HPB SO18 - Management of distal cholangiocarcinoma with arterial involvement: Systematic review and case series on the role of neoadjuvant therapy

Abstract Background The use of neoadjuvant therapy (NAT) in distal cholangiocarcinoma (dCCA) with regional arterial or extensive venous involvement, is not widely accepted and evidence is sparse. The aim of this study was synthesise evidence on NAT for dCCA and present the experience of a high-volume tertiary-centre managing dCCA with arterial involvement. Method A systematic review was performed according to PRISMA guidance to identify all studies reporting outcomes of patients with dCCA who received NAT. All patients from 2017 to 2022 who were referred for NAT for dCCA at our centre were retrospectively collected from a prospectively maintained database. Baseline characteristics, NAT type, progression to surgery and oncological outcomes were collected. Results Twelve studies were included. Definition of “unresectable” locally-advanced-dCCA was heterogenous. Four studies reported outcomes for 9 patients who received NAT for dCCA with vascular involvement. R0 rate ranged between 0 and 100% but without survival benefit in most cases. Remaining studies considered NAT in resectable dCCA or with extrahepatic-CCA. The case series includes 9 patients (median age 67, IQR 56-74 years, male:female 5:4) referred for NAT for borderline-resectable or locally-advanced disease. Three patients progressed to surgery and 2 were resected. One patient died at 14 months, and one died at 51 months. Both had recurrence 6 months post-operatively. Conclusion From our own series and included studies that report on NAT for dCCA with extensive vascular involvement, evidence for the benefit of NAT is limited. Consensus on the criteria for a uniform definition of resectability for dCCA is required, which will provide homogeneity in reporting of pathways and outcomes. We propose the use of the already established National Comprehensive Cancer Network® criteria for PDAC.

Numerical Analysis and Experimental Validation of Trimaran and Pentamaran Resistance at Various Separation Distances

Trimaran and pentamaran are multihull types with an odd number of hulls, namely three and five hulls, generally consisting of one center hull and two or four side hulls smaller than the center hull, which can reduce ship resistance. The trimaran and pentamaran have a more complex phenomenon than the monohull, because of the interaction between the main hull and the side hull, which causes interference caused by changes in flow velocity, pressure changes, and wave interactions generated by each hull. The objective of this study is to analyze the resistance of trimaran and pentamaran NPL-4b models with transom-symmetrical hull and separation distances, specifically S/L ratios of 0.2, 0.3, and 0.4. Since a more limited base of experience exists for multihull ships, experimental or numerical modeling techniques are essential for designers. Numeric investigations were conducted using Numeca software, and experiments were performed in a towing tank. Both methods follow ITTC procedures. Furthermore, the numerical analysis with CFD simulation modifies the Navier-Stokes equation using the turbulence model k-ꞷ SST to generate the RANS equation so that unsteady fluid flow problems can be calculated. It can be implemented in predicting resistance in Froude numbers (Fr) 0.2 to 0.6 at the systematic series of trimaran and pentamaran hull shapes at the model scale. The simulation results were compared to experimental data to validate the resistance of the ships. Overall, good resistance was produced by the trimaran and pentamaran in the C configuration at an S/L ratio of 0.4 with a total resistance coefficient CT of 6.60 x 10-3 and 7.37 x 10-3, respectively. The two results are in good agreement, both methods have a discrepancy of 3.70 %. Fluctuations influence the resistance in the wetted surface area (WSA), wave interactions between hulls, ship velocity, and wave propagation in the aft hull.

CFD-based analysis of deviations between thermocouple measurements and local gas temperatures during the cooling phase of compartment fires

Data from thermocouple (TC) measurements play a pivotal role in fire safety science and engineering studies. It is well-known that there are deviations from the actual local gas temperature and many studies have led to the development of correction factors. The present study focuses on these deviations inside compartments through a systematic series of CFD simulations, performed with Fire Dynamics Simulator (FDS), version 6.8.0. A canonical cubic box is used as geometry. This allows for the demonstration of the impact of the presence of smoke, with variable optical thickness, on the TC data as retrieved from FDS. Significant differences are observed between TC measurements and local gas temperatures. Corrections as developed for TC measurements in open atmospheres cannot be readily applied in compartment configurations, where smoke properties change both spatially and temporally.

