A replicate crossover trial on the inter-individual variability of sleep indices in response to acute exercise undertaken by healthy men.

STUDY OBJECTIVES: Using the necessary replicate-crossover design, we investigated whether there is inter-individual variability in home-assessed sleep in response to acute exercise. METHODS: Eighteen healthy men (mean(SD): 26(6) years) completed two identical control (8-h laboratory rest, 08:45-16:45) and two identical exercise (7-h laboratory rest; 1-h laboratory treadmill run [62(7)% peak oxygen uptake], 15:15-16:15) trials in randomised sequences. Wrist-worn actigraphy (MotionWatch 8) measured home-based sleep (total sleep time, actual wake time, sleep latency, sleep efficiency) two nights before (nights 1-2) and three nights after (nights 3-5) the exercise/control day. Pearson's correlation coefficients quantified the consistency of individual differences between the replicates of control-adjusted exercise responses to explore: (1) immediate (night 3 minus night 2); (2) delayed (night 5 minus night 2); and (3) overall (average post-intervention minus average pre-intervention) exercise-related effects. Within-participant linear mixed models and a random-effects between-participant meta-analysis estimated participant-by-trial response heterogeneity. RESULTS: For all comparisons and sleep outcomes, the between-replicate correlations were non-significant, ranging from trivial-to-moderate (r range = -0.44 to 0.41, P≥0.065). Participant-by-trial interactions were trivial. Individual differences SDs were small, prone to uncertainty around the estimates indicated by wide 95% confidence intervals and did not provide support for true individual response heterogeneity. Meta-analyses of the between-participant, replicate-averaged condition effect revealed that, again, heterogeneity (τ) was negligible for most sleep outcomes. CONCLUSION: Control-adjusted sleep in response to acute exercise was inconsistent when measured on repeated occasions. Inter-individual differences in sleep in response to exercise were small compared to the natural (trial-to-trial) within-subject variability in sleep outcomes.

Perceived Barriers of Clinical Roles Towards Intensive Care Unit Mobility.

Background: There is overwhelming evidence of improved patient outcomes as a result of early mobilization in the intensive care unit (ICU). However, several barriers of ICU mobility remain understated with reference to clinical roles. The purpose of this study is to investigate the perceived barriers of early mobility of critically ill patients among ICU healthcare providers. Methods: In this cross-sectional study, the Mobilization Attitudes and Beliefs Survey (PMABS-ICU) was administered to ICU healthcare providers using an online survey. The study investigated barriers related to knowledge, attitudes, and behaviors regarding ICU mobility practices. These barriers were compared among different ICU clinical roles. Results: The survey yielded a total number of 214 healthcare providers with 41% female and 59% male. Respiratory therapists reported the highest perceived barriers to ICU mobility (M 39, IQR 36, 43) % compared to physical therapists (who reported the lowest barriers), occupational therapists, nurses, and physicians (p ≤ 0.05). ICU healthcare providers' behavior towards ICU mobility such as perceived benefits and safety is ranked as the primary barrier (M 49, IQR 42, 52) %. Professional experience did not significantly vary among all groups. Conclusion: Our findings highlight that ICU healthcare providers' perceptions, including both potential benefits and safety concerns regarding mobility, are significant barriers to implement mobility practices. ICU mobility barriers should be tackled by providing education and training. A focused effort to include RTs and nurses could advance interdisciplinary ICU mobility practice and reduce associated barriers.

Clinical Outcomes of Aspirin and Clopidogrel among Patients with Chronic Obstructive Lung Disease: Insights from a Meta-Analysis.

