Associations of preconception Body Mass Index in women with PCOS and BMI and blood pressure of their offspring.

Women with polycystic ovary syndrome (PCOS) have unfavorable metabolic profiles. Their offspring may be affected by such risks. The objective of the current study was to disclose associations between preconception health of these women and health of their offspring. 74 women diagnosed with PCOS according to the Rotterdam criteria were screened systematically before conception. Cardiovascular health of their offspring was assessed at 2.5-4 (n = 42) or at 6-8 years of age (n = 32). Multivariate linear regression analysis was performed with adjustments for potential confounders. In the primary analyses the association between preconception Body Mass index (BMI) and offspring BMI was evaluated. Secondly associations between preconception blood pressure, androgens, insulin-resistance (HOMA-IR), and LDL-cholesterol in women with PCOS and BMI and blood pressure of offspring were assessed. Results show that preconception BMI of women with PCOS was positively associated with sex- and age-adjusted BMI of their offspring at 6-8 years of age (ß = 0.55 (95% CI: 0.12 to 0.97), p = .012). No other significant associations were found. In conclusion, our data suggest that preconception BMI in PCOS is significantly associated with offspring BMI at 6-8 year of age. If this suggestion could be confirmed this may provide an opportunity for improving the future health of these children.

Implications of the 2014 Androgen Excess and Polycystic Ovary Syndrome Society guidelines on polycystic ovarian morphology for polycystic ovary syndrome diagnosis.

The Androgen Excess and Polycystic Ovary Syndrome Society (AEPCOS) has recommended an updated threshold for polycystic ovarian morphology (PCOM) of 25 follicles or more, 10 ml or more of ovarian volume, or both. We describe the effect of these guidelines on reproductive and metabolic characteristics in 404 women. These women were separated into four groups: group A: hyperandrogenism and oligo-amenorrhoea (n = 157); group B: hyperandrogenism or oligo-amenorrhoea and PCOM meeting AEPCOS 2014 criteria (n = 125); group C: hyperandrogenism or oligo-amenorrhoea and PCOM meeting Rotterdam 2003 but not AEPCOS 2014 criteria (n = 72); and group D: non-PCOS not meeting either criteria (n = 50). Groups B, C and D did not differ across any metabolic markers. The AEPCOS 2014 guidelines may have limited utility in distinguishing metabolic risk factors and result in the exclusion of a large group of oligo-anovulatory women.

Are women with polycystic ovary syndrome at increased cardiovascular disease risk later in life?

To date, the world's leading cause of death amongst women is cardiovascular disease. Polycystic ovary syndrome (PCOS) is associated with an unfavorable cardiometabolic profile in early life. Apart from dyslipidemia, obesity and onset of type 2 diabetes mellitus, androgens are thought to influence cardiovascular health. The question rises whether women with PCOS are truly at risk for cardiovascular disease in later life. In this review paper, we aim to reflect on this assumed relation based on studies in different stages of life in women with PCOS. Cardiovascular risk factors (type 2 diabetes mellitus, obesity and metabolic syndrome), surrogate outcomes (flow-mediated dilation, carotid intima-media thickness and coronary artery calcium) and clinical long-term outcomes (cardiovascular disease and mortality) will be summarized. Data on cardiovascular disease and mortality in peri- and postmenopausal women with PCOS appear to be controversial. Whether androgens have a protective or unfavorable influence on the manifestation of cardiovascular disease remains uncertain. The need for large, prospective, well-phenotyped cohort studies of women with PCOS is high. Only then will we be able to answer this research question.

A critical review of the potential impacts of marine seismic surveys on fish & invertebrates.

