D-chiro-inositol prevents memory deficits in the 3xTg mouse model of Alzheimerâs disease in a sex-dependent manner.
Subida por la tutora, a peticiĂłn de Beatriz Pacheco SĂĄnchez.Alzheimerâs disease (AD) is recognized as an age-related neurodegenerative disorder, characterized by the aggregation and deposition of amyloid-ÎČ (AÎČ) in plaques and neurofibrillary tangles (NFTs) composed of aggregates of hyperphosphorylated tau, a microtubule-associated protein. Sporadic AD, the most prevalent form of the disease, has been proposed to be associated with alterations on insulin signaling. Insulin regulates a series of cognitive processes, such as learning and memory formation and emerging data demonstrate pivotal roles for brain insulin resistance and insulin deficiency as mediators of neurodegeneration, particularly in AD.
The present study describes the effect of oral dietary administration of D-Chiro-inositol (DCI), an inositol used against insulin resistance, on the occurrence of the cognitive impairment of 3xTg-AD mice. This so called âtripleâ transgenic miceâ model mimics many critical aspects of AD neuropathology. To this end, we analysed the effects of daily oral administration DCI 200 mg/Kg/day in male and female 3xTg and WT mice of 9 and 3 months of age. In addition to the evaluation of memory on the Novel Object Recognition, both the locomotion and time in the centre zone of an open field (OF), and the locomotion and anxiety-like behaviour in the elevated plus maze (EPM) test, were monitored.
Our results showed that the exploration time of the new object was remarkably higher in the male 3xTg-DCI group when compared to those obtained from the 3xTg-vehicle and WT- vehicle groups at a middle and older age (3 and 9 months). When the center exploration time was analyzed in OPF test, three-way ANOVA showed an effect of the genotype in middle-aged animals. In the EPM test, only 9 months old 3xtg-DCI females were more prone to explore the open-arm, suggesting DCI decreases anxiety levels related to AD. In conclusion, our study suggest that DCI prevents and improves in a sex-dependent manner, the cognitive impairment associated to AD.Universidad de MĂĄlaga.

Biloma secondary to blunt liver trauma in a pediatric patient: case report
Liver is the organ most frequently injured after blunt or penetrating abdominal trauma, being in pediatrics a pathology that has an increasing incidence; Non-operative management is the hallmark of treatment, however cases of secondary biliary leakage have been described, which may affect the intrahepatic or extrahepatic track. A male 8 years old, with blunt trauma in the right hypochondrium, presenting acute abdomen and hemodynamic instability, requiring exploratory laparotomy with a grade III liver injury in VI and VII hepatic segments. Four weeks after discharge, he presented as a complication a giant biloma in VII and VIII hepatic segments, performing percutaneous drainage guided by ultrasound. The incidence of biliary complications related to hepatic trauma is low, 4% in pediatric patients, dividing into bilomas or biliary fistulas; the presentation of biliary leakage is very non-specific and early diagnosis difficult; in the bilomas, the tomography allows to define precisely its size, nature, distribution and regional anatomy in relation to adjacent structures, as well as underlying cause. The approach of choice is percutaneous or endoscopic drainage, with surgical management being the last option
Is skin grafting in the patient with cutaneous sporotrichosis the definitive therapy?
Sporotrichosis is a subacute to chronic infection caused by the dimorphic fungal genus Sporothrix. The infection usually affects the skin and subcutaneous tissues, but occasionally it can occur at other sites, mainly in immunocompromised patients. The symptoms of extracutaneous sporotrichosis can be subtle and diagnosis is often delayed. A 54-year-old male was received, originally from Huajuapan de León, Oaxaca; who was with an established diagnosis of type 2 diabetes mellitus; later admitted by the general surgery service with a diagnosis of necrotizing fasciitis of the left and right thoracic limb. When culture was collected with Sporothrix schenckii report, management was established with itraconazole, potassium iodide and with subsequent addition of amphotericin B, with antibiotic therapy directed for superinfection by opportunistic agents. After multiple surgical cleanings with degradation of necrotic tissue, implementation of negative pressure system and amputation of nonviable fingers, it was decided to proceed with the application of skin autografts, despite the persistence of the agent in subsequent culture reports, which are fully integrated, without evidence of new ulcerodular lesions so far. Although there are currently no parameters defined in the literature that guide the time or the appropriate conditions to perform skin grafts in the areas affected by cutaneous sporotrichosis, there are, on the contrary, reports of successful cases where surgical management has been effective even in the presence of positive cultures for Sporothrix schenckii. We consider that these results open the panorama of options for the current management of cutaneous sporotrichosis, making it necessary to consider surgical management in the therapeutic range of the same, allowing the deliberation on other more conservative options before the failure of classical therapy and the imminence of amputation
Endocrine and Metabolic impact of oral ingestion of a carob-pod derived natural syrup containing D-Pinitol: potential use as a novel sweetener in diabetes
The use of added sugars or non-nutritive sweeteners in processed foods and soft drinks are being blamed for multiple complications associated with obesity and diabetes. High fructose content contributes to obesity and liver steatosis, and excessive consumption of non-nutritive sweeteners can generate gut dysbiosis complicating the metabolic control exerted by the liver. Beyond its evolutionary significance in the selection of foods with a high glucose content as an energy source, the fact is that the consumption of sweets produces a hedonic pleasure in our brain. Then, the challenge stands at: how do we control the use of added sugars while providing a safe, palatable, sweet flavour to foods?. The present work explores an alternative approach, in humans and rodents, for sweetening through the use of a simple carob-pod-derived syrup which contains the inositol D-Pinitol. This inositol is known as an insulin sensitizer in muscle capable of keeping glycaemia while avoiding both unnecessary insulin secretion and the conversion of carbohydrates into fat depots .Universidad de MĂĄlaga.

Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions
Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41â6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000â2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p < 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2â79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999â2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study
Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9â27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6â16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2â1.8), stage II (OR 1.6; 95% CI 1.4â1.9), and stage III or worse (OR 2.8; 95% CI 2.3â3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
