Curatorship applications: The role of neuropsychology.

This article highlights ethical issues that may arise in the relationship between curatorship applications and neuropsychology. In South Africa (SA), curatorship applications for the elderly diagnosed with dementia require substantiation from two medical professionals, one of whom should be a practising psychiatrist deemed competent to provide this. Concurrently, there is often a request for a psychologist to conduct a neuropsychological assessment and to produce a relevant report. The process may result in ethical issues at various stages of the assessment. The balance between protecting the patient's rights v. freedom of autonomy becomes a central issue. Psychiatrists and psychologists are cautioned to adhere to best practices throughout the assessment, maintaining a critical and reflective stance. The limitations of cognitive assessment as a predictor of functionality should be considered. Furthermore, neuropsychological training in SA differs across institutions, resulting in variable practitioner competency. 'Competency' itself is an ambiguous legal term that may be interpreted variably. This article outlines the definitions and requirements of the curatorship process, as well as the role and limitations of neuropsychology, with emphasis on the ethical dilemmas that may arise.

The Association of Clinical Characteristics and Tumour Markers With Image-Defined Risk Factors in the Management of Neuroblastoma in South Africa.

AIMS: Image-defined risk factors (IDRFs) in neuroblastoma predict surgical complications and management outcomes. As there is a lack of data regarding the association of IDRFs with clinical and pathological factors, this study evaluated the prognostic value of IDRFs to predict neuroblastoma survival outcomes. MATERIALS AND METHODS: This was a retrospective study including 345 patients and reviewed diagnostic imaging for 20 IDRFs, pleural effusions and ascites. The IDRFs were grouped into five 'primary IDRFs' cohorts with vascular encasement, involvement of multiple body compartments, organ infiltration, airway obstruction and intraspinal extension. The association between clinical, histopathological and biological characteristics of neuroblastoma and management was evaluated. RESULTS: More patients without IDRFs had operations compared with patients with IDRFs, with a trend towards significance (64.4% versus 35.6%, P = 0.082). Patients with multiple compartment tumour involvement (P = 0.003) and organ infiltration (P < 0.001) had a higher risk of surgical complications. The 5-year overall survival of the group with more than one IDRF was 0.0% and those with pleural effusions or ascites 6.7%, associated with the worst outcome (P = 0.005). The total number of IDRFs was not predictive of the metastatic remission rate (P = 0.585) or overall survival (P = 0.142), with no conclusive association found between IDRF groups and clinical or biological markers. CONCLUSIONS: Patients with more than one IDRF had the shortest survival time, whereas those with pleural effusions and ascites at diagnosis had a poor outcome. Standardised reporting of IDRFs is crucial for predicting prognosis.

Determinants of diarrhoeal disease in children living in low-income households in a periurban community in Cape Town, South Africa

Background. Water, sanitation and hygiene are critically important in reducing morbidity and mortality from childhood diarrhoeal disease and malnutrition in low-income settings.Objectives. To assess the association of diarrhoeal disease with factors relating to domestic hygiene, the environment, sociodemographic status and anthropometry in children <2 years of age.Methods. This was a case-control study conducted in a periurban community 35 km from the centre of Cape Town, South Africa. The study included 100 children with diarrhoeal disease and 100 age-matched controls without diarrhoea, who were recruited at primary healthcare clinics. Sociodemographic status, environmental factors and domestic hygiene were assessed using a structured questionnaire; anthropometry was assessed using the World Health Organization's child growth standards. Univariate and multivariate logistic regression analyses were performed to identify the factors associated with diarrhoea. Results. The results of the univariate logistic regression showed significant susceptibility to diarrhoea in study cases compared with controls when the caregiver was ≥25 years old (odds ratio (OR) 1.82; 95% confidence interval (CI) 1.02 - 3.23; p=0.042); when children were in day care or cared for by a family member or a relative than when cared for by their mother (OR 1.97; 95% CI 1.06 - 3.65; p=0.032); and when the mothers were employed rather than at home (OR 2.23; 95% CI 1.21 - 4.12; p=0.01). Multivariate logistic regression analysis was used to identify predictors of diarrhoea, which entailed relaxing the inclusion criteria for the univariate analysis variables (p<0.25). The predictors significantly associated with diarrhoea were household problems relating to rat infestation (OR 2.44; 95% CI 1.13 - 5.28; p=0.027); maternal employment (OR 2.47; 95% CI 1.28 - 4.76; p=0.007); and children in day care or cared for by a relative (OR 2.34; 95% CI 1.21 - 4.54; p=0.01). Significantly more of the mothers who were employed than those who were unemployed had children in day care or cared for by a relative. Conclusion. Practices relating to employment, childcare and the domestic environment were significant predictors of diarrhoea. Effective policy implementation on water, sanitation and domestic hygiene could prevent diarrhoeal disease and reduce its impact on children's growth, especially during the annual diarrhoeal surge season in this and similar periurban communities.

