RESUMEN
Aging is one of the risk factors involved in the development of erectile dysfunction (ED). Growing evidence suggests that oxidative stress is the critical mediator of changes in endothelial function and penile vascular tone in the aging process. Thus, reducing reactive oxygen species (ROS) levels may preserve the bioactivity of the penile vasculature. Antioxidant compounds, such as carvacrol, limit the damage caused by ROS and, therefore, benefit the treatment of ED. Thus, this study aims to evaluate the effects of carvacrol on ED using the D-( +)-galactose aging model. The animals were divided into five groups: control, D-( +)-galactose 150 mg/kg, carvacrol 50 mg/kg or 100 mg/kg, and sildenafil 1.5 mg/kg treated daily for 8 weeks. The physiological, functional, and morphological characteristics of aging-associated ED were evaluated after treatment with carvacrol. Carvacrol prevented ED in a D-( +)-galactose-induced aging model by reducing hypercontractility, enhancing endothelial dysfunction in the rat corpus cavernosum, and improving endothelial health of rat cavernous endothelial cells. In addition, carvacrol prevented the destruction of erectile components essential for penile erection and promoted a reduction of penile tissue senescence, probably through mechanisms that involve the harmful modulation of oxidative stress. Carvacrol significantly improved the erectile function of rats in a D-( +)-galactose-induced aging model and has excellent potential as a new therapeutic alternative in treating erectile dysfunction.
RESUMEN
BACKGROUND: Successful use of carbapenems in combination with cefazolin or oxacillin for treatment of MSSA bacteraemia has been described; however, comparative data to standard treatment approaches are lacking. METHODS: This was a multicentre, retrospective study of adult patients with MSSA bacteraemia for >48 h. Standard treatment was considered monotherapy with cefazolin, oxacillin or nafcillin. Combination therapy was defined as the addition of ertapenem or meropenem to standard treatment for at least 24 h. The primary outcome was duration of bacteraemia defined as time from administration of an antibiotic with in vitro activity to first negative blood culture. Time to blood culture sterilization was compared through risk-set matching with aid of a propensity score. RESULTS: Overall, 238 patients were included; 66% (157/238) received standard treatment and 34% (81/238) received combination therapy. The median (IQR) time to carbapenem initiation was 4.7 (3.63-6.5) days. Patients who received combination therapy were younger (Pâ=â0.012), more likely to have endocarditis (Pâ=â0.034) and had longer median duration of bacteraemia (Pâ<â0.001). After applying risk-set matching, patients who received combination therapy experienced faster time to blood culture sterilization compared with control patients [HRâ=â1.618 (95% CI; 1.119-2.339) Pâ=â0.011]. Using a paired hazard model, 90 day mortality rates were not statistically different among patients who received combination therapy versus matched controls [HRâ=â1.267 (95% CI; 0.610-2.678), Pâ=â0.608]. DISCUSSION: Carbapenem combination therapy resulted in faster time to blood culture sterilization, but no differences in overall mortality rates. Randomized trials are critical to determine the utility of carbapenem combination therapy.

Introduction: The World Health Organization (WHO) has proposed to monitor intrinsic capacity (IC) in the older population as a public health strategy through the Integrated Care for Older People (ICOPE) program. Although the program has been developed based on solid concepts, scientific evidence on its practical applicability is still scarce. Objectives: To evaluate IC in Brazilian older adults, its progress over time, and its association with sociodemographic and health factors and outcomes. To evaluate the psychometric properties of the WHO/ICOPE screening tool. Methods: This is a prospective multicenter cohort study with a 36-month follow-up. We will recruit 3838 people aged ≥60 years, registered in the health care units included in the study by the participating centers. We will collect sociodemographic and health data and will administer tools to assess IC domains, both those provided for in the ICOPE screening tool and the sequence of confirmatory assessments provided for in the program. Participants will be reassessed every 6 months for 36 months. Expected results: To establish the profile of IC in the study population and to understand its progress and the variables associated with the clinical outcomes of interest. To reveal the diagnostic and psychometric properties of the WHO/ICOPE screening tool. The project is funded by the Brazilian National Council for Scientific and Technological Development (CNPq). Relevance: Understanding the potential use of the ICOPE public health strategy proposed by the WHO within the scope of the Brazilian Unified Health System (SUS) by integrating several research centers in the field of Geriatrics and Gerontology throughout Brazil.

