Shift-Level Team Familiarity Is Associated with Improved Outcomes in Mechanically Ventilated Adults.

Rationale: Organizing ICU interprofessional teams is a high priority because of workforce needs, but the role of interprofessional familiarity remains unexplored. Objectives: Determine if mechanically ventilated patients cared for by teams with greater familiarity have improved outcomes, such as lower mortality, shorter duration of mechanical ventilation (MV), and greater spontaneous breathing trial (SBT) implementation. Methods: We used electronic health records data of five ICUs in an academic medical center to map interprofessional teams and their ICU networks, measuring team familiarity as network coreness and mean team value. We used patient-level regression models to link team familiarity with patient outcomes, accounting for patient and unit factors. We also performed a split-sample analysis by using 2018 team familiarity data to predict 2019 outcomes. Measurements and Main Results: Team familiarity was measured as the average number of patients shared by each clinician with all other clinicians in the ICU (i.e., coreness) and the average number of patients shared by any two members of the team (i.e., mean team value). Among 4,485 encounters, unadjusted mortality was 12.9%, average duration of MV was 2.32 days, and SBT implementation was 89%; average team coreness was 467.2 (standard deviation [SD], 96.15), and average mean team value was 87.02 (SD, 42.42). A 1-SD increase in team coreness was significantly associated with a 4.5% greater probability of SBT implementation, 23% shorter MV duration, and 3.8% lower probability of dying; the mean team value was significantly associated with lower mortality. Split-sample results were attenuated but congruent in direction and interpretation. Conclusions: Interprofessional familiarity was associated with improved outcomes; assignment models that prioritize familiarity might be a novel solution.

Racial and Ethnic Disparities in Home Health Referral Among Adult Medicare Patients.

BACKGROUND: Home health care (HHC) services following hospital discharge provide essential continuity of care to mitigate risks of posthospitalization adverse outcomes and readmissions, yet patients from racial and ethnic minority groups are less likely to receive HHC visits. OBJECTIVE: To examine how the association of nurse assessments of patients' readiness for discharge with referral to HHC services at the time of hospital discharge differs by race and ethnic minority group. RESEARCH DESIGN: Secondary data analysis from a multisite study of the implementation of discharge readiness assessments in 31 US hospitals (READI Randomized Clinical Trial: 09/15/2014-03/31/2017), using linear and logistic models adjusted for patient demographic/clinical characteristics and hospital fixed effects. SUBJECTS: All Medicare patients in the study's intervention arm (n=14,684). MEASURES: Patient's race/ethnicity and discharge disposition code for referral to HHC (vs. home) from electronic health records. Patient's Readiness for Hospital Discharge Scale (RHDS) score (0-10 scale) assessed by the discharging nurse on the day of discharge. RESULTS: Adjusted RHDS scores were similar for non-Hispanic White (8.21; 95% CI: 8.18-8.24), non-Hispanic Black (8.20; 95% CI: 8.12-8.28), Hispanic (7.92; 95% CI: 7.81-8.02), and other race/ethnicity patients (8.09; 95% CI: 8.01-8.17). Non-Hispanic Black patients with low RHDS scores (6 or less) were less likely than non-Hispanic White patients to be discharged with an HHC referral (Black: 26.8%, 95% CI: 23.3-30.3; White: 32.6%, 95% CI: 31.1-34.1). CONCLUSIONS: Despite similar RHDS scores, Black patients were less likely to be discharged with HHC. A better understanding of root causes is needed to address systemic structural injustice in health care settings.

Development and Preliminary Evaluation of a Bimodal Foot Prosthesis for Walking and Running.

People often alternate between bouts of walking and running, for instance, when adults participate in recreational activities. Transitioning between activities can be challenging for prosthesis users because existing prosthetic feet are not well-suited for both tasks. Meanwhile, switching between prostheses for different tasks is often impractical. Collectively, these challenges can present barriers to physical activity participation for people with limb loss, which can negatively impact social or physical health. This work describes the development and evaluation of a passive bimodal prosthetic foot prototype with different configurations and stiffnesses for walking and running. Users rated the bimodal prosthesis higher for standing and walking compared to a running prosthesis (+2.3 for both tasks on a seven-point Likert scale). Users rated the bimodal prosthesis higher for running compared to a walking prosthesis (+1.7 and +0.5 for 2.0 and 2.5 m/s running, respectively). Changing from walking to running mode increased the device's stiffness by 23-84%, depending on the user's preference. Users could switch between bimodal prosthesis walking and running modes quickly (21.3 ± 12.0 s). Overall, the preliminary results were encouraging in terms of user satisfaction, stiffness change between modes, and mode-switching speed. These findings motivate future exploration of this bimodal prosthesis concept.