Marine seismic surveys produce high intensity, low-frequency impulsive sounds at regular intervals, with most sound produced between 10 and 300Hz. Offshore seismic surveys have long been considered to be disruptive to fisheries, but there are few ecological studies that target commercially important species, particularly invertebrates. This review aims to summarise scientific studies investigating the impacts of low-frequency sound on marine fish and invertebrates, as well as to critically evaluate how such studies may apply to field populations exposed to seismic operations. We focus on marine seismic surveys due to their associated unique sound properties (i.e. acute, low-frequency, mobile source locations), as well as fish and invertebrates due to the commercial value of many species in these groups. The main challenges of seismic impact research are the translation of laboratory results to field populations over a range of sound exposure scenarios and the lack of sound exposure standardisation which hinders the identification of response thresholds. An integrated multidisciplinary approach to manipulative and in situ studies is the most effective way to establish impact thresholds in the context of realistic exposure levels, but if that is not practical the limitations of each approach must be carefully considered.

The impact of age and chronic kidney disease on secondary prevention post-primary percutaneous coronary intervention.

OBJECTIVE: Historical data suggest elderly patients and those with chronic kidney disease (CKD) receive suboptimal secondary prevention following myocardial infarction (MI). We evaluated the impact of age and CKD on secondary prevention following primary percutaneous coronary intervention (PPCI) in a contemporary unselected cohort. DESIGN: We studied 1169 consecutive patients from five UK centres receiving PPCI for ST elevation MI, with use of evidence-based secondary prevention at discharge assessed by age (<60, 60-75 and >75 years) and estimated glomerular filtration rate (eGFR). Follow-up prescribing practice was assessed in 567 patients. RESULTS: One-fifth of patients receiving PPCI were >75 years. This group received fewer secondary prevention drugs at discharge compared to younger patients (P < 0.01 for ß-blockers, angiotensin-converting enzyme (ACE) inhibitors/angiotensin receptor blockers (ARB) and statins). By 6 weeks post-PPCI, there was a small drop-off in evidence-based therapy; ß-blocker and statin use in those >75 years fell from 90% to 86% and 96% to 93%, respectively. CKD (eGFR<60 ml/min/1.73 m(2)) was seen in 17.6%. Declining renal function was associated with age, female sex and lower use of ACE inhibitor/ARB. At discharge 83.5% of patients with eGFR<60 ml/min/1.73 m(2) were receiving ACE inhibitors/ARB, dropping to 77.5% at 6 weeks (compared with 95% and 92%, respectively, in patients with eGFR >60 ml/min/1.73 m(2)). CONCLUSION: The uptake of secondary prevention medication is high following PPCI in the UK, even in the elderly and in those with renal dysfunction. A focus on strategies to improve up-titration and continuation of drugs following discharge is required.

The haemodynamic response to pre-hospital RSI in injured patients.

BACKGROUND: Laryngoscopy and tracheal intubation provoke a marked sympathetic response, potentially harmful in patients with cerebral or cardiovascular pathology or haemorrhage. Standard pre-hospital rapid sequence induction of anaesthesia (RSI) does not incorporate agents that attenuate this response. It is not known if a clinically significant response occurs following pre-hospital RSI or what proportion of injured patients requiring the intervention are potentially at risk in this setting. METHODS: We performed a retrospective analysis of 115 consecutive pre-hospital RSI's performed on trauma patients in a physician-led Helicopter Emergency Medical Service. Primary outcome was the acute haemodynamic response to the procedure. A clinically significant response was defined as a greater than 20% change from baseline recordings during laryngoscopy and intubation. RESULTS: Laryngoscopy and intubation provoked a hypertensive response in 79% of cases. Almost one-in-ten patients experienced a greater than 100% increase in mean arterial pressure (MAP) and/or systolic blood pressure (SBP). The mean (95% CI) increase in SBP was 41(31-51) mmHg and MAP was 30(23-37) mmHg. Conditions leaving the patient vulnerable to secondary injury from a hypertensive response were common. CONCLUSIONS: Laryngoscopy and tracheal intubation, following a standard pre-hospital RSI, commonly induced a clinically significant hypertensive response in the trauma patients studied. We believe that, although this technique is effective in securing the pre-hospital trauma airway, it is poor at attenuating adverse physiological effects that may be detrimental in this patient group.

An evaluation of the range and availability of intensive smoking cessation services in Ireland.

