RESUMEN

Enteroparasitosis are diseases caused by parasitic agents present in the environment and in the gastrointestinal tract of living beings. In addition, they are still considered neglected diseases, but of great importance for public health, especially when they are related to secondary infections and currently their co-infection profile with COVID-19. The interaction of protozoa and/or helminths with the SARS-CoV-2 virus is timely and its signs and symptoms are confused with other pathogen relationships. In this way, this study aims to correlate the incidence of enteroparasitosis and COVID-19, in the pandemic period from 2020 to April 2022. This is a documentary and exploratory study of secondary data from laboratory tests of patients who were treated and diagnosed with COVID-19 and enteroparasitosis at Hospital Doutor Cloves Bezerra Cavalcante, Municipal Hospital of Bananeiras, Paraíba, Brazil. In the analysis of the database, a significant increase of approximately 48.85% in the incidence of COVID-19 cases from 2020 to 2021 stands out, remaining high until 2022. In contrast, cases of enteroparasites peaked at 48.74% in 2021, followed by an average reduction of 23.12%, with a deviation of 1.49%, in relation to the years 2020 and 2022. It was concluded that COVID-19 is predominantly associated with an increase in secondary infections, highlighting the crucial need to promote health education, improve basic sanitation and guarantee access to health services as essential components in combating the increase in parasitic infections, especially those related to viral pathologies.

As enteroparasitoses são enfermidades originadas por agentes parasitários presentes no meio ambiente e no trato gastrointestinal dos seres vivos. Ademais, ainda são consideradas doenças negligenciadas, porém de grande importância para a saúde pública, em especial, quando estão relacionadas com infecções secundárias e atualmente seu perfil de coinfecção com a COVID-19. A interação de protozoários e/ou helmintos com o vírus SARS-CoV-2 é oportuna e seus sinais e sintomas são confundidos com outras relações de patógenos. Desta maneira, este estudo visa correlacionar a incidência de enteroparasitoses e COVID-19, no período pandêmico de 2020 a abril de 2022. Trata--se de uma pesquisa documental e exploratória, de dados secundários dos exames laboratoriais de pacientes que foram atendidos e diagnosticados com COVID-19 e enteroparasitoses no Hospital Doutor Cloves Bezerra Cavalcante, Hospital Municipal de Bananeiras, Paraíba, Brasil. Na análise da base de dados, destaca-se um aumento significativo de aproximadamente 48,85% na incidência de casos de COVID-19 de 2020 a 2021, mantendo-se elevado até 2022. Em contraste, os casos de enteroparasitas atingiram um pico de 48,74% em 2021, seguido por uma redução média de 23,12%, com um desvio de 1,49%, em relação aos anos de 2020 e 2022. Conclui-se que a COVID-19 está predominantemente associada ao aumento de infecções secundárias, destacando a necessidade crucial de promover a educação em saúde, melhorar o saneamento básico e garantir o acesso aos serviços de saúde como componentes essenciais no combate ao aumento de infecções parasitárias, especialmente aquelas relacionadas a patologias virais.

RESUMEN

BACKGROUND: Penile squamous cell carcinoma (PSCC) is a rare malignancy. However, in developing countries the incidence rate is higher. The understanding of molecular alterations is essential for evaluating possible targets for more effective systemic therapies. METHODS: We retrospectively collected clinical data of metastatic PSCC (mPSCC) patients who had received at least one prior systemic treatment from 3 Brazilian hospitals. Tumor samples were evaluated using the next-generation sequencing (NGS) Foundation One DX and immunohistochemistry (IHC). The objective was to identify and describe somatic genomic alterations known to be functional or pathogenic and their association with survival outcomes. RESULTS: Twenty-three patients were identified, 22 and 18 patients had tumor samples analyzed by IHC and NGS, respectively. PD-L1 expression (CPS ≥ 1%) was positive in 14 patients (63.6%). Regarding the genomic alterations, 16 patients (88.9%) had some clinically relevant genomic alterations. TP53, TERT, CDKN2A, PIK3CA, NOTCH1, and CDKN2B loss were identified in 66.7%, 50%, 50%, 33.3%, 27.8%, and 22.2% of the patients, respectively. No MSI or TMB high (≥10 mutations/MB) cases were identified. NOTCH1 mutation was identified only in HPV-negative patients and it was associated with worse OS (yes: 5.5 vs no: 12.8 months, P = .049) and progression-free survival (yes: 5.5 vs no: 11.7 months, P = .032). CONCLUSION: This study demonstrated that molecular alterations in mPSCC from developing countries are similar to those from developed countries. Predictive biomarkers for immunotherapy response such as TMB high or MSI were not identified. Specific gene mutations may identify patients with worse prognoses and open new avenues for therapeutic development.

