RESUMO

This is the first study to develop research priorities in tobacco use and substance abuse in Saudi Arabia. Health personnel and community volunteers participated in a national internet survey using the Delphi method. In Round 1, 75 experts identified 33 research priorities. In Round 2, 47 experts divided those research priorities into five primary research categories. The panelists then scored both the categories and priorities. Preventive services received the highest priority in research categories. Smoking relapse and its determinants were ranked the top research priorities. Future research should focus on cigarette smoking relapse and factors associated with long-term smoking cessation.

RESUMO

INTRODUCTION: Continuous positive airway pressure (CPAP) may induce nasal inflammation because of mucosal compression or dryness. This study examined the impact of humidified versus nonhumidified CPAP on nasal inflammation and upper airway symptoms. METHODS: Seventeen healthy male subjects with no previous or current history of nasal symptoms were recruited. All subjects underwent 3 hours of nonhumidified CPAP at 12.5 cmH2O via nasal mask. Among the 17 studied subjects, seven returned to receive a humidified CPAP at 12.5 cmH2O via nasal mask. The nasal wash leukocyte count was assessed at baseline and after each CPAP setting. The white blood cell (WBC) count and levels of WBCs that are mononuclear cells (including lymphocytes and monocytes) were monitored. A six-point nasal score was also assessed before and after the CPAP intervention. RESULTS: The nasal wash WBC count (103/µL) and mononuclear cell level (103/µL) at baseline, on 12.5 cmH2O humidified CPAP, and on 12.5 cmH2O nonhumidified CPAP were significantly different (p = 0.016; p = 0.003). Changes in nasopharyngeal symptoms occurred in 12 of 17 subjects (70.5%) in the nonhumidified group. Participants experienced at least one nasal symptom after application of nonhumidified CPAP at 12.5 cmH2O. CONCLUSION: The present investigation suggests that humidified CPAP was not associated with early nasal inflammation and there were fewer nasopharyngeal symptoms. Further study is required to confirm the results and evaluate the impact of adding heat to the humidified CPAP system.

RESUMO

OBJECTIVE: To determine the quality of life (QoL) among multiple sclerosis (MS) patients in Kingdom of Saudi Arabia. METHODS: A cross-sectional study was carried out to assess the QoL of MS patients during the period from November 2016 to May 2017. Patients were recruited from tertiary hospitals in 5 regions in the kingdom. Clinical and demographic data were collected and information on patients` health status using the self-report SF-36 questionnaire to assess QoL. The Patient Determined Disease Steps (PDDS) was used to measure disability. Data were analyzed using descriptive statistics, the Mann-Whitney test, the Kruskal Wallis test and Spearman`s coefficient correlation. RESULTS: From the 598 MS patients studied, 384 (64.2%) were female. The mean score for males was higher than females in all SF-36 QoL subscales. The mean age was 32.4 years (SD=8.4). The mean duration of illness was 6.5 years. Patients had the lowest scores in role motioning/emotional scale (mean=42.6, SD=43.3). The PDDS was negatively correlated with all SF-36 QoL subscales. Self Report-36 QoL for MS patients differed significantly through demographic characteristics at a level of significance of 0.05. CONCLUSION: Multiple Sclerosis patients have a low QoL score and need more comprehensive management by their treating physicians. Further development of the registration will provide access to the entire population of MS patients and help comprehensively analyze the factors that affect the quality of their lives.

RESUMO

Multinodular goiter (MNG) is a chronic benign nodular enlargement of the thyroid gland. It presents as an anterior painless neck mass, potentially progressing to exert pressure on the trachea and esophagus and giving rise to compressive symptoms. MNG is a common thyroid gland disorder; however, retropharyngeal goiter is considered rare with few reported cases. We report the cases of two patients who presented to our institution with MNG with retropharyngeal extension: a 62-year-old female patient who presented with a progressive anterior neck mass with dilated neck veins; and a 49-year-old male who presented with a painless anterior neck mass. Both patients successfully underwent total thyroidectomy with an uneventful postoperative recovery. The clinical presentation of MNG with retropharyngeal extension varies with patients; hence, a high index of suspicion is of the utmost significance. While the retropharyngeal extension does not cause compressive symptoms, it should raise the suspicion of a large retrosternal component.

