RESUMO
OBJECTIVE: To assess utilization and perceptions of 2D synthesized mammography (SM) for digital breast tomosynthesis (DBT) among practicing U.S. breast radiologists. METHODS: An IRB-exempt 23-question anonymized survey was developed by the Society of Breast Imaging (SBI) Patient Care and Delivery Committee and emailed to practicing U.S. radiologist SBI members on October 9, 2023. Questions assessed respondents' demographics, current mammographic screening protocol, confidence interpreting SM for mammographic findings, and perceived advantages and disadvantages of SM. RESULTS: Response rate was 13.4% (371/2771). Of 371 respondents, 208 were currently screening with DBT/SM (56.1%), 98 with DBT/SM/digital mammography (DM) (26.4%), 61 with DBT/DM (16.4%), and 4 with DM (1.1%). Most respondents felt confident using DBT/SM to evaluate masses (254/319, 79.6%), asymmetries (247/319, 77.4%), and distortions (265/318, 83.3%); however, confidence was mixed for calcifications (agreement 130/320, 40.6%; disagreement 156/320, 48.8%; neutral 34/320, 10.6%). The most frequently cited disadvantage and advantage of SM were reconstruction algorithm false-positive results (199/347, 57.4%) and lower radiation dose (281/346, 81.2%), respectively. Higher confidence and fewer disadvantages were reported by radiologists who had more SM experience, screened with DBT/SM, or exclusively used Hologic vendor (all P <.05). CONCLUSION: For most survey respondents (56.1%), SM has replaced DM in DBT screening. Radiologists currently screening with DBT/SM or with more SM experience reported greater confidence in SM with fewer perceived disadvantages.
RESUMO
Introduction: Children and young adults with congenital adrenal hyperplasia (CAH) are at increased risk of obesity and insulin resistance. There is evidence that children with CAH have increased visceral adiposity, which has been linked to metabolic syndrome and cardiovascular disease (CVD). The adipokine adiponectin has been shown to correlate with reduced metabolic risk, whereas the adipokines visfatin and leptin have been linked to visceral fat and adipocyte inflammation and can serve as biomarkers of increased metabolic risk. Few studies to date have characterized adipokine levels in children and young adults with congenital adrenal hyperplasia. We sought to investigate the relationship between adiponectin, leptin and visfatin levels to metabolic risk factors and androgen levels in children and young adults with CAH. Methods: Fasting blood was obtained for visfatin, leptin, adiponectin, glucose, insulin, CRP, lipid panel, total cholesterol (TC), triglycerides (TG) and HbA1c, as well as standard laboratory tests to assess adrenal control, from children with CAH due to 21-hydroxylase deficiency. HOMA-IR was calculated based on fasting glucose and insulin. Anthropomorphic measurements of BMI and waist-to-hip ratio were also obtained. Results: Adiponectin and androstenedione were inversely correlated (R = -0.57, p =0.016). There was a positive correlation between leptin and BMI percentile (R = 0.63, p <0.001) as well as leptin and HOMA-IR (R = 0.63, p <0.01). Glucocorticoid dose had a positive correlation with HOMA-IR (R=0.56, p = 0.021). Visfatin was inversely correlated with HDL cholesterol (R = -0.54, p = 0.026) and total cholesterol (R = -0.49, p <0.05). Overweight children and young adults had a significantly higher leptin (p = 0.02) and HOMA-IR (p=0.001) than non-overweight children and young adults. Conclusion: The inverse relationship between adiponectin and androstenedione suggests that better CAH control can reduce the risk of insulin resistance and metabolic syndrome. However, a high glucocorticoid dose appears to increase the risk of insulin resistance, underscoring the delicate balance required when treating CAH.

