Impact of a Mindfulness Mobile Application on Weight Loss and Eating Behavior in People with Metabolic Syndrome: a Pilot Randomized Controlled Trial.

BACKGROUND: Weight-loss approaches involving mindfulness have been reported to reduce overeating behavior. We conducted a preliminary evaluation of the feasibility and effectiveness of a mindfulness mobile application (MMA) combined with a comprehensive lifestyle intervention (CLI) focused on weight loss and eating behaviors for people with metabolic syndrome based on post-intervention follow-up data. METHOD: Participants were randomly assigned (1:1) to a CLI group or a CLI + MMA group. Participants received weekly CLI for 13 weeks, followed by telephone counseling for 13 weeks. The CLI + MMA group also had access to the MMA. Feasibility was assessed by the number of people who refused to participate, rate of adherence to the MMA, follow-up rate, and participant satisfaction. The preliminary endpoint was weight change (at 26 weeks). Participants completed the Dutch Eating Behavior Questionnaire (DEBQ). A mixed linear model was used for efficacy analysis. RESULTS: Eight of the 40 participants declined to participate. The MMA was used 4.4 ± 1.7 days per week, but the rate of adherence declined over time. The follow-up rate was 100%, and there was no difference in participant satisfaction between the groups. There was no significant group-by-time interaction for weight loss (p = 0.924), but there was a significant interaction for the DEBQ restrained eating score (p = 0.033). CONCLUSIONS: This study found that CLI plus MMA was highly feasible and moderately acceptable. There were no significant differences in weight loss between the groups, but the CLI + MMA group showed an increase in restrained eating. Further large-scale studies are needed.

A case of Erdheim-Chester disease with the BRAF V600E mutation diagnosed via endoscopic sinus surgery.

Erdheim-Chester disease is characterized by the infiltration of foamy histiocytes in tissues. Lesional tissue biopsy is recommended to confirm diagnosis and establish the BRAF mutational status. A 52-year-old man presented to our hospital with hydronephrosis. Computed tomography showed enhancement of soft shadows around the left renal pelvis transition area and the aorta. He was treated with prednisolone 0.2 mg/kg for 1 year; however, no improvement was observed. 18Fluorodeoxyglucose-positron emission tomography/computed tomography revealed increased fluorodeoxyglucose uptake in various body parts, including the maxillary sinuses, indicative of Erdheim-Chester disease. He refused further examination, and the maxillary sinus lesions were treated with antibiotics and intranasal steroids, but no improvement was observed. Two years later, he underwent biopsy with endoscopic sinus surgery of the maxillary sinus, which showed the highest increase in fluorodeoxyglucose uptake on repeat 18fluorodeoxyglucose-positron emission tomography/computed tomography. Endoscopic findings showed only nonspecific inflammatory findings, but pathological findings revealed the proliferation of cells with abundant foamy cytoplasms. Sufficient tumor volume was available to perform PCR for BRAF V600E mutation analysis, which was positive and resulted in a diagnosis of Erdheim-Chester disease with the BRAF V600E mutation. This is the first case of a patient with Erdheim-Chester disease with the BRAF V600E mutation identified in a sinus lesion. Endoscopic sinus surgery biopsy of the paranasal sinuses was considered to contribute to the histological and genetic diagnosis of Erdheim-Chester disease, particularly following the notable increase in fluorodeoxyglucose uptake.

＜Editors' Choice＞ Myelodysplastic syndrome with trisomy 8 presenting periodic fever and multiple MEFV gene variants outside exon 10: a case report.