(1) Background: Aspirin and clopidogrel have been found helpful in improving clinical outcomes among patients with chronic obstructive lung disease (COPD). However, the evidence on the efficacy of aspirin and/or clopidogrel on clinical outcomes has not been synthesized and summarized in the prior reviews. Hence, we undertook a meta-analysis of the research studies examining the effect of aspirin and/or clopidogrel on varying clinical outcomes among COPD patients; (2) Methods: Using key search terms, we searched databases, including MEDLINE, CINAHL, Google Scholar, and EMBASE to find observational studies and RCTs. Our search was limited to research written in English. We used a random effect model to calculate the 95% confidence intervals and pooled hazard ratio; (3) Results: We included 12 eligible research studies (33,8008 patients) in the current meta-analysis. Among COPD patients, the hazard of all-cause mortality among users of aspirin or clopidogrel was 17% lower (HR: 0.83; 95% CIs (0.70, 0.97; I2 = 73%, X2: 33.34) compared to non-users of anticoagulants (aspirin or clopidogrel). The hazard of dyspnea among users of aspirin or clopidogrel was 3% lower (HR: 0.97; 95% CIs (0.27, 3.49; I2 = 93%, X2: 42.15) compared to non-users of anticoagulants (aspirin or clopidogrel). There was no statistically significant effect of aspirin on other clinical outcomes such as myocardial infarction (HR: 2.04; 95% CIs (0.02, 257.33) and major bleeding (HR: 1.93; 95% CIs (0.07, 1002.33). The funnel plot and Egger's regression test did not show any evidence of publication bias; (4) Conclusions: Overall, we found a positive and beneficial effect of aspirin and/or clopidogrel in reducing all-cause mortality among COPD patients. However, there is uncertainty of evidence for other clinical outcomes such as exacerbation of dyspnea, myocardial infarction, and major bleeding. A limited number of studies examining other clinical outcomes warrant conducting more robust epidemiological studies to assess the efficacy and safety of aspirin and clopidogrel on other clinical outcomes among COPD patients.

Use of High-Flow Nasal Cannulas in Saudi's Neonatal Level III Intensive Care Units: A Nationwide Questionnaire Study.

Objective. To describe heated humidified high-flow nasal cannulas (HHHFNC) utilization in level III neonatal intensive care units (NICUs) in Saudi Arabia. Methods. A prospective cross-sectional study using an electronic web-based questionnaire. The survey targeted level III NICUs hospitals using HHHFNCs, covering HHHFNC availability, protocols, patient characteristics, and indications. It also collected opinions on the benefits of HHHFNCs compared to nasal continuous positive airway pressure (nCPAP). Results. Out of 47 government-level III neonatal intensive care units, 35 (74%) responded to the survey. Among the included units, 46% had guidelines for HHHFNC use. Additionally, 51% reported using HHHFNC in infants of all gestational ages. The primary indication for HHHFNC use was weaning off nCPAP (34%), with 60% of the respondents noting its advantages for kangaroo care and breastfeeding. Conclusion. HHHFNC are increasingly prevalent in NICUs in Saudi Arabia. However, there remain no clear policies or guidelines regarding their use in preterm infants.

Are There Interindividual Responses of Cardiovascular Disease Risk Markers to Acute Exercise? A Replicate Crossover Trial.

PURPOSE: Using a replicated crossover design, we quantified the response heterogeneity of postprandial cardiovascular disease risk marker responses to acute exercise. METHODS: Twenty men (mean (SD) age, 26 (6) yr; body mass index, 23.9 (2.4) kg·m -2 ) completed four 2-d conditions (two control, two exercise) in randomized orders. On days 1 and 2, participants rested and consumed two high-fat meals over 9 h. Participants ran for 60 min (61 (7)% of peak oxygen uptake) on day 1 (6.5 to 7.5 h) of both exercise conditions. Time-averaged total area under the curve (TAUC) for triacylglycerol, glucose, and insulin were calculated from 11 venous blood samples on day 2. Arterial stiffness and blood pressure responses were calculated from measurements at baseline on day 1 and at 2.5 h on day 2. Consistency of individual differences was explored by correlating the two replicates of control-adjusted exercise responses for each outcome. Within-participant covariate-adjusted linear mixed models quantified participant-by-condition interactions and individual response SDs. RESULTS: Acute exercise reduced mean TAUC-triacylglycerol (-0.27 mmol·L -1 ·h; Cohen's d = 0.29, P = 0.017) and TAUC-insulin (-25 pmol·L -1 ·h; Cohen's d = 0.35, P = 0.022) versus control, but led to negligible changes in TAUC-glucose and the vascular outcomes (Cohen's d ≤ 0.36, P ≥ 0.106). Small-to-moderate, but nonsignificant, correlations were observed between the two response replicates ( r = -0.42 to 0.15, P ≥ 0.066). We did not detect any individual response heterogeneity. All participant-by-condition interactions were P ≥ 0.137, and all individual response SDs were small with wide 95% confidence intervals overlapping zero. CONCLUSIONS: Large trial-to-trial within-subject variability inhibited detection of consistent interindividual variability in postprandial metabolic and vascular responses to acute exercise.

