RESUMO
BACKGROUND: There have been case reports of renal dysfunction with lithium toxicity among severely ill COVID-19 patients. Lithium levels may be affected by comorbid conditions and the presence of infective disease states like the SARS-CoV-2 which clearly adds systemic health burden. This study aimed to review the effect SARS-CoV-2 has on serum Li levels and the possible mechanism underlying it. METHODS: Retrospective data from all clinical service encounters within the University of Michigan health system between September 2019 and September 2023 were reviewed. The study cohort included 98 patients with an average age of 45 years (62% female) who were diagnosed with any subtype of bipolar disorder, actively taking Li, and infected with SARS-CoV-2 during the study timeframe. RESULTS: There was no overarching effect of a SARS-CoV-2 infection on Li chemistry in the overall sample. Higher serum Li levels were not significantly associated with SARS-CoV-2 infection nor total comorbidity index. However, higher Li levels were observed in males while infected with SARS-CoV-2 when compared with no infection. eGFR remained unassociated with serum Li level. Receiving COVID vaccination was associated with lower serum Li levels (Coeff. = - 0.88, p = 0.048). CONCLUSIONS: Patients with a diagnosis of BD, treated with Li, and infected with SARS-CoV-2 were not likely to present with elevated Li levels unless they are male or unvaccinated. Elevated serum Li level was not associated with significant renal dysfunction in this cohort. The case reports of severe renal complications and Li toxicity may be among cases of greater overall clinical severity of COVID-19. These findings are reassuring that Li may be used in the context of a COVID-19 illness but emphasize the ongoing need for clinical vigilance.

RESUMO
OBJECTIVE: This study investigates the association of nightmares beyond general sleep disturbance on neurobehavioral symptoms in adults with mild traumatic brain injury (mTBI). DESIGN: Secondary analysis of a concussion cohort study. PARTICIPANTS: One hundred and eleven adults older than 20 years with mTBI were recruited from a specialized concussion treatment center. MAIN MEASURES: Behavioral Assessment Screening Tool, Pittsburgh Sleep Quality Index, and self-report of nightmare frequency in the past 2 weeks. RESULTS: Among adults with mTBI, nightmares accounted for the greatest amount of variability in negative affect (ß = .362, P < .001), anxiety (ß = .332, P < .001), and impulsivity (ß = .270, P < .001) after adjusting for age and sex. Overall sleep disturbance had the strongest association with depression (ß = .493, P < .001), fatigue (ß = .449, P < .001), self-reported executive dysfunction (ß = .376, P < .001), and overall burden from concussive symptoms (ß = .477, P < .001). CONCLUSIONS: Nightmares and sleep disturbance are differentially associated with variance in neurobehavioral symptoms. Nightmares were independently associated with neurobehavioral symptoms representing an excess of normal functioning (eg, anxiety, impulsivity), while general sleep disturbance was associated with neurobehavioral symptoms representing functioning below normal levels (eg, depression, fatigue, self-reported executive dysfunction). Clinical and research implications are discussed.

OBJECTIVE: To identify neurobehavioral symptom profiles among persons with chronic traumatic brain injury (TBI) using the Behavioral Assessment Screening Tool (BAST) and to consider participant characteristics that differ between profile groups. SETTING: Community. PARTICIPANTS: Participants (n = 615) were English-speaking adults (≥18) and had a self-reported history of at least one TBI of any severity. DESIGN: Secondary analysis of cross-sectional data. MAIN MEASURES: The BAST measures neurobehavioral symptoms in the domains of Negative Affect, Fatigue, Executive Dysfunction, Impulsivity, and Substance Misuse. RESULTS: Using latent profile analysis (LPA), we identified 3 different neurobehavioral profiles. Overall symptom frequency and differences in the pattern of symptom frequency across domains differentiated the profile groups. Average domain scores differed significantly across the profiles (P < .001) for all domains except Fatigue (P = .076). Those in profile 3 (High-Risk group) reported the most frequent symptoms across all domains (similar Negative Affect frequency as profile 1). Substance Misuse was especially high in this group. Compared to profile 2 (High Negative Affect group), participants in profile 1 (Moderate-Risk group) endorsed significantly more frequent (and more variable) symptoms across all BAST domains, particularly Impulsivity and Substance Misuse. Participants in profile 2 endorsed the least frequent symptoms across all domains. Demographic comparison showed that groups differed based on gender, age, and injury severity (mild vs moderate-severe), with profile 3 composed of the most men and the most persons in early adulthood, and profile 2 composed of the most women and those with mild TBI. CONCLUSIONS: We differentiated 3 neurobehavioral symptom profiles among persons with chronic TBI and determined differences in sociodemographic factors between the groups. Future research should focus on validating these profiles in another sample of individuals with chronic TBI. Characterizing persons according to multidimensional symptom profiles could allow for more tailored approaches to predict and prevent long-term negative outcomes.
