RESUMO

OBJECTIVE: Inferior turbinate (IT) hypertrophy-induced chronic nasal obstruction is one of the most common problems in rhinology. However, the histopathological analysis of the hypertrophic IT is unclear. Therefore, this study aimed to identify the histological changes and the most functional areas of the IT to assist otolaryngologists with improving and modifying surgical techniques and minimizing potential complications. METHODS: This prospective, cross-sectional study was conducted to evaluate the contribution of hypertrophic IT to nasal obstruction. For the analysis, a total of 38 adult patients (IT hypertrophy group and non-IT hypertrophy [control] group) were enrolled, and 131 specimens were obtained during the surgical procedures (IT hypertrophy group, endoscopic submucosal turbinoplasty and septoplasty; non-IT hypertrophy group, septoplasty). Intraoperative samples were collected from four sites of the IT to determine the dimensions, composition, and possible pathological changes in each individual site. The samples were analyzed using light microscopy. RESULTS: A comparison of the four sites of the IT in the IT hypertrophy group showed that the posterior end had the highest normal epithelium percentage, and cilia count. This suggests that preserving the functional part of the IT during surgery is crucial. Furthermore, a comparison of both groups in terms of basement membrane thickness and vessel wall thickness (p = 0.005 and p = 0.03, respectively) showed significant differences. CONCLUSION: Our findings can assist otolaryngologists select the most appropriate surgical procedures for IT hypertrophy. In addition, they advocate the importance of preserving the functional part of the IT during surgical intervention to achieve an efficiently working IT and avoid undesirable complications while improving the nasal airway passage. LEVEL OF EVIDENCE: Level 3.

RESUMO

Introduction: Researchers are increasingly favouring the use of biological resources in the synthesis of metallic nanoparticles. This synthesis process is quick and affordable. The current study examined the antibacterial and anticancer effects of silver nanoparticles (AgNPs) derived from the Neurada procumbens plant. Biomolecules derived from natural sources can be used to coat AgNPs to make them biocompatible. Methods: UV-Vis spectroscopy was used to verify the synthesis of AgNPs from Neurada procumbens plant extract, while transmission electron microscopy (TEM), photoluminescence (PL) spectroscopy, dynamic light scattering (DLS), and Fourier transform infrared spectroscopy (FTIR) were used to characterize their morphology, crystalline structure, stability, and coating. Results: UV-visible spectrum of AgNPs shows an absorption peak at 422 nm, indicating the isotropic nature of these nanoparticles. As a result of the emergence of a transmission peak at 804.53 and 615.95 cm-1 in the spectrum of the infrared light emitted by atoms in a sample, FTIR spectroscopy demonstrated that the Ag stretching vibration mode is metal-oxygen (M-O). Electron dispersive X-ray (EDX) spectral analysis shows that elementary silver has a peak at 3 keV. Irradiating the silver surface with electrons, photons, or laser beams triggers the illumination. The emission peak locations have been found between 300 and 550 nm. As a result of DLS analysis, suspended particles showed a bimodal size distribution, with their Z-average particle size being 93.38 nm. Conclusion: The findings showed that the antibacterial action of AgNPs was substantially (p≤0.05) more evident against Gramme-positive strains (S. aureus and B. cereus) than E. coli. The biosynthesis of AgNPs is an environmentally friendly method for making nanostructures that have antimicrobial and anticancer properties.

RESUMO

Background: E-referral systems, streamlining patient access to specialists, have gained global recognition yet lacked a comparative study between internal and external referrals in Saudi Arabia (KSA). Methods: This retrospective study utilized secondary data from the Saudi Medical Appointments and Referrals Centre system. The data covers 2020 and 2021, including socio-demographic data, referral characteristics, and specialties. Logistic regression analysis was used to assess factors associated with external referrals. Results: Out of 645,425 e-referrals from more than 300 hospitals, 19.87% were external. The northern region led with 48.65%. Males were 55%, and those aged 25-64 were 56.68% of referrals. Outpatient clinic referrals comprised 47%, while 61% of referrals were due to a lack of specialty services. Several significant determinants are associated with higher rates of external referral with (p-value <0.001) and a 95% Confidence interval. Younger individuals under 25 exhibit higher referral rates than those aged 25-64. Geographically, compared to the central region, in descending order, there were increasing trends of external referral in the northern, western, and southern regions, respectively (OR = 19.26, OR = 4.48, OR 3.63). External referrals for outpatient departments (OPD) and dialysis services were higher than for routine admissions (OR = 1.38, OR = 1.26). The rate of external referrals due to the lack of available equipment was more predominant than other causes. Furthermore, in descending order, external referrals for organ transplantation and oncology are more frequent than for medical specialties, respectively (OR = 9.39, OR = 4.50). Conclusion: The study reveals trends in e-referrals within the KSA, noting regional differences, demographic factors, and types of specialties regarding external referrals, benefiting the New Model of Care for the 2030 Vision. Findings suggest expanding virtual consultations to reduce external referrals. Strengthening primary care and preventive medicine could also decrease future referrals. Future studies should assess resource distribution, including infrastructure and workforce, to further inform healthcare strategy.

