Does the New National Cervical Screening Programme Guideline Detect Cases of High-Grade Squamous Intraepithelial Lesions That Previously Would Have Been Missed?

OBJECTIVE: The aim of this study was to determine the number of patients undergoing large loop excision of the transformation zone (LLETZ), for biopsy-confirmed high-grade squamous intraepithelial lesions (HSIL), where the original cervical screening test (CST) reported oncogenic human papillomavirus (HPV) and negative liquid-based cytology (LBC). This reflects the number of patients where a LLETZ procedure would not have occurred under the previous guideline. METHODS: Retrospective observational chart review of all patients (n = 477) who underwent LLETZ procedure in a single tertiary unit over a 36-month period. Prevalence of negative histopathology, positive margins, incidental cervical cancer, and accuracy of HSIL identification at colposcopy were measured. Diagnostic accuracy of HSIL diagnosis from initial colposcopic impression was calculated; factors influencing accuracy were evaluated using multivariable logistic regression analysis. There were no comparators. RESULTS: Of 477 LLETZs, 5.9% (n = 28) were for oncogenic HPV and normal LBC on referral CST. Demographics between the "study" (oncogenic HPV and normal LBC on referral CST) and the "standard" group were similar, except the study group was less likely to be using contraception (25% vs 47%, p = .023). In the study group, initial colposcopic cervical biopsy confirmed HSIL in 91.6% (n = 27) and low-grade squamous intraepithelial lesions in 3.6% (n = 1). Histopathological analysis of LLETZ specimens confirmed HSIL in 20 patients (71.4%) and low-grade squamous intraepithelial lesions in 2 (7.1%). No microinvasion was detected. CONCLUSIONS: The renewed National Cervical Screening Programme (NCSP), is detecting more "at risk" patients, predicted to lead to a further reduction in incidence of cervical cancer in adequately screened patients.

Outcomes to 5 years of outborn versus inborn infants <32 weeks in Western Australia: a cohort study of infants born between 2005 and 2018.

OBJECTIVE: We compared mortality and morbidity of inborn versus outborn very preterm infants <32 weeks' gestation in Western Australia (WA) between 2005 and 2018. DESIGN: Retrospective cohort study. PATIENTS: Infants <32 weeks' gestation who were born in WA. MAIN OUTCOME MEASURES: Mortality was assessed as death before discharge home from the tertiary neonatal intensive care unit. Short-term morbidities included combined brain injury (intracranial haemorrhage grade ≥3 and cystic periventricular leukomalacia) and other major neonatal outcomes. Developmental assessments at age 2, 3 and 5 years were evaluated. We performed multivariable logistic regression analysis of outborn status on outcomes, controlling for gestational age, birth weight z-score, sex and multiple birth. RESULTS: A total of 4974 infants were born in WA between 22 and 32 weeks' gestation between 2005 and 2018 of which 4237 (89.6%) were inborn and 443 (10.4%) were outborn. Overall mortality to discharge was higher in outborn infants (20.5% (91/443) vs 7.4% (314/4237); adjusted OR (aOR) 2.44, 95% CI 1.60 to 3.70, p<0.001). Outborn infants had higher rates of combined brain injury than those inborn (10.7% (41/384) vs 6.0% (246/4115); aOR 1.98, 95% CI 1.37 to 2.86), p<0.001). No difference in up to 5-year developmental measures was detected. Follow-up data were available for 65% of outborn and 79% of inborn infants. CONCLUSIONS: Outborn preterm infants <32 weeks in WA had increased odds of mortality and combined brain injury than those inborn. Developmental outcomes up to 5 years were similar between groups. Loss to follow-up may have impacted the long-term comparison.

The effect of obesity on cost of total laparoscopic hysterectomy.

