RESUMO
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.
RESUMO
Background: Tuberculosis (TB) is the primary infectious cause of mortality worldwide. Although TB incidence and prevalence are declining, the use of immunosuppressive drugs and the growing prevalence of immunocompromising conditions such as comorbidities, malignancies, and the use of immunosuppressive agents are risk factors for disseminated TB (DTB). This study aims to identify the relevant clinical, laboratory, radiological, and histopathological features of DTB, as well as to assess the typical anatomical distributions and treatment outcomes of patients diagnosed with the disease at King Abdulaziz Medical City (KAMC). Methods: A retrospective chart review was conducted, including all patients diagnosed with miliary or DTB at KAMC with retrievable medical files. Results: The study included 55 patients, of whom 35 (63.6%) were male and the median age was 64 years old. 35 (63.6%) of the infected patients were timely diagnosed and eventually cured from the illness. The most common comorbid conditions were diabetes, chronic kidney disease, and immunocompromising conditions, which were present in 37 (67.2%), 12 (21.8%), and 11 (20%) of the patients, respectively. The most common presenting symptoms were fever and cough, present in 31 (56.3%) and 26 (47.2%) of the patients, respectively, followed by weight loss in 25 (45.4%), night sweats in 15 (27.2%), and shortness of breath in 14 (25.4%). Approximately two-thirds of the patients had pulmonary miliary TB (MTB) (38; 69.1%), followed by TB lymphadenitis (21; 38.2%), central nervous system involvement (13; 23.6%), skeletal involvement (11; 20%), gastrointestinal involvement (5; 9.1%), pleural involvement (3; 5.5%), and urogenital TB (2; 3.6%). The mortality rate was 14 (25.5%) patients. Conclusion: MTB is challenging to diagnose due to nonspecific clinical, laboratory, and imaging findings. Clinicians dealing with patients who are at risk of developing DTB should be aware of the typical presentations and abnormal clinical findings. They should also have a low threshold to initiate specific investigations for the disease, as early diagnosis and effective treatment is critical in reducing morbidity and mortality rates.

PURPOSE: Estimating the prevalence and severity of asthma symptoms with standardized methods of population-based surveys is a critical step in reducing asthma burden. However, no sufficient surveys have been conducted in most countries of the Middle East especially at the national level. In this survey, we applied sound measures to estimate the prevalence and severity of asthma symptoms and related risk factors in adults in Saudi Arabia. PATIENTS AND METHODS: In this national cross-sectional study, the prevalence and severity of asthma symptoms were estimated throughout the country. Overall, 7955 adult individuals were selected from 20 regions across Saudi Arabia through their children at schools using a multistage, stratified cluster-sampling technique. A validated questionnaire, including the core and environmental questions of the Global Asthma Network questionnaires, was applied from March 4 to April 25, 2019. In addition, multivariate logistic regression analysis was performed to investigate the independent relationships between current wheeze and related risk factors. RESULTS: The overall prevalence of current wheeze (wheeze during the past 12 months) was 14.2%. Among persons with current wheeze, 38.1% were affected by severe asthma symptoms. Although a high percentage of those who had experienced asthma-ever reported that their asthma was diagnosed by doctors (83.3%), only 38.4% had a written plan for controlling their asthma. Women were more likely to develop current wheeze (adjusted odds ratio (aOR) 1.4; 95% CI: 1.1-1.7), while other statistically significant factors associated with current wheeze were jobs (aOR 11.8; 95% CI: 7.3-18.9), current exposure to moisture or damp spots (aOR 2.2; 95% CI: 1.5-3.4), heating the house when it is cold (aOR 1.7; 95% CI: 1.3-2.1), and ever using tobacco daily (aOR 2.7; 95% CI: 2.0-3.5). CONCLUSIONS: These findings provide enough evidence for health authorities in Saudi Arabia about the prevalence and severity of asthma symptoms, asthma control, and associated risk factors to scale up monitoring projects, control plans, and high-impact interventions.
