Objective

Hoarding behavior is not limited to obsessive-compulsive disorder (OCD) alone. With the objective of highlighting the association between hoarding behavior and common psychiatric disorders, we explored its occurrence in psychiatric inpatients and co-occurrence with Axis I diagnoses.

Methods

In this prospective cohort study, we enrolled adult psychiatric inpatients by simple random sampling at an urban, community-based, academic medical center. Patients were screened for hoarding using the validated Hoarding Rating Scale-Interview, and those meeting criteria for clinically significant hoarding were assessed for Axis I disorders.

Results

Clinically significant hoarding was observed in 33% of the 200 acute psychiatry patients admitted to the study. Mood disorders were positively associated with hoarding (p?=?0.033), whereas psychotic spectrum disorders had a weaker association with it (p?=?0.015).

Conclusion

This study indicates a need for clinicians to be mindful that hoarding manifests in many forms of mental illness and is not limited to OCD alone.  相似文献

Background

Inhibition of calpain activity provides neuroprotection in multiple central nervous system injury, but the role and mechanism of calpain in subarachnoid hemorrhage (SAH) remain unclear. This study was undertaken to determine the effects of inhibition of calpain on neurological deficit and neuronal apoptosis following experimental SAH.

Methods

The endovascular perforation model of SAH was produced in male Sprague-Dawley rats. Rats were administered calpeptin 50 μg, intracerebroventricular injection, 30 minutes before induction of SAH. After 72 hours, the method of Evans blue dye extravasation and wet/dry method were used for determination of blood-brain barrier permeability and brain edema, Western blot analysis and immunohistological staining were used to evaluate neuronal apoptosis.

Results

The intracellular Ca2+ level and calpain activity was significantly elevated in basal cortex after SAH. Calpain inhibitor calpeptin reduces brain water content and Evans blue dye extravasation, improves neurobehavioral deficits after SAH. Importantly, calpeptin treatment significantly reduces activation of caspase-3, caspase-9, caspase-12 and poly ADP ribose polymerase and the number of apoptotic neurons in basal cortex after SAH.

Conclusion

The present study suggested that calpeptin is neuroprotective in early brain injury after SAH through antiapoptotic effect.  相似文献

Background

Correct diagnosis of cerebral stroke type, hemorrhagic or ischemic, is essential in the early stage to establish the optimum treatment. The diagnosis is mainly determined based on imaging studies. Other more available diagnostic methods are desirable, such as blood sample examination. Lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) is very important in vascular dysfunction induced by oxidized low-density lipoprotein, including cell apoptosis. The present study evaluated LOX-1 as a biomarker for cerebral stroke.

Subjects and Methods

Patients with newly diagnosed stroke were prospectively enrolled between February and July 2014. LOX-1 serum values were measured twice, within 24 hours and 2 months after the onset.

Results

A total of 16 patients were enrolled; 7 patients with intracerebral hemorrhage (ICH) and 9 patients with cerebral infarction. Median LOX-1 values of patients with ICH and infarction in the acute phase were 1825.8 and 593.9 pg/mL, respectively, significantly higher in patients with ICH than in patients with infarction (P < .0001).

Conclusion

LOX-1 serum level has potential as a biomarker of ICH.  相似文献

Background

Current pharmacological treatments and psychotherapeutic approaches often have adverse effects or are ineffective in late-life cognitive and mental illnesses. Mind-body interventions offer a holistic approach and are of interest because of potential patient acceptability and scalability.

Objective

To synthesize current evidence on mind-body interventions in treating or preventing mental illnesses and cognitive disorders in older adults.

Search Strategy

A search was conducted using Ovid MEDLINE, EMBASE, and PsycINFO articles published from 1993 to 2017.

Selection Criteria

1) Randomized controlled trials, 2) involving older adults (>60 years old), 3) suffering from mental illness or cognitive decline, 4) comparing mind-body interventions with a control group. Mind-body interventions included: imagery, meditation, prayer, autogenic training, tai chi & variants, and yoga. Control group included: health education, other non-pharmacological interventions, treatment as usual, or no treatment at all.

