Hybrid laparoscopic ureteral reimplantation for the treatment of primary vesicoureteral reflux and obstructive megaureter.

Laparoscopic ureteral reimplantation has gained increasing popularity in treating pediatric primary vesicoureteral reflux (VUR) and obstructive megaureter (OM). However, it is technically challenging with a relatively low success rate compared to open surgery. Here we designed a hybrid technique which incorporates laparoscopic surgery and pneumovesical ureteral reimplantation.

Transumbilical single-incision hybrid pyeloplasty for infant ureteropelvic junction obstruction.

Ureteropelvic junction obstruction (UPJO) can be treated by various pyeloplasty techniques. We present a hybrid technique incorporating elements of laparoendoscopic single-site surgery and open pyeloplasty through a single umbilical incision. As a result, seven infants with UPJO underwent the hybrid pyeloplasty smoothly.

Involvement of single nucleotide polymorphisms of junction adhesion molecule with small vessel vascular dementia.

Objectives: It is now recognized that blood brain barrier (BBB) leakage occurs in cerebral small vascular disease (CSVD) and plays a significant role in the pathophysiology of vascular dementia. We hypothesized that genetic polymorphisms of junctional adhesion molecule-A (JAM-A) (which may result in compromised structure of tight junction proteins that form the BBB) in combination with cerebrovascular risk factors hypertension, lipid disorders, and type 2 diabetes may result in BBB leakage and increase the individual's risk of CSVD-related dementia.

Methods: In this case-control study, 97 controls with a mean Mini-Mental State Exam (MMSE) score of 29 and 38 CSVD-related vascular dementia participants (mean MMSE score of 19) were recruited.

The association between dietary patterns, plasma lipid profiles, and inflammatory potential in a vascular dementia cohort.

Background: Inflammation and altered lipid dyshomeostasis have been implicated in the pathogenesis of Alzheimer's disease and vascular dementia.

Objective: To determine if there are any associations between dietary patterns, plasma lipid profiles, and inflammatory potential in a vascular dementia cohort.

Methods: One hundred fifty participants (36 subjects with Vascular Dementia and 114 healthy controls) from two Australian teaching hospitals completed a cross-sectional survey examining their dietary and lifestyle patterns.

Plasma biomarkers inclusive of α-synuclein/amyloid-beta40 ratio strongly correlate with Mini-Mental State Examination score in Parkinson's disease and predict cognitive impairment.

Plasma biomarkers for Parkinson's disease (PD) diagnosis that carry predictive value for cognitive impairment are valuable. We explored the relationship of Mini-Mental State Examination (MMSE) score with plasma biomarkers in PD patients and compared results to vascular dementia (VaD) and normal controls. The predictive accuracy of an individual biomarker on cognitive impairment was evaluated using area under the receiver operating characteristic curve (AUROC), and multivariate logistic regression was applied to evaluate predictive accuracy of biomarkers on cognitive impairment; 178 subjects (41 PD, 31 VaD and 106 normal controls) were included.

Characteristics of childhood-onset systemic lupus erythematosus in pregnancy and its association with pregnancy outcomes: a retrospective comparative cohort study.

Background: Disease situations are more aggressive in patients with childhood-onset systemic lupus erythematosus (cSLE) than in those with adult-onset SLE (aSLE). However, information on pregnant women with cSLE and its association with pregnancy outcomes is limited. This study aimed to compare pregnancies in patients with cSLE vs.

Strong Predictive Algorithm of Pathogenesis-Based Biomarkers Improves Parkinson's Disease Diagnosis.

Easily accessible and accurate biomarkers can aid Parkinson's disease diagnosis. We investigated whether combining plasma levels of α-synuclein, anti-α-synuclein, and/or their ratios to amyloid beta-40 correlated with clinical diagnosis. The inclusion of amyloid beta-40 (Aβ40) is novel.

Macrophage- and Microglia-Related Chemokines Are Associated with Small Vessel (White Matter) Vascular Dementia: A Case-Control Study.

Introduction: Little is known about the role of inflammation in the process of small vessel vascular dementia (VaD). Recently, the notion that small vessel VaD is caused solely by vascular pathology has been challenged by new evidence of concomitant breakdown of the blood-brain barrier and dysregulation of neuroinflammation in the white matter.

Methods: We examined selected inflammatory cytokines and chemokines in the plasma from patients with small vessel VaD (n = 41) and from age-matched controls (n = 131) using multiplex bead-based assays.

Development of an Aerobic Glycolysis Index for Predicting the Sorafenib Sensitivity and Prognosis of Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is a deadly tumor with high heterogeneity. Aerobic glycolysis is a common indicator of tumor growth and plays a key role in tumorigenesis. Heterogeneity in distinct metabolic pathways can be used to stratify HCC into clinically relevant subgroups, but these have not yet been well-established.

Plasma lipidomic biomarker analysis reveals distinct lipid changes in vascular dementia.

Vascular dementia (VaD) is a complex neurocognitive disorder secondary to a variety of cerebrovascular lesions. Numerous studies have shown that lipid metabolism is involved in the pathobiology of the disease. We examined the plasma lipid profiles in VaD, with the expectation of identifying reliable lipid biomarkers for VaD.

Re-pigmentation of hair after prolonged cholinesterase inhibitor therapy in a Chinese population.

Eighty consecutive Chinese patients diagnosed with Alzheimer disease were assessed for darkening of grey hair. Of the 62 eligible patients (mean age = 79.3 ± 7.

Mini-review on initiatives to interfere with the propagation and clearance of alpha-synuclein in Parkinson's disease.

