Fluids in the treatment of diabetic ketoacidosis in children: A systematic review.

AIM: To determine the comparative effectiveness of fluid schemes for children with diabetic ketoacidosis (DKA). METHODS: We conducted a systematic review with an attempt to conduct network meta-analysis (NMA). We searched MEDLINE, EMBASE, CENTRAL, Epistemonikos, Virtual Health Library, and gray literature from inception to July 31, 2022. We included randomized controlled trials (RCTs) in children with DKA evaluating any intravenous fluid schemes. We planned to conduct NMA to compare all fluid schemes if heterogeneity was deemed acceptable. RESULTS: Twelve RCTs were included. Studies were heterogeneous in the population (patients and DKA episodes), interventions with different fluids (saline, Ringer's lactate (RL), and polyelectrolyte solution-PlasmaLyte®), tonicity, volume, and administration systems. We identified 47 outcomes that measured clinical manifestations and metabolic control, including single and composite outcomes and substantial heterogeneity preventing statistical combination. No evidence was found of differences in neurological deterioration (main outcome), but differences were found among interventions in some comparisons to normalize acid-base status (∼2 h less with low vs. high volume); time to receive subcutaneous insulin (∼1 h less with low vs. high fluid rate); length of stay (∼6 h less with RL vs. saline); and resolution of the DKA (∼3 h less with two-bag vs. one-bag scheme). However, available evidence is scarce and poor. CONCLUSIONS: There is not enough evidence to determine the best fluid therapy in terms of fluid type, tonicity, volume, or administration time for DKA treatment. There is an urgent need for more RCTs, and the development of a core outcome set on DKA in children.

Exploring tea and herbal infusions consumption patterns and behaviours: The case of Portuguese consumers.

Consumption of tea and herbal infusions (THIs) have a long history in traditional medicine and cultural practices. The health-promoting benefits attributed to THIs are considered influential factors in consumer choices. However, there is limited data on consumer choices and attitudes that might interfere with the positive effects associated with THIs consumption. The aim of this study was to investigate the consumption pattern and behavior of THIs consumers in Portugal, assessing the influence of socio-demographic factors on the selection of THIs products and consumer practices related to these beverages. An online survey was conducted, and from the collected data, 720 responses met the aim of the study and were further analyzed. Most of the respondents were female, 74.4%, belonging to the 40-60 age group (40.6%) and were medium consumers of THIs (47.2%). Green tea was the most consumed type among participants, and its consumption was associated not only with age but also with the pattern of THIs consumption. Despite that, participants preferred herbal infusions, with citronella, chamomile, and lemon verbena being the most consumed types. For certain types of herbal infusions, consumption was associated with age, while other types were preferred by moderate or heavy consumers. Most participants purchased THIs in supermarkets, registered trademark and brand stores, in the form of THIs bag. Light consumers use only bag, while medium/heavy consumers indicated the use of other forms. Almost half of the respondents admitted to not reading the information on product labels before consumption and using THIs after the expiry date, while only one-third of them declared paying attention to the label instructions. This study revealed the impact of socio-demographic factors as age on the consumption patterns and preferences of THIs of consumers. Of concern is the neglect of label usage among Portuguese consumers. This emphasizes the urgency of implementing interventions to guide proper label use and promote good consumption practices to ensure the quality of THIs products.

Intravenous iron infusions in pediatric patients: A retrospective review of efficacy and safety.

