Outcomes after transcatheter mitral valve implantation in valve-in-valve, valve-in-ring, and valve-in-mitral annular calcification.

We aimed to evaluate transcatheter mitral valve implantation (TMVI) using predominantly balloon-expandable transcatheter heart valves (THV) in patients with a landing zone for a percutaneously delivered prosthesis. Patients with a degenerated mitral valve bioprosthesis, annuloplasty ring, and mitral annulus calcification (MAC) considered at high surgical risk currently represent a treatment challenge. TMVI is an alternative treatment option. Retrospective analysis of patients with symptomatic degenerated mitral valve bioprosthesis, or annuloplasty ring, and MAC treated with TMVI between November 2011 and April 2021. Endpoints were defined according to Mitral Valve Academic Research Consortium (MVARC) criteria and included device and procedure success at 30 days as well as mortality at 30 days and 1 year after the procedure. A total of 77 patients underwent TMVI (valve in valve [ViV = 56], valve in ring [ViR = 11], and valve in MAC [ViMAC = 10]). There was a trend toward higher technical success (all = 93.5%, ViV = 96.4%, ViR = 90.9%, ViMAC = 80%, p = 0.06) and lower 30-day (all = 11.7%, ViV = 10.7%, ViR = 9.1%, ViMAC = 20%, p = 0.49) and 1-year mortality (all = 26%, ViV = 23.2%, ViR = 27.3%, ViMAC= 40%, p = 0.36) after ViV and ViR compared to ViMAC. TMVI represents a reasonable treatment option in selected patients with MAC or who are poor candidates for redo mitral valve surgery. Technical success and survival up to 1 year were not significantly dependent on the subgroup in which TMVI was performed.

Treatment Response With Potassium-competitive Acid Blockers Based on Clinical Phenotypes of Gastroesophageal Reflux Disease: A Systematic Literature Review and Meta-analysis.

Gastroesophageal reflux disease (GERD) is typically managed based on the clinical phenotype. We evaluated the efficacy and safety of potassium-competitive acid blockers (PCABs) in patients with various clinical GERD phenotypes. Core databases were searched for studies comparing PCABs and proton pump inhibitors (PPIs) in clinical GERD phenotypes of erosive reflux disease (ERD), non-erosive reflux disease (NERD), PPI-resistant GERD and night-time heartburn. Additional analysis was performed based on disease severity and drug dosage, and pooled efficacy was calculated. In 9 randomized controlled trials (RCTs) evaluating the initial treatment of ERD, the risk ratio for healing with PCABs versus PPIs was 1.09 (95% CI, 1.04-1.13) at 2 weeks and 1.03 (95% CI, 1.00-1.07) at 8 weeks, respectively. PCABs exhibited a significant increase in both initial and sustained healing of ERD compared to PPIs in RCTs, driven particularly in severe ERD (Los Angeles grade C/D). In 3 NERD RCTs, PCAB was superior to placebo in proportion of days without heartburn. Observational studies on PPI-resistant symptomatic GERD reported symptom frequency improvement in 86.3% of patients, while 90.7% showed improvement in PPIresistant ERD across 5 observational studies. Two RCTs for night-time heartburn had different endpoints, limiting meta-analysis. Pronounced hypergastrinemia was observed in patients treated with PCABs. Compared to PPIs, PCABs have superior efficacy and faster therapeutic effect in the initial and maintenance therapy of ERD, particularly severe ERD. While PCABs may be an alternative treatment option in NERD and PPI-resistant GERD, findings were inconclusive in patients with night-time heartburn.

The Efficacy of the Cognitive Exercise Therapy Approach by Telerehabilitation in People Living with HIV: Preliminary Results.

