The effect of hyperbaric oxygen and blood platelet injection therapy on the healing of hamstring injuries in rugby players : a case series report

There are a number of ultra-structural and immuno-histochemical studies involving hyperbaric oxygen treatment in skeletal muscle, as well as soft tissue healing. Hyperbaric oxygen therapy, in conjunction with blood platelet injection therapy, serves as a valuable addition to previously known and trusted rehabilitation techniques and protocols for the healing of musculoskeletal or soft tissue injuries. The primary aim of this case report is to describe the effect on the recovery time of hamstring injuries when combining hyperbaric oxygen therapy (HBOT) and platelet rich plasma (PRP) injection therapy with exercise rehabilitation. A retrospective, post-intervention data analysis was used in this case series report. Data, obtained through collaboration with a professional rugby union and an accredited Hyperbaric Medicine (HBOT) Centre, were analysed using the Statistical Programme for the Social Sciences (SPSS) software. The significance value was set at 5%. A significant decrease in the injury time of the hamstring injuries in rugby players was noted, with a 38% reduction in injury time in players with a grade-one injury, and 45.7% reduction in players with a grade-two injury. In terms of recurrent injuries, 62% of players with grade-one injuries remained uninjured after treatment, and the percentage of re-injured players with grade-two injuries was 0% after HBOT, PRP and physical therapy treatment. The notion that the healing time of hamstring injuries will decrease when HBOT and PRP are administered in conjunction with traditional rehabilitation therapy is indicated by the data of this report.
Immunological Profiling of Paediatric Inflammatory Bowel Disease Using Unsupervised Machine Learning.

OBJECTIVES The current classification of inflammatory bowel disease (IBD) is based on clinical phenotypes, which is blind to the molecular basis of the disease. The aim of this study was to stratify a treatment naïve paediatric IBD cohort through specific innate immunity pathway profiling and application of unsupervised machine learning (UML). METHODS In order to test the molecular integrity of biological pathways implicated in IBD, innate immune responses were assessed at diagnosis in 22 paediatric patients and 10 age-matched controls. Peripheral blood mononuclear cells (PBMCs) were selectively stimulated for assessing the functionality of upstream activation receptors including NOD2, toll-like receptor (TLR) 1-2 and TLR4, and the downstream cytokine responses (IL-10, IL-1β, IL-6 & TNF-α) using multiplex assays. Cytokine data generated were subjected to hierarchical clustering to assess for patient stratification. RESULTS Combined immune responses in patients across twelve effector responses were significantly reduced compared to controls (p = 0.003) and driven primarily by 'hypofunctional' TLR responses (p values 0.045, 0.010 & 0.018 for TLR4-mediated IL-10, IL-1β & TNF-α respectively; 0.018 & 0.015 for TLR1-2 -mediated IL-10 & IL-1β). Hierarchical clustering generated three distinct clusters of patients and a fourth group of 'unclustered' individuals. No relationship was observed between the observed immune clusters and the clinical disease phenotype. CONCLUSIONS Although a clinically useful outcome was not observed through hierarchical clustering, our study provides a rationale for using an UML approach to stratify patients. The study also highlights the predominance of hypo-inflammatory innate immune responses as a key mechanism in the pathogenesis of IBD.
Effectiveness of Iodophor vs Chlorhexidine Solutions for Surgical Site Infections and Unplanned Reoperations for Patients Who Underwent Fracture Repair

Key Points Question What is the effectiveness of surgical skin preparation with iodophor solutions vs chlorhexidine solutions at reducing 90-day surgical site infections and unplanned fracture-related reoperations within 1 year of injury? Findings This trial master protocol describes 2 multicenter pragmatic cluster randomized crossover trials, Aqueous-PREP (Pragmatic Randomized Trial Evaluating Pre-Operative Aqueous and Antiseptic Skin Solution in Open Fractures) and PREPARE (Pragmatic Randomized Trial Evaluating Pre-Operative Alcohol Skin Solutions in Fractured Extremities), which seek to compare the effectiveness of iodophor and chlorhexidine surgical skin preparation solutions at reducing surgical site infections and unplanned fracture-related reoperations. Meaning Because prophylactic skin antisepsis is used prior to all surgical procedures and the application, cost, and availability of all study solutions are similar, the results are poised to inform clinical guidelines and bring about change in clinical practice.
A new look at early exposure to the flavors of the available vegetables as foundational mechanism of vegetable consumption habits and recipes of vegetables-based dishes