PURPOSE: Monitoring intrinsic capacity (IC) in community-dwelling older people can be potentially used to alert for adverse health outcomes. However, whether there is an association between IC and hospitalization has yet to be fully explored. This study aimed to investigate the association of the IC composite measure and its 5 domains with hospitalization in the previous year and length of hospital stay. METHODS: We conducted cross-sectional analyses using data from a representative sample of community-dwelling adults (≥ 65 years). We assessed the IC domains (vitality, locomotor, cognitive, sensory, and psychological) using validated self-reported information and performance tests. We calculated standardized estimated scores (z scores) for IC composite measure and domains and conducted multivariate logistic and ordinal regressions. The primary outcomes were hospitalizations in the previous year and length of hospital stay. RESULTS: In a sample of 5354 participants (mean age = 73 ± 6 years), we found that participants with high IC composite z scores were less likely to have experienced hospitalization in the previous year (OR = 0.51; 95% CI = 0.44-0.58). Among those who were hospitalized, high IC scores were associated with short stays (OR = 0.87; 95% CI = 0.80-0.95). Cognitive and psychological domains were associated with hospitalizations, and the locomotor domain was related to length of hospital stay. The vitality domain was associated with both outcomes. CONCLUSION: IC as a composite measure was associated with previous hospitalizations and length of stay. IC can help clinicians identify older people prone to adverse outcomes, prompting preventive integrated care interventions.

OBJECTIVE: To describe the peculiarities in imaging acquisition of fourteen patients with choroidal nevus using the Broad Line Fundus Imaging (BLFI) technology. METHODS: Single-center, retrospective, cross-sectional analysis. RESULTS: All images were acquired using the BLFI technology. We have found that choroidal nevus is undetectable in the blue channel (BC) (435-500â nm) and the green channel (GC) (500-585â nm). The only visible changes are related to the drusen, which appeared in BC and GC as light focal dots, correlated to the yellowish foci in the true-color image. On the red channel (RC) (585-640â nm), all lesions revealed the same pattern: a well-defined dark spot, with enhanced contrast, allowing the better visualization, measuring, and characterization of the nevus when compared with the other color channels, including the true-color imaging. CONCLUSION: BLFI application in choroidal nevus might be helpful at presentation, refining the diagnostic reliability, and monitoring, as it allows for better detection of alterations in the lesions. The peculiarities of the choroidal nevus are better assessed when using the RC due to its longer wavelength and deeper penetration in the retina and choroid.
RESUMEN
BACKGROUND: The performance of staging systems in non-head and neck cutaneous squamous cell carcinomas has not been well established. OBJECTIVE: To evaluate the performance of the American Joint Committee on Cancer 8th Edition and Brigham and Women's Hospital staging systems in non-head and neck squamous cell carcinomas. MATERIALS AND METHODS: Eligible tumors were identified and staged from an existing retrospective database. Cumulative incidence function curves of any poor outcome were generated. Distinctiveness, sensitivity, specificity, positive and negative predictive value, and concordance index were calculated. RESULTS: 1,042 primary tumors were included, with 38 resulting in any poor outcome and 16 in any major poor outcome. High-stage tumors represented 2.2% and 3.5% of tumors; these accounted for 10/38 of the poor outcomes (26.3%) and 8/16 of the major poor outcomes (50%). High-stage tumors predicted major poor outcomes with a sensitivity of 0.5 and specificity of 0.99 for the Brigham and Women's Hospital system, and a sensitivity of 0.5 and specificity of 0.97 for the American Joint Committee on Cancer 8th edition system. The concordance index for both was 0.74. CONCLUSION: Current staging systems can be used to predict poor outcomes in cutaneous squamous cell carcinomas off the head and neck.

PURPOSE: To analyze the associations between pain and physical performance in different aging contexts. METHODS: Data from 1725 older adults from Canada, Brazil, Colombia, and Albania from the 2014 wave of the IMIAS were used to assess the associations between Back Pain (BP) or Lower Limb Pain (LLP) and physical performance by the Short Physical Performance Battery (SPPB). Three binary logistic regression models adjusted for sex, age, study site, education, income sufficiency, BMI, depressive symptoms, and chronic conditions were used to estimate the associations between LLP or BP and SPPB. The SPPB was classified into good performance (8 points or more) and poor physical performance (< 8 points). RESULTS: The mean age of the older men was 71.2 (± 3.0) and the mean age of the women was 71.2 (± 2.8) years. Older men (72.8%, p < 0.05) and women (86.1%, p-value < 0.05) from Albania had the highest frequencies of self-reported general pain. Older women in Colombia had the highest frequencies of LLP or BP (33.5%, p-value < 0.05). In the fully adjusted logistic regression model, LLP or BP was significantly associated with poor SPPB (OR = 0.48, 0.35 to 0.66 95% CI, p < 0.01). CONCLUSIONS: Pain symptoms are associated with reduced physical performance in older people, even when adjusted for other clinical and sociodemographic factors. Protocols for aiming to increase the level of physical activity to manage pain should be incorporated into health care strategies.

