Prevalence, factors associated and management of needle phobia among the general population in Saudi Arabia and Egypt.

OBJECTIVE: This study aims to assess the prevalence of needle phobia among Saudi and Egyptian adult populations. In addition, underlying causes and strategies that can be utilized to address needle fear were investigated. METHODS: A cross-sectional online survey study was conducted in Saudi Arabia and Egypt between 1 May and 30 June 2023. Participants aged 18 years and above and living in Saudi Arabia and Egypt were eligible to complete the survey. Participants were invited to participate in this study through social media platforms (Facebook, X, Snapchat, and Instagram). A convenience sampling technique was used to recruit the study participants. A 21-item questionnaire consisting of four sections including a Likert scale score was used to answer the research objectives. Numeric data were presented as mean ± SD. For categorical variables, percentages were used. Comparison between groups were made by Student's t-test or Mann Whitney test according to data distribution. Chi squared tests for categorical values were conducted. A binary logistic regression analysis was conducted to investigate factors associated with needle phobia. RESULTS: A total of 4065 participants were involved in this study (Saudi Arabia: 2628 and Egypt: 1437). Around one-third of the study participants (36.5%) confirmed that they have needle phobia. Most of the study participants (81.1%) reported that they have had needle phobia since they were under 18 years of age. Pain, general anxiety, and fear of making a mistake during the procedure were the most commonly reported contributors for fear of needles during or before a medical procedure. Around 15.8% of the study participants reported that they have tried to get rid of phobia from needles. Non-surgical alternatives (such as oral medications and patches) and using smaller/thinner needles were the most commonly reported interventions that reduced fear of needles. Binary logistic regression analysis identified that females, those who are aged (41-50 years), widowed, those with bachelor's degrees and higher education, and those unemployed were more likely to have needle phobia compared to others. CONCLUSION: Our study highlighted the high prevalence of needle fear within an adult population in Egypt and Saudi Arabia. Females, those who are aged (41-50 years), those widowed, those with higher education degrees, those unemployed, those working in the health sector and people with low income were more likely to have needle phobia compared to others.

Asthma medication adherence, control, and psychological symptoms: a cross-sectional study.

BACKGROUND: Nonadherence to therapies and psychological disorders are associated with poor asthma control. This study aims to assess the prevalence of anxiety and depressive symptoms, asthma control, and adherence to inhalers and to investigate whether there is an association of anxiety and depressive symptoms with adherence to inhalers and asthma control. METHODS: We measured anxiety and depressive symptoms using the Hospital Anxiety and Depression Scale in patients with asthma. Asthma Control Test and the 10-Item Test of Adherence to Inhalers Scale were used to assess levels of asthma control adherence to inhalers, respectively. Univariate and multivariate regression models assessed the associations of anxiety and depressive symptoms with adherence to inhalers and asthma control. RESULTS: A total of 287 patients completed the study, of whom 72% were female. The mean ± SD age and body mass index of our study population were 44 ± 13 years and 29 ± 7.2 kg/m2, respectively. Poor adherence to inhaler use was highly prevalent (49.8%; 95% CI: 43.8 to 55.7). The prevalence of anxiety, depression and poor asthma control was 27.2% (95% CI: 22.1 to 32.7), 20.9% (95% CI: 16.3 to 26.1), and 22.7% (95% CI: 17.9 to 27.9), respectively. We found a negative relationship between asthma control and anxiety, and depressive symptoms (adjusted ß: -0.25; 95% CI: -0.36 to -0.14; p < 0.001 and adjusted ß: -0.29; 95% CI: -0.40 to -0.18; p < 0.001, respectively). A negative relationship was also observed between adherence to inhalers and anxiety and depressive symptoms (adjusted ß: -0.34; 95% CI: -0.46 to -0.22; p < 0.001 and adjusted ß: -0.36; 95% CI: - 0.48 to - 0.24; p < 0.001, respectively). CONCLUSIONS: The high prevalence of uncontrolled asthma symptoms and poor adherence to inhalers and their impact on anxiety and depression levels among patients with asthma point to the need for early screening for psychological symptoms and recognition of nonadherence as part of asthma assessment and management plan in primary care in Saudi Arabia to avoid further worsening of asthma symptoms. Further studies are needed to explore the effectiveness of specific psychoeducational interventions and investigate the long-term impact of early psychological symptom detection on asthma outcomes.

