Diffuse Alveolar Hemorrhage as the initial Presentation of Systemic Lupus Erythematous Possibly Triggered by Rhogam Injection in a 24-year-old Pregnant Woman; a case report.

Diffuse Alveolar Hemorrhage (DAH) is an uncommon and potentially life-threatening occurrence in systemic lupus erythematous (SLE), involving bleeding into the alveolar space caused by the disruption of the alveolar-capillary basement membrane. We present a 24-year-old Persian woman with a complaint of progressively worsening shortness of breath following the administration of intramuscular-Rhogam after 3 days. According to her worsening clinical condition, the pregnancy was terminated.

Purification of arsenic-contaminated drinking water by Fe-Al-CO layered double hydroxide derived from secondary aluminum dross: adsorption and stabilization studies.

This study aims to utilize secondary aluminum dross waste to synthesize Fe-Al layered double hydroxide (Fe-Al LDH) for efficient adsorption of arsenic from drinking water. The synthesis process was based on a multi-step hydrometallurgical approach, in which the aluminum content in the waste was first converted to sodium aluminate. This was followed by the transformation into Fe-Al LDH through a series of processes, including gelation, sol formation, simultaneous precipitation, and aging.

Evaluation of hematological markers as prognostic tools in rheumatoid arthritis.

Background: Reducing inflammation is central to the management of RA. However, commonly used markers such as CRP and ESR, along with the DAS-28 score, have shown limitations. Hematologic indices, such as platelet-lymphocyte ratio (PLR), lymphocyte-monocyte ratio (LMR), and neutrophil-lymphocyte ratio (NLR), show potential as reliable indicators of inflammation in RA.

The safety and efficacy of pRESET stent retriever for treatment of thrombo-embolic stroke; a systematic review and meta-analysis.

Background: The pRESET stent retriever is a self-expanding nitinol stent designed for mechanical thrombectomy in cases of large vessel occlusion during acute ischemic stroke. This systematic review and meta-analysis synthesize the available evidence on the safety and efficacy of the pRESET device.

Methods: This is a systematic review and meta-analysis study conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA).
