RESUMO

Introduction: Musculoskeletal disorders (MSDs) are rapidly rising in Saudi Arabia, reaching levels similar to those in the Western world. Hence, we aimed to assess the prevalence of neck, shoulder, and lower back pains (musculoskeletal pain, MSP) among students at King Khalid University in Abha, Saudi Arabia. Methods: This cross-sectional study was conducted at King Khalid University in Abha, Saudi Arabia, from March 2023 to August 2023. Inclusion criteria were: university students aged 18 years and older of both sexes who agreed to participate in the study. The modified Nordic questionnaire was used, which comprised three parts. Results: Out of 536 respondents, 337 were women and 199 were men. The average body mass index (BMI) of the study population was 25.3 ± 4.01. In total, 223 (41.60%) had a history of MSDs. Only 232 (43.28%) of the population did regular exercise. According to multiple logistic regression analysis, factors associated with MSDs are mobile device use (with both hands) with a large neck tilt below the horizon line position (OR = 2.276, CI 1.178-4.397, p = 0.014), family history of trauma (OR = 5.450, 95% CI 3.371-8.811, p = 0.000), family history of MSDs (OR = 4.241, 95% CI 2.296-7.835, p = 0.000), coffee consumption (OR = 1.967, CI 1.281-3.020, p = 0.002), and time spent on electronic devices: 1-3 h (OR = 0.252, 95% CI 0.124-0.511, p = 0.0001), 4-6 h (OR = 0.455, 95% CI 0.237-0.873, p = 0.018), and 6-9 h (OR = 0.348, 95% CI 0.184-0.660, p = 0.001). Conclusion: The present study concludes that MSP among university students is high. A history of trauma, a family history of MSDs, the hand and neck position when using electronic devices, the amount of time spent using them, and regular exercise are risk factors that are strongly associated with MSP. There is strong evidence to suggest that increasing physical activity plays a significant role in enhancing the functionality of the musculoskeletal (MSK) system and alleviating pain. It is recommended that universities implement educational programs to raise awareness and health screenings about the impact of device usage on MSK health and the benefits of regular exercise.

RESUMO

Objective: This research aimed to study the knowledge, attitudes, and practices (KAP) toward physical activity (PA) of healthcare students at King Khalid University in Abha, Saudi Arabia. Methods: A prospective web-based cross-sectional study was carried out among healthcare students of King Khalid University from March to May 2024. The questionnaire contained questions on sociodemographic details, five questions about knowledge, eight questions about attitudes, and seven practice-related questions. A multivariable logistic regression analysis was used. Results: Out of the 383 participants, 175 (45.7%) were men and 208 (54.3%) were women. Most of the students, 292 (76.2%), had a body mass index (BMI) of 18.5-24.9. Among the 383, 264 (68.9%) showed good knowledge, 288 (75.2%) had positive attitudes, and 242 (63.2%) had satisfactory PA practice. Most of them, 310 (80.9%), were aware that "regular exercise helps promote strong bones and muscles." Three hundred and fifty-two (91.9%) students believed that individuals who frequently engaged in PA had longer lifespans. More than half of the students (n = 239, 62.4%) engaged in the recommended level of PA. Of the students, 179 (46.8%) agreed that they planned to begin increasing their physical activity during the next 6 months. One hundred and fifty-six (40.7%) stated that they did sports with a high level of intensity for 20 min, three to five times a week, and 175 (45.7%) stated that they did moderate-intensity sports for 30 min, more than five times a week. None of the independent variables had a significant effect on good knowledge levels (p > 0.05). The regression results show being male OR = 0.473 (CI 0.285-0.783 p = 0.004), and being a first-or third-year student OR = 0.329 (CI 0.130-0.832 p = 0.013), OR = 0.276 (CI 0.100-0.762 p = 0.019) has a significant effect on positive attitude levels, while being male OR = 1.945 (CI 1.207-3.135 p = 0.006) and having a BMI between 18.5 and 24.9 OR = 10.101 (CI 2.104-48.49 p = 0.004) has a significant effect on satisfactory practice levels. Conclusion: The majority of participants in our study showed good knowledge and positive attitudes toward PA. A lower number of participants, though still the majority, had satisfactory levels of PA. Health education and health promotion initiatives should maintain and enhance knowledge of the positive effects of PA on health.