RESUMO

Background: Over the past ten years, significant transformations have occurred in the healthcare landscape, presenting respiratory therapists (RTs) with a mix of challenges and opportunities. Hence, their perceptions about career progression and job satisfaction will be critical factor in determining the recruitment and retention of RTs. However, there are no studies in the literature that comprehensively assessed these aspects using a reliable and valid measure specific to RTs. Our objective was to develop and psychometrically test a Standardized Questionnaire (SQ) for evaluating RT's overall job satisfaction. Methods: Following consultations with experts and interviews conducted with RTs, a preliminary questionnaire was devised for the purpose of exploratory factor analysis (EFA). The 49 items of the Structured Questionnaire (SQ) were used for verification of the theorized factor structure and content validity using a confirmatory factor analysis (CFA). Principal Component Analysis (PCA), Structural Equation Modeling (SEM), and Confirmatory Factor Analysis (CFA) for the global fit were done. Cronbach's alpha was performed to estimate the internal consistency. The samples of RTs were collected from India between August 2021 and January 2022. Results: A convenience sample comprising 409 respiratory therapists (RTs) employed in India participated in the survey conducted from June 2021 to January 2022. The exploratory factor analysis revealed three factors that explained 61.2 % of the total variance. The confirmatory factor analysis yielded a 3-factor structure (X2/df = 4.4, p < 0.02, standardized root-mean-square residual = 0.05, goodness of fit index = 0.94, comparative fit index = 0.98). The Cronbach's alpha was 0.94 for the total scale. Conclusions: Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) are becoming more prevalent, especially in the development and psychometric evaluation of instruments. This Structured Questionnaire is a reliable and valid tool that has utility for assessing perceptions, satisfaction, and attitude among Respiratory Therapists and for making comparisons of similar psychometric measures.

RESUMO

Osteochondromyxoma (OMX) is an extremely rare bone tumor and has been classified by the World Health Organization as a benign chondrogenic bone tumor. The tumor can be associated with Carney complex which is a rare autosomal dominant syndrome. The clinical presentation of the patient depends primarily on the location and the size of the tumor. It has an excellent prognosis with complete surgical excision. Here, in this case, we present a young female patient diagnosed with OMX without carney complex and underwent complete endoscopic surgical excision.

RESUMO

Background: Performance evaluation in the allied healthcare education sector is complex, making it essential for policymakers and managers to approach it comprehensively and thoughtfully to understand their performance. Hence, the development and monitoring of Key Performance Indicators (KPIs) in this domain must be considered one of the key priorities for the policymakers in AHIs. Aim: This study aims to develop a framework for the AHIs to extract and profile the indicators, measure, and report the results appropriately. Methods: The authors adopted a general review of the literature approach to study the primary goals of the institutional KPI framework, emphasizing the need for benchmarking while implementing KPIs and how to track performance using a KPI dashboard. Results: The study provides the scope, relevant KPI categories, and a list of KPIs for evaluating the effectiveness of allied healthcare programs. The study findings also emphasized the need for benchmarking the KPIs and establishing a KPI dashboard while measuring and monitoring performance. Conclusion: KPIs are considered an invaluable tool that contributes immensely to the performance monitoring process of AHIs, irrespective of the specialties. This helps to identify and guide AHIs for developing KPIs and the associated minimum data set to measure organizational performance and monitor the quality of teaching and learning. In addition, the KPI framework reported in this study is a tool to assist performance monitoring that can subsequently contribute to the overall quality of AHIs.

