Global, regional, and national age-sex-specific burden of diarrhoeal diseases, their risk factors, and aetiologies, 1990-2021, for 204 countries and territories: a systematic analysis for the Global Burden of Disease Study 2021.

Background: Diarrhoeal diseases claim more than 1 million lives annually and are a leading cause of death in children younger than 5 years. Comprehensive global estimates of the diarrhoeal disease burden for specific age groups of children younger than 5 years are scarce, and the burden in children older than 5 years and in adults is also understudied. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2021 to assess the burden of, and trends in, diarrhoeal diseases overall and attributable to 13 pathogens, as well as the contributions of associated risk factors, in children and adults in 204 countries and territories from 1990 to 2021.

Inflammation switches the chemoattractant requirements for naive lymphocyte entry into lymph nodes.

Sustained lymphocyte migration from blood into lymph nodes (LNs) is important for immune responses. The CC-chemokine receptor-7 (CCR7) ligand CCL21 is required for LN entry but is downregulated during inflammation, and it has been unclear how recruitment is maintained. Here, we show that the oxysterol biosynthetic enzyme cholesterol-25-hydroxylase (Ch25h) is upregulated in LN high endothelial venules during viral infection.

Role of microRNAs in immunoregulatory functions of epithelial cells.

Epithelial cells (ECs) provide the first line of defense against microbial threats and environmental challenges. They participate in the host's immune responses via the expression and secretion of various immune-related molecules such as cytokines and chemokines, as well as interaction with immune cells. A growing body of evidence suggests that the dysregulated function of ECs can be involved in the pathophysiology of a broad range of infectious, autoimmune, and inflammatory diseases, including inflammatory bowel disease (IBD), asthma, multiple sclerosis, and rheumatoid arthritis.

HYPERVIRULENT KLEBSIELLA PNEUMONIAE OSTEOMYELITIS IN A CHILD.

An 18-month-old boy presented with septic arthritis and osteomyelitis caused by Hypervirulent Klebsiella pneumoniae harboring cardinal virulence genes. The condition necessitated several surgical interventions, and a prolonged course of antibiotic therapy to effectively manage the severe infection and prevent complications, highlighting the challenges posed by Hypervirulent Klebsiella pneumoniae in pediatric cases.

First case report of septic arthritis associated with an indwelling device.

usually presents with erythrasma, a macular rash, but rarely it can cause extracutaneous infections such as endocarditis, peritonitis, pyelonephritis, and catheter-related bloodstream infections. Here, we present the first case of septic arthritis caused by and a literature review of invasive infections. The diagnosis was confirmed by the patient's clinical findings and microbiological examination of the joint fluid.

SARS-CoV-2 ORF8 drives osteoclastogenesis in preexisting immune-mediated inflammatory diseases.

Patients with immune-mediated inflammatory diseases (IMIDs) like rheumatoid arthritis (RA) are at higher risk for severe COVID-19 and long-term complications in bone health. Emerging clinical evidence demonstrated that SARS-CoV-2 infection reduces bone turnover and promotes bone loss, but the mechanism underlying worsened bone health remains elusive. This study sought to identify specific immune mediators that exacerbated preexisting IMIDs after SARS-CoV-2 exposure.

Correlation Between Pain, Disease Activity, and Rheumatoid Factor Positivity in Patients with Chikungunya Arthritis.

Chikungunya fever (CHIKF) is an acute viral disease caused by the chikungunya virus (CHIKV) transmitted by mosquitoes. The acute phase presents with limited symptoms and low mortality, but approximately half of cases progress to more chronic illness with persistent and disabling joint symptoms. To better characterize the burden of chronic disease, we analyzed the relationship between pain intensity, the Disease Activity Index by DAS28-ESR, rheumatoid factor (RF) positivity, sex, and age in a retrospective cohort of 133 patients with chikungunya arthritis (CHIKA).

Investigating the link between Helicobacter pylori infection and psoriatic disease: an immunological study.

