ObjectiveTo determine the prevalence of potentially inappropriate medication (PIM) use at admission and discharge among hospitalised elderly patients and evaluate the association between PIMs at discharge and unplanned readmission in Japan.DesignA prospective observational study conducted by using electronic medical records.ParticipantsAll consecutive patients aged 65 years or older who were admitted to the internal medicine ward were included. Patients who were electively admitted for diagnostic procedures were excluded.Main outcome measuresThe primary outcome was 30-day unplanned readmissions. The secondary outcome was the prevalence of any PIM use at admission and discharge. PIMs were defined based on the Beers Criteria. The association between any PIM use at discharge and the primary outcome was evaluated by using logistic regression.ResultsSeven hundred thirty-nine eligible patients were included in this study. The median patient age was 82 years (IQR 74–88); 389 (52.6%) were women, and the median Charlson Comorbidity Index was 2 (IQR 0–3). The proportions of patients taking any PIMs at admission and discharge were 47.2% and 32.2%, respectively. Of all the patients, 39 (5.3%) were readmitted within 30 days after discharge for the index hospitalisation. The use of PIMs at discharge was not associated with an increased risk of 30-day readmission (OR 0.93; 95% CI 0.46 to 1.87). This result did not change after adjusting for patient age, sex, number of medications, duration of hospital stay and comorbidities (OR 0.78; 95% CI 0.36 to 1.66).ConclusionThe prevalence of any PIM use at discharge was high among hospitalised elderly patients in a Japanese hospital. Although the use of PIMs at discharge was not associated with an increased risk of unplanned readmission, given a lack of power of this study due to a low event rate, further studies investigating this association are needed.Trial registration numberUMIN000027189.

Abstract Background Homocysteine, folate, and vitamin B12 involved in 1-carbon metabolism are associated with cognitive disorders. We sought to investigate the relationships between these factors and delayed neurocognitive recovery (dNCR) after non-cardiac surgery. Methods This was a prospective observational study of patients (n = 175) who were ≥ 60 years of age undergoing non-cardiac surgery. Patients were evaluated preoperatively and for 1 week postoperatively by using neuropsychological tests and were divided into dNCR or non-dNCR groups according to a Z-score ≤ − 1.96 on at least two of the tests. The relationship between the occurrence of dNCR and preoperative levels of homocysteine, folate, and vitamin B12 was analyzed. Univariate and multivariable logistic regression analyses were conducted to identify factors associated with dNCR. Results Delayed neurocognitive recovery was observed in 36 of 175 patients (20.6%; 95% confidence interval [CI], 14.5–26.6%) 1 week postoperatively. Patients who developed dNCR had significantly higher median [interquartile range (IQR)] homocysteine concentrations (12.8 [10.9,14.4] μmol/L vs 10.6 [8.6,14.7] μmol/L; P = 0.02) and lower folate concentrations (5.3 [4.2,7.3] ng/mL vs 6.9 [5.3,9.5] ng/mL; P = 0.01) than those without dNCR. Compared to the lowest tertile, the highest homocysteine tertile predicted dNCR onset (odds ratio [OR], 3.9; 95% CI, 1. 3 to 11.6; P = 0.02), even after adjusting for age, sex, education, and baseline Mini Mental State Examination. Conclusions Elderly patients with high homocysteine levels who underwent general anesthesia for non-cardiac surgery have an increased risk of dNCR. This knowledge could potentially assist in the development of preventative and/or therapeutic measures. Trial registration NCT03084393 (https://www.clinicaltrials.gov)

OBJECTIVE Children with concussion frequently present to emergency departments (EDs). There is limited understanding of the differences in signs, symptoms, and epidemiology of concussion based on patient age. Here, the authors set out to assess the association between age and acute concussion presentations. METHODS The authors conducted a multicenter prospective observational study of head injuries at 10 EDs in Australia and New Zealand. They identified children aged 5 to < 18 years, presenting with a Glasgow Coma Scale score of 13–15, presenting < 24 hours postinjury, with no abnormalities on CT if performed, and one or more signs or symptoms of concussion. They extracted demographic, injury-related, and signs and symptoms information and stratified it by age group (5–8, 9–12, 13 to < 18 years). RESULTS Of 8857 children aged 5 to < 18 years, 4709 patients met the defined concussion criteria (5–8 years, n = 1546; 9–12 years, n = 1617; 13 to < 18 years, n = 1546). The mean age of the cohort was 10.9 years, and approximately 70% of the patients were male. Sport-related concussion accounted for 43.7% of concussions overall, increasing from 19.1% to 48.9% to 63.0% in the 5–8, 9–12, and 13 to < 18 years age groups. The most common acute symptoms postinjury were headache (64.6%), disorientation (36.2%), amnesia (30.0%), and vomiting (27.2%). Vomiting decreased with increasing age and was observed in 41.7% of the 5–8 years group, 24.7% of the 9–12 years group, and 15.4% of the 13 to < 18 years group, whereas reported loss of consciousness (LOC) increased with increasing age, occurring in 9.6% in the 5–8 years group, 21.0% in the 9–12 years group, 36.7% in the 13 to < 18 years group, and 22.4% in the entire study cohort. Headache, amnesia, and disorientation followed the latter trajectory. Symptom profiles were broadly similar between males and females. CONCLUSIONS Concussions presenting to EDs were more sports-related as age increased. Signs and symptoms differed markedly across age groups, with vomiting decreasing and headache, LOC, amnesia, and disorientation increasing with increasing age.

