Pregnant women’s use and attitude toward herbal,vitamin, and mineral supplements in an academic tertiary care center,Riyadh, Saudi Arabia

Background

Herbal medicine has been widely utilized by pregnant women despite the limited available evidence regarding the safety and efficacy of that practice. The current available studies, from different countries, estimated that the use of herbal medicine during pregnancy range from 7% up to 96%. The aim of this study is to determine the prevalence, attitude, source of information, and reasoning behind the use of herbal medicine among pregnant women in Saudia Arabia.

Salsola pollen as a predominant cause of respiratory allergies in Kuwait.

BACKGROUND: Respiratory allergies are common in Kuwait, and the role of certain allergens has been previously documented. OBJECTIVE: To evaluate the results of skin prick tests to a range of allergens that were considered relevant to the vegetation surveys and aerobiological studies performed in Kuwait. METHOD: New patients attending our center during August 2002 to February 2003 with asthma or allergic rhinitis underwent skin prick tests to a battery of allergens. RESULTS: A total of 451 patients aged 5 to 60 years (mean age, 29.5 years) were tested. Of these patients, 403 (89.4%) had a positive test result to at least one allergen and were considered allergic. A total of 76.7% of the allergic patients had a positive reaction to Salsola pollen, with a mean wheal diameter of 8.25 mm (median, 8 mm). Chenopodium album was positive in 57.6% and Bermuda grass was positive in 38.2% of the allergic cases. Indoor allergens seemed to play a lesser role than pollens: Dermatophagoides pteronyssinus was positive in only 37.5%, and American and German cockroaches were positive in 33.2% and 22.3%, respectively. All the allergens other than Salsola elicited a mean wheal diameter of less than 6.25 mm (median, < or = 6 mm). CONCLUSIONS: Indoor allergens seem to play a lesser role in respiratory allergies in Kuwait. Most allergic patients become sensitized to pollens; the strongest and most frequent reaction is from Salsola pollen. Salsola imbricata is found growing extensively in most areas of the country, flowering mainly in autumn, when the most common pollen is of the Chenopod-Amaranth type and when most patients with seasonal allergic rhinitis become symptomatic.     

CADASIL in Arabs: clinical and genetic findings

Background  

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is increasingly recognized as an inherited arterial disease leading to a step-wise decline and eventually to dementia. CADASIL is caused by mutations in NOTCH3 epidermal growth factor-like repeat that maps to chromosome 19. CADASIL cases have been identified in most countries of Western and Central Europe, the Americas, Japan, Australia, the Caribbean, South America, Tanzania, Turkey, South Africa and Southeast Asia, but not in Arabs.     

HLA-B*35-Restricted CD8+-T-Cell Epitope in Mycobacterium tuberculosis Rv2903c

Few human CD8(+) T-cell epitopes in mycobacterial antigens have been described to date. Here we have identified a novel HLA-B*35-restricted CD8(+) T-cell epitope in Mycobacterium tuberculosis Rv2903c based on a reverse immunogenetics approach. Peptide-specific CD8 T cells were able to kill M. tuberculosis-infected macrophages and produce gamma interferon and tumor necrosis factor alpha.     

A Study on Sustainable Concrete with Partial Substitution of Cement with Red Mud: A Review

Every year, millions of tons of red mud (RDM) are created across the globe. Its storage is a major environmental issue due to its high basicity and tendency for leaching. This material is often kept in dams, necessitating previous attention to the disposal location, as well as monitoring and maintenance during its useful life. As a result, it is critical to develop an industrial solution capable of consuming large quantities of this substance. Many academics have worked for decades to create different cost-effective methods for using RMD. One of the most cost-effective methods is to use RMD in cement manufacture, which is also an effective approach for large-scale RMD recycling. This article gives an overview of the use of RMD in concrete manufacturing. Other researchers’ backgrounds were considered and examined based on fresh characteristics, mechanical properties, durability, microstructure analysis, and environmental impact analysis. The results show that RMD enhanced the mechanical properties and durability of concrete while reducing its fluidity. Furthermore, by integrating 25% of RDM, the environmental consequences of cumulative energy demand (CED), global warming potential (GWP), and major criteria air pollutants (CO, NO_X, Pb, and SO₂) were minimized. In addition, the review assesses future researcher guidelines for concrete with RDM to improve performance.     

