had a total of 120 prior opportunities. Fifty-nine children (25%) had at least one prior opportunity to identify abuse in a medical setting, representing 98 prior opportunities. An additional 14 (6%) children had 22 prior opportunities through previous CPS involvement. There were no differences between those with and without a prior opportunity based on age, gender, race, insurance, mortality, or institution. Children with prior opportunities in a medical setting were more likely to have chronic subdural hemorrhage (48 vs. 17%, p<0.01) and healing fractures (31 vs. 19%, p=0.05). The most common prior opportunities included vomiting 31.6% (38/120), prior CPS contact 20% (24/120), and bruising 11.7% (14/120). Improvements in earlier recognition of AHT and subsequent intervention might prevent additional injuries and reduce mortality. Copyright © 2016 Elsevier Ltd. All rights reserved.

    X-ray computed tomography (CT) has been widely used to provide patient-specific anatomical information in the forms of tissue attenuation. However, the cumulative radiation induced in CT scan has raised extensive concerns in recently years. How to maintain reconstruction image quality is a major challenge for low-dose CT (LDCT) imaging. Generally, LDCT imaging can be greatly improved by incorporating prior knowledge in some specific forms. A joint estimation framework termed discriminative prior-prior image constrained compressed sensing (DP-PICCS) reconstruction is proposed in this paper. This DP-PICCS algorithm utilizes discriminative prior knowledge via two feature dictionary constraints which built on atoms from the samples of tissue attenuation feature patches and noise-artifacts residual feature patches, respectively. Also, the prior image construction relies on a discriminative feature representation (DFR) processing by two feature dictionary. Its comparison to other competing methods through experiments on low-dose projections acquired from torso phantom simulation study and clinical abdomen study demonstrated that the DP-PICCS method achieved promising improvement in terms of the effectively-suppressed noise and the well-retained structures.

  20. Variable Selection with Prior Information for Generalized Linear Models via the Prior LASSO Method

    Jiang, Yuan; He, Yunxiao

    2015-01-01

    LASSO is a popular statistical tool often used in conjunction with generalized linear models that can simultaneously select variables and estimate parameters. When there are many variables of interest, as in current biological and biomedical studies, the power of LASSO can be limited. Fortunately, so much biological and biomedical data have been collected and they may contain useful information about the importance of certain variables. This paper proposes an extension of LASSO, namely, prior LASSO (pLASSO), to incorporate that prior information into penalized generalized linear models. The goal is achieved by adding in the LASSO criterion function an additional measure of the discrepancy between the prior information and the model. For linear regression, the whole solution path of the pLASSO estimator can be found with a procedure similar to the Least Angle Regression (LARS). Asymptotic theories and simulation results show that pLASSO provides significant improvement over LASSO when the prior information is relatively accurate. When the prior information is less reliable, pLASSO shows great robustness to the misspecification. We illustrate the application of pLASSO using a real data set from a genome-wide association study.

    Full Text Available Background: Adolescents in India choose career in medicine under the influence and pressure from parents, family members, peers and external sources. There are no measures taken to study whether these medical students understand the demands and priorities of a career in medicine once they decide to choose it. Hence the study was undertaken at PIMS-DU with Ist year MBBS students as participants. Aims: 1 Assess the factors influencing the choice of MBBS. 2 Analyze the prior knowledge and awareness of medical students regarding the course. 3 Their career trend in future. Material and Methods: All newly admitted students present at the orientation programme in September 2014 at PIMS –DU were included as participants. Their written responses to a 14 point questionnaire were entered into a Microsoft Excel Spreadsheet and descriptive analysis was done. Results: A majority of students had their parents and family members in medical profession indicating prior idea amongst the students regarding the course, even when the choice was made at an early stage of academics or without appearing for aptitude tests due to unawareness. Appearance for entrance exams to kept their options wide open but caused unnecessary stress, anxiety and economic burden to parents. However, these participants had limited knowledge about medical curriculum but had decisive ideas regarding future trend in career. Conclusions: Family being strong motivator for career choice for medical students; should encourage students to undertake aptitude tests, career guidance courses and investigate about future prospects to create a strong foundation as MBBS students.

    In extended linear models the input space is projected onto a feature space by means of an arbitrary non-linear transformation. A linear model is then applied to the feature space to construct the model output. The dimension of the feature space can be very large, or even infinite, giving the model...... a very big flexibility. Support Vector Machines (SVM's) and Gaussian processes are two examples of such models. In this technical report I present a model in which the dimension of the feature space remains finite, and where a Bayesian approach is used to train the model with Gaussian priors...... on the parameters. The Relevance Vector Machine, introduced by Tipping, is a particular case of such a model. I give the detailed derivations of the expectation-maximisation (EM) algorithm used in the training. These derivations are not found in the literature, and might be helpful for newcomers....

    The issue of parental involvement in an adolescent's decision to abort a pregnancy is complex and controversial. Consequently, the impact of legislation to mandate parental involvement is reviewed. Although the costs of such legislation are high, there are at least three important clinical benefits. First, a legal mandate will require many adolescents who would not otherwise involve their parents in this decision process to seek their counsel and emotional support. Second, parent's responsibility for the actions of their adolescent children is acknowledged within the legal system. Third, family unity may be promoted by allowing parents and adolescents an opportunity to deal more openly with the causes and implications of the pregnancy.

  5. Savings for visuomotor adaptation require prior history of error, not prior repetition of successful actions.

    When we move, perturbations to our body or the environment can elicit discrepancies between predicted and actual outcomes. We readily adapt movements to compensate for such discrepancies, and the retention of this learning is evident as savings, or faster readaptation to a previously encountered perturbation. The mechanistic processes contributing to savings, or even the necessary conditions for savings, are not fully understood. One theory suggests that savings requires increased sensitivity to previously experienced errors: when perturbations evoke a sequence of correlated errors, we increase our sensitivity to the errors experienced, which subsequently improves error correction (Herzfeld et al. 2014). An alternative theory suggests that a memory of actions is necessary for savings: when an action becomes associated with successful target acquisition through repetition, that action is more rapidly retrieved at subsequent learning (Huang et al. 2011). In the present study, to better understand the necessary conditions for savings, we tested how savings is affected by prior experience of similar errors and prior repetition of the action required to eliminate errors using a factorial design. Prior experience of errors induced by a visuomotor rotation in the savings block was either prevented at initial learning by gradually removing an oppositely signed perturbation or enforced by abruptly removing the perturbation. Prior repetition of the action required to eliminate errors in the savings block was either deprived or enforced by manipulating target location in preceding trials. The data suggest that prior experience of errors is both necessary and sufficient for savings, whereas prior repetition of a successful action is neither necessary nor sufficient for savings.

    To investigate structural brain connectome alterations in cirrhotic patients with prior overt hepatic encephalopathy (OHE). Seventeen cirrhotic patients with prior OHE (prior-OHE), 18 cirrhotic patients without prior OHE (non-prior-OHE) and 18 healthy controls (HC) underwent diffusion tensor imaging. Neurocognitive functioning was assessed with Psychometric Hepatic Encephalopathy Score (PHES). Using a probabilistic fibre tracking approach, we depicted the whole-brain structural network as a connectivity matrix of 90 regions (derived from the Automated Anatomic Labeling atlas). Graph theory-based analyses were performed to analyse topological properties of the brain network. The analysis of variance showed significant group effects on several topological properties, including network strength, global efficiency and local efficiency. A progressive decrease trend for these metrics was found from non-prior-OHE to prior-OHE, compared with HC. Among the three groups, the regions with altered nodal efficiency were mainly distributed in the frontal and occipital cortices, paralimbic system and subcortical regions. The topological metrics, such as network strength and global efficiency, were correlated with PHES among cirrhotic patients. The cirrhotic patients developed structural brain connectome alterations; this is aggravated by prior OHE episode. Disrupted topological organization of the brain structural network may account for cognitive impairments related to prior OHE. (orig.)

    The aim of modern obstetrics is to bring a healthy child to a healthy mother. Preconception counseling is a form of preventive medicine that consists of three main components: risk assessment, health promotion and intervention, in order to improve pregnancy outcome. A large proportion of women, who need assisted reproductive technologies (ART) due to infertility, are older than the average pregnant women. The risk for chronic maternal disease such as obesity, diabetes mellitus, chronic hypertension, cardiovascular diseases and malignant disease greatly increases with maternal age. Chronic maternal illness might increase the risk of in vitro fertilization procedure and is also associated with increased obstetrics risk and even death. A previous study has shown that most maternal deaths in the USA, due to chronic maternal disease, are potentially preventable through better medical care from preconception, yet most studies that deal with preconception care in infertility patients only address the problems of infertility. Therefore, similar to the recommendations of the American Heart Association before non-competitive physical activity, and the American Society of Anesthesiologists before an elective surgery, we suggest a pre-ART medical assessment. Our objective is to outline the potential risks for older women who undergo ART procedure and potentially, pregnancy, and to characterize guidelines for evaluation prior to enrolling them in ART programs. Pre-ART assessment should include a thorough medical questionnaire and medical examination. Appropriate treatment for women with medical conditions prior to ART procedure and optimizing disease control in preparation for pregnancy including changing a potentially teratogenic treatment, can improve women's health status prior to pregnancy and reduce pregnancy related complications. At the end of the evaluation, and before ART treatment, the women should be consulted, based on the results of tests, on the possible risks

    To determine how different types of prior knowledge (declarative and procedural) impact student achievement and how prior-knowledge assessment can be used as an instructional design tool. A questionnaire was developed based on the prior-knowledge model, which distinguishes between declarative and procedural knowledge. One hundred fifteen pharmacy students were tested prior to beginning 4 successive basic science courses and then prior to beginning a pharmaceutical chemistry course. Regression analysis was used to determine which type of knowledge was the best predictor of student achievement. The 4 course instructors were interviewed and their comments analyzed. Prior knowledge from previous courses significantly influenced student achievement. Procedural knowledge was especially related to student achievement. Instructors and students had mainly positive reactions towards the prior-knowledge tests. Students' prior knowledge should be taken into consideration in instructional design and curriculum planning. Furthermore, the results of prior-knowledge assessments may be used as a tool for student support in addressing areas of deficiency.

Very little is known about the backgrounds and prior knowledge of these students. In this talk we present the results of a survey of our Astronomy MOOC students. We also compare these results to our previous work on undergraduate students in introductory astronomy courses. Survey questions examined student demographics and motivations as well as their science and information literacy (including basic science knowledge, interest, attitudes and beliefs, and where they get their information about science). We found that our MOOC students are different than the undergraduate students in more ways than demographics. Many MOOC students demonstrated high levels of science and information literacy. With a more comprehensive understanding of our students’ motivations and prior knowledge about science and how they get their information about science, we will be able to develop more tailored learning experiences for these lifelong learners.

    Recent studies have suggested that the onset of sleepwalking episodes may be preceded by fluctuations in slow-wave sleep electroencephalographic characteristics. However, whether or not such fluctuations are specific to sleepwalking episodes or generalized to all sleep-wake transitions in sleepwalkers remains unknown. The goal of this study was to compare spectral power for delta (1-4 Hz) and slow delta (0.5-1 Hz) as well as slow oscillation density before the onset of somnambulistic episodes versus non-behavioral awakenings recorded from the same group of sleepwalkers. A secondary aim was to describe the time course of observed changes in slow-wave activity and slow oscillations during the 3 min immediately preceding the occurrence of somnambulistic episodes. Twelve adult sleepwalkers were investigated polysomnographically during the course of one night. Slow-wave activity and slow oscillation density were significantly greater prior to patients' somnambulistic episodes as compared with non-behavioral awakenings. However, there was no evidence for a gradual increase over the 3 min preceding the episodes. Increased slow-wave activity and slow oscillation density appear to be specific to sleepwalking episodes rather than generalized to all sleep-wake transitions in sleepwalkers.

    Predictions allow for efficient human communication. To be efficient, listeners' predictions need to be adapted to the communicative context. Here we show that during speech processing this adaptation is a highly flexible and selective process that is able to fine-tune itself to individual language styles of specific interlocutors. In a newly developed paradigm, speakers differed in the probabilities by which they used particular sentence structures. Probe trials were applied to infer participants' syntactic expectations for a given speaker and to track changes of these expectations over time. The results show that listeners fine-tune their linguistic expectations according to the individual language style of a speaker. Strikingly, nine months after the initial experiment these highly specific expectations could be rapidly reactivated when confronted with the particular language style of a speaker but not merely on the basis of an association with speaker identity per se. These findings highlight that communicative interaction fine-tunes and consolidates interlocutor specific communicative predictions which can overrule strong linguistic priors.

    The influential framework of 'predictive processing' suggests that prior probabilistic expectations influence, or even constitute, perceptual contents. This notion is evidenced by the facilitation of low-level perceptual processing by expectations. However, whether expectations can facilitate high-level components of perception remains unclear. We addressed this question by considering the influence of expectations on perceptual metacognition. To isolate the effects of expectation from those of attention we used a novel factorial design: expectation was manipulated by changing the probability that a Gabor target would be presented; attention was manipulated by instructing participants to perform or ignore a concurrent visual search task. We found that, independently of attention, metacognition improved when yes/no responses were congruent with expectations of target presence/absence. Results were modeled under a novel Bayesian signal detection theoretic framework which integrates bottom-up signal propagation with top-down influences, to provide a unified description of the mechanisms underlying perceptual decision and metacognition.

    The caleosin genes encode proteins with a single conserved EF hand calcium-binding domain and comprise small gene families found in a wide range of plant species. Some members of the gene family have been shown to be upregulated by environmental stresses including low water availability and high salinity. Caleosin 3 from wheat has been shown to interact with the α-subunit of the heterotrimeric G proteins, and to act as a GTPase activating protein (GAP). This study characterizes the size and diversity of the gene family in wheat and related species and characterizes the differential tissue-specific expression of members of the gene family. A total of 34 gene family members that belong to eleven paralogous groups of caleosins were identified in the hexaploid bread wheat, T. aestivum. Each group was represented by three homeologous copies of the gene located on corresponding homeologous chromosomes, except the caleosin 10, which has four gene copies. Ten gene family members were identified in diploid barley, Hordeum vulgare, and in rye, Secale cereale, seven in Brachypodium distachyon, and six in rice, Oryza sativa. The analysis of gene expression was assayed in triticale and rye by RNA-Seq analysis of 454 sequence sets and members of the gene family were found to have diverse patterns of gene expression in the different tissues that were sampled in rye and in triticale, the hybrid hexaploid species derived from wheat and rye. Expression of the gene family in wheat and barley was also previously determined by microarray analysis, and changes in expression during development and in response to environmental stresses are presented. The caleosin gene family had a greater degree of expansion in the Triticeae than in the other monocot species, Brachypodium and rice. The prior implication of one member of the gene family in the stress response and heterotrimeric G protein signaling, points to the potential importance of the caleosin gene family.

    Full Text Available Abstract Background The CDC's Family History Public Health Initiative encourages adoption and increase awareness of family health history. To meet these goals and develop a personalized medicine implementation science research agenda, the Genomedical Connection is using an implementation research (T3 research framework to develop and integrate a self-administered computerized family history system with built-in decision support into 2 primary care clinics in North Carolina. Methods/Design The family health history system collects a three generation family history on 48 conditions and provides decision support (pedigree and tabular family history, provider recommendation report and patient summary report for 4 pilot conditions: breast cancer, ovarian cancer, colon cancer, and thrombosis. All adult English-speaking, non-adopted, patients scheduled for well-visits are invited to complete the family health system prior to their appointment. Decision support documents are entered into the medical record and available to provider's prior to the appointment. In order to optimize integration, components were piloted by stakeholders prior to and during implementation. Primary outcomes are change in appropriate testing for hereditary thrombophilia and screening for breast cancer, colon cancer, and ovarian cancer one year after study enrollment. Secondary outcomes include implementation measures related to the benefits and burdens of the family health system and its impact on clinic workflow, patients' risk perception, and intention to change health related behaviors. Outcomes are assessed through chart review, patient surveys at baseline and follow-up, and provider surveys. Clinical validity of the decision support is calculated by comparing its recommendations to those made by a genetic counselor reviewing the same pedigree; and clinical utility is demonstrated through reclassification rates and changes in appropriate screening (the primary outcome

    We examined exercise behaviors among family caregivers and the degree to which aspects of the caregiving role influenced exercise behaviors. Understanding factors associated with caregiver physical activity provides practitioners the means to design and tailor interventions to be effective for caregivers. Caregivers (N=208) participating in a self-care intervention to promote caregiving skills were surveyed at baseline, prior to training. Measures included caregiver characteristics, care recipient characteristics, attitudes and intentions toward exercise and levels of physical activity. Mental health variables and self-efficacy for exercise were significantly related to exercise levels in bivariate analyses. Regression analyses revealed that caregiver and care recipient characteristics accounted for a small percentage of the variance in exercise behavior. Caregiver vitality and self-efficacy for exercise were key variables most significantly related to exercise behaviors. Findings suggest that mental health factors and attitudes about exercise may be more important predictors of exercise than caregiving factors.

