Overnight In-House Critical Care Resource Intensivist Improves General Surgery Resident Education.

24/7 critical care staffing has become more commonplace, and their impact on resident training must be carefully considered. At our institution, the Critical Care Resource Intensivist (CCRI) model was implemented to provide in-house dedicated faculty responsible solely for the provision of critical care overnight. An anonymous survey was distributed to all general surgery residents to evaluate CCRI's impact on education and autonomy. Descriptive statistics were completed for quantitative data. Qualitative analysis of free text responses was completed to identify consensus themes. Responses from 26 residents demonstrated they associated CCRI with improved resident education, supervision, and patient care, without limiting autonomy. Qualitative analysis yielded 7 themes, reflecting improvements in patient care and safety, progression of care, operations and procedures, improved education, availability, and independence, but noted potential for conflict. Our findings show 24/7 dedicated intensivist staffing can enhance general surgery resident education without limiting autonomy.

Dynamic Molecular Markers of Otosclerosis in the Human Cochlea.

OBJECTIVE: To investigate the role and distribution of various molecular markers using immunohistochemistry and immunofluorescence to further elucidate and understand the pathogenesis of otosclerosis. METHODS: Archival celloidin formalin-fixed 20-micron thick histologic sections from 7 patients diagnosed with otosclerosis were studied and compared to controls. Sections in the mid-modiolar region were immunoreacted with rabbit polyclonal antibodies against nidogen-1, ß2-laminin, collagen-IX, BSP, and monoclonal antibodies against TGF ß-1 and ubiquitin. Digital images were acquired using a high-resolution light and laser confocal microscope. RESULTS: Nidogen-1, BSP, and collagen-IX were expressed in the otospongiotic regions, and to lesser extent, in the otosclerotic regions, the latter previously believed to be inactive. ß2-laminin and ubiquitin were uniformly expressed in both otospongiotic and otosclerotic regions. There was a basal level of expression of all of these markers in the normal hearing and sensorineural hearing loss specimens utilized as control. TGF ß -1, however, though present in the otosclerosis bones, was absent in the normal hearing and sensorineural hearing loss controls. CONCLUSIONS: Our results propose that the activity and function of TGF-1 may play a key role in the development and pathogenesis of otosclerosis. Further studies utilizing a higher number of temporal bone specimens will be helpful for future analysis and to help decipher its role as a potential target in therapeutic interventions.

Social norms and goal-setting interventions to promote responsible gambling in low-to-moderate online gamblers: protocol for a four-arm randomised controlled feasibility study.

INTRODUCTION: Gambling is increasingly recognised as an important public health issue. Problem gambling is associated with highly negative impacts on physical, psychological and social well-being, not only for those who gamble but also for those around them. There has been a rapid expansion of internet gambling and attributes such as continuous play and instant rewards, and enhanced privacy may lead to a greater likelihood of gambling-related harms. In this randomised controlled feasibility study, we are testing (1) the acceptability and feasibility of three online responsible gambling interventions targeting people with low-to-moderate risk of online problem gambling and (2) the feasibility of a future full-scale randomised controlled trial (RCT) to test their effectiveness and cost-effectiveness. METHODS AND ANALYSIS: Four-arm randomised controlled feasibility study with qualitative substudy. One-hundred and forty UK residents with low-to-moderate risk of online gambling recruited via gambling operators and social media will be randomised (1:1:1:1) to either (1) goal setting, (2) descriptive norms messages (challenge perceptions of peer behaviours), (3) injunctive norms messages (challenge perceptions of peer attitudes) and (4) control (delayed intervention). Interventions will be delivered over 6 weeks and individually tailored. Outcomes, administered online, will be measured at baseline, 7 weeks, and 3 and 6 months post randomisation (including gambling risk behaviours and cognitions, anxiety and depression, quality of life, health use and productivity). Analyses will be descriptive, focusing on feasibility and acceptability of the interventions and study procedures. Telephone/online interviews, with a subsample of approximately 30 participants, will elicit experiences of participating in the study. Prespecified progression criteria will guide decisions around whether to progress to a definitive RCT. ETHICS AND DISSEMINATION: Ethical approval obtained from Bournemouth University Research Ethics Committee (reference number 33247). Participants will be given a participant information sheet plus a 'Key Facts' summary and will provide informed online consent. Findings will be published in peer-reviewed journals and presented at conferences and public engagement events. TRIAL REGISTRATION NUMBER: ISRCTN37874344.

