Volcker Rule

Banks use trading as a vehicle to take risk. Using unique high-frequency regulatory data, we estimate the sensitivity of weekly bank trading profits to aggregate equity, fixed-income, credit, currency and commodity risk factors. Our estimates imply that U.S. banks had large trading exposures to equity market risk before the Volcker Rule, which they curtailed afterwards. They also have exposures to credit and currency risk. The results hold up in a quasi-natural experimental design that exploits the phased-in introduction of reporting requirements to address identification. Heterogeneity and placebo tests further corroborate the results. Counterfactual stress-test analyses quantify the financial stability implications.

Background: the clustering of metabolic syndrome (MetS) risk factors is becoming more prevalent in children, leading to the development of type 2 diabetes (T2D) and cardiovascular diseases in early adulthood. The impact of MetS risk factors on cardiac autonomic modulation (CAM) or vice versa has been noted to track from childhood to pre-adolescence and adolescence. Understating associations in this age group may help to improve the clinical outcomes of the MetS, even when MetS symptoms are not visible. Potential damage from each individual MetS component and the ability to predict early cardiac damage or upcoming cardiovascular events is very important. Therefore, the present systematic review and meta-analysis investigated the associations between CAM and MetS risk factors individually to verify which of the MetS risk components were significantly correlated with heart rate variability (HRV) indices before or at the onset of the MetS among young people. The purpose of this review was to outline the importance of potentially screening HRV indices in young people even with only one MetS risk factor, as a pre-indicator for early cardiovascular risk stratification. Methods: cross-sectional studies that examined the relationship of MetS risk factors with HRV indices were searched using four databases including PubMed, the Cochrane clinical trials library, Medline and the Web of Science. Correlation coefficients with 95% confidence intervals (95% CI), and random effects meta-analyses of the association between MetS risk factors with HRV indices were performed. Results: out of 14 cross-sectional studies and one case-control study, 8 studies (10 data sets) provided association data for the meta-analysis. Our results indicated significant positive correlations for systolic blood pressure (SBP) (correlation coefficient 0.13 (95%CI: 0.06; 0.19), I2 = 47.26%) and diastolic blood pressure (DBP) (correlation coefficient 0.09 (95%CI: −0.01; 0.18), I2 = 0%) with a Low Frequency/High Frequency ratio (LF/HF). Significant negative correlations for waist circumference (WC) (correlation coefficient −0.12 (95%CI: −0.19; −0.04), I2 = 51.50%), Triglycerides (TGs) (correlation coefficient −0.09 (95%CI: −0.15; −0.02), I2 = 0%) and ≥2 MetS risk factors (correlation coefficient −0.10 (95%CI: −0.16; −0.03), I2 = 0%); with high frequency (HF) were revealed. Significant positive correlations for high density lipoprotein (HDL) (correlation coefficient 0.08 (95%CI: 0.05; 0.11), I2 = 0%) and significant negative correlations of ≥2 MetS risk (correlation coefficient −0.04 (95%CI: −0.12; 0.03), I2 = 0.0%) with low frequency (LF) were revealed. Significant negative correlations for TGs (correlation coefficient −0.09 (95%CI: −0.23; 0.05), I2 = 2.01%) with a mean square root of the sum of differences between mean time between two successive intervals (rMSSD) and significant positive correlation of HDL (correlation coefficient 0.09 (95%CI: −0.01; 0.19), I2 = 0.33%) with standard deviation of the time between two successive intervals (SDNN) were also revealed. An Egger’s test indicated that there was no obvious publication bias for any of the above relationships except for TGs and rMSSD. The significance level stipulated for the meta-analysis was p < 0.05. Conclusions: lipid profiles (HDL and TGs), WC and BP were associated with CAM in young people up to the age of 19 years. The use of HRV indices to predict future MetS risk, and relationships with individual risk factors including HDL, BP, WC and TGs, were established. Future studies related to young people (up to the age of 19 years) are recommended to explore the associations reported here further.

