RESUMO

OBJECTIVES: To assess clinicians' adherence to fingolimod's effective use according to the prescribed recommendations to reduce safety risk, identify the consequences, and highlight areas for improvement to policy makers for the benefit of both patient and care-giver. METHODS: A retrospective observational study conducted at a tertiary hospital targeting multiple sclerosis patients on fingolimod from January 2017 to December 2021. The physicians' adherence to the manufacturer's instructions was assessed and categorized into good, moderate, and poor based on adherence to fingolimod instructions and monitoring measures. Four monitoring measures were assessed: bradycardia observation, ophthalmic examination, liver enzymes, and infections. In addition, the impact of adherence on patient safety was also assessed. RESULTS: A total of 140 patients were included. Seventy-twopatients (51.4%) had physician with poor adherence (followed only one instruction or none). Sixty-five patients (46.4%) had 2-3 manufacture recommendations where physician's adherence was moderate. Three patients (2.10%) had all manufacturer's recommendations. In terms of fingolimod complications, 18 patients found to have bradycardia after the first does, macular oedema and infections was reported in 4 patients, and the elevation in hepatic enzymes was reported in 6 patients. Poor physician's adherence has resulted in treatment incompleteness and highest fingolimod discontinuation or switching to other treatment options. CONCLUSION: Adherence to fingolimod instructions was poor among physicians which resulted in highest drug switching or discontinuing rate.

RESUMO

OBJECTIVES: To construct a new prognostic prediction model for detecting Prostate Cancer (PCa) patients using Machine Learning (ML) techniques and to compare those models across systematic and target biopsy detection techniques. METHODS: The records of the two main hospitals in Riyadh, Saudi Arabia, were analyzed for data on diagnosed PCa from 2019 - 2023. Four ML algorithms were utilized for the prediction and classification of PCa. RESULTS: 528 patients with prostate-specific antigen (PSA) greater than 3.5 ng/mL who had undergone transrectal ultrasound-guided prostate biopsy (TRUS) were evaluated. The total number of confirmed PCa cases was 234. Age, prostate volume, PSA, Body Mass Index (BMI), multiparametric Magnetic Resonance Imaging (mpMRI) score, number of regions of interest detected in MRI, and the diameter of the largest size lesion were significantly associated with PCa. Random Forest (RF) and XG Boost (XGB) (ML algorithms) accurately predicted PCa. Yet, their performance for classification and prediction of PCa was higher and more accurate for cases detected by targeted and combined biopsy (systematic and targeted together) compared to systematic biopsy alone. F1, the Area Under the Curve (AUC), and the accuracy of XGB and RF models for targeted biopsy and combined biopsy ranged from 0.94 - 0.97 compared to the AUC of systematic biopsy for RF and XGB algorithms, respectively. CONCLUSIONS: The Random Forest (RF) model generated and presented an excellent prediction capability for the risk of PCa detected by targeted and combined biopsy compared to systematic biopsy alone. ML models can prevent missed PCa diagnoses by serving as a screening tool.

RESUMO

BACKGROUND: Data on the impact of liver transplantation (LT) in cystic fibrosis (CF) on lung function and exacerbations are limited. The objective of this study was to summarize the literature on lung function, nutritional status, survival, and complications following LT in people with CF. METHODS: Three databases were searched until September 2023, to identify the impact of LT in CF. Lung transplant prior to LT and simultaneous liver-lung transplant were excluded. Pooled hazard ratios were calculated using random-effects models. RESULTS: Thirty studies were included in this review, with 3 and 9 studies included in meta-analyses for nutritional status and lung function, respectively. Eighty-three percent of the studies used data that was more than a decade old. There was a significant increase in percent-predicted forced expiratory volume with mean change of 7.16 % (2.13, 12.19; p = 0.005) one year post-LT. Pulmonary exacerbations decreased in the short-term, however there was no significant change in body mass index (BMI). One-year survival post-LT ranged between 75 and 100 %, while five-year survival was lower at 64-89 %. CONCLUSION: Existing data suggest that LT improves lung function in the short term and does not increase the likelihood of pulmonary exacerbations, despite ongoing immunosuppression in the setting of chronic lung infection.

