Laboratory studies on a group of 20 patients from the Rio Negro Valley, Colombia selected for detailed study showed that 14 gave antibody reactions on immunoassay consistent with Trypanosoma cruzi or T. rangeli infections. Four were diagnosed as having T. rangeli infection, 4 had mixed infections and 6 were infected with T. cruzi alone. Immunoprecipitation analysis showed that sera from T. cruzi-infected patients recognized a similar range of trypomastigote-derived polypeptides as sera from patients in Brazil, and all of the Colombian sera reacted with the 160 kiloDalton (kDa) polypeptide associated with active infection. Although sera from patients with T. rangeli infection alone gave a positive immunofluorescence or ELISA reaction with T. rangeli, they failed to bind to parasite polypeptides by either immunoprecipitation or Western blotting. Intriguingly, sera from patients with mixed infections consistently gave a stronger, but qualitatively similar, binding reaction in immunoprecipitation and Western blotting compared to sera from patients infected with T. cruzi alone.

Glomerular filtration rate (GFR) as a marker of kidney function is important in health and disease management because decreased kidney function is associated with all-cause and cardiovascular mortality, progression of kidney disease, predisposition to acute kidney injury (AKI), and for drug dosage modification. While measured glomerular filtration rate (mGFR) is acknowledged as the most accurate method for evaluating kidney function, it is at present not feasible to be applied in the clinical arena. Estimated glomerular filtration rate (eGFR) is preferred due to its convenience, cost-effectiveness, and seamless integration into standard clinical practice for kidney function evaluation.

Background: Primary aldosteronism (PA) is the leading surgically treatable cause of hypertension, with adrenalectomy as the definitive treatment for unilateral PA (UPA). However, some patients have persistent hypertension after surgery. This study aims to identify preoperative factors affecting surgical outcomes and develop a predictive model for postoperative hypertension resolution.

Objective: Colorectal cancer (CRC) is a common cancer, with chemotherapy as its major therapy. Nutritional status (NS) and adipokines implicated in CRC. We explored the impacts of NS indicators (hemoglobin, albumin, and prealbumin) and serum adipokine (visfatin, adiponectin, and resistin) level on chemotherapy efficacy in late-stage CRC patients.

Context: Phosphate homeostasis was compromised in tumor-induced osteomalacia (TIO) due to increased fibroblast growth factor 23 (FGF23) secretion. Nevertheless, the glucose metabolic profile in TIO patients has not been investigated.
Objectives: This work aimed to clarify the glucose metabolic profiles in TIO patients and explore their interaction with impaired phosphate homeostasis.
Valproic acid-induced hyperammonemia with encephalopathy in adults: A meta-analysis.
Int J Clin Pharmacol Ther
January 2025
Objective: Valproic acid, frequently prescribed for neurological and psychiatric disorders, can cause hyperammonemia (HA). This retrospective study aimed to investigate the association among the basic characteristics, comorbidities, co-medications, and risk of HA in patients receiving valproic acid.
Materials And Methods: We compared groups with and without HA using data collected from the medical records of adults undergoing valproic acid monitoring between January 1, 2019, and December 31, 2021.