    The family medicine residency behavioral science curriculum is more effective if prioritized to match what is needed in practice after graduation. Two prior studies (Kendall, Marvel, & Cruickshank, 2003; Marvel & Major, 1999) identified physician priorities for behavioral science education. The present study extends this research to include topics from more recent curriculum guidelines and examines the extent to which size of community and perceived competence correlate with prioritization of Washington state family physicians. Practicing family physicians in Washington state (N = 2,270) were invited to complete the survey. Respondents provided demographic and practice information. Respondents then rated, on a scale from 1 to 4, 35 behavioral science topics on 2 different scales including (a) priority to be given in residency education and (b) perceived level of competence. A total of 486 responded and 430 completed both priority and competence scales for a response rate of 19%. The top half of 35 topics of the present study included the top 13 topics found in the 2 prior studies. Priority and competence scales were moderately correlated (r = .48, n = 430, p = .001). There was a small significant correlation with size of community and priority ratings (r = .13, n = 435, p = .006). Family physicians in Washington state prioritize behavioral science topics in residency education similar to Colorado and Mississippi. The results of this study support recent ACGME guidelines, in that training should focus on common psychiatric illnesses, including depression and anxiety, and interpersonal processes.

    Several theoretical and computational techniques are presented for compound failure models in which the failure rate or failure probability for a class of components is considered to be a random variable. Both the failure-on-demand and failure-rate situation are considered. Ten different prior families are presented for describing the variation or uncertainty of the failure parameter. Methods considered for estimating values for the prior parameters from a given set of failure data are (1) matching data moments to those of the prior distribution, (2) matching data moments to those of the compound marginal distribution, and (3) the marginal maximum likelihood method. Numerical methods for computing the parameter estimators for all ten prior families are presented, as well as methods for obtaining estimates of the variances and covariance of the parameter estimators, it is shown that various confidence, probability, and tolerance intervals can be evaluated. Finally, to test the resulting failure models against the given failure data, generalized chi-squage and Kolmogorov-Smirnov goodness-of-fit tests are proposed together with a test to eliminate outliers from the failure data. Computer codes based on the results presented here have been prepared and are presented in a companion report

    We use the Immigrants Admitted to the United States (micro-data) supplemented with special tabulations from the Department of Homeland Security to examine how family reunification impacts the age composition of new immigrant cohorts since 1980. We develop a family migration multiplier measure for the period 1981 to 2009 that improves on prior studies by including immigrants granted legal status under the 1986 Immigration Reform and Control Act and relaxing unrealistic assumptions required by synthetic cohort measures. Results show that every 100 initiating immigrants admitted between 1981-85 sponsored an average of 260 family members; the comparable figure for initiating immigrants for the 1996-2000 cohort is 345 family members. Furthermore, the number of family migrants ages 50 and over rose from 44 to 74 per 100 initiating migrants. The discussion considers the health and welfare implications of late-age immigration in a climate of growing fiscal restraint and an aging native population.

    Parental educational involvement in primary and secondary school is strongly linked to students' academic success; however; less is known about the long-term effects of parental involvement. In this study, we investigated the associations between four aspects of parents' educational involvement (i.e., home- and school-based involvement, educational expectations, academic advice) and young people's proximal (i.e., grades) and distal academic outcomes (i.e., educational attainment). Attention was also placed on whether these relations varied as a function of family socioeconomic status or adolescents' prior achievement. The data were drawn from 15,240 10th grade students (50 % females; 57 % White, 13 % African American, 15 % Latino, 9 % Asian American, and 6 % other race/ethnicity) participating in the Education Longitudinal Study of 2002. We observed significant links between both school-based involvement and parental educational expectations and adolescents' cumulative high school grades and educational attainment. Moderation analyses revealed that school-based involvement seemed to be particularly beneficial for more disadvantaged youth (i.e., those from low-SES families, those with poorer prior achievement), whereas parents' academic socialization seemed to better promote the academic success of more advantaged youth (i.e., those from high-SES families, those with higher prior achievement). These findings suggest that academic interventions and supports could be carefully targeted to better support the educational success of all young people.

    The aim of this paper is to present a hermeneutic phenomenological study illuminating patients' existential situation prior to colorectal surgery. The intention was also to explore the value of the encounter between patient and nurse. Patients waiting for major surgery experience multifarious reactions. Emotions of anxiety, fears of the unknown, anaesthesia, cancer diagnosis and death can arise. Several earlier studies have reported the importance of information, coping strategies and the need to reduce anxiety and stress in relation to surgery. However, there is a lack of studies focusing on patients' existential situation in the preoperative phase. Conversational interviews were conducted with 28 patients 1 week before their surgery during autumn 2002. Analysis of the data was influenced by van Manen's existential themes: lived space/spatiality, lived body/corporeality, lived time/temporality and lived relation/relationality. Participants expressed either hope of increased spatiality or fear of restricted spatiality, according to whether they had a benign or malign diagnosis. Statements about lived time were also related to the diagnosis. Patients waiting for surgery for a benign diagnosis could use the time to relax and gather energy, while malignancy gave them high levels of anxiety and stress. Lived body experiences showed the ambivalence felt in entrusting one's body to professionals. Statements about lived relations drew attention to the need for considerate caregivers to enhance feelings of security and continuity. The existential situation of patients in a preoperative context was shown to be a state of uncertainty with regard to lived space, body, time and relation. The significance of meeting and talking to the nurse did not appear in the statements. The nurse was invisible. If nurses were to employ the existential themes proposed by van Manen in preoperative encounter with patients, their need for care might be more clearly identified and affirmed.

    Full Text Available One way to explore how prior sensory and motor events impact eye movements is to ask someone to look to targets located about a central point, returning gaze to the central point after each eye movement. Concerned about the contribution of this return to centre movement, Anderson et al. (2008 used a sequential saccade paradigm in which participants made a continuous series of saccades to peripheral targets that appeared to the left or right of the currently fixated location in a random sequence (the next eye movement began from the last target location. Examining the effects of previous saccades (n-x on current saccade latency (n, they found that saccadic reaction times (RT were reduced when the direction of the current saccade matched that of a preceding saccade (e.g. two left saccades, even when the two saccades in question were separated by multiple saccades in any direction. We examined if this pattern extends to conditions in which targets appear inside continuously marked locations that provide stable visual features (i.e. target ‘placeholders’ and when saccades are prompted by central arrows. Participants completed 3 conditions: peripheral targets (PT; continuous, sequential saccades to peripherally presented targets without placeholders; PT with placeholders; and centrally presented arrows (CA; left or right pointing arrows at the currently fixated location instructing participants to saccade to the left or right. We found reduced saccadic RT when the immediately preceding saccade (n-1 was in the same (vs. opposite direction in the PT without placeholders and CA conditions. This effect varied when considering the effect of the previous 2-5 (n-x saccades on current saccade latency (n. The effects of previous eye movements on current saccade latency may be determined by multiple, time-varying mechanisms related to sensory (i.e., retinotopic location, motor (i.e., saccade direction, and environmental (i.e., persistent visual objects

    The recently proposed sparse shape composition (SSC) opens a new avenue for shape prior modeling. Instead of assuming any parametric model of shape statistics, SSC incorporates shape priors on-the-fly by approximating a shape instance (usually derived from appearance cues) by a sparse combination of shapes in a training repository. Theoretically, one can increase the modeling capability of SSC by including as many training shapes in the repository. However, this strategy confronts two limitations in practice. First, since SSC involves an iterative sparse optimization at run-time, the more shape instances contained in the repository, the less run-time efficiency SSC has. Therefore, a compact and informative shape dictionary is preferred to a large shape repository. Second, in medical imaging applications, training shapes seldom come in one batch. It is very time consuming and sometimes infeasible to reconstruct the shape dictionary every time new training shapes appear. In this paper, we propose an online learning method to address these two limitations. Our method starts from constructing an initial shape dictionary using the K-SVD algorithm. When new training shapes come, instead of re-constructing the dictionary from the ground up, we update the existing one using a block-coordinates descent approach. Using the dynamically updated dictionary, sparse shape composition can be gracefully scaled up to model shape priors from a large number of training shapes without sacrificing run-time efficiency. Our method is validated on lung localization in X-Ray and cardiac segmentation in MRI time series. Compared to the original SSC, it shows comparable performance while being significantly more efficient.

    Certain contraceptive methods may increase the risk of adverse events for women with certain medical conditions, including some women with diabetes, hyperlipidemia, liver disease, cervical cancer, sexually transmitted infections (STIs) or human immunodeficiency virus (HIV). This review was conducted to evaluate the evidence regarding health outcomes among women with and without laboratory testing to identify certain medical conditions prior to initiating contraceptives. The PubMed database was searched from database inception through April 2012 for all peer-reviewed articles in any language evaluating health outcomes among women who initiated certain contraceptive methods and who had or had not received glucose, lipid, liver enzyme, cervical cytology, STI or HIV screening. The systematic review did not identify any relevant direct evidence. While certain methods of hormonal contraception may not be safe for use by some women with diabetes, hyperlipidemia or liver disease, there is little value in screening for these conditions in asymptomatic women prior to initiation of contraceptive methods due to the low prevalence of these conditions among women of reproductive age. Although intrauterine devices (IUDs) and cervical caps should not be initiated in women with cervical cancer, the high rates of cervical screening and low incidence of cervical cancer in the United States make this scenario unlikely. Although some women at risk for, or infected with, STIs or HIV should not undergo IUD insertion, if women have been screened for STIs or HIV according to guidelines, additional screening at the time of IUD insertion is not warranted. Requiring unnecessary laboratory screening prior to initiation of contraceptive methods may impose barriers to contraceptive access, and efforts to remove such barriers are critical in reducing unintended pregnancy.

    Full Text Available Research in child and adult literacy demonstrates that the achievement and the level of literacy that children attain at school is connected with the social and cultural characteristics and the level of literacy of the child's family. This intergenerational transfer of the level of literacy has motivated the search for different ways of improving the level of literacy.The concept of family literacy is based on the assumption that a higher level of parent literacy means that the children may achieve the same, and it also offers better schooling prospects. Family literacy programmes help fami­lies to develop different activities, in­cluding reading and writing skills, both in their community and in everyday life.

The action research methodology included a literature search to review the data on family violence education programmes and evidence-based family violence screening tools. Six education sessions were then developed and held for physicians at the Community Paediatric and Child Health Service (CPCHS). An audit was performed on the charts of all new referrals to the CPCHS for a period of 18 months prior to the education sessions and 5 months following the education sessions. A questionnaire was distributed at the first and final education sessions to gauge physician comfort with enquiry into family violence. The documented rate of enquiry into family violence at CPCHS was 24% in the retrospective chart audit. Following the series of education sessions, the documented rate of enquiry increased to 60% (P family violence also increased from 13% of all new patients in the retrospective chart audit to 24% in the prospective arm of the study (P family violence and were comfortable enquiring about family violence.

    Because organ transplantation relies on public support for donation, an analysis of public discourse around organ donation is essential. We investigated the portrayal of family veto - when a family overrides the deceased person's prior legally executed wishes to donate - in Canadian news media. Using the Canadian Newsstream database, we identified articles published in English-language newspapers addressing family veto between 2000 and 2016. Guided by the theoretical perspectives of framing of media effects, we conducted a systematic content analysis of the articles to examine how the Canadian media framed family veto. An initial in-depth analysis of the data set in which themes and patterns were captured and recorded identified coding categories, including primary framing of family veto, prevalence, reasons, ethical or legal concerns and overall tone of the article. Two coders analyzed the data set to ensure intercoder reliability. A total of 133 relevant articles were identified. Family veto was framed predominantly as something that should not be allowed (81 articles [60.9%]) and as a reality that is little understood outside the transplantation community (45 [33.8%]). One-quarter of the articles (32 [24.1%]) highlighted ethical principles of autonomy and justice associated with family veto. Family veto was represented as a stumbling block in the present organ donation system, with most publications (107 [80.4%]) calling for change. There were differing interpretations of organ donation legislation, with 82 articles (61.6%) erroneously stating or suggesting that existing legislation permits family veto. Family veto in organ donation was portrayed predominantly negatively. Many publications reflected a misunderstanding of the law concerning this issue. Although the framing of family veto highlighted important ethical and legal concerns as well as practice and policy considerations, research is needed to enhance the understanding of family veto in organ donation

  3. Prior Sensitivity Analysis in Default Bayesian Structural Equation Modeling.

    2017-11-27

    Bayesian structural equation modeling (BSEM) has recently gained popularity because it enables researchers to fit complex models and solve some of the issues often encountered in classical maximum likelihood estimation, such as nonconvergence and inadmissible solutions. An important component of any Bayesian analysis is the prior distribution of the unknown model parameters. Often, researchers rely on default priors, which are constructed in an automatic fashion without requiring substantive prior information. However, the prior can have a serious influence on the estimation of the model parameters, which affects the mean squared error, bias, coverage rates, and quantiles of the estimates. In this article, we investigate the performance of three different default priors: noninformative improper priors, vague proper priors, and empirical Bayes priors-with the latter being novel in the BSEM literature. Based on a simulation study, we find that these three default BSEM methods may perform very differently, especially with small samples. A careful prior sensitivity analysis is therefore needed when performing a default BSEM analysis. For this purpose, we provide a practical step-by-step guide for practitioners to conducting a prior sensitivity analysis in default BSEM. Our recommendations are illustrated using a well-known case study from the structural equation modeling literature, and all code for conducting the prior sensitivity analysis is available in the online supplemental materials.

    Full Text Available Abstract Background One of the challenges of bioinformatics remains the recognition of short signal sequences in genomic DNA such as donor or acceptor splice sites, splicing enhancers or silencers, translation initiation sites, transcription start sites, transcription factor binding sites, nucleosome binding sites, miRNA binding sites, or insulator binding sites. During the last decade, a wealth of algorithms for the recognition of such DNA sequences has been developed and compared with the goal of improving their performance and to deepen our understanding of the underlying cellular processes. Most of these algorithms are based on statistical models belonging to the family of Markov random fields such as position weight matrix models, weight array matrix models, Markov models of higher order, or moral Bayesian networks. While in many comparative studies different learning principles or different statistical models have been compared, the influence of choosing different prior distributions for the model parameters when using different learning principles has been overlooked, and possibly lead to questionable conclusions. Results With the goal of allowing direct comparisons of different learning principles for models from the family of Markov random fields based on the same a-priori information, we derive a generalization of the commonly-used product-Dirichlet prior. We find that the derived prior behaves like a Gaussian prior close to the maximum and like a Laplace prior in the far tails. In two case studies, we illustrate the utility of the derived prior for a direct comparison of different learning principles with different models for the recognition of binding sites of the transcription factor Sp1 and human donor splice sites. Conclusions We find that comparisons of different learning principles using the same a-priori information can lead to conclusions different from those of previous studies in which the effect resulting from different

    Full Text Available CONTEXTO: Dentre as maiores causas de internamento hospitalar em pacientes com diabetes melito tipos 1 e 2 estão as complicações do pé diabético, principalmente pelas sequelas, muitas vezes incapacitantes, destacando-se as amputações de membros inferiores. A insuficiência vascular periférica ocorre mais precocemente nesses pacientes. A coexistência de neuropatia, isquemia e imunodeficiência favorece o desenvolvimento de infecções nos membros inferiores, que, se não tratadas adequadamente, podem levar a amputações e até à morte. OBJETIVOS: Comparar os fatores de risco para amputações maiores e menores em pacientes diabéticos de um Programa de Saúde da Família do CAIC Virgem dos Pobres III, em Maceió, AL. MÉTODOS: Foram examinados 93 pacientes com o diagnóstico de diabetes melito, sendo avaliada a realização ou não de amputações de membros inferiores. As variáveis analisadas foram: sexo, idade, tipo do diabetes, pressão arterial, amputação prévia (se maior ou menor, alterações dermatológicas, alterações de pulsos arteriais pedioso e tibial posterior, deformidades e neuropatia, e foram classificadas de acordo com a classificação de Wagner e de Texas. RESULTADOS: Todos os pacientes eram diabéticos tipo 2. Verificou-se que 4,30% dos pacientes evoluíram para amputação de membros inferiores. Não se observou variação significativa da hipertensão, deformidades e neuropatia em relação ao grupo de pacientes que foram amputados. Entretanto, a ausência de detecção dos pulsos distais dos membros inferiores revelou-se bastante significativa com relação ao desfecho de amputação. CONCLUSÃO: Deve-se proporcionar aos diabéticos um atendimento ambulatorial adequado para que seja possível prevenir ou minimizar tais complicações.BACKGROUND: The main causes of hospital admission in patients with type 1 and 2 diabetes mellitus include diabetic foot complications, which may result in particularly disabling

    Individuals with first-episode psychosis, like those with chronic psychotic disorders, are at elevated risk for suicidal ideation and suicide attempts. However, relatively little is known about suicidality among first-episode patients prior to their initial presentation for treatment. This analysis was designed as a US-based examination of recent findings on prior suicide attempts from Dublin, Ireland, here focusing on prevalence and correlates of suicidal ideation during the weeks prior to initial treatment-seeking. Participants included 109 first-episode inpatients with primary psychotic disorders in public-sector settings that serve an urban, low-income, socially disadvantaged, predominantly African American population. Eligible patients had received 3 months prior to the index admission, though most were completely treatment naïve. Assessments included the Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, Birchwood Insight Scale, and a rigorous method for determining age at onset of first psychotic symptoms and duration of untreated psychosis. Disconcertingly, nearly one quarter of patients (23%) endorsed a history of suicidal ideation in the 2 weeks prior to first admission. In the model designed to replicate the prior study in Ireland, Calgary Depression score (calculated omitting hopelessness and suicidal ideation as these were separate variables in the analysis) was a predictor of suicidal ideation (P suicidal ideation. Findings suggest that depression, insight, and suicidality should be carefully monitored among first-episode patients initiating treatment and during the early course of illness. As insight improves, coping strategies should be enhanced with a goal of minimizing depression and preventing suicidality. © 2011 Blackwell Publishing Asia Pty Ltd.

