Hepatic vagus nerve regulates Kupffer cell activation via α7 nicotinic acetylcholine receptor in nonalcoholic steatohepatitis

Abstract

Background

Nonalcoholic fatty liver disease ranges from simple steatosis to nonalcoholic steatohepatitis (NASH). Kupffer cells play a central role in promoting hepatic inflammation, which leads to the development of NASH. We investigated the anti-inflammatory effect of hepatic vagus-mediated stimulation of the α7 nicotinic acetylcholine receptor (α7nAChR) on Kupffer cells in NASH pathogenesis.

Methods

Wild-type (WT) mice undergoing hepatic vagotomy (HV) were fed a methionine- and choline-deficient (MCD) diet for 1 week. α7nAChR knockout (α7KO) chimeric mice were generated by transplanting α7KO bone marrow cells into irradiated and Kupffer cell-deleted WT recipients. Kupffer cells were isolated from WT mice and treated with α7nAChR agonist under stimulation by lipopolysaccharide and/or palmitic acid.

Results

HV aggravated MCD diet-induced NASH in both steatosis and inflammation. The hepatic inflammatory response, including the upregulation of tumor necrosis factor alpha (TNFα), interleukin (IL)-12, and monocyte chemoattractant protein 1 (MCP-1), was accelerated in HV mice, accompanied by the downregulation of PPARα pathway genes. Kupffer cells were highly activated via the phosphorylation and nuclear translocation of nuclear factor-kappa B (NF-κB) in MCD diet-fed HV mice. The α7nAchR agonist suppressed the inflammatory response of primary Kupffer cells induced by lipopolysaccharide and palmitic acid by attenuating the NF-κB cascade. α7KO chimeric mice fed an MCD diet for 1 week developed advanced NASH with highly activated Kupffer cells. The hepatic expression of TNFα, IL-12, and MCP-1 was upregulated in α7KO chimeric mice, accompanied by abnormal lipid metabolism.

Conclusions

Hepatic vagus activity regulates the inflammatory response of Kupffer cells via α7nAChR in NASH development.

Very early onset schizophrenia (VEOS) is a chronic and debilitating psychiatric disorder and has received too little attention in the research literature. Previous studies suggested that VEOS tended to have a worse prognosis and outcome than adult onset schizophrenia. Autism spectrum disorder (OSD) is a life-long impairing heterogeneous disorder, characterized by severe and pervasive impairments in multiple areas of psychological development. According to the literature, co-occurrence of OSD and VEOS is a very rare condition. This paper reports on a case diagnosed as OSD with a VEOS comorbidity. This paper aims to review these two psychopathologies differantial diagnosis, common and different clinical features, neuroimaging findings and genetic and environmental etiologies in the light of the literature.

Objective: The aim of the present study was to evaluate the effect of posttraumatic stress disorder (PTSD) symptoms measured with the PTSD Checklist Civilian (PCL-C) version on severity of alcohol related problems, while controlling the effects of anxiety and depression in a sample of inpatients with alcohol use disorder (AUD). Method: Participants (n=190) were evaluated with the Beck Depression Inventory (BDI), the State-Trait Anxiety Inventory State subscale (STAI-S), the PTSD Checklist Civilian (PCL-C) version and the Michigan Alcohol Screening Test (MAST). Results: Although severity of the state anxiety predicted the severity of alcohol related problems in the first and depression predicted in the second step of a linear regression model, when severity of PTSD symptoms was included in the analysis it was the only independent variable that predicted the severity of alcohol related problems, while the state anxiety and depression were no longer predictors. Conclusion: These findings suggest that severity of PTSD symptoms is related with severity of alcohol related problems, independent from severity of state anxiety and depression among inpatients with AUD.

Evaluation of hypothalamo-pituitary-adrenal axis by using dexamethasone suppression test in patients with panic disorder and generalized anxiety disorder Objective: The aim of this study was to investigate the role of hypothalamo-pituitary-adrenal (HPA) axis on the pathophysiology of anxiety disorders by examining the HPA axis activity in paitents with panic disorder (PD) and generalized anxiety disorder (GAD). Method: Serum concentrations of cortisol and dehydroepiandrosterone-sulfate (DHEA-S) were measured at baseline and post dexamethasone suppression test (DST) in patients with PD (n=24), GAD (n=21) and in healthy controls (n=20). Results: The basal cortisol levels in GAD group were found lower than those of the patients with PD and healthy controls. Cortisol suppression by dexamethasone in GAD group was found to be lower than PD patients and healthy controls. Basal and postdexamethasone DHEA-S levels in the patients with PD and GAD were similar to those of the healthy controls. Conclusion: Lower cortisol levels and inadequate cortisol suppression on DST in GAD patients may suggest a down-regulation in both corticotropin releasing hormone (CRH) and glucocorticoid receptors (GR) in the central nervous system.

