Assessing evidence-based practice among Australian radiographers: A self-report survey.

INTRODUCTION: Evidence-based practice (EBP) is essential for ensuring the delivery of effective and efficient healthcare. Despite this, EBP is not always well implemented in the clinical environment. Evidence suggests that the application of EBP is likely impacted by healthcare workers' attitudes, knowledge and skills. While there has been a recent proliferation of international research examining diagnostic radiographers' attitudes towards, knowledge of and skills in EBP, no such research exists in an Australian context. METHODS: This study presents the results of a validated self-report survey, the evidence-based practice questionnaire (EBPQ), administered to Australian diagnostic radiographers. The data were described and aggregated means were calculated for each of the domains. Inferential statistical tests were computed, including Cronbach's alpha, Pearson's correlations and independent t-tests, and Kruskal-Wallis tests. RESULTS: The aggregated mean for the practice domain was 5.02 (SD 1.104), for the attitudes domain it was 5.41 (SD 1.169), and for the knowledge and skills domain, it was 5.20 (SD 1.177) on a seven-point scale. Significant associations were identified among these domains, with individuals holding higher qualifications and occupying leadership positions more likely to score higher. Additionally, the modality in which an individual primarily practiced appeared to also have an impact on their score. However, no significant correlation was found between any domain and the number of years an individual had been practicing. CONCLUSION: This research has established a baseline of Australian diagnostic radiographers' practices, knowledge skills and attitudes towards evidence-based practice. IMPLICATIONS FOR PRACTICE: This baseline can inform the development of interventions aimed at enhancing the role of evidence-based practice in the sampled population.

Antibiotic resistance genes in the gut microbiota of mothers and linked neonates with or without sepsis from low- and middle-income countries.

Early development of the microbiome has been shown to affect general health and physical development of the infant and, although some studies have been undertaken in high-income countries, there are few studies from low- and middle-income countries. As part of the BARNARDS study, we examined the rectal microbiota of 2,931 neonates (term used up to 60 d) with clinical signs of sepsis and of 15,217 mothers screening for blaCTX-M-15, blaNDM, blaKPC and blaOXA-48-like genes, which were detected in 56.1%, 18.5%, 0% and 4.1% of neonates' rectal swabs and 47.1%, 4.6%, 0% and 1.6% of mothers' rectal swabs, respectively. Carbapenemase-positive bacteria were identified by MALDI-TOF MS and showed a high diversity of bacterial species (57 distinct species/genera) which exhibited resistance to most of the antibiotics tested. Escherichia coli, Klebsiella pneumoniae and Enterobacter cloacae/E. cloacae complex, the most commonly found isolates, were subjected to whole-genome sequencing analysis and revealed close relationships between isolates from different samples, suggesting transmission of bacteria between neonates, and between neonates and mothers. Associations between the carriage of antimicrobial resistance genes (ARGs) and healthcare/environmental factors were identified, and the presence of ARGs was a predictor of neonatal sepsis and adverse birth outcomes.

Oral health-related self-efficacy and fatalism in a regional South Australian Aboriginal population.

OBJECTIVES: To assess the psychometric properties, including face, content, criterion and known-groups validity and reliability, of scales to measure oral health-related self-efficacy and fatalism in a regional Aboriginal adult population in Australia. METHODS: Four hundred Aboriginal adults (aged 18-82 years, 67% female) completed a self-report questionnaire including items pertaining to oral health-related self-efficacy and fatalism. Structural validity was determined in exploratory factor analysis (EFA) with principal components analysis for each scale. Criterion validity was assessed between the instruments and theoretically related variables. Known-groups validity was investigated by comparing the scores in different population groups according to age, sex, education and employment. Reliability of the scales was assessed through internal consistency. RESULTS: The EFA confirmed a single factor structure for self-efficacy and fatalism scales, with Cronbach's alphas of 0.93 and 0.89 respectively. The two scales were not correlated. Oral health-related self-efficacy was associated with toothbrush ownership and brushing the previous day supporting criterion validity. Oral health-related fatalism was associated with previous extractions and perceived need for extractions also supporting criterion validity. Both measures were associated with social impact of oral health as measured by the OHIP-14, supporting their criterion validity. Mixed findings were observed in terms of known-groups validity. CONCLUSIONS: There was initial evidence that measures of oral health-related self-efficacy and fatalism displayed adequate psychometric properties in this Aboriginal community. These constructs could have implications for approaches for improving oral health among Aboriginal people.

