ABSTRACT

Background: In 2016, the World Health Organization recommended salt reduction strategies. In most low- and middle-income countries, little is known about what causes people to reduce their salt intake. Aim: In rural West Java, Indonesia, we conducted a cross-sectional survey to describe self-reported salt reduction practices among middle-aged Muslims with hypertension (n = 447) and to identify correlates of salt reduction. Methods: We developed a questionnaire with Likert scales to measure self-reported frequency of efforts to reduce salt intake, and degree of agreement/disagreement with 51 statements about variables hypothesized to influence salt reduction practices. We compared groups using t-tests and one-way ANOVAs. Through one-factor confirmatory factor analysis and structural equation modeling, we identified correlates of salt reduction practices. Results: About 45% of participants reported regularly reducing their salt intake; only 12.8% reported never attempting. Men reported higher social barriers, while women reported higher family support and spiritual support. Overall, we found that participants' frequency of effort to reduce their salt intake was associated with a constellation of six correlates. Salt reduction practices were directly positively associated with prior health/illness experiences (ß = 0.25), and by seeking health information (ß = 0.24). Seeking health information was in turn positively associated with prior health/illness experiences (ß = 0.34), receiving support from health professionals (ß = 0.23) and Islamic spiritual practice (ß = 0.24). Salt reduction practices were negatively associated with environmental barriers to healthful eating practices (ß = -0.14). Conclusion: In this population, reinforcing positive correlates identified in this study and mitigating against negative correlates may foster salt reduction practices.

ABSTRACT

OBJECTIVES: This study aimed to qualitatively analyze the experiences and perceptions of students at a nursing college in Japan who studied abroad in Asia and North America, thereby identifying the full range of benefits of study abroad programs for Japanese nursing students. METHODS: We conducted a qualitative analysis of the reflection papers and free-response questionnaire items completed by 50 Japanese undergraduate nursing students who participated in 9 study abroad programs in Asia and North America. Content analysis of the data proceeded from typological and deductive to data-driven and inductive, recursively and collaboratively. RESULTS: The results reveal perceived benefits in the areas of English language proficiency and motivation; knowledge of nursing practices, healthcare systems, and global health; cultural awareness and sensitivity; and various types of identity development (second-language motivation and identity, national/ethnic identity, professional identity, identity as a global citizen, and personal growth). It was also shown that students' perceptions of what they learned or gained varied according to the specific characteristics of each study abroad program. CONCLUSIONS: Study abroad experiences are often critical turning points that enhance nursing students' identity formation in the context of multiple and overlapping communities of practice. They also enhance core elements of the educational mission of a nursing college, particularly relating to liberal arts and internationalization. These findings can inform the development of assessment tools to be used in conjunction with study abroad programs at nursing colleges.

ABSTRACT

Hypertension is a significant health issue in Indonesia. Health professionals in a rural district of West Java identified hypertension as a priority health issue. In this study, we describe healthy-lifestyle behaviors as perceived by the district's middle-aged Muslims with hypertension. A qualitative case-study design was used. Twelve married couples, directly or indirectly impacted by hypertension, and who visited community health centers, were purposively recruited. Semistructured interviews provided data that were systematically analyzed for categories and subcategories. Categories of healthy-lifestyle behaviors currently practiced were eating behavior, physical activity, resting, not smoking, managing stress, seeking health information, seeking health care, caring other people, and fulfilling an obligation to God. Categories of reasons for practicing healthy-lifestyle behaviors were behavioral beliefs, competence, religious support, prior experience, social support, and health system support. Categories for not practicing healthy-lifestyle behaviors were personal, social, and environmental barriers. To achieve healthy-lifestyle behavior changes, it is essential for rural middle-aged Muslim individuals to be supported by reinforcing their positive reasons and to address their negative reasons to practice healthy-lifestyle behaviors.

