RESUMO

BACKGROUND: Due to the lack of published literature about treatment of refractory hepatopulmonary syndrome (HPS) after liver transplant (LT), this case adds information and experience on this issue along with a treatment with positive outcomes. HPS is a complication of end-stage liver disease, with a 10%-30% incidence in cirrhotic patients. LT can reverse the physiopathology of this process and restore normal oxygenation. However, in some cases, refractory hypoxemia persists, and extracorporeal membrane oxygenation (ECMO) can be used as a rescue therapy with good results. CASE SUMMARY: A 59-year-old patient with alcohol-related liver cirrhosis and portal hypertension was included in the LT waiting list for HPS. He had good liver function (Model for End-Stage Liver Disease score 12, Child-Pugh class B7). He had pulmonary fibrosis and a mild restrictive respiratory pattern with a basal oxygen saturation of 82%. The macroaggregated albumin test result was > 30. Spirometry demon strated a forced expiratory volume in one second (FEV1) of 78%, forced vital capacity (FVC) of 74%, FEV1/FVC ratio of 81%, diffusion capacity for carbon monoxide of 42%, and carbon monoxide transfer coefficient of 57%. He required domiciliary oxygen at 2 L/min (16 h/d). The patient was admitted to the intensive care unit (ICU) and extubated in the first 24 h, needing high-flow therapy and non-invasive ventilation and inhaled nitric oxide afterwards. Reintubation was needed after 72 h. Due to the non-response to supportive therapies, installation of ECMO was decided with progressive recovery after 9 d. Extubation was possible on the tenth day, maintaining a high-flow nasal cannula and de-escalating to conventional oxygen therapy after 48 h. He was discharged from ICU on postoperative day (POD) 20 with a 90%-92% oxygen saturation. Steroid recycling was needed twice for acute rejection. The patient was discharged from hospital on POD 27 with no symptoms, with an 89%-90% oxygen saturation. CONCLUSION: Due to the favorable results observed, ECMO could become the central axis of treatment of HPS and refractory hypoxemia after LT.

RESUMO

Mucoepidermoid carcinomas (MECas) are malignant epithelial salivary gland neoplasms composed of a variable mixture of epidermoid and mucus-secreting cells arising from the ductal epithelium. Of all salivary gland tumors, MECas are the most common malignant lesions of the parotid gland. This case report aims to present a 14-year-old female patient with a history of progressive enlargement of a 3 cm in diameter, painless, mobile mass located at the parotid gland without facial nerve dysfunction. The lesion was exhaustively studied preoperatively, and studies were carried out. Contrast-enhanced computerized tomography (CECT) showed an increase in nodule numbers and size at the level of both the jugular and posterior cervical chains. In contrast, the gland's fine needle aspiration (FNA) showed a mucinous background. The histologic depiction established that the tumor was MECa of the parotid gland. The literature reviews on MECa encompass discussions about its prevalence, etiology, histological findings, and treatment.

RESUMO

The development of laparoscopic liver surgery, the improvement in the perioperative care programs, and the surgical innovation have allowed liver resections on selected cirrhotic patients. However, the great majority of ERAS studies for liver surgery have been conducted on patients with normal liver parenchyma, while its application on cirrhotic patients is limited. The purpose of this study was to evaluate the implementation of an ERAS protocol in cirrhotic patients who underwent liver surgery. We present an analytical observational prospective cohort study, which included all adult patients who underwent a liver resection between December 2017 and December 2019 with an ERAS program. We compare the outcomes in patients cirrhotic (CG)/non-cirrhotic (NCG). A total of 101 patients were included. Thirty of these (29.7%) were patients ≥ 70 cirrhotic. 87% of the both groups had performed > 70% of the ERAS. Oral diet tolerance and mobilization on the first postoperative day were similar in both groups. The hospital stay was similar in both groups (2.9 days/2.99 days). Morbidity and mortality were similar; Clavien I-II (CG: 44% vs NCG: 30%) and Clavien ≥ III (CG: 3% vs NCG: 8%). Hospital re-entry was higher in the NCG. Overall mortality of the study was 1%. ERAS protocol compliance was associated with a decrease in complications (ERAS < 70%: 80% vs ERAS > 90%: 20%; p: 0.02) and decrease in severity of complications in both study groups. The application of the ERAS program in cirrhotic patients who undergo liver surgery is feasible, safe, and reproducible. It allows postoperative complications, mortality, hospital stay, and readmission rates comparable to those in standard patients.

