Verifying the validity and reliability of the Japanese version of the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Scale

BackgroundPediatric patients, especially in the preverbal stage, cannot self-report intensity of pain therefore several validated observational tools, including the Face, Legs, Activity, Cry, Consolability (FLACC) Behavioral Scale, have been used as a benchmark to evaluate pediatric pain. Unfortunately, this scale is currently unavailable in Japanese, precluding its widespread use in Japanese hospitals.ObjectivesTo translate and verify the validity and reliability of the Japanese version of the FLACC Behavioral Scale.MethodBack-translation was first conducted by eight medical researchers, then an available sample of patients at the University of Tsukuba Pediatric Intensive Care Unit (from May 2017 to August 2017) was enrolled in a clinical study. Two researchers evaluated the validity of the translated FLACC Behavioral Scale by weighted kappa coefficient and intraclass correlation coefficients (ICC). Observational pain was simultaneously measured by the visual analog scale (VAS obs) and reliability was evaluated by correlation analysis.ResultThe original author approved the translation. For the clinical study, a total of 121 observations were obtained from 24 pediatric patients. Agreement between observers was highly correlated for each of the FLACC categories (Face: κ = 0.85, Leg: κ = 0.74, Activity: κ = 0.89, Cry: κ = 0.93, Consolability: κ = 0.93) as well as the total score (Total: κ = 0.95,). Correlation analysis demonstrated a good criterion validation between the FLACC scale and the VAS obs. (r = 0.96)ConclusionOur Japanese version of the FLACC Behavioral Scale shows high validity and reliability

IL-10 Inhibits Transforming Growth Factor-ß-Induction of Type I Collagen mRNA Expression via Both JNK and p38 Pathways in Human Lung Fibroblasts

Transforming growth factor-ß (TGF-ß) is a key factor for understanding the pathogenesis of fibrotic disorders such as idiopathic pulmonary fibrosis (IPF). We have demonstrated that interleukin-10 (IL-10) suppresses TGF-ß-induced expression of type I collagen (COL1) mRNA in a human lung fibroblast cell line (WI-38). However, the inhibitory mechanism has not yet been clearly elucidated. Thus, in the current study, we investigate the effects of IL-10 blockade of TGF-ß signaling which regulates COL1 mRNA expression. In WI-38 cells, IL-10 inhibits TGF-ß-mediated phosphorylation of both, c-Jun HN2-terminal kinase (JNK) and p38, but does not suppress TGF-ß- mediated phosphorylation of Smad2 or affect TGF-ß-upregulation of Smad7 mRNA expression. In addition, SP600125 and SB203580, specific inhibitors of JNK and p38, respectively, attenuate TGF-ß-induced COL1 mRNA expression in WI-38 cells. These results suggest that IL-10 inhibits TGF-ß-induced COL1 mRNA expression via both JNK and p38 pathways but not Smad pathways in WI-38 cells. This inhibitory mechanism may provide a novel insight into therapeutic strategies for fibrotic disorders such as IPF

Verifying the Japanese version of the Preschool Confusion Assessment Method for the ICU (psCAM‐ICU)

AimPediatric delirium has been well investigated and its prevalence is reported to be from 20% to 44%. For pediatric intensive care settings, several validated assessment tools for diagnosing delirium, including the Preschool Confusion Assessment Method for the Intensive Care Unit (psCAM‐ICU), are available in English. However, validated assessment tools for identifying pediatric delirium are unavailable in Japanese. Therefore, the aim of this study is to verify the Japanese translation of the psCAM‐ICU.MethodsWe enrolled patients at the Pediatric ICU at University of Tsukuba Hospital (Tsukuba, Japan) from May 2017 to February 2019. Enrollment criteria included patients aged 6 months to 5 years, and we excluded coma patients scoring under −4 on the Richmond Agitation–Sedation Scale or suffering from stroke. Pediatric patient delirium was simultaneously evaluated by three medical workers (pediatric intensivist and researchers). Psychiatrists then verified these findings against criteria of the Diagnostic and Statistical Manual of Mental Disorders – 5th Edition. We evaluated criterion validity (sensitivity and specificity) and reliability using Cohen\u27s κ coefficient.ResultsWe made a total of 56 independent assessments of 19 patients (42% female) with an average age of 18 (±15) weeks. Mechanical ventilation was used at least once in 73% of patients and the positive rate of delirium was 54% in total observation. Overall, the psCAM‐ICU showed high sensitivity, specificity (sensitivity, 0.90 [95% confidence interval [CI], 0.80–0.94]; specificity, 0.93 [95% CI, 0.83–0.97]), and high reliability within the researcher assessments (κ = 0.92; 95% CI, 0.82–1.0).ConclusionWe verified the psCAM‐ICU and it shows high validity and reliability

