Objective: This study aimed to explore the association between uric acid (UA) and blood pressure (BP) in hypertension treatment and non-treatment groups.Methods: A cross-sectional study with 6,985 individuals from the National Health and Nutrition Examination Survey (NHANES) was performed. Multiple linear regression analysis was performed to explore the relationship of UA and BP in hypertension between the treatment group (n = 5,983) and the non-treatment group (n = 1,002).Results: A significantly negative association was discovered in SBP (β, −0.36 [95% CI, −0.71, −0.01]) and DBP (β, −0.47 [95% CI, −0.69, −0.26]) in the hypertension treatment group. In the hypertension non-treatment group, the associations between UA and BP including SBP, DBP were both an inverted U-shape. The inflection point of SBP and DBP was 7 and 7.5 mg/dl, respectively. For SBP, the association was positively significant (β, 3.11 [95% CI, 1.67, 4.56]) before the inflection point of 7 mg/dl. However, after the inflection point of 7 mg/dl, the association was negative (β, −5.44 [95% CI, −8.6, −2.28]). For DBP, the inflection point was 7.5 mg/dl, and the effect size was positive (β, 1.19 [95% CI, 0.37, 2.01]) before the inflection point. However, after it, the effect size was negative (β, −3.24 [95% CI, −5.72, −0.76]).Conclusion: The association between UA and BP was negative in the hypertension treatment group. In the hypertension non-treatment group, the associations between UA and BP including SBP and DBP were both an inverted U-shape.

Study Participants

In Saudi Arabia, data regarding salt-related knowledge and practices are still lacking. This cross-sectional study aimed to investigate salt-related knowledge and practices and associated factors in Saudi adults. Data on the following variables were collected from 467 participants living in Madinah or Jeddah via face-to-face interviews: demographics, anthropometrics (height and weight), blood pressure (assessed using a digital sphygmomanometer), salt-related knowledge, and practices related to salt intake. Salt-related knowledge and practices were limited among the study participants; however, they were not correlated (rs = 0.10). Multiple linear regression analysis revealed that salt-related practices were negatively associated with sodium intake and positively associated with body mass index (BMI) (p < 0.001 and p = 0.001, respectively), whereas salt-related knowledge was not associated with sodium intake, blood pressure, or BMI. Salt-related knowledge is limited and not linked to practices related to salt intake in Saudi adults. Interventions are needed to increase the accessibility of low-sodium food options and improve practices limiting sodium intake to prevent the occurrence of salt-related diseases among adults in Saudi Arabia.

Utility Evaluation

Purpose. The utility evaluation was an effective method to incorporate all of the contributing variables for multiple diseases into one outcome measure. A cross-sectional study was conducted to assess the utility values associated with varying states of gallstone disease among outpatient clinics participants at a teaching hospital in Taipei, Taiwan.Methods. The utility values were measured by using time trade-off method. A total of 120 outpatient clinics participants (30 subjects with no gallstone disease, 30 subjects with single stone, 30 subjects with multiple stones, and 30 subjects with cholecystectomy) evaluated utility values from January 1, 2006 to December 31, 2006. The diagnosis of gallstone disease was performed by a panel of specialists using ultrasound sonography.Results. The overall mean utility value was0.89±0.13(95% CI: 0.87–0.91) indicating that study participants were willing to trade about 11% (95% CI: 9–13%) of their remaining life in return for being free of gallstone disease perpetually. The significant associated factors of utility values based on the multiple linear regression analysis were older age and different degrees of gallstone disease.Conclusion. Our results found that in addition to older age, multiple stones and cholecystectomy could influence utility values from the patient’s preference-based viewpoint.

