Luis J Jara, Gabriela Medina, Polita Cruz-Cruz, Javier Olivares-Rivera, Carolina Duarte-Salazar, Miguel A Saavedra
Obstetric antiphospholipid syndrome (Obs-APS) is one of the most commonly identified causes of recurrent pregnancy loss and its accurate diagnosis is a requirement for optimal treatment. Some patients do not fulfill the revised Sapporo classification criteria, the original APS classification criteria, and are considered to be non-criteria Obs-APS. In these patients with non-criteria, there is controversy about their inclusion within the spectrum of APS and eventually their treatment as having Obs-APS. A subset of patients may also have clinical characteristics of Obs-APS even though lupus anticoagulant (LA), anticardiolipin antibodies, and anti-β2-glycoprotein I (aβ2GPI) antibodies are consistently negative...

BACKGROUND: Pulmonary infiltrates (PIs) detected in patients with non-Hodgkin lymphoma (NHL) may present a diagnostic challenge due to their wide differential diagnosis, including infection, pulmonary lymphoma and immunochemotherapy-associated pulmonary toxicity. OBJECTIVES: To characterize therapy-associated PIs by positron emission tomography/computed tomography (PET/CT) imaging. METHODS: We conducted a historical analysis of fluorodeoxyglucose-PET/CT (18F-FDG-PET/CT) PIs in NHL patients treated with combined immunochemotherapy including rituximab...

BACKGROUND: Israel is a country with a sunny climate; however, vitamin D deficiency and insufficiency are common findings in certain populations whose exposure to sunlight is limited. Medical residency is known for long indoor working hours, thus theoretically limiting the opportunities for sun exposure. OBJECTIVES: To evaluate whether the vitamin D status among residents in a single medical center in Tel Aviv is below the normal range. METHODS: Forty-six residents (28 females, 18 males, average age 33...

A foodborne illness outbreak involving an elite sports team was investigated by a public health unit in Sydney, Australia. An epidemiological association was established between gastrointestinal illness and the consumption of food supplied by an external caterer, with a lamb meal most strongly associated with illness. Genetically identical Salmonella isolates were identified from clinical specimens, residual food items, and an environmental swab taken from the catering premises. The training schedule and other club operations were significantly affected by this outbreak...

Aspergillus terreus is an emerging opportunistic fungal pathogen that causes invasive aspergillosis in immunocompromised individuals. The main risk group of individuals for this organism is leukopenic patients, individuals having cancers, bone marrow transplant persons and those who have immunological disorders. The lack of early diagnostic marker for A. terreus and intrinsic resistance to Amphotericin B, further limits the successful therapy of A. terreus-associated infections. The germination of inhaled conidia is the key step to establish successful invasion in host tissues or organs...

Growth differentiation factor 11 (GDF11), a TGF-beta superfamily member, is highly homologous to myostatin and essential for embryonic patterning and organogenesis. Reports of GDF11 effects on adult tissues are conflicting, with some describing anti-aging and pro-regenerative activities on the heart and skeletal muscle while others opposite or no effects. Herein, we sought to determine the in vivo cardiac and skeletal muscle effects of excess GDF11. Mice were injected with GDF11 secreting cells, an identical model to that used to initially identify the in vivo effects of myostatin...

The keratin filament cytoskeleton is vital to the normal function of epithelial cells. It provides structural support and regulates different aspects of cell metabolism. Mutations in keratins 5 and 14 cause a skin fragility disorder, epidermolysis bullosa simplex (EBS). Patients with severe EBS have an increased cumulative risk for basal cell carcinoma. In this study, we tested how keratin 5 and 14 mutant EBS patient-derived keratinocytes behave in the face of two different types of stressors that are able to induce cell death: ionizing radiation and cytokines TNF-α and TRAIL...