Association between fluid overload and delirium/coma in mechanically ventilated patients

AimSeveral studies have shown an association between fluid overload (FO) and mortality or duration of mechanical ventilation in critically ill patients. However, the association between FO and delirium duration remains unclear.MethodsThis retrospective observational cohort study was undertaken at University of Tsukuba Hospital (Tsukuba, Japan) from April 2015 to March 2017. Mechanically ventilated patients who stayed in the intensive care unit for more than 7 days were eligible for inclusion. Univariate analysis was carried out with the Mann–Whitney U-test for continuous variables and Fisher’s exact test for categorical variables. A multivariate proportional odds logistic regression model was used to evaluate the association between FO and delirium/coma days (DCDs) during the 7-day study period.ResultsA total of 118 patients were included and divided into FO and non-FO groups. Fluid overload occurred in 40% of patients. The FO group had a higher APACHE II score than the non-FO group (19 [16–26] versus 23 [20–29], P = 0.017). Cumulative fluid balance at day 3 was higher in the FO group (3,238 [281–6,530] versus 7,886 [4,106–10,631], P < 0.001). Delirium days within 7 days was longer in the FO group (1 [0–3] versus 2 [1–3], P = 0.048) and DCDs was longer in the FO group (4 [1–5] versus 6 [3–7], P = 0.002). After adjusting for covariates, there were significant associations between FO and DCDs (odds ratio, 2.16; 95% confidence interval, 1.05–4.47).ConclusionsOur findings suggest that FO is associated with increased DCDs in mechanically ventilated patients

Association between intensive care unit delirium and delusional memory after critical care in mechanically ventilated patients

AimTo determine the relationship between the delirium of patients with mechanical ventilation during intensive care unit (ICU) stay and delusional memory after ICU discharge.DesignProspective cohort study.MethodsDelirium in adult patients who received mechanical ventilation for more than 24 hr was assessed twice daily using the Confusion Assessment Method for the ICU. Delusional memories were evaluated using the ICU Memory Tool 5–10 days after ICU discharge. The associations between the presence of delirium during the ICU stay and delusional memories were evaluated.ResultsOf 60 enrolled patients, 62% had delirium during their ICU stay, and 68% experienced delusional memories 5–10 days after discharge. Delirium during ICU stay was an independent factor to experience delusional memories following discharge. Preventing delirium during ICU stay might reduce delusional memory. We recommend that patients with delirium during their ICU stay should be carefully followed up after discharge from the ICU

PERSonality, Ehical, and PROfessional quality of life in Pediatric/Adult Intensive Nurses study: PERSEPRO PAIN study

BackgroundThe World Health Organization included burnout syndrome criteria that reduce both professional quality of life and work satisfaction in its 11th Revision of the International Classification of Diseases in 2019 while nursing bodies have issued action calls to prevent burnout syndrome. Despite this, the effect of social factors, personality traits and cross-interaction on professional quality of life is still unclear.AimTo reveal the association between ethical climate, personal trait and professional quality of life.MethodAn online survey of registered nurses working in adult, pediatric or both ICUs. We used the ten-item personality measure based on The Big Five theory and Type-D personality Scale-14 then measured the ethical climate with the Hospital Ethical Climate Survey and the professional domains of burnout syndrome, secondary traumatic stress and compassion satisfaction by the Professional Quality of Life Scale Version 5 simultaneously. Multivariate analysis confirmed the triangular association of hospital ethical climate, personality traits and professional quality of life.ResultWe enrolled 310 participants from September 2019 to February 2020. Mean age was 33.1 years (± 5.9) and about 70% were female. In the multivariate analysis, neuroticism (p = 0.03, p = 0.01) and Type D personality (both of p<0.01) were associated with burnout syndrome and secondary traumatic stress while agreeableness (p<0.01) was associated with secondary traumatic stress. Conversely, extraversion (p = 0.01), agreeableness (p<0.01) and openness (p<0.01) were associated with compassion satisfaction. We also observed interactions between hospital ethical climate and conscientiousness (p = 0.01) for burnout syndrome and secondary traumatic stress. Neuroticism was related to (p<0.01) BOS and compassion satisfaction while Type D personality (p<0.01) correlated with burnout syndrome and secondary traumatic stress.ConclusionHospital ethical climate strongly affects professional quality of life in nurses with specific personality traits. Therefore, it is important to maintain an ethical hospital climate, considering individual personalities to prevent burnout syndrome

Down Syndrome Reduces the Sedative Effect of Midazolam in Pediatric Cardiovascular Surgical Patients