RESUMEN

Functional foods, and specifically probiotics, are important products present in retail worldwide. Probiotics comprise "live microorganisms that, when administered in adequate amounts, can confer a health benefit on the host". This study aimed to investigate the effect of culture on probiotic foods social representation. A total of 818 consumers from seven countries (Argentina, Brazil, Honduras, Mauritius, Mexico, Peru, and Slovenia) participated in the study. A free word association task was performed with the inductor term "probiotic food," followed by lemmatization, categorization, and prototypical analysis of the social representation. The results indicated that the term health was common in all countries studied, as well as other positive aspects such as benefits, well-being, and functional foods. This study helped to shed light and better understand the role of culture in the social representation of probiotics.

RESUMEN

OBJECTIVE: To assess the effect of occupational exposure to isoflurane on the sperm quality of mice, and to investigate whether cessation of exposure can restore seminal quality. METHODS: Mice were exposed to 50 ppm of isoflurane for 5 hours per day over a 30-day period. Following this exposure, they were euthanized at predetermined post-exposure intervals, and their sperm samples were analyzed for kinetics and viability parameters. RESULTS: Occupational exposure to isoflurane can adversely affect sperm at 50 ppm, a concentration deemed safe by international occupational health conventions in some countries. These effects are marked by oxidative stress, mitochondrial dysfunction, and genomic damage, alongside alterations in sperm kinetics and acrosomal integrity. Furthermore, cessation of exposure doesn't guarantee restoration of cellular quality. CONCLUSIONS: Isoflurane at 50 ppm, previously deemed safe by some countries, impairs sperm kinetics and viability, potentially directing the spermatogenic process towards infertility and apoptosis.

RESUMEN

INTRODUCTION: The present study investigated the impact of immune recovery and the duration of antifungal adherence in the consolidation phase of disseminated histoplasmosis (DH) in acquired immune deficiency syndrome (AIDS) patients living in a hyperendemic area in northeastern Brazil. MATERIAL AND METHODS: Sixty-nine patients with DH/AIDS, admitted to the São José Hospital between 2010 and 2015, who continued histoplasmosis consolidation therapy at the outpatient clinic were studied. The follow-up duration was at least 24 months. RESULTS: Sixty-eight patients used itraconazole 200-400 mg/day or amphotericin B deoxycholate weekly during the consolidation phase, and six patients relapsed during follow-up. The overall median duration of consolidation antifungal use was 250 days [IQR 101 - 372]. Antifungal withdrawal by medical decision occurred in 41 patients (70.7 %) after a median of 293 days [IQR 128 - 372] of use; 16 patients discontinued by their own decision, with a median of 106 days [IQR 37 - 244] of therapy; three patients had no information available, and nine continued on AF therapy. The median CD4+ T-cell count in the group without relapse was 248 cells/µL [IQR 115-355] within 6 months after admission; conversely, in the relapse group, the median cell count remained below 100 cells/µL. Irregular adherence to highly active antiretroviral therapy (HAART) was the leading risk factor associated with relapse and death (p< 0.01). DISCUSSION: The regular use of HAART, combined with immune recovery, proved to be highly effective in preventing relapses in DH/AIDS patients, suggesting that long-term antifungal therapy may not be necessary.