Clinical Practice of High-Flow Nasal Cannula Therapy in ARDS Patients: A Cross-Sectional Survey of Respiratory Therapists.

Background: High-flow nasal cannula (HFNC) is an essential non-invasive oxygen therapy in acute respiratory distress syndrome (ARDS) patients. Despite its wide use, research assessing the knowledge, practice, and barriers to using HFNC among respiratory therapists (RT) is lacking. Methods: A cross-sectional questionnaire was conducted among RTs in Saudi Arabia between December 19, 2022, and July 15, 2023. Data were analyzed as means and standard deviation or frequency and percentages. A Chi-square test was used to compare the differences between groups. Results: A total of 1001 RTs completed the online survey. Two-thirds of the respondents 659 (65.8%) had received training in using HFNC and 785 (78.4%) had used HFNC in clinical settings. The top conditions for HFNC indication were COVID-19 (78%), post-extubation (65%), and do-not-intubate patients (64%). Participants strongly agreed that helping maintain conversation and eating abilities (32.95%) and improving shortness of breath (34.1%) were advantages of HFNC. Surprisingly, 568 (57%) of RT staff did not follow a protocol for HFNC with ARDS patients. When starting HFNC, 40.2% of the participants started with FiO2 of 61% to 80%. Additionally, high percentages of RT staff started with a flow rate between 30 L/minute and 40 L/minute (40.6%) and a temperature of 37°C (57.7%). When weaning ARDS patients, 482 (48.1%) recommended first reducing gas flow by 5-10 L/minute every two to four hours. Moreover, 549 (54.8%) believed that ARDS patients could be disconnected from HFNC if they achieved a flow rate of <20 L/minute and FiO2 of <35%. Lack of knowledge was the most common challenge concerning HFNC implementation. Conclusion: The findings revealed nuanced applications marked by significant endorsement in certain clinical scenarios and a lack of protocol adherence, underscoring the need for uniform, evidence-based guidelines and enhanced training for RTs. Addressing these challenges is pivotal to optimizing the benefits of HFNC across varied clinical contexts.

The prevalence and sociodemographic determinants of tobacco and nicotine use among students in healthcare disciplines in Saudi Arabian universities: a cross-sectional survey.

Background: Tobacco smoking is one of the most significant health-related problems worldwide. However, the prevalence and sociodemographic determinants of tobacco and nicotine use among students on healthcare courses in Saudi Arabia are limited. Methods: This cross-sectional study used a questionnaire that was distributed via SurveyMonkey between November 2022 and June 2023 to all student universities offering healthcare courses. Data are presented as frequency and percentages. The associated sociodemographic factors with current tobacco and nicotine use were subjected to logistic regression. Results: Overall, 5,012, of whom 3,872 (77.25%) were males, responded to the online survey. The prevalence of current tobacco and nicotine use was 3,553 (71%). The majority of users used electronic nicotine delivery systems (1,622: 32.36%). The current use of cigarettes (AOR: 1.75 (1.42 to 2.15)), e-cigarettes (AOR: 1.17 (1.01 to 1.37)), and smokeless tobacco substances (AOR: 1.35 (1.02 to 1.90)) were more pronounced among males compared to female students. However, the current use of a hookah was less among males (AOR: 0.74 (95% CI: 61 to 0.91)). Smoking cigarettes was practiced less among students living in other regions compared to the Central Region. However, smokeless tobacco substances seem to be more prevalent in the Western, Southern, and Northern Regions, (AOR: 1.57 (95% CI: 1.09 to 2.26)), (AOR: 1.43 (95% CI: 1.04 to 1.95)), and (AOR: 1.57 (95% CI: 1.09 to 2.26)), respectively. Conclusion: Smoking is prevalent among students in the healthcare disciplines, with electronic nicotine delivery systems being the most used product. Several sociodemographic factors were associated with higher tobacco or nicotine use.

Prevalence of asthma triggers and control status among pediatric asthmatic patients in Saudi Arabia.