Importance: A nonadjuvanted bivalent respiratory syncytial virus (RSV) prefusion F (RSVpreF [Pfizer]) protein subunit vaccine was newly approved and recommended for pregnant individuals at 32 0/7 to 36 6/7 weeks' gestation during the 2023 to 2024 RSV season; however, clinical vaccine data are lacking. Objective: To evaluate the association between prenatal RSV vaccination status and perinatal outcomes among patients who delivered during the vaccination season. Design, Setting, and Participants: This retrospective observational cohort study was conducted at 2 New York City hospitals within 1 health care system among patients who gave birth to singleton gestations at 32 weeks' gestation or later from September 22, 2023, to January 31, 2024. Exposure: Prenatal RSV vaccination with the RSVpreF vaccine captured from the health system's electronic health records. Main Outcome and Measures: The primary outcome is preterm birth (PTB), defined as less than 37 weeks' gestation. Secondary outcomes included hypertensive disorders of pregnancy (HDP), stillbirth, small-for-gestational age birth weight, neonatal intensive care unit (NICU) admission, neonatal respiratory distress with NICU admission, neonatal jaundice or hyperbilirubinemia, neonatal hypoglycemia, and neonatal sepsis. Logistic regression models were used to estimate odds ratios (ORs), and multivariable logistic regression models and time-dependent covariate Cox regression models were performed. Results: Of 2973 pregnant individuals (median [IQR] age, 34.9 [32.4-37.7] years), 1026 (34.5%) received prenatal RSVpreF vaccination. Fifteen patients inappropriately received the vaccine at 37 weeks' gestation or later and were included in the nonvaccinated group. During the study period, 60 patients who had evidence of prenatal vaccination (5.9%) experienced PTB vs 131 of those who did not (6.7%). Prenatal vaccination was not associated with an increased risk for PTB after adjusting for potential confounders (adjusted OR, 0.87; 95% CI, 0.62-1.20) and addressing immortal time bias (hazard ratio [HR], 0.93; 95% CI, 0.64-1.34). There were no significant differences in pregnancy and neonatal outcomes based on vaccination status in the logistic regression models, but an increased risk of HDP in the time-dependent model was seen (HR, 1.43; 95% CI, 1.16-1.77). Conclusions and Relevance: In this cohort study of pregnant individuals who delivered at 32 weeks' gestation or later, the RSVpreF vaccine was not associated with an increased risk of PTB and perinatal outcomes. These data support the safety of prenatal RSVpreF vaccination, but further investigation into the risk of HDP is warranted.

PURPOSE: To evaluate the rate of hyperechoic liver lesions that are clinically actionable and evaluate imaging and clinical factors associated with these to determine the need for follow-up. MATERIALS AND METHODS: This retrospective study included 228 hyperechoic hepatic lesions on ultrasound in 228 patients. Reference standards included either dynamic contrast enhanced MRI (n = 130) or CT (n = 46), follow-up ultrasound performed at least 2 years from baseline (n = 50), or histopathology (n = 2). Three radiologists independently assessed imaging features including lesion orientation, degree of hyper-echogenicity, lesion heterogeneity, and background liver echotexture. Univariable and multivariable logistic regression was used to determine features associated with an actionable hyperechoic lesion. RESULTS: Of the 228 hyperechoic lesions, 14 (6.1%) lesions were clinically actionable (or requiring follow-up), and 214 (93.9%) were clinically insignificant. Features that differed between patients with clinically insignificant vs. actionable lesions included: age (52.9 ± 15.1 vs. 63.9 ± 15.8 years, p = 0.004), male sex (43.9% vs 71.4%, p = 0.045), history of cirrhosis (6.5% vs 50%, p < 0.001), lesion size (1.9 ± 1.4 cm vs. 3.5 ± 2.8 cm, p = 0.003), heterogeneous lesion echogenicity (16.4% vs. 50%, p = 0.006), and cirrhotic/coarsened background liver (7.5% vs. 35.7%, p = 0.005). Stepwise logistic regression and multivariable analysis identified age, presence of cirrhosis, and lesion size as features most predictive of an actionable lesion (OR 1.04, 24.3, 1.77 respectively). Reader agreement for imaging features was fair to moderate (k = 0.29-0.53). 100%(168/168) of hyperechoic liver lesions measuring ≤ 3 cm in patients without a history of malignancy or underlying liver disease were clinically insignificant. CONCLUSION: Our study findings support the overall favorable diagnoses of hyperechoic liver lesions ≤ 3 cm in patients without underlying risk factors.
