Frequency of metabolic syndrome in women treated at the Menopause Clinic of the “Dr. José Eleuterio González” University Hospital of the UANL in Northeastern Mexico

Objectives: To determine the frequency of metabolic syndrome (MS) in patients with menopause, and to compare the incidence of MS between surgical and natural menopause. Methods: This was an observational, longitudinal, descriptive, retrospective, unblinded study of cases seen at the Menopause Clinic of the University Hospital “Dr. José eleuterio González” of the Universidad Autónoma de Nuevo León from March 2009 to December 2011. The frequency of MS was determined based on Adult Treatment Panel III (ATPIII) classiication. Results: at the end of the study, 391 patients were evaluated. The mean age was 50.1 years. We found a frequency of MS of 38.1%, the risk factor most often found was low HDL-cholesterol (62.5%), followed by obesity (46.5%), hypercholesterolemia (42.3%), hyperglycemia (11.5%), and hypertension (7.7%). The incidence of natural and surgical menopause was 37.6% vs. 39.2% respectively; however, the result was not statistically signiicant (p = 0.093). Conclusions: Patients with menopause are at increased risk of developing MS. it is important to detect MS early in this of patients, when they have one risk factor to avoid complications which may trigger the syndrome. We recommend screening for MS during perimenopause, in order to detect and try to delay it in a timely manner and recommend primary prevention (diet and exercise), or secondary prevention in cases with one or more risk factors.

Sensitization to indoor aeroallergens in children who attended the Allergy Service of the “Dr. José Eleuterio González” University Hospital of Monterrey, Mexico

Background: Indoor aeroallergens are the main cause of sensitization in children and represent a risk factor for the development of allergic diseases. Objective: Identify the major indoor aeroallergens most often sensitized to pediatric patients treated at the Allergy Service at the “Dr. José Eleuterio González” University Hospital of Monterrey Methods: We performed an observational and descriptive study where we reviewed reports of positive skin tests to the following common indoor aeroallergens: Dermatophagoides farinae (D. farinae), Dermatophagoides pteronyssinus (D. pteronyssinus), Canis familiaris (C. familiaris), Felis domesticus (F. domesticus), Blattella germanica (B. germanica) and Periplaneta americana (P. americana), found in patients under 16 years with symptoms of allergy, during the period of 2011-2012. Results: We performed 439 skin tests to aeroallergens in pediatric patients. Of these, 57.6% were male and 42.4% were female. Mean age was 6.3 years. The age groups were under 3 years: 17.8%, 3-5 years: 35%, 6-12 years: 36%, and 13-16 years: 11.2%. The main diagnoses were: allergic rhinitis (71.8%), asthma (16.6%), and atopic dermatitis (4.3%). In 57.9% of the cases, they had at least one positive skin test to any aeroallergen. The rate of sensitization to speciic aeroallergens was: D. Pteronyssinus 49.0%, D. farinae 44.6%, B. germanica 13.9%, P. Americana 10.9%, F. domesticus 10.7%, and C. familiaris 5.9%. Conclusion: Indoor aeroallergen sensitization can occur early in life, although it was more frequent in the preschooler and elementary school group. Dust house mites were the most commom cause of allergic sensitization.

Nutritional screening and prevalence of hospital malnutrition risk. University Hospital of the UANL, Monterrey

Introduction: Hospital malnutrition risk has prevalence values of 20%-50%, and it is a major health problem in the health institutions worldwide. Objective: To assess the accomplishment of nutritional screening and the prevalence of hospital malnutrition risk in a University Hospital. Materials and methods: A retrospective analysis was carried out with nutritional screening, using primary data from six clinical areas obtained in the period between July 2012 and December 2013. According to previous results in Mexican health institutions and considering a mean malnutrition risk prevalence of 50%, it was calculated that a sample size of 3200 subjects was required for the assessment of valid risk values. Patients with values ≥3 on the Nutritional Risk Screening (NRS, 2002) were classiied as carriers of nutritional risk. Results: A total of 5611 patients (38% of all patients admitted) were studied. The rate of screening declined from 55% in 2012 to 31% in 2013. During the whole period, 3034 patients were classiied with risk of malnutrition (54% prevalence). Conclusions: The prevalence of hospital malnutrition risk was high. The accomplishment of the nutritional screening was deicient, and declined between 2012 and 2013. The lack of nutritional screening does not meet the vital care requirements of hospitalized patients and prevents the timely treatment of those at malnutrition risk.

Person-centred information to parents in paediatric oncology (the PIFBO study) : A study protocol of an ongoing RCT

Background: Parents of children with cancer experience a demanding situation and often suffer from psychological problems such as stress. Trying to coping with the complex body of information about their child's disease is one factor that contributes to this stress. The aim of this study is to evaluate an intervention for person-centred information to parents of children with cancer that consists of four sessions with children's nurses trained in the intervention method. Methods/Design: This is a multi-centre RCT with two parallel arms and a 1:1 allocation ratio. The primary outcome is illness-related parental stress. Secondary outcomes are post-traumatic stress symptoms, anxiety, depression, satisfaction with information, expected and received knowledge, and experiences with health care providers. A process evaluation is performed to describe experiences and contextual factors. Data are collected using web questionnaires or paper forms according to the parents' preference, audio recording of the intervention sessions, and qualitative interviews with parents and the intervention nurses. Discussion: Few studies have evaluated information interventions for parents of children with cancer using large multi-centre RCTs. This intervention is designed to be performed by regular staff children's nurses, which will facilitate implementation if the intervention proves to be effective. Trial registration: Clinical trials NCT02332226 (December 11, 2014).

