There is a widespread assumption that study abroad develops skills that are marketable in an increasingly global market. Students at many institutions, including Old Dominion University (ODU), have undertaken study abroad mostly after their sophomore year, well after they have chosen a major. The profile of U.S. students studying abroad compiled…

It is important to understand and identify factors that affect students' academic performance before entry into a nursing program and as they progress through the program. The authors discuss a study, and its outcomes, that assessed accelerated second-degree nursing students' prenursing and core nursing grades that served to predict their success at completing the nursing program and passing NCLEX-RN on first attempt. Strategies were identified to help at-risk students to be successful in the program and with first-time passage of NCLEX-RN.

This study aims to compare and evaluate the learning ability and performance differences between two groups of students undergoing project-based learning (PjBL), with one group having prior PjBL experience, while the other group is being freshly exposed to PjBL. More specifically, it examines if there are significant differences in knowledge score, problem-solving ability, and eventual project-deliverable outcomes between the two sets of students. Performances were compared via qualitative and quantitative analyses. Key findings have indicated a significant increase in fundamental formative knowledge; enhanced problem-solving abilities; and production of better performing artefacts with regard to the set of design skills between experienced and first-time PjBL groups. This study also highlighted that experienced PjBL students have less conflicts within their groups, and are more receptive to PjBL compared to first-time PjBL students. Results from this study provide a starting point for educators to seek new learning/facilitating strategies that are relevant based on the experience and learning styles of students.

The Department of Geological Sciences at California State University, Fullerton (CSUF) is one of the largest geology programs in the state. Approximately 4,000 students at CSUF take general education geology classes; this provides a large pool from which to recruit undergraduate students for either the Geology B.S. or Earth Sciences B.A. offered by the department. The department has seen a dramatic increase in majors over the last decade, from a low of 28 majors in 2002 to more than 110 in 2012. This increase does not appear to be driven by growth in the oil industry; in a recent survey of CSUF geoscience (BS or BA) students, 15% of respondents indicated an interest in a career in petroleum. The department has engaged in aggressive recruitment and outreach efforts over the last decade, with activities ranging from earthquake preparedness rallies in conjunction with the annual California ShakeOut, to an emerging high school and community college intern program at the department's paleontology curation facility. Despite these efforts, the majority of CSUF geoscience students declared the geology major after taking an introductory physical geology course either at CSUF or a local community college. Over the last ten years, approximately 50% of the geoscience majors at CSUF transferred from a community college. Among the geoscience students who began their career at CSUF, only one third had declared a geoscience major in their freshman year. Over two thirds of geoscience majors at CSUF declared their major after completing more than 60 units. The strong tendency for students to declare a geoscience major late in their career poses significant challenges to students' ability to graduate in a timely manner. To mitigate this problem, the department has an aggressive advising program, wherein students attend mandatory advising with a faculty member every semester. The department is also working closely with community college partners to improve the preparation of transfer

A diagnostic test administered at the start of a class should test basic concepts which are recognized as course prerequisites. The questions should not be over-packaged: e.g. students should be required to create models, rather than this being done for them each time. Students should be allowed great latitude in their answers, so we can discover what they are thinking. When administered at the end of a class the goals should be similar: testing concepts taught in the class itself and the retention of necessary concepts from previous classes. Great care has to be taken to avoid teaching to the test. In assessing an entire program, for example an undergraduate majors degree in physics, then one looks for very general skills and knowledge not specific to any one course. The purpose of an undergraduate degree in physics (or indeed any science) is to equip the students with a set of problem-solving skills and basic knowledge which can be applied in a large variety of workplace settings and to allow that student to contribute to civic society as a science-literate person. The creator of any diagnostic test should always have these big goals in mind. We have developed a set of questions which we think fulfill these criteria, yet are not specific to any particular level of science education. They have been administered to students in secondary schools across Canada, incoming first-year science students and final-year physics students at the University of British Columbia. The results will be presented.

There are a number of anecdotal reports on demographic characteristics and academic success of accelerated-nursing students; yet few empirical studies have examined accelerated-nursing students NCLEX-RN success. Applying Knowles' adult learning theory as a guiding framework, the purpose of this qualitative study was to explore, from the accelerated-nursing students' perspective, the factors reported as contributing to their success on the NCLEX-RN. The research questions aimed to elicit participants' descriptions of their experiences and factors contributing to their success via individual interviews. The most significant finding the participants identified as the factor that contributed to their success was the practicing of NCLEX-RN questions. The findings of this study have several implications for educational policy and practice for universities and schools of nursing as the information gained from this study applies to recruitment and retention as well as curriculum and educational strategies in an accelerated-nursing program.

The academic and personality correlates of medical career indecision were investigated in two separate studies. In the first, the effect of career indecision on academic performance was examined in a group of ninety-eight (eighty male, eighteen female) medical students entering Texas Tech University School of Medicine over a 2-year period. These medical students voluntarily completed the Medical Specialty Preference Inventory (MSPI) as part of a routine preadmission test battery. Subjects were assigned to one of three conditions-decided, high-interest undecided and low-interest undecided--based on results from the MSPI. As predicted, 'low-interest undecided' students achieved significantly lower initial medical school grades relative to 'decided' students, whereas 'high-interest undecided' students did not differ from the 'decided' students. The second study investigated the influence of career indecision upon personality. Subjects for this study were eighty-eight (sixty-six male, twenty-two female) medical students entering Texas Tech University School of Medicine over a 1-year period. These students voluntarily completed the MSPI and several personality measures as part of a pre-admission test battery. The results only partially supported the stated hypotheses. Although 'low-interest undecided' students demonstrated less personal integration compared with 'decided' students, they were no more anxious.

Background In this observational study, we aimed to see whether transition in Saudi students entering university life could be a breeding stage for cardiometabolic risk factor emergence and clustering. Methods A total of 1878 apparently healthy Saudi students of the Preparatory Year, King Saud University, Riyadh, KSA (1112 men and 766 women) spanning 2 academic years were included. They were divided into 2 groups based on the validated perceived stress test (PST). Anthropometrics were obtained and fasting blood samples were collected for measurement of fasting blood glucose and a lipid profile. Results PST score (>27) considered indicative of stress was noted in 44.4% of students. The prevalence of this score was higher in women than in men (49.7% versus 40.7%). The prevalence of obesity, hypertension and dyslipidemia was significantly higher in men than women (p < 0.01), and this was even more apparent among stressed men, who had a significantly higher prevalence of all the above cardiometabolic factors than the non-stressed ones (p < 0.01). Conclusion Perceived stress is alarmingly high among Saudi students entering universities. This study sheds light on the social responsibility of universities in promoting a healthy lifestyle, particularly in this age group, when exposure to different kinds of stressors may result in body weight and metabolic changes.

The aim of this study was to explore the motivations of student nurses enrolled in nursing courses across a variety of Pacific Island countries. The image of nursing, the desire to help others, family and friends in the profession, personal experience, security, travel opportunities and flexibility have all been identified as motivators for people to enter nursing. To date, what motivates students in Pacific Island countries to enrol in a nursing course has not been investigated. An exploratory qualitative approach using focus group interviews with 152 nursing students was undertaken. Data were analysed using thematic content analysis, revealing four themes: (i) helping others; (ii) 'making a difference for my people'; (iii) following in the footsteps of others; and (iv) financial and professional gain. In a time of health and nursing workforce shortages, developing a deeper understanding of what drives people can be used to improve recruitment strategies in the future.

For languages other than English there is a lack of empirical evidence about the cognitive profile of students entering higher education with a diagnosis of dyslexia. To obtain such evidence, we compared a group of 100 Dutch-speaking students diagnosed with dyslexia with a control group of 100 students without learning disabilities. Our study showed selective deficits in reading and writing (effect sizes for accuracy between d = 1 and d = 2), arithmetic (d≈1), and phonological processing (d>0.7). Except for spelling, these deficits were larger for speed related measures than for accuracy related measures. Students with dyslexia also performed slightly inferior on the KAIT tests of crystallized intelligence, due to the retrieval of verbal information from long-term memory. No significant differences were observed in the KAIT tests of fluid intelligence. The profile we obtained agrees with a recent meta-analysis of English findings suggesting that it generalizes to all alphabetic languages. Implications for special arrangements for students with dyslexia in higher education are outlined. PMID:22719864

This is a qualitative study, based on Heidegger's existential phenomenology, with the purpose of revealing the meaning of death/dying for freshmen students of the nursing program. The study was developed in a public university in the northwest of Paraná, Brazil between August and October 2010, and 33 entering students from a Nursing program were interviewed. The following existential themes emerged from the phenomenological analysis: "Understanding death as a difficult process to be understood"; "Understanding death as a natural process"; and "Perceiving death as a passage to another life". The present study allowed to understand that knowledge and death are entangled in the temporality and the historicity of every being, which requires a scientific, ethical and philosophical understanding of the death/dying phenomenon so that the scholar may prepare for the humanized care of the patient and his/her family.

This study aimed to ascertain whether medical students would enter a closed area where there was a raging epidemic of an infectious disease with a high fatality rate, and includes reasons for the students entering or refusing to enter. Participants included 50 second-year medical students. They were assigned to read a novel entitled 28, written by Youjeong Jeong, and discuss it in groups. Using their book reports, their decisions of whether or not to enter Hwayang, the city from the novel, and the reasons for their decisions were analyzed; we furthermore investigated the factors affecting their decisions. Among the 50 respondents, 18 students (36%) answered that they would enter, and the remaining 32 students (64%) answered that they would not enter the zone. The reasons given for entering were responsibility (44%), sense of ethics (33%), social duty (17%), and sense of guilt (6%). The reasons the students provided for not entering were inefficiency (44%), worry regarding family (28%), needlessness of sacrifice (19%), and safety not ensured (9%). Students who had four or fewer family members were more likely to enter Hwayang than were students who had five or more family members (odds ratio, 1.85). Students who had completed over 100 hours of volunteer work were more likely to enter Hwayang than were students who had volunteered less than 100 hours (odds ratio, 2.04). Owing to their "responsibility" as a doctor, 36% of medical students answered that they would enter an exclusion zone in an infected district with a high fatality rate. However, 64% answered they would not enter because of "inefficiency." For the medical students it is still a question 'To enter or not to enter?'

African American, Hispanic/Latina, and American Indian/Alaska Native persons are markedly underrepresented racial and ethnic groups (UREG) in the dental hygiene profession. The purpose of this study was to survey UREG dental hygiene students to determine their perceptions of the barriers and facilitators that influenced their decision to enter the dental hygiene profession. Participants were eighty-four UREG students attending entry-level dental hygiene programs across the state of California. We conducted face-to-face interviews using a survey guide that consisted of forty-two mostly closed-ended questions. Most (57 percent) participants reported that they had either perceived or experienced barriers: primarily costs associated with the program and the lack of role models in their race/ethnicity. Almost all participants reported that there had been a person, mainly a dental professional, who influenced them to become a dental hygienist; 62 percent of these individuals were reported to be from a similar UREG group as the participant. Funding (57 percent) and emotional support from family and friends (87 percent) were the predominant facilitators employed by the participants to overcome barriers. Based on these results, we recommend three strategies to recruit more UREG students into the dental hygiene profession: more extensive outreach programs, enhanced mentoring by UREG dental professionals, and a modified admission process.

Dismantling is a complex psychic phenomenon, which is not easy to define, and little interest has been shown in the subject. The authors of this paper want to demonstrate that dismantling is the main defense mechanism in autism, bringing about de-consensus of senses. The effects perceived in a child with autistic disorder are passivity and lack of thought. The authors’ purpose here is to define the dismantled state and reveal its underlying process. This paper will therefore describe for the first time in literature, the dismantling phenomenon and will submit a metapsychological approach of this defense mechanism. PMID:25999871

Introduction Neurocysticercosis is a common cause of seizures in low resource countries. There is a paucity of data regarding the extent of this infection in Namibia. There are multiple causes of First-time seizure including electrolyte abnormalities, infections, trauma, drugs, alcohol and many times no apparent cause can be found. We sought to describe the burden of Neurocysticercosis among individuals with a first-time seizure in Namibia. Methods We recruited 221 patients with a First-time seizure who presented to the Intermediate Hospital Oshakati between August 2012 and March 2014. Patients with seizures due to identifiable causes like trauma, electrolytes, intoxications and meningitis were excluded. Brain CT scans were done, blood serological testing of Neurocysticercosis antibodies, Physical examination and demographic variables were collected. Data was entered into Epidata version 3.1 and transferred to stata version for analysis. Results Ninety-six (96) of the participants had evidence of Neurocysticercosis on Brain CT scan representing a prevalence of 51.41%. Consumption of pork and rearing of pigs in the homestead were significant factors associated with Neurocysticercosis in our study population with odds of 3.48(1.45-8.33) and 2.07(1.11-3.86) respectively. Serological testing for Cyticercosis IgG had a sensitivity of 65.93% and Specificity of 96.51%. The positive and negative predictive values were 95.2% and 72.81% respectively. Conclusion Neurocysticercosis is a common cause of Index seizures in Northern Namibia, living in a rural area, rearing pigs in homesteads, eating pork and poor sanitary practices are the major risk factors for this illness.

In this prospective study we wanted to determine whether perceived stress over time among students in the Preparatory Year of King Saud University (KSU) predisposes them to cardiometabolic abnormalities. A total of 110 apparently healthy Saudi students (35 men and 75 women enrolled during the 2010−2011 academic year) were included. Perceived stress was determined at baseline and 1 year later. Anthropometrics were obtained and morning fasting serum glucose, lipid profile and cortisol were measured at both times. Perceived stress was noted among 48.2% of subjects at baseline and was not significantly different after follow-up, with 45.4% scoring high. In men, the prevalence of perceived stress was 48.6% at baseline (13 out of 35) and 37.1% at follow-up (13 out of 35), while in women it was 48% at baseline and 49.3% at follow-up. Interestingly, significant improvements in the blood pressure and lipid profiles, with the exception of HDL-cholesterol, were observed in both men and women, while fasting glucose also improved in women. Serum cortisol was inversely associated to fasting glucose, and total- and LDL-cholesterol (p-values 0.007, 0.04 and 0.04, respectively). These data are opposite to findings in students entering Western universities, in whom increasing stress and a deteriorating cardiometabolic profile have been repeatedly noted. Perceived stress and morning cortisol levels among students of the Preparatory Year in KSU remained constant for both genders over time, yet an improved cardiometabolic profile was observed, suggesting good adaptation among our pre-college students in their first year of university life.

In the studies reported, evidence has been presented that U.S. students traveling to Mexico represent a model for the study of travelers' diarrhea. The incidence of illness acquisition approximates that published in other studies of travelers. Natural immunity was shown to develop as students remained in Mexico presumably through repeated exposure to prevalent agents, particularly ETEC. ETEC, shigella strains and no detectable agent represented the largest groups when etiologic assessment was made. Food probably served as the important source of diarrhea particularly that due to ETEC and shigella strains. The level of bacteria isolated from food suggested that organism replication occurred due to improper temperature storage rather than to heavy initial contamination. The location of food consumption was related to degree of risk: self preparation was the safest, eating in Mexican homes the least safe and consumption of food in public restaurants was intermediate in risk. Water probably played a role in the transmission of viral infection. The risk of water contamination appeared to be highest during the rainy seasons. Finally, the antimicrobial agents TMP/SMX and TMP alone were shown to effectively prevent and treat this form of travelers' diarrhea. PMID:3837965

The objectives of this study were to assess the level of knowledge on HPV and HPV vaccination, and to determine vaccination attitude among Ege university students in Izmir, Turkey. A cross-sectional survey was conducted in first-year English preparatory class. Systematic cluster sampling was applied and 717 (72.6%) of students registered to the 54 classes in 17 different faculties/schools were contacted. Data were collected between April 30 and May 18, 2010, through a self-reported questionnaire including 40 questions. A knowledge score was calculated by summing up the number of correct answers given to the 12 knowledge questions. Analyses were done using t-test, chi-square test, univariate and multivariate logistic regression. The mean age of participants was 19.7±1.5 and 445 (62.1%) were female. Overall, 132 (18.9%) had experienced sexual intercourse, but only 7 of them were female. Among participants, 24.1% had heard of HPV and 25.1% about HPV vaccine. The knowledge item with the highest correct answer rate (32.3%) was that HPV caused cervical cancer. The mean total knowledge score was remarkably poor (1.8±2.6 over 12 items), with 59.6% of respondents having zero as their score. There was no difference in mean knowledge scores between males and females. Higher income, history of sexual intercourse and higher knowledge score were significant factors increasing HPV and vaccine awareness for the whole group, adjusted for gender. Genital cancer history in the family significantly increased awareness, but only among girls. Only three students (0.4%) had already been vaccinated, all being female. Among females, 11.6% intended to be vaccinated vs. 10.1% for males, without any significant difference. Visiting a gynaecologist/urologist in the last three years, a history of genital cancer in the family, vaccine awareness, a higher total knowledge score, and being from the East of Turkey were significant predictors of a positive vaccination attitude.

The transition from medical student to intern is a challenging process characterized by a steep learning curve. Focused courses targeting skills necessary for success as a resident have increased self-perceived preparedness, confidence, and medical knowledge. Our aim was to create a brief educational intervention for 4th-year medical students entering pediatric, family practice, and medicine/pediatric residencies to target skills necessary for an internship. The curriculum used a combination of didactic presentations, small group discussions, role-playing, facilitated debriefing, and simulation-based education. Participants completed an objective structured clinical exam requiring synthesis and application of multiple boot camp elements before and after the elective. Participants completed anonymous surveys assessing self-perceived preparedness for an internship, overall and in regards to specific skills, before the elective and after the course. Participants were asked to provide feedback about the course. Using checklists to assess performance, students showed an improvement in performing infant lumbar punctures (47.2% vs 77.0%; p < 0.01, 95% CI for the difference 0.2, 0.4%) and providing signout (2.5 vs. 3.9 (5-point scale) p < 0.01, 95% CI for the difference 0.6, 2.3). They did not show an improvement in communication with a parent. Participants demonstrated an increase in self-reported preparedness for all targeted skills, except for obtaining consults and interprofessional communication. There was no increase in reported overall preparedness. All participants agreed with the statements, “The facilitators presented the material in an effective manner,” “I took away ideas I plan to implement in internship,” and “I think all students should participate in a similar experience.” When asked to assess the usefulness of individual modules, all except order writing received a mean Likert score > 4.

The benefits, equipment used, commercially available sources, and the indications and techniques for administration of enteral nutrients are reviewed. In many malabsorption states, enteral feeding is preferable and parenteral nutrients are seldom indicated. Transitional enteral nutrient support usually is indicated after parenteral nutrient therapy. Enteral tube-feeding formulas should be matched to the patient's needs; formulas using blenderized natural foods or intact isolated nutrients are appropriate for patients with intact gastrointestinal tracts. Patients should be monitored for glucosuria and hyperglycemia, bloating, nausea, dehydration, and renal, hepatic and hematologic status. Formula dilution, and a reduced flow rate or use of continuous-drip feeding, will reduce the incidence of osmotic diarrhea. The effectiveness, low cost and low potential for serious complications make enteral feeding preferable to parenteral nutrient therapy for many patients.

Radiation enteritis continues to be a major health concern in recipients of radiation therapy. The incidence of radiation enteritis is expected to continue to rise during the coming years paralleling the unprecedented use of radiotherapy in pelvic cancers. Radiation enteritis can present as either an acute or chronic syndrome. The acute form presents within hours to days of radiation exposure and typically resolves within few weeks. The chronic form may present as early as 2 months or as long as 30 years after exposure. Risk factors can be divided into patient and treatment-related factors. Chronic radiation enteritis is characterized by progressive obliterative endarteritis with exaggerated submucosal fibrosis and can manifest by stricturing, formation of fistulae, local abscesses, perforation, and bleeding. In the right clinical context, diagnosis can be confirmed by cross-sectional imaging, flexible or video capsule endoscopy. Present treatment strategies are directed primarily towards symptom relief and management of emerging complications. Recently, however, there has been a shift towards rational drug design based on improved understanding of the molecular basis of disease in an effort to limit the fibrotic process and prevent organ damage.

Objectives: Obesity and increased blood pressure are identified as risk factors for cardiac and pulmonary disorders. On the other hand, iron deficiency (another preventable disease) is common in adolescence and considered as associated with health impairment. The present study evaluates body mass index (BMI) and its association with blood pressure and hematological indices in freshman students entering the University of Isfahan in 2009. Methods: All the 1675 students who entered the University of Isfahan in September 2009 were examined. Height, weight, BMI, blood pressure, hemoglobin (Hb) and red blood cell (RBC) indices of these students were measured. The prevalence of high blood pressure, its association with BMI and the relation between BMI and anemia, iron deficiency and educational achievement were assessed. Results: All participants, including 514 males and 1161 females, went under clinical observations. The average age was 20.7 ± 3.8. year Among the students, 18.2% of males and 20% of females were underweight. High systolic blood pressure was more common in the students with BMI > 25 kg/m2 (p < 0.001). Anemia was seen in 8.7% of females. In males, however, a relation between anemia frequency and BMI < 18.5 kg/m2 was more distinct (p = 0.002). There was no association between anemia and students’ average test scores. Conclusions: High incidence of abnormal BMI in the study population, and its association with systolic blood pressure indicate the importance of nutritional guidelines and counseling programs for freshman students. On the other hand, high incidence of anemia in this population ascertains the necessity of anemia screening programs before academic studies. PMID:22174970

GeoFORCE Texas is an outreach program of the Jackson School of Geosciences, University of Texas at Austin. Established in 2005 with the goal of increasing the number and diversity of students studying geosciences and engineering and entering the high-tech workforce, GeoFORCE has been highly successful. Key elements to that success will be presented here. GeoFORCE targets bright students in rural and inner-city schools where they are generally not academically challenged. Every summer throughout high school we take them on geologic field trips all over the country. In 2014, GeoFORCE led 15 field academies for about 600 students. The program is rigorous and academic. We emphasize college-level thinking skills. Because it is a 4-year program, they have a pretty good grounding in physical geology by the time they graduate. More importantly, they develop confidence in their ability to handle college, and a strong motivation to earn a college degree. GeoFORCE students are mostly minority (85%) and more than half will be the first in their family to graduate from college. GeoFORCE students exceed national averages in rates of going to college (97%), majoring in STEM fields (66%), majoring in geosciences (15%) and engineering (13%), and graduating from college (~85%). GeoFORCE is a public/private partnership and a workforce-focused program. The Jackson School funds staff and operating expenses (37%). Money for student programs comes from private industry (44%), state and federal grants (14%), and foundations and individual donors (5%). Our corporate partners are in the energy sector. In addition to funding, corporate sponsors attend the summer field programs, mentor GeoFORCE students, and provide opportunities for the students to visit the companies. As our students move toward college graduation, our industry and government partners have begun to hire them as interns. GeoFORCE graduates are now entering the workforce. Our first two cohorts are 4 and 5 years past high

Although poor health-related behaviors that impact development of chronic diseases begin much earlier than when actual disease is evident, few studies have examined health behaviors in college students, who may be at an important transitional period where early intervention could prevent development of chronic diseases. The purpose of this study was to examine health-related factors in female college students (N = 61) by race/ethnicity and weight status. We found significant differences in health profiles between non-Hispanic White (White) and African American students, including greater physical fitness and healthier diets among White students. Overweight/obese students had worse health profiles than healthy BMI students. Furthermore, weight status was significantly associated with cardiovascular fitness. This supports a focus on PA promotion for interventions in the period of emerging adulthood, alongside the other healthy behaviors, to elicit improvements in weight status and potential reduction of chronic disease risks.

Enteric fever is an important public-health problem in India. The clinical presentation of typhoid fever is very variable, ranging from fever with little other morbidities to marked toxemia and associated multisystem complications. Fever is present in majority of patients (>90 %) irrespective of their age group. Mortality is higher in younger children. Blood culture remains gold standard for diagnosis. Widal test has low sensitivity and specificity but may be used in second week to support the diagnosis. Emerging resistance to several antibiotics should be kept in mind when selecting antibiotics or revising the treatment. The key preventive strategies are safe water, safe food, personal hygiene, and appropriate sanitation. Vaccination is an additional effective tool for prevention.

Which perceptual and cognitive prerequisites must be met in order to be able to comprehend a film is still unresolved and a controversial issue. In order to gain some insights into this issue, our field experiment investigates how first-time adult viewers extract and integrate meaningful information across film cuts. Three major types of commonalities between adjacent shots were differentiated, which may help first-time viewers with bridging the shots: pictorial, causal, and conceptual. Twenty first-time, 20 low-experienced and 20 high-experienced viewers from Turkey were shown a set of short film clips containing these three kinds of commonalities. Film clips conformed also to the principles of continuity editing. Analyses of viewers' spontaneous interpretations show that first-time viewers indeed are able to notice basic pictorial (object identity), causal (chains of activity), as well as conceptual (links between gaze direction and object attention) commonalities between shots due to their close relationship with everyday perception and cognition. However, first-time viewers' comprehension of the commonalities is to a large degree fragile, indicating the lack of a basic notion of what constitutes a film.

The purpose of the current study was to examine whether the differences found between first time and repeat rural DUI offenders were the same as those found previously in urban samples. A total of 118 rural DUI offenders were interviewed, approximately half (51.7%) of which were repeat offenders. Although demographic and mental health characteristics were similar across the two groups, repeat offenders reported more extensive substance use and criminal histories. Results suggest that the pattern of differences between rural first time and repeat DUI offenders may be different from the pattern found in prior urban-based studies. Treatment implications are discussed. PMID:26225118

A major indicator of baccalaureate nursing program effectiveness is the pass rate on the National Council Licensure Examinations, Registered Nurse (NCLEX-RN) among first-time candidates. This article highlights the scope, instructional methods, and outcomes of the remediation program at Georgetown University School of Nursing & Health Studies (GU-NHS). With implementation of the multifaceted program, the NCLEX-RN pass rate for first-time takers at GU-NHS has been consistently above the national mean among all first-time candidates. Although it is impossible to determine which strategy made the greatest contribution to the success of the program, the cumulative effect is impressive and indicates the students are prepared for the challenge of the examination and contemporary nursing practice.

Patellofemoral instability is a complex problem, which can be difficult to manage. The purpose of this study was to describe the demographics of patients with a first-time patellofemoral dislocation, and identify risk factors for recurrent instability. This was a single institution, institutional review board-approved, retrospective review of >2,000 patients with a patellar dislocation between 1998 and 2010. Inclusion criteria are as follows: (1) no prior history of patellofemoral subluxation or dislocation of the affected knee; (2) X-rays within 4 weeks of the initial instability episode; and (3) a dislocated patella requiring reduction, or history/findings suggestive of acute patellar dislocation (effusion/hemarthrosis, tenderness along the medial parapatellar structures, and apprehension with lateral patellar translation). Clinical records and radiographs were reviewed. The Caton-Deschamps and Insall-Salvati indices were used to evaluate patella alta. Trochlear dysplasia was assessed using the Dejour classification system. Skeletal maturity was graded based on the distal femoral and proximal tibial physes, using one of the following categories: open, closing, or closed. Three hundred twenty-six knees (312 patients) met the aforementioned criteria. There were 145 females (46.5%) and 167 males (53.5%), with an average age of 19.6 years (range, 9-62 years). Thirty-five patients (10.7%) were treated with surgery after the initial dislocation. All others were initially managed nonoperatively. Of the 291 patients managed nonoperatively, 89 (30.6%) had recurrent instability, 44 (49.4%) of which eventually required surgery. Several risk factors for recurrent instability were identified, including younger age (p < 0.01), immature physes (p < 0.01), sports-related injuries (p < 0.01), patella alta (p = 0.02), and trochlear dysplasia (p < 0.01). Sixty-nine percent of patients with a first-time patellofemoral dislocation will stabilize with conservative

NASA's Chandra X-ray Observatory detected sound waves, for the first time, from a super-massive black hole. The "note" is the deepest ever detected from an object in the universe. The tremendous amounts of energy carried by these sound waves may solve a longstanding problem in astrophysics. The black hole resides in the Perseus cluster, located 250 million light years from Earth. In 2002, astronomers obtained a deep Chandra observation that shows ripples in the gas filling the cluster. These ripples are evidence for sound waves that have traveled hundreds of thousands of light years away from the cluster's central black hole. perseus animation Illustration of Ripples in Perseus "We have observed the prodigious amounts of light and heat created by black holes, now we have detected the sound," said Andrew Fabian of the Institute of Astronomy (IoA) in Cambridge, England, and leader of the study. In musical terms, the pitch of the sound generated by the black hole translates into the note of B flat. But, a human would have no chance of hearing this cosmic performance, because the note is 57 octaves lower than middle-C (by comparison a typical piano contains only about seven octaves). At a frequency over a million, billion times deeper than the limits of human hearing, this is the deepest note ever detected from an object in the universe. "The Perseus sound waves are much more than just an interesting form of black hole acoustics," said Steve Allen, also of the IoA and a co-investigator in the research. "These sound waves may be the key in figuring out how galaxy clusters, the largest structures in the universe, grow," Allen said. For years astronomers have tried to understand why there is so much hot gas in galaxy clusters and so little cool gas. Hot gas glowing with X-rays should cool, and the dense central gas should cool the fastest. The pressure in this cool central gas should then fall, causing gas further out to sink in towards the galaxy, forming trillions of

Common to all pediatric patients receiving enteral nutrition is the inability to consume calories orally. This is often secondary to issues of inadequate weight gain, inadequate growth, prolonged feeding times, weight loss, a decrease in weight/age or weight/height ratios, or a persistent triceps skinfold thickness <5% for age. Enteral nutrition requires enteral access. In the neonatal period the nasoenteric route is usually used. In pediatric patients requiring long-term enteral access, surgically, endoscopically, or radiologically placed percutaneous feeding tubes are common. Jejunal feeding tubes are used in pediatric patients with gastric feeding intolerance or persistent gastroesophageal reflux. Low-profile enteral access devices are preferred by most pediatric patients because of their cosmetic appearance. For most children, a standard pediatric polypeptide enteral formula is well tolerated. There are specialized pediatric enteral formulas available for patients with decreased intestinal length, altered intestinal absorptive capacity, or altered pancreatic function. Weaning patients from tube feeding to oral nutrition is the ultimate nutrition goal. A multidisciplinary approach to patients with short bowel syndrome will maximize the use of enteral nutrition while preserving parenteral nutrition for patients with true enteral nutrition therapy failure.

Objective. To describe the education, training, and academic experiences of newly hired faculty members at US colleges and schools of pharmacy during the 2012-2013 academic year. Methods. A survey regarding education, training, and academic experiences was conducted of all first-time faculty members at US colleges and schools of pharmacy hired during the 2012-2013 academic year. Results. Pharmacy practice faculty members accounted for the majority (68.2%) of new hires. Ambulatory care was the most common pharmacy specialty position (29.8%). Most new faculty members had a doctor of pharmacy (PharmD) as their terminal degree (74.8%), and 88.3% of pharmacy practice faculty members completed a residency. Of new faculty members who responded to the survey, 102 (67.5%) had at least 3 prior academic teaching, precepting, or research experiences. Conclusion. New faculty members were hired most frequently for clinical faculty positions at the assistant professor level and most frequently in the specialty of ambulatory care. Prior academic experience included precepting pharmacy students, facilitating small discussions, and guest lecturing.

