Effect of Demographic and Health Dynamics on Cognitive Status in Mexico between 2001 and 2015: Evidence from the Mexican Health and Aging Study

Sources of health disparities such as educational attainment, cardiovascular risk factors, and access to health care affect cognitive impairment among older adults. To examine the extent to which these counteracting changes affect cognitive aging over time among Mexican older adults, we examine how sociodemographic factors, cardiovascular diseases, and their treatment relate to changes in cognitive function of Mexican adults aged 60 and older between 2001 and 2015. Self and proxy respondents were classified as dementia, cognitive impairment no dementia (CIND), and normal cognition. We use logistic regression models to examine the trends in dementia and CIND for men and women aged 60 years or older using pooled national samples of 6822 individuals in 2001 and 10,219 in 2015, and sociodemographic and health variables as covariates. We found higher likelihood of dementia and a lower risk of CIND in 2015 compared to 2001. These results remain after adjusting for sociodemographic factors, cardiovascular diseases, and their treatment. The improvements in educational attainment, treatment of diabetes and hypertension, and better access to health care in 2015 compared to 2001 may not have been enough to counteract the combined effects of aging, rural residence disadvantage, and higher risks of cardiovascular disease among older Mexican adults

A Prospective, Randomized, Multicenter Trial Assessing a Novel Lysine-Derived Urethane Adhesive in a Large Flap Surgical Procedure without Drains

Objective To evaluate the safety and effectiveness of a lysine-derived urethane adhesive as a noninvasive alternative to closed suction drains in a commonly performed large flap surgical procedure.MethodsOne hundred thirty subjects undergoing abdominoplasty at five centers were prospectively randomized to standard flap closure with surgical drains (Control group) or a lysine-derived urethane adhesive (Treatment group) without drains. The primary outcome measured was the number of post-operative procedures, including drain removals (as the event marking the use of a surgical drain) and needle aspirations. Secondary endpoints included total wound drainage, cumulative days of treatment, and days to drain removal. A patient questionnaire evaluating quality of life measures was also administered.ResultsSubjects in the Treatment group required significantly fewer post-operative procedures compared to the Control group (1.8±3.8 vs. 2.4±1.2 procedures; p<0.0001) and fewer cumulative days of treatment (1.6±0.4 vs. 7.3±3.3; p<0.0001). A procedure to address fluid accumulation was required for only 27.3% of the subjects in the Treatment group versus 100% of Control group, which by study design required the use of drains. The mean duration of use of indwelling surgical drains for the Control group was 6.9±3.3days. All fluid collections treated with percutaneous aspiration were resolved and there were no unanticipated adverse events.ConclusionThe results of the study support that the use of a lysine-derived urethane adhesive is a safe and effective alternative to drains in patients undergoing a common large flap surgical procedure.Level of Evidence IThis journal requires that authors assign a level of evidence to each article.

Nitrogen fixation by Trichodesmium spp.: An important source of new nitrogen to the tropical and subtropical North Atlantic Oceean

The broad distribution and often high densities of the cyanobacterium Trichodesmium spp. in oligotrophic waters imply a substantial role for this one taxon in the oceanic N cycle of the marine tropics and subtropics. New results from 154 stations on six research cruises in the North Atlantic Ocean show depth-integrated N2 fixation by Trichodesmium spp. at many stations that equalled or exceeded the estimated vertical flux of NO3− into the euphotic zone by diapycnal mixing. Areal rates are consistent with those derived from several indirect geochemical analyses. Direct measurements of N2 fixation rates by Trichodesmium are also congruent with upper water column N budgets derived from parallel determinations of stable isotope distributions, clearly showing that N2 fixation by Trichodesmium is a major source of new nitrogen in the tropical North Atlantic. We project a conservative estimate of the annual input of new N into the tropical North Atlantic of at least 1.6 × 1012 mol N by Trichodesmium N2 fixation alone. This input can account for a substantial fraction of the N2 fixation in the North Atlantic inferred by several of the geochemical approaches

Microwave-based quantum control and coherence protection of tin-vacancy spin qubits in a strain-tuned diamond membrane heterostructure

Robust spin-photon interfaces in solids are essential components in quantum networking and sensing technologies. Ideally, these interfaces combine a long-lived spin memory, coherent optical transitions, fast and high-fidelity spin manipulation, and straightforward device integration and scaling. The tin-vacancy center (SnV) in diamond is a promising spin-photon interface with desirable optical and spin properties at 1.7 K. However, the SnV spin lacks efficient microwave control and its spin coherence degrades with higher temperature. In this work, we introduce a new platform that overcomes these challenges - SnV centers in uniformly strained thin diamond membranes. The controlled generation of crystal strain introduces orbital mixing that allows microwave control of the spin state with 99.36(9) % gate fidelity and spin coherence protection beyond a millisecond. Moreover, the presence of crystal strain suppresses temperature dependent dephasing processes, leading to a considerable improvement of the coherence time up to 223(10) ${\mu}$s at 4 K, a widely accessible temperature in common cryogenic systems. Critically, the coherence of optical transitions is unaffected by the elevated temperature, exhibiting nearly lifetime-limited optical linewidths. Combined with the compatibility of diamond membranes with device integration, the demonstrated platform is an ideal spin-photon interface for future quantum technologies

