Italian Euromelanoma Day Screening Campaign (2005-2007) and the planning of melanoma screening strategies.
2011
Although no study has definitively shown that unfocused screening of skin cancer is effective, many campaigns have been organized with the aim of increasing awareness on melanoma risk factors. The objective of this study was to analyse the results of the Skin Cancer Screening Day in Italy during the period 2005-2007, to determine the priorities for melanoma control plans in a Mediterranean country. A total of 5002 patients were screened by dermatologists in 31 cities. Individuals who considered themselves to have many naevi and those with a family history of melanoma showed a higher number of common and atypical naevi. Ten melanomas, 20 basal cell carcinomas and two squamous cell carcinomas…
Introduction to chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS).
2007
Prostatitis is the most frequently diagnosed illness in men under 50, accounting for about 8% of all consultations with urologists. Estimates based on published studies suggest that the incidence of prostatitis in the population is somewhere between 4% and 11%. In 1995 the National Institutes of Health (NIH) classified prostatitis into 4 main categories: 1) acute bacterial; 2) chronic bacterial; 3) pelvic pain syndrome; 4) asymptomatic inflammatory. The aetiological agent most often involved is bacterial, particularly the category of Gram (-) bacteria, followed by Gram (+), chlamydiae and mycoplasms; however many cases of prostatitis are caused by bacteria which are difficult to isolate or …
Correlation of Crystallin Expression and RGC Susceptibility in Experimental Glaucoma Rats of Different Ages.
2018
Glaucoma is one of the leading causes of blindness worldwide with age being an important risk factor. However, the pathogenesis remains poorly understood. Aim of this study was to focus on age-dependent molecular changes in an experimental animal model of glaucoma.Intraocular pressure was elevated in Sprague-Dawley rats aged 3, 14, and 47 weeks for a period of 7 weeks by episcleral vein cauterization. Ganglion cell loss was monitored by an immunohistochemical staining of the Brain-specific homeobox/POU (Pit-1, Oct-2, Unc-86) domain protein 3A positive cells in retinal flat-mounts and spectral-domain optical coherence tomography measuring the retinal nerve fiber layer thickness. Molecular pr…
Whole exome sequencing and system biology analysis support the "two-hit" mechanism in the onset of Ameloblastoma
2021
Background Ameloblastoma is the most frequent odontogenic tumor. Various evidence has highlighted the role of somatic mutations, including recurrent mutation BRAF V600E, in the tumorigenesis of Ameloblastoma, but the intact genetic pathology remains unknown. Material and Methods We sequenced the whole exome of both tumor tissue and healthy bone tissue from four mandibular ameloblastoma patients. The identified somatic mutations were integrated into Weighted Gene Co-expression Network Analysis on publicly available expression data of odontoblast, ameloblast, and Ameloblastoma. Results We identified a total of 70 rare and severe somatic mutations. We found BRAF V600E on all four patients, sup…
Lifestyle, psychological, socioeconomic and environmental factors and their impact on hypertension during the coronavirus disease 2019 pandemic.
2020
SUMMARY: The coronavirus disease 2019 (COVID-19) pandemic considerably affects health, wellbeing, social, economic and other aspects of daily life. The impact of COVID-19 on blood pressure (BP) control and hypertension remains insufficiently explored. We therefore provide a comprehensive review of the potential changes in lifestyle factors and behaviours as well as environmental changes likely to influence BP control and cardiovascular risk during the pandemic. This includes the impact on physical activity, dietary patterns, alcohol consumption and the resulting consequences, for example increases in body weight. Other risk factors for increases in BP and cardiovascular risk such as smoking…
Anemia prevalence in women of reproductive age in low- and middle-income countries between 2000 and 2018
2021
Anemia is a globally widespread condition in women and is associated with reduced economic productivity and increased mortality worldwide. Here we map annual 2000–2018 geospatial estimates of anemia prevalence in women of reproductive age (15–49 years) across 82 low- and middle-income countries (LMICs), stratify anemia by severity and aggregate results to policy-relevant administrative and national levels. Additionally, we provide subnational disparity analyses to provide a comprehensive overview of anemia prevalence inequalities within these countries and predict progress toward the World Health Organization’s Global Nutrition Target (WHO GNT) to reduce anemia by half by 2030. Our results …
The influence of risk factors on the onset and outcome of psychosis: What we learned from the GAP study
2020
The GAP multidisciplinary study carried out in South London, recruited 410 first episode of psychosis patients and 370 controls; the aim was to elucidate the multiple genetic and environmental factors influencing the onset and outcome of psychosis. The study demonstrated the risk increasing effect of adversity in childhood (especially parental loss, abuse, and bullying) on onset of psychosis especially positive symptoms. Adverse life events more proximal to onset, being from an ethnic minority, and cannabis use also played important roles; indeed, one quarter of new cases of psychosis could be attributed to use of high potency cannabis. The “jumping to conclusions” bias appeared to mediate …
Airway hyperresponsiveness in the elderly: prevalence and clinical implications.
2005
Airway hyperresponsiveness is associated with an increased risk of developing respiratory symptoms. The assessment of airway hyperresponsiveness can provide valuable information regarding the natural course of respiratory diseases. However, little information is available for populations of more advanced age, and data are conflicting. It was assessed whether age influences the occurrence of airway hyperresponsiveness by reviewing those studies that specifically addressed this issue, and attempting to identify the factors responsible for discrepancies between studies. Eighteen studies, published between 1983 and 2002, are included in this review. Overall, the results of the analysis are in f…
Elevation of total serum immunoglobulin E is associated with asthma in nonallergic individuals.
2000
Elevated serum immunoglobulin (Ig)E is the hallmark of atopy, and contributes to asthma and bronchial hyperresponsiveness in atopic individuals. In contrast, the significance of IgE in nonallergic subjects is less clear. The aim of the present study is to clarify a potential association of IgE and asthma in absence of clinical allergy. To this purpose 1,219 consecutive patients of a pulmonary practice were evaluated. Nonallergic patients were defined by negative skin prick test, history of atopy and specific IgE, 509 subjects (42%) were nonallergic. Among these, 80 patients (16%) had elevated total IgE levels (150 U x mL(-1)). Prevalence and severity of asthma in nonallergic subjects with I…
Associations of diet and lifestyle factors with common volatile organic compounds in exhaled breath of average-risk individuals.
2018
Background Detection of diseases via exhaled breath remains an attractive idea despite persisting gaps in understanding the origin of volatile organic compounds (VOCs) and their relationship with the disease of interest. Data on factors potentially influencing the results of breath analysis remain rather sparse and often controversial. In this study, we aimed to investigate the associations of common VOCs in exhaled breath of average-risk individuals with socio-demographic and lifestyle factors, medical conditions as well as diet. Methods Alveolar breath samples of 1447 men and women were collected in the morning after fasting and were analyzed using gas-chromatography linked with mass-spec…
