Responses of coastal phytoplankton communities to seasonal herbicide inputs: Tolerance or degeneration?

Herbicide-induced phytoplankton inhibition threatens coastal biodiversity and ecosystem function. Although studies employing single-frequence exposure aid in understanding the phytoplankton community's responses to herbicides, it's difficult to objectively assess their response to cyclic herbicide inputs (long-term low-dose and short-term high-dose) in marine ecosystems. Here, we analyzed the concentration and distribution of herbicides in global coastal waters and simulated this cyclic process through a two-phase atrazine exposure mesocosm experiment and laboratory tests. The results indicated that, the herbicide concentrations (0.82 nmol L-1, 95 % CI 0.55, 1.74) from May to August were significantly higher than that (0.14 nmol L-1, 95 % CI 0.02, 0.38) in the remainder months, and highest concentrations typically emerged in summer; the changes in phytoplankton community composition under environmental concentrations of triazine herbicides could recover in the short term, but sustained inhibition of biomass was produced; the dominant populations were more likely to develop tolerance through preexposure and recover from subsequent impulse of atrazine, but this process was accompanied by the loss of rare groups and a decrease in biodiversity, meanwhile, affected the bacterial community in phycosphere. Consequently, we considered that the cyclic herbicide inputs may cause more detrimental effects than single-frequence exposure, potentially leading to a large-scale decline in coastal primary productivity.

Molecular Insight into CO2 Improving Oil Mobility in Shale Inorganic Nanopores Containing Water Films.

CO2 injection into shale reservoirs has been recognized as one of the most promising techniques for enhanced oil recovery and carbon capture, utilization, and storage. However, the omnipresent nanopores and the water films formed near the pore walls affect the understanding of mechanisms of CO2 regulating crude oil mobility in shale nanopores. In this work, we employ molecular dynamics simulations to study the occurrence and flow of CO2 and octane (nC8) mixtures in quartz nanopores containing water films, to illustrate the impact mechanisms of CO2 on nC8 mobility. The results indicate that nC8 exists between water films, and CO2 is mainly miscible with nC8 in the pore center, and a small portion of it accumulates at the interface between nC8 and the water film. CO2 significantly decreases the apparent viscosity of nC8 in both the bulk nC8 region and the nC8-water interface region, improving nC8 fluidity. As the percentage of CO2 in the CO2 and nC8 mixtures increases from 0 to 50%, the mean flow velocities of nC8 in the bulk phase region and the nC8-water interface region increase by 92.85 and 60.64%, respectively. Three major microscopic mechanisms of CO2 improving nC8 fluidity in quartz nanopores with water films are summarized: (i) CO2 reduces friction between nC8 and the water film by increasing the angle between nC8 molecules and the plane of the water film; (ii) CO2 widens the distance between nC8 molecules, causing the volume expansion of nC8 and its viscosity reduction; (iii) CO2 significantly increases the most probable and average velocities of nC8 molecules, thus improving their mobility. Our results enhance the comprehension of how CO2 facilitates oil flow in water-bearing shale reservoirs and the exploitation of unconventional oil resources.

Dual-Function Nanoscale Coordination Polymer Nanoparticles for Targeted Diagnosis and Therapeutic Delivery in Atherosclerosis.

Atherosclerosis is the primary cause of cardiovascular events such as heart attacks and strokes. However, current medical practice lacks non-invasive, reliable approaches for both imaging atherosclerotic plaques and delivering therapeutic agents directly therein. Here, a biocompatible and biodegradable pH-responsive nanoscale coordination polymers (NCPs) based theranostic system is reported for managing atherosclerosis. NCPs are synthesized with a pH-responsive benzoic-imine (BI) linker and Gd3+. Simvastatin (ST), a statin not used for lowering blood cholesterol but known for its anti-inflammatory and antioxidant effects in mice, is chosen as the model drug. By incorporating ST into the hydrophobic domain of a lipid bilayer shell on NCPs surfaces, ST/NCP-PEG nanoparticles are created that are designed for dual purposes: they diagnose and treat atherosclerosis. When administered intravenously, they target atherosclerotic plaques, breaking down in the mild acidic microenvironment of the plaque to release ST, which reduces inflammation and oxidative stress, and Gd-complexes for MR imaging of the plaques. ST/NCP-PEG nanoparticles show efficacy in slowing the progression of atherosclerosis in live models and allow for simultaneous in vivo monitoring without observed toxicity in major organs. This positions ST/NCP-PEG nanoparticles as a promising strategy for the spontaneous diagnosis and treatment of atherosclerosis.