ABSTRACT

BACKGROUND: In the United Republic of Tanzania, the maternal mortality ratio, and neonatal mortality rate have remained high for the last 10 years. It is well documented that many complications of pregnancy are avoidable by providing skilled midwifery care during and immediately after childbirth. However, there have been delays in providing timely and necessary obstetric interventions, most likely due to lack of proper monitoring during labor. Yet, there has been little research concerning how midwives monitor the process of childbirth. Therefore, this study aimed to describe how midwives monitored and managed the process of childbirth to achieve early consulting and timely referral to obstetricians. METHODS: The design was qualitative and descriptive, using data from comprehensive semi-structured interviews of midwives. The interviews were conducted at one hospital and one health center in Dar es Salaam, Tanzania's largest city. Eleven participants were purposively recruited and interviewed about their experiences managing complicated intrapartum cases. After the interviews, data were analyzed using content analysis. RESULTS: Derived from the data were three activity phases: initial encounter, monitoring, and acting. During these phases, midwives noticed danger signs, identified problems, revised and confirmed initial problem identification, and organized for medical intervention or referral. The timing of taking action was different for each midwife and depended on the nature of the prolonged and obstructed labor case. CONCLUSIONS: For the majority of midwives, the processing of assessments and judgments was brief and without reflection, and only a few midwives took time to continue to monitor the labor after the initial identification of problems and before taking actions. To make a final judgment that the labor was becoming prolonged or obstructed, midwives should consider taking time to review and synthesize all their findings.

ABSTRACT

AIM: The aim of this concept analysis was to describe attributes, antecedents, and consequences of reflection in nursing professional development, as well as surrogate terms and a model case to inform nursing educators, students, and nurses about developing reflective skills. METHODS: Rodgers' evolutionary cycle for concept analysis was used. The published work search was conducted using five databases: Education Resources Information Center (ERIC), Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Ichushi, and British Nursing Index. The inclusion criteria were: (i) academic articles; (ii) written in English or Japanese; and (iii) including descriptions about reflection. From the pool of extant published work, 50 articles were selected for the thematic analysis. RESULTS: For the concept of reflection in nursing professional development, four antecedents were identified: (i) theory and practice gap; (ii) expansion of the role and competency in nursing; (iii) educational and learning needs; and (iv) educational responsibility. The major attribute was the process of learning from experience, and the circular process included emotional reaction, description, internal examination, critical analysis, evaluation, and planning new action. The consequences were transforming new perspective, enhanced communication, professional development, and quality of care. CONCLUSION: Reflection is used as a method or tool that connects knowledge and experiences. Through the process of reflection, students/nurses become aware of themselves, which helps them review and improve clinical skills. They also become more able to communicate with patients and colleagues. Reflection enhances self-directed learning and professional maturity. Nurses who use reflection can be better positioned to provide excellent patient care.

ABSTRACT

Declining availability and accessibility of perinatal health care are emergent social concerns. Based on the Listening to Mothers-II (LTM-II) surveys, we describe a total of 20 Japanese women's perinatal experiences. Data were qualitatively compared with those of U.S. women, using a theoretical framework for evaluation of primary health care. Japanese women overcame their worries by engaging in healthy behaviors, accepting hardships such as labor pain, and receiving assurance from health professionals and modern technology. We found that while U.S. and Japanese women's perinatal experiences reflected their unique cultural values and social context, a cross-cultural universality of birthing women's experiences exists.

ABSTRACT

The questionnaire used for the U.S. Listening to Mothers II survey was translated and culturally adapted to measure Japanese women's experience during the period of pregnancy planning through early postpartum. Methods included expert panels and two phases of cognitive interviews with 20 postpartum Japanese adult women. The number of problems with the translated questionnaire effectively decreased in the iterative process. Most problems were found in the question-interpretation stage of cognitive processing, such as wording/tone. Culture-specific concepts and unclear items were adapted to prevent erroneous interpretations in future studies. The future use of this questionnaire to generate data sets will be useful for professionals interested in developing evidence-based practices. The knowledge from this study can be helpful in improving health-care services and education for women with diverse languages and cultural backgrounds.