Introduction: We sought to (1) classify patients who underwent stress echocardiography in an emergency department observation unit based on their pretest probabilities of obstructive CAD using the Diamond-Forrester criterion, (2) to compare observed versus expected frequencies of obstructive CAD based on the Diamond-Forrester risk categories of low (<25%), intermediate (25-75%), and high (>75%) pretest probability of disease, and (3) to test the association of traditional cardiovascular risk factors (age, gender, hypertension, diabetes, high cholesterol, and smoking) with obstructive CAD. METHODS: Retrospective review of the electronic medical record for patients who presented to the emergency department with chest pain and underwent observation followed by stress echocardiography between the period January 1, 2012 to December 31, 2012. Patients were classified as low, intermediate, or high risk for obstructive CAD using the Diamond-Forrester criterion. Main outcome measures were stress echocardiography results as well as receipt of cardiac catheterization and results. RESULTS: A total of 504 patients were included in the final analysis. Overall, 4.8% had a positive stress test and only 1.2% had angiographic evidence of obstructive CAD. In each category of risk, the observed frequency of obstructive CAD was significantly lower than expected. Having a high pretest probability as defined by the Diamond-Forrester criterion was significantly associated with obstructive CAD. Age, gender, diabetes, hypertension, high cholesterol, and smoking were not independently associated with evidence of obstructive CAD; nor were any composites of these risk factors. CONCLUSIONS: The traditional Diamond-Forrester criterion significantly overestimates the probability of obstructive CAD in ED observation unit patients. Reliance on the Diamond-Forrester criterion and other traditional risk factors associated with obstructive CAD in the outpatient setting could lead to faulty Bayesian reasoning, overuse of non-invasive imaging, and improper interpretation of test results in an ED population of low-risk chest pain patients. Further work is required to determine an optimal risk-assessment strategy for this patient population.

SUMMARYIn this study, Coxiella burnetii seroprevalence was assessed for dairy and non-dairy sheep farm residents in The Netherlands for 2009–2010. Risk factors for seropositivity were identified for non-dairy sheep farm residents. Participants completed farm-based and individual questionnaires. In addition, participants were tested for IgG and IgM C. burnetii antibodies using immunofluorescent assay. Risk factors were identified by univariate, multivariate logistic regression, and multivariate multilevel analyses. In dairy and non-dairy sheep farm residents, seroprevalence was 66·7% and 51·3%, respectively. Significant risk factors were cattle contact, high goat density near the farm, sheep supplied from two provinces, high frequency of refreshing stable bedding, farm started before 1990 and presence of the Blessumer breed. Most risk factors indicate current or past goat and cattle exposure, with limited factors involving sheep. Subtyping human, cattle, goat, and sheep C. burnetii strains might elucidate their role in the infection risk of sheep farm residents.

Angiography of patients with typical chest pain reveals normal epicardial coronary arteries in about 15-20%. ECG changes suggestive of myocardial ischemia during exercise also can be demonstrated in this subset of the patients. Total 58 patients (42 females) with mean age 42±7 years who were undergoing coronary angiogram in the Department of Cardiology, University Cardiac Center, Bangabandhu Sheikh Mujib Medical University, Dhaka, Bangladesh from January 2005 to December 2009 were evaluated. The patients were recruited on the basis of presence of history of chest pain, with normal resting ECG and ischemia like ECG changes during exercise stress test. 32.8% patients had hypertension and 15.5% were diabetics, 19.0% had dyslipidemia and 6.9% had family history of ischemic heart disease. All the patients were having positive exercise stress test. Angiographic findings showed luminal irregularities in 29.3% patients, 15.5% patients had luminal stenosis less than 30% and rest had normal coronary angiogram. Follow up of the patients after one and six months of angiogram was done. After one month 63.8% patients remained symptomatic and after six months 63.3% patients remained symptomatic despite maximum medical management. The pathophysiology and appropriate management of this subset of the patients still remained a challenge for physicians. Optimum management of cardiovascular risk factors is very important issue in this group of patients.Key words: Angiography; Epicardial coronary arteries; Exercise stress test; Cardiovascular risk factors.

BACKGROUND: Pro12Ala (rs1801282) is a common polymorphism of the human PPAR-γ gene. Studies have demonstrated conflicting results about its association with T2DM worldwide. There are no reports about such possible association among Iraqi people. OBJECTIVES:  This study aims at finding out whether having the mutant allele (Ala12) might be associated with T2DM among Iraqi people.METHODS: One hundred and ninety-two Arabic Iraqi adult subjects (97 with T2DM and 95 controls) were genotyped using PCR- RFLP. Clinical, anthropometrical and biochemical variables were compared regarding the Pro12Ala genotypes.RESULTS: About 5.67% of people with diabetes were carriers of the (Ala12) allele versus 9.47% of controls. Allelic and genotypic frequencies were not statistically different among diabetics and controls [(c2= 1.99, p= 0.16) and (c2= 2.17, p= 0.14)]. Age, BMI and smoking- but not Pro12Ala - were independent risk factors for T2DM in our subjects. Pro12Ala was not associated with T2DM (Odd's ratio 0.55, 95% CI 0.23- 1.32, p= 0.14).CONCLUSIONS: Our study revealed a relatively high frequency of the Ala12 allele among Arabic Iraqis. These frequencies did not significantly differ between diabetics and controls indicating the absence of association of Pro12Ala with T2DM among Iraqis.

