description: Construction and classification of 2D superintegrable systems (i.e. systems admitting, in addition to two global integrals of motion guaranteeing the Liouville integrability, the third global and independent one) defined on 2D spaces of constant curvature and separable in the so called geodesic polar coordinates are presented. The method proposed is applicable to any value of curvature including the case of Euclidean plane, the 2-sphere and the hyperbolic plane. The mathematic used is essentially "physical", in particular it refers to the very elegant technique of action-angle variables and perturbation theory so most of our mathematical formulas have a clear physical meaning. The main result can be considered as a kind of generalization of the Bertrand's theorem on 2D spaces of constant curvature and it covers most of known separable and superintegrable models on such spaces (in particular, the so-called Tremblay-Turbiner-Winternitz (TTW) and Post-Winternitz (PW) models which have recently attracted some interest).

description: The Oregon Health Study was a groundbreaking experiment in which uninsured participants were randomized to either apply for Medicaid or stay with their current care.

The study showed that Medicaid produced numerous important socioeconomic and health benefits but had no statistically significant impact on hypertension, hypercholesterolemia, or diabetes. Medicaid opponents interpreted the findings to mean that Medicaid is not a worthwhile investment. Medicaid proponents viewed the experiment as statistically underpowered and, irrespective of the laboratory values, suggestive that Medicaid is a good investment.

We tested these competing claims and, using a sensitive joint test and statistical power analysis, confirmed that the Oregon Health Study did not improve laboratory values. However, we also found that Medicaid is a good value, with a cost of just $62 000 per quality-adjusted life-years gained.

Leptogenesis and $CP$ violation in $SU(5)$ models with lepton flavor mixing originating from the right-handed sector

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We discuss neutrino masses and mixing in the context of seesaw type I models with three right-handed Majorana neutrinos and an approximately diagonal Dirac sector. This ansatz is motivated by the idea that the flavor structure in the right-handed Majorana masses is responsible for the large mixing angles, whereas the small mixing angle $θ_{13}$ originates from the Dirac Yukawa couplings in analogy to the quark sector. To obtain $θ_{13} \approx 0.15$ we study a possible $SU(5)$ grand unified theory realization with a $U(1) \times \mathbb{Z}'_2 \times \mathbb{Z}''_2 \times \mathbb{Z}'''_2$ flavor symmetry and include a complex perturbation parameter in the Dirac mass matrix. The consequences for $CP$ violating phases and effects on leptogenesis are investigated.

description: Objectives. We used 37 years of follow-up data from a randomized controlled trial to explore the linkage between an early educational intervention and adult health.

Methods. We analyzed data from the High/Scope Perry Preschool Program (PPP), an early school-based intervention in which 123 children were randomized to a prekindergarten education group or a control group. In addition to exploring the effects of the program on health behavioral risk factors and health outcomes, we examined the extent to which educational attainment, income, family environment, and health insurance access mediated the relationship between randomization to PPP and behavioral and health outcomes.

Results. The PPP led to improvements in educational attainment, health insurance, income, and family environment Improvements in these domains, in turn, lead to improvements in an array of behavioral risk factors and health (P = .01). However, despite these reductions in behavioral risk factors, participants did not exhibit any overall improvement in physical health outcomes by the age of 40 years.

Conclusions. Early education reduces health behavioral risk factors by enhancing educational attainment, health insurance coverage, income, and family environments. Further follow-up will be needed to determine the long-term health effects of PPP.

description: We developed an automated pattern recognition code that is particularly well suited to extract one-dimensional curvi-linear features from two-dimensional digital images. A former version of this {\sl Oriented Coronal CUrved Loop Tracing (OCCULT)} code was applied to spacecraft images of magnetic loops in the solar corona, recorded with the NASA spacecraft {\sl Transition Region And Coronal Explorer (TRACE)} in extreme ultra-violet wavelengths. Here we apply an advanced version of this code ({\sl OCCULT-2}) also to similar images from the {\sl Solar Dynamics Observatory (SDO)}, to chromospheric H-$α$ images obtained with the {\sl Swedish Solar Telescope (SST)}, and to microscopy images of microtubule filaments in live cells in biophysics. We provide a full analytical description of the code, optimize the control parameters, and compare the automated tracing with visual/manual methods. The traced structures differ by up to 16 orders of magnitude in size, which demonstrates the universality of the tracing algorithm.

description: Background: Hemichorea–hemiballism (HCHB) is a hyperkinetic movement disorder with features of both chorea and ballism occurring on the same side.

