Effect of recorded mother's voice on emergence delirium in pediatric patients: a systematic review with meta-analysis

Abstract Objective: Emergence delirium is a common complication in children. Recorded mother's voice, as a non-pharmacological measure, is increasingly used to prevent the emergence of delirium in pediatric patients, but sufficient evidence is still needed to prove its efficacy. Methods: Embase, PubMed, Cochrane Library, Web of Science, CINAHL, and Sinomed databases were searched for randomized controlled trials exploring the efficacy of recorded mother's voice in preventing the emergence of delirium in pediatric patients undergoing general anesthesia. The original data were pooled for the meta-analysis with Review Manager 5.4.1. This study was conducted based on the Cochrane Review Methods. Results: Eight studies with 724 children were included in the analysis. Recorded mother's voice reduced the incidence of emergence delirium when compared with either no voice (RR: 0.45; [95 % CI, 0.34 - 0.61]; p < 0.01; I2 = 7 %) or stranger's voice (RR: 0.51; [95 % CI, 0.28 - 0.91]; p = 0.02; I2 = 38 %) without increasing other untoward reactions. In addition, it shortened the post-anesthesia care unit stay time when compared with no voice (MD = -5.64; [95 % CI, -8.43 to -2.58]; p < 0.01, I2 = 0 %), but not stranger's voice (MD = -1.23; [95 % CI, -3.08 to 0.63]; p = 0.19, I2 = 0 %). It also shortened the extubation time and reduced the incidence of postoperative rescue analgesia. Conclusion: The current analysis indicated that recorded mother's voices could reduce the incidence of emergency delirium, shorten post-anesthesia care unit stay time and extubation time, and decrease the incidence of postoperative rescue analgesia in children.

Effect of pump infusion of esmketamine on emergence agitation induced by etomidate target-con-trolled infusion / 临床麻醉学杂志

Objective To investigate the effect of constant speed pump infusion of esmketamine on emergence agitation(EA)after target-controlled infusion of etomidate.Methods A total of 120 patients scheduled for middle ear tympanoplasty under target-controlled infusion of etomidate,61 males and 59 fe-males,aged 18-64 years,BMI 18-30 kg/m2,ASA physical status Ⅰ or Ⅱ,were randomly divided into two groups:the esmketamine group(group E)and the control group(group C),60 patients in each group.From the beginning of anesthesia induction to 30 minutes before the end of operation,esmketamine 0.2 ml·kg-1·h-1 in group E and saline injection 0.2 ml·kg-1·h-1 in group C were injected,respectively.The operation time,anesthesia time,awakening time,extubation time,and the duration in PACU were re-corded.The incidence of EA,the VAS pain scores when leaving PACU and 1 day after operation,the inci-dence and VAS score of nausea and vomiting 1 day after operation were evaluated.The anxiety and depres-sion scores of the two groups were evaluated before operation,1 day and 2 days after operation.Results The incidence of EA,VAS pain score when leaving PACU and 1 day after operation in group E were signifi-cantly lower than those in group C(P＜0.05).There was no significant difference in operation time,anes-thesia time,awakening time,extubation time,the duration in PACU,incidence and VAS score of nausea and vomiting 1 day after operation,and the indexes of anxiety and depression at different time points be-tween the two groups.Conclusion Esmketamine pump infusion combined with etomidate target-controlled infusion can reduce emergence agitation and promote postoperative recovery.

Effects of the timing of satisfactory sedation with preoperative oral midazolam on anesthesia induction and recovery in children undergoing adenotonsillectomy / 中国临床药理学与治疗学

AIM: To investigate the effect of the timing of satisfactory sedation with preoperative oral midazolam on anesthesia induction and recovery in children undergoing adenotonsillectomy. METHODS: A total of 147 children undergoing elective adenotonsillectomy, with ASA physical status orⅡ, aged 2-7 years were selected from November 2022 to June 2023 in the Second Affiliated Hospital of Wenzhou Medical University. The children were orally administered 0.5 mg/kg midazolam in preoperative waiting area and were divided into 10-20 min (rapid onset, M1 group) and 21-30 min (slow onset, M2 group) based on the satisfactory sedation time, or equal volume of sugar pear drink orally (blank control group, C group). Children in all three groups received a general anesthesia method of propofol+fentanyl combined with sevoflurane induction and sevoflurane maintenance. The primary outcome measures were the induction compliance checklist (ICC) score and the pediatric anesthesia emergence delirium (PAED) score in the post-anesthesia care unit (PACU) to assess the occurrence of emergence agitation (EA), and the secondary outcome measures included the parental separation anxiety scale (PSAS), sedation Ramsay score, surgery duration, recovery time, PACU stay time, discharge time, the incidence of perioperative respiratory adverse events (PRAE) and other adverse events in the ward. RESULTS: 147 children were included in the result analysis, with 49 cases in each group. The proportion of perfect induction (ICC=0) were significantly higher in two M groups than that in group C (95.9% vs. 91.8% vs. 61.2%, P=0.001). The maximum and average PAED score in PACU in group M1 showed a significantly higher (6.4±5.0 vs. 4.4 ± 4.1, P=0.029; 5.2 ± 4.5 vs. 3.4 ± 3.6, P=0.030), and the incidence of EA was significantly higher than those in group C (10.2% vs. 30.6%, P=0.022), and increased compared to the group M2 (OR= 0.581, 95%CI 0.231-1.463, P=0.354). There was no statistically significant difference in the maximum and average PAED scores, incidence of EA between group M2 and group C (P>0.05). The Ramsay score and PSAS score in two M groups were higher, PACU stay time and recovery time was longer than those in group C (P0.05). CONCLUSION: Preoperative oral midazolam can improve the ICC and PSAS scores of children during induction, but it also leads to prolonged recovery time and PACU retention time. The rapid onset of midazolam did not result in better induction and recovery quality, but instead increased the incidence of EA and postoperative pain score.