Application of bidirectional telemedicine in home CPAP for children with obstructive sleep apnea syndrome.

BACKGROUND: Traditional telemedicine follow-up proves unsuitable for home continuous positive airway pressure (CPAP) therapy in children with obstructive sleep apnea syndrome (OSAS). Accompanying advancements in mobile internet, this study explores the feasibility and effectiveness of a mobile communication and remote monitoring system as a novel bidirectional telemedicine approach to enhance adherence to home CPAP in children with OSAS. METHODS: A prospective cohort utilizing bidirectional telemedicine follow-up from January to December 2022 (TM) was compared with a retrospective cohort receiving conventional phone follow-up from August 2018 to December 2021 (CP). Participants in TM group were subdivided into two groups based on the number of inquiries in the first week: a high-question group and a low-question group. The main endpoints included successful CPAP adaption and adherence at 2 months of follow-up. RESULTS: The TM group exhibited a significantly lower termination rate within 2 months compared to the CP group (1/24 vs. 6/22, p = 0.037). In the first week of home CPAP, the high-question group reported shorter average nightly usage and fewer days with usage of ≥4 h compared to the low-question group (5 h per night vs. 8.5 h per night, 4.5 days vs. 7 days, both p < 0.001). However, the high-question group showed significant improvement in adherence from the second week onward for the remainder of the study period. CONCLUSIONS: Bidirectional telemedicine represents an effective and feasible method to improve adherence to home CPAP therapy in children with OSAS. Considering the costs, researchers recommend applying bidirectional telemedicine for at least 1 week to better enhance long-term adherence.

Clinical Impact of Comprehensive Nursing Intervention Combined with Percutaneous Radiofrequency Thermocoagulation for Treating Primary Trigeminal Neuralgia in the Elderly.

Background: Percutaneous radiofrequency thermocoagulation is the foremost minimally invasive approach for treating primary trigeminal neuralgia. However, postoperative complications may arise, necessitating tailored clinical care to enhance patient compliance and mitigate surgical risks. Objective: This study aimed to explore the impact of comprehensive nursing intervention combined with percutaneous radiofrequency thermocoagulation on the management of primary trigeminal neuralgia in elderly patients. Design: A retrospective analysis was conducted. Setting: The study was conducted at the Department of Pain Management, Xuanwu Hospital of Capital Medical University. Participants: A total of 126 elderly patients diagnosed with primary trigeminal neuralgia underwent percutaneous radiofrequency thermocoagulation at our hospital between June 2019 and August 2022. They were enrolled as an observation cohort and randomly assigned to either the control group or the intervention group, with 63 patients in each. Intervention: The control group received standard nursing care, while the intervention group received comprehensive nursing interventions. Primary Outcome Measures: The study assessed (1) negative emotional changes, (2) postoperative status, (3) complications, and (4) quality of life. Results: After the nursing care, the intervention group exhibited significantly lower anxiety and depression scores compared to the control group (P < .05). Additionally, the intervention group had reduced length of hospital stay and pain scores, along with higher nursing satisfaction scores, relative to the control group (P < .05). There was a significant difference in the total complication rate between the two groups (P < .05), with the intervention group experiencing fewer complications. Moreover, the quality of life scores were significantly higher in the intervention group (P < .05). Conclusions: Comprehensive nursing intervention alongside percutaneous radiofrequency thermocoagulation in elderly patients with primary trigeminal neuralgia can decrease complication rates and enhance treatment confidence. These findings support the clinical adoption and dissemination of such interventions.

A Retrospective Comparison of Low-Temperature Plasma Ablation and Radiofrequency Thermocoagulation of the Thoracic Nerve Root for Refractory Postherpetic Neuralgia.

