The Outcomes of Spontaneous Intracerebral Hemorrhage in Young Adults - A Clinical Study

Objective Spontaneous intracerebral hemorrhage (ICH) in young adults is rare. The purpose of this study was to investigate causes, sites and other factors affecting the prognosis of ICH in young adults aged ≤ 40 years. Methods We reviewed 39 consecutive patients diagnosed with spontaneous ICH between January 2001 and June 2012. Patients with primary subarachnoid hemorrhage, previously diagnosed brain tumor bleeding, or vascular malformation were excluded. We analyzed the differences in prognostic factors such as hemorrhage location and vascular structural etiology. The outcome was measured using the Glasgow outcome scale (GOS), and a good outcome was defined as a score of 4 or more. Results We retrospectively evaluated 39 patients (mean age, 33 years; SD = 6.4, range 17 to 40 years). The most common structural etiology was arteriovenous malformation. A statistically significantly higher proportion of patients with good outcomes had a lower initial systolic blood pressure (SBP ≤ 160 mmHg, p = 0.036), a higher initial Glasgow coma scale (GCS) (9 or more, p = 0.034), lower cholesterol levels (< 200 mg/dl, p = 0.036), and smoking history (at discharge, p = 0.008; 6 months after discharge, p = 0.019). Conclusion In this study, cryptogenic ICH was the leading cause of spontaneous ICH. A GCS score of 9 or more on admission, a lower serum cholesterol level (< 200 mg/dl), and a lower SBP (< 160 mmHg) predicted a good outcome.
Distributed under Creative Commons Cc-by 4.0 the Ontogenetic Transformation of the Mesosaurid Tarsus: a Contribution to the Origin of the Primitive Amniotic Astragalus

The hypotheses about the origin of the primitive amniotic tarsus are very speculative. Early studies argued that the origin of the astragalus, one of the largest proximal bones in the tarsus of basal amniotes, was produced by either the fusion of two, three, or even four of the original tarsal bones, the intermedium, the tibiale and the proximal centralia (c4 and c3), or that the intermedium alone transforms into the primitive astragalus. More recent studies have shown that the structure of the tarsus in Captorhinus supports the former hypothesis about a fusion of the intermedium, the tibiale, the proximal centrale (c4) and eventually c3, producing a purportedly multipartite structure of the amniotic astragalus, but the issue remained contentious. Very well preserved tarsi of the Early Permian aquatic amniote Mesosaurus tenuidens Gervais, 1864–1865, which represent the most complete ontogenetic succession known for a basal amniote (the other exceptional one is provided by the Late Permian diapsid Hovasaurus boulei Piveteau, 1926), suggest that there is more than one ossification center for the astragalus and that these fuse during late embryonic stages or maybe early after birth. A non-hatched Mesosaurus in an advanced stage of development shows that the tarsus is represented by a single bone, most probably the astragalus, which seems to be formed by the suturing of three bones, here interpreted as being the intermedium, the tibiale, probably already integrated to the c4 in an earlier stage of the development, and the c3. An amniote-like tarsal structure is observed in very basal Carboniferous and Permian tetrapods such as Proterogyrinus, Gephyrostegus, the diadectids Diadectes and Orobates, some microsaurs like Tuditanus and Pantylus and possibly Westlothiana, taxa that were all considered as true amniotes in their original descriptions. Therefore, the structure of the amniotic tarsus, including the configuration of the proximal series formed by the astragalus and the calcaneum, typically a pair of enlarged bones, could have been established well before the first recognized amniote walked on Earth. Accordingly, the tarsus of these taxa does not constitute specialized convergences that appeared in unrelated groups, they might be instead, part of a transformation series that involves taxa closely related to the early amniotes as some hypotheses have suggested.

