RESUMEN
To investigate the biological significance of Rho-associated coiled-coil-containing protein kinase (ROCK) 2 in the human trabecular meshwork (HTM), changes in both metabolic phenotype and gene expression patterns against a specific ROCK2 inhibitor KD025 were assessed in planar-cultured HTM cells. A seahorse real-time ATP rate assay revealed that administration of KD025 significantly suppressed glycolytic ATP production rate and increased mitochondrial ATP production rate in HTM cells. RNA sequencing analysis revealed that 380 down-regulated and 602 up-regulated differentially expressed genes (DEGs) were identified in HTM cells treated with KD025 compared with those that were untreated. Gene ontology analysis revealed that DEGs were more frequently related to the plasma membrane, extracellular components and integral cellular components among cellular components, and related to signaling receptor binding and activity and protein heterodimerization activity among molecular functions. Ingenuity Pathway Analysis (IPA) revealed that the detected DEGs were associated with basic cellular biological and physiological properties, including cellular movement, development, growth, proliferation, signaling and interaction, all of which are associated with cellular metabolism. Furthermore, the upstream regulator analysis and causal network analysis estimated IL-6, STAT3, CSTA and S1PR3 as possible regulators. Current findings herein indicate that ROCK2 mediates the IL-6/STAT3-, CSTA- and S1PR3-linked signaling related to basic biological activities such as glycolysis in HTM cells.
RESUMEN
Background: Because dementia is a long-term condition, the appropriate involvement of health-care professionals is considered important. However, little is known about the factors associated with changes in family caregiver burden. Objective: To clarify changes in family caregiver burden and associated factors during follow-up at a memory clinic. Methods: A retrospective cohort study was conducted, enrolling 495 pairs of patients with dementia or mild cognitive impairment and their family caregivers. A total of 120 pairs completed the second evaluation. The caregiver burden was assessed using the Zarit Burden Interview (ZBI). Data at the initial visit and after an average follow-up of about 2 years were compared and analyzed. Results: At initial visit, the patients' mean age, Mini-Mental State Examination (MMSE) and ZBI scores were 78.6±5.6 years, 23.3±3.5, and 22.6±16.7, respectively. At follow-up, MMSE scores decreased (21.4±4.5, pâ<â0.001), but ZBI scores remained similar (22.5±13.6). When the difference in ZBI scores between the two time points was defined as ΔZBI, and the related factors were analyzed by multiple regression analysis, ZBI scores at the initial visit, start of psychotropic drug, and decrease of neuropsychiatric symptoms were identified as significant factors (pâ<â0.001, pâ=â0.003, pâ<â0.001, respectively). A significant negative correlation was found between ZBI scores at the initial visit and ΔZBI (râ=â-0.588, pâ<â0.001). Conclusions: These findings suggest the importance of assessing changes in the burden experienced by family caregivers during the disease follow-up.
RESUMEN
This study analyzed the linguistic and psychometric validation of the Japanese version of the Quality of Life after Brain Injury-Overall Scale (QOLIBRI-OS) consisting of six items which cover several TBI-relevant domains. We hypothesized that the Japanese version has good reliability, convergent validity, and divergent validity, compared with its long version, the 37-item QOLIBRI. The QOLIBRI-OS Japanese version was forward and back-translated from the English version. In total, 129 individuals participated in this study after experiencing a traumatic brain injury and attending clinics, rehabilitation centers, and support centers in Japan. The structure of the QOLIBRI-OS was investigated by confirmatory factor analyses and compared with the QOLIBRI. Only one factor was extracted, and a model with one underlying factor had a good fit. The QOLIBRI-OS showed good-to-excellent internal consistency and test-retest reliability. The QOLIBRI-OS was positively correlated with the QOLIBRI, Short Form Health Survey-36 version 2, and Glasgow Outcome Scale Extended, and negatively correlated with the Hospital Anxiety and Depression Scale. The results suggest that the QOLIBRI-OS Japanese version is a reliable and valid tool for assessing disease-specific health-related QOL in individuals after traumatic brain injury in Japan.

