Objective: To investigate an association between the gut microbiome and efficacy of poly(ADP-ribose) polymerase inhibitors (PARPi) in ovarian cancer. Methods: This study conducted fecal microbiome analysis (16S rRNA gene sequencing) and circulating tumor DNA (ctDNA) profiling for ovarian cancer patients who underwent PARPi maintenance therapy. Fecal and blood samples were collected at the baseline and the progressive disease (PD) or last follow-up. The relative abundance of gut microbes and progression-free survival (PFS) were analyzed using linear discriminant analysis of effect size and the Cox proportional hazard model according to BRCA1/2 mutation (BRCA1/2mut) status detected by ctDNA sequencing. Results: Baseline samples were available from 23 BRCA1/2mut-positive patients and 33 BRCA1/2mut-negative patients. The microbes enriched in the baseline samples with long PFS were Bifidobacterium, Roseburia, Dialister, Butyricicoccus, and Bilophila for BRCA1/2mut-positive patients and Phascolarctobacterium for BRCA1/2mut-negative patients. In multivariate analyses dividing patients by the median values of relative abundances, no bacteria were associated with PFS in BRCA1/2mut-positive patients, whereas high Phascolarctobacterium abundances (≥1.11%) was significantly associated with longer PFS in BRCA1/2mut-negative patients (median 14.0 vs. 5.9 months, hazard ratio=0.28; 95% confidence interval=0.11–0.69; p=0.014). In the last samples, the relative abundances of Phascolarctobacterium were significantly higher in patients without PD (n=5) than those with PD (n=15) (median 1.25% vs. 0.06%; p=0.016). Conclusion High fecal composition of Phascolarctobacterium was associated with prolonged PFS in patients with BRCA1/2mut-negative ovarian cancer receiving PARPi therapy. Our results would provide new insights for future research.

The objective of this case report is to introduce a simple technique for simultaneously taking a closed-mouth impression and functionally generated path (FGP) for a full coverage crown restoration. A monolithic zirconia crown was the restoration of choice. An alginate impression of the abutment tooth was taken to fabricate a custom-made closed-mouth impression tray covering the abutment tooth and the adjacent teeth. The tray had an FGP table and an abutment tray in cameo and intaglio surfaces, respectively. The impression was taken with silicone impression material after adjusting the abutment tray and inscribing the FGP using self-curing acrylic resins. Plaster casts were made from the impression, and a zirconia crown was fabricated. The crown was cemented to the abutment tooth with minimal adjustments. This simple technique resulted in a well-fitting crown that accounted for mandibular movements. Using the custom closed-mouth impression tray incorporating an FGP table simultaneously aids in fabricating an accurately fitting restoration that incorporates harmonious mandibular movements using a single impression capture.

Apical ballooning cardiomyopathy (Takotsubo or ampulla cardiomyopathy) is a well-known transient and localized left ventricular (LV) dysfunction characterized by apical severe hypokinesis, typical electrocardiogram (ECG) changes of negative T, and a lack of organic lesions of the coronary arteries which could cause myocardial ischemia leading to segmental asynergy. Here we report on two cases of transient cardiomyopathy showing atypically localized asynergy, which is different from Takotsubo cardiomyopathy. Case 1 was diagnosed as atypical Takotsubo cardiomyopathy, and the current findings suggest case 2 was viral myocarditis. These cases suggest that there exist variant patterns of transient cardiomyopathy, and non-invasive and serial clinical evaluations are important for differential diagnosis in acute and atypical cardiomyopathy.

Magnetic resonance imaging (MRI) for diagnostic evaluation of the breast was performed in 61 patients who visted the Breast Clinic of our hospital and were suspected to have malignant tumors by physical examination and mammography between January and December 1999. In 58 patients undergoing histological diagnostic tests (8 with benignancy and 50 with breast cancer), we compared the imaging characteristics and the time-signal intensity curves acquired by dynamic imaging between benign and malignant lesions, and evaluated the usefulness of analyzing enhancement patterns on contrast MRI. Contrast MRI revealed strong tumor enhancement in all patients; the mean time required for the signal intensity to reach a peak was about 7 min in patients with benign tumors and about 2 min in those with breast cancer. Peripheral ring enhancement was observed in 40 of the 50 patients with breast cancer (80.0%), while such enhancement was not noted in any of the patients with benign tumors.
Although diagnosis of breast disease by imaging has primarily relied on mammography and ultrasonography, the pattern of contrast enhancement on dynamic MRI also appears to be useful for determining the treatment method of breast tumors.

We performed dietary guidances for 15 male elite athletes (23±3 years of age) participating a training program for vigorous endurance run. Nutrient allowances for the athletes were determined by the guidelines of Japanese Dietary Allowances (5 th ed.), considering their physical activities at the highest level IV; total energy 3, 500 kcal, protein 140g, lipid 100g, carbohydrate 510g, calcium 1, 500 mg, iron 25 mg, vitamin A 8, 000 IU, thiamine 4.0 mg, riboflabin 5.0 mg and vitamin C 200 mg per day. We also developed food group allowances for the athletes based on their nutrient allowances and current young-aged Japanese dietary styles ; cereals 400 g, potatoes and starches 60 g, sugars 20 g fats and oils 30g, pulses 120g, meats 150g, fishes and shellfishes 150g, eggs 80g, milks 600g, green and yellow vegetables 300 g, the other vegetables 350 g, fruits 400 g and algae 20 g per day. For the experimental period of 45 days, daily diets adjusted to approximate 120% of the dietary allowances were served to the athletes who were free taking snacks and drinks. Dietary guidances for the athletes were assessed by monitors of their dietary intakes, physical constitution and clinical examinations in blood. Means of the dietary intakes of the athletes were 96-99% of the dietary allowances, determined by a nutritional survey with the 24 hrs recall method. There were less changes in the physical constitution of the athletes before, during and after the experimental period; body weight 57±2 kg and body fat 8.8 ± 2.4%. Values of the clinical marks in the blood of the athletes were maintained normally for a half year including the experimental period; red blood cells 507±9×104 cells/mm3, hemoglobin 15±0.4g/dl and hematocrit 46.6±0.7%.
It is concluded that suitable nutritional guidances and managements for young-aged male vigorous endurance runners lead good in their health and physical maintenances, which may have important consequences for their physical development as elite athletes.
