Traditional metrics used to assess the outcomes and impact of biomedical research, such as publications, citations, and follow-up grant funding, do not measure the impact on changes in health practice (standard of care), policy, guidelines, or other societal outcomes and may not be meaningful to stakeholders, such as patients, donors, or the public. Susan G. Komen has developed a research product tracking system to monitor the progress of Komen-funded research products along the research pipeline and to measure the potential impact on patients more directly. In the Komen Product Tracking System, each funded grant is classified by product potential (e.g., treatment, biomarker, etc.) and by stage in the research pipeline (e.g., basic research, preclinical research, clinical trials, and regulatory approval/commercialization). Progress through the research pipeline is updated each year while the grant is active. The Komen Product Tracking System can be used to assess outcomes and the impact of Komen-funded research in several ways by viewing snapshots at a given time to understand what research products are in the pipeline at that time and what stages they are in, viewing new products added during a defined funding period and, most importantly, assessing how many products have progressed in the research pipeline and have contributed to, or have potential to contribute to, practice changes that result in direct impacts on patients. The tracking system enables us to communicate the impact of our research to our donors, patients, the public, and other stakeholders in a more meaningful way.The classical SEIR model, being an autonomous system of differential equations, has important limitations when representing a pandemic situation. Particularly, the geometric unimodal shape of the epidemic curve is not what is generally observed. This work introduces the βSEIR model, which adds to the classical SEIR model a differential law to model the variation in the transmission rate. It considers two opposite thrives generally found in a population first, reaction to disease presence that may be linked to mitigation strategies, which tends to decrease transmission, and second, the urge to return to normal conditions that pulls to restore the initial value of the transmission rate. Our results open a wide spectrum of dynamic variabilities in the curve of new infected, which are justified by reaction and restoration thrives that affect disease transmission over time. Some of these dynamics have been observed in the existing COVID-19 disease data. In particular and to further exemplify the potential of the model proposed in this article, we show its capability of capturing the evolution of the number of new confirmed cases of Chile and Italy for several months after epidemic onset, while incorporating a reaction to disease presence with decreasing adherence to mitigation strategies, as well as a seasonal effect on the restoration of the initial transmissibility conditions.In addition to laser photocoagulation, therapeutic interventions for diabetic retinopathy (DR) have heretofore consisted of anti-VEGF drugs, which, besides drawbacks inherent to the treatments themselves, are limited in scope and may not fully address the condition's complex pathophysiology. This is because DR is a multifactorial condition, meaning a gene therapy focused on a target with broader effects, such as the mechanistic target of rapamycin (mTOR), may prove to be the solution in overcoming these concerns. Having previously demonstrated the potential of a mTOR-inhibiting shRNA packaged in a recombinant adeno-associated virus to address a variety of angiogenic retinal diseases, here we explore the effects of rAAV2-shmTOR-SD in a streptozotocin-induced diabetic mouse model. Delivered via intravitreal injection, the therapeutic efficacy of the virus vector upon early DR processes was examined. rAAV2-shmTOR-SD effectively transduced mouse retinas and therein downregulated mTOR expression, which was elevated in sham-treated and control shRNA-injected (rAAV2-shCon-SD) control groups. mTOR inhibition additionally led to marked reductions in pericyte loss, acellular capillary formation, vascular permeability, and retinal cell layer thinning, processes that contribute to DR progression. Immunohistochemistry showed that rAAV2-shmTOR-SD decreased ganglion cell loss and pathogenic Müller cell activation and proliferation, while also having anti-apoptotic activity, with these effects suggesting the therapeutic virus vector may be neuroprotective. Taken together, these results build upon our previous work to demonstrate the broad ability of rAAV2-shmTOR-SD to address aspects of DR pathophysiology further evidencing its potential as a human gene therapeutic strategy for DR.We urgently need answers to basic epidemiological questions regarding SARS-CoV-2 infection in pregnant and postpartum women and its effect on their newborns. While many national registries, health facilities, and research groups are collecting relevant data, we need a collaborative and methodologically rigorous approach to better combine these data and address knowledge gaps, especially those related to rare outcomes. We propose that using a sequential, prospective meta-analysis (PMA) is the best approach to generate data for policy- and practice-oriented guidelines. As the pandemic evolves, additional studies identified retrospectively by the steering committee or through living systematic reviews will be invited to participate in this PMA. Investigators can contribute to the PMA by either submitting individual patient data or running standardized code to generate aggregate data estimates. For the primary analysis, we will pool data using two-stage meta-analysis methods. The meta-analyses will be updated as additional data accrue in each contributing study and as additional studies meet study-specific time or data accrual thresholds for sharing. At the time of publication, investigators of 25 studies, including more than 76,000 pregnancies, in 41 countries had agreed to share data for this analysis. Among the included studies, 12 have a contemporaneous comparison group of pregnancies without COVID-19, and four studies include a comparison group of non-pregnant women of reproductive age with COVID-19.