RESUMO

For centuries, cannabinoids have been utilized for their medicinal properties, particularly in Asian and South-Asian countries. Cannabis plants, known for their psychoactive and non-psychoactive potential, were historically used for spiritual and remedial healing. However, as cannabis became predominantly a recreational drug, it faced prohibition. Recently, the therapeutic potential of cannabinoids has sparked renewed research interest, extending their use to various medical conditions, including cancer. This review aims to highlight current data on the involvement of cannabinoids in cancer signaling pathways, emphasizing their potential in cancer therapy and the need for further investigation into the underlying mechanisms. A comprehensive literature review was conducted using databases such as PubMed/MedLine, Google Scholar, Web of Science, Scopus, and Embase. The search focused on peer-reviewed articles, review articles, and clinical trials discussing the anticancer properties of cannabinoids. Inclusion criteria included studies in English on the mechanisms of action and clinical efficacy of cannabinoids in cancer. Cannabinoids, including Δ9-THC, CBD, and CBG, exhibit significant anticancer activities such as apoptosis induction, autophagy stimulation, cell cycle arrest, anti-proliferation, anti-angiogenesis, and metastasis inhibition. Clinical trials have demonstrated cannabinoids' efficacy in tumor regression and health improvement in palliative care. However, challenges such as variability in cannabinoid composition, psychoactive effects, regulatory barriers, and lack of standardized dosing remain. Cannabinoids show promising potential as anticancer agents through various mechanisms. Further large-scale, randomized controlled trials are essential to validate these findings and establish standardized therapeutic protocols. Future research should focus on elucidating detailed mechanisms, optimizing dosing, and exploring cannabinoids as primary chemotherapeutic agents.

RESUMO

Matrix Metalloproteinases (MMPs), which are endopeptidase reliant on zinc, are low in embryonic tissues but increases in response to a variety of physiological stimulus and pathological stresses. Neuro-glial cells, endothelial cells, fibroblasts, and leucocytes secrete MMPs, which cleave extracellular matrix proteins in a time-dependent manner. MMPs affect synaptic plasticity and the development of short-term memory by controlling the size, shape, and excitatory synapses' function through the lateral diffusion of receptors. In addition, MMPs influence the Extracellular Matrix proteins in the Peri-Neuronal Net at the Neuro-glial interface, which aids in the establishment of long-term memory. Through modulating neuronal, and glial cells migration, differentiation, Neurogenesis, and survival, MMPs impact brain development in mammals. In adult brains, MMPs play a beneficial role in physiological plasticity, which includes learning, memory consolidation, social interaction, and complex behaviors, by proteolytically altering a wide variety of factors, including growth factors, cytokines, receptors, DNA repair enzymes, and matrix proteins. Additionally, stress, depression, addiction, hepatic encephalopathy, and stroke may all have negative effects on MMPs. In addition to their role in glioblastoma development, MMPs influence neurological diseases such as epilepsy, schizophrenia, autism spectrum disorder, brain damage, pain, neurodegeneration, and Alzheimer's and Parkinson's. To help shed light on the potential of MMPs as a therapeutic target for neurodegenerative diseases, this review summarizes their regulation, mode of action, and participation in brain physiological plasticity and pathological damage. Finally, by employing different MMP-based nanotools and inhibitors, MMPs may also be utilized to map the anatomical and functional connectome of the brain, analyze its secretome, and treat neurodegenerative illnesses.