The long-term effects of COVID-19 on pulmonary status and quality of life.

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.

E-cigarette use and respiratory symptoms in adults: A systematic review and meta-analysis.

INTRODUCTION: Electronic cigarette (e-cigarette) use is gaining popularity among adults. Monitoring e-cigarette-induced respiratory symptoms is crucial for both clinical and regulatory purposes. We systematically reviewed the current literature to understand the prevalence of respiratory symptoms among exclusive e-cigarette users, dual users, and former smokers. METHODS: Databases searched included PubMed, CINAHL, Cochrane Library, Embase, and Scopus. We included all English-language, empirical quantitative articles that explored the prevalence of e-cigarette-related respiratory symptoms. Random-effects models were utilized in conducting the meta-analyses. The quality of identified studies was evaluated using the NIH Study Quality Assessment Tools. This study is registered with PROSPERO(#CRD42020165973). RESULTS: The literature search identified 1240 references. After removing duplicates and screening for eligibility, 168 studies were included in the final review. The majority of included studies reported a wide range of adverse respiratory symptoms. The respiratory symptoms were prevalent among the exclusive e-cigarette users, dual users, and those who switched from combustible cigarettes to e-cigarettes. Further, out of the RCT studies, 5 were rated as good quality, while 3 were rated as fair. Among the observational studies, 24 were rated as good quality, and 9 were rated as fair. The two experimental studies were both rated as fair quality. CONCLUSIONS: Continued monitoring of respiratory symptoms among e-cigarette users is warranted. Due to the heterogeneity and inconsistencies among studies, which limit result interpretation and highlight the need for studies assessing causal inference, further research using robust study designs is essential. This will provide clinicians with comprehensive knowledge about the potential respiratory risks of e-cigarette use.

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.

The relationship between chronic lung disease diagnosis and the susceptibility to e-cigarette use in adults: The mediation effects of psychosocial, cognitive influences, and the moderation effect of physiological factors.

INTRODUCTION: There is a paucity of studies on e-cigarette use among adults with chronic lung disease. In the present study, we aimed to assess whether psychosocial or cognitive factors elucidate the relationship between chronic lung disease (CLD) and susceptibility to e-cigarette use and whether the relationship between CLD and e-cigarette use is conditional on the presence of respiratory symptoms. METHODS: We recruited adults aged ≥18 years in Alabama with CLD from university medical clinics (n=140) and individuals without CLD (n=123 as a reference group). Information on sociodemographics, susceptibility to e-cigarette use, psychosocial factors, and cognitive factors were collected. Mediation analysis was used to assess whether the psychosocial factors or cognitive factors explained the association between CLD and susceptibility to using e-cigarettes, and moderation analysis was conducted to determine if respiratory factors would change the association between CLD and susceptibility to e-cigarette use. RESULTS: Psychosocial factors (stress, depression, anxiety) and e-cigarette positive expectancy were notably high among individuals with CLD. Having CLD was associated with a lower likelihood of susceptibility to e-cigarette use. Higher levels of stress, being a smoker, boredom, taste/sensorimotor manipulation, and social facilitation were associated with higher odds of susceptibility to using e-cigarettes among individuals with CLD. Mediation analysis indicated a statistically significant indirect effect of CLD on the susceptibility to using e-cigarettes through stress and boredom reduction. We did not find a statistically significant interaction between CLD and respiratory symptoms affecting susceptibility to using e-cigarettes. CONCLUSIONS: Individuals with CLD often exhibit stress, depression, and a positive view of e-cigarettes but are generally less inclined to use them. Stress, smoking habits, boredom, taste, and social influence can increase their susceptibility to e-cigarette use. Our findings call for further exploration to evaluate the temporal relationship between CLD status, psychosocial factors, cognitive factors, and susceptibility to using e-cigarettes. TRIAL REGISTRATION: The study was registered on ClinicalTrials.gov, on 5 November 2019. Identifier: NCT04151784.

