High-risk breast lesions (HRLs) are a group of heterogeneous lesions that can be associated with a synchronous or adjacent breast cancer and that confer an elevated lifetime risk of breast cancer. Management of HRLs after core needle biopsy may include close imaging and clinical follow-up or excisional biopsy to evaluate for cancer. This article reviews histologic features and clinical presentation of each of the HRLs, current evidence with regard to management, and guidelines from the American Society of Breast Surgeons and National Comprehensive Cancer Network. In addition, imaging surveillance and risk-reduction strategies for women with HRLs are discussed.Since its widespread introduction 30 years ago, screening mammography has contributed to substantial reduction in breast cancer-associated mortality, ranging from 15% to 50% in observational trials. It is currently the best examination available for the early diagnosis of breast cancer, when survival and treatment options are most favorable. However, like all medical tests and procedures, screening mammography has associated risks, including overdiagnosis and overtreatment, false-positive examinations, false-positive biopsies, and radiation exposure. Women should be aware of the benefits and risks of screening mammography in order to make the most appropriate care decisions for themselves.Artificial intelligence (AI) technology shows promise in breast imaging to improve both interpretive and noninterpretive tasks. AI-based screening triage may help identify normal examinations and AI-based computer-aided detection (AI-CAD) may increase cancer detection and reduce false positives. Risk assessment, quality assurance, and other workflow tasks may also be streamlined. AI adoption will depend on robust evidence of improved quality, increased efficiency, and cost-effectiveness. Reliance on AI will likely proceed through stages and will involve careful attention to its limitations to prevent overconfidence in its application.In an increasingly competitive and passionate health care environment, radiology advocacy is imperative, now more than ever. Arguably, it is particularly more crucial in the world of breast cancer, as we as a breast cancer community are tirelessly assembling to advocate for our patients on a variety of levels, whether it is including but not limited to, breast cancer screening, diagnosis, and treatment, access-to-care, education, or research funding. As breast radiologists, it is no longer simply enough to clock in our normal work hours; we must ALL make a concerted effort to vociferously advocate for our patients and profession.Breast cancer screening is a recognized tool for early detection of the disease in asymptomatic women, improving treatment efficacy and reducing the mortality rate. There is raised awareness that a "one-size-fits-all" approach cannot be applied for breast cancer screening. Currently, despite specific guidelines for a minority of women who are at very high risk of breast cancer, all other women are still treated alike. This article reviews the current recommendations for breast cancer risk assessment and breast cancer screening in average-risk and higher-than-average-risk women. Also discussed are new developments and future perspectives for personalized breast cancer screening.Contrast-enhanced mammography (CEM) is an emerging breast imaging technology that provides recombined contrast-enhanced images of the breast in addition to low-energy images analogous to a 2-dimensional full-field digital mammogram. Because most breast imaging centers do not use CEM at this time, a detailed overview of CEM implementation and performance is presented. Thereafter, the potential use of CEM for supplemental screening is discussed in detail, given the importance of this topic for the future of the CEM community. Diagnostic performance, safety, and cost considerations of CEM for dense breast tissue supplemental screening are discussed."Starting in Wuhan, China, followed quickly in the United States in January 2020, an outbreak of a novel coronavirus, or COVID-19, escalated to a global pandemic by March. Significant disruptions occurred to breast imaging, including deferred screening mammography, triaging diagnostic breast imaging, and changes in breast cancer care algorithms. This article summarizes the effect of the global pandemic-and efforts to curtail its spread-on both breast cancer care and on breast imaging practices including effects on patients, clinical workflow, education, and research."Heat shock proteins (HSPs) are emerging as valuable potential molecular targets in breast cancer therapy owing to their diverse functions in cancer cells. This study investigated the potential role of heat shock protein 27 (HSP27, also known as HSPB1) in breast cancer through heat shock protein B8 (HSPB8). The correlation between HSP27 and HSPB8 was identified by using co-immunoprecipitation, immunoprecipitation, and SUMOylation assays. Through gain- and loss-of-function approaches in MCF-7 cells, the effect of HSP27 on HSPB8 expression, SUMOylation level, and protein stability of HSPB8, as well as on cell proliferation, migration, and stemness, was elucidated. A mouse xenograft model of breast cancer cells was established to verify the function of HSP27 in vivo. Results indicate that HSP27 and HSPB8 were highly expressed in breast cancer tissues and MCF-7 cells. HSP27 was also found to induce the SUMOylation of HSPB8 at the 106 locus and subsequently increased its protein stability, which resulted in accelerated proliferation, migration, and stemness of breast cancer cells in vitro along with increased tumor metastasis of breast cancer in vivo. However, these results could be reversed by the knockdown of HSPB8. Overall, HSP27 induces SUMOylation of HSPB8 to promote HSPB8 expression, thereby endorsing proliferation and metastasis of breast cancer cells. This study may provide insight for the development of new targets for breast cancer.In a patient with an old inferior myocardial infarct, the Q waves disappear when he develops left anterior fascicular block.
