Jurnal Penyakit Dalam Indonesia

Introduction. Patients with autoimmune rheumatic diseases are known to be more vulnerable to severe and critical infections, including COVID-19. Although it is no longer classified as a pandemic, SARS- CoV-2 infection still persists, and several surges of cases have been reported, including in Indonesia. To date, no data are available regarding the prevalence of severe and critical COVID-19 at admission in patients with autoimmune rheumatic diseases in Indonesia and the associated factors. This study aimed to determine the prevalence of severe and critical COVID-19 at admission in patients with autoimmune rheumatic diseases at Dr. Cipto Mangunkusumo National General Hospital, …

Atrial Fibrillation In Athletes: Mechanisms, Management, And Future Directions, Ibrahim Alameh, Ghina Al Fout, Michael D. Ezekowitz, Mohammed Kamareddine

Department of Medicine Faculty Papers

BACKGROUND: High-volume endurance training may shift exercise from cardioprotective to arrhythmogenic, increasing the risk of atrial fibrillation (AF) in healthy athletes.

CASE SUMMARY: A 38-year-old marathon runner with a 15-year history of high-intensity endurance training presented with episodic palpitations and reduced athletic performance. Electrocardiogram showed paroxysmal AF; echocardiography revealed mild left atrial enlargement without structural heart disease. Symptoms worsened during the recovery phase after runs, suggesting vagally mediated AF. After unsuccessful flecainide therapy, he underwent pulmonary vein isolation. Twelve months later, he remained free of recurrent AF on Holter monitoring and successfully resumed endurance training following an 8-week recovery period. …

Recurrent Pubic Osteomyelitis And Urosymphyseal Fistula In A Prostate Cancer Survivor: A Multidisciplinary Management Challenge, Peng Jhen Wu, Navin Sampathkumar, Tanmay Singh, Sonal Gandhi

Journal of Community Hospital Internal Medicine Perspectives

A 67-year-old male with a history of prostate cancer, treated with prostatectomy and subsequent radiation for recurrence, presented with a complex clinical course of recurrent osteomyelitis and a persistent urosymphyseal fistula with associated phlegmon. Following stereotactic body radiation therapy (SBRT) for a T4 vertebral lesion, he developed pelvic osteomyelitis, from which Kocuria species was cultured. The progression of his disease led to a urosymphyseal fistula, necessitating a cystectomy with ileal conduit and pubic bone debridement. Despite this extensive surgical intervention, he presented one year later with recurrent ileal conduit phlegmon and osteomyelitis. This case highlights the significant diagnostic and management …

Infectious Aortitis Secondary To Gastrointestinal Pathogens: A Case Series And Syndromic Review, Natasa Kostic, Ilana Goldberg, Devin Weber

Division of Internal Medicine Faculty Papers & Presentations

Aortitis is a rare but serious complication of infection that results in high morbidity and mortality. The most common location is in preexisting aneurysmal disease in a patient with multiple chronic comorbidities. The pathogens often reflect gastrointestinal bacteria, the classic example being Salmonella spp., but also include other enteric flora, Staphylococcus aureus, Streptococcus spp., and more. Herein, we describe 2 cases of aortitis caused by gastrointestinal bacteria and review management of this complex syndrome.

Defining A Multi-Omic, Ai-Enabled Stool Screening Paradigm For Colorectal Cancer: A Consensus Framework For Clinical Translation, Arturo Loaiza-Bonilla, Yan Leyfman, Viviana Cortiana, Rhys Crawford, Shivani Modi

Einstein Health Papers

Colorectal cancer (CRC) develops through both conventional adenoma-carcinoma and serrated neoplasia pathways, yet noninvasive screening still under-detects the advanced precursor lesions that enable true cancer prevention. Stool-based screening reduces CRC mortality, but its preventive impact remains constrained by limited detection of advanced precancerous lesions (APLs), including advanced adenomas and sessile serrated lesions. Next-generation multitarget stool DNA assays (mt-sDNA; e.g., Cologuard Plus) have established high sensitivity for CRC and specificity approaching 94%, leaving improved APL detection as the principal opportunity for innovation. This review presents a consensus framework for a multi-omic stool screening paradigm that integrates host epigenetic markers (DNA methylation) …

Optimizing Electrode Placement And Information Capacity For Local Field Potentials In Cortex, Jace A Willis, Christopher E Wright, Ruoqian Zhu, Yilan Ruan, Joshua Stallings, Amada M Abrego, Takfarinas Medani, Promit Moitra, Arjun Ramakrishnan, Charles E Schroeder, Anand A Joshi, Nitin Tandon, Richard M Leahy, John C Mosher, John P Seymour

Recent neurosurgery advancements include improved stereotactic targeting and increased density and specificity of electrophysiological evaluation. This study introduces a subject-specific, in silico modeling tool for optimizing electrode placement and maximizing coverage with a variety of devices. The basis for optimization is the Shannon-Hartley information capacity of field potentials derived from dipolar sources. The approach integrates subject-specific MRI data with finite element modeling (FEM) used to simulate the sensitivity of subdural and intracortical devices. Sensitivity maps, or lead fields, from these models enable the comparison of different electrode placements, contact sizes, contact configurations, and substrate properties, which are often overlooked factors. …

A Rare And Challenging Polymicrobial Pleural Infection Involving Cupriavidus Pauculus In A Patient With Rheumatoid Arthritis And Multiple Complications, Moiz Ahmed Khan, Syeda Samiya Kamal, Muhammad Muneeb, Summaya Zafar

The University of Louisville Journal of Respiratory Infections

A 58-year-old female with a 15-year history of rheumatoid arthritis (RA) and a history of treatment consisting of methotrexate, hydroxychloroquine, leflunomide, and chronic prednisolone therapy, presented with fever, productive cough, dyspnea, and left leg cellulitis. She developed septic shock complicated by tension pneumothorax requiring emergency thoracostomy and non-ST-elevation myocardial infarction (NSTEMI). Pleural fluid culture grew Cupriavidus pauculus, a rare environmental gram-negative bacillus, alongside Burkholderia cepacia and Candida parapsilosis, indicating polymicrobial infection which was most likely predisposed by patient's immunosuppressed state from RA and prolonged steroid use. Treatment consisted of trimethoprim/sulfamethoxazole, meropenem, fluconazole, and cardiopulmonary support, and culminated in …
