RESUMEN

Hypertensive disorders of pregnancy are common and can result in maternal and fetal morbidity and mortality. Women may have chronic hypertension, or develop hypertension during pregnancy. Management involves close maternal and fetal surveillance. If an antihypertensive drug is needed, prescribe one that is safe in pregnancy. Pre-eclampsia is a hypertensive disorder of pregnancy. Women at high risk of pre-eclampsia should start aspirin 150 mg daily at 12-16 weeks gestation and continue until 36 weeks gestation, to reduce the risk of preterm delivery. There are long-term cardiovascular and mortality risks associated with pregnancies complicated by gestational hypertension and pre-eclampsia. Ongoing cardiovascular and metabolic risk surveillance should be undertaken by the woman's general practitioner.

RESUMEN

BACKGROUND: Most assessments in health professions education consist of knowledge-based examinations as well as practical and clinical examinations. Among the most challenging aspects of clinical assessments is decision making related to borderline grades assigned by examiners. Borderline grades are commonly used by examiners when they do not have sufficient information to make clear pass/fail decisions. The interpretation of these borderline grades is rarely discussed in the literature. This study reports the application of the Objective Borderline Method (version 2, henceforth: OBM2) to a high stakes Objective Structured Clinical Examination undertaken at the end of the final year of a Medicine program in Australia. METHODS: The OBM2 uses all examination data to reclassify borderline grades as either pass or fail. Factor analysis was used to estimate the suitability of data for application of OBM2. Student's t-tests, utilising bootstrapping, were used to compare the OBM2 with 'traditional' results. Interclass correlations were used to estimate the association between the grade reclassification and all other grades in this examination. RESULTS: The correlations between scores for each station and pass/fail outcomes increased significantly after the mark reclassification, yet the reclassification did not significantly impact on students' total scores. Examiners, students and program leaders expressed high levels of satisfaction and the Faculty's Curriculum Development Committee has decided that the OBM2 will be used for all future clinical examinations. Implications of the OBM2 are discussed. CONCLUSIONS: The OBM2 provides a feasible, defensible and acceptable solution for classification of borderline grades as either pass or fail.

RESUMEN

For decades, ill-defined autosomal dominant renal diseases have been reported, which originate from tubular cells and lead to tubular atrophy and interstitial fibrosis. These diseases are clinically indistinguishable, but caused by mutations in at least four different genes: UMOD, HNF1B, REN, and, as recently described, MUC1. Affected family members show renal fibrosis in the biopsy and gradually declining renal function, with renal failure usually occurring between the third and sixth decade of life. Here we describe 10 families and define eligibility criteria to consider this type of inherited disease, as well as propose a practicable approach for diagnosis. In contrast to what the frequently used term 'Medullary Cystic Kidney Disease' implies, development of (medullary) cysts is neither an early nor a typical feature, as determined by MRI. In addition to Sanger and gene panel sequencing of the four genes, we established SNaPshot minisequencing for the predescribed cytosine duplication within a distinct repeat region of MUC1 causing a frameshift. A mutation was found in 7 of 9 families (3 in UMOD and 4 in MUC1), with one indeterminate (UMOD p.T62P). On the basis of clinical and pathological characteristics we propose the term 'Autosomal Dominant Tubulointerstitial Kidney Disease' as an improved terminology. This should enhance recognition and correct diagnosis of affected individuals, facilitate genetic counseling, and stimulate research into the underlying pathophysiology.

