In the city of Buenos Aires, Argentine Republic, not only the census but also the records in private veterinarians allow you to estimate the animals with responsible holder, but to guarantee the success of health plans for the ethical control of urban fauna is necessary to estimate on a consistent basis. The presence of stray pets (dogs and cats) was registered in all the communes of the Autonomous City of Buenos Aires, using a systematic sampling, selecting a set of streets in each commune in the form of Greek guard. The results showed, based on 208 sightings, a total of dogs in street condition of 91,73 ± 33,12 animals every 1000 blocks. [ABSTRACT FROM AUTHOR]

In the present paper the possible association between body temperature, glycemia and lacticaemia with the surgical act of sterilization of male and female canines is studied. These variables were chosen since they are known to be modified in the face of stressful events. It is expect d to observed changes in metabolic substrates used by the patient during surgery. The variables of interest were studied in three times (pre and intra-surgical) in male and female canines. Significant decreases in lactate and rectal temperature and a significant increase in blood glucose were detected. [ABSTRACT FROM AUTHOR]

Background: Closure of rural obstetric (OB) units has led to maternal care deserts, causing mothers to travel long distances for maternity care. Emergency departments (EDs) in hospitals where OB units have closed require regular training for personnel to maintain OB skills, as do rural Level-1 OB units with low volumes of maternity cases. We used a federal grant to develop an OB mobile simulation program to bring simulation-based training to rural providers. Our goal was to improve OB skills and standardize care through the framework of the Alliance for Innovation in Maternal Health (AIM) Patient Safety Bundles., Methods: We conducted needs assessments and built a mobile simulation unit. We defined 2 groups of learners: those in Level-1 OB units and those in EDs without OB units. For Level-1 OB units, we created a train-the-trainer curriculum, to create a statewide cohort of simulation experts to implement simulations in their facilities between our visits. We gifted each Level-1 unit an OB task trainer, implemented virtual train-the-trainer simulation and task trainer workshops, and conducted post-workshop assessments. We then traveled to each Level-1 unit and helped the cohort implement in situ simulations for their staff using facility-specific resources. We conducted assessments for the cohort and the hospital staff after the simulations. For EDs, we delivered virtual didactics to improve basic OB knowledge, then traveled to ED units, implemented in situ simulations, and conducted post-simulation assessments. We chose a postpartum hemorrhage (PPH) scenario for our first round of simulations., Results: After train-the-trainer simulation workshops, 98% of participants surveyed agreed that workshop goals and objectives were achieved. After the task trainer workshop, 95% surveyed agreed that their knowledge of using the simulator had improved. After implementing in situ simulations in Level-1 OB units, 98.8% of the train-the-trainer cohort found that their ability to implement simulations had improved. The hospital staff participating in the simulations identified a 30% increase in ability to manage PPH. For the ED staff, postdidactic evaluations identified that 95.4% of participants reported moderate improvement in basic OB knowledge and after participation in the simulations >95% reported better skills as an ED team member when caring for pregnant patients., Conclusions: These results demonstrate improved skills of hospital staff in simulated PPH in Level-1 OB units and simulated OB emergencies in EDs that no longer have OB units. Further studies are warranted to assess improvement in maternal outcomes., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 International Anesthesia Research Society.)

Paper is one of the most promising materials for food packaging and wrapping due to its low environmental impact, but surface treatments are often needed to improve its performance, e.g., the resistance to fats and oils. In this context, this research is focused on the formulation of a new paper bio-coating. Paper was coated with liquids containing poly(hexano-6-lactone) (PCL), glycerol and variable percentages of starch (5-10% w / w PCL dry weight), agar-agar (0-1.5% w / w PCL dry weight), and polyethylene glycol (PEG) (5% or 15% w / w PCL dry weight) to improve coating uniformity and diffusion. A design of experiments approach was implemented to find statistically reliable results in terms of the best coating formulation. Coated paper was characterized through mechanical and physical properties. Results showed that agar content (1.5% w / w PCL dry weight) has a beneficial effect on increasing the resistance to oil. Furthermore, the best coating composition has been calculated, and it is 10% w / w PCL dry weight of starch, 1.5% w / w PCL dry weight of agar, and 15% w / w PCL dry weight of PEG.