RESUMO

Background: Incidence and outcomes of acute kidney injury (AKI) among neonates who underwent open-heart surgery are not well highlighted in the literature. We aim to assess the incidence, risk factors, and outcome of AKI among neonates undergoing open-heart surgery. Methods: This is a retrospective cohort study between 2016 and 2021 for all neonates requiring open heart surgery. The cases were divided into 2 groups: the AKI (index) group and the non-AKI (control) group. The two groups were statistically compared for risk factors, needs for dialysis, and outcomes. Results: 100 patients fulfilled the inclusion criteria. Among them, 74 (74%) developed AKI, including 41 (55%), 15 (21%), and 18 (24%) patients in KDIGO stages 1, 2, and 3, respectively. Multivariate analysis comparing both groups demonstrated that low pre-operative creatinine (p = 0.01), prolonged bypass time (p = 0.0004) and high vasoactive inotropic score (VIS), (p = 0.0008) were risk factors for developing AKI post-operatively. Furthermore, in the AKI group, 17 (23%) neonates required renal replacement therapy in the form of peritoneal dialysis. The length of stay was higher in the AKI index group (p = 0.015). Patients who had AKI recovered their kidney function at discharge. There was no difference in mortality between both groups. Conclusion: The AKI occurred in 74% of neonates undergoing open-heart surgery, with 23% of them needing peritoneal dialysis. Low pre-operative creatinine, high VIS score, and prolonged bypass time are potential risk factors for AKI development after neonatal open-heart surgery. AKI may lead to prolonged hospitalization, though most affected patients recovered their normal kidney function at discharge.

RESUMO

BACKGROUND: Erectile dysfunction (ED) is defined as the inability to achieve and maintain an erection powerful enough to permit pleasurable sexual activity. There are four categories for ED grades. The illness may be influenced by vascular, neurological, psychological, and hormonal factors. Anxiety about performance and relationship issues are common psychological triggers. AIM: This study aimed to determine the prevalence, risk factors, and awareness of ED and its management in the population of Saudi Arabia. METHOD: This community-based, cross-sectional study was conducted among adult Saudi males in all five regions of Saudi Arabia (Central, Eastern, Western, Southern, and Northern). A self-administered questionnaire was distributed among participants using an online survey. The questionnaire includes sociodemographic data (i.e., age, region, marital status, education), medical history, and erectile function (International Index of Erectile Function (IIEF-5)) as a diagnostic tool for ED. RESULTS: In total, 924 men took part. About 512 (55.4%) were aged between 18 and 25 years old, and nearly two-thirds (595, 64.4%) were single. The Internet was the most common source of ED information 495 (53.6%). Based on respondents' knowledge, the most common risk factor of ED was depression (561, 60.8%), while the most common treatment option was lifestyle modification (654, 70.8%). The prevalence of ED among adult Saudi men was 198 (21.4%). Independent risk factors for ED include having been married, being an employee, and previous operation of the perineum. CONCLUSION: ED was common among the Saudi male population. ED was more prevalent among older men with associated chronic diseases and had elevated body mass index (BMI). Having been married, being an employee, and having a previous perineum operation were identified as the significant independent risk factors for ED. Longitudinal studies are needed to determine the cause and effect of the recognized risk factors for ED among men.

