RESUMO

Purpose: To assess the prevalence of dyslipidemia and its determinants among adults in the Jazan region of Saudi Arabia. Methods: This data was collected during interviews utilizing a structured questionnaire. The questionnaire measured the demographics, diagnosis with dyslipidemia, and distribution of dyslipidemia determinants among the sample, including dietary habits and lifestyle practices. A chi-square test was used to examine the statistical difference between the characteristics of individuals who had reported checking their lipid profile to those who reported never performing a lipid profile check-up among participants not diagnosed with dyslipidemia. Results: The current study included a total of 244 participants. The median age of the participants was 27 years, most participants were female (66.8%), and about 59% had a university education or above. Approximately 40% of the participants had ever had their lipid profile checked, 20.1% of the participants had been diagnosed with dyslipidemia, and 20.9% had family history of dyslipidemia. Most of the undiagnosed participants (79.9%) had more than one risk factor for developing dyslipidemia. All the participants without a dyslipidemia diagnosis had not been meeting the recommended levels of physical activity, and more than half consumed a high-fat diet. The results of the inferential analysis indicate that among those who had not been diagnosed with dyslipidemia, participants who were older than 27 years, male, unemployed, married, had a university education or above, and a minimum monthly income of 5000 Saudi Arabia Riyals were more likely to check their lipid profile compared to other groups (p-values <0.05). Conclusion: The findings suggest that most of the participants who had not been diagnosed with dyslipidemia are at high risk of developing dyslipidemia. About 60% of the participants had never checked their lipid profile, suggesting a need to promote routine lipid profile check-ups among individuals at high-risk for dyslipidemia.

RESUMO

BACKGROUND: Saudi Arabia's Vision 2030 aims to reform health care across the Kingdom, with health technology assessment being adopted as one tool promising to improve the efficiency with which resources are used. An understanding of the opportunity costs of reimbursement decisions is key to fulfilling this promise and can be used to inform a cost-effectiveness threshold. This paper is the first to provide a range of estimates of this using existing evidence extrapolated to the context of Saudi Arabia. METHODS AND MATERIALS: We use four approaches to estimate the marginal cost per unit of health produced by the healthcare system; drawing from existing evidence provided by a cross-country analysis, two alternative estimates from the UK context, and based on extrapolating a UK estimate using evidence on the income elasticity of the value of health. Consequences of estimation error are explored. RESULTS: Based on the four approaches, we find a range of SAR 42,046 per QALY gained (48% of GDP per capita) to SAR 215,120 per QALY gained (246% of GDP per capita). Calculated potential central estimates from the average of estimated health gains based on each source gives a range of SAR 50,000-75,000. The results are in line with estimates from the emerging literature from across the world. CONCLUSION: A cost-effectiveness threshold reflecting health opportunity costs can aid decision-making. Applying a cost-effectiveness threshold based on the range SAR 50,000 to 75,000 per QALY gained would ensure that resource allocation decisions in healthcare can in be informed in a way that accounts for health opportunity costs. LIMITATIONS: A limitation is that it is not based on a within-country study for Saudi Arabia, which represents a promising line of future work.


Healthcare in Saudi Arabia is undergoing wide-ranging reform through Saudi Arabia's Vision 2030. One aim of these reforms is to ensure that money spent on healthcare generates the most improvement in population health possible. To do this requires understanding the trade-offs that exist: funding one pharmaceutical drug means that same money is not available to fund another pharmaceutical drug. This is relevant whether the new drug would be funded from within the existing budget for healthcare or from an expansion of it. If the drugs apply to the same patient population and have the same price, the question is simply, "which one generates more health?" In reality, we need to compare pharmaceutical drugs for different diseases, patient populations, and at a range of potential prices to understand whether the drug in question would generate more health per riyal spent than what is currently funded by the healthcare system. This paper provides the first estimates of the amount of health, measured in terms of quality adjusted life years (QALYs), generated by the Saudi Arabian healthcare system. We find that the healthcare system generates health at a rate of one QALY produced for every 50,000­75,000 riyals spent (58­86% of GDP per capita). Using the range we estimate to inform cost-effectiveness threshold can aid decision-making.

