RESUMEN

Na odontologia a decisão do tratamento é exclusiva dos cirurgiões dentistas e suas percepções, incluindo filosofia de tratamento, fazendo com que a prática de novos conceitos, tratamentos ou técnicas dependam não apenas de sua lógica ou eficácia biológica. Sendo assim, este estudo teve como objetivo avaliar os parâmetros envolvidos na tomada de decisão de cirurgiões dentistas clínicos e especialistas para a realização do tratamento endodôntico em sessão única ou múltiplas sessões. Para tanto, este estudo contou com uma coleta de dados através de um questionário online, aplicado cirurgiões dentistas clínicos gerais e especialistas em endodontia. As respostas foram tabuladas e analisadas por meio de estatística descritiva. Os resultados revelaram que a maioria dos endodontistas e dos clínicos gerais prefere realizar tratamento endodôntico em sessão única, devido ao menor desperdício de material, além do melhor domínio da anatomia e tratamento em um único momento. O motivo mais comum para os endodontistas e clínicos gerais escolherem o tratamento com múltiplas visitas é para dentes com prognóstico duvidoso e os casos em que o profissional aguarda a remissão dos sintomas antes da obturação. Em conclusão, a maioria dos endodontistas e dos clínicos gerais preferiu realizar tratamento endodôntico em sessão única.


In dentistry, treatment decisions are made exclusively by dental surgeons and their perceptions, including treatment philosophy, which means that the practice of new concepts, treatments or techniques depends not only on their logic or biological efficacy. Therefore, the aim of this study was to evaluate the parameters involved in clinical and specialist dental surgeons' decision to carry out endodontic treatment in single or multiple sessions. To this end, data was collected using an online questionnaire administered to general dental surgeons and endodontic specialists. The answers were tabulated and analyzed using descriptive statistics. The results revealed that the majority of endodontists and general practitioners prefer to carry out endodontic treatment in a single session, due to less wastage of material, as well as better mastery of the anatomy and treatment at a single time. The most common reason for endodontists and general practitioners to choose treatment with multiple visits is for teeth with a doubtful prognosis and cases in which the professional is waiting for symptoms to remit before filling. In conclusion, the majority of endodontists and general practitioners preferred to carry out endodontic treatment in a single session.

RESUMEN

Currently, the treatment of bone defects in arthroplasty is a challenge in clinical practice. Nonetheless, commercially available orthopaedic scaffolds have shown limited therapeutic effects for large bone defects, especially for massiveand irregular defects. Additively manufactured porous tantalum, in particular, has emerged as a promising material for such scaffolds and is widely used in orthopaedics for its exceptional biocompatibility, osteoinduction, and mechanical properties. Porous tantalum has also exhibited unique advantages in personalised rapid manufacturing, which allows for the creation of customised scaffolds with complex geometric shapes for clinical applications at a low cost and high efficiency. However, studies on the effect of the pore structure of additively manufactured porous tantalum on bone regeneration have been rare. In this study, our group designed and fabricated a batch of precision porous tantalum scaffolds via laser powder bed fusion (LPBF) with pore sizes of 250 µm (Ta 250), 450 µm (Ta 450), 650 µm (Ta 650), and 850 µm (Ta 850). We then performed a series of in vitro experiments and observed that all four groups showed good biocompatibility. In particular, Ta 450 demonstrated the best osteogenic performance. Afterwards, our team used a rat bone defect model to determine the in vivo osteogenic effects. Based on micro-computed tomography and histology, we identified that Ta 450 exhibited the best bone ingrowth performance. Subsequently, sheep femur and hip defect models were used to further confirm the osteogenic effects of Ta 450 scaffolds. Finally, we verified the aforementioned in vitro and in vivo results via clinical application (seven patients waiting for revision total hip arthroplasty) of the Ta 450 scaffold. The clinical results confirmed that Ta 450 had satisfactory clinical outcomes up to the 12-month follow-up. In summary, our findings indicate that 450 µm is the suitable pore size for porous tantalum scaffolds. This study may provide a new therapeutic strategy for the treatment of massive, irreparable, and protracted bone defects in arthroplasty.

