For many adult human organs, tissue regeneration during chronic disease remains a controversial subject. Regenerative processes are easily observed in animal models, and their underlying mechanisms are becoming well characterized1-4, but technical challenges and ethical aspects are limiting the validation of these results in humans. We decided to address this difficulty with respect to the liver. This organ displays the remarkable ability to regenerate after acute injury, although liver regeneration in the context of recurring injury remains to be fully demonstrated. Here we performed single-nucleus RNA sequencing (snRNA-seq) on 47 liver biopsies from patients with different stages of metabolic dysfunction-associated steatotic liver disease to establish a cellular map of the liver during disease progression. We then combined these single-cell-level data with advanced 3D imaging to reveal profound changes in the liver architecture. Hepatocytes lose their zonation and considerable reorganization of the biliary tree takes place. More importantly, our study uncovers transdifferentiation events that occur between hepatocytes and cholangiocytes without the presence of adult stem cells or developmental progenitor activation. Detailed analyses and functional validations using cholangiocyte organoids confirm the importance of the PI3K-AKT-mTOR pathway in this process, thereby connecting this acquisition of plasticity to insulin signalling. Together, our data indicate that chronic injury creates an environment that induces cellular plasticity in human organs, and understanding the underlying mechanisms of this process could open new therapeutic avenues in the management of chronic diseases.
High altitude retinopathy (HAR) is a common ocular disorder that occurs on ascent to high altitude. There are many clinical symptoms, retinal vascular dilatation, retinal edema and hemorrhage are common. These usually do not or slightly affect vision; rarely, severe cases develop serious or permanent vision loss. At present, the research progress of HAR mainly focuses on hemodynamic changes, blood-retinal barrier damage, oxidative stress and inflammatory response. Although the related studies on HAR are limited, it shows that HAR still belongs to hypoxia, and hypobaric hypoxia plays an aggravating role in promoting the development of the disease. Various studies have demonstrated the correlation of HAR with acute mountain sickness (AMS) and high-altitude cerebral edema (HACE), so a deeper understanding of HAR is important. The slow ascent rates and ascent altitude are the key to preventing any altitude sickness. Research on traditional chinese medicine (TCM) and western medicine has been gradually carried out. Further exploration of the pathogenesis and prevention strategies of HAR will provide better guidance for doctors and high-altitude travelers.
Opioid-associated brain injury may involve selective regions, including the hippocampi alone, globi pallidi, and cerebellar hemispheres. Opioid-associated amnestic syndrome, for example, is one clinical correlate of hippocampal injury as manifest by MRI abnormality. When all three regions are involved in what may be a more fulminant injury, the syndrome is termed "cerebellar, hippocampal, and basal nuclei transient edema with restricted diffusion (CHANTER)", initially described in 2019. Until now, to our knowledge, there have been no histopathologic correlates to the imaging findings specifically in CHANTER syndrome. Here, for the first time, we present histopathologic findings of the post-mortem brain from a patient who died from complications of CHANTER syndrome following fentanyl intoxication. These observations included microhemorrhage, reactive and necrotic vasculature, eosinophilic neuronal necrosis, axonal swelling and spheroids, and frank infarction. The findings support previous experimental models implicating both hypoxic-ischemic and cytotoxic mechanisms in the tissue damage associated with CHANTER syndrome, though further work is needed to better characterize the exact cellular pathways involved to develop targeted treatments.
BACKGROUND: Constipation is among the most common symptoms prompting a consultation with a paediatric gastroenterologist. While most patients will respond to lifestyle and dietary changes and conventional therapy, some may require diagnostic studies.
AIM: To review the diagnostics studies used to evaluate children with functional constipation.
MATERIALS AND METHODS: There is no evidence to support the routine use of abdominal X-rays in the evaluation of paediatric constipation. Colon transit by radiopaque markers (ROM) should be indicated when medical history does not match clinical findings, to guide colon manometry (CM) performance and to discriminate between faecal incontinence from functional constipation and non-retentive faecal incontinence. Colon scintigraphy may be useful as an alternative to ROM. Lumbar spine MRI may be indicated to evaluate for spinal abnormalities. The role of defecography has not been properly evaluated in children. Anorectal manometry in children is indicated primarily to evaluate anal resting pressure, presence and quality of the recto-anal inhibitory reflex and simulated defecation manoeuvres. The CM is indicated to guide surgical interventions after failing medical therapy.