AIM: This study aims to assess the prevalence of asthma triggers and control status among pediatric asthmatic patients in Saudi Arabia. METHODS: From October 2015 to March 2016, an Arabic version of the Asthma Trigger Inventory questionnaire and asthma control test (ACT) were distributed to 200 parents of children diagnosed with asthma at the pulmonary clinic of King Fahad Medical City in Riyadh, Saudi Arabia. Data were collected and analyzed using the Statistical Package for Social Sciences (SPSS) software version 29. Descriptive statistics of the participants were presented in frequencies, percentages, means, and standard deviations for categorical variables. RESULTS: The survey data revealed that the most prevalent asthma triggers among pediatric asthmatic children in Saudi Arabia were Arabic incense (Bakhour) with a mean score of 3.76 (±1.3), followed by being excited 3.70 (±1.5), and stress at home 3.58 (±1.4). Furthermore, the degree of asthma control among children with asthma in Saudi Arabia was 72.0% with a mean score of 17.7 (±4.7) for the ACT, indicating partial degree of asthma. CONCLUSIONS: Arabic incense (Bakhour) and psychological stimuli emerged as significant determinants of asthma triggers in Saudi Arabian children diagnosed with asthma. Further studies are warranted to elucidate the physiological mechanisms underpinning the response to Arabic incense (Bakhour).

A population-based study of 15,000 people on Knowledge and awareness of lung cancer symptoms and risk factors in Saudi Arabia.

Background: Lung cancer is currently the most fatal form of cancer worldwide, ranking as the fourth most prevalent type in Saudi Arabia, particularly among males. This trend is expected to increase with growing population, lifestyle changes, and aging population. Understanding the awareness of the Saudi population regarding the risk factors and symptoms of lung cancer is necessary to attenuate the predicted increase in cases. Method: A cross-sectional, population-based survey was performed using a previously validated questionnaire (Lung CAM). Multiple linear regression analysis was used to assess variables associated with deficiency in knowledge and awareness of risk factors and symptoms of lung cancer. Results: Majority of the 15,099 respondents were male (65%), aged between 18 and 30 years (53%), 50% of which were educated up to a bachelor's degree level. Overall awareness of lung cancer signs and symptoms was 53%, with painful cough and coughing up blood being the best-known symptoms. Conversely, persistent shoulder pain (44%) and clubbing fingers (47%) were the least known lung cancer symptoms. Also, 60% of the respondents showed low confidence in identifying the signs and symptoms of lung cancer. The overall awareness of the risk factors for lung cancer development was 74%, with first-hand (74%) and second-hand (68%) smoking being the most known risk factors. However, only ≤ 62% know the other non-smoking risk factors. Awareness of the risk factors and symptoms of lung cancer depended on age, gender, education, marital and employment status (p < 0.001). Conclusion: Public awareness of the risk factors and symptoms of lung cancer in Saudi Arabia is inadequate and heavily dependent on education and socio-economic status. Awareness can be improved through campaigns to raise awareness about other lesser-known lung cancer risk factors and symptoms.

Spirometry profiles of overweight and obese individuals with unexplained dyspnea in Saudi Arabia.

Background: Obesity is a common cause of dyspnea. However, the impacts of obesity on spirometry parameters, particularly among individuals with unexplained dyspnea, have not been well investigated. Objectives: This study aimed to explore the prevalence of overweight and different classes of obesity and their effect on spirometry parameters among subjects with unexplained dyspnea in Saudi Arabia. Methods: We conducted a retrospective electronic medical record review of individuals with unexplained dyspnea who visited our pulmonary clinic between January 2016 and December 2022 and assessed the association of body mass index (BMI) with spirometry parameters. After we classified the subjects based on their BMI values, we determined the impacts of increased BMI on spirometry parameters. Results: The sample included a total of 978 subjects with unexplained dyspnea. The prevalence of overweight and obesity among our study sample was high (33 % and 47 %, respectively). All spirometry parameters: forced vital capacity (FVC) L, forced expiratory volume in 1 s (FEV1) L, forced expiratory flow at 25-75 % (FEF 25-75 %) L/sec and peak expiratory flow (PEF) L/sec were significantly lower in obese individuals with dyspnea compared to normal weight subjects. In addition, our findings showed a negative correlation between BMI and FVC, FEV1, FEF 25-75 %, and PEF. Conclusion: The high prevalence of obesity and overweight and the impairment of lung function because of high body weight among subjects with dyspnea point to the need for routine assessment and the evaluation of nutritional status in primary health care facilities for early intervention.

