Decrease of voriconazole trough levels during therapy with enteral nutrition: a case report.

BACKGROUND: Voriconazole (VRCZ) is the first-line therapy for chronic pulmonary aspergillosis and is available in both intravenous and oral formulations. The bioavailability of the oral form is estimated to be over 90% in healthy volunteers. Some drugs are reported to interact with enteral nutrition (EN), but there are few reports about the trough levels of VRCZ during EN therapy. Here, we describe changes in the VRCZ trough levels in a patient receiving continuous EN therapy. CASE PRESENTATION: The patient was a 58-year-old man with esophageal cancer and a history of partial pulmonary resection due to aspergilloma. He was taking oral VRCZ tablets and his VRCZ trough level was about 2 µg/mL before esophageal cancer surgery. Following esophagectomy, VRCZ was restarted on postoperative day 16. Crushed VRCZ tablets were administered via a jejunostomy tube because of swallowing difficulty. He was also receiving EN, which was interrupted only during the administration of VRCZ. When we checked his VRCZ level 5 days after restarting VRCZ, the trough level was 0.80 µg/mL. After increasing the VRCZ dose, reducing EN, and changing the administration route from jejunostomy tube to oral, his trough level increased to 1.87 µg/mL. CONCLUSIONS: A decrease in the VRCZ trough level was observed when VRCZ was administered via a jejunostomy tube while the patient was receiving continuous EN. Careful monitoring of VRCZ levels is needed in such cases.

Improving the Degree of Pubic Arch Post-Yoga Exercise During Pregnancy.

Yoga exercises undertaken during the maternity period may reduce unpleasant symptoms during pregnancy and reduce delivery pain. Flexibility of the hip joint improves the degree of pubic arch created in an open-leg posture and widens the pelvic outlet region, shortening the time required for delivery and facilitating easy delivery. The degree of pubic arch is related to the flexibility of the hip joint. Although many studies have shown the effect of yoga exercise during pregnancy, the effect on the degree of the pubic arch has not been elucidated. To elucidate whether the degree of the pubic arch is improved by yoga exercise during pregnancy, this study enrolled 177 pregnant subjects. The degree of pubic arch pre- and post-yoga exercise was measured using instruments in an open-leg posture (seated with femurs abducted). The mean pubic arch pre- and post-yoga was 122.61 and 127.93 degrees, respectively. The degree of pubic arch post-yoga sessions was significantly increased compared with pre-yoga sessions (p < 0.01). This study showed that yoga exercises during the pregnancy period appear to improve the degree of pubic arch.

Calcitonin levels by ECLIA correlate well with RIA values in higher range but are affected by sex, TgAb, and renal function in lower range.

Calcitonin (CT) is a marker for both initial diagnosis and monitoring of patients with residual or recurrent medullary thyroid carcinoma (MTC). In Japan, serum CT had been measured by radioimmunoassay (RIA) until recently. Electrochemiluminescence immunoassay (ECLIA) became commercially available in 2014, and this technique is now the only method used to examine CT concentration. The purposes of this study were to investigate the correlations between the CT concentration measured with ECLIA (ECLIA-CT) and RIA (RIA-CT) and to explore the clinical characteristics of patients with elevated ECLIA-CT. CT concentrations of 348 sera samples from 334 patients with various thyroid disorders including nine MTC were measured using both assays. The correlation analysis revealed an excellent correlation between ECLIA-CT and RIA-CT among the cases with CT level >150 pg/mL by both assays (rs = 0.991, p < 0.001). However, 63% of all samples exhibited undetectable ECLIA-CT, while their RIA-CTs were measured between 15 and 152 pg/mL. The ECLIA-CTs in all patients who underwent total thyroidectomy for non-MTC showed low concentrations. High ECLIA-CT was observed in patients with MTC or pancreas neuroendocrine tumor. ECLIA-CT was also increased in 14 other male patients with non-MTC, including four with renal failure. Multivariate logistic regression analysis showed that male sex, negative TgAb, and lower estimated glomerular filtration rate were independent factors to predict detectable ECLIA-CT (≥0.500 pg/mL). These results indicate that ECLIA-CT correlates well with RIA-CT in higher range and is affected by sex, TgAb, and renal function.

Diagnosis of mild cognitive impairment using multiple neuroimaging modalities in addition to the Mini-Mental State Examination.