The Cognitive Exercise Therapy Approach, referred to as BETY, is a biopsychosocial model that has demonstrated effectiveness in improving the quality of life among various patient populations with chronic diseases. This study aimed to determine the efficacy of BETY combined with telerehabilitation for people living with HIV (PLWH). Fifty PLWH who were virologically suppressed receiving follow-up and treatment at Şanlıurfa Training and Research Hospital were included in this study. Patients were divided into the telerehabilitation group (TG) and the control group (CG). In addition to routine treatments, the TG underwent group rehabilitation exercises via Zoom application for 60 minutes three times a week for 12 weeks (a total of 36 sessions) under the supervision of a physiotherapist, following the principles of BETY. The CG received no intervention and continued with routine medication treatments. Before and after the exercise therapy, the BETY Scale (BETY-BQ), Short Form-36 (SF-36), Hospital Anxiety and Depression Scale (HADS), Clinical Frailty Scale, and Frail Scale were administered to both the TG and the CG. The responses to the scales were compared between the two groups after the 12-week period. The preliminary results included data from 10 patients in the TG and 15 patients in the CG who completed the 12-week treatment. In the TG, significant differences were observed in the SF-36 pain subscale and the BETY total score, while in the CG, significant differences were found in the SF-36 emotional role functioning and vitality subscales (p<0.05). In the TG, negative values were observed in all BETY-BQ subscales, indicating improvement in all parameters. Additionally, the mean value of the SF-36 pain subscale increased from 79 before treatment to 91.5 after treatment. Our preliminary results indicate that the BETY method applied by telerehabilitation may be effective in reducing pain and improving biopsychosocial conditions in PLWH. Telerehabilitation with cognitive exercise therapy can provide an alternative treatment option by complementing routine therapies and offering the opportunity to participate anonymously in group therapies in PLWH.

Current state of endovascular treatment of anterior cerebral artery aneurysms.

The locations of anterior cerebral artery (ACA) aneurysms vary, and various aneurysms can occur along the course of the ACA. Ruptured and some unruptured ACA aneurysms may require aggressive treatment to avoid bleeding or rebleeding. Although open surgery is an effective treatment for ACA aneurysms, endovascular treatment (EVT) is becoming an alternative treatment in select cases. EVT techniques for ACA aneurysms often vary and are performed on a case-by-case basis according to the nature and location of the aneurysm. To better understand the EVT strategy for ACA aneurysms, it is necessary to review EVT for ACA aneurysms. In this review, the following topics are discussed: ACA anatomy and anomalies, classifications of ACA aneurysms, the natural history of ACA aneurysms, open surgery and EVT statuses for ACA aneurysms, EVT techniques for various ACA aneurysms, and the prognosis and complications of EVT for ACA aneurysms. According to our review and experience, traditional coiling EVT is still the preferred therapy for most ACA aneurysms. For A1 aneurysms, EVT is challenging. After the selection of appropriate cases, deployment of a flow diverter and Woven EndoBridge device can result in a good prognosis for patients with ACA aneurysms. In addition, parent artery occlusion can be used to treat A1 aneurysms with good collateral circulation and some distal ACA aneurysms. In general, EVT is gaining popularity as an alternative treatment option for ACA aneurysms.

Current Clinical Evidence for Magnetic Sphincter Augmentation: A Scoping Review

Background: Magnetic sphincter augmentation (MSA) is an alternative treatment option to laparoscopic fundoplication (LF) for patients with gastroesophageal reflux disease. To date, over 40,000 devices have been implanted worldwide since first approval in Europe in 2010 and the USA in 2012. Despite this clinical reality, the long-term safety and effectiveness of the procedure continues to be questioned. This study aims to systematically summarize and appraise the currently available evidence for MSA relative to effectiveness, safety, and healthcare resource use. Methods: A systematic literature search was carried out to identify all clinical studies published in English, as of February 15, 2023. Required endpoints were safety, effectiveness, and cost effectiveness. Results: The systematic search identified 212 publications and 14 entries in study registries. After screening and full text analysis, 82 publications were included in qualitative synthesis. One RCT established superiority of MSA compared to twice daily proton-pump inhibitors with respect to the elimination of moderate to severe regurgitation (89% vs 10%, RR 0.11, 95% CI 0.06-0.20, P &lt; 0.001). Eleven cohort studies comparing MSA to LF showed no statistical difference in safety profile and effectiveness measured by post-operative GERD-HRQL score. In addition, patients undergoing MSA significantly retained the ability to belch and vomit when compared to LF. These results were consistent in follow-up out to 7 years. Conclusions: LINX has been shown to provide long lasting relief to patients suffering from persistent GERD while maintaining an acceptable safety profile. As an outpatient day-procedure, MSA is cost effective with short recovery.

