RESUMO

BACKGROUND: The Global Research on the Impact of Dermatological Diseases (GRIDD) project is developing a patient-reported measure of the impact of dermatological disease on the patient's life called Patient Reported Impact of Dermatological Diseases (PRIDD). We developed a list of 263 potential impact items through a global qualitative interview study with 68 patients. We next conducted a Delphi study to seek consensus on which of these items to prioritize for inclusion in PRIDD. This study aims to explore patterns in demographic (e.g. country) and clinical variables (e.g. disease group) across the impacts ranked as most important to European dermatology patients. METHODS: We conducted a modified, two rounds Delphi study, testing the outcomes from the previous qualitative interview study. Adults (≥18 years) living with a dermatological disease were recruited through the International Alliance of Dermatology Patient Organizations' (GlobalSkin) membership network. The survey consisted of a demographic questionnaire and 263 impact items and was available in six languages. Quantitative data were collected using ranking scales and analysed against a priori consensus criteria. Qualitative data were collected using free-text responses and a Framework Analysis was conducted. European data were obtained, and descriptive statistics, including multiple subgroup analyses, were performed. RESULTS: Out of 1154 participants, 441 Europeans representing 46 dermatological disease from 25 countries participated. The results produced a list of the top 20 impacts reported by European patients, with psychological impacts accounting for the greatest proportion. CONCLUSION: This study identified what patients consider to be the most important issues impacting their lives as a result of their dermatological disease. The data support previous evidence that patients experience profound psychological impacts and require psychological support. The findings can inform research, clinical practice and policy by indicating research questions and initiatives that are of most benefit to patients.

RESUMO

Evidence suggests that people with facial palsy may experience higher levels of distress, but the reasons for this are yet to be explored. This study aimed to explore people's illness beliefs, emotions, and behaviours in relation to their facial palsy and understand how distress is experienced by this group. Semi-structured individual interviews were conducted in the UK with adults with facial palsy. Interview questions were theoretically informed by the Common-Sense Self-Regulatory Model (CS-SRM). Thematic Analysis was conducted following a combined inductive and deductive approach. Twenty people with facial palsy participated (70% female; aged 29-84). Patient distress was accounted for by illness beliefs (symptoms, cause, control and treatment, timeline and consequences), and four additional themes (coping behaviours, social support, identity and health service provision). Experiences of anxiety, depression, and anger were widespread, and some participants experienced suicidal ideation. The burden of managing a long-term condition, altered self-perception, and social anxiety and isolation were key drivers of distress. There is a need for more integrated psychological support for patients with facial palsy. Within clinical consultations, patient's beliefs about facial palsy should be identified and systematically addressed. Service development should include appropriate referral to specialist psychological support via an established care pathway.

RESUMO

Atopic eczema (herein referred to as 'eczema') is a skin disease characterized by remitting and relapsing symptoms. The Harmonising Outcome Measures for Eczema (HOME) initiative was developed to establish a core outcome set (COS) for eczema to be measured for all future eczema trials. The core outcome set for atopic eczema clinical trials includes the domain for patient-reported eczema control, but a review of the validation of available eczema control instruments was lacking. We aimed to review the literature and systematically assess the measurement properties of validated patient-reported outcome instruments that capture eczema control. PubMed and Ovid EMBASE were searched up to 24 January 2020 for any study that reported on PROM instrument development or validation. The COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) criteria were used to assess the quality of eligible studies. We screened 12 036 titles and abstracts and 58 full texts. A total of 12 papers were included, reporting on seven PROMS. These were assessed with respect to development, reliability, construct validity and responsiveness. Two instruments, Recap of Atopic Eczema (RECAP) and the Atopic Dermatitis Control Tool (ADCT), have been developed and validated to a sufficient standard to support their recommendation as patient-reported outcome instruments for measuring control of atopic eczema as part of the HOME Core Outcome Set.