The effect of ultrasound-guided myofascial tube combined with knee joint posterior capsule space block on postoperative delirium in elderly patients undergoing total knee arthroplasty / 中国医师杂志

Objective:To evaluate the effect of ultrasound-guided adductor canal combined with knee joint posterior capsule space block on the recovery period delirium in elderly patients undergoing total knee arthroplasty (TKA).Methods:A total of 68 elderly patients who underwent unilateral TKA at the Nanjing First Hospital from December 2021 to December 2022 were selected. They were randomly divided into a control group ( n=34) and an observation group ( n=34) using a random number table method. Both groups received general anesthesia, and the observation group received ultrasound-guided myofascial tube combined with knee joint posterior capsule space block before the surgery began. The incidence of delirium within 24 hours after surgery was mainly observed in two groups of patients. The surgical time, recovery time, intraoperative blood loss, infusion volume, total use of propofol and remifentanil were recorded; The resting and motor Visual Analogue Scale (VAS) scores of the patient were recorded at 4, 8, and 24 hours postoperatively. The patient′s serum tumor necrosis factor-α (TNF-α) and melatonin levels were measured on the day before surgery, the evening after surgery, and the first day after surgery. The subjective sleep quality score was recorded on the first day after surgery; The total dosage of sufentanil for patient-controlled intravenous analgesia (PCIA) within 24 hours after surgery, the effective number of compressions (P1) and actual number of compressions (P2) of PCIA, and the number of cases of additional oxycodone analgesia were recorded; The occurrence of respiratory depression, excessive sedation, nausea, and vomiting within 24 hours after surgery was recorded; The occurrence of complications of nerve block in the observation group was recorded. Results:The incidence of delirium during the recovery period in the observation group was lower than that in the control group ( P<0.05). The dosage of propofol and remifentanil in the observation group was lower than that in the control group (all P<0.05), and the awakening time was shorter than that in the control group ( P<0.05). The VAS scores at rest and exercise at 4, 8, and 24 hours after surgery in the observation group were lower than those in the control group (all P<0.05). Compared with the day before surgery, the observation group showed an increase in melatonin levels on the night after surgery ( P<0.05) and an increase in TNF-α levels on the first day after surgery ( P<0.05); The control group had a decrease in melatonin levels on the first day after surgery ( P<0.05), and an increase in TNF-α levels on the night and day after surgery (all P<0.05). The serum melatonin levels in the observation group were higher than those in the control group on the evening and first day after surgery (all P<0.05), and TNF-α levels were lower than those in the control group (all P<0.05). The subjective sleep quality score of the observation group showed that the total dosage of PCIA sufentanil, P1, P2, and the number of cases of additional oxycodone analgesia within 24 hours after surgery were lower than those of the control group (all P<0.05). The incidence of nausea in the control group (13 cases, 38.2%) was higher than that in the observation group (3 cases, 8.8%) ( P<0.05). Conclusions:In elderly patients undergoing unilateral TKA under general anesthesia, preoperative use of ultrasound-guided adductor tube combined with knee joint posterior capsule space block can effectively reduce the occurrence of postoperative delirium.

