Background: Increasing costs and complexity in clinical trials requires recruitment of more narrowly defined patient populations. However, recruitment for clinical trials remains a considerable challenge. Aim: Our overall aim was to quantify recruitment performance in industry-sponsored phase III clinical trials conducted globally during 2008-2019 with primary aim to examine development of overall clinical trial measures (number of trials completed, number of participants enrolled, trial duration in months) and key recruitment metrics (recruitment rate, number of sites, number of patients enrolled per site). Methods: The publicly available AACT database containing data on all trials registered at ClinicalTrials.gov since 2008 was used. The analysis was completed during three time periods from 2008-2019 of 4 years each. Results and conclusion: Recruitment duration for industry-sponsored phase III clinical trials have increased significantly during the last 12 years from an average recruitment period of 13 months (IQR 7-23) in 2008-2011 to 18 months (IQR 11-28) in 2016-2019 (p = 0.0068). Further, phase III clinical trials have increased the number of registered sites per clinical trial by more than 30% during the last 12 years from a median number 43 sites (IQR 17-84) in 2012-2015 to 64 sites (IQR 30-118) in 2016-2019 (p = 0.025), and concurrently, the number of participants enrolled in clinical research has decreased significantly from 2012-2015 and 2016-2019 (p = 0.046). We believe that these findings indicate that recruitment for phase III clinical trials is less effective today compared to 12 years ago.

Key Points • CRP reduction at day five of more than 35% from the previous highest concentration post-laryngectomy or laryngopharyngectomy has been proposed to positively predict healing without pharyngocutaneous fistula • Retrospective cohort analysis of 163 patients has not been able to externally validate these findings. • ROC curves and subset analyses have not identified alternative parameters to reach significance • However, there is a non-significant association with decreasing postoperative CRP and healing without fistula. • Multicentre prospective studies to include post-operative procalcitonin could help refine this protocol further.

Introduction Recent guidelines suggest obstructive sleep apnoea (OSA) is not an absolute contraindication for same day discharge following surgery. The aim of this systematic review was to examine the feasibility and safety of day case nasal and/or palatopharyngeal surgery in patients with OSA. Methods We performed a systematic search of PubMed, EMBASE and the Cochrane library. Quality assessment of included studies was done. The protocol of this systematic review was registered with PROSPERO (CRD42021273451). Results A total of 1836 patients from ten observational studies were included. There were 268 (15.4%) nasal surgeries, 738 palatopharyngeal surgeries (42.4%) and 735 (42.2%) combined nasal and palatopharyngeal surgery. The majority of patients had moderate to severe OSA. A total of 860 patients (49.8%) were successfully discharged as day cases. There were no standard criteria for daycase surgery. Post-anaesthetic respiratory events were reported in 86/1750 (4.9%) patients. Oxygen desaturation was the most common respiratory event (83.7%, n = 72). There was no mortality reported. Conclusion Current data suggests day surgery is feasible in carefully selected patients with OSA undergoing nasal and/or palatopharyngeal surgery. Further well-designed prospective studies with an emphasis on the systematic assessment of complications are required to establish safety and daycase criteria.

The COVID-19 pandemic is still continuing. Current major variants of SARS-CoV-2 (Delta and Omicron) have lead to new uncertainties. Since the infection of SARS-CoV-2 and its major variants has been a high risk factor of cardiovascular health due to major adverse cardiovascular events (MACCE) and outcomes. Thus, the more coverage of vaccination, enough health workers, and related medical resources as well as the “ISISI” barriers from locals or regions to the globe play a critical role in combating COVID-19 and protection of human cardiovascular health.