RESUMO

Purpose: Psychological distress is reasonably well documented in people with facial disfigurement; however, in patients following eye removal surgery this has not been studied adequately. We hypothesised that lower distress levels would be associated with age and more adaptive coping strategies and that women would be more likely to report higher levels of distress and, therefore, use maladaptive coping strategies.Methods: This exploratory, cross-sectional study measured distress and coping in a sample of 56 post enucleation or evisceration patients. The Hospital Anxiety and Depression Scale and the Brief COPE measured distress and coping strategies.Results: In all, 25.5% and 10.9% of the sample had high levels of anxiety and depression, respectively. Significant associations were found between levels of distress, coping strategies and demographic variables (p < .05). There were significant differences in coping strategies between those with higher and lower levels of distress (p < .05). Females reported higher levels of anxiety (U = 202.5, p < .01) and depression (U = 229, p < .05) than males. Those who experienced enucleation or evisceration aged between 20 and 39 years reported significantly higher levels of depression compared with other age groups (U = 68.5, p < .01).Conclusions: There was a relatively low level of distress across the whole sample, but we found high levels of distress in a considerable proportion (18.18%) of participants. Participants' coping strategies and levels of distress were correlated. Females and participants aged between 20 and 39 years at time of eye removal were particularly vulnerable to distress.

RESUMO

OBJECTIVE: To explore stillbirth risk across gestation in three provinces of South Africa with different antenatal care schedules. DESIGN: Retrospective audit of perinatal death data using South Africa's Perinatal Problem Identification Programme. SETTING: In 2008, the Basic Antenatal Care Programme was introduced in Limpopo and Mpumalanga provinces, reducing appointments to five visits at booking, 20, 26, 32, 38 weeks and 41 weeks if required. In the Western Cape province seven appointments remained at booking, 20, 26, 32, 34, 36, 38 and 41 weeks if required. POPULATION: All audited stillbirths (n = 4211) between October 2013 to August 2015 in Limpopo, Mpumalanga and Western Cape. METHODS: Stillbirth risk (26-42 weeks of gestation, >1000 g) across gestation was calculated using Yudkin's method. Stillbirth risk was compared between provinces and relative risks were calculated between Limpopo/ Mpumalanga and Western Cape. MAIN OUTCOME MEASURES: Stillbirth risk across gestation. RESULTS: Stillbirth risk peaked at 38 weeks of gestation in Limpopo (relative risk [RR] 3.11, 95% CI 2.40-4.03, P < 0.001)and Mpumalanga (RR 3.09, 95% CI 2.37-4.02, P < 0.001) compared with Western Cape, where no peak was observed. Stillbirth risk at 38 weeks gestation in Limpopo and Mpumalanga were statistically greater than both the 37 and 39 weeks gestation within provinces (P < 0.001). As expected, a peak at 41 weeks of gestation was observed in all provinces. CONCLUSIONS: The increased period of stillbirth risk occurs after a 6-week absence of antenatal care. This calls for a refocus on the impact of reduced antenatal care visits during the third trimester. TWEETABLE ABSTRACT: Reduced antenatal care in the third trimester may increase stillbirth risk.

