INTRODUCTION: Ulnar collateral ligament (UCL) reconstructions are being performed with an increasing annual incidence. The purpose of this study was to evaluate trends in UCL surgery among recently trained orthopaedic surgeons. METHODS: The American Board of Orthopaedic Surgeons (ABOS) database was used to identify all UCL reconstructions from 2004 to 2013. Procedures were identified by Current Procedural Terminology (CPT) codes and verified by International Classification of Disease, Ninth Revision (ICD-9) codes...

Nalini M Nadkarni
On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

PURPOSE: Multiband pulses are characterized by highly temporally modulated waveforms. Rapid phase or frequency modulation can be extremely demanding on the performance of radiofrequency (RF) pulse generation, which can lead to errors that can be avoided if pulses are restricted to amplitude modulation (AM) only. In this work, three existing multiband pulse design techniques are modified to produce AM waveforms. THEORY AND METHODS: Multiband refocusing pulses were designed using phase optimization, time shifting, and root flipping...

The word ''minimalism'' is a word derived from French the word ''minimum''. Whereas the lexical meaning of minimum is ''the least or the smallest quantity necessary for something'', its expression in mathematics can be described as ''the lowest step a variable number can descend, least, minimal''. Minimalism, which advocates an extreme simplicity of the artistic form, is a current in modern art and music whose origins go to 1960s and which features simplicity and objectivity. Although art, science and philosophy are different disciplines, they support each other from time to time, sometimes they intertwine and sometimes they copy each other...

CONTEXT: Interest is growing in the use of qualitative data for assessment. Written comments on residents' in-training evaluation reports (ITERs) can be reliably rank-ordered by faculty attendings, who are adept at interpreting these narratives. However, if residents do not interpret assessment comments in the same way, a valuable educational opportunity may be lost. OBJECTIVES: Our purpose was to explore residents' interpretations of written assessment comments using mixed methods...

Bitterness reduction, especially of foods and beverages containing phytonutrients, is one of the biggest challenges in the food industry because bitterness has a deleterious effect on the taste profile of foods and beverages. Neem (Azadirachta indica A. Juss) is a medicinal tree, indigenous to the Indian-subcontinent, whose medicinal properties have led to it being heralded as the tree which is the "panacea for all diseases". However, neem leaf is extremely bitter, in large part due to its limonoid content, making it unpalatable...

PURPOSE: MRI of cortical bone has the potential to offer new information about fracture risk. Current methods are typically performed with 3D acquisitions, which suffer from long scan times and are generally limited to extremities. This work proposes using 2D UTE with half pulses for quantitatively mapping bound and pore water in cortical bone. METHODS: Half-pulse 2D UTE methods were implemented on a 3T Philips Achieva scanner using an optimized slice-select gradient waveform, with preparation pulses to selectively image bound or pore water...

Traumatized muscle, such as that debrided from blast injury sites, is considered a promising and convenient tissue source for multipotent progenitor cells (MPCs), a population of adult mesenchymal stem cell (MSC)-like cells. The present study aimed to assess the regenerative therapeutic potential of human traumatized muscle-derived MPCs, e.g., for injury repair in the blast-traumatized extremity, by comparing their pro-angiogenic potential in vitro and capillary recruitment activity in vivo to those of MSCs isolated from human bone marrow, a widely-used tissue source...

Artificial cells have attracted much attention as substitutes for natural cells. There are many different forms of artificial cells with many different definitions. They can be integral biological cell imitators with cell-like structures and exhibit some of the key characteristics of living cells. Alternatively, they can be engineered materials that only mimic some of the properties of cells, such as surface characteristics, shapes, morphology, or a few specific functions. These artificial cells can have applications in many fields from medicine to environment, and may be useful in constructing the theory of the origin of life...

BACKGROUND: Influenza viruses are among the major causes of serious human respiratory tract infection worldwide. In line with the high disease burden attributable to influenza, these viruses play an important, but often neglected, role in travel medicine. Guidelines and recommendations regarding prevention and management of influenza in travellers are scarce. Of special interest for travel medicine are risk populations and also circumstances that facilitate influenza virus transmission and spread, like travel by airplane or cruise ship and mass gatherings...

To upkeep health of astronauts in a unique, isolated, and extreme environment of space is the primary goal for a successful space mission, hence, safe and efficacious medications are essential for the wellness of astronauts. Space medication has been challenged with problems related to efficacy. Along with altered physiology, one of the possible reasons could be instability of space medications in the presence of harsh spaceflight environmental conditions. Altered physical and chemical stability can result in reduced potency which can result in reduced efficacy...

INTRODUCTION: Necrotizing fasciitis (NF) is a rare, potentially fatal, infective complication that can occur after surgery. Diagnosis is still difficult and mainly based on clinical data. Only a prompt pharmacological and surgical therapy can avoid dramatic consequences. There are few reports regarding NF as a complication after aesthetic surgical procedures, and a systematic review still lacks. MATERIALS AND METHODS: We have performed a systematic review of English literature on PubMed, covering a period of 30 years...

Skin cancer is extremely common, and melanoma causes about 80% of skin cancer deaths. In fact, melanoma kills over 50 thousand people around the world each year, and these numbers are rising. Clearly, standard treatments are not effectively treating melanoma, and alternative therapies are needed to address this problem. Hibiscus tea has been noted to have medicinal properties, including anticancer effects. Extracts from Hibiscus have been shown to inhibit the growth of a variety of cancer cells. In particular, recent studies found that polyphenols extracted from Hibiscus sabdariffa by organic solvents can inhibit melanoma cell growth...

Falls and fall-related injuries are common in older populations and have negative effects on quality of life and independence. Falling is also associated with increased morbidity, mortality, nursing home admission, and medical costs. Korea has experienced an extreme demographic shift with its population aging at the fastest pace among developed countries, so it is important to assess fall risks and develop interventions for high-risk populations. Guidelines for the prevention of falls were first developed by the Korean Association of Internal Medicine and the Korean Geriatrics Society...

The cardiac impact of psychological stress historically and socially understood as boundary experiences of human life has long since become an icon. From the aching heart to the sudden death provoked by awe, horror, grief, anger, and humiliation on one side and extreme enchantment, enthusiasm, and excitement on the other, the broken heart has become a globally recognized and powerful metaphor present from folklore to popular culture to high literature and back to everyday communication. In medicine, the "broken heart syndrome" is described as a relatively new nosological entity that has been used synonymously with the term tako-tsubo or stress cardiomyopathy...

Heavy combined lung weight at autopsy is a non-specific autopsy finding associated with certain causes of death such as intoxication. There is however no clear definition of what constitutes "heavy" lung weight. Different reference values have been suggested but previous studies have been limited by small select populations and only univariate regression has been attempted. The aim of this study was to create a model to estimate lung weight from decedent parameters. We identified all cases >18 years age autopsied at the Swedish National Board of Forensic Medicine from 2000 through 2013, excluding cases with a post-mortem interval >5 days as well as cases with extreme values, totalling 24,056 cases...

The academic discipline of social medicine has always had a political and policy advocacy component, in addition to its core functions of research and teaching. Its origins lie in the 18th and 19th centuries, in the work of Johann Peter Frank and Rudolph Virchow, among others. Virchow's dictum that "politics is nothing else but medicine on a large scale" highlights that most social determinants of health are politically determined and shape population health. Yet despite intense epidemiological and sociological research on the social determinants of health, less attention has been paid to this political and policy dimension...
