Derivation of occupational exposure limits: Differences in methods and protection levels

Frameworks for deriving occupational exposure limits (OELs) and OEL-analogue values (such as derived-no-effect levels [DNELs]) in various regulatory areas in the EU and at national level in Germany were analysed. Reasons for differences between frameworks and possible means of improving transparency and harmonisation were identified. Differences between assessment factors used for deriving exposure limits proved to be one important reason for diverging numerical values. Distributions for exposure time, interspecies and intraspecies extrapolation were combined by probabilistic methods and compared with default values of assessment factors used in the various OEL frameworks in order to investigate protection levels. In a subchronic inhalation study showing local effects in the respiratory tract, the probability that assessment factors were sufficiently high to protect 99% and 95% of the target population (workers) from adverse effects varied considerably from 9% to 71% and 17% to 87%, respectively, between the frameworks. All steps of the derivation process, including the uncertainty associated with the point of departure (POD), were further analysed with two examples of full probabilistic assessments. It is proposed that benchmark modelling should be the method of choice for deriving PODs and that all OEL frameworks should provide detailed guidance documents and clearly define their protection goals by stating the proportion of the exposed population the OEL aims to cover and the probability with which they intend to provide protection from adverse effects. Harmonisation can be achieved by agreeing on the way to perform the methodological steps for deriving OELs and on common protection goals.     

Calendario de vacunaciones de la Asociación Española de Pediatría: recomendaciones 2021

The CAV-AEP annually publishes the immunisation schedule considered optimal for all children and adolescent resident in Spain, taking into account the available evidence.The 2 + 1 schedule is recommended (2, 4, and 11 months) with hexavalent vaccines (DTPa-VPI-Hib-HB) and with 13-valent pneumococcal conjugate.A 6-year booster is recommended, preferably with DTPa (if available), with a dose of polio for those who received 2 + 1 schemes, as well as vaccination with Tdpa in adolescents and in each pregnancy, preferably between 27 and 32 weeks.Rotavirus vaccine should be systematic for all infants.Meningococcal B vaccine, with a 2 + 1 schedule, should be included in routine calendar.In addition to the inclusion of the conjugated tetravalent meningococcal vaccine (MenACWY) at 12 years of age with catch up to 18 years, inclusive, the CAV recommends this vaccine to be also included at 12 months of age, replacing MenC. Likewise, it is recommended in those over 6 weeks of age with risk factors or who travel to countries with a high incidence of these serogroups.Two-dose schedules for triple viral (12 months and 3-4 years) and varicella (15 months and 3-4 years) will be used. The second dose could be applied as a tetraviral vaccine.Universal systematic vaccination against HPV is recommended, regardless of gender, preferably at 12 years, and greater effort should be made to improve coverage. The 9 genotype extends coverage for both genders.     

Organization of the 43rd European Congress of Cytology in the SARS–CoV-2 pandemic period: A report

The 43rd European Congress of Cytology in Wrocław, Poland, was held as a hybrid meeting in the Fall of 2021. After nearly 2 years without in-person cytology conferences, the 43rd Congress represents 1 of the first major international scientific meetings to occur during the severe acute respiratory syndrome-coronavirus 2 pandemic. Since March 2020, the pandemic situation substantially modified the organization of scientific meetings because of both domestic and international travel restrictions, new health standards, and concern among participants, resulting in new alternative forms of virtual conferencing.

Mortalidad por complicaciones médicas y quirúrgicas,impacto de la crisis y gasto sanitario en España, 2002-2013

ObjectiveTo describe the evolution of mortality risks for complications due to medical care or surgery between the periods prior to (2002-2007) and after (2008-2013) the beginning of the economic crisis for Spain and by autonomous region, and to analyse the relationship between the changes in the risks of death and the socioeconomic impact of the crisis and the variation in health spending.MethodEcological study based on age-standardized mortality rates, synthetic index of vulnerability as a socioeconomic indicator and variation in health expenditure as an indicator of health expenditure. The relative risk of death between periods was estimated with Poisson regression models.ResultsThe number of deaths increased for Spain in the period studied. Although the relationship between the increase in public investment in health and the decrease in mortality due to this cause has not been clearly demonstrated, it was possible to determine that the autonomous regions with the lowest increase in health expenditure had rates higher than the rest throughout the period, and that the most vulnerable to the crisis and with the lowest increase in spending presented the greatest increase in the risk of death between the periods.ConclusionsGiven the increase in these deaths, due to avoidable failures of the system, it is necessary to continue investigating this cause of mortality.     

Real world outcomes with Bortezomib Thalidomide dexamethasone and Cyclophosphamide Bortezomib dexamethasone induction treatment for transplant eligible multiple myeloma patients in a Latin American country. A Retrospective Cohort Study from Grupo Argentino de Mieloma Múltiple

Data about treatment outcomes and toxicity in Latin America are scarce. There are differences with central countries based on access to healthcare system and socioeconomic status. Argentinean Society of Hematology recommends bortezomib-based triplets for induction treatment of transplant eligible newly diagnosed multiple myeloma patients. Most common options are CyBorD (cyclophosphamide, bortezomib and dexamethasone) and VTD (bortezomib, thalidomide and dexamethasone). Main goal of our retrospective, multicentric study was to compare very good partial response rate (VGPR) or better after induction treatment in a real-world setting in Argentina. Secondary objectives included comparison of complete response (CR) post-induction and after bone marrow transplantation, grade 3-4 adverse events (AEs), progression-free survival (PFS) and overall survival (OS). Three hundred twenty-two patients were included (median age at diagnosis: 57 years; 52% male; 28% had ISS3; 14% with high-risk cytogenetics; median follow up: 34 months). CyBorD was indicated in 74% and 26% received VTD. In VTD arm, 72.62% of patients achieved at least VGPR vs 53.36% receiving CyBorD (odds ratio, OR: 1.96 [95% confidence interval, CI: 1.08-3.57; P = .026] after adjusting by age, ISS [International Staging System], lactate dehydrogenase levels (LDH) and cytogenetic risk. Difference in VGPR was 19.26% (95% CI: 15-24). CR rate were 35.92% (VTD) vs 22.55% (CyBorD) (adjusted OR: 2.13 [95% CI: 1.12-4.05]). Difference in CR was 13.37% (95% CI: 9.6-17.53). Adverse events (AEs) were more common with VTD (69.05% vs 55.46% for CyBorD; P = .030), especially grade 3-4 neuropathy (P = .005) and thrombosis (P = .001). Thromboprophylaxis was inadequate in 20.24% of patients. Hematological AEs were more common with CyBorD, especially thrombocytopenia (P = .017). PFS and OS at 24 months were not different between treatments. In this real-world setting, VTD was associated with better CR and VGPR than CyBorD. Nevertheless, CyBorD continues to be the preferred induction regimen in Argentina, based on safety profile. Frontline autologous stem cell transplantation improves quality of responses, especially in countries with limited access to new drugs.