RESUMO

BACKGROUND: Stillbirth is a global health problem. The World Health Organization (WHO) application of the International Classification of Diseases for perinatal mortality (ICD-PM) aims to improve data on stillbirth to enable prevention. OBJECTIVES: To identify globally reported causes of stillbirth, classification systems, and alignment with the ICD-PM. SEARCH STRATEGY: We searched CINAHL, EMBASE, Medline, Global Health, and Pubmed from 2009 to 2016. SELECTION CRITERIA: Reports of stillbirth causes in unselective cohorts. DATA COLLECTION AND ANALYSIS: Pooled estimates of causes were derived for country representative reports. Systems and causes were assessed for alignment with the ICD-PM. Data are presented by income setting (low, middle, and high income countries; LIC, MIC, HIC). MAIN RESULTS: Eighty-five reports from 50 countries (489 089 stillbirths) were included. The most frequent categories were Unexplained, Antepartum haemorrhage, and Other (all settings); Infection and Hypoxic peripartum (LIC), and Placental (MIC, HIC). Overall report quality was low. Only one classification system fully aligned with ICD-PM. All stillbirth causes mapped to ICD-PM. In a subset from HIC, mapping obscured major causes. CONCLUSIONS: There is a paucity of quality information on causes of stillbirth globally. Improving investigation of stillbirths and standardisation of audit and classification is urgently needed and should be achievable in all well-resourced settings. Implementation of the WHO Perinatal Mortality Audit and Review guide is needed, particularly across high burden settings. FUNDING: HR, SH, SHL, and AW were supported by an NHMRC-CRE grant (APP1116640). VF was funded by an NHMRC-CDF (APP1123611). TWEETABLE ABSTRACT: Urgent need to improve data on causes of stillbirths across all settings to meet global targets. PLAIN LANGUAGE SUMMARY: Background and methods Nearly three million babies are stillborn every year. These deaths have deep and long-lasting effects on parents, healthcare providers, and the society. One of the major challenges to preventing stillbirths is the lack of information about why they happen. In this study, we collected reports on the causes of stillbirth from high-, middle-, and low-income countries to: (1) Understand the causes of stillbirth, and (2) Understand how to improve reporting of stillbirths. Findings We found 85 reports from 50 different countries. The information available from the reports was inconsistent and often of poor quality, so it was hard to get a clear picture about what are the causes of stillbirth across the world. Many different definitions of stillbirth were used. There was also wide variation in what investigations of the mother and baby were undertaken to identify the cause of stillbirth. Stillbirths in all income settings (low-, middle-, and high-income countries) were most frequently reported as Unexplained, Other, and Haemorrhage (bleeding). Unexplained and Other are not helpful in understanding why a baby was stillborn. In low-income countries, stillbirths were often attributed to Infection and Complications during labour and birth. In middle- and high-income countries, stillbirths were often reported as Placental complications. Limitations We may have missed some reports as searches were carried out in English only. The available reports were of poor quality. Implications Many countries, particularly those where the majority of stillbirths occur, do not report any information about these deaths. Where there are reports, the quality is often poor. It is important to improve the investigation and reporting of stillbirth using a standardised system so that policy makers and healthcare workers can develop effective stillbirth prevention programs. All stillbirths should be investigated and reported in line with the World Health Organization standards.

RESUMO

OBJECTIVE: Most severe pregnancy complications are characterized by profound hemodynamic disturbances, thus there is a need for validated hemodynamic monitoring systems for pregnant women. Pulmonary artery catheterization (PAC) using thermodilution is the clinical gold standard for the measurement of cardiac output (CO), however this reference method is rarely performed owing to its invasive nature. Transthoracic echocardiography (TTE) allows non-invasive determination of CO. We aimed to validate TTE against PAC for the determination of CO in severely ill pregnant women. METHODS: This study consisted of a meta-analysis combining data from a prospective study and a systematic review. The prospective arm was conducted in Pretoria, South Africa, in 2003. Women with severe pregnancy complications requiring invasive monitoring with PAC according to contemporary guidelines were included. TTE was performed within 15 min of PAC and the investigator was blinded to the PAC measurements. Comparative measurements were extracted from similar studies retrieved from a systematic review of the literature and added to a database. Simultaneous CO measurements by TTE and PAC were compared. Agreement between methods was assessed using Bland-Altman statistics and intraclass correlation coefficients (ICC). RESULTS: Thirty-four comparative measurements were included in the meta-analysis. Mean CO values obtained by PAC and TTE were 7.39 L/min and 7.18 L/min, respectively. The bias was 0.21 L/min with lower and upper limits of agreement of -1.18 L/min and 1.60 L/min, percentage error was 19.1%, and ICC between the two methods was 0.94. CONCLUSIONS: CO measurements by TTE show excellent agreement with those obtained by PAC in pregnant women. Given its non-invasive nature and availability, TTE could be considered as a reference for the validation of other CO techniques in pregnant women. Copyright © 2016 ISUOG.