RESUMO
Bronchiectasis refers to both a clinical disease and a radiological appearance that has multiple causes and can be associated with a range of conditions. Disease heterogeneity and the absence of standardised definitions have hampered clinical trials of treatments for bronchiectasis and are important challenges in clinical practice. In view of the need for new therapies for non-cystic fibrosis bronchiectasis to reduce the disease burden, we established an international taskforce of experts to develop recommendations and definitions for clinically significant bronchiectasis in adults to facilitate the standardisation of terminology for clinical trials. Systematic reviews were used to inform discussions, and Delphi processes were used to achieve expert consensus. We prioritised criteria for the radiological diagnosis of bronchiectasis and suggest recommendations on the use and central reading of chest CT scans to confirm the presence of bronchiectasis for clinical trials. Furthermore, we developed a set of consensus statements concerning the definitions of clinical bronchiectasis and its specific signs and symptoms, as well as definitions for chronic bacterial infection and sustained culture conversion. The diagnosis of clinically significant bronchiectasis requires both clinical and radiological criteria, and these expert recommendations and proposals should help to optimise patient recruitment into clinical trials and allow reliable comparisons of treatment effects among different interventions for bronchiectasis. Our consensus proposals should also provide a framework for future research to further refine definitions and establish definitive guidance on the diagnosis of 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.

BACKGROUND: The safety and efficacy of rifampin among people living with human immunodeficiency virus (PLHIV) or other health conditions is uncertain. We assessed completion, safety, and efficacy of 4 months of rifampin vs 9 months of isoniazid among PLHIV or other health conditions. METHODS: We conducted post hoc analysis of 2 randomized trials that included 6859 adult participants with Mycobacterium tuberculosis infection. Participants were randomized 1:1 to 10 mg/kg/d rifampin or 5 mg/kg/d isoniazid. We report completion, drug-related adverse events (AE), and active tuberculosis incidence among people living with HIV; with renal failure or receiving immunosuppressants; using drugs or with hepatitis; with diabetes mellitus; consuming >1 alcoholic drink per week or current/former smokers; and with no health condition. RESULTS: Overall, 270 (3.9%) people were living with HIV (135 receiving antiretroviral therapy), 2012 (29.3%) had another health condition, and 4577 (66.8%) had no condition. Rifampin was more often or similarly completed to isoniazid in all populations. AEs were less common with rifampin than isoniazid among PLHIV (risk difference, -2.1%; 95% confidence interval [CI], -5.9 to 1.6). This was consistent for others except people with renal failure or on immunosuppressants (2.1%; 95% CI, -7.2 to 11.3). Tuberculosis incidence was similar among people receiving rifampin or isoniazid. Among participants receiving rifampin living with HIV, incidence was comparable to those with no health condition (rate difference, 4.1 per 1000 person-years; 95% CI, -6.4 to 14.7). CONCLUSIONS: Rifampin appears to be safe and as effective as isoniazid across many populations with health conditions, including HIV. CLINICAL TRIALS REGISTRATION: NCT00170209; NCT00931736.

BACKGROUND: A Do Not Resuscitate (DNR) order should only impede the performance of cardiopulmonary resuscitation in case of cardiac or respiratory arrest; it should not interfere with any other treatment decisions. AIMS: To study the impact of DNR order placement on daily clinical care of patients. METHODS: This was a retrospective cohort study of 72 patients in a tertiary care centre in Saudi Arabia. Daily clinical care measures were collected for 2 weeks prior and 2 weeks after DNR order placement and included vital signs, nursing care, comfort measures, documentation, visits by senior and junior physicians, and tests completed. RESULTS: Malignancy was the most common diagnostic category (43.1%). There was a significant reduction in vital signs documentation, tests completed, documentation, and visits by physicians after DNR orders, with no change in nursing care and comfort measures. No differences were seen for place of DNR order (intensive care unit vs medical ward), category of disease, or sex, but there were differences for documentation (more in females) and vital signs (more in males). More vital signs were documented and more tests were done in patients who survived compared to those who died. Regression analysis showed that the frequency of post-DNR order vital signs measurements and investigations done was not related to sex, age, diagnosis, time from admission to DNR order, or location of patients. Time to death was only related to sex and post-DNR order summary documentation. CONCLUSIONS: Placement of DNR orders significantly reduced vital signs measurements, investigations done, documentation and visits by physicians but not nursing care and comfort measures.

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.