Objectives: To predict falls by adding an adherence assessment to a static balance ability assessment, and to evaluate fall prediction accuracy. Methods: This study included 416 patients who were admitted to a 45-bed convalescent rehabilitation ward over a 2-year period. The patients were assessed at the time of admission using the Standing Test for Imbalance and Disequilibrium (SIDE) and three additional, newly developed adherence items. Patients were divided into two groups: a group that experienced falls (fall group) and a group that did not experience falls (non-fall group) within 14 days of admission. The sensitivity and specificity of the assessment items for predicting falls were calculated. Results: Sensitivity was 0.86 and specificity was 0.42 when the cutoff was between SIDE levels 0-2a and 2b-4. Combining balance assessment using the SIDE with the memory and instruction adherence items improved fall prediction accuracy such that the sensitivity was 0.75 and the specificity was 0.64. Conclusions: Our analysis suggested that adherence assessment can improve fall risk prediction accuracy.
RESUMEN
Objective: An automated breast ultrasound system (ABUS) combined with screening mammography has increased cancer detection rates; however, supplemental ABUS use has increased recall rates. In this study, we aimed to identify an accurate and efficient method of ABUS interpretation and evaluate the potential usefulness of its coronal view versus the conventional transverse view. Materials and Methods: This retrospective observer study included comprised 114 ABUS cases (40 normal, 35 benign, 39 malignant). Ten physicians from multiple institutions interpreted the anonymized coronal and transverse views independently. The observers scored their confidence in the lesion detection for each case using a continuous scale and recorded reading times for each coronal and transverse view interpretation. Free-response receiver operating characteristic analysis was employed to compare detection accuracies between views; a paired t-test was used to compare the average reading times. Results: Detection accuracy did not differ significantly between the coronal and transverse views (figure of merit=0.740 and 0.745, respectively; p = 0.72). However, the average reading time for the coronal view was significantly shorter than that for the transverse view (149.7 vs. 200.3 seconds per case, p = 0.003). Conclusion: The coronal view obtained with the ABUS was useful for interpretation and associated with significantly shorter reading times compared with the conventional transverse view while maintaining breast lesion detection accuracy.
RESUMEN
Objectives: The purpose of this study was to capture the lifestyle characteristics of traumatic brain injury (TBI) patients by administering the Frenchay Activities Index (FAI), a self-assessment questionnaire used for assessing life-related activities, among TBI patients. Methods: This study was conducted using the revised FAI Self-Assessment Form, administering an interview-based questionnaire survey to TBI patients and healthy participants. The target group comprised 60 traumatic brain injury patients who had progressed from at least 1 year since the injury, with a comparison group of 788 healthy participants. Results: A comparison of FAI scores between TBI patients and healthy participants by questionnaire revealed that TBI patients exhibited significantly higher FAI scores than healthy participants for outdoor walking and transportation use (Mann-Whitney U test, P<0.01). A comparison by occupation revealed that TBI patients were significantly less among the unemployed and other categories (Mann-Whitney U test, P<0.01). For office workers, government employees, high school students, and college students, scores were higher among TBI patients compared with healthy participants, although the differences were not significant. Conclusions: Although TBI patients were less active than healthy participants in life-related activities, their scores for cleaning up after meals and cleaning and putting things in order were close to those of healthy participants, indicating that TBI patients cannot be considered to be inactive. The findings also revealed differences in TBI patients' engagement in life-related activities and frequency of activities depending on their social position.
RESUMEN
Objective: To evaluate the effectiveness of a dyadic outpatient rehabilitation program focused on improving the real-life daily activities of patients with mild cognitive impairments or dementia and their caregivers. Design: Retrospective study. Subjects: Eight patients with mild cognitive impairments or dementia and their caregivers. Methods: The rehabilitation program comprised eight 1-hour sessions by occupational therapists with patients and his/her caregivers. Patients were assessed for motor function, cognitive function, and quality of life, and their caregivers were assessed for depression and caregiver burden. Participants were assessed at pre-program and post-program, and 3-month follow-up. Results: The scores of caregiver-assessed Quality of life in Alzheimer's disease scale in patients significantly improved at post-program (median [interquartile range], 30.0 [7.0]) compared with pre-program (27.0 [2.8], effect size = 0.77, p = 0.029). In caregivers, the Zarit Caregiver Burden Interview scores decreased significantly at post-program (16.5 [13.0]) compared with pre-program (22.0 [17.5], effect size = 0.72, p = 0.042). There were no significant differences in other assessments. Conclusions: The rehabilitation program focused on real daily activities and demonstrated to improve patients' quality of life and caregivers' depression and caring burden through patient-caregiver interaction. Future enhanced follow-up systems are warranted.
RESUMEN
Pre-exposure prophylaxis with tixagevimab/cilgavimab was considered a useful strategy to protect immunocompromised patients from COVID-19 based on the phase 3 PROVENT trial conducted between November 2020 and March 2021. However, after late 2021, the dominant substrains of COVID-19 changed to Omicron substrains, which showed resistance to tixagevimab/cilgavimab. Therefore, it is important to re-evaluate the real-world efficacy of tixagevimab/cilgavimab for the prevention of COVID-19 in the Omicron era. To this end, we retrospectively evaluated the efficacy and safety of tixagevimab/cilgavimab prophylaxis for COVID-19 during the Omicron BA.5 wave in Japan. A total of 240 consecutive patients with hematologic malignancies received tixagevimab/cilgavimab at our institution from October 18, 2022, to January 31, 2023. Among them, the cumulative incidence of COVID-19 at 90 days was 6.4%. A total of 10/14 (71.4%) had mild infection, and 4/14 (28.5%) had severe infection. No patient died due to COVID-19. Adverse events consisted of deep vein thrombosis in 2 patients. Our analysis indicated that pre-exposure prophylaxis with tixagevimab/cilgavimab might have clinical effectiveness in reducing the severity of COVID-19 in Japanese HM patients, even in the Omicron BA.5 surge. It also suggested that tixagevimab/cilgavimab may be associated with cardiovascular complications.