Prioritizing Flexibility, Human Connection, and Representation: Findings from the Qualitative Process Evaluation of the Special Projects of National Significance Black Men Who Have Sex with Men Initiative.

Previous research has identified significant unmet need for behavioral health care services for Black men who have sex with men (Black MSM); this challenge has been linked to poorer overall health and well-being. Health Resources and Services Administration (HRSA) funded a Special Projects of National Significance (SPNS) Initiative, Implementation of Evidence-Informed Behavioral Health Models to Improve HIV Health Outcomes for Black Men who have Sex with Men, with a goal to integrate behavioral health and clinical care services using four different evidence-informed models of care, ultimately improving HIV health outcomes. NORC at the University of Chicago conducted a multisite evaluation to assess the success of this Initiative, including a qualitative process evaluation that examined adaptations, services, integration activities, recruitment methods, and fidelity. The process evaluation described methods and processes used by demonstration sites to achieve their goals. This included challenges or barriers to implementation and the associated adaptations, notably due to the COVID-19 Public Health Emergency. Our study found key themes that indicated successful implementation were flexible service delivery, human connection, and client representation. We recommend future replicators apply these lessons learned in diverse health care and community settings that serve Black MSM. Additional information about the interventions can be found on TargetHIV.

Evaluating Evidence-Informed Behavioral Health Models to Improve HIV Health Outcomes: Quantitative Findings from the Ryan White HIV/AIDS Program Special Projects of National Significance Black Men Who Have Sex with Men Initiative.

The Black Men who have Sex with Men (MSM) Initiative was implemented at eight sites to engage and retain Black MSM in HIV medical care and supportive services (SS) by addressing their behavioral health (BH) care needs. Using a pre-post design and generalized logistic mixed-effects models adjusting for patient-level random effects, site, baseline age, and baseline mental health status, we evaluated whether participants experienced increased postintervention attainment of (1) Awareness of HIV medical care, BH care, and SS; (2) Screening, referral, linkage, receipt, and engagement in HIV care, BH care, and SS; and (3) Retention, antiretroviral therapy prescription, and suppressed viral load. Among 758 evaluated participants, the proportion of participants who were aware of, screened for, screened positive for, and referred to BH and SS, retention in care (72% to 79%), and viral load suppression (68% to 75%) increased between baseline and postintervention. Among participants who screened positive and received BH services were statistically more likely to be linked to [OR, 1.34 (95% CI: 1.08-1.66)] and retained in [OR, 1.36 (95% CI: 1.00-1.83)] care. Among those who screened positive and received SS were statistically more likely to be retained in care [OR, 1.54 (95% CI: 1.07-2.22)]. Measures of linkage to care declined significantly during the study period, perhaps because of COVID-19 that delayed in-person care. This study suggests that interventions designed to increase utilization of BH services and SS can be effective at improving retention in care and viral load suppression among Black MSM, at least among those currently using HIV services.

Implementation of Evidence-Informed Behavioral Health Models to Improve HIV Health Outcomes for Black Men Who Have Sex With Men (Black MSM Initiative): Protocol for Program Evaluation.

