Knowledge,attitude and practices of healthcare professionals of Riyadh,Saudi Arabia towards covid-19: A cross-sectional study

Background & objectivesCOVID-19 is an emerging pandemic that necessitates the implementation of effective infection prevention and control steps. The knowledge, attitudes, and practices (KAP) of healthcare professionals toward COVID-19 affect their compliance to prevention and control initiatives. During the evolving pandemic, we examined the KAP among healthcare professionals against COVID-19 in this research.Materials and methodsThis was a cross-sectional study conducted among Riyadh region health care professionals from the beginning of December 2020 to the end of February 2021 using a validated self-administered questionnaire. The knowledge questionnaire contained questions about COVID-19 clinical characteristics, prevention, and management. The evaluation of attitudes and practices included questions regarding actions and adjustments in COVID-19 response activities. Knowledge scores were measured and compared using demographic characteristics, as well as attitudes and practices toward COVID-19. Using SPSS-IBM 25, bivariate statistics were done to analyze the data.Results146 healthcare professionals completed the survey. Physicians were the most prominent party in the survey, accounting for 74 (51 percent), followed by nurses 44 (30 percent) and pharmacists 28 (19 percent). The participants' average age was 39.69 ± 8.48 years. The participant's mean knowledge, attitude, and practice scores were 11.43 ± 1.34, 3.89 ± 0.93, and 3.85 ± 0.81, respectively. With a positive attitude, the mean knowledge score was 11.52, and with proper practice, it was 11.32. With an improvement in knowledge, the attitude score increased significantly (r = 0.172, P = 0.001). Besides, there was a greater association between attitudes and practices (r = 0.170, P = 0.029). A significant enhancement in the practice score of the professionals was noted with an increase in knowledge score (r = 0.095, P = 0.010), an indicator for a positive correlation between practice and knowledge scores.Interpretation & conclusionHealthcare practitioners have a good understanding of COVID-19. Improved knowledge and a positive attitude toward COVID-19 infection are linked to appropriate practice. There is a need for more manpower, better COVID-19 management training, and strategies to reduce anxiety among healthcare professionals.     

Attitude and awareness of public towards genetic testing in Riyadh,Saudi Arabia

The current study was designed to evaluate the attitude of the Saudi general population towards knowledge, perception and awareness about genetic testing. Using a convenience sampling technique, an online survey was used to collect the data. The survey consisted of 16 questions that covered basic demographics and several scenarios that assess subjects’ perceptions regarding genetic testing. Answering all questions was required for completing the survey. Among 333 subjects, 53.5% were male, 18.9% were married, and 99.4% were muslims. Around 75% has/will have a bachelor degree. About 59% were students. About 87% would consider genetic testing before marriage and similar percentage would not consider conceiving a child if the genetic screening indicated that there is 100% chance the child will be born with genetic disorder. Neither marital status (Single = 87.04%, married = 87.30% (P = 0.955)) nor gender (male = 85.96, female = 88.39 (P = 0.509)) affected the aforementioned decision. When subjects were asked if they would choose abortion knowing that the embryo has a severe genetic disorder, 62.7% answered yes. In general, 80.4% were willing to be recruited into a genetics study, married subjects were more reluctant to be recruited compared to singles (30% and 17% (P = 0.018) respectively). There was no difference between males and females in the decision of joining a genetic study. Also 78.4% supported creation of genetic disease database and family maps. 69.7% of the participants supported government enforcement of the genetic testing, 56.2% supported government-run facilities for Saudi citizens to have genetic tests. We conclude that married people were in favor of genetic testing than the single counterparts, secondly, single status people supported the idea of having genetic tests before their marriage they were supportive of the idea of the government taking a leading role in enforcing the genetic testing and creation of the genetic banks.     