Abstract The flavor of the maternal diet is transferred to women’s amniotic fluid and breast milk, so that the amniotic fluid and breast milk become natural transmitters of flavor-related information developing babies are exposed to at early stages of development. We aimed to review the available evidence regarding the impact of early exposure to flavor on child vegetable intake, and to discuss for the first time possible effects of availability or unavailability of particular vegetables because of geographic reasons on these exposures, a variable that has been forgotten in the literature. We have focused on studies that have examined the association of prenatal and early postnatal -at breastfeeding- exposures to vegetable-related flavors with vegetable consumption in children. We have identified that this particular kind of exposures may lead to increases in children’s acceptance, liking of and preference for the vegetables. Especially novel has been to identify that these effects might be modulated not only by the particular flavor of the vegetable -bitter vs. sweet- and the time of exposure -prenatal vs. breastfeeding- but also by vegetable availability because of geographic reasons of the place of residence of the mother, a variable that should be taken into account in future research. This would give rise to a new research line aimed at solving the mentioned gap. Finally, a theoretical model of cyclical processes that might explain the origin and perpetuation of transmission of particular patterns of vegetable consumption and vegetables-composed dishes over time in a given population is also included here as another new contribution.
Lesion-Based Convolutional Neural Network in Diagnosis of Early Gastric Cancer

Diagnosis and evaluation of early gastric cancer (EGC) using endoscopic images is significantly important; however, it has some limitations. In several studies, the application of convolutional neural network (CNN) greatly enhanced the effectiveness of endoscopy. To maximize clinical usefulness, it is important to determine the optimal method of applying CNN for each organ and disease. Lesion-based CNN is a type of deep learning model designed to learn the entire lesion from endoscopic images. This review describes the application of lesion-based CNN technology in diagnosis of EGC.
Patterns of Cardiovascular Risk Factors in Old Age and Survival and Health Status at 90.

BACKGROUND The population age 90 years and older is the fastest growing segment of the U.S. population. Only recently is it possible to study the factors that portend survival to this age. METHODS Among participants of the Cardiovascular Health Study, we studied the association of repeated measures of cardiovascular risk factors measured over 15-23 years of follow-up and not only survival to 90 years of age, but also healthy aging outcomes among the population who reached age 90. We included participants aged 67-75 years at baseline (n = 3,613/5,888) to control for birth cohort effects, and followed participants until death or age 90 (median follow-up = 14.7 years). RESULTS Higher systolic blood pressure was associated with a lower likelihood of survival to age 90, although this association was attenuated at older ages (p-value for interaction <.001) and crossed the null for measurements taken in participants' 80's. Higher levels of high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and body mass index (BMI) were associated with greater longevity. Among the survivors to age 90, those with worse cardiovascular profile (high blood pressure, LDL cholesterol, glucose, and BMI; low HDL cholesterol) had lower likelihood of remaining free of cardiovascular disease, cognitive impairment, and disability. CONCLUSION In summary, we observed paradoxical associations between some cardiovascular risk factors and survival to old age; whereas, among those who survive to very old age, these risk factors were associated with higher risk of adverse health outcomes.
Development of Probiotic Formulations for Oral Candidiasis Prevention: Gellan Gum as a Carrier To Deliver Lactobacillus paracasei 28.4

