We analysed the clinical features and diagnostic workup of patients presenting with haemoptysis to an Italian teaching hospital to derive an easy-to-use clinical score to guide risk stratification and initial management in the emergency department (ED). We retrospectively reviewed clinical records of consecutive patients with haemoptysis over 1 year. A pre-specified set of variables, including demographic data, vital signs, type of expectorate (pure blood vs. blood-streaked sputum), comorbidities, and diagnostic tests and treatments was originally registered...

BACKGROUND: OncotypeDX, a multi-gene expression assay, has been incorporated into clinical practice as a prognostic and predictive tool. However, its use in resource-constrained international healthcare systems is limited. Here we develop and validate a simplified model using clinicopathologic criteria to predict OncotypeDX score. METHODS: Patients with estrogen receptor (ER) and/or progesterone receptor (PR)-positive and HER2-negative invasive ductal carcinoma for whom the OncotypeDX test was successfully performed between 09/2008 and 12/2011 were retrospectively identified...

Neurodegenerative diseases are disorders related to the degeneration of central neurons that gradually lead to various, severe alterations of cognitive and/or motor functions. Currently, for no such diseases does any pharmacological treatment exist able to arrest its progression. Riluzole (1) is a small molecule able to interfere with multiple cellular and molecular mechanisms of neurodegeneration, and is the only approved treatment of amyotrophic lateral sclerosis (ALS), the progression of which proved to significantly slow, thus increasing somewhat average survival...

Solid papillary carcinoma with reverse polarity (SPCRP) is a rare breast cancer subtype with an obscure etiology. In this study, we sought to describe its unique histopathologic features and to identify the genetic alterations that underpin SPCRP using massively parallel whole-exome and targeted sequencing. The morphologic and immunohistochemical features of SPCRP support the invasive nature of this subtype. Ten of 13 (77%) SPCRPs harbored hotspot mutations at R172 of the isocitrate dehydrogenase IDH2, of which 8 of 10 displayed concurrent pathogenic mutations affecting PIK3CA or PIK3R1 One of the IDH2 wild-type SPCRPs harbored a TET2 Q548* truncating mutation coupled with a PIK3CA H1047R hotspot mutation...

Prion diseases are serious, not curable neurodegenerative disorders caused by the accumulation of the misfolded protein PrP(Sc) that represents the pathological variant of the normally folded cellular protein PrP(C). Molecules that bind the cellular isoform PrP(C) preventing its misfolding, could arrest the progression of pathological conditions related to the abnormal PrP protein. In this context, by combining 3D-QSAR model, derived from pharmacophore-based alignment, with molecular docking procedures and physico-chemical properties prediction we have developed a virtual screening protocol to find novel chemicals able to prevent PrP(C) misfolding...

D3 receptors represent a major focus of current drug design and development of therapeutics for dopamine-related pathological states. Their close homology with the D2 receptor subtype makes the development of D3 selective antagonists a challenging task. In this review, we explore the relevance and therapeutic utility of D3 antagonists or partial agonists endowed with multireceptor affinity profile in the field of central nervous system disorders such as schizophrenia and drug abuse. In fact, the peculiar distribution and low brain abundance of D3 receptors make them a valuable target for the development of drugs devoid of motor side effects classically elicited by D2 antagonists...

BACKGROUND/AIMS: The normal lung ultrasound (US) pattern during a regular pregnancy has not been evaluated extensively in the current literature. Pregnancy-related changes in the respiratory tract affect maternal predisposition to several respiratory complications; consequently, it is important to differentiate between a physiologic pattern during pregnancy and a pathologic lung pattern, due to respiratory failure. The goal of our study was to assess the normal US lung pattern in women without known comorbidities in the last weeks of pregnancy...