The Association between Tumour Markers and Meta-iodobenzylguanidine Scans in South African Children with High-risk Neuroblastoma.

AIMS: Diagnostic and post-induction 123I-meta-iodobenzylguanidine (123I-mIBG) scans have prognostic significance in the treatment of neuroblastoma, but data from low- and middle-income countries are limited due to resource constraints. The aim of this study was to determine the association between neuroblastoma-associated tumour markers (lactate dehydrogenase [LDH], ferritin and MYCN amplification) and 123I-mIBG scans (modified Curie scores and metastatic disease patterns) in predicting complete metastatic response rates (mCR) and overall survival. MATERIALS AND METHODS: Two hundred and ninety patients diagnosed with high-risk neuroblastoma in South Africa between January 2000 and May 2018 and a subanalysis of 78 patients with diagnostic 123I-mIBG scans were included. Data collection included LDH, ferritin and MYCN amplification at diagnosis. Two nuclear physicians independently determined the modified Curie scores and pattern of distribution for each diagnostic and post-induction 123I-mIBG scans with high inter-rater agreement (r = 0.952) and reliability (K = 0.805). The cut-off values for the diagnostic and post-induction modified Curie scores of ≥7.0 (P = 0.026) and 3 (P = 0.009), respectively, were generated. The association between the tumour markers and the modified Curie score of the 123I-mIBG scans was determined using post-induction mCR and 2-year overall survival. RESULTS: Diagnostic LDH (P < 0.001), ferritin (P < 0.001) and the diagnostic modified Curie scores (P = 0.019) significantly predicted mCR. Only ferritin correlated with diagnostic modified Curie scores (P = 0.003) but had a low correlation coefficient of 0.353. On multivariable analysis, the only significant covariate for 2-year overall survival at diagnosis was LDH <750 U/l (P = 0.024). A post-induction chemotherapy modified Curie score ≤3.0 had a 2-year overall survival of 46.2% compared with 30.8% for a score >3.0 (P = 0.484). CONCLUSION: LDH, ferritin and the diagnostic 123I-mIBG scans significantly predicted mCR, but only LDH predicted 2-year overall survival. Ferritin and the modified Curie scores correlated with each other. MYCN amplification neither correlated with any aspect of the 123I-mIBG scans nor significantly predicted mCR or 2-year overall survival. LDH and ferritin are therefore appropriate neuroblastoma tumour markers to be used in low- and middle-income countries with limited or no access to mIBG scans and/or MYCN amplification studies.

Impact of implementing an online interactive educational tool for future HIV "cure" research in an HIV clinic waiting room in Cape Town, South Africa.

