Abstract

Purpose: We evaluated the contribution to cancer detection of supplemental breast ultrasound screening in women with dense breasts based on a single center experience by comparing our results with similar programs elsewhere. Methods: We performed a retrospective review of handheld sonographer-performed screening ultrasound exams at our academic breast imaging center, from January 1st to December 31st, 2019. Breast density, breast cancer risk factors, BI-RADS assessment, and lesion pathology were reviewed and tallied, followed by derivation of the biopsy rate, breast cancer detection rate, PPV3 and average tumor size. These values were compared to published results of breast screening programs elsewhere. Results: 695 screening breast ultrasounds for women with dense breasts and negative mammograms were performed in 2019. The biopsy rate was 1.3%, breast cancer detection rate was 7 in 1000, PPV3 was 42%, and the average tumor size was 9.0 ± 1.4 mm. Conclusions: The first-year data of the breast screening ultrasound program at our practice are promising, demonstrating comparable cancer detection rate, higher PPV3, and similar biopsy rate in those with dense breasts compared with similar programs elsewhere. Longitudinal analysis and larger sample size are required for validation. Comparison of incidence and prevalence screening data is also warranted to elucidate the true value of this program.

Abstract

Background It is well known that swallowing problems are a common symptom in palliative care patients (Bogaardt et al., 2015). The emotional, physiological and psychological impact of swallowing problems cannot be underestimated on the patient, their families and carers. Aims To reduce the impact of swallowing difficulties by ensuring patients can eat and drink safely, efficiently and nutritiously. To develop and roll out a training programme for healthcare professionals involved in the preparation, formation and delivery of modified diets/fluids. Method A collaborative working party including Speech and Language Therapy(SLT), Dietetics, Catering and Housekeeping was set up to review and improve the modified diets and fluids that are offered to our patients with swallowing difficulties. The review included patient and staff feedback and focused on consistency, appearance, taste and texture. As a multi-disciplinary team, each discipline provided a different knowledge base: SLT focusing on swallowing safety, Dietician focusing on nutritional content, Catering with the preparation and cooking of the food and Housekeeping with food presentation. Results A new puree menu has been developed with standardised texture and consistency with the use of puree moulds to improve appearance. A daily smoothie round is now offered to our inpatients and day hospice. A formal evaluation is in progress. Initial feedback from patients and staff has been positive. ‘It looked like chicken and even tasted like chicken. This is the first puree meal I have actually enjoyed!’ A training programme on modified diets was developed and is being delivered on a rolling basis. Conclusions We believe by evaluating and improving our modified diets and fluids that are offered to patients with swallowing difficulties, these patients can continue to eat and drink safely and nutritiously through the development of an innovative new modified diet menu thus reducing the distress that can be caused by the impact of these difficulties.

Abstract

The National Lung Screening Trial (NLST) is a randomized multicenter study comparing low-dose helical computed tomography (CT) with chest radiography in the screening of older current and former heavy smokers for early detection of lung cancer, which is the leading cause of cancer-related death in the United States. Five-year survival rates approach 70% with surgical resection of stage IA disease; however, more than 75% of individuals have incurable locally advanced or metastatic disease, the latter having a 5-year survival of less than 5%. It is plausible that treatment should be more effective and the likelihood of death decreased if asymptomatic lung cancer is detected through screening early enough in its preclinical phase. For these reasons, there is intense interest and intuitive appeal in lung cancer screening with low-dose CT. The use of survival as the determinant of screening effectiveness is, however, confounded by the well-described biases of lead time, length, and overdiagnosis. Despite previous attempts, no test has been shown to reduce lung cancer mortality, an endpoint that circumvents screening biases and provides a definitive measure of benefit when assessed in a randomized controlled trial that enables comparison of mortality rates between screened individuals and a control group that does not undergo the screening intervention of interest. The NLST is such a trial. The rationale for and design of the NLST are presented.

