Role of Fyn expression in predicting the sensitivity to platinum‑based chemotherapy in patients with ovarian serous carcinoma.

Ovarian serous carcinoma is a gynecological malignancy associated with a high mortality rate, which is commonly diagnosed in the first instance at a late stage and has a propensity to develop resistance to platinum-based chemotherapy. Identifying reliable biomarkers for platinum sensitivity is critical for improving patient outcomes. The present retrospective study included 64 patients with high-grade serous ovarian carcinoma (Federation of Gynecology and Obstetrics stages III or IV).

Prognostic significance of pre-treatment albumin-bilirubin grade in metastatic urothelial carcinoma receiving pembrolizumab.

Background: Pre-treatment albumin-bilirubin grade is a useful biomarker for predicting prognosis in patients receiving immune checkpoint inhibitors for advanced malignancies. We evaluated the prognostic impact of pre-treatment albumin-bilirubin grade in patients receiving pembrolizumab for metastatic urothelial carcinoma.

Methods: In this multicenter retrospective study, we calculated pre-treatment albumin-bilirubin scores of 96 patients who received pembrolizumab for metastatic urothelial carcinoma between January 2018 and March 2022.

Evaluation of anti-severe acute respiratory syndrome coronavirus 2 antibody levels in coronavirus disease breakthrough infection during immunosuppressive therapy in a patient with connective tissue disease-related interstitial lung disease.

Herein, we report the case of a 67-year-old man with severe coronavirus disease (COVID-19) pneumonia and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) mRNA vaccine breakthrough infection during immunosuppressive therapy for connective tissue disease-related interstitial lung disease (CTD-ILD). The patient received glucocorticoids combined with tacrolimus as maintenance therapy. His serum anti-SARS-CoV-2-immunoglobulin G (IgG) antibody levels were extremely low at the onset of COVID-19 pneumonia, even after the second dose of SARS-CoV-2 mRNA vaccine (BNT162b2).

Transition from epoprostenol to selexipag in a patient with systemic sclerosis and pulmonary hypertension during the postoperative period of colon cancer surgery: A case report.

Introduction: Most pulmonary vasodilators are administered orally; however, in patients with pulmonary hypertension undergoing gastrointestinal surgery, a switch to parenteral drugs is needed. Parenteral pulmonary vasodilators carry a risk of infection and reduced quality of life owing to long-term central venous catheterization; therefore, it is preferable to switch them to oral vasodilators after surgery. Here, we present the case of a patient with systemic sclerosis complicated by pulmonary hypertension and colon cancer, for which treatment was successfully switched from epoprostenol to selexipag postoperatively.

Gut dysbiosis is associated with acceleration of lupus nephritis.

The gut microbiota (GM) exerts a strong influence over the host immune system and dysbiosis of this microbial community can affect the clinical phenotype in chronic inflammatory conditions. To explore the role of the GM in lupus nephritis, we colonized NZM2410 mice with Segmented Filamentous Bacteria (SFB). Gut colonization with SFB was associated with worsening glomerulonephritis, glomerular and tubular immune complex deposition and interstitial inflammation compared to NZM2410 mice free of SFB.

Revisiting Alkane Hydroxylation with m-CPBA (m-Chloroperbenzoic Acid) Catalyzed by Nickel(II) Complexes.

Mechanistic studies are performed on the alkane hydroxylation with m-CPBA (m-chloroperbenzoic acid) catalyzed by nickel(II) complexes, Ni (L). In the oxidation of cycloalkanes, Ni (TPA) acts as an efficient catalyst with a high yield and a high alcohol selectivity. In the oxidation of adamantane, the tertiary carbon is predominantly oxidized.

Successful rechallenge with cetuximab after progression with nivolumab for recurrent cervical lymph node metastasis from carcinoma of the tongue.

We can infer that the immunostimulatory effect of nivolumab and reactivation of cetuximab enhance the antitumor effect of the therapy.

To elucidate the fluid regulation in different menstrual cycle phases during xercise. Sex hormones affect fluid regulation in different ways. Moreover, the renin angiotensin-aldosterone system is activated in the luteal phase in rest.

Age-related differences in prognosis and prognostic factors among patients with epithelial ovarian cancer.

Approximately 40% of all patients with ovarian cancer in Japan are aged ≥65 years. The aim of the present study was to evaluate the differences in prognosis and prognostic factors between elderly and younger patients with epithelial ovarian cancer. A total of 114 patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-IV ovarian cancer who were initiated on primary treatment at the Osaka City University Hospital (Osaka, Japan) were included in this study.

Expression of UCP2 is associated with sensitivity to platinum-based chemotherapy for ovarian serous carcinoma.

The standard treatment for ovarian serous carcinoma is maximum debulking surgery and platinum-based chemotherapy. Despite the high response rate for chemotherapy, the majority of patients will be resistant to first-line agents and the prognosis for these patients is particularly poor. Currently there are no reliable methods to determine or predict platinum resistance.

The proinflammatory protein HMGB1 is a substrate of transglutaminase-2 and forms high-molecular weight complexes with autoantigens.

High-mobility group box 1 (HMGB1) is a chromatin-associated protein that, in response to stress or injury, translocates from the nucleus to the extracellular milieu, where it functions as an alarmin. HMGB1's function is in part determined by the complexes (HMGB1c) it forms with other molecules. However, structural modifications in the HMGB1 polypeptide that may regulate HMGB1c formation have not been previously described.

XPA expression is a predictive marker of the effectiveness of neoadjuvant chemotherapy for locally advanced uterine cervical cancer.

