This is a system for disseminating obituaries by a depository that monitors reports of death and selectively transmits some of them to persons who have contracted beforehand with the depository to be notified of certain deaths when report of them is received. The depository creates a database of persons whose deaths are to be reported to customers and a database of customers who are to have certain deaths reported to them. The customer specifies the method of communication and the address to which the death notice is to be sent. The depository monitors all reports of death arising in a domain predetermined in an agreement with the customer and compares data identifying the reported deceased with data identifying the awaited deceased selected by customers. When there is a match the depository transmits a notice of death to the customer at the address and in the manner specified. Customers concerned with publicizing a death are able to report that death to the depository and designate third parties to whom a notice of death or memorial services shall be transmitted. A funeral home using the system departs from its conventional role as a funnel through which material for death notices is channeled to newspapers, opens a new route for the dissemination of obituaries and, in solving the problem attending the direct personal notification of marginal acquaintances, creates a practical option of newspaper bypass.
The invention relates to 5-fluorouracil drug-loading microspheres and a preparation method thereof. The invention especially relates to bio-degradable high-molecular-material-coated 5-fluorouracil drug-loading microspheres and a preparation method thereof. According to the preparation method, alpha-cyanoacrylate is adopted as a carrier, and 5-fluorouracil is embedded during an alpha-cyanoacrylate monomer polymerization process, such that drug-loading microspheres with an average particle size of 200nm-5mum are obtained, wherein the mass ratio of 5-fluorouracil to alpha-cyanoacrylate is 1/100-50/100. The invention aims at overcoming defects of existing 5-fluorouracil drug-loading microspheres and preparation methods thereof, and at providing a sustained-release preparation which can be used on surgical wounds and in epidermal administrations. With the cooperation of biological glue in surgical sutures in body cavity or on body surface, degradation speed consistency can be provided. The operation is simple. According to the invention, various other additives such as organic solvents, surfactants, and excipients are not needed.
BACKGROUND: Local anaesthesia in dental procedures is generally safe, although the occurrence of transient bradycardia (TB) has occasionally been reported. TB is often associated with two reflexes, the trigeminal cardiac reflex (TCR) and the vasovagal reflex (VVR) and is characterised by a rapid decrease in heart rate (HR) and blood pressure (BP). The prevalence of TCR is considered low, and its predictors have not been thoroughly investigated, although an association with the gag reflex has been suggested in recent years.
METHODS: This prospective study assessed TB occurrence during local anaesthesia and its potential associated factors. A comprehensive questionnaire was used to categorise discomforts during dental treatment, and various anxiety scales were used to measure patients' anxiety levels. We investigated HR variability during local anaesthesia administration under sedation and the association between the incidence of TB and gag reflex. Subsequently, logistic regression analysis was performed to assess factors associated with TB occurrence.
RESULTS: The prospective analysis included 188 patients of 234 initial patients. The analysis revealed a high TB incidence rate of 41% during local anaesthesia administration under sedation. No severe hypotensive events occurred, indicating a relatively benign nature of TB during local anaesthesia. TB occurrence was significantly higher in the group of patients with the gag reflex. Further analysis revealed that both gag reflex and trait anxiety were significantly associated with TB occurrence, whereas dental phobia did not directly correlate with TB.
CONCLUSION: This study highlights the prominent occurrence of TB during local anaesthesia in dental treatment, which is primarily attributed to TCR activation. The identification of gag reflex and trait anxiety as independent factors associated with TB development may pave the way for TB prevention measures. Further research is required to clarify the mechanisms of TCR and perform safer dental procedures under sedation. Future studies should also aim to elucidate the precise mechanisms underlying TB during local anaesthesia through direct measurements of neural activity. A better understanding of TB in dentistry is crucial for improving patient safety and optimising dental practice protocols.
INTRODUCTION: Oxidant stress, abnormal angiogenesis, and inflammation are three key factors contributing to the development of ocular neovascular diseases (ONDs). This study aims to develop a multifunctional nanodrug, DEX@MPDA-Arg@Si (DMAS), which integrates mesoporous polydopamine, vascular endothelial growth factor (VEGF)-siRNA, and dexamethasone (DEX) to address these therapeutic targets.
METHODS: Physicochemical properties of DMAS were measured using transmission electron microscopy and a nanoparticle size analyzer. The encapsulation efficiency and drug loading capacity of DMAS were measured using a UV-visible spectrophotometer. The in vivo therapeutic efficacy and ocular safety of DMAS were evaluated using three established mouse models, including the alkali burn-induced corneal neovascularization (CoNV) model, the oxygen-induced retinopathy (OIR) model, and the laser-induced choroidal neovascularization (CNV) model.