Introduction: Globally, non-communicable diseases (NCDs) are the leading causes of morbidity and mortality with an estimated 41 million deaths (74% of all global deaths) annually. Despite the WHO's Global Action Plan for the Prevention and Control of NCDs since 2013, progress on implementation of the guidelines has been slow. Although research has shown success of some NCD prevention and treatment interventions, there is a dearth of research on NCD care delivery approaches, cost-effectiveness and larger implementation research, especially in low/middle-income countries (LMICs). The objective of this scoping review is to identify the existing variation in how, why and by whom implementation of NCD guidelines is measured as part of implementation research or non-research programme improvement., Methods and Analysis: Using the methods established by Arksey and O'Malley, the search strategy was developed in consultation with a research librarian together with stakeholder feedback from content experts. We will apply the search to multiple electronic databases and grey literature sources. Two reviewers will independently screen title and abstract for inclusion followed by a full-text screening and all included records will be abstracted using a standardised tool that will be piloted with a sample of articles before application to all records. We will conduct a narrative synthesis of abstracted data and simple quantitative descriptive statistics., Dissemination: The results will enable stakeholders in LMICs to leverage existing tools and resources for implementation and ongoing evaluation of NCD guidelines, to improve education and capacity building, and ultimately NCD care across the lifespan., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Since the discovery of DNA as the genetic material, scientists have been investigating how the information contained in this biological polymer is transmitted from generation to generation. X-ray crystallography, and more recently, cryo-electron microscopy techniques have been instrumental in providing essential information about the structure, functions and interactions of the DNA and the protein machinery (replisome) responsible for its replication. In this chapter, we highlight several works that describe the structure and structure-function relationships of the core components of the prokaryotic and eukaryotic replisomes. We also discuss the most recent studies on the structural organization of full replisomes., (Copyright © 2023. Published by Elsevier Inc.)

Acrylamide in biscuits represents a major concern. This research work was aimed at modifying the current formulation of biscuits to reduce the acrylamide content while maintaining the chemical, physical, and sensory characteristics of the original product. A strategy based on the FoodDrinkEurope Acrylamide Toolbox was adopted. The content of the leavening agent ammonium bicarbonate, the baking temperature program, and the time duration of steam released during the baking process were the three factors evaluated through a factorial design of experiment. The partial replacement of ammonium bicarbonate (from 9.0 g to 1.5 g per 500 g of flour) with sodium bicarbonate (from 4.5 g to 12.48 g), lowering of the temperature in the central phase of the baking process (from 170 °C to 150 °C), and the release of steam for 3 min resulted in an 87.2% reduction in acrylamide concentration compared to biscuits of reference. CIELab color indices and a w were the parameters that showed the most significant correlation with acrylamide concentration in biscuits and could, therefore, become markers to predict the acrylamide content along production lines for an instant evaluation.

Objectives: To assess pediatrician adherence to the 2017 American Academy of Pediatrics' clinical practice guideline for high blood pressure (BP)., Study Design: Pediatric primary care practices (n = 59) participating in a quality improvement collaborative submitted data for patients with high BP measured between November 2018 and January 2019. Baseline data included patient demographics, BP, body mass index (BMI), and actions taken. Logistic regression was used to test associations between patient BP level and BMI with provider adherence to guidelines (BP measurement, counseling, follow-up, evaluation)., Results: A total of 2677 patient charts were entered for analysis. Only 2% of patients had all BP measurement steps completed correctly, with fewer undergoing 3-limb and ambulatory BP measurement. Overall, 46% of patients received appropriate weight, nutrition, and lifestyle counseling. Follow-up for high BP was recommended or scheduled in 10% of encounters, and scheduled at the appropriate interval in 5%. For patients presenting with their third high BP measurement, 10% had an appropriate diagnosis documented, 2% had appropriate screening laboratory tests conducted, and none had a renal ultrasound performed. BMI was independently associated with increased odds of counseling, but higher BP was associated with lower odds of counseling. Higher BP was independently associated with an increased likelihood of documentation of hypertension., Conclusions: In this multisite study, adherence to the 2017 American Academy of Pediatrics' guideline for high BP was low. Given the long-term health implications of high BP in childhood, it is important to improve primary care provider recognition and management., Trial Registration: ClinicalTrials.gov: NCT03783650., (Copyright © 2021 Elsevier Inc.

Germinal centers (GC) are dynamic, short-lived anatomical structures generated within lymphoid follicles during immune responses to protein-containing antigens. There, follicular dendritic cells, antigen-specific B cells, and follicular T helper cells engage with each other in an antigen dependent way, setting into play a mini-evolutionary ecosystem that ultimately lead to antibody affinity maturation, with the resulting GC reaction following a rise-and-fall dynamics. The complexity of the cell-to-cell interaction processes makes very difficult to mechanistically understand the GC dynamics. Different mathematical or computational models have been or can be developed to help clarify the mechanisms driving and regulating the GC dynamics. However, the very important question of which are the dominant model parameters is not frequently studied for most of those models. Here we describe in detail one method to perform such a parameter analysis-known as parameter sensitivity analysis-which can be applied to many models of the GC dynamics., (© 2022.