RESUMO

BACKGROUND: Clozapine has shown great efficacy in treating treatment-resistant schizophrenia, but it is associated with a variety of medication- related safety problems. Despite this, there remains a lack of research on medication errors (MEs) associated with its use. AIM: To characterize the nature and contributory factors of clozapine-related MEs reported from government hospitals and primary care centres in Saudi Arabia (SA). METHOD: A cross-sectional analysis was carried out on MEs related to clozapine use reported to the General Administration of Pharmaceutical Care at the Ministry of Health (MOH) in Saudi Arabia between 2018 and 2022. The data were analysed descriptively to examine the nature and contributory factors of MEs. RESULTS: A total of 1,165 MEs were reported. The majority of reported errors involved patients aged > 18 years old, with 72.2% (n = 841) being male. The central region was found to report errors more frequently (32.3%, n = 376). Pharmacists were reported to detect errors most frequently (59.6%, n = 695). MEs most often occurred in the prescribing stage (77.8%, n = 906), with "missing prescription information" (30.1%, n = 351) being the most frequent finding. The most frequent contributing factor was the lack of policy (33.1%, n = 351). The majority of errors did not reach the patients (92.3%, n = 1,075), and those that did reach patients rarely resulted in harm (0.3%, n = 2). CONCLUSION: This study identified areas for improvement which could expedite the development of remedial interventions to reduce the risk of errors.

RESUMO

Background: Migraine is a disabling disease that poses a significant societal burden. Migraine is a major cause of disability. Migraine is the eighth leading disease-causing disability in the population. Objective: To study the clinical profile and measure the pain and migraine-related disability of patients with all types of migraine using the McGill pain assessment scale and Migraine Disability Assessment (MIDAS) before and after 3 months of effect on the medication. Methods: A Prospective-Cross sectional study was carried out in a multispecialty hospital with male and female patients between 18 and 65 years. The data were collected from the patients directly through the questionnaire of McGill pain assessment scale-short form (SF) and MIDAS, which was provided before and after the medication. Results: There were 165 subjects of which 52 were men and 113 were women. The mean age of all the subjects was 43 years. About 26.06% of the subjects had a family history of headaches. The scores of McGill pain and MIDAS assessment before and after medication were as follows: 0-15 were 30.90% and 73.33%, Score 16-30 were 54.54% and 18.18%, the score of 31-45 were 14.54% and 7.87% of the subjects. MIDAS grade I was 17.57% and 50.90%, Grade II 33.93% and 21.81%, Grade III 30.30% and 15.75% Grade IV 18.18% and 11.51% of the subjects. Discussion: The calculated "t" value between the before and after medication values of McGill and MIDAS by paired 't-test was 13.85 and 17.49 respectively. As the calculated "t" value is more than the table value, the alternate hypothesis is accepted. Conclusion: This study confirms that there is a significant difference in disability levels before and after acute and preventative treatments when measured over 3 months. In addition, the preponderance of females was high, and the functional disability that affects work and social activity associated with migraine is moderate to severe.

RESUMO

Objectives: In postmenopausal states, women may not maintain blood pressure (BP) in the same way as men, even though most women follow their treatment plans and prescriptions more consistently than men. Biological and lifestyle factors influence the progression of hypertension in postmenopausal women (PMW). This study aimed to determine biosocial predictors associated with achieving the target BP in PMW with hypertension. Methods: A prospective observational study was conducted in the General Medicine Department at Karuna Medical College Hospital, Kerala, India. The definition of BP goal attainment was established based on the guidelines outlined by the VIII Joint National Committee 2014 (JNC VIII). Multivariate logistic regression analysis was used to analyse biosocial predictors, such as educational status, employment status, body mass index (BMI), number of children, age at menarche, age at menopause, and number of co-morbidities, associated with BP goal achievement. Results: Of the patients, 56.4% achieved their BP goals on monotherapy and 59.7% achieved it on combination therapy. Level of education [odds ratio (OR) = 1.275, 95% confidence interval (CI): 0.234-7.172], employment status (OR = 0.853, 95% CI: 0.400-1.819), age at menopause (OR = 1.106, 95% CI: 0.881-1.149), number of children (OR = 1.152, 95% CI: 0.771-1.720), BMI (OR = 0.998, 95% CI: 0.929-1.071), and number of co-morbidities (OR = 0.068, 95% CI: 0.088-1.093) did not show a significant relationship, and age at menarche (OR = 1.577, 95% CI: 1.031-2.412) showed a significant association with BP goal attainment among hypertensive postmenopausal women. Conclusion: Half of the hypertensive postmenopausal women did not achieve their BP goals. Interventions are required to expand screening coverage and, under the direction of medical professionals, there should be plans to improve hypertension control and increase awareness of the condition.

