This study evaluated the impact of delivery of the Period of PURPLE Crying (PURPLE), in a group of first-time mothers. Frustration with crying is reported as a trigger for abusive head trauma (AHT).The primary objective was to determine whether there was a change in knowledge about crying and shaking after exposure to PURPLE. Factors associated with behavioral responses to crying were studied as was the utility of PURPLE. There was a significant increase in knowledge about infant crying (P = 0.001) after program delivery that was predicted by low baseline knowledge (P < 0.01). There was a non-significant negative change in shaking knowledge (P = 0.5), which may have been the consequence of high baseline knowledge of shaking. The PURPLE program was characterized as informative and useful by participants. Additional to evaluate the impact of program delivery on other caregivers and on the rates of AHT is recommended.

Background: Child maltreatment is a serious health concern in the United States (U.S.) affecting as many as one in four children throughout their lifetime (Finkelhor, Turner, Ormond, & Hamby, 2013). In 2013, a reported 678, 932 victims of child maltreatment were reported to Child Protective Services (CPS), and of those cases 1,520 were fatal (CDC, 2015a). Out of all the various types of child maltreatment, Shaken Baby Syndrome (SBS) is the leading cause of child abuse deaths in the U.S. (CDC, n.d.). While current research has focused on validating the effectiveness of educational interventions, very few studies have analyzed the efficacy of individualized, patient-centered action plans. Such data would be beneficial to assess the usefulness of action plans in preparing caregivers for coping with an inconsolable infant at home. Purpose: To enhance caregiver knowledge about SBS and to provide parents with the skills and resources necessary to cope effectively and efficiently at home when unable to console their infant. Methods: This study utilized a quasi-experimental pre-test/post-test design. Participants were recruited from the Franciscan Women’s Health Associates located at St. Joseph Medical Center in Tacoma, Washington and were members of the Centering prenatal groups. The entirety of the study was completed during these groups including the pre-test, intervention, action plan, and post-test. Data was analyzed through the utilization of descriptive statistics as well as a paired t test. Results: Overall, results revealed that participant (n=26) knowledge significantly improved after the educational intervention (p=0.000) with a mean score of 87.56% on the pre-test and a mean score of 95.38% on the post-test. In addition, a majority of participants (57.5%) found both the action plan and the education to be extremely useful. Discussion: The results of this study were consistent with current evidence indicating that education on SBS, the dangers of shaking, and healthy coping mechanisms significantly impacts caregiver knowledge. In addition, a majority of participants viewed the action plans favorably identifying that they would be beneficial if they felt frustrated. Future research is warranted to gather more information on the long-term outcomes of educational interventions as well as individualized action plans.

abstract: Traumatic injuries are the leading cause of death in children under 18, with head trauma being the leading cause of death in children below 5. A large but unknown number of traumatic injuries are non-accidental, i.e. inflicted. The lack of sensitivity and specificity required to diagnose Abusive Head Trauma (AHT) from radiological studies results in putting the children at risk of re-injury and death. Modern Deep Learning techniques can be utilized to detect Abusive Head Trauma using Computer Tomography (CT) scans. Training models using these techniques are only a part of building AI-driven Computer-Aided Diagnostic systems. There are challenges in deploying the models to make them highly available and scalable. The thesis models the domain of Abusive Head Trauma using Deep Learning techniques and builds an AI-driven System at scale using best Software Engineering Practices. It has been done in collaboration with Phoenix Children Hospital (PCH). The thesis breaks down AHT into sub-domains of Medical Knowledge, Data Collection, Data Pre-processing, Image Generation, Image Classification, Building APIs, Containers and Kubernetes. Data Collection and Pre-processing were done at PCH with the help of trauma researchers and radiologists. Experiments are run using Deep Learning models such as DCGAN (for Image Generation), Pretrained 2D and custom 3D CNN classifiers for the classification tasks. The trained models are exposed as APIs using the Flask web framework, contained using Docker and deployed on a Kubernetes cluster. The results are analyzed based on the accuracy of the models, the feasibility of their implementation as APIs and load testing the Kubernetes cluster. They suggest the need for Data Annotation at the Slice level for CT scans and an increase in the Data Collection process. Load Testing reveals the auto-scalability feature of the cluster to serve a high number of requests. / Dissertation/Thesis / Masters Thesis Software Engineering 2020

