STUDY QUESTION: Does a short abstinence period of only 2 h yield spermatozoa with better motility characteristics than samples collected after 4-7 days? SUMMARY ANSWER: Despite lower semen volume, sperm concentration, total sperm counts and total motile counts, higher percentages of motile spermatozoa with higher velocity and progressiveness were detected in samples obtained after 2 h. WHAT IS KNOWN ALREADY: Most studies that have assessed the effect of abstinence periods on sperm motility parameters in men with a sperm concentration below 15 million/ml have detected a higher percentage of motile spermatozoa in samples obtained after short abstinence periods...

Rising pressure from chronic diseases means that we need to learn how to deal with challenges at a different level, including the use of systems approaches that better connect across fragments, such as disciplines, stakeholders, institutions, and technologies. By learning from progress in leading areas of health innovation (including oncology and AIDS), as well as complementary indications (Alzheimer's disease), I try to extract the most enabling innovation paradigms, and discuss their extension to additional areas of application within a systems approach...

Embryonic stem cells (ESCs) technology has garnered worldwide attention for its therapeutic applications in vivo. Researchers have previously shown that non-viral induced pluripotent stem cells (iPSCs) can be generated from urine. As a potential alternative, Urinary iPSCs (UiPSCs) are highly similar to embryonic stem cells (ESCs) in many aspects such as morphology, expression of pluripotency markers and the capacity to develop into three germ layers in vitro and in vivo. However, the degree of gene expression similarity between iPSCs and ESCs has not been completely elucidated...

The discovery of induced pluripotent stem cells (iPSCs) has revolutionized regenerative medicine. Autologous iPSCs can be generated by introducing 4 stem cell-specific factors (Oct4, Sox2, Klf4, c-Myc) into fibroblasts. iPSCs can propagate indefinitely and differentiate into clinically important cell types including cardiomyocytes, in vitro. The iPSC-derived cardiomyocytes represent a promising source of cells for cell-based therapeutic approaches for cardiac regeneration. However, there are several challenges in the clinical application of iPSCs: tumorigenicity of immature cells, poor survival of the transplanted myocardial cells, and cost and efficacy of this therapeutic approach...

Precision medicine is the application of genotypic and Omics biomarkers to determine the most appropriate, outcome-driven therapy for individual patients. To determine the best choice of therapy, institutions use significant information technology-enabled data from imaging, electronic medical records, sensors in the clinic/hospitals, and wearable sensors to determine treatment response. With genomic profiling, targets to affect a disease course are continuing to be developed. As clonal mutational prevalence continues to be understood, information can be communicated to patients to inform them that resistance is common, requiring collection of more genetic mutations from patients with further biopsies or blood collection...

Telehealth refers to health care interactions that leverage telecommunication devices to provide medical care outside the traditional face-to-face, in-person medical encounter. Technology advances and research have expanded use of telehealth in health care delivery. Physical medicine and rehabilitation providers may use telehealth to deliver care to populations with neurologic and musculoskeletal conditions, commonly treated in both acute care and outpatient settings. Patients with impaired mobility and those living in locations with reduced access to care may particularly benefit...

Multiple myeloma (MM) is a bone marrow plasma cell malignancy characterized by wide clinical presentation and heterogeneous genetic background. Despite the recent advances in patient outcome, new markers are needed for improving risk prediction and choice of a more appropriate therapy. In this perspective, the genetic makeup of MM cells is being better characterized by means of next-generation sequencing (NGS) technologies. Areas covered: The authors discuss how the application of NGS has improved our knowledge of MM biology by discovering its mutational landscape, identifying the operating mutational processes, and revealing the clonal composition of tumors and the dynamics of its evolution; and how this can have important clinical implications in terms of prognostication, therapeutic choices, and response assessment...

We discuss the state of the art and innovative micro- and nanoscale technologies that are finding niches and opening up new opportunities in medicine, particularly in diagnostic and therapeutic applications. We take the design of point-of-care applications and the capture of circulating tumor cells as illustrative examples of the integration of micro- and nanotechnologies into solutions of diagnostic challenges. We describe several novel nanotechnologies that enable imaging cellular structures and molecular events...

