RESUMO

The flu, often known as influenza, is a dangerous public health hazard for the pediatric population. Immunization is essential for decreasing the burden of the disease and avoiding complications related to influenza. However, the immunogenicity, efficacy, and safety of different influenza vaccines in children warrant careful evaluation. The purpose of this narrative review is to give a summary of the existing literature on the immunogenicity, efficacy, and safety of several vaccinations against influenza viruses in children. The review incorporates evidence from a range of studies focusing on the outcomes of interest. Immunogenicity studies have shown that influenza vaccines induce a robust immune response in children, primarily through neutralizing antibodies' formation. However, variations in vaccine composition influence the duration and magnitude of immune responses. Safety is a crucial consideration in pediatric vaccination. In children, influenza vaccinations have generally shown a high safety profile, with mild and temporary side effects being the most common. Vaccinations against influenza have shown a modest level of efficacy in avoiding hospitalizations linked to influenza, laboratory-confirmed influenza infections, and serious consequences in children. Live attenuated vaccines have shown higher effectiveness against matched strains compared to inactivated vaccines. In conclusion, this narrative review highlights that receiving influenza vaccination in children aged six to 47 months is very important. While different vaccines exhibit varying immunogenicity, safety profiles, and effectiveness, they all contribute to reducing the burden of influenza among children. Future research should focus on optimizing vaccine strategies, improving vaccine coverage, and evaluating long-term protection.

RESUMO

Hepatocellular carcinoma (HCC) affects approximately 800,000 individuals globally each year. Despite advancements in HCC treatments, there is still a pressing need to identify new drugs that can combat resistance. One potential option is echinacoside, a natural caffeic acid glycoside with antioxidant, anti-inflammatory, antidepressant, and antidiabetic properties. Therefore, we aimed to investigate the ability of echinacoside to exhibit antitumor activity against HCC in rats through ameliorating hepatic fibrosis and tumor invasion. Rats were given thioacetamide to induce HCC, and some were given 30 mg/kg of echinacoside twice a week for 16 weeks. The liver impairment was assessed by measuring serum α-fetoprotein (AFP) and examining liver sections stained with Masson trichrome or anti-transforming growth factor (TGF)-ß1 antibodies. The hepatic expression of mRNA and protein levels of TGF-ß1, ß-catenin, SMAD4, matrix metalloproteinase-9 (MMP9), phosphoinositide 3-kinases (PI3K), mammalian target of rapamycin (mTOR), connective tissue growth factor 2 (CCN2), E-Cadherin, platelets derived growth factor (PDGF)-B and fascin were also analyzed. Echinacoside improved the survival rate of rats by decreasing serum AFP and the number of hepatic nodules. Examination of micro-images indicated that echinacoside can reduce fibrosis. It also significantly decreased the expression of TGF-ß1, ß-catenin, SMAD4, MMP9, PI3K, mTOR, CCN2, PDGF-B, and fascin while enhancing the expression of E-Cadherin. In conclusion, echinacoside exhibits a protective effect against HCC by increasing survival rates and decreasing tumor growth. It also acts as an inhibitor of the hepatic tissue fibrosis pathway by reducing the expression of TGF-ß1, ß-catenin, SMAD4, PI3K, CCN2, PDGF-B and mTOR. Additionally, it prevents tumor invasion by suppressing MMP9 and fascin, and increasing the expression of E-Cadherin.

