Clinical Outcomes of Preserving Bronchial Arteries During Radical Esophagectomy: A Propensity-Score Matched Analysis.

BACKGROUND: Postoperative pneumonia is a common and major cause of mortality after radical esophagectomy. Intraoperative preservation of the bronchial arteries is often aimed at avoiding tracheobronchial ischemia; however, it is unknown whether this contributes to a reduction in postoperative pneumonia. PATIENTS AND METHODS: We enrolled 348 consecutive patients who underwent radical esophagectomy for esophageal cancer at Toranomon Hospital from January 2011 to July 2018. We classified patients into a bronchial artery-resected (BA-R) group (n = 93) and a bronchial artery-preserved (BA-P) group (n = 255) and compared the incidence of postoperative pneumonia between the two groups. A propensity score-matching analysis for bronchial artery preservation versus resection was performed. RESULTS: Overall, 182 patients were matched. Univariate analysis of the propensity score-matched groups showed that Brinkman index ≥ 400, vital capacity (%VC) < 80%, and bronchial artery resection were associated with the development of postoperative pneumonia. Multivariate analysis revealed three significant factors associated with postoperative pneumonia: Brinkman index ≥ 400 [p = 0.006, odds ratio (HR) 3.302, 95% confidence interval (95% CI) 1.399-7.790], %VC < 80% (p = 0.034, HR 6.365, 95% CI 1.151-35.205), and bronchial artery resection (p = 0.034, HR 2.131, 95% CI 1.060-4.282). The incidence of postoperative complications (CD grade III) was higher in the BA-R group (BA-R 42.8% versus BA-P 27.5%, p = 0.030). There was no significant difference in overall survival between the two groups at 5 years (BA-R 63.1% versus BA-P 72.1%, p = 0.130). CONCLUSION: Preserving the bronchial artery is associated with a decreased incidence of postoperative pneumonia.

Anti-inflammatory effect of covalent PPARγ ligands that have a hybrid structure of GW9662 and a food-derived cinnamic acid derivative.

Peroxisome proliferator-activated receptor γ (PPARγ) belongs to nuclear receptor superfamily and is involved in inflammatory process. Previously, we synthesized the ligands of PPARγ which possess the hybrid structure of a food-derived cinnamic acid derivative (CA) and GW9662, an irreversible PPARγ antagonist. These ligands activate the transcription of PPARγ through the covalent bond formation with the Cys285 residue of PPARγ, whereas their anti-inflammatory effect has not been examined yet. Here, we show the anti-inflammatory effect of the covalent PPARγ ligands in RAW264 cells, murine macrophage-like cells. GW9662 suppressed the production of nitric oxide (NO) stimulated by lipopolysaccharide and exerted a synergistic effect in combination with CA. The compounds bearing their hybrid structure dramatically inhibited NO production and transcription of proinflammatory cytokines. A comparison study suggested that 2-chloro-5-nitrobenzoyl group of the ligands is important for anti-inflammation. Furthermore, we synthesized an alkyne-tagged analogue which become an activity-based probe for future mechanistic study.

Longitudinal Association Between Social Isolation and COVID-19 Vaccine Uptake in Japanese Older Citizen: an Observational Study.

BACKGROUND: Social isolation is associated with decreased intent to receive vaccination against coronavirus disease 2019 (COVID-19); however, its association with COVID-19 vaccine uptake is unknown. OBJECTIVE: The present study aimed to determine the association between social isolation and subsequent COVID-19 vaccination using the data from a representative Japanese sample. DESIGN: Longitudinal observational study. PARTICIPANTS: Japanese citizens aged ≥ 65 years who participated in the Quality of Life in COVID-19 Era (QoLCoVE) study which began in March 2020. MAIN MEASURES: Social isolation was assessed in March 2020 using the abbreviated Lubben Social Network Scale, with a score of ≤ 11 indicating social isolation. To evaluate the relationship between social isolation at the baseline and COVID-19 vaccine uptake (including reservation for vaccine administration) between August and September 2021, we estimated adjusted risk ratios with 95% CIs using modified Poisson regression with adjustment for potential confounders. KEY RESULTS: A total of 921 participants met the inclusion criteria in the initial survey, of whom 720 (78.2%) completed the follow-up survey. Median age was 70 years (interquartile range: 66-72), and 329 (45.7%) participants were male. Twenty-one (16.5%) of 127 socially isolated participants, and 48 (8.1%) of 593 non-socially isolated participants did not receive the COVID-19 vaccine. Socially isolated participants were less likely to take COVID-19 vaccine than non-socially isolated participants (adjusted risk ratio 1.98, 95% CI: 1.18-3.32). CONCLUSIONS: Social isolation is associated with reduced COVID-19 vaccine uptake among older adults. To further promote COVID-19 vaccination in the older population, support for social isolation might be necessary.