Impaired function of the endoplasmic stress (ER) response causes numerous pathological conditions, including tissue fibrosis. In the present study, we aimed to determine the pathological role of ER stress response systems in myeloproliferative neoplasms (MPNs). We found increased expression of the chaperone protein glucose-regulated protein (GRP) 78, a central regulator of ER stress, in megakaryocytes from primary myelofibrosis or postessential thrombocythemia myelofibrosis patients. GRP78 was overexpressed in JAK2V617F-harboring cell lines; however, inhibitors of ER stress did not affect the expression levels of GRP78. In contrast, ruxolitinib, a well-known inhibitor of JAK2V617F, clearly blocked GRP78 expression in these cells through downregulation of transcription factor 4 (ATF4). Interestingly, GRP78 was secreted from HEL and SET-2 cells into culture media. Coculture of these cells with HS-5 cells, a human bone marrow stroma-derived cell line, induced enhanced expression of lysyl oxidase (LOX), which mediates cross-linking of collagen fibers and induces tissue fibrosis, in HS-5 cells. An anti-GRP78 neutralizing antibody abrogated LOX elevation; in contrast, recombinant GRP78 protein induced LOX protein expression in HS-5 cells. Our observations suggest that the oncogenic protein JAK2V617F induces overexpression and release of GRP78, which may induce a fibrotic phenotype in surrounding bone marrow stromal cells.

Hypokalemia is common in allogeneic hematopoietic stem cell transplantation (allo-HCT) patients and is associated with non-relapse mortality (NRM). Therefore, it is extremely important to replace potassium adequately. We evaluated the safety and efficacy of potassium replacement therapy by retrospectively analyzing the incidence and severity of hypokalemia in 75 patients who received allo-HCT at our institution. 75% of patients developed hypokalemia during the allo-HSCT, and 44% of patients had grade 3-4 levels of hypokalemia. NRM was significantly higher in patients with grade 3-4 hypokalemia than in patients without severe hypokalemia (one-year NRM: 30% vs 7%, p=0.008). Although 75% of the patients required potassium replacement that exceeded the range of potassium chloride solutions package inserts in Japan, we did not experience any adverse events associated with hyperkalemia. Our current observations suggested that the Japanese package insert for potassium solution injection should be revised for potassium needs.

