RESUMO
PURPOSE: To examine associations between anxiety and depressive symptoms across adolescence and young adulthood with subsequent maternal- and paternal-infant bonding at 1 year postpartum. METHODS: The data were from a prospective, intergenerational cohort study. Participants (381 mothers of 648 infants; 277 fathers of 421 infants) self-reported depression and anxiety at three adolescent waves (ages 13, 15 and 17 years) and three young adult waves (ages 19, 23 and 27 years). Subsequent parent-infant bonds with infants were reported at 1 year postpartum (parent age 29-35 years). Generalised estimating equations (GEE) separately assessed associations for mothers and fathers. RESULTS: Mean postpartum bonding scores were approximately half a standard deviation lower in parents with a history of persistent adolescent and young adult depressive symptoms (maternal ßadj = - 0.45, 95% CI - 0.69, - 0.21; paternal ßadj = - 0.55, 95% CI - 0.90, 0.20) or anxiety (maternal ßadj = - 0.42, 95% CI - 0.66, - 0.18; paternal ßadj = - 0.49, 95% CI - 0.95, 0.03). Associations were still mostly evident, but attenuated after further adjustment for postpartum mental health concurrent with measurement of bonding. CONCLUSIONS: Persistent symptoms of depression or anxiety spanning adolescence and young adulthood predict poorer emotional bonding with infants 1-year postbirth for both mothers and fathers.

OBJECTIVES: To assess the psychometric properties, including face, content, criterion and known-groups validity and reliability, of scales to measure oral health-related self-efficacy and fatalism in a regional Aboriginal adult population in Australia. METHODS: Four hundred Aboriginal adults (aged 18-82 years, 67% female) completed a self-report questionnaire including items pertaining to oral health-related self-efficacy and fatalism. Structural validity was determined in exploratory factor analysis (EFA) with principal components analysis for each scale. Criterion validity was assessed between the instruments and theoretically related variables. Known-groups validity was investigated by comparing the scores in different population groups according to age, sex, education and employment. Reliability of the scales was assessed through internal consistency. RESULTS: The EFA confirmed a single factor structure for self-efficacy and fatalism scales, with Cronbach's alphas of 0.93 and 0.89 respectively. The two scales were not correlated. Oral health-related self-efficacy was associated with toothbrush ownership and brushing the previous day supporting criterion validity. Oral health-related fatalism was associated with previous extractions and perceived need for extractions also supporting criterion validity. Both measures were associated with social impact of oral health as measured by the OHIP-14, supporting their criterion validity. Mixed findings were observed in terms of known-groups validity. CONCLUSIONS: There was initial evidence that measures of oral health-related self-efficacy and fatalism displayed adequate psychometric properties in this Aboriginal community. These constructs could have implications for approaches for improving oral health among Aboriginal people.

INTRODUCTION: In extending work on early life antecedents of parenting, we investigate associations between childhood family history of disadvantage, adolescent socioemotional wellbeing, and age at first parenthood and subsequent parenting behaviour. METHODS: Parent-child interactions were recorded when participants in the longitudinal Dunedin Multidisciplinary Health and Development Study (New Zealand) had a three-year-old child. Data were available for 358 mothers and 321 fathers, aged between 17.7 and 41.5 at the time of their child's birth. Associations between parenting and antecedent data on socioeconomic disadvantage, adolescent wellbeing and mental health, as well as current adult mental health and age at parenting, were tested for using structural equation modelling. RESULTS: Family disadvantage in childhood and lower adolescent wellbeing was associated with less positive future parenting, but only adult (not adolescent) anxiety/depression symptoms were directly associated with parenting behaviour. Childhood family disadvantage was associated with further disadvantage across the life course that included less positive parenting of the next generation. In contrast, socioemotional wellbeing during adolescence and later age of onset of parenting were associated with more positive parenting. CONCLUSIONS: Reducing childhood disadvantage and improving socioemotional wellbeing during childhood and adolescence is likely to have intergenerational benefits through better parenting of the next generation.