Data Collection and Analysis

Data included number of patients, age, psychiatric diagnoses, type of intervention, frequency andduration, control conditions, outcomes measures and treatment results.

Results

3916 articles were reviewed and ten met inclusion criteria. Six were on Tai Chi and four assessed meditation-based therapies. Clinically significant improvement in depressive and anxiety symptoms were reported, as well as improvement insomedomains of cognition and reduced risk of cognitive deterioration.

Conclusion

There is increasing evidence that mind-body interventions may potentially be useful in the treatment or prevention of geriatric mental illnesses and cognitive disorders. There are important methodological limitations of the current literature such as small sample sizes, heterogeneous study populations, and varying clinical outcomes.  相似文献

Introduction

Venous phlebitis in Neurosarcoidosis (NS) is rare but is often associated with intracranial hemorrhage (ICH). Imaging findings in such cases have been recently described on susceptibility weighted imaging (SWI).

Case Presentation and Outcome

We report a patient who presented with ICH. Magnetic resonance imaging provided evidence for parenchymal and leptomeningeal involvement while SWI and vessel wall imaging (VWI) helped confirmed NS associated intracranial phlebitis. The patient was subsequently diagnosed with systemic sarcoidosis.

Discussion

The emerging role of VWI and SWI in the diagnosis of this rare entity is discussed.  相似文献

Background

Carotid endarterectomy (CEA) is a standard treatment for carotid artery stenosis, but the incidence after periprocedural myocardial infarction (MI) is not negligible. The mechanism for the higher risk of MI following CEA compared with the carotid artery stenting (CAS) is unclear. We hypothesized that it may be explained by different autonomic nervous responses.

Methods

This prospective, nonrandomized, observational study enrolled 50 patients from 2 centers: 25 underwent CEA and 25 CAS. Cardiac autonomic nervous activity was evaluated using 24-hour high-resolution ambulatory electrocardiography with parameters such as deceleration capacity (DC) and heart rate variability before the procedure, and at 1 week and 1-3 months after the procedure.

Results

One week after CEA, decreased DC and increased acceleration capacity were recognized. Standard deviation of sequential 5-minute NN interval means and the low-frequency and high-frequency components were all decreased. By the later phase measurement, these changes returned to baseline or beyond. The results suggest that diminished autonomic activity reversed to excessive parasympathetic dominance. In contrast, the patients treated by CAS showed no remarkable autonomic modification in the early or later phases.

Conclusions

Distinct changes of sympathovagal response observed after CEA coincides with the time at which MI onset occurs, suggesting prolonged autonomic fluctuation may be a factor in the MI incidence after CEA.  相似文献

Background

Blood-brain barrier (BBB) disruption plays a key role in the pathophysiology of acute ischemic stroke. Matrix metalloproteinases-2/9 (MMP-2/9) have been shown to participate in the disruption of the BBB and hemorrhagic transformation after cerebral ischemia. Toll-like receptor 2 (TLR2) may also be correlated with endothelial cell injury during ischemia-reperfusion events. However, the correlation between MMP-2/9 and TLR2 on endothelial cells after ischemia has not yet been evaluated. The aim of the study was to evaluate the impact of TLR2 and MMP-2/9 on tight junction proteins (TJs) after oxygen–glucose deprivation and reoxygenation (OGDR).

Materials and methods

Rat primary brain microvascular endothelial cells (BMECs) were cultured. Quantitative real-time PCR and western blotting were used to measure the mRNA and proteins expression of TLR2 and MMP-2/-9. The protein expression of TJs was detected by western blotting and immunofluorescence.

Results

MMP-9 significantly increased after OGDR. Protein and mRNA expression of TLR2 was also upregulated. However, claudin-5, occludin, collagen-Ⅳ, and ZO-1 were decreased after OGDR. When monoclonal anti-TLR2 antibody (T2.5) was added to BMECs after OGDR, MMP-9 was significantly downregulated, whereas occludin and collagen-Ⅳ had a tendency to increase.

