A 59-year-old woman, who had a history of acute coronary syndrome (ACS) but without obstructive coronary lesions 2 years previously, presented with vertigo. MRI revealed a left cerebellar embolism. TEE detected a mobile aortic valve tumor, suggesting a papillary fibroelastoma (PFE). Reviewing previous echocardiograms, it was discovered that the tumor was present at the time of the ACS event. At surgery, the PFE was present on the right coronary cusp. When the aortic valve was opened, it was found that the tumor was obstructing the right coronary artery (RCA) ostium. ACS was probably caused by PFE's dynamic obstruction of the RCA ostium.

Neuromuscular electrical stimulation (NMES) is widely used for improving muscle strength, preventing muscle atrophy, and decreasing pain. Recently, NMES has become a substitute for exercise therapy for metabolism improvement and functional capacity improvement. However, NMES has several disadvantages. First, slow-twitch muscle contractions are insufficient because the recruitment pattern of NMES does not obey Henneman's size principle. Second, when using surface electrodes, it is difficult to contract deep skeletal muscles at the application site. Third, electrical stimulation causes discomfort. Therefore, we devised a simultaneous combination of NMES and voluntary muscle contractions to overcome the weak points of NMES. A hybrid training system (HTS) that resists the motion of a volitionally contracting agonist muscle with force generated by its electrically stimulated antagonist was developed as a technique to combine the application of NMES and volitional contractions. This motion sensor makes it possible to simultaneously combine voluntary movements with NMES. Our HTS synchronizes with voluntary movements, enhancing safety and reducing discomfort. This HTS enhances the exercise effect of even simple exercise. So far, our HTS has been reported to be effective for muscle strength enhancement, prevention of muscle atrophy, improvement of physical function, pain relief, enhancement of physical fitness, and improvement of metabolic function. HTS are expected to be useful methods in environments where sufficient exercise load is not available or for individuals with low exercise tolerance.

Background: Very few studies have examined the association between contrast-enhanced computed tomography (CT) findings observed in portal venous gas (PVG) and pneumatosis intestinalis (PI) and the underlying diseases in these conditions.

Objectives: In this study, we analyzed this association and report the findings for predicting mortality.

Materials and methods: Overall, 50 patients diagnosed with PVG or PI, observed on contrast-enhanced CT, underwent treatment at our hospital. Based on the underlying disease, we divided the patients into three groups, those with ischemic disease, infectious disease, or gastrointestinal dilatation. Furthermore, cases that underwent surgical treatment or needed surgery but were inoperable were assigned to the high risk group (n=16) and patients who received conservative treatment were assigned to the low risk group (n=34). We reviewed the patients' medical charts, laboratory data, and CT images retrospectively, and analyzed the relationship between CT findings, underlying disease, and association with the high risk or low risk group in each case.

Results: Poor enhancement of the intestinal wall, mesenteric fat stranding, extrahepatic PVG, advanced age, and renal disease were significantly associated with ischemic disease (p=0.02, p=0.02, p=0.005, p=0.008 and p=0.049, respectively). PI alone was strongly associated with gastrointestinal dilatation (p=0.009). Patients in the low risk group had more favorable outcomes with conservative treatment. In multivariate analysis, extrahepatic PVG was the only factor associated with the high risk group (p=0.002).

Conclusion: Extrahepatic PVG associated with ischemic disease was the strongest predictive factor of mortality. Other CT findings, though useful in diagnosing the underlying disease, were not significant predictive factors.

Due to bicuspid aortic valve aortic stenosis, a 78-year-old man with a history of esophagectomy and presternal gastric tube reconstruction required aortic valve replacement (AVR). AVR with a bioprosthetic valve was performed through a right parasternal thoracotomy. Despite the unfavorable conditions for conventional median sternotomy, AVR was successfully performed through an alternate approach. The right parasternal approach was excellent for AVR in patients with presternal gastric tube reconstruction for esophageal cancer (EC).

Objectives: This study aimed to examine the effects of cognitive tasks during walking with perturbation on the cerebral blood flow.

Methods: The subjects were a total of 20 persons, consisting of 12 healthy adults aged 21-47 years (adult group) and 8 retirement home residents aged 67-85 years who led an independent daily life and could walk independently (elderly group). Oxyhemoglobin was measured using wireless functional near-infrared spectroscopy (fNIRS). An analysis was conducted using the Wilcoxon rank sum test to compare the variation of oxyhemoglobin between walking with perturbation (WP) and walking with perturbation and cognitive tasks (WPC) in each group. In addition, we compared the variation of oxyhemoglobin between groups by analysis of covariance adjusting for the value of WP.

Results: In the adult group, the left and right oxyhemoglobin significantly increased under WPC (p=0.0122, 0.0015, respectively). On the other hand, in the elderly group, the right and left oxyhemoglobin did not significantly change under WPC.

Conclusions: These results suggest that the effect of a cognitive task during unstable walking conditions differs between healthy adults and elderly persons, and that this may be important when considering postural control strategies, especially in the elderly.

