Infections review

Rift Valley fever virus (RVFV) is a mosquito-borne virus endemic to Africa and the Middle East. RVFV infection can cause encephalitis, which is associated with significant morbidity and mortality. Studies of RVFV encephalitis following percutaneous inoculation, as would occur following a mosquito bite, have historically been limited by a lack of consistent animal models. In this review, we describe new insights into the pathogenesis of RVFV and the opportunities provided by new mouse models. We underscore the need to consider viral strain and route of inoculation when interpreting data obtained using animal models...

Nontraumatic pathologic conditions of the craniovertebral junction encompass a range of conditions affecting the complex anatomy of this region without direct physical injury. These conditions include congenital syndromes that predispose individuals to ligamentous laxity, potentially leading to instability. Additionally, rare but noteworthy cases such as Grisel syndrome, a cause of pediatric torticollis, may arise without a traumatic trigger. Inflammatory diseases, including rheumatoid arthritis, ankylosing spondylitis, and crystal deposition, can lead to cervical instability and spinal cord compression...

Vascular graft infection (VGI) is one of the most serious complications following arterial reconstructive surgery. VGI has received increasing attention over the past decade, but many questions remain regarding its diagnosis and management. In this review, we describe our approach to VGI through multidisciplinary collaboration and discuss decision-making for challenging presentations. This document will concentrate on VGI that impacts both aneurysms and pseudoaneurysms excluding the ascending thoracic aorta...

Respiratory illnesses and its repercussions are becoming more prevalent worldwide. It is necessary to research both innovative treatment and preventative techniques. Millions of confirmed cases and fatalities from the COVID-19 epidemic occurred over the previous two years. According to the review research, cannabinoids are a class of medicines that should be considered for the treatment of respiratory conditions. Cannabinoids and inhibitors of endocannabinoid degradation have illustrated advantageous anti-inflammatory, asthma, pulmonary fibrosis, and pulmonary artery hypotension in numerous studies ( in vitro and in vivo )...

BACKGROUND: Hodgkin lymphoma (HL) occurs at young ages, with the highest incidence between 20 and 40 years. While cure rates have improved to 80%-90% over the past decades, survivors of HL are at substantial risk of late treatment-related complications, such as cardiovascular diseases, breast cancer, severe infections, and hypothyroidism. To reduce morbidity and mortality from late treatment effects, the Dutch Better care after lymphoma, Evaluation of long-term Treatment Effects and screening Recommendations (BETER) consortium developed a survivorship care program for 5-year survivors of HL that includes risk-based screening for and treatment of (risk factors for) late adverse events...

INTRODUCTION: In adults, sodium-glucose cotransporter type 2 inhibitors have revolutionised the treatment of type 2 diabetes mellitus, heart failure, and chronic kidney disease. OBJECTIVE: We aimed to review information on compassionate use, clinical pharmacology, efficacy, and safety of dapagliflozin and empagliflozin in children. METHODS: We conducted a systematic review of published clinical trials, case reports, and observational studies in Medline, Excerpta Medica, and Web of Science databases from inception to September 2023...

The increasing frequency of total hip (THA) and knee arthroplasties (TKA) is marred by the rise in periprosthetic joint infections (PJIs) and surgical site infections (SSIs), with PJIs incurring costs over $1.62 billion as of 2020 and individual case management averaging $90,000. SSIs additionally burden the U.S. healthcare economy with billions in expenses annually. PJI prevalence in primary THA and TKA ranges from 0.5% to 2.4%, spiking to 20% in revisions and representing 25% of TKA revision causes. Projections estimate up to 270,000 annual PJI cases by 2030...

BACKGROUND: Linagliptin is an oral dipeptidyl peptidase DPP-4 inhibitor, which is indicated for the treatment of Type 2 diabetes mellitus (T2DM) as monotherapy or add-on to therapy with other hypoglycemic drugs. OBJECTIVES: We aimed to summarize the evidence from randomized controlled trials (RCTs) to assess the safety of linagliptin focusing on cardiovascular risks among subjects with type 2 diabetes mellitus. METHODS: We conducted a systematic search across the following databases: Medline, Embase, the Cochrane Central Register of Controlled Trials and ClinicalTrials...

