BECOMING BICULTURAL: CHINESE AMERICAN WOMEN AND THEIR DEVELOPMENT

Ethnic and racial diversity in the United States has led to increasing interest in research on biculturalism, yet the meaning and underlying processes of biculturalism in the context of development in young adults are not well understood. Fifteen interviews were conducted with second-generation Chinese American women to explore how being bicultural fit into their lives. Data analysis yielded a developmental map that reflected their experiences throughout life as minority women. Findings suggest that biculturalism is more than being functionally competent in two cultures, it is both a behavioral and psychological orientation in life. From the findings of this study, we have increased our knowledge of Asian American women's development and provided a foundation for nursing research with minority women.     

Three adult cases with Corynebacterium propinquum respiratory infections in a community hospital

Corynebacterium propinquum, which is included in Corynebacterium group ANF-3, exists as a commensal in the oral flora. This organism has not yet been fully recognized as a respiratory pathogen. We previously reported that the first case with respiratory infection caused by C. propinquum. On the other hand, Corynebacterium pseudodiphtheriticum is recognized as a causative organism in respiratory infections. Recently we experienced two cases with C. propinquum respiratory infections in our hospital. Three types of the onset such as a community-acquired infection, a hospital-acquired infection, and a nursing home acquired infections were observed. Our analysis indicated that gram staining of the purulent sputum is an essential tool to evaluate whether C. propinquum is a respiratory pathogen or not, because this organism is a commensal bacteria.     

21-hydroxylase deficiency associated with adrenal tumor: case report of two brothers

Described herein are two brothers with 21-hydroxylase deficiency (21-OHD) associated with adrenal tumors, and these possible mechanisms are discussed. A 34-year-old male was admitted on Jan. 9, 1984 because of an enlarged and tender left breast. Physical examination revealed short stature (152 cm, 76.5 kg), gynecomastia and shortening of metacarpal bone. His testes were small (2.6 X 1.6 X 1.9 cm). Urinary excretion of 17-OHCS was within normal range (5.9 mg/day), but those of 17-KS, 17-KGS and pregnanetriol were markedly increased (44.4, 110 and 22.6 mg/day, respectively). Plasma concentrations of progesterone and ACTH and urinary excretions of estrone, estradiol and estriol were also increased. Urinary excretions of 17-KS were decreased to 11.7 mg/day and 17-KGS to 22.3 mg/day after the ingestion of 2 mg/day dexamethasone for two days. The computed tomography and a scintigraphy with 131I-Adosterol revealed a tumor in the left adrenal gland, and the adrenal arteriography revealed a neovascularity and a tumor stain in the tumor. These data indicated that the patient was suffering from both 21-OHD and the left adrenal tumor. At this point, adenoma or adenocarcinoma of the adrenal gland was suspected. The left adrenal tumor (85 g) was resected on April 10, 1984, and the pathological diagnosis was adrenal adenoma. The patient's endocrinological abnormalities, however, did not improve after the operation. Urinary excretions of 17-KS and KGS were increased to 57.9 and 108.5 mg/day, respectively, in the patient's elder brother, and 63.3 and 127.9 mg/day, respectively, in his younger brother, indicating that they also had 21-OHD. Interestingly, an adrenal tumor was diagnosed by abdominal computed tomography in the elder brother who had the same HLA typing as the present case. The three brothers had 21-OHD, and two of them had both 21-OHD and adrenal tumor. To our knowledge, this is the first report documenting the co-existence of adrenal tumors in brothers with 21-OHD. This suggests that adenoma can be one of the complications of 21-OHD, probably due to the chronic stimulation by ACTH, and that a possible linkage to HLA may exist in such cases.     

A case of factor X (FX) deficiency due to novel mutation V196M,FX Hofu

The patient, a 20-year-old male, was found to have a slightly prolonged prothrombin time (PT). No episodes of bleeding were noted. The measurement of coagulation factors revealed that the level of factor X (FX) activity was solely deficient, 51% (normal range: 70–130% ), and that of FX antigen was 100%. Analysis of the entire FX gene revealed the novel missense mutation of GTG to ATG, resulting in the substitution of the 196th amino acid valine → methionine. The mother and younger brother had a normal PT time and expressed no episode of bleeding. The mother exhibited a normal level of FX activity and antigen; however the younger brother showed a slight decrease in both the parameters. This mutation was not observed in the mother and younger brother. Polymorphism is not observed at this point in healthy persons. The present novel FX mutation was named FX Hofu.     

Influence of topical steroids on intraocular pressure in patients with atopic dermatitis

Background

Topical corticosteroids (TCS) can induce adverse effects, such as skin atrophy. Although TCS can cause increases in intraocular pressure (IOP), the effects of daily TCS use on IOP have not been fully elucidated. We evaluated the clinical doses of TCS and the change in the IOP during the daily treatment of atopic dermatitis (AD).