BACKGROUND: The HIV epidemic in the United States disproportionately affects Black communities. Nearly half of Black men who have sex with men (MSM) will be diagnosed with HIV in their lifetime. There is a significant unmet need for behavioral health care services among Black MSM, and untreated behavioral health needs make it less likely the person is retained in HIV care. OBJECTIVE: This paper offers a description of the Implementation of Evidence-Informed Behavioral Health Models to Improve HIV Health Outcomes for Black Men who have Sex with Men (Black MSM) Initiative, a program to integrate clinical care and behavioral health/supportive services for Black MSM with HIV. The Black MSM Initiative is funded through the Health Resources & Services Administration HIV/AIDS Bureau Ryan White HIV/AIDS Program (RWHAP) Part F Special Projects of National Significance. METHODS: The components of the Black MSM Initiative include providing technical assistance to 8 Initiative demonstration sites; conducting a comprehensive and culturally responsive, mixed method, multisite evaluation; and disseminating evaluation findings and lessons learned to the RWHAP community. RESULTS: As of December 31, 2020, demonstration sites enrolled 809 clients in the multisite evaluation. The research team will continue evaluation data collection through December 2021 for analysis and dissemination starting in 2022. The Black MSM Initiative fully supports the US Department of Health and Human Services' Ending the HIV Epidemic in the United States Initiative. CONCLUSIONS: In order to succeed, providers and programs will need to engage populations traditionally considered "hard to reach," like many people receiving RWHAP services. Findings and lessons learned from the Black MSM Initiative will expand the tool kit of solutions to support and retain Black MSM in HIV care, furthering the goals of the Ending the HIV Epidemic Initiative and the RWHAP.

Validation and comparison of fall screening tools for predicting future falls among older adults.

BACKGROUND: Falls are the leading cause of injuries among older adults in the United States (US). Falls are preventable and clinicians are advised to screen for fall risk yearly. There are many falls screening tools and not all have been validated for their ability to predict future falls. METHODS: We enrolled 1905 community-dwelling older adults into a 13-month study using a probability-based representative panel of the US population recruited from NORC at the University of Chicago's National Frame. Respondents completed a baseline survey, 11 monthly fall calendars, and a final survey. The baseline survey included six falls screening tools (the Stay Independent, Three Key Questions (3KQ), a modified American Geriatric/British Geriatric tool, the short Falls Efficacy-1[FES-I]) and two single screening questions ("I have fallen in the past year" and "How many times did you fall in the past 12 months?"). The baseline and final survey collected demographic and health information, including falls. Sensitivity, specificity, positive and negative likelihood ratios, and corresponding 95% confidence intervals were calculated in SAS using weighted proportions. RESULTS: There were 1563 respondents who completed the final survey (completion rate 82%). Sensitivity estimates ranged from 22.5% for the short FES-I to 68.7% for the 3KQ. Specificity estimates ranged from 57.9% for the 3KQ to 89.4% for the short FES-I. CONCLUSIONS: Falls screening tools have varying sensitivity and specificity for predicting the occurrence of a fall in the following 12 months.

What's in the box? Exploring UK players' experiences of loot boxes in games; the conceptualisation and parallels with gambling.

Loot boxes are a popular mechanic within many video games, but it remains unclear if some forms of loot boxes can be seen of as gambling. However, the perspectives of players are often neglected, such as whether they see them as 'fair' game elements and how closely they feel this aligns with gambling. In this paper, we synthesise a conceptualisation for loot boxes through players' actual experience and explore if there are any parallels with gambling. Twenty-one participants who played video games took part in the research through either an interview or online survey. Thematic analysis suggested that six themes were core to exploring loot boxes: Random Chance Effects, Attitudes Towards Content, Implementation, Parallels with Gambling, Game Design, and The Player. The results suggested both indirect and direct parallels with gambling from the players experiences. Implications of game design and classifying loot boxes as gambling are discussed in relation to game design and risk factors of gambling and purchasing behaviour.

Histopathologic Analysis of Temporal Bones With Otosclerosis Following Cochlear Implantation.

