RESUMEN

In vivo studies offer a detailed understanding of organism functioning, surpassing the insights provided by in vitro studies. These experiments are crucial for comprehending disease emergence, progression, and associated mechanisms in humans, as well as for developing treatments. When choosing experimental models, factors such as genomic similarity, physiological relevance, ethical appropriateness, and economic feasibility must be considered. Standardized protocols enhance the reliability, and reproducibility of scientific methods, promoting the assessment of research in the scientific literature. Researchers conducting embryo studies should establish and document standardized protocols for increased data comparability. Standardization is vital for scientific validity, reproducibility, and comparability in both in vivo and in vitro studies, ensuring the accuracy and reliability of experimental results and advancing scientific knowledge.

RESUMEN

This critique evaluates the systematic review and meta-analysis titled "Local anesthesia with sedation and general anesthesia for the treatment of chronic subdural hematoma." The study provides valuable insights into anesthesia techniques' effectiveness in managing this condition but has limitations, including selection bias, heterogeneity among cases, lack of standardized protocols, and retrospective design. Despite these limitations, the review contributes to understanding chronic subdural hematoma management but underscores the need for future research to address these shortcomings.

RESUMEN

BACKGROUND AND PURPOSE: Tonsillectomy procedures are commonly performed worldwide. At our academic tertiary care facility, we perform approximately 1000 tonsillectomy procedures annually. We have found inconsistent pain management strategies in pediatric tonsillectomy patients have contributed to variability in postoperative complications and the number and types of postoperative pain medications required in the Post Anesthesia Care Unit (PACU). This project aimed to assess the impact of implementing a standardized perioperative pain management protocol on reducing postoperative complications in pediatric patients who underwent a tonsillectomy procedure. METHODS: A pre-post-intervention design was utilized, comparing characteristics and outcomes of pediatric patients for whom a standardized perioperative pain management protocol was implemented over a 12-week period compared to those who did not. The standardized perioperative pain management protocol was utilized intraoperatively by the anesthesiologists, nurse anesthetists, and residents. A Qualtrics survey was used by the Post Anesthesia Care Unit (PACU) nurses to gather data as they cared for patients who underwent tonsillectomy. Four outcomes were measured: (1) postoperative pain medication administration, (2) rate of postoperative respiratory complications, (3) rate of adherence, and (4) usability of a standardized pain management protocol. Data were compared between pre and post-implementation groups. RESULTS: During the quality improvement project, 180 children underwent tonsillectomy, with 81 in the control group and 99 in the intervention group. The median age did not differ between groups. The control group had higher postoperative opioid medication usage (93.8% vs. 54.5%) and a higher number of opioids administered in the recovery room. Postoperative IV fentanyl was reduced in the intervention group (49.4% vs. 28.3% in the intervention, p = .004). Respiratory interventions were more frequent in the control group (24.7% vs. 7.1%), with increased respiratory team activation. Respiratory team activation in the Post Anesthesia Care Unit (PACU) includes a 511 page for anesthesia provider assistance. Respiratory interventions included bag-mask ventilation, lidocaine, propofol or succinylcholine administration, and reintubation. The intervention group had 100% adherence to the pain management protocol, and providers found it easy to use. CONCLUSION: The quality improvement project highlighted notable improvements in the intervention group for whom a standardized perioperative pain management protocol was used, including reduced opioid medication administration, lower incidence of respiratory interventions, and high adherence to the pain management protocol. These findings underscore the effectiveness and feasibility of standardized protocols in enhancing patient outcomes.

RESUMEN

The use of standardized imaging protocols is paramount in order to facilitate comparable, reproducible images and, consequently, to optimize patient care. Standardized MR protocols are lacking when studying head and neck pathologies in the pediatric population. We propose an international, multicenter consensus paper focused on providing the best combination of acquisition time/technical requirements and image quality. Distinct protocols for different regions of the head and neck and, in some cases, for specific pathologies or clinical indications are recommended. This white paper is endorsed by several international scientific societies and it is the result of discussion, in consensus, among experts in pediatric head and neck imaging.