Flexibilidad psicológica,burnout y satisfacción vital en profesionales que trabajan con personas afectadas de demencia

IntroductionThe clinical complexity of dementia, its physical burden, and the potential assaults associated with psychological and behavioral symptoms, could put healthcare workers working with dementia at high risk of burnout. Certain attitudes toward dementia and certain coping styles may be a protective factor against the stress experienced by these workers. On the other hand, it has been shown that a coping style based on psychological flexibility can prevent the development of burnout in the workplace. The present study analyzes the relationship between levels of burnout, psychological flexibility, attitudes towards dementia and life satisfaction in a sample of healthcare workers who work with people affected by dementia.MethodsA sample of 105 healthcare workers from the Ricard Fortuny Social Hospital was recruited (day hospital, hospitalization unit, and nursing home), and psychological flexibility (AAQII), burnout levels (MBI), life satisfaction (SWL), anxiety (STAI-R), and attitudes towards dementia (EAD) were assessed.ResultsPsychological inflexiblility showed a positive relationship with 2 dimensions of burnout (emotional exhaustion [r = .342, P < .01]; depersonalization [r = .328, P < .01]), and with anxiety (r = .723, P < .01), and also showed a negative relation with life satisfaction (r = ?.485, P < .01) and affect attitude (r = ?.209); p < .05). It was also found a negative relation between rejection attitude with emotional exhaustion (r = ?.328, P < .01) and with depersonalization (r = ?.328; P < .01).ConclusionsThose participants with greater psychological flexibility, in addition to feel more satisfaction with life, were found to be less likely to feel emotionally exhausted, to depersonalize patients with dementia, and felt more affection for them. On the other hand, no relationship was found between Burnout levels and the cognitive dimension of Attitudes towards dementia (the worker's knowledge of dementia). The results have significant implications regarding the type of training that is given to healthcare workers who work with people affected by dementia. Psychoeducational interventions promoting the psychological flexibility could help to reduce the risk of burnout in healthcare workers who work with dementia.     

Slovakian Pupils' Knowledge of,and Attitudes toward,Birds

ABSTRACT

As the world's biodiversity is being destroyed, costs for nature protection activities increase. One proposed way to increase people's pro-environmental attitudes is to increase their knowledge base. It has been suggested that knowledge and attitudes are related, but no consensus in this field yet exists. Thus, the investigation of the relationship between attitudes and knowledge has valuable implications for nature protection programs. In this paper, we investigated relationships between Slovakian grammar school pupils' attitudes to, and knowledge of, birds (n = 402 participants aged 10–19 years). We found that factual knowledge about birds was positively related to pupils' attitudes toward birds. Interestingly, younger pupils had better knowledge of birds than older pupils. Regarding attitudes, higher scores were registered for the Concern for Birds and Avoidance of Birds dimensions than the Interest in Birds dimension. Females showed more positive attitudes in the Avoidance of Birds dimension compared with males, and bird owners scored higher in the Interest in Birds dimension and lower in the Concern for Birds dimension compared with non-bird owners. Implications for nature protection programs are discussed.     

Measuring farmers' attitude towards breeding tools: the Livestock Breeding Attitude Scale

Under-use of genetic improvement tools and low participation in breeding programmes are key drivers of breeding programmes under-performance. Both aspects are heavily influenced by farmers attitudes which, to date, have not been analysed in an objective and systematic manner. A key factor constraining the implementation of attitudinal studies towards livestock breeding tools is the lack of a reference scale for measuring attitudes. In this research, we provide the livestock breeding sector with such a reference measure. We developed the scale following the standardized psychometric methodologies and statistical tools. Then, as a case study, we used the scale to explore the attitudes of beef and dairy sheep farmers in Australia, New Zealand and Spain and analysed farmer and farming system factors related to those attitudes. Fourteen sheep and beef breed associations facilitated the implementation of a survey of 547 farmers, generating data that was used for the scale evaluation. The relationship between attitudinal factors and farmer and farming system factors was analysed using generalized linear models across and within breeds. The results suggest that the 8-item definitive scale we have developed is appropriate to measure farmer attitudes. We found that attitudes towards genetic improvement tools have two components; i) traditional selection and ii) genetic and genomic selection combined. This means that positive attitudes towards traditional phenotypic selection do not necessarily imply a negative attitude towards genetic and genomic selection tools. Farmer attitudes varied greatly not only across the studied breeds, species and countries, but also within them. High-educated farmers of business-oriented farms tend to have the most negative attitude towards traditional selection. However, attitudes towards genetic and genomic selection tools could not be linked to these factors. Finally, we found that the breed raised had a large effect on farmer attitude. These findings may help in the evolution of breeding programmes by identifying both the farmers most inclined to uptake breeding innovations in the early stages of its establishment and the farmers who would be more reluctant to participate in such programmes, thus informing where to focus extension efforts.     