Awareness and practice of airway pressure release ventilation mode in acute respiratory distress syndrome patients among nurses in Saudi Arabia.

BACKGROUND: This study aimed to assess the knowledge and current practice of using the airway pressure release ventilation (APRV) mode with acute respiratory distress syndrome (ARDS) patients and identify barriers to not using this mode of ventilation among nurses who work in critical areas in Saudi Arabia. METHODS: Between December 2022 and April 2023, a cross-sectional online survey was disseminated to nurses working in critical care areas in Saudi Arabia. The characteristics of the respondents were analyzed using descriptive statistics. Percentages and frequencies were used to report categorical variables. RESULTS: Overall, 1,002 nurses responded to the online survey, of whom 592 (59.1%) were female. Only 248 (24.7%) nurses had ever used APRV mode, whereas only 229 (22.8%) received training on APRV mode. Moreover, 602 (60.0%) nurses did not know whether APRV was utilized in their hospital. Additionally, 658 (65.6%) nurses did not know whether APRV mode was managed using a standard protocol. Prone positioning was the highest recommended intervention by 444 (43.8%) when a conventional MV failed to improve oxygenation in patients with ARDS. 323 (32.2%) respondents stated that the P-high should be set equal to the plateau pressure on a conventional ventilator, while 400 (39.9%) said that the P-low should match PEEP from a conventional ventilator. Almost half of the respondents (446, 44.5%) stated that the T-high should be set between 4 and 6 s, while 415 (41.4%) said that the T-low should be set at 0.4 to 0.8 s. Over half of the nurses (540, 53.9%) thought that the maximum allowed tidal volume during the release phase should be 4-6 ml/kg. Moreover, 475 (47.4%) believed that the maximum allowed P-high setting should be 35 cm H2O. One-third of the responders (329, 32.8%) stated that when weaning patients with ARDS while in APRV mode, the P-high should be reduced gradually to reach a target of 10 cm H2O. However, 444 (44.3%) thought that the T-high should be gradually increased to reach a target of 10 s. Half of the responders (556, 55.5%) felt that the criteria to switch the patient to continuous positive airway pressure (CPAP) were for the patient to have an FiO2 ≤ 0.4, P-high ≤ 10 cm H2O, and T-high ≥ 10 s. Lack of training was the most common barrier to not using APRV by 615 (61.4%). CONCLUSION: The majority of nurses who work in critical care units have not received sufficient training in APRV mode. A significant discrepancy was observed regarding the clinical application and management of APRV parameters. Inadequate training was the most frequently reported barrier to the use of APRV in patients with ARDS.

Obesity Prevalence and Association with Spirometry Profiles, ICU Admission, and Comorbidities Among Patients with COPD: Retrospective Study in Two Tertiary Centres in Saudi Arabia.

Background: Obesity is common among chronic obstructive pulmonary disease (COPD) patients and is associated with an increase in acute exacerbation episodes. However, data on obesity's impact on and association with clinical outcomes among patients with COPD are limited. This study aimed to determine overweight and obesity prevalence and associations with spirometry profiles, intensive care unit (ICU) admission, and comorbidities in patients with COPD. Methods: In this retrospective cohort study, we reviewed the electronic health records of adult individuals diagnosed with COPD who visited the studied pulmonary clinics between 1 January 2018 and 31 December 2022 and then collected key demographic variables and relevant clinical outcomes and comorbidities. Results: A total of 474 patients with COPD were included in the final analysis, of whom 60% were male. The occurrences of overweight and obesity were 32.7% and 38.2%, respectively. The presence of comorbidities was high in obese patients (78.4%), followed by overweight patients (63.8%) with COPD. Obese and overweight patients had the highest ward admission rates (38.3% and 34.2%, respectively). ICU admissions were higher in obese and overweight patients (16% and 12%, respectively) compared with normal-weight patients (9%). Although no significant correlation was found between body mass index and spirometry parameters, comorbidities and ICU admission were linked to overweight and obesity in COPD patients (AOR: 1.82 95% CI: 1.15 to 2.86 and AOR: 3.34 95% CI 1.35 to 8.22, respectively). Conclusion: Our findings imply that obesity in COPD is prevalent and is associated with adverse clinical outcomes including a greater number of comorbidities and higher rates of hospitalization and admission to ICUs although no associations were found between body weight and spirometry parameters. Further studies are needed to assess whether implementing and optimising obesity screening and management at an early stage in COPD can prevent further deterioration.