Piloting a Statewide Home Visiting Quality Improvement Learning Collaborative

Abstract

Objective To pilot test a statewide quality improvement (QI) collaborative learning network of home visiting agencies. Methods Project timeline was June 2014–May 2015. Overall objectives of this 8-month initiative were to assess the use of collaborative QI to engage local home visiting agencies and to test the use of statewide home visiting data for QI. Outcome measures were mean time from referral to first home visit, percentage of families with at least three home visits per month, mean duration of participation, and exit rate among infants <6 months. Of 110 agencies, eight sites were selected based on volume, geography, and agency leadership. Our adapted Breakthrough Series model included monthly calls with performance feedback and cross-agency learning. A statewide data system was used to generate monthly run charts. Results Mean time from referral to first home visit was 16.7 days, and 9.4% of families received ≥3 visits per month. Mean participation was 11.7 months, and the exit rate among infants <6 months old was 6.1%. Agencies tested several strategies, including parent commitment agreements, expedited contact after referral, and Facebook forums. No shift in outcome measures was observed, but agencies tracked intermediate process changes using internal site-specific data. Agencies reported positive experiences from participation including more frequent and structured staff meetings. Conclusions for Practice Within a pilot QI learning network, agencies tested and measured changes using statewide and internal data. Potential next steps are to develop and test new metrics with current pilot sites and a larger collaborative.

Under-Five Child Mortality and Morbidity Associated with Consanguineous Child Marriage in Pakistan: Retrospective Analysis using Pakistan Demographic and Health Surveys, 1990–91, 2006–07, 2012–13

Abstract

Objective To assess the combined effect of consanguineous and child marriages (CCM) on children health, which has not previously been explored, either globally or locally. Methods We analyzed secondary data from a series of cross-sectional, nationally representative Pakistan Demographic and Health Surveys 1990–91, 2006–07, and 2012–13. A total of 5406 mothers with 10,164 children were included in the analysis. Child health was assessed by variables such as history of diarrhea, acute respiratory infection (ARI), ARI with fever, Under-5 child mortality (U5CM) and small-size birth (SSB). Associations among variables were assessed by calculating unadjusted Odd Ratios (OR) and adjusted OR (AOR). Results A majority (n = 6,247, 61%) of the births were to mothers having CCM as compare to non-CCM (3917, 39%). There was a significant association between CCM and U5CM during 1990–91 (AOR 1.24, 95% CI 1.03–1.49) and 2006–07 (AOR 1.25, 95% CI 1.05–1.51), and infant mortality in 1990–91 (AOR 1.39, 95% CI 1.05–1.85) and 2006–07 (AOR 1.61, 95% CI 1.17–2.21). A significant association was also found between CCM and SSB infants in the period 2006–07 (AOR 1.19, 95% CI 1.01–1.42) and 2012–13 (AOR 1.22, 95% CI 1.02–1.46). We noted no effect of CCM on diarrhea, ARI, and ARI with fever. Conclusion CCM increases the likelihood of U5CM, infant mortality and SSB infants. Further quantitative and qualitative research should be conducted to assess the effects of environmental, congenital and genetic factors on the health of children born to mothers in CCM.

High throughput sequencing of herbaceous peony small RNAs to screen thermo-tolerance related microRNAs