Probiotics might provide an alternative approach for the control of oral candidiasis. However, studies on the antifungal activity of probiotics in the oral cavity are based on the consumption of yogurt or other dietary products, and it is necessary to use appropriate biomaterials and specific strains to obtain probiotic formulations targeted for local oral administration. In this study, we impregnated gellan gum, a natural biopolymer used as a food additive, with a probiotic and investigated its antifungal activity against Candida albicans. ABSTRACT Probiotics might provide an alternative approach for the control of oral candidiasis. However, studies on the antifungal activity of probiotics in the oral cavity are based on the consumption of yogurt or other dietary products, and it is necessary to use appropriate biomaterials and specific strains to obtain probiotic formulations targeted for local oral administration. In this study, we impregnated gellan gum, a natural biopolymer used as a food additive, with a probiotic and investigated its antifungal activity against Candida albicans. Lactobacillus paracasei 28.4, a strain recently isolated from the oral cavity of a caries-free individual, was incorporated in several concentrations of gellan gum (0.6% to 1% [wt/vol]). All tested concentrations could incorporate L. paracasei cells while maintaining bacterial viability. Probiotic-gellan gum formulations were stable for 7 days when stored at room temperature or 4°C. Long-term storage of bacterium-impregnated gellan gum was achieved when L. paracasei 28.4 was lyophilized. The probiotic-gellan gum formulations provided a release of L. paracasei cells over 24 h that was sufficient to inhibit the growth of C. albicans, with effects dependent on the cell concentrations incorporated into gellan gum. The probiotic-gellan gum formulations also had inhibitory activity against Candida sp. biofilms by reducing the number of Candida sp. cells (P < 0.0001), decreasing the total biomass (P = 0.0003), and impairing hyphae formation (P = 0.0002), compared to the control group which received no treatment. Interestingly, a probiotic formulation of 1% (wt/vol) gellan gum provided an oral colonization of L. paracasei in mice with approximately 6 log CFU/ml after 10 days. This formulation inhibited C. albicans growth (P < 0.0001), prevented the development of candidiasis lesions (P = 0.0013), and suppressed inflammation (P = 0.0006) compared to the mice not treated in the microscopic analysis of the tongue dorsum. These results indicate that gellan gum is a promising biomaterial and can be used as a carrier system to promote oral colonization for probiotics that prevent oral candidiasis.
Computerized cognitive training using virtual reality on everyday life activities for patients recovering from stroke

Abstract Purpose Recent studies argue that the use of virtual reality tasks depicting activities daily living may be effective means for cognitive rehabilitation. The aim of this study was to test an ecologically oriented approach in virtual reality resembling the demands of everyday life activities for cognitive rehabilitation following stroke. Materials and Methods The sample comprised 30 sub-acute stroke patients recovering from stroke in a rehabilitation hospital. They were assessed in a single-arm pre-post intervention study on global cognition, executive functions, memory and attention abilities. The intervention consisted of virtual reality in a multidomain cognitive training approach depicting everyday life tasks (preparing food, choosing clothes, shopping, etc.). Results Improvements were found in the assessed cognitive domains at 6 to 10 post-treatment sessions. In-depth analysis through reliable change scores has suggested larger treatment effects on global cognition. Conclusions Overall results suggest that the use of virtual reality-based exercises on everyday life activities may be a useful cognitive rehabilitation approach to provide short-term gains in cognition following stroke. Implications for rehabilitation Virtual reality-based cognitive rehabilitation resembling everyday life activities may provide short-term gains in cognition of stroke patients; Consistent improvements in executive functions may require higher treatment dosage than for improvements in global cognition.
Effects of Bilberry Supplementation on Metabolic and Cardiovascular Disease Risk

Metabolic syndrome is a cluster of interrelated conditions that is associated with an increased risk of cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). Oxidative stress may impair normal physiological functions, leading to various illnesses. T2DM is considered to be associated with increased oxidative stress, inflammation, and dyslipidemia, which may play a significant role in the development of cardiovascular complications, cancer and vision loss through cataracts and retinopathy. While conventional therapies are a cornerstone for the management of the major risk factors of metabolic syndrome, increasing antioxidant defense by increasing intake of antioxidant-rich foods may improve long term prospects in CVD, obesity and T2DM. Bilberry (Vaccinium myrtillus L.) is one of the richest natural sources of anthocyanins which give berries their red/purple/blue coloration. Anthocyanins are powerful antioxidants and are reported to play an important role in the prevention of metabolic disease and CVD as well as cancer and other conditions. This review focuses on the potential effects of bilberry supplementation on metabolic and cardiovascular risk factors. Although there is evidence to support the use of bilberry supplementation as part of a healthy diet, the potential benefits from the use of bilberry supplementation in patients with T2DM or CVD needs to be clarified in large clinical trials.
Gallic acid and omega-3 fatty acids decrease inflammatory and oxidative stress in manganese-treated rats

