RESUMEN

Background: Identifying and targeting common preventable causes of 30-day hospital readmissions could help improve survival rates and reduce the healthcare burden. Objective: To determine the rate and causes of unplanned hospital return/readmission to the Outpatient Department (OPD) or Emergency Department (ED) within 30 days after discharge following head and neck surgery (HNS) at a tertiary hospital in Western Saudi Arabia. Methods: This retrospective study included all adult patients (aged ≥18 years) who had undergone HNS at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, between January 2015 and December 2022 and returned to the OPD or ED within 30 days of being discharged. Results: Of 1041 patients who had undergone HNS, 84 (8.1%) returned to the hospital within 30 days after discharge: 63 (6.1%) to the OPD and 21 (2.0%) to the ED. A total of 9 (0.9%) patients were readmitted as inpatients, most commonly for infections (33.3%) and neurological symptoms, including weakness and seizures (22.2%). For OPD visits, common causes were wound swelling (25.4%) and neurological symptoms (17.5%). For ED returns, frequent causes were neurological symptoms (23.8%) and surgical site bleeding (19.1%). Readmission was associated with intensive care unit (ICU) admission during the primary hospital stay (P = 0.003) and higher preoperative baseline health burdens when examined using the American Society of Anesthesiology score (P = 0.022), the Cumulative Illness Rating Scale (P = 0.007), and the Charlson Comorbidity Index (CCI) (P = 0.006). Conclusion: The rate of 30-day unplanned hospital return following head and neck surgery was 6.1% and 2.0% through the OPD and the ED, respectively; 0.9% were readmitted as inpatients. Common causes of return included wound swelling, infections, bleeding, and neurological symptoms.

RESUMEN

OBJECTIVES: To assess and compare the Caprini and Padua risk assessment models (RAMs) for predicting venous thromboembolism (VTE) in hospitalized patients. METHODS: We retrospectively reviewed 28 VTE and 450 non-VTE patients hospitalized at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, in 2019. Their baseline medical, demographic, and radiological reports were recorded. We compared Caprini scores (defined at admission) and Padua scores (calculated retrospectively) for their ability to predict VTE. A cumulative risk score was created by adding the individual scores for each risk factor. We also analyzed the sensitivity, specificity, and diagnostic accuracy of the RAM scores. RESULTS: Major differences in risk factors were shown between patients with and without VTE. Previous VTE was significantly associated with a higher risk of VTE (28.6%), as was reduced mobility (57.1%), acute infection (25%), high Caprini score (50%), and high Padua score (64.3%, p<0.05). The sensitivity of the Caprini score (96%) was higher than that of the Padua score (64.3%), as was the specificity (92.1% vs. 46.9%), positive predictive value (93% vs. 7%), and accuracy (94.1% vs. 47.9%). The specificity of the Caprini score was higher than that of the Padua score in Critical Care, Gynecology/Obstetrics, and Surgical departments. The Caprini RAM showed the lowest level of specificity in the medical department. CONCLUSION: The Caprini RAM demonstrated higher sensitivity, specificity, and predictive accuracy than did the Padua RAM and thus distinguished low and high VTE risk in hospitalized patients.

RESUMEN

Traumatic spinal cord injury (TSCI) is one of the catastrophic events in the nervous system that leads to the loss of sensory and motor function of the spinal cord at the site of injury. Considering that several factors such as apoptosis, inflammation, and oxidative stress play a role in the spread of damage caused by trauma, therefore, the treatment should also be based on multifactorial approaches. Currently, we investigated the effects of human menstrual blood stem cells (MenSCs)-derived exosomes in combination with hyperbaric oxygen therapy (HBOT) in the recovery of TSCI in rats. Ninety male mature Sprague-Dawley (SD) rats were planned into five equal groups, including; control group, TSCI group, Exo group (underwent TSCI and received MenSCs -derived exosomes), HBOT group (underwent TSCI and received HBOT), and Exo+HBOT group (underwent TSCI and received MenSCs -derived exosomes plus HBOT). After the behavioral evaluation, tissue samples were obtained for stereological, immunohistochemical, biochemical, and molecular assessments. Our results showed that the numerical density of neurons, the concentrations of antioxidative biomarkers (CAT, GSH, and SOD), and neurological function scores were significantly greater in the treatments group than in the TSCI group, and these changes were more obvious in the Exo+HBOT ones (P<0.05). This is while the numerical densities of apoptotic cells and glial cells, the levels of an oxidative factor (MDA) and proinflammatory cytokines (IL-1ß and TNF-α) were considerably decreased in the treatment groups, specially the Exo+HBOT group, compared to the TSCI group (P<0.05). We conclude that the co-administration of exosomes derived from MenSCs and HBOT has more neuroprotective effects in animals with TSCI.