Complementary and Alternative Medicine for Hidradenitis Suppurativa Discussed on TikTok: A Cross-Sectional Analysis.

BACKGROUND: Hidradenitis suppurativa (HS) is a painful, chronic inflammatory skin disease that negatively affects patient quality of life, and conventional treatments are variably effective. As a result, patients often turn to complementary and alternative medicine (CAM) for pain relief. Social media enables HS patients to share treatment recommendations. TikTok is a popular social media platform, but little is known about the HS treatments discussed in TikTok videos.  Objective: To evaluate the content and quality of information on TikTok regarding CAM HS therapies.  Methods: A cross-sectional analysis was conducted by performing a search in TikTok using the terms #hidradenitissuppurativa, #hswarrior, #naturalremedy, #complementarymedicine, #alternativemedicine, and #HStreatment. Two independent reviewers evaluated video quality using the DISCERN and AVA instruments. Linear regressions compared the engagement, DISCERN, and AVA scores among different uploader types. RESULTS: In total, 91 TikTok videos were analyzed. Videos were uploaded by non-physicians (82.4), dermatologists (6.6%), and private companies (11.0%). The average DISCERN and AVA scores were 36.2 and 1.6, respectively (poor quality). Common CAM therapies were natural salves, turmeric, Epsom salts, elimination diets, and zinc supplements. Physician-uploaded videos were of significantly higher quality than videos by other uploader types, with an average DISCERN and AVA score of 44.3 (P<0.009) and 2.6 (P<0.001), respectively (fair quality). CONCLUSION: TikTok videos were poor quality (low DISCERN and AVA scores); physician-uploaded videos were fair quality. Dermatologists can improve video quality by adequately discussing the supporting evidence, mechanisms of action, and remaining questions for HS treatments.  J Drugs Dermatol. 2024;23(3):e93-96. doi:10.36849/JDD.7738e.

The Hidden Costs of Psoriasis: A Population-Based Study Evaluating How Psoriasis Severity Impacts Work Absenteeism.

BACKGROUND: Psoriasis patients experience physical and emotional burdens, which may lead to work-related productivity loss. This loss carries professional and financial repercussions. It is unknown whether the extent of psoriasis affects work absenteeism. OBJECTIVE: This study aims to compare work absenteeism between employed adults with mild versus moderate-to-severe psoriasis. METHODS: A national, cross-sectional study using the 2009 to 2019 Medical Expenditure Panel Survey evaluated 5,209,956 (weighted) adults aged ≥ 22 years. Work absenteeism was compared between adults with mild (4,521,687 weighted) and moderate-to-severe psoriasis (688,269 weighted). RESULTS: Work absenteeism, as measured by the average number of episodes per year that someone was absent from work for at least a half day, was significantly higher in patients with moderate-to-severe psoriasis than in patients with mild disease (4.4 episodes vs 2.8 episodes, P=0.002). Multivariable logistic regression models showed moderate-to-severe patients were 2.68 times more likely (95% CI:1.72-4.21; P<0.001) to take a half-day or more off from work than those with mild disease after adjusting for age, sex, race, ethnicity, poverty, cognitive limitations, insurance, education, and comorbidities. CONCLUSION: Disease severity directly impacts work absenteeism in psoriasis patients. Early diagnosis and treatment with appropriate therapies are needed to reduce disease severity and limit economic loss and professional ramifications associated with psoriasis.

Patterns and Correlates of Nurse Departures From the Health Care Workforce: Results From a Statewide Survey.

