Hide Abstract
In many centers, Stage I-II melanoma patients are considered "cured" after 10 years of disease-free survival and follow-up visits are interrupted. However, melanoma may relapse also later. We retrospectively analyzed a cohort of 1,372 Stage I-II melanoma patients who were disease-free 10 years after diagnosis. The aim of this study was to characterize patients who experienced a late recurrence and to compare them to those who remained disease-free to identify possible predictive factors. Multivariate Cox proportional-hazards regression analyses were carried out to evaluate the influence of different factors on the risk of recurrence. Seventy-seven patients out of 1,372 (5.6%) relapsed, 52 in regional sites and 25 in distant ones. The majority of patients (31 out of 52) experienced late recurrence in regional lymph nodes. Brain and lung were the most common site of single distant recurrence (24% each). Patients with multiple distant metastases showed a brain and lung involvement in, respectively, 40 and 48% of cases. A Cox proportional-hazards regression model analysis showed the independent role of age under 40 years, Breslow thickness >2 mm, and Clark Level IV/V in increasing the risk of Late Recurrence. These patients should be followed-up for longer than 10 years. The pattern of recurrence suggests that melanoma cells can be dormant preferentially in lymph nodes, brain and lung. A particular attention should be reserved to these anatomic sites during the follow-up after 10 years of disease-free.

[SENTIERI KIDS: monitoring children's health in Italian polluted sites].
Epidemiol Prev
PUBLISHED: 07-03-2014
Show Abstract
Hide Abstract
Protecting children's health from the effects of environmental contamination is a public health priority. In recent years, particular care has been devoted in Italy to the study of the relationship between environmental pollutants and health during infancy. The SENTIERI Project has called attention to increases in infant mortality in National Priority Contaminated Sites (NPCSs). SENTIERI KIDS provides a blueprint for the establishment of a task force charged with establishing multi and inter-disciplinary cooperation between central and regional institutions on the subject of children's health in contaminated sites. SENTIERI KIDS introduces a multiple outcome analytical model based on updated health outcomes (mortality, cancer incidence, hospital discharges) in order to establish a permanent observation system to monitor the state of health of infants residing in contaminated areas. This will pave the way for more in-depth epidemiological enquiries on an individual basis, and support the establishment and continued monitoring of primary prevention projects. Particular attention is devoted to issues of information and communication.

The MOBI-Kids Study Protocol: Challenges in Assessing Childhood and Adolescent Exposure to Electromagnetic Fields from Wireless Telecommunication Technologies and Possible Association with Brain Tumor Risk.
Front Public Health
PUBLISHED: 01-01-2014
Show Abstract
Hide Abstract
The rapid increase in mobile phone use in young people has generated concern about possible health effects of exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF). MOBI-Kids, a multinational case-control study, investigates the potential effects of childhood and adolescent exposure to EMF from mobile communications technologies on brain tumor risk in 14 countries. The study, which aims to include approximately 1,000 brain tumor cases aged 10-24?years and two individually matched controls for each case, follows a common protocol and builds upon the methodological experience of the INTERPHONE study. The design and conduct of a study on EMF exposure and brain tumor risk in young people in a large number of countries is complex and poses methodological challenges. This manuscript discusses the design of MOBI-Kids and describes the challenges and approaches chosen to address them, including: (1) the choice of controls operated for suspected appendicitis, to reduce potential selection bias related to low response rates among population controls; (2) investigating a young study population spanning a relatively wide age range; (3) conducting a large, multinational epidemiological study, while adhering to increasingly stricter ethics requirements; (4) investigating a rare and potentially fatal disease; and (5) assessing exposure to EMF from communication technologies. Our experience in thus far developing and implementing the study protocol indicates that MOBI-Kids is feasible and will generate results that will contribute to the understanding of potential brain tumor risks associated with use of mobile phones and other wireless communications technologies among young people.

More than 20 years of registration of type 1 diabetes in Sardinian children: temporal variations of incidence with age, period of diagnosis, and year of birth.

Hide Abstract
We analyzed Sardinian registry data to assess time trends in incidence rates (IRs) of type 1 diabetes during the period 1989-2009 (2,371 case subjects 0-14 years of age). Poisson regression models were used to estimate the effects of sex, age, period of diagnosis, and birth cohorts. IR was 44.8 cases/100,000 person-years (95% CI 43.1-46.7). The annual increase was 2.12% (1.45-2.80; test for linear trend, P < 0.001). For boys, the increasing trend was evident up to 5 years of age and for girls up to 8 years of age. Compared with the 1989-1994 birth cohort, the relative risk increased from 0.78 (0.61-1.10) in 1974-1979 to 1.62 (1.18-2.23) in 2004-2009. The increase over period was less striking, with a tendency to regress in more recent years. The best-fitting model for boys included age and a linear time trend, and for girls age and nonlinear effects of calendar period and birth cohort. In conclusion, incidence increased over time, and the increase tended to level off in more recent years by calendar period but not by birth cohort, with some evidence of a stronger increase among girls than boys. Should the increase be attributable to the effects of some perinatal environmental factor, this would mean that such a factor has started affecting females before males.