AIMS: This study aimed to identify risk indicators associated with periodontitis and the contribution of each of the indicators towards the prevalence, extent and severity of periodontitis in a rural Indian population. METHODS: A cross-sectional study design was used to collect data according to National Survey of Adult Oral Health Australia guidelines. A multistage stratified random sampling was followed to select 1401 participants, who were in the age group of 35-54 years. The participants were selected from 50 villages belonging to the 5 sub-provinces of 2 Indian districts. Data were collected through face-to-face interviews and oral examination. Statistical analysis was performed using SAS version 9.3. The univariate, bivariate and multivariate analyses were performed to determine the risk indicators of prevalence, extent and severity of periodontitis. Population attributable fraction was estimated for each of the significant risk indicators of prevalence and extent. RESULTS: In this study, factors such as age, education, tobacco chewing and plaque accumulation were significantly associated with the prevalence of periodontitis. Age, socioeconomic status, method of tooth cleaning, alcohol consumption and plaque accumulation were significant risk indicators for generalized periodontitis. Age, tobacco chewing and plaque were associated with severity of periodontitis in the population. CONCLUSION: The rural population had a high prevalence of periodontitis. Sociodemographic factors, poor oral hygiene, tobacco and alcohol were the main risk indicators attributable to periodontitis.

BACKGROUND: High-dose chemotherapy (HDC) with hematopoietic progenitor cell transplantation is a standard option for relapsed/refractory testicular germ-cell tumor (GCT), but only few data have been reported in female patients with GCT. We conducted a retrospective analysis of female patients with GCT treated with HDC and registered with the European Society for Blood and Marrow Transplantation. PATIENTS AND METHODS: Between 1985 and 2013, 60 registered female patients with GCT, median age 27 years (range 15-48), were treated with salvage HDC. Forty patients (67%) had primary ovarian GCT, 8 (13%) mediastinal, 7 (12%) retroperitoneal and 5 (8%) other primary sites/unknown. Twenty-two patients (37%) received HDC as second-line therapy, 29 (48%) as third-line, and 9 (15%) as fourth- to sixth-line. Nine of 60 patients (15%) received HDC as late-intensification with no evidence of metastasis before HDC. The conditioning HDC regimens comprised carboplatin in 51 of 60 cases (85%), and consisted of a single HDC cycle in 31 cases (52%), a multi-cycle HDC regimen in 29 (48%). RESULTS: Nine cases who underwent late intensification HDC were not evaluable for response. Of the other 51 assessable patients, 17 (33%) achieved a complete response (CR), 8 (16%) a marker-negative partial remission (PRm-), 5 (10%) a marker-positive partial remission, 5 (10%) stable disease, and 13 (25%) progressive disease. There were 3 toxic deaths (6%). With an overall median follow-up of 14 months (range 1-219), 7 of 9 (78%) patients with late intensification and 18 of the 25 patients (72%) achieving a CR/PRm- following HDC were free of relapse/progression. In total, 25 of 60 patients (42%) were progression-free following HDC at a median follow-up of 87 months (range 3-219 months). CONCLUSIONS: Salvage HDC based on carboplatin represents a therapeutic option for female patients with relapsed/refractory GCT.

BACKGROUND: Special Olympics (SO) is commonly cited to play an important role in the lives of individuals with intellectual disabilities (ID). The purpose of the current review was to (a) synthesise key findings regarding the physical, psychological/emotional, social and/or intellectual/cognitive correlates of SO participation for individuals with ID and (b) highlight limitations in the extant research as well as directions for future research. METHOD: A systematic review of electronic databases was undertaken. A total of 46 articles were confirmed to meet study criteria. Quality assessments of included studies were conducted using checklists from the Scottish Intercollegiate Guidelines Network methodology checklists (SIGN 50; SIGN 2008). RESULTS: There was a larger amount of support for physical, psychological/emotional and social outcomes as compared with cognitive/intellectual outcomes; however, many studies were confounded by measurement difficulties, sampling procedures and a lack of replicable methods, which hinder generalisation of results. CONCLUSIONS: This review highlights the need for a continued critical focus on SO programme evaluation research with more rigorous and replicable methods.

