No full textIMPACT OF VARICELLA VACCINATION IN CHILDREN UNDER 1 YEAR OF AGE IN ITALY (2006-2011)
Full text linkINTRODUCTION
Varicella represents the most widespread vaccine
preventable childhood infectious disease in Italy.
In children under 1 year of age, it tends to be
more severe with a higher rate of complications
like pneumonia, hepatitis and encephalitis, and is
associated with higher mortality. In Italy, between
2003 and 2010, 8/21 Regions have progressively
introduced Universal Varicella Vaccination (UVV)
in their immunization programs, with different
schedules in children aged 13-15 months and
5-6 years. Objective of this study was to analyze
hospitalization rates (HR) in children under 1 year
of age, by the different vaccination policies in Italy
in 2006-2011.
PATIENTS AND METHODS
We performed a retrospective review of
hospitalization data from Italian hospital discharge
forms, provided by the Ministry of Health. We
considered the codes 052.0-052.9 by ICD9-
CM system (primary or secondary diagnosis).
HR of varicella in children under 1 year of age
were calculated by different vaccination policies
(referring to the year 2008) in 3 different areas:
area 1, with a UVV policy (Veneto, Sicilia, Puglia,
Toscana), area 2, with policy of vaccinating
susceptible adolescents and at-risk population
(Piedmont, Friuli Venetia Giulia, Liguria, Lazio,
Campania, Basilicata, Calabria, Sardinia) and area
3 with vaccination of only at-risk population (the
remaining regions). The denominator for HR was
calculated using resident population aged less than
1 year numbers according to ISTAT.
RESULTS
10,483 hospitalizations for varicella were
identified in patients of any age. The peak in
varicella hospitalizations was observed in the
first year of life. In this age group varicella was
responsible of 13.7% of hospitalizations. 71.5%
of cases in primary diagnosis (PD) were varicella
without mention of complications, followed by the
varicella with other specified complication (9.6%).
32 diagnosis reported post-varicella encephalitis
and 15 hemorrhagic pneumonia. When varicella
diagnosis was reported as secondary (SD), the
most frequent PD were pneumonia or respiratory
failure (25.7%). Annual HR globally declined in
this age group from 56.4 to 34.2/100,000 children.
The greatest HR were in area 3 and they declined
from 63.9 to 44/100,000. In area 2 HR declined
from 55.6 to 43.1/100,000, and in area 1 HR
significantly decreased from 49.3 to 11.5/100,000
(test for trend, p < 0.001) (Fig. 1).
CONCLUSIONS
This study demonstrated that varicella continues
to represent a relevant health problem in Italy,
especially in the pediatric age. Data obtained by
the Italian Regions that first introduced universal
vaccination demonstrated that it allows to reduce
the incidence of varicella and hospitalization rates
Prevalence and correlates for self-reported sleep problems among nursing students
No full text"Introdution. University students report significantly worse sleep. quality than the general population. Sleep problems are related to. increased health concerns, irritability, depression, fatigue, attention. and concentration difficulties, along with poor academic performance.. The aim of this paper is to conduct a survey based on. a questionnaire that would characterize night time and daytime. habits in nursing students to estimate the prevalence of chronic. insomnia, sleep disturbance and their correlates.. Methods. We conducted a cross-sectional survey among 364. nursing students of the University of L’Aquila, in Italy. Self-reported. sleep data were derived from Sleep and Daytime Habits. Questionnaire” (S&DHQ) that covered sleep and daytime habits. and academic progress. Anxiety and depression symptoms were. assessed by the Mental Health Invenctory-5 (MHI-5) questionnaire.. A supplement includes information about lifestyle, health. status and physical activity.. Results. The overall prevalence of insomnia was 26,7%. It. increased significantly from 10,3% for students aged 40 years. The prevalence of sleep problems. were 9,4% for disorders of initiating sleep, 8,3% for disrupted. sleep, 7,7% for early morning awakening and subjectively. poor quality of sleep 22,3%. Multiple logistic regression analysis. showed that greater age was significantly associated with an. increased risk of insomnia. Other risk predictors of insomnia were. headache, severe depression and self perception of poor quality. of life. Daytime sleepiness and morning tiredness were significantly. associated with current smoking habit and painful physical. condition. The risk of unsatisfactory academic progress increased. significantly in students reported poor sleep quality.. Discussion. Our study demonstrates that sleep problems are very. common among students, and supports the need to assess sleep problems. and identify students at risk regarding school achievement.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Temporal trends in rate of hospitalization for rotavirus gastroenteritis in the pediatric population in Italy: cross sectional study utilizing national Hospital Discharge Database
No full textStudy design. This was a retrospective observational study, conducted using hospitalization data from national Hospital Discharge Database (HDD) available on the website of the Italian Ministry of Health. Objective The primary objectives were to estimate the frequency of hospitalization for Rotavirus gastroenteritis (RVGE) for the period 2002-2005 in children aged 0-14 years in the different regions of Italy, and to analyze temporal trends of hospitalization rates (HR) for geographical location. Methods. In Italy there are no specific surveillance systems for RV disease in place, so HDD are one mean by which diseases trends among hospitalizations may be observed. Cases of RVGE were identified using ICD9-CM code 00861. Three aged groups are studied: 0-1, 1-4 , and 5-14 years. In order to estimate HR, we used population for each study year published by the National Institute of Statistic website. Data analysis was performed using STATA 12. The nptrend command was used to examine for significant trends in temporal HR (p0.05). Conclusions. The highest HR observed in the Northern compared to the rest of Italy could reflect actual geographic variability in incidence of rotavirus infection or disease, or could be due to differences in the sensitivity of the hospital discharge databases for detecting RVGE
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
