Arabidopsis Seed Mitochondria Are Bioenergetically Active Immediately upon Imbibition and Specialize via Biogenesis in Preparation for Autotrophic Growth[OPEN]

Arabidopsis seed mitochondria are bioenergetically reactivated rapidly after hydration followed by fusion-linked remodeling to form a perinuclear scaffold for membrane biogenesis. Seed germination is a vital developmental transition for production of progeny by sexual reproduction in spermatophytes. Quiescent cells in nondormant dry embryos are reawakened first by imbibition and then by perception of germination triggers. Reanimated tissues enter into a germination program requiring energy for expansion growth. However, germination requires that embryonic tissues develop to support the more energy-demanding processes of cell division and organogenesis of the new seedling. Reactivation of mitochondria to supply the required energy is thus a key process underpinning germination and seedling survival. Using live imaging, we investigated reactivation of mitochondrial bioenergetics and dynamics using Arabidopsis thaliana as a model. Bioenergetic reactivation, visualized by presence of a membrane potential, is immediate upon rehydration. However, reactivation of mitochondrial dynamics only occurs after transfer to germination conditions. Reactivation of mitochondrial bioenergetics is followed by dramatic reorganization of the chondriome (all mitochondrial in a cell, collectively) involving massive fusion and membrane biogenesis to form a perinuclear tubuloreticular structure enabling mixing of previously discrete mitochondrial DNA nucleoids. The end of germination coincides with fragmentation of the chondriome, doubling of mitochondrial number, and heterogeneous redistribution of nucleoids among the mitochondria, generating a population of mitochondria tailored to seedling growth.
The efficacy and acceptability of psychological interventions for depression: where we are now and where we are going

Depression is an eminently treatable disorder, although estimates of treatment efficacy have been inflated by publication bias. Patients with less severe depressions respond to even nonspecific interventions, whereas patients with more severe depressions require treatments that mobilize specific mechanisms. The cognitive and behavior therapies can be as efficacious as medications in the treatment of severe depression and have an enduring effect that medications lack. Medications may interfere with those enduring effects when added in combination and may prolong the life of the underlying episode when used alone. Thus the cognitive behavioral interventions might be the optimal first-line treatments for depression.
Lithium and venlafaxine poisoning — a case report

In treatment of manic-depressive conditions long-term lithium therapy may be combined with an effective and relatively safe antidepressant venlafaxine. Combined overdose may increase the risk of early toxicity of both drugs and of delayed lithium intoxication, responding to symptomatic and renal replacement therapy. We present a patient with combined lithium and venlafaxine self-poisoning with nothing but delayed signs of lithium intoxication with the emphasis on early and late treatment. 41-year old woman attempted suicide by large amount of lithium and venlafaxine. On admission she was asymptomatic, but with increased serum lithium over 5mmol/L. After gastric lavage, active charcoal and laxative administration she was receiving IV fluids. After a delay of 63 hours she deteriorated acutely by disorientation, confusion, fasciculation and tremor and was readmitted to Intensive care unit. In spite serum lithium decreased to 2mmol/L clinical signs were attributed to delayed lithium intoxication. After symptomatic and renal replacement therapy the patient’s condition improved after few days. We conclude that decontamination procedures are effective in particular for venlafaxine poisoning. If increased serum lithium levels are noted renal replacement therapy may be started even in asymptomatic patients as delayed lithium intoxication is most likely after few days.
Belatacept for renal rescue in lung transplant patients

