Peptide PaDBS1R6 has potent antibacterial activity on clinical bacterial isolates and integrates an immunomodulatory peptide fragment within its sequence.

BACKGROUND: Resistant infectious diseases caused by gram-negative bacteria are among the most serious worldwide health problems. Antimicrobial peptides (AMPs) have been explored as promising antibacterial, antibiofilm, and anti-infective candidates to address these health challenges. MAJOR CONCLUSIONS: Here we report the potent antibacterial effect of the peptide PaDBS1R6 on clinical bacterial isolates and identify an immunomodulatory peptide fragment incorporated within it. PaDBS1R6 was evaluated against Acinetobacter baumannii and Escherichia coli clinical isolates and had minimal inhibitory concentration (MIC) values from 8 to 32 µmol L-1. It had a rapid bactericidal effect, with eradication showing within 3 min of incubation, depending on the bacterial strain tested. In addition, PaDBS1R6 inhibited biofilm formation for A. baumannii and E. coli and was non-toxic toward healthy mammalian cells. These findings are explained by the preference of PaDBS1R6 for anionic membranes over neutral membranes, as assessed by surface plasmon resonance assays and molecular dynamics simulations. Considering its potent antibacterial activity, PaDBS1R6 was used as a template for sliding-window fragmentation studies (window size = 10 residues). Among the sliding-window fragments, PaDBS1R6F8, PaDBS1R6F9, and PaDBS1R6F10 were ineffective against any of the bacterial strains tested. Additional biological assays were conducted, including nitric oxide (NO) modulation and wound scratch assays, and the R6F8 peptide fragment was found to be active in modulating NO levels, as well as having strong wound healing properties. GENERAL SIGNIFICANCE: This study proposes a new concept whereby peptides with different biological properties can be derived by the screening of fragments from within potent AMPs.

Applicability of mouse models for induction of severe acute lung injury.

Acute lung injury (ALI) is a significant clinical challenge associated with high morbidity and mortality. Worldwide, it affects approximately 200.000 individuals annually, with a staggering 40 % mortality rate in hospitalized cases and persistent complications in out-of-hospital cases. This review focuses on the key immunological pathways underlying bacterial ALI and the exploration of mouse models as tools for its induction. These models serve as indispensable platforms for unraveling the inflammatory cascades and biological responses inherent to ALI, while also facilitating the evaluation of novel therapeutic agents. However, their utility is not without challenges, mainly due to the stringent biosafety protocols required by the diverse bacterial virulence profiles. Simple and reproducible models of pulmonary bacterial infection are currently available, including intratracheal, intranasal, pleural and, intraperitoneal approaches. These models use endotoxins such as commercially available lipopolysaccharide (LPS) or live pathogens such as Pseudomonas aeruginosa, Mycobacterium tuberculosis, and Streptococcus pneumoniae, all of which are implicated in the pathogenesis of ALI. Combining murine models of bacterial lung infection with in-depth studies of the underlying immunological mechanisms is a cornerstone in advancing the therapeutic landscape for acute bacterial lung injury.

Synovial fluid NMR-based metabolomics in septic and aseptic revision total knee arthroplasty: Implications on diagnosis and treatment.

Periprosthetic joint infection (PJI) is one of the most challenging complications following total knee arthroplasty. Despite its importance, there is a paucity of reports in the literature regarding its pathogenesis. Recently, cellular metabolic reprogramming has been shown to play an important role in the progression and outcome of infectious diseases. Therefore, the aim of this study was to evaluate the metabolites composition of the synovial fluid from patients with PJI or aseptic failure of total knee arthroplasties. The synovial fluids from 21 patients scheduled for revision total knee arthroplasty (11 with the diagnosis of PJI and 10 with aseptic failures) were analyzed using 1D 1H NMR spectroscopy. Univariate and multivariate statistical analyzes were used to identify metabolites that were differentially abundant between those groups. A total of 28 metabolites were identified and five of them found to be differentially abundant between infected and non-infected synovial fluids. Lactate, acetate and 3-hydroxybutyrate were found to be in a higher concentration, and glucose and creatine were found reduced in the synovial fluid from PJI patients. Synovial fluid from patients with PJI exhibit a distinct metabolic profile, possibly reflecting metabolic adaptation that occurs in the infected periprosthetic microenvironment. Further research and studies are warranted to gain a broader insight into the metabolic pathways engaged by both pathogen and immune cells in the context of a PJI.

Effectiveness of Photobiomodulation in Reducing Pain and Disability in Patients with Knee Osteoarthritis: A Systematic Review with Meta-Analysis.

