RESUMO
BACKGROUND: In Saudi Arabia (SA), there has been an alarming increase in the prevalence of chronic kidney diseases (CKD) over the last three decades. Despite being one of the largest countries in the Middle East, renal conditions remain understudied, and there is limited data on their epidemiology and outcomes in SA. OBJECTIVES: To document the experience of establishing a local renal registry assessing the epidemiology of CKD and identifying potential areas for improving the quality and delivery of care for CKD patients. METHODS: This is a multi-center retrospective registry. Potential participants were identified through the ICD-10 codes from five hospitals serving the National Guard affiliates in SA. Patients aged ≥ 18 years treated in any National Guard hospital since 2010 for glomerulonephritis, CKD, or received hemodialysis, peritoneal dialysis, or renal transplant were enrolled. Once enrolled in the registry, patients were followed to the last visit date. RedCap was used to create and host the online registry platform. RESULTS: A total of 2,912 patients were included, and more than half were younger than 60 years old. Two-thirds of the patients were overweight (25%) or obese (37%). Glomerulonephritis was diagnosed in 10% of the patients, and dialysis-dependent and kidney transplant patients accounted for 31.4% and 24.4%, respectively. Hypertension and diabetes mellitus were detected among 52% and 43% of the participants, respectively. Hemodialysis was the most prevalent dialysis method, with patients spending 3.6 ± 0.4 h per session to receive this treatment. One in every five participants had a kidney biopsy taken (21%). Several barriers and facilitators of the success of this registry were identified. CONCLUSIONS: The KIND registry provides much-needed information about CKD in Saudi Arabia and serves as a model for future projects investigating the natural history and progression of the spectrum of renal diseases. Logistic and financial challenges to the sustainability of registries are identified and discussed.

Background: Surgical residency training is prominently demanding and stressful. This can affect the residents' wellbeing, work-life balance and increase the rates of burnout. We aimed to assess rates of satisfaction and burn-out among GS residents in the national training programs and provide a subsequent in-depth analysis of the potential reasons. Method: A sequential explanatory mixed-methods study was conducted using an online survey and virtual interviews. The validated abbreviated Maslach Burnout Inventory (aMBI) was used to assess burnout while satisfaction was assessed via 5-points Likert scale. Results: After excluding incomplete responses from the total 74 received, 53 were analyzed. The average participant age was 27.4 ± 2 years, with females comprising 52 % of the sample. Junior residents made up 58.5 %, and nearly half -45 %- considered quitting GS training. Moderate to high burnout rates were noted on each aMBI subscale, ranging from 41.7 % to 62.5 %. The majority of residents expressed dissatisfaction with the level of research engagement (81.1 %), supervision, and mentorship. However, operative exposure was a source of satisfaction. Dissatisfaction rates with intra-operative learning, academia, teaching, and clinical exposure were 62.3 %, 52.8 %, 50.9 %, and 35.8 %, respectively. Interviews revealed surgical case flow and a friendly work environment as major satisfaction sources. Conversely, lack of academic supervision and suboptimal hands-on training were major dissatisfaction sources. Conclusion: Dissatisfaction and burn-out is prevalent among national GS training programs. Sub-optimal educational delivery and low-quality hands-on operative exposure -rather than lack of exposure to cases- seem to be the culprit.
RESUMO
INTRODUCTION: The consequences of traumatic spine fracture (TSF) are complex and have a major burden on patients' social life and financial status. In this study, we aimed to investigate the return to work (RTW) after surgically treated TSFs, develop eventual predictors of delayed or failure to RTW, and assess narcotics use following such injuries. METHODS: This was a single-center retrospective cohort study that was performed in a tertiary care center. TSF patients who required surgical intervention from 2016 to 2021 were enrolled. Demographic, operative, and complication data, as well as narcotics use, were recorded. RTW was modeled using multivariate logistic regression analysis. RESULTS: Within the 173 patients with TSF, male patients accounted for 82.7%, and motor vehicle accidents were the most common mechanism of injury (80.2%). Neurologically intact patients represented 59%. Only 38.15% returned to work after their injury. Majority of the patients didn't use narcotics more than 1 week after discharge (93.1%). High surgical blood loss, operation time, and hospital length of stay were significantly associated with not returning to work. In multivariant regression analysis, every increase of 100 ml of surgical blood loss was found to decrease the chance of RTW by 25% (P = 0.04). Furthermore, every increase of one hour in operation time decreases the chance of RTW by 31% (P = 0.03). CONCLUSION: RTW is an important aspect that needs to be taken into consideration by health care providers. We found that age and high surgery time, blood loss, and hospital stay are significantly impacting patients' RTW after operated TSF.

