Survival and Predictors of Mortality of Congenital Diaphragmatic Hernia in Newborns at a Tertiary Care Hospital in Saudi Arabia.

Background Congenital diaphragmatic hernia (CDH) is a condition where abdominal contents protrude into the chest due to defects in the diaphragm muscle. It is considered an emergency that needs urgent intervention to prevent further complications or death. Our study aimed to estimate survival and evaluate predictors of mortality in newborns with CDH using available prediction tools in the literature. Methods This retrospective cohort study included neonates with CDH in King Abdulaziz Medical City (KAMC), Jeddah, from 2000 to 2021. Prevalence, demographics, and clinical characteristics were compared between surviving and deceased infants. C-statistics were used to measure the area under the curve for the prenatal and postnatal predictor tools, and a p-value of <0.05 was considered significant. Results Between 2000 and 2021, 45 neonates with CDH were included (six per 10,000 inborn live births). The mortality rate was 51.1%. The differences in demographics were not significant among surviving and deceased patients. One prenatal predictor tool, the lung-to-head ratio, was found to be significant; in addition, three postnatal predictor tools of mortality, SNAP-II, CDHSG-probability survival, and Brindle Score, had the highest concordance (C) statistics of 0.8, 0.79, and 0.8, respectively. Conclusion Although the incidence of CDH was found to be higher in our study compared to global statistics, our mortality rates correspond with international figures. The most significant differences between predictors and prediction models of mortality were lung-to-head ratio prenatally, SNAP-II, CDHSG-probability survival, and Brindle Score postnatally. Further multicentered studies are recommended with a larger sample size.

Prevalence of abnormal pap smears in the western region of Saudi Arabia from 2010 to 2022.

Objectives: The objectives of the study were to assess the prevalence of abnormal Pap smears and their quality metrics in a tertiary health-care facility in the western region of Saudi Arabia and to share our data with other researchers in Saudi Arabia to potentially establish benchmark data based on a Saudi population. Material and Methods: A retrospective study was carried out by the Department of Pathology at King Fahd Armed Forces Hospital, Jeddah, Saudi Arabia, on Pap smear statistics for 14,376 Pap smears of both conventional and liquid-based cytology (LBC) between 2010 and 2022. Results: The prevalence of abnormal Pap smears of both conventional and LBC was 3.05% (438 Pap smears). The percentages of adenocarcinoma and squamous cell carcinoma were 0.08% and 0.02%, respectively, and the ratio of atypical squamous cells (ASCs) to squamous intraepithelial lesions (SILs) (ASC/SIL) was 2.61. Conclusion: The prevalence of abnormal Pap smears and the ASC/SIL ratio were consistent with the international benchmark data provided by the College of American Pathologists for each preparation type and within the range of the data provided by published studies, highlighting the need for greater focus on glandular abnormalities.

Role of Multidisciplinary Team Meetings in the Diagnosis and Management of Diffuse Parenchymal Lung Diseases in a Tertiary Care Hospital.