RESUMO

Background/aims Most countries have gone through lockdowns to varying degrees during the COVID-19 pandemic to reduce the spread of the disease. The successive pandemic waves have impacted the health system, imposing restrictions set by the government. This changed people's daily life routines and they felt more socially isolated, which in turn had an impact on their mental health. Some factors were linked to the severity and outcome of COVID-19 on patients. One of these factors was smoking. This study was carried out to investigate the prevalence and impact of lockdown on smoking habits, as well as the changes in attitudes, behavior, and the rate of consumption before and after the government restrictions in the general population of Saudi Arabia. Materials and methods The present cross-sectional study was conducted on a sample of 921 participants from the general population of Saudi Arabia. Data were collected via an online questionnaire. A structured self-response questionnaire was given to the participants after institutional research ethical approval was obtained for the study. Results A total of 921 participants from the smoker population of Saudi Arabia were included in the study. The majority of participants were male (72.9%), and more than half were aged between 18 and 34 years (53.7%). Single individuals had a higher prevalence of increased smoking and a lower rate of quitting compared to married individuals. Participants with higher education levels were more likely to continue smoking at the same rate. While 40.5% of participants reported no change in their smoking rate during the pandemic, 15.4% reported a decrease, 39.0% reported an increase, and 5.1% reported quitting smoking. Participants who reported feeling more stressed during the pandemic had a higher prevalence of increased smoking. The majority of participants believed that smoking increased the risk of COVID-19 infection. Conclusion The study highlights the need for targeted smoking cessation interventions and support services during the pandemic, considering demographic factors, living arrangements, and psychological impact. Efforts should be made to raise awareness about the negative health consequences of smoking during the pandemic and provide resources for stress management and alternative coping strategies. These findings have important implications for public health interventions and policies in Saudi Arabia.

RESUMO

Background/aims Medial tibial stress syndrome (MTSS), also known as "shin splint", is most often described as exertional leg pain along the shinbone (tibia), which occurs due to the inflammation of the muscles, tendons, and bone tissue in this area. This study aims to assess the prevalence, risk factors, and their association with the development of MTSS, as well as the effective treatments that reduce pain and improve functions among the Saudi general population. Materials and method The present cross-sectional study was conducted on the general population of Saudi Arabia through an electronic survey over a period of three months. The study sample of 443 patients was deemed and considered. The study included participants from the general population in Saudi Arabia above the age of 18. A structured self-response questionnaire was given to the participants after institutional research ethical approval was obtained for the study. Results Among the 443 participants, the majority were male (n = 228, 51.5%), aged 18-29 (n = 227, 51.2%), and residing in the central region of Saudi Arabia (n = 398, 89.8%). Most participants reported engaging in sporting activities (n = 211, 47.6%), with high-intensity training being the most common (n = 93, 44.1%). Only a small proportion (n = 8, 1.8%) reported a previous diagnosis of MTSS. Analysis revealed associations between MTSS prevalence and certain demographic factors, including walking surface preferences and engagement in specific sports. Treatment strategies for MTSS included rest, ice application, physiotherapy, and pain-relieving medication, with varying degrees of satisfaction and recurrence rates among participants. Conclusion The study provides valuable insights into the prevalence, risk factors, management, and preventive measures related to MTSS among the Saudi general population. While certain demographic factors and exercise practices were associated with MTSS prevalence, effective treatment options such as rest, physiotherapy, and appropriate footwear were reported. Moreover, adherence to preventive measures such as stretching, proper footwear selection, and gradual training progression may help mitigate the risk of MTSS development.

RESUMO

Background Cerebral palsy (CP) is a major cause of childhood motor impairment worldwide. The prevalence of CP related to preterm births has increased consistently. Perinatal hypoxic-ischemic encephalopathy, intra- or periventricular haemorrhage, cerebral dysgenesis and intracranial infections are among the factors contributing to CP onset. Several studies have explored epilepsy-related morbidity among children with CP, finding notable correlations between the two conditions. Worldwide, there are multiple studies highlighting the high prevalence of epilepsy among children with CP and its association with specific CP subtypes and neurologic insults. However, research on the risk factors for epilepsy in CP children is limited, particularly in the Middle East and Saudi Arabia. Aim This study aims to address this gap by analysing potential prenatal, antenatal, and postnatal risk factors associated with epilepsy development in children with CP. Methods A retrospective cohort analysis of 152 children aged 1-14 years diagnosed with CP at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, was conducted. Results The study showed a significant prevalence of epilepsy (68.4%), with generalised seizures being the most common type. Quadriplegia was notably common among CP children with epilepsy, indicating a potential correlation between motor impairment severity and epilepsy risk. Furthermore, CP children with epilepsy exhibited a higher prevalence of co-morbidities, emphasising the multifaceted nature of this condition. Perinatal and neonatal factors, such as hypoxic events, mechanical ventilation, perinatal asphyxia, neonatal convulsions, and microcephaly, were identified as significant risk factors for epilepsy in children with CP. While speech and hearing disorders were present in CP children with and without epilepsy, a slightly higher prevalence of impaired speech was observed in those with epilepsy. However, the difference between the two groups was not significant. Conclusion This study provides valuable insights into the epidemiology, clinical characteristics and potential risk factors associated with epilepsy among children diagnosed with CP in Saudi Arabia. The findings underscore the complexity of managing epilepsy in this population and highlight the need for further research to elucidate the underlying mechanisms and support the development of targeted interventions to improve patient outcomes.