Fluvoxamine is a selective-serotonin reuptake inhibitor (SSRI), well-tolerated and widely available, usually used in the management of mental-health conditions. Fluvoxamine is also a sigma-1 agonist with high affinity to this receptor and this pharmacodynamical effect has been being portrayed as the main explanation in emerging evidence about the potential of using fluvoxamine in COVID-19 patients. This systematic review was conducted according to the PRISMA guidelines. The search was run in MEDLINE, Web of Science, and CENTRAL from the Cochrane databases. The study protocol was registered in PROSPERO (CRD42022302025). Our aim was to assess the present evidence for therapeutic role of fluvoxamine in COVID-19 patients, the review included studies which evaluate the effect of fluvoxamine in COVID-19 patients. The main outcomes evaluated in the review were: mortality, need for hospitalization (outpatients) and clinical deterioration. The quality control of the selected articles was made using Cochrane’s Risk of Bias tool for the randomized controlled trials (RCTs) and the ROBINS-I criteria for non-randomized studies. A total of 4 studies were included in the final qualitative analysis of the review, 2 of which were RCTs, and the others were open-label prospective cohorts. 3 studies assessed outpatient population and 1 evaluated ICU population. Overall, the 4 studies included a total of 1864 participants. In conclusion, 3 studies with outpatients showed that fluvoxamine treatment can prevent clinical deterioration, hospitalisation, or proxy-hospitalisation. The only study with patients hospitalized in the ICU also demonstrated a therapeutic benefit reducing overall mortality.

Many cases of VZV reactivation after mRNA and inactivated COVID-19 vaccine have been reported in the litterature We report a case of an herpes zoster involving the maxillary nerve in a 66 year-old immunocompetent female, that appeared 5 days after the first dose of a viral vector COVID-19 vaccination, with a favourable outcome.

Insulin resistance and progressive decline in functional β-cell mass are two key factors for developing T2D, which is largely driven by overweight and obesity, a significant obstacle for effective metabolic control in many patients with T2D. Thus, agents that simultaneously ameliorate obesity and promote insulin sensitivity and β-cell function could be more effective for treating T2D. Here, we report that elenolic acid (EA), a small molecule, is such a dual-action agent. Oral administration of EA restored glucose homeostasis and other metabolic disorders in diet-induced obese mice, which were associated with increased circulating GLP-1, PYY, and GIP concentrations. EA slowed gastric emptying, downregulated hypothalamic agouti-related peptide, and reduced food intake and obesity in obese mice. EA also exerted potent anti-hyperglycemic effect in db/db mice that was comparable to that of liraglutide but greater than that of metformin, and it was more effective in promoting weight loss relative to these two drugs. Mechanistically, EA directly stimulated GLP-1 and PYY secretion from L-cells, and its induction of GLP-1 release is mediated via Gαq/phospholipase C-mediated pathway. EA also directly suppresses glucose production in liver cells. These results suggest that EA is a novel, dual-action agent for developing drug to treat both T2D and obesity.

Neonatal lupus erythematosus (NLE) is a rare autoimmune disease due to a passive transfer of maternal autoantibodies to the fetus. Clinical spectrum is variable and includes skin lesions, cardiac, hematological, or hepatobiliary disorders. We report a NLE case presenting with skin eruption that was initially considered as tinea.

We report a unique case of self-healing collodion baby (CB) that was successfully managed despite the risk of potentially serious complications. Self-healing CB is a rare and distinct outcome of collodion phenotype occurring in approximately 10% of the cases. The outcome depends on the initial assessment and adequate multidisciplinary approach.

Flesh lignification is a typical chilling injury (CI) symptom of loquat fruit during cold storage. [Calcium](D:/D%E7%9B%98/Youdao/Dict/8.9.9.0/resultui/html/index.html) [chloride](D:/D%E7%9B%98/Youdao/Dict/8.9.9.0/resultui/html/index.html) (CaCl 2) could enhance chilling tolerance in loquat fruit, but the molecular mechanism is still not illuminated. In this study, CaCl 2 treatment suppressed the increase in firmness and lignin content, and retained higher extractable juice, thereby alleviating chilling-induced lignification in loquat fruit. Moreover, CaCl 2 enhanced the [calmodulin](javascript:;) (CaM) content, free Ca 2+ distribution, EjCaM7, and CaM binding transcription activators 3 ( EjCAMTA3) expression in loquat fruit during cold storage, indicating Ca 2+/CaM-CAMTA played a key role in response to cold stress. The EjCAMTA3 and EjCaM7 proteins were identified and characterized from loquat fruit. Importantly, EjCAMTA3 bound to the CG-box in EjPODP7-like and EjLAC12-like promoters to repress their transcription. Further analysis revealed that EjCaM7 interacted with EjCAMTA3 in a Ca 2+-dependent manner, and this interaction enhanced the EjCAMTA3-mediated transcriptional repression of EjPODP7-like and EjLAC12-like genes. Taken together, these findings suggested that CaCl 2 treatment alleviates chilling-induced lignification in loquat fruit, which probably via the synergistic role of EjCaM7 and EjCAMTA3 in the modulation of EjPODP7-like and EjLAC12-like genes expression, leading to the repression of lignin polymerization.

