Hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative breast cancer is defined by the presence of the estrogen receptor and/or the progesterone receptor and the absence of HER2 gene amplification. HR-positive/HER2-negative breast cancer accounts for 65%–70% of all breast cancers, and incidence increases with increasing age. Treatment varies by stage, and endocrine therapy is the mainstay of treatment in both early stage and late-stage disease. Combinations with cyclin-dependent kinase 4/6 inhibitors have reduced distant recurrence in the early stage setting and improved overall survival in the metastatic setting. Chemotherapy is used based on stage and tumor biology in the early stage setting and after endocrine resistance for advanced disease. New therapies, including novel endocrine agents and antibody-drug conjugates, are now changing the treatment landscape. With the availability of new treatment options, it is important to define the optimal sequence of treatment to maximize clinical benefit while minimizing toxicity. In this review, the authors first discuss the pathologic and molecular features of HR-positive/HER2-negative breast cancer and mechanisms of endocrine resistance. Then, they discuss current and emerging therapies for both early stage and metastatic HR-positive/HER2-negative breast cancer, including treatment algorithms based on current data.  相似文献

When hospitals first encountered coronavirus disease 2019 (COVID-19), there was a dearth of therapeutic options and nearly 1 in 3 patients died from the disease. By the summer of 2020, as deaths from the disease declined nationally, multiple single-center studies began to report declining mortality of patients with COVID-19. To evaluate the effect of COVID-19 on hospital-based mortality, we searched the Vizient Clinical Data Base for outcomes data from approximately 600 participating hospitals, including 130 academic medical centers, from January 2017 through December 2020. More than 32 million hospital admissions were included in the analysis. After an initial spike, mortality from COVID-19 declined in all regions of the country to under 10% by June 2020 and remained constant for the remainder of the year. Despite this, inpatient, all-cause mortality has increased since the beginning of the pandemic, even those without respiratory failure. Inpatient mortality has particularly increased in elderly patients and in those requiring intubation for respiratory failure. Since June 2020, COVID-19 kills one in every 10 patients admitted to the hospital with this diagnosis. The addition of this new disease has raised overall hospital mortality especially those who require intubation for respiratory failure.  相似文献

An increased number of patients is at risk of Candida spp. bloodstream infection (CBSI) in modern medicine. Moreover, the rising of antifungal resistance (AR) was recently reported. All consecutive CBSI occurred in our Hospital (consisting of 1,370 beds) between 2015 and 2018, were reviewed. For each case, Candida species, AR pattern, ward involved and demographic data of patients were recorded. Overall, 304 episodes of CBSI occurred, with a median (q1:first-,q3:third quartile) of 77 (71-82) CBSI/year. Over the years, a significant increase of CBSI due to C. albicans compared to non-albicans strains was recorded in medical wards (from 65% to 71%, p=0.030), while this ratio remained stable in others. An increase of resistant strains to multiple antifungals such as C. guillermondii was noticed in recent years (from 0% to 9.8%, p=0.008). Additionally, from 2015 to 2018 an increase in fluconazole-resistance was recorded in our Hospital (from 7.4% to 17.4%, p=0.025) and a slight increase in voriconazole-resistance (from 0% to 7% in 2018, p=0.161) was observed, while resistance to echinocandin and amphotericin B remained firmly below 2%.This study suggests a rapid spread of antifungal resistance in our Hospital; therefore, an appropriate antifungal stewardship programs is urgently warranted.  相似文献

BackgroundIn 2007, the Japanese Orthopedic Association established the term “Locomotive Syndrome” (LS) for the concept of locomotor organ dysfunction with potential loss of independence. The purpose of this study was to identify characteristics of LS and establish a diagnostic cut-off for the Geriatric Locomotive Function Scale (GLFS 25-p) for the Brazilian population.MethodsA cross-sectional observational study of the LOCOMOV Project cohort of independent outpatients aged ≥80 years was conducted. Questionnaires on functional status in Basic and Instrumental Activities of Daily Living (Katz and Lawton, respectively) and quality of life (WHOQOL-Bref) were applied, together with the Geriatric Locomotive Function Scale (GLFS 25-p) to identify individuals with LS. Mobility was assessed using the five-times sit-to-stand test, 4-m gait speed, two-step test, one-leg standing time with eyes open and hand-grip test. The data were analyzed using Student's t-test, the Chi–Square test, and multiple logistic regression (stepwise). The significance level was set at 0.05 (5%).ResultsA sample of 102 individuals with mean age of 87.3 (±4.2) years and predominantly female (73.5%) was assessed. We determined a cut-off score of 19 (sensitivity of 0.86 and specificity of 0.67) for diagnosis of LS, as assessed by the GLFS 25-p, and a high prevalence (55%) of the syndrome was found in the sample. In the multiple regression analysis, LS was directly associated with chronic pain (OR 22.24, 95%CI 3.13–157.87), use of a walking device (OR 17.121, 95%CI 1.94–150.49), and inversely associated with gait speed ≥0.8 m/s (OR 0.42, 95%CI 0.006–0.278), perception of good health (OR 0.153, 95%CI 0.029–0.799) and male gender (OR 0.086, 95%CI 0.0105–0.714).ConclusionThe LS in the oldest old proved a very common condition in this survey, especially in women, and was strongly associated with chronic pain, worse performance on physical tests and poor quality of life.  相似文献