RESUMEN

Meniscus is vital for maintaining the anatomical and functional integrity of knee. Injuries to meniscus, commonly caused by trauma or degenerative processes, can result in knee joint dysfunction and secondary osteoarthritis, while current conservative and surgical interventions for meniscus injuries bear suboptimal outcomes. In the past decade, there has been a significant focus on advancing meniscus tissue engineering, encompassing isolated scaffold strategies, biological augmentation, physical stimulus, and meniscus organoids, to improve the prognosis of meniscus injuries. Despite noteworthy promising preclinical results, translational gaps and inconsistencies in the therapeutic efficiency between preclinical and clinical studies exist. This review comprehensively outlines the developments in meniscus tissue engineering over the past decade (Scheme 1). Reasons for the discordant results between preclinical and clinical trials, as well as potential strategies to expedite the translation of bench-to-bedside approaches are analyzed and discussed.

RESUMEN

La evaluación de la marcha en cinta caminadora puede resultar relevante para la toma de decisiones clínicas. No obstante, factores demográficos como la edad y el IMC pueden alterar la interpretación de los resultados. Nuestro objetivo fue obtener variables espacio- temporales, energéticas y costo de transporte durante la velocidad autoseleccionada en cinta caminadora para una muestra representativa de adultos uruguayos (n=28) y evaluar si diferentes rangos de edades e IMC pueden ser factores a tener en cuenta en pruebas clínicas donde se consideren dichas variables. Participaron 17 hombres y 11 mujeres (39,3 ± 14,8 años, 75,9 ± 12,5 kg, 1,74 ± 0,09 m, IMC 25,2 ± 4,06). Se realizó una reconstrucción 3D del movimiento en forma sincronizada con el consumo energético. Se obtuvieron valores de referencia y luego de agrupar los participantes según su IMC y rango de edad se compararon los datos mediante test de t (p≤0.05). Los resultados revelaron discrepancias significativas en las medidas espacio-temporales y energéticas de los adultos uruguayos al caminar en cinta con respecto a la literatura. La marcha difiere entre adultos jóvenes y de mediana edad en su velocidad autoseleccionada (p=0,03), longitud de zancada (p=0,01), trabajo mecánico externo (<0,001) y recuperación de energía mecánica (0,009), destacando la importancia de considerar la edad en evaluaciones clínicas. El IMC no influyó significativamente en estas variables. Estos hallazgos subrayan la necesidad de ajustar las interpretaciones de las pruebas clínicas de la marcha sobre cinta caminadora en adultos uruguayos de mediana edad (45 a 65 años).


Treadmill gait assessment can be relevant for clinical decision-making. However, demographic factors such as age and BMI may alter result interpretation. Our aim was to obtain spatiotemporal, energetic, and cost of transport variables during self-selected treadmill walking speed for a representative sample of Uruguayan adults (n=28) and to assess if different age ranges and BMI could be factors to consider in clinical tests involving these variables. Seventeen men and eleven women participated (39.3 ± 14.8 years, 75.9 ± 12.5 kg, 1.74 ± 0.09 m, BMI 25.2 ± 4.06). A synchronized 3D motion reconstruction was performed with energy consumption. Reference values were obtained and data were compared using t-tests (p≤0.05), after grouping participants by BMI and age range. Results revealed significant discrepancies in spatiotemporal and energetic measures of Uruguayan adults walking on the treadmill, compared to the literature. Gait differed between young and middle-aged adults in their self-selected speed (p=0.03), stride length (p=0.01), external mechanical work (p<0.001), and mechanical energy recovery (0.009), emphasizing the importance of considering age in clinical evaluations. BMI did not significantly influence these variables. These findings underscore the need to adjust interpretations of treadmill gait clinical tests in middle-aged Uruguayan adults (45 to 65 years).