Access to antiretroviral treatment (ART) in South Africa is suboptimal and erratic. For those on treatment, compliance remains a significant challenge. Interruptions to ART have negative implications for the individual and the epidemic. ART is therefore not a sustainable solution and there is an urgent need for a cure. As HIV cure research expands globally, the need to engage community members about cure is becoming a priority. It is vital that potential trial participants understand basic HIV cure research concepts. An online interactive educational tool was co-created with HIV stakeholders to engage and inform HIV research trial participants. The study was conducted with patients at the FAMCRU HIV clinic at Tygerberg Hospital in Cape Town, South Africa. The educational tool comprises two modules that provide information on HIV prevention, treatment and cure research. Participants completed a questionnaire before and after interacting with the programme. There was a significant increase in knowledge scores of participants demonstrated after using the tool. The interactive tool was successful in increasing participants' knowledge of HIV prevention, treatment and cure research.

Tracking progress on the health status and service delivery outcomes for neonates and children in the Metro West geographic service area of the Cape Metropole, 2010 - 2015

Background. Monitoring the health status of populations of children is one of the building blocks of the health system. The provision of an indicator dashboard with disaggregated data that are collected over time can be used to gauge the performance of the health system, guide the allocation of resources and prioritise health interventions within districts.Objectives. To determine neonatal and child mortality, morbidity and health service outcomes over a 6-year period in the Metro West geographic service area (GSA) of the Cape Town metropole.Methods. A dashboard with key indicators was developed using existing data.Results. From 2010 to 2015, there was a decrease in the perinatal mortality rate from 31.7 to 24.8 per 1 000 deliveries, and the early neonatal and neonatal mortality rates from 7.8 and 8.6 to 7.0 and 8.2 per 1 000 live births, respectively. The main obstetric causes of early neonatal deaths were antepartum haemorrhage (22 - 24%) and unexplained intrauterine death (13 - 16%); the main neonatal causes were immaturity (17 - 34%), congenital abnormalities (23 - 29%) and hypoxia (23 - 26%). Under-five mortality decreased in 2013 from 25 to 22 per 1 000 live births, with the main causes being neonatal conditions (32%), pneumonia (25%), congenital abnormalities (9%), injuries (8%) and diarrhoea (8%). Fifty percent of child deaths were out of hospital, with pneumonia and diarrhoea accounting for more than half of these. There was an improvement in health service coverage rates in 2015: immunisation <1 year old (99%); measles second dose (85%), pneumococcal third dose (100%) and rotavirus second dose (100%); maternal antiretroviral coverage (90%); HIV testing in mothers (93%); HIV DNA polymerase chain reaction testing in babies (97%); and a decrease in HIV transmission (2%). Exclusive breastfeeding coverage rates at 14 weeks, and vitamin A supplementation at 12 - 59 months, were only 30% and 44%,respectively, across the GSA.Conclusion. There was a decrease in perinatal, early neonatal, infant and under-five mortality in Metro West over the 6 years. Further reductions in under-five mortality will require focusing on interventions to reduce neonatal and out-of-hospital deaths across the service delivery platform. Home visits to at-risk mothers and infants by community health workers could prevent out-of-hospital deaths and improve exclusive breastfeeding and vitamin A coverage. This will require increasing the number of community health workers and broadening their scope of practice

Medical students' perspectives on euthanasia and physician-assisted suicide and their views on legalising these practices in South Africa.

