Attitude and Behavior of Parents of Children With Sickle Cell Disease Toward the Disease: An Observational Study in Saudi Arabia.

BACKGROUND: Sickle cell disease (SCD) is a significant hematological disorder affecting populations worldwide, with a notable prevalence in certain regions of Saudi Arabia. Despite extensive screening programs, there is a critical need for improved public health education to enhance understanding and management of SCD. This study examines the relationship between the attitudes and behaviors of parents toward their children's disease and its management. METHODS: We conducted a cross-sectional observational study at the King Fahd Medical Research Center in Jeddah. This research encompassed children aged 5-16 years with SCD and their parents. Comprehensive questionnaires assessed sociodemographic data, attitudes toward SCD, and behavioral responses to the illness and treatment. RESULTS: The study included 66 parents, predominantly in the age range of 30-39 years and earning below 5000 Saudi Riyals, who exhibited varying attitudes towards SCD, with a majority questioning the availability of a cure and expressing caution towards new treatments. Despite a cautious approach to invasive treatments, parents relied on information from healthcare providers. Attitudes towards treatment showed significant differences based on gender and education level, with females and less-educated parents exhibiting more hesitancy towards new treatment and blood transfusions. CONCLUSION: The study indicates that while parents show a positive and proactive attitude toward SCD, there is hesitancy towards new and invasive treatments, reflecting the need for continued educational support. The results underscore the importance of tailored healthcare communication strategies to address the diverse needs of families affected by SCD.

Predisposing Factors and Incidence of Venous Thromboembolism among Hospitalized Patients with Sickle Cell Disease.

Though patients with sickle cell disease (SCD) are at risk of developing venous thromboembolism (VTE), clear estimates of its incidence and predisposing factors in hospitalized SCD patients are not available. Therefore, this issue was addressed to facilitate an early diagnosis and initiate appropriate prophylactic and treatment strategies. A retrospective observational study was conducted on patients with SCD who were admitted to an academic center in Saudi Arabia over a 10-year period. We identified 1054 admissions of 394 patients with SCD. Of the 3% of patients identified with VTE, 50% experienced pulmonary embolism (PE), 34.3% exhibited deep vein thrombosis (DVT), 6.3% exhibited cerebral vein thrombosis, and 9.4% showed other forms of VTE. In pregnant SCD patients, 6.4% developed a VTE event during their hospital admission. Of the risk factors, high white blood cell count, length of stay, and presence of any additional risk factor for VTE was associated significantly with higher risk of VTE. In our study, this risk seems to be much lower, which is likely attributed to the use of VTE prophylactic strategies implemented in our center. Nevertheless, further studies are needed to establish the ideal prophylactic strategy in patients with SCD.

Potential inflammatory targets in the integrative health care of patients with sickle cell disease.

Inflammation plays an integral role in the complications of sickle cell disease (SCD), which can lead to vaso-occlusive crisis and extreme pain. SCD is accompanied by numerous complications, including cardiovascular disease, cognitive decline and endothelial dysfunction, contributing to mortality. As disease severity increases with age, the present study aimed to assess if age is also correlated with a definite pattern of progression of the two inflammatory markers, high-sensitivity C-reactive protein (hsCRP) and total homocysteine (tHCY). The findings of the present study could lead to an improved understanding of the threshold levels of these inflammatory markers and timely interventions to delay complications. In an observational study, levels of hsCRP and tHCY were analyzed in 70 patients (35 male and 35 female patients) with SCD aged between 5 and 16 years. hsCRP levels were in the high-risk range in 64.29% (n=45) of all male and female patients. A sex-wise distribution showed that, of the 35 male patients, 74.28% (n=26) were in the high-risk range, and of the 35 female patients, 54.28% (n=19) were in the high-risk range. An age-wise distribution showed that of the 41 patients in the 5-10-years age group, 70.73% (n=29), were in the high-risk range. In comparison, of the 29 patients in the 11-16-years age group, 55.17% (n=16) were in the high-risk range. tHCY levels were observed to be in the normal range in 98.57% (n=69) of all children, as compared with 1.43% (n=1) in the high-risk range. Furthermore, a sex-wise distribution showed that female patients in the high-risk group of hsCRP had higher concentrations of tHCY as compared with the male patients in that risk group. An age-wise distribution of hsCRP concentration also showed that the risk of CVD in patients in the 11-16-years age group was higher with increased concentrations of tHCY. A weak negative correlation was observed between age and hsCRP concentrations (r-value=-0.280; P=0.026) and a weak positive correlation was detected between tHCY and age (r-value=0.259; P=0.036). In conclusion, the results of the present study indicated that higher levels of hsCRP could be a useful marker in children with SCD, and levels of tHCY may be an adjunct marker as the disease progresses with age.