Self-rated oral and general health among Aboriginal adults in regional South Australia.

BACKGROUND: In Australia, Aboriginal adults experience higher levels of poor oral and general health than the non-Aboriginal population. This study compared self-rated oral and general health among Aboriginal adults in regional South Australia with participants in the National Survey of Adult Oral Health (NSAOH). METHODS: Data were obtained from the Indigenous Oral Health Literacy Project (IOHLP) based in South Australia. Three sub-populations from the NSAOH were utilised for comparison: National Aboriginal, National non-Aboriginal and South Australian Regional Non-Aboriginal adults. All data were standardised by age group and sex, utilising Census data. RESULTS: Just over 70% of South Australian Regional Aboriginal participants gave a rating of 'excellent, very good or good' for general health, more than 17% lower than each of the other groups. Just over 50% rated their oral health highly, 20% fewer than the proportion for each other group. Stratifying by key socio-demographic factors did not account for all differences. CONCLUSIONS: Proportionally fewer South Australian Regional Aboriginal adults had high ratings of oral and general health than the Aboriginal and non-Aboriginal adults from the national survey, indicating that national-level data might underestimate the proportion of regional Aboriginal Australians with poor oral health.

From adolescence to parenthood: a multi-decade study of preconception mental health problems and postpartum parent-infant bonds.

PURPOSE: To examine associations between anxiety and depressive symptoms across adolescence and young adulthood with subsequent maternal- and paternal-infant bonding at 1 year postpartum. METHODS: The data were from a prospective, intergenerational cohort study. Participants (381 mothers of 648 infants; 277 fathers of 421 infants) self-reported depression and anxiety at three adolescent waves (ages 13, 15 and 17 years) and three young adult waves (ages 19, 23 and 27 years). Subsequent parent-infant bonds with infants were reported at 1 year postpartum (parent age 29-35 years). Generalised estimating equations (GEE) separately assessed associations for mothers and fathers. RESULTS: Mean postpartum bonding scores were approximately half a standard deviation lower in parents with a history of persistent adolescent and young adult depressive symptoms (maternal ßadj = - 0.45, 95% CI - 0.69, - 0.21; paternal ßadj = - 0.55, 95% CI - 0.90, 0.20) or anxiety (maternal ßadj = - 0.42, 95% CI - 0.66, - 0.18; paternal ßadj = - 0.49, 95% CI - 0.95, 0.03). Associations were still mostly evident, but attenuated after further adjustment for postpartum mental health concurrent with measurement of bonding. CONCLUSIONS: Persistent symptoms of depression or anxiety spanning adolescence and young adulthood predict poorer emotional bonding with infants 1-year postbirth for both mothers and fathers.

Experimental verification of principal losses in a regulatory particulate matter emissions sampling system for aircraft turbine engines.

A sampling system for measuring emissions of nonvolatile particulate matter (nvPM) from aircraft gas turbine engines has been developed to replace the use of smoke number and is used for international regulatory purposes. This sampling system can be up to 35 m in length. The sampling system length in addition to the volatile particle remover (VPR) and other sampling system components lead to substantial particle losses, which are a function of the particle size distribution, ranging from 50 to 90% for particle number concentrations and 10-50% for particle mass concentrations. The particle size distribution is dependent on engine technology, operating point, and fuel composition. Any nvPM emissions measurement bias caused by the sampling system will lead to unrepresentative emissions measurements which limit the method as a universal metric. Hence, a method to estimate size dependent sampling system losses using the system parameters and the measured mass and number concentrations was also developed (SAE 2017; SAE 2019). An assessment of the particle losses in two principal components used in ARP6481 (SAE 2019) was conducted during the VAriable Response In Aircraft nvPM Testing (VARIAnT) 2 campaign. Measurements were made on the 25-meter sample line portion of the system using multiple, well characterized particle sizing instruments to obtain the penetration efficiencies. An agreement of ± 15% was obtained between the measured and the ARP6481 method penetrations for the 25-meter sample line portion of the system. Measurements of VPR penetration efficiency were also made to verify its performance for aviation nvPM number. The research also demonstrated the difficulty of making system loss measurements and substantiates the E-31 decision to predict rather than measure system losses.

Childhood disadvantage and adolescent socioemotional wellbeing as predictors of future parenting behaviour.