The gastrointestinal form of food allergy is very common in children. The most frequently observed types are allergic proctitis and proctocolitis. In most cases the symptoms subside within the first 2 months of life. The babies seem healthy, and the only abnormality is a small amount of blood in stool. Symptoms can also include small intestine inflammation and colitis. Patients may present with irritability, abdominal pain, flatulence, colic, postprandial vomiting, chronic diarrhoea, and hindered physical development. The diagnosis of allergic enteritis is based on the clinical examination and the results of additional tests including an endoscopy of the lower digestive tract with histopathological assessment. Cow’s milk proteins are the most common nutrition proteins responsible for the development of the symptoms of allergic enteritis. The most essential method of treating allergic enteritis is the elimination diet. The symptoms should subside within 1–2 weeks from the beginning of the diet. PMID:28337229

In this study, the intestinal endocrine cells were investigated in 13 surgical specimens affected by radiation enteritis. Endocrine cells were studied by means of Grimelius' silver staining and immunostaining for chromogranin, a general marker of endocrine cells. Positively stained cells were quantified by counting their number per unit length of muscularis mucosa. Results in radiation enteritis were compared with matched control specimens by using Student's t test. Chromogranin immunostaining showed a statistically significant increase of endocrine cells in radiation enteritis specimens compared with controls both in small and large intestine (ileum, 67.5 +/- 23.5 cells per unit length of muscularis mucosa in radiation enteritis versus 17.0 +/- 6.1 in controls; colon, 40.9 +/- 13.7 cells per unit length of muscularis mucosa in radiation enteritis versus 9.5 +/- 4.1 in controls--p less than 0.005 in both instances). Increase of endocrine cells was demonstrated also by Grimelius' staining; however, without reaching statistical significance. It is not clear whether or not the increase of endocrine cells in radiation enteritis reported in this study is caused by a hyperplastic response or by a sparing phenomenon. We should consider that increased endocrine cells, when abnormally secreting their products, may be involved in some of the clinical features of radiation enteropathy. In addition, as intestinal endocrine cells produce trophic substances to the intestine, their increase could be responsible for the raised risk of developing carcinoma of the intestine in long standing radiation enteritis.

New enteral connectors are now available based on the development of standards using the International Organization of Standardization process to prevent misconnections between systems that should not connect. Enteral devices with the new patient access connectors, called ENFit, are being now introduced for the purpose of improving patient safety. Transitioning to these new connectors poses benefits and challenges for facilities or agencies implementing these new devices. Information from appropriate resources should be sought by clinicians who need to partner with their suppliers and clinical organizations to see how best to meet these challenges.

The recent launch of a number of fibre enriched polymeric diet in the United States and Europe has stimulated considerable interest in the topic of fibre and enteral nutrition, and several commercial concerns appear to be under considerable pressures from their consumers to produce similar products. As a means of identifying areas of potential application of fibre to enteral nutrition some of the recent knowledge gained about the physical properties of dietary fibre and the processes involved in the intestinal assimilation of fibre has been reviewed. Two areas of interest are identifiable. The first relates to the bulking properties of fibre and the application of this to the regulation of bowel function in enterally fed patients. It is clear from the clinical studies that have been reviewed that there remains a paucity of controlled data, and a great deal more research is needed before widespread use of fibre supplemented diets can be supported. Perhaps of greater interest academically is the potentially beneficial effects that appear to be exerted by the VFA's, liberated as a consequence of colonic bacterial fermentation of fibre, on morphology and function of ileal and colonic mucosa. Although there are a number of potential applications of fibre supplemented enteral diets in this area, more research is required before any firm recommendations can be made about recommending their use. The one exception concerns patients with the nutritionally inadequate short bowel syndrome. There does seem to be sufficient experimental evidence to suggest that clinical studies should be commenced using a pectin supplemented predigested 'elemental' diet in these patients. Overall therefore, one is forced to conclude that the increasing interest and use of fibre supplemented enteral diets is being driven more by market than scientific forces. Nevertheless, the promotion of these diets has already provided a powerful stimulus to the scientific community, and it remains entirely

When oral intake is unsatisfactory or contraindicated, maintenance of nutrition by tube feeding is an alternative to the parenteral route. A large volume of research data supports the decision to use the enteral route whenever possible. Entry of food into the alimentary tract is a stimulus to structural and functional maintenance of that tract. Enteral nutrition can be given via indwelling nasoesophageal, pharyngostomy, esophagostomy, percutaneous or surgical gastrostomy, or enterostomy tube. Use of an appropriate catheter, familiarity with the technique used, and careful patient selection and monitoring are important factors in successful tube feeding. Blenderized pet food diets should be fed whenever possible; commercially available liquid diets provide an alternative when tube caliber or patient factors preclude the use of blenderized foods.

Fatherhood, as a developmental process, is both a human experience and a text that needs to be read. For developing nations like the Philippines, little is known about the process undergone by first-time fathers on their transition to fatherhood, and how nurses can play a significant role in assisting them. This grounded theory study purported to conceptualize the multifaceted process of transition from the lens of Filipino first-time fathers' lived experiences. A total of 20 first-time fathers from Metro Manila, Philippines, were purposively selected to take part in an individual, semistructured, and in-depth interview. The Glaserian (classical) method of analysis was specifically used, and field texts were inductively analyzed using a repertory grid. Member checking and correspondence were done to validate the findings of the study. Six surfacing stages emerged relative to the process of transition. Interestingly, The B.R.I.D.G.E. Theory of First-Time Fatherhood Transition Space describes how these fathers progress from the beholding, reorganizing, inhibiting, delivering, grasping, and embracing phases toward successful transition. This emerged theoretical model can be used in framing health care programs where the needs of fathers during this period are met and addressed. Finally, it can also be used in guiding nurses in their provision of a more empathetic care for first-time fathers.

Sorghum ergot is a disease caused commonly by C. africana. In 2015, ergot was identified for the first time in sorghum fields in Israel, leading to measures of eradication and quarantine. The aims of the study were to identify the ergot species by molecular and ergot alkaloid profile analysis, to determine the ergot alkaloid profile in pure honeydew and in infected sorghum silages and to estimate the safety of sorghum silages as a feed source. C. africana was rapidly and reliably identified by microscopical and molecular analysis. Dihydroergosine was identified as the major ergot alkaloid. Dihydrolysergol and dihydroergotamine were identified for the first time as significant ergot alkaloid components within the C. africana sclerotia, thereby providing for the first time a proof for the natural occurrence of dihydroergotamine. The sorghum silages were found to be safe for feed consumption, since the ergot alkaloids and the regulated mycotoxins were below their regulated limits.

The first-time NCLEX-RN(®) pass rate is considered by many to be the primary, if not sole, indicator of the quality of prelicensure nursing education programs. Used by state boards of nursing, educational program accreditors, and nursing faculty, the first-time NCLEX-RN pass rate influences important decisions about overall program quality, admission and progression policies, curricula, and teaching and learning practices. In this article, the authors call for a professional dialogue about the use of first-time pass rate (F-TPR) as an indicator of program quality, offer alternative methods for using the F-TPR as one measure of program quality, and suggest further research. One program's experience with low F-TPRs is offered as an exemplar of the unintended negative consequences that occur when the F-TPR is used as a sole criterion by a state board of nursing in judging a program's quality.
Tube feeding is an integral part of medical therapies, and can be easily managed also in the outpatient setting. Tube feeding by the stomach or small intestine with nasogastral or nasojejunal tubes is common in clinical practice. Long-term nutrition is usually provided through a permanent tube, i. e. a percutaneous endoscopic gastrostomy (PEG). Modern portable nutrition pumps are used to cover the patient's nutritional needs. Enteral nutrition is always indicated if patients can not or should not eat or if nutritional requirements cannot be covered within 3 days after an intervention, e. g. after abdominal surgery. Industrially produced tube feedings with defined substrate concentrations are being used; different compositions of nutrients, such as glutamine fish oil etc., are used dependent on the the condition of the patient. Enteral nutrition may be associated with complications of the tube, e. g. dislocation, malposition or obstruction, as well as the feeding itself, e. g.hyperglycaemia, electrolyte disturbances, refeeding syndrome diarrhea or aspiration). However, the benefit of tube feeding usually exceeds the potential harm substantially.

Dietary fibre is a mixture of various substances and is essential for maintaining appropriate intestinal functionality and it is currently considered to be a necessary part of a healthy diet. Current recommendations for fibre consumption by adults range from 20 to 35 g/day. Enteral nutrition is an emerging therapeutic variation in both hospital and domestic settings. To a great extent, this development has been made possible thanks to the design of new formulas that adapt better and better to the clinicla conditions or our patients. The type of fibre used in these preparations varies greatly. Some have only one source of fibre while others use differnet combinations. There are currently 32 formulas available on the Spanish market, without counting the modules or specific preparations of individual types of fibre. Despite the enormous advances in the knowledge of the beneficial effects of fibre, the fact of the matter is that enteral nutrition that we routinely prescribe in normal clinical practice does not contain fibre. The are several explanations for this, perhaps the most plausible is that these formulas may lead to problems in their administration and tolerance. It is necessary to choose the correct calibre of catheter and define the best infusion method and timing. Another difficulty may be the gastrointestinal tolerance of the formulas containing fibre. No large-scale problems of intolerance have however been described in healthy volunteers nor in patients with acute or chronic pathologies, although it is of fundamental importance to monitor the rhythm of depositions in all patients with enteral nutrition (EN) and ensure proper intake of liquids, which would also be useful to prevent occlusion of the catheter. The theoretical benefits of EN with fibre with a view to maintaining or improving normal intestinal structure and function are very varied. Nonetheless, it has noit yet been possible to prove many of these effects in controlled clinical trials. At the
There is growing evidence that we are now entering a new geological age defined by human influence on the planet, the Anthropocene. Millions of years from now, a stripe in the accumulated layers of rock on Earth's surface will reveal our human fingerprint just as we can see evidence of dinosaurs in rocks of the Jurassic, or the explosion of life that marks the Cambrian. There is now no part of the planet untouched by human influence. The realisation that we wield such planetary power requires a quite extraordinary shift in perception, fundamentally toppling the scientific, cultural and religious philosophies that define our place in the world. This session explores these issues and examines our new relationship with nature now that we so strongly influence the biosphere. And this session will look at what the impacts of our planetary changes mean for us, and how we might deal with the consequences of the Anthropocene we have created.

Childbirth is an anxiety-provoking event in a man's life. Therefore, strategies to decrease paternal anxiety during childbirth are necessary. This study determined the effects of music and satisfaction of first-time Filipino fathers during childbirth. In the study, a prospective quasi-experimental design was utilized. Ninety-eight purposive samples of first-time fathers were included in the study, 50 were allocated in the experimental group (music group) and 48 in the control group (nonmusic group) during the months of August to October 2013. Paternal anxiety and satisfaction were measured using the State Trait Anxiety Inventory and the Visual Analogue Scale for Satisfaction, respectively. Results revealed that the first-time fathers in the experimental group had lower State Trait Anxiety Inventory scores (p < .05) and higher Visual Analogue Scale for Satisfaction scores (p < .05) than those in the control group. Findings of the study provide substantial evidence to support the use of music in reducing anxiety and promoting satisfaction among first-time fathers during childbirth.

Appearance-related concerns are common following burns. However, there is minimal research that has specifically investigated patients' reactions when they looked in the mirror for the first time following facial burns. The current study aimed to investigate patients' reactions and factors associated with distress. Burns patients (n=35) who had sustained facial injuries completed a questionnaire which examined their reactions when looking in the mirror for the first time. Data were collected between April and July 2013. Participants had sustained their burns 12 months prior to participating, on average (ranging from one to 24 months). Forty-seven percent (n=16) of patients were worried about looking for the first time, 55% (n=19) were concerned about what they would see, and 42% (n=14) held negative mental images about what their faces looked like before they looked. Twenty-seven percent (n=9) of patients initially avoided looking, 38% (n=13) tried to 'read' others' reactions to them to try to gauge what they looked like, and 73% (n=25) believed that it was important for them to look. Mean ratings suggested that patients found the experience moderately distressing. Patients most often found the experience less distressing compared to their expectations. Distress was related to feeling less prepared, more worried and increased negative mental images prior to looking. In conclusion, patients' reactions to looking in the mirror for the first time vary. Adequately preparing patients and investigating their expectations beforehand is crucial. The findings have a number of important implications for practice.

Alcohol availability has been linked to drunk driving, but research has not examined whether this relationship is the same for first-time and repeat offenses. We examined the relationship between the business hours of alcohol outlets licensed to serve alcohol for on-premises consumption and misdemeanor-level (first offense) and felony-level drunk driving (repeat offense) charges in New York State in 2009. Longer outlet business hours were associated with more misdemeanor drunk driving charges, but were not associated with felony drunk driving charges. The per capita density of on-premises alcohol outlets did not affect misdemeanor or felony drunk driving charges. The results suggest that temporal alcohol availability may be an impelling factor for first-time drunk driving, but other factors likely influence repeat drunk driving behaviors.

We evaluated the effectiveness of a multicomponent package in training infant-care skills to first-time fathers. After developing and socially validating a set of infant-care skills, we assessed the effects of training in a hospital-based program with expectant fathers (Experiment 1) and in a home-based program with fathers having varied degrees of experience with their infants (Experiment 2). In both experiments, a multiple probe design demonstrated that the training package was responsible for producing criterion performance by the expectant and first-time fathers. A 1-month generalization probe in Experiment 1 showed that the effects transferred across training conditions (training doll to human infant) and settings (hospital to home). An increase in the number of infant-stimulation activities performed by fathers was also observed in both experiments. PMID:3771415

Breastfeeding has immense public health value for mothers, babies, and society. But there is an undesirably large gap between the number of new mothers who undertake and persist in breastfeeding compared to what would be a preferred level of accomplishment. This gap is a reflection of the many obstacles, both physical and psychological, that confront new mothers. Previous research has illuminated many of these concerns, but research on this problem is limited in part by the unavailability of a research instrument that can measure the key differences between first-time mothers and experienced mothers, with regard to the challenges they face when breastfeeding and the instructional advice they require. An instrument was designed to measure motivational complexity associated with sustained breast feeding behaviour; the Breastfeeding Motivational Measurement Scale. It contains 51 self-report items (7 point Likert scale) that cluster into four categories related to perceived value of breast-feeding, confidence to succeed, factors that influence success or failure, and strength of intentions, or goal. However, this scale has not been validated in terms of its sensitivity to profile the motivation of new mothers and experienced mothers. This issue was investigated by having 202 breastfeeding mothers (100 first time mothers) fill out the scale. The analysis reported in this paper is a three factor solution consisting of value, midwife support, and expectancies for success that explained the characteristics of first time mothers as a known group. These results support the validity of the BMM scale as a diagnostic tool for research on first time mothers who are learning to breastfeed. Further research studies are required to further test the validity of the scale in additional subgroups. PMID:24391731

Assessing risk of colorectal adenoma at first-time colonoscopy that are of higher likelihood of developing advanced neoplasia during surveillance could help tailor first-line colorectal cancer screening. We developed prediction models for high-risk colorectal adenoma (at least one adenoma ≥1 cm, or with advanced histology, or ≥3 adenomas) among 4,881 asymptomatic white men and 17,970 women who underwent colonoscopy as their first-time screening for colorectal cancer in two prospective U.S. studies using logistic regressions. C-statistics and Hosmer-Lemeshow tests were used to evaluate discrimination and calibration. Ten-fold cross-validation was used for internal validation. A total of 330 (6.7%) men and 678 (3.8%) women were diagnosed with high-risk adenoma at first-time screening colonoscopy. The model for men included age, family history of colorectal cancer, BMI, smoking, sitting watching TV/VCR, regular aspirin/NSAID use, physical activity, and a joint term of multivitamin and alcohol. For women, the model included age, family history of colorectal cancer, BMI, smoking, alcohol, beef/pork/lamb as main dish, regular aspirin/NSAID, calcium, and oral contraceptive use. The C-statistic of the model for men was 0.67 and 0.60 for women (0.64 and 0.57 in cross-validation). Both models calibrated well. The predicted risk of high-risk adenoma for men in the top decile was 15.4% vs 1.8% for men in the bottom decile (Odds Ratio[OR]=9.41), and 6.6% vs 2.1% for women (OR=3.48). In summary, we developed and internally validated an absolute risk assessment tool for high-risk colorectal adenoma among the U.S. population that may provide guidance for first-time colorectal cancer screening.

The changing role and practices of men as fathers is a growing subject of interest and debate within academic and everyday responses to contemporary sociocultural change. Prompted by questions about the production of identities and masculinities that accompanies social change, this paper is a psychosocial exploration of the identificatory positionings that are apparent in men's talk of becoming first-time fathers. Our qualitative analysis draws on a sample of 30 heterosexual and variously skilled men aged between 18 and 40 years in Norfolk (UK) who were interviewed as first-time fathers just before and after the birth of their child. We explore aspects of men's identifications within inter-generationally located biographies and associated social and relational contexts, specifically attending to ways in which men can make sense of a 'new' style of fatherhood, themselves and their masculinities in terms of being modern and traditional fathers. In adopting a psychosocial approach we are primarily concerned for ways in which the identificatory positions available to first-time fathers are conditional on a complex assemblage of dynamic mediations that are at once social, discursive and psychological.

Background Anemia is an important public health concern. Data from population-based surveys such as the National Health and Nutrition Examination Survey (NHANES) are the gold standard, but are obtained infrequently and include only small samples from certain minority groups. Objectives We assessed whether readily available databases of blood donor hemoglobin values could be used as a surrogate for population hemoglobin values from NHANES. Design Blood donor venous and fingerstick hemoglobin values were compared to 10,254 NHANES 2005-2008 venous hemoglobin values using demographically stratified analyses and ANOVA. Fingerstick hemoglobins or hematocrits were converted to venous hemoglobin estimates using regression analysis. Results Venous hemoglobin values from 1,609 first time donors correlated extremely well with NHANES data across different age, gender and demographic groups. Cigarette smoking increased hemoglobin by 0.26 to 0.59 g/dL depending on intensity. Converted fingerstick hemoglobin from 36,793 first time donors agreed well with NHANES hemoglobin (weighted mean hemoglobin of 15.53 g/dL for donors and 15.73 g/dL for NHANES) with similar variation in mean hemoglobin by age. However, compared to NHANES, the larger donor dataset showed reduced differences in mean hemoglobin between Blacks and other races/ethnicities. Conclusions Overall, first-time donor fingerstick hemoglobins approximate U.S. population data and represent a readily available public health resource for ongoing anemia surveillance. PMID:22460662

The egg-recognition processes underlying egg rejection are assumed to be based on an imprinting-like process (a female learning the aspect of her own eggs during her first breeding attempt). The imprinting-like process and the misimprinting costs have been the objective of many theoretical models and frequently have a leading role in papers published on brood parasitism; however, an experiment has never been undertaken to test the existence of this imprinting-like process by manipulating egg appearance in first-time breeding females. Here, we present the first such experimental study using the house sparrow (Passer domesticus), which is a conspecific brood parasite and which has a good ability to reject conspecific eggs, as a model species. We found that contrary to what the hypothesis predicts first-time breeding females did not reject their own eggs in their second breeding attempt. This lack of response against unmanipulated eggs could indicate that females have an innate preference for their own eggs. However, in a second experimental group in which first-time breeding females were allowed to learn the aspect of their (unmanipulated) own eggs, none ejected manipulated eggs during their second clutch either—a finding that does not support the idea of recognition templates being inherited, but instead suggests that recognition templates could be acquired again at each new breeding attempt. Our results demonstrate that it is likely that egg discrimination is not influenced by egg appearance in the first breeding attempt. PMID:23235707

Mexico has the second-highest prevalence of cesarean deliveries in the Americas, behind Brazil. Having had a previous cesarean delivery is highly predictive of having subsequent cesarean deliveries, yet evidence on the drivers of primary (that is, first-time) cesarean deliveries is sparse. Using 2014 Mexican birth certificate data and performing population-level analyses of data on 600,124 first-time mothers giving birth after at least thirty-seven weeks of gestation, we examined the prevalence and determinants of primary cesarean deliveries. We found a very high prevalence of cesarean deliveries among these women-48.7 percent-and wide variations across insurance coverage types. Enrollees in Seguro Popular, the public health insurance program introduced in 2003 for the previously uninsured and gradually rolled out nationally, had a cesarean rate of 40 percent, while women insured through the Social Security Institute for Civil Servants had a rate of 78 percent. The lower risk of primary cesarean deliveries among Seguro Popular enrollees persisted after adjustment for covariates. Rates of primary cesarean deliveries were particularly high in private birthing facilities for all first-time mothers. Reducing the rate of cesarean deliveries in Mexico will require interventions across types of insurance and birthing facilities and will also require targeted public health messaging.

This descriptive phenomenological study was designed to explore the life experiences of 14 Taiwanese first-time expectant fathers while their wives were in the third trimester of pregnancy. The authors used unstructured interviews to obtain the data from each participant. Data were analyzed by Colaizzi ' s (1978) method as a qualitative content analysis. In addition, the researcher used the work of Lincoln and Guba (1985) to enhance the rigorousness of this study. The findings demonstrated that during the third trimester of their wives ' pregnancy eight key themes emerged among the first-time expectant fathers, as follows: (1). Jubilation; (2). Feelings of uuncertainty (3). Adjustment; (4). Preparation for fatherhood; (5). Engagement; (6). Gender concerns; (7). The wonder of fetal movement, and (8). Expanded vision. The findings from this study have an important contribution to make to an advancement of practice, education and research concerning first-time fathers ' needs and aspirations. In addition, the findings showed that there is a need to reaffirm the place of caring in nursing and midwifery if our goal is to provide a high quality service which meets the needs of the woman and her family. It is essential for nurses to champion the advancement of family-centred care which involves their partners in pregnancy.

Microscopic enteritis (ME) is an inflammatory condition of the small bowel that leads to gastrointestinal symptoms, nutrient and micronutrient deficiency. It is characterised by microscopic or sub-microscopic abnormalities such as microvillus changes and enterocytic alterations in the absence of definite macroscopic changes using standard modern endoscopy. This work recognises a need to characterize disorders with microscopic and submicroscopic features, currently regarded as functional or non-specific entities, to obtain further understanding of their clinical relevance. The consensus working party reviewed statements about the aetiology, diagnosis and symptoms associated with ME and proposes an algorithm for its investigation and treatment. Following the 5(th) International Course in Digestive Pathology in Bucharest in November 2012, an international group of 21 interested pathologists and gastroenterologists formed a working party with a view to formulating a consensus statement on ME. A five-step agreement scale (from strong agreement to strong disagreement) was used to score 21 statements, independently. There was strong agreement on all statements about ME histology (95%-100%). Statements concerning diagnosis achieved 85% to 100% agreement. A statement on the management of ME elicited agreement from the lowest rate (60%) up to 100%. The remaining two categories showed general agreement between experts on clinical presentation (75%-95%) and pathogenesis (80%-90%) of ME. There was strong agreement on the histological definition of ME. Weaker agreement on management indicates a need for further investigations, better definitions and clinical trials to produce quality guidelines for management. This ME consensus is a step toward greater recognition of a significant entity affecting symptomatic patients previously labelled as non-specific or functional enteropathy.

Background Elevated serum 1,25-dihydroxyvitamin D (1,25(OH)2D) concentrations have been reported among cohorts of recurrent calcium (Ca) kidney stone-formers and implicated in the pathogenesis of hypercalciuria. Variations in Ca and vitamin D metabolism, and excretion of urinary solutes among first-time male and female Ca stone-formers in the community, however, have not been defined. Methods In a 4-year community-based study we measured serum Ca, phosphorus (P), 25-hydroxyvitamin D (25(OH)D), 1,25(OH)2D, 24,25-dihydroxyvitamin D (24,25(OH)2D), parathyroid hormone (PTH), and fibroblast growth factor-23 (FGF-23) concentrations in first-time Ca stone-formers and age- and gender frequency-matched controls. Results Serum Ca and 1,25(OH)2D were increased in Ca stone-formers compared to controls (P = 0.01 and P = 0.001). Stone-formers had a lower serum 24,25(OH)2D/25(OH)D ratio compared to controls (P = 0.008). Serum PTH and FGF-23 concentrations were similar in the groups. Urine Ca excretion was similar in the two groups (P = 0.82). In controls, positive associations between serum 25(OH)D and 24,25(OH)2D, FGF-23 and fractional phosphate excretion, and negative associations between serum Ca and PTH, and FGF-23 and 1,25(OH)2D were observed. In SF associations between FGF-23 and fractional phosphate excretion, and FGF-23 and 1,25(OH)2D, were not observed. 1,25(OH)2D concentrations associated more weakly with FGF-23 in SF compared with C (P <0.05). Conclusions Quantitative differences in serum Ca and 1,25(OH)2D and reductions in 24-hydroxylation of vitamin D metabolites are present in first-time SF and might contribute to first-time stone risk.

Previous studies have found a clear relationship between prolactin (prl) and paternal care in various vertebrate taxa. In New World monkeys, it has been demonstrated in several species that fathers have high prolactin levels even during periods without infant rearing. In this study, we followed the reproductive careers of common marmoset males as they transitioned from being an adult son within their native family to fathering their own offspring for the first time. Specifically, we examined the first experience of elevated prolactin levels in marmoset males. Additionally, we investigated the effects of the total number of experienced births as well as of age on prolactin levels. Our results show that common marmoset males did not experience an increase in prolactin secretion after pairing or shortly before birth of their first infants. However, prolactin levels rose more than twofold after the birth of their first infants and had lowered again 2.5 months after this event. We found no correlation between prolactin levels and the number of previous births experienced or age. Our study demonstrates that further work about a possible enhancing effect of prolactin on paternal care, by means of experimentally reducing hormonal levels, should be conducted in common marmosets using first-time fathers before males experience the first paternal increase in prolactin levels.

Objective Research demonstrates that punitive approaches to DWI employed by the judiciary have failed to significantly reduce recidivism. However, little is known about the deterrent effects of administrative and diversion sanctions. We examine whether such sanctions deter first-time DWI offenders. Methods We grouped combinations of administrative, judicial, and diversion sanctions routinely employed in the state of Maryland for processing drivers arrested for DWI into one of eight mutually exclusive disposition sequences. We applied this classification to Maryland drivers who had been licensed in the state and had precisely one DWI on their record prior to January 1, 1999. We then used a proportional hazards model to estimate the probability of remaining free of a new DWI during a 6-year period (January 1, 1999 – December 31, 2004) as a function of the disposition of the index violation, and of selected factors that could affect that probability. Results Drivers with a prior DWI were at relatively high risk of recidivating regardless of how they were sanctioned. Those who received administrative and alternative sanctions had a risk of recidivating similar to that of drivers who were convicted. Conclusion All dispositions sequences, not just convictions, indicate that first-time DWI offenders are at high risk of recidivating. PMID:21603059

Objectives. After conducting a media campaign focusing on the importance of oral and pharyngeal cancer (OPC) examinations, we assessed mechanisms of behavior change among individuals receiving an OPC examination for the first time. Methods. We used data from 2 waves of telephone surveys of individuals residing in 36 rural census tracts in northern Florida (n = 806). The second survey occurred after our media intervention. We developed media messages and modes of message delivery with community members via focus groups and intercept interviews. We performed a mediation analysis to examine behavior change mechanisms. Results. Greater exposure to media messages corresponded with heightened concern about OPC. Heightened concern, in turn, predicted receipt of a first-time OPC examination, but only among men. Conclusions. We extended earlier studies by measuring an outcome behavior (receipt of an OPC examination) and demonstrating that the putative mechanism of action (concern about the disease) explained the link between a media intervention and engaging in the target behavior. Improving the quality of media campaigns by engaging community stakeholders in selecting messages and delivery methods is an effective strategy in building public health interventions aimed at changing behaviors.

OBJECTIVE Substance use and delinquency among adolescents has been shown to be positively associated; however, the temporal relationship is not well understood. Examining the association between delinquency and substance use is especially relevant among adolescents with a first-time substance use related offense as they are at-risk for future problems. METHOD Data from 193 adolescents at time of diversion program entry and six months later was examined using cross-lagged path analysis to determine whether substance use and related consequences were associated with other types of delinquency across time. RESULTS Results demonstrated that delinquency at program entry was related to subsequent reports of heavy drinking and alcohol consequences, but not marijuana use or its consequences. In contrast, alcohol and marijuana use at program entry was not related to future reports of delinquency. CONCLUSIONS Findings emphasize the need to build in comprehensive assessments and interventions for youth with a first time offense in order to prevent further escalation of substance use and criminal behaviors.

Despite the growing incidence of child exploitation offences, there is little knowledge of the neuropsychological function of older child exploitation material offenders (CEMOs). Given that studies have reported that sex offenders demonstrate deficits attributed to frontal and temporal lobe function, the aim of this pilot study was to investigate the frontotemporal function of older first-time child exploitation material offenders (FTCEMOs). The neuropsychological performance of 11 older FTCEMOs was compared with 34 older historical sex offenders (HSOs) and 32 older nonsex offender (NSO) controls. Forty-five percent of FTCEMOs admitted to a pedophilic interest, which was significantly lower than those reported by HSOs. FTCEMOs provided significantly higher intellectual function scores than HSOs. Results revealed no evidence of mild or major neurocognitive disorder in FTCEMOs. Although the groups were not significantly different, compared with normative data, FTCEMOs reported a high incidence of impairment on a measure of decision making and on a measure of facial emotional recognition.

77 individuals convicted of a drinking and driving (DUI) offense were screened for recidivism approximately 12 years following their first offense. At the time of the initial DUI conviction, participants were administered the MAST and the MMPI-2. Participants' drinking history and driving history and arrest at the time of screening and at a 12-year follow-up were also reviewed. The results indicate that, among DUI recidivists, on average 6 years elapsed between their first and second DUI offenses. Driving history prior to the first DUI offense was predictive of later recidivism. The only significant finding from the MAST and MMPI results was that repeat offenders tended to have higher scores on the L and K validity scales of the MMPI. These results are discussed in the context of Jessor's Problem-Behavior Theory and as well their clinical implications for screening and treatment decisions involving first time DUI offenders.

This study examined the influence of social support on perceived stress and online support activities in two relationship contexts. In 2013, we surveyed 366 first-time mothers between the ages of 26 and 30 years from mainland China about their social support experiences with their mothers and mothers-in-law in regard to child rearing. Women who received higher levels of support from their mothers reported lower levels of perceived stress and higher levels of online support activities. Receiving support from mothers-in-law was not associated with either perceived stress or online support activities. The findings demonstrate the importance of considering relationship contexts when examining social support outcomes. Implications for future research on social support and interpersonal relationships are discussed.

SciPy is an effective tool suite for prototyping new algorithms. We share some of our experiences using it for the first time to support our research in object detection. SciPy makes it easy to integrate C code, which is essential when algorithms operating on large data sets cannot be vectorized. Python's extensive support for operator overloading makes SciPy's syntax as succinct as its competitors, MATLAB. Octave. and R. The universality of Python. the language in which SciPy was written, gives the researcher access to a broader set of non-numerical libraries to support GUI development. interface with databases, manipulate graph structures, render 3D graphics, unpack binary files, etc. More profoundly, we found it easy to rework research code written with SciPy into a production application, deployable on numerous platforms.

This study aims to investigate the predictive validity of externalizing psychopathology for persistence in delinquent behavior when controlling for socio-demographic and first arrest characteristics in childhood first-time arrestees. A sample of first-time arrestees aged under 12 (n = 192) was assessed using the Diagnostic Interview Schedule for Children (DISC-IV) parent-version on attention deficit/hyperactivity disorder (ADHD), oppositional defiant disorder (ODD) and conduct disorder (CD). Based on child and parent reports of offending as obtained at arrest and at 2-year follow-up, three groups of offenders were differentiated: (1) persistent high (n = 48), (2) occasional (n = 62), and (3) persistent low offenders (n = 82). Over one-third of the sample (33.9%) was diagnosed with an externalizing disorder, and 13.5% with both ADHD and ODD or CD. Higher levels of externalizing psychopathology distinguished persistent high offenders from occasional (comorbid ADHD and ODD/CD: OR 8.2, CI 2.6-25.5) and persistent low offenders (comorbid ADHD and ODD/CD: OR 18.2, CI 4.6-72.3; ADHD: OR 4.1, CI 1.3-13.0), over and above socio-demographic and first offense characteristics. Living with both biological parents distinguished the persistent low offenders from the occasional offenders (OR 2.5, CI 1.2-5.0). Since the prevalence of externalizing disorders was high and predicted re-offending, mental health screening and intervention initiatives, aiming at these conditions, should be investigated for this high-risk sample.