CONCLUSIONS: The goal of these studies is to identify treatable causes of constipation. Most of these studies are designed to evaluate anatomy, transit and/or colon/rectum motility function and are primarily indicated in those who fail to respond to conventional therapy.
Observational retrospective study to analyze the effect of heatwaves on interstitial glucose in adult patients with type 1 diabetes mellitus treated with advanced hybrid closed-loop systems in the Castilla-La Mancha region (southcentral Spain). Main objective is the difference in time in range of intersticial glucose between 3.0-10 mmol/L (70-180 mg/d) measured throught real-time continuous glucose monitoring during the two consecutive greatest heatwave during summer 2024 (5th-26th August) comparted to the following period (27th August to 17th September). Data analysis is conducted using SPSS (Chicago, IL) statistics software. Results are presented as mean ± SD values or percentages. A paired Student's t-test or a Wilcoxon signed-rank test were used for the analysis of differences. Comparisons between proportions were analyzed using a chi-squared test. A P value \< 0.05 was considered statistically significant. The protocol was approved by the reference Castilla-La Mancha Public Health Institute Ethic Committee.
Intrinsic and acquired drug resistance remain major obstacles in the treatment of cancer. Accumulating evidence indicates that in some malignancies P-glycoprotein (Pgp) can confer resistance, and that its reversal can improve therapeutic outcome. Clinical trials investigating Pgp antagonists have been hampered by the occurrence of unpredictable pharmacokinetic interactions, which have required dose reductions of the chemotherapeutic agents to avert excessive toxicity. Tariquidar (XR9576) is a new Pgp antagonist that is more potent and has prolonged activity. Phase I trials with paclitaxel, vinorelbine, and docetaxel have demonstrated that tariquidar (XR9576) has minimal pharmacokinetic interactions while surrogate studies have confirmed in vivo inhibition of Pgp-mediated drug transport.This study seeks to determine the pharmacokinetic interaction, if any between docetaxel and tariquidar and to evaluate the potential for activity in lung, ovarian, primary peritoneal, fallopian tube and cervical cancers. Renal cell cancer has been added in a 3/1/06 amendment. The secondary goal is to evaluate the impact of tariquidar on uptake of (99m)Tc-sestamibi in recurrent or metastatic tumors of patients with lung, ovarian, renal or cervical cancer.

Assess the efficacy and safety of ADA compared to ADA/MTX in patients with psoriasis. Many studies of ADA in rheumatoid and psoriatic arthritis have allowed patients on stable doses of MTX to continue on MTX while being treated with ADA. There has been no prospective trial of MTX and ADA concomitantly in psoriasis. Safety of ADA monotherapy vs. combination ADA/MTX will be compared.

Compare anti-ADA antibody formation and serum ADA levels in patients on ADA compared with those on combination ADA and MTX. ADA is a fully human monoclonal antibody to TNF-a. More recent advances in detection of ADA antibodies have shown that many patients develop antibodies to ADA while on treatment and some of these antibodies are neutralizing. The presence of anti-ADA antibodies has been correlated with loss of therapeutic response in many disease states.
Patients will receive ketoconazole, 400 mg three times a day. Study treatment period will be during 6 months or up to progression disease, unacceptable toxicity, death or withdraw from the study for any reason.
Increased energy intake from carbohydrates has been associated with major cardiovascular outcomes. Mice fed a highly-refined carbohydrate (HC) diet develop cardiac hypertrophy and inflammation. During cardiac injury, NLRP3 inflammasome is activated which results in a local inflammatory response. In this study, we hypothesized that a nom-hypoglycemic dose of glibenclamide may reverses sugar diet-induced cardiac damage by NRLP3 inflammasome inhibition. Mice were fed the HC diet for eight weeks and divided into a group treated with glibenclamide (20 mg/kg, gavage) and another with vehicle for four weeks. Afterward, hearts were excised for morphometric analysis and ex vivo function determination. NLRP3 inflammasome activation was investigated by western blotting and in situ fluorescent detection of reactive oxygen species (ROS) and active caspase-1. The HC diet promotes heart hypertrophy and collagen deposition, which were reverted by glibenclamide without ameliorating HC diet-induced insulin resistance. Changes in cardiac performance were observed in vivo by invasive catheterization and in Langendorff-perfused hearts due to the HC diet, which were prevented by glibenclamide. Hearts from HC diet mice had increased levels of NLRP3 and cleaved IL-1β. Glibenclamide reversed ROS production and caspase-1 activity induced by HC diet. These findings suggest glibenclamide's cardioprotective effects on heart damage caused by the HC diet are related to its inhibitory action on the NLRP3 inflammasome.
