Ih

PURPOSE OF REVIEW: Ischemic hepatitis (IH) refers to diffuse liver injury secondary to hypoperfusion. The condition is usually seen in the critical care setting and is associated with significant mortality. IH typically occurs in the setting of systemic hypotension superimposed on some form of underlying cardiac dysfunction. This review aims to report what is known and what is new about the etiology, pathophysiology, and clinical features associated with IH. RECENT FINDINGS: In recent years, studies on IH have largely confirmed earlier reports regarding etiologies, comorbid conditions, and associated mortality...

INTRODUCTION: Excessive daytime sleepiness (EDS) is a crucial symptom that diminishes the quality of life. The primary causes of EDS are central hypersomnia, including narcolepsy type 1 (NT1), type 2 (NT2), and idiopathic hypersomnia (IH). EDS is often associated with other psychiatric disorders, particularly attention deficit hyperactivity disorder (ADHD). The Multiple Sleep Latency Test (MSLT) is the standard assessment tool for EDS. Although the MSLT yields numerous parameters, most are not employed in clinical practice...

This study explored the optimum immunization schedule for the quadrivalent influenza split-virion vaccine containing influenza A strains (H1N1 and H3N2) and B lineage strains (Yamagata and Victoria) in children aged 3-8 years. The 652 participants enrolled were divided into two groups based on a history of influenza immunization (IH group) or no history of influenza immunization (NH group). The groups were administered a two-dose immunization schedule on days 0 and 30. In the NH group, on day 30 after the first dose, the positive rates of influenza hemagglutination-inhibition antibodies of strains H1N1, H3N2, BV, and BY were 85...

Notch ligands and receptors are important for cell specification and angiogenesis, but their role in oxygen-induced retinopathy (OIR) is not well studied. Delta-like ligand (DLL)-4/Notch inhibits angiogenesis, while Jagged-1/Notch promotes angiogenesis. We tested the hypothesis that early supplementation with antioxidants and/or fish oil curtails severe OIR by inducing DLL-4/Notch and reducing Jagged-1/Notch. Newborn rats were exposed to brief intermittent hypoxia (IH) during hyperoxia, during which they received daily oral supplements of (1) fish oil, (2) coenzyme Q10 (CoQ10) in olive oil (OO), (3) glutathione nanoparticles (nGSH), (4) fish oil + CoQ10, or (5) OO (controls) from birth (P0) to P14...

BACKGROUND: To facilitate robotic radical prostatectomy (RP), we developed a novel anterior approach that utilizes a peritoneal incision between the umbilical ligaments to develop the Retzius space without contacting the internal inguinal rings, followed by closure of this space prior to prostatectomy and vesicourethral anastomosis. This approach could decrease the incidence of postoperative inguinal hernia (IH), similar to a Retzius-sparing RP (RS-RP). We compared the incidence of IH following this novel approach with that following conventional anterior RP and RS-RP...

PURPOSE: Metachronous contralateral inguinal hernia (MCIH) may occur after unilateral inguinal hernia (IH) repair, potentially as a result of occult IH (OIH). Contralateral OIH can be checked for during laparoscopic transabdominal hernioplasty for the treatment of unilateral IH. This study aims to assess the efficacy of laparoscopic iliopubic tract repair (IPTR) in treating contralateral OIH to reduce MCIH. METHODS: The medical charts of 3165 patients aged > 18 years who underwent laparoscopic transabdominal hernioplasty for unilateral IH from January 2013 to December 2021 were retrospectively reviewed...

The literature study was conducted by using the Web of Science (WoS) database, employing bibliometric analysis to examine all papers released from 1980 to 2020. The search was performed using the terms "sepsis, septicemia, septic shock" specifically within the titles of the publications. The findings of the literature research revealed a total of 51,725 articles. Out of the total number of publications, 26,896 articles were identified, accounting for 51.9% of the total. The bibliometric study revealed that the United States had the largest number of papers (8693), followed by China (2807), Germany (2299), France (1606), and the United Kingdom (1932)...

In this study, the electrophysiological and biochemical consequences of repeated exposure to morphine in male rats on glutamatergic synaptic transmission, synaptic plasticity, the expression of GABA receptors and glutamate receptors at the temporoammonic-CA1 synapse along the longitudinal axis of the hippocampus (dorsal, intermediate, ventral, DH, IH, VH, respectively) were investigated. Slice electrophysiological methods, qRT-PCR, and western blotting techniques were used to characterize synaptic plasticity properties...

BACKGROUND: Unstable cerebral hemodynamics places preterm infants at high risk of brain injury. We adapted an innovative, fiber-free, wearable diffuse speckle contrast flow-oximetry (DSCFO) device for continuous monitoring of both cerebral blood flow (CBF) and oxygenation in neonatal piglets and preterm infants. METHODS: DSCFO uses two small laser diodes as focused-point and a tiny CMOS camera as a high-density two-dimensional detector to detect spontaneous spatial fluctuation of diffuse laser speckles for CBF measurement, and light intensity attenuations for cerebral oxygenation measurement...