Migraine prevention

Preventive medications reduce migraine frequency and severity, and improve migraine-specific quality of life. Recent evidence also suggests that these same medications enhance the patient’s response to acute migraine therapies, and may also reduce the likelihood of developing chronic daily headache. However, many patients who should receive or be offered preventive treatment are not. Most patients can be successfully managed when patient and physician expectations are realistic and aligned, the selection of preventive medications is individualised, and the initiation and titration strategy is appropriate and carefully followed. Rational combinations of preventive medications may also be useful. This review provides an evidence and experience-based approach to the preventive treatment of migraine.
Intestinal Cgi-58 Deficiency Reduces Postprandial Lipid Absorption

Comparative Gene Identification-58 (CGI-58), a lipid droplet (LD)-associated protein, promotes intracellular triglyceride (TG) hydrolysis in vitro. Mutations in human CGI-58 cause TG accumulation in numerous tissues including intestine. Enterocytes are thought not to store TG-rich LDs, but a fatty meal does induce temporary cytosolic accumulation of LDs. Accumulated LDs are eventually cleared out, implying existence of TG hydrolytic machinery in enterocytes. However, identities of proteins responsible for LD-TG hydrolysis remain unknown. Here we report that intestine-specific inactivation of CGI-58 in mice significantly reduces postprandial plasma TG concentrations and intestinal TG hydrolase activity, which is associated with a 4-fold increase in intestinal TG content and large cytosolic LD accumulation in absorptive enterocytes during the fasting state. Intestine-specific CGI-58 knockout mice also display mild yet significant decreases in intestinal fatty acid absorption and oxidation. Surprisingly, inactivation of CGI-58 in intestine significantly raises plasma and intestinal cholesterol, and reduces hepatic cholesterol, without altering intestinal cholesterol absorption and fecal neutral sterol excretion. In conclusion, intestinal CGI-58 is required for efficient postprandial lipoprotein-TG secretion and for maintaining hepatic and plasma lipid homeostasis. Our animal model will serve as a valuable tool to further define how intestinal fat metabolism influences the pathogenesis of metabolic disorders, such as obesity and type 2 diabetes.
Dietary Pattern Is Associated with Obesity in Older People in China: Data from China Health and Nutrition Survey (CHNS)

Background: No studies have been conducted to explore the associations between dietary patterns and obesity among older Chinese people, by considering gender and urbanization level differences. Methods: We analyzed data from the 2009 China Health and Nutrition Survey (2745 individuals, aged ≥ 60 years). Dietary data were obtained using 24 h-recall over three consecutive days. Height, Body Weight, and Waist Circumference were measured. Exploratory factor analysis was used to identify dietary patterns. Multinomial and Poisson regression models were used to examine the association between dietary patterns and Body Mass Index (BMI) status/central obesity. Results: The prevalence of general and central obesity was 9.5% and 53.4%. Traditional dietary pattern (high intake of rice, pork and vegetables) was inversely associated with general/central obesity; modern dietary pattern (high intake of fruit, fast food, and processed meat) was positively associated with general/central obesity. The highest quartile of traditional dietary pattern had a lower risk of general/central obesity compared with the lowest quartile, while an inverse picture was found for the modern dietary pattern. These associations were consistent by gender and urbanization levels. Conclusions: Dietary patterns are associated with general/central obesity in older Chinese. This study reinforces the importance of a healthy diet in promoting healthy ageing in China.
An Automatic Device for the Measurement of the Growth of Water Trees

An automatic device for the measurement of the growth of water trees as a function of time is described. The system is based on video camera signal processing of the images of water trees through a microscope. Water trees are grown in laboratory specimens using the water needle method. At regular intervals, specimens under test are successively placed under the microscope and any change in light transmission along the axis of the water tree is detected and stored in a memory device. Several examples of results obtained with the device are presented. Due to its high sensitivity it allows new observations such as, for example, residual growth of water trees after the voltage switched off. The device allows study of the growth mechanisms of water trees as well as comparisons of the resistance of translucent materials to water treeing.
The process of change in brief psychotherapy: Effects of psychodynamic and cognitive–behavioral prototypes