RESULTS: The DMAS nanoparticles demonstrated a uniform bowl-like shape with an average size of 264.9 ± 2.5 nm and a zeta potential of -28.2 ± 4.2 mV. They exhibited high drug-loading efficiency (36.04 ± 3.60% for DEX) and excellent biocompatibility. In vitro studies confirmed its potent antioxidant, anti-inflammatory, and anti-apoptotic properties. In vivo, DMAS treatment led to significant therapeutic effects across all models. It effectively inhibited CoNV, promoted corneal repair, and modulated inflammation in the alkali burn model. In the OIR model, DMAS reduced retinal neovascularization by decreasing VEGF expression. In the laser-induced CNV model, it significantly reduced the CNV area and lesion thickness.
CONCLUSION: This research developed a multifunctional nanodrug, DMAS, capable of co-delivering VEGF-siRNA and DEX, offering synergistic therapeutic benefits for treating ONDs. The DMAS nanodrug demonstrates promising anti-inflammatory, antioxidative, and anti-angiogenic effects, highlighting its potential as a versatile and effective treatment for multiple ocular conditions.
Cardiovascular magnetic resonance (CMR) is a proven imaging modality for informing diagnosis and prognosis, guiding therapeutic decisions, and risk stratifying surgical intervention. Patients with a cardiac implantable electronic device (CIED) would be expected to derive particular benefit from CMR given high prevalence of cardiomyopathy and arrhythmia. While several guidelines have been published over the last 16 years, it is important to recognize that both the CIED and CMR technologies, as well as our knowledge in MR safety, have evolved rapidly during that period. Given increasing utilization of CIED over the past decades, there is an unmet need to establish a consensus statement that integrates latest evidence concerning MR safety and CIED and CMR technologies. While experienced centers currently perform CMR in CIED patients, broad availability of CMR in this population is lacking, partially due to limited availability of resources for programming devices and appropriate monitoring, but also related to knowledge gaps regarding the risk-benefit ratio of CMR in this growing population. To address the knowledge gaps, this SCMR Expert Consensus Statement integrates consensus guidelines, primary data, and opinions from experts across disparate fields towards the shared goal of informing evidenced-based decision-making regarding the risk-benefit ratio of CMR for patients with CIEDs.
BACKGROUND: Inadequately treated postoperative pain following caesarean delivery can delay recovery and the ability to care for a newborn. Effectiveness studies of interventions to treat postoperative caesarean delivery pain measure different outcomes, limiting data pooling for meta-analysis. We performed a comprehensive review of existing outcomes with the aim of recommending core outcomes for future research.
METHODS: A scoping review to identify all outcomes reported in randomised controlled trials (RCTs) and clinical trial registries of interventions to treat or prevent postoperative caesarean delivery pain, with postoperative pain as a primary outcome measure. We searched PubMed, Web of Science, CINAHL, LILACS, Embase, CDSR and CRCT for studies from May 2016 to 2021. Outcomes were extracted and frequencies tabulated.
RESULTS: Ninety RCTs and 11 trial registries were included. In total, 392 outcomes (375 inpatient and 17 outpatient) were identified and categorised. The most reported outcome domain was analgesia (n = 242/375, 64.5%), reported in 96% of inpatient studies, with analgesic consumption accounting for 108/375, 28.8% of analgesia outcomes. The second most common domain was pain intensity (n = 120/375, 32%), reported in 97% of inpatient studies, using the visual analogue scale (68/120, 59%) and the numerical reporting scale (37/120, 25%). Maternal and neonatal adverse effects accounted for 65/375 (17.3%) and 19/375 (5.1%) of inpatient outcomes, respectively.
CONCLUSIONS: Outcomes reported in RCTs for postoperative caesarean delivery pain vary widely. The results of this review suggest that standardisation is needed to promote research efficiency and aid future meta-analyses to identify optimal postoperative caesarean delivery pain management.

The present invention is drawn to a composition of matter comprising high viscosity sodium alginate, cellulose sulfate and a multi-component polycation. Additionally, the present invention provides methods for making capsules, measuring capsule permeability to immunologically-relevant proteins and treating disease in an animal using encapsulated cells. Over one thousand combinations of polyanions and polycations were examined as polymer candidates suitable for encapsulation of living cells and thirty-three pairs were effective. The combination of sodium alginate, cellulose sulfate, poly(methylene-co-guanidine) hydrochloride, calcium chloride, and sodium chloride produced the most desirable results. Pancreatic islets encapsulated in this multicomponent capsule demonstrated glucose-stimulated insulin secretion in vitro and reversed diabetes without stimulating immune reaction in mice. The capsule formulation and system of the present invention allows independent adjustments of capsule size, wall thickness, mechanical strength and permeability, and offers distinct advantages for immunoisolating cells.

