Does β-caryophyllene protect against renal dysfunction following ischemia-reperfusion injury in the rat?

INTRODUCTION Renal ischemia-reperfusion injury (IRI) causes renal functional alterations which may lead to permanent renal impairment. β-caryophyllene (BCP), a natural bicyclic sesquiterpene, is an important constituent of many edible plants including spices. It is an FDA-approved food additive which possesses potent anti-inflammatory and antioxidant activities and has been shown to protect against chemotherapeutics-induced organ toxicities and against ischemic injuries to heart, liver and brain. Oxidative stress and inflammation is a main accompaniment of renal dysfunction, however, the effect of BCP on IRI-induced renal dysfunction has not been investigated yet and therefore the aim of this study was to investigate the effect of BCP on IRI-induced renal dysfunction. METHODS Wistar rats underwent left renal warm ischemia for 40 minutes. G-BCP (n=13) received oral BCP (50 mg/kg/day) dissolved in a vehicle starting 7 days prior to IRI and continued 7 days thereafter when the renal functions of both kidneys and the markers of oxidative stress and pro-inflammatory cytokines were measured. G-Vx (n=13) underwent similar protocol but received vehicle only. RESULTS IRI affected hemodynamic (renal blood flow and glomerular filtration rate) and tubular (urine volume, total and fractional urinary sodium excretion) parameters in the left ischemic kidney in G-Vx. Though, BCP did not affect any of these alterations in the ischemic kidney (P>0.05 for all). However, it attenuated the alterations in malondialdehyde (MDA) and glutathione (GSH) in the left ischemic kidney in G-BCP compared to G-Vx (9.3±2.1 vs. 4.8±1.0, P=0.047 and 18.1±2.5 vs. 13.6±1.7, P=0.09, respectively). CONCLUSION Our study results demonstrate that BCP attenuated the alterations in some of the oxidative stress markers. However, these were not translated in to the protective effects on the haemodynamic and tubular glomerular functions when measured seven days post-IRI. This suggests that BCP has a weak reno-protective effect under ischemic conditions.
A Hierarchical Deep Fusion Framework for Egocentric Activity Recognition using a Wearable Hybrid Sensor System

Recently, egocentric activity recognition has attracted considerable attention in the pattern recognition and artificial intelligence communities because of its wide applicability in medical care, smart homes, and security monitoring. In this study, we developed and implemented a deep-learning-based hierarchical fusion framework for the recognition of egocentric activities of daily living (ADLs) in a wearable hybrid sensor system comprising motion sensors and cameras. Long short-term memory (LSTM) and a convolutional neural network are used to perform egocentric ADL recognition based on motion sensor data and photo streaming in different layers, respectively. The motion sensor data are used solely for activity classification according to motion state, while the photo stream is used for further specific activity recognition in the motion state groups. Thus, both motion sensor data and photo stream work in their most suitable classification mode to significantly reduce the negative influence of sensor differences on the fusion results. Experimental results show that the proposed method not only is more accurate than the existing direct fusion method (by up to 6%) but also avoids the time-consuming computation of optical flow in the existing method, which makes the proposed algorithm less complex and more suitable for practical application.
Cafeteria Diet Consumption during Lactation in Rats, Rather than Obesity Per Se, alters miR‐222, miR‐200a, and miR‐26a Levels in Milk

SCOPE The aim of the present study is to investigate in nursing rats the impact of cafeteria-diet feeding during lactation (cafeteria dams) on specific miRNA levels in breast milk and to discern them from the effects of maternal adiposity per se (postcafeteria dams). METHODS AND RESULTS Milk samples are collected from control, cafeteria, and postcafeteria dams at three time points of lactation (days 5, 10, and 15) and levels of selected miRNAs (miR-222, miR-203, miR-200a, miR-103, miR-27a, and miR-26a) were determined. Levels in milk of miR-222 rise while miR-103 and miR-27 fall throughout lactation. Moreover, at day 15 of lactation, cafeteria dams present higher miR-222 and lower miR-200a and miR-26a levels in milk than controls. No differences are found in postcafeteria dams compared with controls. At weaning, the offspring of cafeteria dams, but not the offspring of postcafeteria dams, displays lower expression levels of Cdkn1c (a validated target gene of miR-222) in liver than controls. CONCLUSION Cafeteria diet intake in nursing rats, rather than obesity per se, leads to alterations in specific miRNA levels, which, through the milk supply, may alter expression of target genes and potentially affect offspring phenotype.
Influence of peer-based rehabilitation interventions for improving mobility and participation among adults with mobility disabilities: a systematic review

