The aim of this review is to decipher the major central RAAS mechanisms involved in blood pressure regulation. In addition, paracrine functions of brain RAAS and its role in neuroprotection and cognition are also described in this review.

Thoracic vascular structures often preclude transbronchial access to central lung parenchymal lesions and lymph nodes, thereby necessitating either a surgical or transvascular needle aspiration (TVNA) approach for diagnostic sampling. The aim of this study was to evaluate the safety and efficacy of endobronchial ultrasound (EBUS) TVNA in the diagnosis and staging of mediastinal tumors.

We performed a retrospective analysis of 35 cases of EBUS-TVNA. Cases were reviewed in the Cerner electronic medical records between March 2013 and October 2018. Records were reviewed for patient comorbidities, smoking status, anticoagulation intake, procedural details, sample results, and postprocedural complications.

Thirty-five EBUS-TVNA procedures were reviewed. Twenty-nine of them were performed by traversing the main pulmonary artery or its branches. Three involved transvascular access through the azygous vein, 2 via the brachiocephalic artery and 1 through the superior vena cava. Only 4 patients (11.4%) experienced postprocedural complications, which included mild hemoptysis, moderate hemoptysis requiring epinephrine and saline infusion, acute exacerbation of chronic obstructive pulmonary disease, and a rapid ventricular rate on top of preexisting atrial fibrillation. The yield of TVNA for malignancy was 22 (95.6%) of 23 patients. Overall yield was 31 (88.6%) of 35, with a need for additional intervention in 4 (11.4%) of 35 patients. Mutational analysis was adequate when ordered.

In our single-center experience, the EBUS-TVNA procedure had a high diagnostic yield and was associated with low rates of postprocedural complications. selleckchem Further trials are needed to assess its efficacy compared to more invasive procedures.

We assessed the long-term oncologic safety of nipple-sparing mastectomy (NSM) compared to skin-sparing mastectomy (SSM) for primary breast cancer patients with immediate reconstruction.

Data of stage 0-III primary breast cancer patients undergoing NSM (n= 190) or SSM (n= 729) from June 2006 to December 2012 were retrospectively collected. Nipple-tumor distance (NTD) was measured on pretreatment mammography, magnetic resonance imaging, or ultrasonography findings. NSM patients with NTD< 1 cm were excluded. Locoregional recurrence (LRR) rates were compared between groups. Disease-free survival (DFS) and overall survival (OS) according to surgical procedure were assessed.

The median (range) follow-up period for NSM and SSM was 71 (10-131) months and 79 (9-140) months, respectively. LRR developed in 11 patients with invasive ductal carcinoma (5.8%) for NSM and 44 (42 in patients with invasive ductal carcinoma and 2 in patients with ductal carcinoma-in-situ) (6.0%) for SSM. Hormone receptor and HER2 status were not associated with LRR in either group. DFS and OS rates did not differ between groups (DFS 89.3% for NSM, 89.3% for SSM, P= .87; OS 98.4% for NSM, 94.5% for SSM, P= .43).

NSM with immediate reconstruction was as safe as SSM for primary breast cancer with respect to prognosis and local control, regardless of the presence of invasive carcinoma or breast cancer subtype.

Leptomeningeal metastasis (LM) is associated with a grave prognosis in breast cancer (BC) and can be controlled with a ventriculoperitoneal shunt (VPS). Information regarding LM and VPS based on intrinsic subtype is limited; thus, we investigated the clinical outcomes of BC treated with VPS.

The present retrospective study comprised 70 patients diagnosed with LM who received a VPS. The patients were divided into 4 groups based on BC subtype hormone receptor (HR)

, and triple negative BC (TNBC).

The most common indications for VPS were uncontrolled intracranial pressure (57.1%) and uncontrolled headache (55.7%), which improved in 54 (77.1%) of 70 patients after VPS. The median overall survival (OS) after brain or LM and overall survival after VPS were 7.6 and 2.3 months, respectively. Anti-HER2 treatment was a significant prognostic factor for better OS after brain or LM based on multivariate analysis (hazard ratio, 0.15; 95% confidence interval, 0.04-0.57; P= .005), whereas TNBC was correlated with shorter OS after central nervous system metastasis (hazard ratio, 2.82; 95% confidence interval, 1.46-5.48; P= .002).

There were significant differences in clinical outcome based on the intrinsic subtype of patients with BC with LM who received a VPS. Anti-HER2 treatment in patients with HER2

BC was associated with better survival in patients with metastatic BC with VPS insertion compared with those without. Survival of metastatic BC with VPS remained poor, especially in the TNBC subgroup.

In the polar oceans, a subset of large lipid-storing copepods occupy central positions in the food web because of their important role in linking phytoplankton and microzooplankton with higher trophic levels. In this paper, we generated a high-quality de novo transcriptome for Rhincalanus gigas, the largest-and among the most abundant-of the Southern Ocean copepods. We then conducted transcriptional profiling to characterize the developmental transition between late-stage juveniles and adult females. We found that juvenile R. gigas substantially upregulate lipid synthesis and glycolysis pathways relative to females, as part of a developmental gene expression program that also implicates processes such as muscle growth, chitin formation, and ion transport. This study provides the first transcriptional profile of a developmental transition within Rhincalanus gigas or any endemic Southern Ocean copepod, thereby extending our understanding of copepod molecular physiology.