Renal failure causes morbidity and mortality after lung transplantation and is aggravated by exposure to nephrotoxic immunosuppressant (IS) drugs. We report an off‐label experience using belatacept for lung transplant recipients with severe renal insufficiency to reduce nephrotoxic IS exposure. We analyzed data retrospectively from a consecutive series of lung transplant patients with renal insufficiency in whom belatacept treatment was initiated between June 2012 and June 2014 at the University of Maryland Medical Center. Eight patients received belatacept because of acute or chronic renal insufficiency (median) GFR 24 (IQR 18–26). Glomerular filtration rate (GFR) remained stable in two patients and increased in five. One patient with established renal and respiratory failure received only the induction dose of belatacept and died 4 months later of respiratory and multisystem organ failure. Calcineurin inhibitor or sirolimus exposure was safely withheld or reduced without moderate or severe acute rejection during ongoing belatacept in the other seven patients. FEV1 remained stable over the 6‐month study interval. Belatacept use appears to permit safe transient reduction in conventional immunosuppressive therapy and was associated with stable or improved renal function in a small retrospective series of lung transplant recipients with acute or chronic renal insufficiency.
Mycobacterium xenopi: A Case Report of a Rare Cause of Pott Disease

Abstract: Mycobacterium xenopi is classically a respiratory pathogen affecting immunocompromised hosts, which rarely causes extrapulmonary disease. We present a case of vertebral osteomyelitis and psoas abscess secondary to M. xenopi in an immunocompetent host. The case highlights the difficulties in diagnosing and treating M. xenopi infections. A literature review and treatment recommendations are presented.
Long‐term outcomes of thoracic transplant recipients following conversion to everolimus with reduced calcineurin inhibitor in a multicenter, open‐label, randomized trial

The NOCTET study randomized 282 patients ≥1 year after heart or lung transplantation to continue conventional calcineurin inhibitor (CNI) therapy or to start everolimus with reduced‐exposure CNI. Last follow‐up, at ≥5 years postrandomization (mean: 5.6 years) was attended by 72/140 everolimus patients (51.4%) and 91/142 controls (64.1%). Mean measured GFR remained stable in the everolimus group from randomization (51.3 ml/min) to last visit (51.4 ml/min) but decreased in controls (from 50.5 ml/min to 45.3 ml/min) and was significantly higher with everolimus at last follow‐up (P = 0.004). The least squares mean (SE) change from randomization was −1.5 (1.7)ml/min with everolimus versus −7.2 (1.7)ml/min for controls (difference: 5.7 [95% CI 1.7; 9.6]ml/min; P = 0.006). The difference was accounted for by heart transplant patients (difference: 6.9 [95% 2.3; 11.5]ml/min; P = 0.004). Lung transplant patients showed no between‐group difference at last follow‐up. Rates of rejection, death, and major cardiac events were similar between groups, as was graft function. Pneumonia was more frequent with everolimus (18.3% vs. 6.4%). In conclusion, introducing everolimus in maintenance heart transplant patients, with reduced CNI, achieves a significant improvement in renal function which is maintained for at least 5 years, but an early renal benefit in lung transplant patients was lost. Long‐term immunosuppressive efficacy was maintained.
Design of experiment approach for the process optimisation of microwave assisted extraction of lupeol from Ficus racemosa leaves using response surface methodology.

INTRODUCTION Triterpenoids are a group of important phytocomponents from Ficus racemosa (syn. Ficus glomerata Roxb.) that are known to possess diverse pharmacological activities and which have prompted the development of various extraction techniques and strategies for its better utilisation. OBJECTIVE To develop an effective, rapid and ecofriendly microwave-assisted extraction (MAE) strategy to optimise the extraction of a potent bioactive triterpenoid compound, lupeol, from young leaves of Ficus racemosa using response surface methodology (RSM) for industrial scale-up. MATERIAL AND METHOD Initially a Plackett-Burman design matrix was applied to identify the most significant extraction variables amongst microwave power, irradiation time, particle size, solvent:sample ratio loading, varying solvent strength and pre-leaching time on lupeol extraction. Among the six variables tested, microwave power, irradiation time and solvent-sample/loading ratio were found to have a significant effect (P < 0.05) on lupeol extraction and were fitted to a Box-Behnken-design-generated quadratic polynomial equation to predict optimal extraction conditions as well as to locate operability regions with maximum yield. RESULTS The optimal conditions were microwave power of 65.67% of 700 W, extraction time of 4.27 min and solvent-sample ratio loading of 21.33 mL/g. Confirmation trials under the optimal conditions gave an experimental yield (18.52 µg/g of dry leaves) close to the RSM predicted value of 18.71 µg/g. CONCLUSION Under the optimal conditions the mathematical model was found to be well fitted with the experimental data. The MAE was found to be a more rapid, convenient and appropriate extraction method, with a higher yield and lower solvent consumption when compared with conventional extraction techniques.
Quantitative comparison of multiple components in Dioscorea nipponica and D. panthaica by ultra-high performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.