Abstract A brief psychodynamic psychotherapy was assessed using the Brazilian Portuguese version of the Psychotherapy Process Q-Set (PQS). Each session was scored for its adherence to expert psychodynamic therapy (PDT) and cognitive–behavioral therapy (CBT) prototypes derived from the PQS. Results revealed that the therapy process adhered more closely to prototypical CBT than prototypical PDT. Bivariate time-series analyses showed that prototype components capturing the client's adherence to ideal CBT behaviors and collaboration between therapist and client on ideal PDT and CBT behaviors predicted therapy progress. In addition, specific client symptoms influenced whether the therapist adhered to prototypical PDT or CBT behaviors.
Progression in Parkinson's disease: A positron emission tomography study with a dopamine transporter ligand [18F]CFT

We studied the rate of progression of striatal dopamine transporter function in Parkinson's disease (PD). Eight patients with early PD without antiparkinsonian medication and 7 healthy volunteers were investigated with [18F]CFT positron emission tomography (PET). The PET scan was carried out twice at an approximate 2‐year interval. The uptake of [18F]CFT was calculated as a region‐cerebellum:cerebellum ratio at 180 to 210 minutes after injection. At the first PET scan, the [18F]CFT uptake in PD patients in the putamen was 1.45 ± 0.45 (mean ± SD) (42% of the control mean) and 2.43 ± 0.59 in the caudate nucleus (76% of the control mean). The ratios declined by the time of the second PET scan, and the rate of annual decline of the baseline mean in PD patients was 13.1% in the putamen and 12.5% in the caudate nucleus. In controls, the corresponding figures were 2.1% for the putamen and 2.9% for the caudate nucleus. The decline in [18F]CFT uptake was significantly higher in PD patients than in controls. Thus, dopamine transporter ligands such as [18F]CFT seem to be sensitive markers for the rate of progression in PD. Ann Neurol 2000;47:804–808
Glial Cells Decipher Synaptic Competition at the Mammalian Neuromuscular Junction

It is now accepted that glial cells actively interact with neurons and modulate their activity in many regions of the nervous system. Importantly, modulation of synaptic activity by glial cells depends on the proper detection and decoding of synaptic activity. However, it remains unknown whether glial cells are capable of decoding synaptic activity and properties during early postdevelopmental stages, in particular when different presynaptic nerve terminals compete for the control of the same synaptic site. This may be particularly relevant because a major determinant of the outcome of synaptic competition process is the relative synaptic strength of competing terminals whereby stronger terminals are more likely to occupy postsynaptic territory and become stabilized while weaker terminals are often eliminated. Hence, because of their ability to decode synaptic activity, glial cells should be able to integrate neuronal information of competing terminals. Using simultaneous glial Ca2+ imaging and synaptic recordings of dually innervated mouse neuromuscular junctions, we report that single glial cells decipher the strength of competing nerve terminals. Activity of single glial cells, revealed by Ca2+ responses, reflects the synaptic strength of each competing nerve terminal and the state of synaptic competition. This deciphering is mediated by functionally segregated purinergic receptors and intrinsic properties of glial cells. Our results indicate that glial cells decode ongoing synaptic competition and, hence, are poised to influence its outcome.
Evaluating the Impact of AbuseHUB on Botnet Mitigation

This documents presents the final report of a two-year project to evaluate the impact of AbuseHUB, a Dutch clearinghouse for acquiring and processing abuse data on infected machines. The report was commissioned by the Netherlands Ministry of Economic Affairs, a co-funder of the development of AbuseHUB. AbuseHUB is the initiative of 9 Internet Service Providers, SIDN (the registry for the .nl top-level domain) and Surfnet (the national research and education network operator). The key objective of AbuseHUB is to improve the mitigation of botnets by its members. We set out to assess whether this objective is being reached by analyzing malware infection levels in the networks of AbuseHUB members and comparing them to those of other Internet Service Providers (ISPs). Since AbuseHUB members together comprise over 90 percent of the broadband market in the Netherlands, it also makes sense to compare how the country as a whole has performed compared to other countries. This report complements the baseline measurement report produced in December 2013 and the interim report from March 2015. We are using the same data sources as in the interim report, which is an expanded set compared to the earlier baseline report and to our 2011 study into botnet mitigation in the Netherlands.
Effect of infant formula on stool characteristics of young infants.