RESUMO
BACKGROUND: Heart rate variability (HRV), defined as the variability between successive heart beats, is a noninvasive measure of autonomic nervous system (ANS) function, which may be altered following traumatic brain injury (TBI). This scoping review summarizes the existing literature regarding changes in HRV after TBI as well as the association between measures of HRV and outcomes following TBI. METHODS: A literature search for articles assessing 'heart rate variability' and 'brain injury' or 'concussion' was completed. Articles were included if HRV was measured in human subjects with TBI or concussion. Review articles, protocol papers, and studies including non-traumatic injuries were excluded. RESULTS: Sixty-three articles were included in this review. Varied methods were used to measure HRV in the different studies. Forty articles included information about differences in HRV measures after TBI and/or longitudinal changes after TBI. Fifteen studies assessed HRV and symptoms following TBI, and 15 studies assessed HRV and either functional or cognitive outcomes after TBI. CONCLUSIONS: HRV has been studied in the context of mortality, clinical symptoms, and medical, functional, or cognitive outcomes following TBI. Methods used to measure HRV have varied amongst the different studies, which may impact findings, standardized protocols are needed for future research.

OBJECTIVE: To explore the usability of and satisfaction with telerehabilitation services provided to rehabilitation patients with various diagnoses at two large urban medical facilities during the Covid-19 pandemic. DESIGN: This was a usability study and all patients that received telerehabilitation services from March 2020 to November 2021 were included. Of the 4,070 surveys sent via mail or email links to RedCap, 405 were completed (10% Response Rate). Participants completed demographic surveys, surveys on the telerehabilitation visit characteristics, telerehabilitation usability, and overall satisfaction with the visit. RESULTS: Patients were mostly women (64.4%), White, non-hispanic (74.3%) and English speaking (99%). Most patients were seen via telerehabilitation due to Covid-19 restrictions (37.1%). Patients were generally satisfied with their telerehabilitation visit (3.64 out of 4). Additionally, patients generally found telerehab to be useful (6.4 out of 7), easy to use (6.3 out of 7), effective (6.2 out of 7), satisfactory (6.3 out of 7) and comparable to in-person visits (6.5 out of 7). CONCLUSION: Patients generally reported feeling satisfied and comfortable with telerehabilitation visits, and felt they were comparable to in-person visits. Future research should examine the impact of socioeconomic factors on telerehabilitation use, with a focus on education level and non-English speakers.
RESUMO
The Behavioral Assessment Screening Tool (BAST) measures self-reported neurobehavioral symptoms commonly experienced by adults with traumatic brain injury (TBI). To assess the convergent, discriminant, and known-groups validity of the BAST among community-dwelling adults with chronic traumatic brain injury (TBI), we conducted correlation analyses and tests of group differences with previously validated symptom measures in two samples (n = 111, n = 134). Measures used for comparison were: Patient Health Questionnaire (depression), Generalized Anxiety Disorder-7 (anxiety), Positive and Negative Affect Schedule, Frontal Systems Behavior Scale (Executive Dysfunction, Apathy, Disinhibition), Modified Fatigue Impact Scale, PROMIS Fatigue, Aggression Questionnaire (anger, hostility, physical and verbal aggression), and Alcohol Use Disorders Test (alcohol misuse). BAST subscales had stronger correlations with measures of similar (|r|=.602-.828, p < .001) and related (|r|>.30, p < .001) constructs and weaker correlations (|r|<.300) with measures of dissimilar/unrelated constructs, supporting hypotheses of convergent and discriminant validity, respectively. Statistically significant group differences (p's < .001) in BAST subscales were found, with large effect sizes (Cohen's d = 1.2-1.9), for known-groups with moderate-severe depression, moderate-severe anxiety, clinically significant fatigue, problematic disinhibited and frontal-executive behaviors, and alcohol use. Conclusions: Results support the convergent and discriminant validity of the BAST subscales. The BAST was specifically developed as a self-reported measure for remote symptom reporting, supporting its incorporation into mobile health platforms to improve chronic symptom monitoring in community-dwelling adults with TBI. With further validation research, the BAST could be used for early identification of persons with TBI who could benefit from intervention.