Science attitudes and knowledge among preclinical medical students in Pokhara, Nepal

Knowledge of science and the scientific method are important in learning about and using evidence-based medicine in practice. Courses in research methodology have been introduced for both medical students and practicing doctors. In Pokhara, the basic science subjects are taught in an integrated manner during the first four semesters of the undergraduate medical course. Studies on students' attitudes towards and knowledge of science are lacking in medical colleges in Nepal. Hence the study was carried out to obtain information on students' attitude towards and knowledge of science and scientific methodology among preclinical medical students and note the association, if any, of students' attitudes and their demographic characteristics. The study was carried out in March 2005 among the students of the first four semesters at the Manipal College of Medical Sciences, Pokhara, Nepal using a questionnaire developed by Hren and coworkers. Two hundred and twenty students (overall response rate 73.3%) successfully completed the questionnaire. Seventy-five respondents were Nepalese, 115 were Indians, 27 were Sri Lankans and 3 belonged to other nationalities. The X +/- SD total attitude score was 147.4 +/- 10.8 (neutral score 135). The X +/- SD scores on the subscales, value of science to humanity, value of scientific methodology and value of science to medicine were 51.3 +/- 5.4, 39.6 +/- 3.7 and 58.5 +/- 5.9 (neutral scores were 36, 51 and 48 respectively). The knowledge score measured using a set of 8 multiple choice questions was 3.3 +/- 1.4. The attitude scores were lower and the knowledge score was comparable to that reported previously in a study in Croatia but higher than that reported from Southeast Europe.     

Awareness and attitudes of final-year pharmacy students towards chronotherapy: a needs analysis

Chronotherapy involves the administration of medication in coordination with the body’s circadian rhythms to maximise effectiveness and/or minimise/avoid adverse effects. A deeper understanding of the concepts underpinning chronotherapy and emerging applications in pharmacy practice would be an important addition to the scope of education in future graduates. This study aimed to assess baseline awareness level and attitude towards the principles of chronotherapy among final-year pharmacy students at the University of Sydney and to uncover underlying ‘gaps’ in their knowledge of the evidence-based information on chronotherapy in practice. A cross-sectional survey instrument was utilised. A questionnaire was designed to establish the knowledge base and attitudes toward principles of chronotherapy. Out of 216 students, 212 students completed the questionnaire resulting in a response rate of 98 %. Mean total awareness and attitude scores were 6.6 ± 2.0 (score range 0–13) and 47.4 ± 6.9 (score range 12–60), respectively. The study indicated that the final-year pharmacy students have a positive attitude and willingness to apply principles of chronotherapy in future practice despite having a lack of awareness regarding circadian rhythms and evidence-based information on chronotherapy. The finding points to the need for an educational intervention based on the principles of chronotherapy in pharmacy schools.

     

Therapeutic effect of autologous bone marrow stem cell mobilization combined with anti-infective therapy on moyamoya disease

ObjectiveThe purpose of this study is to explore the therapeutic effect of autologous bone marrow stem cell (ABMSC) mobilization combined anti-infection therapy on patients with moyamoya disease (MMD), and to provide reference for the clinical treatment of MMD and cerebrovascular disease.Methods54 adult patients with MMD diagnosed in Henan Provincial People’s Hospital from March 2017 to March 2019 were chosen as research objects. All patients were randomly divided into study group (SG) and control group (CG), with 27 patients in each group. Patients in both groups received conventional drug treatment after diagnosis of MMD, and received dura turnover of brain - temporal muscle - superficial temporal artery application surgery during indirect vascular reconstruction. On the basis of surgical treatment, patients in the SG were given ABMSC mobilization combined with low-dose dexamethasone for anti-inflammatory and anti-infection treatment. ABMSCs were mobilized by recombinant human granulocyte colony stimulating factor (rhG-csF) and recombinant human granulocyte - macrophage colony stimulating factor (rhoM-esF). The therapeutic effects of the patients were evaluated BF, one month after treatment (AF), three months AF, and six months AF. The number of hematopoietic stem cells (HpCs) and inflammatory indicators were compared between the two groups before and 4 weeks AF.ResultsFirstly, the Barthcl index of patients in the two groups showed a gradual increase trend at the 3rd and 6th months AF, and the ascensional range in the research group was higher than that in the CG (P < 0.05). Secondly, at the 3rd and 6th month AF, national institute of heath stroke scale (NIHSS) scores of patients in the CG were lower than those before treatment (BF), and there was an important change in NIHSS scores between the two groups at the same period (P < 0.05). Thirdly, after 1 month of treatment and 3 months of treatment, Chinese stroke scale (CSS) scores of patients in both groups decreased obviously compared with those BF, and the SG was lower than the CG, with statistical changes (P < 0.05). Fourthly, after 4 weeks of treatment, the hematopoietic stem cell counts in both groups were higher than those BF, and the hematopoietic stem cell counts in the SG were obviously higher than those in the CG (P < 0.05). All three inflammatory indicators were improved compared with those BF, and the SG was better than the CG (P < 0.05).ConclusionAutogenous bone marrow stem cell mobilization combined with dexamethasone anti-inflammation and anti-infection treatment after revascularization in patients with MMD can accelerate the recovery of nerve function and promote the formation of new blood vessels. At the same time, it can reduce inflammation and improve patients' quality of life, which is worthy of clinical reference.     

