The association between overweight/obesity and psychological distress: A population based cross-sectional study in Saudi Arabia

ObjectivesThe objective of this study was to compare the association between mental well-being between obese (classes 1 and 2), over-weight and non-obese population-based individualsMethodsA population-based cross-sectional study was conducted in Al-Kharj, Saudi Arabia. A total of 1019 Saudi nationals aged ≥ 18 years participated in the survey. BMI scores were used to categorize participants into three groups: Obese, overweighted and non-obese/non-overweight. Mental well-being was evaluated by using the validated Arabic version of the General Health Questionnaire version 12 (GHQ-12).ResultsWe used total GHQ score (Mean=12; SD=5.23) to compare mental well-being between the four BMI class categories. The overall one-way ANOVA model was statistically significant (F = 7.018, d = 6, P < 0.001). In multivariate analysis, after adjusting for sociodemographic variables, diabetes and smoking statuses we found that higher psychological distress (as evident by a higher total GHQ score) was associated with higher BMI. The unstandardized Beta regression coefficient = 2.627; P = 0.034). Females were more likely to have higher psychological distress than males (unstandardized Beta = 1.466, P = 0.003). Job status whether being unemployed or ‘civilian’ (civil worker) was significantly associated with higher psychological distress (unstandardized Beta = 1.405, P = 0.041). Being diabetic has a 1.6 times higher risk of psychological distress (unstandardized Beta = 1.604, P = 0.027).ConclusionThe study highlights the public health implications of psychological distress amongst individuals with overweight and obesity in Saudi Arabia. Future longitudinal studies should explore the temporality of this relationship.     

The frequencies of Kidd blood group antigens and phenotypes among Saudi blood donors in Southwestern Saudi Arabia

BackgroundThe patients who require transfusion are prevalent in the Jazan Province, Saudi Arabia. Therefore, it is essential to know the frequency of blood group antigens in such a population. The Kidd blood group system (JK) has two antithetical antigens, Jk^a and Jk^b. Antibodies to these antigens may result in delayed hemolytic transfusion reactions. The present study investigated the frequencies of Jk^a and Jk^b and the phenotypes among Saudi blood donors living in the Jazan Province.MethodsOne hundred and forty-three samples from anonymous Saudi volunteer blood donors in the Jazan Province were serotype to detect Jk^a and Jk^b using gel card technology and determine the phenotypes of the JK blood group system.ResultsThe prevalence of Jk^a and Jk^b antigens were 90.64% (n = 126) and 69.40% (n = 93), respectively. The JK phenotypes were 34.96% Jk(a + b ? ) (n = 51), 12.59% Jk(a ? b + ) (n = 18), 52.45% Jk(a + b + ) (n = 75), and 0% Jk(a ? b ? ). The frequencies of the JK phenotypes in the Jazan population were significantly different from those in the Asian population (P < 0.05).ConclusionsWe reported the frequencies of the Jk^a and Jk^b antigens and the distribution of the JK phenotypes in a group of Saudi blood donors in the Jazan Province, Saudi Arabia. The phenotype Jk(a + b + ) was the most common among the study population. Furthermore, this study emphasizes the significance of identifying the frequency of JK antigens and phenotypes in the provinces of Saudi Arabia.     

Association between self-care management practices and glycemic control of patients with type 2 diabetes mellitus in Saud Arabia: A cross –sectional study

ObjectiveIn this cross-sectional study, we aimed to determine the association of self-care management practices and glycemic control of type 2 diabetes mellitus in Saudi Arabia.MethodsA total of 352 type 2 diabetes mellitus (T2DM) patients from two public tertiary hospitals in Saudi Arabia participated in this study. All T2DM patients were recruited and interviewed by a researcher between January to April 2018 from the outpatient diabetes clinics. All respondents answered a four-part questionnaire which includes demographics data, Diabetes Self-Management Questionnaire (DSMQ). Linear Regression was performed to assess the significance of predictors and compute the coefficient of determination.ResultsThe mean age of the participants was 51.89 ± 10.94. Of the 352 participants, 52% were obese (BMI: ≥30 kgm²) and 77% of the participants had glycated haemoglobin (HbA1c) over 7%. The analysis showed that subscale of Glucose management was the strongest predictor of Hba1c levels of participants’ followed by physical activity. Gender and marital status emerged as significant predictors for their self-care management practices. Female patients had more self-care management practices than male patients (B 0.20; 95CI 0.10– 0.96 (p = 0.015).ConclusionThis study provides an evidence on the self-care management of T2DM patients in Saudi Arabia. The high self-care management found in the study highlights that the patients are aware of the severity of and possible complications associated with T2DM.     