RESUMO

OBJECTIVES: To determine the effectiveness and safety of Hemopatch® as a primary dural sealant in preventing CSF leakage following cranial surgery. Cerebrospinal fluid (CSF) leaks occur in cranial operations and are associated with significant patient burden and expense. The use of Hemopatch® as a dural sealant in cranial neurosurgical procedures is described and analyzed in this study. METHODS: Data were retrospectively collected from all patients who underwent a craniotomy for various neurosurgical indications where Hemopatch® was used as the primary dural sealant between June 2017 and June 2022. Infection and CSF leak were the main indicators evaluated after surgery. RESULTS: A total of 119 consecutive patients met our inclusion criteria. The median was age 41.5 years, and 52.5% were female. The mean follow-up period was 2.3 years (7 months to 6 years). There were 110 (92.44%) supratentorial and 9 (7.56%) infratentorial craniotomies. Postoperative CSF leak was reported in 2 patients (1.68%), one in each cohort. Postoperative infection occurred in one patient (0.84%). CONCLUSION: The results suggest that using Hemopatch® as a dural sealant in cranial surgery is effective and safe. After supra-/infratentorial craniotomies, the rate of postoperative adverse events in our sample was within the range of known surgical revision rates. Future randomized clinical studies are required to confirm our encouraging findings.

RESUMO

BACKGROUND: Pediatric patients with moderate-to-severe atopic dermatitis (AD) often experience a high disease burden and have a high risk of persistent disease. Standard-of-care immunosuppressive systemic treatments have been used off-label for AD in pediatric patients despite concerns for suboptimal safety with continuous use and risk of relapse upon discontinuation. The biologic agent dupilumab is the first systemic treatment approved for moderate-to-severe AD in children as young as 6 months. Long-term safety and efficacy data in this patient population are needed to inform continuous AD management. OBJECTIVES: The purpose of this work was to determine the long-term safety and efficacy of dupilumab treatment up to 1 year in an open-label extension (OLE) study [LIBERTY AD PED-OLE (NCT02612454)] in children aged 6 months to 5 years with moderate-to-severe AD who previously participated in the 16-week, double-blind, phase 3 LIBERTY AD PRESCHOOL trial (NCT03346434 part B; parent study) and were subsequently enrolled in PED-OLE. METHODS: In PED-OLE, patients received dupilumab every 4 weeks according to a weight-tiered regimen (body weight ≥ 5 kg to < 15 kg: 200 mg; ≥ 15 kg to < 30 kg: 300 mg). RESULTS: Data for 142 patients were analyzed, 60 of whom had completed the 52-week visit at time of database lock. Mean age at baseline was 4.1 y [SD, 1.13; range, 1.0-5.9 years]. A majority (78.2%) of patients reported ≥ 1 treatment-emergent adverse event (TEAE), most of which were mild or moderate and transient. The most frequently reported TEAEs were nasopharyngitis (19.7%), cough (15.5%), and pyrexia (14.1%). One TEAE led to treatment discontinuation (severe urticaria, which resolved in 1 day). By week 52, 36.2% of patients had achieved an Investigator's Global Assessment score of 0/1 (clear/almost clear skin), and 96.6%, 79.3%, and 58.6% had at least 50%, 75%, or 90% improvement, respectively, in Eczema Area and Severity Index scores. CONCLUSIONS: Consistent with results seen in adults, adolescents, and older children (aged 6-11 years), treatment with dupilumab for up to 1 year in children aged 6 months to 5 years with inadequately controlled moderate-to-severe AD demonstrated an acceptable long-term safety profile and sustained efficacy. These results support the long-term continuous use of dupilumab in this patient population. TRIAL REGISTRATION: ClinicalTrials.gov Identifiers: NCT02612454 and NCT03346434 (part B).