Background Decisions on the management of interstitial lung diseases (ILD) and prognostication require an accurate diagnosis. It has been proposed that multidisciplinary team (MDT) meetings for ILD (ILD-MDT) improve these decisions in challenging cases of ILD. However, most studies in this field have been based on the decisions of individual clinicians and there are few reports on the outcomes of the ILD-MDT approach. We therefore describe the experience of the ILD-MDT meetings at our institution. Methods A single-center retrospective review of the electronic health care records of patients discussed in the ILD-MDT meetings at our institution from February 2016 to January 2021 was performed. At out institution, at each ILD-MDT meeting, the referring pulmonologist presents the clinical history and the results of all relevant investigations including serology, blood gas analyses, lung function tests, bronchoscopy, and bronchoalveolar lavage. A radiologist then describes the imaging including serial computed tomography (CT) scans. When available, the findings on lung biopsy are presented by a pathologist. Subsequent discussions lead to a consensus on the diagnosis and further management. Results The study included 121 patients, comprising 71 (57%) males and 76 nonsmokers (62.8%), with a mean age of 65 years (range: 25-93 years). The average number of comorbidities was 2.4 (range: 0-7). Imaging-based diagnoses were usual interstitial pneumonia (UIP)/chronic hypersensitivity pneumonitis (CHP) in 32 (26%) patients, UIP in 20 (17%) patients, probable UIP in 27 (22%) patients, nonspecific interstitial pneumonia in 11 (9%) patients, and indeterminate interstitial lung abnormalities (ILA) in 10 (8%) patients. The most common consensus clinical diagnosis after an ILD-MDT discussion was chronic hypersensitivity pneumonitis/idiopathic pulmonary fibrosis in 17 patients (14%), followed by idiopathic pulmonary fibrosis and connective tissue disease associated interstitial lung disease in 16 patients (13%), CHP in 11 patients (9.1%), and ILA in 10 patients (8.4%). Only a 42 patients (35%) required surgical lung biopsy for confirmation of the diagnosis. Conclusion This study describes the characteristics of the patients discussed in the ILD-MDT meetings with emphasis on their clinical, radiological, and laboratory data to reach a diagnosis and management plan. The decisions on commencement of antifibrotics or immunosuppressive therapy for patients with various ILDs are also made during these ILD-MDT meetings. This descriptive study could help other health care professionals regarding the structure of their ILD-MDT meetings and with discussions about diagnostic and care decisions for diffused parenchymal lung disease patients.

Colorectal cancer-related resource utilization and healthcare costs in Saudi Arabia.

Background: Recently, there has been an increase in the incidence of colorectal cancer in Saudi Arabia. Although numerous studies worldwide have investigated the economic burden of colorectal cancer the information specific to Saudi Arabia remains limited. While advanced cancer treatments offer substantial benefits, they they also come with substantial financial challenges. Objective: This study aimed to estimate the economic burden of colorectal cancer and identify the primary cost drivers. Method: This retrospective, single-center cost of illness study examined all patients with colorectal cancer from January 2017 to December 2020. This study used a micro-costing, bottom-up approach to estimate healthcare resource utilization and direct medical costs associated with colorectal cancer. Result: The study included 326 patients with colorectal cancer. The total direct medical cost for all patients were $19 million, with an annual cost per patient of $58,384. Medication costs were the primary driver of healthcare spending (45%) of the total cost, followed by surgical costs (27%). This study explained cost associated with colorectal cancer, which represents a significant cost to the Saudi healthcare budget. The expected growth and aging of the population and availability of costly treatments may lead to an increase in costs. These findings are valuable for healthcare policymakers seeking to comprehend the economic challenges posed by colorectal cancer.

The most common pulmonary diseases length of stay, and characteristics of patients admitted to pulmonary service.

BACKGROUND: Although chronic respiratory diseases are prevalent in Saudi Arabia, there are limited data on the patient burden and associated factors. The aim of this study is to identify the chronic respiratory diseases frequently admitted to pulmonary services and to determine the patient's characteristics, associated comorbidities readmission rate, and reason for a more extended stay in hospital. METHODS: A prospective study was conducted over a 5-year period at King Abdulaziz Medical City-Riyadh, Saudi Arabia, in the Pulmonary Division, between March 2015 and December 2019. Data on demographics, comorbidities, and chronic respiratory diseases were collected. RESULTS: Total patients admitted were 1315 patients, female 54.2%, the mean age was 62.4 (SD±17.6), and the ages ranged from 14 to 98 years. Overall, chronic obstructive pulmonary disease was the most common respiratory disease requiring admission (17.9%), followed by interstitial lung disease (15.8%), bronchiectasis (11.9%), and obesity hypoventilation syndrome (10.8%). The most common comorbidities were obesity (42.5%), diabetes 49.1%, and hypertension 54.9%. Only 135 (10.3%) were readmitted within 30 days posthospital discharge. Among the patients who were readmitted, 103 (76.3%) were readmitted due to issues related to previous admission diagnosis, noncompliance 75 (55.5%), social reasons, and premature discharges in 51 (37.8%) and 29 (21.5%) of the cases, respectively. The respiratory disease varied significantly by gender, age, obesity status, comorbidities, length of stay (LOS), and admissions. CONCLUSION: Chronic respiratory diseases are prevalent in our population and are mainly influenced by gender, age, obesity status, comorbidities, LOS, and admissions. Policymakers and health professionals need to recognize the burden of chronic respiratory diseases on patients and health systems and implement effective prevention programs.