RESUMO

BACKGROUND: Smoking is a well-known risk factor for various health problems, including oral cancer. P16 and P53 proteins are involved in cell cycle regulation and proliferation, and their expression levels can provide insights into cellular health. OBJECTIVE: This study aims to evaluate the cellular changes and immunohistochemistry expression of p53 and p16 in the oral mucosa among Saudi smokers. METHOD: In a cross-sectional study obtained by scraping the buccal mucosa, 1000 samples were collected from 2022 to 2023. All of the study's participants were Saudi citizens of both genders. Seven hundred cigarette smokers and 300 nonsmokers made up the controls, using two sampling techniques: initially purposive and then snowball sampling. The materials were subjected to immunohistochemical analysis for P16 and P53 protein overexpression. The samples were scored based on the percentage of positively stained cells and staining intensity. The data were analyzed using SPSS, and categorical variables were identified as frequencies and percentages using the chi-squared test; a value of (P<0.05) was considered significant. RESULT: Cigarette smokers demonstrate significantly higher rates of cytological inflammation, reverse cytological infection, atypia, and binucleated/multinucleated cells compared to nonsmokers, with an overall abnormal result rate of 46% versus 18.7%, respectively (P=0.024). The study found higher P53 and P16 expression among smokers (7.14% and 2.14%, respectively) compared to nonsmokers (0.1% and 0.33%) (P=0.038). No significant differences were observed in P53/P16 expression across age groups (P=0.72) or between male and female participants (P=0.25). CONCLUSION: These findings highlight the detrimental effects of smoking on cellular health and reinforce the importance of smoking cessation in reducing the risk of developing cytological abnormalities and associated diseases. These results highlight the association of smoking with increased biomarker expression, emphasizing its relevance in understanding oral health risks.

RESUMO

Background Breast cancer is the most common female cancer worldwide including in Saudi Arabia. As a result, many cases are diagnosed at an advanced stage, leading to a poor outcome. Understanding risk perception is a significant component of awareness of breast cancer risks. It can be helpful to reduce the mortality of breast cancer via increasing awareness of the risk factors. Objective Our study was designed to assess the level of awareness among women in Saudi Arabia regarding breast cancer, including knowledge about risk factors, symptoms, and the importance of early detection. Methods A cross-sectional study was conducted, and participants were randomly selected. The target population in this study is all women in Saudi Arabia. Data was collected via an online questionnaire. The collected data was analyzed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 21.0, Armonk, NY). Results About 713 women were enrolled in this study. Most of them (69%) were within the age group of 35-45 years old. Age at menarche was found to be 12-13 years old in 313 (43.9%) of the participants and age at first live birth was found to be 20-24 in about 360 (50.5%). The number of population with first-degree relatives that have a history of breast cancer is one relative in 126 (17.7%) of the participants and about 36 (5%) had breast biopsy. About 76 (10.7%) of the participants were considered as having a high risk of breast cancer according to the estimated five-year breast cancer-risk assessment (had a five-year breast cancer risk >1.66%). The mean knowledge score of the participants about breast cancer was found to be 4.62 ± 1.86 out of 8. About 509 (71.4%) of the participants were considered to be having a good level of knowledge about breast cancer. Long-term hormone contraceptive use and older age can increase the chance of developing breast cancer as agreed on by 363 (50.9%) and 287 (40.3%) of the participants respectively. A total of 677 (95%) of the participants mentioned that early detection is important to survive breast cancer. And 639 (89.6%) of the participants think that breast cancer is treatable and about 288 (40.4%) think that the suitable age to start mammography is above 30 years old. Conclusion There is a good general knowledge and awareness about breast cancer among study participants. There were few knowledge gaps regarding the effect of obesity, hormonal contraceptives and older age on the association with breast cancer. About 10% of the participants were found to be having high five-year breast cancer risk.

RESUMO

Pathology is the bridge between basic science and clinical practice. An inadequate perception of pathology leads to an incomplete understanding of diseases, which consequently affects its management. This study aims to identify medical students' perceptions of pathology in medical colleges around Saudi Arabia and use their feedback to improve teaching strategies. A validated online self-structured questionnaire form was distributed to medical students in basic and clinical years, including private and governmental universities in all regions of Saudi Arabia. The study comprised a total of 476 medical students. It revealed that n = 226 (48%) of the participants were not aware of pathologists' roles, and n = 262 (55%) of students reported that the main reason was insufficient exposure to actual pathology practice. A total of n = 209 (44%) students believed the current teaching methods in the basic years were insufficient to provide clear perceptions of pathology. The majority of participants n = 366 (77%) chose practical sessions as the most effective strategy in teaching pathology. Our study demonstrated that medical students require more engagement in laboratories to improve their perception. We suggest that Saudi medical schools need to deliver more comprehensive and practical teaching methods that reflect the actual practice of pathology.

