Full Robotic Whole Graft Liver Transplantation: A Step Into The Future.

OBJECTIVE: To report the first European series of full robotic whole liver transplantation (RLT) with technical details and future perspectives. SUMMARY BACKGROUND DATA: Few cases of liver transplantation with a minimally invasive approach using partial grafts have been reported so far, and no cases of robotic whole liver transplantation have been reported in the scientific literature. METHODS: The adopted technique was full robotic liver hepatectomy, followed by robotic implantation after graft introduction through a small midline incision. Patients presenting with Hepatocellular Carcinoma (HCC) in liver cirrhosis with a small caudate lobe, low degree of portal hypertension, no porto-mesenteric thrombosis, as well as low MELD patients have been considered ideal candidates. RESULTS: Six patients underwent RLT between February and March 2024 at Lisbon and Modena University Liver Transplant Centers. Warm ischemia time during RLT ranged between 55 and 90 min, with a total surgery duration between 440 and 710 min. The median total operative time was 595 (±111,3) minutes. Only one recipient had prolonged hyperbilirubinemia, which was safely treated. The median in-hospital stay was 7.5 days, (±4.8 days). CONCLUSIONS: RLT is a promising technique to further reduce the impact of liver transplantation thanks to smaller incision, gentle tissue manipulation, high magnification and precision for vascular and biliary anastomosis, and reduced postoperative pain. This is the first step toward the demonstration of the feasibility of minimally invasive surgery in liver transplantation, although further selection and technical refinements are needed to improve reproducibility.

Synthetic Colors in Food: A Warning for Children's Health.

This study addressed the harmful effects of artificial colors in pediatric populations, including children diagnosed with Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD), as well as those without behavioral disorders. There is a consensus that synthetic food colorings have several impacts on consumers, especially pediatrics, due to their influence on sensory appeal, which can encourage preference for certain foods. The results revealed that these color additives are directly linked to a series of health problems, with a greater impact on children, including a predisposition to pathological conditions such as carcinogenic, allergenic, mutagenic, cytotoxic, and clastogenic activities, as well as gastrointestinal and respiratory problems, in addition to behavioral changes in children with and without diagnosed disorders. The harms of synthetic dyes in children with or without comorbidities are worrying and require a careful and proactive approach from parents, caregivers and public authorities.

Exercise-based physiotherapeutic interventions in frailty syndrome: A systematic review and meta-analysis.

OBJECTIVE: To identify the effect of exercise interventions on physical frailty in community-dwelling older adults. METHODS: Relevant articles were searched in MEDLINE, LILACS, Scielo, Embase, and PEDro in November 2022, based on a protocol registered in PROSPERO and according to items prescribed in Report for Systematic Reviews and Meta-Analyses, using Health Sciences Descriptors (DeCS) and free terms for search strategy, with no language restrictions. The studies were considered if they had been published between January 2010 and November 2022, and were randomized clinical trials in which pre-frail and frail older community-dwelling adults had undergone exercise-based physical therapy. RESULTS: The systematic review found 5360 citations; after screening, abstract, and full-text screening for eligibility, seven studies were included, involving 1304 participants overall. The exercise modalities differed substantially between studies. The meta-analysis identified a statistically significant difference in frailty between older adults who exercised compared with those who exercised with no or minimal intervention. No heterogeneity between articles was observed, and the risk of bias was considered low according to funnel plot visual inspection. CONCLUSIONS: The results of this review suggest that physical therapy programs are effective in decreasing levels of physical frailty in community-dwelling older adults.

Impact of the use of active methodology on the performance of undergraduate radiology students.