Evaluation of the composition and in vitro antimicrobial,antioxidant, and anti-inflammatory activities of Cilantro (Coriandrum sativum L. leaves) cultivated in Saudi Arabia (Al-Kharj)

BackgroundIn the present study, we explored the composition of Cilantro (Coriandrum sativum L. leaves) essential oil (CEO) cultivated in Saudi Arabia (Al-Kharj) and explored its antioxidant, antimicrobial, and anti-inflammatory effects in vitro.MethodsGas chromatography-mass spectroscopy was used to detect the CEO composition. The 2, 2-diphenyl-1-picrylhydrazyl (DPPH)-induced free radical and ferric chloride scavenging methods were used to determine the antioxidant activity. Antimicrobial activity was investigated using the well diffusion method. Anti-inflammatory activity was evaluated using egg albumin and trypsin-induced inflammation methods.ResultsForty-six compounds representing 90.17% of the total aroma were identified in the CEO; the major constituents were found to be 1-decanol (17.85%), decanal (11.04%), trans-2-dodecen-1-ol (7.87%), menthone (6.71%), 2-decen-1-ol, trans- (5.44%), dodecanal (4.76%), trans-tetradec-2-enal (3.14%), sedanolide (3.02), and thymol (3.01%). DPPH-induced free radical and ferric chloride scavenging assays demonstrated low antioxidant effects of CEO, and the antioxidant activity was observed at a high CEO concentration. The antimicrobial activity of CEO was assessed against 5 microorganisms (bacteria and fungi) by using well diffusion methods; CEO was found to possess excellent antimicrobial activity against all microorganisms, except Escherichia coli. Moreover, CEO demonstrated strong anti-inflammatory activity against egg albumin- and trypsin-induced inflammation.ConclusionThe essential oil extracted from C. sativum chemotype grown in Al-Kharj region of Saudi Arabia possesses low antioxidant potential, superior antimicrobial activity, and outstanding anti-inflammatory effects.     

The seroprevalence of SARS-CoV-2 IgG antibodies among asymptomatic blood donors in Saudi Arabia

BackgroundIn late 2019, cases of severe pneumonia with unidentified etiology began to emerge in Wuhan, China, before progressively spreading first nationally and then globally.The current study sought to investigate the seroprevalence of immunoglobulin G (IgG) antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) among blood donors in Al-Madinah, Saudi Arabia. To our knowledge, this is the first study in Saudi Arabia to screen blood donors who were not known to be previously infected with SARS-CoV-2.MethodsThis study was a cross-sectional study to assess individuals who donated blood to the central blood bank in Al-Madinah between mid-May and mid-July 2020. An enzyme-linked immunosorbent assay (ELISA) was designed and established to detect antibodies directed against the SARS-CoV-2 spike protein in serum samples. A total of 1,212 healthy blood donors participated in this study. The donors were males and met the requirements for blood donation during the COVID-19 pandemic period in Saudi Arabia.ResultsThe SARS-CoV-2 seroprevalence among blood donors in Al-Madinah was 19.31% (n = 234/1212; 95% confidence interval: 17.12%–21.64%). No statistically significant difference was identified in seropositivity according to age. However, significant differences (p < 0.001) were identified according to ABO blood groups, with those with type A blood presenting the highest rate of seropositivity (29.18%) compared with the other blood groups (12.65% for type B, 16.36% for type AB, and 15.11% for type O).ConclusionA high prevalence of SARS-CoV-2 antibodies was detected among blood donors in Al-Madinah, which indicated a high level of exposure to the virus within the population. This further suggested that as high as one-fifth of the population may have acquired innate immunity against the virus.     

The impact of psychological distress on the control of hypertension

Previous research has yielded inconsistent results in the control of essential hypertension. One explanation for response to drug or behavioral therapy may be the patient's psychological status upon entering treatment. Thirty-five borderline hypertensive males entered into a self-management program with biofeedback and cognitive restructuring components. The SCL-90 (Symptom Checklist-90) and the Holmes' Schedule of Recent Events were used to determine if responders and nonresponders could be distinguished prior to treatment on the basis of psychological status. Patients whose hypertension was resistant to treatment (diastolic greater than or equal to 90 mm Hg) reported significantly greater levels of psychological distress and greater life changes than did controlled patients. Pretreatment differences could not be explained by compliance or expectation of success. This study suggests that a relationship exists between psychological distress, life changes and the subsequent control of hypertension; this has implications for treatment selection and design for psychologically distressed individuals.     