Conclusion

TLR2 antagonist T2.5 is able to downregulate the expression of MMP-9, and may constitute a therapeutic option for restoration of the BBB after OGDR.  相似文献

Background

The quality of care and outcomes for people who experience stroke whilst in hospital for another condition has not been previously studied in Australia.

Aims

To explore differences in long-term outcomes among patients with in-hospital events treated in stroke units (SUs) compared to those managed in other hospital wards.

Methods

Forty-five hospitals participating in the Australian Stroke Clinical Registry between January 2010 and December 2014 contributed data. Survival of all patients with in-hospital stroke to 180 days after stroke and health-related quality of life, using EQ-5D-3L among 73% eligible, were compared using multilevel, multivariable regression models. Models were adjusted for age, sex, index of relative socioeconomic disadvantage, ability to walk, stroke type, transfer from another hospital, and history of stroke.

Results

Among 20,786 stroke events, 1182 (5.1%) occurred in-hospital (median age 77 years, 49% male). Patients with in-hospital stroke treated in SUs died less often within 30 days (Hazard Ratio 0.56; 95% CI 0.39-0.81) than those not admitted to SUs. Survivors reported similar health-related quality of life between 90 and 180 days compared to those treated in other wards (coefficient?=?0.01, 95% CI –0.06-0.09, P?=?.78). Patients managed in SUs more often received recommended management (e.g. swallowing screening).

Conclusion

The benefits of SU care may extend to patients experiencing in-hospital stroke. Validation, including accounting for potential residual confounding factors, is required.  相似文献

Objective

To determine predictors of direct enteral tube (DET) placement after acute stroke.

Methods

We used the Ontario Stroke Registry to identify patients who received direct enteral tubes (gastrostomy or jejunostomy) during hospital stay after acute ischemic stroke or intracerebral hemorrhage from July 1, 2003 to March 31, 2013. We used multivariable logistic regression to identify predictors of receiving DET after stroke.

Results

Among 38,192 patients with acute stroke who met inclusion criteria, 1851 (4.9%) had DET placement during admission. We identified multiple variables significantly associated with DET placement, spanning patient demographics, comorbid illnesses, clinical, and hospital factors. The strongest predictors of receiving DET were stroke severity (adjusted odds ratio [aOR] 4.77 for severe versus mild stroke, 95% confidence interval [CI] 4.20-5.41), receiving a swallowing test within 72 hours (aOR 3.46, 95% CI 3.0-3.99), and in-hospital stroke (aOR 2.07, 95% CI 1.57-2.72).

Conclusions

There are a number of predictors of DET placement within multiple domains. These findings may facilitate discussions around the possibility of requiring DET during admission. Further work is required to improve patient selection and timing of DET placement after acute stroke.  相似文献

Objective

No studies have estimated the difference in suicidal ideation, plans, and attempts for lesbian, gay, or bisexual (LGB) adults aged 50+ compared with heterosexuals using nationally representative data.

Methods

We used 2015–2017 National Survey on Drug Use and Health data to estimate the prevalence of self-reported suicidal ideation, plans, and attempts for LGB adults 50+ compared with heterosexuals in the preceding 12 months.

Results

Over 185,000 LGB adults aged 50+ in the United States were estimated to have had suicidal ideation in the preceding year. After adjusting for sex and race/ethnicity, LGB individuals aged 50+ had a 4.5 percentage point higher prevalence of suicidal ideation compared with heterosexuals (prevalence difference [PD]: 0.045; 95% confidence interval [CI]: 0.022, 0.067). Of those with suicidal ideation, LGB individuals aged 50+ had a 17.2 percentage point higher prevalence of suicide plans compared with heterosexuals (PD: 0.172; 95% CI: 0.011, 0.332).