RESUMO

Lignans are plant-derived polyphenolic compounds with a plethora of biological applications. Also, regarded as phytoestrogens, the lignans offer a variety of health benefits of which the anti-cancer effects are the most attractive. Honokiol is a lignan isolated from various parts of trees belonging to the genus Magnolia. The bioactivity of honokiol is attributed to its characteristic physical properties, which include small size and the presence of two phenolic groups that may interact with proteins in cell membranes via hydrophobic interactions, aromatic pi orbital co-valency, and hydrogen bonding. The hydrophobicity of honokiol enables its rapid dissolution in lipids and the crossing of physiological barriers, including the blood-brain barrier and cerebrospinal fluid. These factors contribute towards the high bioavailability of honokiol which further support its candidature in medicinal research. Therefore, the anticancer properties of honokiol are of particular interest as many of the contemporary anticancer drugs suffer from bioavailability drawbacks, which necessitates the identification and development of novel candidate molecules directed as anticancer chemotherapeutics. The antioncogenic profile of honokiol also arises from the regulation of various signalling pathways associated with oncogenesis, arresting of the cell cycle by regulation of cyclic proteins, upregulation of epithelial markers and downregulation of mesenchymal markers leading to the inhibition of epithelial-mesenchymal transition, and preventing the metastasis by restricting cell migration and invasion due to the downregulation of matrix-metalloproteinases. In this review, we discuss the anticancer properties of honokiol.

RESUMO

BACKGROUND: Oral health literacy was recognized as important to encouraging oral health and avoiding oral health diseases. It is recognized that socioeconomic conditions are also influential factors in oral health. Therefore, oral health is an important part of individuals' quality of life and general health. OBJECTIVES: This study was conducted to assess oral health literacy (OHL) and oral health-related quality of life (OHRQoL) among undergraduate students studying at university. METHODS: A prospective cross-sectional study was carried out from November to February 2023 among the students of King Khalid University. OHL and OHRQoL were assessed using a Rapid estimate of adult literacy in dentistry-30 (REALD-30) and oral health impact profile (OHIP-14). Further, Pearson's correlation tests were used to measure the correlation between REALD-30 and OHIP-14. RESULTS: Among the 394 completed respondents, the majority were aged >20 years (n = 221; 56.09%), aged <20 years (n = 173; 43.91%), female (n = 324; 82.23%) and male (n = 70; 17.7%). Participants from health-related colleges were (n = 343; 87.06%), and other colleges were (n = 51; 12.94%) *p < .04. Participants brushing frequency once daily were (n = 165; 41.88%) twice or more per day (n = 229; 58.12%) *p < .018. The overall mean REALD-30 score of the participants was 11.76 ± 0.17 indicating low OHL. The higher mean score of OHIP-14 for the following domains physical pain 12.93 ± 0.56, physical disability 12.05 ± 0.72 and psychological disability 12.71 ± 0.76. Oral health impact profile-14 and REALD showed a positive correlation for health-related colleges (r = .314; *p < .002) and other colleges (r = .09; p < .072). However, a significant correlation was observed between REALD-30 and OHIP-14 scores among health-related colleges (p < .05). The current study concluded that self-rated poor oral health is significantly linked with OHIP-14 scores. Furthermore, systematic health education programs such as regular dental check-ups for college students must be arranged to assist in changing the student's everyday life and oral health behaviours.

