Congenital Apical Left Ventricular Aneurysm.

A 17-year-old male was referred for evaluation by Pediatric Cardiology following a pre-sports medical screening, which revealed abnormal ventricular repolarization (negative T wave from V3-V6) on a 12-lead ECG. For 8 years, he has been a competitive football player. There was no relevant personal or family medical history, and he denied any prior cardiovascular symptoms. His cardiovascular physical examination was normal. In the initial assessment, a transthoracic echocardiogram was conducted, revealing an apical aneurysm of the left ventricle (LV) with regional dyskinesia, accompanied by mild mitral regurgitation. The examination also demonstrated globally preserved left ventricular systolic function, with no images suggestive of vegetations or intracardiac thrombi found. For further anatomical and myocardial characterization, a cardiac magnetic resonance (CMR) was performed. The results revealed a wide apical aneurysm of the LV, predominantly lateral, with thin walls, ridges within the outpouching, and local dyskinesia. No areas of late gadolinium enhancement (LGE) were found, suggestive of fibrosis, anomalous infiltration, or scar from a previous infarction. After excluding other etiologies, the diagnosis of a congenital ventricular aneurysm was determined. This is a very rare condition (0.12%) with a wide and variable clinical presentation, ranging from benign arrhythmias to sudden death. Various imaging techniques aid in its diagnosis, with CMR being particularly useful for excluding inflammation and cardiomyopathies, identifying LGE, and evaluating left ventricular volumes and function. There is no standard treatment, and controversy surrounds indications for surgical intervention. If a conservative approach is adopted, measures aimed at preventing endocarditis and embolism must be considered.

The use of genus-level determinations and biovolume classes as surrogates to indicate environmental drivers of stream diatom communities in the Brazilian Pampa.

The demand for low-cost and time-efficient biomonitoring and ecological assessment strategies has increased due to threats to biodiversity. We evaluated the ability of surrogates (genera and biovolume classes) to access information provided by diatom species. Moreover, we investigated whether the relative importance of spatial and environment on diatom communities identified at the genus or classified at biovolume classes reflects the ecological responses at the species. We used biotic, environmental, and spatial data from Pampa streams. We employed Procrustes analysis to detect whether the spatial variation of communities at the species level was represented by the surrogates and variation partitioning to evaluate the relative importance of spatial and environment. We found high congruence between the surrogates and diatom species communities. Furthermore, whilst both spatial and environment were important to explain species composition, only the environment was important for both surrogates. We suggest that the use of genus-level determinations can provide information about the environmental relationships of species, whereas biovolume classes may be useful to detect changes in diatom communities. These results are a first step to seek for strategies aiming to simplify biological monitoring and assessments at pampean streams, especially considering the demand for the identification of organisms at the species.

The Protective Effect of Juçara Fruit (Euterpe edulis Martius) Extracts on LPS-Activated J774 Macrophages.

This study investigated the anti-inflammatory effect of hydrophilic and lipophilic extracts from juçara fruits (Euterpe edulis Martius) through measurement of nitric oxide (NOx) and cytokines (IL-12p70, TNF-α, INF-γ, MCP-1, IL-6, and IL-10). J774 macrophages were stimulated with lipopolysaccharides (1 µg/mL) and treated with various concentrations (1-100 µg/mL) of juçara fruits extracts from crude extracts, and hexane, dichloromethane, ethyl acetate, and butanol fractions. Potential relationships between the phenolic composition of the extracts determined by LC-ESI-MS/MS and their anti-inflammatory capacity were also evaluated. Hexane and dichloromethane fractions inhibited NOx and IL-12p70 while increased IL-10. Hexane fractions also decreased IL-6 and IFN-γ production. Hexane and dichloromethane fractions showed a higher number of phenolic compounds (32 and 34, respectively) than the other extracts tested and were also the only ones that presented benzoic acid and pinocembrin. These results suggest juçara fruits compounds as potential anti-inflammatory agents, especially those of a more apolar nature.

Surgical Management Of Congenital Thoracic Disorders: A 15-Year Center Experience.

