ABSTRACT

BACKGROUND: The majority of maternity care is provided by female midwives who have either become mothers or are of childbearing age, but there is limited research exploring midwives' own personal childbearing experiences. This integrative review aims to explore the published literature and research on midwives' own experiences of pregnancy and childbirth. METHOD: An integrative review of the literature was conducted after relevant articles were identified through a search of: five electronic databases (Cumulative Index of Nursing and Allied Health Literature (CINAHL), Medline, PubMed, Scopus, and Google Scholar), cited reference lists, and networking with peers. Similar and contrasting patterns and relations within the literature were identified and grouped into themes and subthemes. RESULTS: Twenty articles were included in the review and four overarching themes were identified. Insider knowledge plays a role in decision making encompassed the way midwives used their knowledge to choose; a preferred mode of birth, maternity care provider, model of care, and place of birth. Navigating the childbirth journey demonstrated how some midwives were able to use their insider knowledge to achieve agency, while others had difficulty achieving agency. This theme also revealed the 'midwife brain' that midwives need to manage during their childbearing journey. The theme impact of care on the birth experience described how the type of care the midwives received from maternity care providers affected their overall birth experience. The fourth theme from midwife to mother explains their preparedness for childbirth and their transition to motherhood. CONCLUSION: For childbearing midwives, there is a potential conflict between their position as knowledgeable experts in maternity care, and their experience as mothers. Whilst they can use their insider knowledge to their advantage, they also experience heightened fear and anxiety through their pregnancy. It is important for maternity care providers to acknowledge and support them and provide balanced and tailored care that acknowledges the woman within the professional midwife and the professional midwife within the woman.

ABSTRACT

BACKGROUND: The numbers of children with long-term illnesses surviving into adulthood and transferring from child to adult services has increased dramatically in the last 30 years. This study aimed to examine health-related quality of life pre- and post-transfer from child to adult healthcare for young people with three long-term illnesses. METHODS: A total of 217 young people with cystic fibrosis, congenital heart defects or diabetes attending child and adult hospital services in Dublin, Ireland completed a questionnaire survey. Multiple linear regression was used to identify predictors of five dimensions of health-related quality of life pre- and post-transfer. RESULTS: Post-transfer young people with congenital heart disease and diabetes reported significantly lower physical well-being than their pre-transfer counterparts. Pre-transfer young people with cystic fibrosis reported significantly lower physical well-being than those with diabetes, but there was no significant difference post-transfer. Pre-transfer females reported lower scores than males on the Psychological Well-being and Autonomy and Parent Relation dimensions; however, these differences disappeared post-transfer. Higher maternal overprotection scores were associated with significantly lower scores on the Psychological Well-being, Autonomy and Parent Relation, and Social Support and Peers dimensions, regardless of transfer status. CONCLUSIONS: Disease group, gender and maternal overprotection were predictors of health-related quality of life pre- and post-transfer from child to adult healthcare. Transition programmes should promote self-management and discourage parental overprotection.

ABSTRACT

BACKGROUND: 22q11.2 deletion syndrome (22q11DS) is a multisystem genetic condition with a broad phenotype. It is associated with a high prevalence of depression and anxiety during childhood and increased risk of schizophrenia in adulthood. Despite this, studies report that families may receive inadequate information of mental health (MH) risks at diagnosis. Therefore, this study investigated parents' experiences of caring for a child with 22q11DS, investigated their knowledge regarding the risk of MH problems and assessed the need for a psycho-educational programme. METHODS: A qualitative design and purposeful sampling was utilized. Parents registered with the '22q11 Ireland' support group, and parents listed on the cleft palate database in a children's hospital in Ireland were invited to participate. Focus groups were held with 22 parents. Data were thematically analysed using Burnard's method of analysis. RESULTS: Most parents had some knowledge of the relationship between 22q11DS and an increased risk of MH issues. Parents reported that MH information relating to 22q11DS was mainly obtained from 22q11DS conferences, the '22q11 Ireland' support group and the Internet. Parents expressed a need for information to prevent or cope with their child's MH issues. Parents suggested that the following topics would be quite useful in a psycho-educational programme. These included information on the early warning signs of MH issues and guidance on when and how to tell the child about the condition and how to manage the child or young person's anxiety, obsessive behaviour or hearing voices. CONCLUSIONS: The findings indicated parental support for a psycho-educational programme that would provide relevant, accurate and timely information on how to effectively care for a child with 22q11DS MH needs.