Myelodysplastic syndromes (MDS) are a group of clonal hematopoietic neoplasms resulting from mutations in stem cells. They carry a risk of transformation to acute myeloid leukemia. Cutaneous manifestations of MDS, including myelodysplasia cutis or infiltration by MDS tumor cells, are rare, but significantly associated with increased risk of progression to high-grade myeloid tumors. The clinical and histopathologic differential diagnosis for myelodysplasia cutis includes interstitial granulomatous dermatitis (IGD), a reactive granulomatous dermatitis (RGD) associated with systemic diseases including rheumatologic diseases, and hematologic malignancy like MDS. We report a patient with MDS who presented with myelodysplasia cutis masquerading as IGD both in a clinical and histopathological manner.

ABSTRACT Purpose: This study aimed to assess and interpret how vitreoretinal surgeons use surgical videos available on social media as complementary learning tools to improve, review, or update their abilities, considering their different levels of expertise. Methods: In this cross-sectional survey, an online survey was sent to vitreoretinal specialists and fellows. Results: This survey included 258 participants, of whom 53.88% had been in practice for >10 years (senior surgeons), 29.07% between 4 and 10 years (young surgeons), and 17.05% for <3 years (surgeons in training). Retinal surgical videos available on social media were used by 98.84% of the participants (95% confidence interval, 97.52%-100%). YouTube (91%) was the most common source of videos, and surgeons in training watched more videos on YouTube than senior surgeons. Regarding the preferred method when preparing for a procedure, 49.80% of the participants watched surgical videos available on social media, 26.27% preferred to "consult colleagues", and 18.82% preferred to seek information in scientific articles. Participants valued the most the "image quality" (88%) and presence of "surgical tips and tricks" (85%). Conclusion: Surgical videos can provide benefits in acquiring strategic skills, such as decision-making, surgical planning, and situational awareness. Retina surgeons used them as teaching aids regardless of their level of expertise, despite being relatively more valuable to surgeons in training or young surgeons.
RESUMO Objetivo: Avaliar e interpretar como os cirurgiões vitreorretinianos utilizam os vídeos cirúrgicos disponíveis nas mídias sociais como ferramentas complementares de aprendizagem para melhorar, revisar ou atualizar suas habilidades, considerando seus diferentes níveis de especialização. Métodos: Nesta pesquisa transversal, um survey online foi enviado à especialistas e aprendizes na área vítreo-retiniana. Resultados: Esta pesquisa incluiu 258 participantes, dos quais 53,88% atuavam há mais de 10 anos (cirurgiões seniores), 29,07% entre 4 e 10 anos (cirurgiões jovens) e 17,05% há menos de 3 anos (cirurgiões em treinamento). Vídeos cirúrgicos de retina nas mídias sociais foram usados por 98,84% dos participantes (intervalo de confiança de 95%, 97,52%-100%). A fonte mais comum de acesso aos vídeos foi o YouTube (91%), e o grupo de cirurgiões com menos de 3 anos de experiência assistiu mais vídeos no YouTube em comparação aos cirurgiões seniores. Assistir a vídeos cirúrgicos nas redes sociais foi o método preferido na preparação para um procedimento para 49,80% dos participantes versus 26,27% que preferiram "consultar colegas" e 18,82% que preferiram buscar informações em artigos científicos. A "qualidade de imagem" (88%) e a presença de "dicas e truques cirúrgicos" (85%) foram as características dos vídeos mais valorizadas pelos participantes. Conclusão: O uso de vídeos cirúrgicos pode trazer benefícios na aquisição de habilidades estratégicas, como tomada de decisão, planejamento cirúrgico e consciência situacional. Sua aplicação como auxiliar de ensino foi utilizada por cirurgiões de retina independentemente de seu nível de especialização, apesar de ser relativamente mais valioso para cirurgiões em formação ou com menos de 10 anos de experiência.
RESUMEN
PURPOSE: To assess telementoring as a complementary tool for surgical training of a scleral fixation technique. DESIGN: Randomized, controlled, two-arm, blinded clinical trial. METHODS: Using a 3D visualization system, 132 participants were randomized in order of enrollment into traditional face-to-face mentoring (n = 66) and telementoring (n = 66). A single surgeon mentored all participants in the 2 groups. The procedure was performed in a model suitable for training in intraocular lens fixation SimulEYE® (INSEYET, WESTLAKE VILLAGE, CA, USA). In the telementoring group, the images captured on a local computer were sent to a second computer located in another room through a teleconferencing platform in real-time. Nine steps of the recorded procedure were evaluated and scored by two masked independent surgeons experienced in the technique. MAIN OUTCOMES MEASURES: The primary outcomes evaluated were the global score (the sum of each score on the rubric), surgical failure, and surgical time (in seconds). RESULTS: Surgical success was achieved in 98.5% in the face-to-face group and in 95.5% in the telementoring group (p-value = 0.619). Minimal technical problems were reported in 8 procedures in the telementoring group (12%), without interfering with the surgical result, and completion of the procedure. CONCLUSIONS: Telementoring is an encouraging educational tool that can overcome geographical barriers to ease the transfer of abilities and knowledge. We lack evidence in terms of group differences for superiority comparing face-to-face and telementoring, in addition to presenting comparable results regarding surgical success and failure. More studies are needed to explore the impact of telementoring in other ophthalmological surgeries. TRIAL REGISTRATION: The Federal University of São Paulo institution's Research Ethics Committee reviewed and approved this study protocol (approval number, 5.383.484).