BACKGROUND: Advance directives towards end of life decisions are seldom used among Arabs. AIMS: This study aimed at investigating advance care preferences among a sample of Arab patients. METHOD: This cross-sectional study was undertaken over the period March 2012-March 2013 on a sample of 300 patients with chronic illness in King Fahad National Guard Hospital, Riyadh, a major tertiary care hospital in Saudi Arabia. RESULTS: Mean age of patients in the study was 48.7 years (standard deviation 16.4). There were 104 patients on haemodialysis, 73 with advanced malignancy, 81 with chronic liver disease and 35 with chronic respiratory disease. More than 80% of the respondents felt that the physician should make the decision about cardiopulmonary resuscitation. Over 60% wished to remain at home when their condition deteriorated to impending death. There were no significant correlations between the patients' end of life decision preferences and religiosity, quality of life, disease duration, or other demographic characteristics. CONCLUSION: Despite a significant lack of knowledge among our participants regarding resuscitation, a majority of patients with chronic illness were willing to discuss the options and were capable of making advance directive plans regarding their health status.

BACKGROUND: Tuberculosis (TB) continues to be a public health challenge in Saudi Arabia, particularly for the elderly. This study was conducted to estimate mortality per 1000 person-year among TB and resistant TB cases and to identifying factors associated with mortality. METHODS: This is a retrospective cohort study of 713 new TB cases at King Abdulaziz Medical City in Riyadh diagnosed between January 1, 2000, and December 31, 2016. Patient medical records and microbiology lab databases were used to identify TB cases. Through reviews were conducted of patients' medical records, including physician notes, physical examinations, radiology (scans and imaging), laboratory tests, and follow-up notes. Collected data include demographic information, clinical features, diagnoses, comorbidities, and death rates. RESULTS: Of the 713 TB patients included in this study, 110 died, giving an average mortality rate of 22 per 1000 person-years (PY; 95% CI: 18.2-26.4). Elderly patients (≥ 60 years) had a higher mortality rate of 36.5 per 1000 PY (95% CI: 28.9-45.5). As age increases by one year, the hazard of mortality increase by 2.4% (aHR: 1.024 [95% CI: 1.009-1.039, P = 0.002]). Higher hazard of mortality was found among males (aHR: 2.014 [95% CI: 1.186-3.418, P = 0.010]). Patients with respiratory and other types of comorbidities and cancer had a higher mortality hazard (aHR: 1.898 [95% CI: 1.005-3.582, P = 0.048]; aHR: 2.346 [95% CI: 1.313-4.192, P = 0.004]; aHR: 3.292 [95% CI: 1.804-6.006, P = 0.001]), respectively. Multidrug-resistant TB (MDR-TB) was found in 2 cases (0.28%) (95% CI: 0.08-1.02), 1.68% were resistant to only one antibiotic, 0.14% had rifampicine-resistant TB (RR-TB), 0.28% had MDR-TB, and 0.14% had extensively drug-resistant TB (XDR-TB). CONCLUSIONS: The mortality rate among TB patients was found to be 22 per 1000 person-year at our center. TB was associated with high mortality rates among males, the elderly, and patients with cancer, respiratory illness, and other comorbidities. Future clinical practice should include establishing an efficient TB diagnostic program and continued hazard assessment of TB treatment options.

BACKGROUND: Despite the continuing increase in the breast cancer incidence rate among Saudi Arabian women, no breast cancer risk-prediction model is available in this population. The aim of this research was to develop a risk-assessment tool to distinguish between high risk and low risk of breast cancer in a sample of Saudi women who were screened for breast cancer. METHODS: A retrospective chart review was conducted on symptomatic women who underwent breast mass biopsies between September 8, 2015 and November 8, 2017 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. RESULTS: A total of 404 (63.8%) malignant breast biopsies and 229 (36.2%) benign breast biopsies were analyzed. Women ≥40 years old (aOR: 6.202, CI 3.497-11.001, P=0.001), hormone-replacement therapy (aOR 24.365, 95% CI 8.606-68.987, P=0.001), postmenopausal (aOR 3.058, 95% CI 1.861-5.024, P=0.001), and with a family history of breast cancer (aOR 2.307, 95% CI 1.142-4.658, P=0.020) were independently associated with an increased risk of breast cancer. This model showed an acceptable fit and had area under the receiver-operating characteristic curve of 0.877 (95% CI 0.851-0.903), with optimism-corrected area under the curve of 0.865. CONCLUSION: The prediction model developed in this study has a high ability in predicting increased breast cancer risk in our facility. Combining information on age, use of hormone therapy, postmenopausal status, and family history of breast cancer improved the degree of discriminatory accuracy of breast cancer prediction. Our risk model may assist in initiating population-screening programs and prompt clinical decision making to manage cases and prevent unfavorable outcomes.