RESUMEN

BACKGROUND: Increased cardiovascular risk following preeclampsia is well established and there are signs of early cardiovascular aging 6 months postpartum. This study assessed whether blood pressure (BP) and other cardiovascular measures are abnormal 2 years postpartum in the same cohort to determine ongoing risk markers. METHODS: Six months and 2 years postpartum, BP was measured using sphygmomanometry, 24-hour ambulatory BP monitoring, and noninvasive central BP. Anthropometric measures, blood, and urine biochemistry were performed. Cross-sectional comparisons between preeclampsia and normotensive pregnancy (NP) groups and longitudinal comparisons within each group were made at 6 months and 2 years. RESULTS: Two years postpartum, 129 NP, and 52 preeclampsia women were studied who also had 6 months measures. At both time points, preeclampsia group had significantly higher BP (office BP 2 years, 112±12/72±8 versus 104±9/67±7 mm Hg NP; [P<0.001]; mean ambulatory BP monitoring 116±9/73±8 versus 106±8/67±6 mm Hg NP; [P<0.001]). No significant BP changes noted 6 months to 2 years within either group. Office BP thresholds of 140 mm Hg systolic and 90 mm Hg diastolic classified 2% preeclampsia and 0% NP at 2 years. American Heart Association 2017 criteria (above normal, >120/80 mm Hg) classified 25% versus 8% (P<0.002), as did our reference range threshold of 122/79 mm Hg. American Heart Association criteria classified 60% post-preeclampsia versus 16% after NP with above-normal ambulatory BP monitoring (P<0.001). Other cardiovascular risk markers more common 2 years post-preeclampsia included higher body mass index (median 26.6 versus 23.1, P=0.003) and insulin resistance. CONCLUSIONS: After preeclampsia, women have significantly higher BP 6 months and 2 years postpartum, and have higher body mass index and insulin-resistance scores, increasing their future cardiovascular risk. Regular cardiovascular risk screening should be implemented for all who have experienced preeclampsia.

RESUMEN

BACKGROUND/AIMS: Chronic kidney disease (CKD) is a major health issue worldwide. The aim of this study was to explore factors associated with CKD progression in Australian nephrology practices. METHODS: This was a retrospective study utilising an electronic medical record (EMR), Audit4 (Software for Specialists, Australia). The baseline visit was defined as the first entry into the EMR. The primary outcome was the rate of change in estimated glomerular filtration rate (eGFR). RESULTS: 1,328 patients were included with a mean eGFR at baseline of 37.4 ± 0.7 ml/min/1.73 m(2), a mean follow-up of 17.7 months and a mean annual rate of change in eGFR of -0.84 ± 0.26 ml/min/1.73 m(2). Univariate analysis demonstrated that women, smokers, and patients prescribed erythropoiesis-stimulating agents (ESA) had a significantly more rapid decline in eGFR (p = 0.007, 0.033, and 0.003, respectively). On multivariate analysis: gender, age, prescription of ESA and phosphate binders, and baseline eGFR were significantly associated with CKD progression (p = 0.003, 0.004, <0.001, 0.029, and <0.001, respectively). CONCLUSIONS: This study identifies potential factors associated with CKD progression in a population referred to nephrologists, but current data quality may result in bias. Implementation of changes in the format of data collection is required so that busy clinicians record essential information to enable this to become a more accurate and reliable research tool.

RESUMEN

Intrauterine preeclampsia exposure affects the lifelong cardiometabolic health of the child. Our study aimed to compare the growth (from birth to 6 months) of infants exposed to either a normotensive pregnancy or preeclampsia and explore the influence of being born small for gestational age (SGA). Participants were children of women participating in the Post-partum, Physiology, Psychology and Paediatric follow-up cohort study. Birth and 6-month weight and length z-scores were calculated for term and preterm (<37 weeks) babies, and change in weight z-score, rapid weight gain (≥0.67 increase in weight z-score) and conditional weight gain z-score were calculated. Compared with normotensive exposed infants (n = 298), preeclampsia exposed infants (n = 84) were more likely to be born SGA (7% versus 23%; P < 0.001), but weight gain from birth to 6 months, by any measure, did not differ between groups. Infants born SGA, irrespective of pregnancy exposure, were more likely to have rapid weight gain and had greater increases in weight z-score compared with those not born SGA. Preeclampsia exposed infants born SGA may benefit from interventions designed to prevent future cardiometabolic disease.

