Australia has made considerable progress towards the public-health 'elimination' of the hepatitis C virus. Nonetheless, reinfection remains a key challenge, with little understanding regarding the lived complexities of post-cure life among people who inject drugs. Our analysis examines reinfection through the lens of 'time', a largely overlooked and under-utilised analytical concept within the field of hepatitis C. Drawing on qualitative data from a study examining treatment outcomes and reinfection, our analysis concentrates on three participant accounts or 'cases'. Working within a new materialist framework, we combine recent social science scholarship which, firstly, posits cure as a socio-material 'gathering', and secondly, proposes a 'futurology' of hepatitis C and its treatment. We found participant accounts troubled the neat binary of pre- and post-treatment life, instead detailing the challenges of remaining virologically safe while navigating complex, local life-worlds. Rather than a singular, post-treatment future instantiated by cure, participants described the fluid, emergent nature of what we might describe as 'lived' or 'embodied' time, including multiplicities of becoming in a perpetual present. We conclude that our understanding of reinfection needs to move beyond its current, narrow biomedical conception and organising temporal logic to honour and incorporate complexity in practice.
The present invention discloses a comprehensive free-radical removing method capable of removing 99% of a free-radical generation source. The method of the present invention comprises the processes of: preparing a free-radical removing agent; ensuring concentration of the free-radical removing agent; filtering a solvent for the free-radical removing agent; and taking in the solvent for the free-radical removing agent. The present invention has total three essential conditions for satisfying action generation of the free-radical removing agent. First, the free-radical removing agent should have a predetermined concentration. Second, since the free-radical removing agent interacts with macromolecules positioned immediately proximate the free radicals if free radicals are generated due to a very strong free-radical activity, the free-radical removing agent should be positioned near free radicals so that the free-radical removing agent can be combined with free radicals in advance at a more rapid speed. Third, in most cases, after the removing agent interacts with the free radicals, the removing agent becomes new free radicals, and defensive reaction may occur when toxicity of the removing agent is smaller than that of the free radicals. Subsequently, the removing agent can remove 99% of the free radical generation source and can achieve an objective of defending diseases and relieving aging.
BACKGROUND/AIMS: Ultrasonography has a low sensitivity for detecting early-stage hepatocellular carcinoma (HCC) in cirrhotic patients. Non-contrast abbreviated magnetic resonance imaging (aMRI) demonstrated a comparable performance to that of magnetic resonance imaging without the risk of contrast media exposure and at a lower cost than that of full diagnostic MRI. We aimed to investigate the cost-effectiveness of non-contrast aMRI for HCC surveillance in cirrhotic patients, using ultrasonography with alpha-fetoprotein (AFP) as a reference.
METHODS: Cost-utility analysis was performed using a Markov model in Thailand and the United States. Incremental cost-effectiveness ratios were calculated using the total costs and quality-adjusted life years (QALYs) gained in each strategy. Surveillance protocols were considered cost-effective based on a willingness-to-pay value of $4,665 (160,000 Thai Baht) in Thailand and $50,000 in the United States.
RESULTS: aMRI was cost-effective in both countries with incremental cost-effectiveness ratios of $3,667/QALY in Thailand and $37,062/QALY in the United States. Patient-level microsimulations showed consistent findings that aMRI was cost-effective in both countries. By probabilistic sensitivity analysis, aMRI was found to be more cost-effective than combined ultrasonography and AFP with a probability of 0.77 in Thailand and 0.98 in the United States. By sensitivity analyses, annual HCC incidence was revealed as the most influential factor affecting cost-effectiveness. The cost-effectiveness of aMRI increased in settings with a higher HCC incidence. At a higher HCC incidence, aMRI would remain cost-effective at a higher aMRI-to-ultrasonography with AFP cost ratio.
CONCLUSIONS: Compared to ultrasonography with AFP, non-contrast aMRI is a cost-effective strategy for HCC surveillance and may be useful for such surveillance in cirrhotic patients, especially in those with high HCC risks.