RESUMEN

This study examines the effects of Roundup Transorb® (RDT) exposure on reproductive functions and ovarian miRNA expression in Austrolebias charrua. Exposure to RDT (at 0.065 or 5 mg. L-1 for 96 h) significantly disrupts fertility, evidenced by changes in fertilization rates and egg diameter. Profiling of ovarian miRNAs identified a total 205 miRNAs in A. charrua. Among these, three miRNAs were upregulated (miR-10b-5p, miR-132-3p, miR-100-5p), while ten miRNAs were downregulated (miR-499-5p, miR-375, miR-205-5p, miR-206-3p, miR-203a-3p, miR-133b-3p, miR-203b-5p, miR-184, miR-133a-3p, miR-2188-5p) compared to non-exposed fish. This study reveals that differentially expressed miRNAs are linked to molecular pathways such as steroid hormone biosynthesis, lipid and carbohydrate metabolism, bioenergetics, and antioxidant defense. It also analyzes molecular interactions between miRNAs and target genes during RDT exposure in annual killifish, providing insights into biomarkers in ecotoxicology. Moreover, it provides scope for developing environmental health assessment models based on epigenomic endpoints, supporting the protection of biodiversity and ecosystem services through the quantification of stress responses in living organisms exposed to pesticides.

RESUMEN

BACKGROUND: Ventilator-associated tracheobronchitis is a common condition among invasively ventilated patients in intensive care units, for which the best treatment strategy is currently unknown. We designed the VATICAN (Ventilator-Associated Tracheobronchitis Initiative to Conduct Antibiotic Evaluation) trial to assess whether a watchful waiting antibiotic treatment strategy is noninferior to routine antibiotic treatment for ventilator-associated tracheobronchitis regarding days free of mechanical ventilation. METHODS: VATICAN is a randomized, controlled, open-label, multicenter noninferiority trial. Patients with suspected ventilator-associated tracheobronchitis without evidence of ventilator-associated pneumonia or hemodynamic instability due to probable infection will be assigned to either a watchful waiting strategy, without antimicrobial administration for ventilator-associated tracheobronchitis and prescription of antimicrobials only in cases of ventilator-associated pneumonia, sepsis or septic shock, or another infectious diagnosis, or to a routine antimicrobial treatment strategy for seven days. The primary outcome will be mechanical ventilation-free days at 28 days, and a key secondary outcome will be ventilator-associated pneumonia-free survival. Through an intention-to-treat framework with a per-protocol sensitivity analysis, the primary outcome analysis will address noninferiority with a 20% margin, which translates to a 1.5 difference in ventilator-free days. Other analyses will follow a superiority analysis framework. CONCLUSION: The VATICAN trial will follow all national and international ethical standards. We aim to publish the trial in a high-visibility general journal and present it at critical care and infectious disease conferences for dissemination. These results will likely be immediately applicable to the bedside upon trial completion and will provide information with a low risk of bias for guideline development.

RESUMEN

IMPORTANCE AND OBJECTIVES: To compare the 18-month survival between patients with newly diagnosed cancer discharged home after early unplanned ICU admission and those without early unplanned ICU admission; we also evaluated the frequency and risk factors for early unplanned ICU admission. DESIGN: Observational study with prospectively collected data from September 2019 to June 2021 and 18 months follow-up. SETTING: Single dedicated cancer center in São Paulo, Brazil. PARTICIPANTS: We screened consecutive adults with suspected cancer and included those with histologically proven cancer from among 20 highly prevalent cancers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: The exposure was early unplanned ICU admission, defined as admission for medical reasons or urgent surgery during the first 6 months after cancer diagnosis. The main outcome was 18-month survival after cancer diagnosis, and the main analysis was Cox's proportional hazards model adjusted for confounders and immortal time bias. Propensity score matching was used in the sensitivity analysis. We screened 4738 consecutive adults with suspected cancer and included 3348 patients. Three hundred twelve (9.3%) had early unplanned ICU admission, which was associated with decreased 18-month survival both in the unadjusted (hazard ratio, 4.03; 95% CI, 2.89-5.62) and adjusted (hazard ratio, 1.84; 95% CI, 1.29-2.64) models. The sensitivity analysis confirmed the results because the groups were balanced after matching, and the 18-month survival of patients with early ICU admission was lower compared with patients without early ICU admission (87.0% vs. 93.9%; p = 0.01 log-rank test). Risk factors for early unplanned ICU admission were advanced age, comorbidities, worse performance status, socioeconomic deprivation, metastatic tumors, and hematologic malignancies. CONCLUSIONS: Patients with newly diagnosed cancer discharged home after early unplanned ICU admission have decreased 18-month survival compared with patients without early unplanned ICU admission.