Aim: To assess the efficacy and safety of Dipeptidyl Peptidase IV (DPP-4) inhibitors in patients with Type-2 Diabetes Mellitus (T2DM) and chronic kidney disease (CKD) using level 1 evidence. Methods: The Cochrane and PubMed databases were searched from inception until January 1, 2022. RCTs that studied the efficacy and safety of DPP-4 inhibitors in diabetic patients with CKD were included. The primary efficacy outcome was assessed as the mean difference between HbA1c at the beginning and the end of each study for each arm, and the primary safety outcome was assessed as the incidence of adverse events and severe adverse events in each study. Results: Twenty-one studies satisfied the pre-defined eligibility criteria. In assessing the efficacy of DPP-4 inhibitors in the treatment of T2DM and CKD, a total of 2917 patients under the DPP-4 inhibitors group and 2377 patients under the control group were included; The mean difference between the HbA1c of DPP-4 Inhibitor and the control group was -0.5295 with a 95% CI of -0.5337 to -0.5252. The included studies had high heterogeneity p < 0.00001 and I2 = 99%. In assessing the safety outcome and tolerability of DPP-4 inhibitors, a total of 8138 patients under the DPP-4 inhibitors group and 7517 patients under the control group were included; the odds ratio of adverse events between both groups was 0.9967 with a 95% CI of 0.9967 to 1.1047. The included studies had low heterogeneity p = 0.25 and I2 = 15%. The overall effect, Z = 0.06 (p = 0.95), was insignificant. Conclusion: Patients suffering from both T2DM and CKD exhibited a significantly enhanced glycemic control when treated with DPP-4 inhibitors in comparison to the control group. Furthermore, no significant difference in the incidence of adverse events was observed between the DPP-4 inhibitors and the control group.
RESUMO
OBJECTIVES: To evaluate the clinical and laboratory features, complications, and outcomes of patients with rhabdomyolysis in the Saudi population. METHODS: Retrospectives descriptive study of adult patients who presented to King Abdulaziz Medical City (KAMC) withrhabdomyolysis between January 2016 and December 2022. RESULTS: Most of the participants (84.5%) were male, with a median age of 41 years and a body mass index of 26.5 kg/m2. Medications, mainly statins (22.4%) and illicit drugs (15.5%), constituted the root causes of rhabdomyolysis in the cohort (44.8%). The most common presenting complaints were myalgia (63.8%) and fatigue (37.9%). More than one-third of the participants (32.8%) developed AKI, with 3 patients requiring temporary hemodialysis, and only 8.6% developed acute liver failure (ALF). Intensive care unit (ICU) admission was required for 10 patients (17.2%), and the overall mortality rate was 8.6%. Patients who developed complications (composite outcomes of AKI, ALF, multiorgan failure, or death) had significantly reduced kidney function and higher levels of blood urea nitrogen, anion gap, and uric acid upon admission than those who did not. CONCLUSION: This study offers a thorough understanding of clinical and laboratory features, causes, complications, and outcomes of rhabdomyolysis among Saudi patients. The insights gained enhance our understanding of rhabdomyolysis within this population, providing a foundation for future research and improvements in clinical management.

Background: Intraluminal thrombus (ILT) of the cervical arteries is an uncommon finding that can lead to acute or recurrent ischemic stroke. Currently, antithrombotic therapy in the form of antiplatelet and/or anticoagulation is considered the mainstay of treatment, but evidence of which one has a better outcome is lacking. Methods: A retrospective cohort study included 28 patients diagnosed with acute stroke or transient ischemic attack with ILT of the extracranial arteries from 2013 to 2022. The primary efficacy outcome was assessed as recurrent stroke, and the primary safety outcome was assessed as hemorrhagic complications. Secondary outcomes were assessed as the resolution of thrombi by CT angiography (CTA) and clinical improvement by the Modified Rankin Scale (mRS) and NIH Stroke Scale (NIHSS). Results: Out of 28 patients, more than half (57.1%; n = 16) were males with a mean age of 57.8 ± 9.5 years and an average BMI of 26.9 ± 4.5 kg/m2. As initial treatment, twenty-four patients received anticoagulation and four received antiplatelet agents. Recurrent strokes were found in four patients (14.29%), and all were initially treated with anticoagulation. One patient in the anticoagulation group had a significant retroperitoneal hemorrhage. None of the patients in the antiplatelets group had a recurrent stroke or bleeding event. Initial treatment with antiplatelet agents significantly improved the NIHSS on day 7 (P = 0.017). A significant improvement in NIHSS on day 90 was observed in the anticoagulant group (P = 0.011). In the follow-up CTA performed on 24 patients, 18 (75%) showed complete resolution (3 out of 3 (100%) in the antiplatelet group and 15 out of 21 (71.43%) in the anticoagulant group). Conclusion: Initial treatment with anticoagulants improves neurologic outcomes in patients with ILT-induced acute ischemic stroke but carries the risk of recurrent stroke and bleeding. However, initial treatment with dual antiplatelet agents appears to have comparable efficacy without sequelae, particularly in atherosclerosis-induced ILT.

