Levonorgestrel (LNG), a dedicated emergency contraception (EC) product, has been available over-the-counter in China for more than 14 yr. Although LNG-EC is considered to have no effects on the developing fetus if the contraceptive fails and pregnancy occurs, there have been a few studies specifically examining this issue. The purpose of this study was to compare the physical and mental development of children born after LNG-EC failure with that of a cohort of children born to mothers with no history of exposure to LNG or any teratogenic substances. A group of 195 children who were exposed to LNG-EC during their mothers' conception cycle (study group) were matched to a group of 214 children without exposure to LNG (control group). The physical and mental development of the children were evaluated and compared over a 2-yr period. There were four congenital malformations in the study group and three in the control group (2.1% vs. 1.4%, respectively, P > 0.05). Over the 2-yr follow-up period, there were no statistically significant differences between the two groups with respect to children's weight, height, head circumference, and intelligence scores, and the values of all parameters of both groups were similar to those of the national standards. In summary, LNG-EC has no effect on the physical growth, mental development, or occurrence of birth defects in children born from pregnancies in which EC failed. © 2014 by the Society for the Study of Reproduction, Inc.

The author undertook a project to support nurses participating in study groups as part of their strategy to prepare for the Canadian Nurses Association certification exams. Feedback was obtained from CNA certified nurses, study group participants and facilitators and other key stakeholders to develop a study group resource manual. CNA certification is a voluntary national nursing specialty credential that offers Canadian nurses the opportunity to demonstrate their knowledge and skills by meeting eligibility criteria and successfully writing an examination. Initially, development of a study group manual was the principal aim of the project; however, nurses' insights into their study group experiences became the focal point. Nurses recognized that being part of a study group was an effective learning strategy and a valuable networking experience. The author highlights nurses' study group experiences, describes the use of a nursing leadership conceptual model to frame the project and discusses the concept of continuing competence.

This study aims to examine the pattern of group formation, related to the stimulation of change through the empowerment of farmers and poor fishermen The pattern of group formation is the basis for sustainable development. The research method used is qualitative descriptive method and relevant research type such as case study and triangulasi. The results of the study showed that (1) stimulation of changes made through development programs or community empowerment in the areas studied both among farm households and poor fishermen households for some programs received positive response from farmers and fishermen. However, the collective commitment to the breeding is relatively weak, since the group formed in each program is not done through good planning and concepts. (2) there are two patterns of group formation that are natural and formed formations initiated by outsiders. Groups that are naturally formed are more institutionalized and have characteristics such as intense and relatively routine interaction, strong mutual trust, and have a common form or mechanism shared for common purposes. The group can form the basis for sustainable development in improving the welfare of the poor.

The paradigm of etiology of early childhood caries (ECC) is shifting toward genetics. Of various inherited factors, blood group of an individual is genetically determined. The aim of the study is to determine if blood group of an individual will serve as a potential risk factor in the development of ECC. A cross-sectional study was conducted in Chennai. Blood samples were collected from a total of 500 children <71 months of age for determination of the blood group. Of which 96 children (24 per blood group) were randomly selected and were included in the study. Oral screening of the selected children was done by a pediatric dentist who was blinded to the blood group of the children. Decayed, extracted, and filling index was noted. Details on other associated factors for the development of ECC such as the socioeconomic status, oral hygiene measures, diet, and feeding practices were collected by directly interviewing the parents through a questionnaire. Statistical analysis was done using Chi-square and Kruskal-Wallis test and post hoc Tukey test with significance level set at 0.05. Intergroup analysis of the associated factors showed no significant differences between the children of different blood groups. A statistically significant relation was noted between the blood groups and development of ECC (P = 0.025). Blood group is a potential risk indicator for the development of ECC.

The aim of this study was to investigate the effects of exposure to a 900-MHz electromagnetic field (EMF) produced by mobile phones on the renal development of prenatal rats. Histopathological changes and apoptosis in the kidneys, together with levels of urea, creatinine and electrolyte in serum were determined. A total of 14 Sprague-Dawley rats were studied. Pregnant rats were divided into two equal groups: a control group and an EMF-exposed group. The study group was exposed to 900-MHz of EMF during the first 20 days of pregnancy, while the control group was unexposed to EMF. Sections obtained from paraffin blocks were stained for caspase-3 by immunohistochemistry, hematoxylin-eosin and Masson's trichrome. Mild congestion and tubular defects, and dilatation of Bowman's capsule were observed in the kidney tissues of rats in the exposed group. Apoptosis was evaluated using anti-caspase-3; stronger positive staining was observed in the renal tubular cells in the study group than those of the control group. Although there was a significant difference between the study and control groups in terms of K+ level (p<0.05), no significant difference was observed in the other parameters studied (p>0.05). Our study shows that the electromagnetic waves propagated from mobile phones have harmful effects on the renal development of prenatal rats.

The study investigated the effect of flurbiprofen on the development of anencephaly in early stage chicken embryos. We looked at four groups with a total of 36 embryos. There was a control group, a normal saline group, a normal-dose group and a high-dose group with ten, ten, eight and eight eggs with embryo respectively. Two embryos in the control group, studied with light microscopy at 48 h, were consistent with 28-29 hours' incubation in the Hamburger-Hamilton System. They had open neural tubes. The other embryos in this group were considered normal. One embryo in the normal saline group was on the occlusion stage at 48 h. One embryo showed an open neural tube. They were compatible with 28-29 hours' incubation in the Hamburger-Hamilton system. The remaining eight embryos showed normal development. In the normal dose group, one embryo showed underdevelopment of the embryonic disc and the embryo was dead. In four embryos, the neural tubes were open. One cranial malformation was found that was complicated with anencephaly in one embryo. In two embryos the neural tubes were closed, as they showed normal development, and they reached their expected stages according to the Hamburger-Hamilton classification. There was no malformation or growth retardation. Four experimental embryos were anencephalic in the high dose group, and three embryos had open neural tubes. One embryo exhibited both anencephaly and a neural tube closure defect. None of the embryos in this group showed normal development. Even the usual therapeutic doses of flurbiprofen increased the risk of neural tube defect. Flurbiprofen was found to significantly increase the risk of anencephaly. The provision of improved technical materials and studies with larger sample sizes will reveal the stage of morphological disruption during the development of embryos.

Clinical commissioning groups (CCGs) are required to demonstrate meaningful patient and public engagement and involvement (PPEI). Recent health service reforms have included financial incentives for general practices to develop patient reference groups (PRGs). To explore the impact of the patient participation direct enhanced service (DES) on development of PRGs, the influence of PRGs on decision making within general practice, and their interface with CCGs. A mixed-methods approach within three case study sites in England. Three case study sites were tracked for 18 months as part of an evaluation of PPEI in commissioning. A sub-study focused on PRGs utilising documentary and web-based analysis; results were mapped against findings of the main study. Evidence highlighted variations in the establishment of PRGs, with the number of active PRGs via practice websites ranging from 27% to 93%. Such groups were given a number of descriptions such as patient reference groups, patient participation groups, and patient forums. Data analysis highlighted that the mode of operation varied between virtual and tangible groups and whether they were GP- or patient-led, such analysis enabled the construction of a typology of PRGs. Evidence reviewed suggested that groups functioned within parameters of the DES with activities limited to practice level. Data analysis highlighted a lack of strategic vision in relation to such groups, particularly their role within an overall patient and PPEI framework). Findings identified diversity in the operationalisation of PRGs. Their development does not appear linked to a strategic vision or overall PPEI framework. Although local pragmatic issues are important to patients, GPs must ensure that PRGs develop strategic direction if health reforms are to be addressed. © British Journal of General Practice 2015.

The study assessed the neurodevelopment of children with isolated Robin sequence (IRS) and evaluated if children treated exclusively with nasopharyngeal intubation (NPI) present delay in neurological development. The prospective and cross-sectional study was conducted at the Hospital for Rehabilitation of Craniofacial Anomalies, Brazil. Children with IRS were divided into two groups according to the type of treatment in early infancy: 38 were treated with NPI (more severe cases) and 24 with postural treatment (less severe cases). Regarding interventions, children were assessed at 2 to 6 years of age using the Denver II Developmental Screening Test (Denver II) and Neurological Evolutionary Examination (NEE). According to Denver II, 73.7% in the NPI group and 79.2% in the postural group presented normal development. This result was similar to the results of different studies in the literature with typical population. Considering all areas of development, there were no significant differences in Denver II between the NPI and postural groups (P = .854). In the NPI group, 89.5% of children and 87.5% in the postural group presented normal development in NEE. Language was the most affected area, as 18.4% and 20.8% of children in NPI and postural group, respectively, presented risk for delay in the Denver II. The increased risk for delay in language area was probably due to anatomical conditions of the muscles involved in speech, and to hearing oscillations, as 47.4% in NPI group and 58.3% in postural group underwent myringotomy. IRS treated with NPI had neurological development similar to those in less severe cases. Children treated exclusively with NPI did not present delay in neurological development.

The anthropometric data were studied in early school aged (6-7 years old) children and the degree of harmonization during physical development was evaluated. Representative population of 400 otherwise healthy early school aged children was included in study group. Study period covered the end of school year. In the selected under observation focused population the level of individual anthropometric data was determined in percentile intervals according its position. Anthropometric data assessments by using percentile method it was revealed in early school aged (6-7 years of old children) excess in body height and weight in comparison with normal values. This phenomenon indicates the prevalence of acceleration and weight gain. Anthropometric data in boys were increased while comparing with physical development data in girls. This result difference has the tendency to statistically insignificant. Physical development harmonization values were studied in 200 children. Harmonized physical development revealed in 50 children (25%); disharmonized physical development I 50 children (15%), among them with I degree weight gain were 48 (24%), and with I degree weight deficit were 2 (1%). Markedly disharmonized development had 100 children (50%), among them with II degree weight gain were 98 (49%), and with II degree weight deficit were 2 (1%). According to the children's anthropometric data and assessment by physical development harmonization percentiles tables three groups of children were organized: main, risk group and the group with deviation in physical development. On the basis of resulted data the study of early school age children's physical development gives possibility for risk groups stratification, which in turn itself makes a strong basis for reasonable preventive measurements and stepwise monitoring implementation.

2014-03-01

This study investigated whether neurophysiologic responses (auditory evoked potentials) differ between typically developed children and children with phonological disorders and whether these responses are modified in children with phonological disorders after speech therapy. The participants included 24 typically developing children (Control Group, mean age: eight years and ten months) and 23 children clinically diagnosed with phonological disorders (Study Group, mean age: eight years and eleven months). Additionally, 12 study group children were enrolled in speech therapy (Study Group 1), and 11 were not enrolled in speech therapy (Study Group 2). The subjects were submitted to the following procedures: conventional audiological, auditory brainstem response, auditory middle-latency response, and P300 assessments. All participants presented with normal hearing thresholds. The study group 1 subjects were reassessed after 12 speech therapy sessions, and the study group 2 subjects were reassessed 3 months after the initial assessment. Electrophysiological results were compared between the groups. Latency differences were observed between the groups (the control and study groups) regarding the auditory brainstem response and the P300 tests. Additionally, the P300 responses improved in the study group 1 children after speech therapy. The findings suggest that children with phonological disorders have impaired auditory brainstem and cortical region pathways that may benefit from speech therapy.

In the present study, various freezing containers were tested for mouse embryos of respective developmental stages; embryos were vitrified and then their survival rate and developmental rate were monitored. Mouse two cell, 8 cell, and blastula stage embryos underwent vitrification freezing-thawing and then their recovery rate, survival rate, development rate, and hatching rate were investigated. EM-grid, OPS, and cryo-loop were utilized for vitrification freezing-thawing of mouse embryos. It was found that recovery rate and survival rate were higher in the group of cryo-loop compared to those of EM-grid (p < 0.05). Embryonic development rate, two cell embryos to blastocyst, as well as hatching rate were higher in the control group compared to the EM-grid group and OPS group (p < 0.05), yet no difference was noted between the control group and cryo-loop group. Development rate and hatching rate of eight cell morulae and blastocysts were all lower in the treatment groups than the control group whilst hatching rate of blastocysts was higher in the control group compared to the groups of EM-grid and OPS (p < 0.05); although the cryo-loop group was shown to be slightly higher than other groups, it was not statistically significant. In the study, we investigate effects of freezing containers on vitrified embryos of respective developmental stages; it was demonstrated that higher developmental rate was shown in more progressed (or developed) embryos with more blastomeres. There was however, no difference in embryonic development rate was shown amongst containers. Taken together, further additional studies are warranted with regards to 1) manipulation techniques of embryos for various vitrification freezing containers and 2) preventive measures against contamination via liquid nitrogen.

Since recent years Dutch diabetes care has increasingly focused on improving the quality of care by introducing the concept of care groups (in Dutch: 'zorggroepen'), care pathways and improving cooperation with involved care professionals and patients. This study examined how participating actors in care groups assess the development of their diabetes services and the differences and similarities between different stakeholder groups. A self-evaluation study was performed within 36 diabetes care groups in the Netherlands. A web-based self-assessment instrument, based on the Development Model for Integrated Care (DMIC), was used to collect data among stakeholders of each care group. The DMIC defines nine clusters of integrated care and four phases of development. Statistical analysis was used to analyze the data. Respondents indicated that the diabetes care groups work together in well-organized multidisciplinary teams and there is clarity about one another's expertise, roles and tasks. The care groups can still develop on elements related to the management and monitoring of performance, quality of care and patient-centeredness. The results show differences (p < 0.01) between three stakeholders groups in how they assess their integrated care services; (1) core players, (2) managers/directors/coordinators and (3) players at a distance. Managers, directors and coordinators assessed more implemented integrated care activities than the other two stakeholder groups. This stakeholder group also placed their care groups in a further phase of development. Players at a distance assessed significantly less present elements and assessed their care group as less developed. The results show a significant difference between stakeholder groups in the assessment of diabetes care practices. This reflects that the professional disciplines and the roles of stakeholders influence the way they asses the development of their integrated care setting, or that certain stakeholder groups could be less involved or informed.

There are few studies examining development of acute kidney injury (AKI) in the various types of patients in intensive care units (ICUs). Presently described is evaluation of risk factors and development of AKI in different groups of ICU patients. Present study was performed in 3 different ICUs. Development of AKI was measured using Acute Kidney Injury Network (AKIN) classification system. Total of 300 patients who were treated in trauma, neurosurgery, or general ICU departments (due to head injury, aneurysmal subarachnoid hemorrhage [aSAH], or severe sepsis/septic shock, respectively) were assessed for incidence, risk factors, and development of AKI. AKI did not develop in aSAH patients when evaluated based on serum creatinine level; however, it was observed in 5% of aSAH patients according to volume adjusted creatinine (VACr) level. AKI developed in 76% of sepsis group, and in 20% of head injury group, based on AKIN classification, according to both serum and VACr levels. Incidence of AKI was significantly higher in sepsis group (p<0.001). Only use of vasopressor was significantly related to AKI development in sepsis and head injury groups. Mortality rate was 8%, 22%, and 42% in aSAH, head injury, and sepsis groups, respectively. AKI development and vasopressor use were significantly related to mortality in sepsis group. Despite similar characteristics and risk factors, there were fewer instances of AKI in aSAH group. Hypertension or hydration therapy used to treat vasospasm and polyuria due to cerebral salt-wasting syndrome may prevent aSAH patients from developing AKI.

2001-01-01

Body height and weight are important indicators of children's health status. There are many evidences that children from disadvantaged families have lower height and weight than children of the same age from families without social risk. The aim of this study was to investigate characteristics of growth and development of children from economically disadvantaged families. The study was partly retrospective and partly prospective. The retrospective study included 509 children from disadvantaged families hospitalized at the Institute of Child and Adolescent Health Care in Novi Sad, during a five-year period. The prospective study included 90 children from disadvantaged families (experimental group) and 132 children from families without social risk (control group) hospitalized at the Institute during a six month period. Height/length, weight, head circumference, and psychomotor/intellectual development have been examined. In the retrospective study results were compared with theoretically expected values, whereas the prospective study results of experimental and control group were compared. In the retrospective study that included only children from disadvantaged families, 136 (26.7%) children had height/length, 173 (34%) had weight, and 86 (16.9%) children had head circumference below 10th percentile. Delay in psychomotor/intellectual development was established in 177 (34.8%) children. Children from families with social risk have significantly more often height/length, weight, head circumference and developmental delay than theoretically expected. In the prospective study 40 (44.4%) children from experimental group had height/length, 29 (32.2%) had weight, 20 (22.2%) children had head circumference below 10th percentile, and 17 (26.2%) had delay in psychomotor/intellectual development. Children from disadvantaged families (experimental group) significantly more often had delay in growth and development comparing with children from families without social risk (control group). Children from disadvantaged families significantly more often exhibit delay in growth and development, comparing with children of the same age from families without social risk. Therefore, pediatricians should consider social risk factors whenever treating children with growth or developmental delay.

Neuropsychological studies in children who are exposed to lead during their early brain development have shown to develop behavioural and cognitive deficit. The aim of the present study was to assess the cellular damage in hippocampus, amygdala and cerebellum of rat pups exposed to lead during different periods of early brain development. Five groups of rat pups were investigated. (a) Control group (n = 8) (mothers of these rats were given normal drinking water throughout gestation and lactation), (b) pregestation lead-exposed group (n = 8) (mothers of these rats were exposed to 0.2% lead acetate in the drinking water for one month before conception), (c) gestation lead-exposed group (n = 8) (exposed to 0.2% lead acetate in the drinking water through the mother throughout gestation [gestation day 01 to day 21]), (d) lactation lead-exposed group (n = 8) (exposed to 0.2% lead acetate in the drinking water through the mother throughout lactation [postnatal day 01 to day 21]) and (e) gestation and lactation lead-exposed group (n = 8) (exposed to 0.2% lead acetate throughout gestation and lactation). On postnatal day 30, rat pups of all the groups were killed. Numbers of surviving neurons in the hippocampus, amygdala and cerebellum regions were counted using cresyl violet staining technique. Histological data indicate that lead exposure caused significant damage to neurons of hippocampus, amygdala and cerebellum regions in all lead-exposed groups except lactation lead-exposed group. The extent of damage to neurons of hippocampus, amygdala and cerebellum regions in lactation lead-exposed group was comparable to gestation and lactation groups even though the duration of lead exposure was much less in lactation lead-exposed group. To conclude, the postnatal period of brain development seems to be more vulnerable to lead neurotoxicity compared to prenatal period of brain development. © The Author(s) 2014.

A greater understanding of the key molecules associated with embryo development during human-assisted reproduction is imperative for the development of advanced diagnostics. Previous studies have shown that follicular microRNAs (miRNAs) are reliable markers of the polycystic ovarian syndrome (PCOS). Leveraging the utility of miRNAs in PCOS, the aim of this study was to identify miRNAs in human granulosa cells that may be indicative of blastocyst development. Granulosa cells and oocytes were collected from the first follicle aspirated from patients undergoing oocyte retrieval for in vitro fertilization or intracytoplasmic sperm injection. The development of isolated oocytes was recorded, and granulosa cell samples in this study were separated as follows. Group 1-BLAST: granulosa cells from follicles containing an oocyte that fertilized and developed into a blastocyst, and Group 2-FERT: granulosa cells from oocytes that fertilized but failed to reach blastocyst. A panel of 84 miRNAs, related to development and cellular differentiation, was assessed between the two groups using a miScript PCR array. Fourteen miRNAs and one snoRNA were differentially expressed between the groups. In addition, two downstream candidate protein biomarkers, ATRX and AVEN, were also found to be differentially expressed between the groups. The findings of this pilot study reveal follicular abnormalities on a molecular level, which may affect oocyte competence and its potential to develop successfully as an embryo. We encourage additional studies to confirm and expand on our findings and to determine the usefulness of granulosa-borne miRNAs, ATRX, and AVEN as biomarkers. © 2018 Wiley Periodicals, Inc.

2002-01-01

Two different vaccination protocols were compared with regard to the development of hypertrophic osteodystrophy (HOD) (also termed metaphyseal osteopathy) and effectiveness of immunisation in a litter of 10 Weimaraner puppies. Five puppies (group 1) were vaccinated with a modified live canine parvovirus vaccine (CPV) and then two weeks later with a trivalent vaccine containing modified live canine distemper virus and adenovirus type 2 combined with a Leptospira bacterin (DHL). The CPV and DHL vaccine protocols were administered a further two times, at two-week intervals. Group 2 was vaccinated with three consecutive multivalent vaccines containing modified live canine distemper virus, canine parvovirus, parainfluenza and adenovirus type 2 combined with a Leptospira bacterin, at four-week intervals. All puppies were first vaccinated at the age of eight weeks. Three dogs in group 1 developed HOD, while all five dogs in group 2 developed HOD during the study period. Dogs in group 2 had more episodes of HOD than those in group 1. Dogs in group 1 developed higher antibody titres to canine distemper virus and parvovirus compared with those in group 2. Only two out of the 10 dogs developed protective antibody titres to parvovirus. The results of this study suggest that the two different vaccination protocols affected the pattern of appearance of HOD and immunisation in this litter of Weimaraner puppies. The results obtained and the previously reported data suggest that a larger controlled study is needed to further elucidate the effect of different vaccination protocols on HOD and immunisation in Weimaraner puppies.

2013-11-01

An Erb's Engram is a common debility that develops in recovering children with Erb's palsy. The purpose of this study was to investigate the effect of kinesiotaping over the deltoid and the forearm on the development of proper upper extremity function in children recovering from Erb's palsy. Thirty patients with Erb's palsy participated for 3 months in this study and were equally divided into two groups; control group A and study group B. The two groups received the same designed physical therapy program, while group B along the program, received kinesiotaping over the deltoid and the forearm. The subjects were evaluated, pre and post-treatment, and scored functionally, using the Toronto Active Motion Scale, and objectively, using an EMG device utilized to obtain the percentages of degeneration of the deltoid and the biceps muscles. Post-treatment values of six out of nine measured variables, between the two groups, revealed significant difference in favor of group B. The obtained results strongly support the introduction of kinesiotaping of the deltoid and the forearm as an adjunct to the treatment program of Erb's palsied children.

Older but wilier: In-group accountability and the development of subjective group dynamics.

PubMed

Abrams, Dominic; Rutland, Adam; Cameron, Lindsey; Ferrell, Jennifer

2007-01-01

To test social and cognitive variables that may affect the development of subjective group dynamics, the authors had 224 children between the ages of 5 and 12 years evaluate an in-group and an out-group and normative and deviant in-group members under conditions of high or low accountability to in-group peers. In-group bias and relative favorability to normative versus deviant in-group members (differential evaluation) increased when children were accountable to peers and as a function of perceptions of peer group acceptance of these members (differential inclusion). These effects were significantly larger among older children. Multiple classification ability was unrelated to judgments of group members. This study shows that the development of subjective group dynamics involves an increase in sensitivity to the normative aspects of the intergroup context. Copyright 2006 APA, all rights reserved.

A descriptive study of lexical organisation in bilingual children with language impairment: Developmental changes.

Holmström, Ketty; Salameh, Eva-Kristina; Nettelbladt, Ulrika; Dahlgren Sandberg, Annika

2016-04-01

This study aimed to describe the development of Arabic and Swedish lexical organisation in bilingual children with language impairment (BLI). Lexical organisation was assessed through word associations in 10 BLI and 10 bilingual children with typical development (BTD), aged 6;2-8;0 years, matched for age and gender. The participants were assessed twice, with a 1-year interval. Word associations were coded as paradigmatic, syntagmatic, phonological, other and no answer. This study reports analyses of the semantically-related syntagmatic and paradigmatic associations. Using repeated measures ANOVA, main and interaction effects of Group, Time and Language were examined for paradigmatic and syntagmatic associations separately. The interaction between Group and Time was significant for both associations. The BLI group increased syntagmatic associations from time 1 to time 2, while the BTD group increased paradigmatic associations. Results showed a significant main effect of Language for both types of associations, with better performance in Swedish. Significant Group by Language interactions resulted from lower Arabic than Swedish syntagmatic and paradigmatic scores for the BLI and BTD groups, respectively. Differing developmental trajectories indicate that bilingual children with LI develop lexical organisation at a slower pace than bilingual peers with typical language development.

2017-04-01

This study was done to develop a children's sex education program for the parents of lower elementary grade students and to evaluate its effects on sexual knowledge, gender role attitude, parent efficacy for child's sex education, and marital consistency. A quasi-experimental with a non-equivalent control group pretest-posttest design was used. The participants were 29 couples (58 parents, experimental group=28, control group=30) from G city. The 5-week (5-session) program was developed based on 'A theory of protection: parents as sex educators' and used the case-based small group learning method. Data were collected during July and August 2015. The characteristics of the program developed in the present study were a theoretical-based, client-centered, multi-method. After the intervention, the experimental group showed a significant improvement in sexual knowledge, gender role attitudes, parent efficacy for child's sex education, and marital consistency, compared to the control group. The effect sizes of the program were .64 (knowledge), .65 (gender role attitudes), and .68 (parent efficacy). The results of this study provided implications for the parents as effective sex educator and the role expansion of school health nurses. © 2017 Korean Society of Nursing Science

The use of core outcome sets (COS) ensures that researchers measure and report those outcomes that are most likely to be relevant to users of their research. Several hundred COS projects have been systematically identified to date, but there has been no formal quality assessment of these studies. The Core Outcome Set-STAndards for Development (COS-STAD) project aimed to identify minimum standards for the design of a COS study agreed upon by an international group, while other specific guidance exists for the final reporting of COS development studies (Core Outcome Set-STAndards for Reporting [COS-STAR]). An international group of experienced COS developers, methodologists, journal editors, potential users of COS (clinical trialists, systematic reviewers, and clinical guideline developers), and patient representatives produced the COS-STAD recommendations to help improve the quality of COS development and support the assessment of whether a COS had been developed using a reasonable approach. An open survey of experts generated an initial list of items, which was refined by a 2-round Delphi survey involving nearly 250 participants representing key stakeholder groups. Participants assigned importance ratings for each item using a 1-9 scale. Consensus that an item should be included in the set of minimum standards was defined as at least 70% of the voting participants from each stakeholder group providing a score between 7 and 9. The Delphi survey was followed by a consensus discussion with the study management group representing multiple stakeholder groups. COS-STAD contains 11 minimum standards that are the minimum design recommendations for all COS development projects. The recommendations focus on 3 key domains: the scope, the stakeholders, and the consensus process. The COS-STAD project has established 11 minimum standards to be followed by COS developers when planning their projects and by users when deciding whether a COS has been developed using reasonable methods.

Functional magnetic resonance imaging of story listening in adolescents and young adults with Down syndrome: evidence for atypical neurodevelopment.

Previous studies have documented differences in neural activation during language processing in individuals with Down syndrome (DS) in comparison with typically developing individuals matched for chronological age. This study used functional magnetic resonance imaging (fMRI) to compare activation during language processing in young adults with DS to typically developing comparison groups matched for chronological age or mental age. We hypothesised that the pattern of neural activation in the DS cohort would differ when compared with both typically developing cohorts. Eleven persons with DS (mean chronological age = 18.3; developmental age range = 4-6 years) and two groups of typically developing individuals matched for chronological (n = 13; mean age = 18.3 years) and developmental (mental) age (n = 12; chronological age range = 4-6 years) completed fMRI scanning during a passive story listening paradigm. Random effects group comparisons were conducted on individual maps of the contrast between activation (story listening) and rest (tone presentation) conditions. Robust activation was seen in typically developing groups in regions associated with processing auditory information, including bilateral superior and middle temporal lobe gyri. In contrast, the DS cohort demonstrated atypical spatial distribution of activation in midline frontal and posterior cingulate regions when compared with both typically developing control groups. Random effects group analyses documented reduced magnitude of activation in the DS cohort when compared with both control groups. Activation in the DS group differed significantly in magnitude and spatial extent when compared with chronological and mental age-matched typically developing control groups during a story listening task. Results provide additional support for an atypical pattern of functional organisation for language processing in this population. © 2013 MENCAP and International Association of the Scientific Study of Intellectual and Developmental Disabilities and John Wiley & Sons Ltd.

This study's objective was to develop and test a smartphone app that supports learning and using coping skills for managing tinnitus. The app's content was based on coping skills that are taught as a part of progressive tinnitus management (PTM). The study involved three phases: (1) develop a prototype app and conduct usability testing; (2) conduct two focus groups to obtain initial feedback from individuals representing potential users; and (3) conduct a field study to evaluate the app, with three successive groups of participants. Participants were adults with bothersome tinnitus. For Phase 2, two focus groups were attended by a total of 17 participants. Phase 3 involved three consecutive rounds of participants: five from the focus groups followed by two rounds with 10 participants each who had not seen the app previously. In both the focus groups and field studies, participants responded favourably to the content. Certain features, however, were deemed too complex. Completion of this project resulted in the development and testing of the delivery of PTM coping skills via a smartphone app. This new approach has the potential to improve access to coping skills for those with bothersome tinnitus.

2009-04-01

We report a cross-syndrome comparison of the development of holistic processing in face recognition in school-aged children with developmental disorders: autism, Down syndrome, and Williams syndrome. The autism group was split into two groups: one with high-functioning children and one with low-functioning children. The latter group has rarely been studied in this context. The four disorder groups were compared with typically developing children. Cross-sectional trajectory analyses were used to compare development in a modified version of Tanaka and Farah's part-whole task. Trajectories were constructed linking part-whole performance either to chronological age or to several measures of mental age (receptive vocabulary, visuospatial construction, and the Benton Facial Recognition Test). In addition to variable delays in onset and rate of development, we found an atypical profile in all disorder groups. These profiles were atypical in different ways, indicating multiple pathways to, and variable outcomes in, the development of face recognition. We discuss the implications for theories of face recognition in both atypical and typical development, including the idea that part-whole and rotation manipulations may tap different aspects of holistic and/or configural processing.

Examining Equivalence of Concepts and Measures in Diverse Samples

2012-01-01

While there is growing awareness for the need to examine the etiology of problem behaviors across cultural, racial, socioeconomic, and gender groups, much research tends to assume that constructs are equivalent and that the measures developed within one group equally assess constructs across groups. The meaning of constructs, however, may differ across groups or, if similar in meaning, measures developed for a given construct in one particular group may not be assessing the same construct or may not be assessing the construct in the same manner in other groups. The aims of this paper were to demonstrate a process of testing several forms of equivalence including conceptual, functional, item, and scalar using different methods. Data were from the Cross-Cultural Families Project, a study examining factors that promote the healthy development and adjustment of children among immigrant Cambodian and Vietnamese families. The process described in this paper can be implemented in other prevention studies interested in diverse groups. Demonstrating equivalence of constructs and measures prior to group comparisons is necessary in order to lend support of our interpretation of issues such as ethnic group differences and similarities.

Immunological changes at rectal mucosa in appendectomised subjects and inhabitants of developing countries.

2007-02-01

It has been suggested that appendicitis protects against ulcerative colitis. We hypothesize that early poor hygiene protects against ulcerative colitis (UC) and predisposes to appendicitis. Our aim was to elucidate the immunological characteristics of rectal mucosa in two populations protected against UC development: appendectomised subjects and inhabitants of developing countries. this was an age-matched prospective case-control study. Each consecutive individual case appendectomised (group A) was compared to another control from a developing country (group B) and to a control from the general population (group C). Four biopsies from rectal mucosa were taken from all subjects, two for histological and two for histochemical study; specific antibodies were used for T lymphocytes CD3+, CD4+, CD8+ and B lymphocytes CD20+ populations. Mucosa samples of 45 non-smoker healthy subjects were studied, of which 15 were from group A, 15 from group B and 15 from group C. In appendectomised subjects, the proportion of CD8+ cells was higher than in the control group (p<0.001), but similar to that in B group. The proportion of CD3+ and CD20+ cells was significatively lower than in Ecuadorians, but similar to the control group. In Ecuadorians, the proportion of CD3+ and CD8+ cells was significatively higher than in the control group (p<0.001), and were similar to that of CD20+. There were no significant differences in the proportion of CD4+. Appendectomy and deficient environmental hygiene are associated with an increase of CD8+ T lymphocytes in the rectal mucosa. Moreover, deficient environmental hygiene is associated with an increase of CD3+ and CD8+ lymphocytes. The CD8+ increase is the only common significant alteration in the mucosa of both groups protected against the development of ulcerative colitis, suggesting that the factors causing changes in lamina propria lymphocytes of both groups are different.

2010-05-01

Perceptual grouping has traditionally been thought to be governed by innate, universal principles. However, recent work has found differences in Japanese and English speakers' non-linguistic perceptual grouping, implicating language in non-linguistic perceptual processes (Iversen, Patel, & Ohgushi, 2008). Two experiments test Japanese- and English-learning infants of 5-6 and 7-8 months of age to explore the development of grouping preferences. At 5-6 months, neither the Japanese nor the English infants revealed any systematic perceptual biases. However, by 7-8 months, the same age as when linguistic phrasal grouping develops, infants developed non-linguistic grouping preferences consistent with their language's structure (and the grouping biases found in adulthood). These results reveal an early difference in non-linguistic perception between infants growing up in different language environments. The possibility that infants' linguistic phrasal grouping is bootstrapped by abstract perceptual principles is discussed. Copyright 2010 Elsevier B.V. All rights reserved.

The Helpfulness of Spiritually Influenced Group Work in Developing Self-Awareness and Self-Esteem: A Preliminary Investigation

PubMed Central

Coholic, Diana

2005-01-01

This paper discusses an exploratory study that investigated the helpfulness of spiritually influenced group work with eight adult women who shared a history of substance abuse. The overall purpose of the group was to help participants develop their self-awareness and self-esteem. The group, which was contextualized in transpersonal theory, was organized around the following themes and experiential exercises: meditation, mindfulness practice, dream work, stream of consciousness writing, the shadow self, and other arts-based processes. Grounded-theory analysis of group sessions and individual interviews with the participants found that the participants perceived the group to be helpful in developing their self-awareness and self-esteem. While the participants identified different aspects of the group as spiritual, making-meaning was one practice that was consistently described as a spiritually sensitive process. The results of this study in this emergent field are promising and suggestions are provided for future research. PMID:16200326

Gestational diabetes mellitus (GDM) is a common condition that is defined as glucose intolerance of varying degree with onset or first recognition during pregnancy and it affects approximately 5% of all pregnancies all over the world. GDM is not only associated with adverse pregnancy outcomes such as macrosomia, dystocia, birth trauma, and metabolic complications in newborns, but it is also a strong predictor of transitioning to overt DM postpartum. The association of ABO blood groups with DM has been observed before in several epidemiological and genetic studies and resulted with inconsistent findings, but still there are not enough studies in the literature about the association of ABO blood groups with GDM. In this study, we aimed at investigating any possible relationship between the ABO blood group system and GDM and also the transitioning of GDM to overt DM postpartum, in Turkey. A total of 233 patients with GDM from Kayseri Training and Research Hospital between 2002 and 2012 were included in the study. The cases that have serologically determined blood groups and Rh factor in the hospital records were included in the study, and the patients with unknown blood groups were excluded. Patients were classified according to blood groups (A, B, AB, and O) and Rh status (+/-). GDM was diagnosed based on the glucose cut-points of the International Association of the Diabetes and Pregnancy Society Groups. The distributions of blood groups of the patients with GDM were compared with the distribution of blood groups of 17,314 healthy donors who were admitted to the Turkish Red Crescent Blood Service in our city in 2012. There was a significant difference between the patients with GDM and control group in terms of distribution of ABO blood groups. Blood group AB was found to be higher in the patients with GDM compared to the control group (P=0.029). When the patients were compared according to the development of DM, the ratio of group O was higher than others, while the ratio of group B was lower in the group developing DM (P=0.001). There was a significant difference between the groups - GDM patients with or without DM - in terms of distribution of ABO blood groups with Rh factor and the ratio of developing DM is found to be higher in patients with +Rh factor among all the blood groups except for group B (P=0.008). In this study, we found a higher risk of GDM for the patients with blood group AB, which means that we have to be more careful on the follow-up of pregnant women with blood group AB. The patients with GDM of blood group O are under a higher risk of developing DM and also +Rh factor must be considered as another risk factor, so these patients should be closely followed postpartum by the oral glucose tolerance tests. To our knowledge, this is the first analysis that investigates the association between the ABO blood groups and transitioning to DM after GDM.

Improving in vitro maturation could increase the rate of pregnancy from oocytes matured in vitro. Consequently, patients will be prevented from using gonadotropin with its related side effects. In this study, the maturation medium was enriched by platelet lysate (PL), then maturation and subsequent developments were monitored. Oocytes at germinal vesicle stage with cumulus cells (cumulus-oocyte complex) and without cumulus cells (denuded oocytes) were obtained from mature female mice. The maturation medium was enriched by 5 and 10 % PL and 5 % PL + 5 % fetal bovine serum (FBS) as experimental groups; the control groups' media consisted of 5 and 10 % FBS. After 18 h, the matured oocytes were collected and, after fertilization, subsequent development was monitored. The rates of maturation, fertilization and 2-cell embryo development for the denuded oocyte groups in experimental media 5 % PL and 5 % PL + 5 % FBS were significantly higher than those of the control groups ( P < 0.05), while the results for the cumulus-oocyte complex groups were similar between the experimental groups and control groups. The results of this study indicated that platelet lysate could improve the maturation rate in the absence of granulosa cells compared to media with FBS. This extract also had positive effects on fertilization and embryo development.

We set out to determine which patients admitted for expectant management of early onset severe pre-eclampsia develop abruptio placentae and to compare the perinatal mortality rate of patients who developed abruptio placentae with those who did not have this complication. This was a case controlled study, using gestational age at delivery to select a control group for 69 patients who developed abruptio placentae. The only significant difference on admission was the higher uric acid levels in patients who developed abruptio placentae. Mean admission to delivery intervals were 11.9 and 8.8 days for the control and abruption groups respectively (P = 0.0083). Fifty-eight per cent of the babies in the abruptio placentae group developed late decelerations, as determined by fetal heart rate monitoring compared with 32% in the control group. Lactate dehydrogenase levels before delivery were significantly higher in the abruption group, but it only became elevated shortly before delivery and in the minority of cases. There were two intrauterine and four neonatal deaths in the abruption group and two neonatal deaths in the control group. Late decelerations detected by frequent fetal heart rate monitoring in patients with early onset severe pre-eclampsia is the only early warning of abruptio placentae.

To investigate the efficacy of dornase alpha, a mucolytic agent, in children who developed pulmonary atelectasis after congenital heart surgery. Retrospective case-control study. Paediatric cardiac intensive care unit at a tertiary care hospital. Between July, 2011 and July, 2012, 41 patients who underwent congenital cardiac operations and developed post-operative pulmonary atelectasis that was resistant to conventional treatment and chest physiotherapy. In all, 26 patients received dornase alpha treatment. As a control group, 15 patients were treated with conventional medications and chest physiotherapy. The median age of patients was 25.5 (3-480) days in the study group and 50.0 (3-480) days in the control group. A total of 15 (57.6%) patients in the study group and 8 (53.3%) patients in the control group were male. The median weight was 4.2 (2.9-14.2) kg and 4.0 (3.5-13.6) kg in the study and control group, respectively. In the study group, pulmonary atelectasis was diagnosed at a median period of 5 (2-18) days after operations, whereas in the control group atelectasis was diagnosed at a median period of post-operative 6 (3-19) days. In the study group, the median atelectasis score decreased from 3.4 (1-6) to 0.8 (0-3) (p = 0.001). The median pO2 level increased from 69 (17-142) mmHg to 89 (30-168) mmHg (p = 0.04). In addition, heart rate and respiratory rate per minute were significantly decreased (p < 0.05). There were no significant changes in these parameters in the control group. The use of dornase alpha can be effective for the management of pulmonary atelectasis that develops following congenital heart surgery.

The aim of the study was to determine the effect of football school program and physical education curriculum on changes in the motor abilities of 7- and 8-year-old boys. The study included a sample of 180 boys divided into group 1 (7-year-old boys), subdivided to experimental (n = 40) and control (n = 50) groups, and group 2 (8-year-old boys), subdivided to experimental (n = 40) and control (n = 50) groups. Experimental groups included children attending three training units of football training over a 9-month period, in addition to the conventional physical education curriculum. Control groups included children attending only conventional physical education curriculum. All study subjects underwent testing with a battery of 12 motor tests at the beginning and at the end of the study. Results obtained by discriminative canonic analysis showed no statistically significant between-group difference in motor abilities at the beginning of the study. However, significant differences in favor of experimental groups were recorded at the end of the study. Favorable changes in all motor variables were observed in both experimental and control groups of children from the initial through the final state. These changes were more pronounced in experimental groups. Analysis of variance for difference variables (final to initial measurement) indicated programmed education in the form of football training in addition to regular physical education curriculum to predominantly influence the development of aerobic endurance, agility, speed and flexibility in 7-year-old boys, and of explosive strength, aerobic endurance, flexibility and speed in 8-year-old boys. In the latter, football training led to the formation of a motor complex integrating explosiveness, speed, coordination, endurance and flexibility as a general motor factor determining future quality development in football.

Purpose The purpose of this study was to assess if a clinical group practice model has an impact on enhancing the interpersonal skills of predoctoral dental students, what factors may influence the development of these skills, and what, if any, are innovative and technological solutions that can potentially influence interpersonal skills in predoctoral dental students. Methods This study surveyed the faculty responsible for teaching the dental students in a recently developed group practice model. Out of 18 eligible group practice leaders at one US dental school, 17 respondents (94.4%) completed the survey. In addition, this study asked the faculty to provide qualitative response and recommendations to improve interpersonal skills. Based on the feedback, a focus group was conducted to explore opportunities to further enhance the skills. Results The results of the study suggest that the group practice model has a positive and distinct impact on the development of overall interpersonal skills for students. Further research suggests that the greatest impacted areas of personal development are critical thinking skills and teamwork. However, as a way to make the model more effectual, most faculty suggested the need for additional time, for both students and faculty. To some extent, using technology and innovative teaching pedagogies could potentially address the challenge of limited time. Conclusion Based on the results of the survey, one may conclude that with adequate design and conditions, the group practice model can have a positive effect on the interpersonal skills of its students.

