#1
Alexander Nissen, Fia Yi
Colonic intussusception is an uncommon phenomenon in adults. Advanced imaging has facilitated the increase in awareness of this rare disease. When present, the lead point is most often secondary to a malignancy with primary adenocarcinoma being the most frequent cause. Current surgical management involves oncologic resections for this reason. This is a report of the third ever-reported case of colonic intussusception secondary to an angiolipoma and the first in the western hemisphere. We also demonstrate that these masses are amenable to minimally invasive resection for definitive management...

BACKGROUND: While the overall smoking quit rate has increased over time, it is not known whether the quit rate has also increased among persons with alcohol use disorders (AUDs) or heavy alcohol use (HAU). The current study examined quit rates among adults with and without AUDs and HAU over a 12-year period in a representative sample of US adults. METHODS: Data were drawn from the National Household Survey on Drug Use, an annual cross-sectional study of US persons...

OBJECTIVE: To explore the relationship between indwelling urinary catheters (IUCs), urinary incontinence (UI), and death in the poststroke period and to determine when, after the neurological event, UI has the best ability to predict 1-year mortality. METHODS: In a prospective observational study, 4477 patients were followed up for 1 year after a first-ever stroke. The impact of UI or urinary catheters on time to death was adjusted in a Cox model for age, sex, Glasgow Coma Scale, prestroke and poststroke Barthel Index, swallow test, motor deficit, diabetes, and year of inclusion...

The ever-growing production of engineered nanoparticles (NPs) for use in many agricultural, commercial, consumer, and industrial applications will lead to their accidental or intentional release into the environment. Potential routes of environmental exposure include manufacturing or transport spills, disposal of NP-containing products down the drain and/or in landfills, as well as direct usage on agricultural land. Therefore, NPs will inevitably contaminate aquatic environments and interact with resident organisms...

OBJECTIVE: To identify the critical factors that determine recommendations and other decisions about health care related tests and diagnostic strategies (HCTDS). METHODS: We used a qualitative descriptive approach and conducted semi-structured in-depth interviews with 24 international experts (informants) in evidence and decisions about HCTDS. RESULTS: Although test accuracy (TA) was the factor most commonly considered by organizations when developing recommendations about HCTDS, informants agreed that TA is necessary but rarely, if ever, sufficient and may be misleading when solely considered...

BACKGROUND: Biologic therapy is effective for treatment of moderate-to-severe psoriasis but may be associated with an increased risk for serious infection. OBJECTIVE: To estimate the serious infection rate among patients with psoriasis treated with biologic as compared with nonbiologic systemic agents within a community-based health care delivery setting. METHODS: We identified 5889 adult Kaiser Permanente Northern California health plan members with psoriasis who had ever been treated with systemic therapies and calculated the incidence rates and 95% confidence intervals (CIs) for serious infections over 29,717 person-years of follow-up...

Cadaveric organ transplantation represents the definitive treatment option for end-stage disease but is restricted by the shortage of clinically-viable donor organs. This limitation has, in part, driven current research efforts for in vitro generation of transplantable tissue surrogates. Recent advances in organ reconstruction have been facilitated by the re-purposing of decellularized whole organs to serve as three-dimensional bio-scaffolds. Notably, studies in rodents indicate that such scaffolds retain native extracellular matrix components that provide appropriate biochemical, mechanical and physical stimuli for successful tissue/organ reconstruction...

Care for children as they near the end of life is difficult and very complex. More difficult still are the decisions regarding what interventions are and are not indicated during these trying times. Occasionally, families of children who are nearing the end of life disagree with the assessment of the medical team regarding these interventions. In rare cases, the medical team can be moved to enact a do not attempt resuscitation (DNAR) order against the wishes of the patient's parents. This manuscript presents one such illustrative case and discusses the ethical issues relevant to such challenging clinical scenarios...