RESUMO

In 1992, Goodale and Milner proposed to study the visual system based on function, thus dissociating vision for perception (ventral stream) and vision for action (dorsal stream). This became known as the Perception and Action model (PAM). Following the PAM in the visual system, a somatosensory PAM was proposed including a body representation for perception and a separate for action. This review explores the body model of the hand and how it relates to the PAM. The body model refers to the internal representation of the body that is responsible for position sense. Previous research has shown that the representation of the hand features systematic distortions: an overestimation of hand width and an underestimation of finger length. These distortions have been reported using different paradigms, different body parts, and in various settings. Thus, body model distortions appear to be a characteristic of human body representation. If the body model of the hand is distorted, how can actions like reaching and grasping be accurate? We review evidence that body model distortions may in fact provide a functional benefit to our actions, that cortical maps in the somatosensory and motor cortices reflect these distortions, and that actions rely on a distorted body model. We argue that the body model is a product of both the ventral and dorsal somatosensory streams. Further, we suggest that the body model is an example of the inextricable link between the two streams.

RESUMO

NASA envisions a future where humans establish a thriving colony on the Moon by 2050. Plants will be essential for this endeavor, but little is known about their adaptation to extraterrestrial bodies. The capacity to grow plants in lunar regolith would represent a major step towards this goal by minimizing the reliance on resources transported from Earth. Recent studies reveal that Arabidopsis thaliana can germinate and grow on genuine lunar regolith as well as on lunar regolith simulant. However, plants arrest in vegetative development and activate a variety of stress response pathways, most notably the oxidative stress response. Telomeres are hotspots for oxidative damage in the genome and a marker of fitness in many organisms. Here we examine A. thaliana growth on a lunar regolith simulant and the impact of this resource on plant physiology and on telomere dynamics, telomerase enzyme activity and genome oxidation. We report that plants successfully set seed and generate a viable second plant generation if the lunar regolith simulant is pre-washed with an antioxidant cocktail. However, plants sustain a higher degree of genome oxidation and decreased biomass relative to conventional Earth soil cultivation. Moreover, telomerase activity substantially declines and telomeres shorten in plants grown in lunar regolith simulant, implying that genome integrity may not be sustainable over the long-term. Overcoming these challenges will be an important goal in ensuring success on the lunar frontier.

RESUMO

BACKGROUND: Rheumatic and musculoskeletal diseases (RMDs) are chronic diseases that may alternate between asymptomatic periods and flares. These conditions require complex treatments and close monitoring by rheumatologists to mitigate their effects and improve the patient's quality of life. Often, delays in outpatient consultations or the patient's difficulties in keeping appointments make such close follow-up challenging. For this reason, it is very important to have open communication between patients and health professionals. In this context, implementing telemonitoring in the field of rheumatology has great potential, as it can facilitate the close monitoring of patients with RMDs. The use of these tools helps patients self-manage certain aspects of their disease. This could result in fewer visits to emergency departments and consultations, as well as enable better therapeutic compliance and identification of issues that would otherwise go unnoticed. OBJECTIVE: The main objective of this study is to evaluate the implementation of a hybrid care model called the mixed attention model (MAM) in clinical practice and determine whether its implementation improves clinical outcomes compared to conventional follow-up. METHODS: This is a multicenter prospective observational study involving 360 patients with rheumatoid arthritis (RA) and spondylarthritis (SpA) from 5 Spanish hospitals. The patients will be followed up by the MAM protocol, which is a care model that incorporates a digital tool consisting of a mobile app that patients can use at home and professionals can review asynchronously to detect incidents and follow patients' clinical evolution between face-to-face visits. Another group of patients, whose follow-up will be conducted in accordance with a traditional face-to-face care model, will be assessed as the control group. Sociodemographic characteristics, treatments, laboratory parameters, assessment of tender and swollen joints, visual analog scale for pain, and electronic patient-reported outcome (ePRO) reports will be collected for all participants. In the MAM group, these items will be self-assessed via both the mobile app and during face-to-face visits with the rheumatologist, who will do the same for patients included in the traditional care model. The patients will be able to report any incidence related to their disease or treatment through the mobile app. RESULTS: Participant recruitment began in March 2024 and will continue until December 2024. The follow-up period will be extended by 12 months for all patients. Data collection and analysis are scheduled for completion in December 2025. CONCLUSIONS: This paper aims to provide a detailed description of the development and implementation of a digital solution, specifically an MAM. The goal is to achieve significant economic and psychosocial impact within our health care system by enhancing control over RMDs.