RESUMEN

PURPOSE: To define and develop a model of excellence for the clinical management of diabetic macular edema (DME) patients in a real-world setting. METHODS: A multidisciplinary joint commission (5 ophthalmologists, 1 nurse, and 1 pharmaceutic) established a series of preliminary recommendations based on clinical guidelines and DME activity results from 8 Pilot Hospitals (PH). These were validated by members of each PH and a group of DME patients in discussion workshops. Thus, the validated guideline (VG) took into consideration different aspects, namely, main core points (ranging 0-100), criteria, and indicators. Finally, each PH own setting was compared to the VG in order to settle down a starting point to clinical excellence. RESULTS: Mean PH score was 51.5 (range 30-65). As compared to their maximum, main points that showed best scores were Clinical Guidelines and Protocols (78%) and Portfolio of Services (73%). Topics reaching close to 50% scoring included Resources (55%), Innovation (54%), Care Process (53%), Organization (52%), and Leadership (50%). Lowest scores were observed in the Strategic Alliances (46%) and Staff (37%) points. CONCLUSIONS: Analysis of each PH by the VG delivered a global vision of the starting situation, especially focused in the identification of the different improvement areas. In order to further extend this model into the Public Health System, the effect of implementing it in different hospitals should be assessed to analyze its impact on daily clinical practice and health economics.

RESUMEN

BACKGROUND: In patients requiring gastrostomies, ventriculoperitoneal (VP) shunts are a frequently encountered comorbidity. The objective of this study is to evaluate the postoperative management of children with VP shunts that undergo laparoscopic gastrostomy placement and determine their incidence of complications. MATERIALS AND METHODS: Children 18 y old or younger who underwent laparoscopic gastrostomy placement at a freestanding academic children's hospital between January 2014 and October 2016 were reviewed. Data collected included demographics, management, and outcomes. Patients were compared based on their presence of a VP shunt before laparoscopic gastrostomy. Statistical analysis was performed using chi square, Fisher's exact, and Wilcoxon rank-sum tests. RESULTS: We reviewed the medical records of 270 children that underwent laparoscopic gastrostomy placement by 15 pediatric surgeons. Of these, 9% (25) had a previously placed VP shunt. In comparing patients with a VP shunt with those without a VP shunt, there was no significant difference in median age (4 versus 3 y, P = 0.92), gender (48% versus 51% males, P = 0.80), body mass index (15 versus 16, P = 0.69), preoperative diet (48% versus 47% nasogastric tube dependent, P = 0.60), or procedure time (43 versus 42 min, P = 0.37). The postoperative management of these children was similar: day of initiation of postoperative feeds (84% versus 73% on postoperative day #1, P = 0.70), method of initiation of feeds (60% versus 55% continuous, P = 0.25), and type of initial feeds (83% versus 71% Pedialyte, P = 0.24). Similarly, there was no difference in hospital length of stay, return to the emergency department, or postoperative complications within 90 d (P > 0.05). CONCLUSIONS: Children with ventriculoperitoneal shunts do not have a higher rate of immediate complications after laparoscopic gastrostomy placement and may be managed similar to other children in the postoperative period.

RESUMEN

End-organ disease caused by CMV is a significant cause of morbidity and mortality in pediatric SOT recipients. Pediatric transplant centers have adopted various approaches for CMV disease prevention in this patient population. We observed significant practice variation in CMV testing, prophylaxis, and surveillance across SOT groups in our center. To address this, we implemented evidence-based standardized protocols and measured outcomes pre- and post-implementation of these protocols. We performed retrospective chart review for SOT recipients from 2009 to 2014 at Boston Children's Hospital. Using descriptive statistics, we measured practice improvement in provision of appropriate prophylaxis, occurrence of neutropenia and associated complications, and occurrence of CMV DNAemia and CMV disease pre- and post-intervention. The pre- and post-intervention periods included 141 and 109 patients, respectively. With the exception of kidney transplant recipients, provision of appropriate valganciclovir prophylaxis improved across SOT groups post-intervention (P < .01). Occurrence of >1 episode of neutropenia was greater in the preintervention period (30% vs 10%, P < .001). In both periods, neutropenia was associated with few episodes of invasive infections. The occurrence of CMV disease did not differ and was overall low. However, due to routine surveillance a significantly greater number of asymptomatic CMV DNAemia episodes were identified and treated in the post-intervention period. Implementation of standardized prevention protocols helped to improve the provision of appropriate prophylaxis to patients at risk for CMV acquisition, increased the diagnosis and treatment of asymptomatic CMV DNAemia, and decreased episodes of recurrent neutropenia in patients receiving prophylaxis.