The Quality of Embedding Charges Is Critical for Convergence of Many-Body Expansions When BSSE Is Absent.

There is conflicting evidence in the literature concerning the benefits of charge embedding on the convergence of many-body expansions (MBEs). Using a systematic series of water and ion-water clusters of varying size, this study indicates that the effects of charge embedding can be masked by basis set superposition error (BSSE). When BSSE is removed, this study demonstrates that charge embedding can significantly accelerate MBE convergence, where the electrostatically embedded two-body method, EE-MBE(2), can often yield accuracy close to the four-body method, MBE(4). Contrary to previous studies on smaller systems, this work shows that the performance of EE-MBE is highly sensitive to the charge model, with the best performance obtained when the natural population analysis (NPA) charge model is used and generated at the same level of theory used in the subsystem and supersystem calculations. It was demonstrated that the "3c" composite method, PBEh-3c, yields NPA atomic charges that are in excellent agreement with those obtained from supersystem density functional theory calculations. The linear-scaling X-Polarization method provides a more general approach to estimating these supersystem QM atomic charges, but its performance depends on how the fragments are defined.

The LAMB3-EGFR signaling pathway mediates synergistic Anti-Cancer effects of berberine and emodin in Pancreatic cancer

Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignancy, primarily due to the intrinsic development of chemoresistance. The most apparent histopathological feature associated with chemoresistance is the alterations in extracellular matrix (ECM) proteins. Natural dietary botanicals such as berberine (BBR) and emodin (EMO) have been shown to possess chemo-preventive potential by regulating ECM in various cancers. Herein, we further investigated the potential synergistic effects of BBR and EMO in enhancing anticancer efficacy by targeting ECM proteins in pancreatic cancer. Genomewide transcriptomic profiling identified that LAMB3 was significantly upregulated in PDAC tissue and highly associated with poor overall survival (OS, hazard ratio [HR], 2.99, 95 % confidence interval [CI], 1.46–6.15; p = 0.003) and progress-free survival (PFS, HR, 2.59; 95 % CI, 1.30–5.18; p = 0.007) in PDAC. A systematic series of functional experiments in BxPC-3 and MIA-PaCa-2 cells revealed that the combination of BBR and EMO exhibited synergistic anti-tumor potential, as demonstrated by cell proliferation, clonogenicity, migration, and invasion assays (p < 0.05–0.001). The combination also altered the expression of key proteins involved in apoptosis, EMT, and EGFR/ERK1,2/AKT signaling. These findings were further supported by patient-derived organoids (PDOs), where the combined treatment resulted in fewer and smaller organoids compared to each compound individually (p < 0.05–0.001). Our results suggest that BBR combined with EMO exerts synergistic anti-cancer effects by modulating the EGFR-signaling pathway through interference with LAMB3 in PDAC.

Management of distal cholangiocarcinoma with arterial involvement: Systematic review and case series on the role of neoadjuvant therapy.

The use of neoadjuvant therapy (NAT) in distal cholangiocarcinoma (dCCA) with regional arterial or extensive venous involvement, is not widely accepted and evidence is sparse. To synthesise evidence on NAT for dCCA and present the experience of a high-volume tertiary-centre managing dCCA with arterial involvement. A systematic review was performed according to PRISMA guidance to identify all studies reporting outcomes of patients with dCCA who received NAT. All patients from 2017 to 2022 who were referred for NAT for dCCA at our centre were retrospectively collected from a prospectively maintained database. Baseline characteristics, NAT type, progression to surgery and oncological outcomes were collected. Twelve studies were included. The definition of "unresectable" locally advanced dCCA was heterogenous. Four studies reported outcomes for 9 patients who received NAT for dCCA with extensive vascular involvement. R0 resection rate ranged between 0 and 100% but without survival benefit in most cases. Remaining studies considered either NAT in resectable dCCA or inclusive with extrahepatic CCA. The presented case series includes 9 patients (median age 67, IQR 56-74 years, male:female 5:4) referred for NAT for borderline resectable or locally advanced disease. Three patients progressed to surgery and 2 were resected. One patient died at 14 months with evidence of recurrence at 6 months and the other died at 51 months following recurrence 6 months post-operatively. Evidence for benefit of NAT is limited. Consensus on criteria for uniform definition of resectability for dCCA is required. We propose using the established National-Comprehensive-Cancer-Network® criteria for pancreatic ductal adenocarcinoma.

