Treading on the unknown increases prefrontal activity: A pilot fNIRS study.

Background: Complex walking conditions (e.g. dual tasking) have been associated with increased prefrontal (PFC) activity.

Video examination via the smartphone: A reliable tool for shoulder function assessment using the constant score.

Background: The use of video examinations (VE) may improve patient care by offering them a low-cost and easy access to physicians, save traveling expenses and shorten waiting time. The aim of this study was to validate the use of Smartphones for distant assessment of shoulder function by comparing the Constant scores (CS) of patients obtained by both VE and conventional face-to-face (FTF) examination.

Methods: Fifty-one subjects (age 19-80 years; women:men 18:33) who presented to a shoulder clinic with a variety of complaints were prospectively recruited and underwent FTF and VE in alternating order.

Increased inhibition following negative cues: A possible role for enhanced processing.

Based on findings showing that attention is captured by aversive stimuli, previous studies have hypothesized that inhibition of return (IOR) is reduced at spatial locations previously occupied by threat cues. Yet evidence for this view is limited: Only a few studies have demonstrated a reduced degree of IOR following threat cues, while most have not found differences in IOR between aversive and neutral cues. In contrast to previous studies that used the spatial cuing paradigm and for the most part employed mild negative stimuli as cues, we examined the influence of highly aversive, colored and complex pictures of real life situations.

Early cognitive processes in OCD: An ERP study.

Background: Obsessive-compulsive disorder (OCD) is characterized by persistent, intrusive, and distressing obsessions and/or compulsions and is associated with marked impairments in quality of life. The goal of the present study was to examine initial stages of information processing, specifically, perceptual and attention orientation phases that precede response preparation in OCD.

Methods: The P3 event-related potential (ERP) component was used as a measure of early cognitive processes of visual stimulus perception.

On the form and bio-mechanics of venom-injection elements.

A wide variety of animals-from insects to snakes-crucially depend on their ability to inject venom into their target, be it their prey or their predator. To effectively deliver their venom, venomous animals use a specialized biomechanical element whose tip must penetrate through the integument of the target. During this process, the tip of the venom-injection element (VIE) is subject to local forces, which may deform it and cause considerable structural damage to the VIE, with devastating consequences for the survival of the animal or, in the case of eusocial insects, to the colony.

Space counts! Brain correlates of spatial and numerical representations in synaesthesia.

Over-learned semantic representations, such as numbers, are strongly associated with space in normal cognition, and in the phenomenon called number-space synaesthesia. In number-space synaesthesia, numbers are linked to spatial locations in an idiosyncratic way. Synaesthetes report numbers as belonging to a specific location, or feelings that a specific location is the right location for that number.

Adaptation of health systems to climate-related migration in Sub-Saharan Africa: Closing the gap.

Health systems worldwide need to be adapted to cope with growing numbers of migrants and to climate-exacerbated morbidity. Heatwaves, water stress, desertification, flooding, and sea level rise are environmental stressors that increase morbidity, mortality, and poor mental health in Sub-Saharan Africa. While most migration is intra-African, climate change is also affecting migration patterns outside the continent.

Studying PCV impact on clinical presentation of otitis media helps to understand its pathogenesis.

Background: Complex otitis media (OM) may present with intact tympanic membrane or spontaneous otorrhea. We compared dynamics of intact tympanic membrane and spontaneous otorrhea OM following 7- and 13-valent conjugated vaccines (PCV7, PCV13) implementation, since differences in dynamics may imply different underlying mechanisms.

Methods: A prospective, population-based, active surveillance.

Object complexity modulates the association between action and perception in childhood.

Vision for action and vision for perception both rely on shape representations derived within the visual system. Whether the same psychological and neural mechanisms underlie both forms of behavior remains hotly contested, and whether this arrangement is equivalent in adults and children is controversial as well. To address these outstanding questions, we used an established psychophysical heuristic, Weber's law, which, in adults, has typically been observed for perceptual judgment tasks but not for actions such as grasping.

Individual variability in female and male mice in a test-retest protocol of the forced swim test.

Background: The challenges to embody the complexity of symptoms and biological mechanism of affective disorders question the value of animal models as well as their reproducibility and validity. Validity is further hindered by large individual variability in many models. Whereas individual variability presents a challenge, it can also be used to study susceptibility and resistance.

AAPT Diagnostic Criteria for Fibromyalgia.

Fibromyalgia (FM) is a common chronic pain disorder that presents diagnostic challenges for clinicians. Several classification, diagnostic and screening criteria have been developed over the years, but there continues to be a need to develop criteria that reflect the current understanding of FM and are practical for use by clinicians and researchers. The Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION) public-private partnership with the U.

A proteomics approach for the identification of species-specific immunogenic proteins in the Mycobacterium abscessus complex.

The Mycobacterium abscessus complex can cause fatal pulmonary disease, especially in cystic fibrosis patients. Diagnosing M. abscessus complex pulmonary disease is challenging.

Classification of Solitary Plasmacytoma, Is it more Intricate than Presently Suggested? A Commentary.