Objective Schizophrenia and/or antipsychotic drug use are associated with metabolic abnormalities; however, knowledge regarding metabolic status and physician’s monitoring of metabolic status at first schizophrenia diagnosis is sparse. We assessed the prevalence of monitoring for metabolic blood abnormalities and characterized the metabolic profiles in people with a first-time schizophrenia diagnosis. Methods This is a population-based cross-sectional study including all adults born in Denmark after January 1, 1955, with their first schizophrenia diagnosis between 2000 and 2012 in the Central Denmark Region. Information on metabolic parameters was obtained from a clinical laboratory information system. Associations were calculated using Wilcoxon rank-sum tests, chi-square tests, logistic regression, and Spearman’s correlation coefficients. Results A total of 2,452 people with a first-time schizophrenia diagnosis were identified, of whom 1,040 (42.4%) were monitored for metabolic abnormalities. Among those monitored, 58.4% had an abnormal lipid profile and 13.8% had an abnormal glucose profile. People who had previously filled prescription(s) for antipsychotic drugs were more likely to present an abnormal lipid measure (65.7% vs 46.8%, P<0.001) and abnormal glucose profile (16.4% vs 10.1%, P=0.01). Conclusion Metabolic abnormalities are common at first schizophrenia diagnosis, particularly among those with previous antipsychotic prescription(s). Increased metabolic abnormalities already present in the early phase of schizophrenia emphasize the need for increased monitoring and management. PMID:28280344

The Preventing Alcohol-Related Convictions (PARC) program is a novel educational curriculum for first-time DUI offenders, with the ultimate goal of reducing DUI recidivism. It differs from traditional DUI education and prevention programs in that it does not suggest to DUI offenders that they must abstain from alcohol entirely or control their drinking to prevent a future DUI; rather, it teaches students to prevent a future DUI by not driving their cars to drinking events. Thus, the emphasis of the curriculum is on controlling driving rather than controlling drinking to avoid future DUI convictions. The implementation of the program is ongoing throughout the state of Florida. The current randomized study focused on intermediate outcomes relevant for DUI recidivism; specifically, individuals' readiness for change regarding drinking and driving, and their endorsement of a PARC planning and action approach (controlling driving) versus a traditional approach (controlling drinking). The current research demonstrated that the PARC program is effective in moving participants toward more readiness for change and toward a strategy of planning ahead to avoid driving to any venue in which drinking may occur. Future research will assess the ultimate effect on DUI recidivism.

A study assessed the effects of victim impact panels (VIP) on first-time DWI (Driving While Intoxicated) offenders in Albuquerque, New Mexico. The VIP is an emotional presentation by the victim or their parents about how they were injured or their child was killed by a drunk driver. Subjects, 350 first-time offenders participated in a Mothers…

This study evaluated a multiple-family group-intervention program (MFGI) for first-time juvenile offenders. The recidivism rate for subjects who completed the MFGI (the Family Solutions Program) was compared to recidivism rates of two other groups of first-time juvenile offenders. Using logistic regression analysis predicting who will recidivate,…
Learning research through doing it often left me feeling confused, but I also experienced a well defined sense of 'well that's exactly what I thought all along', as I sought to clarify my uncertainties by turning to the literature. This feeling is, according to Schön & Bamberger, a type of historical revisionism where the student attributes insight to the moment when it occurs. They suggest that when the insight occurs, the 'moves on the way, tend to disappear' (1991, p207). This paper attempts to set down these moves and concludes with an exhortation to keep educational research rooted in the experience and interest of the student.
This article discusses men's transition to first time fatherhood, with a focus on the way they recognise various in-tension moral demands and negotiate an appropriate role for themselves. The findings are taken from a longitudinal study, drawing on elements of grounded theory, comprising a series of face-to-face and telephone interviews with 11 men over a 9-month period from the 12th week of pregnancy to 8 weeks after the birth. The analysis focuses on men's feelings and experience of exclusion and participation, and their response and reaction to that experience. The findings present two descriptive themes, ‘on the inside looking in’ and ‘present but not participating’, followed by third theme ‘deference and support: a moral response’ that exposes the dilemmatic nature of men's experience and explains the participants’ apparent acceptance of being less involved. The discussion explores the concept of moral residue, arguing that while deference and support may be an appropriate role for fathers in the perinatal period it may also be a compromise that leads to feelings of uncertainty and frustration, which is a consequence of being in a genuinely dilemmatic situation.

Culturally and linguistically appropriate interventions are needed to reduce the risk of driving under the influence (DUI) recidivism among diverse populations. Using core elements of Motivational Interviewing, we developed a culturally relevant web-MI intervention (web-MI) in English and Spanish to serve as a standalone or adjunctive program in DUI educational settings and evaluated its feasibility and acceptability among clients with first-time DUI offenses. We conducted an iterative formative assessment using focus groups with staff (n = 8) and clients (n = 27), and usability interviews with clients (n = 21). Adapting MI for the web was widely accepted by staff and clients. Clients stated the web-MI was engaging, interactive and personal, and felt more comfortable than past classes and programs. Spanish-speaking clients felt less shame, embarrassment, and discomfort with the web-MI compared to other in-person groups. Results support the viability of web-MI for DUI clients at risk for recidivism and highlight the importance of adapting the intervention for diverse populations. Key decisions used to develop the web-MI are discussed.

Results of semistructured interviews with 45 pregnant unmarried first-time African American mothers indicated a wide range of expectancies concerning the coparenting relationship they would develop with others once their baby arrived. Most common coparenting systems projected by respondents involved maternal grandmothers and/or the babies' fathers, though other caregivers were explicitly anticipated in a smaller number of cases. Multiperson coparenting systems were the norm, and only 2 of 45 respondents anticipated that they would be entirely on their own with no coparental system whatsoever. Qualitative analyses of mothers' narratives about postbaby coparenting systems revealed five main constructions: having thought about and anticipating coparenting, positive in outlook; having thought about and anticipating coparenting, but with mild concerns (conflict, unreliability); having thought about coparenting and anticipating limited or no support; having thought about coparenting and anticipating significant conflict and nonsupport; and having not thought much about coparenting, being neither focused on nor worried about this issue. Illustrations of each of these types are provided, and directions for family science and practice are discussed.

Bluetongue is endemic in India and has been reported from most Indian states. Of late, the clinical disease is most frequently seen in the states of Andhra Pradesh, Telangana (erstwhile Andhra Pradesh state), Tamil Nadu and Karnataka. Our analysis of diagnostic samples from bluetongue outbreaks during 2010-2011 from the state of Karnataka identified bluetongue virus (BTV) serotype 5 (BTV-5) for the first time in India. One of the diagnostic samples (CH1) and subsequent virus isolate (IND2010/02) contained both BTV-2 and BTV-5. Segment 2 (seg-2) sequence data (400 bp: nucleotides 2538-2921) for IND2010/02-BTV5, showed 94.3% nucleotide identity to BTV-5 from South Africa (Accession no. AJ585126), confirming the virus serotype and also indicating that Seg-2 was derived from a Western topotype, which is in contrast to serotype 2, that belongs to an Eastern topotype. BTV-5 has been recently reported from Africa, China, French islands and the Americas. Although the exact source of the Indian BTV-5 isolate is still to be confirmed, recent identification of additional exotic serotypes in India is of real concern and might add to the severity of the disease seen in these outbreaks.
The experience in a psychiatric residency of being a psychotherapist for the first time can be overwhelming and anxiety-provoking. This paper examines a first psychotherapy case which utilizes a theory-distant approach based on the use of metaphor. Metaphorical theory is reviewed, and potential benefits and pitfalls of using metaphor are examined. An in-depth case study is done, focusing on the following six metaphors: Art as Psychotherapy; Psychotherapy as Art; The World Is a Trap; Mothers Are Martyrs; StepMothers Are Evil; and Artists Are Crazy. Each metaphor was utilized in multiple layers through the course of the therapy. Some of the current research in the use of metaphor in psychotherapy is reviewed. Through this approach, I was able to develop necessary psychotherapeutic skills without being overwhelmed by traditional theories such as Freudian, Object Relations or Self Psychology. I conclude that the use of metaphor with my first psychotherapy patient strengthened the therapeutic alliance, allowed an idiosyncratic language to develop in the therapy, structured recurrent themes, and permitted me to respect the patient's defenses.

First human administration of a new chemical entity (NCE) constitutes a critical step in drug development. The primary objective of such a study is the assessment of the shortterm safety and tolerability of single and multiple doses of the NCE in healthy volunteers. Secondary objectives are to obtain preliminary data on the pharmacokinetics and pharmacodynamics using surrogate or biornarkers of the beneficial as well as the adverse effects of the drug. Interpretation of safety data should be cautious and mainly based on comparisons with placebo. A special focus should be made on the assessment of adverse events, liver enzymes, and cardiac repolarization. Well-designed, first-time-to-man studies should determine the safety of the NCE in humans and predict the dose range that may be used to safely and accurately conduct further clinical trials in the target patient population based on safety data (maximum tolerated dose), pharmacodynamics (minimum active dose, duration of action, and dosage regimen), and pharmacokinetics (dosage regimen).

The experience of hospital inpatient stays at childbirth was studied in a longitudinal study of the experiences of 96 first-time parents during the transition to parenthood. For women, the prospect of birth was a major worry during pregnancy. Negative expectations proved in general to be justified by events, with many women reporting predominantly bad memories of the experience. Satisfaction with the hospital inpatient stay is also considered: a major source of dissatisfaction was inadequate help with breast feeding, which produced many difficulties. Middle class mothers were in general more dissatisfied with their hospital stay, as were women who had Caesarean births. Relationships were found between antenatal class attendances and the likelihood of a normal delivery and reported pain during childbirth. The role and experience of fathers was also considered. Most expected to be at the birth from an early stage in pregnancy; more than two-thirds were present for the delivery and half or more at the labour. Their experience at this time was more positive than that of their partners. But during the hospital stay, this role was much more marginal. The results are discussed in terms of their implications for antenatal preparation, breast feeding and paternal involvement.

This study aimed to examine the transition to parenthood and mental health in first-time parents in detail and explore any differences in this transition in the context of parental gender and postpartum mental health. Semistructured clinical interviews (Birmingham Interview for Maternal Mental Health) were carried out with 46 women and 40 men, 5 months after birth. Parents were assessed on pre- and postpartum anxiety, depression, and postpartum posttraumatic stress disorder (PTSD), and a range of adjustment and relationship variables. One fourth of the men and women reported anxiety in pregnancy, reducing to 21% of women and 8% of men after birth. Pregnancy and postpartum depression rates were roughly equal, with 11% of women and 8% of men reporting depression. Postpartum PTSD was experienced by 5% of parents. Postpartum mental health problems were significantly associated with postpartum sleep deprivation (odds ratio [OR] = 7.5), complications in labor (OR = 5.1), lack of postpartum partner support (OR = 8.0), feelings of parental unworthiness (OR = 8.3), and anger toward the infant (OR = 4.4). Few gender differences were found for these variables. This study thus highlights the importance of focusing interventions on strengthening the couple's relationship and avoiding postnatal sleep deprivation, and to address parents' feelings of parental unworthiness and feelings of anger toward their baby.

For the first time some excellent pieces belonging to the majolica production of the great master Giorgio Andreoli from Gubbio (Central Italy) have been characterized from a chemical and structural point of view with the aim to identify the composition of both pigments and lustres. A series of particle-induced X-ray emission (PIXE), Rutherford backscattering spectrometry (RBS) and Raman analyses have been performed on some plates coming from Museo del Palazzo dei Consoli (Gubbio) and several French museums (Louvre, Musée National de la Céramique, Musée National de la Renaissance) lustred by Giorgio Andreoli and decorated by famous majolica painters such as Francesco Xanto Avelli. The three techniques are complementary and useful in the investigation of art objects since they are non-destructive. Furthermore, the low detection limits allow the identification of all elements and compounds present, and RBS allows concentration profiling, too. It is worth noticing that the examined objects are characterized by the presence of both gold and ruby-red lustres, a peculiarity of Mastro Giorgio’s technique. The measurements by PIXE and RBS have been carried out on the AGLAE accelerator at C2RMF, Louvre Palace.

Objective To describe the use of social media during the antepartum and postpartum periods among first-time African American mothers and their support persons. Design A qualitative critical ethnographic research design within the contexts of Family Life Course Development Theory and Black Feminist Theory. Setting Participants were recruited from community-based, public health, and home visiting programs. Participants A purposive sample was recruited, consisting of 14 pregnant African American women and eight support persons. Methods Pregnant and postpartum African American women and their support persons were interviewed separately during the antepartum and postpartum periods. Data were analyzed thematically. Results Participants frequently used social media for educational and social support and searched the internet for perinatal and parenting information. Most participants reported using at least one mobile application during their pregnancies and after giving birth. Social media were typically accessed through smartphones and/or computers using different websites and applications. While participants gleaned considerable information about infant development from these applications, they had difficulty finding and recalling information about infant feeding. Conclusion Social media are an important vehicle to disseminate infant feeding information; however, they are not currently being used to full potential. Our findings suggest that future interventions geared towards African American mothers and their support persons should include social media approaches. The way individuals gather, receive, and interpret information is dynamic. The increasing popularity and use of social media platforms offers the opportunity to create more innovative, targeted mobile health interventions for infant feeding and breastfeeding promotion.

Driving while impaired (DWI) is a grave and persistent high-risk behavior. Previous work demonstrated that DWI recidivists had attenuated cortisol reactivity compared to non-DWI drivers. This suggests that cortisol is a neurobiological marker of high-risk driving. The present study tested the hypothesis that this initial finding would extend to first-time DWI (fDWI) offenders compared to non-DWI drivers. Male fDWI offenders (n = 139) and non-DWI drivers (n = 31) were exposed to a stress task, and their salivary cortisol activity (total output and reactivity) was measured. Participants also completed questionnaires on sensation seeking, impulsivity, substance use, and engagement in risky and criminal behaviors. As hypothesized, fDWI offenders, compared to non-DWI drivers, had lower cortisol reactivity; fDWI offenders also showed lower total output. In addition, cortisol activity was the most important predictor of group membership, after accounting for alcohol misuse patterns and consequences and other personality and problem behavior characteristics. The findings indicate that attenuated cortisol activity is an independent factor associated with DWI offending risk at an earlier stage in the DWI trajectory than previously detected. PMID:25922575
English language education officially started in Japanese elementary schools in 2009. Homeroom teachers, whether experienced or not, are responsible for teaching the subject to students. Additionally, teachers are often required to team-teach with a native English speaker. It is plausible that Japanese teachers are anxious about teaching English.…

Canine parvovirus (CPV) enteritis has, since its emergence in 1978, remained a common and important cause of morbidity and mortality in young dogs. The continued incidence of parvoviral enteritis is partly due to the virus' capability to evolve into more virulent and resistant variants with significant local gastrointestinal and systemic inflammatory sequelae. This paper reviews current knowledge on historical-, signalment-, and clinical factors as well as several haematological-, biochemical- and endocrine parameters that can be used as diagnostic and prognostic biomarkers in CPV enteritis. These factors include season of presentation, purebred nature, bodyweight, vomiting, leukopaenia, lymphopaenia, thrombocytopaenia, hypercoagulability, hypercortisolaemia, hypothyroxinaemia, hypoalbuminaemia, elevated C-reactive protein and tumour necrosis factor, hypocholesterolaemia and hypocitrullinaemia. Factors contributing to the manifestations of CPV infection are multiple with elements of host, pathogen, secondary infections, underlying stressors and environment affecting severity and outcome. The availability of several prognosticators has made identification of patients at high risk of death and their subsequent targeted management more rewarding.

A 76-year-old man had small bowel obstruction and organic small bowel disease following a series of bizarre massive gustatory insults that involved food, medications, and mega-mineral-vitamin supplements. Intestinal obstruction required partial small bowel resection. The dietary indiscretions resulted in severe enteritis (indiscretion enteritis). The sequence has been termed a Rabelaisian syndrome after the great French writer and physician, Francois Rabelais, who vividly described bizarre gustatory habits. Gut injury may result from unwise oral intake of various foods and mineral supplements.

Background and Objective: Photobacterium damselae subsp. damselae is a marine pathogenic bacterium which causes disease in marine animals and human. This bacterium mostly found in coastal shallow seawater. So, the aim of this study was isolation and characterization of Photobacterium damselae subsp. damselae from edible fish of Persian Gulf, Bandar Abbas. Material and Methods: Totally 100 fish from different species were evaluated and out of that 5 different types of fish with external symptoms including: Caranx sexfasciatus, Lethrinus olivaceus, Scomberoid tol, Auxis thazard and Liza macrolepis, were collected from Bandar Abbas local fish market in September 2013. The samples were cultured on Marin Agar 2216 and Thiosulfate Citrate Bile salts Sucrose Agar media and incubated at 25°C for 48 hrs. Then the isolates were characterized using biochemical (API 20 NE system) and molecular techniques. In addition, antibiotic susceptibility, presence of poly β hydroxy butyrate and hemolysis activity of isolates were evaluated. Results and Conclusion: Entirely, 30 Gram negative bacterial colonies were isolated from the selected fish. Among the isolates, two suspected colonies were identified as Photobacterium damselae from Caranx sexfasciatus with API 20NE biochemical test. This results confirmed by 16s rRNA sequencing method. Both isolates showed α hemolytic with existence of β hydroxyl butyrate. Furthermore, the isolates were susceptible to ciprofloxacin, chloramphenicol and nalidixic acid. Conclusion: Overall, the study indicated first time isolation of this bacterium from one type of fish caught from Persian Gulf, which warns us to pay more attention to fishery in this geographical area.

AIM: To investigate possible disparities in perioperative morbidity and mortality among different body mass index (BMI) groups and to simulate the impact that these differences might have had on the cohort of patients undergoing cadaveric liver transplantation (LT). METHODS: All adult recipients undergoing first time LT for benign conditions and receiving a whole graft from brain-dead donors were selected from the united network of organ sharing registry. From January 1994 to June 2013, 48281 patients satisfied the inclusion criteria and were stratified by their BMI. The hypothesis that abnormal BMIs were independent predictors of inferior outcomes was tested with univariate and multivariate regression analyses. RESULTS: In comparison to normal weight recipients, underweight and morbidly obese recipients had increased 90-d mortality (adjusted OR = 1.737; 95%CI: 1.185-2.548, P = 0.005) (adjusted OR = 1.956; 95%CI: 1.473-2.597, P = 0.000) respectively and inferior patients’ survivals (adjusted HR = 1.265; 95%CI: 1.096-1.461, P = 0.000) (adjusted HR = 1.157; 95%CI: 1.031-1.299, P = 0.013) respectively. Overall, patients’ 5-year survival were 73.9% for normal-weight, 71.1% for underweight, 74.0% for overweight, 74.4% for class I obese, 75.0% for class II obese and 71.5% for class III obese recipients. Analysis of hypothetical exclusion of underweight and morbidly obese patients from the pool of potential LT candidates would have improved the overall survival of the entire cohort by 2.7% (95%CI: 2.5%-3.6%). CONCLUSION: Selected morbidly obese patients undergoing LT for benign conditions had 5-year survival rates clinically comparable to normal weight recipients. Impact analysis showed that exclusion of high-risk recipients (underweight and morbid obese patients) would not significantly improve the overall survival of the entire cohort of patients requiring LT.

Aim To gain a deeper understanding of first-time parents' experiences of early discharge from hospital after delivery and home-based postnatal care. Material and methods The study was comprised of focus group interviews, interviews with couples and with fathers. Twenty-one parents participated. Inclusion criteria: healthy women who have given birth to their first child after a normal pregnancy and delivery, the women's partners, healthy and full term babies, Swedish-speaking, discharge from the delivery ward within 24 hours, resident in the Uppsala community, the parents cohabited at the time of the delivery. The material was analysed by qualitative content analysis. Results Three themes emerged: The family's strategy, which describes the family's expectations of postnatal care and their experiences of the real situation. Some are flexible concerning going home early, and others have decided in advance. Self-reliance and strength, which explores the parents' feelings of security and uncertainty, freedom and independence, and shared responsibility. Breast-feeding is described as the ‘main thing’, an interactive learning process. Professional support in the home summarizes the parents' experience of the midwife's support at home. While conflicting feelings may be revealed during the first days, the midwife confirms their new roles as parents. The midwife is seen as a support and adviser to the parents. Conclusion This study shows that parents welcome home-based postnatal care with professional support from midwives. We conclude that this care suits healthy families. We think it will be more important in the future to discriminate between healthy families and those in need of hospital care, than to focus on the moment when they leave the hospital, early or late.

Although intra-aortic balloon pumping (IABP) has been used widely as a routine cardiac assist device for perioperative support in coronary artery bypass grafting (CABG), the optimal timing for high-risk patients undergoing first-time CABG using IABP is unknown. The purpose of this investigation is to compare preoperative and preventative IABP insertion with intraoperative or postoperative obligatory IABP insertion in high-risk patients undergoing first-time CABG. We reviewed our IABP patients' database from 2002 to 2007; there were 311 CABG patients who received IABP treatment perioperatively. Of 311 cases, 41 high-risk patients who had first-time on-pump or off-pump CABG (presenting with three or more of the following criteria: left ventricular ejection fraction less than 0.45, unstable angina, CABG combined with aneurysmectomy, or left main stenosis greater than 70%) entered the study. We compared perioperatively the clinical results of 20 patients who underwent preoperative IABP placement (Group 1) with 21 patients who had obligatory IABP placement intraoperatively or postoperatively during CABG (Group 2). There were no differences in preoperative risk factors, except left ventricular aneurysm resection, between the two groups. There were no differences in indications for high-risk patients between the two groups. The mean number of grafts was similar. There were no significant differences in the need for inotropes, or in cerebrovascular, gastrointestinal, renal, and infective complications postoperatively. There were no IABP-related complications in either group. Major adverse cardiac event (severe hypotension and/or shock, myocardial infarction, and severe hemodynamic instability) was higher in Group 2 (14 [66.4%] vs. 1 [5%], P < 0.0001) during surgery. The time of IABP pumping in Group 1 was shorter than in Group 2 (72.5 +/- 28.9 h vs. 97.5 +/- 47.7 h, P < 0.05). The duration of ventilation and intensive care unit stay in Group 1 was significantly shorter

Introduction: We performed first-time scientific comet observations from Tübitak National Observatory (TUG), Turkey using two telescopes of that facility. In order to test the capabilities of the instruments, we performed a long comet-monitoring campaign from October 2013 to January 2014. We observed many comets, including but not limited to C/2012 S1 ISON, 154P Brewington, and C/2013 R1 Lovejoy. All comets were monitored for several nights with the Bessel R, V, and B filters from the 1-m (T100) and 1.5-m (RTT150) telescopes. Additionally, we acquired the first spectroscopic observations of a comet from TUG, using the TUG Faint Object Spectrograph (TFOSC with grism between 3230-9120 Å) mounted on RTT150. With these observations, we could assess the quality of the TUG instruments for cometary science, and identified a few limitations. We propose some technical improvements for future comet observations. These will open new observational opportunities for Turkish astronomers and a participation in international campaigns on cometary science. Observations and simulations: Apart from testing the instruments, our observations were also driven by the scientific questions regarding comet ISON around its perihelion passage. We intended to follow the formation and evolution of dust coma structures, and use well-tested models to simulate and understand this activity (Vincent et al. 2010, 2013, Lin et al. 2012). Additionally, we wanted to acquire spectra and derive the composition of the tail before and after perihelion. Unfortunately, the comet was not very active before perihelion and completely disintegrated at the end of November 2013. Nonetheless, we had acquired many images in the previous weeks, and we used the remaining nights to monitor other comets, mainly C/2013 R1 Lovejoy. Since the observatory is not equipped with the comet gas filters, we concentrated on dust structures and monitored comet ISON during October 2013 in Bessel R, B, and V filters. The cometary

-HDL-cholesterol (p<.001), triglyceride/HDL ratio (p=0.002), glucose (p=0.02), insulin (p=0.02), and HOMA-IR (p=0.03) increased significantly. With quetiapine, cholesterol (p<0.05), triglycerides (p=0.01), non-HDL-cholesterol (p=0.03), and triglyceride/HDL ratio (p=0.004) increased significantly. With risperidone, triglycerides (p=0.04) increased significantly. Metabolic baseline-to-endpoint changes were non-significant with aripiprazole and comparison subjects. Dyslipidemia developed in 28.9% (n=13), 19.4% (n=26), 8.8% (n=3), and 7.3% (n=3) of youth on olanzapine, risperidone, quetiapine and aripiprazole, and 6.7% (n=1) of comparison subjects (p=0.03), while acquired insulin resistance (HOMA-IR>4.39: 2.9%–17.8%) and metabolic syndrome (0%–6.5%) were relatively rare in this short-term study. Conclusions First time SGA use was associated with significant weight gain with each medication. Metabolic changes varied among the 4 antipsychotics. PMID:19861668

Two apparently novel viral gastroenteritides of dogs were recognized in 1978: one caused by a parvo-like virus (CPV) and one by a corona-like virus (CCV). A rotavirus has also been tentatively associated with neonatal pup enteritis. Canine viral enteritis is characterized by a sudden onset of vomiting and diarrhea, rapid spread and high morbidity. Treatment is only supportive but must be initiated promptly. Infected animals should be isolated immediately; the extremely contagious nature of these diseases makes them difficult to contain. Feces from infected dogs appear to be the primary means of transmission. Sodium hypochlorite solutions (eg, Clorox) are recommended for disinfection. The development of effective vaccines is an immediate and pressing problem.

Radiation enteritis is defined as the loss of absorptive capacity of the intestine following irradiation, which is most commonly seen after radiotherapy for pelvic and abdominal malignancies. It is divided into acute and chronic forms and usually presents with diarrhea and malabsorption. Malnutrition is a common complication of chronic radiation enteritis (CRE). We reviewed the etiology, prevalence, symptoms, diagnosis and management of CRE and CRE with malnutrition in this article. Functional short bowel syndrome as a cause of malnutrition in CRE is also considered. The diagnostic work-up includes serum markers, endoscopy, cross-sectional imaging and the exclusion of alternative diagnoses such as recurrent malignancy. Management options of CRE include dietary manipulation, anti-motility agents, electrolyte correction, probiotics, parenteral nutrition, surgical resection and small bowel transplantation. Treatment may also be required for coexisting conditions including vitamin B12 deficiency, bile acid malabsorption and depression.

Cyclophosphamide is a potent cytotoxic agent used in many clinical settings. The main risks of cyclophosphamide therapy include hematological disorders, infertility, hemorrhagic cystitis and malignancies. Gastrointestinal side effects reported to date are often non-specific and not severe. We present the first case of a fatal small bowel enteritis and pan-colitis which appears to be associated with cyclophosphamide.

Astronaut John H. Glenn Jr. enters his Mercury capsule, 'Friendship 7' as he prepares for launch of the Mercury-Atlas rocket. On February 20, 1962 Glenn lifted off into space aboard his Mercury Atlas 6 (MA-6) rocket and became the first American to orbit the Earth. After orbiting the Earth 3 times, Friendship 7 landed in the Atlantic Ocean 4 hours, 55 minutes and 23 seconds later, just East of Grand Turk Island in the Bahamas. Glenn and his capsule were recovered by the Navy Destroyer Noa, 21 minutes after splashdown.

When compared with the general United States child population, children entering foster care have elevated rates of mental health problems. This study examines: (1) state approaches to mental health evaluations for children entering foster care for the first time, (2) the consistency of these approaches with professional guidelines, and (3) whether the specific instruments endorsed are supported by available evidence. Semi-structured qualitative interviews and a document review of available protocols/policies were conducted for 47 states and the District of Columbia. All states endorsed mental health evaluations; variation existed between states in approach, timeframe, administrator, and specific instruments endorsed.

This article examines the prediction of recidivism using the Global Risk Assessment Device (GRAD), a reliable and valid measure of dynamic factors associated with family characteristics, peers, mental health, substance abuse, trauma exposure, educational concerns, accountability, and health risks. Using a sample of adult caregivers of first-time misdemeanant offenders, two factors-education and accountability-were significantly associated with recidivistic behavior, supporting the use of GRAD data in correctly identifying first-time offenders who have the greatest and the least likelihood for future offending behavior. Additional analyses utilizing parent reports on African American males indicate that the GRAD provides discrimination in the prediction of recidivism in a group typically seen as being high risk simply because of their gender and race. The assessment drives intervention approach of the GRAD is discussed in terms of using reports from adults to accurately place youth into appropriate levels of supervision and treatment.

Somatic growth and reproduction were examined in individual laboratory-grown female Gambusia affinis fed with high (H), medium (M) and low (L) ration levels from birth to the first-time spawning. Results showed that the body length and weight, condition factor (CF), wet weight gain (WGw), specific growth rate in wet weight (SGRw) and ration levels in terms of energy (RLe) decreased significantly (p < 0.05) with decreasing ration levels from birth to first-time spawning. On the contrary, the food conversion efficiency in terms of energy (FCEe) increased significantly (p < 0.05) with the decreasing ration levels from birth to first-time sexual maturity. Furthermore, higher percentages of energy intake from food were allocated to somatic and gonad growth in M and L groups compared to the H group before sexual maturity; In addition, the time for first-time spawning in groups M and L was longer than that of the H group. As a result, the gonad-somatic index (GSI) and oocytes/embryos weight in M and L groups were similar to that of the H group, although the ovary weight and oocytes/embryos numbers were all lower than that of the H group. Also, similar growth performances were observed in second-generation offspring, which were produced by female parents fed with different ration levels. These findings suggest that the female G. affinis could produce a number of healthy offspring under conditions of food restriction, and that this could be achieved by increasing the energy allocated to gonad development, reducing fecundity and delaying spawning time. These life strategies ensured that G. affinis could survive and thrive in adverse environmental conditions and exhibit characteristics of invasive fish species. PMID:25768343

Five pediatric patients with acute traumatic "first-time" lateral patellar dislocations were successfully reduced using a novel, atraumatic, and simple technique. Uniquely, unlike the traditional method of patellar reduction, the patellar dislocations were reduced without any direct manipulation of the patella. In co-operative patients, no analgesia was required. Further validation of the reproducibility of the effectiveness of this method for successful patellar reduction in pediatric and adult populations are required.

This research has focused on the birthing experience of first-time mothers who received the narcotic analgesic combination of Pethidine and Hydroxyzine during the first stage of labour. A qualitative research methodology was used to collect data. Unstructured interviews were held with first-time mothers to obtain accounts of their experience of childbirth. These narrations were audio-taped while the participants were still being cared for in the postnatal ward of the hospital where delivery took place. Nine interviews were conducted with first-time mothers who gave birth normally vaginally after a normal pregnancy and who received a narcotic analgesic in the first stage of labour. The transcribed interviews were analyzed using Tesch's method of descriptive analysis (in Creswell, 1994:115). Four themes with sub-themes emerged from the analysis. The participants reported on the physical experience of labour and described experiencing a lot of pain for which analgesics were given. They also described how these drugs dulled the pain but made them sleepy and unable to cooperate with the midwives. They described their emotional experiences, which included joy and happiness as well as anxiety, anger and despondence. They also reported that they were not sufficiently informed about labour and child-birth. In the last theme they described the methods they used to help them cope with labour including distracting techniques, leaning on a supportive person or praying. Guidelines to help midwives overcome these problems were developed.