RESUMO

Background Breast cancer (BC) remains a significant health concern, leading to illness and death among women globally. It is essential to detect BC early using imaging techniques that accurately reflect the final pathology, guiding suitable intervention strategies. Objectives This study aimed to evaluate the agreement between radiological findings and histopathological results in BC cases. Methods We conducted a retrospective review of breast core needle biopsies (CNBs) in women over a six-year period (2017-2022) at Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. The pathological diagnoses were compared with the findings from preceding radiological investigations. We also compared the tumour sizes in the resection specimens with their radiological counterparts. Results A total of 641 cases were included in the study. Ultrasound (US), mammography, and magnetic resonance imaging (MRI) yielded diagnostic accuracies of 85%, 77.9%, and 86.9%, respectively. MRI had the highest sensitivity at 72.2%, while US had the lowest at 61%. MRI provided the best agreement with the final resected tumor size. By contrast, mammography tended to overestimate the size (41.9%), and US most frequently underestimated it (67.7%). The connection between basal-like molecular subtypes and the Breast Imaging Reporting and Data System (BIRADS)-5 classifications was only statistically significant for MRI (p = 0.04). The luminal subtype was more likely to show speculation in mammography. Meanwhile, BIRADS-4 revealed a considerable number of benign pathologies across all the three modalities. Conclusions MRI demonstrated the highest accuracy, sensitivity, specificity, and positive predictive value (PPV) for diagnosing and estimating the tumor size. Mammography outperformed US in terms of sensitivity and yielded the highest negative predictive value (NPV). US, meanwhile, offered superior specificity, PPV, and accuracy. Therefore, combining these diagnostic methods could yield significant benefits.

RESUMO

Background The gram-negative anaerobe Clostridium difficile is the main infectious cause of pseudomembranous colitis and infectious diarrhea in hospitalized patients. Inflammatory bowel disease (IBD) patients have been proven to have higher rates of Clostridium difficile infection (CDI). Antibiotic use is the most well-known of the several risk factors for CDI. A few more are advanced age, previous hospitalization, increased severity of an underlying illness, gastrointestinal surgery, and proton pump inhibitors. This study aimed to find out which factors predict CDI in IBD patients at King Abdulaziz University Hospital in Jeddah. Methods We conducted a retrospective cohort study of all inflammatory bowel disease patients who developed CDI with a total sample of 602 patients from 2009 through 2022 at King Abdulaziz University in Jeddah, Saudi Arabia. We identified the clinical data of patients diagnosed with CDI and admitted to the hospital for either diagnosis or follow-up, and we measured the frequencies and percentages as qualitative data and the mean ( standard deviation) as quantitative variables. A chi-square test was used to estimate the correlation between Clostridium difficile infections and multiple factors, including a history of previous hospitalizations, recent flares, intestinal manifestations, extraintestinal manifestations, comorbidities, and IBD medications. Meanwhile, independent t-tests were performed to analyze the continuous variables. Results Out of 602 IBD patients, 53 patients (8.8%) had a confirmed CDI test using an immunoassay for Clostridium difficile toxins A and B. Most of the patients were female and nonsmokers. Regarding colonic involvement, 47 individuals with the disease extending to their large colon also evaluated positive for CDI. Among patients with a positive history of CDI, there were 21 patients with a recent flare-up of fewer than five episodes, five patients had more than five episodes, and the rest did not have any recent flare-ups. Also, IBD patients were significantly at a higher risk for intestinal resection. Conclusion IBD patients are more susceptible to CDI due to flare-ups that require hospitalization and their medications. As a result, clinicians must consider CDI testing in IBD patients who are hospitalized and who are receiving medication to ensure early diagnosis and therapy.