Myelodysplastic syndrome is associated with the development of autoinflammatory conditions, such as recurrent fever, polymyalgia, arthralgia, and erythema. Trisomy 8 is a common chromosomal abnormality in patients with myelodysplastic syndrome. Myelodysplastic syndrome with trisomy 8 involves autoinflammatory conditions, especially Behçet's disease-like symptoms with intestinal mucosal damage. MEFV variants, particularly those in exon 10, are pathogenic in familial Mediterranean fever, the most common autoinflammatory disease, presenting typical symptoms such as periodic fever and pleuritis/pericarditis/peritonitis. MEFV variants outside exon 10 are common in Japanese patients with familial Mediterranean fever and are associated with atypical symptoms, including myalgia and erythema. MEFV variants in myelodysplastic syndrome with trisomy 8 have rarely been investigated, although myelodysplastic syndrome with trisomy 8 might develop autoinflammatory conditions similar to those in familial Mediterranean fever. We encountered a 67-year-old man who had myelodysplastic syndrome with trisomy 8 and multiple MEFV variants outside exon 10. He presented with periodic fever, as well as chest/abdominal pain, myalgia, and erythema, although the symptoms did not fulfill the diagnostic criteria of familial Mediterranean fever. We discussed the possibility that these symptoms are modified by MEFV variants outside exon 10 in myelodysplastic syndrome with trisomy 8.

Strongyloidiasis presenting during treatment of low-dose glucocorticoid plus rituximab for anti-signal recognition particle antibody-positive polymyositis: A case report.

Strongyloidiasis, an intestinal parasitic infection caused by Strongyloides stercoralis, rarely occurs in Japan. When treated with immunosuppressive drugs, two potentially lethal conditions, hyperinfection and dissemination, may develop in asymptomatic carriers of this parasite. We report the development of strongyloidiasis during treatment of polymyositis with glucocorticoids plus rituximab (RTX). A 44-year-old woman had been diagnosed with anti-signal recognition particle antibody-positive polymyositis with interstitial pneumonia 6 years previously, for which she had recently been receiving prednisolone at 5 mg/day and RTX at 375 mg/m2 twice every 3 months. Her condition appeared to be well controlled. She was admitted to our hospital with a 1-month history of chronic diarrhoea and epigastric pain. Standard microscopic examination of a sample of faeces revealed the presence of S. stercoralis; however, serologic testing for parasites was negative. Treatment with ivermectin alleviated her inflammatory diarrhoea and eradicated the faecal parasites. We believe that our patient had an exacerbation of S. stercoralis infection (hyperinfection syndrome) that was exacerbated by low-dose glucocorticoids plus RTX. Strongyloidiasis should be considered in immunocompromised individuals with unexplained diarrhoea, even in non-endemic areas.

Family Issues in Japanese Clinics: Concordance between Patients' and Physicians' Views.

INTRODUCTION: The objectives of the present study were to clarify the frequency and content of family issues for patients in Japanese clinics, and the concordance between physicians' and patients' views of family issues. METHODS: In this study, we used a cross-sectional design with a questionnaire survey. Participants were outpatients and their physicians in charge (four family physicians) at four Japanese clinics. The main body of research was conducted between April 5 and May 15, 2004. After obtaining oral informed consent, the physician in charge distributed questionnaires to participating patients to complete at home. The questionnaire comprised three items: 1) Do you have any worries about your family? 2) Are you comfortable consulting a physician regarding your family issue?, and 3) If possible, could you tell us why you feel like that?Participants provided written informed consent and answered the questionnaire before sealing it in an envelope and posting it back to the research center. Physicians in charge completed their version of the questionnaire and independently sent the data to the center. RESULTS: Of the 272 participating patients, 118 (45.6%) had family issues. "Health problems with family members" (28%) and "family life cycle issues" (19.5%) were the main content of these issues. Physicians indicated that 45.7% of patients had family issues. The rate of concordance between physicians' and patients' perspectives regarding family issues was 46.6%. CONCLUSIONS: Family issues can therefore be regarded as a common health problem due to the frequency. There was some inconsistency between physicians' and patients' views, but much of this discrepancy may be resolved by developing the specialty of family practice.

Clinical characteristics of Corynebacterium simulans.