RESUMEN

BACKGROUND: Early identification of true renal disease (glomerular filtration rate (GFR) < 60 mL/min) results in better patient outcomes. There is now routine reporting in Australia of estimated GFR (eGFR) in all patients over age 18 who have serum creatinine measured, calculated by the Modification of Diet in Renal Disease (MDRD) formula, which was validated in an American Caucasian cohort. Significant clinical decisions and prognosis are often made on the basis of this calculation. AIM: To assess the accuracy of three estimates of GFR in an Australian population by comparing eGFR obtained by the abbreviated MDRD (aMDRD), Cockcroft-Gault corrected for body surface area (BSA) (CG) and Chronic Kidney Disease Epidemiology (CKD-Epi) formulae with a gold standard, isotopic (51) Cr-ethylenediaminetetra-acetic acid ((51) Cr-EDTA) GFR. METHODS: Patients referred with an eGFR of <60 mL/min reported by the aMDRD formula underwent isotopic measurement of GFR (over 4 h) and had eGFR calculated using CG corrected for BSA, aMDRD and CKD-Epi formulae. Data were analysed using Bland-Altman plots and regression analysis to compare methods; bias, precision and the proportion of patients correctly stratified by stage of chronic kidney disease (CKD) were also compared according to the three estimates of GFR, using (51) Cr-EDTA GFR as the gold standard. RESULTS: A total of 139 patients were recruited (female 45%), mean age 64 years and mean serum creatinine 212 µmol/L. The mean GFR (SD) (mL/min per m(2) ) for isotopic, CG, aMDRD and CKD-Epi were 47 (28), 37 (20), 32 (17) and 33 (18) (P = 0.001). CG (57%) was more likely to correctly stage CKD than aMDRD (37%) or CKD-Epi (37%), and absolute bias was significantly lower using CG than either other method (P = 0.001). CONCLUSION: In this small Australian population the CG formula corrected for BSA agreed more closely with isotopic GFR and correctly staged patients with CKD more often than the aMDRD or CKD-Epi formulae. It is important that each renal Unit considers the accuracy of estimates of GFR according to their population demographics.

RESUMEN

BACKGROUND: Preeclampsia is a major pregnancy complication associated with long-term maternal cardiometabolic disease. Research generally is focused on metabolic and pathophysiological changes during pregnancy; however, there is much less focus on the early postpartum period in subjects who suffered preeclampsia. The aim of this study was to (1) characterize energy intake and expenditure 6 months following normotensive and preeclamptic pregnancies and (2) examine associations between energy balance, body composition, insulin resistance measures (HOMA-IR), and clinical characteristics. DESIGN: A cross-sectional study 6 months following normotensive (n = 75) and preeclamptic (n = 22) pregnancies was performed. Metabolic measurements included anthropometrics measures, body composition via bioelectrical impedance analysis, 24-h energy expenditure via SenseWear Armbands, energy intake via a 3-day food diary, and serum metabolic parameters. RESULTS: Six months following preeclampsia, women had a significantly higher weight (77.3 ± 20.9 kg vs 64.5 ± 11.4 kg, P = 0.01), fat mass percentage (FM%; 40.7 ± 7.4% vs 34.9 ± 8.1%, P = 0.004), and insulin resistance (HOMA-IR 2.2 ± 1.5 vs 1.0 ± 0.7, P = 0.003), as well as reduced HDL levels (1.5 ± 0.4 mmol/L vs 1.8 ± 0.4 mmol/L, P = 0.01) compared to normotensive women. Women post-preeclampsia had lower activity-related energy expenditure (P = 0.02) but a decreased total energy intake (P = 0.02), leading to a more negative energy balance compared to their normotensive counterparts (-1942 kJ/24 h vs -480 kJ/24 h, P = 0.02). CONCLUSION: Increases in insulin resistance and FM%, reduced high-density lipoprotein, and more sedentary lifestyles characterize the postpartum period following preeclamptic compared with normotensive pregnancies. Early post-preeclampsia interventions, such as lifestyle behavior change, should be implemented and assessed to determine whether they reduce long-term cardiometabolic risk in women who experienced preeclampsia during pregnancy.

