Familial environment in high- and middle-low-income municipalities: a survey in Italy to understand the distribution of potentially obesogenic factors.

OBJECTIVES: To explore the familial and social environment in high- and middle-low-income municipalities in Italy to evaluate the distribution of potentially obesogenic factors. A hybrid methodological approach was chosen. A survey of 1215 Italian children was performed to collect information regarding child, family and peer characteristics; additionally, income data were derived from national estimates based on zip codes. STUDY DESIGN: A cross-sectional study conducted via computer-assisted telephone interviews (CATI). METHODS: A CATI facility was used to interview 1215 Italian children aged 6-10 years. Information regarding family composition; body mass index (BMI) of the child, father and mother; mother's perception of the child's weight; levels of physical activity of the child, father and mother; time spent watching television or playing video games; use of social networks; leisure-time habits; and dietary habits of peers was collected. Income per year per person was obtained from the Italian National Institute of Statistics estimates. Municipalities were divided into two groups: one representing the highest ranking income from the total Italian income distribution, and one representing middle-low incomes. Differences between middle-low-income and high-income groups for child and parent BMIs, social networks, and dietary and leisure-time habits were compared using Wilcoxon and McNemar tests, as appropriate. Multivariate analysis was conducted using logistic regression. RESULTS: In total, 604 high-income children and 611 middle-low-income children were identified. A significant difference in father's BMI was found between middle-low- and high-income groups: 10.5% of fathers in middle-low-income municipalities were obese, compared with 3.8% in high-income areas (P < 0.001). On the contrary, this analysis found no association between income group and the mother's BMI. In this sample, middle-low-income children participated in less physical activity than high-income children (22.7% vs 34.8% participated in sporting activities for more than 3 h per week, P < 0.001), and spent more time in sedentary activities, such as watching television. However, middle-low-income children were not isolated and were surrounded by a wider social network than high-income children (80.4% vs 69% had more than three friends, P < 0.001). CONCLUSIONS: Significant differences were found in the distribution of obesogenic behaviours between middle-low- and high-income municipalities, suggesting that social factors as well as the physical environment should be considered in the development of health policies and interventions to reduce childhood obesity.

Risk posed to children by stationery items in the upper airways.

AIM: The aim of the present study is to characterize the risk of complications and prolonged hospitalization due to stationery items according to age and gender of patients, FB characteristics and foreign body (FB) location, circumstances of the accident, as emerging from the ESFBI study. METHODS: A retrospective study in major hospitals of 19 European countries was realized on children aged 0-14 having inhaled/aspired or ingested a stationery item. In the years 2000-2003 a total of 2094 FB injuries occurred in children aged 0-14 years. The characteristics of the child, the FB consistency and the occurrence of complications were analyzed. RESULTS: Among FB injuries, 62 (3%) were due to a stationery item: 32 were due to objects insertion in the ears while 30 occurred in the upper and lower respiratory tract. Objects most frequently involved are parts of pens in children younger than 3 years and eraser in older. 39% of children needed hospitalization. The most documented complication was inflammation of external ear. Almost 24% of injuries happened under adults' supervision. CONCLUSION: Injuries are events that in many cases can be prevented with appropriate strategies. Passive environmental strategies, including product modification by manufacturers, are the most effective. Our study testifies that stationary is involved in a non negligible percentage of FB injuries. This results confirm the fact that when passive preventive strategies are not practical, active strategies that promote behaviour change are necessary and information about this issue should be included in all visits to family pediatricians.

Comparison of randomized and non-randomized controlled trials evidence regarding the effectiveness of workplace exercise on musculoskeletal pain control.

Evidence synthesized based on randomized controlled trials (RCT) results are recognized as the pinnacle of research excellence; however, the conduction of RCT in workplace environment is not always possible. This study comparatively reviewed evidence from RCT and non-RCT studies in which participants performed workplace exercise for musculoskeletal pain control. Up to February 2011, PubMed, MEDLINE, Embase, Cochrane, PEDro and Web of Science databases were searched. All trials that evaluated workplace exercise interventions for controlling musculoskeletal pain were included. The PEDro scale was used to rate the studies' quality, PRISMA and Cochrane recommendations were applied, and association between frequencies of effect size categories (small, moderate, large) from various outcomes by study type was tested (2x3 contingency table). The search yielded 10239 references in English, from which 21 RCT and 12 non-RCT were selected. Both groups of studies presented methodological flaws including descriptions of randomization, blinding of examiners and absence of intention-to-treat analysis for the RCT, and further absence of controls and blind assessor for the non-RCTs. RCTs had significantly more moderate and large effect size reported in their results compared to non-RCTs (p=0.04). Considering the difficulties in randomizing participants in occupational settings, all studies would benefit from better describing pertinent methodological information.

[Effects of residents' care needs classification (and misclassification) in nursing homes: the example of SOSIA classification]. / Effetti della classificazione (e mis-classificazione) del case- mix nella rappresentazione dei bisogni degli ospiti delle Re- sidenze Socio-Assistenziali per Anziani non Autosufficienti (RSA): l'esempio della Scheda di OSservazione Intermedia dell'Assistenza (SOSIA).

Since 2003, the Lombardy region has introduced a case-mix reimbursement system for nursing homes based on the SOSIA form which classifies residents into eight classes of frailty. In the present study the agreement between SOSIA classification and other well documented instruments, including Barthel Index, Mini Mental State Examination and Clinical Dementia Rating Scale is evaluated in 100 nursing home residents. Only 50% of residents with severe dementia have been recognized as seriously impaired when assessed with SOSIA form; since misclassification errors underestimate residents' care needs, they determine an insufficient reimbursement limiting nursing home possibility to offer care appropriate for the case-mix.