Association between intraoperative ketamine and the incidence of emergence delirium in laparoscopic surgeries: an observational study

Abstract Background: Emergence Delirium (ED) is an essential condition in the immediate postoperative period. Systematic review and meta-analysis of randomized controlled trials have concluded that the effect of ketamine on postoperative delirium remains unclear. The present study sought to evaluate if the intraoperative use of ketamine for postoperative analgesia is associated with postoperative ED in laparoscopic surgeries. Methods: A prospective observational study was performed in the PostAnesthetic Care Unit (PACU) to evaluate patients who had undergone laparoscopic surgery under a rigid intraoperative anesthesia protocol from July 2018 to January 2019. Patients submitted to laparoscopic surgery for cholecystectomy, oophorectomy, or salpingectomy with a score ≥1 on the Richmond Assessment Sedation Scale (RASS) or ≥2 on the Nursing Delirium Screening Scale (Nu-DESC) were considered to have ED. t-test, Chi-Square test or Fisher's exact tests were used for comparison. Results: One hundred and fifteen patients were studied after laparoscopic surgery. Seventeen patients (14.8%) developed ED, and the incidence of ED in patients who received ketamine was not different from that of other patients (18.3% vs. 10.6%, p = 0.262). Patients with ED had more postoperative pain and morphine requirement at the PACU (p = 0.005 and p = 0.025, respectively). Type of surgery (general surgery, OR = 6.4, 95% CI 1.2‒35.2) and postoperative pain (OR = 3.7, 95% CI 1.2‒11.4) were risk factors for ED. Conclusion: In this study, no association was found between ED and intraoperative administration of ketamine in laparoscopic surgeries. Type of surgery and postoperative pain were risk factors for ED.

Predisposing and precipitating factors for the development of postoperative delirium in critically ill patients in a university intensive care unit / Fatores predisponentes e precipitantes para o desenvolvimento de delirium pós-operatório em pacientes críticos de uma unidade intensiva universitária / Factores predisponentes y precipitantes para el desarrollo del delirium postoperatorio en pacientes críticos de una unidad intensiva universitaria

Abstract Objective: to detect the incidence of postoperative delirium in critically ill patients admitted to a surgical intensive care unit and to evaluate the predisposing and precipitating factors associated with postoperative delirium in critically ill patients admitted to a surgical intensive care unit. Method: this is a prospective cohort study of 157 critically ill surgical patients. Fisher's exact test and Chi-square test were used for the association between factors and the occurrence of delirium, the Wilcoxon test for numerical variables, and the logistic regression model for the analysis of predisposing and precipitating factors. Results: the incidence of delirium was 28% (n=44). Age was a significant predisposing factor (p=0.001), followed by the length of surgery (p<0.001), blood transfusion (p=0.043), administration of crystalloids (p=0.008), and anti-inflammatory drugs (p=0.037), which were the precipitating factors identified. The best-adjusted models were: age, length of surgery, non-administration of anti-emetics, use of sufentanil, and blood transfusion. Conclusion: delirium is a frequent condition in critically ill adults undergoing surgery and the existence of precipitating and predisposing factors is relevant to the outcome, with the anesthetic-surgical procedure as the catalyst event.

Conclusiones: El dolor se asoció con el delirio de emergencia posanestésico en niños. La prevención y el tratamiento del delirio de emergencia deben centrarse en el control del dolor posoperatorio y en la vigilancia cuidadosa de los pacientes después de la cirugía.

ABSTRACT Objective: Identify associated factors with emergence delirium in children in the Post-Anesthetic Recovery Unit of a Pediatric Health Specialized Institute in Peru. Methods: A cross-sectional study was carried out in children from 2 to 6 years old, physical status classification I and II, in elective procedures under anesthesia. The main variable was the presence of emergence delirium evaluated with the Pediatric Anesthesia Emergence Delirium scale greater than or equal to 10 points. To identify the factors associated with delirium, the Poisson regression model was applied and a p value < 0.05 was considered significant. Results: Of the 150 children, it was found that the incidence of emergence delirium occurred in 10.6%. Of these, 81.4% were under 5 years of age, pain was significantly associated in 37.5% with PR = 3.63, 95%CI [1.20, 10.1] and it was observed that 68, 8% required palliative care. Conclusion: Pain was associated with delirium of postanesthetic emergence in children. Prevention and treatment of emergence delirium should focus on postoperative pain control and careful monitoring of patients after surgery.

Premedication with midazolam in low-risk surgery in children does not reduce postoperative delirium. Prospective cohort study

Introduction: Pediatric postoperative delirium is a frequent complication for which preventive pharmacological measures have been suggested. The use of midazolam as a prophylactic strategy has not yet been thoroughly assessed. Notwithstanding the fact that it is used in pediatric presurgical separation anxiety, its role in delirium is yet to be established. Objective: To quantify the incidence of pediatric postoperative delirium in patients undergoing low risk surgical interventions, exposed to oral midazolam-based premedication and to explore the protective and risk factors associated with the development of delirium. Methods: Prospective, analytical observational study with a cohort design. Children were conveniently selected in accordance with the daily list of surgical procedures in the operating rooms. The inclusion criteria were children between 2 and 10 years old, ASA I-II, undergoing low risk surgeries. Concurrent and longitudinal follow-up was then conducted upon admission to the post-anesthesia care unit (PACU) for the first hour. Results: A total of 518 children were included. The overall incidence of delirium was 14.4 % (95 % CI: 11.4 %-17.5 %). In the subgroup exposed to midazolam, 178 children were analyzed, with an incidence of delirium of 16.2% (95% CI of 10,8 %-21,7). These patients exhibited a higher tendency to delirium with the use of sevoflurane or fentanyl, and/orwhen presenting with severe postoperative pain. Patients exposed to propofol and/or remifentanil showed lower incidences. Conclusions: No reduction in the incidence of emergency pediatric delirium associated with the use of pre-surgical oral midazolam in low risk surgical procedures. Prospective controlled trials and additional research are required to study the effectiveness and safety of this intervention.