    2009-06-01

    To explore the views of the Western Australian community on cascade screening for familial hypercholesterolemia (FH), focusing on the desire of relatives to be informed about a familial risk, the acceptability of being informed by family or by health professionals, and preferences around how this information is shared. A cross-sectional computer assisted telephone interviewing (CATI) survey was employed, and 430 respondents were recruited randomly from the electronic version of the Western Australian telephone directory. Interviews were conducted in June 2008 and had a response rate of 75%. Most respondents (93%) indicated a desire to be informed about their familial risk of FH. Of these, 91% desired to be informed by their relative, 77% by the health clinic involved in the FH screening program, and 95% indicated a desire to be offered screening for the condition. Women aged 18-54 years were more likely to report a preference for being informed by their relative. The odds of reporting a high likelihood of attending the program health clinic for testing were significantly lower among men aged 18-54 years. If contacted by the program health clinic, 1 in 3 respondents found it unacceptable to not be told their relative's name. This study provides evidence of community support for FH cascade screening programs that adopt a policy of "direct contact," where program staff contact the relatives of the index cases and inform them of their familial risk. Maximizing community support for the screening program may require that index cases give consent to include their personal details when the initial contact is made with their relatives. It may also require special consideration of how younger members of the community are contacted and encouraged to participate in the screening programs.

    1985-01-01

    This chapter deals with the radiotherapy and cytotoxic chemotherapy of the malignant lymphomas. Included within this group are Hodgkin's disease, non-Hodgkin's lymphoma, mycosis fungoides, and chronic lymphatic leukaemia. A further section deals with the myeloproliferative disorders, including granulocytic leukaemia, polycythaemia vera, and primary thrombocythaemia. Excluded are myeloma and reticulum cell sarcoma of bone and acute leukaemia. With regard to Hodgkin's disease, the past 25 years have seen general recognition of the curative potential of radiotherapy, at least in the local stages, and, more recently, awareness of the ability to achieve long-term survival after combination chemotherapy in generalised or in recurrent disease. At the same time the importance of staging has become appreciated and the introduction of procedures such as lymphography, staging laparotomy, and computer tomography (CT) has enormously increased its reliability. Advances have not been so dramatic in the complex group of non-Hodgkins's lymphomas, but are still very real

    The grand unified theories (GUT) of the simple Lie groups including extra Z bosons are discussed. Under authors's hypothesis there are only SU 5+m SO 6+4n and E 6 groups. The general discussion of SU 5+m is given, then the SU 6 and SU 7 are considered. In SU 6 the 15+6 * +6 * fermion representations are used, which are not same as others in fermion content, Yukawa coupling and broken scales. A conception of clans of particles, which are not families, is suggested. These clans consist of extra Z bosons and the corresponding fermions of the scale. The all of fermions in the clans are down quarks except for the standard model which consists of Z bosons and 15 fermions, therefore, the spectrum of the hadrons which are composed of these down quarks are different from hadrons at present

    2018-02-01

    Previous research has found that family problem-solving interactions are more constructive and less contentious when there is a family member with bipolar disorder compared with schizophrenia. The present study extended this research by examining whether family problem-solving interactions differ between clinical high-risk (CHR) stages of each illness. Trained coders applied a behavioral coding system (O'Brien et al., 2014) to problem-solving interactions of parents and their adolescent child, conducted just prior to beginning a randomized trial of family-focused therapy. The CHR for psychosis sample included 58 families with an adolescent with attenuated positive symptoms, brief intermittent psychosis, or genetic risk and functional deterioration; the CHR for bipolar disorder sample included 44 families with an adolescent with "unspecified" bipolar disorder or major depressive disorder and at least one first or second degree relative with bipolar I or II disorder. When controlling for adolescent gender, age, functioning, and parent education, mothers of youth at CHR for psychosis displayed significantly more conflictual and less constructive communication than did mothers of youth at CHR for bipolar disorder. Youth risk classification did not have a significant relationship with youths' or fathers' communication behavior. The family environment among help-seeking adolescents may be more challenging for families with an adolescent at CHR for psychosis compared with bipolar illness. Accordingly, families of adolescents at clinical high-risk for psychosis may benefit from more intensive or focused communication training than is required by families of adolescents at clinical high-risk for bipolar disorder or other mood disorders.

    Research has shown the positive associations of family meals and diet quality. However, little is known about how other meals/snacks may be associated with family meals. The purpose was to determine the associations among the frequency and calorie consumption of meals/snacks and family dinners. Cross-sectional. Data were collected using Web-based Eating Behaviour Questionnaire (WEB-Q), including a 24-h diet recall for breakfast, morning snack, lunch, afternoon snack, dinner, and evening snack. Measured height and weight were used to determine body weight status (BMI). Participants included 1068 grade 7 students (52% males) from 26 schools in Windsor Essex County, Ontario, Canada. Meal, snack, and total daily caloric intake; meal and snack frequency; with whom dinner was consumed, and weekly family dinner frequency. Exploratory one-way ANOVAs and chi-square tests; nominal and ordinal logistic regression. Ninety-three percent of participants consumed dinner with family members on the night prior to the survey and 77% reported usually consuming dinner/supper with at least one parent on six to seven nights/week. Those who had dinner with family members consumed 4.88 (SD 1.1) meals/snacks per day compared with 4.40 (SD 1.3) and 4.40 (SD 1.3) times/day for consuming dinner alone or with friends, respectively (p=0.006). On the day prior to the survey, participants were less likely to consume a family meal if they consumed a lower number of meals and snacks per day (OR=0.69 (95% CI: 0.55, 0.87), psnacks per day (OR=0.84 (95% CI: 0.74, 0.96), p=0.009). While specific meals and snacks were not associated with family dinner, overall eating frequency was positively associated with family meals. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Stroke in midlife is a life altering, challenging experience for the whole family thereby necessitating a family approach to intervention. The aim of this study was to describe the experiences of 17 family members living in Sweden, including seven adult stroke patients (six males; one female) under the age of 65 who participated in a series of three nurse-led family conversations that were offered in each family's home. These Family Health Conversations (FamHC) were guided by the conceptual lens of Family System Nursing. Individual, semi-structured, evaluative interviews conducted with each participant one month after the FamHC were analyzed by qualitative content analysis. The FamHC were described by family members as a unique conversation that they had not previously experienced in health care contexts. Family members described possibilities for relational sharing and meaningful conversations as well as changes in family functioning that support the suitability of FamHC for family stroke care. © The Author(s) 2016.

    This paper examines differences between early- and late-onset injection drug users (12-16 years versus 17-24 years) in terms of the antecedents and circumstances of first injection. Cross-sectional retrospective design, using logistic regression. Setting Australia: Sydney, Brisbane, rural New South Wales. A total of 336 injection drug users aged 16-25 years at the time of interview. Independent variables included family injection drug use, homelessness and other demographic variables, drugs used prior to the first injection, length of pre-injection drug career, behaviours at time of first injection (e.g. drug injected, reasons/motives for the first injection, risk behaviours). Early-onset injection was associated independently with: having a family who injected drugs, having left school early, an unreliable source of income, a short pre-injection drug career, planning of the first injection, reliance on others for administration of the first injection and denial that experimentation was the motive for the first injection. In bivariate analysis, early-onset injection was associated further with: homelessness, being an Indigenous Australian, omission of use of certain pre-injection drugs, group presence at first injection, reliance on others for acquisition of the first needle and syringe and having injected the first time because an injection was offered. The research shows that early-onset, compared with late-onset injectors, are more likely to have an immediate family who inject drugs and other problematic beginnings in early life. They have an accelerated transition to injection, and differences in autonomy and motivation at first injection. These characteristics may make them more vulnerable to risk taking.

  2. On selecting a prior for the precision parameter of Dirichlet process mixture models

    Dorazio, R.M.

    2009-01-01

    In hierarchical mixture models the Dirichlet process is used to specify latent patterns of heterogeneity, particularly when the distribution of latent parameters is thought to be clustered (multimodal). The parameters of a Dirichlet process include a precision parameter ?? and a base probability measure G0. In problems where ?? is unknown and must be estimated, inferences about the level of clustering can be sensitive to the choice of prior assumed for ??. In this paper an approach is developed for computing a prior for the precision parameter ?? that can be used in the presence or absence of prior information about the level of clustering. This approach is illustrated in an analysis of counts of stream fishes. The results of this fully Bayesian analysis are compared with an empirical Bayes analysis of the same data and with a Bayesian analysis based on an alternative commonly used prior.

    We performed computer simulations to study the effects of prior infection on vaccine efficacy. We injected three antigens sequentially. The first antigen, designated the prior, represented a prior infection or vaccination. The second antigen, the vaccine, represented a single component of the trivalent influenza vaccine. The third antigen, the epidemic, represented challenge by an epidemic strain. For a fixed vaccine to epidemic strain cross-reactivities to the vaccine and to the epidemic strains. We found that, for many cross-reactivities, vaccination, when it had been preceded by a prior infection, provided more protection than vaccination alone. However, at some cross-reactivities, the prior infection reduced protection by clearing the vaccine before it had the chance to produce protective memory. The cross-reactivities between the prior, vaccine and epidemic strains played a major role in determining vaccine efficacy. This work has applications to understanding vaccination against viruses such as influenza that are continually mutating.

    To assess the degree of caregiver burden and family functioning among Taiwanese primary family caregivers of people with schizophrenia and to test its association with demographic characteristics, family demands, sense of coherence and family hardiness. Family caregiving is a great concern in mental illness. Yet, the correlates of caregiver burden and family functioning in primary family caregivers of individuals with schizophrenia still remain unclear. A cross-sectional descriptive study. A convenience sample of 137 primary family caregivers was recruited from two psychiatric outpatient clinics in Taiwan. Measures included a demographic information sheet and the Chinese versions of the Family Stressors Index, Family Strains Index, 13-item Sense of Coherence Scale, 18-item Caregiver Burden Scale, Family Hardiness Index and Family Adaptability, Partnership, Growth, Affection, and Resolve Index. Data analysis included descriptive statistics, Pearson's product-moment correlation coefficients, t-test, one-way analysis of variance and a stepwise multiple linear regression. Female caregivers, additional dependent relatives, increased family demands and decreased sense of coherence significantly increased caregiver burden, whereas siblings as caregivers reported lower degrees of burden than parental caregivers. Family caregivers with lower family demands, increased family hardiness and higher educational level had significantly enhanced family functioning. Sense of coherence was significantly correlated with family hardiness. Our findings highlighted the importance of sense of coherence and family hardiness in individual and family adaptation. Special attention needs to focus on therapeutic interventions that enhance sense of coherence and family hardiness, thereby improving the perception of burden of care and family functioning. Given the nature of family caregiving in schizophrenia, understanding of correlates of caregiver burden and family functioning would help

    2016-03-01

    Full Text Available Purpose: Urosepsis is the most feared complication of transrectal prostate biopsy. The incidence may be increasing from <1% to 2%–3% in contemporary series. Historically, fluoroquinolones have been effective antibiotic prophylaxis to prevent infective complications but antibiotic resistance is increasing. The increase in antibiotic resistance may contribute to reported increases in urosepsis and hospitalization after transrectal biopsy. This article will review other methods clinicians may employ to reduce the incidence of infective complications after prostate biopsy. Materials and Methods: A systematic review of the literature was conducted using literature databases PubMed and Ovid MEDLINE in August 2015 in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria. Results: Effective strategies to reduce infective complications after transrectal prostate biopsy include augmented prophylaxis with other antibiotics, rectal swab culture directed antibiotic prophylaxis or a transperineal biopsy approach. Needle disinfection, minimizing the number of biopsy needles and rectal disinfectants may also be of use. These methods may be of particular utility in patients with risk factors for developing urosepsis such as recent antibiotic use and overseas travel. Conclusions: The scientific literature describes various techniques designed to reduce infective complications caused by prostate biopsy. Clinicians should consider incorporating these novel techniques into their contemporary practice.

  13. Quantitative utilization of prior biological knowledge in the Bayesian network modeling of gene expression data

    2011-08-01

    Full Text Available Abstract Background Bayesian Network (BN is a powerful approach to reconstructing genetic regulatory networks from gene expression data. However, expression data by itself suffers from high noise and lack of power. Incorporating prior biological knowledge can improve the performance. As each type of prior knowledge on its own may be incomplete or limited by quality issues, integrating multiple sources of prior knowledge to utilize their consensus is desirable. Results We introduce a new method to incorporate the quantitative information from multiple sources of prior knowledge. It first uses the Naïve Bayesian classifier to assess the likelihood of functional linkage between gene pairs based on prior knowledge. In this study we included cocitation in PubMed and schematic similarity in Gene Ontology annotation. A candidate network edge reservoir is then created in which the copy number of each edge is proportional to the estimated likelihood of linkage between the two corresponding genes. In network simulation the Markov Chain Monte Carlo sampling algorithm is adopted, and samples from this reservoir at each iteration to generate new candidate networks. We evaluated the new algorithm using both simulated and real gene expression data including that from a yeast cell cycle and a mouse pancreas development/growth study. Incorporating prior knowledge led to a ~2 fold increase in the number of known transcription regulations recovered, without significant change in false positive rate. In contrast, without the prior knowledge BN modeling is not always better than a random selection, demonstrating the necessity in network modeling to supplement the gene expression data with additional information. Conclusion our new development provides a statistical means to utilize the quantitative information in prior biological knowledge in the BN modeling of gene expression data, which significantly improves the performance.

    A forward-looking long-term policy of employment-based family planning and employee health has paid off in lower birth rates, better health indicators as well as significant savings in insurance and medical benefits expenses for Nippon Express Co., Ltd., Japan. Nippon Express is now an international corporation with 48,00 employees. "Nittsu" as it is known, began a family planning program in 1956 by hiring qualified professional family planning nurses and midwives, producing its own educational materials and selling contraceptives at reduced rates. The family planning program was expanded to the extent that it has its own Managing Council with Local Councils run democratically, users employees and their spouses as volunteers with group guidance, and provides services at community health centers in rural areas. Now there are 63,000 households covered, activities encompass recreation and home economics, and the health focus has broadened to family health and to include risk factors for disease of middle age. The program has reduced the birth rate of employees from 19.5% to 8.2%, and the abortion rate to 1/10 the initial level, cut the dependency rate of the work force 50%, lowered absenteeism by 2/3, accidents to 1/10, and improved employee loyalty and morale.

  18. Prior knowledge in recalling arguments in bioethical dilemmas

    2015-09-01

    Full Text Available Prior knowledge is known to facilitate learning new information. Normally in studies confirming this outcome the relationship between prior knowledge and the topic to be learned is obvious: the information to be acquired is part of the domain or topic to which the prior knowledge belongs. This raises the question as to whether prior knowledge of various domains facilitates recalling information. In this study 79 eleventh-grade students completed a questionnaire on their prior knowledge of seven different domains related to the bioethical dilemma of prenatal diagnostics. The students read a text containing arguments for and arguments against prenatal diagnostics. After one week and again 12 weeks later they were asked to write down all the arguments they remembered. Prior knowledge helped them recall the arguments one week (r = .350 and 12 weeks (r = .316 later. Prior knowledge of three of the seven domains significantly helped them recall the arguments one week later (correlations between r = .194 to r = .394. Partial correlations with interest as a control item revealed that interest did not explain the relationship between prior knowledge and recall. Prior knowledge of different domains jointly supports the recall of arguments related to bioethical topics.

  19. Chromosomal differences between acute nonlymphocytic leukemia in patients with prior solid tumors and prior hematologic malignancies. A study of 14 cases with prior breast cancer

    1989-01-01

    A cytogenetic study of 14 patients with secondary acute nonlymphocytic leukemia (S-ANLL) with prior treatment for breast cancer is reported. The chromosomes recurrently involved in numerical or structural anomalies are chromosomes 7, 5, 17, and 11, in decreasing order of frequency. The distribution of the anomalies detected in this sample of patients is similar to that observed in published cases with prior breast or other solid tumors, though anomalies of chromosome 11 were not pointed out, but it significantly differs from that of the S-ANLL with prior hematologic malignancies. This difference is principally due to a higher involvement of chromosome 7 in patients with prior hematologic malignancies and of chromosomes 11 and 17 in patients with prior solid tumors. A genetic determinism involving abnormal recessive alleles located on chromosomes 5, 7, 11, and 17 uncovered by deletions of the normal homologs may be a cause of S-ANLL. The difference between patients with prior hematologic malignancies or solid tumors may be explained by different constitutional mutations of recessive genes in the two groups of patients

    For many, family therapy refers to sessions in which all family members are present. Yet in contemporary psychiatry there are many ways to work with families in addition to this classic concept. This article proposes family intervention as an encompassing term for a new family paradigm in child and adolescent psychiatry. Developmental psychopathology is a guiding principle of this paradigm. A full range of ways to work with families clinically is described with clinical examples. Copyright © 2015 Elsevier Inc. All rights reserved.

    To undertake a review of the quantitative research literature, to determine emergency staff and public attitudes, to support the implementation and practice of family presence during resuscitation in the emergency department. FPDR although endorsed by numerous resuscitation councils, cardiac, trauma and emergency associations, continues to be topical, the extent to which it is implemented and practiced remains unclear. A review of the quantitative studies published between 1992 and October 2011 was undertaken using the following databases: CINAHL, Ovid Medline, PSYCHINFO, Pro-Quest, Theses Database, Cochrane, and Google Scholar search engine. The primary search terms were 'family presence', and 'resuscitation'. The final studies included in this paper were appraised using the Critical Appraisal Skills Programme criteria. Fourteen studies were included in this literature review. These included quantitative descriptive designs, pre and post-test designs and one randomized controlled trial (RCT). The studies were divided into three main research areas; investigation of emergency staff attitudes and opinions, family and general public attitudes, and four papers evaluating family presence programs in the emergency department. Studies published prior to 2000 were included in the background. FPDR in the emergency department is well recognised and documented among policy makers, the extent in which it is implemented and practiced remains unclear. Further research is needed to assess how emergency staff are educated and trained in order to facilitate family presence during resuscitation attempts. Copyright © 2012. Published by Elsevier Ltd.