Durability of the humoral immune response in recovered COVID-19 patients

BackgroundThe immunological factors involved in protection against the disease caused by SARS-CoV-2 are insufficiently defined and understood. However, previous knowledge pertaining to the related SARS virus and other human coronaviruses may prove useful. Population-based serosurveys measuring anti-SARS-CoV-2 antibodies may provide a pattern for estimating infection degrees and observing the development of the epidemic. In this study, we aimed to investigate the persistence of antibody against the SARS-CoV-2 in recovered patients in Al Madinah region of Saudi Arabia.Materials and methodsA total of 150 recovered COVID-19 patients participated in this study. All the patients tested positive for the presence of SARS-CoV-2 RNA, using qualitative RT-PCR. An ELISA was used to measure anti-Spike (S) IgG antibodies in serum samples and screen for their persistence at various time points post-infection.ResultsThe patients were categorized as asymptomatic (27.3%), mild (28%) and moderate (44.7%) according to the disease severity. Amongst them, 35.3% were females (n = 53) and 64.7% were males (n = 97). Significant anti-S IgG antibody levels were observed among the different groups, with the patients in moderate group exhibiting the highest levels followed by the mild group; while the lowest levels were detected among the asymptomatic. There was a significant positive correlation between the patients’ age and anti-S IgG antibody concentrations (Pearson r = 0.45; p < 0.001).ConclusionOur findings provide a solid evidence to support the use of an anti-S IgG ELISA as a diagnostic tool to indicate SARS-CoV-2 infection. IgG seropositivity was sustained in recovered patients up to a hundred days' post-infection, the latest time point for antibody measurement in our study. Ours is the first report in Saudi Arabia to investigate the durability of humoral immune response in recovered COVID-19 patients.     

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.     

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.     

A Nubian Complex Site from Central Arabia: Implications for Levallois Taxonomy and Human Dispersals during the Upper Pleistocene

Archaeological survey undertaken in central Saudi Arabia has revealed 29 surface sites attributed to the Arabian Middle Paleolithic based on the presence of Levallois blank production methods. Technological analyses on cores retrieved from Al-Kharj 22 have revealed specific reduction modalities used to produce flakes with predetermined shapes. The identified modalities, which are anchored within the greater Levallois concept of core convexity preparation and exploitation, correspond with those utilized during the Middle Stone Age Nubian Complex of northeast Africa and southern Arabia. The discovery of Nubian technology at the Al-Kharj 22 site represents the first appearance of this blank production method in central Arabia. Here we demonstrate how a rigorous use of technological and taxonomic analysis may enable intra-regional comparisons across the Arabian Peninsula. The discovery of Al-Kharj 22 increases the complexity of the Arabian Middle Paleolithic archaeological record and suggests new dynamics of population movements between the southern and central regions of the Peninsula. This study also addresses the dichotomy within Nubian core typology (Types 1 and 2), which was originally defined for African assemblages.     

Preference of sweeteners among Saudi diabetes patients from a tertiary health care centre in Riyadh,Saudi Arabia

BackgroundChoice of sweetening options can influence glyceamic control among patients with diabetes. This study aims to investigate the preference of added sweeteners for Saudi patients with diabetes, factors associated with the choice of sweeteners and the attitude of the patients towards the use of artificial sweeteners.MethodsThis was a cross-sectional study conducted at King Saud University Medical City in Riyadh, Saudi Arabia and targeting Saudi patients with type 2 diabetes mellitus. Data was collected via personal interviews accessing medical records of interviewed patients. Patients were asked about consumption of sweeteners and types of consumed soft drinks on daily basis. Bi-variate analysis of the associations between choice of sweeteners and patients characteristics was performed and followed by binary logistic regression to adjust for potential confounders such as age, gender, and education level.ResultsA total of 302 Saudi diabetic patients were recruited in this investigation. Among this sample, frequency of patients reporting weekly consumption of white sugar was the highest (57%), followed by honey (26%) and artificial sweeteners (12% for powder form and 10.5% for tablets). Consumption of white sugar was significantly more frequent among patients with higher level of Body Mass Index (BMI) (P value < 0.05). The frequency of using honey was higher among females while consumption of either sugared or low calorie soft drinks was significantly higher among male patients (P values < 0.05). Upon asking the patients about their attitude towards artificial sweeteners, only 25% of the sample agreed that their use can aid in reduction of caloric intake while 35% of the sample agreed that artificial sweeteners can be harmful to the body.ConclusionsAmong this sample of type 2 diabetes patients, the frequency of white sugar and honey use as a sweetening option is high. These findings generate the need for further research to investigate the effectiveness of health education and nutritional advice among diabetes patients attending similar clinical settings in Saudi Arabia.     