AIM: To identify which features of fibroadenomas are associated with false-positive findings at shear wave elastography (SWE). MATERIALS AND METHODS: A total of 151 patients with histologically confirmed fibroadenomata were identified from a prospective database, from a single breast unit. The following features were assessed by two observers who were unaware of the SWE findings: patient age, grey-scale ultrasound lesion diameter (<15 or ≥15 mm), distance from the lesion to skin, composition of surrounding tissue (fatty, mixed or dense), and source of referral (screening or symptomatic). Statistical analysis was carried out using the chi-square test. RESULTS: A statistically significant positive association was found between grey-scale ultrasound lesion size and lesion stiffness. Twenty-nine of 70 (41%) lesions ≥15 mm were stiff, versus 10 of 81 (12%) <15 mm (p=0.001). Patient age, distance from the lesion to skin, make-up of surrounding tissue, and source were not significantly associated with stiffness. CONCLUSION: Fibroadenomas giving false-positive SWE results tend to be larger in size than those that do not. More compression of adjacent normal tissue is assumed to be the cause of the present findings. As previous studies have shown that large cancers tend to be stiffer than smaller cancers, it may be appropriate to vary the quantitative cut-off value used for benign/malignant differentiation in SWE according to lesion size.

AIM: To evaluate the influence of the region of interest (ROI) size and lesion diameter on the diagnostic performance of 2D shear wave elastography (SWE) of solid breast lesions. MATERIALS AND METHODS: A study group of 206 consecutive patients (age range 21-92 years) with 210 solid breast lesions (70 benign, 140 malignant) who underwent core biopsy or surgical excision was evaluated. Lesions were divided into small (diameter <15 mm, n=112) and large lesions (diameter ≥15 mm, n=98). An ROI with a diameter of 1, 2, and 3 mm was positioned over the stiffest part of the lesion. The maximum elasticity (Emax), mean elasticity (Emean) and standard deviation (SD) for each ROI size were compared to the pathological outcome. Statistical analysis was undertaken using the chi-square test and receiver operating characteristic (ROC) analysis. RESULTS: The ROI size used has a significant impact on the performance of Emean and SD but not on Emax. Youden's indices show a correlation with the ROI size and lesion size: generally, the benign/malignant threshold is lower with increasing ROI size but higher with increasing lesion size. CONCLUSIONS: No single SWE parameter has superior performance. Lesion size and ROI size influence diagnostic performance.

AIM: To investigate the contribution of shear-wave elastography (SWE) in diagnosing invasive lobular breast cancer (ILC) in symptomatic patients. MATERIALS AND METHODS: A retrospective case-controlled study of 52 patients with ILC and 52 patients with invasive ductal cancer (IDC), matched for age and tumour size, was performed. Breast density and mammographic and greyscale ultrasound features were graded using Breast Imaging-Reporting and Data System (BI-RADS) classification by two radiologists, blinded to SWE and pathology findings. Forty-four benign lesions were also included. The sensitivity of SWE was assessed, using a cut-off value of 50 kPa for mean elasticity. Statistical significance was evaluated using Chi-square and Chi-square for trend tests. RESULTS: Mean age for both ILC and IDC groups was 67 years. Mean size for ILC was 44 mm and IDC was 37 mm. The sensitivity for detection of ILC and IDC for mammography, greyscale ultrasound, and SWE were 79% versus 87%, 87% versus 98%, 94% versus 100%, respectively. SWE had significantly higher sensitivities than mammography for the detection of both ILC and IDC (p = 0.012 and p = 0.001, respectively). SWE was not significantly more sensitive than greyscale ultrasound for the detection of either tumour type. Four (8%) lobular cancers were benign/normal at both mammography and greyscale ultrasound, but suspicious on SWE. The incremental gain in sensitivity by using SWE in ILC was statistically significant compared to IDC (p = 0.01). CONCLUSION: SWE can diagnose lobular cancers that have benign/normal findings on conventional imaging as suspicious.

BACKGROUND: This study aims to use 30-day readmission rates to investigate the presumption that men and women with learning disabilities (LDs, known internationally as intellectual disabilities) receive poorer quality hospital care than their non-disabled peers. METHOD: A 12-month retrospective audit was conducted using Hospital Episode Statistics (HES) at a single acute hospital in the East of England. This identified all in-patient admissions; admissions where the person concerned was recognised as having a LD; and all emergency readmissions within 30 days of discharge. Additionally, the healthcare records of all patients identified as having a LD and readmitted within 30 days as a medical emergency were examined in order to determine whether or not these readmissions were potentially preventable. RESULTS: Over the study period, a total of 66 870 adults were admitted as in-patients, among whom 7408 were readmitted as medical emergencies within 30 days of discharge: a readmission rate of 11%. Of these 66 870 patients, 256 were identified as having a LD, with 32 of them experiencing at least one emergency readmission within 30 days: a readmission rate of 13%. When examined, the healthcare records pertaining to these 32 patients who had a total of 39 unique 30-day readmissions revealed that 69% (n = 26) of these readmissions were potentially preventable. CONCLUSION: Although overall readmission rates were similar for patients with LDs and those from the general population, patients with LDs had a much higher rate of potentially preventable readmissions when compared to a general population estimate from van Walraven et al. This suggests that there is still work to be done to ensure that this patient population receives hospital care that is both safe and of high quality.