BACKGROUND: Non-contrast T1 hypointense infarct cores (ICs) within infarcted myocardium detected using cardiac magnetic resonance imaging (CMR) T1 mapping may help assess the severity of left ventricular (LV) injury. However, because the relationship of ICs with chronic LV reverse remodeling (LVRR) is unknown, this study aimed to clarify it.MethodsâandâResults: We enrolled patients with reperfused AMI who underwent baseline CMR on day-7 post-primary percutaneous coronary intervention (n=109) and 12-month follow-up CMR (n=94). Correlations between ICs and chronic LVRR (end-systolic volume decrease ≥15% at 12-month follow-up from baseline CMR) were investigated. We detected 52 (47.7%) ICs on baseline CMR by non-contrast-T1 mapping. LVRR was found in 52.1% of patients with reperfused AMI at 12-month follow-up. Patients with ICs demonstrated higher peak creatine kinase levels, higher B-type natriuretic peptide levels at discharge, lower LV ejection fraction at discharge, and lower incidence of LVRR than those without ICs (26.5% vs. 73.3%, P<0.001) at follow-up. Multivariate logistic regression analysis showed that the presence of ICs was an independent and the strongest negative predictor for LVRR at 12-month follow-up (hazard ratio: 0.087, 95% confidence interval: 0.017-0.459, P=0.004). Peak creatine kinase levels, native T1 values at myocardial edema, and myocardial salvaged indices also correlated with ICs. CONCLUSIONS: ICs detected by non-contrast-T1 mapping with 3.0-T CMR were an independent negative predictor of LVRR in patients with reperfused AMI.

We analyzed the incidence of bone marrow fibrosis in 91 newly diagnosed Japanese multiple myeloma (MM) patients and evaluated the impact of fibrosis on clinical characteristics and therapeutic outcomes. Thirty-four (37%) patients had greater than grade 1 bone marrow fibrosis. The presence of bone marrow fibrosis did not affect laboratory data, the percentage of plasma cells in bone marrow or cytogenetic findings. It also had no significant effect on response to initial treatment, engraftment after autologous hematopoietic stem cell transplantation or overall survival. Interestingly, the incidence of extramedullary disease at diagnosis was significantly higher in patients with bone marrow fibrosis (p = 0.006). Analysis of biological characteristics of MM cells revealed that expression of CD49e, an alpha5/beta1 integrin, was downregulated in MM cells derived from patients with bone marrow fibrosis (p = 0.026). When seven of the original 34 patients were re-evaluated for fibrosis grading after treatment, five (71%) showed a reduction in fibrosis. Our present findings suggest that the presence of bone marrow fibrosis may predict development of extramedullary disease in MM.

AIMS: Heart failure (HF) prognosis has been reported similar in patients with preserved vs. reduced left ventricular ejection fraction (LVEF). This study compared the long-term prognosis of HF patients undergoing radiofrequency catheter ablation (RFCA) for atrial fibrillation (AF). METHODS AND RESULTS: Among 5010 patients undergoing RFCA in Kansai Plus AF registry, 656 patients (13.1%) with a documented history of HF were enrolled in the study before RFCA. The primary endpoint was a composite of all-cause death, HF hospitalization, and stroke or systemic embolism. Patients with reduced (<40%), mid-range (40-49%), and preserved (≥50%) LVEF were 98 (14.9%), 107 (16.3%), and 451 (68.8%) patients, respectively. The prevalence of ischaemic heart disease and cardiomyopathies was higher among patients with reduced as compared with preserved LVEF (27.6% vs. 10.0%, P < 0.05 and 36.7% vs. 15.3%, P < 0.05, respectively). The median follow-up period was 2.9 years. The 3-year cumulative risk for the primary endpoint was higher in patients with reduced LVEF (32.7%) compared to those with mid-range (11.7%) or preserved (11.6%) LVEF (P < 0.001). Reduced LVEF was the most significant independent risk factor for primary endpoint (hazard ratio, 2.83; 95% confidence interval 1.74-4.61, P < 0.001). The 3-year arrhythmia recurrence rate was similar among the groups (48.2%, 42.8%, and 47.3%, respectively, P = 0.75). CONCLUSION: This study raises hypothesis that patients with HFrEF and AF had approximately three times higher risk for a composite of all-cause death, HF hospitalization, and stroke or systemic embolism after AF ablation compared with patients with HFmrEF or HFpEF.

OBJECTIVE: This research was carried out to report the activity of the headquarters for disaster control at our hospital, and investigate the usefulness of obtaining information from Twitter when Typhoon Hagibis hit Izu Peninsula. METHODS: First, we recounted the activity of the headquarters for disaster control. We then collected information from Twitter from October 12-14, 2019, using the keyword Izunokuni.' We took into consideration the contents of Twitter user posts as well as the number of reactions ('retweets' and 'likes'). Twitter information was classified into photo (+) and (-) groups, depending on whether or not the post had a photo or video included. The number of reactions between the two groups was then analyzed. RESULTS: We counted 122 Twitter posts containing Hagibis-related information for Izunokuni City. The average number of both 'retweets' and 'likes' in the photo (+) group were significantly greater than those in the photo (-) group. All photos and videos depicted specific places in Izunokuni City and included actual footage of disaster scenes or local warning signs. CONCLUSION: Based on our experience at the headquarters for disaster control during Typhoon Hagibis, Twitter was considered to be a useful tool for obtaining local disaster information based on its timeliness, reality and specificity.