Abstract

This work reports the use of ultrasound radio frequency (RF) time series analysis as a method for ultrasound-based classification of malignant breast lesions. The RF time series method is versatile and requires only a few seconds of raw ultrasound data with no need for additional instrumentation. Using the RF time series features, and a machine learning framework, we have generated malignancy maps, from the estimated cancer likelihood, for decision support in biopsy recommendation. These maps depict the likelihood of malignancy for regions of size $1~{\hbox {mm}}^{2}$ within the suspicious lesions. We report an area under receiver operating characteristics curve of 0.86 (95% confidence interval [CI]: 0.84%–0.90%) using support vector machines and 0.81 (95% CI: 0.78–0.85) using Random Forests classification algorithms, on 22 subjects with leave-one-subject-out cross-validation. Changing the classification method yielded consistent results which indicates the robustness of this tissue typing method. The findings of this report suggest that ultrasound RF time series, along with the developed machine learning framework, can help in differentiating malignant from benign breast lesions, subsequently reducing the number of unnecessary biopsies after mammography screening.

Abstract

The Mattis Dementia Rating Scale (DRS), a widely used dementia screening instrument, generates five subscale scores in the areas of Attention (ATT), Initiation-Perseveration (IP), Construction (CN), Conceptualization (CON), and Memory (MEM). The present study sought to determine the criterion validity of the DRS subscales in a sample of 50 patients with Alzheimer's disease (25 with mild and 25 with moderate dementia). Subject performance on the five DRS subscales was correlated with performance on five well-validated neuropsychological criterion measures using Pearson r and stepwise regression. On a univariate level, each DRS subscale correlated most strongly with its assigned neuropsychological criterion measure. On a multivariate level, each DRS subscale emerged as the Step 1 predictor of its assigned criterion measure, with the exception of DRS CN, which was the Step 2 predictor. The results suggested that overall the DRS subscales are valid measures of their respective constructs and have value for both clinical and research purposes in mild and moderate dementia.

Abstract

Purpose: To determine the negative predictive value of sonographically guided 14-gauge core needle biopsy of breast masses, with detailed analysis of any false-negative cases. Materials and methods: We reviewed 669 cases of sonographically guided 14-gauge core needle biopsies that had benign pathologic findings. Given a benign pathology on core biopsy, true-negatives had either benign pathology on surgical excision or at least 2 years of stable imaging and/or clinical follow-up; false-negatives had malignant histology on surgical excision. Results: Follow-up was available for 339 breast lesions; 117 were confirmed to be benign via surgical excision, and 220 were stable after 2 years or more of imaging or clinical follow-up (mean follow-up time 33.1 months, range 24–64 months). The negative predictive value was determined to be 99.4%. There were 2 false-negative cases, giving a false-negative rate of 0.1%. There was no delay in diagnosis in either case because the radiologist noted discordance between imaging and core biopsy pathology, and recommended surgical excision despite the benign core biopsy pathology. Conclusions: Sonographically guided 14-gauge core needle biopsy provides a high negative predictive value in assessing breast lesions. Radiologic/pathologic correlation should be performed to avoid delay in the diagnosis of carcinoma.

Abstract

Objectives The objective of this study was to compare breast cancer outcomes among women subject to different policies on mammography screening frequency. Setting Data were obtained for women participating in the Screening Mammography Programme of British Columbia (SMPBC) for 1988–2005. The SMPBC changed its policy for women aged 50–79 years from annual to biennial mammography in 1997, but retained an annual recommendation for women aged 40–49 years. Methods Breast cancer outcomes were compared for women participating in the programme before and after 1997 for two groups: ages 40–49 and 50–79 years. Results There were data on 658,151 women. Comparing pre-1997 and post-1997, the median interscreen interval increased by 11.1 months in women 50–79 but by only 0.3 months in women aged 40–49. Excluding those detected at initial screen, 6291 breast cancers were identified. Comparing pre-1997 and post-1997: the relative rates (RR) of screen detected cancer increased in women aged 40–49 (RR = 1.32) and the rate of invasive cancers ≥20 mm at diagnosis decreased (RR = 0.83); the rate of cancers with axillary node involvement increased in women aged 50–79 (RR = 1.23). Cancer survival improved after 1997 for women diagnosed at ages 40–49 (hazard ratio = 0.62), but was unchanged for women aged 50–79. Breast cancer mortality rates did not change between the periods in either age group. Conclusion The proximal cancer outcomes considered (staging and survival) improved in women aged 40–49 but this was offset in women aged 50–79 associated with the change in screen frequency. These changes did not result in alterations in breast cancer mortality rates in either age group.