RESUMO

Background: Epidemiological evidence has shown that human papillomavirus (HPV) is the most frequent cause of sexually transmitted infection, and vaccination is an essential measure to prevent associated diseases and complications. This study aimed to assess the HPV vaccine uptake and its associated factors as well as HPV vaccine hesitancy by female healthcare workers (HCWs) in Saudi Arabia. Methods: This online, questionnaire-based, cross-sectional study involved female HCWs in Saudi Arabia between July and October 2022. The study tool included questions about sociodemographic, occupational, and reproductive characteristics, uptake of HPV vaccination, and reasons of hesitancy. Chi-squared and t-tests were used for bivariate analyses, and multivariable logistic regression was used to adjust for confounders. Results: The total number of participants was 1857. Around 20% of HCWs received at least one dose of the HPV vaccine, and around 45% were willing to take it this year. Lower odds of vaccine uptake were reported among older participants and those with a higher level of education. However, nurses, HCWs with a previous HPV infection, those with a family history of cervical cancer, or those with a previous cervical cancer screening test had higher odds of receiving the vaccine. On the other hand, older participants and diploma degree holders were less willing to take the HPV vaccine. Higher odds of willingness were reported in married HCWs, those with a previous HPV infection, those who received a previous HPV vaccine dose, or those who were screened for cervical cancer. Lack of knowledge and some misconceptions were the most reported reasons for hesitancy. Conclusion: Certain factors that affect HCWs personal decisions to take the vaccine were identified. By targeting these issues, epidemiologists, public health officials and women's health care providers can work to increase HPV vaccine uptake and reduce the burden of HPV-related diseases in this population.

RESUMO

Purpose: Epidemiologically, cervical cancer is the fourth most commonly diagnosed cancer among females globally and the third most commonly diagnosed gynecological cancer in Saudi Arabia. Screening is an important measure to prevent it. The current study aimed to assess, epidemiologically, female healthcare workers' (HCWs) utilization of cervical cancer screening services and its association with their beliefs about cervical cancer and the screening test, as well as their personal characteristics. Methods: This cross-sectional study included female HCWs in Saudi Arabia. A predesigned, self-administered survey was used to collect data, and it included questions about sociodemographic and reproductive characteristics, self-utilization of cervical cancer screening services, and the Health Belief Model (HBM) scale. Regression analyses were conducted to identify predictors of cervical cancer screening service utilization. Results: A total of 1857 females participated. The cervical cancer screening test uptake was 24.6% of ever-married females. However, 45% of the participants were willing to have the test. The odds of utilizing a screening were significantly higher among older participants, those with a higher level of education, and those with a higher number of pregnancies. Furthermore, HCWs with a history of HPV infection, cervical cancer in the family, hormonal contraception, or immunocompromised diseases were more likely to have the screening. An increase in the mean scores of the perceived benefits and motives subscales of HBM was associated with an increase in the uptake of screening. However, an increase in perceived barrier scores was significantly associated with a lower likelihood of cervical cancer screening uptake. Conclusion: Low cervical screening uptake and slightly higher intentions to have the test exist among HCWs. Certain personal factors and health beliefs significantly affect the utilization of the screening test. Approaches that target perceived benefits, health motivation, and perceived barriers to improve the screening rates of cervical cancer among HCWs are recommended.

