PURPOSE: Androgen deprivation therapy (ADT) is one of the main strategies to treat prostate cancer (PCa) at various stages of its development. Androgen receptor (AR) antagonists such as enzalutamide are mainstay treatments for castration-sensitive prostate cancer. Though, a majority of patients initially respond to ADT, most will eventually progress to castrate-resistant, due to the development of different mutations on the AR. PCa cells express high telomerase activity, and there is a correlation between the total activity of telomerase and the Gleason score...

PURPOSE: Tumor location (right-sided vs. left-sided) is known to exert a significant influence on the prognosis of primary colorectal cancer (CRC). Given the genetic continuity between primary and metastatic lesions, we aimed to summarize the existing literature on the prognostic implications of primary tumor site as well as to examine the response to chemotherapy by primary tumor location in patients with metastatic CRC (mCRC). METHODS: A structured review of the literature was performed between 6/1/2016-7/1/2016 using the Pubmed database...

The growing number of successfully cured cancer patients has created a new field in oncogenesis. The life expectancy of such patients has increased, however this favorable event may create enough time for epigenetic events to occur which can cause a new carcinognic event, i.e. a secondary malignancy. The terms in use are second primary malignancies as well as therapy-related neoplasms in case the treatment of the first neoplasm is a direct cause. Second primary malignancies can be hematological neoplasms or solid tumors, with solid tumors having higher frequency...

Among non-albicans Candida species, the opportunistic pathogen Candida krusei emerges because of the high mortality related to infections produced by this yeast. The Candida krusei is an opportunistic pathogen presenting an intrinsic resistance to fluconazol. In spite of the reduced number of infections produced by C. krusei, its occurrence is increasing in some groups of patients submitted to the use of fluconazol for prophylaxis. Photodynamic antimicrobial chemotherapy (PACT) is a potential antimicrobial therapy that combines visible light and a nontoxic dye, known as a photosensitizer, producing reactive oxygen species (ROS) that can kill the treated cells...

Thrombopoietin-receptor agonists have been recently introduced for a second-line treatment of immune thrombocytopenia (ITP). Splenectomy has tended to be avoided because of its complications, but the response rate of splenectomy is 60-80% and it has still been considered for steroid-refractory ITP. We performed partial splenic embolization (PSE) as an alternative to splenectomy. Between 1988 and 2013, 91 patients with steroid-resistant ITP underwent PSE at our hospital, and we retrospectively analyzed the efficacy and long-term outcomes of PSE...

This report summarizes the state-of-the-art and controversies around patient selection for deep brain stimulation (DBS) for various conditions. Parkinson's disease (PD): several class I studies have shown superiority of DBS over best medical treatment for advanced PD with fluctuations and further inclusion criteria. One class I study suggests that PD patients with early motor complications might gain more quality of life if operated within 3 years after the onset of fluctuations. The subthalamic nucleus (STN) is still the standard target...

Roberto Ferrara, Laura Mezquita, Benjamin Besse
The treatment paradigm of non-small cell lung cancer (NSCLC) underwent a major revolution during the course of 2017. Immune checkpoint inhibitors (ICIs) brought remarkable improvements in response and overall survival (OS) both in unselected pretreated patients and in untreated patients with PD-L1 expression ≥50%. Furthermore, compelling preliminary results were reported for new combinations of anti-PD-1/PD-L1 agents with chemotherapy or anti-CTLA4 inhibitors. The success of the ICIs appeared to extend to patients with small cell lung cancer (SCLC), mesothelioma or thymic tumors...

OBJECTIVES: We quantified the impact of antibiotics prescribed in primary care for urinary tract infections (UTIs) on intestinal colonisation by ciprofloxacin-resistant (CIP-RE) and extended-spectrum beta-lactamase-producing Enterobacteriaceae (ESBL-PE), while accounting for household clustering. METHODS: Prospective cohort study from January 2011 to August 2013 at primary care sites in Belgium, Poland and Switzerland. We recruited outpatients requiring antibiotics for suspected UTIs or asymptomatic bacteriuria (exposed patients), outpatients not requiring antibiotics (non-exposed patients), and 1-3 household contacts for each patient...

Cancer stem cells (CSCs) have been shown to play a key role in tumor initiation, progression, metastasis, and therapy resistance. Despite their potential clinical importance, the mechanism of CSC regulation is not well understood. Recent evidence suggests that different types of non-coding RNAs (ncRNA), such as microRNA (miRNA) and long non-coding RNA (LncRNA), play a role in regulating CSC growth and replication by modulating transcription factors and downstream signaling pathways activated in CSCs. Here, we review the recent major findings about how they affect stem cell quality acquisition and maintenance in CSCs, as well as metastasis and therapy resistance...