STUDY OBJECTIVE: To test for the association between increasing patient body mass index (BMI) and the cost of total laparoscopic hysterectomy (TLH). Secondary outcomes include the relationship between increasing BMI and both peri- and post-operative morbidity. MATERIALS AND METHODS: Retrospective cohort study of patients (N = 510) who underwent TLH between January 2017 and December 2018 at a single public tertiary teaching hospital. RESULTS: Morbid obesity (n = 63) was associated with significantly higher total admission costs ($19 654 vs $17 475 Australian dollars, P = 0.002), operative costs ($9447 vs $8630, P = 0.017) and total costs including readmissions ($20 476 vs $18 399, P = 0.016) when compared to patients with normal BMI (n = 103) and adjusting for age, indication for surgery, additional procedures and conversion to total abdominal hysterectomy. Costs for overweight (n = 134) and obese (n = 210) BMI groups did not differ from costs for the normal BMI group. Increased operative costs observed in the morbidly obese group, were largely driven by the time associated with set-up, transfer and anaesthetic time while surgical and recovery times were not statistically significant. CONCLUSION: The total cost of TLH is increased in the morbidly obese category of patients. The operative costs appear to be related to pre-operative measures such as theatre set-up and anaesthetic requirements. TLH in the obese and morbidly obese category group is not associated with increased intra-operative or post-operative complications. There may be a role for exploring improvements in managing morbidly obese patients in the pre-operative setting.

Association of gastric residual volumes with necrotising enterocolitis in extremely preterm infants-a case-control study.

Necrotising enterocolitis (NEC) is a potentially serious illness with significant mortality and morbidity in preterm infants. Previous studies have reported association of volume and colour (bile and blood stained) of gastric residuals (GR) with NEC. We aimed to study this association in our cohort of extremely preterm (EP) infants. In a case-control study using retrospective data (January 2006-December 2011), EP (gestation < 28 weeks) infants with confirmed NEC ≥ stage II (cases) were compared with infants without NEC (controls) matched for birth weight (BW) and gestational age (GA). Forty cases of NEC ≥ stage II diagnosed at a median (IQR) age of 16.5 days (10.3-23) were compared with 40 controls matched for gestation (± 3 days) and birth weight (± 680 g). Median maximum GR volume (GRV) from birth to the day of occurrence of NEC was significantly higher in cases vs. controls (5.9 vs.3.7 ml; p < 0.001). Increased maximum GRV was associated with NEC ≥ Stage II in adjusted analysis (aOR 1.36, 95%CI 1.06-1.75, p = 0.017). There was no significant difference in GRV between cases and controls throughout the clinical course, including 72, 48 and 24 h before the onset of NEC. However, green (65.0% vs. 27.5%, p = 0.001) and haemorrhagic GRs (45.0% vs. 27.5%, p = 0.092) were higher 24 h before the diagnosis of NEC.Conclusion: GRV was not associated with NEC ≥ stage II. However, green and haemorrhagic GRs were significantly higher 24 h before the diagnosis of the illness. Adequately powered prospective studies are needed to confirm the significance of our findings. What is Known: •It is unclear whether large volume, dark-coloured and blood-stained GRs are associated with NEC. •The value of routine monitoring of gastric residuals in preterm infants is currently being questioned. What is New: •Volume of gastric residuals was not associated with significant NEC. •Green and haemorrhagic GRs were significantly higher 24 hours before diagnosis of NEC.

Effect of Enteral Vitamin A on Fecal Calprotectin in Extremely Preterm Infants: A Nested Prospective Observational Study.