Pediatric iron deficiency anemia (IDA) is often treated with oral iron supplementation as the first-line therapy despite poor adherence. This single-institution retrospective chart review of pediatric patients was conducted to assess the safety, efficacy, and adherence of intravenous (IV) iron infusions compared to oral iron therapy in patients who had failed a trial of oral iron supplementation. We reviewed medical records of patients aged 1-21 with IDA who received at least one IV iron infusion at Cooper University Hospital between 2016 and 2021. Paired t-tests compared pre-infusion and post-infusion hematologic indices of hemoglobin (Hgb), mean corpuscular volume, red blood cell count, red cell distribution width, ferritin, total iron binding capacity, iron stores, and iron saturation. We compared adherence and adverse reactions to both oral iron supplementation and IV iron infusions using McNemar's test. A total of 107 subjects were included (mean age of 12.7 years). Hgb, ferritin, iron, and iron saturation between pre-infusion and post-final infusion significantly improved (p < 0.001). Hgb, ferritin, and iron improved when subcategorizing by race and etiology of IDA. Adherence to IV iron infusions (70.1%) was significantly greater than adherence to oral iron therapy (43.0%). There were also significantly fewer adverse effects with IV iron infusions (3.7%) compared to oral iron (77.9%). We demonstrated the safety, efficacy, and improved adherence of IV iron infusions compared to oral iron supplementation for treatment of pediatric IDA in patients who were unable to tolerate oral iron supplementation. Future studies could compare adherence to multiple doses of IV iron infusions in contrast with other single-dosing IV iron formulations.

Two versus Three Infusion Regimens of N-Acetylcysteine for Acetaminophen Overdose.

BACKGROUND: Acetaminophen overdose is a common clinical condition, often leading to liver toxicity. Current treatments involve the three-infusion N-Acetylcysteine (NAC) regimen (FDA-labeled), which may be complex, time-consuming, and need to be changed. An alternative uses two infusions instead, which offers possible advantages regarding simplicity and administration errors. This study sought to compare the respective efficacies and safety outcomes when treating acute acetaminophen overdose among children and adolescents. METHODS: At Montreal Children's Hospital, a retrospective study was conducted comparing pre-2003 FDA-labelled three-infusion NAC therapy with a two-infusion regimen. Information was collected regarding patient demographics, NAC administration details, errors, rates of hepatotoxicity, and adverse reactions, and the statistical test Chi-square test was employed to obtain the results. RESULTS: A total of 126 patients met the inclusion criteria. Of these patients, 65 received a two-infusion regimen, and 61 patients received the FDA-labeled regimen. The two-infusion group experienced significantly fewer administration errors (4 errors vs. 23 errors; p < 0.001), while the rates of hepatotoxicity between them were similar. There were no instances of liver transplantation or mortality due to either regimen. Adverse reactions occurred equally frequently between both regimens with no discernible difference-the meantime to administer NAC was 9 h for the two-infusion regimen and 8.5 h for FDA-labeled regimen groups, respectively. Three cases of hepatitis were successfully treated with timely NAC therapy, and no liver transplantation or mortality occurred. Adverse reactions, including anaphylactoid reactions, were observed in both groups but were resolved when temporarily stopped and restarted at a slower infusion rate. CONCLUSIONS: The two-infusion NAC regimen proved similar efficacy at protecting liver damage and improving patient outcomes compared to its FDA-labeled three-stage counterpart, with significantly fewer administration errors for this version of NAC treatment, suggesting potential advantages in terms of safety and simplicity. Future research should investigate larger cohorts and more variables to validate these results further and optimize the management of acetaminophen overdose cases; further investigation should focus on dosing strategies, personalized approaches, and long-term patient care in this context.

Implanted intrathecal drug delivery systems may be associated with improved survival in patients with cancer.