Regional differences in awareness and attitudes regarding genetic testing for disease risk and ancestry

Little is known about the lay public’s awareness and attitudes concerning genetic testing and what factors influence their perspectives. The existing literature focuses mainly on ethnic and socioeconomic differences; however, here we focus on how awareness and attitudes regarding genetic testing differ by geographical regions in the US. We compared awareness and attitudes concerning genetic testing for disease risk and ancestry among 452 adults (41% Black and 67% female) in four major US cities, Norman, OK; Cincinnati, OH; Harlem, NY; and Washington, DC; prior to their participation in genetic ancestry testing. The OK participants reported more detail about their personal ancestries (p = 0.02) and valued ancestry testing over disease testing more than all other sites (p < 0.01). The NY participants were more likely than other sites to seek genetic testing for disease (p = 0.01) and to see benefit in finding out more about one’s ancestry (p = 0.02), while the DC participants reported reading and hearing more about genetic testing for African ancestry than all other sites (p < 0.01). These site differences were not better accounted for by sex, age, education, self-reported ethnicity, religion, or previous experience with genetic testing/counseling. Regional differences in awareness and attitudes transcend traditional demographic predictors, such as ethnicity, age and education. Local sociocultural factors, more than ethnicity and socioeconomic status, may influence the public’s awareness and belief systems, particularly with respect to genetics.     

A protective effect of curcumin on cardiovascular oxidative stress indicators in systemic inflammation induced by lipopolysaccharide in rats

ObjectiveInflammation has been considered as an important factor in cardiovascular diseases (CVD). Curcumin has been well known for its anti-inflammatory effects. In current research, protective effect of curcumin on cardiovascular oxidative stress indicators in systemic inflammation induced by lipopolysaccharide (LPS) was investigated in rats.Material and methodsThe animals were divided into five groups and received the treatments during two weeks [1]: Control in which vehicle was administered instead of curcumin and saline was injected instead of LPS [2], LPS group in which vehicle of curcumin plus LPS (1 mg/kg) was administered [3-5], curcumin groups in them three doses of curcumin (5, 10 and 15 mg/kg) before LPS were administered.ResultsAdministration of LPS was followed by an inflammation status presented by an increased level of white blood cells (WBC) (p < 0.001). An oxidative stress status was also occurred after LPS injection which was presented by an increased level of malondialdehyde (MDA) while, a decrease in thiols, superoxide dismutase (SOD) and catalase(CAT) in all heart, aorta and serum (p < 0.001). The results also showed that curcumin decreased WBC (doses: 10 and 15 mg/kg) (p < 0.001) accompanying with a decrease in MDA (P < 0.01 and P < 0.001). Curcumin also improved the thiols and the activities of SOD and catalase (P < 0.05, P < 0.01 and P < 0.001).ConclusionBased on our findings, curcumin can ameliorates oxidative stress and inflammation induced by LPS in rats to protect the cardiovascular system.     