  3. Where are family theories in family-based obesity treatment?: conceptualizing the study of families in pediatric weight management

    Science.gov (United States)

    Skelton, JA; Buehler, C; Irby, MB; Grzywacz, JG

    2014-01-01

    Family-based approaches to pediatric obesity treatment are considered the ‘gold-standard,’ and are recommended for facilitating behavior change to improve child weight status and health. If family-based approaches are to be truly rooted in the family, clinicians and researchers must consider family process and function in designing effective interventions. To bring a better understanding of family complexities to family-based treatment, two relevant reviews were conducted and are presented: (1) a review of prominent and established theories of the family that may provide a more comprehensive and in-depth approach for addressing pediatric obesity; and (2) a systematic review of the literature to identify the use of prominent family theories in pediatric obesity research, which found little use of theories in intervention studies. Overlapping concepts across theories include: families are a system, with interdependence of units; the idea that families are goal-directed and seek balance; and the physical and social environment imposes demands on families. Family-focused theories provide valuable insight into the complexities of families. Increased use of these theories in both research and practice may identify key leverage points in family process and function to prevent the development of or more effectively treat obesity. The field of family studies provides an innovative approach to the difficult problem of pediatric obesity, building on the long-established approach of family-based treatment. PMID:22531090

    This article explores the factor structure of a new family satisfaction with nursing home care instrument and determines the relationship of resident quality of life (QOL) and facility characteristics with family satisfaction. Data sources include (1) family satisfaction interviews ( n = 16,790 family members), (2) multidimensional survey of resident QOL ( n = 13,433 residents), and (3) facility characteristics ( n = 376 facilities). We used factor analysis to identify domains of family satisfaction and multivariate analyses to identify the role of facility-level characteristics and resident QOL on facility-mean values of family satisfaction. Four distinct domains were identified for family satisfaction: "care," "staff," "environment," and "food." Chain affiliation, higher resident acuity, more deficiencies, and large size were all associated with less family satisfaction, and resident QOL was a significant (albeit weak) predictor of family satisfaction. Results suggest that family member satisfaction is distinct from resident QOL but is associated with resident QOL and facility characteristics.

  5. Construction and test of the PRIOR proton microscope; Aufbau und Test des Protonenmikroskops PRIOR

    Energy Technology Data Exchange (ETDEWEB)

    Lang, Philipp-Michael

    2015-01-15

    The study of High Energy Density Matter (HEDM) in the laboratory makes great demands on the diagnostics because these states can usually only be created for a short time and usual diagnostic techniques with visible light or X-rays come to their limit because of the high density. The high energy proton radiography technique that was developed in the 1990s at the Los Alamos National Laboratory is a very promising possibility to overcome those limits so that one can measure the density of HEDM with high spatial and time resolution. For this purpose the proton microscope PRIOR (Proton Radiography for FAIR) was set up at GSI, which not only reproduces the image, but also magnifies it by a factor of 4.2 and thereby penetrates matter with a density up to 20 g/cm{sup 2}. Straightaway a spatial resolution of less than 30 μm and a time resolution on the nanosecond scale was achieved. This work describes details to the principle, design and construction of the proton microscope as well as first measurements and simulations of essential components like magnetic lenses, a collimator and a scintillator screen. For the latter one it was possible to show that plastic scintillators can be used as converter as an alternative to the slower but more radiation resistant crystals, so that it is possible to reach a time resolution of 10 ns. Moreover the characteristics were investigated for the system at the commissioning in April 2014. Also the changes in the magnetic field due to radiation damage were studied. Besides that an overview about future applications is given. First experiments with Warm Dense Matter created by using a Pulsed Power Setup have already been performed. Furthermore the promising concept of combining proton radiography with particle therapy has been investigated in context of the PaNTERA project. An outlook on the possibilities with future experiments at the FAIR accelerator facility is given as well. Because of higher beam intensity an energy one can expect even

    female-headed families than for married-couple families. The comped families than for married-couple families. The composition of children's families and the time parents have for their children affect child rearing. Consequent to the increase in female-headed households, rising economic and personal need, and increased opportunities for women, the proportion of mothers who are in the workforce has climbed steadily over the past several decades. Currently, approximately two thirds of all mothers with children younger than 18 years are employed. Most families with young children depend on child care, and most child care is not of good quality. Reliance on child care involves longer days for children and families, the stress imposed by schedules and created by transitions, exposure to infections, and considerable cost. An increasing number and proportion of parents are also devoting time previously available to their children to the care of their own parents. The so-called "sandwich generation" of parents is being pulled in multiple directions. The amount and use of family time also has changed with a lengthening workday, including the amount of commuting time necessary to travel between work and home, and with the intrusion of television and computers into family life. In public opinion polls, most parents report that they believe it is more difficult to be a parent now than it used to be; people seem to feel more isolated, social and media pressures on and enticements of their children seem greater, and the world seems to be a more dangerous place. Social and public policy has not kept up with these changes, leaving families stretched for time and stressed to cope and meet their responsibilities. What can and what should pediatrics do to help families raise healthy and well-adjusted children? How can individual pediatricians better support families?

    Ni, Jie; Turaga, Pavan; Patel, Vishal M; Chellappa, Rama

    2011-11-01

    Image restoration methods that exploit prior information about images to be estimated have been extensively studied, typically using the Bayesian framework. In this paper, we consider the role of prior knowledge of the object class in the form of a patch manifold to address the deconvolution problem. Specifically, we incorporate unlabeled image data of the object class, say natural images, in the form of a patch-manifold prior for the object class. The manifold prior is implicitly estimated from the given unlabeled data. We show how the patch-manifold prior effectively exploits the available sample class data for regularizing the deblurring problem. Furthermore, we derive a generalized cross-validation (GCV) function to automatically determine the regularization parameter at each iteration without explicitly knowing the noise variance. Extensive experiments show that this method performs better than many competitive image deconvolution methods.

    O'Hora, Kendra A; Roberto, Karen A

    2017-12-14

    The purpose of this study was to explore how contextual aspects of participants' lives before and throughout relocation to assisted living (ALF) informed family experience of family life review (FLR). Fourteen families participated in a single FLR session within 6 months of the older adults' relocation. Semi-structured interviews, conducted one-month following the FLR session, were analyzed using the constant comparative method. Demographic and relational variables provided context for assessing how individual and family dynamics influenced the family relocation process. Techniques were used during the three phases of FLR (introduction, validation, consolidation) to encourage openness and mutual dialogue between family members. Health-related limitations challenged older adults' understanding and openness during the FLR. Mental health concerns linked to older adults' outlook on life, comfort in conversation during the FLR, and reflection of lifelong social ties. Family involvement and dynamics influenced how families communicated about their mutual narrative and the relocation transition. FLR is an adaptable intervention to assist older adults and their family during a transition to ALF. Although contextual challenges impacted how families experienced the FLR, they enjoyed FLR as a unifying event that promoted mutual understanding. The use of FLR facilitates enhanced understanding and communication during relocation. Older adults' health status as well as family dynamics need to be assessed prior to organizing a FLR to accommodate each families' unique needs.

    Microphthalmos is a rare, potentially devastating condition. Catsch found 30 cases of microphthalmos in a population of 26,735 (0.11%); Scouras et al. among 120,000 ophthalmic out-patients found 70 cases of microphthalmos (0.058%); among 3,557 blind adults Lindstedt found 63 cases (1.77%) and Kissel et al. among 210,000 ophthalmic out-patients found 97 cases (0.046%). Congenital microphthalmos may be: colobomatous, complicated, pure. Pure microphthalmos or nanophthalmos is a rare condition in which the eye is reduced in size with a notably high ratio of the lens volume to eye volume, but no other congenital anomalies are present. The sclera is abnormally thick. Nanophthalmos may be sporadic or hereditary: hereditary transmission may be either recessive or dominant. These eyes are anatomically predisposition to angle-closure glaucoma and occasionally associated with uveal effusion. Angle-closure glaucoma probably is the result of the natural increase in the size of the lens with age; in addition, spontaneous choroidal detachment probably may cause elevation and forward rotation of the ciliary body pushing the lens-iris diaphragm forward, with increasing of the relative pupillary block. The uveal effusion probably is the result of choroidal congestion secondary to obstruction of vortex veins by abnormally thickened sclera. Uveal effusion may also occurs spontaneously in patients with nanophthalmos between the ages of 40 to 60 years. Surgical intervention with sudden decompression of the globe, appears to aggravate the degree of uveal effusion. Three cases of familial nanophthalmos associated with angle-closure glaucoma without uveal effusion not microcornea are reported. The occurrence of nanophthalmos in the same family suggests an autosomal recessive inheritance.(ABSTRACT TRUNCATED AT 250 WORDS)

  4. Sample size re-estimation incorporating prior information on a nuisance parameter.

    Science.gov (United States)

    Mütze, Tobias; Schmidli, Heinz; Friede, Tim

    2017-11-27

    Prior information is often incorporated informally when planning a clinical trial. Here, we present an approach on how to incorporate prior information, such as data from historical clinical trials, into the nuisance parameter-based sample size re-estimation in a design with an internal pilot study. We focus on trials with continuous endpoints in which the outcome variance is the nuisance parameter. For planning and analyzing the trial, frequentist methods are considered. Moreover, the external information on the variance is summarized by the Bayesian meta-analytic-predictive approach. To incorporate external information into the sample size re-estimation, we propose to update the meta-analytic-predictive prior based on the results of the internal pilot study and to re-estimate the sample size using an estimator from the posterior. By means of a simulation study, we compare the operating characteristics such as power and sample size distribution of the proposed procedure with the traditional sample size re-estimation approach that uses the pooled variance estimator. The simulation study shows that, if no prior-data conflict is present, incorporating external information into the sample size re-estimation improves the operating characteristics compared to the traditional approach. In the case of a prior-data conflict, that is, when the variance of the ongoing clinical trial is unequal to the prior location, the performance of the traditional sample size re-estimation procedure is in general superior, even when the prior information is robustified. When considering to include prior information in sample size re-estimation, the potential gains should be balanced against the risks. Copyright © 2017 John Wiley & Sons, Ltd.

  5. Does the administration of pilocarpine prior to venom milking influence the composition of Micrurus corallinus venom?

    2018-03-01

    Considering that the scarcity of venom represents a huge challenge for biochemical and functional studies of Micrurus species (coral snakes), in this report we describe for the first time the influence of pilocarpine administration prior to venom milking on the yield and protein composition of Micrurus corallinus venom. The administration of pilocarpine resulted in an increase of about 127% in the volume of venom milked, with similar protein content. Venoms showed similar protein bands distribution and intensity by SDS-PAGE and equivalents RP-HPLC profiles. Our proteomic analysis showed that venoms milked in the presence and absence of pilocarpine presented comparable protein profiles, in terms of protein composition and relative abundance. The toxins identified were assigned to 13 protein families and represent the most complete M. corallinus venom proteome described so far, in terms of number of protein families identified. Our data indicate that the administration of pilocarpine prior to venom milking increases the venom yield and does not change significantly the venom composition of M. corallinus. The employment of pilocarpine represents a useful approach to increase the yield of venom not only for Micrurus species, but also for other genera of snakes with limitations regarding the amount of venom available. In this report, we evaluated the influence of pilocarpine administration prior to venom milking in the overall composition of M. corallinus venom. We showed that the use of pilocarpine 10min before M. corallinus venom milking increases venom yield by ~127%. Not only the volume of venom obtained is higher, but also the protein concentration of both venoms is similar, opposing the idea that a more diluted venom is obtained as a result of pilocarpine administration, observed in non-front-fanged snakes. Shotgun proteomics analysis revealed that venom milked with and without the use of this drug showed similar overall protein composition and relative abundances

    In an effort to reduce preventable injuries resulting from family fireworks displays, the Explosives Regulatory Division of Natural Resources Canada is developing a client service regulatory package - EXPLONET - which will be made available on the Internet. EXPLONET includes several components which address industry and public concerns. The initial component described here is the family educational safety module, designed to deal with the safe use of family fireworks. The objective is to reduce injuries to elementary school-age children through the delivery of an Internet-based lesson plan. The lesson plan is expected to be implemented on a pilot program basis to reach the target audience during the 1998 Halloween season when the use of fireworks is high. The lesson plan consists of four units and will be delivered over a period of four weeks prior to Hallo wen. Students will be active participants in the web-based sessions. The sessions will cover off-aspects of mathematics, history and science clustered around the central theme of fireworks safety, presented in a way to keep the children interested. The lesson will also include follow-up queries after Hallo wen, providing the children (and teachers) the opportunity to comment on what they have learned, and to identify product or safety improvements. Provision is also made for parent involvement. The module will be implemented on a pilot project basis in two schools, one in Nova Scotia and one in British Columbia. 6 refs., 1 tab., 10 figs.

    Treatment of inflammatory bowel disease (IBD) in patients with prior malignancy is challenging because therapeutic immunosuppression required for controlling IBD activity may increase the risk of cancer recurrence. Key Messages: Contrary to the observations in the post-transplant population, retrospective observational studies of IBD patients with prior malignancy have not demonstrated that immunosuppressive drugs increased significantly the risk of new or recurrent cancer. However, these studies are highly biased and do not permit the use of these drugs. Factors like the time since treatment completion, severity, and subtype of prior cancer should be weighed along with the current IBD activity before choosing the best therapeutic strategy. In practice, most cases of prior cancer require a delay of at least 2 years before starting or resuming immunosuppressants, including anti-TNF agents. This delay should be extended to 5 years in cancer with a high risk of recurrence including cancer of the urinary tract, gastrointestinal cancer, leukemias, and multiple myeloma. A special attention should be paid to cancers with a high risk of late metastasis (breast, melanoma, renal cell carcinoma). Enteral nutrition, Budesonide, mesalamine, and limited intestinal resection should be considered following the completion of cancer treatment and prior to the safe initiation of immunosuppressive treatment for IBD. Thiopurines should be avoided in case of prior Epstein-Barr virus-related lymphoma, HPV-related carcinomas, and cancer of the urinary tract. Methotrexate and anti-TNF agents seem to be safe except for the risk of recurrent melanoma for the latter. IBD patients with prior malignancy should benefit from individual decisions made on a case-by-case basis. © 2017 S. Karger AG, Basel.

    The objective for this study was to investigate the effects of prior familiarization with takeover requests (TORs) during conditional automated driving on drivers' initial takeover performance and automation trust. System-initiated TORs are one of the biggest concerns for conditional automated driving and have been studied extensively in the past. Most, but not all, of these studies have included training sessions to familiarize participants with TORs. This makes them hard to compare and might obscure first-failure-like effects on takeover performance and automation trust formation. A driving simulator study compared drivers' takeover performance in two takeover situations across four prior familiarization groups (no familiarization, description, experience, description and experience) and automation trust before and after experiencing the system. As hypothesized, prior familiarization with TORs had a more positive effect on takeover performance in the first than in a subsequent takeover situation. In all groups, automation trust increased after participants experienced the system. Participants who were given no prior familiarization with TORs reported highest automation trust both before and after experiencing the system. The current results extend earlier findings suggesting that prior familiarization with TORs during conditional automated driving will be most relevant for takeover performance in the first takeover situation and that it lowers drivers' automation trust. Potential applications of this research include different approaches to familiarize users with automated driving systems, better integration of earlier findings, and sophistication of experimental designs.

  19. Implicit Priors in Galaxy Cluster Mass and Scaling Relation Determinations

    Science.gov (United States)

    Mantz, A.; Allen, S. W.

    2011-01-01

    Deriving the total masses of galaxy clusters from observations of the intracluster medium (ICM) generally requires some prior information, in addition to the assumptions of hydrostatic equilibrium and spherical symmetry. Often, this information takes the form of particular parametrized functions used to describe the cluster gas density and temperature profiles. In this paper, we investigate the implicit priors on hydrostatic masses that result from this fully parametric approach, and the implications of such priors for scaling relations formed from those masses. We show that the application of such fully parametric models of the ICM naturally imposes a prior on the slopes of the derived scaling relations, favoring the self-similar model, and argue that this prior may be influential in practice. In contrast, this bias does not exist for techniques which adopt an explicit prior on the form of the mass profile but describe the ICM non-parametrically. Constraints on the slope of the cluster mass-temperature relation in the literature show a separation based the approach employed, with the results from fully parametric ICM modeling clustering nearer the self-similar value. Given that a primary goal of scaling relation analyses is to test the self-similar model, the application of methods subject to strong, implicit priors should be avoided. Alternative methods and best practices are discussed.

  20. Learning priors for Bayesian computations in the nervous system.

    Directory of Open Access Journals (Sweden)

    Max Berniker

    Full Text Available Our nervous system continuously combines new information from our senses with information it has acquired throughout life. Numerous studies have found that human subjects manage this by integrating their observations with their previous experience (priors in a way that is close to the statistical optimum. However, little is known about the way the nervous system acquires or learns priors. Here we present results from experiments where the underlying distribution of target locations in an estimation task was switched, manipulating the prior subjects should use. Our experimental design allowed us to measure a subject's evolving prior while they learned. We confirm that through extensive practice subjects learn the correct prior for the task. We found that subjects can rapidly learn the mean of a new prior while the variance is learned more slowly and with a variable learning rate. In addition, we found that a Bayesian inference model could predict the time course of the observed learning while offering an intuitive explanation for the findings. The evidence suggests the nervous system continuously updates its priors to enable efficient behavior.