AIM: This prospective study investigated the additional utility of combining multiple imaging modalities with the Mini-Mental State Examination (MMSE) in discriminating individuals with mild cognitive impairment (MCI) from cognitively normal individuals. METHODS: A total of 103 individuals with amnestic MCI and normal cognitive function were recruited from outpatients; they underwent examination using the MMSE, magnetic resonance imaging, 18 F-fluorodeoxyglucose positron emission tomography and 11 C-Pittsburgh compound B positron emission tomography. Binary logistic regression with receiver operator characteristic analysis was used to assess the combination of the abovementioned single or multiple imaging modalities with the MMSE. Eight models were constructed, and their area under the curve values and misclassification rates in discriminating individuals with amnestic MCI from cognitively normal individuals were evaluated. RESULTS: The addition of each of the imaging modalities improved the discrimination accuracy over that of the MMSE alone; the accuracy obtained with the addition of 18 F-fluorodeoxyglucose positron emission tomography was the highest. The best model with the highest accuracy included a combination of all the imaging modalities in addition to the MMSE (area under the curve value 0.902). CONCLUSIONS: The combination of all the imaging modalities in addition to the MMSE could facilitate more accurate diagnosis of amnestic MCI. Of the individual imaging modalities, the highest accuracy resulted from the addition of 18 F-fluorodeoxyglucose positron emission tomography to the MMSE. Geriatr Gerontol Int 2019; 19: 1193-1197.

Comparison of Geriatric Nutritional Risk Index scores on physical performance among elderly patients with chronic obstructive pulmonary disease.

OBJECTIVES: The Geriatric Nutritional Risk Index (GNRI) is a new prognostic indicator for nutritional status-related complications and mortality among the elderly. Here we aimed to compare 6-min walk distance (6MWD) between high and low GNRI groups for patients with COPD. METHODS: We enrolled 63 elderly men with COPD. These subjects were divided into two groups based on their GNRI scores: high GNRI group (≥92 points; n = 44) and low GNRI group (n = 19); we compared 6MWD between these groups. RESULTS: The subjects' characteristics between the high and the low GNRI groups were similar, except for BMI and serum albumin levels. 6MWD were significantly lower in the low GNRI group (279.5 ± 112.3 m versus 211.1 ± 125.3 m; p = 0.03). CONCLUSIONS: The GNRI has a more close relation with exercise tolerance and may be a useful nutritional assessment scale for elderly patients with COPD.

Long-term Effect of Home Nursing Intervention on Cost and Healthcare Utilization for Patients with Chronic Obstructive Pulmonary Disease: A Retrospective Observational Study.

PURPOSE: The present study aimed to examine the long-term effects of a home nursing intervention on healthcare utilization and costs among patients with chronic obstructive pulmonary disease (COPD). DESIGN: A 3-year retrospective study. METHODS: Eleven COPD patients who had received home nursing intervention after hospital discharge were enrolled. We retrospectively investigated their healthcare utilization and costs for 1 year before the intervention and during 2 years of the intervention. FINDINGS: The number and length of hospitalizations decreased gradually from the pre-intervention period through the second year. The number of hospital and home nursing visits increased from the pre-intervention period through the first and second years. The hospitalization costs were decreased by approximately half from the pre-intervention period through the first year and from the first year through the second year. The total medical cost did not change significantly. CONCLUSIONS AND CLINICAL RELEVANCE: Our home nursing intervention decreased the number and length of hospitalizations and the hospitalization costs; however, it did not affect the total medical cost. It is possible that the continuation of home nursing interventions may decrease the number of hospitalizations, number of home nursing visits, and the total medical cost by maintaining the health condition of patients.

Correlation between antizyme 1 and differentiation of vascular smooth muscle cells cultured in honeycomb-like type-I collagen matrix.

Vascular smooth muscle cells (SMC) are able to proliferate when cultured on plates, but become differentiated when maintained in three-dimensional type I collagen matrices (honeycombs). SMC grown in honeycombs contained a low level of polyamines due to the presence of antizyme 1 (AZ1), a negative regulator of ornithine decarboxylase (ODC) and of polyamine uptake. To clarify the role of AZ1 in differentiation of SMC in honeycombs, an ODC gene was stably transfected into SMC (ODC-SMC). Although proliferation of ODC-SMC on plates was accelerated together with an increase in phosphorylated focal adhesion kinase (FAK) and a decrease in α-actin and myosin, maker proteins of differentiation, growth of ODC-SMC ceased in honeycombs similarly to normal SMC with a low level of phosphorylated FAK and a high level of α-actin and myosin. AZ1 expression in ODC-SMC on plates was low, but that in honeycombs was high. Antizyme in ODC-SMC in honeycombs not only decreased the level of ODC but also inhibited polyamine uptake activity. These results taken together suggest that low levels of polyamines caused by AZ1 in SMC in honeycombs inhibit phosphorylation of FAK and enhance expression of α-actin and myosin, resulting in differentiation through inhibition of focal adhesions.