Atopic dermatitis (AD) is a chronic inflammatory skin disease that often results in a high disease burden in young children and their families. Patients often need long-term treatment to control their disease symptoms, including itch and rash. Dupilumab treatment for 16 weeks has shown benefits in children aged 6 months to 5 years with moderate-to-severe AD, with an acceptable safety profile. As AD is likely to continue from childhood into adolescence and adulthood, there is a need for data supporting long-term use of dupilumab in young children. In this study, children who completed the 16-week study continued dupilumab treatment for up to 1 year, receiving 200 mg or 300 mg of dupilumab (depending on the child's bodyweight) every 4 weeks. Through the year of treatment, 78.2% of patients reported at least one side effect, most of which were mild or moderate. Only one patient interrupted treatment because of severe skin rash (hives), which was resolved in 1 day. At the end of the year, 36.2% of patients had clear or almost clear skin, and almost all (96.6%) achieved at least 50% improvement in their extent and severity of disease. Additionally, 79.3%, and 58.6% had at least 75% or 90% improvement in their extent and severity of disease. In summary, consistent with results seen in adults, adolescents, and older children, this study showed that 1-year dupilumab treatment provides continued benefits with an acceptable safety profile. These results support long-term continuous use of dupilumab in children aged 6 months to 5 years with moderate-to-severe AD. What is the long-term safety and efficacy profile in young children with moderate-to-severeatopic dermatitis treated with dupilumab?

RESUMO

This case report details a complex case of parotid gland sialolithiasis with stones adherent to the facial nerve, a scenario that presents a significant surgical challenge. Traditional sialendoscopy failed to address the condition in a 23-year-old female patient, leading to the adoption of a combined endoscopic transcutaneous approach. This method successfully resolved the condition without intraoperative complications, maintaining intact facial nerve function postoperatively. The case emphasizes the importance of individualized surgical strategy and expert technique in advanced parotid surgery, advocating this approach for similarly complex sialolithiasis cases.

RESUMO

Large randomized trials in sepsis have generally failed to find effective novel treatments. This is increasingly attributed to patient heterogeneity, including heterogeneous cardiovascular changes in septic shock. We discuss the potential for machine learning systems to personalize cardiovascular resuscitation in sepsis. While the literature is replete with proofs of concept, the technological readiness of current systems is low, with a paucity of clinical trials and proven patient benefit. Systems may be vulnerable to confounding and poor generalization to new patient populations or contemporary patterns of care. Typical electronic health records do not capture rich enough data, at sufficient temporal resolution, to produce systems that make actionable treatment suggestions. To resolve these issues, we recommend a simultaneous focus on technical challenges and removing barriers to translation. This will involve improving data quality, adopting causally grounded models, prioritizing safety assessment and integration into healthcare workflows, conducting randomized clinical trials and aligning with regulatory requirements.

RESUMO

Background: The hunt for naturally occurring antiviral compounds to combat viral infection was expedited when COVID-19 and Ebola spread rapidly. Phytochemicals from Nyctanthes arbor-tristis Linn were evaluated as significant inhibitors of these viruses. Methods: Computational tools and techniques were used to assess the binding pattern of phytochemicals from Nyctanthes arbor-tristis Linn to Ebola virus VP35, SARS-CoV-2 protease, Nipah virus glycoprotein, and chikungunya virus. Results: Virtual screening and AutoDock analysis revealed that arborside-C, beta amyrin, and beta-sitosterol exhibited a substantial binding affinity for specific viral targets. The arborside-C and beta-sitosterol molecules were shown to have binding energies of -8.65 and -9.11 kcal/mol, respectively, when interacting with the major protease. Simultaneously, the medication remdesivir exhibited a control value of -6.18 kcal/mol. The measured affinity of phytochemicals for the other investigated targets was -7.52 for beta-amyrin against Ebola and -6.33 kcal/mol for nicotiflorin against Nipah virus targets. Additional molecular dynamics simulation (MDS) conducted on the molecules with significant antiviral potential, specifically the beta-amyrin-VP35 complex showing a stable RMSD pattern, yielded encouraging outcomes. Conclusions: Arborside-C, beta-sitosterol, beta-amyrin, and nicotiflorin could be established as excellent natural antiviral compounds derived from Nyctanthes arbor-tristis Linn. The virus-suppressing phytochemicals in this plant make it a compelling target for both in vitro and in vivo research in the future.