RATIONALE AND OBJECTIVES: Although PBL is widely used in several countries, especially in medicine courses, its application in teaching other higher education courses, which involve fundamentals applied to radiology, is still little explored. Therefore, we aim to evaluate the implementation of Problem-Based Learning (PBL) in a higher education institution's radiology and biomedicine technologist course, focusing on specific radiology-related disciplines. MATERIALS AND METHODS: An interventional study was developed with 78 students. An active methodology model was created and implemented for one of the groups of participants. At the beginning of each semester, students of both groups were evaluated with pre-tests. At the end of the semesters, the students performed a post-test and a validated evaluation of the discipline methodology. Repeated measures generalized linear regressive models with robust error estimators were used to evaluate test outcomes. RESULTS: A significant interaction among the methodologies was found (p=0.020), with better results from students exposed to the active methodology (initial and final grades were 7.18 and 7.57 in the active methodology, respectively, and 7.45 and 6.89 in the traditional methodology, respectively). In addition, students' evaluation regarding the quality of the methodology was favorable to the active methodology with statistical significance (p<0.05) in 16 of the 22 items evaluated. CONCLUSIONS: The students' positive response and performance were attributed to the interaction and innovation of the methodology compared to conventional methods, highlighting the effectiveness of PBL in higher education in radiology and its potential for more participatory and contextualized learning.

Space-temporal analysis of the Specialized Services of the Health Care Network for Persons with Disabilities in Brazil.

Considering the institution of the Care Network for People with Disabilities (RCPD) in Brazil, this study analyzed the spatial distribution and the temporal trend of implementing specialized services that received financial support in the first eight years of this policy. We realized an ecological study based on the National Register of Health Facilities data from April/2012 to March/2020. A joinpoint regression was used for temporal trend analysis, and thematic maps were produced for spatial analysis of rehabilitation modalities and types of services. The most available services were physical and intellectual rehabilitation. The Southeast and Northeast regions had a higher concentration of specialized services. Despite the lower number of services, there was an average annual growth between 9.6% and 41.3%. This finding indicates an increase in specialized services for people with disabilities in the period analyzed, but care gaps are still being verified in the macro-regions of Brazil.

Unusual presentation of pancreatitis: Inguinoscrotal edema mimicking an incarcerated hernia - a case report.

INTRODUCTION: In rare instances, pancreatitis can manifest as inguinal edema without typical abdominal symptoms, posing diagnostic challenges. CASE PRESENTATION: We report a case of a man in his 40s, with alcohol addiction, who presented with left inguinal pain and swelling but no other abdominal complaints. Physical examination revealed inguinal tenderness and edema, with no hernia signs. Laboratory results showed leukocytosis and elevated C-reactive protein, inconsistent with the patient's symptoms. Abdominopelvic CT scan revealed peripancreatic fat densification and retroperitoneal fluid extending into the inguinal area. No hernia was evident. Extended analysis revealed elevated amylase and lipase levels, sustaining the diagnosis of pancreatitis. The patient responded well to supportive care and was discharged symptom-free. DISCUSSION: Acute pancreatitis emerging as an inguinoscrotal swelling, in the absence of any abdominal symptoms or signs, is extremely rare and can mimic more common causes of inguinoscrotal swellings, such as incarcerated hernias. This case highlights the ability of leaking pancreatic juice to track widely in the retroperitoneal tissues, particularly on the left side. A high level of suspicion, in combination with a CT scan, is essential for achieving an accurate diagnosis and determining the disease's extent. Failure to diagnose correctly could lead to unnecessary surgical procedures and inappropriate/delayed medical care. CONCLUSION: Inguinal edema as the sole presentation of acute pancreatitis is extremely rare. Therefore, it is essential to maintain a high index of suspicion, especially in patients with a history of alcohol consumption, in order to proceed with prompt treatment and avoid unnecessary surgery.

[Differences between men and women in the prevalence of frailty and associated factors among older adults: evidence from ELSI-Brazil]. / Diferenças entre homens e mulheres na prevalência da fragilidade e fatores associados entre adultos mais velhos: evidências do ELSI-Brasil.