A avaliação da marcha na esteira pode ser relevante para a tomada de decisões clínicas. No entanto, fatores demográficos como idade e IMC podem alterar a interpretação dos resultados. Nosso objetivo foi obter variáveis espaço-temporais, energéticas e custo de transporte durante a velocidade de caminhada autoselecionada na esteira para uma amostra representativa de adultos uruguaios (n = 28) e avaliar se diferentes faixas etárias e IMC podem ser fatores a serem considerados em testes clínicos que envolvam essas variáveis. Dezessete homens e onze mulheres participaram (39,3 ± 14,8 anos, 75,9 ± 12,5 kg, 1,74 ± 0,09 m, IMC 25,2 ± 4,06). Foi realizada uma reconstrução tridimensional do movimento sincronizada com o consumo de energia. Foram obtidos valores de referência e os dados foram comparados usando testes t (p≤0,05), após agrupar os participantes por IMC e faixa etária. Os resultados revelaram discrepâncias significativas nas medidas espaço-temporais e energéticas dos adultos uruguaios ao caminhar na esteira, em comparação com a literatura. A marcha diferiu entre adultos jovens e de meia-idade em sua velocidade autoselecionada (p=0,03), comprimento da passada (p=0,01), trabalho mecânico externo (<0,001) e recuperação de energia mecânica (0,009), destacando a importância de considerar a idade em avaliações clínicas. O IMC não influenciou significativamente essas variáveis. Esses achados destacam a necessidade de ajustar as interpretações dos testes clínicos de marcha na esteira em adultos uruguaios de meia- idade (45 a 65 anos).

RESUMEN

O manejo clínico em Odontopediatria é individual, podendo variar nas diversas culturas mundiais. O objetivo desta revisão de literatura é reunir as principais diretrizes de diferentes países ao redor do mundo, incluindo o Brasil, visando identificar como em cada lugar o uso das técnicas de comportamento são aplicadas e sua eficiência. Inicialmente, foram selecionados os principais guias nacionais e internacionais, sendo eles retirados da Associação Internacional de Odontopediatria (IAPD) e Associação Americana de Odontopediatria (AAPD), além de artigos de diferentes países e continentes, como Argentina, Brasil, Europa e Ásia, também foram analisados se o protocolo dos principais guias estão condizentes com os protocolos do Departamento de Clínica Infantil da Faculdade de Odontologia de Ribeirão Preto - USP. Os resultados obtidos nos guias para manejo clínico odontológico brasileiro, americano, internacional e os artigos estudados recomendam inicialmente utilizar técnicas menos invasivas, com o intuito proporcionar um atendimento tranquilo e sem criar traumas para a criança, uma vez que muito do comportamento não cooperativo vem de experiências anteriores traumáticas. Entretanto, técnicas avançadas podem ser utilizadas para casos mais desafiadores. Concluímos com o estudo dos guias e artigos, que o cirurgião dentista possui diversas técnicas a serem aplicadas para que o atendimento infantil seja atraumático e restabelecer saúde ao paciente.


Clinical management in Pediatric Dentistry is individual and varies across different cultures around the world. The objective of this literature review is to bring together the main guidelines from different countries around the world, including Brazil, aiming to identify how the use of behavioral techniques are applied and their efficiency in each place. Initially, the main national and international guides were selected, taken from the International Association of Pediatric Dentistry (IAPD) and the American Association of Pediatric Dentistry (AAPD), as well as articles from different countries and continents, such as Argentina, Brazil, Europe and Asia, as well as It was analyzed whether the protocols of the main guides are consistent with the protocols of the Children's Clinic Department of the Faculty of Dentistry of Ribeirão Preto - USP. The results obtained in the guides for Brazilian, American and international dental clinical management and the articles studied recommend initially using less invasive techniques, with the aim of providing calm care and without creating trauma for the child, since much of the uncooperative behavior comes from previous traumatic experiences. However, advanced techniques can be used for more challenging cases. We conclude from studying the guides and articles that the dental surgeon has several techniques to be applied so that child care is atraumatic and restores health to the patient.

RESUMEN

This first-of-its-kind study explored the essential competencies healthcare chaplaincy hiring managers (HCHMs) sought for entry-level healthcare chaplains (HCCs). We conducted qualitative interviews with 16 HCHMs and using reflexive thematic analysis (RTA), developed nine key themes: interpersonal skills, teamwork, knowledge of family and group dynamics, understanding of the healthcare system, professionalism, proficiency in spiritual assessment, effective communication, commitment to lifelong learning, and knowledge of various religious and spiritual beliefs, extending beyond one's own faith tradition. These themes reflected HCCs roles as healthcare professionals who contribute to patient care, interdisciplinary collaboration, and spiritual leadership responsibilities. The study underscored the need for chaplaincy education to integrate healthcare-specific coursework, interprofessional training, cultural and religious humility, and deeper knowledge of diverse belief systems. Developing and incorporating curriculum standards based on these themes could enhance the readiness of HCCs to deliver comprehensive care and meet the dynamic demands of diverse patient populations within today's healthcare landscape.

