RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

AIMS: To compare the effects of bladder training (BT) versus BT with pelvic floor muscle training (PFMT) in women with overactive bladder (OAB) symptoms. METHODS: Randomized controlled clinical trial including women with OAB symptoms, randomized into two groups: BT versus BT + PFMT. For 12 consecutive weeks, the women received home BT. The BT + PFMT performed supervised PFMT, once/week, associated at home PFMT protocol. Primary outcomes were urinary urgency, daytime voiding frequency, nocturia and urgency urinary incontinence assisted by both 3-day bladder diary and International Consultation on Incontinence OAB (ICIQ-OAB) questionnaire. Secondary outcomes were 24-h pad test and Patient Global Impression of Improvement. T-test, analysis of variance, Mann-Whitney (SPSS 20.0) and power/effect size (G-power) were applied in data analyses. RESULTS: Sixty-three women were included (B = 31; BT + PFMT = 32). There was no significant statistical difference between groups in terms of urinary symptoms: daytime frequency (BT: pre: 11.59 [±5.80], post: 9.10 [±4.05]; BT + PFMT: pre: 10.67 [±3.73], post: 8.08 [±3.38]) p = 0.75; nocturia: (BT: pre: 1.46 [±0.91], post: 0.82 [±0.82]; BT + PFMT: pre: 1.80 [±2.26], post: 0.82 [±1.15]) p = 0.70; urinary urgency (BT: pre: 3.22 [±4.70], post: 4.49 [±4.32]; BT + PFMT: pre: 6.87 [±5.60], post: 6.15 [±4.52]) p = 0.10; ICIQ-OAB total score: (BT: pre: 9.16 [±2.55], post: 6.32 [±3.77]; (BT + PFMT: pre: 9.75 [±2.06], post: 5.06 [±3.44] p = 0.30. CONCLUSIONS: Supervised PFMT added to BT did not provide further improvements than isolated BT in women with OAB symptoms.

RESUMEN

Actinomycetes are a distinct group of filamentous bacteria. The Streptomyces genus within this group has been extensively studied over the years, with substantial contributions to society and science. This genus is known for its antimicrobial production, as well as antitumor, biopesticide, and immunomodulatory properties. Therefore, the extraordinary plasticity of the Streptomyces genus has inspired new research techniques. The newest way of exploring Streptomyces has comprised the discovery of new natural metabolites and the application of emerging tools such as CRISPR technology in drug discovery. In this narrative review, we explore relevant published literature concerning the ongoing novelties of the Streptomyces genus.

RESUMEN

BACKGROUND: Frailty is a multidimensional syndrome leading to a higher hospitalization. However, few studies explicitly analyze whether measures of effective primary care modify the relationship between frailty and hospital admission. METHODS: This cross-sectional study included data from the second wave of the Brazilian Longitudinal Study of Aging (ELSI-Brazil), a representative community-based study with older adults aged 50 years and over, conducted in 2019-2021. Self-reported hospital admission in the past 12 months was the outcome. Frailty included the 5 phenotypic criteria: weight loss, exhaustion, low physical activity, weakness, and slowness. The effective primary care index included 12 attributes indicators, continuously. Statistical analyzes comprised logistic regression. RESULTS: Among the 7,436 study participants, frailty (odds ratio [OR] 2.17; 95% confidence intervals [95% CI] 1.31-3.62) and effective primary care index (OR 1.10; 95% CI 1.03-1.16) were positively associated with higher hospitalization. Interaction revealed that while effective primary care was positively associated with hospitalization, this association was different among frail older adults (OR 0.80; 95% CI 0.65-0.99). After stratification by frailty status, positive association with hospitalization remained only among prefrail and nonfrail individuals. The predicted probability of hospitalization tended to decrease along with higher primary care index values among frail older adults and became similar to prefrail/nonfrail at the highest end of the scale. CONCLUSIONS: Effective primary care decreases the likelihood of hospital admission among frail older adults. Interventions for delaying frailty should be initiated in primary care along with policies to strengthen primary care's organizational and provider/team-level attributes.