Corynebacterium simulans was first reported in 2000. Its characteristics such as isolation frequency, specimen types, and antimicrobial susceptibilities are poorly understood, because identification is difficult using conventional methods. We performed a retrospective observational study of 13 and 317 strains of C. simulans and C. striatum, respectively, isolated from consecutive patients at Nagoya University Hospital from January 2017 to December 2018. We analyzed patients' backgrounds, types of specimens, and antimicrobial susceptibilities. Antimicrobial susceptibilities were compared with those of C. striatum. The frequencies of isolation of C. simulans and C. striatum were 3.9% and 96%, respectively. C. simulans was not detected in specimens associated with mucous membranes, such as sputum and secretions from the craniocervical region, which were frequent for C. striatum. C. simulans was mainly detected in the skin (61.5%). All C. simulans isolates were susceptible to anti-MRSA drugs, as well as to numerous other antibiotics, including those that are orally administered. For example, C. simulans was significantly more susceptible to penicillin G, ceftriaxone, and ciprofloxacin than C. striatum (respective susceptibilities: 66.7% vs 5.4%, 50.0% vs 4.0%, 66.7% vs 5.9%). There was no significant difference between meropenem and erythromycin, although susceptibility to each was relatively high (100.0% vs 31.7%, 50.0% vs 11.9%). C. simulans was susceptible to numerous orally administered antibiotics and more susceptible to antimicrobial drugs than C. striatum. C. simulans was detected less frequently than C. striatum and was infrequently detected in specimens associated with mucous membranes. These characteristics will aid the selection of optimal antimicrobial therapies.

Impact of telephone support programme using telemonitoring on stage of change towards healthy eating and active exercise in people with prediabetes.

INTRODUCTION: This study evaluated the impact of a telephone support programme with telemonitoring on changes in healthy eating and active exercise in adults with prediabetes using the stage of change framework. METHODS: We performed a post hoc analysis using data from the Japan Diabetes Outcome Trial-1. A total of 2607 participants aged 20-65 years with impaired fasting glucose were recruited from the workplace/community in Japan and randomized to a one year telephone support programme intervention arm (n = 1240) or self-directed control arm (n = 1367). Participants in both arms received monthly data feedback from a weight scale and pedometer. The main outcome measure was the stages of change toward healthy eating and active exercise. The secondary outcome was fasting plasma glucose (FPG). RESULTS: After the one year intervention, the adjusted odds ratio of progressing to the action/maintenance stage in the intervention vs. control arm for healthy eating was 1.31 (95% confidence interval (CI) 1.21-1.43; p < 0.001), but that for active exercise was 1.07 (95% CI 0.99-1.15; p = 0.062). The intervention decreased FPG levels in participants in the contemplation stage, but not in the precontemplation, preparation and action/maintenance stages. DISCUSSION: These findings suggest that the telephone support programme by healthcare providers advanced the stage of changes toward healthy eating in people with prediabetes. In particular, it decreased FPG levels in the contemplation stage.

A combination of herbal formulas, acupuncture, and novel pine-needle stimulation for recurrent alopecia areata: A case report.

INTRODUCTION: Head hair is a symbol of vitality, and hair loss by alopecia areata (AA) presents a burden on patients. Although traditional Japanese Kampo medicine (JKM) formulas, acupuncture, and moxibustion have historically been used for treating AA, no studies have utilized a combination of these modalities. PATIENT CONCERNS: A 34-year-old male with a history of childhood asthma presented with a sudden hair loss at the top of his head without any preceding symptoms. Except for a hairless patch of 5 cm × 6 cm, his general appearance was otherwise good. The patient underwent topical immunotherapy on visiting a dermatologist. However, the patient noticed an exacerbation of his hairless lesion. DIAGNOSIS: The AA diagnosis was established based on clinical appearance and dermatological findings. The Severity of Alopecia Tool (SALT) score for alopecia was 19% at diagnosis. INTERVENTIONS: The patient received 2 JKM formulas (saikokaryukotsuboreito and shichimotsukokato) in combination with acupuncture. When relapse occurred, a novel self-administration of pine-needle acupuncture was initiated in combination with the JKM formulas. OUTCOMES: A 50% recovery from the baseline SALT score was achieved using JKM formulas in combination with acupuncture for 4 months. The patient achieved complete remission for 5 months. However, another stressful event induced an AA relapse with multiple lesions harboring a SALT score of 13%. Pine-needle acupuncture was initiated, resulting in faster resolution than the first treatment. Recoveries of 50% and 75% were achieved 3 and 4 months after relapse, respectively, and a long-lasting response without relapse was obtained for at least 3 years. CONCLUSION: A combination of multimodal traditional therapies, including JKM formulas, acupuncture, and self-administered pine-needle stimulation, represents an effective integrative treatment for patients with AA.