A systems biology approach: new insights into fetal growth restriction using Bayesian Networks.

IL-6, IGF-II and IGFBP-2 concentrations in placental lysates were previously shown to be associated with foetal growth. This study aimed to apply a Bayesian Network (BN) model in order to investigate complex dependencies among biochemical and clinical factors and fetal growth outcome. Twenty-one Intra-Uterine Growth Restricted (IUGR) and 25 Appropriate for Gestational Age (AGA) pregnancies were followed throughout pregnancy. Information was collected on maternal and gestational age, neonatal gender, previous gynaecological history. Total protein content, IGF-II, IGFBP-1, IGFBP-2, IL-6, and TNF-alpha concentrations in placental lysates were measured, and IGF-I, IGF-II, IGFBP-1, IGFBP-2 and IL-6 relative gene expression in placenta assessed. A BN and a hybrid forecasting system were implemented: BN revealed a key role of maternal age and TNF-alpha on IUGR and confirmed a close relationship among IGF-II, IL-6 and foetal growth. A relationship between duration of gestation, appropriateness for gestational age, and placental IL-6 concentration was also confirmed. Compared with other techniques, BN showed a better accuracy. Findings confirmed a major role of maternal age in addition to IGF-II, IL-6 and TNF-alpha in IUGR. A direct role of IGFBP-2 was not shown. BN confirmed to be useful in understanding the system's biology and graphically representing variable relationships and hierarchy, particularly where, as in IUGR, many interactions among predictors exist.

Nutritional profiles in a public health perspective: a critical review.

Nutritional profiling is defined as 'the science of categorizing foods according to their nutritional composition' and it is useful for food labelling and regulation of health claims. The evidence for the link between nutrients and health outcomes was reviewed. A reduced salt intake reduces blood pressure, but only a few randomized controlled trials have verified the effect of salt on overall and cardiovascular mortality. Evidence linking a reduced fat intake with cardiovascular mortality and obesity is generally non-significant. Studies that have examined the relationship between obesity and diet have produced contrasting results. A simulation exercise that demonstrated that the impact of a reduced salt and fat intake on overall mortality would be negligible in the European population was carried out. Consideration of the literature and the results of this simulation exercise suggest that the introduction of nutritional profiles in Europe would be expected to have a very limited impact on health outcomes.

Foreign bodies causing asphyxiation in children: the experience of the Buenos Aires paediatric ORL clinic.

Inhalation or aspiration of a foreign body (FB) occurs relatively frequently in young children. The size, shape, type and site of arrest of the FB lead to variability in the clinical picture. The present study included data from 65 cases of FB inhalation presenting over 1 year at the Children's Hospital Gutierrez, Buenos Aires, Argentina, compared with information from four well-known published case series chosen as representative of other cultural and geographical backgrounds: the USA, Europe, North Africa (Egypt) and Asia (India). The mean age of children studied was 4.03 years. Injuries happened mainly at home (53 cases [81.54%]) and under adult supervision (59 cases [90.77%]). The most frequently inhaled FB was nuts, however, in contrast to previous reports, the majority of incidents involved inhalation of an inorganic, rather than an organic (food) FB. Complications included pneumonia (three cases), atelectasis (two cases) and pneumonitis (one case). No deaths were recorded. These data suggest that children play with objects inappropriate for their age, such as pins and nails, that adults may not be aware of the choking risks, and that more effort is required in educating caregivers about these risks.

Hospitalization rate as a proxy for the quality of life evaluation: the case of dilated cardiomiopathy.

RATIONALE, AIMS AND OBJECTIVES: Some objective indicators like symptoms, toxicity, performance status, rate of hospitalization or re-employment have been already employed in scientific literature as proxies of Quality of Life assessment, and, in spite of the intrinsic limitations of such a measurement, they represent a valuable source of information in all the situations where a formal assessment is impossible, due to budget, time or human resources constrains. We concentrate here on some models for the analysis of frequency of hospitalization data and we discuss an application to the Hearth Muscle Disease Study Group data. METHODS: A sample of 235 patients with dilated cardiomyopathy (DCM) prospectively treated at the Department of Cardiology (Trieste, Italy) have been observed during a period of 18 years, from 1978 to 1992 and data regarding hospitalization history were collected. The hospitalization process depends on the time since the last event, and usually is a function of a set of explanatory variables, such as the current state of the patient, treatments he has been receiving and the severity of disease. We propose here a semi-Markov representation of the hospitalization process, and we analyze data regarding DCM, implementing Exponential, Weibull, and Cox models; in Cox models we take care also of the stratification according to the duration or to the levels of the state factor. RESULTS: The probability of experiencing a second hospitalization within one year after the first one is estimated about 0.50, and within two years about 0.30. After this point the probability remains constant at a 0.10 level. The same pattern is observed for the second hospitalization, while things are getting worse after the third hospitalization, when the probability of not having a subsequent hospitalization is about 0.10 within one year. Betablockers have a strong influence in enlarging the time interval spent between an hospitalization and the other. CONCLUSIONS: The hospitalization process can be viewed only as a rough approximation of the good standing of the patient. However, for diseases like DCM can be reasonable, because of the relatively fast increment in the worsening conditions of the patients and the consequently high chances of observing new hospitalizations up to the absorbing state (the death). Moreover a very detailed modeling of the process leads to extract as much information as possible from the data.