BACKGROUND: Radiofrequency thermocoagulation (RFT) of the thoracic nerve root is commonly employed in treating medication-refractory thoracic post-herpetic neuralgia (PHN). However, RFT procedures' suboptimal pain relief and high occurrence of postoperative skin numbness present persistent challenges. Previous single-cohort research indicated that the low-temperature plasma coblation technique may potentially improve pain relief and reduce the incidence of skin numbness. Nevertheless, conclusive evidence favoring coblation over RFT is lacking. OBJECTIVES: To compare the clinical outcomes associated with coblation to those associated with RFT in the treatment of refractory PHN. STUDY DESIGN: Retrospective matched-cohort study. SETTING: Affiliated Hospital of Capital Medical University. METHODS: Sixty-eight PHN patients underwent coblation procedures between 2019 and 2020, and 312 patients underwent RFT between 2015 and 2020 in our department. A matched-cohort analysis was conducted based on the criteria of age, gender, weight, pain intensity, pain duration, side of pain, and affected thoracic dermatome. Pain relief was assessed using the numeric rating scale (NRS), the Medication Quantification Scale (MQS) Version III and the Neuropathic Pain Symptom Inventory (NPSI), which were employed to indicate pain intensity, medication burden, and comprehensive pain remission at 6, 12, and 24 months. Numbness degree scale scores and complications were recorded to assess safety. RESULTS: We successfully matched a cohort of 59 patients who underwent coblation and an equivalent number of patients who underwent RFT as a PHN treatment. At the follow-up time points, both groups' NRS, MQS, and NPSI scores exhibited significant decreases from the pre-operation scores (P < 0.05). The coblation group's NRS scores were significantly lower than the RFT group's at the sixth and the twenty-fourth months (P < 0.05). At 24 months, the MQS values in the coblation group were significantly lower than those in the RFT group (P < 0.05). Furthermore, the coblation group's total intensity scores on the NPSI were significantly lower than the RFT group's at the 12- and 24-month follow-ups (P < 0.05). At 6 months, the coblation group's temporary intensity scores on the NPSI were significantly lower than the RFT group's (P < 0.05). Notably, the occurrence of moderate or severe numbness in the coblation group was significantly lower than in the RFT group at 6 and 12 months (P < 0.05). No serious adverse effects were reported during the follow-up. LIMITATIONS: This analysis was a single-center retrospective study with a small sample size. CONCLUSION: In this matched cohort analysis, coblation achieved longer-term pain relief with a more minimal incidence rate of skin numbness than did RFT. Further randomized controlled trials should be conducted to solidify coblation's clinical superiority to RFT as a PHN treatment.

Preparation of Asymmetric Al2O3-SiO2 Janus Nanoparticles in Aqueous Phase and Its Interfacial Property.

In this study, asymmetric Al2O3-SiO2 Janus nanoparticles with a dumbbell-like structure were synthesized by a facile chemical process in the aqueous phase. Prior to synthesis, Al2O3 nanoparticles in hydrosol were amino-modified using 3-aminopropyl triethoxysilane (KH550) and then carboxyl acid-functionalized using a ring-opening reaction of the amine functions with succinic anhydride, imparting unique anionic properties to the Al2O3 end. SiO2 nanoparticles were rendered hydrophobic through modification with hexamethyldisilazane (HMDS) and further functionalized with 3-chloropropyl triethoxysilane (KH230). The two nanoparticle hydrosols were then mixed, and the asymmetric Al2O3-SiO2 Janus nanoparticles were synthesized via the reaction between the -NH2 and -CH2Cl groups. The prepared Janus nanoparticles were primarily characterized by dynamic light scattering (DLS), Zeta potential (ZP), and transmission electron microscopy (TEM). The results indicated that about 90% of the modified Al2O3 and SiO2 nanoparticles were covalently coupled in a one-to-one manner to form the dominant dumbbell-like structure. These Janus nanoparticles exhibit amphiphilic properties, making them highly promising surfactants for emulsifying oil-water mixtures.

Herbicide leakage into seawater impacts primary productivity and zooplankton globally.