Effect of physician attire on patient perceptions of empathy in Japan: a quasi-randomized controlled trial in primary care.

BACKGROUND: There is limited quantitative research on the effect of physician attire on patient-physician relationships. This study aimed to measure the influence of Japanese family physicians' attire on the "human" aspects of medical care in terms of patient-perceived relational empathy. METHODS: This was a multicenter, prospective, controlled trial conducted in primary clinics in Japan. We explored the effects of family physician attire (white coat vs. casual attire) on patient-perceived empathy. Family physicians were allocated to alternate weeks of wearing a white coat or casual attire during consultations. Patients' perceptions of physician empathy were evaluated using the self-rated Japanese Consultation and Relational Empathy (CARE) Measure. We used a linear mixed model to analyze the CARE Measure scores, adjusting for cluster effects of patients nested within doctor, age, and sex of patients, and doctors' sex and years of clinical experience. We used the same method with Bonferroni adjustment to analyze patient sex differences in perceived empathy. RESULTS: A total of 632 patients of seven family physicians were allocated to white coat-wearing consultations (n = 328), and casual attire-wearing consultations (n = 304). There was no difference in CARE Measure scores between white coat and casual primary care consultations overall (p = 0.162). Subgroup analysis of patient sex showed that CARE Measure scores of male patients were significantly higher in the Casual group than in the White coat group (adjusted p-value = 0.044). There was no difference in female patient scores between White coat and Casual groups (adjusted p-value = 1.000). CONCLUSIONS: This study demonstrated that physician attire (white coat or casual attire) in a primary care setting did not affect patient-perceived relational empathy overall. However, male patients of physicians wearing casual attire reported higher physician empathy. Although empathy cannot be reduced to simple variables such as attire, white coats may have a negative effect on patients, depending on the context. Family physicians should choose their attire carefully. TRIAL REGISTRATION: Japanese University Hospital Medical Information Network (UMIN-ICDR).

A structured summary of a study protocol for a multi-center, randomized controlled trial (RCT) of COVID-19 prevention with Kampo medicines (Integrative Management in Japan for Epidemic Disease by prophylactic study: IMJEDI P1 study).