App-based interventions for the prevention of postpartum depression: a systematic review and meta-analysis.

BACKGROUND: This study explored whether psychosocial intervention applications (apps) are effective in preventing postpartum depression. METHODS: We conducted an initial article search on 26 March 2020, and the updated search on 17 March 2023 on the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE via Ovid, Scopus, PsycINFO, CINAHL, and ProQuest Dissertations & Theses A&I. Furthermore, we searched the International Clinical Trials Platform Search Portal (ICTRP), and Clinical Trials. RESULTS: We identified 2515 references, and sixteen studies were ultimately included in this review. We conducted a meta-analysis of two studies on the onset of postpartum depression. There were no significant differences between the intervention and control groups (RR 0.80; 95% CI 0.62 to 1.04; P = 0.570). We performed a meta-analysis of the Edinburgh Postnatal Depression Scale (EPDS). The intervention group had significantly lower EPDS scores than the control group (mean difference -0.96; 95% CI -1.44 to -0.48; P < 0.001, I2 = 82%, Chi2 = 62.75, P < 0.001; high heterogeneity). CONCLUSION: This study presents the results of current RCTs on interventions with apps, including an app with an automated psychosocial component for preventing postpartum depression that has been conducted. These apps improved the EPDS score; furthermore, they may prevent postpartum depression.

Prehospital shock index predicts 24-h mortality in trauma patients with a normal shock index upon emergency department arrival.

BACKGROUND: The shock index (heart rate divided by systolic blood pressure) of trauma patients upon emergency department arrival predicts blood loss and death. However, some patients with normal shock indices (0.4 < shock index <0.9) upon emergency department arrival also have poor prognoses. This study aimed to determine whether abnormal prehospital shock indices in trauma patients with normal shock indices upon emergency department arrival were predictors of a high risk of mortality. METHODS: We conducted a retrospective cohort study of emergency department-admitted trauma patients from 2004 to 2017. The study included 89,495 consecutive trauma patients aged ≥16 years, with Abbreviated Injury Scale score of ≥3, who were transported to the emergency department directly from the field and had a normal shock index upon emergency department arrival. According to the prehospital shock index scores, the patients were categorized into low shock index (≤ 0.4), normal shock index, and high shock index (≥0.9) groups. Odds ratios and 95% confidence intervals were calculated using logistic regression analysis. RESULTS: The 89,495 patients had a median age of 64 (interquartile range: 43-79) years, and 55,484 (62.0%) of the patients were male. There were 1350 (1.5%) 24-h deaths in total; 176/4263 (4.1%), 1017/78,901 (1.3%), and 157/6331 (2.5%) patients were in the low, normal, and high prehospital shock index groups, respectively. The adjusted odds ratios for 24-h mortality compared with the normal shock index group were 1.63 (95% confidence interval: 1.34-1.99) in the low shock index group and 1.62 (95% confidence interval: 1.31-1.99) in the high shock index group. CONCLUSION: Trauma patients with abnormal prehospital shock indices but normal shock indices upon emergency department arrival are at a higher risk of 24-h mortality. Identifying these indices could improve triage and targeted care for patients.

Trends in Prescribing Antipsychotics for Children and Adolescents in Japan: A Descriptive Epidemiological Study Using a Large-Scale Pharmacy Dataset.