BACKGROUND: Vitamin A has anti-inflammatory and immune-modulating properties. We aimed to assess whether enteral water-soluble vitamin A supplementation in extremely preterm infants decreases fecal calprotectin, a marker of intestinal inflammation. METHODS: This was a prospective observational study nested in a randomized, double-blind, placebo-controlled clinical trial investigating enteral vitamin A (5,000 IU/day) for reducing the severity of bronchopulmonary dysplasia (BPD) in extremely preterm infants. Fecal calprotectin levels were measured using enzyme-linked immunosorbent assay after 28 days of Vitamin A or placebo supplementation. RESULTS: Fecal calprotectin was measured in 66 infants (Vitamin A: 33, Placebo: 33). The mean (standard deviation) gestational age (25.5 [1.55] vs. 25.8 [1.48]; p = 0.341) (week), birth weight (810 [200] vs. 877 [251]; p = 0.240) (gram), and factors influencing fecal calprotectin levels were comparable between the vitamin A versus placebo group infants. All infants were exclusively fed with mother's or donor's human breast milk if mother's milk was unavailable using a standardized feeding regimen and received prophylactic probiotic supplementation. Fecal calprotectin levels (median; 25th-75th centiles) (micrograms/gram of feces) were not significantly different between vitamin A (152; 97-212) and placebo groups (179; 91-313) (p = 0.195). Two infants in the vitamin A group developed definite necrotizing enterocolitis compared to none in the placebo group. Incidence of BPD at 36 weeks postmenstrual age was similar between the groups (vitamin A: 18/33, placebo: 13/33, p = 0.218). CONCLUSION: Enteral supplementation with water-soluble vitamin A did not affect fecal calprotectin levels in extremely preterm infants. Studies with a larger sample size are required to confirm the findings.

Enteral Vitamin A for Reducing Severity of Bronchopulmonary Dysplasia: A Randomized Trial.

BACKGROUND AND OBJECTIVES: Evidence suggests that intramuscular vitamin A reduces the risk of bronchopulmonary dysplasia (BPD) in preterm infants. Our objective was to compare enteral water-soluble vitamin A with placebo supplementation to reduce the severity of BPD in extremely preterm infants. METHODS: We conducted a double-blind randomized controlled trial in infants <28 weeks' gestation who were to receive either enteral water-soluble vitamin A (5000 IU per day) or a placebo. Supplementation was started within 24 hours of introduction of feeds and continued until 34 weeks' postmenstrual age (PMA). The primary outcome was the severity of BPD, assessed by using the right shift of the pulse oximeter saturation versus the inspired oxygen pressure curve. RESULTS: A total of 188 infants were randomly assigned. The mean ± SD birth weight (852 ± 201 vs 852 ± 211 g) and gestation (25.8 ± 1.49 vs 26.0 ± 1.39 weeks) were comparable between the vitamin A and placebo groups. There was no difference in the right shift (median [25th-75th percentiles]) of the pulse oximeter saturation versus inspired oxygen pressure curve (in kilopascals) between the vitamin A (11.1 [9.5-13.7]) and placebo groups (10.7 [9.5-13.1]) (P = .73). Enteral vitamin A did not affect diagnosis of BPD or other clinical outcomes. Plasma retinol levels were significantly higher in the vitamin A group versus the placebo group on day 28 and at 34 weeks' PMA. CONCLUSIONS: Enteral water-soluble vitamin A supplementation improves plasma retinol levels in extremely preterm infants but does not reduce the severity of BPD.

Surgery in pregnancy: Identifying factors contributing to variation and delay in diagnosis and management of appendicitis in pregnancy.

BACKGROUND: Suspected appendicitis is the most common indication for surgery for non-obstetric conditions during pregnancy. Delay in management increases the risk of appendiceal perforation and pregnancy loss. Stand-alone specialty obstetric hospitals often don't have surgical teams on site. It has been suspected that this may be a factor that leads to delayed diagnosis and management of non-obstetric surgical conditions in pregnancy. AIMS: To assess the differences in time to diagnosis, imaging, surgical management and outcomes between a stand-alone tertiary obstetric hospital and a tertiary general hospital for pregnant patients presenting with suspected appendicitis who underwent an appendicectomy. MATERIALS AND METHODS: A retrospective study of all women who underwent appendicectomy in pregnancy for suspected appendicitis over a four-year period. RESULTS: Women who attended the specialist hospital were later in gestation (medians 29 weeks vs 18 weeks, P = 0.004) and less likely to have imaging (84% vs 56%, P = 0.047) with no difference in the rates of confirmation of diagnosis of appendicitis using imaging. Women who presented to the specialist hospital were more likely to be managed with a laparotomy, admitted to high dependency unit, have a longer hospital stay and tended to be later in gestation. There was no difference in rates of positive appendicectomies, appendiceal perforation or management in under the recommended 24 h. CONCLUSIONS: The specialty obstetric hospital has a much higher rate of laparotomy and longer length of stay. The majority of patients presenting to both hospitals did not undergo surgery within 24 h and delay in imaging was a major contributor.