OBJECTIVE: We aimed to test our hypothesis that traditional Japanese (Kampo) medicine, hochuekkito (Hochu-ekki-to: HET) has a preventive effect for the symptoms on COVID-19. TRIAL DESIGN: The study is designed as a multi-center, interventional, parallel-group, randomized (1:1 ratio), investigator sponsored, two-arm study. PARTICIPANTS: Six thousand participants will be recruited from healthy hospital workers in 7 Japanese University Hospitals. INCLUSION CRITERIA: 1. Age from 20 to 75 years old at the time of registration 2. Asymptomatic and body temperature below 37°C at the time of registration 3. Capable of eating orally Exclusion criteria: 1. Previous upper respiratory inflammation due to viral infection (including suspected COVID-19) 2. Taking immunosuppressants 3. Allergic to the Kampo medicines used in this study 4. History of hypokalaemia, severe hypertension, severe liver dysfunction, and interstitial pneumonia 5. Regularly taking other Kampo medicines 6. Pregnant or possibly pregnant 7. Participating in other research 8. Judged to be unsuitable for this study by the doctor in charge INTERVENTION AND COMPARATOR: Kampo group: participants receive HET in 9 tablets 2 times per day for 8 weeks. CONTROL GROUP: participants receive placebo in the same dosage as the Intervention group - 9 tablets 2 times per day for 8 weeks. Placebo tablets are identical in appearance and package to HET. Taste of placebo is different from that of HET. The Ohsugi Pharmaceutical Co. Ltd, Osaka, Japan manufactured the placebo and HET. MAIN OUTCOMES: Primary outcome: Number of patients with a SARS-CoV-2 RNA by ploymerase chain reaction (PCR) positive result with at least one symptom (fever, cough, sputum, malaise, shortness of breath) during the 12-week study period (including the 4-week observation period after oral administration). SECONDARY OUTCOMES: 1. Period from infection to onset 2. Period from the appearance of symptoms to the disappearance of PCR positive 3. Number of days until the appearance or improvement of symptoms 4. Severe stage: presence of hospitalization 5. Shock stage: ICU management required for mechanical ventilation, shock vitals or failure of organ(s) other than lungs Safety endpoints include numbness in the hands and/or feet, edema, skin rash or other allergic symptoms, and gastric discomfort. RANDOMISATION: Patients are randomized (1:1 ratio) to each group using minimization implemented with the Electric data capture system (DATATRAK Enterprise Cloud), with balancing of the arms with age range (under 50 years of age or not) and having a history of risk factors for COVID-19 (cardiovascular disease, hypertension, diabetes, respiratory diseases). BLINDING (MASKING): Only participants will be randomized. NUMBERS TO BE RANDOMISED (SAMPLE SIZE): The main research hypothesis of this study is that Kampo medicines significantly prevent the onset of COVID-19. It is assumed that the infection rate before the administration of the drug under consideration will be 0% and that the incidence of COVID-19 thereafter will be 2- 3%, of which 70%-80% will show symptoms of COVID-19. Assuming that the pharmaceutical effect of the drug will be effective in 50% of patients and that the incidence rates in the placebo and drug groups will be 1.4%-2.4% and 0.7%-1.2%, respectively, the placebo is calculated at 2%, and the study drug at 1%. Since the frequency of verification is low and the number of cases will be large, we set a total of 10 analyses (9 interim analyses and a final analysis). Since the number of cases at the time of the final analysis will be 4,986 under the conditions of α = 0.05 and a power of 80% by the Peto method. We set at 600 cases in each interim analysis with an estimated dropout rate of 16.9%. Finally, the total number of cases is set to 6,000 with 3,000 in the placebo group and 3,000 in the HET group. TRIAL STATUS: Protocol version 1.3 of October 23rd , 2020. Recruitment start (expected): December 1st, 2020. Recruitment finish (expected): December 31st, 2022. TRIAL REGISTRATION: This trial is registered in the Japan Registry of Clinical Trials (jRCT) ( jRCTs031200150 ) on 14 October 2020. FULL PROTOCOL: The full protocol is attached as an additional file, accessible from the Trials website (Additional file 1).

A survey of Japanese physician preference for attire: what to wear and why.

Many studies have examined the impression made on patients by physicians' attire. Regardless of practice location, many patients express most confidence in physicians who wear white coats. The number of physicians in Japan who choose not to wear white coats in practice has been increasing, particularly in primary care settings. However, very few studies have examined physician preference for attire. To clarify Japanese general practitioners' preference for attire by practice setting, we conducted a survey of physician preferences and reasons for attire selection. Subjects were 794 general practitioners certified by the Japan Primary Care Association and recruited from a mailing list. We conducted a web-based questionnaire survey. Physicians were asked to choose one of four different dress styles (semi-formal, white coat, scrubs, and casual) for different practice settings and state the reasons for selection. The response rate was 19.3% (n = 153; men 112). Most subjects chose white coats as usual attire for hospital practice (52%), mainly because of custom and professionalism. In contrast, most subjects chose non-white coats for clinics (59%) and home care (hospital-provided, 58%; clinic-provided, 71%). More subjects chose casual dress for clinic and home care practice, mainly to appear empathic. Most subjects chose white coats as the most appropriate hospital attire (54%), mainly because of patient perceptions of this attire being professional. Most subjects considered non-white coat attire more appropriate for clinic and home care practice. The findings indicate that general practitioners choose their clothes depending on practice location.