Zinc is an essential minor element for the rice growth and the human health. Applying Zn fertilizer to rice ( Oryza sativa L.) is an effective way to boost yield and grain zinc content. As the most active component in soil, microorganisms can realize a virtuous cycle of soil nutrients and crop growth. However, current studies on the impacts of Zn fertilizer application on crop yield and grain Zn content are inconsistent. The mechanism during the process, especially concerning the soil bacterial community characteristics, is yet unclear. Therefore, it’s important to have a comprehensive understanding of the rice rhizosphere bacterial communities. We took advantage of 16S rRNA gene sequencing and co-occurrence network analysis to study the effects of Zn fertilizer application on the rice grain yield, Zn content and the soil bacterial community. Results showed that Zn application (ZS2, i.e., 10.35 kg ha -1 Zn soil application + 3.10 kg ha -1 foliar spraying) increased the grain yield (17.34%~19.52%) and enriched the Zn content of polished rice (1.40%~20.05%) compared with the control group (ZS0) treatments. This was closely correlated to the soil available Zn (AZ) contents (1.16%~85.69%). Furthermore, soil total nitrogen (TN) was considered as the primary driver which led to a community shift in the rice rhizosphere bacterial community. This was mainly due to the variation in the co-occurrence network which made more complex and stable caused by the Zn fertilizer application. Thus, the interaction between different species was strengthened. During the process, the most critical bacteria taxa were identified as Actinobacteria, Bacteroidetes, Proteobacteria, and Chloroflexi. KEGG metabolic pathway prediction demonstrated that Zn application may improve metabolism functions such as lipid metabolism, amino acid metabolism, carbohydrate metabolism, and xenobiotics biodegradation, which ultimately affected the yield and Zn content of rice grains. However, their positive effects were different among rice cultivars, of which Nanjing-9108 performed better. This study deepens the understanding of the interaction between Zn fertilizer, rice yield, Zn content of rice grain, and soil bacterial structure and further navigates the development of Zn-rich rice cultivation strategies.

Abstract: Objective To analyze the current status, hotspots and frontier trends of genomics research on the outbreak of novel coronavirus disease (COVID-19) from 2019 to the present (March 2022). Methods Using citespace software to conduct statistical and visual analysis of data in each country, institutions, authors, journals, co-cited literature, keywords, etc. were published on the 2019-2022 Web of Science Core Collection Database (WOS) on the genomics of novel coronavirus pneumonia Results of related literature.

Rationale. Influenza is potentially fatal infectious disease that is difficult to both treat and prevent due to the natural range, and unpredictable nature of host immune responses. Studies evaluate immune reaction on quantitative and functional data, but anatomical in only a few cases with histological analysis. Objectives. Could two-photon excitation microscopy (TPEM) improve anatomical description at cell level of pulmonary Influenzavirus infection? Methods. Pulmonary sections from transgenic C57BL/6 mice that had CD11c+ cells expressing yellow fluorescent protein were examined following experimental infection with a red fluorescent protein-expressing Influenza A virus. Measurements. Two-photon lung micrographs were taken on days 1, 2, 3 and 4 post-infections. Flow cytometry analysis and whole-lung cytokine assays were also performed at the same post-infections time points. Results. TPEM showed how the infection resulted in bronchial and bronchiolar epithelial destruction. Initially located in the bronchial and bronchiolar epithelium, virus diffused homogeneously into the alveolar compartment. In response, the host secreted proinflammatory cytokines and rapidly recruited macrophages into the lungs from the perivascular compartment. On day 4 post infection, macrophages were homogeneously distributed throughout the entire pulmonary parenchyma, starting to scavenge cellular debris. Three-dimensional reconstructions of TPEM images provided quantifiable map that traced infection through the lungs. Conclusions. This study demonstrated the added value of using TPEM to map pulmonary viral infections, epithelial lesions, macrophages recruitment and cellular interactions with more precision than histological analysis. Finally, TPEM coupled to cytometry could provide a more precise picture of the cell interactions after a lung infection by influenza virus.