RESUMEN

Regeneration is a remarkable characteristic of the skeletal muscle. Triggered by common lesions, regeneration is stimulated resulting in muscle fiber repair and restoration of muscle homeostasis in normal muscle. In genetic dystrophic muscle, the cycle of degeneration/regeneration is an endless loop that leads to impaired regeneration and substitution of muscle fibers by connective and adipose tissue, causing muscle weakness. Identification and characterization of muscle regeneration steps can help discover potential therapy targets for muscle diseases and aging. Muscle regeneration markers such as the number of satellite cells in the muscle, the proportion of activated satellite cells, and the quantity of regenerating muscle fiber can be quantified using immunolabeling.Here we are presenting a quantitative method to measure muscle regeneration that can be applied to different proposals. To demonstrate the protocol applicability, we used models for acute and chronic muscle injuries. As model of acute degeneration, a wild-type C57BL6 mice with muscle injury induced by electroporation was used, and the muscle was analyzed after 5 and 10 days post-injury. DMDmdx mouse muscle was used as a model of chronic degeneration. The methodologies presented here are among the gold standard methodologies for muscle regeneration analysis and can be easily applied to any type of muscle regeneration study.

RESUMEN

In viticulture, choosing the most suitable rootstock for a specific scion cultivar is an efficient and cost-effective way to increase yield and enhance the physicochemical characteristics of the fruit. The objective of this study was to evaluate the agronomic performance of the 'BRS Tainá' grapevine on different rootstocks under the conditions of the Sub-Middle São Francisco Valley. The main experimental factor consisted of eight rootstocks (IAC 313, IAC 572, IAC 766, 101-14 MgT, Paulsen 1103, Ramsey, SO4, and Teleki 5C), arranged in randomized blocks with four replicates. The experiment was conducted over four production cycles, from 2021 to 2023, in a commercial crop area in Petrolina, PE, Brazil. There were significant effects of rootstocks for the yield and number of bunches per plant, as well as berry length and firmness. 'BRS Tainá' achieved the highest yield (22.2 kg per plant) when grafted onto the Paulsen 1103 rootstock, which was superior to the yield on 101-14 MgT, IAC 313, and IAC 572 rootstocks. The highest number of bunches (88) was obtained with 'BRS Tainá' grafted on Paulsen 1103, while the lowest number (63) was obtained on IAC 572; both these rootstocks were not significantly different from the other rootstocks. For all scion-rootstock combinations, the mean values for soluble solid (SS) content, titratable acidity (TA), and the SS/TA ratio were similar to those previously described for 'BRS Tainá', meeting the commercialization standard. The results for the yield and number of bunches per plant indicate the suitability of grafting 'BRS Tainá' on Paulsen 1103 under the semi-arid tropical conditions of the São Francisco Valley.

RESUMEN

OBJECTIVE: The objective of this study was to conduct an integrative review, addressing the key findings, biological functions, and clinical significance of these biomolecules in solid tumors. METHODS: This document analyzes the main data on the involvement of snoRNAs in solid tumors. For this, Pubmed and Science direct were used, with keywords. Additionally, a search for the host gene was conducted using the snoDB tool, and its chromosomal location was identified using the Hugo Gene Nomenclature Committee (HGNC). RESULTS: According to research conducted in the literature, the majority of snoRNAs were found to be overexpressed and described as regulators of processes such as invasion, cellular proliferation, apoptosis, and migration. They are associated with clinical prognostic factors such as metastasis and worse survival. CONCLUSION: Therefore, it is essential to expand the investigation of snoRNAs in oncology across different types of tumors. The utilization of these biomolecules may pave the way for innovative clinical applications, such as their use in the early detection of neoplasms in non-invasive samples and as therapeutic targets. Broadening research on snoRNAs across various tumor types is crucial.