Predicting the magnitude of herbicide impacts on marine primary productivity remains challenging because the extent of worldwide herbicide pollution in coastal waters and the concentration-response relationships of phytoplankton communities to multiple herbicides are unclear. By analyzing the spatiotemporal distribution of herbicides at 661 bay and gulf stations worldwide from 1990 to 2022, we determined median, third quartile and maximum concentrations of 12 triazine herbicides of 0.18 nmol L-1, 1.27 nmol L-1 and 29.50 nmol L-1 (95%Confidence Interval: CI 1.06, 1.47), respectively. Under current herbicide stress, phytoplankton primary productivity was inhibited by more than 5% at 25% of the sites and by more than 10% at 10% of the sites (95%CI 3.67, 4.34), due to the inhibition of highly abundant sensitive species, community structure/particle size succession (from Bacillariophyta to Dinophyceae and from nano-phytoplankton to micro-phytoplankton), and resulting growth rate reduction. Concurrently, due to food chain cascade effects, the dominant micro-zooplankton population shifted from larger copepod larvae to smaller unicellular ciliates, which might prolong the transmission process in marine food chain and reduce the primary productivity transmission efficiency. As herbicide application rates on farmlands worldwide are correlated with residues in their adjacent seas, a continued future increase in herbicide input may seriously affect the stability of coastal waters.

Occurrence, ecological risk, and advanced removal methods of herbicides in waters: a timely review.

Coastal pollution caused by the importation of agricultural herbicides is one of the main environmental problems that directly affect the coastal primary productivity and even the safety of human seafood. It is urgent to evaluate the ecological risk objectively and explore feasible removal strategies. However, existing studies focus on the runoff distribution and risk assessment of specific herbicides in specific areas, and compared with soil environment, there are few studies on remediation methods for water environment. Therefore, we systematically reviewed the current situation of herbicide pollution in global coastal waters and the dose-response relationships of various herbicides on phytoplankton and higher trophic organisms from the perspective of ecological risks. In addition, we believe that compared with the traditional single physical and chemical remediation methods, biological remediation and its combined technology are the most promising methods for herbicide pollution remediation currently. Therefore, we focus on the application prospects, challenges, and management strategies of new bioremediation systems related to biology, such as constructed wetlands, membrane bioreactor processes, and microbial co-metabolism, in order to provide more advanced methods for reducing herbicide pollution in the water environment.

[Two children with late-onset congenital central hypoventilation syndrome].

Two children with late-onset congenital central hypoventilation syndrome were reported, one of whom was male and had no abnormal manifestations after birth, respiratory failure occurs at the age of 1 year and 6 months. After being hospitalized, he was treated with oxygen inhalation and non-invasive ventilation, but carbon dioxide retention could not be corrected. After one month of tracheal intubation, he was failure to wean from ventilator, so tracheostomy was performed. He needs a ventilator to help breath while sleeping, and can breath autonomously during the day without ventilator. The other case was a female, with no abnormalities after birth. At the age of 11 months, she developed respiratory failure. During sleep, the child needs non-invasive assisted ventilation through a nasal mask, and during the day, she breathed autonomously.Two patients were followed up forever 2 years and their growth and development were normal.

Performance and exploration of ChatGPT in medical examination, records and education in Chinese: Pave the way for medical AI.