Therapeutic Phage Candidates for Targeting Prevalent Sequence Types of Carbapenem-Resistant Escherichia coli.

Carbapenem-resistant Escherichia coli (CREC) is a global threat to public health; therefore, alternative treatment options are urgently needed. Bacteriophages have emerged as promising candidates for combating CREC infections. This study aimed to investigate the genetic basis of phage sensitivity in CREC by evaluating carbapenem resistance among multidrug-resistant (MDR) E. coli isolated in Daegu, South Korea and analyzing their sequence types (STs) with phage susceptibility spectra. Among the 60 MDR E. coli isolates, 80.4% were identified as CREC, with 77.0% demonstrating resistance to imipenem and 66.6% to meropenem. Moreover, 70 lytic E. coli bacteriophages were isolated from hospital sewage water and evaluated against those 60 E. coli isolates. The phages exhibited lytic activity of 33%-60%, with average titers ranging from 5.6 × 1012 to 2.4 × 1013 PFU/mL (Plaque-Forming Unit). Furthermore, multilocus sequence typing (MLST) analysis of the bacterial isolates revealed 14 distinct STs, mostly belonging to ST131, ST410, and ST648. Notably, the phage susceptibility spectra of ST73, ST13003, ST648, ST2311, ST167, ST405, ST607, ST7962, and ST131 were significantly different. Thus, the isolated phages can effectively lyse CREC isolates, particularly those with clinically dominant STs. Conversely, ST410 exhibited a 14.2%-87.14% susceptibility spectrum, whereas ST1139, ST1487, ST10, and ST206 did not lyse, suggesting the presence of more resistant STs. Future studies are warranted to identify the reasons behind this resistance and address it. Ultimately, this study will aid in developing focused treatments to address these pressing global health issues.

Next-Generation strategies to combat antimicrobial resistance: Integrating genomics, CRISPR, and novel therapeutics for effective treatment

Antimicrobial resistance (AMR) poses a significant threat to global public health, necessitating innovative strategies to combat this escalating issue. This review outlines next-generation approaches integrating genomics, CRISPR technology, and novel therapeutics to effectively address AMR. Genomic techniques enable comprehensive understanding of the genetic mechanisms underpinning resistance, facilitating the development of targeted interventions. By sequencing the genomes of resistant pathogens, researchers can identify resistance genes, track their spread, and predict emerging resistance patterns. CRISPR-Cas systems offer a revolutionary tool for combating AMR through precise genome editing. This technology can disrupt resistance genes, restore antibiotic sensitivity, and develop bacteriophage therapies that selectively target resistant bacteria. Moreover, CRISPR-based diagnostics enable rapid, accurate detection of resistant strains, enhancing infection control measures. The advent of novel therapeutics, such as antimicrobial peptides, bacteriophage therapy, and synthetic biology-derived compounds, provides alternative treatment options. These therapeutics can bypass traditional resistance mechanisms and exhibit efficacy against multi-drug resistant organisms. Additionally, integrating artificial intelligence (AI) and machine learning with genomics and CRISPR can accelerate the discovery of new antibiotics and predict resistance trends, optimizing treatment regimens. Implementing these next-generation strategies requires robust global collaboration, regulatory frameworks, and investment in research and development. By combining genomics, CRISPR, and novel therapeutics, we can create a multifaceted approach to overcome AMR, ensuring effective treatments and safeguarding public health. This integration represents a paradigm shift in antimicrobial strategy, offering hope for a future where resistant infections can be effectively managed and treated.