INTRODUCTION Dioscorea nipponica (DN) and D. panthaica (DP) have been uniquely prepared as herbal medicinal products for treating coronary heart disease (CHD) in China. However, so far there has been little discussion and no work comparing the qualitative and quantitative differences between the two herbs nor assessing whether they have similarities in chemical composition that would support their common application for treating CHD. OBJECTIVE To develop an efficient and reliable method based on UPLC-qTOF-MS for quantitative comparison of saponins in both DN and DP. METHODS Using electrospray ionisation and atmospheric-pressure chemical ionisation respectively, six steroidal glycosides and one aglycone were determined in 13 DN samples and 13 DP samples. The comparative analysis of chemical components in DN and DP was carried out by chromatographic fingerprint similarity evaluation, test of significance (t-test) and principle component analysis (PCA). RESULTS The UPLC-qTOF-MS method showed limit of detection and quantitation within the range 0.02-0.2 ng and 0.08-0.5 ng, respectively, for the seven saponins studied. The intra- and interday precision (RSD) were below 5%. The recoveries for the quantified compounds were within the range of 72.79-118.31%. CONCLUSION This UPLC-qTOF-MS assay provides a suitable method for the identification and determination of major bioactive constituents both in DN and DP. The chemical composition of all DN and DP samples studied exhibited a high level of global similarity. This chemical similarity validates their common application in the pharmaceutical industry as anti-CHD herbal drugs.
An evaluation of communication barriers and facilitators at the time of a mental health diagnosis: a survey of health professional practices

Aims. To examine health professionals’ views and practices relating to the specific barriers to communication that arise at the time of mental health diagnosis, and the strategies used to support individuals throughout this process. Methods. An online survey of the beliefs and practices of 131 mental health clinicians working in different clinical settings across Australia was conducted. Results. Exploratory factor analysis of the items relating to barriers to communication resulted in three latent factors (‘stigma, diagnosis and risk’; ‘service structure’; and ‘individual circumstances’ such as the person receiving the diagnosis being young, having a culturally and linguistically diverse background or being unwell at the time of conversation). Using linear regression it was found that variance in ‘stigma, diagnosis and risk’ was significantly explained by whether participating clinicians had medical training, their experience working with serious mental health problems, their confidence handling distress and attitude towards diagnosis. Variance in ‘individual circumstances’ was significantly explained by participating clinicians’ confidence handling distress. The most frequently used strategies to support diagnostic discussions centred on the health professionals’ communication skills, gauging the individual's perception of their circumstances, responding with empathy, following-up after discussion, addressing stigma concerns, using collaborative practice and setting up for the conversation. Conclusions. Three main areas for health professionals to reflect on, plan for and ultimately address when discussing news with the individual concerned emerged (‘stigma, diagnosis and risk’; ‘service structure’; and ‘individual circumstances’). Variations in practice indicate that practitioners should be cognisant of their own beliefs and background and how this impacts their communication practice.
(1) H-NMR quantification of major saccharides in açaí raw materials: a comparison of the internal standard methodology with the absolute intensity qNMR method.