RESUMO

Background Weaning is a complex procedure that gradually introduces complementary foods to the baby's diet. Solid food should be started between the ages of 6 and 12 months. Weaning is a challenging and crucial stage in an infant's development. Extreme caution should be used during weaning an infant because delaying it can cause issues like sluggish growth, difficulties feeding, malnutrition, and iron deficiency. Objective The current study aims to determine the impact of delayed or early weaning practices on the nutritional status of preschool children in Saudi Arabia. Data was gathered about the time of complementary food introduction, preferred foods in the initial stages, and a child's health compared to those practices.  Methodology By convenient sampling, a cross-sectional study was conducted to gather data from 385 parents of Saudi children at preschool age. Questionnaires were shared online. Data were recorded and analyzed on IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp. Descriptive analysis and multivariate ANOVA (MANOVA) tests were performed. Results Only 6.23% of the infants were introduced to complimentary food at optimal age (6 to 12 months), whereas 85% were found to have delayed weaning. As per the BMI, 74.4% of preschool children were severely underweight, 53.6% of infants consumed pureed vegetables early during weaning, and 64% of infants were introduced to eggs and cheese within the first year of life. The timing, pattern, and food items of weaning had a significant (p<0.05) impact on general physical health, as 48.8% of children had pale skin, 46.9% felt tired, 36.5% had swollen joints, and 42% complained of itching and an upset stomach. Conclusion This study couldn't define the direction of significance. Further studies can be done on a larger scale where biochemical tests, and screening can be done on children to find if any significant health problem is prevailing, and the direction of association can be defined.

RESUMO

Introduction Herpes zoster (HZ) is a viral infection that occurs due to the reactivation of the varicella-zoster virus (VZV). Reactivation of the latent virus causes a painful dermatomal rash that is typical in HZ, which is frequently accompanied by post-herpetic neuralgia (PHN). Although HZ negatively impacts individuals' quality of life, vaccination has been shown to reduce the incidence of HZ and PHN and reduce the severity of the disease in the event of a breakthrough. Nonetheless, several studies have shown a low level of knowledge and poor practices regarding HZ and its vaccine. However, only two studies on this issue have been conducted in the Middle East. This study aimed to assess the level of knowledge, attitudes, and practices toward HZ vaccinations among the Saudi population aged 50 years and older. Methods A cross-sectional observational study was conducted from December 2022 to July 2023 involving citizens aged 50 years and older in Saudi Arabia. Data were collected using an online, validated, close-ended structured questionnaire distributed through social media. Linear regression analysis was used to assess independent predictors of knowledge regarding HZ, knowledge regarding the HZ vaccine, and attitudes toward HZ. Categorical variables were dummy-coded. Binary logistic regression was used to assess factors associated with the willingness to receive the HZ vaccine. Results A total of 368 respondents completed the questionnaire. The mean knowledge scores (%) regarding HZ and its vaccine were 28.6% and 37.1%, respectively. While 51.6% (n = 190) claimed to be aware of the HZ vaccine, only 31.6% (n = 60) had a knowledge score of 80% or higher. Multivariate analysis showed that knowledge was positively associated with female gender, prior chickenpox infection, and higher education. Only 54.4% of the respondents were willing to get the HZ vaccine, and 28.8% were willing to pay out of pocket for the HZ vaccine. Conclusion The results suggest that educational campaigns on HZ and its vaccine targeting at-risk groups are required to raise awareness and increase the public's knowledge. Additionally, healthcare personnel's recommendation of the HZ vaccine to the target population should be encouraged, as it is an important factor in vaccine acceptability.

RESUMO

BACKGROUND: Pregnant women are regarded as a unique group due to the distinct immunological condition that pregnancy produces, which makes pregnant women more susceptible to respiratory infections like coronavirus disease 2019 (COVID-19) and its consequences. During pregnancy, many viral infections have been recognized to increase the risk of adverse obstetrical outcomes such as preterm delivery. The purpose of this study was to investigate the effects of COVID-19 infection on preterm birth in pregnant women in the Al-Qassim region of Saudi Arabia. METHODS:  This retrospective cohort study was conducted in Saudi Arabia between December 2019 to October 2021. The target subjects were pregnant women with live singleton gestations who underwent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) testing for COVID-19 infection during their delivery hospitalization. Data gathered included patient demographic information, clinical characteristics, and pregnancy outcomes. Data were analyzed using R version 4.1.1 (R Core Team (2021); R Foundation for Statistical Computing, Vienna, Austria). RESULTS:  A total of 381 pregnant women were included. The median maternal age of women was 31.0 years (IQR: 27.0, 35.0) and the median BMI value was 30.5 kg/m2 (IQR: 26.9, 34.8). The most common comorbidities were diabetes (7.1%) and asthma (4.5%). A known history of preterm birth was prevalent among 2.9%. Of the participants, 13.6% had a prenatal COVID-19 infection, of whom 57.7% had their infections resolved. The prevalence of positive PCR testing was 13.6%. Preterm birth occurred in 46 women (12.1%, 95%CI 9.1-15.9). Preterm birth was significantly associated with having a maternal age of ≥35 years, having high frequencies of parity, and having a past history of preterm birth, as well as having a history of hypertension and diabetes. Preterm birth was not significantly associated with having a confirmed COVID-19 infection at delivery. CONCLUSION: It was shown that preterm birth is evident among women with COVID-19 infection. Preterm birth is significantly associated with old age, multiparity, and a history of preterm delivery. Preterm birth is not significantly associated with having a confirmed COVID-19 infection at delivery. More research regarding infection-related adverse effects is advised and should be highlighted.