In order to distribute a radioactive halogen isotope uniformly in an oil, an aqueous solution containing a compound of the isotope is mixed with an unsaturated oil or an oil containing unsaturated compounds and water is expelled from the mixture by heating to above the boiling point of water but below the boiling point of the oil. Suitable oils are cod-liver, lard, sperm, olive, castor and cottonseed oils, crude petroleum oil and its unsaturated fractions, and mineral lubricating and cutting oils; waxes liquefiable by heat may also be used.  Heating may take place at 120 DEG  C. for 4 hours. In Example (1), radioactive iodine, in the form of sodium iodide dissolved in a basic aqueous solution of sodium sulphite, is dispersed in crude petroleum oil; the composition is used for testing the residue of crude oil left in oil well cores after processing to remove the oil.  In Example (2), radioactive iodine is similarly dispersed in mineral lubricating oil and the composition is used for testing the amount of residual machine oil left on metal parts after a cleaning process.  Specification 795,028 is referred to.
OBJECTIVES: Previous studies have identified abnormal expression of lncRNA SNHG12 in ischemic stroke, but the underlying molecular mechanism remains unclear.
MATERIALS AND METHODS: Through database predictions, m6A methylation sites were found on SNHG12, suggesting post-transcriptional modification. To further elucidate the role of SNHG12 and m6A methyltransferase WTAP in oxygen-glucose deprivation/reperfusion (OGD/R)-induced damage in cerebral microvascular endothelial cells, we conducted investigations. Additionally, we examined the impact of m6A methyltransferase WTAP on SNHG12 expression.
RESULTS: Overexpressing SNHG12 in bEnd.3 cells was found to inhibit cell proliferation and promote apoptosis, as well as activate the production of reactive oxygen species and inflammatory cytokines (E-selectin, IL-6 and MCP-1), along with angiogenic proteins (VEGFA and FGFb). Conversely, SNHG12 knockdown alleviated OGD/R-induced damage to BEnd.3 cells, resulting in improved cell proliferation, reduced apoptosis, decreased ROS and LDH production, as well as diminished expression of inflammatory cytokines (E-selectin, IL-6 and MCP-1) and angiogenic proteins (VEGFA and FGFb). Furthermore, WTAP was found to positively regulate SNHG12 expression, and WTAP knockdown in bEnd.3 cells under the OGD/R conditions inhibited cell proliferation, promoted apoptosis, and increased ROS and LDH production.
CONCLUSION: These findings suggest that WTAP may play a crucial role in SNHG12-mediated OGD/R-induced damage in bEnd.3 cells. More molecular experiments are needed to further analyze its mechanism. Overall, our study helps to enrich our understanding of the dysregulation of SNHG12 in ischemic stroke.
Soft implantable devices are crucial to optimizing form and function for many patients. However, periprosthetic capsule fibrosis is one of the major challenges limiting the use of implants. Currently, little is understood about how spatial and temporal factors influence capsule physiology and how the local capsule environment affects the implant structure. In this work, we analyzed breast implant capsule specimens with staining, immunohistochemistry, and real-time polymerase chain reaction to investigate spatiotemporal differences in inflammation and fibrosis. We demonstrated that in comparison to the anterior capsule against the convex surface of breast implants, the posterior capsule against the flat surface of the breast implant displays several features of a dysregulated foreign body reaction including increased capsule thickness, abnormal extracellular remodeling, and infiltration of macrophages. Furthermore, the expression of pro-inflammatory cytokines increased in the posterior capsule across the lifespan of the device, but not in the anterior capsule. We also analyzed the surface oxidation of breast explant samples with XPS analysis. No significant differences in surface oxidation were identified either spatially or temporally. Collectively, our results support spatiotemporal heterogeneity in inflammation and fibrosis within the breast implant capsule. These findings presented here provide a more detailed picture of the complexity of the foreign body reaction surrounding implants destined for human use and could lead to key research avenues and clinical applications to treat periprosthetic fibrosis and improve device longevity.