The Use of Immunomodulators, Biologic Therapies, and Small Molecules in Patients With Inflammatory Bowel Disease and Solid Organ Transplant.

Patients with inflammatory bowel diseases (IBDs) may require solid organ transplants (SOTs) for multiple reasons, making its prevalence slightly higher than the general population. Although immunosuppression used in SOT may help control IBD-related inflammation, many patients still require additional immunosuppressive medications. We aim to assess the effectiveness and safety of the combination of SOT-related immunosuppression and IBD medications in patients with liver, kidney, or heart transplantation. We conducted a clinical review using PubMed, Scopus, MEDLINE, Embase, and Google Scholar databases for our search. We included data from systematic reviews, meta-analyses, case series, and case reports to assess the safety, effectiveness, and side effect profile of immunomodulators, biologic therapies, and small molecules in patients with SOT. Our review encompassed 25 liver, 6 kidney, and 1 heart transplant studies involving patients with IBD. Common liver transplant immunosuppressants included tacrolimus, mycophenolate mofetil, cyclosporine, and steroids. Anti-TNF agents, widely used in all SOT types, showed no significant safety issues, though infections and malignancies were noted. Patients with liver transplant on tacrolimus responded well to anti-integrins and ustekinumab without major complications. For kidney transplants, cyclosporine and tacrolimus were prevalent, and their combination with anti-TNF or ustekinumab was generally safe, with rare reports of malignancy or infection. Hence, the use of anti-TNF, anti-integrin agents, and ustekinumab appears to be safe in patients with SOT, regardless of their transplant related immunosuppression. More studies are needed in patients with kidney and heart transplants and in patients treated with small molecules for their IBD.

Bridging the Gap between Laboratory and Industrial Scale Electrochemical Characterisation of Raney Ni Electrodes for Alkaline Water Electrolysis

The most mature water electrolysis technology is alkaline electrolysis, where an aqueous solution of KOH is used as the electrolyte. While this technology has been used for decades, there is still a lot of potential to improve the performance of these devices. Much research is focused on the optimisation of the electrodes containing novel catalyst materials that lower the activation energy barrier of the electrolysis process. However, one of the issues described by Ehlers et al.1 is that the current academic electrolysis research is done under conditions that are far from practical (e.g. at low current densities, room temperature, and dilute electrolytes).In this study, we characterise a commercial Raney nickel electrode in various setups using a systematic series of experiments, including a typical laboratory-scale three-electrode setup, two different flow-cell setups and a 10-kW electrolysis stack of 17 cells. In addition to the cell geometry (electrode area ranging from 1 cm2 to 960 cm2), the varied measurement conditions include temperature (ranging from room temperature to 80 degrees Celsius), pressure (from atmospheric pressure to ), electrolyte concentration (from 0.1 M to 30 wt% KOH), and the level of Fe impurities in the electrolyte. The resulting electrochemical data received from different measurement setups and measurement conditions are compared, and insights about the challenges related to correlating laboratory experiments to industrial-scale experiments are provided. Figure 1.

The giant graviton expansion

We propose and test a novel conjectural relation satisfied by the superconformal index of maximally supersymmetric U(N) gauge theory in four dimensions. Analogous relations appear to be also valid for the superconformal indices of a large collection of other gauge theories, as well as for a broad class of index-like generating functions. The relation expresses the finite N index as a systematic series of corrections to a large N answer. Individual corrections have an holographic interpretation as the analytic continuation of contributions from “giant graviton” branes fixed by a specific symmetry generator.