RESUMO

Background Diabetes mellitus is a chronic disease that affects millions of people worldwide. Several studies have suggested using stem cells for diabetes treatment. However, there is a lack of research assessing the population's awareness of stem cells. This study aimed to evaluate the level of awareness regarding the use of stem cell therapy for type 2 diabetes mellitus (T2DM). Methodology This study was conducted from December 2021 to April 2022 through an online survey that was distributed electronically via social media platforms. T2DM patients or their care providers who lived in Makkah were included. Patients aged less than 18 years and those with mental disabilities were excluded. Results Of the 316 participants included in the study, 56% were males, 33% had an age range of 46-55 years, and 76% were married. T2DM patients and their caregivers had a moderate level of awareness about stem cell therapy, with caregivers having higher awareness than diabetic patients. A non-significant relationship was found between educational level, income, diabetes control, time of diagnosis, and patients' awareness. However, regarding the decision of treatment, participants aged less than 35 years were highly likely to decide to undergo stem cell treatment compared to other age groups. Conclusions There is a moderate level of awareness about stem cell therapy as a treatment option for T2DM among T2DM patients and caregivers in Makkah. Hence, there is a need to raise awareness by using online and in-person well-organized education programs in Makkah.

RESUMO

BACKGROUND:  Besides their medical career obligations, female physicians traditionally have assumed responsibility for raising families and maintaining the household. Finding an acceptable balance between their career and family life is challenging. OBJECTIVE:  The study aimed to discover the obstacles and the relationship between the barriers/factors with the satisfaction in balancing career and family life. METHODOLOGY:  A cross-sectional study that analyzed data from Saudi female physicians. The study included 165 female physicians from the six Ministry of Health hospitals in Al-Madinah Al-Munawarah; 65 were specialists and consultants, and 100 were general practitioners and residents. The data were collected from October until the end of November 2022 through a semi-structured, self-administered questionnaire gathered by convenience sampling. The data were collected and analyzed with SAS software. RESULTS:  The study's main findings include a satisfaction rate in balancing career and family life among the studied female physicians, which was low at 15.7%. In comparison, female physicians unsatisfied with such balancing were 38.2%. The effect of family responsibilities on career choice was nearly equal, where 50.3% of the studied female physicians affected them. There was a statistically significant difference regarding the satisfaction in balancing career with family life by their specialty; female surgeons and gyn/obs physicians found a higher percentage of unsatisfaction, whereas, among family medicine physicians, the least rate of unsatisfaction was found (P-value < 0.01). At 80% of the studied physicians suggested providing childcare centers as the main solution to their difficulties and obstacles; also, 46.5% suggested taking more days off of maternity leave. Transportation difficulties, however, represented the lowest type of difficulty, 12.7%. CONCLUSION:  The present study has revealed several obstacles facing female physicians that negatively impact relationships with their families.

RESUMO

A hyalinizing trabecular tumor (HTT) of the thyroid gland is a very rare type of tumor. It is usually diagnosed incidentally during the examination for thyroid gland diseases that need thyroidectomy. Here we report a case of HTT in a 60-year-old male patient who presented with anterior neck swelling and underwent total thyroidectomy for a Bethesda category V nodule. The final histologic diagnosis of the left lobe was consistent with a hyalinized trabecular adenoma of the thyroid gland, or paraganglioma-like adenoma. We discuss the clinical picture and diagnostic approach, including the role of fine needle aspiration biopsy, and the pathologic features of HTT, with particular reference to the possible differential diagnosis.

