Methods: Seventy patients with pacemaker indications for atrioventricular block were randomly assigned to the delivery catheter and stylet groups.

Patterns and Incidence of Pneumonitis and Initial Treatment Outcomes with Durvalumab Consolidation Therapy after Radical Chemoradiotherapy for Stage III Non-Small Cell Lung Cancer.

Durvalumab consolidation after chemoradiotherapy for stage III non-small cell lung cancer (NSCLC) has become the standard of care. Single-center results were examined for treatment outcomes and patterns of pneumonitis in clinical practice. Patients with stage III NSCLC who underwent chemoradiotherapy at our institution (n = 150) were included.

Mathematical model for promotion of wound closure with ATP release.

To computationally investigate the recent experimental finding such that extracellular ATP release caused by exogeneous mechanical forces promote wound closure, we introduce a mathematical model, the Cellular Potts Model (CPM), which is a popular discretized model on a lattice, where the movement of a "cell" is determined by a Monte Carlo procedure. In the experiment, it was observed that there is mechanosensitive ATP release from the leading cells facing the wound gap and the subsequent extracellular Ca influx. To model these phenomena, the Reaction-Diffusion equations for extracellular ATP and intracellular Ca concentrations are adopted and combined with CPM, where we also add a polarity term because the cell migration is enhanced in the case of ATP release.

[Regimen Selection by Narrative Approach in Patients with Advanced Gastric Cancer-Paclitaxel or Nab-Paclitaxel?].

Background: According to the sixth Gastric Cancer Treatment Guideline, the regimen included nab-paclitaxel(nab-PTX) is a conditional recommendation as second-line treatment for advanced gastric cancer. However, the selection criteria of nab-PTX is not clear.

Method: Questionnaire survey as narrative approach on the problems of paclitaxel premedication, the symptoms due to paclitaxel containing alcohol, and infusion time was conducted for patients who had been treated with paclitaxel.

[Questionnaire Survey on Oral Care and Oral Troubles for Patients with Gastric Cancer Received Chemotherapy].

Background: The actual situation of oral care and oral troubles for patients with gastric cancer received chemotherapy is not clear.

Methods: Questionnaire survey in the form of oral questions was performed for patients with gastric cancer who received chemotherapy from December 2021 to February 2022. The relevance between the survey results and background factors was examined using the χ2 test.

Delivery catheter system carries more physiological right ventricular septal pacing than stylet system.

Introduction: The Mt. FUJI multicenter trial demonstrated that a delivery catheter system had a higher rate of successful right ventricular (RV) lead deployment on the RV septum (RVS) than a conventional stylet system. In this subanalysis of the Mt.

Denosumab-induced hypocalcemia in patients with solid tumors and renal dysfunction: a multicenter, retrospective, observational study.

Background: Bone metastases are frequently observed in advanced cancer, and bone modifying agents are used to prevent or treat skeletal-related events. Zoledronic acid is contraindicated in patients with severe renal impairment (Ccr < 30 mL/min), but it is not completely known whether denosumab can be used in them. We aimed to determine the association between renal function and hypocalcemia development during denosumab treatment.

[A Case of Preoperative Chemotherapy for Advanced Gastric Cancer, Laparoscopic Total Gastrectomy, Pancreaticoduodenectomy, and Para-Aortic Lymph Node Dissection].

Bulky N+ gastric cancer has a poor prognosis. The results of JCOG0405 showed the efficacy of neoadjuvant chemotherapy with S-1 plus cisplatin combination therapy for Bulky N+ gastric cancer. JLSSG0901 demonstrated the safety and efficacy of laparoscopic surgery for advanced gastric cancer.

[Conversion Surgery Performed after SOX plus Nivolumab Therapy for Advanced Gastric Cancer with Para-Aortic Lymph Node Metastasis].

The patient was a 78-year-old woman. She presented with anemia and a positive fecal occult blood test. Endoscopic findings revealed type 3 advanced gastric cancer.

[A Case of Fibromatosis-Like Tumor Which Was Difficult to Differentiate from Local Recurrence of Ascending Colon Cancer].

A 60s female, who had undergone single-incision laparoscopic ileocecal resection for ascending colon cancer with pathological diagnosis of T3N1bM0, Stage Ⅲb, followed by adjuvant therapy with 8 courses CAPOX 2 years ago, had enhanced- computed tomography(CT)for follow-up and a 15-mm nodule near anastomotic site was found. 18F-fluorodeoxyglucose (FDG)-positron emission tomography(PET)CT revealed abnormal accumulation of 18F-FDG only to the lesion and diagnosis of"anastomotic recurrence"was made. We planned and safely performed resection of the anastomotic site and the nodule.

[A Case of Diffuse Large B-Cell Lymphoma Which Was Diagnosed during the Best Supportive Care of Recurrent Ascending Colon Cancer].

A 70s male, who had undergone single-incision laparoscopic ileocecal resection for ascending colon cancer with pathological diagnosis of T3N3M0, Stage Ⅲc(without adjuvant chemotherapy), had enhanced-computed tomography(CT)for 3-month follow-up and a hepatic low-density area, an newly emergent nodule behind inferior vena cava and distal ileal tumor were found. Three months later, enhanced CT showed that the distal ileal tumor got exponentially larger and the diagnosis of"malignant lymphoma"was suspected. The patient became sepsis, so we planned and safely performed partial resection of the tumor.

[A Case of 30s Female with Advanced Anal Canal Adenocarcinoma Managed with Adolescent-And-Young-Adult Team].

A 30s female complaining of anal pain and melena was referred to our hospital. The support by adolescent-and-young- adult(AYA)team was initiated after the first encounter.

Association of Malnutrition and High Bleeding Risk with Long-Term Prognosis in Patients with Acute Coronary Syndrome following Percutaneous Coronary Intervention.

Background: Malnutrition in cardiovascular disease is associated with poor prognosis, especially in patients with heart failure and acute coronary syndrome (ACS). High bleeding risk is also linked to coronary artery disease prognosis, including ACS. However, whether the extent of malnutrition and high bleeding risk have a cumulative impact on the long-term prognosis of patients with ACS who undergo percutaneous coronary intervention remains unclear.

Association between methicillin-resistant Staphylococcus aureus nasal carriage and infection after pancreatic surgery.

Background: Methicillin-resistant Staphylococcus aureus (MRSA) infections after pancreatectomy are relatively rare; however, they can be fatal when associated with pseudoaneurysms. For the past 12 years, we have been investigating nasal MRSA carriage by polymerase chain reaction testing, postoperatively in patients admitted to the intensive care units, to prevent nosocomial infections. Here, we investigated the relationship between MRSA nasal carriage and postoperative MRSA infection at the surgical site, following pancreatectomy.