Background: Intrathecal Drug Delivery Systems (IDDS) are underused in the management of cancer-related pain despite evidence of both efficacy and survival benefit. There is currently limited evidence to indicate which patients might benefit most from IDDS. Aim: The aim of the study was to describe the baseline characteristics and survival outcomes of patients who accepted IDDS, patients who declined IDDS and patients who wished to go ahead with IDDS but whose condition deteriorated before they could do so. Design/participants: The survival data for 75 consecutive patients who had been offered intrathecal drug delivery were examined as part of a retrospective cohort study. Survival data was compared between three groups: those who accepted intrathecal drug delivery and went on to receive it (n = 41), those who accepted it but whose condition deteriorated before it commenced (n = 17) and those who declined this treatment modality (n = 17). Results: Patients who received IDDS survived significantly longer after assessment compared to those who declined IDDS (hazard ratio (HR) for the IDDS group relative to the declined group 0.29 (95% CI 0.16 to 0.53), and 0.23 (95% CI 0.12 to 0.44) after adjustment for gender and baseline functional status. In patients who accepted IDDS but who were unable to commence treatment, survival after assessment was not significantly different from those who declined the IDDS (HR for the deteriorated group relative to the declined group 1.28 (95% CI 0.65 to 2.53), and 0.80 (95% CI 0.65 to 2.53) after adjustment for gender and baseline functional status). Conclusion: In this retrospective analysis, an improvement in survival may be associated with patients who accept ongoing pain management with an implanted intrathecal drug delivery system compared to those patients who either declined intrathecal drug delivery or deteriorated before it could be commenced.

Efficacy of Continuous vs. Intermittent Administration of Cefepime in Adult ICU Patients with Gram-Negative Bacilli Bacteremia: A Randomized Double-Blind Clinical Study.

INTRODUCTION: The objective of this study was to compare the continuous infusion of cefepime with the intermittent infusion in patients with sepsis caused by Gram-negative bacilli (GNB). METHODS: Randomized 1:1 multicenter double-blinded placebo-controlled study with allocation concealment; multicenter study in the intensive care units of Colombia. Patients with sepsis, severe sepsis or septic shock, and GNB-suspected bacteremia. Cefepime was administered for 7 to 14 days over 30 m intermittently every 8 h over 24 h plus continuous saline solution (0.9%) (G1) or 3 g administered continuously plus saline solution every 8 h (0.9%) (G2). The percentage of clinical response at 3, 7, and 14 days, relapse at 28 days, and mortality at discharge were measured. RESULTS: The recruitment was stopped at the suggestion of the Institutional Review Board (IRB) following an FDA alert about cefepime. Thirty-two patients were randomized; 25 received the intervention, and GNB bacteremia was confirmed in 16 (9 G1 and 7 G2). Favorable clinical response in days 3, 7, and 14 was 88.8%, 88.8%, and 77.8% (G1) and was similar for G2 (85.7%). There were no relapses or deaths in G2, while in G1, one relapse and two deaths were observed. CONCLUSIONS: The results of this study support the use of cefepime for the treatment of Gram-negative infections in critically ill patients, but we could not demonstrate differences between continuous or intermittent administration because of the small sample size, given the early suspension of the study.

5% Dextrose in Ringer's Lactate versus 5% Dextrose Normal Saline as Maintenance Intravenous Fluid Therapy in Children - A Randomised Controlled Trial.

OBJECTIVES: To estimate the difference in serum chloride levels between children receiving 5% Dextrose in Ringer's Lactate (RLD5) vs. 5% Dextrose Normal Saline (DNS) and to estimate the incidence of dyselectrolytemia, hyperchloremic metabolic acidosis (HCMA), acute kidney injury (AKI) and all-cause mortality in both groups. METHODS: A randomised controlled trial was conducted in non-critically ill children aged 6 mo to 14 y, admitted between August 2021 and July 2022, requiring intravenous fluids. A sample size of 140 was estimated and randomised, with controls receiving 5% DNS and the intervention group receiving RLD5. Kidney function tests and blood gas analysis were done at admission, 24 h and 48 h after starting the maintenance IV fluid, and outcomes were analysed at 24 h and 48 h. Data was collected using a pre-designed data collection form that included demographic and clinical profile details, and outcomes were analysed using SPSS Version 20 software. RESULTS: Seventy-one children per group were enrolled. The mean chloride difference between the two groups at 24 and 48 h were 1.67 (p-value 0.03) and 2.78 (p-value 0.01), respectively. The incidence of AKI at 24 h and 48 h was 1.4% and 2.8% in the RLD5 group and 0% and 1.4% in the DNS group, respectively. At 24 h and 48 h, 2.8% and 2.8% of children had HCMA in the RLD5 group, and 14% and 4.2% had HCMA in the DNS group, respectively. There was no mortality in either group. CONCLUSIONS: Though clinically insignificant, there was a statistically significant difference in the serum chloride levels between the groups.