Impaired Cytokine Responses to Live Staphylococcus epidermidis in Preterm Infants Precede Gram-positive, Late-onset Sepsis.

BACKGROUND: Late-onset sepsis (LOS) with Staphylococcus epidermidis is common in preterm infants, but the immunological mechanisms underlying heightened susceptibility are poorly understood. Our aim is to characterize the ontogeny of cytokine responses to live S. epidermidis in preterm infants with and without subsequent Gram-positive LOS. METHODS: We conducted a prospective, observational cohort study of preterm infants (<30 weeks gestational age [GA]) with blood sampling on Days 1, 7, 14, 21, and 28 of life. Cytokine responses in peripheral whole blood stimulated with live S. epidermidis were analyzed by 11-plex immunoassay. RESULTS: Of 129 infants (mean GA, 26.2 weeks; mean birth weight, 887g), 23 (17.8%) had confirmed LOS with Gram-positive organisms and 15 (11.6%) had clinical sepsis, with median onsets at 13 and 15 days, respectively. Blood cytokine responses to an in vitro S. epidermidis challenge were similar between infected and uninfected infants on Day 1, but diverged thereafter. Infants with subsequent LOS displayed broadly reduced S. epidermidis-induced responses from Day 7 onwards, compared to those who did not develop LOS. This pattern was observed with chemokines (interleukin [IL]-8, monocyte chemotactic protein-1, and macrophage inflammatory protein-1α), pro-inflammatory cytokines (IL-1, IL-6, and tumor necrosis factor-α) and the regulatory cytokine IL-10. CONCLUSIONS: Cytokine responses to a live S. epidermidis challenge are impaired in infants with LOS and precede the onset of clinical illness. Quantifying pathogen-specific cytokine responses at Day 7 may identify those high-risk preterm infants at the greatest risk of LOS, and prospective replication is warranted.

LLETZ make it simple: Anxiety, pain and treatment outcomes with outpatient large loop excision of the transformation zone under local anaesthesia.

BACKGROUND: Large loop excision of the transformation zone (LLETZ) is the preferred treatment for cervical intraepithelial neoplasia due to its effectiveness and ability to be performed in an outpatient setting under local anaesthesia (LA). Although current guidelines recommend that most LLETZ can be performed under LA, there is paucity in clinical data of patients' perspectives of outpatient LLETZ. AIM: Determining patient acceptability of outpatient LLETZ through assessment of anxiety and pain scores, and comparing treatment outcomes with current standards in terms of margins status, negative histology, short-term morbidity rates and follow-up attendance. MATERIALS AND METHODS: This study was conducted at a tertiary hospital over two years (2014-2016). Patients undergoing outpatient LLETZ completed a three-part questionnaire (before, immediately after and 4-6 weeks post-procedure). RESULTS: One hundred and five patients underwent outpatient LLETZ. Mean pain score was 2 (range 0-8). Pre-procedure anxiety was common but most resolved post-procedure. Women who did not have a prior LLETZ discussion were more likely to report moderate-severe anxiety levels pre-procedure, compared with women who did (odds ratio 3.00, 95% CI 1.11-8.09, P = 0.030). There were no differences found in pain scores when comparing pre-procedure anxiety levels, prior discussion of LLETZ or mode of anaesthesia. Specimen margins were involved in 42.9%. No association was found between positive cervical margin status and age, pre-procedure anxiety or post-procedure pain scores. Most patients were satisfied and attended follow-up appointments. CONCLUSION: Large loop excision of the transformation zone under LA is a well-tolerated procedure with high satisfaction and follow-up rates. Clinicians need to initiate early discussions regarding treatment to minimise procedure-related anxiety.