ABSTRACT

INTRODUCTION: Despite the transition between child and adult services for young people with Type 1 diabetes mellitus being a high-risk period, little is known about the impact of healthcare transition upon young people. METHODS: A systematic review was conducted using PubMed, PsycINFO, CINAHL and EMBASE. Papers published between January 2001 and June 2014 that examined the impact or experiences of healthcare transition in young people with Type 1 diabetes were included. Data were extracted by two independent reviewers and integrated by narrative synthesis. RESULTS: A total of 8990 citations were reviewed and 43 studies were included in the review, 24 of which explored the impact of transition and 24 examined experiences of transition. There were mixed results in terms of the change in glycaemic control and diabetes-related hospitalizations, but all studies assessing attendance found worse attendance post-transition. Data regarding experiences reported that young people and parents experienced greater difficulty in accessing and maintaining diabetes health care. Young people were required to develop independent self-management and self-advocacy skills to navigate the transition and adult health care, but some were inadequately prepared for this. CONCLUSIONS: Although the impact of healthcare transition on outcomes for young people with Type 1 diabetes is unclear due to the paucity of high-quality studies, transition appears to be associated with decreased clinic attendance. There is some preliminary evidence of a positive impact of structured transition programmes. Experiences of healthcare transition illuminate the barriers to smooth transitions and the need for better integration and continuity of care.

ABSTRACT

BACKGROUND: Maternity care in Australia is predominantly provided by midwives, many who give birth. There is a paucity of research on midwives' own childbearing preferences and experiences. AIM: To explore midwives childbirth preferences and outcomes when giving birth to their first child in Australia, after qualifying as a midwife. METHODS: An online national survey. Data were analysed using descriptive statistics. FINDINGS: 447 midwives responded, with the majority of midwives indicating a preference for a normal vaginal birth with a known care provider under a continuity of midwifery care model. For midwives who were first time mothers, 66% had normal vaginal births, 16.3% had an instrumental birth, and 16.8% had caesarean births. Over 85% of midwives received the model of care they wanted and 45% had continuity of midwifery care. While a quarter of midwives wanted a homebirth,11.2% achieved this. Over three quarters (75.4%) of midwives were cared for by a care provider of their choosing. DISCUSSION: There was a difference in models of care accessed and birth outcomes between midwives and other women giving birth for the first-time in Australia. Australian midwives appear to have the advantage of clinical and scientific knowledge to navigate the maternity care system to get the birth care and outcomes they want. CONCLUSION: It is possible that professional experience, insider knowledge, and existing relationships with other midwifery friends and colleagues, affords midwives a higher degree of agency and autonomy when it comes to getting the maternity care and birth outcomes that they want.

ABSTRACT

BACKGROUND: Multiple-mini interviews (MMI) are increasingly used as part of the admission process into healthcare degrees. Evaluations have found MMIs to be a fair assessment tool in terms of reliability and validity and viewed positively by those involved in the MMI process. The use of MMIs in midwifery is novel and evaluation is lacking. AIM: To evaluate the use of MMIs as part of the admission process for the Bachelor of Midwifery in one Australian university. METHODS: A basic convergent mixed methods study design was utilised. Data included linked data sets, Likert scale responses to survey questions, focus groups and open-ended survey questions. Integration took place at the interpretation and reporting stage. FINDINGS: Participants viewed the MMI experience positively. The study confirmed the reliability of the MMIs as an assessment tool. Most variance in MMI scores was attributed to the candidate at 31.4 % with the interviewer and the interview station having less influence on the MMI score at 11 % and 6.4 % variance. Older applicants on average achieved higher MMI scores, and those who spoke a language other than English at home or were first in family to attend university had lower on average MMI scores. Being born overseas did not impact an applicant's MMI score. The overall experience was seen as fair, offering further opportunity to gain entry into the Bachelor of Midwifery. CONCLUSION: MMIs were viewed positively and findings support the use of MMIs as part of an admissions process for the Bachelor of Midwifery.