Since the procedure was first introduced to clinical practice, Cesarean delivery (CD) has significantly contributed to peripartum maternal and fetal safety when appropriately indicated. Nevertheless, CD rate has significantly increased over the last two decades without parallel improvement in maternal or neonatal outcomes. Globally, one out of three pregnancies would be delivered by CD, resulting in growing surgical, obstetric and financial burden. Over years, long-term sequelae of current CD rate have become evident such as increased incidence of placenta accreta spectrum and exponential rise in CD trend, since 90% of women who had CD are susceptible to CD in future pregnancies. These concerns have triggered a global act to control CD rates within the margins of safe obstetric practice.

The most common indication of CD is labor dystocia. However, the definition of labor dystocia is inconsistent, and standardization of diagnosis has been heavily investigated. The WHO partograph was established at the end of the last century to serve as a tool to recognize labor dystocia and has been universally accepted to verify CD decision However, a cochrane review by Lavender et al. revealed that role of WHO partograph, in improving clinical outcomes, is lacking. In addition, there is no evidence that any published modification of the current partograph is superior to another. The "labor scale," a novel alternative to the classic partograph, was first introduced to literature in 2014. The tool was designed based on evidence-based guidelines and integrates both diagnosis and interventions to manage labor dystocia. Initial data showed that labor scale contributed to decreased incidence of CD and oxytocin administration. However, further studies are required to verify these results.

Commensal bacteria and other microbial organisms (the microbiota), particularly in the intestines, are centrally related to nutrition, metabolism, immunity, inflammation, and endocrine balance. As an initial step toward possible establishment of a biobank of feces that could be used for prospective studies of the relationship of microbiota to cancer and other conditions, we propose a study to evaluate whether fecal microbiota, as well as microbial enzyme expression and function, are reproducibly represented in feces that has been collected with a device that is widely used for fecal occult blood testing (FOBT-CHEK oc). To do so, this study will recruit a convenience sample of 50 volunteers from DCEG and others at NIH. From a single stool, each participant will provide 16 aliquots of feces, half collected with FOBT-CHEK oc and the rest with a larger Sarstedt device. A urine sample and a brief self-administered questionnaire on antibiotics and other medications, serious chronic diseases, and major cancer risk factors will also be obtained. The aliquots will be used for microbiome pyrosequencing, beta-glucuronidase and beta-glucosidase expression and enzymatic activity. Variance within and between collection devices, as well as between individuals, will be quantified. This study will provide insight and quantitative estimates that will be required for formal studies of the relationship of the fecal microbiome to cancer. Under an amendment, to examine the ability of selected antibiotics to stabilize fecal microbial populations when they have been stored at 3 or 7 days prior to freezing, 10 of the same volunteer participants will be asked to provide aliquots of a second stool specimen. Differences between immediate and delayed freezing with or without the antibiotics will be tested by analysis of variance. Under an amendment, up to 100 participants will be enrolled to examine reproducibility of the microbiota with a used commercial colorectal cancer screening device and the stability of the microbiota within individuals over four years, participants will be asked to collect specimens during 2014, exactly as was done during 2010. Assays and anlyses will be analogous to those performed previously.
High-risk coronary plaques (HRP) are characterized in clinical radiological imaging by the presence of low plaque attenuation, a napkin-ring sign (NRS), spotty calcifications (SC) and a positive remodeling index (RI). To evaluate if these signs are detectable in postmortem imaging by a multi-phase postmortem CT angiography (MPMCTA), a retrospective study of a series of autopsy well-documented coronary plaques related to sudden cardiac death (SCD) was performed. Then correlations between histological and radiological findings were described. Fourty SCD cases due to acute coronary syndrome based on clinical history and confirmed at autopsy were selected (28 men and 12 women, age 53.3 ± 10.9). The culprit lesion was mainly situated in the proximal segments of coronary arteries, in the right coronary artery in 23 cases (57.5%), the left anterior descending artery in 13 cases (32.5%), the circumflex artery in 3 cases (7.5%) and in one case in the left main stem. MPMCTA showed a positive RI (≥ 1.1) in 75% of cases with a mean RI 1.39 ± 0.71. RI values were lower in cases with fibrotic plaques. NRS was observed in 40% of cases, low attenuation plaque in 46.3%, and SC in 48.7% of cases. There were significant correlations of the radiological presence of NRS for fibrolipid composition of the plaque (p-value 0.007), severe intraplaque inflammation (p-value 0.017), severe adventitial inflammation (p-value 0.021) and an increased vasa vasorum (p-value 0.012). A significant correlation (p-value 0.002) was observed between the presence of SC at radiological examination and the presence of punctuate/fragmented calcification at histology. In addition, in 58.3% of cases, plaque enhancement was observed, which correlated with plaque inflammation and the fibrolipid composition of the plaque. The coronary artery calcium score was 314 (± 455). There was a poor agreement between stenosis of the lumen at histology versus radiology. Our study shows that the various radiological signs of HRP can be detected in all plaques by MPMCTA, but individually only to a variable extent; plaque enhancement appeared as a new sign of vulnerability. In the postmortem approach, these radiological markers of HRP, should always be applied in combination, which can be useful for developing a predictive model for diagnosing coronary SCD.