PurposeThis research aimed to explore the prevalence of musculoskeletal disorders (MSDs) and related factors among subcontracted cleaners in a teaching hospital in Thailand.Design/methodology/approachA cross-sectional study was conducted of 393 subcontracted cleaners in a teaching hospital, from May to June 2020. Face-to-face interviews were carried out using a standard questionnaire, consisting of four parts: (1) participant characteristics, (2) stress test, (3) work characteristics and (4) standardized Nordic questionnaire, Thai version, for MSDs outcome. Multiple logistic regression analyses were performed to determine the association between MSDs and related factors.FindingsThe prevalence of MSDs was 81.9%, involving mostly the lower back (57.7%), followed by the shoulder (52.6%). Factors significantly associated with MSDs were as follows: male gender (OR = 3.06, 95% CI [1.19, 7.87]), severe stress (OR = 2.72, 95% CI [1.13, 6.54]), history of injuries (OR = 4.37, 95% CI [1.27, 15.11]), mopping posture (OR = 2.81, 95% CI [1.43, 5.50]) and task duration (OR = 1.90, 95% CI [1.01, 3.57] for 2–4 h and OR = 3.39, 95% CI [1.17, 9.86] for more than 4 h). Sick leave due to MSDs was associated with history of injuries, Thai nationality and having another part-time job.Originality/valueThe study findings about MSDs in terms of prevalence and related factors contributed to limited pool of the knowledge among subcontracted hospital cleaners in Thailand and middle-income country settings. With growing popularity in outsourcing cleaning services among hospitals in these countries, the study findings could raise a concern and inform policymakers and hospital administrators the importance of the magnitude and risk factors for MSDs necessitating design of preventive strategies.

To study morphological features of the placenta in women in labor, pregnancy which complicated by preeclampsia we studied 26 placentae, of which 17 were from pregnant women with mild to moderate preeclampsia (basic group) and 9 from healthy women (control group). Histologically the study was conducted with methodically recommendations of T.D. Zadorozhnaya et al. for light microscopy. During the study of morphological features of the placenta in women in labor with preeclampsia were installed morphological changes in the placenta, which reflect a tendency to develop compensatory-adaptive reactions following their stress and exhaustion, which is a sign of placental insufficiency. Received data allow claiming a high frequency of development placental insufficiency in pregnant women with risk factors such as chronic salpingo-oophoritis, anemia, late preeclampsia, and inflammation diseases kidney.

Background: Evidence supports that peripheral vasoconstriction during mental stress predicts mental stress induced ischemia (MSIMI). However, whether a dose response relationship exists with ischemia severity has not been evaluated; additionally, whether peripheral vascular function during the recovery phase is also related to MSIMI is not known. Hypothesis: We hypothesized that increased digital microvascular constriction during both mental stress and recovery are predictive of increased severity of mental stress ischemia. Methods: We evaluated 204 patients with stable CAD with high quality vascular data using a standardized mental stress test using a public speaking task. Peripheral artery tonometry (PAT) (Itamar Inc) was used to assess digital microvascular tone. Vasoconstriction was calculated as the ratio of pulse wave amplitude during speech/recovery and the last 3 minutes of baseline, with lower ratio indicating more vasoconstriction. 99mTc sestamibi myocardial perfusion imaging was performed at rest and with mental stress. A summed difference score (SDS) quantifying severity of reversible perfusion defects (inducible ischemia) comparing rest and stress images was computed using a standard 17-segment model. Four categories of increasing severity were based on cut points of 0, 3, and 6. Results: The mean (SD) age was 64 (8), 16% were women, and 28% were African American. Each category of increase in ischemia severity was associated with a 10% (p=0.04) decrease in speech PAT ratio (Figure) and 11% (p=0.02) decrease in recovery PAT ratio. After multivariable adjustment for sociodemographics, traditional risk factors, medical history, medication use, and psychological risk factors, the associations persisted, with B=-11%, p=0.02 for speech PAT ratio, and B=-8%, p=0.04 for recovery ratio. Conclusion: Peripheral vasoconstriction during mental stress speech as well as recovery predicts MSI severity in a dose-response relationship.