RESUMO

BACKGROUND: Falls are dangerous to the health of older adults and can impact their functional status leading to frailty. The use of potentially inappropriate medications (PIMs) among older adults may lead to adverse health outcomes and increase the risk of falls. Polypharmacy increases the incidence of falls. Beers criteria by the American Geriatric Society is one of the many criteria used to detect PIMs. It assesses the appropriateness of drug prescriptions (i.e., correct dose, duration, and indications) to ensure the safety of these drugs, reducing drug interactions and decreasing the hazards of side effects. This epidemiological study aims to explore the association between polypharmacy and Beers criteria with the risk of falls in the elderly. METHOD: A total of 387 outpatients aged 60 or older were interviewed in person. The patients were recruited from the University Hospital and the Family and Community Medicine Center in Khobar city, Saudi Arabia, between the period of November 2021 to March 2022. All patients were able to walk independently. The survey began by collecting patients' demographics, gathering medication history, and asking three key questions to detect the risk of falls which was developed by the Center of Disease Control (CDC). Polypharmacy (defined as concurrent use of five or more medications) and PIMs (defined as use of one or more medications in the Beers list) were examined against risk of falls in the elderly. Multiple logistic regression analyses were used to estimate adjusted Odds Ratios (ORs). RESULT: A total of 387 patients participated in the study; 62% were male, and most participants belonged to the 60 < 65 years age category (47.80%). Among all patients, 55% had a high risk of falling, and 21% of patients had fell during the past year. Polypharmacy applied to 50.90% of all patients, while Beers criteria positive group applied to 51.42%. Risk of falls and prior falls were associated with polypharmacy both before and after adjustment. CONCLUSION: The results showed a significant association between risk of falls with polypharmacy and PIMs, and more than half of our study population had a high risk of falls. Of those at a higher risk, one out of five had indeed experienced a fall in the last 12 months. Higher rates of falls were associated with older aged patients, lower educational levels, female gender, and cardiovascular medications.

RESUMO

Purpose: A cancer diagnosis is an overwhelming process for both patients and doctors. Many studies have addressed doctors' opinions and knowledge regarding breaking bad news (BBN). However, scarce knowledge exists regarding patients' perspectives for communicating bad news. Therefore, the current study aims to assess cancer patient preferences and satisfaction about BBN. Patients and Methods: This is a mixed methods study consisting of two phases; an in-depth interview and cross-sectional quantitative analysis. Thematic analysis was used for the qualitative data to explore patients' satisfaction and preferences about BBN. For quantitative analyses, the overall satisfaction was calculated as satisfaction percent. Bivariate analyses were performed, and statistical significance was set as p < 0.05. Quality function deployment was used to effectively define patient requirements of highest priority. Results: Thematic analysis revealed two main themes. Theme 1; patients' requirements for BBN and theme 2; patients' reaction at the time of diagnosis with their categories. For the quantitative part, a total of 222 patients responded to the survey, females made up 70% of the sample. Satisfaction score percent ranged from 25.5 to 100%, with a mean of 82.7±11.9%. The most preferred items were mainly concerned with the doctor being honest and encouraging, good listener and interacting giving simple smooth explanations without using medical terms, and empathetic (average score 4.8/5). Also, providing the diagnosis in a calm and private environment (4.7/5). Analysis also found that the requirements for improvement included providing a written summary after receiving the diagnosis and patient perception assessed by the doctor before telling the diagnosis. Conclusion: Communicating bad news effectively is crucial in the management of cancer patients. The process of BBN should be patient-centered, focusing on patients' needs. Thus, the current study has demonstrated the patients' preferences and the requirements, which should be incorporated into BBN protocols.

RESUMO

The COVID-19 pandemic has disrupted cancer care to a certain degree. There is objective evidence that COVID-19 outbreaks are causing substantial emotional distress among cancer patients regardless of their disease severity. This study aims to measure the levels of psychological distress, depression, and pandemic anxiety among cancer patients in Saudi Arabia during the outbreak of COVID-19 and their impact on patients' cancer treatment plans. Methods: This was a cross-sectional study conducted among oncology patients in Saudi Arabia in November of 2020. The levels of stress, depression, and anxiety symptoms during the COVID-19 outbreak were measured using the Questionnaire for Depression and Anxiety (PHQ-4), and patients were classified as depressed/distressed if the total score was 6 and above and classified as not depressed/distressed if they scored less than 6. Results: Among the sampled population, anxiety symptoms and depression were detected in 61.5% and 70.2%, respectively. Statistical analyses revealed that feeling more isolated was significant for anxiety symptoms (p = 0.005), while patients who used institutions as a source of COVID-19 information had significant depression (p = 0.010) compared to patients who accessed information from other sources. In the binary regression model, feeling more isolated than before was 3.208 times more likely to be associated with anxiety symptoms (OR = 3.208; 95% CI = 1.391-7.396; p = 0.006), while those patients who had a support institution as a source of COVID-19 information were 4.2 times more likely to be associated with depression (OR = 4.200; 95% CI = 1.328-13.280; p = 0.015). Conclusion: The COVID-19 pandemic has added to the burden on cancer patients. The increased risk of anxiety symptoms and depression was clearly demonstrated in this study. Feeling isolated had a greater impact on anxiety symptoms, while obtaining COVID-19 information from a patient support institution negatively affected depression.