Helicobacter pylori (Hp) has been postulated as an infectious trigger of psoriatic disease, namely psoriasis (Ps) and psoriatic arthritis (PsA), but meticulous antibody (ab) reactivity against all dominant and subdominant Hp antigens in demographically matched PsA and Ps patients and healthy controls has not been performed so far. IgG anti-Hp ab testing was performed by combining immunoblotting and line assays in 263 serum samples from 89 patients with PsA, 114 patients with Ps, and 60 demographically matched healthy controls (HCs). Anti-Hp positivity did not differ between PsA, Ps, and HCs (P > 0.

KLF2 controls the apoptosis of neutrophils and is associated with disease activity of systemic lupus erythematosus.

Background: Neutropenia is more common in patients with systemic lupus erythematosus (SLE) and is a major cause of life-threatening infections. The increased apoptosis of neutrophils is likely to be an essential cause of neutropenia in SLE. However, the detailed mechanisms of increased neutrophil apoptosis in SLE remain unknown.

Gout: global epidemiology, risk factors, comorbidities and complications: a narrative review.

Background: Gout is one of the oldest known diseases and the most common form of inflammatory arthritis. The established risk factors for gout include hyperuricemia, chronic renal disease, genetic, alcohol consumption, dietary factors, diuretic use, hypertension, obesity, and metabolic syndrome. Patients with gout have an increased risk of all-cause mortality, particularly from cardiovascular disease, cancer, and infectious diseases.

Resident synovial macrophages in synovial fluid: Implications for immunoregulation.

Resident synovial macrophages (RSMs) are anti-inflammatory, self-renewing macrophages that provide physical immune sequestration of the joint space from the peripheral immune system. Increased permeability of this structure is associated with peripheral immune cells in the synovial fluid (SF). Direct measures of synovial barrier integrity are possible with tissue histology, but after barrier breakdown, if these cells perpetuate or initiate chronic inflammation in SF remains unknown.

The alphavirus determinants of intercellular long extension formation.

The alphavirus chikungunya virus (CHIKV) is a serious human pathogen that can cause large-scale epidemics characterized by fever and joint pain and often resulting in chronic arthritis. Infection by alphaviruses including CHIKV and the closely related Semliki Forest virus (SFV) can induce the formation of filopodia-like intercellular long extensions (ILEs). ILEs emanate from an infected cell, stably attach to a neighboring cell, and mediate cell-to-cell viral transmission that is resistant to neutralizing antibodies.

Clinical indicators for distinguishing septic arthritis from paediatric transient synovitis of the hip: a systematic review and meta-analysis.

Background: Septic arthritis (SA) of the hip joint is a serious infection that can result in irreversible complications. Distinguishing septic arthritis from transient synovitis, the most common cause of hip pain in children, is crucial for preventing severe outcomes. Existing research has primarily focused on identifying clinical signs and laboratory findings that indicate high-risk patients who may need invasive diagnostic procedures; however, results have been inconsistent.

Exploring microRNA signatures in pediatric non-infectious uveitis: meta-analysis and molecular profiling of patient samples.

To find a distinct non-coding RNA characteristic for idiopathic uveitis in the pediatric population. To explore the autoimmune-related miRNA expression profile in pediatric patients with idiopathic uveitis (IU) and juvenile idiopathic arthritis-associated uveitis (JIA-AU) and find a common molecular background for idiopathic uveitis and other autoimmune diseases. The expression levels of miRNAs were analyzed by quantitative real-time PCR using serum samples from patients with idiopathic uveitis (n = 8), juvenile idiopathic arthritis-associated uveitis (n = 7), and healthy controls.

Minocycline-induced lupus.

Antibiotics are indicated for inappropriately prolonged durations not only for infectious diseases but also for non-infectious dermatologic conditions such as acne vulgaris, but inappropriate use is not uncommon. Inappropriate antibiotic prescription can contribute to the emergence of multidrug-resistant organisms, patient harm such as adverse drug events and increased healthcare costs. We experienced a case involving a late adolescent with acne vulgaris who had been treated with minocycline for more than 2 years, leading to the development of drug-induced lupus, attributed to minocycline.

Diagnostic value of serum markers and C-reactive protein of joint fluid in purulent arthritis.