Objectives. We identified individual and contextual factors associated with referral and enrollment in home visiting among at-risk, first-time mothers. Methods. We retrospectively studied referral and enrollment in a regional home visiting program from 2007 to 2009 in Hamilton County, Ohio. Using linked vital statistics and census tract data, we obtained individual and community measures on first-time mothers meeting eligibility criteria for home visiting (low income, unmarried, or age < 18 years). Generalized linear modeling was performed to determine factors associated with relative risk (RR) of (1) referral to home visiting among eligible mothers and (2) enrollment after referral. Results. Of 8187 first-time mothers eligible for home visiting, 2775 were referred and 1543 were enrolled. Among referred women, high school completion (RR = 1.10) and any college (RR = 1.17) compared with no high school completion were associated with increased enrollment, and enrollment was less likely for those living in communities with higher socioeconomic deprivation (RR = 0.71; P < .05). Conclusions. Barriers to enrollment in home visiting persisted at multiple ecological levels. Ongoing evaluation of enrollment in at-risk populations is critical as home visiting programs are implemented and expanded. PMID:24354835

Aortic graft fistula is a rare and life-threatening complication after aortic reconstruction. The incidence ranges from 0.5 to 4%, and even if the diagnosis and treatment is appropriate, the results of surgery are poor: mortality rate ranges from 14 to 70%. The optimal method of treatment is still controversial; prosthetic removal and extra-anatomic bypass has been advocated as the standard method, but more recently, because the high mortality rate associated with this procedure, some have prompted to recommend in situ aortic graft replacement as a more successful treatment. Personal experience with incidence (0.7%) outcome and mortality (57%) in 7 patients treated over a period of 6 years (1990-1996) is reported. Results from this group are compared with another group (6 patients) previously treated (1975-1982) for the same pathology. Our results after 10 years, show the same incidence (0.7 vs 0.6%) and an elevated and unchanged mortality (57 vs 66%). Better results in the management of aorto-enteric fistulas could be achieved with the removal of infected infrarenal aortic prosthetic grafts and in situ homografts replacement.
Conventional wisdom has it that the best way to do business in China is through an equity joint venture (EJV) with a well-connected Chinese partner. But pioneering companies are starting a trend toward a new way to enter that market: as a wholly foreign-owned enterprise, or WFOE. Increasingly, says the author, joint ventures do not offer foreign companies what they need to succeed in China. For example, many companies want to do business nationally, but the prospects for finding a Chinese partner with national scope are poor. Moreover, there are often conflicting perceptions between partners about how to operate an EJV: Chinese companies, for example, typically have a more immediate interest in profits than foreign investors do. By contrast, the author asserts, WFOEs are faster to set up and easier to manage; and they allow managers to expand operations more rapidly. That makes them the perfect solution, right? The answer is a qualified yes. First, foreign companies will still need sources of guanxi, or social and political connections. Second, managers must take steps to avoid trampling on China's cultural or economic sovereignty. Third and perhaps most important, foreign companies must be prepared to bring something of value to China-usually in the form of jobs or new technology that can help the country develop. Companies willing to make the effort, says the author, can reap the rewards of China's burgeoning marketplace.

In this paper, polymethacrylate enteric coated materials based on the equal mass of methyl acrylic acid and ethyl acrylate as the main raw materials were synthesized through emulsion polymerization. Omeprazole Enteric-coated Capsules were prepared by the fluidized bed coating technology using above materials as enteric layer and in vitro enteric test was considered according to standard. The results showed that the material had good coverage in the surface of omeprazole isolated pellets, excellent acid resistance in artificial gastric acid environment, and reached the disintegration effect in the buffer solution of 20min. Moreover the drug release reached 88.2% and had excellent long-term storage.

Background Environmental enteric dysfunction (EED) refers to an incompletely defined syndrome of inflammation, reduced absorptive capacity, and reduced barrier function in the small intestine. It is widespread among children and adults in low- and middle-income countries. Understanding of EED and its possible consequences for health is currently limited. Objective A narrative review of the current understanding of EED: epidemiology, pathogenesis, therapies, and relevance to child health. Methods Searches for key papers and ongoing trials were conducted using PUBMED 1966–June 2014; ClinicalTrials.gov; the WHO Clinical Trials Registry; the Cochrane Library; hand searches of the references of retrieved literature; discussions with experts; and personal experience from the field. Results EED is established during infancy and is associated with poor sanitation, certain gut infections, and micronutrient deficiencies. Helicobacter pylori infection, small intestinal bacterial overgrowth (SIBO), abnormal gut microbiota, undernutrition, and toxins may all play a role. EED is usually asymptomatic, but it is important due to its association with stunting. Diagnosis is frequently by the dual sugar absorption test, although other biomarkers are emerging. EED may partly explain the reduced efficacy of oral vaccines in low- and middle-income countries and the increased risk of serious infection seen in children with undernutrition. Conclusions Despite its potentially significant impacts, it is currently unclear exactly what causes EED and how it can be treated or prevented. Ongoing trials involve nutritional supplements, water and sanitation interventions, and immunomodulators. Further research is needed to better understand this condition, which is of likely crucial importance for child health and development in low- and middle-income settings. PMID:25902619

This study had four purposes: (1) to investigate the relationship between performance in introductory biology or introductory chemistry lecture courses and their accompanying laboratory courses, (2) to investigate the relationship between performance in introductory biology or introductory chemistry lecture courses and a student's gender, (3) to investigate the relationship between performance in introductory biology or introductory chemistry lecture courses and a student's major, and (4) to investigate the relationship between performance in introductory biology or introductory chemistry lecture courses and a student's ACT scores. The sample consisted of 195 first--time freshmen who enrolled in and completed an introductory biology or an introductory chemistry lecture and laboratory courses during the fall semesters of 2007-2012. Of the 195 students, 61 were enrolled in introductory chemistry and 134 were enrolled in introductory biology courses. Logistic regression, via the Statistical Package for the Social Sciences (SPSS), was utilized to analyze several variables as they related to success in the lecture courses. Data were extracted from the university's student information system (BANNER), and analyses were conducted on biology and chemistry separately. The dependent variable for this study was a dichotomous variable for success and nonsuccess in introductory biology or introductory chemistry lecture course. The independent variables analyzed were student's gender, major, final grade in an accompanying biology or chemistry laboratory course, and ACT test scores (composite, mathematics, and science). Results indicate that concurrent enrollment in a biology laboratory course increased the likelihood of success by 15.64 times in the lecture course. Gender was found to not be a significant predictor of success for either introductory biology or introductory chemistry lecture courses. STEM majors were 9.6 times more likely to be successful than non-STEM majors in

Home enteral nutrition via jejunostomy requires considerable time for infusion to the patients. A new method using semisolid enteral formula dramatically reduces the time of infusion. This method makes use of pectin and liquid enteral formula. The authors applied this method in two patients with total gastrectomy being given enteral nutrition at home. There were no complications such as diarrhea or abdominal pain. This new method of home enteral nutrition could enhance the patients' quality of life (QOL) by reducing the time of infusion of enteral nutrition.

Given the paucity of published data regarding reaction rates in younger teenaged donors, we evaluated the reaction rates in all of our first time teenaged donors after New York Blood Center lowered the minimum permissible age for blood donations from 17 to 16 yr in 2005. The overall rates of vaso-vagal reactions in donors aged 16 to 19, and those resulting in syncope, occurring in 72,769 consecutive first time whole blood, 3,822 double red cell, and 777 platelet apheresis donations were calculated. They were correlated with age and compared to those found in donors aged 20-29. Separate rates were calculated by gender, age in yr, and donation type, and then compared to each other. The overall reaction rate among first time teenaged whole blood donors was 8.2% and was significantly greater than among plateletpheresis donors (4.0%; p <0.0002). The rate in female whole blood donors (10.0%) was significantly higher than in males (6.4%; p <0.0002). In male double red cell donors the overall reaction rate of 3.5% was significantly lower than that found in male whole blood donors (p <0.002). Among both male and female whole blood donors a significant correlation with decreasing donor age between 19 and 16 yr was found (r(2) = 0.981; p = 0.01) and (r(2) = 0.988; p = 0.006), respectively. We conclude that teenaged donors have increased reaction rates when compared to adults and the reaction rates increase with decreasing age. In addition, females have higher reaction rates than males. Finally, reaction rates associated with apheresis donations are significantly lower than those associated with whole blood donations.

Parenting stress has been shown to affect relationships between mothers and their infants. Single mothers may experience more parenting stress due to exposure to stressors that are unique to their environment. The purpose of this secondary analysis was to determine the differences between married and single first-time mothers on the Parenting Stress Index/Short Form (PSI/SF Abidin, 1995). A convenience sample of 22 single and 52 married first-time mothers were recruited from postpartum units in two large metropolitan hospitals in the southeastern United States. During hospitalization, participants completed a demographic sheet and at six weeks postpartum, were mailed the PSI/SF. T-tests were assessed for differences between mean scores. Study findings indicate significant differences between single and married first-time mothers on the Parental Distress subscale (t = -3.468, p = .001), the Difficult Child subscale (t = -2.032, p = .046), and Defensive Responding subscale (t = -3.720, p = .000), with single mothers consistently scoring higher than married mothers; however, there was not a significant statistical difference between mothers on the Parent-Child Dysfunctional Interaction subscale (t = -1.290, p = .201). Overall, single mothers scored higher on the Total Parenting Stress scores of the PSI/SF than married mothers (t = -2.858, p = .005), suggesting that single women experience more stress as a new mother than married new mothers. It is important to understand the specific stressors of new, single mothers and to develop nursing interventions that decrease parenting stress in single mothers.

Context No researchers, to our knowledge, have investigated the immediate postinjury-movement strategies associated with acute first-time lateral ankle sprain (LAS) as quantified by center of pressure (COP) and kinematic analyses during performance of the Star Excursion Balance Test (SEBT). Objective To analyze the kinematic and COP patterns of a group with acute first-time LAS and a noninjured control group during performance of the SEBT. Design Case-control study. Setting University biomechanics laboratory. Patients or Other Participants A total of 81 participants with acute first-time LAS (53 men, 28 women; age = 23.22 ± 4.93 years, height = 1.73 ± 0.09 m, mass = 75.72 ± 13.86 kg) and 19 noninjured controls (15 men, 4 women; age = 22.53 ± 1.68 years, height = 1.74 ± 0.08 m, mass = 71.55 ± 11.31 kg). Intervention Participants performed the anterior (ANT), posterolateral (PL), and posteromedial (PM) reach directions of the SEBT. Main Outcome Measure(s) We assessed 3-dimensional kinematics of the lower extremity joints and associated fractal dimension (FD) of the COP path during performance of the SEBT. Results The LAS group had decreased normalized reach distances in the ANT, PL, and PM directions when compared with the control group on their injured (ANT: 58.16% ± 6.86% versus 64.86% ± 5.99%; PL: 85.64% ± 10.62% versus 101.14% ± 8.39%; PM: 94.89% ± 9.26% versus 107.29 ± 6.02%) and noninjured (ANT: 60.98% ± 6.74% versus 64.76% ± 5.02%; PL: 88.95% ± 11.45% versus 102.36% ± 8.53%; PM: 97.13% ± 8.76% versus 106.62% ± 5.78%) limbs (P < .01). This observation was associated with altered temporal sagittal-plane kinematic profiles throughout each reach attempt and at the point of maximum reach (P < .05). This result was associated with a reduced FD of the COP path for each reach direction on the injured limb only (P < .05). Conclusions Acute first-time LAS was associated with bilateral deficits in postural control, as evidenced by the bilateral

It is the position of the American College of Clinical Pharmacy (ACCP) that formal postgraduate residency training, or equivalent experience, is required to enter direct patient care practice. Therefore, it is important to align professional degree educational outcomes with the knowledge, skills, and attitudes needed to enter residency training. This position statement addresses the outcomes necessary in the professional degree program curriculum to ensure the ability of pharmacy graduates to transition effectively into postgraduate year one residency training. Five key outcome areas are identified: communication, direct patient care, professionalism, research, and practice management. The position statement examines how performance in each of the five outcome areas should be addressed by professional degree programs. The ACCP believes that for the student to achieve the clinical proficiency necessary to enter residency training, the professional degree program should emphasize, assess, and provide adequate opportunities for students to practice: communication with patients, caregivers, and members of the health care team in direct patient care environments; provision of direct patient care in a wide variety of practice settings, especially those involving patient-centered, team-based care; professionalism under the supervision and guidance of faculty and preceptors who model and teach the traits of a health care professional; application of principles of research that engender an appreciation for the role of research and scholarship in one's professional development; and application of practice management, including documentation of direct patient care activities that affect drug-related outcomes.

The present study was designed to identify and characterize the major factors that influence entering science teacher candidates' preferences for different types of instructional activities, and to analyze what these factors suggest about teacher candidates' orientations towards science teaching. The study involved prospective teachers enrolled in the introductory science teaching course in an undergraduate science teacher preparation program. Our analysis was based on data collected using a teaching and learning beliefs questionnaire, together with structured interviews. Our results indicate that entering science teacher candidates have strong preferences for a few activity types. The most influential factors driving entering science teacher candidates' selections were the potential of the instructional activities to motivate students, be relevant to students' personal lives, result in transfer of skills to non-science situations, actively involve students in goal-directed learning, and implement curriculum that represents what students need to know. This set of influencing factors suggests that entering science teacher candidates' orientations towards teaching are likely driven by one or more of these three central teaching goals: (1) motivating students, (2) developing science process skills, and (3) engaging students in structured science activities. These goals, and the associated beliefs about students, teaching, and learning, can be expected to favor the development or enactment of three major orientations towards teaching in this population of future science teachers: "motivating students," "process," and "activity-driven."

Hepatitis viruses of oral-fecal origin are responsible for a high morbidity and mortality throughout the world, even if they never result in chronic hepatitis. Two viruses, the virus of hepatitis A (VHA) and of hepatitis E (VHE) are at present the cause of severe viral hepatitis of enteric origin. Water is the principle vector in the spread of these viruses. However, the epidemiological aspects vary according to the pathogenic agent. VHA is excreted in a highly concentrated form in the feces for a relatively short period of time. Since it resists in an exterior environment, the virus remains infectious for a long time. VHE is excreted for a short period of time and in low concentrations. The viral particles are fragile in vitro and their variability in the environment is little known. The possible reservoir role of certain animals has been envisaged. Epidemics arise especially in countries suffering from poor hygiene and massive water pollution. Hepatitis A should no longer be considered a benign disease of childhood. The progress made in hygiene and economic development in industrialized countries have made contacts with this virus scarce, rendering the populations more receptive to it and epidemics more widespread. When the sickness occurs later in life, infection is more often symptomatic and can be serious, resulting sometimes long-term indisposition. Hepatitis E has a vast distribution throughout the world and manifests itself either in epidemic or endemic-sporadic form in many poor countries. In developed countries, it comes about mostly as a result of imported pathology, even if there exists a "substratum" of infection in these areas. The main clinical aspects, such as we were able to study them in 39 cases of military men from Tchad, Guyana and Somalia, are comparable to those of hepatitis A. The reasons for the particular gravity of symptoms in pregnant women are unknown. These affections have no specific treatment. In the field of prevention, vaccination

Driving while impaired (DWI) is a frequently committed crime with enormous individual and social costs. The type of disposition and/or treatment appropriate for an individual offender is often determined, in part, by diagnostic criteria based on the American Psychiatric Association's Diagnostic and Statistics Manual. The DSM-5 significantly modified these criteria by eliminating legal problems as a criterion and dropping the categories of abuse and dependence. A brief substance abuse focused interview was conducted with 658 consecutive first-time DUI offenders who were arrested for driving under the influence of alcohol. Most were white, well-educated males. Contingency analyses were utilized to compare the current with the new diagnostic criteria based on algorithms for both diagnostic formulations. The major change observed when moving from DSM-IV-TR to DSM-5 criteria was that, approximately 54% of first-time DUI/DWI offenders would no longer meet diagnostic criteria based on the DSM-5. Of the nearly 17% who met dependence criteria, the majority were in the severe designation of the DSM-5.

The transition to parenthood is widely considered a period of increased vulnerability often accompanied by stress. Abidin conceived parenting stress as referring to specific difficulties in adjusting to the parenting role. Most studies of psychological distress arising from the demands of parenting have investigated the impact of stress on the development of dysfunctional parent–child relationships and on adult and child psychopathology. Studies have largely focused on mothers’ postnatal experience; less attention has been devoted to maternal prenatal characteristics associated with subsequent parental stress and studies of maternal prenatal predictors are few. Furthermore, no studies have examined that association exclusively with samples of first-time mothers. With an observational prospective study design with two time periods, the aim of this study was to investigate the role of mothers’ attachment style, maternal prenatal attachment to the fetus and dyadic adjustment during pregnancy (7th months of gestation) and their potential unique contribution to parenting stress 3 months after childbirth in a sample of nulliparous women. Results showed significant correlations between antenatal measures. Maternal attachment style (especially relationship anxiety) was negatively correlated with prenatal attachment and with dyadic adjustment; positive correlations resulted between prenatal attachment and dyadic adjustment. Each of the investigated variables was also good predictor of parenting stress 3 months after childbirth. Findings suggested how these dimensions could be considered as risk factors in the transition to motherhood and in the very beginning of the emergence of the caregiving system, especially with first-time mothers.

The purpose of this study is to evaluate the effectiveness of a single session intervention designed to reduce emotional distress in first-time mothers. We held a parenting class for first-time mothers who had given birth at a university hospital in Tokyo, Japan. The program of the class consists of lectures on infant care and group discussion, which is a common form of intervention in Japan. The effectiveness of intervention is assessed according to differences in emotional distress experienced by class participants and nonparticipants, and analyzed by the use of a propensity score method to avoid self-selection bias. In order to be more confident about our results, we employ several variations of this method. Results from statistical analysis show that although the effectiveness of the intervention was limited, it was able to alleviate subjects' loss of self-confidence as mothers. Because this outcome shows a good degree of consistency across methods, it can be considered robust. Moreover, it is roughly consistent with previous studies. Effectiveness can probably be increased by developing a program that improves upon the intervention.

For prevention purposes, it is important that police officers can estimate the risk for delinquency among juveniles who were involved in a criminal offense, but not in the role of a suspect. In the present study, the Youth Actuarial Risk Assessment Tool for First-Time Offending (Y-ARAT-FO) was developed based solely on police records with the aim to enable Dutch police officers to predict the risk for first-time offending. For the construction of this initial screening instrument, an Exhaustive Chi-squared Automatic Interaction Detector (Exhaustive CHAID) analysis was performed on a data set that was retrieved from the Dutch police system. The Y-ARAT-FO was developed on a sample of 1,368 juveniles and validated on a different sample of 886 juveniles showing moderate predictive accuracy in the validation sample (area under the receiver operating characteristic curve [AUC] = .728). The predictive accuracy of the Y-ARAT-FO was considered sufficient to justify its use as an initial screening instrument by the Dutch police.

Two studies examined the relationship between maternal attitudes and symptoms of depression and anxiety during pregnancy and the early postpartum period. In the first study, a measure of maternal attitudes, the Attitudes Toward Motherhood Scale (AToM), was developed and validated in a sample of first-time mothers. The AToM was found to have good internal reliability and convergent validity with cognitive biases and an existing measure of maternal attitudes. Exploratory and confirmatory factor analyses determined that the measure comprises three correlated factors: beliefs about others' judgments, beliefs about maternal responsibility, and maternal role idealization. In the second study, we used the AToM to assess the relationship between maternal attitudes and other psychological variables. The factor structure of the measure was confirmed. Maternal attitudes predicted symptoms of depression and anxiety, and these attitudes had incremental predictive validity over general cognitive biases and interpersonal risk factors. Overall, the results of these studies suggest that maternal attitudes are related to psychological distress among first-time mothers during the transition to parenthood and may provide a useful means of identifying women who may benefit from intervention during the perinatal period.

The study aim was to compare sleep, sleepiness, fatigue, and neurobehavioral performance among first-time mothers and fathers during their early postpartum period. Participants were 21 first-time postpartum mother-father dyads (N=42) and seven childless control dyads (N=14). Within their natural environment, participants completed one week of wrist actigraphy monitoring, along with multi-day self-administered sleepiness, fatigue, and neurobehavioral performance measures. The assessment week was followed by an objective laboratory based test of sleepiness. Mothers obtained more sleep compared to fathers, but mothers’ sleep was more disturbed by awakenings. Fathers had greater objectively measured sleepiness than mothers. Mothers and fathers did not differ on subjectively measured sleep quality, sleepiness, or fatigue; however, mothers had worse neurobehavioral performance than fathers. Compared to control dyads, postpartum parents experienced greater sleep disturbance, sleepiness, and sleepiness associated impairments. Study results inform social policy, postpartum sleep interventions, and research on postpartum family systems and mechanisms that propagate sleepiness. PMID:22553114

Water quality through the presence of pathogenic enteric microorganisms may affect human health. Coliform bacteria, Escherichia coli and coliphages are normally used as indicators of water quality. However, the presence of above-mentioned indicators do not always suggest the presence of human enteric viruses. It is important to study human enteric viruses in water. Human enteric viruses can tolerate fluctuating environmental conditions and survive in the environment for long periods of time becoming causal agents of diarrhoeal diseases. Therefore, the potential of human pathogenic viruses as significant indicators of water quality is emerging. Human Adenoviruses and other viruses have been proposed as suitable indices for the effective identification of such organisms of human origin contaminating water systems. This article reports on the recent developments in the management of water quality specifically focusing on human enteric viruses as indicators.

Objectives: The aims of this study were to (1) develop a series of short interactive videos (or reusable learning objects [RLOs]) covering a broad range of practical and psychosocial issues relevant to the auditory rehabilitation for first-time hearing aid users; (2) establish the accessibility, take-up, acceptability and adherence of the RLOs; and (3) assess the benefits and cost-effectiveness of the RLOs. Design: The study was a single-center, prospective, randomized controlled trial with two arms. The intervention group (RLO+, n = 103) received the RLOs plus standard clinical service including hearing aid(s) and counseling, and the waitlist control group (RLO−, n = 100) received standard clinical service only. The effectiveness of the RLOs was assessed 6-weeks posthearing aid fitting. Seven RLOs (total duration 1 hr) were developed using a participatory, community of practice approach involving hearing aid users and audiologists. RLOs included video clips, illustrations, animations, photos, sounds and testimonials, and all were subtitled. RLOs were delivered through DVD for TV (50.6%) and PC (15.2%), or via the internet (32.9%). Results: RLO take-up was 78%. Adherence overall was at least 67%, and 97% in those who attended the 6-week follow-up. Half the participants watched the RLOs two or more times, suggesting self-management of their hearing loss, hearing aids, and communication. The RLOs were rated as highly useful and the majority of participants agreed the RLOs were enjoyable, improved their confidence and were preferable to written information. Postfitting, there was no significant between-group difference in the primary outcome measure, overall hearing aid use. However, there was significantly greater hearing aid use in the RLO+ group for suboptimal users. Furthermore, the RLO+ group had significantly better knowledge of practical and psychosocial issues, and significantly better practical hearing aid skills than the RLO− group. Conclusions: The RLOs

Objectives: Our objective was to determine the impact that a patient's geographic status has on the efficacy of first-time methadone maintenance therapy (MMT) retention. Methods: We conducted an observational cohort study using administrative health care databases for patients who commenced methadone therapy between 2003 and 2012. Patients were stratified on the basis of their location of residence into 1 of 4 groups—Southern Urban, Southern Rural, Northern Urban, or Northern Rural. The primary outcome was continuous retention in treatment, defined as 1 year of uninterrupted therapy on the basis of prescription refill data. Mortality was measured as a secondary outcome. Results: We identified 17,211 patients initiating first-time MMT during this 10-year period. Nearly half of patients initiating therapy in northern regions completed 1 year of treatment (48.9%; N = 258 and 47.0%; N = 761 in Northern Rural and Urban regions, respectively), whereas lower rates of 40.6% (N = 410) and 39.3% (N = 5,518) occurred in Southern Rural and Urban regions, respectively. Patients residing in Northern Rural and Northern Urban regions were 31% (adjusted odds ratio = 1.31; 95% confidence interval [CI], 1.09%–1.58%] and 14% (adjusted odds ratio = 1.14; 95% CI, 1.02%–1.27%] more likely to be retained in treatment compared with those residing in Southern Urban regions. There was no significant difference in treatment retention between those residing in Southern Rural and Southern Urban regions. A mortality rate of 3% was observed within 1 year of patients initiating treatment, with patients in the Southern Rural region having the highest rate (4.85%). Conclusions: Our study identified regional differences in retention rates and mortality of first-time MMT. These findings may relate to geographic isolation and limited methadone program availability experienced in northern regions. We interpret the data to suggest that patients who have reduced access to

Accepted 16 April 1997 Nutritional insult after bone marrow transplantation (BMT) is complex and its nutritional management challenging. Enteral nutrition is cheaper and easier to provide than parenteral nutrition, but its tolerance and effectiveness in reversing nutritional depletion after BMT is poorly defined. Nutritional status, wellbeing, and nutritional biochemistry were prospectively assessed in 21 children (mean age 7.5 years; 14 boys) who received nasogastric feeding after BMT (mean duration 17 days) and in eight children (mean age 8 years, four boys) who refused enteral nutrition and who received dietetic advice only. Enteral nutrition was stopped prematurely in eight patients. Greater changes in weight and mid upper arm circumference were observed in the enteral nutrition group, while positive correlations were found between the duration of feeds and increase in weight and in mid upper arm circumference. Vomiting and diarrhoea had a similar incidence in the two groups, while fever and positive blood cultures occurred more frequently in the dietetic advice group. Diarrhoea occurring during enteral nutrition was not associated with fat malabsorption, while carbohydrate malabsorption was associated with rotavirus infection only. Enteral feeding did not, however, affect bone marrow recovery, hospital stay, general wellbeing, or serum albumin concentrations. Hypomagnesaemia, hypophosphataemia, zinc and selenium deficiency were common in both groups. In conclusion, enteral nutrition, when tolerated, is effective in limiting nutritional insult after BMT. With existing regimens nutritional biochemistry should be closely monitored in order to provide supplements when required. PMID:9301351

Using cross-sectional data and structural equation modeling, we evaluated whether coping self-efficacy to abstain from drinking in various situations accounted for the relationship between internalizing (depression, anxiety) and externalizing (aggression, low socialization) dimensions with problematic alcohol use in 292 first-time DWI offenders. Results indicated that an internalizing dimension indirectly predicted problematic alcohol use through coping self-efficacy in negative situations only, whereas an externalizing dimension indirectly predicted problematic alcohol use through coping self-efficacy in positive situations only. These findings support two potential pathways to problematic drinking behavior among DWI offenders and suggest that internalizing and externalizing dimensions may differentially predict high risk drinking situations due to one's inability to abstain in specific situations.

AZ-Tek's AZW-LA-II low solar absorptance white paint was previously flown as a flight experiment, and is being flown as a calorimeter. However it has never been flown as a thermal coating of radiators on an operational spacecraft before. This paint has the lowest solar absorptance among all white paints, and a very small degradation. Its cost is many times more expensive than white paints that have a higher solar absorptance. To meet the thermal requirements of the Swift Burst Alert Telescope (BAT) Detector Array and X-Ray Telescope (XRT) focal plane camera assembly (FPCA) charged coupled device (CCD), AZW-LA-II is used as the thermal coating for the BAT and XRT radiators. This paper presents the lessons learned from flying this low solar absorptance white paint as a thermal coating of radiators on an operational spacecraft for the first time.

Study Objective: To describe sleep duration and quality in the first month postpartum and compare the sleep of women who exclusively breastfed at night to those who used formula. Methods: We conducted a longitudinal study in a predominantly low-income and ethnically diverse sample of 120 first-time mothers. Both objective and subjective measures of sleep were obtained using actigraphy, diary, and self-report data. Measures were collected in the last month of pregnancy and at one month postpartum. Infant feeding diaries were used to group mothers by nighttime breastfeeding behavior. Results: Mothers who used at least some formula at night (n = 54) and those who breastfed exclusively (n = 66) had similar sleep patterns in late pregnancy. However, there was a significant group difference in nocturnal sleep at one month postpartum as measured by actigraphy. Total nighttime sleep was 386 ± 66 minutes for the exclusive breastfeeding group and 356 ± 67 minutes for the formula group. The groups did not differ with respect to daytime sleep, wake after sleep onset (sleep fragmentation), or subjective sleep disturbance at one month postpartum. Conclusion: Women who breastfed exclusively averaged 30 minutes more nocturnal sleep than women who used formula at night, but measures of sleep fragmentation did not differ. New mothers should be encouraged to breastfeed exclusively since breastfeeding may promote sleep during postpartum recovery. Further research is needed to better understand how infant feeding method affects maternal sleep duration and fragmentation. Citation: Doan T; Gay CL; Kennedy HP; Newman J; Lee KA. Nighttime breastfeeding behavior is associated with more nocturnal sleep among first-time mothers at one month postpartum. J Clin Sleep Med 2014;10(3):313-319. PMID:24634630

We report the successful piglet production from cryopreserved oocytes for the first time by using a simple, high capacity vitrification protocol for preservation and a defined system for in vitro embryo production. Immature cumulus-oocyte complexes (COCs) from prepubertal gilts were vitrified in microdrops and stored in liquid nitrogen. After warming, COCs were subjected to in vitro maturation (IVM), fertilization (IVF), and subsequent culture (IVC). Adjusting warmplate temperature to 42 °C during warming prevented temperature drops in a medium below 34.0 °C and significantly increased the percentage of oocyte survival and thus blastocyst yields obtained from total vitrified oocytes compared with that of warming at 38 °C (87.1% vs 66.9% and 4.4% vs 2.7%, respectively). Nuclear maturation and fertilization of oocytes were not affected by vitrification and warming temperature. Blastocyst development on day 7 (day 0 = IVF) of the surviving oocytes after warming at 38 °C and 42 °C was not different but lower (P<0.05) than those of non-vitrified control oocytes (4.6%, 5.2% and 17.9%, respectively). However, blastocyst cell numbers in the control and vitrified groups were similar irrespective of warming temperature. Omitting porcine follicular fluid (pFF) from IVM medium (POM) did not affect maturation, fertilization and embryo development of vitrified-warmed oocytes. Transfer of blastocysts obtained on day 5 from vitrified oocytes matured either with or without pFF into 4 recipients (2 for each group) resulted in 4 pregnancies and the delivery of a total of 18 piglets. In conclusion, optimization of warming temperature was a key factor for achieving high survival rates, and surviving oocytes could be utilized in vitro using defined media. Using these modifications, live piglets could be obtained from cryopreserved oocytes for the first time.

Frequent supraventricular extrasystoles (SVEs) are associated with the subsequent first-time appearance of atrial fibrillation (AF) and ischemic stroke. The aim of this study was to investigate the combined role of SVEs and an AF-related risk score for ischemic stroke, the CHADS2 score, on the occurrence of new AF in patients in sinus rhythm. The Shinken Database 2004-2010 lists 3,263 patients who underwent 24-hour Holter monitoring. A total of 2,589 patients were analyzed, after excluding 674 patients previously diagnosed with AF. Frequent SVEs were defined as ≥102 beats/day (the top quartile) and the presence of a clinical background for a CHADS2 score ≥2 points as a high CHADS2 score. During the mean follow-up period of 571.4 ± 606.4 days, new AF occurred in 38 patients (9.4 per 1,000 patient-years). The incidence of new AF was 2.7 and 37.7 per 1,000 patient-years for patients with nonfrequent SVEs (<102 beats/day) and low CHADS2 scores and those with frequent SVEs and high CHADS2 scores, respectively. Multivariate Cox regression analysis showed that the hazard ratio for frequent SVEs and a high CHADS2 score compared with nonfrequent SVEs and a low CHADS2 score was 9.49 (95% confidence interval 3.20 to 28.15, p <0.001), even after adjustment for gender, age, medications, and echocardiographic parameters. In conclusion, frequent SVEs and a high CHADS2 score independently and synergistically predict the first-time appearance of AF in patients in sinus rhythm, indicating an approximately 10-fold higher risk. Patients meeting these criteria should have more aggressive early intervention for preventing AF.