A survival analysis of idiopathic pulmonary fibrosis in the context of antifibrotic therapy in Saudi Arabia.

BACKGROUND: The prognosis of idiopathic pulmonary fibrosis (IPF) can be predicted by the gender, age, and physiology (GAP) index. However, antifibrotic therapy (i.e., nintedanib and pirfenidone) may improve survival. AIMS: This study aimed to compare the outcomes of antifibrotic-treated IPF with the survival predicted by the GAP index. METHODS: A retrospective cohort study was conducted from March 2014 to January 2020. The electronic health-care records of all IPF patients treated with nintedanib or pirfenidone were reviewed. Besides standard demographic and mortality data, the variables required to calculate the GAP index were also extracted. RESULTS: Eighty-one patients (male 55, 68%; age 71.4 ± 10.2 years) with IPF received antifibrotic therapy (nintedanib 44.4%; pirfenidone 55.6%; mean follow-up 35 ± 16.5 months). Cumulative mortality (whole cohort 3 years 12%; 4 years 26%; 5 years 33%) was significantly less than predicted by the GAP index. CONCLUSIONS: The survival of antifibrotic-treated IPF is better than predicted by the GAP index. Novel systems for prognostication are required. The survival benefit from pirfenidone and nintedanib seem similar overall.

Traumatic spinopelvic dissociation: A case series.

Introduction: Spinopelvic dissociation was described first in 1969. It is an injury characterized by the separation of the lumbar spine, with parts of the sacrum, from the rest of the sacrum and pelvis with the appendicular skeleton through the sacral ala. Spinopelvic dissociation has an incidence of approximately 2.9% of all pelvic disruptions and corresponds with high-energy trauma. The objective of this study was to review and analyze a case series of spinopelvic dissociations that were treated in our institution from May 2016 to December 2020. Methods: This was a retrospective study reviewing medical records of a series of cases with spinopelvic dissociating. A total of nine patients were encountered. Demographic data including gender and age were analyzed with the mechanism of injury, fracture characteristics, and classifications in addition to neurological deficits. Fractures were classified by the AO Spine Sacral Classification System. Moreover, neurological deficits were classified using the Gibbon's classification score. Finally, the Majeed score was utilized for the assessment of the functional outcome after the injury. Results: A total of nine patients with spinopelvic dissociation were encountered, seven males and two females. Seven patients were due to motor vehicle accidents, one patient was due to a suicidal attempt, and one patient was due to seizure. Four patients suffered from neurological deficits. One patient needed an intensive care unit admission. Spinopelvic fixation was done for all patients. One patient had surgical wound infection with wound dehiscence, one had infected instruments with confirmed spine osteomyelitis, and one had a focal neurological deficit. Six patients went on to heal and showed complete neurological improvements. Conclusion: Spinopelvic dissociation injuries represent a variety of injuries that are commonly associated with high-energy trauma. The triangular fixation method has proven to be a stable construct in dealing with such injuries.

Nintedanib and pirfenidone for idiopathic pulmonary fibrosis in King Abdulaziz Medical City, Riyadh: Real-life data.

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic progressive age-related lung disease causing relentless fibrosis of the lung parenchyma. Currently, pirfenidone and nintedanib are the two antifibrotic drugs, approved for the treatment of IPF. Both are shown to slow progression by preserving lung functions from rapid decline compared to a placebo. We are reporting a real-life patient experience using these two antifibrotic medications (AFMs) in our tertiary care hospital. METHODS: A retrospective cohort study was conducted for all IPF cases diagnosed in multidisciplinary meetings between 2015 and 2020 at KAMC, Riyadh (Saudi Arabia). We are reporting patients' demographics, lung function, survival, tolerance, side effects, or death in patients taking AFMs. RESULTS: A total of 81 cases were identified. The majority of patients aged 67 years (68%) were men with a median age of 68 years. Late presentation, severe disease, and definite usual interstitial pneumonia patterns were reported in 60% of our patients. The average number of hospital admissions before starting treatment was 1 (range: 0-3) in the nintedanib group and 1.4 (range: 1.2-5) in the pirfenidone group. There was an increase in the number of hospital admissions in the group started on pirfenidone 1.7 (range: 1.9-8) compared to nintedanib 0.5 (range: 0-3), P = 0.001. The observed mortality outcome in this cohort was 4 (11%) and 12 (27%) for nintedanib and pirfenidone, respectively. The predominant side effects were gastrointestinal symptoms for both the groups 18 (22%). CONCLUSIONS: Pirfenidone and nintedanib are the available approved antifibrotic agents used for many years to treat IPF patients. Real-life data showed better tolerability than reported in the West, good compliance, and a manageable side effect profile in this group of elderly and severe IPF patients.