INTRODUCTION: In extending work on early life antecedents of parenting, we investigate associations between childhood family history of disadvantage, adolescent socioemotional wellbeing, and age at first parenthood and subsequent parenting behaviour. METHODS: Parent-child interactions were recorded when participants in the longitudinal Dunedin Multidisciplinary Health and Development Study (New Zealand) had a three-year-old child. Data were available for 358 mothers and 321 fathers, aged between 17.7 and 41.5 at the time of their child's birth. Associations between parenting and antecedent data on socioeconomic disadvantage, adolescent wellbeing and mental health, as well as current adult mental health and age at parenting, were tested for using structural equation modelling. RESULTS: Family disadvantage in childhood and lower adolescent wellbeing was associated with less positive future parenting, but only adult (not adolescent) anxiety/depression symptoms were directly associated with parenting behaviour. Childhood family disadvantage was associated with further disadvantage across the life course that included less positive parenting of the next generation. In contrast, socioemotional wellbeing during adolescence and later age of onset of parenting were associated with more positive parenting. CONCLUSIONS: Reducing childhood disadvantage and improving socioemotional wellbeing during childhood and adolescence is likely to have intergenerational benefits through better parenting of the next generation.

Prevalence, Extent, and Severity of Oral Health Impacts Among Adults in Rural Karnataka, India.

INTRODUCTION: Oral health affects quality of life. Many studies have investigated the factors associated with oral health-related quality of life (OHRQoL). Little is known about OHRQoL of adults living in rural and remote areas of India, where many have lower levels of education and limited availability of oral health care services. OBJECTIVES: To determine the prevalence, extent, and severity of OHRQoL impacts associated with psychosocial factors, functional dentition, and patterns of dental visits among rural Indian adults between the ages of 35 and 54 y. METHODS: A cross-sectional study was conducted with a multistage stratified sampling strategy targeting 35- to 54-year-olds. Interviews and oral examinations were performed to collect data on sociodemographic variables, Oral Health Impact Profile-14 (OHIP-14), patterns of dental visits, stress, tobacco and alcohol use, and dentition status. Univariate, bivariate, and multivariable analyses were done to determine the factors associated with prevalence, extent, and severity of OHIP-14 using SAS version 9.3. RESULTS: There were 873 participants. Prevalence, extent, and severity of OHIP-14 were 13.4%, 0.5 (0.4-0.7), and 11.8 (11.2-12.5), respectively. The OHIP-14 impacts reported were not severe and mostly affected physical functioning. Levels of education, income, and number of functional teeth (FT) were inversely associated and last dental visit within the previous year was positively associated with prevalence, extent, and severity of OHIP-14. The prevalence of 1 or more oral health impacts was nearly 13% among rural middle-aged adults in India. CONCLUSIONS: Low socioeconomic conditions, dental visits, and FT ≤19 were positively associated with prevalence, extent, and severity of oral health impacts. KNOWLEDGE TRANSFER STATEMENT: This article provides data regarding OHRQoL of people in rural areas of a developing country. The study was intended to determine the factors associated with OHRQoL in rural people who are less educated and living in areas with minimal oral health care facilities. The findings of this study could potentially facilitate further research and health promotional activities for rural people of developing countries.

Exploring a causal model in observational cohort data: The role of parents and peers in shaping substance use trajectories.

AIMS: To explore the process of applying counterfactual thinking in examining causal determinants of substance use trajectories in observational cohort data. Specifically, we examine the extent to which quality of the parent-adolescent relationship and affiliations with deviant peers are causally related to trajectories of alcohol, tobacco, and cannabis use across adolescence and into young adulthood. METHODS: Data were drawn from the Australian Temperament Project, a population-based cohort study that has followed a sample of young Australians from infancy to adulthood since 1983. Parent-adolescent relationship quality and deviant peer affiliations were assessed at age 13-14 years. Latent curve models were fitted for past month alcohol, tobacco, and cannabis use (n = 1590) from age 15-16 to 27-28 years (5 waves). Confounding factors were selected in line with the counterfactual framework. RESULTS: Following confounder adjustment, higher quality parent-adolescent relationships were associated with lower baseline cannabis use, but not alcohol or tobacco use trajectories. In contrast, affiliations with deviant peers were associated with higher baseline binge drinking, tobacco, and cannabis use, and an earlier peak in the cannabis use trajectory. CONCLUSIONS: Despite careful application of the counterfactual framework, interpretation of associations as causal is not without limitations. Nevertheless, findings suggested causal effects of both parent-adolescent relationships and deviant peer affiliations on the trajectory of substance use. Causal effects were more pervasive (i.e., more substance types) and protracted for deviant peer affiliations. The exploration of causal relationships in observational cohort data is encouraged, when relevant limitations are transparently acknowledged.