In a prospective study of first-time low back pain among New York City fire fighters, a total of 115 cases and 109 randomly selected controls were interviewed by telephone between December 1988 and July 1989 to examine the role of recent work activities in the onset of first-time low back pain. After adjusting for known risk factors and off-duty activities, statistically significant high-risk work activities included operating a charged hose inside a building (odds ratio (OR) = 3.26), climbing ladders (OR = 3.18), breaking windows (OR = 4.45), cutting structures (OR = 6.47), looking for hidden fires (OR = 4.32), and lifting objects > or = 18 kg (OR = 3.07). Low-risk activities included connecting hydrants to pumpers (OR = 0.36), pulling booster hose (OR = 0.19), and participating in drills (OR = 0.09) or physical training (OR = 0.16). When further adjusted for exposure to smoke (OR = 13.59), a surrogate for severity of alarms, the ORs associated with high-risk activities were no longer significant. This, however, does not diminish the role of activities in the onset of low back pain. Instead, it suggests an inseparable role for activities and environmental hazards. To examine this, the risk of low back pain was measured within five work zones sequential in time relative to location and distance from a structural fire. The risk gradually increased as the fire fighter moved away from the firehouse (OR = 0.10) and closer to the site of fire (OR = 3.91).

It has become increasingly evident over the last years that Parkinson's disease is a multicentric neurodegenerative disease that affects several neuronal structures outside the substantia nigra, among which is the enteric nervous system. The aims of the present article are to discuss the role of the enteric nervous system lesions in pathology spreading (Braak's hypothesis) and in the gastrointestinal dysfunction encountered in Parkinson's disease. Owing to its accessibility to biopsies, we further discuss the use of the enteric nervous system as an original source of biomarker in Parkinson's disease.

Radiation enteritis is one of the most feared complications after abdominal and pelvic radiation therapy. The incidence varies from 0.5 to 5%. It is not rare that the slowly progressing condition will be fatal. During a period of 13 years 24 patients were operated due to the complication of radiation enteritis. Despite different types of surgery repeated operation was required in 25% of cases and finally 4 patients died. Analyzing these cases predisposing factors and different therapeutic options of this condition are discussed. Treatment options of radiation induced enteritis are limited; however, targeted therapy significantly improves the outcome. Cooperation between oncologist, gastroenterologist and surgeon is required to establish adequate therapeutic plan.

Introduction. In patients with acute pancreatitis (AP), nutritional support is required if normal food cannot be tolerated within several days. Enteral nutrition is preferred over parenteral nutrition. We reviewed the literature about enteral nutrition in AP. Methods. A MEDLINE search of the English language literature between 1999–2009. Results. Nasogastric tube feeding appears to be safe and well tolerated in the majority of patients with severe AP, rendering the concept of pancreatic rest less probable. Enteral nutrition has a beneficial influence on the outcome of AP and should probably be initiated as early as possible (within 48 hours). Supplementation of enteral formulas with glutamine or prebiotics and probiotics cannot routinely be recommended. Conclusions. Nutrition therapy in patients with AP emerged from supportive adjunctive therapy to a proactive primary intervention. Large multicentre studies are needed to confirm the safety and effectiveness of nasogastric feeding and to investigate the role of early nutrition support. PMID:20811543

Malnutrition in hospitalised patients has a significant and disadvantageous impact on treatment outcome. If possible, enteral nutrition with an energy/protein-balanced nutrient should be preferred depending on the patient's condition, type of illness and risk factors. The aim of the nutrition therapy is to increase the efficacy of treatment and shorten the length of hospital stay in order to ensure rapid rehabilitation. In the present review the authors summarize the most important clinical and practical aspects of enteral nutrition therapy.

Background Maternal health services have a potentially critical role in the improvement of reproductive health. In order to get a better understanding of adolescent mothers'needs we compared health seeking practices of first time adolescent and adult mothers during pregnancy and early motherhood in Wakiso district, Uganda. Methods This was a cross-sectional study conducted between May and August, 2007 in Wakiso district. A total of 762 women (442 adolescents and 320 adult) were interviewed using a structured questionnaire. We calculated odds ratios with their 95% CI for antenatal and postnatal health care seeking, stigmatisation and violence experienced from parents comparing adolescents to adult first time mothers. STATA V.8 was used for data analysis. Results Adolescent mothers were significantly more disadvantaged in terms of health care seeking for reproductive health services and faced more challenges during pregnancy and early motherhood compared to adult mothers. Adolescent mothers were more likely to have dropped out of school due to pregnancy (OR = 3.61, 95% CI: 2.40–5.44), less likely to earn a salary (OR = 0.43, 95%CI: 0.24–0.76), and more likely to attend antenatal care visits less than four times compared to adult mothers (OR = 1.52, 95%CI: 1.12–2.07). Adolescents were also more likely to experience violence from parents (OR = 2.07, 95%CI: 1.39–3.08) and to be stigmatized by the community (CI = 1.58, 95%CI: 1.09–2.59). In early motherhood, adolescent mothers were less likely to seek for second and third vaccine doses for their infants [Polio2 (OR = 0.73, 95% CI: 0.55–0.98), Polio3 (OR = 0.70: 95% CI: 0.51–0.95), DPT2 (OR = 0.71, 95% CI: 0.53–0.96), DPT3 (OR = 0.68, 95% CI: 0.50–0.92)] compared to adult mothers. These results are compelling and call for urgent adolescent focused interventions. Conclusion Adolescents showed poorer health care seeking behaviour for themselves and their children, and experienced increased community

This study examines the impact of the Mississippi Alcohol Safety Education Program (MASEP), a court-mandated intervention program, on 3-year recidivism rates among first-time DUI offenders (i.e. those convicted of a first offense for driving under the influence of alcohol or another drug). It also examines whether a new version of the curriculum that incorporates activities to enhance motivation for change further ameliorates recidivism. Cox proportional hazard regression models are used to compare recidivism rates among DUI offenders who completed MASEP with those who did not complete or who failed to enroll in the program. Recidivism rates were also compared for MASEP participants across time periods during which curriculum revisions were introduced. The hazard of recidivism was lower for individuals who completed the program than for individuals who did not complete or did not enroll in the program. Recidivism rates were further reduced following the introduction of curriculum revisions. Attendance of court-mandated remedial intervention programs lower subsequent DUI arrests and program content is associated with lower rates.

Psychological distress, defined as depression, anxiety, and insomnia in this study, can occur following the birth of a baby as new mothers, in addition to marked physiological changes, are faced with adapting to new roles and responsibilities. We investigated the cooccurrence of stress, depression, anxiety, and insomnia in mothers during the postpartum period; tested the feasibility of study methods and procedures for use in this population; and identified new mothers interest in using cranial electrotherapy stimulation (CES) as an intervention for reducing psychological distress. We recruited healthy, low-risk, English speaking first-time mothers, ages 18–32 years, with healthy babies (N = 33), within 12 months of an uncomplicated birth. Participants completed the PSS, HAM-D14, HAM-A17, and PSQI19. No problems were encountered with study procedures. Mothers reported a high interest (4.9) in the potential use of CES to treat or prevent the occurrence of psychological distress. All participants (N = 33) reported moderate levels of depression and anxiety, while 75.8% (n = 25) reported insomnia. PSS scores were within the norms for healthy women. Further research is recommended to investigate if our findings can be replicated or if different patterns of associations emerge. Implications for clinical practice are addressed. PMID:28191350

Although the pulsed plasma thruster (PPT) was first utilized on a space mission in 1964, after more than four decades, it is still a space-rated technology which has performed various propulsion tasks, from station-keeping to three-axis attitude control for a variety of former missions. With respect to the rapid growth in the small satellite community and the growing interest for smaller satellites in recent years, the PPT is one of the promising electric propulsion devices for small satellites (e.g., CubeSats) due to the following advantages: simplicity, lightweight, robustness, low power consumption, low production cost and small dimensions. Therefore, a laboratory benchmark rectangular breech-fed pulsed plasma thruster using a self-inductor as a coupling element was designed, developed and successfully tested in a bell-type vacuum chamber at 10-4 Pa for the first time in west Asia (Iran). The PPT has been tested using a 35 μF, 2.5 kV oil-filled capacitor, producing an impulse bit varying from 300 μN-s to 1.3 mN-s at a maximum specific impulse of 1100 s. As a result a research program in Iran was initiated for working on PPTs and the miniaturization of PPTs while increasing the performance parameters. The present paper briefly reviews the PPT design and development.

Reported is the prevalence of hepatitis C virus (HCV) in Namibia as determined using a third-generation enzyme-linked immunosorbent assay (ELISA) on samples of blood collected from all asymptomatic, first-time blood donors between 1 February and 31 July 1997 (n = 1941). The HCV seroprevalence was 0.9% (95% confidence interval (CI): 0.5-1.5%) and no associations were detected between a positive HCV serostatus and the person's sex, region of residence, or previous hepatitis B exposure or hepatitis B carrier status, as determined by hepatitis B surface antigen (HBsAg). The only significant association in a logistic regression model was an increase in HCV positivity with increasing age (P = 0.04). Viral RNA was amplified from 2 out of 18 (11.1%) specimens that were ELISA positive. Genotyping of these specimens, by restriction fragment length polymorphism (RFLP), showed the presence of genotypes 5 and 1a. The positive predictive value of using HBsAg positivity as a surrogate screening marker for HCV in Namibian blood donors was poor (1.6%), with low sensitivity (16.7%) and specificity (89.3%), and detecting only 3 out of 18 serologically HCV-positive specimens. The results of this first study of the prevalence and epidemiology of HCV infection in Namibia suggest that donor blood should be screened for HCV by ELISA in order to prevent the transmission of hepatitis C virus.

Research on men who have sex with men suggests that condomless anal intercourse occurs more frequently in established sexual relationships. While comparable data regarding male-for-male escorting is unavailable, research implies that many clients seek emotional as well as physical connections with the men they hire. In 2012, 495 male clients, recruited via daddysreviews.com completed an online survey about their last hiring experience. Most participants were from the USA (85.7%), the UK and Canada (3.2% each). In total, 75% of encounters involved an escort hired for the first time; 25% were with a previously hired escort ('repeat encounter'). The client's age, lifetime number of escorts hired and number hired in the past year were positively associated with the last encounter being a repeat encounter. Cuddling, sharing a meal, drinking alcohol, taking a walk, watching a show and shopping were also positively associated with repeat encounters. Conversely, none of the sexual behaviours were significantly associated with repeat encounters. Repeat encounters were significantly more likely to include non-sexual behaviours alongside sexual activities, but no more likely to involve condomless anal intercourse. Moreover, clients' knowledge of escorts' HIV status was not significantly associated with engaging in condomless anal intercourse with repeat encounters.

This study examined the relationships between social and demographic characteristics (ie, gender, race, year in school, desired residency choice, and socioeconomic background), motivations for entering the profession of podiatric medicine (extrinsic and intrinsic rewards), and negative attitudes toward treating elderly patients. The study used ordinary least squares multiple regression models to analyze data from a random, national sample of 448 podiatric medical students. In particular, the ordinary least squares models were developed to determine the independent effect of intrinsic and extrinsic rewards on negative attitudes toward treating elderly patients. Consistent with the study hypotheses, after adjusting for social and demographic characteristics, the study found extrinsic rewards to have strong positive relationships with negative attitudes toward treating elderly patients, and intrinsic rewards to have strong negative relationships with negative attitudes toward treating elderly patients. The authors discussed the implications of the findings for podiatric physicians and educators training podiatric medical students.

Hypophosphatemia is uncommon in cats, but it has been reported in association with diabetes mellitus and hepatic lipidosis, where it can cause hemolysis, rhabdomyopathy, depression, seizures, and coma. The purpose of this article is to describe 9 cats that developed low serum phosphorus concentrations (< 2.5 mg/dL) subsequent to enteral alimentation. Serum biochemical analyses from more than 6,000 cats were reviewed. The medical records of all cats with hypophosphatemia were examined for history of enteral alimentation; diabetic cats were excluded from the study. Nine cats, ranging in age from 3 to 17 years, were identified. All cats had normal serum phosphorus concentrations before tube feeding began. Onset of hypophosphatemia occurred 12 to 72 hours after initiation of enteral alimentation, and the nadir for phosphorus concentrations ranged from 0.4 to 2.4 mg/dL. Hemolysis occurred in 6 of the 9 cats. Hypophosphatemia secondary to enteral alimentation is an uncommon clinical finding in cats. Cats with high alanine aminotransferase activity, hyperbilirubinemia, and weight loss should be closely monitored for hypophosphatemia during the first 72 hours of enteral alimentation.

The American Society on Addiction Medicine's Patient Placement criteria are commonly used in adolescent treatment. However, the use of these criteria and how they affect the course of treatment and interact with adolescent change has not been examined. Twelve-month treatment patterns were examined for 176 adolescents who entered their first ever episode in a treatment system using these criteria. Forty-one percent of the adolescents received additional treatment after their initial outpatient episode with over 30 unique treatment sequences (i.e., various combinations of outpatient, intensive outpatient, and residential treatment). Significant differences in treatment patterns were found between the change trajectory groups. For example, adolescents who participated in only one outpatient treatment episode were more likely to be in the low alcohol and drug use (AOD) group and less likely to have high rates of time in a controlled environment or to report moderate AOD use. Over one-third of the adolescents participated in additional treatment and almost one-quarter of those who only participated in outpatient treatment had problematic use. These findings suggest the need for clinical monitoring protocols that can be used to identify adolescents needing additional treatment or recovery services.
Small carbon chain molecules play an important role in the formation of larger, complex molecules as well as in the destruction process of interstellar grains. Linear C3 was found in dense star forming regions and in shells of late type carbon stars. In the course of recent SOFIA cycle 4 observations we made a first time detection of the 13C-isotopologue 13CCC in space. Asymmetrically substituted 13CCC transitions were detected based on recent unpublished laboratory data. Following this detection we propose to look for the yet undetected C13CC isotopologue and to observe higher-J Q-transitions for both isotopologues. The measurements aim to determine the 13CCC/C13CC ratio which equals 2 for random 13C-incorporation during the C3 formation process. A non-random, chemically driven 13CCC/C13CC ratio will shed light on possible routes to C3-formation. Furthermore high level J-transitions are sensitive to the prevailing excitation conditions. Below 50K symmetrically substituted C13CC can only be cooled by collisions with the ambient gas, whereas asymmetrically substituted 13CCC is cooled by collisions AND radiation thanks to a small permanent dipole moment. Thus 13CCC/C13CC-intensity ratios of the Q(8) line will give insights into excitation mechanism and temperatures of C3. For the new measurements we choose SgrB2(M) as source in order to compare line strengths of C3 and its 13C-isotopologues at exactly the same conditions than we had in our previous CCC observations.

To determine whether computed tomography perfusion imaging (CTPI)-derived parameters are associated with vascular cognitive impairment (VCI) in patients with transient ischemic attack (TIA). Patients with first-time anterior circulation TIA (diagnosed within 24 h of onset) and normal cognition, treated between August 2009 and August 2014 at the Department of Neurology of Chengdu Military General Hospital, China, were analyzed retrospectively. Patients underwent whole-brain CTPI within 1 week of TIA to detect cerebral blood volume (CBV), cerebral blood flow (CBF), mean transit time (MTT) and time to peak (TTP) in the ischemic region. Based on cognitive function assessment 4 weeks after TIA, using the Montreal cognitive assessment (MoCA) and mini mental state examination, the patients were divided into control and VCI groups. CTPI parameters and other clinical data were compared between groups, and Spearman's correlation analysis used to identify associations between cognitive scores and CTPI parameters in the VCI group. 50 patients (25 per group; aged 55-72 years) were included. Patient age, gender, smoking status, alcohol consumption, educational level, time from TIA onset to admission, time from TIA onset to CTPI, and prevalence of hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation and hyperhomocysteinemia did not differ between groups. Both groups showed TTP and MTT prolongation, CBF reduction, but no change in CBV in the ischemic region; these changes were significantly larger in the VCI group (P < 0.05). MTT correlated negatively with MoCA score (r = -0.51, P = 0.009). CTPI could facilitate early diagnosis of VCI in patients with anterior circulation TIA.

While psychiatric disorders are common among juvenile delinquents, many mental health problems go undetected, increasing the likelihood for persistent difficulties. This is the first known study to examine mental health referral rates and recidivism in the juvenile justice system. In addition to the study, we review juvenile justice mental health screening to improve detection and treatment. Juvenile criminal records in conjunction with behavioral health screenings were analyzed to determine differences in referrals and recidivism among first time offenders. Recidivism rates were significantly lower (p = 0.04) and time to recidivism was significantly longer (p = 0.03) for those referred specifically for mental health services than for those without any referrals, even after adjusting for offense severity. While black youths had a significantly higher recidivism rate (p = 0.02) and a shorter time to recidivism (p = 0.009) than white youths, there was no significant difference between races when referred specifically for mental health services. Among the groups studied, black youths had the most profound positive effect from mental health referrals (p < 0.0001). This study indicates the importance of detecting mental health problems among juvenile delinquents, especially for black offenders. The apparent protective effect of mental health interventions necessitates screening that better identifies underlying psychosocial factors rather than strict reliance upon diagnostic criteria and self-report. Broader or even universal mental health referrals for juvenile offenders could reduce future legal system involvement and costs to society. We review potential reasons that mental health problems go undetected and provide recommendations.

Background Little is known about the rates of loss (depuration) of polybrominated diphenyl ethers (PBDEs) and polychlorinated biphenyls (PCBs) from mothers during lactation. Depuration rates affect infant exposure to chemicals during breast-feeding, and fetal and lactational transfers during subsequent pregnancies. Objective Our objective in this study was to estimate depuration rates of PBDEs and PCBs using serial samples of breast milk. Method Nine first-time mothers (primiparae) each collected samples at 4, 6, 8, 12, 16, 20, and 24 weeks after birth. Nine additional primiparae each collected two samples at varying time intervals (18 to > 85 weeks after birth). Analytical precision was assessed to evaluate the accuracy of measured monthly percentage declines in PBDEs and PCBs. Results The four major PBDE congeners decreased 2 or 3% ± 1% per month over the 6-month period. These decreases were consistent over a 50-fold range (21–1,330 ng/g lipid weight) of initial PBDE concentrations in breast milk. The change in PCB-153 ranged from + 0.3% to –0.6% per month, with heterogeneous slopes and greater intraindividual variability. PBDE and PCB concentrations declined 1% per month over longer periods (up to 136 weeks). Conclusions Our data indicate that PBDEs and PCBs are not substantially (4–18%) reduced in primiparae after 6 months of breast-feeding. Consequently, the fetal and lactational exposures for a second child may not be markedly lower than those for the first. Participants were volunteers from a larger study population (n = 82), and were typical in their PBDE/PCB levels and in many demographic and lifestyle factors. These similarities suggest that our results may have broader applicability. PMID:17805415

Decision making in health care has evolved substantially over the last century. Up until the late 1970s, medical decision making was predominantly intuitive and anecdotal. It was based on trial and error and involved high levels of problem solving. The 1980s gave way to empirical medicine, which was evidence based probabilistic, and involved pattern recognition and less problem solving. Although this represented a major advance in the quality of medical decision making, limitations existed. The advantages of the gold standard of the randomized controlled clinical trial (RCT) are well-known and this technique is irreplaceable in its ability to answer critical clinical questions. However, the RCT does have drawbacks. RCTs are expensive and can only capture a snapshot in time. As treatments change and new technologies emerge, new expensive clinical trials must be undertaken to reevaluate them. Furthermore, in order to best evaluate a single intervention, other factors must be controlled. In addition, the study population may not match that of another organization or provider. Although evidence-based medicine has provided powerful data for clinicians, effectively and efficiently tailoring it to the individual has not yet evolved. We are now in a period of transition from this evidence-based era to one dominated by the personalization and customization of care. It will be fueled by policy decisions to shift financial responsibility to the patient, creating a powerful and sophisticated consumer, unlike any patient we have known before. The challenge will be to apply medical evidence and personal preferences to medical decisions and deliver it efficiently in the increasingly busy clinical setting. In this article, we provide a robust review of the concepts of customized care and some of techniques to deliver it. We will illustrate this through a personalized decision model for the treatment decision after a first-time anterior shoulder dislocation.

The bioavailability and gastrointestinal site of release of enteric coated aspirin tablets ("Rhusal", G.P. Laboratories) were investigated following dosage with single tablets. A delay of one to more than eight hours was observed between dosage and the appearance of salicylate in plasma or saliva. This delay was decreased by pretreatment with metoclopramide. No aspirin or salicylate was detected in gastric aspirates. The mean urinary recovery of salicylate was equivalent to 92% of the administered dose. All these tests were consistent with the designed function of the enteric coating. The time course of concentrations of salicylate in saliva rather than in plasma was confirmed as a useful technique for the evaluation of different formulations of aspirin. The acceleration of gastric emptying by metoclopramide is a useful technique for the evaluation of enteric coated tablets.
Appropriate nutritional support is crucial in the therapeutic approach of multiple conditions, which justifies the frequent and increasing use of specific access routes for enteral and parenteral nutrition. This article reviews the relevant literature concerning indications, procedures, effectiveness and complications of enteral access routes in children. The decision between gastric and postpyloric access, and between nasogastric tube and gastrostomy is thoroughly discussed. Percutaneous endoscopic gastrostomy is the most commonly used technique when a long-term gastric access is required, given its efficacy and safety although the associated morbidity is not negligible;laparoscopic gastrostomy emerges as a potentially advantageous alternative.

The gastrointestinal system of horses is affected by a large variety of inflammatory infectious and noninfectious conditions. The most prevalent form of gastritis is associated with ulceration of the pars esophagea. Although the diagnostic techniques for alimentary diseases of horses have improved significantly over the past few years, difficulties still exist in establishing the causes of a significant number of enteric diseases in this species. This problem is compounded by several agents of enteric disease also being found in the intestine of clinically normal horses, which questions the validity of the mere detection of these agents in the intestine.
Our previous research into the dynamic viral community in the turkey gastrointestinal tract revealed a number of novel enteric viruses. Of particular note in this previous metagenomic investigation was the observation of a number of novel avian enteric picornaviruses, in addition to numerous other ...

Following intense rainfalls, during spring 2013 a first-time sliding failure developed over a gentle cultivated slope in Northern Apennines. The slope is made of weakly cemented layered sandstones and subordinate siltstones and mudstones of Eocene age. The morphology is fairly regular with an average angle of 15° that increases up to 25° in the lower part of the slope where the pelitic fraction is no longer present in the bedrock succession. Bedding generally dips into the slope though the presence of faults locally complicate the setting. The sliding interested the upper, more gentle part of the slope with a maximum depth of 10 to 15 meters. Morphological evidences indicate a rotational component of movement and rocks outcropping along the scarp show a moderate degree of weathering. The main landslide body maintained its coherence and only a minor part of the toe mobilized as a fast-moving flow. No building nor infrastructure was affected by the movement but a railway viaduct is present in the lower part of the slope. Following the 2013 failure, movements and pore pressures were monitored in the landslide deposit to control the evolution of the phenomena. During the following winter, the abundant precipitation caused a reactivation of the movement that led to a much larger fast-moving flow. In this work, we document the sequence of events that has interested the slope during the years 2013-2014. Subsequent ground-based and aerial topographic surveys allow to estimate the volumes involved in the different phases of movement. Field evidences and investigations are used to interpret the geotechnical model of the slope and constrain the range of resistances mobilized at failure. The deformations preceding the 2014 reactivation are analyzed together with post-failure landslide deceleration. It is shown that displacements proceeded maintaining sustained moderate velocities for days before the catastrophic reactivation, making difficult to anticipate the acceleration

Background We have harnessed a novel biological system, the bacterial minicell, to deliver cancer therapeutics to cancer cells. Preclinical studies showed that epidermal growth factor receptor (EGFR)-targeted, paclitaxel-loaded minicells (EGFRminicellsPac) have antitumor effects in xenograft models. To examine the safety of the minicell delivery system, we initiated a first-time-in-human, open-label, phase I clinical study of EGFRminicellsPac in patients with advanced solid tumors. Methodology Patients received 5 weekly infusions followed by a treatment free week. Seven dose levels (1x108, 1x109, 3x109, 1x1010, 1.5x1010, 2x1010, 5x1010) were evaluated using a 3+3 dose-escalation design. Primary objectives were safety, tolerability and determination of the maximum tolerated dose. Secondary objectives were assessment of immune/inflammatory responses and antitumor activity. Principal Findings Twenty eight patients were enrolled, 22 patients completed at least one cycle of EGFRminicellsPac; 6 patients did not complete a cycle due to rapidly progressive disease. A total of 236 doses was delivered over 42 cycles, with a maximum of 45 doses administered to a single patient. Most common treatment-related adverse events were rigors and pyrexia. No deaths resulted from treatment-related adverse events and the maximum tolerated dose was defined as 1x1010 EGFRminicellsPac. Surprisingly, only a mild self-limiting elevation in the inflammatory cytokines IL-6, IL-8 and TNFα and anti-inflammatory IL-10 was observed. Anti-LPS antibody titers peaked by dose 3 and were maintained at that level despite repeat dosing with the bacterially derived minicells. Ten patients (45%; n = 22) achieved stable disease as their best response. Conclusions/Significance This is the first study in humans of a novel biological system that can provide targeted delivery of a range of chemotherapeutic drugs to solid tumor cells. Bispecific antibody-targeted minicells, packaged with the chemotherapeutic

In 2012 an emission feature at 220 cm(exp -1) in Titan's far-infrared spectrum was seen for the first time in the south. Attributed to a stratosphere ice cloud formed at the winter pole, the 220 (exp -1) emission had previously been seen only at high northern latitudes where it bad been decreasing since the arrival of Cassini in 2004. Our far-infrared observations were performed With the Composite Infrared Spectrometer (CIRS) on Caasini. Although it bad been expected that the 220 cm(exp -1) emission would eventnal1y appear in the south, the emission appeared rather suddenly, increasing by a factor of at least four between February (when it was not detected) and July 2012. At the time of our observations, one Titan month after equinox, the 220 cm(exp -1) feature was present in both the north and south and showed a trend of continued slow decrease in the north and steep increase in the south. As has been the case in the north, the emission in the south was confined to high latitudes associated with winter polar shadowing. Our spectroscopic detection of the southern 220 cm(exp -1) ice cloud coincided with the rapid formation in 2012 of a haze hood and vortex at the south pole as seen in Cassini image. The 220 cm(exp -1) feature was first observed by the Infrared Interferometer Spectrometer (IRIS) on Voyager I and has been extensively studied in the north by CIRS. Until now the 220 cm(exp -1) emission, like the polar hood, has been associated solely with the north, owing to the fact that Voyager and Cassini have viewed Titan only during winter-spring. In 2012 we witnessed the start of a seasonal shift of this pattern to the south. The 220 cm(exp -1) emission arises from altitudes of 80-150 km and peaks sharply near 140 km. The material responsible for the spectral feature is not known, but indirect evidence hints at a condensate arising from complex nitriles, which also tend to be present only at high winter latitudes.

The host-pathogen interactions induced by Salmonella Typhi and Salmonella Paratyphi A during enteric fever are poorly understood. This knowledge gap, and the human restricted nature of these bacteria, limit our understanding of the disease and impede the development of new diagnostic approaches. To investigate metabolite signals associated with enteric fever we performed two dimensional gas chromatography with time-of-flight mass spectrometry (GCxGC/TOFMS) on plasma from patients with S. Typhi and S. Paratyphi A infections and asymptomatic controls, identifying 695 individual metabolite peaks. Applying supervised pattern recognition, we found highly significant and reproducible metabolite profiles separating S. Typhi cases, S. Paratyphi A cases, and controls, calculating that a combination of six metabolites could accurately define the etiological agent. For the first time we show that reproducible and serovar specific systemic biomarkers can be detected during enteric fever. Our work defines several biologically plausible metabolites that can be used to detect enteric fever, and unlocks the potential of this method in diagnosing other systemic bacterial infections.

This study examined whether substance use disorders (SUD) and poverty predicted first-time suicide ideation or attempt in United States national data. Respondents without prior histories of suicide ideation or attempt at Wave 1 of the NESARC (N = 31,568) were analyzed to determine the main and interactive effects of SUD and poverty on first-time suicide ideation or attempt by Wave 2, 3 years later. Adjusted for controls, poverty (AOR = 1.35, CI = 1.05-1.73) and drug use disorders (AOR = 2.10, CI = 1.07-4.14) independently increased risk for first-time suicide ideation or attempt at Wave 2. SUD and poverty did not interact to differentially increase risk for first-time suicide ideation or attempt, prior to or after adjustment for controls. This study reinforces the importance of SUD and poverty in the risk for first-time suicide ideation or attempt. Public health efforts should target messages to drug users and the impoverished that highlight their increased risk for first-time suicide.

Enteric bacteria, including stocked strains of pathogenic species and organisms naturally present in the stream, were capable of growth in a chemostat with autoclaved river water taken 750 m below a sewage outfall. Maximal specific growth rates for all organisms occurred at 30 C, whereas culture generation times ranged between 33.3 and 116 hr. Of the six laboratory strains of enteric species used, Escherichia coli and Enterobacter aerogenes grew at generation times of 34.5 and 33.3 hr, respectively, while the remaining Proteus, Arizona, Salmonella, and Shigella spp. reproduced at a rate two to three times slower than the coliforms. Little or no growth occurred in the water at incubation temperatures of 20 and 5 C, and death was observed for Salmonella senftenberg at 20 and 5 C and for E. aerogenes and Proteus rettgeri at 5 C. When enteric bacteria naturally present in the river water were employed in similar experiments, coliform bacteria demonstrated a generation time of approximately 116 hr, whereas fecal coliforms failed to grow. Growth of the bacteria from the river demonstrated a periodicity of approximately 100 hr, which suggests that much of the growth of these organisms in the chemostat may be on the glass surfaces. This phenomenon, however, was not observed with any of the stocked enteric species. Neither the stock cultures nor the aquatic strains were capable of growth in autoclaved river water taken above the sewage outfall at the three temperatures tested.

The history of percutaneous endoscopic gastrostomy (PEG) is relatively short. In 1980, a report entitled "Gastrostomy without laparotomy: A percutaneous endoscopic technique" by Ponsky and Gaudere was first published in the Journal of Pediatric Surgery. Thereafter, PEG soon saw widespread use in Western countries because of its clinical efficacy and economy. It has been performed in about 170,000 cases annually in the US. In contrast, its spread in Japan has been extremely slow: only about 10,000 cases have undergone this procedure annually, and this number accounted for less than 5% of patients receiving enteral alimentation. The reason why PEG has not spread may be the medical insurance system in Japan and the local distaste for operation scarring. However, in consideration of the unprecedented ageing of society that is surely coming in the near future, the role of PEG in Japan must be reexamined. In this report, we presented the methodology of enteral alimentation at home by means of PEG, giving special consideration to: (1) "What points are improved by using enteral alimentation at home by means of PEG in various diseases; (2) dysphagia due to cerebral angiopathy; (3) terminal cancer; (4) otolaryngological diseases; and (5) Crohn disease. We also discussed "Why PEG is important now?" in performing enteral alimentation at home.

