Purpose of review To review role of artificial intelligence in medicine. Recent findings Artificial intelligence is continuing to revolutionize access, diagnosis, personalization of medicine, and treatment in healthcare. As a matter of fact, artificial intelligence contributed to the research that resulted in 2024 Nobel Prizes in physics, chemistry, and economics. We are only at the tip of the iceberg in utilizing the abilities of artificial intelligence in medicine to improve accuracy of diagnoses and to enhance patient outcomes. Artificial intelligence has allowed better image analysis, prediction of progression of disease, personalized treatment plans, incorporations of genomics, and improved efficiency in care and follow-up utilizing home monitoring. In ocular health diagnosis and treatment of diabetic retinopathy, macular degeneration, glaucoma, corneal infections, and ectasia are only a few examples of how the power of artificial intelligence has been harnessed. Even though there are still challenges that need more work in the areas of patient privacy, Health Insurance Portability and Accountability Act (HIPAA) compliance, reliability, and development of regulatory frameworks, artificial intelligence has revolutionized and will continue to revolutionize medicine. Summary Artificial intelligence is enhancing medical diagnosis and treatment, as well as access and prevention. Ocular imaging, visual outcome, optics, intraocular pressure, and data points will continue to see growth it the field of artificial intelligence.

Background: Culture-negative vertebral osteomyelitis presents a significant diagnostic challenge. Neisseria sicca (N. sicca) is a typically benign commensal organism of the upper respiratory tract that rarely causes invasive infections, warranting cautious interpretation if isolated in a single positive culture. This case study details a 62-year-old male diagnosed with vertebral osteomyelitis caused by N. sicca, examining diagnostic challenges, treatment, and outcomes. Methods: We conducted a comprehensive search on MEDLINE using the keywords “Neisseria sicca”, “osteomyelitis”, and “diskitis”. An additional search excluding N. gonorrhea and N. meningitidis was also performed, revealing a total of four cases of N. sicca osteomyelitis in the literature. Results: A 62-year-old male with a history of hypertension, type 2 diabetes, atrial fibrillation, and previous L5-S1 spinal fusion presented with fever and back pain in May 2023. Initial imaging revealed T8-T9 vertebral osteomyelitis. Despite a six-week course of IV daptomycin, his symptoms worsened, prompting further evaluation. A CT-guided biopsy with comprehensive testing, including histopathology and microbial cultures, initially identified N. sicca. Due to its rarity, additional biopsies were conducted, confirming the infection. IV ceftriaxone was initiated, leading to significant pain improvement, and a subsequent MRI showed near resolution. The patient transitioned to oral cefuroxime, with follow-up confirming complete infection resolution by December 2023. Conclusions: This case underscores the importance of a structured diagnostic approach in culture-negative vertebral osteomyelitis to differentiate between commensal contamination and true infection. Repeated positive cultures of N. sicca from a sterile site confirmed its role as the causative agent. Early identification and targeted antibiotic therapy are critical to improving outcomes in rare cases of N. sicca vertebral osteomyelitis.

Abstract Background The recognition of autoimmune causes of encephalitis has led to epidemiological shifts in the worldwide characteristics of encephalitis. N-methyl-D-aspartate receptor (NMDAR) antibody encephalitis leads to well-established complex neuropsychiatric manifestations. In low- and middle-income countries, including Vietnam, its relative incidence, especially in children, is unknown and most neurologists currently consider infectious encephalitis prior to autoimmune etiologies. Methods The study was prospectively conducted at Children's Hospital 1 in Ho Chi Minh City between March 2020 and December 2022. Any child admitted to the Department of Infectious Diseases and Neurology fulfilling the case definition of encephalitis was eligible to participate. Cerebrospinal fluid samples were collected alongside meta-clinical data for analysis. Results We recruited 164 children with a clinical diagnosis of encephalitis. Etiologies were determined as NMDAR antibody encephalitis in 23 of 164 cases (14.0%), Japanese encephalitis virus in 14 of 164 (8.5%), and herpes simplex virus in 4 of 164 (2.4%). Clinical categorizations suggested idiopathic viral encephalitis in another 71 (43.3%), and autoimmune encephalitis of unknown origin in the remaining 52. Factors including demographics, specific clinical features, cerebrospinal fluid and electroencephalogram findings, and length of hospital stay were significantly different between NMDAR antibody encephalitis and Japanese encephalitis. Conclusions At a tertiary children's hospital in Vietnam, the prevalence of NMDAR antibody encephalitis exceeds that of Japanese encephalitis, the most common infectious encephalitis cause in Southeast Asia. NMDAR antibody encephalitis is associated with long hospital stay and poor outcomes. These findings should change pediatric diagnostics, to earlier consider autoimmune treatments in this clinical setting.