Clinical features of the 2009 swine-origin influenza A (H1N1) outbreak in Japan.

To clarify the clinical symptoms of the influenza A virus during the 2009 pandemic influenza outbreak, we describe the clinical features of outpatients diagnosed with type A influenza by use of the rapid influenza diagnostic test (RIDT) from September to December 2009. Questionnaires were used to collect prospective data on 1,122 cases with influenza-like illness at our medical institutions. The independent predictors of influenza A virus were identified on the basis of demographic features and the clinical symptoms of the patients who tested positive for influenza A virus in the RIDT test. Of the 1,122 cases tested, 389 (34.7%) were positive for the influenza A virus. The median age of the influenza-positive patients was 14, and 58.9% of the patients were male. The symptoms fever, cough, rhinorrhea, and headache were statistically dominant. A history of recent contact with persons suffering from influenza or influenza-like illness at home, school, or in the workplace was significantly more common in the positive group than in the negative group. Pneumonia was observed in 2 (0.5%) of the positive patients, but the symptoms were only severe enough to require hospitalization in 1 of the 2. No deaths were observed among the 389 RIDT-positive patients. Although the spread of influenza A virus was both rapid and extensive, mainly among children under the age of 18, it seemed to be mild. Appropriate interpretation of the RIDT on the basis of recent clinical information, and early treatment with antiviral drugs might help to prevent severe illness from influenza pandemics in the future.

[A case of effective treatment of oral TS-1 and intravenous MMC administration for multiple metastases of gastric cancer].

A 49-year old man underwent distal gastrectomy (D3) for circumferential type 3 cancer at the gastric antrum and cholecystectomy in September 2002. During the surgery, multiple metastases were observed predominantly in the left lobe of the liver, and lateral segmentectomy was performed as non-curative (curability-C) resection leaving the small metastases in the right lobe of the liver. Based on the results of chemo-sensitivity tests (5-FU 15.0%, CDDP 34.0%, MMC 35.3%, TXT 0.0%), we started to administer TS-1 (100 mg/day for 4 weeks followed by a 2-week rest interval) and MMC (10 mg/body on day 1). Due to leukocytopenia, the regimen was changed to TS-1 (100 mg/day for 4 weeks followed by a 2-week rest interval) and MMC (4 mg/body every other week [day 1, 14]) from the second course. Levels of tumor markers dropped and liver metastatic lesions remarkably decreased in size by CT after the third course. In conclusion, a combination of TS-1/MMC may be regarded as one option for postoperative adjuvant chemotherapy for outpatients.

Correlation between survivin mRNA expression and lymph node metastasis in gastric cancer.

BACKGROUND: Correlations between the malignant potential and prognosis of cancer and abnormal control mechanisms of apoptosis have been discovered in a variety of cancers. Survivin is a member of the inhibiting apoptosis protein family that is abundant in embryonic and carcinoma tissues. We measured the expression of survivin mRNA in gastric cancer to determine whether levels of survivin mRNA expression could serve as an index of malignancy. METHODS: Expression of survivin mRNA was measured in samples of both gastric cancer and noncancerous tissue from 107 patients. Survivin mRNA was detected by the real-time polymerase chain reaction (PCR) method, and then the relationship between the survivin mRNA level and histological diagnosis was analyzed. RESULTS: Expression of survivin mRNA was observed in 105 of 107 cancerous tissues and in 101 of 107 noncancerous tissues. The Mean value of survivin mRNA expression in cancerous tissue was 5.18 +/- 1.30, significantly higher ( P < 0.01) than that in noncancerous tissue, at 4.21 +/- 1.48. No significant differences were found in the values of survivin mRNA expression according to histological classification or according to increasing depth of tumor invasion. However, survivin mRNA expression was significantly higher ( P < 0.01) in patients displaying lymph node metastasis (5.48 +/- 1.01) than in patients without the metastasis (4.70 +/- 1.55). CONCLUSIONS: These results indicate that increased survivin mRNA expression begins in the early stages of gastric carcinogenesis. Moreover, the level of survivin mRNA expression may indicate the potential for lymph node metastasis in patients with gastric cancer. Correlations between the malignant potential and prognosis of cancer and abnormal control mechanisms of apoptosis have been discovered in a variety of cancers. Survivin is a member of the inhibiting apoptosis protein family that is abundant in embryonic and carcinoma tissues. We measured the expression of survivin mRNA in gastric cancer to determine whether levels of survivin mRNA expression could serve as an index of malignancy.