Introduction: Predicting purulent arthritis with a single marker may result in low sensitivity and specificity. We investigated the diagnostic value of serum markers and joint fluid C-reactive protein (CRP) in purulent arthritis.

Methodology: A total of 183 patients with acute joint infection, who were treated at our hospital between April 2019 and September 2022, were retrospectively analyzed via convenient sampling.

Herpes Simplex Virus 1 Infection of Human Brain Organoids and Pancreatic Stem Cell-Islets Drives Organoid-Specific Transcripts Associated with Alzheimer's Disease and Autoimmune Diseases.

Viral infections leading to inflammation have been implicated in several common diseases, such as Alzheimer's disease (AD) and type 1 diabetes (T1D). Of note, herpes simplex virus 1 (HSV-1) has been reported to be associated with AD. We sought to identify the transcriptomic changes due to HSV-1 infection and anti-viral drug (acyclovir, ACV) treatment of HSV-1 infection in dissociated cells from human cerebral organoids (dcOrgs) versus stem cell-derived pancreatic islets (sc-islets) to gain potential biological insights into the relevance of HSV-1-induced inflammation in AD and T1D.

Population Pharmacokinetics of Meropenem Across the Adult Lifespan.

Background And Objective: We conducted an opportunistic pharmacokinetic study to evaluate the population pharmacokinetics of meropenem, an antimicrobial commonly used to treat Gram-negative infections in adults of different ages, including older adults, and determined optimal dosing regimens.

Methods: A total of 99 patients were included. The population pharmacokinetic models used had two compartments: zero-order input and linear elimination.

THE EFFECTS OF RAIN AND DROUGHT ON INCIDENCE OF ENTERIC DISEASE IN PENNSYLVANIA (2010 - 2019).

Background: Campylobacter, nontyphoidal Salmonella, Cryptosporidium, and Giardia cause an estimated 1 million cases of domestically acquired waterborne diseases annually in the United States. Acute symptoms can include diarrhea and vomiting; however, these illnesses can result in longer term complications such as reactive arthritis, Guillan Barré syndrome and death, particularly in immunocompromised individuals. Precipitation and drought can plausibly increase the risk of enteric infections, but consensus in the literature is lacking.

Pain in chronic liver disease compared to other chronic conditions: Results from a contemporary nationally representative cohort study.

Background: Pain is common in patients with chronic liver disease. Our limited understanding of patterns and severity of pain in this population hinders the development of effective cirrhosis-specific pain management strategies.

Methods: Using cross-sectional data from the 2016-2021 National Health Interview Survey, we examined rates, severity, and functional limitations due to pain in respondents with liver disease (viral hepatitis, cirrhosis, and liver cancer), compared to the general population and those with other chronic conditions associated with pain (ie, arthritis, diabetes, and chronic kidney disease).

Exploring the Function of OPTN From Multiple Dimensions.

Autophagy is an essential intracellular degradation system responsible for delivering cytoplasmic components to lysosomes. Within this intricate process, optineurin (OPTN), an autophagy receptor, has attracted extensive attention due to its multifaceted roles in the autophagy process. OPTN is regulated by various posttranslational modifications and actively participates in numerous signaling pathways and cellular processes.

Fusobacterium necrophorum septic arthritis of the hip: a case-report and literature review.

Introduction: Fusobacterium necrophorum is a rare but significant cause of septic arthritis, typically following oropharyngeal infections in adolescents. This anaerobic pathogen, commonly associated with Lemierre's syndrome, can lead to joint infections, posing risks for severe morbidity if diagnosis and treatment are delayed. Awareness and timely intervention are essential for preventing long-term joint damage.

Splice site and de novo variants can cause PLCG2-associated immune dysregulation with cold urticaria (PLAID-CU).

Background: Phospholipase Cγ2 (PLCγ2) is an important signaling molecule that receives and transmits signals from various cell surface receptors in most hematopoietic lineages. Variants of PLCG2 cause PLCγ2-associated immune dysregulation (PLAID), a family of conditions that are classified by mutational effect. PLAID with cold urticaria (PLAID-CU) is caused by in-frame deletions of PLCG2 that are dominant negative at physiologic temperatures but become spontaneously active at sub-physiologic temperatures.