RESUMO

Cancer is a hard-to-treat disease with a high reoccurrence rate that affects health and lives globally. The condition has a high occurrence rate and is the second leading cause of mortality after cardiovascular disorders. Increased research and more profound knowledge of the mechanisms contributing to the disease's onset and progression have led to drug discovery and development. Various drugs are on the market against cancer; however, the drugs face challenges of chemoresistance. The other major problem is the side effects of these drugs. Therefore, using complementary and additional medicines from natural sources is the best strategy to overcome these issues. The naturally occurring phytochemicals are a vast source of novel drugs against various ailments. The modes of action by which phytochemicals show their anti-cancer effects can be the induction of apoptosis, the onset of cell cycle arrest, kinase inhibition, and the blocking of carcinogens. This review aims to describe different phytochemicals, their classification, the role of phytochemicals as anti-cancer agents, the mode of action of phytochemicals, and their role in various types of cancer.

RESUMO

Objectives: A cross-sectional study was aimed to assess the prevalence of smoking habits among students at King Khalid University (KKU), Abha, KSA. Methods: This was a cross-sectional study using a Modified Fagerstrom Tolerance Questionnaire (mFTQ), online survey was carried out among the students of KKU. This tool uses a five-point Likert scale for all seven questions, except one question on smoking during the first 2 h of the day. Results: The prevalence of smoking among male students was 67% (n = 243) and females 33% (n = 122). Of the current cigarette smokers, 19% had a nicotine dependence score of ≥6 (high), 48% scored 4-6 (moderate) and 33% scored <4 (minimal). Association between mFTQ and the number of cigarettes per day (p < 0.001), first smoke of your cigarettes (p < 0.018), smoking in the morning (p < 0.007), and difficulty refraining from smoking in public areas (p < 0.000). The results of the current study recommend that cigarette smoking habits are a significant risk behavior among young students. The strength of this study signifies that most participants (62%) intend to quit if appropriately supported. Conclusion: According to the findings of the current investigation, smoking was quite common among males. It raises the alarm about the critical need for adequate education to support health education initiatives, discourage teen smoking, and enhance health outcomes for the community.

RESUMO

Aquaporin-4 (AQP4) is the water regulating channel found in the terminal processes of astrocytes in the brain and is implicated in regulating the astrocyte functions, whereas in neuropathologies, AQP4 performs an important role in astrocytosis and release of proinflammatory cytokines. However, several findings have revealed the modulation of the AQP4 water channel in the etiopathogenesis of various neuropsychiatric diseases. In the current article, we have summarized the recent studies and highlighted the implication of astrocytic dysfunction and AQP4 in the etiopathogenesis of depressive disorder. Most of the studies have measured the AQP4 gene or protein expression in the brain regions, particularly the locus coeruleus, choroid plexus, prefrontal cortex, and hippocampus, and found that in these brain regions, AQP4 gene expression decreased on exposure to chronic mild stress. Few studies also measured the peripheral AQP4 mRNA expression in the blood and AQP4 autoantibodies in the blood serum and revealed no change in the depressed patients in comparison with normal individuals.

RESUMO

Cancer accounted for almost ten million deaths worldwide in 2020. Metastasis, characterized by cancer cell invasion to other parts of the body, is the main cause of cancer morbidity and mortality. Therefore, understanding the molecular mechanisms of tumor formation and discovery of potential drug targets are of great importance. Gene editing techniques can be used to find novel drug targets and study molecular mechanisms. In this review, we describe how popular gene-editing methods such as CRISPR/Cas9, TALEN and ZFNs work, and, by comparing them, we demonstrate that CRISPR/Cas9 has superior efficiency and precision. We further provide an overview of the recent applications of CRISPR/Cas9 to cancer research, focusing on the most common cancers such as breast cancer, lung cancer, colorectal cancer, and prostate cancer. We describe how these applications will shape future research and treatment of cancer, and propose new ways to overcome current challenges.