Droplet manipulation over open surfaces allows one to perform assays with a large degree of control and high throughput, making them appealing for applications in drug screening or (bio)analysis. However, the design, manufacturing and operation of these systems comes with high technical requirements. In this study we employ a commercial, low-friction, superhydrophobic coating, Ultra-Ever Dry(®), on a 3D-printed microfluidic device. The device features individual droplet compartments, which allow the manipulation of discrete droplets (10-50 μL) actuated by gravity alone...

Walter Herzog
Skeletal muscle mechanics have been studied ever since people have shown an interest in human movement. However, our understanding of muscle contraction and muscle mechanical properties has changed fundamentally with the discovery of the sliding filament theory in 1954 and associated cross-bridge theory in 1957. Nevertheless, experimental evidence suggests that our knowledge of the mechanisms of contraction is far from complete, and muscle properties and muscle function in human movement remain largely unknown...

Herein, an effort has been made to highlight the trends of the state-of-the-art of laccase-assisted degradation of emerging contaminants at large and endocrine disruptors in particular. Since first described in the 19th century, laccase has received particular interest for inter- and multidisciplinary investigations due to its uniqueness and remarkable biotechnological applicability. There has always been a paramount concern over the widespread occurrences of various pollutant types, around the globe. Therefore, pollution free processes are gaining ground all over the world...

Background International data suggest an increase in e-cigarette use. However, there are still significant deficits in the reporting of its current prevalence. The present study reports representative data on e-cigarette use that make it possible to differentiate users both by the nicotine content of the e-cigarette liquids being used and by their smoking status. Methods and material The underlying data are taken from the National Cancer Aid Monitoring (NCAM). In its first wave, 3000 persons aged between 14 and 45 were interviewed by telephone...

As freshwater availability is crucial for securing a sustainable, lower‑carbon future, there is a critical connection between water management and climate policies. Under a rapidly changing climate, it is more important than ever to estimate the degree of future water security. This is a challenging task as it depends on many different variables: the degree of warming and its consequent effects on hydrological resources, the water demand by different sectors, and the possible ameliorations or deteriorations of the effects due to climate change adaptation and mitigation strategies...

Radiation-induced injuries to patient skin as a result of fluoroscopy guided interventional procedures are infrequently reported, often misdiagnosed and there is a need to learn lessons from every injury. Methods: This paper describes two cases of radiation induced skin injuries that are, to the best of our knowledge, the first ever reported cases from Bulgaria and possibly from Eastern Europe, and would thus have educational value. Results: The important messages from the skin injuries reported here are: lack of awareness among part of the interventional specialists about the potential for radiation induced skin injury, misdiagnosis after injury happened because of lack of awareness and knowledge among general physicians, dermatologists and surgeons who followed up cases of skin injuries; lack of system to monitor patients with relatively high exposure; important role played by the medical physicist in diagnosing the injury and overall in initiating actions; role of training and informational material displayed in interventional facilities...

Fracture non-union is a significant problem with a wide demographic and massive socioeconomic elements, as well as the clinical difficulties it presents. Conventional treatments with autograft and allograft bone grafting pose serious difficulties, thus, it is necessary to develop novel techniques with our ever increasing knowledge of bioengineering using natural materials. Papers were searched from a variety of sources, not limited to English-language studies or only published papers. Papers had to meet the definition of fracture non-union or bone defect and had to be clinical trials, using human MSCs...

BACKGROUND: Inflammatory bowel diseases (IBD), which include Crohn's disease and Ulcerative Colitis, are inflammatory autoimmune diseases which severely affect the quality of life. Till date, no long-lasting cure has been found for the disease and all the current treatment strategies are mainly focused on dampening the symptomatic inflammatory process that has certain side effects. In addition, a large number of patients remain refractory to conventional therapies. Mesenchymal stem cells (MSCs) can be looked upon as a biodrug to treat IBD owing to their immune-suppressive and regenerative capabilities...