BACKGROUND: A review of smoking cessation (SC) services in Ireland is a necessary step in improving service planning and provision. AIMS: To assess the range and availability of intensive SC services in Ireland in 2006. METHODS: A survey of SC service providers in Ireland was conducted. Descriptive analysis and simple linear regression analysis was used. RESULTS: Response rate was 86.3% (63/73). All service providers surveyed are employing evidence-based interventions; the most common form of support is individual counselling with initial sessions averaging 40 min and weekly review sessions 20 min in duration. Reaching the recommended target of treating 5.0% of smokers does not seem feasible given the current distribution of resources and there appears to be regional differences in resource allocation. CONCLUSIONS: While intensive SC services are available in all four Health Service Executive Areas, it would appear that there is little uniformity or consistency countrywide in the scope and structure of these services.

The surgical management of 73 vascular malformations and preoperative predictive factors of major haemorrhage--a single centre experience.

OBJECTIVES: In our series of patients with congenital vascular malformations (CVMs) we investigate the preoperative factors for predicting major haemorrhage at surgery and propose an algorithm for their surgical management. DESIGN: This is a partly prospective case series of patients with severe symptoms/complications due to CVMs. MATERIALS AND METHODS: Data were collected on 73 consecutive procedures in 41 patients with CVMs from 1992 to 2006 at a large university hospital and the association of following factors with blood loss during the procedure were investigated: type of procedure, possibility of proximal tourniquet use, lesion flow characteristics, previous history of major haemorrhage with CVM surgery, platelet counts and length of hospital stay. RESULTS: Significantly higher blood loss was associated with debulking surgery (p=0.006) and with previous history of major haemorrhage during CVM surgery, (p=0.041). Blood loss was higher in lesions where proximal tourniquet application was not possible (p=0.093). High-flow lesions were not strongly associated with major blood loss (p=0.288). Major blood loss (>2l) occurred in 16 (20.8%) procedures performed on 11 (26.2%) patients, but this did not prolong hospital stay. CONCLUSION: Surgery can potentially improve morbidity/mortality in patients with life/limb-threatening complications or severe symptoms due to CVMs, providing they are managed in multidisciplinary specialised centres.

Developing policy in the provision of parenting programmes: integrating a review of reviews with the perspectives of both parents and professionals.

BACKGROUND: Parenting programmes are a key component of the delivery of children's services, but evidence-based policy has often proved difficult to implement. METHODS: The present review addressed this issue by integrating a review of systematic reviews of parenting programmes and a series of focus groups with parents and professionals involved in parenting across three agencies in a regional area (health, education and social work). The review summarizes parenting interventions targeting infant mental health, emotional and behavioural difficulties, autism spectrum disorder and attention deficit hyperactivity disorder, abuse/neglect, alcohol/substance abuse and 'vulnerable' parents. The focus groups discussed topics such as the range of parenting services across the three agencies, accessibility, gaps in the service and future directions. RESULTS AND CONCLUSIONS: Twenty systematic reviews were summarized. These reviews demonstrated that there is a wide range of parenting programmes available that have the potential to benefit families who are affected by problems ranging from emotional and behavioural difficulties to adolescent substance abuse. However, the findings of the focus groups reveal that the success of these programmes will depend in part on how they can be tailored to meet the social context of the families targeted. These integrated findings are discussed in terms of their implications for policy and practice.

Circulating biomarkers of angiogenesis as indicators of left ventricular systolic dysfunction amongst patients with coronary artery disease.