ABSTRACT

AIM: To describe the implementation and evaluation of a midwife/midwifery student-mentoring program in one Local Health District in Sydney NSW Australia. BACKGROUND: Evidence suggests well designed and supported midwife/midwifery student mentorship programs can make a difference to the clinical placement experiences and attrition rates of midwifery students. DESIGN: In the evaluation of the mentoring program, we used surveys, focus groups and individual interviews. METHODS: Eighty-six participants, including midwife mentors, midwifery students, non-mentor midwives and midwifery managers participated in the evaluation. Quantitative data were analysed using descriptive statistics and qualitative data, content analysis. RESULTS: The mentoring program increased midwives' mentoring skills and was beneficial to their professional growth and leadership skills. Students reported positive outcomes including someone to talk to, emotional support and a sense of belonging. Mentoring programs require structure, mentor training, organisational support and transparency. CONCLUSION: The mentoring program provided benefits to both midwifery mentors and students and demonstrated the value of a structured and supported mentoring program for midwifery students.

ABSTRACT

BACKGROUND: Admission to the Bachelor of Midwifery (BMid) in Australia has traditionally been based on academic ranking. The BMid is a high demand course offered to a limited number of students and therefore choosing applicants who complete the degree is important. Multiple Mini Interviews (MMIs) are used to assess non-cognitive skills and select students into healthcare degrees. One university in Australia has introduced MMIs as part of the application process for the BMid. AIM: Compare attrition rates and Grade Point Average (GPA) scores between students admitted into the BMid using both academic ranking and MMIs, to those admitted on academic ranking alone. METHODS: A basic convergent mixed methods design, using an explanatory unidirectional framework to integrate data. Attrition rates, GPA, and multiple mini interview scores (2013-2019), were linked and compared for before and after the use of MMI's. Focus groups with students, interviewers, and hospital-based educators, explored stakeholder experiences. Open-ended questions from an applicant survey were added to the qualitative data set, which was analysed thematically. FINDINGS: Students who enrolled via the MMI's had significantly lower attrition rates than those enrolled before MMI's were introduced. GPA scores were significantly higher for students who enrolled via the MMI's. Integration of data found MMI's identified students passionate to undertake midwifery, and that success at the interviews increased students' confidence to successfully complete their studies. CONCLUSION: MMI's as part of the entry process into the BMid enabled identification of applicants more likely to remain in the course and succeed in their studies.

ABSTRACT

BACKGROUND: Good mentoring is important for students to support their adjustment to and learning in the clinical environment. The quality of the mentoring relationship is key for students but there is a lack of evidence explaining how a good mentor/mentee relationship establishes and develops over time. AIM: To explore the developing relationship between mentors and mentees participating in a structured midwifery mentoring program in one Local Health District in Sydney, Australia. METHODS: A qualitative interpretive descriptive research design was utilised. Data were collected using 10 focus groups with midwife mentors (n = 31) and seven focus groups and four interviews with Bachelor of Midwifery student mentees (n = 24), over a 12-month period. Thematic analysis using an inductive approach was applied incorporating constant comparison to identify themes and sub-themes. FINDINGS: Three overarching themes and three sub-themes were identified. The first theme was 'The great unknown'. Within the second theme 'Building the relationship' were three subthemes: trying to connect; becoming known; and an insider on your side. The final theme 'the virtuous circle' described the reciprocal relationship and benefits that developed between mentor and mentee. DISCUSSION: The mentor/mentee relationship took time to develop and went through a number of phases. A positive mentor/ mentee relationship flattened hierarchical differences, increased student confidence and capacity for learning, and reflected the midwifery continuity of care relationship between midwife and woman built on respect and partnership. CONCLUSION: Developing a successful midwifery mentoring relationship takes persistence, reassurance, and mutual disclosure ultimately resulting in a recurring cycle of encouragement and support.