RESUMO

Pyridine derivatives are the most common and significant heterocyclic compounds, which show their fundamental characteristics to various pharmaceutical agents and natural products. Pyridine derivatives possess several pharmacological properties and a broad degree of structural diversity that is most valuable for exploring novel therapeutic agents. These compounds have an extensive range of biological activities such as antifungal, antibacterial, anticancer, anti-obesity, anti-inflammatory, antitubercular, antihypertensive, antineuropathic, antihistaminic, antiviral activities, and antiparasitic. The potent therapeutic properties of pyridine derivatives allow medicinal chemists to synthesize novel and effective chemotherapeutic agents. Consequently, the imperative objective of this comprehensive review is to summarize and investigate the literature regarding recent advancements in pyridine-based heterocycles to treat several kinds of cancer. Furthermore, the performances of pyridine derivatives were compared with some standard drugs, including etoposide, sorafenib, cisplatin, and triclosan, against different cancer cell lines. We hope this study will support the new thoughts to pursue the most active and less toxic rational designs.

RESUMO

Tribulus terrestris saponins (TTS) have been longley used as an overall tonic and recent studies showed they influence inflammatory conditions. We examined the ameliorative effect of a commercial formula of a saponin-rich extract of TT in a model of dietary obesity in female rats focusing on their ability to control the inflammatory burden, insulin resistance (IR), adipokine expression and the related reproductive system pathologies. Female rats were fed with high fat diet (HFD) for 14 weeks to launch diet-induced obesity; they were assigned as: the obese control female rats (OFR) which received no treatment and TTS (5 and 10 mg/kg/day) treated rats; they were compared to a normal rat group. We determined the IR index, serum/tissue inflammatory cytokines, and adipose tissue adipokine expression and examined the secondary ovarian pathologies. Body weight gain, serum triglycerides and IR (>5-fold) in the OFR group were greater than the normal group; TTS lessened these parameters compared with the OFR group. TTS, at 10 mg/kg dose, ameliorated mRNA expression of leptin and visfatin genes in addition to serum inflammatory cytokine levels. Moreover, TTS corrected the hyperprolactinemia and other hormonal disturbances and ameliorated the ovarian pathologies. This study highlighted that the anti-inflammatory properties of TTS helped in alleviation of IR and body weight gain in OFR. Upon correction of obesity manifestations, the gonadal hormone dysregulations and ovarian pathologies were subsequently ameliorated. We can consider TTS as a promising candidate that may alleviate the inflammatory burden, IR and adipokine expression in obesity and hence prevent the secondary gonadal complications in female subjects if appropriate clinical studies are available.

RESUMO

Nifuroxazide is an antidiarrheal medication that has promising anticancer activity against diverse types of tumors. The present study tested the anticancer activity of nifuroxazide against Ehrlich's mammary carcinoma grown in vivo. Furthermore, we investigated the effect of nifuroxazide on IL-6/jak2/STAT3 signaling and the possible impact on tumor angiogenesis. The biological study was supported by molecular docking and bioinformatic predictions for the possible effect of nifuroxazide on this signaling pathway. Female albino mice were injected with Ehrlich carcinoma cells to produce Ehrlich's solid tumors (ESTs). The experimental groups were as follows: EST control, EST + nifuroxazide (5 mg/kg), and EST + nifuroxazide (10 mg/kg). Nifuroxazide was found to reduce tumor masses (730.83 ± 73.19 and 381.42 ± 109.69 mg vs. 1099.5 ± 310.83) and lessen tumor pathologies. Furthermore, nifuroxazide downregulated IL-6, TNF-α, NFk-ß, angiostatin, and Jak2 proteins, and it also reduced tumoral VEGF, as indicated by ELISA and immunohistochemical analysis. Furthermore, nifuroxazide dose-dependently downregulated STAT3 phosphorylation (60% and 30% reductions, respectively). Collectively, the current experiment shed light on the antitumor activity of nifuroxazide against mammary solid carcinoma grown in vivo. The antitumor activity was at least partly mediated by inhibition of IL-6/Jak2/STAT3 signaling that affected angiogenesis (low VEGF and high angiostatin) in the EST. Therefore, nifuroxazide might be a promising antitumor medication if appropriate human studies will be conducted.
