Determinants of the Closing Probability of Residential Mortgage Applications
After allowing applicants to "lock" the interest rate, mortgage originators are concerned with protecting themselves from adverse outcomes due to interest-rate changes. One may expect applicants would strive to close applications when rates rose, while letting themselves fall out when rates decline. Our results show that applicant response to interest-rate changes and volatility are modest. The most important predictor of closing probability is the length of the lock period, with shorter locks being more likely to close. Applications for single-family are more likely to close than are those for multiunit dwellings. Applications for owner-occupied properties are more likely to close than are those for investment properties. Applicant characteristics such as loan affordability, education and age have a small influence on closing rate. Gender has an effect for some loan programs, and marital status appears to be irrelevant. Discount points affect refinance mortgages more than purchase mortgages. Conventional applications are more likely to close than FHA and VA, and applications for refinance, in general, are less likely to close. Results are mixed for ARM and fifteen-year applications, as well as for whether it was the original application, or a relock.
The Influence of Race in Residential Mortgage Closings
This study examines how applicants identified as Asian, Black or Hispanic differ in mortgage closing outcomes compared to the remaining applicants. First, the findings show that minority applicants are somewhat less likely to close a loan for purchase, but equally likely to close a loan for refinance. A more important question this study addresses is whether minority borrowers have less efficient closing outcomes. The findings show no statistical difference between minority and non-minority applicants. This indicates that originators do not demonstrate a ‘‘taste for discrimination’’ by basing their loan approval for minorities on whether the loan can be profitably sold.
‘Hearts and minds’: association, causation and implication of cognitive impairment in heart failure
The clinical syndrome of heart failure is one of the leading causes of hospitalisation and mortality in older adults. An association between cognitive impairment and heart failure is well described but our understanding of the relationship between the two conditions remains limited. In this review we provide a synthesis of available evidence, focussing on epidemiology, the potential pathogenesis, and treatment implications of cognitive decline in heart failure. Most evidence available relates to heart failure with reduced ejection fraction and the syndromes of chronic cognitive decline or dementia. These conditions are only part of a complex heart failure-cognition paradigm. Associations between cognition and heart failure with preserved ejection fraction and between acute delirium and heart failure also seem evident and where data are available we will discuss these syndromes. Many questions remain unanswered regarding heart failure and cognition. Much of the observational evidence on the association is confounded by study design, comorbidity and insensitive cognitive assessment tools. If a causal link exists, there are several potential pathophysiological explanations. Plausible underlying mechanisms relating to cerebral hypoperfusion or occult cerebrovascular disease have been described and it seems likely that these may coexist and exert synergistic effects. Despite the prevalence of the two conditions, when cognitive impairment coexists with heart failure there is no specific guidance on treatment. Institution of evidence-based heart failure therapies that reduce mortality and hospitalisations seems intuitive and there is no signal that these interventions have an adverse effect on cognition. However, cognitive impairment will present a further barrier to the often complex medication self-management that is required in contemporary heart failure treatment
Dementia-related adverse events in PARADIGM-HF and other trials in heart failure with reduced ejection fraction.
Aims:
Inhibition of neprilysin, an enzyme degrading natriuretic and other vasoactive peptides, is beneficial in heart failure with reduced ejection fraction (HFrEF), as shown in PARADIGM-HF which compared the angiotensin receptor–neprilysin inhibitor (ARNI) sacubitril/valsartan with enalapril. As neprilysin is also one of many enzymes clearing amyloid-β peptides from the brain, there is a theoretical concern about the long-term effects of sacubitril/valsartan on cognition. Therefore, we have examined dementia-related adverse effects (AEs) in PARADIGM-HF and placed these findings in the context of other recently conducted HFrEF trials.
Methods and results:
In PARADIGM-HF, patients with symptomatic HFrEF were randomized to sacubitril/valsartan 97/103 mg b.i.d. or enalapril 10 mg b.i.d. in a 1:1 ratio. We systematically searched AE reports, coded using the Medical Dictionary for Regulatory Activities (MedDRA), using Standardized MedDRA Queries (SMQs) with ‘broad’ and ‘narrow’ preferred terms related to dementia. In PARADIGM-HF, 8399 patients aged 18–96 years were randomized and followed for a median of 2.25 years (up to 4.3 years). The narrow SMQ search identified 27 dementia-related AEs: 15 (0.36%) on enalapril and 12 (0.29%) on sacubitril/valsartan [hazard ratio (HR) 0.73, 95% confidence interval (CI) 0.33–1.59]. The broad search identified 97 (2.30%) and 104 (2.48%) AEs (HR 1.01, 95% CI 0.75–1.37), respectively. The rates of dementia-related AEs in both treatment groups in PARADIGM-HF were similar to those in three other recent trials in HFrEF.
Conclusion:
We found no evidence that sacubitril/valsartan, compared with enalapril, increased dementia-related AEs, although longer follow-up may be necessary to detect such a signal and more sensitive tools are needed to detect lesser degrees of cognitive impairment. Further studies to address this question are warranted

China’s Emergence as a Global Recycling Hub – What Does it Mean for Circular Economy Approaches Elsewhere?
This Evidence Report investigates how China’s rise as a global recycling hub affects other countries’ prospects for moving towards a circular economy. This question has received little, if any, attention in the burgeoning literature on sustainability. There is substantial literature on global resource depletion, on the need to overcome the throwaway economy and on national and local attempts to move towards a circular economy. There is, however, little analysis of how the global trade in recycled materials, which is increasingly dominated by China, affects other countries’ attempts to build a circular economy.UK Department for International Developmen
Septin Stability and Recycling during Dynamic Structural Transitions in Cell Division and Development
SummarySeptins are conserved proteins found in hetero-oligomeric complexes that are incorporated into distinct structures during cell division and differentiation; yeast septins Cdc3, Cdc10, Cdc11, and Cdc12 form hetero-octamers and polymerize into filaments, which form a “collar” at the mother-bud neck [1]. Posttranslational modifications, nucleotide binding, and protein-protein and protein-lipid interactions influence assembly and disassembly of septin structures [2], but whether individual septins are used repeatedly to build higher-order assemblies was not known. We used fluorescence-based pulse-chase methods to visualize the fate of pre-existing (old) and newly synthesized (new) molecules of two septins, Cdc10 and Cdc12. They were recycled through multiple mitotic divisions, and old and new molecules were incorporated indistinguishably into the collar. Likewise, old and new subunits intermixed within hetero-octamers, indicating that exchange occurs at this organizational level. Remarkably, in meiosis, Cdc10 made during vegetative growth was reutilized to build sporulation-specific structures and reused again during spore germination for budding and during subsequent mitotic divisions. Although Cdc12 also persisted during sporulation, it was excluded from septin structures and replaced by another subunit, Spr3; only new Cdc12 populated the collar of germinating spores. Thus, mechanisms governing septin incorporation are specific to each subunit and to the developmental state of the cell
Septins: molecular partitioning and the generation of cellular asymmetry
During division, certain cellular contents can be distributed unequally; daughter cells with different fates have different needs. Septins are proteins that participate in the establishment and maintenance of asymmetry during cell morphogenesis, thereby contributing to the unequal partitioning of cellular contents during division. The septins themselves provide a paradigm for studying how elaborate multi-component structures are assembled, dynamically modified, and segregated through each cell division cycle and during development. Here we review our current understanding of the supramolecular organization of septins, the function of septins in cellular compartmentalization, and the mechanisms that control assembly, dynamics, and inheritance of higher-order septin structures, with particular emphasis on recent findings made in budding yeast (Saccharomyces cerevisiae)