This study aimed to evaluate the effect of increasing levels of red propolis extract (RPE) in the diet of confined sheep on performance and histomorphometric parameters of rumen and intestine and histopathological parameters of liver and kidney. Thirty-five male sheep (17.08 ± 2.36 kg) were used, distributed in a completely randomized design, with five treatments (0, 7, 14, 21, and 28 mL day-1 RPE) and seven replications, submitted to 68 days of experiment. At the end of the experimental period, the animals were euthanized, and samples of rumen, intestine, liver, and kidney were collected to histomorphometry and histopathology analyzes. Higher RPE inclusions (21 and 28 mL day-1) maintained dry matter intake and increased total weight (5.78 x 6.14 and 6.95 kg, respectively) gain up to 20.24%. In the rumen, the inclusion of RPE led to an increase in the thickness of the epithelium and the highest level also increased the thickness of the keratinized portion of this epithelium (21.71 x 32.15 µm). The level of 21 mL day-1 provided larger ruminal papillae (1620.68 x 1641.70 µm) and greater ruminal absorption area (561791.43 x 698288.50 µm2). In intestine 21 and 28 mL-1 of RPE provided greater mucosal thickness (468.54 x 556.20 and 534.64 µm), higher goblet cell index (23.32 x 25.82 and 25.64) and higher hepatic glycogen index (1.47 x 1.64 and 1.62), supporting higher nutrients absortion and glicogenolise and intestinal health, corroborating the weight gain indices. The inclusion of RPE did not cause renal histopathological lesions. Therefore, levels of 21 and 28 mL day-1 of RPE can be used in sheep diets, promoting greater final weight gain, causing positive histomorphological changes in the rumen, intestine and liver, without causing kidney or liver damage.

Sulfur amino acids are essential for the proper development of broilers and are required throughout the bird's life to perform important physiological functions. Studies that seek to understand the actions of sulfur amino acids in the body of birds are essential. The present study evaluated the influence of sulfur amino acid supplementation using DL-Methionine (DL-Met) and DL-Methionine hydroxy analogue (DL-HMTBA), on the performance and expression of genes related to methionine metabolism, in the jejunum of broilers. Four hundred and fifty male broilers (Cobb-700 slow feathering) were distributed in a completely randomized design, in a factorial scheme (2x3), with two sources of methionine (DL-Met and DL-HMTBA) and three levels of methionine (deficiency, requirement and excess). The mRNA expression of the MAT1, MTR, BHMT, MTRR, CBG and GSS genes, and performance data such as feed intake, weight gain, and feed conversion were evaluated. DL-HMTBA increased the expression of BHMT (p = 0.0072) and MTRR (p = 0.0003) in the jejunum of the birds. Methionine deficiency increased the expression of BHMT (p = 0.0805) and MTRR (p = 0.0018). Higher expression of GSS was observed in birds that were supplemented with DL-HMTBA (p = 0.0672). Analyzing our results, it is preferable to supplement sulfur amino acids with DL-Met at the requirement level. Birds fed with DL-HMTBA showed worse weight gain (p = 0.0117) and higher feed conversion (p = 0.0170); methionine deficiency resulted in higher feed intake (p = 0.0214), lower weight gain (p<0.0001) and consequently higher feed conversion (p<0.0001). Based on the information found in this work, it is recommended to supplement sulfur amino acids with DL-Met at the level of compliance with the requirement.