Abstract Purpose: The prevalence of mobility disability reaches up to 20.5% among older adults. Mobility is a key factor of participation, thus rehabilitation interventions often aim to improve mobility and participation. Peer-based approaches to intervention delivery have become increasingly common. This study aims to identify peer-based rehabilitation interventions and summarize their influence on mobility and participation among individuals with mobility disabilities. Method: A systematic review was conducted using CINALH, EMBASE, MEDLINE, and PsycINFO. Articles that evaluated peer-based rehabilitation interventions for individuals with a mobility disability and assessed mobility or participation, as defined in the International Classification of Functioning, Disability and Health framework, were included. Study quality was assessed using the Physical Therapy Evidence Database and the Quality Assessment Tool for Before-After Studies With No Control Group. Results: Thirteen peer-based studies were identified. Six peer-led studies evaluated participation and two evaluated mobility. Seven professional-led studies evaluated participation and six evaluated mobility. Randomized controlled trials had fair to high quality. The quality of pre–post studies ranged from poor to good. Conclusion: Peer-based interventions should not be overlooked as a potential intervention strategy, but further research is needed to establish their influence on mobility and participation. Implications for rehabilitation Peers offer a unique model of intervention that could support clinicians in their effort to improve mobility and participation outcomes for individuals with disabilities. There are currently two main models of peer-based interventions in rehabilitation: professional-led (peers assist professionals to facilitate the intervention) and peer-led interventions (peers facilitate the intervention). Both professional-led and peer-led models of intervention could be helpful in facilitating participation and in increasing mobility.
Alcohol Abstainer Status and Prazosin Treatment in Association with Changes in Posttraumatic Stress Disorder Symptoms in Veterans with Comorbid Alcohol Use Disorder and Posttraumatic Stress Disorder

BACKGROUND The noradrenergic system has been implicated in alcohol use disorder (AUD) and posttraumatic stress disorder (PTSD), with adrenergic agents reducing drinking in individuals with AUD and improving sleep disturbances in individuals with PTSD. In a recent clinical trial, prazosin, an α1-adrenergic antagonist, was not superior to placebo in reducing PTSD symptoms, sleep problems, or alcohol consumption in a comorbid population; however, patients in both treatment conditions improved in all symptom domains over the course of treatment. It remains unknown whether alcohol abstinence is related to changes in PTSD symptoms and medication effects in individuals with this comorbidity. METHODS Veterans with comorbid alcohol dependence and PTSD (n = 96) were randomized to prazosin (16 mg) or placebo in a 12-week outpatient, double-blind clinical trial. In this secondary data analysis, we examined main effects of alcohol abstainer status (abstainer vs. nonabstainer), treatment, and their interaction on changes in PTSD symptoms over time using linear mixed models. RESULTS There was a main effect of alcohol abstainer status on symptoms of PTSD (p = 0.03), such that nonabstainers had lower total Clinician-Administered PTSD Scale (CAPS) scores than abstainers. There was a significant treatment by alcohol abstainer status interaction (p = 0.01); specifically, among placebo-treated individuals, those who did not abstain from alcohol had lower total CAPS scores compared to alcohol abstainers. Within the prazosin-treated group, abstainers and nonabstainers did not differ on total CAPS scores. Results were similar for the avoidance (p = 0.02), reexperiencing (p = 0.01), and hyperarousal (p = 0.04) subscales, such that placebo-treated nonabstainers had lower CAPS scores overall. CONCLUSIONS Overall, prazosin treatment was not significantly related to changes in PTSD symptoms over the course of the 12-week clinical trial in a comorbid population. Interestingly, placebo-treated alcohol nonabstainers had a significant reduction in PTSD symptoms. Whether placebo-treated individuals continued to use alcohol because of ongoing symptoms of PTSD is not known.
An Approach to the Patient With Chronic Undiagnosed Abdominal Pain