Based on a national representative sample of the population aged 50 years or older, this study aimed to estimate the prevalence of frailty among men and women, identify associated sociodemographic and health factors, and estimate the population attributable fraction. Data from the second wave (2019-2021) of the Brazilian Longitudinal Study of Aging (ELSI-Brazil) were used. Frailty was classified based on the number of positive items among unintentional weight loss, exhaustion, low level of physical activity, slow gait, and weakness. The main analyses were based on multinomial logistic regression stratified by sex. The prevalence of frailty was lower in men (8.6%; 95%CI: 6.9; 10.7) than in women (11.9%; 95%CI: 9.6; 14.8), with the most frequent item being the low level of physical activity in both. Age and schooling level were the sociodemographic factors associated with pre-frailty and fragility among men and women. The population attributable fraction was different for frailty between genders. In men, the highest population attributable fraction was due to not having a partner (23.5%; 95%CI: 7.7; 39.2) and low schooling level (18.2%; 95%CI: 6.6; 29,7). In women, higher population attributable fraction values were due to memory deficit (17.1%; 95%CI: 7.6; 26.6), vision deficit (13.4%; 95%CI: 5.1; 21.7), and diabetes mellitus (11.4%; 95%CI: 4.6; 18,1). Similar population attributable fraction levels were observed for heart disease (8.9%; 95%CI: 3.8; 14.1 in women and 8.8%; 95%CI: 2.0; 15.6 in men). Strategies aimed at physical activity have the potential to prevent frailty in both men and women, and the prevention of chronic conditions is more important in women.

Este trabalho, baseado em amostra nacional representativa da população com 50 anos ou mais, objetivou estimar a prevalência da fragilidade entre homens e mulheres, identificar fatores sociodemográficos e de saúde associados e estimar a fração atribuível populacional. Foram utilizados dados da segunda onda (2019-2021) do Estudo Longitudinal da Saúde dos Idosos Brasileiros (ELSI-Brasil). A fragilidade foi classificada pelo número de itens positivos entre perda de peso não intencional, exaustão, baixo nível de atividade física, lentidão da marcha e fraqueza. As análises principais foram baseadas na regressão logística multinomial estratificada por sexo. A prevalência da fragilidade foi menor nos homens (8,6%; IC95%: 6,9; 10,7) do que nas mulheres (11,9%; IC95%: 9,6; 14,8), sendo o item mais frequente o baixo nível de atividade física em ambos. A idade e a escolaridade foram os fatores sociodemográficos associados à pré-fragilidade e à fragilidade entre homens e mulheres. Houve diferença da fração atribuível populacional para fragilidade entre os sexos. Nos homens, a maior fração atribuível populacional foi para não ter companheiro (23,5%; IC95%: 7,7; 39,2) e escolaridade baixa (18,2%; IC95%: 6,6; 29,7). Nas mulheres, maiores frações atribuíveis populacionais foram para déficit de memória (17,1%; IC95%: 7,6; 26,6), déficit da visão (13,4%; IC95%: 5,1; 21,7) e diabetes mellitus (11,4%; IC95%: 4,6; 18,1). Observou-se fração atribuível populacional semelhante para doença cardíaca (8,9%; IC95%: 3,8; 14,1, em mulheres; e 8,8%; IC95%: 2,0; 15,6, em homens). Estratégias voltadas para a prática de atividade física têm o potencial de prevenir a fragilidade em ambos os sexos, enquanto a prevenção de condições crônicas é mais importante nas mulheres.

Este estudio tuvo por objetivo estimar, utilizando una muestra nacional representativa de la población de 50 años o más, la prevalencia de la fragilidad entre hombres y mujeres, identificar los factores sociodemográficos y de salud asociados, y calcular la fracción atribuible a la población. Se utilizaron datos de la 2ª ola (2019-2021) del Estudio Longitudinal de Salud de los Ancianos Brasileños (ELSI-Brasil). La fragilidad se clasificó por el número de elementos positivos entre pérdida de peso no intencional, agotamiento, bajo nivel de actividad física, marcha lenta y debilidad. Los principales análisis se basaron en la regresión logística multinomial estratificada por sexo. La prevalencia de fragilidad fue menor en los hombres (8,6%; IC95%: 6,9; 10,7) que en las mujeres (11,9%; IC95%: 9,6; 14,8), y como ítem más frecuente el bajo nivel de actividad física en ambos. La edad y el nivel educativo fueron los factores sociodemográficos asociados a la pre-fragilidad y la fragilidad entre hombres y mujeres. Hubo una diferencia en fracción atribuible a la población para la fragilidad entre los sexos. Entre los hombres, la fracción atribuible a la población más elevada fue no tener pareja (23,5%; IC95%: 7,7; 39,2) y bajo nivel educativo (18,2%; IC95%: 6,6; 29,7). Entre las mujeres, las fracción atribuible a la población más elevadas fueron déficit de memoria (17,1%; IC95%: 7,6; 26,6), déficit de visión (13,4%; IC95%: 5,1; 21,7) y diabetes mellitus (11,4%; IC95%: 4,6; 18,1). Se observaron fracción atribuible a la población similares para enfermedades cardíacas (8,9%; IC95%: 3,8; 14,1 en mujeres, y 8,8%; IC95%: 2,0; 15,6 en hombres). Las estrategias dirigidas a la actividad física tienen el potencial de prevenir la fragilidad en ambos sexos, mientras que la prevención de enfermedades crónicas es más necesaria en las mujeres.