Parmi les manifestations de la maltraitance de l’enfant, problème de santé publique, le traumatisme crânien infligé de l’enfant est une des premières causes de mortalité par maltraitance. L’objectif de cette thèse était d’évaluer l’opportunité d’un dépistage de la maltraitance physique de l’enfant. Le premier obstacle mis en évidence était l’imprécision et le manque de standardisation de la définition de la maltraitance physique. Face à cet obstacle,nous nous sommes interrogés sur la perception qu’avaient les professionnels de santé et les parents des urgences pédiatriques du CHU de Bordeaux de la violence physique des parents vis-à-vis de leur enfant. Les professionnels étaient plus tolérants vis-à-vis de ces violences.Une même situation était évaluée différemment selon le professionnel. Nous avons illustré la variabilité de perception d’une même situation lorsque l’enfant ne présente pas encore de conséquences graves de maltraitance à travers un cas clinique de traumatisme crânien infligé,ainsi que les craintes d’une stigmatisation des parents directement en lien avec la difficulté à identifier précocement ces situations et les effets négatifs que peut avoir la prise en charge.Enfin, nous avons simulé par un modèle de Markov, en tenant compte des incertitudes identifiées, l’impact d’un programme de prévention primaire et d’un programme de dépistage du traumatisme crânien infligé. Ce modèle a permis de confirmer l’intérêt d’un programme de prévention primaire. Il a également montré l’importance de déterminer les effets possibles d’une stigmatisation à tort des parents dans le cadre du dépistage pour s’assurer qu’un tel programme ne serait pas néfaste. / Among child abuse, which is a major public health issue, Pediatric Abusive Head Trauma is one of the major causes of death in abused children. The aim of this thesis was to assess the opportunity of screening for physical child abuse. The first identified obstacle was the lack of knowledge about the beginning of physical child abuse, and the vagueness and lack ofstandardization of its definition. Therefore, we conducted a study to assess the perception of physical violence by parents toward their children, by parents and professionals in the emergency department of the university hospital of Bordeaux. The professionals were more tolerant than parents and the perception of a same situation could vary according to the professional. We have illustrated this variation with a clinical case of Pediatric Abusive Head Trauma, when the child had not already serious consequences of child abuse. Similarly, the difficulty of early identification of abused children was responsible for the fear of mother’sstigmatization. And we discussed the impact of management of the children and their mother.Finally, we evaluated the impact of a primary prevention program and screening program ofPediatric Abusive Head Trauma using a Markov model considering identified uncertainties.The simulation confirmed the potential benefits of primary prevention program documentedthe huge uncertainty regarding benefits associated with screening of Pediatric Abusive HeadTrauma. Future research should in particular focus on describing the effects of wrong lyidentifying parents as abusers.

Each paper describes a stage of the study, with the final goal of evaluating the effectiveness of different materials to increase parents knowledge on abusive head trauma. The first paper describes a review of national and international literature, which aimed to give a current overview of abusive head trauma (AHT). According to the review, AHT can be defined as injury to the skull and intracranial contents to a child due to a sudden unintentional impact and/or a violent shaking. It occurs mainly with babies and children under 1 year of age and can result in serious consequences for children's development, including death. Although there are specific signs for this type of abuse, it can be mistaken for common child illnesses or accidental head trauma. Thus, it is essential that health professionals are trained for the correct diagnosis. One of the main factors associated with its occurrence is the baby crying, which highlights the need for intervention with parents in order to teach them about child development and safe strategies to deal with the baby. The second paper aimed to investigate the knowledge of newborn parents about some characteristics associated with AHT, such as the pattern of the infant crying in the first months of life, strategies to deal with the crying baby and the consequences of shaking a baby. The results indicated a lack of knowledge about the severity of shaking a baby, as well as a possible Brazilian belief that babies should not be left crying alone. In this sense, there is a need for these issues to be addressed in AHT