Developmental dysplasia of the hip in preterm breech infants.

BACKGROUND: Whether preterm infants born with breech presentation are at similar risk of developmental dysplasia of the hip (DDH) as the term breech infants is not known. The information will be vital for DDH screening guidelines. METHODS: A retrospective audit of infants born in the breech position was performed to compare the incidence of DDH in the following gestational age groups: 23-27, 28-31, 32-36 and ≥37 weeks. RESULTS: A total of 1144 neonates were included in the study. The incidence of DDH did not differ between the groups (11.6%, 9.4%, 13.6% and 11.5%, in 23-27, 28-31, 32-36 and ≥37 weeks, respectively, p=0.40). Sixty infants required intervention for DDH. Multiple logistic regression after correcting for potential confounders showed that gestational age group did not influence the risk of DDH, and requirement of therapy. CONCLUSION: Preterm infants born with breech presentation appear to have a similar incidence of DDH to term breech infants. .

High frequency jet ventilation in preterm infants: experience from Western Australia.

Objective: To assess if high frequency jet ventilation (HFJV) is associated with reduced odds of death or discharge home on oxygen in preterm infants. Methods: A case control study (1 February 2010 - 1 June 2014) comparing the primary outcome as "death or discharge home on oxygen" in preterm infants who needed HFJV (Cases) versus those who did not (Controls). Controls were matched to cases (1:1) on gestation, birthweight, gender, place of birth, growth status, antenatal glucocorticoids, and dexamethasone as treatment for severe bronchopulmonary dysplasia (BPD). Logistic regression analysis was used to control for confounders. Results: Data on all preterm infants who needed HFJV (Cases: n = 50) and 50 controls during the study period were analysed. Primary outcome was more frequent in cases versus controls, but not significant after adjusting for mean airway pressure and adjuvant therapy (e.g. diuretics) [aOR: 1.46 (0.23-9.14), p = .687]. Death before discharge [odds ratios (OR): 6.00 (1.34-55.2), p = .013] was more frequent in cases; discharge on home oxygen [OR: 0.88 (0.27-2.76), p = 1.000] was comparable between groups. Duration of oxygen [adjusted hazard ratios (aHR): 1.23 (0.69-2.17), p = .475] and incidence of treatment warranting retinopathy of prematurity [aOR: 0.10 (0.01-1.96), p = .127] was not significant between cases versus controls. Conclusions: HFJV was not associated with reduced odds of death or discharge home on oxygen in preterm infants in our study. Adequately powered randomized trials are required to assess the efficacy and safety of HFJV in preterm infants.

Preclinical evaluation of drugs to block inflammation-driven preterm birth.

Intrauterine inflammation, the major cause of early preterm birth, can have microbial and sterile aetiologies. We assessed in a Transwell model the anti-inflammatory efficacies of five drugs on human extraplacental membranes delivered after preterm spontaneous labour (30-34 wk). Drugs [TPCA1 (IKKß inhibitor), 5 z-7-oxozeaenol (OxZ, TAK1 inhibitor), inhibitor of NF-κB essential modulator binding domain (iNBD), SB239063 (p38 MAPK inhibitor) and N-acetyl cysteine (free radical scavenger free radicals)] were added after 12 h equilibration to the amniotic compartment. Concentrations of IL-6, TNF-α, MCP-1, IL-1ß and PGE2 in the media, and IL6, TNFA and PTGS2 mRNA expression levels in membranes, were determined after 12 h. Data were analysed using mixed models analyses. Thirteen of the 28 membranes had histological chorioamnionitis (HCA+); five were positive for bacterial culture and six for fetal inflammatory reaction. Baseline PGE2 and cytokine production was similar between HCA- and HCA+ membranes. Anti-inflammatory effects were also similar between HCA- and HCA+ membranes. TPCA1 and OxZ were the most effective drugs; each inhibited amniotic secretion of 4/5 pro-inflammatory mediators and mRNA levels of 2/3, regardless of stimulus. We conclude that treatment with TPCA1 or OxZ, in combination with antibiotics, may minimise the adverse effects of intrauterine inflammation in pregnancy.