INTRODUCTION: Congenital thoracic disorders represent a spectrum of fetal lung bud development abnormalities, which may affect breathing capacity and quality of life. We aim to evaluate the impact of surgery in the treatment of 4 major congenital conditions. MATERIALS AND METHODS: We performed a retrospective cohort analysis of patients who underwent surgical treatment in our tertiary center, from 2007 to 2022. RESULTS: Over the 15-year period, we treated 33 patients, with a male predominance of 55%. 22 patients (67%) were asymptomatic. When symptomatic, the recurrence of respiratory infections was the most common clinical presentation (18%). In 13 patients (39%), diagnosis was achieved through fetal ultrasonography. This study encompassed 13 patients with pulmonary sequestration (39%), 11 patients with bronchogenic cysts (33%), 7 patients with congenital pulmonary airway malformation (21%) and 2 patients with congenital lobar emphysema (6%). Considering solely lung malformation conditions, we accounted 22 patients with a median age of 3 [1-67] years-old. Surgery comprised bilobectomy (9%), lobectomy (77%), lobectomy with wedge resection (5%), segmentectomy (5%) and wedge resection (5%). Concerning bronchogenic cysts, we treated 11 patients with a median age of 19 [14-66] years-old. We identified 1 hilar, 1 intrapulmonary and 9 mediastinal lesions, of which 4 were paraesophageal, 4 were subcarinal and 1 was miscellaneous. Overall, surgery was conducted by thoracotomy in 61% of patients, VATS in 33% and RATS in 6%. The median drainage time was 3 [1-40] days and median hospital stay was 4 [1-41] days. There were no cases of mortality. Ensuing, 94% of patients experienced clinical improvement after surgery. CONCLUSION: Early diagnosis of congenital thoracic malformations increased considerably with the improvement in imaging technology and prenatal screening. Treatment may include expectant conservative treatment. However, in selected cases, surgery may play an important role in symptomatic control and prevention of disease progression.

Effect of hydrofluoric acid concentration and aging on the bond strength ceramics to a resin cement.

This study evaluated the influence of hydrofluoric acid (HF) concentration and thermal cycling on the microshear bond strength (µSBS) of a resin luting agent to IPS e.max® CAD and Rosetta® SM. Ceramic specimens (12.0 x 14.0 x 1.5mm) were randomized into 8 groups (n=10) according to HF concentration, commercial brand, and aging. Immediately after polishing, and etching, all specimens were silanized and a layer of adhesive was applied. A PVS mold of 3 mm thickness and 10mm diameter with (four) 1.0mm holes was fabricated, placed on each specimen, and then filled with a resin luting agent. Half of the specimens were subjected to the µSBS test using an Instron at a speed of 1.0 mm/min, following a 24-hour storage in deionized water at 37ºC. The remaining specimens were subjected to thermal cycling (5ºC-55ºC, 30 seconds per bath) and µSBS. The data were evaluated utilizing a three-way ANOVA and Tukey's post-hoc test (α=0.05). Significant differences were found for HF concentration and aging (p<0.0001). No significant difference in µSBS was found for commercial brands (p=0.085). The interaction between brand and HF concentration (p=0.358), brand and aging (p=0.135), and HF concentration and aging (p=0.138) were not statistically significant. The triple interaction among these factors was not statistically significant (p=0.610). In conclusion, the bond strength is affected by the HF concentration. No statistical difference was observed between the two ceramics. Thermal cycling significantly reduced µSBS.

POESIT recommendations on management of body-identical hormones in menopausal symptoms.