BACKGROUND: To assess the prevalence of clustering of risk indicators for periodontal disease and association of clustering of the risk indicators with sociodemographic factors and the prevalence of moderate/severe periodontal disease in rural Indian 35-54 year-olds. BASIC RESEARCH DESIGN: A multi-stage cluster random sampling design was used for this population-based cross-sectional study. METHOD: Data were collected through in-person interviews relating to sociodemographic factors and habits. Plaque index and periodontal findings were recorded from oral examination. Clustering of risk indicators such as smoking, tobacco chewing, alcohol and plaque were assessed for association with periodontal disease and various other sociodemographic indicators using logistic regression models. Results: Of 1,401 people approached, 873 completed data; a response rate of 62.3%. Clustering of two or more risk indicators was present in 31% of the population. Prevalence of moderate-severe periodontal disease was 46.6%. Simultaneous presence of two/more risk indicators was strongly associated with sociodemographic factors and periodontal disease. CONCLUSIONS: Clustering of two or more of the factors plaque, smoking, chewing tobacco and alcohol, was strongly associated with periodontitis.

BACKGROUND: The aim of this study was to investigate the impact of the high-dose regimen on the outcome of patients with follicular lymphoma (FL) having had autologous stem-cell transplantation (ASCT) in a recent time period. PATIENTS: Between 1995 and 2007, 2233 patients with FL had their first ASCT with either a total body irradiation (TBI)-containing regimen or carmustin, etoposide, cytarabine and melphalan (BEAM), of which 47% were autografted in first remission. RESULTS: After a median observation time of 73 months (interquartile range 30-107), 5- and 10-year non-relapse mortality (NRM) was similar (6% and 10% in both groups). No significant NRM differences became evident after multivariate adjustment for confounders. Secondary malignancies were observed in 9.7% and 7.9% of the patients after TBI and BEAM (P = 0.19), which were treatment-related myelodysplastic syndromes/acute myelogenous leukaemia (t-MDS/AML) in 3.4% and 2.8% (P = 0.57). The median time to t-MDS/AML was around 50 months in both groups. Because of a lower relapse incidence, TBI was associated with better event-free survival reaching statistical significance in the patients transplanted in first remission but not in those transplanted beyond first remission. CONCLUSIONS: In patients with FL who received TBI-based ASCT after 1995 increased NRM and t-MDS/AML risks did not emerge compared with BEAM while disease control was at least equivalent.

OBJECTIVES: Shear wave elastography (SWE) is a promising adjunct to greyscale ultrasound in differentiating benign from malignant breast masses. The purpose of this study was to characterise breast cancers which are not stiff on quantitative SWE, to elucidate potential sources of error in clinical application of SWE to evaluation of breast masses. METHODS: Three hundred and two consecutive patients examined by SWE who underwent immediate surgery for breast cancer were included. Characteristics of 280 lesions with suspicious SWE values (mean stiffness >50 kPa) were compared with 22 lesions with benign SWE values (<50 kPa). Statistical significance of the differences was assessed using non-parametric goodness-of-fit tests. RESULTS: Pure ductal carcinoma in situ (DCIS) masses were more often soft on SWE than masses representing invasive breast cancer. Invasive cancers that were soft were more frequently: histological grade 1, tubular subtype, ≤10 mm invasive size and detected at screening mammography. No significant differences were found with respect to the presence of invasive lobular cancer, vascular invasion, hormone and HER-2 receptor status. Lymph node positivity was less common in soft cancers. CONCLUSION: Malignant breast masses classified as benign by quantitative SWE tend to have better prognostic features than those correctly classified as malignant. KEY POINTS: ⢠Over 90 % of cancers assessable with ultrasound have a mean stiffness >50 kPa. ⢠'Soft' invasive cancers are frequently small (≤10 mm), low grade and screen-detected. ⢠Pure DCIS masses are more often soft than invasive cancers (>40 %). ⢠Large symptomatic masses are better evaluated with SWE than small clinically occult lesions. ⢠When assessing small lesions, 'softness' should not raise the threshold for biopsy.