Complete Pathological Response to Platinum-Based Neoadjuvant Chemotherapy in BRCA2-Associated Locally Advanced Pancreatic Cancer: A Case Report and Literature Review.

Pancreatic ductal adenocarcinoma (PDAC) is a lethal malignant disease and is considered the fourth leading cause of death among cancer patients in the United States. Mutations in the BRCA gene, which is a DNA repair gene, increase the risk of PDAC, and among all patients with PDAC, about 8%-10% have a BRCA2 mutation. The finding of gene mutations is associated with a better response to platinum-based chemotherapy. Here, we present a case of a 59-year-old male with a BRCA2 gene mutation who was diagnosed with locally advanced pancreatic cancer and had achieved a complete pathological response to the FOLFIRINOX (leucovorin calcium, fluorouracil, irinotecan hydrochloride, and oxaliplatin) regimen and Whipple procedure. We also present our literature findings on response types in BRCA2 PDAC patients, as well as consensus on the use of different therapies. The use of platinum-based chemotherapy with BRCA2 is highly recommended as the first-line treatment. Most PDAC patients remain untested for BRCA2 mutation even though their genetic status influences the selection of drug regimens. Thus, we recommend genetic testing for everyone with PDAC.

The Ability of Emergency Medical Service Staff to Predict Emergency Department Disposition: A Prospective Study.

Purpose: Paramedics' decision to notify receiving hospitals and transport patients to an appropriate healthcare facility is based on the Prediction of Intensive Care Unit (ICU) and Hospital Admissions guide. This study aimed to assess the paramedics' gestalt on both ward and ICU admission. Patients and Methods: A prospective study was conducted at King Abdulaziz Medical City between September 2021 and March 2022. Paramedics were asked several questions related to the prediction of the patient's hospital outcome, including emergency department (ED) discharge or hospital admission (ICU or ward). Additional data, such as the time of the ambulance's arrival and the staff years of experience, were collected. The categorical characteristics are presented by frequency and percentage for each category. Results: This study included 251 paramedics and 251 patients. The average age of the patients was 62 years. Of the patients, 32 (12.7%) were trauma, and 219 (87.3%) were non-trauma patients. Two-thirds of the patients (n=171, 68.1%) were predicted to be admitted to the hospital, and 80 (31.8%) of the EMS staff indicated that the patient do not need a hospital or an ambulance. The sensitivity, specificity, PPV, and NPV of the emergency medical service (EMS) staffs' gestalt for patient admission to the hospital were, respectively (77%), (33%), (16%), and (90%). Further analysis was reported to defend the EMS staffs' gestalt based on the level of EMS staff and the nature of the emergency (medical vs trauma), are reported. Conclusion: Our study reports a low level of accurately predicting patient admission to the hospital, including the ICU. The results of this study have important implications for enhancing the accuracy of EMS staff predictive ability and ensuring that patients receive appropriate care promptly.

Changes in the patterns of respiratory support and incidence of bronchopulmonary dysplasia; a single center experience.

