Sexual and reproductive health services in New Zealand primary care settings: A mixed-methods survey

BACKGROUND

New Zealand's recently released Women's Health Strategy aims to provide accessible, equitable care which prioritises prevention, early intervention and areas of unmet need. An example of such care is the management of common sexual and reproductive health (SRH) issues by appropriately trained primary care practitioners in the community.

AIMS

The aim was to identify primary care SRH program initiatives currently operating in New Zealand, how they are accessed and funded, whether they have been co-designed using mātauranga (knowledge) Māori principles and whether any have undergone formal evaluation.

METHODS

A mixed-methods electronic anonymous survey of primary care practitioners and secondary care obstetrics and gynaecology clinical directors was distributed in April 2023. Qualitative analysis of free text answers was undertaken.

RESULTS

Few funded SRH services are available in community settings in New Zealand. Access and eligibility criteria to those which exist varies by region. A lack of co-design and governance was reported, along with difficulties in access to skills training and specialist advice.

CONCLUSIONS

The current SRH landscape in New Zealand appears fragmented and lacks an overarching strategic focus. To achieve the aims of the Women's Health Strategy, a suite of core community-based SRH programs should be developed and formally evaluated, focusing on equitable access, integration and specific outcomes. These should be co-designed using mātaurangi Māori principles.

Antiphospholipid antibodies do not cause retargeting of placental extracellular vesicles in the maternal body

Antiphospholipid antibodies (aPL) are autoantibodies that cause pregnancy disorders by a poorly defined mechanism that involves the placenta. The human placenta is covered by a single multinucleated cell, the syncytiotrophoblast, which extrudes vast numbers of extracellular vesicles (EVs) into the maternal blood. Extracellular vesicles are tiny packages of cellular material used by cells for remote signalling. In normal pregnancy, placental EVs assist maternal adaptations to pregnancy. We have previously shown that aPL alter the cargo of placental EVs, increasing the load of danger signals. These changes in EV cargo may explain how aPL contribute to the increased risk of recurrent miscarriage, preeclampsia and stillbirths observed in aPL-affected pregnancies. An additional possibility, that aPL alters the targeting of placental EVs to maternal organs to cause maternal maladaptation to pregnancy was investigated in this study.

Placental extracellular vesicles retain biological activity after short-term storage (14 days) at 4 °C or room temperature

INTRODUCTION

To investigate the role of placental extracellular vesicles (EVs), especially in pathological pregnancy, the use of freshly isolated EVs is often limited due to the sporadic and unpredictable availability of placental samples. Therefore, it is important to understand and use optimised storage conditions for placental EVs. In this study, we investigated different conditions for the short-term storage of placental micro- and nano-EVs and examined their biological activity.

METHODS

Placental EVs were collected from first trimester placentae. EVs were suspended in PBS and aliquoted, and then stored for up to 14 days at room temperature, 4 °C or -20 °C. Total protein and DNA levels were measured at various time points. The ability of stored placental EVs to alter endothelial cell activation was quantified by monocyte adhesion assays.

RESULTS

There was no difference in the concentration of placental micro- or nano-EVs between each time point, when stored at either room temperature or 4 °C. However, there was a significant loss of placental EVs after storage at -20 °C. There was no difference in protein or DNA levels of placental EVs when stored at either room temperature or 4 °C. Biological activity of placental EVs was retained for up to 14 days at either room temperature or 4 °C measured by monocyte adhesion assays.

DISCUSSION

We have shown that placental micro- and nano-EVs are stable and retain biological activities following storage in PBS or media for 14 days at either room temperature or 4 °C.

Oh what a tangled web we weave when first we practice to deceive…

‘Oh what a tangled web we weave when first we practice to deceive’. Marmion, Sir Walter Scott 1808. Conflict is unpleasant, it is aversive, we tend to avoid it. Yet inevitably tension between individuals or between individuals and society is inevitable as the wants of one collide with the purpose of the other. Most of these tensions resolved peacefully but a societal level aggression can sometimes spill out. In the hinterlands between individuals and larger groups these can play out more safely through the courts or sometimes the avoidance of conflict can be the only tactic that the individual can use. As doctors we are used to sing medical problems with patients have true disease believe they have two disease and want to get well-the standard social model of medicine. But sometimes this plays out differently there are those who may fabricate symptoms to avoid punishment or for reward: malingering. There are those who believe they have a disease but the distress is disproportionate to any possible recognised component; somatic symptom disorder. There are those whose anxiety about whether they have a disease or not is paralysing and perhaps most distressing for all of the groups who self-harm or malinger with authentic illness or disease. In this talk Dr Wise will, using case examples, look at a couple of the tools that exist to assist psychiatrists in piloting a pathway through the stormy waters of abnormal illness in litigation.