RESUMO
BACKGROUND: Imaging tests used in our center are usually inadequate to confirm the high risk for pancreatic cancer. We aimed to use a combination of potential predictors including imaging tests to quantify the risk of pancreatic cancer and evaluate its utility. METHODS: This was a retrospective cohort study of patients who were suspected as having pancreatic cancer and underwent biopsy examination of pancreatic mass at King Abdulaziz Medical City, Riyadh, Saudi Arabia, between January 1, 2013, and December 31, 2016. We retrieved data on demographics, clinical history, imaging tests, and final pancreatic diagnosis from medical records. RESULTS: Of the 206 who underwent pancreatic biopsies, the mean age was 63.6 years; 54.4% were male. Of all the biopsies, 57.8% were malignant and 42.2% were benign masses. Nine factors contributed significantly to the risk of pancreatic cancer and were noted: older age (adjusted odds ratio [aOR] =1.048; P=0.010), male gender (aOR =4.670; P=0.008), weight loss (aOR =14.810; P=0.001), abdominal pain (aOR =7.053; P=0.0.001), blood clots (aOR =20.787; P=0.014), pancreatitis (aOR =4.473; P=0.021), jaundice (aOR =7.446; P=0.003), persistent fatigue (aOR =22.015; P=0.015), and abnormal imaging tests (aOR =67.124; P=0.001). The model yielded powerful calibration (P=0.953), excellent predictive utility (area under the receiver operating characteristic curve 96.3%; 95% CI =94.1, 98.6), with optimism-corrected area under the curve bootstrap resampling of 94.9%. An optimal cut-off risk probability of 0.513 yielded a sensitivity of 94% and specificity of 84.7% for risk classification. CONCLUSION: The study developed and validated a risk model for quantifying the risk of pancreatic cancer. Nine characteristics were associated with increased risk of pancreatic cancer. This risk assessment model is feasible and highly sensitive and could be useful to improve screening performance and the decision-making process in clinical settings in Saudi Arabia.
RESUMO
BACKGROUND: Although psychological symptoms and oral health status are associated with health management and outcomes among cancer patients, their association has not been assessed in Saudi Arabia. We aimed to assess the symptoms of depression, anxiety, and stress and their association with their oral health status, adjusting for sociodemographic and clinical factors. METHODS: A self-reported study included 375 adult cancer patients who received outpatient healthcare services in the Oncology Department, King Abdulaziz Medical City-Riyadh, Saudi Arabia, between April 1 and August 31, 2017. We used the Arabic version of the Depression Anxiety Stress Scale to dichotomize a binary outcome for each. Oral health was evaluated by self-rating from "very good" to "bad". RESULTS: A high prevalence of subjective depression, anxiety, and stress was found (44.8%, 52.5%, and 42.7%, respectively). Of the sample, 17.9% self-reported "bad" oral health, which is associated with a high risk of anxiety and stress, and its association remains significant after controlling for other factors (adjusted odds ratio=6.48 and 4.73, respectively). Being <60 years old, high level of formal education, low income, breast cancer, and lung cancer were associated with increased psychological symptoms. CONCLUSION: Every 6 in 10 cancer patients in this study reported at least one psychosocial symptom. The findings suggest that there exists an association between self-reported "bad" oral health and psychosocial symptoms. Being <60 years old, low income, high level of formal education, breast cancer, and lung cancer were associated with psychological symptoms. Routine psychological counseling and oral health screening in outpatient oncology clinics may improve psychological outcomes and cancer management.
RESUMO
BACKGROUND: Although the frequency of surgical weight loss interventions has increased in Saudi Arabia, literature describing the clinical outcomes of bariatric surgery in Saudi Arabia is limited. This study aimed to assess whether weight loss intervention improves hemoglobin A1c (HbA1c) in obese patients and to identify its associated factors. PATIENTS AND METHODS: A retrospective study was carried out on 318 patients with obesity class 1 or higher (body mass index [BMI] ≥ 30 kg/m2) who underwent laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass at King Abdulaziz Medical City in Riyadh, Saudi Arabia, between January 1, 2001 and March 31, 2017. Preoperatively and 12 months postoperatively, characteristics of patients were collected. BMI reduction was calculated, based on which patients were divided into three groups (0-9, 10-14, and >14 kg/m2). RESULTS: The postoperative HbA1c was 5.83±0.9, while the baseline level was 6.74±2.1 (P=0.001). Fifty-eight of the 318 patients had diabetes. We observed significantly higher HbA1c in diabetic than in non-diabetic patients preoperatively, whereas an insignificantly different HbA1c was observed postoperatively. Among those who had minimal reduction in BMI (0-9 kg/m2), we observed significantly higher HbA1c in diabetic than in non-diabetic patients, whereas among those who had large reduction in BMI (10-14 kg/m2) and (>14 kg/m2), we observed insignificant differences in HbA1c in diabetic than in non-diabetic patients. CONCLUSION: Being a diabetic patient was related to a significant reduction in HbA1c levels postoperatively. The study suggests that the reduction in HbA1c levels could be modified by BMI, wherein greater reduction in BMI leads to greater reduction in HbA1c levels.