Effect of Date Fruit Consumption on the Glycemic Control of Patients with Type 2 Diabetes: A Randomized Clinical Trial

Objective. Date fruit has been reported to have benefits in type 2 diabetes (T2D), though there is a concern, given the high sugar content, about its effects on glycemic control. Design and Setting. Prospective, interventional, randomized, parallel study. Participants. In total, 79 patients with T2D (39 male and 40 female). Intervention. Participants were randomly allocated to either 60 g date fruit or 60 g raisins daily of the equivalent glycemic index (amount split, given as midmorning and midafternoon snack) for 12 weeks. Main Outcome Measures. The primary outcome was to investigate the effect of date fruit on HbA1c and fasting blood glucose, and their variability, in patients with T2D in comparison to the same glycemic load of raisins. The secondary outcomes were to determine whether date fruit affected cardiovascular risk by measuring fasting lipids, C-reactive protein (CRP), blood pressure, and insulin resistance (IR) as measured by Homeostatic Model Assessment (HOMA-IR). Results. In total, 61 (27 female and 34 male) of 79 patients completed the study. There was no difference between or within groups for HbA1c or HbA1c variability, fasting glucose or glucose variability, insulin resistance (HOMA-IR), insulin sensitivity (HOMA-S), beta cell function (HOMA-B), the disposition index, lipids, systolic (SBP) or diastolic blood pressure (DBP), or C-reactive protein (CRP) (p > 0.05). Conclusion. No improvement in glycemic indices was seen following supplementation of 60 g daily date fruit or raisins, though neither had a deleterious effect on glycemic control over a 12-week period, indicating their safety when consumed in T2D. Additionally, no beneficial therapeutic effects of date fruit on other cardiovascular indices in T2D were seen.     

Prevalence of depression and anxiety among adult patients with multiple sclerosis at Riyadh City,Saudi Arabia

Objectives:To determine the prevalence of depression and anxiety in adult multiple sclerosis patients attending tertiary facilities in Riyadh, Saudi Arabia.Methods:This is a cross-sectional study conducted among MS patients in Riyadh City, Saudi Arabia. A self-administered questionnaire was distributed among MS patients at Prince Sultan Military Medical City in Riyadh, Saudi Arabia between April 2020 and January 2021. The questionnaire consisted of socio-demographic characteristics and the Hospital Anxiety and Depression Scale (HADS). Univariate using Chi-square test and multivariate regression analysis had been performed to determine the factors associated with anxiety and depression among MS patients.Results:A total of 328 MS patients took part in the study. The most prevalent age group was 36–45 years old (38.4%), with over 70% of the participants being females. Anxiety and depression were shown to be prevalent in MS patients at 42.9 percent and 58.8 percent, respectively. According to statistical tests, being less educated and having partial to severe disability was linked to an increased rate of anxiety and depression, whereas being female was more prone to anxiety symptoms but not depression.Conclusion:Depression was more frequent than anxiety. As a result, while assessing psychiatric diseases in the study group, depression/anxiety may be expected to be more frequent amongst those of greater disability.

Multiple sclerosis (MS) is a central nervous system demyelinating disease caused by an immunological response. Depression and anxiety are more common in patients with multiple sclerosis (PWMS) than in the general population, ^1-4 which is a well-known phenomenon. However, we believe that these illnesses are under-recognized in PWMS because several MS symptoms overlap with depression and anxiety, making detection more difficult. Fatigue, sleeplessness, anorexia, memory loss, and concentration problems are all common symptoms of depression, MS, or both. ^5,6 Furthermore, the symptoms of MS might mislead self-report rating scales designed to detect depression and anxiety, resulting in false positives or negatives. ^5,6 Moreover, depression in PWMS can impair their quality of life (QOL), medication adherence, and compliance, worsening their prognosis. ^7-9 Suicidal thoughts and attempts are also common. ^10-13 The hospital Anxiety and Depression Scale is a one-of-a-kind measure for detecting anxiety and depression while taking into account both disorders’ possible confounders, and it has been validated for use in PWMS. ⁶ Depression is a significant mood illness that affects many people. It creates severe symptoms that impact how you feel, think, and handle day-to-day tasks like working, sleeping, and eating. ¹⁴ In PWMS, the lifetime prevalence of depression in up to 50%, ³ compared to 10.8% in the general population. ¹⁵ The cause of depressive disorders in people with MS is unknown. However, it is assumed to be complex, with psychological, social, and neurological aspects - as well as immunologic and genetic factors - all having a part. ¹⁶ Furthermore, depression can have a severe impact on these patients’ health by raising the severity of their symptoms and reducing their compliance with therapy and follow-up, both of which have an impact on their medical costs. ⁹ In addition to a decreased quality of life (QOL), cognitive impairment, and an increased risk of suicide, especially when anxiety is present. ^7,10,11 Furthermore, PWMS have a 10-year lower life expectancy than the general population of the same age. ² Patients, caregivers, and care providers should not underestimate the impact of sadness and anxiety on PWMS. Improved identification, diagnosis, and treatment in medical offices, where people with mood disorders are frequently seen for the first time, can assist to improve these negative outcomes. ¹⁷ Unfortunately, despite convincing evidence of its high incidence, greater influence on prognosis, and quality of life, depression and anxiety are still underdiagnosed and undertreated. ¹³ The goal of this study is to find out how common depression and anxiety are among adult patients with multiple sclerosis in Riyadh, Saudi Arabia. We’ll also see if there’s a link between Hospital Anxiety and Depression Scale (HADS) score and patients’ demographical, socio-educational, and MS-related characteristics, as well as MS duration, Immunomodulatory type, and EDSS scores.