Case report: We present a case of HCHB due to nonketotic hyperglycemia (NKH) that was the initial presentation of diabetes and was irreversible clinically even after 6 months of optimal blood sugar control.

Discussion: Although HCHB due to hyperglycemia is a potentially reversible condition in the majority of patients, prolonged uncontrolled hyperglycemia may cause ischemic insult and persistent symptoms. Hyperglycemia should always be kept in the list of differentials while dealing with patients who are newly diagnosed with HCHB.

description: Background: Cervical dystonia (CD) is a debilitating neurological disorder that may gravely affect a patient’s quality of life (QoL). Botulinum toxin treatment has been approved as a first-line treatment for this condition. This study aims to look at the efficacy and impact on the QoL of neu-botulinumtoxinA, a newer and cheaper botulinum toxin type A, in patients with CD.

Methods: This is a prospective, open-label, single-arm study. CD patients were recruited and evaluated for severity of CD using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS), and for QoL using the Craniocervical Dystonia Questionnaire (CDQ-24), and the 36-item Short Form Health Survey questionnaire (SF-36) at baseline and 6 weeks after injection.

Results: Twenty patients were recruited. Significant improvement was shown in part 1 and total TWSTRS score and total CDQ-24 scores. Analysis of individual items of the TWSTRS scale showed significant improvement in rotation, duration of CD, and work ability. Significant improvements in the QoL were also seen in some items of the stigma, emotional wellbeing, and energy/fatigue domains of the CDQ-24 and SF-36 questionnaires.

Discussion: Neu-botulinumtoxinA is efficacious in treating CD symptoms and improving QoL of patients with CD. A larger, double-blinded study is needed to study the extent of improvements.

description: Background: In the past few decades, much has been learned about the pathophysiology of restless legs syndrome (RLS). Investigators have studied neuropathology, imaging, electrophysiology, and genetics of RLS, identifying brain regions and biological systems affected in RLS. This manuscript will review RLS pathophysiology literature, examining the RLS state through consideration of the neuroanatomy, then the biological, organ, and genetic systems.

Methods: Pubmed (1966 to April 2016) was searched for the term “restless legs syndrome” cross-referenced with “pathophysiology,” “pathogenesis,” “pathology,” or “imaging.” English language papers were reviewed. Studies that focused on RLS in relation to another disease were not reviewed.

Results: Although there are no gross structural brain abnormalities in RLS, widespread brain areas are activated, including the pre- and post-central gyri, cingulate cortex, thalamus, and cerebellum. Pathologically, the most consistent finding is striatal iron deficiency in RLS patients. A host of other biological systems are also altered in RLS, including the dopaminergic, oxygen-sensing, opioid, glutamatergic, and serotonergic systems. Polymorphisms in genes including BTBD9 and MEIS1 are associated with RLS.

Discussion: RLS is a neurologic sensorimotor disorder that involves pathology, most notably iron deficiency, in motor and sensory brain areas. Brain areas not subserving movement or sensation such as the cingulate cortex and cerebellum are also involved. Other biological systems including the dopaminergic, oxygen-sensing, opioid, glutamatergic, and serotonergic systems are involved. Further research is needed to determine which of these anatomic locations or biological systems are affected primarily, and which are affected in a secondary response.

description: Background: Hemichorea/hemiballism associated with nonketotic hyperglycemia is a well-recognized syndrome, but few case series have been reported in the literature.

Case Report: We describe 20 patients with hemichorea/hemiballism associated with hyperglycemia (9 males and 11 females) with mean age of 67.8 years. Ten patients had a previous diagnosis of type 2 diabetes mellitus, and one had type 1 diabetes mellitus. Six of them had documentation of poor diabetic control over at least the last 3 months. Nine patients had new-onset hyperglycemia with a diagnosis of diabetes mellitus made after discharge. Seventeen patients had unilateral chorea/ballism, while three had bilateral chorea/ballism. Eighteen cases had striatal hyperdensities on computed tomography (CT) and/or hyperintense signals on magnetic resonance imaging (MRI). The putamen was affected in all cases, and the caudate nucleus was involved in nine.