RESUMO

Adaptable and consistent neural function relies at least in part on the ongoing repair of oxidative damage that can accumulate in the brain over a lifespan. To determine whether forebrain neuron-targeted knockout of AP endonuclease 1 (APE1), a critical enzyme in the base excision DNA repair pathway, contributes to neuronal impairments, we generated APE1 conditional knockout mice under the control of the CamKIIα promotor (APE1 cKO). Spatial learning and memory were tested using the Morris water maze. Synaptic markers, including synapsin, vGLUT, GABA1, and GAD were immunostained and quantified. Dendritic morphology and number were characterized using Golgi staining. Long-term potentiation (LTP) was measured in slices from the 6-month-old brain. APE1 cKO mice did not significantly differ from WT mice in the learning phase of the Morris water maze, but performed significantly worse during the memory phase of the Morris water maze. vGLUT, GABA1, and GAD immunostaining was significantly decreased in APE1 cKO mice without concomitant changes in the number of synapsin-positive structures, suggesting that neural networks may be impaired but not at the level of total presynaptic structures. Dendrites were reduced both in number and length of spines in APE1 cKO mice. APE1 cKO brain slices exhibited decreased LTP induction compared to WT brain slices. Together, these data indicate that the conditional loss of APE1 in forebrain neurons leads to a phenotype consistent with expedited brain aging.

RESUMO

Background Lung cancer is the most fatal malignancy worldwide, characterized by uncontrolled growth in the tissue of the lung(s). The diagnosis of lung cancer depends on the medical history of the patient, along with the physical examination, and various imaging studies. Furthermore, sputum cytology, thoracentesis, or a tissue and liquid biopsy can be examined. The TNM (tumor size, lymph nodes, and metastasis) system is used for staging and grading lung cancer. This study aimed to evaluate the role of tissue vs liquid biopsy in the clinical management of adenocarcinoma, at King Abdulaziz Medical City, Riyadh. Methods In this cross-sectional study, all adenocarcinoma patients treated between January 2016 to December 2018 were included using consecutive sampling. The participants were ≥ 18 years old patients with histologically confirmed adenocarcinoma (stage IIIb/IV) regardless of the mutation status. This data was collected through chart review. Data analysis was performed using the IBM Statistical Software for Social Sciences (SPSS) software, version 22 (IBM SPSS Statistics for Windows, Armonk, NY).  Results A total of 58 participants were included in the analysis. All of them had undergone a tissue biopsy, while only 16 patients underwent liquid biopsy. Out of all patients, 26% of patients had tissue biopsy-related complications (TBRC), with pneumothorax being the most common complication. Single gene testing for epidermal growth factor receptor (EGFR) for patients who underwent tissue biopsy showed a 35% mutation rate. For the anaplastic lymphoma kinase (ALK) gene, 13% were found to be mutated; for the ROS proto-oncogene 1 (ROS1) gene, only 7% were seen to be mutated. For a panel of 12 genes, 25% had the tumor protein 53 (TP53) gene mutation and 39% had the gene Kirsten rat sarcoma viral oncogene homolog (KRAS) mutations. For patients who underwent a liquid biopsy, 20% had the TP53 mutation, 43% had the EGFR mutations on a single gene test and 42% on a panel test, and 10% had the KRAS mutation. Conclusion We found that tissue and liquid biopsy showed genetic mutations, particularly with EGFR, TP53, and KRAS genes, among adenocarcinoma patients. Identifying genetic changes in adenocarcinoma patients is essential for charting a targeted therapy. Primary EGFR mutations and rearrangements of ALK or ROS1 are the only gene mutations that can be done with specific tyrosine kinase inhibitors available for clinical practice. Therefore, we recommend further studies to evaluate the role of tissue and liquid biopsy in clinical practice.

