ABSTRACT
Cognitive dysfunction and behavioral change can be some of the manifestations of cancer, occurring as a part of paraneoplastic neurological syndrome, most commonly in small cell lung cancer. Paraneoplastic limbic encephalitis is the leading cause of cognitive disturbance and abnormal behavior in paraneoplastic syndromes, which is usually autoantibody-mediated. Autoantibodies are the main contributors to the development of cognitive dysfunction and behavioral change in cancer patients, with studies suggesting a higher liability for antibody-positive cancer patients to be affected. Anti-NMDAR and anti-AMPAR are antibodies targeted against surface antigens, manifesting predominantly as memory disturbance, abnormal behavior, psychiatric symptoms, and seizures. Other surface antigen-targeted antibodies include anti-GABA, anti-CASPR2, and anti-LGI1, which were shown to have cognitive function impairment and abnormal behavior as some of the main presentations, predominantly affecting memory. Cognitive deterioration and changes in behavior were also relatively common with some of the intracellular antigen-targeted antibodies, including anti-Hu, anti-SOX1, anti-PCA2, and anti-Zic2. Affected behavior and cognition, however, were reported less commonly in other paraneoplastic antibodies against intracellular antigens (anti-Yo, anti-GAD, anti-Ma2, anti-Ri, anti-CV2, and anti-KLHL11). Our article will provide a comprehensive review of the clinical manifestations of cognitive impairment and behavioral changes among cancer patients who develop paraneoplastic syndrome. Additionally, this review will discuss the role of specific paraneoplastic autoantibodies and the clinical spectrum linked to each separately.
ABSTRACT
Introduction Epilepsy is a neurologic disease that causes a predisposition to recurrent seizure attacks. It affects a large number of people around the world and in Saudi Arabia. Seizures can be a source of distress for both the affected person and those witnessing them. Thus, being able to deliver first aid is important, as it improves safety and decreases the burden of visits to the emergency room that are unnecessary, since many attacks of seizure can be managed in the community. Weak knowledge regarding seizure first aid measures is reported many times across Saudi Arabia, with a high prevalence of misconceptions. Methods This study employed a descriptive cross-sectional design, utilizing a questionnaire-based approach. The data was collected from a sample of 1871 individuals residing in Al-Madinah City, Saudi Arabia. The participants completed a self-administered online questionnaire and ensured anonymity. The questionnaire used in this study was previously validated and used in another study. We used descriptive statistics to summarize the data, and Chi-square test was employed to establish the association between sociodemographic data and knowledge of seizure first aid. Results Most of the participants were females (70.0%, N=1310), and the majority (76.1%, N=1423) fell within the 18-30 age group. A high percentage were single (71.6%, N=1339), college graduates (64.3%, N=1201), and unemployed (58.7%, N=1099). The study results revealed that 31.9% (N=597) had a good knowledge level of epilepsy, while 68.1% (N=1274) had poor knowledge. Nearly half (48.4%, N=905) believed that epilepsy was caused by genetic factors, and 61.4% (N=1149) of the respondents reported loss of consciousness as the most common clinical symptom of epilepsy. With regards to correct action during seizures, 48.0% (N=899) knew to place the patient on their side, and 85.0% (N=1591) thought calling 997 ("the ambulance") was necessary if seizures lasted over five minutes. The study showed a statistically significant association between the level of education, employment, and knowledge of epilepsy first aid management (p=0.001 and p=0.003, respectively). However, no significant associations were found between gender, age, marital status, and knowledge of epilepsy first aid management (p>0.005). Conclusion The study unveiled poor overall epilepsy knowledge among Al-Madinah City residents, with only 31.9% (N=597) demonstrating good knowledge. This indicates the community's limited ability to respond to seizures. Most citizens were unfamiliar with seizure first-aid, lacking the capability to provide assistance. A significant association was found between education, employment, and epilepsy first aid knowledge. Respondents with higher education had better epilepsy knowledge. Attending epilepsy education courses is vital for enhancing overall awareness and readiness to provide seizure first aid.
ABSTRACT
Hematological disorders are common medical ailments constituting an important cause of morbidity and mortality worldwide, which may be managed efficiently using different prophetic medicine remedies as adjuvants to current therapeutics. Prophetic medicine includes the body of knowledge about medicine that has been derived from the deeds, customs (sunnah), ahadith (sayings), actions, and agreements of Prophet Muhammad, peace be upon him. This review article aims at exploring the magnitude of therapeutic benefits of prophetic medicine remedies as adjuvant treatments to many different types of hematological disorders. Herein, we reviewed many published research studies throughout the literature to delineate the potential therapeutic benefits of prophetic remedies on hematological disorders. Several types of hematological disorders may benefit from prophetic medicine remedies that are rich in natural antioxidants that combat oxidative stress-induced harm e.g. nigella sativa, oral honey, camel milk and urine, Ajwa date fruits, olive oil, Zamzam water and figs. Many prophetic medicine remedies were reported to decrease the hematological cytotoxicity effects induced by different chemicals and are beneficial in treating anemias e.g. iron deficiency anemia, sickle cell anemia, thalassemia, coagulopathies and hematological malignancies as leukemia and myeloma. These remedies treat or alleviate the different hematological disorders using different mechanisms e.g. modulating the immune function, treating deficiencies of different substances, protecting against toxins-induced cytotoxicity, decreasing platelets aggregation, suppressing clotting factors activation, exerting antineoplastic effects (enhancing cancer cells cytotoxicity) and inhibiting angiogenesis. Prophetic medicine remedies exert clinically significant therapeutic benefits for treating COVID-19 pandemic, anemia, thrombosis, thalassemia and blood cancers without inducing toxicity or side effects.