Discussion: Hemichorea/hemiballism associated with nonketotic hyperglycemia can be the presenting sign of diabetes mellitus in almost half of cases or can occur after a few months of poor glycemic control in patients with diagnosed diabetes. This case series is one of the largest to date and adds valuable information about clinical and neuroimaging features that are comparable with published data but also emphasize the role of adequate diabetes mellitus control.
A review of the relevance of the 'CLOUD' results and other recent observations to the possible effect of cosmic rays on the terrestrial climate

description: The problem of the contribution of cosmic rays to climate change is a continuing one and one of importance. In principle, at least, the recent results from the CLOUD project at CERN provide information about the role of ionizing particles in 'sensitizing' atmospheric aerosols which might, later, give rise to cloud droplets. Our analysis shows that, although important in cloud physics the results do not lead to the conclusion that cosmic rays affect atmospheric clouds significantly, at least if H2SO4 is the dominant source of aerosols in the atmosphere. An analysis of the very recent studies of stratospheric aerosol changes following a giant solar energetic particles event shows a similar negligible effect. Recent measurements of the cosmic ray intensity show that a former decrease with time has been reversed. Thus, even if cosmic rays enhanced cloud production, there will be a small global cooling, not warming.

The proof relies on consideration of the linearized equation together with Palais-Smale condition, thus a combination of topological and variational methods is used. The applications of the result to the control systems with feedback and to the specific nonlinear Volterra equation are presented.

description: Das Feld des Puppen-, Figuren- und Objekttheaters ist in seinen Ausdrucksmöglichkeiten heterogen und formenreich. In der Arbeit wird der Asterisk dazu verwendet, um die Uneindeutigkeit des Phänomens der Puppe* hervorzuheben. Als eines der zentralen Momente der Kunstform wird die Animation verschiedener Körper, Materialien und Figurationen behandelt. Auf den Bühnen des Theaters der Dinge schließen sich Puppen*spieler:in, Puppe*/Objekt und Rezipient:in zu einer untrennbaren Verbindung zusammen, die als Netzwerk oder Gefüge betrachtet, die Handlungsfähigkeit bzw. agency von Gegenständen zu demonstrieren vermag. Die Handlungsfähigkeit nicht-menschlicher Erscheinungen wird über die Erkenntnisse von Jane Bennett, Karen Barad, Bruno Latour, Félix Guattari, Gilles Deleuze und anderen dargestellt. Ebenfalls werden uneindeutige Körperfigurationen – Körper, die sich außerhalb normativer Körperkonzepte bewegen – auf ihr widerständiges Potenzial untersucht. Dabei wird u. A. Bezug zu Judith Butler, Donna Haraway und Antke Engel hergestellt.

description: Objectives. We examined whether stress related to negative body image perception and the desire to lose weight explained some of the body mass index–health gradient.

Methods. We used 2003 Behavioral Risk Factor Surveillance System data to examine the impact of desired body weight, independent of actual body mass index, on the amount of physically and mentally unhealthy days by race, ethnicity, and gender.

Results. The difference between actual and desired body weight was a stronger predictor than was body mass index (BMI) of mental and physical health. When we controlled for BMI and age, men who wished to lose 1%, 10%, and 20% of their body weight respectively suffered a net increase of 0.1, 0.9, and 2.7 unhealthy days per month relative to those who were happy with their weight. For women, the corresponding numbers were 0.1, 1.6, and 4.3 unhealthy days per month. The desire to lose weight was more predictive of unhealthy days among women than among men and among Whites than among Blacks or Hispanics.