Little is known about antipsychotic prescription patterns among children and adolescents in Japan, particularly in outpatient settings. We investigated the prevalence and trends of antipsychotic prescription for outpatients aged ≤ 17 years receiving a first antipsychotic prescription from 2006 to 2012 based on a large-scale dispensation dataset. Measurements included age, sex, department of diagnosis and treatment, type of prescription (monotherapy or polytherapy), antipsychotic dosage, and concomitant psychotropic drugs. Of the 10,511 patients, 65.1% were aged 13-17 years, and 52.9% were males. Second-generation antipsychotic monotherapy prescriptions increased from 53.8% in 2006 to 78.3% in 2012. Risperidone was the most frequently prescribed antipsychotic, followed by aripiprazole and olanzapine. Approximately 25.0% of patients were prescribed an initial dose less than recommended. Second-generation antipsychotic monotherapy is currently the most frequent prescription pattern among outpatients aged ≤ 17 years receiving an initial antipsychotic prescription.

Mood Stabilizers and Antipsychotics for Acute Mania: Systematic Review and Meta-Analysis of Augmentation Therapy vs Monotherapy From the Perspective of Time to the Onset of Treatment Effects.

BACKGROUND: Existing meta-analytic evidence on bipolar mania treatment has revealed that augmentation therapy (AUG) with antipsychotics and mood stabilizers is more effective than monotherapy. However, the speed of the onset of treatment effects and subsequent changes in risk/benefit are unclear. METHODS: We searched the Cochrane CENTRAL, MEDLINE, and EMBASE databases until January 2021. Our primary outcomes were response and tolerability. We set 3 time points: 1, 3, and 6 weeks after randomization. RESULTS: Seventeen studies compared AUG therapy and MS monotherapy (comparison 1), and 8 studies compared AUG therapy and antipsychotics monotherapy (comparison 2). In comparison 1, AUG therapy resulted in significantly more responses than monotherapy, with an odds ratio of 1.45 (95% confidence interval [CI]: 1.17 to 1.80) at 3 weeks and 1.59 (95% CI: 1.28 to 1.99) at 6 weeks. Significant improvement was observed in the first week with a standardized mean difference of -0.25 (95% CI: -0.38 to -0.12). In comparison 2, AUG therapy was significantly more effective than monotherapy, with an odds ratio of 1.73 (95% CI: 1.25 to 2.40) at 3 weeks and 1.74 (95% CI: 1.11 to 2.73) at 6 weeks. Significant improvement was observed in the first week with an standardized mean difference of -0.23 (95% CI: -0.39 to -0.07). Regarding tolerability, there was no significant difference between AUG therapy and monotherapy at 3 and 6 weeks in both comparisons. CONCLUSIONS: Early AUG therapy should be considered, as it has shown efficacy from weeks 1 to 6, although attention to side effects is necessary for acute mania treatment.

Early corticosteroid dose tapering in patients with acute exacerbation of idiopathic pulmonary fibrosis.

BACKGROUND: Although corticosteroid therapy with dose tapering is the most commonly used treatment for acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF), there is no consensus on the tapering regimen. This study aimed to investigate the association between early corticosteroid dose tapering and in-hospital mortality in patients with AE-IPF. METHODS: In this retrospective cohort study, we analyzed the data of a cohort from eight Japanese tertiary care hospitals and routinely collected administrative data from a cohort from 185 Japanese hospitals. Patients with AE-IPF were classified into the early and non-early tapering groups depending on whether the maintenance dose of corticosteroids was reduced within two weeks of admission. Propensity score analysis with inverse probability weighting (IPW) was performed to estimate the effect of early corticosteroid dose tapering. RESULTS: The multi-center cohort included 153 eligible patients, of whom 47 (31%) died, whereas the administrative cohort included 229 patients, of whom 51 (22%) died. Patients with early tapering tended to have a better prognosis than those without it (unadjusted hazard ratio [95% confidence interval] 0.41 [0.22-0.76] and 0.65 [0.36-1.18] in the multi-center and administrative cohorts, respectively). After IPW, the early tapering group had a better prognosis than the non-early tapering group (IPW-adjusted hazard ratio [95% confidence interval] 0.37 [0.14-0.99] and 0.27 [0.094-0.83] in the multi-center and administrative cohorts, respectively). CONCLUSION: Early corticosteroid dose tapering was associated with a favorable prognosis in patients with AE-IPF. Further studies are warranted to confirm the effects of early corticosteroid dose tapering in patients with AE-IPF.

Identification of Preoperative Fat-Free Mass Index for the Prognosis of Curatively Resected Esophageal Cancer.