Endotracheal epinephrine at standard versus high dose for resuscitation of asystolic newborn lambs.

INTRODUCTION: Endotracheal (ET) epinephrine administration is an option during neonatal resuscitation, if the preferred intravenous (IV) route is unavailable. OBJECTIVES: We assessed whether endotracheal epinephrine achieved return of spontaneous circulation (ROSC), and maintained physiological stability after ROSC, at standard and higher dose, in severely asphyxiated newborn lambs. METHODS: Near-term fetal lambs were asphyxiated until asystole. Resuscitation was commenced with ventilation and chest compressions. Lambs were randomly allocated to: IV Saline placebo (5 ml/kg), IV Epinephrine (20 micrograms/kg), Standard-dose ET Epinephrine (100 micrograms/kg), and High-dose ET Epinephrine (1 mg/kg). After three allocated treatment doses, rescue IV Epinephrine was administered if ROSC had not occurred. Lambs achieving ROSC were monitored for 60 minutes. Brain histology was assessed for microbleeds. RESULTS: ROSC in response to allocated treatment (without rescue IV Epinephrine) occurred in 1/6 Saline, 9/9 IV Epinephrine, 0/9 Standard-dose ET Epinephrine, and 7/9 High-dose ET Epinephrine lambs respectively. Blood pressure during CPR increased after treatment with IV Epinephrine and High-dose ET Epinephrine, but not Saline or Standard-dose ET Epinephrine. After ROSC, both ET Epinephrine groups had lower pH, higher lactate, and higher blood pressure than the IV Epinephrine group. Cortex microbleeds were more frequent in High-dose ET Epinephrine lambs (8/8 lambs examined, versus 3/8 in IV Epinephrine lambs). CONCLUSIONS: The currently recommended dose of ET Epinephrine was ineffective in achieving ROSC. Without convincing clinical or preclinical evidence of efficacy, use of ET Epinephrine at this dose may not be appropriate. High-dose ET Epinephrine requires further evaluation before clinical translation.

Robotic Versus Open Hepatic Arterial Infusion Pump Placement for Unresectable Intrahepatic Cholangiocarcinoma.

BACKGROUND: Hepatic arterial infusion pump (HAIP) chemotherapy is an effective treatment for patients with unresectable intrahepatic cholangiocarcinoma (iCCA). HAIP chemotherapy requires a catheter inserted in the gastroduodenal artery and a subcutaneous pump. The catheter can be placed using an open or robotic approach. OBJECTIVE: This study aimed to compare perioperative outcomes of robotic versus open HAIP placement in patients with unresectable iCCA. METHODS: We analyzed patients with unresectable iCCA included in the PUMP-II trial from January 2020 to September 2022 undergoing robotic or open HAIP placement at Amsterdam UMC, Erasmus MC, and UMC Utrecht. The primary outcome was time to functional recovery (TTFR). RESULTS: In total, 22 robotic and 28 open HAIP placements were performed. The median TTFR was 2 days after robotic placement versus 5 days after open HAIP placement (p < 0.001). One patient (4.5%) in the robotic group underwent a conversion to open because of a large bulky tumor leaning on the hilum immobilizing the liver. Postoperative complications were similar-36% (8/22) after robotic placement versus 39% (11/28) after open placement (p = 1.000). The median length of hospital stay was shorter in the robotic group-3 versus 5 days (p < 0.001). All 22 robotic patients initiated HAIP chemotherapy post-surgery, i.e. 93% (26/28) in the open group (p = 0.497). The median time to start HAIP chemotherapy was 14 versus 18 days (p = 0.153). CONCLUSION: Robotic HAIP placement in patients with unresectable iCCA is a safe and effective procedure and is associated with a significantly shorter TTFR and hospital stay than open HAIP placement.

