The value of banking relationships during a financial crisis: evidence from failures of Japanese banks
In this paper, we provide evidence on the value of banking relationships by examining the stock market valuation impact of three large bank failures in Japan in 1997 and 1998 on their clients and the clients of surviving banks. Bank failures are theorized to have adverse consequences for other firms in general and for customers of the failed institutions in particular. Firms that are customers of the failed institution may be adversely affected because they may lose an ongoing source of funding and need to incur the expense of search and providing financial and other information about themselves to new lenders. Firms that are not customers of the failed bank may be adversely affected because the failure may signal existing but yet unrecognized problems at other banks, ignite problems at other banks through spillover or contagion, or foretell adverse economic conditions for the economy in the region or nationwide. ; Unlike previous studies of this type, we examine the impact of bank failure announcements on the market valuation not only of the client firms of the failed banks but on all firms including the clients of surviving banks. We find that, as in previous studies, the market value of customers of the failed banks is adversely affected at the date of the failure announcements. Firms that have greater access to alternative sources of funding experience a less severe adverse impact from bank failure announcements. Similarly, clients of banks that are more profitable, better capitalized, and have lower loan loss reserves suffer less from the failure announcements. However, we also find that these effects are not significantly different from the effects experienced by all firms in the economy. That is, the bank failures represent "bad news" for all firms in the economy, not just for the customers of the failed banks.
The value of banking relationships during a financial crisis: evidence from failures of Japanese banks
In this paper, we provide evidence on the value of banking relationships by examining the stock market valuation impact of three large bank failures in Japan in 1997 and 1998 on their clients and the clients of surviving banks. Bank failures are theorized to have adverse consequences for other firms in general, and for customers of the failed institutions in particular. Firms that are customers of the failed institution may be adversely affected because, among other things, they may lose an ongoing source of funding and need to incur the expense of search and providing financial and other information about themselves to new lenders. Hence, severance of banking ties due to a bank failure can have adverse consequences for the clients of the failed bank. In addition, firms that are not customers of the failed bank may be adversely affected because the failure may signal existing but yet unrecognized problems at other banks, ignite problems at other banks through spillover or contagion, or foretell adverse economic conditions for the economy in the region or nationwide. ; Unlike previous studies of this type, we examine not only the impact of bank failure announcements on the market valuation of the client firms of the failed banks, but the impact of the announcements on all firms including the clients of surviving banks. By also examining the stock valuation of the failure announcements for firms that did not have relationships with the failed institutions, we can identify any differences in the effects on clients and non-clients of the failed banks. This is particularly important when the distress or failure announcements occur in the midst of an on-going financial crisis, and therefore, can have strong implications for the viability of surviving banks and their relationships with client firms. ; We find that, as in previous studies, the market value of customers of the failed banks is adversely affected at the date of the failure announcements. In addition, the effects are related to the financial characteristics of the client firms and their primary banks. Firms that have greater access to alternative sources of funding experience a less severe adverse impact from bank failure announcements. Similarly, clients of banks that are more profitable, better capitalized, and have lower loan loss reserves suffer less from the failure announcements. However, we also find that these effects are not significantly different from the effects experienced by all firms in the economy. That is, the bank failures represent "bad news" for all firms in the economy, not just for the customers of the failed banks.Financial crises - Japan ; Bank failures
The EXCEL Trial: The Interventionalists’ Perspective
Left main stem (LMS) disease is identified in up to 5% of diagnostic angiography cases, and is associated with significant morbidity and mortality due to the proportion of myocardium it subtends. In the past 10 years, there has been a significant change in the way we contemplate treating lesions in the LMS due to evolving experience and evidence in percutaneous coronary intervention (PCI) strategies and technologies. This has been reflected in recent changes in European and International guidance on managing patients with this lesion subset. Here, the authors provide an overview of the current literature regarding the management of LMS disease using PCI in light of new developments and emerging concepts in this field, specifically looking at the recent EXCEL trial
Extending Sustainable Irrigation Opportunities to Socially and Historically Disadvantaged Farmers in the Alabama Black Belt to Support Commercial-Level Production
This paper focuses on providing sustainable irrigation opportunities to socially and historically disadvantaged farmers (SHDFs). The ability to provide steady production capacity through the use of renewable energy sources and microirrigation is innovative, in that it demonstrated how to develop and utilize a sustainable irrigation system in both energy and water conservation. This venture is also innovative in that it sought to provide SHDFs with irrigation in a state in which irrigation in agriculture is minimal, while at the same time, offsetting the energy costs that normally accompany irrigation. Several farmers are profiled in their participation in the irrigation program. The lessons learned will provide a starting point for a more permanent research, educational, and outreach partnership between the United States Department of Agriculture (USDA) and SHDF clientele. This relationship will lead to further strengthening the relationships between Tuskegee University and both participating farmers and USDA agencies.