RESUMEN

INTRODUÇÃO: A avaliação da deformação miocárdica do AE por técnica de speckle tracking tem sido de crescente interesse na avaliação funcional dessa câmara. Inicialmente, utilizou-se a adaptação da ferramenta direcionada à análise do ventrículo esquerdo para a análise da câmara atrial, que apresenta particularidades anatômicas. Mais recentemente, ferramentas dedicadas à análise dessa câmara cardíaca têm sido disponibilizadas comercialmente. Os valores de normalidade assumidos baseiam-se em estudos com diferentes ferramentas e softwares. OBJETIVOS: Avaliar o nível de concordância entre as ferramentas dedicada e não dedicada ao átrio esquerdo em software disponível comercialmente (GE EchoPAC Version 204). MÉTODOS: Estudo unicêntrico, transversal, com avaliação ecocardiográfica de 81 pacientes com ecocardiograma transtorácico bidimensional registrado com aquisições completas. Utilizou-se a padronização de técnica por recomendações da American Society of Echocardiography de 2018. Para ambas as ferramentas, foi empregado o método biplanar para obtenção dos valores de strain global longitudinal do AE de seus componentes reservatório (R), conduto (CD) e contrátil (CT). Para análise de concordância entre as ferramentas não dedicada e dedicada à medida de strain AE, realizou-se cálculo da diferença absoluta média (d.a.m.) e análise de Bland-Altman, com descrição da diferença média e dos limites de concordância (±1,96 desvio-padrão). Para análise de variabilidades intraobservador e interobservador foram descritos diferenças absolutas médias e desvio-padrão entre as medidas, bem como empregado o coeficiente de correlação intraclasse (CCI). RESULTADOS: Os valores médios obtidos para strain AE R, CD e CT, não apresentaram diferença significativa quando comparados os softwares não dedicado e dedicado: - strain AE R: 33.2 ± 8.4 vs 33 ± 7.9, p: 0.52, d.a.m.: 1,68 ± 1.28; - strain AE CD: -16.4 ± 5.5 vs -16.2 ± 5.2; p: 0.48; d.a.m.: 2,12 ± 2,10 - strain AE CT: -16.9 ± 5.1 vs -16.7 ± 5.3; p: 0.51; d.a.m.: 1,58 ± 1,31 Para avaliação de variabilidade intraobservador e interobservador das medidas de strain AE R, CD e CT, repetiram-se as análises de forma aleatória e cega aos resultados iniciais após pelo menos quatro semanas da primeira medida em 16 casos aleatórios, com concordância elevada. CONCLUSÃO: Os valores médios obtidos para o strain AE não diferiram significativamente com a escolha da ferramenta dedicada ou não dedicada ao AE em software disponível comercialmente.

RESUMEN

INTRODUÇÃO: O átrio esquerdo (AE) exerce importante papel no enchimento ventricular esquerdo (VE) e na manutenção de pressões normais no leito capilar pulmonar. A rigidez atrial esquerda pode interferir nessa dinâmica e ser estimada invasivamente por medidas diretas de pressões e volumes do AE. A ecocardiografia, por meio da relação entre E/e´ e a medida do strain AE reservatório (R), permite a avaliação não invasiva desse parâmetro. OBJETIVO: Correlacionar o índice de rigidez atrial esquerda (IRAE) ecocardiográfico com medidas invasivas das pressões diastólica final (PD2VE) e pré-contração atrial (pré-A VE) em coronariopatas com fração de ejeção do VE (FEVE) preservada, com avaliação da acurácia preditiva de elevações dessas pressões de enchimento. METODOLOGIA: Estudo observacional, transversal, unicêntrico, com pacientes que realizaram eletivamente estudo hemodinâmico com evidência de doença arterial coronária significativa e ecocardiograma transtorácico no laboratório de hemodinâmica imediatamente antes do cateterismo. O strain AE R foi obtido por técnica de speckle tracking bidimensional por ferramenta dedicada ao AE (software GE EchoPAC) e a relação E/e´ média foi adotada para inferência da pressão média do AE. Valores acima de 16 mmHg e 12 mmHg foram utilizados como cortes para definir medidas invasivas de PD2VE e pré-A VE como elevadas, respectivamente. Análises estatísticas para comparação entre medidas de tendência central, correlação bivariável e curva ROC foram realizadas (IBM SPSS Statistics 20). RESULTADOS: A amostra final foi constituída por 81 pacientes, com idade média de 61±8 anos, 66% do sexo masculino, FEVE média de 63,8±4.6%. O IRAE apresentou correlação significativa e moderada com a PD2VE (r Spearman: 0.61, p<0.001) e a pré-A VE (r Spearman: 0.67, p<0.001). Houve diferença significativa entre os valores medianos de IRAE no grupo com pré-A VE normal [0.21 (0.17-0.26)] e elevada [0.45 (0.36-0.65; p<0.001)] bem como no grupo com PD2VE normal [0.21 (0.16-0.25)] e elevada [0.39 (0.27-0.54; p<0.001)]. A área sob a curva ROC para predição de PD2VE alta foi de 0.86. Para a discriminação de pré-A VE alta a área sob a curva foi de 0.93, superior a de parâmetros tradicionais como E/e´ média isoladamente (0.83) e volume indexado do AE (0.70). CONCLUSÃO: O IRAE é útil na discriminação hemodinâmica das pressões de enchimento de pacientes coronariopatas com FEVE preservada, com desempenho superior a de tradicionais parâmetros ecocardiográficos.