In this mini-review, we summarize recent findings relating to the prion-like propagation of α-synuclein (α-syn) and the development of novel therapeutic strategies to target synucleinopathy in Parkinson's disease (PD). We link the Braak's staging hypothesis of PD with the recent evidence from in-vivo and in-vitro studies for the prion-like cell-to-cell propagation of α-syn (via exocytosis and endocytosis). The classical accumulation of aggregated α-syn in PD may result from an increased production or a failure in the mechanisms of clearance of α-syn.

Isoflurane promotes glucose metabolism through up-regulation of and suppresses mitochondrial oxidative phosphorylation in ovarian cancer cells.

Ovarian cancer is one of the most lethal gynecologic malignancies in women. Isoflurane is one of the volatile anesthetics used extensively for inhalational anesthesia and gynecological surgery. However, the effects of isoflurane on ovarian cancer have not been fully elucidated.

Delirium post-stroke: short- to long-term effect on anxiety and depression compared to effect on cognition.

Background Delirium is common after stroke and has significant negative impact on mortality, morbidity, cognitive function, and institutionalization. Despite these known effects, any impact of delirium on the emotional well-being of stroke survivors is unclear. Methods A post hoc analysis was performed on our prospective cohort study of 156 stroke patients.

Association of genetic polymorphisms of claudin-1 with small vessel vascular dementia.

The most recent hypothesis of the development of small vessel vascular dementia (VaD) emphasises the role of blood-brain barrier (BBB) dysfunction. It is hypothesised that certain genetic polymorphisms of the BBB tight junction claudin-1 protein, in combination with adverse environmental risk factors, increase the risk of BBB dysfunction and small vessel VaD. In this case-control study, 97 control participants, with a mean Mini Mental State Exam (MMSE) score of 29.

Interference of α-Synuclein Uptake by Monomeric β-Amyloid1-40 and Potential Core Acting Site of the Interference.

Increasing evidence suggests an important role of alpha-synuclein (α-Syn) in the pathogenesis of Parkinson's disease (PD). The inter-neuronal spread of α-Syn via exocytosis and endocytosis has been proposed as an explanation for the neuropathological findings of PD in sub-clinical and clinical phases. Therefore, interfering the uptake of α-Syn by neurons may be an important step in slowing or modifying the propagation of the disease.

Genetic and environmental factors in vascular dementia: an update of blood brain barrier dysfunction.

Vascular dementia (VaD) describes a combination of both cognitive and behavioural manifestations associated with variable brain lesions of vascular origin. While vascular risk factors have been implicated in VaD, the relationship is most evident when the factors are considered together and not individually. This review will examine the significance of the integrity of blood brain barrier (BBB) tight junction (TJ) proteins - occludin and claudins in the pathophysiology of VaD.

Mortality trend and predictors of mortality in dysphagic stroke patients postpercutaneous endoscopic gastrostomy.

Background: Percutaneous endoscopic gastrostomy (PEG) feeding is widely used in stroke patients suffering from persistent dysphagia; however, predicting the risks and benefits of PEG insertion in the individual patient is difficult. The aim of our study was to investigate if candidate risk factors could predict short-term mortality risk in poststroke patients who had PEG tube insertion for persistent dysphagia.

Methods: This was a retrospective study of 3504 consecutive stroke patients admitted to two metropolitan hospitals during the period January 2005 to December 2013 and who also underwent PEG insertion for feeding due to persistent dysphagia.

Relationship of immunogenicity to protective potency in acellular pertussis vaccines.

Comparison of the immunogenicity response and resistance to challenge in the modified intracerebral challenge assay induced by various acellular pertussis vaccines showed that these were not closely linked. The immunogenicity assay was effective for confirming the presence of specific antigenic components and was invaluable for detecting minor components present in co-purified vaccines. However, the magnitude of antibody responses was not consistently related to antigen concentration nor did it correlate with protection in the modified intracerebral challenge assay.

Health service management study for stroke: a randomized controlled trial to evaluate two models of stroke care.

Background: The most effective and efficient model for providing organized stroke care remains uncertain. This study aimed to compare the effect of two models in a randomized controlled trial.

Methods: Patients with acute stroke were randomized on day one of admission to combined, co-located acute/rehabilitation stroke care or traditionally separated acute/rehabilitation stroke care.

Uptake and mitochondrial dysfunction of alpha-synuclein in human astrocytes, cortical neurons and fibroblasts.

The accumulation and aggregation of alpha-synuclein (α-syn) in several tissue including the brain is a major pathological hallmark in Parkinson's disease (PD). In this study, we show that α-syn can be taken up by primary human cortical neurons, astrocytes and skin-derived fibroblasts in vitro. Our findings that brain and peripheral cells exposed to α-syn can lead to impaired mitochondrial function, leading to cellular degeneration and cell death, provides additional evidence for the involvement of mitochondrial dysfunction as a mechanism of toxicity of α-syn in human cells.

Alpha-synuclein transmission and mitochondrial toxicity in primary human foetal enteric neurons in vitro.

Parkinson's disease (PD) is a multicentred neurodegenerative disorder characterised by the accumulation and aggregation of alpha-synuclein (α-syn) in several parts of the central nervous system. However, it is well established that PD can generate symptoms of constipation and other gastrointestinal problems and α-syn containing lesions have been identified in intestinal nerve cells. In this study, we show that α-syn can be taken up and accumulate in primary human foetal enteric neurons from the gastrointestinal tract and can be transferred between foetal enteric neurons.