The risk of COVID-19 in Cushing's disease is independently related to disease activity (hypercortisolism) and obesity.

Objective: To evaluate the cumulative incidence, risk factors, and outcomes of COVID-19 in patients with Cushing's disease (CD). Subjects and methods: In all, 60 patients with CD following up in our outpatient clinic answered via phone interview a questionnaire about the occurrence of COVID-19 infection documented by RT-PCR (including the diagnosis date and clinical outcome) and vaccination status. Clinical and biochemical data on disease activity (hypercortisolism) and comorbidities (obesity, diabetes mellitus, and hypertension) were obtained from the patients' electronic medical records. Risk ratios (RRs) of risk factors were obtained using univariate and multivariate analyses. Results: The cumulative incidence of COVID-19 in patients with CD during the observation period was 31.7%, which was higher than that in the general reference population (9.5%). The cumulative incidence of COVID-19 was significantly higher in patients with hypercortisolism (57% versus 17% in those without hypercortisolism, p = 0.012) and obesity (54% versus 9% in those without obesity, p < 0.001) but not in patients with hypertension or diabetes mellitus. On multivariate analysis, hypercortisolism and obesity were each independent risk factors for COVID-19 (RR 2.18, 95% CI 1.06-4.46, p = 0.033 and RR 5.19, 95% CI 1.61-16.74, p = 0.006, respectively). Conclusion: The incidence of COVID-19 in patients with CD was associated with hypercortisolism, as expected, and obesity, a novel and unexpected finding. Thus, correction of hypercortisolism and obesity should be implemented in patients with CD during the current and future COVID-19 outbreaks.

Leisure Attitude, Self-Rated Health, and Psychological Well-Being in Older Adults: A Moderated Mediation Model.

Purpose: A positive leisure attitude among older adults may have a beneficial effect on psychological well-being, both directly and indirectly by fostering a more positive perception of one's health. This paper presents a correlational design that explores associations among leisure attitude, self-rated health, and psychological well-being, and analyzes the potential moderating role of gender in these relationships. Patients and Methods: The sample was selected using simple random probability sampling (N= 409; 61.9% female; Mean age = 72.9; SD = 8.43¸ Range of age 53 to 93 years). Diverse sociodemographic information was collected, and leisure attitudes, self-perceived health, and psychological well-being (positive affect and emotional ties) were assessed. Results: The results revealed a positive effect of leisure attitude on self-rated health and psychological well-being, with self-rated health fully mediating the association between the behavioral component of leisure attitude and psychological well-being. Furthermore, the moderating effect of gender on the relationship between self-rated health and psychological well-being was stronger among men. Conclusion: Positive cognitive and emotional perceptions of leisure among older adults seem to benefit psychological well-being and improve self-rated health, thereby contributing to healthy ageing.

Does the intensity of pain and disability affect health-related quality of life of older adults with back pain? Multilevel analysis between Brazil and Netherlands: a cross-sectional study of the BACE consortium.