ABSTRACTBackgroundCoccidioidomycosis is a fungal infection that poses a serious risk when transmitted through organ transplantation. We analyzed cases reported to the Organ Procurement and Transplantation Network ad hoc Disease Transmission Advisory Committee from 2013 to 2022.MethodsDonors and/or recipients who had positive Coccidioides immitis/posadasii serology, pathology, and/or culture were included in this study. Cases adjudicated as ‘proven’ or ‘probable’ were analyzed for donor infection risk factors, the timing of infection, transmission by organ type, clinical manifestations, and recipient outcomes. Patient and facility identifiers were removed prior to review.ResultsDuring this time period, 73 potential instances of Coccidioides donor disease transmission events were reported. Among them, infection was transmitted from seven deceased donors to eight recipients. All seven deceased donors had prior infection or exposure to regions where coccidioidomycosis is endemic. Of 20 individuals receiving organs from these donors, eight developed infection, resulting in a 40% transmission rate. The median time to diagnosis post‐transplant was 39 days. Disseminated disease occurred in six recipients, five of whom died from the infection. Notably, none of the recipients who received prophylactic antifungal treatment died from the infection.ConclusionDespite its rarity, donor‐derived Coccidioides infection is a serious concern, particularly due to the high mortality rate in the early post‐transplant period. To mitigate these risks, a thorough assessment of donor exposure history, coupled with donor serology and bronchoalveolar lavage cultures, can effectively guide post‐transplant antifungal prophylaxis. Prompt reporting is crucial to prevent Coccidioides infections among other recipients. image

The field of ribonucleic acid (RNA) biology has revealed an array of noncoding RNA species, particularly long noncoding RNAs (lncRNAs), which play crucial roles in liver disease pathogenesis. This review explores the diverse functions of lncRNAs in liver pathology, including metabolic-associated steatotic liver disease, hepatocellular carcinoma, alcohol-related liver disease, and cholangiopathies such as primary sclerosing cholangitis and cholangiocarcinoma. We highlight key lncRNAs that regulate lipid metabolism, inflammation, fibrosis, and oncogenesis in the liver, demonstrating their diagnostic and therapeutic potential. Emerging RNA-based therapies, such as mRNA therapy, RNA interference, and antisense oligonucleotides, offer approaches to modulate lncRNA activity and address liver disease at a molecular level. Advances in sequencing technologies and bioinformatics pipelines are simultaneously enabling the identification and functional characterization of novel lncRNAs, driving innovation in personalized medicine. In conclusion, this review highlights the potential of lncRNAs as biomarkers and therapeutic targets in liver disease and emphasizes the need for further research into their regulatory mechanisms and clinical applications.

Abstract Background and Aims Active inflammatory bowel disease (IBD) at conception is associated with adverse pregnancy outcomes. International guidelines address antenatal care, but contraception counseling and risk assessment are not addressed. Data on healthcare professionals’ guidance for women with IBD regarding contraception are scarce. We aimed to describe contraceptive use, preferences, knowledge, and barriers among women with IBD. Methods A 34-item questionnaire was administered to female IBD patients aged 18-45. Disease control was measured using PRO-2 and IBD-control questionnaire, and contraceptive preferences were assessed by the contraceptive features survey. Logistic regression explored associations between contraceptive use, attitudes, disease remission status, and other factors. Results Of 338 women surveyed, 243 (74%) used some form of contraception. Oral birth control pills (28%) and barrier methods (18%) were most used but 20% used long-acting methods. Women with active disease were more likely to use long-acting contraception (23%) compared to those in remission (17%). Contraceptive priorities were effectiveness (78%), ease of use (75%), and minimal side effects (68%). Only 25% women had discussed reproductive issues with their IBD clinician, though 85% were comfortable to do so. Preferred sources for reproductive counseling were IBD nurses (79%), general practitioners (75%), IBD doctors (68%), and gynecologists (49%). Conclusions A quarter of women with IBD were not using any contraception, and long-acting contraceptive use was low. Women prefer effective, easy-to-use contraceptives with minimal side effects but lack knowledge on effective contraception-related issues. Better education and proactive discussions between healthcare providers and patients could improve reproductive health in women with IBD.

Abstract Aims Excessive alcohol use is associated with an increased risk of cognitive impairment. Since increased amyloid plaque burden exacerbates cognitive decline, we sought to assess the potential impact of alcohol use disorder (AUD) on cognition, memory, and amyloid burden corresponding with age. Methods We conducted the retrospective analysis with 6036 subjects, including 269 AUD+ subjects. A four-item CAGE (C—Cutting Down, A—Annoyance by Criticism, G—Guilty Feeling, E—Eye-openers) alcohol questionnaire was given during the recruitment to determine AUD in each participant. We assessed cognitive function, focusing on memory using neuropsychological testing. For 1038 participants, including 57 AUD+ subjects, we measured amyloid burden using the 11C Pittsburgh Compound B tracer-based positron emission tomography imaging. Results AUD+ was significantly associated with lower scores of cognition and memory function relative to AUD− individuals. No significant association was found with AUD and elevated brain amyloid under the age of 65. However, further analysis showed that those aged ≥65 showed greater odds for abnormal amyloid in AUD+ compared to AUD− participants. Conclusions Our results underscore AUD as a risk factor for cognitive decline and diminished memory, particularly in aging populations. The role of AUD in brain amyloid accumulation requires further study.