BACKGROUND: Euthanasia/physician-assisted suicide have been a controversial and sometimes taboo topic for a long time, not only in South Africa (SA) but also internationally. A recent (SA) judicial case has seen the topic debated again. Consensus on accepting or abolishing these practices in SA has yet to be reached. All relevant role players need to be adequately engaged before policy can be informed. OBJECTIVES: To determine the views of future doctors (medical students) regarding euthanasia and physician-assisted suicide (PAS) and to ascertain their stance on its legalisation in South Africa (SA). METHODS: A paper-based, semi-quantitative descriptive study design consisting of 16 questions, using convenience sampling of third- to fifth-year medical students at Stellenbosch University, was used. RESULTS: The overall response rate was 69.3% (N=277). In total, 52.7% of participants (n=146) felt that the practices of euthanasia/PAS should be legalised in SA. Responses varied depending on patient morbidities. If a patient had terminal disease with intractable suffering, 41.9% of participants would terminate the patient's life upon request. A further 36.1% of participants stated that they would have no part in ending a patient's life, while 35.0% said that they would be comfortable with providing the patient with the correct means to end their life (PAS). The majority (80.1%) of participants indicated that they would prefer a dedicated ethics committee to decide who receives euthanasia/PAS. Many factors influenced participants' responses, but differences in opinion between and within the various religious groups were particularly evident in the responses received. CONCLUSIONS: More than half the respondents in this study were open to legalising euthanasia/PAS, substantially more than in previous studies. However, only 41.9% of respondents would consider actually performing euthanasia/PAS, for certain patients. Views of other healthcare workers as well as the public are required before policy can be informed.

Charge breeding of radioactive isotopes at the CARIBU facility with an electron beam ion source.

An Electron Beam Ion Source Charge Breeder (EBIS-CB) has been developed at Argonne National Laboratory as part of the californium rare ion breeder upgrade. For the past year, the EBIS-CB has been undergoing commissioning as part of the ATLAS accelerator complex. It has delivered both stable and radioactive beams with A/Q < 6, breeding times <30 ms, low background contamination, and charge breeding efficiencies >18% into a single charge state. The operation of this device, challenges during the commissioning phase, and future improvements will be discussed.

Local and global challenges in pediatric traumatic brain injury outcome and rehabilitation assessment.

Traumatic brain injury (TBI) is a major public health problem associated with high morbidity and mortality rates in children in both high- and low- and middle-income countries. Predicting outcome after pediatric TBI is challenging given the wide range of injury and non-injury-related factors which may have an impact. Some of these factors are relevant globally (like heterogeneity in patient and injury-related factors and research methodology) and others are more specific to local contexts (like sociodemographic and cultural factors). The assessment of rehabilitation outcomes post-TBI are similarly challenging given the various methodological limitations, disparities in access to rehabilitation, and limited awareness of deficits, which are encountered globally, as well as the lack of services in the local settings. In this article, we discuss these global and local challenges to outcome and rehabilitation assessment following pediatric TBI.

Single-centre experience of allogeneic haemopoietic stem cell transplant in paediatric patients in Cape Town, South Africa.

BACKGROUND: Allogeneic haemopoietic stem cell transplant (Allo-HSCT) is a specialised and costly intervention, associated with significant morbidity and mortality. It is used to treat a broad range of paediatric conditions. South Africa (SA) is an upper middle-income country with limitations on healthcare spending. The role of paediatric Allo-HSCT in this setting is reviewed. OBJECTIVES: To review paediatric patients who underwent Allo-HSCT at the Groote Schuur Hospital/University of Cape Town Private Academic Hospital transplant unit in Cape Town, South Africa, and received post-transplant care at Red Cross War Memorial Children's Hospital, over the period January 2006 - December 2014 in respect of indications for the transplant, donor sources, conditioning regimens, treatment-related morbidity and overall survival (OS). METHODS: A retrospective analysis of patient records was performed and a database was created in Microsoft Access. Descriptive analyses of relevant demographic, clinical and laboratory data were performed. Summary statistics of demographic and clinical parameters were derived with Excel. OS was calculated from the date of transplant to the date of an event (death) or last follow-up using the Kaplan-Meier method in Statistica. RESULTS: A total of 48 children received Allo-HSCT: 24 for haematological malignancies, 20 for non-oncological haematological conditions, 3 for immune disorders and 1 for adrenoleukodystrophy. There were 28 boys (median age 7.5 years) and 20 girls (8.5 years). There were 31 sibling matched peripheral-blood stem cell (PBSC) transplants and 1 maternal haploidentical PBSC transplant. Stem cells were mobilised from bone marrow into peripheral blood by administering granulocyte-colony stimulating factor to donors. PBSCs were harvested by apheresis. Eight patients received 10/10 HLA-matched grafts from unrelated donors. Six were PBSC grafts and 2 were bone marrow grafts. Three of the unrelated PBSC grafts were from SA donors. Eight transplants used umbilical cord blood from international registries. OS for patients with non-oncological disorders was 91.3% (median follow-up 3.9 years), while that for oncology patients was 56.8% (1.9 years). Two of the survivors developed chronic graft-versus-host disease. CONCLUSIONS: OS for non-oncological conditions was excellent, while outcomes for oncological disorders were on par with those in high-income settings. Transplantation offers many patients the opportunity for long-term survival and has been shown to be both feasible and rewarding in a less well-resourced environment servicing an economically diverse population.

