Coffee and metabolic phenotypes: A cross-sectional analysis of the Japan multi-institutional collaborative cohort (J-MICC) study.

BACKGROUND AND AIMS: To date, the relationship between coffee consumption and metabolic phenotypes has hardly been investigated and remains controversial. Therefore, the aim of this cross-sectional study is to examine the associations between coffee consumption and metabolic phenotypes in a Japanese population. METHODS AND RESULTS: We analyzed the data of 26,363 subjects (aged 35-69 years) in the baseline survey of the Japan Multi-Institutional Collaborative Cohort Study. Coffee consumption was assessed using a questionnaire. Metabolic Syndrome (MetS) was defined according to the Joint Interim Statement Criteria of 2009, using body mass index (BMI) instead of waist circumference. Subjects stratified by the presence or absence of obesity (normal weight: BMI <25 kg/m2; obesity: BMI ≥25 kg/m2) were classified by the number of MetS components (metabolically healthy: no components; metabolically unhealthy: one or more components) other than BMI. In multiple logistic regression analyses adjusted for sex, age, and other potential confounders, high coffee consumption (≥3 cups/day) was associated with a lower prevalence of MetS and metabolically unhealthy phenotypes both in normal weight (OR 0.83, 95% CI 0.76-0.90) and obese subjects (OR 0.83, 95% CI 0.69-0.99). Filtered/instant coffee consumption was inversely associated with the prevalence of MetS and metabolically unhealthy phenotypes, whereas canned/bottled/packed coffee consumption was not. CONCLUSION: The present results suggest that high coffee consumption, particularly filtered/instant coffee, is inversely associated with the prevalence of metabolically unhealthy phenotypes in both normal weight and obese Japanese adults.

[A Case of Long-Term Survival of a Patient with Liver Metastasis of Colon Cancer and Suspected Inferior Vena Cava Invasion].

A 58-year-old woman was diagnosed with a sigmoid colon cancer and synchronous liver metastasis. Because an obstruction of the sigmoid colon was identified, the patient underwent sigmoidectomy. Computed tomography(CT)findings suggested possible vena cava and hepatic vein invasion. Therefore, the decision was made to offer systemic chemotherapy. The patient underwent 6 courses of chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6). After 4 courses of chemotherapy, CT scans showed a significant reduction of the liver metastasis (reduction rate of 5 0%; a partial response) and demonstrated improved exclusion of the inferior vena cava and hepatic vein. After 6 courses of chemotherapy, we performed right trisegmentectomy of the liver and resection of the inferior vena cava and diaphragm. Postoperative pathological findings revealed negative margins, and no invasion of the inferior vena cava. The pathological response grade of the tumor after chemotherapy was determined to be Grade 2. Adjuvant chemotherapy was not performed because of the patient 's poor performance status. The patient was alive with no recurrence 8 years after resection of the liver metastasis.

Reduced perfusion reserve in Leukoaraiosis demonstrated using acetazolamide challenge 123I-IMP SPECT.

OBJECTIVE: We examined the relationship between the perfusion reserve as measured by acetazolamide (ACZ)-challenge N-isopropyl-I-123-p-iodoamphetamine (IMP)-single-photon emission computed tomography (SPECT) and the degree of leukoaraiosis (LA) as estimated using magnetic resonance imaging. METHODS: In 51 patients receiving IMP-SPECT with the resting state and ACZ challenge, the unaffected cerebral hemispheres were included in the present study. Mean cerebral blood flow (CBF) in the resting state and ACZ reactivity were acquired. Absolute CBF value and ACZ reactivity were compared among patients with LA grades 0, 1, and 2. The relationship between mean age and LA grade was also assessed. RESULTS: No significant difference in the absolute CBF value in the resting state was observed among the 3 LA groups. Although vasoreactivity in LA grade 0 did not differ from that in grade 1, vasoreactivity in LA grade 2 was significantly lower (P < 0.05) than that in grades 0 or 1. CONCLUSIONS: The perfusion reserve is impaired in advanced LA.
