The objective of the study was to measure patient attitudes and experience of information received during drug counselling for rheumatoid arthritis (RA) medications. This is a cross-sectional UK postal questionnaire study. Three RA patient groups-disease-modifying antirheumatic drugs (DMARDs) only, first anti-tumour necrosis factor (anti-TNF) and failed anti-TNF-were sent postal questionnaires. Data on patient history/demographics, drug counselling experience, knowledge of drug side effects, attitudes to vaccinations, cancer screening and blood borne virus testing was collected; 264/679 (39%) patients responded (median age 65 years, 66% female, median disease duration 15 years)...

INTRODUCTION: Although the US Preventive Services Task Force recommends against routine prostate cancer screening with prostate-specific antigen (PSA) testing, specialty organizations support screening via shared decision making between providers and selected patients. While discussions about advantages and disadvantages of testing are a feature of patient-centered care, it is unclear how provider recommendations and the presence of a personal doctor influence testing in the presence of such discussions...

REVIEW
Juan D Garisto, Laurence Klotz
Prostate cancer is the most common malignancy affecting men. There has been a nearly 70% increase in new prostate cancer cases, mostly classified as low risk, that have been diagnosed in early stages as a consequence of prostate-specific antigen (PSA) screening. Data regarding the natural history of this disease confirm the clinical insignificance of low-grade prostate cancer, which is associated with scant or no metastatic dissemination. Active surveillance is a conservative management approach, conducted for those patients with "low-risk" or "favorable-risk" disease, which avoids long-term adverse effects on the patient's quality of life...

As guidelines for prostate cancer screening have changed from an annual screening recommendation starting at age 50 to discussing the benefits and harms of screening with health care providers, it is necessary to examine other types of factors that are important to prostate cancer screening decisions among African American men. Perceived risk of developing cancer has been shown to predict cancer control behaviors and is lower among African Americans. We characterized perceived risk of developing prostate cancer among African American men from November 2009 to 2011 and evaluated the relationship between prostate cancer risk perceptions and sociodemographic characteristics, health care experiences, and knowledge and exposure to health information about cancer...

This issue presents research on the types of decisions that are required daily in family medicine. Patients often make these health decisions, and family physicians help patients with these decisions daily. Patients and their family physicians discuss when to quit screening for colon cancer, which treatment to choose for localized prostate cancer, when to test for pertussis when a cough is present, whether to take prescribed medications, how to complete more preventive services, and how to understand the "new genetics", and family physician use of telehealth...

PURPOSE: Technology could transform routine decision making by anticipating patients' information needs, assessing where patients are with decisions and preferences, personalizing educational experiences, facilitating patient-clinician information exchange, and supporting follow-up. This study evaluated whether patients and clinicians will use such a decision module and its impact on care, using 3 cancer screening decisions as test cases. METHODS: Twelve practices with 55,453 patients using a patient portal participated in this prospective observational cohort study...

A lack of appropriate diagnostic tools for prostate cancer has led to overdiagnosis and over treatment. In a recent publication in the New England Journal of Medicine, Hamdy et al showed no difference in the outcomes of patients that had undergone either radical prostatectomy, radiotherapy, or active monitoring. In an effort to enhance clinical stratification, the development of improved, more accurate diagnostic tools is actively being pursued. Herein, we explore recent advances in prostate cancer screening, including biomarker assays, genetic testing, and specialized fields, such as mathematical oncology...

The forkhead box (FOX) transcription factor is a family of tumor suppressors that negatively regulates the tumorigenesis activity of prostate cancer; stabilization of FOX-DNA complex architecture has been recognized as a new and promising strategy for sensitizing cancer chemotherapy. Here, we described a systematic method that combined in silico analysis and in vitro assay to investigate the intermolecular interaction between FOX DNA-binding domain (DBD) and its cognate DNA partner. The structural and energetic information harvested from the molecular investigation were used to guide high-throughput virtual screening against a structurally diverse, nonredundant library of natural product compounds, aiming at discovery of novel small-molecule medicines that can conformationally stabilize and promote FOX-DNA recognition and interaction...

