Jong Hoo Lee, Hyun Jung Kim, Yee Hyung Kim
Adding either macrolide or fluoroquinolone (FQ) to β-lactam has been recommended for patients with severe community-acquired pneumonia (CAP). However, due to the limited evidence available, there is a question as to the superiority of the two combination therapies. The MEDLINE, EMBASE, Cochrane Central Register, Scopus, and Web of Science databases were searched for systematic review and meta-analysis. A total of eight trials were analyzed. The total number of patients in the β-lactam plus macrolide (BL-M) and β-lactam plus fluoroquinolone (BL-F) groups was 2,273 and 1,600, respectively...

Borja Bandera Merchan, Sonsoles Morcillo, Gracias Martin-Nuñez, Francisco José Tinahones, Manuel Macías-González
In the last two decades vitamin D (VD) research has demonstrated new extraskeletal actions of this pre-hormone, suggesting a protective role of this secosteroid in the onset, progression and prognosis of several chronic noncommunicable diseases, such as cardiovascular disease, diabetes mellitus or cancer. Regarding carcinogenesis, both preclinical and epidemiological evidence available show oncoprotective actions of VD and its receptor, the VDR. However, in late neoplastic stages the VD system (VDS) seems to be less functional, which appears to be due to an epigenetic silencing of the system...

Briony F Hudson, Kate Flemming, Caroline Shulman, Bridget Candy
BACKGROUND: People who are homeless or vulnerably housed are a marginalized group who often experience high rates of morbidity and die young as a result of complex problems. Access to health care and support can be challenging, with access to palliative care even more so. This review presents a synthesis of published qualitative research exploring from the perspective of homeless people and those working to support them, current challenges to palliative care access and provision, in addition to suggestions for what may improve palliative care for this population...

Human immunodeficiency virus (HIV)-infected individuals successfully treated for tuberculosis (TB) remain at risk of recurrence of the disease, especially in high TB incidence settings. We performed a systematic review, investigating whether secondary preventive therapy (sPT) with anti-TB drugs (preventive therapy in former TB patients with treatment success) is an effective strategy to prevent recurrence of TB in this patient group. We searched the databases PubMed, Cochrane Library, EMBASE, Web of Science and Google Scholar using the keywords HIV-infections, HIV, human immunodeficiency virus, AIDS, isoniazid, isoniazid preventive therapy (IPT), tuberculosis, TB, recurrence and recurrent disease, resulting in 253 potential publications...

A tracer-encapsulated solid pellet (TESPEL) injection system for the TJ-II stellarator was recently developed. In order to reduce the time and cost for the development, we combined a TESPEL injector provided by National Institute for Fusion Science with an existing TJ-II cryogenic pellet injection system. Consequently, the TESPEL injection into the TJ-II plasma was successfully achieved, which was confirmed by several pellet diagnostics including a normal-incidence spectrometer for monitoring a tracer impurity behavior...

This analysis challenges a tendency in public health and the social sciences to associate India's medical pluralism with a distinction between biomedicine, as a homogeneous entity, and its non-biomedical 'others'. We argue that this overdrawn dichotomy obscures the important part played by 'informal' biomedical practice, an issue with salience well beyond India. Based on a qualitative study in rural Andhra Pradesh, South India, we focus on a figure little discussed in the academic literature - the Registered Medical Practitioner (RMP) - who occupies a niche in the medical market-place as an informal exponent of biomedical treatment...

Haber T, Kleister G, Selman B, Härtig J, Melichercik J, Ismer B
Radiofrequency (RF) ablation requires a complex set of devices as well as profound electrophysiological experience and substantial knowledge of physical science basics. To establish RF ablation in-vitro teaching-system, six workstations were equipped with computer-controlled RF ablation generators. Universal connection boxes allow ablation-essays with catheters of different make and model. Special wetlabs were developed combining a basin containing isotonic saline solution with a thermostat and a pump to simulate blood flow...

Patrick C Trettenbrein
Synaptic plasticity is widely considered to be the neurobiological basis of learning and memory by neuroscientists and researchers in adjacent fields, though diverging opinions are increasingly being recognized. From the perspective of what we might call "classical cognitive science" it has always been understood that the mind/brain is to be considered a computational-representational system. Proponents of the information-processing approach to cognitive science have long been critical of connectionist or network approaches to (neuro-)cognitive architecture, pointing to the shortcomings of the associative psychology that underlies Hebbian learning as well as to the fact that synapses are practically unfit to implement symbols...