ABSTRACT

OBJECTIVE: Co-design information and website to support adolescents and young adults with long-term illnesses in their transition to adult healthcare. METHODS: A participatory iterative process involving a survey (n=207), twenty-one interviews, six participatory workshops, six video recordings, two advisory groups, and a co-design group to identify needs and preferences for e-health and information provision, was used to develop an appropriate intervention. RESULTS: Adolescents and young people expressed preferences for information that was trustworthy, empowering, colorful, easily downloaded online and written using non-patronizing language. They desired video testimonials of experiences from young adults who had transitioned to adult healthcare and wanted advice about becoming more independent, managing their condition, preparing for the transition, and information about medications and the differences between child and adult healthcare. They also wanted information about the location and configuration of adult healthcare, key hospital personnel, and frequently asked questions. CONCLUSION: The participatory iterative process led to the development of an online resource specifically tailored to the adolescents and young people's transition needs and information preferences. Preliminary feedback indicates that it is a valued resource. PRACTICE IMPLICATIONS: The www.SteppingUP.ie website has the potential to help prepare its target population group for the transition to adult healthcare.

ABSTRACT

The serum free T4 index (FT4I) was at or below the lower limit of normal in 8 of 55 unselected patients with hyperprolactinemia. Serum levels of T3 were normal and none of the patients had clinical evidence of hypothyroidism. In patients with low FT4I the serum TSH was within the normal range and TSH was released normally after administration of TRH, indicating normal pituitary TSH reserve. Serum TSH also increased after administration of the dopamine antagonist domperidone. The TSH response to domperidone was significantly greater in the hyperprolactinemic group with low FT4I compared with either normal subjects or hyperprolactinemic patients with normal FT4I, suggesting that depression of FT4I was due to increased dopaminergic activity. Administration of the dopamine antagonist metoclopramide for 4 days led to a supranormal rise in FT4I in 3 of 5 patients with low FT4I. Thus, a minority of hyperprolactinemic patients have a low FT4I which appears due to excessive hypothalamic production of dopamine.

ABSTRACT

Peutz-Jeghers syndrome is characterized by multiple polyps throughout the gastrointestinal tract in association with mucocutaneous pigmentation. Small bowel polyps in the syndrome may exhibit epithelial misplacement, into the submucosa, the muscularis propria, and even the subserosa. The authors demonstrate two patients in whom there is also misplacement of dysplastic epithelium into the submucosa and muscularis propria of the small bowel. Epithelial misplacement is recognized to mimic invasive malignancy. Such mimicry is heightened substantially when the misplaced epithelium is dysplastic. Correct interpretation of the histologic changes is aided by the use of special stains, which demonstrate the associated lamina propria and the lack of a desmoplastic response, and immunohistochemistry, which shows that the misplaced dysplastic epithelium is accompanied by non-neoplastic mucosa. There is an increased prevalence of gastrointestinal malignancy in Peutz-Jeghers syndrome. However, the presence of perplexing histologic features, caused by epithelial misplacement, especially when some of that epithelium is dysplastic, in small bowel polyps at least has the potential for the overdiagnosis of malignancy in the syndrome.

ABSTRACT

We examined the effect of intravenous (i.v.) tolbutamide administration on glucose and hormone levels in cystic fibrosis (CF) patients with impaired first-phase insulin secretion and oral glucose tolerance (oral glucose tolerance test [OGTT]) and compared them with CF patients with only an impaired first-phase insulin secretion and healthy control subjects. Five CF patients with an impaired OGTT, ie, a serum glucose value of 7.8 mmol/L or greater 120 minutes after an oral glucose load (group I), five CF patients with a normal OGTT, ie, a serum glucose not exceeding 7.8 mmol/L 120 minutes after oral glucose (group II), and five healthy control (CON) subjects underwent IV glucose tolerance tests with glucose alone (IVGTT) and glucose administered in conjunction with tolbutamide ([IVTTT] 25 mg/kg; maximum dose, 1 g). Serum glucose levels were measured using the glucose oxidase method; insulin, C-peptide, and glucagon levels were measured by the double-antibody radioimmunoassay (RIA) technique. Serum immunoreactive trypsin (IRT) and hemoglobin A1 (HbA1) levels and height and weight were measured for each subject, and in addition, pulmonary function was assessed in those with CF. There were no significant differences in the area under the curve (AUC) for glucose or glucose or glucagon levels or the serum glucose disappearance rate (k value) between group I, group II, or CON subjects during the IVGTT. First-phase insulin and C-peptide secretion was abnormal during IVGTT and IVTTT in the CF groups: in group I it was severely impaired, whereas in group II it was between group I and CON values. During the IVTTT serum glucose levels and glucose k values were not significantly altered in any of the three groups as compared with the IVGTT.(ABSTRACT TRUNCATED AT 250 WORDS)

