Potential challenges of using narrative inquiry with at-risk young people
Aim: To present an overview of several challenges that arose when conducting narrative research with at-risk young people. Background: Being identified as 'at-risk' places an individual in danger of future negative outcomes. Conducting qualitative research such as narrative inquiry with 'at-risk' individuals has the potential for challenges to arise for participants and/or researchers. Discussion: Five main challenges identified and discussed were trauma disclosure, pre-existing relationships, insider/outsider perspective, power relationships and researcher and participant emotional safety. Conclusions: It is imperative that potential challenges be identified prior to the commencement of studies and plans made to address the challenges. Implication for practice: Difficulties can arise with any type of research involving vulnerable participants; hence as researchers we must always plan to ensure these challenges are managed appropriately
Lesbian women choosing motherhood: the journey to conception
Increasingly, lesbian women are choosing to have children in the context of a same-sex relationship, and their journey to conception and on to motherhood involves a range of decisions that are unique to lesbian couples. While creating a de novo family is burdened with decisions, choosing to be parents was a deliberate and conscious decision made by lesbian women participating in our study. The findings presented in this article focus on choosing which partner would be pregnant, donor decisions, as well as methods of conception used by lesbian women participating in a qualitative study that examined the experiences of lesbian mothers in Australia. This article is not intended to be interpretive, but rather a description of the processes engaged by participants
Influences on Healthcare-seeking during Final Illnesses of Infants in Under-resourced South African Settings
To examine how health caregivers in under-resourced South African settings select from among the healthcare alternatives available to them during the final illness of their infants, qualitative interviews were conducted with 39 caregivers of deceased infants in a rural community and an urban township. Nineteen local health providers and community leaders were also interviewed to ascertain opinions about local healthcare and other factors impacting healthcare-seeking choices. The framework analysis method guided qualitative analysis of data. Limited autonomy of caregivers in decision-making, lack of awareness of infant danger-signs, and identification of an externalizing cause of illness were important influences on healthcare-seeking during illnesses of infants in these settings. Health system factors relating to the performance of health workers and the accessibility and availability of services also influenced healthcare-seeking decisions. Although South African public-health services are free, the findings showed that poor families faced other financial constraints that impacted their access to healthcare. Often there was not one factor but a combination of factors occurring either concurrently or sequentially that determined whether, when, and from where outside healthcare was sought during final illnesses of infants. In addition to reducing health system barriers to healthcare, initiatives to improve timely and appropriate healthcare-seeking for sick infants must take into consideration ways to mitigate contextual problems, such as limited autonomy of caregivers in decision-making, and reconcile local explanatory models of childhood illnesses that may not encourage healthcare-seeking at allopathic services
Penalized Ordinal Regression Methods for Predicting Stage of Cancer in High-Dimensional Covariate Spaces
The pathological description of the stage of a tumor is an important clinical designation and is considered, like many other forms of biomedical data, an ordinal outcome. Currently, statistical methods for predicting an ordinal outcome using clinical, demographic, and high-dimensional correlated features are lacking. In this paper, we propose a method that fits an ordinal response model to predict an ordinal outcome for high-dimensional covariate spaces. Our method penalizes some covariates (high-throughput genomic features) without penalizing others (such as demographic and/or clinical covariates). We demonstrate the application of our method to predict the stage of breast cancer. In our model, breast cancer subtype is a nonpenalized predictor, and CpG site methylation values from the Illumina Human Methylation 450K assay are penalized predictors. The method has been made available in the ordinalgmifs package in the R programming environment
Walking alongside: a qualitative study of the experiences and perceptions of academic nurse mentors supporting early career nurse academics
Purpose: This study explores the experiences and perceptions of academic nurse mentors supporting early career nurse academics (ECNAs). Methods: Interviews were undertaken with mentors following a mentoring partnership with ECNAs. Data were transcribed verbatim and analysed using a process of thematic analysis. Findings: Four themes emerged from the data, namely; motivation for mentoring; constructing the relationship; establishing safe boundaries and managing expectations. Conclusions: This study provides a unique insight into the experiences of mentoring within the context of an academic leadership programme for nurses. Such insights highlight the issues facing academics from professional disciplines and can inform strategies to support their career development. Clinical relevance: A sustainable academic nursing workforce is crucial to ensure that effective preparation of future generations of expert clinical nurses. Therefore, it is important to consider strategies that could strengthen the academic nursing workforce
Unravelling the complexities of nursing students\u27 feedback on the clinical learning environment: a mixed methods approach
Background Clinical placement is an essential part of nursing education, and students\u27 experiences on clinical placement can affect the quality of their learning. Understanding nursing students\u27 positive and negative perceptions of clinical placement experience is therefore important. Objectives To describe nursing students\u27 satisfaction with their clinical placement experiences and identify any variations in satisfaction based on demographic characteristics. Design Mixed methods - online survey with qualitative items. Setting Four universities in Australia. Participants Students (n = 213) enrolled in an undergraduate nursing degree. Methods Between 2010 and 2012, students completed online surveys following their clinical placement experiences. The surveys included demographic questions and the Clinical Learning Environment Inventory (CLEI-19), a 19-item tool measuring students\u27 satisfaction with clinical placement. The surveys included two open-ended questions asking students to share their most satisfying and challenging experiences whilst on placement. Descriptive statistics and thematic analyses were undertaken. Results Of the 213 participants, those in health-related employment and those with English as an additional language (EAL) were less satisfied with the clinical facility and with clinical facilitator support respectively, as indicated by the CLEI-19 subscale scores. Qualitative findings showed students were positive about the opportunity to make a difference and be involved in nursing, and negative about clinical facilitator support. Nevertheless, those who were most critical in their written comments about their placement were those who only spoke English at home. Conclusions Although the study found overall satisfaction with clinical placement, the lower satisfaction reported by students in health-related employment, and the mixed findings regarding language spoken and satisfaction, warrant further attention
Influences on Healthcare-seeking during Final Illnesses of Infants in Under-resourced South African Settings
To examine how health caregivers in under-resourced South African
settings select from among the healthcare alternatives available to
them during the final illness of their infants, qualitative interviews
were conducted with 39 caregivers of deceased infants in a rural
community and an urban township. Nineteen local health providers and
community leaders were also interviewed to ascertain opinions about
local healthcare and other factors impacting healthcare-seeking
choices. The framework analysis method guided qualitative analysis of
data. Limited autonomy of caregivers in decision-making, lack of
awareness of infant danger-signs, and identification of an
externalizing cause of illness were important influences on
healthcare-seeking during illnesses of infants in these settings.