OBJECTIVE: Analyze changes in osteoneogenesis and fibrosis following cochlear implant (CI) surgery in patients with otosclerosis and compare differences based on insertion technique. BACKGROUND: When advanced otosclerotic disease extends to the otic capsule, severe and profound sensorineural hearing loss necessitates consideration of a cochlear implant. Histopathological analysis of the human temporal bone after implantation in the patient with otosclerosis may reveal important variables that predict CI success. METHODS: Histopathological evaluation of archival human temporal bones from subjects with a history of CI for cochlear otosclerosis. A total of 17 human temporal bones (HTB) were analyzed, 13 implanted, and 4 contralateral non-implanted controls. RESULTS: Histopathological studies revealed extensive osteoneogenesis and fibrosis which was more prominent at the cochleostomy insertion site in the basal turn of the cochlea often obliterating the scala tympani in the basal turn, and in some cases extending to the scala media and scala vestibuli. Cochlear hydrops was nearly universal in these cases. This contrasted with the round window insertion, which exhibited minimal osteoneogenesis within the cochlear duct. In addition, in the contralateral, unimplanted control ears, there was otosclerosis at the stapes footplate, fissula ante fenestrum but no osteoneogenesis within the cochlear duct. CONCLUSION: Cochleostomy approach to CI insertion in otosclerosis patients is associated with significant fibrosis, osteoneogenesis, and cochlear hydrops. A round window insertion technique can be utilized to help minimize these histopathologic findings whenever feasible.

Cisplatin ototoxicity histopathology.

This study investigates the histopathological changes of the cochlea and vestibular end organs of a patient who received cisplatin for Hodgkin's lymphoma. He experienced acute high-frequency sensorineural hearing loss and tinnitus after receiving treatment. Using histopathological analysis of his temporal bones after he unfortunately succumbed to his disease, we found that the ototoxic effect of cisplatin is primarily within the cochlea, with significant damage located at the organ of Corti at the base-hook region, consistent with findings in animal models. The effects of cisplatin were minimal when reviewing the vestibular end organs.

Novel molecular biomarkers and diagnosis of acute appendicitis in children.

Reliable and efficient diagnosis of pediatric appendicitis is essential for the establishment of a clinical management plan and improvement of patient outcomes. Current strategies used to diagnose a child presenting with a suspected appendicitis include laboratory studies, clinical scores and diagnostic imaging. Although these modalities work in conjunction with each other, one optimal diagnostic strategy has yet to be agreed upon. The recent introduction of precision medicine techniques such as genomics, transcriptomics, proteomics and metabolomics has increased both the diagnostic sensitivity and specificity of appendicitis. Using these novel strategies, the integration of precision medicine into clinical practice via point-of-care technologies is a plausible future. These technologies would assist in the screening, diagnosis and prognosis of pediatric appendicitis.

Enlarged Vestibular Aqueduct: Hearing Progression and Cochlear Implant Candidacy in Pediatric Patients.

HYPOTHESIS/OBJECTIVE: Investigate the rate of hearing loss progression and incidence of cochlear implant candidacy in children with enlarged vestibular aqueduct (EVA). BACKGROUND: EVA is the most common congenital malformation of the inner ear, is responsible for a large percentage of children with hearing loss, and is associated with hearing loss progression. Rates and degree of progression of hearing loss to cochlear implantation candidacy have not been well described. METHODS: Review of children with EVA who presented to a single academic medical center. Audiometric data were reviewed to determine subjects who met criteria for cochlear implantation (≥75 dB pure-tone average) at presentation. For those not meeting criteria, serial audiometric data were reviewed for progression to candidacy. RESULTS: A total of 257 ears met inclusion criteria. One hundred ninety-two (74.7%) met cochlear implant candidacy criteria by age 12, yet only 117 ears (60.9%) actually received implants before turning 13. One hundred fifty-three ears (59.5%) met implant candidacy criteria at presentation. Nearly 50% of those not initially meeting implantation criteria had a ≥15 dB shift in pure-tone average by age 12, with 37.5% of this subgroup meeting implant candidacy criteria before their teen years at an average age of 7.10 years. CONCLUSION: The majority of children with EVA reach cochlear implant candidacy before reaching adulthood, yet implantation rates for candidate ears remain at 60% and delay in implantation persist. Parents of children with EVA should be counseled on the likelihood of progression and closely monitored for cochlear implant candidacy.

Cerebrospinal Fluid Leak Following Translabyrinthine Vestibular Schwannoma Surgery-Is Mesh Cranioplasty Necessary for Prevention?