Optimal Brain MRI Protocol for New Neurological Complaint
Background/Purpose Patients with neurologic complaints are imaged with MRI protocols that may include many pulse sequences. It has not been documented which sequences are essential. We assessed the diagnostic accuracy of a limited number of sequences in patients with new neurologic complaints. Methods: 996 consecutive brain MRI studies from patients with new neurological complaints were divided into 2 groups. In group 1, reviewers used a 3-sequence set that included sagittal T1-weighted, axial T2-weighted fluid-attenuated inversion recovery, and axial diffusion-weighted images. Subsequently, another group of studies were reviewed using axial susceptibility-weighted images in addition to the 3 sequences. The reference standard was the study's official report. Discrepancies between the limited sequence review and the reference standard including Level I findings (that may require immediate change in patient management) were identified. Results: There were 84 major findings in 497 studies in group 1 with 21 not identified in the limited sequence evaluations: 12 enhancing lesions and 3 vascular abnormalities identified on MR angiography. The 3-sequence set did not reveal microhemorrhagic foci in 15 of 19 studies. There were 117 major findings in 499 studies in group 2 with 19 not identified on the 4-sequence set: 17 enhancing lesions and 2 vascular lesions identified on angiography. All 87 Level I findings were identified using limited sequence (56 acute infarcts, 16 hemorrhages, and 15 mass lesions). Conclusion: A 4-pulse sequence brain MRI study is sufficient to evaluate patients with a new neurological complaint except when contrast or angiography is indicated
Sleep During Pregnancy: The nuMoM2b Pregnancy and Sleep Duration and Continuity Study
Study Objectives:
To characterize sleep duration, timing and continuity measures in pregnancy and their association with key demographic variables.
Methods:
Multisite prospective cohort study. Women enrolled in the nuMoM2b study (nulliparous women with a singleton gestation) were recruited at the second study visit (16-21 weeks of gestation) to participate in the Sleep Duration and Continuity substudy. Women <18 years of age or with pregestational diabetes or chronic hypertension were excluded from participation. Women wore a wrist activity monitor and completed a sleep log for 7 consecutive days. Time in bed, sleep duration, fragmentation index, sleep efficiency, wake after sleep onset, and sleep midpoint were averaged across valid primary sleep periods for each participant.
Results:
Valid data were available from 782 women with mean age of 27.3 (5.5) years. Median sleep duration was 7.4 hours. Approximately 27.9% of women had a sleep duration of 9 hours. In multivariable models including age, race/ethnicity, body mass index, insurance status, and recent smoking history, sleep duration was significantly associated with race/ethnicity and insurance status, while time in bed was only associated with insurance status. Sleep continuity measures and sleep midpoint were significantly associated with all covariates in the model, with the exception of age for fragmentation index and smoking for wake after sleep onset.