RESUMO

Background: Patients with inflammatory bowel disease (IBD) may also experience extraintestinal manifestations (EIMs), which can affect various organ systems, and their occurrence is based on disease activity. Objectives: To determine the prevalence of EIMs and their most common types among IBD patients from Saudi Arabia. Materials and Methods: This retrospective study included all IBD patients aged 14-80 years who visited the Gastroenterology and Hepatology clinics at King Fahad Medical City, Riyadh, between February 2017 and December 2022. The collected data included demographic characteristics, disease characteristics, EIMs, and treatment. Results: The study included 578 IBD patients, of which 65 (11.2%) had at least one EIM, with primary sclerosing cholangitis (46.2%) and sacroiliitis (16.9%) being the most common. Patients with ulcerative colitis were more likely to have EIMs than those with Crohn's disease (15.1% vs. 9%; P = 0.026). Patients with ileocolonic (L3) Crohn's disease reported a higher prevalence of EIMs (7.5%) than those with other disease locations (P = 0.012), while in patients with ulcerative colitis, those with extensive colitis (E3) reported higher prevalence of EIMs (19.2%) (P = 0.001). Patients receiving 6 MP had a significantly high prevalence of EIMs (P = 0.014). Conclusion: The prevalence of extraintestinal manifestations among IBD patients in Saudi Arabia is 11.2%. These findings suggest the need for clinicians to screen for EIMs and manage them early. Further research is needed to understand the mechanisms underlying EIMs for the development of more effective treatments.

RESUMO

In adults, vallecular cysts are usually asymptomatic but can present with respiratory and gastrointestinal manifestations. A 45-year-old man presented with a four-month progressive history of dysphonia, dysphagia to solid, snoring, choking, apnea, and aspiration. On examination, the patient was vitally stable with no remarkable local and physical examination. Flexible nasoendoscopy, computer tomography, and subsequent micro-laryngoscopy revealed a non-pulsating, non-congested 3 x 2 cm cyst obscuring vocal cord visualization. The cyst was removed completely by cold and hot techniques and was sent for biopsy. This case report presents the successful management of a symptomatic vallecular cyst through electrocautery.

RESUMO

Cancer immunotherapy targeting adaptive immune cells has been attracting considerable interest due to its great success in treating multiple cancers. Recently, there is also increasing interest in agents that can stimulate innate immune cell activities. Immune checkpoint inhibitors targeting innate immune cells can block inhibitory interactions ('don't eat me' signals) between tumor cells and phagocytes. CD47 is a transmembrane protein overexpressed in various cancers and acts as a potent 'do not eat me' signal that contributes to the immune evasion of cancer cells. Anti-CD47 peptides that can bind to CD47 and block CD47/SIRPα interaction were discovered using a novel phage display biopanning strategy. Anti-CD47 peptides enhanced the macrophage-mediated phagocytosis of NCI-H82 tumor cells in vitro. Unlike anti-CD47 antibodies, these peptides do not induce the agglutination of RBCs. Moreover, anti-CD47 peptides exhibit high specificity for MC-38 cancer cells expressing CD47. CMP-22 peptide showed the ability to increase the antitumor activity of doxorubicin and extends the survival of CT26 tumor-bearing mice. The discovered anti-CD47 peptides can be considered potential candidates for cancer immunotherapy by blocking the CD47/SIRPα interaction, especially in combination with chemotherapy, to elicit synergistic effects.

RESUMO

INTRODUCTION: Pancreatitis is an inflammation of the pancreas. The pancreas is a flat, elongated gland situated in the upper abdomen, beyond the stomach. It produces digestive enzymes and hormones that regulate glucose absorption in the body. Pancreatitis can be acute, developing rapidly and lasting for several days, or chronic, persisting over an extended period and affecting specific individuals. While treatment can improve mild cases of pancreatitis, severe cases can be fatal. METHOD: This study utilizes a cross-sectional survey design with 549 participants, allowing data collection from a representative sample of Tabuk City's adult population. RESULTS: The participants' knowledge about the risk factors and symptoms of pancreatitis was inadequate. Among those who did not receive any information about pancreatitis and its risk factors, the count was 352 (64.1%). On the other hand, there was increased awareness of pancreatitis and its risk factors, which would lead to early detection and prevention. A total of 483 participants (88%) expressed adequate agreement, and 305 participants (55.6%) demonstrated an adequate response regarding seeking medical attention if they experienced any symptoms of pancreatitis. CONCLUSION: Our findings revealed a lack of knowledge about the risk factors and symptoms of pancreatitis. Furthermore, there was inadequate awareness regarding governmental initiatives or programs that support access to pancreatitis knowledge and awareness in Tabuk City.

