Cervical cancer care at a tertiary oncology facility in Uganda: Comparing daily practice with national treatment targets on cervical cancer control
2025
Treatment of cervical cancer patients in Uganda is hampered by late diagnosis due to the unavailability of timely screening and limited availability of advanced cancer care. This study evaluated the clinical presentation and management of cervical cancer patients presenting at the Uganda Cancer Institute (UCI) in Kampala, the tertiary oncology facility in Uganda with access to radiotherapy and reflected on daily clinical practice to identify priority areas for improving cervical cancer care in Uganda.
We retrospectively analyzed medical records of all cervical cancer patients presenting to UCI between January 2017 and March 2018 for sociodemographic characteristics and clinical variables with descriptive statistics. The clinical management of patients with early and advanced stage disease who initiated treatment at UCI was evaluated using the national targets formulated in the Uganda strategic plan for cervical cancer prevention and control.
Medical records of 583 patients were included, representing less than 10% of the annual estimated incidence in Uganda. The majority (86%) of patients presented with advanced stage of disease. More than half of patients never initiated (31%) or interrupted (30%) treatment. The national treatment targets for surgery (10%) and palliative care (25%) were achieved for eligible patients at UCI, however, the target for chemoradiotherapy (65%) was not met.
Daily clinical practice differed from the ambitions formulated in the national treatment targets on cervical cancer control. While most women presented in advanced stage requiring chemoradiotherapy, the target was not met due to limited availability of radiotherapy. Although targets for surgery and palliative care were achieved at UCI facility level, they mask the unmet need of the majority of cervical cancer patients who never initiated or completed treatment. This demands for further expansion of oncological surgical capacity, chemotherapy and radiotherapy and warrants to focus on accessible prevention programs.

Background
Current postgraduate medical training programmes fall short regarding residents’ development of generic competencies (communication, collaboration, leadership, professionalism) and reflective and deliberate practice. Paying attention to these non-technical skills in a structural manner during postgraduate training could result in a workforce better prepared for practice. A development-oriented performance assessment (PA), which assists residents with assessment of performance and deliberately planned learning activities, could potentially contribute to filling this gap. This study aims to explore residents experiences with the PA.
Methods
We conducted a qualitative interview study with 16 residents from four different medical specialties who participated in the PA, scheduled halfway postgraduate training. The PA was conducted by an external facilitator, a psychologist, and focused specifically on professional development and career planning. Residents were interviewed 6 months after the PA. Data were analysed using the framework method for qualitative analysis.
Results
Residents found the PA to be of additional value for their training. The overarching merit was the opportunity to evaluate competencies not usually addressed in workplace-based assessments and progress conversations. In addition, the PA proved a valuable tool for assisting residents with reflecting upon their work and formulating their learning objectives and activities. Residents reported increased awareness of capacity, self-confidence and enhanced feelings of career-ownership. An important factor contributing to these outcomes was the relationship of trust with the facilitator and programme director.
Conclusion
The PA is a promising tool in fostering the development of generic competencies and reflective and deliberate practice. The participating residents, facilitator and programme directors were able to contribute to a safe learning environment away from the busy workplace. The facilitator plays an important role by providing credible and informative feedback. Commitment of the programme director is important for the implementation of developmental plans and learning activities.

Noninvasive fetal aneuploidy detection by use of free DNA from maternal plasma has recently been shown to be achievable by whole genome shotgun sequencing. The high-throughput next-generation sequencing platforms previously tested use a PCR step during sample preparation, which results in amplification bias in GC-rich areas of the human genome. To eliminate this bias, and thereby experimental noise, we have used single molecule sequencing as an alternative method.
For noninvasive trisomy 21 detection, we performed single molecule sequencing on the Helicos platform using free DNA isolated from maternal plasma from 9 weeks of gestation onwards. Relative sequence tag density ratios were calculated and results were directly compared to the previously described Illumina GAII platform.
Sequence data generated without an amplification step show no GC bias. Therefore, with the use of single molecule sequencing all trisomy 21 fetuses could be distinguished more clearly from euploid fetuses.
This study shows for the first time that single molecule sequencing is an attractive and easy to use alternative for reliable noninvasive fetal aneuploidy detection in diagnostics. With this approach, previously described experimental noise associated with PCR amplification, such as GC bias, can be overcome.

