Background The domestic home is the preferred site for care provision for people with dementia and their families, therefore creating a dementia and caring friendly home environment is crucial. This systematic review synthesised qualitative studies to explore the role of the home environment and identify potential barriers and facilitators in home dementia care and support to inform future practice and research. Methods A systematic search in 12 databases identified international qualitative literature on perceptions and experiences of community-dwelling people with dementia, family and formal carers regarding the role of the home environment and ways to tackle daily challenges...

INTRODUCTION AND OBJECTIVES: Acute coronary syndrome (ACS) guidelines recommend the use of newer P2Y12 inhibitors (prasugrel and ticagrelor) over clopidogrel in patients with moderate-to-high ischemic risk, unless they have an increased bleeding risk. The aim of our study was to assess the GRACE risk score and the CRUSADE bleeding risk score relative to prescription of newer P2Y12 inhibitors at discharge in ACS patients. METHODS: Retrospective analysis of a multicenter ACS registry; 3515 consecutive patients were included...

Laurent Tatu, Julien Bogousslavsky
Body representation disorders continue to be mysterious and involve the anatomical substrate that underlies the mental representation of the body. These disorders sit on the boundaries of neurological and psychiatric diseases. We present the main characteristics of 3 examples of body representation disorders: phantom sensations, supernumerary phantom limb, and apotemnophilia. The dysfunction of anatomical circuits that regulate body representation can sometimes have paradoxical features. In the case of phantom sensations, the patient feels the painful subjective sensation of the existence of the lost part of the body after amputation, surgery or trauma...

Hamid I Akbarali, William L Dewey
The prevailing opioid crisis has necessitated the need to understand mechanisms leading to addiction and tolerance, the major contributors to overdose and death and to develop strategies for developing drugs for pain treatment that lack abuse liability and side-effects. Opioids are commonly used for treatment of pain and symptoms of inflammatory bowel disease. The significant effect of opioids in the gut, both acute and chronic, includes persistent constipation and paradoxically may also worsen pain symptoms...

Genetic predisposition to obesity presents a paradox: how do genetic variants with a detrimental impact on human health persist through evolutionary time? Numerous hypotheses, such as the thrifty genotype hypothesis, attempt to explain this phenomenon yet fail to provide a justification for the modern obesity epidemic. In this critical review, we appraise existing theories explaining the evolutionary origins of obesity and explore novel biological and sociocultural agents of evolutionary change to help explain the modern-day distribution of obesity-predisposing variants...

Yaneri A Ayala, Manuel S Malmierca
The inferior colliculus is a center of convergence for inhibitory and excitatory synaptic inputs that may be activated simultaneously by sound stimulation. Stimulus repetition may generate response habituation by changing the efficacy of neuron's synaptic inputs. Specialized IC neurons reduce their response to repetitive tones, but restore their firing when a different and infrequent tone occurs, a phenomenon known as stimulus specific adaptation. Here, using the microiontophoresis technique, we determined the role of GABAA-, GABAB-, and glycinergic receptors in stimulus-specific adaptation (SSA)...

Pulmonary arteriovenous malformations (PAVMs) are structurally abnormal vascular communications that provide a continuous right-to-left shunt between pulmonary arteries and veins. Their importance stems from the risks they pose (>1 in 4 patients will have a paradoxical embolic stroke, abscess or myocardial infarction while life-threatening haemorrhage affects 1 in 100 women in pregnancy), opportunities for risk prevention, surprisingly high prevalence and under-appreciation, thus representing a challenging condition for practising healthcare professionals...

Despite the rise of small renal tumour (SRMs) diagnosis and related surgeries, death rate of kidney cancer is increasing, suggesting a non-optimal management of SRMs. Active Surveillance (AS) for kidney cancer was introduced to face this paradox. However, incertitude remains on whether and when AS can replace surgery in selected patients. We performed a literature search, reviewed and discussed the evidence in favour of AS or surgery for SRMs. Histopathology and natural history of SRMs, including the percentage of benign tumours amongst SRMs, tumour growth rate, life expectancy of SRMs patients being generally older, and current results of AS series seem to support its use in selected groups...