Knowledge and practice of using airway pressure release ventilation mode in ARDS patients: A survey of physicians.

Background: Limited data is available on awareness and clinical management of the airway pressure release ventilation (APRV) mode of ventilation for acute respiratory distress syndrome (ARDS) patients among physicians who work at in adult critical areas. This study aimed to assess the knowledge and current practice of using APRV mode with ARDS patients and identify barriers to not using this mode of ventilation among physicians who work in adult critical areas in Saudi Arabia. Methods: Between November 2022 and April 2023, a cross-sectional online survey was disseminated to physicians who work in adult critical areas in Saudi Arabia. The characteristics of the respondents were analyzed using descriptive statistics. Percentages and frequencies were used to report categorical variables. Results: Overall, 498 physicians responded to the online survey. All responders (498, 100 %) reported that APRV is indicated in patients with ARDS, but 260 (52.2 %) did not know if there was an institutionally approved APRV protocol. Prone positioning was the highest recommended intervention by 164 (33.0 %) when a conventional MV failed to improve oxygenation in patients with ARDS. 136 (27.3 %) responders stated that the P-high should be set equal to the plateau pressure on a conventional ventilator while 198 (39.8 %) said that P-low should be 0 cmH2O. Almost half of (229, 46.0 %) responders stated that the T-high should be set between 4 and 6 s, while 286 (57.4 %) said that the T-low should be set at 0.4-0.8 s. The maximum allowed tidal volume during the release phase should be 4-6 ml/kg. Moreover, just over half (257, 51.6 %) believed that the maximum allowed P-high setting should be 35 cmH2O. One third of the responders (171, 34.3 %) stated that when weaning patients with ARDS while in APRV mode, the P-high should be reduced gradually to reach a target of 10 cmH2O. However, 284 (36.9 %) thought that the T-high should be gradually increased to reach a target of 10 s. Most responders (331, 66.5 %) felt that the criteria to switch the patient to CPAP would be to have an FiO2 ≤ 0.4, P-high ≤10 cm H2O, and T-high ≥10 s. Lack of training has been the most common barrier to not using APRV by 388 (77.9 %). Conclusion: There is a lack of consensus on the use of APRV mode, probably due to several barriers. While there were some agreements on the management of ventilation and oxygenation, there were variations in the selection of the initial setting of APRV. Education, training, and the presence of standardized protocols may help to provide better management.

The utility of the necessity-concerns framework (NCF) in explaining adherence and parental beliefs about controller medication in Saudi Arabian children with asthma.

OBJECTIVE: This study aims to assess beliefs about asthma controller medications among parents of Saudi Arabian children with asthma and the association between these beliefs and medication adherence using the Necessity-Concerns Framework. METHODS: A cross-sectional survey was provided to parents of children with asthma when they brought their children to routine appointments at local public clinics between May 16 and July 10, 2018. Participants electronically filled out validated Arabic versions of the Medication Adherence Reported Scale (MARS) and Beliefs About Medications Questionnaire (BMQ). Descriptive statistics were used to characterize the study participants, while hierarchical linear regression analysis assessed associations between parental beliefs about controller medications and medication adherence. RESULTS: A total of 381 parents of children with asthma completed the study survey. The vast majority (89%) of study participants were non-adherent to their children's prescribed medications while only 11% were adherent. Additionally, our study revealed a significantly positive association between adherence and parents' beliefs in the necessity of the medication (p < .001), with concerns about the adverse effects of medication being negatively associated with parental adherence. A higher mean score for medication adherence was reported among the ambivalent groups compared to the accepting, indifferent, and skeptical groups. CONCLUSIONS: Medication adherence among parents of children with asthma was relatively low. In addition, necessity beliefs were significantly associated with parental adherence to controller medications for their children with asthma. Further studies are warranted to investigate potential factors contributing to poor parental adherence and develop tailored interventions that support parental medication adherence for their asthmatic children.