Hemolytic uremic syndrome (HUS) is classically described as a triad of nonimmune hemolytic anemia, thrombocytopenia, and acute kidney injury. Atypical HUS (aHUS) is a rare variant of the disease, and it accounts for 5-10% of the cases. It has a poor prognosis, with a mortality rate exceeding 25% and a more than 50% chance of progressing into end-stage kidney disease (ESKD). Genetic or acquired dysregulation of the alternative complement pathway is highly implicated in the pathogenesis of aHUS. Multiple triggers for aHUS have been described in the literature, including pregnancy, transplantation, vaccination, and viral infections. Herein, we report a case of a previously healthy 38-year-old male who developed microangiopathic hemolytic anemia and severe kidney impairment one week after receiving the first dose of AstraZeneca SARS-CoV-2 vaccine. A diagnosis of aHUS was made after excluding other causes of thrombotic microangiopathies. Treatment with plasma exchange, prednisone, and rituximab (375 mg/m2) once weekly for four doses resulted in improvement of his hematological parameters. However, he progressed to ESKD.
RESUMO
Introduction: Dermatofibrosarcoma protuberans (DFSP) is a rare, slow-growing, and locally aggressive soft tissue tumor with a high recurrence rate and metastatic potential, even with the proper treatment. Methods: This was a retrospective (case series) study that took place at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia, to determine the outcomes of and appropriate margin excision for DFSP. All patients who were diagnosed with DFSP from 2016 to 2021 were included. The following variables were assessed: demographics, tumor characteristics, management options, and most importantly, whether patients were managed with an oncology-oriented approach or a non-oncology-oriented approach. Results: There were a total of seventeen patients with DFSP, four of whom had fibrosarcomatous differentiation (FS-DFSP). The majority (N = 13, 76.5%) of the patients were females. The lower extremities and back were the most common locations for DFSP, accounting for 47.1% and 23.5%, respectively. Only two (11.76%) patients had metastatic disease, one of whom had FS-DFSP. The minimum resection margin was 3 cm, and the maximum was 5 cm. Thirteen (76.47%) patients were managed with an oncology-oriented approach (Group I), 23% of whom had post-excision positive margins. However, all patients who were managed with a non-oncology-oriented approach (Group II) had positive margins post-excision. More than three-quarters (76.9%) of group I underwent wide resection. Split-thickness skin grafting and primary closure were the most commonly used reconstruction methods in groups I and II, respectively. The mean planned margins in groups I and II were 3.9 cm and 1.7 cm, respectively. Conclusion: The findings of this study suggest that a planned wide-margin excision with a minimum safe margin of 3-5 cm should be implemented to reduce the recurrence, metastasis, and need for further surgeries in patients with DFSP.
RESUMO
Objectives: Spinal cord injuries cause major disabilities and are devastating events for both patients and healthcare providers. Most traumatic spinal cord injuries (TSCIs) are due to motor vehicle accidents (MVAs). Neglected injuries result in complications and poor outcomes. Here, we investigated the causes, consequences, and outcomes of neglected TSCIs. Methods: This case series study was performed at King Abdulaziz Medical City, Riyadh, KSA. Of the 750 patients treated between February 2016 and February 2021, 18 patients met our inclusion criterion of neglected high-energy TSCI with neurological deficit, necessitating surgical intervention more than 14 days after the index trauma. Results: Of the 18 patients with neglected TSCIs, 72.2% were men. The patients' mean age at the time of injury was 36.8 years, 77.8% were from outside Riyadh, and all patients had MVA-induced TSCIs, 88.9% of which were attributable to delayed referral to a tertiary center. The mean duration of neglect was 43 days, and the longest duration was 125 days. The most common site of injury was the thoracolumbar region (55.5%). The American Spinal Injury Association impairment scale score improved in two patients. Bed sores occurred in 55.5%, and deep vein thrombosis occurred in 27.8% of patients. Postoperatively, 77% of patients required intensive care unit admission. Most patients (12) did not receive specialized spinal cord injury rehabilitation postoperatively. Conclusion: Early referral of patients with TSCIs is crucial to prevent short- and long-term complications.