Abstract

Herbaceous peony (Paeonia lactiflora Pall.) is an ornamental flower with wide applications for landscape. However, its application potential is greatly restricted because it is prone to heat stress injury. Although there are some studies about thermo-tolerance of P. lactiflora which focused on physiological and transcriptional level, the information on post-transcriptional level is lacked. Here, we chose a thermo-tolerant cultivar 'Zifengyu' and a moderately thermo-tolerant cultivar 'Hongyanzhenghui' under the natural long summer heat to investigate heat responsive miRNAs by miRNA sequencing. A total of 24,008,974 and 21,981,360 raw reads were generated from 'Zifengyu' and 'Hongyanzhenghui', respectively, as well as 45,016,796 total sRNAs and 6,297,111 unique sRNAs were obtained. Then 271 conserved and 9 novel miRNAs were identified in 'Zifengyu', while 236 conserved and 11 novel miRNAs were identified in 'Hongyanzhenghui'. Among them, 71 known miRNAs with 272 potential target genes and 3 novel miRNAs with 4 potential target genes were significantly differentially expressed. Expression analysis of the 7 candidate miRNAs previously reported to be regulated by heat stress and their target genes were performed. It showed that miR172c-3p, miR395a, miR397a, miR408-5p and miR827 were up-regulated by heat stress, and expressed much higher in thermo-tolerant cultivar 'Zifengyu', suggesting that they might be involved in heat stress response at the post-transcriptional level. These results could provide a better understanding about the thermos-tolerant mechanism of P. lactiflora on post-transcriptional level.

The Effects of Mental Fatigue on Physical Performance: A Systematic Review

Abstract

Background

Mental fatigue is a psychobiological state caused by prolonged periods of demanding cognitive activity. It has recently been suggested that mental fatigue can affect physical performance.

Objective

Our objective was to evaluate the literature on impairment of physical performance due to mental fatigue and to create an overview of the potential factors underlying this effect.

Methods

Two electronic databases, PubMed and Web of Science (until 28 April 2016), were searched for studies designed to test whether mental fatigue influenced performance of a physical task or influenced physiological and/or perceptual responses during the physical task. Studies using short (<30 min) self-regulatory depletion tasks were excluded from the review.

Results

A total of 11 articles were included, of which six were of strong and five of moderate quality. The general finding was a decline in endurance performance (decreased time to exhaustion and self-selected power output/velocity or increased completion time) associated with a higher than normal perceived exertion. Physiological variables traditionally associated with endurance performance (heart rate, blood lactate, oxygen uptake, cardiac output, maximal aerobic capacity) were unaffected by mental fatigue. Maximal strength, power, and anaerobic work were not affected by mental fatigue.

Conclusion

The duration and intensity of the physical task appear to be important factors in the decrease in physical performance due to mental fatigue. The most important factor responsible for the negative impact of mental fatigue on endurance performance is a higher perceived exertion.

Are Prepubertal Children Metabolically Comparable to Well-Trained Adult Endurance Athletes?

Abstract

It is well acknowledged that prepubertal children have smaller body dimensions and a poorer mechanical (movement) efficiency, and thus a lower work capacity than adults. However, the scientific evidence indicates that prepubertal children have a greater net contribution of energy derived from aerobic metabolism in exercising muscle and reduced susceptibility to muscular fatigue, which makes them metabolically comparable to well-trained adult endurance athletes. For example, the relative energy contribution from oxidative and non-oxidative (i.e. anaerobic) sources during moderate-to-intense exercise, the work output for a given anaerobic energy contribution and the rate of acceleration of aerobic metabolic machinery in response to submaximal exercise are similar between prepubertal children and well-trained adult endurance athletes. Similar conclusions can be drawn on the basis of experimental data derived from intra-muscular measurements such as type I fibre percentage, succinate dehydrogenase enzyme activity, mitochondrial volume density, post-exercise phosphocreatine re-synthesis rate and muscle by-product clearance rates (i.e. H+ ions). On a more practical level, prepubertal children also experience similar decrements in peak power output as well-trained adult endurance athletes during repeated maximal exercise bouts. Therefore, prepubertal children have a comparable relative oxidative contribution to well-trained adult endurance athletes, but a decrease in this relative contribution occurs from childhood through to early adulthood. In a clinical context, this understanding may prove central to the development of exercise-based strategies for the prevention and treatment of many metabolic diseases related to mitochondrial oxidative dysfunction (e.g. in obese, insulin-resistant and diabetic patients), which are often accompanied by muscular deconditioning during adolescence and adulthood.

Long-Term Outcomes and Predictors of Sustained Response in Patients with Intestinal Behcet’s Disease Treated with Infliximab

Abstract

Background

Intestinal Behcet's disease (BD) is a specific subtype of BD. Effective drug therapy for intestinal BD remains elusive.

Aims

To investigate long-term outcomes and identify predictors of sustained response in intestinal BD patients receiving infliximab (IFX) treatment.