The hypermetabolism that develops in patients with severe polytraumatism has led to the need for an aggressive metabolic-nutritional support from the start. Parenteral Nutrition is the preferred technique in many instances, due to the doubts on the effectiveness of enteral nutrition in the control of the metabolic response and to problems of gastrointestinal tolerance derived from its administration. However, the role of enteral nutrition as an important factor which limits the development of bacterial translocation and the chain of events leading to multiorganic failure appears to be more and more well-established and is an important argument for justifying the early administration of enteral nutrition in these patients. In accordance with the accumulated experience of several authors over the past few years, enteral nutrition may be administered early in polytraumatized patients. This is not only accompanied by the evidence of acceptable gastrointestinal tolerance to the diet, but also by additional advantages compared to parenteral nutrition, such as the maintenance of trophism and immunocompetence of the digestive mucosa, the reduction of septic complications and also greater nutritional effectiveness which can be evaluated by the behaviour of the seric proteins used as nutritional evolution markers. The interest of the different diet formulae which exist at present, for example diets enriched with branched-chain amino acids, diets with added fibre, peptidic diets, specific pulmonary diets or "euglycaemic diets" is evaluated in this review. All these diets may mean an increase in the effectiveness and/or tolerance of enteral nutrition in polytraumatized patients, and also contribute to the handling of specific problems such as "stress" hyperglycaemia or the withdrawal of mechanical ventilation support. The use of specific nutrients for the digestive mucosa, such as glutamine or short chain fatty acids seems to be an important factor in the reduction of

Aquaporin-4 is a water channel predominantly found in astrocytes in the central nervous system and is believed to play a critical role in the formation and maintenance of the blood–brain barrier and in water secretion from the brain. As enteric glial cells were found to share several similarities with astrocytes, we hypothesized that enteric glia might also contain aquaporin-4. We used immunohistochemistry to identify aquaporin-4 in the myenteric and submucosal plexuses of the mouse and the rat colon. We found that sub-populations of neurons in both enteric plexuses were positively labeled for human aquaporin-4. Double staining of the enteric ganglia with antibodies to the neuronal marker neurofilament–heavy chain 100 and to aquaporin-4 showed that a minority of myenteric neurons were aquaporin-4 positive (about 12% in the mouse and 13% in the rat). In contrast, in the submucosal plexus significant numbers of neurons were positive for aquaporin-4 (about 79% in both the mouse and the rat). Double labeling for aquaporin-4 and for the glial marker glial fibrillary acidic protein verified that glial cells were not immunoreactive to aquaporin-4. We further confirmed our findings with additional aquaporin-4 antibodies and Western blot analysis. We found that, in addition to expressing aquaporin-4, the myenteric plexus and, to a greater extent, the submucosal plexus both expressed aquaporin-1. We conclude that neurons rather than glial cells contain aquaporin-4 in the colonic enteric plexuses. It is known that submucosal neurons control transport processes in the intestinal mucosa, and the high percentage of aquaporin-4-postive sub-mucosal neurons suggests that aquaporin-4 contributes to this function.

This retrospective descriptive correlational study compared the predictive accuracy of the Health Education Systems, Inc, Exit Exam (Elsevier) and Assessment Technologies Institute's RN Comprehensive Predictor, both of which were administered to nursing students in an upper-division baccalaureate nursing program during their final semester of study. Using logistic regression analyses, it was determined that the two examinations were statistically significant but weak predictors of success on the RN licensure examination. The RN Comprehensive Predictor had a slightly better odds ratio; however, both examinations had similar sensitivity, specificity, and overall accuracy. Because the RN Comprehensive Predictor was included in the Assessment Technologies Institute's Comprehensive Assessment and Review Program already being used by the BSN program, based on the results of this study, the nursing faculty decided to use only the RN Comprehensive Predictor during its NCLEX-RN preparation course.
The ability to predict the success of students when they enter a graduate program is critical for educational institutions because it allows them to develop strategic programs that will help improve students' performances during their stay at an institution. In this study, we present the results of an experimental comparison study of Logistic…

It is now widely acknowledged that the intestinal bacterial flora together with genetic predisposing factors significantly contribute to the immunopathogenesis of inflammatory bowel disease (IBD) as reflected by mucosal immune dysregulation. Recently, there has been an increased interest in nutraceutical therapies, including probiotics, prebiotics and synbiotics. Other dietary interventions with low carbohydrate diet, omega-3 polyunsaturated fatty acids and glutamine have been attempted to downregulate the gut inflammatory response and thereby alleviate gastrointestinal symptoms. Enteral nutrition has been widely used as induction and maintenance therapies in the management of Crohn's disease (CD). In this review, a critical assessment of the results of clinical trial outcomes and meta-analyses was conducted to evaluate the efficacy of dietary and enteral interventions for CD.

The clinical and nutritional significance of radiation enteritis was assessed in eight patients with chronic diarrhea which followed curative doses of radiotherapy for pelvic malignancies. Steatorrhea, found in seven malnourished patients, was ascribed to ileal disease or previous surgery, or to bacterial contamination of the small intestine. Lactose intolerance, assessed by breath hydrogen excretion after oral lactose and by jejunal lactase levels, was found in six patients. In a subgroup of five patients, the administration of two different defined formula liquid diets by nasoduodenal infusion decreased fecal fluid and energy losses by about one-half. Compared to Vivonex-HN, the infusion of Criticare-HN was associated with greater likelihood of intestinal gas production but a three-fold greater utilization of protein. Intestinal malabsorption and malnutrition in radiation enteritis has diverse etiologies. Whereas nutritional support by liquid diet limits fecal fluid and energy losses, these diets differ significantly in clinical tolerance and biologic value.

Diarrhoea in lambs and kids is often a complex, multi-factorial syndrome. Common infectious causes of diarrhoea in lambs and kids during the first month of life are of bacterial or parasite nature. However, despite appreciable improvements in management practices and prevention and treatment strategies over the last decades, diarrhoea is still a common and costly syndrome affecting newborn small ruminants. Recent advances in the diagnostics and metagenomic investigations of the enteric environment have allowed discovering a number of novel viruses, although their pathobiological properties remain largely unknown. Assessing more in depth the impact of these viruses on the health and productions of these livestock animals is necessary and requires the development of accurate diagnostic tools and updating of the diagnostic algorithms of enteric pathological conditions.

Human immune deficient virus (HIV) is an immunosuppressive virus that targets CD4(+) T-lymphocytes. HIV infections cause increased susceptibility to opportunistic infections and cancer. HIV infection can also alter central nervous system (CNS) function causing cognitive impairment. HIV does not infect neurons but it does infect astrocytes and microglia in the CNS. HIV can also infect enteric glia initiating an intestinal inflammatory response which causes enteric neural injury and gut dysfunction. Part of the inflammatory response is HIV induced production of proteins including, Transactivator of transcription (Tat) which contribute to neuronal injury after release from HIV infected glial cells. A risk factor for HIV infection is intravenous drug use with contaminated needles and chronic opiate use can exacerbate neural injury in the nervous system. While most research focuses on the actions of Tat and other HIV related proteins and opiates on the brain, recent data indicate that Tat can cause intestinal inflammation and disruption of enteric neuron function, including alteration of Na(+) channel activity and action potential generation. A paper published in this issue of Neurogastroenterology and Motility extends these findings by identifying an interaction between Tat and morphine on enteric neuron Na(+) channels and on intestinal motility in vivo using a Tat expressing transgenic mouse model. These new data show that Tat protein can enhance the inhibitory actions of morphine on action potential generation and propulsive motility. These findings are important to our understanding of how HIV causes diarrhea in infected patients and for the use of opioid drugs to treat HIV-induced diarrhea.

Introduction Oesophagectomy for cancer is a challenging procedure with a five-year overall survival rate of 15-20%. Early enteral nutrition following oesophagectomy is a crucial component of the postoperative recovery and carries a significant impact on the outcome. Different methods of enteral feeding were conducted in our unit. The aim of this study was to examine the efficacy and safety of nasojejunal tube (NJT), jejunostomy tube (JT) and pharyngostomy tube (PT) feeding after oesophagectomy. Methods A retrospective review was carried out of prospectively collected data on patients with oesophageal cancer who underwent an oesophagectomy between 2011 and 2014. The primary outcome was feeding tube related complications such as occlusion, dislocation and leak. The secondary outcomes were length of stay and 30-day morbidity. Results A total of 90 oesophagectomies were included in the study. A NJT was inserted in 41 patients (45.6%), a JT was used in 14 patients (15.5%) and a PT was the route for enteral nutrition in 35 patients (38.9%). In total, five patients (5.5%) developed tube related complications. There were no tube related complications in the NJT group but one JT patient (7.1%) developed tube related cellulitis (p=0.189) and four PT patients (11.4%) developed tube related haemorrhage (p=0.544), tube dislocation (p=0.544) or cellulitis (p=0.189). The median length of stay and 30-day postoperative morbidity were similar between the groups. Conclusions NJT feeding is a less invasive, feasible route for early enteral nutrition following oesophagectomy. A randomised controlled trial is recommended to verify these findings.

Background: Environmental exposures to chemicals have been shown to influence gastrointestinal function, yet little is known regarding whether chemical mixtures may be involved in the development of a subclinical enteric dysfunction found in infants and children born into poor hygiene and sanitation. Advances in gastrointestinal and immunotoxicology fields merit inclusion in complex discussions of environmental enteric dysfunction (EED) that severely affects children in developing countries. Objective: We aimed to highlight exposome approaches for investigating the potential influence of environmental chemical exposures on EED development, including a role for toxicant modulation of gut immune system and microbiome function. Discussion: A major focus on fecal–oral contamination in impoverished living conditions already exists for EED, and should now expand to include environmental chemicals such as pesticides and heavy metals that may be anthropogenic or dietary or from microbial sources. A comprehensive characterization of environmental chemical exposures prenatally and occurring in infants and young children will enhance our knowledge of any associated risks for EED and stunting. Conclusions: Integrating EED, chemical exposure, and stunting at various ages during childhood will enhance our apparent limited view when evaluating EED. Etiology and intervention studies should evaluate the suite of environmental chemical exposures as candidates in the composite of EED biomarkers. Citation: Mapesa JO, Maxwell AL, Ryan EP. 2016.

A formulary for enteral nutrition products was developed at a university hospital. Advice was solicited from clinical dietetics and the medical staff. Reported important product variables were osmolality, caloric density, protein content and source, fat content and source, freedom from lactose, and, for oral supplements, available flavors. Data were also obtained from manufacturers regarding the composition of their products. Products were categorized as follows: liquid supplemental feedings, high calorie supplemental feedings, isotonic tube feedings, high caloric/high nitrogen tube feedings, high nitrogen tube feedings, and blenderized tube feedings. Bids were solicited in April 1981 (and annually thereafter) from manufacturers of the classified enteral nutrition products, and a contract was signed with the manufacturer in each category submitting the lowest bid. In contrast with previous experience, there was no loss from outdated products during the first year of the formulary. Categorizing enteral nutrition products into therapeutic categories appears to be a workable method to limit the number of products used in a hospital, thereby potentially decreasing inventory, waste, and hospital costs. The descriptive category titles also may encourage rational use of these products without promoting allegiance to a particular company or product.

The aim of this systematic review is to evaluate the role of enteral nutrition in dementia. The prevalence of dementia is predicted to rise worldwide partly due to an aging population. People with dementia may experience both cognitive and physical complications that impact on their nutritional intake. Malnutrition and weight loss in dementia correlates with cognitive decline and the progress of the disease. An intervention for long term eating difficulties is the provision of enteral nutrition through a Percutaneous Endoscopic Gastrostomy tube to improve both nutritional parameters and quality of life. Enteral nutrition in dementia has traditionally been discouraged, although further understanding of physical, nutritional and quality of life outcomes are required. The following electronic databases were searched: EBSCO Host, MEDLINE, PubMed, Cochrane Database of Systematic Reviews and Google Scholar for publications from 1st January 2008 and up to and including 1st January 2014. Inclusion criteria included the following outcomes: mortality, aspiration pneumonia, pressure sores, nutritional parameters and quality of life. Each study included separate analysis for patients with a diagnosis of dementia and/or neurological disease. Retrospective and prospective observational studies were included. No differences in mortality were found for patients with dementia, without dementia or other neurological disorders. Risk factors for poor survival included decreased or decreasing serum albumin levels, increasing age or over 80 years and male gender. Evidence regarding pneumonia was limited, although did not impact on mortality. No studies explored pressure sores or quality of life. PMID:25854831

Introduction Little is known about HIV testing, HIV infection and sexual behaviour among bathhouse patrons in China. This study aims to assess differences in HIV prevalence and high-risk sexual behaviours between repeat and first-time testers among men who have sex with men (MSM) attending bathhouse in Tianjin, China. Methods Between March 2011 and September 2012, a HIV voluntary counselling and testing station was established in a gay bathhouse, which provided HIV testing and conducted a survey among participants recruited through snowball sampling. Differences in demographic and high-risk sexual behaviours between repeat and first-time testers were assessed using the chi-square test. Univariate and multivariate logistic regression analyses were conducted to identify predictors for HIV infection. Results Of the 1642 respondents, 699 (42.6%) were repeat testers and 943 (57.4%) were first-time testers. Among repeat testers, a higher proportion were men aged 18 to 25, single, better educated, had a history of STIs and worked as male sex workers or “money boys” (MBs). Repeat testers were less likely to report having unprotected anal intercourse in the past six months. The overall HIV prevalence was 12.4% (203/1642). There was no difference in HIV prevalence between repeat (11.2%, 78/699) and first-time (13.3%, 125/943) testers. The HIV prevalence increased with age among first-time testers (χtrend2=9.816, p=0.002). First-time MB testers had the highest HIV prevalence of 34.5%. Conclusions MSM attending bathhouse had an alarmingly high HIV infection rate, particularly in MB. Targeted interventions are urgently needed especially focusing on older MSM and MBs. PMID:24993457

The avian enteric nervous system (ENS) consists of a vast number of unusually small ganglia compared to other peripheral ganglia. Each ENS ganglion at mid-gestation has a core of neurons and a shell of mesenchymal precursor/glia-like enteric neural crest (ENC) cells. To study ENS cell ganglionation we isolated midgut ENS cells by HNK-1 fluorescence-activated cell sorting (FACS) from E5 and E8 quail embryos, and from E9 chick embryos. We performed cell-cell aggregation assays which revealed a developmentally regulated functional increase in ENS cell adhesive function, requiring both Ca 2+ -dependent and independent adhesion. This was consistent with N-cadherin and NCAM labelling. Neurons sorted to the core of aggregates, surrounded by outer ENC cells, showing that neurons had higher adhesion than ENC cells. The outer surface of aggregates became relatively non-adhesive, correlating with low levels of NCAM and N-cadherin on this surface of the outer non-neuronal ENC cells. Aggregation assays showed that ENS cells FACS selected for NCAM-high and enriched for enteric neurons formed larger and more coherent aggregates than unsorted ENS cells. In contrast, ENS cells of the NCAM-low FACS fraction formed small, disorganised aggregates. This suggests a novel mechanism for control of ENS ganglion morphogenesis where i) differential adhesion of ENS neurons and ENC cells controls the core/shell ganglionic structure and ii) the ratio of neurons to ENC cells dictates the equilibrium ganglion size by generation of an outer non-adhesive surface.

Background Gastrointestinal symptoms are not an uncommon manifestation of an influenza virus infection. In the present study, we aimed to investigate the presence of influenza viruses in the stools of adult patients consulting their general practitioner for uncomplicated acute diarrhea (AD) and the proportion of concurrent infections by enteric and influenza viruses. Method A case-control study was conducted from December 2010 to April 2011. Stool specimens were collected and tested for influenza viruses A (seasonal A/H3N2 and pandemic A/H1N1) and B, and for four enteric viruses (astrovirus, group A rotavirus, human enteric adenovirus, norovirus of genogroups I – NoVGI - and genogroup II - NoVGII). Results General practitioners enrolled 138 cases and 93 controls. Of the 138 stool specimens collected, 92 (66.7%) were positive for at least one of the four enteric viruses analysed and 10 (7.2%) tested positive for one influenza virus. None of these 10 influenza positive patients reported respiratory symptoms. In five influenza-positive patients (3.6%), we also detected one enteric virus, with 4 of them being positive for influenza B (2 had co-detection with NoVGI, 1 with NoVGII, and 1 with astrovirus). None of the 93 controls tested positive for one of the enteric and/or other influenza viruses we investigated. Conclusions In this study we showed that the simultaneous detection of influenza and enteric viruses is not a rare event. We have also reported, for the first time in general practice, the presence of seasonal and pandemic influenza viruses in the stools of adult patients consulting for uncomplicated AD. A simultaneous investigation of enteric and influenza viruses in patients complaining of gastrointestinal symptoms could be useful for future studies to better identify the agents responsible for AD.

African swine fever (ASF) is caused by a large and highly pathogenic DNA virus, African swine fever virus (ASFV), which provokes severe economic losses and expansion threats. Presently, no specific protection or vaccine against ASF is available, despite the high hazard that the continued occurrence of the disease in sub-Saharan Africa, the recent outbreak in the Caucasus in 2007, and the potential dissemination to neighboring countries, represents. Although virus entry is a remarkable target for the development of protection tools, knowledge of the ASFV entry mechanism is still very limited. Whereas early studies have proposed that the virus enters cells through receptor-mediated endocytosis, the specific mechanism used by ASFV remains uncertain. Here we used the ASFV virulent isolate Ba71, adapted to grow in Vero cells (Ba71V), and the virulent strain E70 to demonstrate that entry and internalization of ASFV includes most of the features of macropinocytosis. By a combination of optical and electron microscopy, we show that the virus causes cytoplasm membrane perturbation, blebbing and ruffles. We have also found that internalization of the virions depends on actin reorganization, activity of Na+/H+ exchangers, and signaling events typical of the macropinocytic mechanism of endocytosis. The entry of virus into cells appears to directly stimulate dextran uptake, actin polarization and EGFR, PI3K-Akt, Pak1 and Rac1 activation. Inhibition of these key regulators of macropinocytosis, as well as treatment with the drug EIPA, results in a considerable decrease in ASFV entry and infection. In conclusion, this study identifies for the first time the whole pathway for ASFV entry, including the key cellular factors required for the uptake of the virus and the cell signaling involved.

Enteric viruses are a major problem in the food industry, especially as human noroviruses are the leading cause of nonbacterial gastroenteritis. Chitosan is known to be effective against some enteric viral surrogates, but more detailed studies are needed to determine the precise application variables. The main objective of this work was to determine the effect of increasing chitosan concentration (0.7-1.5% w/v) on the cultivable enteric viral surrogates, feline calicivirus (FCV-F9), murine norovirus (MNV-1), and bacteriophages (MS2 and phiX174) at 37 °C. Two chitosans (53 and 222 kDa) were dissolved in water (53 kDa) or 1% acetic acid (222 KDa) at 0.7-1.5%, and were then mixed with each virus to obtain a titer of ~5 log plaque-forming units (PFU)/mL. These mixtures were incubated for 3 h at 37 °C. Controls included untreated viruses in phosphate-buffered saline and viruses were enumerated by plaque assays. The 53 kDa chitosan at the concentrations tested reduced FCV-F9, MNV-1, MS2, and phi X174 by 2.6-2.9, 0.1-0.4, 2.6-2.8, and 0.7-0.9 log PFU/mL, respectively, while reduction by 222 kDa chitosan was 2.2-2.4, 0.8-1.0, 2.6-5.2, and 0.5-0.8 log PFU/mL, respectively. The 222 kDa chitosan at 1 and 0.7% w/v in acetic acid (pH 4.5) caused the greatest reductions of MS2 by 5.2 logs and 2.6 logs, respectively. Overall, chitosan treatments showed the greatest reduction of MS2, followed by FCV-F9, phi X174, and MNV-1. These two chitosans may contribute to the reduction of enteric viruses at the concentrations tested but would require use of other hurdles to eliminate food borne viruses.

Enteric hyperoxaluria is a common occurrence in the setting of fat malabsorption, usually due to intestinal resection or intestinal bypass surgery. Enhanced intestinal absorption of dietary oxalate leads to elevated renal oxalate excretion, frequently in excess of 100 mg/d (1.14 mmol/d). Patients are at increased risk of urolithiasis and loss of kidney function from oxalate nephropathy. Fat malabsorption causes increased binding of diet calcium by free fatty acids, reducing the calcium available to precipitate diet oxalate. Delivery of unabsorbed bile salts and fatty acids to the colon increases colonic permeability, the site of oxalate hyper-absorption in enteric hyperoxaluria. The combination of soluble oxalate in the intestinal lumen and increased permeability of the colonic mucosa leads to hyperoxaluria. Dietary therapy consists of limiting oxalate and fat intake. The primary medical intervention is the use of oral oxalate binding agents such as calcium salts to reduce free intestinal oxalate levels. Bile acid sequestrants can be useful in patients with ileal resection and bile acid malabsorption. Oxalate degrading bacteria provided as probiotics are being investigated but as of yet, no definite benefit has been shown with currently available preparations. The current state of medical therapy and potential future directions will be summarized in this article.

The response of enteric vasculature to endotoxin was examined at the ultrastructural level using a murine model of endotoxin-induced acute diarrhoea. Morphological changes indicative of endothelial damage were evident as early as 15 minutes following endotoxin challenge. These changes, characterized by widening of intercellular spaces, increased microvillous projections and the appearance of stress fibres, preceded the leucocytic response. Endothelial damage increased with time, being associated with progressive degenerative changes in the plasma membrane, cytoplasm and organelles, ultimately leading to desquamation. These latter changes were temporally associated with margination of neutrophils and platelet adhesion to the denuded subendothelium. The venules were the primary site of these changes while the capillaries were the least affected. The arterioles were markedly constricted with minimal endothelial damage. These changes suggest that the enteric vascular endothelium may be an important target organ, and the resultant endothelial injury may have implications in host responses to endotoxin.

We report the case of a young woman with a background history of discoid lupus who presented with abdominal pain, vomiting and intermittent diarrhoea. Physical examination revealed tenderness in the right upper quadrant with a palpable right inguinal lymph node without any other clinical signs of active lupus. Laboratory investigations showed normal inflammatory markers, positive ANA and Anti-Ro antibodies, persistent hypocomplementemia and lymphopenia, CT showed marked bowel oedema involving the small and large bowel (halo sign) with massive ascites and moderate right-sided pleural effusion. Mantoux test, AFB and TB cultures were negative. A diagnosis of lupus enteritis was made and treatment with high-dose steroids was commenced with little improvement. Treatment with cyclophosphamide was discussed but declined by the patient. Mycophenolate mofetil was commenced and resulted in significant clinical and radiological resolution. To the best of the authors' knowledge this is the first report of the successful use of mycophenolate mofetil in inducing and maintaining remission in lupus enteritis.

As the role of 2YC (two-year colleges/community colleges) changes in the academic pipeline of higher education new practices and ideas to engage and retain students in the geosciences at the 2YC level need to be explored. 2YC typically have a student body composed of non-traditional students ranging from second career students, single parents, students with disabilities, seniors, and minorities. Currently, 2YCs serve 44% of all undergraduate students and 45% of all of all first time freshmen in the US. These statistics show the potential community colleges hold to encourage entering students to the STEM (Science Technology Engineering and Math) fields as a possible career choice. But the reality is the number of STEM degrees awarded at community colleges has not followed the same trends in student enrollment. Over the past four years El Paso Community College (EPCC) in conjunction with The University of Texas at El Paso (UTEP) has implemented several initiatives in our effort to increase the number of Geological Science majors at EPCC and to ensure a successful transition to UTEP. These efforts are aimed to decrease attrition rates of science majors by; articulating degree plans between institutions, introduce field-based research projects to allow hands on experience for students, develop a working relationship between students and university faculty, diversify geology courses offered at EPCC, and strengthening the educational-bridge between the geological science departments of EPCC and UTEP through the aid of federally funded programs. The success of the these efforts have been seen by; the increase in geology majors in our A.S. degree program, the number of degrees conferred at EPCC, the successful transition of students to UTEP, and graduation of students from UTEP with advanced degrees.

Twenty-two flocks of turkeys affected by enteric problems, with ages between 10 and 104 days and located in the Southern region of Brazil, were surveyed for turkey by PCR for turkey astrovirus type 2 (TAstV-2), turkey coronavirus (TCoV), hemorrhagic enteritis virus (HEV), rotavirus, reovirus, Salmonella spp., and Lawsonia intracellularis (Li) infections. Eleven profiles of pathogen combination were observed. The most frequently encountered pathogen combinations were TCoV-Li, followed by TCoV-TAstV-2-Li, TCoV-TastV-2. Only TCoV was detected as the sole pathogen in three flocks. Eight and 19 flocks of the 22 were positive for TAstV-2 and TCoV, respectively. Six were positive for Salmonella spp. and L. intracellularis was detected in 12 turkey flocks. Reovirus and HEV were not detected in this survey. These results throw new light on the multiple etiology of enteritis in turkeys. The implications of these findings and their correlation with the clinical signs are comprehensively discussed, illustrating the complexity of the enteric diseases.

Apollo 10 lunar module pilot Eugene A. Cernan prepares to enter the lunar module simulator at the Flight Crew Training Building at the NASA Spaceport. Cernan, Apollo 10 commander Thomas P. Stafford and John W. Young, command module pilot, are to be launched May 18 on the Apollo 10 mission, a dress rehearsal for a lunar landing later this summer. Cernan and Stafford are to detach the lunar module and drop to within 10 miles of the moon's surface before rejoining Young in the command/service module. Looking on as Cernan puts on his soft helmet is Snoopy, the lovable cartoon mutt whose name will be the lunar module code name during the Apollo 10 flight. The command/service module is to bear the code name Charlie Brown.

To evaluate the gastric emptying time of pharmaceutical dosage forms in a clinical setting, a relatively simple dual-radionuclide technique was developed. Placebo tablets of six different combinations of shape and size were labeled with indium-111 DTPA and enteric coated. Six volunteers participated in a single-blind and crossover study. Tablets were given in the morning of a fasting stomach with 6 oz of water containing /sup 99m/Tc pertechnetate and continuously observed with a gamma camera. A scintigraph was obtained each minute. The results suggested that the size, shape, or volume of the tablet used in this study had no significant effect in the rate of gastric emptying. The tablets emptied erratically and unpredictably, depending upon their time of arrival in the stomach in relation to the occurrence of interdigestive myoelectric contractions. The method described is a relatively simple and accurate technique to allow one to follow the gastric emptying of tablets.

Diarrheal diseases are a major cause of childhood death in resource-poor countries, killing about 760, 000 children under age 5 each year. While deaths due to diarrhea have declined dramatically, high rates of stunting and malnutrition have persisted. Environmental Enteric Dysfunction (EED) is a subclinical condition caused by constant fecal-oral contamination with resultant intestinal inflammation and villous blunting. These histological changes were first described in the 1960’s but the clinical impact of EED is only just being recognized in the context of failure of nutritional interventions and oral vaccines in resource-poor countries. We review the existing literature regarding the underlying causes of and potential interventions for EED and poor growth in children, highlighting the epidemiology, clinical and histologic classification of the entity, as well as discussing novel biomarkers and possible therapies. Future research priorities are also discussed. PMID:26974416
First, I believe we're entering an era of synthesis of modeling. Over the past 20 years, we've seen the proliferation of many isolated complex systems models. I think we now need tools for researchers, policy makers and the public to share models. Sharing could happen by stacking different layers of spatial agent-based models in geographic information systems and projecting interactive visualization out onto shared surfaces. Further, we need to make model authoring tools much more accessible to the point where motivated policy makers can author on their own. With the increased ability to author and share models, I believe this will allow us to scale our research to understand and manage the many interacting systems that make up our complex world...

The enteric nervous system (ENS) autonomously controls gut muscle activity. Mechanosensitive enteric neurons (MEN) initiate reflex activity by responding to mechanical deformation of the gastrointestinal wall. MEN throughout the gut primarily respond to compression or stretch rather than to shear force. Some MEN are multimodal as they respond to compression and stretch. Depending on the region up to 60% of the entire ENS population responds to mechanical stress. MEN fire action potentials after mechanical stimulation of processes or soma although they are more sensitive to process deformation. There are at least two populations of MEN based on their sensitivity to different modalities of mechanical stress and on their firing pattern. (1) Rapidly, slowly and ultra-slowly adapting neurons which encode compressive forces. (2) Ultra-slowly adapting stretch-sensitive neurons encoding tensile forces. Rapid adaptation of firing is typically observed after compressive force while slow adaptation or ongoing spike discharge occurs often during tensile stress (stretch). All MEN have some common properties: they receive synaptic input, are low fidelity mechanoreceptors and are multifunctional in that some serve interneuronal others even motor functions. Consequently, MEN possess processes with mechanosensitive as well as efferent functions. This raises the intriguing hypothesis that MEN sense and control muscle activity at the same time as servo-feedback loop. The mechanosensitive channel(s) or receptor(s) expressed by the different MEN populations are unknown. Future concepts have to incorporate compressive and tensile-sensitive MEN into neural circuits that controls muscle activity. They may interact to control various forms of a particular motor pattern or regulate different motor patterns independently from each other. PMID:26528136

Abstract Potential consequences of lowering voting age to 16 have been discussed in recent scientific and public debates. This article examines turnout of young voters aged 16 to 17 in Austria, the first European country that lowered the general voting age to 16. For this purpose we use unique data taken from electoral lists of two recent Austrian regional elections. The results support the idea that the so-called “first-time voting boost” is even stronger among the youngest voters as turnout was (a) higher compared to 18- to 20-year-old first-time voters and (b) not substantially lower than the average turnout rate. We conclude that our findings are encouraging for the idea of lowering voting age as a means to establish higher turnout rates in the future. PMID:27226806

Male partners' involvement in women's sexual and reproductive health has been increasingly emphasised in international health. A qualitative approach with open-ended qualitative interviews was used to explore young, married men's first time experiences of early childbearing, their sexual and reproductive decision making and the meanings they make of their role as husbands and fathers. The results offer a nuanced picture of the men's vulnerability in becoming young fathers and having to assume their role as family decision-makers, while still being inexperienced in matters related to the health of their wives and newborn child. Constraints to gender equality and traditional norms and values continue to pose barriers to both young men and women making independent decisions in relation to marriage and childbearing. Men's involvement is necessary in healthcare programmes designed to improve women's sexual and reproductive health and the health of the newborn. Young, first-time fathers, in particular, need support and empowerment.

Introduction: This study evaluates the clinical benefit of magnetic resonance-transrectal ultrasound (MR-TRUS) fusion biopsy over systematic biopsy between first-time and repeat prostate biopsy patients with prior atypical small acinar proliferation (ASAP). Materials: 100 patients were enrolled in a single-centre prospective cohort study: 50 for first biopsy, 50 for repeat biopsy with prior ASAP. Multiparameteric magnetic resonance imaging (MP-MRI) and standard 12-core ultrasound biopsy (Std-Bx) were performed on all patients. Targeted biopsy using MRI-TRUS fusion (Fn-Bx) was performed f suspicious lesions were identified on the pre-biopsy MP-MRI. Classification of clinically significant disease was assessed independently for the Std-Bx vs. Fn-Bx cores to compare the two approaches. Results: Adenocarcinoma was detected in 49/100 patients (26 first biopsy, 23 ASAP biopsy), with 25 having significant disease (17 first, 8 ASAP). Fn-Bx demonstrated significantly higher per-core cancer detection rates, cancer involvement, and Gleason scores for first-time and ASAP patients. However, Fn-Bx was significantly more likely to detect significant cancer missed on Std-Bx for ASAP patients than first-time biopsy patients. The addition of Fn-Bx to Std-Bx for ASAP patients had a 166.7% relative risk reduction for missing Gleason ≥ 3 + 4 disease (number needed to image with MP-MRI=10 patients) compared to 6.3% for first biopsy (number to image=50 patients). Negative predictive value of MP-MRI for negative biopsy was 79% for first-time and 100% for ASAP patients, with median followup of 32.1 ± 15.5 months. Conclusions: MR-TRUS Fn-Bx has a greater clinical impact for repeat biopsy patients with prior ASAP than biopsy-naïve patients by detecting more significant cancers that are missed on Std-Bx.