Conclusion

LGB adults in middle and older age have higher suicidal ideation and plans than heterosexual peers.  相似文献

Background

Mutation of protein S K196E (PS K196E) is a genetic risk factor for venous thromboembolism; however, there are few reports on cerebral venous thrombosis (CVT) with this mutation. We report a case of CVT that was diagnosed as having PS K196E mutation at the initial thrombotic event.

Methods

A 54-year-old man suddenly developed generalized seizures after headache and nausea. Brain magnetic resonance imaging showed cerebral edema, and angiography revealed CVT. Blood examination revealed that protein S activity was low (44%) despite normal free protein S antigen levels (81%). Sequence analysis revealed a heterozygous PS K196E mutation. We treated him with warfarin with the international normalized ratio maintained at 2.0-3.0. After 1 month, he was discharged without any neurological sequelae.

Results

Early identification of the causes of thrombophilia is important for the long-term management of CVT. However, detection of PS K196E mutation is difficult because its only feature is a moderate decrease in the activity of protein S, which is influenced by environmental factors.

Conclusions

The possibility of PS K196E mutation should be considered if other causes of CVT are ruled out and if protein S activity is decreased.  相似文献

Background

Stevioside, isolated from the herb Stevia rebaudiana, has been widely used as a food sweetener all over the world. Isosteviol Sodium (STV-Na), an injectable formulation of isosteviol sodium salt, has been proved to possess much greater solubility and bioavailability and exhibit protective effects against cerebral ischemia injury in vivo by inhibiting neuron apoptosis. However, the underlying mechanisms of the neuroprotective effects STV-Na are still not completely known. In the present study, we investigated the effects of STV-Na on neuronal cell death caused by hypoxia in vitro and its underlying mechanisms.

Methods

We used cobalt chloride (CoCl2) to expose mouse neuroblastoma N2a cells to hypoxic conditions in vitro.

Results

Our results showed that pretreatment with STV-Na (20 μM) significantly attenuated the decrease of cell viability, lactate dehydrogenase release and cell apoptosis under conditions of CoCl2-induced hypoxia. Meanwhile, STV-Na pretreatment significantly attenuated the upregulation of intracellular Ca2+ concentration and reactive oxygen species production, and inhibited mitochondrial depolarization in N2a cells under conditions of CoCl2-induced hypoxia. Furthermore, STV-Na pretreatment significantly downregulated expressions of nitric oxide synthase, interleukin-1β, tumor necrosis factor-α, interleukin-6, nuclear factor kappa B (NF-κB), and mitogen-activated protein kinase (MAPK) signalings in N2a cells under conditions of CoCl2-induced hypoxia.

Conclusions

Taken together, STV-Na protects neural cells against hypoxia-induced apoptosis through inhibiting MAPK and NF-κB pathways.  相似文献

Background

Stroke burden is extremely high in Chinese hypertensive population. Novel biomarkers for cardiovascular diseases can be detected by metabolomic profiling of human fluids. We aim to find a panel of distinctive plasma metabolites for predicting incident ischemic stroke in hypertensive patients.

Methods

This is a nested case-control study from a prospective cohort design. Baseline plasma samples were collected from 66 newly developed ischemic stroke cases and 66 matched controls. Untargeted metabolomics was performed by ultra-high performance liquid chromatography-tandem mass spectrometry, and data were analyzed by multivariate and univariate statistics.

Results

Plasma metabolite profiles clearly differed between hypertensive patients with incident ischemic stroke and without. A total of 12 metabolites were screened and identified as potential biomarkers. The altered metabolic pathways included retinol metabolism, sphingolipid metabolism, glycerophospholipid metabolism, lysine degradation, tyrosine metabolism, and tryptophan metabolism. For prediction of hypertensive ischemic stroke, the panel of specific metabolomics-based biomarkers provided area under the curve of 0.848 (95% confidence interval: 0.783-0.913).

