RESUMO

INTRODUCTION: Intrahepatic and extrahepatic lithiasis, a condition characterized by the presence of stones in the liver and bile ducts, is a common disease in Asia, particularly in East and Southeast Asia. We report a case with laparoscopic exploration of the common bile duct using a flexible cholangioscope and modified trans-common bile duct tunnel for hepatolithiasis combined with the dilated common bile duct. PRESENTATION OF CASE: A 35-year-old male patient has had chronic epigastric and right upper quadrant pain. The common bile duct was 11 mm dilated, and hepatolithiasis was also present, according to an upper abdomen MRI. The largest stone measured between 14 and 21 mm. A modified trans-common bile duct tunnel from the abdominal wall into the common bile duct was used in a laparoscopic procedure to examine the common bile duct. Complications during the procedure or following it were not present. The procedure took 120 min, and the blood loss was about 50 ml. The patient was discharged on the sixth postoperative day, and a follow-up visit one month later revealed that single-session stone clearance had been accomplished. DISCUSSION: Laparoscopic exploration of the common bile duct using a cholangioscope and modified trans-choledochal tube is applicable in selected patients and can be effectively and safely used to treat hepatolithiasis combined with the dilated common bile duct. CONCLUSION: In this case, we present an innovative approach for hepatolithiasis when combined with dilated common bile duct.

RESUMO

BACKGROUND: Our study aims to evaluate the biliary anatomy variation according to the Varotti classification and its correlation with surgical outcomes for both donors and recipients undergoing living donor liver transplants (LDLTs). METHODS: A retrospective analysis of 150 LDLT cases performed at a single center in Vietnam with preoperative radiologic evaluations and intraoperative surgical assessments to identify biliary variant anatomy. Postoperative biliary complications were documented and analyzed. Statistical analysis was performed to determine any significant associations between biliary variations and post-transplant outcomes. RESULTS: One hundred fifty cases of LDLT at 108 Military Central Hospital from October 2017 to December 2022 were included in our study. Among the donors, the mean age was 30.89 ± 7.23, with male predominance (77.3%). The prevalence of type 1 biliary anatomy was 84.67%. Type 2, 3a, 3b, 4a, and 4b accounted for 5.33%, 2.67%, 5.33%, 0.67%, and 1.33% of cases, respectively. Donors' complications were witnessed in 7 cases (4.67%), and all needed intervention (Clavien-Dindo grade 3). Biliary complications were found in 36 (24.0%) recipients, with 22 (14.67%) cases of biliary stenosis and 16 (10.67%) cases of biliary leak, including 2 cases encountering both complications. Age, gender, graft type, preoperative liver function, biliary variant anatomy, number of graft orifices, Model for End-Stage Liver Disease score, and blood loss were not significant risk factors for recipients' biliary complications. Cold ischemia time significantly increased the biliary complication rate. CONCLUSIONS: This study shows that biliary variant anatomy is common in living liver donors. Such variations should not be a contraindication to liver donation. However, accurate pre- and intraoperative radiologic and surgical evaluations are fundamental for a careful reconstruction plan.

RESUMO

The search for chemical hit material is a lengthy and increasingly expensive drug discovery process. To improve it, ligand-based quantitative structure-activity relationship models have been broadly applied to optimize primary and secondary compound properties. Although these models can be deployed as early as the stage of molecule design, they have a limited applicability domain─if the structures of interest differ substantially from the chemical space on which the model was trained, a reliable prediction will not be possible. Image-informed ligand-based models partly solve this shortcoming by focusing on the phenotype of a cell caused by small molecules, rather than on their structure. While this enables chemical diversity expansion, it limits the application to compounds physically available and imaged. Here, we employ an active learning approach to capitalize on both of these methods' strengths and boost the model performance of a mitochondrial toxicity assay (Glu/Gal). Specifically, we used a phenotypic Cell Painting screen to build a chemistry-independent model and adopted the results as the main factor in selecting compounds for experimental testing. With the additional Glu/Gal annotation for selected compounds we were able to dramatically improve the chemistry-informed ligand-based model with respect to the increased recognition of compounds from a 10% broader chemical space.