BACKGROUND: The progressive, systemic depletion of muscle mass is a poor prognostic factor for various types of cancers. However, the assessment of body composition for patients with esophagectomy remains unclear. Therefore, we evaluated the significance of the fat-free mass index (FFMI) and estimated the appropriate cutoff value. METHODS: We compiled clinicopathological characteristics of patients who underwent curative operation for esophageal cancer between October 2013 and March 2018 at Toranomon Hospital and reviewed them until December 2020. We analyzed the short- and long-term outcomes, compared to conventional nutritional factors, and calculated the area under the receiver operating characteristic (ROC) curve. RESULTS: A total of 200 patients were eligible for inclusion. FFMI was ineffective in predicting postoperative complications, with no correlation with other nutritional biomarkers. Preoperative low FFMI led to poor overall survival (OS), and the lower cutoff values based on the time-dependent ROC analysis were 14.4 and 16.8 kg/m2 in women and men, respectively. Multivariate analysis for OS revealed that low FFMI (p = 0.010, HR 2.437, 95% CI 1.234-4.815) and clinical stage (p = 0.010, HR 4.781, 95% CI 1.447-15.796) were independent prognostic factors. The 3-year survival rates were 68.9% in low FFMI and 88.6% in normal FFMI. CONCLUSIONS: The low FFMI was not predictive of postoperative complications but an independent prognostic factor in esophageal cancer with curative resection, having no correlation with other biomarkers. Our cutoff FFMI values could be useful in selecting the target for muscle improvement programs.

Alcohol abuse as a potential risk factor of solitary death among people living alone: a cross-sectional study in Kyoto, Japan.

BACKGROUND: Solitary death is an emerging public health problem in developed countries. Alcohol abuse is associated with social isolation and excess mortality. However, data on the association between alcohol abuse and solitary death are limited. Our purposes were to assess whether alcohol abuse is associated with a long interval from death to discovery among people living alone. METHODS: This is a cross-sectional study using the data on subjects from the largest forensic database in Kyoto, Japan, from February 2012 to December 2015. Solitary death was defined as a phenomenon of dying alone at home and remaining undiscovered for more than 1 week. All the subjects who lived alone and aged over 18 at the time of death were included in the study. The presence of alcohol abuse was identified via an investigation during home visits. Proportional ratios were calculated using a fitted logit model to evaluate the association of alcohol abuse on solitary death after adjusting for possible confounders. RESULTS: A total of 235 subjects were included in the analysis. The mean age (standard deviation) of subjects at the time of death was 63.4 (15.1) years, and approximately 61.8% and 38.9% of subjects in the alcohol and non-alcohol abuse groups, respectively, experienced solitary death. Multivariable analyses revealed that alcohol abuse was associated with solitary death (adjusted proportion ratio: 1.50; 95% confidence interval: 1.12-2.00). CONCLUSIONS: The findings of this study could help identify individuals at higher risk of solitary death. Moreover, calling the attention of people with alcohol abuse may be beneficial to prevent solitary death.

Importance of long-term surveillance after curative esophagectomy for esophageal squamous cell carcinoma.

BACKGROUND: The long-term outcomes after esophagectomy for esophageal cancer remain uncertain and the optimal surveillance strategy after curative surgery remains controversial. METHODS: In this study, the clinicopathological characteristics of patients who underwent curative thoracic esophagectomy between 1991 and 2015 at Toranomon Hospital were retrospectively analyzed and reviewed until December 2020. We evaluated the accumulated data regarding the pattern and rates of recurrence and second malignancy. RESULTS: A total of 1054 patients were eligible for inclusion in the study. Of these, 97% were followed up for 5 years, and the outcomes after 25 years could be determined in 65.5%. Recurrence was diagnosed in 318 patients (30.2%), and the most common pattern was lymph node metastasis (n = 168, 52.8%). Recurrence was diagnosed within 1 year in 174 patients (54.7%) and within 3 years in 289 (90.9%). Second malignancy possibly occurred through the entire study period after esophagectomy even in early-stage cancer, keeping 2%-5% of the incidental risk. There was no significant difference in the prognosis between 3-year survivors with and without a second malignancy. CONCLUSIONS: Most recurrences after resection of esophageal cancer occurred within 3 years regardless of disease stage. However, these patients have an ongoing risk of developing a second malignancy after esophagectomy. Further consideration is required regarding the efficacy of long-term surveillance.