Diagnostic dilemma’s in the new world of ICD-11 personality disorders

Personality disorders have ever been a troublesome group. From the early 90’s ICD 10 tidied up the group. DSM-IV, IV-TR, aand then DSM 5, changed the style but not substance, leaving clinicians to grapple with thorny questions of multiple diagnoses, treatment and prognosis. International views on the utility of the diagnosis often depended upon the institution or the funding mechanism. Were fears of exclusion and stigma dominated or where there was no treatment, there was under-diagnosis, such as in the United Kingdom and the Republic of Ireland. Where a label was a ticket of entry to treatment and funding, diagnostic generosity prevailed, such as in Australia, New Zealand and the United States. Gender discrepancies disappeared with structured interviews, and interest grew in the category which seem to only include the most severe forms. For many years the DSM taskforce tried to shift the construct but shied away from the cliff edge; a bold new initiative did not materialise. It was left to the ICD-11 to generate a much more adventurous and positive view of how characterological traits shift under pressure, moving from something that may at first have helped patients to ‘survive’ to something that became maladaptive and harmful. With a court tested case Dr Wise will demonstrate the differences between ICD-10 and ICD-11 highlighting the more important differences: onset, course and severity descriptors. PD’s are no longer lifelong impairments. Prepare for ‘The shock of the new’!

Detecting national human enteric disease outbreaks linked to animal contact in the United States of America

Enteric pathogens, such as non-typhoidal Salmonella, Campylobacter and Escherichia coli, can reside in the intestinal tract of many animals, including livestock, companion animals, small mammals and reptiles. Often, these animals can appear healthy; nonetheless, humans can become infected after direct or indirect contact, resulting in a substantial illness burden. An estimated 14% of the 3.2 million illnesses that occur in the United States of America (USA) each year from such enteric pathogens are attributable to animal contact. Surveillance for enteric pathogens in the USA includes the compilation and interpretation of both laboratory and epidemiologic data. However, the authors feel that a collaborative, multisectoral and transdisciplinary - or One Health - approach is needed for data collection and analysis, at every level. In addition, they suggest that the future of enteric illness surveillance lies in the development of improved technologies for pathogen detection and characterisation, such as genomic sequencing and metagenomics. In particular, using whole-genome sequencing to compare genetic sequences of enteric pathogens from humans, food, animals and the environment, can help to predict antimicrobial resistance among these pathogens, determine their genetic relatedness and identify outbreaks linked to a common source. In this paper, the authors describe three recent, multi-state human enteric illness outbreaks linked to animal contact in the USA and discuss how integrated disease surveillance was essential to outbreak detection and response. Additional datasharing between public health and animal health laboratories and epidemiologists at the local, national, regional and international level may help to improve surveillance for emerging animal and human health threats and lead to new opportunities for prevention.

0408 Myths About Infant, Child, and Adolescent Sleep: Addressing False Beliefs That Hinder Sleep Health During These Crucial Developmental Stages

Introduction

Sleep is vital for healthy development from infancy through adolescence. Despite its importance, false beliefs that conflict with scientific evidence (myths) may be common among caregivers and impair sleep health during these crucial stages.

Methods

Researchers compiled a list of potential myth statements using internet searches of popular press and scientific literature. We utilized a Delphi process with experts (n=12) from the fields of pediatric, sleep, and circadian research and clinical practice. Selection and refinement of myths by sleep experts proceeded in three phases, including: focus groups (Phase 1); email-based feedback to edit, add, or remove myths (Phase 2); and closed-ended questionnaires (Phase 3) where experts rated myths on two dimensions: (1) falseness and (2) public health significance using 5-point Likert scale: 1 (“not at all”) to 5 (“extremely false/important”).