Novel Thiazole-Hydrazide Derivatives and Their Anticancer Properties

Objective: Cancer is described as uncontrolled cell division, and it is a major problem in Türkiye, as well as around the world. Current treatment options are insufficient in some cases, particularly the treatment rate for lung cancer cases, which is very low. Meanwhile, current pharmaceuticals have several side effects, such as drug-drug interactions, and cognitive disorders. Additionally, developing drug resistance is a major problem for current and future management of the disease. Accordingly, the search for new molecules or alternative treatment options is actively achieved. Methods: In this study, eight novel thiazole-hydrazide analogs were designed and synthesized, and their structural elucidation was performed via HRMS, 1H-NMR, and 13C-NMR. Their biological activity profile was investigated on A549 lung carcinoma and MCF7 breast adenocarcinoma cells. To determine the selective cytotoxicity on cancer cells, they were also tested against NIH/3T3 healthy cell line. Besides that, an in silico study was performed to understand the binding modes of the compounds. Results: The results showed that in the serial 4f and 4g, the most bulky analogues, showed no inhibition against any cell type, even at the highest concentration tested. On the other hand, 4a, 4b, 4d, 4e, and 4h showed less cytotoxicity on healthy cells than A549 cells, so they exhibited significant cytotoxicity and a selective profile against A549 cancer cells. While they also inhibited MCF7 cells. The major point is that para-chlorophenyl analogs at the fourth position on thiazole (4a and 4d) displayed a better anticancer profile than ortho-chlorophenyl analogs. These two compounds were also investigated for their apoptotic effects using in silico studies. Both experimental and in silicon studies revealed that the combination of thiazole and hydrazinoacetyl has a significant impact against cancer cells, and in silico study also suggested that tri-substitute thiazole ring has anticancer potential that induced cancer cell death via apoptosis. Conclusion: Results of this study was presented that compound 4a was the most potent compound against lung cancer cells (A549) and 4d was the most potent compound against breast cancer cells (MCF-7). Furthermore, analyzing the molecular docking study for promising compounds (4a and 4d) suggested that interactions with the loop region residues have a pivotal role in inducing caspase-3 enzyme activity. It was concluded that hybridization of thiazole and hydrazinoacetyl moieties is responsible for the anticancer activity.

Novel therapeutic receptor agonists and antagonists in allergic conjunctivitis.

Allergic conjunctivitis is characterized by the development of pathophysiological changes to the ocular surface, which occurs when pro-allergic and pro-inflammatory mediators interact with their cognate receptors expressed on immune and nonimmune cells. Traditional treatments with antihistamines and corticosteroids provide relief, but there is a need for more efficacious and tolerable long-term therapy with a better safety profile. This article aims to provide an overview of the mode of action and clinical application of agonist therapies targeting glucocorticoid, melanocortin, and toll-like receptors, as well as antagonist therapies targeting cytokine, chemokine, integrin, and histamine receptors. There has been considerable advancement in immunology and pharmacology, as well as a greater understanding of the cellular and molecular mechanisms of allergic conjunctivitis. Recent research advancing therapy for allergic conjunctivitis has focused on developing synthetic molecules and biologics that can interfere with the process of the allergic immune reaction. This review discusses novel therapeutic receptors being explored agonistically or antagonistically to develop alternative treatment options for allergic conjunctivitis. These novel approaches hold promise for improving the management of allergic eye diseases, offering patients hope for more effective and safer treatment options in the future.

Clinical Outcome Using Different Catheter Interventional Treatment Modalities in High-Risk Pulmonary Artery Embolism.

For patients with high-risk pulmonary artery embolism (PE), catheter-directed therapies pose a viable alternative treatment option to systemic thrombolysis or anticoagulation. Right now, there are multiple devices available which have been proven to be safe and effective in lower-risk settings. There is, however, little data comparing their efficacies in high-risk PE. We performed a retrospective, single-center study on patients with high-risk PE undergoing catheter interventional treatment. Patients receiving large-bore catheter thrombectomy were compared to patients receiving alternative treatment forms. Of the 20 patients included, 9 received large-bore thrombectomy, and 11 received alternative interventional treatments. While the baseline characteristics were comparable between the two groups, periprocedural and in-hospital mortality tended to be significantly lower with large-bore thrombectomy when compared to other treatment forms (0 vs. 55% and 33 vs. 82%, p = 0.07 and 0.01, respectively). In this small, retrospective study, large-bore thrombectomy was associated with lower mortality as compared to alternative treatment forms. Future prospective research is needed to corroborate these findings.

Overexpression of BubR1 Mitotic Checkpoint Protein Predicts Short Survival and Influences the Progression of Cholangiocarcinoma.