RESUMEN

Background: Maintaining a stable tear film is crucial for having healthy human and animal vision. Animals are expected to have thicker lipid layers than humans due to living in high-temperature and humid environments. Aim: The study aimed to evaluate the lipid layer patterns (LLPs) in Arabian dogs and rabbits using a non-invasive, practical, and easy-to-use device and compare them to humans with healthy eyes. Methods: The study included 75 domestic Arabian dogs (42 males and 33 females; mean ± SD = 6.1 ± 12.7 months) and 75 rabbits (37 males and 38 females; mean ± SD = 3.1 ± 3.4 months). In addition, 75 individuals with healthy eyes (39 males and 36 females; mean ± SD = 25.7 ± 5.0 years) were included for comparison. EASYTEAR View+ assessed the LLP in each animal's and individual's right eye. Results: The median LLP grades significantly differed between dogs and humans (Mann-Whitney U test, p < 0.001). Similarly, the LLP grades differed significantly between rabbits and humans (Mann-Whitney U test, p < 0.001). No significant difference (Mann-Whitney U test) in the LLP grades between dogs and rabbits was found. The analysis indicated that most dogs had either an A (34.7%) or a B grade (37.3%). Similarly, rabbits had predominantly A or 1 (46.7%) and B (30.7%) grades. On the other hand, humans had predominantly D (53.3%) and E (30.7%) grades. Conclusion: The EASYTEAR View+ has been employed to assess LLP in dogs and rabbits, and the measurements were compared to those of humans with normal ocular health. Dogs and rabbits have thinner lipid layers than healthy humans.

RESUMEN

Introduction Anxiety and depression are prevalent psychological issues among hemodialysis patients, adversely affecting their well-being and treatment response. The study aims to identify the relationship between these mental health concerns and hyperparathyroidism in chronic hemodialysis patients from the Al Baha Region, Kingdom of Saudi Arabia. Methods This retrospective study included 143 chronic hemodialysis patients aged 18-85 years. Monthly laboratory records for parathyroid hormone (PTH) levels and the Hospital Anxiety and Depression Scale (HADS) for mental health assessment were utilized. Demographic information and the primary causes of end-stage renal disease were obtained through patient interviews. Statistical analyses, including chi-square tests, odds ratio, and significance tests, were performed to assess associations. Results Elevated PTH levels were associated with increased anxiety and depression in hemodialysis patients. Patients with PTH levels >400 pg/ml exhibited higher rates of abnormal HADS scores for anxiety and depression than those with PTH levels <400 pg/ml. Gender differences were evident, with women showing a higher predisposition to anxiety disorders and men having depression. Additionally, patients with PTH levels <150 pg/ml had a significantly higher proportion of the "normal" depression score than those with PTH levels >800 pg/ml. Conclusion The study underscores the association between hyperparathyroidism and adverse mental health outcomes in chronic hemodialysis patients. Maintaining optimal PTH levels plays a crucial role in mitigating anxiety and depression. Gender differences in mental health outcomes highlight the need for tailored interventions. Routine mental health assessments, utilizing tools such as the HADS, are important in the comprehensive care of hemodialysis patients.