Where do Children Die and what are the Causes? Under-5 Deaths in the Metro West Geographical Service Area of the Western Cape; South Africa; 2011

BACKGROUND:Accurate child mortality data are essential to plan health interventions to reduce child deaths.OBJECTIVES:To review the deaths of children aged etlt;5 years during 2011 in the Metro West geographical service area (GSA) of the Western Cape Province (WC); South Africa; from routine data sources.METHODSA retrospective study of under-5 deaths in the Metro West GSA was done using the WC Local Mortality Surveillance System (LMSS); the Child Healthcare Problem Identification Programme (Child PIP) and the Perinatal Problem Identification Programme (PPIP); and linking where possible.RESULTS:The LMSS reported 700 under-5 deaths; Child PIP 99 and PPIP 252; with an under-5 mortality rate of 18 deaths per 1 000 live births. The leading causes of death were pneumonia (25%); gastroenteritis (10%); prematurity (9%) and injuries (9%). There were 316 in-hospital deaths (45%) and 384 out-of-hospital deaths (55%). Among children aged etlt;1 year; there were significantly more pneumonia deaths out of hospital than in hospital (144 (49%) v. 16 (6%); petlt;0.001). Among children aged 1 - 4 years there were significantly more injury-related deaths out of hospital than in hospital (43 (47%) v. 4 (9%); petlt;0.001). In 56 (15%) of the cases of out-of-hospital death the child had visited a public healthcare facility within 1 week of death. Thirty-six (64%) of these children had died of pneumonia orgastroenteritis. CONCLUSIONS:Health interventions targeted at reducing under-5 deaths from pneumonia; gastroenteritis; prematurity and injuries need to be implemented across the service delivery platform in the Metro West GSA. It is important to consider all routine data sources in the evaluation of child mortality

Massage therapy improves the development of HIV-exposed infants living in a low socio-economic, peri-urban community of South Africa.

The aim of this study was to assess the effect of massage therapy on the growth and development of infants of HIV-infected mothers in a low socio-economic community in Cape Town. It was a prospective, randomised, controlled intervention trial that included massage therapy and control groups of HIV-infected mothers and their normal birth weight infants who were enrolled in the prevention of mother-to-child transmission (PMTCT) programme. Participants were recruited at the 6-week clinic visit and followed up every 2 weeks until their infants were 9 months of age. Mother-infant pairs in the massage therapy and control groups included 73 and 88 at 6 weeks and 55 and 58 at 9 months, respectively. Mothers in the intervention group were trained to massage their infants for 15 min daily. The socioeconomic status, immunity, relationship with the partner and mental pain of mothers; the infants' dietary intake, anthropometry and development (Griffiths Mental Development Scales); and haematological and iron status of mothers and infants were assessed at baseline and follow-up. Nine infants (5.3%) were HIV-infected on the HIV DNA PCR test at 6 weeks. Despite significantly higher levels of maternal mental pain, infants in the massage therapy compared to control group scored higher in all five of the Griffiths Scales of Mental Development and significantly higher in the mean quotient (p=0.002) and mean percentile (p=0.004) for the hearing and speech scale at 9 months. Based on the mean difference in scores, the massage therapy group showed greater improvement for all five scales compared to the control group. The mean difference in scores was significantly greater for the hearing and speech quotient (21.9 vs. 11.2) (p<0.03) and the general quotient percentile (19.3 vs. 7.7) (p=0.03) in the massage therapy compared to the control group. These scales remained significant when adjusting for the relationship with the partner and maternal mental pain. Both groups had lower scores in the performance scale at 9 months although this was significantly worse in the control compared to the massage therapy group when adjusting for maternal CD4 count, anaemia, relationship with the partner and mental pain. There were no significant differences in the anthropometric measurements between the two groups. In conclusion, based on the Griffiths Scales, massage therapy improved the overall development and had a significant effect on the hearing and speech and general quotient of HIV-exposed infants in this study.