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.     

Intestinal parasitic infection among foreign housemaids in northwestern Saudi Arabia: A cross-sectional study

Owing to Saudi Arabia's high-income economy many Saudi families hire foreign housemaids. However, since the housemaids are potential carriers of intestinal parasites, hiring them increases the risk of transmission to the Saudi community. In this context, this study aimed to evaluate the prevalence of intestinal parasitic infections in foreign housemaids in northwestern Saudi Arabia. Using direct wet mount and concentration by flotation, the stool samples of 169 housemaids were examined, and eleven parasite species, six helminths and five protozoans, were detected. The overall prevalence of intestinal parasitic infection was 20.11% (34/169). Twelve cases were infected with one intestinal helminth, 12 were infected with one intestinal protozoan, and 10 had polyparasitism. The most common intestinal parasites were Cryptosporidium spp. (n = 10), hookworms (n = 7), and T. Trichiura (n = 7). The findings highlight that intestinal parasites present an important public health concern for foreign housemaids in Saudi Arabia. More vigilance is thus required, and periodic follow-up should be exercised throughout foreign housemaids' stay in the country.     

Factors influencing psychological wellbeing of early breast cancer patients

AimThis paper aims to identify factors that influence the psychological wellbeing of patients newly diagnosed with localized breast cancer.BackgroundPsychological wellbeing plays a significant part in the personal experience of patients during their cancer journey. However, despite progress in treatments and outcomes in breast cancer, psychosocial services and emotional support of cancer patients have been given less attention.Materials and methodsData were collected through a retrospective review of 274 charts of women diagnosed with breast cancer between 2012 and 2017 that received care in a single cancer center. Disease specific parameters, social and demographic variables, and Edmonton Symptom Assessment System (ESAS) scores were extracted from the patient charts.ResultsSelf-reported scores of psychological-related symptoms were low (suggesting no or minimal psychological distress) at baseline and remained low in the majority of patients with breast cancer. Pain, depression, anxiety and wellbeing scores of 0–2 were observed in 78.5%, 81.4%, 63.5% and 70.1% of patients, respectively. Higher scores of anxiety at baseline were observed in patients with physical restrictions on the Eastern Cooperative Oncology Group performance status (ECOG PS) (14.9%), current smoking (20.5%) and history of mental illness (19.1%). Increasing scores for pain were observed in older patients during treatment as compared to baseline. Mastectomy was associated with increased scores for wellbeing (worsening wellbeing) as compared to lumpectomy. Of the patients with a history of mental illness (17.3%), 19.1% had more often increased scores for anxiety.ConclusionsThe findings highlight patients that may benefit from additional social and psychological supports at diagnosis and while undergoing treatment.     

Psychological response of firefighters to a chemical fire

Samples of firefighter subjects (n = 80) and a comparison group (n = 15) were contrasted on a number of postincident psychological distress measures in the aftermath of a polyvinyl chloride (PVC) fire. Using a structured, self-administered questionnaire, firefighter subjects were found to be more psychologically distressed on demoralization, specific emotional distress, and perceived threat to physical health. After controlling for baseline characteristics on which subjects and the comparison group differed, these between-group effects remained significant. The three outcome scales, while correlated, measure different components of psychological distress.     