BACKGROUND: Although chat generative pre-trained transformer (ChatGPT) has made several successful attempts in the medical field, most notably in answering medical questions in English, no studies have evaluated ChatGPT's performance in a Chinese context for a medical task. OBJECTIVE: The aim of this study was to evaluate ChatGPT's ability to understand medical knowledge in Chinese, as well as its potential to serve as an electronic health infrastructure for medical development, by evaluating its performance in medical examinations, records, and education. METHOD: The Chinese (CNMLE) and English (ENMLE) datasets of the China National Medical Licensing Examination and the Chinese dataset (NEEPM) of the China National Entrance Examination for Postgraduate Clinical Medicine Comprehensive Ability were used to evaluate the performance of ChatGPT (GPT-3.5 and GPT-4). We assessed answer accuracy, verbal fluency, and the classification of incorrect responses owing to hallucinations on multiple occasions. In addition, we tested ChatGPT's performance on discharge summaries and group learning in a Chinese context on a small scale. RESULTS: The accuracy of GPT-3.5 in CNMLE, ENMLE, and NEEPM was 56% (56/100), 76% (76/100), and 62% (62/100), respectively, compared to that of GPT-4, which was of 84% (84/100), 86% (86/100), and 82% (82/100). The verbal fluency of all the ChatGPT responses exceeded 95%. Among the GPT-3.5 incorrect responses, the proportions of open-domain hallucinations were 66 % (29/44), 54 % (14/24), and 63 % (24/38), whereas close-domain hallucinations accounted for 34 % (15/44), 46 % (14/24), and 37 % (14/38), respectively. By contrast, GPT-4 open-domain hallucinations accounted for 56% (9/16), 43% (6/14), and 83% (15/18), while close-domain hallucinations accounted for 44% (7/16), 57% (8/14), and 17% (3/18), respectively. In the discharge summary, ChatGPT demonstrated logical coherence, however GPT-3.5 could not fulfill the quality requirements, while GPT-4 met the qualification of 60% (6/10). In group learning, the verbal fluency and interaction satisfaction with ChatGPT were 100% (10/10). CONCLUSION: ChatGPT based on GPT-4 is at par with Chinese medical practitioners who passed the CNMLE and at the standard required for admission to clinical medical graduate programs in China. The GPT-4 shows promising potential for discharge summarization and group learning. Additionally, it shows high verbal fluency, resulting in a positive human-computer interaction experience. GPT-4 significantly improves multiple capabilities and reduces hallucinations compared to the previous GPT-3.5 model, with a particular leap forward in the Chinese comprehension capability of medical tasks. Artificial intelligence (AI) systems face the challenges of hallucinations, legal risks, and ethical issues. However, we discovered ChatGPT's potential to promote medical development as an electronic health infrastructure, paving the way for Medical AI to become necessary.

Ultrasound-guided transforaminal epidural injection with fluoroscopy confirmation for the treatment of unilateral lumbar radiculopathy: A randomized controlled non-inferiority study.

BACKGROUND: Ultrasound (US)-guided injections for chronic pain has multiple advantages over traditional radiologic method. The study was performed to exam the clinical outcomes of lumbar transforaminal epidural injection (LTFEI) between US and fluoroscopy (FL) guidance for lumbar radiculopathy (LRP). METHODS: A total of 164 patients with LRP were randomly assigned into US and FL group to receive LTFEI in a 1:1 ratio. Pain relief and functional disability were assessed by numeric rating scale (NRS) and Modified Oswestry Disability Questionnaire (MODQ) scores before treatment, 1 month and 3 months post-intervention. Contrast spread pattern, fluoroscopic image number and complications were also recorded. The primary outcome was accurate rate of contrast dispersing into lumbar epidural space, and non-inferiority margin was predefined at -15 %. RESULTS: The accuracy of LTFEI was 90.2 % and 91.5 % in US and FL group, and the lower limit of the 95 %CI of mean difference between two modalities (-4.9 % (95 %CI: -12.8 %, 3.1 %)) was above the non-inferiority margin. Procedure time in US group (531.90 ± 67.12 s) was shorter than FL group (904.20 ± 120.20 s) (p < 0.05), while radiation dosage in the US group was lower than in the FL group (3047.20 ± 569.53 vs. 8807.50 ± 1039.10 µGy m2, p < 0.001). Both groups didn't differ in pain reduction (F = 1.050, p = 0.306) and functional improvement (F = 0.103, p = 0.749) during follow-up period. No severe complications occurred in both groups. CONCLUSIONS: US-guided LTFEI confirmed by FL was not inferior to conventional FL method in terms of accurate rate of lumbar epidural contrast dispersion. Effective pain relief and functional ability improvement were comparable between two modalities, and US technique had advantages of less radiation exposure and possible facilitation of avoiding critical vessels around intervertebral foramen.

A Procedure for Mouse Dorsal Root Ganglion Cryosectioning.

High-quality mouse dorsal root ganglion (DRG) cryostat sections are crucial for proper immunochemistry staining and RNAscope studies in the research of inflammatory and neuropathic pain, itch, as well as other peripheral neurological conditions. However, it remains a challenge to consistently obtain high-quality, intact, and flat cryostat sections onto glass slides because of the tiny sample size of the DRG tissue. So far, there is no article describing an optimal protocol for DRG cryosectioning. This protocol presents a step-by-step method to resolve the frequently encountered difficulties associated with DRG cryosectioning. The presented article explains how to remove the surrounding liquid from the DRG tissue samples, place the DRG sections on the slide facing the same orientation, and flatten the sections on the glass slide without curving up. Although this protocol has been developed for cryosectioning the DRG samples, it can be applied for the cryosectioning of many other tissues with a small sample size.

