Neck pain and hand grip strength in dentists of Saudi Arabia

Hand grip is the functional unit of dentists used in firm holding of instruments and tools. Muscles of hand grip supplied by cervical nerves. Dentists put their neck in high physical load for prolonged time that lead to neck pain. 54.4% of dentists in K.S. A. have neck pain and 21% drop out of their job. Objective: The main objective is to correlate neck pain intensity with hand grip strength in dentists of Saudi Arabia. Methodology: Subjects: 25 chronic neck pain dentists (suffering from neck pain more than 3 months) in both gender, were selected. Their ages ranged from 25 to 40 years with normal BMI (18.5-25). they were divided into 3 subgroups according to neck position during their work. Procedures: Pain intensity will be determined by visual analog scale (VAS), hand grip strength will be measured by Jamar hand dynamometer in kilogram (Kg) unit. Result: Among 25 dentists the result showed extremely significant correlation between neck pain intensity and hand grip strength (direct proportional). Discussion and conclusion: the findings of this study denote presence of direct proportional correlation between neck pain intensity and hand grip strength which may be attributed to deficits in sensory motor integration and neuro hyper excitability found in neck pain victims.
Soluble transferrin receptor and risk of type 2 diabetes in the obese and nonobese

Studies evaluating the relationship between soluble transferrin receptor (sTfR), a biomarker inversely related to body iron stores, and risk of type 2 diabetes mellitus (T2DM) are scarce and inconclusive. Furthermore, sTfR concentrations have been observed to be significantly higher in obese than in nonobese individuals. Therefore, the aim of this study was to assess the relationship between sTfR and the risk of T2DM in obese and nonobese subjects.
Are Consumer and Brand Personalities the Same

Current discussions of brand personality refer to a personified brand image, that is, a brand image that can possess any attributes of consumers, rather than brand personality. From a conceptual and methodological critique of the literature, this paper applies the definition of personality to brand personality, and tests the idea using a peer-rating methodology that focuses on each individual's perception of a brand (the brand × subject structure). The results reveal that consumers reflect their personalities by the brands they use, but the relationship between brand choice and symbolic dimensions (i.e., extraversion, agreeableness, neuroticism, and openness to experience) is much stronger than the relationship with functional dimensions (i.e., conscientiousness). Moreover, the pattern of this relationship remains consistent across symbolic and utilitarian products, which implies that consumers choose brands with similar personalities to theirs across various products. The study concludes that an abridged personality scale, based on the Big Five, can be applied to both brands and consumers.
INITIAL VALIDATION OF THE ASSESSMENT OF PARENTING TOOL: A TASK- AND DOMAIN-LEVEL MEASURE OF PARENTING SELF-EFFICACY FOR PARENTS OF INFANTS FROM BIRTH TO 24 MONTHS OF AGE.

Parenting self-efficacy (PSE) includes parents' self-perceptions regarding their capabilities in performing the numerous and changing tasks associated with parenting a specific child (i.e., domain-specific PSE) as well as their self-perceptions in the parenting role overall (i.e., domain-general PSE). Prior literature has demonstrated PSE's relations with numerous constructs significant to mental health and the parent-infant relationship. Prior measures of PSE have been limited by focusing on only domain-specific or domain-general PSE, ignoring the importance of infant development to PSE, and other psychometric limitations. This article presents sound psychometric data for a new measure of PSE, the Assessment of Parenting Tool (APT). The APT includes task-level items on the Domain-Specific subscale (APT-DS) for each age-referenced version of the measure as well as a domain-general subscale that taps overall PSE within the first 24 months' postpartum. Initial construct validity of the measure is established, particularly for parents of infants aged 3 months and older. A stable, three-factor structure for the domain-general subscale includes "coping with being a parent," "attuned parenting," and "self-perceived model parenting. " Future directions for the APT, including a revised checklist format for the domain-specific subscale, are included.
Insights on earthquake triggering processes from early aftershocks of repeating microearthquakes