Feedlot finishing of goats is a growing practice, but the economic viability of this technology is compromised by the inclusion of ingredients such as corn and soybean. An alternative to minimize this barrier is the use of agroindustry coproducts as substitutes for those ingredients, such as crude glycerol. This study aimed to evaluated the metabolism of crossbred Boer finishing goats fed diets containing crude glycerin from biodiesel production. Thirty-two crossbred, castrated goat of age were distributed in a fully randomized experimental design with four treatments and eight replicates. The experiment lasted 69 days, and goats were fed sorghum silage and concentrate, with the inclusion of crude glycerin in the diet at levels of 0, 50, 100, and 150 g/kg on a dry matter basis. The diets did not have an effect (p > 0.05) on the serum urea levels. Increasing dietary crude glycerin levels did not the influence the metabolic or urinary profiles (p > 0.05). The liver tissue of the goats fed diets containing the highest crude glycerin inclusion levels showed deleterious effects. The inclusion of crude glycerin with approximately 6.6 g/kg methanol caused deleterious effects to the liver tissue of Boer crossbred goats as the glycerin concentrations increased. However, glycerin levels did not cause deleterious effects on the liver tissue or on the serum or urinary profiles. The use of crude glycerin with lower methanol content is recommended for goat diets.

AIMS: To summarise the evidence on barriers to and facilitators of population adherence to prevention and control measures for coronavirus disease 2019 (COVID-19) and other respiratory infectious diseases. METHODS: A qualitative synthesis was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis and the Cochrane Effective Practice and Organization of Care: Qualitative Evidence Synthesis. We performed an electronic search on MEDLINE, Embase and PsycINFO from their inception to March 2023. RESULTS: We included 71 studies regarding COVID-19, pneumonia, tuberculosis, influenza, pertussis and H1N1, representing 5966 participants. The measures reported were vaccinations, physical distancing, stay-at-home policy, quarantine, self-isolation, facemasks, hand hygiene, contact investigation, lockdown, infection prevention and control guidelines, and treatment. Tuberculosis-related measures were access to care, diagnosis and treatment completion. Analysis of the included studies yielded 37 barriers and 23 facilitators. CONCLUSIONS: This review suggests that financial and social support, assertive communication, trust in political authorities and greater regulation of social media enhance adherence to prevention and control measures for COVID-19 and infectious respiratory diseases. Designing and implementing effective educational public health interventions targeting the findings of barriers and facilitators highlighted in this review are key to reducing the impact of infectious respiratory diseases at the population level.

Among several complications related to physiotherapy, osteosarcopenia is one of the most frequent in elderly patients. This condition is limiting and quite harmful to the patient's health by disabling several basic musculoskeletal activities. Currently, the test to identify this health condition is complex. In this study, we use mid-infrared spectroscopy combined with chemometric techniques to identify osteosarcopenia based on blood serum samples. The purpose of this study was to evaluate the mid-infrared spectroscopy power to detect osteosarcopenia in community-dwelling older women (n = 62, 30 from patients with osteosarcopenia and 32 healthy controls). Feature reduction and selection techniques were employed in conjunction with discriminant analysis, where a principal component analysis with support vector machines (PCA-SVM) model achieved 89% accuracy to distinguish the samples from patients with osteosarcopenia. This study shows the potential of using infrared spectroscopy of blood samples to identify osteosarcopenia in a simple, fast and objective way.

PURPOSE: This study aimed to assess and interpret how vitreoretinal surgeons use surgical videos available on social media as complementary learning tools to improve, review, or update their abilities, considering their different levels of expertise. METHODS: In this cross-sectional survey, an online survey was sent to vitreoretinal specialists and fellows. RESULTS: This survey included 258 participants, of whom 53.88% had been in practice for >10 years (senior surgeons), 29.07% between 4 and 10 years (young surgeons), and 17.05% for <3 years (surgeons in training). Retinal surgical videos available on social media were used by 98.84% of the participants (95% confidence interval, 97.52%-100%). YouTube (91%) was the most common source of videos, and surgeons in training watched more videos on YouTube than senior surgeons. Regarding the preferred method when preparing for a procedure, 49.80% of the participants watched surgical videos available on social media, 26.27% preferred to "consult colleagues", and 18.82% preferred to seek information in scientific articles. Participants valued the most the "image quality" (88%) and presence of "surgical tips and tricks" (85%). CONCLUSION: Surgical videos can provide benefits in acquiring strategic skills, such as decision-making, surgical planning, and situational awareness. Retina surgeons used them as teaching aids regardless of their level of expertise, despite being relatively more valuable to surgeons in training or young surgeons.