Clinical significance of initial treatment for peritoneal lavage cytology-positive gastric cancer: outcomes according to treatment strategy.

BACKGROUND: Although patients with positive lavage cytology (CY1) are classified as having stage IV disease, long-term survival without other unresectable factors (P0CY1) has been reported. Conversion gastrectomy in patients with a change in cytology status after induction chemotherapy might improve survival, but appropriate treatment remains controversial. Here, we reviewed our experience in treating CY1 gastric cancer to evaluate the best treatment strategy. METHODS: Clinical and pathological findings of patients with a diagnosis of P0CY1 gastric cancer at Toranomon Hospital between February 2006 and April 2019 were retrospectively analyzed. Patients were classified into two groups according to initial treatment: a surgery-first group and a chemotherapy-first group. In addition, the patients were categorized into subgroups based on the subsequent treatment pattern. The surgery-first group was divided into two subgroups: adjuvant chemotherapy and palliative gastrectomy only. The chemotherapy-first group was divided into three subgroups with the subsequent treatment pattern depending on the response to chemotherapy: conversion gastrectomy, palliative gastrectomy after induction therapy, and palliative chemotherapy. RESULTS: In total, 38 patients were eligible for inclusion in this study. After initial assessment of cytology status, 21 patients underwent gastrectomy as initial treatment (surgery first) and 17 received induction chemotherapy (chemotherapy first). Ten patients underwent surgery first with adjuvant chemotherapy, 11 underwent palliative gastrectomy alone, 5 underwent conversion surgery, 5 with CY1 disease after induction chemotherapy underwent palliative gastrectomy, and 7 received palliative chemotherapy only. The 3-year survival rate was 23.4% (median survival, 17.7 months) in the surgery-first group and 27.3% (median survival, 19.7 months) in the chemotherapy-first group. The 3-year survival rate was 75% for conversion gastrectomy, 16.7% for palliative chemotherapy, and 0% for palliative gastrectomy after induction chemotherapy. CONCLUSIONS: There was no significant difference in outcome according to whether surgery or chemotherapy was performed first. The prognosis of conversion surgery with curative resection was better than that of the other types of treatment. However, the outlook after induction chemotherapy was poor. Patients with advanced gastric cancer should be treated cautiously until more effective treatment options become available.

Unguided Computer-Assisted Self-Help Interventions Without Human Contact in Patients With Obsessive-Compulsive Disorder: Systematic Review and Meta-analysis.

BACKGROUND: Computer-assisted treatment may reduce therapist contact and costs and promote client participation. This meta-analysis examined the efficacy and acceptability of an unguided computer-assisted therapy in patients with obsessive-compulsive disorder (OCD) compared with a waiting list or attention placebo. OBJECTIVE: This study aimed to evaluate the effectiveness and adherence of computer-assisted self-help treatment without human contact in patients with OCD using a systematic review and meta-analysis approach. METHODS: Randomized controlled trials with participants primarily diagnosed with OCD by health professionals with clinically significant OCD symptoms as measured with validated scales were included. The interventions included self-help treatment through the internet, computers, and smartphones. We excluded interventions that used human contact. We conducted a search on PubMed, Cochrane Central Register of Controlled Trials, EMBASE, World Health Organization International Clinical Trials Registry Platform, and ClinicalTrials.gov, as well as the reference lists of the included studies. The risk of bias was evaluated using version 2 of the Cochrane risk-of-bias tool for randomized trials. We calculated the standardized mean differences for continuous outcomes and risk ratios for dichotomous outcomes. The primary outcomes were short-term improvement of OCD symptoms measured by validated scales and dropout for any reason. RESULTS: We included 11 randomized controlled trials with a total of 983 participants. The results indicated that unguided computer-assisted self-help therapy was significantly more effective than a waiting list or psychological placebo (standard mean difference -0.47, 95% CI -0.73 to -0.22). Unguided computer-assisted self-help therapy had more dropouts for any reason than waiting list or psychological placebo (risk ratio 1.98, 95% CI 1.21 to 3.23). However, the quality of evidence was very low because of the risk of bias and inconsistent results among the included studies. The subgroup analysis showed that exposure response and prevention and an intervention duration of more than 4 weeks strengthen the efficacy without worsening acceptability. Only a few studies have examined the interaction between participants and systems, and no study has used gamification. Most researchers only used text-based interventions, and no study has used a mobile device. The overall risk of bias of the included studies was high and the heterogeneity of results was moderate to considerable. CONCLUSIONS: Unguided computer-assisted self-help therapy for OCD is effective compared with waiting lists or psychological placebo. An exposure response and prevention component and intervention duration of more than 4 weeks may strengthen the efficacy without worsening the acceptability of the therapy.