RESUMO

Background: Patients with inflammatory bowel disease (IBD) are at a higher risk of cytomegalovirus (CMV) colitis because of their immunocompromised status. There are no studies from Saudi Arabia regarding the prevalence of CMV colitis in patients with IBD. Objective: To determine the prevalence, characteristics, and risk factors of CMV colitis in patients with IBD in Riyadh, Saudi Arabia. Materials and Methods: This retrospective study included patients with a confirmed diagnosis of IBD (aged 14-75 years) who were followed up at King Fahad Medical City, a referral care center in Riyadh, between January 2016 and December 2021; patients with indeterminate colitis or incomplete medical records were excluded. Results: A total of 341 patients with IBD were included, of which 236 (72.2%) had Crohn's disease (CD) and 105 (27.8%) had ulcerative colitis (UC). Qualitative CMV PCR was done for 192 patients (60 UC and 132 CD patients), of which 14 patients were positive for CMV colitis (7.3%), and all positive CMV colitis cases were among UC patients (23.3%). However, the hematoxylin and eosin (H and E) stain and immunohistochemistry were negative for all patients. Most patients with CMV colitis were on steroids (71.4%), had at least one flare-up (64.3%), and were on biologic treatment (71.4%). Significant predictors of CMV colitis were hemoglobin (OR: 0.7; 95% CI: 0.51-0.96), albumin (OR: 0.88; 95% CI: 0.78-0.98), and C-reactive protein (OR: 1.03; 95% CI: 1.01-1.06) levels. Conclusion: This study found that the prevalence of CMV colitis was 7.3% among patients with IBD, and no case was diagnosed in patients with CD. In addition, as all cases diagnosed using qualitative CMV PCR were negative on H and E stain and immunohistochemistry, there is need for large-scale studies to improve the diagnosis of CMV colitis.

RESUMO

Background: Few studies have looked at how SARS-CoV-2 affects pulmonary function, exercise capacity, and health-related quality of life over time. The purpose of this study was to evaluate these characteristics in post COVID-19 subjects 1 year after recovery. Methods: The study included two groups. The case group included post COVID-19 subjects who had recovered after a year, and the control group included healthy participants who had never tested positive for COVID-19. Results: The study screened 90 participants, 42 of whom met the eligibility criteria. The findings revealed that the majority of post COVID-19 subjects had relatively normal lung function 1-year post-recovery. A significant reduction in DLCO (B/P%) was observed in the case group vs. control. The exercise capacity test revealed a clinically significant difference in distance walked and a significant difference in the dyspnea post-walk test in the case group compared to the control group. The case group's health-related quality of life domain scores were significantly affected in terms of energy/fatigue, general health, and physical function. Conclusions: The post COVID-19 subjects were shown to have well-preserved lung function after 1 year. However, some degree of impairment in diffusion capacity, exercise capacity, and health-related quality of life remained.

RESUMO

Background: Smoking behavior has been associated with poor academic performance among adult students worldwide. However, the detrimental effect of nicotine dependence on several students' academic achievement indicators is still unclear. This study aims to assess the impact of smoking status and nicotine dependence on grade point average (GPA), absenteeism rate and academic warnings among undergraduate health sciences students in Saudi Arabia. Methods: A validated cross-sectional survey was conducted, in which, participants responded to questions evaluated cigarette consumption, urge to consume and dependency, learning performance, days of absentees, and academic warnings. Results: A total of 501 students from different health specialties have completed the survey. Of whom, 66% were male, 95% ranging between the age of 18-30 years old, and 81% reported no health issues or chronic diseases. Current smokers estimated to be 30% of the respondents, of which 36% revealed smoking history of 2-3 years. The prevalence of nicotine dependency (high to extremely high) was 50%. Overall, smokers had significantly lower GPA, higher absenteeism rate, and higher number of academic warnings when compared to nonsmokers (p<0.001). Heavy smokers demonstrated significantly less GPA (p=0.036), higher days of absences (p=0.017), and more academic warnings (p=0.021) compared to light smokers. The linear regression model indicated a significant association between smoking history (increased pack-per-year) and poor GPA (p=0.01) and increased number of academic warning last semester (p=0.01), while increased cigarette consumption was substantially linked with higher academic warnings (p=0.002), lower GPA (p=0.01), and higher absenteeism rate for last semester (p=0.01). Conclusion: Smoking status and nicotine dependence were predictive of worsening academic performance, including lower GPA, higher absenteeism rate and academic warnings. In addition, there is a substantial and unfavorable dose-response association between smoking history and cigarette consumption with impaired academic performance indicators.