Detectability of migrating raptors and its effect on bias and precision of trend estimates

Annual counts of migrating raptors at fixed observation points are a widespread practice, and changes in numbers counted over time, adjusted for survey effort, are commonly used as indices of trends in population size. Unmodeled year-to-year variation in detectability may introduce bias, reduce precision of trend estimates, and reduce power to detect trends. We conducted dependent double-observer surveys at the annual fall raptor migration count at Lucky Peak, Idaho, in 2009 and 2010 and applied Huggins closed-capture removal models and information-theoretic model selection to determine the relative importance of factors affecting detectability. The most parsimonious model included effects of observer team identity, distance, species, and day of the season. We then simulated 30 years of counts with heterogeneous individual detectability, a population decline (λ = 0.964), and unexplained random variation in the number of available birds. Imperfect detectability did not bias trend estimation, and increased the time required to achieve 80% power by less than 11%. Results suggested that availability is a greater source of variance in annual counts than detectability; thus, efforts to account for availability would improve the monitoring value of migration counts. According to our models, long-term trends in observer efficiency or migratory flight distance may introduce substantial bias to trend estimates. Estimating detectability with a novel count protocol like our double-observer method is just one potential means of controlling such effects. The traditional approach of modeling the effects of covariates and adjusting the index may also be effective if ancillary data is collected consistently.

Learning experience and identity development as a research assistant /

What research learning experiences do current students have as research assistants (RAs) in the Faculty of Education at Brock University? How do the experiences of research assistants contribute to the formation of a researcher identity and influence future research plans? Despite the importance of these questions, there seems to be very little research conducted or written about the experiences of research assistants as they engage in the research process. There are few resources to which research assistants or their advisors can refer regarding graduate student research learning experiences. The purpose of this study was to understand the kinds of learning experiences that 4 RAs (who are enrolled in the Faculty of Education at Brock University, St. Catharines, Ontario) have and how those experiences contribute to their identities as researchers. Through interviews with participants, observations of participants, and textual documents produced by participants, I have (a) discovered what 4 RAs have learned while engaged in one or more research assistantships and (b) explored how these 4 RAs' experiences have shaped their identities as new researchers. My research design provided a separate case study for each participant RA, including myself as a research participant. Then as a collective, I studied all 4 cases as a case study in itself in the form of a cross-analysis to identify similarities and differences between cases. Using a variety of writing forms and visual narratives, I analyzed and interpreted the experiences of my participants utilizing arts-based literature to inform my analysis and thesis format. The final presentation includes electronic diagrams, models, poetry, a newsletter, a website presentation, and other representational arts-based forms.This thesis is a resource for current and future research assistants who can learn from the research assistant experiences presented in the research. Faculty members who hire research assistants to assist them with their research will also benefit from reading about RAs' learning experiences from the RAs' perspective. The information provided in this thesis document is a resource to inform future policies and research training initiatives in faculty departments and offices at universities. Consequently, this thesis also informs researchers (experienced and inexperienced) about how to conduct research in ways that benefit all parties and provide insight into potential ways to improve research assistantship practices.

Stolen past: Shattered futures, aboriginal justice in Canada

It is acknowledged that Canada's criminal justice system has some major flaws, particularly with respect to its application to various ethnic subgroups. Aboriginal Canadians are one subgroup particularly sensitive to the problems in the system as is reflected by their disproportionately high rates of criminality and incarceration. Over the past 50 years many programs have been developed and recommendations have been made to alleviate the tensions Aboriginals find within the system. However, the situation today is essentially the same. Aboriginals are still overrepresented within the system and solutions that have been brought forward have had little success in stemming their flow into the system. Blame for Aboriginal mistreatment in the system has been placed at all levels from line police officers to high-level officials and politicians and attempts to resolve problems continue as an on going process. However, many of the recommendations and reforms have revolved around culture conflict. Although this thesis recognizes the importance of culture conflict in the overrepresentation of Aboriginals within the Canadian criminal justice system, it has also recognized that culture conflict alone is not responsible for all the flaws within the system as it pertains to Aboriginals. This thesis is of the opinion that in order for reforms to the criminal justice system to be successful, the context in which the system is operating must also be considered. Variables such as geographic isolation, economic disparity and social/political stability are viewed as operating in conjunction with culture, ultimately influencing Aboriginal treatment within the system. The conclusions drawn from this study confirm that when these factors operate together, the overrepresentation of Aboriginals within the Canadian criminal justice system is inevitable. Thus all three variables, culture conflict (social/political stability being part), geographic isolation and economic disparity must be address within the system if any significant changes in the crime rates or incarceration rates of Aboriginals is to be expected. In addition, primary research indicated the influence of cooperation as a factor in moderating the effects of criminality; not just cooperation among Aboriginals and non-Aboriginals, but also cooperation among differing Aboriginal communities. It was argued that when all these issues are addressed, Aboriginal peoples in Canada will have the strength to repair their shattered futures.

Profitable opportunities around macroeconomic announcements in the U.S. Treasury market

This thesis studies the impact of macroeconomic announcements on the U.S. Treasury market and investigates profitable opportunities around macroeconomic announcements using data from the eSpeed electronic trading platform. We investigate how macroeconomic announcements affect the return predictability of trade imbalance for the 2-year, 5-year, IO-year U.S. Treasury notes and 30-year U.S. Treasury bonds. The goal of this thesis is to develop a methodology to identify informed trades and estimate the trade imbalance based on informed trades. We use the daily order book slope as a proxy for dispersion of beliefs among investors. Regression results in this thesis indicate that, on announcement days with a high dispersion of beliefs, daily trade imbalance estimated by informed trades significantly predicts returns on the following day. In addition, we develop a trade-imbalance based trading strategy conditional on dispersion of beliefs, informed trades, and announcement days. The trading strategy yields significantly positive net returns for the 2-year T-notes.
