Weight management and physical activity throughout the cancer care continuum.

Mounting evidence suggests that weight management and physical activity (PA) improve overall health and well being, and reduce the risk of morbidity and mortality among cancer survivors. Although many opportunities exist to include weight management and PA in routine cancer care, several barriers remain. This review summarizes key topics addressed in a recent National Academies of Science, Engineering, and Medicine workshop entitled, "Incorporating Weight Management and Physical Activity Throughout the Cancer Care Continuum." Discussions related to body weight and PA among cancer survivors included: 1) current knowledge and gaps related to health outcomes; 2) effective intervention approaches; 3) addressing the needs of diverse populations of cancer survivors; 4) opportunities and challenges of workforce, care coordination, and technologies for program implementation; 5) models of care; and 6) program coverage. While more discoveries are still needed for the provision of optimal weight-management and PA programs for cancer survivors, obesity and inactivity currently jeopardize their overall health and quality of life. Actionable future directions are presented for research; practice and policy changes required to assure the availability of effective, affordable, and feasible weight management; and PA services for all cancer survivors as a part of their routine cancer care.

Axillary lymph node recurrence following wire-directed sentinel lymph node dissection for breast cancer patients with biopsy-proven axillary metastases prior to neoadjuvant chemotherapy at a safety net medical center.

BACKGROUND: Although sentinel lymph node dissection (SLND) after neoadjuvant chemotherapy (NAC) is feasible, axillary management for patients with pretreatment biopsy-proven axillary metastases and who are clinically node-negative after NAC (ycN0) remains unclear. This retrospective study was performed to determine the rate of axillary lymph node recurrence for such patients who had wire-directed (WD) SLND. METHODS: Patients treated with NAC from 2015 to 2020 had axillary nodes evaluated by pretreatment ultrasound. Core biopsies were done on abnormal nodes, and microclips were placed in nodes during biopsy. For patients with biopsy-proven node metastases who received NAC and were ycN0 by clinical exam, WD SLND was done. Patients with negative nodes on frozen section had WD SLND alone; those with positive nodes had WD SLND plus axillary lymph node dissection (ALND). RESULTS: Of 179 patients receiving NAC, 62 were biopsy-proven node-positive pre-NAC and ycN0 post-NAC. Thirty-five (56%) patients were node-negative on frozen section and had WD SLND alone. Twenty-seven (43%) patients had WD SLND + ALND. Forty-seven patients had postoperative regional node irradiation. With median follow-up of 40 months, there were recurrences in 4 (11%) of 35 patients having WD SLND and 5 (19%) of 27 having WD SLND + ALND, but there was only one axillary lymph node recurrence, identified by CT scan. CONCLUSIONS: Axillary node recurrence was very uncommon after WD SLND for patients who had pretreatment biopsy-proven node metastases and were ypN0 after NAC. These patients would be unlikely to derive clinical benefit from the addition of completion ALND to SLND.

Radial Scars and Complex Sclerosing Lesions of the Breast: Prevalence of Malignancy and Natural History Under Active Surveillance.

BACKGROUND: When needle core biopsies (NCBs) of the breast reveal radial scar or complex sclerosing lesions (RSLs), excision is often recommended despite a low risk of malignancy in the modern era. The optimal management of NCBs revealing RSLs is controversial, and understanding of the natural history of unresected RSLs is limited. METHODS: We retrospectively analyzed pathology and imaging data from 148 patients with NCB revealing RSL without atypia from 2015 to 2019 to determine the prevalence of malignancy and the behavior of RSLs undergoing active surveillance (AS). RESULTS: The mean age of patients was 52 years, and most lesions were screen-detected (91%). The median lesion size was 6.0 mm (range 2-39). Most patients (66%, n = 98) underwent immediate surgery, while 34% (n = 50) of patients underwent AS, with a median follow-up of 16 months (range 6-51). Of the excised RSLs, 99% (n = 97) were benign and 1% (n = 1) revealed ductal carcinoma in situ (DCIS). In 17% (n = 17) of cases, additional high-risk lesions were discovered upon excision. Among the 50 patients undergoing AS, no lesions progressed on interval imaging. CONCLUSIONS: In this cohort, 99% of RSLs undergoing excision were benign, 1% revealed DCIS, and there were no invasive cancers. In the first study of patients with RSLs undergoing AS, we found that all lesions either remained stable or resolved. We propose that the vast majority of patients with RSL on NCB can be safely offered AS, and that routine excision is a low-value intervention.

Avoidance of general anesthesia for circumcision in infants under 6 months of age using a modified Plastibell technique.

PURPOSE: There is currently no gold standard for the type of analgesia or preferred circumcision technique in infants requiring circumcision after 1 month of age. Our study presents a modified Plastibell circumcision technique, which offers excellent surgical outcomes, and can be performed under local anesthesia until 6 months of age, thereby avoiding the risks of general anesthesia in delayed circumcision. METHODS: This is a retrospective case series of 508 consecutive male infants between 1 and 6 months of age, from one institution, who all underwent circumcision under local anesthesia, performed by the same pediatric surgeon, from 2013 to 2018. The study parameters included postoperative complications such as re-operation for control of hemorrhage, wound infection, circumcision revision, and urethral meatotomy. RESULTS: There were no re-operations for control of hemorrhage, no wound infections, and no circumcision revisions. One patient developed urethral meatal stenosis requiring urethral meatotomy. CONCLUSION: Our modified Plastibell circumcision technique under local anesthesia is a safe and reproducible alternative for infants between 1 and 6 months of age, whose parents desire circumcision and wish to avoid general anesthesia.

Appropriate Use of Prophylactic Antibiotic Agents in Gynecologic Surgeries at a Midwestern Teaching Hospital.