    Tractography is the standard tool for automatic delineation of white matter tracts from diffusion weighted images. However, the output of tractography often requires post-processing to remove false positives and ensure a robust delineation of the studied tract, and this demands expert prior knowledge. Here we demonstrate how such prior knowledge, or indeed any prior spatial information, can be automatically incorporated into a shortest-path tractography approach to produce more robust results. We describe how such a prior can be automatically generated (learned) from a population, and we demonstrate that our framework also retains support for conventional interactive constraints such as waypoint regions. We apply our approach to the open access, high quality Human Connectome Project data, as well as a dataset acquired on a typical clinical scanner. Our results show that the use of a learned prior substantially increases the overlap of tractography output with a reference atlas on both populations, and this is confirmed by visual inspection. Furthermore, we demonstrate how a prior learned on the high quality dataset significantly increases the overlap with the reference for the more typical yet lower quality data acquired on a clinical scanner. We hope that such automatic incorporation of prior knowledge and the obviation of expert interactive tract delineation on every subject, will improve the feasibility of large clinical tractography studies.

    Total knee arthroplasty (TKA) is a common procedure resulting in significant post-operative pain. Percutaneous cryoneurolysis targeting the infrapatellar branch of the saphenous nerve and anterior femoral cutaneous nerve could relieve post-operative knee pain by temporarily blocking sensory nerve conduction. A retrospective chart review of 100 patients who underwent TKA was conducted to assess the value of adding perioperative cryoneurolysis to a multimodal pain management program. The treatment group consisted of the first 50 patients consecutively treated after the practice introduced perioperative (five days prior to surgery) cryoneurolysis as part of its standard pain management protocol. The control group consisted of the 50 patients treated before cryoneurolysis was introduced. Outcomes included hospital length of stay (LOS), post-operative opioid requirements, and patient-reported outcomes of pain and function. A significantly lower proportion of patients in the treatment group had a LOS of ≥2days compared with the control group (6% vs. 67%, ppain intensity and pain interference at two- and six-week follow-up, respectively. Perioperative cryoneurolysis in combination with multimodal pain management may significantly improve outcomes in patients undergoing TKA. Promising results from this preliminary retrospective study warrant further investigation of this novel treatment in prospective, randomized trials. III. Copyright © 2016 The Authors.

  3. Visibility Video Detection with Dark Channel Prior on Highway

    2016-01-01

    Full Text Available Dark channel prior (DCP has advantages in image enhancement and image haze removal and is explored to detect highway visibility according to the physical relationship between transmittance and extinction coefficient. However, there are three major error sources in calculating transmittance. The first is that sky regions do not satisfy the assumptions of DCP algorithm. So the optimization algorithms combined with region growing and coefficient correction method are proposed. When extracting atmospheric brightness, different values lead to the second error. Therefore, according to different visibility conditions, a multimode classification method is designed. Image blocky effect causes the third error. Then guided image filtering is introduced to obtain accurate transmittance of each pixel of image. Next, according to the definition meteorological optical visual range and the relationship between transmittance and extinction coefficient of Lambert-Beer’s Law, accurate visibility value can be calculated. A comparative experimental system including visibility detector and video camera was set up to verify the accuracy of these optimization algorithms. Finally, a large number of highway section videos were selected to test the validity of DCP method in different models. The results indicate that these detection visibility methods are feasible and reliable for the smooth operation of highways.

  4. Nutrient Deficiencies Are Common Prior to Bariatric Surgery.

    Obesity, defined as a body mass index >30 kg/m 2 , is a growing worldwide epidemic currently effecting 1 in 10 adults, with rates as high as 40% in the United States. The only proven long-term treatment of severe obesity on a population level is surgical modification of the gastrointestinal anatomy to induce weight loss, termed bariatric surgery. With adequate physician guidance and appropriate candidate criteria, bariatric surgery is an option for effective long-term treatment of obesity and its related comorbidities. Complications of bariatric surgery can be seen in patients who are not compliant to the recommended lifestyle and dietary changes required following bariatric surgery, including nausea, vomiting, dumping syndrome, acid reflux, and nutrition deficiencies. Despite caloric density, the diet of patients prior to bariatric surgery is often of poor nutrition quality and does not meet recommended dietary guidelines for micronutrient intake, making this an at-risk population for micronutrient malnutrition. Currently, improvements are needed in standardization of nutrition assessment as well as micronutrient cutoffs for deficiency and insufficiency. In the meantime, utilizing our current tools to conduct nutrition assessment at baseline and implement supplementation where necessary may improve the nutrition status of patients undergoing bariatric surgery, both before and after surgery, which may improve their surgical outcomes.

    Our personal preferences affect a broad array of social behaviors. This includes the way we learn the preferences of others, an ability that often relies on limited or ambiguous information. Here we report an egocentric influence on this type of social learning that is reflected in both performance and response times. Using computational models that combine inter-trial learning and intra-trial choice, we find transient effects of participants' preferences on the learning process, through the influence of priors, and persistent effects on the choice process. A second experiment shows that these effects generalize to non-social learning, though participants in the social learning experiment appeared to additionally benefit by using their knowledge about the popularity of certain preferences. We further find that the domain-general egocentric influences we identify can yield performance advantages in uncertain environments.People often assume that other people share their preferences, but how exactly this bias manifests itself in learning and decision-making is unclear. Here, authors show that a person's own preferences influence learning in both social and non-social situations, and that this bias improves performance.

  6. Regional identity and family

    Full Text Available This paper is a continuation of a study on regionalisation and family, within the project named Sociological Aspects of Multiculturality and Regionalisation and their influence on the development of AP Vojvodina and the Republic of Serbia. The author focuses her attention to operationalisation of the theoretical and methodological premises that were developed in the previous paper (Tripković, 2002: 111-127, which means that it represents the results of the second phase of the research plan. This phase includes adjusting of theoretical concepts to the fieldwork displaying the results of the research and the analysis of the findings that put a family in the context of confronting different identities, above all national and regional. As possible "identity difference" was emphasized in the research, theoretical and methodological apparatus was adjusted to this goal. That is why in this paper the replies of interviewees that can suggest or reject the assumption that their national identity can influence significantly the evaluation of identity specificities are presented and analyzed, concerning more or less visible aspects of family life, like welfare status, relations between spouses, respect to the elder, family harmony, number of children, connections with relatives, etc.

    To assess the persuasive impact of prior source exposure, two studies paired persuasive messages with a source to whom participants had previously been exposed subliminally, explicitly, or not at all. In Experiment 2, participants' attention also was drawn to information that potentially undermined the implications of any reaction to re-exposure. Compared to no exposure, prior subliminal exposure increased the source's persuasiveness, an effect not mediated by source liking. Explicit exposure increased source persuasiveness to the extent that the source was liked more and only absent a recall cue. Results favored misattributional accounts of prior exposure effects.

    In many countries, family medicine (FM) training has been conducted mainly by senior family physicians alone. However, FM training in Singapore in the last 30 years has involved specialists working in close collaboration with family physicians. The areas in which specialists are currently involved include the training of FM trainees in tertiary hospitals, the Master of Medicine in Family Medicine [MMed (FM)] and Graduate Diploma in Family Medicine (GDFM) programmes. This close relationship has been crucial in the continuing vocational and professional development of family physicians and in fostering closer collaboration between family physicians and specialists, thus ultimately benefiting patient care.

    2010-01-01

    The aim of this study is to describe the entire bentonite handling process starting from freight from harbour to storage facility and ending up to the manufacturing filling process of the bentonite block moulds. This work describes the bentonite handling prior to the process in which bentonite blocks are manufactured in great quantities. This work included a study of relevant Nordic and international well documented cases of storage, processing and techniques involving bentonite material. Information about storage and handling processes from producers or re-sellers of bentonite was collected while keeping in mind the requirements coming from the Posiva side. Also a limited experiment was made for humidification of different material types. This work includes a detailed description of methods and equipment needed for bentonite storage and processing. Posiva Oy used Jauhetekniikka Oy as a consultant to prepare handling process flow charts for bentonite. Jauhetekniikka Oy also evaluated the content of this report. The handling of bentonite was based on the assumption that bentonite process work is done in one factory for 11 months of work time while the weekly volume is around 41-45 tons. Storage space needed in this case is about 300 tons of bentonite which equals about seven weeks of raw material consumption. This work concluded several things to be carefully considered: sampling at various phases of the process, the air quality at the production/storage facilities (humidity and temperature), the level of automation/process control of the manufacturing process and the means of producing/saving data from different phases of the process.

    Objectives: Upper extremity injuries are common in youth, collegiate, and professional athletics, and may require operative management. The influence of a prior upper extremity surgery on subsequent athletic participation, injury, and surgery in college is not well understood. The purpose of this study was to investigate the impact of prior upper extremity surgery in Division I collegiate athletes on participation, injury rates, and surgery rates in college. Methods: Division I athletes who began participation in collegiate athletics from 2003 - 2009 were retrospectively identified. These athletes represented 21 sports teams at a single institution. Athletes with prior upper extremity orthopaedic surgery, including shoulder, elbow, and wrist/hand surgery, were identified through preparticipation evaluation forms. Sport, seasons played, injuries sustained during college, days missed, and college orthopaedic surgeries and diagnostic imaging were collected through sports archives, medical records, and the Sports Injury Monitoring System (SIMS) and compared to athletes with no prior history of upper extremity surgery. Subgroup analysis was performed for athletes with a history of shoulder, elbow, and wrist/hand surgeries. Results: Between 2003 and 2009, 1,145 athletes completed pre-participation evaluation forms. In total, 77 athletes (6.7%) had a history of one or more upper extremity surgeries prior to collegiate athletics. History of upper extremity surgery was most common in incoming men's water polo (15.0%), baseball (14.9%), and football (12.6%) athletes. Athletes with a prior upper extremity surgery had a higher rate of upper extremity injury in college compared to controls (Hazard Ratio = 4.127, p Athletes with a prior shoulder surgery (n=20) also had a higher rate of upper extremity injury in college compared to controls (Hazard Ratio= 15,083, p=0.02).

  3. On the prior probabilities for two-stage Bayesian estimates

    International Nuclear Information System (INIS)

    Kohut, P.

    1992-01-01

    The method of Bayesian inference is reexamined for its applicability and for the required underlying assumptions in obtaining and using prior probability estimates. Two different approaches are suggested to determine the first-stage priors in the two-stage Bayesian analysis which avoid certain assumptions required for other techniques. In the first scheme, the prior is obtained through a true frequency based distribution generated at selected intervals utilizing actual sampling of the failure rate distributions. The population variability distribution is generated as the weighed average of the frequency distributions. The second method is based on a non-parametric Bayesian approach using the Maximum Entropy Principle. Specific features such as integral properties or selected parameters of prior distributions may be obtained with minimal assumptions. It is indicated how various quantiles may also be generated with a least square technique

    In this paper, we present a fully automated generative method for brain tumor segmentation in multi-modal magnetic resonance images. The method is based on the type of generative model often used for segmenting healthy brain tissues, where tissues are modeled by Gaussian mixture models combined...... with a spatial atlas-based tissue prior. We extend this basic model with a tumor prior, which uses convolutional restricted Boltzmann machines (cRBMs) to model the shape of both tumor core and complete tumor, which includes edema and core. The cRBMs are trained on expert segmentations of training images, without...

  11. Serum Is Not Necessary for Prior Pharmacological Activation of AMPK to Increase Insulin Sensitivity of Mouse Skeletal Muscle

    2018-04-01

    Full Text Available Exercise, contraction, and pharmacological activation of AMP-activated protein kinase (AMPK by 5-aminoimidazole-4-carboxamide ribonucleotide (AICAR have all been shown to increase muscle insulin sensitivity for glucose uptake. Intriguingly, improvements in insulin sensitivity following contraction of isolated rat and mouse skeletal muscle and prior AICAR stimulation of isolated rat skeletal muscle seem to depend on an unknown factor present in serum. One study recently questioned this requirement of a serum factor by showing serum-independency with muscle from old rats. Whether a serum factor is necessary for prior AICAR stimulation to increase insulin sensitivity of mouse skeletal muscle is not known. Therefore, we investigated the necessity of serum for this effect of AICAR in mouse skeletal muscle. We found that the ability of prior AICAR stimulation to improve insulin sensitivity of mouse skeletal muscle did not depend on the presence of serum during AICAR stimulation. Although prior AICAR stimulation did not enhance proximal insulin signaling, insulin-stimulated phosphorylation of Tre-2/BUB2/CDC16- domain family member 4 (TBC1D4 Ser711 was greater in prior AICAR-stimulated muscle compared to all other groups. These results imply that the presence of a serum factor is not necessary for prior AMPK activation by AICAR to enhance insulin sensitivity of mouse skeletal muscle.

    Prior stroke within 3 months excludes patients from thrombolysis; however, patients may have computed tomography (CT) evidence of prior infarct, often of unknown time of origin. We aimed to determine if the presence of a previous infarct on pretreatment CT is a predictor of hemorrhagic complications and functional outcomes after the administration of intravenous (IV) tissue plasminogen activator (tPA). We retrospectively analyzed consecutive patients treated with IV tPA at our institution from 2009-2011. Pretreatment CTs were reviewed for evidence of any prior infarct. Further review determined if any hemorrhagic transformation (HT) or symptomatic intracerebral hemorrhage (sICH) were present on repeat CT or magnetic resonance imaging. Outcomes included sICH, any HT, poor functional outcome (modified Rankin Scale score of 4-6), and discharge disposition. Of 212 IV tPA-treated patients, 84 (40%) had evidence of prior infarct on pretreatment CT. Patients with prior infarcts on CT were older (median age, 72 versus 65 years; P=.001) and had higher pretreatment National Institutes of Health Stroke Scale scores (median, 10 versus 7; P=.023). Patients with prior infarcts on CT did not experience more sICH (4% versus 2%; P=.221) or any HT (18% versus 14%; P=.471). These patients did have a higher frequency of poor functional outcome at discharge (82% versus 50%; P<.001) and were less often discharged to home or inpatient rehabilitation center (61% versus 73%; P=.065). Visualization of prior infarcts on pretreatment CT did not predict an increased risk of sICH in our study and should not be viewed as a reason to withhold systemic tPA treatment after clinically evident strokes within 3 months were excluded.

  13. A scale-free structure prior for graphical models with applications in functional genomics.

    Directory of Open Access Journals (Sweden)

    Paul Sheridan

    Full Text Available The problem of reconstructing large-scale, gene regulatory networks from gene expression data has garnered considerable attention in bioinformatics over the past decade with the graphical modeling paradigm having emerged as a popular framework for inference. Analysis in a full Bayesian setting is contingent upon the assignment of a so-called structure prior-a probability distribution on networks, encoding a priori biological knowledge either in the form of supplemental data or high-level topological features. A key topological consideration is that a wide range of cellular networks are approximately scale-free, meaning that the fraction, , of nodes in a network with degree is roughly described by a power-law with exponent between and . The standard practice, however, is to utilize a random structure prior, which favors networks with binomially distributed degree distributions. In this paper, we introduce a scale-free structure prior for graphical models based on the formula for the probability of a network under a simple scale-free network model. Unlike the random structure prior, its scale-free counterpart requires a node labeling as a parameter. In order to use this prior for large-scale network inference, we design a novel Metropolis-Hastings sampler for graphical models that includes a node labeling as a state space variable. In a simulation study, we demonstrate that the scale-free structure prior outperforms the random structure prior at recovering scale-free networks while at the same time retains the ability to recover random networks. We then estimate a gene association network from gene expression data taken from a breast cancer tumor study, showing that scale-free structure prior recovers hubs, including the previously unknown hub SLC39A6, which is a zinc transporter that has been implicated with the spread of breast cancer to the lymph nodes. Our analysis of the breast cancer expression data underscores the value of the scale

    Full Text Available In order to conduct the prior disciplinary investigation, the employee shall be convoked in writing by the person authorized by the employer to carry out the research, specifying the subject, date, time and place of the meeting. For this purpose the employer shall appoint a committee charged with conducting the prior disciplinary investigation. Prior disciplinary research cannot be done without the possibility of the accused person to defend himself. It would be an abuse of the employer to violate these provisions. Since the employee is entitled to formulate and sustain defence in proving innocence or lesser degree of guilt than imputed, it needs between the moment were disclosed to the employee and the one of performing the prior disciplinary investigation to be a reasonable term for the employee to be able to prepare a defence in this regard. The employee's failure to present at the convocation, without an objective reason entitles the employer to dispose the sanctioning without making the prior disciplinary investigation. The objective reason which makes the employee, that is subject to prior disciplinary investigation, unable to present to the preliminary disciplinary investigation, should be at the time of the investigation in question.

  15. Fractional Gaussian noise: Prior specification and model comparison

    KAUST Repository

    Sørbye, Sigrunn Holbek

    2017-07-07

    Fractional Gaussian noise (fGn) is a stationary stochastic process used to model antipersistent or persistent dependency structures in observed time series. Properties of the autocovariance function of fGn are characterised by the Hurst exponent (H), which, in Bayesian contexts, typically has been assigned a uniform prior on the unit interval. This paper argues why a uniform prior is unreasonable and introduces the use of a penalised complexity (PC) prior for H. The PC prior is computed to penalise divergence from the special case of white noise and is invariant to reparameterisations. An immediate advantage is that the exact same prior can be used for the autocorrelation coefficient ϕ(symbol) of a first-order autoregressive process AR(1), as this model also reflects a flexible version of white noise. Within the general setting of latent Gaussian models, this allows us to compare an fGn model component with AR(1) using Bayes factors, avoiding the confounding effects of prior choices for the two hyperparameters H and ϕ(symbol). Among others, this is useful in climate regression models where inference for underlying linear or smooth trends depends heavily on the assumed noise model.