A query regarding the definition and the classification of solitary plasmacytoma is apparently still pending. The clinical course, the response to treatment and the propensity to progress to plasma cell myeloma, are all a function of the classification which must be established on a firm basis. Solitary plasmacytoma should be recognized in the continuum of the plasma cell neoplasms.

The effects of repetitive presentation of specific hazards on eye movements in hazard perception training, of experienced and young-inexperienced drivers.

Recent evidence shows that compared to experienced drivers, young-inexperienced drivers are more likely to be involved in a crash mainly due to their poor hazard perception (HP) abilities. This skill develops with experience and may be developed through training. We assumed that as any other skill, HP developed through implicit learning.

Body mass index in obsessive-compulsive disorder.

Background: Psychiatric disorders are associated with overweight/obesity. Obsessive-compulsive disorder (OCD) may be an exception, as anecdotal evidence suggests lower BMI in OCD. Additionally, depression is associated with elevated BMI, but effects of comorbid secondary depression are unknown.

Soil health assessment: A critical review of current methodologies and a proposed new approach.

The wellbeing of soils is crucial for securing food production worldwide. The soil health (SH) concept has been introduced due to an evolving understanding that soil is not just a growing medium for crops but that it provides a foundation for other essential ecosystem services (ES). The SH concept requires development of a holistic index for reliable and quantitative assessment of soil wellbeing related to the effects of different soil management practices and land uses.

Existentially Oriented Group Intervention for Patients With Heart Failure: Intervention Development and Preliminary Assessment.

Background: Patients with heart failure (HF) cope with a chronic, life-threatening, particularly disabling medical condition. Their well-being is considered to be at a greater risk than that of patients with any other cardiovascular disease, and their psychological distress is associated with a worse prognosis. These patients are often preoccupied with existential concerns such as fear of death, loneliness, and a loss of sense of meaning.

Fluorescence-based kinetic analysis of miniaturized protein microarrays.

Ideal monitoring devices should enjoy a combination of characteristics, e.g. high sensitivity, multiplexing, portability, short time-to-result (TTR).

The burden of depression in systemic sclerosis patients: a nationwide population-based study.

Background: Systemic sclerosis (SSc) can clinically present with psychological symptoms, including pain, depression, and distress about disfigurement, physical and social functioning. The existing small studies have reported a prevalence of depression ranging from 36% to 65% among SSc patients, likely reflecting the disease impact on the patient's self-image and function.

Aim Of The Study: To investigate the association between SSc and depression using big data analysis methods.

An environmentally-friendly chitosan-lysozyme biocomposite for the effective removal of dyes and heavy metals from aqueous solutions.

Developing efficient and cost-effective adsorbents for removing heavy metals and dyes from water streams is of utmost importance as prolonged human and animals consumption might lead to adverse health effects. In the present study, an environmentally-friendly bio-composite of a polysaccharide with a protein was prepared, by conjugating chitosan to lysozyme using glutaraldehyde as a crosslinker. We investigated the utility of this chitosan-lysozyme biocomposite (CLC) as an adsorbent for the removal of methyl orange (MO) dye and hexavalent chromium (Cr(VI)) ions from aqueous solutions.

Effectiveness of nutritional interventions in older adults at risk of malnutrition across different health care settings: Pooled analyses of individual participant data from nine randomized controlled trials.

Background & Aims: Protein-energy malnutrition is a health concern among older adults. Improving nutritional status by increasing energy and protein intake likely benefits health. We therefore aimed to investigate effects of nutritional interventions in older adults (at risk of malnutrition) on change in energy intake and body weight, and explore if the intervention effect was modified by study or participants' characteristics, analysing pooled individual participant data.

Quantitative assessment of paraoxon adsorption to amphiphilic β-sheet peptides presenting the catalytic triad of esterases.

Organophosphate compounds that are used as pesticides affect the nervous system by binding irreversibly to the active site of the enzyme acetylcholine esterase (AChE) and disrupting neuro-signaling nerve cells. In this study we characterized adsorption of paraoxon to a set of designed peptides that present different arrangements of the three amino acids of the AChE catalytic site: histidine, glutamic-acid and serine. The peptides set included two β-strands with no net charge and three β-hairpins that differ in their net charge.

The relative invasive disease potential of Streptococcus pneumoniae among children after PCV introduction: A systematic review and meta-analysis.

Objectives: Burden of pneumococcal disease depends on the prevalence and invasive disease potential of serotypes. We aimed to estimate the invasive disease potential of serotypes in children under 5 years of age by combining data from different settings with routine immunisation with pneumococcal conjugate vaccines (PCV).

Methods: We conducted a systematic review, supplemented by unpublished data, to identify data on the frequency of pneumococcal serotypes in carriage and invasive pneumococcal disease (IPD).

Uranium and Cesium sorption to bentonite colloids under carbonate-rich environments: Implications for radionuclide transport.

In the context of geological disposal of radioactive waste, one of the controlling mechanisms for radionuclide migration through subsurface strata is sorption to mobile colloidal bentonite particles. Such particles may erode from the repository backfill or bentonite buffer and yield measurable (0.01-0.