RESUMO

Colorectal cancer (CRC) is the third most common cancer affecting people. The discovery of new, non-invasive, specific, and sensitive molecular biomarkers for CRC may assist in the diagnosis and support therapeutic decision making. Exosomal miRNAs have been demonstrated in carcinogenesis and CRC development, which makes these miRNAs strong biomarkers for CRC. Deep sequencing allows a robust high-throughput informatics investigation of the types and abundance of exosomal miRNAs. Thus, exosomal miRNAs can be efficiently examined as diagnostic biomarkers for disease screening. In the present study, a number of 660 mature miRNAs were detected in patients diagnosed with CRC at different stages. Of which, 29 miRNAs were differentially expressed in CRC patients compared with healthy controls. Twenty-nine miRNAs with high abundance levels were further selected for subsequent analysis. These miRNAs were either highly up-regulated (e.g., let-7a-5p, let-7c-5p, let-7f-5p, let-7d-3p, miR-423-5p, miR-3184-5p, and miR-584) or down-regulated (e.g., miR-30a-5p, miR-99-5p, miR-150-5p, miR-26-5p and miR-204-5p). These miRNAs influence critical genes in CRC, leading to either tumor growth or suppression. Most of the reported diagnostic exosomal miRNAs were shown to be circulating in blood serum. The latter is a novel miRNA that was found in exosomal profile of blood serum. Some of the predicted target genes of highly expressed miRNAs participate in several cancer pathways, including CRC pathway. These target genes include tumor suppressor genes, oncogenes and DNA repair genes. Main focus was given to multiple critical signaling cross-talking pathways including transforming growth factor ß (TGFß) signaling pathways that are directly linked to CRC. In conclusion, we recommend further analysis in order to experimentally confirm exact relationships between selected differentially expressed miRNAs and their predicted target genes and downstream functional consequences.

RESUMO

Introduction The use of robotic-assisted surgeries (RAS) has been growing in surgical specialties. It allows surgeons to perform higher-quality operations with fewer complications, mortality, and morbidity. However, there are a lot of misconceptions about RAS among patients. Therefore, our study aimed to assess the knowledge, attitude, awareness, and future expectations of RAS in patients attending surgical clinics. Methods  A cross-sectional study was conducted in King Abdulaziz Medical City (KAMC) surgical clinics in Riyadh, Saudi Arabia. All participants <18 years of age were excluded. The questionnaire was distributed to 304 patients attending surgical clinics with a confidence level of 95% and a margin of error of 5%. Cluster sampling was used since the respondents were from multiple surgical specialties. Finally, multivariate analysis was performed to assess participants' preference for robotic surgery. Results Most participants (58.6%, n=178) were between 21 and 40 years old, and males were 52% of the participants. Many respondents thought a robot did not do the surgery. 70.7% of respondents had not heard of robotic surgery, with the media being the most common source of information. Internal damage was the prevalent concern (51.0%, n= 155) in malfunctions of robotic surgery. A significant relationship was found between participants from 21 to 40 years of age and a stronger preference for robotic surgery (p=.027). Respondents who preferred robotic surgery were discovered to have a significant relationship with participants who thought robotic surgery was safer and had better results (p<.001). 13.9% of participants who did not prefer robotic surgery also took cost into account significantly (χ2=28.93, p<.001, Cramer's V=.22). 67.2% (n=43) of respondents who preferred robotic surgery believed it might eventually replace present practices. Conclusion Our study concluded that the majority did not favor or were unsure whether to undergo robotic surgeries or not. However, most participants had some misconceptions and a lack of awareness about robotic surgeries. Raising awareness among patients can improve the mutual decision-making between them and their treating physician.