OBJECTIVES: Despite burgeoning evidence regarding the pathways by which experiences of racism influence health outcomes, little attention has been paid to the relationship between racism and oral health-related behaviours in particular. We hypothesised that self-reported racism was associated with tooth brushing, and that this association was mediated by perceived stress and sense of control and moderated by social support. METHODS: Data from 365 pregnant Aboriginal Australian women were used to evaluate tooth brushing behaviour, sociodemographic factors, psychosocial factors, general health, risk behaviours and racism exposure. Bivariate associations were explored and hierarchical logistic regression models estimated odds ratios (OR) and 95% confidence intervals (CI) for tooth brushing. Perceived stress and sense of control were examined as mediators of the association between self-reported racism and tooth brushing using binary mediation with bootstrapping. RESULTS: High levels of self-reported racism persisted as a risk indicator for tooth brushing (OR 0.51, 95%CI 0.27,0.98) after controlling for significant covariates. Perceived stress mediated the relationship between self-reported racism and tooth brushing: the direct effect of racism on tooth brushing was attenuated, and the indirect effect on tooth brushing was significant (beta coefficient -0.09; bias-corrected 95%CI -0.166,-0.028; 48.1% of effect mediated). Sense of control was insignificant as a mediator of the relationship between racism and tooth brushing. CONCLUSIONS: High levels of self-reported racism were associated with non-optimal tooth brushing behaviours, and perceived stress mediated this association among this sample of pregnant Aboriginal women.. Limitations and implications are discussed.

INTRODUCTION: Evidence-based practice (EBP) is essential for ensuring the delivery of effective and efficient healthcare. Despite this, EBP is not always well implemented in the clinical environment. Evidence suggests that the application of EBP is likely impacted by healthcare workers' attitudes, knowledge and skills. While there has been a recent proliferation of international research examining diagnostic radiographers' attitudes towards, knowledge of and skills in EBP, no such research exists in an Australian context. METHODS: This study presents the results of a validated self-report survey, the evidence-based practice questionnaire (EBPQ), administered to Australian diagnostic radiographers. The data were described and aggregated means were calculated for each of the domains. Inferential statistical tests were computed, including Cronbach's alpha, Pearson's correlations and independent t-tests, and Kruskal-Wallis tests. RESULTS: The aggregated mean for the practice domain was 5.02 (SD 1.104), for the attitudes domain it was 5.41 (SD 1.169), and for the knowledge and skills domain, it was 5.20 (SD 1.177) on a seven-point scale. Significant associations were identified among these domains, with individuals holding higher qualifications and occupying leadership positions more likely to score higher. Additionally, the modality in which an individual primarily practiced appeared to also have an impact on their score. However, no significant correlation was found between any domain and the number of years an individual had been practicing. CONCLUSION: This research has established a baseline of Australian diagnostic radiographers' practices, knowledge skills and attitudes towards evidence-based practice. IMPLICATIONS FOR PRACTICE: This baseline can inform the development of interventions aimed at enhancing the role of evidence-based practice in the sampled population.

BACKGROUND: Response of invasive breast cancer to neoadjuvant chemotherapy (NAC) is variable, and prediction of response is imperfect. We aimed to ascertain whether tissue stiffness in breast cancers, as assessed by shear-wave elastography (SWE) before treatment, is associated with response. METHODS: We retrospectively compared pre-treatment tumour mean tissue stiffness, with post-treatment Residual Cancer Burden (RCB) scores and its components in 40 women with breast cancer treated by NAC using Pearson's correlation coefficient (CC), a general linear model and multiple linear regression. Subgroup analysis was carried out for luminal, HER2-positive and basal immuno-histochemical subtypes. RESULTS: Statistically significant correlations were shown between stiffness and RCB scores and between stiffness and percentage tumour cellularity. The correlation between stiffness and percentage cellularity was strongest (CC 0.35 (P<0.0001) compared with CC 0.23 (P=0.004) for the RCB score). The results of a general linear model show that cellularity and RCB score maintain independent relationships with stiffness. By multiple linear regression, only cellularity maintained a significant relationship with stiffness. CONCLUSION: Pre-treatment tumour stiffness measured by SWE, has a statistically significant relationship with pathological response of invasive breast cancer to NAC.