Budding Uninhibited by Benzimidazole-Related 1 (BubR1) or BUB1 Mitotic Checkpoint Serine/Threonine Kinase B (BUB1B) is an essential component of the spindle assembly checkpoint (SAC), which controls chromosome separation during mitosis. Overexpression of BubR1 has been associated with the progression of various cancers. This study demonstrated that high expression of BubR1 correlated with cholangiocarcinogenesis in a hamster cholangiocarcinoma (CCA) model and was associated with shorter survival in patients with CCA. Co-expression of BubR1 and MPS1, which is a SAC-related protein, indicated a shorter survival rate in patients with CCA. Knockdown of BubR1 expression by specific siRNA (siBubR1) significantly decreased cell proliferation and colony formation while inducing apoptosis in CCA cell lines. In addition, suppression of BubR1 inhibited migration and invasion abilities via epithelial-mesenchymal transition (EMT). A combination of siBubR1 and chemotherapeutic drugs showed synergistic effects in CCA cell lines. Taken together, this finding suggested that BubR1 had oncogenic functions, which influenced CCA progression. Suppression of BubR1 might be an alternative option for CCA treatment.

OKN-007 is an Effective Anticancer Therapeutic Agent Targeting Inflammatory and Immune Metabolism Pathways in Endometrial Cancer.

Advanced-stage endometrial cancer patients typically receive a combination of platinum and paclitaxel chemotherapy. However, limited treatment options are available for those with recurrent disease, and there is a need to identify alternative treatment options for the advanced setting. Our goal was to evaluate the pre-clinical efficacy and mechanism of action of Oklahoma Nitrone 007 (OKN-007) alone and in combination with carboplatin and paclitaxel in endometrial cancer. The effect of OKN-007 on the metabolic viability of endometrial cancer cells in both two- and three-dimensional (2D and 3D) cultures, as well as on clonogenic growth, in vitro was assessed. We also evaluated OKN-007 in vivo using an intraperitoneal xenograft model and targeted gene expression profiling to determine the molecular mechanism and gene expression programs altered by OKN-007. Our results showed that endometrial cancer cells were generally sensitive to OKN-007 in both 2D and 3D cultures. OKN-007 displayed a reduction in 3D spheroid and clonogenic growth. Subsequent targeted gene expression profiling revealed that OKN-007 significantly downregulated the immunosuppressive and immunometabolic enzyme indolamine 2,3-dioxygenase 1 (IDO1) (-11.27-fold change) and modulated upstream inflammatory pathways that regulate IDO1 expression (interferon- (IFN-), Jak-STAT, TGF-β, and NF-kB), downstream IDO1 effector pathways (mTOR and aryl hydrocarbon receptor (AhR)) and altered T-cell co-signaling pathways. OKN-007 treatment reduced IDO1, SULF2, and TGF-β protein expression in vivo, and inhibited TGF-β, NF-kB, and AhR- receptor-mediated nuclear signaling in vitro. These findings indicate that OKN-007 surmounts pro-inflammatory, immunosuppressive, and pro-tumorigenic pathways and is a promising approach for the effective treat endometrial cancer. Significance Statement Women with advanced and recurrent endometrial cancer have limited therapeutic options. OKN-007, which has minimal toxicity and is currently being evaluated in early-phase clinical trials for the treatment of cancer, is a potential new strategy for the treatment of endometrial cancer.

Treatment of infections caused by carbapenem-resistant Acinetobacter baumannii.