Modern business process management (BPM) is increasingly interesting for laboratory automation. End-to-end workflow automation and improved top-level systems integration for information technology (IT) and automation systems are especially prominent objectives. With the ISO Standard Business Process Model and Notation (BPMN) 2.X, a system-independent and interdisciplinary accepted graphical process control notation is provided, allowing process analysis, while also being executable. The transfer of BPM solutions to structured laboratory automation places novel demands, for example, concerning the real-time-critical process and systems integration...

C Richard Chapman, Charles J Vierck
The nature of the transition from acute to chronic pain still eludes explanation, but chronic pain resulting from surgery provides a natural experiment that invites both clinical epidemiological investigation and basic scientific inquiry into the mechanisms of this transition. The primary purpose of this paper is to review current knowledge and hypotheses on the transition from acute to persistent postsurgical pain, summarizing literature on clinical epidemiological studies of persistent postsurgical pain development, as well as basic neurophysiological studies targeting mechanisms in the periphery, spinal cord, and brain...

During drug discovery and development the thermodynamics and kinetics of crystal form transitions must be studied and the fundamental properties of polymorphs must be identified. However, despite the accumulation of knowledge and experimental evidence that support the understanding of crystallization, its predictability still presents significant challenges. With the continuous development of new drug delivery technologies, even more complex situations arise such as difficult cases of polymorph selection, co-crystallization of different molecules, and manipulation of the crystallization environment by for example amorphous solids...

PURPOSE: Network science uses mathematical and computational techniques to examine how individual entities in a system, represented by nodes, interact, as represented by connections between nodes. This approach has been used by Cramer et al. (2010) to make "symptom networks" to examine various psychological disorders. In the present analysis we examined a network created from the items in the Overall Assessment of the Speaker's Experience of Stuttering-Adult (OASES-A), a commonly used measure for evaluating adverse impact in the lives of people who stutter...

Networks can evolve even on a short-term basis. This phenomenon is well understood by network scientists, but receive little attention in empirical literature involving real-world networks. On one hand, this is due to the deceitfully fixed topology of some networks such as many physical infrastructures, whose evolution is often deemed unlikely to occur in short term; on the other hand, the lack of data prohibits scientists from studying subjects such as social networks that seem likely to evolve on a short-term basis...

BACKGROUND: Kyphoplasty has been proven to be an efficient method to relieve patient suffering from osteoporotic vertebral compression fractures (OVCFs). Because of its technological superiority, unilateral kyphoplasty consumes less operative time and bone cement than traditional bilateral kyphoplasty. However, there is controversy about which method is most efficient in the treatment of OVCFs. Thus, an overall analysis should be performed to shed light on the facts corroborating both procedures...

Platelet-lymphocyte ratio (PLR) is a hematological parameter which is investigated as a biomarker for prognosis in patients with breast cancer. Due to the controversial results from previous studies, we performed a meta-analysis. Databases of PubMed, Embase and Web of Science were searched to identify eligible studies. STATA version 12.0 was used for statistical analysis. Seven studies with 3,741 patients were ultimately included in this meta-analysis. High PLR was associated with poor overall survival (OS) (HR = 1...

Understanding infant development is one of the great scientific challenges of contemporary science. In addressing this challenge, robots have proven useful as they allow experimenters to model the developing brain and body and understand the processes by which new patterns emerge in sensorimotor, cognitive, and social domains. Robotics also complements traditional experimental methods in psychology and neuroscience, where only a few variables can be studied at the same time. Moreover, work with robots has enabled researchers to systematically explore the role of the body in shaping the development of skill...

Of over 7,000 known rare diseases, only 5% currently have an available treatment option worldwide. Moreover, the vast majority of rare disease patients in China have no access to treatment due to limited availability and the lack of appropriate infrastructure in China's healthcare system. Despite increased interest in orphan drug development, drug companies in China with active programs on drugs to treat rare diseases are still limited. Hence, there is a huge unmet need in China, with over 10 million patients suffering from rare diseases...