RESUMO
OBJECTIVES: The pediatric gastroenterology workforce has grown in the last few decades. The North American Society of Pediatric Gastroenterology, Hepatology and Nutrition (NASPGHAN) formed a task force to understand current pediatric gastroenterology organizations' practice structures. METHODS: 19-item electronic survey was distributed to NASPGHAN members who were clinical or academic division directors. RESULTS: 30% responded to the survey, all directors of academic practices. The median number of clinical sessions per week was seven sessions, and the median individual work relative value unit (wRVU) target for practices was 4000-4500. Healthcare team ratios compared to provider clinical full-time equivalent were reported as the following: Nursing 0.80, medical assistant (MA) 0.29, dietitian 0.29, social worker 0.14, and psychologist 0.13. Regarding compensation, 68.0% were salaried with bonus based on billing or director decision, 28.0% were salaried with no incentive pay, and 4.0% were salaried with a portion at risk if the target was not met, and a bonus was given if the target was met. Most practices participated in a wellness activity with the most common strategies being didactic lectures about physician burnout (80%), annual burnout check-ins (68%), and/or after-hours social activities (60%). CONCLUSIONS: Pediatric gastroenterology practices vary regarding clinical sessions per week and annual wRVU targets with the median at seven sessions per week and an annual goal of 4000-4500 wRVUs, similar to reported national benchmark goals at the 50th percentile. Healthcare teams, including nursing, MAs, dietitians, social workers, and psychologists, had similar ratios of staff to providers for all sizes and types of practices. Most practices are engaging in wellness initiatives.

PURPOSE: To evaluate the yield of MR-directed ultrasound for MRI detected breast findings. METHODS: This retrospective study included 857 consecutive patients who had a breast MRI between January 2017-December 2020 and received a BI-RADS 4 assessment. Only exams recommended for MR-directed ultrasound were included in the study, yielding 765 patients. Findings were characterized by presence or absence of a sonographic correlate. Utilizing the electronic medical record, for those with a sonographic correlate, the size, location, and morphology were noted. Imaging guided (Ultrasound and MRI) pathology results as well as excisional pathology results were recorded. A multivariable logistical regression analysis was used to investigate the clinical utility of MR-directed ultrasound. RESULTS: There were 1262 MRI-detected BI-RADS category 4 findings in 765 patients. Of the 1262 findings, MR-directed ultrasound was performed on 852 (68 %). Of these, 291/852 (34 %) had an ultrasound correlate, including 143/291 (49 %) benign lesions, 81/291 (28 %) malignant lesions, 16/291 (5 %) with high-risk pathology and 51/291 (18 %) unknown due to lost to follow-up. Of those findings with ultrasound correlates, 173/291 (59 %) represented masses, 69/291 (24 %) were regions of non-mass enhancement, 22/291 (7.6 %) were foci and 27/291 (9.3 %) fell into the category of other which included lymph node, cysts, and scar tissue. Masses were significantly more likely to be identified on MR-directed ultrasound (p < 0.0001) compared to foci. CONCLUSION: The yield of MR-directed ultrasound is significantly higher for masses, than foci and non-mass enhancement, which should be taken into consideration when recommending an MR-directed ultrasound.

Osteopontin (OPN) and Bone Sialoprotein (BSP), abundantly expressed by osteoblasts and osteoclasts, appear to have important, partly overlapping functions in bone. In gene-knockout (KO, -/-) models of either protein and their double (D)KO in the same CD1/129sv genetic background, we analyzed the morphology, matrix characteristics, and biomechanical properties of femur bone in 2 and 4 month old, male and female mice. OPN-/- mice display inconsistent, perhaps localized hypermineralization, while the BSP-/- are hypomineralized throughout ages and sexes, and the low mineralization of young DKO mice recovers with age. The higher contribution of primary bone remnants in OPN-/- shafts suggests a slow turnover, while their lower percentage in BSP-/- indicates rapid remodeling, despite FTIR-based evidence in this genotype of a high maturity of the mineralized matrix. In 3-point bending assays, OPN-/- bones consistently display higher Maximal Load, Work to Max. Load and in young mice Ultimate Stress, an intrinsic characteristic of the matrix. Young male and old female BSP-/- also display high Work to Max. Load along with low Ultimate Stress. Principal Component Analysis confirms the major role of morphological traits in mechanical competence, and evidences a grouping of the WT phenotype with the OPN-/- and of BSP-/- with DKO, driven by both structural and matrix parameters, suggesting that the presence or absence of BSP has the most profound effects on skeletal properties. Single or double gene KO of OPN and BSP thus have multiple distinct effects on skeletal phenotypes, confirming their importance in bone biology and their interplay in its regulation.

