    Obesity: epidemics or crisis worldwide?

    No full text
    The rapid increase in the level of obesity and overweight worldwide is recognized as a major health problem: obesity poses a major risk for serious dietrelated diseases, including diabetes mellitus, cardiovascular disease, hypertension, stroke and cancer; therefore, it increases the risk of premature death.[1] In particular, abdominal obesity - an increased amount of intra-abdominal fat - has been associated with a number of cardiovascular disease (CVD) risk factors, CVD and all-cause mortality [2]. Recent research demonstrated that high BMI values are associated with increased sympathetic activity, which results in decreased Heart Rate Variability (HRV). [3] Obesity can also be related to psychiatric disorders. [4,5] Some research suggests that depression and anxiety might lead to obesity through the adoption of an inactive lifestyle; however, the opposite direction is also possible. [6] The rising epidemic reflects the profound changes in society and in behavioural patterns of communities over recent decades. While genes are important in determining a person's susceptibility to weight gain, energy balance is determined by calorie intake and physical activity [7]. Economic growth, modernization, urbanization and globalization of food markets are just some of the forces thought to underlie the obesity trend. Based on the existing prevalence, trend data and the epidemiological evidence linking obesity with health conditions, it is reasonable to describe obesity as a public health crisis that severely impairs the quality of life, adds to national health care budgets.

    Background Cervical cancer is third in incidence and fourth in mortality among cancers of women worldwide. Screening-test, such as conventional cytology, are used to identify pre-cancers, to prevent the occurrence of invasive cancers or to diagnose an early stage of disease, permitting a well-timed treatment. This systematic review and meta-analysis investigates the effective- ness of pap test in the prevention of cervical cancer. Methods A systematic review and meta-analysis were performed. The literature review, from 1979 to 2013, was based on Pubmed, Scopus, Google Scholar and ISI engines using the keywords ‘‘pap test AND study design (RCT, cohort, case-control, cross sectional) AND cervical cancer’’. The selection of articles was carried out independently by four authors. Predefined study quality indicators were applied for evaluation of articles: Jadad scale was used for randomized clinical trials (RCTs) and New Castle-Ottawa Scale for other studies. Four different meta- analyses were carried out, one for each study design, using the RevMan software version 5 for Windows. Results From the 3372 screened citations, 360 met our inclusion criteria (86 cohort, 119 RCT, 62 cross-sectional and 93 case- control). All papers were selected for title, abstract and study design pertinence. Up to 81 doublets, 871 cohort, 526 RCT, 1046 cross sectional and 669 case-control studies were excluded. Meta-analysis shows that Pap test reduces mortality from and incidence of advanced cervical cancer compared to no screening [mortality risk ratio (RR) 0.65, 95% CI 0.47-0.90; incidence RR 0.56, 95% CI 0.42-0.7]. In a cohort study pap test reduced the risk of invasive cervical cancer diagnosis compared to no screening (RR 0.38, 95% CI = 0.23-0.63. Furthermore, a history of two negative Pap test rather than one is associated with a decreased risk of developing cancer of the cervix (OR 1.33, 95% CI 0.93-1.90 vs OR 1.55, 95% CI 1.15-2.10). Conclusions Pap test is an effective screening tool, it is protective and associated with a reduced risk of incidence of and mortality for advanced cervical cancer. Risk-relative should be stratified for women’s age, ethnic group, number of previous pap smears, and time of follow-up. Key messages - Cytological screening programs play a major role in reducing both incidence and mortality of invasive cervical cancers. - The importance of Pap-test in early diagnosis of cervical can- cer remains unaltered despite the availability of new screen- ing methods, different HPV-DNA tests and HPV vaccines

    How to report a review? [Come si scrive una review?]

