Midwifery scale to support shared decision-making for unplanned pregnancies: A cross-sectional study.

Midwives significantly support women with unplanned pregnancies-promoting a shared perspective on the decision-making process. This study aimed to develop a scale to support midwives to self-assess their practice of this vital role. Following the derivation of scale items and pilot testing, the final version of the scale was administered to 531 midwives to establish internal consistency and construct criterion-related validity. Through exploratory factor analysis, 35 items with a five-factor structure were retained to form the midwifery practice self-assessment scale to promote shared decision-making in women with unplanned pregnancies. These factors illustrate midwives' general aptitude and competencies in understanding environmental factors, collaborating with significant others and the interprofessional group, forming rapport and problem sharing, focusing on consultation content, and promoting autonomous decision-making. There were high and low scores on the scales after attendance of the workshops to support the decision-making of women with unplanned pregnancies. The reliability analysis showed acceptable Cronbach's alpha values for the five factors, from 0.85 to 0.87. The scale was demonstrated to be a reliable and valid measure that would help improve the quality of midwives' practice.

Development of a Neonatal End-of-Life Care Education Program for NICU Nurses in Japan.

We developed the first end-of-life care education program for neonatal intensive care unit (NICU) nurses in Japan. It focused on ethical decision making, care of dying neonates, bereavement, and cultural communication. The program improved nurses' knowledge, F(2.16, 62.5) = 260.6, p < .001, and understanding, F(2.05, 59.4) = 29.1, p < .001, and significantly reduced weaknesses in neonatal end-of-life care. It was considered well designed and may provide further mentoring support for NICU nurses.

Subsequent pregnancy after having a baby who was hospitalized in the NICU.

PURPOSE: To understand experiences of mothers who had a baby hospitalized in the NICU and then decided to have another pregnancy. STUDY DESIGN AND METHODS: We used a descriptive phenomenological approach to study 12 mothers in Japan who had a child hospitalized in the NICU and had a subsequent child. Data were collected by semistructured interviews that occurred two to four times per participant. Data were analyzed using Colaizzi's method. RESULTS: Although all of the mothers had a child who was making steady progress, they experienced difficulty when deciding on having another pregnancy. Our analysis identified five theme clusters: delaying pregnancy; unwavering view about having subsequent children; changing values regarding pregnancy and childbirth; relief of anxiety and fear about repeated hospitalization in the NICU; and preparedness to accept the outcome of pregnancy. CLINICAL IMPLICATIONS: Our study suggests that mothers require support during babies' hospitalization in the NICU and for the process of decision-making about a subsequent pregnancy. Family-centered care as the basis for nursing practice in the NICU is ideal to provide this type of support.

Assessment of East Asian-type cagA-positive Helicobacter pylori using stool specimens from asymptomatic healthy Japanese individuals.

Recent investigations have suggested that CagA, a virulence factor of Helicobacter pylori and known to have multiple genotypes, plays a critical role in the development of stomach cancer. However, the prevalence of cagA-positive H. pylori strains and the cagA genotypes have not been well studied in healthy individuals because of the difficulty in collecting gastric specimens. In the present study, we assessed the prevalence of infection with H. pylori, particularly the strains with the East Asian cagA genotype (which is more potent in causing gastric diseases), among healthy asymptomatic Japanese individuals by a noninvasive method using stool specimens. The H. pylori antigen was detected in 40.3 % of healthy asymptomatic adult individuals (n=186) enrolled in the study. For the detection and genotyping of the cagA gene, DNA was extracted from the stool specimens of these individuals and analysed by PCR. We detected the East Asian cagA genotype in the DNA samples of a significantly high number (63.1 %) of healthy asymptomatic Japanese individuals. These results indicate that a significant number of asymptomatic healthy Japanese individuals were infected with highly virulent H. pylori.

A method for assessment of Helicobacter pylori genotype using stool specimens.