RESUMEN

PURPOSE: Brazilian nutrition recommendations for bariatric and metabolic surgery aim to provide knowledge, based on scientific evidence, on nutritional practices related to different surgical techniques in the surgical treatment of obesity and metabolic diseases. MATERIALS AND METHODS: A systematic literature search was carried out with the appropriate MeSH terms using Medline/Pubmed/LiLACS and the Cochrane database, with the established criteria being based on the inclusion of articles according to the degree of recommendation and strength of evidence of the Classification of Recommendations, Evaluation, Development, and Evaluation System (GRADE). RESULTS: The recommendations that make up this guide were gathered to assist in the individualized clinical practice of nutritionists in the nutritional management of patients with obesity, including nutritional management in the intragastric balloon; pre and postoperative nutritional treatment and supplementation in bariatric and metabolic surgeries (adolescents, adults, elderly, pregnant women, and vegetarians); hypoglycemia and reactive hyperinsulinemia; and recurrence of obesity, gut microbiota, and inflammatory bowel diseases. CONCLUSION: We believe that this guide of recommendations will play a decisive role in the clinical practice of nutritionists who work in bariatric and metabolic surgery, with its implementation in health services, thus promoting quality and safety in the treatment of patients with obesity. The concept of precision nutrition is expected to change the way we understand and treat these patients.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the validity and reliability of the Short Form Brief Pain Inventory (SF-BPI) for community-dwelling Brazilian older adults with chronic neuropathic, nociceptive and nociplastic pain. METHODS: Cross-sectional psychometric testing was conducted in a convenience sample, n=114 (66.5 ± 4.9 years). RESULTS: The 2-factor structure of the SF-BPI was ratified by confirmatory factor analysis. Convergent validity was found between the SF-BPI and the Present Pain Intensity (PPI). There was good overall internal consistency (Cronbach's α: 0.87). Test-retest reliability was excellent for pain intensity and interference scores of the SF-BPI (ICC: 0.90 and 0.96, respectively), as well as inter-rater reliability for both dimensions (ICC: 0.77). CONCLUSION: The findings support the validity and reliability of the SF-BPI for community-dwelling older adults with chronic pain and may contribute to health professionals having a brief multidimensional assessment for more effective therapeutic approaches in this population.

RESUMEN

OBJECTIVE: To propose a new decision algorithm combining biomarkers measured in a tumor biopsy with clinical variables, to predict recurrence after liver transplantation (LT). BACKGROUND: Liver cancer is one of the most frequent causes of cancer-related mortality. LT is the best treatment for hepatocellular carcinoma (HCC) patients but the scarcity of organs makes patient selection a critical step. In addition, clinical criteria widely applied in patient eligibility decisions miss potentially curable patients while selecting patients that relapse after transplantation. METHODS: A literature systematic review singled out candidate biomarkers whose RNA levels were assessed by quantitative PCR in tumor tissue from 138 HCC patients submitted to LT (>5 years follow up, 32% beyond Milan criteria). The resulting 4 gene signature was combined with clinical variables to develop a decision algorithm using machine learning approaches. The method was named HepatoPredict. RESULTS: HepatoPredict identifies 99% disease-free patients (>5 year) from a retrospective cohort, including many outside clinical criteria (16%-24%), thus reducing the false negative rate. This increased sensitivity is accompanied by an increased positive predictive value (88.5%-94.4%) without any loss of long-term overall survival or recurrence rates for patients deemed eligible by HepatoPredict; those deemed ineligible display marked reduction of survival and increased recurrence in the short and long term. CONCLUSIONS: HepatoPredict outperforms conventional clinical-pathologic selection criteria (Milan, UCSF), providing superior prognostic information. Accurately identifying which patients most likely benefit from LT enables an objective stratification of waiting lists and information-based allocation of optimal versus suboptimal organs.