Many women seek treatment to improve menopausal vasomotor symptoms (VMS). The selection of women most likely to benefit from menopause hormone therapy (MHT) is crucial in clinical practice. There is general agreement that women younger than 60 years or who initiate MHT within the first 10 years of menopause, with no contraindications, have greater benefits considering symptomatic relief and additional advantages. This group may have the advantage of protection from osteoporosis and from other chronic diseases that affect postmenopausal women, namely cardiovascular disease (CVD). Cumulating evidence supports MHT for symptomatic women. However, inadequate use according to the needs of symptomatic women led to a burden of suffering worldwide. In recent years, the emergent use of non-regulated body-identical hormones (non-rBHT) can expose patients to potential harms. These hormone preparations are not regulated through the same tests of safety, efficacy or dosing consistency as regulated-BHT (r-BHT). The POESIT (Portugal + Spain + Italy) recommendations highlight the use of 17ß-estradiol (E2) and micronized progesterone (P4) as the real r-BHT. In addition, the group emphasizes as an example the data from the REPLENISH study with 1 mg E2/100 mg P4. The combination of the two hormones in one convenient pill showed a clear reduction or elimination of hot flashes and an improvement in sleep quality and, consequently, quality of life. At the same time, this combination has shown high rates of amenorrhea and no significant impact on lipid, glucose or coagulation parameters. Both the REPLENISH study and a real-life retrospective study pointed to the possibility of a lower risk of venous thromboembolism (VTE) with this formulation than with other combinations.

Noncomplex ventricular arrhythmia associated with greater freedom from recurrent ectopy at 1 year after mitral repair surgery.

Objective: The effect of mitral valve (MV) surgery on the natural history of ventricular arrhythmia (VA) in patients with arrhythmic MV prolapse remains unknown. We sought to evaluate the cumulative incidence of VA at 1 year after surgical mitral repair. Methods: A retrospective review of progressively captured data identified 204 consecutive patients who underwent elective MV repair for significant degenerative mitral regurgitation as a first-time cardiovascular intervention in a quaternary reference center between January 2018 and December 2020. A subset of 62 consecutive patients with diagnosed arrhythmic MV prolapse was further evaluated for recurrent VA after MV repair. Results: The median age was 62 years (range, 27-77 years) and 26 of 62 (41.9%) were female. The median time from initial mitral regurgitation/MV prolaspe diagnosis-to-referral was 13.8 years (interquartile range [IQR], 5.4-25) and from VA diagnosis-to-referral was 8 years (IQR, 3-10.6). Using the Lown-Wolf classification, complex VA (Lown grade ≥3) was identified in 36 of 62 patients (58%) at baseline, whereas 8 of 62 (13%) had a cardioverter/defibrillator implanted for primary (4/8) or secondary (4/8) prevention. Left ventricular myocardial scar was confirmed in 23 of 34 (68%) of patients scanned at baseline. The prevailing valve phenotype was bileaflet Barlow (59/62; 95.2%). All patients underwent surgical MV repair by the same team. Surgical repair was stabilized with an annuloplasty prosthesis (median size 36 mm [IQR, 34-38]). Concomitant procedures included tricuspid valve repair (51/62; 82.3%), cryo-maze ± left atrial appendage exclusion (14/62, 23%), and endocardial cryoablation of VA ectopy (4/62; 6.5%). The 30-day and 1-year freedom from recurrent VA were 98.4% and 75.9%, respectively. Absent VA after mitral repair was uniformly observed in patients with minor VA at baseline. Absent VA after mitral repair was uniformly observed in patients with minor VA preoperatively. Complex baseline VA was the strongest predictor of recurrent VA (hazard ratio, 10.8; 95% confidence interval, 1.4-84.2; P = .024), irrespective of myocardial fibrosis. Conclusions: In a series of 62 consecutive patients operated electively for arrhythmic mitral prolapse, VA remained undetected in 75.9% of patients at 1 year. Freedom from recurrent VA was greater among patients without complex VA preoperatively, whereas baseline Lown grade ≥3 was the strongest independent risk factor for recurrent VA at 1 year. These findings attest to the importance of early recognition and prompt referral of patients with mitral prolapse and progressive VA to specialty interdisciplinary care.

Beyond STEMI-NSTEMI Paradigm: Dante Pazzanese's Proposal for Occlusion Myocardial Infarction Diagnosis. / Além do Paradigma IAMCSST-IAMSSST: Proposta do Instituto Dante Pazzanese para o Diagnóstico de Oclusão Coronariana Aguda.