Abdominal pain is a common reason for referral to a gastroenterologist. The workup of patients with chronic abdominal pain can be extremely challenging as clinicians are responsible for determining whether the patient can be observed or treated symptomatically or this abdominal pain heralds a more systemic disease. The differential is typically wide and given the innervation of the abdomen, localization of abdominal pain does not always provide clear insight into the etiology. This review attempts to help the gastroenterologist narrow down that broad differential and focus on key elements of the patient visit. We emphasize the importance of a detailed history from the patient, along with review-specific details of their history and physical examination that can clue one in about the etiology of the abdominal pain. We review the causes of diffuse abdominal pain that may not first be considered along with uncommon causes of localized abdominal pain. We also review the functional causes of abdominal pain and the importance of identifying these disorders, to avoid unnecessary testing that commonly occurs with these patients.
An image is worth a thousand words

Introduction This case involved a 15-year-old boy, who slipped and impaled his left hand on a wooden beam. An initial anterior–posterior radiograph was obtained prior to referral to plastic surgery for further management (figure 1). Figure 1 Clinical photographs and initial X-ray taken of the impalement injury. Clinical examination was restricted due to access. The patient reported general pain on limited movement of all digits but normal neurology. He received appropriate initial treatment of broad-spectrum antibiotics and tetanus care in the emergency department. His medical and social history were unremarkable. Question What is the next most appropriate intervention? Immediate removal of the impaled structure under tourniquet control in an operating theatre. Immediate removal of the impaled structure in the emergency department under nerve block. Further imaging is needed. Urgent surgical consultation.
Avoiding chemotherapy prescribing errors: Analysis and innovative strategies

At Freiburg University Medical Center, chemotherapy prescriptions are processed via a computerized physician order entry (CPOE) tool and clinically checked by a designated chemotherapy surveillance team. Any error detected is reported instantly, corrected, and prospectively recorded. The objective of the current study was to gain insight into the causes, potential consequences, and future preventability of chemotherapy prescribing errors.
Identification of Chromosomal Regions Linked to Diabetic Nephropathy: A Meta-Analysis of Genome-Wide Linkage Scans.

AIMS Diabetic nephropathy (DN) has become a serious public health problem. Genetic factors are involved in the pathogenesis of DN, but the exact mode of inheritance is still unknown. Genome-wide linkage scans (GWLS) have produced inconclusive or inconsistent results. In an effort to test consistency and provide more conclusive results, we applied a heterogeneity-based genome search meta-analysis (HEGESMA) to GWLS regarding DN. MATERIALS AND METHODS We combined results from eight GWLS in the primary analysis and nine GWLS for a conditional analysis about DN for both diabetes types, as well as in each type of diabetes and ethnicity in subgroup analyses. RESULTS HEGESMA identified cytogenetic locations that rank highly on average in terms of linkage statistics across multiple genome scans, taking into consideration the magnitude of heterogeneity of the results between scans. Main analyses: Our meta-analysis identified 13 cytogenetic locations (bins) with statistical significance (Prank ≤ 0.05), 11 of which were significant in both weighted and unweighted analyses located on chromosomes 1q, 3q, 4p, 5q, 7q, 15q, 16p, 17q, 19q, and 22p. In addition, four novel regions (5q11.2-5q14.3, 5q23.2-5q34, 17q24.3-17q25.3, and 22q12.3-22q13.3) were identified. Seven bins on chromosomes 4p, 5q, 7q, 15q, 22p, and 22q were common between both types of diabetes and in all subgroup analyses, in addition 5q14.3-5q23.2 was significant across all analyses. Conditional analyses: meta-analysis identified nine different cytogenetic locations, among which 7p22.3-7p15.3 was significant only in type 2 diabetes mellitus conditional analysis. Ethnicity subgroup analyses identified 11 different cytogenetic locations, 5 out of which are novel findings. However, none of the chromosomal regions reached genome-wide statistical significance (Prank < 0.00042). DISCUSSION This meta-analysis provides evidence for linkage for nine novel cytogenetic regions that should be further investigated for genes that confer susceptibility to DN.
Parathyroid hormone initiates dynamic NHERF1 phosphorylation cycling and conformational changes that regulate NPT2A-dependent phosphate transport

