#1
Jaime A Teixeira da Silva
The Paolo Macchiarini case has several ethical ramifications. Professor Macchiarini, formerly of the Karolinska Institutet (KI), became famous for the tracheal surgeries he conducted between 2008 and 2014. His rapid rise to fame was followed by an almost equally rapid fall from grace as official reports, articles in newspapers and television programmes revealed several aspects related to misconduct in his curriculum vitae, professional practices and publishing-related activity. Formal misconduct reports issued by four KI co-workers in late 2014, then again in 2016, coupled with social scandals, including the tricking of a famous US television newscaster into a false marriage, a previous arrest in Italy for apparent bribery, and acute narcissism, all tainted Macchiarini's legend...

The chemical space explored in drug discovery programs is restricted by a narrow reaction toolkit and the frequent failure of even these reactions with polar and functionalized substrates. Recently, high-throughput reaction optimization has been integrated into discovery workflows, thereby increasing the value of specific reaction classes in the toolkit. It is likely that high-throughput experimentation will enable expansion of the synthetic chemistry that is widely exploited in discovery, thereby increasing innovation in medicinal chemistry...

The increasing relevance of Information and Communication Technologies (ICTs) in medical care is indisputable. This evidence makes it necessary to start studies that analyse the scope these new forms of access to information and understanding of medicine have on the professional activity of the physician, on the attitude and on the knowledge of patients or, on the doctor-patient relationship. The purpose of this study is to explore some of these aspects in a group of physicians whose clinical activity is related to one of the greatest social impact health problems which is the treatment of chronic pain...

Anna Wexler
This paper focuses on the history of a portable shock-producing electrotherapeutic device known as the medical battery (1870-1920), which provided both direct and alternating current and was thought to cure a wide variety of ailments. The product occupied a unique space at the nexus of medicine, consumerism and quackery: it was simultaneously considered a legitimate device by medical professionals who practiced electrotherapeutics, yet identical versions were sold directly to consumers, often via newspaper advertisements and with cure-all marketing language...

Antiviral agents are increasingly considered an option for veterinary medicine. An understanding of their mechanism of activity is important to plan their administration either as monotherapy or in combination with other agents. Previous studies have shown that the broad spectrum antiviral agent favipiravir (T-705) and its derivatives T-1105 and T-1106 are efficient inhibitors of foot-and-mouth disease virus (FMDV) replication in cell culture and in vivo. However, no mechanism for their activity against FMDV has been proposed...

PURPOSE: To accelerate high-resolution diffusion imaging, rotating single-shot acquisition (RoSA) with composite reconstruction is proposed. Acceleration was achieved by acquiring only one rotating single-shot blade per diffusion direction, and high-resolution diffusion-weighted (DW) images were reconstructed by using similarities of neighboring DW images. A parallel imaging technique was implemented in RoSA to further improve the image quality and acquisition speed. RoSA performance was evaluated by simulation and human experiments...

How are health inequalities articulated across urban and rural spaces in Tanzania? This research paper explores the variations, differences, and inequalities, in Tanzania's health outcomes-to question both the idea of an urban advantage in health and the extent of urban-rural inequalities in health. The three research objectives aim to understand: what are the health differences (morbidity and mortality) between Tanzania's urban and rural areas; how are health inequalities articulated within Tanzania's urban and rural areas; and how are health inequalities articulated across age groups for rural-urban Tanzania? By analyzing four national datasets of Tanzania (National Census, Household Budget Survey, Demographic Health Survey, and Health Demographic Surveillance System), this paper reflects on the outcomes of key health indicators across these spaces...

Radiotherapy is a cornerstone of cancer therapy. The recently established particle therapy with raster-scanning protons and carbon ions landmarks a new era in the field of high-precision cancer medicine. However, molecular mechanisms governing radiation induced intracellular signaling remain elusive. Here, we present the first comprehensive proteomic and phosphoproteomic study applying stable isotope labeling by amino acids in cell culture (SILAC) in combination with high-resolution mass spectrometry to decipher cellular response to irradiation with X-rays, protons and carbon ions...

Adipose-derived mesenchymal stem cells (AMSCs) offer potential as a therapeutic option for clinical applications in musculoskeletal regenerative medicine because of their immunomodulatory functions and capacity for trilineage differentiation. In preparation for a phase I clinical trial using AMSCs to treat patients with osteoarthritis, we carried out preclinical studies to assess the safety of human AMSCs within the intra-articular joint space. Culture-expanded human AMSCs grown in human platelet-lysate were delivered via intra-articular injections into normal healthy rabbit knees and knees at risk for the development of osteoarthritis after bilateral medial anterior hemimeniscectomy...

The purpose of this study was to survey current departmental policies on treatment couch overrides and the values of table tolerances used clinically. A 25-question electronic survey on couch overrides and tolerances was sent to full members of the American Association of Physicists in Medicine (AAPM). The first part of the survey asked participants if table overrides were allowed at their institution, who was allowed to perform these overrides, and if imaging was required with overrides. The second part of the survey asked individuals to provide table tolerance data for the following treatment sites: brain/head and neck (H&N), lung, breast, abdomen/pelvis and prostate...

Cost-effective therapies to address the growing epidemic of obesity are a leading priority in modern medicine. Intragastric balloons (IGBs) are one such option, with increased effectiveness compared with pharmacotherapy and lifestyle and a lower rate of adverse events than bariatric surgery. IGBs are endoscopically placed or swallowed space-occupying devices in the stomach. Three IGB systems were approved in 2015 to 2016 by the Food and Drug Administration for use in the United States, with more devices nearing approval...

INTRODUCTION: Osteopetrosis is a connective tissue disorder resulting from abnormally dense bone predisposing patients to fracture. The clinical pattern of fractures across time and space as well as suggestive radiographic findings usually raises diagnostic suspicion. Multiple genetic mutations resulting in dysfunctional osteoclasts have been implicated in the pathogenesis of osteopetrosis with variable inheritance patterns. In severe cases, usually inherited in an autosomal recessive pattern, the medullary cavity important in the production of normal blood cell progenitors is replaced by defective endochondral bone, leading to pancytopenia and consequential extramedullary hematopoiesis...

BACKGROUND: Breast augmentation is among the most frequently performed cosmetic plastic surgeries. Providing patients with "realistic" 3D simulations of breast augmentation outcomes is becoming increasingly common. Until recently, such programs were costly and required significant equipment, training, and office space. New simple user-friendly cloud-based programs have been developed, but to date there remains a paucity of objective evidence comparing these 3D simulations with the post-operative outcomes...

BACKGROUND: The management of articular cartilage defects presents many clinical challenges due to its avascular, aneural and alymphatic nature. Bone marrow stimulation techniques, such as microfracture, are the most frequently used method in clinical practice however the resulting mixed fibrocartilage tissue which is inferior to native hyaline cartilage. Other methods have shown promise but are far from perfect. There is an unmet need and growing interest in regenerative medicine and tissue engineering to improve the outcome for patients requiring cartilage repair...

Type 2 diabetes mellitus (T2DM) has been a great burden to the world and it's urgent to develop new treatment strategies. Many targets are currently available to aid in the drug discovery of this disease as our understanding of the pathophysiology of T2DM develops. This article is intended to provide a broad ranging overview of 14 prominent molecule targets currently being pursued for the treatment of diabetes, with regard to their therapeutic rationale, small molecule modulators and application prospects. These targets are roughly divided into four general areas that correlate with insulin secretion, act on the insulin sensitivity, and have an effect on the complications...