Conclusions

Our study identified a metabolic signature of incident ischemic stroke in hypertension. Differences in small-molecule metabolites hold translational value in prediction and provide insights into potential new mechanisms of this condition.  相似文献

Background

We evaluated 3-month neurologic, functional, cognitive, and quality of life (QOL) outcomes in intracerebral hemorrhage (ICH) overall, and by sex and ethnicity in a population-based study.

Methods

Spontaneous ICH patients were identified from the Brain Attack Surveillance in Corpus Christi project (November 2008 to December 2013). Outcomes included neurologic (National Institutes of Health Stroke Scale: range 0-42), functional (activities of daily living/instrumental activities of daily living score: range 1-4, higher worse), cognitive (Modified Mini-Mental State Examination [3MSE]: range 0-100), and QOL (short-form stroke-specific QOL scale: range 0-5, higher better). Ethnic and sex differences were assessed with Tobit regression adjusted for age, sex, or ethnicity, and presenting Glasgow coma scale.

Results

A total of 245 patients completed baseline interviews, with 103 (42%) dying prior to follow-up, leaving 142 eligible for outcome assessment. Three-month follow-up was completed in 100 (neurologic), 107 (functional), 79 (cognitive), and 83 (QOL) participants. Median age was 66 years (interquartile range 58.0-77.0). Cognitive outcomes were worse in Mexican Americans (MA) compared to non-Hispanic whites (NHW) after multivariable adjustment (MA scoring 13.3 3MSE points lower than NHW [95% confidence interval: 5.8, 20.7; P?=?.0005]). There was no difference by sex or ethnicity in neurological, functional, or QOL outcomes, and no sex differences in cognitive outcomes.

Conclusions

In this population-based study, worse cognitive outcomes were found in MAs compared with NHW. There were no differences between neurologic, functional, and QOL outcomes in ICH survivors based on sex or ethnicity.  相似文献

Objective

The aim of this study was to identify how a broad range of sociodemographic, military, health, and psychosocial factors relate to accelerated DNA methylation aging (Δage) in a large, contemporary, nationally representative sample of male U.S. veterans.

Methods

Data were analyzed from a sample of U.S. male European-American veterans who participated in the National Health and Resilience in Veterans Study (N?=?1,135).

Results

Psychosocial factors of lifetime trauma burden, child sexual trauma, and negative beliefs about aging were independently associated with Δage. Three health variables—diabetes, hypertension, and body mass index—emerged as additional correlates of Δage.

Conclusion

Results of the study build on prior work demonstrating associations between accelerated DNA methylation aging and traumatic stress, highlighting a role for child sexual abuse in particular. They further underscore the importance of targeting negative beliefs about aging, which are modifiable, in prevention efforts designed to forestall accelerated DNA methylation aging.  相似文献

Objective

Major depressive disorder (MDD) is a prevalent condition in older adults. Although antidepressant drugs are commonly prescribed, efficacy is variable, and older patients are more prone to side effects. Repetitive transcranial magnetic stimulation (rTMS) is an alternative therapy used increasingly in the treatment of MDD. Even though recent studies have shown efficacy of rTMS in elderly depressed patients, the safety and efficacy of accelerated rTMS has not been studied in this population.

Methods

Data were retrospectively analyzed for adults with treatment-resistant depression (N?=?73, n?=?19 ≥60years, n?=?54 <60 years) who underwent an accelerated protocol of 30 sessions (2 sessions per day) of left dorsolateral prefrontal cortex high-frequency (20 Hz) rTMS.

Results

There were statistically significant improvements in depression and anxiety symptoms from baseline to post-treatment in both age groups, but those 60years and older showed statistically greater improvement in depression and anxiety symptom scores (p?=?0.01) than those less than 60. There were significantly more responders (p?=?0.001) and remitters (p?=?0.023) in the older group. The age groups did not differ significantly in clinical and demographic characteristics or severity of current depressive episode, although baseline anxiety was less severe in those 60years and older. Unipolar and bipolar patients had a similar clinical response, and treatment appeared to be well tolerated by all patients.