First pregnancy and live birth resulting from cryopreserved embryos obtained from in vitro matured oocytes after oophorectomy in an ovarian cancer patient.

In vitro maturation (IVM) of immature oocytes retrieved from surgically resected ovaries has been proposed as a method of fertility preservation in ovarian cancer patients undergoing definitive surgery. While there had been several reports of successful derivation of mature oocytes and or embryos, there have been no reports as yet of successful pregnancies. In this case report, we present a pregnancy and live birth from a young patient, with stage IIIC ovarian cancer, who had undergone fertility sparing surgery. The immature oocytes recovered after oophorectomy were fertilized after IVM. The embryos obtained were cryopreserved and later transferred to achieve a singleton healthy pregnancy leading to a live birth.

Addiction potential of phentermine prescribed during long-term treatment of obesity.

OBJECTIVE: To investigate if phentermine treatment induces phentermine abuse, psychological dependence (addiction) or phentermine drug craving in overweight, obese and weight loss maintenance patients. To investigate whether amphetamine-like withdrawal occurs after abrupt cessation of long-term phentermine treatment. DESIGN: Clinical intervention trial with interruption of phentermine treatment in long-term patients. SUBJECTS: 269 obese, overweight or formerly obese subjects (age: 20-88 years, BMI: 21-74 kg m(-2)) treated with phentermine long-term (LTP, N=117), 1.1-21.1 years, or short-term (ATP, N=152), 4-22 days, with phentermine doses of 18.75-112.5 (LTP) and 15-93.75 (ATP) mg per day. MEASUREMENTS: Module K of the Mini International Neuropsychiatric Interview modified for phentermine (MINI-SUD), Severity of Dependence Scale (SDS), 45-item Cocaine Craving Questionnaire-NOW (CCQ-NOW) modified for phentermine (PCQ-NOW), and Amphetamine Withdrawal Questionnaire (AWQ) modified for phentermine (PWQ). RESULTS: MINI-SUD interviews were negative for phentermine abuse or psychological dependence in all LTP patients. SDS examination scores were low for all LTP and ATP patients, indicating they were not psychologically dependent upon phentermine. PCQ-NOW scores were low for all LTP and ATP patients, indicating neither short-term nor long-term phentermine treatment had induced phentermine craving. Other than an increase in hunger or eating, amphetamine-like withdrawal symptoms did not occur upon abrupt phentermine cessation as measured by sequential PWQ scores. CONCLUSIONS: Phentermine abuse or psychological dependence (addiction) does not occur in patients treated with phentermine for obesity. Phentermine treatment does not induce phentermine drug craving, a hallmark sign of addiction. Amphetamine-like withdrawal does not occur upon abrupt treatment cessation even at doses much higher than commonly recommended and after treatment durations of up to 21 years.

Hyperglycaemia in patients treated with second generation antipsychotics.