RESUMO
OBJECTIVES: To determine the association between self-reported emotional and cognitive symptoms and participation outcomes in chronic traumatic brain injury (TBI) and to explore the relative contribution of self-reported versus performance-based cognition to participation outcomes. SETTING: Community. PARTICIPANTS: Community-dwelling adults ( n = 135) with a lifetime history of mild to severe TBI. DESIGN: Secondary analysis of a cross-sectional study on neurobehavioral symptoms in chronic TBI. MAIN MEASURES: Behavioral Assessment Screening Tool (BAST) (Negative Affect, Fatigue, Executive Dysfunction, Impulsivity, Substance Abuse subscales) measured self-reported neurobehavioral symptoms; Participation Assessment with Recombined Tools (Productivity, Social Relations, and Out and About) measured self-reported participation outcomes; and Brief Test of Adult Cognition by Telephone (BTACT) measured performance-based cognition (Episodic Memory and Executive Function summary scores) in a subsample ( n = 40). RESULTS: The BAST Executive Dysfunction was significantly associated with less frequent participation and had the strongest effect on participation in all participation domains. No other BAST subscales were associated with participation, after adjusting for all subscale scores and age, with the exception of BAST Impulsivity, which was associated with more frequent Social Relationships. Exploratory analysis in the sample including the BTACT revealed that, after accounting for subjective Executive Dysfunction using the BAST, performance-based Executive Function was associated with Productivity and Working Memory was associated with Social Relations, but neither was associated with being Out and About; the BAST Executive Dysfunction remained significant in all models even after including BTACT scores. CONCLUSIONS: Self-reported Executive Dysfunction contributed to participation outcomes after mild to severe TBI in community-dwelling adults, whereas self-reported emotional and fatigue symptoms did not. Performance-based cognition measures may capture different variability in participation after injury.

Children with chronic illnesses report being bullied by peers, yet little is known about bullying among children with heart conditions. Using 2018-2020 National Survey of Children's Health data, the prevalence and frequency of being bullied in the past year (never; annually or monthly; weekly or daily) were compared between children aged 6-17 years with and without heart conditions. Among children with heart conditions, associations between demographic and health characteristics and being bullied, and prevalence of diagnosed anxiety or depression by bullying status were examined. Differences were assessed with chi-square tests and multivariable logistic regression using predicted marginals to produce adjusted prevalence ratios and 95% confidence intervals. Weights yielded national estimates. Of 69,428 children, 2.2% had heart conditions. Children with heart conditions, compared to those without, were more likely to be bullied (56.3% and 43.3% respectively; adjusted prevalence ratio [95% confidence interval] = 1.3 [1.2, 1.4]) and bullied more frequently (weekly or daily = 11.2% and 5.3%; p < 0.001). Among children with heart conditions, characteristics associated with greater odds of weekly or daily bullying included ages 9-11 years compared to 15-17 years (3.4 [2.0, 5.7]), other genetic or inherited condition (1.7 [1.0, 3.0]), ever overweight (1.7 [1.0, 2.8]), and a functional limitation (4.8 [2.7, 8.5]). Children with heart conditions who were bullied, compared to never, more commonly had anxiety (40.1%, 25.9%, and 12.8%, respectively) and depression (18.0%, 9.3%, and 4.7%; p < 0.01 for both). Findings highlight the social and psychological needs of children with heart conditions.
RESUMO
Post-Concussion Syndrome (PCS) refers to the persistence of physical, cognitive, and emotional symptoms following mild traumatic brain injury (mTBI)/concussion, occurring in roughly 15-30% of individuals. Hyperbaric oxygen therapy (HBOT) has been suggested as a potential treatment for PCS; however, the evidence to date is mixed due to inconsistencies in the treatment protocol and focus on veterans with combat-related injuries, which may not be generalizable to the general population. The goal of Hyperbaric Oxygen Therapy for Post-Concussion Syndrome (HOT-POCS) is to assess the efficacy and safety of HBOT for the treatment of PCS in the civilian population. This randomized, controlled pilot study will be using a standardized HBOT protocol (20 sessions of 100% O2 at 2.0 atm absolute [ATA]) compared with a true placebo gas system that mimics the oxygen composition at room air (20 sessions of 10.5% O2 and 89.5% nitrogen at 2.0 ATA) in a cohort of 100 adults with persistent post-concussive symptoms 3-12 months following injury. Change in symptoms on the Rivermead Post-concussion Questionnaire (RPQ) will be the primary outcome of interest. Secondary outcomes include the rate of adverse events, change in the quality of life, and change in cognitive function. Exploratory outcome measures will include changes in physical function and changes in cerebral brain perfusion and oxygen metabolism on MRI brain imaging. Overall, the HOT-POCS study will compare the efficacy of a standardized HBOT treatment protocol against a true placebo gas for the treatment of PCS within 12 months after injury.