Percutaneous balloon compression of trigeminal ganglion under conscious sedation local anesthesia for the treatment of primary trigeminal neuralgia-A prospective cohort study.

Introduction: Trigeminal neuralgia is a debilitating condition that can significantly impair the quality of life of affected individuals. Percutaneous balloon compression (PBC) has been established as an effective treatment for this condition. However, the use of general anesthesia during the procedure poses challenges to achieving the desired degree of nerve damage without causing excessive numbness. In this study, we aimed to evaluate the feasibility and efficacy of performing PBC under conscious sedation of local anesthesia. Methods: We improved the surgical procedure for PBC by administering intraganglionic lidocaine 0.2% with fine needle aspiration to achieve conscious sedation. This allowed the operator to determine the degree of nerve damage in real time through the tactile test. We conducted a clinical observation of 87 patients who underwent PBC under conscious sedation of local anesthesia. We evaluated the intraoperative blood pressure and heart rate changes, postoperative facial pain relief, and occurrence of complications such as severe facial numbness, irreversible keratitis, vision loss, and masticatory muscle weakness. Results: All 87 patients achieved immediate relief of facial pain after undergoing PBC under conscious sedation of local anesthesia. The intraoperative blood pressure and heart rate changes were <20% of the baseline value. No patient experienced severe facial numbness or developed irreversible keratitis, vision loss, or masticatory muscle weakness. Discussion: Our findings suggest that PBC under wide-awake local anesthesia is a safe and effective treatment for trigeminal neuralgia. The use of conscious sedation of local anesthesia during the procedure allows the operator to achieve the desired degree of nerve damage without causing excessive numbness. This can lead to long-term pain relief and improved quality of life for patients with trigeminal neuralgia.

Incidence of myopericarditis after mRNA COVID-19 vaccination: A meta-analysis with focus on adolescents aged 12-17 years.

BACKGROUND: The incidence of myopericarditis after mRNA COVID-19 vaccination among adolescents aged 12-17 years remains unknown. Therefore, we conducted a study to pool the incidence of myopericarditis following COVID-19 vaccination in this age group. METHODS: We did a meta-analysis by searching 4 electronic databases until February 6, 2023. The following main keywords were used: "COVID-19", "vaccines", "myocarditis", "pericarditis", and "myopericarditis". Observational studies reporting on adolescents aged 12-17 years who had myopericarditis in temporal relation to receiving mRNA COVID-19 vaccines were included. The pooled incidence of myopericarditis and 95 % confidence interval (CI) were calculated using a single-group meta-analysis. RESULTS: Fifteen studies were included. The pooled incidences of myopericarditis after mRNA COVID-19 vaccination among adolescents aged 12-17 years were 43.5 (95 % CI, 30.8-61.6) cases per million vaccine doses for both BNT162b2 and mRNA-1273 (39 628 242 doses; 14 studies), and 41.8 (29.4-59.4) cases for BNT162b2 alone (38 756 553 doses; 13 studies). Myopericarditis was more common among males (66.0 [40.5-107.7] cases) than females (10.1 [6.0-17.0] cases) and among those receiving the second dose (60.4 [37.6-96.9] cases) than those receiving the first dose (16.6 [8.7-31.9] cases). The incidences of myopericarditis did not differ significantly when grouped by age, type of myopericarditis, country, and World Health Organization region. None of the incidences of myopericarditis pooled in the current study were higher than those after smallpox vaccinations and non-COVID-19 vaccinations, and all of them were significantly lower than those in adolescents aged 12-17 years after COVID-19 infection. CONCLUSIONS: The incidences of myopericarditis after mRNA COVID-19 vaccination among adolescents aged 12-17 years were very rare; they were not higher than other important reference incidences. These findings provide an important context for health policy makers and parents with vaccination hesitancy to weight the risks and benefits of mRNA COVID-19 vaccination among adolescents aged 12-17 years.

An updated patent review of IDO1 inhibitors for cancer (2018-2022).