RESUMO

Introduction: The Vietnamese Home Falls and Accidents Screening Tool (HOME FAST) was developed to measure the number of home hazards present in the homes of older Vietnamese people and the risk of falls. Methods: The HOME FAST and the HOME FAST manual were translated into Vietnamese by an independent translator and underwent backward translation by local health professionals into English to evaluate the accuracy of the translation. A panel of 14 Vietnamese health professionals evaluated the validity of the HOME FAST translation and rated the clarity and cultural relevance of each item. Ratings were evaluated using the content validity index (CVI). Reliability in ratings of the HOME FAST was evaluated using intra-class correlations (ICC), and ratings took place within the homes of two older Vietnamese people by six assessors. Results: In all, 22 out of 25 Vietnamese HOME FAST items were considered to have met content validity standards using the CVI. The ICC for home visit one was 0.94 (95% CI 0.87-0.97) and for home visit two was ICC 0.95 (95% CI 0.91-0.98) indicating high reliability. Discussion and conclusion: Bathroom items showed the most inconsistency in ratings indicating cultural differences in bathing activities. Descriptors of HOME FAST items will be reviewed for use in Vietnam to account for cultural and environmental differences. A larger pilot study is planned with older people living in the community in Vietnam to include calendar ascertainment of falls to determine if home hazards are associated with falling.

RESUMO

Evaluating the results of laparoscopic cholecystectomy (LC) using indocyanine green (ICG) fluorescence. Materials and methods: This is a cross-sectional study of patients with LC using real-time fluorescent ICG to treat gallbladder disease from May 2021 to May 2022 in the 108 Military Central Hospital. Results: There were 68 patients who underwent LC using intraoperative ICG fluorescence for bile duct visualization. The mean age of the patients was 55.4±16.2, and the male/female ratio was 1.52. Chronic cholecystitis caused by stones accounted for the majority (51.47%). The authors detected 7.35% of cases with anatomical changes of the extrahepatic biliary tract using ICG fluorescence and clearly identified the anatomy of the common bile duct and the cystic duct at 100 and 92.65%, respectively. The average surgical time was 42.8±14.6 min. There were no postoperative complications or side effects from ICG; the average hospital stay was 2.8±1.5 days. Conclusions: ICG fluorescence cholangiography allows surgeons to easily identify critical anatomical landmarks in the LC. Thereby helping the surgery to be performed safely, avoiding severe complications due to damage to the biliary tract.

RESUMO

Problem: Like most low- and middle-income countries, Viet Nam has a scarcity of rehabilitation professionals and lacks training programmes that meet international standards. Approach: In 2018, four Vietnamese medical universities, the Université Catholique de Louvain, the Université Libre de Bruxelles, the Humanity & Inclusion charity and World Physiotherapy agreed to collaborate on strengthening pre-service education for physiotherapists in the country. Local setting: Viet Nam has a favourable environment for nurturing rehabilitation services and education: development funds have been available; government investment is increasing; and rehabilitation education has existed for many decades. Relevant changes: The collaboration resulted in the establishment of: (i) a 4-year, competency-based, entry-level curriculum for physiotherapists (bachelor's degree); (ii) opportunities for continuing professional development; (iii) a 2-year master's programme for physiotherapy lecturers and clinical supervisors; and (iv) a national physiotherapy association. In addition, four students were supported in studying for PhD degrees. Strong collaboration and comprehensive and complementary interventions have laid the foundations for sustainable, high-quality, educational programmes for physiotherapists, which will improve access to, and the standard of, rehabilitation services in Viet Nam, thereby leading to better patient outcomes. Lessons learnt: Curricula for entry-level physiotherapy programmes should be competency-based, be actively managed by national educators and meet international standards while being responsive to local priorities. To strengthen the rehabilitation workforce, educators involved in teaching and supervising training programmes should have the skills and knowledge required. A national professional physiotherapy association should be established to provide continuing professional development for physiotherapists and to take part in international collaborations.