BACKGROUND: Patients with a personal or family history of cancer may have elevated risk of developing future cancers, which often remains unrecognized due to lapses in screening. This pilot study assessed the usability and clinical outcomes of a cancer risk stratification tool in a gynecologic oncology clinic. METHODS: New gynecologic oncology patients were prompted to complete a commercially developed personal and family history-based risk stratification tool to assess eligibility for genetic testing using National Comprehensive Cancer Network criteria and estimated lifetime breast cancer risk using the Tyrer-Cuzick model. After use of the risk stratification tool, usability was assessed via completion rate and the System Usability Scale, and health literacy was assessed using the BRIEF Health Literacy Screening Tool. RESULTS: 130 patients were prompted to complete the risk stratification tool; 93 (72%) completed the tool. Race and ethnicity and insurance type were not associated with tool completion. The median System Usability Scale score was 83 out of 100 (interquartile range, 60-95). Health literacy positively correlated with perceived usability. Public insurance and race or ethnicity other than non-Hispanic White was associated with lower perceived usability. Sixty (65%) patients met eligibility criteria for genetic testing, and 21 (38% of 56 eligible patients) were candidates for enhanced breast cancer screening based on an estimated lifetime breast cancer risk of ≥20%. CONCLUSIONS: A majority of patients completed the digital cancer risk stratification tool. Older age, lower health literacy, public insurance, and race or ethnicity other than non-Hispanic White were associated with lower perceived tool usability.

OBJECTIVES: To assess effects of a Simulation-Based Discharge Education Program (SDP) on long-term caregiver-reported satisfaction and to compare clinical outcomes for children with new tracheostomies whose caregivers completed SDP versus controls. METHODS: The study employed a mixed methods approach: (1) a qualitative analysis of feedback from caregivers who previously completed SDP, and (2) a quantitative retrospective case-control study comparing outcomes between children with new tracheostomies whose caregivers completed SDP versus controls, matched on discharge disposition and age. The primary outcome was emergency department visits for tracheostomy-related issues within 1 year of discharge. RESULTS: Feedback from 18 interviews was coded into 5 themes: knowledge acquisition, active learning, comfort and preparedness, home application of skills, and overall assessment. Caregivers of 27 children (median age 26 months [interquartile range (IQR) 5.5 months-11 years]) underwent SDP training. Clinical outcomes of these children were compared with 27 matched children in the non-SDP group (median age 16 months [IQR 3.5 months-10 years]). There was no significant difference in ED visits for tracheostomy-related complications within 1 year of discharge between the SDP group and non-SDP group (2 [IQR 0-2] vs 1 [IQR 0-2], P = .2). CONCLUSIONS: Caregivers reported overwhelmingly positive experiences with SDP that persisted even 4 years after training. Caregiver participation in SDP did not yield a significant difference in ED visits within 1 year of discharge for tracheostomy-related complications compared with control counterparts. Future steps will identify more effective methods for comparing and analyzing clinical outcomes to further validate impacts of simulation-based programs.