SummaryThe retrospective observational study surveys the relationship between development of inhibitors in the treatment of haemophilia patients and risk factors such as changing FVIII products. A total of 119 patients were included in this study, 198 changes of FVIII products were evaluated. Results: During the observation period of 12 months none of the patients developed an inhibitor, which was temporally associated with a change of FVIII products. A frequent change of FVIII products didn’t lead to an increase in inhibitor risk. The change between plasmatic and recombinant preparations could not be confirmed as a risk factor. Furthermore, no correlation between treatment regimens, severity, patient age and comorbidities of the patients could be found.

<b><i>Introduction:</i></b> In patients with atrial fibrillation (AF) at risk for stroke, dabigatran 150 mg twice a day (DE150) is superior to warfarin for stroke prevention. However, there is paucity of data with respect to bleeding risk at this dose in elderly patients (≥75 years). We aimed to evaluate the safety of DE150 in comparison to warfarin in a real-world population with AF and low bleeding risk (HAS-BLED score ≤2). <b><i>Methods:</i></b> In this prospective observational study, 754 consecutive patients with AF and HAS-BLED score ≤2 were included. We compared outcome of elderly patients (age ≥75 tears) to younger patients (age &#x3c;75 years). The primary end point was the combined incidence of all-cause mortality, stroke, systemic emboli, and major bleeding event during a mean follow-up of 1 year. <b><i>Results:</i></b> There were 230 (30%) elderly patients, 151 patients were treated with warfarin, and 79 were treated with DE150. Fifty-two patients experienced the primary endpoint during the 1-year follow-up. Among the elderly, at 1-year of follow-up, the cumulative event rate of the combined endpoint in the DE150 and warfarin was 8.9 and 15.9% respectively (<i>p</i> = 0.14). After adjustment for age and gender, patients who were treated with DE150 had a nonsignificant difference in the risk for the combined end point as patients treated with warfarin both among the elderly and among the younger population (HR 0.58, 95% C.I = 0.25–1.39 and HR = 1.12, 95% C.I 0.62–2.00, respectively [<i>p</i> for age-group-by-treatment interaction = 0.83). <b><i>Conclusions:</i></b> Our results suggest that Dabigatran 150 mg twice a day can be safely used among elderly AF patients with low bleeding risk.

Abstract Background This study aimed to explore predictive factors of time below target glucose range (TBR) ≥ 1% among patients’ characteristics and glycemic variability (GV) indices using continuous glucose monitoring data in elderly patients with type 2 diabetes. Methods We conducted a prospective observational study on 179 (71 female) Japanese outpatients with type 2 diabetes aged ≥ 65 years. The characteristics of the participants with TBR ≥ 1% were evaluated by multivariate logistic regression analysis. Receiver-operating characteristic (ROC) curve analyses of GV indices, comprising coefficient of variation (CV), standard deviation, and mean amplitude of glycemic excursions, were performed to identify the optimal index for the identification of patients with TBR ≥ 1%. Results In the multivariate logistic regression analysis, none of the clinical characteristics, including HbA1c and C-peptide index, were independent markers for TBR ≥ 1%, while all three GV indices showed significant associations with TBR ≥ 1%. Among the three GV indices, CV showed the best performance based on the area under the curve in the ROC curve analyses. Conclusions Among elderly patients with type 2 diabetes, CV reflected TBR ≥ 1% most appropriately among the GV indices examined. Trial registration UMIN-CTR: UMIN000029993.

