AI Article Synopsis
- This study investigated febrile neutropenia (FN) in Mexican adults with acute leukemia undergoing chemotherapy, revealing that 74 out of 95 patients experienced FN episodes.
- The majority of FN cases had a clear infection source, with urinary tract infections, bacterial sinusitis, and pneumonia being the most prevalent, and Gram-negative bacteria identified as the leading pathogens.
- Antimicrobial prophylaxis significantly reduced the risk of FN, while invasive fungal infections were linked to higher mortality rates within 30 days.
Article Abstract
Background: Few studies regarding infectious causes of febrile neutropenia (FN) in Mexico are available.
Aims: We aimed to describe clinical and microbiological characteristics of FN episodes during induction chemotherapy in adults with acute leukemia.
Methods And Results: This retrospective cohort from a Mexican tertiary care center included adults with newly diagnosed acute leukemia between January 2014, and December 2018. Clinical and microbiological characteristics were summarized using descriptive statistics. Univariate analyses for associations between clinical characteristics and FN and/or death were made; logistic regression analysis was performed to assess relationships with FN. Kaplan-Meier survival estimates were modeled for antimicrobial prophylaxis and FN. Ninety-five patients were included. Median age was 28 (IQR 20-43), 49 (52%) were males, and 74 (78%) developed FN (74/95). Among these, 98% had an identified source of infection (73/74) and 65% had >1. Common infections were urinary tract infection (24%), bacterial sinusitis (20%), and bacterial pneumonia (19%). Gram-negatives were the most frequently isolated microorganisms (69%), followed by Gram-positives (21%), and fungi (9%). Antimicrobial prophylaxis was inversely associated with FN (aOR = 0.07, CI 0.008-0.060, p = 0.02). Invasive fungal diseases were associated with 30-day mortality (aOR = 9.46, 95% CI 1.66-54.05).
Conclusion: Infections caused 98% of the FN episodes. Gram-negative bacteria are the most common pathogens.

Background: Randomized clinical trials have shown that semaglutide is associated with a clinically relevant reduction in body weight and a lower risk of adverse cardiovascular events in those who are overweight or obese with a history of cardiovascular disease but no diabetes. The objective of this study was to assess the cost-effectiveness of semaglutide for this indication.
Methods: A decision analytic Markov model was used to compare the lifetime benefits and costs of semaglutide 2.

This study sought to compare bacterial abundance and diversity in milk and feces of healthy lactating women with patients suffering from lactation mastitis, explore the pathogenesis of lactation mastitis, and develop new ideas for its treatment and prevention from a microbiological perspective. A total of 19 lactating mastitis patients and 19 healthy lactating women were recruited. Milk and fecal Specimens were obtained from both groups, and microbial community structure was analyzed using 16S rRNA gene sequencing.

Metformin, a widely used antidiabetic medication, has emerged as a promising broad-spectrum antiviral agent due to its ability to modulate cellular pathways essential for viral replication. By activating AMPK, metformin depletes cellular energy reserves that viruses rely on, effectively limiting the replication of pathogens such as influenza, HIV, SARS-CoV-2, HBV, and HCV. Its role in inhibiting the mTOR pathway, crucial for viral protein synthesis and reactivation, is particularly significant in managing infections caused by HIV, CMV, and EBV.