BACKGROUND: The CHAARTED (ChemoHormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer) and STAMPEDE (Systemic Therapy in Advancing or Metastatic Prostate Cancer: Evaluation of Drug Efficacy) trials showed that the addition of docetaxel (D) to androgen deprivation therapy (ADT) prolonged longevity of men with metastatic hormone-sensitive prostate cancer (mHSPC). However, the impact of upfront D on subsequent therapies is still unexplored. As abiraterone acetate (AA) and enzalutamide (E) are the most commonly used first-line treatment for metastatic castration-resistant prostate cancer (mCRPC), we aimed to assess whether they maintained their efficacy after ADT+D versus ADT alone...

OBJECTIVE: Temporal lobe epilepsy (TLE) is a chronic epilepsy syndrome defined by seizures and progressive neurological disabilities, including cognitive impairments, anxiety and depression. Here, human TLE specimens were investigated focusing on the mechanistic target of rapamycin (mTOR) Complex 1 (mTORC1) and Complex 2 (mTORC2) activities in the brain, as both pathways may represent unique targets for treatment. METHODS: Surgically resected hippocampal and temporal lobe samples from therapy-resistant TLE patients were analyzed by Western blotting to quantify the expression of established mTORC1 and mTORC2 activity markers and upstream or downstream signaling pathways involving the two complexes...

Advancements in rapid diagnostics have helped to identify nutritionally variant streptococci (NVS) as an increasing cause of infective endocarditis. This case report highlights the challenges in susceptibility testing and the importance of appropriate empiric treatment for Granulicatella adiacens, as well as considerations for future practice guideline recommendations. Guidelines for treatment of IE caused by NVS are currently limited to patients with native valve disease. We present a patient with presumed prosthetic valve endocarditis caused by Granulicatella adiacens, with clinically relevant resistance to recommended first-line agents (penicillin and ceftriaxone), who was successfully treated with 8 weeks of intravenous (IV) vancomycin...

BACKGROUND: Balloon pulmonary angioplasty (BPA) is an emerging interventional treatment option for chronic thromboembolic pulmonary hypertension (CTEPH). The non-invasive monitoring of CTEPH patients is a clinical challenge. In this study we examined changes in N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients undergoing BPA for inoperable CTEPH and related them to peri-procedural success. METHODS: In this study we analyzed a total of 51 consecutive patients who underwent BPA treatment and completed a 6-month follow-up (6-MFU) between March 2014 and March 2017...

Mycobacterium abscessus lung disease is difficult to treat due to inducible resistance to macrolides. However, 15%-20% of isolates are macrolide susceptible. In 14 patients with macrolide-susceptible M. abscessus lung disease, all isolates had nonfunctional erm(41) gene, and sputum culture conversion rate was achieved in 93% (13/14) following antibiotic therapy.

The widespread occurrence of anthelmintic resistance in equine parasites across the world has led to recommendations of fecal egg count-based parasite programs to reduce treatment intensity and thereby delay further development of resistance as much as possible. The most recent study describing equine parasite control in the United States was conducted 20 years ago, and little is known about current strategies employed. This study was part of the National Animal Health Monitoring Systems (NAHMS) Equine 2015 Study, and aimed to describe equine parasite control strategies in the U...

BACKGROUND: Emerging evidence suggests molecular and phenotypic association between treatment resistance and epithelial-mesenchymal transition (EMT) in cancer. Compared with the well-defined molecular events of miR-200a in EMT, the role of miR-200a in therapy resistance remains to be elucidated. METHODS: Breast cancer cells transfected with mimic or inhibitor for miR-200a was assayed for chemoresistance in vitro. miR-200a expression was assessed by quantitative real-time PCR (qRT-PCR) in breast cancer patients treated with preoperative chemotherapy...

BACKGROUND: Combination antiretroviral therapy efficiently suppresses HIV replication in infected patients, transforming HIV/AIDS into a chronic disease. Viral resistance does develop however, especially under suboptimal treatment conditions such as poor adherence. As a consequence, continued exploration of novel targets is paramount to identify novel antivirals that do not suffer from cross-resistance with existing drugs. One new promising class of targets are HIV protein-cofactor interactions...