Background
CenteringPregnancy (CP) is a multifaceted group based care-model integrated in routine prenatal care, combining health assessment, education, and support. CP has shown some positive results on perinatal outcomes. However, the effects are less obvious when limited to the results of randomized controlled trials: as there are few trials and there is a variation in reported outcomes. Furthermore, former research was mostly conducted in the United States of America and in specific (often high risk) populations. Our study aims to evaluate the effects of CP in the Netherlands in a general population of pregnant women (low and high risk). Furthermore we aim to explore the mechanisms leading to the eventual effects by measuring potential mediating factors.
Design
We will perform a stepped wedge cluster randomized controlled trial, in a Western region in the Netherlands. Inclusion criteria are <24 weeks of gestation and able to communicate in Dutch (with assistance). Women in the control period will receive individual care, women in the intervention period (starting at the randomized time-point) will be offered the choice between individual care or CP. Primary outcomes are maternal and neonatal morbidity, retrieved from a national routine database. Secondary outcomes are health behavior, psychosocial outcomes, satisfaction, health care utilization and process outcomes, collected through self-administered questionnaires, group-evaluations and individual interviews. We will conduct intention-to-treat analyses. Also a per protocol analysis will be performed comparing the three subgroups: control group, CP-participants and non-CP-participants, using multilevel techniques to account for clustering effects.
Discussion
This study contributes to the evidence regarding the effect of CP and gives a first indication of the effect and implementation of CP in both low and high-risk pregnancies in a high-income Western society other than the USA. Also, measuring factors that are hypothesized to mediate the effect of CP will enable to explain the mechanisms that lead to effects on maternal and neonatal outcomes.

ObjectiveTo gain insight into programme directors’ (PDs’) perceptions of trainee attrition from postgraduate medical education (PGME), focusing on interactions between stakeholders within the learning environment and roles of PDs in the process leading to attrition.Design, setting and participantsWe performed a focus group study with 27 PDs from three Dutch teaching hospitals and analysed transcripts using template analysis.ResultsPDs identified attrition as a multilevel problem, in which personal, workplace and system-bound factors play a role. PDs mentioned balancing professional and personal responsibilities, in particular parenthood and high ambitions, as important trainee-related factors. PDs adopt different, at times conflicting, roles when guiding trainees, for example, assessor and mentor, and they struggle to balance these roles. They displayed various emotions when discussing attrition, varying from disappointment to frustration and anger, yet could also frame attrition positively as new opportunity. PDs used numerous resources to support trainees in difficulty, in a reactive rather than in a pro-active manner. A generation difference between faculty and trainees regarding work-life balance was mentioned as impeding mutual understanding. On the system level, PDs observed how implicit beliefs and negative interactions between actors in the learning environment impede trainees’ well-being.ConclusionsPDs perceived trainee attrition as a multi-level problem that highlighted conflicting roles for the PD and evoked a wide range of emotions. The authors propose the following interventions: (1) address conflicting roles of PDs by reallocating specific tasks to other independent ‘third parties’, for example, professional coaching; (2) implement pro-active support for trainees unrelated to assessment; (3) create awareness of implicit assumptions of stakeholders and promote social belonging; (4) foster a supportive learning climate with clinical leaders as role models.

ObjectivesTo compare the Optimality Index of planned birth in a birth centre with planned birth in a hospital and planned home birth for low-risk term pregnant women who start labour under the responsibility of a community midwife.DesignProspective cohort study.SettingLow-risk pregnant women under care of a community midwife and living in a region with one of the 21 participating Dutch birth centres or in a region with the possibility for midwife-led hospital birth. Home birth was commonly available in all regions included in the study.Participants3455 low-risk term pregnant women (1686 nulliparous and 1769 multiparous) who gave birth between 1 July 2013 and 31 December 2013: 1668 planned birth centre births, 701 planned midwife-led hospital births and 1086 planned home births.Main outcome measurementsThe Optimality IndexNL-2015, a tool to measure ‘maximum outcome with minimal intervention’, was assessed by planned place of birth being a birth centre, a hospital setting or at home. Also, a composite maternal and perinatal adverse outcome score was calculated for the different planned places of birth.ResultsThere were no differences in Optimality Index NL-2015 for pregnant women who planned to give birth in a birth centre compared with women who planned to give birth in a hospital. Although effect sizes were small, women who planned to give birth at home had a higher Optimality Index NL-2015 than women who planned to give birth in a birth centre. The differences were larger for multiparous than for nulliparous women.ConclusionThe Optimality Index NL-2015 for women with planned birth centre births was comparable with planned midwife-led hospital births. Women with planned home births had a higher Optimality Index NL-2015, that is, a higher sum score of evidence-based items with an optimal value than women with planned birth centre births.