The aim of this study was to evaluate the effects of the Professional Identity Development Program on the professional identity, job satisfaction and burnout levels of registered nurses. This study was conducted as a quasi-experimental one with 63 nurses working in a university hospital. Data were gathered using the Personal Information Questionnaire, the Professional Self Concept Inventory, Minnesota Job Satisfaction Inventory and the Maslach Burnout Inventory. The Professional Identity Development Program which consists of ten sessions was implemented to the study group once a week. The Program significantly improved the professional identity of the nurses in the study group compared to that of the control group. During the research period, burnout levels significantly decreased in the study group while those of the control group increased. The programme did not create any significant differences in the job satisfaction levels of the nurses. The programme had a positive impact on the professional identity of the nurses. It is recommended that the programme should be implemented in different hospitals with different samples of nurses, and that its effectiveness should be evaluated. © 2014 Wiley Publishing Asia Pty Ltd.

The purpose of this study was to investigate the effect of self-testing activities on the development of fundamental movement skills in first-grade children in Greece. Two groups of children were tested. The Control group (n = 23 children) received the regular 12-wk. physical education school program and the Experimental group (n = 22 children) received a 12-wk. skill-oriented program with an increasing allotment of self-testing activities. The Test of Gross Motor Development was used to assess fundamental movement skills, while the content areas of physical education courses were estimated with an assessment protocol, based on the interval recording system called the Academic Learning Time-Physical Education. A 2 x 2 repeated measures analysis of variance with group as the between factor and testing time (pretest vs posttest) as the repeated-measures factor was performed to assess differences between the two groups. A significant interaction of group with testing time was found for the Test of Gross Motor Development total score, with the Experimental group scoring higher then the Control group. A significant main effect was also found for test but not for group. This study provides evidence supporting the notion that a balanced allotment of the self-testing and game activities beyond the usual curriculum increases the fundamental motor-skill development of children. Also, it stresses the necessity for content and performance standards for the fundamental motor skills in educational programs. Finally, it seems that the Test of Gross Motor Development is a useful tool for the assessment of children's fundamental movement skills.

The General University Requirements (GUR) at The Hong Kong Polytechnic University (PolyU) is an integral part of the new 4-year undergraduate curriculum which attempts to promote holistic student development. To evaluate the effectiveness of the GUR, a study adopting a static group comparison design was conducted, with a sample of Year 3 PolyU students studied in the 4-year undergraduate degree program (n=566) compared with a control Year 3 sample recruited from a comparable university in Hong Kong (n=285). The students in both samples responded to measures on empathy, positive youth development, and engagement in university study. Results showed that although both groups basically did not differ in the major background demographic variables, PolyU students performed better than did the students of the control group on measures of holistic development. Bearing in mind the intrinsic problems of the static comparison group design, the present findings provide support for the effectiveness of the GUR at PolyU.

This study was conducted to develop and test the effects of a motivational interviewing self-management program for use with elderly patients with diabetes mellitus. A non-equivalent control group pretest-posttest design was used. The participants were 42 elderly diabetic patients (experimental group: 21, control group: 21). The motivational interviewing self-management program for elders with diabetes mellitus developed in this study consisted of a 12-week program in total (8 weeks for group motivational interviewing and education and 4 weeks for individual motivational interviewing on the phone). Data were collected between February 13 and May 3, 2013 and were analyzed using t-test, paired t-test, and repeated measure ANOVA with SPSS/WIN 18.0. For the experimental group, significant improvement was found for self-efficacy, self-care behavior, glycemic control and quality of life (daily life satisfaction, influence of disease) as compared to the control group. The study findings indicate that the motivational interviewing self-management program is effective and can be recommended as a nursing intervention for elderly patients with diabetes mellitus.

Relationships between early motor development and language and reading skills were studied in 154 children, of whom 75 had familial risk of dyslexia (37 females, 38 males; at-risk group) and 79 constituted a control group (32 females, 47 males). Motor development was assessed by a structured parental questionnaire during the child's first year of life. Vocabulary and inflectional morphology skills were used as early indicators of language skills at 3 years 6 months and 5 years or 5 years 6 months of age, and reading speed was used as a later indicator of reading skills at 7 years of age. The same subgroups as in our earlier study (in which the cluster analysis was described) were used in this study. The three subgroups of the control group were 'fast motor development', 'slow fine motor development', and 'slow gross motor development', and the two subgroups of the at-risk group were 'slow motor development' and 'fast motor development'. A significant difference was found between the development of expressive language skills. Children with familial risk of dyslexia and slow motor development had a smaller vocabulary with poorer inflectional skills than the other children. They were also slower in their reading speed at the end of the first grade at the age of 7 years. Two different associations are discussed, namely the connection between early motor development and language development, and the connection between early motor development and reading speed.

To evaluate the rehospitalization rates of premature infants who received palivizumab prophylaxis and its influence on the growth and development of these infants. Infants with a gestational age of less than 32 weeks were randomized to receive prophylaxis with palivizumab (study group) or nothing (control group). Nasal swab samples were obtained monthly in all cases and also in case of infection and hospitalization. At the corrected age of 18 months Guide for Monitoring Child Development (GMCD) was administered to all patients and anthropometric indices were evaluated. The study was completed with 39 infants in the study group and 40 infants in the control group. Incidence of hospitalization due to respiratory syncitial virus (RSV) was found to be significantly lower in the study group both at the year of prophylaxis and in the following year (p = 0.001, odds ratio 1.32 [1.11-1.57]). There were no significant differences in terms of anthropometric indices or GMCD tests between the groups at the corrected age of 18 months. Palivizumab reduced the incidence of lower respiratory tract infections and hospitalizations due to RSV both in the year of prophylaxis and in the following year. However, this decrease did not have any impact on the development of infants. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Preparing new graduate nurses (NGNs) to achieve standards of nursing competence is challenging; therefore, this study developed and evaluated the effects of a 10-minute preceptor (10MP) model for assisting NGNs in their professional development and increasing their retention in hospitals. A repeated-measures design study, with an intervention and a two-group comparison, was conducted. A total of 107 NGNs participated in the study. At day 7, work stress and work experience were moderately high for the NGNs in both the 10MP and traditional preceptor model (TPM) groups. The preceptorship program showed significant differences between groups (p = 0.001) regarding work stress at months 2 and 3 and work experience at months 1, 2, and 3. The 10MP group reported lower turnover intention and higher satisfaction with the preceptors than the TPM group. The 10MP model is effective at improving training outcomes and facilitating the professional development of NGNs. Copyright 2015, SLACK Incorporated.

An Erb’s Engram is a common debility that develops in recovering children with Erb’s palsy. The purpose of this study was to investigate the effect of kinesiotaping over the deltoid and the forearm on the development of proper upper extremity function in children recovering from Erb’s palsy. Thirty patients with Erb’s palsy participated for 3 months in this study and were equally divided into two groups; control group A and study group B. The two groups received the same designed physical therapy program, while group B along the program, received kinesiotaping over the deltoid and the forearm. The subjects were evaluated, pre and post-treatment, and scored functionally, using the Toronto Active Motion Scale, and objectively, using an EMG device utilized to obtain the percentages of degeneration of the deltoid and the biceps muscles. Post-treatment values of six out of nine measured variables, between the two groups, revealed significant difference in favor of group B. The obtained results strongly support the introduction of kinesiotaping of the deltoid and the forearm as an adjunct to the treatment program of Erb’s palsied children. PMID:25685456

Objective: To study the effect of family integrated care (FIC) in neonatal intensive care unit (NICU) to the development of preterm infants at 18 months of age. Method: This is a prospective parallel case-control study. Infants in FIC group were preterm infants enrolled in previous FIC study with gestational age (GA) 28-35 weeks. Study period was from July 2015 to July 2016. Subjects were all enrolled from Department of Child Healthcare in the Third Xiangya Hospital of Central South University. Infants in control group were gender, birth weight (BW), BW percentile and days of life (DOL) at follow-up matched (1∶1 ratio) preterm infants who did not enter FIC in NICU. The age at follow-up was 18 months. Study parameters were maternal education year, socioeconomic status (SES) by Graffar method, home observation for measurement of the environment (HOME), mental development index (MDI) and psychomotor development index (PDI) by mental and psychomotor Bayley scales of infant development (BSID). SPSS 20.0 of χ 2 test, t test, Pearson coefficient test and Spearman coefficient test were used for the statistical analysis. Result: Totally 67 infants were enrolled in each of FIC group and control group, with percentage of male gender 52% (35 infants) and 51% (34 infants), representatively. GA of FIC group and control group was (32.4±1.7) and (32.2±1.6) weeks, BW was (1 690±415) and (1 719±412) g. Weight at 18 months follow-up was (10±1) and (10±1) kg, maternal education year was (15±2) and (15±2) years, SES was (42±6) and (41±6) score, HOME was (31±5) and (32±5) score, representatively. There was no significant difference between FIC group and control group in the above parameters, making these 2 groups comparable. The MDI and PDI of FIC group were significantly higher than those of control group ((95±9) vs . (86±9), (87±9) vs . (80±8) score, t =5.506, 4.502, both P =0.000). The MDI and PDI of all groups were positively correlated to GA ( r =0.398 and 0.272, P =0.000 and 0.001), but the difference of MDI or PDI between FIC group and control group was not related to GA ( r =0.679 and -0.393, P =0.094 and 0.383). Conclusion: FIC in NICU is beneficial to the development of preterm infants at 18 months of age. It is worthwhile to promote FIC in NICU in China.

The purpose of this study was to investigate the use of MRI in predicting prostate growth and development. A total of 1,500 healthy male volunteers who underwent MRI of the pelvis were included in this prospective study. Subjects were divided into five groups according to age (group A, 2-5 years; group B, 6-10 years; group C, 11-15 years; group D, 16-20 years; group E, 21-25 years). Total prostate volume (TPV) as well as prostate central zone (CZ) and peripheral zone (PZ) were measured and evaluated on MRI. Data of the different groups were compared using variance analysis, Scheffé's method, Kruskal-Wallis H-test, and Pearson's correlation. Statistical significance was inferred at P < 0.05. In groups A and B, the prostates were barely visible. In group C, although TPV was measured, it was hard to distinguish CZ and PZ. In group D, 136 CZ and PZ were clearly visible. In group E, 377 CZ and PZ were clearly visible on T2-weighted imaging (T2WI). The median TPVs of groups A, B, C, D, and E were 0.00 cm(3), 0.05 cm(3), 2.83 cm(3), 8.32 cm(3,) and 11.56 cm(3), respectively, and the median prostate development scores were 0.08, 0.69, 1.56, 2.38, and 2.74, respectively. Both TPVs and zonal anatomy scores varied significantly among the five groups (P = 0.000). TPV and zonal anatomy score increased with increasing age. MRI provides a reliable quantitative reference for prostate growth and development. • When and how the prostate develops after birth remains unclear. • Prostate volume increases rapidly after the age of 10 years. • MRI provides a reliable objective and quantitative reference for prostate growth and development.

Introduction The increasing scientific evidence of various health hazards on exposure of Radiofrequency Radiation (RFR) emitted from both the cell phones and base stations have caused significant media attention and public discussion in recent years. The mechanism of interaction of RF fields with developing tissues of children and fetuses may be different from that of adults due to their smaller physical size and variation in tissue electromagnetic properties. The present study may provide an insight into the basic mechanisms by which RF fields interact with developing tissues in an embryo. Aim To evaluate the possible tissue and DNA damage in developing liver of chick embryo following chronic exposure to Ultra-High Frequency/Radiofrequency Radiation (UHF/RFR) emitted from 2G and 3G cell phone. Materials and Methods Fertilized chick embryos were incubated in four groups. Group A-experimental group exposed to 2G radiation (60 eggs), Group B- experimental group exposed to 3G radiation (60 eggs), Group C- sham exposed control group (60 eggs) and Group D– control group (48 eggs). On completion of scheduled duration, the embryos were collected and processed for routine histological studies to check structural changes in liver. The nuclear diameter and karyorrhexis changes of hepatocytes were analysed using oculometer and square reticule respectively. The liver procured from one batch of eggs from all the four groups was subjected to alkaline comet assay technique to assess DNA damage. The results were compared using one-way ANOVA test. Results In our study, the exposure of developing chick embryos to 2G and 3G cell phone radiations caused structural changes in liver in the form of dilated sinusoidal spaces with haemorrhage, increased vacuolations in cytoplasm, increased nuclear diameter and karyorrhexis and significantly increased DNA damage. Conclusion The chronic exposure of chick embryo liver to RFR emitted from 2G and 3G cell phone resulted in various structural changes and DNA damage. The changes were more pronounced in 3G experimental group. Based on these findings it is necessary to create awareness among public about the possible ill effects of RFR exposure from cell phone.

This study was done to develop and evaluate a drug dosage calculation training program using cognitive loading theory based on a smartphone application. Calculation ability, dosage calculation related self-efficacy and anxiety were measured. A nonequivalent control group design was used. Smartphone application and a handout for self-study were developed and administered to the experimental group and only a handout was provided for control group. Intervention period was 4 weeks. Data were analyzed using descriptive analysis, χ²-test, t-test, and ANCOVA with the SPSS 18.0. The experimental group showed more 'self-efficacy for drug dosage calculation' than the control group (t=3.82, p<.001). Experimental group students had higher ability to perform drug dosage calculations than control group students (t=3.98, p<.001), with regard to 'metric conversion' (t=2.25, p=.027), 'table dosage calculation' (t=2.20, p=.031) and 'drop rate calculation' (t=4.60, p<.001). There was no difference in improvement in 'anxiety for drug dosage calculation'. Mean satisfaction score for the program was 86.1. These results indicate that this drug dosage calculation training program using smartphone application is effective in improving dosage calculation related self-efficacy and calculation ability. Further study should be done to develop additional interventions for reducing anxiety.

To study the effect of guava and synthetic vitamin C on the development of gingival inflammation during experimental gingivitis. Participants were randomly assigned to three groups supplemented daily with either 200g guava, 200mg synthetic vitamin C or water. The study included a 14 days pre-experimental period with oral hygiene instructions, scaling, prophylaxis and supplementation. Thereafter, experiment gingivitis was initiated, while continuing supplementation. At baseline, day 7 and day 14 of experimental gingivitis, Plaque Index (PlI) and Gingival Index (GI) were assessed. During the entire study, dietary fruit/vegetables intake was minimal. PlI increased in guava-, vitamin C- and control group (ΔPlI: 1.30, 1.61 and 1.79 respectively). However, the guava group developed significantly less plaque compared to the control group. The GI increase of both guava- and vitamin C group was significantly less than the increase of the control group (ΔGI: 0.10, 0.24 and 0.87 respectively). in a population of young non-smoking adults, consumption of either 200g guava/day or 200mg synthetic vitamin C/day, prior to and during the oral hygiene abstention period, has a preventive effect on the development of experimental gingivitis as compared to the control group that developed the usual amount of experimental gingivitis.

2014-05-01

This study describes a qualitative research design that focuses on nursing students who were aligned to different extra-curricular groups (a student representative committee, a Nurses' Day Committee and a magazine editorial team) within the School of Health. The study explores the nursing students' experiences and perceptions of belonging to an extra-curricular group within a pre-registration nursing course. Data were collected using focus groups. The findings of this study suggest that students who are members of extra-curricular groups perceive group membership to have many positive benefits. The findings were grouped into three main themes namely: employability, retention and personal gain. The findings suggest that students are clearly aware of their career development and expressed how group membership meant they were able to develop skills around employability. Students highlighted that they gained support and built lasting relationships through the groups which supported and reassured them which it was felt enabled them to progress successfully through the course. These themes reinforce the value of having established groups within a pre-registration curriculum. Copyright © 2013 Elsevier Ltd. All rights reserved.

After the Liverpool Care Pathway--development of heuristics to guide end of life care for people with dementia: protocol of the ALCP study.

Davies, N; Manthorpe, J; Sampson, E L; Iliffe, S

2015-09-02

End of life care guidance for people with dementia is lacking and this has been made more problematic in England with the removal of one of the main end of life care guidelines which offered some structure, the Liverpool Care Pathway. This guidance gap may be eased with the development of heuristics (rules of thumb) which offer a fast and frugal form of decision-making. To develop a toolkit of heuristics (rules of thumb) for practitioners to use when caring for people with dementia at the end of life. A mixed-method study using a co-design approach to develop heuristics in three phases. In phase 1, we will conduct at least six focus groups with family carers, health and social care practitioners from both hospital and community care services, using the 'think-aloud' method to understand decision-making processes and to develop a set of heuristics. The focus group topic guide will be developed from the findings of a previous study of 46 interviews of family carers about quality end-of-life care for people with dementia and a review of the literature. A multidisciplinary development team of health and social care practitioners will synthesise the findings from the focus groups to devise and refine a toolkit of heuristics. Phase 2 will test the use of heuristics in practice in five sites: one general practice, one community nursing team, one hospital ward and two palliative care teams working in the community. Phase 3 will evaluate and further refine the toolkit of heuristics through group interviews, online questionnaires and semistructured interviews. This study has received ethical approval from a local NHS research ethics committee (Rec ref: 15/LO/0156). The findings of this study will be presented in peer-reviewed publications and national and international conferences. Published by the BMJ Publishing Group Limited.

The purposes of this study were to: (a) develop a comprehensive communication course combined with a group program for improving communication skills; and (b) examine the effects of the comprehensive communication course on interpersonal communication, relationship change, self-esteem, and depression in nursing students. The experimental group consisted of 82 nursing students, and the control group, 108 nursing students. Both groups each took communication courses from March to June, 2002 and 2003. A group program for improving communication skills was conducted for each 8 subgroups of the experimental group for 90 minutes once a week during the 6 weeks, while the existing communication lecture was conducted for the control group. Both groups were post-tested after the intervention for verifying the difference of variables between the two groups, and the experimental group was also pre-tested for verifying the difference between before and after the treatment. Interpersonal communication score of the post-test in the experimental group was significantly higher than in the control group and the depression score of the post-test in the experimental group was significantly lower than in the control group. Interpersonal communication, relationship change and self-esteem scores were significantly increased and the depression score was significantly decreased in experimental group after the treatment. In conclusion, the comprehensive communication course that was developed in this study had positive effects on communication skills in nursing students.

Development of interactive hypermedia software for high school biology: A research and development study

NASA Astrophysics Data System (ADS)

Alturki, Uthman T.

The goal of this research was to research, design, and develop a hypertext program for students who study biology. The Ecology Hypertext Program was developed using Research and Development (R&D) methodology. The purpose of this study was to place the final "product", a CD-ROM for learning biology concepts, in the hands of teachers and students to help them in learning and teaching process. The product was created through a cycle of literature review, needs assessment, development, and a cycle of field tests and revisions. I applied the ten steps of R&D process suggested by Borg and Gall (1989) which, consisted of: (1) Literature review, (2) Needs assessment, (3) Planning, (4) Develop preliminary product, (5) Preliminary field-testing, (6) Preliminary revision, (7) Main field-testing, (8) Main revision, (9) Final field-testing, and (10) Final product revision. The literature review and needs assessment provided a support and foundation for designing the preliminary product---the Ecology Hypertext Program. Participants in the needs assessment joined a focus group discussion. They were a group of graduate students in education who suggested the importance for designing this product. For the preliminary field test, the participants were a group of high school students studying biology. They were the potential user of the product. They reviewed the preliminary product and then filled out a questionnaire. Their feedback and suggestions were used to develop and improve the product in a step called preliminary revision. The second round of field tasting was the main field test in which the participants joined a focus group discussion. They were the same group who participated in needs assessment task. They reviewed the revised product and then provided ideas and suggestions to improve the product. Their feedback were categorized and implemented to develop the product as in the main revision task. Finally, a group of science teachers participated in this study by reviewing the product and then filling out the questionnaire. Their suggestions were used to conduct the final step in R&D methodology, the final product revision. The primary result of this study was the Ecology Hypertext Program. It considered a small attempt to give students an opportunity to learn through an interactive hypertext program. In addition, using the R&D methodology was an ideal procedure for designing and developing new educational products and material.

Moral Virtue and Practical Wisdom: Theme Comprehension in Children, Youth and Adults

PubMed Central

Narvaez, Darcia; Gleason, Tracy; Mitchell, Christyan

2010-01-01

Three hypotheses were tested about the relation of moral comprehension to prudential comprehension by contrasting comprehension of themes in moral stories with comprehension of themes in prudential stories among third grade, fifth grade and college students (n = 168) in Study 1, and among college students, young and middle aged adults, and older adults (n = 96) in Study 2. In both studies, all groups were statistically significantly better at moral theme comprehension than prudential theme comprehension, suggesting that moral comprehension may develop prior to prudential comprehension. In Study 2, all groups performed equally on moral theme generation whereas both adult groups were significantly better than college students on prudential theme generation. Overall, the findings of these studies provide modest evidence that moral and prudential comprehension each develop separately, and that the latter may develop more slowly. PMID:21171549

PubMed

Saha, N; Saha, D K; Rahman, M A; Aziz, M A; Islam, M K

2012-07-01

This prospective comparative study was conducted with an initial experience in the Department of Pediatric Surgery, Dhaka Shishu (Children) Hospital during the period of December 2007 to January 2009, with the infants of 2-12 weeks age, diagnosed as Hypertrophic pyloric stenosis. Patients selection was done by simple random technique by means of lottery. For open pyloromyotomy conventional method & for laparoscopic pyloromyotomy three trocher techniques was applied. In this study, among 60 cases with infantile hypertrophic pyloric stenosis, 30 cases were finally selected for analysis irrespectively both in laparoscopic (Group A) & in open pyloromyotomy (Group B) group. Patients were studied under variables of operative time, required time of full feeds after operation, post operative hospital stay & both per and post operative complications. Regarding operative time, in Group A, mean±SD operating time (in minutes) was 61.59±51.73 whereas in Group B it was 28.33±8.40 & P value was 0.001. The result was statistically significant. The mean±SD time (in hours) of full feeds (ad libitum) was 35.00±31.70 hours in Group A compared to 28.95±10.99 hours in Group B and P value was found 0.342ns which was not statistically significant. On study of total length (in days) of post operative hospital stay, mean±SD was 3.09±2.25 & 2.58±1.15days in laparoscopic group & open pyloromyotomy group respectively. The p value was 0.355ns, which was statistically insignificant. Again, on study of complications, per operatively 6(19.5%) patients had developed haemorrage, 1(3.33%) had mucosal perforation & 4(13.36%) had developed duodenal serosal injury in laparoscopic group whereas only 1(3.33%) patient in open pyloromyotomy group had nothing else except simple hemorrhage. The p value (0.051ns) was also statistically insignificant. In regard to post operative complications, 2(6.6%) patients had developed wound hematoma, 2(6.6%) had wound infection, 1(3.33 %) had developed wound dehiscence and incisional hernia respectively in Group A. But in group B there was no subject with any complication. This result was also statistically insignificant. So, the overall study results denote that, laparoscopic pyloromyotomy would not be considered as a superior procedure or as safe as that of traditional open pyloromyotomy for the beginners.

2008-01-01

Objective This study was performed to determine whether students who are trained in developing a personal formulary become more competent in rational prescribing than students who have only learned to use existing formularies. Methods This was a multicentre, randomised, controlled study conducted in eight universities in India, Indonesia, the Netherlands, the Russian Federation, Slovakia, South Africa, Spain and Yemen. Five hundred and eighty-three medical students were randomised into three groups: the personal formulary group (PF; 94), the existing formulary group (EF; 98) and the control group (C; 191). The PF group was taught how to develop and use a personal formulary, whereas e the EF group was taught how to review and use an existing formulary. The C group received no additional training and participated only in the tests. Student’s prescribing skills were measured by scoring their treatment plans for written patient cases. Results The mean PF group score increased by 23% compared with 19% for the EF group (p < 0.05) and 6% for controls (p < 0.05). The positive effect of PF training was only significant in universities that had a mainly classic curriculum. Conclusion Training in development and use of a personal formulary was particularly effective in universities with a classic curriculum and with traditional pharmacology teaching. In universities with a general problem-based curriculum, pharmacotherapy teaching can be based on either existing or personal formularies. PMID:18338161

Does theory of mind performance differ in children with early-onset and regressive autism?

PubMed

Matthews, Nicole L; Goldberg, Wendy A; Lukowski, Angela F; Osann, Kathryn; Abdullah, Maryam M; Ly, Agnes R; Thorsen, Kara; Spence, M Anne

2012-01-01

A deficit in theory of mind (ToM), or the ability to infer the mental states of others, has been implicated as one of the major characteristics of Autism Spectrum Disorder (ASD); however, little attention has been devoted to possible differences in ToM ability within ASD. The current study examined ToM performance in children with early-onset autism and regressive autism in comparison to typically developing children. Results indicated that children in the regressive autism group performed significantly better than the early-onset autism group on the non-verbal appearance-reality task. Additionally, Fisher's exact tests indicated a pattern of lowest scores in the early-onset group and highest scores in the typically developing group, whereas the regressive autism group tended to score in between the early-onset and typically developing groups. The apparent heterogeneity in ToM performance within ASD could account for the lack of universality in ToM ability found in previous studies. © 2011 Blackwell Publishing Ltd.

This study was performed to evaluate the effectiveness of 'village health worker training program' which aimed to build community participatory health promotion capacity of community leaders in villages of low developed country and to develop methods for further development of the program. The intervention group were 134 community leaders from 25 barangays (village). Control group were 149 form 4 barangays. Intervention group participated 3-day training program. Questionnaire was developed based on 'Health Promotion Capacity Checklist' which assessed capacity in 4 feathers; 'knowledge', 'skill', 'commitment', and 'resource'. Each feather was assessed in 4 point rating scale. Capacity scores between intervention group and control group were examined to identify changes between the pre- and post-intervention periods. A qualitative evaluation of the program was conducted to assess the appropriateness of the program. The program was conducted in Tuguegarao city, Philippine in January, 2009. The result showed significant increases in the total health promotion capacity and each feather of health promotion capacities between pre and post assessment of intervention group. But there was no significant change in that of control group. Participants marked high level of satisfaction for preparedness, selection of main subjects and education method. Qualitative evaluation revealed that training program facilitated community participatory health promotion capacity of participants. This study suggested that the Village health worker training program is effective for building health promotion capacity of community leaders and it can be a main method for helping low developed countries with further development.

Auditory, speech and language development in young children with cochlear implants compared with children with normal hearing.

Schramm, Bianka; Bohnert, Andrea; Keilmann, Annerose

2010-07-01

This study had two aims: (1) to document the auditory and lexical development of children who are deaf and received the first cochlear implant (CI) by the age of 16 months and the second CI by the age of 31 months and (2) to compare these children's results with those of children with normal hearing (NH). This longitudinal study included five children with NH and five with sensorineural deafness. All children of the second group were observed for 36 months after the first fitting of the device (cochlear implant). The auditory development of the CI group was documented every 3 months up to the age of two years in hearing age and chronological age and for the NH group in chronological age. The language development of each NH child was assessed at 12, 18, 24 and 36 months of chronological age. Children with CIs were examined at the same age intervals at chronological and hearing age. In both groups, children showed individual patterns of auditory and language development. The children with CIs developed differently in the amount of receptive and expressive vocabulary compared with the NH control group. Three children in the CI group needed almost 6 months to make gains in speech development that were consistent with what would be expected for their chronological age. Overall, the receptive and expressive development in all children of the implanted group increased with their hearing age. These results indicate that early identification and early implantation is advisable to give children with sensorineural hearing loss a realistic chance to develop satisfactory expressive and receptive vocabulary and also to develop stable phonological, morphological and syntactical skills for school life. On the basis of these longitudinal data, we will be able to develop new diagnostic tools that enable clinicians to assess child's progress in hearing and speech development.

The Gynecologic Cancer Study Group (GCSG) of the Japan Clinical Oncology Group (JCOG) was organized in 1994. The GCSG has developed under the leadership of three successive group representatives, five principal study investigators, the cooperation of group members and the support of several public research funds. At present, 38 institutions are participating as active members of the GCSG of the JCOG. In addition to gynecologic oncologists, medical oncologists, pathologists and radiotherapists are participating in our group. Our group manages female genital malignancies including uterine cervical, endometrial, ovarian, tubal and vulvar cancers. Because the incidences of uterine cervical (in younger women), endometrial and ovarian cancer have increased in Japan in recent years, we are developing new standard treatments especially for these malignancies. As of 31 May 2011, our group has conducted six JCOG clinical trials (three completed and three ongoing) and completed one JCOG accompanying study, which is now in preparation for publication. Our group has also conducted several retrospective studies, and Phase I and II trials independent of the JCOG Data Center. Our aim is to conduct unique and high-quality clinical trials which we can appeal to the world. In this review, we present the organization and achievements of our group, along with a list of participating institutions, as the history of the GCSG of the JCOG.

In animal studies, extensive data revealed the influence of culture medium on embryonic development, foetal growth and the behaviour of offspring. However, this impact has never been investigated in humans. For the first time, we investigated in depth the effects of embryo culture media on health, growth and development of infants conceived by In Vitro Fertilization until the age of 5 years old. This single-centre cohort study was based on an earlier randomized study. During six months, in vitro fertilization attempts (No. 371) were randomized according to two media (Single Step Medium--SSM group) or Global medium (Global group). This randomized study was stopped prematurely as significantly lower pregnancy and implantation rates were observed in the SSM group. Singletons (No. 73) conceived in the randomized study were included (42 for Global and 31 for SSM). The medical data for gestational, neonatal and early childhood periods were extracted from medical records and parental interviews (256 variables recorded). The developmental profiles of the children in eight domains (social, self-help, gross motor, fine motor, expressive language, language comprehension, letter knowledge and number knowledge--270 items) were compared in relation to the culture medium. The delivery rate was significantly lower in the SSM group than in the Global group (p<0.05). The culture medium had no significant effect on birthweight, risk of malformation (minor and major), growth and the frequency of medical concerns. However, the children of the Global group were less likely than those of the SSM group to show developmental problems (p = 0.002), irrespective of the different domains. In conclusion, our findings showed that the embryo culture medium may have an impact on further development.

This study aimed to identify the effectiveness of a newly developed group therapy, called the logo-autobiography program, in improving meaning in life and mental health in the wives of alcoholics. The program was developed in four steps: literature review, pilot program development, pilot study and detailed program structuring. The pilot program was developed by combining a modified guided autobiography program with logotherapy. A non-randomized controlled trial was conducted with a pre- and post-test design. The instruments chosen for the study were the Purpose in Life (PIL) test and the Symptom Checklist-90-Revision (SCL-90-R) to measure the meaning in life and mental health. Data were collected between November 2006 and March 2007 from 19 subjects in the experimental group and 21 subjects in the control group, who were all wives of alcoholics from four South Korean cities. The score for meaning in life was significantly higher in the experimental group than in the control group (p = .047). Also, the scores for somatization (p = .001), interpersonal sensitivity (p = .008), depression (p = .003), hostility (p = .002) and global severity index (p = .001) were significantly lower in the experimental group than in the control group. This study indicated that the logo-autobiography program enhanced both meaning in life and mental health in alcoholics' wives, which suggests that the program would be very beneficial to this population. Furthermore, it might be suitable for improving mental health in families and communities that suffer from psychological trauma and meaninglessness.

Students' development of models of magnetic materials, patterns of group activity, and social norms in a physics classroom

Johnson, Andrew P.

1999-11-01

This dissertation is a study of students' model development processes in a physical science course for preservice elementary teachers. It details the models of magnetic materials developed and used by students during a unit on static electricity and magnetism. In this inquiry-based course, the class developed and formally accepted a model, in the form of diagrams and descriptions, that is very similar to the accepted magnetic domains model. They did this without textbooks or lectures on magnetism. Before adopting this model, however, most groups in the class temporarily used models involving opposite charges at the two ends of magnetized nails. How did the students do it? The explanation involves detailed study of the groups' interactions and use of structure in the classroom environment. This dissertation uses two theoretical frameworks to analyze interactions. It applies Yackel and Cobb's (1996) concepts of classroom social norms to characterize aspects of the classroom participation structure which affected groups' construction and declaration of models. It also applies distributed cognition ideas to analyze the sense-making conversations that small groups had when constructing group responses. This research found that conversations in one small group could be characterized into sixteen categories. Important categories included "extending ideas" which involved gradual deepening and elaboration of the group's understanding of their model(s), and "joint typing", an interactive process by which group members collaborated on typed statements or group diagrams and simultaneously developed common language for communicating their ideas to each other. Some of these categories of activity were closely connected to computer use. Also, four classroom norms are described. One small group social classroom norm involved group members developing a "common ground" consisting of agreed-upon group statements. Three sociophysics norms which characterize the whole class interactions as well as those of the small group involved a distinction between generalizations of phenomena and theoretical statements, class criteria for accepting evidence, and the obligation for each group to have a model of magnetic materials that they could support with acceptable evidence.

Early auditory and speech development in home-based early intervention of infants and toddlers with hearing loss younger than 2 years are still spare in China. This study aimed to observe the development of auditory and speech in deaf infants and toddlers who were fitted with hearing aids and/or received cochlear implantation between the chronological ages of 7-24 months, and analyze the effect of chronological age and recovery time on auditory and speech development in the course of home-based early intervention. This longitudinal study included 55 hearing impaired children with severe and profound binaural deafness, who were divided into Group A (7-12 months), Group B (13-18 months) and Group C (19-24 months) based on the chronological age. Categories auditory performance (CAP) and speech intelligibility rating scale (SIR) were used to evaluate auditory and speech development at baseline and 3, 6, 9, 12, 18, and 24 months of habilitation. Descriptive statistics were used to describe demographic features and were analyzed by repeated measures analysis of variance. With 24 months of hearing intervention, 78% of the patients were able to understand common phrases and conversation without lip-reading, 96% of the patients were intelligible to a listener. In three groups, children showed the rapid growth of trend features in each period of habilitation. CAP and SIR scores have developed rapidly within 24 months after fitted auxiliary device in Group A, which performed much better auditory and speech abilities than Group B (P < 0.05) and Group C (P < 0.05). Group B achieved better results than Group C, whereas no significant differences were observed between Group B and Group C (P > 0.05). The data suggested the early hearing intervention and home-based habilitation benefit auditory and speech development. Chronological age and recovery time may be major factors for aural verbal outcomes in hearing impaired children. The development of auditory and speech in hearing impaired children may be relatively crucial in thefirst year's habilitation after fitted with the auxiliary device.

The goal of this study was to examine the relative contributions of growth deficiency and psychosocial factors to cognitive development in toddlers with infantile anorexia. Eighty-eight toddlers, ranging in age from 12 to 33 months, were enrolled in this study. Toddlers were evaluated by 2 child psychiatrists and placed into 1 of 3 groups: infantile anorexia, picky eater, and healthy eater. All 3 groups were matched for age, race, gender, and socioeconomic status (SES). Toddlers underwent nutritional evaluations and cognitive assessments with the Bayley Scales of Infant Development. Toddlers and their mothers were also videotaped during feeding and play interactions, which later were rated independently by 2 observers. On average, toddlers with infantile anorexia performed within the normal range of cognitive development. However, the Mental Developmental Index (MDI) scores of the healthy eater group (MDI = 110) were significantly higher than those of the infantile anorexia (MDI = 99) and picky eater (MDI = 96) groups. Within the infantile anorexia group, correlations between MDI scores and the toddlers' percentage of ideal body weight approached statistical significance (r =.32). Across all groups, the toddlers' MDI scores were associated with the quality of mother-child interactions, SES level, and maternal education level. Collectively, these variables explained 22% of the variance in MDI scores. This study demonstrated that psychosocial factors, such as mother-toddler interactions, maternal education level, and SES level, are related to the cognitive development of toddlers with feeding problems and explain more unique variance in MDI scores than nutritional status.

In this study, we investigated the development of clinical disease and immune responses in the development of an experimental model of flea allergy dermatitis. Dogs were randomly divided into four treatment groups and were infested with fleas on two different feeding schedules (continuous and episodic). Group 1 consisted of four non-exposed dogs (negative controls) and Group 2 consisted of six dogs exposed to fleas continually. Groups 3 and 4 consisted of 14 dogs each that were exposed to fleas on an episodic schedule (two consecutive days every other week for 12 weeks). Group 4 also received intraperitoneal injections of a low dose of lectin (ricin) with immunomodulatory properties. The purpose of Group 4 was to investigate the effects of ricin on enhancing the development of clinical signs, flea antigen-specific IgE levels and altering the number of CD4+ and CD8+ T cell subsets in peripheral blood. Clinical signs developed in all flea exposed dogs, however, the dermatology lesion scores were less and shorter in duration for continuously exposed dogs compared to episodic exposed dogs, independent of ricin treatment. Lesion development was concentrated in the flea triangle and consisted principally of erythema, followed by alopecia, excoriation, papules, and crusts. CD4+ and CD8+ lymphocyte subsets or IgE levels were not altered by ricin treatment. Flea antigen-specific IgE values were highest in dogs exposed to fleas on a continuous basis compared to those episodically exposed. A greater percentage of clinical responder dogs with negative flea-specific IgE titers or negative intradermal test (IDT) were present in the episodic exposure groups than in the continuous exposure group. IgE titers corresponded slightly better with clinical responders than the IDT. The agreement between the IgE titers and IDT was good (weighted K = 0.67). Histopathology of skin samples were consistent with a Type I hypersensitivity. In conclusion, we were able to develop a model of flea allergy dermatitis by experimentally exposing dogs to fleas on an episodic and continuous feeding schedule. In this study, continuously exposed dogs did not develop immunotolerance, and ricin did not enhance the development of FAD. Copyright 2004 Elsevier B.V.

Development of professional knowledge in action: experiences from an action science design focusing on acknowledging communication in mental health.

This article reports a multi-professional development project that was based on an action science design. The purpose was to develop 'acknowledging communication' in a psychiatric department for young people, and the objective to study the staffs' experiences of participating in the project. The professional part of the project has its foundation in Schibbye's treatment theory of inter-subjective understanding of relationships, and involves three main approaches from her theory: self-reflection, self-delimitation and emotional presence. The article presents the specific action design used, where reflection processes were developed in three different arenas: multidisciplinary Reflection groups, a Leader support group for the group leaders of the Reflection groups and collective Project seminars for all employees. A formal study programme designed to increase professional expertise, 15 European Credit Transfer System (ECTS), was also offered. The research methods included the researcher's process notes taken during the process, field notes from participating in the Leader support group, and qualitative interviews of eight informants participating in the various reflection arenas. The article presents and discusses the experiences evolved from the methods that were developed during the professional action science project: reflection on specific situations of interaction with patients in the form of oral/written narratives and the development of video presentations in combination with 'reflective teams'. The study showed that to facilitate change in the role of staff members, it is important to combine several reflection arenas where theoretical principles can be converted into practical action. By drawing data from only one study site, the study has a limited transferability, but should be of interest for professionals working with clinical change processes.

Health policies are important instruments for improving population health. However, experience suggests that policies designed for the whole population do not always benefit the most vulnerable. Participation of vulnerable groups in the policy-making process provides an opportunity for them to influence decisions related to their health, and also to exercise their rights. This paper presents the findings from a study that explored how vulnerable groups and principles of human rights are incorporated into national sexual and reproductive health (SRH) policies of 4 selected countries (Spain, Scotland, Republic of Moldova, and Ukraine). It also aimed at discussing the involvement of vulnerable groups in SRH policy development from the perspective of policy-makers. Literature review, health policy analysis and 5 semi-structured interviews with policy-makers were carried out in this study. Content analysis of SRH policies was performed using the EquiFrame analytical framework. The study revealed that vulnerable groups and core principles of human rights are differently addressed in SRH policies within 4 studied countries. The opinions of policy-makers on the importance of mentioning vulnerable groups in policy documents and the way they ought to be mentioned varied, but they agreed that a clear definition of vulnerability, practical examples, and evidences on health status of these groups have to be included. In addition, different approaches to vulnerable group's involvement in policy development were identified during the interviews and the range of obstacles to this process was discussed by respondents. Incorporation of vulnerable groups in the SRH policies and their involvement in policy development were found to be important in addressing SRH of these groups and providing an opportunity for them to advocate for equal access to healthcare and exercise their rights. Future research on this topic should include representatives of vulnerable communities which could help to build a dialogue and present the problem from multiple perspectives. © 2015 by Kerman University of Medical Sciences.

Longitudinal tracking of 107 three- to-thirteen-year-olds in a cross-sequential design showed a 6-step theory of mind (ToM) sequence identified by a few past cross-sectional studies validly depicted longitudinal ToM development from early to middle childhood for typically developing (TD) children and those with ToM delays owing to deafness or autism. Substantively, all groups showed ToM progress throughout middle childhood. Atypical development was more extended and began and ended at lower levels than for TD children. Yet most children in all groups progressed over the study's mean 1.5 years. Findings help resolve theoretical debates about ToM development for children with and without delay and gain strength and weight via their applicability to three disparate groups varying in ToM timing and sequencing. © 2018 Society for Research in Child Development.

The possibility of association between ABO blood groups and malignancy was first discussed by Anderson DE & Haas C. The association between blood group and oral cancer is least explored and hence this study was undertaken to evaluate relationship of ABO blood groups with an increased risk for oral cancer. The present study was conducted at various cancer hospitals in Kanpur. The study samples comprised 100 oral cancer patients and 50 controls with tobacco chewing habit. The information regarding the socio demographic profile, history on tobacco habits, type of oral cancer and ABO blood group profile was obtained from the case sheets of the patients. The frequency of squamous cell carcinoma was significantly higher in men (78%) than women (22%) and mostly found in the age range of 45-65 years and also consuming chewing type of tobacco. It was found that out of 100 patients, 53 were of blood group B+ve, 28 of O +ve, 16 of A+ve and 3 had the blood group AB+ve. The high potential risk of developing OSCC was more in B+ve blood group (1.96 times), and relative frequency (%) in blood group O+ve (1.64 times) than in the control group Among locations of oral cancers, squamous cell carcinoma of tongue (25%) and buccal mucosa (15%) was more common in B+ve and Carcinoma of floor of mouth (11%) was more common in O+ve blood group cases. It was found that people with blood group B+ve, followed by O+ve had increased risk of developing OSCC with most prevalent being Well Differentiated OSCC as compared to people of other blood groups. The present study reveals that there is an inherited element in the susceptibility against different types of oral cancers. The people with blood group B+ve and O+ve having tobacco chewing habits can be appraised that they are more at risk to develop oral cancer than people with other blood groups.