RESUMEN

INTRODUCTION: Pregnancy induces significant physiological and cardiometabolic changes, and is associated with alterations in the maternal microbiota. Increasing rates of prepregnancy obesity, metabolic abnormalities and reduced physical activity, all impact negatively on the microbiota causing an imbalance between the commensal microorganisms (termed dysbiosis), which may drive complications, such as gestational diabetes or hypertensive disorders. Considerable work is needed to define the inter-relationships between the microbiome, nutrition, physical activity and pregnancy outcomes. The role of the microbiota during pregnancy remains unclear. The aim of the study is to define microbiota signatures longitudinally throughout pregnancy and the first year post birth, and to identify key clinical and environmental variables that shape the female microbiota profile during and following pregnancy. METHODS AND ANALYSIS: The Microbiome Understanding in Maternity Study (MUMS) is an Australian prospective longitudinal cohort study involving 100 mother-infant pairs. Women are enrolled in their first trimester and followed longitudinally. Assessment occurs at <13+0, 20+0-24+6 and 32+0-36+6 weeks gestation, birth and 6 weeks, 6 months and 12 months postpartum. At each assessment, self-collected oral, vaginal and faecal samples are collected with an additional postpartum skin swab and breastmilk sample. Each infant will have oral, faecal and skin swab samples collected. Measurements include anthropometrics, body composition, blood pressure, serum hormonal and metabolic parameters and vaginal pH. Dietary intake, physical activity and psychological state will be assessed using validated self-report questionnaires, and pregnancy and infant outcomes recorded. Parametric and non-parametric hypothesis tests will be used to test the association between high-risk and low-risk pregnancies and their outcomes. ETHICS AND DISSEMINATION: The study received the following approval: South Eastern Sydney Local Health District Research Ethics Committee (17/293 (HREC/17/POWH/605). Results will be made available to the participants of MUMS, their families and the funding bodies; in the form of a summary document. Results for the greater maternity care community and other researchers will be disseminated through conferences, local, national and international presentations and peer-reviewed publications. TRIAL REGISTRATION NUMBER: ACTRN12618000471280 (prospectively registered).

RESUMEN

Background There is increased risk of hypertension, early cardiovascular disease, and premature mortality in women who have had preeclampsia. This study was undertaken to determine the upper limit of normal blood pressure (BP) 6 months postpartum and the frequency of women with prior preeclampsia who had BP above these limits, as part of the P4 (Post-Partum Physiology, Psychology and Pediatric) follow-up study. Methods and Results BP was measured by sphygmomanometer, 24-hour ambulatory BP monitoring, and non-invasive central BP at 6 months postpartum in 302 women who had normotensive pregnancy and 90 who had preeclampsia. The upper limit of normal BP (mean+2 SD) for women with normotensive pregnancy was 122/79 mm Hg for routine BP, 115/81 mm Hg for central BP, and 121/78 mm Hg for 24-hour ambulatory BP monitoring. Traditional normal values detected only 3% of women who had preeclampsia as having high BP 6 months postpartum whereas these new values detected between 13% and 19%. Women with preeclampsia had greater body mass index (27.8 versus 25.0, P<0.001) and left ventricular wall thickness but similar augmentation index. They also had lower high-density lipoprotein (59±15 versus 65±16 mg/dL, P=0.002), higher triglycerides (77±51 versus 61±35 mg/dL, P=0.005), and higher homeostatic model assessment score (2.1±1.8 versus 1.3±1.9, P<0.001). Conclusions Clinicians wishing to detect high BP in these women should be aware of the lower than usual upper limit of normal for this young cohort and where possible should use 24-hour ambulatory BP monitoring to detect these changes. This may define a subgroup of women who had preeclampsia for whom targeted BP lowering therapy would be successful.

RESUMEN

This is the Executive Summary of updated guidelines developed by the Society of Obstetric Medicine of Australia and New Zealand for the management of hypertensive diseases of pregnancy. They address a number of challenging areas including the definition of severe hypertension, the use of automated blood pressure monitors, the definition of non-proteinuric pre-eclampsia and measuring proteinuria. Controversial management issues are addressed such as the treatment of severe hypertension and other significant manifestations of pre-eclampsia, the role of expectant management in pre-eclampsia remote from term, thromboprophylaxis, appropriate fluid therapy, the role of prophylactic magnesium sulfate and anaesthetic issues for women with pre-eclampsia. The guidelines stress the need for experienced team management for women with pre-eclampsia and mandatory hospital protocols for treatment of hypertension and eclampsia. New areas addressed in the guidelines include recommended protocols for maternal and fetal investigation of women with hypertension, preconception management for women at risk of pre-eclampsia, auditing outcomes in women with hypertensive diseases of pregnancy and long-term screening for women with previous pre-eclampsia.