Abstract Objective: We evaluate the association between the Dietary Inflammatory Index (DII) and kidney stones. Design: We performed a cross-sectional analysis using data from National Health and Nutrition Examination Survey. Dietary intake information was assessed using first 24-HR dietary recall interviews, and the Kidney Conditions was presented by questionnaire. The primary outcome was to investigate the association between DII and incidence of kidney stones, and the secondary outcome was to assess the association between DII and nephrolithiasis recurrence. Setting: The National Health and Nutrition Examination Survey (NHANES), 2007-2016. Participants: The study included 25984 NHANES participants, whose data on DII and kidney stones were available, of whom 2439 reported a history of kidney stones. Results: For the primary outcome, after fully multivariate adjustment, DII score is positively associated with the risk of kidney stones (OR = 1.07; 95% CI: [1.04–1.10]). Then, compared Q4 with Q1, a significant 38% increased likelihood of nephrolithiasis was observed. (OR=1.38; 95% CI: [1.19–1.60]). For the secondary outcome, the multivariate regression analysis showed that DII score is positively correlated with nephrolithiasis recurrence (OR=1.07; 95% CI: [1.00–1.15]). The results noted that higher DII scores (Q3 and Q4) are positively associated with a significant 48% and 61% increased risk of nephrolithiasis recurrence compared with the reference after fully multivariate adjustment. (OR=1.48; 95% CI: [1.07–2.05]; OR=1.61; 95% CI: [1.12–2.31]). Conclusions: Our findings revealed that increased intake of pro-inflammatory diet, as a higher DII score, is correlated with increased odds of kidney stones incidence and recurrence.

Background: The Multi-Ethnic Study of Atherosclerosis (MESA) is a large prospective epidemiologic study of the clinical factors that can predict transition from asymptomatic to symptomatic cardiovascular disease. Although prior studies have looked at ischemic stroke, they have not systematically examined the relationship between baseline ultrasound and inflammation measurements and subsequent primary stroke risk. Methods: The primary outcome is incident ischemic stroke during follow-up. The predictors are 9 ultrasound-derived measurements and 5 serum measurements related to inflammation. We fit Cox models to ischemic stroke and adjusted for patient age, hypertension, diabetes, total cholesterol, and smoking. Using DeLong’s method, we compared the AUC of the baseline adjusted model to the AUC of the model with predictor variables that were significant in the Cox models, to determine if they improved stroke prediction. Results: We included 6,095 patients with an average age of 61.9 years. The primary outcome of ischemic stroke was seen in 107 patients (1.8%) and the mean follow-up time was 7.7 years. In the Cox models, we found that small artery elasticity (SAE), carotid distensibility (CD), carotid stenosis (CS), and interleukin-6 (IL6) were associated with incident stroke. The AUC of the baseline model to predict stroke, which included patient age, hypertension, diabetes, total cholesterol, and smoking, was 0.745. When we added tertiles of SAE, CD, IL6 and categories of CS, the AUC improved to 0.765 (p=0.021 for difference). Conclusions: In a multiethnic cohort of patients without CVD at baseline, we found several ultrasound measurements and a serum marker of inflammation which predicted the occurrence of a primary ischemic stroke. Adding these basic ultrasound and serum measurements significantly improved the prediction of stroke, which could have implications for primary prevention efforts.

Objective Transoral surgery is becoming a preferred technique because it does not leave any scar after surgery. However, transoral surgery for a dermoid cyst of the oral cavity is not standardized yet, due to the anatomic complexity of this region. The aim of this study was to evaluate the safety and efficacy of a transoral dermoid cyst excision. Study Design Multicenter prospective observational study. Setting University hospital. Subjects and Methods This study was designed as a 4-year prospective multicenter evaluation of dermoid cyst excisions within the floor of mouth. Clinical outcomes and complications related to procedures were evaluated among patients. The primary outcome was the efficacy of the procedure, and the secondary outcome was cosmetic satisfaction of each procedure. Results Twenty-one patients underwent transoral dermoid cyst excisions, and 22 underwent transcervical excisions. In the transoral surgery group, the mean size of the dermoid cyst was 5.35 cm (95% CI, 4.79-5.91), and in the transcervical surgery group, it was 6.19 cm (95% CI, 5.67-6.71). There was no significant differences with respect to overall demographic characteristics between the groups. However, the duration of the operation was shorter with the transoral group than with the transcervical group ( P = .001), and cosmetic satisfaction was much better in the transoral group ( P < .001). Conclusion Transoral dermoid cyst excision is a potentially safe and effective method that can lead to easy and quick removal of an oral cavity dermoid cyst, with excellent cosmetic outcomes.