Microplastics in the edible tissues of shellfishes sold for human consumption.

Microplastics in seafood are an emerging area of seafood safety concern. In this study, we investigated the presence of microplastics (100 µm - 5 mm) in the edible tissues of four species of shellfishes - two species of shrimp, Metapenaeus dobsoni and Fenneropenaeus indicus; one species of crab, Portunus pelagicus; and one species of squid Uroteuthis (Photololigo) duvaucelii -all bought from fishing harbours of Kerala, India. An average of 2.7 ± 12 microplastic particles kg-1 of edible tissue (wet weight) and 0.07 ± 0.3 microplastic particles/individual were obtained from the sampled shellfishes. No microplastics were found in the edible tissues of shrimps examined, while U. (P) duvaucelii had the highest microplastic content with an average of 7.7 ± 20 microplastic particles kg-1 of edible tissue, followed by P. pelagicus with an average of 3.2 ± 10 microplastic particles kg-1 of edible tissue. There was significant species variation in the microplastic contamination of shellfish soft tissues (p < 0.05). The study is the first of its kind to report the detection of microplastics in edible tissues of a squid species. Results suggested an annual dietary intake of about 13 ± 58 microplastic particles per year by shellfish consumers, which can vary based on the species, quantity, and extent of gut removal of seafood consumed.

Knowledge translation: Radiographers compared to other healthcare professionals.

OBJECTIVES: This narrative review examines the current status of evidence-based practice and knowledge translation in diagnostic radiography. It explores knowledge translation efforts in the allied health professions aimed at systematically implementing evidence-based practice and suggests ways that these may be applied within diagnostic radiography. KEY FINDINGS: Knowledge translation in diagnostic radiography is in its infancy with numerous examples of key findings of rigorous studies not implemented in practice. Utilising frameworks, models and theories to systematically translate knowledge into evidence-based practice has been shown to be effective in other allied health professions. Whilst few studies in diagnostic radiography report utilising these systematic approaches to implementing evidence-based practice, those that do, show promising results. Attitudes towards evidence-based practice within diagnostic radiography are becoming more positive and it is important to use this positive shift in attitudes to create real evidence-based change in the profession. CONCLUSION: The potential benefits of systematically translating knowledge into evidence-based practice in diagnostic radiography are wide reaching with positive implications for our patients, the profession and wider community. Leaders at all levels of radiography must work towards implementing evidence-based practice in their daily work. IMPLICATIONS FOR PRACTICE: Systematic approaches to knowledge translation should be adopted and reported in diagnostic radiography in order to more effectively translate knowledge into evidence-based practice.

Evaluating temporal patterns of metals concentrations in floodplain lakes of the Athabasca Delta (Canada) relative to pre-industrial baselines.

Sediment quality monitoring is widely used to quantify extent of river pollution, but requires knowledge of pre-disturbance conditions in the potentially altered landscape. This has long been identified as a critical aspect to develop for addressing concerns of river pollution in the Alberta Oil Sands Region. Here, we use analyses of sediment cores from eight floodplain lakes spanning a 67 river-km transect across the Athabasca Delta to define pre-1920 (pre-industrial) baseline concentrations for vanadium and five primary pollutants. We then evaluate if sediment metals concentrations have become enriched above baseline since onset of oil sands development and other industrial activities. Results demonstrate no enrichment of metals concentrations (except zinc at one lake) and absence of consistent temporal increases above pre-industrial baselines. Thus, natural processes continue to dominate metal deposition in floodplain lakes of the Athabasca Delta -- an important finding to inform stewardship decisions. The pre-1920 metals concentrations baselines offer a useful tool for ongoing sediment monitoring in aquatic ecosystems of the Athabasca Delta.

Assessment of fishing-related plastic debris along the beaches in Kerala Coast, India.

An assessment of quantity, composition and seasonal variation of fishing-related plastic debris was conducted in six beaches along the Kerala coast of India during 2017-2018. Plastic items were the most dominant type of waste constituting 73.8% by number and 59.9% by weight. In the total debris recorded, 5540 pieces (36%) weighing 198.4 kg (39.8%) were fishing related trash. On an average 14.4 ±â€¯12 fishing related items/100 m2, corresponding to mean weight of 0.55 ±â€¯0.7 kg/100 m2 was recorded from these beaches. Results indicated that the fishing-related plastic items were concentrated four times more in the beaches with higher fishing intensity, as compared to the other beaches. Also, the concentration of fishing-related plastic was recorded higher in the post-monsoon season compared to the lowest during monsoon, which was significant with p-value < 0.05. The results emphasize the role of fishing activities in the generation of marine litter.

