Non ‐pneumophila Legionella species pneumonia with orange‐coloured sputum

We report a case of the orange-coloured sputum and bronchoalveolar lavage fluid and the detailed medical interview about recent gardening activity and exposure to compost or potting mix, which might be signs for rapid diagnosis of non-pneumophilaLegionella species pneumonia with a negative urinary antigen test. AbstractWe herein report an immunocompromised patient familiar with gardening admitted to our hospital suffering from severe pneumonia caused byLegionella longbeachae. We suspected non-pneumophilaLegionella species pneumonia because of gardening habits, the negative urine antigen test and the non-significant Gram staining results of orange-coloured sputum. The pathogen was identified using mass spectrometry analysis of bronchoalveolar lavage fluid. It is important to perform the medical interview carefully, noting the colour of sputum and gardening habits, for diagnosis and targeted therapy of non-pneumophilaLegionella species pneumonia, even if the urineLegionella antigen test is negative.

(TOKYO) — Almost overnight, Japan has become a stunning, and somewhat mysterious, coronavirus success story. Daily new COVID-19 cases have plummeted from a mid-August peak of nearly 6,000 in Tokyo, with caseloads in the densely populated capital now routinely below 100, an 11-month low. The bars are packed, the trains are crowded, and the mood is celebratory, despite a general bafflement over what, exactly, is behind the sharp drop. Japan, unlike other places in Europe and Asia, has never had anything close to a lockdown, just a series of relatively toothless states of emergency. Some possible factors in Japan’...

ConclusionsThis study suggests PD-L1 status was not an independent prognostic factor in recurrent/metastatic RCC during the study period because PD-L1 positivity was associated with poor prognostic factors, especially MSKCC risk status.

From personal to structural, racism may be understood as an endemic public health threat with crisis-level effects. Mindfulness practices, originating from numerous cultures and spiritual traditions, are an active area of scientific investigation for health and other benefits. Mindfulness is often studied for its internal effects in individuals. However, many important research questions remain underexplored. For example, how might mindfulness practices be applied to disrupt bias and minimize racism ’ s harms? How might the science of mindfulness be directed toward further exploring their external, interpersonal, and...

This study aimed to evaluate the association between work-related changes caused by COVID-19 and psychological distress among Japanese workers. The study was conducted from August 25 to September 30, 2020. The participants were 15,454 employees who were registered as panelists with an online survey company. The Kessler psychological distress scale with a 13-point cutoff was used to measure psychological distress. Multiple logistic regression was performed. Of the respondents, 8.9% were evaluated as having severe psychological distress. Among five examined work-related changes, being laid off and changing jobs (adjusted odd...

K. Decker The rapid identification of Legionella pneumonia is essential to optimize patient treatment and outcomes, and to identify potential public health risks. Previous studies have identified clinical factors which are more common in Legionella than non-Legionella pneumonia, and scores have been developed to assist in diagnosing cases. Since a Legionella pneumonia outbreak at VA Pittsburgh in 2012, nearly all patients with pneumonia have been tested for Legionella. The purpose of this study was to evaluate distinguishing characteristics between Legionella and non-Legionella pneumonia with the application of univers...

Conclusions This investigation into a probable outbreak provides evidence of transmission of psittacosis in one or more office workers with no direct bird contact. In light of this clinicians and public health professionals should be aware of the possibility of psittacosis in cases of severe respiratory illness reporting no overt bird contact and consider it on their list of differential diagnoses in situations where indirect exposure to birds is possible, but not necessarily obvious. Competing Interests The authors have declared that no competing interests exist. Corresponding Author John Mair-Jenkins: john.mairjenkins...

ConclusionCharacteristics of L. longbeachae pneumonia are broadly similar to those reported for community‐acquired pneumonia from a variety of other populations, except for the spring/summer seasonality.