IgA nephropathy is the most prevalent primary glomerular disease worldwide and an important cause of end stage renal disease. Clinical course varies from long term stable renal functions with minimal proteinuria and microscopic hematuria to rapidly progressive glomerulonephritis with crescents on renal biopsy which progresses to end stage renal disease in a very short time.

In current practice the diagnosis is made with renal biopsy. A less invasive procedure for diagnosis is not present and no serum biomarkers for clinical follow-up, treatment response and prognosis are available. For that reason follow-up of the disease is enabled with indirect markers of renal function like proteinuria, serum creatinine and glomerular filtration rate. These markers are not specific for IgA nephropathy. The lack of disease specific markers hinders the standardization of patient follow-up and treatment. Development of specific and sensitive, repeatable, histopathological and clinical markers for diagnosis, follow up and treatment response in IgA nephropathy the most prevalent primary glomerular disease affecting many patients worldwide will offer prospects of diagnosis and improved prognostication.
Patients with existing or a history of medication-related osteonecrosis of the jaw (MRONJ) are considered to be at a higher risk of further developing MRONJ, particularly if dental extractions are necessary. It is assumed that their underlying risk factors predispose them to developing MRONJ and they are allocated into an 'elevated risk group'. There is no evidence to quantify this risk level; however, it has led to an avoidance of dental extractions in this cohort. However, avoidance of dental extractions is not a realistic treatment option to prevent MRONJ and there is emerging evidence that inflammatory dental disease, such as peri-apical pathology or periodontal disease, can trigger the pathogenesis of MRONJ. The current case series retrospectively reviewed 28 patients with existing or a history of MRONJ who underwent dental extractions (n = 65) via our departmental protocol, which includes elective circumferential socket alveoplasty and primary closure. Our outcomes show that MRONJ did not develop at the new extraction site, with a post-operative review period of at least six months. These results provide promising evidence that dental extractions can be performed in this group of patients with <1% risk of developing MRONJ at the new surgical site, if appropriate measures are undertaken.
Participants will receive a boosted protease inhibitor (bPI) (limited to darunavir \[DRV\] or atazanavir with low-dose ritonavir \[rtv\] or cobicistat \[COBI\], or lopinavir with rtv) combined with emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) up to Week 52. After Week 52, all participants will receive the D/C/F/TAF tablet in a 44 week extension phase (up to Week 96).
Chronic hepatitis B poses a significant global burden, modulating immune cells, leading to chronic inflammation and long-term damage. Due to its hepatotropism, the hepatitis B virus (HBV) cannot infect other cells. The mechanisms underlying the intercellular communication among different liver cells in HBV-infected individuals and the immune microenvironment imbalance remain elusive. Exosomes, as important intercellular communication and cargo transportation tools between HBV-infected hepatocytes and immune cells, have been shown to assist in HBV cargo transportation and regulate the immune microenvironment. However, the role of exosomes in hepatitis B has only gradually received attention in recent years. Minimal literature has systematically elaborated on the role of exosomes in reshaping the immune microenvironment of the liver. This review unfolds sequentially based on the biological processes of exosomes: exosomes' biogenesis, release, transport, uptake by recipient cells, and their impact on recipient cells. We delineate how HBV influences the biogenesis of exosomes, utilizing exosomal covert transmission, and reshapes the hepatic immune microenvironment. And based on the characteristics and functions of exosomes, potential applications of exosomes in hepatitis B are summarized and predicted.