    No full text
    In this contribution we would like to underline another issue: how to report a review? The need of specific reporting guidelines for medical journals is beyond dispute. With that regard a number of statements were developed by groups of experts to facilitate reporting of research studies. Most medical journals, including British Medical Journal (BMJ), the Journal of the American Medical Association (JAMA), The Lancet, and New England Journal of Medicine, often require compliance to all or some of the following guidelines: CONSORT Statement (reporting of randomized controlled trials), STARD (reporting of diagnostic accuracy studies), STROBE (reporting of observational studies in epidemiology), PRISMA (reporting of systematic reviews and meta-analyses) and MOOSE (reporting of meta-analyses of observational studies). The present letter concerns the standards of reporting in research, publication in medical journals and wishes to give an emphasis to the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) statement. There is no doubt that, according to the PRISMA statement [2], the number of authors for a systematic review needs to be at least 2 (“Eligibility assessment to be performed independently in an unblended standardized manner by 2 reviewers”)

    Background Research on the integration of genomic knowledge into clinical practice and public health is in an early phase, and many concerns remain. The aim of this study is to identify, classify, and evaluate delivery models for the provision of predictive genetic testing in Europe vs. extra-European (Anglophone) countries. Methods A systematic review of the literature was conducted to identify existing genetic delivery models. Inclusion criteria were that articles be: published 2000-2015; in English or Italian; and from European or non-European countries (Canada, USA, Australia or New Zealand). Additional policy documents were retrieved from represented countries’ government-affiliated websites (non-systematic search). Results A total of 117 records were included, reporting on 148 genetic programmes. The programmes integrated into healthcare systems were 99 (64.9%), 49 (33.1%) were pilot programmes and 4 (2.7%) were direct-to-consumer genetic services. Most programmes were delivered in the United Kingdom (58, 39.2%), USA (35, 23.6%) or Australia (16, 10.8%). Tests for hereditary breast and ovarian cancer and Lynch syndrome were most commonly offered (39.9% and 12.8% of programmes, respectively). Many of the genetic tests offered have insufficient clinical validity or utility. The identified genetic programmes can be classified into five basic genetic service models based on which type of healthcare professional has the most prominent role in test referral: I) the geneticists model; II) the primary care model; III) the medical specialists model; IV) the population screening programmes model; V) and the direct-to-consumer model. Rudimentary evaluation of the identified programmes will be made based on outcomes and process measures of the models. Conclusions This review, as part of an European multicenter study, will facilitate the identification of appropriate models, outcome and process measures for the provision of predictive genetic testing in Europe

    Identification of delivery models for the provision of genetic testing, policies governing the use of genomic applications and evaluation of genetic services: a multicentre study

    The provision of genetic services, along with research in the fields of genomics and genetics, has evolved in recent years to meet the increasing demand of consumers interested in prediction of genomic diseases and various inherited traits (e.g. ability in sports, nutrigenomics, ancestry, etc.). Consumer demand and commercial interests have paved the way for the premature introduction, in the public and private healthcare sectors, of genetic tests with insufficient data on analytical and clinical validity, as well as clinical utility. There is also lack or insufficient evidence of cost-effectiveness of several genetic applications already introduced in clinical and public health practice. These concerns contribute to the lack of evidence on what constitutes an optimal genetic service delivery model, defined as the broad context within the Public Health Genomics framework in which genetic services are offered to individuals and families with or at risk of genetic disorders. The aim of this dissertation is to identify existing genetic service delivery models, policies governing the use of genomic applications, and measures to evaluate genetic testing and related services in Europe and extra-European (Anglophone) countries (Canada, USA, Australia, or New Zealand). Two methodological approaches have been employed, a systematic review of the literature and a cross-sectional study addressing healthcare professionals with good knowledge and/or experience on the provision of BRCA1/2, Lynch syndrome, familial hypercholesterolemia, and inherited thrombophilia genetic testing, policies on genetic applications and evaluation of genetic services. The identification and evaluation of existing genetic service delivery models are important steps towards the enhancement and standardization of genetic service provision. Current models of genetic services require the integration of genetics in all medical specialties, collaboration among different healthcare professionals, and redistribution of professional roles. Prior to implementation in clinical and public health practice, genetic tests should be evaluated based on available efficacy and cost-effectiveness data and offered to the citizens as right to benefit from innovative healthcare. The proper implementation of genomics application in mainstream medicine can be achieved through professional education, training, adequate funding, public policies, and public awareness of the field of genomic medicine

    The aim of the current study is to review current regulations relatively to medical requirements necessary to achieve suitability to fly of the cabin crew. There are three classes of flight crew medical standards and licensing. A first class medical certificate is required for all pilots who perform professional flights or skydiving instructors. A second class medical certificate is required only for persons who do not perform professional flights, skydiving activities or any other professional activity related to aircraft piloting (cabin crew, holders of Light Aircraft Pilot’s Licence - LAPL, remote pilot operators). Finally, a third class medical certificate is required for workers engaged in air traffic control