RESUMO

Background Hajj, the annual Islamic pilgrimage, brings together over two million pilgrims in the city of Makkah to participate in a series of rituals. Given the physically demanding nature of the Hajj, pilgrims are susceptible to musculoskeletal (MSK) injuries and exhaustion. MSK pain and injuries are frequent occurrences among pilgrims, necessitating an assessment of the scope of this issue. Therefore, the primary objective of this study was to determine the prevalence of MSK injuries among pilgrims during the 2023 Hajj season. Methods This is a cross-sectional questionnaire-based study that was conducted in the city of Makkah, Saudi Arabia, during the 2023 Hajj season. Results A total of 463 pilgrims were included in the analysis. The most frequently reported types of injuries were muscular injuries (169, 45.4%), primarily characterized by pain (99, 58.6%), muscle spasms (55, 32.5%), and muscle tears (eight, 4.7%). The second most commonly reported MSK injury was bony injuries (97, 26.1%), which included fractures, followed by 79 cases (21.2%) of joint injuries, predominantly featuring pain (69, 87.3%) and joint prolapse (10, 12.7%). Notably, 27 pilgrims (7.3%) suffered from ligament injuries, including tears. Regarding the mechanisms or causes of these MSK injuries, the most frequently reported factors were fatigue (206, 55.4%), falls (76, 20.4%), crowding (34, 9.1%), accidents (30, 8.1%), and the use of wheelchairs (14, 3.8%). Additionally, it is noteworthy that muscular injuries were more prevalent among all age groups, particularly among young-aged pilgrims, while joint injuries were more common among elderly pilgrims. Conclusion MSK injuries are prevalent among pilgrims, with muscular injuries being the most frequently encountered. This underscores a noteworthy public health concern that necessitates attention from the Ministry of Health of Saudi Arabia.

RESUMO

Introduction: IPE fosters a dynamic learning environment that may promote students' knowledge, abilities, and collaborative approach towards addressing challenging clinical circumstances. While much has been reported in the literature regarding these diverse IPE learning environments, limited information exists regarding clinical preceptors' attitude and perceptions of IPE, especially in Saudi Arabia. Given the impact clinical preceptors have on the formation of healthcare students exploring their perceptions, which may impact their actions is imperative. Methodology: The study focused on understanding the attitudes and perceptions of clinical preceptors towards IPE in a healthcare setting in Saudi Arabia. The study was conducted in Saudi Arabia. Data was collected via Email letter of solicitation (LOS) which included a link to the Readiness for Interprofessional Learning Scale (RIPLS) survey. The LOS was sent to all the health care programs in Saudi Arabia. Results: The study surveyed 182 clinical preceptors. The findings revealed consistent favorable opinions towards "Teamwork and Collaboration". The majority of preceptors concurred that learning alongside other students would increase students' efficiency on healthcare teams and deepen their comprehension of clinical issues. The "Roles and Responsibilities" category, however, obtained lower ranks in general from the preceptors. Not surprising, differences in rankings were greatest between preceptors who had and did not have IPE exposure, there were significant variations in views toward "Teamwork and Collaboration", "Negative Professional Identity", and "Roles and Responsibilities". Preceptors exposed to IPE showed lower median ratings for "Negative Professional Identity" and "Roles and Responsibilities" and better median scores for "Teamwork and Collaboration". Conclusion: The attitudes and perceptions of preceptors who had experienced IPE were more favorable toward IPE and thus may foster it more effectively in the students they work with. Therefore, ensuring that all preceptors are aware of and have experience with IPE is important as we seek to promote person-centered care.