Methods

The medical records were reviewed of patients received IFX from September 2012 to March 2016. The cumulative probabilities of sustained response were calculated using the Kaplan–Meier. Predictor factors for sustained response were accessed by receiver operating characteristic curve.

Results

Totally, 27 active intestinal BD patients were enrolled. Sustained responses were observed in 17 patients, after a median follow-up duration 24 months (interquartile range 9–37). The proportion of clinical remission at week 14, 30, and 52 had occurred in 84.6, 70, and 70%, respectively, with the proportion of clinical remission of 69.2, 40, and 55%. The mucosal healing (MH) rate at week 14 was 72%. Kaplan–Meier estimated patients with achievement of clinical and biological responses at week 14 or MH was likely to remain sustained clinical response. ROC curve analysis revealed CRP level (of 6.85 mg/L) at week 14 is a potential predictor for discriminating patients with sustained response from relapse, with an area under the curve values of 0.837.

Conclusions

IFX is effective and safe for induction and maintenance therapy in Chinese patients with moderate-to-severe active intestinal BD. Early achievement of clinical response and mucosal healing might associate long-term response. A lower CRP level seems to be associated with a more benign clinical course.

Genetic Biomarker Prevalence Is Similar in Fecal Immunochemical Test Positive and Negative Colorectal Cancer Tissue

Abstract

Background

Fecal immunochemical test (FIT) screening detects most asymptomatic colorectal cancers. Combining FIT screening with stool-based genetic biomarkers increases sensitivity for cancer, but whether DNA biomarkers (biomarkers) differ for cancers detected versus missed by FIT screening has not been evaluated in a community-based population.

Aims

To evaluate tissue biomarkers among Kaiser Permanente Northern California patients diagnosed with colorectal cancer within 2 years after FIT screening.

Methods

FIT-negative and FIT-positive colorectal cancer patients 50–77 years of age were matched on age, sex, and cancer stage. Adequate DNA was isolated from paraffin-embedded specimens in 210 FIT-negative and 211 FIT-positive patients. Quantitative allele-specific real-time target and signal amplification assays were performed for 7 K-ras mutations and 10 aberrantly methylated DNA biomarkers (NDRG4, BMP3, SFMBT2_895, SFMBT2_896, SFMBT2_897, CHST2_7890, PDGFD, VAV3, DTX1, CHST2_7889).

Results

One or more biomarkers were found in 414 of 421 CRCs (98.3%). Biomarker expression was not associated with FIT status, with the exception of higher SFMBT2_897 expression in FIT-negative (194 of 210; 92.4%) than in FIT-positive cancers (180 of 211; 85.3%; p = 0.02). There were no consistent differences in biomarker expression by FIT status within age, sex, stage, and cancer location subgroups.

Conclusions

The biomarkers of a currently in-use multi-target stool DNA test (K-ras, NDRG4, and BMP3) and eight newly characterized methylated biomarkers were commonly expressed in tumor tissue specimens, independent of FIT result. Additional study using stool-based testing with these new biomarkers will allow assessment of sensitivity, specificity, and clinical utility.

Reduced IL-37 Production Increases Spontaneous Chemokine Expressions in Colon Epithelial Cells

Abstract

Background and Aim

Microscopic colitis, comprising collagenous colitis and lymphocytic colitis, is a common cause of chronic diarrhea. Previously, we showed enhanced chemokine productions in microscopic colitis patients, indicating dysregulated immune cell chemotaxis in the immunopathogenesis. We also showed decreased mRNA of IL-37, mainly regarded as an anti-inflammatory cytokine, in the colonic mucosa of these patients, potentially an important factor for the chronicity of the colitis. Our aim in this study was to understand the possible role of IL-37 in chemokine production using a cell line model.

Methods

A colon epithelial cell line, T84, was stimulated with the TLR5 ligand flagellin. IL-37 protein production was reduced 20% using the CRISPR/Cas9 system, and the changes in chemokine mRNA and protein expressions were compared to cells transfected with empty plasmid.

Results

The 20% reduction in IL-37 protein levels spontaneously increased CCL5, CXCL8, CXCL10, and CXCL11 mRNA and protein expressions. CCL2 mRNA and protein levels were enhanced upon TLR5 stimulation. CCL3, CCL20, and CX3CL1 mRNA expressions were increased either spontaneously or following TLR5 stimulation, whereas CCL4 and CCL22 mRNA expressions were significantly decreased.