BACKGROUND: Patients with coronary artery disease (CAD) and left ventricular systolic dysfunction (LVSD) are often asymptomatic. Angiogenesis is implicated in the physiology of vascular repair and cardiac remodelling, and is one of many pathophysiological processes implicated in heart failure. We hypothesized that plasma indices associated with angiogenesis [angiogenin, vascular endothelial growth factor (VEGF), and angiopoietin (Ang)-1 and Ang-2] would be abnormal in CAD patients with LVSD, being correlated with EF and wall motion abnormalities (wall motion score) independently of underlying CAD (coronary atheroma score). We also evaluated the specificity of angiogenic 'biomarkers' in their detection of LVSD [ejection fraction (EF) <40%] amongst CAD patients. METHODS: Using a cross sectional approach, we measured angiogenin, VEGF, Ang-1 and Ang-2 by ELISA in 194 CAD patients (aged 34-81 years) undergoing elective coronary angiography. RESULTS: Levels of angiogenin were inversely related with EF (r = -0.17, P = 0.02) and positively with coronary atheroma scores (r = 0.15, P = 0.04, but not independently of EF). Other angiogenic markers were unrelated to objective measures of LVSD but VEGF (P = 0.008) and Ang-2 (P = 0.015) were lower amongst those patients with heart failure. Angiogenin levels were related to wall motion scores (r = 0.16, P = 0.024). CONCLUSION: Heart failure has a modest impact on biomarkers of angiogenesis, in patients with CAD. Further research is warranted into the diagnostic and prognostic utility of biomarkers of angiogenesis, in this common cardiac condition.

Emergency intubation: a prospective multicentre descriptive audit in an Australian helicopter emergency medical service.

OBJECTIVE: To describe the safety profile of emergency airway management when performed by a prehospital team consisting of a doctor and a paramedic. Success rates, the incidence of difficult airways and the ability of prehospital doctors to determine a difficult airway are reported. METHODS: A prospective audit and descriptive study of three Australian helicopter emergency medical service (HEMS) bases, over a 9-month period. Doctors completed questionnaires regarding the number of endotracheal intubation (ETI) attempts on patients transported intubated and ventilated, Cormack and Lehane view of the cords during laryngoscopy and the anticipated and actual ease of ETI. RESULTS: A total of 114 (11.4%) patients transported by the HEMS was intubated and ventilated. Study questionnaires were completed on 89 of the 114 cases (78.1%), of which 32 (36%) were trauma related. HEMS were involved with 43 (48.3%) of the 89 intubations and performed 12.4% (n = 11) out of hospital. The HEMS ETI success rate was 97.6%. No surgical airways were performed. The actual incidence of difficult airways was higher (n = 4, 9.3%) than the anticipated incidence (n = 1, 2.3%). Six patients (14.0%) were successfully intubated by the doctor after the paramedic failed. CONCLUSIONS: Well-trained doctor paramedic teams, utilising standardised operating procedures, can safely perform rapid sequence induction and ETI in the prehospital and emergency environment. However, prehospital doctors are not always able to anticipate a difficult airway. The complication rate was similar to that in hospital emergency departments and to that of other physician-led HEMS.

Circulating serum adiponectin levels in patients with coronary artery disease: relationship to atherosclerotic burden and cardiac function.

BACKGROUND: Abnormal adipocyte function is implicated in both the pathophysiology of coronary heart disease (CHD) and cardiac function, where adiponectin provides a putative link. However, the utility of adiponectin as a discriminator of CHD severity is unclear and may be confounded by cardiac function. We hypothesized that plasma adiponectin would relate to indices of coronary artery disease severity (coronary atheroma scores, CAS), ejection fraction (EF) and regional wall motion abnormalities (RWMA) therein. METHOD: We measured adiponectin using a cross-sectional approach, we measured plasma adiponectin enzyme-linked immunosorbent assay in 204 consecutive patients (aged 34-81 years) undergoing elective coronary angiography. RESULTS: Levels of adiponectin decreased in an ordinal fashion across tertiles of increasing CAS (P = 0.047), but were nonsignificantly correlated to absolute values of CAS (P = 0.06). Adiponectin levels were unrelated to left ventricular dysfunction related measures of RWMA or EF. On multivariate analysis, (including factors relating to CHD risk, history and medication) adiponectin levels were independently inversely associated with triglycerides (P = 0.001), CAS tertiles (P = 0.01) and positively with age (P < 0.001). CONCLUSION: Levels of adiponectin decreased with coronary artery disease severity, without impact from systolic dysfunction, but levels may be moderated through established CHD risk factors such as smoking and triglycerides. Further work is warranted as to the clinical prognostic utility of this marker amongst CHD patients.