BACKGROUND: Compliance rates for colorectal cancer (CRC) screening are much lower than those desired. Appropriate information on CRC risks and screening methods is supposed to stimulate motivation for screening. We aimed to identify parameters associated with the decision for CRC screening and colonoscopy in a population expected to have high awareness of disease prevention. METHODS: In a single-center, cross-sectional study, we used an anonymous questionnaire (AQ) to record the demographics, habits and screening behavior for cancers and other common diseases of all employees older than 50 years in our hospital...

The incidence of prostate cancer is increasing rapidly in China, the clinical stage of prostate cancer patients is comparatively late and the overall survival rate is inferior to that reported in the developed countries. Prostate cancer screening is an effective measure to reduce the risk of death through early detection. In order to identify the best way of prostate cancer screening in China, the Chinese Anti-Cancer Association Genitourinary Cancer Committee Prostate Cancer Working Group reviewed all published data concerning the benefits and harms of screening for prostate caner and created the consensus...

Recent studies have suggested that selective targeting of overexpressed enzymes in cancer cells by small molecules that induce the formation of reactive oxygen species (ROS) could be a viable approach in cancer therapy. One such example is the inactivation of ubiquitin specific protease-2 (USP2)-an emerging drug target to combat prostate cancer-by β-lapachone, which has been identified to involve oxidation of the catalytic cysteine's thiol residue to sulfinic acid. A rational design of β-lapachone analogs with improved activity requires a much better understanding of the variables that determine ROS production by this class of molecules...

INTRODUCTION: The prostate-specific antigen (PSA) screening test is controversial and can result in both over-diagnosis and over-treatment. Recently, the Canadian Task Force on Preventive Health Care (CTFPHC) has recommended against routine screening for prostate cancer. We sought to determine how the CTFPHC has impacted the practice patterns among family physicians in the North Simcoe Muskoka (NSM) Local Health Integration Network (LHIN). MATERIALS AND METHODS: We surveyed all 439 family physicians within the NSM LHIN as well as 21 residents of the Family Medical Teaching Unit...

The Italian national health system provides screening to detect breast, colorecatal and cervical cancers, however, population adherence is not as high as expected. Smartphones and their applications (apps) could be used as a tool to communicate with the population and to help improve adherence. The aim of this study was to analyze the features and functions of smartphone applications aimed at secondary prevention of oncological diseases. In February 2016, we reviewed online app stores, using specific key-words, to search for available apps for cancer screening...

BACKGROUND: Recently, researchers have faced the challenge of conflicting recommendations for online versus traditional methods to recruit and interview older, sexual minority men. Older populations represent the cohort least likely to be online, necessitating the use of traditional research methods, such as telephone or in-person interviews. By contrast, gay and bisexual men represent a population of early adopters of new technology, both in general and for medical research. In a study of older gay and bisexual men with prostate cancer, we asked whether respondents preferred online versus offline methods for data collection...

BACKGROUND: The use of prostate cancer screening tools that take into account relevant prebiopsy information (ie, risk calculators) is recommended as a way of determining the risk of cancer and the subsequent need for a prostate biopsy. This has the potential to limit prostate cancer overdiagnosis and subsequent overtreatment. mHealth apps are gaining traction in urological practice and are used by both practitioners and patients for a variety of purposes. OBJECTIVE: The impetus of the study was to design, develop, and assess a smartphone app for prostate cancer screening, based on the Rotterdam Prostate Cancer Risk Calculator (RPCRC)...

The aim of this study was to develop nomograms for predicting prostate cancer and its zonal location using prostate-specific antigen density, prostate volume, and their zone-adjusted derivatives. A total of 928 consecutive patients with prostate-specific antigen (PSA) less than 20.0 ng/mL, who underwent transrectal ultrasound-guided transperineal 12-core prostate biopsy at West China Hospital between 2011 and 2014, were retrospectively enrolled. The patients were randomly split into training cohort (70%, n = 650) and validation cohort (30%, n = 278)...