INTRODUCTION While the use of internal standard methodology for qNMR is a proven and reliable form of quantification, simplified alternative approaches are needed. Agilent's absolute intensity qNMR utility software is a valuable alternative that has not yet been subjected to validation in the peer-reviewed literature. OBJECTIVE To provide validation of Agilent's absolute intensity qNMR method with a specific application to natural product quantification by measuring saccharide content in açaí materials. METHODS In order to validate the method, calibration test samples of ibuprofen were prepared in DMSO-d6 at nine different concentrations and measured with (1) H-NMR. A minimum of 40 spectra were collected for each sample, and the absolute intensity utility was used for quantification. The same methodology was then applied to the açaí materials, creating triplicates for each of the materials and using 3-(trimethylsilyl)-1-propanesulphonic acid sodium salt in water-d2 as both the solvent and internal standard. (1) H-NMR spectra were collected, and the amounts of glucose, sucrose and fructose were determined using both the internal standard approach and the absolute intensity qNMR method. RESULTS Applying the absolute intensity utility to the ibuprofen samples demonstrated a linear response (R(2) = 0.99943). For the açaí investigations, results obtained from the absolute intensity method were comparable to those obtained from the internal standard approach, with percentage differences ranging from 0.5-6.2%. CONCLUSION This study demonstrates the accuracy, precision and reliability of Agilent's absolute intensity qNMR method. In addition, practical information is provided for assessing the saccharide contents of açaí materials.
Increased cardiovascular mortality in people with schizophrenia: a 24-year national register study

Aims People who have schizophrenia die earlier from somatic diseases than do people in the general population, but information about cardiovascular deaths in people who have schizophrenia is limited. We analysed mortality in all age groups of people with schizophrenia by specific cardiovascular diseases (CVDs), focusing on five CVD diagnoses: coronary heart disease, acute myocardial infarction, cerebrovascular disease, heart failure and cardiac arrhythmias. We also compared hospital admissions for CVDs in people who had schizophrenia with hospital admissions for CVDs in the general population. Methods This national register study of 10 631 817 people in Sweden included 46 911 people who were admitted to the hospital for schizophrenia between 1 January 1987 and 31 December 2010. Information from national registers was used to identify people who had schizophrenia and obtain data about mortality, causes of death, medical diagnoses and hospitalisations. Results CVDs were the leading cause of death in people who had schizophrenia (5245 deaths), and CVDs caused more excess deaths than suicide. The mean age of CVD death was 10 years lower for people who had schizophrenia (70.5 years) than the general population (80.7 years). The mortality rate ratio (MRR) for CVDs in all people who had schizophrenia was 2.80 (95% confidence interval (CI) 2.73–2.88). In people aged 15–59 years who had schizophrenia, the MRR for CVDs was 6.16 (95% CI 5.79–6.54). In all people who had schizophrenia, the MRR for coronary heart disease was 2.83 (95% CI 2.73–2.94); acute myocardial infarction, 2.62 (95% CI 2.49–2.75); cerebrovascular disease, 2.4 (95% CI 2.25–2.55); heart failure, 3.25 (95% CI 2.94–3.6); and cardiac arrhythmias, 2.06 (95% CI 1.75–2.43). Hospital admissions for coronary heart disease were less frequent in people who had schizophrenia than in the general population (admission rate ratio, 0.88 (95% CI 0.83–0.94). In all age groups, survival after hospital admission for CVD was lower in people who had schizophrenia than in the general population. Conclusions People who had schizophrenia died 10 years earlier from CVDs than did people in the general population. For all five CVD diagnoses, mortality risk was higher for those with schizophrenia than those in the general population. Survival after hospitalisation for CVDs in people who had schizophrenia was comparable with that of people in the general population who were several decades older.
Adverse childhood experiences, exposure to a natural disaster and posttraumatic stress disorder among survivors of the 2011 Great East Japan earthquake and tsunami