Ureaplasma parvum genotype, combined vaginal colonisation with Candida albicans, and spontaneous preterm birth in an Australian cohort of pregnant women.

BACKGROUND: Detection of Ureaplasma, Mycoplasma and Candida spp. in the vagina during pregnancy has previously been associated with preterm birth (PTB). However, the prevalence of these microorganisms and the associated obstetric risks (likely to be population-specific) have not been determined in Australian women; furthermore, in the case of Ureaplasma spp., very few studies have attempted characterisation at the species level and none have examined genotype/serovar status to further refine risk assessment. METHODS: In order to address these issues we sampled the vaginal fluid of 191 pregnant Australian women at three time points in pregnancy. Culture methods were used for detection of Ureaplasma spp. and Candida spp., and real-time PCR was used for speciation of U. parvum and U. urealyticum, non-albicans Candida spp., Mycoplasma hominis and Mycoplasma genitalium. High-resolution melt PCR was used to genotype U. parvum. Data on various lifestyle factors (including sex during pregnancy and smoking), antimicrobial use and pregnancy outcome were collected on all participants. Chi-square tests were used to assess the association of vaginal microorganisms with PTB. RESULTS: Detection of Ureaplasma spp. was higher among spontaneous PTB cases, specifically in the presence of U. parvum [77 % preterm (95 % confidence interval (CI) 50-100 %) vs. 36 % term (CI: 29-43 %), p = 0.004], but not U. urealyticum. The association with PTB strengthened when U. parvum genotype SV6 was detected (54 % preterm (CI: 22-85 %) vs. 15 % term (CI: 10-20 %), p = 0.002); this genotype was also present in 80 % (4/5) of cases of PTB <34 weeks gestation. When present with Candida albicans in the same sample, the association with PTB remained strong for both U. parvum [46 % preterm (CI: 15-78 %) vs. 13 % term (CI: 8-18 %), p = 0.005] and U. parvum genotype SV6 [39 % preterm (CI: 8-69 %) vs. 7 % term (CI: 3-11 %), p = 0.003]. With the exception of Candida glabrata, vaginal colonisation status for all organisms was stable throughout pregnancy. Smoking significantly increased the likelihood of detection of all target organisms. CONCLUSIONS: These data suggest that the presence of different species and serovars of Ureaplasma spp. in the vagina confers an increased risk of spontaneous PTB, findings which may be useful in risk assessment for identifying women who would benefit from antimicrobial treatment.

The long-term neurodevelopmental and psychological outcomes of gastroschisis: A cohort study.

OBJECTIVES: Previous gastroschisis specific neurodevelopmental studies have focused on the first 3years of life. The aim of this study was to assess the intellectual, behavioral and neurological outcomes of older children and adolescents born with gastroschisis. STUDY DESIGN: Of 99 gastroschisis survivors born in Western Australia, 1992 to 2005, and who were at least 5years old, 42 agreed to take part in this study. The study assessed: intellectual ability, with age appropriate Wechsler intelligence scales; neurological status; hearing; vision; behavioral status with the Strengths and Difficulties Questionnaire (SDQ); and parenting style with the Parenting Relationship Questionnaire (PRQ). All results were compared to normative means. RESULTS: Median age at follow-up was 10years (range 5-17). No child had evidence of cerebral palsy or hearing loss; 1 child had amblyopia. Psychometric tests were completed in 39 children: mean full scale IQ was 98.2 (standard deviation [SD] 10.7); the working memory index was the only subscale to show a significant decrease from the normative mean (mean 95.5, SD 12.4, p=0.038). The mean SDQ behavioral scores were significantly lower for 3 of 5 domains and the Total Difficulties score. PRQ scores were significantly abnormal for 4 of 7 domains: Communication, Discipline, Satisfaction with School and Relational Frustration. CONCLUSIONS: Overall intellectual abilities were within a normal range. The decrease in working memory index and the behavioral and parenting relationship impairments could be an effect of perinatal factors, gastroschisis management and complications or the complexity of the socio-economic environment.