RESUMEN

INTRODUCTION: We evaluated the treatment outcomes and failure patterns in cT3N0 breast cancer patients classified for rigorous pretreatment evaluation and treated with neoadjuvant chemotherapy (NAC) and curative surgery. METHODS: We reviewed the records of 87 cT3N0 breast cancer patients who received NAC and curative surgery between 2000 and 2015. The clinical high-risk group was defined as having two or more risk factors: age < 40, histologic grade 3, lymphovascular invasion, hormone receptor negativity, and Ki-67 labeling index >20%. RESULTS: Of the patients, 84 (96.6%) and 79 (90.8%) were initially evaluated using magnetic resonance imaging and positron emission tomography/computed tomography. Most patients received anthracycline based NAC regimen (n = 69, 79.3%) and modified radical mastectomy (n = 61, 70.1%). During a 91.5-month median follow-up, ten patients experienced distant metastasis (DM) only, two had isolated local recurrence, one had local recurrence and DM, and another had local recurrence, regional recurrence, and DM. The 5-year rates of locoregional recurrence, DM, any recurrence (AR), and overall survival (OS) were 1.2%, 11.6%, 11.6%, and 90.8%, respectively. The risk group was an independent prognostic factor of recurrence, and the high-risk group had worse rates of DM (19.2% vs. 0%, P = 0.009), AR (19.2% vs. 0%, P = 0.016) and OS (82.8% vs. 100%, P = 0.001). CONCLUSION: Patients with cT3N0 breast cancer classified for rigorous pretreatment evaluation and treated with NAC and radical surgery had favourable oncological outcomes. A clinical risk group based on clinical and immunohistochemical risk factors was an excellent predictor of survival and recurrence.

RESUMEN

BACKGROUND: In response to the high patient admission rates during the COVID-19 pandemic, provisional intensive care units (ICUs) were set up, equipped with temporary monitoring and alarm systems. We sought to find out whether the provisional ICU setting led to a higher alarm burden and more staff with alarm fatigue. OBJECTIVE: We aimed to compare alarm situations between provisional COVID-19 ICUs and non-COVID-19 ICUs during the second COVID-19 wave in Berlin, Germany. The study focused on measuring alarms per bed per day, identifying medical devices with higher alarm frequencies in COVID-19 settings, evaluating the median duration of alarms in both types of ICUs, and assessing the level of alarm fatigue experienced by health care staff. METHODS: Our approach involved a comparative analysis of alarm data from 2 provisional COVID-19 ICUs and 2 standard non-COVID-19 ICUs. Through interviews with medical experts, we formulated hypotheses about potential differences in alarm load, alarm duration, alarm types, and staff alarm fatigue between the 2 ICU types. We analyzed alarm log data from the patient monitoring systems of all 4 ICUs to inferentially assess the differences. In addition, we assessed staff alarm fatigue with a questionnaire, aiming to comprehensively understand the impact of the alarm situation on health care personnel. RESULTS: COVID-19 ICUs had significantly more alarms per bed per day than non-COVID-19 ICUs (P<.001), and the majority of the staff lacked experience with the alarm system. The overall median alarm duration was similar in both ICU types. We found no COVID-19-specific alarm patterns. The alarm fatigue questionnaire results suggest that staff in both types of ICUs experienced alarm fatigue. However, physicians and nurses who were working in COVID-19 ICUs reported a significantly higher level of alarm fatigue (P=.04). CONCLUSIONS: Staff in COVID-19 ICUs were exposed to a higher alarm load, and the majority lacked experience with alarm management and the alarm system. We recommend training and educating ICU staff in alarm management, emphasizing the importance of alarm management training as part of the preparations for future pandemics. However, the limitations of our study design and the specific pandemic conditions warrant further studies to confirm these findings and to explore effective alarm management strategies in different ICU settings.