RESUMO

Introduction  Dental surfaces have dense bacterial deposits, and poor oral hygiene can exacerbate bacterial infections, causing acute tonsillitis. The study aims to quantify acute tonsillitis prevalence and assess its association with oral hygiene practices. Methods  A descriptive cross-sectional study aimed to assess the prevalence of acute tonsillitis and its association with oral hygiene was conducted among adults aged 20 and above in Taif City, Saudi Arabia. Illiterates and those unwilling to participate were excluded. We employed an Arabic online self-administered questionnaire that was disseminated conveniently via Google Forms to social media assessing oral hygiene such as last dental visit, age at starting dental care, number of toothbrushes per day, frequency of toothbrush change, and duration of brushing teeth, and acute tonsillitis characteristics of the participants. Results About 393 participated in the study. Of them, 54% were aged 20-30, 53% were males, and 70% had a university education. The prevalence of acute tonsillitis was 64%. Approximately 28% reported dental clinic visits within three months, and 21% initiated oral hygiene practices at age 20. Among participants, 43% brushed twice daily, with 33% spending one minute and 43% two minutes. About 31% replaced toothbrushes every three months, while 23% acknowledged having bad breath. Experiencing bad breath, changing toothbrushes every three months, and having dental visits within less than three months were associated with having acute tonsillitis (p<0.05). However, regression analysis revealed that experiencing bad breath (OR: 2.11, 95% CI: 1.23, 3.70) was associated with a higher risk of acute tonsillitis, while less frequent toothbrush changes correlated with a lower risk (OR: 0.54, 95% CI: 0.30, 0.94). Conclusion  This study revealed a substantial prevalence of acute tonsillitis among adults in Taif City. Oral care practices need improvement. There are significant associations between oral hygiene practices, bad breath, and the occurrence of acute tonsillitis. Addressing oral hygiene practices could be a key focus for preventative measures.

RESUMO

BACKGROUND:  A clinical condition known as chronic otitis media (COM) is characterized by tympanic membrane perforation, varying degrees of hearing loss, and otorrhea that lasts for two to six weeks. COM alone or with cholesteatoma may result in ossicular chain discontinuity and ossicular erosion. The hearing restoration procedure includes repairing the eardrum and building the ossicular chain in ears with damaged ossicles. Multiple studies suggest the predictive value of preoperative air-bone gap (ABG) to detect the ossicular chain status can help with proper preoperative planning for surgery. OBJECTIVE: To determine the degree of hearing improvement and reduction in ABG after tympanoplasty and to investigate the correlation between preoperative ABG and the status of the ossicular chain during surgery. Study design, setting, and date: This retrospective hospital file-based study was conducted at Aseer Central Hospital, Southern Region, Saudi Arabia, between November 2022 and April 2023. Hospital records of patients who underwent tympanoplasty during 2018-2023 were reviewed. Eighty-five patients were diagnosed with chronic suppurative otitis media (CSOM) between 2018 and 2023. A data collection sheet was employed to record extracted data, including the patient's age, sex, hearing assessment, type of surgical intervention, and outcome. We calculated the average of ABG decibels (dB) by summing the ABG values at 500 Hz, 1000 Hz, and 2000 Hz frequencies and dividing by three. RESULTS: In the present study, data from 85 patients who underwent tympanoplasty were analyzed. Approximately one-third of the patients were in the age group of 31 to 40 years (25, 29.4%), and 50 (58.8%) of them were females. Chronic medical conditions were observed in 30 (35.3%) patients, with diabetes being reported in 19 (63.3%) of those cases. CSOM was found to be present in the left ear of 47 (56.0%) patients. Among the patients, 25 (29.4%) had subtotal perforations, 12 (14.1%) had marginal perforations, and two (2.4%) had total tympanic membrane perforations. The majority of patients (67, 78.8%) exhibited conductive hearing loss, while the remaining 18 (21.2%) had mixed hearing loss. Of the patients, 13 (15.3%) and 20 (23.5%) had fixed and disrupted ossicular chains, respectively. In terms of ossicular disruption, incudostapedial joint (ISJ) fixing (21.2%), fixed stapes (18.2%), and ISJ dislocation (18.2%) were the most prevalent kinds. Prior to operations, the mean ± SD of ABG was 22.6 ± 7.5. ABG values were 19.0 ± 9.3 on average after surgery. The statistical difference between pre- and postoperative ABG was statistically significant (paired t-test, p = 0.007), with a mean difference of -3.7. There were no significant differences between the different statuses of ossicular chains and the type of tympanic membrane perforation. CONCLUSION: This study suggests that the degree of preoperative ABG (dB) is a valuable predictor of intraoperative ossicular chain status and can aid in preoperative planning for ossicular chain reconstruction. Furthermore, the study found that the type of tympanic membrane perforation preoperatively is not a reliable indicator of the ossicular chain status. Finally, tympanoplasty is considered a beneficial surgical procedure with a significant improvement in hearing status postoperatively.