Although the existing framework for classifying acute myocardial infarction (AMI) into STEMI and NSTEMI has been beneficial, it is now considered to be falling short in addressing the complexity of acute coronary syndromes. The study aims to scrutinize the current STEMI-NSTEMI paradigm and advocate for a more nuanced framework, termed as occlusion myocardial infarction (OMI) and non-occlusion myocardial infarction (NOMI), for a more accurate diagnosis and management of AMI. A comprehensive analysis of existing medical literature was conducted, with a focus on the limitations of the STEMI-NSTEMI model. The study also outlines a new diagnostic approach for patients presenting with chest pain in emergency settings. The traditional STEMI-NSTEMI model falls short in diagnostic precision and effective treatment, especially in identifying acute coronary artery occlusions. The OMI-NOMI framework offers a more anatomically and physiologically accurate model, backed by a wealth of clinical research and expert opinion. It underscores the need for quick ECG assessments and immediate reperfusion therapies for suspected OMI cases, aiming to improve patient outcomes. The OMI-NOMI framework offers a new avenue for future research and clinical application. It advocates for a more comprehensive understanding of the underlying mechanisms of acute coronary syndromes, leading to individualized treatment plans. This novel approach is expected to ignite further scholarly debate and research, particularly in the Brazilian cardiology sector, with the goal of enhancing diagnostic accuracy and treatment effectiveness in AMI patients.

Embora o modelo existente de classificação do infarto agudo do miocárdio (IAM) em IAMCSST e IAMSSST tenha sido benéfico, considera-se hoje que ele falha em abordar a complexidade das síndromes coronarianas agudas. O estudo tem como objetivo examinar o atual paradigma IAMCSST-IAMSSST e defender um modelo mais detalhado, chamado de oclusão coronariana aguda (OCA) e Ausência de Oclusão Coronária Aguda (NOCA), para um diagnóstico e um manejo do IAM mais precisos. Realizou-se uma análise abrangente da literatura médica existente, com foco nas limitações do modelo IAMCSST-IAMSSST. O estudo também descreve uma nova abordagem diagnóstica para pacientes apresentando do torácica nos departamentos de emergência. O modelo IAMCSST-IAMSSST tradicional falha em prover um diagnóstico preciso e um tratamento efetivo, principalmente na identificação de oclusões da artéria coronária. O modelo OCA-NOCA é mais preciso em termos anatômicos e fisiológicos, e apoiado por pesquisa clínica extensa e opiniões de especialistas. Ele destaca a necessidade de rápida realização de eletrocardiogramas (ECGs) e terapias de reperfusão para casos suspeitos de OCA, visando melhorar os desfechos dos pacientes. O modelo OCA-NOCA abre um novo caminho para pesquisas e aplicações clínicas futuras. Ele defende um entendimento mais abrangente dos mecanismos subjacentes das síndromes coronarianas agudas, levando a planos individualizados de tratamentos. Espera-se que essa nova abordagem incite novos debates e pesquisas acadêmicas, principalmente na área de cardiologia no Brasil, com o objetivo de aumentar a precisão diagnóstica e a eficácia do tratamento de pacientes com IAM.

Childhood leprosy in Buenos Aires: four cases report. / Lepra infantil en Buenos Aires. Reporte de cuatro casos.

Childhood leprosy, which affects children up to 14 years old, is characterized by a delay in diagnosis since it is usually confused with other dermatoses. Its presence in a child is a relevant epidemiological indicator since it signals active disease transmission. We present 4 patients between 5 and 14 years old who attended a public hospital in Buenos Aires -two patients with borderline tuberculoid leprosy, one with lepromatous leprosy, and one with indeterminate leprosy.The World Health Organization provides therapy for people between 10 and 14 but does not consider children under 10. This difficulty implies adapting the dosage and pharmaceutical form to each patient under this age. Finally, it should be noted that the diagnosis of the patients led to the diagnosis and treatment of the disease in adult cohabitants.

