A Real Gut Punch: An Unexpected Diagnosis of Spontaneous Splenic Rupture.

Atraumatic or spontaneous splenic rupture is a rare but life-threatening complication of infectious mononucleosis. We present a case of a 26-year-old man presenting with a 1-week history of sharp epigastric and right upper quadrant pain, associated with malaise and subjective fever. Although initial findings were concerning for acute cholangitis, abdominal computed tomography angiography scan revealed splenic rupture.

Sevelamer-Induced Ischemic Enteritis.

Sevelamer, a nonabsorbable dietary phosphate binder, is essential for patients with renal impairment since hyperphosphatemia is associated with an increase in all-cause mortality. Sevelamer is generally well tolerated; however, it is rarely been documented to cause gastrointestinal mucosal injury by forming sevelamer crystals and depositing within the gastrointestinal walls. We present a 35-year-old man with end-stage renal disease on peritoneal dialysis who developed abdominal pain and hematochezia.

Virologic outcomes of antiretroviral therapy in patients with HIV-1 following bariatric surgery: A case series and review of the literature.

Background: Selection of an antiretroviral regimen for people living with HIV (PLWH) involves various clinical considerations, such as comorbidities, archived drug resistance mutations, concomitant medications, and potential drug interactions and side effects. Alterations in the surface area and pH of the gastrointestinal tract following bariatric surgery may alter absorption, antiretroviral pharmacokinetics and viral suppression. Data on the efficacy of antiretroviral (ARV) therapy in PLWH who have undergone bariatric surgery are limited or lacking for new antiretrovirals, such as dolutegravir and bictegravir.

Transcriptional pausing factor M1BP regulates cellular homeostasis by suppressing autophagy and apoptosis in eye.

During organogenesis cellular homeostasis plays a crucial role in patterning and growth. The role of promoter proximal pausing of RNA polymerase II, which regulates transcription of several developmental genes by GAGA factor or Motif 1 Binding Protein (M1BP), has not been fully understood in cellular homeostasis. Earlier, we reported that M1BP, a functional homolog of ZKSCAN3, regulates wingless and caspase-dependent cell death (apoptosis) in the Drosophila eye.