BACKGROUND: The efficacy of botulinum toxin for management of myofascial pain disorder (MPD) remains controversial. PURPOSE: The purpose was to determine if the use of onabotulinumtoxinA (onabotA) in patients with MPD reduces pain, improves function, or enhances quality of life (QoL). STUDY DESIGN, SETTING, AND SAMPLE: This is a multicenter, prospective, randomized, double-blinded, placebo-controlled clinical trial. Subjects with orofacial pain were screened for MPD as defined by the Diagnostic Criteria for Temporomandibular Disorders. PREDICTOR VARIABLE: The primary predictor variable was MPD treatment with random assignment to onabotA or placebo (saline). MAIN OUTCOME VARIABLE: The primary outcome variable was pain before treatment (T0) and at 1 month (T1) using a visual analog scale. Secondary outcome variables included pain at 2 months (T2) and 3 months (T3), maximal incisal opening (MIO), jaw function (jaw functional limitation scale), and QoL (Short Form 36) measured at T0, T1, T2, and T3. COVARIATES: Covariates included subject demographics, prior treatments, and temporomandibular joint signs/symptoms. ANALYSES: Descriptive and bivariate statistics included χ2 test, Fisher's exact test, or t-test. RESULTS: Seventy five subjects with a mean age of 37 (±11) and 35 (±12) years in the onabotA and placebo groups, respectively (P = .6). Females represented 32 (86%) and 29 (76%), respectively (P = .3). Mean visual analog scale pain score in the onabotA group was 58 (±15), 39 (±24), 38 (±23), and 38 (±20) at T0, T1, T2, and T3, respectively; and the placebo group was 54 (±14), 40 (±23), 34 (±20), and 36 (±22) at T0, T1, T2, and T3, respectively. There was no statistically significant difference in pain between groups at any time point (P = .36). There was no statistically significant difference between groups in MIO (P = .124), jaw function (P = .236), or QoL domains (P > .05) at any time point. Within-group improvement in pain was seen in both groups (P < .005). Within-group improvement in jaw function was seen in the onabotA (P = .007) and placebo (P = .005) groups. There was no within-group improvement in MIO or QoL with either group (P > .05). CONCLUSIONS: OnabotA and saline (placebo) injections both decrease pain and improve jaw function in subjects with MPD.

PURPOSE: Novel therapies are needed to extend survival in metastatic castration-resistant prostate cancer (mCRPC). Prostate-specific membrane antigen (PSMA), a cell surface antigen overexpressed in PC, provides a validated target. This dose-escalation study investigated the safety, efficacy, maximum tolerated dose (MTD), and recommended phase II dose (RP2D) for 225Ac-J591, anti-PSMA monoclonal antibody J591 radiolabeled with the alpha emitter actinium-225. METHODS: Following investigational new drug-enabling preclinical studies, we enrolled patients with progressive mCRPC that was refractory to or who refused standard treatment options (including androgen receptor pathway inhibitor and had received or been deemed ineligible for taxane chemotherapy). No selection for PSMA was performed. Patients received a single dose of 225Ac-J591 at one of seven dose-escalation levels followed by expansion at the highest dose. Primary end point of dose-escalation cohort was determination of dose-limiting toxicity (DLT) and RP2D. RESULTS: Radiochemistry and animal studies were favorable. Thirty-two patients received 225Ac-J591 in an accelerated dose-escalation design (22 in dose escalation, 10 in expansion). One patient (1 of 22; 4.5%) experienced DLT in cohort 6 (80 KBq/kg) but none in cohort 7; MTD was not reached, and RP2D was the highest dose level (93.3 KBq/kg). The majority of high-grade adverse events (AEs) were hematologic with an apparent relationship with administered radioactivity. Nonhematologic AEs were generally of low grade. Prostate-specific antigen (PSA) declines and circulating tumor cell (CTC) control were observed: 46.9% had at least 50% PSA decline at any time (34.4% confirmed PSA response), and protocol-defined CTC count response occurred in 13 of 22 (59.1%). CONCLUSION: To our knowledge, this is the first-in-human phase I dose-escalation trial of a single dose of 225Ac-J591 in 32 patients with pretreated progressive mCRPC demonstrated safety and preliminary efficacy signals. Further investigation is underway.