Increased Glypican-3 immunostaining is associated with longer survival outcomes in colorectal carcinoma.

Glypicans (GPC) are involved in the developmental morphogenesis and regulatory processes of cell signalling. Abnormal expression has been observed in different cancer types. One hundred and thirty-seven colorectal carcinoma (CRC) and 44 nodal metastases were used to create tissue microarrays. Immunohistochemistry was done to detect and evaluate the impact of immunostaining patterns of GPC-3 protein in CRC. GPC-3 immunostaining is increased in CRC and nodal metastasis (p < 0.001) and was not association with clinicopathological parameters. GPC-3 immunostaining was associated with longer disease-free survival (p = 0.021) and overall survival (p = 0.05). For the first time, we show GPC-3 immunostaining association with survival outcomes in CRC. GPC-3 may be used as an independent prognostic factor for survival in CRC.

Prevalence of Insomnia Among Patients with Bronchial Asthma.

BACKGROUND: Insomnia is commonly reported in patients with asthma. However, the prevalence of insomnia and its relationship to asthma control have not been established. OBJECTIVE: To determine the prevalence of insomnia in adults with asthma and to evaluate the association between insomnia and level of asthma control. METHODS: This is a cross-sectional study of 200 patients recruited from pulmonary clinics at a tertiary care center. Adults (age ≥16 years) diagnosed with asthma by the primary treating physician were recruited over a 6-month period from December 2018 to May 2019. Asthma and insomnia severity were assessed using the Asthma Control Test and Insomnia Severity Index (ISI). RESULTS: The mean age of participants was 51±17 years, and 67% were female. Insomnia (ISI score ≥10) was present in 46.5% of the participants. The severity of insomnia was inversely related to the level of asthma control: moderate-to-severe insomnia was more frequent in patients with uncontrolled asthma (43%) than in those with partially controlled asthma (25%) or well-controlled asthma (12%) (P < 0.05 for all comparisons). CONCLUSION: Insomnia is common among patients with asthma, especially those with suboptimal asthma control. Further investigations are required to more fully understand the complex relationship between asthma and insomnia.

Combining RSPH9 founder mutation screening and next-generation sequencing analysis is efficient for primary ciliary dyskinesia diagnosis in Saudi patients.

Primary ciliary dyskinesia (PCD) is a clinically and genetically heterogeneous ciliopathy. Dysfunction of motile respiratory and nodal cilia results in sinopulmonary symptoms associated with laterality defects (LD) found in half of the patients. The molecular basis of the disease is insufficiently investigated in patients originating from the Arabian Peninsula. In a group of 16 unrelated Saudi patients clinically suspected of PCD and among whom only 5 (31%) had LD, we first screened by PCR-RFLP two founder mutations, RSPH9 c.804_806del and CCDC39 c.2190del previously identified in patients from the Arabian Peninsula and Tunisia, respectively. When negative, targeted panel or whole-exome sequencing was performed. Three patients were homozygous for the mutation in RSPH9, which encodes an axonemal protein that is absent from nodal cilia. None of the patients carried the CCDC39 founder mutation frequent in Tunisia. NGS analysis showed that nine patients had homozygous mutations in PCD genes. In total, sequential RFLP and NGS analysis solved 75% (12/16) of cases and identified ten distinct mutations, among which six are novel, in nine different genes. These results, which highlight the genetic heterogeneity of PCD in Saudi Arabia, show that the RSPH9 c.804_806del mutation is a prevalent mutation among Saudi patients, whereas the CCDC39 c.2190del ancestral allele is most likely related to the Berber population. This study shows that RSPH9 founder mutation first-line screening and NGS analysis is efficient for the genetic exploration of PCD in Saudi patients. The RSPH9 founder mutation accounts for the low rate of LD among Saudi patients.