RESUMEN

The study aimed to conduct in vitro biological assessments of hydantoin and thiohydantoin compounds against mature Schistosoma mansoni worms, evaluate their cytotoxic effects and predict their pharmacokinetic parameters using computational methods. The compounds showed low in vitro cytotoxicity and were not considered hemolytic. Antiparasitic activity against adult S. mansoni worms was tested with all compounds at concentrations ranging from 200 to 6.25 µM. Compounds SC01, SC02, and SC03 exhibited low activity. Compounds SC04, SC05, SC06 and SC07 caused 100 % mortality within 24 h of incubation at a concentration of 100 and 200 µM. Thiohydantoin SC04 exhibited the highest activity, resulting in 100 % mortality after 24 h of incubation at a concentration of 50 µM and IC50 of 28 µM. In the ultrastructural analysis (SEM), the compound SC04 (200 µM) induced integumentary changes, formation of integumentary blisters, and destruction of tubercles and spicules. Therefore, the SC04 compound shows promise as an antiparasitic against S. mansoni.

RESUMEN

INTRODUCTION: Hospital-associated infections (HAIs) are associated with increased mortality and prolonged hospital length-of-stay (LOS). Although some studies have shown that HAIs are associated with increased costs, these studies only used cost estimates, were carried out in a small number of centres, or only in high-income countries. METHODS: We carried out a prospective cohort study in ten Brazilian intensive care units (ICUs) selected from a collaborative platform study (IMPACTO MR). We included all patients aged 18 years or older admitted from October 2019 to December 2021 and who had an ICU LOS of at least two days. The costs were adjusted for official inflation until December 2022 and converted into international dollars using the 2021 purchasing power parity (PPP) conversion rate. We used a propensity score matching method to compare patients with HAIs and patients without HAIs, and patients with and without ventilator-associated pneumonia (VAP), central-line bloodstream infection (CLABSI), catheter-associated urinary tract infection (CA-UTI) and multidrug-resistant (MDR) HAIs. RESULTS: We included 7,953 patients in the study, of whom 574 (7.2%) had an HAI during their ICU stay. After propensity-score matching, patients with HAIs had ICU costs that were more than three times higher than those of patients without HAIs [$ 19,642 (IQR; 12,884-35,134) vs. 6,086 (IQR; 3,268-12,550); p <0.001). Patients with VAP, CLABSI, and CA-UTI, but not with MDR-HAIs also had higher total ICU costs. CONCLUSIONS: HAIs acquired in the ICU are associated with higher ICU costs. These findings were consistent across specific types of infection.

RESUMEN

Analyses of ancient DNA typically involve sequencing the surviving short oligonucleotides and aligning to genome assemblies from related, modern species. Here, we report that skin from a female woolly mammoth (†Mammuthus primigenius) that died 52,000 years ago retained its ancient genome architecture. We use PaleoHi-C to map chromatin contacts and assemble its genome, yielding 28 chromosome-length scaffolds. Chromosome territories, compartments, loops, Barr bodies, and inactive X chromosome (Xi) superdomains persist. The active and inactive genome compartments in mammoth skin more closely resemble Asian elephant skin than other elephant tissues. Our analyses uncover new biology. Differences in compartmentalization reveal genes whose transcription was potentially altered in mammoths vs. elephants. Mammoth Xi has a tetradic architecture, not bipartite like human and mouse. We hypothesize that, shortly after this mammoth's death, the sample spontaneously freeze-dried in the Siberian cold, leading to a glass transition that preserved subfossils of ancient chromosomes at nanometer scale.