The greenhouse gas (GHG) emissions from the agricultural sector account for about 25.5% of total global anthropogenic emission. While CO(2) receives the most attention as a factor relative to global warming, CH(4), N(2)O and chlorofluorocarbons (CFCs) also cause significant radiative forcing. With the relative global warming potential of 25 compared with CO(2), CH(4) is one of the most important GHGs. This article reviews the prediction models, estimation methodology and strategies for reducing enteric CH(4) emissions. Emission of CH(4) in ruminants differs among developed and developing countries, depending on factors like animal species, breed, pH of rumen fluid, ratio of acetate:propionate, methanogen population, composition of diet and amount of concentrate fed. Among the ruminant animals, cattle contribute the most towards the greenhouse effect through methane emission followed by sheep, goats and buffalos, respectively. The estimated CH(4) emission rate per cattle, buffaloe, sheep and goat in developed countries are 150.7, 137, 21.9 and 13.7 (g/animal/day) respectively. However, the estimated rates in developing countries are significantly lower at 95.9 and 13.7 (g/animal/day) per cattle and sheep, respectively. There exists a strong interest in developing new and improving the existing CH(4) prediction models to identify mitigation strategies for reducing the overall CH(4) emissions. A synthesis of the available literature suggests that the mechanistic models are superior to empirical models in accurately predicting the CH(4) emission from dairy farms. The latest development in prediction model is the integrated farm system model which is a process-based whole-farm simulation technique. Several techniques are used to quantify enteric CH(4) emissions starting from whole animal chambers to sulfur hexafluoride (SF6) tracer techniques. The latest technology developed to estimate CH(4) more accurately is the micrometeorological mass difference technique. Because

Parvovirus enteritis developed in 10 of 17 vaccinated juvenile bush dogs (Speothos venaticus) from 4 litters in a 5-month period. Nine dogs died. The first outbreak involved 6 of 9 bush dogs from 2 litters. Each had been vaccinated with a killed feline-origin parvovirus vaccine at 11 and 14 weeks of age. The 6 affected dogs became ill at 29 weeks of age and died. The second outbreak involved a litter of 6 bush dogs. Each had been vaccinated every 2 weeks starting at 5 weeks of age. Two were isolated from the colony at 16 weeks of age for treatment of foot sores. Three of the 4 nonisolated dogs developed parvovirus enteritis at 20 weeks of age; 2 died at 6 and 8 days, respectively, after onset of signs. The 3rd outbreak involved a litter of 2 bush dogs. Both had been vaccinated every 2 to 3 weeks, starting at 6 weeks of age. One of these dogs became ill at 17 weeks and died 13 days later. A litter of 6 maned wolves (Chrysocyon brachyurus) and a litter of 3 bush dogs were isolated from their parent colonies at 13 and 15 weeks of age, respectively. Each animal had been vaccinated weekly, beginning at 8 weeks of age, using an inactivated canine-origin parvovirus vaccine. None of the isolated animals developed the disease. Serologic testing during isolation did not reveal protective titers (greater than or equal to 1:80) against canine parvovirus in the bush dogs until they were 23 weeks old, whereas protective titers developed in the maned wolves when they were 14 to 18 weeks old. One hand-raised bush dog was vaccinated weekly, beginning at 8 weeks of age, and a protective titer developed by 21 weeks of age. It was concluded that the juvenile bush dogs went through a period during which maternal antibodies interfered with immunization, yet did not protect against the disease. When the pups were isolated from the colony during this period, then vaccinated repeatedly until protective titers developed, the disease was prevented.

The objective of this study was to investigate the properties of enteric matrix pellets that were prepared by hot-melt extrusion in a one-step, continuous process. Five polymers (Eudragit) L100-55, L100 and S100, Aqoat grades LF and HF) were investigated as possible matrix formers, and pellets prepared with Eudragit S100 demonstrated superior gastric protection and acceptable processibility. Extruded pellets containing Eudragit S100 and up to 40% theophylline released less than 10% drug over 2h in acid, however, the processibility and yields were compromised by the high amounts of the non-melting drug material in the formulation. Efficient plasticization of Eudragit S100 was necessary to reduce the polymer's glass transition temperature and melt viscosity. Five compounds including triethyl citrate, methylparaben, polyethylene glycol 8000, citric acid monohydrate and acetyltributyl citrate were investigated in terms of plasticization efficiency and preservation of the delayed drug release properties. The aqueous solubility of the plasticizer and its plasticization efficiency impacted the drug release rate from the matrix pellets. The use of water-soluble plasticizers resulted in a loss of gastric protection, whereas low drug release rates in acid were found for pellets containing insoluble plasticizers or no plasticizer, independent of the extent of Eudragit S100 plasticization. The release rate of theophylline in buffer pH 7.4 was faster for pellets that were prepared with efficient plasticizers. The microstructure and solid-state properties of plasticized pellets were further investigated by scanning electron microscopy and powder X-ray diffraction. Pellets prepared with efficient plasticizers (TEC, methylparaben, PEG 8000) exhibited matrices of low porosity, and the drug was homogeneously dispersed in its original polymorphic form. Pellets containing ATBC or citric acid monohydrate had to be extruded at elevated temperature and showed physical instabilities in

Over the last 20 years, there has been increasing focus on the development of novel stem cell based therapies for the treatment of disorders and diseases affecting the enteric nervous system (ENS) of the gastrointestinal tract (so-called enteric neuropathies). Here, the idea is that ENS progenitor/stem cells could be transplanted into the gut wall to replace the damaged or absent neurons and glia of the ENS. This White Paper sets out experts’ views on the commonly used methods and approaches to identify, isolate, purify, expand and optimize ENS stem cells, transplant them into the bowel, and assess transplant success, including restoration of gut function. We also highlight obstacles that must be overcome in order to progress from successful preclinical studies in animal models to ENS stem cell therapies in the clinic. PMID:27059883

According to statistical projections of the World Health Organization, during the period between 1950 and 2025, the group of elderly in Brazil will have increased 15 times. Chronic-degenerative diseases are the illnesses that most affect the elderly population, directly related to the growing demand for Enteral Nutrition Therapy. The objective of this study was to analyze the demographic, epidemiological and nutritional profile of elderly patients assisted at the public hospitals in the Home Enteral Nutrition Therapy Program, of the State Health Department of Distrito Federal. This is a retroprospective, cross-sectional and analytical study, based on primary data, which enrolled 141 elderly patients who were prescribed home enteral nutrition. The collected variables corresponded to age, gender, clinical diagnosis, enteral route and nutritional status at the beginning of Home Enteral Nutrition Therapy. The association between variables was analyzed through the t-Student and chi-square tests, with a significance level of 0.05 and a Confidence Interval (CI) of 95%. There was a higher number of female patients (53.9%) when compared to male (46.1%), average age 75.82 years old for both groups. The most prevalent diseases were cerebro-vascular accident sequels and cancer (42.6% and 22.7% respectively). It was observed a prevalence of malnutrition equal to 69.7%, independent of age and gender. The most used enteral route was the nasal. Though Brazilian policies concerning assistance to the elderly have advanced during the last few years, the need for public policies for nutritional recovery of such patients persists, to promote a better quality of life for them.

Mycophenolate mofetil (MMF) and enteric-coated mycophenolate sodium (EC-MPS) are bioequivalent. However, the effectiveness of MMF may be limited by gastrointestinal (GI) side effects. This study assessed the relationship between the number of medication dosage adjustments and posttransplantation side effects. In a review of 109 kidney transplant patients, 65 initially received MMF and 44 initially received EC-MPS. The incidences of patient-reported GI complications were significantly different: MMF 45.5% vs EC-MPS 35.3% (P = .0194). The proportions of patients requiring dosage adjustment due to GI complications were MMF 5.9% and EC-MPS 2.3% (P < .0001). Patients receiving MMF were more likely to experience GI complications resulting in dosage adjustment (odds ratio = 9.9; P = .0306). The incidences of acute rejection, cytomegalovirus (CMV), and leukopenia resulting in dosage adjustment were not significantly different. Patients receiving MMF required more immunosuppressive medication adjustments, which may complicate care and decrease overall compliance.
Solutions of Clinifeed ISO, Triosorbon, Vivonex Standard (full- and half-strength) and Vivonex HN were experimentally contaminated with two strains each of Staphylococcus aureus, Pseudomonas aeruginosa, Klebsiella aerogenes, Escherichia coli and Enterobacter cloacae at concentrations of 10(2)-10(3) organisms/ml. Samples were incubated at 4, 25 or 37 degrees C and viable counts were made at 0, 4, 8 and 24 h. No increase in numbers of any of the organisms was observed in any of the feeds during 24 h at 4 degrees C. All organisms multiplied rapidly in Clinifeed ISO and in Triosorbon at 25 and 37 degrees C. There was less rapid growth in half-strength Vivonex Standard at 25 degrees C, although at 37 degrees C all strains multiplied rapidly except for the two S. aureus strains, the growth of which was inhibited in half-strength Vivonex Standard at both 25 and 37 degrees C. In full-strength Vivonex Standard at 25 degrees C, only P. aeruginosa showed any increase in numbers during 24 h, whereas P. aeruginosa, K. aerogenes and E. cloacae all multiplied at 37 degrees C. None of the test organisms multiplied in full strength Vivonex HN at any of the temperatures studied. The results of the study show that bacteria survive and may multiply even in feeds with low pH and high osmolarity, and emphasise the importance of strict hygiene during the preparation and handling of all enteral feeds.

Twenty-four patients with severe radiation injury to the small bowel seen over a 4-year period were randomized to four treatment groups: 1) methylprednisolone 80 mg intravenously plus Vivonex-HN, 2 L/day po, 2) methylprednisolone 80 mg intravenously plus total parenteral nutrition, 2.5 L/day, 3) total parenteral nutrition, 2.5 L/day, and 4) Vivonex-HN, 2 L/day po. Patients received nothing by mouth except water in groups II and III, and only Vivonex-HN in groups I and IV. Patients were treated for 8-wk periods. Improvement was gauged by overall nutritional assessment measurements, nitrogen balance data and by radiological and clinical parameters. No significant difference between groups I, II, III, and IV could be found for age, sex, mean radiation dosage, time of onset after radiation therapy, or initial nutritional assessment data. Differences statistically could be found between groups II and III and I and IV regarding nutritional assessment data, nitrogen balance, radiographic and clinical parameters after therapy, with marked improvement noted in groups II and III. We conclude that a treatment regimen consisting of total parenteral nutrition and bowel rest is beneficial in the treatment of radiation enteritis. Methylprednisolone appears to enhance this effect and indeed, may be responsible for a longer lasting response.

Percutaneous drainage is a routinely performed radiologic procedure used in the management of abdominal abscesses. This technique has become the preferred method of treatment for most abdominal and pelvic abscesses, specifically those of enteric origin related to surgical procedures, appendicitis, diverticulitis, and Crohn disease. The well-documented safety and therapeutic efficacy of percutaneous abscess drainage (PAD) lead to the acceptance of this procedure as the primary means of managing abdominal abscesses, obviating the need for surgery in many instances. PAD may provide definitive therapy or may serve as a temporizing measure before delayed surgical treatment. Although PAD was originally reserved for treatment of unilocular, relatively superficial fluid collections, the role of PAD has evolved such that it is now used to manage complex multilocular fluid collections and abscesses that lie deep within the abdomen or pelvis. Although the standard transabdominal approach is preferred, a variety of approaches, including transgastric, transrectal, transvaginal, and transgluteal, may be used. PAD is performed using CT or sonographic guidance.

Background The enzyme in matrix metalloproteinase (MMP)-9 has been suggested to be an important determinant of plaque degradation. While several studies have shown elevated levels in patients with coronary heart disease, results in prospective population based studies evaluating MMP-9 in relation to first time coronary events have been inconclusive. As of today, there are four published studies which have measured MMP-9 in serum and none using plasma. Measures of MMP-9 in serum have been suggested to have more flaws than measures in plasma. Aim To investigate the independent association between plasma levels of MMP-9 and first-time incidence of coronary events in an 8-year follow-up. Material and Methods 428 men and 438 women, aged 45–69 years, free of previous coronary events and stroke at baseline, were followed-up. Adjustments were made for sex, age, socioeconomic position, behavioral and cardiovascular risk factors, chronic disease at baseline, depressive symptoms, interleukin-6 and C-reactive protein. Results 53 events were identified during a risk-time of 6 607 person years. Hazard ratio (HR) for MMP-9 after adjustment for all covariates were HR = 1.44 (1.03 to 2.02, p = 0.033). Overall, the effect of adjustments for other cardiovascular risk factors was low. Conclusion Levels of plasma MMP-9 are independently associated with risk of first-time CHD events, regardless of adjustments. These results are in contrast to previous prospective population-based studies based on MMP-9 in serum. It is essential that more studies look at MMP-9 levels in plasma to further evaluate the association with first coronary events. PMID:26389803

Background Recurrent instability following a first-time anterior traumatic shoulder dislocation may exceed 26%. We systematically reviewed risk factors which predispose this population to events of recurrence. Methods A systematic review of studies published before 1 July 2014. Risk factors which predispose recurrence following a first-time traumatic anterior shoulder dislocation were documented and rates of recurrence were compared. Pooled ORs were analysed using random-effects meta-analysis. Results Ten studies comprising 1324 participants met the criteria for inclusion. Recurrent instability following a first-time traumatic anterior shoulder dislocation was 39%. Increased risk of recurrent instability was reported in people aged 40 years and under (OR=13.46), in men (OR=3.18) and in people with hyperlaxity (OR=2.68). Decreased risk of recurrent instability was reported in people with a greater tuberosity fracture (OR=0.13). The rate of recurrent instability decreased as time from the initial dislocation increased. Other factors such as a bony Bankart lesion, nerve palsy and occupation influenced rates of recurrent instability. Conclusions Sex, age at initial dislocation, time from initial dislocation, hyperlaxity and greater tuberosity fractures were key risk factors in at least two good quality cohort studies resulting in strong evidence as concluded in the GRADE criteria. Although bony Bankart lesions, Hill Sachs lesions, occupation, physiotherapy treatment and nerve palsy were risk factors for recurrent instability, the evidence was weak using the GRADE criteria—these findings relied on poorer quality studies or were inconsistent among studies.

Enteric glia are important components of the enteric nervous system (ENS) and also form an extensive network in the mucosa of the gastrointestinal (GI) tract. Initially regarded as passive support cells, it is now clear that they are actively involved as cellular integrators in the control of motility and epithelial barrier function. Enteric glia form a cellular and molecular bridge between enteric nerves, enteroendocrine cells, immune cells, and epithelial cells, depending on their location. This Review highlights the role of enteric glia in GI motility disorders and in barrier and defense functions of the gut, notably in states of inflammation. It also discusses the involvement of enteric glia in neurological diseases that involve the GI tract. PMID:25689252

For the first time in 16 years, a food-borne outbreak of typhoid fever due to Salmonella enterica serotype Typhi was reported in Japan. Seven patients consumed food in an Indian buffet at a restaurant in the center of Tokyo, while one was a Nepali chef in the restaurant, an asymptomatic carrier and the implicated source of this outbreak. The multiple-locus variable-number tandem repeat analysis showed 100% consistency in the genomic sequence for five of the eight cases. PMID:26621565
Abstract Due to their bluish basidiocarps the Postia caesia (syn. Oligoporus caesius) complex forms a distinctive morphological group within the polypore genus Postia Fr., 1874. Five species of this group occur in Europe: Postia alni Niemelä & Vampola, Postia caesia (Schrad.) P. Karst., Postia luteocaesia (A. David) Jülich, Postia mediterraneocaesia M. Pierre & B. Rivoire and Postia subcaesia (A. David) Jülich. In this study Postia alni is reported for the first time from Hungary. The dichotomous key of the species of the European Postia caesia complex was prepared as well. PMID:24855437
The use of enteral feeding tubes, such as nasogastric and gastrostomy tubes, to support a patient's nutritional intake is generally considered to be safe and effective. However, recent alerts and recommendations from the National Patient Safety Agency (NPSA) regarding enteral feeding have led health professionals to review their practice and guidelines. This article explores safe practice in enteral tube feeding in the light of three NPSA alerts: Promoting safer measurement and administration of liquid medicines via oral and other enteral routes (2007), Early detection of complications after gastrostomy (2010) and Reducing the harm caused by misplaced nasogastric tubes in adults and children (2011).

Home enteral nutrition is the administration of enteral formulae into the digestive tract using a tube, with the objective of preventing or correcting malnutrition patients who are seen at home. Home enteral nutrition is a type of nutritional support that is growing, that improves the nutritional status of the patient with a lower cost and with a greater quality of life of the family unit than enteral nutrition in the hospital. The prevalence is clearly increasing although the data of the national registers of patients with at home enteral nutrition are under estimated. Patients who are candidates for home enteral nutrition can be all those with an indication for enteral nutrition and whose underlying disease is stabilized or does not require all the technical means of the hospital in a permanent and essential manner. Neoplasias and neurological diseases are those that benefit most from at home enteral nutrition and in all registries each group varies between 30 and 40%. All access routes and all enteral nutrition formulae can be used in patients with home enteral nutrition. The use of percutaneous endoscopic gastrostomies is ever more recommended in patients who need at home enteral nutrition for a period longer than 4 weeks. Since the publication of the Ministerial Order of June 2nd 1998, home enteral nutrition is considered a health care service that can be covered by the Social Security. This order lists a series of disease that are likely to be treated with at home enteral nutrition (in our opinion the list is not complete but it is likely to be changed in the future by an Assessing Committee), and it presents some basic norms that all patients must comply with, regardless of the autonomous community in which they live. Before beginning at home enteral nutrition the training of the patient and/or the family with regard to the management of at home enteral nutrition is essential. The existence of qualified personnel with experience in this nutritional support

Enteral feeding is a long established practice across pediatric and adult populations, to enhance nutritional intake and prevent malnutrition. Despite recognition of the importance of nutrition within the modern health agenda, evaluation of the efficacy of how such feeds are delivered is more limited. The accuracy, safety, and consistency with which enteral feed pump systems dispense nutritional formulae are important determinants of their use and acceptability. Enteral feed pump safety has received increased interest in recent years as enteral pumps are used across hospital and home settings. Four areas of enteral feed pump safety have emerged: the consistent and accurate delivery of formula; the minimization of errors associated with tube misconnection; the impact of continuous feed delivery itself (via an enteral feed pump); and the chemical composition of the casing used in enteral feed pump manufacture. The daily use of pumps in delivery of enteral feeds in a home setting predominantly falls to the hands of parents and caregivers. Their understanding of the use and function of their pump is necessary to ensure appropriate, safe, and accurate delivery of enteral nutrition; their experience with this is important in informing clinicians and manufacturers of the emerging needs and requirements of this diverse patient population. The review highlights current practice and areas of concern and establishes our current knowledge in this field. PMID:25170284

The number of radiotherapy in the treatment of malignant diseases is increasing worldwide. During the radiotherapy of tumors in the minor pelvis and abdomen intestinal inflammation of different degree may occur even if special attention is paid. Irradiation to the minor pelvis causes in half of the cases radiation induced acute enteritis, whereas in 25% chronic enteritis and colitis will develop. Chronic enteritis following radiotherapy raises a number of diagnostic and therapeutic problems that can be solved only with cooperation of different specialties. Authors present a short review regarding therapeutical options of radiation induced enteritis.

Syndromic diarrhea/Tricho-hepato-enteric syndrome (SD/THE) is a rare and severe bowel disorder caused by mutation in SKIV2L or in TTC37, 2 genes encoding subunits of the putative human SKI complex. The estimated prevalence is 1/1,000,000 births and the transmission is autosomal recessive. The classical form is characterized by 5 clinical signs: intractable diarrhea of infancy beginning in the first month of life, usually leading to failure to thrive and requiring parenteral nutrition; facial dysmorphism characterised by prominent forehead and cheeks, broad nasal root and hypertelorism; hair abnormalities described as woolly and easily removable; immune disorders resulting from defective antibody production; intrauterine growth restriction. The aetiology is a defect in TTC37, a TPR containing protein, or in the RNA helicase SKIV2L, both constituting the putative human ski complex. The ski complex is a heterotetrameric cofactor of the cytoplasmic RNA exosome which ensures aberrants mRNAs decay. The diagnosis SD/THE is initially based on clinical findings and confirmed by direct sequencing of TTC37 and SKIV2L. Differential diagnosis with the other causes of intractable diarrhea is easily performed by pathologic investigations. During their clinical course, most of the children require parenteral nutrition and often immunoglobulin supplementation. With time, some of them can be weaned off parenteral nutrition and immunoglobulin supplementation. The prognosis depends on the management and is largely related to the occurrence of parenteral nutrition complications or infections. Even with optimal management, most of the children seem to experience failure to thrive and final short stature. Mild mental retardation is observed in half of the cases.

From a historical perspective, the study of both the biochemistry and the genetics of lipopolysaccharide (LPS) synthesis began with the enteric bacteria. These organisms have again come to the forefront as the blocks of genes involved in LPS synthesis have been sequenced and analyzed. A number of new and unanticipated genes were found in these clusters, indicating a complexity of the biochemical pathways which was not predicted from the older studies. One of the most dramatic areas of LPS research has been the elucidation of the lipid A biosynthetic pathway. Four of the genes in this pathway have now been identified and sequenced, and three of them are located in a complex operon which also contains genes involved in DNA and phospholipid synthesis. The rfa gene cluster, which contains many of the genes for LPS core synthesis, includes at least 17 genes. One of the remarkable findings in this cluster is a group of several genes which appear to be involved in the synthesis of alternate rough core species which are modified so that they cannot be acceptors for O-specific polysaccharides. The rfb gene clusters which encode O-antigen synthesis have been sequenced from a number of serotypes and exhibit the genetic polymorphism anticipated on the basis of the chemical complexity of the O antigens. These clusters appear to have originated by the exchange of blocks of genes among ancestral organisms. Among the large number of LPS genes which have now been sequenced from these rfa and rfb clusters, there are none which encode proteins that appear to be secreted across the cytoplasmic membrane and surprisingly few which encode integral membrane proteins or proteins with extensive hydrophobic domains. These data, together with sequence comparison and complementation experiments across strain and species lines, suggest that the LPS biosynthetic enzymes may be organized into clusters on the inner surface of the cytoplasmic membrane which are organized around a few key membrane

Background Diet and environment impact the composition of mammalian intestinal microbiota; dietary or health disturbances trigger alterations in intestinal microbiota composition and render the host susceptible to enteric pathogens. To date no long term monitoring data exist on the fecal microbiota and pathogen load of carnivores either in natural environments or in captivity. This study investigates fecal microbiota composition and the presence of pathogenic Escherichia coli and toxigenic clostridia in wild and captive grizzly bears (Ursus arctos) and relates these to food resources consumed by bears. Methodology/Principal Findings Feces were obtained from animals of two wild populations and from two captive animals during an active bear season. Wild animals consumed a diverse diet composed of plant material, animal prey and insects. Captive animals were fed a regular granulated diet with a supplement of fruits and vegetables. Bacterial populations were analyzed using quantitative PCR. Fecal microbiota composition fluctuated in wild and in captive animals. The abundance of Clostridium clusters I and XI, and of C. perfringens correlated to regular diet protein intake. Enteroaggregative E. coli were consistently present in all populations. The C. sordellii phospholipase C was identified in three samples of wild animals and for the first time in Ursids. Conclusion This is the first longitudinal study monitoring the fecal microbiota of wild carnivores and comparing it to that of captive individuals of the same species. Location and diet affected fecal bacterial populations as well as the presence of enteric pathogens. PMID:22194798

Neuroimmune interactions are an integral part of gut physiology and involved in the pathogenesis of inflammatory and functional bowel disorders. Mast cells and their mediators are important conveyors in the communication from the innate enteric immune system to the enteric nervous system (ENS). However, it is not known whether a mediator cocktail released from activated human mast cells affects neural activity in the ENS. We used the Multi-Site Optical Recording Technique to image single cell activity in guinea-pig and human ENS after application of a mast cell mediator cocktail (MCMC) that was released from isolated human intestinal mucosa mast cells stimulated by IgE-receptor cross-linking. Local application of MCMC onto individual ganglia evoked an excitatory response consisting of action potential discharge. This excitatory response occurred in 31%, 38% or 11% neurons of guinea-pig submucous plexus, human submucous plexus, or guinea-pig myenteric plexus, respectively. Compound action potentials from nerve fibres or fast excitatory synaptic inputs were not affected by MCMC. This study demonstrates immunoneural signalling in the human gut and revealed for the first time that an MCMC released from stimulated human intestinal mast cells induces excitatory actions in the human and guinea-pig ENS.

ABSTRACT To establish a replicative niche during its infectious cycle between the intestinal lumen and tissue, the enteric pathogen Salmonella enterica serovar Typhimurium requires numerous virulence genes, including genes for two type III secretion systems (T3SS) and their cognate effectors. To better understand the host-pathogen relationship, including early infection dynamics and induction kinetics of the bacterial virulence program in the context of a natural host, we monitored the subcellular localization and temporal expression of T3SS-1 and T3SS-2 using fluorescent single-cell reporters in a bovine, ligated ileal loop model of infection. We observed that the majority of bacteria at 2 h postinfection are flagellated, express T3SS-1 but not T3SS-2, and are associated with the epithelium or with extruding enterocytes. In epithelial cells, S. Typhimurium cells were surrounded by intact vacuolar membranes or present within membrane-compromised vacuoles that typically contained numerous vesicular structures. By 8 h postinfection, T3SS-2-expressing bacteria were detected in the lamina propria and in the underlying mucosa, while T3SS-1-expressing bacteria were in the lumen. Our work identifies for the first time the temporal and spatial regulation of T3SS-1 and -2 expression during an enteric infection in a natural host and provides further support for the concept of cytosolic S. Typhimurium in extruding epithelium as a mechanism for reseeding the lumen. PMID:24496791

First-time blood donors are essential to the US donor pool, providing nearly a third of all donations. Unfortunately, there are a wide variety of obstacles to repeat donation and new donors are extremely difficult to retain. Because each donor experiences a unique set of deterrents, we developed a post-donation interview based on motivational interview principles in order to flexibly address individual barriers. The primary aim of this randomized clinical trial is to examine retention of first-time, group O blood donors who are randomly assigned to receive either a telephone-delivered interview with motivational and action planning components or a standard-of-care control call approximately six weeks after their donation. Measures of donation attitude, perceived behavioral control, intention, and motivational autonomy will be measured before and after the telephone contact using online surveys, and donation attempts will be tracked for one year using blood center donor databases. We hypothesize that, compared to controls, donors who receive the telephone interview will be more likely to make a donation attempt over the following year. In addition, we will examine possible mechanisms of action of the interview using key predictors of donation behavior as described by Self Determination Theory (i.e., motivational autonomy) and the Theory of Planned Behavior (i.e., attitude, perceived behavioral control, and intention). Results of this intervention may help to support a novel strategy to enhance retention of selected blood donors in an effort to better meet the nation's blood supply needs.

Students in undergrad research internships go on to grad school at rates of 50-75% (Lopatto, 2007;Russell, 2005). NSF studied its undergrad program and found that 74% of physics interns (67% for engineering) go to grad school. PPPL undergrad interns were tracked for 10 years. Only 3% of physics PhD candidates are studying plasma physics, but 23% of our alumni that entered grad school did so in plasma. AIP reports that 60% of physics majors go to grad school (AIP, 2012), but 95% of PPPL interns have gone on to grad schools. Several programs track enrollment in grad school. AIP compiles statistics of undergrads who enter grad school and PhD students who work in the field. There has been no study of interns that follows the path from undergrad to grad school and then on to employment. Our tracking shows that most not only complete their advanced degrees but also stay in STEM fields following their academic careers. 88% of them become part of the STEM workforce, higher than the 82% of all physics PhDs employed in physics after obtaining their degree (AIP, 2014). PPPL puts more students in grad school in physics, and specifically plasma physics, and a higher percentage of those grad students stay in the STEM workforce.

Human enteric viruses are among the main causative agents of shellfish-associated outbreaks. In this study, the kinetics of viral bioaccumulation in live oysters and the heat stabilities of the predominant enteric viruses were determined both in tissue culture and in oyster tissues. A human norovirus (HuNoV) GII.4 strain, HuNoV surrogates (murine norovirus [MNV-1], Tulane virus [TV]), hepatitis A virus (HAV), and human rotavirus (RV) bioaccumulated to high titers within oyster tissues, with different patterns of bioaccumulation for the different viruses. We tested the thermal stability of each virus at 62, 72, and 80°C in culture medium. The viruses can be ranked from the most heat resistant to the least stable as follows: HAV, RV, TV, MNV-1. In addition, we found that oyster tissues provided protection to the viruses during heat treatment. To decipher the mechanism underlying viral inactivation by heat, purified TV was treated at 80°C for increasing time intervals. It was found that the integrity of the viral capsid was disrupted, whereas viral genomic RNA remained intact. Interestingly, heat treatment leading to complete loss of TV infectivity was not sufficient to completely disrupt the receptor binding activity of TV, as determined by the porcine gastric mucin–magnetic bead binding assay. Similarly, HuNoV virus-like particles (VLPs) and a HuNoV GII.4 strain retained some receptor binding ability following heat treatment. Although foodborne viruses have variable heat stability, 80°C for >6 min was sufficient to completely inactivate enteric viruses in oysters, with the exception of HAV. PMID:26826225

IgG of type 1 anti-neuronal nuclear antibody (ANNA-1, anti-Hu) specificity is a serological marker of paraneoplastic neurological autoimmunity (including enteric/autonomic) usually related to small-cell lung carcinoma. We show here that IgG isolated from such sera and also affinity-purified anti-HuD label enteric neurons and cause an immediate spike discharge in enteric and visceral sensory neurons. Both labelling and activation of enteric neurons was prevented by preincubation with the HuD antigen. Activation of enteric neurons was inhibited by the nicotinic receptor antagonists hexamethonium and dihydro-β-erythroidine and reduced by the P2X antagonist pyridoxal phosphate-6-azo (benzene-2,4-disulfonic acid (PPADS) but not by the 5-HT3 antagonist tropisetron or the N-type Ca-channel blocker ω-Conotoxin GVIA. Ca++ imaging experiments confirmed activation of enteric neurons but not enteric glia. These findings demonstrate a direct excitatory action of ANNA-1, in particular anti-HuD, on visceral sensory and enteric neurons, which involves nicotinic and P2X receptors. The results provide evidence for a novel link between nerve activation and symptom generation in patients with antibody-mediated gut dysfunction. PMID:27905561

We examined esophageal cancer patients who received enteral nutrition (EN) to evaluate the validity of early EN compared to delayed EN, and to determine the appropriate time to start EN. A total of 208 esophagectomy patients who received EN postoperatively were divided into three groups (Group 1, 2 and 3) based on whether they received EN within 48 h, 48 h-72 h or more than 72 h, respectively. The postoperative complications, length of hospital stay (LOH), days for first fecal passage, cost of hospitalization, and the difference in serum albumin values between pre-operation and post-operation were all recorded. The statistical analyses were performed using the t-test, the Mann-Whitney U test and the chi square test. Statistical significance was defined as p < 0.05. Group 1 had the lowest thoracic drainage volume, the earliest first fecal passage, and the lowest LOH and hospitalization expenses of the three groups. The incidence of pneumonia was by far the highest in Group 3 (p = 0.019). Finally, all the postoperative outcomes of nutritional conditions were the worst by a significant margin in Group 3. It is therefore safe and valid to start early enteral nutrition within 48 h for postoperative esophageal cancer patients.