Adequate period of surveillance in each stage for curatively resected gastric cancer: analyzing the time and rates of recurrence.

BACKGROUND: Surveillance after curative surgery for gastric cancer is conventionally performed for 5 years. However, the appropriate follow-up period remains controversial. METHODS: This study retrospectively compiled a clinicopathological database of patients who underwent curative gastrectomy between 1975 and 2010 at Toranomon Hospital and were reviewed until March 2020. Analyzing the follow-up rate and recurrence rate for each stage in each postoperative year, we set each follow-up endpoint when the subsequent recurrence rate fell below 1%. RESULTS: A total of 5235 patients were eligible for inclusion in the study. The rate of patients followed up for 5 years was 90.3%. The rates of follow-up were 52.7% at 10 years, 38.3% at 15 years, and 10.3% at 20 years. Recurrence was confirmed in 850 patients in total (16.2%) and in 50 patients beyond 5 years. The adequate follow-up endpoints according to stage (with < 1% recurrence risk) were 2 years for stage IA, 4 years for IB, 6 years for IIA, 9 years for IIB, 7 years for IIIA, and 8 years for IV (curative). For stage IIIB and IIIC, the recurrence risk remained. CONCLUSIONS: The adequate surveillance duration of resected gastric cancer might be different in each stage. Although the follow-up duration for stage I disease could be reduced to less than 5 years, advanced gastric cancer such as stage III or IV disease has risk of recurrence beyond 5 years and therefore additional follow-up is required. These results could help decide the strategy for surveillance.

Impact of Primary Tumor Resection on Mortality in Patients with Stage IV Colorectal Cancer with Unresectable Metastases: A Multicenter Retrospective Cohort Study.

BACKGROUND: Primary tumor resection (PTR) before commencing systemic chemotherapy in patients with stage IV colorectal cancer and unresectable metastases (mCRC) remains controversial. This study aimed to assess whether PTR before systemic chemotherapy is associated with mortality in mCRC patients, after adjusting for confounding factors, such as the severity of the primary tumor and metastatic lesions. METHODS: We analyzed hospital-based cancer registries from nine designated cancer hospitals in Fukushima Prefecture, Japan. Patients were divided into two groups (PTR and non-PTR), based on whether PTR was performed as initial therapy for mCRC or not. The primary outcome was all-cause mortality. Kaplan-Meier survival analysis was performed, and survival estimates were compared using the log-rank test. Adjusted hazard ratios were calculated using Cox regression to adjust for confounding factors. All tests were two-sided; P-values < 0.05 were considered statistically significant. RESULTS: Between 2008 and 2015, 616 mCRC patients were included (PTR: 414 [67.2%]; non-PTR: 202 [32.8%]). The median follow-up time was 18.0 (interquartile range [IQR]: 8.4-29.7) months, and 492 patients (79.9%) died during the study period. Median overall survival in the PTR and non-PTR groups was 23.9 (IQR: 12.2-39.9) and 12.3 (IQR: 6.2-23.8) months, respectively (P < 0.001, log-rank test). PTR was significantly associated with improved overall survival (adjusted hazard ratio: 0.51; 95% confidence interval: 0.42-0.64, P < 0.001). CONCLUSIONS: PTR before systemic chemotherapy in patients with mCRC was associated with improved survival.

Nutritional intervention after an early assessment by a flexible endoscopic evaluation of swallowing is associated with a shorter hospital stay for patients with acute cerebral infarction: A retrospective study.