ABSTRACT
INTRODUCTION: Chronic disorders commonly require long-term therapies. Medication non-adherence can cause major morbidity and mortality in chronic illness individuals, as well as increase the financial burden on the healthcare system. It is considered that patients who adhere to their treatment may improve their quality of life (QoL). There is a scarcity of updated comprehensive data on medication adherence among Saudi patients with neurological disorders. Therefore, this study aimed to assess the medication adherence status among individuals with neurological conditions and its association with QoL. METHOD: A cross-sectional questionnaire-based study was conducted. The study included subjects individuals who have neurological conditions aged at least 18 from different regions of Saudi Arabia. The questionnaire measured medication adherence by using the 10-item version of the Medication Adherence Report Scale (MARS-10, ©Professor Rob Horne). The QoL was measured by employing validated Euro Quality of Life 5-dimension scale (EQ-5D). RESULTS: A total of 370 participants were included. Respondents aged 18 to 35 years represented 62.4% of the sample. More than half of the participants were females (65.7%). The most frequently reported chronic conditions were migraine (29.2%), epilepsy (20.8%), and multiple sclerosis (20.5%). The reliability of the EQ-5D questionnaire was acceptable (Cronbach's alpha = 0.764). In general, more than half of the participants indicated that had problems due to pain/discomfort (60.3%) and anxiety/depression (62.2%). The most common pattern of non-adherence was taking the medication only when a patient needed it followed by avoiding taking the medication as possible. Non-adherence to medications was less prevalent among participants with epilepsy (68.8%) and multiple sclerosis (65.8%). On the other hand, medication adherence was higher among respondents with migraine compared to participants without the condition (86.1% vs 73.7%, p = 0.009). A significantly lower proportion of participants who had some or extreme problems with self-care were non-adherent to medications compared to those who had no problems (68.1% vs 80.3%, respectively, p = 0.016). Results of the regression analysis showed that participants with epilepsy and multiple sclerosis were less likely to be non-adherence to medications. Furthermore, respondents with moderate and severe problems in self-care were less likely to be non-adherent. CONCLUSION: It was found that more than half of the participants had problems regarding their QoL due to pain/discomfort and anxiety/depression. The most prevalent pattern of non-adherence was taking the medication only when needed. Participants with epilepsy and multiple sclerosis were less likely to be non-adherent to medications. Furthermore, respondents with moderate and severe problems in self-care were less likely to be non-adherent. We recommend serial studies on the issue should be conducted to gather more evidence regarding this topic.
ABSTRACT
Stroke is the most common cause of motor impairment worldwide. Therefore, many factors are being investigated for their predictive and facilitatory effects on recovery of motor function after stroke. Motor recovery can be predicted through several factors, such as clinical assessment, clinical biomarkers, and gene-based variations. As for interventions, many methods are under experimental investigation that aim to improve motor recovery, including different types of pharmacological interventions, non-invasive stimulation, and rehabilitation training by inducing cortical reorganization, neuroplasticity, angiogenesis, changing the levels of neurotransmitters in the brain, and altering the inflammatory and apoptotic processes occurring after stroke. Studies have shown that clinical biomarkers combined with clinical assessment and gene-based variations are reliable factors for predicting motor recovery after stroke. Moreover, different types of interventions such as pharmacological agents (selective serotonin reuptake inhibitors {SSRI}, noradrenaline reuptake inhibitors {NARIs}, levodopa, and amphetamine), non-invasive stimulation, and rehabilitation training have shown significant results in improving functional and motor recovery.
ABSTRACT
Leukemia is the most prevalent type of cancer among children in Saudi Arabia. It has variable clinical presentations and accounts for a large scale of mortality and morbidity. Acute lymphoblastic leukemia (ALL) constituted the majority of pediatric leukemic cases with male gender predisposition. The most common first presentation that patients come with are manifestations of anemia, thrombocytopenia, and fever. Bone pain, fatigue, weight loss, organomegaly, and pale skin are among the commonest manifestations of pediatric leukemia. Childhood ALL and acute myeloid leukemia (AML) clinical manifestations seem to be very similar, even though there're some considerable differences in how common the clinical characteristics are. Chromosomal abnormalities are taken into consideration to determine survival and treatment. PubMed and Google Scholar were searched for the childhood leukemia population in Saudi Arabia. Our review article aims at providing comprehensible and updated statistical data on the different types of leukemia and their clinical presentations in Saudi Arabia.