RESUMO

INTRODUCTION/OBJECTIVES: The prevalence of thyroid disorders is high in Saudi Arabia. Among the disorders, goiter and thyroiditis are the most common and have unique ultrasound (US) features, underscoring the need for US screening for thyroid pathologies. This study aimed to determine the prevalence of thyroiditis and thyroid nodules in patients attending the Family and Community Medicine Center of Imam Abdulrahman Bin Faisal University. METHODS: This registry-based cross-sectional study analyzed laboratory and US data from 240 patients who attended the Family and Community Medicine Center of Imam Abdulrahman Bin Faisal University from January 2020 to December 2021. Abnormalities of the thyroid gland were categorized according to laboratory and US data. Associations between different types of thyroid pathology and clinical and laboratory findings were assessed using appropriate statistical methods. RESULTS: The majority of participants were Saudi women. The prevalence of thyroiditis in the study population was 43%. Approximately 25% of these patients had more than 1 nodule, and fine-needle aspiration biopsy showed that most nodules were benign. Most nodules were found in clinically euthyroid patients. Thyroiditis might be associated with abnormal thyroid function. CONCLUSIONS: Thyroiditis and thyroid nodules were common in our cohort. Vitamin D deficiency, other autoimmune diseases, and a family history of thyroid disorders were associated with thyroiditis and thyroid nodules. US is useful for identifying the type of thyroid disease.

RESUMO

PURPOSE OF THE STUDY: To assess the attitudes and acceptance of cosmetic surgeries and procedures among undergraduate university students in the Eastern Province, Saudi Arabia, as well as the barriers against having cosmetic surgeries and procedures. STUDY DESIGN: A cross-sectional study of undergraduate university students in the Eastern Province, Saudi Arabia, during October 2020. The research instrument included the Attitudes towards Cosmetic Surgery Scale (ACSS), sociodemographic data and perceived barriers towards cosmetic surgeries and procedures. A bivariate analysis was performed followed by a linear regression to account for confounders. RESULTS: A total of 1240 students participated in the study. The mean ACSS for cosmetic surgeries was 3.14 (±1.37 SD), and 3.25 (±1.49 SD) for cosmetic procedures. Older students, students with a history of previous cosmetic surgeries/procedures, and students with engineering specialties had more acceptance scores in both cosmetic surgeries and procedures. On the other hand, men, students belonging to a middle family income and students who perceived themselves to be aware of the risk associated with cosmetic surgeries/procedures had less acceptance scores. The most reported barrier to have cosmetic surgeries and procedures among students was feeling that they do not need it. CONCLUSION: The findings from the current study could help dermatologists, plastic surgeons and adolescent specialists wishing to recognise the rising interest in cosmetic surgeries and procedures in Arabic youth populations, the possible associated factors, as well as the barriers to have these surgeries and procedures. A further qualitative in-depth study to explore the acceptance is suggested.

RESUMO

BACKGROUND: Color vision deficiency (CVD) affects approximately one in 12 men and one in 200 women in the world. It is considered a problem in the medical field since the color is often used as a sign in the practice of medicine, in observational assessment, diagnosis, and follow-up. These conditions make the appreciation of color essential in doctors' lives, thus we aimed at finding the prevalence and predictors of CVD in medical students. MATERIALS AND METHODS: This cross-sectional study included 1115 medical students. A pretested questionnaire consisting of personal data, history of vision problems, familial color vision defect, eye surgery, bad trauma on the head or eyes, drugs taken or chemicals exposed to, other health problems, and whether sufficient amount of Vitamin A is taken was used. This was followed by the screening of the participants for CVD using the Ishihara 15-plates test. RESULTS: A total of 1115 students participated in the study; 52.2% were females and the mean age of the participants was 21.7 years (±1.4). The prevalence of definitive CVD was found to be 2.1%; all of which comprised males. Eighty-seven percent of the affected participants were not aware of their color vision problem. A highly statistically significant association was found between history of vision problems and CVD status (P < 0.008). No association were found for nationality, marital status, family history of CVD, history of eye surgery, and eye trauma. CONCLUSION: The percentage of CVD in the present study is lower than that reported by previous studies done in other countries. Many medical students with CVD remain unaware of their condition. Therefore, we recommend early screening of all school-age children, and proper counseling of medical students with definite CVD to take care of their own health and wellbeing.