RESUMO

The abdominal cocoon is a rare clinical entity characterized by a thick fibrocollagenous membrane encasing the intestinal loops. Despite its rarity, the abdominal cocoon is one of the most serious complications of peritoneal dialysis. We report the case of a 45-year-old man, with end-stage renal disease on peritoneal dialysis resulting from systemic lupus erythematosus, who presented to the emergency department with progressive abdominal pain for the last two weeks. The pain was associated with nausea, vomiting, abdominal distension, and decreased bowel motion. Upon examination, the vital signs were within the normal limits. Abdominal examination revealed a distended abdomen with generalized tenderness. There was evidence of ascites as indicated by the positive shifting dullness test. The bowel sounds were of increased frequency and intensity. The laboratory findings were non-contributory. The patient underwent an abdominal computed tomography scan that demonstrated a cluster of small intestinal loops in the middle of the abdomen with a surrounding thick and calcified membrane. This made the diagnosis of the abdominal cocoon. The patient underwent an operation to resect the fibrocollagenous membrane. The patient reported improvement after the operation. No recurrence was noted after three months of follow-up. Abdominal cocoon is a very rare complication of peritoneal dialysis. The diagnosis of abdominal cocoon should be kept in mind when the physician encounters a patient with peritoneal dialysis who presented with non-specific and unexplained gastrointestinal symptoms.

RESUMO

Senescence-associated alterations in microglia may have profound impact on cerebral homeostasis and stroke outcomes. However, the lack of a transcriptome-wide comparison between young and aged microglia in the context of ischemia limits our understanding of aging-related mechanisms. Herein, we performed RNA sequencing analysis of microglia purified from cerebral hemispheres of young adult (10-week-old) and aged (18-month-old) mice five days after distal middle cerebral artery occlusion or after sham operation. Considerable transcriptional differences were observed between young and aged microglia in healthy brains, indicating heightened chronic inflammation in aged microglia. Following stroke, the overall transcriptional activation was more robust (>13-fold in the number of genes upregulated) in young microglia than in aged microglia. Gene clusters with functional implications in immune inflammatory responses, immune cell chemotaxis, tissue remodeling, and cell-cell interactions were markedly activated in microglia of young but not aged stroke mice. Consistent with the genomic profiling predictions, post-stroke cerebral infiltration of peripheral immune cells was markedly decreased in aged mice compared to young mice. Moreover, post-ischemic aged microglia demonstrated reduced interaction with neighboring neurons and diminished polarity toward the infarct lesion. These alterations in microglial gene response and behavior may contribute to aging-driven vulnerability and poorer recovery after ischemic stroke.

RESUMO

RATIONALE: Angiogenesis promotes neurological recovery after stroke and is associated with longer survival of stroke patients. Cerebral angiogenesis is tightly controlled by certain microRNAs (miRs), such as the miR-15a/16-1 cluster, among others. However, the function of the miR-15a/16-1 cluster in endothelium on postischemic cerebral angiogenesis is not known. OBJECTIVE: To investigate the functional significance and molecular mechanism of endothelial miR-15a/16-1 cluster on angiogenesis in the ischemic brain. METHODS AND RESULTS: Endothelial cell-selective miR-15a/16-1 conditional knockout (EC-miR-15a/16-1 cKO) mice and wild-type littermate controls were subjected to 1 hour middle cerebral artery occlusion followed by 28-day reperfusion. Deletion of miR-15a/16-1 cluster in endothelium attenuates post-stroke brain infarction and atrophy and improves the long-term sensorimotor and cognitive recovery against ischemic stroke. Endothelium-targeted deletion of the miR-15a/16-1 cluster also enhances post-stroke angiogenesis by promoting vascular remodeling and stimulating the generation of newly formed functional vessels, and increases the ipsilateral cerebral blood flow. Endothelial cell-selective deletion of the miR-15a/16-1 cluster up-regulated the protein expression of pro-angiogenic factors VEGFA (vascular endothelial growth factor), FGF2 (fibroblast growth factor 2), and their receptors VEGFR2 (vascular endothelial growth factor receptor 2) and FGFR1 (fibroblast growth factor receptor 1) after ischemic stroke. Consistently, lentiviral knockdown of the miR-15a/16-1 cluster in primary mouse or human brain microvascular endothelial cell cultures enhanced in vitro angiogenesis and up-regulated pro-angiogenic proteins expression after oxygen-glucose deprivation, whereas lentiviral overexpression of the miR-15a/16-1 cluster suppressed in vitro angiogenesis and down-regulated pro-angiogenic proteins expression. Mechanistically, miR-15a/16-1 translationally represses pro-angiogenic factors VEGFA, FGF2, and their receptors VEGFR2 and FGFR1, respectively, by directly binding to the complementary sequences within 3'-untranslated regions of those messenger RNAs. CONCLUSIONS: Endothelial miR-15a/16-1 cluster is a negative regulator for postischemic cerebral angiogenesis and long-term neurological recovery. Inhibition of miR-15a/16-1 function in cerebrovascular endothelium may be a legitimate therapeutic approach for stroke recovery.