Purpose: To analyze the anterior, posterior, and total corneal spherical aberrations (ASA, PSA, and TSA) in patients with Chinese bilateral ectopia lentis (EL).Methods: A cross-sectional study was conducted to evaluate corneal spherical aberration (CSA) using a Pentacam system at the 6-mm optical zone. Axial length, keratometry, astigmatism, and corneal asphericity were also determined.Results: This study included 247 patients (420 eyes) with a mean age of 18.1 years. The values of ASA, PSA, and TSA were 0.136 ± 0.100 μm, −0.118 ± 0.030 μm, and 0.095 ± 0.095 μm, respectively. In the EL patients with Marfan syndrome (MFS), ASA and TSA were significantly lower than in the non-MFS patients (0.126 ± 0.094 μm vs. 0.155 ± 0.107 μm, P = 0.004 for ASA; 0.085 ± 0.091 μm vs. 0.114 ± 0.099 μm, P = 0.003 for TSA), whereas PSA was not significantly different (P = 0.061). The values of ASA and TSA were significantly higher in the patients with EL aged ≥ 40 years old than in younger patients, whereas ASA and PSA were lower in patients aged &lt;10 years old than in older patients (all P &lt; 0.05). In the multiple linear regression analysis, age, keratometry, astigmatism, anterior asphericity, higher-order aberration (HOA), and lower-order aberration (LOA) were positively or negatively correlated with TSA in the patients with EL (r = 0.681, P &lt; 0.001).Conclusions: Corneal spherical aberration was low in the patients with EL especially for MFS and tended to increase with aging. Preoperatively, individual measurement of CSA was necessary for bilateral EL patients with MFS.

The Relationship

Background. Saliva, as a complex biofluid, plays a pivotal role in maintaining oral health and tooth integrity. There has been inconsistent data available on the relationship between salivary parameters and oral health. This study aims to investigate the association between salivary statherin, acidic proline-rich proteins (aPRP), and calcium with oral hygiene status. Methods. One hundred and eighty-eight healthy subjects aged between 18 and 50 years with varying oral hygiene status who gave consent to participate were included in this cross-sectional study. The subjects were recruited from primary oral health care of MAHSA University. Oral hygiene of all the participants was measured using Oral Hygiene Index–Simplified (OHI-S). Stimulated saliva collected using paraffin wax was analyzed for salivary statherin, aPRP, and calcium. The relationship between salivary statherin, aPRP, and calcium levels with OHI-S was assessed using Spearman’s Rank correlation coefficient; the strength of relationship was assessed by multiple linear regression analysis. Results. The study found a weak positive correlation (r = 0.179, p  = 0.014) between salivary statherin and OHI-S; weak negative correlation (r = −0.187, p  = 0.010) between salivary aPRP and OHI-S; and moderate negative correlation between salivary statherin and salivary aPRP levels (r = −0.50, p  < 0.001) which were statistically significant. Conclusion. Poor oral hygiene is associated with increased statherin and reduced aPRP levels in saliva. Thus, these salivary components may have a role in predicting oral hygiene status.

The present study tested whether emotionally burdened parents due to the COVID-19 pandemic might appraise their relationship with their children more negatively. The current cross-sectional study was circulated through social media. A total of 265 respondents took part in the study. Multiple linear regression analysis was used to examine the association between predictor variables and the parent–child relationship. This study’s results report that older fathers with higher levels of COVID-19 related fear are more likely to appraise negatively their relationship with their children. Therefore, this study suggests the need for family-level strategies to address better the psychological aspects related to the pandemic outbreak.

ObjectiveTo quantify psychosocial risk in family caregivers of children with medical complexity using the Psychosocial Assessment Tool (PAT) and to investigate potential contributing sociodemographic factors.DesignCross-sectional study.SettingFamily caregivers completed questionnaires during long-term ventilation and complex care clinic visits at The Hospital for Sick Children, Toronto, Ontario, Canada.PatientsA total of 136 family caregivers of children with medical complexity completed the PAT questionnaires from 30 June 2017 through 23 August 2017.Main outcome measuresMean PAT scores in family caregivers of children with medical complexity. Caregivers were stratified as ‘Universal’ low risk, ‘Targeted’ intermediate risk or ‘Clinical’ high risk. The effect of sociodemographic variables on overall PAT scores was also examined using multiple linear regression analysis. Comparisons with previous paediatric studies were made using T-test statistics.Results136 (103 females (76%)) family caregivers completed the study. Mean PAT score was 1.17 (SD=0.74), indicative of ‘Targeted’ intermediate risk. Sixty-one (45%) caregivers were classified as Universal risk, 60 (44%) as Targeted risk and 15 (11%) as Clinical risk. Multiple linear regression analysis revealed an overall significant model (p=0.04); however, no particular sociodemographic factor was a significant predictor of total PAT scores.ConclusionFamily caregivers of children with medical complexity report PAT scores among the highest of all previously studied paediatric populations. These caregivers experience significant psychosocial risk, demonstrated by larger proportions of caregivers in the highest-risk Clinical category.

