ObjectiveThis study aimed to compare the relative physical recovery and symptoms after SARS-CoV-2 infection between groups confirmed positive or negative to early strains of COVID-19.MethodsA prospective, longitudinal cohort study compared outcomes of metropolitan adults polymerase chain reaction-tested for COVID-19 between March and November 2020 in Western Australia. Control matching was attempted: inpatients (gender, age) and ambulatory clinic (gender, age, asthma, chronic pulmonary disease).

Purpose: Brain metastases (BMs) are a common source of morbidity and mortality. Guidelines do not advise brain surveillance for locally advanced non-small cell lung cancer (LA-NSCLC). We describe the incidence, time to development, presentation, and management of BMs after definitive chemoradiotherapy (CRT).

Background: Improvements in therapies have led to an increasing number of long-term survivors of brain metastases. The present series compares a population of 5-year survivors of brain metastases to a generalized brain metastases population to assess for factors attributable to long-term survival.

Methods: A single institution retrospective review was performed to identify 5-year survivors of brain metastases who received stereotactic radiosurgery (SRS).

Purpose: Life expectancy continues to increase for patients with brain metastases treated with stereotactic radiosurgery (SRS). The present study sought to retrospectively analyze brain metastasis patients who have survived 2 years or more, and assess for what factors may predict for a final brain metastasis velocity (BMV) of zero.

Methods: This was a single-institution retrospective study of 300 patients treated with SRS from 2001 to 2019 for brain metastases who survived greater than 2 years after first SRS.

Background: Radial scars (RS) and complex sclerosing lesions (CSL) are breast radiologic findings described as small, stellate lesions causing architectural distortion. This can mimic malignancy. Core needle biopsy (CNB) is often performed.

Background: Participant enrolment, assessment and/or delivery of intervention in many clinical trials during the COVID-19 pandemic were severely impacted by public health measures limiting physical contact. This report describes the lessons learned in completing a repeated measures cohort study involving suspected and confirmed COVID-19 survivors at three sites in Perth, Western Australia.

Main Body: An observational analysis of the conduct and data completeness results of the LATER-19 trial.

Background: The American College of Surgeons Oncology Group Z1071 trial in 2013 demonstrated the fesability of sentinel lymph node biopsy in clinically node-positive patients following neoadjuvant chemotherapy. The goal of this study was to determine the continued impact of this study on our practice pattern.

Materials And Methods: This is a retrospective review of institutional changes in the management of axillary nodal disease following the publication of Z1071.

Background: Triple-negative breast cancers (TNBCs), accounting for approximately 15% of breast cancers, lack targeted therapy. A hallmark of cancer is metabolic reprogramming, with one-carbon metabolism essential to many processes altered in tumor cells, including nucleotide biosynthesis and antioxidant defenses. We reported that folate deficiency via folic acid (FA) withdrawal in several TNBC cell lines results in heterogenous effects on cell growth, metabolic reprogramming, and mitochondrial impairment.

Cancer cells experience unique and dynamic shifts in their metabolic function in order to survive, proliferate, and evade growth inhibition in the resource-scarce tumor microenvironment. Therefore, identification of pharmacological agents with potential to reprogram cancer cell metabolism may improve clinical outcomes in cancer therapy. Cancer cells also often exhibit an increased dependence on the process known as autophagy, both for baseline survival and as a response to stressors such as chemotherapy or a decline in nutrient availability.

Exploring informal components of clinical reasoning, we argue that they need to be understood via the analysis of professional wisdom. Wise decisions are needed where action or insight is vital, but neither everyday nor expert knowledge provides solutions. Wisdom combines experiential, intellectual, ethical, emotional and practical capacities; we contend that it is also more strongly social than is usually appreciated.

Reasoning and judgement in health care entail complex responses to problems whose demands typically derive from several areas of specialism at once. We argue that current evidence- or value-based models of health care reasoning, despite their virtues, are insufficient to account for responses to such problems exhaustively. At the same time, we offer reasons for contending that health professionals in fact engage in forms of reasoning of a kind described for millennia under the concept of wisdom.

Despite the identification of risk factors for sudden infant death syndrome (SIDS) and decreased SIDS rates in many countries, there is still no coherent, widely accepted, mechanistic explanation for SIDS. As an extension of our work on the infectious aetiology of SIDS, we have explored the prediction that infectious agents might reach susceptible infants and babies, via particular sources of food. In this ecological study, we demonstrated significant correlations between SIDS rates and exposure to meat from some sources, and we propose that more detailed studies be carried out.
