RESUMO
Although pharmacist counseling assumes an important role in the clinical setting, oncology pharmacy practitioners worldwide currently lack adequate guidance. This study aimed to identify the determinants and causal relationships that affect quality of life (QOL) in breast cancer patients before adjuvant systemic therapy for improving pharmacist counseling and guidance. This study analyzed 93 postoperative patients with breast cancer before pharmacist counseling for adjuvant systemic therapy. Patients were asked to complete questionnaires to assess QOL (the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire C30 [EORTC QLQ-C30] and its breast cancer module [EORTC QLQ-BR23]) before pharmacist counseling. We analyzed factors affecting QOL by stepwise multiple linear regression analysis and evaluated causal association using path analysis. In the multiple linear regression model using variables selected by stepwise analysis, the factors affecting global health status (GHS)/QOL included fatigue, emotional functioning, systemic therapy side effects, future perspectives, and appetite loss. In the path analysis model, GHS/QOL were strongly influenced by fatigue directly; and emotional functioning, directly and indirectly via other factors. Our results indicated that fatigue and emotional functioning are strong factors affecting QOL. These factors may be able to predict poor QOL before initiating adjuvant systemic therapy. Thus, our findings suggest that these factors may be potentially useful for pharmacist counseling at the beginning of adjuvant systemic therapy.

Seasonal change in the vertical distribution of ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB) in temperate forest soil was examined from March 2008 to January 2009 by quantitative PCR of the amoA genes. Abundances of AOA amoA genes (ranging from 2.0×10(8) to 1.2×10(9) copies per gram dry soil) were significantly higher than those of AOB amoA genes (1.9×10(5) to 1.7×10(7) copies). A significant increase in AOB was observed at a depth of 0-5 cm in July when net nitrification was also high in the top soil, while AOA increased significantly at depths of 5-10 cm, 10-15 cm, and over 15 cm in July. Sequencing of the crenarchaeotal amoA gene revealed shifts in major AOA components along the soil depth profile and among sampling dates. Betaproteobacterial amoA clone libraries at 0-5 cm in March, May, and July were dominated by Nitrosospira clusters 1 and 4. A microcosm experiment at 0-5 cm in July revealed a decrease in the ratio of AOA/AOB amoA genes in microcosms. These results suggest that AOB play an important role in net nitrification in the top layer in temperate forest soil.

The present study describes the occurrence of a unique archaeal ammonia monooxygenase alpha subunit (amoA) gene in nitrifying acid-sulfate soil microcosms at pH 3.5. The soil was collected from an abandoned paddy field in Thailand. Microcosms were incubated in the dark at 30°C for 372 days with the following three treatments: addition of ammonium sulfate solution once a month (I) or once a week (II), and addition of only sterilized water (III). A quantitative PCR analysis revealed an increase in abundance of the archaeal amoA gene in microcosm soils in which nitrate concentrations increased after incubation. A phylogenetic analysis indicated a predominance of the novel gene, and a predominance of a betaproteobacterial amoA gene affiliated with the genus Nitrosospira. A 16S rRNA gene-based PCR assay revealed that crenarchaeotic Group I.1d was predominant among the Crenarchaeota in microcosms. These results suggest the presence of ammonia-oxidizing archaea corresponding to the unique amoA lineage in nitrifying acid-sulfate soil microcosms at pH 3.5.