Na+-H+ exchanger regulatory factor-1 (NHERF1) is a PDZ protein that scaffolds membrane proteins, including sodium–phosphate co-transport protein 2A (NPT2A) at the plasma membrane. NHERF1 is a phosphoprotein with 40 Ser and Thr residues. Here, using tandem MS analysis, we characterized the sites of parathyroid hormone (PTH)-induced NHERF1 phosphorylation and identified 10 high-confidence phosphorylation sites. Ala replacement at Ser46, Ser162, Ser181, Ser269, Ser280, Ser291, Thr293, Ser299, and Ser302 did not affect phosphate uptake, but S290A substitution abolished PTH-dependent phosphate transport. Unexpectedly, Ser290 was rapidly dephosphorylated and rephosphorylated after PTH stimulation, and we found that protein phosphatase 1α (PP1α), which binds NHERF1 through a conserved VxF/W PP1 motif, dephosphorylates Ser290. Mutating 257VPF259 eliminated PP1 binding and blunted dephosphorylation. Tautomycetin blocked PP1 activity and abrogated PTH-sensitive phosphate transport. Using fluorescence lifetime imaging (FLIM), we observed that PTH paradoxically and transiently elevates intracellular phosphate. Added phosphate blocked PP1α-mediated Ser290 dephosphorylation of recombinant NHERF1. Hydrogen–deuterium exchange MS revealed that β-sheets in NHERF1's PDZ2 domain display lower deuterium uptake than those in the structurally similar PDZ1, implying that PDZ1 is more cloistered. Dephosphorylated NHERF1 exhibited faster exchange at C-terminal residues suggesting that NHERF1 dephosphorylation precedes Ser290 rephosphorylation. Our results show that PP1α and NHERF1 form a holoenzyme and that a multiprotein kinase cascade involving G protein–coupled receptor kinase 6A controls the Ser290 phosphorylation status of NHERF1 and regulates PTH-sensitive, NPT2A-mediated phosphate uptake. These findings reveal how reversible phosphorylation modifies protein conformation and function and the biochemical mechanisms underlying PTH control of phosphate transport.
The safety and efficacy of tPA intravenous thrombolysis for treating acute ischemic stroke patients with a history of cerebral hemorrhage

Alteplase (tPA) intravenous thrombolysis is an effective treatment for acute ischemic stroke (AIS) when administered within 4.5 h of initial stroke symptoms. Here, its safety and efficacy were evaluated among AIS patients with a previous history of cerebral hemorrhage. Patients who arrived at the hospital within 4.5 h of initial stroke symptoms and who were treated with tPA intravenous thrombolysis or conventional therapies were analyzed. The 90-day modified Rankin scale (90-d mRS) was used alongside mortality and incidence of symptomatic intracerebral hemorrhage (SICH) rates to evaluate the curative effect of these therapies. Among 1,694 AIS patients, 805 patients were treated with intravenous thrombolysis, including patients with (n=793) or without (n=12) a history of cerebral hemorrhage, and the rate of incidence of SICH significantly differed between them (8.3 vs 4.3%, P=0.039). No significant difference was found in 90-d mRS measurements (41.7 vs 43.6%, P=0.530) and 90-d mortality rates (8.3 vs 6.5%, P=0.946). A total of 76 AIS patients with a history of cerebral hemorrhage received tPA thrombolytic therapy (n=12) or conventional therapy (n=64), and a significant difference was noted in the 90-d mRS scores between the two groups (41.7 vs 23.4%, P=0.029), while no significant difference was found in SICH measurements (8.3 vs 4.6%, P=0.610) and 90-d mortality rates (8.3 vs 9.4%, P=0.227). A history of cerebral hemorrhage is not an absolute contraindication for thrombolytic therapy; tPA intravenous thrombolysis does not increase SICH measurements and mortality rates in patients with a history of cerebral hemorrhage, and they may benefit from thrombolytic therapy.
Vitamin B6 catabolism and lung cancer risk: results from the Lung Cancer Cohort Consortium (LC3)