RESUMEN

Normobaric hyperoxia (NBO) is a potentially promising stroke treatment strategy that could protect the ischemic penumbra and could be administered as an adjunct before vascular recanalization. However, the efficacy and safety of NBO have not been confirmed by randomized controlled trials. The study aims to assess the efficacy and safety of NBO for ischemic stroke due to large artery occlusion (LVO) of acute anterior circulation among patients who had endovascular treatment (EVT) and were randomized within 6 h from symptom onset. Based on the data of the modified Rankin Scale (mRS) score at 90 days from the normobaric hyperoxia combined with EVT for acute ischemic stroke (OPENS: NCT03620370) trial, 284 patients will be included to achieve a 90% power by using Wilcoxon-Mann-Whitney test and the proportional odds model to calculate the sample size. The study is a prospective, multicenter, blinded, randomized controlled trial. The NBO group is administered with mask oxygen therapy of 10 L/min, while the sham NBO group is with that of 1 L/min. The primary outcome is the mRS score at 90 days. Secondary endpoints include cerebral infarct volume at 24-48 h, functional independence (mRS ≤2) at 90 days, and improvement in neurological function at 24 h. Safety outcomes include 90-day mortality, oxygen-related adverse events, and serious adverse events. This study will indicate whether NBO combined with EVT is superior to EVT alone for acute ischemic stroke caused by LVO in subjects randomized within 6 h from symptom onset and will provide some evidence for NBO intervention as an adjunct to thrombectomy for acute stroke.

RESUMEN

BACKGROUND: Clinical ethics consultants support mental health professionals in identifying and analyzing moral problems in clinical practice. OBJECTIVE: Presentation of key ethical concepts and normative theories that are relevant for clinical ethics consultation in mental healthcare. MATERIAL AND METHODS: Conceptual and ethical analyses. RESULTS: After distinguishing between morality, ethics and law, moral problems are differentiated from other types of problems encountered in clinical practice. Subsequently, key ethical concepts and the concept of moral distress are clarified. In relation to the normative framework a distinction is made between philosophical ethical theories and medical ethical theories, such as principlism and the ethics of care. Finally, justification tests for ethical decision-making in situations of danger to self or others based on the harm principle and soft paternalism are proposed. CONCLUSION: Knowledge of key ethical concepts and normative theories is important for the identification and analysis of moral problems in mental healthcare and should be given greater weight in the training of clinical ethics consultants.

RESUMEN

The present real-world analysis aimed to evaluate and describe the use of gamma-hydroxybutyric acid (GHB) for alcohol withdrawal syndrome (AWS) in hospitalized patients with diagnosis of liver cirrhosis. An 11-year observational retrospective study on patients affected by liver cirrhosis and alcohol use disorder (AUD) was performed using data from the Medical Toxicology Unit of Careggi University Hospital in Florence (Italy). A multivariate logistic regression was performed to estimate the probability of having a CIWA-Ar Max 3-4 during hospitalization, an AWS length > 36 h, a hospitalization > 9 days, and the probability of developing drowsiness. A total of 166 AUD patients were included, of these 77 received GHB (70.13% within the first day of hospitalization) and 89 were treated without GHB. The majority were ≥ 40 years of age (87.35%) and males (80.12%). GHB patients were more likely to have a CIWA-Ar Max 3-4 during hospitalization (OR 3.76 [CI 95% 1.02-13.85]), and a longer hospitalization (OR 3.08 [95% CI 1.23-7.71]). Early GHB administration decreased the probability of CIWA-Ar Max worsening (OR 0.06 [95% CI 0.01-0.49]). GHB dose ≥ 100 mg/kg was not associated with the occurrence of drowsiness. Patients exposed to other sedative agents were more likely to experience drowsiness (OR 7.22 [95% CI 1.46-35.61]). The present real-world analysis underlines that GHB could be a valuable and safe option for the management of AWS in AUD patients affected by liver cirrhosis, also when administered early and even at higher than recommended dosages.

