Of the 24 surgeries of SPC, 14 surgeries (58.3%) had a history of two or more ipsilateral pneumothoraces, and 11 surgeries (45.8%) had a history of ipsilateral pleural procedures before SPC. Sixteen ...surgeries (66.6%) in 12 patients received treatment of sirolimus after SPC (sirolimus group). With a median follow-up time of 69.0 months after SPC, four surgeries (16.6%) in three patients had a postoperative recurrence, and the 5-year recurrence-free survival (RFS) after SPC was 82.9%. In patients with postoperative recurrence, serum level of vascular endothelial growth factors D was significantly higher than that in those with non-recurrence (3260.5 vs. 892.7 pg/mL, p = 0.02), and the rate of sirolimus treatment in the recurrence group was significantly lower than that in the no-recurrence group (0 vs. 80%, p = 0.006). The log-rank test showed that the RFS of the sirolimus group (sirolimus use after SPC) was significantly better than that of the non-sirolimus group (p = 0.001), and no significant difference was observed for other factors. We first reported sirolimus might effectively suppress the recurrence of pneumothoraces in LAM patients who received SPC. Sirolimus induction after SPC (TPC or mTPC) might be a feasible option for frequent pneumothorax in LAM.
Abstract Background Rapid eye movement (REM) sleep behavioral disorder (RBD), orthostatic hypotension (OH), and cardiac sympathetic denervation were commonly observed in PD and are related in both ...the premotor and motor periods. This study is intended to evaluate if the OH and cardiac sympathetic denervation found in PD are associated with RBD. Methods Among 94 non-medicated and mild PD patients, 53 had RBD. Orthostatic vital signs and ambulatory 24-hour blood pressure values were recorded.123 I-metaiodobenzylguanidine (MIBG) cardiac scintigraphy as obtained in all patients. The association between orthostatic hypotension, supine hypertension, nocturnal hypertension, non-dipping, myocardial MIBG uptake, and RBD was analyzed. Results RBD was associated with orthostatic hypotension. Patients with RBD had higher systolic blood pressure changes during orthostasis and lower myocardial MIBG uptake than patients without RBD and controls. Patients with OH also had lower mean H/M ratios those in the non-OH group. Conclusion This study showed that RBD was closely associated with OH and cardiac sympathetic denervation in patients with early and mild PD. The result also suggests that impaired cardiac sympathetic innervation could be the mechanism behind OH in PD. This association may be closely correlated with Braak alpha-synuclein pathogenetic sequences, which would account for the clinical spectrum of PD.
This study assessed epidemiologic data and clinical outcomes, including venous thromboembolism (VTE) recurrence and bleeding events, in patients with cancer-associated VTE, and assessed factors ...associated with clinical outcomes. Data were extracted from retrospective medical-chart review of adult patients diagnosed with cancer-associated deep vein thrombosis or pulmonary embolism who received anticoagulation treatment for ≥3 months. Patients were classified by: low-molecular-weight heparin (LMWH), direct oral anticoagulants (DOACs), and other anticoagulants. First VTE recurrence and bleeding events, and factors associated with their occurrence, were assessed during the initial 6 months of treatment. Overall, 623 patients (age: 63.7 ± 11.3 years, 49.3% male) were included (119, 132, and 372 patients in LMWH, DOACs and other anticoagulants groups, respectively). The cumulative 6-month incidence of VTE recurrence was 16.6% (total), 8.3% (LMWH), 16.7% (DOACs), and 20.7% (other); respective bleeding events were 22.5%, 11.0%, 12.3%, and 30.7%). VTE recurrence and bleeding rates differed only between LMWH and other anticoagulants (HR 2.4, 95% CI: 1.2-5.0 and 3.6, 1.9-6.8, respectively). These results highlight the importance of initial VTE treatment choice for preventing VTE recurrence and bleeding events. LMWH or DOACs for ≥3 months can be considered for effective VTE management in cancer patients.
Well‐differentiated papillary mesothelioma (WDPM) is a rare, distinct tumor consisting of mesothelial cells with a papillary architecture, bland cytological features, and a tendency toward ...superficial spread without invasion. Rare cases with superficial invasion are termed WDPM with invasive foci. We report a case of solitary WDPM with invasive foci in the pleura. A 61‐year‐old woman presented with a lung adenocarcinoma. A small papillary lesion measuring 29 × 10 × 8 mm was incidentally found in the parietal pleura during a lobectomy for the lung adenocarcinoma. The fibrovascular core of the small papillary lesion was surrounded by a single layer of cuboidal cells with mild to moderate atypia and large nucleoli. Atypical mesothelial cells focally invaded the submesothelial layer. The cells of the papillary lesion were positive for cytokeratins and mesothelial markers. The Ki67 index was <1 %. The lesion did not show p16 loss on fluorescence in situ hybridization. We could not detect atypical mesothelial cells in the specimen from an extrapleural pneumonectomy. WDPM with invasive foci is prone to multifocality; however, our case represents a solitary case in the pleura.