BACKGROUND: Health care executives and policymakers have raised concerns about the adequacy of the US nursing workforce to meet service demands. Workforce concerns have risen given the SARS-CoV-2 pandemic and chronically poor working conditions. There are few recent studies that directly survey nurses on their work plans to inform possible remedies. METHODS: In March 2022, 9150 nurses with a Michigan license completed a survey on their plans to leave their current nursing position, reduce their hours, or pursue travel nursing. Another 1224 nurses who left their nursing position within the past 2 years also reported their reasons for departure. Logistic regression models with backward selection procedures estimated the effects of age, workplace concerns, and workplace factors on the intent to leave, hour reduction, pursuit of travel nursing (all within the next year), or departure from practice within the past 2 years. RESULTS: Among practicing nurses surveyed, 39% intended to leave their position in the next year, 28% planned to reduce their clinical hours, and 18% planned to pursue travel nursing. Top-ranked workplace concerns among nurses were adequate staffing, patient safety, and staff safety. The majority of practicing nurses (84%) met the threshold for emotional exhaustion. Consistent factors associated with adverse job outcomes include inadequate staffing and resource adequacy, exhaustion, unfavorable practice environments, and workplace violence events. Frequent use of mandatory overtime was associated with a higher likelihood of departure from the practice in the past 2 years (Odds Ratio 1.72, 95% CI 1.40-2.11). CONCLUSIONS: The factors associated with adverse job outcomes among nurses-intent to leave, reduced clinical hours, travel nursing, or recent departure-consistently align with issues that predated the pandemic. Few nurses cite COVID as the primary cause for their planned or actual departure. To maintain an adequate nursing workforce in the United States, health systems should enact urgent efforts to reduce overtime use, strengthen work environments, implement anti-violence protocols, and ensure adequate staffing to meet patient care needs.

Shared decision-making and satisfaction with care in patients with psoriasis: A population-based study in the United States.

BACKGROUND: Shared decision-making (SDM) is a critical component of the patient-physician relationship. Although SDM has been reported to improve patient knowledge in other fields, it is still relatively unknown in dermatology. OBJECTIVE: To determine the association between SDM and satisfaction with care among patients with psoriasis. METHODS: Cross-sectional study using data from the 2014 to 2017 and 2019 Medical Expenditure Panel Survey. RESULTS: A weighted total of 3,715,027 patients with psoriasis were identified. The average SDM score was 3.6 (of 4), and the average satisfaction with care score was 8.6 (of 10). Approximately 42% of the cohort reported having a high SDM (score, ≥3.9). Patients who had high SDM had, on average, 85% higher satisfaction with care (P < .001) after adjusting for covariates. LIMITATIONS: The results of our study should be interpreted within the context of the Medical Expenditure Panel Survey database. The ability to measure SDM was limited by the 7 items from Medical Expenditure Panel Survey, which may not fully capture active participation in shared decision-making. CONCLUSION: A majority of patients with psoriasis are not participating in highly SDM. It is important to construct a framework for carrying out SDM efficiently to enhance physician-patient communication and improve patient outcomes.

Inhibiting with-no-lysine kinases enhances K+/Cl- cotransporter 2 activity and limits status epilepticus.

First-in-line benzodiazepine treatment fails to terminate seizures in about 30% of epilepsy patients, highlighting a need for novel anti-seizure strategies. It is emerging that impaired K+/Cl- cotransporter 2 (KCC2) activity leads to deficits in GABAergic inhibition and increased seizure vulnerability in patients. In neurons, the with-no-lysine (WNK) kinase-STE20/SPS1-related proline/alanine-rich (SPAK) kinase signalling pathway inhibits KCC2 activity via T1007 phosphorylation. Here, we exploit the selective WNK kinase inhibitor WNK463 to test the effects of pharmacological WNK inhibition on KCC2 function, GABAergic inhibition, and epileptiform activity. Immunoprecipitation and western blotting analysis revealed that WNK463 reduces KCC2-T1007 phosphorylation in vitro and in vivo. Using patch-clamp recordings in primary rat neurons, we further observed that WNK463 hyperpolarized the Cl- reversal potential, and enhanced KCC2-mediated Cl- extrusion. In the 4-aminopyridine slice model of acute seizures, WNK463 administration reduced the frequency and number of seizure-like events. In vivo, C57BL/6 mice that received intrahippocampal WNK463 experienced delayed onset of kainic acid-induced status epilepticus, less epileptiform EEG activity, and did not develop pharmaco-resistance to diazepam. Our findings demonstrate that acute WNK463 treatment potentiates KCC2 activity in neurons and limits seizure burden in two well-established models of seizures and epilepsy. In summary, our work suggests that agents which act to increase KCC2 activity may be useful adjunct therapeutics to alleviate diazepam-resistant status epilepticus.

Shared decision-making and satisfaction with care: a population-based study in patients with acne with skin of colour in the USA.