Down syndrome (DS) is frequently comorbid with congenital heart disease and has recently been shown to reduce the sedative effect of benzodiazepine (BDZ)-class anesthesia but this effect in a clinical setting has not been studied. Therefore, this study compared midazolam sedation after heart surgery in DS and normal children. We retrospectively reviewed patient records in our pediatric intensive care unit (PICU) of pediatric cardiovascular operations between March 2015 and March 2018. We selected five days of continuous post-operative data just after termination of muscle relaxants. Midazolam sedation was estimated by Bayesian inference for generalized linear mixed models. We enrolled 104 patients (average age 26 weeks) of which 16 (15%) had DS. DS patients had a high probability of receiving a higher midazolam dosage and dexmedetomidine dosage over the study period (probability = 0.99, probability = 0.97) while depth of sedation was not different in DS patients (probability = 0.35). Multi regression modeling included severity scores and demographic data showed DS decreases midazolam sedation compared with controls (posterior OR = 1.32, 95% CrI = 1.01–1.75). In conclusion, midazolam dosages should be carefully adjusted as DS significantly decreases midazolam sedative effect in pediatric heart surgery patients

Development of the Japanese version of the State Behavioral Scale for critically ill children

AimsThe State Behavioral Scale (SBS) was developed to assess sedation states, including agitation, in pediatric patients on mechanical ventilation. The purpose of this study was to determine the reliability and validity of a back-translated Japanese version of the SBS.MethodsTranslation was done by the back-translation method followed by a prospective study in a Japanese intensive care unit. For reliability, a nurse/researcher pair evaluated SBS along eight dimensions (respiratory drive, response to ventilation, coughing, best response to stimulation, attentiveness to care provider, tolerance to care, consolability, and movement after consoled). For validity, SBS scores were compared to the Richmond Agitation–Sedation Scale and a visual analog scale (VAS).ResultsThe original author approved the back-translated SBS. Thirty-one patients aged 0 weeks to 8 years were evaluated from 59 total critical pediatric patient encounters. The researcher and nurse SBS scores demonstrated excellent inter-rater reliability (weighted κ = 0.96, 95% CI 0.92–0.99). In addition, there was a very strong correlation between the researcher and nurse VAS scores (ρ = 0.80, P < 0.001). Weighted kappa coefficients for the eight dimensions ranged from 0.71 (95% confidence interval, 0.55–0.88; consolability) to 0.89 (95% confidence interval, 0.80–0.98; best response to stimulation). In validity testing, nurse SBS and nurse VAS scores were strongly correlated (ρ = 0.80, P < 0.001) with the researcher SBS and researcher Richmond Agitation–Sedation Scale scores (ρ = 0.91, P < 0.001).ConclusionThis study suggests that our Japanese version of the SBS is valid and reliable for evaluating sedation for critically ill children.Original Articl

Type D personality is a predictor of prolonged acute brain dysfunction (delirium/coma) after cardiovascular surgery

BackgroundPrevious studies have shown a relationship between delirium and depressive symptoms after cardiac surgery with distress personalities linking to negative surgical outcomes. The aim of the present study is to further investigate the association between patients with Type D (distressed) personality with regards to delirium after cardiac surgery.MethodsWe conducted a consecutive-sample observational cohort pilot study with an estimated 142 patients needed. Enrollment criteria included patients aged ≥18 years who were undergoing planned cardiovascular, thoracic and abdominal artery surgery between October 2015 to August 2016 at the University of Tsukuba Hospital, Japan. All patients were screened by Type-D Personality Scale-14 (DS14) as well as the Hospital Anxiety and Depression Scale (HADS) the day before surgery. Following surgery, daily data was collected during recovery and included severity of organ dysfunction, sedative/analgesic exposure and other relevant information. We then evaluated the association between Type D personality and delirium/coma days (DCDs) during the 7-day study period. We applied regression and mediation modeling for this study.ResultsA total of 142 patients were enrolled in the present study and the total prevalence of delirium was found to be 34% and 26% of the patients were Type D. Non-Type D personality patients experienced an average of 1.3 DCDs during the week after surgery while Type D patients experienced 2.1 days over the week after surgery. Multivariate analysis showed that Type D personality was significantly associated with increased DCDs (OR:2.8, 95%CI:1.3–6.1) after adjustment for depressive symptoms and clinical variables. Additionally, there was a significant Type D x depression interaction effect (OR:1.7, 95% CI:1.2–2.2), and depressive symptoms were associated with DCDs in Type D patients, but not in non-Type D patients. Mediation modeling showed that depressive symptoms partially mediated the association of Type D personality with DCDs (Aroian test =0.04).ConclusionsType D personality is a prognostic predictor for prolonged acute brain dysfunction (delirium/coma) in cardiovascular patients independent from depressive symptoms and Type D personality-associated depressive symptoms increase the magnitude of acute brain dysfunction.Research articl
