Abstract
Azacitidine/venetoclax is an active regimen in patients with newly diagnosed AML. However, primary or secondary resistance to azacitidine/venetoclax is an area of unmet need and overexpression of MCL-1 is suggested to be a potential resistance mechanism. Pevonedistat inhibits MCL-1 through activation of NOXA, and pevonedistat/azacitidine has previously shown activity in AML. To assess the tolerability and efficacy of adding pevonedistat to azacitidine/venetoclax in relapsed/refractory AML, we conducted a phase I multicenter openlabel study in 16 adults with relapsed/refractory AML. Patients were treated with azacitidine, venetoclax along with pevonedistat intravenously on days 1, 3 and 5 of each 28-day cycle at 10, 15 or 20 mg/m2 in successive cohorts in the dose escalation phase. The impact of treatment on protein neddylation as well as expression of pro-apoptotic BCL2 family members was assessed. The recommended phase II dose of pevonedistat was 20 mg/m2. Grade 3 or higher adverse events included neutropenia (31%), thrombocytopenia (13%), febrile neutropenia (19%), anemia (19%), hypertension (19%) and sepsis (19%). The overall response rate was 46.7% for the whole cohort including complete remission (CR) in 5 of 7 (71.4%) patients who were naïve to the hypomethylating agent/venetoclax. No measurable residual disease (MRD) was detected in 80.0% of the patients who achieved CR. The median time to best response was 50 (range: 23 - 77) days. Four patients were bridged to allogeneic stem cell transplantation. The combination of azacitidine, venetoclax and pevonedistat is safe and shows encouraging preliminary activity in patients with relapsed/refractory AML. (NCT04172844).

Abstract
KEY HIGHLIGHTS 1. Measles eradication is the ultimate goal but it is premature to set a date for its accomplishment. Existing regional elimination goals should be vigorously pursued to enable setting a global target by 2020. 2. The basic strategic approaches articulated in the Global Measles and Rubella Strategic Plan 2012-2020 are valid to achieve the goals but have not been fully implemented (or not appropriately adapted to local situations). 3. The report recommends a shift from primary reliance on supplementary immunization activities (SIAs) to assure two doses of measles-containing vaccine (MCV) are delivered to the target population to primary reliance on ongoing services to assure administration of two doses of MCV. Regular high quality SIAs will still be necessary while ongoing services are being strengthened. 4. The report recommends a shift from primary reliance on coverage to measure progress to incorporating disease incidence as a major indicator. 5. The report recommends that the measles/rubella vaccination program be considered an indicator for the quality of the overall immunization program and that measles/rubella incidence and measles and rubella vaccination coverage be considered as primary indicators of immunization program performance. 6. Polio transition presents both risks and opportunities: risks should be minimized and opportunities maximized. 7. A school entry immunization check could contribute significantly to strengthening overall immunization services with assurance that recommended doses of measles and rubella vaccines as well as other vaccines have been delivered and providing those vaccines at that time if the child is un- or under-vaccinated. 8. Program decisions should increasingly be based on good quality data and appropriate analysis. 9. The incorporation of rubella vaccination into the immunization program needs to be accelerated - it should be accorded equivalent emphasis as measles. 10. Outbreak investigation and response are critical but the most important thing is to prevent outbreaks.

Abstract
Eradication is the permanent reduction to zero of the worldwide incidence of infection caused by a specific agent as a result of deliberate efforts; intervention measures are no longer needed. To date, the only infectious disease that has been eradicated is smallpox. Poliomyelitis is targeted for eradication by the year 2000, and the eradication initiative is well under way, with the Western Hemisphere certified as being polio-free and more than one year having passed since polio cases occurred in the Western Pacific Region of the World Health Organization. A review of the technical feasibility of eradicating other diseases preventable by vaccines currently licensed for civilian use in the United States indicates that measles, hepatitis B, mumps, rubella, and possibly disease caused by Haemophilus influenzae type b are potential candidates. From a practical point of view, measles seems most likely to be the next target. Global capacity to undertake eradication is limited, and care must be taken to ensure that a potential measles eradication effort does not impede achievement of polio eradication. Even in the absence of eradication, major improvements in control are both feasible and necessary with existing vaccines. New and improved vaccines may give further possibilities of eradication in the future. Eradication represents the ultimate in sustainability and social justice.

Abstract
Measles incidence is at a nadir in many parts of the world due to vaccination efforts. Although the technical feasibility of eradication has been acknowledged, financial and political commitment need to be concomitantly identified on the national and global level. We demonstrate the potential value of measles eradication by identifying the potential cost-savings to one country resulting from measles eradication. For the US, measles eradication would save $45 million annually. If achieved by the year 2010, the US would save $500 million to $4.1 billion depending on the year of elimination, post-eradication schedule and discount rate. Intensification of measles control efforts in the US beyond current levels would have minimal marginal benefits on disease burden reduction. Allocation of resources to achieve global measles eradication is the next level of efficiency which would provide substantial savings. Countries may adapt this model to estimate their savings for consideration of the required political and financial contribution towards a global measles eradication program.

Abstract
The product of the p53 tumor suppressor gene has a well-documented activity as a transcriptional activator, and several studies indicate that this function is at least in part essential for the ability of p53 to suppress cellular proliferation. However, there is growing evidence that some activities of wild-type p53 may be independent of its trans-activation function; in fact, recent investigations have indicated that the transcriptional repression function of p53, rather than its trans-activation function, may be influential in p53-mediated apoptosis. The focus of this study has been on the identification of genes that exhibit decreased expression during p53-dependent apoptosis, and therefore represent potential p53-repressed genes influential in programmed cell death. This report identifies the gene encoding the microtubule-associated protein MAP4 as one whose mRNA and protein expression decrease in cells following induction of wild-type p53. Importantly, decreased MAP4 expression following p53 induction can be inhibited by molecules that prevent p53-mediated transcriptional repression and apoptosis, such as the adenovirus E1B-19K protein and the Wilms tumor gene product WT1. Additionally, overexpression of MAP4 in cells induced to undergo p53-dependent apoptosis significantly delays this process, indicating that the negative regulation of this gene by p53 may be influential in the rapid progression of apoptosis.

Abstract
Despite fears that child day care attendance enhances the transmission of infection among attending children, there are positive aspects of the day care experience that, from the standpoint of infectious diseases, directly and indirectly contribute to the child's well-being. Quality child day care first requires a preadmission physical examination and then requires that the child begin the series of prescribed immunizations, which might not have been received if care were provided at home by a care giver who was not knowledgeable of available mechanisms for the prevention of disease. Once enrolled, the child and parents can be exposed to health education, which benefits them in terms of overall good health for the entire family. The child day care environment, like every other place where children congregate, is subject to the transmission of infectious agents among child and staff. But the risk of infection can be minimized and the health benefits maximized, and child day care can make positive contributions toward the social and physical development of the child.
