•We model long term US Treasury, agency, corporate and municipal bond yields.•Our ARDL models fully explain the US bond yield conundrum of 2004–2007.•Domestic and foreign demand variables were the ...main yield depressing factors.•There are strong linkages between the Treasury yield and non-Treasury bond yields.•Our results support the search for yield hypothesis as a reason for the CDO growth.
Although the federal funds rate started rising from mid-2004 US long term rates continued to fall. A likely contributory factor to this ‘conundrum’ was the contemporaneous increase in US bond demand. Using ARDL based models, which accommodate structural breaks, this paper estimates the impact of foreign and domestic demand on AAA rated US bond yields in the ‘conundrum’ period. This impact is shown to have been everywhere significantly negative. The fact that our model fully explains the ‘bond yield conundrum’ gives support to the hypothesis that the US CDO market was rapidly expanded before 2007 chiefly to absorb the overspill of global demand for safe assets. Moreover, our models demonstrate that there are strong linkages between the 10-year Treasury yield and the long term yields of AAA rated non-Treasury bonds.
A seroprevalence study can estimate the percentage of people with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies in the general population; however, most existing reports ...have used a convenience sample, which may bias their estimates.
We sought a representative sample of Connecticut residents, ages ≥18 years and residing in noncongregate settings, who completed a survey between June 4 and June 23, 2020, and underwent serology testing for SARS-CoV-2-specific immunoglobulin G (IgG) antibodies between June 10 and July 29, 2020. We also oversampled non-Hispanic black and Hispanic subpopulations. We estimated the seroprevalence of SARS-CoV-2-specific IgG antibodies and the prevalence of symptomatic illness and self-reported adherence to risk-mitigation behaviors among this population.
Of the 567 respondents (mean age 50 ± 17 years; 53% women; 75% non-Hispanic white individuals) included at the state level, 23 respondents tested positive for SARS-CoV-2-specific antibodies, resulting in weighted seroprevalence of 4.0 (90% confidence interval CI 2.0-6.0). The weighted seroprevalence for the oversampled non-Hispanic black and Hispanic populations was 6.4% (90% CI 0.9-11.9) and 19.9% (90% CI 13.2-26.6), respectively. The majority of respondents at the state level reported following risk-mitigation behaviors: 73% avoided public places, 75% avoided gatherings of families or friends, and 97% wore a facemask, at least part of the time.
These estimates indicate that the vast majority of people in Connecticut lack antibodies against SARS-CoV-2, and there is variation by race and ethnicity. There is a need for continued adherence to risk-mitigation behaviors among Connecticut residents to prevent resurgence of COVID-19 in this region.
► Accounting for country specific effects in the models of international bank ratings substantially improves their predictive ability for all statistical methods considered. ► Support vector machines ...produce considerably better predictions of international bank ratings than ordered choice models due to their ability to estimate a large number of country indicator variables unrestrictedly and simultaneously. ► We suggest a method whereby support vector machines can be used to identify which variables are significant determinants of international bank ratings, although we argue that ordered choice models are better suited for this purpose.
We compare the ability of ordered choice models and support vector machines to model and predict international bank ratings. Although support vector machines can identify significant determinants we argue that ordered choice models are more reliable for this. Our findings suggest that ratings reflect a bank’s financial position, the timing of rating assignment and a bank’s country of origin. Accounting for country effects substantially improves predictive performance. We find that support vector machines can produce considerably better predictions of international bank ratings than ordered choice models due to the formers ability to estimate a large number of country dummies unrestrictedly.
Introduction: The management of CLL patients historically utilized FD chemoimmunotherapy (CIT), including fludarabine, cyclophosphamide and rituximab (FCR), or bendamustine and rituximab (BR). That ...changed with the introduction of Bruton Tyrosine Kinase inhibitors (BTKi) as an option for oral targeted monotherapy delivered continuously until disease progression or intolerance. Recently, novel combinations that include a B-cell lymphoma 2 inhibitor (BCL2i), such as venetoclax, have been developed as FD therapy. In addition, though not FDA approved, MRD assessment is emerging as a potential tool to guide FD therapy. Understanding the patient and their caregiver perspectives on FD and MRD is critical to providing the best care.