RESUMEN

Nurses at a pediatric hospital identified the liberal utilization of deep nasopharyngeal (NP) suction as the primary airway clearance modality in young children with bronchiolitis. This invasive practice lacked supporting evidence and a standardized approach. Nurses created an interdisciplinary team to develop a less invasive airway clearance protocol. Data from 2years, both pre and post protocol implementation, were analyzed. An 11% decrease in deep NP suctioning resulted in improved or unchanged balancing measures and perceptions of quality of care.

RESUMEN

BACKGROUND: In the coming years, a significant increase in the number of computed tomography coronary angiographies (CCTA) is expected, leading to an additional burden on existing structures. OBJECTIVES: Discussion of effective processes and patient preparation in the context of high-volume CCTA. MATERIALS AND METHODS: The relevance of patient education and optimized workflows in clinical practice, including pharmacological heart rate control and vasodilation. RESULTS: To conduct resource-efficient and effective patient examinations, comprehensive and clear patient education is crucial. This can be provided to the patient during scheduling or delivered digitally, so that the patient arrives with a thorough understanding of the examination process. In addition, targeted optimization of workflows tailored to CCTA is important. For high image quality, the administration of ß­blockers is necessary in most cases. This can be done intravenously to save time. The administration of nitrates immediately before the examination is recommended by current guidelines for all patients without contraindications and is ideally applied sublingually shortly before the examination. CONCLUSION: The anticipated increase in CCTA will significantly strain existing structures not only in terms of reporting. Especially standardized and structured workflows pre- and periprocedurally are essential for handling a high number of examinations, while maintaining sufficient image quality in clinical practice.

RESUMEN

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a widely utilized treatment for various hematological diseases. While selection criteria for unrelated donors are well established, there is a lack of consistency and standardization in the selection of related donors. This study investigated the current approach of hematologists to the selection of related donors at Turkish HSCT centers. The study employed a cross-sectional survey design, distributing a self-administered questionnaire to 95 adult and pediatric transplantation centers in Türkiye to investigate their approaches to related donor selection for allo-HSCT. The questionnaire collected data on various topics including the center's experience in performing allo-HSCT, patient groups treated, number of allo-HSCT procedures conducted between 2015 and 2021, preferences for related donors, considerations in related donor selection (such as sex and past pregnancies), guidelines utilized for related donor selection, upper age limit for related donors, and the use of specialized advanced analyses for elderly donors. The response rate to the survey was 38.9%. Variability was observed across centers in terms of sex consideration and the impact of past pregnancies on related female donor rejection. Different guidelines were employed for related donor selection, with the European Bone Marrow Transplantation guidelines being the most commonly used. Regarding the upper age limit for related donors, 8.1% of centers accepted an upper age limit of 55 years, 48.7% preferred an upper age limit of 65 years, and 43.2% selected related donors aged 65 and above. The lack of standardized guidelines for related donor selection in HSCT centers leads to variability in criteria and potential risks. Collaboration among centers is essential to establish consensus and develop standardized protocols.

RESUMEN

PURPOSE: The purpose of this study was to (a) examine the interprofessional relationship between radiologists and speech-language pathologists (SLPs), and (b) explore viewpoints and practice patterns of each profession regarding a videofluoroscopic swallow study (VFSS). METHODS: This IRB approved study utilized an online survey developed by the authors to gather information from radiologists and SLPs who currently perform videofluoroscopic swallow studies (VFSS) for the evaluation of swallow function. Surveys were primarily distributed through the American Speech-Language-Hearing Association's (ASHA) Special Interest Group 13 (Swallowing and Swallowing Disorders) forum, through LinkedIn and email networking among professional radiology-focused businesses and organizations (Bracco Diagnostics, Inc., Society of Abdominal Radiology), and via social media (e.g. Facebook). The survey consisted of 7 demographic questions and 15 practice-related items, using a modified Likert scale and multiple-choice items to assess agreement with statements regarding VFSS procedures and opinions on professional roles. RESULTS: Radiologists and SLPs differed significantly (p < 0.05) in practices regarding nearly all items surveyed, including preferences on: esophageal sweep, anteroposterior view, fluoroscopy time limitation, termination following an aspiration event, frame rate, as well as in defining the primary role of the SLP, the primary purpose of a VFSS, the most valuable piece of information obtained from a VFSS, and training requirements. Radiologists and SLPs agreed that a standardized protocol should exist for VFSS. CONCLUSIONS: Radiologists and SLPs differ in their practice patterns and opinions on the roles of team members in the performance of VFSS. However, both radiologists and SLPs agree that a standardized protocol for VFSS should exist.