Community trial of silver fluoride treatment for deciduous dentition caries in remote Indigenous communities.

BACKGROUND: Silver fluoride 40% followed by 10% stannous fluoride (AgF) has been used in dental practice in some parts of Australia for many years. This study compared the effectiveness of application of AgF with atraumatic restorative technique (ART) in managing cavitated carious primary molars. METHODS: The study was a community effectiveness trial in two remote Aboriginal communities where AgF has been used for some time. Children between 4 and 8 years of age with caries on primary molars were randomized by birth date to receive AgF or ART. There were 210 children who were included in the study with 384 eligible teeth. Children were followed up for periods between 9 months and 4 years. Negative outcomes such as dental pain, extraction, use of antibiotics and more extensive restorative treatment were considered as the primary outcomes of the study. RESULTS: Those negative outcomes were infrequent in both treatment groups. The prevalence ratio of negative sequelae for children treated with AgF compared with those treated with ART was lower at 0.18. CONCLUSIONS: Silver fluoride was well accepted, easy to use and at least as effective a treatment as ART for dental caries in primary molars in young Aboriginal children in remote areas.

Risk indicators for prevalence, extent and severity of periodontitis among rural Indian population aged 35-54 years.

AIMS: This study aimed to identify risk indicators associated with periodontitis and the contribution of each of the indicators towards the prevalence, extent and severity of periodontitis in a rural Indian population. METHODS: A cross-sectional study design was used to collect data according to National Survey of Adult Oral Health Australia guidelines. A multistage stratified random sampling was followed to select 1401 participants, who were in the age group of 35-54 years. The participants were selected from 50 villages belonging to the 5 sub-provinces of 2 Indian districts. Data were collected through face-to-face interviews and oral examination. Statistical analysis was performed using SAS version 9.3. The univariate, bivariate and multivariate analyses were performed to determine the risk indicators of prevalence, extent and severity of periodontitis. Population attributable fraction was estimated for each of the significant risk indicators of prevalence and extent. RESULTS: In this study, factors such as age, education, tobacco chewing and plaque accumulation were significantly associated with the prevalence of periodontitis. Age, socioeconomic status, method of tooth cleaning, alcohol consumption and plaque accumulation were significant risk indicators for generalized periodontitis. Age, tobacco chewing and plaque were associated with severity of periodontitis in the population. CONCLUSION: The rural population had a high prevalence of periodontitis. Sociodemographic factors, poor oral hygiene, tobacco and alcohol were the main risk indicators attributable to periodontitis.

Race- and Income-Related Inequalities in Oral Health in Australian Children by Fluoridation Status.

Inequality in child oral health exists by race and income. Water fluoridation (WF) is effective in caries prevention, but evidence for WF reducing inequality in caries experience is equivocal. This study tested the hypothesis that WF reduces race- and income-related inequality in child caries experience. A cross-sectional national population-based study of child oral health was conducted across 2012 to 2014 for Australian children aged 5 to 14 y, involving a parental questionnaire and an oral epidemiological examination. Children were stratified by fluoridated (F) and nonfluoridated (NF) area of residence, equivalized household income quartiles, and Indigenous and non-Indigenous status. Directly standardized caries experience (measured by the decayed, missing, or filled tooth surfaces [dmfs/DMFS] in both primary [age 5-10] and permanent dentitions [age 9-14]) was estimated for each stratum accounting for the complex sampling design. Differences in caries experience by Indigenous status and equivalized income quartiles were examined between F and NF strata. Socioeconomic inequality in caries experience was examined using the Absolute Concentration Index (ACI), Slope Index of Inequality (SII), Relative Concentration Index (RCI), and Relative Index of Inequality (RII). A total of 21,328 (86.5%) children had complete data. Caries experience was higher in NF than F strata. Race- and income-related gradients in caries experience were observed in both F and NF areas. All indexes of inequality indicated that caries experience was concentrated among lower income groups. Absolute inequalities were consistently lower in F than in NF areas. For the primary dentition, SII values were -4.18 versus -6.20 in the F and NF areas, respectively. The respective values were -0.60 versus -1.66 for the permanent dentition. Income-related inequality in caries was lower in F than in NF areas for both Indigenous and non-Indigenous children. WF was associated with lower caries experience and reduced inequality among children. Knowledge Transfer Statement: The results of this study greatly increase the evidence base that water fluoridation is effective and socially equitable. Dental caries has remained one of the most prevalent chronic conditions in children worldwide. The presented evidence can be used by policy makers and the profession to support the maintenance or expansion of this important public health program to benefit those most at risk of dental caries, the groups at the lowest socioeconomic position in any society.