Characterizing the evolution of seismicity rate of early aftershocks can yield important information about earthquake nucleation and triggering. However, this task is challenging because early aftershock seismic signals are obscured by those of the mainshock. Previous studies of early aftershocks employed high‐pass filtering and template matching but had limited performance and completeness at very short times. Here we take advantage of repeating events previously identified on the San Andreas Fault at Parkfield and apply empirical Green's function deconvolution techniques. Both Landweber and sparse deconvolution methods reveal the occurrence of aftershocks as early as few tenths of a second after the mainshock. These events occur close to their mainshock, within one to two rupture lengths away. The aftershock rate derived from this enhanced catalog is consistent with Omori's law, with no flattening of the aftershock rate down to the shortest resolvable timescale ∼0.3 s. The early aftershock rate decay determined here matches seamlessly the decay at later times derived from the original earthquake catalog, yielding a continuous aftershock decay over timescales spanning nearly 8 orders of magnitude. Aftershocks of repeating microearthquakes may hence be governed by the same mechanisms from the earliest time resolved here, up to the end of the aftershock sequence. Our results suggest that these early aftershocks are triggered by relatively large stress perturbations, possibly induced by aseismic afterslip with very short characteristic time. Consistent with previous observations on bimaterial faults, the relative location of early aftershocks shows asymmetry along strike, persistent over long periods.
Impaired endothelium-dependent vasodilation of coronary resistance vessels is associated with exercise-induced myocardial ischemia.

BACKGROUND The release of endothelium-derived relaxing factors has been shown experimentally to be of pivotal importance for the maintenance of coronary blood flow during increased demand. In humans with coronary atherosclerosis, endothelial vasodilator dysfunction is not confined only to epicardial conductance vessels but may also extend into the coronary microcirculation. We therefore tested the hypothesis that endothelial vasodilator dysfunction of the coronary resistance vasculature is associated with myocardial ischemia during exercise in patients without hemodynamically significant epicardial artery stenoses. METHODS AND RESULTS Coronary vasodilator function was assessed by subselective infusion of the endothelium-dependent dilator acetylcholine (0.036 to 3.6 micrograms/mL) and the endothelium-independent dilator papaverine (7 mg). Coronary blood flow responses were evaluated by intracoronary Doppler flow velocity recordings and quantitative angiography. Exercise-induced myocardial perfusion was determined by 201Tl single photon emission computed tomographic imaging. Thirteen patients had exercise-induced myocardial perfusion defects suggestive of myocardial ischemia, whereas 14 patients had normal thallium imaging during exercise. In patients with exercise-induced thallium perfusion defects, coronary blood flow responses to acetylcholine were significantly (P < .005) blunted compared with patients with normal thallium imaging during exercise. In contrast, coronary blood flow reserve to the endothelium-independent smooth muscle relaxant papaverine was similar in the two groups. Patients with exercise-induced thallium perfusion defects exhibited a significantly (P < .005) reduced (23.9 +/- 9.0% [mean +/- SD]) endothelium-mediated coronary vasodilator capacity compared with patients with normal thallium testing (56.2 +/- 27.8%). Epicardial artery vasoreactivity to acetylcholine did not differ between the two groups. CONCLUSIONS Impaired endothelium-dependent vasodilation of the coronary microcirculation is associated with exercise-induced myocardial ischemia in patients without hemodynamically significant epicardial artery lesions. Endothelial vasodilator dysfunction extending into the coronary microcirculation may thus contribute to the ischemic manifestations of coronary artery disease during times of increased myocardial demand.
Data Distribution and Analysis: A Step to Improving Nursing Quality

&NA; Measurement is a cornerstone for improvement activities, and although the MetroHealth Medical Center in Cleveland, OH, gathered a significant amount of improvement data, it did not have a consistent mechanism for sharing the data with the nursing unit and the frontline nursing staff. A process was implemented to improve data distribution, thus making the data more accessible. Following the implementation of this process, the frontline nurses were more engaged in improvement activities, and significant improvement was noted on several measures. The findings suggest that consistent and meaningful data distribution is an important component in improving the quality of care.
Assessment of microbial health hazards associated with wastewater application to willow coppice, coniferous forest and wetland systems

Treatment and reuse of wastewater by irrigation of willow coppice, forest or wetlands may create new exposure routes for pathogens. This thesis summarises results from a series of field and laboratory studies aimed at identifying and quantifying the microbial health hazards associated with such alternative wastewater treatment systems. Leaching and retention of viruses in the soil-plant system were studied in a lysimeter experiment using a bacteriophage as model organism. The presence and die-off of pathogens was studied in three full-scale systems with wastewater irrigation of willow in southern Sweden. The reduction in pathogens was also studied in microcosms under controlled conditions. In addition, the presence and die-off of pathogens in two wetlands was studied. Finally, a risk assessment was made in order to identify and quantify the most important exposure routes of pathogens. In the Swedish full-scale systems, the average reduction in microorganisms in the wastewater treatment plants was in the range 1.3-2.5 log10. Analyses of faeces collected in the irrigated area did not indicate an increase in pathogens in mammals and birds, whereas indicator organisms were detected in foliage and in some groundwater samples in the fields. The results of the lysimeter study showed very high retention of viruses in sandy soils, whereas leaching to groundwater was substantial and extremely rapid in the clay soil. In the microcosm study Campylobacter were rapidly reduced (<3 h) while Salmonella bacteria were highly resistant. No single factor (light, temperature or radiation) was found to govern the reduction. In the wetlands studied, the reduction in suspended particles seemed to be the main factor controlling bacterial elimination from the water phase. In the sediment, survival of microorganisms was prolonged. The theoretical microbial risk assessment indicated a substantial risk of viral infections caused by direct contact with the wastewater, with aerosols from irrigation, or by drinking contaminated groundwater.
Implementation of K-means clustering method to distribution of high school teachers