RESUMO

Candida albicans is an opportunistic pathogen involved in many infections, especially linked to implanted medical devices. Its ability to form biofilms complicates the treatment of these infections as few molecules are active against sessile C. albicans. The aim of this study was to evaluate the potential of leaves, three-month-old and one-year-old stems of Rubus idaeus L. against C. albicans biofilm growth. Extractions with a polarity gradient were carried out on hydroacetonic extracts and followed by fractionation steps. The obtained extracts and fractions were tested for their anti-biofilm growth activity against C. albicans using XTT method. Compounds of active subfractions were identified by LC-MS. The hexane extracts from leaves and stems were the most active against the fungus with IC50 at 500 and 250 µg/mL. Their bioguided fractionation led to 4 subfractions with IC50 between 62.5 and 125 µg/mL. Most of the components identified in active subfractions were fatty acids and terpenoïds.

RESUMO

Artificial intelligence (AI) is undergoing a revolution thanks to the breakthroughs of machine learning algorithms in computer vision, speech recognition, natural language processing and generative modelling. Recent works on publicly available pharmaceutical data showed that AI methods are highly promising for Drug Target prediction. However, the quality of public data might be different than that of industry data due to different labs reporting measurements, different measurement techniques, fewer samples and less diverse and specialized assays. As part of a European funded project (ExCAPE), that brought together expertise from pharmaceutical industry, machine learning, and high-performance computing, we investigated how well machine learning models obtained from public data can be transferred to internal pharmaceutical industry data. Our results show that machine learning models trained on public data can indeed maintain their predictive power to a large degree when applied to industry data. Moreover, we observed that deep learning derived machine learning models outperformed comparable models, which were trained by other machine learning algorithms, when applied to internal pharmaceutical company datasets. To our knowledge, this is the first large-scale study evaluating the potential of machine learning and especially deep learning directly at the level of industry-scale settings and moreover investigating the transferability of publicly learned target prediction models towards industrial bioactivity prediction pipelines.

RESUMO

MOTIVATION: Subtyping cancer is key to an improved and more personalized prognosis/treatment. The increasing availability of tumor related molecular data provides the opportunity to identify molecular subtypes in a data-driven way. Molecular subtypes are defined as groups of samples that have a similar molecular mechanism at the origin of the carcinogenesis. The molecular mechanisms are reflected by subtype-specific mutational and expression features. Data-driven subtyping is a complex problem as subtyping and identifying the molecular mechanisms that drive carcinogenesis are confounded problems. Many current integrative subtyping methods use global mutational and/or expression tumor profiles to group tumor samples in subtypes but do not explicitly extract the subtype-specific features. We therefore present a method that solves both tasks of subtyping and identification of subtype-specific features simultaneously. Hereto our method integrates` mutational and expression data while taking into account the clonal properties of carcinogenesis. Key to our method is a formalization of the problem as a rank matrix factorization of ranked data that approaches the subtyping problem as multi-view bi-clustering RESULTS: We introduce a novel integrative framework to identify subtypes by combining mutational and expression features. The incomparable measurement data is integrated by transformation into ranked data and subtypes are defined as multi-view bi-clusters We formalize the model using rank matrix factorization, resulting in the SRF algorithm. Experiments on simulated data and the TCGA breast cancer data demonstrate that SRF is able to capture subtle differences that existing methods may miss. AVAILABILITY AND IMPLEMENTATION: The implementation is available at: https://github.com/rankmatrixfactorisation/SRF CONTACT: kathleen.marchal@intec.ugent.be, siegfried.nijssen@cs.kuleuven.be SUPPLEMENTARY INFORMATION: Supplementary data are available at Bioinformatics online.

RESUMO

Studies of 805 samples until 10/2004 show that the malaria prevalence was high in the first 5 months in 2003, among 7 deaths were unorganized migrants. They contract malaria all year round, especially in the beginning of the year with the highest of 11.96% in February. The density of maralia parasite (+) was high in months at the beginning and end of the year such as January, April and October with the density in the first month of 2.92%. Spleenomegaly was mostly seen in age 5-14 with 3.17% and mostly in grade I and II (97.8%). Spleenomegaly grade III and IV is predominated in over 14 years old group (60%). Vectors at the first three months of the year were high and various in species in accordance with the malaria prevalence. An. dirus and An. minimus as the two main vectors of transmitting were present in almost of the year both house inside and outside, which is the cause for the transmission