BACKGROUND AND OBJECTIVES: It is important to evaluate the swallowing function of patients with acute cerebral infarction. The effects of nutritional intervention after an early assessment by a flexible endoscopic evaluation of swallowing (FEES) were evaluated. METHODS AND STUDY DESIGN: This retrospective study included 274 patients who were hospitalized for acute cerebral infarction and underwent a FEES between 2016 and 2018. The effects of early nutritional intervention after an assessment by a FEES within 48 h from admission were evaluated. The patients were divided into a shorter hospital stay group (<30 days) and a longer group (≥30 days). A multivariate analysis was performed to identify the predictive factors for a shorter hospital stay. RESULTS: The overall patient characteristics were as follows: 166 men; median age, 81 years old; and median body mass index (BMI), 21.1 kg/m2. No significant differences in the age, sex, or BMI were found between the shorter and longer hospital stay groups. A FEES within 48 h of admission (odds ratio [OR], 2.040; 95% confidence interval [CI], 1.120-3.700; p=0.019), FILS level ≥6 at admission (OR, 2.300; 95% CI, 1.190-4.440; p=0.013), and an administered energy dose of ≥18.5 kcal/kg on hospital day 3 (OR, 2.360; 95% CI, 1.180-4.690; p=0.015) were independently associated with a hospital stay <30 days. CONCLUSIONS: Patients with acute cerebral infarction are more likely to have a shorter hospital stay (<30 days) if they undergo a FEES early after admission and receive optimal nutritional intervention.

Prediction of oral intake recovery for inpatients with aspiration pneumonia by videoendoscopic evaluation using the Hyodo-Komagane score in Japan.

OBJECTIVE: To verify the validity of the prediction of oral intake recovery for inpatients with aspiration pneumonia using the Hyodo-Komagane score. BACKGROUND: Patients admitted for treatment of aspiration pneumonia sometimes have difficulty in resuming oral intake due to decreased swallowing function. Predicting whether the swallowing function will recover enough to achieve oral ingestion at discharge is an important factor in developing a treatment strategy. No studies have investigated the prediction of oral intake recovery using videoendoscopic examination. METHODS: Subjects were 65 patients who were admitted to an acute care hospital for the treatment of aspiration pneumonia. The patients were divided into two groups, the oral feeding group and the tube feeding group, according to their oral intake status at discharge or transfer. Logistic regression analysis was performed using the condition that tube feeding was not required as an objective variable and the items with significant differences between the two groups as explanatory variables. Additionally, the receiver operating characteristic curve was used to identify patients who could take food orally at discharge. RESULTS: The odds ratios for the Hyodo-Komagane score and the pharyngeal clearance score were 1.485 and 3.379, respectively. When the cut-off values of the Hyodo-Komagane score and the pharyngeal clearance score were 6 and 1, the sensitivity was 0.88 and 0.91, and the specificity was 0.64 and 0.70, respectively. CONCLUSION: The Hyodo-Komagane score and especially the pharyngeal clearance score are useful indices to predict oral intake recovery for inpatients with aspiration pneumonia.

Effects of 12-month exercise intervention on physical and cognitive functions of nursing home residents requiring long-term care: a non-randomised pilot study.

AIMS: We performed a 12-month exercise intervention for 'nursing home for the elderly' residents requiring long-term care. We evaluated changes in their muscular strength, muscle mass, and cognitive function. METHODS: Thirty-seven nursing home residents (Mini-Mental State Examination (MMSE): 14.7 ± 7.0, Barthel Index: 44.2 ± 18.9) were enrolled. We divided the participants into the exercise intervention group (n = 19) and non-intervention group (n = 18) ensuring no significant difference in the participants' characteristics at baseline. For the exercise intervention group, exercise was performed for about 40 min twice a week for 12 months. Skeletal Mass Index and grip force were determined to evaluate muscle mass and muscle strength, respectively. MMSE, Trail Making Test (TMT) part A, and Geriatric Depression Scale 15 (GDS15) were used for cognitive function evaluation, with their changes investigated. RESULTS: After 12 months, the MMSE scores were significantly improved in the exercise intervention group compared with the non-intervention group (change from baseline to 12 months: Non-intervention: -1.0 ± 2.8, Intervention: 1.2 ± 3.0; P = 0.04). Moreover, the grip force of the dominant arm was significantly improved in the exercise intervention group compared with the non-intervention group (change from baseline to 12 months: Non-intervention: -1.3 ± 2.8 kg, Intervention: 1.4 ± 4.6 kg; P = 0.007). The prevalence of sarcopenia was significantly increased after 12 months compared with baseline in the non-intervention group (Non-intervention: 61.1% → 75.0%, Intervention: 77.8% → 71.4%; P < 0.02). There were no significant changes in GDS15, Barthel Index and TMT after 12 months in intervention and non-intervention groups. CONCLUSION: Exercise intervention may be effectively used for improving the physical and cognitive functions of nursing home residents requiring long-term care.