Conclusion

Our results suggest that accelerated rTMS protocol is a safe and effective treatment for unipolar and bipolar depressed subjects, including older adults.  相似文献

Background

Anton's syndrome is a rare neurological disorder characterized by a combination of visual anosognosia and confabulation of visual experience, most often seen after bilateral ischemic damage to the posterior occipital cortex.

Case report

We report the first case of an acute synchronous P2 occlusion as confirmed by multiparametric computed tomography (CT) including perfusion. After the administration of Recombinant tissue plasminogen activator (rtPA), Anton's syndrome completely resolved.

Conclusion

Multiparametric CT imaging may aid in quickly proving the underlying stroke in Anton's syndrome, especially helpful considering the discrepancy between the patient's perception and clinical examination results.  相似文献

Background

Cerebrovascular stroke is a common critical complication of sickle cell disease (SCD). Angiotensinogen (AGT) M235T gene polymorphism is associated with risk of ischemic stroke and cardiovascular disease.

Aim

We investigated the potential association between angiotensinogen M235T gene polymorphism and susceptibility to cerebrovascular and cardiopulmonary complications in adolescents with SCD.

Methods

Forty-six patients with SCD in steady state were studied stressing on history of stroke, hydroxyurea/chelation therapy, hematological profile, and echocardiographic findings. Polymerase chain reaction-based restriction fragment length polymorphism analysis was used to detect AGT M235T gene polymorphism. Fifty sex- and age-matched healthy controls were enrolled for assessment of M235T gene polymorphism pattern.

Results

The distribution of AGT M235T gene polymorphism was similar between SCD patients and healthy controls. The frequency of T allele of AGT M235T gene polymorphism (TT and MT genotypes) was significantly higher among patients with history of manifest stroke (P < .001). Patients with TT and MT genotypes had higher incidence of cardiopulmonary complications (P?=?.041) as well as higher percentage of HbS (P < .001) and lower hemoglobin level (P?=?.008) compared with those with MM genotype. Serum ferritin, liver iron concentration, and cardiac T2* were not related to T alleles or genotypes. Logistic regression analysis revealed that M235T genotype was a significant independent factor related to the occurrence of stroke among patients with SCD (Odds Ratio 14.05, 95% confidence interval 3.82-28.91; P?=?.001).

Conclusion

AGT M235T gene polymorphism may represent a genetic modifier to vascular morbidities in Egyptian patients with SCD.  相似文献

Background

Percutaneous closure of patent foramen ovale (PFO) is an alternative option to medical treatment for secondary prevention for cryptogenic stroke (CS). Despite technical success of procedure, residual shunt (RS) which is a presumable cause for recurrent stroke is observed in some patients. We evaluated the RS with serial follow-up bubble contrast transesophageal echocardiography (BCTEE) after PFO closure.

Methods

Among consecutive 47 CS patients who underwent PFO closure, a serial follow-up BCTEE at 3 and 9 months after the index procedure was completed in 38 patients (81%, 46 ± 10 years, 19 men). To evaluate the efficacy of PFO closure, the incidence of any and significant RS (≥ moderate) was assessed.

Results

All PFO closure procedures were successful. The Amplatzer PFO Occluder (n?=?19) or the Gore Septal Occluder (n?=?19) were used. Any RS was observed in 13 (34%) and 10 patients (26%) at 3 and 9 months after the procedure. Significant RS was observed in 6 (16%) and 4 (11%) patients at 3- and 9-month follow-up BCTEE. Patients who were treated with the Gore Septal Occluder have a less incidence of any RS in 3 months, and any/significant RS in 3- and 9-month follow-up BCTEE without statistical significance.

Conclusions

RS grade keeps decreasing after PFO closure, but it remains even after 9 months in some patients. Incomplete sealing of PFO should be taken into consideration in management of CS patients even after technically successful PFO closure.  相似文献