BACKGROUND: With the advances in neonatal intensive care, the survival rate of extremely preterm infants is increasing. However, bronchopulmonary dysplasia (BPD) remains a major cause of morbidity among infants in this group. This study examined the changes in respiratory support modalities, specifically heated humidified high-flow nasal cannula (HHHFNC), and their association with BPD incidence among preterm infants born at < 29 weeks of gestation. METHOD: This population-based retrospective cohort study included infants born at < 29 weeks of gestation between 2016 and 2020. Data regarding the use and duration of respiratory support modalities were obtained, including mechanical ventilation, continuous positive airway pressure, HHHFNC, and low-flow oxygen therapy. Additionally, the incidence of BPD was determined in the included infants. Trend analysis for each respiratory support modality and BPD incidence rate was performed to define the temporal changes associated with changes in BPD rates. In addition, a logistic regression model was developed to identify the association between BPD and severity grade using HHHFNC. RESULTS: Three Hundred and sixteen infants were included in this study. The use and duration of HHHFNC therapy increased during the study period. Throughout the study period, the overall incidence of BPD was 49%, with no significant trends. The BPD rate was significantly higher in the infants who received HHHFNC than in those who did not (52% vs. 39%, P = 0.03). Analysis of BPD severity grades showed that both grade 1 BPD (34% vs. 21%, P = 0.03) and grade 2 BPD (12% vs. 1%, P < 0.01) were significantly more common among infants who received HHHFNC than among those who did not. In contrast, the incidence of grade 3 BPD was lower in infants who received HHFNC (6% vs. 17%, P < 0.01). The duration in days of HHHFNC was found to significantly predict BPD incidence (OR 1.04 [95%CI: 1.01-1.06], P < 0.01) after adjusting for confounding variables. CONCLUSION: The use of HHHFNC in extremely preterm infants born at < 29 weeks of gestation is increasing. There was a significant association between the duration of HHHFNC therapy and the development of BPD in extremely preterm infants born at < 29 weeks of gestation.

Relationship Between Heart Disease and Obesity Indicators Among Adults: A Secondary Data Analysis.

Background Body mass index (BMI), waist circumference (WC), and hip circumference (HC) determine obesity. Several studies have examined the association between obesity and many diseases, including heart disease, and found it to be a substantial risk factor. However, the relationship between heart disease and obesity has not been investigated. This study investigated the relationship between heart disease and obesity indicators among adults encompassing sociodemographic and lifestyle factors. Methodology This cross-sectional study included data from 3,574 individuals who participated in the 2011-2014 National Survey of Midlife Development in the United States refresher. The presence or absence of heart conditions such as irregular heartbeat, heart murmur, heart attack, and heart failure was determined using self-reported questionnaires. The association between heart disease and obesity indicators such as BMI, WC, HC, and waist-to-hip ratio (WHR) was investigated using linear regression. Results After controlling for all factors, the findings demonstrated a significant relationship between heart disease and BMI, WC, and HC high scores of 1.12 kg/m2, 0.63 inches, and 0.81 inches, respectively. A higher score in all obesity indicators was linked to being 65 years or older; male gender (for HC); having a school/college level of education; being unmarried, divorced, or widowed; having a history of smoking; and avoiding alcohol use. Conclusions Heart disease and sociodemographic and lifestyle factors are substantially associated with a high score in all obesity indicators. The findings of this study are important because they can assist healthcare providers in implementing different therapies to prevent high BMI, WC, HC, and WHR.

The associations between cigarette smoking behavior and the use of heated tobacco products among Arab cigarette smokers: Findings from Saudi Arabia, Egypt, Kuwait, and Yemen.