Currently, the government is still having difficulties in distributing teachers. The current problem is not just about less teachers, but also more teachers in some cities. The problem of unequal distribution of teachers then became dependent on local government. The distribution of teachers now can not be centralized because of the decentralization system implemented in Indonesia. Clustering in data mining is useful for finding distribution patterns within a dataset that is useful for data analysis processes. Using clustering, identifiable densely populated areas, overall distribution patterns and attractive associations between data attributes. The purpose of this research is to apply ¿-means clustering algorithm to analyze distribution of high school teachers in Indonesia. This research uses three steps, namely dataset selection, preprocessing data, and application of k-means clustering. Testing is done by using k cluster, that is k = 12. The cluster results are analyzed to classify clusters into 3 categories, namely less, enough, and more teachers. Testing results obtained data Sum of Squared Error (SSE) with percentage 87.15%. While the clustering results produce clusters 3 and 5 in the category of less teachers. Cluster 1 and 9 in the category of enough teachers. While cluster 2,4,6,7,8,10,11,12 in the category of more teachers. Based on the results obtained it can be concluded that the accuracy of the algorithm used with 12 clusters is very high. The results of this clustering analysis can also be used as a reference for the distribution of teachers to region with less teachers, so as to solve the issue of uneven distribution of teachers.
Prevalence of Constipation Among the General Population: A Community-Based Survey From India

Constipation is a frequent health problem leading to great discomfort to the person and affects his or her quality of life. It is considered to be highly prevalent in the general population, but there is little data supporting the findings. This study was undertaken with an objective to assess the prevalence of constipation and its associated factors among the general population of Dadu Majra Colony, UT, Chandigarh, India. A total of 505 individuals were interviewed through structured questionnaire based on ROME II criteria for constipation. Results revealed that the prevalence of self-reported constipation within the last 1 year was 24.8% whereas 16.8% of participants had constipation according to the Rome II criteria. Most of the subjects (83%) were within the age group of 18–59 years with mean age (years) of 38.64 ± 15.57. Constipation was significantly more frequent in females than in males (20% vs. 13%) and in nonworking population than in working population (20% vs. 12%). Poor dietary habits, lesser fluid intake per day, and lesser physical activity were found to be significant factors leading to the constipation. About 18% of constipated subjects reported physicians' consultation, whereas 8% reported the use of laxatives to relieve their constipation.
Personal values of Internet users: a cluster analytic approach

Values are an important topic that has received significant scholarly attention from various academic disciplines. The theoretical framework used for individual values research is Schwartz’s value theory that defines ten basic values: power, achievement, hedonism, stimulation, self-direction, universalism, benevolence, tradition, conformity, and security. In order to better understand the motivational background of attitudes and behavior of Internet users, the paper explores the structure of their personal values. A large telephone survey in Croatia in 2016 was conducted on a nationally representative sample of 2,060 Internet users. Values were measured with the Short Schwartz’s Value Survey instrument. Internet users are grouped in different value-related groups with K-means cluster analysis. Furthermore, differences among those value-related groups of Internet users are examined with regard to their levels of social trust, computer anxiety, need for privacy online, online privacy concern and demographics. There were three mutually exclusive groups of Internet users found, namely: power-oriented group, self-centered group and self-transcendent group. Significant differences were found among those groups regarding social trust, expressed computer anxiety and need for privacy online. Demographic characteristics in terms of gender, age, education, income, and occupation explain the observed differences among the clusters of Internet users.
Consumer Health Information Needs and Question Classification: Analysis of Hypertension Related Questions Asked by Consumers on a Chinese Health Website

This study built up a classification schema of consumer health questions which consisted of 48 quaternary categories and 35 annotation rules. Using such a schema, we manually classified 2,000 questions randomly selected from nearly 100 thousand hypertension-related messages posted by consumers on a Chinese health website to analyze the information needs of health consumers. The results showed questions in the categories of treatment, diagnosis, healthy lifestyle, management, epidemiology, and health provider choosing were 48.1%, 23.8%, 11.9%, 5.2%, 9.0%, and 1.9% respectively. The comparison of the questions asked by consumers and physicians showed that their health information needs were significantly different (P<0.0001).
Distributed representations of politicians