Knowledge and Attitudes towards Antibiotic Use and Resistance - A Latent Class Analysis of a Swedish Population-Based Sample

BackgroundIn 2006, a study investigating knowledge and attitudes regarding antibiotic use and resistance in Sweden, indicated high level of knowledge but also areas in need of improvement.Objective(i) To provide an update on the knowledge and attitudes to antibiotic use and resistance of the Swedish population, and (ii) to identify which groups within the population are in particular need of improved knowledge or attitudes.MethodsA questionnaire was sent by post in 2013 to 2,500 randomly-selected individuals aged 18–74, living in Sweden. Latent class analyses were conducted to group respondents based on their responses. The association between socio-demographic characteristics and the probability of belonging to each latent class was assessed.ResultsThe response rate was 57%. Ninety-four per cent of the responders knew that bacteria could become resistant to antibiotics and the majority answered correctly to the questions regarding antibiotic resistance development. The respondents expressed confidence in doctors who decided not to prescribe antibiotics. Three latent classes related to ‘knowledge regarding antibiotic use and resistance’, two regarding ‘attitudes towards antibiotic accessibility and infection prevention’ and three regarding ‘attitudes towards antibiotic use and effects’ were revealed. Men, younger and more educated people were more knowledgeable but males had a less restrictive attitude. Respondents with high levels of knowledge on antibiotics were more likely to have appropriate restrictive attitudes to antibiotics.ConclusionKnowledge on antibiotic use and resistance is maintained high and has improved in Sweden compared to 2006. People with lower education and elderly are especially in need of improved knowledge about antibiotic use and resistance.     

Diabetes knowledge: Are resident physicians and Nurses adequately prepared to manage diabetes?

ObjectiveTo assess and compare the diabetes knowledge of nurses and residents in surgery, internal medicine, and family practice.MethodsA 21-question survey based on current diabetes standards of care was developed and administered. The results were stratified by type of participant and analyzed statistically.ResultsA total of 52 internal medicine residents (IMR), 21 family practice residents (FPR), 42 surgery residents (SR), and 48 registered nurses (RN) participated. The survey had good overall internal consistency (Cronbach α of 0.78) and test-retest reliability (Pearson correlation coefficient of 0.71). The total mean percent correct for all participants was 61%. The total scores of IMR, FPR, and RN groups were similar (69%, 64%, and 66%) and significantly greater (P < 0.001) than the SR score (44%). Collectively, all survey participants averaged less than 50% correct on several items. The IMR scored higher than the SR and FPR on several items. The nurses outscored the physicians on items regarding insulin preparations, treatment of hypoglycemia, and perioperative insulin management. A subgroup of 13 RN with additional diabetes training earned the highest total score (82%).ConclusionOur novel survey was shown to be a statistically valid tool for assessment of diabetes knowledge. IMR, FPR, and inpatient RN have similar but insufficient levels of knowledge about diabetes. SR may have a more profound deficit of diabetes knowledge. Previous additional diabetes training among nurses was associated with greater diabetes knowledge. Most nurses and residents require additional education in order to provide optimal care to patients with diabetes. (Endocr Pract. 2007;13: 17-21)     

Impact of polycystic ovary syndrome on eating behavior,depression and health related quality of life: A cross-sectional study in Riyadh

Background & objectivesPolycystic ovary syndrome (PCOS) is the most common endocrinal disorder, and the greatest cause of infertility in women. Despite availability of individual data on impact of multiple endocrinal, reproductive and even metabolic factors in PCOS individuals, the data on the co-existence of BED and depression in PCOS patients with its relationship on the quality of life in Saudi Arabian females is not found. Hence this study is aimed to elucidate the implication of PCOS on eating behaviour, induction of depression and general health quality in Saudi Arabian population of Riyadh.Materials and methodsThis is a cross-sectional study carried out in multiple health facilities of Riyadh from January to March 2019. The study samples (494) were recruited by convenience sampling and administered validated questionnaire by trained research participants. The data obtained was analysed by binary logistic regression using SPSS-IBM 25.ResultsOf the total 494 women participated in the study, 23.48% (116) were PCOS individuals. The odds of developing abnormal health related quality of (HRQ) in patients with PCOS was significantly (P = 0.000, OR = 3.472) high when compared to non-PCOS participants. The odds of showing high binge eating disorder (BED, P = 0.007, OR = 2.856) and depression (P = 0.000, OR = 2.497) scores in PCOS participants were significantly more than patients who were not having PCOS. Out of the three parameters studied, abnormal health related quality of life possessed a higher influence of PCOS compared to depression and abnormal eating behavior.Interpretation & conclusionIn conclusion, the present study shows that women with PCOS are at a significant risk for depressive disorders, disorganized eating behavior and impaired quality of life. Therefore, necessary care and screening is required to minimize the impact of PCOS on already burdened individuals.     