THE SACRED SIGNIFICANCE OF LOCAL WISDOM IN THE BASAPA RITUAL OF MINANGKABAU

The extraordinary enthusiasm of the people attending the Basapa tradition event was generally reasonable because they respected those who had contributed to spreading Islam in Minangkabau and again there were several sacred things attached to Sheikh Burhanuddin so that it became an attraction for pilgrims to attend the rituals carried out every year in the month of Safar. Basapa is a ritual in the form of a simultaneous pilgrimage at the tomb of Sheikh Burhanuddin in Ulakan. Although the cleric figure of Sheikh Burhanuddin of the Tariqa Syattariah congregation, at the Basapa event, those who attended were not only followers of the Syattariah congregation but also the Muslim community in general. The formulation of the problem, namely: What is the background of the development and procession of the Basapa ritual in Ulakan and why the Basapa ritual became sacred in Ulakan, so that it was attended by many people in general from various parts outside the province of West Sumatra. This type of research is included in qualitative descriptive research, as for the systematic series of this research, namely: data sources, data collection techniques and data processing and analysis techniques. The result of the research is that mass pilgrimages occur at the Basapa Ritual which is considered sacred to its followers. The resultant attractive-consolidative Basapa ritual provides reconciliation from various socio-cultural aspects, especially giving the value of cultural inclusiveness to Minangkabau Islam and the sacredness of local wisdom or local wisdom from the Basapa tradition initially based on a religious dimension, but in its improvement, it became a local convention which in the end became a single ethnic identity.

Synergistic Catalytic Effects on Nitrogen Transformation during Biomass Pyrolysis: A Focus on Proline as a Model Compound.

To investigate the control mechanisms of NOx precursors and the synergistic effects of composite catalysts during proline pyrolysis, a systematic series of experiments was conducted utilizing composite catalysts with varying Fe-Ca ratios. Product distribution analysis was employed to elucidate the catalysts' mechanisms in reducing NOx precursor emissions. The synergistic interactions between Fe and Ca were quantitatively assessed through comparative theoretical and experimental release calculations. The results indicate that an increase in the Fe content in the catalyst led to a rise in amine concentrations from 0.9% to 2.95%, implying that Fe facilitates the generation of amine-N through ring-opening and substitution reactions. When the Fe to Ca ratio was balanced at 1:1, nitrogen predominantly participated in the formation of purines via cyclization and substitution reactions. Additionally, all composite catalysts exhibited a suppressive effect on the release of NOx precursors, attributed to their significant enhancement of solid product retention. Fe-Ca composite catalyst synergistically inhibits the release of gaseous nitrogen. Notably, the strongest synergistic effect was observed with a 1:3 Fe to Ca ratio, which reduced the release of NH3 by 38.7% and HCN by 53.6% during proline pyrolysis. This study offers valuable insights into the control of NOx precursors and the optimization of nitrogen-rich biomass pyrolysis processes.

Inline monitoring of lactobionic acid production from cheese whey by Pseudomonas taetrolens in a stirred bioreactor using electrical conductivity

AbstractIn this study, we introduce a novel experimental approach and present a simplified mathematical model for a quick monitoring of a biotec process producing lactobionic acid (LBA). It relies on monitoring the electrical conductivity of the fermentation broth and it is designed to predict the concentration of LBA throughout the microbial cheese whey valorization via LBA production. Following a systematic series of experiments conducted to refine the mathematical model, we performed conductivity monitoring during LBA production from “caciotta” and “squacquerone” wheys by Pseudomonas taetrolens in a 3 L stirred tank bioreactor. Throughout the bioproduction process, the conductivity values exhibited an upward trend corresponding to the increase in LBA concentration. Our findings underscore the feasibility and advantages of employing inline conductivity monitoring during LBA production from various cheese wheys. The results emphasize that conductivity measurements can effectively estimate product concentration in a fermentation process, particularly when there is a shift in ionic concentration. Furthermore, these conductivity measurements offer valuable insights for monitoring and optimizing the working conditions in a fermentation process.

Economic Analysis of Cochlear Implants in Adults With Bilateral Severe-to-Profound Hearing Loss. A Systematic Review of the Literature.

