Predicting Older Drivers\u27 Difficulties Using the Roadwise Review

There has been a substantial growth in research attempting to predict accidents and performance in older drivers. The Roadwise Review and the substantively identical Driver Health Inventory have been reported to provide a valid and cost-effective means of assessing crash risk in older communitydwelling adults. We administered the DHI to a community-dwelling sample of older (45 - 85 years) drivers. We also asked them to report on the difficulties they experienced while driving and on the frequency and type of crashes and moving violations the experienced in the previous two years. Results indicated on several of the tests there are substantial floor or ceiling effects, as well as barriers to usability and acceptance. Low inter-test correlations are consistent with the notion that different capacities are being indexed with the DHI. However, generally there were only low correlations between DHI performance and self-reported difficulties in driving, accidents or moving violations. While the DHI and Roadwise Review may well be valuable in providing older drivers with information on skills related to driving performance, in its current form it does not appear to be a useful tool in licensure or the prediction of driver risk

PCORnet Antibiotics and Childhood Growth Study: Process for Cohort Creation and Cohort Description

OBJECTIVES: The National Patient-Centered Clinical Research Network (PCORnet) supports observational and clinical research using health care data. The PCORnet Antibiotics and Childhood Growth Study is one of PCORnet’s inaugural observational studies. We sought to describe the processes used to integrate and analyze data from children across 35 participating institutions, the cohort characteristics, and prevalence of antibiotic use. METHODS:We included children in the cohort if they had at least one same-day height and weight measured in each of 3 age periods: 1) before 12 months, 2) 12 to 30 months, and 3) after 24 months. We distributed statistical queries that each institution ran on its local version of the PCORnet Common Data Model, with aggregate data returned for analysis. We defined overweight or obesity as age- and sex-specific body mass index ≥85th percentile, obesity ≥95th percentile, and severe obesity ≥120% of the 95th percentile. RESULTS: A total of 681,739 children met the cohort inclusion criteria, and participants were racially/ethnically diverse (24.9% black, 17.5% Hispanic). Before 24 months of age, 55.2% of children received at least one antibiotic prescription; 21.3% received a single antibiotic prescription; 14.3% received 4 or more; and 33.3% received a broad-spectrum antibiotic. Overweight and obesity prevalence was 27.6% at age 4 to(n = 362,044) and 36.2% at 9 to(n = 58,344). CONCLUSIONS: The PCORnet Antibiotics and Childhood Growth Study is a large national longitudinal observational study in a diverse population that will examine the relationship between early antibiotic use and subsequent growth patterns in children

Dbf4-dependent kinase (DDK)-mediated proteolysis of CENP-A prevents mislocalization of CENP-A in Saccharomyces cerevisiae

The evolutionarily conserved centromeric histone H3 variant (Cse4 in budding yeast, CENP-A in humans) is essential for faithful chromosome segregation. Mislocalization of CENP-A to non-centromeric chromatin contributes to chromosomal instability (CIN) in yeast, fly, and human cells and CENP-A is highly expressed and mislocalized in cancers. Defining mechanisms that prevent mislocalization of CENP-A is an area of active investigation. Ubiquitin-mediated proteolysis of overexpressed Cse4 (GALCSE4)byE3 ubiquitin ligases such as Psh1 prevents mislocalization of Cse4, and psh1D strains display synthetic dosage lethality (SDL) with GALCSE4. We previously performed a genome-wide screen and identified five alleles of CDC7 and DBF4 that encode the Dbf4-dependent kinase (DDK) complex, which regulates DNA replication initiation, among the top twelve hits that displayed SDL with GALCSE4. We determined that cdc7-7 strains exhibit defects in ubiquitin-mediated proteolysis of Cse4 and show mislocalization of Cse4. Mutation of MCM5 (mcm5-bob1) bypasses the requirement of Cdc7 for replication initiation and rescues replication defects in a cdc7-7 strain. We determined that mcm5-bob1 does not rescue the SDL and defects in proteolysis of GALCSE4 in a cdc7-7 strain, suggesting a DNA replication-independent role for Cdc7 in Cse4 proteolysis. The SDL phenotype, defects in ubiquitin-mediated proteolysis, and the mislocalization pattern of Cse4 in a cdc7-7 psh1D strain were similar to that of cdc7-7 and psh1D strains, suggesting that Cdc7 regulates Cse4 in a pathway that overlaps with Psh1. Our results define a DNA replication initiation-independent role of DDK as a regulator of Psh1-mediated proteolysis of Cse4 to prevent mislocalization of Cse4.Fil: Eisenstatt, Jessica R..