Health system factors relating to the performance of health workers and
the accessibility and availability of services also influenced
healthcare-seeking decisions. Although South African public-health
services are free, the findings showed that poor families faced other
financial constraints that impacted their access to healthcare. Often
there was not one factor but a combination of factors occurring either
concurrently or sequentially that determined whether, when, and from
where outside healthcare was sought during final illnesses of infants.
In addition to reducing health system barriers to healthcare,
initiatives to improve timely and appropriate healthcare-seeking for
sick infants must take into consideration ways to mitigate contextual
problems, such as limited autonomy of caregivers in decision-making,
and reconcile local explanatory models of childhood illnesses that may
not encourage healthcare-seeking at allopathic services
Epigenetic Alterations and an Increased Frequency of Micronuclei in Women with Fibromyalgia
Fibromyalgia (FM), characterized by chronic widespread pain, fatigue, and cognitive/mood disturbances, leads to reduced workplace productivity and increased healthcare expenses. To determine if acquired epigenetic/genetic changes are associated with FM, we compared the frequency of spontaneously occurring micronuclei (MN) and genome-wide methylation patterns in women with FM () to those seen in comparably aged healthy controls ( (MN); (methylation)). The mean (sd) MN frequency of women with FM (51.4 (21.9)) was significantly higher than that of controls (15.8 (8.5)) (; df = 1; ). Significant differences ( sites) in methylation patterns were observed between cases and controls considering a 5% false discovery rate. The majority of differentially methylated (DM) sites (91%) were attributable to increased values in the women with FM. The DM sites included significant biological clusters involved in neuron differentiation/nervous system development, skeletal/organ system development, and chromatin compaction. Genes associated with DM sites whose function has particular relevance to FM included BDNF, NAT15, HDAC4, PRKCA, RTN1, and PRKG1. Results support the need for future research to further examine the potential role of epigenetic and acquired chromosomal alterations as a possible biological mechanism underlying FM
An approach for evaluating early and long term mother-to-child transmission of HIV (MTCT) in low and middle income countries: a South African experience
Abstract
Background
Eliminating mother-to-child transmission of HIV is a global public health target. Robust, feasible methodologies to measure population level impact of programmes to prevent mother-to-child transmission of HIV (PMTCT) are needed in high HIV prevalence settings. We present a summary of the protocol of the South African PMTCT Evaluation (SAPMTCTE) with its revision over three repeated rounds of the survey, 2010â2014.
Methods
Three cross sectional surveys (2010, 2011â2012 and 2012â2013) were conducted in 580 primary health care immunisation service points randomly selected after stratified multistage probability proportional to size sampling. All infants aged 4â8âweeks receiving their six-week immunisation at a sampled facility on the day of the visit were eligible to participate. Trained research nurses conducted interviews and took infant dried blood spot (iDBS) samples for HIV enzyme immunoassay (EIA) and total nucleic acid polymerase chain reaction (PCR) testing. Interviews were conducted using mobile phones and iDBS were sent to the National Health Laboratory for testing. All findings were adjusted for study design, non-response, and weighted for number of South African live-birth in each study round. In 2012 a national closed cohort of these 4 to 8-week old infants testing EIA positive (HIV Exposed Infants) from the 2012â2013 cross-sectional survey was established to estimate longer-term PMTCT impact to 18âmonths. Follow-up analyses were to estimate weighted cumulative MTCT until 18âmonths, postnatal MTCT from 6âweeks until 18âmonths and a combined outcome of MTCT-or-death, using a competing risks model, with death as a competing risk. HIV-free survival was defined as a child surviving and HIV-negative up to 18âmonths or last visit seen. A weighted cumulative incidence analysis was conducted, adjusting for survey design effects.
Discussion
In the absence of robust high-quality routine medical recording systems, in the context of a generalised HIV epidemic, national surveys can be used to monitor PMTCT effectiveness; however, monitoring long-term outcomes nationally is difficult due to poor retention in care
In utero art exposure and birth and early growth outcomes among HIV-exposed uninfected infants attending immunization services: Results from national pmtct surveillance, South Africa
. Despite the recognized benefit of antiretroviral therapy (ART) for preventing and treating HIV, some studies have
reported adverse birth outcomes with in utero ART exposure. We evaluated the effect of infant in utero HIV and ART exposure on
preterm delivery (PTD), low birth weight (LBW), small for gestational age (SGA), and underweight for age (UFA) at 6 weeks.We surveyed 6179 HIV-unexposed-uninfected (HUU) and 2599 HIV-exposed-uninfected (HEU) infants. HEU infants
were stratified into 3 groups: ART, Zidovudine alone, and no antiretrovirals (None). The ART group was further stratified to explore
pre- or postconception exposure. Multivariable logistic regression evaluated effects of HIV and ARV exposure on the outcomes
