Epidemiologic and Clinical Characteristics of Migraine and Tension-Type Headaches among Hospitals Staffs of Shiraz (Iran)

Headache is a common symptom that constitutes a major health problem to all countries in the world. This study was conducted to estimate the prevalence of migraine and tension -type headaches(TTH), its associated occupational risk factors among Shiraz hospitals staffs, and to report on clinical characteristics of migraine and TTH with using the International Headache Society (IHS) diagnosis criteria. A random sam- ple of 1023 staffs constituting a 20% sample of the hospitals staff population was selected. Sampling method was categorical random sampling. Within each group sampling was carried out systematically. Data were col- lected by screening questionnaire followed by clinical interviews, general physical and neurological examina- tion, and diagnostic criteria of IHS. Prevalence of migraine, TTH and coexisting migraine and TTH were es- timated as 11.2% (115 cases), 19.5% (199 subjects) and 3.2% (33 subjects) respectively. In this study , clini- cal characteristics of headache including type, site, number , intensity ,concomitant symptom of headaches had been surveyed. TTH and migraine headaches were significantly associated with self reported abnormal sleep pattern and female gender (P < 0.001). Also TTH was negatively associated with total 24hr duration of sleep and history of involvement in second job significantly (P<0.026). The average of prevalence of mi- graine and TTH were lower than their counter parts in western countries but higher than previous studies conducted in other Asian countries. Clinical characteristics were almost parallel with IHS criteria, headache- related missed work rates were higher for subjects with migraine headache, and also TTH and migraine were separate disorders and were not as a part of a continuum of headache disorders. Headache disorders deserve more attention, especially concerning strategies leading to adequate primary prevention, diagnosis and treat- ment.
Deviations from Matthiessen’s rule and resistivity saturation effects in Gd and Fe from first principles

According to earlier first-principles calculations, the spin-disorder contribution to the resistivity of rare-earth metals in the paramagnetic state is strongly underestimated if Matthiessen's rule is assumed to hold. To understand this discrepancy, the resistivity of paramagnetic Fe and Gd is evaluated by taking into account both spin and phonon disorder. Calculations are performed using the supercell approach within the linear muffin-tin orbital method. Phonon disorder is modeled by introducing random displacements of the atomic nuclei, and the results are compared with the case of fictitious Anderson disorder. In both cases the resistivity shows a nonlinear dependence on the square of the disorder potential, which is interpreted as a resistivity saturation effect. This effect is much stronger in Gd than in Fe. The non-linearity makes the phonon and spin-disorder contributions to the resistivity non-additive, and the standard procedure of extracting the spin-disorder resistivity by extrapolation from high temperatures becomes ambiguous. An "apparent" spin-disorder resistivity obtained through such extrapolation is in much better agreement with experiment compared to the results obtained by considering only spin disorder. By analyzing the spectral function of the paramagnetic Gd in the presence of Anderson disorder, the resistivity saturation is explained by the collapse of a large area of the Fermi surface due to the disorder-induced mixing between the electronic and hole sheets.
Risk factors for domestic elder abuse and cognitive decline: A comparative study with a Spanish sample

ABSTRACT The purpose of this study is threefold: (1) to ascertain the relationship between elder abuse and cognitive decline; (2) to compare the variables associated with the risk of abuse in a group of people with cognitive decline and another group without cognitive decline; and (3) to study whether cognitive decline and three other variables are related to the caregiver predicted risk of abuse. The cases of 200 elders and their caregivers were assessed by social service professionals. The results identified a relationship between cognitive decline and abuse. Although some variables were associated with a risk of abuse in both groups, others were observed to be specific to the group of elders with cognitive decline. Other predictors of abuse included the quality of the past relationship, the perceived burden of care, the caregiver’s willingness to assume the caregiving role, and the ability of the caregiver to manage difficult situations.
Predicting UML Statechart Diagrams Understandability Using Fuzzy Logic-Based Techniques