OBJECTIVE: Photobiomodulation (PBM) is not implemented in routine clinical management for knee osteoarthritis. This study aims to systematically investigate the effects of PBM in patients with knee osteoarthritis, comparing to placebo to understand its true clinical effects. METHODS: PubMed, EMBASE, Web of Science, and Cochrane databases were searched up to October 2023. Randomized placebo-controlled trials applying PBM versus placebo were included. Study characteristics, intervention parameters, and patient-reported and physical examination outcome measures were collected. The risk of bias was judged using the Cochrane risk-of-bias tool for randomized trials (version 2) and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) to interpret certainty of results. RESULTS: Ten studies were included comprising 542 participants. All studies were judged with unclear to high risk of bias. Meta-analysis for pain at rest (6 studies) showed that PBM significantly reduced pain at rest as compared to placebo (-0.7 [95% CI = -1.1 to -0.2]), moderate effect, very low certainty of evidence, whereas for the Timed "Up & Go" Test (3 studies), no significant effect was detected. Statistically significantly within-group (PBM) mean improvement was detected for pain, Lequesne Index, and gait performance outcomes, but not always clinically relevant or significant when compared to placebo. CONCLUSION: PBM reduces pain intensity in patients with knee osteoarthritis and may improve disability. However, the very low certainty of evidence does not allow to recommend its isolated use but may be used to complement other widely recommended therapies. More rigorous clinical trials and the revision of the recommended dosage guidelines are warranted to increase the strength of evidence. IMPACT: The findings indicate that photobiomodulation can reduce pain and improve disability in patients with knee osteoarthritis. However, researchers should continue to investigate isolated photobiomodulation intervention versus placebo and extend the dosage guidelines to other types of light emitters.

Neutralizing antibody responses to the Delta variant of SARS-CoV-2 following vaccination with Ad5-nCoV (CanSino) in the Mexican population.

During the COVID-19 pandemic, the Ad5-nCoV vaccine was applied to the Mexican population before the WHO approved it. In a transversal study, we compare the CanSino vaccine efficacy and a natural SARS-CoV-2 infection in eliciting neutralizing antibodies against the SARS-CoV-2 Delta variant in Guadalajara, Mexico. Participants between 30-60 years were included in the study and classified into three groups: 1) Natural immunity (unvaccinated), 2) Vaccine-induced immunity (vaccinated individuals without a COVID-19 history), and 3) Natural immunity + vaccine-induced immunity. These groups were matched by age and gender. We assessed the ability of individuals' serum to neutralize the Delta variant and compared the results of the different groups using a neutralization test followed by plaque-forming units. Results showed that 39% of individuals' serum with a history of COVID-19 (natural immunity, Group 1) could not neutralize the Delta variant, compared to 33% in vaccinated individuals without COVID-19 (vaccine immunity, Group 2). In contrast, only 7% of vaccinated individuals with a history of COVID-19 (natural + vaccine immunities) could not neutralize the Delta variant. We concluded that the effectiveness of the Ad5-nCoV vaccine to induce neutralizing antibodies against the Delta variant is comparable to that of natural infection (61% vs. 67%). However, in individuals with both forms of immunity (Group 3), it increased to 93%. Based on these results, despite the Ad5-nCoV vaccine originally being designed as a single-dose regimen, it could be recommended that even those who have recovered from COVID-19 should consider vaccination to boost their immunity against this variant.

Values in Context: The (Dis)connections Between Moral Foundations and Moral Conviction.

Moral foundations theory (MFT) argues that liberals and conservatives form different moral positions because liberals emphasize the values of harm and fairness, whereas conservatives emphasize the values of group loyalty, authority, and purity. In five studies (total N = 3,327), we investigated whether political orientation moderated the relationship between the perceived relevance of each moral foundation and moral conviction (i.e., the extent to which one perceives their attitude as based on morality) across four issues. Political differences in this relationship emerged but were inconsistent across issues and did not always align with the predictions of MFT or several other theoretical explanations. Our findings together with previous research indicate that MFT may do a better job predicting attitude position than it does predicting whether people perceive that their attitudes are moral convictions, and that some foundations may reflect conventional rather than moral values (e.g., authority).

Nanomedicine-mediated drug delivery for potential treatment of inflammatory bowel disease: a narrative review.