Conclusions:
Our results demonstrate the relationship between sleep and important demographic characteristics during pregnancy

The Massachusetts General Hospital Acute Stroke Imaging Algorithm: An Experience and Evidence Based Approach
The Massachusetts General Hospital Neuroradiology Division employed an experience and evidence based approach to develop a neuroimaging algorithm to best select patients with severe ischemic strokes caused by anterior circulation occlusions (ACOs) for intravenous tissue plasminogen activator and endovascular treatment. Methods found to be of value included the National Institutes of Health Stroke Scale (NIHSS), non-contrast CT, CT angiography (CTA) and diffusion MRI. Perfusion imaging by CT and MRI were found to be unnecessary for safe and effective triage of patients with severe ACOs. An algorithm was adopted that includes: non-contrast CT to identify hemorrhage and large hypodensity followed by CTA to identify the ACO; diffusion MRI to estimate the core infarct; and NIHSS in conjunction with diffusion data to estimate the clinical penumbra
Model Systems to Study the Chronic, Polymicrobial Infections in Cystic Fibrosis: Current Approaches and Exploring Future Directions
A recent workshop titled “Developing Models to Study Polymicrobial Infections,” sponsored by the Dartmouth Cystic Fibrosis Center (DartCF), explored the development of new models to study the polymicrobial infections associated with the airways of persons with cystic fibrosis (CF). The workshop gathered 351 investigators over two virtual sessions. Here, we present the findings of this workshop, summarize some of the challenges involved with developing such models, and suggest three frameworks to tackle this complex problem. The frameworks proposed here, we believe, could be generally useful in developing new model systems for other infectious diseases. Developing and validating new approaches to study the complex polymicrobial communities in the CF airway could open windows to new therapeutics to treat these recalcitrant infections, as well as uncovering organizing principles applicable to chronic polymicrobial infections more generally
Objectively measured short sleep duration and later sleep midpoint in pregnancy are associated with a higher risk of gestational diabetes
BACKGROUND:
Experimental and epidemiologic data suggest that among nonpregnant adults, sleep duration may be an important risk factor for chronic disease. Although pregnant women commonly report poor sleep, few studies objectively evaluated the quality of sleep in pregnancy or explored the relationship between sleep disturbances and maternal and perinatal outcomes.
OBJECTIVE:
Our objective was to examine the relationship between objectively assessed sleep duration, timing, and continuity (measured via wrist actigraphy) and maternal cardiovascular and metabolic morbidity specific to pregnancy.
STUDY DESIGN:
This was a prospective cohort study of nulliparous women. Women were recruited between 16 0/7 and 21 6/7 weeks' gestation. They were asked to wear a wrist actigraphy monitor and complete a daily sleep log for a period of 7 consecutive days. The primary sleep exposure variables were the averages of the following over the total valid nights (minimum 5, maximum 7 nights): short sleep duration during the primary sleep period (5 am), and top quartile of minutes of wake time after sleep onset and sleep fragmentation index. The primary outcomes of interest were a composite of hypertensive disorders of pregnancy (mild, severe, or superimposed preeclampsia; eclampsia; or antepartum gestational hypertension) and gestational diabetes mellitus. We used χ2 tests to assess associations between sleep variables and categorical baseline characteristics. Crude odds ratios and 95% confidence intervals were estimated from univariate logistic regression models to characterize the magnitude of the relationship between sleep characteristics and hypertensive disorders of pregnancy and gestational diabetes. For associations significant in univariate analysis, multiple logistic regression was used to explore further the association of sleep characteristics with pregnancy outcomes.
RESULTS:
In all, 901 eligible women consented to participate; 782 submitted valid actigraphy studies. Short sleep duration and a later sleep midpoint were associated with an increased risk of gestational diabetes (odds ratio, 2.24; 95% confidence interval, 1.11-4.53; and odds ratio, 2.58; 95% confidence interval, 1.24-5.36, respectively) but not of hypertensive disorders. A model with both sleep duration and sleep midpoint as well as their interaction term revealed that while there was no significant interaction between these exposures, the main effects of both short sleep duration and later sleep midpoint with gestational diabetes remained significant (adjusted odds ratio, 2.06; 95% confidence interval, 1.01-4.19; and adjusted odds ratio, 2.37; 95% confidence interval, 1.13-4.97, respectively). Additionally, after adjusting separately for age, body mass index, and race/ethnicity, both short sleep duration and later sleep midpoint remained associated with gestational diabetes. No associations were demonstrated between the sleep quality measures (wake after sleep onset, sleep fragmentation) and hypertensive disorders or gestational diabetes.
CONCLUSION:
Our results demonstrate a relationship between short sleep duration and later sleep midpoint with gestational diabetes. Our data suggest independent contributions of these 2 sleep characteristics to the risk for gestational diabetes in nulliparous women