Inhibition of viral entry and thereby spread constitute plausible therapeutic avenues. Similar to other respiratory pathogens, SARS-CoV2 is transmitted through respiratory droplets, with potential for aerosol and contact spread. It uses receptor-mediated entry into the human host via angiotensin-converting enzyme II (ACE2) that is expressed in lung tissue, as well as oral and nasal mucosa. Modulation of ACE2 levels in these gateway tissues may prove a plausible strategy for decreasing disease susceptibility. Cannabis sativa, especially one high in the anti-inflammatory cannabinoid cannabidiol (CBD), has been proposed to modulate gene expression and inflammation and possess anti-cancer and anti-inflammatory properties. Covid-19 infection rates in cannabis users will be compared to rates in the general population. Severity of persistent symptoms in cannabis users testing positive for active infection and/or antibodies will also be compared to the general population.
Combat Veterans with posttraumatic stress disorder (PTSD) often show cognitive impairments in attention, working memory, executive functions, and inhibitory control, a cluster of symptoms resembling symptoms of ADHD. The presence of comorbid ADHD cognitive symptoms is often associated with greater PTSD clinical severity and poorer treatment outcomes. While treatments for the avoidance, arousal, and re-experiencing symptoms associated with PTSD for military personnel are readily available, substantial gaps exist in the treatment of the cognitive deficits associated with PTSD. As a result, untreated co-occurring ADHD cognitive symptoms in PTSD may have severe negative impacts on patients' functional recovery, treatment outcome, and quality of life. The proposed study directly addresses this knowledge gap by testing the feasibility and preliminary efficacy of atomoxetine (ATX) in treatment of ADHD cognitive symptoms among those with comorbid ADHD/PTSD. This is a small prospective, 10-week, fixed-dose, randomized, double-blind, placebo-controlled, and cross-over trial of ATX as an add-on medication to other therapies in Veterans with comorbid ADHD/PTSD. Primary outcome measures will be ADHD cognitive symptom reduction and quality of life improvement as measured by the Adult ADHD Rating Scales-Self-Report: Short Version (CAARS-S:S) and the Adult ADHD Quality of Life-29 (AAQoL-29). Secondary outcome measures will be PTSD and depressive symptoms reduction as measured by the Clinician Administered PTSD Scale (CAPS), the Hamilton Depression Scale (HAM-D). In addition to subjective measures, the response inhibition task Go/NoGo (GNG) will be used as objective assessments to measure ATX treatment outcomes. The proposed work is innovative; it applies novel therapeutic agent to treat cognitive symptoms in PTSD. To our knowledge, this is the first study to apply a SNRI to address an often overlooked PTSD-cognitive deficit. This study is directly responsive to the mission of RR\&D-SPiRE "to maximize functional recovery" of cognitive function in PTSD. The outcome of the proposed research will be significant, because it provides a knowledge base to help determine who is at risk for developing treatment resistance among PTSD patients, thereby allowing for development of early intervention strategies. More importantly, this clinical trial may immediate benefit Veterans by enhancing their cognitive function, reducing ADHD symptoms related disability, and further improving quality of life for veterans suffer from comorbid ADHD/PTSD.