Techniques of biliary drainage for acute cholecystitis: Tokyo Guidelines

The principal management of acute cholecystitis is early cholecystectomy. However, percutaneous transhepatic gallbladder drainage (PTGBD) may be preferable for patients with moderate (grade II) or severe (grade III) acute cholecystitis. For patients with moderate (grade II) disease, PTGBD should be applied only when they do not respond to conservative treatment. For patients with severe (grade III) disease, PTGBD is recommended with intensive care. Percutaneous transhepatic gallbladder aspiration (PTGBA) is a simple alternative drainage method with fewer complications; however, its clinical usefulness has been shown only by case-series studies. To clarify the clinical value of these drainage methods, proper randomized trials should be done. This article describes techniques of drainage for acute cholecystitis.     

CRISPR,animals, and FDA oversight: Building a path to success

Technological advances, such as genome editing and specifically CRISPR, offer exciting promise for the creation of products that address public health concerns, such as disease transmission and a sustainable food supply and enable production of human therapeutics, such as organs and tissues for xenotransplantation or recombinant human proteins to treat disease. The Food and Drug Administration recognizes the need for such innovative solutions and plays a key role in bringing safe and effective animal biotechnology products to the marketplace. In this article, we (the Food and Drug Administration/Center for Veterinary Medicine) describe the current state of the science, including advances in technology as well as scientific limitations and considerations for how researchers and commercial developers working to create intentional genomic alterations in animals can work within these limitations. We also describe our risk-based approach and how it strikes a balance between our regulatory responsibilities and the need to get innovative products to market efficiently. We continue to seek input from our stakeholders and hope to use this feedback to improve the transparency, predictability, and efficiency of our process. We think that working together, using appropriate science- and risk-based oversight, is the foundation to a successful path forward.     

Relative contributions of cardiorespiratory fitness and visceral fat to metabolic syndrome in patients with diabetes mellitus

The objective of this study was to examine the contribution of endurance fitness and visceral fat accumulation on the prevalence of metabolic syndrome in Japanese male patients with either an impaired glucose tolerance (IGT) or type 2 diabetes mellitus (DM). The subjects of this cross-sectional study consisted of 135 Japanese male patients with either IGT or type 2 DM who had not taken any medication or intervention. They were classified into three fitness categories (low, moderate, and high) based on the tertiles of their maximal oxygen uptake ( [Formula: see text] O(2)max) predicted by the Astrand nomogram using a cycle ergometer. Metabolic syndrome was defined based on the WHO criteria. The visceral fat area (VFA) was determined using a computed tomography scan. The age- and VFA-adjusted odds ratio was 3.49 (95% CI, 1.13-10.82) for subjects in the low fitness category in comparison to those in the high fitness category. We calculated the odds ratio for the prevalence of metabolic syndrome in the nine categories classified based on the three VFA and three [Formula: see text] (2)max levels. In Moderate- and Low- [Formula: see text] (2) max categories, the odds ratios increased in line with increases in the VFA level. The highest odds ratios were observed in the low fitness and high visceral fat group. In the High- [Formula: see text] O(2)max category, no significant odds ratios were observed in the Moderate- and High-VFA categories. These results indicate that a high degree of cardiorespiratory fitness positively contributed to the low prevalence of metabolic syndrome in Japanese male patients with IGT and type 2 DM.     

Differentiation of a human eosinophilic leukemia cell line (EoL-1) by a human T-cell leukemia cell line (HIL-3)-derived factor.

Differentiation of a human eosinophilic leukemia cell line, EoL-1, induced by the culture supernatant of a human ATL cell line, HIL-3 (HIL-3 sup) was compared with differentiation induced by defined cytokines. HIL-3 sup induced EoL-1 cells to express eosinophilic granules and segmented nuclei after 6 to 9 days of incubation. HIL-3 sup also induced the expression of Fc epsilon receptor II (Fc epsilon RII/CD23) and an eosinophil differentiation antigen EO-1 mainly on eosinophilic granule (+) cells. Furthermore, HIL-3 sup induced EoL-1 cells to respond to an eosinophil chemotactic factor, platelet activating factor. HIL-3 cells express messenger RNA (mRNA) of interleukin-5 (IL-5), macrophage colony-stimulating factor (M-CSF), and IL-3 but not granulocyte CSF (G-CSF). Granulocyte-macrophage CSF (GM-CSF) and tumor necrosis factor-alpha (TNF-alpha) were detected in the HIL-3 sup. Recombinant IL-2 (rIL-2), rIL-3, rIL-4, rIL-5, rM-CSF, and rGM-CSF did not induce eosinophilic granules. rG-CSF induced a few eosinophilic granule (+) cells, and TNF-alpha, which did not induce eosinophilic granules by itself, enhanced the ability of G-CSF to induce them. However, G-CSF and TNF-alpha did not induce the expression of Fc epsilon RII and EO-1 antigen. Moreover, anti-G-CSF, anti-TNF-alpha, anti-GM-CSF, anti-IL-3, and anti-IL-5 antibodies did not suppress the effect of HIL-3 sup on the differentiation of EoL-1 cells. All the data suggest that HIL-3 sup contains an unidentified factor that induces differentiation of EoL-1 cells, and that EoL-1 cells and HIL-3 sup provide an important model for the examination of differentiation mechanisms and functions of eosinophils.