ABSTRACT

INTRODUCTION: After the World Health Assembly approved the WHA 45.5 in 1992, which addressed the nursing shortage by refocusing nurses and midwives to meet community health needs, community demands for educated nurses and the needs of higher nursing education in developing countries increased. However, in developing countries that suffering from multiple resource deficiencies, such as Kenya, the strategic direction of higher education in nursing was unclear. Therefore, in Kenya, a major university school of nursing initiated a collaborative study with a well-established Japanese nursing college to determine the service-providers' perspective about upgrading the Master's community nursing curriculum. PURPOSE: The aim of the study was to describe the Kenyan stakeholders' perspective and the expected roles and abilities of Master's graduates in community nursing. METHODS: This qualitative, cross-sectional study used convenience sampling to obtain 21 participants. The content analysis of the data was based on 19 semistructured interviews. RESULTS: Sixteen categories and 42 subcategories were derived from the five key questions that related to the expectations of the Master's program. The Master's graduates were expected to acquire knowledge and skills relating to administration, management, epidemiology, research, and education. The participants recognized that epidemiology, important for preventive care, was minimal among the current community health nurses. Also, Master's graduates must be prepared to manage health programs. CONCLUSION: The stakeholders expected that Master's graduates would become leaders in community health nursing, with a broad range of knowledge and skills, most notably in the areas of management and administration, epidemiology, and research. Those abilities should be reflected in the curriculum content.

ABSTRACT

CD8(+) cytotoxic T lymphocytes (CTLs) generated by immunization with allogeneic cells or viral infection are able to lyse allogeneic or virally infected in vitro cells (e.g., lymphoma and mastocytoma). In contrast, it is reported that CD8(+) T cells are not essential for allograft rejection (e.g., heart and skin), and that clearance of influenza or the Sendai virus from virus-infected respiratory epithelium is normal or only slightly delayed after a primary viral challenge of CD8-knockout mice. To address this controversy, we generated H-2(d)-specific CD8(+) CTLs by a mixed lymphocyte culture and examined the susceptibility of a panel of H-2(d) cells to CTL lysis. KLN205 squamous cell carcinoma, Meth A fibrosarcoma, and BALB/c skin components were found to be resistant to CTL-mediated lysis. This resistance did not appear to be related to a reduced expression of MHC class I molecules, and all these cells could block the recognition of H-2(d) targets by CTLs in cold target inhibition assays. We extended our observation by persistently infecting the same panel of cell lines with defective-interfering Sendai virus particles. The Meth A and KLN205 lines infected with a variant Sendai virus were resistant to lysis by Sendai virus-specific CTLs. The Sendai virus-infected Meth A and KLN205 lines were able to block the lysis of Sendai virus-infected targets by CTLs in cold target inhibition assays. Taken together, these results suggest that not all in vivo tissues may be sensitive to CTL lysis.

ABSTRACT

We previously demonstrated that around 6 weeks of age most of the interferon-gamma (IFN-gamma)(-/-) but none of the IFN-gamma(+/+) C57BL/6 mice began to lose hair in their dorsal or occipital areas or both and that a single s.c. injection of IFN-gamma into IFN-gamma(-/-) mice at 3 but not at 8 weeks of age (or later) could protect all the mice from alopecia. Here, we report hair regrowth in the alopecia site of IFN-gamma(-/-) mice at 8 weeks of age (or later) by the combination of IFN-gamma and allografting. Skin or tumor allografting and IFN-gamma injections into the transplantation site induced hair regrowth in the alopecia site of IFN-gamma(-/-) mice at 8-66 weeks of age, whereas IFN-gamma injections into the hairless site or allografting alone was ineffective in causing the hair regrowth. Histologic findings showed that the hair cycle in the region of alopecia of IFN-gamma(-/-) mice was blocked at the anagen stage and that in the IFN-gamma(-/-) mice treated with IFN-gamma and allografting, the cycle was at the telogen stage. The therapeutic effects were maintained for >1 year.