Reducing Potentially Preventable Dental Hospitalizations of Young Children: A Community-Level Analysis.

An increasing number of Australians are being admitted to hospitals and day procedure centers to have dental treatment under a dental general anesthetic (DGA). Children younger than 2 y are having DGAs. These operations are costly and, although there have been improvements in safety, are not without risk. Most DGAs in children are to treat dental caries and have been defined as potentially preventable dental hospitalizations (PPDHs). This article reports on an analysis of the impact of access to community water fluoridation (CWF), availability of oral health professionals (OHPs), and socioeconomic status (SES) on PPDHs of 0- to 4-y-olds in 2012-2013 in Victoria, Australia. Data on these variables were obtained at the community (postcode) level. From the negative binomial multivariate analysis, each of the 3 independent variables was independently significantly associated with PPDHs at the postcode level. Children residing in postcodes without CWF on average had 59% higher rates than those with access (incident rate ratio [IRR], 1.59; P < 0.0001), children in postcodes with the lowest level of availability of OHPs had 65% higher rates than those with the highest access (IRR, 1.65; P < 0.0001), and children living in the most disadvantaged SES quintiles had 57% higher rates than children in the most advantaged quintiles (IRR, 1.57; P < 0.0001). There was a stepwise social gradient by SES quintile. In analysis of access to CWF and SES status, children without access to CWF had 86% higher PPDH rates than children with access (IRR, 1.86; P < 0.0001). In summary, no access to CWF, poor availability of OHPs, and lower SES status were independently associated with higher PPDH rates among 0- to 4-y-olds in Victoria at the postcode level. The study highlights the importance of considering 3 interacting factors-access to CWF, access to OHPs, and SES-in efforts to reduce PPDH rates in young children. Knowledge Transfer Statement: Extending access to water fluoridation, increasing the availability of dental services, and raising disadvantaged families' socioeconomic status are each likely to decrease the rate of dental general anesthetics in young children.

Salvage high-dose chemotherapy in female patients with relapsed/refractory germ-cell tumors: a retrospective analysis of the European Group for Blood and Marrow Transplantation (EBMT).

BACKGROUND: High-dose chemotherapy (HDC) with hematopoietic progenitor cell transplantation is a standard option for relapsed/refractory testicular germ-cell tumor (GCT), but only few data have been reported in female patients with GCT. We conducted a retrospective analysis of female patients with GCT treated with HDC and registered with the European Society for Blood and Marrow Transplantation. PATIENTS AND METHODS: Between 1985 and 2013, 60 registered female patients with GCT, median age 27 years (range 15-48), were treated with salvage HDC. Forty patients (67%) had primary ovarian GCT, 8 (13%) mediastinal, 7 (12%) retroperitoneal and 5 (8%) other primary sites/unknown. Twenty-two patients (37%) received HDC as second-line therapy, 29 (48%) as third-line, and 9 (15%) as fourth- to sixth-line. Nine of 60 patients (15%) received HDC as late-intensification with no evidence of metastasis before HDC. The conditioning HDC regimens comprised carboplatin in 51 of 60 cases (85%), and consisted of a single HDC cycle in 31 cases (52%), a multi-cycle HDC regimen in 29 (48%). RESULTS: Nine cases who underwent late intensification HDC were not evaluable for response. Of the other 51 assessable patients, 17 (33%) achieved a complete response (CR), 8 (16%) a marker-negative partial remission (PRm-), 5 (10%) a marker-positive partial remission, 5 (10%) stable disease, and 13 (25%) progressive disease. There were 3 toxic deaths (6%). With an overall median follow-up of 14 months (range 1-219), 7 of 9 (78%) patients with late intensification and 18 of the 25 patients (72%) achieving a CR/PRm- following HDC were free of relapse/progression. In total, 25 of 60 patients (42%) were progression-free following HDC at a median follow-up of 87 months (range 3-219 months). CONCLUSIONS: Salvage HDC based on carboplatin represents a therapeutic option for female patients with relapsed/refractory GCT.