RESUMEN

OBJECTIVE: To determine whether outcomes differed for women with pre-eclampsia according to the presence of proteinuria and whether non-proteinuric pre-eclampsia is similar to gestational hypertension. DESIGN: From 1987 to 2005, at three hospitals in Sydney, Australia, women referred to the obstetric medicine team were recruited. Outcomes for three groups were compared: proteinuric pre-eclampsia, non-proteinuric pre-eclampsia and gestational hypertension. RESULTS: Women with proteinuric pre-eclampsia were more likely to have severe hypertension (39 versus 30%, P = 0.003), deliver preterm infants (39 versus 30%, P = 0.007) and had a higher perinatal mortality rate (25.2 versus 5.7 per 1000, P = 0.02) than those with non-proteinuric pre-eclampsia, who were more likely to have thrombocytopenia and liver disease. Women with non-proteinuric pre-eclampsia were more likely to have multiple pregnancies (3.9 versus 9.9%, P < 0.001), experience severe hypertension (8.9 versus 29.7%, P < 0.001), and deliver preterm infants (11.3 versus 30.2%, P < 0.001) who were small for gestational age (12.7 versus 20.9%, P < 0.001) than those with gestational hypertension. CONCLUSION: This study highlights differences between non-proteinuric pre-eclampsia and gestational hypertension. The subclassification of 'non-proteinuric pre-eclampsia' should be added to existing classification systems to alert clinicians to potential risks.

RESUMEN

OBJECTIVE: To identify parameters that may assist clinicians in predicting which women will develop preeclampsia (PE) after initially presenting with gestational hypertension (GH). METHODS: 118 women were recruited to the study with GH or PE. They were divided into three groups based on their diagnosis at delivery- (1) GH, (2) PE from the time of presentation, (3) those with an initial diagnosis of GH who progressed to PE. Women underwent 24 hour ambulatory blood pressure monitoring (ABPM) and had serum estrogen, progesterone, beta-HCG, leptin and adiponectin measured as possible predictors of transformation of GH to PE. RESULTS: Women who presented with GH, and progressed to PE, presented four weeks earlier (33 vs 37 weeks, p < 0.001) than those who did not progress. Women with PE, either as their initial diagnosis or after progression from GH, were delivered earlier (p < 0.001) and had more small for gestational age (SGA) babies than women with GH at delivery (p < 0.05). Those who developed PE after presenting with GH generally had higher blood pressures than those who remained as GH, significant for awake and 24 hour systolic blood pressures (p < 0.05). beta-HCG, estrogen, progesterone or leptin values were similar across the groups. Adiponectin was higher in women with established PE at presentation compared to women with GH (p = 0.02) but adiponectin failed to discriminate those women with an initial diagnosis of GH who progressed to PE. CONCLUSION: 24 hr ABPM may provide a non-invasive method of identifying this 'at risk' GH population, particularly in the case of early presentation.

RESUMEN

Background. Optimal glycaemic targets following transplantation are unknown. Understanding the impact of DM and posttransplant diabetes mellitus (PTDM) may improve patient and graft survival in transplant recipients. Aim. To determine the perioperative and one-year outcomes after renal transplantation and whether these outcomes are affected by preexisting DM, PTDM, or glycaemia during transplant admission. Method. Adult recipients of renal transplants from a single centre over 5.5 years were retrospectively reviewed. Measured outcomes during transplant admission included glycaemia and complications (infective complications, acute rejection, and return to dialysis) and, at 12 months, glycaemic control and complications (cardiovascular complication, graft failure). Results. Of 148 patients analysed, 29 (19.6%) had DM and 27 (18.2%) developed PTDM. Following transplantation, glucose levels were higher in patients with DM and PTDM. DM patients had a longer hospital stay, had more infections, and were more likely return to dialysis. PTDM patients had increased rates of acute rejection and return to dialysis. At 1 year after transplant, there were more cardiovascular complications in DM patients compared to those without DM. Conclusions. Compared to patients without DM, patients with DM or PTDM are more likely to suffer from complications perioperatively and at 12 months. Perioperative glycaemia is associated with graft function and may be a modifiable risk.