Helicobacter pylori infection has been regarded as a major factor associated with the development of gastric diseases. The characterization of infected H. pylori in asymptomatic individuals is important for the prediction of the onset of such diseases. However, because of the difficulty in obtaining gastric biopsy samples, H. pylori in healthy subjects have not been studied sufficiently. Therefore, we tested a noninvasive method for the characterization of H. pylori using stool specimens. This method involved H. pylori antigen detection in stool specimens by immunochromatography; confirmation of H. pylori DNA by real-time PCR that involved the detection of its 16S rRNA gene in the DNA extracted from stool specimens; and nested PCR with genotype-specific primer pairs. A total of 80 samples obtained from asymptomatic subjects were assessed using this method. The results showed that the prevalence of H. pylori in asymptomatic Japanese individuals was 37.5%. The detection rate of the virulence factor gene cagA was 18.8%. Furthermore, all the detected cagA belonged to the highly virulent East-Asian type. These data suggest that the method used in this study is valuable for studying the molecular epidemiology of H. pylori infection in asymptomatic people.

Helicobacter pylori environmental interactions: effect of acidic conditions on H. pylori-induced gastric mucosal interleukin-8 production.

To explore the interactions between the host, environment and bacterium responsible for the different manifestations of Helicobacter pylori infection, we examined the effect of acidic conditions on H. pylori-induced interleukin (IL)-8 expression. AGS gastric epithelial cells were exposed to acidic pH and infected with H. pylori[wild-type strain, its isogenic cag pathogenicity island (PAI) mutant or its oipA mutant]. Exposure of AGS cells to acidic pH alone did not enhance IL-8 production. However, following exposure to acidic conditions, H. pylori infection resulted in marked enhancement of IL-8 production which was independent of the presence of the cag PAI and OipA, indicating that H. pylori and acidic conditions act synergistically to induce gastric mucosal IL-8 production. In neutral pH environments H. pylori-induced IL-8 induction involved the NF-kappaB pathways, the extracellular signal-regulated kinase (ERK)-->c-Fos/c-Jun-->activating protein (AP-1) pathways, JNK-->c-Jun-->AP-1 pathways and the p38 pathways. At acidic pH H. pylori-induced augmentation of IL-8 production involved markedly upregulated the NF-kappaB pathways and the ERK-->c-Fos-->AP-1 pathways. In contrast, activation of the JNK-->c-Jun-->AP-1 pathways and p38 pathways were pH independent. These results might explain the clinical studies in which patients with duodenal ulcers had higher levels of IL-8 in the antral gastric mucosa than patients with simple H. pylori gastritis.

Helicobacter pylori BabA expression, gastric mucosal injury, and clinical outcome.

BACKGROUND & AIMS: The blood grou. METHODS: We compared the ability of published PCR-based methods to assess BabA status with BabA immunoblotting and Lewis b (Le(b)) binding activity assays. We also used immunoblotting to examine the relationship between clinical presentation and levels of BabA expression. RESULTS: Immunoblotting and Le(b) binding assays for 80 strains revealed 3 levels of BabA expression: BabA high producers (BabA-H) with Le(b) binding activity, BabA low producers (BabA-L) without Le(b) binding activity, and BabA-negative. BabA-negative strains lacked the babA gene. PCR methods to determine BabA status yielded poor results. babA1 sequences were never detected. BabA expression was examined in 250 strains from Western countries and 270 strains from East Asia. The results failed to confirm any relationship between triple-positive status (cagA-positive/vacA s1/BabA-H) and clinical outcome. BabA-negative strains typically were cagA-negative/vacA s2 and were associated with gastritis. BabA-L strains showed a higher level of mucosal injury and were associated more frequently with duodenal ulcer and gastric cancer than the other groups. CONCLUSIONS: Information gained from currently used PCR-based methods must be interpreted with caution. Le(b) binding activity does not accurately reflect the severity of mucosal damage or the clinical outcome. Quantitation of BabA expression revealed that Le(b)-nonbinding BabA-L strains are associated with higher levels of mucosal injury and clinical outcome.