Little is known about differences in shared decision-making and patient satisfaction with acne care among different ethnicities and races. We conducted a cross-sectional study to determine differences between patients with acne who are White and those with skin of colour (SOC), i.e. (i) engagement in shared decision-making, and (ii) patient satisfaction with care, using the 2009-2017 and 2019 Medical Panel Expenditure Survey. Patients with acne with SOC were nearly two times more likely to engage in high shared decision-making compared with White patients [adjusted odds ratio 1.80, 95% confidence interval (CI) 1.30-2.51, P < 0.001]. Patients with SOC with acne reported lower satisfaction with care compared with White patients (ß = -0.38, 95% CI -0.69 to -0.06, P = 0.02). Patients with SOC who had acne reported higher levels of shared decision-making than White patients. However, compared with the White patients, patients with SOC report lower satisfaction with their care. There may be other factors contributing to lower satisfaction with care in patients with SOC who have acne.

Validation of a short version of the Lee fatigue scale in adults living in Norway: a cross-sectional population survey.

BACKGROUND: Due to the nature of fatigue, a brief reliable measure of fatigue severity is needed. Thus, the aim of our study was to evaluate a short version of the Lee Fatigue Scale (LFS) in the Norwegian general population. METHODS: This cross-sectional survey consists of a representative sample from the Norwegian population drawn by The National Population Register in Norway. The study is part of a larger study (NORPOP) aimed at collecting normative data from several questionnaires focused on health in adults living in Norway. Registered citizens between 18 and 94 years of age were randomly selected stratified by age, sex and geographic region. Of the 4971 respondents eligible for the study, 1792 (36%) responded to the survey. In addition to age and sex, we collected responses on a 5-item version of the LFS measuring current fatige severity. The psychometric properties focusing on internal structure and precision of the LFS items were analyzed by a Rasch rating scale model. RESULTS: Complete LFS scores for analyses were available for 1767 adults. Women had higher LFS-scores than men, and adults < 55 years old had higher scores than older respondents. Our analysis of the LFS showed that the average category on each item advanced monotonically. Two of the five items demonstrated misfit, while the three other items demonstrated goodness-of-fit to the model and uni-dimensionality. Items #1 and #4 (tired and fatigue respectively) showed differential item functioning (DIF) by sex, but no items showed DIFs in relation to age. The separation index of the LFS 3-item scale showed that the sample could be separated into three different groups according to the respondents' fatigue levels. The LFS-3 raw scores correlated strongly with the Rasch measure from the three items. The core dimensions in these individual items were very similarly expressed in the Norwegian language version and this may be a threat to the cultural-related or language validity of a short version of the LFS using these particular items. CONCLUSIONS: The study provides validation of a short LFS 3-item version for estimating fatigue in the general population.

INDIVIDUAL ARTICLE: Vehicles Matter: Calcipotriene and Betamethasone Dipropionate Foam as a Topical Psoriasis Therapy.

Topical medications are commonly used to manage mild-to-moderate psoriasis and serve as adjunct therapies used in combination with phototherapy and systemic treatments. Fixed-dose calcipotriene (Cal) 0.005%/betamethasone dipropionate (BD) 0.064% aerosol foam is a safe, efficacious topical therapy approved for the treatment of psoriasis vulgaris in the United States and European Union. Several investigator-initiated studies (IISs) have been conducted to provide real-world evidence related to the safety, effectiveness, and therapeutic indications of Cal/BD foam and are relevant to clinicians' every-day practice. This paper summarizes the findings of the IISs around the globe published to date and presents the real-world data related to the effectiveness and clinical considerations of Cal/BD foam as a treatment for psoriasis.

Victimology of Mass Shootings and Mass Murders Not Involving Firearms.

Most research to date has focused on perpetrators of mass murder incidents. Hence, there is little information on victims. We examined 973 mass murders that occurred in the United States between 1900 and 2019 resulting in 5,273 total fatalities and 4,498 nonfatal injuries for a total of 9,771 victims (on average 10 victims per incident). Approximately 64% of victims of mass murder were White individuals, 13% were Black individuals, 6% were Asian individuals, and 14% were Latinx individuals. Given the higher number of nonfatal injuries per non-firearm mass murder event (11.0 vs. 2.8, p < .001), the total number of victims was only 50% higher for mass shootings (5,855 victims) vs. non-firearm mass murder events (3,916 victims). Among the 421 incidents of mass murder in the United States since 2000, Black, Asian, and Native American individuals were overrepresented among victims of mass shootings compared with their representation in the general U.S. population, and White individuals were underrepresented (all p ≤ .002). Findings of racial/ethnic differences were similar among victims of mass murder committed with means other than firearms for Black, Asian, and White individuals. These findings highlight different areas of victimology within the context of these incidents.

Factors Associated with Use of HIV Prevention and Health Care Among Transgender Women - Seven Urban Areas, 2019-2020.