Evidence abounds—epidemiological and experimental—linking overexposure to manganese with hepatic and renal dysfunction. We investigated the beneficial effects of gallic acid or omega-3 fatty acids (ω-3-FA) on hepatorenal function in rats exposed to manganese (Mn). Rats were exposed to manganese (15 mg/kg) only or in the presence of ω-3-FA (30 mg/kg) or gallic acid (20 mg/kg) continuously for 14 days. Gallic acid or ω-3-FA co-treatment significantly (P < 0.05) suppressed manganese-mediated increases in the biomarkers of hepatorenal toxicity. Furthermore, gallic acid or ω-3-FA relieved manganese-induced oxidative stress, lipid peroxidation, and glutathione depletion.In addition to decreases in nitric oxide, interleukin-1β, tumor necrosis factor-α levels, and myeloperoxidase concentration in treated rats, biochemical data on hepatorenal protection were buttressed by our histological findings. Gallic acid or ω-3-FA ameliorated manganese-induced hepatorenal toxicity by reducing the oxidative/inflammatory stress and preserved tissue integrity in rats. Impact statement Humans and animals are regularly exposed to toxic chemicals with subsequent adverse effects. Manganese exposure occurs via contaminated sources; over-exposure is associated with neuronal, hepatorenal dysfunction, etc. This work advances the field of natural chemopreventive agents by reporting evidence lacking in the literature on GA and ω-3-FA obtained primarily from the diet in protecting biological beings against toxic chemicals. Individually, GA and ω-3-FA exhibit various pharmacological effects. Our findings confirm the previous reports; however, we demonstrate the additional evidence for GA and ω-3-FA in abating toxic response incumbent on oxidative damage associated with manganese exposure. These findings further underscore the relevance of GA usage in food, cosmetics–pharmaceutical industries, and ω-3-FA as a safe supplement. Dietary supplements with GA and fish oil-rich in ω-3FA may be the potential natural therapy against hepatorenal injury in individuals inadvertently or occupationally exposed to manganese, thereby, promoting human and veterinary health outcomes.
Synthetic Ruthenium Complex TQ-6 Potently Recovers Cerebral Ischemic Stroke: Attenuation of Microglia and Platelet Activation

Activated microglia are crucial in the regulation of neuronal homeostasis and neuroinflammation. They also contribute to neuropathological processes after ischemic stroke. Thus, finding new approaches for reducing neuroinflammation has gained considerable attention. The metal ruthenium has gained notable attention because of its ability to form new complexes that can be used in disease treatment. [Ru(η6-cymene)2-(1H-benzoimidazol-2-yl)-quinoline Cl]BF4 (TQ-6), a potent ruthenium (II)-derived compound, was used in this study to investigate its neuroprotective action against microglia activation, middle cerebral artery occlusion (MCAO)-induced embolic stroke, and platelet activation, respectively. TQ-6 (2 μM) potently diminished inflammatory mediators (nitric oxide/inducible nitric oxide synthase (iNOS) and cyclooxygenase 2 (COX-2)) expression, nuclear factor kappa B (NF-κB) p65 phosphorylation, nuclear translocation, and hydroxyl radical (OH•) formation in LPS-stimulated microglia. Conversely, TQ-6 increased the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1). Moreover, it significantly reduced brain infarct volume and edema in MCAO mice. Additionally, it drastically inhibited platelet aggregation and OH• production in mice platelets. This study confirmed that TQ-6 exerts an anti-neuroinflammatory effect on microglia activation through neuroprotection, antiplatelet activation, and free radical scavenging. The authors propose that TQ-6 might mitigate neurodegenerative pathology by inhibiting the NF-κB-mediated downstream pathway (iNOS and COX-2) and enhancing Nrf2/HO-1 signaling molecules in microglia.
Self-Avoiding Random Walks as a Model to Study Athermal Linear Polymers under Extreme Plate Confinement

