Abstract
AIMS To explore parents' experiences of unsettled babies and medical labels. DESIGN Qualitative systematic review, thematic synthesis and development of a conceptual model. REVIEW METHODS Systematic review and thematic synthesis of primary, qualitative research into parents' experiences of unsettled babies <12 months of age. 'Unsettled' was defined as perception of excessive crying with additional feature(s) such as vomiting, skin or stool problems. The Critical Appraisal Skills Programme (CASP) checklist was used to assess trustworthiness. DATA SOURCES Structured searches completed in CINAHL, Medline, Embase, PsychINFO and CochraneCT on 23 March 2022 and rerun on 14 April 2023. RESULTS Ten eligible studies were included across eight countries contributing data from 103 mothers and 24 fathers. Two analytical themes and eight descriptive themes were developed. Firstly, parents expressed fearing judgement, feeling guilty and out of control as a result of babies' unsettled symptoms and seeking strategies to construct an 'Identity as a "Good Parent"'. This desire for positive parenting identity underpinned the second analytical theme 'Searching for an explanation' which included seeking external (medical) causes for babies' unsettled behaviours. CONCLUSION Parents can become trapped in a cycle of 'searching for an explanation' for their baby's unsettled behaviours, experiencing considerable distress which is exacerbated by feelings of guilt and failure. IMPACT AND IMPLICATIONS FOR PATIENT CARE Insight gained from this review could inform interventions to support parents, reducing inaccurate medicalization. Health visiting teams supporting parents with unsettled baby behaviour could focus on supporting a positive parenting identity by managing expectations, normalizing the continuum of infant behaviours, reducing feelings of guilt or uncertainty and helping parents regain a feeling of control. REPORTING METHOD ENTREQ guidelines were adhered to in the reporting of this review. PATIENT OR PUBLIC CONTRIBUTION Parent input was crucial in the design phase; shaping the language used (e.g., 'unsettled babies') and in the analysis sense-checking findings.

Abstract
AIM To explore parents' perceptions/experiences of help-seeking for unsettled baby behaviours, including views and experiences of obtaining advice from primary healthcare professionals. DESIGN Semi-structured qualitative interviews. METHODS Recruitment occurred via social media, general practice and health visiting teams. Remote semi-structured interviews were conducted with parents of babies. Babies were under 12 months old at time of interview, and parents had perceived unsettled baby behaviours in their first 4 months of life. Interviews were transcribed and data analysed using reflexive thematic analysis. RESULTS Based on interviews with 25 mothers, four main themes were developed. 'The need for answers' highlighted parental uncertainty about what constitutes normal baby behaviour, leading to help-seeking from multiple sources. 'The importance of health professionals' and 'Experiencing health professional support' identified perceptions about limited access, communication, mixed advice and how these influenced parental perception/management of behaviours. 'Foundations to help-seeking' highlighted important roles of social support and online help for valued shared experiences, emotional and practical support. CONCLUSION Health professional access and advice are important to parents, despite the increasing role of online help and importance of social support. More support and improved access to reliable sources of information is needed for parents. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE Findings will inform future research and clinical practice to address parental uncertainties. Qualitative research with front-line health professionals is necessary. IMPACT Findings can inform the development of resources to support professionals/families managing unsettled babies. REPORTING METHOD Standards for Reporting Qualitative Research. PUBLIC INVOLVEMENT A public contributor was involved throughout all stages of the research. Emerging findings were discussed at a parent group. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: Addressing parental uncertainties is important; about what is normal, non-pharmacological approaches and when pharmacological intervention is required. A digital information/self-management intervention may be useful for parents/clinicians.

Abstract
BACKGROUND Female genital cosmetic surgery (FGCS) changes the structure and appearance of healthy external genitalia. We aimed to identify discourses that help explain and rationalise FGCS and to derive from them possibilities for informing clinical education. METHODS We interviewed 16 health professionals and 5 non-health professionals who deal with women's bodies using a study-specific semi-structured interview guide. We analysed transcripts using a three-step iterative process: identifying themes relevant to indications for FGCS, identifying the discourses within which they were positioned, and categorising and theorising discourses. RESULTS We identified discourses that we categorised within four themes: Diversity and the Normal Vulva (diversity was both acknowledged and rejected); Indications for FGCS (Functional, Psychological, Appearance); Ethical Perspectives; and Reasons Women Seek FGCS (Pubic Depilation, Media Representation, Pornography, Advertising Regulations, Social Pressure, Genital Unfamiliarity). CONCLUSIONS Vulvar aesthetics constitute a social construct to which medical practice and opinion contribute and by which they are influenced; education and reform need to occur on all fronts. Resources that not only establish genital diversity but also challenge limited vulvar aesthetics could be developed in consultation with women, healthcare practitioners, mental health specialists, and others with knowledge of social constructs of women's bodies.

Abstract
PURPOSE Coffin-Siris and Nicolaides-Baraitser syndromes are recognizable neurodevelopmental disorders caused by germline variants in BAF complex subunits. The SMARCC2 BAFopathy was recently reported. Herein, we present clinical and molecular data on a large cohort. METHODS Clinical symptoms for 41 novel and 24 previously published affected individuals were analyzed using the Human Phenotype Ontology. For genotype-phenotype correlations, molecular data were standardized and grouped into non-truncating and likely gene-disrupting (LGD) variants. Missense variant protein expression and BAF-subunit interactions were examined using 3D protein modeling, co-immunoprecipitation, and proximity-ligation assays. RESULTS Neurodevelopmental delay with intellectual disability, muscular hypotonia, and behavioral disorders were the major manifestations. Clinical hallmarks of BAFopathies were rare. Clinical presentation differed significantly, with LGD variants being predominantly inherited and associated with mildly reduced or normal cognitive development, whereas non-truncating variants were mostly de novo and presented with severe developmental delay. These distinct manifestations and non-truncating variant clustering in functional domains suggest different pathomechanisms. In vitro testing showed decreased protein expression for N-terminal missense variants similar to LGD. CONCLUSION This study improved SMARCC2 variant classification and identified discernible SMARCC2-associated phenotypes for LGD and non-truncating variants, which were distinct from other BAFopathies. The pathomechanism of most non-truncating variants has yet to be investigated.

