F Thieme, K U Ludwig
In the past decade, medical genetic research has generated multiple discoveries, many of which were obtained via genome-wide association studies (GWASs). A major GWAS finding is that the majority of risk variants for complex traits map to noncoding regions. This has resulted in a paradigm shift in terms of the interpretation of human genomic sequence variation, with more attention now being paid to what was previously termed "junk DNA." Translation of genetic findings into biologically meaningful results requires 1) large-scale and cell-specific efforts to annotate non-protein-coding regions and 2) the integration of comprehensive genomic data sets...

: Ketamine's history begins in the 1950s in Detroit, Michigan, at Parke-Davis Laboratories. On 26 March 1956, Harold V. Maddox synthesised phencyclidine or PCP. Domino studied PCP effects in animals and in 1958, Greifenstein made the first trials of PCP in humans under the name of Sernyl. Sernyl did not cause depression of cardiovascular and respiratory functions, but elicited severe excitation with a very prolonged postoperative recovery. Because of its psychedelic effects, it became a street drug under the name of 'angel dust' and was placed on schedule II of Federal Controlled Substance Act (CSA) in 1978...

PURPOSE OF REVIEW: The present study discusses the utilization of neuraxial drug delivery (NDD) for the management of cancer pain, based on recent trials, reviews, and guidelines with a focus on cost analysis. RECENT FINDINGS: Almost all recent publications suggest that more stringent research is needed to improve evidence on NDD, particularly as conflicting reports exist regarding cost effectiveness of drug delivery systems. The combination of local anesthetics and opioids, with or without clonidine, continues to be reported as beneficial with the utilization of patient controlled systems providing an advantage over continuous ones...

Medical imaging can visualize characteristics of human cancer noninvasively. Radiomics is an emerging field that translates these medical images into quantitative data to enable phenotypic profiling of tumors. While radiomics has been associated with several clinical endpoints, the complex relationships of radiomics, clinical factors, and tumor biology are largely unknown. To this end, we analyzed two independent cohorts of respectively 262 North American and 89 European patients with lung cancer, and consistently identified previously undescribed associations between radiomic imaging features, molecular pathways, and clinical factors...

Concurrent scalp electroencephalography (EEG) and functional near-infrared spectroscopy (fNIRS), which we refer to as EEG+fNIRS, promises greater accuracy than the individual modalities while remaining nearly as convenient as EEG. We sought to quantify the hybrid system's ability to decode mental states and compare it with its unimodal components. Approach. We recorded from healthy volunteers taking the category fluency test and applied machine learning techniques to the data. Main results...

Given that more than 30% of healthcare costs are wasted on inappropriate care, suboptimal care is increasingly connected to the quality of medical decisions. It has been argued that personal decisions are the leading cause of death, and 80% of healthcare expenditures result from physicians' decisions. Therefore, improving healthcare necessitates improving medical decisions, ie, making decisions (more) rational. Drawing on writings from The Great Rationality Debate from the fields of philosophy, economics, and psychology, we identify core ingredients of rationality commonly encountered across various theoretical models...

"Everyone's right to life shall be protected by law", states the article 2 of the European Convention of Human Rights (1950). This article guarantees the protection of life of all persons. The human embryo, however, does not seem to be under the protection of this article, or, at least not always. The human embryo does not have a nature clearly defined and it is not considered always as person. The law protects only two categories by its ordinary regulations: things and persons. Our main objective is to find out if the human embryo is or not protected, according to the legal framework in Romania...

Hypersensitivity pneumonitis (HP; extrinsic allergic alveolitis) is a rare non-immunoglobulin E (IgE)-mediated inflammatory lung disease caused by inhalation exposure (occupational, recreational or ordinary home exposure). A 36-year-old female patient, without significant medical history, is referred to an outpatient pulmonology clinic for dry cough, shortness of breath, fever, fatigue and weight loss. Chest high-resolution computed tomography (HRCT) was performed, and significant lung fibrosis (especially centrilobular and interlobular in bilateral "thick lines"), traction bronchiectasis and alveolitis in both superior lobes are described...