BACKGROUND Many infants are switched between multiple formula preparations early in life because of perceived abnormalities in stooling pattern as well as gastrointestinal symptoms. OBJECTIVE To investigate the relationship between the type of formula consumed and the stooling characteristics and gastrointestinal symptoms of young infants. METHODS Healthy 1-month-old infants were fed one of four commercial formula preparations (Enfamil, Enfamil with Iron, ProSobee, and Nutramigen) for 12 to 14 days in a prospective double-blinded (parent/physician) fashion. Parents completed a daily diary of stool characteristics as well as severity of spitting, gas, and crying for the last 7 days of the study period. A breast-fed infant group was studied as well. RESULTS Two hundred eighty five infants were enrolled and 238 completed the study. Infants receiving breast milk or Nutramigen had twice as many stools as other formula groups (P < .001). Infants receiving ProSobee had hard/firm stools more often than breast-fed or other formula-fed groups (P < .00001). Watery stools were more common in infants fed Nutramigen than other formula groups (P < .04). Green stools were more common in 12 mg/L iron preparations (Enfamil with iron, ProSobee, Nutramigen) than in those with 1 mg/L (Enfamil, breast milk) (P < .00001). Spitting, gassiness, and crying were of equal severity in all formula groups. CONCLUSIONS The interpretation of stool frequency, color, and consistency must take into account the infant's formula type as significant variations in normal infants occur. Parental education on the range of infant stooling characteristics as well as the common occurrence of spitting, gas, and crying may alleviate concern for formula intolerance and underlying gastrointestinal disease.
Neural Basis of Endogenous and Exogenous Spatial Orienting: A Functional MRI Study

Whole-brain functional magnetic resonance imaging (MRI) was used to examine the neural substrates of internally (endogenous) and externally (exogenous) induced covert shifts of attention. Thirteen normal subjects performed three orienting conditions: endogenous (location of peripheral target predicted by a central arrow 80 of the time), exogenous (peripheral target preceded by a noninformative peripheral cue), and control (peripheral target preceded by noninformative central cue). Behavioral results indicated faster reaction times (RTs) for valid than for invalid trials for the endogenous condition but slower RTs for valid than for invalid trials for the exogenous condition (inhibition of return). The spatial extent and intensity of activation was greatest for the endogenous condition, consistent with the hypothesis that endogenous orienting is more effortful (less automatic) than exogenous orienting. Overall, we did not observe distinctly separable neural systems associated with the endogenous and exogenous orienting conditions. Both exogenous and endogenous orienting, but not the control condition, activated bilateral parietal and dorsal premotor regions, including the frontal eye fields. These results suggest a specific role for these regions in preparatory responding to peripheral stimuli. The right dorsolateral prefrontal cortex (BA 46) was activated selectively by the endogenous condition. This finding suggests that voluntary, but not reflexive, shifts of attention engage working memory systems.
Number of Tracts or Stone Size: Which Influences Outcome of Percutaneous Nephrolithotomy for Staghorn Renal Stones?

Introduction: Percutaneous nephrolithotomy (PCNL) is the recommended first-line treatment for staghorn stones. To achieve complete stone clearance, PCNL may require using multiple tracts. Objective: To evaluate outcome of PCNL in patients with staghorn calculi and its correlation with the number of tracts and stone features. Materials and Methods: One hundred consecutive patients with staghorn renal stone who underwent PCNL were included in the study. Perioperative and postoperative features were recorded. Correlation of the variables with number of tracts and stone size was assessed. Results: Mean age (±SD) was 49.6 ± 14.7 years. Our patients were ASA class I. The mean cumulative stone burden was 365.9 ± 156.5 mm2. The mean number of tracts was 2.4 (range: 1–7), and stone-free rate was 83%. The stone-free rate (p = 0.026) and hospital stay (p = 0.005) correlated with stone size, but not with number of tracts. Postoperative fever correlated with stone size (p = 0.017) and number of tracts (p = 0.037). Conclusion: PCNL using multiple tracts seem to be effective and safe in treatment of staghorn calculi. Most outcome measures correlated with stone size rather than number of tracts.
Poliovirus concentration from tap water with electropositive adsorbent filters