RATIONALE AND OBJECTIVE: To determine if patient demographic data, medical history, physical examination, and laboratory tests will help predict likelihood of imaging-based diagnosis using CT of the neck performed in the ED for a chief complaint of throat pain. MATERIAL AND METHODS: Single institutional, retrospective review of 367 CT scans of the neck performed for the evaluation of throat pain in the ED from August 2013 to September 2019. Patients' clinical history, physical exams, lab findings, and imaging results were recorded. RESULTS: A total of 367 CT scans of the neck performed for the evaluation of throat pain included a recorded exam and clinical history. Of these cases, we noted that the presence of cervical lymphadenopathy (OR = 2.69; 95% CI, 1.37-5.49), tonsillar findings (OR = 2.94; 95% CI, 1.4-6.57), increased white blood cell count (OR = 1.08; 95% CI, 1.02-1.15), and temperature (OR = 1.94; 95% CI, 1.1-3.6) were associated with increased likelihood of obtaining a diagnostic CT scan. CONCLUSION: Consideration of tonsillar abnormalities, lymphadenopathy, body temperature, and measured leukocyte count prior to ordering CT scans of the neck for throat pain may increase the diagnostic yield of such exams and decrease CT utilization in the ED.

BACKGROUND: As the number and longevity of childhood cancer survivors increases, assessing treatment-associated late effects remains crucial. We longitudinally examined the incidence of and associated risk factors for Leydig cell dysfunction (LCD) and Leydig cell failure (LCF) in men treated for pediatric cancers at our institution. PROCEDURE: We performed a retrospective longitudinal cohort study of adult male survivors treated for various childhood cancers who are at risk for LCD. The outcomes of interest were serum testosterone and luteinizing hormone (LH) levels during childhood and adulthood. Risk factors assessed included treatment with stem cell transplant, total body irradiation (TBI), and exposure to alkylating agents. RESULTS: Out of 118 eligible subjects, 7.6% had LCF and 14.4% had LCD. Median age at last testosterone level was 20 years. Subjects with sufficient testosterone levels in adulthood (N = 105) remained sufficient for a mean of 11.1 years following completion of cancer treatment. We found significant associations between LCF and treatment with TBI (p < .003) and between LCF in adulthood and testosterone insufficiency in childhood (p < .001). No statistically significant association was found between LCF and cyclophosphamide equivalent dose greater than 20 g/m2 (p = .2). LCF/LCD occurred in a small number of nonirradiated patients treated with the highest doses of alkylators. CONCLUSIONS: Incidence of LCF and LCD are low in male survivors of childhood cancer. Longitudinally, there is an association between childhood testosterone insufficiency and LCF in adulthood. Alkylating agents and stem cell transplant without TBI were not associated with LCF in our study.

PURPOSE: Most individuals with a hereditary cancer syndrome are unaware of their genetic status to underutilization of hereditary cancer risk assessment. Chatbots, or programs that use artificial intelligence to simulate conversation, have emerged as a promising tool in health care and, more recently, as a potential tool for genetic cancer risk assessment and counseling. Here, we evaluated the existing literature on the use of chatbots in genetic cancer risk assessment and counseling. METHODS: A systematic review was conducted using key electronic databases to identify studies which use chatbots for genetic cancer risk assessment and counseling. Eligible studies were further subjected to meta-analysis. RESULTS: Seven studies met inclusion criteria, evaluating five distinct chatbots. Three studies evaluated a chatbot that could perform genetic cancer risk assessment, one study evaluated a chatbot that offered patient counseling, and three studies included both functions. The pooled estimated completion rate for the genetic cancer risk assessment was 36.7% (95% CI, 14.8 to 65.9). Two studies included comprehensive patient characteristics, and none involved a comparison group. Chatbots varied as to the involvement of a health care provider in the process of risk assessment and counseling. CONCLUSION: Chatbots have been used to streamline genetic cancer risk assessment and counseling and hold promise for reducing barriers to genetic services. Data regarding user and nonuser characteristics are lacking, as are data regarding comparative effectiveness to usual care. Future research may consider the impact of chatbots on equitable access to genetic services.