Aims. To investigate whether adverse childhood experiences (ACEs) modify the impact of exposure to a natural disaster (the 2011 Great East Japan earthquake and tsunami) on the occurrence of posttraumatic stress disorder (PTSD) among older people. Methods. Data were collected as part of the Japan Gerontological Evaluation Study (JAGES), which is an on-going epidemiological survey investigating social determinants of health among older people across Japan. Information on PTSD symptoms based on the Screening Questionnaire for Disaster Mental Health, traumatic exposure to the earthquake (i.e., house damage and loss of relatives/friends during the earthquake/tsunami) and ACEs was obtained from 580 participants aged 65 or older living in Iwanuma City, Miyagi Prefecture, which suffered severe damage as a result of the earthquake and the subsequent tsunami in March 2011. Associations were examined using Poisson regression analysis with a robust variance estimator after adjusting for covariates. Results. The prevalence of PTSD was 9.7% in this population; compared to those with no traumatic experience, the prevalence of PTSD was approximately two times higher among those who experienced the loss of close friends/relatives (PR = 1.84, 95% CI = 1.11–3.03, p = 0.018), or whose house was damaged (PR = 2.15, 95% CI = 1.07–4.34, p = 0.032). ACE was not significantly associated with PTSD. Stratified analyses by the presence of ACE showed that damage due to the earthquake/tsunami was associated with PTSD only among those without ACEs; more specifically, among non-ACE respondents the PR of PTSD associated with house damage was 6.67 (95% CI = 1.66–26.80), while for the loss of a relative or a close friend it was 3.56 (95% CI = 1.18–10.75). In contrast, no statistically significant associations were observed among those with ACEs. Conclusion. Following the Great East Japan earthquake/tsunami in 2011 a higher risk of developing PTSD symptoms was observed in 2013 especially among older individuals without ACEs. This suggests that ACEs might affect how individuals respond to subsequent traumatic events later in life.
Multi-organ involvement and failure in selected accident cases with acute radiation syndrome observed at the Mayak Nuclear Facility

Mayak Production Association (Mayak PA) in the Southern Ural is the first Russian nuclear facility of plutonium production for weapons. Due to the lack of knowledge and experience in operating nuclear facilities, 19 radiation accidents including criticality accidents occurred and 59 individuals developed acute radiation syndrome (ARS) during commissioning and development of Mayak PA (1948–1958). Severe accidents that occurred at this facility are reviewed, and the initial symptoms and clinical courses of ARS in victims are discussed from the perspective of multi-organ involvement and failure.
Receipt and targeting of evidence-based psychosocial interventions for people living with psychoses: findings from the second Australian national survey of psychosis

Aims. Clinical Practice Guidelines (CPGs) recommend evidence-based psychosocial interventions (EBPIs) to improve consumer recovery; however, availability appears limited. We describe receipt of six EBPIs, reported by people with psychoses, and associations with service and consumer characteristics, including indicators of need (eligibility) and benefit (suitability). Methods. Participants in the 2010 Australian national survey of psychosis (n = 1825) were interviewed to assess demographic, functional, mental and physical health characteristics and service use in the previous year. Six EBPIs (Cognitive Behaviour Therapy for psychosis; Family Psycho-Education (FPE); Relapse Prevention Planning (RPP); Skills Training; Supported Employment; and Assertive Community Treatment) were chosen, based on the strength and consistency of CPG recommendations. Associations between receipt of interventions and eligibility and suitability indicators were examined via correlations and χ2. Logistic regression was used to predict receipt of one or more EBPIs and to identify predictors of each individual EBPI. Results. Less than one-quarter of the sample reported receipt of an evidence-based level of any intervention: rates ranged from 3.4% (FPE) to 21.1% (RPP). The model predicting receipt of one or more EBPIs was statistically significant (χ2 (20, n = 1746) = 216.12, p < 0.01) and marginally useful. Nine variables contributed uniquely, of which six were service characteristics. The strongest predictors of receipt were being assigned a psychologist as a case manager (p < 0.01, OR(CI) = 2.36(1.50–3.72)) and accessing a non-clinical mental health support service in the past year (p < 0.01, OR(CI) = 2.01(1.60–2.51)). Conclusions. Prior reports of limited receipt of EBPIs are reinforced. There is patchy evidence for targeting of EBPIs to those who might benefit most. Service characteristics contribute more to the prediction of receipt than clinical characteristics. Greater implementation effort and better targeting are required to bridge evidence-practice gaps, including improved evidence-based practice literacy among professionals and needs-based service re-design to improve provision and optimise consumer outcomes.