Simple, reliable, and efficient concentration of poliovirus from tap water was obtained with two types of electropositive filter media, one of which is available in the form of a pleated cartridge filter (Virozorb 1MDS). Virus adsorption from tap water between pH 3.5 and 7.5 was more efficient with electropositive filters than with Filterite filters. Elution of adsorbed viruses was more efficient with beef extract in glycine, pH 9.5, than with glycine-NaOH, pH 11.0. In paired comparative studies, electropositive filters, with adsorption at pH 7.5 and no added polyvalent cation salts, gave less variable virus concentration efficiencies than did Filterite filters with adsorption at pH 3.5 plus added MgCl2. Recovery of poliovirus from 1,000-liter tap water volumes was approximately 30% efficient with both Virozorb 1MDS and Filterite pleated cartridge filters, but the former were much simpler to use. The virus adsorption behavior of these filters appears to be related to their surface charge properties, with more electropositive filters giving more efficient virus adsorption from tap water at higher pH levels.
The Locus of Enterocyte Effacement-Encoded Effector Proteins All Promote Enterohemorrhagic Escherichia coli Pathogenicity in Infant Rabbits

ABSTRACT The genes encoding the enterohemorrhagic Escherichia coli (EHEC) type III secretion system (TTSS) and five effector proteins secreted by the TTSS are located on the locus of enterocyte effacement (LEE) pathogenicity island. Deletion of tir, which encodes one of these effector proteins, results in a profound reduction (∼10,000-fold) in EHEC colonization of the infant rabbit intestine, but the in vivo phenotypes of other LEE genes are unknown. Here, we constructed in-frame deletions in escN, the putative ATPase component of the TTSS, and the genes encoding the four other LEE-encoded effector proteins, EspH, Map, EspF, and EspG, to investigate the contributions of the TTSS and the translocated effector proteins to EHEC pathogenicity in infant rabbits. We found that the TTSS is required for EHEC colonization and attaching and effacing (A/E) lesion formation in the rabbit intestine. Deletion of escN reduced EHEC recovery from the rabbit intestine by ∼10,000-fold. Although EspH, Map, EspF, and EspG were not required for A/E lesion formation in the rabbit intestine or in HeLa cells, these effector proteins promote EHEC colonization. Colonization by the espH and espF mutants was reduced throughout the intestine. In contrast, colonization by the map and espG mutants was reduced only in the small intestine, indicating that Map and EspG have organ-specific effects. EspF appears to down-regulate the host response to EHEC, since we observed increased accumulation of polymorphonuclear leukocytes in the colonic mucosa of rabbits infected with the EHEC espF mutant. Thus, all the known LEE-encoded effector proteins influence EHEC pathogenicity.
Effect of Variable and Constant-Frequency Train in Latissimus Dorsi Muscle Stimulation

We tested the hypothesis that increased hemodynamic augmentation and mechanical performance could be achieved by using a variable frequency pulse train (VFT) to stimulate the latissimus dorsi muscle (LDM), compared to the conventional constant frequency pulse train (CFT) used in cardiomyoplasty. In dogs (n = 6), a vascular delayed LDM was wrapped posteriorly around the heart. LDM was conditioned for 9 weeks using implantable cardiomyostimulator. The hemodynamic parameters were recorded using VFT and CFT LDM stimulation with 7, 6 and 5-pulses, and compared to non-stimulated beats (NS). Both CFT and VFT LDM stimulation significantly increased pressures, flow, and stroke work. However, compared to CFT, VFT stimulation resulted in significant stroke power (20.6%), maximum peak aortic flow (20.1%) and maximum LV dP/dt (14.6%). These results suggested that stimulation of the LDM using VFTs is potentially greater beneficiary for application in cardiomyoplasty.