RESUMO
PURPOSE: Oral health in cancer patients was known to influence the quality of life. However, the knowledge of possible factors associated with oral health in cancer patients is seriously lacking in Saudi Arabia. In this study, we aimed to determine the burden of adverse oral health in cancer patients and identify the associated factors for oral health problems. MATERIALS AND METHODS: A cross-sectional study design was used to recruit a total of 375 cancer patients who attended oncology outpatient clinics at King Abdulaziz Medical City - Riyadh (KAMC-R) by using a consecutive sampling technique. A self-reporting questionnaire was used to collect the sociodemographic information, clinical symptoms, and lifestyle factors of cancer patients. Furthermore, depression, anxiety, and stress were assessed by using Depression Anxiety and Stress Scale. The authors assessed the oral health complaints based on seven common conditions (bleeding gums, toothache, mouth ulcers, bruxism, xerostomia, problems affecting speech, and satisfactory dietary intake). Unadjusted and adjusted risk ratios (aRR) and 95% CIs for the factors associated with the number of oral complaints experienced were computed using Poisson regression model. RESULTS: The prevalence of oral health conditions experienced by cancer patients was 86.1% (95% CI: 82.2%-89.5%). Female sex (aRR=1.37, 95% CI: 1.05-1.78), low income (aRR=1.58, 95% CI: 1.23-2.04), smoking (aRR=1.29, 95% CI: 1.02-1.64), anxiety (aRR=1.75, 95% CI: 1.36-2.24), and stress (aRR=1.25, 95% CI: 1.00-1.55) were associated with increased risk of oral health problems in cancer patients (p≤0.05), whereas breast cancer patients experienced reduced risk (aRR=0.72, 95% CI: 0.56-0.93). CONCLUSION: Our study highlighted the significant burden of oral health problems in Saudi cancer patients at KAMC-R and identified several key associated factors for oral health to aid healthcare practitioners in improving cancer management practices.
RESUMO
BACKGROUND: Low levels of asthma control are reported in many countries worldwide. Improved knowledge of asthma control in the Middle East and Africa and predictive factors is needed to address this major public healthcare burden. OBJECTIVE: To assess the level of asthma control in patients attending a routine consultation for asthma in the Middle East and North Africa, and the relationship between level of control and patient and disease characteristics, adherence, and quality of life (QoL). METHODS: A large-scale cross-sectional epidemiological study (ESMAA: Assessment of Asthma Control in Adult Asthma Population in the Middle East and North Africa) was performed in adults suffering from asthma for at least 1 year and without an acute asthma episode within 4 weeks. Asthma control was assessed per the 2012 GINA guidelines and the ACT questionnaire. QoL and adherence were assessed with the SF-8 and Morisky questionnaires respectively. Predictive factors of asthma control were analysed with univariate and multivariate logistic regressions analyses. RESULTS: Overall 7236 eligible patients were included in 577 sites between June 2014 and December 2015 (median 10 patients/site). Mean age was 45 years (±14), 57% were female, mean BMI was 28.5â¯kg/m2 (±6.0), and 11% were active smokers. Reliever medication was prescribed in 96% of patients with 65% having fixed-dose combined inhaled corticosteroid plus long-acting beta agonists. Good medication adherence was reported in 24% of patients. Among 7179 patients evaluable for GINA, asthma was controlled in 29.4% (95% CI, 28.4%-30.5%), partly controlled in 29.1% (95% CI, 28.1%-30.2%), and uncontrolled in 41.5% (95% CI, 40.3% to 42.6). The mean global ACT score was 17.8 (±5.0), with 16% of patients considering their asthma as controlled. Poor medication adherence, active smoking, absence of medical insurance, lower level of education, or diagnosis at least 5 years earlier were significantly associated with uncontrolled asthma in multivariate analyses (pâ¯<â¯0.001). CONCLUSIONS: Asthma control in the Middle East and North Africa is unsatisfactory with less than one-third of asthma patients having controlled disease, highlighting the need to improve treatment access and medication adherence, along with better follow-up and education among healthcare providers and patients.

