Primary pulmonary lymphoma (PPL) is a rare extranodal lymphoma originating from the lung, accounting for 0.5-1.0% of primary lung malignant tumors. Previous case reports or cohort studies included a limited sample size; therefore, the understanding of the disease remains inadequate, and clinical data regarding PPL are limited.

Patients with PPL diagnosed histologically and radiologically between January 2000 and December 2019 at our center were retrospectively analyzed.

In total, 90 consecutive cases were included in this research. Forty-seven (52.2%) patients were female, and the median age was 54 years old. Non-Hodgkin's lymphoma (PPNHL) was the most common type of PPL (71/90, 78.9%), and mucosa-associated lymphoid tissue (MALT) lymphoma was the most common pathological subtype of PPNHL (56.3%) followed by diffuse large B-cell lymphoma (DLBCL) (32.4%). Thirty-nine (43.3%) patients underwent surgical treatment, and the others received chemotherapy alone or combined with radiotherapy. The estimated 5-yeactor for PPL.
Primary lung cancer with severe central airway obstruction (CAO) is often life-threatening. In this study, we investigated the clinical efficacy and safety of cisplatin plus recombinant human endostatin (rh-endostatin) intratumoral injection in treatment of malignant central airway obstruction (MCAO) caused by primary squamous cell lung cancer.

We retrospectively analyzed patients with MCAO caused by primary squamous cell lung cancer treated with and without bronchoscopic intratumoral injection of cisplatin plus rh-endostatin between January 2007 and June 2016.

A total of 206 patients received cisplatin plus rh-endostatin intratumoral injection, and 113 without injection. Dyspnea grade, degree of stenosis, quality of life and lung function of all patients were significantly improved at 1 week after treatment compared with baseline. Both groups achieved good airway patency (97.1%
. 93.8%, P=0.156). Followed up at 2 months, all parameters were improved in the injection group compared with baseline, while no statistical differences were observed in the non-injection group (P>0.05). The injection group achieved airway patency in 155 (75.2%) of 206 patients, which was significantly superior to the non-injection group [20 (17.7%) of 113, P<0.001]. In addition, the restenosis rate of the injection group was lower compared with the non-injection group (22.5%
. 81.1%, P<0.001, respectively). No serious complications were observed in two groups.

Cisplatin plus rh-endostatin intratumoral injection is effective and safe for the therapy of MCAO caused by primary squamous cell lung cancer.

Guidelines on the diagnosis and management of hypertrophic cardiomyopathy (HCM) recommend that septal myectomy be performed by experienced operators. However, the impact of operator volume on surgical treatment outcomes for isolated HCM has been poorly investigated.

From 2002 to 2014, 435 consecutive patients with isolated HCM undergoing myectomy at the Fuwai Hospital were retrospectively enrolled. All 29 surgeons were divided into beginner surgeons (operator volume ≤20) and experienced surgeons (operator volume >20) according to the guidelines for the diagnosis and treatment of HCM. Propensity score matching of patients in the two groups was performed.

Baseline differences included advanced New York Heart Association classification and older age in the experienced surgeon group. After matching, in the beginner surgeon group (107 cases), residual obstruction (18.7%
0.9%, P<0.001) was more common, and the postoperative left ventricular outflow tract pressure gradient (20.7±15.1
14.3±7.4 mmHg, P<0.001) was higher than that of the experienced surgeon group. In the experienced surgeon group (107 cases), the incidence of mitral valve replacement (1.9%
11.2%, P<0.001) and permanent pacemaker implantation (1.9%
3.7%, P<0.001) was significantly lower than that in the beginner surgeon group. However, there was no difference in procedural mortality (1.9%
1.9%) between the two groups.

Operator volume is an important factor in achieving better obstruction obliteration after septal myectomy in patients with isolated HCM.

One of the most frequent complications of coronary artery bypass grafting (CABG) is pleural effusion. Limited previous studies have found post-CABG pleural effusion to be associated with increased length-of-stay and greater morbidity post-CABG. selleck compound Despite this the associations of this common complication are poorly described. This study sought to identify modifiable risk factors for effusion post-CABG.

A retrospective cohort study of prospectively collected data assessed patients who underwent CABG over two-years. Data was collected for risk factors and sequelae related to pleural effusion requiring drainage.

A total of 409 patients were included. Average age was 64.9±10.2 years, 330 (80.7%) were male. 59 (14.4%) patients underwent drainage of pleural effusion post-CABG. Effusions were drained on average 9.9±8.4 days post-CABG. Earlier removal of drain tubes and removal near time of extubation were associated with development of pleural effusion. Post-CABG pleural effusion was associated with post-operativconsidered in the presence of pleural effusion. Modifiable associated factors in the management of drains that may contribute to accumulation of pleural effusion include early removal of chest drains, higher outputs and removal during or close to mechanical ventilation. Further research is required to assess how adjusting these modifiable factors can decrease rates of effusion post-operatively.
Tumor mutational burden (TMB) has been identified as one of the predictors for the response to anti-programmed cell death-1 (anti-PD-1) antibody therapy and reported to correlate with smoking history in lung adenocarcinoma. However, in squamous cell carcinoma of the lung, the association between TMB and clinicopathological background factors, such as smoking history, has not been reported, including in our previous study. The mutational signature is a tool to identify the mutagens that are contributing to the mutational spectrum of a tumor by investigating the pattern of DNA changes. Here, we analyzed the mutational signature in lung squamous cell carcinoma to identify mutagens affecting the TMB.

Seven representative mutational signatures including signature 7 (SI7) [ultraviolet (UV)-related], SI4 (smoking), SI6/15 [mismatch repair (MMR)], SI2/13 [apolipoprotein B mRNA editing enzyme, catalytic polypeptide-like (APOBEC)], and SI5 (clock-like) were analyzed in Japanese patients with lung squamous cell carcinoma (n=67) using data generated by next-generation sequencing consisting of a 415-gene panel.