RESUMEN OBJETIVO: Las complicaciones del embarazo más graves se caracterizan por trastornos hemodinámicos serios, debido a los cuales existe la necesidad de sistemas validados de monitorización hemodinámica para mujeres embarazadas. Aunque la cateterización de la arteria pulmonar (CAP) mediante termodilución es el patrón de referencia clínico para la medición del gasto cardíaco (GC), este método se usa con poca frecuencia debido a su naturaleza invasiva. La ecocardiografía transtorácica (ETT) permite la determinación no invasiva del GC. El objetivo de este estudio fue validar la ETT frente al CAP para determinar el GC en mujeres embarazadas gravemente enfermas. MÉTODOS: Este estudio consistió en un metaanálisis que combinó datos de un estudio prospectivo y una revisión sistemática. El estudio prospectivo se llevó a cabo en Pretoria (Sudáfrica) en 2003. Se incluyeron mujeres con complicaciones graves en el embarazo que requerían una monitorización invasiva mediante CAP según las directrices de ese momento. Se realizó una ETT en un plazo de 15 minutos de haber realizado el CAP y el investigador no tuvo acceso a las mediciones del CAP. Las mediciones comparativas se extrajeron de estudios similares obtenidos a partir de una revisión sistemática de la literatura y se añadieron a una base de datos. Se compararon las mediciones simultáneas del GC mediante ETT y CAP. La concordancia entre métodos se evaluó a través del método estadístico de Bland-Altman y de coeficientes de correlación intraclase (CCI). RESULTADOS: Se incluyeron treinta y cuatro mediciones comparativas en el metaanálisis. Los valores medios del GC obtenidos mediante CAP y ETT fueron de 7,39 l/min y 7.18 l/min, respectivamente. El sesgo fue de 0,21 l/min, siendo los límites inferior y superior de la concordancia de -1,18 l/min y 1.60 l/min; el error porcentual fue del 19,1%, y el CCI entre ambos métodos fue de 0,94. CONCLUSIONES: Las mediciones del GC en mujeres embarazadas mediante ETT muestran una excelente concordancia con las obtenidas mediante CAP. Dada su naturaleza no invasiva y su disponibilidad, la ETT podría considerarse como referencia para la validación de otras técnicas relacionadas con el GC en mujeres embarazadas. : ,。(pulmonary artery catheterization,PAC)(cardiac output,CO),,。(transthoracic echocardiography,TTE)CO。PACTTECO。 : meta。2003。PAC。PAC 15 minTTE,PAC。,。TTEPACCO。Bland-Altman(intraclass correlation coefficients,ICC)。 : meta34。PACTTECO7.39 L/min7.18 L/min。-1.18 L/min、1.60 L/min0.21 L/min,19.1%,ICC0.94。 : TTECOPACCO。,TTECO。.

RESUMO

Anaerobic digestion enables the water industry to treat wastewater as a resource for generating energy and recovering valuable by-products. The complexity of the anaerobic digestion process has motivated the development of complex models. However, this complexity makes it intractable to pin-point stability and emergent behaviour. Here, the widely used Anaerobic Digestion Model No. 1 (ADM1) has been reduced to its very backbone, a syntrophic two-tiered microbial 'food chain' and a slightly more complex three-tiered microbial 'food web', with their stability analysed as a function of the inflowing substrate concentration and dilution rate. Parameterised for phenol and chlorophenol degradation, steady-states were always stable and non-oscillatory. Low input concentrations of chlorophenol were sufficient to maintain chlorophenol- and phenol-degrading populations but resulted in poor conversion and a hydrogen flux that was too low to sustain hydrogenotrophic methanogens. The addition of hydrogen and phenol boosted the populations of all three organisms, resulting in the counterintuitive phenomena that (i) the phenol degraders were stimulated by adding hydrogen, even though hydrogen inhibits phenol degradation, and (ii) the dechlorinators indirectly benefitted from measures that stimulated their hydrogenotrophic competitors; both phenomena hint at emergent behaviour.