Objective: To assess the perspectives of neonatologists, neonatal nurses, and parents on research-related education and communication practices in the neonatal intensive care unit (NICU)., Study Design: Questionnaire circulated through interest groups and administered using the internet., Results: 323 respondents responded to the survey. 52 were neonatologists, 188 were neonatal nurses, and 83 were parents of NICU graduates. Analysis was descriptive. Differences were noted between stakeholder groups with respect to whether current medications meet the needs of sick neonates, research as central to the mission of the NICU, availability of appropriate education/training for all members of the research team, and adequacy of information provided to parents before, during, and after a research study is completed., Conclusion: Engagement of nurses and parents at all stages of NICU research is currently suboptimal; relevant good practices, including education, should be shared among neonatal units., (© 2021.

Background: Correctional facilities increasingly offer medications for opioid use disorder (OUD), including buprenorphine. Nevertheless, retention in treatment post-incarceration is suboptimal and overdose mortality remains high. Our objectives were to understand how incarcerated patients viewed buprenorphine treatment and identify modifiable factors that influenced treatment continuation post-release., Methods: We conducted semi-structured interviews with 22 men receiving buprenorphine treatment in an urban jail. Interviews were audio recorded, professionally transcribed, and analyzed using a grounded-theory approach. Team members constructed preliminary case memos from transcripts, and then interactively discussed themes within respective memos. We established participant 'typologies' by consensus., Results: Distinct typologies emerged based on participants' post-release treatment goals: (1) those who viewed buprenorphine treatment as a cure for OUD; (2) those who thought buprenorphine would help manage opioid-related problems; and (3) those who did not desire OUD treatment. Participants also described common social structural barriers to treatment continuation and community re-integration. Participants reported that post-release housing instability, unemployment, and negative interactions with parole contributed to opioid use relapse and re-incarceration., Conclusion: Participants had different goals for post-release buprenorphine treatment continuation, but their prior experiences suggested that social structural issues would complicate these plans. Incarceration can intensify marginalization, which when combined with heightened legal supervision, reinforced cycles of release, relapse, and re-incarceration. Participants valued buprenorphine treatment, but other structural and policy changes will be necessary to reduce incarceration-related inequities in opioid overdose mortality., (Copyright © 2021 Elsevier B.V.

Introduction: Imaging tests are essential for diagnosis in the emergency context and convey clinical information that is essential to assess the appropriateness of the tests and improve their interpretation. Therefore, we aimed to analyze the imaging tests requested by the Emergency Department in a district hospital., Material and Methods: We retrospectively analyzed computed tomography and ultrasound scans requested by the Emergency Department at the Centro Hospitalar Universitário do Algarve and considered the following variables: requested test, clinical information provided (complete/incomplete), appropriateness of the test (appropriate/inappropriate), outcome (presence/absence of relevant findings) and findings related to the clinical information (yes/no). Pearson's chi-squared and odds ratio association tests were used to evaluate the statistical association between the variables., Results: Out of 1427 requests, only 219 (15.3%) were considered to have complete clinical information. Nonetheless, 1075 (75.3%) requests were considered appropriate. Relevant findings were present in about one-third (n = 453; 31.7%) and most of these findings were related to the clinical context (n = 410; 90.5%). There was a significant association between test appropriateness and the presence of relevant findings in the test (p < 0.001). The odds ratio of having a relevant finding was 5.0 times higher in the tests considered appropriate when compared with those classified as inappropriate (CI = 3.4 - 7.3; p < 0.001)., Discussion: The fact that appropriate tests potentiate the probability of having a relevant finding emphasizes the importance of defining guidelines so that only the adequate tests are performed., Conclusion: Creating guidelines should improve the appropriateness of imaging tests requested in the Emergency Department, yielding their result, with the consequent rationalization of the available resources.

Germinal centers (GCs) are transient anatomical microenvironments where antibody affinity maturation and memory B cells generation takes place. In the past, models of Germinal Center (GC) dynamics have focused on understanding antibody affinity maturation rather than on the main mechanism(s) driving their rise-and-fall dynamics. Here, based on a population dynamics model core, we compare three mechanisms potentially responsible for this GC biphasic behavior dependent on follicular dendritic cell (FDC) maturation, follicular T helper (Tfh) cell maturation, and antigen depletion. Analyzing the kinetics of B and T cells, as well as its parameter sensitivities, we found that only the FDC-maturation-based model could describe realistic GC dynamics, whereas the simple Tfh-maturation and antigen-depletion mechanisms, as implemented here, could not. We also found that in all models the processes directly related to Tfh cell kinetics have the highest impact on GC dynamics. This suggests the existence of some still unknown mechanism(s) tuning GC dynamics by affecting Tfh cell response to proliferation-inducing stimuli.
