Unveiling mycobacterial infections in Brazilian swine: Insights from epidemiological and diagnostic studies.

Stringent sanitary standards are imperative for swine production, ensuring high biosecurity and safe meat. However, granulomatous lesions, often detected as "lymphadenitis" in slaughterhouses, lack routine laboratory examination, potentially overlooking tuberculosis among other etiologies. This study aimed to: (i) explore epidemiological variables linked to swine carcasses condemned due to "tuberculosis" or "lymphadenitis" in Rio Grande do Sul, southern Brazil in a retrospective survey; and (ii) evaluate the frequency of Mycobacterium tuberculosis in granulomatous lymphadenitis lesions.

Raman-Enabled Predictions of Protein Content and Metabolites in Biopharmaceutical Fermentations.

Raman spectroscopy, a robust and non-invasive analytical method, has demonstrated significant potential for monitoring biopharmaceutical production processes. Its ability to provide detailed information about molecular vibrations makes it ideal for the detection and quantification of therapeutic proteins and critical control parameters in complex biopharmaceutical mixtures. However, its application in fermentations has been hindered by the inherent strong fluorescence background from the cells.

Contrasting Approaches in the Implementation of GRADE Methodology in Guidelines for Haemophilia and Von Willebrand Disease.

Aim: Discuss missed opportunities and the methodological approach of the ISTH Guideline in contrast to how GRADE was previously applied in rare diseases.

Methods: Critically analyse the methodology of each guideline along with best practices in the use of GRADE.

International Society on Thrombosis and Haemostasis Clinical Practice Guideline for Treatment of Congenital Haemophilia-A Critical Appraisal.

Introduction: Evidence-based clinical practice guidelines drive optimal patient care and facilitate access to high-quality treatment. Creating guidelines for rare diseases such as haemophilia, where evidence does not often come from randomized controlled trials but from non-randomized and well-designed observational studies and real-world data, is challenging. The methodology used for assessing available evidence should consider this critical fact.

Simplifying Management of Cholestasis: A Proposal for a Classification System.

Given the stillbirth risk associated with intrahepatic cholestasis of pregnancy, management to reduce this adverse outcome has primarily involved planned delivery as early as 36 weeks gestation. While earlier planned delivery has decreased the incidence of stillbirth in this population, recently, there have been multiple published retrospective studies to better correlate the association of adverse outcomes with cholestasis severity. Despite these new data, the uptake of individualized management for cholestasis has been varied from provider to provider.

Cytotoxic and Antibacterial Activity of Koninginins Isolated from the Mangrove-Derived Endophytic Fungus sp.

The search for bioactive compounds for the treatment of several diseases has led to the study of endophytic fungi. Neoplastic diseases are among the most significant health concerns due to their high mortality rate, and there is a dearth of efficacious pharmaceutical agents for the treatment of cancer. Gastric cancer is one of the most aggressive forms of cancer and is among those with the highest mortality rates in Brazil.

Imaging Assessment of Prostate Cancer Extra-prostatic Extension: From Histology to Controversies.

Prostate cancer (PCa) is the most common non-skin malignancy among men and the fourth leading cause of cancer-related deaths globally. Accurate staging of PCa, particularly the assessment of extra-prostatic extension (EPE), is critical for prognosis and treatment planning. EPE, typically evaluated using magnetic resonance imaging (MRI), is associated with higher risks of positive surgical margins, biochemical recurrence, metastasis, and reduced overall survival.

Unveiling the unknown diversity of planktonic green algae (Chlorophyta) in urban ponds in the semiarid region of Northeastern Brazil.

This study examined the taxonomic composition and ecological aspects of planktonic green algae (Chlorophyta) in four urban ponds (Parque da Lagoa, Lagoa Grande, Laguneville, and Pindoba) in Feira de Santana, Bahia State, Brazil. We analyzed 96 samples collected bimonthly in 2022 and identified 54 taxa, with the majority (42) classified as uncommon or sporadic. The most common species were Monoraphidium circinale and Lemmermannia komarekii, found in 100% and 95.

The effects of simultaneous point gains and losses on human persistence.