Conclusions

Even a minor decrease in the ability of colon epithelial cells to produce IL-37 results in altered chemokine expression, mainly an increase in the production of several chemokines. Our results indicate that a decreased IL-37 expression by colon epithelial cells may be an important factor for increasing the recruitment of immune cells and subsequently developing microscopic colitis.

Nerve conduction studies during various phases of menstrual cycle

2017-01-02T08-10-05Z
Source: National Journal of Physiology, Pharmacy and Pharmacology
Surbhi Vashisht, Anuj Chawla, Rajneesh Kumar Joshi.
Background: Menstrual cycle is associated with hormonal fluctuations during various phases. Changes in estrogen levels are associated with swings in mood and cognitive functions. Against this background, this study was undertaken to observe differences in various parameters of nerve conduction during various phases of menstrual cycle. Aims and Objectives: Observe changes in sensory and motor nerve conduction during various phases of menstrual cycle. Materials and Methods: A cross-sectional study was carried out on 35 healthy female volunteers aged 18-35 years. Nerve conduction studies consisting of sensory and motor conduction velocity, distal latencies, compound muscle action potential amplitude, sensory nerve action potential amplitude, and the F wave latencies were carried out on ulnar, common peroneal, and the sural nerve during four phases of the menstrual cycle. Statistical analysis of the results was done using analysis of variance. Results: Nerve conduction parameters did not vary significantly with various phases of the menstrual cycle. Conclusions: Although synaptic conduction and release of neurotransmitters is modulated by estrogen and progesterone but these appear to have no significant role on the normal axonal conduction. Hence, no significant changes were observed in peripheral nerve conduction across various phases of the menstrual cycle.

Background: According to International Diabetes Federation diabetes Atlas in India, 42.2 million people have prediabetes. Risk of development of diabetes in such people is high. Objectives: To determine the prevalence of impaired fasting glucose (IFG) in urban areas of Gwalior and to find a relation between IFG and various anthropometric variables. Materials and Methods: It was a cross-sectional community-based survey done on 1000 participants in city of Gwalior between June 2014 and October 2015. Fasting capillary blood glucose was determined using a glucometer after 8 h of fasting. Association between IFG and anthropometric parameters, total cholesterol, triglyceride, alcohol intake, and smoking was obtained. Results: Out of 1000 participants screened, 229 (22.9%) had IFG; hence, prevalence was 22.9%. Mean age, body mass index (BMI), waistto-hip ratio (WHR), and fasting blood glucose (FBG) of participants with IFG were 37.85 ± 3.23 years, 25.29 ± 2.60 kg/m2, 0.943 ± 0.05, and 108.83 ± 5.00 mg/dl, respectively. IFG was mostly observed in male population (69.86%), with non-vegetarian diet (68.56%) and population who had a family history of diabetes mellitus (74.67%). Out of 229 participants with IFG, 162 (70.74%) had BMI >23 kg/m2, 203 (88.64%) had raised WHR, 142 (62%) had raised total cholesterol level, 97 (42.35%) were alcoholic, and 126 (55.02%) were smokers. There was a significant difference in mean BMI (P = 0.001), WHR (P = 0.023), and FBG (P = 0.0001) in IFG population as compared to euglycemic population. In conclusion, the present study has shown that the prevalence of IFG was 22.9% with males showing a higher prevalence. Conclusion: Participants with raised BMI, WHR, and non-vegetarian diet had higher incidence of IFG. Participants having IFG had raised total cholesterol and significantly raised triglyceride levels. No significant association was found between IFG and smoking/alcohol.

Alex Mirara, Timothy Maitho, Ursulla Achieng Okoth.
This study investigated the differences between the various legal entities of service provider organizations which provide the privatized artificial insemination services in Nyeri County, Kenya. The study found that 89.5% of the service providers were serving as private entities, 7.0% were in Cooperative societies while 3.5% were serving as farmers self-help groups. All the AI practitioners used motorcycles for transport and stored semen in liquid nitrogen tanks. Government support to AI service providers was only in form of training which was received by 21% of the service providers. Non-governmental organizations also provided training to 17.5% of the respondents. However, these organizations provided financial credit to 3.5% as well as equipment support to 3.5% of the service providers. It was concluded that private AI service providers have a potential of performing better than Cooperative societies or self-help groups despite the benefits of farmers having a jointly owned service.