RESUMO

INTRODUCTION: Knee osteoarthritis (KOA) is a degenerative joint disease that progresses over time due to articular cartilage loss. Orthopedic surgeons use plain radiography (X-ray) with an anteroposterior (AP) standing (weight-bearing) view, which is currently considered the gold standard modality, to diagnose KOA. They base this diagnosis on the clinical history and physical examination of the knee joint. However, many previous studies have reported a weak correlation between knee-joint structural abnormalities on X-rays and described pain. Therefore, our study aimed to assess the incompatibility between patients' pain-severity complaints and radiographic findings on standing AP view. No similar study has been recently published in the Middle East. METHODS: 158 participants were selected for the study from King Abdulaziz University Hospital, Jeddah, between March 2022 and August 2022. We graded the patients' AP knee radiographs using the Kellgren-Lawrence (KL) grading scale and the Western Ontario and McMaster Universities Osteoarthritis (WOMAC) index, by which we made phone calls to assess pain severity on a 0-10 pain subscale. RESULTS: We found a significant association between the 0-10 pain subscale and WOMAC questions describing difficulty in sitting (p < 0.05). Comparing KL scores on X-ray on a 0-10 pain subscale, we found a significant association between mild pain and severe radiological findings on X-ray and vice versa. In addition, the comparison between KL scores on X-ray and WOMAC questions describing difficulty in sitting showed a significant association between moderate difficulty in sitting and severe radiological findings and vice versa. CONCLUSION: Our results indicated that there was a significant relationship between mild pain and severe radiological findings on X-rays and vice versa. Additionally, there was a significant relationship, based on the KL score and the WOMAC item that assessed sitting difficulty, between moderate sitting difficulty and severe radiological findings and vice versa. This may suggest that central and peripheral sensitization could be one factor in the causes of pain.

RESUMO

Venous air embolism (VAE) is a rare but potentially lethal condition. It has numerous clinical and physiological causes. We present a case report of a 72-year-old Saudi male, known case of diabetes mellitus (DM), hypertension, and ischemic heart disease. The patient came to the emergency room (ER) complaining of the heaviness of the tongue that resolved spontaneously within a few hours. He underwent percutaneous coronary angiography three months ago. The patient with the previously mentioned neurological symptoms, who had been misdiagnosed as having transient cerebral ischemia, was, after a computerized tomography (CT) scan result, diagnosed with venous air embolism. Venous air embolism can occur in situations other than those in which patients are traditionally thought to be at risk, making diagnosis difficult. Any sudden change in mental status and hemodynamic alterations during minimally invasive procedures should raise the physician's suspicion of VAE. Because VAE is an uncommon complication, few cases have been recorded in Saudi Arabia.

RESUMO

Introduction Glucose-6-phosphate dehydrogenase deficiency (G6PD) is recognized as the most common enzyme disorder globally, impacting over 400 million individuals. The disease is highly prevalent in Saudi Arabia. This study aimed to assess parents' awareness of G6PD in Saudi Arabia and identify misconceptions for targeted educational interventions, aiming to enhance awareness and condition management. Methods A structured online questionnaire was used to gather information from July 18th, 2023, to August 1st, 2023. The survey targeted parents of Saudi children who resided in various regions across Saudi Arabia and collected a total of 531 responses. Data analysis involved descriptive statistics, chi-square tests, and probit regression. A significance level of p<0.05 was employed to interpret the results. Results A statistically significant associations were found among parents with Glucose-6-phosphate dehydrogenase deficiency-deficient children, including gender-related (odd ratio = 2.91, 99% CI: 1.986-4.301), awareness of the genetic link (odd ratio = 2.49, 99% CI: 1.701-3.639), specific medications (odd ratio =1.890, 99% CI: 1.262-2.853), loss of appetite (odd ratio= 0.629, 95% CI: 0.398-0.990), jaundice (odd ratio = 3.01, 99% CI: 1.877-4.983), increased fluid intake (odd ratio= 1.53, 95% CI: 1.091-2.139), receiving blood transfusions (odd ratio = 1.54, 95% CI: 1.101-2.157), seeking online information (odd ratio = 1.92, 99% CI: 1.250-2.940), and consulting healthcare professionals (odd ratio = 3.24, 99% CI: 2.065-5.107). Conclusion Regional disparities in glucose-6-phosphate dehydrogenase deficiency awareness among parents in Saudi Arabia are evident, with the central region demonstrating the highest level of awareness. Understanding glucose-6-phosphate dehydrogenase deficiency risk factors, medication triggers, and clinical symptoms plays a significant role in parental knowledge, emphasizing the need for region-specific education and awareness programs.