INTRODUCTION: Indoleamine 2,3-dioxygenase 1 (IDO1) is highly related to the immune evasion of a wide range of malignancies due to its role in the immune suppression caused by the depletion of tryptophan (Trp) and the accumulation of kynurenine (Kyn). The combination of IDO1 inhibitors with other treatments represents a promising strategy in immunotherapy, although considerable challenges lie ahead. AREAS COVERED: This review focuses on patent publications searched from Espacenet and Google Scholar, and related to IDO1 inhibitors with potential anti-cancer utilization during the period 2018-2022. EXPERT OPINION: Despite the clinical trial failure of the first-in-class IDO1 inhibitor epacadostat in combination with pembrolizumab, numerous studies have been carried on to pursue more efficient IDO1-based immune-modulating therapeutic solutions. A large number of IDO1 inhibitors with new structures and design concepts have been produced with the impetus of crystallographic studies, and have shown great research potential. The elaboration on the combination of IDO1 inhibitors with other targeting agents, the more precise selection of patients, the identification of more reliable biomarkers for evaluating the IDO1 treatment, and the investigation of possible toxicity, are critical factors to promote IDO1-based immunotherapies from bench to bedside.

Noninvasive ventilation via bilevel positive airway pressure improved sleep in a child with congenital central hypoventilation syndrome: A case report.

We report the polysomnography findings of a 2-year-old girl who was previously diagnosed with CCHS and treated with bilevel positive airway pressure (BiPAP) and O2 supplementation for a year. The girl had convulsions 2 times in the last 10 days. After we replaced her nasal cannula with a nasal mask and adjusted the parameters of the BiPAP, her sleep and ventilation were improved. The polysomnographies measured under spontaneous breathing without oxygen supplementation showed that her sleep structure, heart rate, and oxygen saturation during sleep were improved 1 month and 1 year after effective BiPAP treatment.

[Preliminary study on efficacy and safety of submucosal plasma ablation of inferior turbinate in children with allergic rhinitis complicated with obstructive sleep apnea syndrome].

Objective:This study aimed to investigate the long-term clinical efficacy and safety of inferior turbinate submucosal plasma ablation combined with or without tonsillar and adenoid surgery in children with allergic rhinitis（AR） combined with obstructive sleep apnea syndrome（OSAS） who were ineffective after conservative systemic treatment. Methods:A total of 43 children with AR complicated with OSAS who met the inclusion criteria among 68 children hospitalized from January 2019 to February 2022 were retrospectively analyzed. The data were collected, including the clinical characteristics, surgical methods perioperative management and prevention and treatment of complications. Moreover, one year follow-up was performed to compare the VAS scores of children before and after surgery, and to evaluate their mid-term and long-term outcomes. Results:The average operation time was 36 minutes, meanwhile, the intraoperative blood was limited. The symptoms of nasal congestion, runny nose, sleep snoring, and mouth breathing were significantly improved after operation, and the results were satisfactory after one-year follow-up without complications such as bleeding, hematoma, intraoperative adhesion, and nasal dryness. Conclusion:Submucosal plasma ablation of inferior turbinate with or without tonsillectomy adenoidectomy in children with AR can effectively improve the clinical symptoms of AR combined with OSAS children who are ineffective after conservative treatment. It can improve the symptoms of sleep-disordered breathing such as sleep snoring and mouth breathing, with good mid-and long-term curative effects and fewer complications, which is an effective and safe treatment for children with AR combined with OSAS.

Prevalence of autism spectrum disorder diagnosis by birth weight, gestational age, and size for gestational age: a systematic review, meta-analysis, and meta-regression.