BACKGROUND: The prognosis of back pain (BP) in the older adults is less favorable than in younger adults and progress to adverse outcomes and consequent worsening of health-related quality of life (HRQoL). The present study aimed to verify the association between BP intensity, disability and HRQoL in older adults residents in Brazil and Netherlands, and to evaluate whether the country of residence influences the associations. METHODS: Data were collected from 602 Brazilian and 675 Dutch participants with a new episode of BP from the Back Complaints in Elders (BACE) consortium. For the present study, a cross section was used. Pain intensity and disability were assessed using the Numerical Rating Scale (NRS) and the Roland-Morris Disability Questionnaire (RMDQ), respectively. HRQoL was assessed using the Short Form Health Survey (SF-36) quality of life questionnaire. Age, sex, and education were descriptive variables. Pain intensity (NPS score) and country were the independent variables and quality of life assessed by each SF domain - 36 was the dependent variable. Analysis of models at the individual level was performed to verify the association between pain and disability, also HRQoL in Netherlands and Brazil in the total sample. The multilevel model was used to verify whether the older adults person's country of residence influenced this relationship. RESULTS: The average age of the participants was 67.00 (7.33) years. In the total sample, linear regression analysis adjusted for sex and age showed a significant association between BP intensity scores and HRQoL, for all domains. There was no association between disability and HRQoL. In the multilevel analysis, there was an association between BP intensity and HRQoL in all domains and an association between the country of residence and HRQoL, influencing the effect of pain, in all domains, except for the physical functioning. CONCLUSION: Socioeconomic and cultural aspects of different countries can affect the perception of the elderly about their HRQoL in the presence of BP. Pain and disability in Brazilian and Dutch older adults ones are experienced differently in relation to their HRQoL.

Investigation of the involvement of platelet-activating factor in the control of hypertension by aerobic training. A randomized controlled trial.

Although studies have demonstrated the effectiveness of exercise in controlling systemic arterial hypertension (SAH), the mechanisms involved in this effect are still poorly understood. Thus, this study investigated the impact of aerobic training on the relationship between platelet-activating factor (PAF) circulating levels and blood pressure in hypertensives. Seventy-seven hypertensive subjects were enrolled in this randomized controlled trial (age 66.51 ± 7.53 years, body mass 76.17 ± 14.19 kg). Participants were randomized to two groups: the intervention group (IG, n = 36), composed of hypertensive individuals submitted to an aerobic training protocol, and the control group (CG, n = 41), composed of non-exercised hypertensives. Body mass index, arterial blood pressure, quality of life, respiratory muscle strength, and functional capacity were assessed before and after 12 weeks. PAF and plasma cytokine levels were also evaluated respectively by liquid chromatography coupled with mass spectrometry and enzyme-linked immunosorbent assay. Aerobic training promoted a significant reduction in blood pressure while functional capacity, expiratory muscle strength, and quality of life, PAFC16:0 and PAFC18:1 plasma levels were increased in comparison to the CG (p < 0.05). In addition, multiple correlation analysis indicated a positive correlation [F (3.19) = 6.322; p = 0.001; R2adjusted = 0.499] between PAFC16:0 levels and expiratory muscle strength after aerobic training. Taken together, our findings indicate that PAF may be involved in the indirect mechanisms that control SAH, being mainly associated with increased respiratory muscle strength in hypertensive subjects undergoing aerobic training.

Longitudinal associations between stroke-related neurologic deficits and course of basic activities of daily living up to six months after stroke.

PURPOSE: To investigate the course of basic activities of daily living (ADL) from admission up to six months after the stroke and the longitudinal associations between stroke-related neurological deficits at admission to the stroke unit and course of basic ADL. MATERIALS AND METHODS: 180 individuals with a first-ever stroke were assessed at admission to the stroke unit and at follow-ups of three and six months. Stroke-related neurological deficits were assessed at admission with the National Institutes of Stroke Scale (NIHSS). Independence in basic ADL was assessed at admission and three and six months after the stroke by the Modified Barthel Index (MBI). Generalized Estimating Equations (GEE) were performed. RESULTS: Dependence in basic ADL reduced overtime, with most changes occurring over the first three months. Individuals, who had moderate/severe stroke-related neurological deficits (NIHSS ≥6) at admission, had higher chances of becoming more dependent in activities related to feeding (OR:1.27;95%CI = 1.03-1.55;p = 0.021), bathing (OR:1.30;95%CI = 1.11-1.50;p = 0.0005), dressing (OR:1.19;95%CI = 1.04-1.36;p = 0.010), transfers (OR:1.24;95%CI = 1.05-1.46;p = 0.0072), stair climbing (OR:1.46;95%CI = 1.27-1.66;p < 0.0001), and ambulation (OR:1.21;95%CI = 1.02-1.43;p < 0.0001). CONCLUSIONS: Decreases in dependence in basic ADL occurred mainly over three months after the stroke and showed different patterns for specific ADL. Baseline moderate/severe stroke-related neurological deficits were associated with poor functional status in basic ADL over the follow-up period.

