Psychological Effects of Sport Injury on NCAA Division I Student Athlete: A Qualitative Case Study

Negative emotional states are common for injured athletes, yet a 2016 survey suggested that only 38.3% of NCAA institutions had a full or part-time mental health professional (Kroshus, 2016). In considering the lack of support for mental health conditions in NCAA institutions, and the mental and psychological issues that come with injury, there is a gap in the psychological treatment of injured student athlete. To date, the extant literature suggests that sport medicine professionals (SMPs) play a critical role in the psychology of injury recovery, yet lack formal training in psychological interventions (Clement et al., 2013). Moreover, research examining athlete and SMPs experiences of the psychological aspects of injury rehabilitation is largely limited to retrospective accounts (e.g., Clement et al., 2015; Tatsumi & Takenouchi, 2014). The purpose of the current study was to prospectively examine the psychological challenges of injury rehabilitation in an NCAA athlete. A qualitative case study grounded in narrative methodology, and an interpretive epistemology, was conducted (Smith, 2009). Research interviews were conducted with an injured athlete, the athlete’s SMP, and a member of the athlete’s social support team at baseline (i.e., post-injury and prior to the start of rehabilitation) and during the rehabilitation process before the sport-specific phase. Additionally, the athlete kept a journal to document the psychological and emotional struggles that took place during the rehabilitation process. Data analysis was iterative through each phase of the study and followed Polkinghorne’s (1995) seven stages of narrative analysis. Results suggest that issues with identity are central to the injury-rehabilitation-return to play process. Notably, data suggest an ongoing struggle between the loss of identity in the present, the fear of identity loss in the future, and a desire to maintain a positive outlook on current circumstances, and ongoing tensions between cognitive appraisals and emotional reactions. The work of SMPs and sport psychology professionals working with injured athletes seems to be highly linked to the cognitive appraisals and behavioral responses and emotional responses respectively. While cognitive appraisal and behavioral responses seem to be congruent, cognitive appraisals and emotional responses appear to lack this dynamic. Suggested in this case, psychological interventions (specifically support groups) seem to be helpful in working through emotional stresses that come up throughout the rehabilitation process

Management and outcomes of pregnant ICU patients with severe COVID-19 pneumonia in Qatar: A retrospective cohort study

Introduction: Pregnant women are considered a high-risk group for COVID-19 due to their increased vulnerability to viral infections. The impact of COVID-19 on pregnant women is not well understood, and there is a need for data on managing severe COVID-19 in pregnant patients. This retrospective descriptive cohort study described the characteristics, hospital stay, interventions, and outcomes of pregnant patients admitted to the intensive care units (ICUs) with severe COVID-19 pneumonia in Qatar. Methods: Data were collected from medical records and chart reviews of pregnant women admitted to Hamad Medical Corporation (HMC) with COVID-19 pneumonia from March 01, 2020, to July 31, 2021. The inclusion criteria encompassed pregnant women with a positive polymerase chain reaction (PCR) antigen test or radiological changes at admission, requiring respiratory support, and hospitalized for more than 24 hours. Results: A total of 43 pregnant women were included in this study. Most patients were admitted during the first wave of the pandemic, with a median gestational age of 212 days [interquartile range 178–242 days] at presentation. The most common respiratory support methods were high-flow nasal cannula, non-invasive positive pressure ventilation, and invasive positive pressure ventilation. Convalescent plasma therapy was administered to 58% of patients, and tocilizumab was used in 28%. Renal replacement therapy was required by 4.6% of patients and 7% required extracorporeal membrane oxygenation. Conclusion: This study provides valuable insights into the impact of COVID-19 on pregnant patient

Identification of slit3 as a locus affecting nicotine preference in zebrafish and human smoking behaviour

To facilitate smoking genetics research we determined whether a screen of mutagenized zebrafish for nicotine preference could predict loci affecting smoking behaviour. From 30 screened F-3 sibling groups, where each was derived from an individual ethyl-nitrosurea mutagenized F-0 fish, two showed increased or decreased nicotine preference. Out of 25 inactivating mutations carried by the F-3 fish, one in the slit3 gene segregated with increased nicotine preference in heterozygous individuals. Focussed SNP analysis of the human SLIT3 locus in cohorts from UK (n=863) and Finland (n=1715) identified two variants associated with cigarette consumption and likelihood of cessation. Characterisation of slit3 mutant larvae and adult fish revealed decreased sensitivity to the dopaminergic and serotonergic antagonist amisulpride, known to affect startle reflex that is correlated with addiction in humans, and increased htr1aa mRNA expression in mutant larvae. No effect on neuronal pathfinding was detected. These findings reveal a role for SLIT3 in development of pathways affecting responses to nicotine in zebrafish and smoking in humans.Peer reviewe

Adult zebrafish as a model organism for behavioural genetics

Recent research has demonstrated the suitability of adult zebrafish to model some aspects of complex behaviour. Studies of reward behaviour, learning and memory, aggression, anxiety and sleep strongly suggest that conserved regulatory processes underlie behaviour in zebrafish and mammals. The isolation and molecular analysis of zebrafish behavioural mutants is now starting, allowing the identification of novel behavioural control genes. As a result of this, studies of adult zebrafish are now helping to uncover the genetic pathways and neural circuits that control vertebrate behaviour

Molecular psychiatry of zebrafish

Due to their well-characterized neural development and high genetic homology to mammals, zebrafish (Danio rerio) have emerged as a powerful model organism in the field of biological psychiatry. Here, we discuss the molecular psychiatry of zebrafish, and its implications for translational neuroscience research and modeling central nervous system (CNS) disorders. In particular, we outline recent genetic and technological developments allowing for in vivo examinations, high-throughput screening and whole-brain analyses in larval and adult zebrafish. We also summarize the application of these molecular techniques to the understanding of neuropsychiatric disease, outlining the potential of zebrafish for modeling complex brain disorders, including attention-deficit/hyperactivity disorder (ADHD), aggression, post-traumatic stress and substance abuse. Critically evaluating the advantages and limitations of larval and adult fish tests, we suggest that zebrafish models become a rapidly emerging new field in modern molecular psychiatry research

Dysfonctions somatiques du rachis cervical et traitement multi-attache : une étude transversale sur 145 sujets

Objectifs : Le but de cette étude transversale effectuée en aveugle est d’évaluer l’influence d’un appareil orthodontique fixe sur le rachis cervical. Matériels et méthodes : Le nombre et la gravité des dysfonctions somatiques (altération dans la fonction d’un élément constituant le système somatique ou DS) du rachis cervical ont été étudiés chez des patients classés en trois groupes : sujets sans traitement orthodontique (groupe 1), sujets portant un appareil orthodontique fixe (groupe 2) et sujets en contention après la dépose de l’appareil orthodontique fixe (groupe 3) et comparés grâce au test du khi2. Résultats : Un total de 145 patients âgés de 6 à 17 ans ont été inclus. Il y avait plus de DS dans le groupe 2 (p = 0,006) que dans le groupe 1. Il n’y avait pas de différence entre le groupe 1 et 3 (p = 0,2), entre le groupe 2 et 3 (p = 0,4) et entre les trois groupes (p = 0,6) concernant la sévérité des DS. Conclusion : Les troubles cervicaux ne devraient pas être imputés à long terme au traitement multi-attache puisqu’une fois le traitement orthodontique actif fini, les DS ne sont pas significativement augmentées par rapport au groupe contrôle. Ces résultats incitent à effectuer une étude pour évaluer le bénéfice d’un suivi ostéopathique des patients à risque après la pose de l’appareil multi-attache
