Reproductive factors and risk of epithelial ovarian cancer: results from the Asia Cohort Consortium.

Background: There are scarce data on risk factors for epithelial ovarian cancer (EOC) in Asian populations. Our goal was to advance knowledge on reproductive -related risk factors for EOC in a large population of Asian women.

Methods: This study used pooled individual data from baseline questionnaires in 11 prospective cohorts (baseline years, 1958-2015) in the Asia Cohort Consortium.

Real-Time Electronic Patient Portal Use Among Emergency Department Patients.

Importance: Patients with inequitable access to patient portals frequently present to emergency departments (EDs) for care. Little is known about portal use patterns among ED patients.

Objectives: To describe real-time patient portal usage trends among ED patients and compare demographic and clinical characteristics between portal users and nonusers.

Epithelial ovarian cancer survival by race and ethnicity in an equal-access healthcare population.

Background: Previous studies in the general population observed that compared with non-Hispanic White women, Pacific Islander and Black women have higher age-adjusted mortality rates from epithelial ovarian cancer (EOC), while Asian American patients have lower mortality. We investigated whether race and ethnicity is associated with differences in EOC survival in a United States Military population where patients have equal access to healthcare.

Methods: This retrospective study included women diagnosed with EOC between 2001 and 2018 among Department of Defense beneficiaries.

Predation risk drives long-term shifts in migratory behaviour and demography in a large herbivore population.

Migration is an adaptive life-history strategy across taxa that helps individuals maximise fitness by obtaining forage and avoiding predation risk. The mechanisms driving migratory changes are poorly understood, and links between migratory behaviour, space use, and demographic consequences are rare. Here, we use a nearly 20-year record of individual-based monitoring of a large herbivore, elk (Cervus canadensis) to test hypotheses for changing patterns of migration in and adjacent to a large protected area in Banff National Park (BNP), Canada.

Racial and ethnic differences in tumor characteristics among endometrial cancer patients in an equal-access healthcare population.

Purpose: There are racial and ethnic differences in endometrial cancer incidence and mortality rates; compared with Non-Hispanic White women, Black women have a similar incidence rate for endometrial cancer, but their mortality is higher. Pacific Islander women may also have worse outcomes compared to their White counterparts. We assessed tumor characteristics and adjuvant therapy by racial and ethnic group among endometrial cancer patients treated within the Military Health System, an equal access healthcare organization.

Clinical and financial outcome impacts of comprehensive geriatric assessment in a level 1 geriatric emergency department.

Background: The aging population has led to an increase in emergency department (ED) visits by older adults who have complex medical conditions and high social needs. The purpose of this study was to assess if comprehensive geriatric evaluation and management impacted service utilization and cost by older adults admitted to the ED.

Methods: This is a retrospective matched case-control study at a level 1 geriatric ED (GED) from January 1, 2018-March 31, 2020.

Development and Validation of a Respiratory-Responsive Vocal Biomarker-Based Tool for Generalizable Detection of Respiratory Impairment: Independent Case-Control Studies in Multiple Respiratory Conditions Including Asthma, Chronic Obstructive Pulmonary Disease, and COVID-19.

Background: Vocal biomarker-based machine learning approaches have shown promising results in the detection of various health conditions, including respiratory diseases, such as asthma.

Objective: This study aimed to determine whether a respiratory-responsive vocal biomarker (RRVB) model platform initially trained on an asthma and healthy volunteer (HV) data set can differentiate patients with active COVID-19 infection from asymptomatic HVs by assessing its sensitivity, specificity, and odds ratio (OR).

Methods: A logistic regression model using a weighted sum of voice acoustic features was previously trained and validated on a data set of approximately 1700 patients with a confirmed asthma diagnosis and a similar number of healthy controls.

Racial/Ethnic Differences Among Tumor-Infiltrating Lymphocytes in Breast Cancer Tumors.