Stroke survivors experience dependence in basic activities of daily living (ADL) which is reduced over six months after the stroke and showed different individual variability in patterns of recovery.Patients with moderate/severe stroke-related neurological deficits had higher chances of becoming dependent in activities related to feeding, bathing, dressing, transfers, stair climbing, and ambulation.Rehabilitation professionals should consider assessing stroke-related neurologic deficits within the first hours after stroke, with particular attention to individuals with moderate/severe impairments.

Changes in splenic tissue and immune response profile of Schistosoma mansoni infected mice submitted to chronic ethanol intake.

In Schistosoma mansoni infection, the spleen is one of the organs affected, causing its enlargement (splenomegaly). Intake of ethanol through alcoholic beverages can cause spleen atrophy and interfere with immune activity. To gain knowledge of this association on the spleen and on the immune response profile, male mice were used as an experimental model. These animals were divided into four groups: C. control; EC. uninfected/ethanol gavage; I. infected; and IE. infected/ethanol gavage. Groups I and IE were infected with about 100 cercariae (BH strain) of S. mansoni and in the fifth week of infection, gavage 200 µL/day/animal of 18 % ethanol was started for 28 consecutive days. At the end of the gavage (9th week of infection) all animals were euthanized. The spleen was removed and longitudinally divided in two parts. After histological processing, the sections were stained with H&E and Gomori's Reticulin for histopathological and stereological analyses, white pulp morphometry and quantification of megakaryocytes. The other fragment was macerated (in laminar flow) and the cell suspension, after adjusting the concentration (2 × 106), was plated to obtain cytokines produced by spleen cells that were measured by flow cytometry (Citometric Bead Array). Histopathological and quantitative analyzes in the spleen of the IE group showed an increase in the number of trabeculae and megakaryocytes, a decrease in reticular fibers, as well as important organizational changes in the white pulp and red pulp. Due to the decrease in the levels of cytokines measured and the result of the calculation of the ratio between the IFN-y and IL-10 cytokines (p = 0.0079) of the infected groups, we suggest that ethanol decreased the inflammatory and anti-inflammatory response generated by the infection (group IE, the production of cytokines was significantly decreased (p < 0.01). These changes demonstrate that ethanol ingestion interferes with some parameters of experimental S. mansoni infection, such as changes in splenic tissue and in the pattern of cytokine production.

Analytical validation and algorithm improvement of HepatoPredict kit to assess hepatocellular carcinoma prognosis before a liver transplantation.

Objectives: To verify the analytical performance of the HepatoPredict kit, a novel tool developed to stratify Hepatocellular Carcinoma (HCC) patients according to their risk of relapse after a Liver Transplantation (LT). Methods: The HepatoPredict tool combines clinical variables and a gene expression signature in an ensemble of machine-learning algorithms to forecast the benefit of a LT in HCC patients. To ensure the accuracy and reliability of this method, extensive analytical validation was conducted to verify its specificity and robustness. The experiments were designed following the guidelines for multi-target genomic assays such as ISO201395-2019, MIQE, CLSI-MM16, CLSI-MM17, and CLSI-EP17-A. The validation process included reproducibility between operators and between RNA extractions and RT-qPCR runs, and interference of input RNA levels or varying reagent levels. A recently retrained version of the HepatoPredict algorithms was also tested. Results: The validation process demonstrated that the HepatoPredict kit met the required standards for robustness (p > 0.05), analytical specificity (inclusivity of 95 %), and sensitivity (LoB, LoD, linear range, and amplification efficiency between 90 and 110 %). The operator, equipment, input RNA, and reagents used had no significant effect on the HepatoPredict results. Additionally, the testing of a recently retrained version of the HepatoPredict algorithm, showed that this new version further improved the accuracy of the kit and performed better than existing clinical criteria in accurately identifying HCC patients who are more likely to benefit LT. Conclusions: Even with the introduced variations in molecular and clinical variables, the HepatoPredict kit's prognostic information remains consistent. It can accurately identify HCC patients who are more likely to benefit from a LT. Its robust performance also confirms that it can be easily integrated into standard diagnostic laboratories.