Prehypertension Tsunami: A Decade Follow-Up of an Iranian Adult Population

ObjectivePrehypertension is associated with cardiovascular disease (CVD). There is no study to examine the incidence and risk factors of prehypertension in a sex stratified setting. The aim of this study was to examine the effect modification of sex for different risk factors which predicts the progression from normotension to prehypertension in a Middle East population-based cohort, during a median follow-up of 9.2 years.MethodsA multivariate Cox analysis was performed among 1466 and 2131 Iranian men and women, respectively, who were free of prehypertension, hypertension, CVD and diabetes at baseline and free of incident hypertension without preceding prehypertension at follow-up. Incident prehypertension at follow-up was defined as systolic blood pressure (SBP) of 120–139 mmHg and/or diastolic blood pressure (DBP) of 80–89 mmHg.ResultsOverall, 1440 new cases of prehypertension were identified resulting in an incidence rate of 593/10000 person-years; the corresponding values for women and men were 489/10000 and 764/10000person-years, respectively. There were significant interactions between gender with age, DBP, waist-to-hip-ratio (WHpR) and estimated glomerular filtration rate (eGFR) (all P-values <0.05) in multivariate analysis. Strong associations were found between age, body mass index (BMI) and SBP with incident prehypertension in both genders. However, the effect of DBP and WHpR was significant among women and 2-hour post challenge plasma glucose (2h-PCPG)was an independent risk factor for men. In the sex-adjusted analysis, glomerular hyperfiltration [Hazard ratio (HR) and 95%CI: 1.01 (1.00–1.01), P-value = 0.02], age, BMI, WHpR, SBP and DBP had higher risks while being female [HR (95%CI): 0.81(0.69–0.94), P-value = 0.01] had a lower risk for incident prehypertension.ConclusionAccording to this study results, among Iranian population with high incidence of prehypertension, general adiposity and glomerular hyperfiltration in total, 2h-PCPG in men and central adiposity in women should be emphasized as risk factors for prehypertension.     

Psychological Distress and Coping amongst Higher Education Students: A Mixed Method Enquiry

Background

Psychological distress among higher education students is of global concern. Students on programmes with practicum components such as nursing and teacher education are exposed to additional stressors which may further increase their risk for psychological distress. The ways in which these students cope with distress has potential consequences for their health and academic performance. An in-depth understanding of how nursing/midwifery and teacher education students experience psychological distress and coping is necessary to enable higher education providers to adequately support these students.

Methods

This mixed method study was employed to establish self-reported psychological distress (General Health Questionnaire), coping processes (Ways of Coping Questionnaire) and lifestyle behaviour (Lifestyle Behaviour Questionnaire) of a total sample (n = 1557) of undergraduate nursing/midwifery and teacher education students in one university in Ireland. Individual interviews (n = 59) provided an in-depth understanding of students experiences of psychological distress and coping.

Results

A significant percentage (41.9%) of respondents was psychologically distressed. The factors which contributed to their distress, included study, financial, living and social pressures. Students used varied coping strategies including seeking social support, problem solving and escape avoidance. The positive relationship between elevated psychological distress and escape avoidance behaviours including substance use (alcohol, tobacco and cannabis) and unhealthy diet is of particular concern. Statistically significant relationships were identified between “escape-avoidance” and gender, age, marital status, place of residence, programme/year of study and lifestyle behaviours such as diet, substance use and physical inactivity.

Conclusion

The paper adds to existing research by illuminating the psychological distress experienced by undergraduate nursing/midwifery and teacher education students. It also identifies their distress, maladaptive coping and the relationship to their lifestyle behaviours. The findings can inform strategies to minimise student distress and maladaptive coping during college and in future professional years.     

Identification of Tomato black ring virus from tomato plants grown in greenhouses in Saudi Arabia

A survey was conducted in Al-Kharj governorate, Riyadh region to identify viruses causing variety of virus-like symptoms on tomato plants. A total of 135 samples were collected from symptomatic tomato plants. Symptoms included mottling, deformation, necrosis of leaves and fruits. Eighteen viruses were tested by DAS-ELISA. Tomato black ring virus (TBRV) was the virus of concern as it was not detected in Saudi Arabia before and was detected in 52.6% of the collected samples in this study. RT-PCR was used to confirm detection of TBRV and to sequence the amplified products to determine molecular characteristics of this virus. In the host range test study that was performed using a purified isolate of TBRV, sixteen out of the twenty two tested plants showed symptoms. Brassica oleracea was not infected by this virus. Gel electrophoreses (2% agarose) yielded fragments of 978 bp of coat protein gene of TBRV. Nucleotide sequences of purified RT-PCR products for three TBRV Saudi isolates were deposited in the GenBank with the following accession numbers MT274656, MT274657, and MT274658. These isolates of TBRV indicated a close Phylogenetic relationship of (99–100%) among themselves and with five isolates from Poland (95–98%) but a distant relationship of 85% with isolates from England and Lithuania deposited in the GenBank. This is the first report for detection and molecular characterization of TBRV infecting tomato plants in Saudi Arabia.