Introducción: El delirio pediátrico posoperatorio es una complicación frecuente para la cual se han sugerido medidas farmacológicas de prevención. El uso de midazolam como estrategia profiláctica aún no ha sido suficientemente evaluado. A pesar de que se emplea para la ansiedad de separación pediátrica prequirúrgica, su papel en delirio aún no se ha establecido. Objetivo: Cuantificar la incidencia de delirio pediátrico posoperatorio en pacientes sometidos a cirugías de bajo riesgo quirúrgico, expuestos a premedicación basada en midazolam oral y adicionalmente, explorar los factores protectores y de riesgo asociados a la ocurrencia. Materiales y métodos: Estudio observacional analítico prospectivo con un diseño de cohorte. Se seleccionaron niños por conveniencia de acuerdo con la lista quirúrgica diaria en salas de cirugía. Como criterios de inclusión se tomaron sujetos entre 2 y 10 años de edad, ASA 1-11, sometidos a cirugías de bajo riesgo quirúrgico. Posteriormente se realizó seguimiento concurrente y longitudinal al ingreso a la unidad de recuperación posanestésica (UCPA) durante la primera hora de estancia. Resultados: Se incluyeron 518 niños. La incidencia global de delirio fue del 14,4 % (IC 95 %;11,4 %-17,5 %). En el subgrupo expuesto a midazolam se analizaron 178 niños, quienes presentaron una incidencia de delirio del 16,2 % (IC 95 %;10,8 %-21,7 %). Estos pacientes presentaron una mayor tendencia a delirio con el uso de sevofluorano o fentanilo, y/o cuando presentaron dolor severo posoperatorio. Pacientes con exposición a propofol y/o remifentanilo exhibieron incidencias inferiores. Conclusiones: No se encontró una reducción en la incidencia de delirio pediátrico de emergencia asociada al empleo de midazolam oral prequirúrgico en cirugías de bajo riesgo. Se requieren estudios prospectivos controlados e investigación adicional para el estudio de la efectividad y seguridad de esta intervención.

Single-bolus dexmedetomidine in prevention of emergence delirium in pediatric ophthalmic surgeries: A randomized controlled trial

Purpose: Emergency delirium (ED), a common postoperative neurologic complication, causes behavioral disturbances leading to self?traumas and also has long?term adverse effects in children. Our aim was to investigate the efficacy of a single?bolus dose of dexmedetomidine in reducing the incidence of ED. Additionally, pain relief, number of patients who needed rescue analgesia, hemodynamic parameters, and adverse events were assessed. Methods: One hundred and one patients were randomly allocated into two groups: 50 patients received 15 mL of dexmedetomidine 0.4 ?g/kg (group D) and 51 patients received volume?matched normal saline (group C). Hemodynamic parameters such as heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were monitored regularly throughout the procedure. ED was assessed with Pediatric Anesthesia Emergence Delirium Scale (PAEDS), and pain was measured using the modified Objective Pain Score (MOPS). Results: The incidences of ED and pain were higher in group C than group D (P < 0.0001 and P < 0.0001, respectively). Group D showed significant decrease in MOPS and PAEDS values at 5, 10, 15, and 20 min (P < 0.05), HR at 5 min (P < 0.0243), and SBP at 15 min (P < 0.0127). There was no significant difference in DBP between the two groups at any time point. The mean blood pressure (MBP) at 10 min was significantly less in group D than group C (P < 0.001). Conclusion: Dexmedetomidine 0.4 ?g/kg as a single bolus over 10 min immediately after intubation is effective for the prevention of ED and significantly reduces the need of rescue analgesia without compromising the hemodynamic parameters in children undergoing ophthalmic surgery.

The impact of emergence delirium on hospital length of stay for children who underwent tonsillectomy/adenotonsillectomy: an observational retrospective study

Abstract Background Emergence Delirium (ED) is a combination of disturbance of perception and psychomotor agitation that is common in pediatric patients after general anesthesia, especially at preschool age. Since the effect of ED on the length of stay has been studied in adults but infrequently in children, the aim of this study was to investigate the relationship between ED and length of stay in this population. Methods A single center, retrospective, observational study was carried out in children who underwent tonsillectomy or adenotonsillectomy. The Pediatric Anesthesia Emergence Delirium (PAED) scale was used to assess ED. In addition to the time to hospital discharge (time frame 24 hours), drugs used, comorbidities, early postoperative complications, and pain were investigated if potentially associated with the complication. Results Four hundred sixteen children aged from 1.5 to 10 years (183 female, 233 male) were included. ED occurred in 25.5% of patients (n = 106). Patients were divided into the ED group and the No-ED group. The discharge time was similar in both groups. No significant differences were observed in the frequency of postoperative complications. The use of fentanyl or dexmedetomidine did not affect ED occurrence. The frequency of pain was greater in the ED group, both in the recovery room and in the ward (p= 0.01). Conclusions The occurrence of ED in children after tonsillectomy/adenotonsillectomy did not extend the length of stay.