The rate of ward to intensive care transfer and its predictors among hospitalized COPD patients, a retrospective study in a local tertiary center in Saudi Arabia.

OBJECTIVE: To investigate the prevalence of intensive care unit (ICU) admission and its predictors among hospitalized chronic obstructive pulmonary disease (COPD) patients. METHODS: An observational retrospective study was conducted. All patients with a confirmed diagnosis of COPD according to the GOLD guidelines between 28 and 2020 and 1 March 2023 at Al-Noor Specialist Hospital were included in this study. Patients were excluded if a preemptive diagnosis of COPD was made clinically without spirometry evidence of fixed airflow limitation. Descriptive results were presented as frequency (percentage) for categorical variables and mean (SD) for continuous variables and to estimate prevalence of ICU admission. Predictors of ICU admission among hospitalized COPD patients were determined using logistic regression analysis. A SPSS (Statistical Package for the Social Sciences) version 25 was used to perform all statistical analysis. RESULTS: A total of 705 patients with COPD were included in this study. The mean age was 65.4 (25.3) years. Around 12.4% of the hospitalized patients were admitted to the ICD. Logistic regression analysis identified that older age (OR; 1.92, (1.41-2.62)), smoking (OR; 1.60 (1.17-2.19)), and having specific comorbidities (Hypertension (OR; 1.98 (1.45-2.71)), Diabetes mellitus (OR; 1.42 (1.04-1.93)), GERD (OR; 2.81 (1.99-3.96)), Ischemic heart disease (OR; 3.22 (2.19-4.75)), Obstructive sleep apnea syndrome (OR; 2.14 (1.38-3.33)), stroke (OR; 4.51 (2.20-9.26))) were predictors of ICU admissions among patients with COPD. CONCLUSIONS: Our study found that a step-up approach to inpatient COPD management requires admission to the ICU in 12.4%, for which age, smoking status, cardiovascular, and stroke were important predictors. Further clinical research is needed to provide a validated model that can be incorporated into clinical practice to monitor this patient population during their admission and identify at-risk individuals for early transfer to higher acuity settings and intensive care units.

Knowledge, practice, counseling confidence, and intention to use AAR model of smoking cessation among respiratory therapists: A cross-sectional study.

There is a paucity of research on knowledge, practice, counseling confidence, and intention to use ask, advice, and refer (AAR) model of smoking cessation among respiratory therapists (RTs). Thus, we aimed to analyze the characteristics and factors that may influence them. We collected data using online questionnaires from convenience sample of active licensed RTs in Saudi Arabia. We included 206 participants. A descriptive analysis of the demographic information and characteristics of smoking cessation counseling practices and confidence were conducted. Multiple linear regression was used to test whether demographic variables and AAR model components significantly predicted the RTs' calculated cumulative score of tobacco counseling confidence skills. Our results showed a deficiency in tobacco knowledge among RTs. Most RTs did not have certifications or attend lectures or seminars related to tobacco treatment. RTs were unfamiliar with the smoking cessation program contact information and mobile smoking cessation clinics but reported a high tobacco counseling confidence score. Clinical experience (P = .008), familiarity with smoking cessation program contact information (P = .02), inquiry regarding smoking status (P < .001), and advice regarding smoking status (P = .03) significantly predicted tobacco counseling confidence levels in RTs. RT experience, knowledge, and awareness of smoking cessation programs could enhance the confidence level among them in implementing AAR model.

Role of prostanoids, nitric oxide and endothelin pathways in pulmonary hypertension due to COPD.