Identification of Chromoblastomycosis and Phaeohyphomycosis Agents through ITS-RFLP.

Chromoblastomycosis (CBM) and phaeohyphomycosis (FEO) are infections caused by melanized filamentous fungal agents, primarily found in tropical and subtropical regions. Both infections pose significant challenges for the correct identification of the causative agent due to their morphological similarity, making conventional methods of morphological analysis highly subjective. Therefore, molecular techniques are necessary for the precise determination of these species. In this regard, this study aimed to contribute to a new methodology based on PCR-RFLP for the identification of agents causing CBM and FEO. Sequences from the Internal Transcribed Spacer (ITS) region were used to identify potential restriction enzyme sites in silico, followed by in vitro validation using the selected restriction enzymes. The obtained results were compared with species identification through morphological analyses and sequencing. The results demonstrated that the PCR-RFLP applied in this study accurately identified two major agents of chromoblastomycosis, Fonsecaea pedrosoi and Fonsecaea monophora, as well as Cladophialophora bantiana and Exophiala dermatitidis, both causative agents of phaeohyphomycosis. In this context, the proposed assay can complement current methods for identifying these species, aiding in diagnosis, and contributing to the proper management of these infections.

Perioperative Changes in Serum Transaminase Levels: Impact on Postoperative Morbidity Following Liver Resection of Hepatocellular Carcinoma.

OBJECTIVES: To define how dynamic changes in pre- versus post-operative serum aspartate aminotransferase (AST) and alanine aminotransaminase (ALT) levels may impact postoperative morbidity after curative-intent resection of hepatocellular carcinoma (HCC). BACKGROUND: Hepatic ischemia/reperfusion can occur at the time of liver resection and may be associated with adverse outcomes following liver resection. METHODS: Patients who underwent curative resection for HCC between 2010-2020 were identified from an international multi-institutional database. Changes in AST and ALT (CAA) on postoperative day (POD) 3 versus preoperative values () were calculated using the formula: based on a fusion index via Euclidean norm, which was examined relative to the comprehensive complication index (CCI). The impact of CAA on CCI was assessed by the restricted cubic spline regression and Random Forest analyses. RESULTS: A total of 759 patients were included in the analytic cohort. Median CAA was 1.7 (range, 0.9 to 3.25); 431 (56.8%) patients had a CAA<2, 215 (28.3%) patients with CAA 2-5, and 113 (14.9%) patients had CAA ≥5. The incidence of post-operative complications was 65.0% (n=493) with a median CCI of 20.9 (IQR, 20.9-33.5). Spline regression analysis demonstrated a non-linear incremental association between CAA and CCI. The optimal cutoff value of CAA=5 was identified by the recursive partitioning technique. After adjusting for other competing risk factors, CAA≥5 remained strongly associated with risk of post-operative complications (Ref. CAA<5, OR 1.63, 95%CI 1.05-2.55, P=0.03). In fact, the use of CAA to predict post-operative complications was very good in both the derivative (AUC 0.88) and external (ACU 0.86) cohorts (n=1137). CONCLUSIONS: CAA was an independent predictor of CCI after liver resection for HCC. Use of routine labs such as AST and ALT can help identify patients at highest risk of post-operative complications following HCC resection.

Influence of CK2 protein kinase activity on the interaction between Trypanosoma cruzi and its vertebrate and invertebrate hosts.

Chagas disease, endemic from Latin America, is caused by Trypanosoma cruzi and is transmitted by triatomine feces. This parasite undergoes complex morphological changes through its life cycle, promoted by significant changes in signal transduction pathways. The activity of protein kinase CK2 has been described in trypanosomatids. Using a specific peptide and radioactive ATP, we identified CK2 activity on the cellular surface and the cytoplasmic content in Trypanosoma cruzi, apart from the secreted form. Dephosphorylated casein promoted an increase of 48% in the secreted CK2 activity. Total extract of peritoneal macrophages from BALB/c and inactivated human serum promoted an increase of 67% and 36%, respectively, in this activity. The protein secreted by parasites was purified by HPLC and had shown compatibility with the catalytic subunit of mammalian CK2. Incubation of the parasites with CK2 inhibitors, added to the culture medium, prevented their growth. The opposite was observed when CK2 activators were used. Results of interaction between Trypanosoma cruzi and the gut of the vector have revealed that, in the presence of CK2 inhibitors, there is a reduction in the association rate. A similar inhibition profile was seen in the Trypanosoma cruzi-macrophages interaction, confirming the importance of this enzyme in the life cycle of this protozoan.