AIM: The association of second generation antipsychotic medications and hyperglycaemia has been reported for Caucasian populations but is unknown for asian patients who unfortunately are predisposed to diabetes. We report the findings from a health quality improvement project which tracked patients with schizophrenia and schizoaffective disorder newly started on second generation antipsychotics. MATERIALS AND METHODS: 266 patients were newly started on second generation antipsychotics in a 2 year period. Amongst the baseline parameters monitored was the fasting plasma glucose levels. Repeat testing was done at 4 weeks, 12 weeks and 12 months. RESULTS: 14 patients were excluded form the analysis as they had diabetes at the start of treatment with second generation antipsychotics. Hyperglycaemia was found in 88 patients (34.9%). 68 (77.3%) of these patients experienced the Hyperglycaemia at 12 weeks, 3 patients (3.4%) at 4 weeks and 17 patients (19.3%) at 12 months. Fasting plasma glucose levels were highest at 4 weeks. CONCLUSIONS: Despite the limitations of the project, the one third prevalence of hyperglycaemia amongst patients newly started on second generation antipsychotics is a cause for concern and suggests the need for further extensive follow-up and assessment of the problem.

Treatment outcome of women with a single ovary undergoing in vitro fertilisation cycles.

INTRODUCTION: Women with a single ovary present a unique problem in assisted reproductive techniques. The aim of our study was to compare the ovarian response and pregnancy rates of women with one ovary and those with two ovaries in assisted reproduction. METHODS: A total of 18 consecutive women with a single ovary (n is 22 cycles) were identified. The control group included 44 women with two ovaries and mechanical infertility, who were selected as frequency-matched samples (2:1) to meet the distribution of age at treatment and race in the single ovary group. All patients underwent controlled ovarian hyperstimulation treatment via the long down-regulation protocol using a gonadotropin-releasing hormone agonist. Standard procedures were carried out for gamete-embryo handling, and embryo transfer was performed using a soft catheter on day two in all cases. The luteal phase was supported by progesterone or Pregnyl after oocyte pick-up. RESULTS: The duration of stimulation (11.3 +/- 1.7 versus 10.1 +/- 1.4 days) and the total follicle stimulating hormone (FSH) consumption (3906.8 +/- 1860.6 mIU/ml versus 2900.0 +/- 1440.0 mIU/ml) were significantly higher, and the mean number of oocytes (10.8 +/- 4.5 versus 16.8 +/- 10.9) and metaphase II oocytes collected (9.5 +/- 4.5 versus 13.3 +/- 7.7) were significantly lower in the single ovary group (p is less than 0.05). The clinical pregnancy rates (31.8 percent versus 43.2 percent) were comparable between the two groups. CONCLUSION: Although women with a single ovary required significantly higher doses of FSH and a longer duration of stimulation, as well as produced less oocytes, their clinical pregnancy rates were comparable to those of women with two ovaries in assisted reproduction.

Validation of the Actiheart activity monitor for measurement of activity energy expenditure in children and adolescents with chronic disease.

BACKGROUND/OBJECTIVES: The purpose of this study was to develop an activity energy expenditure (AEE) prediction equation for the Actiheart activity monitor for use in children with chronic disease. SUBJECTS/METHODS: In total, 63 children, aged 8-18 years with different types of chronic disease (juvenile arthritis, hemophilia, dermatomyositis, neuromuscular disease, cystic fibrosis or congenital heart disease) participated in an activity testing session, which consisted of a resting protocol, working on the computer, sweeping, hallway walking, steps and treadmill walking at three different speeds. During all activities, actual AEE was measured with indirect calorimetry and the participants wore an Actiheart on the chest. Resting EE and resting heart rate were measured during the resting protocol and heart rate above sleep (HRaS) was calculated. RESULTS: Mixed linear modeling produced the following prediction equation: This equation results in a nonsignificant mean difference of 2.1 J/kg/min (limits of agreement: -144.2 to 148.4 J/kg/min) for the prediction of AEE from the Actiheart compared with actual AEE. CONCLUSIONS: The Actiheart is valid for the use of AEE determination when using the new prediction equation for groups of children with chronic disease. However, the prediction error limits the use of the equation in individual subjects.
