Strain Induces Launch of Extracellular Vesicles simply by Trypanosoma cruzi Trypomastigotes.
A healthy, active woman in her 70s reported intermittent exertional dyspnoea for 2 months, notable during frequent open-water swimming. Symptoms were similar to an episode of travel-provoked pulmonary embolism 3 years prior. She denied chest pain, cough, fever, extremity complaints and symptoms at rest. Due to the COVID-19 pandemic, her healthcare system was using secure telemedicine to evaluate non-critical complaints. Cell Cycle inhibitor During the initial video visit, she appeared well, conversing normally without laboured breathing. An elevated serum D-dimer prompted CT pulmonary angiography, which identified acute lobar pulmonary embolism. After haematology consultation and telephone conversation with the patient, her physician prescribed rivaroxaban. Her symptoms rapidly improved. She had an uneventful course and is continuing anticoagulation indefinitely. The pandemic has increased the application of telemedicine for acute care complaints. This case illustrates its safe and effective use for comprehensive management of acute pulmonary embolism in the primary care setting.Two patients receiving oral etoposide therapy developed Pneumocystis jirovecii pneumonia during chemotherapy with significant lymphopenia without corticosteroid use. In this commentary we discuss cellular mechanisms by which etoposide induced CD4+ T lymphocyte dysfunction and reduced survival may lead to predisposition to P. jirovecii infection.A man in his early 40s with no significant vascular risk factors was managed within a period of 6 months for recurrent vascular events ischaemic stroke, transient ischaemic attack and isolated third nerve palsy. He was extensively investigated throughout the course of illness. The only potential aetiological factor identified was a positive janus kinase 2 (JAK 2) mutation after screening on account of mildly elevated platelet count noted during his most recent admission. Bone marrow aspiration confirmed essential thrombocythaemia. He was started on hydroxycarbamide and has remained relatively symptom free since then.This case reiterates the known associations between thrombosis and JAK 2 mutation even without overt myeloproliferative neoplasms. It also highlights the need for specialists in stroke to consider screening for JAK 2 mutation in a young patient with cryptogenic stroke with or without polycythemia or thrombocytosis.Molluscum contagiosum (MC) is a viral skin infection seen in children, sexually active adults and immunocompromised populations. It is usually a self-limiting illness that typically spontaneously resolves without therapeutic intervention. However, when the papules are extensive or refractory causing complications or aesthetic issues, multiple treatment modalities exist to relieve symptoms, limit spread and decrease the social stigma associated with visible lesions. Treatment is especially important in HIV/AIDS infected populations, where prevalence is estimated between 5% and 18% and susceptibility to larger, widespread and recalcitrant lesions involving atypical distributions is more common. We evaluated a 38-year-old woman with a history of AIDS (CD4+ T cell count less then 25 cells/µL) and poor adherence with antiretroviral therapy who presented with a 9-month history of persistent, progressively worsening facial and truncal umbilicated papules consistent with recalcitrant MC refractory to cidofovir injections. She was successfully treated with paclitaxel with complete resolution of the lesions after four cycles without adverse effects.Outside of SARS-CoV-2 vaccines, there is little positive outlook for the control of Covid-19 epidemic. Schematically, two antagonistic and extreme strategies have been proposed, zero-covid and herd immunity. Between the two, often oscillating measures, based on medical but also societal and political considerations, have been taken without any major effect on the course of the epidemic. Vaccines are a game-changer by providing a real opportunity to sustainably protect everyone against infection and eliminate the circulation of the virus. The Pfizer, Moderna and AstraZeneca vaccines, the three currently authorized in France, overall induce remarkable protection rates of 95 %, 94 % and 70 % respectively. The surprise came from that this efficacy was obtained after a rapid development, by targeting only the viral protein S as antigen, and by using the administration of expression vectors innovative in vaccinology, consisting of either messenger RNA or recombinant adenovirus. However, bringing the epidemic under control requires a well-organized mass vaccination campaign. It also requires careful monitoring of many parameters such as the occurrence of adverse events, duration of induced immunity, vaccine efficacy against emerging variants of SARS-CoV-2, interest or not of vaccinating people already infected, vaccination of immunocompromised patients. Vaccination must be accompanied by the maintenance of barrier measures and gestures and an amplification of clinical and biological investigations both to validate its effectiveness on the Covid-19 epidemic and to prepare for future developments in vaccinology.
To identify nurses' knowledge, perception and practice around urinalysis and asymptomatic bacteriuria (ASB) and to determine drivers of inappropriate urinalysis practice in an Australian hospital setting.

Undertaken in eight geriatric wards over four hospitals, a questionnaire inviting voluntary, anonymous participation tested nursing staff knowledge on urinalysis, recognition of urinary tract infection (UTI) and perception of the utility of urinalysis as a routine test on all ward admissions. A retrospective one-month audit was performed on admissions to a 32-bed geriatric ward.

132 of 220 (60%) distributed surveys were completed. Performing urinalysis on all new admissions was identified as routine practice by 89%, and with indwelling catheter change by 35% of respondents. Over-three-quarters believed that routine urinalysis on admission was useful practice and up to one-third believed urinalysis abnormalities warranted antibiotic prescribing. Dark urine (57.6%), foamy urine (55.3%) and vaginal itch (34.