Background Laser balloon ablation (LBA) is a balloon-based catheter ablation technology used for atrial fibrillation (AF) ablation in recent years. The laser balloon has the potential to extend the isolation area because of its changeable balloon size. The purpose of the study was to investigate the feasibility and safety of extended LBA technique, and to compare the isolation area with an established balloon technique using the cryoballoon ablation (CBA). Methods From June 2020 to July 2021, 76 consecutive patients with paroxysmal AF who underwent initial pulmonary vein isolation were enrolled. Of these, 65 patients were included in the study, excluding 11 who met the exclusion criteria; 32 and 33 patients were in the LBA and CBA groups, respectively. In the LBA group, after standard ablation of each PV, additional extended posterior wall ablation was performed by increasing the balloon size to the maximum (the extended LBA technique). In the CBA group, cryoablation was performed using a 28-mm balloon. In both groups, voltage maps were created for measuring the isolated surface area (ISA) by the CARTO mapping system pre- and post-ablation. Results In the LBA group, the extended LBA technique was feasible in all patients. The total ISA after the extended LBA technique was significantly larger than before (32.4±6.5 vs 22.3±4.1 cm 2, p<0.001) and the non-isolated posterior wall area was significantly smaller (8.9 ± 3.5 vs 13.3 ± 3.7 cm2, p<0.001). Although the percentage of esophageal temperature elevation (>39.0°C) was higher during the extended LBA than during the standard LBA (LIPV: 26/32 [81%] vs. 7/32 [22%], p<0.001; LSPV: 10/32 [31%] vs. 2/32 [6%], p<0.001), symptomatic gastric hypomotility or esophageal mucosal injury was not observed in all patients. Comparing the extended LBA and the CBA group, IASA-R (18.1 ± 4.6 vs 15.9 ± 3.5, p=0.033) and non-isolated posterior wall (8.9 ± 3.5 vs 12.4 ± 3.7, p<0.001) were significantly greater in the extended LBA, but cardiac enzyme elevation after ablation was lower than the CBA group. No significant differences were found between the two groups in perioperative major complications or AF-free survival at 3 and 6 months. Conclusions LBA with extended posterior wall isolation technique was safe and feasible. Long-term effectiveness studies should be evaluated in a larger sample size.

A 68-yr-old lady underwent a VVI pacemaker implantation 10 years back for infra-hisian complete heart block. Now she presents with 3 episodes of syncope within the last 2 months. Detailed neurological evaluation and pacemaker checkup was initially unremarkable. Real time electrograms during device interrogation were suspicious of lead noise resulting in oversensing. She became alright when the pacing mode was made VOO immediately. After discussion with patient relatives she underwent ventricular lead replacement and upgradation to a dual chamber pacemaker. However, in the immediate post-operative period she became unresponsive requiring immediate resuscitation. Monitor suggested short runs of polymorphic VT which was reproducibly suppressed with higher rate obligatory pacing @ 110 bpm. The runs of VT resurfaced immediately as the rate was lower than 90. She was managed by overdrive pacing at a lower rate of 110 bpm. Over the next 2 months the lower rate was brought down to 70 bpm in a stepwise manner. A retrospective analysis of her initial stored device electrogram suggested that it was all PMVT and no noise at all. The cause of her polymorphic VT is not clear. Relative hypomagnesemia, late presenting long QT syndrome and long term VVI pacing in isolation or combination remain the probable offender. She is presently doing well on oral propranolol.