Results

Thirty-two sleep myths were identified across three developmental categories: infant (14 myths), child (6 myths), and adolescent (12 myths). Mean expert ratings illuminated the most pressing myths in each developmental category: infant sleep (“Sleep training causes psychological harm, including reduced parent-child attachment:” falseness =4.7, s.d.=0.7; public health significance=4.0, s.d.=1.1); child sleep (“Heavy, loud snoring for my child means he’s sleeping deeply:” falseness=4.8, s.d.=0.6; public health significance=4.7, s.d.=0.7), and teenager sleep (“Falling asleep in class means your teenager is lazy and not motivated:” falseness=4.8, s.d.=0.5; public health significance=4.3, s.d.=0.8).

Conclusion

The current study identified commonly-held myths about infant, child, and adolescent sleep that are not supported by (or worse, counter to) scientific evidence. If unchecked, these myths may hinder sleep at a critical developmental stage. Future research may include public health education to correct myths and promote healthy sleep among infants, children, and teenagers.

A radio ridge connecting two galaxy clusters in a filament of the cosmic web

Galaxy clusters are the most massive gravitationally bound structures in the Universe. They grow by accreting smaller structures in a merging process that produces shocks and turbulence in the intracluster gas. We observed a ridge of radio emission connecting the merging galaxy clusters Abell 0399 and Abell 0401 with the Low-Frequency Array (LOFAR) telescope network at 140 megahertz. This emission requires a population of relativistic electrons and a magnetic field located in a filament between the two galaxy clusters. We performed simulations to show that a volume-filling distribution of weak shocks may reaccelerate a preexisting population of relativistic particles, producing emission at radio wavelengths that illuminates the magnetic ridge.

Lactate, lactate clearance and outcome after cardiac arrest: A post-hoc analysis of the TTM-Trial

BACKGROUND

Admission lactate and lactate clearance are implemented for risk stratification in sepsis and trauma. In out-of-hospital cardiac arrest, results regarding outcome and lactate are conflicting.

METHODS

This is a post-hoc analysis of the Target Temperature Management trial in which 950 unconscious patents after out-of-hospital cardiac arrest were randomized to a temperature intervention of 33°C or 36°C. Serial lactate samples during the first 36 hours were collected. Admission lactate, 12-hour lactate, and the clearance of lactate within 12 hours after admission were analyzed and the association with 30-day mortality assessed.

RESULTS

Samples from 877 patients were analyzed. In univariate logistic regression analysis, the odds ratio for death by day 30 for each mmol/L was 1.12 (1.08-1.16) for admission lactate, P < .01, 1.21 (1.12-1.31) for 12-hour lactate, P < .01, and 1.003 (1.00-1.01) for each percentage point increase in 12-hour lactate clearance, P = .03. Only admission lactate and 12-hour lactate levels remained significant after adjusting for known predictors of outcome. The area under the receiver operating characteristic curve was 0.65 (0.61-0.69), P < .001, 0.61 (0.57-0.65), P < .001, and 0.53 (0.49-0.57), P = .15 for admission lactate, 12-hour lactate, and 12-hour lactate clearance, respectively.

CONCLUSIONS

Admission lactate and 12-hour lactate values were independently associated with 30-day mortality after out-of-hospital cardiac arrest while 12-hour lactate clearance was not. The clinical value of lactate as the sole predictor of outcome after out-of-hospital cardiac arrest is, however, limited.

Estimation of the burden of human placental micro- and nano-vesicles extruded into the maternal blood from 8 to 12 weeks of gestation

BACKGROUND

The human placenta extrudes a variety of extracellular vesicles (EVs) into the maternal blood daily. These vesicles may be crucial to the adaptation of the maternal cardiovascular and immune systems to pregnancy. Quantifying the EVs that are released in early gestation is important to our understanding of how placental EVs may contribute to the regulation of maternal physiology.

METHODS

EVs were isolated from first trimester placental explants and separated into micro- and nano-vesicles by differential centrifugation. The numbers of each type of EVs extruded from each milligram of placentae between gestational weeks 8 and 12 was determined by Nanoparticle Tracking Analysis. The total protein or DNA content of the vesicles was determined by BCA assay or Qubit^® 2.0.