The SARS-CoV-2 variants around us: A literature review

ABSTRACT@#The SARS-CoV-2 outbreak in Wuhan (China) has become a global pandemic. Various variants of SARS-CoV-2 have been detected and the variant number of the virus continues to grow. A particular SARS-CoV-2 variant can be detected in a country that was never infected before by the virus. Furthermore, a specific SARS-CoV-2 variant, which has been detected before in a country, can be detected too in another country. The emergence of SARS-CoV-2 variants is mainly caused by mutations and recombinations. The emergence of a SARS-CoV-2 variant in a country (which was never infected before by the virus), of course, can be explained easily as it is caused by the effect of the viral spread among countries, although there may be another explanation. On the other hand, the emergence of a SARS-CoV-2 variant (which has been previously detected in a country) in another country, always has been explained only as it is caused by the effect of the viral spread between countries. However, maybe it is caused by another factor. A literature review was performed to look for the explanation related to the emergence of a certain SARS-Cov-2 variant (which is already detected before in another country) in a country. Based on the literature review results related to the RNA virus genome and its mutation as well as its recombination, it is easy to explain the cause/agent of the emergence of a SARS-CoV-2 variant (which has been previously detected elsewhere) in another country. In this case, the emergence of a SARS-CoV-2 variant (which has been previously detected elsewhere) in a country may be caused by mutations and/or recombinations in addition to the probability that it may also occur due to the spread of the virus among countries; so the emergence of SARS-CoV-2 variant that has been previously detected elsewhere in other countries does not only occur due to the spread of the virus.

Distribution characteristics of emerging and reemerging Oncomelania hupensis in China from 2015 to 2021 / 中国血吸虫病防治杂志

OBJECTIVE@#To analyze the distribution characteristics of emerging and reemerging Oncomelania hupensis snails after the criteria for transmission control of schistosomiasis were achieved in China, so as to provide insights into assessment of schistosomiasis transmission risk and formulation of snail control strategies during the elimination phase.@*METHODS@#O. hupensis survey data in China from 2015 to 2021 were collected from the National Schistosomiasis Pevention and Control Information Management System, and the distribution characteristics of emerging and reemerging O. hupensis snails were descriptively analyzed.@*RESULTS@#Emerging and reemerging O. hupensis snails were identified in China each year from 2015 to 2021, with relatively larger areas with emerging and reemerging O. hupensis snail habitats in 2016 and 2021, and relatively higher numbers of counties (districts) where emerging and reemerging O. hupensis snails were detected in 2016 and 2021. A total of 4 586.30 hm2 of emerging O. hupensis snail habitats were found in 10 schistosomiasis-endemic provinces of China (except Fujian and Yunnan Provinces) from 2015 to 2021, with 96.80% in Anhui, Hunan and Hubei provinces, where marshland and lake endemic foci were predominant. A total of 21 023.90 hm2 of reemerging O. hupensis snail habitats were found in 12 schistosomiasis-endemic provinces of China from 2015 to 2021, with 97.67% in six provinces of Hubei, Sichuan, Jiangxi, Jiangsu, Yunnan and Anhui, where marshland and lake and hilly endemic regions were predominant. Emerging snail habitats were found in 15.08% of all schistosomiasisendemic counties (districts) in China from 2015 to 2021, and 78.75% of all emerging snail habitats were identified in 11 schistosomiasis-endemic counties (districts), with the largest area of emerging snail habitats found in Lixian County, Hunan Province (645.00 hm2). Reemerging snail habitats were found in 47.67% of all schistosomiasis-endemic counties (districts) in China from 2015 to 2021, and 43.29% of all reemerging snail habitats were identified in 11 schistosomiasis-endemic counties (districts), with the largest area of reemerging snail habitats found in Weishan Li and Hui Autonomous County of Hunan Province (1 579.70 hm2).@*CONCLUSIONS@#Emerging and reemerging O. hupensis snails were identified in China each year from 2015 to 2021, with much larger areas of reemerging snail habitats than emerging snail habitats, and larger numbers of schistosomiasis-endemic provinces and counties (districts) with reemerging snails were found that those of provinces and counties (districts) with emerging snails. Specific snail control interventions are required tailored to the causes of emerging and reemerging snail habitats. Both emergence and reemergence of O. hupensis snails should be paid attention to in marshland and lake endemic areas, and Guangxi Zhuang Autonomous Region, Shanghai Municipality and Zhejiang Province where schistosomiasis had been eliminated, and reemergence of O. hupensis snails should be given a high priority in hilly areas. In addition, monitoring of O. hupensis snails should be reinforced in snail-free areas after flooding.