Objectives: Several studies proposed a loss of neural structures in Menière’s disease (MD). It has also been shown that VIIth and VIIIth cranial nerves are enlarged within MD patients compared to normal controls. We aimed to investigate potential differences in these two nerves in patients with MD. Setting: 71 patients with MD were included, 53 showed clinically unilateral affection. Constructive-interference-in-steady-state(CISS) and 3D-FLAIR-inversion-recovery(IR) sequences with two different slice thicknesses were acquired on a clinical 3T magnetic resonance imaging scanner. We evaluated morphometric properties of the VIIth and VIIIth cranial nerves passing from the cerebellopontine angle to the inner ear modiolus. In patients with clinically unilateral MD, we compared the unaffected to the clinically affected side. In addition, we evaluated the morphology of the nerves in correlation to symptom duration. Results: The clinically unilateral MD-patients showed no significant differences after Bonferroni correction when comparing the affected side to the non-affected side of VIIth and VIIIth cranial nerves. There was no significant difference between patients with different symptom durations. Conclusions: Our data showed no differences in nerve morphometry between the clinically non-affected and the clinically affected side in patients with clinically unilateral MD. There was also no correlation to duration of symptoms, in contrast to previously demonstrated correlations between clinical features and the extent of endolymphatic hydrops. A disease process starting before onset of clinical symptoms could be a potential explanation.

Objective. To discuss the presentation, evaluation, and management of congenital laryngeal web. Methods.: The Institutional Board of Ethics of shanghai Children’s Hospital approved this retrospective review of all patients who were diagnosed with laryngeal web at our institution within the past 10 years. Charts mined for age at presentation, presenting symptoms, degree/location of web, associated syndromes, number/type of surgical procedures, and postoperative outcomes. Results.: Ten patients were included (6 male, 4female). There were 3 type I、II webs, 7 type III、IV webs; Children with type I and II laryngeal web were mainly presented with hoarseness and discomfort without any obvious respiratory distress（P＜0.05）. Children were usually older when they were presented to the hospital（p<0.05）, All the 3 children with type I and II laryngeal web recovered after a single endoscopic procedure. While children with laryngeal web type III and IV usually had a record of multiple visits to the hospital with multiple treatments（p<0.05） All of these 7 type III、IV webs , the tracheotomy was performed early, The ultimate treatment required for such patients was open laryngoplasty. Conclusions：There is a need for alertness regarding the neonatus exhibiting hoarseness and weak crying. To achieve a satisfactory outcome, it is essential to perform accurate preoperative staging and assessment along with an appropriate choice of treatment and placement of the laryngeal stent.

Abstract OBJECTIVES Given its rarity and the lack of clear clinical markers, amyotrophic lateral sclerosis (ALS) remains a diagnostic challenge. Since bulbar-onset ALS (buALS) presents with impaired speech or swallowing, patients are often primarily referred to an otolaryngologist (ORL) or phoniatrician. We analyzed the role of such specialists in ALS diagnostics and treatment. PARTICIPANTS We reviewed data for all 327 patients treated for ALS through the Hospital District of Helsinki and Uusimaa (HUS) between 2010 and 2014, focusing specifically on 110 (34%) patients presenting with bulbar nerve onset (buALS). MAIN OUTCOME MEASURES The presenting symptoms, referral to specialized care, and to a neurology clinic were assessed. Indications and findings from swallowing studies were reviewed as well as the incidence of percutaneous endoscopic gastrostomy (PEG) and tracheostomy. RESULTS Among the 110 patients with buALS, 64 (58%) were primarily referred to a neurologist, 28 (25%) to an ORL, and 5 (5%) to a phoniatrician. The most common presenting symptom was dysarthria in 89 patients, (81%), followed by dysphagia in 26 (24%). In most cases, an ORL or phoniatrician suspected a neuromuscular disease; however, in 8 (24%) cases, the neurological etiology of symptoms was missed. Overall, 49 (45%) patients underwent a swallowing study and 86 (78%) patients underwent PEG placement. CONCLUSIONS Among buALS patients, 30% initially consulted an ORL or phoniatrician and 45% underwent a swallowing study. Based on our results, swallowing studies rarely lead to immediate PEG placement. An initial visit to other specialists had no impact on diagnostic delays or survival. Five keypoints Amyotrophic lateral sclerosis (or ALS) Motor neuron disease Dysphagia Fiberoptic Endoscopic Examination of Swallowing (or FEES) Percutaneous Endoscopic Gastrostomy (or PEG) Level of Evidence: 3