RESUMO

Background: In Saudi Arabia, colorectal cancer (CRC) is the most common cancer in males and the third most common cancer in females. The current gold standard for colorectal cancer diagnosis is colonoscopy. Several concerns regarding the balance of ordering colonoscopy procedures for patients presenting with signs and symptoms. There are also several concerns regarding over-ordering the procedure when unnecessary. The current study aimed to evaluate the association between colorectal cancer and colonoscopic conditions in Saudi patients. Methods: A 10-year cross-sectional study was conducted at Alnoor Specialty Hospital, Makkah, over the last ten years. Colonoscopy reports of patients were evaluated to identify the colonoscopy manifestations associated with mass, polyps, and bleeding. Results: The current study evaluated 2158 cases admitted to the hospital for colonoscopic diagnosis. Results indicated that most of the patients were males (55.4%). Additionally, results showed a significant statistical association between tumor and bleeding, polyp, and hemorrhage. Moreover, it highlighted the association between polyps and bleeding, inflammation, and diverticulosis. Conclusion: CRC screening in Saudi Arabia is comprehensive; however, there are a few areas for improvement, including standardization of colorectal cancer pathology reporting to improve the health system's quality. Also, the current study identified conditions that are significantly associated with reported colon polyps and tumors, which could aid in stratifying patients selected for screening via colonoscopy.

RESUMO

BACKGROUND: A global concern about a possible association between COVID-19 vaccines and menstrual disturbance has been raised. Moreover, women who have experienced menstrual changes are worried about the length of the side effects and are hesitant to receive booster doses. Therefore, the aim of this study is to evaluate the impact of the COVID-19 vaccine on all features of the menstrual cycle, including cycle length, amount of bleeding, and pain. METHODOLOGY: We retrospectively analyzed menstrual cycles following at least two doses of COVID-19 vaccines; the cycle changes within the individual pre-vaccination and post-vaccination were compared. All reproductive-aged females from 18 to 45 years who fit the inclusion criteria were included in the study and categorized into five sub-categories based on age to investigate whether certain age groups were most affected. The data were collected through a well-structured self-administered questionnaire. Participants obtained their vaccination information (date, type of vaccine) from Tawakkalna, the official COVID-19 application in the Kingdom of Saudi Arabia. IBM Corp. Released 2019. IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY: IBM Corp was performed in data entry and statistical analysis. Variables were described as frequency and percentage, as all were categorical. To investigate the association between menstrual changes and its possible associated factors, we used the Chi-square test, and the statistical significance was determined at p<0.05. RESULTS: The online questionnaire received responses from a total of 1092 reproductive females. However, out of which, 419 were not fitting into the inclusion criteria. Thus, a total of 673 females were included in the final report. Overall, the changes in the menstrual cycles after both COVID-19 vaccine doses were observed among 46.7%, mainly more menstrual pain in 22.9% following the first dose compared with 21.4% after the second. Menstrual changes were observed among almost two-thirds of women in the age groups 18-22 years (65.2%) and 38-45 years (65.4%) compared with only 43.5% of those in the age group 23-27 years, p<0.001. The Moderna vaccine was associated with the highest rate of menstrual changes (65.4%), whereas Oxford-AstraZeneca was associated with the lowest rate (44.9%), p=0.040. The duration of changes in the cycles after the COVID-19 vaccine (one dose or both) was less than one month among 42.5% of females, whereas it was three months or more among 27.1%. CONCLUSION: The COVID-19 vaccination is associated with a minor and transient change in the menstrual cycle, resulting mainly more menstrual pain and increased bleeding.