Out of the 20 channels in the channel and collateral system, only 5 enter the brain, with unclear circulation pathway in the brain. Electrophysiologic and imaging studies indicate that the signal induced by acupuncture at acupoints can enter the brain no matter whether the channel connecting the acupoint enters the brain. Therefore, the authors put forward the hypothesis of "all the 12 channels enter the brain", i.e., the hypothesis of "channels and collaterals in brain". In the theory system of channels, less channels enter the brain with unclear circulation pathway. This possibly is related with that sensation is main way for descovery of channels. In future, we should adopt modern scientific and technical ways and strengthen the study on circulation of channels in the brain, so as to perfect the channel theory.

In Jordan, there is a gap in literature regarding nurses' practices of enteral nutrition. Thus, the purpose of this study was to assess nurses' practices regarding enteral nutrition of critically ill adult patients. A descriptive, cross-sectional design was used to collect data through self-reported questionnaires and descriptive analyses were used to display the results of the study. The results revealed that some aspects of enteral nutrition practices were consistent with the current best evidences such as initiation time of enteral nutrition and backrest elevation. On the contrary, some aspects showed variations and inconsistency with current best evidences such as the amount of high gastric residual volume and its management. Nurses' practices regarding enteral nutrition were not consistent with international guidelines. This inconsistency can predispose patients to underfeeding. Enhancement of research utilization is highly recommended as well as establishing evidence-based guidelines.

Oral and enteral nutrition affects both the anatomical and physiological integrity of the gastrointestinal tract. It downregulates systemic immune response, reduces overall oxidative stress and limits systemic inflammatory responses. It reduces bacterial translocation, limits pathogenic bacteria in the intestines and enables the production of short-chain fatty acids in the colon. Therefore, it is the most physiologic way of providing nutritional support in all patients. The enteral formulas are available as polymeric, semi-elemental and elemental diets. The beneficial effects on the gastrointestinal tract and systemic organs of 'early' enteral nutrition depend on the timing, dose, location and different modalities of enteral delivery. Being familiar with the basic tenets of providing enteral nutrition - the 'Who, Why, When, Where and What' - will result in safe nutritional interventions and achieve a positive clinical outcome.

The incidence of upper gastrointestinal (GI) bleeding in mechanically ventilated ICU patients receiving enteral alimentation was reviewed and compared to bleeding occurring in ventilated patients receiving prophylactic antacids or cimetidine. Of 250 patients admitted to our ICU during a 1-yr time period, 43 ventilated patients were studied. Patients in each group were comparable with respect to age, respiratory diagnosis, number of GI hemorrhage risk factors, and number of ventilator, ICU, and hospital days. Twenty-one patients had evidence of GI bleeding. Fourteen of 20 patients receiving antacids and 7 of 9 patients receiving cimetidine had evidence of GI bleeding. No bleeding occurred in 14 patients receiving enteral alimentation. Complications of enteral alimentation were few and none required discontinuation of enteral alimentation. Our preliminary data suggest the role of enteral alimentation in critically ill patients may include not only protection against malnutrition but also protection against GI bleeding.

In insects, like in other animals, experience-based modulation of preference, a form of phenotypic plasticity, is common in heterogeneous environments. However, the role of multiple fitness-relevant experiences on insect preference remains largely unexplored. For the multivoltine polyphagous moth Spodoptera littoralis we investigated effects of larval and adult experiences on subsequent reproductive behaviours. We demonstrate, for the first time in male and female insects, that mating experience on a plant modulates plant preference in subsequent reproductive behaviours, whereas exposure to the plant alone or plant together with sex pheromone does not affect this preference. When including larval feeding experiences, we found that both larval rearing and adult mating experiences modulate host plant preference. These findings represent the first evidence that host plant preferences in polyphagous insects are determined by a combination of innate preferences modulated by sensory feedback triggered by multiple rewarding experiences throughout their lifetime.

Two species, E. lanceolatum Likhitrakarn et al., 2014 and E. anchoriforme Likhitrakarn et al., 2014, were previously known only from the western part of Laos, thus being new to the fauna of Vietnam. One more species, Sundanina fedorenkoi Golovatch, 2016, very recently described from Dak Lak Province, southern Vietnam, is formally transferred to Enghoffosoma, comb. nov., based both on a strict topotype and a sample from Lam Dong Province, southern Vietnam. Three other species are described as new: E. triangulare sp. nov., E. retrorsum sp. nov. and E. digitatum sp. nov. A key to all six species of Enghoffosoma currently known to occur in Vietnam is provided.

Objective: Although there is an established link between parenting stress, postnatal depression, and anxiety, no study has yet investigated this link in first-time parental couples. The specific aims of this study were 1) to investigate whether there were any differences between first-time fathers’ and mothers’ postnatal parenting stress, anxiety, and depression symptoms and to see their evolution between three and 6 months after their child’s birth; and 2) to explore how each parent’s parenting stress and anxiety levels and the anxiety levels and depressive symptoms of their partners contributed to parental postnatal depression. Method: The sample included 362 parents (181 couples; mothers’ MAge = 35.03, SD = 4.7; fathers’ MAge = 37.9, SD = 5.6) of healthy babies. At three (T1) and 6 months (T2) postpartum, both parents filled out, in a counterbalanced order, the Parenting Stress Index-Short Form, the Edinburgh Postnatal Depression Scale, and the State-Trait Anxiety Inventory. Results: The analyses showed that compared to fathers, mothers reported higher scores on postpartum anxiety, depression, and parenting stress. The scores for all measures for both mothers and fathers decreased from T1 to T2. However, a path analysis suggested that the persistence of both maternal and paternal postnatal depression was directly influenced by the parent’s own levels of anxiety and parenting stress and by the presence of depression in his/her partner. Discussion: This study highlights the relevant impact and effects of both maternal and paternal stress, anxiety, and depression symptoms during the transition to parenthood. Therefore, to provide efficacious, targeted, early interventions, perinatal screening should be directed at both parents. PMID:27445906

Duck virus enteritis, also known as duck plague, is a viral infection of ducks caused by duck enteritis virus (DEV). The control of the disease is mainly done by vaccination with chicken embryo adapted live virus that is known to be poorly immunogenic and elicits only partial protection. Further, the embryo propagated vaccine virus pose a threat of harboring other infectious agents. Seeing these limitations, the present study reports for the first time regarding propagation and adaptation of a virulent Indian isolate of duck enteritis virus in Vero cell line. In this study isolation of an outbreak virus from Kerala state was done in chicken embryo fibroblast cell culture (CEF). Then adapted the DEV isolate in the Vero cell line. The characteristic cytopathic effects (CPE) of clumping and fusion of Vero cells were observed starting from the 7th passage onwards. The presence of the virus and its multiplication in Vero cells was confirmed by detection of viral specific DNA and antigen by using polymerase chain reaction (PCR) and indirect immuno fluorescent assay (IIFA), respectively. PCR detection of DEV using self designed primers for US4 (gD) and UL30 (DNA Polymerase) gene has been reported for the in the present study. The kinetics of DEV in Vero cells revealed a maximum infectivity titer of 10(5.6) TCID 50/ml after 48hr of viral infection. Compared to chicken embryo adapted DVE vaccine virus, the Vero cell culture system is free from other infectious agents. So it will be a good candidate for cultivation and propagation of duck enteritis virus vaccine strain. Further research studies are suggested to explore the feasibility of utilizing this Vero cell culture adapted DEV isolate for developing an attenuated vaccine virus against duck virus enteritis.

This short review describes the conceptual development in the search for the enteric neural circuits with the initial identifications of the classes of enteric neurons on the bases of their morphology, neurochemistry, biophysical properties, projections and connectivity. The discovery of the presence of multiple neurochemicals in the same nerve cells in specific combinations led to the concept of "chemical coding" and of "plurichemical transmission". The proposal that enteric reflexes are largely responsible for the propulsion of contents led to investigations of polarised reflex pathways and how these may be activated to generate the coordinated propulsive behaviour of the intestine. The research over the past decades attempted to integrate information of chemical neuroanatomy with functional studies, with the development of methods combining anatomical, functional and pharmacological techniques. This multidisciplinary strategy led to a full accounting of all functional classes of enteric neurons in the guinea-pig, and advanced wiring diagrams of the enteric neural circuits have been proposed. In parallel, investigations of the actual behaviour of the intestine during physiological motor activity have advanced with the development of spatio-temporal analysis from video recordings. The relation between neural pathways, their activities and the generation of patterns of motor activity remain largely unexplained. The enteric neural circuits appear not set in rigid programs but respond to different physico-chemical contents in an adaptable way (neuromechanical hypothesis). The generation of the complex repertoire of motor patterns results from the interplay of myogenic and neuromechanical mechanisms with spontaneous generation of migratory motor activity by enteric circuits.

Ulcerative colitis (UC) is a leading form of inflammatory bowel disease that involves chronic relapsing or progressive inflammation. As a significant proportion of UC patients treated with conventional therapies do not achieve remission, there is a pressing need for the development of more effective therapies. The human gut contains a large, diverse, and dynamic population of microorganisms, collectively referred to as the enteric microbiota. There is a symbiotic relationship between the human host and the enteric microbiota, which provides nutrition, protection against pathogenic organisms, and promotes immune homeostasis. An imbalance of the normal enteric microbiota composition (termed dysbiosis) underlies the pathogenesis of UC. A reduction of enteric microbiota diversity has been observed in UC patients, mainly affecting the butyrate-producing bacteria, such as Faecalibacterium prausnitzii, which can repress pro-inflammatory cytokines. Many studies have shown that enteric microbiota plays an important role in anti-inflammatory and immunoregulatory activities, which can benefit UC patients. Therefore, manipulation of the dysbiosis is an attractive approach for UC therapy. Various therapies targeting a restoration of the enteric microbiota have shown efficacy in treating patients with active and chronic forms of UC. Such therapies include fecal microbiota transplantation, probiotics, prebiotics, antibiotics, helminth therapy, and dietary polyphenols, all of which can alter the abundance and composition of the enteric microbiota. Although there have been many large, randomized controlled clinical trials assessing these treatments, the effectiveness and safety of these bacteria-driven therapies need further evaluation. This review focuses on the important role that the enteric microbiota plays in maintaining intestinal homeostasis and discusses new therapeutic strategies targeting the enteric microbiota for UC.

The intrinsic neurons of the gut, enteric neurons, have an essential role in gastrointestinal functions. The enteric nervous system is plastic and continues to undergo changes throughout life, as the gut grows and responds to dietary and other environmental changes. Detailed analysis of changes in the ENS during ageing suggests that enteric neurons are more vulnerable to age-related degeneration and cell death than neurons in other parts of the nervous system, although there is considerable variation in the extent and time course of age-related enteric neuronal loss reported in different studies. Specific neuronal subpopulations, particularly cholinergic myenteric neurons, may be more vulnerable than others to age-associated loss or damage. Enteric degeneration and other age-related neuronal changes may contribute to gastrointestinal dysfunction that is common in the elderly population. Evidence suggests that caloric restriction protects against age-associated loss of enteric neurons, but recent advances in the understanding of the effects of the microbiota and the complex interactions between enteric ganglion cells, mucosal immune system and intestinal epithelium indicate that other factors may well influence ageing of enteric neurons. Much remains to be understood about the mechanisms of neuronal loss and damage in the gut, although there is evidence that reactive oxygen species, neurotrophic factor dysregulation and/or activation of a senescence associated phenotype may be involved. To date, there is no evidence for ongoing neurogenesis that might replace dying neurons in the ageing gut, although small local sites of neurogenesis would be difficult to detect. Finally, despite the considerable evidence for enteric neurodegeneration during ageing, and evidence for some physiological changes in animal models, the ageing gut appears to maintain its function remarkably well in animals that exhibit major neuronal loss, indicating that the ENS has considerable
'Dissertations into Practice' is a new regular feature in the Health Information and Libraries Journal, which aims to encourage students to write for publication. The idea is that students will write an extended abstract of their health-related dissertations, outlining the methods used and commenting on the implications for practice. Co-written with their dissertation or workplace supervisor, this feature will provide a safe environment for students to see their writing in print, possibly for the first time, while ensuring that invaluable research reaches a wider audience than might otherwise be the case.

In patients unable to tolerate oral intake, multiple options of nutrient delivery are available to the clinician. Administration of enteral nutrition (EN) has long been considered the standard of care for nutrition support among patients unable to meet energy and protein requirements orally. Healthcare practitioners must make careful decisions related to ordering, administering, and monitoring EN therapy. In the hospital setting, the registered dietitian is a key resource in enteral formula selection and method of administration, monitoring for and troubleshooting EN-related complications, and transitioning to oral feeding. The hospital setting also presents many unique challenges in providing optimal nutrition to the enterally fed patient.

Enteral feeding is considered a widespread, well-accepted means of delivering nutrition to adults and children who are unable to consume food by mouth or who need support in maintaining adequate nutrition for a variety of reasons, including acute and chronic disease states. Delivery of enteral feeding to nutritionally deprived patients may be achieved by several means. In this article, the indications and insertion of enteral access in children will be reviewed. In addition, common complications and management of problems will be discussed.

The purpose of this research was to investigate the effectiveness of Frayer Model and the Hierarchical Organizer as a literacy strategy to improve ninth grade students' science vocabulary and comprehension of non-fictions text in Environmental Science course. The study implemented a sequential explanatory methodology design that included quantitative and qualitative instruments. The research sample consisted of one hundred and two (102) high school environmental science students entering the ninth grade for the first time. The two treatment groups each consisted of thirty-five (35) students, and the control group consisted of 32 students. Treatment group one used the Frayer Model; treatment group two used Hierarchical Organizer and the control group used the traditional teaching methods without the use of a graph organizer. The investigator taught both treatment groups and the control group to ensure reliability. The two treatment groups were taught using graphic organizers as the main lesson plan tool and the control group was taught using guided notes lecture with PowerPoint. A pretest and post-test were administered to each student. Student test scores were evaluated to determine whether knowledge gains differed between the treatment groups and the control group. It was found that the use of graphic organizer instruction was significantly better for student achievement when compared to the use of PowerPoint instruction and that there was much more interaction between student and teacher during the graphic organizer lessons. The delivery of the lesson by the use of graphic organizers seemed to promote more success than the use of the PowerPoint and lecture.

OBJECTIVE Common surgical treatments for trigeminal neuralgia (TN) include microvascular decompression (MVD), stereotactic radiosurgery (SRS), and radiofrequency ablation (RFA). Although the efficacy of each procedure has been described, few studies have directly compared these treatment modalities on pain control for TN. Using a large prospective longitudinal database, the authors aimed to 1) directly compare long-term pain control rates for first-time surgical treatments for idiopathic TN, and 2) identify predictors of pain control. METHODS The authors reviewed a prospectively collected database for all patients who underwent treatment for TN between 1997 and 2014 at the University of California, San Francisco. Standardized collection of data on preoperative clinical characteristics, surgical procedure, and postoperative outcomes was performed. Data analyses were limited to those patients who received a first-time procedure for treatment of idiopathic TN with > 1 year of follow-up. RESULTS Of 764 surgical procedures performed at the University of California, San Francisco, for TN (364 SRS, 316 MVD, and 84 RFA), 340 patients underwent first-time treatment for idiopathic TN (164 MVD, 168 SRS, and 8 RFA) and had > 1 year of follow-up. The analysis was restricted to patients who underwent MVD or SRS. Patients who received MVD were younger than those who underwent SRS (median age 63 vs 72 years, respectively; p < 0.001). The mean follow-up was 59 ± 35 months for MVD and 59 ± 45 months for SRS. Approximately 38% of patients who underwent MVD or SRS had > 5 years of follow-up (60 of 164 and 64 of 168 patients, respectively). Immediate or short-term (< 3 months) postoperative pain-free rates (Barrow Neurological Institute Pain Intensity score of I) were 96% for MVD and 75% for SRS. Percentages of patients with Barrow Neurological Institute Pain Intensity score of I at 1, 5, and 10 years after MVD were 83%, 61%, and 44%, and the corresponding percentages after SRS were

The aim of the study was to investigate the effect of microbial immune enteral nutrition by microecopharmaceutics and deep sea fish oil and glutamine and Peptisorb on the patients with acute radiation enteritis in bowel function and immune status. From June 2010 to January 2013, 46 acute radiation enteritis patients in Liaocheng People's Hospital were randomized into the microbial immune enteral nutrition group and the control group: 24 patients in treatment group and 22 patients in control group. The immune microbial nutrition was given to the study group, but not to the control group. The concentration of serum albumin and prealbumin and the number of CD3 (+) T cell, CD4 (+) T cell, CD8 (+) T cell, CD4 (+)/CD8 (+) and natural killer cell of the two groups were detected on the 1, 7 and 14 days after treatment. The arm muscle circumference and triceps skinfold thickness (TSF) were recorded, and the tolerance of the two groups for enteral nutrition and intestinal symptoms was collected and then comparing the two indicators and get results. The tolerance of microbial immune enteral nutrition group about abdominal pain, bloating and diarrhea was better than the control group (P values were 0.018, 0.04 and 0.008 after 7 days; P values were 0.018, 0.015 and 0.002 after 14 days); and the cellular immune parameters were better than the control group((△) P = 0.008,([Symbol: see text]) P = 0.039, (☆) P = 0.032); No difference was found in nutrition indicators. To the patients with acute radiation enteritis, microbial immune enteral nutrition could improve the patient's immune status, and the tolerance of enteral nutrition could be better for the bowel function and the patients' rehabilitation.

Nutritional management by using enteral feeding method of nutrition is required for patients of gastroenterological disease with functional disorder in digestion-absorption, and for cases where the patients have difficulty in taking food orally. There are many cases where enteral nutrition pumps are used for administration of nutritious medicines. Approximately 150 enteral nutrition pumps (including house use and home rental) have currently been utilized at our facility. The department of ME Center takes care of enteral nutrition pumps for maintenance and control. On the other hand, we needed to conduct a study for a new pump in replacing Frenta System IV due to the pump was no longer available. At this presentation, we are introducing a new pump manufactured by Fresenius as a replacement of the Frenta System IV. In the meantime, we would like to report a comparison examination of the pump based on its functionality, performance and user friendliness from the view from a clinical technologist as well.

Abstract This study evaluates serum gastrin concentrations in dogs with chronic lymphocytic-plasmacytic enteritis, as well as its possible relationship with the severity of lesions present in the stomach. To achieve this aim, 5 dogs without gastrointestinal disease and 15 dogs with chronic lymphocytic-plasmacytic enteritis were included. Serum gastrin concentrations were significantly increased in dogs with chronic lymphocytic-plasmacytic enteritis compared with those in dogs without gastrointestinal disease. Also, there was a positive correlation between the severity of the gastric lesion and the serum gastrin concentration. Our findings indicate the possibility that gastrin plays a role in the etiology of an accompanying chronic antral gastritis in canine chronic lymphocytic-plasmacytic enteritis. PMID:16152719

SUMMARY Intestinal peristalsis is a dynamic physiologic process influenced by dietary and microbial changes. It is tightly regulated by complex cellular interactions; however, our understanding of these controls is incomplete. A distinct population of macrophages is distributed in the intestinal muscularis externa. We demonstrate that in the steady state muscularis macrophages regulate peristaltic activity of the colon. They change the pattern of smooth muscle contractions by secreting bone morphogenetic protein 2 (BMP2), which activates BMP receptor (BMPR) expressed by enteric neurons. Enteric neurons, in turn, secrete colony stimulatory factor 1 (CSF1), a growth factor required for macrophage development. Finally, stimuli from microbial commensals regulate BMP2 expression by macrophages and CSF1 expression by enteric neurons. Our findings identify a plastic, microbiota-driven, crosstalk between muscularis macrophages and enteric neurons, which controls gastrointestinal motility. PMID:25036630

Human enteric pathogenic viruses can enter the environment through discharge of waste materials from infected persons, and be transmitted back to susceptible persons to continue the cycle of disease. Contamination of food with viruses may also promote disease outbreaks. A number of studies have investigated the survival characteristics of several enteric viruses in various environments and foodstuffs, to help explain the transmissibility of these pathogens. This review deals with published work on enteric virus survival on fomites, and in waters, soil, and foods; the results of these studies have illustrated the robust survival of viruses in these environments. Much information is lacking, however, especially for foodstuffs and soils, and no detailed information is available concerning the survival of noroviruses, the most significant foodborne type.

The two-hour Rapid SST strip (DMS Laboratories, Inc.) was compared with our standard screening system (triple sugar iron agar, lysine iron agar, and urea) for enteric pathogens. We tested 50 stock cultures of enteric pathogens and 213 stool cultures received in the Barnes Hospital Clinical Microbiology Laboratory over a two-month period. All enteric pathogens from the stock cultures and clinical specimens were identified correctly with the Rapid SST system. More false-positive reactions were observed with the Rapid SST system (34%) than with the conventional system (23%). However, the costs associated with using both systems were equivalent and the test results were available one day faster with the Rapid SST system. Thus, the Rapid SST is a rapid, accurate, and cost-effective method for screening stool specimens for enteric pathogens.

Early, aggressive nutrition is an important contributing factor of long-term neurodevelopmental outcomes. To ensure optimal growth in premature infants, adequate protein intake and optimal protein/energy ratio should be emphasized rather than the overall energy intake. Minimal enteral nutrition should be initiated as soon as possible in the first days of life, and feeding advancement should be individualized according to the clinical course of the infant. During hospitalization, enteral nutrition with preterm formula and fortified human milk represent the best feeding practices for facilitating growth. After discharge, the enteral nutrition strategy should be individualized according to the infant's weight at discharge. Infants with suboptimal weight for their postconceptional age at discharge should receive supplementation with human milk fortifiers or nutrient-enriched feeding, and the enteral nutrition strategy should be reviewed and modified continuously to achieve the target growth parameters.

Nutritional recovery was studied during continuous enteral nutrition in 29 patients who had developed malnutrition after gastric surgery. Patients were divided into three groups according to the type of surgery involved: total gastrectomy (n = 10), partial gastrectomy (n = 12), or cephalic pancreaticoduodenectomy (n = 7). The evolution of anthropometric and biological nutritional parameters in each group was compared with that observed in a control group of 10 nonoperated anorectic patients. Significant gains in body weight, arm muscle circumference, triceps skinfold, serum transferrin and global nutritional status were observed after 3 to 4 weeks of enteral nutrition in each group, while serum albumin, serum cholesterol, hemoglobin, and total lymphocyte count did not change significantly. No significant difference was observed between the groups. However, weight gain tended to be slower in patients with cephalic pancreaticoduodenectomy. This study confirms that enteral nutrition is an effective method of nutritional repletion after gastrectomy. Enteral nutrition can be used in undernourished gastrectomized patients when dietary measures alone have proven inadequate.

At present, there is limited evidence for the role of enteral nutrition as a primary therapy in cancer patients. Cachexia commonly occurs in patients with advanced cancer. A consensus view from a large number of studies suggests that cachexia cannot be fully reversed by vigorous enteral nutritional support. A review is included of the available data on the effects of enteral nutritional support on the common indices of nutritional state and on the final outcome of patients receiving enteral nutrition in conjunction with radiotherapy or chemotherapy, or both. The 'nutritional' effects are probably limited because the duration of the nutritional support in most studies consists of a few weeks while malnutrition in the cancer patients often occurs over many months.

Enteric viral infections in domestic animals cause significant economic losses. The recent emergence of virulent enteric coronaviruses [porcine epidemic diarrhea virus (PEDV)] in North America and Asia, for which no vaccines are available, remains a challenge for the global swine industry. Vaccination strategies against rotavirus and coronavirus (transmissible gastroenteritis virus) infections are reviewed. These vaccination principles are applicable against emerging enteric infections such as PEDV. Maternal vaccines to induce lactogenic immunity, and their transmission to suckling neonates via colostrum and milk, are critical for early passive protection. Subsequently, in weaned animals, oral vaccines incorporating novel mucosal adjuvants (e.g., vitamin A, probiotics) may provide active protection when maternal immunity wanes. Understanding intestinal and systemic immune responses to experimental rotavirus and transmissible gastroenteritis virus vaccines and infection in pigs provides a basis and model for the development of safe and effective vaccines for young animals and children against established and emerging enteric infections.

There are an increasing number of outbreaks of human pathogens related to fresh produce. Thus, the growth of human pathogens on plants should be explored. Human pathogens can survive under the harsh environments in plants, and can adhere and actively invade plants. Plant-associated microbiota or insects contribute to the survival and transmission of enteric pathogens in plants. Human enteric pathogens also trigger plant innate immunity, but some pathogens–such as Salmonella–can overcome this defense mechanism. PMID:25288993

This report describes psychological assessments of the first time ritual use of ayahuasca in the religious groups União do Vegetal and Santo Daime. Nineteen subjects who tried the beverage in Santo Daime rituals and nine subjects who tried it in União do Vegetal rituals were evaluated one to four days before their first ayahuasca experience in life and one to two weeks after this experience. Semistructured interviews and a structured psychiatric scale were used in the first evaluation to elicit set variables concerning attitudes towards the ayahuasca experience and to elicit mental health status. Mental health status was reassessed in the second evaluation, which also included a semistructured interview concerning the phenomenology of altered states of consciousness (ASCs). Predominantly positive expectancies concerning the ayahuasca experience were the most prominent findings concerning set variables. Visual phenomena, numinousness, peacefulness, insights and a distressing reaction were the most salient ASC experiences. A significant reduction of the intensity of minor psychiatric symptoms occurred in the Santo Daime group after the hallucinogen experience. Subjects in both groups reported behavioral changes towards assertiveness, serenity and vivacity/joy. The set and setting hypothesis, suggestibility processes, as well as the supposed unique effects of ayahuasca are used in discussing these findings.

Home visiting is an effective preventive intervention that can improve parenting outcomes for at-risk, new mothers, thereby optimizing subsequent child development. A history of maltreatment in childhood is common in mothers participating in home visiting, yet the extent to which such a history is related to parenting outcomes during home visiting is unknown. The current study evaluated whether mothers with a history of maltreatment in childhood respond less favorably to home visiting by examining the direct and indirect pathways to subsequent parenting stress, a key parenting outcome affecting child development. First-time mothers (N = 220; age range = 16-42) participating in one of two home visiting programs, Healthy Families America or Nurse Family Partnership, were evaluated at enrollment and again at 9-and 18-month post-enrollment assessments. Researchers administered measures of maternal history of maltreatment in childhood, depressive symptoms, social support, and parenting stress. Maternal history of maltreatment in childhood predicted worsening parenting stress at the 18-month assessment. Mediation modeling identified two indirect pathways, one involving social support at enrollment and one involving persistent depressive symptoms during home visiting, that explained the relation between a history of maltreatment in childhood and parenting stress at the 18-month assessment. Ways to improve the preventive effects of home visiting for mothers with a history of maltreatment in childhood through the identification of relevant intervention targets and their ideal time of administration are discussed.

This paper seeks to contribute to an understanding of the changing nature of support and information-seeking practices for women in the transition to first-time motherhood. In the context of increasing digitalisation, the significance of new virtual spaces for parenting is discussed. The paper demonstrates how women seek out alternative forms of expertise (specifically, non-medical expertise) and social support. The author argues for the importance of 'intimate mothering publics' through which women gather experiential information and practical support. These publics can act as a space for women to 'test' or legitimise their new identity as a mother. Intimate mothering publics are particularly useful for thinking about the meaning-making practices and learning experiences that occur during intimate online and face-to-face interactions. A variety of types of online support may be used during pregnancy. Surreptitious support in particular involves users invisibly receiving advice, information and reassurance that might otherwise be lacking. Access to intimate mothering publics is motivated by a number of factors, including feelings of community or acceptance, the desire to be a good mother or parent, emotional support and the need for practical and experiential advice.

Although suicide is a leading cause of death among new mothers during the postpartum period, there has been limited research on self-harm in the postpartum period and associated risk factors. One potential risk factor for suicidality (completed suicides, suicide attempts, and suicide ideation including thoughts of self harm) during the postpartum period is postpartum depression (PPD). In this study of women who gave birth for the first time between 1 January 2007 and 31 December 2011, 5,267 (9.9% of all who delivered) active component service women and 10,301 (8.2%) dependent spouses received incident PPD diagnoses during the one year postpartum period; 213 (0.4%) service women and 221 (0.2%) dependent spouses were diagnosed with incident suicidality. After adjusting for the effects of other covariates, service women with PPD had 42.2 times the odds to be diagnosed with suicidality in the postpartum period compared to service women without PPD; dependent spouses with PPD had 14.5 times the odds compared to those without PPD. The findings of this report suggest that a history of mental disorders was common among service women and dependent spouses with PPD in the postpartum period, and, in turn, PPD was a strong predictor for suicidality in the postpartum period. These results emphasize the importance of PPD screening during the postpartum period. They also suggest that additional focused screening for suicidal behavior among those already diagnosed with PPD may be warranted.

Youth who hold negative attitudes toward the justice system are more likely to engage in crime. It is particularly important to study attitudes early in someone's criminal career when they may still be open to change. To date, however, there has been no empirical test assessing whether the relation between attitudes and behavior changes after a first arrest. Using a sample of 1,216 first-time, male, juvenile offenders from the Crossroads Study, the present study explored: (a) racial/ethnic differences in the longitudinal patterns of youths' attitudes; and (b) reciprocal associations between youths' attitudes and both their offending behavior and rearrests in the 2.5 years after their first arrest. The results indicated that White youths' attitudes remained largely stable, Black youths' attitudes became more negative, and Latino youths' attitudes became more negative but only among Latino youth who reoffended. Although the results indicated that youths' attitudes were related to both offending and rearrest, the bidirectional relation between attitudes and offending weakened across time. After 2.5 years after their first arrest, attitudes no longer predicted offending or rearrests. These novel findings suggest that a youth's first contact is likely the most impactful. When it comes to young offenders' interactions with the justice system, first impressions matter. (PsycINFO Database Record
Enteral tube feeding is the delivery of nutritionally complete feed via a tube into the gut. It is used for patients who are unable to meet their nutritional needs orally. Enteral feeding can be given through a variety of different tubes that access the gastrointestinal tract either via the stomach or the small bowel. The contamination of enteral feed can often be overlooked as a source of bacterial infection. Enteral feeds can become contaminated in a variety of different ways. Most often infections result in extended lengths of stay in hospital and patients also need additional therapies and treatments in order to resolve these infections. Healthcare-associated infections not only affect the patients who acquire them but also have an impact on the staff involved in their care. Each acute trust will have its own local policies and guidelines regarding enteral feeding and infection control and prevention. These local documents will be based on national initiatives and guidelines. It is important for nurses to refer to their local policies and guidelines before they start a patient on enteral feeding to ensure that they are doing so in the safest manner possible. Nurses' practice is key to preventing bacterial contamination in such patients.

The purpose of this study was to investigate the frequency of enteral feeding intolerance in critically ill septic burn patients, the effect of enteral feeding intolerance on the efficacy of feeding, the correlation between the infection marker (procalcitonin [PCT]) and the nutrition status marker (prealbumin) and the impact of feeding intolerance on the outcome of septic burn patients. From January 2009 to December 2012 the data of all burn patients with the diagnosis of sepsis who were placed on enteral nutrition were analyzed. Septic patients were divided into two groups: group A, septic patients who developed feeding intolerance; group B, septic patients who did not develop feeding intolerance. Demographic and clinical characteristics of patients were analyzed and compared. The diagnosis of sepsis was applied to 29% of all patients. Of these patients 35% developed intolerance to enteral feeding throughout the septic period. A statistically significant increase in mean PCT level and a decrease in prealbumin level was observed during the sepsis period. Group A patients had statistically significant lower mean caloric intake, higher PCT:prealbumin ratio, higher pneumonia incidence, higher Sequential Organ Failure Assessment Maximum Score, a longer duration of mechanical ventilation, and a higher mortality rate in comparison with the septic patients without gastric feeding intolerance. The authors concluded that a high percentage of septic burn patients developed enteral feeding intolerance. Enteral feeding intolerance seems to have a negative impact on the patients' nutritional status, morbidity, and mortality.