RESUMO

OBJECTIVE: To apply the World Health Organization (WHO) Application of the International Classification of Diseases, tenth revision (ICD-10) to deaths during the perinatal period: ICD-Perinatal Mortality (ICD-PM) to existing perinatal death databases. DESIGN: Retrospective application of ICD-PM. SETTING: South Africa, UK. POPULATION: Perinatal death databases. METHODS: Deaths were grouped according to timing of death and then by the ICD-PM cause of death. The main maternal condition at the time of perinatal death was assigned to each case. MAIN OUTCOME MEASURES: Causes of perinatal mortality, associated maternal conditions. RESULTS: In South Africa 344/689 (50%) deaths occurred antepartum, 11% (n = 74) intrapartum and 39% (n = 271) in the early neonatal period. In the UK 4377/9067 (48.3%) deaths occurred antepartum, with 457 (5%) intrapartum and 4233 (46.7%) in the neonatal period. Antepartum deaths were due to unspecified causes (59%), chromosomal abnormalities (21%) or problems related to fetal growth (14%). Intrapartum deaths followed acute intrapartum events (69%); neonatal deaths followed consequences of low birthweight/ prematurity (31%), chromosomal abnormalities (26%), or unspecified causes in healthy mothers (25%). Mothers were often healthy; 53%, 38% and 45% in the antepartum, intrapartum and neonatal death groups, respectively. Where there was a maternal condition, it was most often maternal medical conditions, and complications of placenta, cord and membranes. CONCLUSIONS: The ICD-PM can be a globally applicable perinatal death classification system that emphasises the need for a focus on the mother-baby dyad as we move beyond 2015. TWEETABLE ABSTRACT: ICD-PM is a global system that classifies perinatal deaths and links them to maternal conditions.

RESUMO

OBJECTIVE: We explore preterm-related neonatal deaths using the WHO application of the International Classification of Disease (ICD-10) to deaths during the perinatal period: ICD-PM as an informative case study, where ICD-PM can improve data use to guide clinical practice and programmatic decision-making. DESIGN: Retrospective application of ICD-PM. SETTING: South Africa, and the UK. POPULATION: Perinatal death databases. METHODS: Descriptive analysis of neonatal deaths and maternal conditions present. MAIN OUTCOME MEASURES: Causes of preterm neonatal mortality and associated maternal conditions. RESULTS: We included 98 term and 173 preterm early neonatal deaths from South Africa, and 956 term and 3248 preterm neonatal deaths from the UK. In the South African data set, the main causes of death were respiratory/cardiovascular disorders (34.7%), low birthweight/prematurity (29.2%), and disorders of cerebral status (25.5%). Amongst preterm deaths, low birthweight/prematurity (43.9%) and respiratory/cardiovascular disorders (32.4%) were the leading causes. In the data set from the UK, the leading causes of death were low birthweight/prematurity (31.6%), congenital abnormalities (27.4%), and deaths of unspecified cause (26.1%). In the preterm deaths, the leading causes were low birthweight/prematurity (40.9%) and deaths of unspecified cause (29.6%). In South Africa, 61% of preterm deaths resulted from the maternal condition of preterm spontaneous labour. Among the preterm deaths in the data set from the UK, no maternal condition was present in 36%, followed by complications of placenta, cord, and membranes (23%), and other complications of labour and delivery (22%). CONCLUSIONS: ICD-PM can be used to appraise the maternal and newborn conditions contributing to preterm deaths, and can inform practice. TWEETABLE ABSTRACT: ICD-PM can be used to appraise maternal and newborn contributors to preterm deaths to improve quality of care.

RESUMO

OBJECTIVE: The WHO application of the tenth edition of the International Classification of Diseases (ICD-10) to deaths during the perinatal period (ICD Perinatal Mortality, ICD-PM) captures the essential characteristics of the mother-baby dyad that contribute to perinatal deaths. We compare the capture of maternal conditions in the existing ICD-PM with the maternal codes from the WHO application of ICD-10 to deaths during pregnancy, childbirth, and the puerperium (ICD Maternal Mortality, ICD-MM) to explore potential benefits in the quality of data received. DESIGN: Retrospective application of ICD-PM. SETTING: South Africa and the UK. POPULATION: Perinatal death databases. METHODS: The maternal conditions were classified using the ICD-PM groupings for maternal condition in perinatal death, and then mapped to the ICD-MM groupings of maternal conditions. MAIN OUTCOME MEASURES: Main maternal conditions in perinatal deaths. RESULTS: We reviewed 9661 perinatal deaths. The largest group (4766 cases, 49.3%) in both classifications captures deaths where there was no contributing maternal condition. Each of the other ICD-PM groups map to between three and six ICD-MM groups. If the cases in each ICD-PM group are re-coded using ICD-MM, each group becomes multiple, more specific groups. For example, the 712 cases in group M4 in ICD-PM become 14 different and more specific main disease categories when the ICD-MM is applied instead. CONCLUSIONS: As we move towards ICD-11, the use of the more specific, applicable, and relevant codes outlined in ICD-MM for both maternal deaths and the maternal condition at the time of a perinatal death would be preferable, and would provide important additional information about perinatal deaths. TWEETABLE ABSTRACT: Improving the capture of maternal conditions in perinatal deaths provides important actionable information.

