Patients with end-stage renal disease often have neurological disorders, with a higher incidence of memory impairment or epilepsy than in the general population. Patients undergoing hemodialysis are particularly exposed to the biological effects of uremic toxins. Indoxyl sulfate (IS) is one of the most potent uremic toxins; however, its possible effects on seizure susceptibility or memory functions have yet to be elucidated. In the current study, we focused on investigating the possible convulsant and amnesic effects of IS in recognized animal models. The study was performed on adult male Swiss mice. IS and scopolamine (SCO) were administered intraperitoneally (i.p.), and pentylenetetrazole (PTZ) was injected subcutaneously (s.c.). All substances were given as single injections. Acute IS administration (400 mg/kg) led to its accumulation in the brain. IS at doses of 200 and 400 mg/kg decreased the PTZ convulsive threshold, and at the same doses, it did not significantly affect the threshold for electroconvulsions. IS (200 and 400 mg/kg) did not impair learning in the passive avoidance test and did not increase the SCO-induced memory impairment in this test. IS increased lipid peroxidation, decreased the level of reduced glutathione, and reduced the activity of superoxide dismutase and catalase in mouse brains. Exposure to IS did not significantly change the activity of acetylcholinesterase in the brain tissue. This study shows that acute exposure to IS induces oxidative stress in the brain and potentiates PTZ-induced seizures in mice. Further studies are needed to find out whether IS-induced oxidative stress may affect epileptic seizures and/or epileptogenesis.
PURPOSE: Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) is a sudden worsening of symptoms in patients with Chronic Obstructive Pulmonary Disease (COPD), such as cough, increased sputum volume, and sputum purulence. COPD and AECOPD are characterized by damage to cilia and increased mucus secretion. Mucociliary clearance (MCC) functions as part of the primary innate system of the lung to remove harmful particles and pathogens together with airway mucus and is therefore crucial for patients with COPD.
METHODS: AECOPD was induced by cigarette smoke exposure (80 cigarettes/day, 5 days/week for 12 weeks) and lipopolysaccharide (LPS) instillation (200 μg, on days 1, 14, and 84). Rats administered Lianhua Qingke (LHQK) (0.367, 0.732, and 1.465 g/kg/d) or Eucalyptol, Limonene, and Pinene Enteric Soft Capsules (ELP, 0.3 g/kg/d) intragastrically. Pulmonary pathology, Muc5ac+ goblet cell and β-tubulin IV+ ciliated cells, and mRNA levels of forkhead box J1 (Foxj1) and multiciliate differentiation and DNA synthesis associated cell cycle protein (MCIDAS) were assessed by hematoxylin and eosin staining, immunofluorescence staining, and RT-qPCR, respectively. Ciliary morphology and ultrastructure were examined through scanning electron microscopy and transmission electron microscopy. Ciliary beat frequency (CBF) was recorded using a high-speed camera.
RESULTS: Compared to the model group, LHQK treatment groups showed a reduction in inflammatory cell infiltration, significantly reduced goblet cell and increased ciliated cell proportion. LHQK significantly upregulated mRNA levels of MCIDAS and Foxj1, indicating promoted ciliated cell differentiation. LHQK protected ciliary structure and maintained ciliary function via increasing the ciliary length and density, reducing ciliary ultrastructure damage, and ameliorating random ciliary oscillations, consequently enhancing CBF.
CONCLUSION: LHQK enhances the MCC capability of ciliated cells in rat with AECOPD by preserving the structural integrity and beating function of cilia, indicating its therapeutic potential on promoting sputum expulsion in patients with AECOPD.
CY 5021 is a Phase 2, double-blind, randomized, placebo-controlled, multiple dose study of reldesemtiv in 2 sequential ascending dose cohorts of patients with SMA. Patients will be randomized 2:1 to receive reldesemtiv or placebo twice daily for 8 weeks. Patients randomized to reldesemtiv in Cohort 1 will receive a dose of 150 mg twice daily and patients randomized to reldesemtiv in Cohort 2 will receive 450 mg twice daily. Within each cohort, randomization will be stratified by ambulatory status (ambulatory versus non ambulatory).