Why do trainees leave hospital-based specialty training? A nationwide survey study investigating factors involved in attrition and subsequent career choices in the Netherlands
2019
ObjectiveTo gain insight into factors involved in attrition from hospital-based medical specialty training and future career plans of trainees who prematurely left their specialty training programme.DesignNationwide online survey study.SettingPostgraduate education of all hospital-based specialties in the Netherlands.Participants174 trainees who prematurely left hospital-based medical specialty training between January 2014 and September 2017.Main outcome measuresFactors involved in trainees’ decisions to leave specialty training and their subsequent career plans.ResultsThe response rate was 38%. Of the responders, 25% left their programme in the first training year, 50% in year 2–3 and 25% in year 4–6. The most frequently reported factors involved in attrition were: work-life balance, job content, workload and specialty culture. Of the leaving trainees, 66% switched to another specialty training programme, of whom two-thirds chose a non-hospital-based training programme. Twelve per cent continued their career in a non-clinical role and the remainder had no specific plans yet.ConclusionsThis study provides insight in factors involved in attrition and in future career paths. Based on our findings, possible interventions to reduce attrition are: (1) enable candidates to develop a realistic view on job characteristics and demands, prior to application; (2) provide individual guidance during specialty training, with emphasis on work-life balance and fit with specialty.

Chromosome Aberrations
2014
Genomic microarray analysis is increasingly being applied as a prenatal diagnostic tool. Microarrays enable searching the genome at a higher resolution and with higher sensitivity than conventional karyotyping for identifying clinically significant chromosomal abnormalities. As yet, no clear guidelines exist on whether microarrays should be applied prenatally for all indications or only in selected cases such as ultrasound abnormalities, whether a targeted or genome-wide array should be used, and what these should include exactly. In this paper, we present some ethical considerations on the prenatal use of microarrays. There is a strong consensus, at least in Western countries, that the aim of prenatal screening for foetal abnormalities should be understood as facilitating autonomous reproductive choice for prospective parents. The tests offered should be valid and useful to reach that purpose. Against this background, we address several ethical issues raised by the prenatal application of microarrays. First, we argue that the general distinction between a targeted and a genome-wide microarray needs to be scrutinised. Then we examine whether microarrays are ‘suitable tests’ to serve either a screening or a diagnostic purpose. Given the wide range of findings possibly generated by microarrays, the question arises whether microarrays actually promote or interfere with autonomous reproductive decision-making. Moreover, if variants of unknown clinical significance are identified, this adds to the burden and complexity of reproductive decision-making. We suggest a qualified use of microarrays in the prenatal context.

In this multicenter, randomized trial, internal tocodynamometry was compared with external monitoring of uterine activity in women with induced or augmented labor. The use of internal tocodynamometry did not reduce the rate of operative deliveries or improve other maternal or neonatal outcomes.
Internal tocodynamometry was compared with external monitoring of uterine activity in women with induced or augmented labor. The use of internal tocodynamometry did not reduce the rate of operative deliveries or improve other maternal or neonatal outcomes.
The monitoring of uterine contractions by means of internal tocodynamometry during induction or augmentation of labor is advocated by professional societies in obstetrics and gynecology. Induction or augmentation is necessary in approximately 20% of all deliveries, and internal monitoring is thought to quantify the frequency, duration, and magnitude of uterine activity more accurately than does external tocography.

Purpose
Congenital heart defects (CHD) are associated with genetic syndromes. Rapid aneuploidy testing and chromosome microarray analysis (CMA) are standard care in fetal CHD. Many genetic syndromes remain undetected with these tests. This cohort study aims to estimate the frequency of causal genetic variants, in particular structural chromosome abnormalities and sequence variants, in fetuses with severe CHD at mid-gestation, to aid prenatal counselling.
Methods
Fetuses with severe CHD were extracted from the PRECOR registry (2012–2016). We evaluated pre- and postnatal genetic testing results retrospectively to estimate the frequency of genetic diagnoses in general, as well as for specific CHDs.
Results
919 fetuses with severe CHD were identified. After exclusion of 211 cases with aneuploidy, a genetic diagnosis was found in 15.7% (111/708). These comprised copy number variants in 9.9% (70/708). In 4.5% (41/708) sequence variants were found that would have remained undetected with CMA. Interrupted aortic arch, pulmonary atresia with ventricular septal defect and atrioventricular septal defect were most commonly associated with a genetic diagnosis.
Conclusion
In case of normal CMA results, parents should be offered exome sequencing sequentially, if time allows for it, especially if the CHD is accompanied by other structural malformations due to the large variety in genetic syndromes.