In this work, we present an application of the Fuzzy Logic in the field of prediction in Software Engineering. We specifically use the Fuzzy Prototypical Knowledge Discovery for characterizing the UML statechart diagrams according to their understandability, starting from the structural complexity and size of the diagrams, expressed by means of metrics, and the Fuzzy Deformable Prototypes, to obtain a prediction model of the understandability time of the UML statechart diagrams. The obtained model, built from data obtained through experimentation, is valid –in a certain waysince the 75% of the estimated values are at least 70% accurate, although it is necessary further validation with data obtained from real projects.
Iatrogenic retinal breaks during 20-gauge vitrectomy for proliferative diabetic retinopathy

Background We classified iatrogenic retinal break formation during 20-gauge pars plana vitrectomy for proliferative diabetic retinopathy into three types according to the mechanism of development, and evaluated the association of each type with postoperative complications. This is the largest series of such patients published to date. Methods This was a retrospective comparative study of 760 eyes from 609 cases who underwent primary 20-gauge vitrectomy for proliferative diabetic retinopathy and were followed-up for at least 6 months after surgery. Postoperatively, the eyes were classified as having vitreous hemorrhage only (group 1), fibrovascular membrane without traction retinal detachment (group 2), or fibrovascular membrane with traction retinal detachment (group 3). Results The overall incidence of iatrogenic retinal breaks was 29%. Fibrovascular membrane dissection was associated with retinal break formation in 50 of the eyes in group 3, an incidence which was significantly higher than that in group 2 (P < 0.001). Posterior vitreous detachment creation and peripheral vitreous shaving were associated with retinal break formation in 8% of eyes overall, and oral dialysis occurred in 2%. Postoperatively, vitreous hemorrhage requiring washout, neovascular glaucoma, recurrent retinal detachments, and fibrovascular proliferation at the sclerotomy sites occurred in 4%, 4%, 3%, and 1%, respectively, of all eyes. Outcomes of eyes with these postoperative complications, other than vitreous hemorrhage, were poor. Multiple regression analysis revealed retinal break formation during fibrovascular membrane dissection to be significantly related to postoperative vitreous hemorrhage (P = 0.019), recurrent retinal detachments (P < 0.001), and neovascular glaucoma (P = 0.048). Oral dialysis was also significantly related to postoperative vitreous hemorrhage (P = 0.001). Conclusion Iatrogenic retinal break formation during fibrovascular membrane dissection was more likely to be the cause of poor outcomes than peripheral retinal breaks or oral dialysis.
Dynamic Simulation of the Effects of Graft Fixation Errors During Medial Patellofemoral Ligament Reconstruction

Background: Medial patellofemoral ligament (MPFL) reconstruction is performed to prevent recurrent instability, but errors in femoral fixation can elevate graft tension. Hypothesis: Errors related to femoral fixation will overconstrain the patella and increase medial patellofemoral pressures. Study Design: Controlled laboratory study. Methods: Five knees with patellar instability were represented with computational models. Kinematics during knee extension were characterized from computational reconstruction of motion performed within a dynamic computed tomography (CT) scanner. Multibody dynamic simulation of knee extension, with discrete element analysis used to quantify contact pressures, was performed for the preoperative condition and after MPFL reconstruction. A standard femoral attachment and graft resting length were set for each knee. The resting length was decreased by 2 mm, and the femoral attachment was shifted 5 mm posteriorly. The simulated errors were also combined. Root-mean-square errors were quantified for the comparison of preoperative patellar lateral shift and tilt between computationally reconstructed motion and dynamic simulation. Simulation output was compared between the preoperative and MPFL reconstruction conditions with repeated-measures Friedman tests and Dunnett comparisons against a control, which was the standard MPFL condition, with statistical significance set at P < . 05. Results: Root-mean-square errors for simulated patellar tilt and shift were 5.8° and 3.3 mm, respectively. Patellar lateral tracking for the preoperative condition was significantly larger near full extension compared with the standard MPFL reconstruction (mean differences of 8 mm and 13° for shift and tilt, respectively, at 0°), and lateral tracking was significantly smaller for a posterior femoral attachment (mean differences of 3 mm and 4° for shift and tilt, respectively, at 0°). The maximum medial pressure was also larger for the short graft with a posterior femoral attachment than for standard MPFL reconstruction, with a significant increase in the mean value of 1.6 MPa at 30°. Conclusion: MPFL reconstruction reduces lateral tracking, but nonanatomic femoral fixation and overtensioning the graft overcorrect patellar tracking and increase pressure applied to medial patellar cartilage. Clinical Relevance: Errors in femoral fixation and graft tensioning can lead to postoperative loss of flexion and overloading of medial cartilage.
Seven Years of Advanced Synthetic Aperture Radar (ASAR) Global Monitoring (GM) of Surface Soil Moisture over Africa