The purpose of this study was to evaluate and compare, clinically and radiographically, the effects of platelet-rich fibrin (PRF) and mineral trioxide aggregate (MTA) as pulpotomy agents in permanent teeth with incomplete root development. A total number of 70 children requiring pulpotomy in 70 permanent molars with incomplete root development were screened. Sixty-two patients met the inclusion criteria and were enrolled in the study. The patients were randomly allocated equally in 2 treatment groups. MTA pulpotomy was performed in group A (the control group), and PRF pulpotomy was performed in group B (the experimental group). The treated teeth were restored with amalgam followed by stainless steel crowns. Clinical and radiographic evaluations were performed after 6, 12, and 24 months. Thus, the data obtained were blindly analyzed using the chi-square test. There was no significant difference between the 2 groups in terms of clinical and radiologic success. Radiographically, all available cases (53 teeth) showed evidence of root growth and canal narrowing. Complete apical closure was observed in 88.8% in the PRF group (experimental group) and 80.07% of roots in the MTA group (control group), respectively, at 24 months. PRF could be used as a suitable biological and economic alternative to MTA in pulpotomy procedures of permanent teeth with incomplete root development.

Certain factors in mothers could be risk indicators for certain diseases in their children. Hence, this study was undertaken to assess maternal risk indicators for the development of early childhood caries in their children. A comparative, cross-sectional study was designed among 180 mother-child pairs attending various Anganwadi centers. Demographic, dietary, oral hygiene practices and other necessary information were collected from mothers using a structured questionnaire. Caries status and amount of plaque were recorded through clinical examination. Nonstimulated saliva from mothers was cultured for mutans streptococci (MS). Data were analyzed using SPSS version 17. Chi-square, Student's t-test, and logistic regression were used. A P ≤ 0.05 was considered statistically significant. In the study group, 73.3% of mothers had caries as compared to only 53.3% mothers in control group. While mean DMFT and mean DMFS of mothers in the study group was 3.78 ± 3.91 and 8.37 ± 12.2, respectively, the same for the mothers in the control group was 2.66 ± 3.01 and 5.8 ± 5.3. Sixty (66.7%) out of ninety mothers in the study group had a high MS count as compared to only 40 (44.4%) mothers in control group (P = 0.003). The present study showed that high salivary MS count and decay in mothers could be important risk indicators for the development of caries in their children.

The role of awareness of repetition during the development of automaticity in a dot-counting task

PubMed Central

Shadbolt, Emma

2018-01-01

This study examined whether being aware of the repetition of stimuli in a simple numerosity task could aid the development of automaticity. The numerosity task used in this study was a simple counting task. Thirty-four participants were divided into two groups. One group was instructed that the stimuli would repeat many times throughout the experiment. The results showed no significant differences in the way automatic processing developed between the groups. Similarly, there was no correlation between the point at which automatic processing developed and the point at which participants felt they benefitted from the repetition of stimuli. These results suggest that extra-trial features of a task may have no effect on the development of automaticity, a finding consistent with the instance theory of automatisation. PMID:29404220

Participants ( n = 36) with consistent Pre-conformist ego development levels during multiple adolescent assessments were studied to determine whether and how their ego levels had changed at age 25. Those ( n = 12) whose ego levels remained at the Pre-conformist level were assigned to a life-course-persistent profound ego development arrest trajectory group; those ( n = 24) whose ego levels reached the Conformist or Post-conformist level at age 25 were assigned to an adolescence-limited profound ego development arrest trajectory group. Analysis of predictors and age 25 correlates of group membership revealed that selected age 14 family interaction behaviors differentiated the two groups. At age 25, members of the adolescence-limited group showed superior performance on several measures of interpersonal and intrapersonal functioning.

Oral cancer is one of the most common cancers in the world. Although multifactorial, the exact pathogenesis of oral cancer is still unclear. Apart from tobacco chewing and smoking, chronic long-term irritation by ill-fitting denture is also said to be an important risk factor for the development of oral cancer. Literature quotes some amount of evidence that correlates long-term denture irritation as a risk factor for the development of oral cancer. Hence, we analyzed the correlation of denture-related sores as a risk factor for the development of oral cancer. The present case-control study included 140 newly diagnosed oral cancer cases and 140 patients as the control healthy group. One-hour questionnaire was framed and was conducted to the control group and the study group by 10 experienced interviewers who were trained for such type of analysis. Assessment of the patients' socioeconomic status, cigarette smoking habit, alcohol drinking habit, and oral health status was done and compared on the two study groups. Logistic regression models along with multivariate models were used for the assessment of the results. In the control group and the cancer patient group, total of 140 new cancer cases and 140 subjects were included. Out of 140 patients in the cancer group, 16 were nonsmokers, while 110 smoked cigarette in the cancer patient group. As far as alcohol consumption is concerned, 42 patients in the control group and 102 patients in the oral cancer group were chronic heavy drinkers. Fried food intake was high in both the groups. Significant correlation was obtained while comparing the heavy smokers, heavy alcohol consumers, and oral health status in both the study groups. Our results favor the hypothesis that positive correlation exists between oral cancer risk and recurrent denture sores. People wearing denture prosthesis should be periodically visualized for identification of any mucosal alteration or changes at the earliest.

Alberta Infant Motor Scale (AIMS) scores were examined before and after four months of swimming classes in 12 babies (ages 7 to 9 mo.) assigned to Experimental (n = 6) and Control (n = 6) groups matched on age and developmental status. Infants from both groups improved their developmental status from pre- to post-test; the Experimental group improved on mean percentile rank. The sample size and the discriminative power of the AIMS do not allow conclusive judgments on these group differences, hence on the effect of infant swimming classes. Nevertheless, a number of recommendations are made for future studies on the effect of swimming classes on infant motor development.

Background: Home visit program can be effective in infants’ growth and development. The present study aimed to investigate the effect of home visit program on preterm infants’ growth and development within 6 months. Methods: It was a double-blind clinical trial study. The study was conducted in Hafez, Hazrat-e-Zeinab, and Namazee Hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran from 2010 to 2011. Preterm infants were divided into intervention (n=30) and control groups (n=30) through blocked randomization. The intervention group received home visit training program for 6 months, while the control group only received the hospital’s routine care. Then, the infants’ growth indexes, including weight, height, and head circumference, and development criteria were compared on the first day of admission in Neonatal Intensive Care Unit, and then first, second, third, and sixth months. The data were analyzed using Chi-square, independent t-test, and repeated measures ANCOVA. Results: The mean weight of the intervention and control group infants was 7207.3±1129.74 and 6366.7±922.26 gr in the sixth month. Besides, the intervention group infants’ mean weight was higher compared to the control group after six months (t=-3.05, P=0.03). Also, a significant difference was found between the two groups regarding development indexes, such as following moving objects with the head, keeping the head stable when changing the position from lying to sitting,  producing “Agha” sound, and taking objects by hand (P<0.05) during six months of age. Conclusion: The results showed that the home visit program was effective in preterm infants’ weight gain and some development indexes at the sixth month. Considering the importance of infants’ growth and development, healthcare staff is recommended to incorporate home visit training into their programs, so that steps can be taken towards improvement of preterm infants’ health.

Home visit program can be effective in infants' growth and development. The present study aimed to investigate the effect of home visit program on preterm infants' growth and development within 6 months. It was a double-blind clinical trial study. The study was conducted in Hafez, Hazrat-e-Zeinab, and Namazee Hospitals affiliated to Shiraz University of Medical Sciences, Shiraz, Iran from 2010 to 2011. Preterm infants were divided into intervention (n=30) and control groups (n=30) through blocked randomization. The intervention group received home visit training program for 6 months, while the control group only received the hospital's routine care. Then, the infants' growth indexes, including weight, height, and head circumference, and development criteria were compared on the first day of admission in Neonatal Intensive Care Unit, and then first, second, third, and sixth months. The data were analyzed using Chi-square, independent t-test, and repeated measures ANCOVA. The mean weight of the intervention and control group infants was 7207.3±1129.74 and 6366.7±922.26 gr in the sixth month. Besides, the intervention group infants' mean weight was higher compared to the control group after six months (t=-3.05, P=0.03). Also, a significant difference was found between the two groups regarding development indexes, such as following moving objects with the head, keeping the head stable when changing the position from lying to sitting,  producing "Agha" sound, and taking objects by hand (P<0.05) during six months of age.

Brown, Louis D; Tang, Xiaohui; Hollman, Ruth L

2014-03-01

Self-help support groups are indigenous community resources designed to help people manage a variety of personal challenges, from alcohol abuse to xeroderma pigmentosum. The social exchanges that occur during group meetings are central to understanding how people benefit from participation. This paper examines the different types of social exchange behaviors that occur during meetings, using two studies to develop empirically distinct scales that reliably measure theoretically important types of exchange. Resource theory informed the initial measurement development efforts. Exploratory factor analyses from the first study led to revisions in the factor structure of the social exchange scales. The revised measure captured the exchange of emotional support, experiential information, humor, unwanted behaviors, and exchanges outside meetings. Confirmatory factor analyses from a follow-up study with a different sample of self-help support groups provided good model fit, suggesting the revised structure accurately represented the data. Further, the scales demonstrated good convergent and discriminant validity with related constructs. Future research can use the scales to identify aspects of social exchange that are most important in improving health outcomes among self-help support group participants. Groups can use the scales in practice to celebrate strengths and address weaknesses in their social exchange dynamics.

A controlled, blind research study was conducted to define the initial inflammatory response and lung damage associated with the death of immature adult Dirofilaria immitis in cats as compared with cats developing adult heartworm infections and cats on preventive medication. Three groups of cats were utilized, 10 per group. All cats were infected with 100 third-stage (L3) larvae by subcutaneous injection. Group A cats were treated topically with selamectin (Revolution®; Zoetis) per label directions at 28 days post infection (PI) and once monthly for 8 months. Group B cats were treated orally with ivermectin (Ivomec®; Merial) at 150 μg/kg at 70 days PI, then every 2 weeks for 5 months. Group C cats were untreated PI. At baseline (Day 0) and on Days 70, 110, 168, and 240 PI, peripheral blood, serum, bronchial lavage, and thoracic radiographic images were collected on all cats. Upon completion of the study (Day 245), cats were euthanized and necropsies were conducted. Results were analyzed statistically between groups by ANOVA and by paired sample T testing for changes within the group over time. The selamectin-treated cats (Group A) did not develop radiographically evident changes throughout the study and were free of adult heartworms or worm fragments at necropsy. The heartworm life cycle was abbreviated with oral doses of ivermectin (Group B), shown by the absence of adult heartworms or worm fragments at necropsy. The early stage of immature adult worm in Group B cats, however, did induce severe pulmonary airway, interstitial, and arterial lung lesions, revealing that the abbreviated infection is a significant cause of respiratory pathology in cats. Cats in Groups B and C could not be differentiated based on radiographic changes, serologic antibody titers, complete blood count, or bronchoalveolar lavage cytology at any time point throughout the study. Eighty percent of cats in Group A and 100% of cats in Groups B and C became heartworm antibody positive at some time point post infection. The clinical implications of this study are that cats that become infected with immature adult heartworms may not develop fully mature heartworms and are only transiently heartworm antibody positive, but do develop Heartworm-Associated Respiratory Disease (HARD).

The aim of this study was to specify the causes of occupational accidents, determine social responsibility and the role of groups involved in work-related accidents. This study develops occupational accidents causes tree, occupational accidents responsibility tree, and occupational accidents component-responsibility analysis worksheet; based on these methods, it develops cause-responsibility analysis (CRA) techniques, and for testing them, analyzes 100 fatal/disabling occupational accidents in the construction setting that were randomly selected from all the work-related accidents in Tehran, Iran, over a 5-year period (2010-2014). The main result of this study involves two techniques for CRA: occupational accidents tree analysis (OATA) and occupational accidents components analysis (OACA), used in parallel for determination of responsible groups and responsibilities rate. From the results, we find that the management group of construction projects has 74.65% responsibility of work-related accidents. The developed techniques are purposeful for occupational accidents investigation/analysis, especially for the determination of detailed list of tasks, responsibilities, and their rates. Therefore, it is useful for preventing work-related accidents by focusing on the responsible group's duties. Copyright © 2016 Elsevier Ltd. All rights reserved.

recurrent wheezing is a common problem during the first years of life, but it is still difficult to identify which of these children may develop asthma in the future. To study risk factors of developing asthma in a group of patients with frequent wheezing during the first three years of life. A prospective study was performed of a group of 60 patients, aged below three, referred to our Hospital for recurrent wheezing. Age, sex, parental and personal history of atopy, clinical features, laboratory tests, evolution and response to treatment were analyzed. 60 patients were enrolled in study. Most of children were boys and have had the first episode of wheezing after the 6 months of life. 63 % had personal history of atopy and 55 % parental history of allergy. The group of atopic children had more wheezing exacerbations and worse evolution than the group of non atopic. They also had more treatment necessities. The identification of young children at high risk of developing asthma could permit an early intervention before irreversible changes in the airway appeared.

The purpose of this study was to investigate whether the levels of total antioxidant capacity (TAC), total peroxide and oxidative stress index (OSI) are associated with the development of collaterals in total coronary occlusions. Our study group contained 176 consecutive men patients with single-vessel TCO, 94 of whom had poorly developed coronary collateral, while 82 had well-developed coronary collateral. TAC and total peroxide concentration were measured of plasma. The ratio of TAC to total peroxide was accepted as an indicator of oxidative stress. The values of total peroxide and OSI in the Group I were significantly lower than that in Group II (p<0.001, for both). TAC levels were significantly higher in patients with poorly developed collaterals than in well-developed collateral group (p<0.001). OSI values were also significantly different among the Rentrop class-0, -1, -2 and -3 (ANOVA p<0.001). We found significant correlations between collaterals score and TAC, total peroxide and OSI levels (p<0.001 for all). In multiple linear regression analysis, total peroxide and OSI were independent predictors of collaterals score (p=0.006 and p<0.001 respectively). This study clearly demonstrates that the level of OSI is independently and positively associated with the presence of collateral circulation in total coronary occlusion patients.

2017-01-01

Abstract Social groups aid human beings in several ways, ranging from the fulfillment of complex social and personal needs to the promotion of survival. Despite the importance of group affiliation to humans, there remains considerable variation in group preferences across development. In the current study, children and adolescents completed an explicit evaluation task of in-group and out-group members during functional neuroimaging. We found that participants displayed age-related increases in bilateral amygdala, fusiform gyrus and orbitofrontal cortex (OFC) activation when viewing in-group relative to out-group faces. Moreover, we found an indirect effect of age on in-group favoritism via brain activation in the amygdala, fusiform and OFC. Finally, with age, youth showed greater functional coupling between the amygdala and several neural regions when viewing in-group relative to out-group peers, suggesting a role of the amygdala in directing attention to motivationally relevant cues. Our findings suggest that the motivational significance and processing of group membership undergoes important changes across development. PMID:27633395

Background The aims of this study were to investigate the relationship between optimal anthropometric indices and their cut-off values and the incidence of hypertension in a cohort of middle-aged women in China. Material/Methods A cohort of 812 women, aged between 40–70 years were recruited between May 2011 and June 2013. An ideal baseline blood pressure was defined as <120/80 mmHg; pre-hypertension was 120–139/80–89 mmHg; hypertension was ≥140/≥90 mmHg. Anthropometric measurements included waist circumference (WC), body mass index (BMI), waist-hip ratio (WHR), and waist-height ratio (WHtR). The cohort was divided into an ideal blood pressure group (Group 1) and a pre-hypertensive group (Group 2). Two-year follow-up blood pressure measurements were performed. Receiver-operating characteristic (ROC) curve analysis determined the optimal anthropometric indices and cut-off values for developing hypertension. Results At two-year follow-up, hypertension developed in 9.0% (n=31) in Group 1 and 32.3% (n=121) in Group 2. Logistic regression analysis showed that in both groups, women in the highest quartile for WC, BMI, WHR, and WHtR had a significantly increased risk of developing hypertension compared with the lowest quartile (P<0.05). ROC curve area under the curve (AUC) for these anthropometric indices were greater in Group 1, and for WC in Groups 1 and 2, with the optimal cut-off values greater in Group 1. Conclusions In a cohort of middle-aged women in China, anthropometric indices of obesity were predictive of the development of hypertension during a two-year follow-up period. PMID:29601569

We aimed to show the relationship between paraoxonase 1 (PON1) gene polymorphism and the development of prostate cancer (PCa). We investigated the association of single nuclotide polymorphisms of PON1 enzyme with the development of PCa risk. A total of 147 male patients were divided into PCa, and control groups. The control group was also divided into two subgroups according to serum prostate specific antigen (PSA) levels as non PCa-high PSA (>4 ng/mL) and non PCa-low PSA (≤4 ng/mL) groups. The mean ages of the patients were 64.81 years, 63.27 years and 64.22 years in PCa group, non PCa-low PSA and non PCa -high PSA groups, respectively. The mean PSA levels were 10.9 ng/mL, 1.16 ng/mL and 6.63 ng/mL for PCa group, non PCa -low PSA and non PCa -high PSA groups, respectively. In terms of PON1 polymorphisms and allele frequencies, there were no statistically significant differences between PCa and control groups. There was not a statistically significant difference between PCa and non PCa-high PSA groups as for genotypic and allelic frequencies. As a result of this small sample sized hypothetical study of polymorphism, a relationship could not be detected between PCa development and PON1 gene polymorphism. According to the results of this preliminary study, it is thought that more comprehensive future studies are necessary to clarify the possible role of PON1 gene polymorphism in the etiology of PCa.

Background: Two main factors determine the strength of tendon repair; the tensile strength of material and the gripping capacity of a suture configuration. Different repair techniques and suture materials were developed to increase the strength of repairs but none of techniques and suture materials seem to provide enough tensile strength with safety margins for early active mobilization. In order to overcome this problem tendon suturing implants are being developed. We designed two different suturing implants. The aim of this study was to measure tendon-holding capacities of these implants biomechanically and to compare them with frequently used suture techniques Materials and Methods: In this study we used 64 sheep flexor digitorum profundus tendons. Four study groups were formed and each group had 16 tendons. We applied model 1 and model 2 implant to the first 2 groups and Bunnell and locking-loop techniques to the 3rd and 4th groups respectively by using 5 Ticron sutures. Results: In 13 tendons in group 1 and 15 tendons in group 2 and in all tendons in group 3 and 4, implants and sutures pulled out of the tendon in longitudinal axis at the point of maximum load. The mean tensile strengths were the largest in group 1 and smallest in group 3. Conclusion: In conclusion, the new stainless steel tendon suturing implants applied from outside the tendons using steel wires enable a biomechanically stronger repair with less tendon trauma when compared to previously developed tendon repair implants and the traditional suturing techniques.

The identification of epidemiological factors increasing the risk of endometriosis could shorten the time to diagnosis. Specific blood groups may be more common in patients with endometriosis. We designed a cross-sectional study of 633 Caucasian women living in the same geographic area. Study group included 311 patients with histologically proven endometriosis. Control group included 322 patients without endometriosis as checked during surgery. Frequencies of ABO and Rhesus groups in the study and control groups were compared using univariate and multivariate analyses. We observed a higher proportion of Rh-negative women in the study group, as compared to healthy controls. Multivariate analysis showed that Rh-negative women are twice as likely to develop endometriosis (aOR = 1.90; 95% CI: 1.20-2.90). There was no significant difference in ABO group distribution between patients and controls. There was no difference when taking into account either the clinical forms (superficial endometriosis, endometrioma, and deep infiltration endometriosis) or the rAFS stages. Rh-negative women are twice as likely to develop endometriosis. Chromosome 1p, which contains the genes coding for the Rhesus, could also harbor endometriosis susceptibility genes.

The purpose of this study was to verify effects of the Empowering A Self-Efficacy (EASE) program on self-efficacy, self-management, and child attitude toward illness in children with epilepsy. This was a quasi-experimental study with a non-equivalent control group pre-post test design. Participants were 10 to 15 year old children with epilepsy (11 in the experimental group and 10 in the control group) who were registered at one hospital in S city. The experimental group received the EASE program for 3 weeks. In the first week, a group meeting lasting 570 minutes was conducted on a single day. Over the next two weeks, telephone counselling was conducted twice a week. Data were analyzed using SPSS 18.0. There was a significant difference of pre-post evaluation of the epilepsy self-management scores in the experimental group. However, differences between the experimental group and the control group for seizure self-efficacy and child attitude toward illness were not significant. This is the first study in Korea to develop and evaluate an intervention program for children with epilepsy. Further studies are needed to confirm the effects of the EASE program.

Professional attitudes to patient participation groups: an exploratory study

1980-01-01

An exploratory study of the development of patient participation groups in general practice and general practitioners' attitudes towards them suggests that many general practitioners may not yet be aware of this innovation and may at first react negatively to the idea. This response stems in part from misconceptions about the origins and functions of these groups, a failure to see their relevance to professional objectives, and a fear that they will threaten general practitioners' autonomy and status. In contrast, general practitioners who have formed groups believe they have an important contribution to make to their developing role and have been encouraged by their experience so far. Therefore, at present, patient participation groups should neither be rejected out of hand, nor welcomed as a panacea. PMID:7452590

2015-09-01

This study conducted a needs assessment for developing teaching competencies of medical educators by assessing their perceived ability to perform teaching competencies as well as their perceived importance of these competencies. Additionally, this study examined whether there were any differences in needs assessments scores among three faculty groups. Hundred and eighteen professors from Dong-A University College of Medicine were surveyed, and the data from 44 professors who answered all the questions were analyzed using IBM SPSS 21. The needs assessment tool measured participants' perceived ability to perform teaching competencies and perceived importance of these competencies. The Borich formula was used to calculate needs assessment scores. The most urgent needs for faculty development were identified for the teaching competencies of "diagnosis and reflection," followed by "test and feedback," and "facilitation." Additionally, two, out of 51, items with the highest needs assessment scores were "developing a thorough course syllabus" and "introducing students to the course syllabus on the first day of class." The assistant professor group scored significantly higher on educational needs related to "facilitation," "affection and concern for students," and "respect for diversity" competencies than the professor group. Furthermore, the educational needs scores for all the teaching competencies except "diagnosis and reflection," "global mindset," and "instructional management" were higher for the assistant professor group than the other two faculty groups. Thus, the educational needs assessment scores obtained in this study can be used as criteria for designing and developing faculty development programs for medical educators.

Health adaptation policy for climate vulnerable groups: a 'critical computational linguistics' analysis.

Seidel, Bastian M; Bell, Erica

2014-11-28

Many countries are developing or reviewing national adaptation policy for climate change but the extent to which these meet the health needs of vulnerable groups has not been assessed. This study examines the adequacy of such policies for nine known climate-vulnerable groups: people with mental health conditions, Aboriginal people, culturally and linguistically diverse groups, aged people, people with disabilities, rural communities, children, women, and socioeconomically disadvantaged people. The study analyses an exhaustive sample of national adaptation policy documents from Annex 1 ('developed') countries of the United Nations Framework Convention on Climate Change: 20 documents from 12 countries. A 'critical computational linguistics' method was used involving novel software-driven quantitative mapping and traditional critical discourse analysis. The study finds that references to vulnerable groups are relatively little present or non-existent, as well as poorly connected to language about practical strategies and socio-economic contexts, both also little present. The conclusions offer strategies for developing policy that is better informed by a 'social determinants of health' definition of climate vulnerability, consistent with best practice in the literature and global policy prescriptions.

The purpose of this study was to develop and implement the Hospice Smart Patient Program and to evaluate its effectiveness. It was quasi-experimental non-equivalent pre-post study. Breast cancer patients who underwent surgery, chemotherapy or radiotherapy, or who needed palliative care, participated in the study. Participants were divided into two groups, experimental and control groups based on their preferences. The program was developed after literature review and discussion among experts on hospice and palliative care. Participants who were in the experimental group received either face-to-face or phone "Hospice Smart Patient" Service at least once a week for 5 months. There was a significant difference in quality of life and communication skill between the two groups after the service was provided. In addition, participants in experimental group showed improved decision making skills, mastery sense, and understanding of hospice and palliative care, which would be beneficial in improving their quality of life. We have concluded that the "Hospice Smart Patient" Program is useful for cancer patients in decision making, improving self-control and choosing hospice care to improve their quality of life.

The present study was aimed at determining the role warm saline rinse in the prevention of alveolar osteitis following dental extractions. Apparently patients aged 16 and above who were referred to the Oral Surgery Clinic of our institution, with an indication for non-surgical extraction of pathologic teeth were prospectively and uniformly randomized into warm saline group and control. The experimental group (n = 80) were instructed to gargle 6 times daily with warm saline and no such instructions were given to the second group (n = 80) to serve as controls. Information on demographic, indications for extraction, and development of alveolar osteitis were obtained and analyzed. Comparative statistics were done using Pearson's chi square or Fisher's exact test as appropriate. A p value of less than 0.05 was considered significant. The demographic and other baseline parameters such as indications for extractions were comparable among the study groups (p > 0.05). The overall prevalence of alveolar osteitis was 13.7%. There was a statistical significant difference between the study groups with respect to development of alveolar osteitis (X2 = 15.00, df = 1, p = 0.001).The risk of development of alveolar osteitis was 4 times higher in the control group (OR = 4.33, P = 0.001). Warm saline mouth rinse instruction is beneficial in the prevention of development of alveolar osteitis after dental extractions.

What happens if we compare chopsticks with forks? The impact of making inappropriate comparisons in cross-cultural research.

PubMed

Chen, Fang Fang

2008-11-01

It is a common practice to export instruments developed in one culture to another. Little is known about the consequences of making inappropriate comparisons in cross-cultural research. Several studies were conducted to fill in this gap. Study 1 examined the impact of lacking factor loading invariance on regression slope comparisons. When factor loadings of a predictor are higher in the reference group (e.g., United States), for which the scale was developed, than in the focal group (e.g., China), into which the scale was imported, the predictive relationship (e.g., self-esteem predicting life satisfaction) is artificially stronger in the reference group but weaker in the focal group, creating a bogus interaction effect of predictor by group (e.g., self-esteem by culture); the opposite pattern is found when the reference group has higher loadings in an outcome variable. Studies 2 and 3 examined the impact of lacking loading and intercept (i.e., point of origin) invariance on factor means, respectively. When the reference group has higher loadings or intercepts, the mean is overestimated in that group but underestimated in the focal group, resulting in a pseudo group difference.

Economic growth in developing countries and globalization of the food sector is leading to increasingly similar food consumption patterns worldwide. The aim of this study was to describe similarities and differences in the contributions of main food groups to energy and nutrient intakes in five developed countries across three continents. We obtained summary reports of national food consumption survey data from Australia, France, Denmark, the Netherlands, and the United States. Survey years spanned 2003-2012; sample size ranged from 1444 to 17,386. To mitigate heterogeneity of food groups across countries, we recategorized each survey's reported food groups and subgroups into eight main food groups and, for three countries, a ninth "mixed dishes" group. We determined the percent contribution of each food group to mean daily intakes of energy, saturated fat, sodium, fiber, and ten vitamins and minerals that are commonly under-consumed. Differences in findings from surveys utilizing a foods-as-consumed versus a disaggregated or ingredients approach to food group composition and contributions from the milk and milk products group, a source of several under-consumed nutrients, were explored. Patterns of food group contributions to energy and nutrient intakes were generally similar across countries. Some differences were attributable to the analytical approach used by the surveys. For the meat/protein, milk and milk products, vegetables, and fruit groups, percent contributions to key nutrient intakes exceeded percent contributions to energy intake. The mixed dishes group provided 10%-20% of total daily energy and a similar 10%-25% of the daily intake of several nutrients. This descriptive study contributes to an understanding of food group consumption patterns in developed countries.

National facilities study. Volume 3: Mission and requirements model report

NASA Technical Reports Server (NTRS)

1994-01-01

The National Facility Study (NFS) was initiated in 1992 by Daniel S. Goldin, Administrator of NASA as an initiative to develop a comprehensive and integrated long-term plan for future facilities. The resulting, multi-agency NFS consisted of three Task Groups: Aeronautics, Space Operations, and Space Research and Development (R&D) Task Groups. A fourth group, the Engineering and Cost Analysis Task Group, was subsequently added to provide cross-cutting functions, such as assuring consistency in developing an inventory of space facilities. Space facilities decisions require an assessment of current and future needs. Therefore, the two task groups dealing with space developed a consistent model of future space mission programs, operations and R&D. The model is a middle ground baseline constructed for NFS analytical purposes with excursions to cover potential space program strategies. The model includes three major sectors: DOD, civilian government, and commercial space. The model spans the next 30 years because of the long lead times associated with facilities development and usage. This document, Volume 3 of the final NFS report, is organized along the following lines: Executive Summary -- provides a summary view of the 30-year mission forecast and requirements baseline, an overview of excursions from that baseline that were studied, and organization of the report; Introduction -- provides discussions of the methodology used in this analysis; Baseline Model -- provides the mission and requirements model baseline developed for Space Operations and Space R&D analyses; Excursions from the baseline -- reviews the details of variations or 'excursions' that were developed to test the future program projections captured in the baseline; and a Glossary of Acronyms.

Group-Based Active Learning of Classification Models.

PubMed

Luo, Zhipeng; Hauskrecht, Milos

2017-05-01

Learning of classification models from real-world data often requires additional human expert effort to annotate the data. However, this process can be rather costly and finding ways of reducing the human annotation effort is critical for this task. The objective of this paper is to develop and study new ways of providing human feedback for efficient learning of classification models by labeling groups of examples. Briefly, unlike traditional active learning methods that seek feedback on individual examples, we develop a new group-based active learning framework that solicits label information on groups of multiple examples. In order to describe groups in a user-friendly way, conjunctive patterns are used to compactly represent groups. Our empirical study on 12 UCI data sets demonstrates the advantages and superiority of our approach over both classic instance-based active learning work, as well as existing group-based active-learning methods.

Background Bullying is a critical public health problem and a screening tool for use in healthcare is needed. Focus groups are a common tool for generating qualitative data when developing an instrument and evidence suggests that technology-enhanced focus groups can be effective in simultaneously engaging participants from diverse settings. Aim To examine the use of technology-enhanced focus groups in generating an item pool to develop a youth-bullying screening tool. Discussion The authors explore methodological and ethical issues related to conducting technology-enhanced focus groups, drawing on their experience in developing a youth-bullying measure. They conducted qualitative focus groups with professionals from the front lines of bullying response and intervention. They describe the experience of conducting technology-enhanced focus group sessions, focusing on the methodological and ethical issues that researchers engaging in similar work may encounter. Challenges associated with this methodology include establishing rapport among participants, privacy concerns and limited non-verbal communication. Conclusion The use of technology-enhanced focus groups can be valuable in obtaining rich data from a wide variety of disciplines and contexts. Organising these focus groups was inexpensive and preferred by the study's participants. Implications for practice Researchers should consider using technology-enhanced focus groups to generate data to develop health-related measurement tools.

Amadó, Anna; Serrat, Elisabet; Vallès-Majoral, Eduard

2016-01-01

Many studies show a link between social cognition, a set of cognitive and emotional abilities applied to social situations, and executive functions in typical developing children. Children with Down syndrome (DS) show deficits both in social cognition and in some subcomponents of executive functions. However this link has barely been studied in this population. The aim of this study is to investigate the links between social cognition and executive functions among children with DS. We administered a battery of social cognition and executive function tasks (six theory of mind tasks, a test of emotion comprehension, and three executive function tasks) to a group of 30 participants with DS between 4 and 12 years of age. The same tasks were administered to a chronological-age control group and to a control group with the same linguistic development level. Results showed that apart from deficits in social cognition and executive function abilities, children with DS displayed a slight improvement with increasing chronological age and language development in those abilities. Correlational analysis suggested that working memory was the only component that remained constant in the relation patterns of the three groups of participants, being the relation patterns similar among participants with DS and the language development control group. A multiple linear regression showed that working memory explained above 50% of the variability of social cognition in DS participants and in language development control group, whereas in the chronological-age control group this component only explained 31% of the variability. These findings, and specifically the link between working memory and social cognition, are discussed on the basis of their theoretical and practical implications for children with DS. We discuss the possibility to use a working memory training to improve social cognition in this population. PMID:27679588

In 2003 foster youth employed by a foster youth advocacy organization suggested that an evaluation of group home services to foster youth be conducted in Alameda County, California. This report presents the development and conduct of this evaluation study; how funding was obtained; and how foster youth were hired, trained, and employed to produce a timely and informative evaluation of the performance of 32 group homes where some of the foster youth formerly resided. The results of the study are described in another paper. This report contributes to evaluation practice in the newly emerging field of youth-led evaluations. The achievements of this project in utilizing group home clients to evaluate services with which they were familiar may stimulate other evaluators to develop similar projects, thereby enriching the development of our youth and promoting more informative evaluation findings.

To investigate whether congenital muscular torticollis (CMT) or the time in a prone position as an infant had any influence on motor development at preschool age. A case-control study. Eighty-one children who had participated in a previous study that investigated motor development in infants with CMT and a control group of infants without CMT. A follow-up at the age of 3.5-5 years; the Movement Assessment Battery for Children was used with the earlier CMT group and the control group to assess their motor development. An independent physiotherapist, who was blinded of the children's previous group belonging, assessed the children. Percentile scores of motor development. Multiple regression showed no impact on earlier group belonging or the amount of time spent in a prone position as an infant. The left-handed children had a significantly (P < .01) lower percentile in the Movement Assessment Battery for Children. Neither CMT nor spending limited periods of time as an infant in the prone position when awake have any significant long-term effects on motor development. Children who had CMT as infants were not at higher risk for a delay in motor development at preschool age. Copyright © 2013 American Academy of Physical Medicine and Rehabilitation.

Allner, Matthew; Bishop, Sheryl; Gushin, Vadim; McKay, Chris; Rygalov, Vadim; Allner, Matthew

Introduction: Psychosocial group functioning has become an increased international focus of many space faring nations due to the recent shift in focus of colonizing the Moon and then preparing to travel to Mars and beyond. Purpose: This study investigates the effects of pre-mission communication and awareness strategies for positive group functioning in extreme environments as well as suggestive countermeasures to maintain positive group dynamic development in isolated and confined extreme (ICE) environments. The study is supported by both preand intra-mission management efforts, which included crewmember assessments at various mission phases (pre-, intra-, and end-mission). Methods: A six person heterogeneous American crew conducted a Mars simulation mission at the Mars Society's Mars Desert Research Station in Utah, USA in 2006 as part of a new NASA training program called Spaceward Bound. Participants were administered assessments of personality, personal and group identity/functioning, subjective stress, coping, and subjective motivation. All participants were also provided information (pre-mission) regarding past research and tendencies of group functioning, stressors, cognitive functioning, and mission mistakes from a mission phase analysis approach, to see if this would be a factor in positive group dynamic development. Results: Data collected and obtained by both assessment and journaling methods were both consistent and indicative of positive personalities desirable of expedition crews. Assessment data further indicated positive group cohesion and group interactions, along with supportive and strong leadership, all which led to positive personal and group experiences for crewmembers. Crewmembers all displayed low levels of competition while still reporting high motivation and satisfaction for the group dynamic development and the mission objectives that were completed. Journals kept by the crew psychologist indicated that crewmembers all felt that the pre-mission awareness of group dynamic development tendencies of past expedition crews was integral in maintaining crew cohesiveness throughout the mission. Crewmembers felt that raising the level of awareness, both preand intra-mission, served as a positive factor in the overall positive group dynamic development of the crew.

The major goal of this study was to specify the developmental trajectories for phonics and early text comprehension skills of children from kindergarten through third grade. Data from the Early Childhood Longitudinal Study (N = 12,261) were used in this study. The participants were divided into 3 school readiness groups based on an assessment of literacy skill development at the time of entrance into kindergarten. The different groups were tracked on phonics and text comprehension development through the third grade. Students in the average and high literacy readiness groups achieved high scores in decoding (phonics) by the end of the first grade. Students in the low readiness group did not match these scores until the third grade. Although the phonics gap was essentially closed in the third grade, a second, very significant text comprehension gap was exposed. The 3 readiness groups were analyzed to assess the relative contributions of parent education, income, and kindergarten literacy score to third-grade literacy achievement. The results of this study stress the need for speech-language pathologists to assess emergent literacy skills in their speech and language clients and to include appropriate literacy goals in the treatment regimen as a means for reducing the potential need for identification as learning disabled in reading in the later years of elementary school.

Background The Study to Explore Early Development (SEED) is designed to enhance knowledge of autism spectrum disorder characteristics and etiologies. Objective This paper describes the demographic profile of enrolled families and examines sociodemographic differences between children with autism spectrum disorder and children with other developmental problems or who are typically developing. Methods This multi-site case-control study used health, education, and birth certificate records to identify and enroll children aged 2–5 years into one of three groups: 1) cases (children with autism spectrum disorder), 2) developmental delay or disorder controls, or 3) general population controls. Study group classification was based on sampling source, prior diagnoses, and study screening tests and developmental evaluations. The child's primary caregiver provided demographic characteristics through a telephone (or occasionally face-to-face) interview. Groups were compared using ANOVA, chi-squared test, or multinomial logistic regression as appropriate. Results Of 2768 study children, sizeable proportions were born to mothers of non-White race (31.7%), Hispanic ethnicity (11.4%), and foreign birth (17.6%); 33.0% of households had incomes below the US median. The autism spectrum disorder and population control groups differed significantly on nearly all sociodemographic parameters. In contrast, the autism spectrum disorder and developmental delay or disorder groups had generally similar sociodemographic characteristics. Conclusions SEED enrolled a sociodemographically diverse sample, which will allow further, in-depth exploration of sociodemographic differences between study groups and provide novel opportunities to explore sociodemographic influences on etiologic risk factor associations with autism spectrum disorder and phenotypic subtypes.

2015-01-01

Background: Health policies are important instruments for improving population health. However, experience suggests that policies designed for the whole population do not always benefit the most vulnerable. Participation of vulnerable groups in the policy-making process provides an opportunity for them to influence decisions related to their health, and also to exercise their rights. This paper presents the findings from a study that explored how vulnerable groups and principles of human rights are incorporated into national sexual and reproductive health (SRH) policies of 4 selected countries (Spain, Scotland, Republic of Moldova, and Ukraine). It also aimed at discussing the involvement of vulnerable groups in SRH policy development from the perspective of policy-makers. Methods: Literature review, health policy analysis and 5 semi-structured interviews with policy-makers were carried out in this study. Content analysis of SRH policies was performed using the EquiFrame analytical framework. Results: The study revealed that vulnerable groups and core principles of human rights are differently addressed in SRH policies within 4 studied countries. The opinions of policy-makers on the importance of mentioning vulnerable groups in policy documents and the way they ought to be mentioned varied, but they agreed that a clear definition of vulnerability, practical examples, and evidences on health status of these groups have to be included. In addition, different approaches to vulnerable group’s involvement in policy development were identified during the interviews and the range of obstacles to this process was discussed by respondents. Conclusion: Incorporation of vulnerable groups in the SRH policies and their involvement in policy development were found to be important in addressing SRH of these groups and providing an opportunity for them to advocate for equal access to healthcare and exercise their rights. Future research on this topic should include representatives of vulnerable communities which could help to build a dialogue and present the problem from multiple perspectives. PMID:26673176

To explore the effect of in-home fortification of complementary feeding on intellectual development of Chinese children aged below 24 months. One thousand and four hundred seventy eight children aged 4-12 months were recruited and divided into study groups (formula 1 group and formula 2 group) and control group. In two study groups, in addition to the usual complementary food, children were fed with a sachet of fortified food supplement each day. Protein and micronutrients were provided in formula 1 group. Formula 2 group had the same energy intake as the formula 1 group . In addition to measurement of physical growth and detection of hemoglobin level, Development Quotient (DQ) or Intelligence Quotient (IQ) was assessed. The DQ of children aged below 24 months was 97.2, 95.5, and 93.8 in formula 1 group, formula 2 group and control group, respectively, and the differences were statistically significant (P < 0.05). The DQ of children in formula 1 group, formula 2 group, and control group was 92.7, 90.4, and 88.3 respectively in the first follow up showing statistically significant differences (P < 0.05). And, DQ of children in formula 1 group, formula 2 group and control group were 96.7, 94.5, and 93.7 respectively in the second follow up, showing statistically significant differences (P < 0.05). Full-IQ of children in the formula 1 group was 3.1 and 4.5 points higher than that in formula 2 group and in control group respectively. Verbal IQ of children in the formula 1 group was 2.1 and 5 points higher than that in formula 2 group and control group respectively. Performance IQ was 2.5 and 3.1 points higher than that in formula 2 group and control group respectively. All above mentioned comparisons were statistically significant. Fortification of complementary feeding showed persistent effect on intelligence development of young children which could persist to 6 years of age. The critical time for correction of anemia could be under 18 months.

Adequate physical fitness is essential for successful military service. Military organizations worldwide therefore make continuous efforts to improve their army's physical training (PT) programs. To investigate the effect of the training methods and the qualification of PT instructors on the development of recruits' physical fitness, the present study compared the outcomes of 2 training groups. Both study groups participated in approximately 145 minutes per week of PT. The control group executed the standard army PT prepared and supervised by army PT instructors. Content of the PT in the intervention group was similar to that of the control group, but their training sessions' methods were different. Their training sessions were organized, prepared, and delivered by more and better-qualified supervisors (tertiary-educated physical education teachers). After 10 weeks of training, the participants of the intervention group experienced a significantly greater physical fitness improvement than those of the control group (positive change in endurance 32 and 17%, balance 30 and 21%, and core strength 74 and 45%, respectively). In both groups, the recruits with the lowest initial fitness levels significantly increased their performance. In the intervention group, but not the control, one-third of the recruits with the highest initial fitness levels were able to further improve their general fitness performance. This study demonstrates that the training methods and quality of instruction during PT sessions are relevant for recruits' fitness development in basic military training.