Comparative efficacy and acceptability of 21 antidepressant drugs for the acute treatment of adults with major depressive disorder: a systematic review and network meta-analysis.

BACKGROUND: Major depressive disorder is one of the most common, burdensome, and costly psychiatric disorders worldwide in adults. Pharmacological and non-pharmacological treatments are available; however, because of inadequate resources, antidepressants are used more frequently than psychological interventions. Prescription of these agents should be informed by the best available evidence. Therefore, we aimed to update and expand our previous work to compare and rank antidepressants for the acute treatment of adults with unipolar major depressive disorder. METHODS: We did a systematic review and network meta-analysis. We searched Cochrane Central Register of Controlled Trials, CINAHL, Embase, LILACS database, MEDLINE, MEDLINE In-Process, PsycINFO, the websites of regulatory agencies, and international registers for published and unpublished, double-blind, randomised controlled trials from their inception to Jan 8, 2016. We included placebo-controlled and head-to-head trials of 21 antidepressants used for the acute treatment of adults (≥18 years old and of both sexes) with major depressive disorder diagnosed according to standard operationalised criteria. We excluded quasi-randomised trials and trials that were incomplete or included 20% or more of participants with bipolar disorder, psychotic depression, or treatment-resistant depression; or patients with a serious concomitant medical illness. We extracted data following a predefined hierarchy. In network meta-analysis, we used group-level data. We assessed the studies' risk of bias in accordance to the Cochrane Handbook for Systematic Reviews of Interventions, and certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation framework. Primary outcomes were efficacy (response rate) and acceptability (treatment discontinuations due to any cause). We estimated summary odds ratios (ORs) using pairwise and network meta-analysis with random effects. This study is registered with PROSPERO, number CRD42012002291. FINDINGS: We identified 28 552 citations and of these included 522 trials comprising 116 477 participants. In terms of efficacy, all antidepressants were more effective than placebo, with ORs ranging between 2·13 (95% credible interval [CrI] 1·89-2·41) for amitriptyline and 1·37 (1·16-1·63) for reboxetine. For acceptability, only agomelatine (OR 0·84, 95% CrI 0·72-0·97) and fluoxetine (0·88, 0·80-0·96) were associated with fewer dropouts than placebo, whereas clomipramine was worse than placebo (1·30, 1·01-1·68). When all trials were considered, differences in ORs between antidepressants ranged from 1·15 to 1·55 for efficacy and from 0·64 to 0·83 for acceptability, with wide CrIs on most of the comparative analyses. In head-to-head studies, agomelatine, amitriptyline, escitalopram, mirtazapine, paroxetine, venlafaxine, and vortioxetine were more effective than other antidepressants (range of ORs 1·19-1·96), whereas fluoxetine, fluvoxamine, reboxetine, and trazodone were the least efficacious drugs (0·51-0·84). For acceptability, agomelatine, citalopram, escitalopram, fluoxetine, sertraline, and vortioxetine were more tolerable than other antidepressants (range of ORs 0·43-0·77), whereas amitriptyline, clomipramine, duloxetine, fluvoxamine, reboxetine, trazodone, and venlafaxine had the highest dropout rates (1·30-2·32). 46 (9%) of 522 trials were rated as high risk of bias, 380 (73%) trials as moderate, and 96 (18%) as low; and the certainty of evidence was moderate to very low. INTERPRETATION: All antidepressants were more efficacious than placebo in adults with major depressive disorder. Smaller differences between active drugs were found when placebo-controlled trials were included in the analysis, whereas there was more variability in efficacy and acceptability in head-to-head trials. These results should serve evidence-based practice and inform patients, physicians, guideline developers, and policy makers on the relative merits of the different antidepressants.