RESUMO

Nipah virus (NiV) has been recently ranked by the World Health Organization as being among the top eight emerging pathogens likely to cause major epidemics, whereas no therapeutics or vaccines have yet been approved. We report a method to deliver immunogenic epitopes from NiV through the targeting of the CD40 receptor of antigen-presenting cells by fusing a selected humanized anti-CD40 monoclonal antibody to the Nipah glycoprotein with conserved NiV fusion and nucleocapsid peptides. In the African green monkey model, CD40.NiV induces specific immunoglobulin A (IgA) and IgG as well as cross-neutralizing responses against circulating NiV strains and Hendra virus and T cell responses. Challenge experiments using a NiV-B strain demonstrate the high protective efficacy of the vaccine, with all vaccinated animals surviving and showing no significant clinical signs or virus replication, suggesting that the CD40.NiV vaccine conferred sterilizing immunity. Overall, results obtained with the CD40.NiV vaccine are highly promising in terms of the breadth and efficacy against NiV.

RESUMO

Electrodes with nanostructured surface have emerged as promising low-impedance neural interfaces that can avoid the charge-injection restrictions typically associated to microelectrodes. In this work, we propose a novel approximation, based on a two-step template assisted electrodeposition technique, to obtain flexible nanostructured electrodes coated with core-shell Ni-Au vertical nanowires. These nanowires benefit from biocompatibility of the Au shell exposed to the environment and the mechanical properties of Ni that allow for nanowires longer and more homogeneous in length than their only-Au counterparts. The nanostructured electrodes show impedance values, measured by electrochemical impedance spectroscopy (EIS), at least 9 times lower than those of flat reference electrodes. This ratio is in good accordance with the increased effective surface area determined both from SEM images and cyclic voltammetry measurements, evidencing that only Au is exposed to the medium. The observed EIS profile evolution of Ni-Au electrodes over 7 days were very close to those of Au electrodes and differently from Ni ones. Finally, the morphology, viability and neuronal differentiation of rat embryonic cortical cells cultured on Ni-Au NW electrodes were found to be similar to those on control (glass) substrates and Au NW electrodes, accompanied by a lower glial cell differentiation. This positive in-vitro neural cell behavior encourages further investigation to explore the tissue responses that the implantation of these nanostructured electrodes might elicit in healthy (damaged) neural tissues in vivo, with special emphasis on eventual tissue encapsulation.

RESUMO

OBJECTIVES: To evaluate the clinical performance of posterior restorations over wet and dry dentin with an etch-and-rinse adhesive after 36 months of clinical service. METHODS: Forty-five participants were recruited, each one had at least two posterior teeth that needed restoration. Ninety restorations were placed on Class I or Class II cavities. For the restoration protocol, a simplified etch-and-rinse adhesive (Adper Single Bond 2) was applied over wet (WD) or dry dentin (DD) and later restored with a bulk-fill composite (Filtek Bulk Fill) under rubber dam isolation. Each restoration was evaluated using the World Dental Federation (FDI) criteria after 6, 12, and 36 months of clinical service, regarding the following principal restoration characteristics: postoperative sensitivity, marginal discoloration, marginal adaptation, fracture of material and retention, and recurrence of caries. Kruskal Wallis analysis of variance rank (α = 0.05) and Kaplan-Meier survival analysis were used for statistical analysis. RESULTS: After 36 months of clinical evaluation, no significant difference between groups was observed in each FDI criterion (p > 0.05). Twenty restorations (WD=10, DD=10) showed minor marginal staining, and twenty-two restorations (WD=11, DD=11) presented small marginal adaptation defects (p > 0.05). Four restorations were lost (WD = 2, DD = 2) and the fracture rates (95% confidence interval) were 94.9% for each one, without significant difference between wet and dry dentin (p > 0.05). SIGNIFICANCE: The degree of dentin moisture does not seem to affect the clinical performance of a simplified etch-and-rinse adhesive in posterior restorations when the adhesive is applied vigorously over the dentine surface.