Solar energy is basic source of renewable energy, and it is being used for controlling the global pollutions/warming. As cross nanofluid is very useful for upgrading the solar energy systems efficiency so it is engaged for cooling the solar devices. In this paper for analysis of global warming heat equation is modeled by incorporating the nonlinear thermal radiation by using the exponentially extendable surface, because it keeps major role related to solar energy absorption of nanofluid. Furthermore, the mathematical modeling of cross nanofluid involving magnetic effect and diffusion is discussed by using the fact of chemical reaction. Chemical reaction finds astonishing applications regarding pollution studies, chemical processing equipment, polymer production. As a result of this study, it is noticed that more magnetized the conducting fluid controls the motion of fluids for both case of shear thinning and shear thickening. Brownian motion parameter Nb tells the rate the random motion of nanoparticle. Increased Nb temperature is also increases due to these random movement of nanoparticles. That is the reason when pollutant nanoparticles spreading in air as a result global warming increase.

Background and objectives: Inadequate adherence has been recognized as a constant determinant in the overall burden of ischemic heart disease, particularly in countries with higher income-health inequalities, such as Mexico. The overall impression is that the lack of population-based epidemiological data and low public awareness may account for this problem. This study aimed to determine the level of adherence to secondary cardiovascular prevention therapy in a tertiary hospital in Mexico City and identify the barriers contributing to medication nonadherence. Methods: A cross-sectional study was conducted in the cardiology outpatient department between August 2018 and February 2020. Participants were asked about socio-demographic data, the MMAS-4, and an interview regarding reasons for nonadherence. Results: A total of 991 patients were included, with a median age of 65 (58,72) years old. Inadequate adherence to treatment was reported by 70.3%, with forgetfulness as the most frequent cause (55.4%). Patients on combined pharmacological therapy with PCI or CABG were more adherent than those on optimal medical therapy alone. A higher proportion of patients in the inadequate group were in NYHA classes II and III. Low educational level and the use of optimal medical treatment alone were predictors for poor adherence. Conclusion: These findings provide an initial framework of the current situation of adherence to secondary prevention therapy in Mexico, highlighting the value of promoting national consensus on medication adherence to move towards a population-based strategy to reduce cardiovascular disease burden.

Abiotic and biotic factors structure species assembly in ecosystems both horizontally and vertically. However, the way community composition changes along comparable horizontal and vertical distances in complex three-dimensional habitats, and the factors driving these patterns, remain poorly understood. By sampling ant assemblages at comparable vertical and horizontal spatial scales in a tropical rain forest, we compared observed patterns with those predicted according to environmental filtering by microclimate and microhabitat structure. We found that although dissimilarity between ant assemblages increased with vertical distance, the dissimilarity was higher horizontally but was independent of distance. The pronounced horizontal and vertical structuring of ant assemblages across short distances is likely explained by a combination of microclimate and microhabitat connectivity. Our results demonstrate the importance of considering three-dimensional spatial variation in local assemblages and reveal how highly diverse communities can be supported by complex habitats.

A 60-year-old woman with bilateral superficial femoral artery occlusion underwent femoral-popliteal bypass surgery. Six months later, left vascular prosthesis occlusion occurred; 1.5 years later, an occlusive embolus developed in the deep femoral artery. The proximal prosthesis aspect was detached from the native vessel. The limb was salvaged with bypass surgery.

The following case report describes a patient that presented with a dental needle that fractured during an inferior alveolar nerve block.