ABSTRACT

A prospective, randomized, controlled study was performed in neonates in an intensive care nursery to compare the performance of a peripheral intravenous catheter made of Aquavene material (test catheter) with that of a conventional peripheral catheter made of Teflon material (control catheter). Aquavene is a newly developed biomaterial that softens and expands on contact with body fluids. A total of 105 catheters (50 test and 55 control) were inserted in 63 neonates. The median time to a catheter-related complication was 3.60 days for the test catheters and 1.75 days for the control catheters (p = 0.0007). Infiltration rate for the test catheters was 56% as compared with 78% for the control catheters (p = 0.03). The test catheters provided fewer catheter-related complications (p = 0.006), with 34% of the test catheters reaching end of therapy as compared with 9% of the control catheters (p = 0.004). On average, 1.8 test catheters were used per insertion versus 2.3 control catheters (p = 0.08). The test catheters were rated easier to insert (p = 0.05), with a shorter time required for insertion. Because of improved performance, cost savings were realized with the test catheters after the first day of therapy, even though the per unit cost of the test catheter was greater. These data indicate that the test catheter, made of Aquavene material, is superior to the Teflon catheter for peripheral intravenous therapy in neonates.

ABSTRACT

The efficiency of removal of lead (Pb) and other elements from natural drinking waters using a bench-top water filter system was evaluated in three recently-built houses in Sydney, Australia, and two from rural centres. In addition, one filter system was tested for copper (Cu), Pb and cadmium (Cd) under rigorously-controlled laboratory conditions using Sydney water. For two Sydney houses, the efficiency was evaluated using special filter cartridges concomitant with the ordinary filters. Waters after passing through the filter, was sampled when the filter had been exposed to '0', 50, 100, 150, 200, and 250 l respectively and were analysed for lead isotopes and lead concentrations by high precision isotope dilution mass spectrometry. Samples that passed through the filter after '0', 50, 150 and 250 l collections were analysed for four anions and 39 cations by various methods. Sydney water was fairly uniform in its anion and cation composition, whereas water from the two rural areas contained higher concentrations of Ca, Mg and HCO3. Effects of the filter on the water compositions can be summarised into three groups: (1) elements removed during filtration--Ca, Mg, Sr, Ba, Cu, Pb, Zn and Ni. With 'age' of the filter, the efficiency of removal for Pb was maintained in the two houses with Pb concentrations greater than 10 micrograms/l in the first flush water and was maintained for Cu through all concentrations. Ca, Mg, Sr and Ba were largely removed in the first 50 1 of usage. (2) Elements added during filtration--K, Rb, Ag and P. Except for Ag, which was present throughout the testing period, these elements were added only in the first filtration. (3) Elements unaffected by filtration--Al, Si, Na, Fe, Cl and F. Efficiency of Pb removal from tap water by this system depends generally on the initial Pb content in the water. However, it also seems to depend, to some extent, on Pb speciation and water composition, as found in earlier studies of natural waters. The control in filtering efficiency as a function of Pb speciation and chemical composition becomes more important at low initial Pb concentrations in the water. However, the Pb concentrations at which speciation and water composition appear to play a role in filter efficiency are so low that these factors, though scientifically interesting, have no relevance from a practical point of view, especially the impact on human health. Acidification of six sets of duplicate water samples, one sample immediately after collection and the other acidified after more than 2 weeks, showed negligible changes in Pb or Cu concentrations between duplicates.