The primary objective of the study is to determine the PD effects of reldesemtiv on measures of pulmonary function, respiratory function, muscle strength, and motor function. Other PD measures include changes in the timed up and go (TUG) test, a 6-minute walk test (6MWT), and patient and investigator global assessments. Secondary objectives include the safety of multiple doses of reldesemtiv and an evaluation of the pharmacokinetics of reldesemtiv.
All participants were instructed to masticate gum containing Tulsi extract for a duration of 5 minutes and subsequently discard the gum. Salivary samples were collected before commencing gum chewing and after 30 minutes following the conclusion of chewing gum for 5 minutes.
Participants assigned to the Chen Style Tai Chi group will attend a 1-hour long session of tai chi once a week for 12 weeks. Participants will be required to concurrently see a mental health professional for the 12 week treatment period. How often they seek counseling is up to the participant.
In the control arm, genotyping will be performed for retrospective analysis, but the genotype information will not be used to guide treatment. Children in this study arm will proceed randomisation between doubling ICS dosage (n=75) or LABA treatment (n=75), the two most commonly preferred add-on options among paediatric pulmonologists in the Netherlands. The investigators choose to randomize between both treatments options, since international guidelines do not agree on the preferred treatment option.
The primary purpose of this feasibility study is to assess human user acceptance of the device during 2 lab sessions (aim 1) from which the persons will proceed to 5 lab sessions (aim 2) and during in-home use (aim 3). The in-home aim will also include control persons to allow exploratory collection of clinical data that may provide preliminary outcome data to properly power a future phase 2 randomized clinical trial. The open label extension will provide information on the efficacy of using the device long-term.

While 45 persons may appear to be a larger than normal number for a device feasibility trial, because Parkinsons patients have a wide range of clinical symptoms, in order to acquire any meaningful data, some "spread" must be achieved. For example, 3 individuals in several different symptomatic categories. Further, there is some chance of attrition. Lastly, to be clear, details of device design may continue to be modified throughout the study.
PROBLEM TO BE SOLVED: To keep excellent adsorption characteristics developing new catalytic function over a long period by forming a metal oxide having photo-catalytic action in an apatite crystal structure by coprecipitation to cause ion exchange treatment. SOLUTION: A metal-modified apatite is produced by coprecipitating an apatite and a metal oxide having photo-catalytic action to composite the above components in atomic order and subjecting a part of the metal ion in the apatite crystal to ion-exchange with the metal ion of the metal oxide. The apatite is e.g. hydroxyapatite, fluoroapatite, etc., preferably calcium hydroxyapatite and the metal oxide is e.g. zirconium oxide, iron oxide, tungsten oxide, etc., preferably titanium oxide (TiO2). The content of the metal ion in the apatite crystal is at most about 15 mol%, preferably about 3-11 mol%.
Fibrogenesis is initially performed during tissue damage to protect the remaining tissues from the progressive death of epithelial cells, infiltration of immune and inflammatory cells, and local degrading enzymes. Inflammation can lead to excessive extracellular matrix deposition by fibroblasts and the induction of fibrosis in many organs, such as the liver. MiRNAs are small noncoding RNAs that mediate mRNA repression or destabilization, leading to translational repression. Owing to the wide range of roles of miRNAs in the development of fibrosis, especially liver fibrosis, many studies have focused on their diagnostic, regulatory, and therapeutic roles. In this study, we used medical science and general databases, including PubMed, Elsevier, Scopus, Nature, and Google Scholar, to find valid studies on the different roles of miRNAs in liver fibrosis. Because a large number of miRNAs with regulatory, diagnostic, and therapeutic roles in diseases associated with liver fibrosis have been identified and reported in this study, special attention to these elements is needed in the future of healthcare systems.
BACKGROUND: Gastric cancer is the fifth most prevalent malignancy globally and the fourth major contributor to cancer-related mortality. The comparative effectiveness of robotic gastrectomy (RG) versus laparoscopic gastrectomy (LG) at different stages of gastric cancer is unclear regarding surgical and survival outcomes. We compared surgical and survival outcomes between RG and LG in early-stage (cStage I) and advanced (cStage II/III) gastric cancers to elucidate the difference in the efficacy of RG across various stages of gastric cancer.