A surface soil moisture (SSM) product at a 1-km spatial resolution derived from the Envisat Advanced Synthetic Aperture Radar (ASAR) Global Monitoring (GM) mode data was evaluated over the entire African continent using coarse spatial resolution SSM acquisitions from the Advanced Microwave Scanning Radiometer for Earth Observing System (AMSR-E) and the Noah land surface model from the Global Land Data Assimilation System (GLDAS-NOAH). The evaluation was performed in terms of relative soil moisture values (%), as well as anomalies from the seasonal cycle. Considering the high radiometric noise of the ASAR GM data, the SSM product exhibits a good ability (Pearson correlation coefficient (R) = ~0.6 for relative soil moisture values and root mean square difference (RMSD) = 11% when averaged to 5-km resolution) to monitor temporal soil moisture variability in regions with low to medium density vegetation and yearly rainfall >250 mm. The findings agree with previous evaluation studies performed over Australia and further strengthen the understanding of the quality of the ASAR GM SSM product and its potential for data assimilation. Problems identified in the ASAR GM algorithm over arid regions were explained by azimuthal effects. Diverse backscatter behavior over different soil types was identified. The insights gained about the quality of the data were used to establish a reliable masking of the existing ASAR GM SSM product and the identification of areas where further research is needed for the future Sentinel-1-derived SSM products.
Description of the direct teaching activities of itinerant teachers of deaf and hard of hearing students

ABSTRACT This study sought to describe and classify the support activities provided by all itinerant teachers for students who are deaf or hard of hearing (DHH) in regular schools in the Australian Capital Territory (ACT), without exclusion. The itinerant teachers (n = 14) varied in terms of formal qualifications and experience and provided support to all DHH (n = 61) students in ACT schools, inclusive of students across all age/grade levels and those with additional disabilities. Analysis of teachers’ responses to a detailed questionnaire provided frequency and time measures for 22 possible activities, which were simplified using factor analysis into 11 categories of activities. Categorization of the activities indicated that 91% of the support time was used for direct teaching, and that 73% of the direct teaching time was primarily focused on the development of skills in language, listening, and speech. The other 27% of the direct teaching time was used for explicit class programme support. As well as providing direct teaching, the itinerant teachers provided consultation services to school personnel and parents. The findings are discussed in relation to the previous literature describing the activities of itinerant teachers of DHH students.
What kind of love is love at first sight? An empirical investigation

Love at first sight (LAFS) is a commonly known phenomenon, but has barely been investigated scientifically. Major psychological theories of love predict that LAFS is marked by high passion. However, it could also be a memory confabulation construed by couples to enhance their relationship. We investigated LAFS empirically by assessing feelings of love at the moment participants met potential partners for the first time. Data were collected from an online study, a laboratory study, and three dating events. Experiences of LAFS were marked neither by high passion, nor by intimacy, nor by commitment. Physical attraction was highly predictive of reporting LAFS. We therefore suggest that LAFS is not a distinct form of love, but rather a strong initial attraction that some label as LAFS, either in the moment of first sight or retrospectively.
Optimal Unemployment Insurance with Hidden Search