RESUMEN

BACKGROUND: Postoperative infectious complications may be associated with a worse long-term prognosis for patients undergoing surgery for a malignant indication. The current study aimed to characterize the impact of postoperative infectious complications on long-term oncologic outcomes among patients undergoing resection for hepatocellular carcinoma (HCC). METHODS: Patients who underwent curative-intent resection for HCC between 2000 and 2017 were identified from an international multi-institutional database. The relationship between postoperative infectious complications, overall survival (OS), and recurrence-free survival (RFS) was analyzed. RESULTS: Among 734 patients who underwent HCC resection, 269 (36.6%) experienced a postoperative complication (Clavien-Dindo grade 1 or 2 [n = 197, 73.2%] vs grade 3 and 4 [n = 69, 25.7%]). An infectious complication was noted in 81 patients (11.0%) and 188 patients (25.6%) had non-infectious complications. The patients with infectious complications had worse OS (median: infectious complications [46.5 months] vs no complications [106.4 months] [p < 0.001] and non-infectious complications [85.7 months] [p < 0.05]) and RFS (median: infectious complications [22.1 months] vs no complications [45.5 months] [p < 0.05] and non-infectious complications [38.3 months] [p = 0.139]) than the patients who had no complication or non-infectious complications. In the multivariable analysis, infectious complications remained an independent risk factor for OS (hazard ratio [HR], 1.7; p = 0.016) and RFS (HR, 1.6; p = 0.013). Among the patients with infectious complications, patients with non-surgical-site infection (SSI) had even worse OS and RFS than patients with SSI (median OS: 19.5 vs 70.9 months [p = 0.010]; median RFS: 12.8 vs 33.9 months [p = 0.033]). CONCLUSION: Infectious complications were independently associated with an increased long-term risk of tumor recurrence and death. Patients with non-SSI versus SSI had a particularly worse oncologic outcome.

RESUMEN

INTRODUCTION: Cabergoline is the treatment of choice for prolactinomas. However, 10-20% of prolactinomas are resistant to cabergoline. Metformin, a biguanide widely used in the treatment of diabetes mellitus, has been shown to reduce prolactin secretion in various pituitary tumor-cell lineages both in vitro and in vivo and in human pituitary adenomas in vitro. The aim of this study is to test the effects of metformin addition to cabergoline treatment on prolactin levels in patients with resistant prolactinomas. SUBJECTS AND METHODS: This is a prospective study performed in an outpatient clinic in a reference center. Ten adult patients (26-61 years) with prolactinomas (7 M), persistent hyperprolactinemia (38-386 ng/mL) under cabergoline treatment (2-7 mg/week) for at least 6 months (6-108 months), features of metabolic syndrome, and not taking metformin were included. Metformin (1.0-2.5 g v.o./day) was given according to patients' tolerance. Cabergoline doses were kept unchanged. Serum prolactin levels were measured before and after short- (30-60 days) and long-term (120-180 days) metformin treatment. RESULTS: Mean prolactin levels did not show any significant changes (148 ± 39 vs. 138 ± 42 vs. 133 ± 39 ng/mL, before, at 30-60 days, and at 120-180 days, respectively, p = 0.196) after metformin (mean dose: 1.25 g/day; range: 1.0-2.0 g/day). No patient reached a normal prolactin level during metformin treatment. Two patients were considered partial responders for exhibiting prolactin decreases ≥50% at a single time point during metformin. CONCLUSION: Metformin addition to ongoing high-dose cabergoline treatment in patients with cabergoline-resistant prolactinomas failed to show a consistent inhibitory effect in serum prolactin levels.

RESUMEN

AIM: Our objective was to investigate whether there is an interaction between the COVID-19 pandemic, demographic characteristics and erectile/sexual (E/S) function in individuals from Latin America. MATERIALS AND METHODS: Cross-sectional study which included Latin American individuals over 18 years old, recruited through social media and interviewed between July and August 2020 by online surveys (Google Forms) in Portuguese and Spanish languages. The E/S function was evaluated through the following questionnaires: Simplified International Index of Erectile Function (IIEF-5) and Female Sexual Function Index (FSFI); while post-traumatic stress disorder (PTSD) triggered by the COVID-19 pandemic was assessed through the Impact of Event Scale Revised (IES-R). The data was analyzed by T Student, bivariate and multivariate logistic regression, with significance determined by the Wald test (p<0.05), using the R software v4.0. RESULTS: Out of the 2016 individuals that responded to the survey, 1986 were included and 743 of them presented E/S dysfunction. PTSD occurrence was greater among people with E/S dysfunction when compared to those without E/S dysfunction, in the total score (males: IES-R=26.54[±19.17] and females: IES-R=35.92[±19.25]) and also in the three domains. It was found that those who do not live with a partner were 74% more likely to have E/S dysfunction, but living with a partner during the pandemic had a greater impact on E/S function. CONCLUSION: A negative interaction between the impact of the COVID-19 pandemic and erectile/sexual function of the Latin American population was observed, with greater implications among the individuals who live with their partners.