Conclusions. Our results raise the possibility that some of the health effects of the obesity epidemic are related to the way we see our bodies.

description: New physics can emerge in magnetic materials where quantum fluctuations are enhanced due to reduced dimensionality and strong frustration. One long sought example is the resonating-valence-bond (RVB) state, where atomic magnetic moments are strongly correlated but do not order or freeze even in the limit of T -> 0. The RVB ground state does not break conventional symmetries, such as lattice translation or spin-rotation. The realization of such a quantum spin liquid in two-dimensions would represent a new state of matter. It is believed that spin liquid physics plays a role in the phenomenon of high-Tc superconductivity, and the topological properties of the spin liquid state may have applications in the field of quantum information. We present neutron scattering measurements of the spin excitations on single crystal samples of the spin-1/2 kagomé lattice antiferromagnet ZnCu3(OD)6Cl2 (also called herbertsmithite). Our observation of a spinon continuum in a two-dimensional magnet is remarkable first. The results serve as a key fingerprint of the quantum spin liquid state in herbertsmithite.

description: Theoretical atmosphere models provide the basis for a variety of applications in astronomy. In simplified one-dimensional (1D) atmosphere models, convection is usually treated with the mixing length theory despite its well-known insufficiency, therefore, the superadiabatic regime is poorly rendered. Due to the increasing computational power over the last decades, we are now capable to compute large grids of realistic three-dimensional (3D) hydrodynamical model atmospheres with the realistic treatment of the radiative transfer. We have computed the Stagger-grid, a comprehensive grid of 3D atmosphere models for late-type stars. In the presented contribution, we discuss initial results of the grid by exploring global properties and mean stratifications of the 3D models. Furthermore, we also depict the differences to classic 1D atmosphere models.

description: Coordinated multi-point (CoMP) schemes have been widely studied in the recent years to tackle the inter-cell interference. In practice, latency and throughput constraints on the backhaul allow the organization of only small clusters of base stations (BSs) where joint processing (JP) can be implemented. In this work we focus on downlink CoMP-JP with multiple antenna user equipments (UEs) and propose a novel dynamic clustering algorithm. The additional degrees of freedom at the UE can be used to suppress the residual interference by using an interference rejection combiner (IRC) and allow a multistream transmission. In our proposal we first define a set of candidate clusters depending on long-term channel conditions. Then, in each time block, we develop a resource allocation scheme by jointly optimizing transmitter and receiver where: a) within each candidate cluster a weighted sum rate is estimated and then b) a set of clusters is scheduled in order to maximize the system weighted sum rate. Numerical results show that much higher rates are achieved when UEs are equipped with multiple antennas. Moreover, as this performance improvement is mainly due to the IRC, the gain achieved by the proposed approach with respect to the non-cooperative scheme decreases by increasing the number of UE antennas.

description: Limiting the number of students per classroom in the early years has been shown to improve educational outcomes. Improved education is, in turn, hypothesized to improve health. The authors examined whether smaller class sizes affect mortality through age 29 years and whether cognitive factors play a role. They used data from the Project Student Teacher Achievement Ratio, a 4-year multicenter randomized controlled trial of reduced class sizes in Tennessee involving 11,601 students between 1985 and 1989. Children randomized to small classes (13–17 students) experienced improved measures of cognition and academic performance relative to those assigned to regular classes (22–25 students). As expected, these cognitive measures were significantly inversely associated with mortality rates (P < 0.05). However, through age 29 years, students randomized to small class size nevertheless experienced higher mortality rates than those randomized to regular size classes (hazard ratio (HR) = 1.58, 95% confidence interval (CI): 1.07, 2.32). The groups at risk included males (HR = 1.73, 95% CI: 1.05, 2.85), whites/Asians (HR = 1.68, 95% CI: 1.04, 2.72), and higher income students (HR = 2.20, 95% CI: 1.06, 4.57). The authors speculate that small classes might produce behavior changes that increase mortality through young adulthood that are stronger than the protective effects of enhanced cognition.

description: Wall adhesion effects during batch sedimentation of strongly flocculated colloidal gels are commonly assumed to be negligible. In this study in-situ measurements of colloidal gel rheology and solids volume fraction distribution suggest the contrary, where significant wall adhesion effects are observed in a 110mm diameter settling column. We develop and validate a mathematical model for the equilibrium stress state in the presence of wall adhesion under both viscoplastic and viscoelastic constitutive models. These formulations highlight fundamental issues regarding the constitutive modeling of colloidal gels, specifically the relative utility and validity of viscoplastic and viscoelastic rheological models under arbitrary tensorial loadings. The developed model is validated against experimental data, which points toward a novel method to estimate the shear and compressive yield strength of strongly flocculated colloidal gels from a series of equilibrium solids volume fraction profiles over various column widths.

description: Objectives. We explored whether a successful randomized controlled trial of early education, the Carolina Abecedarian Project (ABC), which enrolled infants from 1972 to 1977 at the Frank Porter Graham Child Development Institute in Chapel Hill, North Carolina, improved health outcomes and behaviors by 21 years of age.