Introduction: The escalation in the prevalence of obesity throughout the world has led to an upsurge in the number of obese surgical patients to whom perioperative care needs to be delivered. Sources of data: After determining the scope of the review, the authors used PubMed with select phrases encompassing the words in the scope. Both preclinical and clinical reports were considered. Areas of agreement: There were no controversies regarding preoperative management and the intraoperative care of the obese surgical patient...

Thioredoxins are small thiol-oxidoreductase enzymes that control cellular redox homeostasis. Paradoxically, human thioredoxin (TXN1) was first identified as the adult T cell leukemia-derived factor (ADF), a secreted protein. ADF has been implicated in a wide variety of cell-to-cell communication systems acting as a cytokine or a chemokine. TRX80 is a truncated TXN1 protein with cytokine activity. The unconventional secretion mechanism of these extracellular thioredoxins is unknown. The thioredoxin system is relying on glucose metabolism through the pentose phosphate pathway that provides reducing power in the form of NADPH, the cofactor of thioredoxin reductase (TXNRD)...

Rho guanine exchange factors (GEFs), the enzymes that stimulate Rho GTPases, are deemed as potential therapeutic targets owing to their protumorigenic functions. However, the understanding of the spectrum of their pathobiological roles in tumors is still very limited. We report here that the GEF Vav1 unexpectedly possesses tumor-suppressor functions in immature T cells. This function entails the noncatalytic nucleation of complexes between the ubiquitin ligase Cbl-b and the intracellular domain of Notch1 (ICN1) that favors ICN1 ubiquitinylation and degradation...

Introduction: Many of the patients with lymph node tuberculosis show 'Paradoxical Response" in the form of appearance of new lymph node (LN) or increase in the size of existing LN, development of new disease in other organ and worsening of the disease while on treatment. Reason behind such response in only selective patients is not clearly understood. We evaluated the pattern and predictors for paradoxical response(s) (PR) in patients with peripheral lymph node tuberculosis (TB). Materials and Methods: Study included patients aged > 6 years with peripheral lymphadenopathy of tubercular etiology attending a tertiary care hospital from Jan 2010 to Dec 2010...

PURPOSE: Oral squamous cell carcinoma (OSCC)-related deaths mainly result from invasion of the tumor cells into local cervical lymph nodes. It has been reported that progressive basement membrane loss promotes the metastatic and invasive capacities of OSCCs. Matrix metalloproteinase-9 (MMP-9) is known to play a central role in tumor progression and invasion. However, the role of MMP-9 in OSCC invasion has so far remained paradoxical and little is known about its regulation. Here, we aimed to assess MMP-9 expression regulation and its activation by glycogen synthase kinase-3β during human OSCC progression and invasion...

Most vertebrates have a duplex retina comprising two photoreceptor types, rods for dim-light (scotopic) vision and cones for bright-light (photopic) and color vision. However, deep-sea fishes are only active in dim-light conditions; hence, most species have lost their cones in favor of a simplex retina composed exclusively of rods. Although the pearlsides, Maurolicus spp., have such a pure rod retina, their behavior is at odds with this simplex visual system. Contrary to other deep-sea fishes, pearlsides are mostly active during dusk and dawn close to the surface, where light levels are intermediate (twilight or mesopic) and require the use of both rod and cone photoreceptors...

Enterococcus faecalis is a leading causative agent of catheter-associated urinary tract infection (CAUTI), the most common hospital-acquired infection. Its ability to grow and form catheter biofilm is dependent upon host fibrinogen (Fg). Examined here are how bacterial and host proteases interact with Fg and contribute to virulence. Analysis of mutants affecting the two major secreted proteases of E. faecalis OG1RF (GelE, SprE) revealed that while the loss of either had no effect on virulence in a murine CAUTI model or for formation of Fg-dependent biofilm in urine, the loss of both resulted in CAUTI attenuation and defective biofilm formation...