RESUMEN

Classically, a single renal artery supplies, and a single renal vein drains each kidney. The morphology and variations in the renal vascular structures are of great importance when performing any type of renal surgery. The present case describes a rare combination of renal vasculature variation in a formalin-fixed, Chinese male cadaver. In this case, the left kidney is drained by a main renal vein (MRV) and an inferior renal vein (IRV), the latter might be the remnant of the left dorsal renal vein during the embryonic period. Two sets of renal arteries are present in this case, possibly due to persistent mesonephric arteries during embryonic development. Describing such anatomical variations is not only of academic interest but also important to help radiologists with the correct interpretation of image examinations and for surgeons to be prepared in advance.

RESUMEN

BACKGROUND: Tryptase, a mast cell protease, has been identified as a potential therapeutic target in managing patients with refractory asthma. We assessed the efficacy, safety, pharmacokinetics, and pharmacodynamics of MTPS9579A, an anti-tryptase antibody, in a phase 2a randomized trial for patients with uncontrolled asthma and a phase 1c trial to understand activity within the lower respiratory tract. METHODS: Phase 2a patients (n = 134) received 1800 mg MTPS9579A or placebo intravenously every 4 weeks for 48 weeks. The primary endpoint was time to the first composite exacerbation event. Phase 1c patients (n = 27) received one intravenous dose of 300 or 1800 mg MTPS9579A or placebo. Both trials measured MTPS9579A concentrations and effects on tryptase in serum and nasal lining fluid; phase 1c also analyzed bronchial lining fluid. RESULTS: MTPS9579A did not meet the primary endpoint (hazard ratio = 0.90; 95% CI: 0.55-1.47; p = 0.6835); exacerbation rates in the placebo group were low. Serum and nasal MTPS9579A pharmacokinetics and tryptase levels were consistent with data from healthy volunteers. However, in phase 1c patients, compared to nasal levels, MTPS9579A bronchial concentrations were 6.8-fold lower, and bronchial active and total tryptase levels were higher (119-fold and 30-fold, respectively). Pharmacokinetic/pharmacodynamic modeling predicted intravenous doses of 3800 mg every 4 weeks would be necessary to achieve 95% active tryptase inhibition from baseline. CONCLUSIONS: The MTPS9579A dose tested in the phase 2a study was insufficient to inhibit tryptase in bronchial lining fluid, likely contributing to the observed lack of efficacy.

RESUMEN

INTRODUCTION: Accurate and rapid triage can reduce undertriage and overtriage, which may improve emergency department flow. This study aimed to identify the effects of a prospective study applying artificial intelligence-based triage in the clinical field. DESIGN: Systematic review of prospective studies. METHODS: CINAHL, Cochrane, Embase, PubMed, ProQuest, KISS, and RISS were searched from March 9 to April 18, 2023. All the data were screened independently by three researchers. The review included prospective studies that measured outcomes related to AI-based triage. Three researchers extracted data and independently assessed the study's quality using the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) protocol. RESULTS: Of 1633 studies, seven met the inclusion criteria for this review. Most studies applied machine learning to triage, and only one was based on fuzzy logic. All studies, except one, utilized a five-level triage classification system. Regarding model performance, the feed-forward neural network achieved a precision of 33% in the level 1 classification, whereas the fuzzy clip model achieved a specificity and sensitivity of 99%. The accuracy of the model's triage prediction ranged from 80.5% to 99.1%. Other outcomes included time reduction, overtriage and undertriage checks, mistriage factors, and patient care and prognosis outcomes. CONCLUSION: Triage nurses in the emergency department can use artificial intelligence as a supportive means for triage. Ultimately, we hope to be a resource that can reduce undertriage and positively affect patient health.

RESUMEN

Proper and timely characterization of the safety profile of a pharmaceutical product under development is imperative for assessing the overall benefit-risk relationship of the product and for making key development decisions. For ongoing clinical development, a comprehensive and robust safety monitoring and safety signal detection program which is based upon quantitative statistical reasoning is critical. Methods presented here can be applied to safety signal detection and periodic safety monitoring. Various statistical properties, distributions, and models, all utilizing a Bayesian framework are considered and further examined in order to identify robust methods applicable to a broad set of scenarios and situations. Methods developed for incidence counts (including those with under-dispersed distributions) with variable time-at-risk and with underlying constant or non-constant hazard rates, are proposed and compared to traditional methods designed to assess adverse event incidence rates or binomial incidence proportions (which assume an underlying constant hazard rate and subsequent Poisson distribution for modeling event counts).