RESUMO

BACKGROUND: There is a concerning lack of representative data on chronic obstructive pulmonary disease (COPD) awareness in Saudi Arabia, and a significant proportion of the population is vulnerable to developing a smoking habit, which is a major risk factor for the disease. METHODS: Population-Based Survey of 15,000 people was conducted to assess the public knowledge and awareness of COPD across Saudi Arabia from October 2022 to March 2023. RESULTS: A total of 15002 responders completed the survey, with a completion rate of 82%. The majority 10314 (69%) were 18-30 year and 6112 (41%) had high school education. The most common comorbidities among the responders were depression (7.67%); hypertension (6%); diabetes (5.77%) and Chronic Lung Disease (4.12%). The most common symptoms were dyspnea (17.80%); chest tightness (14.09%) and sputum (11.19%). Among those who complains of any symptoms, only 16.44% had consulted their doctor. Around 14.16% were diagnosed with a respiratory disease and only 15.56% had performed pulmonary function test (PFT). The prevalence of smoking history was 15.16%, in which current smokers were 9.09%. About 48% of smokers used cigarette, 25% used waterpipe and around 27% were E-cigarette users. About 77% of the total sample have never heard about COPD. Majority of current smokers (73.5%; 1002), ex-smokers (68%; 619), and non-smokers (77.9%; 9911) are unaware of COPD, p value <0.001. Seventy five percent (1028) of the current smokers and 70% (633) of the ex-smokers have never performed PFT, p value <0.001. Male, younger age (18-30 years), higher education, family history of respiratory diseases, previous diagnosis of respiratory disease, previous PFT, and being an ex-smokers increases the odds of COPD awareness, p-value <0.05. CONCLUSION: There is a significantly low awareness about COPD in Saudi Arabia, especially among smokers. A nationwide approach must include targeted public awareness campaigns, continued healthcare professional education, community-based activities encouraging diagnosis and early detection, advice on smoking cessation and lifestyle changes, as well as coordinated national COPD screening programs.

RESUMO

The result of the movement restrictions during the COVID-19 pandemic was an impromptu and abrupt switch from in-person to online teaching. Most focus has been on the perception and experience of students during the process. The aim of this international survey is to assess staffs' perspectives and challenges of online teaching during the COVID-19 lockdown. Cross-sectional research using a validated online survey was carried out in seven countries (Brazil, Saudi Arabia, Jordan, Indonesia, India, the United Kingdom, and Egypt) between the months of December 2021 and August 2022, to explore the status of online teaching among faculty members during the COVID-19 pandemic. Variables and response are presented as percentages while logistic regression was used to assess the factors that predict levels of satisfaction and the challenges associated with online instruction. A total of 721 response were received from mainly male (53%) staffs. Most respondents are from Brazil (59%), hold a Doctorate degree (70%) and have over 10 years of working experience (62%). Although, 67% and 79% have relevant tools and received training for online teaching respectively, 44% report that online teaching required more preparation time than face-to-face. Although 41% of respondents were uncertain about the outcome of online teaching, 49% were satisfied with the process. Also, poor internet bandwidth (51%), inability to track students' engagement (18%) and Lack of technical skills (11.5%) were the three main observed limitations. Having little or no prior experience of online teaching before the COVID-19 pandemic [OR, 1.58 (95% CI, 1.35-1.85)], and not supporting the move to online teaching mode [OR, 0.56 (95% CI,0.48-0.64)] were two main factors independently linked with dissatisfaction with online teaching. While staffs who support the move to online teaching were twice likely to report no barriers [OR, 2.15 (95% CI, 1.61-2.86)]. Although, relevant tools and training were provided to support the move to online teaching during COVID-19 lockdown, barriers such as poor internet bandwidth, inability to track students' engagement and lack of technical skills were main limitations observed internationally by teaching staffs. Addressing these barriers should be the focus of higher education institution in preparation for future disruptions to traditional teaching modes.