RESUMO

Fosfomycin (FMT) was first isolated in 1969 and has gained popularity in the past few decades, specifically in the treatment of uncomplicated urinary tract infection (UTI). A retrospective study was undertaken to study the pattern of FMT use in our outpatient clinics. Subjects were divided into guideline compliant (GC) and non-guideline compliant (NGC) groups, based on available guidelines. More than half of the subjects (51, 51%) fall in the NGC group. Diabetes was an independent risk factor for inappropriate FMT prescription. This represented an opportunity for antimicrobial stewardship in treating diabetic patients with uncomplicated UTI when this agent is chosen.

RESUMO

BACKGROUND: ß-Lactamase resistance among certain Gram-negative bacteria has been associated with increased mortality, length of hospitalization, and hospital costs. AIM: To identify and critically appraise existing clinical prediction models of extended-spectrum ß-lactamase-producing Enterobacteriaceae (ESBL-EKP) infection or colonization. METHODS: Electronic databases, reference lists, and citations were searched from inception to April 2018. Papers were included in any language describing the development or validation, or both, of models and scores to predict the risk of ESBL-EKP infection or colonization. FINDINGS: In all, 1795 references were screened, of which four articles were included in the review. The included studies were carried out in different geographical locations with differing study designs, and inclusion and exclusion criteria. Most if not all studies lacked external validation and blinding of reviewers during the evaluation of the predictor variables and outcome. All studies excluded missing data and most studies did not report the number of patients excluded due to missing data. Fifteen predictors of infection or colonization with ESBL-EKP were identified. Commonly included predictors were previous antibiotic use, previous hospitalization, transfer from another healthcare facility, and previous procedures (urinary catheterization and invasive procedures). CONCLUSION: Due to limitations and variations in the study design, clinicians would have to take these differences into consideration when deciding on how to use these models in clinical practice. Due to lack of external validation, the generalizability of these models remains a question. Therefore, further external validation in local settings is needed to confirm the usefulness of these models in supporting decision-making.

RESUMO

BACKGROUND: A large number of Saudi athletes are recently shown to use androgenic anabolic steroid (AAS) products to achieve rapid muscle growth without realizing the serious health risks of these drugs. Aim of this study was to elucidate the side effects encountered with prolonged use of AAS products by Saudi athletes. METHODS: A cross-sectional study was conducted, in which 16 regular gym members, 12 of them used AAS, were asked to answer a questionnaire and provide blood samples following current AAS course completion. Hemoglobin, serum proteins, lipid profile and hematological parameters were measured. Meanwhile, the parameters of kidneys, liver, heart, and immune system function were monitored. RESULTS: The subjects reported taking a 3-month course of an AAS comprising three compounds (testosterone enanthate, nandrolone decanoate and methandienone). A two-week gap separated every two courses, during which tamoxifen citrate (40 mg per day) and clomiphene citrate (10 mg per day) were taken to control serum testosterone levels. The intake of AAS one course had remarkable effects on some parameters related to kidney function. However, AAS three courses or more treatments showed abnormal liver and heart enzymes. Moreover, endogenous testosterone levels decreased dramatically with prolonged use of AAS (more than 10 courses). Alpha 2 protein increased by taking more than 10 courses, which might cause acute phase reactant of liver infection or inflammation. CONCLUSIONS: AAS products must be controlled by Saudi ministry of health and should not be taken randomly without the supervision of the healthcare professional.