RESUMEN

AIM: This study aimed to identify which strategies are being adopted to deal with family restrictions in health units and assess nurses' perceptions of including families in nursing care during the current pandemic. BACKGROUND: Due to the COVID-19 pandemic, health organisations limited access for visitors. INTRODUCTION: Family centred care needs to be guaranteed, and alternatives for face-to-face interaction should be fostered. Therefore, there is an urgent need to rethink the family in nursing care during a pandemic. METHODS: We conducted a descriptive exploratory mixed-method study in Portugal using an electronic questionnaire. The study included 192 nurses recruited using a non-probabilistic convenience sample. The study was reported using the Strengthening the Reporting of Observational Studies in Epidemiology guidelines. RESULTS: A total of 41.1% of participants (n = 79) reported that visits to their services were not authorised, and 66.7% (n = 128) reported resorting to video calls because of the restrictions imposed. Regarding attitude assessment, the average score of the scale was 77.9 (SD = 10.0), ranging between 26 and 98. When analysing the different dimensions of the 'Families' Importance in Nursing Care - Nurses Attitudes' scale, family data stand out as a burden. CONCLUSION: Although a large percentage of participants had a positive attitude towards families and tried to find strategies to maintain family centred care, many nurses still considered the family as a burden. The current COVID-19 pandemic may have aggravated this perception. IMPLICATIONS FOR NURSING PRACTICE, NURSING POLICY AND HEALTH POLICY: The continued implementation of family centred nursing practice is essential for child-well-being, including during the current pandemic. Therefore, having intervention policies with alternative forms of care is highly recommended.

RESUMEN

Background In patients with liver cancer, portal vein embolization (PVE) is recommended to promote liver growth before major hepatectomies. However, the optimal embolization strategy has not been established. Purpose To compare liver regeneration as seen at CT in participants with liver cancer, before major hepatectomies, with N-butyl-cyanoacrylate (NBCA) plus iodized oil versus standard polyvinyl alcohol (PVA) particles plus coils, for PVE. Materials and Methods In this single-center, prospective, randomized controlled trial (Best Future Liver Remnant, or BestFLR, trial; International Standard Randomized Controlled Trial Number 16062796), PVE with NBCA plus iodized oil was compared with standard PVE with PVA particles plus coils in participants with liver cancer. Participant recruitment started in November 2017 and ended in March 2020. Participants were randomly assigned to undergo PVE with PVA particles plus coils or PVE with NBCA plus iodized oil. The primary end point was liver growth assessed with CT 14 days and 28 days after PVE. Secondary outcomes included posthepatectomy liver failure, surgical complications, and length of intensive care treatment and hospital stay. The Mann-Whitney U test was used to compare continuous outcomes according to PVE material, whereas the Χ2 test or Fisher exact test was used for categoric variables. Results Sixty participants (mean age, 61 years ± 11 [standard deviation]; 32 men) were assigned to the PVA particles plus coils group (n = 30) or to the NBCA plus iodized oil group (n = 30). Interim analysis revealed faster and superior liver hypertrophy for the NBCA plus iodized oil group versus the PVA particles plus coils group 14 days and 28 days after PVE (absolute hypertrophy of 46% vs 30% [P < .001] and 57% vs 37% [P < .001], respectively). Liver growth for the proposed hepatectomy was achieved in 87% of participants (26 of 30) in the NBCA plus iodized oil group versus 53% of participants (16 of 30) in the PVA particles plus coils group (P = .008) 14 days after PVE. Liver failure occurred in 13% of participants (three of 24) in the NBCA plus iodized oil group and in 27% of participants (six of 22) in the PVA particles plus coils group (P = .27). Conclusion Portal vein embolization with N-butyl-cyanoacrylate plus iodized oil produced greater and faster liver growth as seen at CT in participants with liver cancer, compared with portal vein embolization with polyvinyl alcohol particles plus coils, allowing for earlier surgical intervention. © RSNA, 2021 Online supplemental material is available for this article.