RESUMEN

The persistence of the human papillomavirus type 16 (HPV16) infection on the cervical epithelium contributes to the progression of cervical cancer. Studies have demonstrated that HPV16 genetic variants may be associated with different risks of developing cervical cancer. However, the E5 oncoprotein of HPV16, which is related to several cellular mechanisms in the initial phases of the infection and thus contributes to carcinogenesis, is still little studied. Here we investigate the HPV16 E5 oncogene variants to assess the effects of different mutations on the biological function of the E5 protein. We detected and analyzed the HPV16 E5 oncogene polymorphisms and their phylogenetic relationships. After that, we proposed a tertiary structure analysis of the protein variants, preferential codon usage, and functional activity of the HPV16 E5 protein. Intra-type variants were grouped in the lineages A and D using in silico analysis. The mutations in E5 were located in the T-cell epitopes region. We therefore analyzed the interference of the HPV16 E5 protein in the NF-kB pathway. Our results showed that the variants HPV16E5_49PE and HPV16E5_85PE did not increase the potential of the pathway activation capacity. This study provides additional knowledge about the mechanisms of dispersion of the HPV16 E5 variants, providing evidence that these variants may be relevant to the modulation of the NF-κB signaling pathway.

RESUMEN

OBJECTIVES: to contribute to the change in understandings and knowledge of the popular system among riverine women about female intimate self-care before and after the application of an educational dynamic. METHODS: a qualitative-participative study based on the Sunrise Model. Twenty women registered at a Basic Health Unit on the Combu island, state of Pará, Brazil, participated in the second half of 2022. Semi-structured interviews were conducted before and after the educational dynamic; followed by reflective inductive analysis. RESULTS: these are pointed out: a female mechanism of generational education; the cultural act of bathing as synonymous with intimate self care and disease prevention; intimate care with medicinal herbs; lack of professional system approach to the topic; fear of using "muddy water"; and lack of financial resources to purchase specific products for genitourinary care. FINAL CONSIDERATIONS: companionship and social factors drive intimate self-care; however, riverine women experience taboos, ignorance, and poverty.

Background: A subcutaneous implantable cardioverter-defibrillator (S-ICD) is an alternative to a transvenous implantable cardio defibrillator (TV-ICD). An S-ICD reduces the risk of transvenous lead placement. However, further research is required to determine how S-ICDs affect patients with hypertrophic cardiomyopathy (HCM). In this study, we investigated the comparative efficacy and safety of S-ICDs versus TV-ICDs in HCM. Methods: On December 6th, 2023, we performed a comprehensive search of the PubMed, Embase, Scopus, and Cochrane databases to identify randomized clinical trials (RCTs) and observational studies comparing S-ICDs with TV-ICDs in HCM patients published from 2004 until 2023. No language restrictions were applied. The primary outcome was appropriate shocks (AS), with inappropriate shocks (IAS), and device-related complications considered as secondary outcomes. Odds ratios (ORs) and 95% confidence intervals (CIs) were pooled using a random effects model. The ROBINS-I tool was used to assess the risk of bias of the studies. Results: The search yielded 1,114 records. Seven studies comprising 4,347 HCM patients were included, of whom 3,325 (76.0%) had TV-ICDs, and 1,022 (22.6%) had S-ICDs. There were 2,564 males (58.9%). The age range was from 39.1 to 49.4 years. Compared with the TV-ICD group, the S-ICD cohort had a significantly lower incidence of device-related complications (OR 0.52; 95% CI: 0.30-0.89; P=0.02; I2=4%). Contrastingly, there were no statistically significant differences in the occurrences of AS (OR 0.49; 95% CI: 0.22-1.08; P=0.08; I2=75%) and IAS (OR 1.03; 95% CI: 0.57-1.84; P=0.93; I2=65%) between the two device modalities. In the analysis of the overall risk of bias in the studies, we found 42% of them with several, 28% with moderate, and 14% with low risk of bias. Conclusions: In HCM patients, S-ICDs were associated with a lower incidence of device-associated problems than TV-ICDs. AS and IAS incidence rates were similar between groups. These findings may assist clinicians in determining the most suitable device for treating patients with HCM.