METHODS: We identified 299 patients (LG, 170; RG, 129) with cStage II/III disease and 569 (LG, 455; RG, 114) with cStage I disease who underwent either LG or RG. Following propensity score matching for RG and LG, 118 pairs were selected for cStage II/II and 113 pairs for cStage I. Surgical and survival outcomes of LG and RG were separately compared for cStage II/III and cStage I.
RESULTS: In cStage II/III, RG showed significantly fewer intra-abdominal complications of Clavien-Dindo (C.D.) Grade ≥ III in the RG group than in the LG group (LG = 8.5 vs. RG = 1.7%, P = 0.033). Multivariate analysis identified LG as an independent risk factor for intra-abdominal complications of C.D. Grade ≥ III (OR 5.69, 95% CI 1.17-27.70, P = 0.031). However, in cStage I, no difference in surgical outcomes between LG and RG was observed. No differences were observed in survival outcomes between LG and RG in both cStage I or cStage II/III.
CONCLUSIONS: The real benefit of RG was demonstrated in surgical outcomes, especially for advanced-stage gastric cancer.
PURPOSE: Cancer treatment with alpha-emitter-based radioligand therapies (α-RLTs) demonstrates promising tumor responses. Radiolabeled peptides are filtered through glomeruli, followed by potential reabsorption of a fraction by proximal tubules, which may cause acute kidney injury (AKI) and chronic kidney disease (CKD). Because tubular cells are considered the primary site of radiopeptides' renal reabsorption and potential injury, the current use of kidney biomarkers of glomerular functional loss limits the evaluation of possible nephrotoxicity and its early detection. This study aimed to investigate whether urinary secretion of tubular injury biomarkers could be used as an additional non-invasive sensitive diagnostic tool to identify unrecognizable tubular damage and risk of long-term α-RLT nephrotoxicity.
METHODS: A bifunctional cyclic peptide, melanocortin 1 ligand (MC1L), labeled with [203Pb]Pb-MC1L, was used for [212Pb]Pb-MC1L biodistribution and absorbed dose measurements in CD-1 Elite mice. Mice were treated with [212Pb]Pb-MC1L in a dose-escalation study up to levels of radioactivity intended to induce kidney injury. The approach enabled prospective kidney functional and injury biomarker evaluation and late kidney histological analysis to validate these biomarkers.
RESULTS: Biodistribution analysis identified [212Pb]Pb-MC1L reabsorption in kidneys with a dose deposition of 2.8, 8.9, and 20 Gy for 0.9, 3.0, and 6.7 MBq injected [212Pb]Pb-MC1L doses, respectively. As expected, mice receiving 6.7 MBq had significant weight loss and CKD evidence based on serum creatinine, cystatin C, and kidney histological alterations 28 weeks after treatment. A dose-dependent urinary neutrophil gelatinase-associated lipocalin (NGAL, tubular injury biomarker) urinary excretion the day after [212Pb]Pb-MC1L treatment highly correlated with the severity of late tubulointerstitial injury and histological findings.
CONCLUSION: Urine NGAL secretion could be a potential early diagnostic tool to identify unrecognized tubular damage and predict long-term α-RLT-related nephrotoxicity.
BACKGROUND: Local recurrent brain metastases are defined as lesions that recur in the brain at the same site after a previous local therapy. In patients already submitted to surgery, a second operation may be potentially challenging due to scar formation, infiltration of cerebral vessels or eloquent brain areas and local effect of previous radiotherapy. The aim of this study is to retrospectively review the results and complications of a second surgical treatment in a series of local recurrent lesions and to review the literature on this topic.
METHODS: 37 patients submitted to surgery for a local, histologically confirmed, recurrent brain metastases between 2000 and 2022 were retrospectively analyzed with respect to the following parameters: age, histology, anatomic location, time to recurrence, previous radiotherapy, size of recurrent tumors, preoperative and postoperative Karnofsky Performance Status (KPS) score, recursive partitioning analysis (RPA) class and graded prognostic assessment (GPA) score, surgery-related complications and the presence of further cerebral metastases. Overall survival (OS) was calculated using the Kaplan-Meier method. A multivariate Cox proportional hazard model was developed using stepwise regression (forwards selection) with predictive variables that were significant in the univariate analyses.
