Background: Acute pancreatitis (AP) is a potentially life-threatening condition characterized by inflammation of the pancreas, which can lead to complications such as pancreatic necrosis. The modified computed tomography severity index (MCTSI) is a widely used tool for assessing the severity of AP, particularly the extent of pancreatic necrosis. The accurate and timely assessment of the necrosis volume is crucial in guiding treatment decisions and improving patient outcomes.

RNA polymerase II (RNAPII) is regulated by sequence-specific transcription factors (TFs) and the pre-initiation complex (PIC): TFIIA, TFIIB, TFIID, TFIIE, TFIIF, TFIIH, Mediator. TFs and Mediator contain intrinsically-disordered regions (IDRs) and form phase-separated condensates, but how IDRs control RNAPII function remains poorly understood. Using purified PIC factors, we developed a Real-time In-vitro Fluorescence Transcription assay (RIFT) for second-by-second visualization of RNAPII transcription at hundreds of promoters simultaneously.

Many species of mushroom-forming fungi have been harvested in the wild and used for food and medicine for thousands of years. In Brazil, the knowledge of the diversity of wild edible mushrooms remains scattered and poorly studied. Based on new samples, bibliographic records revision, and searches through the GenBank, we recorded 409 species of wild edible mushrooms in Brazil, of which 350 can be safely consumed and 59 are edible but with conditions.

Objectives: To prospectively validate the diagnostic performance of a non-invasive point-of-care tool (Rapid IAI System), including vaginal alpha-fetoprotein and interleukin-6, to predict the occurrence of intra-amniotic inflammation in a Spanish cohort of patients admitted with a diagnosis of preterm labor and intact membranes.

Methods: From 2017 to 2022, we prospectively evaluated a cohort of pregnant women diagnosed with preterm labor and intact membranes admitted below 34+0 weeks who underwent amniocentesis to rule-in/out intra-amniotic infection and/or inflammation. Vaginal sampling was performed at the time of amniocentesis or within 24-48 h.

Article Synopsis
  • Cardiac amyloidosis (CA) is an often overlooked cause of heart failure (HF), highlighting the importance of early detection and timely therapy for better patient outcomes.
  • A global survey with 1,460 physicians revealed that while many have experience diagnosing CA in patients with preserved ejection fraction (HFpEF), systematic screening is not widely practiced, with only 10% conducting routine checks.
  • There is significant variability in screening and management strategies for CA, indicating a need for better education and access to disease-modifying therapies within the HF community.

  • Respiratory syncytial virus (RSV) poses serious health risks for young children and elderly individuals, with current vaccines mainly available for adults over 60 and temporary protection for infants through maternal antibodies.
  • Researchers have developed a new type of vaccine that uses an anti-idiotypic monoclonal antibody (ai-mAb) specifically designed to target B cell receptors capable of producing RSV-neutralizing antibodies.
  • This novel approach effectively engages the right B cells without triggering unwanted immune responses, showcasing potential for a more effective infant vaccine against RSV.

Background: The increase in the use of induction of labor is a worldwide phenomenon in the current management of labor and delivery in Western societies, with approximately one out of every 4 pregnancies undergoing this procedure This has led women to seek various methods for stimulation of the onset of labor. Some data suggest that the use of acupuncture for favoring spontaneous labor onset could reduce the number of inductions of labor procedures. However, good quality evidence in this respect is not yet available.

The objectives of this study were to evaluate the ecophysiological state of the biota using a set of biomarkers in the upper-middle Luján River. To this aim, we collected adult Cnesterodon decemmaculatus fish, biofilm and water at three sampling sites in the upper-middle Luján River (S1: rural area, S2: Luján City and S3: urban area after passing Lujan City). For each site we determined physicochemical variables, heavy metal concentration in water, 19 biomarkers in fish (morphometric, histological, genotoxic, oxidative stress, metabolic and neurotoxic) and six biomarkers in biofilm (oxidative stress and extracellular enzyme).

Article Synopsis
  • A large-scale survey conducted in Latin America found that on average, 30.4% of managed honey bee colonies and 39.6% of stingless bee colonies were lost each year over a two-year period (2016-2018).
  • Summer losses for stingless bees (30.9%) were higher compared to winter losses (22.2%), while honey bee losses did not show the same seasonal pattern.
  • The survey revealed significant differences in colony loss rates between countries and over the years, indicating challenges in maintaining bee colony health and economic viability for those involved in beekeeping.

Background: Brain injury and poor neurodevelopment have been consistently reported in infants and adults born before term. These changes occur, at least in part, prenatally and are associated with intra-amniotic inflammation. The pattern of brain changes has been partially documented by magnetic resonance imaging but not by neurosonography along with amniotic fluid brain injury biomarkers.

Background: Preterm delivery is associated with cardiovascular remodeling and dysfunction in children and adults. However, it is unknown whether these effects are caused by the neonatal consequences of preterm birth or if these are already present in utero.

Objective: We evaluated fetal cardiac morphology and function in fetuses of mothers admitted for preterm labor or preterm prelabor rupture of membranes and the association of these changes with the presence of intra-amniotic infection and/or inflammation.

Pregnant women with absolute contraindications may be advised against physical activity throughout pregnancy. In this context, bed rest elevates the short-term risk of neonatal complications, thereby exacerbating negative long-term effects on childhood development. The aim of the current study was to investigate the impact of various physical activity interventions during bed rest or activity restriction in pregnancy on factors such as birth weight, preterm birth, maternal hypertension, gestational age at delivery, and the incidence of cesarean sections.

Background: Even though the use of nerve monitoring during parotid gland surgery is not the gold standard to prevent damage to the nerve, it surely offers some advantages over the traditional approach. Different from thyroid surgery, where a series of steps in intraoperative nerve monitoring have been described to confirm not only the integrity but-most importantly-the function of the recurrent laryngeal nerve, in parotid gland surgery, a formal guideline to follow while dissecting the facial nerve has yet to be described.

Methods: A five-year retrospective study was done reviewing the intraoperative records of patients who underwent parotid gland surgery under neural monitoring.

Gels combined with honey might generate new possibilities of textures in food development. This work explores the structural and functional properties of gelatin (5 g/100 g), pectin (1 g/100 g), and carrageenan (1 g/100 g) gels with different content of honey (0-50 g/100 g). Honey decreased the transparency of gels and made them more yellow-greenish; all of them were firm and uniform, especially at the highest honey content.