RESUMEN

BACKGROUND: Adolescents are immersed in a highly advanced technology setting, characterized by extensive availability of personal devices, the internet, and other social media platforms, which greatly impact their mental development. Concerns arise around potential negative consequences, including social isolation, internet addiction, exposure to improper content, depression, cyberbullying, and sleeping difficulty. The impact of social media on the mental well-being of adolescents has emerged as an escalating concern. The continuous exposure to carefully selected content, online harassment, and the expectation to comply with unrealistic standards all contribute to the development of depression and anxiety. This research aims to explore the impact of social media on the mental health of adolescents in the Saudi Arabian context. METHODS: This online cross-sectional study was conducted on Saudis aged 10 to 24 years old who have social media accounts in Saudi Arabia between August and November 2023. Binary logistic regression analysis was conducted to identify factors that make the study participants more likely to be mentally affected by social media. RESULTS: A total of 2856 participants were involved in this study. The most commonly used social media platform by the study participants was Twitter (30.3%). The majority of the study participants (77.4%) reported that they have tried to reduce their social media usage for mental health reasons. The most commonly agreed-upon statements were that "they feel that excessive social media use has negatively affected their sleep patterns," "they often sleep late in the night because of social media usage," and "they check their social media account before they sleep in the night," accounting for 71.0%, 66.1%, and 58.3%, respectively. Overall, the study participants showed a low level of being mentally affected due to social media with a mean score of 7.8 (SD: 3.9) out of 21, which is equal to 37.1%. Older participants (aged 16-24 years) were more prone to be mentally affected due to social media compared to younger ones (aged 10-15 years; p < 0.05). On the other hand, participants who were married, had a middle school education level, or lived in the northern, western, or eastern regions were less likely to be mentally affected due to social media compared to others (p < 0.05). CONCLUSION: The study participants showed a low level of being mentally affected due to social media. Individuals in the 16-24 years age group show a higher susceptibility to mental impacts resulting from social media usage. The primary duty for reducing the potential negative effects of social media should not rest only on parents and caregivers. Advocating for the creation of technology-free zones and fostering in-person friendships among teens could be a beneficial approach that policymakers should support.

RESUMEN

Mpox, a reemerging zoonotic disease caused by the mpox virus, has garnered increasing attention due to its potential for severe clinical manifestations. While the cutaneous and systemic presentations of mpox have been well-documented, its neurological complications have recently emerged as an area of concern. This review provides a brief overview of the neurological aspects of mpox infection, highlighting the key findings and challenges in understanding and managing these complications. Neurological manifestations in mpox patients range from mild symptoms such as headaches and dizziness to more severe conditions, including encephalitis and seizures. The pathogenesis of neurological involvement is not yet fully elucidated but is thought to involve viral dissemination to the central nervous system. This dissemination may occur through haematogenous or neuronal routes, contributing to the diverse clinical spectrum observed. Early recognition and diagnosis of neurological complications in mpox are crucial for implementing appropriate therapeutic interventions and improving patient outcomes.

RESUMEN

Purpose: To evaluate physicians' knowledge of the ABCDE (Airway, Breathing, Circulation, Disability, Exposure) approach components. Methods: A cross-sectional study was conducted in 2023 using an online questionnaire in order to collect data about the knowledge of the ABCDE approach's components among physicians in different specialties in Riyadh, Saudi Arabia. Results: The number of participants were 165 in total and the median knowledge score for all participants was 15.0, with an associated interquartile range (IQR) of 10.0 to 20.0. Intensive Care Medicine had the highest median knowledge score of 19.0 (IQR: 12.0-21.0), followed by Internal Medicine at 17.0 (IQR: 13.0-20.0). Conversely, Cardiology and Anesthesiology showed lower scores, with medians of 8.0 (IQR: 4.0-10.0) and 7.5 (IQR: 4.0-13.5), respectively (p = 0.011). Senior Registrars demonstrated the highest median knowledge score of 20.0 (IQR: 14.0-22.0), while Fellows had the lowest at 8.5 (IQR: 7.0-13.0) (p < 0.001). Practicing for 10 to 15 years and more than 15 years having medians of 20.0 (IQR: 16.0-23.0) and 19.0 (IQR: 17.0-22.0), respectively. However, participants with less experience, working for less than 5 years, had a median score of 12.0 (IQR: 8.5-16.5) (p < 0.001). Conclusion: Knowledge scores of physicians representing various medical specialties found diverse levels regarding the ABCDE approach. Knowledge scores were significantly influenced by the primary area of practice, level of experience, and duration worked in the profession, highlighting the need for tailored training and education across different specialties and career stages. On the other hand, future studies should concentrate on finding new factors that influence practice adherence to the ABCDE approach and tying theoretical knowledge to clinical practice.

