AWARENESS OF SCABIES AMONG SCHOOL STUDENTS IN HAIL CITY AND ITS SURROUNDING VILLAGES, KSA.

Background: scabies resulted from the burrowing effect of a female parasite, Sarcoptesscabiei. Scabies considered to be one of the possible health problems in our area. The aim of this study was toMeasure the level of awareness of Hail school students and its surrounding villages on scabies. Material:The work was cross-sectional study on different males and females schools, forming three groups; primary, middle and secondary, of Hail city and surrounding villages between 2018 January and 2019. Methods: The collected data, from previously designed questionnaires of different groups, were analyzed by computer using statistical SPSS program. Results: The total mean of awareness of the three groups indicated that the students of secondary schools had the highest awareness level followed by the primary level then middle students, Also the awareness level in female students more than males

A genetic association study of glutamine-encoding DNA sequence structures, somatic CAG expansion, and DNA repair gene variants, with Huntington disease clinical outcomes

BACKGROUND: Huntington disease (HD) is caused by an unstable CAG/CAA repeat expansion encoding a toxic polyglutamine tract. Here, we tested the hypotheses that HD outcomes are impacted by somatic expansion of, and polymorphisms within, the HTT CAG/CAA glutamine-encoding repeat, and DNA repair genes. METHODS: The sequence of the glutamine-encoding repeat and the proportion of somatic CAG expansions in blood DNA from participants inheriting 40 to 50 CAG repeats within the TRACK-HD and Enroll-HD cohorts were determined using high-throughput ultra-deep-sequencing. Candidate gene polymorphisms were genotyped using kompetitive allele-specific PCR (KASP). Genotypic associations were assessed using time-to-event and regression analyses. FINDINGS: Using data from 203 TRACK-HD and 531 Enroll-HD participants, we show that individuals with higher blood DNA somatic CAG repeat expansion scores have worse HD outcomes: a one-unit increase in somatic expansion score was associated with a Cox hazard ratio for motor onset of 3·05 (95% CI = 1·94 to 4·80, p = 1·3 × 10-6). We also show that individual-specific somatic expansion scores are associated with variants in FAN1 (pFDR = 4·8 × 10-6), MLH3 (pFDR = 8·0 × 10-4), MLH1 (pFDR = 0·004) and MSH3 (pFDR = 0·009). We also show that HD outcomes are best predicted by the number of pure CAGs rather than total encoded-glutamines. INTERPRETATION: These data establish pure CAG length, rather than encoded-glutamine, as the key inherited determinant of downstream pathophysiology. These findings have implications for HD diagnostics, and support somatic expansion as a mechanistic link for genetic modifiers of clinical outcomes, a driver of disease, and potential therapeutic target in HD and related repeat expansion disorders.

SPARC 2017 retrospect & prospects : Salford postgraduate annual research conference book of abstracts

Welcome to the Book of Abstracts for the 2017 SPARC conference. This year we not only celebrate the work of our PGRs but also the 50th anniversary of Salford as a University, which makes this year’s conference extra special. Once again we have received a tremendous contribution from our postgraduate research community; with over 130 presenters, the conference truly showcases a vibrant PGR community at Salford. These abstracts provide a taster of the research strengths of their works, and provide delegates with a reference point for networking and initiating critical debate. With such wide-ranging topics being showcased, we encourage you to exploit this great opportunity to engage with researchers working in different subject areas to your own. To meet global challenges, high impact research inevitably requires interdisciplinary collaboration. This is recognised by all major research funders. Therefore engaging with the work of others and forging collaborations across subject areas is an essential skill for the next generation of researchers

Cross-cultural adaptation and validation of the Arabic version of the Physical Activity Scale for the Elderly among community-dwelling older adults in Saudi Arabia

Ayidh M Alqarni,1,2 Vishal Vennu,1 Sulaiman A Alshammari,3 Saad M Bindawas1 1Department of Rehabilitation Sciences, College of Applied Medical Sciences, King Saud University, Riyadh, Saudi Arabia; 2Department of Physical Therapy, King Abdullah Hospital, Bisha, Saudi Arabia; 3Department of Family and Community Medicine, College of Medicine, King Saud University, Riyadh, Saudi Arabia Purpose: Older adults are the fastest growing population group worldwide. Regular physical activity (PA) is reported to reduce the risk of health conditions and improve personal well-being. Few validated instruments can be used to measure the PA levels among older adults in Saudi Arabia. The Physical Activity Scale for the Elderly (PASE) is used worldwide for evaluating the PA levels of the elderly in epidemiological studies. However, this scale has not been translated into Arabic. This study aimed to cross-culturally adapt the PASE into Arabic language and evaluate its reliability and validity among community-dwelling older adults in Saudi Arabia. Patients and methods: This study was a cross-sectional one following Beaton guidelines to translate and perform cultural adaptation, as well as test the reliability and validity of the PASE Arabic version (PASE-A). Elderly (N=74) people from both genders, who lived in a community dwelling in Riyadh city, were selected from several primary health care centers. The study used Cronbach’s alpha coefficient to assess the internal consistency reliability, while intraclass correlation coefficient (ICC2,1) was used for test–retest reliability and the Spearman’s rank correlation coefficient (r) was used to evaluate the correlation among PASE-A and grip strength, Timed Up and Go test, body mass index, and fat percentage. Results: Out of 74 older adults, 59 (79.7%) completed the PASE-A questionnaire twice. The internal consistency of the PASE-A components was good (Cronbach’s alpha 0.70–0.75), and the reliability of the components was excellent (ICC2,1 0.90–0.98). A higher PASE-A score was associated with higher grip strength (r=0.28, p=0.05) and with shorter Timed Up and Go test times (r=-0.45, p=0.01). Conclusion: The PASE-A version was easy, understandable, and relevant for Saudi older adults’ culture. This scale was a reliable and valid tool for evaluating and assessing the PA level among community-dwelling older adults in Saudi Arabia.

Unfortunately, due to a shortage of donors, many patients suffering from their illnesses are waiting for an organ. This study aimed to determine the awareness, attitude, and beliefs toward organ donation among the Saudi population.Patients and Methods: This is an online cross-sectional survey that was conducted in Saudi Arabia between July and September 2022. A self-administered questionnaire was distributed to the general public using an online platform. The questionnaire consists of two sections: the first is about demographic data, and the second is about questions to assess awareness, attitude, and beliefs regarding organ donation. The Chi-squared test was used to examine the differences in participants’ awareness, attitude, and beliefs towards organ donation. A binary logistic regression analysis was used to identify predictors of a positive attitude towards organ donation.Results: A total of 3507 individuals participated in this study. Around 68.1% were aged between 18 and 30 years. Twenty-four percent of them knew of the legislative body for organ donation; 58.5% believed that organ donation should be promoted; and 66.1% had a positive attitude toward donating body organs. Younger age (31– 50 years), male gender, being unemployed or working in a government job, and being married were factors that decreased the likelihood of having a positive attitude towards organ donation.Conclusion: Although there was a positive attitude and belief about organ donation, awareness was suboptimal. Younger age, male gender, being unemployed or working in a government job, and being married were factors that decreased the likelihood of having a positive attitude towards organ donation. It is necessary to address the gaps in knowledge, and social media as well as mass media may have an important role in bridging the gaps.Keywords: organ donation, attitude, knowledge, belief, publi