As the availability of tobacco forms has evolved, emerging products known as heated tobacco products (HTPs) are increasingly being consumed worldwide and are claimed to be less harmful than tobacco cigarette smoking. To date, it is unknown whether Arab cigarette smokers are using or susceptible to HTPs. Therefore, this study aimed to assess the association between cigarette smoking behavior and the use of and susceptibility to HTPs in the Eastern Mediterranean region. Arab cigarette smokers (n = 628) from Saudi Arabia, Egypt, Kuwait, and Yemen were recruited using a convenience sampling technique. A cross-sectional survey comprised questions related to sociodemographic characteristics, cigarette smoking behavior characteristics (quitting attempts and desire to quit cigarette smoking, nicotine dependence, and consideration of switching to nicotine products with reduced health risks), and awareness of, use of, and susceptibility to use of HTPs. Descriptive and logistic regression models were used for analysis. The participants indicated a high frequency of past quitting attempts and a desire to quit smoking cigarettes. They were also considering switching to a nicotine product with reduced health risks. However, their awareness of HTPs was relatively low (24.2%), and the proportion of participants who had ever used HTPs or were currently using them was quite low as well (10.7% and 5.0%, respectively). A history of quit attempts was associated with more likely lifetime use of HTPs (adjusted odds ratio [AOR] = 2.63, 95% confidence interval [CI] [1.21-5.71]). Nicotine-dependent cigarette smokers were more likely to be susceptible to HTP use (AOR = 1.12, 95% CI [1.01-1.24]). Moreover, those who would consider switching to a product that provided nicotine and could reduce health risks by 99% were more likely to be susceptible to using HTPs (AOR = 2.17, 95% CI [1.05-4.51]). Awareness of HTPs is relatively low among Arab cigarette smokers. Attempts to quit cigarette smoking, nicotine dependence, and the consideration of switching to a product that delivers nicotine with reduced health risks were significantly associated with using HTPs. The findings of this study provide potential for evidence-based treatment for smokers and will help prevent the use of tobacco industry tactics in marketing HTPs.

Effect of Acute Walking on Endothelial Function and Postprandial Lipemia in South Asians and White Europeans.

INTRODUCTION: South Asians (SAs) have an elevated risk of cardiovascular disease (CVD) compared with White Europeans (WEs). Postprandial endothelial function (flow-mediated dilatation (FMD%)) in SA women and SA men with central obesity has not been investigated. Research in other populations has highlighted that a 1% higher FMD% is associated with a ~13% lower risk of future CVD events. We investigated whether FMD% and lipemia, two markers for CVD risk, were higher in SAs versus WEs, whether walking improved FMD% and lipemia, and if there were ethnic differences in the response. METHODS: Lean premenopausal women (study 1; 12 SA, 12 WE) and men with central obesity (study 2; 15 SA, 15 WE) completed two 2-d trials. On day 1, participants walked for 60 min at 60% of their peak oxygen uptake or rested. On day 2, participants rested and consumed two high-fat meals over 8 h. Repeated ultrasound assessments of endothelial function and venous blood samples for CVD risk markers were taken. RESULTS: Compared with WEs, SAs had lower postprandial FMD% (study 1, -1.32%; study 2, -0.54%) and higher postprandial triacylglycerol concentrations (study 1, 0.31 mmol·L -1 ·h -1 ; study 2, 0.55 mmol·L -1 ·h -1 ). Walking improved postprandial FMD% (study 1, 1.12%; study 2, 0.94%) and resulted in no significant change or small reductions in postprandial triacylglycerol concentrations (study 1, -0.01 mmol·L -1 ·h -1 ; study 2, -0.25 mmol·L -1 ·h -1 ). Exercise-induced changes in FMD% and triacylglycerol were consistent between ethnic groups. CONCLUSIONS: Walking mitigated the adverse postprandial effect of a high-fat diet on FMD% to a similar extent in SA and WE women and men, even with no/small improvements in triacylglycerol. This study highlights the importance of exercise to clinically improve FMD% in SAs and WEs.

The Intersection of Health Rehabilitation Services with Quality of Life in Saudi Arabia: Current Status and Future Needs.