RESUMO

Introducción: Los pacientes en las unidades de cuidados intensivos son susceptible de presentar riesgo nutricional debido a las dificultades en adaptarse al medio extrauterino, enfermedades asociadas a la prematuridad, entre otros factores.Objetivo: Describir las características nutricionales de la población de pacientes hospitalizados en unidad neonatal de cuidados intensivos de un hospital universitario de alta complejidad.Métodos: Estudio descriptivo longitudinal de la cohorte de recién nacidos prematuros hospitalizados en la Unidad de Cuidados Intensivos Neonatal (UCIN), en un hospital de alta complejidad de Colombia. La clasificación nutricional se basó en medidas antropométricas a partir de la interpretación de curvas de Fenton y revisión de antecedentes perinatales.Resultados: 51 pacientes fueron estudiados, en su mayoría de sexo femenino y edad gestacional entre ≥28 y < 32 semanas (n=40, 78.43%), con una mediana de estancia hospitalaria de 41 días (IQR=12). A partir de la evaluación nutricional al ingreso, se identificó un peso para la edad gestacional adecuado (percentil ≥10 y < 90) en 88,24% de los neonatos, con implementación de nutrición parenteral para todos los pacientes, evolucionando hasta la vía oral como método de ingesta al egreso. La principal enfermedad digestiva identificada fue la enterocolitis necrosante y como otras enfermedades de interés, se resalta la infección severa y el síndrome de dificultad respiratoria.Conclusiones: A partir de la evaluación nutricional, se identificaron alteraciones nutricionales relacionadas con el peso para la edad gestacional y la velocidad de crecimiento en la UCIN que requieren de especial atención e intervención, por lo que se recomienda disponer de una evaluación y seguimiento nutricional sistemático en los pacientes desde el ingreso.(AU)


Introduction: Patients in intensive care units are likely topresent nutritional risk due to difficulties in adapting to theextrauterine environment, diseases associated with prematu-rity, among other factors.Objective: To describe the nutritional characteristics ofpatients hospitalized in the neonatal intensive care unit of ahigh complexity hospital. Methods: Longitudinal descriptive study. We analyze thecohort of premature newborns hospitalized in the NeonatalIntensive Care Unit (NICU), in a high complexity hospital Colombia. Nutritional classification was based on anthropo-metric measurements from the interpretation of Fentoncurves and review of perinatal history. Results: 51 patients were studied, mostly female and ges-tational age between ≥28 and <32 weeks (n=40, 78.43%),with a median length of stay of 41 days (IQR=12). From thenutritional evaluation at admission, an adequate weight forgestational age (percentile ≥10 and <90) was identified in88.24% of the neonates, with implementation of parenteralnutrition for all patients, evolving to the oral route as amethod of intake at discharge. The main digestive diseaseidentified was necrotizing enterocolitis and, like other dis-eases of interest, severe infection and respiratory distresssyndrome stand out. Conclusions: Based on the nutritional evaluation, nutri-tional alterations related to weight for gestational age andgrowth rate in the NICU were identified, which require specialattention and intervention, so it is recommended to have asystematic nutritional evaluation and follow-up in patientsfrom admission.(AU)

RESUMO

Objetivo: Estimar la efectividad de los programas de prevención de caídas en mayores de 65 años en los que participan profesionales de enfermería. Métodos: Se incluyeron ensayos clínicos aleatorizados disponibles a texto completo sobre la prevención de caídas en la comunidad realizada por enfermeras en personas mayores de 65 años y que informaran de la incidencia de dichas caídas. Se analizaron 14 bases de datos en el período de 2016 a 2018 de publicaciones en inglés, francés, portugués y español. La calidad de los artículos se evaluó de manera independiente y ciega por los revisores, que trabajaron en parejas usando para ello los dominios de riesgo de riesgo de la Colaboración Cochrane. Se utilizó el cociente de riesgos como medida del tamaño de efecto. Se asumió un modelo de efectos aleatorios para los análisis estadísticos. La influencia de las variables moderadoras de los estudios sobre los tamaños de efecto se realizó mediante ANOVA con un intervalo de confianza del 95% para cada categoría. Resultados: Se seleccionaron 31 estudios con 25.551 participantes, donde la intervención más frecuente fue la educación (57,1%), seguida de los modelos multifactoriales (37,1%). La probabilidad de caídas se redujo significativamente en los grupos intervención (RR +=0,87). Las intervenciones multifactoriales (RR +=0,89) y basadas en la educación (RR=+0,84) redujeron significativamente la probabilidad de caídas. Conclusiones: Descartando el sesgo de publicación, los programas de prevención llevados a cabo por enfermeras producen una reducción significativa del 10% de las caídas. Las intervenciones basadas en la educación y multifactoriales son las más efectivas cuando son llevadas a cabo por enfermeras.(AU)