Omega 3 fatty acids - Potential modulators for oxidative stress and inflammation in the management of sickle cell disease

Abstract Objective Sickle cell disease is characterized by clinical complications resulting in vaso-occlusive crisis with prominent attributes of oxidative stress, inflammation, and pain. Inflammation is an integral part of this disease which further exacerbates the pain during a crisis. Omega-3 fatty acids are known to possess anti-inflammatory and anti-aggregatory properties and assist in diminishing the slow physiological inactivation. Methods A pilot nutritional interventional study was conducted wherein forty-three children with sickle cell disease aged 5-16 years were supplemented with omega-3 fatty acids for a period of six months. Analysis of oxidative stress, as well as inflammatory parameters, was done pre and post-supplementation. Results Increased free oxygen radical transference values depicting free radical generation is enhanced in these patients along with a reduced antioxidant defense, as seen by decreased free oxygen radical defense values. Supplementation with omega-3 fatty acids for a period of six months significantly reduced the inflammatory marker homocysteine in all patients, whereas high sensitive C reactive protein was significantly reduced only in females of the age group 11-16years. Simultaneously a significant reduction in oxidative stress parameters with a concomitant increase of antioxidant defense was observed in all patients. Conclusion The authors' findings suggest the regulatory effects of omega-3 fatty acids as cellular activators in alleviating the complications due to sickle cell disease. Omega-3 fatty acids hold promise as future therapeutic candidates in patients with sickle cell disease.

Approaches Towards Professional Studies and Spare-time Activities Among Preclinical and Clinical Year Medical Students.

Objective This study aims at a recognition of the differences in the study habits, approach to teaching resources, and spare-time activities of medical students in the preclinical and clinical training periods at King Abdulaziz University (KAU) Jeddah, Saudi Arabia (SA). Methods Study sampling was carried out in 2017 at the Faculty of Medicine, KAU, Jeddah, SA. Students from both genders were included and further subdivided to preclinical (2nd and 3rd years) and clinical groups (4th, 5th, and 6th years). Students were asked to respond to an online questionnaire. SPSS-Version 21 (IBM Corp., Armonk, NY, US) was utilized for statistical analysis of the collected data, Results Of the 347/500 (response rate 69.4%) medical students, 85 (24.5%) were from the preclinical students (2nd and 3rd years), and 262 (64.5%) were enrolled in the clinical group (4th to 6th years of MBBS). The majority of students 330 (94.1%) were unmarried, only 17 of them, i.e., 4.9%, were married. Analysis of the data revealed that medical textbooks, essential versions of basic medical books, online resources, and online version of books were used more frequently by the clinical group as compared to the preclinical students. Teacher-provided lecture handouts and lecture notes taken during classes were being equally used by both groups. There was a significant difference in the opinion on the usefulness of different resources between both groups. Students faced difficulty in understanding the English language, observed more in the pre-clinical years as compared to relatively groomed clinical students. The preclinical group could not understand the teaching material in books due to a weaker understanding of the English language. Social media software was used for keeping both groups busy, but clinical students also used social media for academic purposes. More than half of the participants from the preclinical and almost one-third from the clinical years admitted that their teachers recommended them for relevant medical textbooks. An encouraging trend was observed in most preclinical group students: they found teaching modalities, such as problem-based learning (PBL) and other academic activities, as a trigger to promote book reading. Conclusion Our results show that the students in the clinical phase had a more methodical approach to professional studies and a difference in spare-time activities.

Precipitating factors and targeted therapies in combating the perils of sickle cell disease--- A special nutritional consideration.

Nutritional research in sickle cell disease has been the focus in recent times owing to not only specific nutritional deficiencies, but also the improvements associated with less painful episodes. Though hydroxyurea remains the drug of choice, certain adverse health effects on long term supplementation makes room for researches of different compounds. Macro and micro nutrient deficiencies, along with vitamins, play an important role in not only meeting the calorific needs, but also reducing clinical complications and growth abnormalities. Symptoms of hyper protein metabolism, increased cell turnover, increased cardiac output, and appetite suppression due to enhanced cytokine production, might give us leads for better understanding of the mechanisms involved. Different nutritional approaches comprising of traditional herbal therapies, antioxidants, flavonoids, vitamins, minerals etc., reducing oxidative stress and blood aggregation, have been tried out to increase the health potential. Nutritional therapies may also serve complementary to the newer therapies using ozone, hematopoietic stem cell transplantation, antifungal medications, erythropoietin etc. Herein we try to present a holistic picture of the different patho-physiological mechanisms, and nutritional strategies adopted.