Carboplatin desensitization - simplified 4-step 2-bag method.

INTRODUCTION: Our cancer program adopted a method for carboplatin desensitization (4-step 2-bag method) that administers the same intensity of drug exposure with a simplified approach to product management in comparison to a published protocol (4-step 4-bag method). METHODS: The intensity of carboplatin administration for 1:1,000, 1:100, 1:10, and 1:1 dilutions and concomitant fluid administration were compared for the 4-step 2-bag (bags A, B) and 4-step 4-bag (bags 1, 2, 3, 4) methods. Pharmacy preparation of bags A and B is described. A succinct overview of the desensitization procedure is provided. Important considerations germane to pharmacy practice are presented. Chart review of patients who underwent carboplatin desensitization with the 4-step 2-bag method between 7/13/2021 and 11/22/2023 was performed to demonstrate institutional use. RESULTS: The 4-step 2-bag method delivers similar rates of drug intensity from start of desensitization to completion of the planned dose as the previously published 4-step 4-bag method. Accuracy of regimen-based dose administration is assured by infusion of bag B contents irrespective of infusion interruptions or rate changes necessitated by patient tolerance. Bag A provides the 1:1000 dilution in a pharmaceutically elegant manner using administration rates and volumes compatible with clinical practice. CONCLUSION: The 4-step 2-bag method for carboplatin desensitization administers controlled drug titration corresponding to 1:1000, 1:100, 1:10, and 1:1 dilutions for dose administration using two compounded admixture bags. Inaugural clinical use of the 4-step 2-bag method for carboplatin desensitization at our healthcare facility has proceeded with expected patient tolerance.

Artificial Intelligence Sensing: Effective Flavor Blueprinting of Tea Infusions for a Quality Control Perspective.

Tea infusions are the most consumed beverages in the world after water; their pleasant yet peculiar flavor profile drives consumer choice and acceptance and becomes a fundamental benchmark for the industry. Any qualification method capable of objectifying the product's sensory features effectively supports industrial quality control laboratories in guaranteeing high sample throughputs even without human panel intervention. The current study presents an integrated analytical strategy acting as an Artificial Intelligence decision tool for black tea infusion aroma and taste blueprinting. Key markers validated by sensomics are accurately quantified in a wide dynamic range of concentrations. Thirteen key aromas are quantitatively assessed by standard addition with in-solution solid-phase microextraction sampling followed by GC-MS. On the other hand, nineteen key taste and quality markers are quantified by external standard calibration and LC-UV/DAD. The large dynamic range of concentration for sensory markers is reflected in the selection of seven high-quality teas from different geographical areas (Ceylon, Darjeeling Testa Valley and Castleton, Assam, Yunnan, Azores, and Kenya). The strategy as a sensomics-based expert system predicts teas' sensory features and acts as an AI smelling and taste machine suitable for quality controls.

Extraction Optimization and Qualitative/Quantitative Determination of Bioactive Abietane-Type Diterpenes from Three Salvia Species (Common Sage, Greek Sage and Rosemary) by 1H-qNMR.

The objective of this study was the optimization of the extraction process and the qualitative and quantitative determination of the bioactive metabolites: 12-O-methylcarnosic acid (12MCA), carnosic acid (CA), carnosol (CS), 7-O-methyl-epi-rosmanol (7MER) and rosmanol (RO) in infusions, decoctions, turbulent flow extracts, tinctures and oleolites from three Salvia species: Salvia officinalis L. (common sage, SO), Salvia fruticosa Mill. (Greek sage, SF) and Salvia rosmarinus Spenn (syn Rosmarinus officinalis L.) (rosemary, SR), using Quantitative Proton Nuclear Magnetic Resonance Spectroscopy (1H-qNMR). Regarding the aqueous extracts, decoctions appeared to be richer sources of the studied metabolites than infusions among the three plants. For SR, the turbulent flow extraction under heating was the most efficient one. The optimum time for the preparation of decoctions was found to be 5 min for SF and SO and 15 min for SR. It is noteworthy that SR tinctures were not stable in time due to decomposition of the abietane-type diterpenes CA and CS because of the polar solvent used for their preparation. Contrary to this finding, the oleolites of SR appeared to be very stable. Olive oil as a solvent for extraction was very protective for the contained abietane-type diterpenes. A preliminary stability study on the effect of the storage time of the SF on the abietane-type diterpenes content showed that the total quantity of abietanes decreased by 16.51% and 40.79% after 12 and 36 months, respectively. The results of this investigation also demonstrated that 1H-qNMR is very useful for the analysis of sensitive metabolites, like abietane-type diterpenes, that can be influenced by solvents used in chromatographic analysis.