RESULTS: A significant improvement of post-operative KPS status was obtained after second surgery. At multivariate analysis better results in terms of OS were achieved in patients with a pre-operative KPS ≥ 70 and in patients who had received radiotherapy after the initial surgery. No significant postoperative complications related to previous treatments were observed.
CONCLUSIONS: Surgical resection of local recurrent brain metastases may improve patients ́ neurologic conditions allowing more time for systemic therapies to act with a low incidence of surgery-related morbidity and mortality. However, careful patient selection with a fair pre-operative clinical status seems mandatory to achieve the best post-operative results, since uniform treatment-paradigms cannot be established yet, due to the highly heterogeneous patient cohort.

BACKGROUND/AIM: Spontaneous spinal epidural hematoma (SSEH) is a rare but serious condition, accounting for less than 1% of spinal lesions, with an incidence of 0.1 per 100,000 annually. Discovered by Jackson in 1869, around 40-50% of SSEH cases often lack a definitive cause, though risk factors, such as anticoagulant usage, vascular malformations, and hypertension are recognized. Symptoms vary from mild pain to severe neurological impairments like paraparesis, depending on the spinal cord compression level. Prompt treatment, usually involving spinal decompression and hematoma removal, is crucial, especially in cases of neurological decline. The study aims to provide comprehensive analysis of SSEH through examination of by patient cases, critical prognostic factors, and therapeutic strategies, based on demographics, clinical data, and outcomes observed at the Tri-Service General Hospital.
PATIENTS AND METHODS: This retrospective study, spanning 2003-2023 at the Tri-Service General Hospital, analyzed 14 patients with SSEH. It examined demographics, risk factors, clinical and radiological profiles, treatments, outcomes, and prognoses, using SPSS software (version 22.0) and adhering to the Modified Rankin Scale (mRS) and the American Spinal Injury Association (ASIA) impairment scale guidelines for data analysis.
RESULTS: In this study of 14 patients with SSEH, 93% underwent urgent surgery, including total laminectomy or open-door laminoplasty, while 7% received conservative treatment. Post-surgery, 69.2% showed favorable outcomes (mRS ≤2) in the one-year follow-up, while 30.8% had poorer results (mRS 3-4). A significant negative correlation was noted between initial ASIA scores and one-year mRS outcomes, suggesting less initial impairment predicts better recovery. These findings indicated that a moderate positive correlation between treatment delay and one-year mRS scores. Nevertheless, factors, such as age, antiplatelet use, spinal levels with hematoma localization, and myelopathy signs observed before treatment did not demonstrate any significant effects on neurological outcomes during the one-year follow-up.
CONCLUSION: Patients with minor initial deficits or those receiving early surgery, preferably within 12-36 h of symptom onset, exhibit better neurological recovery. Poor prognosis correlates with high International Normalized Ratio (INR) on anticoagulants, hematoma size, lumbar involvement, or severe motor issues. Rapid surgical hematoma evacuation is advised. Our study supports recovery of neurological function following surgical intervention in all cases, highlighting the potential efficacy of surgical decompression even in severe and prolonged instances of SSEH.
BACKGROUND: Fear of pain is known to influence pain perception and worsen pain outcomes. However, its relationship with pain threshold remains unclear. Negative emotional states, namely depression, anxiety, and stress, have been found to increase fear of pain. Previous pain experiences, both undergone and observed, can also influence fear of pain. Furthermore, healthcare students' interactions with pain patients may be influenced by fear of pain and pain perception. This study aimed to assess fear of pain among Portuguese medical and nursing students, analyse its association with sex, negative emotional states, previous pain experiences, and curricular year, and evaluate the influence of fear of pain on heat pain threshold.
METHODS: A survey based on validated Portuguese questionnaires was carried out. Participants were then invited for quantitative sensory tests to assess heat pain threshold.