Postmenopausal women have an elevated risk of developing cardiovascular diseases, which can be counteracted by conventional exercise regimes or recreational football. Less is known about the impact of exercise programmes based on other team sports. Thus, we examined the effects of recreational team handball on aerobic performance, cardiorespiratory fitness and cardiometabolic health in untrained postmenopausal women.

Sixty-seven participants (age 68±6years, stature 157±6cm, body mass 67±10kg, fat mass 37±7%, VO
25.2±3.6mL/min/kg, Yo-Yo intermittent endurance level 1 test performance (YYIE1) 230±103m) with no previous experience of team handball were randomly allocated to either a team handball (THG, n=41) or a control (CG, n=26) group. THG performed 2-3 60-min training sessions per week for 16weeks. YYIE1 performance and cardiometabolic markers were evaluated at baseline and post-intervention.

Average attendance during recreational team handball training was 1.9±0.4 sessions per week, with mean heart .
Recreational team handball can be used to obtain moderate-to-vigorous aerobic intensities, and just 2 weekly 60-min team handball training sessions for 16 weeks can result in improvements in aerobic performance and in markers of cardiorespiratory fitness in postmenopausal women with no previous experience of the sport.Over the past century, governmental involvement in the delivery of health care has grown steadily through health policy initiatives and increased regulations. Traditionally, the involvement in this process for the orthopedic surgeon was minimal because they were focused primarily on direct patient care. These two pathways have met a crossroads, however, where it has now become necessary for the orthopedic surgeon to advocate on behalf of themselves and their patients to guide and influence the legislative and regulatory processes. This article reviews the background of orthopedic advocacy and discusses ways in which the interested surgeon can become involved.This article explores the current state of the residency match in 2020 with a focus on orthopedic surgery, analyzing the utility of current applicant screening methods in producing future generations of competent surgeons. Discussed are anticipated changes to the residency application process considering the COVID-19 pandemic and Step 1 becoming pass/fail in January 2022. Also explored are potential changes to improve the process for applicants and residency programs, such as identifying and using predictive factors of resident success in the applicant screening process, finding better ways to match applicants with programs, and increasing female and underrepresented minorities within orthopedics.Professional identity formation (PIF) of medical students encompasses how students learn to think, do, and act as physicians. A key component of PIF is socialization, which includes mentoring. Mentoring influences students' career specialty choice, while providing a safe and nurturing environment to form their own professional identities. Mentoring of medical students by orthopedic surgeons may increase interest in the specialty. Suggestions for utilizing mentoring for the PIF of medical students and to increase diversity in orthopedics are discussed.As effective surgeon educators, we must seek continual improvement, to be "better today than I was yesterday." This pursuit of personal and professional development requires self-awareness of a guiding purpose, and grit, the passion and perseverance to achieve long-term goals. Surgical training draws on an apprenticeship model, where progressive transfer of knowledge, responsibility, and autonomy occurs over time as trainees work with experienced surgeons. Educators should model personal responsibility and technical excellence and require both of their trainees. While training programs shift towards competency-based learning, educators must remember that we shape learners with the "hidden curriculum" and not just the facts we teach them.The growing epidemic of physician burnout suggests that a change is needed. Physician wellness is an ever-growing consideration, especially in orthopedic surgery, where the challenges to wellness are significant. This review provides many common sense wellness principles and solutions in four main components of wellness (physical, mental, emotional, and spiritual) interwoven with current research on the topic. Although directed to orthopedic surgeons, this guide can be applied to all physicians, because they are based on common human principles of wellness. Wellness is not created overnight, so wellness practices that increase the likelihood of experiencing wellness are encouraged.The number of patients undergoing joint replacement and preservation procedures continues to increase worldwide. Globally, there is no standardized educational pathway, training program, or recognized certification program for surgeons in these procedures. Development and implementation of new competency-based curricula to deliver specific educational events and resources may help trainees and practicing surgeons be able to perform these procedures more effectively and therefore improve patient outcomes in their respective countries. Ideally, a curriculum would be globally standardized and professionally designed to interactively meet the needs of surgeons. A competency-based approach with built-in assessment and evaluation processes is today's educational standard.