Abstract

Mammographic screening is a proven method for the early detection of breast cancer. The authors analyzed the impact of service mammographic screening on breast cancer mortality among British Columbia women who volunteered to be screened by the Screening Mammography Program of British Columbia. A cohort of women having at least one mammographic screen by Screening Mammography Program of British Columbia between the ages of 40 and 79 in the period 1988-2003 was identified. All cases and deaths from breast cancer occurring in British Columbia were identified from the British Columbia Cancer Registry and linked to the screening cohort. Expected deaths from breast cancer in the cohort were calculated using incidence and survival rates for British Columbia women not in the cohort. Adjustment was made for age and socioeconomic status of their area of residence at time of diagnosis. The breast cancer mortality ratio was calculated by dividing observed by expected breast cancer deaths. The mortality ratio (95% confidence interval) was 0.60 (0.55, 0.65) for all ages combined (p < 0.0001). The mortality ratio in women aged 40-49 at first screening was 0.61 (0.52, 0.71), similar to that in women over 50 (p = 0.90). Exclusion of mortality associated with breast cancers diagnosed after age 50 in women starting screening in their 40s increased the mortality ratio to 0.63 (0.52, 0.77), but it remained statistically significant. Correction for self-selection bias using estimates from the literature increased the mortality ratio for all ages to 0.76. Mammographic screening at all ages between 40 and 79 reduced subsequent mortality rates from breast cancer.

Abstract

This study was undertaken to determine the power bases used by middle school and high school principals in the Baltimore city Public schools (BCPS), and how their use of power affects teachers' satisfaction with their work and their principal. The three research questions posed in this study were: 1. To what extent is there a correlation between teacher satisfaction with work and supervisor, and the teacher's perceived classification of his/her principal's use of power? 2. To what extent is there congruence between the principal's self-perception of his/her use of power and the teacher's perception of the principal's use of power? 3. Are there differences in the middle school and high school principals' uses of power based on their teachers' perceived classifications? The subjects for this study were middle school principals, middle school teachers, high school principals, and high school teachers in the BCPS. The middle school and high school principals completed the Power Perception Profile: Perception of Self (PPPS). The middle school and high school teachers completed the Power Perception Profile: Perception of Other (PPPO) and the Cornell Job Description Index (JDI). Of the 41 principals, 24 principals volunteered to participate. The middle school and high school tenured teachers numbered 922. Of the 922 tenured teachers, 387 tenured teachers returned the instrument. The seven power bases measured by the PPPS and the PPPO were (a) coercive power, (b) connection power, (c) information power, (d) expert power, (e) legitimate power, (f) referent power, and (g) reward power. The subtests used to measure the teachers' level of satisfaction were (a) Supervision, and (b) Work on Present Job. Based on the findings of this study, teacher dissatisfaction with principal or with work is associated with the principal's use of coercive power, connection power, and reward power. The principal's use of information power did not appear to affect teacher satisfaction with work o

Abstract

Renal sizes in a group of 68 patients suffering from various nephropathies were compared to expected normal values.Kidneys with lipoid nephrosis and lobular glomerulonephritis were shown to be statistically increased in size, whereas no statistical difference was noted in cases of membranous, membranoproliferative and latent glomerulonephritis. These 2 relatively new entities should be included in the differential diagnosis of enlarged kidneys with no other apparent abnormality on excretory urography.

Abstract

Purpose: We evaluated the contribution to cancer detection of supplemental breast ultrasound screening in women with dense breasts based on a single center experience by comparing our results with similar programs elsewhere., Methods: We performed a retrospective review of handheld sonographer-performed screening ultrasound exams at our academic breast imaging center, from January 1st to December 31st, 2019. Breast density, breast cancer risk factors, BI-RADS assessment, and lesion pathology were reviewed and tallied, followed by derivation of the biopsy rate, breast cancer detection rate, PPV3 and average tumor size. These values were compared to published results of breast screening programs elsewhere., Results: 695 screening breast ultrasounds for women with dense breasts and negative mammograms were performed in 2019. The biopsy rate was 1.3%, breast cancer detection rate was 7 in 1000, PPV3 was 42%, and the average tumor size was 9.0 ± 1.4 mm., Conclusions: The first-year data of the breast screening ultrasound program at our practice are promising, demonstrating comparable cancer detection rate, higher PPV3, and similar biopsy rate in those with dense breasts compared with similar programs elsewhere. Longitudinal analysis and larger sample size are required for validation. Comparison of incidence and prevalence screening data is also warranted to elucidate the true value of this program.