RESUMEN

BACKGROUND: Diabetic ketoacidosis (DKA) is a common acute life-threatening complication of poorly controlled diabetes mellitus contributing to considerable mortality and morbidity. Use of standardized treatment protocols improves patient outcomes in the emergency department (ED) for many conditions, but variability in adult DKA treatment protocols has not been assessed across EDs. In this study, we compared DKA treatment protocols from adult EDs across Canada to highlight inconsistencies in recommended DKA management. METHODS: ED staff in Canada were solicited for their treatment protocols used to guide acute ED DKA management. Information regarding initial fluid resuscitation and maintenance fluid, potassium replacement, insulin therapy and bicarbonate administration was abstracted from each protocol, collated in a table and compared. RESULTS: Thirty-six unique protocols were obtained representing 85 institutions (40 urban and 45 rural, with a 65.1% response rate) across Canada, with no protocol use for 4 urban centres. Similarities in protocols included the intravenous insulin infusion rate and instructions for switching to subcutaneous insulin. Variability was noted in the rate, amount and type of fluid bolus given (0.5 to 2 L of normal saline or Ringer's lactate over 15 minutes to 2 hours), the criteria determining the amount, potassium supplementation at normo/hypokalemic ranges, when to add dextrose to maintenance fluid, insulin bolus inclusion and bicarbonate administration. CONCLUSIONS: This is the first comparison of adult DKA treatment protocols in Canada. Although several common approaches were identified, variability was found in initial fluid boluses, initial insulin bolus and role of bicarbonate, necessitating further study to ensure local DKA protocols reflect current evidence-based best practices for optimal patient clinical outcomes.

RESUMEN

PURPOSE: Standardized protocols have been shown to improve outcomes in several pediatric surgical conditions. We implemented a multi-disciplinary gastroschisis practice bundle at our institution in 2013. We sought to evaluate its impact on closure type and early clinical outcomes. METHODS: We performed a retrospective review of uncomplicated gastroschisis patients treated at our institution between 2008-2019. Patients were divided into two groups: pre- and post-protocol implementation. Multivariate logistic regression was used to compare closure location, method, and success. RESULTS: Neonates (pre-implementation n = 53, post-implementation n = 43) were similar across baseline variables. Successful immediate closure rates were comparable (75.5% vs. 72.1%, p = 0.71). The proportion of bedside closures increased significantly after protocol implementation (35.3% vs. 95.4%, p < 0.01), as did the proportion of sutureless closures (32.5% vs. 71.0%, p < 0.01). Median postoperative mechanical ventilation decreased significantly (4 days IQR [3, 5] vs. 2 days IQR [1, 3], p < 0.01). Postoperative complications and duration of parenteral nutrition were equivalent. After controlling for potential confounding, infants in the post-implementation group had a 44.0 times higher odds of undergoing bedside closure (95% CI: 9.0, 215.2, p < 0.01) and a 7.7 times higher odds of undergoing sutureless closure (95% CI: 2.3, 25.1, p < 0.01). CONCLUSIONS: Implementing a standardized gastroschisis protocol significantly increased the proportion of immediate bedside sutureless closures and decreased the duration of mechanical ventilation, without increasing postoperative complications. Level of Evidence III Type of Study Retrospective comparative study.