To determine the cost-effectiveness or cost-utility of cochlear implants (CI) in adults with severe to profound bilateral hearing loss. PubMed (Medline), The Cochrane Library, Embase via Elsevier, EBSCOhost CINAHL, and Scopus. The study included adult participants with severe to profound bilateral neurosensory hearing loss. The analysis encompassed quality of life improvements, costs, cost-effectiveness, cost-utility, cost-benefit, quality-adjusted life year (QALY), incremental cost-effectiveness ratio (ICER), and incremental cost-utility ratio (ICUR). Systematic reviews, meta-analyses, case series, and prospective or retrospective cohort studies published in English between 2010 and 2023 were retrieved. Exclusion criteria included incomplete studies, abstracts, clinical cases, editorials, letters, studies involving pediatric populations, single-side deafness, methodology research, noneconomic aspects of CI, mixed child and adult data, and studies published before 2010. The risk of bias was assessed following the criteria outlined in Appendix I of the economic evaluation's quality assessment as per the NICE Guideline Development Method. Ten articles met the criteria and were included in the qualitative synthesis. One study conducted a prospective cost-utility analyses, one carried out a cost-benefit analyses, one was a randomized controlled clinical trial focusing on cost-utility, and another was a clinical trial addressing cost-effectiveness. Six studies employed Markov models, and one study utilized uniquely the Monte Carlo method. None quantified the economic impact of improved hearing on cognitive function. The heterogeneity of sources impacted data quality. Unilateral and sequential bilateral CI appeared to be cost-effective when compared with bilateral hearing aids or nontechnological support. When properly indicated, simultaneous bilateral CIs are cost-effective compared to no interventions and to unilateral cochlear implantation through differential discounting or variations from the base cases, especially with a life expectancy of 5-10 years or longer.

Adsorber Charge Dominates over Hydrophobic or Fluorophilic Functionalization in Influencing Adsorption of PFCA onto Polystyrene Resins

AbstractA systematic series of industrial‐relevant polystyrene‐based anion exchange resins that are functionalized with hydro‐ or fluorocarbon chains are compared regarding their adsorption behavior toward perfluorocarboxylic acids (PFCA) in respect to their charge, chain length, and type of chain. The results clearly show the dominance of electrostatic interactions in the adsorption process as uncharged adsorber materials showed no adsorption at all. In contrast, the charged adsorber materials showed in general a PFCA removal of 80% to 30% over the experiment depending on effluent fraction. Unexpectedly, for perfluorobutanoic acid (PFBA) the highest removal rate is found with consistently &gt;90%. Despite observing significant benefits in the adsorption of PFCA for fluoroalkylated adsorbers in comparison to their non‐fluorinated counterparts, this effect of fluoroalkylation is comparatively small and can not be clearly attributed to fluorophilic interactions between the fluoroalkyl chains. These findings help clarifying that the introduction of fluorocarbon moieties in adsorber materials is not necessary in order to remove fluorocarbon molecules from the environment.

Effects of Combination of Curcumin and Piperine Supplementation on Glycemic Profile in Patients with Prediabetes and Type 2 Diabetes Mellitus: A Systematic Review and Meta-analysis.

This study aimed to evaluate the effects of the combination of curcumin and piperine supplementation on Fasting Plasma Glucose (FPG), Homeostatic Model of Insulin Resistance (HOMA-IR), and Body Mass Index (BMI) in patients with prediabetes and type 2 Diabetes Mellitus (T2DM). This review was done to identify potential herbal remedies that may help improve glycemic parameters, leading to better health outcomes in combination with current antidiabetic treatment. This systematic review was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). It was conducted in 2023 with sources and databases from MEDLINE, EBSCO-Host, ScienceDirect and ProQuest. This paper included randomized-controlled trials exploring the effects of the combination of curcumin and piperine on patients with prediabetes and T2DM. Systematic reviews, observational studies, case reports, case series, conference abstracts, book sections, commentaries/editorials, non-human studies and articles with unavailable full-text and written in non-English language, were excluded. The key terms for the literature search were "curcumin," "piperine," "prediabetes" and "Type 2 Diabetes Mellitus." We use Cochrane Risk of Bias (RoB) 2 for quality assessment of the included studies and Review Manager (RevMan) 5.4 to do the meta-analysis. A total of three studies were included in this systematic review. Two studies from Neta et al., and Cicero et al., showed no significant difference in HOMA-IR, BMI and FPG levels between the curcumin, piperine and placebo groups. One study from Panahi et al. demonstrated a significant difference in BMI levels between the curcumin and piperine and placebo groups (p <0.01). The meta-analysis showed that FPG levels, HOMA-IR and BMI improved among patients with diabetes given in curcumin and piperine with reported mean differences (MD) of = -7.61, 95% CI [-15.26, 0.03], p = 0.05, MD = -0.36, 95% CI [-0.77 to 0.05], p = 0.09, and MD = -0.41, 95% CI [-0.85 to 0.03], p = 0.07, respectively). The supplementation of curcumin and piperine showed a numerical reduction in FPG, HOMA-IR and BMI, but were not statistically significant. Further research is needed as there is a paucity of studies included in the review.