La lepra infantil, aquella que afecta a niños de hasta 14 años, se caracteriza por la demora en su diagnóstico, ya que habitualmente es confundida con otras dermatosis. Su presencia en un niño es un indicador epidemiológico relevante, dado que señala la transmisión activa de la enfermedad. Presentamos 4 pacientes de entre 5 y 14 años asistidos en un hospital público de la Ciudad de Buenos Aires. Dos pacientes presentaron lepra borderline tuberculoide; uno, lepra lepromatosa; y otra, lepra indeterminada. La Organización Mundial de la Salud facilita la terapéutica para la población entre 10 y 14 años, pero no contempla a los menores de 10 años. Esta dificultad implica adecuar la dosis y la forma farmacéutica a cada paciente menor de la edad referida. Finalmente, es de destacar que el diagnóstico de los pacientes llevó al diagnóstico y tratamiento de la enfermedad en convivientes adultos.

Excision of a Solitary Fibrous Tumor in the Sciatic Notch with Sciatic Nerve Compression - A Rare Clinical Case.

We present the clinical case of a 41-year-old woman with no relevant personal history. The patient complained of diffuse self-limiting abdominal pain, and we incidentally detected an extra-abdominal, extraperitoneal tumor mass at the level of the right sciatic notch. The abdominal complaints were gone during the initial follow-up, but the patient developed sciatica radiating to the right foot and electric shock-like pain. A computed tomography (CT)-guided biopsy revealed a low-grade mesenchymal neoplasm of the soft tissues with characteristics consistent with a solitary extrapleural fibrous tumor. The pelvis team of the orthopedics department received the patient for surgical excision of the lesion. The procedure occurred with no complications, and we excised the totality of the lesion with tumor-free margins. An anatomopathological examination was compatible with the biopsy assessment. The excision of the lesion resulted in complete resolution of the sciatic nerve compression-related symptoms.

Femoral Head Reduction Osteotomy for Legg-Calvé-Perthes Disease Sequelae: Case Report.

Legg-Calvé-Perthes disease (LCPD) commonly causes sequelae in the hip joint morphology. A common variant is an oversized, nonspherical femoral head, associated with a short femoral neck and elevated greater trochanter, which leads to femoroacetabular impingement (FAI). The innovative Ganz technique for surgical hip dislocation opened up new treatment possibilities for FAI, including LCPD sequelae, without increasing the risk of avascular necrosis of the femoral head. In the ellipsoid coxa magna resulting from LCPD, joint wear is more accentuated in the central portion of the femoral head; the lateral third remains intact as it does not articulate with the acetabulum. A femoral head reduction osteotomy technique developed for such cases resects the damaged portion of the femoral head and restores its sphericity. Short-term outcomes are encouraging. The present case report presents a patient with LCPD sequelae submitted to a femoral head reduction osteotomy.

Contaminants of Emerging Concern (CECs): assessment of health and dietary risk in the consumption of Plagioscion squamosissimus in one of the largest rivers in a semi-arid region (Rio São Francisco, Brazil).

The São Francisco River, significant in semi-arid areas, faces impacts from hydroelectric plants and agricultural pesticides. Despite extensive research on its aquatic life, especially fish reproductive biology, there's a notable lack of studies on toxicity and its human health implications. This gap highlights the need for targeted research in this vital ecological zone. Consequently, this study aimed to scrutinize the concentrations of Contaminants of Emerging Concern (CECs), including Polychlorinated Biphenyls (PCBs), Polybrominated Diphenyl Ethers (PBDEs), Organochlorine Pesticides (OCPs), pyrethroid pesticides (PPs), triazine pesticides (TPs), and Organophosphorus Pesticides (OPPs) in the water, sediment, and fish (Plagioscion squamosissimus). The findings revealed the presence of all compound classes in sediment, albeit in limited quantities in water. Biotic components exhibited higher concentrations in nerve tissue, followed by the liver and muscle, indicative of a bioaccumulation trend. It is noteworthy that more concerning levels were observed in both water and sediments. In particular, Fenvalerate in water and Prometon in sediments demonstrated the highest Bioaccumulation Factor (BAF) values. While for non-carcinogenic effects and Cancer Risk (CR), the parameters were calculated and all classified in the areas of acceptable or insignificant according to chemical safety agencies. However, the compounds under scrutiny demand vigilant attention, given their nearly ubiquitous presence across various matrices and demonstrated bioaccumulative capacity, potentially posing future repercussions for human health.