Pulmonary hypertension (PH) due to chronic obstructive pulmonary disease (COPD) is classified as Group 3 PH, with no current proven targeted therapies. Studies suggest that cigarette smoke, the most risk factor for COPD can cause vascular remodelling and eventually PH as a result of dysfunction and proliferation of pulmonary artery smooth muscle cells (PASMCs) and pulmonary artery endothelial cells (PAECs). In addition, hypoxia is a known driver of pulmonary vascular remodelling in COPD, and it is also thought that the presence of hypoxia in patients with COPD may further exaggerate cigarette smoke-induced vascular remodelling; however, the underlying cause is not fully understood. Three main pathways (prostanoids, nitric oxide and endothelin) are currently used as a therapeutic target for the treatment of patients with different groups of PH. However, drugs targeting these three pathways are not approved for patients with COPD-associated PH due to lack of evidence. Thus, this review aims to shed light on the role of impaired prostanoids, nitric oxide and endothelin pathways in cigarette smoke- and hypoxia-induced pulmonary vascular remodelling and also discusses the potential of using these pathways as therapeutic target for patients with PH secondary to COPD.

Inhaled therapies targeting prostacyclin pathway in pulmonary hypertension due to COPD: systematic review.

Background: Pulmonary hypertension due to chronic obstructive pulmonary disease (COPD) and interstitial lung disease (ILD) is classified as group 3 pulmonary hypertension. Inhaled treprostinil, a prostaglandin I2 analogue also known as prostacyclin, has recently been approved as a first drug for patients with pulmonary hypertension secondary to ILD. However, due to a lack of evidence, no therapies are currently approved for those with COPD-associated pulmonary hypertension. Thus, this systematic review aims to summarise the current evidence to assess the impact of inhaled prostaglandin I2 analogue use on the pulmonary hemodynamics, exercise function, lung function, and gas exchange in patients with pulmonary hypertension due to COPD. Methods: We systematically searched the electronic databases of Medline, Embase, Scopus and Cochrane from inception to 1 February 2023. Studies of adult patients with a confirmed diagnosis of COPD-associated pulmonary hypertension who received inhaled drugs targeting the prostacyclin pathway were included in the systematic review. Case reports, systematic reviews, conference abstracts with no full text, non-full-text articles, non-English manuscripts and book chapters were excluded from this systematic review. A risk-of-bias assessment was carried out for the studies included in this review, using two different Cochrane risk-of-bias tools for randomised and non-randomised clinical trials. Results: A total of four studies met our inclusion criteria and were included in this systematic review. The results of one prospective clinical trial showed an improvement in the pulmonary hemodynamics (e.g., cardiac index, cardiac output and mean pulmonary artery pressure) in response to inhaled prostacyclin use in patients with pulmonary hypertension secondary to COPD. However, the severity of dyspnoea, lung function, exercise capacity and gas exchange were not affected when inhaled prostacyclin was used for patients with COPD-related pulmonary hypertension. Conclusion: This systematic review demonstrated that although inhaled prostacyclin does not seem to improve COPD-related outcomes (e.g., lung function and exercise capacity), short-term use of inhaled prostacyclin has the potential to reduce mean pulmonary artery pressure and pulmonary vascular resistance without impairing ventilation-perfusion mismatch. Further studies with larger sample sizes are warranted. Systematic review registration: CRD42022372803, https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=372803.

Exploring the Relationship Between Stress and Satisfaction During Clinical Training Among Respiratory Therapy Students: A Nationwide Cross-Sectional Survey.

Background: Although clinical training is an important component of healthcare education, it is nevertheless a significant source of stress for students. There is limited information on stress and satisfaction perceived by clinical-level undergraduate students studying respiratory therapy (RT) in Saudi Arabia. Methods: A descriptive, cross-sectional study design with an online questionnaire was employed to conduct this study. Data collection occurred during the academic year 2022-2023 among RT students throughout Saudi Arabia. Patricians responded to demographic questions, the Students Stress Scale and Students Professional Satisfaction questionnaires. Descriptive, inferential, and correlational statistics were used to analyze the collected responses. Results: A total of 1001 undergraduate RT students completed the online survey. RT students and interns had an overall moderate to high stress level (mean (SD); 3.55 (0.49)), while satisfaction was perceived as mild to moderate (mean (SD): 2.56 (0.65)). In addition, 38% of the study participants have considered quitting the RT program. Female students showed higher stress levels in the following domains: inadequate knowledge and training, adverse and embarrassing experiences, clinical supervision, patients' pain, and Education-reality conflict (p<0.005) compared to male students. Additionally, students who considered quitting the RT program revealed higher stress levels in all domains (p<0.005). There were negative correlations between satisfaction and stress domains: inadequate knowledge and training (r = -0.32; p = 0.001), adverse and embarrassing experience (r = -0.31; p = 0.025), close supervision (r = -0.24; p = 0.001), insufficient hospital resources (r = -0.30; p 0.002), patients' pain and suffering (r = 0.28; p = 0.04), and education - reality conflict (r = -0.30; p = 0.001). Conclusion: During clinical training, respiratory therapy students experience moderate to high-stress levels and low satisfaction. There need to be tailored interventions to reduce stress and intention to quit and increase students' clinical experience satisfaction.