The diagnostic yield and safety of sputum induction in suspected pulmonary tuberculosis: The experience of a single tertiary care center in Saudi Arabia.

Background: Sputum smear microscopy examination and culture for tuberculosis (TB) remain a fundamental tool of diagnosis but may be negative up to 50% case of active pulmonary TB. Bronchoscopy to obtain sputum is invasive and not readily available. Alternative methods of obtaining sputum specimens are crucial in suspected pulmonary TB cases who are unable to expectorate. In this context, it may be beneficial to stimulate sputum production by administering a mist of hypertonic saline produced by ultrasonic nebulization. The aims of the study are to describe the experience of a tertiary center in Saudi Arabia with sputum induction (SI) for the investigation of patients suspected to have sputum scare TB. Methods: A retrospective cohort study was performed. All patients suspected of sputum scare TB and investigated with SI were included. Standard descriptive statistics were used. Categorical data presented as frequency were compared using the Chi square test. Continuous data presented as mean ± standard deviation were compared using Student's t test. Sensitivity, specificity, and predictive values were calculated. Results: Of 252 patients with suspected TB who underwent SI, 78 (31%) were ultimately diagnosed to have TB. Culture of induced sputum confirmed the diagnosis of TB in 44 (56.4%) of these patients. However, the diagnosis of TB would have been missed in 13.5% of the cohort if no further investigations were done. The incidence of complications was low. No patients required hospitalization or specialist intervention. Conclusions: SI is safe well tolerated and inexpensive. It may reduce the need for bronchoscopy in patients with suspected sputum scare TB. However, around 20% of TB can be missed by SI unless further investigations are performed. Hence, patients suspected to have sputum scare TB in whom the risk of bronchoscopy is high, a clinical decision on the appropriateness of empirical therapy is often required.

Do ward rounds offer effective teaching and training? Obstacles to learning and what makes good teaching in a large tertiary care hospital from trainee doctor's perspective.

Background: Ward rounds (WR) have been integral to the process of teaching and learning medicine and also provides a vital opportunity to communicate with the patient, their relatives, and other healthcare professionals. Yet in recent years trainees' perception of the educational value of WRs seems to have declined. Objectives: The aim of this study to assess trainees' perception of the educational value of WRs at King Abdulaziz Medical City(KAMC), Riyadh, a 1500 bed academic hospital in Saudi Arabia. Methods: A self-administered, paper-based survey was distributed to physicians in training at KAMC between October and December 2019. All residents who attended WRs were invited to participate. The questionnaire was adapted from a survey used in a previous study. The demographic section requested details of the respondent's age, gender, specialty, and seniority. The second and third sections asked about the logistics of current ward round practices. It included several questions on the structure as well as the duration and frequency of ward rounds. The fourth and fifth sections asked for participant's perception of the opportunities for, and the obstacles to, learning on ward rounds. The subsequent sections asked several questions onward round structure and the clinical teacher. Responses were requested on a 5-point Likert-type scale (strongly disagree, disagree, neutral, agree, strongly agree). The last section asked the participant for general comments and feedback Result: The study targeted 250 residents in specialties that routinely performed WRs. Only 166 residents returned the questionnaire (response rate of 66.4%). Male 89 (53.6%), medical 108 (65.1%), surgical 58 (34.9%), resident in first year 81 (48.8%). The overall average time spent on WR was 13 (± 11 SD) hours per week. The WR was perceived as a good opportunity to learn about diagnostic investigation 138 (83%) and patient management 133(80.1%), history taking114 (68.7%) physical examination 103 (62.0%), and time management skills 86 (51.8%). The majority of our trainees felt that the WR was educationally very useful to 86 (52%) and attribute to at least a third of the education they receive during their training. They also reported that about the quarter of the time spent on WRs is devoted to teaching. The good teacher described as enthusiastic to teach 137 (82.5%), provide feedback to trainees 135 (81%), do not rush 139(83.7), communicate to trainee 144 (86.7), and consultant level,101 (60.8). Trainees also identify a few factors that hinder their training such as lack of time 130 (79%), and the number of patients 129 (78.3). Conclusion: This study identifies the strengths and weaknesses of WR in our institution. Finding will help training supervisors in addressing and rectifying these shortcoming and factors hinder training.