Self-weighing frequency and the incidence of type 2 diabetes: post hoc analysis of a cluster-randomized controlled trial.

OBJECTIVES: Frequent self-weighing is associated with weight loss and maintenance, but the relationship between frequent self-weighing and the incidence of type 2 diabetes (T2D) remains unclear. The study aim was to examine the association between self-weighing frequency and the incidence of T2D in people with impaired fasting glucose (IFG). RESULTS: We tested the hypothesis that self-weighing frequency and the incidence of T2D are associated in 2607 people with IFG (1240 in the intervention arm; 1367 in the self-directed control arm). Both arms received a weighing scale with storage function. Healthcare providers offered a one-year goal-focused lifestyle intervention via phone. Participants were divided into 4 categories based on self-weighing frequency (No data sent [reference group], low: < 2 times/week, middle: 3-4 times/week, and high: 5-7 times/week). The adjusted hazard ratio (AHR) and 95% confidence interval (CI) were calculated. In the intervention arm, middle- and high-frequency self-weighing were associated with a decreased incidence of T2D relative to the reference group (AHR = 0.56, 95% CI [0.32, 0.98] and AHR = 0.43, 95% CI [0.25, 0.74], respectively). In the control arm, high-frequency self-weighing was also associated with a decreased incidence of T2D relative to the reference group (AHR = 0.54, 95% CI [0.35, 0.83]). Trial registration This trial has been registered with the University Hospital Medical Information Network (UMIN000000662).

Effects of obesity, metabolic syndrome, and non-alcoholic or alcoholic elevated liver enzymes on incidence of diabetes following lifestyle intervention: A subanalysis of the J-DOIT1.

OBJECTIVES: Using annual health check-up data, the aim of this study was to identify target populations for lifestyle interventions to effectively prevent diabetes in a real-world setting. METHODS: The Japan Diabetes Outcome Intervention Trial-1, a prospective, cluster-randomized controlled trial, was launched to test if year-long telephone-delivered lifestyle support by health professionals can prevent the development of type 2 diabetes (T2D) in people with impaired fasting glucose (IFG) identified at health check-ups. A total of 2607 participants aged 20-65 years with IFG were randomized to an intervention arm (n = 1240) or a control arm (n = 1367). We performed subgroup analysis to examine the effects of the intervention on the incidence of T2D in participants with body mass index (BMI) ≥25, metabolic syndrome (MetS), and non-alcoholic or alcoholic elevated liver enzymes at the baseline. Cox regression analysis adjusted for sex was used to calculate the hazard ratios (HRs). RESULTS: In addition to IFG, the presence of BMI ≥25, MetS, and elevated liver enzymes increased the incidence of diabetes by two- or three-fold. During a median follow-up period of 4.9 years, only the non-alcoholic elevated liver enzyme group showed a low incidence rate owing to lifestyle interventions (adjusted HR: 0.42, 95% confidence interval: 0.18-0.98). CONCLUSION: The results suggest that people who have IFG and non-alcoholic elevated liver enzymes are a good target population for lifestyle interventions to effectively reduce the incidence of diabetes in a real-world setting.

Establishment of the experimental procedure for prediction of conjugation capacity in mutant UGT1A1.