RESUMEN

BACKGROUND: Human adenovirus (HAdV) is an important pathogen causing acute respiratory infection (ARI) in children. Many countries, including China, have experienced sporadic or outbreaks related to HAdV-4, and death cases were reported. However, there is little research on HAdV-4 and the epidemic situation of HAdV-4 in China is little known. This study was designed to comprehend the prevalence and genetic characteristics of HAdV-4 in ARI children in China. METHODS: Respiratory tract samples from ARI children hospitalized in six hospitals of Northern and Southern China from 2017 to 2020 were collected for HAdV detection and typing. Clinical information was collected from HAdV-4 positive patients for clinical characteristics and epidemiological analysis. The main capsid proteins and the whole genome sequences were amplified and sequenced for bioinformatics analysis. RESULTS: There were 2847 ARI children enrolled, and 156 (5.48%) HAdV positive samples were detected. Eleven HAdV-4 positive samples were identified, accounting for 0.39% of the total samples and 7.05% of the HAdV positive samples. The main manifestations were fever and cough. Two children had conjunctivitis. Two children were diagnosed with severe pneumonia and developed respiratory failure. One of them developed hemophagocytic syndrome and checked in pediatric intensive care unit (PICU). This child had ventricular septal defect. All the children recovered. The isolated strains of HAdV-4 obtained in this study and the reference strains from China located in the same phylogenetic branch (HAdV-4a), while the prototype strain and vaccine strains formed another branch (HAdV-4p). Upon comparison with the prototype strain, there were a few amino acid mutations existing in three major capsid proteins. According to recombination analysis, no new recombination was found. CONCLUSIONS: The detection rate of HAdV-4 in children hospitalized with ARI was 0.39% in the total samples and 7.05% of all HAdV positive samples. HAdV-4 isolates obtained in this study and other reference strains from China belonged to the HAdV-4a subtype. Our data provided reference for the monitoring, prevention and control of HAdV-4, as well as the research and development of vaccines and drugs.

RESUMEN

PURPOSE: In the context of clinical research, there is an increasing need for new study designs that help to incorporate already available data. With the help of historical controls, the existing information can be utilized to support the new study design, but of course, inclusion also carries the risk of bias in the study results. METHODS: To combine historical and randomized controls we investigate the Fill-it-up-design, which in the first step checks the comparability of the historical and randomized controls performing an equivalence pre-test. If equivalence is confirmed, the historical control data will be included in the new RCT. If equivalence cannot be confirmed, the historical controls will not be considered at all and the randomization of the original study will be extended. We are investigating the performance of this study design in terms of type I error rate and power. RESULTS: We demonstrate how many patients need to be recruited in each of the two steps in the Fill-it-up-design and show that the family wise error rate of the design is kept at 5 % . The maximum sample size of the Fill-it-up-design is larger than that of the single-stage design without historical controls and increases as the heterogeneity between the historical controls and the concurrent controls increases. CONCLUSION: The two-stage Fill-it-up-design represents a frequentist method for including historical control data for various study designs. As the maximum sample size of the design is larger, a robust prior belief is essential for its use. The design should therefore be seen as a way out in exceptional situations where a hybrid design is considered necessary.

RESUMEN

Innovative technology-based solutions in mental healthcare promise significant improvements in care quality and clinical outcomes. However, their successful implementation is profoundly influenced by the levels of trust patients hold toward their treatment providers, organizations, and the technology itself. This paper delves into the complexities of building and assessing patient trust within the intensive mental health care context, focusing on inpatient settings. We explore the multifaceted nature of trust, including interpersonal, institutional, and technological trust. We highlight the crucial role of therapeutic trust, which comprises both interpersonal trust between patients and providers, and institutional trust in treatment organizations. The manuscript identifies potential key barriers to trust, from sociocultural background to a patient's psychopathology. Furthermore, it examines the concept of technological trust, emphasizing the influence of digital literacy, socio-economic status, and user experience on patients' acceptance of digital health innovations. By emphasizing the importance of assessing and addressing the state of trust among patients, the overarching goal is to leverage digital innovations to enhance mental healthcare outcomes within intensive mental health settings.