Brain and serum lipidomic profiles implicate Lands cycle acyl chain remodeling association with APOEε4 and mild cognitive impairment.

Introduction: At least one-third of the identified risk alleles from Genome-Wide Association Studies (GWAS) of Alzheimer's disease (AD) are involved in lipid metabolism, lipid transport, or direct lipid binding. In fact, a common genetic variant (ε4) in a cholesterol and phospholipid transporter, Apolipoprotein E (APOEε4), is the primary genetic risk factor for late-onset AD. In addition to genetic variants, lipidomic studies have reported severe metabolic dysregulation in human autopsy brain tissue, cerebrospinal fluid, blood, and multiple mouse models of AD. Methods: We aimed to identify an overarching metabolic pathway in lipid metabolism by integrating analyses of lipidomics and transcriptomics from the Religious Order Study and Rush Memory Aging Project (ROSMAP) using differential analysis and network correlation analysis. Results: Coordinated differences in lipids were found to be dysregulated in association with both mild cognitive impairment (MCI) and APOEε4 carriers. Interestingly, these correlations were weakened when adjusting for education. Indeed, the cognitively non-impaired APOEε4 carriers have higher education levels in the ROSMAP cohort, suggesting that this lipid signature may be associated with a resilience phenotype. Network correlation analysis identified multiple differential lipids within a single module that are substrates and products in the Lands Cycle for acyl chain remodeling. In addition, our analyses identified multiple genes in the Lands Cycle acyl chain remodeling pathway, which were associated with cognitive decline independent of amyloid-ß (Aß) load and tau tangle pathologies. Discussion: Our studies highlight the critical differences in acyl chain remodeling in brain tissue from APOEε4 carriers and individual non-carriers with MCI. A coordinated lipid profile shift in dorsolateral prefrontal cortex from both APOEε4 carriers and MCI suggests differences in lipid metabolism occur early in disease stage and highlights lipid homeostasis as a tractable target for early disease modifying intervention.

Non-hemorrhagic imaging markers of cerebral amyloid angiopathy in memory clinic patients.

INTRODUCTION: The Boston criteria v2.0 for cerebral amyloid angiopathy (CAA) incorporated non-hemorrhagic imaging markers. Their prevalence and significance in patients with cognitive impairment remain uncertain. METHODS: We studied 622 memory clinic patients with available magnetic resonance imaging (MRI) and cerebrospinal fluid (CSF) biomarkers. Two raters assessed non-hemorrhagic markers, and we explored their association with clinical characteristics through multivariate analyses. RESULTS: Most patients had mild cognitive impairment; median age was 71 years and 50% were female. Using the v2.0 criteria, possible or probable CAA increased from 75 to 383 patients. Sixty-eight percent of the sample had non-hemorrhagic CAA markers, which were independently associated with age (odds ratio [OR] = 1.04, 95% confidence interval [CI] = 1.01-1.07), female sex (OR = 1.68, 95% CI = 1.11-2.54), and hemorrhagic CAA markers (OR = 2.11, 95% CI = 1.02-4.35). DISCUSSION: Two-thirds of patients from a memory clinic cohort had non-hemorrhagic CAA markers, increasing the number of patients meeting the v2.0 CAA criteria. Longitudinal approaches should explore the implications of these markers, particularly the hemorrhagic risk in this population. HIGHLIGHTS: The updated Boston criteria for cerebral amyloid angiopathy (CAA) now include non-hemorrhagic markers. The prevalence of non-hemorrhagic CAA markers in memory clinic patients is unknown. Two-thirds of patients in our memory clinic presented non-hemorrhagic CAA markers. The presence of these markers was associated with age, female sex, and hemorrhagic CAA markers. The hemorrhagic risk of patients presenting these type of markers remains unclear.