RESUMO

Obstructive sleep apnoea is a common condition associated with cardiovascular risk. Continuous positive airway pressure (CPAP) is an effective treatment but is associated with nasal side-effects, which hinder compliance and may result from inflammation. We investigated whether CPAP was pro-inflammatory to human subjects in vivo, and to cultured bronchial epithelial cells in vitro. In vivo, we further investigated whether induction of nasal inflammation was associated with the development of systemic inflammation, nasal symptoms and changes in nasal mucociliary clearance. In vitro, CPAP resulted in cytokine release from cultured BEAS-2B cells in a time- and dose (pressure)-dependent manner. In vivo, CPAP resulted in dose-dependent upregulation of nasal inflammatory markers associated with the development of nasal symptoms, and reduced mucociliary clearance. CPAP also upregulated selected markers of systemic inflammation. CPAP results in dose-dependent release of inflammatory cytokines from human epithelial cells in vitro and in vivo. In vivo responses were associated with systemic inflammation, reductions in nasal mucociliary function and the development of nasal symptoms. This emphasises the need for novel strategies to reduce nasal inflammation and therefore aid compliance.

RESUMO

BACKGROUND: Chordoma are rare tumors of the axial skeleton. The treatment gold standard is surgery, followed by particle radiotherapy. Total resection is usually not achievable in skull base chordoma (SBC) and high recurrence rates are reported. Ectopic recurrence as a first sign of treatment failure is considered rare. Favorable sites of these ectopic recurrences remain unknown. METHODS: Five out of 16 SBC patients treated with proton therapy and surgical resection developed ectopic recurrence as a first sign of treatment failure were critically analyzed regarding prior surgery, radiotherapy, and recurrences at follow-up imaging. RESULTS: Eighteen recurrences were defined in five patients. A total of 31 surgeries were performed for primary tumors and recurrences. Seventeen out of eighteen (94%) ectopic recurrences could be related to prior surgical tracts, outside the therapeutic radiation dose. Follow-up imaging showed that tumor recurrence was difficult to distinguish from radiation necrosis and anatomical changes due to surgery. CONCLUSIONS: In our cohort, we found uncommon ectopic recurrences in the surgical tract. Our theory is that these recurrences are due to microscopic tumor spill during surgery. These cells did not receive a therapeutic radiation dose. Advances in surgical possibilities and adjusted radiotherapy target volumes might improve local control and survival.

RESUMO

Background Pituitary apoplexy (PA) is a rare complication of pituitary tumors that can present with a myriad of symptoms, including sudden onset cranial nerve deficits. After patient stabilization and hormone replacement, surgical decompression is often recommended. The timing of surgical decompression remains controversial. In this case series, we describe our institutional experience pertaining to the cranial nerve recovery in patients who underwent endoscopic endonasal transsphenoidal (EETS) surgery for PA while evaluating outcome based on tumor stage using the suprasellar infrasellar parasellar anterior posterior (SIPAP) classification. Design Present study is a single-institution retrospective cohort. Methods A retrospective review of all EETS cases for pituitary tumor resection between November 2009 and August 2018. Queries of the hospital database were completed by trained personnel to identify cases of PA treated using the EETS approach. Baseline characteristics, tumor type, endocrine data, and SIPAP classification based on preoperative magnetic resonance imaging (MRI) and operation characteristics were extracted from medical records. Postoperative results were extracted for the duration of the follow-up period available for each patient. Results Fifteen cases of PA were identified. Patient follow-up period was a mean of 30 months. The cranial nerve deficits present at admission were visual deficit (33%); unilateral third nerve palsy (47%) and unilateral sixth nerve palsy (27%). No fourth nerve palsies were observed. Following EETS, 60% of patients with preoperative visual deficit had normal visual fields. For those with third and sixth nerve palsies preoperatively, 43 and 75%, respectively, had return to normal function postoperatively. SIPAP tumor characteristics were not related to postoperative cranial nerve recovery. Conclusion In this series of surgically treated patients with pituitary apoplexy, all cranial nerve deficits normalized or improved following surgery. The tumor SIPAP classification was not associated with patient outcome. Though in a small series, the presented results suggest surgical treatment is beneficial for these patients.