Quality of life (QoL) is essential for maintaining a healthy, balanced lifestyle, especially among individuals with chronic diseases. Saudi Arabia (SA) launched a health sector transformation program as part of the nationwide Vision 2030 initiative to ensure the sustainable development of efficient healthcare services, aiming to improve health by increasing well-being and QoL. More investigation into the current status of health rehabilitation services provided to individuals with chronic diseases and future needs to optimize services and improve QoL is needed. This was narratively discussed by experts from different health rehabilitation services in SA. Comprehensive health rehabilitation services including orthopedic, occupational, cardiac, pulmonary, critical care, perioperative, hearing and speech, substance use disorders, and vocational rehabilitation services were addressed. Health rehabilitation services in SA, as in other countries, are suboptimal for individuals in health rehabilitation programs. To optimize the QoL of individuals with chronic diseases, health rehabilitation services should be tailored based on the unique requirements of each service and its serving patients. The shared need to improve health rehabilitation services includes the adoption of home-based and telehealth services, the integration of multi-governmental sectors, the empowerment and allocation of health rehabilitation specialists, public awareness campaigns, policy legislation and guideline development, and the implementation of a long-term follow-up system. This review is one of the first to address the intersection of health rehabilitation services and QoL in SA; urgent and holistic actions are paramount to address the pressing need to optimize SA's health rehabilitation services. The experts' recommendations in this study may be applicable to other countries' health systems, as health rehabilitation services are not well optimized globally.

Epidemiological associations of asthma status and tobacco use, substance use, and substance misuse among adults in the United States, 2015-2019.

Objective: Adults with asthma have a higher prevalence of substance use. However, knowledge is scarce regarding the associations between adults with asthma and tobacco use, substance use, and substance misuse. This study aimed to use national samples of United States adults to assess the comprehensive use and misuse of substances in adults with asthma.Method: This cross-sectional study comprised data drawn from the 2015 to 2019 National Survey on Drug Use and Health. Weighted logistic regressions were used to measure the associations of asthma status (lifetime and current) with last month's tobacco use; substance use (alcohol, marijuana, cocaine, crack, heroin, hallucinogens, inhalants); and substance misuse (pain relievers, tranquilizers, stimulants, sedatives). All regression models were controlled for sociodemographic characteristics, comorbidity, last-month serious psychological distress, and co-substance use and misuse. Results: Adults with lifetime asthma (Nweighted = 115,600,887) were less likely to use cigarettes, cigars, smokeless tobacco, inhalants, and polyuse of any substance. In contrast, adults with current asthma (Nweighted = 765,096,31) were more likely to use pipe tobacco, cocaine, non-prescribed tranquilizers, and less likely to use polytobacco products. Adults with lifetime asthma were associated with fewer last-month tobacco and inhalant use than those without lifetime asthma. However, adults with current asthma were associated with greater last month's pipe tobacco, cocaine, and non-prescribed tranquilizers. Conclusion: Thus, further longitudinal studies are recommended among adults with asthma to effectively design tailored treatment and prevention interventions.

The associations between the credibility of the tobacco control regulatory body and smoking behavior change among Saudi smokers.

INTRODUCTION: Recently, Saudi Arabia has extensively reformed its tobacco control policies and extended its smoking cessation services. A public outrage on social media among smokers was witnessed, especially after the implementation of plain cigarette packaging, which might have discredited the significant efforts of tobacco treatment services and tobacco control policies. However, it is not known how the credibility of the tobacco control regulatory body among Saudi smokers might affect their smoking behavior. METHODS: Saudi tobacco smokers (n=511) were recruited using a convenience sampling technique. A cross-sectional survey was conducted comprising questions related to the credibility of the tobacco control regulatory body (modified Food and Drug Administration Tobacco Credibility Scale), quit attempts, use of nicotine replacement therapy (NRT), and motivation to change smoking behavior in the future. Logistic and linear regression models were used for the analysis. RESULTS: The public interest subscale of the credibility of the tobacco control regulatory body, was positively associated with confidence in changing smoking behavior (ß=0.204; 95% CI: 0.078-0.713; t=2.449, p=0.015) and readiness to change smoking behavior (ß=0.237; 95% CI: 0.127-0.727; t=2.802, p=0.005). Moreover, the subscale of expertise was positively associated with confidence in changing smoking behavior (ß=0.190; 95% CI: 0.006-0.697; t=1.999, p=0.046) and readiness to change smoking behavior (ß=0.225; 95% CI: 0.063-0.710; t=2.352, p=0.019). However, public interest in the credibility of the tobacco control regulatory body was negatively associated with NRT use among smokers who tried to quit (adjusted odds ratio, AOR=0.691; 95% CI: 0.526-0.909). The credibility of the tobacco control regulatory body, however, was not associated with the last month's or ever quit attempts. CONCLUSIONS: The credibility of the tobacco control regulatory body was positively associated with motivation to change smoking behavior but negatively associated with NRT use. Optimizing communication tools with the public is a potential avenue for improving smoking treatment and prevention in Saudi Arabia.