Transgender women* are disproportionately affected by HIV. Among 1,608 transgender women who participated in CDC's National HIV Behavioral Surveillance (NHBS) during 2019-2020, 42% received a positive HIV test result (1). This report provides results from seven U.S. urban areas where the 2019-2020 NHBS questionnaire was administered. Thirty-eight percent of participants reported having previously received a positive test result for HIV. Detrimental socioeconomic factors, including low income (44%), homelessness (39%), and severe food insecurity in the past 12 months (40%), were common and associated with lower receipt of HIV prevention and treatment services. Having a usual health care source or a provider with whom the participant was comfortable discussing gender-related health issues was associated with improved HIV prevention and treatment outcomes, including HIV testing, preexposure prophylaxis (PrEP) use, and viral suppression. These findings illustrate the benefit of gender-affirming approaches used by health care providers (2), and highlight the challenging socioeconomic conditions faced by many transgender women. Ensuring access to gender-affirming health care approaches and addressing the socioeconomic challenges of many transgender women could improve access to and use of HIV prevention and care in this population and will help achieve the goals of the Ending the HIV Epidemic in the United States initiative (3).

Perceived risk for diabetes among U.S. adults with undiagnosed prediabetes.

The purpose was to examine the degree to which perceived risk for diabetes differed by race and ethnicity among U.S. adults with undiagnosed prediabetes. The study was a cross-sectional analysis of data from 4005 participants (aged ≥20 years) in the National Health and Nutrition Examination Survey (NHANES) program between 2011 and 2018. Individuals with prediabetes were identified using glycohemoglobin (HbA1c) data. Logistic regression was used to estimate the association between race and ethnicity and perceived risk of diabetes while adjusting for age and sex, educational level, family history of diabetes, BMI, and healthcare factors (health insurance coverage and routine place to go for healthcare). Nearly three-quarters (71.8%) of adults with undiagnosed prediabetes reported no perceived risk for diabetes. Rates of perceived risk for diabetes did not change significantly in any racial and ethnic groups from 2011 to 12 to 2017-18. In models adjusted for individual characteristics, identifying as Non-Hispanic Black was associated with a 34% higher likelihood of reporting no perceived risk compared to identifying as Non-Hispanic White (OR 1.34, 95% CI:1.03-1.74). Identifying as Hispanic was associated with a 29% higher likelihood of reporting no perceived risk compared to identifying as Non-Hispanic White (OR 1.29, 95% CI: 1.01, 1.66). Healthcare factors may have less influence on diabetes risk perception. Future public health efforts should improve diabetes risk communication efforts across racial and ethnic groups, emphasizing Non-Hispanic Black and Hispanic populations.

Effect of Timing of Intravenous Ketorolac Administration on Pain in Orbitotomy Surgery.

PURPOSE: Intravenous ketorolac (IVK) is an effective and safe medication to reduce postoperative pain in the setting of oculofacial surgery. This study was undertaken to determine the impact of timing of IVK administration in orbital surgery on the reduction of postoperative pain score and opioid requirement. METHODS: Patients either received IVK immediately before (n = 50), during (n = 50) or after (n = 50) orbital surgery or acted as controls (n = 50). Pain scores were assessed via an analog scale immediately after surgery and on the first postoperative day. The requirements for opioid analgesics were recorded. Statistical analyses were performed via a dedicated computerized software package. RESULTS: One hundred fifty patients received IVK; 50 before incision (28 males, 22 females, mean age 52.2), 50 intraoperatively (20 males, 30 females, mean age 49.8) and 50 in the immediate postoperative period (26 males, 24 females, mean age = 55.3). Additionally, 50 patients acted as controls (26 males, 24 females, mean age 54). Immediately after surgery, administration of IVK resulted in statistically significant reduction in pain score regardless of the timing of dosing as compared with control patients (prior = 2.36, intraoperative = 2.34, postoperative = 2.46 vs. control 5.44, p < 0.0001). Eleven patients (22%) in the control group required opioids, whereas, in the IVK cohorts, only 2 (4%-preoperative), 1 (2%-intraoperative), and 1 (2%-postoperative) patients needed these medications (p = 0.0039). CONCLUSIONS: In the setting of orbital surgery, IVK reduced pain scores and opioid requirement, regardless of the timing of administration, as compared with patients that did not receive the medication.

Orbital cellulitis secondary to sinusitis in upstate New York: current incidence, seasonality, severity, management and outcomes.