Background & aims: Inflammatory bowel disease (IBD) is a condition characterized by chronic inflammation of the gastrointestinal tract, manifesting as either Crohn's disease (CrD) or ulcerative colitis (UC). Current treatment options for CrD and UC primarily focus on symptom management. In recent years, advancements in nanotechnology have increased the clinical applicability of nanoparticles (NPs) in treating IBD. This review explores the current research on NP-mediated drug-delivery systems for IBD treatment and assesses its advantages and limitations. Results: The authors examine diverse nanomedicine applications for IBD and address the current challenges and prospects in the field to advance nanomediated therapies in the future. Conclusion: Innovative NP-based treatment strategies promise a reliable and effective approach to IBD management.

In vitro assessment of antibacterial and antiviral activity of three copper products after 200 rounds of simulated use.

Copper has well-documented antibacterial effects but few have evaluated it after prolonged use and against bacteria and viruses. Coupons from three copper formulations (solid, thermal coating, and decal applications) and carbon steel controls were subjected to 200 rounds simulated cleaning using a Wiperator™ and either an accelerated hydrogen peroxide, quaternary ammonium, or artificial sweat products. Antibacterial activity against S. aureus and P. aeruginosa was then evaluated using a modified Environmental Protection Agency protocol. Antiviral activity against coronavirus (229E) and norovirus (MNV-1) surrogates was assessed using the TCID50 method. Results were compared to untreated control coupons. One hour after inoculation, S. aureus exhibited a difference in log kill of 1.16 to 4.87 and P. aeruginosa a log kill difference of 3.39-5.23 (dependent upon copper product and disinfectant) compared to carbon steel. MNV-1 demonstrated an 87-99% reduction on each copper surfaces at 1 h and 99% reduction at 2 h compared to carbon steel. Similarly, coronavirus 229E exhibited a 97-99% reduction after 1 h and 90-99% after 2 h. Simulated use with artificial sweat did not hinder the antiviral nor the antibacterial activity of Cu surfaces. Self-sanitizing copper surfaces maintained antibacterial and antiviral activity after 200 rounds of simulated cleaning.

Mechanism of escape from the antibacterial activity of metal-based nanoparticles in clinically relevant bacteria: A systematic review.

The emergency of antibiotic-resistant bacteria in severe infections is increasing, especially in nosocomial environments. The ESKAPE group is of special importance in the groups of multi-resistant bacteria due to its high capacity to generate resistance to antibiotics and bactericides. Therefore, metal-based nanomaterials are an attractive alternative to combat them because they have been demonstrated to damage biomolecules in the bacterial cells. However, there is a concern about bacteria developing resistance to NPs and their harmful effects due to environmental accumulation. Therefore, this systematic review aims to report the clinically relevant bacteria that have developed resistance to the NPs. According to the results of this systematic review, various mechanisms to counteract the antimicrobial activity of various NP types have been proposed. These mechanisms can be grouped into the following categories: production of extracellular compounds, metal efflux pumps, ROS response, genetic changes, DNA repair, adaptative morphogenesis, and changes in the plasma membrane.

Microbiological Profi le of Periprosthetic Knee Infections in a Brazilian Unified Health System Hospital Specialized in Highly Complex Orthopedic Surgeries / Perfil microbiológico das infecções periprotéticas do joelho em um hospital do Sistema Único de Saúde especializado em cirurgias ortopédicas de alta complexidade

Resumo Este artigo objetiva compreender as implicações da pandemia da COVID-19 na prática do aleitamento materno e as ações de promoção da saúde no âmbito da atenção básica, a partir da percepção das mulheres lactantes. Estudo qualitativo, desenvolvido com 24 mulheres que amamentaram durante o primeiro ano da pandemia. Os dados foram analisados a partir da Análise de Conteúdo e interpretados à luz da Teoria Interativa da Amamentação. A pandemia repercutiu em vulnerabilidade da saúde mental das lactantes, dificuldades para a continuidade do aleitamento materno e inserção precoce de fórmulas infantis, adoção de medidas de prevenção contra a COVID-19 no ato da amamentação e mudanças no trabalho das lactantes. Além disso, foram identificadas fragilidades nas ações de promoção da saúde e no apoio ao binômio mãe-filho, devido à interrupção das consultas de puericultura. Conclui-se que, embora a maioria das participantes do estudo tenha mantido o aleitamento materno exclusivo nos seis primeiros meses, as ações de promoção da saúde infantil na atenção básica foram insatisfatórias, podendo repercutir negativamente na morbimortalidade infantil.

