We pooled multiethnic data from four population-based studies and examined associations of menstrual and reproductive characteristics with breast cancer (BC) risk by tumor hormone receptor (HR) status [defined by estrogen receptor (ER) and progesterone receptor (PR)]. We estimated odds ratios and 95% confidence intervals using multivariable logistic regression, stratified by age (<50, ≥50 years) and ethnicity, for 5,186 HR+ (ER+ or PR+) cases, 1,365 HR− (ER− and PR−) cases and 7,480 controls. For HR+ BC, later menarche and earlier menopause were associated with lower risk in non-Hispanic whites (NHWs) and Hispanics, and higher parity and longer breast-feeding were associated with lower risk in Hispanics and Asian Americans, and suggestively in NHWs. Positive associations with later first full-term pregnancy (FTP), longer interval between menarche and first FTP and shorter time since last FTP were limited to younger Hispanics and Asian Americans. Except for nulliparity, reproductive characteristics were not associated with risk in African Americans. For HR− BC, lower risk was associated with later menarche, except in African Americans and older Asian Americans and with longer breast-feeding in Hispanics and Asian Americans only. In younger African Americans, HR− BC risk associated with higher parity (≥3 vs. 1 FTP) was increased fourfold in women who never breast-fed, but not in those with a breast-feeding history, suggesting that breast-feeding may mitigate the adverse effect of higher parity in younger African American women. Further work needs to evaluate why menstrual and reproductive risk factors vary in importance according to age and ethnicity. 相似文献

During the coronavirus disease 2019 (COVID-19) pandemic, principles from both clinical and public health ethics cue clinicians and healthcare administrators to plan alternatives for frail older adults who prefer to avoid critical care, and for when critical care is not available due to crisis triaging. This article will explore the COVID-19 Ethical Decision Making Framework, published in British Columbia (BC), Canada, to familiarize clinicians and policy makers with how ethical principles can guide systems change, in the service of frail older adults. In BC, the healthcare system has launched resources to support clinicians in proactive advance care planning discussions, and is providing enhanced supportive and palliative care options to residents of long-term care facilities. If the pandemic truly overwhelms the healthcare system, frailty, but not age alone, provides a fair and evidence-based means of triaging patients for critical care and could be included into ventilator allocation frameworks.

Septic shock after abortion is an important cause of global maternal mortality but is rarely encountered in developed countries. We describe a case of septic abortion with a novel associated pathogen: Neisseria meningitidis. A 30-year-old multiparous woman presented in septic shock after an incomplete spontaneous abortion. She received empiric antibiotics and vasopressors, underwent an urgent dilatation and curettage, and was admitted to the intensive care unit. Her blood cultures and endometrial tissue were positive for N. meningitidis. Antibiotics were adjusted based on culture, and the patient recovered. Septic shock requires prompt identification, antibiotic administration, and source control. Here, we identify an uncommon pathogen associated with septic abortion and highlight the importance of broad empiric and subsequent culture-guided antibiotic choice to ensure coverage. 相似文献