Over the years, the neuroprotective potential of bone marrow mesenchymal stem cells (BMSCs) in acute ischemic stroke has attracted significant attention. However, BMSCs face challenges like short metabolic cycles and low survival rates post-transplant. Polypyrimidine tract-binding protein 1 (PTBP1) is an immunomodulatory RNA-binding protein that regulates the cell cycle and increases cell viability. This study investigated the protective effects and underlying mechanism of PTBP1 knockdown in BMSCs (PTBP1KD-BMSCs) following ischemia-reperfusion injury (IRI) in neurons. BMSCs were isolated from Sprague-Dawley rat femurs and characterized through flow cytometry and differentiation induction. PTBP1 knockdown inhibited BMSCs proliferation. Co-culture with PTBP1KD-BMSCs decreased reactive oxygen species (ROS) and malondialdehyde (MDA) levels, while increasing glutathione (GSH) production in oxygen and glucose deprivation/reperfusion-induced PC12 cells. Transcriptome sequencing analysis of PC12 cells suggested that the protective effect of PTBP1KD-BMSCs against injury may involve ferroptosis. Furthermore, western blotting showed upregulation of glutathione synthetase (GSS), glutathione peroxidase 4 (GPX4), and solute carrier family 7 member 11 (SLC7A11) in PTBP1KD-BMSCs, known negative regulators of ferroptosis. Moreover, PTBP1KD-BMSCs inhibited p38MAPK and JNK activation. In addition, PTBP1KD-BMSCs transplantation into middle cerebral artery occlusion/reperfusion (MCAO/R) rats reduced cerebral infarction volume and improved neurological function. Immunofluorescence analysis confirmed the upregulation of GSS expression in neurons of the ischemic cortex, while immunohistochemistry indicated a downregulation of p-P38. These result suggest that PTBP1KD-BMSCs can alleviate neuronal IRI by reducing oxidative stress, inhibiting ferroptosis, and modulating the MAPK pathway, providing a theoretical basis for potential treatment strategies for cerebral IRI.
PURPOSE:To achieve a higher bone deriving capacity and a higher growing effect of a bone by remaking a composition obtained by decalcifying a tooth removed from a human being to a decalcified tooth material in the form of coarse particle of flake to be applied for lost bone or the like as caused by pustule of a jaw bone and pyorrhea. CONSTITUTION:A tooth 1 removed from a human being is washed with a sterilizing liquid to be immersed into an aqueous 0.6N hydrochloric acid solution for three to five days and after the removal of calcium components contained, it is immersed into a sterilizing liquid 3 for a half day to wash. Thus, a first intermediate product 4 is obtained. Then, the first intermediate product 4 obtained is divided into four pieces 4a, 4a... vertically with a razor blade sterilized in a clean bench to remove a dental pulp and then, cut into pieces in 1/2mm squares to obtain a second intermediate product 5. Moreover, the second intermediate product 5 is crushed with a pestle 7 in a mortar 6 both being sterilized into coarse particles with a diameter thereof 0.05-0.3mm. Here, the crushing is performed adding a sterilizing liquid to prevent a rise in heat. Finally, the coarse particles are held into a small resin bottle 8 disinfected and further, placed into a sterilized bag to freeze dry and preserved being frozen.
Baxdrostat is a selective small-molecule aldosterone synthase inhibitor in development for treatment of hypertension and chronic kidney disease. This phase 1, open-label, parallel-group study assessed the safety and pharmacokinetics (PK) of baxdrostat in participants with varying degrees of renal function. Participants were enrolled into control (estimated glomerular filtration rate [eGFR] ≥60 mL/min), moderate to severe renal impairment (eGFR 15-59 mL/min), or kidney failure (eGFR <15 mL/min) groups and received a single 10-mg baxdrostat dose followed by 7 days of inpatient PK blood and urine sampling. Safety was assessed by adverse events, clinical laboratory evaluations, vital signs, physical examinations, and electrocardiograms (ECGs). Thirty-2 participants completed the study. There were no deaths and only 1 mild drug-related adverse event (diarrhea). No clinically meaningful changes in laboratory values, vital signs, physical examinations, or ECGs occurred. Plasma concentration-time curves of baxdrostat were similar among all groups. Urine PK parameters were similar (approximately 12% excreted) in the moderate to severe renal impairment and control groups. Inadequate urine production in the kidney failure group resulted in minimal urinary baxdrostat excretion. Renal impairment had no significant impact on systemic exposure or clearance of baxdrostat, suggesting that dose adjustment due to PK differences in patients with kidney disease is unnecessary.