Severe Asthma Patients Experience and Satisfaction with Virtual Clinics during COVID-19 Period.

Background Enforced social distancing (i.e., lockdowns) greatly facilitated control of coronavirus disease-19 (COVID-19). While access to hospitals was restricted, outpatient care continued remotely. The aim of this study was to determine the satisfaction of patients with severe asthma with telemedicine, and the impact of COVID-19 lockdown on severe asthma patients on biologics therapy. Methods A cross-sectional survey of patients with severe asthma scheduled to receive biologic therapy at our hospital during the lockdown. The survey had sections about demographic data, asthma history, subjective perception of change in asthma control with biologic agent, the effect of COVID-19 pandemic on access to maintenance therapy for asthma, asthma exacerbation management, and satisfaction with telephone follow-up. Results Fifty-four patients participated (response rate 93.1%; male 17; mean age 46.7 years). All had been on biologic therapy for over 3 months (mean 38.4 months ± standard deviation 26.5 months). Of the 45 patients living in Riyadh, 9 did not receive biologic therapy. Five of the nine patients living outside Riyadh did not receive biologic therapy. Alarmingly, 16 (29.6%) had insufficient medications, and 27 (50%) had difficulty obtaining medications. Fifty (92.6%) had telephone follow-up, 31 (57.4%) were satisfied with telemedicine. Conclusion Many patients were satisfied with telemedicine, so this could be used to deliver routine outpatient tertiary care postpandemic. However, logistics around supplying medications and biologics must be considered in plans preparing for the second wave of COVID-19.

Prognostic utility of various multidimensional grading scales among Saudi patients with bronchiectasis.

INTRODUCTION: A number of multidimensional scoring systems, including the Bronchiectasis Severity Index (BSI), the FACED score, and the Exacerbation-FACED (Exa-FACED, a derivative of FACED), have been proposed and validated to assess the severity and prognosis in patients with bronchiectasis. Although these metrics have been validated through large multicenter efforts in Europe and Latin America, there have been no attempts at external validation in other populations. OJECTIVES: The aim of this study was to validate specific multidimensional grading scales (BSI, FACED, and Exa-FACED) in predicting mortality, future exacerbations, and hospitalizations among Saudi patients with bronchiectasis. METHODS: A prospective observational cohort study was conducted at a tertiary care centre. The three multidimensional grading scales (BSI, FACED, and Exa-FACED) were calculated for each patient. Future frequent acute exacerbations (≥2/year) and severe acute exacerbations leading to hospitalization were recorded for 1 year, and all-cause mortality was monitored for up to 5 years. RESULTS: A total of 301 patients with bronchiectasis (mean age of 60±17 years and 66% female) were include. All Grading scales performed well in predicting 5-year survival. Area under the curve (AUC) values for BSI (0.86, 95% CI: 0.82-0.90), FACED (0.81, 95% CI: 0.76-0.85), and Ex-FACED (0.83, 95% CI: 0.78-0.87). The BSI (AUC=0.98, 95% CI: 0.96-0.99) performed better than FACED scoring (AUC=0.77, 95% CI: 0.71-0.81; P<0.0001) in predicting hospitalization. Exa-FACED scoring (AUC=0.84, 95% CI: 0.80-0.88) improved upon FACED scores in predicting hospitalization. The BSI (AUC=0.95, 95% CI: 0.91-0.97) fared significantly better than FACED scoring (AUC=0.76, 95% CI: 0.70-0.80; p<0.0001) in predicting frequent acute exacerbations (≥2/year). Again, Exa-FACED scoring (AUC=0.85, 95% CI: 0.81-0.89) improved upon FACED scores in predicting frequent acute exacerbations (≥2/year). CONCLUSIONS: All scoring systems performed adequately in 5-year mortality projections. Although Exa-FACED scoring improved upon FACED scores in predicting forthcoming frequent acute exacerbations and hospitalization, the BSI outperformed both in this regard.