The relationship between bile acid reflux into the stomach and the risk of atrophic gastritis and intestinal metaplasia is still not well understood. Towards obtaining a better understanding, concentrations of bile acids were measured. This study was carried out with the participation of 14 facilities in Japan, and 2283 samples were collected. The subjects with bile acid concentrations equal to or higher than the limit of detection were divided into four groups of equal size (group A: 0-25%, group B: 26-50%, group C: 51-75%, and group D: 76-100%). Thus, including the control group, there were five groups in total. The odds that the control group would develop atrophic gastritis and intestinal metaplasia was set as 1,and the odds ratios (OR) in groups A, B, C and D were calculated based on the odds in the control group. Regarding the development of atrophic gastritis, no increased risk was observed in either the Helicobacter pylori (H. pylori)-positive or -negative cases. The OR for the development of intestinal metaplasia were significantly higher, for both cases with and without H. pylori infection, in group D. High concentrations of bile acid seem to be associated with an elevated risk of intestinal metaplasia. © 2013 The Authors. Digestive Endoscopy © 2013 Japan Gastroenterological Endoscopy Society.

Malocclusion plays an important role in the development of periodontitis. Thus, by treating malocclusion, a good gingival health can be achieved. This study was conducted to establish the correlation between orthodontic tooth movement and periodontitis. This is a retrospective study conducted on 220 patients who underwent orthodontic treatment for malocclusion. They were divided into two groups: Group I patients were treated with fixed orthodontics, while group II patients received myofunctional appliances. The value for plaque, gingival recession, and tooth mobility significantly increased in group I patients. However, the difference was statistically nonsignificant in group II patients. The authors concluded that there is correlation between malocclusion and periodontitis. Malocclusion leads to periodontitis. Malocclusion is the main reason for the development of poor periodontal health. Combined effort has to be played by both periodontist and orthodontist for the treatment of various orthodontic-periodontal problems.

Enuresis is defined as the voluntary or involuntary repeated discharge of urine into clothes or bed after a developmental age when bladder control should be established. The present clinical study was planned to evaluate the effect of Divyadi Yoga along with counseling in the management of Shayyamutra. Total 40 selected cases were divided into two groups, i.e. 20 in each group. One group of children were given the trial drug Divyadi Yoga (D1) with counseling and other group of children were given placebo Divyadi Yoga (D2) with counseling. Divyadi Yoga was given in the dose of 3-6 gms. twice a day with luke warm water. The result of the study showed that groups provided a highly significant. PMID:22131688

Hepatic encephalopathy (HE) is challenging to identify in children with acute liver failure and was not a requirement for enrollment into the Pediatric Acute Liver Failure Study Group (PALFSG). The outcomes of PALFSG participants presenting with and without HE are presented. PALFSG participants were classified based on daily assessment of HE during the first 7 days following study enrollment: group 1-never developed HE; group 2-no HE at enrollment with subsequent HE development; and group 3-HE at study enrollment. Clinical and biochemical parameters and outcomes of death, spontaneous recovery, or liver transplantation were compared between groups. Data from 769 PALFSG (54% boys; median age 4.2 years; range 0-17.9 years) participants were analyzed, with 277 in group 1 (36%), 83 in group 2 (11%), and 409 in group 3 (53%). Mortality occurred in 11% of all participants and was highest among group 3 participants who demonstrated persistent grade III-IV HE (55%) or showed progression of HE (26%). Eleven (4%) group 1 participants died within 21 days of enrollment. Spontaneous recovery was highest in group 1 (79%) and lowest in group 2 (25%; P < 0.001). Mortality 21 days after enrollment was highest in participants enrolled with severe HE (grades III or IV) or demonstrating HE progression. Four percent of participants without recorded clinical HE in the 7 days after enrollment, however, died within 21 days. Improved assessment of neurological injury and pediatric acute liver failure prognostication schema are needed.

Participants (n = 36) with consistent Pre-conformist ego development levels during multiple adolescent assessments were studied to determine whether and how their ego levels had changed at age 25. Those (n = 12) whose ego levels remained at the Pre-conformist level were assigned to a life-course-persistent profound ego development arrest trajectory group; those (n = 24) whose ego levels reached the Conformist or Post-conformist level at age 25 were assigned to an adolescence-limited profound ego development arrest trajectory group. Analysis of predictors and age 25 correlates of group membership revealed that selected age 14 family interaction behaviors differentiated the two groups. At age 25, members of the adolescence-limited group showed superior performance on several measures of interpersonal and intrapersonal functioning. PMID:28154436

To study the effects of ethanol vapour exposure on development of atrial and ventricular septa of chick embryo. The experimental study was conducted at the College of Physicians and Surgeons, Islamabad, from 2006 to 2007. The experimental and control groups were further divided into three subgroups based on the day of sacrifice. The experimental group was exposed to ethanol vapours produced in a specially-designed vapour chamber and then compared with age-matched controls. There were 90 eggs in each of the two groups. The development of inter-ventricular septum completed at day 7 of development in chick embryo. Ethanol vapour exposure produced a small discontinuity at day 10 of development in a chick embryo which may be labelled as ventricular septal defect since ventricular development is completed by day 7. Interatrial septum formed till day 7 with small perforations which persisted till hatching. Ethanol vapour exposure may lead to ventricular septal defect.

Because in most cases the development of tinnitus is triggered by cochlear damage, there exists the opportunity to eliminate tinnitus while the cochlear lesion is still reversible. Therefore, we evaluated the therapeutic effects of various treatment modalities on acute subjective idiopathic tinnitus (SIT) and investigated prognostic factors affecting the treatment outcome. Prospective, controlled, double-blind trial. A total 107 patients who underwent treatment for unilateral SIT that had developed within the previous 3 months completed the study. The patients were randomly assigned into three groups according to the treatment modality: group I (n = 32), alprazolam orally for 3 months; group II (n = 35), as for group I plus four intratympanic dexamethasone (ITD) injections; and group III (n = 40), as for group II plus four intravenous injections of lipo-prostaglandin E(1) . The improvement rate of group II (75.8%) was significantly higher than that of group I (40.3%; P < .05), and there was no significant difference in the improvement rate of group III (50.0%) compared with groups I and II (P > .05). The cure rates of group II (25.8%) and group III (20.0%) were significantly higher than that of group I (9.8%; P < .05). There was a significant correlation between the cure rate and duration of symptoms. The results of the present study indicate that ITD injection plus alprazolam medication is the best treatment choice for acute SIT within 3 months of development.

In our previous study of 3-year-old children in a dioxin contamination hot spot in Vietnam, the high total dioxin toxic equivalent (TEQ-PCDDs/Fs)-exposed group during the perinatal period displayed lower Bayley III neurodevelopmental scores, whereas the high 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD)-exposed group displayed increased autistic traits. In autistic children, urinary amino acid profiles have revealed metabolic alterations in the amino acids that serve as neurotransmitters in the developing brain. Therefore, our present study aimed to investigate the use of alterations in urinary amino acid excretion as biomarkers of dioxin exposure-induced neurodevelopmental deficits in highly exposed 3-year-old children in Vietnam. A nested case-control study of urinary analyses was performed for 26 children who were selected from 111 3-year-old children whose perinatal dioxin exposure levels and neurodevelopmental status were examined in follow-up surveys conducted in a dioxin contaminated hot spot. We compared urinary amino acid levels between the following 4 groups: (1) a high TEQ-PCDDs/Fs and high TCDD-exposed group; (2) a high TEQ-PCDDs/Fs but low TCDD-exposed group; (3) a low TEQ-PCDDs/Fs exposed and poorly developed group; and (4) a low TEQ-PCDDs/Fs exposed and well-developed group. Urinary levels of histidine and tryptophan were significantly decreased in the high TEQ-PCDDs/Fs and high TCDD group, as well as in the high TEQ-PCDDs/Fs but low TCDD group, compared with the low TEQ-PCDDs/Fs and well-developed group. However, the ratio of histidine to glycine was significantly lower only in the high TEQ-PCDDs/Fs and high TCDD group. Furthermore, urinary histidine levels and the ratio of histidine to glycine were significantly correlated with neurodevelopmental scores, particularly for language and fine motor skills. These results indicate that urinary histidine is specifically associated with dioxin exposure-induced neurodevelopmental deficits, suggesting that urinary histidine may be a useful marker of dioxin-induced neurodevelopmental deficits and that histaminergic neurotransmission may be an important pathological contributor to dioxin-mediated neurotoxicity.

Young children with severe malnutrition usually have poor mental development. Psychosocial stimulation may reduce their cognitive deficit, but it is not usually provided. The aim of the study was to incorporate stimulation into the routine treatment of severely malnourished children in a nutrition unit and evaluate the impact on their growth and development. Time-lagged controlled study. Nutritional Rehabilitation Unit (NRU) in ICDDR,B Dhaka Hospital. Severely malnourished children, aged 6-24 months, admitted to the NRU were enrolled. All received standard nutritional care. A control group of 43 children was studied initially, followed by an intervention group of 54 children. The intervened mothers and children participated in daily group meetings and individual play sessions for 2 weeks in hospital and were visited at home for 6 months. Children's growth was measured and development assessed using the Bayley Scales of Infant Development. Twenty-seven children were lost to the study. In the remaining children, both groups had similar developmental scores and anthropometry initially. After 6 months, the intervention group had improved more than the controls did by a mean of 6.9 (P<0.001; 95% CI: 3.9, 10.0) mental and 3.1 (P=0.024; 95% CI: 0.4, 5.7) motor raw scores and a mean of 0.4 (P=0.029; 95% CI: 0.1, 0.8) weight-for-age z scores, controlling for background variables. Psychosocial stimulation integrated into treatment of severely malnourished children in hospital, followed by home visits for 6 months, was effective in improving children's growth and development and should be an integral part of their treatment.

Informal music activities such as singing may lead to augmented auditory perception and attention. In order to study the accuracy and development of music-related sound change detection in children with cochlear implants (CIs) and normal hearing (NH) aged 4-13 years, we recorded their auditory event-related potentials twice (at T1 and T2, 14-17 months apart). We compared their MMN (preattentive discrimination) and P3a (attention toward salient sounds) to changes in piano tone pitch, timbre, duration, and gaps. Of particular interest was to determine whether singing can facilitate auditory perception and attention of CI children. It was found that, compared to the NH group, the CI group had smaller and later timbre P3a and later pitch P3a, implying degraded discrimination and attention shift. Duration MMN became larger from T1 to T2 only in the NH group. The development of response patterns for duration and gap changes were not similar in the CI and NH groups. Importantly, CI singers had enhanced or rapidly developing P3a or P3a-like responses over all change types. In contrast, CI non-singers had rapidly enlarging pitch MMN without enlargement of P3a, and their timbre P3a became smaller and later over time. These novel results show interplay between MMN, P3a, brain development, cochlear implantation, and singing. They imply an augmented development of neural networks for attention and more accurate neural discrimination associated with singing. In future studies, differential development of P3a between CI and NH children should be taken into account in comparisons of these groups. Moreover, further studies are needed to assess whether singing enhances auditory perception and attention of children with CIs.

A study was conducted to investigated the intellectual sequelae of severe kwashiorkor among Nigerian children of school age. The design for the study had an experimental urban kwashiorkor (index) group and four control groups, namely, a sibling group, a lower class group, an upper class group, and a rural kwashiorkor group. Various psychological tests measuring specific intellectual abilities were administered to all of the subjects taking part in the study. The findings showed that the index group had lower levels of certain types of intellectual skill-specifically the higher cognitive skills-at school age than their siblings, and more so than other controls except their rural counterparts; males showed a tendency to be more affected by severe kwashiorkor with regard to mental development than their female counterparts; there was no relationship between scores in the psychological tests and the ages at which the index cases were admitted into hospital; the upper class was clearly superior in performance of the tests and also in measures of weight and head measurements when compared to all of the other groups; there was no relationship between head circumference and scores in the tests among subjects in the five groups.

The aim of this study was to evaluate the clinical efficacy and the effects on decreasing the recurrence of AFRS (allergic fungal rhinosinusitis) of a budesonide inhalation suspension delivered via transnasal nebulization to patients following endoscopic sinus surgery. Thirty-five patients were recruited into this study. Final diagnoses were reached using Bent and Kuhn's criteria. The eligible patients were randomly divided into two groups: the budesonide transnasal nebulization group (group A) and the topical nasal steroids group (group B). Nasal symptoms, Lund-Mackay scores, and Kupferberg grades were evaluated before surgery, after surgery and during the follow-up to assess the effects of these two approaches. A total of 30 patients with AFRS who were eligible were included in the study. Four of the 15 patients in group B (26.67%) developed recurrent disease, whereas no patients in group A developed recurrent disease. This difference was statistically significant (p=0.032). Nebulized budesonide is an effective and safe treatment for patients with AFRS following endoscopic sinus surgery, as evidenced by the reduced recurrence rate observed in the budesonide transnasal nebulization group relative to the topical nasal steroids group.

Alopecia areata (AA) is an autoimmune disease characterized by noncicatricial hair loss localized on hair, beard, mustache, eyebrow, eyelash, and sometimes on the body. Although etiopathogenesis is not fully understood, many studies show remarkable associations between various diseases and ABO blood groups. However, there is no study with AA and blood groups. Healthy people and patients with AA were included in this study. A total of 155 patients with AA and 299 healthy controls were included in the study. ABO blood group distribution in patients with AA and distribution of healthy donors were similar. However, Rhesus factor positivity in the AA group was significantly higher than in healthy donors. The relationship between stress and AA was high as known. But, ABO blood group and Rhesus factor were not in a significant connection with stress. We conclude that there was no association between ABO blood group and AA, but the observed distribution of Rhesus blood group differed slightly but significantly from that of the healthy population. The result of the study shows a small but statistically significant difference in the Rh blood group between patients with AA and the healthy population blood groups. This result is important because it suggests that genetic factors may influence the development of AA. The role of blood groups in the development of AA remains to be determined. We believe that the studies which will be carried out in other centers with wider series will be more valuable to support this hypothesis. © 2018 Wiley Periodicals, Inc.

Androgens may directly modulate early ovarian follicular development in preantral stages and androgen excess before puberty may disrupt this physiological process. Therefore, the aim of this study was to investigate the dynamics of follicular morphology and circulating androgen and estradiol levels in prepubertal Wistar rats acutely exposed to androgens. Prepubertal female Wistar rats were distributed into three groups: control, equine chorionic gonadotropin (eCG) intervention and eCG plus dehydroepiandrosterone (DHEA) intervention (eCG+DHEA). Serum DHEA, testosterone and estradiol levels were determined, and ovarian morphology and morphometry were assessed. The eCG+DHEA group presented increased serum estradiol and testosterone levels as compared with the control group (P<0.01), and higher serum DHEA concentration v. the eCG-only and control groups (P<0.01). In addition, the eCG+DHEA group had a higher number of, and larger-sized, primary and secondary follicles as compared with the control group (P<0.05). The eCG group presented intermediate values for number and size of primary and secondary follicles, without significant differences as compared with the other two groups. The number of antral follicles was higher in the eCG+DHEA and eCG groups v. controls (P<0.05). The number of primordial, atretic and cystic follicles were similar in all groups. In conclusion, the present experimental model using an acute eCG+DHEA intervention was useful to investigate events involved in initial follicular development under hyperandrogenic conditions, and could provide a reliable tool to study defective follicular development with possible deleterious reproductive consequences later in life.

This study of a prospective and cross-sectional nature compared the motor and cognitive development of HIV-exposed and unexposed infants in their first 18months of age. 40 infants exposed to HIV and antiretroviral therapy (Experimental Group - EG) and 40 unexposed infants (Control Group - CG) participated in the study. They were divided into four age groups of 4, 8, 12 and 18months old, with 10 infants from EG and 10 from CG in each group. The infants were evaluated once on motor and cognitive development by the Bayley Scale of Infant and Toddler Development. Performance category grading and comparisons among scaled score, composite score and percentile rank were held. There was significant group effect for scores in motor and cognitive domains showing lower scores for EG regardless of age. In comparison to the CG, the EG presented lower scores for cognitive domain at 8 and 18months. In the performance categories, all infants were classified at or above the average for motor and cognitive development, except of one EG-18month old infant classified as borderline for motor development. Infants exposed to HIV and antiretroviral therapy own adequate cognitive and motor development in the first 18months. However, the lower scores found, particularly on the 8th and 18th month for cognitive development, may indicate future problems, highlighting the need for systematic follow-up of this population.

The development of imitation during the second year of life plays an important role in domains of socio-cognitive development such as language and social learning. Deficits in imitation ability in persons with autism spectrum disorder (ASD) have also been repeatedly documented from toddlerhood into adulthood, raising the possibility that early disruptions in imitation contribute to the onset of ASD and the deficits in language and social interaction that define the disorder. This study prospectively examined the development of imitation between 12 and 24 months of age in 154 infants at familial risk for ASD and 78 typically developing infants who were all later assessed at 36 months for ASD or other developmental delays. The study established a developmental measure of imitation ability, and examined group differences over time, using an analytic Rasch measurement model. Results revealed a unidimensional latent construct of imitation and verified a reliable sequence of imitation skills that was invariant over time for all outcome groups. Results also showed that all groups displayed similar significant linear increases in imitation ability between 12 and 24 months and that these increases were related to individual growth in both expressive language and ratings of social engagement, but not fine motor development. The group of children who developed ASD by age 3 years exhibited delayed imitation development compared to the low-risk typical outcome group across all time-points, but were indistinguishable from other high-risk infants who showed other cognitive delays not related to ASD.

The impact of being an adolescent and socio-demographic parameters on depression development during pregnancy were evaluated in this study. Between September 2010 and September 2011, 105 consecutive adolescent women ≤ 17 years of age were defined as the study group and 105 consecutive pregnant women over 18 years of age and matched for gestational age, were defined as the control group. Groups were compared according to depression development. The predictors of depression were analyzed by regression analysis. Median Beck Depression Inventory-II (BDI-II) scores in adolescent and control groups were 16 and 6, respectively. The difference was statistically significant. In the adolescent group, 39.0% of patients had mild depression, 37.1% moderate, and 10.5% had severe depression. Only 4.8% of patients in the control group had mild depression while none of the control cases had moderate or severe depression. Multivariate analysis showed that most important factor that was associated with depression development during pregnancy was being an adolescent. Depression risk was increased 18.2-fold in adolescent patients with pregnancy. Therefore psychiatric evaluation should be considered for these patients.

To estimate the achievement of an educative strategy that promoted participation of the development of the clinical aptitude of undergraduate medical students with regard to patients with diabetes. We conducted a quasi-experimental study with two groups of undergraduate medical students. We validated an instrument to explore clinical attitude concerning diabetes mellitus (ACDIME) with 30 items for each of six indicators. The instrument was applied at two general hospitals, before and after carrying out the educative strategies. In the experimental group, we conducted an educative strategy that promotes participation in developing clinical aptitude, while the customary strategy was developed in the control group. ACDIME consistency was 0.80. Both study groups were similar before the educative strategies (p = 0.165). Statistically significant differences existed after the strategies in all indicators were evaluated, in favor of the experimental group. The tendency to change, with a criterion of 50% or more, was only statistically significant in the experimental group (p < 0.0001). The ACDIME instrument is valid and reliable. The educative strategy that promoted participation is clearly superior to the customary strategy with regard to achievement.

This study compares the effectiveness of group health supervision (three or four families counseled simultaneously) with traditional visits in conveying knowledge of child health and development, increasing perceived maternal support, and mitigating maternal depression. Subjects were recruited from a predominantly white, middle-class, suburban/rural pediatric practice. Twenty-five families were allocated to group health supervision and 25 to individual visits. A questionnaire covering knowledge of child health and development (CHDQ), the Maternal Social Support Index (MSSI), and the Center for Epidemiologic Studies Depression Scale (CESD) were administered to both groups before their 2-month and after their 10-month visits. A subset of these charts was reviewed for problem visits between 2 and 6 months. As compared with families having traditional visits, families who received the group intervention did at least as well in acquiring knowledge of child care and development and, although not statistically significant, tended to recover from postpartum depression faster and deal better with minor illnesses. The investigators found group child health supervision to be a pleasant and effective method of health care delivery.

Reporting Standards for Research in Psychology

2010-01-01

In anticipation of the impending revision of the Publication Manual of the American Psychological Association, APA’s Publications and Communications Board formed the Working Group on Journal Article Reporting Standards (JARS) and charged it to provide the board with background and recommendations on information that should be included in manuscripts submitted to APA journals that report (a) new data collections and (b) meta-analyses. The JARS Group reviewed efforts in related fields to develop standards and sought input from other knowledgeable groups. The resulting recommendations contain (a) standards for all journal articles, (b) more specific standards for reports of studies with experimental manipulations or evaluations of interventions using research designs involving random or nonrandom assignment, and (c) standards for articles reporting meta-analyses. The JARS Group anticipated that standards for reporting other research designs (e.g., observational studies, longitudinal studies) would emerge over time. This report also (a) examines societal developments that have encouraged researchers to provide more details when reporting their studies, (b) notes important differences between requirements, standards, and recommendations for reporting, and (c) examines benefits and obstacles to the development and implementation of reporting standards.

The study involved 67 patients with odontogenic cysts (OC) aged 18 to 45 years, who were divided into groups: Group 1 (n = 67) patients with OC aged 18 to 45 years, group 2--control group, consisted of 20 healthy persons of similar age. We studied the characteristics of immune status and immunoreactivity in patients with odontogenic cysts. Condition of cellular and humoral immunity was assessed by using the methods of direct rosette developing with erythrocytes coated with monoclonal antibodies to CD3+, CD4+, CD8+, CD22+, CD4/CD8 indicators of immunoregulatory index and phagocytic immunity. State of nonspecific resistance was studied by determining the phagocytic activity of neutrophils and their oxygen dependent metabolism in NBT test. The concentration of cytokines (IL-6 and IL-4) in serum was determined by ELISA. During the study we found that in patients with (OC) developed significant changes in the structure of the immune response at the cellular as well as at the humoral level that makes it necessary to develop new individualized preventive measures along with existing therapies OC.

Health promotion programs provide information, education for health and opportunity for the development of the skills that people need to make healthy choices. The current climate of health care practice also directs its focus to the needs and wants of the health care consumers. This entails active input from the target group. The present study used focus groups in an attempt to ensure input from women in early postpartum into the development of a postpartum continence promotion program. The focus groups revealed anomalies in women's perceived susceptibility to, and knowledge about, urinary incontinence and pelvic floor exercises, while highlighting other areas of need. Focus groups proved an invaluable tool in the development of a more effective physiotherapy continence promotion program.

Does electroconvulsive therapy cause epilepsy?

Electroconvulsive therapy (ECT) has been mentioned as a risk factor for epilepsy in some texts. This observation is based on isolated case reports and 2 studies done in 1980s. Since 1983, no study was done on this topic. The objective of the current study was to find out the incidence of spontaneous seizures after ECT. The study was done in Central Institute of Psychiatry, India. It was a retrospective cohort study where files of the patients receiving unmodified ECT during 1990 to 1995 were reviewed over approximately the next 10 years. Patients having the risk factors for spontaneous seizures like past and family history of seizure, substance abuse, and organicity were excluded from the study group. For minimizing the confounding effect of concurrent psychotropic drugs, an age-, sex-, and diagnosis-matched control group was selected. This group consisted of patients admitted during the same time and treated with similar drugs but no ECT. No report of spontaneous seizure was found in the study group of 619 patients. One patient who was excluded from the study group due to suspected neurosyphilis developed recurrent seizures 1 month after ECT. Two patients in the control group had single occasion convulsion with no further recurrence even with continuation of similar drugs. Electroconvulsive therapy has not been found to cause epilepsy. Patient's underlying organic condition may influence development of seizures.

In many parts of the world contact with infected livestock may involve a serious risk of the spread of human brucellosis. Partial control of bovine brucellosis has been achieved by slaughter of infected herds and immunization of cattle with Brucella abortus strain 19 living vaccine. However, in areas where such measures are unpractical there remains a need for protection of humans. This study compares the safety of two living Brucella vaccine preparations in human volunteers. Some 32 healthy male volunteers with no evidence of past exposure to brucellosis were divided into two comparable groups; one group received 19-BA vaccine derived from Br. abortus and the other received Rev 1 vaccine derived from Br. melitensis. Detailed studies over a six-month period of the clinical effects, bacteraemia, Brucella agglutinin response and dermal hypersensitivity revealed striking differences between the two groups. Two of the 16 men in the 19-BA group developed acute brucellosis, and another had a positive blood culture. In the Rev 1 group, 11 of 16 developed acute brucellosis, and brucellae were recovered from 12. All 32 men developed Brucella agglutinins, the Rev 1 group having higher titres. Dermal hypersensitivity occurred in all of the Rev. 1 group but in only nine of the 19-BA group. Tetracycline treatment in all the Rev 1 group and in the two brucellosis cases in the 19-BA group resulted in complete recovery. The authors conclude from this study that neither the Rev 1 vaccine nor the 19-BA vaccine inoculated subcutaneously is sufficiently safe in the dosage used to warrant being used for vaccination of humans for prophylactic purposes.

Multidisciplinary guideline development groups (GDGs) have considerable influence on UK healthcare policy and practice, but previous research suggests that research evidence is a variable influence on GDG recommendations. The Evidence into Recommendations (EiR) study has been set up to document social-psychological influences on GDG decision-making. In this paper we aim to evaluate the relevance of existing qualitative methodologies to the EiR study, and to develop a method best-suited to capturing influences on GDG decision-making. A research team comprised of three postdoctoral research fellows and a multidisciplinary steering group assessed the utility of extant qualitative methodologies for coding verbatim GDG meeting transcripts and semi-structured interviews with GDG members. A unique configuration of techniques was developed to permit data reduction and analysis. Our method incorporates techniques from thematic analysis, grounded theory analysis, content analysis, and framework analysis. Thematic analysis of individual interviews conducted with group members at the start and end of the GDG process defines discrete problem areas to guide data extraction from GDG meeting transcripts. Data excerpts are coded both inductively and deductively, using concepts taken from theories of decision-making, social influence and group processes. These codes inform a framework analysis to describe and explain incidents within GDG meetings. We illustrate the application of the method by discussing some preliminary findings of a study of a National Institute for Health and Clinical Excellence (NICE) acute physical health GDG. This method is currently being applied to study the meetings of three of NICE GDGs. These cover topics in acute physical health, mental health and public health, and comprise a total of 45 full-day meetings. The method offers potential for application to other health care and decision-making groups.

The purpose of the study was to analyze the development of nursing practice in family medicine groups (FMGs). The two-year case study consisted of 73 semi-directed interviews ofnurses, physicians and managers in five FMGs. The findings led to three main observations: nursing practice varies considerably from one FMG to another, the development of nurses' practice seems to be associated with the development of a collaborative relationship, and the satisfaction of the professionals in the FMG, nurses in particular, depends on the type of practice. It is important to implement measures to encourage the optimal use ofnurses' skills in a FMG.

Bredariol, Celso Simoes; Magrini, Alessandra

In developing countries, environmental conflicts are resolved mainly in the political arena. In the developed nations, approaches favoring structured negotiation support techniques are more common, with methodologies and studies designed especially for this purpose, deriving from Group Communications and Decision Theory. This paper analyzes an environmental dispute in the City of Rio de Janeiro, applying conflict analysis methods and simulating its settlement. It concludes that the use of these methodologies in the developing countries may be undertaken with adaptations, designed to train community groups in negotiating while fostering the democratization of the settlement of these disputes.

To compare the caries preventive effect of a chlorhexidine/thymol-containing antibacterial varnish with a fluoride varnish when topically applied during the eruption of permanent molars. The study group consisted of 189 patients, 5-14 years of age, with one 1st or 2nd permanent molar in the process of eruption. After stratification for type of molar and stage of eruption, the patients were randomised to either quarterly topical applications with an antibacterial varnish (Cervitec(®) Plus; CV group) or biannual applications with a fluoride varnish plus biannual treatments with placebo varnish (Fluor Protector; FV group). The duration of the study was 2 years. The primary endpoint was caries incidence (initial and cavitated) in the erupting molars and the secondary outcome was salivary mutans streptococci (MS) counts. The groups were balanced with respect to socio-economy, oral hygiene, dietary habits and caries experience at baseline. The dropout rate was 11.6 %. The caries incidence was low (< 10 %) in both groups and there was no significant difference between the CV and FV groups with respect to occlusal caries development in the erupting molars (relative risk 1.08, 95 % CI 0.94-1.25). Significantly lower levels of salivary MS were disclosed in the CV group at the end of the study (p < 0.05). No difference in occlusal caries development in young permanent molars was displayed after topical applications of either a chlorhexidine/thymol varnish or a fluoride varnish during tooth eruption.

Understanding links between behaviour change techniques (BCTs) and mechanisms of action (the processes through which they affect behaviour) helps inform the systematic development of behaviour change interventions. This research aims to develop and test a methodology for linking BCTs to their mechanisms of action. Study 1 (published explicit links): Hypothesised links between 93 BCTs (from the 93-item BCT taxonomy, BCTTv1) and mechanisms of action will be identified from published interventions and their frequency, explicitness and precision documented. Study 2 (expert-agreed explicit links): Behaviour change experts will identify links between 61 BCTs and 26 mechanisms of action in a formal consensus study. Study 3 (integrated matrix of explicit links): Agreement between studies 1 and 2 will be evaluated and a new group of experts will discuss discrepancies. An integrated matrix of BCT-mechanism of action links, annotated to indicate strength of evidence, will be generated. Study 4 (published implicit links): To determine whether groups of co-occurring BCTs can be linked to theories, we will identify groups of BCTs that are used together from the study 1 literature. A consensus exercise will be used to rate strength of links between groups of BCT and theories. A formal methodology for linking BCTs to their hypothesised mechanisms of action can contribute to the development and evaluation of behaviour change interventions. This research is a step towards developing a behaviour change 'ontology', specifying relations between BCTs, mechanisms of action, modes of delivery, populations, settings and types of behaviour.

The effects of professional development related to classroom assessment on student achievement in science

NASA Astrophysics Data System (ADS)

Mazzie, Dawn Danielle

This study investigated the relationship between students' standardized test scores in science and (a) increases in teacher assessment literacy and (b) teacher participation in a Teacher Quality Research (TQR) project on classroom assessment. The samples for these studies were teachers from underperforming schools who volunteered to take part in a professional development program in classroom assessment. School groups were randomly assigned to the treatment group. For Study 1, teachers in the treatment received professional development in classroom assessment from a trained assessment coach. Teachers in the control received no professional development. For Study 2, teachers in Treatment 1 received professional development in classroom assessment from a trained assessment coach and teachers in Treatment 2 received professional development in classroom assessment from a facilitator with one day of training. Teachers in both groups completed a measure of assessment literacy, the Teacher Quality Research Test of Assessment Literacy Skills (TQR_TALS), prior to the beginning and then again at the conclusion of the four month professional development program. A hierarchical linear model (HLM) analysis was conducted to determine the relationship between students' standardized test scores in science and (a) increases in teacher assessment literacy and (b) teacher TQR status. Based upon these analyses, the professional development program increased teachers' assessment literacy skills; however, the professional development had no significant impact on students' achievement.

Background: Support groups for families of persons with mental illness are emerging as significant components in psychosocial rehabilitation programmes. Aim: To ascertain the expectations of family members who attend family support group meetings and to find out the efficacy of such programmes. Methods: The data were collected from support group members using a semi-structured interview schedule. The study sample (n=20) was drawn from family members who attended the support group meetings regularly for a minimum period of 6 months. Data analysis was done using percentile. Results: Analysis of the data revealed that members attending the support group meetings expected to get more information about the illness, develop skills to cope with problems at home and learn skills to deal with the ill person. An important finding of the study was that the members developed a ‘feeling of togetherness’ as a result of being a member of a group with common aims. Conclusion: Participation in a support group meeting positively affects key variables in the participant's adaptation to mental illness in a relative. PMID:20814460

The use of surface electromyography (sEMG) recorded during ambulation has provided valuable insight into motor development and changes with age in the pediatric population. However, no studies have reported sEMG differences with age in the children with cerebral palsy (CP). In this study, data from 50 children were divided retrospectively into four groups, representing either an older (above the age of 7 years) or younger (below the age of 7 years) age group with either typical development (TD) or CP. Data were analyzed from 16 children in the younger age group with TD, and eight in the older age group with TD. Data were also available from 14 in the younger age group with CP, and 12 in the older age group with CP. SEMG signals from the rectus femoris (RF) and medial hamstring (MH) were analyzed using wavelet techniques to examine time-frequency content. RF muscle activity was statistically different between all groups (p<0.001), with an elevated instantaneous mean frequency (IMNF) in the older TD group than the younger TD group, an elevated IMNF in the younger CP group than the older CP group, and elevated IMNF in both CP groups compared to both TD groups. Activity for the MH muscle followed the same pattern except for the CP young and old group comparison, which indicated no difference. The results indicate that differences in neuromuscular activation exist between younger and older groups of children with both TD and CP, and may provide new insight into muscle activity pattern changes during the development of walking.

Recognizing facial expressions is an important social skill. In some psychological disorders such as schizophrenia, loss of this skill may complicate the patient's daily life. Prior research has shown that information technology may help to develop facial expression recognition skills through educational software and games. To examine if a computer game designed for teaching facial expressions would improve facial expression recognition skills of patients with schizophrenia. We developed a website composed of eight serious games. Thirty-two patients were given a pre-test composed of 21 facial expression photographs. Eighteen patients were in the study group while 14 were in the control group. Patients in the study group were asked to play the games on the website. After a period of one month, we performed a post-test for all patients. The median score of the correct answers was 17.5 in the control group whereas it was 16.5 in the study group (of 21) in pretest. The median post-test score was 18 in the control group (p=0.052) whereas it was 20 in the study group (p<0.001). Computer games may be used for the purpose of educating people who have difficulty in recognizing facial expressions.

Mean transthoracic electrical impedance (impedance) which is inversely related to intrathoracic extravascular fluid volume was measured in 121 normal healthy volunteers at sea-level and at 3658 metres altitude. Fifty (group A) reached the high altitude location after an hour's journey in a pressurised aircraft. Twenty-five (group D) underwent slow road ascent including acclimatisation en route. Thirty permanent residents (group B) and 16 temporary residents at high altitude (group C) were also studied. Serial studies in the 30 subjects of group A who developed symptoms of high altidue sickness showed a significant decrease of impedance up to the fourth day of exposure to high altitude which later returned to normal. The 4 volunteers who developed severe symptoms showed the largest drop in impedance. A case of acute pulmonary oedema developing at 4300 metres showed an impedance value of 24-1 ohms on admission. After effective treatment the impedance increased by 11-9 to 36-0 ohms. Twenty asymptomatic subjects of group A and 25 of group D showed a small average increase in impedance values at high altitude. These obstructions suggest that measurement of transthoracic electrical impedance may be a valuable means of detecting incipient high altitude pulmonary oedema.

The purpose of this study was to develop an integrated internet addiction prevention program and test its effects on the self-regulation and internet addiction of elementary students who are at risk for internet addiction. A quasi-experimental study with a nonequivalent control group pretest-posttest design was used. Participants were assigned to the experimental group (n=28) or control group (n=28). Contents of the program developed in this study included provision of information about internet addiction, interventions for empowerment and methods of behavioral modification. A pre-test and two post-tests were done to identify the effects of the program and their continuity. Effects were testified using Repeated measures ANOVA, simple effect analysis, and Time Contrast. The self-regulation of the experimental group after the program was significantly higher than the control group. The score for internet addiction self-diagnosis and the internet use time in the experimental group were significantly lower than the control group. The effects of the integrated internet addiction prevention program for preventing internet addiction in elementary students at risk for internet addiction were validated.

The aim of this work was to investigate the value of laparoscopic ovarian drilling (LOD) compared with GnRH antagonist flexible protocol combined with cabergoline (Cb), as a prophylaxis against the re-development of ovarian hyperstimulation syndrome (OHSS) in women with clomiphene citrate-resistant polycystic ovary disease (CCR-PCOD) who had severe OHSS before in a previous ICSI cycle. It is a prospective controlled study, where 250 CCR-PCOD women (n = 250) with a history of severe OHSS before, had been recruited for the study. LOD had been performed for 120 (n = 120) of the recruited women before ovarian induction, and considered as group A. GnRH antagonist (Cetrotide 0.25 mg) was added when a leading follicle reaches 14-16 mm combined with oral Cb in a dose 0.5 mg a day before hCG, and for 8 d for another 130 (n = 130) women, and considered as group B. Pregnancy was diagnosed with BhCG level ≥25 IU/L, ± 14 d after embryo transfer, followed with transvaginal ultrasound scanning (TVS) 2 weeks later to confirm intra-uterine pregnancy (IUP). Women were followed up weekly for 3 months for the possible development of any signs and symptoms of OHSS. None of the participants in group A developed severe OHSS, and only six women (5%) developed mild to moderate OHSS. The incidence of severe OHSS was significantly higher (n = 3, 15%) in group B compared with group A (p < .001). Another (n = 17, 13.3%) women in group B developed mild to moderate OHSS. The probability of developing severe OHSS was also significantly higher in group B as well (p = .031). Pregnancy rate (PR) was significantly higher in group A more than group B (67% versus 39%, respectively), and all were single intrauterine pregnancies (IUP) and all developed after fresh embryo transfer (ET), compared with frozen embryo transfer (FET) which was performed in 42 cases in group B after postponing ET due to significantly severe OHSS developed. LOD could be considered a good prophylactic measure against OHSS, in addition to improving the total outcome of IVF cycles in women with CCR-PCOS.

Structural and functional studies of a family of Dictyostelium discoideum developmentally regulated, prestalk genes coding for small proteins.

Vicente, Juan J; Galardi-Castilla, María; Escalante, Ricardo; Sastre, Leandro

2008-01-03

The social amoeba Dictyostelium discoideum executes a multicellular development program upon starvation. This morphogenetic process requires the differential regulation of a large number of genes and is coordinated by extracellular signals. The MADS-box transcription factor SrfA is required for several stages of development, including slug migration and spore terminal differentiation. Subtractive hybridization allowed the isolation of a gene, sigN (SrfA-induced gene N), that was dependent on the transcription factor SrfA for expression at the slug stage of development. Homology searches detected the existence of a large family of sigN-related genes in the Dictyostelium discoideum genome. The 13 most similar genes are grouped in two regions of chromosome 2 and have been named Group1 and Group2 sigN genes. The putative encoded proteins are 87-89 amino acids long. All these genes have a similar structure, composed of a first exon containing a 13 nucleotides long open reading frame and a second exon comprising the remaining of the putative coding region. The expression of these genes is induced at10 hours of development. Analyses of their promoter regions indicate that these genes are expressed in the prestalk region of developing structures. The addition of antibodies raised against SigN Group 2 proteins induced disintegration of multi-cellular structures at the mound stage of development. A large family of genes coding for small proteins has been identified in D. discoideum. Two groups of very similar genes from this family have been shown to be specifically expressed in prestalk cells during development. Functional studies using antibodies raised against Group 2 SigN proteins indicate that these genes could play a role during multicellular development.

Preeclampsia and intrauterine growth restriction are two separate disease entities that, according to numerous reports, share the same pathogenesis. In both, angiogenesis disorders and generalized inflammation are the dominant symptoms. In this study, we hypothesized that both diseases demonstrate the same profile in early preeclampsia, late preeclampsia, and intrauterine growth restriction patients, with the only difference being the degree of exacerbation of lesions. One hundred sixty-seven patients were enrolled in the study and divided into four groups: early preeclampsia, late preeclampsia, and intrauterine growth restriction groups, and one control group. Concentrations of the angiogenesis and inflammatory markers soluble fms-like tyrosine kinase receptor 1, placental growth factor, high-sensitivity C-reactive protein, and interleukin-6 were determined, and the behavior of these markers and correlations among them were studied. Higher concentrations of soluble fms-like tyrosine kinase receptor 1, high-sensitivity C-reactive protein, and interleukin-6 and a lower concentration of placental growth factor were observed in the study groups compared with the control group. No differences in concentrations of the studied markers were found among the study groups but significant correlations were observed. The higher values for the angiogenesis and inflammatory markers both in preeclampsia patients and patients with intrauterine growth restriction of placental origin compared with the control group suggest the existence of the same underlying disorders in the development of these pathologies. The observed mutual correlations for disordered angiogenesis and inflammatory markers are suggestive of a mutual relationship between these processes in the development of pathologies evolving secondary to placental ischemia. The same lesion profile was observed for both preeclampsia and 'placental' intrauterine growth restriction patients, which could be used in developing common diagnostic criteria for pregnant patients.

The objective of this study was to develop a subtle self-report scale-the Subtle ADHD Malingering Screener (SAMS)-to screen for malingering among individuals reporting symptoms of attention deficit/hyperactivity disorder (ADHD). This study employed a cross-sectional experimental design with an ADHD group, a control group-comprising individuals without ADHD-and a malingering group-comprising individuals without ADHD who were instructed to feign ADHD in their responses. Factor analysis and psychometric testing were conducted to develop a final scale that could distinguish the malingering from the other groups. A 10-item, two-factor solution was obtained for the SAMS, with a sensitivity of 90.3% and specificity of 80.1%. The SAMS presents an innovative approach to help reduce overdiagnosis of ADHD and misuse of prescription stimulants. The efficient, straightforward form of the measure particularly enhances its potential application in both medical and psychosocial clinical settings.

An X-ray computed-tomographic examination of nest-gallery development from timbers naturally infested by foraging groups of Incisitermes minor colonies was conducted. This study documents the colonization process of I. minor to new timbers and how the isolated groups maintain their nest-gallery system. The results suggested that development of a nest-gallery within a suitable wood item is not random, but shows selection for softer substrate and other adaptations to the different timber environments. Stigmergic coordinations were expressed in dynamic changes of the nest-gallery system; indicated by fortification behavior in sealing and re-opening a tunnel approaching the outer edge of the timber, and accumulating fecal pellets in particular chambers located beneath the timber surface. The study also examines the caste composition of isolated groups to discover how I. minor sustains colonies with and without primary reproductives. PMID:27455332

Microsatellite markers were developed for the Pilosella alpicola group (Asteraceae), comprising four closely related species distributed in subalpine areas of Europe. These species are believed to have diverged recently, but display contrasting cytogeographic patterns and variation in breeding systems, representing a promising model system for studying plant speciation, adaptation, and recent polyploidization. We developed 17 microsatellite markers for the P. alpicola group using 454 sequencing. Sixteen markers were polymorphic, with the number of alleles per locus ranging from seven to 16 and observed and expected heterozygosity ranging from 0.45 to 0.84 and 0.72 to 0.92, respectively. Ten and five loci amplified in the related species, P. echioides and P. officinarum, respectively, but only two in Andryala and one in Hieracium s. str. The developed microsatellite markers have high potential to become useful tools to study microevolutionary processes in the P. alpicola group and related Pilosella species.