The standard treatment for locally advanced uterine cervical cancer is concurrent chemoradiotherapy. Successful neoadjuvant chemotherapy (NAC) may reduce tumor size and facilitate a hysterectomy, thereby improving the prognosis for patients with locally advanced cervical cancer. In contrast, unsuccessful NAC may worsen the prognosis because if a hysterectomy is not possible, the change in treatment plan may delay the initiation of core treatment.

TBX2 expression is associated with platinum-sensitivity of ovarian serous carcinoma.

The standard treatment for ovarian serous carcinoma comprises maximum debulking surgery and platinum-based chemotherapy. Despite the high response rate to chemotherapy, the majority of patients will be resistant to first-line agents and the prognosis for these patients is particularly poor. At present there are no reliable methods to determine or predict platinum resistance.

UCP2 expression may represent a predictive marker of neoadjuvant chemotherapy effectiveness for locally advanced uterine cervical cancer.

Concurrent chemoradiotherapy is the standard treatment for locally advanced uterine cervical cancer. However, effective neoadjuvant chemotherapy (NAC) can reduce tumor size and facilitate hysterectomy for locally advanced uterine cervical cancer. NAC treatment could improve the prognosis of patients with locally advanced cervical cancer.

Therapeutic Development of Mesenchymal Stem Cells or Their Extracellular Vesicles to Inhibit Autoimmune-Mediated Inflammatory Processes in Systemic Lupus Erythematosus.

Since being discovered over half a century ago, mesenchymal stem cells (MSCs) have been investigated extensively to characterize their cellular and physiological influences. MSCs have been shown to possess immunosuppressive capacity through inhibiting lymphocyte activation/proliferation and proinflammatory cytokine secretion while simultaneously demonstrating limited allogenic reactivity, which subsequently led to the evaluation of therapeutic feasibility to treat inflammatory diseases. Although regulatory constraints have restricted MSC development pharmacologically, limited clinical studies have shown encouraging results using MSC infusions to treat systemic lupus erythematosus (SLE); but, more trials will have to be performed to conclusively determine the clinical efficacy of MSCs to treat SLE.

Expression of epidermal growth factor-like domain 7 may be a predictive marker of the effect of neoadjuvant chemotherapy for locally advanced uterine cervical cancer.

Neoadjuvant chemotherapy (NAC) followed by hysterectomy may be effective for the treatment of locally advanced uterine cervical cancer and improve patient prognosis. It is important to identify markers that are able to predict whether NAC may be successful. Epidermal growth factor-like domain 7 (EGFL7) regulates vascular sprouting in blood vessel formation.

A case of systemic lupus erythematosus with multiple nodules in the bilateral lungs and vertebrae.

We encountered a case of a middle-aged woman with systemic lupus erythematosus. As the patient had progressive peripheral neuropathy including foot drop, we intended to treat her with intensive immunosuppressive therapy as soon as possible. Pretreatment assessment, however, revealed multiple nodular lesions in the lungs and bones, suggesting disseminated tumor metastasis or miliary tuberculosis.

Pharmacokinetic analyses of carboplatin in a patient with cancer of the fallopian tubes undergoing hemodialysis: A case report.

Opportunities for patients undergoing hemodialysis to receive chemotherapy are increasing. A combination of paclitaxel and carboplatin (TC) is first-line chemotherapy in patients with Müllerian cancer. However, the optimal dose and time interval between the end of carboplatin administration and initiation of hemodialysis remains to be elucidated.

Complete recovery from paraneoplastic anti-NMDAR encephalitis associated with a small ovarian teratoma following a laparoscopic salpingo-oophorectomy: A case report.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a severe but treatment-responsive disorder, initially identified in young women with an ovarian teratoma. Symptoms include mood, behavior and personality irregularities that resemble acute psychosis. The present study reports the rare case of a patient with anti-NMDAR encephalitis and severe neurological symptoms, that exhibited a rapid recovery following a laparoscopic salpingo-oophorectomy.

Sirtuin1 expression predicts the efficacy of neoadjuvant chemotherapy for locally advanced uterine cervical cancer.

Cisplatin-based, cyclic balloon-occluded arterial infusion, neoadjuvant chemotherapy (NAC) has previously been reported to enable hysterectomy in patients with locally advanced cervical cancer. Sirtuin1 (SIRT1) is a nicotinamide adenine dinucleotide (NAD)-dependent histone deacetylase that deacetylates a number of proteins and is overexpressed in several human malignancies. Upregulation of SIRT1 has been reported to induce tumorigenesis and chemoresistance.

Comparison of outcomes between squamous cell carcinoma and adenocarcinoma in patients with surgically treated stage I-II cervical cancer.

To improve our understanding of cervical adenocarcinoma (AD) and evaluate the clinical and pathological variables affecting its prognosis, we retrospectively reviewed the medical records of 455 patients with cervical cancer [International Federation of Gynecology and Obstetrics stage I/II; 91 cases with AD and 364 with squamous cell carcinoma (SCC)] who underwent surgery at our hospital between January, 1995 and August, 2012 and compared the characteristics and prognoses between AD and SCC cases, including age, clinical stage, histological type, lymph node metastasis, lymphovascular space invasion (LVSI), cervical stromal invasion, parametrial invasion, vaginal invasion, corpus invasion, ovarian metastasis and tumor diameter. We used Cox regression analysis to determine independent prognostic factors. AD was found to have a significantly poorer prognosis in all the patients (P=0.