RESUMEN

Benznidazole (BZ) is a first-line drug for the treatment of Chagas disease; however, it presents several disadvantages that could hamper its therapeutic success. Multiparticulate drug delivery systems (MDDS) are promising carriers to improve the performance of drugs. We developed BZ-loaded MDDS intended for improving Chagas disease therapy. To assess their efficacy and safety, Trypanosoma (T) cruzi infected BALB/c mice were orally treated with free BZ or BZ-MDDS at different regimens (doses of 50 and 100 mg/kg/day, administered daily or at 2- or 5-days intervals) and compared with infected non-treated (INT) mice. At 100 mg/kg/day, independent of the administration regimen, both treatments were able to override the parasitemia, and at 50 mg/kg/day significantly reduced it compared to INT mice. BZ-MDDS at a dose of 100 mg/kg/day administered every 5 days (BZ-MDDS 100-13d) induced the lowest cardiac parasite load, indicating an improved efficacy with lower total dose of BZ when loaded to the MDDS. Reactive oxygen species produced by leukocytes were higher in INT and mice treated with BZ at 50 mg/kg/day compared to 100 mg/kg/day, likely because of persistent infection. BZ-MDDS treatments markedly reduced heart and liver injury markers compared to INT mice and those receiving the standard treatment. Therefore, BZ-MDDS exhibited enhanced activity against T. cruzi infection even at lower doses and reduced administration frequency compared to free BZ while increasing the treatment safety. They likely avoid undesired side effects of BZ by keeping a sustained concentration, avoiding plasmatic drug peaks. BZ-MDDS evidenced significant improvements in experimental Chagas disease treatment and can be considered as a potential improved therapeutic alternative against this illness.

RESUMEN

Here we introduce a series of behavioural tasks to assess inter-individual variability in behaviours exhibited by the cephalopod mollusc Octopus vulgaris. We propose that, by using octopus' predatory behavioural response, it is possible to measure: (1) the ability to adapt to the captive condition (acclimatization), (2) the response towards novel stimuli (neophobia), (3) the capability of social learning, (4) the ability of solving problems (problem solving), and (5) the response to artificial stimuli (preferences, individual learning). To assure comparability and reproducibility of results, this battery of tests is here applied to a large sample of individuals in standardized experimental conditions. Such battery of tests serves as an in vivo screening that should be adopted not only to investigate cognitive abilities in specific behavioural domains, but also to monitor the welfare status of animals under captivity, thus to check sensory functions as well as motor abilities in other investigations within the fields of biology and neuroscience. Our aim was to provide a reliable tool to exploit this animal species for research in different fields.

RESUMEN

PURPOSE: To review current management and outcomes of ingested batteries and develop a clinical management algorithm. METHODS: Children <18years old who ingested a battery between 1/2011 and 9/2016 at two tertiary care children's hospitals were reviewed. Demographics, imaging, management and outcomes were analyzed using descriptive statistics, Chi-square and Wilcoxon Rank-sum tests. RESULTS: There were 180 battery ingestions. The median age was 3.9 (range 0.7-18) years, with 78 (43%) males. The most common symptoms were abdominal pain (17%) and nausea/vomiting (14%). Diagnosis was confirmed with plain radiographs in 170 (94%) patients. Locations on imaging were: stomach (37%), small bowel (24%), esophagus (18%), colon (11%), and non-specific location past the gastroesophageal junction (9%). Treatment was dictated by five different subspecialties including surgery (35%), gastroenterology (25%), emergency medicine (19%), primary care/emergency with a consulting service (13%), and otolaryngology (8%). All esophageal batteries (n=33) had an intervention. Interventions included fluoroscopic balloon extraction (6 attempted, 33% retrieval rate), rigid esophagoscopy (26 attempted, 96% retrieval rate), and EGD (6 attempted, 83% retrieval rate). For batteries distal to the gastroesophageal junction 16 (11%) patients had an intervention. Interventions included EGD (13 patients, 69% retrieval), colonoscopy (1 patient, successful retrieval), and abdominal surgery in two patients. CONCLUSION: Isolated batteries that pass the gastroesophageal junction rarely require intervention and can be managed conservatively. Given the variability in managing these patients, we developed an evidence based algorithm. LEVEL OF EVIDENCE: Level 2. STUDY TYPE: Retrospective Study.

RESUMEN

On-spot persistence, space occupancy, and recovery after damage are key plant functions largely understudied. Traits relevant to these functions are difficult to assess because of their relationships to plant modularity. We suggest that developing collection protocols for these traits is feasible and could facilitate their inclusion in global syntheses.