Four experiments assessed the effects of simultaneous point gains and losses on human responding on a moving response button. Experiments 1 and 2 examined the effects of point loss arranged in variable-time (VT) and variable-interval (VI) schedules on persistence. For that purpose, a multiple schedule was in force.

A quasi-experimental study assessing the effectiveness of a community-based egg intervention in the nutritional and health status of young children from rural Honduras.

Design: This investigator-blind, non-randomized, controlled study was informed by a community health improvement process and participatory research. Women from 13 communities were given a microloan to start an egg farm that supplied 1 egg daily to 201 children ages 6-24 months for 1 year (intervention group).

Gallbladder Burkitt's Lymphoma: A Literature Review Including a Case Report in a Child Living with HIV.

Malignant lymphoma is an unusual form of gallbladder neoplasm. Almost all these tumors are diffuse large B-cell lymphomas or mucosa-associated lymphoid tissue-type lymphomas. Herein, we present a literature review of gallbladder Burkitt's lymphoma (BL) cases that includes also an unpublished case in an HIV-infected child, observed by our center.

State of the Science: Using Digital Mental Health Interventions to Extend the Impact of Psychological Services.

In recent years, digital mental health interventions (DMHIs) have emerged as a paradigm shift in care delivery that could expand the scale, efficiency, and effectiveness of psychological services. However, DMHI impact is constrained by issues related to limited reach, poor adoption, implementation barriers, and insufficient long-term maintenance. Organized by the Reach, Effectiveness, Adoption, Implementation, and Maintenance(RE-AIM) framework, this paper surveys the current state of DMHIs, highlighting research and practice gaps as well as potential strategies to move the field forward.

Do Temperature Abuses Along the Frozen Açaí Pulp Value Chain Increase Microbial Hazards?

Does temperature abuse during storage, distribution, marketing, and consumption of unpasteurized frozen açaí pulp increase microbial hazards? This study investigated the behavior of potentially pathogenic ( spp.) and spoilage (mesophilic bacteria, yeasts and molds) microorganisms in two simulated thawing conditions: under refrigeration and at room temperature. The effect of repeated cold chain abuse was observed by thawing and refreezing (-20°C) açaí pulp four times over a period of 90 days.

Inflammatory and adhesion profile of gingival fibroblasts to lithium disilicate ceramic surfaces.

Objectives: Lithium disilicate (LS) ceramic emerges as a compelling option for customized implant abutments. However, ensuring its safety and reliability requires clarification on key aspects, notably its impact on inflammation and potential for cell adhesion. This study delves into these considerations, examining the influence of LS ceramic on cytokine release and the transcriptional profile of human gingival fibroblasts (hGFs) in direct contact with various LS surfaces.

Direct monitoring of the enzymatically sequestering and degrading of PET microplastics using hyperspectral Raman microscopy.

Microplastics are commonly referred to as tiny plastic fragments polluting our environment, although their nanometric forms have also been found in our drinking water supplies and many living systems. Their removal is relevant for preserving our health and sustainability and is being pursued according to many different strategies, including filtration through selective porous materials or agglomeration using flocculant agents. An alternative nanotechnological approach described in this paper deals with the capture and degradation of micro and nanoplastics by enzyme-immobilized magnetic nanoparticles.

Interaction between gas channels in water-saturated sands.

This work investigates the interaction between gas channels in a vertical Hele-Shaw cell when air is injected simultaneously from two points at a constant flow rate. Unlike single-injection experiments, this dual-point system induces the formation of numerous bubbles, thereby intensifying the interactions between air channels. We use an image analysis technique for tracking motion in the granular bed to define a flow density parameter throughout the cell.

Trajectories of Change in Parent-Child Interaction Therapy Outcomes in Latinx Families: Implications for Cultural Adaptation.

Objective: Parent-Child Interaction Therapy (PCIT) is a parenting program in which caregivers must achieve "skill criteria" in using and avoiding to complete treatment. Despite PCIT's emphasis on these skills, little is known about how Latinx caregivers acquire these Western-based parenting practices and whether cultural mismatches lead to inequities in outcomes. This study compared the trajectories of change in PCIT skills and treatment outcomes of Latinx and non-Latinx White families.