RESUMEN

BACKGROUND: Women who have had hypertension in pregnancy are at greater risk of long term cardiovascular disease (CVD). Little is known about their cardiovascular risk postpartum or the effects on the woman's mental health and the outcomes of their infants. In this project we will study the physiological and psychological health of women and the physical health and development of their infants six months, two years and five years after birth. We will establish normal blood pressure (BP) and metabolic function for women who were normotensive in pregnancy and use these to assess women who had gestational hypertension (GH) or preeclampsia (PE). DESIGN/METHODS: Women will be asked to participate if they have given birth in the preceding six months. They will be excluded if they had diabetes, hypertension, renal or other serious maternal disease prior to pregnancy or congenital anomaly in the pregnancy. We will recruit 292 women who were normotensive and their babies, 100 who had GH and 100 who had PE and their babies. They will be assessed at six months, two and five years after birth. At each assessment mothers will have their blood pressure (BP) assessed peripherally with a liquid crystal sphygmomanometer and 24h ambulatory blood pressure monitoring (ABPM), and centrally with non-invasive applanation tonometry. Additional physiological testing will include: body composition; energy balance; vascular compliance; cardiac function; liver and renal function, lipids and biochemistry; glucose and insulin; and urinalysis. Psychological status will be assessed with validated self-report questionnaires for depression, anxiety, post-traumatic stress disorder (PTSD) and mother-infant bonding. The babies will have a medical examination by a paediatrician at each assessment. Their behavioural development will be assessed with an Ages and Stages Questionnaire completed by their mother at each assessment and a developmental assessment by a child psychologist at two and five years. CONCLUSIONS: This study will re-define normal BP and other physiological parameters for young parous women thereby permitting a more sensitive assessment of post-partum BP and other cardiovascular risk markers in women who have had GH or PE. It will also determine the extent, if any, of psychological disorders in these women and developmental or other concerns in their babies.

RESUMEN

BACKGROUND: The significance of dipstick or microscopic hematuria in pregnancy is uncertain, with some studies suggesting this is associated with a greater risk for preeclampsia. We sought to determine the prevalence and clinical significance of microscopic hematuria during pregnancy. METHODS: This was a prospective case-control study in the antenatal Clinic of St George Hospital, Kogarah, Australia, a teaching hospital without tertiary referral antenatal care, with approximately 2,600 deliveries per year. One thousand pregnant women attending for routine antenatal care were invited to have a routine urinalysis performed and be referred to a nephrology clinic for further investigation if dipstick microscopic hematuria was detected on more than 1 occasion before 32 weeks' gestation. Main outcome measures were the prevalence of dipstick hematuria, prevalence of hematuria confirmed by urine microscopy, and the development of preeclampsia or gestational hypertension or delivery of a small-for-gestational-age baby. RESULTS: One hundred seventy-eight of 902 women (20%) who entered the study had dipstick hematuria on at least 2 occasions in pregnancy; 66 of 126 women (53%) who had hematuria before 32 weeks attended the nephrology clinic, where microscopic hematuria was confirmed in 40 women (61%). Renal imaging results were normal in all except 1 woman, and all women had a serum creatinine level of 0.90 mg/dL or less (< or =80 micromol/L). The development of preeclampsia or gestational hypertension or delivery of a small-for-gestational-age baby were similar in women with and without dipstick hematuria. Microscopic hematuria persisted in half (15 women) of those who attended for follow-up after 3 months postpartum. CONCLUSION: Dipstick hematuria is very common during pregnancy, but rarely signifies a disorder likely to impact on the pregnancy outcome. Postpartum follow-up is recommended to detect women who have persistent hematuria and presumed underlying mild glomerulonephritis.