After first reviewing recent results on optimal unemployment insurance (UI) with unobserved search effort and hidden savings, this paper identifies that lump sum layoff payments play an important role. Simulations find that coordinating constant UI paid to the unemployed, with a severance payment that fully compensates for the drop in permanent income by being laid-off yields payoffs which are surprisingly close to the full information benchmark. By improving the value of employment, severance payments improve search incentives through re-entitlement effects. Thus severance payments are employment enhancing, though for reasons which are quite distinct from those given in the firing cost literature.
The Variable Impacts of Public Housing Community Proximity on Nearby Street Robberies

Objectives: Use crime pattern theory to investigate the proximity effects of public housing communities on robbery crime while taking into account the presence of nearby nonresidential facilities. Method: The study uses data describing 41 Philadelphia public housing communities and their surrounds. Surrounds are defined using two increments of street block-sized buffers. Multilevel models (buffer areas nested around public housing communities) allowing the proximity effect to vary across communities and predicting its shape with public housing level predictors are estimated. Results: The multilevel models show that the shape of proximity effects varies across public housing communities and depends on community size, even after factoring in presence of nonresidential facilities. Spatially, multiple public housing communities close to one another have more intense robbery patterns. Conclusions: Labeling all public housing communities as equally criminogenic robbery exporters is unwarranted. In fact, some communities have lower robbery counts than the areas surrounding them. Consequently, effectively addressing robbery in and around public housing communities will require careful consideration of where the problem is located. Locating public housing communities more than two blocks apart may reduce robbery.
Youth Athlete Sport Commitment Following Multiple Concussions and Persistent Symptoms

The purpose of this Master’s research was to explore factors involved in youth athletes’ sport commitment decision following multiple concussions and persistent symptoms. Individual semi-structured interviews were conducted with 11 pre-adolescent and adolescent athletes (three males, eight females) between 12 and 18 years of age (M = 15.25). Participants were involved in a variety of sports including soccer (n = 3), hockey (n = 3), basketball (n = 1), cheerleading (n = 1), gymnastics (n = 1), jiu-jitsu (n = 1), and rugby (n = 1). Based on the data emanating from the interviews, two articles were written. In article one, the sport commitment model (SCM) (Scanlan, Chow, Sousa, Scanlan, & Knifsend, 2016) facilitated the exploration of the determinants of youth athletes’ sport commitment following multiple concussions and persistent (i.e., lasting beyond 28 days) symptoms. A further objective was to expand upon the current SCM by exploring other potential determinants specifically related to return to play after multiple concussions. Findings indicated that sport enjoyment, valuable opportunities, and the desire to excel were the most salient sources of sport commitment. Constructs pertaining to social influences were the least influential in athletes’ sport commitment. Findings also supported the addition of athletic identity as a new construct in the SCM. Article two uncovered the psychosocial challenges faced by youth athletes during recovery and return to play following multiple concussions and protracted symptoms. The findings revealed that athletes with concussions experience concerns about persistent symptoms, re-injury anxiety, a diminished perceived ability, lack of social support, and emotional turmoil and mental health problems. Finally, findings provided insight into the potential role concussions and ensuing psychosocial challenges may play in mental health and wellbeing. Collectively, this research improves the understanding of difficulties experienced by youth athletes following multiple concussions and supports the need to improve concussion education and foster a more supportive environment.