AIMS: The pathogenesis, viral localization and histopathological features of Middle East respiratory syndrome - coronavirus (MERS-CoV) in humans are not described sufficiently. The aims of this study were to explore and define the spectrum of histological and ultrastructural pathological changes affecting various organs in a patient with MERS-CoV infection and represent a base of MERS-CoV histopathology. METHODS AND RESULTS: We analysed the post-mortem histopathological findings and investigated localisation of viral particles in the pulmonary and extrapulmonary tissue by transmission electron microscopic examination in a 33-year-old male patient of T cell lymphoma, who acquired MERS-CoV infection. Tissue needle biopsies were obtained from brain, heart, lung, liver, kidney and skeletal muscle. All samples were collected within 45 min from death to reduce tissue decomposition and artefact. Histopathological examination showed necrotising pneumonia, pulmonary diffuse alveolar damage, acute kidney injury, portal and lobular hepatitis and myositis with muscle atrophic changes. The brain and heart were histologically unremarkable. Ultrastructurally, viral particles were localised in the pneumocytes, pulmonary macrophages, renal proximal tubular epithelial cells and macrophages infiltrating the skeletal muscles. CONCLUSION: The results highlight the pulmonary and extrapulmonary pathological changes of MERS-CoV infection and provide the first evidence of the viral presence in human renal tissue, which suggests tissue trophism for MERS-CoV in kidney.

BACKGROUND AND AIMS: A granuloma is a common pathological diagnosis in lung biopsies and is caused by a variety of etiologies. The aim of this study was to assess the etiology and frequency of different cases of lung granulomas. METHODS: The medical records of all patients who had lung granulomas between 2005 and 2013 were retrospectively reviewed. Based on the histological features of the granulomas, along with the clinical, laboratory, and radiological findings, an attempt was made to identify the etiology of the granuloma in each case. RESULTS: A total of 158 patients with lung biopsy specimens showing lung granulomas were identified. The histological findings revealed necrotizing granulomas in 92 (58%) of the cases and nonnecrotizing granulomas in 66 (42%). A definite etiology was determined in 133 cases (84%), whereas in 26 cases (16%), the etiology could not be identified despite an extensive workup. Infection was the most frequent cause of granuloma, accounting for 105 cases (66%). Mycobacterial tuberculosis (TB) was the type of infection that caused the largest number of granulomas, and was responsible for 100 cases (63%). Among the noninfectious etiologies of lung granuloma, sarcoidosis was the most common cause, accounting for 20 (13%) of the cases. CONCLUSIONS: Mycobacterial TB and sarcoidosis are the most common causes of lung granulomas in our region. In a substantial proportion of cases, the cause may not be identified despite an extensive workup.
RESUMO
This is the first guideline developed by the Saudi Thoracic Society for the diagnosis and management of noncystic fibrosis bronchiectasis. Local experts including pulmonologists, infectious disease specialists, thoracic surgeons, respiratory therapists, and others from adult and pediatric departments provided the best practice evidence recommendations based on the available international and local literature. The main objective of this guideline is to utilize the current published evidence to develop recommendations about management of bronchiectasis suitable to our local health-care system and available resources. We aim to provide clinicians with tools to standardize the diagnosis and management of bronchiectasis. This guideline targets primary care physicians, family medicine practitioners, practicing internists and respiratory physicians, and all other health-care providers involved in the care of the patients with bronchiectasis.
RESUMO
We report two cases of patients with biopsy-proven idiopathic pulmonary fibrosis (IPF) who were treated with new antifibrotic agent for pirfenidone for more than 12 months. Both cases developed cavitary pulmonary tuberculosis (TB) proven by positive sputum TB culture. Both cases were treated with standard anti-TB drugs for 9 months and had complete clinical and radiological resolution. To our knowledge, these are the first reported human cases of patients with IPF who have been on pirfenidone and developed cavitary pulmonary TB.