BACKGROUND: Although coronary calcification quantification is an established approach for cardiovascular risk assessment, the value of quantifying carotid calcification is less clear. As a result, we performed a systematic review and meta-analysis to evaluate the association between extracranial carotid artery plaque calcification burden and ipsilateral cerebrovascular ischemic events. METHODS: A comprehensive literature search was performed in the following databases: Ovid MEDLINE(R) 1946 to July 6, 2022; OVID Embase 1974 to July 6, 2022; and The Cochrane Library (Wiley). We performed meta-analyses including studies in which investigators performed a computed tomography assessment of calcification volume, percentage, or other total calcium burden summarizable in a single continuous imaging biomarker and determined the association of these features with the occurrence of ipsilateral stroke or transient ischemic attack. RESULTS: Our overall meta-analysis consisted of 2239 carotid arteries and 9 studies. The presence of calcification in carotid arteries ipsilateral to ischemic stroke or in stroke patients compared with asymptomatic patients did not demonstrate a significant association with ischemic cerebrovascular events (relative risk of 0.75 [95% CI, 0.44-1.28]; P=0.29). When restricted to studies of significant carotid artery stenosis (>50%), the presence of calcification was associated with a reduced risk of ischemic stroke (relative risk of 0.56 [95% CI, 0.38-0.85]; P=0.006). When the analysis was limited to studies of patients with mainly nonstenotic plaques, there was an increased relative risk of ipsilateral ischemic stroke of 1.72 ([95% CI, 1.01-2.91]; P=0.04). Subgroup meta-analyses of total calcium burden and morphological features of calcium showed wide variability in their strength of association with ischemic stroke and demonstrated significant heterogeneity. CONCLUSIONS: The presence of calcification in carotid plaque confers a reduced association with ipsilateral ischemic events, although these results seem to be limited among carotid arteries with higher degrees of stenosis. Adoption of carotid calcification measures in clinical decision-making will require additional studies providing more reproducible and standardized methods of calcium characterization and testing these imaging strategies in prospective studies.

OBJECTIVE: Approximately 20% of ovarian cancers are due to an underlying germline pathogenic variant. While pathogenic variants in several genes have been well-established in the development of hereditary ovarian cancer (e.g. BRCA1/2, RAD51C, RAD51D, BRIP1, mismatch repair genes), the role of partner and localizer of BRCA2 (PALB2) remains uncertain. We sought to utilize meta-analysis to evaluate the association between PALB2 germline pathogenic variants and ovarian cancer. METHODS: We conducted a systematic review and meta-analysis. We searched key electronic databases to identify studies evaluating multigene panel testing in people with ovarian cancer. Eligible trials were subjected to meta-analysis. RESULTS: Fifty-five studies met inclusion criteria, including 48,194 people with ovarian cancer and information available on germline PALB2 pathogenic variant status. Among people with ovarian cancer and available PALB2 sequencing data, 0.4% [95% CI 0.3-0.4] harbored a germline pathogenic variant in the PALB2 gene. The pooled odds ratio (OR) for carrying a PALB2 pathogenic variant among the ovarian cancer population of 20,474 individuals who underwent germline testing was 2.48 [95% CI 1.57-3.90] relative to 123,883 controls. CONCLUSIONS: Our meta-analysis demonstrates that the pooled OR for harboring a PALB2 germline pathogenic variant among people with ovarian cancer compared to the general population is 2.48 [95% CI 1.57-3.90]. Prospective studies evaluating the role of germline PALB2 pathogenic variants in the development of ovarian cancer are warranted.