RESUMO

OBJECTIVES: The purpose of this study was to evaluate markers of iron status and inflammation/oxidative stress in maternal and cord blood (CB) of HIV-infected and HIV-uninfected women as potential mechanisms for poor outcomes among HIV-exposed, uninfected (HEU) infants. METHODS: Maternal venous blood and CB specimens were obtained from 87 pregnant women (45 HIV-infected and 42 HIV-uninfected) enrolled at Kalafong Hospital, Pretoria, South Africa. Iron status [serum iron, ferritin and transferrin concentrations, transferrin saturation, soluble transferrin receptor (sTfR) concentration and the sTfR/log ferritin (sTfR/F) index], antenatal exposure to inflammation (CB C-reactive protein and interleukin-6 concentrations and haptoglobin switch-on status) and oxidative stress [total radical trapping ability of CB plasma (TRAP) and chronic oxidative stress (soluble receptor of advanced glycation end-products (sRAGE) concentration] were assessed in laboratory studies. RESULTS: There were no differences between the HIV-infected and HIV-uninfected groups in maternal haematological and iron indices, except that HIV-infected mothers had decreased white blood cell counts (P = 0.048) and increased serum ferritin concentrations (P = 0.032). Ferritin levels were significantly higher in CB than in maternal blood (P < 0.001) in both groups and further elevated in the CB of HEU infants (P = 0.044). There was also an inverse relationship between CB sTfR/F index and sRAGE (r = -0.43; P = 0.003) in the HIV-infected but not in the HIV-uninfected group. CONCLUSIONS: Our study showed for the first time that ferritin was significantly elevated in CB of HEU infants. The inverse relationship between sTfR/F index and sRAGE in CB suggests that chronic oxidative stress or RAGE axis activation in HIV-infected mothers may play a role in modulating ferritin levels.

RESUMO

Understanding the causes of and factors contributing to maternal deaths is critically important for development of interventions that reduce the global burden of maternal mortality and morbidity. The International Classification of Diseases-Maternal Mortality (ICD-MM) classification of cause of death during pregnancy, childbirth and the puerperium was applied to data obtained from maternal death reviews (MDR) for 4558 maternal deaths from five countries in sub-Saharan Africa. None of the data sets identified type of maternal death. Information obtained via MDR is generally sufficient to agree on classification of cause of death to the levels of type and group. The terms 'underlying cause of death' and 'contributing conditions' were used differently in different settings and a specific underlying cause of death was frequently not recorded. Application of ICD-MM resulted in the reclassification of 3.1% (9/285) of cases to the group 'unanticipated complications of management', previously recorded as obstetric haemorrhage or unknown. An increased number of cases were assigned to the groups pregnancy-related infection (5.6-10.2%) and pregnancies with abortive outcome (3.4-4.9%) when a clear distinction was made between women who died 'with' HIV/AIDS of obstetric causes (direct maternal death) and AIDS-related indirect maternal deaths (group 'non-obstetric complications'). Similarly, anaemia and obstructed labour were more frequently identified as contributing factors than underlying cause of death. It would be helpful if MDR forms could have explicitly stated variables called: type, group and underlying cause of death as well as a dedicated section to the most frequently occurring contributing conditions recognised in that setting.