This paper reports on a project that involved a number of agencies and groups, including older people, working together to examine and develop practice in an area of shared concern -- going home from hospital. The project was stimulated by a 'whole-system event', and was based on appreciative inquiry (AI) methodology, which has roots in both action research and organisational development. In AI, the research is directed towards appreciating what it is about the social world that is positive, and exploring this. The study was planned around three workshops to streamline data collection and analysis. Group members were also required to carry out some activities between workshops. Invitations were sent out to groups and individuals previously identified as involved or interested in the discharge process across one health district (n = 71). Workshop one discussed the planned research schedule, and introduced the basic concepts of AI. This workshop also took participants through the interview process. Each participant was asked to undertake two interviews. Thirty-five individual interviews and one focus group were completed. At workshop two, interview data were analysed by the group using the nominal group technique. Subsequent group discussion produced 'provocative propositions'. At the third workshop, provocative propositions were developed into action plans. This paper gives an overview of the study, and explores some of the issues involved when working with service users and providers as co-researchers.

The aim of this study was to investigate factors contributing to job satisfaction at different career stages, among private practice physiotherapists in Australia. Qualitative case study design utilising focus groups. Sixteen participants allocated to 3 focus groups: new graduates (n = 6), post graduates (n = 5) and practice owners (n = 5). Focus groups were transcribed verbatim and a thematic analysis was undertaken to determine themes and subthemes from each focus group. The key themes identified within each focus group included the role of peer support and mentoring, professional development, professional relationships, new graduate employment issues and career pathways within private practice. In particular, issues surrounding the new graduate experience in private practice were explored, with all groups noting lack of support and financial pressures were of concern. Findings demonstrated that new graduates are underprepared to work in private practice and modifications to the delivery of peer support, mentoring and professional development is required. Key recommendations include physiotherapy undergraduate program reform to reflect industry requirements in private practice, an increase in private practice clinical placement numbers, as well as streamlining the physiotherapy profession to improve career development pathways.

The purpose of this study is to observe the affection of different clinical surgeries on alar nasal cartilages' growth and development. The experimental results can provide some theory basis for clinical surgeries. Twenty-eight New Zealand immature rabbits were used in this study, and divided into normal control group, hidden dissection group and cutting off alar nasal cartilages group randomly, which included 4,12 and 12 rabbits, separately. Arc incision were made on the mucous membrane of nasal cavity,and then dissect the alar nasal cartilages hidden or cut off the alar nasal cartilages, separately. The growth and development of the alar cartilage were observed at different stages after the surgery using histological and immuno-histochemical methods. Four weeks, eight weeks, twelve weeks and sixteen weeks after surgery, there were no significant differences in the indexes of chondrocytes between hidden dissection group and control group. In cutting off alar nasal cartilages group, fiber tissue were observed in the vacancy left after being cut off cartilages, and even mucous membrane tissue could be seen in some slices. There is no adverse influence on the growth and development of the alar cartilage after being hidden dissected. Contrarily, the restoring capability of transparent cartilage cannot counteract the injury resulted form the surgery after the alar nasal cartilages being cut off.

The present study aims to test whether deaf children with unilateral cochlear implantation (CI) have higher intelligence quotients (IQ). We also try to find out the predictive factors of intelligence development in deaf children with CI. Totally, 186 children were enrolled into this study. They were divided into 3 groups: CI group (N = 66), hearing loss group (N = 54) and normal hearing group (N = 66). All children took the Hiskey-Nebraska Test of Learning Aptitude to assess the IQ. After that, we used Deafness gene chip, Categories of Auditory Performance (CAP) and Speech Intelligibility Rating (SIR) methods to evaluate the genotype, auditory and speech performance, respectively. At baseline, the average IQ of hearing loss group (HL), CI group, normal hearing (NH) group were 98.3 ± 9.23, 100.03 ± 12.13 and 109.89 ± 10.56, while NH group scored higher significantly than HL and CI groups (p < 0.05). After 12 months, the average IQ of HL group, CI group, NH group were99.54 ± 9.38,111.85 ± 15.38, and 112.08 ± 8.51, respectively. No significant difference between the IQ of the CI and NH groups was found (p > 0.05). The growth of SIR was positive correlated with the growth of IQ (r = 0.247, p = 0.046), while no significant correlation were found between IQ growth and other possible factors, i.e. gender, age of CI, use of hearing aid, genotype, implant device type, inner ear malformation and CAP growth (p > 0.05). Our study suggests that CI potentially improves the intelligence development in deaf children. Speech performance growth is significantly correlated with IQ growth of CI children. Deaf children accepted CI before 6 years can achieve a satisfying and undifferentiated short-term (12 months) development of intelligence. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

The Structure of Social Exchange in Self-Help Support Groups: Development of a Measure

Brown, Louis D.; Tang, Xiaohui; Hollman, Ruth L.

2014-01-01

Self-help support groups are indigenous community resources designed to help people manage a variety of personal challenges, from alcohol abuse to xeroderma pigmentosum. The social exchanges that occur during group meetings are central to understanding how people benefit from participation. This paper examines the different types of social exchange behaviors that occur during meetings, using two studies to develop empirically distinct scales that reliably measure theoretically important types of exchange. Resource theory informed the initial measurement development efforts. Exploratory factor analyses from the first study led to revisions in the factor structure of the social exchange scales. The revised measure captured the exchange of emotional support, experiential information, humor, unwanted behaviors, and exchanges outside meetings. Confirmatory factor analyses from a follow-up study with a different sample of self-help support groups provided good model fit, suggesting the revised structure accurately represented the data. Further, the scales demonstrated good convergent and discriminant validity with related constructs. Future research can use the scales to identify aspects of social exchange that are most important in improving health outcomes among self-help support group participants. Groups can use the scales in practice to celebrate strengths and address weaknesses in their social exchange dynamics. PMID:24398622

Background This article describes the validation of an instrument to measure work group climate in public health organizations in developing countries. The instrument, the Work Group Climate Assessment Tool (WCA), was applied in Brazil, Mozambique, and Guinea to assess the intermediate outcomes of a program to develop leadership for performance improvement. Data were collected from 305 individuals in 42 work groups, who completed a self-administered questionnaire. Methods The WCA was initially validated using Cronbach's alpha reliability coefficient and exploratory factor analysis. This article presents the results of a second validation study to refine the initial analyses to account for nested data, to provide item-level psychometrics, and to establish construct validity. Analyses included eigenvalue decomposition analysis, confirmatory factor analysis, and validity and reliability analyses. Results This study confirmed the validity and reliability of the WCA across work groups with different demographic characteristics (gender, education, management level, and geographical location). The study showed that there is agreement between the theoretical construct of work climate and the items in the WCA tool across different populations. The WCA captures a single perception of climate rather than individual sub-scales of clarity, support, and challenge. Conclusion The WCA is useful for comparing the climates of different work groups, tracking the changes in climate in a single work group over time, or examining differences among individuals' perceptions of their work group climate. Application of the WCA before and after a leadership development process can help work groups hold a discussion about current climate and select a target for improvement. The WCA provides work groups with a tool to take ownership of their own group climate through a process that is simple and objective and that protects individual confidentiality. PMID:16223447

To study the effect of ketogenic diet (KD) on neurobehavioral development, emotional and social behaviors, and life ability in children with global developmental delay (GDD). A prospective case-control study was performed for hospitalized children with GDD, who were randomly divided into KD treatment group (n=40) and conventional treatment group (n=37). The children in both groups were given comprehensive rehabilitation training, and those in the KD treatment group were given modified Atkins diet in addition to the comprehensive rehabilitation training. The children in both groups were assessed with the Gesell Developmental Scale, Chinese version of Urban Infant-Toddler Social and Emotional Assessment (CITSEA)/Achenbach Child Behavior Checklist (CBCL), and Infants-Junior High School Students' Social Life Abilities Scale (S-M scale) before treatment and after 3, 6, and 9 months of treatment. The two groups were compared in terms of the improvements in neurobehavioral development, emotional and social behaviors, and social life ability. After 3, 6, and 9 months of treatment, the KD treatment group had significantly greater improvements in the scores of the adaptive, fine motor, and language quotients of the Gesell Developmental Scale compared with the conventional treatment group (P<0.05); the KD treatment group had significantly greater improvements in CITSEA/CBCL scores than the conventional treatment group (P<0.05). The KD treatment group had a greater improvement in the score of the S-M scale after 9 months of treatment (P<0.05). During the KD treatment, 6 children experienced diarrhea and 1 experienced mild urinary stones. KD can improve the neurobehavioral development and behavioral and emotional behaviors in children with GDD, and it has few adverse effects.

Teachers are at risk of developing voice disorders, but longitudinal studies on voice problems among teachers are lacking. The aim of this randomized trial was to investigate long-term effects of voice education for teacher students with mild voice problems. In addition, vocal health was examined prospectively in a group of students without voice problems. First-semester students answered three questionnaires: one about background factors, one about voice symptoms (Screen6), and the Voice Handicap Index. Students with voice problems according to the questionnaire results were randomized to a voice training group or a control group. At follow-up in the sixth semester, all students answered Screen6 again together with four questions about factors that could have affected vocal health during their teacher education. The training group and the control group also answered the Voice Handicap Index a second time. At follow-up, 400 students remained in the study: 27 in the training group, 54 in the control group, and 319 without voice problems at baseline. Voice problems had decreased somewhat more in the training group than in the control group, but the difference was not statistically significant (P = 0.1). However, subgroup analyses showed significantly larger improvement among the students in the group with complete participation in the training program compared with the group with incomplete participation. Of the 319 students without voice problems at baseline, 14% had developed voice problems. Voice problems often develop in teacher students. Despite extensive dropout, our results support the hypothesis that voice education for teacher students has a preventive effect. Copyright © 2016 The Voice Foundation. Published by Elsevier Inc.

Environmental health hazard assessments are routinely relied upon for public health decision-making. The evidence base used in these assessments is typically developed from a collection of diverse sources of information of varying quality. It is critical that literature-based evaluations consider the credibility of individual studies used to reach conclusions through consistent, transparent and accepted methods. Systematic review procedures address study credibility by assessing internal validity or “risk of bias” — the assessment of whether the design and conduct of a study compromised the credibility of the link between exposure/intervention and outcome. This paper describes the commonalities and differences in risk-of-bias methods developed or used by five groups that conduct or provide methodological input for performing environmental health hazard assessments: the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) Working Group, the Navigation Guide, the National Toxicology Program’s (NTP) Office of Health Assessment and Translation (OHAT) and Office of the Report on Carcinogens (ORoC), and the Integrated Risk Information System of the U.S. Environmental Protection Agency (EPA-IRIS). Each of these groups have been developing and applying rigorous assessment methods for integrating across a heterogeneous collection of human and animal studies to inform conclusions on potential environmental health hazards. There is substantial consistency across the groups in the consideration of risk-of-bias issues or “domains” for assessing observational human studies. There is a similar overlap in terms of domains addressed for animal studies; however, the groups differ in the relative emphasis placed on different aspects of risk of bias. Future directions for the continued harmonization and improvement of these methods are also discussed. PMID:26857180

Chronic illness is of concern to health care systems globally. Although a significant evidence base supports the concept of nurse-led interventions, less data is available to address unique features of health care systems in the developing world. The purpose of this study aimed to undertake preliminary testing of an intervention of nurse-led community care program, the Network Collaborative Action Plan (N-CAP), to assess the impact on disease severity and patient satisfaction. A quasi-experimental study, using historical controls, evaluated a collaborative nurse-led intervention to promote coordination and continuity of care for patients with chronic illness. Participants, diagnosed with chronic obstructive lung disease (COPD), coronary heart disease (CHD) and chronic heart failure (CHF) were recruited. Prospective consecutive patient meeting the study criteria (n=47) were assigned into the control group and following development and implementation of the intervention eligible consenting patients were enrolled in the experimental group (n=44). Participants in the experimental group had significantly tower scores on severity of disease measurements during the third week (F = 4.61, p = 0.035) and the eighth week hospital (F = 4.30, p = .041) following hospital discharge than those in the control group. Participants in the experimental group expressed significantly higher scores on satisfaction with community care than those in the control group. A nurse-led, collaboratively developed program has potential to improve satisfaction and decrease symptom development in people with chronic illnesses in Thailand.

The clinical course and prognostic factors of HER2-positive breast cancer patients with brain metastases are not well known because of the relatively small population. The aim of this study was to determine prognostic factors associated with HER2-positive patients who develop brain metastases. This retrospective study assessed the largest dataset to date of 432 HER2-positive patients who were diagnosed with brain metastases from 24 institutions of the Japan Clinical Oncology Group, Breast Cancer Study Group. The median age of the 432 patients was 54 years (range, 20-86 years). Of the patients, 162 patients (37.5 %) had ER-positive/HER2-positive (ER+HER2+) breast cancer, and 270 (62.5 %) had ER-negative/HER2-positive (ER-HER2+) breast cancer. The median brain metastasis-free survival period from primary breast cancer was 33.5 months in both groups. The median survival after developing brain metastasis was 16.5 and 11.5 months in the ER+HER2+ and ER-HER2+ groups, respectively, (p = 0.117). Patients with >3 brain metastases had significantly shorter overall survival in both ER+HER2+ (p < 0.001) and ER-HER2+ (p = 0.018) groups. Treatment with trastuzumab before developing brain metastases was not associated with survival duration after developing brain metastases (p = 0.571). However, patients treated with both trastuzumab and lapatinib after developing metastasis had significantly longer survival than patients treated with trastuzumab alone, lapatinib alone, or no HER2-targeting agent (p < 0.001). For HER2-positive patients with brain metastases, regardless of the use of trastuzumab before developing brain metastasis, treatment with both trastuzumab and lapatinib might improve survival.

Progress in the Development of a Prototype Reuse Enablement System

2008-12-01

An important part of promoting software reuse is to ensure that reusable software assets are readily available to the software developers who want to use them. Through dialogs with the community, the NASA Earth Science Data Systems Software Reuse Working Group has learned that the lack of a centralized, domain- specific software repository or catalog system addressing the needs of the Earth science community is a major barrier to software reuse within the community. The Working Group has proposed the creation of such a reuse enablement system, which would provide capabilities for contributing and obtaining reusable software, to remove this barrier. The Working Group has recommended the development of a Reuse Enablement System to NASA and has performed a trade study to review systems with similar capabilities and to identify potential platforms for the proposed system. This was followed by an architecture study to determine an expeditious and cost-effective solution for this system. A number of software packages and systems were examined through both creating prototypes and examining existing systems that use the same software packages and systems. Based on the results of the architecture study, the Working Group developed a prototype of the proposed system using the recommended software package, through an iterative process of identifying needed capabilities and improving the system to provide those capabilities. Policies for the operation and maintenance of the system are being established for the system, and the identification of system policies also has contributed to the development process. Additionally, a test plan is being developed for formal testing of the prototype, to ensure that it meets all of the requirements previously developed by the Working Group. This poster summarizes the results of our work to date, focusing on the most recent activities.

Practice development 'without walls' and the quandary of corporate practice.

PubMed

Graham, Iain; Fielding, Carol; Rooke, Debbie; Keen, Steven

2006-08-01

The context of this study is a group of clinical nurse specialists from across a Trust seeking accreditation as a practice development unit. The university was asked to facilitate the accreditation process via 11 2-hour learning sessions (including a one-hour focus group). During initial discussions between the university and practice development unit, the overarching research question for this study was set as: 'what are the main roles and responsibilities of clinical nurse specialists?' Although there is no known study of a practice development unit based beyond a ward or speciality, the central tenet of the practice development unit literature is that units must demonstrate their worth if they are to survive and harness senior management support in doing so. Data gleaned from the transcribed audio tape-recordings of the learning sessions were studied at least three times to ensure transcription accuracy and produce detailed charts. Ethical approval was granted by the appropriate Local Research Ethics Committee and written informed consent obtained from clinical nurse specialists. The study lasted 30 months and ended in October 2004. The four crucial statements that give meaning to specialist practice are: quality care giver; expert; information giver and initiator of change. Further analysis reveals the area of corporate and political practice as being missing from this and other lists of clinical nurse specialist attributes found in the literature. Clinical nurse specialists characterize their relationship with the Trust in terms of dichotomy--differing agendas and perceptions of value. The specialist role requires professional development in the areas of corporate and political acumen and professional business management. While the findings of this study relate to one Trust and a group of 16 clinical nurse specialists, with careful application they may be transferable to other settings and groups of senior nurses.

2014-06-01

Appropriate schemes for classification of freshwater phytoplankton are prerequisites and important tools for revealing phytoplanktonic succession and studying freshwater ecosystems. An alternative approach, functional group of freshwater phytoplankton, has been proposed and developed due to the deficiencies of Linnaean and molecular identification in ecological applications. The functional group of phytoplankton is a classification scheme based on autoecology. In this study, the theoretical basis and classification criterion of functional group (FG), morpho-functional group (MFG) and morphology-based functional group (MBFG) were summarized, as well as their merits and demerits. FG was considered as the optimal classification approach for the aquatic ecology research and aquatic environment evaluation. The application status of FG was introduced, with the evaluation standards and problems of two approaches to assess water quality on the basis of FG, index methods of Q and QR, being briefly discussed.

Abstract After a brief introduction about the factors that are involved in science development, and world and Brazilian evolutionary genetics, the studies developed in Porto Alegre in this area were reviewed. Four periods in the development of this group were distinguished: (a) Origins and first expansion (1949-1961); (b) Second expansion (1962-1988); (c) Third expansion (1989-2001); and (d) The last 15 years (2002-present). The international Porto Alegre Biological Evolution Workshops (PABEWs), with five biannual events from 2007 o 2015, were also mentioned. The final message stressed the importance of the maintenance of this and other Brazilian groups of research through adequate finance and recognition. PMID:29583152

Heredity plays an important role in keratoconus (KC). Consanguineous marriage (CM) can affect the transmission of recessively inherited conditions. We aimed to investigate the role of consanguineous marriage in the development of KC. This study included two groups: the first group comprised 415 patients who underwent surgery for KC for the first time at Khalili University Hospital (Shiraz, Iran), between 2010 and 2014; the second group comprised 415 healthy individuals who served as age- and sex-matched controls for the patient group. All study subjects were from the Fars province in Iran. CM type was evaluated by a standard checklist in both groups. The mean inbreeding coefficient (α) was evaluated and compared between the two groups. The percentage of parental first-cousin marriages was 35.4% in the patient group and 18.3% in the control group. The mean inbreeding coefficient (α) was 0.0291 in the patient group and 0.0135 in the control group. Patients with KC had a significantly higher mean inbreeding coefficient (α) than controls (T = 8, df = 828, P < 0.001). Our study suggests that CM can play a role in the pathogenesis of KC. As this disease is among the most frequent ocular disorders in our country, CM should be considered by health care systems within their screening programs. PMID:29644240

The present study evaluated the effectiveness of sildenafil citrate (SC) to improve placental and fetal growth in a diet-induced rabbit model of intrauterine growth restriction (IUGR). Pregnant rabbits were fed either ad libitum (Group C) or restricted to 50% of dietary requirements (Group R) or restricted and treated with SC (Group SC). The treatment with SC improved placental development by increasing vascularity and vessel hypertrophy in the decidua. The assessment of feto-placental haemodynamics showed higher resistance and pulsatility indices at the middle cerebral artery (MCA) in fetuses treated with SC when compared with Group R, which had increased systolic peak and time-averaged mean velocities at the MCA. Furthermore, fetuses in the SC group had significantly higher biparietal and thoracic diameters and longer crown-rump lengths than fetuses in Group R. Hence, the SC group had a reduced IUGR rate and a higher kit size at birth compared with Group R. In conclusion, SC may provide potential benefits in pregnancies with placental insufficiency and IUGR, partially counteracting the negative effects of food restriction on placental development and fetal growth. However, the present study also found evidence of a possible blood overflow in the brain that warrants further investigation.

[RATE OF PHYSICAL DEVELOPMENT IN BOYS AGED 10-11 YEARS AND THE EFFECTS OF TRAINING LOADS DURING A 12-MONTH SOCCER PROGRAM].

The aim of the study was to evaluate the rate of physical development in prepubertal boys in response to training at different loads. The study involved two groups of soccer players, experimental groups E1 (n = 26, age 10.4 ± 0.6 years) and E2 (n = 27, age 10.3 ± 0.8 years) who were involved in a 12-month soccer training program, and a control group (C) of age-matched untrained boys (n = 22). The training protocol of E1 involved a greater share of coordination-based exercises, in E2 more focus was placed on conditioning fitness and strength. Body height, mass, fat percentage, and body mass index were measured pre-, peri-, and post-training. Chronological and developmental age were used to calculate a Biological State Maturity Index (BSMI). Between-group differences were observed in body fat percentage, which was higher in the control group by 6.8% at post-training compared with E1 (p < 0.05). E1 showed the most congruence between chronological and developmental age. Developmental age was most retarded in E2 by an average of 4.3 months. Greatest between-group differences were observed in E1 and the control group for the BSMI of body height (49.9%) at pre-training. BSMI of height and mass in the control group were different (p < 0.01) from both experimental groups at pre-, peri-, and post-training. 1. The experimental soccer training programs were conducive to the physical development of boys aged 10-11 years as evidenced by the absence of disturbances in the range of observed variables characterizing the body built and biological development. 2. Body mass index did not accurately reflect changes in body composition. A more detailed analysis of body composition is required in the recruitment and selection of young soccer players in order to better control the effects of training and diet. 3. The adopted BSMI measure indicated a delay in growth according to developmental age norms in the entire sample. However, the accelerated physical development in E1 during the study duration may be indicative of the stimulative effect of this group's training program and the adopted training load on physical development.

Background Group therapy and education and support sessions are used within health care across a range of disciplines such as chronic disease self-management and psychotherapy interventions. However, there are barriers that constrain group attendance, such as mobility, time, and distance. Using videoconferencing may overcome known barriers and improve the accessibility of group-based interventions. Objective The aim of this study was to review the literature to determine the feasibility, acceptability, effectiveness, and implementation of health professional–led group videoconferencing to provide education or social support or both, into the home setting. Methods Electronic databases were searched using predefined search terms for primary interventions for patient education and/or social support. The quality of studies was assessed using the Mixed Methods Appraisal Tool. We developed an analysis framework using hierarchical terms feasibility, acceptability, effectiveness, and implementation, which were informed by subheadings. Results Of the 1634 records identified, 17 were included in this review. Home-based groups by videoconferencing are feasible even for those with limited digital literacy. Overall acceptability was high with access from the home highly valued and little concern of privacy issues. Some participants reported preferring face-to-face groups. Good information technology (IT) support and training is required for facilitators and participants. Communication can be adapted for the Web environment and would be enhanced by clear communication strategies and protocols. A range of improved outcomes were reported but because of the heterogeneity of studies, comparison of these across studies was not possible. There was a trend for improvement in mental health outcomes. Benefits highlighted in the qualitative data included engaging with others with similar problems; improved accessibility to groups; and development of health knowledge, insights, and skills. Videoconference groups were able to replicate group processes such as bonding and cohesiveness. Similar outcomes were reported for those comparing face-to-face groups and videoconference groups. Conclusions Groups delivered by videoconference are feasible and potentially can improve the accessibility of group interventions. This may be particularly useful for those who live in rural areas, have limited mobility, are socially isolated, or fear meeting new people. Outcomes are similar to in-person groups, but future research on facilitation process in videoconferencing-mediated groups and large-scale studies are required to develop the evidence base.

Many informatics studies use content analysis to generate functional requirements for system development. Explication of this translational process from qualitative data to functional requirements can strengthen the understanding and scientific rigor when applying content analysis in informatics studies. To describe a user-centered approach transforming emergent themes derived from focus group data into functional requirements for informatics solutions and to illustrate these methods to the development of an antibiotic clinical decision support system (CDS). THE APPROACH CONSISTED OF FIVE STEPS: 1) identify unmet therapeutic planning information needs via Focus Group Study-I, 2) develop a coding framework of therapeutic planning themes to refine the domain scope to antibiotic therapeutic planning, 3) identify functional requirements of an antibiotic CDS system via Focus Group Study-II, 4) discover informatics solutions and functional requirements from coded data, and 5) determine the types of information needed to support the antibiotic CDS system and link with the identified informatics solutions and functional requirements. The coding framework for Focus Group Study-I revealed unmet therapeutic planning needs. Twelve subthemes emerged and were clustered into four themes; analysis indicated a need for an antibiotic CDS intervention. Focus Group Study-II included five types of information needs. Comments from the Barrier/Challenge to information access and Function/Feature themes produced three informatics solutions and 13 functional requirements of an antibiotic CDS system. Comments from the Patient, Institution, and Domain themes generated required data elements for each informatics solution. This study presents one example explicating content analysis of focus group data and the analysis process to functional requirements from narrative data. Illustration of this 5-step method was used to develop an antibiotic CDS system, resolving unmet antibiotic prescribing needs. As a reusable approach, these techniques can be refined and applied to resolve unmet information needs with informatics interventions in additional domains.

Widespread use of heavy metal lead (Pb) for various commercial purposes has resulted in the environmental contamination caused by this metal. The studies have shown a definite relationship between low level lead exposure during early brain development and deficit in children's cognitive functions. This study investigated the passive avoidance learning and spatial learning in male rat pups exposed to lead through their mothers during specific periods of early brain development. Experimental male rats were divided into 5 groups: i) the normal control group (NC) (N = 12) consisted of rat offspring born to mothers who were given normal drinking water throughout gestation and lactation, ii) the pre-gestation lead exposed group (PG) (N = 12) consisted of rat offspring, mothers of these rats had been exposed to 0.2% lead acetate in the drinking water for 1 month before conception, iii) the gestation lead exposed group (G) (N = 12) contained rat offspring born to mothers who had been exposed to 0.2% lead acetate in the drinking water throughout gestation, iv) the lactation lead exposed group (L) (N = 12) had rat offspring, mothers of these rats exposed to 0.2% lead acetate in the drinking water throughout lactation and v) the gestation and lactation lead exposed group (GL) (N = 12) contained rat offspring, mothers of these rats were exposed to 0.2% lead acetate throughout gestation and lactation. The study found deficit in passive avoidance learning in the G, L and GL groups of rats. Impairment in spatial learning was found in the PG, G, L and GL groups of rats. Interestingly, the study found that gestation period only and lactation period only lead exposure was sufficient to cause deficit in learning and memory in rats. The extent of memory impairment in the L group of rats was comparable with the GL group of rats. So it can be said that postnatal period of brain development is more sensitive to neurotoxicity compared to prenatal exposure.

To estimate prevalence of exposure to environmental tobacco smoke and other environmental toxins in dogs with primary lung tumours and to analyse association between exposure and lung tumour development. In this case-control study, an owner survey was developed to collect data on patient characteristics, general health care and environmental exposures. Dogs diagnosed with primary lung carcinomas formed the Case group. Dogs diagnosed with mast cell tumours served as Control Group 1 and dogs diagnosed with neurologic disease served as Control Group 2. Associations between diagnosis of primary lung tumour and patient and environmental exposure variables were analysed using bivariate and multivariate statistical methods. A total of 1178 owner surveys were mailed and 470 surveys were returned and included in statistical analysis, including 135 Cases, 169 dogs in Control Group 1 and 166 dogs in Control Group 2. An association between exposure to second-hand smoke and prevalence of primary lung cancer was not identified in this study. Second-hand smoke is associated with primary lung cancer in people but a definitive association has not been found in dogs. The results of this study suggest that tobacco smoke exposure may not be associated with primary lung cancer development in dogs but study limitations may have precluded detection of an association. © 2017 British Small Animal Veterinary Association.

Development of a novel mouse model of hepatocellular carcinoma with nonalcoholic steatohepatitis using a high-fat, choline-deficient diet and intraperitoneal injection of diethylnitrosamine.

The incidence of hepatocellular carcinoma with nonalcoholic steatohepatitis is increasing, and its clinicopathological features are well established. Several animal models of nonalcoholic steatohepatitis have been developed to facilitate its study; however, few fully recapitulate all its clinical features, which include insulin resistance, inflammation, fibrosis, and carcinogenesis. Moreover, these models require a relatively long time to produce hepatocellular carcinoma reliably. The aim of this study was to develop a mouse model of hepatocellular carcinoma with nonalcoholic steatohepatitis that develops quickly and reflects all clinically relevant features. Three-week-old C57BL/6J male mice were fed either a standard diet (MF) or a choline-deficient, high-fat diet (HFCD). The mice in the MF + diethylnitrosamine (DEN) and HFCD + DEN groups received a one-time intraperitoneal injection of DEN at the start of the respective feeding protocols. The mice in the HFCD and HFCD + DEN groups developed obesity early in the experiment and insulin resistance after 12 weeks. Triglyceride levels peaked at 8 weeks for all four groups and decreased thereafter. Alanine aminotransferase levels increased every 4 weeks, with the HFCD and HFCD + DEN groups showing remarkably high levels; the HFCD + DEN group presented the highest incidence of nonalcoholic steatohepatitis. The levels of fibrosis and steatosis varied, but they tended to increase every 4 weeks in the HFCD and HFCD + DEN groups. Computed tomography scans indicated that all the HFCD + DEN mice developed hepatic tumors from 20 weeks, some of which were glutamine synthetase-positive. The nonalcoholic steatohepatitis-hepatocellular carcinoma model we describe here is simple to establish, results in rapid tumor formation, and recapitulates most of the key features of nonalcoholic steatohepatitis. It could therefore facilitate further studies of the development, oncogenic potential, diagnosis, and treatment of this condition.

The study was designed to determine if application of a self-adherent silicone border foam dressing would reduce pressure ulcer incidence when compared to standard preventive interventions among patients managed in a cardiac surgery intensive care unit (CSICU). One hundred consecutive patients in the CSICU at Virginia Commonwealth University Medical Center in Richmond participated in the study. Fifteen were subsequently excluded due to incomplete data or failure to remain in the CSICU for at least 48 hours. Of the 100 subjects consecutively enrolled, 56 subjects were assigned to the intervention group with attrition of 6 subjects (6/56), and 39 were assigned to the standard care comparison group with attrition of 4 subjects (4/39). Five study forms were lost and the group assignment of those subjects is unknown. Patients admitted to the CSICU were assigned to either standard treatment or an intervention group consisting of standard preventive care plus application of the silicone border foam dressing. The assignment of subjects to these groups was done in a nonrandom manner, via prestudy room designation (7 intervention rooms/7 standard practice rooms) and room availability on call from the operating room. The charge nurse and bed management staff were unaware of room designation, and staff did not know which group the subjects were assigned to until they admitted the patient and opened the bedside chart that indicated group assignment. Twenty-one covariates were compared between the 2 groups. A Cox proportional hazards model was computed to compare the hazard (risk per unit time) of developing a pressure ulcer between these groups. Propensity score covariate adjustment was performed to adjust for any imbalance between the groups. Nine pressure ulcers developed during the course of the study. Eight pressure ulcers developed in 4 out of 35 patients who received standard preventive care; 5 were classified as suspected deep tissue injuries and 3 were classified as stage II pressure ulcers. One pressure ulcer developed in 1 out of 50 patients in the intervention group; it was classified as suspected deep tissue injury. No statistically significant difference in any covariate was found between the groups (all P > .058). The group that received standard care had a hazard ratio of 3.6 in relation to the intervention group, but this difference was not statistically significant (P = .3). Pressure ulcer incidence was lower than anticipated over the study period for both groups. No statistically significant difference in pressure ulcer incidence between the intervention and control groups was found. A randomized controlled trial based on a power analysis is needed to more precisely determine the efficacy of a silicone border foam dressing for prevention of pressure ulcers in the intensive care unit.

This study aimed to develop and cross-validate prediction equations for estimating appendicular skeletal muscle mass (ASM) and to examine the relationship between sarcopenia defined by the prediction equations and risk factors for cardiovascular diseases (CVD) or osteoporosis in Japanese men and women. Subjects were healthy men and women aged 20-90 years, who were randomly allocated to the following two groups: the development group (D group; 257 men, 913 women) and the cross-validation group (V group; 119 men, 112 women). To develop prediction equations, stepwise multiple regression analyses were performed on data obtained from the D group, using ASM measured by dual-energy X-ray absorptiometry (DXA) as a dependent variable and five easily obtainable measures (age, height, weight, waist circumference, and handgrip strength) as independent variables. When the prediction equations for ASM estimation were applied to the V group, a significant correlation was found between DXA-measured ASM and predicted ASM in both men and women (R 2  = 0.81 and R 2  = 0.72). Our prediction equations had higher R 2 values compared to previously developed equations (R 2  = 0.75-0.59 and R 2  = 0.69-0.40) in both men and women. Moreover, sarcopenia defined by predicted ASM was related to risk factors for osteoporosis and CVD, as well as sarcopenia defined by DXA-measured ASM. In this study, novel prediction equations were developed and cross-validated in Japanese men and women. Our analyses validated the clinical significance of these prediction equations and showed that previously reported equations were not applicable in a Japanese population.

Writing in science: Influences of professional development on teachers' beliefs, practices, and student performance

NASA Astrophysics Data System (ADS)

Fulton, Lori

Science education reform calls for learners to be engaged in hand-on, minds-on activities related to science. As a part of this reform effort, learners are encouraged to use writing as a means of documenting their work and developing their understandings. This qualitative case study employed the Conceptual Change Perspective and Sociocultural Perspective to examine the impact on three elementary teachers' beliefs, practices, and student outcomes, as they relate to science notebooks, based on their participation in a professional study group. Data sources included teacher and student interviews, video of the study group meetings, video of classroom lessons, and student work in the form of science notebooks and pre- and posttests. Results show that the study group discussions focused on the science notebook as a tool, the teacher's role, the students' struggle to write, and the content of the notebook. Individual cases were developed and then a cross-case analysis was conducted. Results of this analysis suggest that the longer a teacher is involved in a study group, the greater the impact on her beliefs and practices, which resulted in students being able to define a purpose for the notebook, having a higher percentage of the parts of a conclusion within their notebooks, and demonstrating an understanding of the scientific content. Based on the analysis, a substantive theory on the development of insightful implementation of science notebooks was developed. This study has implications for both the elementary classroom and teacher education programs in helping teachers learn reform-based practices that facilitate student learning. Finally, suggestions for future research are considered.

2014-01-01

In a non-matched case-control study using data from two large national cohort studies, we investigated whether indicators of child health and development up to 7 years of age differ between children conceived using assisted reproductive technology (ART), children born after sub-fertility (more than 24 months of trying for conception) and other children. Information on ART use/sub-fertility was available for 23,649 children. There were 227 cases (children conceived through ART) and two control groups: 783 children born to sub-fertile couples, and 22,639 children born to couples with no fertility issues. In models adjusted for social and demographic factors there were significant differences between groups in rate of hospital admissions before the children were 9 months old (P=0.029), with the ART group showing higher rates of hospital admission than the no fertility issues control group, the sub-fertile control group being intermediate between the two. Children born after ART had comparable health and development beyond 9 months of age to their naturally conceived peers. This applied to the whole sample and to a sub-sample of children from deprived neighborhoods. PMID:24711911

Quantitative Analysis Of User Interfaces For Large Electronic Home Appliances And Mobile Devices Based On Lifestyle Categorization Of Older Users.

PubMed

Shin, Wonkyoung; Park, Minyong

2017-01-01

Background/Study Context: The increasing longevity and health of older users as well as aging populations has created the need to develop senior-oriented product interfaces. This study aims to find user interface (UI) priorities according to older user groups based on their lifestyle and develop quality of UI (QUI) models for large electronic home appliances and mobile products. A segmentation table designed to show how older users can be categorized was created through a review of the literature to survey 252 subjects with a questionnaire. Factor analysis was performed to extract six preliminary lifestyle factors, which were then used for subsequent cluster analysis. The analysis resulted in four groups. Cross-analysis was carried out to investigate which characteristics were included in the groups. Analysis of variance was then applied to investigate the differences in the UI priorities among the user groups for various electronic devices. Finally, QUI models were developed and applied to those electronic devices. Differences in UI priorities were found according to the four lifestyles ("money-oriented," "innovation-oriented," "stability- and simplicity-oriented," and "innovation- and intellectual-oriented"). Twelve QUI models were developed for four different lifestyle groups associated with different products. Three washers and three smartphones were used as an example for testing the QUI models. The UI differences of the older user groups by the segmentation in this study using several key (i.e., demographic, socioeconomic, and physical-cognitive) variables are distinct from earlier studies made by a single variable. The differences in responses clearly indicate the benefits of integrating various factors of older users, rather than single variable, in order to design and develop more innovative and better consumer products in the future. The results of this study showed that older users with a potentially high buying power in the future are likely to have higher satisfaction when selecting products customized for their lifestyle. Designers could also use the results of UI evaluation for older users based on their lifestyle before developing products through QUI modeling. This approach would save time and costs.

2015-01-01

The transgenerational transmission of mental disorders is one of the most prominent risk factors for the development of psychological disorders. Children of mentally ill parents are a vulnerable high risk group with overall impaired development and high rates of psychological disorders.

We translated the evidence based Family Talk Intervention by Beardslee (2009) and adapted it for groups. First results of this pilot study are presented. This investigation evaluates a preventive group intervention for children of mentally ill parents. In a quasi-experimental design three groups are compared: an intervention group (Family Talk Intervention group: n = 28), a Wait Control group (n = 9), and a control group of healthy children (n = 40). Mean age of children was 10.41 years and parental disorders were mostly depressive/affective disorders (n = 30), but a small number also presented with Attention-Deficit/Hyperactivity Disorder (n = 7). Children of mentally ill parents showed higher rates of internalizing/externalizing disorders before and after the intervention compared to children of parents with no disorders. Post intervention children's knowledge on mental disorders was significantly enhanced in the Family Talk Intervention group compared to the Wait Control group and the healthy control group. Parental ratings of externalizing symptoms in the children were reduced to normal levels after the intervention in the Family Talk Intervention group, but not in the Wait Control group. This pilot study of a group intervention for children of mentally ill parents highlights the importance of psycho-education on parental mental disorders for children. Long-term effects of children's enhanced knowledge about parental psychopathology need to be explored in future studies.

Objective: The transgenerational transmission of mental disorders is one of the most prominent risk factors for the development of psychological disorders. Children of mentally ill parents are a vulnerable high risk group with overall impaired development and high rates of psychological disorders. To date there are only a few evidence based intervention programs for this group overall and hardly any in Germany. We translated the evidence based Family Talk Intervention by Beardslee (2009) and adapted it for groups. First results of this pilot study are presented. Method: This investigation evaluates a preventive group intervention for children of mentally ill parents. In a quasi-experimental design three groups are compared: an intervention group (Family Talk Intervention group: n = 28), a Wait Control group (n = 9), and a control group of healthy children (n = 40). Mean age of children was 10.41 years and parental disorders were mostly depressive/affective disorders (n = 30), but a small number also presented with Attention-Deficit/Hyperactivity Disorder (n = 7). Results: Children of mentally ill parents showed higher rates of internalizing/externalizing disorders before and after the intervention compared to children of parents with no disorders. Post intervention children's knowledge on mental disorders was significantly enhanced in the Family Talk Intervention group compared to the Wait Control group and the healthy control group. Parental ratings of externalizing symptoms in the children were reduced to normal levels after the intervention in the Family Talk Intervention group, but not in the Wait Control group.

While teachers have traditionally used the interesting objects to increase student attention in the classroom, evidence supporting the effectiveness of this method is lacking. The present study investigated the influence of different stimulus attributes for typical developing students and for students with attention deficit/hyperactivity disorder (ADHD) and dyslexia. Thirty children with ADHD, 30 children with dyslexia, and 30 typical developing students were tested using a measuring tool that was constructed by the authors to assess their sustained attention and selective attention on the geometric-figure assessment and the interesting-figure assessment. The geometric-figure assessment included a square, circle, trapezium, and triangle; and the interesting-figure assessment included a house, cat, hand, and tree. While the typical developing group showed better selective attention on the geometric-figure assessment, there was no difference between the dyslexic group and the ADHD group with respect to selective attention. Furthermore, the typical developing and dyslexic groups did not differ in the geometric-figure assessment in sustained attention and were both better in this area than the ADHD group. In the interesting-figure assessment, the typical developing and dyslexic groups performed similarly in sustained attention, but selective attention of the dyslexic group improved more than the ADHD group, similar to the typical developing group. Both selective attention of the dyslexic group and sustained attention of the ADHD group showed positive significant differences in the interesting-figure assessment, but sustained attention of the dyslexic group and selective attention of the ADHD group showed little difference in the interesting-figure assessment. Surprisingly, the typical developing group did not show any significant difference in the interesting-figure assessment, possibly because they had previously demonstrated a ceiling effect in the geometric-figure assessment.

The long-term effect of repetitive trauma by military parachuting on the lumbar spine is not well investigated. Therefore, the purpose of this study was to examine the development of lumbar degenerative changes during a 30-year follow-up in Japanese Ground Self Defense Forces (JGSDF) parachute infantry soldiers with normal lumbar radiographs at entry by comparison with those with non-parachute infantry soldiers. 79 non-parachutists and 65 parachutists were included for radiological examination and questionnaires for low back pain (LBP). All subjects were non-commissioned officers with similar socioeconomic status and life styles. The number of parachuting descent during the 30-year in the parachute group ranged from 208 to 630, with an average of 322. The mean age of the subjects was 18.3±0.5 years at entry and 48.5±0.3 years at follow-up. LBP had been experienced by 37% in the non-parachute group and 25% in the parachute group with no significant difference. The nature of their LBP was judged as mild. The prevalence rate of degenerative changes was similar in both groups. Disc space narrowing was detected 37 subjects (47%) in non-parachute group an 23 subjects (35%) in parachute group without significant difference. Vertebral osteophytes were detected in 52 subjects (67%) in non-parachute group and 47 subjects (72%) in parachute group without significant difference. This study did not identify any significant differences in the development of lumbar degenerative changes between the parachutists and non-parachutists over a 30-year follow-up, suggesting that military parachuting itself does not accelerate the development of intervertebral disc degeneration. Further studies are needed using large cohorts assessed by MRI as well as plain X-ray. Published by the BMJ Publishing Group Limited.