Purpose: Tumor-infiltrating lymphocytes (TILs) have emerged as a predictor of breast cancer treatment response and patient outcomes. Current studies investigating racial/ethnic differences in TILs and immune profiles in breast cancer offer varying results. Our study provides some preliminary data in the breast cancer tumor microenvironment where there is a paucity of information, from Asian and Native Hawaiian/Pacific Islander (NHPI) racial/ethnic groups, not well represented in the literature.

Two Cases of Mesonephric-like Carcinoma Arising From Endometriosis: Case Report and Review of the Literature.

Endometriosis is a common condition in reproductive age women that is defined as the presence of endometrial tissue (epithelial and/or stromal) outside the uterine corpus. While not a premalignant lesion, it is a condition with a potential for malignancy, especially in the ovaries. Notable endometriosis-associated neoplasms include clear cell carcinoma and endometrioid adenocarcinoma of the ovaries.

Racial and Ethnic Disparities in Rates of Invasive Second Breast Cancer Among Women With Ductal Carcinoma In Situ in Hawai'i.

Importance: Women with ductal carcinoma in situ (DCIS) may develop a subsequent invasive second breast cancer (SBC). Understanding the association of racial and ethnic factors with the development of invasive SBC may help reduce overtreatment and undertreatment of women from minority groups.

Objective: To evaluate risk factors associated with developing invasive ipsilateral SBC (iiSBC) and invasive contralateral SBC (icSBC) among women with an initial diagnosis of DCIS who are from racial and ethnic minority populations.

Racial/ethnic differences in anthropometric and hormone-related factors and endometrial cancer risk: the Multiethnic Cohort Study.

Background: Anthropometric and hormone-related factors are established endometrial cancer risk factors; however, little is known about the impact of these factors on endometrial cancer risk in non-White women.

Methods: Among 110,712 women participating in the Multiethnic Cohort (MEC) Study, 1150 incident invasive endometrial cancers were diagnosed. Hazard ratios (HRs) and 95% confidence intervals (CIs) for associations with endometrial cancer risk for race/ethnicity and for risk factors across racial/ethnic groups were calculated.

The Implementation of an Emergency Medicine Telehealth System During a Pandemic.

Background: In March of 2020, the World Health Organization declared coronavirus disease 2019 (COVID-19)-a disease caused by a novel coronavirus-a pandemic, and it continued to spread rapidly in the community. Our institution implemented an emergency medicine telehealth system that sought to expedite care of stable patients, decrease provider exposure to COVID-19, decrease overall usage rate of personal protective equipment, and provide a platform so that infected or quarantined physicians could continue to work. This effort was among the first to use telehealth to practice emergency medicine in the setting of a pandemic in the United States.

Cross-Cancer Genome-Wide Association Study of Endometrial Cancer and Epithelial Ovarian Cancer Identifies Genetic Risk Regions Associated with Risk of Both Cancers.

Background: Accumulating evidence suggests a relationship between endometrial cancer and ovarian cancer. Independent genome-wide association studies (GWAS) for endometrial cancer and ovarian cancer have identified 16 and 27 risk regions, respectively, four of which overlap between the two cancers. We aimed to identify joint endometrial and ovarian cancer risk loci by performing a meta-analysis of GWAS summary statistics from these two cancers.

SeMSA: a compact super absorber optimised for broadband, low-frequency noise attenuation.

The attenuation of low-frequency broadband noise in a light, small form-factor is an intractable challenge. In this paper, a new technology is presented which employs the highly efficient visco-thermal loss mechanism of a micro-perforated plate (MPP) and successfully lowers its frequency response by combining it with decorated membrane resonators (DMR). Absorption comes from the membranes but primarily from the MPP, as the motion of the two membranes causes a pressure differential across the MPP creating airflow through the perforations.

A fight-and-flight for life: A rare case of advanced cervical cancer in pregnancy.