Patients with severe carbapenem-resistant Acinetobacter baumannii (CRAB) infections currently face significant treatment challenges. When patients display signs of infection and the clinical suspicion of CRAB infections is high, appropriate treatment should be immediately provided. However, current treatment plans and clinical data for CRAB are limited. Inherent and acquired resistance mechanisms, as well as host factors, significantly restrict options for empirical medication. Moreover, inappropriate drug coverage can have detrimental effects on patients. Most existing studies have limitations, such as a restricted sample size, and are predominantly observational or non-randomized, which report significant variability in patient infection severity and comorbidities. Therefore, a gold-standard therapy remains lacking. Current and future treatment options of infections due to CRAB were described in this review. The dose and considerable side effects restrict treatment options for polymyxins, and high doses of ampicillin-sulbactam or tigecycline appear to be the best option at the time of initial treatment. Moreover, new drugs such as durlobactam and cefiderocol have substantial therapeutic capabilities and may be effective salvage treatments. Bacteriophages and antimicrobial peptides may serve as alternative treatment options in the near future. The advantages of a combination antimicrobial regimen appear to predominate those of a single regimen. Despite its significant nephrotoxicity, colistin is considered a primary treatment and is often used in combination with antimicrobials, such as tigecycline, ampicillin-sulbactam, meropenem, or fosfomycin. The Infectious Diseases Society of America (IDSA) has deemed high-dose ampicillin-sulbactam, which is typically combined with high-dose tigecycline, polymyxin, and other antibacterial agents, the best option for treating serious CRAB infections. A rational combination of drug use and the exploration of new therapeutic drugs can alleviate or prevent the effects of CRAB infections, shorten hospital stays, and reduce patient mortality.

Carbapenem-resistant Acinetobacter baumannii infections among diabetic and non-diabetic patients and possible effective combination treatments

BackgroundCarbapenems are one of the most noteworthy choices for treating multidrug-resistant Acinetobacter baumannii (A. baumannii). Currently, carbapenem-resistant A. baumannii (CRAB) represents a healthcare problem worldwide, particularly among diabetic patients who are more susceptible to microbial infections. The aim of this study was to investigate the differences in antibiotic susceptibility profiles, the abundance of carbapenem resistance genes across A. baumannii-infected diabetic and non-diabetic patients, and the antimicrobial activity of different antibiotic combinations on highly resistant isolates.MethodsData of 99 A. baumannii-infected patients were collected during the period from 2018 to 2022 and categorized according to patients’ diabetes status into either diabetic or non-diabetic group. A total of 45 A. baumannii isolates were collected during 2021 and 2022 from the main hospital laboratory to be reidentified and genetically confirmed. Antibiotic susceptibility, including carbapenems, was determined using disc agar diffusion and broth microdilution methods. The isolates were screened for OXA-23, GES, VIM, and NDM carbapenem-resistant genes. Five antibiotic combinations were assessed using the double-disk synergy and checkerboard methods.ResultsThe findings of the current study revealed that multidrug resistance increased gradually, from 56% in 2018 to 95.6% in 2022. Moreover, CRAB increased among diabetics and non-diabetics. Resistance rates of imipenem, meropenem, and doripenem reached 68.8%, 61.8%, and 47.4% in diabetics and 97.9%, 83.3%, and 50% in non-diabetics, respectively. The VIM gene was the most prevalent gene with prevalence rates of 100% and 96.15% in diabetics and non-diabetics, respectively. Moreover, all A. baumannii isolates carried at least two of the selected carbapenem-resistant genes. Across the different used combinations, only the tigecycline-meropenem combination showed synergistic activity in 50% of diabetic and 66.7% of non-diabetic isolates.ConclusionsAn increased carbapenem resistance was observed among A. baumannii-infected individuals, both diabetic and non-diabetic. The MEM/TCG combination was the only one that showed synergistic or additive effects against highly resistant isolates making it a viable alternative treatment option.

The efficacy of cone-beam computed tomography-guided transcatheter arterial chemoembolization in hepatocellular carcinoma survival: A systematic review.

Cone-beam computed tomography (CBCT)-guided transcatheter arterial chemoembolization (TACE) represents an alternative treatment option for advanced hepatocellular carcinoma (HCC) patients, yet a comprehensive evaluation of CBCT guidance on this procedure and CBCT's impact on patient survival remains lacking. We aimed to assess the efficacy and benefits of CBCT-guided TACE in improving survival outcomes for patients with HCC and show the importance of CBCT in interventional radiology. Meta-analysis was conducted to evaluate CBCT-guided TACE compared to conventional TACE in the treatment of HCC. PubMed and Cochrane library databases were searched for studies published. Outcomes of interest included 1- or 3-year local progression-free survival (LPFS) rates, overall survival (OS) rates, and tumor response results. A total of eight studies were included in the meta-analysis, comprising 1176 patients. The analysis showed that CBCT-guided TACE improved 1-year LPFS (odds ratio [OR] = 2.81, P < 0.001), 3-year (OR = 4.42, P = 0.002), and the 3-year OS rates (OR = 3.03, Confidence Interval = 1.65-11.80, P = 0.14) compared to conventional TACE. CBCT-guided TACE enhances survival outcomes for patients with HCC; by addressing this research gap, our study endeavors to encourage clinicians and researchers to pursue this medical technology by providing a robust synthesis of current evidence.