Results will be shared with key stakeholders, including the World Health Organization (WHO) Maternal, Newborn, Child, and Adolescent Health (MNCAH) Research Working Group. Data contributors will share results with local stakeholders. Scientific publications will be published in open-access journals on an ongoing basis.Cassava root rot disease is caused by a complex of soil-borne pathogens and has high economic impacts because it directly affects the tuberous roots, which are the main commercial product. This study aimed to evaluate cassava genotypes for resistance to root rot disease in a field with a previous history of high disease incidence. It also aimed to identify possible genomic regions associated with field resistance based on genome-wide association studies. A total of 148 genotypes from Embrapa Mandioca and Fruticultura were evaluated over two years, including improved materials and curated germplasms. Analysis of phenotypic data was conducted, as well as a genomic association analysis, based on the general linear model, mixed linear model, and fixed and random model circulating probability unification. The observed high disease index (ω) was directly correlated with genotype survival, affecting plant height, shoot yield, and fresh root yield. The genotypes were grouped into five clusters, which were classified according to level of root rot resistance (i.e., extremely susceptible, susceptible, moderately susceptible, moderately resistant, and resistant). The 10 genotypes with the best performance in the field were selected as potential progenitors for the development of segregating progenies. Estimates of genomic kinship between these genotypes ranged from -0.183 to 0.671. The genotypes BGM-1171 and BGM-1190 showed the lowest degree of kinship with the other selected sources of resistance. The genotypes BGM-0209, BGM-0398, and BGM-0659 showed negative kinship values with most elite varieties, while BGM-0659 presented negative kinship with all landraces. A genome-wide association analysis detected five significant single nucleotide polymorphisms related to defense mechanisms against biotic and abiotic stresses, with putative association with fresh root yield in soil infested with root rot pathogens. These findings can be utilized to develop molecular selection for root rot resistance in cassava.<br /><br /> The present study attempted to explore the effects of different tempos of piano music on heart rate and autonomous nervous system during the recovery period after high-intensity exercise. In addition, the study analyzed the influence of different tempos on the recovery period of athletes to devise methods for accelerating fatigue recovery through piano music.<br /><br /> A total of 57 college students majoring in physical education were selected as experimental subjects and were divided into three groups, namely Lento group (n=20), Moderato group (n=20), and Allegretto group (n=20; only 17 students completed the experiment).<br /><br /> Under the same high-intensity exercise regimen, the three groups did not differ significantly in the body composition, high-intensity exercise ability, and time-domain variation indices, namely heart rate (HR), heart rate variability index parameters (p &gt; .05). The time-domain variation analysis in the recovery period revealed significant differences in HR frequency domain indices among the groups exposed to different rhythms (p &lt; .05).<br /><br /> Moderate-tempo piano music was the most effective in facilitating HR and autonomic nervous system recovery during the recovery period.<br /><br />Moderate-tempo piano music was the most effective in facilitating HR and autonomic nervous system recovery during the recovery period.Intimate partner violence is one of the most challenging and demanding problems that the criminal justice system has to face. Given the severe consequences of intimate partner violence, it is imperative that intervention from the criminal justice system, regarding perpetrators, be effective to prevent further victimization and recurrences. In Portugal, it is up to the state prosecutor to decide which cases will be subject to a social reintegration program as a pretrial diversion program. This study aims to explore the variables that might influence the state prosecutor's decision-making process. We have examined 283 intimate partner violence cases in which provisional suspension of criminal proceedings was applied. The decision as to whether defendants should be referred for social reintegration program attendance (G1) or not (G2) was made by the state prosecutor. Differences between G1 and G2 were identified the victim's age, couple living in a current relationship, drug-addicted defendant, intimate partner violence child exposure. However, defendants' unemployment and drug abuse were the only two variables identified as a determinant for state prosecutor decisions. We believe that the effectiveness of state prosecution decision-making would benefit from (a) systematically taking into account all intimate partner violence risk factors; (b) an index or checklist detailing what science reveals useful in intimate partner violence offenders' social reintegration; (c) rehabilitation solutions based on the needs of each offender instead of a "one-size-fits-all" approach.
