Postural Abnormalities in Children with Congenital Zika Syndrome-Related Neurological and Visual Impairment.

Deformities, body asymmetries, and muscle contractures are common consequences of atypical postural patterns in children with c ongenital Zika syndrome (CZS). This study aimed to evaluate the posture of children with CZS, considering their neurological and visual impairments. Ophthalmological assessment included binocular best-corrected visual acuity (BCVA) using Teller Acuity Cards II (TAC II) and an ocular motility evaluation.

Assessment of Affordances in the Home Environment and Neurodevelopment of Children With Congenital Zika Syndrome.

Background: Congenital Zika syndrome (CZS) is characterized by brain abnormalities caused by in utero exposure to the Zika virus (ZIKV), resulting in significant neurodevelopmental, motor and visual impairments in affected children. These impairments hinder their ability to engage in social interactions and explore their surroundings. However, personalized and continuous sensory stimulation, particularly within the home environment, may play a crucial role in supporting motor and visual development in these children.

Long-term visual and neurodevelopmental outcomes in children with Congenital Zika Syndrome after undergoing strabismus surgery.

: To assess long-term visual and neurodevelopmental outcomes in children with congenital Zika syndrome (CZS) after strabismus surgery. : A consecutive sample of five children with CZS who underwent strabismus surgery was enrolled. All children underwent a standardized pre- and postoperative protocol including binocular best-corrected visual acuity (BCVA) using the Teller Acuity Cards II (TAC II), ocular alignment, functional vision using the functional vision developmental milestones test (FVDMT), and neurodevelopmental milestone evaluation using the Bayley Scales of Infant Development-Third Edition (BSID-III).

This study was carried out to identify the spatial distribution and characterize the clinical-epidemiological profile of Visceral Leishmaniasis (VL) in Maranhão state, Brazil, from 2009 to 2020. This descriptive ecological study collected sociodemographic and clinical data of VL cases from the Brazilian Notifiable Diseases Information System database. A spatial autocorrelation analysis (Moran statistics) was performed.

In vitro inhibition and eradication of multidrug-resistant Acinetobacter baumannii biofilms by riparin III and colistin combination.

Acinetobacter baumannii, a prominent emerging pathogen, is responsible for persistent and recurrent healthcare-associated infections (HAIs). Its bacterial resistance and virulence factors, such as biofilm formation, contribute to its survival in hospital environments. Combination therapy has proven to be an effective approach for controlling these infections; however, antimicrobial resistance and compound toxicity can hinder antimicrobial efficacy.

Benzonidazole treatment has a beneficial effect on cells infected with the Colombian strain of Trypanosoma cruzi.

Benznidazole (Bz) is the recommended drug for the treatment of Chagas disease; however, its efficacy may vary according to the sensitivity of Trypanosoma cruzi strains to the drug and host immune background. The study evaluated the immune response of peripheral blood mononuclear cells (PBMC) that were infected in vitro with the Colombian strain (Col) and treated with Bz. The co-cultures were incubated for 24 h, 5 and 10 days, where cytokine dosage was performed in the supernatant and evaluation of the cells for CD28 and CTLA-4 molecules in CD4 and CD8 lymphocytes, and CD80 , CD86 and HLA-DR in CD14 cells.

Telangiectatic Capillaries in Retinal Vascular Occlusions: Multimodal Imaging in a Case Series.

To report a cases series of retinal vascular occlusions with telangiectatic capillaries (TelCaps) seen on indocyanine green angiography (ICGA) and multimodal imaging. In this case series, a new finding (TelCaps) was seen on clinical examination, fundus evaluation, fluorescein angiography, ICGA, and optical coherence tomography (OCT). This series comprised 3 patients with TelCaps findings on ICGA after retinal vascular occlusions.

Central retinal artery occlusion with cilioretinal artery sparing secondary to COVID-19: Additional ocular complication.

We describe a 68-year-old female patient with unilateral central retinal artery occlusion (CRAO) with cilioretinal artery sparing post-coronavirus disease 2019 (COVID-19) infection. The patient presented with acute vision loss in the left eye 11 days after discharge from a severe COVID-19 infection, with altered D-dimer, C-reactive protein, and fibrinogen levels. The best-corrected visual acuity (BCVA) in the left eye was 20/400; fundoscopic examination revealed diffuse pallor retina with a patent arterial branch from the optic disk to the fovea, confirmed by fluorescein angiography.

We report the case of a 2-year-old girl with acute-onset divergent strabismus and ptosis in the right eye. She had an exotropia of 45 for near, eyelid ptosis affecting the visual axis, adduction, limitations of up- and downgaze, and a discrete mydriasis in the right eye. Neurological conditions were ruled out.

Benznidazole: Hero or villain of cellular immune response in chronic Chagas disease patients?

Although the treatment of chronic Chagas disease (CCD) patients with Benznidazole (Bz) is still controversial, its use may prevent or delay the progression of the disease to the most severe forms. One of the main factors that can influence the effectiveness of the treatment is the possible cooperation between drug effect and the host immune response. Herein, we evaluated the immune response of peripheral blood mononuclear cells (PBMCs) infected with Trypanosoma cruzi and submitted to Bz treatment.

Asteraceae Plants as Sources of Compounds Against Leishmaniasis and Chagas Disease.

Leishmaniasis and Chagas disease cause great impact on social and economic aspects of people living in developing countries. The treatments for these diseases are based on the same regimen for over 40 years, thus, there is an urgent need for the development of new drugs. In this scenario, Asteraceae plants (a family widely used in folk medicine worldwide) are emerging as an interesting source for new trypanocidal and leishmanicidal compounds.

A trypsin inhibitor from Moringa oleifera flower extract is cytotoxic to Trypanosoma cruzi with high selectivity over mammalian cells.

In this study, Moringa oleifera flower extract and a trypsin inhibitor (MoFTI) isolated from it were evaluated for anti-protozoal activity against Trypanosoma cruzi and cytotoxicity to mammalian cells. The presence of flavonoids was remarkable in the HPLC fingerprints of the extract at 254 and 360 nm. Amino acid sequences of peptides derived from in-gel digestion of MoFTI were determined.

pCramoll and rCramoll as New Preventive Agents against the Oxidative Dysfunction Induced by Hydrogen Peroxide.

Oxidative stress plays an important role in the induction of cell death and is associated with various pathologic disorders; therefore, the search for natural products that attenuate the effects produced by oxidant agents is greatly increased. Here, the protective effects of native lectin from Cratylia mollis seeds (pCramoll) and recombinant Cramoll 1 (rCramoll) against H2O2-induced oxidative stress in Vero cells were evaluated. Both lectins significantly attenuated the H2O2-induced cytotoxicity in a concentration-dependent way.

The extract showed significant inhibitory effect on the growth of promastigote forms (IC50=71.

Trypanocidal and cytotoxic activities of essential oils from medicinal plants of Northeast of Brazil.

Chagas disease, caused by Trypanosoma cruzi, is an important cause of mortality and morbidity in Latin America. There are no vaccines available, the chemotherapy used to treat this illness has serious side effects and its efficacy on the chronic phase of disease is still a matter of debate. In a search for alternative treatment for Chagas disease, essential oils extracted from traditional medicinal plants Lippia sidoides, Lippia origanoides, Chenopodium ambrosioides, Ocimum gratissimum, Justicia pectorales and Vitex agnus-castus were investigated in vitro for trypanocidal and cytotoxic activities.