RESUMEN

Parkinson's Disease (PD) is a progressive neurodegenerative illness triggered by decreased dopamine secretion. Deep Learning (DL) has gained substantial attention in PD diagnosis research, with an increase in the number of published papers in this discipline. PD detection using DL has presented more promising outcomes as compared with common machine learning approaches. This article aims to conduct a bibliometric analysis and a literature review focusing on the prominent developments taking place in this area. To achieve the target of the study, we retrieved and analyzed the available research papers in the Scopus database. Following that, we conducted a bibliometric analysis to inspect the structure of keywords, authors, and countries in the surveyed studies by providing visual representations of the bibliometric data using VOSviewer software. The study also provides an in-depth review of the literature focusing on different indicators of PD, deployed approaches, and performance metrics. The outcomes indicate the firm development of PD diagnosis using DL approaches over time and a large diversity of studies worldwide. Additionally, the literature review presented a research gap in DL approaches related to incremental learning, particularly in relation to big data analysis.

RESUMEN

BACKGROUND: Lung cancer remains the primary cause of death connected to cancer on a worldwide scale. Obtaining a deep understanding of the knowledge, attitudes, and behavior patterns of doctors is essential for developing successful strategies to improve lung cancer screening. This study aims to identify the attitudes, beliefs, referral practices, and knowledge of lung cancer screening among physicians in Saudi Arabia. METHODS: An online survey was conducted from July to December 2023 to investigate the attitudes, beliefs, referral practices, and knowledge of lung cancer screening, and adherence to lung cancer screening recommendations among physicians in Saudi Arabia. Internal medicine, family medicine, and pulmonology physicians of all levels (consultants, senior registrars, and residents) who are currently practicing medicine in Saudi Arabia formed the study population. This study employed a previously developed questionnaire. Binary logistic regression analysis was employed to identify factors that indicate a better degree of knowledge and a positive attitude toward lung cancer screening. RESULTS: This study involved a total of 96 physicians. The study participants demonstrated a significant degree of understanding regarding lung cancer screening, with an average knowledge score of 5.8 (SD: 1.7) out of 8, equivalent to 72.5% of the highest possible score. The accuracy rate for knowledge items varied from 44.8% to 91.7%. The study participants had a moderately favorable attitude toward lung cancer screening, as shown by a mean attitude score of 14.4 (SD: 3.7) out of a maximum possible score of 30, which corresponds to 48.0% of the highest achievable score. Around 36.5% of the survey participants reported engaging in the practice of discussing the results of lung cancer screening with patients. The primary obstacles frequently cited were challenges in patient scheduling, insufficient time to discuss lung cancer screening during clinic appointments, and patient refusal, constituting 59.4%, 53.1%, and 53.1% of the identified barriers, respectively. Physicians in Saudi Arabia, particularly those employed in private hospitals, demonstrated a higher level of knowledge of lung cancer screening compared to others (p < 0.05). In contrast, individuals with 11-15 years of experience were shown to have a 78.0% lower likelihood of being educated about lung cancer screening compared to their counterparts (p < 0.05). CONCLUSION: The study's results indicate that there is a need for the development of specialized educational initiatives aimed at Saudi Arabian physicians, particularly those with 11 to 15 years of experience who exhibit a limited understanding of lung cancer screening. Utilizing programs that provide continuing medical education would aid in their education. There is a need to facilitate communication between physicians and patients. It is critical to address the identified issues, such as streamlining the appointment scheduling process and ensuring patients have sufficient time during clinic visits. Furthermore, it is critical for the success of nationwide screening initiatives to foster collaboration between the public and private healthcare sectors.