Nebulized pentoxifylline for reducing the duration of oxygen supplementation in extremely preterm neonates.

OBJECTIVE: To evaluate the efficacy and safety of nebulized pentoxifylline for reducing the duration of oxygen supplementation in extremely preterm neonates at high risk of bronchopulmonary dysplasia (BPD). STUDY DESIGN: Single-center, randomized, double-blind, placebo-controlled trial was conducted. Infants of 23(0) to 27(6) weeks' gestational age requiring mechanical ventilation or ≥30% supplemental oxygen on continuous positive airway pressure at 72-168 hours were randomized to receive 20 mg/kg (1 mL/kg) nebulized pentoxifylline or an equal volume of normal saline placebo every 6 hours for 10 consecutive days via a vibrating mesh nebulizer. The primary outcome was the duration of oxygen supplementation at 40 weeks' postmenstrual age. We used Cox proportional hazards regression modeling to analyze outcomes. RESULTS: All infants had adequate data for analysis of the primary outcome. Intention-to-treat analysis revealed no differences in duration of oxygen supplementation at 40 weeks' postmenstrual age between pentoxifylline (n=41) and placebo (n=40) groups (median 2262 vs 2160 hours, adjusted hazard ratio: 1.14, 95% CI 0.72-1.80, P=.63). There was no difference in mortality and further secondary outcomes. No adverse effects were noted. CONCLUSIONS: Nebulized pentoxifylline is safe but did not reduce the duration of oxygen supplementation in extremely preterm infants at high risk of BPD. Dose-ranging studies and large, well-designed clinical trials are required to determine whether the use of nebulized or systemic pentoxifylline as a prophylactic therapy offers small but relevant benefits for prevention of BPD.

The long term physical consequences of gastroschisis.

PURPOSE: To determine the progress, physical and metabolic outcomes of gastroschisis survivors. METHODS: Fifty children born with gastroschisis were assessed with a health questionnaire, physical assessment, bone density and nutritional blood parameters at a median age of 9years (range 5-17). RESULTS: After initial abdominal closure, 27/50 (54%) required additional surgical interventions. Ten (20%) children had complex gastroschisis (CG). Abdominal pain was common: weekly in 41%; and requiring hospitalization in 30%. The weight, length and head circumference z-scores improved by a median 0.88 (p=0.001), 0.56 (p=0.006) and 0.74 (p=0.018) of a standard deviation (SD) respectively from birth; 24% were overweight or obese at follow up. However, those with CG had significantly lower median weight z-scores (-0.43 v 0.49, p=0.0004) and body mass index (BMI) (-0.48 v 0.42, p=0.001) at follow up compared to children with simple gastroschisis. Cholesterol levels were elevated in 24% of children. Bone mineral density was reassuring. There were 15 instances of low blood vitamin and mineral levels. CONCLUSIONS: Although gastroschisis survival levels are high, many children have significant ongoing morbidity. Children with simple gastroschisis showed significant catch up growth and a quarter had become overweight.

Cervilenz™ is an effective tool for screening cervical-length in comparison to transvaginal ultrasound.