Methods: CLL Society developed a web-based survey instrument of multiple-choice questions to assess patient and caregiver awareness, understanding, and preferences with MRD and FD therapies, where FD referred to both time and MRD guided limited duration therapies. Patients and caregivers were invited to participate via message boards, CLL Society's website, email, and online communities.
Results: A total of 607 (96%) self-identified US patients and 36 (5%) caregivers, who answered on behalf of patients in their care, completed the survey between 31/AUG/2020 and 31/JAN/2021. The mean patient age was 64 (range, 30-90) years, 54% were female, 169 patients (27%) treatment-naïve, 239 (38%) with one line of prior therapy, and 214 (34%) with two or more. Targeted agents (e.g., venetoclax, ibrutinib, acalabrutinib, idelalisib, and duvelisib) had been used by 401 (64%). FD use with some novel therapies was known of by 565 (90%) patients, while 588 (93%) knew some were used as continuous daily treatment until disease progression or intolerance. If effectiveness and side effects were assumed similar, 485 (77%) preferred FD, and 398 (63%) wanted that finite treatment to be guided by MRD status. Only 42 (7%) preferred continuous therapy until disease progression or intolerance. The chance for continued remission while off treatment was ranked as a very important potential benefit after stopping a FD therapy by 581 (92%) patients. When considering therapy, 589 (93%), 575 (91%), 447 (71%), 415 (66%), 302 (48%), and 288 (46%) rated having overall survival, having future therapeutic options, avoiding chemotherapy, the ability to reach undetectable (u)MRD, minimal lab and office visits, and FD therapy as very important, respectively (Fig. 1). Being tested for MRD at least once was reported by 215 (34%), while 327 (52%) had not been tested, and 88 (14%) were unsure. There were 562 (89%) who were somewhat or very familiar with the term MRD, while 450 (71%) were confident of understanding what MRD testing measures, and 446 (70%) understood its role in CLL. Only 225 (36%) stated they understood different testing methods. While self-rated understanding of the indications for MRD testing was relatively high, some wanted testing done when not clinically indicated, such as when there was persistent CLL by routine laboratory findings, or at the time of diagnosis (Fig. 2). Respondents were mixed in their stated understanding as to which therapies could result in uMRD, with 241 (38%), 197 (32%), and 195 (32%) not knowing if CIT, BCL2i, and BTKi, could lead to uMRD, respectively. Two hundred and sixty-five (42%), 84 (13%), and 57 (9%) believed it was possible for most on a BCL2i, BTKi, or CIT to achieve uMRD, respectively (Fig. 3). If patients had evidence of MRD at the end of treatment, 365 (58%) would request frequent monitoring but would make no immediate treatment decisions based on MRD status, 279 (44%) were unsure, and only 88 (14%) would want further treatment immediately.
Conclusions: The results from this patient-based study reveal a high awareness of FD therapies and MRD testing, as well as a clear preference for FD among internet-active patients and caregivers. However, there are gaps in the knowledge base, thus significant educational opportunities. Limitations included the opt-in sample where the survey results may not be projectable to the total CLL population. Moreover, the survey was not designed to assess preferences if either FD or continuous therapy offered improved outcomes. Nonetheless, as the potential role of MRD and FD therapy grows in CLL it will be incumbent on clinicians to ensure patients are well informed and engaged to help them better share therapeutic decisions.

Empathy is a critical component of social work practice, yet research has indicated that health professionals often express negative attitudes toward people who abuse substances. The current study ...examines levels of empathy and attitudes of social work students, clinical social workers and practicing nurses. Rates of empathy were lower than expected. The findings suggest that using tools such as SBIRT may be beneficial in terms of contributing to job satisfaction and well-being of nurses and social workers in the field.