BACKGROUND: The purpose of this study was to establish compliance with guidelines published by the American College of Obstetricians and Gynecologists (ACOG) regarding prophylactic antibiotic use in gynecologic surgery at our institution, and define areas of improvement to promote antibiotic stewardship. PATIENTS AND METHODS: This was a retrospective cohort study at a single, large tertiary care and teaching hospital in Kansas. Patients who underwent inpatient or outpatient gynecologic surgery during 2013 were included. Based on published guidelines for prophylactic antibiotic agents for gynecologic surgery by ACOG, procedures were classified as antibiotic-indicated or antibiotic-not-indicated. Chi-square and Fisher exact test analysis were used to identify factors associated with antibiotic use. RESULTS: Of the 1,735 cases eligible for inclusion, 1,045 (60.2%) had antibiotic agents recommended per guidelines, and appropriate antibiotic agents were given in 1,031 (98.7%) of those cases. In 690 (39.8%) cases, prophylactic antibiotics were either not recommended or the guidelines are not well defined. Of the 690 cases without indication for antibiotic agents, 394 (57.1%) received prophylactic antibiotic agents. Agreement with guidelines varied substantially based on patient age, race, insurance status, area of residence, and if the procedure was a resident case (p < 0.05). Myomectomy, laparoscopy, and ectopic pregnancy procedures received antibiotic agents against recommendations 96.3%, 75.6%, and 45.5% of the time, respectively. CONCLUSIONS: Peri-operative antibiotics are often administered inappropriately to women undergoing gynecologic surgeries for which published guidelines are not well defined. Future studies need to identify strategies to reduce antibiotic use in surgical procedures unlikely to benefit from prophylaxis.

Treatment and persistence with oral anticoagulants among newly diagnosed patients with non-valvular atrial fibrillation: a retrospective observational study in a US commercially insured and Medicare Advantage population.

OBJECTIVES: With the approval of new non-vitamin K antagonist oral anticoagulants for stroke prevention in non-valvular atrial fibrillation (NVAF), it is anticipated that their introduction may change NVAF treatment patterns; however, there is limited supporting real-world evidence. This study investigated guideline-recommended oral anticoagulation (OAC) treatment and persistence in newly diagnosed patients with NVAF to understand demographic and clinical characteristics. DESIGN: Retrospective observational administrative claims study in the USA. SETTING: Patients with NVAF with ≥1 pharmacy claim for OAC (warfarin, dabigatran, rivaroxaban or apixaban) and no atrial fibrillation diagnosis within 12 months prior to the first claim were identified in the HealthCore Integrated Research Database between 1 November 2010 and 30 November 2013. PARTICIPANTS: 45 092 patients with NVAF were included. OUTCOMES: The proportion of OAC-treated patients was stratified by CHADS2 score. Treatment persistence was measured from OAC initiation to discontinuation, end of eligibility or end of study period (30 November 2014), whichever occurred first. RESULTS: Almost half of the patients (41.1%) received an OAC. The proportion treated differed slightly in baseline stroke risk (CHADS2<2: 39.8%; CHADS2=2 or 3: 42.4%; and CHADS2>3: 40.3%: p<0.001). Treated patients were slightly younger (70±12.2 vs 71±14.3 years; p<0.001), more likely male (59.7% vs 52.5%; p<0.001) and had a slightly elevated stroke risk (CHADS2: 2.03±1.3 vs 1.98±1.4; p<0.001) and a lower bleeding risk (HEMORR2HAGES: 2.55±1.8 vs 2.80±1.9; p<0.001) relative to untreated patients. Overall, patients with higher CHADS2 scores had higher HEMORR2HAGES scores. The mean follow-up was 2.25 years (2.25±0.85) and 72.7% of patients discontinued OACs; nearly 25% within 3 months and 55% within 12 months. The mean time to discontinuation was 255±249 days. CONCLUSIONS: The proportion of patients with NVAF who received OAC treatment was lower than previously reported and differed slightly by stroke risk. Patients with an elevated stroke risk had a higher bleeding risk, suggesting that clinicians may incorporate both in the treatment decision.

Post-traumatic stress symptoms and trauma exposure in youth with first episode bipolar disorder.

AIMS: To examine the prevalence of trauma exposure as well as the rates and effects of post-traumatic stress disorder (PTSD) in adolescents with bipolar disorder following a first manic episode. METHODS: Adolescents (12-18 years) with DSM-IV bipolar I disorder and experiencing their first manic or mixed episode were recruited. Participants underwent structured diagnostic interviews, completed the Trauma Symptom Checklist for Children (TSCC), and were prospectively evaluated using diagnostic, symptomatic and functional assessments over the course of 12 months. RESULTS: Seventy-six adolescents (14.9 +/- 1.7 years) completed the TSCC and 66% (50 individuals) reported exposure to traumatic events. Two (3%) subjects met DSM-IV criteria for PTSD, 11 (14%) had post-traumatic stress t-scores > or = 65, the threshold for clinically significant symptoms. Subjects with and without post-traumatic stress t-scores > or = 65 did not differ in demographic characteristics. When compared by t-score, TSCC subscores of the first episode bipolar adolescents were similar to normative data. Regression models incorporating TSCC subcomponents, did not predict syndromic recovery or recurrence or symptomatic recovery. CONCLUSIONS: Rates of PTSD were lower in this sample of bipolar adolescents at the time of their first hospitalization compared with rates in samples of bipolar adults. These differences coupled with the low incidence of PTSD and trauma symptoms in this young sample suggests that bipolar disorder may be a risk factor for the development of PTSD later in the course of illness or following recurrent affective episodes.