Background: Advanced cervical cancer during pregnancy is an extremely rare event. We describe a case of at least stage IIIB cervical squamous cell carcinoma during pregnancy. This may possibly represent the longest gestation from time of diagnosis to delivery in a case of advanced cervical cancer, with potentially the most advanced gestational age at delivery and a relatively favorable outcome in the current literature.

Completeness of salpingectomy intended for ovarian cancer risk reduction.

Background: Prophylactic salpingectomy has been heavily promoted based on the theory that serous tubal intraepithelial carcinoma is a precursor lesion for serous ovarian carcinoma. However, the validity of prophylactic salpingectomy has yet to be proven through adequate research. The purpose of this study is to evaluate the completeness of salpingectomy intended for ovarian cancer risk reduction.

Myocardial Infarction in the Neonate Without Coronary Artery Occlusion and Structurally Normal Heart: A Report of 2 Cases in Twin Pregnancies and Review of the Literature.

Myocardial infarction (MI) is a common diagnosis in the adult population and is associated with coronary artery atherosclerosis. However, it is an unusual diagnosis in the pediatric population, especially in the neonatal period. The authors present 2 autopsy cases of MI in newborn babies of twin pregnancies with normal heart and coronary arteries.

Raman-Enhanced Spectroscopy Distinguishes Anal Squamous Intraepithelial Lesions in Human Immunodeficiency Virus-Serodiscordant Couples.

HIV-positive individuals are at increased risk for precancerous anal squamous intraepithelial lesions (SILs). Anal cytology and digital rectal examination are performed as screening tools, but extensive training and appropriate instruments are required to follow up on an abnormal anal cytology. Thus, novel approaches to SIL evaluation could improve better health care follow-up by efficient and timely diagnosis to offer treatment options.

Clinical Cybersecurity Training Through Novel High-Fidelity Simulations.

Background: Cybersecurity risks in health care systems have traditionally been measured in data breaches of protected health information, but compromised medical devices and critical medical infrastructure present risks of disruptions to patient care. The ubiquitous prevalence of connected medical devices and systems may be associated with an increase in these risks.

Objective: This article details the development and execution of three novel high-fidelity clinical simulations designed to teach clinicians to recognize, treat, and prevent patient harm from vulnerable medical devices.

Randomized controlled trial evaluating the utility of urine HPV DNA for cervical cancer screening in a Pacific Island population.

Background: Non-invasive, self-collection sampling methods for human papillomavirus (HPV) DNA detection have the potential to address logistical and cultural barriers to Pap screening, particularly in under resourced settings such as Yap state in the Federated States of Micronesia - a population with low levels of screening and high incidence of cervical cancer.

Methods: A randomized controlled trial was conducted among adult women in Yap to compare cervical HPV DNA in self-collected urine and clinician-collected liquid cytology. Adult women aged 21-65 (n=217) were randomized by the order of sample collection.

Human Papillomavirus-16 DNA Quantitation Differentiates High-Grade Anal Neoplasia.

Due to their higher rates of anal dysplasia/cancer, human immunodeficiency virus (HIV)-positive individuals are recommended to undergo anal dysplasia screening, which consists of anal cytology (AC) and high resolution anoscopy (HRA) with anal biopsy (AB) after abnormal AC result. However, AC variability limits its usefulness. Our objective was to evaluate human papillomavirus (HPV)-16 DNA quantitation as part of the screening algorithm.

National Survey of Emergency Physicians Concerning Home-Based Care Options as Alternatives to Emergency Department-Based Hospital Admissions.

Background: Emergency departments (EDs) in the United States play a prominent role in hospital admissions, especially for the growing population of older adults. Home-based care, rather than hospital admission from the ED, provides an important alternative, especially for older adults who have a greater risk of adverse events, such as hospital-acquired infections, falls, and delirium.

Objective: The objective of the survey was to understand emergency physicians' (EPs) perspectives on home-based care alternatives to hospitalization from the ED.