BACKGROUND Increased vitamin B6 catabolism related to inflammation, as measured by the PAr index (the ratio of 4-pyridoxic acid over the sum of pyridoxal and pyridoxal-5'-phosphate), has been positively associated with lung cancer risk in two prospective European studies. However, the extent to which this association translates to more diverse populations is not known. MATERIALS AND METHODS For this study, we included 5323 incident lung cancer cases and 5323 controls individually matched by age, sex, and smoking status within each of 20 prospective cohorts from the Lung Cancer Cohort Consortium. Cohort-specific odds ratios (ORs) and 95% confidence intervals (CIs) for the association between PAr and lung cancer risk were calculated using conditional logistic regression and pooled using random-effects models. RESULTS PAr was positively associated with lung cancer risk in a dose-response fashion. Comparing the fourth versus first quartiles of PAr resulted in an OR of 1.38 (95% CI: 1.19-1.59) for overall lung cancer risk. The association between PAr and lung cancer risk was most prominent in former smokers (OR: 1.69, 95% CI: 1.36-2.10), men (OR: 1.60, 95% CI: 1.28-2.00), and for cancers diagnosed within 3 years of blood draw (OR: 1.73, 95% CI: 1.34-2.23). CONCLUSION Based on pre-diagnostic data from 20 cohorts across 4 continents, this study confirms that increased vitamin B6 catabolism related to inflammation and immune activation is associated with a higher risk of developing lung cancer. Moreover, PAr may be a pre-diagnostic marker of lung cancer rather than a causal factor.
Person centered care in neurorehabilitation: a secondary analysis

Abstract Person centered care has been described as being in its ascendency, despite some of the complexities of embedding it within healthcare systems. The emphasis of research now seems to be moving toward the promotion of cultures of care that support the efforts of practitioners. Informed by some of the principles of positive deviancy, where some of the solutions for change can be found within existing cultures and practices, this paper aimed to identify examples of person-centered care in existing practice. Reporting on a thematic analysis of qualitative datasets from three preexisting projects, we constructed four themes from these data: (1) That patient experience and needs should always be understood in terms of their difficult new reality; (2) the need for a relational orientation in care; (3) the importance of treating trust as a currency; and, (4) efficacy in rehabilitation is co-constructed, and enabled by the efforts of clinicians. Identifying positive examples of care, enacted irrespective of the framework of care they are found within, may provide opportunities to critically reflect on practice. The context for care and the extent to which that context constrains or makes possible person-centered care in practice will also be discussed. IMPLICATIONS FOR REHABILITATION Cultures of care are central to enhancing person-centered practice. Care begins with recognition of patient’s difficult new reality. Building trust helps enable capacity for improvement.
Do People Believe That They Are More Deontological Than Others?

The question of how we decide that someone else has done something wrong is at the heart of moral psychology. Little work has been done to investigate whether people believe that others’ moral judgment differs from their own in moral dilemmas. We conducted four experiments using various measures and diverse samples to demonstrate the self–other discrepancy in moral judgment. We found that (a) people were more deontological when they made moral judgments themselves than when they judged a stranger (Studies 1-4) and (b) a protected values (PVs) account outperformed an emotion account and a construal-level theory account in explaining this self–other discrepancy (Studies 3 and 4). We argued that the self–other discrepancy in moral judgment may serve as a protective mechanism co-evolving alongside the social exchange mechanism and may contribute to better understanding the obstacles preventing people from cooperation.
Circuit based anti-correlation, attention orienting, and major depression

Major depression is a multidimensional disorder producing emotional dysregulation, cognitive impairment, and neuro-vegetative symptoms. A pathophysiological model of depression needs to explain how these dimensions interact to produce specific clinical phenotypes and how these interactions may predict remission to specific treatments. It is unlikely that major depression results from discrete brain lesions. Here we propose to define major depression as a disorder of neural networks. We review evidence suggesting that the dynamics of neural networks involved in allocation of attention resources to the internal and external world contribute to cognitive impairment, increased self-focus, and dysfunctional saliency detection in depression. We describe cognitive and emotional tasks that reveal abnormal cooperation between the Central Executive Network and the Default Mode Network. Finally we suggest that depression is associated with increased social rejection sensitivity. Studies on social rejection will shed light on how attachment relates to impairment in allocation of attention resources to produce depressive symptoms such as rumination and cognitive problems.
