Prevalence and Degree of Breast Arterial Calcifications on Mammography: A Cross-sectional Analysis

Objectives: The purpose of this study is to establish a database including prevalence and degree of breast arterial calcifications (BAC) in our population of women presenting for mammography. Materials and Methods: The mammograms of 1786 women over the age of 40 years were examined for the presence and degree of BAC. Statistical analysis was performed to correlate patient's age and ethnic origin with the presence and degree of BAC. Results: There was statistically significant and strong correlation between the patient's age and presence of BAC. There was also a less strong yet statistically significant correlation between patient age and degree of BAC. Regression analysis showed the likelihood of BAC at various ages. The prevalence of BAC is only 2% of women under 50 years of age; the prevalence of Grade 2-3 BAC is only 1% in women under 60 years of age. Conclusion: There is a predictable increase with age in both prevalence and degree of BAC in women. The presence of high degree BAC in women under 60 years of age or any BAC in women under 50 years of age is unusual.

ObjectivesWe performed a cross-sectional analysis of data from the nationwide Korea National Health and Nutrition Examination Survey to evaluate the association between obesity and chronic rhinosinusitis with nasal polyps (CRSwNP) or without nasal polyp (CRSsNP).DesignRetrospective cross-sectional analysis of health survey data.SettingVoluntary survey of representative South Korean populations.ParticipantsIn total, 32 384 individuals aged 19 years or older with available data on CRS and obesity were included.Primary and secondary outcome measuresDiagnosis of CRSwNP or CRSsNP was performed by trained otolaryngologists through sinus endoscopy and surveys of medical history. General and central obesity was diagnosed using body mass index (BMI) and waist circumference (WC), respectively.MethodsA multivariate logistic regression analysis was used to clarify the association between CRSwNP or CRSsNP and obesity according to BMI and WC. Non-obese individuals were recruited as controls.ResultsThe prevalence of CRSwNP was higher in the general (OR, 1.438; 95% CI, 1.170 to 1.768; p<0.001) and central (OR, 1.251; 95% CI, 1.031 to 1.520; p=0.033) obesity groups than in the control group. Prevalence of CRSsNP was not correlated with obesity. In a logistic regression analysis, olfactory dysfunction (OR, 1.329; 95% CI, 1.137 to 1.553; p<0.001) and purulent discharge (OR, 1.383; 95% CI, 1.193 to 1.603; p<0.001) showed a higher incidence in the central obesity group than in the control group.ConclusionsWe demonstrated an association between CRSwNP and general and central obesity. Further investigations on the mechanism underlying this correlation are necessary for an improved understanding of the pathogenesis of CRSwNP.

Objective To describe malpractice payments made on behalf of otolaryngologists, analyze trends over time, and test the association of payment amount with severity of alleged malpractice and patient age. Study Design Retrospective cross-sectional analysis. Setting National Practitioner Data Bank. Subjects and Methods This study comprised all payments made on behalf of otolaryngologists from 1991 to 2018 that were reported to the National Practitioner Data Bank. Descriptive statistics were calculated within and across years. Trends in payments were analyzed with the Mann-Kendall test. Generalized linear regression was utilized to test for association of payment amount with severity of the alleged injury and patient age. Results From 1991 to 2018, there was a significant decrease in the number of payments (272 to 81) and number of otolaryngologists on whose behalf payments were made (250 to 77). Mean and median payments increased significantly from $248,848 to $420,386 and from $96,813 to $275,000, respectively. By severity of alleged injury, mean payments ranged from $39,755 (95% CI, $20,957-$75,412) for insignificant injury to $754,349 (95% CI, $624,847-$910,692) for patients who were left quadriplegic, sustained brain damage, or required lifelong care. By patient age, mean payments for patients ≥60 years old were $191,465 (95% CI, $159,880-$229,292) versus $247,878 (95% CI, $209,416-$293,402) for patients aged 20 to 39 years and $232,225 (95% CI, $197,691-$272,793) for patients aged 40 to 59 years. Conclusion The annual number and total value of malpractice payments decreased, while the annual mean and median payments increased. Payment amount was associated with severity of alleged malpractice and patient age.

Abstract In this study, the resistance of FIB prepared vias was characterized by the Kelvin probe technique and their physical characteristics studied using cross-sectional analysis. Two domains of resistivity were isolated in relation to the ion beam current used for the deposition of the via metal (Pt). Also submicrometer vias were investigated on 4.2 µm deep metal lines of a BiCMOS aluminum based design and a CMOS 090 copper based one. It is shown that the controlling parameter is the shape and volume of the contact, and that the contact formation is favored by the amount of over-mill of the via into the metal line it will contact.