RESUMO
Objective: Congenital adrenal hyperplasia (CAH) is an inherited condition in which individuals require multiple daily doses of medication and are at risk for life-threatening adrenal crisis. The chronic nature and severity of CAH place children at risk for psychiatric morbidity. The aim was to assess the degree of anxiety and depressive symptoms in children with CAH. Methods: A cross-sectional cohort study of children (7-17 years) with CAH and their caregivers were recruited between May and December 2021. Children with hypothyroidism (HT) and their caregivers served as unaffected controls. Validated mental health questionnaires [Children's Depression Inventory 2 Self Report-Short (CDI-2), Screen for Child Anxiety Related Disorders (SCARED), Patient Health Questionnaire modified for Adolescents (PHQ-A); self and proxy] were completed by participants at one clinic visit. Higher scores indicated greater symptoms of anxiety and depression. Results: A total of 60 children and 56 parents participated. Among the children 34 had CAH (68% female, mean age 11.41±2.5, CAH duration 8.5±4.1) and 26 had HT (73% female, mean age 12.7±2.9 years, HT duration 6.0±4.2 years). There was no increase in anxiety and depression symptoms in children with CAH compared to controls. In sub-analyses, children with CAH and controls reported a greater number of anxiety and depression symptoms than their caregivers on the SCARED and CDI-2, respectively. There was no association between adrenal control and the degree of anxiety or depression symptoms. Conclusion: Children with CAH do not have more symptoms of anxiety or depression compared to controls. Child and caregiver-proxy responses lack agreement, suggesting that children with CAH may continue to benefit from routine mental health evaluation, regardless of voiced caregiver concern.

Objectives: To measure prevalence of complementary and alternative medicine (CAM) use in a diverse gynecologic oncology patient population and evaluate how attitudes and beliefs regarding CAM relate to demographic factors. Methods: A validated Attitudes and Beliefs about Complementary and Alternative Medicine (ABCAM) survey was distributed to patients with gynecologic malignancy. Results were evaluated using Pearson's Chi-squared and Fisher's exact tests for categorical variables and Wilcoxon ranks sum and Kruskal-Wallace tests for non-normally distributed variables. Results: One-hundred thirty patients completed the ABCAM survey. Self-reported race and ethnicity included Asian or Pacific Islander (n = 54; 42%), Hispanic/Latino (n = 23; 18%), White (n = 21; 16%), Black or African American (n = 20; 15%), American Indian/Alaska Native (n = 8; 6.2%) and Other (n = 4; 3.1%). Twenty-four respondents (18%) reported use of CAM. There was a significant difference in expected benefits to CAM between respondents of different races/ethnicities (p < 0.001). Black and Asian respondents reported greater expected benefit to CAM. Hispanic/Latino, American Indian/Alaskan Native, and White respondents reported fewer expected benefits. A significant association was found between perceived barriers to CAM and race/ethnicity (p 0.043), with Asian, Hispanic/Latino and White respondents perceiving more barriers while Black and American Indian/Alaskan Natives reported perceiving fewer barriers to CAM. Respondents with incomes greater than $100,000 reported fewer barriers to CAM. Conclusions: Use of CAM among gynecologic oncology patients is lower than previously thought. Income, race, and ethnicity inform patient engagement with CAM and can be used to better tailor the provision of evidence-based CAM interventions to benefit a greater number of gynecologic cancer patients.
RESUMO
Purpose: To evaluate rates of familial disclosure of hereditary cancer syndrome information. Methods: A systematic review and meta-analysis was conducted in accordance with PRISMA guidelines (PROSPERO no.: CRD42020134276). Key electronic databases were searched to identify studies evaluating hereditary cancer syndrome cascade relative disclosure. Eligible studies were subjected to meta-analysis. Results: Thirty-four studies met inclusion criteria. Among 11,711 included relatives, 70% (95% CI 60 - 78%) were informed of their risk of carrying a cancer-associated pathogenic variant; of 2,875 relatives informed of their risk who were evaluated for uptake of cascade testing, 43% (95% CI 27 - 61%) completed testing. Rates of disclosure were higher among female vs male relatives (79% [95% CI 73% - 84%] vs 67% [95% CI 57% - 75%]) and first-degree vs second-degree relatives (83% [95% CI 77% - 88%] vs 58% [95% CI 45 - 69%]). Conclusion: Nearly one-third of at-risk relatives remain uninformed of their risk of carrying a cancer-associated pathogenic variant. Even among those informed, fewer than half subsequently complete genetic testing, representing a critical missed opportunity for precision cancer prevention. Innovation: Five studies evaluating interventions to improve disclosure rates were generally ineffective. Urgent work is needed to elucidate barriers to relative disclosure by probands to develop targeted interventions that can optimize proband-mediated cascade genetic testing rates.
