<h3>Importance</h3> Video or telephone telemedicine can offer patients access to a clinician without arranging for transportation spending time in waiting room, but little is known about patient characteristics associated with choosing between office visits. <h3>Objective</h3> To examine visit vs the same primary care clinicians. <h3>Design, Setting, and Participants</h3> This cross-sectional study included data from 1 131 722 who scheduled appointment through Kaiser Permanente Northern...
Photonic integrated circuits (PICs) have emerged as a scalable platform for complex quantum technologies using photonic and atomic systems. A central goal has been to integrate photon-resolving detectors reduce optical losses, latency, wiring complexity associated with off-chip detectors. Superconducting nanowire single-photon (SNSPDs) are particularly attractive because of high detection efficiency, sub-50-ps timing jitter, nanosecond-scale reset time, sensitivity from the visible...
Conventional quantum key distribution (QKD) typically uses binary encoding based on photon polarization or time-bin degrees of freedom and achieves a capacity at most one bit per photon. Under photon-starved conditions the rate detection events is much lower than generation rate, because losses in long distance propagation relatively recovery times available single-photon detectors. Multi-bit arrival can be beneficial such situations. Recent security proofs indicate high-dimensional robust...
Racial disparities exist in outcomes after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.To evaluate the contribution of race/ethnicity SARS-CoV-2 testing, infection, and outcomes.Retrospective cohort study (1 February 2020 to 31 May 2020).Integrated health care delivery system Northern California.Adult plan members.Age, sex, neighborhood deprivation index, comorbid conditions, physiology indices, race/ethnicity; testing incidence positive test results;...
Background Although several clinical breast cancer risk models are used to guide screening and prevention, they have only moderate discrimination. Purpose To compare selected existing mammography artificial intelligence (AI) algorithms the Breast Cancer Surveillance Consortium (BCSC) model for prediction of 5-year risk. Materials Methods This retrospective case-cohort study included data in women with a negative mammographic examination (no visible evidence cancer) 2016, who were followed...
We propose a high-dimensional quantum key distribution (QKD) protocol that employs temporal correlations of entangled photons. The security the relies on measurements by Alice and Bob in one two conjugate bases, implemented using dispersive optics. show this dispersion-based approach is secure against collective attacks. protocol, which represents QKD analog pulse position modulation, compatible with standard fiber telecommunications channels wavelength division multiplexers. describe...
<h3>Objective</h3> Women have >50% greater lifetime risk of dementia than men but the role female-specific endocrine milieu is not well-understood. This study evaluates associations between indicators estrogen exposure from women9s reproductive period and in a large diverse population. <h3>Methods</h3> We evaluated 15,754 female members (29.9% nonwhite) Kaiser Permanente with clinical examinations health survey data 1964 to 1973 were as January 1, 1996. In midlife (mean age 51.1 years),...
Telemedicine visits can offer patients convenient access to a clinician, but it is unclear whether treatment differs from that with in-person or how often require follow-up.To examine physician prescribing and orders differ between telemedicine office visits, physicians conducting are more likely follow-up, associated health events.This cohort study included all who scheduled primary care appointments through the patient portal of large integrated delivery system newly implementing...
Abstract The aim of this study is to examine the association between patient characteristics and primary care telemedicine choice among integrated delivery system patients self-scheduling visits during COVID-19 pandemic. We used multivariate logistic regression video versus telephone sociodemographic technology access patient-initiated scheduled online from March October 2020. Among 978 272 patient-scheduled visits, 39% were visits. Patients Black or Hispanic race/ethnicity, living in low...
Breast arterial calcification (BAC), a common incidental finding in mammography, has been shown to be associated with angiographic coronary artery disease and cardiovascular (CVD) outcomes. We aimed (1) examine the association of BAC presence quantity hard atherosclerotic CVD (ASCVD) global CVD; (2) ascertain model calibration, discrimination reclassification ASCVD risk; (3) assess joint effect 10-year pooled cohorts equations risk on ASCVD.
Objective To examine clinical outcomes in patients receiving neoadjuvant chemoradiation for locally advanced rectal adenocarcinoma. Summary Background Data Preoperative radiation therapy, either alone or combination with 5-fluorouracil-based chemotherapy, has proven both safe and effective the treatment of cancer. However, data are lacking regarding which subgroups benefit from therapy terms decreased local recurrence increased survival rates. Methods A retrospective chart review was...
Field tests of a silicon photonics quantum-key-distribution encoder demonstrate scalable, affordable, high-speed solution to securing long-distance communication networks against intrusions from quantum computers.
Quantum key distribution (QKD) enables participants to exchange secret information over long distances with unconditional security. However, the performance of today's QKD systems is subject hardware limitations, such as those available nonclassical-light sources and single-photon detectors. By encoding photons in high-dimensional states, rate generating secure under these technical constraints can be maximized. Here, we demonstrate a complete time-energy entanglement-based system proven...
Post-transplant cyclophosphamide (PTCy) has significantly increased the successful use of haploidentical donors with a relatively low incidence graft-versus-host disease (GVHD). Given its increasing use, we sought to determine risk factors for GVHD after hematopoietic cell transplantation (haplo-HCT) using PTCy. Data from Center International Blood and Marrow Transplant Research on adult patients acute myeloid leukemia, lymphoblastic myelodysplastic syndrome, or chronic leukemia who...
associated with high COVID-19 rates, suggest that increased emphasis on the maintenance of optimal risk factor levels specified in American Heart Association's Life's Simple 7 guideline 5 and vigilance toward equity access to health care are warranted more than ever.
The risk of adverse events from ascending thoracic aorta aneurysm (TAA) is poorly understood but drives clinical decision-making.To evaluate the association TAA size with outcomes in nonsyndromic patients a large non-referral-based health care delivery system.The Kaiser Permanente Thoracic Aortic Aneurysm (KP-TAA) cohort study was retrospective at Northern California, fully integrated system insuring and providing for more than 4.5 million persons. Nonsyndromic regional safety net tracking...