The impact of psychological factors on recovery from injury: a multicentre cohort study

Purpose Unintentional injuries have a significant long-term health impact in working age adults. Depression, anxiety and post-traumatic stress disorder are common post-injury, but their impact on self-reported recovery has not been investigated in general injury populations. This study investigated the role of psychological predictors 1 month post-injury in subsequent self-reported recovery from injury in working-aged adults. Methods A multicentre cohort study was conducted of 668 unintentionally injured adults admitted to five UK hospitals followed up at 1, 2, 4 and 12 months post-injury. Logistic regression explored relationships between psychological morbidity 1 month post-injury and self-reported recovery 12 months post-injury, adjusting for health, demographic, injury and socio-legal factors. Multiple imputations were used to impute missing values. Results A total of 668 adults participated at baseline, 77% followed up at 1 month and 63% at 12 months, of whom 383 (57%) were included in the main analysis. Multiple imputation analysis included all 668 participants. Increasing levels of depression scores and increasing levels of pain at 1 month and an increasing number of nights in hospital were associated with significantly reduced odds of recovery at 12 months, adjusting for age, sex, centre, employment and deprivation. The findings were similar in the multiple imputation analysis, except that pain had borderline statistical significance. Conclusions Depression 1 month post-injury is an important predictor of recovery, but other factors, especially pain and nights spent in hospital, also predict recovery. Identifying and managing depression and providing adequate pain control are essential in clinical care post-injury

Evaluation of the Impact of the Trivedi Effect® -Energy of Consciousness on the Structure and Isotopic Abundance Ratio of Magnesium Gluconate Using LC-MS and NMR Spectroscopy

Magnesium gluconate is a classical pharmaceutical/nutraceutical compound used as a magnesium ion source for the prevention and treatment of hypomagnesemia. The present study was aimed to investigate the effect of The Trivedi Effect® - Energy of Consciousness Healing Treatment (Biofield Energy Healing Treatment) on magnesium gluconate for the change in the structural properties and isotopic abundance ratio (PM+1/PM and PM+2/PM) using LC-MS and NMR spectroscopy. Magnesium gluconate was divided into two parts – one part was control, and another part was treated with The Trivedi Effect® - Biofield Energy Healing Treatment remotely by twenty renowned Biofield Energy Healers and defined as The Trivedi Effect® Treated sample. The LC-MS analysis of both the control and treated samples indicated the presence of mass of the protonated magnesium gluconate at m/z 415 at the retention time of 1.52 min and fragmentation pattern of the both sample were almost similar. The relative peak intensities of the fragment ions were significantly changed in the treated sample compared with the control sample. The proton and carbon signals for CH, CH2 and CO groups in the proton and carbon NMR spectra were observed almost similar for the control and the treated samples. The percentage change in the isotopic abundance ratio of PM+1/PM (2H/1H or 13C/12C or 17O/16O or 25Mg/24Mg) was significantly decreased in the treated sample by 17.51% compared with the control sample. Consequently, the isotopic abundance ratio of PM+2/PM (18O/16O or 26Mg/24Mg) in the treated sample was significantly increased by 79.44% compared to the control sample. Briefly, 13C, 2H, 17O, and 25Mg contributions from (C12H23MgO14)+ to m/z 416; 18O and 26Mg contributions from (C12H23MgO14)+ to m/z 417 in treated sample were significantly altered compared with the control sample. Thus, The Trivedi Effect® Treated magnesium gluconate might be supportive to design the novel potent enzyme inhibitors using its kinetic isotope effects. Consequently, The Trivedi Effect® Treated magnesium gluconate would be valuable for designing better pharmaceutical and/or nutraceutical formulations through its changed physicochemical and thermal properties, which might be providing better therapeutic response against various diseases such as diabetes mellitus, allergy, aging, inflammatory diseases, immunological disorders, and other chronic infections.

Evaluation of the Physicochemical, Structural, Thermal, and Behavioral Properties of the Energy of Consciousness Healing Treated Zinc Chloride