Outcomes associated with a variable rate insulin infusion diabetic ketoacidosis protocol.

AIMS: To relate adverse events with glucose correction rates in diabetic ketoacidosis (DKA) using variable rate intravenous insulin-infusions (VRIII). METHODS: Retrospective, observational study in adults with DKA who received insulin infusions between 2012 and 2017 at St Vincent's Hospital, Melbourne. Early correction of hyperglycaemia (<10 mmol/L) was evaluated for association with hypoglycaemia (<4.0 mmol/L), hypokalaemia (potassium <3.3 mmol/L) and clinical outcomes via regression analysis. RESULTS: The study involved 97 patients, with 93 % having type 1 diabetes. The mean age was 38 years, 47 % were women and 35 % were admitted to intensive care. Hypoglycaemia rates during 12 and 24 h of treatment were 6.2 % and 8.2 %, respectively with 58 % of patients recording their first BGL <10 mmol/L within 12 h and 88 % within 24 h. Ketone clearance time averaged at 15.6 h. Hyperglycaemia correction rates to <10 mmol/L were not different in those with/without hypoglycaemia at 12/24 h, in multivariate analysis including admission BGL. Hypokalaemia occurred in 40.2 % of patients and was associated with lower pH but not BGL correction rates. CONCLUSION: The VRIII protocol achieved early hyperglycaemia correction and ketoacidosis reversal with low hypoglycaemia risk. However, high hypokalaemia rates suggest the need for aggressive potassium replacement, especially in markedly acidotic patients.

Subcutaneous Bolus Infusions of Undiluted Levetiracetam for End-of-Life Patients: Two Cases.

We present two cases, in which end-of-life patients were inadvertently treated with bolus infusions of undiluted subcutaneous levetiracetam. The patients were treated for three and four days respectively. In both cases, the course of treatment was uneventful. Especially, no seizures, nor local irritation was observed. Administration of undiluted subcutaneous levetiracetam as intermittent bolus infusions by hand holds alluring properties for end-of-life patients. Amongst others reducing patient discomfort, increasing freedom of movement, and accessibility to essential seizure prophylaxis by eliminating the need for a syringe driver, thereby helping accommodate many patients wish to die in their own home. However, pharmacokinetics, efficacy, and safety, including the optimum dilution and administration time of the subcutaneous preparation remains to be determined in clinically controlled trials.

Rechallenges without desensitization following platinum-based chemotherapy reactions.

BACKGROUND: There is increasing interest in non-desensitization protocols as a potential way to reintroduce chemotherapy following hypersensitivity reactions (HSR). OBJECTIVE: To provide insight into the potential utility of non-desensitization reintroduction, particularly at institutions where allergy consultation may not be available. METHODS: For 70 patients with platinum HSR who underwent rechallenge with standard (≤2 hours), extended (1-bag, 1-step, 4-6 hours), or titrated (4-to-5-bag and -step, 6-7.5 hours) infusions between 1/2014 and 7/2019, demographics and clinical characteristics were reviewed and initial and breakthrough reactions (BTR) were graded using Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v5.0). Tolerance (no BTR) and completion (dose completed despite BTR) were compared using Fisher's exact test. RESULTS: Patients (mean [standard deviation] age 57 [13] years, initial HSR grade 2 [1]), were rechallenged with standard (n = 8), extended (n = 23), or titrated (n = 22) infusions after oxaliplatin HSR; and standard (n = 5) or titrated (n = 12) after carboplatin HSR. Tolerance and completion were higher for extended versus (vs) standard (tolerance-87%-vs-8%, p < 0.005; completion-96%-vs-38%, p < 0.005) and titrated versus standard (tolerance-76%-vs-8%, p < 0.005; completion-79%-vs-38%, p < 0.05) infusions. CONCLUSIONS: Extended and titrated infusions may increase reintroduction safety compared to standard infusions. Further investigation into extended infusions may provide a safe alternative to standard infusions in patients who may not have access to desensitization at their institution.