RESUMO

Acetaminophen (APAP) is the most extensively used and safest analgesic and antipyretic drug worldwide; however, its toxicity is associated with life-threatening acute liver failure. Cardamom (CARD), a sweet, aromatic, commonly used spice, has several pharmacological actions. In the current study, we tried to explore the chemical composition and the hepato-protective effect of ethanolic aqueous extract of CARD to mitigate APAP-induced hepatic toxicity and elucidate its underlying mechanism of action. MATERIAL AND METHODS: Aqueous CARD extract was subjected to LC-TOF-MS analysis to separate and elucidate some of its components. In vivo animal experiments involved five groups of animals. In the normal and cardamom groups, mice were administered either saline or CARD (200 mg/kg), respectively, orally daily for 16 days. In the APAP group, the animals were administered saline orally daily for 15 days, and on the 16th day, animals were administered APAP (300 mg/kg) IP for the induction of acute hepatic failure. In the CARD 200 + APAP group, mice were administered CARD (200 mg/kg) for 15 days, followed by APAP on the 16th day. RESULTS: The aqueous extract of CARD showed several compounds, belonging to polyphenol, flavonoids, cinnamic acid derivatives and essential oil components. In the in vivo investigations, APAP-induced impaired liver function, several histopathological alterations, oxidative stress and inflammatory and apoptotic status signified severe hepatic failure. Whereas, pretreatment with the CARD extract prior to APAP administration diminished serum levels of the hepatic function test and augmented Nrf2 nucleoprotein and HO-1 and NQO-1. CARD down-regulated MDA, inflammatory mediators (IL-1ß, IL-6, TNF-α and NF-κB) and apoptotic markers (caspase 3 and 9 and Bax) and amplified the activities of SOD, catalase, GSH-Px and GSH-R in hepatic tissue samples. CONCLUSION: CARD extract mitigated the hepatic toxicity induced by APAP. The underlying mechanism of action of such hepato-protective action may be through upregulation of the Nrf2/HO-1/NQO-1 pathway with subsequent alleviation of the oxidative stress, inflammation and apoptosis induced by APAP. Many of the compounds identified in the CARD extract could be attributed to this pharmacological action of the extract.

RESUMO

Extreme ethanol ingestion is associated with developing gastric ulcers. Achillea millefolium (yarrow) is one of the most commonly used herbs with numerous proven pharmacological actions. The goal of the hereby investigation is to explore the gastroprotective action of yarrow essential oil against ethanol-induced gastric ulcers and to reveal the unexplored mechanisms. Rats were distributed into five groups (n = 6); the control group administered 10% Tween 20, orally, for two weeks; the ethanol group administered absolute ethanol (5 mL/kg) to prompt gastric ulcer on the last day of the experiment. Yarrow essential oil 100 or 200 mg/kg + ethanol groups pretreated with yarrow oil (100 or 200 mg/kg, respectively), orally, for two weeks prior to gastric ulcer induction by absolute ethanol. Lanso + ethanol group administered 20 mg/kg lansoprazole, orally, for two weeks prior to gastric ulcer induction by ethanol. Results of the current study showed that ethanol caused several macroscopic and microscopic alterations, amplified lipid peroxidation, pro-inflammatory cytokines, and apoptotic markers, as well as diminished PGE2, NO, and antioxidant enzyme activities. On the other hand, animals pretreated with yarrow essential oil exhibited fewer macroscopic and microscopic modifications, reduced ulcer surface, and increased Alcian blue binding capacity, pH, and pepsin activity. In addition, yarrow essential oil groups exhibited reduced pro-inflammatory cytokines, apoptotic markers, and MDA, restored the PGE2 and NO levels, and recovered the antioxidant enzyme activities. Ethanol escalated Nrf2 and HO-1 expressions, whereas pretreatment of yarrow essential oil caused further intensification in Nrf2 and HO-1. To conclude, the current study suggested yarrow essential oil as a gastroprotective agent against ethanol-induced gastric lesions. This gastroprotective effect could be related to the antioxidant, anti-inflammatory, and anti-apoptotic actions of the essential oil through the instigation of the Nrf2/HO-1 pathway.