Second malignancies after childhood noncentral nervous system solid cancer: Results from 13 cancer registries.
Int. J. Cancer
PUBLISHED: 03-28-2011
Show Abstract
Hide Abstract
Children diagnosed with noncentral nervous system solid cancers (NCNSSC) experience several adverse late effects, including second malignant neoplasm. The aim of our study was to assess the risk of specific second malignancies after a childhood NCNSSC. Diagnosis and follow-up data on 10,988 cases of NCNSSC in children (0-14 years) were obtained from 13 registries. Standardized incidence ratios (SIRs) with 95% confidence intervals (CI) and cumulative incidence of second malignancies were computed. We observed 175 second malignant neoplasms, yielding a SIR of 4.6, 95% CI: 3.9-5.3. When considering second cancers with at least 10 occurrences, highest relative risks were found for second malignant bone tumors (SIR = 26.4, 16.6-40.0), soft tissue sarcomas (SIR = 14.1, 6.7-25.8) and myeloid leukemia (SIR = 12.7, 6.3-22.8). Significant increased risks for all malignancies combined were observed after sympathetic nervous system tumors (SIR = 11.4, 5.2-21.6), retinoblastomas (SIR = 7.3, 5.4-9.8), renal tumors (SIR = 5.7, 3.8-8.0), malignant bone tumors (SIR = 5.6, 3.7-8.2), soft tissue sarcomas (SIR = 4.7, 3.2-6.8), germ-cell, trophoblastic and other gonadal neoplasms (SIR = 2.5, 1.1-4.9), carcinomas and other malignant epithelial neoplasms (SIR = 2.2, 1.4-3.3). The highest risk of a second malignancy of any type occurred 5 to 9 years after NCNSSC (SIR = 9.9, 6.8-13.9). The cumulative incidence of second malignancies 10 years after the first neoplasm was eight times higher among NCNSSC survivors than in the general population, with the absolute difference between observed and expected cumulative incidence still increasing after 50 years of follow-up. Children who survived a NCNSSC experience a large increased risk of developing a new malignancy, even many years after their initial diagnosis.

Sepsis is a common and severe complication in premature neonates, particularly those with very low birth weight (VLBW) (<1500 g). Whether lactoferrin, a mammalian milk glycoprotein involved in innate immune host defenses, can reduce the incidence of sepsis is unknown. In animal models, the probiotic Lactobacillus rhamnosus GG (LGG) enhances the activity of lactoferrin but has not been studied in human infants.

Life after childhood cancer: marriage and offspring in adult long-term survivors--a population-based study in the Piedmont region, Italy.
Eur. J. Cancer Prev.
PUBLISHED: 09-08-2009
Show Abstract
Hide Abstract
The majority of childhood cancer cases survive to adulthood. We describe the experience of marriage and reproduction as indicators of quality of life, in a population-based cohort of adult long-term survivors after early cancer reported to the Childhood Cancer Registry of Piedmont. The study included 1237 survivors with a malignant neoplasm diagnosed during 1967-2000 when aged 0-14 years, who attained age 18 years. Vital and marital status and number of offspring were assessed through the Vital Statistics Offices. Marriage and fertility deficits were estimated by comparison with the Piedmont population. Among the individuals included in this study, 919 (74.3%) never married and never lived as married. The marriage deficit was 32% [observed/expected 0.68; 95% confidence interval (CI): 0.55-0.83] in men and 18% (observed/expected 0.82; 95% CI: 0.68-0.98) in women. A total of 179 children were born to 120 women, with a fertility deficit of 41% (observed/expected 0.59; 95% CI: 0.51-0.69). In conclusion, the observed decrements in marriage in men and women and fertility in women suggest that efforts should be made to improve the recovery from physical and psychological traumas related to diagnosis and treatment of cancer.

Mortality and prognosis in patients with neurogenic orthostatic hypotension.
Funct. Neurol.
Show Abstract
Hide Abstract
The prognosis of neurogenic orthostatic hypotension (NOH) has been poorly studied. The aim of this study was to evaluate retrospectively comorbidities and causes of death in patients with NOH. Clinical information and causes of death were obtained for 104 patients (45 with multiple system atrophy, 9 with pure autonomic failure, 43 with Parkinsons disease, and 7 with other types of autonomic neuropathy) referred to the Autonomic Unit from 1996 to 2009. Cardiovascular diseases (hypertension, cardiac comorbidities, atrial fibrillation and heart failure) were present in 53 (51%) NOH patients. At the end of follow-up, 44 patients were deceased. Type of NOH was the main factor associated with mortality. The main causes of death were infectious/respiratory (54%) and cardiac (16%). In NOH patients, cardiovascular diseases are frequent, although mortality is mainly due to infectious and respiratory causes. Detection of cardiovascular diseases may be useful in the choice of anti-hypotensive treatments.

Hierarchical regression for multiple comparisons in a case-control study of occupational risks for lung cancer.
PLoS ONE
Show Abstract
Hide Abstract
Occupational studies often involve multiple comparisons and therefore suffer from false positive findings. Semi-Bayes adjustment methods have sometimes been used to address this issue. Hierarchical regression is a more general approach, including Semi-Bayes adjustment as a special case, that aims at improving the validity of standard maximum-likelihood estimates in the presence of multiple comparisons by incorporating similarities between the exposures of interest in a second-stage model.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