Systematic KMTNet Planetary Anomaly Search. XI. Complete Sample of 2016 Subprime Field Planets

Following Shin et al. (2023b), which is a part of the “Systematic KMTNet Planetary Anomaly Search” series (i.e., a search for planets in the 2016 KMTNet prime fields), we conduct a systematic search of the 2016 KMTNet subprime fields using a semi-machine-based algorithm to identify hidden anomalous events missed by the conventional by-eye search. We find four new planets and seven planet candidates that were buried in the KMTNet archive. The new planets are OGLE-2016-BLG-1598Lb, OGLE-2016-BLG-1800Lb, MOA-2016-BLG-526Lb, and KMT-2016-BLG-2321Lb, which show typical properties of microlensing planets, i.e., giant planets orbit M-dwarf host stars beyond their snow lines. For the planet candidates, we find planet/binary or 2L1S/1L2S degeneracies, which are an obstacle to firmly claiming planet detections. By combining the results of Shin et al. (2023b) and this work, we find a total of nine hidden planets, which is about half the number of planets discovered by eye in 2016. With this work, we have met the goal of the systematic search series for 2016, which is to build a complete microlensing planet sample. We also show that our systematic searches significantly contribute to completing the planet sample, especially for planet/host mass ratios smaller than 10−3, which were incomplete in previous by-eye searches of the KMTNet archive.

Exploring Innovative Applications of Evaporative Cooling for High-Total-Dissolved-Solids Produced-Water Treatment

Summary This research delves into the pioneering application of evaporative cooling (EC) to address the challenge of reducing total dissolved solids (TDS) in produced water generated during hydraulic fracturing operations in the Permian Basin. In this study, we used a meticulously designed laboratory-scale EC system comprising three cooling pads, a fan, a water reservoir, and a pump. Through a systematic series of experiments, both synthetic and authentic produced-water samples were treated, shedding light on the potential of this novel approach. The EC system efficiently processed untreated produced water, circulating it through the cooling pads, all while closely monitoring crucial variables such as inlet and outlet temperatures, relative humidity, and remaining water volume, utilizing a state-of-the-art temperature and humidity meter. Control experiments were systematically conducted to probe the influence of varying salinities, achieved by introducing NaCl into distilled water, encompassing a wide range from 0 ppm to 70,000 ppm. In addition, we extended our evaluation to real produced-water samples collected from diverse regions within the Permian Basin (Delaware, Northern Midland, and Southern Midland), reflecting the system’s capability to manage high salinity and the diverse impurities inherent to oil and gas production. A comparative analysis of energy consumption was undertaken, positioning EC against conventional thermal evaporation techniques. The findings revealed a compelling insight that differences in EC efficiency between synthetic and real oilfield brines were primarily attributed to the presence of sodium (Na+) and chlorine (Cl-) contents rather than the overall TDS concentration. Across all experiments, the system consistently achieved remarkable TDS removal efficiencies, hovering around the 100% mark for both synthetic and authentic produced-water samples. Moreover, the study unveiled a significant advantage of EC, as it proved to be significantly less energy-intensive when juxtaposed with conventional thermal evaporation methods. In addition, our experiments revealed that divalent ions like CaCl2 tend to lower the treatment efficiency compared to monovalent ions, adding a crucial dimension to our understanding of EC in water treatment. The EC system demonstrated remarkable efficiency, achieving nearly 100% TDS removal in both synthetic and real samples while being significantly less energy-intensive than conventional thermal evaporation methods. This research underscores EC’s potential as an effective, sustainable, and economical solution for high-TDS water treatment, with promising applications in industrial settings. The study also draws parallels between EC and air conditioning systems, suggesting its versatility in various industrial applications.