Chronic pain remains poorly managed. The integration of immersive technologies (ie, virtual reality [VR]) with neuroscience-based principles may provide effective pain treatment by targeting cognitive and affective neural processes that maintain pain and therefore potentially changing neurobiological circuits associated with pain chronification and amplification. We tested the effectiveness of a novel VR neuroscience-based therapy (VRNT) to improve pain-related outcomes in n = 31 participants with chronic back pain, evaluated against usual care (waitlist control; n = 30) in a 2-arm randomized clinical trial ( NCT04468074) . We also conducted pre-treatment and post-treatment MRI to test whether VRNT affects brain networks previously linked to chronic pain and treatment effects. Compared with the control condition, VRNT led to significantly reduced pain intensity (g = 0.63) and pain interference (g = 0.84) at post-treatment vs pre-treatment, with effects persisting at 2-week follow-up. These improvements were partially mediated by reduced kinesiophobia and pain catastrophizing. Several secondary clinical outcomes were also improved by VRNT, including disability, quality of life, sleep, and fatigue. In addition, VRNT was associated with increases in dorsomedial prefrontal functional connectivity with the superior somatomotor, anterior prefrontal and visual cortices, and decreased white matter fractional anisotropy in the corpus callosum adjacent to the anterior cingulate, relative to the control condition. Thus, VRNT showed preliminary efficacy in significantly reducing pain and improving overall functioning, possibly through changes in somatosensory and prefrontal brain networks.
Exposure to fine particulate matter (PM) disrupts the function of airway epithelial barriers causing cellular stress and damage. However, the precise mechanisms underlying PM-induced cellular injury and the associated molecular pathways remain incompletely understood. In this study, we used intratracheal instillation of PM in C57BL6 mice and PM treatment of the BEAS-2B cell line as in vivo and in vitro models, respectively, to simulate PM-induced cellular damage and inflammation. We collected lung tissues and bronchoalveolar lavage fluids to assess histopathological changes, necroptosis, and airway inflammation. Our findings reveal that PM exposure induces necroptosis in mouse airway epithelial cells. Importantly, concurrent administration of a receptor interacting protein kinases 3 (RIPK3) inhibitor or the deletion of the necroptosis effector mixed-lineage kinase domain-like protein (MLKL) effectively attenuated PM-induced airway inflammation. PM exposure dose-dependently induces the expression of Parkin, an E3 ligase we recently reported to play a pivotal role in necroptosis through regulating necrosome formation. Significantly, deletion of endogenous Parkin exacerbates inflammation by enhancing epithelial necroptosis. These results indicate that PM-induced Parkin expression plays a crucial role in suppressing epithelial necroptosis, thereby reducing airway inflammation. Overall, these findings offer valuable mechanistic insights into PM-induced airway injury and identify a potential target for clinical intervention.
The management of marked horizontal bone atrophy represents a critical challenge for traditional implantology procedures. For this purpose, clinicians have developed several protocols and procedures to allow the most suitable and accurate surgical and prosthetic implant rehabilitation. Despite the development of guided bone regeneration methods and the use of small-diameter implants, the rehabilitation of thin bone areas is a clinical dilemma for the medium- and long-term survival of implant-prosthetic therapies. This clinical case evaluates the use of wedge-shaped implants for the full-arch rehabilitation of an atrophic maxilla with a thin ridge. This treatment choice allowed a minimally invasive rehabilitation, avoiding regenerative bone surgery, while respecting biologic and prosthetic limits. Furthermore, evaluation of the implant stability quotient and marginal bone loss values during the first year of follow-up allowed analysis of the behavior of this rehabilitation in fullarch maxillary cases.

Chronological age (CA) is not considered an accurate method for assessing the stage of physical or growth development of an individual in childhood or adolescence. For that reason, skeletal and dental maturation can be used in order to examine the rate of physical maturation of the population. Cervical vertebral maturation (CVM) method uses lateral cephalometric radiography to evaluate skeletal maturity. It is considered the preferable method due to its advantage of avoiding unnecessary extra radiation. The CVM method developed by Baccetti et al. (2005) depends on the morphology of the three cervical vertebrae (C2, C3, and C4), which divided skeletal growth into six stages of based on the morphology of the previously mentioned cervical vertebrae. The Demirjian method is considered as one of the most worldwide used method for assessment of the dental maturation due to its reliability. It depends on panoramic x-rays through which the dental developmental stage of 7 lower left teeth appears, and according to the gender of the patient the sum of values of the teeth will be transform to age through the standard tables of Carmen M. Nolla; 1960.