RESULTS: Fear of pain was similar for medical and nursing students. Female students presented a higher fear of medical pain. Stress was associated with an increased fear of severe pain. Previous painful experiences, particularly those involving medical procedures, have been found to be variably associated with fear of pain, depending on the type and characteristics of these experiences. No associations were found between fear of pain and curricular year, nor between heat pain threshold and sex or fear of pain.
CONCLUSIONS: This study highlights relevant aspects of the emotional and cognitive modulation of fear of pain and pain perception in medical and nursing students. The influence of previous pain experiences on fear of pain is also essential because healthcare students are frequently exposed to painful medical situations during their courses. As altered pain perception can influence their role as future healthcare professionals, the study of fear of pain and its modulators in healthcare students represents an important research field.
Although numerous barriers for clinical germline cancer predisposition testing exist, the increasing recognition of deleterious germline DNA variants contributing to myeloid malignancy risk is yielding steady improvements in referrals for testing and testing availability. Many germline predisposition alleles are common in populations, and the increasing number of recognized disorders makes inherited myeloid malignancy risk an entity worthy of consideration for all patients regardless of age at diagnosis. Germline testing is facilitated by obtaining DNA from cultured skin fibroblasts or hair bulbs, and cascade testing is easily performed via buccal swab, saliva, or blood. Increasingly as diagnostic criteria and clinical management guidelines include germline myeloid malignancy predisposition, insurance companies recognize the value of testing and provide coverage. Once an individual is recognized to have a deleterious germline variant that confers risk for myeloid malignancies, a personalized cancer surveillance plan can be developed that incorporates screening for other cancer risk outside of the hematopoietic system and/or other organ pathology. The future may also include monitoring the development of clonal hematopoiesis, which is common for many of these cancer risk disorders and/or inclusion of strategies to delay or prevent progression to overt myeloid malignancy. As research continues to identify new myeloid predisposition disorders, we may soon recommend testing for these conditions for all patients diagnosed with a myeloid predisposition condition.
We systematically evaluated the effect of continuous nursing on surgical site wound infections and postoperative complications in colorectal cancer (CRC) patients with stomas. Computerised searches of Embase, PubMed, Cochrane Library, China National Knowledge Infrastructure and Wanfang databases were conducted to collect clinical studies on CRC patients receiving continuous nursing interventions after colorectal stoma surgery; the search period was from the establishment of each database to August 2023. Two researchers independently screened the literature, extracted the data and completed a literature quality assessment. The meta-analysis was performed using Stata 17.0 and included 20 studies with 1759 patients. The meta-analysis showed that continuous nursing significantly lowered the rates of surgical site wound infection (risk ratio [RR] = 0.24, 95% confidence interval [CI]: 0.14-0.43, p < 0.001) and postoperative complications (RR = 0.30, 95% CI: 0.23-0.39, p < 0.001) for CRC stoma patients compared with the control group. Therefore, continuous nursing intervention should be promoted for use in clinical care.
A one time blood draw of 50mL or 15mL will be performed using a vein in the participants arm. Existing venous access will be used for the blood draw in preference of new venipuncture. Participants will be enrolled in equal numbers from three categories determined by their observed clinical course: (1) participants without HIT testing negative for heparin/PF4 antibodies (controls); (2) participants without HIT testing positive for heparin/PF4 antibodies (seroconversion cases); (3) participants with HIT testing positive for both heparin/PF4 antibodies (HIT cases).
A composition interacts with a biological cell system that includes bioactive molecules with biomolecular surfaces, cellular components and water molecules with a specific density. The composition includes a biologically active component that is constructed to increase an activity of a biological cell system by increasing the hydration of one or more components of that cell system. The biologically active component may include a primary carbohydrate clathrate subcomponent that increases the H-bonded structure of water, and a secondary solute subcomponent. The biologically active component may include an inclusion complex that is made up of a clathrate component and a complex-forming compound. The clathrate subcomponent may include amyloses or cyclodextrins. There is also a beverage and a method that improves cellular hydration in an animal, such as a human.