Skp, Cullin, F-box (SCF)-Met30 and SCF-Cdc4-Mediated Proteolysis of CENP-A Prevents Mislocalization of CENP-A for Chromosomal Stability in Budding Yeast

Restricting the localization of the histone H3 variant CENP-A (Cse4 in yeast, CID in flies) tocentromeres is essential for faithful chromosome segregation. Mislocalization of CENP-Aleads to chromosomal instability (CIN) in yeast, fly and human cells. Overexpression andmislocalization of CENP-A has been observed in many cancers and this correlates withincreased invasiveness and poor prognosis. Yet genes that regulate CENP-A levels andlocalization under physiological conditions have not been defined. In this study we used agenome-wide genetic screen to identify essential genes required for Cse4 homeostasis toprevent its mislocalization for chromosomal stability. We show that two Skp, Cullin, Fbox(SCF) ubiquitin ligases with the evolutionarily conserved F-box proteins Met30 andCdc4 interact and cooperatively regulate proteolysis of endogenous Cse4 and prevent itsmislocalization for faithful chromosome segregation under physiological conditions. Theinteraction of Met30 with Cdc4 is independent of the D domain, which is essential for theirhomodimerization and ubiquitination of other substrates. The requirement for both Cdc4and Met30 for ubiquitination is specifc for Cse4; and a common substrate for Cdc4 andMet30 has not previously been described. Met30 is necessary for the interaction betweenCdc4 and Cse4, and defects in this interaction lead to stabilization and mislocalization ofCse4, which in turn contributes to CIN. We provide the first direct link between Cse4 mislocalizationto defects in kinetochore structure and show that SCF-mediated proteolysis ofPLOS Genetics Cse4 is a major mechanism that prevents stable maintenance of Cse4 at non-centromericregions, thus ensuring faithful chromosome segregation. In summary, we have identifiedessential pathways that regulate cellular levels of endogenous Cse4 and shown that proteolysisof Cse4 by SCF-Met30/Cdc4 prevents mislocalization and CIN in unperturbed cells.Fil: Au, Wei-Chun.

Fração inspirada de oxigênio e mortalidade de pacientes ventilados mecanicamente em um hospital do interior da Amazônia: Inspired oxygen fraction and mortality of mechanically ventilated patients in a hospital in the interior of the Amazon

A Unidade de Terapia Intensiva (UTI) é um local que oferece atendimento para pacientes críticos, que frequentemente necessitam de ventilação mecânica invasiva (VMI) e Fração Inspirada de Oxigênio (FiO2) elevadas a fim de se evitar a hipóxia, muitos profissionais sabem sobre seus efeitos deletérios e por isso acreditam que a oxigenação suplementar seja inofensiva e consideram uma terapia benéfica, até mesmo quando não há necessidade de administração de oxigênio (O2). É necessário que a hipóxia seja tratada, entretanto deve ser feita de forma cautelosa para se evitar uma hiperóxia. O objetivo do estudo foi analisar a Pressão arterial de Oxigênio (PaO2), Fração Inspirada de Oxigênio (FiO2) durante a internação e verificar o desfecho clínico do paciente submetido a VMI (alta da UTI ou óbito). Trata-se de um estudo quantitativo descritivo, com abordagem prospectiva, realizado no Hospital Regional de Cacoal (HRC) no estado de Rondônia. A amostra foi formada por 19 pacientes internados na UTI e submetidos a VMI no período de março a maio de 2022. Observou-se que 57,9% dos pacientes estavam na faixa etária de 70 anos ou mais, eram predominantemente mulheres e 53,0% não apresentavam comorbidades. Quanto ao tempo de permanência na UTI, 68,4% permaneceram menos que 20 dias e em relação ao desfecho clínico 89,0% evoluíram para óbito. Observou-se que há um aumento da FiO2 na última gasometria dos que foram a óbito. Não foi identificado aumento na mortalidade associado a hiperóxia, descobrimos que quando a FiO2 se encontrava menor que 40% não era realizados ajustes na VMI

Andes, Bofedales, and the Communities of Huascarán National Park, Peru

Universidad Nacional Agraria La Molina. Escuela de Posgrado. Maestría en Producción AnimalMountain wetlands are abundant in the high elevations of the tropical Andes. Wetlands occupy ~11% of the total park area and are mostly found in the large mountain valleys. Wetlands occur up to 5000 m asl, but most occur between 4,000–4,700 m asl. The highest elevation wetlands are typically dominated by cushion plants, while lower elevation wetlands are more commonly occupied by graminoids. About 60% of all wetlands are peatlands and the remainder are mineral soil wet meadows. The peatlands are up to 11 m deep and 12,000 years old, storing an average of 2,101 Mg C ha-1, which is comparable to lowland tropical peatlands. Our work in Huascarán National Park in Peru is also showing the importance of wetlands in a coupled natural-human system. These wetlands and alpine landscapes are shaped in part by legacies of past human land use, including ancient pastoralism and farming, and are also affected by millions of downstream users dependent upon wetlands and glacier-fed streams for water and energy production. Biodiversity and endemism is high among taxonomic groups such as plants, birds, fish, amphibians and insects. Currently the tropical Andes are in ecological flux due to rapid land cover changes caused by both biophysical and socioeconomic drivers. In addition, the high Andes are experiencing warming and rapid glacial retreat that is resulting in hydroecological changes and socioeconomic changes to the traditional Andean societies that feed back to changes in wetland sustainability