Objective: To estimate the effectiveness of fall prevention programs in people aged 65 years and older involving nursing professionals. Methods: We included available full-text randomized clinical trials on nurse-led prevention of falls in the community in people over 65 years of age and reporting the incidence of such falls. An extensive search was performed in 14 databases covering the period 2016 to 2018 for publications in English, French, Portuguese and Spanish. The quality of the papers was assessed independently and blindly by reviewers working in pairs using the risk of bias dominios of the Cochrane Collaboration. The hazard ratio was used as a measure of the effect size of the incidence of falls. A random-effects model was assumed for statistical analyses. The influence of moderator variables of the studies on the effect sizes was performed using ANOVAs and its 95% CI for each moderator category. Results: A total of 31 randomized clinical trials were selected with 25,551 participants. The most frequent type of intervention was education (57.1%), followed by multifactorial models (37.1%). The probability of falling was significantly reduced by 13% in the intervention groups compared to the control groups (RR +=0.87). Multifactorial (RR +=0.89) and education-based (RR=+0.84) interventions significantly reduced the probability of falls by 11% and 16%, respectively. Conclusions: Discarding publication bias prevention programs carried out by nurses produce a significant 10% reduction in falls. Education-based and multifactorial interventions are the most effective when conducted by nurses.(AU)

RESUMO

This study explores the phytochemical composition of leaf extracts from Handroanthus impetiginosus (Mart.) Mattos and Luehea divaricata Mart., used in a contraceptive decoction by Mbya-Guarani women. The phytocompounds were identified by gas chro-matography-mass spectrometry, while Fourier-transform infrared spectroscopy, multi-elemental, and thermal analyses were used to characterise plant biomass. Notably, no phytoconstituent supporting the efficacy of these extracts as female contraceptives was found, except for a small amount (0.3%) of sitosterol. Conversely, L. divaricata leaves contained compounds like 1,3-dihydroxyacetone dimer, N-methyl-N-nitroso-2-propanamine, 2-methoxy-N-(2-methoxyethyl)-N-methyl-ethanamine, and 1,3,5-triazine-2,4,6-triamine, potentially exerting cytotoxic, genotoxic, and toxicogenomic effects. Due to the absence of scientific support for the claimed contraceptive efficacy and the presence of safety concerns, we propose an alternative valorisation pathway centred on the presence of phytochemicals exhibiting antimicrobial activity. This proposition is substantiated by their considerable in vitro efficacy against Botrytis cinerea.

RESUMO

Sarcopenia, a complex and debilitating condition characterized by progressive deterioration of skeletal muscle, is the primary cause of age-associated disability and significantly impacts healthspan in elderly patients. Despite its prevalence among the aging population, the underlying molecular mechanisms are still under investigation. The NLRP3 inflammasome is crucial in the innate immune response and has a significant impact on diseases related to inflammation and aging. Here, we investigated the expression of the NLRP3 inflammasome pathway and pro-inflammatory cytokines in skeletal muscle and peripheral blood of dependent and independent patients who underwent hip surgery. Patients were categorized into independent and dependent individuals based on their Barthel Index. The expression of NLRP3 inflammasome components was significantly upregulated in sarcopenic muscle from dependent patients, accompanied by higher levels of Caspase-1, IL-1ß and IL-6. Among older dependent individuals with sarcopenia, there was a significant increase in the MYH3/MYH2 ratio, indicating a transcriptional shift in expression from mature to developmental myosin isoforms. Creatine kinase levels and senescence markers were also higher in dependent patients, altogether resembling dystrophic diseases and indicating muscle degeneration. In summary, we present evidence for the involvement of the NLRP3/ASC/NEK7/Caspase-1 inflammasome pathway with activation of pro-inflammatory SASP in the outcome of sarcopenia in the elderly.