prevention efforts. The third paper aimed to investigate the belief of Brazilian parents about corporal punishment to infants, and its possible relation with abusive head trauma. As opposed to the international literature, participants of this study did not consider shaking as an appropriate strategy to discipline the baby, agreeing more with this strategy when it aimed to sooth the baby. Furthermore, the results indicated that the caregivers evaluation about the strategy s harm potential seems to influence its adoption in discipline and soothing contexts. Finally, the last paper describes the evaluation of the effectiveness of three different informational materials to increase knowledge of Brazilian parents about this type of abuse. The materials consisted of a video on abusive head trauma, a pamphlet individually read on the AHT, and a video on child safety, unrelated to AHT and used for comparison purposes. The results suggest that reading the pamphlet could be a useful strategy in prevention programs, since it increased participants' knowledge about the severity of shaking a baby, as well as the likelihood of using strategies to distance themselves from the baby when stressed by the crying. Although less significant, the results of the group who watched the video on the AHT also indicated an increase in knowledge about the average number of daily hours of baby crying. It is hoped that the results found in this dissertation will guide future AHT preventive efforts in Brazil. / A presente dissertação foi escrita no formato de um compêndio de quatro textos científicos. Cada artigo descreve uma etapa do estudo, que teve como objetivo avaliar a eficácia de diferentes materiais informativos para aumentar o conhecimento de pais de recém-nascidos sobre o trauma craniano violento pediátrico. O primeiro artigo descreve uma revisão da literatura nacional e internacional, que teve como objetivo traçar um panorama atual do trauma craniano violento (TCV). De acordo com a revisão, o TCV pode ser definido como a lesão ao crânio ou ao conteúdo intracraniano de uma criança devido a um impacto brusco intencional e/ou a uma sacudida violenta. Ocorre principalmente com bebês e crianças menores de 1 ano de idade e pode resultar em consequências graves ao desenvolvimento infantil, incluindo a morte. Apesar de haver sinais específicos para esta forma de maus-tratos, eles podem se confundir com doenças comuns em crianças ou traumas cranianos acidentais. Deste modo, torna-se imprescindível o preparo clínico dos profissionais de saúde para o diagnóstico correto. Um dos principais fatores associados à sua ocorrência é o choro do bebê, destacando a necessidade de intervenção com pais no sentido de ensiná-los sobre desenvolvimento infantil e estratégias seguras para lidar com o bebê. O segundo artigo visou investigar o conhecimento de pais de recém-nascidos sobre algumas características associadas a esta forma de maus-tratos, tais como o padrão do choro do bebê nos primeiros meses de vida, as estratégias para lidar com o choro e as consequências de sacudi-lo. Os resultados indicaram um desconhecimento dos participantes sobre a gravidade de se sacudir um bebê, bem como uma possível crença brasileira de que os bebês não devem ser deixados chorando sozinho. Neste sentido, destaca-se a necessidade dessas questões serem contempladas nas ações de prevenção do TCV. O terceiro artigo objetivou investigar a crença de pais brasileiros sobre a punição corporal em bebês e sua possível relação com o trauma craniano violento. Diferentemente do que aponta a literatura internacional, os participantes do presente estudo não consideraram o sacudir como uma estratégia adequada para disciplinar o bebê, obtendo maior concordância quando avaliada em seu potencial tranquilizador. Além disso, os resultados indicaram que a avaliação que os cuidadores fazem do potencial prejudicial de determinada estratégia parece influenciar sua adoção no cuidado com o bebê, tanto para acalmá-lo, quanto para discipliná-lo. Por fim, o último artigo descreve a avaliação da eficácia de três materiais informativos diferentes para o aumento do conhecimento de pais brasileiros sobre essa forma de maus-tratos. Os materiais consistiram em um vídeo sobre o trauma craniano violento, um panfleto sobre o TCV e um vídeo sobre segurança infantil, que não abordava o TCV e foi utilizado como comparação. Os resultados sugerem que o e leitura individual do panfleto pode ser uma estratégia útil em programas de prevenção, uma vez que a mesma aumentou o conhecimento dos participantes sobre a gravidade de sacudir um bebê, bem como a probabilidade de utilizarem estratégias de se afastar do bebê, quando estressados pelo choro. Apesar de menos expressivos, os resultados do grupo que assistiu ao vídeo sobre o TCV também indicaram um aumento no conhecimento sobre o número médio diário de horas de choro do bebê. Espera-se que os resultados encontrados na presente dissertação possam fornecer embasamento para futuras ações de prevenção dessa forma de maus-tratos.