The current study examines the role of group interaction in a women's self-defense class. Study methods included individual interviews with women who had completed a college-based women-only self-defense course as well as supplemental observation of group behavior during a mock "attack" simulation class. The unique relationship that develops among women's self-defense classmates seems to improve overall learning and performance due to the group collaboration and vicarious experiences. Results demonstrated that women's self-defense courses offer participants a beneficial and supportive group atmosphere.

Framing and development of clinical skills in nursing students during their clinical practice is critical because this can shape their future caring skills. Professional caring empowers patients and contributes to their well-being and health. Education may enhance the capacity of nurses to be effective caring practitioners. Their study program encourages caring behavior in nursing students, consequently affecting their professional self-perception. The present study investigated the effect of an educational program on caring behavior and professional self-perception in nursing students using a controlled pre/post test study design. The study sample consisted of 50 nursing students undertaking their final year in 2010-2011. Subjects were randomly assigned to either an experimental or a control group. The study was conducted in two critical care units affiliated to the Ma'an and Queen Rania hospitals in the south of Jordan. The instruments utilized were the Caring Dimensions Inventory, Nursing Students Attitude Observational Checklist, and Professional Self-Concept of Nurses Instrument. The study findings favor the effect of the educational program because there was increased knowledge and understanding of caring theory and related concepts, a more holistic approach to care, enhanced caring practices, and improved self-perception in the study group compared with the control group during different periods of assessment. The study group showed significantly better caring perception in psychological, technical, and professional terms than the control group during different periods of assessment. There was a significant positive trend of overall professional self-perception for the study group compared with the control group. Nursing curricula should incorporate concepts and principles that guide students in developing caring, safe, competent, and professional behavior. Nursing students must seek educational opportunities to acquire knowledge for role preparation, to participate in knowledge generation, and for personal and professional development.

Impact of instructional Approaches to Teaching Elementary Science on Student Achievement

NASA Astrophysics Data System (ADS)

Kensinger, Seth H.

Strengthening our science education in the United States is essential to the future success of our country in the global marketplace. Immersing our elementary students with research-based quality science instruction is a critical component to build a strong foundation and motivate our students to become interested in science. The research for this study pertained to the type of elementary science instruction in correlation to academic achievement and gender. Through this study, the researcher answered the following questions: 1. What is the difference in achievement for elementary students who have been taught using one of the three science instructional approaches analyzed in this study: traditional science instruction, inquiry-based science instruction with little or no professional development and inquiry-based science instruction with high-quality professional development? 2. What is the difference in student achievement between inquiry-based instruction and non-inquiry based (traditional) instruction? 3. What is the difference in student achievement between inquiry with high quality professional development and inquiry with little or no professional development? 4. Do the three instructional approaches have differentiated effects across gender? The student achievement was measured using the 2010 fourth grade Pennsylvania System of School Assessment (PSSA) in Science. Data was collected from 15 elementary schools forming three main groupings of similar schools based on the results from the 2009 third grade PSSA in Mathematics and student and community demographics. In addition, five sub-group triads were formed to further analyze the data and each sub-group was composed of schools with matching demographic data. Each triad contained a school using a traditional approach to teaching science, a school utilizing an inquiry science approach with little or no professional development, and a school incorporating inquiry science instruction with high quality professional development. The five schools which provided its students with inquiry science and high quality professional development were Science Its Elementary (SIE) schools, as provided through a grant from the Pennsylvania Department of Education (PDE). The findings of the study indicated that there is evidence to suggest that elementary science achievement improves significantly when teachers have utilized inquiry instruction after receiving high-quality professional development. Specifically, the analysis of the whole group and the majority of the triad sub-groupings did result in a consistent trend to support science instruction utilizing inquiry with high-quality professional development compared to a traditional approach and an inquiry-based approach with little or no professional development. The gender analysis of this study focused on whether or not girls at the elementary school level would perform better than boys depending upon method of science instruction. The study revealed no relationship between approach to teaching science and achievement level based on gender. The whole group results and sub-group triads produced no significant findings for this part of the data analysis.

Vitamin D deficiency is effective in the development of acute rhinosinusitis and prolongation of inflammation by increasing inflammation in the sinonasal epithelium. Vitamin D deficiency is important in the development of bone barriers that prevent the complication of acute rhinosinusitis. Although Vitamin D levels may be a variable risk factor for various respiratory tract disorders, there are limited data on the role in sinonasal infections. Our aim was to investigate the association of 25-hydroxy-vitamin D (25OHD) levels with acute rhinosinusitis (ARS) and preseptal cellulitis complications. The type of the study is prospective case-control study. Fifteen patients in the pediatric age group with ARS-induced preseptal cellulitis complication were identified as Group 1, fifteen patients with ARS and without complication were identified as Group 2, and fifteen healthy volunteers were identified as Group 3. Serum 25OHD levels (nmol/l) were measured in addition to routine blood tests at the first admission of patients participating in the study. Statistical analysis was performed between groups. The ages of the cases ranged from 1 to 14 years with a mean of 5.62 ± 3.42 years. 55.6% of the cases (n = 25) were male; 44.4% (n = 20) were female children. As a result of classification in which vitamin D levels were compared with normal values, there was a statistically significant difference according to the presence of ARS (Group-1 and Group 2) and absence of ARS (Group-3) (p < 0.05). A statistically significant difference was also found between Group 1 and Group-3 (p < 0.05). Statistically significant difference between Group 1 and Group 3 suggests that lack of vitamin D predisposes to the complication of preseptal cellulitis. Comparison of Group 1 and 2 with Group 3 (normal subjects) suggests that Vit D has a protective effect against developing sinusitis.

Poly methyl methacrylate (PMMA) is the most widely used resist in electron beam lithography. This paper reports on a lithography and Raman spectroscopy study of development characteristics of PMMA in methanol, ethanol and isopropanol mixtures with water as developers. We have found that ethanol/water mixtures at a 4:1 volume ratio are an excellent, high resolution, non-toxic, developer for exposed PMMA. We also have found that the proper methodology to use so that contrast data can be compared to techniques used in polymer science is not to rinse the developed resist but to immediately dry with nitrogen. Our results show howmore » powerful simple lithographic techniques can be used to study ternary polymer solvent solutions when compared to other techniques used in the literature. Raman data shows that there both tightly bonded –OH groups and non-hydrogen bonded –OH groups play a role in the development of PMMA. Tightly hydrogen bonded –OH groups show pure Lorentzian Raman absorption only in the concentration ranges where ethanol/water and IPA/water mixtures are effective developers of PMMA. The impact of the understanding these interactions may open doors to a new developers of other electron beam resists that can reduce the toxicity of the waste stream.« less

The provision of essential nutrition-related content in US medical education has been deficient, despite efforts of the federal government and multiple professional organizations. Novel and efficient approaches are needed. A multi-department project was developed to create and pilot a computer-based compact disc instructional program covering the nutrition topics of oral rehydration therapy, calcium, and vitamins. Funded by an internal medical school grant, the content of the modules was written by Department of Pediatrics faculty. The modules were built by School of Informatics faculty and students, and were tested on a convenience sampling of 38 pediatric residents in a randomized controlled trial performed by a registered dietitian/School of Health and Rehabilitation Sciences Master's degree candidate. The modules were reviewed for content by the pediatric faculty principal investigator and the registered dietitian/School of Health and Rehabilitation Sciences graduate student. Residents completed a pretest of nutrition knowledge and attitude toward nutrition and Web-based instruction. Half the group was given three programs (oral rehydration therapy, calcium, and vitamins) on compact disc for study over 6 weeks. Both study and control groups completed a posttest. Pre- and postintervention objective test results in study vs control groups and attitudinal survey results before and after intervention in the study group were compared. The experimental group demonstrated significantly better posttrial objective test performance compared to the control group (P=0.0005). The study group tended toward improvement, whereas the control group performance declined substantially between pre- and posttests. Study group resident attitudes toward computer-based instruction improved. Use of these computer modules prompted almost half of the residents in the study group to independently pursue relevant nutrition-related information. This inexpensive, collaborative, multi-department effort to design a computer-based nutrition curriculum positively impacted both resident knowledge and attitudes.

The purpose of this study was to assess the effectiveness of a pain management education programme in improving the nurses' knowledge about, attitude towards and application of relaxation therapy. Pain of surgical patients has long been an existing problem of health care. Nursing staff need to be educated continuously to develop the professional ability of pain management. A quasi-study design with pre- and posttest and post- and posttest was used. Subjects were chosen from a medical centre in Taipei by convenience sampling. The total sample size of 81 was segregated into a study group of 42 and control group of 39 participants. The study group attended a seven-session pain management programme totalling 15 hours. The control group received no pain management training. Scaled measurements were taken on pain management knowledge and attitude and relaxation therapy practice. (1) Scores for pain management knowledge differed significantly between the two groups (F = 40.636, p = 0.001). (2) Attitudes towards pain management differed between the two groups (F = 8.328, p = 0.005) and remained stable over time (F = 1.603, p = 0.205). (3) Relaxation therapy practice differed significantly between the two groups, with the study group better than the control group (F = 4.006, p = 0.049). (4) Relaxation therapy was applied to nearly all (97.5%) of the patients cared for by study group nurses. All of the instructed patients performed this technique one to three times per day postsurgery. Continuing education can improve nurses' knowledge about, attitude towards and behaviour of pain management. Results of this study could be used to guide the development and implementation of continuing education programmes for nursing staff to enhance patients' care knowledge and skills.

Is there a relationship between fledge age and nest temperature in Western Bluebirds (Sialia mexicana)?

Phillips, Emily Marie; Thompson, Brent E.; Hathcock, Charles Dean

Extensive research has been done on temperature during bird incubation periods, but little has been done during nestling development, and to our knowledge, no studies have been done on Western Bluebird (Sialia mexicana) nestling development. In this study, dataloggers were used to monitor nest temperatures during the nestling development phase of Western Bluebirds to determine if there was a relationship between fledge age and temperature. The study was conducted in an existing nestbox network at Los Alamos National Laboratory and the surrounding area in north-central New Mexico. Based on the age of the nestlings at fledging, the nestboxes (n=65) weremore » split into three groups: early (16 and 17 days old, n=13), average (fledged at or between 18 and 20 days old, n=32), and late (21 days or older, n=20). The temperatures of the early and average (n=45) groups were not significantly different (p=0.32, W=3831000). There was a significant difference in the temperatures between the early and late groups (p=0.000, W=2965600). The early and average groups were then combined, tested against the late group, and were found to be significantly different (p=0.000, W=11315000). Analysis showed a difference within the first seven days post-hatch of 1.42°C between the early/average and late groupings. The results suggest that warmer nest temperatures during the nestling stage may influence the fledge date and may lead to faster fledging. There may be numerous explanations for this, such as a correlation with nestling development, and higher temperatures may allow for faster development. Brood size was non-significant and was not factored into the analysis. Future work should be directed in this area.« less

To obtain and study new data on the dynamics of the labor process and to develop a contraction-based index of labor progress. This study was carried out at the Delivery Room, Department of Obstetrics and Gynecology, Western Galilee Hospital, Nahariya, Israel, using a new device (Birth Track). We continuously monitored cervical dilatation (CD) and head descent (HD) in 30 nulliparaous women during active labor with (augmented group) and without (study group) oxytocin augmentation. This led to the development and validation of progress indices based on features extracted from continuous monitoring. There were no significant differences between the average of each parameter in the study and augmented groups, except for HD velocity. Average HD velocity was faster in the study group. Linear regression analyses demonstrated that head station (HS) amplitude and Toco amplitude were the best parameters for predicting HD velocity in both groups. In the study group, average HD velocity was also significantly related to Toco rate and contraction efficiency. In the augmented group, only a weak correlation with Toco rate was seen, and no correlation with contraction efficiency. With the assistance of the Birth Track device, we can obtain continuous data on the labor process and indices to estimate the labor progress process without the use of vaginal (manual) examination. © 2013 The Authors.

Musculoskeletal pain in more than one body region is common and a barrier to sustaining employment. We aimed to examine whether work characteristics predict the development of multi-site pain (MSP), and to determine differences in work-related predictors between age groups. This study is based on 5136 employees from the Study on Transitions in Employment, Ability and Motivation (STREAM) who reported no MSP at baseline. Measures included physical, emotional, mental, and psychological job demands, social support and autonomy. Predictors of MSP were studied by logistic regression analyses. Univariate and multivariate analyses with age stratification (45-49, 50-54, 55-59, and 60-64 years) were done to explore differences between age groups. All work characteristics with the exception of autonomy were predictive of the development of MSP, with odds ratios varying from 1.21 (95% CI 1.04-1.40) for mental job demands to 1.63 (95% CI 1.43-1.86) for physical job demands. No clear pattern of age-related differences in the predictors of MSP emerged, with the exception of social support, which was predictive of MSP developing in all age groups except for the age group 60-64 years. Adverse physical and psychosocial work characteristics are associated with MSP. Organisations need to comprehensively assess work environments to ensure that all relevant workplace hazards, physical and psychosocial, are identified and then controlled for across all age groups.

Misclassification due to age grouping in measures of child development.

2015-03-01

Screens for developmental delay generally provide a set of norms for different age groups. Development varies continuously with age, however, and applying a single criterion for an age range will inevitably produce misclassifications. In this report, we estimate the resulting error rate for one example: the cognitive subscale of the Bayley Scales of Infant and Toddler Development (BSID-III). Data come from a general population sample of 594 children (305 male) aged 1 month to 42.5 months who received the BSID-III as part of a validation study. We used regression models to estimate the mean and variance of the cognitive subscale as a function of age. We then used these results to generate a dataset of one million simulated participants and compared their status before and after division into age groups. Finally, we applied broader age bands used in two other instruments and explored likely validity limitations when different instruments are compared. When BSID-III age groups are used, 15% of cases are missed and 15% of apparent cases are false positives. Wider age groups produced error rates from 27% to 46%. Comparison of different age groups suggests that sensitivity in validation studies would be limited, under certain assumptions, to 70% or less. The use of age groups produces a large number of misclassifications. Although affected children will usually be close to the threshold, this may lead to misreferrals. Results may help to explain the poor measured agreement of development screens. Scoring methods that treat child age as continuous would improve instrument accuracy.

In this study, culturally sensitive visual aids designed to help convey drug information to nonliterate female adults who had a prescription for a solid oral dosage form of antibiotic medications were developed and evaluated. The researchers conceptualized the educational messages while a local artist produced the visual aids. Seventy-eight female ambulatory patients were evaluated for comprehension and compliance with antibiotic prescription instructions. The study was conducted in three health centers in Cameroon, West Africa and followed a pre-test, post-test, and follow-up format for three groups: two experimental, and one control. All participants were randomly assigned to either experimental or control groups, 26 patients to each group. Subjects in the experimental groups received visual aids alone or visual aids plus an Advanced Organizer. A comparison of the three groups showed that subjects in the experimental groups scored significantly higher than the control group in both the comprehension and compliance measures.

Cognitive behavioral group therapy for anxiety: recent developments.

Anxiety disorders occur frequently, and can have a negative impact on the quality of people's lives. They often begin at an early age and can have some serious consequences. This article is an overview of the recent studies concerning group cognitive-behavioral interventions for anxiety disorders. In the last few years, anxiety disorder prevention for children and adolescents has become an important focus of research work. Group prevention programs are based on standard cognitive behavioral therapy (CBT) strategies and are aimed at preventing anxiety disorders as early as possible. Numerous cognitive behavioral group therapies for children as well as adults have been well studied. There are many CBT protocols that have been developed for treating specific anxiety disorders. Now, specialized CBT programs are available for individuals who suffer from different anxiety disorders, enabling them to be treated together in groups.

The study reported here was part of a larger study, which evaluated a national clinical leadership development programme with reference to resources, participant experiences, participant outcomes and service impact. The aim of the present study was to evaluate the programme's service impact. Clinical leadership development develops competencies that are expressed in context. The outcomes of clinical leadership development occur at individual, departmental and organisational levels. The methods used to evaluate the service impact were focus groups, group interviews and individual interviews. Seventy participants provided data in 18 separate qualitative data collection events. The data contained numerous accounts of service development activities, initiated by programme participants, which improved service and/or improved the culture of the work setting. Clinical leadership development programmes that incorporate a deliberate service impact element can result in identifiable positive service outcomes. The nuanced relationship between leader development and service development warrants further investigation. This study demonstrates that clinical leadership development can impact on service in distinct and identifiable ways. Clinical leadership development programmes should focus on the setting in which the leadership competencies will be demonstrated. © 2013 John Wiley & Sons Ltd.

This study aimed to elucidate groups at high risk of developing cancer among patients with serologically identified Helicobacter pylori infection and nonatrophic stomach. Annual endoscopy was performed for a mean of 5.4 years in 496 asymptomatic middle-aged men who were H. pylori antibody-positive and pepsinogen (PG) test-negative. Subjects were stratified according to the activity of H. pylori-associated gastritis measured by serum levels of PG and H. pylori antibody, and/or by endoscopic findings of rugal hyperplastic gastritis (RHG), and cancer development was investigated. During the study period, seven cases of cancer developed in the cohort (incidence rate, 261/100,000 person-years), with 85.7% developing in the group showing a PGI/II ratio ≤ 3.0, reflecting active inflammation-based high PGII levels. Cancer incidence was significantly higher in this group (750/100,000 person-years) than in groups with less active gastritis. Furthermore, cancer incidence for this group was significantly higher in the subgroup with high H. pylori antibody titers than in the low-titer subgroup. Meanwhile, endoscopic findings revealed that 11.7% of subjects showed RHG reflecting localized highly active inflammation, and cancer risk was significantly higher in patients with RHG than in patients without. Combining the two serum tests and endoscopic examination for RHG allowed identification of subjects with more active gastritis and higher cancer risk. No cancer development was observed in these high-risk subjects after H. pylori eradication. Subjects with highly active gastritis identified by the two serological tests and endoscopic RHG constitute a group at high risk of cancer development with H. pylori-infected nonatrophic stomach.

Thyroid hormones are crucial for a proper development of the central nervous system (CNS), skeleton and tooth buds. They are important from the early stages of fetal development. The aim of the study was to evaluate the mental development of children with congenital hypothyroidism detected in screening and to determine the effect of TSH, level of thyroid hormones during observation, perinatal factors as well as parental and environmental factors on the children's IQ. 44 children (28 girls and 16 boys) aged 3.5-18 years (mean age 7.3+/- 3.5) were enrolled in the study. The subjects' mental development was analyzed. General intelligence quotient was measured on verbal and non-verbal scale and chosen parameters of mental development were measured. The evaluation of mental development was performed in two age groups: group A - 20 patients in the age range 3.5-5.9 years (mean age 5.3+/-0.8) tested using the Columbus method, and group B - 24 patients in the age range 6-18 years (mean age 10.3+/-2.2) tested on the Wechsler Scale. The intelligence quotient (IQ) in both groups was within the average IQ range on Wechsler scale. Mean IQ values on verbal and non-verbal scale were comparable and within the average IQ range on Wechsler scale. The level of intelligence in group A correlated, on the brink of statistical significance (IS), with the education level of the parents (r=0.32; p=0.0934), while in the group B - IS correlated with birth weight (r=0.62; p=0.00247), it correlated on the brink of statistical significance with the education level of parents (r=0.4; p=0.0532) and mother's age (r=0.41; p=0.0514). The level of intelligence on verbal scale in group B, statistically significant, positively correlated with the body mass at birth (r=0.62; p=0.00147) and negatively with the mean value of TSH in 2-year follow-up period (r=-0.47; p=0.0381). The level of general intelligence and on verbal and non-verbal scale did not correlate with the time of commencement of therapy with LT4, place of residence or TSH value in the screening test. 1. Mental development of the studied children with CH was within normal range. 2. Out of all measured parameters determining mental development, tasks in mathematics, analysis and synthesis, visual concentration and concentration on the hearing level had worst results. 3. The level of TSH in the screening test had no effect on the mental development of children with CH. 4. Out of all environmental factors, parental education influenced the mental development of the studied children.

Social networking sites (SNSs) such as Facebook have the potential to enhance online public health interventions, in part, as they provide social exposure and reinforcement. The objective of the study was to evaluate whether social exposure provided by SNSs enhances the effects of online public health interventions. As a sample intervention, we developed Food Hero, an online platform for nutritional education in which players feed a virtual character according to their own nutritional needs and complete a set of virtual sport challenges. The platform was developed in 2 versions: a "private version" in which a user can see only his or her own score, and a "social version" in which a user can see other players' scores, including preexisting Facebook friends. We assessed changes in participants' nutritional knowledge using 4 quiz scores and 3 menu-assembly scores. Monitoring feeding and exercising attempts assessed engagement with the platform. The 2 versions of the platform were randomly assigned between a study group (30 members receiving the social version) and a control group (33 members, private version). The study group's performance on the quizzes gradually increased over time, relative to that of the control group, becoming significantly higher by the fourth quiz (P=.02). Furthermore, the study group's menu-assembly scores improved over time compared to the first score, whereas the control group's performance deteriorated. Study group members spent an average of 3:40 minutes assembling each menu compared to 2:50 minutes in the control group, and performed an average of 1.58 daily sport challenges, compared to 1.21 in the control group (P=.03). This work focused on isolating the SNSs' social effects in order to help guide future online interventions. Our results indicate that the social exposure provided by SNSs is associated with increased engagement and learning in an online nutritional educational platform.

OBJECTIVE This study was performed to identify the angiographic features of hemorrhagic-onset moyamoya disease (MMD) in comparison with those of patients with ischemic-onset MMD. METHODS This case-control study compared the data set of the Japan Adult Moyamoya (JAM) Trial with the angiographic data of adult patients with ischemic-onset MMD. The authors analyzed angiograms obtained at onset, classifying the collaterals into 3 subtypes: lenticulostriate anastomosis, thalamic anastomosis, and choroidal anastomosis. They then compared the extent of these collaterals, as indicated by the collateral development grade from 0 to 2 in each subtype, between the JAM Trial group and the ischemic-onset group. They also compared the involvement of the posterior cerebral artery (PCA) and Suzuki's angiographic staging between each group. RESULTS Among 89 ischemic-onset patients, 103 symptomatic hemispheres in 80 patients were analyzed and compared with 75 hemorrhagic hemispheres from the JAM Trial. The hemorrhagic-onset patients showed a significantly higher proportion of thalamic anastomosis (p = 0.043) and choroidal anastomosis (< 0.001), as indicated by grade 2 in each subtype, compared with ischemic-onset patients. Suzuki's angiographic staging was significantly higher in the hemorrhagic group (< 0.038). There was no difference in the extent of lenticulostriate anastomosis and PCA involvement between the groups. CONCLUSIONS In adult MMD, the characteristic pattern of the abnormal vascular networks at the base of the brain is different between each onset type. In light of the more prominent development of thalamic and choroidal anastomosis in the JAM Trial group in the present study, development of these collaterals, especially the choroidal collateral extending beyond the lateral ventricle, may play a critical role in hemorrhagic presentation in MMD.

The main goal in the present study was to compare follicular development and estradiol levels after ovarian stimulation in pituitary suppressed normally ovulating women undergoing IVF, using highly purified urinary follicle stimulating hormone (FSH) (u-FSH-HP) and recombinant FSH (rec-FSH). A secondary variable in our study was embryo implantation potential, which is closely related to appropriate follicular development and oocyte competence. For the main purpose of this study, 30 IVF patients (group 1) were treated during IVF consecutive cycles, using the same stimulation protocol, with u-FSH-HP in the first treatment study cycle and rec-FSH in the second one. As a control group (group 2) for implantation rates obtained in cycles treated with rec-FSH, 30 additional IVF patients were included who underwent a second IVF attempt again with u-FSH-HP. The total dose of FSH used and ovarian response obtained in terms of estradiol plasma levels and the total number of growing follicles on the day of human chronic gonadotropin (HCG) injection were similar in both treatment cycles in group 1 but better follicular dynamics and oocyte maturity were obtained with rec-FSH. The implantation rate was significantly higher in rec-FSH treated cycles in patients in group 1 than in control women (group 2). rec-FSH is more efficacious than u-FSH-HP when used in the same patient in inducing multiple follicular development in down-regulated cycles as indicated by ovarian performance and oocyte maturity. In addition, rec-FSH yields significantly higher implantation rates than u-FSH-HP when used in patients undergoing their second IVF attempt.

The aim of the present study was to assess the findings, reported in earlier studies, that individuals with autism spectrum disorders process visuo-spatial tasks faster than typically developing control persons. The participants in the present study were children and adolescents with Asperger syndrome (AS) or high-functioning autism (HFA) (N = 13), and a matched group of typically developing children and adolescents (N = 13). The results showed that the participants in the clinical group performed marginally less well than those in the control group on both the Block Design Test and the Embedded Figures Test, but the differences were not statistically significant. Thus, earlier findings suggesting that individuals with autism spectrum disorders solve non-social cognitive tasks faster than typically developing control persons were not replicated. The results are discussed with special reference to the hypothesis of weak central coherence.

To reveal the effect of diet, bowel functions and toilet habits on the development of anal fissure. One hundred patients complaining of anal fissure were included to the case group; and one hundred age- and gender-matched patients referred for other reasons except for anorectal complaints were included to the control group. The information was obtained by face to face interviews using questionnaires. Statistically significant differences were found in coffee, fruit, and meat consumption between the groups. The patients suffering from anal fissure avoided paprika consumption. The rate of anal fissure incidence was higher in squat toilet users. This study is the first study which evaluates the risk factors such as paprika consumption and squat toilet usage that are specific to Eastern culture. Further studies including large numbers of population are needed to evaluate different risk factors for anal fissure development (Tab. 2, Ref. 11). Full Text (Free, PDF) www.bmj.sk.

The purpose of this study is to determine the impact of repetitive transcranial stimulation (rTMS) treatment during pregnancy on neurodevelopment of children. Women who were treated with rTMS during pregnancy and delivered liveborn children between 2008 and 2013 were selected. A control group consisted of children whose mothers had a history of untreated depression during their pregnancy (N = 26). Early developmental characteristics of all the children in the study were evaluated, and their developmental levels were determined using the Ankara Developmental Screening Inventory. The mean age of the children in the rTMS treatment group was 32.4 months (range 16-64 months), and that of the untreated group was 29.04 (range 14-63 months). Jaundice (N = 2) and febrile convulsion (N = 1) were the reported medical conditions in the children of the rTMS-treated group; jaundice (N = 3) and low birth weight (N = 1) were reported in the untreated group. In the rTMS group, mothers' perception of delay in language development was observed, but there were not any statistically significant differences in the prevalence rate compared with the untreated group (OR = 0.38; 95% CI 0.0860-1.6580). Our results suggest that rTMS exposure during pregnancy is not associated with poorer cognitive or motor development outcomes in children aged 18-62 months. Although language development as reported by the mothers was found to be poorer than expected in the rTMS-treated group, the delay was found to be similar to the language delay observed in offspring of untreated mothers, as reported in previous studies of prenatal depression treated with selective serotonin reuptake inhibitors. © 2014 International Neuromodulation Society.

In the framework of a CEC-research program in radiation protection, the uptake and subsequent translocation of radionuclides in potato plants is studied. Results from these studies will be used to further refine computational models applied in calculating doses and in decision making after a potential nuclear fallout. Potatoes are an important staple food crop in western European countries. Foliar absorption of radionuclides plays a major role for the contamination of agricultural products during the first vegetation period after a nuclear fallout. This study aims at investigating the influence of the time-point of contamination on crop radionuclide content. Three groups ofmore » potato plants were of contaminated with an aqueous solution {sup 134}CsCl at three different time-points: Group A: First leaves were fully developed. Group B: Immediately before onset of flowering (4 weeks after group A). Group C: Onset of senescence (8 weeks after group A). Plants were harvested 7, 14, 21, and 28 days after each contamination, and after full tuber development. The distribution of {sup 134}Cs within the plants was studied in three compartments: contaminated part, newly grown part, and subterranean part (roots and tubers). A steady translocation of {sup 134}CS from the contaminated parts into the other parts of the plants was observed in all three groups. The highest radionuclide content of the crop was observed in group B, i.e. in fully developed plants: 58 {+-} 3% (n = 4) of the originally applied radioactivity was found in the tubers. This experiment clearly identified the beginning of tuber formation to be the most critical time for a foliar contamination. These results serve as an important experimental verification of parameters used in computational radioecological models of radionuclide transport through the biosphere.« less

Scar retraction due to exposed bone in palatoplasty is the leading cause of constricted maxilla. Modern techniques have focused on minimizing the effects of scarring by reducing the exposure of the bone area. The objective of the study was to compare the palatal mucoperiosteal detachment with minimal lateral incision, followed by their synthesis, with the maintenance of lateral areas for relaxation (similar to the von Langenbeck technique) and evaluate the transversal development of the maxilla. A prospective, randomized study was conducted, in which the molding of the dental arch of 14 pigs in 2 stages (at 1 month and 5 months) was performed. The pigs were divided into 3 groups: group 1 underwent lateral incision of the palate for mucoperiosteal detachment and maintenance of bone exposure; group 2 underwent mucoperiosteal palatal detachment with lateral access and no bone exposure; and group 3, the control animals, did not undergo any surgical procedures. Measurements of the dental arches were compared between the groups to assess differences in the development of the maxillary transverse diameter. There were no animals lost during the study. Group 1 showed greater growth restriction of the transverse diameter of the maxilla (36%) when compared with groups 2 (56%) and 3 (59%). Groups 2 and 3 showed similar transverse maxillary development, with no statistical difference. The technique of mucoperiosteal detachment without lateral relief incision has the advantage of reducing future morbidity of a constricted maxilla. This study demonstrated that the technique described can reduce rates of maxillary underdevelopment, a significant complication inherent in the procedure for palatoplasty. The lateral incisions reduce maxillary growth by approximately 20% as compared with this technique. Level II of evidence.

Systematic ethics support in community health services in Norway is in the initial phase. There are few evaluation studies about the significance of ethics reflection on care. The aim of this study was to evaluate systematic ethics reflection in groups in community health (including nursing homes and residency), - from the perspectives of employees participating in the groups, the group facilitators and the service managers. The reflection groups were implemented as part of a research and development project. A mixed-methods design with qualitative focus group interviews, observations and written reports were used to evaluate. The study was conducted at two nursing homes, two home care districts and a residence for people with learning disabilities. Participants were employees, facilitators and service managers. The study was guided by ethical standard principles and was approved by the Norwegian Social Science Data Services. We found support for ethics reflection as a valuable measure to strengthen clinical practice. New and improved solutions, more cooperation between employees, and improved collaboration with patients and their families are some of the results. No negative experiences were found. Instead, the ethics reflection based on experiences and challenges in the workplace, was described as a win-win situation. The evaluation also revealed what is needed to succeed and useful tips for further development of ethics support in community health services. Ethics reflection groups focusing on ethical challenges from the participants' daily work were found to be significant for improved practice, collegial support and cooperation, personal and professional development among staff, facilitators and managers. Resources needed to succeed were managerial support, and anchoring ethics sessions in the routine of daily work.

Grouping structures arise naturally in many statistical modeling problems. Several methods have been proposed for variable selection that respect grouping structure in variables. Examples include the group LASSO and several concave group selection methods. In this article, we give a selective review of group selection concerning methodological developments, theoretical properties and computational algorithms. We pay particular attention to group selection methods involving concave penalties. We address both group selection and bi-level selection methods. We describe several applications of these methods in nonparametric additive models, semiparametric regression, seemingly unrelated regressions, genomic data analysis and genome wide association studies. We also highlight some issues that require further study. PMID:24174707

Strategies for Improving Power in School-Randomized Studies of Professional Development.

Kelcey, Ben; Phelps, Geoffrey

2013-12-01

Group-randomized designs are well suited for studies of professional development because they can accommodate programs that are delivered to intact groups (e.g., schools), the collaborative nature of professional development, and extant teacher/school assignments. Though group designs may be theoretically favorable, prior evidence has suggested that they may be challenging to conduct in professional development studies because well-powered designs will typically require large sample sizes or expect large effect sizes. Using teacher knowledge outcomes in mathematics, we investigated when and the extent to which there is evidence that covariance adjustment on a pretest, teacher certification, or demographic covariates can reduce the sample size necessary to achieve reasonable power. Our analyses drew on multilevel models and outcomes in five different content areas for over 4,000 teachers and 2,000 schools. Using these estimates, we assessed the minimum detectable effect sizes for several school-randomized designs with and without covariance adjustment. The analyses suggested that teachers' knowledge is substantially clustered within schools in each of the five content areas and that covariance adjustment for a pretest or, to a lesser extent, teacher certification, has the potential to transform designs that are unreasonably large for professional development studies into viable studies. © The Author(s) 2014.

Few studies have evaluated the association between incident chronic kidney disease (CKD) and related complications, especially in elderly population. We attempted to verify the association between GFR and concurrent CKD complications and elucidate the temporal relationship between incident CKD and new CKD complications in a community-based prospective elderly cohort. We analyzed the available data from 984 participants in the Korean Longitudinal Study on Health and Aging. Participants were categorized into 6 groups according to eGFR at baseline examination (≥90, 75-89, 60-74, 45-59, 30-44, and <30 ml/min/1.73 m(2)). The mean age of study population was 76 ± 9.1 years and mean eGFR was 72.3 ± 17.0 ml/min/1.73 m(2). Compared to eGFR group 1, the odds ratio (OR) for hypertension was 2.363 (95% CI, 1.299-4.298) in group 4, 5.191 (2.074-12.995) in group 5, and 13.675 (1.611-115.806) in group 6; for anemia, 7.842 (2.265-27.153) in group 5 and 13.019 (2.920-58.047) in group 6; for acidosis, 69.580 (6.770-715.147) in group 6; and for hyperkalemia, 19.177 (1.798-204.474) in group 6. Over a 5-year observational period, CKD developed in 34 (9.6%) among 354 participants with GFR ≥ 60 ml/min/1.73 m(2) at basal examination. The estimated mean number of new complications according to analysis of co-variance was 0.52 (95% CI, 0.35-0.68) in subjects with incident CKD and 0.24 (0.19-0.29) in subjects without CKD (p = 0.002). Subjects with incident CKD had a 2.792-fold higher risk of developing new CKD complications. A GFR level of 52.4 ml/min/1.73 m(2) (p = 0.032) predicted the development of a new CKD complication with a 90% sensitivity. In an elderly prospective cohort, CKD diagnosed by current criteria is related to an increase in the number of concurrent CKD complications and the development of new CKD complications.

Psychological collectivism: a measurement validation and linkage to group member performance.

The 3 studies presented here introduce a new measure of the individual-difference form of collectivism. Psychological collectivism is conceptualized as a multidimensional construct with the following 5 facets: preference for in-groups, reliance on in-groups, concern for in-groups, acceptance of in-group norms, and prioritization of in-group goals. Study 1 developed and tested the new measure in a sample of consultants. Study 2 cross-validated the measure using an alumni sample of a Southeastern university, assessing its convergent validity with other collectivism measures. Study 3 linked scores on the measure to 4 dimensions of group member performance (task performance, citizenship behavior, counterproductive behavior, and withdrawal behavior) in a computer software firm and assessed discriminant validity using the Big Five. The results of the studies support the construct validity of the measure and illustrate the potential value of collectivism as a predictor of group member performance.

To assess the effect of metformin in controlling Gestational Diabetes Mellitus (GDM) in women with Polycystic Ovarian Syndrome (PCOS). Comparative cohort study. Gynecology Clinics of Mamji Hospital, Karachi, from 2008 to 2010. Patients who had been diagnosed Polycystic Ovarian Syndrome (PCOS) with hyperinsulinemia and conceived and continued pregnancy, were divided in two groups; 50 patients received metformin throughout pregnancy and 32 did not. Development of GDM was ascertained in both groups. The patients were followed throughout pregnancy and in puerperium with OGTT as per WHO criteria. Primary outcome measure was development of gestational diabetes mellitus. Comparison of continuous variables was done using student 't' test. For categorical variables, frequency and percentages are reported while, odds ratio is also estimated for GDM during pregnancy. A total of 82 women with PCOS were included in this study, out of whom, 50 patients received metformin treatment while 32 patients did not. Pregnant women with PCOS in both groups were comparable in age, weight, parity and BMI. Mean fasting insulin levels at beginning of study entry were 17.22 ± 2.3 mIU/L and 16.93 ± 2.28 mIU/L in metformin and no metformin group respectively (p=0.589). Mean fasting blood sugar levels were 94.54 mg/dl in metformin and 99.59 mg/dl in no metformin group p < 0.001. A total of 5 (10%) patients in metformin group developed GDM while 11 (34.37% OR 4.71, p = 0.01) developed GDM in no metformin group. Patients not receiving metformin were 4.7 times likely to have GDM (OR: 4.71) compared to those who received it. The frequency of gestational diabetes, was significantly higher in patients with PCOS who had not received metformin compared to those who did.

Objective Patient-centered clinical trial design and execution is becoming increasingly important. No best practice guidelines exist despite a key stakeholder declaration to create more effective engagement models. This study aims to gain a better understanding of attitudes and practices for engaging patient groups so that actionable recommendations may be developed. Methods Individuals from industry, academic institutions, and patient groups were identified through Clinical Trials Transformation Initiative and Drug Information Association rosters and mailing lists. Objectives, practices, and perceived barriers related to engaging patient groups in the planning, conduct, and interpretation of clinical trials were reported in an online survey. Descriptive and inferential statistical analysis of survey data followed a literature review to inform survey questions. Results Survey respondents (n = 179) valued the importance of involving patient groups in research; however, patient group respondents valued their contributions to research protocol development, funding acquisition, and interpretation of study results more highly than those contributions were valued by industry and academic respondents (all p < .001). Patient group respondents placed higher value in open communications, clear expectations, and detailed contract execution than did non–patient group respondents (all p < .05). Industry and academic respondents more often cited internal bureaucratic processes and reluctance to share information as engagement barriers than did patient group respondents (all p < .01). Patient groups reported that a lack of transparency and understanding of the benefits of collaboration on the part of industry and academia were greater barriers than did non–patient group respondents (all p< .01). Conclusions Despite reported similarities among approaches to engagement by the three stakeholder groups, key differences exist in perceived barriers and benefits to partnering with patient groups among the sectors studied. This recognition could inform the development of best practices for patient-centered clinical trial design and execution. Additional research is needed to define and optimize key success factors.

Despite reported similarities among approaches to engagement by the three stakeholder groups, key differences exist in perceived barriers and benefits to partnering with patient groups among the sectors studied. This recognition could inform the development of best practices for patient-centered clinical trial design and execution. Additional research is needed to define and optimize key success factors.

Group housing is considered to be important for rats, which are highly sociable animals. Single housing may impact behaviour and levels of circulating stress hormones. Rats are typically used in the toxicological evaluation of insulin analogues. Human insulin (HI) is frequently used as a reference compound in these studies, and a comparator model of persistent exposure by HI infusion from external pumps has recently been developed to support toxicological evaluation of long-acting insulin analogues. However, this model requires single housing of the animals. Developing an insulin-infusion model which allows group housing would therefore greatly improve animal welfare. The aim of the present study was to investigate the suitability of implantable infusion pumps for HI infusion in group-housed rats. Group housing of rats implanted with a battery-driven pump proved to be possible. Intravenous infusion of HI lowered blood glucose levels persistently for two weeks, providing a comparator model for use in two-week repeated-dose toxicity studies with new long-acting insulin analogues, which allows group housing, and thereby increasing animal welfare compared with an external infusion model.

Influence of culture and language sensitive physics on science attitude enhancement

NASA Astrophysics Data System (ADS)

Morales, Marie Paz E.

2015-12-01

The study critically explored how culture and language sensitive curriculum materials in physics improve Pangasinan learners' attitude towards science. Their cultural dimensions, epistemological beliefs, and views on integration of culture and language in the teaching and learning process determined their cultural preference or profile. Design and development of culture and language sensitive curriculum materials in physics were heavily influenced by these learners' cultural preference or profile. Pilot-study using interviews and focus group discussions with natives of Pangasinan and document analysis were conducted to identify the culture, practices, and traditions integrated in the lesson development. Comparison of experimental participants' pretest and posttest results on science attitude measure showed significant statistical difference. Appraisal of science attitude enhancement favored the experimental group over the control group. Qualitative data deduced from post implementation interviews, focus group discussions, and journal log entries showed the same trend in favor of the experimental participants. The study revealed that culture and language integration in the teaching and learning process of physics concepts enabled students to develop positive attitude to science, their culture, and native language.

Group Sequential Testing of the Predictive Accuracy of a Continuous Biomarker with Unknown Prevalence

PubMed Central

Koopmeiners, Joseph S.; Feng, Ziding

2015-01-01

Group sequential testing procedures have been proposed as an approach to conserving resources in biomarker validation studies. Previously, Koopmeiners and Feng (2011) derived the asymptotic properties of the sequential empirical positive predictive value (PPV) and negative predictive value curves, which summarize the predictive accuracy of a continuous marker, under case-control sampling. A limitation of their approach is that the prevalence can not be estimated from a case-control study and must be assumed known. In this manuscript, we consider group sequential testing of the predictive accuracy of a continuous biomarker with unknown prevalence. First, we develop asymptotic theory for the sequential empirical PPV and NPV curves when the prevalence must be estimated, rather than assumed known in a case-control study. We then discuss how our results can be combined with standard group sequential methods to develop group sequential testing procedures and bias-adjusted estimators for the PPV and NPV curve. The small sample properties of the proposed group sequential testing procedures and estimators are evaluated by simulation and we illustrate our approach in the context of a study to validate a novel biomarker for prostate cancer.