Comparative phytochemical analysis of cultivated and wild Sideritis raeseri Boiss. & Heldr. subsp. raeseri infusions.

The present study focuses on the chemical composition of the infusions of Sideritis raeseri subsp. raeseri from cultivated and wild populations using NMR, LC-DAD, LC-HRESIMS, and GC-MS techniques, to reveal possible differences. Mainly carbohydrates, flavonoids, and phenylethanoid glycosides were detected in the 1H-NMR spectra of both infusions. In the GC-MS analysis, carbohydrates were shown to be the main constituents in both infusions. Caffeic acid was found in traces only in the cultivated sample, while quinic and chlorogenic acids were detected in both samples. Further investigation by LC-HRESIMS unveiled the same constituents with only slight differences in the amounts. Although the Sideritis samples originated from wild and cultivated populations, similar metabolic profiles were observed in the infusions.

Examining the effect of training with a teaching for understanding framework on intravenous therapy administration's knowledge, performance, and satisfaction of nursing students: a non-randomized controlled study.

BACKGROUND: Nursing students require improvement in their intravenous infusion therapy management skills, yet traditional training models possess deficiencies. The Teaching for Understanding (TfU) Framework can enhance the teaching-learning process and support quality education. Therefore, utilizing TfU framework for training may promote the performance of nurses. METHODS: Utilizing a non-synchronized design, 102 nurses were recruited using a convenience sampling method. Fifty-one student nurses from August 2019 to January 2021 were designated as the control group, and 51 student nurses from February 2021 to July 2022 were included as the intervention group. The control group received traditional teaching methods, while the intervention group was trained based on TfU framework. The impact was gauged through medical education environment perception, theory and practice assessments, and learning satisfaction surveys. RESULTS: After the training, there was no significant difference between the control group and the intervention group in the theory assessment. However, the practice assessment scores of the intervention group were significantly higher than those of the control group. Compared with the control group, the learning satisfaction scores of the trained nurses in the intervention group were significantly higher, exhibiting significant differences, particularly in communication ability, teamwork cooperation, summing up capability, and interest in learning improvement. Furthermore, the scores of the learning perceptions, atmosphere, social self-perceptions, and total scores of the intervention group were significantly higher. CONCLUSION: Training using TfU framework can heighten students' understanding and command over knowledge and skills, fuel their learning fervor, and enhance their communication and collaboration abilities. TfU framework should be disseminated in medical education to improve the quality of education.

Development of a model to predict vancomycin serum concentration during continuous infusion of vancomycin in critically ill pediatric patients.