Implementation of a Patient Decision Aid for Atrial Fibrillation Ablation Improves Patient Procedural Knowledge but Does Not Impact Perceived Involvement With the Shared Decision-Making Process.

Shared decision-making (SDM) is a method for a patient and physician to cooperatively consider a diagnostic or therapeutic option, ultimately empowering the patient to make an informed decision. Atrial fibrillation (AF) ablation is a procedure that would benefit from SDM given the risk of serious adverse events, the high rate of arrhythmia recurrence, and alternative treatment options. Implementing a patient decision aid (PDA) may help facilitate AF ablation SDM by succinctly conveying important information to patients. Patients scheduled for initial AF catheter ablation were randomized to a virtual SDM visit utilizing a PDA, which covered procedural risks and benefits, or a virtual control visit with a tool outlining periprocedural processes. Preoperatively, patients completed a questionnaire assessing procedural risk and benefit knowledge, as well as perceived involvement with the decision-making process. Unpaired t-tests were used to compare groups. The SDM group scored significantly better overall on knowledge-based questions compared to the control group (69% correct [n=34] vs 53% [n=32]; P=0.00013). In particular, the SDM group was significantly more likely to answer questions correctly about stroke risk (P=0.01), anticoagulation (P=0.01), and potential need for additional procedures (P=0.03 and P=0.03). Perceived involvement in the decision-making process was overall not improved with PDA use (4.7 vs 4.6 out of 5; P=0.72). The addition of a PDA for AF ablation significantly improved procedural knowledge but did not impact patients' perceived involvement in the decision-making process compared to traditional preprocedural discussion alone.

EC-IC bypass for occlusion of the internal carotid artery

There are barely any alternative treatment options to the drug treatment of hemodynamically caused cerebral ischemia, as in occlusion of the internal carotid artery. For secondary prevention of an ischemic stroke due to carotid occlusion and hemodynamic instability, extracranial-intracranial (EC-IC) bypass surgery can be an important option in selected patients. The development, study situation, indications and surgical technique for placement of an EC-IC bypass in cases of occlusion of the internal carotid artery are presented. With appropriate expertise and strict selection of patients, the placement of an EC-IC bypass enables stabilization of cerebral perfusion with a low rate of complications. The study situation is controversially discussed; nevertheless, surgical treatment in a specialized neurovascular center should at least be considered.

On-treatment decline in MELD score predicts one-month transplant-free survival in rodenticidal hepatotoxicity patients treated with low-volume plasma exchange.

Plasma exchange (PLEX) improves survival in patients with rodenticidal hepatotoxicity. However, predictors of treatment response are unknown. We aimed at assessing predictors of response to PLEX treatment in these patients. Patients with rodenticidal hepatotoxicity from 2014 to 2023 managed in our department were included in this study. Kochi criteria (model for end-stage liver disease [MELD] score 36 or international normalized ratio [INR] 6 with hepatic encephalopathy[HE]) derived specifically for rodenticidal hepatotoxicity (PubMed IDentifier [PMID]: 26310868) were used to assess need for liver transplantation. We analyzed predictors of survival at onemonth. ∆Bilirubin, ∆MELD score and ∆INR were calculated as percentage change of the parameter after third PLEX session (or after last PLEX if < 3 PLEX sessions done) from baseline pre-PLEX value. Of 200 patients with rodenticidal hepatotoxicity, 114 patients were treated with low-volume PLEX (PLEX-LV). No patient had liver transplantation. Of 78 patients who fulfilled Kochi criteria, 32 patients were PLEX-LV eligible and underwent PLEX-LV (M: 10; age: 20.5, 7-70years; median, range; acute liver failure: 24). Twenty-two (69%; acute liver failure: 14) of the 32 patients were alive at onemonth. Presence of HE (p = 0.03) and ∆MELD (p < 0.001) were significant predictors on univariate analysis, while ∆MELD (aOR = 0.88, 95% CI: 0.79-0.98, p = 0.01) was the only significant independentpredictor of one-month transplant-free survival. Area under receiver operating characteristic (ROC) for ∆MELD was 0.93 (95% CI:0.85-1.00) and a decrease of 20% in MELD score while on PLEX-LV had 90% sensitivity and 90% specificity in predicting one-month survival. Decline in MELD while on PLEX-LV independently predicted one-month transplant-free survival in rodenticidal hepatotoxicity patients. This may help guide decision on stopping PLEX-LV in patients predicted to respond to treatment and to consider alternate treatment options in non-responders.