RESUMEN

BACKGROUNDS: Extrahepatic recurrence of hepatocellular carcinoma (HCC) after surgical resection is associated with unfavorable prognosis. The objectives of the current study were to identify the risk factors and develop a nomogram for the prediction of extrahepatic recurrence after initial curative surgery. METHODS: A total of 635 patients who underwent curative-intent resection for HCC between 2000 and 2017 were identified from an international multi-institutional database. The clinicopathological characteristics, risk factors, and long-term survival of patients with extrahepatic recurrence were analyzed. A nomogram for the prediction of extrahepatic recurrence was established and validated in 144 patients from an external cohort. RESULTS: Among the 635 patients in the derivative cohort, 283 (44.6%) experienced recurrence. Among patients who recurred, 80 (28.3%) patients had extrahepatic ± intrahepatic recurrence, whereas 203 (71.7%) had intrahepatic recurrence only. Extrahepatic recurrence was associated with more advanced initial tumor characteristics, early recurrence, and worse prognosis versus non-extrahepatic recurrence. A nomogram for the prediction of extrahepatic recurrence was developed using the ß-coefficients from the identified risk factors, including neutrophil-to-lymphocyte ratio, multiple lesions, tumor size, and microvascular invasion. The nomogram demonstrated good ability to predict extrahepatic recurrence (c-index: training cohort 0.786; validation cohort: 0.845). The calibration plots demonstrated good agreement between estimated and observed extrahepatic recurrence (p = 0.658). CONCLUSIONS: An externally validated nomogram was developed with good accuracy to predict extrahepatic recurrence following curative-intent resection of HCC. This nomogram may help identify patients at high risk of extrahepatic recurrence and guide surveillance protocols as well as adjuvant treatments.

RESUMEN

BACKGROUND: The impact of tumor necrosis relative to prognosis among patients undergoing curative-intent resection for hepatocellular carcinoma (HCC) remains ill-defined. METHODS: Patients who underwent curative-intent resection for HCC without any prior treatment between 2000 and 2017 were identified from an international multi-institutional database. Tumor necrosis was graded as absent, moderate (< 50% area), or extensive (≥ 50% area) on histological examination. The relationship between tumor necrosis, clinicopathologic characteristics, and long-term survival were analyzed. RESULTS: Among 919 patients who underwent curative-intent resection for HCC, the median tumor size was 5.0 cm (IQR, 3.0-8.5). Tumor necrosis was present in 367 (39.9%) patients (no necrosis: n = 552, 60.1% vs < 50% necrosis: n = 256, 27.9% vs ≥ 50% necrosis: n = 111, 12.1%). Extent of tumor necrosis was also associated with more advanced tumor characteristics. HCC necrosis was associated with OS (median OS: no necrosis, 84.0 months vs < 50% necrosis, 73.6 months vs ≥ 50% necrosis: 59.3 months; p < 0.001) and RFS (median RFS: no necrosis, 49.6 months vs < 50% necrosis, 38.3 months vs ≥ 50% necrosis: 26.5 months; p < 0.05). Patients with T1 tumors with extensive ≥ 50% necrosis had an OS comparable to patients with T2 tumors (median OS, 62.9 vs 61.8 months; p = 0.645). In addition, patients with T2 disease with necrosis had long-term outcomes comparable to patients with T3 disease (median OS, 61.8 vs 62.4 months; p = 0.713). CONCLUSION: Tumor necrosis was associated with worse OS and RFS, as well as T-category upstaging of patients. A modified AJCC T classification that incorporates tumor necrosis should be considered in prognostic stratification of HCC patients.