Methods. ABC randomized 111 infants to receive an intensive early education program or nutritional supplements and parental counseling alone; participants have been followed to the present day. We examined the effect of ABC on health outcomes and behavioral risk factors when participants were aged 21 years, and then explored the mediators of this relationship.

Results. Relative to the control group, the ABC treatment group was previously found to have improved cognition and educational attainment. We found that the intervention also improved heath (P = .05) and health behaviors (P = .03) when participants were aged 21 years. These improvements in behaviors were not mediated by IQ, math and reading scores at 15 years of age, educational attainment, or health insurance.

Conclusions. Effective early education programs may improve health and reduce risky health behaviors in adulthood.

description: We compute the non-Gaussian corrections to the energy density and anisotropies of gravitational waves induced during the radiation era after an ultra-slow-roll phase of inflation by using a diagrammatic approach, and present the corresponding Feynman rules. Our two-loop calculation includes both the intrinsic non-Gaussianity of the inflaton perturbation $δϕ$ and the non-Gaussianity arising from the nonlinear relation between the latter and the curvature perturbation $\mathcal{R}$, which we find to be subdominant with respect to the former. We apply our formalism to an analytical model in which the ultra-slow-roll phase is followed by a constant-roll stage with a nonvanishing second slow-roll parameter $η$, and address the renormalization of the one-loop scalar power spectrum in this scenario.

description: Using ~1,700,000 target- and sky-fiber spectra from the SDSS, we have carried out a systematic search for Galactic planetary nebulae (PNe) via detections of the [OIII] 4959, 5007 lines. Thanks to the excellent sensitivity of the SDSS spectroscopic surveys, this is by far the deepest search for PNe ever taken, reaching a surface brightness of the [OIII] 5007 line down to about 29.0 mag./arcsec^2. The search recovers 13 previously known PNe in the Galactic Caps. In total, 44 new PN candidates are identified, including 7 candidates of multiple detections and 37 candidates of single detection. The 7 candidates of multiple detections are all extremely large (between 21' - 154') and faint, located mostly in the low Galactic latitude region and with a kinematics similar to disk stars. After checking their images in Ha and other bands, three of them are probably HII regions, one is probably associated with a new supernova remnant, another one is possibly a true PN, and the remaining two could be either PNe or supernova remnants. Based on sky positions and kinematics, 7 candidates of single detection probably belong to the halo population. If confirmed, they will increase the number of known PNe in the Galactic halo significantly. All the newly identified PN candidates are very faint, with a surface brightness of the [OIII] 5007 line between 27.0 - 30.0 mag./arcsec^2, very challenging to be discovered with previous techniques and thus may greatly increase the number of "missing" faint PNe. Our results demonstrate the power of large scale fiber spectroscopy in hunting for ultra-faint PNe and other types of emission line nebulae. Combining the large spectral databases provided by the SDSS and other on-going projects (e.g. the LAMOST Galactic surveys), it is possible to build a statistically meaningful sample of ultra-faint, large, evolved PNe, thus improving the census of Galactic PNe.

Narcisismo, Ontologia e il "Dio" delle Teologie Abramitiche: Una Critica Filosofico - Ontologica
Creators: name: PsykoSapiens
Publisher: name: Zenodo
Year: 2025

description: Il testo indaga il legame tra narcisismo ontologico e la concezione del cosiddetto divino nelle tradizioni abramitiche, soffermandosi sull’affermazione “Facciamo l’uomo a nostra immagine”. La tesi proposta interpreta il Dio biblico come manifestazione di un narcisismo autoreferenziale privo di radicamento ontologico, in cui Elohim e YHWH rappresentano espressioni frammentarie di un ordine cosmico alienato dalla realtà materiale.  

La narrazione biblica della creazione diviene paradigma di un atto di autoconferma: l’uomo non è altro che riflesso speculare di un’alterità incapace di fondarsi ontologicamente. Il narcisismo divino, lungi dall’essere ricchezza ontologica, si svela come frammentazione e proiezione umana di bisogni e ansie, costruendo una relazione speculare tra Dio e uomo, entrambi intrappolati in una dinamica alienata.  