    Hypertrophy of the flight muscles is regularly observed in birds prior to long-distance migrations. We tested the hypothesis that a large migratory bird would increase flight behaviour prior to migration, in order to cause hypertrophy of the flight muscles, and upregulate key components of the aerobic metabolic pathways. Implantable data loggers were used to record year-round heart rate in six wild barnacle geese (Branta leucopsis), and the amount of time spent in flight each day was identified. Time in flight per day did not significantly increase prior to either the spring or the autumn migration, both between time periods prior to migration (5, 10 and 15 days), or when compared with a control period of low activity during winter. The lack of significant increase in flight prior to migration suggests that approximately 22 min per day is sufficient to maintain the flight muscles in condition for prolonged long-distance flight. This apparent lack of a requirement for increased flight activity prior to migration may be attributable to pre-migratory mass gains in the geese increasing workload during short flights, potentially prompting hypertrophy of the flight muscles.

    Although strong evidence indicates that the presence of a patient's family during resuscitation has a positive effect on the family, the practice is still controversial and is not consistently implemented. To explore nurses' experience with resuscitation, perceptions of the benefits and risks of having a patient's family members present, and self-confidence in having family presence at their workplace. Differences in demographic characteristics and relationships between nurses' perceptions of self-confidence and perceived risks and benefits of family presence were evaluated. The study was descriptive, with a cross-sectional survey design. A convenience sample of 154 nurses working in inpatient and outpatient units at an urban hospital were surveyed. The 63-item survey included 2 previously validated scales, demographic questions, and opinion questions. Nurses' self-confidence and perceived benefit of family presence were significantly related (r = 0.54; P resuscitation events, were specialty certified, or were members of nurses' professional organizations. Barriers to family presence included fear of interference by the patient's family, lack of space, lack of support for the family members, fear of trauma to family members, and performance anxiety. Changing the practice of family presence will require strengthening current policy, identifying a team member to attend to the patient's family during resuscitation, and requiring nurses to complete education on evidence that supports family presence and changes in clinical practice. ©2014 American Association of Critical-Care Nurses.

  19. Algorithms for biomagnetic source imaging with prior anatomical and physiological information

    This dissertation derives a new method for estimating current source amplitudes in the brain and heart from external magnetic field measurements and prior knowledge about the probable source positions and amplitudes. The minimum mean square error estimator for the linear inverse problem with statistical prior information was derived and is called the optimal constrained linear inverse method (OCLIM). OCLIM includes as special cases the Shim-Cho weighted pseudoinverse and Wiener estimators but allows more general priors and thus reduces the reconstruction error. Efficient algorithms were developed to compute the OCLIM estimate for instantaneous or time series data. The method was tested in a simulated neuromagnetic imaging problem with five simultaneously active sources on a grid of 387 possible source locations; all five sources were resolved, even though the true sources were not exactly at the modeled source positions and the true source statistics differed from the assumed statistics.

    Prior research found that 24% of graduating family medicine residents intend to provide obstetrical deliveries, but only 9% of family physicians 1 to 10 years into practice are doing so. Our study aims to describe the individual and residency program characteristics associated with intention to provide obstetrical deliveries and prenatal care. Cross-sectional data on 2014-2016 graduating residents were obtained from the American Board of Family Medicine certification examination demographic questionnaire that asked about intended provision of specific clinical activities. A hierarchical model accounting for clustering within residency programs was used to determine associations between intended provision of maternity care with individual and residency program characteristics. Of 9,541 graduating residents, 22.7% intended to provide deliveries and 51.2% intended to provide prenatal care. Individual characteristics associated with a higher likelihood of providing deliveries included female gender, graduation from an allopathic medical school, and participation in a loan repayment program. Residency characteristics included geographic location in the Midwest or West region, training at a federally qualified health center (FQHC)-based clinic, funding as a teaching health center (THC), more months of required maternity care rotations, larger residency class size, and maternity care fellowship at residency. Our findings suggest that increasing the proportion of graduating family medicine residents who intend to provide maternity care may be associated with increased exposure to maternity care training, more family medicine training programs in FQHCs and THCs, and expanded loan repayment programs.

    Full Text Available This article objective is to give an overview of the women in family enterprises on the basis of theoretical sources and approaches. In order to achieve this goal, an overview of the research findings have been provided, which have analyzed a woman's role in the family business. Family firms and family entrepreneurs have been defined differently by different authors, but what all definitions have in common is the family is involvement in business activities. A family entrepreneur can be both an individual whose entrepreneurial activities involve family members and a company, which was founded by family members. In family entrepreneurships, the members have trust towards each other and they communicate frequently, which will help them to achieve a common goal. The studies reflect predominantly men as family entrepreneurs in whose business activity the family members, including wife and children participate. The European Union has not yet provided a coherent definition of the family business, while increasing the role of women in family businesses in ensuring gender equality and giving importance to the role of the woman as the family entrepreneur

    Poverty is correlated with negative health outcomes in pediatric primary care, and is emerging as a negative prognostic indicator in pediatric oncology. However, measures of poverty amenable to targeted intervention, such as household material hardship (HMH)--including food, energy, and housing insecurity--have not been described in pediatric oncology. We describe the trajectory of family reported HMH and income poverty at a pediatric oncology referral center in New England with high psychosocial supports. Single site, prospective cohort study including 99 English-speaking families of children receiving chemotherapy for primary cancer. Families completed face-to-face surveys at two time-points: (1) Within 30 days of child's diagnosis (T1) (N = 99, response rate 88%); (2) 6-months following diagnosis (T2) (N = 93, response rate 94%). HMH was assessed in three domains: food, energy, and housing insecurity. Twenty percent of families reported low-income (≤200% Federal Poverty Level) and at least one HMH prior to their child's diagnosis. At T2, 25% of families lost >40% annual household income secondary to treatment-related work disruptions, and 29% of families reported HMH despite utilization of psychosocial supports. Low-income and HMH are prevalent in a significant proportion of newly diagnosed pediatric oncology families at a large referral center. Despite psychosocial supports, the proportion of families experiencing unmet basic needs increases during chemotherapy to nearly one in three families. HMH provides a quantifiable and remediable measure of poverty in pediatric oncology. Interventions to ameliorate this concrete component of poverty could benefit a significant proportion of pediatric oncology families. © 2015 Wiley Periodicals, Inc.

    In essentially all countries, responsibilities for child care, cooking, cleaning, and other homemaking tasks fall predominantly on the wife and mother. In addition, the childbearing years come during the period when a physicist must study hard, work long hours on research, and take temporary positions, often abroad. Thus, balancing family and career has long been one of the major barriers to women's participation in science and engineering fields, including physics. While many young women believe that they must choose between having children and having a science career, the fact is that the majority of women physicists in both developing and developed countries have successfully done both. This paper summarizes some ideas and recommendations raised in discussions, especially focused on easing the challenges of having children while in temporary jobs, returning to physics after a career break, the need for "family-friendly" working conditions, and the dual-career problem facing couples where both are scientists.

    Discussions about racial and ethnic differences may allow international, transracial adoptive families to construct multiracial and/or multiethnic family identities. However, little is known about the ways family communication influences how discussions about racial and ethnic differences occur. This study examined associations between observed family communication constructs, including engagement, warmth, and control, and how adoptive families discuss racial and ethnic differences using a sample of families with adolescent-aged children adopted internationally from South Korea ( N = 111 families, 222 adolescents). Using data collected during mid-adolescence and again during late adolescence, higher levels of maternal control and positive adolescent engagement were independently associated with a greater likelihood that family members acknowledged the importance of racial and ethnic differences and constructed a multiracial and/or multiethnic family identity. Adolescent engagement was also related to a greater likelihood that family members disagreed about the importance of racial and ethnic differences, and did not build a cohesive identity about differences.

    2015-03-01

    Prior to bariatric surgery, a preoperative weight-reducing regimen is usually adhered to in most centers. The clinical effects of such a regimen are yet to be determined. We reviewed the current literature by searching in PubMed for publications reporting clinical effects resulting from a preoperative weight loss regimen prior to bariatric surgery published from January 1, 1995 to April 30, 2014. In total, we identified 23 original publications and 2 review articles which met all inclusion criteria. These were included and fully analyzed with regard to effects of preoperative weight loss. In general, for parameters such as operating time and intraoperative complications including blood loss and recovery, inconsistent data were reported. Most studies included low number of patients and with heterogenic designs, and the results could not form the base for recommendations. However, for outcomes such as postoperative complications and weight development over time, data from large-scale studies and randomized controlled trials suggest beneficial effects following adherence to weight loss prior to bariatric surgery. Although a large amount of data in the current literature on the effects of weight loss prior to bariatric surgery are inconsistent for many outcome parameters, recently published results regarding effects on postoperative complications and weight development over time strongly suggest that such a regimen should be recommended. Whether a certain degree of weight loss should be mandatory before being accepted for bariatric surgery is, however, still controversial. © The Finnish Surgical Society 2014.

    International Nuclear Information System (INIS)

    1979-01-01

    It is shown that local gauge invariance together with dynamical (and possibly Higgs) symmetry breaking can be taken as a basis for a unified gauge theory including gravity. The criterion for the breakdown of the linear gauge symmetry of the space-time sector turns out to be the absence of a prior geometry. The usual postulates of general relativity, such as general coordinate invariance, etc., follow from the above two criteria. Gravity actions that are natural from the point of view are discussed. The extension to superspace relevant to gauge supergroups is also given, including a large number of linear and quadratic superspace invariants

    2012-01-01

    To reduce the risk of neural tube defects, the New Zealand Ministry of Health recommends women take supplemental folic acid from at least one month preconception until the end of the twelfth week of pregnancy, as well as consume folate-rich foods. A postpartum survey was conducted to describe folate knowledge and consumer behaviour among pregnant New Zealand women prior to the potential implementation of mandatory folic acid fortification of bread in May 2012. Increasing knowledge of folic acid recommendations was associated with higher supplement uptake among women who planned their pregnancies (p=0.001 for linear trend). Folic acid information failed to adequately reach some socio-demographic subgroups before conception, even when pregnancy was planned, including: indigenous Maori, Pacific and Asian women, younger women, women with large families, and women with lower educational attainment and income. Only half of all women surveyed knew some bread contained added folic acid, and among these women, less than 2% consistently chose voluntarily fortified bread during the periconceptional period by inspecting labels. Sixty-one percent of women indicated they were either in favour of mandatory fortification, or held no opinion on the matter, while 4% were opposed to the addition of folic acid to bread. Approximately one-third (35%) of women agreed with voluntary fortification. Future health promotion initiatives should be tailored toward women who are younger, less educated, with lower income, multiparous or of minority ethnicity status. Nonetheless, mandatory folic acid fortification may be required to attain the desired degree of equity.

    Purpose: Image quality in computed tomography (CT) often suffers from artifacts which may reduce the diagnostic value of the image. In many cases, these artifacts result from missing or corrupt regions in the projection data, e.g., in the case of metal, truncation, and limited angle artifacts. The authors propose a generalized correction method for different kinds of artifacts resulting from missing or corrupt data by making use of available prior knowledge to perform data completion. Methods: The proposed prior-based artifact correction (PBAC) method requires prior knowledge in form of a planning CT of the same patient or in form of a CT scan of a different patient showing the same body region. In both cases, the prior image is registered to the patient image using a deformable transformation. The registered prior is forward projected and data completion of the patient projections is performed using smooth sinogram inpainting. The obtained projection data are used to reconstruct the corrected image. Results: The authors investigate metal and truncation artifacts in patient data sets acquired with a clinical CT and limited angle artifacts in an anthropomorphic head phantom data set acquired with a gantry-based flat detector CT device. In all cases, the corrected images obtained by PBAC are nearly artifact-free. Compared to conventional correction methods, PBAC achieves better artifact suppression while preserving the patient-specific anatomy at the same time. Further, the authors show that prominent anatomical details in the prior image seem to have only minor impact on the correction result. Conclusions: The results show that PBAC has the potential to effectively correct for metal, truncation, and limited angle artifacts if adequate prior data are available. Since the proposed method makes use of a generalized algorithm, PBAC may also be applicable to other artifacts resulting from missing or corrupt data.

  15. Finding a Minimally Informative Dirichlet Prior Distribution Using Least Squares

    In a Bayesian framework, the Dirichlet distribution is the conjugate distribution to the multinomial likelihood function, and so the analyst is required to develop a Dirichlet prior that incorporates available information. However, as it is a multiparameter distribution, choosing the Dirichlet parameters is less straight-forward than choosing a prior distribution for a single parameter, such as p in the binomial distribution. In particular, one may wish to incorporate limited information into the prior, resulting in a minimally informative prior distribution that is responsive to updates with sparse data. In the case of binomial p or Poisson, the principle of maximum entropy can be employed to obtain a so-called constrained noninformative prior. However, even in the case of p, such a distribution cannot be written down in closed form, and so an approximate beta distribution is used in the case of p. In the case of the multinomial model with parametric constraints, the approach of maximum entropy does not appear tractable. This paper presents an alternative approach, based on constrained minimization of a least-squares objective function, which leads to a minimally informative Dirichlet prior distribution. The alpha-factor model for common-cause failure, which is widely used in the United States, is the motivation for this approach, and is used to illustrate the method. In this approach to modeling common-cause failure, the alpha-factors, which are the parameters in the underlying multinomial aleatory model for common-cause failure, must be estimated from data that is often quite sparse, because common-cause failures tend to be rare, especially failures of more than two or three components, and so a prior distribution that is responsive to updates with sparse data is needed.

    We present a full Bayesian analysis of the combination of current neutrino oscillation, neutrinoless double beta decay and Cosmic Microwave Background observations. Our major goal is to carefully investigate the possibility to single out one neutrino mass ordering, namely Normal Ordering or Inverted Ordering, with current data. Two possible parametrizations (three neutrino masses versus the lightest neutrino mass plus the two oscillation mass splittings) and priors (linear versus logarithmic) are exhaustively examined. We find that the preference for NO is only driven by neutrino oscillation data. Moreover, the values of the Bayes factor indicate that the evidence for NO is strong only when the scan is performed over the three neutrino masses with logarithmic priors; for every other combination of parameterization and prior, the preference for NO is only weak. As a by-product of our Bayesian analyses, we are able to (a) compare the Bayesian bounds on the neutrino mixing parameters to those obtained by means of frequentist approaches, finding a very good agreement; (b) determine that the lightest neutrino mass plus the two mass splittings parametrization, motivated by the physical observables, is strongly preferred over the three neutrino mass eigenstates scan and (c) find that logarithmic priors guarantee a weakly-to-moderately more efficient sampling of the parameter space. These results establish the optimal strategy to successfully explore the neutrino parameter space, based on the use of the oscillation mass splittings and a logarithmic prior on the lightest neutrino mass, when combining neutrino oscillation data with cosmology and neutrinoless double beta decay. We also show that the limits on the total neutrino mass ∑ mν can change dramatically when moving from one prior to the other. These results have profound implications for future studies on the neutrino mass ordering, as they crucially state the need for self-consistent analyses which explore the

    Site-specific chemical modification of proteins is important for many applications in biology and biotechnology. Recently, our laboratory and others have exploited the high specificity of the enzyme protein farnesyltransferase (PFTase) to site-specifically modify proteins through the use of alternative substrates that incorporate bioorthogonal functionality including azides and alkynes. In this study, we evaluate two aldehyde-containing molecules as substrates for PFTase and as reactants in both oxime and hydrazone formation. Using green fluorescent protein (GFP) as a model system, we demonstrate that the purified protein can be enzymatically modified with either analogue to yield aldehyde-functionalized proteins. Oxime or hydrazone formation was then employed to immobilize, fluorescently label or PEGylate the resulting aldehyde-containing proteins. Immobilization via hydrazone formation was also shown to be reversible via transoximization with a fluorescent alkoxyamine. After characterizing this labeling strategy using pure protein, the specificity of the enzymatic process was used to selectively label GFP present in crude E. coli extract followed by capture of the aldehyde-modified protein using hydrazide-agarose. Subsequent incubation of the immobilized protein using a fluorescently labeled or PEGylated alkoxyamine resulted in the release of pure GFP containing the desired site-specific covalent modifications. This procedure was also employed to produce PEGylated glucose-dependent insulinotropic polypeptide (GIP), a protein with potential therapeutic activity for diabetes. Given the specificity of the PFTase-catalyzed reaction coupled with the ability to introduce a CAAX-box recognition sequence onto almost any protein, this method shows great potential as a general approach for the selective immobilization and labeling of recombinant proteins present in crude cellular extract without prior purification.

