Premise: The Flora e Funga do Brasil project is the most comprehensive effort to reliably document Brazilian plant and fungal diversity. It involves the collaborative work of hundreds of taxonomists, integrating detailed and standardized morphological descriptions, nomenclatural status, and geographic distribution information of plants, algae, and fungi collected throughout Brazil. Despite the extensive information available, managing the information from the Flora e Funga do Brasil website poses certain challenges.

Diversity of Acanthocephala parasites in Neotropical amphibians.

J Helminthol

January 2024

Laboratory of Biological Interactions, Federal University of Paraná, UFPR-Curitiba, Paraná, Brazil.

Acanthocephalans constitute a small taxonomic group related to rotifers and specialized in a parasitic lifestyle. Anurans act as paratenic and definitive hosts and infections always occur trophically. Our objective is to describe and summarize the richness of acanthocephalans in Neotropical anurans.

Background: PURA syndrome is a rare genetic disorder characterized by neonatal hypotonia, neurodevelopmental delay, facial dysmorphism, epileptic seizures, complex movement disorders, among other features. Although many pathogenic variants have been reported, there is currently no clear genotype-phenotype association identified.

Cases: Four patients diagnosed with PURA syndrome, despite carrying different pathogenic variants, presented a similar mixed hyperkinetic movement disorder.

Unlabelled: Type 1 diabetes mellitus (T1DM), associated with autoimmune destruction of pancreatic β cells, is observed in children and adolescents.

Objective: We investigated the potential association of the apolipoprotein M () polymorphisms rs707921, rs805264, rs805296, rs805297, and rs9404941 in childhood-onset T1DM ( = 144) and compared them to those in healthy (mostly Euro-Brazilian) children ( = 168).

Methods: This project was approved by the Ethics Committee of the Federal University of Parana (CAAE 24676613.

Anaplastic large cell lymphoma associated with breast implants is a relatively new disease that deserves attention from the academic community. Brazil figures as one of the protagonists in plastic surgery, however publications are insufficient and very few cases are reported in comparison to other countries. It is a disease with excellent prognosis when diagnosed early and treated effectively, but for this to happen, it is essential that health care professionals and the patient understand its pathology.

Biological contamination is one of the main bottlenecks in microalgae production, reducing quality and productivity and sometimes leading to the complete loss of the cultures. Selecting terpenes can be a pathway toward eco-friendly contamination control in microalgae cultures. This work evaluated the presence of bacterial contaminants in N.

Article Synopsis
  • The study aimed to assess how well the AH Plus sealer enters dentinal tubules after root canal retreatment using two different cleaning techniques.
  • Thirty-two mandibular premolars were divided into four groups for different retreatment methods, and the penetration of the sealer into dentinal tubules was analyzed using advanced microscopy.
  • Results showed that ProTaper Next retreatment led to better sealer penetration in the apical third of the root canal compared to Reciproc methods, while additional cleaning techniques did not enhance filling material removal across any evaluated sections.

Objective: There is no consensus in the literature regarding the relationship between high-resolution computed tomography findings and hearing thresholds in pure-tone audiometry in otosclerosis. This study evaluated the association between high-resolution computed tomography findings and pure-tone audiometry in otosclerosis in the spongiotic phase.

Methods: A cross-sectional study was conducted of 57 ears with surgically confirmed stapes fixation and tomographic findings.

Aim: One of the ways to avoid infection after surgical procedures is through antibiotic prophylaxis. This occurs in cholecystectomies with certain risk factors for infection. However, some guidelines suggest the use of antibiotic prophylaxis for all cholecystectomies, although current evidence does not indicate any advantage of this practice in the absence of risk factors.

Macrocyclic lactone resistance in nematodes of cattle in Brazil: Blame it to the ticks!

Parasitol Int

August 2022

Laboratory of Veterinary Clinical Parasitology, Federal University of Parana. Curitiba, PR, Brazil; Graduate Program of Microbiology, Parasitology and Pathology, Federal University of Parana, UFPR, Curitiba, PR, Brazil.

Article Synopsis
  • Strategic control of helminths (parasites) in adult cattle is not enough to significantly affect parasite populations, but resistance to macrocyclic lactone (ML) treatments has been documented globally, prompting an evaluation of studies from 2001 to 2020 in Brazil.
  • Out of 246 reports reviewed, 19 of 21 studies showed resistance in various helminth species, but a lack of data on treatment frequency was noted; a farmer survey indicated over 70% rotate products and commonly treat animals monthly or biweekly.
  • High exposure to ML, averaging up to 16 times a year, alongside frequent use of acaricides for tick and horn-fly control, suggests that helmin

The present study aimed to evaluate the effect of parathormone (PTH) administered directly to the implant's surface prior to insertion, using a large translational animal model. Sixty titanium implants were divided into four groups: (i) Collagen, control group, where implants were coated with Type-I Bovine-collagen, and three experimental groups, where implants received varying doses of PTH: (ii) 12.5, (iii) 25, and (iv) 50 μg, prior to placement.

Background: Cervical dystonia (CD) involves clinical and motor manifestations, and visual and cognitive dysfunctions may also be frequent.

Objective: To evaluate functional vision, visual attention, and cognitive aspects in patients with CD compared with a control group.

Methods: Fifty patients with CD were assessed using the Useful Field of View Test (UFOV), the Mini Mental State Examination (MMSE), and the Trail Making Tests (TMT-A and TMT-B), and compared with an identical number of health controls matched by sex, age, and educational level.

Article Synopsis
  • Determining herbage intake is essential for understanding grazing ecology, and this study compares the Continuous Bite Monitoring (CBM) method to the traditional double-weighing technique for measuring herbage intake in grazing sheep.
  • The study involved various experiments that assessed factors affecting the reliability of CBM, such as observer count, forage species, and sward height, finding significant variations impacting intake estimations.
  • Results showed a strong correlation between the two methods, but CBM tended to overestimate intake in certain experiments, highlighting its potential for detailed insights into foraging behavior while remaining non-invasive to animal activity.

Principles of pharmacoeconomic analysis: the case of pharmacist-led interventions.

Pharm Pract (Granada)

February 2021

Center for Health Technology and Services Research (CINTESIS), Laboratory of Pharmacology, Faculty of Pharmacy, University of Porto . Porto ( Portugal ).

In the past years, several factors such as evidence-based healthcare culture, quality-linked incentives, and patient-centered actions, associated with an important increase of financial constraints and pressures on healthcare budgets, resulted in a growing interest by policy-makers in enlarging pharmacists' roles in care. Numerous studies have demonstrated positive therapeutic outcomes associated with pharmaceutical services in a wide array of diseases. Yet, the evidence of the economic impact of the pharmacist in decreasing total health expenditures, unnecessary care, and societal costs relies on well-performed, reliable, and transparent economic evaluations, which are scarce.

Down syndrome is the most common chromosomal disorder, affecting 1/700 live births. Among the clinical findings, one constant concern is the high prevalence of visual disorders that, if left untreated, can negatively affect child development. The aim of this study was to determine the prevalence of ophthalmological findings among patients who attended an outpatient clinic for patients with Down syndrome in southern Brazil between 2005 and 2016.

Peer review provides the foundation for the scholarly publishing system. The conventional peer review system consists of using authors of articles as reviewers for other colleagues' manuscripts in a collaborative-basis system. However, authors complain about a theoretical overwhelming number of invitations to peer review.