Monte Carlo (MC) simulations, built around chain-connectivity-altering moves and a wall-displacement algorithm, allow us to simulate freely-jointed chains of tangent hard spheres of uniform size under extreme confinement. The latter is realized through the presence of two impenetrable, flat, and parallel plates. Extreme conditions correspond to the case where the distance between the plates approaches the monomer size. An analysis of the local structure, based on the characteristic crystallographic element (CCE) norm, detects crystal nucleation and growth at packing densities well below the ones observed in bulk analogs. In a second step, we map the confined polymer chains into self-avoiding random walks (SAWs) on restricted lattices. We study all realizations of the cubic crystal system: simple, body centered, and face centered cubic crystals. For a given chain size (SAW length), lattice type, origin of SAW, and level of confinement, we enumerate all possible SAWs (equivalently all chain conformations) and calculate the size distribution. Results for intermediate SAW lengths are used to predict the behavior of long, fully entangled chains through growth formulas. The SAW analysis will allow us to determine the corresponding configurational entropy, as it is the driving force for the observed phase transition and the determining factor for the thermodynamic stability of the corresponding crystal morphologies.
Omission of Heart Transplant Recipients From the Appropriate Use Criteria for Revascularization and the Ramifications on Heart Transplant Centers.

Importance Guidelines endorse routine coronary angiography and percutaneous coronary intervention (PCI) to screen for and treat cardiac allograft vasculopathy in heart transplant recipients. However, the current Appropriate Use Criteria for Revascularization (AUC-R) do not recognize prior heart transplant as a unique PCI indication. Whether this affects rates of rarely appropriate (RA) PCIs is unknown. Objective To assess the rate of RA PCI procedures in heart transplant recipients and how it pertains to hospital PCI appropriateness metrics and pay-for-performance scorecards. Design, Setting, and Participants This observational study used National Cardiovascular Data Registry CathPCI Registry data on all patients undergoing elective PCIs from 96 Medicare-approved heart transplant centers from quarter 3 of 2009 to quarter 2 of 2017. The data were analyzed in July 2018. Exposures Prior heart transplant. Main Outcomes and Measures Rates of RA elective PCIs in heart transplant recipients compared with nonrecipients and hospital rates of RA PCI before vs after exclusion of heart transplant recipients using paired t tests. In a subset of heart transplant centers participating in the Anthem Blue Cross and Blue Shield's Quality-In-Sights Hospital Incentive Program (Q-HIP), we compared the change in Q-HIP scorecards before vs after excluding heart transplant recipients. Results Of 168 802 participants, 123 124 (72.9%) were men, 137 457 were white, and the mean (SD) age was 66.3 (11.4) years. Of 168 802 elective PCIs performed in heart transplant centers, 1854 (1.1%) were for heart transplant recipients. Heart transplant recipients were less likely to have ischemic symptoms (14.6% vs 61.4%, P < .001), had lower rates of antecedent stress testing (15.0% vs 58.4%, P < .001), and had higher RA PCI rates (66.0% vs 16.9%, P < .001) compared with nonrecipients. In heart transplant centers, the absolute difference in RA rates (before vs after excluding transplant recipients) was directly associated with the proportion of PCIs performed in heart transplant recipients (r = 0.91; P < .001). In the subset of heart transplant centers participating in Q-HIP during the 2016 and 2017 calendar years, 8 of 20 (40%) and 8 of 16 centers (50%), respectively, could have benefited from a change in their Q-HIP scorecards if their RA PCI rates excluded transplant recipients. Conclusions and Relevance Two-thirds of PCIs in heart transplant recipients were deemed RA by the AUC-R. The failure of the AUC-R to consider prior heart transplant as a unique PCI indication may lead to inflated RA PCI rates with the potential for affecting quality reporting and pay-for-performance metrics in heart transplant centers.