OBJECTIVE: Evaluate the incidence of cerebrospinal fluid leak following vestibular schwannoma surgery for mesh cranioplasty closure versus periosteal closure in the translabyrinthine approach. Determine nonsurgical variables associated with higher rates of cerebrospinal fluid leak following vestibular schwannoma surgery. STUDY DESIGN: Retrospective chart review. SETTING: Tertiary academic referral center. PATIENTS: One hundred thirty-two patients with adequate documentation who underwent sporadic vestibular schwannoma resection via a translabyrinthine approach between 2000 and 2019. INTERVENTION: Translabyrinthine excision of vestibular schwannoma with mesh cranioplasty closure or watertight periosteal closure. MAIN OUTCOME MEASURES: Primary outcome measures included the incidence of postoperative cerebrospinal fluid leak, total length of hospital stay (including the initial hospital stay as well as hospital days during any readmission within 30 days), and total operative time. RESULTS: Our overall cerebrospinal fluid leak rate was 9.1% with a leak rate of 12.8% in our translabyrinthine titanium mesh closure group and 0% in our translabyrinthine periosteal closure. There was no statistically significant effect of age, body mass index, or size of tumor on the incidence of cerebrospinal fluid leak. There was also no statistically significantly difference between the two groups on length of operative time or number of days spent in the intensive care unit. CONCLUSION: Mesh cranioplasty is not a prerequisite for achieving a low cerebrospinal fluid leak rate following translabyrinthine approach for vestibular schwannoma resection. In our series, a significantly lower cerebrospinal fluid leak rate was demonstrated with the periosteal closure.

Visual task complexity and eye movement patterns influence measures of human neurovascular coupling.

Human neurovascular coupling research conventionally aims to selectively activate the posterior circulation using a visual task. Different research groups use divergent visual tasks ranging in complexity and eye movement patterns with potential confounding effects. To understand the role of task complexity and eye movement patterns in neurovascular coupling, we performed a series of experiments with visual tasks ranging in complexity, eye speed, and eye movement amplitude. Greater task complexity significantly reduced selectivity for the posterior circulation. Greater task amplitude (i.e. larger eye movements) increased selectivity. These findings are important when interpreting and designing neurovascular coupling investigations.

Is It Still Double Edged? Not for University Students' Development of Moral Reasoning and Video Game Play.

Previous research with video game play and moral development with adolescents, found both positive and negative relationships. This study aimed to extend this research to explore moral development and video game play with university students. One hundred and thirty-five undergraduate students (M = 20.29, SD = 2.70) took part in an online survey. The results suggested higher moral reasoning for participants who described themselves as gamers and those which do not play, compared those who play but do not identify as gamers. It was suggested that males had higher moral scores and more mature reasoning than females. The results of a regression analysis suggested that there were no significant predictors for moral development from either game play or the demographic variables. The findings suggest that moral development could be less influenced by sex, age, and video game play factors such as video game content and amount of game play, than was previously thought for this age group.

Assessing Cochlear Implant Insertion Angle From an Intraoperative X-ray Using a Rotating 3D Helical Scala Tympani Model.

BACKGROUND: Angular insertion depth (AID) of the electrode array provides valuable information regarding intracochlear positioning, which can be used to predict outcomes and optimize performance. While computed tomography (CT) offers high-resolution imaging, there is a need to develop technology to accurately determine AID from intraoperative x-rays acquired at unknown angles. METHODS: An algorithm was developed using a three-dimensional model of the scala tympani to estimate AID from an x-ray acquired at an unknown angle. The model is manipulated over the x-ray until the projection angle is inferred and the location of the round window and individual electrode contacts are identified. Validation of the algorithm involved 1) assessing accuracy with deviation from cochlear view by comparing AID determined with simulated x-rays to those determined with CT in a temporal bone model, and 2) assessing reproducibility in the clinical setting, by comparing intra- and inter-rater reliability with intraoperative x-ray in cochlear implant (CI) recipients, which were subsequently compared to AID determined with postoperative CT. RESULTS: Estimates of AID from x-rays were generally within 10 degrees of CT regardless of deviation from cochlear view. Excluding two outliers with poor imaging quality, the intraclass correlation coefficients for intra- and inter-rater reliability were excellent (0.991 and 0.980, respectively). CONCLUSION: With intraoperative x-rays of sufficient quality, the helical scala tympani model can be used to accurately and reliably determine AID without the need to specify a preferred image angle. The application can therefore be used in most CI recipients when a postoperative CT is not available.