RESUMO

The Confidential Enquiry into Maternal Deaths (CEMD) in South Africa has been operational for 15 years. This case study describes the process of notification and independent assessment of maternal deaths, predominantly in facilities. In the earlier years of the Enquiry, institutional maternal mortality ratio increased and was 176.2 per 100 000 live births in the 2008-10 triennium; thereafter it decreased to 146.7 in the 2011/12 period. The slow progress was due to the significant contribution of HIV/AIDs to maternal mortality and challenges in implementing the recommendations that were devised from the findings of the Enquiry. Nevertheless, the CEMD process has been maintained and strengthened so it is currently able to perform routine maternal death surveillance at both national and district levels, identify deficiencies within the health system, generate reports and also provide early warning about alarming trends such as the increasing numbers of deaths due to caesarean-section-associated haemorrhage.

RESUMO

The Perinatal Problem Identification Programme (PPIP) was designed and developed in South Africa as a facility audit tool for perinatal deaths. It has been used by only a few hospitals since the late 1990s, but since the country's commitment to achieve Millennium Development Goal 4-the use of PPIP is now mandatory for all facilities delivering pregnant mothers and caring for newborns. To date 588 sites, representing 73% of the deliveries captured by the District Health Information System for South Africa, provide data to the national database at the Medical Research Council Unit for Maternal and Infant Health Care Strategies in Pretoria.

RESUMO

INTRODUCTION: Delivering 24 h healthcare requires rotational shift work from doctors and the medical imaging team, while contributing to safe and timely care of patients. Additional service pressure and staff shortfall leads to workload pressures, adjusted shift patterns and risk of burnout. Evidence should be sought to the effects of this work on staff. METHODS: This systematic review followed PRISMA reporting guidelines, using a convergent mixed methods approach according to Guidance from Joanna Briggs International. Quantitative trends and results were qualified in order to thematically analyse in conjunction with qualitative data and discussed together in context. Following initial searching, returned articles were screened by title and abstract. A team of 3 reviewers undertook blinded critical appraisal of those suitable, with quality assurance from a 4th team member. Papers passing a threshold of 75% on JBI appraisal tools were accepted for synthesis. Data extraction of appropriate articles retrieved was undertaken in parallel. RESULTS: Following screening and critical appraisal, 13 studies were returned focusing exclusively on Non Consultant Doctors. No studies investigated diagnostic radiographers. 85% (n = 11) reported negative association between shift work and the three themes of sleep/fatigue, burnout and wellbeing: including after the introduction of shift pattern control or adjusted shift patterns. The remainder showed no change, or any improvement nullified by countermeasures to maintain service delivery. CONCLUSION: Current working practices and shift plans in the target population showed detrimental effects on the participants - this can be suggested that Diagnostic Radiographers may suffer fatigue, burnout and poor mental health from stretched shift working patterns. IMPLICATIONS FOR PRACTICE: Further study into the effects of shift work on Diagnostic Radiographers and other allied health professionals is indicated - relating to the above themes in the context of errors and patient safety. Additional research into Non Consultant Doctors, shift work effects and the context of wider service delivery required; with suitable interventions and education to maximise understanding of legal working practices, monitoring and self-management of symptoms.

RESUMO

Reliable data from South Africa emanating from WHO recommendations for the Safe Motherhood programme underscores HIV/AIDS as the most common cause of maternal deaths. The strengthening of HIV services for pregnant women especially in countries with a high burden of HIV infection will reduce HIV-related and un-related maternal mortality rates. High-quality and complete data on maternal deaths is a critical foundation for reliably monitoring temporal trends in maternal deaths, and causes thereof, but needs substantial strengthening in many resource-constrained settings. HIV/AIDS is an increasing contributor to direct and indirect causes of maternal deaths in sub-Saharan Africa. A review of published data on maternal deaths and its association with HIV shows that reliable data come from the Confidential Enquiries into Maternal Deaths from South Africa, population-based surveys in sentinel populations, and facility-based data. Despite an increase in knowledge of the HIV status of pregnant women and the initiation of antiretroviral treatment, reversals in trends towards increased maternal deaths are not being observed. The strengthening of HIV services provides an opportunity to alter HIV epidemic trajectories and reduce maternal deaths.