Skin dose in radiation treatment of the left breast: Analysis in the context of prone versus supine treatment technique

PurposeTo determine how the skin dose varies in patients receiving radiation treatment for breast cancer in the prone and supine positions.MethodsFifty patients were scanned in the prone and supine positions. A radiation treatment plan was created for the left breast using a 6-MV beam for a prescribed dose of 42.66 Gy in 16 fractions. The dose was calculated using 1- and 2.5-mm calculation grid sizes and the surface dose was compared in both techniques.ResultsThe median gantry angles relative to the skin surface at the central axis were 8 and 52 degrees for treatment in the prone and supine positions, respectively. The mean dose difference between the prone and supine techniques was statistically significant from 3- to 5-mm depth for both grid sizes. For the 1-mm calculation grid size, the doses at 3-, 4-, and 5-mm depths in the prone and supine techniques were 87.80% and 89.10% (P < 0.003), 91.92% and 94.50% (P < 0.00), and 95.30% and 98.20% (P < 0.00), respectively; for the 2.5-mm grid size, the respective doses were 87.10% and 88.59% (P < 0.00), 91.60% and 94.63% (P < 0.00), and 95.10% and 97.80% (P < 0.00), respectively.ConclusionsThis study demonstrates that the prone technique facilitates a relatively lower skin dose than the supine technique. This observation is probably due to the beam angle. The beam is more perpendicular to the skin surface in the prone technique, whereas it is more tangential in the supine technique, which may deliver a higher skin dose. Thus, the dose to the skin should be evaluated in the prone technique, and if desired, the skin dose could be carefully augmented via a bolus or beam spoiler.     

Sex-specific differences in the prevalence of sarcopenia among pre-frail community-dwelling older adults in Saudi Arabia

ObjectivesTo assess sex differences in the prevalence of sarcopenia among pre-frail community-dwelling older adults in Saudi Arabia.MethodsThis was a cross-sectional study conducted at a tertiary-level hospital in Riyadh, Saudi Arabia, in 2019. The study participants were pre-frail community-dwelling older adults, according to the Edmonton Frail Scale. The SARC-F questionnaire was used to diagnose sarcopenia. The Katz Activities of Daily Living (ADL) was used to rank the adequacy of performance in six functions: bathing, dressing, toileting, transferring, continence, and feeding, while the Lawton Instrumental Activities of Daily Living scale was used to assess the more complex ADL necessary for living in the community.ResultsIn total, 283 community-dwelling older adults were recruited for this study, with a mean (±SD) age of 70.77 (±6.26) years; 72.7% of the total were female participants. The majority (85.5%) of the patients reported that they needed home care assistance. The mean ADL score of the participants was high, indicating high function and independence (KATZ-ADL: M 4.60 SD 1.75; Lawton Brody: 60%). The overall prevalence of sarcopenia among the studied participants was 65.7%, which was significantly higher among females (71.9%) than among males (59.1%), with a P-value of 0.007. Among the demographic characteristics of the participants, there was a significant difference in the need for home care assistance in female sarcopenic and non-sarcopenic participants (74.1% vs. 25.9%, p = 0.017), but without demonstrable difference in males. Additionally, there was a significant difference (P < 0.05) in the prevalence of sarcopenia between male and female participants according to ADL scores. The strongest predictor for sarcopenia prevalence in males was an ADL score <2 according to the Katz index, with an odds ratio of 6.5, while the need for home care was the only significant predictor of sarcopenia among female participants (OR 3.25, CI: 1.14–9.25, p = 0.02).ConclusionOverall, almost two-thirds of the studied pre-frail community-dwelling older adult population were sarcopenic. The prevalence of sarcopenia was significantly higher among females than males. The strongest predictor of sarcopenia was an ADL score <2 based on the Katz index in males and the need for home care assistance in females.     