BACKGROUND: Inguinal hernia is a relatively common condition. Most patients with inguinal hernia require surgery. At present, mesh repair is one of the most effective methods to treat inguinal hernia, but insertion of the mesh can cause inflammation. Dexamethasone (DEX) can treat inflammation, but the mechanism by which DEX alleviates inflammation caused by inguinal hernia mesh placement remains unclear. METHOD: We randomly divided rats into groups: negative control (NC), inguinal hernia (IH), polypropylene mesh (PM), DEX treatment, and miR-155 treatment groups...

OBJECTIVE: Craniovertebral junction (CVJ) abnormalities are common and well documented in mucopolysaccharidosis type I-Hurler syndrome (MPS IH), often causing severe spinal canal narrowing. However, the requirement for surgical decompression and/or fusion is uncommon. Although hematopoietic cell transplant (HCT) has been shown to prolong the lives of patients with MPS IH, its effect in halting or reversing musculoskeletal abnormalities is less clear. Unfortunately, there are currently no universal guidelines for imaging or indication for surgical interventions in these patients...

INTRODUCTION: Although higher incidence of cancer represents a major burden for obstructive sleep apnea (OSA) patients, the molecular pathways driving this association are not completely understood. Interestingly, adenosinergic signaling has emerged as a powerful immune checkpoint driving tumor development and progression. METHODS: Here, we explored the expression of the adenosinergic ecto-enzymes CD39 and CD73 in T-lymphocytes of OSA patients without any evidence of cancer, as well as their soluble forms in plasma (sCD39 and sCD73), along with adenosine...

Background: Incisional hernia (IH) is a common complication of abdominal surgery affecting between 12.8% and 30% of patients. In spite of this, rates of IH repair remain low, at around 5% in the literature. We aimed to assess the rate of IH repair in the UK across surgical specialties and the cost burden associated with IH repair. Methods: This is a retrospective observational study of patients undergoing abdominal surgery in England between 2012 and 2022 using the Hospital Episode Statistics (HES) database...

BACKGROUND: Intermittent hypoxia (IH) is emerging as a cost-effective nonpharmacological method for vital organ protection. We aimed to assess the effects of a short-term moderate intermittent hypoxia preconditioning protocol (four cycles of 13% hypoxia lasting for 10 min with 5-min normoxia intervals) on acute hypoxic injury induced by sustained hypoxic exposure (oxygen concentration of 11.8% for 6 h). METHODS: One hundred healthy volunteers were recruited and randomized to the IH group and the control group to receive IH or sham-IH preconditioning for 5 days, respectively, and then were sent to a hypoxic chamber for simulated acute high-altitude exposure (4500 m)...

Intracranial hypotension (IH) represents a syndrome secondary to low cerebrospinal fluid pressure. This case of IH following a lumbar drain inserted before the excision of a left intraconal lesion, leading to recurrent post-operative unilateral subdural and extradural collections, was treated successfully with the evacuation of the collection and simultaneous epidural blood patch (EBP) injection. Our report provides an important perspective on the management of IH with recurrent intracranial collections and reiterates that IH should be considered when dealing with recurrent unilateral intracranial collections in the post-operative period...

Obstructive sleep apnea (OSA) is characterized by intermittent repeated episodes of hypoxia-reoxygenation. OSA is associated with cerebrovascular consequences. An enhanced blood-brain barrier (BBB) permeability has been proposed as a marker of those disorders. We studied in mice the effects of 1 day and 15 days intermittent hypoxia (IH) exposure on BBB function. We focused on the dorsal part of the hippocampus and attempted to identify the molecular mechanisms by combining in vivo BBB permeability (Evans blue tests) and mRNA expression of several junction proteins (zona occludens (ZO-1,2,3), VE-cadherin, claudins (1,5,12), cingulin) and of aquaporins (1,4,9) on hippocampal brain tissues...

The evaluation of water sorption and solubility is pivotal for the development of new resin-based restorative materials with the potential for clinical application. The purpose of the present study was to evaluate the influence of the specimen dimension, water immersion protocol, and surface roughness on the water sorption and solubility of three resin-based restorative materials. Disk-shaped specimens of 15 mm × 1 mm, 10 mm × 1 mm, and 6 mm × 1 mm were produced with a composite resin (Z100), a resin cement (RelyX ARC), and an adhesive system (Single Bond 2-SB2)...

Mature oligodendrocytes (OLG) are the myelin-forming cells of the central nervous system. Recent work has shown a dynamic role for these cells in the plasticity of neural circuits, leading to a renewed interest in voltage-sensitive currents in OLG. Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels and their respective current (I h ) were recently identified in mature OLG and shown to play a role in regulating myelin length. Here we provide a biochemical and electrophysiological characterization of HCN channels in cells of the oligodendrocyte lineage...

Objective: Isorhamnetin (IH) has been reported to have significant anti-inflammatory effects in various diseases, but its role and mechanism in AKI remain unclear. This study aimed to explore the potential role and mechanism of isorhamnetin in inhibiting macrophage related inflammation and improving AKI injury. Methods: We established an AKI mouse model by intraperitoneal injection of cisplatin in vivo , and constructed an inflammatory cell model by stimulating RAW264.7 cells with LPS. Creatinine and urea nitrogen were measured to evaluate the changes of renal function in AKI mice...