Background: Treatment with antiviral drugs for non-severe, early time from onset, adult outpatients with Coronavirus Disease 2019 (COVID-19) had not been established in 2021. However, some new variants of SARS-CoV-2 had caused rapid exacerbation and hospitalization among non-elderly outpatients with COVID-19, contributing to widespread crises within healthcare systems.

Methods: From July to October 2021, we urgently assessed a therapeutic program using oral colchicine (1.0 mg loading dose, followed approximately half a day later by 0.5 mg twice daily for 5 days, and then 0.5 mg once daily for 4 days) and low-dose aspirin (100 mg once daily for 10 days), for non-elderly, non-severe, early time from onset, adult outpatients with COVID-19. To verify its effectiveness, we set loxoprofen as a control arm, and com parison of these two arms was performed. The primary outcomes were hospitalization, criticality, and death rates.

Results: Thirty-eight patients (23 receiving colchicine and low-dose aspirin [CA]; 15 receiving loxoprofen [LO]) were evaluated. Hospitalization rate was lower in the CA group (1/23; 4.3%) than in the LO group (2/15; 13.3%); however, no significant difference was found between the two groups (p=0.34). No critical cases, deaths, or severe adverse events were found in either group.

Conclusions: Our CA regimen did not show superiority over LO treatment. However, our clinical experience should be recorded as part of community health care activities carried out in Kurume City against the unprece dented COVID-19 pandemic.

Background: Lower gastrointestinal tract stenosis is commonly diagnosed and is typically treated with surgery or endoscopic balloon dilation (EBD). Radial incision and cutting (RIC) is a novel treatment approach that has several benefits compared with EBD and surgery. Although RIC has demonstrated a high technical success rate and has been shown to improve subjective symptoms, previous studies revealed that restenosis after RIC remain unsolved. Herein, we report the design of a prospective, multicenter, single-arm, interventional, phase II trial to evaluate the safety of local triamcinolone acetonide (TA) administration and its feasibility in preventing restenosis after RIC for lower gastrointestinal tract stenosis.

Methods: The major inclusion criteria are age 20-80 years and the presence of benign stenosis in the lower gastrointestinal tract accessible by colonoscope. We will perform RIC followed by local administration of TA to 20 participants. The primary outcome is the safety of local TA administration, which will be assessed by determining the frequency of adverse events of special interest. The secondary outcomes are the technical success rate of RIC, duration of procedure, improvement in subjective symptoms, and duration of hospitalization. The outcomes, improvement in subjective symptoms, and long-term results will be evaluated using descriptive statistics, Student's t-test, and Kaplan-Meier curve, respectively.

Discussion: This explorative study will provide useful information regarding the safety of TA administration after RIC, which may contribute to further investigations.

Aim: In autism spectrum disorder (ASD), abnormal sensory processing patterns are observed in various sensory modalities, including visual, auditory, touch, olfactory, taste, vestibular, and proprioceptive senses. Few studies have examined the relationship between sensory processing patterns and emotions, or their effects on daily life. We investigated the relationship between sensory processing patterns and emotional/behavioral problems in children with ASD.

Participants and methods: A retrospective chart review was conducted. Forty-three children with ASD (33 boys, 10 girls, median age 9 years) in the outpatient clinic of a psychiatric hospital participated; their parent (s) were invited to complete the Sensory Profile 2 (SP2) and the Child Behavior Checklist (CBCL) questionnaires. The participants' teachers were invited to complete the Teacher's Report Form (TRF).

Results: In the correlation analyses, each of the four quadrants of the SP2 (low registration, sensory seeking, hypersensitivity, and sensory avoiding) had significant positive correlations with different types of emotional and behavioral problems measured by the CBCL. Focusing on emotion, 'anxious/depressed' was correlated with low registration (r = 0.41) and sensory avoiding (r = 0.60), while 'withdrawal/depressed' was correlated with sensory avoiding (r = 0.46). Only one significant correlation was revealed between the SP2 and the TRF.

Conclusion: Our results suggest a link between sensory processing patterns and emotional/behavioral problems. In school settings, the relationship between sensory processing patterns and emotional/behavioral problems may be easily overlooked.

Mean platelet volume (MPV) can provide important information about the course and prognosis of many diseases. MPV is an early indicator of platelet activation, which has an important role in the pathogenesis of thrombosis. In this study, we aimed to investigate whether MPV was a predictive marker for the development of thrombosis in hospitalized patients with COVID-19 infection. Fifty-seven patients whose courses were followed after the diagnosis of COVID-19 infection using a polymerase chain reaction test during the pandemic were included in the study. Our results demonstrated that there was a negative correlation between platelet count and MPV (r=0.470, p≤ 0.01), and there was a positive correlation between Platelet Distribution Width (PDW) and MPV (r=0,933, p≤ 0.01), but no significant correlation was found between the other variables and MPV.