PURPOSE: While sinusitis carries a seasonal variation, the temporal features of sinusitis-related orbital cellulitis (SRC) are unclear. This study analyzes the incidence, seasonality, management, and outcomes of SRC in northeastern New York. METHODS: A retrospective review of 79 patients was performed from January 2008 - December 2018. Cases of orbital cellulitis without comitant sinusitis were excluded. Demographic, radiographic, clinical features, month at presentation, interventions (surgical and nonsurgical), microbiology, and hospitalization duration were recorded. Fisher-exact test, Mann-Whitney test, and Kruskal Wallis test statistical analyses were performed in consultation with our institution's statistician via a dedicated software package (vassarstats.net). RESULTS: 79 patients were admitted for SRC. 25 patients were treated with antibiotics only, 31 underwent orbitotomy exclusively and 23 received combined orbitotomy and functional endoscopic sinus surgery (FESS). Of the 31 patients who underwent orbitotomy only, 8 (26%) returned to the operating room. In contrast, of those who underwent concomitant orbitotomy and FESS, only one patient (4.3%) required re-operation (fisher exact test, p = .021). The median length of stay for the antibiotic-only group (4 days), orbitotomy-only group (6 days), and combined surgery group (5 days) were statistically different (Kruskal Wallis, p = .004, Figure 3). Interestingly, there was no significant relationship of incidence or severity of SRC related to seasonality (fisher-exact test, p = .76). CONCLUSION: Our findings suggest that cases requiring surgical management for SRC should undergo coinitial orbitotomy with FESS to reduce re-operation rates. Additionally, SRC incidence and severity did not correlate with season.

Psychotic symptoms in mass shootings v. mass murders not involving firearms: findings from the Columbia mass murder database.

BACKGROUND: Mass shootings account for a small fraction of annual worldwide murders, yet disproportionately affect society and influence policy. Evidence suggesting a link between mass shootings and severe mental illness (i.e. involving psychosis) is often misrepresented, generating stigma. Thus, the actual prevalence constitutes a key public health concern. METHODS: We examined global personal-cause mass murders from 1900 to 2019, amassed by review of 14 785 murders publicly described in English in print or online, and collected information regarding perpetrator, demographics, legal history, drug use and alcohol misuse, and history of symptoms of psychiatric or neurologic illness using standardized methods. We distinguished whether firearms were or were not used, and, if so, the type (non-automatic v. semi- or fully-automatic). RESULTS: We identified 1315 mass murders, 65% of which involved firearms. Lifetime psychotic symptoms were noted among 11% of perpetrators, consistent with previous reports, including 18% of mass murderers who did not use firearms and 8% of those who did (χ2 = 28.0, p < 0.01). US-based mass shooters were more likely to have legal histories, use recreational drugs or misuse alcohol, or have histories of non-psychotic psychiatric or neurologic symptoms. US-based mass shooters with symptoms of any psychiatric or neurologic illness more frequently used semi-or fully-automatic firearms. CONCLUSIONS: These results suggest that policies aimed at preventing mass shootings by focusing on serious mental illness, characterized by psychotic symptoms, may have limited impact. Policies such as those targeting firearm access, recreational drug use and alcohol misuse, legal history, and non-psychotic psychopathology might yield more substantial results.

A NeuroD1 AAV-Based Gene Therapy for Functional Brain Repair after Ischemic Injury through In Vivo Astrocyte-to-Neuron Conversion.

Adult mammalian brains have largely lost neuroregeneration capability except for a few niches. Previous studies have converted glial cells into neurons, but the total number of neurons generated is limited and the therapeutic potential is unclear. Here, we demonstrate that NeuroD1-mediated in situ astrocyte-to-neuron conversion can regenerate a large number of functional new neurons after ischemic injury. Specifically, using NeuroD1 adeno-associated virus (AAV)-based gene therapy, we were able to regenerate one third of the total lost neurons caused by ischemic injury and simultaneously protect another one third of injured neurons, leading to a significant neuronal recovery. RNA sequencing and immunostaining confirmed neuronal recovery after cell conversion at both the mRNA level and protein level. Brain slice recordings found that the astrocyte-converted neurons showed robust action potentials and synaptic responses at 2 months after NeuroD1 expression. Anterograde and retrograde tracing revealed long-range axonal projections from astrocyte-converted neurons to their target regions in a time-dependent manner. Behavioral analyses showed a significant improvement of both motor and cognitive functions after cell conversion. Together, these results demonstrate that in vivo cell conversion technology through NeuroD1-based gene therapy can regenerate a large number of functional new neurons to restore lost neuronal functions after injury.