Expression and pathogenesis of VCAM-1 and VLA-4 cytokines in multiple myeloma

ObjectiveThe objective of this study is to investigate the expression of Vascular cell adhesion molecule-1 (VCAM-1) and very late appearing antigen-4 (VLA-4) cytokines in MM (multiple Myeloma).MethodForty patients with MM are selected as the experimental group and 30 healthy persons as the control group. Flow cytometry is used to detect the expression of VCAM-1 (CD106), VLA-4 (CD49d), CD38 and CD138 antigens in experimental group and control group. ELISA (Enzyme Linked Immunosorbent Assay) is used to detect the concentration of VCAM-1 in serum of experimental group and control group. RT-PCR is used to detect the expression of VCAM-1.ResultsThe positive rate and antigen expression rate of VACM-1 antigen in the experimental group were significantly higher than those in the control group (P < 0.05). There were statistical differences of VLA-4 and VCAM-1 antigens between the initial diagnosis group and the relapse/refractory group, and between the relapse/refractory group and the platform stage group (P < 0.05). There were significant differences between VLA-4 antigen and VACM-1 antigen, phase I and phase II, and between phase I and phase III (P < 0.05). The concentration of VCAM-1 and the expression of VCAM-1 mRNA in the experimental group were significantly higher than (P < 0.01). In the different stages of ISS (International Staging System) and different disease groups in the experimental group, the concentration of VCAM-1 and the expression level of VCAM-1 mRNA are significantly different among the three groups of stage I, II and III (P < 0.01). There is a significant difference between the initial diagnosis group, the relapse/refractory group and the platform group (P < 0.05).ConclusionThere are abnormal expressions of adhesion molecules VCAM-1 and VLA-4 in multiple myeloma patients, which are related to ISS staging.     

Prevalence and predictors of non-alcoholic fatty liver disease in tertiary care hospital of Taif,Saudi Arabia: A retrospective study

BackgroundThe prevalence of nonalcoholic fatty liver disease (NAFLD) in Saudi Arabia is predicted to exceed 30% by 2030. NAFLD leads to liver fibrosis, thus increasing morbidity and health care burden. Obesity and diabetes have been strongly associated with NAFLD in different cities in Saudi Arabia.ObjectivesTherefore, we aim to determine the prevalence rate of NAFLD and specific risk factors for NAFLD among patients of tertiary care hospital of Taif city.Material and methodsWe retrospectively analyzed the medical records of patients for two years, between Feb 2017 and Feb 2019, (n = 100) referred to the hepatology clinic at King Abdulaziz Specialist Hospital in Taif. The diagnosis of NAFLD was based on the radiology report for patients who were aged >20 years old. Other parameters including fasting blood glucose (FBG), platelets count, alanine transaminase (ALT), aspartate transaminase (AST) and total bilirubin were statistically analyzed.ResultsWe found that 40% (P < 0.05) of all patients had NAFLD. The results revealed that a significantly high number of patients with NAFLD have high FBG levels (75%, P < 0.0001) and total bilirubin (P < 0.05). Meanwhile, platelet count was significantly reduced in patients with NAFLD (P < 0.05).ConclusionNAFLD can be a serious health problem in the Taif region. In addition, high FBG is a significant specific risk factor for NAFLD. Health care providers should pay more attention to limiting the prevalence of NAFLD and its risk factors.     

Actitudes y ansiedad ante la muerte en personas mayores pertenecientes a 2 culturas diferentes: España y Egipto

Background and objectiveThere are multiple variables that influence fear of death, as well as attitudes towards it, including age, religiosity, emotional and cultural aspects. Due to the proximity to death, the study of attitudes and death-related anxiety and the variables that influence it in the elderly population is of great relevance. The aim of the present study was to compare the levels of death anxiety, fear of death, attitudes towards death and associated emotional aspects (anxiety and depression) in older adults from 2 different cultures, Western and Arab.Materials and methodA total of 91 people over 60 years old took part and were divided into 2 groups, one of people born in Spain (n = 46) and the other of people born in Egypt (n = 45). In an individualised assessment, participants completed the DAS, PRAM and the anxiety and depression subscales of the SCL-90-R questionnaires.ResultsStatistically significant differences between groups were observed in fear of death, acceptance and emotional aspects. Predictors of anxiety and fear of death were different for each group.ConclusionThe results show the importance of taking into account cultural, religious and emotional aspects in the evaluation of fear and attitudes towards death in the elderly population.