UDP-glucuronosyltransferase 1A1 (UGT1A1) is an enzyme that is found in the endoplasmic reticulum membrane and can reportedly have a large number of amino acid substitutions that result in the reduction of glucuronidation capacity. For example, adverse drug reactions when patients receive CPT-11 (irinotecan) such as in cancer chemotherapy are caused by amino acid substitutions in UGT1A1. We previously found that the extent of the docking when the hydroxyl residue of bilirubin was oriented toward UDP-glucuronic acid correlated with in vitro conjugation capacity. In this study, we analyzed the conformation of mutant UGT1A1s by means of structural optimization with water and lipid bilayers instead of the optimization in vacuo that we used in our previous study. We then derived a mathematical model that can predict the conjugation capacities of mutant UGT1A1s by using results of substrate docking in silico and results of in vitro analysis of glucuronidation of acetaminophen and 17ß-estradiol by UGT1A1s. This experimental procedure showed that the in silico conjugation capacities of other mutant UGT1A1s with bilirubin or SN-38 were similar to reported in vitro conjugation capacities. Our results suggest that this experimental procedure described herein can correctly predict the conjugation capacities of mutant UGT1A1s and any substrate.

Fatal case of TAFRO syndrome associated with over-immunosuppression: a case report and review of the literature.

TAFRO syndrome is a novel disease concept characterized by Thrombocytopenia, Anasarca, myeloFibrosis, Renal dysfunction, Organomegaly, multiple lymphadenopathy and a histopathological pattern of atypical Castleman's disease. A 58-year-old man was diagnosed as TAFRO syndrome by clinical and histopathological findings. After receiving intensive immunosuppressive therapy, his thrombocytopenia and anasarca had not improved. He developed complications such as methicillin-resistant Staphylococcus aureus sepsis, gastrointestinal bleeding, peritonitis caused by Stenotrophomonas maltophilia, gastrointestinal perforation, and disseminated candidiasis resulting in death. Autopsy revealed disseminated candidiasis and hemophagocytic lymphohistiocytosis, with no evidence of TAFRO syndrome. During treatment, we regarded his lasting thrombocytopenia and anasarca as insufficient control of TAFRO syndrome. However, the autopsy revealed that thrombocytopenia was caused by secondary hemophagocytic lymphohistiocytosis caused by over-immunosuppression. We reviewed the published literature to identify indicators of adequate treatment, which suggested improvement of platelet count and anasarca several weeks after initial therapy. This indicated that we could not depend on the platelet count and anasarca in acute medical care after initial treatment. We should treat TAFRO syndrome based on patients' clinical status and obviate the risk of treatment-related complications caused by over-immunosuppression.

Prevention of Metabolic Syndrome by Telephone-Delivered Lifestyle Intervention in a Real-World Setting: Sub-Analysis of a Cluster-Randomized Trial.

Background: Evidence of the long-term benefits of telephone-delivered lifestyle interventions is limited. This study investigated the ability of telephone-delivered lifestyle intervention to reduce the incidence of metabolic syndrome (MetS) in subjects diagnosed with impaired fasting glucose (IFG) during health checkups. Methods: Our subjects were participants in the Japan Diabetes Outcome Intervention Trial-1 (J-DOIT1), a prospective, cluster-randomized controlled trial designed to investigate whether goal-focused lifestyle coaching over the telephone can effectively reduce the incidence of type 2 diabetes development in high-risk individuals in a primary health care setting. We extracted 753 and 844 J-DOIT1 participants from the intervention and controls arms, respectively, who had IFG but did not meet the MetS criteria at baseline. The intervention arm received goal-focused lifestyle support delivered by health care providers via telephone over a 1-year period. The endpoint was the development of incident MetS, defined based on the Adult Treatment Panel III criteria modified for Japan. Results: During the median follow-up period of 4.9 years, 8.0% of the intervention arm and 12.0% of the control arm developed MetS. Overall, the hazard ratio (HR) for the development of MetS was 0.75 [95% confidence interval (CI), 0.52-1.09; P = 0.14] in the intervention arm. However, the HR in overweight or obese [body mass index (BMI) ≥23 kg/m2] individuals was significantly reduced to 0.63 (95% CI, 0.41-0.95; P = 0.029), but not in lean (BMI <23 kg/m2) individuals. Conclusion: Telephone-delivered lifestyle intervention effectively reduced the incidence of MetS in overweight and obese subjects in a real-world setting.

