Analytic First-Order Derivatives of CASPT2 Combined with the Polarizable Continuum Model.
J Chem Theory Comput
January 2025
The complete active space second-order perturbation theory (CASPT2) is valuable for accurately predicting electronic structures and transition energies. However, optimizing molecular geometries in the solution phase has proven challenging. In this study, we develop analytic first-order derivatives of CASPT2 using an implicit solvation model, specifically the polarizable continuum model, within the open-source package OpenMolcas.

- Previous trials suggest no overall benefit of screening for occult cancer in patients with venous thromboembolism (VTE), but high-risk patients may still benefit.
- A study involving 3,706 patients with acute VTE found that the incidence of newly diagnosed cancer increased over time, reaching 3.7% at one year and 7.0% at three years.
- Factors such as older age, a history of cancer, autoimmune disorders, past major bleeding, and lack of transient VTE risk factors were identified as independent predictors for new cancer diagnoses post-VTE.
There is a scarcity of data on clinical outcomes after intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) in patients with multivessel disease and chronic kidney disease (CKD). The Optimal Intravascular Ultrasound (OPTIVUS)-Complex PCI study multivessel cohort was a prospective multicenter single-arm trial enrolling 1,015 patients who underwent multivessel IVUS-guided PCI including left anterior descending coronary artery target with an intention to meet the prespecified OPTIVUS criteria for optimal stent expansion. We compared the clinical outcomes between patients with and without CKD.

- * Out of 1507 cancer patients studied, 4.7% experienced an ischemic stroke over a median follow-up of 1020 days, with a cumulative incidence of 4.0% at 1 year.
- * Key risk factors for stroke include specific cancers (pancreatic, ovarian, lung), dyslipidemia, metastasis, elevated D-dimer levels, and younger age, highlighting the need for vigilant monitoring in these patients.
Article Synopsis
- * The research included 115 T1DM patients and assessed their dietary habits, abdominal symptoms, and serum anti-tissue transglutaminase (TTG) antibody levels to diagnose CD.
- * Results showed that 50.4% of patients reported abdominal symptoms, but none had elevated TTG levels, leading to the conclusion that the prevalence of CD in Japanese patients with T1DM is 0%, indicating a lower occurrence than seen in other countries.
Background: The optimal duration of anticoagulation therapy for patients with cancer and acute low-risk pulmonary embolism (PE) is clinically relevant, but evidence is lacking. Prolonged anticoagulation therapy could have a potential benefit for prevention of thrombotic events; however, it could also increase the risk of bleeding.
Methods: In a multicenter, open-label, adjudicator-blinded, randomized clinical trial at 32 institutions in Japan, we randomly assigned patients with cancer and acute low-risk PE of the simplified version of the Pulmonary Embolism Severity Index score of 1, in a 1:1 ratio, to receive either an 18-month or a 6-month rivaroxaban treatment.
Background: Multimorbidity increases with age, leading to various adverse outcomes, including higher mortality, care dependency, hospitalizations, and healthcare costs. Polydoctoring, managing a patient with multimorbidity by multiple healthcare providers, can be a risk of fragmented care and increased healthcare expenditures. This study aims to identify patient-related factors contributing to polydoctoring in older adults with multimorbidity.

Totally endoscopic robotic repair of coronary sinus atrial septal defect with concomitant tricuspid annuloplasty.
Gen Thorac Cardiovasc Surg Cases
September 2024
Background: The coronary sinus type of atrial septal defect is rare. Standard treatment typically involves intracardiac repair using conventional sternotomy or thoracotomy incisions; however, robotic technology can offer a feasible alternative due to its ability to provide a high-quality surgical view of this anomaly.
Case Presentation: A 72-year-old man presented with asymptomatic atrial septal defect.
Article Synopsis
- Extracorporeal membrane oxygenation (ECMO) may be necessary for some patients with severe pulmonary embolism (PE), but its clinical outcomes are not well understood.
- *In a study analyzing data from 2035 patients with acute PE, 76 required ECMO, with findings indicating high rates of cardiac arrest (88.2%) at diagnosis and a 30-day death rate of 30.3%, all related to PE.
- *The research highlighted significant complication rates, including a 54% incidence of major bleeding, suggesting the need for improved management strategies and future clinical trials.
Background: Left atrial (LA) plication is a procedure used to correct an LA that expands posteriorly due to remodeling. This study aimed to determine the efficacy of additional LA plication in reducing postoperative cardiovascular events (CVEs) after mitral valve (MV) repair in atrial functional mitral regurgitation (MR) patients.
Methods: Between October 2008 and August 2023, MV repair with or without LA plication in 74 patients was studied.
Article Synopsis
- Elevated white blood cell (WBC) counts are identified as a risk factor for adverse outcomes in patients with venous thromboembolism (VTE) who do not have active cancer.
- In a study involving 5,197 patients, those with the highest WBC counts (Q4) were more likely to experience severe forms of VTE like pulmonary embolism and had a significantly higher risk of death and major bleeding over five years.
- The findings suggest that monitoring WBC counts at VTE diagnosis can help in assessing patient risk and potential outcomes.
Malassezia species are lipophilic yeasts recognized for causing skin manifestations, such as pityriasis versicolor. In addition, Malassezia can lead to invasive infection, mostly intravascular catheter-associated sepsis-related lipid-containing total parenteral nutrition in neonates and immunocompromised hosts. We experienced a case of invasive pulmonary Malassezia infection in a patient with refractory ulcerative colitis undergoing immunosuppressive treatment without lipid-containing total parenteral nutrition.