In recent years, the incidence of dental erosion caused by the ingestion of acidic foods and drinks, including sports drinks, has been increasing in Japan and elsewhere. Therefore, the problems associated with this injury can no longer be ignored in dental clinical practice. The ingestion of these foods and drinks is important from the viewpoint of overall health and disease prevention. For example, fermented foods, such as Japanese pickles, enhance the nutritional value of foodstuffs and promote the absorption of nutrients into the body, and sports drinks are useful for preventing heat stroke and dehydration. Therefore, eliminating these intakes is not a viable solution. In this paper, we outline the mechanism of dental erosion caused by acidic beverages and also describe the effectiveness of alkaline ionized water (AIW) at preventing acid erosion. Given the fact that the complete elimination of acidic beverage consumption is highly unlikely, remedies such as the use of alkaline ionized water (AIW) may be helpful.

Although a significant association between periodontal disease and atherosclerotic cardiovascular disease has been reported, their cause-to-effect relationship remains controversial. This randomized controlled clinical trial aimed to investigate the effect of advanced self-care on atherosclerotic cardiovascular disease-related vascular function markers flow-mediated brachial artery dilatation (FMD) and serum asymmetric dimethylarginine (ADMA) level in patients with early-stage periodontal disease. The study was designed as a parallel group, 3-month follow-up, open-label, randomized controlled trial. The control group received standard care for periodontal diseases, whereas the test group additionally applied disinfectant using a custom-fabricated prescription tray for advanced self-care twice a day. Overall, 110 patients provided data for FMD and serum ADMA level. No significant improvements in FMD were observed in the control (mean increase, -0.1%; 95% confidence interval [CI], -1.0-0.8; P = 0.805) or test (mean increase, -0.3%; 95% CI, -1.1-0.4; P = 0.398) group. No significant changes in serum ADMA levels were observed (mean reduction, 0.01 µmol/L; 95% CI, -0.00-0.02; P = 0.366 and mean reduction, 0.00 µmol/L; 95% CI, -0.01-0.01; P = 0.349, respectively). No significant between-group differences were found in FMD (mean difference, -0.2%; 95% CI, -1.4-0.9; p = 0.708) or serum ADMA levels (mean difference, 0.01 nmol/L; 95% CI, -0.00-0.03; p = 0.122). Significant improvements in the average probing pocket depth were observed in the control and test groups. The bleeding on probing score in the test group was significantly reduced, while that in the control group was reduced, although not significantly. Periodontal care for a 3-month duration did not provide better endothelial function although improvements of periodontal status in patients with early-stage periodontal diseases. This trial is registered in UMIN Clinical Trials Registry (www.umin.ac.jp/ctr/; ID: UMIN000023395).

BACKGROUND: The International Classification of Functioning, Disability, and Health (ICF) Generic-30 (Rehabilitation) Set is a tool used to assess the functioning of a clinical population in rehabilitation. The ICF Generic-30 consists of nine ICF categories from the component "body functions" and 21 from the component "activities and participation". This study aimed to develop a rating reference guide for the nine body function categories of the ICF Generic-30 Set using a predefined, structured process and to examine the interrater reliability of the ratings using the rating reference guide. METHODS: The development of the first version of the rating reference guide involved the following steps: (1) a trial of rating patients by several raters; (2) cognitive interviews with each rater to analyze the thought process involved in each rating; (3) the drafting of the rating reference guide by a multidisciplinary panel; and (4) a review by ICF specialists to confirm consistency with the ICF. Subsequently, we conducted a first field test to gain insight into the use of the guide in practice. The reference guide was modified based on the raters' feedback in the field test, and an inter-rater reliability test was conducted thereafter. Interrater agreement was evaluated using weighted kappa statistics with linear weights. RESULTS: The first version of the rating reference guide was successfully developed and tested. The weighted kappa coefficient in the field testing ranged from 0.25 to 0.92. The interrater reliability testing of the rating reference guide modified based on the field test results yielded an improved weighted kappa coefficient ranging from 0.53 to 0.78. Relative improvements in the weighted kappa coefficients were observed in seven out of the nine categories. Consequently, seven out of nine categories were found to have a weighted kappa coefficient of 0.61 or higher. CONCLUSIONS: In this study, we developed and modified a rating reference guide for the body function categories of the ICF Generic-30 Set. The interrater reliability test using the final version of the rating reference guide showed moderate to substantial interrater agreement, which encouraged the use of the ICF in rehabilitation practice.

