Hematological malignancies in the island of Sardinia, 1974-1993: age and sex distributions and temporal changes in incidence

We have collected, by an active retrospective survey, all the cases of hematologic malignancies (HM) newly diagnosed during the time period 1974–1993 in the resident population of Sardinia. Diagnosis was deemed valid, after consultation of clinical records, in more than 90% of the 7264 collected cases. The number of newly diagnosed cases by year more than doubled during the 20-year period investigated. This striking increase can be only partially accounted for by ageing of population. Indeed, age-specific and age-adjusted rates of most of HM increased during this period, although Hodgkin Disease (HD), Chronic Myeloid Leukemia (CML) and Acute Lymphoblastic Leukemia (ALL) were notable exceptions. The observed increase in rates is likely, in a large part, to be fictitious, due to easier access to a health care system, which in the meantime, improved its diagnostic efficiency. This was particularly evident for Chronic Lymphocytic Leukemia (CLL), Multiple Myeloma (MM) and some others myelo- and lympho-proliferative disorders, but its relevance declined after 1984–1989. A likely true increase in occurrence was evidenced for Non-Hodgkin Lymphomas (NHL) and similarly, although to a lesser extent and more doubtful, for Myelodysplasias (MDS) and Acute Myeloid Leukemia (AML). At the end of the studied period each type of HM presented age and sex distributions and ageadjusted rates that show only minor differences from those reported for other western countries. No argument emerged to suggest that any genetic peculiarities of the Sardinian population might have affected the occurrence of HM. The confounding effects of improved diagnostic efficiency have prevented a reliable assessment of influence on incidences of environmental and socio-economic changes that, in relatively recent times, have occurred in Sardinia

Suspected adverse reactions to medications and food supplements containing Serenoa repens: A worldwide analysis of pharmacovigilance and phytovigilance spontaneous reports

: The safety of Serenoa repens (SR)-containing products was evaluated conducting a retrospective worldwide analysis of pharmaco- and phytovigilance report forms of suspected adverse reactions (SARs) collected up to 31 January 2022. Multivariate logistic regression was performed to estimate the odds ratios (ORs) of serious SAR. A total of 1810 report forms were analysed; 92% of subjects were males, with a median age of 69 years; 44% of cases were defined as serious. Subjects exposed to dietary supplements had a higher risk of developing serious SARs (OR: 1.60 [95% CI: 1.20-2.15]), as subjects exposed to 2-5 (OR: 1. 83 [95% CI: 1.30-2.58]) or more than 5 (OR: 3.45 [95% CI: 2.36-5.06]) suspect/interacting products. The probability of experiencing serious SAR was higher for subjects exposed to concomitant products (OR: 1.55 [95% CI: 1.15-2.08]), to more than four active compounds (OR: 4.38 [95% CI: 3.21-5.99]) and to SR for more than 14 days (OR: 1.89 [95% CI: 1.10-3, 22]), and lower for subjects exposed to higher doses of SR (OR: of 0.34 [95% CI: 0.20-0.58]). This evidence improves awareness on safety of SR containing products, suggesting the need of a further update of periodic reviews by national and international regulatory agencies