    Full Text Available Abstract Background Overweight and obesity are associated with increased risk for pregnancy complications. Knowledge about increased risks in overweight and obese women could contribute to successful prevention strategies and the aim of this study is to assess current levels of knowledge in a pregnant population. Methods Cross sectional survey of 412 consecutive unselected women in early pregnancy in Brisbane, Australia: 255 public women attending their first antenatal clinic visit and 157 women at private maternal fetal medicine clinics undergoing a routine ultrasound evaluation prior to 20 weeks gestation. The cohort was stratified according to pre pregnancy BMI ( Results Over 75% of respondents identified that obese women have an increased risk of overall complications, including gestational diabetes and hypertensive disorders of pregnancy compared to women of normal weight. More than 60% of women asserted that obesity would increase the risk of caesarean section and less than half identified an increased risk of adverse neonatal outcomes. Women were less likely to know about neonatal complications (19.7% did not know about the effect of obesity on these than maternal complications (7.4%. Knowledge was similar amongst women recruited at the public hospital and those recruited whilst attending for an ultrasound scan at a private clinic. For most areas they were also similar between women of lower and higher BMI, but women with BMI Conclusions Many women correctly identify that overweight and obesity increases the overall risk of complications of pregnancy and childbirth. The increased risks of maternal complications associated with being obese are better known than the increased risk of neonatal complications. Maternal education status is a main determinant of the extent of knowledge and this should be considered when designing education campaigns.

    Although morbid obesity is related to excess of energy and macronutrient intake, it does not rule out the presence of micronutrient deficiencies. The aim of this study was to evaluate food intake and the prevalence of micronutrient deficiencies in a group of morbidly obese women seeking bariatric surgery. A total of 103 morbidly obese women were studied prior to bariatric surgery. Anthropometry and body composition (dual-energy X-ray absorptiometry, DEXA) were performed on all subjects. Energy and nutrient intake was determined by food frequency questionnaire. Blood tests to assess micronutrients status, including plasma iron, ferritin, transferrin, zinc, copper, calcium, phosphorus, hemoglobin, hematocrit, mean corpuscular volume (MCV), and hair zinc, were performed. Folic acid, vitamin B12, vitamin D, and parathyroid hormone (PTH) were also assessed in 66 subjects. Mean energy intake was 2801 ± 970 kcal/day. Carbohydrate, protein, and lipid intake represented 55 ± 9.1, 13.9 ± 3.3, and 32.5 ± 8.2% of total energy intake, respectively. Iron, calcium, and vitamin D intake was below the recommended dietary allowance. The prevalence of nutritional deficiencies were as follows: plasma iron 12.6%, ferritin 8.7%, transferrin 14.6%, plasma zinc 2.9%, calcium 3.3%, phosphorus 2.3%, hemoglobin 7.7%, hematocrit 13.6%, MCV 6.8%, and hair zinc 15.7%. In the subsample, 10.6% had a vitamin B12 deficiency, 71.7% showed low concentrations of vitamin D, and 66% had high PTH levels. No folic acid or copper deficiencies were detected. Despite high daily energy intake and adequate macronutrient distribution, morbidly obese Chilean women seeking bariatric surgery present with deficient intake of some micronutrients and a high prevalence of micronutrient deficiencies.

    The diagnosis of a child with autism has short- and long-term impacts on family functioning. With early diagnosis, the diagnostic process is likely to co-occur with family planning decisions, yet little is known about how parents navigate this process. This study explores family planning decision making process among mothers of young children with autism spectrum disorder in the United States, by understanding the transformation in family vision before and after the diagnosis. A total of 22 mothers of first born children, diagnosed with autism between 2 and 4 years of age, were interviewed about family vision prior to and after their child’s diagnosis. Grounded Theory method was used for data analysis. Findings indicated that coherence of early family vision, maternal cognitive flexibility, and maternal responses to diagnosis were highly influential in future family planning decisions. The decision to have additional children reflected a high level of adaptability built upon a solid internalized family model and a flexible approach to life. Decision to stop childrearing reflected a relatively less coherent family model and more rigid cognitive style followed by ongoing hardship managing life after the diagnosis. This report may be useful for health-care providers in enhancing therapeutic alliance and guiding family planning counseling. PMID:26395237

    Using the McMaster Family Assessment Device (Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's "unique perspective" or nonshared, idiosyncratic view of the family. We used a modified multitrait-multimethod confirmatory factor analysis that (a) isolated for each family member's 6 reports of family dysfunction the nonshared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by 1 or more family members and (b) extracted common variance across each family member's set of nonshared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. In addition, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these "unique perspectives" reflect about the family are discussed. PsycINFO Database Record (c) 2012 APA, all rights reserved.

    The present study aimed to examine the associations between frequency of family meals and low fruit and vegetable intake in preschool children. Promoting healthy nutrition early in life is recommended for combating childhood obesity. Frequency of family meals is associated with fruit and vegetable intake in school-age children and adolescents; the relationship in young children is less clear. We completed a secondary analysis using data from the Early Childhood Longitudinal Study-Birth Cohort. Participants included children, born in the year 2001, to mothers who were >15 years old (n = 8 950). Data were extracted from structured parent interviews during the year prior to kindergarten. We used hierarchical logistic regression to describe the relationships between frequency of family meals and low fruit and vegetable intake. Frequency of family meals was associated with low fruit and vegetable intake. The odds of low fruit and vegetable intake were greater for preschoolers who shared less than three evening family meals per week (odds ratio = 1.5, β = 0.376, P meal with family every night. Fruit and vegetable intake is related to frequency of family meals in preschool-age children. Educating parents about the potential benefits of frequent shared meals may lead to a higher fruit and vegetable consumption among preschoolers. Future studies should address other factors that likely contribute to eating patterns during the preschool years. © 2018 The British Dietetic Association Ltd.

    2010-01-01

    Bayesian anomaly detection computes posterior probabilities of anomalous events by combining prior beliefs and evidence from data. However, the specification of prior probabilities can be challenging. This paper describes a Bayesian prior in the context of disease outbreak detection. The goal is to provide a meaningful, easy-to-use prior that yields a posterior probability of an outbreak that performs at least as well as a standard frequentist approach. If this goal is achieved, the resulting posterior could be usefully incorporated into a decision analysis about how to act in light of a possible disease outbreak. This paper describes a Bayesian method for anomaly detection that combines learning from data with a semi-informative prior probability over patterns of anomalous events. A univariate version of the algorithm is presented here for ease of illustration of the essential ideas. The paper describes the algorithm in the context of disease-outbreak detection, but it is general and can be used in other anomaly detection applications. For this application, the semi-informative prior specifies that an increased count over baseline is expected for the variable being monitored, such as the number of respiratory chief complaints per day at a given emergency department. The semi-informative prior is derived based on the baseline prior, which is estimated from using historical data. The evaluation reported here used semi-synthetic data to evaluate the detection performance of the proposed Bayesian method and a control chart method, which is a standard frequentist algorithm that is closest to the Bayesian method in terms of the type of data it uses. The disease-outbreak detection performance of the Bayesian method was statistically significantly better than that of the control chart method when proper baseline periods were used to estimate the baseline behavior to avoid seasonal effects. When using longer baseline periods, the Bayesian method performed as well as the

    The Shodagor of Matlab, Bangladesh, are a seminomadic community of people who live and work on small wooden boats, within the extensive system of rivers and canals that traverse the country. This unique ecology places particular constraints on family and economic life and leads to Shodagor parents employing one of four distinct strategies to balance childcare and provisioning needs. The purpose of this paper is to understand the conditions that lead a family to choose one strategy over another by testing predictions about socioecological factors that impact the sexual division of labor, including a family's stage in the domestic cycle, aspects of the local ecology, and the availability of alloparents. Results show that although each factor has an impact on the division of labor individually, a confluence of these factors best explains within-group, between-family differences in how mothers and fathers divide subsistence and childcare labor. These factors also interact in particular ways for Shodagor families, and it appears that families choose their economic strategies based on the constellation of constraints that they face. The results of these analyses have implications for theory regarding the sexual division of labor across cultures and inform how Shodagor family economic and parenting strategies should be contextualized in future studies.

    Research has studied family functioning in families of patients suffering from eating disorders (EDs), particularly investigating the associations between mothers' and daughters' psychopathological symptoms, but limited studies have examined whether there are specific maladaptive psychological profiles characterizing the family as a whole when it includes adolescents with anorexia nervosa (AN), bulimia nervosa (BN), and binge eating disorder (BED). Through the collaboration of a network of public and private consultants, we recruited n=181 adolescents diagnosed for EDs (n=61 with AN, n=60 with BN, and n=60 with BEDs) and their parents. Mothers, fathers, and youths were assessed through a self-report measure evaluating family functioning, and adolescents completed a self-report questionnaire assessing psycho-pathological symptoms. Results showed specific family functioning and psychopathological profiles based on adolescents' diagnosis. Regression analyses also showed that family functioning characterized by rigidity predicted higher psychopathological symptoms. Our study underlines the importance of involving all members of the family in assessment and intervention programs when adolescent offspring suffer from EDs.

    Full Text Available The article deals about the results of a study of school-based Assessment of Prior Learning of adults who have enrolled as students in a VET college in order to qualify for occupations as skilled workers. Based on examples of VET teachers’ methods for assessing the students’ prior learning in the programs for gastronomes, respectively child care assistants the article discusses two issues in relation to Assessment of Prior Learing: the encounter of practical experience and school-based knowledge and the validity and reliability of the assessment procedures. Through focusing on the students’ knowing that and knowing why the assessment is based on a scholastic perception of the students’ needs for training, reflecting one of the most important challenges in Assessment of Prior Learning: how can practical experience be transformed into credits for the knowledge parts of the programs? The study shows that by combining several Assessment of Prior Learning methods and comparing the teachers’ assessments the teachers respond to the issues of validity and reliability. However, validity and reliability might be even further strengthened, if the competencies are well defined, if the education system is aware of securing a reasonable balance between knowing how, knowing that, and knowing why, and if the teachers are adequately trained for the assessment procedures.

    2017-12-01

    Conditions involving neurocognitive impairment pose enormous challenges to couples and families. However, research and practice tend to focus narrowly on immediate issues for individual caregivers and their dyadic relationship with the affected member. A broad family systems approach with attention to family processes over time is needed in training, practice, and research. In this paper, Rolland's Family Systems Illness model provides a guiding framework to consider the interaction of different psychosocial types of neurocognitive conditions and their evolution over time with individual, couple, and family life-course development. Discussion addresses key family and couple issues with mild-to-severe cognitive impairment and progressive dementias, including: communication, multigenerational legacies, threatened future neurocognitive disability, ambiguous loss, decisional capacity, reaching limits, placement decisions, issues for adult children and spousal caregivers, and the transformation of intimate bonds. Principles and guidelines are offered to help couples and families master complex challenges, deepen bonds, and forge positive pathways ahead. © 2017 Family Process Institute.

  16. Hatching time and alevin growth prior to the onset of exogenous feeding in farmed, wild and hybrid Norwegian Atlantic salmon.

    Directory of Open Access Journals (Sweden)

    Monica Favnebøe Solberg

    Full Text Available The onset of exogenous feeding, when juveniles emerge from the gravel, is a critical event for salmonids where early emergence and large size provide a competitive advantage in the wild. Studying 131 farmed, hybrid and wild Norwegian Atlantic salmon families, originating from four wild populations and two commercial strains, we investigated whether approximately 10 generations of selection for faster growth has also resulted in increased somatic growth prior to the onset of exogenous feeding. In addition, we tested whether relaxed selection in farms has allowed for alterations in hatching time between farmed and wild salmon. Across three cohorts, wild salmon families hatched earlier than farmed salmon families, while hybrid families displayed intermediate hatching times. While the observed differences were small, i.e., 1-15 degree-days (0-3 days, as water temperatures were c. 5-6°C, these data suggest additive genetic variation for hatching time. Alevin length prior to exogenous feeding was positively related to egg size. After removal of egg size effects, no systematic differences in alevin length were observed between the wild and farmed salmon families. While these results indicate additive genetic variation for egg development timing, and wild salmon families consistently hatched earlier than farmed salmon families, these differences were so small they are unlikely to significantly influence early life history competition of farmed and wild salmon in the natural environment. This is especially the case given that the timing of spawning among females can vary by several weeks in some rivers. The general lack of difference in size between farmed and wild alevins, strongly suggest that the documented differences in somatic growth rate between wild and farmed Norwegian Atlantic salmon under hatchery conditions are first detectable after the onset of exogenous feeding.

    2011-03-01

    Full Text Available Abstract Background Members of the cation diffusion facilitator (CDF family are integral membrane divalent cation transporters that transport metal ions out of the cytoplasm either into the extracellular space or into internal compartments such as the vacuole. The spectrum of cations known to be transported by proteins of the CDF family include Zn, Fe, Co, Cd, and Mn. Members of this family have been identified in prokaryotes, eukaryotes, and archaea, and in sequenced plant genomes. CDF families range in size from nine members in Selaginella moellendorffii to 19 members in Populus trichocarpa.

    Members of the cation diffusion facilitator (CDF) family are integral membrane divalent cation transporters that transport metal ions out of the cytoplasm either into the extracellular space or into internal compartments such as the vacuole. The spectrum of cations known to be transported by proteins of the CDF family include Zn, Fe, Co, Cd, and Mn. Members of this family have been identified in prokaryotes, eukaryotes, and archaea, and in sequenced plant genomes. CDF families range in size from nine members in Selaginella moellendorffii to 19 members in Populus trichocarpa. Phylogenetic analysis suggests that the CDF family has expanded within plants, but a definitive plant CDF family phylogeny has not been constructed. Representative CDF members were annotated from diverse genomes across the Viridiplantae and Rhodophyta lineages and used to identify phylogenetic relationships within the CDF family.

  20. The netrin protein family.

    The name netrin is derived from the Sanskrit Netr, meaning 'guide'. Netrins are a family of extracellular proteins that direct cell and axon migration during embryogenesis. Three secreted netrins (netrins 1, 3 and 4), and two glycosylphosphatidylinositol (GPI)-anchored membrane proteins, netrins G1 and G2, have been identified in mammals. The secreted netrins are bifunctional, acting as attractants for some cell types and repellents for others. Receptors for the secreted netrins include the Deleted in Colorectal Cancer (DCC) family, the Down's syndrome cell adhesion molecule (DSCAM), and the UNC-5 homolog family: Unc5A, B, C and D in mammals. Netrin Gs do not appear to interact with these receptors, but regulate synaptic interactions between neurons by binding to the transmembrane netrin G ligands NGL1 and 2. The chemotropic function of secreted netrins has been best characterized with regard to axon guidance during the development of the nervous system. Extending axons are tipped by a flattened, membranous structure called the growth cone. Multiple extracellular guidance cues direct axonal growth cones to their ultimate targets where synapses form. Such cues can be locally derived (short-range), or can be secreted diffusible cues that allow target cells to signal axons from a distance (long-range). The secreted netrins function as short-range and long-range guidance cues in different circumstances. In addition to directing cell migration, functional roles for netrins have been identified in the regulation of cell adhesion, the maturation of cell morphology, cell survival and tumorigenesis.

    To estimate the effect of prior successful vaginal birth after cesarean (VBAC) on the rate of uterine rupture and delivery outcome in women undergoing labor after cesarean. A retrospective cohort study of all women attempting labor after cesarean delivery in a university-affiliated tertiary-hospital (2007-2014) was conducted. Study group included women attempting vaginal delivery with a history of cesarean delivery and at least one prior VBAC. Control group included women attempting first vaginal delivery following cesarean delivery. Primary outcome was defined as the rate of uterine rupture. Secondary outcomes were delivery and maternal outcomes. Of 62,463 deliveries during the study period, 3256 met inclusion criteria. One thousand two hundred and eleven women had VBAC prior to the index labor and 2045 underwent their first labor after cesarean. Women in the study group had a significantly lower rate of uterine rupture 9 (0.7%) in respect to control 33 (1.6%), p = .036, and had a higher rate of successful vaginal birth (96 vs. 84.9%, p cesarean, prior VBAC appears to be associated with lower rate of uterine rupture and higher rate of successful vaginal birth.

    Drug repurposing (i.e., finding novel indications for established substances) has received increasing attention in industry recently. One challenge of repositioned drugs is obtaining effective patent protection, especially if the 'novel' indications have already been claimed by competitors within the same drug class. Here, I report the case of patents relating to phosphodiesterase type 5 (PDE5) inhibitors. Patentees of later-filed patents on novel indications (even when they could not observe prior patenting of their direct competitors) filed patents for which patent examiners did not see the prior-filed patents of the competitors as relevant prior art, whereas these follower patent applications often failed because of other reasons.

    Anecdotally many athletes report worse sleep in the nights prior to important competitions. Despite sleep being acknowledged as an important factor for optimal athletic performance and overall health, little is understood about athlete sleep around competition. The aims of this study were to identify sleep complaints of athletes prior to competitions and determine whether complaints were confined to competition periods. Cross-sectional study. A sample of 283 elite Australian athletes (129 male, 157 female, age 24±5 y) completed two questionnaires; Competitive Sport and Sleep questionnaire and the Pittsburgh Sleep Quality Index. 64.0% of athletes indicated worse sleep on at least one occasion in the nights prior to an important competition over the past 12 months. The main sleep problem specified by athletes was problems falling asleep (82.1%) with the main reasons responsible for poor sleep indicated as thoughts about the competition (83.5%) and nervousness (43.8%). Overall 59.1% of team sport athletes reported having no strategy to overcome poor sleep compared with individual athletes (32.7%, p=0.002) who utilised relaxation and reading as strategies. Individual sport athletes had increased likelihood of poor sleep as they aged. The poor sleep reported by athletes prior to competition was situational rather than a global sleep problem. Poor sleep is common prior to major competitions in Australian athletes, yet most athletes are unaware of strategies to overcome the poor sleep experienced. It is essential coaches and scientists monitor and educate both individual and team sport athletes to facilitate sleep prior to important competitions. Copyright © 2014 Sports Medicine Australia.