Streamlining care in cystic fibrosis: survey of otolaryngologist, pulmonologist, and patient experiences.

BACKGROUND: Care coordination for cystic fibrosis (CF) is essential. The objectives of this study were to: (1) compare otolaryngologists' and pulmonlogists' understanding of long-term chronic rhinosinusitis (CRS) management; and (2) query patient perceptions of otolaryngologic care and CRS. METHODS: A cross-sectional survey was administered by the Cystic Fibrosis Foundation in 2018 to patients with CF or their caregivers, otolaryngologists, and pulmonologists. Statistical analysis was performed comparing specialists. Descriptive statistics were computed for patient/caregiver-reported data. RESULTS: Respondents included 126 otolaryngologists, 115 pulmonologists, and 186 patients with CF or their caregivers. Pulmonologists had greater experience caring for CF patients compared with otolaryngologists (66.7% vs 43.2% with 13+ years of experience, respectively), but more otolaryngologists cared for both adult and pediatric CF patients (39.2% vs 10.4%, respectively). Significantly more otolaryngologists advocated for establishing otolaryngologic care at time of CF diagnosis (64.8%) compared with pulmonologists (14.4%, p < 0.001), of whom 60.4% recommended otolaryngologist referral when sinonasal symptoms affect quality of life. More otolaryngologists perceived sinus surgery as beneficial for pulmonary function (74.5% vs 57.7%, p = 0.009); 60.8% of patients first sought otolaryngologic care in infancy or childhood (<13 years). Median number of sinus surgeries was 3 (interquartile range, 2-5). The most common perceived benefits of surgery according to patients/caregivers included improved breathing (31.2%) and improved sinonasal symptoms (23.7%). Top patients/caregiver otolaryngologic priorities included symptom/infection control (49.0%) and care coordination (15.0%). CONCLUSION: Our results highlight variable patient/caregiver experiences, and suggest that otolaryngologist and pulmonologist perceptions of CF otolaryngologic care also differ in some respects requiring improved interspecialty coordination/education.

An Innovative Approach to Airway Foreign Body Management in an Extremely Premature Neonate.

This case report is a retrospective review of a challenging though ultimately successful removal of an airway foreign body in a 2-day-old premature female born at 23 weeks and 4 days gestation. A segment of a 5-F surfactant catheter was cut and accidentally dislodged in the distal airway within the lumen of the patient's endotracheal tube. Ultimately, visualization was obtained using a 1.6-mm KARL STORZ sialoendoscope, and retrieval was performed using sialoendoscopy forceps passed via the working channel of the sialoendoscope while maintaining ventilation. This case represents an innovative approach to complex airway foreign body management utilizing sialoendoscopy instruments. Laryngoscope, 130:1236-1238, 2020.

It's Double Edged: The Positive and Negative Relationships Between the Development of Moral Reasoning and Video Game Play Among Adolescents.

Due to the concerns over the effects of video game play, this study investigated adolescents' moral development and their video game play. 166 adolescents aged 11-18 years (M = 13.08, SD = 1.91) attending an English school completed an online survey, which included a measure of moral development and questions regarding video game play. In contrast to previous research, male participants were found to have significantly (p = 0.02) higher moral reasoning scores than females. The results also suggested a transition in moral development, which takes place between the ages of 12-14. The results of moral development and video game played suggested both positive and negative relationships. Regression analysis suggested that there was a significant positive relationship between the more types of game genres played and higher moral scores. Although not significant, the results suggested a trend for the following variables; years playing video games, mature content, engagement, moral narrative, Grand Theft Auto, Call of Duty, and length of time playing video games which all had a negative relationship with moral scores. The implications of these results are discussed with regards to moral education and the variables involved in video game play, including the role of video game content.