Effect of multimodal non-drug treatment during induction of general anesthesia on emergence delirium in preschool children / 中华麻醉学杂志

Objective:To evaluate the effect of multimodal non-drug treatment during induction of general anesthesia on emergence delirium (ED) in the preschool children.Methods:A total of 210 pediatric patients of either sex, aged 3-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰor Ⅱ, undergoing elective operation for snoring with expected operation time <2 h, were involved in this study. The patients were divided into 2 groups according to the parity of the numbers randomly generated by the computer: multimodal non-drug treatment group (group N, n=102) and control group (group C, n=108). In group N, multiple modes of non-drug intervention (including parents′ company, carrying favorite toys, watching favorite video programs with portable multimedia devices, etc) were used during anesthesia induction, and the children left their parents and entered the operating room after completion of general anesthesia. The children directly entered the operating room with the medical staff for anesthesia induction (without parents′ company and other intervention measures) in group C. The patients were endotracheally intubated and received combined intravenous-inhalational anesthesia and general anesthesia in both groups. The anxiety was evaluated by modified Yale preoperative anxiety scale (m-YPAS) score at 24 h before operation (T 0) and immediately before induction of general anesthesia (T 1). The Pediatric Anesthesia Emergence Delirium scale score (PAED score, ED was defined as PAED score > 12), FLACC scale score and Ramsay Sedation Scale score were recorded when orientation recovered after admission to postanesthesia care unit (T 2) and at 6, 24 and 72 h after operation. The patients were divided into ED group and non-ED group (NED group) according to the occurrence of ED, and the risk factors of which P values were less than 0.05 would enter the multivariate logistic regression analysis to stratify ED-related risk factors and construct the prediction model. The accuracy of the prediction model was evaluated by the receiver operating characteristic curve. Results:Compared with group C, the m-YPAS at T 1 and PAED score and incidence of ED at T 2 were significantly decreased ( P<0.05), and no significant change was found in FLACC score and Ramsay sedation score at all time points in group N ( P>0.05). Age, m-YPAS score at T 1, multimodal non-drug treatment during anesthesia induction, FLACC score at T 2 and Ramsay sedation score at T 2 were the risk factors for ED ( P<0.05). The area under the receiver operating characteristic curve was 0.944, the 95% confidence interval was 0.914-0.974, with a Yonden index of 0.779, sensitivity of 94.9%, specificity of 83%, and the cutoff value of 0.14. Conclusions:Multimodal non-drug treatment during induction of general anesthesia can effectively reduce the development of ED in the preschool children.

Comparison of efficacy of different drugs in reducing incidence of emergence agitation after tonsillectomy and adenoidectomy in pediatric patients: a network meta-analysis / 中华麻醉学杂志

Objective:To compare the efficacy of different drugs in reducing incidence of emergence agitation after tonsillectomy and adenoidectomy in the pediatric patients.Methods:Cochrane Library, PubMed, Web of Science, EMBASE, China National Knowledge Infrastructure, Wanfang and Chinese Biomedical Literature Databases were searched from inception to July 2023 for the randomized controlled trials involving interventions to reduce the incidence of emergence agitation after tonsillectomy and adenoidectomy in pediatric patients. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias in the included studies. STATA 17.0 software was used to conduct a network meta-analysis according to the frequency-ology framework.Results:Twenty randomized controlled trials were finally included, involving 1 687 patients. Compared with placebo, 10 interventions could reduce the incidence of emergence agitation in pediatric patients after tonsillectomy and adenoidectomy, and the order of probability was as follows: dexmedetomidine ( OR and 95% confidence interval [ CI] 0.13 [0.09-0.20]), ketamine ( OR and 95% CI 0.15 [0.08-0.26]), clonidine ( OR and 95% CI 0.15 [0.05-0.50]), tramadol ( OR and 95% CI 0.16 [0.04-0.61]), remazolam ( OR and 95% CI 0.17 [0.06-0.47]), afentanil ( OR and 95% CI 0.22 [0.08-0.62]), remifentanil ( OR and 95% CI 0.24 [0.12-0.48]), desocine ( OR and 95% CI 0.29 [0.12-0.69]), fentanyl ( OR and 95% CI 0.31 [0.19-0.52]) and propofol ( OR and 95% CI 0.46 [0.24-0.86]). Four interventions cloud reduce the usage rate of postoperative rescue drugs, and the probability was ranked as follows: dexmedetomidine ( OR and 95% CI 0.19 [0.11-0.32]), tramadol ( OR and 95% CI 0.20 [0.10-0.42]), ketamine ( OR and 95% CI 0.49 [0.28-0.86]) and fentanyl ( OR and 95% CI 0.49 [0.32-0.77]). One intervention cloud reduce the incidence of postoperative nausea and vomiting: dexmedetomidine ( OR and 95% CI 0.54 [0.31-0.94]). Conclusions:Dexmedetomidine provides the best effect in reducing the incidence of emergence agitation after pediatric tonsillectomy and adenoidectomy.