RESUMEN

Background Saudi Vision 2030 is transforming the country's healthcare system, with efficacy, accessibility, and patient satisfaction with healthcare services serving as key indicators for assessing patient care quality. As blindness and impaired vision continue to be a rising health issue in most Eastern Mediterranean Region (EMR) nations, including Saudi Arabia, this study focused on measuring patient satisfaction with healthcare services in ophthalmology clinics. Objectives This study aimed to assess the level of patient satisfaction with healthcare services in ophthalmology clinics and its related factors in the Makkah region of Saudi Arabia in 2022-2023. Methods A cross-sectional study was conducted on a convenience sample of 553 Saudi and non-Saudi patients, aged 18 years and older, who attended private and government ophthalmology clinics in the Makkah region of Saudi Arabia during the period between November 2022 and February 2023. A self-administered questionnaire was distributed on several electronic platforms like WhatsApp, X (formerly known as Twitter), Telegram, and Snapchat to collect the data. Finally, all the data were entered and analyzed through the IBM SPSS software version 26. Results A total of 553 responses were obtained. The majority were aged between 18 and 35 years old (76.5%, n=423), with the female gender being dominant (79.7%, n=441). More than half of them (52.3%, n=289) preferred to receive ophthalmological healthcare services from governmental hospitals. The most commonly diagnosed eye disease was refractive error (43.2%, n=239). Patient satisfaction with healthcare services provided in ophthalmology clinics represented 75% (n=415). The odds of being satisfied with ophthalmology clinics are expected to decrease by at least 44% among individuals over the age of 35 (odds ratio (OR) =0.437; 95% CI=0.257-0.743; p=0.002). Moreover, those who had been married were predicted to decrease the chance of being satisfied by at least 50% compared to patients who had never been married (OR=0.538; 95% CI=0.352-0.823; p=0.004). Compared to students, patients who were currently employed were predicted to decrease the chance of being satisfied by at least 48% (OR = 0.481; 95% CI=0.270-0.856; p=0.013). Additionally, those with a higher monthly income had decreased odds of being satisfied by at least 58% (OR=0.583; 95% CI=0.381-0.893; p=0.013). In contrast, compared to patients with associated comorbidity, patients who have no comorbidity were predicted to have an increased chance of being satisfied by at least two-fold than those who had comorbidities (OR=2.023; 95% CI=1.199-3.413; p=0.008). Conclusions The study concludes that 75% of the patients attending ophthalmology clinics in the Makkah region of Saudi Arabia were satisfied with the healthcare services provided in these clinics. Most patients acknowledged the time of care, doctors' professionalism, continuity of care, comprehensive examination, and their education about their disease and management, in addition to doctors listening to them during their visits to ophthalmology clinics. Factors affecting patient satisfaction with medical services in ophthalmology clinics are patient age, occupation, marital status, monthly income, and associated comorbidities. Further studies are recommended to deeply understand patients' needs and obtain more suggestions to be fully satisfied with healthcare services in ophthalmology clinics and other different healthcare facilities.

RESUMEN

Background: The 2013 Kidney Disease: Improving Global Outcomes (KDIGO) guidelines recommends statin treatment for all adult kidney transplant recipients (KTRs), except those aged <30 years of age and without prior cardiovascular risk factors (CVRF), but does not specify on-treatment low-density lipoprotein cholesterol (LDL) target levels. The 2018 American Heart Association (AHA) guidelines addressed the management of hyperlipidemia in the general population based on an individualized approach of the CVRF with a specific on-treatment LDL target. Objective: To analyze dyslipidemia management according to the recommendations of the KDIGO and AHA guidelines. Methods: This retrospective study included all KTRs who underwent transplantation between January 2017 and May 2020 at King Abdulaziz Medical Center, Riyadh, Saudi Arabia. The rate of statins prescription in general, rate of statins prescription among KTRs per their CVRF, and rate of achieving the proposed LDL goals, as defined by the AHA, were analyzed. Results: A total of 287 KTRs were included. Of the 214 (74.6%) patients aged ≥30 years, 80% received a statin. Statins were prescribed in 93% and 96% of KTRs with diabetes or coronary artery disease, respectively. In patients aged ≥30 years, LDL targets, per AHA guidelines, were achieved in 62% with a target of 2.6 mmol/l, and in 19% with a target of 1.8 mmol/l. Statin therapy resulted in non-significant changes in the mean LDL values from baseline to 12 months after transplantation (P = 0.607), even when only patients prescribed statin after transplantation were included (P = 0.34). Conclusion: By applying the KDIGO guidelines, a high rate of statin prescriptions was achieved among KTRs with multiple CVRF and KTRs in general. However, a significant proportion of these KTRs did not achieve the LDL targets proposed by the AHA guidelines, suggesting that higher-intensity statins would be required to achieve these targets.