ABSTRACT

The variation in lead concentration was measured by thermal ionisation mass spectrometry isotope dilution in household tap water throughout the day when the plumbing system was not fully flushed. After collection of an initial 125-ml water sample containing 119 micrograms/l and a 2-l sample, 125-ml samples were collected at hourly intervals for 8 h. The concentrations in the hourly samples remained in the range 35-52 micrograms/l compared with 1.7 micrograms/l for fully flushed water. High precision lead isotopic measurements showed that approximately 50% of the lead in these water samples derives from the tap 'housing' compared with the overall household system. A health risk assessment was performed employing the US Environmental Protection Agency Integrated Exposure Uptake Biokinetic Model. Predicted blood lead levels in infants only exceeded the 'levels of concern' of 10 micrograms/dl when 100% of the water consumed contained 100 micrograms Pb/1. It would appear that unless the infant consumed 100% of first flush water at lead concentrations of approximately 100 micrograms/l, the blood lead would not exceed the recommended 'level of concern'. However, if more than 0.51 was consumed in drinks and formulae using first flush water, then the blood lead could easily exceed the recommended level. Likewise, a pregnant mother could be at risk of consuming considerably more than the 0.51/day first flush water of the concentrations measured, or throughout the day, if the system were not fully flushed.

ABSTRACT

The mortality rate for infants severely affected with congenital diaphragmatic hernia (CDH) remains high despite significant advances in surgical and neonatal intensive care including delayed repair and extracorporeal membrane oxygenation (ECMO). Because of the increasingly successful experience with single-lung transplantation in adults; this approach has been suggested as a potential treatment for CDH infants with unsalvageable pulmonary hypoplasia. The authors report on a newborn female infant who was the product of a pregnancy complicated by polyhydramnios. At birth, she was found to have a right-sided CDH and initially was treated with preoperative ECMO, followed by delayed surgical repair. Despite the CDH repair and apparent resolution of pulmonary hypertension, the infant's condition deteriorated gradually after decannulation, and escalating ventilator settings were required as well as neuromuscular paralysis and pressor support because of progressive hypoxemia and hypercarbia. A lung transplant was performed 8 days after decannulation, using the right lung obtained from a 6-week-old donor. The right middle lobe was excised because of the size discrepancy between the donor and recipient. After transplantation, the patient was found to have duodenal stenosis and gastroesophageal reflux, which required duodenoduodenostomy and fundoplication. The patient was discharged from the hospital 90 days posttransplantation, at 3 1/2 months of age. Currently she is 24 months old and doing well except for poor growth. This case shows the feasibility of single-lung transplantation for infants with CDH, and the potential use of ECMO as a temporary bridge to transplantation. Lobar lung transplantation allowed for less stringent size constraints for the donor lung.

ABSTRACT

Solitary fibrous tumours are uncommon neoplasms that have been described as occurring in the pleura, peritoneum, lung, mediastinum, pericardium, nose and paranasal sinuses. This report describes the first known case of a solitary fibrous tumour of the diaphragm, occurring in a 60 year old woman with a two year history of respiratory symptoms. The lesion was initially misdiagnosed as an elevated left hemidiaphragm. The operative findings and histological appearance of the tumour are described. A review of the literature examines the various types and presenting features of solitary fibrous tumours as well as their clinical behaviour and postulated origin.

ABSTRACT

This article discusses the development of an innovative role for oncology nurses in assisting patients with their personal information and image needs that arise from alopecia secondary to the treatment of cancer. An independent oncology nursing consultative service was initiated after a survey of patients was conducted (N = 40) to assess alopecia knowledge, needs, and referral source. Nurses (N = 16) attending a local Oncology Nursing Society (ONS) chapter meeting were surveyed to assess their intervention patterns and knowledge of hair and scalp care during hair loss. To respond to needs identified through the surveys, the consultative service developed a patient education program and booklet, as well as professional education sessions. Management and evaluation of this practice continues to provide a learning experience.

ABSTRACT

A case of pancreatitis that occurred as a complication of a vaso-occlusive crisis in a child with sickle cell anemia is reported. We encourage others to consider pancreatitis as a cause for abdominal pain in children with multisystem diseases, particularly those that may cause ischemic organ injury such as sickle cell anemia.