Perspectives, practices, and challenges of online teaching during COVID-19 pandemic: A multinational survey.

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.

A nationwide survey of public COPD knowledge and awareness in Saudi Arabia: A population-based survey of 15,000 adults.

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.

Prevalence of Nomophobia and Its Association with Academic Performance Among Physiotherapy Students in Saudi Arabia: A Cross- Sectional Survey.

Background: Nomophobia is common among students in many healthcare disciplines, and its association with academic performance has been explore before. However, there is no available data on its prevalence and association with academic performance among undergraduate physiotherapy (PT) students in Saudi Arabia. Methods: Between 22 December 2022 and 30 January 2023, a cross-sectional survey was conducted by dissemination using an online platform (Survey Monkey). Results: In total, 806 PT students, with males accounting for 494 (61%), responded to the survey. The prevalence of nomophobia among PT students was 98.4% (793). The mean (±SD) of the total NMP-Q items scores was 49 (±17), indicating a mild level of nomophobia. Female PT students had significantly higher nomophobia scores than the males (47 (39-65); 44 (38-52); (p < 0.001)). Non-smokers had significant higher nomophobia scores than smokers (46 (38-61); 44 (38-49); (p = 0.004)). Regarding grade point averages (GPA), the students with a GPA of less than 3.49 had the highest nomophobia score (51 (43-74); p <0.001)). Concerning the stage of their studies, bridging students had the highest nomophobia score (51 (34-76); p = 0.023)). Regarding academic warnings, those who reported no academic warnings had the highest nomophobia score (46 (42-50); p = 0.023)). Finally, regarding study hours, the students who spent ≥ five hours studying per week had the highest nomophobia score (54 (42-68); p < 0.001)). Conclusion: Nomophobia is common among PT students, with the majority experiencing a mild level. Being female, non-smoker, and having a higher academic performance were risk factors associated with higher nomophobia levels.

Assessment of the Current Practice of Managing Depression in Patients with Asthma in Saudi Arabia: Physicians' Views.

Objective: Depression is a common comorbidity in patients with asthma with a significant impact on clinical management. However, little information is available about physicians' perceptions and current practices in identifying and managing depression in individuals with asthma in Saudi Arabia. Thus, this study aims to assess physicians' views and current practices of identifying and managing depression in patients with asthma in Saudi Arabia. Methods: A cross-sectional study was employed. Between September 2022 and February 2023, an online survey was distributed to physicians (general practitioners and family, internal and pulmonary medicine specialists) in Saudi Arabia. Descriptive statistics were performed to analyze the collected responses. Results: Out of 1800 invited participants, a total of 1162 physicians completed the online survey. Nearly 40% of the respondents received adequate training for managing depression. More than 60% of physicians reported that depression interferes with self-management and worsens asthma symptoms, while 50% viewed the importance of regular screening for depression. Less than 40% (n=443) aim to identify depression during patients' visits. Of those, only 20% always screen for depression in asthma patients. Physicians show a low level of confidence when asking patients about their feelings (30%), being able to recognize depression (23%), and knowing if patients have depression (23%). The most common barriers linked to recognizing depression are high workload (50%), lack of time to screen for depression (46%), limited knowledge about depression (42%), and poor training (41%). Conclusion: The rate of recognizing and confidently managing depression in asthmatic patients is significantly low. This is attributed to high workload, poor training, and limited knowledge about depression. There is a need to support psychiatric training and implement a systematic approach to depression detection in clinical settings.