BACKGROUND: Implantable cardioverter defibrillators (ICD) have been demonstrated to reduce mortality in survivors of life-threatening arrhythmias (secondary prevention) and in patients at increased risk of sudden cardiac death (primary prevention). Other nations have reported significant increases in ICD use in recent years. AIM: To investigate Australian nationwide trends of ICD procedures over a 10-year period (2000-2009). METHODS: A retrospective analysis of the Australian Institute of Health and Welfare's National Hospital Morbidity Database was performed to determine the annual number of ICD implantation and replacement procedures between 2000 and 2009. Rates were calculated using Australian Bureau of Statistics data on the annual estimated population. Time trends in the yearly procedure number and rate were analysed using negative binomial regression models with comparisons made by age and sex. RESULTS: The number of new ICD implantations increased from 708 to 3198 procedures between 2000 and 2009. Replacement procedures increased from 290 to 1378. The implantation rate (per million) increased from 37.0 to 145.6 and the replacement rate from 15.1 to 62.7. When rates were adjusted for age and sex, the implantation rate increased annually by 15.8% and the replacement rate by 16.6% (P < 0.0001). Procedures occurred most commonly in men (implantations: 80.1%; replacements: 78.0%) between ages 70-79. CONCLUSIONS: ICD procedures increased significantly in Australia between 2000-2009. Despite these increases, other studies have suggested ICD devices are currently under-utilised. During the study period, males accounted for the majority of ICD procedures. While there are numerous reasons for this, it is not known if device under-use is more common in females.

OBJECTIVE: Evidence suggests that taller individuals have better health than their shorter counterparts. This study aimed to test the hypothesis that shorter participants in wave-3 of the Aboriginal Birth Cohort (ABC) study, a prospective longitudinal investigation of Indigenous Australian individuals born 1987-1990 at an Australian regional hospital, would have more caries and periodontal disease experience than their taller counterparts. METHODS: Data were collected through oral clinical examinations, anthropometric measures and self-report questionnaires. The outcome variables were participants' caries (mean DMFT) and periodontal disease experience (moderate or severe periodontal disease as defined by the Centre for Disease Control), with height as an explanatory variable. Antecedent anthropometric, socio-demographic, sugar consumption frequency, dental behaviour and substance use variables were used as possible confounders. Linear regression was used in the analysis of caries experience, while adjusted prevalence ratios were used for prevalence of moderate or severe periodontal disease. RESULTS: Higher DMFT was found among participants in the shortest tertile (B=1.02, 95% CI=0.02-2.02) and those who consumed sweets every day or a few days a week (B=1.08, 95% CI=0.11-2.05), while lower DMFT was found among those owning a toothbrush (B=0.80, 95% CI=-0.22-1.82). Periodontal disease was positively associated with the shortest tertile (adjusted PR=1.39, 95% CI=0.96-1.82) and negatively associated with toothbrush ownership (adjusted PR=0.50, 95% CI=0.34-0.66). CONCLUSION: The hypothesis that shorter participants in wave-3 of the ABC study would have higher levels of caries and periodontal disease was confirmed.

BACKGROUND: The aim of this study was to assess the performance of shear wave elastography combined with BI-RADS classification of greyscale ultrasound images for benign/malignant differentiation in a large group of patients. METHODS: One hundred and seventy-five consecutive patients with solid breast masses on routine ultrasonography undergoing percutaneous biopsy had the greyscale findings classified according to the American College of Radiology BI-RADS. The mean elasticity values from four shear wave images were obtained. RESULTS: For mean elasticity vs greyscale BI-RADS, the performance results against histology were sensitivity: 95% vs 95%, specificity: 77% vs 69%, Positive Predictive Value (PPV): 88% vs 84%, Negative Predictive Value (NPV): 90% vs 91%, and accuracy: 89% vs 86% (all P>0.05). The results for the combination (positive result from either modality counted as malignant) were sensitivity 100%, specificity 61%, PPV 82%, NPV 100%, and accuracy 86%. The combination of BI-RADS greyscale and shear wave elastography yielded superior sensitivity to BI-RADS alone (P=0.03) or shear wave alone (P=0.03). The NPV was superior in combination compared with either alone (BI-RADS P=0.01 and shear wave P=0.02). CONCLUSION: Together, BI-RADS assessment of greyscale ultrasound images and shear wave ultrasound elastography are extremely sensitive for detection of malignancy.