Malaria and artemisinin resistance: a bibliometric analysis

With roughly 50 % of the global population at risk for infection, malaria is one of the most serious public health problems in the world. This infection is caused by single-celled protozoa of the genus Plasmodium. By the turn of the century, the majority of antimalarial drugs were no longer effective against Plasmodium falciparum. However, one year after World Health Organization's final endorsement for the global use of ACTs, an appearance of artemisinin-resistant Plasmodium falciparum was seen in the border regions of Thailand and Cambodia and has since spread to other areas on the globe in subsequent years. The purpose of this work is to summarize the knowledge structure and trend of malaria and artemisinin resistance from 2012 to 2022. The VOS viewer application was used to bibliometrically analyze publications from 2012 to 2022. A total of 169 papers that discussed the keywords were used. VOS viewer application was used to produce maps based on the scientific data between the top authors and top terms in clusters. The research trend of artemisinin resistance and malaria was reported to be on the decline from 2019 to 2022. The bibliographic analysis offered an intellectual framework for the study area by identification of research groups and themes. The years with the most publications were 2015-2017, with 23 articles published each year. The most often used keywords in the research were artemisinin resistance (38 occurrences). The spread of artemisinin-resistant P. falciparum in significant regions of Southeast Asia threatens to destabilize malaria control globally. One of the most pressing global health concerns today is preventing artemisinin resistance from spreading to Africa, where the consequences for childhood mortality might be severe.

Treatment with insecticide and fungicide on the physiological quality of lentil seeds / Tratamento com inseticida e fungicida na qualidade fisiológica de sementes de lentilha

The low Brazilian productive index and the high demand have aroused interest in the cultivation of lentils, however the legume is little known and needs further studies. The objective of this study was to analyze and identify the effects of treatments with insecticides and fungicides on the physiological quality of lentil seeds, CA-1512 strain. The experiments were conducted in the seed laboratory in a completely randomized design with seven treatments and four replicates. Seed treatment with Thiophanate-methyl; Fluazinam® (180 ml) + Pyraclostrobin; Thiophanate-methyl; Fipronil® (150 ml) promoted higher levels of germination under accelerated aging, lower number of abnormal seedlings and longer lengths of shoot and radicle for the emergence in paper. Treatment with Carboxin; Thiram® (250 ml) + Imidacloprid® (150 ml) allowed a higher value in the first count of germination in sand, lower number of dead seeds under accelerated aging and longer root length, in the emergence in sand. Shoot length in the emergence in sand increased after seed treatment with Metalaxyl-M; Fludioxonil® (75 ml) + Pyraclostrobin; Thiophanate-methyl; Fipronil® (150 ml). Treatments with fungicides and insecticides considerably improved the physiological properties of the seeds, thus being able to guarantee greater phytosanitary qualities in the field, generating healthier seedlings and with protection against possible pests and diseases, and consequently guaranteeing greater productivity.

O baixo índice produtivo brasileiro e a alta demanda têm despertado o interesse no cultivo da lentilha, porém a leguminosa é pouco conhecida e necessita maiores estudos. Objetivou-se neste trabalho analisar e identificar tratamentos com inseticidas e fungicidas na qualidade fisiológica das sementes de lentilha, linhagem CA-1512. Os experimentos foram conduzidos no laboratório de sementes em delineamento inteiramente casualizado com sete tratamentos e quatro repetições. O tratamento de semente com Tiofanato-metílico; Fluazinam® (180 ml) + Piraclosrobina; Tiofanato-metílico; Fipronil® (150 ml) proporcionou índices mais elevados de germinação no envelhecimento acelerado, menor número de plântulas anormais e maior comprimento de parte aérea e radícula, na emergência em papel. O tratamento com Carboxina; Tiram® (250 ml) + Imidacloprido® (150 ml) possibilitou maior índice na primeira contagem de germinação em areia, menor número de sementes mortas no envelhecimento acelerado e maior comprimento de raiz, na emergência em areia. Já o comprimento da parte aérea, na emergência em areia, aumentou com o tratamento de semente Metalaxil-M; Fludioxonil® (75 ml) + Piraclosrobina; Tiofanato-metílico; Fipronil® (150 ml). Os tratamentos com fungicidas e inseticidas melhoraram consideravelmente as propriedades fisiológicas das sementes, podendo assim, garantir maiores qualidades fitossanitárias à campo, gerando plântulas mais sadias e com proteção para possíveis pragas e doenças, e consequentemente garantindo maiores produtividades.