The short-term effect of hyperoncotic albumin, given alone or with furosemide, on oxygenation in sepsis-induced acute respiratory distress syndrome.

Two prospective non-randomised interventional case series were conducted consecutively at a single university hospital mixed intensive care unit, in patients with severe sepsis and acute respiratory distress syndrome. The first series describes the administration of 200 ml of 20% human albumin solution over 120 s in 13 patients, examining the hypothesis that raising plasma albumin should improve oxygenation. The second series describes the effect of administering 30 mg of furosemide intravenously along with the albumin in 15 patients, exploring whether this would produce more sustained improvement in oxygenation than albumin only. Oxygenation and haemodynamic parameters were measured for 4 h, during the period of peak oncotic effect. Hyperoncotic albumin given alone or with furosemide produced only transient improvement in oxygenation and haemodynamics, which was statistically significant only in the patients given albumin alone. Although the plasma albumin remained significantly elevated at 4 h in both series, no sustained improvement in oxygenation was seen.

Measurement of mother-infant interactions and the home environment in a European setting: preliminary results from a cross-cultural study.

BACKGROUND: Infant development is adversely affected in the context of postnatal depression. This relationship may be mediated by both the nature of early mother-infant interactions and the quality of the home environment. AIM: To establish the usefulness of the Global Ratings Scales of Mother-Infant Interaction and the Infant-Toddler version of the Home Observation for the Measurement of the Environment (IT-HOME), and to test expected associations of the measures with characteristics of the social context and with major or minor depression. METHOD: Both assessments were administered postnatally in four European centres; 144 mothers were assessed with the Global Ratings Scales and 114 with the IT-HOME. Affective disorder was assessed by means of the Structured Clinical Interview for DSM-IV Disorders. RESULTS: Analyses of mother-infant interaction indicated no main effect for depression but maternal sensitivity to infant behaviour was associated with better infant communication, especially for women who were not depressed. Poor overall emotional support also reduced sensitivity scores. Poor support was also related to poorer IT-HOME scores, but there was no effect of depression. CONCLUSIONS: The Global Ratings Scales were effectively applied but there was less evidence of the usefulness of the IT-HOME.

Relaparotomy for suspected intraperitoneal sepsis after abdominal surgery.

Relaparotomy may be beneficial in patients developing intraperitoneal sepsis after abdominal procedures. We determined whether joint clinical assessment by intensivist and surgeon (clinician assessment) identified patients with surgically correctable intraperitoneal sepsis. We also assessed the effect of patient age and sex, disease presentation and severity, interval to relaparotomy, and the number of relaparotomies on survival after relaparotomy. Data on clinical, laboratory, and radiologic abnormalities prior to relaparotomy, relaparotomy findings, and in-hospital survival were prospectively collected on a general hospital intensive care unit (ICU) database between January 1997 and January 2002. Altogether, 65 of 1482 (4.4%) patients admitted to the ICU after abdominal surgery underwent relaparotomy at a median of 5 days after the initial procedure. There was an 83% probability of identifying surgically treatable sepsis and 43% in-hospital mortality. Abdominal imaging contributed accurate information in 50% of cases where clinician assessment was uncertain. Patient age and multiorgan failure prior to relaparotomy-but not urgency of initial laparotomy or the acute physiology and chronic health evaluation (APACHE II) score prior to relaparotomy, interval to relaparotomy, or number of relaparotomies-affected the outcome. Clinician assessment after abdominal surgery had a high probability of predicting intraperitoneal sepsis at relaparotomy. The 43% mortality after relaparotomy was unlikely to be greater than with nonoperative treatment of intraabdominal sepsis, but the 78% mortality after relaparotomy in patients older than 75 years of age raised doubts about this approach in the elderly. The identification of intraperitoneal sepsis and performance of relaparotomy earlier after the initial abdominal surgery might reduce the high rate (60%) of multiorgan failure prior to relaparotomy and improve survival after it.
