Article Synopsis
- Patients with immunodeficiency are at a higher risk of developing certain cancers, particularly mature lymphoid neoplasms and lymphoproliferative disorders.
- A 50-year-old woman on immunosuppressive therapy for dermatomyositis presented with swollen lacrimal glands, weight loss, and night sweats, leading to an elective biopsy.
- Post-surgery, she experienced acute abdominal issues that revealed multiple organ lesions and ultimately led to a diagnosis of polymorphic B-lymphoproliferative disorder resembling lymphomatoid granulomatosis, a rare condition linked to immunosuppression.
Background: There is limited evidence from antimicrobial stewardship programmes in less-resourced settings. This study aimed to improve the quality of antibacterial prescriptions by mitigating overuse and promoting the use of narrow-spectrum agents in intensive care units (ICUs) in a middle-income country.
Methods: We established a quality improvement collaborative (QIC) model involving nine Argentine ICUs over 11 months with a 16-week baseline period (BP) and a 32-week implementation period (IP).
Tropical rainforests exhibit a rich repertoire of spatial patterns emerging from the intricate relationship between the microscopic interaction between species. In particular, the distribution of vegetation clusters can shed much light on the underlying process that regulates the ecosystem. Analyzing the distribution of vegetation clusters at different resolution scales, we show the first robust evidence of scale-invariant clusters of vegetation, suggesting the coexistence of multiple intertwined scales in the collective dynamics of tropical rainforests.

The oil slick was predominantly displaced northward along the coastline, driven by prevailing currents and winds in the region. The weathering analysis revealed that the removal of oil was mainly due to evaporation (28%) and beaching processes (70%) within 96 h after the initial release.

Its pathogenesis lies in the TTR gene mutation, and the Val50Met mutation is the most frequent. Patients have significant differences in the onset and severity of clinical presentation according to their country of origin.