L’analisi si spinge infine a riflettere sull’uomo stesso: struttura di carbonio organizzata, prodotto dell’evoluzione e sistema dinamico in costante scambio con l’ambiente, che si interroga sulla propria essenza e sull’abisso tra ciò che è e ciò che pensa di essere. Attraverso questa esplorazione, il testo invita a superare narrazioni consolatorie, abbracciando l’idea del nulla come possibilità di radicamento nell’essere.

description: Emotionen nehmen Einfluss auf das Denken, die Wahrnehmung und Handlungen von Personen (Datler 2012, 11). Sind geistige Kapazitäten von Heranwachsenden durch emotionale Belastungen gebunden, so kann dies Auswirkungen auf den Lernerfolg haben (vgl. Bundschuh 2003, 167). Somit ist auch Schule ein Ort, an dem die emotionale Welt des Kindes Raum haben muss, damit pädagogische Bemühungen erfolgreich sein können. Kreisgespräche können in ihrer Brückenfunktion diesen Erlebnissen physisch und psychisch Raum zur Verfügung stellen. Lehrperson und Gruppe können die Funktion eines Containers nach Bion (1962) übernehmen, um Mitschüler*innen bei der emotionalen Bearbeitung von Erlebtem zu unterstützen. Im Mittelpunkt der Arbeit stehen Containingprozesse, welche in den Kreisgesprächen einer zweiten Klasse Volksschule im Zeitraum von September bis Dezember 2020 stattfanden. Die vorliegende Fallstudie nach Binneberg (1985) und Fatke (1995) zeigt, wie psychoanalytisch-pädagogisches Fallverstehen in der Regelklasse genutzt werden kann, um Schüler*innen der Grundstufe 1 der Volksschule im oben angeführten Sinne gerecht werden zu können. Aktuelle wissenschaftliche Erkenntnisse der Themen „Kreisgespräch“ und „Containment“ werden in den Kontext Schule eingebettet. Mit Hilfe der Methode der Work Discussion werden Containingprozesse in Kreisgesprächen aus Praxisprotokollen, welche im Zeitraum von September bis Dezember 2020 im Zuge eines Work Discussion Seminars entstanden, isoliert, untersucht, interpretiert und die Ergebnisse diskutiert. Der Fokus liegt dabei auf dem*der einbringenden Schüler*in, der Rolle der Lehrperson und der Gruppe als Container. Die Ergebnisse der Fallstudie bestätigen, dass Containment in Kreisgesprächen stattfinden kann. Es zeigt sich, dass eine psychoanalytisch-pädagogische Zugangsweise ein differenziertes Verständnis 1) der eingebrachten Thematik, 2) der emotionalen Involviertheit der einbringenden Schülerin*des einbringenden Schülers, 3) der Gruppendynamik im Kreisgespräch ermöglicht und auch 4) der emotionalen Involviertheit der Lehrperson erlaubt. Dadurch stehen der Lehrkraft zusätzliche Handlungs- und Umgangsmöglichkeiten zur Verfügung. Weiters ergibt die Fallstudie, dass sich die Rolle der Lehrperson im Kreisgeschehen von jener in der üblichen Klassensituation unterscheidet. Auch die konzeptuelle Gestaltung von Kreisgesprächen vor dem Hintergrund des Modells des Containments unterscheidet sich von der allgemeinen Gestaltung von Kreisgesprächen. Die Analyseergebnisse bringen neue Erkenntnisse zu den Möglichkeiten der Anwendung psychoanalytischer Methoden in pädagogischen Settings und erweitern den aktuellen Wissensstand um Containment im Kontext von Schule und Unterricht. Die vorliegende Arbeit richtet sich an all jene Pädagog*innen, die Möglichkeiten suchen, sich in der Regelschule – mit Hilfe eines psychoanalytisch-pädagogischen Zugangs – bewusst mit den emotionalen Bedürfnissen ihrer Schüler*innen auseinanderzusetzen und im Zuge dessen ihre eigenen Handlungsmöglichkeiten zu erweitern.
More Than Ataxia: Hyperkinetic Movement Disorders in Childhood Autosomal Recessive Ataxia Syndromes

description: Background: The autosomal recessive ataxias are a heterogeneous group of disorders that are characterized by complex neurological features in addition to progressive ataxia. Hyperkinetic movement disorders occur in a significant proportion of patients, and may sometimes be the presenting motor symptom. Presentations with involuntary movements rather than ataxia are diagnostically challenging, and are likely under-recognized.