ABSTRACT

Activation-induced cytidine deaminase (AID) is the essential and sole B cell-specific factor required for class-switch recombination (CSR) and somatic hypermutation (SHM). However, it is not known how AID differentially regulates these two independent events. Involvement of several cofactors interacting with AID has been indicated by scattered distribution of loss-of-function point mutations and evolutionary conservation of the entire 198-amino-acid protein. Here, we report that human AID mutant proteins with insertions, replacements or truncations in the C-terminal region retained strong SHM activity but almost completely lost CSR activity. These results indicate that AID requires interaction with a cofactor(s) specific to CSR.

ABSTRACT

Hair growth abnormalities in mice usually are accompanied by histologic abnormalities as well. Recently, however, we reported a mouse model in which an arrest of the hair cycle and diffuse shedding of the hair without pathologic features induced alopecia in interferon-gamma(-/-) (IFN-gamma(-/-)) C57BL/6 (B6) mice. Here, we explored the cellular origin of IFN-gamma. When bone marrow from IFN-gamma(-/-) B6 mice was transplanted into lethally irradiated IFN-gamma(+/+) B6 mice, the level of IFN-gamma mRNA expression in the skin or peripheral blood mononuclear cells (PBMCs) of recipient mouse was markedly reduced, suggesting that IFN-gamma is normally produced by bone marrow-derived cells. Although severe combined immunodeficiency (SCID) mice lack mature T cells and B cells, IFN-gamma-dependent hair regrowth was induced in SCID mice by depilation, which caused alopecia in IFN-gamma(-/-) B6 mice. Consistently, IFN-gamma mRNA expression in the skin or PBMC from SCID mice was comparable to that from their genetic counterpart (BALB/c mice), suggesting IFN-gamma production by non-T cells. RT-PCR analyses after separation of PBMC from SCID mice into eight fractions by a cell sorter revealed that Mac-1(+) cells were the major origin of IFN-gamma.

ABSTRACT

Using Ca2+ -selective microelectrodes based on the neutral carrier, ETH-1001 with polyvinyl chloride (PVC), we have measured changes in the free Ca2+ concentration of guinea pig cochlear endolymph ([Ca](e)) after transient asphyxia or intravenous administration of diuretics. Under the control conditions, the endocochlear potential (EP) was +80 mV, and the [Ca](e) was in the range 1.4 x 10(-7)-2.4 x 10(-6) M (n = 16). Transient asphyxia (1-1.5 min) produced an increase in the [Ca](e) with a fall in the EP, whereas the cessation of the asphyxia led to a quick recovery of both [Ca](e) and EP to their control levels. Intravenous administration of furosemide (60 mg/kg) or bumetanide (30 mg/kg) also caused an increase in the [Ca](e) with a fall in the EP, followed by a gradual recovery of both [Ca](e) and EP. From these results, we obtained a significant correlation between EP and p[Ca](e) (= -log[Ca](e)), and conclude that (1) the [Ca](e) is extremely low, around 10(-6) M or less, under normal conditions and (2) the [Ca](e) is directly correlated with EP under physiological conditions.

ABSTRACT

The purpose of this study was to explore health promoting lifestyle behaviors (HPLBs) of college women in Japan. In addition, perceived health status and concerns were evaluated. The methods used were both qualitative and quantitative. The qualitative data from focus groups with 38 Japanese college women were used to develop a questionnaire. Subsequently, 546 randomly selected college women responded to the mailed survey (response rate 54%). Forty percent of the college women respondents perceived themselves as "rather unhealthy" or "unhealthy." The investigator conclude that (1) perceived HPLBs, health status, and health concerns were mutually associated, thus, to increase perceived health status and/or decrease perceived health concerns, promoting healthy lifestyle behaviors must be considered; (2) the number of perceived motives or cues and the number of perceived health concerns of importance to college women must be considered to promote healthy lifestyle behaviors.