- Remote ischemic periconditioning (RIPC) enhances cardioprotection and outcomes during urgent procedures in STEMI patients but its effects on cardiac sympathetic nerve activity were unclear.
- The study involved assigning STEMI patients to either RIPC or a control group during emergency PCI, measuring cardiac nerve activity via I-MIBG imaging.
- While initial discharge measurements showed no significant differences in cardiac sympathetic activity between groups, at a 1-year follow-up, the RIPC group exhibited lower sympathetic nerve activity and better imaging results in nonculprit lesions, indicating a lasting positive effect of RIPC.
Article Synopsis
- * The COMMAND VTE Registry-2 study tracked 5,197 patients with venous thromboembolism in Japan, finding that 2.3% of those with acute PE developed CTEPH over an average follow-up of 747 days.
- * Identified risk factors for developing CTEPH included being female, longer time from symptom onset to PE diagnosis, experiencing hypoxemia, having right heart load, lower D-dimer levels, and having
Article Synopsis
- The simplified Pulmonary Embolism Severity Index (sPESI) score helps identify low-risk patients for home treatment of pulmonary embolism, but its use with direct oral anticoagulants hasn't been thoroughly studied.
- A study of 2,496 patients with stable pulmonary embolism found that only 25% had an sPESI score of 0, and among those, only 17% were treated at home, though their 30-day mortality was notably low (0% vs. 4.8% in higher risk groups).
- Factors promoting home treatment included the absence of temporary risk factors, no elevated cardiac biomarkers, and the use of direct oral anticoagulants during the acute phase.
Background: The micro-axial flow pump Impella, a new mechanical circulatory device for cardiogenic shock, is still only available in a limited number of hospitals, due to the facility certification requirements and insufficient evidence of the benefit of introducing Impella in hospitals. This study aimed to evaluate the impact of introducing Impella in hospitals on in-hospital mortality of patients treated with extracorporeal membrane oxygenation (ECMO).
Methods: Using a nationwide Japanese inpatient database, we identified patients who received ECMO during hospitalization between 1 April 2014 and 31 March 2021.
Objectives: This study aimed to evaluate the efficacy of preoperative computed tomography in assessing mitral annulus anatomy and the posterior annular plication rate in mitral valve repair with annuloplasty.
Methods: From July 2018 to August 2023, we performed robotic mitral valve repair with ring annuloplasty using a semi-rigid ring in 100 patients. Preoperative anatomical assessment of the mitral annulus was conducted by three-dimensional computed tomography.
Article Synopsis
- Advanced genetic studies have identified mutations in the FUS/TLS gene, important for DNA repair and RNA processing, as a cause of familial ALS.
- A CRISPR-Cas9 technique was used to create mouse models with the FUS-ALS mutation, which exhibited progressive motor impairment and neuron damage, similar to symptoms seen in ALS patients.
- The findings support the idea that disruptions in nuclear structure are significant in ALS, highlighting the potential of these models for future research and therapy development.
Article Synopsis
- * In a subgroup analysis of 601 patients, those with anemia showed significantly fewer recurrent venous thromboembolism (VTE) cases with 12-month edoxaban treatment compared to 3 months, while no such reduction was observed in patients without anemia.
- * Overall, 12-month edoxaban treatment was more effective in preventing thrombotic events for both anemia and no-anemia groups, with no significant difference in major bleeding risk between the two treatment durations.
Article Synopsis
- The ONCO DVT study found that a 12-month course of edoxaban is more effective than a 3-month course for preventing thrombotic events in cancer patients with isolated distal deep vein thrombosis (DVT).
- This analysis categorized 601 patients into three groups based on their modified Ottawa score (low, intermediate, high) to determine the effectiveness of extended anticoagulation.
- Results showed that extended treatment significantly reduced thrombotic events in the intermediate and high score groups but not in the low score group, indicating limited benefit for those with a low risk.
Desmoplakin (Dsp) is a component of desmosomal cell-cell junctions that interacts with the cadherin complex and cytoskeletal intermediate filaments. In addition to its function as an adhesion component, Dsp is involved in various biological processes, such as gene expression, differentiation, and migration. Dsp is specifically expressed in the hippocampal dentate gyrus (DG) in the central nervous system.