Correlation between Genomic Variants and Worldwide COVID-19 Epidemiology.

COVID-19 is a systemic disease caused by the etiologic agent SARS-CoV-2, first reported in Hubei Province in Wuhan, China, in late 2019. The SARS-CoV-2 virus has evolved over time with distinct transmissibility subvariants from ancestral lineages. The clinical manifestations of the disease vary according to their severity and can range from asymptomatic to severe. Due to the rapid evolution to a pandemic, epidemiological studies have become essential to understand and effectively combat COVID-19, as the incidence and mortality of this disease vary between territories and populations. This study correlated epidemiological data on the incidence and mortality of COVID-19 with frequencies of important SNPs in GWAS studies associated with the susceptibility and mortality of this disease in different populations. Our results indicated significant correlations for 11 genetic variants (rs117169628, rs2547438, rs2271616, rs12610495, rs12046291, rs35705950, rs2176724, rs10774671, rs1073165, rs4804803 and rs7528026). Of these 11 variants, 7 (rs12046291, rs117169628, rs1073165, rs2547438, rs2271616, rs12610495 and rs35705950) were positively correlated with the incidence rate, these variants were more frequent in EUR populations, suggesting that this population is more susceptible to COVID-19. The rs2176724 variant was inversely related to incidence rates; therefore, the higher the frequency of the allele is, the lower the incidence rate. This variant was more frequent in the AFR population, which suggests a protective factor against SARS-CoV-2 infection in this population. The variants rs10774671, rs4804803, and rs7528026 showed a significant relationship with mortality rates. SNPs rs10774671 and rs4804803 were inversely related to mortality rates and are more frequently present in the AFR population. The rs7528026 variant, which is more frequent in the AMR population, was positively related to mortality rates. The study has the potential to identify and correlate the genetic profile with epidemiological data, identify populations that are more susceptible to severe forms of COVID-19, and relate them to incidence and mortality.

Histological biomarkers and microbiological parameters of an estuarine fish from the Brazilian Amazon coast as potential indicators of risk to human health.

This study aimed to isolate and identify pathogenic bacteria in the intestinal tract, skin, and muscles of Sciades herzbergii; detect histopathological changes in the gill and liver; and use these biomarkers for the assessment of potential risks to human health. Fish were sampled during the rainy and dry seasons at two points in São Marcos Bay, Maranhão, Brazil: Ilha dos Caranguejos (IC) and Porto Grande (PG). Isolation and quantification were carried out using COLItest®. Colonies were subjected to identification and phenotypic investigation of antimicrobial resistance using Vitek®. Gill and liver samples were subjected to routine histological examination. The results indicated the presence of Klebsiella pneumoniae and Escherichia coli, the latter of which showed phenotypic resistance to norfloxacin and gentamicin. Fish caught at PG exhibited more extensive gill and liver damage than fish caught at IC. The findings suggest that histological changes in target organs of S. herzbergii may be influenced by infection with pathogenic bacteria.

Standardization use of the international classification of functioning, disability and health in the determination of health status in patients with post-acute COVID-19 syndrome.

PURPOSE: To propose a standardized method for the use of the International Classification of Functioning, Disability and Health (ICF) to describe the health status in Post-Acute COVID-19 Syndrome (PACS) and investigate interrater agreement in the linking process in instruments and clinical exams using the ICF categories. MATERIALS AND METHODS: Cross-sectional and interrater agreement study that followed the Guidelines for Reporting Reliability and Agreement Studies. Two raters performed the linking coding process in instruments of quality of life, anxiety and depression, fatigue and pulmonary function, inspiratory muscle strength and cardiopulmonary exercise testing. The codes were qualified by standards defined to each instrument and exams. RESULTS: The instrument with the lowest Cohen's Kappa coefficient was anxiety and depression (k = 0.57). Forty ICF codes were linked to clinical instruments and exams. The fatigue instrument presented a higher degree of disability by the qualification process, from severe to complete, in the linked codes. CONCLUSION: The study presents a standardized method for the assessment of the health status of patients with PACS through ICF. Restriction in work performance, socialization and family relationships as well as disabilities in physical endurance, fatigue and exercise tolerance were found in the sample. The agreement between the raters was moderate to perfect, demonstrating that the method can be reproducible.