Chao Yu, Rui-Yun Peng
With the increasing knowledge of shortwave radiation, it is widely used in wireless communications, radar observations, industrial manufacturing, and medical treatments. Despite of the benefits from shortwave, these wide applications expose humans to the risk of shortwave electromagnetic radiation, which is alleged to cause potential damage to biological systems. This review focused on the exposure to shortwave electromagnetic radiation, considering in vitro, in vivo and epidemiological results that have provided insight into the biological effects and mechanisms of shortwave...

Nabil Amirouchene-Angelozzi, Charles Swanton, Alberto Bardelli
Recent technological advances in the field of molecular diagnostics (including blood-based tumor genotyping) allow the measurement of clonal evolution in patients with cancer, thus adding a new dimension to precision medicine: time. The translation of this new knowledge into clinical benefit implies rethinking therapeutic strategies. In essence, it means considering as a target not only individual oncogenes but also the evolving nature of human tumors. Here, we analyze the limitations of targeted therapies and propose approaches for treatment within an evolutionary framework...

Bartłomiej Włodarczyk, Jakub Pietrzak
Here, we present a hybrid approach for simulating an edge illumination X-ray phase-contrast imaging (EIXPCi) set-up using graphics processor units (GPU) with a high degree of accuracy. In this study, the applicability of pixel, mesh and non-uniform rational B-splines (NURBS) objects to carry out realistic maps of X-ray phase-contrast distribution at a human scale is accounted for by using numerical anthropomorphic phantoms and a very fast and robust simulation framework which integrates total interaction probabilities along selected X-ray paths...

BACKGROUND: Chikungunya virus (CHIKV) is transmitted via mosquito bite and potentially by aerosol, causing chikungunya fever and arthritic disease in humans. There are currently no licensed vaccines or antiviral therapeutics to protect against CHIKV infection in humans. Animal models recapitulating human disease, especially for transmission by aerosol, are needed for licensure of such medical countermeasures. METHODS: Cynomolgus macaques (CMs) were challenged by intradermal (ID) inoculation or exposure to an aerosol containing CHIKV Ross strain at different target infectious doses (10(3)-10(7) plaque forming units (PFU))...

Hepatitis E virus (HEV) infection is a major cause of acute hepatitis but also provokes chronic infection in immunocompromised patients. Although the pathogenesis and treatment outcome involve complex interplay between the virus and host, the nature of adaptive responses of HEV to the host immune system remain obscure at best. In this study, we employed large-scale proteomic bioinformatics to profile characteristic mutations in human HEV isolates associated to ribavirin treatment failure, chronic hepatitis, hepatic failure or altered immunoreactivity...

Pediatric sHKTx has become an effective therapy for patients with combined cardiac and renal failure. Often, these patients develop human leukocyte antigen antibodies from their previous allografts and are therefore more difficult to re-transplant. We describe the largest case series of a predominantly sensitized pediatric sHKTx with emphasis on medical management and patient outcomes. Demographics, clinical characteristics, antibody, and biopsy data were retrospectively collected from University of California, Los Angeles database and correlated with short- and long-term patient and allograft outcomes of all sHKTx performed between 2002 and 2015...

The plasma derived immunoglobulin G (IgG) used either for diagnostic purpose or intravenous application (in form of IVIG) in various medical therapies is certainly gaining more and more attention on annual basis. Different manufacturing processes are used to isolate immunoglobulins from human plasma. However, a quest for alternative paths in IgG isolation not only requires development of the most efficient isolation process, but also a rapid and reliable analytics to track the purification. Fast and reliable fingerprint-based method for characterization of IgG prepared from Cohn I+II+III paste is presented in this paper...

Cardiovascular disease is the leading case of mortality from non-communicable diseases (NCD) in India. The government's National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases and Stroke seeks to increase capacity building, screening, referral and management of NCDs across India, and includes community-based outreach and screening programmes. The government in India routinely provides basic care at religious mass gatherings. However, in 2015, at the Kumbh Mela in Nashik and Trimbakeshwar, the state government extended its services to include a hypertension screening programme...