Panacea seed "Nigella": A review focusing on regenerative effects for gastric ailments.

Nigella sativa (NS) or black cumin is a dark, thin, and crescent-shaped, seeded shrub belonging to the Ranunculaceae family commonly growing on Mediterranean coasts in Saudi Arabia, northern Africa and Asia. They have amazing curative and therapeutic features that make them one of the most popular, safe, non-detrimental, and cytoprotective medicinal plant that can be used for prevention and treatment of many complicated diseases. Originally, N. sativa was used to treat migraines and allergy, and researches have shown its effectiveness in destroying cancer cells as well. The gastro protective effect of NS oil and its constituents has also been reported earlier; however, the complete perception on etiology and pathogenesis of gastric ulcer is not yet clear. Herein, we attempt to unveil some of the potential mechanisms exhibited by NS in preventing problems related to gastric ulcers. Gastric ailments like ulcers and tumors are the most common disorders of the gastro-intestinal tract in the present day life of the industrialized world. Gastric ulcer being a multifaceted problem exhibits complex etiology and is the fourth most common cause of cancer mortality. Drug interactions and toxicity are the main hindrances in chemotherapy. The existing merits and demerits of modern-day drugs make us turn toward the plant kingdom which may provide a valuable resource of novel potent natural compounds for pharmaceuticals or alternately, as dietary supplements. In this context, the revered phytotherapeutic N. sativa comes as a promising savior in today's times. This review aims to summarize, both the functional and disease-related effects in the area of gastroenterology.

Alzheimer's Disease and Autistic Spectrum Disorder: Is there any Association?

Autism spectrum disorder (ASD) and Alzheimer's disease (AD) are neurodevelopmental and neurodegenerative disorders respectively, with devastating effects not only on the individual but also the society. Collectively, a number of factors contribute to the expression of ASD and AD. It is of utmost curiosity that these disorders express at different stages of life and there is an involvement of certain susceptible genes. This genetic basis makes the background of common associations like memory deficits, cognition changes, demyelination, oxidative stress and inflammation, an integral part of both disorders. Modern technology resulting in genetically modified crops and increase in gadgets emitting electromagnetic frequencies have resulted in enhanced risks for neurological dysfunctions and disorders like ASD and AD. Subsequent advances in the psychological, pharmacological, biochemical and nutritional aspects of the disorders have resulted in the development of newer therapeutic approaches. The common clinical features like language impairment, executive functions, and motor problems have been discussed along with the patho-physiological changes, role of DNA methylation, myelin development, and heavy metals in the expression of these disorders. Psychopharmacological and nutritional approaches towards the reduction and management of risk factors have gained attention from the researchers in recent years. Current major therapies either target the inflammatory pathways or reduce cellular oxidative stress. This contribution focuses on the commonalities of the two disorders.

Unraveling the complex relationship triad between lipids, obesity, and inflammation.

Obesity today stands at the intersection between inflammation and metabolic disorders causing an aberration of immune activity, and resulting in increased risk for diabetes, atherosclerosis, fatty liver, and pulmonary inflammation to name a few. Increases in mortality and morbidity in obesity related inflammation have initiated studies to explore different lipid mediated molecular pathways of attempting resolution that uncover newer therapeutic opportunities of anti-inflammatory components. Majorly the thromboxanes, prostaglandins, leukotrienes, lipoxins, and so forth form the group of lipid mediators influencing inflammation. Of special mention are the omega-6 and omega-3 fatty acids that regulate inflammatory mediators of interest in hepatocytes and adipocytes via the cyclooxygenase and lipoxygenase pathways. They also exhibit profound effects on eicosanoid production. The inflammatory cyclooxygenase pathway arising from arachidonic acid is a critical step in the progression of inflammatory responses. New oxygenated products of omega-3 metabolism, namely, resolvins and protectins, behave as endogenous mediators exhibiting powerful anti-inflammatory and immune-regulatory actions via the peroxisome proliferator-activated receptors (PPARs) and G protein coupled receptors (GPCRs). In this review we attempt to discuss the complex pathways and links between obesity and inflammation particularly in relation to different lipid mediators.