The prevalence of sleep disturbance among asthmatic patients in a tertiary care center.

Sleep disturbances are commonly reported by patients with asthma. However, the prevalence of sleep disturbance and its association with the level of asthma control is unknown. The primary objective was to determine the prevalence of sleep disturbance among Saudi adult asthmatic patients attending pulmonary clinics at King Abdulaziz Medical City (KAMC). The study also aimed to compare sleep quality between controlled and uncontrolled asthma patients. The study was carried out in the outpatient pulmonary clinics at KAMC and utilized a cross-sectional survey. The survey included five different questionnaires: asthma control test and questionnaires related to the quality of sleep (Pittsburgh sleep quality index [PSQI], Epworth sleepiness scale [ESS], Berlin questionnaire [a measure of obstructive sleep apnea risk], and insomnia severity index [ISI]). Among the 200 asthma patients, 66% suffered from poor sleep quality (PSQI > 5), 43% were at high risk for obstructive sleep apnea, 25% had excessive daytime sleepiness (ESS > 10), and 46.5% had significant clinical insomnia (ISI ≥ 10). Poor sleep quality was less common in patients with well-controlled asthma (37%) compared to those with partially controlled asthma (78%) and uncontrolled asthma (82%) (p < 0.001). Poor sleep quality was common among patients with asthma, particularly those with suboptimal levels of asthma control. Further studies are needed to better understand the interaction between these two conditions.

Natural immunity to influenza A and B among Saudi blood donors in Al Madinah Al Munawarah, Saudi Arabia.

OBJECTIVES:  To investigate the seroprevalence of influenza viruses (A and B) among blood donors in Kingdom of Saudi Arabia. Methods: The present investigation was conducted between April 2019 and July 2019. Participants were healthy adults recruited from the central blood bank Al Madinah Al Munawarah, Kingdom of Saudi Arabia. Immunoglobulin G (IgG) levels against influenza A and B were measured in serum samples using ELISA. RESULTS: The results showed that 29.2% of the sample had significant concentrations of influenza A IgG antibody, whereas 38.6% had significant concentrations of influenza B IgG antibody. A strong correlation was found between the levels of influenza A and influenza B antibodies (r=0.708, p less than 0.001). The number of individuals identified as negative for influenza A IgG antibody increased with age (p less than 0.01). In addition, no correlations were identified between influenza A IgG and influenza B IgG and body mass index (BMI), (p greater than 0.05). Finally, linear regression analysis showed that the level of influenza A antibody can be predicted by age (p less than 0.05) and body mass index (BMI) (p less than 0.05). CONCLUSION:  Approximately one-third of Saudi Arabian adults presented significant levels of influenza A and B antibodies in our study. Demographic factors, including age and BMI, might contribute to influenza A antibody levels.

Performance of Multidimensional Severity Scoring Systems in Patients with Post-Tuberculosis Bronchiectasis.

Objective: The aim of this study was to assess the clinical characteristics and outcomes of patients with post-tuberculosis (post-TB) bronchiectasis. We also evaluated the performance of various multidimensional severity score systems to predict mortality, future exacerbation, and hospitalization. Methods: We conducted a prospective observational cohort study to evaluate the etiology of bronchiectasis in 301 patients. Patients fell into three groups: post-TB (129 [43%]), idiopathic (76 [25%]), and other (96 [32%]) etiologies of bronchiectasis. Four multidimensional grading scales, including the Bronchiectasis Severity Index (BSI), the FACED score, and two derivative versions of the FACED score, Exacerbation (Exa-FACED and E-FACED), were calculated and compared for each patient. Results: Patients with post-TB bronchiectasis were predominantly female (61%) with a mean age of 68±11 years. Moreover, 26% of post-TB bronchiectasis patients were colonized with Pseudomonas aeruginosa. At baseline, patients with post-TB bronchiectasis were older, had higher severity scores, and were more likely to have experienced severe exacerbations that required hospitalization compared to patients with idiopathic bronchiectasis or bronchiectasis arising from other causes. During follow-up, 52% of patients required hospitalization, 58% had frequent (≥2 per year) acute exacerbations, and the overall 5-year mortality rate was 30%. Five-year survival was efficiently predicted by each of the grading scales. Although the modified variations of the FACED outperformed the original FACED scale in predicting forthcoming frequent acute exacerbations and hospitalization, the BSI outperformed all three systems in this regard. Conclusion: Patients with post-TB bronchiectasis had higher severity scores than patients with idiopathic bronchiectasis or bronchiectasis arising from other causes. In addition, all scoring systems performed adequately in 5-year mortality projections. BSI and the modified versions of the FACED outperformed the FACED in predicting forthcoming exacerbations and hospitalizations.