RESUMO
Malignant peritoneal mesothelioma (MPM) is a rare malignancy, presenting with non-specific and potentially-misleading manifestations. It represents a diagnostic pitfall as it mimics ovarian carcinoma. Maintaining a low diagnostic threshold, obtaining a detailed history, and utilizing immunohistochemical markers to diagnose MPM is crucial as early diagnosis and treatment might improve survival.
RESUMO
BACKGROUND: Venous thromboembolism (VTE) represents a considerable burden on cancer patients' survival and quality of life, but this burden varies based on the patient's baseline characteristics and cancer-related factors. Although solid evidence on the predictors and effect of VTE in cancer patients exists. AIM: To evaluate VTE rate, morbidity, and mortality to develop parameters that could predict VTEs and their associated mortality in patients with multiple primary malignancies (MPMs). METHOD AND RESULTS: This was a retrospective cohort study that took place at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia. Two hundred and forty-two patients with at least two biopsy-proven malignancies and had at least 3 months of follow-up after MPMs diagnosis were included. VTE was diagnosed in 14.5% of the cases, two-thirds of which were deep vein thrombosis. VTE was significantly associated with a higher mortality and worse survival. Predictors of VTE after MPMs diagnosis were a high ECOG performance status at MPMs diagnosis, a metastatic first primary malignancy, and ICU admission after MPMs diagnosis. Having a GI or hematological malignancy as the second primary malignancy, a high D-dimer at ICU admission, and palliative care referral were significantly associated with a higher mortality in patients who had VTE. CONCLUSION: VTE was diagnosed in 14.5% of patients with MPMs and it significantly compromises their survival. We believe that these results might be of particular benefit since the phenomenon of MPMs is becoming more frequently encountered.

BACKGROUND: Data on outcomes of renal transplantation in the Kingdom of Saudi Arabia (KSA) is limited. We describe renal transplant experience in one of the largest referral centers for renal transplants in KSA. METHODS: This is a retrospective cohort study of patients who underwent kidney transplantation at King Abdulaziz Medical City (KAMC) from January 2016 to July 31, 2019, with at least one year of follow-up post-transplantation. RESULTS: One hundred ninety-four individuals were identified and included in the analysis. The mean age of the renal transplant cohort was 45 years with an average pre-transplant body mass index of 26.1 kg/m2. The most common comorbidities were hypertension (77.3%) and diabetes mellitus (34.5%). The most common etiology of end-stage kidney disease (ESKD) was unknown (49.0%) followed by Lupus nephropathy (16.0%). Central venous catheters were the predominant dialysis access (56.2%). Living-related kidney donation was the commonest source of kidney transplantation (61.3%), followed by deceased donor renal transplantation (22.7%). Anti-thymocytes globulin (ATG) was the predominant induction agent (57.7%) and nearly all patients received tacrolimus-based maintenance immunosuppression. Mean serum creatinine at the time of discharge was 109 umol/l. Delayed graft function was observed in 6.7% of our patients. The most common medical complications were urinary tract infection (26.3%). Post-transplant surgical complications occurred at a low rate. CONCLUSION: Our study demonstrated a successful renal transplant experience among a relatively healthy cohort and identifies potential gaps, particularly the high rate of central venous catheters, the frequent lack of clear etiology of ESKD, the low rate of pre-emptive transplant, and deceased donors. Further studies are needed to evaluate and close these gaps.
