Background: Inherited retinal dystrophies (IRD) are one of the main causes of incurable blindness worldwide. IRD are caused by mutations in genes that encode essential proteins for the retina, leading to photoreceptor degeneration and loss of visual function. IRD generates an enormous global financial burden due to the lack of understanding of a significant part of its pathophysiology, molecular diagnosis, and the near absence of non-palliative treatment options.

Article Synopsis
  • A study in Cameroon investigated trypanosome infections in 291 domestic and wild animals to update existing epidemiological data on human African trypanosomiasis (HAT).
  • Researchers found that 47.1% of animals had at least one trypanosome species, with significant infections in both blood (65.7%) and skin (23.4%).
  • The findings underline the importance of animal reservoirs, especially pigs and wild animals, in the transmission of Trypanosoma b. gambiense, suggesting that these factors should be integrated into HAT control strategies.

Age-related macular degeneration (AMD) is a complex, multifactorial, progressive retinal disease that affects millions of people worldwide and has become the leading cause of visual impairment in developed countries. The disease etiopathogenesis is not understood fully, although many triggers and processes that lead to dysfunction and degeneration of the retinal pigment epithelium (RPE) have already been identified. Thus, the lack of cellular control of oxidative stress, altered proteostasis, dysfunction of lipid homeostasis, and mitochondrial dysfunction form an internal feedback loop that causes the RPE to fail and allows accumulation of abnormal misfolded proteins and abnormal lipids that will form drusen.

Childhood acute lymphoblastic leukemia (ALL), the most common pediatric cancer, is a heterogeneous disease comprised of multiple molecular subtypes with distinct somatic genetic alterations, which results in different outcomes for the patients. Accurate patient risk stratification through genetic markers could increase survival rates, but the identification of reliable biomarkers is needed, as 20‑30% of B‑ALL patients cannot be classified in the clinic with routine techniques and some patients classified as low‑risk and good‑responders to treatment will eventually relapse. Long non‑coding RNAs (lncRNAs) can represent novel candidates with diagnostic, classification, prognosis, and treatment response potential.

Current avian migration patterns in temperate regions have been developed during the glacial retreat and subsequent colonization of the ice-free areas during the Holocene. This process resulted in a geographic gradient of greater seasonality as latitude increased that favoured migration-related morphological and physiological (co)adaptations. Most evidence of avian morphological adaptations to migration comes from the analysis of variation in the length and shape of the wings, but the existence of intra-feather structural adjustments has been greatly overlooked despite their potential to be under natural selection.

Presenilin 1 (PSEN1) is a γ-secretase component, which is in charge of the amyloid precursor protein (APP) cleavage. APP is believed to play a central role in the pathogenesis of Alzheimer's disease (AD). PSEN1 mutations are the most important causes of familial AD, being related to the earlier onset and rapid progression of the disease.

High-risk hematological malignancies are a privileged setting for infection by opportunistic microbes, with invasive mycosis being one of the most serious complications. Recently, genetic background has emerged as an unanticipated risk factor. For this reason, polymorphisms for genes encoding archetypal receptors involved in the opsonic and nonopsonic clearance of microbes, pentraxin-3 (PTX3) and Dectin-1, respectively, were studied and correlated with the risk of infection.

Background: The optimal treatment of acute Achilles tendon ruptures remains controversial. When surgical repair is undertaken, the reported rate of infections and wound-healing complications ranges from 2% to 5%. Meta-analyses have demonstrated that minimally invasive approaches have equivalent rerupture rates, a significantly lower risk of superficial infections, and higher patient satisfaction rates compared with traditional open Achilles repair techniques.

This is the first study to explore the potential of various geometric morphometrics methods to help the morphological diagnostic of tsetse species, vectors of human and animal trypanosomiases in sub-Saharan Africa. We compared landmarks, semilandmarks and outlines techniques on male and female samples of species, and suggested adapted strategies according to the countries and their own Glossina fauna. We could compare up to 7 taxa belonging to the three main subgenera of the Glossina genus: Nemorhina (5 species), Glossina (1 species) and Austenina (1 species).

Background: Reported complications of pediatric septic arthritis range from minor growth abnormalities to potentially life-threatening conditions and death; some children require multiple surgeries for eradication of infection. The purpose of this study is: (1) to determine the failure rate of a single surgical incision and drainage (I&D) in pediatric septic arthritis, (2) to identify risk factors for failure which are detectable at the time of initial presentation, and (3) to trend post-operative C-reactive protein (CRP) values to see if there is a difference between children who fail a single I&D and those who do not.

Methods: The medical records for 105 children who underwent operative management of septic arthritis were retrospectively reviewed.

We studied the effect of climate change on the distribution of two insectivorous passerines (the meadow pipit Anthus pratensis and the chiffchaff Phylloscopus collybita) in wintering grounds of the Western Mediterranean basin. In this region, precipitation and temperature can affect the distribution of these birds through direct (thermoregulation costs) or indirect effects (primary productivity). Thus, it can be postulated that projected climate changes in the region will affect the extent and suitability of their wintering grounds.

We have analyzed the comportment in in vitro culture of 2 different genotypes of Trypanosoma cruzi, the agent of Chagas disease, pertaining to 2 major genetic subdivisions (near-clades) of this parasite. One of the stocks was a fast-growing one, highly virulent in mice, while the other one was slow-growing, mildly virulent in mice. The working hypothesis was that mixtures of genotypes interact, a pattern that has been observed by us in empirical experimental studies.