The purpose of this study was to determine whether α-lipoic acid and fisetin have protective effects against cataract in a streptozotocin-induced experimental cataract model. Twenty-eight male BALB/C mice were made diabetic by the intraperitoneal administration of streptozotocin (200 mg/kg). Three weeks after induction of diabetes, mice were divided randomly into 4 groups in which each group contained 7 mice; fisetin-treated group (group 1), α-lipoic acid-treated group (group 2), fisetin placebo group (group 3), α-lipoic acid placebo group (group 4). Fisetin and α-lipoic acid were administered intraperitoneally weekly for 5 weeks. Cataract development was assessed at the end of 8 weeks by slit lamp examination, and cataract formation was graded using a scale. All groups developed at least grade 1 cataract formation. In the fisetin-treated group, the cataract stages were significantly lower than in the placebo group (p = 0.02). In the α-lipoic acid-treated group, the cataract stages were lower than in the placebo group but it did not reach to a significant value. Both fisetin and α-lipoic acid had a protective effect on cataract development in a streptozotocin-induced experimental cataract model. The protective effect of fisetin appears as though more effective than α-lipoic acid.

Ethical competence, which is reflected in the ability to detect ethical challenges in clinical situations and engage in deliberate thinking on ethical actions, is one of the core competencies of nursing practice. The purpose of this study was to develop and implement an interactive situational e-learning system, integrating nursing ethical decisions into a nursing ethics course, and to evaluate the effects of this course on student nurses' ethical decision-making competence. The project was designed to be carried out in two phases. In the first phase, an interactive situated e-learning system was developed and integrated into the nursing ethics course. The second phase involved implementing the course and evaluating its effects in a quasi-experimental study. The course intervention was designed for 2h per week over one semester (18weeks). A total of 100 two-year technical college nursing students in their second year of the program participated in the study, with 51 in the experimental group and 49 in the control group. After completing the course, the students in the experimental group showed significant improvement in nursing ethical decision-making competence, including skills in "raising questions," "recognizing differences," "comparing differences," "self-dialogue," "taking action," and "identifying the implications of decisions made," compared to their performance prior to the class. After controlling for factors influencing learning effects, students in the experimental group showed superiority to those in the control group in the competency of "recognizing differences." The students in the experimental group reported that the course pushed them to search for and collect information needed to resolve the ethical dilemma. The interactive situational e-learning system developed by our project was helpful in developing the students' competence in ethical reasoning. The e-learning system and the situational teaching materials used in this study may be applicable in nursing and related professional ethics courses. Copyright © 2017 Elsevier Ltd.

National facilities study. Volume 5: Space research and development facilities task group

NASA Technical Reports Server (NTRS)

1994-01-01

With the beginnings of the U.S. space program, there was a pressing need to develop facilities that could support the technology research and development, testing, and operations of evolving space systems. Redundancy in facilities that was once and advantage in providing flexibility and schedule accommodation is instead fast becoming a burden on scarce resources. As a result, there is a clear perception in many sectors that the U.S. has many space R&D facilities that are under-utilized and which are no longer cost-effective to maintain. At the same time, it is clear that the U.S. continues to possess many space R&D facilities which are the best -- or among the best -- in the world. In order to remain world class in key areas, careful assessment of current capabilities and planning for new facilities is needed. The National Facility Study (NFS) was initiated in 1992 to develop a comprehensive and integrated long-term plan for future aerospace facilities that meets current and projected government and commercial needs. In order to assess the nation's capability to support space research and development (R&D), a Space R&D Task Group was formed. The Task Group was co-chaired by NASA and DOD. The Task Group formed four major, technologically- and functionally- oriented working groups: Human and Machine Operations; Information and Communications; Propulsion and Power; and Materials, Structures, and Flight Dynamics. In addition to these groups, three supporting working groups were formed: Systems Engineering and Requirements; Strategy and Policy; and Costing Analysis. The Space R&D Task Group examined several hundred facilities against the template of a baseline mission and requirements model (developed in common with the Space Operations Task Group) and a set of excursions from the baseline. The model and excursions are described in Volume 3 of the NFS final report. In addition, as a part of the effort, the group examined key strategic issues associated with space R&D facilities planning for the U.S., and these are discussed in Section 4 of this volume.

Reporting standards for research in psychology: why do we need them? What might they be?

PubMed

2008-12-01

In anticipation of the impending revision of the Publication Manual of the American Psychological Association, APA's Publications and Communications Board formed the Working Group on Journal Article Reporting Standards (JARS) and charged it to provide the board with background and recommendations on information that should be included in manuscripts submitted to APA journals that report (a) new data collections and (b) meta-analyses. The JARS Group reviewed efforts in related fields to develop standards and sought input from other knowledgeable groups. The resulting recommendations contain (a) standards for all journal articles, (b) more specific standards for reports of studies with experimental manipulations or evaluations of interventions using research designs involving random or nonrandom assignment, and (c) standards for articles reporting meta-analyses. The JARS Group anticipated that standards for reporting other research designs (e.g., observational studies, longitudinal studies) would emerge over time. This report also (a) examines societal developments that have encouraged researchers to provide more details when reporting their studies, (b) notes important differences between requirements, standards, and recommendations for reporting, and (c) examines benefits and obstacles to the development and implementation of reporting standards.

Recent study from our laboratory showed that patients with diabetes are at a higher risk of developing kidney cancer. In the current study, we have screened whole human DNA genome from healthy control, patients with diabetes or renal cell carcinoma (RCC) or RCC+diabetes. We found that 883 genes gain/163 genes loss of copy number in RCC+diabetes group, 669 genes gain/307 genes loss in RCC group and 458 genes gain/38 genes loss of copy number in diabetes group, after removing gain/loss genes obtained from healthy control group. Data analyzed for functional annotation enrichment pathways showed that control group had the highest number (280) of enriched pathways, 191 in diabetes+RCC group, 148 in RCC group, and 81 in diabetes group. The overlap GO pathways between RCC+diabetes and RCC groups showed that nine were enriched, between RCC+diabetes and diabetes groups was four and between diabetes and RCC groups was eight GO pathways. Overall, we observed majority of DNA alterations in patients from RCC+diabetes group. Interestingly, insulin receptor (INSR) is highly expressed and had gains in copy number in RCC+diabetes and diabetes groups. The changes in INSR copy number may use as a biomarker for predicting RCC development in diabetic patients. PMID:25821562

To investigate the status of pubertal development in children born with assisted reproductive technology (ART). A retrospective analysis was performed on the pubertal development data of children born with ART in Peking University Third Hospital from 1994 to 2003 (ART group). The data in the cross-sectional study "Reports on the Physical Fitness and Health Research of Chinese School Students in 2010" were used as a control. The age at menarche and the age at spermarche were compared between the two groups. The status of pubertal development in the overweight and obese children in the ART group was evaluated to investigate the correlation between pubertal development and body mass index (BMI). A total of 200 children born with ART were enrolled in this study, and 72 of them (41 males and 31 females) completed the survey (response rate=36.0%). In the ART group, the mean age at spermarche and the mean age at menarche were 13.9 years (95%CI: 13.7-14.3 years) and 12.2 years (95%CI: 11.8-12.6 years), respectively. There were no significant differences in the age at spermarche and the age at menarche between the ART and control groups (P>0.05). In the ART group, there were no significant differences in the age at spermarche and the age at menarche between the overweight and obese children and the normal weight children (P>0.05). There were also no significant differences in overweight rate and obesity rate between the children in the ART group and the adolescents in Beijing (P>0.05). In the ART group, there was no significant correlation between the age at spermarche or menarche and BMI (P>0.05). No delayed or precocious puberty is observed in children born with ART. This is consistent with the normal control data. And there is no significant correlation between pubertal development and BMI in children born with ART.

This nationwide population-based retrospective cohort study evaluated the risk of developing prostate cancer among patients with gonorrhea. We identified cases of newly diagnosed gonorrhea in men between 2000 and 2010 from the Taiwan National Health Insurance Research Database. Each patient with gonorrhea was matched to four controls, based on age and index year. All subjects were followed up from the index date to December 31, 2010. The Cox proportional hazards regression model was used to assess the risk of prostate cancer. A total of 355 men were included in the study group, and 1,420 age-matched subjects without gonorrhea were included in the control group. After adjusting for age, comorbidities, urbanization level, hospital level, and monthly income, gonorrhea was significantly associated with an increased risk of prostate cancer (adjusted hazard ratio = 5.66, 95% confidence interval = 1.36-23.52). Men aged 45-70 years and those with lower monthly income were more strongly associated with prostate cancer in the study group than the control group. The higher risk for developing prostate cancer were also found in those without syphilis, without genital warts, without diabetes mellitus, without chronic obstructive pulmonary disease, without benign prostatic hypertrophy, without chronic prostatitis, and without alcoholism. The Kaplan-Meier analysis showed the risk of prostate cancer was significantly higher in the study group than in the control group. Gonorrhea may be involved in the development of prostate cancer. More intensive screening and prevention interventions for prostate cancer should be recommended in men with gonorrhea.

Maternal folic acid supplementation has been recommended prior to and during the first trimester of pregnancy to reduce the risk of infant neural tube defects. However, an uncertain relationship between folic acid supplementation during pregnancy and development of childhood asthma exists. Recent data show a methyl donor-rich diet could increase the risk of developing allergic airway disease through DNA methylation and aberrant gene transcription. This study evaluated the effect of folic acid supplementation during pregnancy on airway remodeling and allergic airway disease vulnerability in a mouse asthma model. BALB/c mice were divided into four groups according to gestational folic acid supplementation and postnatal ovalbumin (OVA) exposure: Group 1 (whole pregnancy folic acid supplementation + OVA-exposed group), Group 2 (first gestational week folic acid supplementation + OVA-exposed group), Group 3 (no folic acid supplementation + OVA-exposed group), and Group 4 (control group). Offspring were sacrificed on day 45 for immunohistological and ultrastructural tests. In OVA challenged groups, folic acid supplementation led to a thicker epithelial and subepithelial smooth muscle layer than in the unsupplemented group. Moreover, folic acid supplementation during whole pregnancy (Group 1) was associated with a thicker epithelial and subepithelial smooth muscle layer than folic acid supplementation during the first week of pregnancy (Group 2), suggesting a duration-response relationship. Electron microscopic imaging revealed that structural changes including the loss of epithelial integrity, thickening of basement membrane, and subepithelial fibrosis were more prominent in the folic acid supplementation groups. This study suggested that maternal folic acid supplementation during pregnancy affects airway remodeling and increases the allergic responses induced by ovalbumin challenge in offspring. In addition, the effect size increased as the duration and cumulative dose increased.

The purpose of this study was to develop a multimedia learning program for patients with diabetes mellitus (DM) diet education using standardized patients and to examine the effects of the program on educational skills, communication skills, DM diet knowledge and learning satisfaction. The study employed a randomized control posttest non-synchronized design. The participants were 108 third year nursing students (52 experimental group, 56 control group) at K university in Seoul, Korea. The experimental group had regular lectures and the multimedia learning program for DM diet education using standardized patients while the control group had regular lectures only. The DM educational skills were measured by trained research assistants. The students who received the multimedia learning program scored higher for DM diet educational skills, communication skills and DM diet knowledge compared to the control group. Learning satisfaction of the experimental group was higher than the control group, but statistically insignificant. Clinical competency was improved for students receiving the multimedia learning program for DM diet education using standardized patients, but there was no statistically significant effect on learning satisfaction. In the nursing education system there is a need to develop and apply more multimedia materials for education and to use standardized patients effectively.

Clinical reasoning is the most important competente in the training process of a physician. To develop a method for teaching clinical reasoning based on prototypes of clinical cases. The study was conducted on sixty-four third year medical students. The study and control groups attended lectures and tutorial sessions with patients. The study group attended additionally discussion seminars of prototypical clinical cases. A clinical reasoning test was applied at the start and end of the learning period to both groups. At the end of the study, the opinions of students of the study group were collected in a focus group. After the learning period, both groups significantly increased their clinical reasoning skills. However, the improvement in the study group was more than double than that of the control group. The absolute improvement in the study group was 30.9%. Students interviewed in the focus group were unanimous in expressing their satisfaction in each and every aspect discussed. The teaching of clinical reasoning to third year medical students by means of pattern recognition in seminars with clinical cases improved significantly their skills.

The aim of this study was to develop summary metrics and assess the construct validity for a virtual reality laparoscopic simulator (LapSim) by comparing the learning curves of three groups with different levels of laparoscopic expertise. Three groups of subjects ('expert', 'junior', and 'naïve') underwent repeated trials on three LapSim tasks. Formulas were developed to calculate scores for efficiency ('time-error') and economy of 'motion' ('motion') using metrics generated by the software after each drill. Data (mean +/- SD) were evaluated by analysis of variance (ANOVA). Significance was set at p < 0.05. All three groups improved significantly from baseline to final for both 'time-error' and 'motion' scores. There were significant differences between groups in time error performances at baseline and final, due to higher scores in the 'expert' group. A significant difference in 'motion' scores was seen only at baseline. We have developed summary metrics for the LapSim that differentiate among levels of laparoscopic experience. This study also provides evidence of construct validity for the LapSim.

The objective of this study was to examine the impact of low birth weight and preterm birth on a toddler's inattention and development, including cognitive, language, motor, social-emotional and adaptive behaviors. A total of 105 toddlers enrolled for the study; they were divided into four groups: 40 full-term and normal birth weight (NBW, birth weight greater than 2500 g) toddlers, 24 moderate birth weight (MLBW, birth weight between 2499 and 1500 g) toddlers, 20 very to extremely low birth weight (V-ELBW, 12 between 1000 and 1499 g and 8 lower than 1000 g) toddlers, and 21 term toddlers who were recruited from a clinic of developmental delay as the developmental delay at risk (DDR) group. The Bayley Scales of Infant and Toddler Development-Third Edition (BSID-III) and Disruptive Behavior Rating Scale-Toddler were used. The findings were as follows: (1) DDR group performed worst in BSID-III; (2) although there were no statistical differences among the NBW, MLBW, and V-ELBW groups in BSID-III, the lower the birth weight, the lower the average performance, especially in language, adaptive social behavior, and adaptive practical behavior; and (3) comparing the inattention score, the DDR group was the poorest, normal and V-ELBW groups were the best, and MLBW group was in the middle. In conclusion, low birth weight and preterm delivery affected children's inattention and development of language, adaptive social behavior, and adaptive practical behavior. Copyright © 2012.

To compare macular hole (MH) closure and visual acuity improvement after vitrectomy using SF6 versus C3F8 gas tamponade. The secondary purposes were to report the cumulative incidence of cataract development at 1 year after MH surgery and the proportion of complications. Prospective, randomized study. Thirty-one patients were prospectively randomized to the SF6 group and 28 patients to the C3F8 group. Preoperative data included MH minimum diameter, Early Treatment Diabetic Retinopathy Study (ETDRS) best corrected visual acuity (BCVA), cataract staging, and intraocular pressure (IOP) measurement. Postoperative data included optical coherence tomography confirmation of the closure at 6 weeks and 1 year, and ETDRS BCVA and cataract development/extraction, both 1 year after the MH surgery. Primary MH closure was achieved in 93.3% in the SF6 group and 92.9% in the C3F8 group. Mean ETDRS BCVA improved by 17.7 letters in the SF6 and 16.9 letters in the C3F8 group. The difference in cumulative incidence of cataract development and extraction between both groups was not statistically significant. Regardless of the dye used, similar results were achieved. Finally, the proportion of adverse events was similar in both groups. MH surgery with SF6 gas achieves results similar to C3F8 in terms of visual acuity improvement, MH closure, cataract development/extraction, and adverse events.

Grouped survival data arise often in studies where the disease status is assessed at regular visits to clinic. The time to the event of interest can only be determined to be between two adjacent visits or is right censored at one visit. In data analysis, replacing the survival time with the endpoint or midpoint of the grouping interval leads to biased estimators of the effect size in group comparisons. Prentice and Gloeckler developed a maximum likelihood estimator for the proportional hazards model with grouped survival data and the method has been widely applied. Previous work on sample size calculation for designing studies with grouped data is based on either the exponential distribution assumption or the approximation of variance under the alternative with variance under the null. Motivated by studies in HIV trials, cancer trials and in vitro experiments to study drug toxicity, we develop a sample size formula for studies with grouped survival endpoints that use the method of Prentice and Gloeckler for comparing two arms under the proportional hazards assumption. We do not impose any distributional assumptions, nor do we use any approximation of variance of the test statistic. The sample size formula only requires estimates of the hazard ratio and survival probabilities of the event time of interest and the censoring time at the endpoints of the grouping intervals for one of the two arms. The formula is shown to perform well in a simulation study and its application is illustrated in the three motivating examples. Copyright © 2018 John Wiley & Sons, Ltd.

[Prospective study on the impact of infantile cytomegalovirus infection on growth and development of infants].

To understand the situation of postnatal cytomegalovirus (CMV) infection in Beijing and its impact on infant. From November 2004 to March 2008, a multicenter cohort study on maternal, neonatal and infantile CMV infection was carried out in four hospitals in Beijing. Two hundred and ten infants without congenital infections were enrolled into this study. Their serum IgG antibody to CMV was determined at the age of 1 year. According to the results of CMV DNA at 12 weeks of age and the CMV IgG results at 1 year of age, they were divided into three groups, perinatal infection group, postnatal infection group and postnatal non-infection group. The information of their mothers, the data of their growth and development at 1 year of age, development quotient, their eyes and their auditory function were analyzed. The risk factors of the postnatal cytomegalovirus infection were analyzed by multi-factorial logistic regression. Of the 210 infants, 42 had perinatal infection, 98 had postnatal infection and 70 had no infection. The postnatal cytomegalovirus infection rate was 46.40%, taken into account the congenital infection rate and perinatal infection rate, the total cytomegalovirus infection rate was 66.85% at 1 year of age. The clinical manifestation, developmental status and the quotient of development from three groups at birth and at 1 year of age were analyzed. No significant difference was found. In postnatal cytomegalovirus infection group the rates of breast feeding, mixed feeding and formula feeding were 87.76%, 9.18% and 3.06%, respectively; while in no infection group the rates were 61.43%, 21.43% and 17.14%, respectively(chi(2) = 17.040, P < 0.01). CMV infection is present widely in China. Non-breast feeding is an important protective factor. Postnatal cytomegalovirus infection in infants had no significant impact on the health and development of infants.

To investigate the effect of telomere shortening and other predictive factors of non-alcoholic fatty liver disease (NAFLD) in type 2 diabetes mellitus patients in a 6-year prospective cohort study. A total of 70 type 2 diabetes mellitus (mean age 57.8 ± 6.7 years) patients without NAFLD were included in the study, and 64 of them were successfully followed up 6 years later, excluding four cases with significant alcohol consumption. NAFLD was diagnosed by the hepatorenal ratio obtained by a quantitative ultrasound method using NIH image analysis software. The 39 individuals that developed NAFLD were allocated to group A, and the 21 individuals that did not develop NAFLD were allocated to group B. Fluorescent real-time quantitative polymerase chain reaction was used to measure telomere length. There was no significant difference between the two groups in baseline telomere length; however, at the end of the 6th year, telomere length had become shorter in group A compared with group B. There were significant differences between these two groups in baseline body mass index, waistline, systolic blood pressure, glycated hemoglobin and fasting C-peptide level. In addition, the estimated indices of baseline insulin resistance increased in group A. Fasting insulin level, body mass index, systolic blood pressure at baseline and the shortening of telomere length were independent risk factors of NAFLD in type 2 diabetes mellitus patients. Telomere length became shorter in type 2 diabetes mellitus patients who developed NAFLD over the course of 6 years. Type 2 diabetes mellitus patients who developed NAFLD had more serious insulin resistance compared with those who did not develop NAFLD a long time ago. © 2016 The Authors.

The emergence of online group-buying provides a new consumption pattern for consumers in e-commerce era. However, many consumers realize that their own interests sometimes can't be guaranteed in the group-buying market due to the lack of being regulated. This paper aims to develop effective regulation strategies for online group-buying market. To the best of our knowledge, most existing studies assume that three parties in online group-buying market, i.e. the retailer, the group-buying platform and the consumer, are perfectly rational. To better understand the decision process, in this paper, we incorporate the concept of bounded rationality into consideration. Firstly, a three-parties evolutionary game model is established to study each player's game strategy based on bounded rationality. Secondly, the game model is simulated as a whole by adopting system dynamics to analyze its stability. Finally, theoretical analysis and extensive computational experiments are conducted to obtain the managerial insights and regulation strategies for online group-buying market. Our results clearly demonstrate that a suitable bonus-penalty measure can promote the healthy development of online group-buying market.

Strategies influence neural activity for feedback learning across child and adolescent development.

Learning from feedback is an important aspect of executive functioning that shows profound improvements during childhood and adolescence. This is accompanied by neural changes in the feedback-learning network, which includes pre-supplementary motor area (pre- SMA)/anterior cingulate cortex (ACC), dorsolateral prefrontal cortex (DLPFC), superior parietal cortex (SPC), and the basal ganglia. However, there can be considerable differences within age ranges in performance that are ascribed to differences in strategy use. This is problematic for traditional approaches of analyzing developmental data, in which age groups are assumed to be homogenous in strategy use. In this study, we used latent variable models to investigate if underlying strategy groups could be detected for a feedback-learning task and whether there were differences in neural activation patterns between strategies. In a sample of 268 participants between ages 8 to 25 years, we observed four underlying strategy groups, which were cut across age groups and varied in the optimality of executive functioning. These strategy groups also differed in neural activity during learning; especially the most optimal performing group showed more activity in DLPFC, SPC and pre-SMA/ACC compared to the other groups. However, age differences remained an important contributor to neural activation, even when correcting for strategy. These findings contribute to the debate of age versus performance predictors of neural development, and highlight the importance of studying individual differences in strategy use when studying development.

Operative stabilization is frequently used in the clinical treatment of multiple rib fractures (MRF); however, no ideal material exists for use in this fixation. This study investigates a newly developed biodegradable plate system for the stabilization of MRF. Silk fiber-reinforced polycaprolactone (SF/PCL) plates were developed for rib fracture stabilization and studied using a canine flail chest model. Adult mongrel dogs were divided into three groups: one group received the SF/PCL plates, one group received standard clinical steel plates, and the final group did not undergo operative fracture stabilization (n = 6 for each group). Radiographic, mechanical, and histologic examination was performed to evaluate the effectiveness of the biodegradable material for the stabilization of the rib fractures. No nonunion and no infections were found when using SF-PCL plates. The fracture sites collapsed in the untreated control group, leading to obvious chest wall deformity not encountered in the two groups that underwent operative stabilization. Our experimental study shows that the SF/PCL plate has the biocompatibility and mechanical strength suitable for fixation of MRF and is potentially ideal for the treatment of these injuries.

2017-08-01

This study was undertaken to develop and test a mastery learning program of nursing skills for undergraduate nursing students. In this methodological study, first, the preliminary draft of a mastery learning program to provide training for nursing skills was developed based on Bloom's framework for mastery learning. Second, to test the developed program, a single-blinded, nonequivalent control group nonsynchronized study was conducted on 50 senior nursing students in a University selected by convenient sampling. Thirteen students were assigned to a control group; 13, 12, and 13 of them were assigned to intravenous therapy, transfusion, and patient transfer groups, respectively. The achievement levels and performance scores of the selected nursing skills were measured before and after the completion of the program in all the groups. Lastly, the final program was confirmed based on the results of the program testing. Intravenous therapy, transfusion, and patient transfer were selected as essential nursing skills for the program based on the priorities rated by clinical instructors and staff nurses. The achievement levels of selected nursing skills were determined by Angoff scores. After participating in the program, the proportion of passers and performance scores of the nursing skills in the experimental groups were significantly higher than those in the control group. The final program was confirmed which included a diagnostic test, enrichment activities for the passers and three repetitions of corrective activities and formative assessments for non-passers. The results suggest that a mastery learning program for undergraduate students can lead to better improvement and performance of essential nursing skills. © 2017 Korean Society of Nursing Science

Do drug prices reflect development time and government investment?

Lengthy development times are cited by the pharmaceutical industry as one reason for high drug prices. We compared the prices of different groups of drugs after accounting for development time, government support, market size, and other drug characteristics. We conducted a retrospective study of 180 human therapeutic drugs categorized into 8 drug groups by assembling data on drug development times, government support, drug characteristics, and prices. First, we compared the development time and level of government support across the 8 drug groups. Second, we assessed the independent effect of drug group on median price per day in a multivariable analysis, controlling for development time and all other variables. Thirty percent of antiretroviral drugs had government patents compared with 16% of other infectious disease drugs, 6% of cancer drugs, and less than 6% of any other drug group (P < 0.002). Fifty percent of antiretrovirals had NIH trials listed in the new drug application for approval by the Food and Drug Administration compared with less than 6% of any other drug group (P < 0.001). More antiretroviral and cancer drugs received fast track status and accelerated review during regulatory review by the Food and Drug Administration (P < 0.001). The median price of antiretrovirals was 8 US dollars per day more, cancer drugs 11 US dollars per day more, than the reference group after adjustment for other variables (P < 0.001). Development time was not associated with drug price. Antiretroviral and cancer drugs, even after accounting for development time, are among the most highly priced medications. Notably, drugs with rapid development and more government support did not have lower drug prices.

Organotin compounds, such as tributyltin (TBT) used as an antifouling biocide, can induce masculinization in female mollusks. However, few studies addressing the effect of TBT in fish have been reported. This study was conducted to investigate effects of TBT at environmental levels (1, 10, 100ng/L) on the development of ovary in female cuvier. TBT exposure elevated testosterone levels, increased the ratio of testosterone to 17beta-estradiol and decreased 17beta-estradiol levels in ovaries after 50 days compared to the control. Three stages of follicles (primary growth stage, yolk vesicle stage, vitellogenic stage) were observed in the ovaries of cuvier at the control and 1ng/L TBT group. The ovaries at the 10ng/L TBT group were characterized by the lack of vitellogenic stage follicles and instead had higher proportions of primary growth stage follicles. 100ng/L TBT resulted in follicles that were entirely at the earliest (primary growth stage) stages of development. There was a significant increase in apoptotic ovarian follicular cells judged by TUNEL-positive cell at the 10ng/L TBT group. The TUNEL-positive follicles were observed at the 100ng/L TBT group. The result in the present study showed that TBT at environmentally realistic concentrations can inhibit the ovarian development in fish. Besides the changes of sex hormone induced by TBT, apoptosis appears to be one mechanism affecting ovarian development.

The purposes of this study were to develop a performance assessment instrument for assessing the competence of psychomotor high school students on salt hydrolysis concepts. The design used in this study was the Research & Development which consists of three phases: development, testing and application of instruments. Subjects in this study were high school students in class XI science, which amounts to 93 students. In the development phase, seven validators validated 17 tasks instrument. In the test phase, we divided 19 students into three-part different times to conduct performance test in salt hydrolysis lab work and observed by six raters. The first, the second, and the third groups recpectively consist of five, six, and eight students. In the application phase, two raters observed the performance of 74 students in the salt hydrolysis lab work in several times. The results showed that 16 of 17 tasks of performance assessment instrument developed can be stated to be valid with CVR value of 1,00 and 0,714. While, the rest was not valid with CVR value was 0.429, below the critical value (0.622). In the test phase, reliability value of instrument obtained were 0,951 for the five-student group, 0,806 for the six-student group and 0,743 for the eight-student group. From the interviews, teachers strongly agree with the performance instrument developed. They stated that the instrument was feasible to use for maximum number of students were six in a single observation.

A Randomized Controlled Pilot Intervention Study of a Mindfulness-Based Self-Leadership Training (MBSLT) on Stress and Performance.

PubMed

Sampl, Juliane; Maran, Thomas; Furtner, Marco R

2017-01-01

The present randomized pilot intervention study examines the effects of a mindfulness-based self-leadership training (MBSLT) specifically developed for academic achievement situations. Both mindfulness and self-leadership have a strong self-regulatory focus and are helpful in terms of stress resilience and performance enhancements. Based on several theoretical points of contact and a specific interplay between mindfulness and self-leadership, the authors developed an innovative intervention program that improves mood as well as performance in a real academic setting. The intervention was conducted as a randomized controlled study over 10 weeks. The purpose was to analyze the effects on perceived stress, test anxiety, academic self-efficacy, and the performance of students by comparing an intervention and control group ( n  = 109). Findings demonstrated significant effects on mindfulness, self-leadership, academic self-efficacy, and academic performance improvements in the intervention group. Results showed that the intervention group reached significantly better grade point averages than the control group. Moreover, the MBSLT over time led to a reduction of test anxiety in the intervention group compared to the control group. Furthermore, while participants of the control group showed an increase in stress over time, participants of the intervention group maintained constant stress levels over time. The combination of mindfulness and self-leadership addressed both positive effects on moods and on objective academic performance. The effects demonstrate the great potential of combining mindfulness with self-leadership to develop a healthy self-regulatory way of attaining achievement-related goals and succeeding in high-stress academic environments.

Introduction: Although the survival rate of infants born preterm has increased, the prevalence of developmental problems and motor disorders among this population of infants remains the same. This study investigated the effect of physical activity programs in and out of water on motor performance and neuromuscular development of infants born preterm and had induced immobility by mechanical ventilation. Methods: This study was carried out in Al-Zahra hospital, Tabriz. 76 premature infants were randomly assigned into four groups. One group received daily passive range of motion to all extremities based on the Moyer-Mileur protocol. Hydrotherapy group received exercises for shoulders and pelvic area in water every other day. A combination group received physical activity programs in and out of water on alternating days. Infants in a containment group were held in a fetal position. Duration of study was two weeks ‘from 32 through 33 weeks post menstrual age (PMA). Motor outcomes were measured by the Test of Infant Motor Performance. Neuromuscular developmental was assessed by New Ballard scale and leg recoil and Ankle dorsiflexion items from Dubowitz scale. Data were analyzed using SPSS version 13. Results: TIMP and neuromuscular scores improved in all groups. Motor performance did not differ between groups at 34 weeks PMA. Postural tone of leg recoil was significantly higher in physical activity groups post intervention. Conclusion: Physical activities and containment didn’t have different effects on motor performance in infants born preterm. Leg recoil of neuromuscular development items was affected by physical activity programs. PMID:28299299

The aim of this study was to compare the results of two different modes of using multiple groups (instead of one large group) to identify problems and develop solutions. Many of the complex problems facing organizations today require the use of very large groups or collaborations of groups from multiple organizations. There are many logistical problems associated with the use of such large groups, including the ability to bring everyone together at the same time and location. A field study involved two different organizations and compared productivity and satisfaction of group. The approaches included (a) multiple small groups, each completing the entire process from start to end and combining the results at the end (parallel mode); and (b) multiple subgroups, each building on the work provided by previous subgroups (serial mode). Groups using the serial mode produced more elaborations compared with parallel groups, whereas parallel groups produced more unique ideas compared with serial groups. No significant differences were found related to satisfaction with process and outcomes between the two modes. Preferred mode depends on the type of task facing the group. Parallel groups are more suited for tasks for which a variety of new ideas are needed, whereas serial groups are best suited when elaboration and in-depth thinking on the solution are required. Results of this research can guide the development of facilitated sessions of large groups or "teams of teams."

Developing health services is a key strategy for improving the community health provided by public health nurses. However, an effective educational program for improving their skills in planning such services has not been developed. To describe our program and its evaluation protocol for the education of middle-level public health nurses to improve their skills in developing new health services to fulfil community health needs in Japan. In this randomized control trial, eligible participants in Japan will be randomly allocated to an intervention group and a control wait-list group. We will provide 8 modules of web-based learning for public health nurses from July to October 2018. To ensure fairness of educational opportunity, the wait-list group will participate in the same program as the intervention group after collection of follow-up data of the intervention group. The primary outcomes will be evaluated using the scale of competency measurement of creativity for public health nurses at baseline, immediately after the intervention. Secondary outcomes will be knowledge and performance regarding program development of public health nurses. This study will enable the analysis of the effects of the educational program on public health nurses for improving their competency to develop new health services for fulfilling community health needs and enriching health care systems. We registered our study protocol to the University hospital Medical Information Network- Clinical Trials Registry approved by International Committee of Medical Journal Editors (No. UMIN000032176, April, 2018).

1972-01-01

In a single-blinded study, two groups of 10 healthy subjects were given cephapirin or cephalothin by continuous intravenous infusion for 5 days, 0.5 g every 6 hr for the first day and then 1.0 g every 6 hr for 4 days. Eight of the cephalothin subjects and two of the cephapirin subjects developed phlebitis. Phlebitis was more severe in the cephalothin group and developed more rapidly, necessitating vein changes six times more often than in the cephapirin group. The less irritating properties of cephapirin demonstrated in this study indicate it may be the more useful cephalosporin analogue for intravenous therapy. PMID:4790563

Objective The aim of this study was to provide a systematic safety analysis of gadobutrol after more than 29 million applications in clinical routine. Materials and Methods Forty-two clinical development phase II to IV studies on gadobutrol or comparator and the postmarketing safety surveillance database for gadobutrol (1998–2015) were analyzed. Adverse events (AEs) and drug-related AEs were evaluated in the clinical development database and spontaneous adverse drug reactions (ADRs) in the postmarketing database. Subgroup analyses were run on patients with special medical history and on patients of different age groups. Results In the clinical development studies, 6809 and 2184 patients received gadobutrol or comparators, respectively. The incidence of drug-related AEs was 3.5% for both groups. With the exception of nausea (0.7% related cases in both groups), all other drug-related AEs were 0.3% or less in both groups. Hypersensitivity reactions were sporadic (<0.1%). Patients with history of allergies to contrast agents experienced slightly more drug-related AEs. No differences were seen between age groups. The overall reporting rate of ADRs from postmarketing surveillance was 0.05%. The most frequent ADRs were anaphylactoid/hypersensitivity reactions, nausea, vomiting, and dyspnea. For 3 single-agent reports of nephrogenic systemic fibrosis, using a conservative approach, association with gadobutrol could not be excluded. Conclusions Gadobutrol is well tolerated and has a favorable safety profile for patients of all age groups. PMID:26964075

Chemotherapy: the effect of oral cryotherapy on the development of mucositis.

PubMed

Karagözoğlu, Serife; Filiz Ulusoy, Mehlika

2005-07-01

The aim of this study is to investigate the effect of oral cryotherapy on the development of chemotherapy-induced mucositis in patients administered combined chemotherapy. Mucositis has been of interest to scientists for more than 20 years. Unfortunately, this has not resulted in the development of standard procedures for prevention and management. To cope with this side-effect and to prevent opportunistic infections that may emerge during treatment, attempts are taken to provide preventative and comfort measures. In this context, cryotherapy (oral cooling) has become popular as a cheap and readily applicable method in preventing the developing due the rapid infusion of chemotherapy agents, or decreasing its severity. Study involved 60 patients, 30 of whom were in the study group and 30 in the control group. Ice cubes at a size that can be moved easily in the mouth and whose corners have been smoothed in order that they will not cause irritation in the mouth has been used in oral cryotherapy in the study group. Oral chemotherapy was initiated five minutes before chemotherapy and maintained during venous infusions of etoposide (Vepesid), platinol (Cisplatin), mitomycin (Mitomycin-C) and vinblastin (Velbe) depending on the chemotherapy course. According to Patient-Judged Mucositis Grading, the rate of mucositis is 36.7% in study group and 90.0% in control group, the difference between two groups being statistically significant (P < 0.05). According to Physician-Judged Mucositis Grading, the rate of mucositis is 10.0% in the study group and 50.0% in the control group, the difference between two groups being statistically significant (P < 0.05). Oral pH values decreased in 90% of the subjects in study group, i.e. mucositis risk was reduced whereas oral pH values remained unchanged or decreased in 86.7% of the subjects in the control group, namely mucositis risk increased. The difference between study and control groups in terms of the change in pH values after chemotherapy was found to be statistically significant (P < 0.05). Our findings have demonstrated that oral cryotherapy makes an important contribution to the protection of oral health by reducing the mucositis score according to patient- and physician-judged mucositis score and by increasing oral pH values. Aggressive cancer therapy places patients at greater risk for oral complications and treatment-related consequences. Unfortunately, prevention and/or treatment of such oral sequelae have often become overlooked as priorities of the treatment team. Effective approaches for the prevention or treatment of oral mucositis have not been standardized, and vary considerably among institutions. Prophylactic measures begin with an increased emphasis on improved oral status. Oral cryotherapy, the therapeutic administration of cold, is a prophylactic measure for oral inflammation. The relevance for clinical practice will be to understand the content of mucositis; comprehensive care should focus on the prevention of this complication in the clinical practice.

The aim of this Stage I Behavioral Development Trial was to develop a manual-based 12-session Women's Recovery Group (WRG) and to pilot test this new treatment in a randomized controlled trial against a mixed-gender Group Drug Counseling (GDC), an effective manual-based treatment for substance use disorders. After initial manual development, two pre-pilot groups of WRG were conducted to determine feasibility and initial acceptability of the treatment among subjects and therapists. In the pilot stage, women were randomized to either WRG or GDC. No significant differences in substance use outcomes were found between WRG and GDC during the 12-week group treatment. However, during the 6-month post-treatment follow-up, WRG members demonstrated a pattern of continued reductions in substance use while GDC women did not. In addition, pilot WRG women with alcohol dependence had significantly greater reductions in average drinks/drinking day than GDC women 6 months post-treatment (p<.03, effect size=0.81). While satisfaction with both groups was high, women were significantly more satisfied with WRG than GDC (p<.009, effect size=1.11). In this study, the newly developed 12-session women-focused WRG was feasible with high satisfaction among participants. It was equally effective as mixed-gender GDC in reducing substance use during the 12-week in-treatment phase, but demonstrated significantly greater improvement in reductions in drug and alcohol use over the post-treatment follow-up phase compared with GDC. A women-focused single-gender group treatment may enhance longer-term clinical outcomes among women with substance use disorders.

Theory-of-Mind (ToM) keeps on developing in late childhood and early adolescence, and the study of ToM development later in childhood had to await the development of sufficiently sensitive tests challenging more mature children. The current study aimed to investigate the psychometric properties of the Danish version of the Theory-of-Mind Storybook Frederik (ToM-Frederik). We assessed whether ToM-Frederik scores differed between a group of 41 typically developing (TD) children and a group of 33 children with High Functioning Autism Spectrum Disorder (HFASD). A lower mean ToM-Frederik score was expected in the HFASD group. To determine the convergent validity of ToM-Frederik, potential associations with Strange Stories and Animated Triangles (AT) were analyzed. Furthermore, potential associations between ToM-Frederik and the Social Responsiveness Scale (SRS) and between ToM-Frederik and the Social Emotional Evaluation (SEE) Total score were analyzed. A significantly higher ToM-Frederik score was observed in the TD group compared to the HFASD group. Furthermore, the convergent validity of ToM-Frederik as a measure of ToM was supported by significant and positive associations with the Strange Stories and the AT scores in the HFASD group, whereas ToM-Frederik was significantly correlated with Strange Stories, but not with AT in the TD group. ToM-Frederik was not significantly associated with SRS in neither the HFASD nor the TD group. The findings are supportive of ToM-Frederik as a valid indicator of deficits at the group level in children with HFASD between 7 and 14 years of age. Furthermore, the convergent validity is supported.

The low incidence and the heterogeneity of very rare tumors (VRTs) demand for international cooperation. In 2008, EXPeRT (European Cooperative Study Group for Pediatric Rare Tumors) was founded by national groups from Italy, France, United Kingdom, Poland and Germany. The first aims of EXPeRT were to agree on a uniform definition of VRTs and to develop the currently most relevant scientific questions. Current initiatives include international data exchange, retrospective and prospective studies of specific entities, and the development of harmonized and internationally recognized guidelines. Moreover, EXPeRT established a network for expert consultation to assist in clinical decision in VRTs. © Georg Thieme Verlag KG Stuttgart · New York.

Reaven, Judy; Blakeley-Smith, Audrey; Culhane-Shelburne, Kathy; Hepburn, Susan

2015-01-01

Background Children with high-functioning autism spectrum disorders (ASD) are at high risk for developing significant anxiety. Anxiety can adversely impact functioning across school, home and community environments. Cognitive behavior therapies (CBT) are frequently used with success for children with anxiety symptoms. Modified CBT interventions for anxiety in children with ASD have also yielded promising results. Methods Fifty children with high-functioning ASD and anxiety were randomized to group CBT or Treatment as Usual (TAU) for 12 weeks. Independent Clinical Evaluators, blind to condition, completed structured interviews (Anxiety Disorders Interview Schedule – Parent Version; ADIS-P) pre- and post-intervention condition. Results Forty-seven children completed either the CBT or TAU condition. Results indicated markedly better outcomes for the CBT group. Significant differences by group were noted in Clinician Severity Ratings, diagnostic status, and clinician ratings of global improvement. In the intent-to-treat sample, ten of 20 children (50%) in the CBT group had a clinically meaningful positive treatment response, compared to 2 of 23 children (8.7%) in the TAU group. Conclusions Initial results from this rigorously designed treatment study suggest that a group CBT intervention specifically developed for children with ASD may be effective in decreasing anxiety. Limitations of this study include small sample size, lack of an attention control group, and use of outcome measures normed with typically developing children. PMID:22435114

This paper aims to develop and analyze the effects of a socio-ecological model-based intervention program for preventing metabolic syndrome (MetS) among office workers. The intervention program was developed using regular health examinations, a “health behavior and need” assessment survey among workers, and a focus group study. According to the type of intervention, subjects took part in three groups: health education via an intranet-based web magazine (Group 1), self-monitoring with the U-health system (Group 2), and the target population who received intensive intervention (Group 3). The intervention programs of Group 1 and Group 2, which relied on voluntary participation, did not show significant effects. In Group 3, which relied on targeted and proactive programs, showed a decrease in waist circumference and in fasting glucose (p < 0.001). The MetS score in both males (−0.61 ± 3.35 versus −2.32 ± 2.55, p = 0.001) and females (−3.99 ± 2.05 versus −5.50 ± 2.19, p = 0.028) also showed a statistically significant decrease. In light of the effectiveness of the intensive intervention strategy for metabolic syndrome prevention among workers used in this study, companies should establish targeted and proactive health care programs rather than providing a healthcare system that is dependent on an individual’s voluntary participation.