RESUMO

BACKGROUND: The Kingdom of Saudi Arabia has shown steady growth in the dental workforce over the last 20 years. Although the number of dental colleges has significantly increased in the last decade, there is not any study so far that described the status of the licensed dentist workforce in the kingdom. The present study aimed to explore the demographic distribution and professional characteristics of licensed dentist workforce in Saudi Arabia. METHODS: This was a descriptive cross-sectional study using the Saudi Commission for Health Specialties (SCFHS) database to identify the number of licensed dentists in Saudi Arabia as well as their professional and demographic characteristics as of December 2016. The data was categorized based on gender, nationality, dental specialty, health sector, geographic location, and professional rank. RESULTS: The number of licensed dentists working in the kingdom as of December 2016 was 16887 dentists, and the vast majority of them are professionally registered as general dentists (70.27%). The percentage of general dentists among the professionally registered female dentists is significantly higher than their male counterparts (79.71% vs. 64.80%; P < 0.001). Only 22.08% of the dentists working in the kingdom are Saudi. Most of the dentist workforce in the kingdom are male (61.06%). The mean age of the Saudi dentists is slightly but significantly younger than non-Saudi dentists (37.7 vs. 40.7 years; P < 0.001). Over 80% of the Saudi dentists are working in the regions of Riyadh, Makkah, and Eastern province. About 66% of the Saudi dentists are working in the public health sector in comparison to only 20.46% of the non-Saudi dentists (P < 0.001). CONCLUSIONS: Most of the dental care in Saudi Arabia is provided by non-Saudi dentists in both private and public health sectors. With the rising unemployment rate among Saudi dentists, the governmental bodies that are responsible of dental labor market regulations such as the ministries of health, economy and planning, and labor should come up with a policy to gradually but carefully replace the non-Saudi dentists in both public and private sectors with Saudi dentists.

RESUMO

BACKGROUND AND PURPOSE: Dysregulation of the miR-15a/16-1 cluster in plasma has been reported in patients with stroke as a potential biomarker for diagnostic and prognostic use. However, the essential role and therapeutic potential of the miR-15a/16-1 cluster in ischemic stroke are poorly understood. This study is aimed at investigating the regulatory role of the miR-15a/16-1 cluster in ischemic brain injury and insight mechanisms. METHODS: Adult male miR-15a/16-1 knockout and wild-type mice, or adult male C57 BL/6J mice injected via tail vein with the miR-15a/16-1-specific inhibitor (antagomir, 30 pmol/g), were subjected to 1 hour of middle cerebral artery occlusion and 72 hours of reperfusion. The neurological scores, brain infarct volume, brain water content, and neurobehavioral tests were then evaluated and analyzed. To explore underlying signaling pathways associated with alteration of miR-15a/16-1 activity, major proinflammatory cytokines were measured by quantitative polymerase chain reaction or ELISA and antiapoptotic proteins were examined by Western blotting. RESULTS: Genetic deletion of the miR-15a/16-1 cluster or intravenous delivery of miR-15a/16-1 antagomir significantly reduced cerebral infarct size, decreased brain water content, and improved neurological outcomes in stroke mice. Inhibition of miR-15a/16-1 significantly decreased the expression of the proinflammatory cytokines interleukin-6, monocyte chemoattractant protein-1, vascular cell adhesion molecule 1, tumor necrosis factor alpha, and increased Bcl-2 and Bcl-w levels in the ischemic brain regions. CONCLUSIONS: Our data indicate that pharmacological inhibition of the miR-15a/16-1 cluster reduces ischemic brain injury via both upregulation of antiapoptotic proteins and suppression of proinflammatory molecules. These results suggest that the miR-15a/16-1 cluster is a novel therapeutic target for ischemic stroke.

RESUMO

OBJECTIVES: Human papillomavirus (HPV)-associated cancers disproportionately affect those infected with HIV despite effective combination antiretroviral therapy (cART). The primary aim of this study was to quantify HPV16 and HPV52 E6-specific interferon (IFN)-γ enzyme-linked immunospot (ELISPOT) T-cell responses, a correlate of protective immunity, in the first year following cART initiation and subsequently in those patients with suboptimal (sIR) and optimal (oIR) immune reconstitution. METHODS: Ninety-four HIV-infected patients were recruited to the study; a longitudinal cohort of patients recruited just prior to commencing cART and followed up for 48 weeks (n = 27), and a cross-sectional cohort (n = 67) consisting of patients with sIR (CD4 T-cell count < 350 cells/µL) and oIR (CD4 T-cell count > 500 cells/µL) after a minimum of 2 years on cART. Controls (n = 29) consisted of HIV-negative individuals. IFN-γ ELISPOT responses against HPV16 and HPV52 E6 were correlated to clinical characteristics, anal and oral HPV carriage, T-cell maturational subsets, markers of activation, senescence and T-regulatory cells. RESULTS: HPV16 and HPV52 E6-specific T-cell responses were detected in only one of 27 patients (3.7%) during the initial phase of immune recovery. After at least 2 years of cART, those who achieved oIR had significantly higher E6-specific responses (9 of 34; 26.5%) compared with those with sIR (2 of 32; 6.3%) (P = 0.029). Apart from higher CD4 T-cell counts and lower CD4 T-cell activation, no other immunological correlates were associated with the detection of HPV16 and HPV52 E6-specific responses. CONCLUSIONS: HPV16 and HPV52 E6-specific IFN-γ T-cell responses, a correlate of protective immunity, were detected more frequently among HIV-infected patients who achieved optimal immune recovery on cART (26.5%) compared with those with suboptimal recovery (6.3%).