    Full Text Available Abstract Background Family doctors should care for individuals in the context of their family. Family has a powerful influence on health and illness and family interventions have been shown to improve health outcomes for a variety of health problems. The aim of the study was to investigate the Estonian family doctors' (FD attitudes to the patients' family-related issues in their work: to explore the degree of FDs involvement in family matters, their preparedness for management of family-related issues and their self-assessment of the ability to manage different family-related problems. Methods A random sample (n = 236 of all FDs in Estonia was investigated using a postal questionnaire. Altogether 151 FDs responded to the questionnaire (response rate 64%, while five of them were excluded as they did not actually work as FDs. Results Of the respondents, 90% thought that in managing the health problems of patients FDs should communicate and cooperate with family members. Although most of the family doctors agreed that modifying of the health damaging risk factors (smoking, alcohol and drug abuse of their patients and families is their task, one third of them felt that dealing with these problems is ineffective, or perceived themselves as poorly prepared or having too little time for such activities. Of the respondents, 58% (n = 83 were of the opinion that they could modify also relationship problems. Conclusions Estonian family doctors are favourably disposed to involvement in family-related problems, however, they need some additional training, especially in the field of relationship management.

    We study generalized restricted Boltzmann machines with generic priors for units and weights, interpolating between Boolean and Gaussian variables. We present a complete analysis of the replica symmetric phase diagram of these systems, which can be regarded as generalized Hopfield models. We underline the role of the retrieval phase for both inference and learning processes and we show that retrieval is robust for a large class of weight and unit priors, beyond the standard Hopfield scenario. Furthermore, we show how the paramagnetic phase boundary is directly related to the optimal size of the training set necessary for good generalization in a teacher-student scenario of unsupervised learning.

    2009-06-01

    We explore why some low income immigrant families enroll in government financed health insurance plans for their children, while others also eligible do not enroll. Our team conducted and analyzed audiotaped semi-structured interviews with families of 8 insured and 10 uninsured children focused on knowledge of and experience with seeking health insurance coverage. Common among families not enrolled in government sponsored plans were misperceptions about the insurance system, including a suspicion of the government monitoring them and/or lack of familiarity with the concept of insurance itself. Among families that did enroll, the predominant theme was the essential role of their sponsor, other kin or community in educating and assisting them with the application process. Prior research has identified external obstacles to enrollment. Our findings indicate the additional importance of facilitating social support, particularly from sponsors in mentoring new arrivals through the process of seeking insurance coverage.

    Full Text Available Abstract Background Despite the serious consequences of conflict for reproductive health, populations affected by conflict and its aftermath face tremendous barriers to accessing reproductive health services, due to insecurity, inadequate numbers of trained personnel and lack of supplies. Family planning is often particularly neglected. Methods In six conflict-affected areas in Sudan, northern Uganda and the Democratic Republic of Congo, household surveys of married or in-union women of reproductive age were conducted to determine baseline measures of family planning knowledge, attitudes and behaviors regarding contraception. Health facility assessments were carried out to assess baseline measures of family planning services availability. Data were double-entered into CSPro 3.2 and exported to SAS 9.2, which was used to calculate descriptive statistics. The studies' purposes were to guide program activities and to serve as a baseline against which program accomplishments could be measured. Results Knowledge of modern contraceptive methods was low relative to other sub-Saharan African countries, and use of modern methods was under 4% in four sites; in two sites with prior family planning services it was 12% and 16.2%. From 30% to 40% of women reported they did not want a child within two years, however, and an additional 12% to 35% wanted no additional children, suggesting a clear need for family planning services. The health facilities assessment showed that at most only one-third of the facilities mandated to provide family planning had the necessary staff, equipment and supplies to do so adequately; in some areas, none of the facilities were prepared to offer such services. Conclusions Family planning services are desired by women living in crisis situations when offered in a manner appropriate to their needs, yet services are rarely adequate to meet these needs.

    The tobacco paradox is a phenomenon insufficiently explained by previous studies. This study analyses the prognostic role of prior or active smoking in patients with acute coronary syndrome. We obtained data from the ARIAM registry, between 2001 and 2012. The study included 42,827 patients with acute coronary syndrome (mean age, 65±13 years; 26.4% women). The influence of smoking and that of being an ex-smoker on mortality was analysed using a multivariate analysis. The smokers were younger, were more often men, had less diabetes, hypertension and prior history of heart failure, stroke, arrhythmia and renal failure and more frequently had ST-elevation and a family history of smoking. The ex-smokers had more dyslipidaemia and history of angina, myocardial infarction, ischemic heart disease, peripheral vasculopathy and chronic bronchial disease. Smokers and ex-smokers less frequently developed cardiogenic shock (smokers 4.2%, ex-smokers 4.7% and nonsmokers 6.9%, P<.001). Hospital mortality was 7.8% for the nonsmokers, 4.9% for the ex-smokers and 3.1% for the smokers (P<.001). In the multivariate analysis, the smoker factor lost its influence in the prognosis (-0.26%, p=.52 using an inverse probability calculation; and+0.26%, P=.691 using a propensity analysis). However, the exsmoker factor showed a significant reduction in mortality in both tests (-2.4% in the inverse probability analysis, P<.001; and -1.5% in the propensity analysis, P=.005). The tobacco paradox is a finding that could be explained by other prognostic factors. Smoking cessation prior to hospitalization for acute coronary syndrome is associated with a better prognosis.

    As rates for cesarean births continue to rise, more women are faced with the choice to plan a vaginal or a repeat cesarean birth after a previous cesarean. The objective of this population-based retrospective cohort study was to compare the safety of planned vaginal birth with cesarean birth after 1-2 previous cesarean sections. We identified singleton term births in British Columbia from 2000 to 2008 using data from the British Columbia Perinatal Data Registry. Women carrying a singleton fetus in cephalic presentation at term (37-41 weeks of gestation completed) with 1-2 prior cesarean births were included. Those with gestational hypertension, pre-existing diabetes and cardiac disease were excluded. Maternal and neonatal outcomes were classified as either life-threatening or non-life threatening. We compared outcomes among women with none versus at least 1 previous vaginal birth, by planned method of delivery. We estimated relative risks (RR) and 95% confidence intervals (CI) for composite outcomes using Poisson regression. Of the 33 812 women in the sample, 5406 had a history of vaginal delivery and 28 406 did not. The composite risk for life-threatening maternal outcomes was elevated among women planning vaginal compared with cesarean birth both with and without a prior vaginal birth (RR 2.06, 95% CI 1.20-3.52) and (2.52, 95% CI 2.04-3.11). Absolute differences (attributable risk [AR]) were 1.01% and 1.31% respectively. Non-life threatening maternal outcomes were decreased among women planning a vaginal birth if they had had at least 1 prior vaginal delivery (RR 0.51, 95% CI 0.33-0.77; AR 1.17%). The composite risk of intrapartum stillbirth, neonatal death or life-threatening neonatal outcomes did not differ among women planning vaginal or cesarean birth with a prior vaginal delivery and non-life threatening neonatal outcomes were decreased, (RR 0.67, 95% CI 0.52-0.86); AR 1.92%). After 1 or 2 previous cesarean births, risks for adverse outcomes between planned

    To describe the family health, functioning, social support and child maltreatment risk and associations between them in families expecting a baby. Finland was one of the first countries in banning corporal punishment against children over 30 years ago. Despite of this, studies have shown that parents physically abuse their children. In addition, professionals struggle in intervention of this phenomenon. Abusive parents should be recognised and helped before actual violent behaviour. A follow-up case-control study, with a supportive intervention in the case group (families with a heightened risk) in maternity and child welfare clinics. The baseline results of families are described here. Child maltreatment risk in families expecting a baby was measured by Child Abuse Potential Inventory. The health and functioning was measured by Family Health, Functioning and Social Support Scale. Data included 380 families. A total of 78 families had increased risk for child maltreatment. Heightened risk was associated with partners' age, mothers' education, partners' father's mental health problems, mothers' worry about partners' drinking and mothers' difficulties in talking about the family's problems. Risk was associated with family functioning and health. Families with risk received a less support from maternity clinics. Families with child maltreatment risk and related factors were found. This knowledge can be applied for supporting families both during pregnancy and after the baby is born. Professionals working with families in maternity clinics need tools to recognise families with risk and aid a discussion with them about the family life situation. The Child Abuse Potential, as a part of evaluating the family life situation, seems to prove a useful tool in identifying families at risk. The results offer a valid and useful tool for recognising families with risk and provide knowledge about high-risk family situations. © 2016 John Wiley & Sons Ltd.

  17. Family environment and child development

    Tina Kavčič

    2005-04-01

    Full Text Available The paper presents an overview of research findings on influence of family environment, especially parental behaviour, on child's development. Contemporary authors question early socialization researchers' claims that family characteristics and parental behaviour have important influence on behaviour of their children. Later researchers examined the size and durability of possible effects of family environment on child development. In addition, they focused on establishing whether it is actually the parental behaviour that influences child's development or, on the contrary, parental behaviour represents mainly a reaction to child's characteristics. Behaviour genetic studies have provided evidence that many traditional measures of family environment, including measures of parental behaviour, show genetic influence, thus reflecting genetically influenced child characteristics. Behaviour geneticists also suggest that environmental influences on child (personality development include predominantly non-shared environment, i.e. individual child's specific experiences, his/her own perceptions and interpretations of objectively same events. Based on empirically determined significant genetic effects on most behavioural traits and inconclusive results of studies on effects of family environment on child development some authors believe that it is not the parents, but rather genetic factor and/or peers who have the key role in child development. With respect to findings of behaviour genetics numerous recent studies of relations between family environment and child development involve child specific measures of (extrafamilial environment and examine the interactions between characteristics of an individual and those of his/her environment.

    Development of sensitive sequence search procedures for the detection of distant relationships between proteins at superfamily/fold level is still a big challenge. The intermediate sequence search approach is the most frequently employed manner of identifying remote homologues effectively. In this study, examination of serine proteases of prolyl oligopeptidase, rhomboid and subtilisin protein families were carried out using plant serine proteases as queries from two genomes including A. thaliana and O. sativa and 13 other families of unrelated folds to identify the distant homologues which could not be obtained using PSI-BLAST. We have proposed to start with multiple queries of classical serine protease members to identify remote homologues in families, using a rigorous approach like Cascade PSI-BLAST. We found that classical sequence based approaches, like PSI-BLAST, showed very low sequence coverage in identifying plant serine proteases. The algorithm was applied on enriched sequence database of homologous domains and we obtained overall average coverage of 88% at family, 77% at superfamily or fold level along with specificity of ~100% and Mathew's correlation coefficient of 0.91. Similar approach was also implemented on 13 other protein families representing every structural class in SCOP database. Further investigation with statistical tests, like jackknifing, helped us to better understand the influence of neighbouring protein families. Our study suggests that employment of multiple queries of a family for the Cascade PSI-BLAST searches is useful for predicting distant relationships effectively even at superfamily level. We have proposed a generalized strategy to cover all the distant members of a particular family using multiple query sequences. Our findings reveal that prior selection of sequences as query and the presence of neighbouring families can be important for covering the search space effectively in minimal computational time.

    In childhood chronic illness, family communication can impact the child's and parents' psychosocial well-being. However, little is known about family communication in the context of epilepsy in childhood. The aim of this systematic review was to identify the existing evidence available on communication strategies adopted by families living with childhood epilepsy, including; the facilitators, barriers and challenges experienced by families when choosing to communicate, or not, about epilepsy; and the consequences of this communication. Papers published in the English language prior to March 2015 were identified following a search of six electronic databases: PubMed, MEDLINE, Web of Science, PsycINFO, CINAHL, and Scopus. Studies were included if they involved a sample of parents of children with epilepsy or children/young people with epilepsy (0-18years of age) and used qualitative, quantitative, or mixed methods. Following a comprehensive search and screening process, 26 studies were identified as eligible for inclusion in the review. No studies identified specific communication strategies adopted by families living with childhood epilepsy. Some studies found that talking about epilepsy with family members had positive consequences (e.g., communication as an effective coping strategy), with no negative consequences reported in any of the studies. The main barrier to communication for parents was an unwillingness to use the word "epilepsy" because of the perceived negative social connotations associated with the health condition. For children with epilepsy, barriers were as follows: parental desire to keep epilepsy a secret, parents' tendency to deny that the child had epilepsy, parental overprotection, and parents' tendency to impose greater restrictions on the child with epilepsy than on siblings without epilepsy. Future research investigating the communication strategies of families living with epilepsy is needed in order to create effective communication

    Family management is an important concept in caring for chronically ill children. The purpose of this study is to determine the applicability of the Family Management Style Framework for Chinese families with a child who has a chronic condition. The children ranged in age from 6 to 16 years. The structural equation modeling approach was utilized to examine the relationships among the contextual variables, the family management, the child, and the family functioning. A total of 538 caregivers from seven hospitals in China were included in this study. The final model adequately fitted the data. The predictor variables accounted for 23%, 26%, 7.8%, and 12% of the variance in the easy and the challenging parts of family management and the child and family unit, respectively. These findings indicated that the framework is applicable to Chinese families. This result reinforces the importance of interventions designed to enable caregivers to improve family management.

    Jonkman, Jeffrey; Blinn-Pike, Lynn; Worthy, Sheri Lokken

    2013-03-01

    Background and aims The relationship between college student gambling, parenting styles, and family environments is a neglected area of gambling research. Do parenting styles indirectly influence problem gambling behaviors via family environments? Do poor family environments, characterized by high levels of conflict and low levels of cohesion, increase the likelihood of problem gambling among youth? This study explored the interrelationships among college students' current gambling behaviors and a) having an emotionally close and supportive family environment, b) having nagging and critical parents, c) having an authoritative mother, and d) frequency of alcohol consumption. Methods and results Survey data were collected from 450 undergraduate students enrolled in introductory psychology classes at two state universities in a southern state. Feeling that one has nagging and critical parents was associated with gambling in more venues, while the opposite was true for having emotionally close and supportive families. However, perceptions of having authoritative mothers were not related to gambling. The results also showed that more frequent alcohol consumption was associated with higher odds of gambling in casinos, playing cards for money, betting on sports, gambling on the Internet, higher gambling losses, and a larger number of gambling venues. Conclusions As with any exploratory research, there are several unique lines of inquiry that can, and should, follow from these findings, including more research on how college students' attitudes toward gambling activities may have begun prior to college and been influenced by their feelings about their homes and parents.

    Full Text Available Abstract Background Prior studies on the impact of problem gambling in the family mainly include help-seeking populations with small numbers of participants. The objective of the present stratified probability sample study was to explore the epidemiology of problem gambling in the family in the general population. Methods Men and women 16–74 years-old randomly selected from the Norwegian national population database received an invitation to participate in this postal questionnaire study. The response rate was 36.1% (3,483/9,638. Given the lack of validated criteria, two survey questions ("Have you ever noticed that a close relative spent more and more money on gambling?" and "Have you ever experienced that a close relative lied to you about how much he/she gambles?" were extrapolated from the Lie/Bet Screen for pathological gambling. Respondents answering "yes" to both questions were defined as Concerned Significant Others (CSOs. Results Overall, 2.0% of the study population was defined as CSOs. Young age, female gender, and divorced marital status were factors positively associated with being a CSO. CSOs often reported to have experienced conflicts in the family related to gambling, worsening of the family's financial situation, and impaired mental and physical health. Conclusion Problematic gambling behaviour not only affects the gambling individual but also has a strong impact on the quality of life of family members.

  5. Preparing learners with partly incorrect intuitive prior knowledge for learning

    2014-07-01

    Full Text Available Learners sometimes have incoherent and fragmented intuitive prior knowledge that is (partly ‘incompatible’ with the to-be-learned contents. Such knowledge in pieces can cause conceptual disorientation and cognitive overload while learning. We hypothesized that a pre-training intervention providing a generalized schema as a structuring framework for such knowledge in pieces would support (reorganizing-processes of prior knowledge and thus reduce unnecessary cognitive load during subsequent learning. Fifty-six student teachers participated in the experiment. A framework group underwent a pre-training intervention providing a generalized, categorical schema for categorizing primary learning strategies and related but different strategies as a cognitive framework for (re-organizing their prior knowledge. Our control group received comparable factual information but no framework. Afterwards, all participants learned about primary learning strategies. The framework group claimed to possess higher levels of interest and self-efficacy, achieved higher learning outcomes, and learned more efficiently. Hence, providing a categorical framework can help overcome the barrier of incorrect prior knowledge in pieces.

  6. Weight Smoothing for Generalized Linear Models Using a Laplace Prior

    Science.gov (United States)

    Xia, Xi; Elliott, Michael R.

    2017-01-01

    When analyzing data sampled with unequal inclusion probabilities, correlations between the probability of selection and the sampled data can induce bias if the inclusion probabilities are ignored in the analysis. Weights equal to the inverse of the probability of inclusion are commonly used to correct possible bias. When weights are uncorrelated with the descriptive or model estimators of interest, highly disproportional sample designs resulting in large weights can introduce unnecessary variability, leading to an overall larger mean square error compared to unweighted methods. We describe an approach we term ‘weight smoothing’ that models the interactions between the weights and the estimators as random effects, reducing the root mean square error (RMSE) by shrinking interactions toward zero when such shrinkage is allowed by the data. This article adapts a flexible Laplace prior distribution for the hierarchical Bayesian model to gain a more robust bias-variance tradeoff than previous approaches using normal priors. Simulation and application suggest that under a linear model setting, weight-smoothing models with Laplace priors yield robust results when weighting is necessary, and provide considerable reduction in RMSE otherwise. In logistic regression models, estimates using weight-smoothing models with Laplace priors are robust, but with less gain in efficiency than in linear regression settings. PMID:29225401