RESULTS

Neither the number of micro- nor nano-EVs/mg explant (n = 49), nor the total protein (n = 19) and DNA content (n = 29) of these EVs changed significantly between 8 and 12 weeks of gestation. When the increasing placental weight with gestation was accounted for, the daily number of placental EVs extruded into the maternal blood increased by more than 100 fold between 8 and 12 weeks (micro-EVs 6.23 X 10¹⁴ and nano-EVs 1.84 X 10¹⁴ at 12 weeks, p = 0.0003).

DISCUSSION

Constant production of micro- and nano-EVs per-milligram placenta, regardless of gestational age, and the increased daily burden of EVs across gestational age indicate these EVs have the potential to regulate maternal physiology from early pregnancy. Since total EV protein content, like EV numbers was, constant, this is a potentially reliable surrogate for quantifying EVs.

Late stillbirth post mortem examination in New Zealand: Maternal decision-making

BACKGROUND

For parents who experience stillbirth, knowing the cause of their baby's death is important. A post mortem examination is the gold standard investigation, but little is known about what may influence parents' decisions to accept or decline.

AIM

We aimed to identify factors influencing maternal decision-making about post mortem examination after late stillbirth.

METHODS

In the New Zealand Multicentre Stillbirth Study, 169 women with singleton pregnancies, no known abnormality at recruitment, and late stillbirth (≥28weeks gestation), from seven health regions were interviewed within six weeks of birth. The purpose of this paper was to explore factors related to post mortem examination decision-making and the reasons for declining. We asked women if they would make the same decision again.

RESULTS

Maternal decision to decline a post mortem (70/169, 41.4%) was more common among women of Māori (adjusted odds ratio (aOR) 4.99 95% confidence interval (CI) 1.70-14.64) and Pacific (aOR 3.94 95% CI 1.47-10.54) ethnicity compared to European, and parity two or more (aOR 2.95 95% CI 1.14-7.62) compared to primiparous. The main reason for declining was that women 'did not want baby to be cut'. Ten percent (7/70) who declined said they would not make this decision again. No woman who consented regretted her decision.

CONCLUSION

Ethnic differences observed in women's post mortem decision-making should be further explored in future studies. Providing information of the effect of post mortem on the baby's body and the possible emotional benefits of a post mortem may assist women faced with this decision in the future.

An evaluation of the objective quality and perceived usefulness of maternity clinical practice guidelines at a tertiary maternity unit

BACKGROUND

Compliance with maternity clinical practice guidelines developed by National Women's Health has been found to be low at audit.

OBJECTIVE

To explore the reasons for poor compliance with maternity guidelines by evaluating the quality of a sample of National Women's Health guidelines using a validated instrument and assessing local guideline users' perceptions of and attitudes toward guidelines.

DESIGN

Five independent reviewers evaluated the quality of 10 purposively selected guidelines for adherence to the Appraisal of Guidelines Research & Evaluation (AGREE) II instrument standards. A self-administered questionnaire for staff was undertaken regarding views of and barriers to guideline use.

RESULTS

None of the guidelines attained a score over 50% for the following domains: stakeholder involvement, rigour of development, applicability, editorial independence. The highest scoring domain was clarity of presentation (mean 69%). All guidelines scored the minimum possible for editorial independence. Survey respondents had positive attitudes toward guidelines, believed that their use could improve quality of care within the service, and felt that encouragement from senior staff members and peers would encourage their use. Accessibility was the most commonly cited of many barriers identified.

CONCLUSION

The National Women's Health guidelines evaluated in this study cannot be considered to be high quality, and could be improved by reporting on methodology of the development process. Although poor guideline development may contribute to failure of the local maternity guidelines, it appears that accessibility is a major barrier to their use and implementation.

Teaching quality improvement to medical students: over a decade of experience

AIM

To describe how we incorporate experiential quality improvement (QI) learning at the University of Auckland by integrating a clinical audit project into the Year 6 obstetrics and gynaecology clinical attachment.

METHODS

Students gain insight into the relevance of QI while engaged in day-to-day clinical work. Students work with a clinical supervisor to identify an area for potential improvement, set a standard of care, measure current practice, investigate reasons for deviation from the standard and make real-world suggestions to close the gap between best evidence and observed practice.

RESULTS

Since 2004, over 1,250 projects have been completed, and two journal articles published. Many of the student projects result in actual improvements to clinical processes of care, and lead to strengthening of academic and service provider learning networks and partnerships.