RESUMEN

PURPOSE: The objective of this study was to evaluate postoperative feeding regimens after laparoscopic gastrostomy placement and their effect on outcomes. METHODS: Children 18 years of age or younger, who underwent laparoscopic gastrostomy placement at a tertiary-care academic children's hospital between January 2014 and October 2016, were reviewed. Data collected included patient characteristics, postoperative feeding regimen, and clinical outcomes. Statistical analysis was performed using Chi-square, Fisher's exact, and Wilcoxon Rank-Sum tests. RESULTS: We reviewed the medical records of 270 children that underwent laparoscopic gastrostomy placement by 15 pediatric surgeons. The median age was 2.7 (interquartile range [IQR], 0.7-9.6) years, and 50% (n = 136) were male. The median body mass index was 15.5 (IQR, 14.0-17.5). Complications within 90 days included: granulation tissue (34%), leakage (17%), dislodgement (14%), and skin and soft-tissue infection (9%). Two patients returned to the operating room, 1 for a dislodged tube, and another for a volvulus within 10 days of gastrostomy tube placement. A subset analysis of outpatients that underwent elective laparoscopic gastrostomy placement showed variation in the day of initial feeds (0-2 postoperative days [POD]), method of initial feeds (continuous versus bolus) and choice of initial feeds (Pedialyte versus formula/breast milk). There was a significant difference in median hospital length of stay for early versus late initiation of feeds (POD 0: 2.1 days versus POD ≥1: 3.1 days, P < .01) without a difference in postoperative complications. CONCLUSION: There is substantial variation in the postoperative feeding regimen after laparoscopic gastrostomy. Initiation of early postoperative feeds may result in decreased length of stay without increasing complications.

RESUMEN

OPINION STATEMENT: Multiple sclerosis (MS) is an immune-mediated disease affecting the central nervous system (CNS). Magnetic resonance imaging (MRI) has long been recognized as an important tool in the diagnosis of MS. It is increasingly recognized that in addition to its role in diagnosis, MRI can play a key role as a noninvasive tool for prognostication, disease monitoring, assessment of treatment efficacy, and safety monitoring of disease-modifying therapies (DMTs). A confluence of factors, including increased availability of MRI, development of improved MRI techniques, and increased availability of DMTs have contributed to the expanding role of MRI in MS clinical care. As the clinical use of MRI in MS expands, it is important that MRI protocols amongst clinical centers are standardized. Here, we summarize recent evidence supporting the use of MRI in clinical practice, summarize various clinical guidelines and recommendations for the use of MRI in MS disease monitoring, and provide our recommendations for standardized MRI protocols.

RESUMEN

Biodiversity-ecosystem functioning (BEF) research has extended its scope from communities that are short-lived or reshape their structure annually to structurally complex forest ecosystems. The establishment of tree diversity experiments poses specific methodological challenges for assessing the multiple functions provided by forest ecosystems. In particular, methodological inconsistencies and nonstandardized protocols impede the analysis of multifunctionality within, and comparability across the increasing number of tree diversity experiments. By providing an overview on key methods currently applied in one of the largest forest biodiversity experiments, we show how methods differing in scale and simplicity can be combined to retrieve consistent data allowing novel insights into forest ecosystem functioning. Furthermore, we discuss and develop recommendations for the integration and transferability of diverse methodical approaches to present and future forest biodiversity experiments. We identified four principles that should guide basic decisions concerning method selection for tree diversity experiments and forest BEF research: (1) method selection should be directed toward maximizing data density to increase the number of measured variables in each plot. (2) Methods should cover all relevant scales of the experiment to consider scale dependencies of biodiversity effects. (3) The same variable should be evaluated with the same method across space and time for adequate larger-scale and longer-time data analysis and to reduce errors due to changing measurement protocols. (4) Standardized, practical and rapid methods for assessing biodiversity and ecosystem functions should be promoted to increase comparability among forest BEF experiments. We demonstrate that currently available methods provide us with a sophisticated toolbox to improve a synergistic understanding of forest multifunctionality. However, these methods require further adjustment to the specific requirements of structurally complex and long-lived forest ecosystems. By applying methods connecting relevant scales, trophic levels, and above- and belowground ecosystem compartments, knowledge gain from large tree diversity experiments can be optimized.