Zinc chloride is a source of zinc used in various pharmaceutical/nutraceutical formulations. The objective of the current study was to investigate the impact of The Trivedi Effect® - Energy of Consciousness Healing Treatment (Biofield Energy Treatment) on physical, structural, thermal, and behavioral properties of zinc chloride using PXRD, PSD, FT-IR, UV-vis, and DSC analysis. Zinc chloride was divided into two parts – one part was control, while another part was treated with The Trivedi Effect® remotely by twenty renowned Biofield Energy Healers and defined as The Trivedi Effect® Treated sample. A significant alteration of the crystallite size and relative intensities of the PXRD peaks was observed in The Trivedi Effect® treated sample compared with the control sample. The average crystallite size of the treated sample was significantly increased by 23.18% compared with the control sample. The particle size values at d10, d50, and d90 values were significantly decreased by 3.70%, 4.13%, and 6.13%, respectively in the treated sample compared with the control sample. Therefore, the surface area of the treated sample was increased by 4.21% compared with the control sample. The FT-IR spectroscopic analysis revealed that Zn-Cl stretching in the control sample was found at 512 cm-1, whereas it was significantly shifted upward to 520 cm-1 in the treated sample. The UV-vis analysis exhibited that wavelength of the maximum absorbance (λmax) of the control and treated samples were at 197.6 nm and 197.1 nm, respectively. The DSC analysis exhibited that the melting temperature was decreased by 0.22%, while decomposition temperature was increased by 2.56% in the treated sample compared to the control sample. The latent heat of fusion of the treated sample (320.44 J/g) was significantly decreased by 16.70% compared with the control sample (284.67 J/g). Similarly, the enthalpy of decomposition of the treated sample (952.53 J/g) was significantly increased by 122.61% compared with the control sample (427.90 J/g). Thus, the results indicated that the thermal stability of the treated zinc chloride was improved compared with the control sample. The current study anticipated that The Trivedi Effect® - Energy of Consciousness Healing Treatment might lead to produce a thermally stable new polymorphic form of zinc chloride, which would be more soluble and bioavailable compared with the untreated compound. Hence, the treated zinc chloride would be very useful to design better nutraceutical/pharmaceutical formulations that might offer better therapeutic response against inflammatory diseases, immunological disorders, aging, stress, cancer, etc. https://www.trivedieffect.com/science/evaluation-of-the-physicochemical-structural-thermal-and-behavioral-properties-of-the-energy-of-consciousness-healing-treated-zinc-chloride http://www.sciencepublishinggroup.com/journal/paperinfo?journalid=217&doi=10.11648/j.bio.20170502.1

Differential Requirement for Utrophin in the Induced Pluripotent Stem Cell Correction of Muscle versus Fat in Muscular Dystrophy Mice

Duchenne muscular dystrophy (DMD) is an incurable degenerative muscle disorder. We injected WT mouse induced pluripotent stem cells (iPSCs) into mdx and mdx∶utrophin mutant blastocysts, which are predisposed to develop DMD with an increasing degree of severity (mdx <<< mdx∶utrophin). In mdx chimeras, iPSC-dystrophin was supplied to the muscle sarcolemma to effect corrections at morphological and functional levels. Dystrobrevin was observed in dystrophin-positive and, at a lesser extent, utrophin-positive areas. In the mdx∶utrophin mutant chimeras, although iPSC-dystrophin was also supplied to the muscle sarcolemma, mice still displayed poor skeletal muscle histopathology, and negligible levels of dystrobrevin in dystrophin- and utrophin-negative areas. Not only dystrophin-expressing tissues are affected by iPSCs. Mdx and mdx∶utrophin mice have reduced fat/body weight ratio, but iPSC injection normalized this parameter in both mdx and mdx∶utrophin chimeras, despite the fact that utrophin was compromised in the mdx∶utrophin chimeric fat. The results suggest that the presence of utrophin is required for the iPSC-corrections in skeletal muscle. Furthermore, the results highlight a potential (utrophin-independent) non-cell autonomous role for iPSC-dystrophin in the corrections of non-muscle tissue like fat, which is intimately related to the muscle

Psychological morbidity and health related quality of life after injury: multicentre cohort study

Purpose: To demonstrate the impact of psychological morbidity 1 month post-injury on subsequent post-injury quality of life (HRQoL) in a general injury population in the UK to inform development of trauma care and rehabilitation services. Methods: Multicentre cohort study of 16–70-year-olds admitted to 4 UK hospitals following injury. Psychological morbidity and HRQoL (EQ-5D-3L) were measured at recruitment and 1, 2, 4 and 12 months post-injury. A reduction in EQ-5D compared to retrospectively assessed pre-injury levels of at least 0.074 was taken as the minimal important difference (MID). Multilevel logistic regression explored relationships between psychological morbidity 1 month post-injury and MID in HRQoL over the 12 months after injury. Results: A total of 668 adults participated. Follow-up rates were 77% (1 month) and 63% (12 months). Substantial reductions in HRQoL were seen; 93% eported a MID at 1 month and 58% at 12 months. Problems with pain, mobility and usual activities were commonly reported at each time point. Depression and anxiety scores month post-injury were independently associated with subsequent MID in HRQoL. The relationship between depression and HRQoL was partly explained by anxiety and to a lesser extent by pain and social functioning. The relationship between anxiety and HRQoL was not explained by factors measured in our study. Conclusions: Hospitalised injuries result in substantial reductions in HRQoL up to 12 months later. Depression and anxiety early in the recovery period are independently associated with lower HRQoL. Identifying and managing these problems, ensuring adequate pain control and facilitating social functioning are key elements in improving HRQoL post-injury