A hillslope-based hydrological model using catchment area and width functions

Abstract A flow-interval hillslope discretization scheme is proposed for catchment hydrological modelling. By this scheme, a two-dimensional catchment is simplified into a one-dimensional cascade of flow intervals linked by the main stream. Each flow interval comprises a set of parallel hillslopes. The hillslope is the fundamental computational unit in the hydrological model providing lateral inflow to the main stream. The size of hillslope is determined by the catchment area and width functions. Catchment runoff is the total of hillslope responses through the river routing. Tests in four Japanese catchments showed that the model performed well on simulating the overall water balance, general flow pattern, and daily and hourly hydrographs of a whole catchment, as well as simultaneous simulation in different subcatchments. Characteristics of catchment hydrological responses and model applicability are discussed.
Growth , and Morphological Alterations Carcinoma Cells : Inhibition of Plasminogen Activators , Cell Glucocorticoid Sensitivity of OVCA 433 Human Ovarian Updated

OVCA 433 human ovarian carcinoma cells secrete large amounts of plasminogen activator (PA), which consists of immunologically identifi able urokinase (UK) and tissue-type PA (tPA). Total extracellular PA activity is 95% inhibited by treatment of cells with 1 x IO"7 M dexamethasone (Dex) for 3 days. This inhibition is both time and concentration dependent, with half-maximal inhibition occurring after 1.5 days with 1 x 10~7 M Dex, or with 1 x 10"' M Dex for 3 days, respectively. Interestingly, the loss of UK activity precedes the loss of tPA activity, such that half-maximal inhibition of the two PA types occurs at 1 and 2 days, respectively. Dex treatment leads to approximately 50% inhibition of cell growth and pronounced morphological alterations, including marked enlargement, flattening, and multinucleation. Treatment of the cells with other classes of steroid hormones, i.e., estrogens, progestins, androgens, and mineralocorticoids, is without effect on UK and tPA activities, cell growth, or morphology. OVCA 433 cells contain about 14,000 nuclear glucocorticoid receptors (GR) per cell (measured at 37Â°C), with an average affinity (K<) for |3H]Dex of 6.6 x 10"' M. Only active glucocorticoids compete with [}H]Dex for nuclear GR binding sites. Our results demonstrate steroid-specific glucocorticoid responsiveness of ovarian carcinoma cells, a tumor cell type not usually considered hormonally responsive. Since almost 90% of ovarian carcinoma tumor biop sies contain GR (M. C. Galli, et al., Cancer (Phila.), 47: 1297-1302, 1981), it is possible that glucocorticoid sensitivity could be exploited clinically, particularly following the almost universal development of resistance to the chemotherapeutic drugs commonly used in this disease.
A Multi-Institutional Phase II Study of the Efficacy and Tolerability of Lapatinib in Patients with Advanced Hepatocellular Carcinomas

Background: Hepatocellular carcinoma (HCC) is on the rise worldwide. HCC responds poorly to chemotherapy. Lapatinib is an inhibitor of epidermal growth factor receptor and HER2/NEU both implicated in hepatocarcinogenesis. This trial was designed to determine the safety and efficacy of lapatinib in HCC. Methods: A Fleming phase II design with a single stage of 25 patients with a 90% power to exclude a true response rate of <10% and detect a true response rate of ≥30% was used. The dose of lapatinib was 1,500 mg/day administered orally in 28-day cycles. Tumor and blood specimens were analyzed for expression of HER2/NEU/CEP17 and status of downstream signal pathway proteins. Results: Twenty-six patients with HCC enrolled on this study. Nineteen percent had one prior therapy. Most common toxicities were diarrhea (73%), nausea (54%), and rash (42%). No objective responses were observed. Ten (40%) patients had stable disease as their best response including six (23%) with stable disease lasting >120 days. Median progression-free survival was 1.9 months and median overall survival was 12.6 months. Patients who developed a rash had a borderline statistically significant longer survival. Tissue and blood specimens were available on >90% of patients. No somatic mutations in EGFR (exons 18-21) were found. In contrast to our previous findings, we did not find evidence of HER2/NEU somatic mutations. PTEN, P-AKT, and P70S6K expression did not correlate with survival. Conclusions: Lapatinib is well-tolerated but seems to benefit only a subgroup of patients for whom predictive molecular or clinical characteristics are not yet fully defined.