RESUMO
Background Similar to coronavirus disease 2019 (COVID-19), the pathogenesis of inflammatory rheumatic diseases includes cytokines dysregulation and increased expression of pro-inflammatory cytokines. Although current data from international studies suggest that rheumatic diseases are associated with a higher risk of COVID-19 infection and worse outcomes, there is limited literature in Saudi Arabia. This study aims to evaluate the outcomes and length of hospital stay of COVID-19 patients with inflammatory rheumatic diseases in Saudi Arabia. Method This was a single-center retrospective cohort study that included 122 patients with inflammatory rheumatic diseases and documented coronavirus disease 2019 (COVID-19) infection from 2019 to 2021. Patients with suspected COVID-19 infection, non-inflammatory diseases, such as osteoarthritis, or inflammatory diseases but without or with weak systemic involvement, such as gout, were excluded. Results The vast majority (81.1%) of the patients were females. Rheumatoid arthritis was the most common primary rheumatological diagnosis. The admission rate was 34.5% with an overall mortality rate of 11.5%. Number of episodes of COVID-19 infection, mechanical ventilation, cytokine storm syndrome, secondary bacterial infection, number of comorbidities, rituximab, diabetes mellitus, hypertension, chronic kidney disease, and heart failure were significantly associated with a longer hospital stay. Additionally, hypertension, heart failure, rituximab, mechanical ventilation, cytokine storm syndrome, and secondary bacterial infection were significantly associated with higher mortality. Predictors of longer hospitalization were obesity, number of episodes of COVID-19 infection, mechanical ventilation, number of comorbidities, and chronic kidney disease, whereas, hypertension was the only predictor of mortality. Conclusion Obesity, number of episodes of COVID-19 infection, mechanical ventilation, number of comorbidities, and chronic kidney disease were significantly associated with higher odds of longer hospitalization, whereas, hypertension was significantly associated with higher odds of mortality. We recommend that these patients should be prioritized for the COVID-19 vaccine booster doses, and rituximab should be avoided unless its benefit clearly outweighs its risk.
RESUMO
Sarcoidosis is an immune-mediated, inflammatory, non-caseating-granulomatous disease that can virtually infiltrate any organ. Cardiac sarcoidosis is a leading cause of death in patients with sarcoidosis. Its clinical presentation is highly heterogenous and unpredictable, ranging from asymptomatic to life-threatening conduction disturbances, such as ventricular arrhythmias, and heart failure. Herein, we report a case of isolated cardiac sarcoidosis presenting as sinus bradycardia with first-degree atrioventricular block and an episode of non-sustained polymorphic ventricular tachycardia in a 42-year-old male with non-ischemic cardiomyopathy. He was diagnosed by cardiac magnetic resonance imaging and positron emission tomography with fluorodeoxyglucose and treated with oral prednisone.
RESUMO
Endocarditis is an extremely rare complication of Salmonellosis with an incidence of 0.2-0.4%. It is a destructive and invasive infection that follows a highly complicated course and carries a high mortality rate that exceeds 45%. Multiple predisposing factors for Salmonella endocarditis have been described in the literature, including human immunodeficiency virus infection, congenital heart diseases, and the presence of a prosthetic valve. Herein, we report a case of Salmonella prosthetic valve endocarditis complicated by splenic infarction and aortic pseudoaneurysm presenting as a month-long history of fluctuating fever, chills, and rigors, accompanied by occasional cough and shortness of breath in a 55-year-old female with aortic and mitral valves replacement and multiple comorbidities. She was diagnosed by multiple radiographic studies and successfully treated with the Commando procedure and a long course of IV antibiotics.
RESUMO
Purpose Owing to the difficulty of establishing a screening program for scoliosis and back pain, along with their disabling consequences and the lack of local prevalence rates, we sought to study the prevalence of scoliosis and back pain in adolescents in Saudi Arabia and the burden reported by the affected age group on the health system. Materials and methods A school-based, cross-sectional pilot study covering all school districts in Riyadh, Saudi Arabia, was conducted. Students between 12 and 18 years of age were included. Students with any spinal or neurological disorders were excluded. Physical examinations to screen for scoliosis and student-filled questionnaires to assess back pain and health-related quality of life were performed. Results Of the 700 students, 591 met the inclusion criteria. High suspicion of adolescent idiopathic scoliosis (AIS) was considered in 174 students (29.44%). In addition, 45.42% of the students had a history of back pain. The Oswestry Disability Index showed that 87 students had disabilities. The average Scoliosis Research Society-22 score was 3 out of 5. A significant difference was found in the self-image and mental health domains for AIS (p = 0.04, p = 0.02, respectively). Age showed a significant increase in the odds ratio of a positive physical exam for every increase of one year in age (p < 0.01). Conclusion Identifying the prevalence rates and early associated factors during adolescence would help lower the burden on the health system and benefit public health in general. A nationwide study is required to identify the relationship between scoliosis and back pain.