CONCLUSIONS

Performing a hands-on project within the constraints and context of a busy women's health service is a feasible and effective method of teaching QI. Medical schools have an integral role to play in ensuring future healthcare professionals are equipped with QI knowledge, skills and attitudes. Experiential QI learning enhances clinical teaching and training, and is important in preparing future clinicians to incorporate QI into their daily practice.

An unexpected complication following uterine artery embolisation

A 35-year-old nulliparous woman underwent uterine artery embolisation (UAE) for heavy menstrual bleeding and anaemia due to fibroids, refractive to medical and surgical treatment.Bilateral UAE was performed after cephazolin prophylaxis and analgesia. Postoperatively, pain and abdominal bloating were prominent. Symptoms were initially treated as postembolisation syndrome, and analgesia was escalated. By the third day, pain was worsening and the woman developed marked tachypnoea and tachycardia, with raised inflammatory markers and lactate. An abdominal X-ray and CT showed dilated colon. A colonoscopy demonstrated severe mucosal ulceration down to the muscular layer.A subtotal colectomy and end ileostomy formation was performed with intraoperative findings of toxic megacolon with near perforation. The cause of the toxic megacolon, in the absence of previous bowel pathology, was attributed to pseudomembranous colitis as a consequence of single dose prophylactic antibiotic.

Chemoradiotherapy for squamous cell anal carcinoma: a review of prognostic factors

AIM

Previous literature has sought prognostic factors for the survival of anal cancer patients. The present study aimed to determine prognostic factors for local disease recurrence, distant metastasis and survival for patients treated with radical chemoradiotherapy (CRT) at the Rosemere Cancer Centre, Preston, UK.

METHOD

Patients treated with CRT for nonmetastatic squamous cell anal cancer between September 2000 and January 2013 were studied. Kaplan-Meier and Cox regression analysis assessed the prognostic value of age, sex, tumour size, the proportion of the anal canal circumference involved (ACCI), nodal disease, tumour location and pretreatment haemoglobin.

RESULTS

One hundred and 48 patients with a mean age of 63 years were studied, of whom 15% suffered local disease recurrence and 10% developed distant metastasis. The 5-year overall and cancer-specific survival rates were 84% and 86%, respectively. Predictors of local recurrence were tumour size >5 cm and over two-thirds ACCI (P < 0.01). Predictors of distant metastasis and poor survival were tumour size >5 cm (P < 0.01), node positive disease on imaging (P < 0.05), over two-thirds ACCI (P < 0.01) and a pretreatment haemoglobin level below 130 g/l (P < 0.05). Multivariate analysis found large tumour size to be the most significant factor for local recurrence (P = 0.002) and survival (P = 0.02) whilst over two-thirds ACCI was most predictive of distant metastasis (P < 0.001). Age, gender, palpable lymph nodes and tumour location were not of prognostic value for local disease recurrence, distant metastasis or survival.

CONCLUSION

Tumour size, nodal disease, over two-thirds ACCI and low pretreatment haemoglobin confer poorer prognostic and survival outcomes. Use of intensity-modulated radiation therapy may allow greater radiation doses to be given for locally advanced tumours, thus improving local control and survival and reducing morbidity.

New methods to constrain the radio transient rate: results from a survey of four fields with LOFAR

We report on the results of a search for radio transients between 115 and 190 MHz with the LOw-Frequency ARray (LOFAR). Four fields have been monitored with cadences between 15 min and several months. A total of 151 images were obtained, giving a total survey area of 2275 deg². We analysed our data using standard LOFAR tools and searched for radio transients using the LOFAR Transients Pipeline. No credible radio transient candidate has been detected; however, we are able to set upper limits on the surface density of radio transient sources at low radio frequencies. We also show that low-frequency radio surveys are more sensitive to steep-spectrum coherent transient sources than GHz radio surveys. We used two new statistical methods to determine the upper limits on the transient surface density. One is free of assumptions on the flux distribution of the sources, while the other assumes a power-law distribution in flux and sets more stringent constraints on the transient surface density. Both of these methods provide better constraints than the approach used in previous works. The best value for the upper limit we can set for the transient surface density, using the method assuming a power-law flux distribution, is 1.3 × 10^-3 deg^-2 for transients brighter than 0.3 Jy with a time-scale of 15 min, at a frequency of 150 MHz. We also calculated for the first time upper limits for the transient surface density for transients of different time-scales. We find that the results can differ by orders of magnitude from previously reported, simplified estimates.