OBJECTIVE: To assess the accuracy and reliability of cervico-portio (CP) length estimated using the Cervilenz™ compared with transvaginal ultrasound (TVU) cervical-length in women at high and low risk of spontaneous preterm birth (SPTB). METHODS: Cervical-length was assessed longitudinally across gestation utilizing CP-length measured with Cervilenz™ and TVU. Altman-Bland plots were used to compare Cervilenz™ and TVU cervical-length. Regression analysis was used to assess the effect of gestational age, previous SPTB and previous cervical surgery on Cervilenz™ accuracy. Receiver operator curves (ROC) were utilized to determine the CP-length measured by Cervilenz™ with the optimum sensitivity and specificity for predicting TVU cervical-length <25 mm. ROCs were utilised to compare the ability of Cervilenz™ with TVU to predict SPTB. RESULTS: Seventy-five women were recruited (low risk N = 57, high risk N = 18). A total of 259 TVU and 253 Cervilenz™ measurements were taken with up to six measures in each woman. The Cervilenz™ CP-length was on average 9 mm shorter than TVU measured cervical-length. The difference decreased with advancing gestational age (p < 0.001). Cervilenz™ CP-length <24 mm was a good predictor of TVU cervical-length <25 mm (area under the curve (AUC) = 0.867). After accounting for baseline Cervilenz™ measurements, the relationship between Cervilenz™ and TVU measures was not influenced by pregnancy risk status. There were no significant differences between Cervilenz™ (AUC = 0.716) and TVU (AUC = 0.706) in predicting SPTB. CONCLUSION: Cervilenz™ is an effective tool for screening cervical-length in comparison to TVU. Cervilenz™ may facilitate greater access to cervical-length measurement and assessment of risk of preterm birth.

Preoperative anaemia is common in patients undergoing major gynaecological surgery and is associated with a fivefold increased risk of transfusion.

AIMS: To ascertain the incidence of preoperative anaemia in a cohort of patients undergoing major gynaecological surgery in a tertiary Australian hospital over a two-year period and to investigate whether it is associated with an increased rate of transfusion or complications. METHODS: Using the Western Australian Patient Blood Management (PBM) Data System, we obtained data for 843 women undergoing major gynaecological surgery over a two-year period at King Edward Memorial Hospital, Subiaco, Western Australia. We used regression analysis to investigate the relationship between preoperative anaemia, red cell transfusion, length of hospital stay and complications. RESULTS: Preoperative anaemia was present in 18.1% of women and was associated with a significantly increased risk of receiving a red cell transfusion (OR = 5.74, P < 0.001). After adjusting for confounders, preoperative anaemia was not independently associated with increased complications or hospital length of stay, but receiving a red cell transfusion was (P < 0.001). CONCLUSION: This study demonstrates preoperative anaemia is common in women undergoing elective major gynaecological surgery and is associated with increased red cell transfusions. A system to detect and treat anaemia prior to surgery in these patients should be implemented, and interventions should be evaluated to ensure they are effective.

Using the Edinburgh postnatal depression scale to screen for perinatal anxiety.

We replicated the factor structure of the anxiety subscale of the Edinburgh Postnatal Depression Scale (EPDS) in a large convenience sample of Western Australian women who participated in the beyondblue National Postnatal Depression Program. In addition, we determined an appropriate cut-off score for the anxiety subscale. Factor analyses conducted on the EPDS responses yielded depression and anxiety factors as identified in previous research. Two-factor solutions accounted for over 50% of the variance at two time frames: antenatally (N=4,706) and at postnatal follow-up (N=3,853). The anxiety and depression factors had similar factor structures antenatally and postnatally and were consistent with previous published findings. The concurrent validity of the anxiety subscale was demonstrated by its significant relationship to anxiety-related items on a psychosocial risk factors questionnaire. Anxiety dropped significantly from the antenatal to the postnatal time period. These findings confirm the anxiety subscale of the EPDS and point to its utility in screening for anxiety symptoms using a cut-off score ≥4 which captured the top quartile of the antenatal sample.