RESUMO
BACKGROUND: Cystic fibrosis transmembrane conductance regulator (CFTR) modulators have shown beneficial effects on both forced expiratory volume in 1 s (FEV1 ) and frequency of pulmonary exacerbations in people with cystic fibrosis (CF). These positive outcomes may be related to changes in bacterial colonization within the lungs. Elexacaftor/tezacaftor/ivacaftor (ELX/TEZ/IVA) is the first triple therapy CFTR modulator approved for use in people with CF 6 years and older. This study aimed to determine the impact of ELX/TEZ/IVA on the isolation of Pseudomonas aeruginosa (Pa), methicillin-resistant and methicillin-susceptible Staphylococcus aureus (MRSA and MSSA, respectively) in respiratory cultures. METHODS: A retrospective chart review of the electronic medical record at the University of Iowa was completed for individuals 12 years and older taking ELX/TEZ/IVA for at least 12 months. The primary outcome was determined by assessing bacterial cultures pre- and postinitiation of ELX/TEZ/IVA. Baseline demographic and clinical characteristics were summarized using mean and standard deviation for continuous outcomes and count and percentage for categorical outcomes. Culture positivity for Pa, MSSA, and MRSA was compared among enrolled subjects between pre- and posttriple combination therapy periods using an exact McNemar's test. RESULTS: One hundred and twenty-four subjects prescribed ELX/TEZ/IVA for at least 12 months met the requirements for inclusion within our analysis. Culture positivity for Pa, MSSA, and MRSA was approximately 54%, 33%, and 31%, respectively, for the pre-ELX/TEZ/IVA period. Prevalence decreased to approximately 30%, 32%, and 24% (-24.2% [p < 0.0001], -0.7% [p = 1.00], and -6.5% [p = 0.0963], respectively) post-ELX/TEZ/IVA. The source of bacterial culture was predominantly sputum (70.2%) in the pre-ELX/TEZ/IVA group, whereas a throat source (66.1%) was more common post-ELX/TEZ/IVA. CONCLUSIONS: ELX/TEZ/IVA treatment has an appreciable impact on the detection of common bacterial pathogens in CF respiratory cultures. While previous studies have found a similar effect with single and double CFTR modulator therapies, this is the first single-center study to show the impact of triple therapy, ELX/TEZ/IVA, on bacterial isolation from airway secretions.

BACKGROUND: Problem-Solving Training (PST) during inpatient rehabilitation could provide care partners the skills needed to manage their life roles after discharge. OBJECTIVE: Determine the feasibility of PST+ Education versus Education for care partners of adults with traumatic brain injury (TBI) during inpatient rehabilitation. METHODS: We conducted a multisite randomized feasibility trial across three sites. We present recruitment rates, reasons for refusal to participate, and reasons for non-completion of interventions. We measured client satisfaction, participant engagement, and fidelity for both interventions. We compared change in depressive symptoms and caregiver burden between PST and Education groups. RESULTS: Though the interventions were generally feasible, recruitment and retention rates were lower than anticipated largely due to the COVID-19 pandemic. Participants who completed >3 sessions were less likely to be employed full-time and more often spouses and co-residing. Length of inpatient rehabilitation stay was correlated with number of sessions completed. We observed potential benefits of PST over Education, specifically for reducing depression symptoms and caregiver burden. CONCLUSION: High satisfaction, engagement, and fidelity, overall recruitment and retention, and positive change in outcomes suggest that PST is generally feasible and beneficial for care partners of persons with TBI. Adaptations, such as developing a 3-session version of PST, could improve feasibility.

OBJECTIVES: To develop and evaluate the feasibility of a short form of the Behavioral Assessment Screening Tool (BASTmHealth) for high frequency in situ self-reported assessment of neurobehavioral symptoms using mobile health technology for community-dwelling adults with traumatic brain injury (TBI). DESIGN: Prospective, repeated-measures study of mHealth assessment of self-reported neurobehavioral symptoms in adults with and without a lifetime history of TBI over a 2-week period. SETTING: Community. PARTICIPANTS: Community-dwelling adults with (n=52) and without (n=12) a lifetime TBI history consented to the study (N=64). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: BASTmHealth subscales (2-items each): negative affect, fatigue, executive function, substance abuse, impulsivity; feasibility measured via compliance (assessments assigned/assessments completed) and participant-reported usability. RESULTS: We developed the 10-item BASTmHealth as a screener for high frequency in situ self-reported assessment of neurobehavioral symptoms leveraging mHealth. Compliance for 2 weeks of BASTmHealth supports its feasibility. Fifty-six of 64 participants (87.5%) who completed baseline assessments completed the 2 weeks of daily assessments; all 8 participants who did not complete ecological momentary assessment had a history of TBI. Overall compliance was 81.4% (496 completed of 609 assigned assessments) among all 52 participants with TBI and 96.7% (494 completed of 511 assigned assessments) among the 44 who completed any daily measures, compared with 91.8% (135 completed of 147 assigned assessments) among those with no TBI history. Participants thought the daily surveys were easy to understand and complete and the number of prompts were reasonable. CONCLUSIONS: Conducting daily high-frequency in situ self-reported assessment of neurobehavioral symptoms using the BASTmHealth is feasible among individuals with and without a lifetime history of TBI. Developing and evaluating self-reported assessments for community-based assessment is a critical step toward expanding remote clinical monitoring systems to improve post-TBI outcomes.