RESUMO

Antimicrobial resistance in Neisseria gonorrhoeae (NG) is increasing worldwide. Second-line treatments with macrolides or fluoroquinolones are an option for NG infections in some cases following the STI guideline recommendations. In our study, we compared the gradient diffusion test using EUCAST 2024 breakpoints with a new molecular method using the Allplex™ NG&DR assay (Seegene®) including A2059G/C2611 mutations (23S rRNA) associated with high/moderate-level macrolide resistance and S91F mutation (gyrA) relationship with fluoroquinolone resistance in NG isolates (n = 100). We calculated the sensitivity, specificity, and correlation of the molecular test for fluoroquinolone using the gradient diffusion as the reference method. In twenty-three strains was not detected any mutation associated with macrolides or fluoroquinolone resistance. No A2059G/C2611T mutations were detected, and the S91F mutations were detected in 77 out of the 100 isolates screened. Twenty-three NG isolates were reported to be resistant to azithromycin (ECOFF: >1 mg/L), and 78 NG isolates were resistant to ciprofloxacin (MIC: >0.06 mg/L). The molecular method showed a sensitivity of 96.1% and, a specificity of 90.9% for fluoroquinolone susceptibility, but the statistical analysis between the molecular test and gradient diffusion test was not statistically significant for fluoroquinolone resistance (p = 1). Statistical analysis was not performed for macrolides because of the absence of positive RT-PCR results. According to our data, Allplex™ assay cannot replace the gradient diffusion test for macrolide resistance. However, the assay could be used to test fluoroquinolone resistance in NG isolates as a replacement for phenotypic methods.

RESUMO

Recent advances in the field of immuno-oncology have brought transformative changes in the management of cancer patients. The immune profile of tumours has been found to have key value in predicting disease prognosis and treatment response in various cancers. Multiplex immunohistochemistry and immunofluorescence have emerged as potent tools for the simultaneous detection of multiple protein biomarkers in a single tissue section, thereby expanding opportunities for molecular and immune profiling while preserving tissue samples. By establishing the phenotype of individual tumour cells when distributed within a mixed cell population, the identification of clinically relevant biomarkers with high-throughput multiplex immunophenotyping of tumour samples has great potential to guide appropriate treatment choices. Moreover, the emergence of novel multi-marker imaging approaches can now provide unprecedented insights into the tumour microenvironment, including the potential interplay between various cell types. However, there are significant challenges to widespread integration of these technologies in daily research and clinical practice. This review addresses the challenges and potential solutions within a structured framework of action from a regulatory and clinical trial perspective. New developments within the field of immunophenotyping using multiplexed tissue imaging platforms and associated digital pathology are also described, with a specific focus on translational implications across different subtypes of cancer. © 2024 The Authors.

RESUMO

Dermatologic ultrasound has grown exponentially during the last decades and has passed from the experimental phase to the routine daily practice in multiple countries. The performance of this imaging technique requires color Doppler ultrasound devices working with high-frequency probes, a trained operator on imaging and dermatologic conditions, and the performance of standardized protocols for obtaining the anatomical data properly. In this review, we analyze the ultrasonographic anatomy of the skin, hair, and nails, the technical requirements and considerations, the guidelines, and the recommended protocols, and provide the best tips for practicing this type of examination confidently.

RESUMO

Researchers have long observed distinct brain activity patterns in older adults compared with younger adults that correlate with cognitive performance. Mainly, older adults tend to show over-recruitment of bilateral brain regions during lower task loads and improved performance interpreted as compensation, but not observed at higher loads. However, there are discrepancies about whether increases in activity are compensatory and whether older adults can show compensation at higher loads. Our aim was to examine age-related differences in prefrontal cortex (PFC) activity and cognitive performance using functional near-infrared spectroscopy (fNIRS) during single and dual N-back tasks. Twenty-seven young adults (18-27 years) and 31 older adults (64-84 yrs) took part in the study. We used a robust fNIRS data methodology consisting of channel and region of interest analyses. Results showed differences in performance between task load conditions and age-related differences in reaction times but no age-group effects for accuracy. Older adults exhibited more bilateral PFC activation compared with young adults across all tasks and showed increases in brain activity in high compared to low load conditions. Our findings further support previous reports showing that older adults use compensatory recruitment of additional brain regions in PFC to maintain cognitive performance but go against the notion that such compensation is not present at higher cognitive loads. Additionally, our results indicate that fNIRS is a sensitive tool that can characterize adaptive cortical changes in healthy aging.