Lee, Kathryn Martell

Much of the professional development in the past decades has been single incident experiences. The heart of inservice growth is the sustained development of current knowledge and practices, vital in science education, as reflected in the National Science Education Standards' inquiry and telecommunications components. This study was an exploration of an Internet-delivered professional development experience, utilizing multiple session interactive real-time data sources and semester-long sustained telementoring. Two groups of inservice teachers participated in the study, with only one group receiving a telementored coaching component. Measures of the dependent variable (delivery of an inquiry-based laboratory lesson sequence) were obtained by videotape, and predictive variables (self-analysis of teaching style and content delivery interviews) were administered to the forty veteran secondary school science teacher volunteers. Results showed that teachers in the group receiving semester-long coaching performed significantly better on utilizing the Internet for content research and inquiry-based lesson sequence delivery than the group not receiving the coaching. Members of the coached group were able to select a dedicated listserv, e-mail, chatline or telephone as the medium of coaching. While the members of the coached group used the listserv, the overwhelming preference was to be coached via the telephone. Qualitative analysis indicated that the telephone was selected for its efficiency of time, immediacy of response, and richer dialogue. Perceived barriers to the implementation of the Internet as a real-time data source in science classrooms included time for access, obsolesce of equipment, and logistics of computer to student ratios. These findings suggest that the group of science teachers studied (1) benefited from a sustained coaching experience for inquiry-based lesson delivery, (2) perceived the Internet as a source of content for their curriculum rather than a communication source, and (3) preferred the telephone as a coaching tool for its efficiency and convenience. Utilizing current pedagogy in science and telecommunication tools has served to whet the appetite of the study teachers to develop utilization of the Internet in their classes for real-time data acquisition.

The aim of the study The aim of the study was to determine whether there are any differences in the intima-media thickness (IMT) of carotid arteries between the group of patients with systemic lupus erythematosus (SLE) and the control group, and whether these differences are a consequence of SLE or independent factors of atherosclerosis development. Material and methods The patients were divided into three groups: the study group (n = 25, mean age: 39.8 years) consisting of patients suffering from SLE; the subgroup (n = 13, mean age: 39.2 years) consisting of patients suffering only from SLE without any accompanying diseases; and the control group (n = 25, mean age: 37.1 years) consisting of healthy patients (not suffering from SLE or any other disease of the connective tissue). The IMT of the left and right common carotid arteries (LCCA, RCCA) was measured by means of ultrasound. Results The analysis performed with the Mann-Whitney U test showed that a statistically significant difference of IMT occurs between the control group and the study groups (p = 0.006 for LCCA and p < 0.001 for RCCA), while there is no such relation (p = 0.86 for RCCA and p = 0.095 for LCCA) between the control group and the subgroup. Conclusions The group of patients with SLE was found to have an increased IMT in comparison with the reference group. The unfavorable influence of independent factors of atherosclerosis development on the increase of the IMT value in patients with lupus was thus indicated. This observation suggests a faster atherosclerotic process in this group of patients. PMID:26336397

Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic hepatitis, which leads to cirrhosis and hepatocellular carcinoma. However, it is difficult to identify subjects at high risk for NAFLD onset. This study aims to construct a model to predict the onset of NAFLD within 2 years in elderly adults. This study included and followed 3378 initial NAFLD-free subjects aged 60 years or over for 2 years, which were randomly divided into a training set and a validation set. NAFLD was diagnosed on ultrasound. Clinical and laboratory data were recorded at baseline. A model was constructed in the training set to predict the onset of NAFLD and validated in the validation set. Body mass index, hemoglobin, fasting blood glucose, and triglycerides were identified as predictors for the onset of NAFLD. A risk score (R) was calculated by them. It classified the subjects into low-risk group (R ≤ -2.88), moderate-risk group (-2.88 < R ≤ -1.26), and high-risk group (R > -1.26). In the training set, 4.68% of the participants in the low-risk group, 11.59% of the participants in the moderate-risk group, and 31.02% of the participants in the high-risk group developed NAFLD. In the validation set, 5.84% of the participants in the low-risk group, 10.57% of the participants in the moderate-risk group, and 29.44% of the participants in the high-risk group developed NAFLD. This study developed a model to predict the onset of NAFLD in elderly adults, which might provide indications for intervention to these subjects. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

To develop/validate an instrument to measure health-related quality of life (HRQoL) in patients with psoriatic arthritis (PsA), for use in clinical studies. An item pool of 35 items was generated following standardized procedures. Item reduction was performed using clinimetric and psychometric approaches after administration to 66 patients with PsA. The resulting instrument, the VITACORA-19, consists of 19 items. Its validity content, internal consistency, test-retest reliability, known groups/convergent validity, and sensitivity to change were tested in a longitudinal and multicenter study conducted in 10 hospitals in Spain, with 323 patients who also completed the EuroQol 5-dimensional questionnaire (EQ-5D) and a health status transition item. There were 3 study groups: group A (n = 209, patients with PsA), group B (n = 71, patients with arthritis without psoriatic aspect, patients with arthrosis, and patients with dermatitis), and group C (n = 43, healthy controls). The questionnaire was considered easy/very easy to answer by 94.7% of the patients with PsA. The factorial analysis clearly identified only 1 factor. Cronbach's alpha coefficient and interclass correlation coefficients exceeded 0.90. Statistically significant differences (p < 0.001) were observed between groups: subjects from group C had better HRQoL, followed by group B, and finally group A had the worst HRQoL. The VITACORA-19 scores showed significant correlations (p < 0.001) to PsA disease activity, EQ-5D, and perceived health state, scoring the patients with better health state higher. The minimum important difference was established as an 8-point change in the global score. The Spanish-developed VITACORA-19, designed to measure HRQoL in patients with PsA, has good validity, reliability, and sensitivity to change.

Identifying the housing preferences of people with complex disabilities is a much needed, but under-developed area of practice and scholarship. Despite the recognition that housing is a social determinant of health and quality of life, there is an absence of empirical methodologies that can practically and systematically involve consumers in this complex service delivery and housing design market. A rigorous process for making effective and consistent development decisions is needed to ensure resources are used effectively and the needs of consumers with complex disability are properly met. This 3-year project aims to identify how the public and private housing market in Australia can better respond to the needs of people with complex disabilities whilst simultaneously achieving key corporate objectives. First, using the Customer Relationship Management framework, qualitative (Nominal Group Technique) and quantitative (Discrete Choice Experiment) methods will be used to quantify the housing preferences of consumers and their carers. A systematic mixed-method, quasi-experimental design will then be used to quantify the development priorities of other key stakeholders (e.g., architects, developers, Government housing services etc.) in relation to inclusive housing for people with complex disabilities. Stakeholders randomly assigned to Group 1 (experimental group) will participate in a series of focus groups employing Analytical Hierarchical Process (AHP) methodology. Stakeholders randomly assigned to Group 2 (control group) will participate in focus groups employing existing decision making processes to inclusive housing development (e.g., Risk, Opportunity, Cost, Benefit considerations). Using comparative stakeholder analysis, this research design will enable the AHP methodology (a proposed tool to guide inclusive housing development decisions) to be tested. It is anticipated that the findings of this study will enable stakeholders to incorporate consumer housing preferences into commercial decisions. Housing designers and developers will benefit from the creation of a parsimonious set of consumer-led housing preferences by which to make informed investments in future housing and contribute to future housing policy. The research design has not been applied in the Australian research context or elsewhere, and will provide a much needed blueprint for market investment to develop viable, consumer directed inclusive housing options for people with complex disability.

The study conducted in a bacterial-based in vitro caries model aimed to determine whether typical inner secondary caries lesions can be detected at cavity walls of restorations with selected gap widths when the development of outer lesions is inhibited. Sixty bovine tooth specimens were randomly assigned to the following groups: test group 50 (TG50; gap, 50 microm), test group 100 (TG100; gap, 100 microm), test group 250 (TG250; gap, 250 microm) and a control group (CG; gap, 250 microm). The outer tooth surface of the test group specimens was covered with an acid-resistant varnish to inhibit the development of an outer caries lesion. After incubation in the caries model, the area of demineralization at the cavity wall was determined by confocal laser scanning microscopy. All test group specimens demonstrated only wall lesions. The CG specimens developed outer and wall lesions. The TG250 specimens showed significantly less wall lesion area compared to the CG (p < 0.05). In the test groups, a statistically significant increase (p < 0.05) in lesion area could be detected in enamel between TG50 and TG250 and in dentine between TG50 and TG100. In conclusion, the inner wall lesions of secondary caries can develop without the presence of outer lesions and therefore can be regarded as an entity on their own. The extent of independently developed wall lesions increased with gap width in the present setting.

The study aims to describe receptive language skills in children with intellectual disability (ID) and to contribute to the debate on deviant versus delayed language development. This is the 1st study of receptive skills in children with ID who speak a Slavic language, providing insight into how language development is affected by disability and also language typology. Twenty-eight Slovak-speaking children participated in the study (14 children with ID and 14 typically developing [TD] children matched on nonverbal reasoning abilities). The children were assessed by receptive language tasks targeting words, sentences, and stories, and the groups were compared quantitatively and qualitatively. The groups showed similar language profiles, with a better understanding of words, followed by sentences, with the poorest comprehension for stories. Nouns were comprehended better than verbs; sentence constructions also showed a qualitatively similar picture, although some dissimilarities emerged. Verb comprehension was strongly related to sentence comprehension in both groups and related to story comprehension in the TD group only. The findings appear to support the view that receptive language skills follow the same developmental route in children with ID as seen in younger TD children, suggesting that language development is a robust process and does not seem to be differentially affected by ID even when delayed.

To check the effectiveness of a mindfulness development meditation technique on stress and anxiety in a group of primary-care physicians. Quasi-experimental with pretest/posttest/follow-up measurements in a control group and an experimental group. SITE: University of Almeria. 38 primary-care physicians enrolled in a Teaching Aptitude Course (CAP). An experimental group and a control group were formed with 19 participants in each. The experimental group took a psycho-educational meditation program for training and practice in mindfulness. The Perceived Stress Scale (PSS), the Strain Questionnaire and the State-Trait Anxiety Questionnaire were used to measure stress and anxiety levels. A comparative statistical analysis was performed using the Mann-Whitney non-parametric U test, finding a significant reduction in all the primary-care physician stress and anxiety variables in the experimental group compared to the control group in pretest-posttest and follow-up tests. The results of this study support the effectiveness of mindfulness development meditation techniques in decreasing stress and anxiety in primary-care physicians. Nevertheless, the study shows various limitations that would have to be corrected in successive studies to bring more validity to the results. Copyright © 2009 Elsevier España, S.L.

MicroRNAs are non-coding RNAs that regulate gene expression including differentiation and development by either inhibiting translation or inducing target degradation. The aim of this study is to determine the microRNA expression signature during human pancreatic development and to identify potential microRNA gene targets calculating correlations between the signature microRNAs and their corresponding mRNA targets, predicted by bioinformatics, in genome-wide RNA microarray study. The microRNA signature of human fetal pancreatic samples 10-22 weeks of gestational age (wga), was obtained by PCR-based high throughput screening with Taqman Low Density Arrays. This method led to identification of 212 microRNAs. The microRNAs were classified in 3 groups: Group number I contains 4 microRNAs with the increasing profile; II, 35 microRNAs with decreasing profile and III with 173 microRNAs, which remain unchanged. We calculated Pearson correlations between the expression profile of microRNAs and target mRNAs, predicted by TargetScan 5.1 and miRBase algorithms, using genome-wide mRNA expression data. Group I correlated with the decreasing expression of 142 target mRNAs and Group II with the increasing expression of 876 target mRNAs. Most microRNAs correlate with multiple targets, just as mRNAs are targeted by multiple microRNAs. Among the identified targets are the genes and transcription factors known to play an essential role in pancreatic development. We have determined specific groups of microRNAs in human fetal pancreas that change the degree of their expression throughout the development. A negative correlative analysis suggests an intertwined network of microRNAs and mRNAs collaborating with each other. This study provides information leading to potential two-way level of combinatorial control regulating gene expression through microRNAs targeting multiple mRNAs and, conversely, target mRNAs regulated in parallel by other microRNAs as well. This study may further the understanding of gene expression regulation in the human developing pancreas.

Group I correlated with the decreasing expression of 142 target mRNAs and Group II with the increasing expression of 876 target mRNAs. Most microRNAs correlate with multiple targets, just as mRNAs are targeted by multiple microRNAs. Among the identified targets are the genes and transcription factors known to play an essential role in pancreatic development. Conclusions We have determined specific groups of microRNAs in human fetal pancreas that change the degree of their expression throughout the development. A negative correlative analysis suggests an intertwined network of microRNAs and mRNAs collaborating with each other. This study provides information leading to potential two-way level of combinatorial control regulating gene expression through microRNAs targeting multiple mRNAs and, conversely, target mRNAs regulated in parallel by other microRNAs as well. This study may further the understanding of gene expression regulation in the human developing pancreas. PMID:20860821

Informal music activities such as singing may lead to augmented auditory perception and attention. In order to study the accuracy and development of music-related sound change detection in children with cochlear implants (CIs) and normal hearing (NH) aged 4–13 years, we recorded their auditory event-related potentials twice (at T1 and T2, 14–17 months apart). We compared their MMN (preattentive discrimination) and P3a (attention toward salient sounds) to changes in piano tone pitch, timbre, duration, and gaps. Of particular interest was to determine whether singing can facilitate auditory perception and attention of CI children. It was found that, compared to the NH group, the CI group had smaller and later timbre P3a and later pitch P3a, implying degraded discrimination and attention shift. Duration MMN became larger from T1 to T2 only in the NH group. The development of response patterns for duration and gap changes were not similar in the CI and NH groups. Importantly, CI singers had enhanced or rapidly developing P3a or P3a-like responses over all change types. In contrast, CI non-singers had rapidly enlarging pitch MMN without enlargement of P3a, and their timbre P3a became smaller and later over time. These novel results show interplay between MMN, P3a, brain development, cochlear implantation, and singing. They imply an augmented development of neural networks for attention and more accurate neural discrimination associated with singing. In future studies, differential development of P3a between CI and NH children should be taken into account in comparisons of these groups. Moreover, further studies are needed to assess whether singing enhances auditory perception and attention of children with CIs. PMID:25540628

In a field study (148 participants organized in 38 groups) we tested the effect of group synergy and one's position in relation to the collaborative zone of proximal development (CZPD) on the change of individual decision-making competencies. We used two parallel sets of decision tasks reported in previous research to test rationality and we evaluated individual decision-making competencies in the pre-group and post-group conditions as well as group rationality (as an emergent group level phenomenon). We used multilevel modeling to analyze the data and the results showed that members of synergetic groups had a higher cognitive gain as compared to members of non-synergetic groups, while highly rational members (members above the CZPD) had lower cognitive gains compared to less rational group members (members situated below the CZPD). These insights extend the literature on group-to-individual transfer of learning and have important practical implications as they show that group dynamics influence the development of individual decision-making competencies.

Of 640 women who paid their first visit to the two maternal welfare centres in a new Stockholm suburb during one prospective year, 532 (85%) were interviewed with regard to 41 stress factors forming a "life stress score" (LSS). The interviews were supplemented with data from hospital, social welfare and police records concerning the expectant mother and the father. The 532 mothers were divided into three groups according to the degree of psychosocial stress (group 1 (n = 194) without psychosocial stress; group 2 (n = 171) with severe psychosocial stress; and group 3 (n = 167) in an intermediate group). In group 2, there were 23 mothers and 51 fathers in 64 families known to suffer from alcoholism/heavy drinking at the time of the first interview and these comprised our study group. The pregnancies and deliveries in the families were investigated with prospective methods. There were 497 liveborn children of whom 54 were born into families known for alcoholism/heavy drinking. The physical health and development of the children was followed by prospective data from the child welfare centers. Data concerning psychological development and psychiatric health of the child were obtained by interviewing the mother and evaluating the child during visits at home at one and four years of age. At one year of age, 452 of the children (226 boys, 226 girls) and at four to five years of age, 412 of the children (202 boys, 210 girls), were evaluated using the Griffiths' Development Scales. Findings from these evaluations form the basis for comparison of development of children from alcoholic/heavy drinking parents with all other children. For 388 children, data were available from all examinations up to the end of the fourth year, including 38 children (12 boys, 26 girls) in the study group and 350 other children (183 boys, 167 girls). The present findings indicate that children of alcoholic parents in the general population who were followed from pregnancy up to the end of their fourth year have a higher risk of pre- and postnatal death, and have poorer mental development and more symptoms of a psychopathological child psychiatric nature (DSM-III) than other children. Differences related to physical development during infant years disappeared during the observation time. With regard to mental development over a longer period, it appears that factors related to the parent's addictions and the child's sex (i.e. male child) are more important than pediatric risk factors in the form of a score of reduced optimality.

Is the Preoperative Administration of Amiodarone or Metoprolol More Effective in Reducing Atrial Fibrillation: After Coronary Bypass Surgery?

PubMed

Onk, Oruc Alper; Erkut, Bilgehan

2015-10-01

This study examined the influence of preoperative administration of amiodarone and metoprolol in preventing postoperative atrial fibrillation (AF) after coronary artery bypass grafting (CABG) surgery.The study comprised 251 patients who underwent CABG surgery at our hospital between January 2012 and May 2014. The patients were randomly divided into 2 groups: amiodarone therapy group (n = 122 patients) and metoprolol therapy group (n = 129 patients).In the amiodarone group, the patients received amiodarone tablet orally 1 week before coronary bypass surgery and during the postoperative period. In the metoprolol group, the patients received metoprolol tablet orally 1 week before surgery and during the postoperative period. The AF development rate was retrospectively evaluated between the first 3 days and 4 weeks after surgery.AF developed in 14 patients in the amiodarone group and 16 patients in the metoprolol group 4 weeks after the operation (P = 0.612).No significant difference was observed between the groups in terms of intensive care unit and hospital stay. Furthermore, hospital charges were similar in both groups (P = 0.741).The results of the logistic regression analysis showed age, left ventricular ejection fraction, left atrial diameter, and aortic cross-clamping time to be predictors for postoperative AF.This study demonstrates that amiodarone and metoprolol have similar effects in prevention of AF after cardiac surgery. However, larger-scale studies need to be conducted to substantiate these findings.

Introduction This study aims to explore the impact of Parent Participation Program on the development of developmental delay children. Methods Pretest-posttest equivalent-group experimental design study was used in this paper. A total of 30 pairs of developmental delay children aged 0–72 months and their parents participated into this study. They were divided into two groups, namely control group and experimental group, according to parents’ wishes. The objects of study in control group received 16 courses of direct rehabilitation therapy; those in experimental group received 8 courses of direct rehabilitation therapy and 8 courses of instruction and tracking of Parent Participation Program. The duration of the intervention was 8 weeks. All cases should be evaluated before and after the intervention, to analyze the difference before and after intervention and among groups. The statistical methods in this paper included descriptive analysis, Chi-square test, independent sample t-test, pair-sample t-test. Results and conclusion The intervention of Parent Participation Occupational Program has positive impact on the development of developmental delay children in various fields. Among all the intervention results, the progress of the experimental group is 1.895 times more than that of the control group. With parent involvement, Parent Participation Occupational Therapy can promote the cognitive ability, language ability, action ability (gross and fine movement), social competence and self-care ability of children with developmental delay. Finally, the researcher presents suggestions and directions for future research in accordance with the results. PMID:29503546

2017-04-01

The Health Education for Persons with Multiple Sclerosis (HEMS) program was developed in response to the need for interventions aimed at increasing physical activity for individuals with Multiple Sclerosis (MS). It was developed and evaluated using Drum and colleagues (2009) guidelines for implementing health promotion programs for individuals with disabilities. The purpose of this feasibility study is to describe the development, implementation, and evaluation of the HEMS program. Thirteen individuals with MS completed the 8-week health education program. A mixed method approach for evaluation was implemented (i.e., survey and focus groups). Process and resource feasibility demonstrated that over half of the participants attended at least 80% of the weekly sessions. Focus group data provided valuable feedback for future iterations of the program including critiques on the delivery, content, and group support provided. Outcome evaluation showed increases in self-efficacy (survey), improvements in theoretical constructs (focus groups), and increased physical activity (focus groups). Results show that health promotion programs for persons with MS can improve physical activity and related constructs. Next steps will be to revise, implement, and reevaluate the HEMS program in a larger randomized control trial. Published by Elsevier Ltd.

A better understanding of the developmental problems in extremely low birth weight (ELBW) preterm infants may enhance their chances of proper adaptation to their environment and make it possible to retrospectively assess perinatal and neonatal methods of treatment. The aim of the study was to evaluate the cognitive and motor development of ELBW children born from 2002 to 2004 in the 7th year of life. Based on these results and perinatal mortality data, it was established what chance the children have to live free of severe complications. Two hundred and four alive newborns with birth weight .1000 g were born in the Malopolska voivodship between 1.09.2002 and 31.08.2004. One hundred and fifteen children (56%) died in early infancy. The study included 81 (91%) children out of the 89 surviving ones. Their mean gestational age at birth was 27.3 weeks. (SD: 2.1 weeks) and their mean birth weight was 840g (SD: 130g). Neurosensory disturbances were assessed in all the children and their cognitive development was evaluated with the use of the WISC-R (Wechsler Intelligence Scale for Children . Revised) scale. The children were divided into 3 groups: group I . normal development (full motor capacity and IQ >84 points and no vision or hearing impairment), group II . mild or moderate impairment (cerebral palsy level I, II or III according to the Gross Motor Function Classification System [GMCS], or IQ 40-84 points, or abnormal vision or hearing, or signs of the hyperactivity syndrome), group III . severe impairment (cerebral palsy level IV, and/or IQ <40 points, or deafness/blindness). Forty-five (56%) children were included in group I, 25 (30%) in group II and 11 (14%) in group III. Moreover, other neurologic abnormalities, such as uneven development, problems with concentration, or abnormal grapho-motor ability were highly prevalent in the group of ELBW children. The incidence of cerebral palsy in the population studied was 16%, the incidence of deafness and severe hearing impairment was 11%, and blindness and severe vision impairment . 12%. In general, the chance of survival free of severe complications was merely 15% in children with birthweight .700 g, 28% in children with birth weight 701- 800 g, 45% in children with birth weight 801-900 g, and 62% in children with birth weight 901-1000 g. 1. The data gathered in a regional study may yield valuable information useful in assessing the prognosis of the general health status of ELBW newborns. 2. Most of the children present uneven development, problems with concentration, or abnormal grapho-motor ability, which may be a cause of learning problems and abnormal relationships with peers. 3. A follow-up study up to adulthood is required for this group of ELBW newborns.

To test the hypothesis that acute inflammatory reaction associates with the development of pressure ulcers in bedridden elderly patients, 40 hospitalized elderly patients suffering from bacterial pneumonia, cerebrovascular disease, and femoral bone fracture were enrolled in this study. All of them were divided into two groups with pressure ulcers (group P; 17 patients) and without one (group N; 23 patients). The blood samples were taken from them within 5 days after the patients being bedridden. Although no significant difference exist in pressure ulcer risk factors (age, gender, Braden scale, underlying diseases, blood pressure, and heart rate) between the two groups, white blood cell, plasma C-reactive protein and fibrinogen in group P increased significantly as compared with those in group N. Besides number of platelets and maximum platelet aggregation rate were significantly higher in group P than in group N. Serum albumin and hemoglobin of both groups decreased after being bedridden, especially hemoglobin in group P was significantly lower than that in group N. While the concentration of serum IL-6 did not indicate a significant difference between both the groups, serum IL-1 beta increased significantly in group P. In conclusion, we suggested that acute inflammatory reaction releasing proinflammatory cytokines affected the development of pressure ulcer in bedridden elderly patients.

This study examined the problems encountered by children with autism spectrum disorder (ASD), when accessing dental care. This was a cross-sectional, case-control questionnaire study. A piloted questionnaire was developed to identify the main barriers to dental care experienced by patients with ASD in Hull and East Riding. The study group was comprised of parents/carers of children with ASD, and the control group was comprised of parents/carers of age matched healthy, neurotypical children. Results were analysed using Chi-square and Fisher's exact tests where appropriate. Significance was deemed at p < 0.05. Ordinal data was presented using medians and 25th and 75th centiles and compared using Mann-Whitney U test. A piloted questionnaire was developed to identify the main barriers to dental care experienced by patients with ASD in Hull and East Riding. The study group was comprised of parents/carers of children with ASD, and the control group was comprised of parents/carers of age matched healthy, neurotypical children. 112 subjects completed the questionnaire. There was no significant difference in accessing dental care between study and control groups (p = 0.051), although access was perceived as more difficult in the ASD group (p < 0.001). There was a significantly greater perceived difficulty in travelling to the dental surgery in the ASD group. Predicted negative behaviours were more frequent in the ASD group. All suggested interventions were predicted to be helpful in a significantly greater proportion of the ASD group. Difficulties exist for children with ASD in accessing dental care in the Hull and East Riding area.

This study was conducted to compare the level of depression, self-esteem and mother-adolescent (M-A) communication perceived by both mothers and adolescents between the early adolescent (E-A) group and the late adolescent (L-A) group; and to examine the actor effect and the partner effect of self-esteem and M-A communication on depression in mothers and adolescents. Participants were 107 Kirogi families who resided in the Midwest region of the U. S. Data were collected from September, 2008 to March, 2009 using the scales of Center for Epidemiologic Studies Depression (CES-D), Self-esteem and Parent-Adolescent Communication Inventory. Mothers in E-A group reported higher scores on depression than mothers in L-A group. Adolescents in L-A group reported higher scores on depression and lower scores on self-esteem than adolescents in E-A group. In the E-A group, mothers' self-esteem had big actor effect on mothers' depression and partner effect on adolescents' depression. In the L-A group, self-esteem of mothers and adolescents had actor effect on their depression respectively without partner effect. M-A communication of mothers influences mothers' depression negatively and adolescents' depression positively. In both group, M-A communication influences their depression with mediating effect of self-esteem. To promote Kirogi families' mental health, programs for mothers and adolescents should be developed differently according to adolescents' development stage.

Diabetes mellitus is one of the serious global health problems affecting a significant proportion of both developed and developing countries. Overproduction of free radicals and oxidative stress has been associated with the development of diabetic complications. In the present study, the antioxidant effects of metformin (MET), glibenclamide (GLI), and repaglinide (REP) were evaluated in alloxan-induced diabetic rats. The findings from this study may possibly help in understanding the efficacy of these standard drugs in managing the complications arising from diabetes mellitus (DM). Alloxan (130 mg/kg BW) was administered as a single dose to induce diabetes. Four (4) groups of rats (n = 6) were used; group 1 served as diabetic control while groups 2, 3, and 4 were the diabetic test groups that received MET (25 mg/kg), GLI (2.5 mg/kg), and REP (0.5 mg/kg), respectively. The result of the study showed significant (p < 0.05) improvement in the altered antioxidant enzymes (SOD, CAT) and GSH concentration in diabetic treated rats compared with the diabetic control group. MET and REP produced significant effect on the MDA concentration while GLI showed insignificant reduction in the MDA concentration compared with the diabetic control. Findings from this study suggest that the administration of MET, GLI, and REP exerts significant antioxidant effects in alloxan-induced diabetic rats, thus contributing to the protective effect against oxidative stress-induced damage during diabetic complications.

Harwood, Irene

2006-01-01

In this paper new knowledge generated from theoretical and empirical work in infant observation studies and attachment, trauma, and neurobiology research is integrated and applied to the development of a group for pregnant and new mothers. The purposes of this group were to (1) promote the establishment of a secure base for each baby through optimum self and dyadic affect regulation, the repair of ruptures, and the emergence of positive heightened affective moments; (2) to facilitate secure attachment between mother and infant by helping mothers mentalize the experiences of their babies; (3) to build affiliative bonds between group members and; at the very least, (4) to prevent insecure disorganized attachments. The group interactions also were thought to prevent new psychopathology from developing, as well as to minimize the intergenerational transmission of trauma. A discussion of how this group came out of gestation and birthed itself in a community setting is included.

Immunosuppressive treatment used in pregnant liver recipients may have a negative impact on fetal development and successively a child. The aim of the study was to make a neurological assessment of infants and children born to liver transplant recipients (LTRs) born between December 4, 2001, and February 11, 2013, in the 1(st) Department of Obstetrics and Gynecology, Medical University of Warsaw. The study involved 88 children, of whom 44 children were born to LTR mothers, and 44 children born to women who were not organ recipients and delivered at a similar gestational age. The gestational age of neonates ranged from 33 to 41 weeks, and the birth weight ranged from 1420 g to 4100 g. The neurological examination was performed in children from 7 weeks to 10 years of age. The neurological development was assessed by a specialist in pediatric neurology. The results of the examination were divided according to the following criteria: 1) normal development, 2) slight disorders, 3) moderate disorders, and 4) severe disorders. The Fisher's exact test was used for statistical analysis. Normal development was found in 35 of 44 (79.54%) children in the LTR group and 39 of 44 (88.63%) children in the control group (P = .3827). Slight disorders were observed in 6 of 44 (13.63%) children in LTR group and 5 of 44 (11.36%) children in the control group. Moderate disorders were found only in 3 of 44 (6.81%) children in the LTR group. No severe disorders were observed in both groups. Neurological development of children born to the liver recipients who were exposed to chronic immunosuppressive treatment in their fetal lives is the same as that of children whose mothers have not undergone organ transplantation.

Minimal groups increase young children's motivation and learning on group-relevant tasks.

PubMed

Master, Allison; Walton, Gregory M

2013-01-01

Three experiments (N = 130) used a minimal group manipulation to show that just perceived membership in a social group boosts young children's motivation for and learning from group-relevant tasks. In Experiment 1, 4-year-old children assigned to a minimal "puzzles group" persisted longer on a challenging puzzle than children identified as the "puzzles child" or children in a control condition. Experiment 2 showed that this boost in motivation occurred only when the group was associated with the task. In Experiment 3, children assigned to a minimal group associated with word learning learned more words than children assigned an analogous individual identity. The studies demonstrate that fostering shared motivations may be a powerful means by which to shape young children's academic outcomes. © 2012 The Authors.

PubMed

Wang, Z M

1994-07-01

An experimental programme of group attributional training under team work system was conducted as part of human resource development in Chinese industrial enterprises. One hundred and ten shopfloor employees participated in the study. Among them, 58 employees took part in the factorial-designed experiment to find out the effects of attributions on performance, and 52 employees of ten work groups participated in the group attributional training programme twice a week for two months. The results showed that the group attributional training was effective in modifying employees' attributional patterns and enhancing group performance and satisfaction. On the basis of the results, an attributional model of work motivation is proposed, and its theoretical and practical implications for human resource management discussed.

Executive function and play skills develop in early childhood and are linked to cognitive and language ability. The present study examined these abilities longitudinally in two groups with autism spectrum disorder-a group with higher initial language (n = 30) and a group with lower initial language ability (n = 36). Among the lower language group, concurrent nonverbal cognitive ability contributed most to individual differences in executive function and play skills. For the higher language group, executive function during preschool significantly predicted play ability at age 6 over and above intelligence, but early play did not predict later executive function. These results suggested that factors related to the development of play and executive function differ for subgroups of children with different language abilities and that early executive function skills may be critical in order for verbal children with autism to develop play.

We determined optimal fasting plasma glucose (FPG) cutoff values predictive of future diabetes development in a group of middle-aged Koreans who visited a health promotion center. The medical records of 2,964 subjects, who attended the Health Promotion Center in 1998 and 2003, were examined. Subjects were classified into four groups according to their baseline FPG values (Group 1:FPG <5.0 mM/L; Group 2: 5.0< or =FPG <5.6 mM/L; Group 3: 5.6< or =FPG <6.1 mM/L; Group 4: 6.1< or =FPG <7.0 mM/L). No significant difference was observed between Group 1 and Group 2 in terms of diabetes incidence. However, incidence in Group 3 was significantly higher than that in Group 1 [hazards ratio 4.88 (1.65-14.41), p=0.004] and the hazards ratio in Group 4 for diabetes was 36.91 (13.11-103.61), p<0.001, versus Group 1. Receiver operator characteristics curve analysis showed that an FPG of 5.97 mM/L represents the lower limit and gives the best combination of sensitivity and specificity. Our data shows that the risk of future diabetes development started to increase below an FPG of 6.1 mM/L and suggests the importance of efforts to modify diabetes development risk factors at lower impaired fasting glucose levels.

Over the course of childhood, children's thinking about social groups changes in a variety of ways. Developmental Subjective Group Dynamics (DSGD) theory emphasizes children's understanding of the importance of conforming to group norms. Abrams et al.'s study, which uses DSGD theory as a framework, demonstrates the social cognitive skills underlying young elementary school children's thinking about group norms. Future research on children's thinking about groups and group norms should explore additional elements of this topic, including aspects of typicality beyond loyalty. © 2014 The British Psychological Society.

To integrate multiple sources of clinical information with patient feedback to build evidence-based decision support model to facilitate treatment selection for patients suffering from vestibular schwannomas (VS). This was a mixed methods study utilizing focus group and survey methodology to solicit feedback on factors important for making treatment decisions among patients. Two 90-minute focus groups were conducted by an experienced facilitator. Previously diagnosed VS patients were recruited by clinical investigators at the University of Pittsburgh Medical Center (UPMC). Classical content analysis was used for focus group data analysis. Providers were recruited from practices within the UPMC system and were surveyed using Delphi methods. This information can provide a basis for multi-criteria decision analysis (MCDA) framework to develop a treatment decision support system for patients with VS. Eight themes were derived from these data (focus group + surveys): doctor/health care system, side effects, effectiveness of treatment, anxiety, mortality, family/other people, quality of life, and post-operative symptoms. These data, as well as feedback from physicians were utilized in building a multi-criteria decision model. The study illustrated steps involved in the development of a decision support model that integrates evidence-based data and patient values to select treatment alternatives. Studies focusing on the actual development of the decision support technology for this group of patients are needed, as decisions are highly multifactorial. Such tools have the potential to improve decision making for complex medical problems with alternate treatment pathways. Copyright © 2016 Elsevier Inc. All rights reserved.

The use of social marketing approaches in public health practice is increasing. Using marketing concepts such as the "four Ps" (product, price, place, and promotion), social marketing borrows from the principles of commercial marketing but promotes beneficial health behaviors. Consumer research is used to segment the population and develop a strategy based on those marketing concepts. In a community-based participatory research study, 17 focus groups were used in consumer research to develop a social marketing program to promote walking and other moderate-intensity physical activities. Two phases of focus groups were conducted. Phase 1 groups, which included both men and women, were asked to respond to questions that would guide the development of a social marketing program based on social marketing concepts. Phase 1 also determined the intervention's target audience, which was irregularly active women aged 35 to 54. Phase 2 groups, composed of members of the target audience, were asked to further define the product and discuss specific promotion strategies. Phase 1 participants determined that the program product, or target behavior, should be walking. In addition, they identified price, place, and promotion strategies. Phase 2 participants determined that moderate-intensity physical activity is best promoted using the term exercise and offered suggestions for marketing walking, or exercise, to the target audience. There have been few published studies of social marketing campaigns to promote physical activity. In this study, focus groups were key to understanding the target audience in a way that would not have been accomplished with quantitative data alone. The group discussions generated important insights into values and motivations that affect consumers' decisions to adopt a product or behavior. The focus group results guided the development of a social marketing program to promote physical activity in the target audience in Sumter County, South Carolina.

In extremity soft tissue sarcoma (ESTS), external beam radiotherapy (EBRT) has been used in addition to limb-sparing surgery (LSS). This study aims to identify predictors for major wound complication (MWC) development following EBRT and LSS in ESTS. This retrospective study includes ESTS patients treated with EBRT and LSS between 2005 and 2017. Two groups were formed; Group I included preoperatively irradiated patients, whereas Group II included patients who underwent postoperative EBRT. Multivariate logistic regression analyses were performed to create a prediction model for MWC development. One hundred twenty-seven patients were included, 58 patients (45.7%) in Group I and 69 patients (54.3%) in Group II. Some differences in baseline characteristics were found between the groups, e.g. in tumor size and grade, histological subtype and total RT dose. Twenty-three patients (39.7%) in Group I and 14 patients (20.3%) in Group II developed a MWC (p = 0.02). Preoperative EBRT was identified as independent predictor for MWC development, OR 2.75 (95%CI 1.21-6.26), p = 0.02. Furthermore, a trend towards an increased MWC risk was shown for patients' age (OR 1.02 (0.99-1.04)), delayed wound closure (OR 3.20 (0.64-16.02)) and negative surgical margins (OR 2.26 (0.72-7.11)). The area under the curve (AUC) of the model was 0.68 (0.57-0.79). This study corroborates the increased MWC risk following preoperative EBRT in ESTS. It remains important to carefully weigh the MWC risk against the expected long-term functional outcome, and to consider the liberal use of primary plastic surgical reconstructions in an individualized multidisciplinary tumor board prior to treatment.

The purpose of this study was to investigate the mechanism of dibutyl phthalate (DBP) induced hypospadias and shortened anogenital distance (AGD). AGD, hypospadias, and cryptorchidism incidence was observed in male offspring of DBP treated pregnant Wistar rats. Testicular development and testosterone levels of normal and DBP-treated rat embryos were compared. Male offspring of 300mg and 900mg DBP-treated pregnant Wistar rats exhibited shortened average AGD compared with the control group. A 22.7% hypospadias incidence was observed in the 300mg group, but no offspring with cryptorchidism were identified. In the 900mg group, hypospadias and cryptorchidism incidence reached 43.5% and 17.4%, respectively. Between E15.5 and E17.5, the 300mg group exhibited delayed testicular development and testosterone secretion. However, testicular development and testosterone secretion subsequently recovered. The 300mg treated and control groups had similar measures after E19.5. Contrastingly, testicular development and testosterone secretion were significantly diminished throughout development in the 900mg group. Exogenous testosterone partially counteracted DBP-induced changes in the reproductive organs of male offspring of DBP-treated rats. High-dose DBP exposure may induce testicular dysgenesis in rat embryos. Additionally, low-dose DBP may delay testicular development and testosterone secretion during urethral development. This disruption may result in hypospadias. Copyright © 2015 Elsevier Inc. All rights reserved.

The present study aimed to compare the effects of bacterial cellulose used for closure of pharyngocutaneous fistulae, a complication of total laryngectomy, with those of primary sutures in a rat model. Thirty female Sprague-Dawley underwent experimental pharyngoesophagotomy and were grouped depending on the material used for pharyngocutaneous fistula closure: group I, which received primary sutures alone, group II, which received bacterial cellulose alone; and group III, which received both. After 7 days, the rats were sacrificed. Pharyngocutaneous fistula development was assessed, the gross wound was inspected, and histological examination was conducted. Pharyngocutaneous fistulae developed in 12 rats (41%) in all: 6 from group I (21%), 4 from group II (14%) and 2 from group III (7%). Fibroblast density and inflammatory cell infiltration were significantly greater in group III than group I. We concluded that bacterial cellulose may be useful for pharyngocutaneous fistula closure.

In the present study, oocytes retrieved from cross bred Karan Fries cows by ovum pick-up technique were graded into Group 1 and Group 2, based on the morphological appearance of the individual cumulus-oocyte complexes (COCs). To analyze whether the developmental potential of the COCs bears a relation to morphological appearance, relative expression of a panel of genes associated with; (a) cumulus-oocyte interaction (Cx43, Cx37, GDF9 and BMP15), (b) fertilization (ZP2 and ZP3), (c) embryonic development (HSF1, ZAR1 and bFGF) and (d) apoptosis and survival (BAX, BID and BCL-XL, MCL-1, respectively) was studied at two stages: germinal vesicle (GV) stage and after in vitro maturation. The competence was further corroborated by evaluating the embryonic progression of the presumed zygotes obtained from fertilization of the graded COCs. The gene expression profile and development rate in pooled A and B grade (Group 1) COCs and pooled C and D grade (Group 2) COCs were determined and compared according to the original grades. The results of the study demonstrated that the morphologically characterized Group 2 COCs showed significantly (P<0.05) lower expression for most of the genes related to cumulus-oocyte interplay, fertilization and embryonic development, both at GV stage as well as after maturation. Group 1 COCs also showed greater expression of anti-apoptotic genes (BCL-XL and MCL1) both at GV stage and after maturation, while pro-apoptotic genes (BAX and BID) showed significantly (P<0.05) elevated expression in poor quality COCs at both the stages. The cleavage rate in Group 1 COCs was significantly higher than that of Group 2 (74.46±7.06 v. 31.57±5.32%). The development of the presumed zygotes in Group 2 oocytes proceeded up to 8- to 16-cell stages only, while in Group 1 it progressed up to morulae (35.38±7.11%) and blastocyst stages (9.70±3.15%), indicating their better developmental potential.

This study aimed to explore the association of maternal depression with nutrient intake, growth, and development of preterm infants. A cohort study of 201 infants was conducted in Beijing. Based on the gestational age of an infant and status of the mother, the infants were divided into four groups: non-depression-fullterm (64), non-depression-preterm (70), depression-fullterm (36), and depression-preterm (31). Data on sociodemographic characteristics, nutritional intake, growth, and developmental status of children at 8 months (corrected ages) were collected using a quantitative questionnaire, a 24-Hour Dietary Recall, anthropometric measurements, and the Bayley-III scale. A multivariate analysis was used to evaluate the effects of maternal depression and preterm birth on infant growth and development. The energy, protein, and carbohydrate intake in the depression group was lower than the recommended amounts. The depression preterm groups indicated the lowest Z-scores for length and weight and the lowest Bayley-III scores. Preterm infants of depressed mothers are at high risks of poor growth and development delay.

The development of preventive interventions targeting adolescent problem behaviors requires a thorough understanding of risk and protective factors for such behaviors. However, few studies examine whether different cultural and ethnic groups share these factors. This study is an attempt to fill a gap in research by examining similarities and differences in risk factors across racial and ethnic groups. The social development model has shown promise in organizing predictors of problem behaviors. This article investigates whether a version of that model can be generalized to youth in different racial and ethnic groups (N = 2,055, age range from 11 to 15), including African American (n = 478), Asian Pacific Islander (API) American (n = 491), multiracial (n = 442), and European American (n = 644) youth. The results demonstrate that common risk factors can be applied to adolescents, regardless of their race and ethnicity. The findings also demonstrate that there are racial and ethnic differences in the magnitudes of relationships among factors that affect problem behaviors. Further study is warranted to develop a better understanding of these differential magnitudes. PMID:21625351