Apesar de carregar "mental" em seu nome, no que concerne aos profissionais inseridos em serviços de atenção diária a portadores de transtornos mentais, não há tanto questionamento sobre os pressupostos teóricos que implicam a caracterização que qualifica e delimita o campo da saúde mental. O que é o "mental" da saúde mental? Com vistas a contribuir para a interdisciplinaridade dessa área de atuação, faremos uma análise da teoria de Terrence Deacon, biólogo evolutivo contemporâneo que estuda a emergência da vida e da mente, propondo essa discussão como um aspecto formativo essencial e pouco consolidado nas práticas em saúde mental Como conclusão, veremos como a visão do autor implica, para a saúde mental, uma abordagem na qual esta não pode ser pensada como ausente de aspectos normativos, subjetivos e ambientais.

Resumos Despite having "mental" in its name, as far as professionals engaged in daily services for persons with mental disorders are concerned, there is not much scrutiny about the theoretical assumptions involved in characterizing and delimiting the field of mental health. What is "mental" in mental health? In order to strengthen the interdisciplinary aspects of this field, we will carry out an analysis of the theory by Terrence Deacon, a contemporary evolutionary biologist who studies the emergence of life and mind, and will offer this discussion as an essential formative aspect as yet neglected in mental health practice. In conclusion, we will consider how Deacon's view entails an approach to mental health in which cannot be conceived devoid of normative, subjective and environmental aspects..

Bien que son nom contienne le mot « mental ¼, les professionnels qui travaillent dans les services de soins quotidiens pour les patients atteintes de troubles mentaux ne s'interrogent pas tellement sur les présupposés théoriques qui impliquent la caractérisation qui qualifie et délimite le domaine de la santé mentale. Qu'est-ce que le « mental ¼ de la santé mentale ? Afin de contribuer à l'interdisciplinarité de ce champ d'expertise, nous analyserons la théorie de Terrence Deacon, biologiste évolutionniste contemporain qui étudie l'émergence de la vie et de l'esprit, en proposant cette discussion comme un aspect formatif essentiel et peu consolidé dans les pratiques de santé mentale. Nous verrons comment la vision de l'auteur implique, pour la santé mentale, une approche dans laquelle elle ne peut être pensée comme absente des aspects normatifs, subjectifs et environnementaux.

A pesar de llevar "mental" en su nombre respecto de los profesionales que realizan servicios de atención diaria a las personas con trastornos mentales, no se cuestiona tanto los supuestos teóricos que implican la caracterización que califica y delimita el campo de la salud mental. ¿Qué es lo "mental" de la salud mental? Para contribuir a la interdisciplinariedad de esta área de especialización, haremos un anàlisis de la teoría de Terrence Deacon, biólogo evolutivo contemporáneo que estudia el surgimiento de la vida y de la mente, proponiendo esta discusión como un aspecto formativo esencial y poco consolidado en las prácticas de salud mental. En la conclusión, veremos cómo el autor da a la salud mental un enfoque en el que no se puede pensarlo sin tener en cuenta los aspectos normativos, subjetivos y ambientales..

Effects of Dolutegravir (DTG) on Survival, Pupariation and Emergence in Drosophila melanogaster: The Rescue Role of Brassica oleracea

The study aimed at determining the protective role of Brassica oleracea on dolutegravir-induced changes in Pupariation and Emergence of Drosophila melanogaster. D. melanogaster aged 3-5 days old were exposed to different concentrations (0.5 to 4 mg/ 5 g diet) of dolutegravir and B. oleracea extract (7.5–1000 mg/5 g diet) for 7 days to determine the lethal concentration (LC50). D. melanogaster were then exposed to the extract (50, 100, 200, and 400 mg/5 g diet) and controls (diet alone and vitamin C) to assess their effects on pupariation and emergence. A 14-day assay was also performed to evaluate the effect of the extract and toxicant (dolutegravir) on fly survival. The result showed a dose-dependent significant decrease (P < 0.05) and a dose-dependent significant increase (P < 0.05) in survival for D. melanogaster exposed to dolutegravir and the extract respectively, when compared to the control group. Results showed a delay in pupariation and decrease in mean pupariation in flies exposed to dolutegravir alone. An improvement in the same parameters was observed in D. melanogaster pre-treated with the extract before exposure to dolutegravir. D. melanogaster pre-treated with 200 and 400 mg extract per 5 g diet showed emergence that was comparable to those in the control groups. A significant decrease (P < 0.05) was observed in the groups exposed to 50 and 100 mg extract per 5 g diet, suggesting no protection at these doses. This study concludes that B. oleracea leaf extract, at certain concentrations, is able to protect against dolutegravir-induced changes in pupariation and emergence in D. melanogaster.