RESUMO

Background. The prevalence of drug-resistant Neisseria gonorrhoeae (NG) infections is increasing. Studies report the prevalence of NG strains presenting A2059G/C2611T (rRNA 23S) and S91F (parC) mutations conferring resistance to azith romycin and ciprofloxacin. Material and methods. We conducted a prospective cohort study evaluating first void-urine urines, rectal, and oropharyngeal swabs collected from a cohort of patients in a tertiary hospital in Madrid between October 2022 and January 2023. Samples were screened by Allplex™ 7-STI Essential As say (Seegene®). Drug resistances were performed by Allplex™ NG&DR Assay (Seegene®). Results. A total of 1,415 patients were included, of which 112 had a positive sample for NG infection. One patient had a C2611T mutation (0.9%) and neither patient showed A2059G mutation. We found 67 (59.8%) S91F-positive patients. For ty-four patients (39.3%) not had any mutations. Conclusions. We report a low-prevalence of mutations A2059G/C2611T to macrolides and a high-prevalence to S91F in NG infections. Molecular methods for the detection of NG resistance could be useful in direct non-culturable samples (AU)


Introducción. La infección por Neisseria gonorrhoeae (NG) resistente está aumentando. Se ha descrito la prevalencia de cepas de NG con mutaciones A2059G/C2611T (rRNA 23S) y S91F (parC) que confieren resistencia a azitromicina y cipro floxacino. Material y métodos. Realizamos un estudio prospecti vo evaluando orinas de primera micción, hisopos anales y fa ríngeos recogidos de una cohorte de pacientes en un hospital terciario de Madrid entre octubre de 2022 y enero de 2023. El cribado de las muestras se realizó mediante Allplex™ 7-STI Es sential Assay (Seegene®). Las resistencias a macrólidos y fluo roquinolonas se realizaron mediante Allplex™ NG&DR Assay (Seegene®). Resultados. Se incluyeron 1.415 pacientes, de los cua les 112 fueron positivos para NG. Un paciente presentaba una mutación C2611T (0,9%) y en ningún paciente se detec tó A2059G. Encontramos 67 pacientes (59,8%) positivos pa ra S91F. Cuarenta y cuatro pacientes (39,3%) no presentaban mutaciones. Conclusiones. Reportamos una baja prevalencia de mu taciones A2059G/C2611T a macrólidos y una alta prevalencia de S91F en NG. Los métodos moleculares para la detección de resistencias en NG podrían ser útiles en muestras directas no cultivables (AU)

RESUMO

The aim of the study was to describe and analyze the experience of people with advanced chronic kidney disease. Chronic kidney disease is a growing public health problem that is on the increase worldwideThe experience of living with this illness is paradoxical, as it can include feelings of dependent autonomy, distant connection, abnormal normalcy, and uncertain hope. Every chronic disease involves a biographical alteration from the onset. For those who suffer it, it implies a breaking down and reconstruction of their everyday life. Despite the prevalence of the disease and the increase in the number of qualitative research studies in recent decades, there has not been much research on the experience of people with Chronic kidney disease. This is a qualitative study that began in 2018 and concluded in 2021.Twenty-one people with advanced chronic kidney disease were interviewed. They participated voluntarily with informed consent Participants were selected by purposive sampling. Data analysis was guided by grounded theory procedures using the Nvivo 12 software. This study reveals that people with advanced chronic kidney disease do not feel the same as they used to because their control over their lives is limited; because they feel their health is in a continuous state of deterioration; and because of the changes in themselves and in their relationships with others. With chronic kidney disease, their identity is continually called into question. The normal lives of these people-their biographical constructions-are precarious and are continuously being remodelled by the effects of treatment and the inexorable course of this disease. This study contributes to an understanding of the experience of people with advanced chronic kidney disease. It can contribute to helping health care professionals effectively support these patients in their efforts to lead a normal life and in making decisions about their treatment.