R3-Walk and R6-Walk, Simple Clinical Equations to Accurately Predict Independent Walking at 3 and 6 Months After Stroke: A Prospective, Cohort Study.

OBJECTIVE: To investigate if independent walking at 3 and 6 months poststroke can be accurately predicted within the first 72 hours, based on simple clinical bedside tests. DESIGN: Prospective observational cohort study with 3-time measurements: immediately after stroke, and 3 and 6 months poststroke. SETTING: Public hospital. PARTICIPANTS: Adults with first-ever stroke evaluated at 3 (N=263) and 6 (N=212) months poststroke. INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: The outcome of interest was independent walking at 3 and 6 months after stroke. Predictors were age, walking ability, lower limb strength, motor recovery, spatial neglect, continence, and independence in activities of daily living. RESULTS: The equation for predicting walking 3 months poststroke was 3.040 + (0.283 × FAC baseline) + (0.021 × Modified Barthel Index), and for predicting walking 6 months poststroke was 3.644 + (-0.014 × age) + (0.014 × Modified Barthel Index). For walking ability 3 months after stroke, sensitivity was classified as high (91%; 95% CI: 81-96), specificity was moderate (57%; 95% CI: 45-69), positive predictive value was high (76%; 95% CI: 64-86), and negative predictive value was high (80%; 95% CI: 60-93). For walking ability 6 months after stroke, sensitivity was classified as moderate (54%; 95% CI: 47-61), specificity was high (81%; 95% CI: 61-92), positive predictive value was high (87%; 95% CI: 70-96), and negative predictive value was low (42%; 95% CI: 50-73). CONCLUSIONS: This study provided 2 simple equations that predict walking ability 3 and 6 months after stroke. This represents an important step to accurately identify individuals, who are at high risk of walking dependence early after stroke.

Effect of aquatic exercise programs according to the International Classification of Functionality, Disability and Health domains in individuals with Parkinson's disease: a systematic review and meta-analysis with GRADE quality assessment.

PURPOSE: To investigate the effects of aquatic exercise programs (AEP) in body structure and function, activity, and participation outcomes in individuals with Parkinson's disease (PD) with mild to moderate disability levels. METHODS: Six databases were searched from inception until November 2022. Randomized clinical trials that used AEP alone, AEP combined and/or compared two types of AEP were included. The quality of evidence was assessed by the GRADE approach and the standardized mean differences (SMD) were calculated the meta-analysis. RESULTS: Twelve studies (n = 380) were included. AEP alone was superior to active control in improving body structure and function outcome: postural balance (low evidence, SMD = 0.47, p = 0.02). No statistically significant differences were found for the other body structure and function outcomes: lower limb muscle strength (p = 0.14) and depressive symptoms (p = 0.79), activity outcomes: mobility (p = 0.32) and participation outcomes: quality of life (p = 0.05). AEP combined showed no statistically significant difference for the outcomes of body structure and function: postural balance (p = 0.11) and activity: mobility (p = 0.21) when compared to active control. CONCLUSION: AEP showed positive effects on body structure and function outcome (postural balance) in individuals with PD with mild to moderate disability levels while, no significant improvements were noticed for activity and participation outcomes.IMPLICATIONS FOR REHABILITATIONOur findings indicate that aquatic exercise programs (AEP) lead to significant improvements on body structure and function (i.e., postural balance) in individuals with Parkinson's disease (PD).The AEP evaluated in this study implemented postural balance, gait, single and double training, as well as aerobic exercises, trunk mobility exercises, and Ai Chi.The average duration, frequency, and total time implemented were 50 minutes, three times a week, for seven weeks, respectively.Considering the potential benefits identified in this study, AEP can be recommended as an adjunct treatment strategy for individuals with PD.Additionally, the use of the International Classification of Functionality, Disability and Health on the development of rehabilitation treatment plans is advised.