The transfusion of platelets is essential for diverse pathological conditions associated with thrombocytopenia or platelet disorders. To maintain optimal platelet quality and functions, platelets are stored as platelet concentrates (PCs) at room temperature under continuous agitation-conditions that are permissive for microbial proliferation. In order to reduce these contaminants, pathogen reduction technologies (PRTs) were developed by the pharmaceutical industry and subsequently implemented by blood banks...

Despite the enormous efforts of the scientific community over the years, effective therapeutics for many (epi)genetic brain disorders remain unidentified. The common and persistent failures to translate preclinical findings into clinical success are partially attributed to the limited efficiency of current disease models. Although animal and cellular models have substantially improved our knowledge of the pathological processes involved in these disorders, human brain research has generally been hampered by a lack of satisfactory humanized model systems...

Personalized medicine is gaining momentum and analytical methods such as MS are ideally situated to provide coherent imaging of human disease. The cancer research field is already starting to benefit from the MS imaging applications; non-cancerous diseases will hopefully enjoy the same success. Often, the way forward is to embrace several techniques, which can complement and verify each other. This approach can be seen as less confrontational as everyone can play a part in the development of a new working practice...

Human tissues are sophisticated ensembles of many distinct cell types embedded in the complex, but well-defined, structures of the extracellular matrix (ECM). Dynamic biochemical, physicochemical, and mechano-structural changes in the ECM define and regulate tissue-specific cell behaviors. To recapitulate this complex environment in vitro, dynamic polymer-based biomaterials have emerged as powerful tools to probe and direct active changes in cell function. The rapid evolution of polymerization chemistries, structural modulation, and processing technologies, as well as the incorporation of stimuli-responsiveness, now permit synthetic microenvironments to capture much of the dynamic complexity of native tissue...

Enrofloxacin (ENRO) is widely used as an antimicrobial drug for treatment of uncomplicated and complicated infections in veterinary medicine. Its bitter taste limits its clinical applications in veterinary. To mask the bitter taste of this drug, double-coated taste-masking microparticles of ENRO (DTME) were prepared through stearic acid solid dispersion and chitosan-alginate microparticle coating technologies. The taste-masking effect was evaluated by pig feeding experiment. Results showed that DTME exhibited a spherical-like shape (170490μm)...

Prostate cancer is one of the most common types of cancer in males. Heterogeneous genomic aberrations may lead to prostate cancer onset, progression and metastasis. This heterogeneity also contributes to the variety in cancer risk and outcomes, different drug responses and progression, observed between individual patients. Classical prognostic factors, including prostate-specific antigen, Gleason Score and clinical tumor staging, are not sufficient to portray the complexity of a clinically relevant cancer diagnosis, risk prognosis, treatment choice and therapy monitoring...

A major objective of 'omics' technologies is to understand genetic causality of complex traits of human diseases. High-throughput omics technologies and their application to medicine open up remarkable opportunities for realising optimised medical treatment for individuals. Because many major breakthrough and discoveries in this field have been driven by the development of new omics technologies, in this review, the authors aim to provide an in-depth description of their underlying principles as a foundation of developing another new omics technology, and to introduce their emerging applications for personalised medicine...

Genomic and medical data sharing is pivotal if the promise of genomic medicine is to be fully realised. Social scientists working in the genomics arena ask the public 'how is the technology working for you?' Empirical studies on attitudes, values and beliefs are incredibly valuable; they offer a voice from those who are, or will be, directly affected. This is paramount if personalised medicine is to be truly personal. An International attitude study, Your DNA, Your Say, uses film to provide background information and an online survey to gather public views on donating one's own personal DNA and medical data for use by others...

Precision medicine carries huge potential in the treatment of many diseases, particularly those with high-penetrance monogenic underpinnings. However, precision medicine through genomic technologies also has ethical implications. We will define allocative, personal, and technical value ('triple value') in healthcare and how this relates to equity. Equity is here taken to be implicit in the concept of triple value in countries that have publicly funded healthcare systems. It will be argued that precision medicine risks concentrating resources to those that already experience greater access to healthcare and power in society, nationally as well as globally...