Methods for generating dense embeddings of words and sentences have grown rapidly in prominence over the past few years. However, social scientists are often more interested in understanding the authors of text – such as politicians, journalists, and thinktanks – rather than individual words, sentences, and paragraphs. While existing methods such as word2vec and doc2vec can be easily aggregated to author representations, it is unclear whether this aggregation step would produce meaningful vector representations. In this study, we examine the performance of several of these methods at generating dense vector representations of Kenyan politicians based on a corpus of legislative speeches between 1998 and 2012. We evaluate the resulting vectors on several tasks, with disappointing results. We conclude that despite the recent enthusiam about distributed representations for text, more work is needed to effectively extend these methods to representations of the individuals and organizations that author these texts. This work is especially needed in situations involving small and homogneous corpora – precisely the datasets that social scientists often find themselves working with.
Chattering Free Simplex Sliding Mode Control for Systems with Mono-directional Actuators

This paper considers regular simplices of vectors, the exploitation of which is analyzed in the simplex sliding mode control of multi-input uncertain nonlinear systems. The method is extended to eliminate the chattering phenomenon. To this end an estimation procedure based on second order sliding mode algorithms is coupled with a simplex sliding mode control of an augmented order system. The methodology is applied to affine systems with mono-directional actuators
The frequency, causes and prevention of severe urinary dysfunction after radical hysterectomy

Summary. Urinary dysfunction that developed in 58 patients treated by radical hysterectomy, with or without total vaginectomy and whole pelvic irradiation over a 10‐year period, was studied retrospectively by case record review and telephone enquiry. Seven of the 58 (12%) were found to be severely handicapped, six by incontinence and enuresis, and one by the complete inability to void. Twenty‐one (36%) patients had absent bladder sensation or urine loss that caused only minor inconvenience. Advancing age, the menopause, whole pelvic irradiation, and total vaginectomy did not increase the likelihood of developing long‐term urinary problems. The determining factor was whether the most lateral portions of the cardinal and uterosacral ligaments had been resected or spared at the time of surgery. It is concluded that serious disability may be avoided by conserving the lateral portions of the pelvic ligaments while obtaining adequate surgical margins during radical hysterectomy.
Clonal diversity of Salmonella enterica serotype Typhi isolated from patients with typhoid fever in Tehran

In this study, antimicrobial susceptibility test and genetic typing were used to characterize 15 Salmonella enterica serotype Typhi (S. Typhi) isolates recovered from sporadic cases of typhoid fever in Tehran, Iran during 2004. Antimicrobial susceptibility test showed that all isolates were susceptible to 20 antimicrobials examined in this study. Analysis of insertion elements showed that 2 IS200 types with 10 and 11 copies were present. 11 of the 15 isolates were found to possess 10 IS200 elements residing on fragments from 23 to 2.3 kb. Comparison of the RiboPrinter (automated ribotyping) patterns of S. Typhi showed that 60% (9/15) of the isolates belonged to a single ribotype. PCR based random amplified polymorphic DNA analysis (RAPD) and enterobacterial repetitive intergenic consensus (ERIC) and pulsed-field gel electrophresis (PFGE) were also performed. ERIC and RAPD-PCR method showed 2 and 3 genotyping patterns amongst the isolates, respectively. The PFGE typing was carried out by using XbaI restriction enzyme, and 7 restriction patterns were observed. Overall, the molecular typing methods applied in this study showed that the isolated S. Typhi populations were highly polyclonal as shown by PFGE.
Calcium transients recorded with arsenazo III in the presynaptic terminal of the squid giant synapse

Transient changes in free intracellular Ca2+ concentration were monitored in the presynaptic terminal of the giant synapse of the squid, by means of the Ca2+-sensitive dye arsenazo III. Calibration experiments showed a linear relation between the amount of Ca2+ injected by iontophoresis into the terminal, and the peak size of the arsenazo light absorbance record. A light signal could be detected on tetanic stimulation of the presynaptic axon bathed in sea water containing 45 mm Ca2+. During a 1 s tetanus the light signal rose approximately linearly, even though transmitter release declined rapidly and the light signal subsequently declined with a half-time of 2-6 s. The Ca2+ transient elicited by single nerve impulses was recorded by signal averaging, and showed a time course very much slower than the duration of transmitter release.