Nasogastric Tubes Can Cause Intramural Hematoma of the Esophagus.

BACKGROUND Intramural hematoma of the esophagus (IHE), a rare manifestation of acute mucosal injuries of the esophagus, can be caused by trauma such as endoscopic surgeries. Coagulation disorders increase the risk of IHE. The most common location of IHE is in the distal esophagus. The characteristic clinical triad of manifestations comprises acute retrosternal pain, odynophagia or dysphagia, and hematemesis. It is important to distinguish IHE from other acute conditions such as acute coronary syndrome, aortic dissection, and pulmonary embolism. CASE REPORT An 84-year-old male was scheduled for coil embolization for an endoleak after endovascular aneurysm repair. For this reason, he was taking aspirin and warfarin. A nasogastric tube had been inserted during surgery and subsequently removed without any problems reported. Postoperatively, he experienced chest pain and hematemesis of sudden onset. Urgent esophagogastroduodenoscopy demonstrated a large, dark red, non-pulsatile, submucosal, esophageal mass in the area of the mid-esophagus with a little oozing. He was diagnosed as having an IHE; other possible diagnoses were excluded by contrast-enhanced computed tomography and aortography. He was treated with fasting, a proton pump inhibitor, and cessation of anti-thrombotic drugs; he recovered completely. The bleeding spot in the esophagus was in the area of the mid-esophagus, which was around the second natural constriction site. It was possible that the nasogastric tube had contact with the esophageal wall at this second natural constriction, and caused intramural esophageal bleeding. CONCLUSIONS Nasogastric tubes are not generally recognized as a cause of IHE. However, they can cause them, especially when a patient is taking anti-thrombotic drugs.

Skills acquisition for novice learners after a point-of-care ultrasound course: does clinical rank matter?

BACKGROUND: Few studies have compared the effectiveness of brief training courses on point-of-care ultrasound (POCUS) skill acquisition of novice attending physicians vs. trainees. The purpose of this study was to evaluate the change in POCUS image interpretation skills and confidence of novice attending physicians vs. trainees after a 1-day POCUS training course. METHODS: A 1-day POCUS training course was held in March 2017 in Japan. A standardized training curriculum was developed that included online education, live lectures, and hands-on training. The pre-course assessment tools included a written examination to evaluate baseline knowledge and image interpretation skills, and a physician survey to assess confidence in performing specific ultrasound applications. The same assessment tools were administered post-course, along with a course evaluation. All learners were novices and were categorized as trainees or attending physicians. Data were analyzed using two-way analysis of variance. RESULTS: In total, 60 learners attended the course, and 51 learners (85%) completed all tests and surveys. The 51 novice learners included 29 trainees (4 medical students, 9 PGY 1-2 residents, 16 PGY 3-5 residents) and 22 attending physicians (6 PGY 6-10 physicians, and 16 physicians PGY 11 and higher). The mean pre- and post-course test scores of novice trainees improved from 65.5 to 83.9% while novice attending physicians improved from 66.7 to 81.5% (p < 0.001). The post-course physician confidence scores in using ultrasound significantly increased in all skill categories for both groups. Both trainees and attending physicians demonstrated similar improvement in their post-course test scores and confidence with no statistically significant differences between the groups. The course evaluation scores for overall satisfaction and satisfaction with faculty members' teaching skills were 4.5 and 4.6 on a 5-point scale, respectively. CONCLUSIONS: Both novice trainees and attending physicians showed similar improvement in point-of-care ultrasound image interpretation skills and confidence after a brief training course. Although separate training courses have traditionally been developed for attending physicians and trainees, novice learners of point-of-care ultrasound may acquire skills at similar rates, regardless of their ranking as an attending physician or trainee. Future studies are needed to compare the effectiveness of short training courses on image acquisition skills and determine the ideal course design.