Post-transplant lymphoproliferative disorder (PTLD) usually develops with systemic symptoms, such as fever, generalized lymphadenopathy, and elevation in the lactate dehydrogenase level. Here, we present the case of a 65-year-old female patient with PTLD localized to the colon; the patient only had mild diarrhea without systemic symptoms. She had myelodysplastic syndrome and was treated with cord blood transplantation (CBT). She had a past medical history of sigmoid colon cancer treated with colonosectomy and adjuvant chemotherapy. After CBT, she achieved complete remission and was discharged after 60 days. Further, 79 days after CBT, she presented with abdominal pain. Computed tomography scan revealed adhesive ileus. The abdominal pain was resolved in 1 day with conservative treatment, however, mild diarrhea persisted. Therefore, we performed colonoscopy and found multiple ulcerative lesions in the upper colon. A pathological examination revealed PTLD. Furthermore, elevation of EBV-DNA in the blood was also confirmed. There was no detectable lesion on positron emission tomography-computed tomography (PET-CT) outside the colon; thus, we diagnosed PTLD localized into the colon that was successfully treated with rituximab. Our present experience suggests that it might be important to perform endoscopy and monitoring of EBV-DNA for early detection of PTLD, especially localized in the gastrointestinal tract.

The 4-Fr catheter system is not recommended for invasive functional assessment of coronary artery stenosis, because it tends to distort the aortic waveform. This study aimed to identify the incidence of aortic waveform distortion and a feasible method for correct diagnosis of coronary artery stenosis with a 4-Fr catheter. We retrospectively investigated 178 lesions with intermediate coronary artery stenosis. Non-hyperemic distal coronary artery pressure (Pd) and aortic pressure (Pa) were measured with a 4-Fr diagnostic or 6-Fr guiding catheter before and after saline flush. The mean Pd/mean Pa (Pd/Pa) and instantaneous wave-free ratio (iFR) were calculated before and after flushing. We compared the effect of flushing on the changes in Pd/Pa and iFR between the 4-Fr diagnostic and 6-Fr guiding catheters. Using the 4-Fr diagnostic catheter, there was a significant decrease in incidence of aortic waveform distortion from 42.0% (47 lesions) before flushing to 1.8% (2 lesions) after flushing (p < 0.001); the incidence was only 3.0% before saline flush and decreased to 0% after saline flush when using the 6-Fr guiding catheter. The presence of aortic waveform distortion influenced the iFR when the 4-Fr system was used. Functional measurements with the 4-Fr diagnostic catheter require adequate saline flush to remove the influence of aortic waveform distortion.

OBJECTIVES: This study sought to determine whether therapists experience more accidents annually with increased clinical experience, and whether experiencing an accident in the first year of practice is associated with accidents in the second year of practice. METHODS: We categorized 642 therapists into five groups based on years of clinical experience (first, second, third, fourth, and 5-20 years; n=138, 112, 117, 58, and 217, respectively) and tallied the accidents they reported over an 8-year period. The difference between the five groups in the number of accidents per person per year was subjected to multiple comparisons testing using Kruskal-Wallis tests. RESULTS: Significant differences were revealed between the first year group and the 5-20 years group (p<0.01), between the second year group and the 5-20 years group (p<0.05), and between the third year group and the 5-20 years group (p<0.05). Specifically, participants in the 5-20 years group encountered fewer accidents than those in the other groups. Therapists who encountered an accident in their first year, compared with those who had not, had significantly more accidents in their second year. CONCLUSIONS: Therapists with 1-3 years of clinical experience are more likely to encounter an accident than therapists with >5 years of clinical experience. We conclude that young therapists who have experienced accidents are prone to future accidents. These findings inform the optimal allocation of educational resources to reduce the number of accidents encountered by therapists.
