Article Synopsis
  • The Gran Chaco ecoregion in Argentina is a hotspot for neglected tropical diseases like Chagas and soil-transmitted helminthiasis, prompting a study on how co-infections affect infection outcomes.
  • Researchers conducted a survey testing for T. cruzi and intestinal parasites in two rural villages, measuring parasite load and host infectiousness.
  • Findings showed a significant prevalence of co-infection, with helminth co-infections greatly increasing the likelihood of higher T. cruzi infection and increased infectiousness to vectors, suggesting immune interactions between these parasites.

Background: Studies comparing the frequency of different mental health conditions across different settings and evaluating their association with parental participation in newborn care are lacking. We aimed at evaluating the frequency of parental stress, anxiety and depression, along with the level of participation in newborn care, among parents of newborns in Italy, Brazil and Tanzania.

Methods: Parental stress, anxiety, depression and participation in care were assessed prospectively in parents of newborns in eight neonatal intensive care units (NICUs) utilising: the Parental Stressor Scale in NICU (PSS:NICU); the Edinburgh Postnatal Depression Scale (EPDS) and EPDS-Anxiety subscale (EPDS-A); the Index of Parental Participation in NICU (IPP-NICU).

Breastfeeding is a fundamental biological function in mammals, allowing the progeny to develop in a physiological way. A physical and emotional dialog between mothers and offspring during breastfeeding has been described as part of the attachment relationship, and a synchronicity between maternal and neonatal brains can be hypothesized. This study aimed to assess if neonatal and maternal cortical areas activated during breastfeeding are functionally synchronized since the second day of life.

Article Synopsis
  • The study aimed to create percentile charts for arterial oxygen saturation (SpO), heart rate (HR), and cerebral oxygen saturation (crSO) in very or extremely preterm neonates during their first 15 minutes after birth.
  • It analyzed data from the COSGOD III trial, focusing on neonates with favorable outcomes, excluding those with early inflammatory issues, and utilized various methods for measuring the oxygen and heart metrics.
  • The findings revealed specific percentiles for SpO, HR, and crSO at 2, 5, 10, and 15 minutes post-birth, providing a new reference that could aid in better managing oxygen levels during the critical stabilization period after delivery.

Unlabelled: Changes in the organization of the clinical care wards, requested by the SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) pandemic, have influenced the environmental circulation of other pathogens. The implementation of prevention procedures may have led to a decrease in the incidence of healthcare-associated infections. We aimed to investigate the impact of prevention and control measures for preventing the COVID-19 spread on the incidence of bacterial sepsis and invasive fungal infections in neonates and infants requiring major surgery.

Cyclophilins (CyPs) are a family of enzymes involved in protein folding. , the causative agent of Chagas disease, has a 19-kDa cyclophilin, CyP19, that was found to be secreted in parasite stages of the CL Brener clone and recognized by sera from -infected mice and patients. The levels of specific antibodies against CyP19 in -infected mice and subjects before and after drug treatment were measured by an in-house enzyme linked immunosorbent assay (ELISA).

The effectiveness of "inadequate" intrapartum antibiotic prophylaxis (IAP administered < 4 h prior to delivery) in preventing early-onset sepsis (EOS) is debated. Italian prospective surveillance cohort data (2003-2022) were used to study the type and duration of IAP according to the timing of symptoms onset of group B streptococcus (GBS) and culture-confirmed EOS cases. IAP was defined "active" when the pathogen yielded in cultures was susceptible.

Background: Extrauterine growth restriction (EUGR) is common among very low birth weight (VLBW) infants and associated with poor neurodevelopmental outcomes. There are two types of EUGR definitions (cross-sectional and longitudinal) and many growth charts for monitoring postnatal growth. Aims of our study were 1) to compare the rate of small for gestational rate (SGA) and EUGR in a population of VLBW infants, both according to different growth charts (Fenton, INeS charts and Intergrowth-21) and different definitions; 2) to identify risk factors for EUGR.

Benznidazole and nifurtimox are the drugs currently used for the treatment of Chagas disease, however its side effects may affect patient adherence. In the search for new alternative therapies, we previously identified isotretinoin (ISO), an FDA-approved drug widely used for the treatment of severe acne through a drug repurposing strategy. ISO shows a strong activity against Trypanosoma cruzi parasites in the nanomolar range, and its mechanism of action is through the inhibition of T.

Background: The distribution of parasite load across hosts may modify the transmission dynamics of infectious diseases. Chagas disease is caused by a multi-host protozoan, Trypanosoma cruzi, but the association between host parasitemia and infectiousness to the vector has not been studied in sylvatic mammalian hosts. We quantified T.

Recent studies reported, during the COVID-19 pandemic, increased mental distress among the general population and among women around the childbirth period. COVID-19 pandemic may undermine the vulnerable well-being of parents in Neonatal Intensive Care Units (NICUs). Our study aimed to explore whether parental stress, depression, and participation in care in an Italian NICU changed significantly over three periods: pre-pandemic (T), low (T), and high COVID-19 incidence (T).

Group B streptococcus (GBS) infection remains a leading cause of sepsis, pneumonia, and meningitis in infants. Rates of GBS early onset disease have declined following the widcespread use of intrapartum antibiotic prophylaxis; hence, late-onset infections (LOGBS) are currently a common presentation of neonatal GBS dicsease. The pathogenesis, mode of transmission, and risk factors associated with LOGBS are unclear, which interfere with effective prevention efforts.

Background: Current algorithm for Congenital Chagas Disease (cCD) diagnosis is unsatisfactory due to low sensitivity of the parasitological methods. Moreover, loss to follow-up precludes final serodiagnosis after nine months of life in many cases. A duplex TaqMan qPCR kit for Trypanosoma cruzi DNA amplification was prospectively evaluated in umbilical cord (UCB) and peripheral venous blood (PVB) of infants born to CD mothers at endemic and non-endemic sites of Argentina.

Infections represent a serious health problem in neonates. Invasive infections (ICIs) are still a leading cause of mortality and morbidity in neonatal intensive care units (NICUs). Infants hospitalized in NICUs are at high risk of ICIs, because of several risk factors: broad spectrum antibiotic treatments, central catheters and other invasive devices, fungal colonization, and impaired immune responses.

Background: Interruption of benznidazole therapy due to the appearance of adverse effects, which is presumed to lead to treatment failure, is a major drawback in the treatment of chronic Chagas disease.

Methods: Trypanosoma cruzi-specific humoral and T cell responses, T cell phenotype and parasite load were measured to compare the outcome in 33 subjects with chronic Chagas disease treated with an incomplete benznidazole regimen and 58 subjects treated with the complete regimen, during a median follow-up period of 48 months.

Results: Both treatment regimens induced a reduction in the T.