Symptoms of Daytime Sleepiness and Sleep Apnea among Pregnant Women.

OBJECTIVES: Despite the fact that sleep disturbances have been associated with poor maternal and neonatal health outcomes in pregnancy, no studies have assessed excessive daytime sleepiness or the risk for sleep apnea among pregnant Saudi Arabian women. We sought to estimate the prevalence of excessive daytime sleepiness (EDS) and the high risk for sleep apnea (OSA) in a sample of pregnant Saudi women. METHODS: An anonymous self-report questionnaire was completed by 517 pregnant women who attended obstetric outpatient clinics at King Abdulaziz Medical City, Riyadh, Saudi Arabia, for a routine pregnancy check. We collected demographic and clinical data for all patients and used the Berlin Questionnaire and the Epworth Sleepiness Scale to determine the primary outcomes. RESULTS: A high risk of OSA was found in 37.1% of women (95% confidence interval (CI): 33.00%-41.50%), and EDS was found in 32.1% (95% CI: 28.10%-36.30%). The presence of both (EDS and a high risk of OSA) was found in 14.9% of women (95% CI: 11.90%-18.30%). We found increased odds of EDS in women who reported pain three times or more per week (adjusted odds ratio (aOR) = 2.59) and insomnia (aOR = 1.65). Older women (≥ 37 years) (aOR = 3.00), those who reported pain once a week (aOR = 1.99), pain twice a week (aOR = 2.75), three times or more a week (aOR = 2.57), and insomnia (aOR = 1.95) increased the odds of high risk for OSA. CONCLUSIONS: EDS and a high risk for OSA affected a large portion of the pregnant women included in the study, primarily those who reported pain and insomnia. Our study provides important information for gynecologists to help promote healthy sleep and manage the issues arising from sleep disturbances among pregnant women as part of their daily practice.

The prevalence of restless leg syndrome among pregnant Saudi women.

OBJECTIVES: Restless legs syndrome (RLS) is common among pregnant women, but it has not been documented in pregnant Saudi Arabian women. The main purpose of this study was to estimate the extent of the prevalence of RLS and identify both the associated factors and the associated risk factors among pregnant Saudi women. METHODS: A cross-sectional study was conducted among pregnant women visiting obstetric clinics at King Abdulaziz Medical City in Riyadh (KAMC-Riyadh) over the period from June 1 to November 1, 2014. We interviewed the participants and collected demographic data, number of pregnancies, duration of pregnancy, comorbidities, and symptoms of RLS. The diagnosis of RLS is based on the four criteria designated by the International RLS Study Group. RESULTS: The total number of participants enrolled was 517, and the mean age was 30.11 ± 5.42 years. The prevalence of RLS was 21.3% (110/517) (95% confidence interval [CI]: 17.83%-25.06%). RLS symptoms were more common among women in the third trimester (24.1%) compared to the second trimester (14.3%) and first trimester (13.6%), P = 0.043. The stepwise multivariate logistic model identified insomnia (odds ratio [OR]: 3.6, 95% CI: 2.167-6.017, P = 0.001), and poor sleep quality (OR: 4.9, 95% CI: 1.473-16.454, P = 0.010) were associated with RLS. CONCLUSION: RLS occurs in two of ten pregnant women visiting obstetric clinics at KAMC-Riyadh and is strongly associated with insomnia and poor sleep quality. Studies are needed to explore the causality of these associations.