AbstractObjectiveTo compare intake estimates, validity and reliability of two summary questions to measure fish consumption with information from a detailed semi-quantitative food-frequency questionnaire (FFQ) on fish consumption.DesignPopulation-based, cross-sectional study. Participants completed an FFQ and provided blood samples for erythrocyte membrane eicosapentaenoic acid (EPA) analysis. Aggregate measures of consumption of fresh/frozen/canned fish (fresh fish) and smoked/salted/dried fish (preserved fish) were generated from the FFQ and were compared with responses to the summary questions regarding intakes of similar items. Both methods were tested for validity, using correlation and linear regression techniques with EPA, and retest reliability.SettingPerth metropolitan area, Western Australia.SubjectsOne hundred and nine healthy volunteers of both sexes, aged 21–75 years.ResultsThe summary fresh fish measure underestimated frequency and grams per week given by the aggregate question by about 50%, while estimates from the summary preserved fish measure were approximately three times that of the aggregate measure. Multiple linear regression analysis suggested that the aggregates accounted for more of the variation in EPA levels, but the difference was minimal. Intra-class correlations confirmed that both methods were reliable.ConclusionsOur study indicates that extensive questioning results in different absolute intakes of fish compared with brief questioning, but does not add any information if ranking individuals according to overall consumption of fish.

Objectives: This study aimed to assess the knowledge and practices of the general public in the Middle Eastern countries during the COVID-19 pandemic. Methods: A cross-sectional study using an online survey was conducted between the 19th of March and the 6th of April 2020 in three Middle Eastern countries (Jordan, Saudi Arabia, and Kuwait) to explore the knowledge and practices of the Middle Eastern population regarding COVID-19. A previously developed questionnaire was adapted and used for this study. Multiple linear regression analysis was used to identify predictors of COVID-19 knowledge. Results: A total of 1208 participants (members of the public) participated from the three countries (Jordan = 389, Saudi Arabia = 433, and Kuwait = 386). The majority of participants (n = 810, 67.2%) were females aged 30 to 49 years (n = 501, 41.5%). Participants had moderate overall COVID-19 knowledge, with a mean (SD) score of 7.93 (±1.72) out of 12 (66.1%). Participants had better knowledge about disease prevention and control (83.0%), whereas the lowest sub-scale scores were for questions about disease transmission routes (43.3%). High education level was an important predictor of greater COVID-19 knowledge scores (p < 0.01). Conclusions: Further public education is needed to address the relatively low level of education regarding the transmission of COVID-19 in the Middle Eastern countries. Policymakers are recommended to develop informative COVID-19 related campaigns that specifically target young people (university students), unemployed individuals, and those with lower levels of education.

OBJECTIVE: It was to evaluate the relationships between fatigue and excessive daytime sleepiness, sleep quality, depression and anxiety. METHODS: This was a cross-sectional study on 98 unselected adult patients with epilepsy (PWE) at a tertiary center. It used clinical-sociodemographic characteristics, fatigue measured by the SF-36 vitality subscale (VsSF-36) and the Epworth Sleepiness Scale, Pittsburgh Sleep Quality Index and Beck Depression and Anxiety Inventories. RESULTS: We observed that our patients presented vitality or fatigue similar to drivers with chronic headaches evaluated in the same city. Fatigue was related to depression, anxiety and sleep quality, but not to daytime sleepiness. A multiple linear regression analysis was conducted and we observed that fatigue was independently correlated with depression and quality of sleep. However, no significant difference was observed regarding seizure frequency or number of antiepileptic drugs. CONCLUSION: Fatigue needs to be studied more in PWE, and its risk factors need to be controlled, along with sleep quality and psychiatric disorders.

Background: There are two kinds living in the world. They are human beings and animals. The human begins of the pre-historic age lived like animals with little knowledge of a system of social advancement. The households in the rural and urban area are facing the difficult situation act spending of fuel consumption. A moderately large amount of the revenue of the households has to be set separately aside for the expenditure on fuel.Methods: This study was a community based cross-sectional study to assess the fuel consumption, 150 households were included in the study.Results: In the study population 75.33% (113) were male and 24.67% (37) were female. Among the study participants 39.33% of the households are using LPG followed by 24% are using firewood were in 20.67% are using electricity and 16% of households are using kerosene. The multiple linear regression analysis were carried out and the results for the coefficient of multiple determination R squared value is 0.420 which implies 42% of the variation in monthly expenditure of fuel due to the variations in the concerned predictor variables.Conclusions: The study could be conducted in a large a scale over a wider area with a more accurate sampling procedure. This would give more information on the relation between the fuel consumption, the need for conservation as related to the different income groups and different educational level of the respondents.