RESUMO

In this cross-sectional study, we evaluated factors that affected the perceived value of medication rating Web sites to 284 people aged ≥ 60 years who were taking prescription medications. The Patient Reviews of Medication Experience (PROMEX) questionnaire score, which assessed participant opinions about the value of online reviews of medications, was positively associated with preference to share health care decision making with the health care provider and negatively associated with the Physical Component Summary (PCS-12) and Mental Component Summary scores of the Short Form 12 health survey. The Primary Care Assessment Survey Communication score, which measured participant satisfaction with the communication from the health care provider, was positively associated with PCS-12 and health literacy. In summary, older adults who had poor physical and mental health-related quality of life were more likely to believe that medication rating Web sites were useful and helpful in facilitating communication with health care providers.

RESUMO

Cryptococcal meningitis is a rare occurrence in systemic lupus erythematosus (SLE). The risk factors of developing this infection are duration of SLE, intensity of glucocorticoid use, and SLE-related intrinsic immune abnormalities. Early recognition and prompt initiation of antifungals can prevent complications and improve survival. There is a dearth of evidence with regards to optimal treatment of cryptococcosis in non-HIV infected and non-transplant patients. The general consensus is to follow treatment guidelines for HIV-positive patients with cryptococcal meningitis. We describe a girl with active SLE and cryptococcal meningitis, and discuss the diagnostic and therapeutic challenges faced in this case.

RESUMO

In the past 5 y, the number of computed tomography (CT) studies has doubled at Dubai Health Authority hospitals. This situation, along with patient's overdoses reported internationally, has prompted action to establish a system to manage patient doses incurred due to medical imaging practices. In this work, the authors aim to homogenise dose reporting to monitor radiation dose levels and facilitate the establishment of local and national dose reference levels. The two hospitals enrolled in this study are equipped with three CT systems (two 4 slices and one 64 slices). Through the Picture Archive and Communication Systems (PACS) tracking system, it is mandatory to fill CT patient doses in radiology information system (RIS). Dose length product (mGy cm) was recorded for 2502 adult and 178 paediatric patients. All patients' dosimetry data were collected from the RIS by Cogonos statistical software. The PACS data were reviewed to exclude incomplete data. Average and range of effective doses for adult and paediatric patients were calculated using an appropriate weighting factor. Individual accumulated effective doses for adult and paediatric patients were calculated for 4s-scanner-1 only. Adult average effective doses for the head (1482 exams) were 1.23 ± 0.58, 2.84 ± 0.83 and 2.98 ± 1.103 mSv, the chest (545 exams) were 5.39 ± 1.63, 21.85 ± 5.63 and 18.19 ± 3.22 mSv and for the abdomen and pelvis (1183 exams) were 10.85 ± 4.26, 25.66 ± 8.83 and 26.46 ± 13.75 mSv for 4s-scanner-1, 4s-scanner-2 and 64 s, respectively. The paediatric average effective dose for the head (127 exams) was 1.77 ± 0.82 mSv, for the chest (22 exams) was 3.3 ± 1.29 mSv and for the abdomen and pelvis (27 exams) was 6.16 ± 2.64 mSv. Results of individual accumulated effective doses for adult and paediatric patients were presented. PACS dose reporting facilitated dosimetry clinical auditing. Effective doses obtained in this work demonstrated that the results of one scanner were within the international dose levels while the other two scanners were higher. Technical actions are recommended to standardise the dose levels.