Liver cancer is the sixth most common cancer and the third leading cause of death from cancer worldwide (source: Globocan 2018). Hepatocellular carcinoma (HCC) represents 80-90% of liver cancers. Percutaneous thermal ablation (PTA) is a validated treatment option for very early and early stage HCC, together with surgical resection and liver transplantation (EASL Clinical Practice Guidelines: Management of hepatocellular carcinoma, J Hepatol 2018). Due to its excellent tolerance, particularly in patients with portal hypertension or bearing comorbidities, it now represents in France nearly 70% of the first-line curative treatment of "in Milan" tumours. The risk of local tumor progression (LTP) is ≈10-20% in PTA series (Nault, J Hepatol 2018; N'Kontchou et al., Hepatology (Baltimore, Md) 2009). In addition, the long-term results of PTA are influenced by the high rate (up to 60-80% at 5 years) of intrahepatic distant recurrence (IDR) (Nault et al., J Hepatol 2018), as observed also after HCC surgical resection (EASL Clinical Practice Guidelines: Management of hepatocellular carcinoma, J Hepatol 2018; Imamura et al., J Hepatol 2003). It is unknown whether early IDR (2-3 years after PTA of \<3 cm HCC) is due to metastatic spread or de novo carcinogenesis.

Strong scientific rationale and emerging clinical data suggest that the combined vascular endothelial growth factor (VEGF) / Programmed death-ligand 1 (PD-L1) blockade may be clinically beneficial in a number of tumor types, including HCC. Therefore, local ablation in HCC is an " ideal " context to test Atezolizumab + Bevacizumab in combination with ablation. The investigators hypothesized that the combo of Atezolizumab + Bevacizumab and radiofrequency ablation could improve recurrence-free survival (RFS) at 2 years.

The aim of this randomized multicentre phase II trial is to compare RFS at 2 years in the experimental arm (Atezolizumab + Bevacizumab + RF ablation) versus the control arm (RF ablation) according to HCC modified response evaluation criteria in solid tumours (mRECIST). Thus the proposed use here of Atezolizumab as first neoadjuvant, then in combination with Bevacizumab as adjuvants, should theoretically, and hopefully, limit the radiofrequency ablation (RFA) pro-tumor effects. The RFS current rate value of 45% corresponding to the standard procedure of RFA alone (i.e. in the Active Comparator arm) should be increasing to at least 65% because of the addition of the biotherapy (i.e. in the Experimental arm). The patients' recruitment timeframe is set at 36 months and the patient's follow-up timeframe is 5 years. 202 patients are to be included, 101 per arm.
After completing screening, 30 subjects in the sarcopenia group received a 3-month intensive intervention consisting of an intensive nutritional intervention and an individually designed exercise intervention. Nutritional and exercise prescriptions were co-designed through a nutritionist and rehabilitation physician.
PURPOSE:To accurately determine a bone salt and to have the energy dependency approximate to the energy dependency of a vital bone as well as to eliminate the need for calibrating the device by dispersing a calcium phosphate compd. as the material equiv. to the bone salt into a high-polymer compd. CONSTITUTION:The phantom for determination of the bone salt is prepd. by dispersing the calcium phosphate compd. as the material equiv. to the bone salt into the high-polymer compd. Various kinds of thermoplastic resins or high-polymer materials soluble in water or org. solvents are used as the high polymer compd. One or >=2 kinds of hydroxyapatite, tricalcium phosphate and tetracalcium phosphate are used as the calcium phosphate compd. The phantom for determination of the bone salt is produced by, for example, dispersing the calcium phosphate into a prepolymer having the flowability of the high-polymer compd., then progressing the polymn. reaction to cure the polymer.
In these 2 populations of patients, more malabsorptive procedures like long limb One Anastomosis Gastric Bypass or Bilio-Pancreatic Diversion with Duodenal Switch could be more efficient but induce technical difficulties (high complication rate) and can be responsible for malnutrition (vitamin deficiencies, hypoalbuminemia...). That's why, in case of revisional surgery or for high BMI patients,laparoscopic Roux-en-Y gastric bypass (RYGBP) is still considered as the gold standard and is the most performed intervention. To obtain better weight loss safely,Santoro et al. promoted the sleeve gastrectomy with transit bipartition (SG+TB), a new intervention coupling a SG without interrupting pathway through the duodenum and preserving the pylorus and a long biliary limb RYGBP.

Hypothesis: Because there is no duodenal and jejunal exclusion, malnutrition is expected to be less frequent after SG+TB compared to BPD/DS. Its anastomosis on the antrum makes SG+TB easier to perform in super-obese patient than standard RYGB but more efficient in term of weight loss. Compared to BPD/DS or SADI which involves dissection of the duodenum and the confection of a duodenojejunostomy, SG+TB is also expected to be easier then safer.