Abstract This article aims to understand the implications of the COVID-19 pandemic on breastfeeding and health promotion actions within primary care from the perception of breastfeeding women. This qualitative study was developed with 24 women who breastfed during the first year of the pandemic. Data were analyzed using Content Analysis and interpreted in the light of the Interactive Breastfeeding Theory (IBT). The pandemic affected the vulnerability of the mental health of breastfeeding women, entailed difficulties for the continuity of breastfeeding and early insertion of formulas, impacted COVID-19 preventive measures in breastfeeding, and produced changes in the work of breastfeeding women. Furthermore, areas for improvement were identified in health promotion actions and the mother-child binomial support due to the interruption of childcare visits. Actions to promote child health in primary care were unsatisfactory. However, most study participants maintained exclusive breastfeeding for the first six months, which could adversely affect child morbimortality.

Possibilidades e limites do Pré-natal do Homem em um município do Nordeste brasileiro / Possibilities and limits of Prenatal Care for Men in a city in Northeastern Brazil

Resumo O Pré-natal do Homem é uma estratégia para ampliar e promover a saúde dessas pessoas. Avaliou-se como as equipes de Saúde da Família (eSF) conduzem este artifício como estratégia de cuidado à população masculina em Recife-PE. Estudo avaliativo, transversal, qualitativo, envolvendo enfermeiros, médicos, cirurgiões-dentistas, técnicos de enfermagem e agentes comunitários de saúde. Aplicou-se um questionário semiestruturado seguido da realização de seis grupos focais com as eSF com maior número de respondentes na primeira etapa para aprofundar o desenvolvimento da estratégia. Foi realizada análise temática de conteúdo proposta por Bardin. A matriz de avaliação desenvolvida permitiu identificar as principais potencialidades e dificuldades encontradas na estrutura, processo de trabalho e resultados da estratégia. Observou-se que embora aceito como excelente estratégia, encontra-se resistência que perpassa desde questões estruturais às culturais, dificultando a proposta de ampliar o acesso às ações e aos serviços para promoção da saúde masculina, permanecendo o modelo biomédico. O cuidado se refere ao desdobramento da assistência já prestada às gestantes, mas encontra percalços limitantes para sua sustentabilidade.

Abstract Men's Prenatal Care is a strategy to expand and promote the health of these people. We evaluated how the Family Health teams (eSF) conduct this artifice as a care strategy for the male population in Recife-PE, Brazil. This evaluative, cross-sectional, qualitative study involved nurses, doctors, dentists, nursing technicians, and community health workers. We applied a semi-structured questionnaire, followed by six focus groups with the eSF with the largest number of respondents in the first stage to deepen the development of the strategy. The thematic content analysis proposed by Bardin was performed. The evaluation matrix developed identified the main strengths and difficulties in the strategy's structure, work process, and results. We observed that, while accepted as an excellent strategy, we identified a resistance that permeates from structural to cultural issues, hindering the proposal to expand access to actions and services to promote men's health, preserving the biomedical model. Care refers to the unfolding of care already provided to pregnant women but faces limiting obstacles for its sustainability.

Evidencias de validez y confiabilidad del Inventario de Trastornos de Ansiedad Generalizada en universitarios mexicanos / Evidence of validity and reliability of the Generalized Anxiety Disor-ders Inventory in Mexican university students

El presente estudio analiza las propiedades psicométricas, en hombres y mujeres universitarios, de la versión española propuesta por Blanco et al. (2017) para el Inventario de Trastornos de Ansiedad Generalizada. La mues¬tra total fue de 1220 participantes; 640 mujeres y 580 hombres, con una edad media de 20.40 años (DE= 1.92) y 20.54 años (DE= 2.04) respectivamente. Los análisis factoriales confirmatorios mostraron que una estructura trifactorial (síntomas cognitivos, trastornos del sueño y síntomas somáticos) es viable y adecuada para ambas poblaciones (mujeres y hombres) de acuerdo a los requisitos psicométricos establecidos. Además, la estructura factorial, las cargas factoriales y los interceptos se consideran invariantes en las dos poblaciones; sin embargo, existen diferencias entre las poblaciones para las medias de los factores síntomas cognitivos y síntomas somá¬ticos.

The present study analyses the psychometric properties, in university men and women, proposed for Blanco et al. (2017) to the Spanish version of the Generalized Anxiety Disorder Inventory. The overall sample consisted of 1220 subjects: 640 women and 580 men, with a mean age of 20.40 years (SD= 1.92) and 20.54 years (SD= 2.04) respectively. Psychometric analysis showed that a tri-factorial structure (cognitive symptoms, sleep disorders and somatic symptoms) was viable and adequate for both populations (men and woman) according to the established psychometric requirements. The results showed that factor structure, factor loadings and intercepts of the instrument could be considered invariant across groups; however, there are differences between groups for the means of factors cognitive anxiety and somatic symptoms.