Body Mass Index Is Positively Associated with Endometrial Cancer in Chinese Women, Especially Prior to Menopause

Objective: Obesity is a well-known risk factor for developing endometrial cancer. However, the incidence and survival rate of endometrial cancer are associated with ethnicity and geographical area. In addition, whether menopausal status is associated with developing endometrial cancer in obese women and whether obesity is associated with subtypes of endometrial cancer have not been fully investigated. Here, we investigated the effect of BMI on developing endometrial cancer in Chinese women taking into account menopausal status and cancer subtypes.

Methods: Data on 1,127 women with endometrial cancer including body mass index (BMI), age at diagnosis, parity, menopausal status and cancer subtype were collected from the largest obstetrics & gynaecology hospital in China and analysed.

Results: After adjusting for age and parity, the odds for developing endometrial cancer in overweight or obese perimenopausal women was significantly higher than that in women with normal weight (OR=2.6 with 95%CI:1.9-3.5, and OR=3.5 with 95%CI: 2.2-5.4, respectively). The odds of developing endometrial cancer in overweight postmenopausal women were significantly higher than that in women who were normal weight (OR=2.4 with 95%CI: 1.8-3.1), however this was not the case for obese postmenopausal women. We further found that BMI, menopausal status, age and parity were not associated with subtypes of endometrial cancer.

Conclusion: Our data demonstrate that obesity is positively associated with the incidence of developing endometrial cancer in Chinese women, with more significant effects in perimenopausal women.

Prevention of neonatal early onset GBS sepsis: A clear protocol is better than none--or several

Revised New Zealand consensus guidelines on the prevention of early-onset group B streptococcus sepsis in the newborn are presented in this issue of the Journal. We provide some context for these recommendations and discuss issues considered by the multidisciplinary group in formulating the guidelines.

The prevention of early-onset neonatal group B streptococcus infection: New Zealand Consensus Guidelines 2014

AIMS

Group B streptococcal (GBS) disease is the leading cause of early-onset neonatal sepsis in New Zealand. Disease follows vertical transmission of GBS from the mother, which can largely be prevented by intravenous intrapartum antibiotics. A 2004 New Zealand guideline recommended using clinical risk factors to identify mothers who would qualify for intrapartum antibiotics. An expert multidisciplinary group met to reconsider these guidelines in the light of a two year survey of the incidence of early onset GBS neonatal sepsis.

METHODS

Representatives from the New Zealand College of Midwives, the Fetus and Newborn Committee of the Paediatric Society of New Zealand, the Royal New Zealand College of General Practitioners, the New Zealand Committee of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists, the New Zealand sub-Committee of the Australasian Society of Infectious Diseases, and the Canterbury Home Birth Association met to review the literature and the most recent New Zealand data.

RESULTS

The multidisciplinary group noted that the estimated incidence of early-onset GBS sepsis had halved over a 10-year period to be 0.26 per 1,000 live births in 2009-11 and that there were missed opportunities for preventing GBS infection. Consensus was reached that adoption of a national guideline on prevention and management of early onset GBS neonatal sepsis by all practitioners and District Health Boards would have the greatest potential to further reduce the incidence.

CONCLUSION

A risk-based GBS prevention strategy continues to be recommended as being the most clinically and cost effective for the New Zealand context. Universal routine antenatal GBS screening is not recommended.