This report describes the case of a 23-year-old man with a mediastinal teratoma. Five months before admission, a chest radiograph during a routine health checkup was normal. Four months before ...admission, the patient developed sudden onset of mild right-sided chest pain. He gradually developed dyspnea and was admitted to our hospital. Computed tomography revealed a giant tumor that was markedly compressing the right atrium. Urgent surgery was performed, and a ruptured, benign mature teratoma was diagnosed. Mature mediastinal teratomas are benign tumors, but they can rupture and have the potential to grow rapidly, potentially leading to life-threatening complications.
Objectives: Bazedoxifene was found to be effective and well tolerated for the treatment and prevention of osteoporosis in postmenopausal women. This post-marketing surveillance study (PMSS) examined ...the safety of bazedoxifene in postmenopausal Korean women with osteoporosis, in a real-world setting.
Methods: This PMSS was conducted from 2013 to 2017. A total of 3,423 subjects from 68 centers were enrolled and monitored for about 3 months (± 2 weeks). Bazedoxifene was prescribed at a dose of 20 mg/day. The safety of bazedoxifene was evaluated based on the number and nature of adverse events (AEs), serious AEs (SAEs), adverse drug reactions (ADRs) and serious ADRs (SADRs) in routine medical practice.
Results: The mean age of study subjects was 69.51 years. The incidence of AEs and ADRs was 6.11% and 3.86%, respectively, and significantly decreased with increasing age (p= 0.0007). AE and ADR rates with bazedoxifene treatment of 3 months or more were significantly lower than those of less than 3 months (AE, 3.64% vs 30.00%, p < 0.0001; ADR, 1.74% vs 24.38%, p < 0.0001).
Conclusion: In this study, bazedoxifene was well tolerated in the management of postmenopausal osteoporosis in Korean women, including those aged 70 years or more.
Background:
In recent years, the anti-programmed cell death 1 (PD-1) drug pembrolizumab (Keytruda) was approved for treatment of unresectable advanced non-small cell lung cancer (NSCLC) as first- or ...second-line therapy depending on the clone 22C3-programmed death-ligand 1 (PD-L1) immunohistochemical expression score by the companion diagnostic assay. We herein evaluated 22C3-PD-L1 expression of NSCLC in a single institution experience and compared it with clinicopathologic features.
Materials and methods:
We assessed 22C3-PD-L1 expressions of 411 patients with NSCLC from our institution, including in past specimens. Programmed death-ligand 1 immunohistochemistry (IHC) testing was performed using the PD-L1 clone 22C3 pharmDx kit (Agilent Technologies/Dako, Carpinteria, CA, USA). Patients were separated into 3 groups with <1% (no expression), 1% to 49% (low expression), or ⩾50% (high expression) positive tumor cells.
Results:
In all, 137 patients (33%) did not express PD-L1, 155 (38%) showed low expression, and 119 (29%) demonstrated high expression. Archival samples showed lower PD-L1 expression than that of recent samples, and the ratios of no expression case significantly increased by using paraffin blocks embedded particularly in more than 4 years ago. Programmed death-ligand 1 positivity was significantly associated with male sex, smoking, higher tumor grade, squamous cell carcinoma in histologic type, wild-type EGFR, and ALK rearrangement positive.
Conclusions:
The rate of 22C3-PD-L1 expression of NSCLC detected in this study was similar to the frequencies of the previous reports, although the ratio of expression case decreased when using old paraffin blocks.
The
fluorescence in situ hybridisation (FISH) method is the examination essential for pathological diagnosis and choice of molecular-targeted therapy in
-rearranged lung cancer. Here, for detection ...of
gene rearrangement in patients with lung cancer, we evaluated the rapid FISH technology (
SureFISH), a newly developed assay for the automated staining platform Dako Omnis, using 21 formalin-fixed paraffin-embedded (FFPE) samples. All cases could be evaluated with the SureFISH method. SureFISH provided excellent quality signals without any background staining. The SureFISH assay was able to offer a rapid turnaround time (approximately 3.5 hours) and was 100% concordant with prior Vysis FISH results in our laboratory.
Abstract Background Impaired renal function and proteinuria have been associated with cognitive impairment and dementia. Chronic kidney disease is considered to be an independent risk factor for Lewy ...body spectrum disorders (LBD). However, few studies have mentioned an association between proteinuria and cognition in LBD. We investigated the relationship between proteinuria and cognitive dysfunction in patients with Parkinson's disease (PD) and dementia with Lewy bodies (DLB). Methods Among 186 patients with LBD, 53 had PD-normal cognition (PD-NC), 76 had PD-mild cognitive impairment (PD-MCI), 43 had PD-dementia (PDD) and 14 had DLB. The urine protein/creatinine ratio was calculated using the spot urine test and brain magnetic resonance scans was obtained in all patients. Results The urine protein/creatinine ratio was significantly higher in patients with PDD and DLB than in those with PD-MCI, PD-NC patients and healthy controls, and was correlated with white matter hyperintensities on magnetic resonance imaging. All abnormal neuropsychological test results were associated with increased urine protein/creatinine ratio. After controlling for age, education, symptom duration, diabetes mellitus, hypertension, and parkinsonian motor severity, the urine protein/creatinine ratio was significantly associated with decreased cognition. Conclusion The urine protein/creatinine ratio was associated with cognitive status in LBD. These finding suggests that increased protein excretion is associated with cognitive dysfunction in patients with LBD.