Coil embolization of the middle cerebral artery bifurcation aneurysms: Feasibility and durability

ObjectiveTo evaluate the feasibility and durability of coil embolization for MCAB aneurysms by analyzing clinical and radiological results. MethodsFrom January of 2008 to June of 2018, we treated a total of 1785 aneurysms using coil embolization. The aneurysms were treated by both coiling and stent-assisted coiling. Among these cases, 223 MCAB aneurysms were analyzed retrospectively. Clinical and radiological assessments were conducted at admission, after treatment, at discharge, and at last clinical follow-up. ResultsCoil embolization was performed on 223 MCAB aneurysms in 217 patients. Peri-procedural ischemic, hemorrhagic, and other complications within 30 days after coil embolization occurred at rates of 8.0 %, 8.0 %, and 2.0 %, respectively, in the ruptured group and at 2.9 %, 1.2 %, and 0 %, respectively, in the unruptured group. The overall morbidity and mortality rates associated with complications were 2.3 % and 2.0 %. The cumulative major recurrence rates were 5.1 % at 12 months, 7.1 % at 18 months, and 11.9 % at three years after coil embolization. The mean follow-up period was 33.27 ± 25.48 months. Independent risk factors for major recurrence after coil embolization for MCAB aneurysms were a ruptured aneurysm, initial incomplete occlusion, the aneurysm size, and the neck size. ConclusionCoil embolization is a good alternative treatment option for MCAB aneurysms compared to surgical clipping. Considering the risk factors for major recurrence, the follow-up angiography should continue up to three years after coil embolization.

Is a Low Dosage of Medical Cannabis Effective for Treating Pain Related to Fibromyalgia? A Pilot Study and Systematic Review.

Background and Objectives: Fibromyalgia is a multifaceted and frequently misunderstood chronic pain disease marked by widespread musculoskeletal pain and cognitive/somatic dysfunction. This trial aims to contribute to the existing knowledge on treating fibromyalgia (FM) with medical cannabis (Cannabis sativa L.) and explore a safer and more effective cannabis administration method. The goal is to provide evidence-based findings that can guide alternative treatment options for FM patients by assessing a pilot study. Materials and Methods: The trial was performed at the pain therapy unit of the San Carlo Hospital (Potenza, Italy) by administrating to 30 FM patients 100 mg/day of Bedrocan® (Bedrocan International, Veendam, The Netherlands) as a decoction. The Numerical Rating Scale (NRS) and SF-12 short-form health questionnaire were used to evaluate pain intensity and the quality of life at the beginning of the study and the 6th-month follow-up. A systematic review of all clinical studies investigating the use of cannabis to reduce FM was also undertaken to place this study in the context of the existing evidence base. Results: Pain intensity evaluated with the NRS lowered from a median of 8 [95% CI 7.66-8.54] at a baseline to a median of 4 (95% CI 3.28-4.79) after 6 months of follow-up (p-value < 0.001; t-test). Similarly, significant physical and mental state improvement, evaluated with the SF-12 questionnaire, was found in 96.67% and 82.33% of patients, respectively (95% CI 44.11-51.13 for the physical state, and 53.48-58.69 for mental state assessed after the 6th-month follow-up; p-value < 0.001; t-test). The systematic analysis of the literature identified 10 clinical trials concerning the treatment of fibromyalgia with cannabis. Conclusions: Considering results from the present pilot study and systematic review, it is possible to assume that medical cannabis may be considered an alternative therapy for FM patients who do not respond to conventional pharmacological therapy.
