Meaningful engagement of people living with cancer: Leveraging breast cancer survivors in a stigma reduction intervention in Tanzania.

Introduction: Cancer-related stigma is a key driver of advanced breast cancer stage in Sub-Saharan Africa (SSA). We developed and tested the impact of a breast cancer survivor-led Stigma reduction intervention (SRI) on stigma and treatment adherence of newly diagnosed patients with breast cancer in Tanzania.

Methods: Breast cancer survivors were trained on breast cancer knowledge and motivational interviewing.

Proportion of early-stage breast cancer at diagnosis in Ethiopia: a systematic review and meta-analysis.

Background: Breast cancer is the most common cancer-affecting women globally, with disproportionally high mortality rates in lower-income countries, including Ethiopia. The stage at diagnosis is a well-defined predictive system that determines the likelihood of breast cancer mortality. Early-stage breast cancer at diagnosis is associated with better treatment outcomes as compared with late stage.

Building Trust and Partnership with Black Pediatric Patients and their Caregivers.

Systemic racism embedded within the US health care system results in disproportionately worse health outcomes for Black pediatric patients and their caregivers. One meaningful mechanism through which these health disparities persist is through discriminatory treatment and anti-Black bias from clinicians. Strengthening care provided to Black pediatric patients and their caregivers requires that clinicians adopt culturally tailored communication strategies that promote health equity and counter racism.

Black patient perceptions of COVID-19 vaccine, treatment, and testing.

Context: The Presence for Racial Justice project leverages the Stanford Presence 5 framework to present anti-racism communication practices that promote clinician trust-building for Black patients in primary care. With the racial/ethnic disparities in COVID-19 infection rates, an assessment of Black patients' perspectives around COVID-19 care is required to promote health equity in current and future health crises. Objective: To compile clinician communication strategies for promotion of patient understanding and agency concerning Black patients' perceptions of COVID-19 vaccine, treatment and testing.

Syntactic modulation of rhythm in Australian pied butcherbird song.

The acoustic structure of birdsong is spectrally and temporally complex. Temporal complexity is often investigated in a syntactic framework focusing on the statistical features of symbolic song sequences. Alternatively, temporal patterns can be investigated in a rhythmic framework that focuses on the relative timing between song elements.

The Presence 5 for Racial Justice Framework for anti-racist communication with Black patients.

Objective: To identify communication practices that clinicians can use to address racism faced by Black patients, build trusting relationships, and empower Black individuals in clinical care.

Data Sources: Qualitative data (N = 112 participants, August 2020-March 2021) collected in partnership with clinics primarily serving Black patients in Leeds, AL; Memphis, TN; Oakland, CA; and Rochester, NY.

Study Design: This multi-phased project was informed by human-centered design thinking and community-based participatory research principles.

Evidence for Teaching in an Australian Songbird.

Song in oscine birds (as in human speech and song) relies upon the rare capacity of vocal learning. Transmission can be vertical, horizontal, or oblique. As a rule, memorization and production by a naïve bird are not simultaneous: the long-term storage of song phrases precedes their first vocal rehearsal by months.

A single-cell atlas of the peripheral immune response in patients with severe COVID-19.

There is an urgent need to better understand the pathophysiology of Coronavirus disease 2019 (COVID-19), the global pandemic caused by SARS-CoV-2, which has infected more than three million people worldwide. Approximately 20% of patients with COVID-19 develop severe disease and 5% of patients require intensive care. Severe disease has been associated with changes in peripheral immune activity, including increased levels of pro-inflammatory cytokines that may be produced by a subset of inflammatory monocytes, lymphopenia and T cell exhaustion.

A single-cell atlas of the peripheral immune response to severe COVID-19.

There is an urgent need to better understand the pathophysiology of Coronavirus disease 2019 (COVID-19), the global pandemic caused by SARS-CoV-2. Here, we apply single-cell RNA sequencing (scRNA-seq) to peripheral blood mononuclear cells (PBMCs) of 7 patients hospitalized with confirmed COVID-19 and 6 healthy controls. We identify substantial reconfiguration of peripheral immune cell phenotype in COVID-19, including a heterogeneous interferon-stimulated gene (ISG) signature, HLA class II downregulation, and a novel B cell-derived granulocyte population appearing in patients with acute respiratory failure requiring mechanical ventilation.

Temporal regularity increases with repertoire complexity in the Australian pied butcherbird's song.

Music maintains a characteristic balance between repetition and novelty. Here, we report a similar balance in singing performances of free-living Australian pied butcherbirds. Their songs include many phrase types.

Forensic discrimination of photocopy and printer toners II. Discriminant analysis applied to infrared reflection-absorption spectroscopy.

Copy toner samples were analyzed using reflection-absorption infrared microscopy (R-A IR). The grouping of copy toners into distinguishable classes achieved by visual comparison and computer-assisted spectral matching was compared to that achieved by multivariate discriminant analysis. For a data set containing spectra of 430 copy toners, 90% (388/430) of the spectra were initially correctly grouped into the classifications previously established by spectral matching.

Forensic discrimination of photocopy and printer toners I. The development of an infrared spectral library.

Microscopical reflection-absorption by infrared spectroscopy (R-A IR) was shown as a viable technique for analyzing the polymer resins contained in dry, black photocopy and printer toners. The sampling technique involves a heat transfer of the toner from a document to the reflective surface of aluminum foil followed by analysis by R-A IR. The technique is simple, fast, and readily available to most forensic laboratories.