RESUMEN

A caregiver attends to the needs or concerns of someone limited by disease, injury, or disability to enhance the patient's quality of life, which can be assessed in three areas: social, physical, and psychological. This cross-sectional study assessed the extent of burden experienced by the caregivers of patients undergoing hemodialysis (HD) and peritoneal dialysis (PD) therapy in King Fahad Medical City in Riyadh, Saudi Arabia. The Zarit Burden Interview Arabic Abridged version (ZBI-A) was used to assess the level of burden experienced by caregivers. The data was collected and examined by professionals using the SPSS version 23. Based on the data of 50 participants, a mean ZBI-12 score of 12.22 ± 7.2 was reported. According to the ZBI scale, "No to mild burden," "Mild to moderate burden," and "High burden" were reported as 46% (n = 23), 38% (n = 19), and 16% (n = 8) of participants, respectively. The internal consistency of the ZBI-12 scale, assessed using Cronbach's alpha, was 0.664, indicating a satisfactory level of internal consistency. It was determined that caregivers of individuals undergoing PD and HD encounter different degrees of burden, with a significant proportion of caregivers experiencing a substantial burden.

RESUMEN

For almost two decades, clinicians have overlooked the diagnostic potential of CD34neg hematopoietic stem cells because of their limited homing capacity relative to CD34posHSCs when injected intravenously. This has contributed to the lack of appeal of using umbilical cord blood in HSC transplantation because its stem cell count is lower than bone marrow. The present study reveals that the homing and engraftment of CD34negHSCs can be improved by adding the Sialyl Lewis X molecule via α1,3-fucosylation. This unlocks the potential for using this more primitive stem cell to treat blood disorders because our findings show CD34negHSCs have the capacity to regenerate cells in the bone marrow of mice for several months. Furthermore, our RNA sequencing analysis revealed that CD34negHSCs have unique adhesion pathways, downregulated in CD34posHSCs, that facilitate interaction with the bone marrow niche. Our findings suggest that CD34neg cells will best thrive when the HSC resides in its microenvironment.

RESUMEN

Parkinson's Disease (PD) is a common disorder of the central nervous system. The Unified Parkinson's Disease Rating Scale or UPDRS is commonly used to track PD symptom progression because it displays the presence and severity of symptoms. To model the relationship between speech signal properties and UPDRS scores, this study develops a new method using Neuro-Fuzzy (ANFIS) and Optimized Learning Rate Learning Vector Quantization (OLVQ1). ANFIS is developed for different Membership Functions (MFs). The method is evaluated using Parkinson's telemonitoring dataset which includes a total of 5875 voice recordings from 42 individuals in the early stages of PD which comprises 28 men and 14 women. The dataset is comprised of 16 vocal features and Motor-UPDRS, and Total-UPDRS. The method is compared with other learning techniques. The results show that OLVQ1 combined with the ANFIS has provided the best results in predicting Motor-UPDRS and Total-UPDRS. The lowest Root Mean Square Error (RMSE) values (UPDRS (Total)=0.5732; UPDRS (Motor)=0.5645) and highest R-squared values (UPDRS (Total)=0.9876; UPDRS (Motor)=0.9911) are obtained by this method. The results are discussed and directions for future studies are presented.i.ANFIS and OLVQ1 are combined to predict UPDRS.ii.OLVQ1 is used for PD data segmentation.iii.ANFIS is developed for different MFs to predict Motor-UPDRS and Total-UPDRS.