Direct hemoperfusion with polymyxin B (PMX-DHP) is an extracorporeal treatment to add to conventional therapy during unresponsive endotoxic septic shock. So far, only heparin has been used as an anticoagulant during polymyxin B therapy. We present a case report of a postsurgical septic patient treated with 2 cycles of PMX-DHP using citrate anticoagulation. Monitoring of serum calcium, postcartridge calcium, and acid-base balance was performed. The treatments were accomplished without complications. To our knowledge, this is the first published report on the use of citrate anticoagulation during PMX-DHP...

In early-stage breast cancer, the degree of tumor-infiltrating lymphocytes (TIL) predicts response to chemotherapy and overall survival. Combination immunotherapy with immune checkpoint antibody plus tumor cryoablation can induce lymphocytic infiltrates and improve survival in mice. We used T-cell receptor (TCR) DNA sequencing to evaluate both the effect of cryoimmunotherapy in humans and the feasibility of TCR sequencing in early-stage breast cancer. In a pilot clinical trial, 18 women with early-stage breast cancer were treated preoperatively with cryoablation, single-dose anti-CTLA-4 (ipilimumab), or cryoablation + ipilimumab...

PURPOSE: To assess the safety and tolerability of preoperative cryoablation-mediated tumor antigen presentation and/or ipilimumab-mediated immune modulation in women with operable breast cancer. EXPERIMENTAL DESIGN: In this pilot study, 19 women with breast cancer for whom mastectomy was planned were treated with preoperative tumor cryoablation (n = 7), single-dose ipilimumab at 10 mg/kg (n = 6), or both (n = 6). The primary outcome for this pilot study was safety/tolerability as defined as freedom from delays in pre-planned, curative-intent mastectomy...

AIM: Histone deacetylases (HDACs) regulate the expression and activity of numerous proteins involved in the initiation and progression of cancer. Currently, three hydroxamate-containing HDAC pan-inhibitors have been approved as antitumor agents. RESULTS: We herein present the development of a series of novel phenylpyrrole-based derivatives stemmed from combined computational and medicinal chemistry efforts to rationally modulate HDAC1/6 isoform selectivity. In vitro activity on HDAC1 and HDAC6 isoforms and the effects of selected analogs on histone H3 and α-tubulin acetylation levels were determined...

BACKGROUND: A 21-gene expression assay (Oncotype DX recurrence score [RS]) that uses reverse transcriptase-polymerase chain reaction is used clinically in patients with early-stage, estrogen receptor (ER)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast carcinoma (ER+/HER2- BC) to determine both prognosis with tamoxifen therapy and the usefulness of adding adjuvant chemotherapy. Use of the assay is associated with reductions in overall chemotherapy use. The current study examined the treatments and outcomes in patients with low RS...

CONTEXT: -Sentinel lymph node biopsy has been established as the new standard of care for axillary staging in most patients with invasive breast carcinoma. Historically, all patients with a positive sentinel lymph node biopsy result underwent axillary lymph node dissection. Recent trials show that axillary lymph node dissection can be safely omitted in women with clinically node negative, T1 or T2 invasive breast cancer treated with breast-conserving surgery and whole-breast radiotherapy...

PIK3CA, which encodes the p110α subunit of PI3K, is frequently mutated and oncogenic in breast cancer. PI3Kα inhibitors are in clinical development and despite promising early clinical activity, intrinsic resistance is frequent among patients. We have previously reported that residual downstream mTORC1 activity upon treatment with PI3Kα inhibitors drives resistance to these agents. However, the mechanism underlying this phenotype is not fully understood. Here we show that in cancer cells resistant to PI3Kα inhibition, PDK1 blockade restores sensitivity to these therapies...

Genetic screening identifies the atypical tetraspanin TM4SF1 as a strong mediator of metastatic reactivation of breast cancer. Intriguingly, TM4SF1 couples the collagen receptor tyrosine kinase DDR1 to the cortical adaptor syntenin 2 and, hence, to PKCα. The latter kinase phosphorylates and activates JAK2, leading to the activation of STAT3. This non-canonical mechanism of signaling induces the expression of SOX2 and NANOG; sustains the manifestation of cancer stem cell traits; and drives metastatic reactivation in the lung, bone, and brain...