We aimed to comprehensively pool the prevalence of autism spectrum disorder (ASD) diagnosis by birth weight, gestational age, and size for gestational age. PubMed, EMBASE, Web of Science, Ovid PsycINFO, and Cochrane Library were searched up to December 22, 2021. We pooled data using the random-effects model and quantified heterogeneity using the I2 statistic. Of 66 643 records initially identified, 75 studies were included in the meta-analysis. The pooled prevalence estimates of ASD diagnosis are as follows: very-low-birth weight, 3.1% (912 ASD/66,445 individuals); low-birth weight, 2.3% (5672 ASD/593,927 individuals); normal-birth weight, 0.5% (17,361 ASD/2,378,933 individuals); high-birth weight, 0.6% (4505 ASD/430,699 individuals); very preterm, 2.8% (2113 ASD/128,513 individuals); preterm, 2.1% (19 672 ASD/1 725 244 individuals); term, 0.6% (113,261 ASD/15,297,259 individuals); postterm, 0.6% (9419 ASD/1,138,215 individuals); small-for-gestational-age, 1.9% (6314 ASD/796,550 individuals); appropriate-for-gestational-age, 0.7% (21,026 ASD/5,936,704 individuals); and large-for-gestational-age, 0.6% (2607 ASD/635,666 individuals). Compared with the reference prevalence (those in normal-birth weight, term, and appropriate-for-gestational-age individuals), the prevalence estimates of ASD diagnosis in very-low-birth weight, low-birth weight, very preterm, preterm, and small-for-gestational-age individuals increased significantly, while those in high-birth weight, postterm, and large-for-gestational-age individuals did not change significantly. There were geographical differences in the prevalence estimates. This meta-analysis provided reliable estimates of the prevalence of ASD diagnosis by birth weight, gestational age, and size for gestational age, and suggested that low-birth weight (especially very-low-birth weight), preterm (especially very preterm), and small-for-gestational-age births, rather than high-birth weight, postterm, and large-for-gestational-age births, were associated with increased risk of ASD diagnosis. However, in view of marked between-study heterogeneity in most conditions, unknown effects of certain important confounders associated with ASD due to limited information in original articles, and included studies from a relatively small number of countries, the findings of this study should be interpreted with caution.

Long-term outcomes and predictors of percutaneous radiofrequency thermocoagulation of Gasserian ganglion for maxillary trigeminal neuralgia: a retrospective analysis of 1070 patients with minimum 2-year follow-up.

OBJECTIVE: To estimate long-term efficacy and safety for maxillary trigeminal neuralgia (TN) using radiofrequency thermocoagulation (RFT) targeted on Gasserian ganglion, and to identify the factors which may influence outcomes after procedure. METHODS: From 2006 to 2019, 1070 patients underwent RFT for the treatment of medically refractory maxillary TN was included. All patients were followed up for at least 2 years. Outcomes and complications were recorded and analysed. Logistic regression analysis was employed to identify risk factors of long-term pain recurrence. Prognostic value was calculated from receiver-operating characteristic curve (ROC). RESULTS: Longitudinal analysis was taken place for 97 non-responders (9.1%) with ineffective pain relief, 253 responders (23.6%) with pain recurrence and 720 responders (67.3%) without pain recurrence. The median pain-free survival (PFS) was 112.0 months (95% CI: 107.5, 116.5). The pain-free rates were 89.9% (95% CI: 88.0-91.8%) at 1 year, 83.8% (95% CI: 81.5-86.1%) at 2 years, 75.4% (95% CI: 72.7-78.1%) at 5 years and 70.2% (95% CI: 67.4-73.0%) at 10 years. Atypical facial pain (HR = 5.373, 95% CI: 2.623-11.004, p < .001), previous facial numbness (HR = 5.224, 95% CI: 3.107-8.784, p < .001) and poor initial response to medication (HR = 3.185, 95% CI: 2.087-4.860, p < .001) were independently associated with long-term pain recurrence. Patients with prognostic index (PI) > 0.25 were identified as high-risk for recurrent TN (HR = 5.575, 95% CI: 3.991-7.788, p < .001). New and worsen facial hypoesthesia was recorded in 77.9% of patients corresponding with BNI score II-IV, and 18.7% reported improved sensation. Severe complication incidence including troublesome dysesthaesia, keratitis and masseter weakness was higher in 80 °C group. CONCLUSIONS: Favourable outcomes were achieved in terms of long-term pain relief and complications rate after RFT for maxillary TN. Patients with typical facial pain, normal facial sensation, and good initial response to medications may have favourable long-term outcomes.Key messagesThis is a retrospective analysis of radiofrequency thermocoagulation (RFT) targeted on Gasserian ganglion for the treatment of maxillary trigeminal neuralgia (TN) during long-term follow-up. Recurrence-free survival among a large sample was assessed and risk factors associated with long-term pain recurrence was identified. It has been verified that inadvertent damage of ophthalmic and mandibular division causes ophthalmic and masticatory complications. Therefore, a more precise needle tip position and thermocoagulation using a relatively low temperature was recommended.