Methods: A PubMed literature search was performed in October 2015 utilizing pairwise combinations of disease-related terms (autosomal recessive ataxia, ataxia–telangiectasia, ataxia with oculomotor apraxia type 1 (AOA1), ataxia with oculomotor apraxia type 2 (AOA2), Friedreich ataxia, ataxia with vitamin E deficiency), and symptom-related terms (movement disorder, dystonia, chorea, choreoathetosis, myoclonus).

Results: Involuntary movements occur in the majority of patients with ataxia–telangiectasia and AOA1, and less frequently in patients with AOA2, Friedreich ataxia, and ataxia with vitamin E deficiency. Clinical presentations with an isolated hyperkinetic movement disorder in the absence of ataxia include dystonia or dystonia with myoclonus with predominant upper limb and cervical involvement (ataxia–telangiectasia, ataxia with vitamin E deficiency), and generalized chorea (ataxia with oculomotor apraxia type 1, ataxia-telangiectasia).

Discussion: An awareness of atypical presentations facilitates early and accurate diagnosis in these challenging cases. Recognition of involuntary movements is important not only for diagnosis, but also because of the potential for effective targeted symptomatic treatment.

description: Background. The educational attainment of a parent is a powerful predictor of children’s wellbeing, but little is known about why this is the case. Methods. We used the 2008 General Social Survey to explore factors that may explain the relationship between one’s father’s education and one’s own mortality. These include (1) intellectual traits, (2) material wellbeing, (3) psychological characteristics, (4) personality characteristics, and (5) social capital. Results. The education credentials of one’s father are significantly associated with one’s risk of death. The strongest mediators are own educational attainment, family income, home ownership, and subjective socioeconomic status. To a lesser extent, respondents’ happiness with friends and work and social bonding were also pathways. Conclusions. A father’s educational attainment appears to influence his children’s health, and may do so not only by improving the child’s material circumstances but also through his or her educational attainment and other psychological and social characteristics.

description: We investigate the correlations between the quark spin and orbital angular momentum inside the nucleon. Similarly to the Ji relation, we show that these correlations can be expressed in terms of specific moments of measurable parton distributions. This provides a whole new piece of information about the partonic structure of the nucleon.

description: Background: The aim was to compare the occurrence of post-injection dysphagia in parkinsonism-related cervical dystonia (PRCD) versus cervical dystonia (CD) of other etiologies (non-PRCD). A secondary objective was to explore potential clinical differences between PRCD and non-PRCD and their respective responses to botulinum toxin (BoNT).

Methods: A cross-sectional chart review was carried out of patients treated for CD with Onabotulinumtoxin A at the University of Florida. We collected demographic information, dose of BoNT injected, patient-reported presence of dysphagia as a side effect, patient-perceived duration of benefit and efficacy according to the Clinical Global Impression Scale (CGIS).

Results: Of the 144 patients included, 24 patients were diagnosed with PRCD and 120 were diagnosed as non-PRCD. Data analysis showed no significant differences in number of weeks of benefit from BoNT (PRCD 9.1±3.7 versus non-PRCD 9.4±3.7 weeks, p = 0.830), BoNT dosage (PRCD 235.0±95.6 versus non-PRCD 263.7±101.3 units, p = 0.181), median CGIS score (median = 2 or “much improved” for both groups, p = 0.88), or the presence of dysphagia after BoNT (PRCD 17% versus non-PRCD 19 %, p = 0.753, n = 132). In a subgroup analysis of the non-PRCD group, patients who experienced dysphagia were older than those who did not (63.9±8.9 years versus 58.1±14.4 years, p = 0.02).

Discussion: Despite an increased baseline risk of dysphagia in patients with PRCD, BoNT appears to be equally safe and equally beneficial in PRCD and non-PRCD patients.
