Eosinophilic inflammation in combination with immunoglobulin E (IgE) production is a characteristic feature of atopic dermatitis. Although activated T-helper type (Th) 2 cells play critical roles in the local accumulation and activation of eosinophils, whether they induce eosinophilic skin inflammation, independent of the IgE-mediated pathway has been unclear. To address the functional role of T cells in allergic skin diseases, we herein transferred Th1/Th2-differentiated or naive DO11.10 T cells into unprimed BALB/c mice. Ovalbumin-specific Th2 cells, as well as eosinophils, accumulated in the skin upon antigen challenge, despite the absence of antigen-specific IgE. Neither antigen-specific Th1 nor naive T cells induced eosinophil accumulation, although Th1 cells by themselves migrated into the skin. Interleukin (IL)-4, IL-5, and eotaxin were specifically produced in the skin of antigen-challenged, Th2 cell-transferred mice, whereas interferon (IFN)-γ and regulated on activation, normal T cell expressed and secreted (RANTES) were preferentially produced in Th1 cells-transferred mice. Production of monocyte chemoattractant protein (MCP)-1 and MCP-3 was enhanced by both Th1 and Th2 cells. The accumulation of eosinophils and Th2 cells in the skin was suppressed by both dexamethasone and FK506, indicating an essential role of Th2 cells in eosinophil recruitment. We conclude that Th2 cells can induce eosinophilic infiltration into the skin in the absence of antigen-specific IgE.

Background:
The association of the combination of body mass index (BMI) and weight change at admission with prognoses in patients with heart failure (HF) is unclear. Therefore, we investigated whether BMI and weight changes at admission affect mortality in patients with HF.
Methods:
This retrospective cohort study lasted 99 months, starting in April 2014, and included 4,862 patients with HF from a Japanese real-world database. Cubic and thin-plate smoothing spline analyses were performed to investigate the association of BMI and weight changes with mortality. The percentage weight change was calculated every 6 months. The study outcome was the presence or absence of death.
Results:
The patients’ mean age was 81.5±9.6 years, and 1,239 (25.5%) patients died. Cubic spline analysis revealed a negative correlation of BMI with mortality hazard ratio (HR) (BMI of 18.5 kg/m2 and 25 kg/m2; HR=1.3 [1.2–1.4] and 0.8 [0.7–0.9], respectively). Cubic spline analysis of weight change showed that weight loss tended to increase the mortality HR (each 6% decrease in weight change rate was associated with a 1.1 times higher mortality risk (95% CI [1.0–1.2]) Thin-plate smoothing spline analysis showed that the odds ratio (OR) negatively correlated with BMI (1-year mortality: BMI of 18.5 kg/m2, 22 kg/m2, and 25 kg/m2; OR at 0% weight change=1.5, 1.0, and 0.7, respectively; 2-year mortality: BMI=18.5 kg/m2, 22 kg/m2, and 25 kg/m2; OR at 0% weight change=1.4, 0.9, and 0.7, respectively).
Conclusion
A low BMI in patients with HF was associated with a higher risk of mortality. Weight loss in patients, regardless of BMI, was associated with a higher OR for mortality.

This study aimed to characterize physical function and functional capacity related to low muscle mass and sarcopenia in older women with low bone mass. In the study, 122 older women with bone loss were included and divided into three groups according to the presence or absence of muscle loss and sarcopenia; bone loss only, bone loss and muscle loss, and bone loss and sarcopenia groups. Multinomial logistic regression analysis was conducted using the three groups as dependent variables. Body mass index (BMI) (odds ratio; 0.566, 95% confidence interval; 0.431-0.742), Kihon checklist of “motor function” (odds ratio; 2.230, 95% confidence interval; 1.179-4.217), and “homebound” (odds ratio; 5.123, 95% confidence interval; 1.122-23.391) were extracted as relevant factors in the bone loss and sarcopenia group. In addition to low BMI, sarcopenia in older women with reduced bone mass is associated with lower “motor function” and “homebound” functional capacity.

Drug dispensing is a statutory and designated duty of a pharmacist. We aimed to examine the changes in the nature of drug dispensing using a text mining method. Our corpus consisted of text documents from “Chozai Shishin”, the most standard manual for dispensing drugs in Japan, Editions 1 to 13 (Japan Pharmaceutical Association), and we used the KH Coder software for text mining. We constructed networks showing the association between frequent word co-occurrence and edition number, and co-occurrence relations for frequent words in each edition. We found that “patient” superseded “dispensing” as a frequent term over time. “Dispensing” was another frequent term with a highly centralized node in each edition. Accordingly, we targeted the term “dispensing” for network analysis to depict its co-occurrence relations. We found that the range of related words for “dispensing” broadened from “preparation” and “compounding” to include “patient adherence instructions”, “assessment”, “medical treatment”, and “information provision”. Accordingly, we concluded that the content of “dispensing”, which is a pharmacist’s duty, has expanded from the duties of “dispensing drugs” to include “responding to patients” within the definition of “dispensing”, and we were able to present this finding as objective data by using the mechanical method known as text mining.

Intra-arterial chemoradiotherapy for advanced oral cancer has recently been reported and can preserve the form and function of the tongue by avoiding surgery at the primary site. We report here a case of advanced tongue cancer treated with intra-arterial chemoradiotherapy that preserved phonation and swallowing function. A 71-year-old man presented with an ulcerative mass, 43×28 mm in size, extending from the left lingual margin to the base of the tongue. The pathological diagnosis was squamous cell carcinoma based on biopsy results, and the clinical diagnosis was left lingual carcinoma (cT3N0M0, stage III) based on imaging findings. A polyurethane catheter was inserted into the left lingual artery, and intra-arterial chemotherapy was administered using docetaxel (15 mg/m2/week, total dose 60 mg/m2) and cisplatin (5 mg/m2/ day, total dose 125 mg/m2) with concurrent radiotherapy (2 Gy/day, total dose 50 Gy). Posttreatment biopsy results showed no tumor cells, and complete response was achieved, thus avoiding surgical resection of the primary site. Six years after completing treatment, the patient remains in good health with no recurrence, metastasis, phonation problems, or dysphagia.