BACKGROUND: A complete review of the development of neonatology in the last 40 years would probably require a compendium with several volumes, to bring to view the remarkable improvements in survival rates and neurodevelopmental outcomes of ill babies in Austria, most industrial countries and to some extent worldwide. The challenge I had to solve here was to integrate my own contributions to the field of neonatology during this period and particularly the contributions of my team from the Division of Neonatology and Pediatric Intensive Care Medicine, Department of Pediatrics and Adolescence Medicine, Medical University Vienna where I was working first as an intern and resident and later had the privilege to become head of department...

Bronchopulmonary dysplasia (BPD) is the most common serious complication of very preterm infants (VPI) or very low birth weight (VLBW) infants. Studies implicate viral infections in etiopathogenesis. The aim of this study was to summarize the relationship between viral infections and BPD through a systematic review and meta-analysis. We searched PubMed, Embase, the Web of Science Core Collection, and the Cochrane Database on December 19, 2023. We included observational studies that examined the association between viral infections and BPD in preterm infants...

PURPOSE: High-energy injuries to the knee may lead to extensive soft tissue loss, fractures, and potential loss of extensor function. The gastrocnemius flap is a prominent reconstructive option for patients with injuries involving the knee and proximal third of the lower extremity. To the best of our knowledge, there has not been an informative review that has evaluated outcomes of patients who have undergone post-traumatic knee reconstruction with a pedicled medial or lateral gastrocnemius flap...

Currently, there is no universally accepted, standardized protocol for pre-operative antibiotic administration in the setting of appendectomy for complicated appendicitis among pediatric patients. Strategies to mitigate surgical site infections (SSIs) must be balanced with optimal antibiotic use and exposure. We conducted a retrospective chart review to compare outcomes between patients treated pre-operatively with a single pre-operative dose of antibiotics with those who received additional antibiotics prior to laparoscopic appendectomy for complicated appendicitis between 2020 and 2022...

BACKGROUND: Microorganisms colonizing the apical root canal system are conceivably the ones directly involved with the causation and maintenance of apical periodontitis. OBJECTIVES: This article systematically reviews the reports on the microbiome occurring exclusively at the apical root canal of teeth with primary and posttreatment apical periodontitis. METHODS: The electronic databases PubMed, Embase, Web of Science, Science Direct, and Proquest were searched up to August 2023...

Background: Candida species account for approximately 15% of hospital-associated infections, causing fatal consequences, especially in critically ill patients. This study aimed to evaluate invasive candidiasis (IC) risk factors in critically ill patients undergoing surgery. Patients and Methods: We retrospectively reviewed the medical records of 583 patients who underwent emergency surgery for complicated intra-abdominal infections between January 2016 and December 2021. Patients were divided into two groups according to the presence or absence of IC during their hospital stay...

Epstein-Barr Virus (EBV), a dsDNA herpesvirus, is believed to play a significant role in exacerbating and potentially triggering autoimmune and autoinflammatory maladies. Around 90% of the world is infected with the virus, which establishes latency within lymphocytes. EBV is also known to cause infectious mononucleosis, a self-limited flu-like illness, in adolescents. EBV is often reactivated and it employs several mechanisms of evading the host immune system. It has also been implicated in inducing host immune dysfunction potentially resulting in exacerbation or triggering of inflammatory processes...

UNLABELLED: Identifying long-term care facility (LTCF)-exposed inpatients is important for infection control research and practice, but ascertaining LTCF exposure is challenging. Across a large validation study, electronic health record data fields identified 76% of LTCF-exposed patients compared to manual chart review. OBJECTIVE: Residence or recent stay in a long-term care facility (LTCF) is an important risk factor for antibiotic-resistant bacterial colonization...

Malaria is a global health problem that causes 1.5-2.7 million deaths worldwide each year. Resistance to antimalarial drugs in malaria parasites and to insecticides in vectors is one of the most serious issues in the fight against the disease. Moreover, the lack of an effective vaccine against malaria is still a major concern. Recent developments in nanotechnology have resulted in new prospects for the fight against malaria, especially by obtaining metal nanoparticles (NPs) that are less toxic, highly biocompatible, environmentally friendly, and less expensive...

Pathogenic microorganisms produce numerous metabolites, including volatile organic compounds (VOCs). Monitoring these metabolites in biological matrices (e.g., urine, blood, or breath) can reveal the presence of specific microorganisms, enabling the early diagnosis of infections and the timely implementation of targeted therapy. However, complex matrices only contain trace levels of VOCs, and their constituent components can hinder determination of these compounds. Therefore, modern analytical techniques enabling the non-invasive identification and precise quantification of microbial VOCs are needed...