Burnout Among Respiratory Therapists in a tertiary hospital in Saudi Arabia.

Background: Respiratory therapists (RTs) provide various types of patient care in different clinical settings. Burnout can have an undesirable effect on RTs and their patients. Managing the COVID-19 pandemic, specifically in hospitals, could induce stress in RTs and increase the likelihood of burnout. Therefore, this study aimed to measure the level of burnout among RTs during the COVID-19 pandemic.Method: A validated cross-sectional questionnaire was used to identify the prevalence and characteristics of burnout among RTs. The questionnaire was administered by the respiratory care department of a tertiary healthcare center in Riyadh, Saudi Arabia. The data analysis included descriptive, inferential, and correlational tests.Results: The survey was distributed among 100 RTs with a response rate of 66%. Most respondents reported high burnout levels in the three domains of burnout: 77% reported emotional exhaustion, 98% reported depersonalization, and 73% reported low personal achievement. Univariate analysis revealed that emotional exhaustion was significantly higher among RTs who were male, married, or working in critical care settings. Female RTs and those working in general care settings reported feelings of reduced personal achievement. Furthermore, the analysis revealed a moderate positive correlation between the years of experience and emotional exhaustion (r=0.6, p<0.001).Conclusions: A high prevalence of burnout was observed among RTs in one Saudi tertiary hospital. Burnout is associated with several factors, and interventions should target all domains of burnout. RT management and staff are responsible for addressing their needs and collaboratively working together to overcome burnout. Further investigations focusing on techniques and strategies to alleviate burnout are required.

Effects of Abstinence Self-Efficacy and Outcome Expectancies of Tobacco Smoking on the Desire to Quit Among Saudi Women: A Cross-Sectional Mediation Analysis.

BACKGROUND: Smoking is one of the major preventable causes of morbidity and mortality and has been associated with numerous illnesses. While smoking is increasing among Saudi women, the characteristics of smoking behavior related to abstinence self-efficacy, which is a belief regarding one's ability to successfully resist performing a behavior, and outcome expectancies, meaning the anticipated consequences of performing a behavior, are unknown. Therefore, this study aimed to test whether abstinence self-efficacy mediated the relationship between tobacco smoking outcome expectancies and the desire to quit tobacco among Saudi women who smoke. METHODS: This cross-sectional study collected a sample of 211 Saudi women who smoked tobacco, including cigarettes and shisha. A self-administered questionnaire was used to examine several variables, including abstinence self-efficacy, outcome expectancies, and desire to quit tobacco smoking. Mediational path analysis was used to answer the research question. Indirect effects were estimated through a bootstrapping of 10,000. RESULTS: All 4 constructs of outcome expectancies (negative consequences, positive reinforcement, negative reinforcement, and appetite/weight control) were associated with lower abstinence self-efficacy and desire to quit tobacco smoking. In the mediation analysis, the indirect effect of negative consequences (standardized beta = -.013, SE = .008, 95% CI [-.030, -.001]), negative reinforcement (standardized beta = -.012, SE = .006, 95% CI [-.025, -.001]), and appetite/weight control (standardized beta = -.008, SE = .006, 95% CI [-.022, -.001]) through abstinence self-efficacy were significant, suggesting mediation in the relationship between outcome expectancies and desire to quit tobacco smoking. CONCLUSION: Cognitive mechanisms that may explain the desire to quit tobacco smoking among Saudi women were identified. Although future longitudinal studies are required to determine relationships prospectively, targeted interventions that correct tobacco smoking outcome expectancies and boost abstinence self-efficacy skills may reduce tobacco smoking among Saudi women.