The body structures and functions, environmental factors, activities and participation in a person's environment are determinant aspects of his health.Ways to measure these aspects are key to assessing health not only as absence of disease, so the International Classification of Disability and Functional Health demonstrates the ability to fully describe health.This study proposes a standardization in the use of the tool to facilitate usability in clinical practice.

Orange passion fruit (Passiflora caerulea L.) as a new raw material for acetic fermentation: evaluation of organic acids and phenolic profile, in vitro digestion, and biological activities.

BACKGROUND: This study evaluated for the first time the potential of orange passion fruit as a base for alcoholic and acetic fermentations, with a view to assessing its profile of organic acids and polyphenols, in vitro digestion, and biological activities. RESULTS: In terms of aliphatic organic acids, malic acid was the majority in the wine (3.19 g L-1), while in the vinegar, it was acetic acid (46.84 g L-1). 3,4-Dihydroxybenzoic acid (3,4-DHB) was the major phenolic compound in the wine and vinegar samples (3443.93 and 2980.00 µg L-1, respectively). After the in vitro gastrointestinal simulation stage, the wine showed high bioaccessibility for the compounds sinipaldehyde (82.97%) and 2,4-dihydroxybenzoic acid (2,4-DHBA, 81.27%), while the vinegar exhibited high bioaccessibility for sinipaldehyde (89.39%). Through multivariate analysis, it was observed that 3,4-DHB was highly concentrated in the different digested fractions obtained from the wine. In contrast, in the vinegar, the stability of isorahmenetin and Quercetin 3-o-rhamnoside was observed during the in vitro digestion simulation. Lastly, the vinegar stood out for its inhibition rates of α-amylase (23.93%), α-glucoside (18.34%), and angiotensin-converting enzyme (10.92%). In addition, the vinegar had an inhibitory effect on the pathogenic microorganisms Salmonella enteritidis, Escherichia coli, and Listeria monocytogenes. CONCLUSION: Orange passion fruit has proved to be a promising raw material for the development of fermented beverages. Therefore, this study provides an unprecedented perspective on the use and valorization of orange passion fruit, contributing significantly to the advancement of knowledge about fermented products and the associated nutritional and functional possibilities. © 2024 Society of Chemical Industry.

Investigating the correlation between genotype and phenotype in Prader-Willi syndrome: a study of 45 cases from Brazil.

BACKGROUND: Prader-Willi syndrome (PWS) is a genetic disorder characterized by abnormalities in the 15q11-q13 region. Understanding the correlation between genotype and phenotype in PWS is crucial for improved genetic counseling and prognosis. In this study, we aimed to investigate the correlation between genotype and phenotype in 45 PWS patients who previously underwent methylation-sensitive high-resolution melting (MS-HRM) for diagnosis. RESULTS: We employed methylation-specific multiplex ligation-dependent probe amplification (MS-MLPA) and Sanger sequencing, along with collecting phenotypic data from the patients for comparison. Among the 45 patients, 29 (64%) exhibited a deletion of 15q11-q13, while the remaining 16 (36%) had uniparental disomy. No statistically significant differences were found in the main signs and symptoms of PWS. However, three clinical features showed significant differences between the groups. Deletion patients had a higher prevalence of myopia than those with uniparental disomy, as well as obstructive sleep apnea and an unusual skill with puzzles. CONCLUSIONS: The diagnostic tests (MS-HRM, MS-MLPA, and Sanger sequencing) yielded positive results, supporting their applicability in PWS diagnosis. The study's findings indicate a general similarity in the genotype-phenotype correlation across genetic subtypes of PWS.