Chlamydia trachomatis screening in pregnancy in New Zealand: translation of national guidelines into practice

INTRODUCTION: Chlamydia trachomatis (C. trachomatis) is a common sexually transmitted infection (STI), and routine antenatal screening to reduce the risk of vertical transmission is recommended in New Zealand (NZ). AIM: To determine the proportion of pregnant women who have been screened for C. trachomatis in selected hospitals since the 2008 NZ Ministry of Health Chlamydia Management Guidelines were published, and to examine variation by age and ethnicity. METHODS: Clinical audits were undertaken at four NZ hospitals, using electronic databases to determine if C. trachomatis screening had occurred. RESULTS: Only 24%, 31%, 35% and 61% of pregnant women were screened in Tauranga (2010), Auckland (2013), Waikato (2013) and Middlemore (2011) hospitals, respectively. DISCUSSION: Despite increases in the proportion of pregnant women screened in Auckland and Middlemore compared to pre-2008, and higher proportions of young women and Maori women screened, overall antenatal screening for C. trachomatis remains suboptimal. Several strategies are presented to support universal screening in pregnancy, as recommended by the NZ Ministry of Health. KEYWORDS: Chlamydia trachomatis; mass screening; medical audit; pregnancy

Assessment for possible healthcare-associated transmission of a new variant influenza virus--Pennsylvania, August 2011

In August 2011, one of the earliest cases of influenza A(H3N2) variant [A(H3N2)v] virus infection was hospitalized with severe illness. To investigate the potential for healthcare-associated transmission of influenza A(H3N2)v, we evaluated both healthcare providers and patient contacts of the case. We found that healthcare-associated transmission was unlikely.

MESAFace, a graphical interface to analyze the MESA output

MESA (Modules for Experiments in Stellar Astrophysics) has become very popular among astrophysicists as a powerful and reliable code to simulate stellar evolution. Analyzing the output data thoroughly may, however, present some challenges and be rather time-consuming. Here we describe MESAFace, a graphical and dynamical interface which provides an intuitive, efficient and quick way to analyze the MESA output.

NATURE OF PROBLEM

Find a way to quickly and thoroughly analyze the output of a MESA run, including all the profiles, and have an efficient method to produce graphical representations of the data.

SOLUTION METHOD

We created two scripts (to be run consecutively). The first one downloads all the data from a MESA run and organizes the profiles in order of age. All the files are saved as tables or arrays of tables which can then be accessed very quickly by Mathematica. The second script uses the Manipulate function to create a graphical interface which allows the user to choose what to plot from a set of menus and buttons. The information shown is updated in real time. The user can access very quickly all the data from the run under examination and visualize it with plots and tables.

UNUSUAL FEATURES

Moving the slides in certain regions may cause an error message. This happens when Mathematica is asked to read nonexistent data. The error message, however, disappears when the slides are moved back. This issue does not preclude the good functioning of the interface.

ADDITIONAL COMMENTS

The program uses the dynamical capabilities of Mathematica. When the program is opened, Mathematica prompts the user to "Enable Dynamics". It is necessary to accept before proceeding.

RUNNING TIME

Depends on the size of the data downloaded, on where the data are stored (hard-drive or web), and on the speed of the computer or network connection. In general, downloading the data may take from a minute to several minutes. Loading directly from the web is slower. For example, downloading a 200MB data folder (a total of 102 files) with a dual-core Intel laptop, P8700, 2 GB of RAM, at 2.53 GHz took about a minute from the hard-drive and about 23 minutes from the web (with a basic home wireless connection).

A psychotherapy program for soldiers dependents: The effect on recall rates. “They are not going for three weeks and the fighting has already begun!”

Introduction

Deployment to conflict areas poses problems for service families. These stressors pose a high cost from increased rates of marital/family break-up and the impact on operational effectiveness, through early recall from combat zones. Soldiers look forward to a mission whilst partners are more ambivalent. The time before deployment is hard on those who stay behind, who experience high levels of anxiety. Those about to be deployed feel guilty, and have to manage their own anxieties about what the mission will bring - hard work, excitement and danger. Most do not talk about this to their partners, who in turn have to manage their own inner turmoil and worst case ‘fantasies’.

Aims

The project grew from concerns about the welfare of families of deployed army personnel.

Objectives

The project aimed to help them develop a greater capacity to manage, contain and function with these worries. The program provided psychodynamic psychoanalytic practices to a previously neglected group that was not wholly army, but is essential to its well-being.

Methods

The program gave the families a greater understanding of the emotional difficulties faced by their partners before, during and after deployment and lessened the stress in their relationships; strengthening their own and their partners’ sense of self, resilience, and the marital bond.

Results

Usually 3–5% of a unit would be recalled from combat operations, over the duration of a tour, this was reduced to 1%.

Conclusion

A psychotherapy programme for the families of soldiers reduces attrition rates.