RESUMEN

Background Hepatitis B is a global public health concern. Understanding the awareness, testing practices, and vaccination status of individuals is crucial for effective prevention and control strategies. This study aims to assess these aspects among participants in the Al-Baha region, Saudi Arabia. Methodology A cross-sectional study was conducted among 440 participants. Demographic data, awareness of hepatitis B, knowledge of transmission modes, symptoms, and complications were collected through a structured questionnaire. Participants' testing and screening practices, sources of information, and vaccination status were also assessed. Data were analyzed using descriptive statistics and associations were explored using chi-square tests. Results The majority of participants were females (51.8%) and aged 18-25 years (55.2%). While most participants had heard of hepatitis B (85.7%), only a small percentage correctly identified sexual contact as a mode of transmission (38.6%). Knowledge regarding symptoms and complications was moderate, with 52.3% correctly identifying symptoms and 69.8% recognizing liver damage and cirrhosis as complications. Although awareness of screening was high (84.8%), the actual practice was low (35.0%). Education was the least reported source of information, while the internet (46.7%) and health care provider (27.6%) were commonly mentioned. Approximately half of the participants reported receiving the hepatitis B vaccine (48.9%), but a significant proportion had not completed all vaccine doses (55.0%). Conclusion The study revealed moderate awareness of hepatitis B among the participants, but knowledge gaps existed regarding transmission modes and complete symptom recognition. Testing and screening practices were suboptimal, with low rates of screening despite high awareness. Vaccination uptake was moderate, but incomplete vaccine schedules were prevalent. Targeted educational campaigns are needed to address knowledge gaps, promote testing and completion of vaccination schedules, and enhance the role of healthcare providers in disseminating accurate information. Improving knowledge and practices related to hepatitis B can strengthen public health efforts, enhance prevention, and control strategies.

RESUMEN

ABSTRACT: Hepatitis C virus (HCV) infection has been a major global health concern, with a significant impact on public health. In recent years, there have been remarkable advancements in our understanding of HCV and the development of novel therapeutic agents. The Saudi Society for the Study of Liver Disease and Transplantation formed a working group to develop HCV practice guidelines in Saudi Arabia. The methodology used to create these guidelines involved a comprehensive review of available evidence, local data, and major international practice guidelines regarding HCV management. This updated guideline encompasses critical aspects of HCV care, including screening and diagnosis, assessing the severity of liver disease, and treatment strategies. The aim of this updated guideline is to assist healthcare providers in the management of HCV in Saudi Arabia. It summarizes the latest local studies on HCV epidemiology, significant changes in virus prevalence, and the importance of universal screening, particularly among high-risk populations. Moreover, it discusses the promising potential for HCV elimination as a public health threat by 2030, driven by effective treatment and comprehensive prevention strategies. This guideline also highlights evolving recommendations for advancing disease management, including the treatment of HCV patients with decompensated cirrhosis, treatment of those who have previously failed treatment with the newer medications, management in the context of liver transplantation and hepatocellular carcinoma, and treatment for special populations.

RESUMEN

BACKGROUND: There is a scarcity of studies examining the longitudinal relationship between dynapenic abdominal obesity (DAO; ie, impairment in muscle strength and high waist circumference) and future fall risk. Therefore, we aimed to investigate the prospective association between DAO at baseline and falls occurring during 2 years of follow-up in a nationally representative sample of middle-aged and older individuals from Ireland. METHODS: Data from 2 consecutive waves of the Irish Longitudinal Study on Ageing survey were analyzed. Dynapenia was defined as handgrip strength of <26 kg for men and <16 kg for women. Abdominal obesity was defined as a waist circumference of >88 cm for women and >102 cm for men. DAO was assessed at Wave 1 (2009-2011) and was defined as having both dynapenia and abdominal obesity. Falls occurring between Wave 1 and Wave 2 (2012-2013) were self-reported. Multivariable logistic regression analysis was conducted. RESULTS: Data on 5 275 individuals aged ≥50 years were analyzed (mean [standard deviation {SD}] age 63.2 [8.9] years; 48.8% males). After adjustment for potential confounders, compared to no dynapenia and no abdominal obesity at baseline, DAO was significantly associated with 1.47 (95% confidence interval [CI]: 1.14-1.89) times higher odds for falls at 2-year follow-up. Dynapenia alone (odds ratio [OR] = 1.08; 95% CI: 0.84-1.40) and abdominal obesity alone (OR = 1.09; 95% CI: 0.91-1.29) were not significantly associated with falls at follow-up. CONCLUSIONS: DAO increased the risk for falls among middle-aged and older adults in Ireland. Interventions to prevent or reverse DAO may be beneficial for fall reduction.