Vancomycin is a frequently used antibiotic in intensive care units, and the patient's renal clearance affects the pharmacokinetic characteristics of vancomycin. Several advantages have been reported for vancomycin continuous intravenous infusion, but studies on continuous dosing regimens based on patients' renal clearance are insufficient. The aim of this study was to develop a vancomycin serum concentration prediction model by factoring in a patient's renal clearance. Children admitted to our institution between July 1, 2021, and July 31, 2022 with records of continuous infusion of vancomycin were included in the study. Sex, age, height, weight, vancomycin dose by weight, interval from the start of vancomycin administration to the time of therapeutic drug monitoring sampling, and vancomycin serum concentrations were analyzed with the linear regression analysis of the mixed effect model. Univariable regression analysis was performed using the vancomycin serum concentration as a dependent variable. It showed that vancomycin dose (p < 0.001) and serum creatinine (p = 0.007) were factors that had the most impact on vancomycin serum concentration. Vancomycin serum concentration was affected by vancomycin dose (p < 0.001) and serum creatinine (p = 0.001) with statistical significance, and a multivariable regression model was obtained as follows: Vancomycin serum concentration (mg/l) = -1.296 + 0.281 × vancomycin dose (mg/kg) + 20.458 × serum creatinine (mg/dl) (adjusted coefficient of determination, R2 = 0.66). This prediction model is expected to contribute to establishing an optimal continuous infusion regimen for vancomycin.

Postoperative pain management using an intravenous combination of ibuprofen and acetaminophen compared with acetaminophen alone after thyroidectomy: A prospective randomized controlled trial.

BACKGROUND: Multiple medications are more effective than single agents for postoperative pain management. We investigated the analgesic effects of an intravenous combination of acetaminophen and ibuprofen immediately after thyroidectomy. METHODS: In this double-blind clinical trial, 62 patients who underwent thyroidectomies were randomized to either the treatment (1000 mg acetaminophen, 300 mg ibuprofen) or control (1000 mg acetaminophen) group. Postoperative pain intensity was assessed using the visual analog scale (VAS) 0, 15, and 30 min after recovery room admission. Opioid rescue consumption was also recorded. RESULTS: The VAS scores were significantly lower in the treatment than in the control group 15 [3 (2-4.3) vs. 5 (3-6); p = 0.015] and 30 [3 (2-4.3) vs. 4 (3-5); p = 0.018] min after recovery room admission, as were the opioid rescue dose requirements (p = 0.033). CONCLUSIONS: Combined intravenous acetaminophen and ibuprofen may be better than acetaminophen alone for immediately acute postoperative pain after thyroidectomy.

Pharmacokinetics and pharmacodynamics across infusion rates of intravenously administered nipocalimab: results of a phase 1, placebo-controlled study.

Introduction: Nipocalimab is a high-affinity, fully human, aglycosylated, effectorless, immunoglobulin G (IgG) 1 monoclonal antibody that targets the neonatal Fc receptor (FcRn), decreases systemic IgG including autoantibodies, and is under development in several IgG autoantibody- and alloantibody-mediated diseases, including generalized myasthenia gravis, chronic inflammatory demyelinating polyneuropathy, maternal-fetal medicine, and multiple other therapeutic areas. An initial phase 1 study with single and multiple ascending doses of nipocalimab infused intravenously (IV) over 2 h demonstrated dose-dependent serum pharmacokinetics and IgG reductions, with an adverse event (AE) profile comparable to placebo. Methods: The current investigation evaluates the safety, tolerability, pharmacokinetics, and pharmacodynamics of single doses of nipocalimab across various IV infusion rates in a randomized, double-blind, placebo-controlled, sequential-dose study. Forty participants were randomized to receive nipocalimab 30 mg/kg over 60, 30, 15 or 7.5 min (0.5, 1, 2, or 4 mg/kg/min); nipocalimab 60 mg/kg over 15 min (4 mg/kg/min); or matching placebo. Results: At doses up to 60 mg/kg and infusion rates up to 4 mg/kg/min (maximum clinically feasible rate), single doses of nipocalimab were tolerable, with 12 (40%) participants experiencing AEs across nipocalimab cohorts compared with 1 (10%) participant in the placebo cohort. AEs deemed treatment related occurred in 6 (20%) participants receiving nipocalimab and 1 (10%) participant receiving placebo. None of the AEs were severe, and no participants discontinued treatment due to AEs. Nipocalimab provided consistent, dose-dependent serum pharmacokinetics and IgG reductions, regardless of infusion rate. Discussion: This study supports the use of shortened durations of nipocalimab infusion for future studies.