Abstract
BACKGROUND Excessive infant crying is common and can have a huge impact on families and well-being. Systematically reviewing qualitative studies on infant crying can provide a greater understanding of parental perceptions and experiences. AIM This study sought to systematically review and thematically synthesize qualitative studies exploring parents/carers' views and experiences of infant crying. DESIGN A systematic review and synthesis of qualitative research. DATA SOURCES Electronic databases MEDLINE, EMBASE, PsycINFO and CINAHL were searched from the earliest date available to January 2022. We selected papers focussing on parents/carers' experiences, views, attitudes and beliefs about infant crying. We excluded papers focussing on health professionals' views and children older than 12 months. REVIEW METHODS Thematic synthesis was followed for the analysis of included studies and quality appraisal was conducted. RESULTS We synthesized 22 papers, reporting data from 376 participants in eight countries. Four analytical themes were developed: (1) Experiences and impact of crying; (2) parental management strategies; (3) the role of the health professional; (4) the role of infant feeding and maternal diet. Our findings suggest that infant crying has a substantial emotional impact on parents/carers that often impacts relationships. Parents/carers reported using a range of soothing techniques and coping strategies but were desperate to find effective treatment or cure. Support was often perceived as lacking. Excessive crying and beliefs about the role of maternal diet on breastmilk were reported to undermine parents' confidence in breastfeeding by making them feel their milk is insufficient or harmful, or through pressure from others to stop breastfeeding. CONCLUSION Parents/carers use a range of strategies to interpret and deal with the challenges of infant crying, but there is a need for more information and support. IMPACT Findings can be used to inform future research and interventions to support families experiencing excessive infant crying.

Abstract
Located in the critical 1p36 microdeletion region, the chromodomain helicase DNA-binding protein 5 (CHD5) gene encodes a subunit of the nucleosome remodeling and deacetylation (NuRD) complex required for neuronal development. Pathogenic variants in six of nine chromodomain (CHD) genes cause autosomal dominant neurodevelopmental disorders, while CHD5-related disorders are still unknown. Thanks to GeneMatcher and international collaborations, we assembled a cohort of 16 unrelated individuals harboring heterozygous CHD5 variants, all identified by exome sequencing. Twelve patients had de novo CHD5 variants, including ten missense and two splice site variants. Three familial cases had nonsense or missense variants segregating with speech delay, learning disabilities, and/or craniosynostosis. One patient carried a frameshift variant of unknown inheritance due to unavailability of the father. The most common clinical features included language deficits (81%), behavioral symptoms (69%), intellectual disability (64%), epilepsy (62%), and motor delay (56%). Epilepsy types were variable, with West syndrome observed in three patients, generalized tonic-clonic seizures in two, and other subtypes observed in one individual each. Our findings suggest that, in line with other CHD-related disorders, heterozygous CHD5 variants are associated with a variable neurodevelopmental syndrome that includes intellectual disability with speech delay, epilepsy, and behavioral problems as main features.

Abstract
AIMS The metabolic syndrome (MetS) is a risk factor for cancer. However, it is not known if the MetS confers a greater cancer risk than the sum of its individual components, which components drive the association, or if the MetS predicts future cancer risk. MATERIALS AND METHODS We linked 20,648 participants from the Australian and New Zealand Diabetes and Cancer Collaboration with complete data on the MetS to national cancer registries and used Cox proportional hazards models to estimate associations of the MetS, the number of positive MetS components, and each of the five MetS components separately with the risk for overall, colorectal, prostate and breast cancer. Hazard ratios (HR) and 95% confidence intervals (95%CI) are reported. We assessed predictive ability of the MetS using Harrell's c-statistic. RESULTS The MetS was inversely associated with prostate cancer (HR 0.85; 95% CI 0.72-0.99). We found no evidence of an association between the MetS overall, colorectal and breast cancers. For those with five positive MetS components the HR was 1.12 (1.02-1.48) and 2.07 (1.26-3.39) for overall, and colorectal cancer, respectively, compared with those with zero positive MetS components. Greater waist circumference (WC) (1.38; 1.13-1.70) and elevated blood pressure (1.29; 1.01-1.64) were associated with colorectal cancer. Elevated WC and triglycerides were (inversely) associated with prostate cancer. MetS models were only poor to moderate discriminators for all cancer outcomes. CONCLUSIONS We show that the MetS is (inversely) associated with prostate cancer, but is not associated with overall, colorectal or breast cancer. Although, persons with five positive components of the MetS are at a 1.2 and 2.1 increased risk for overall and colorectal cancer, respectively, and these associations appear to be driven, largely, by elevated WC and BP. We also demonstrate that the MetS is only a moderate discriminator of cancer risk.

Abstract
Bohring-Opitz syndrome is a rare genetic condition characterized by distinctive facial features, variable microcephaly, hypertrichosis, nevus flammeus, severe myopia, unusual posture (flexion at the elbows with ulnar deviation, and flexion of the wrists and metacarpophalangeal joints), severe intellectual disability, and feeding issues. Nine patients with Bohring-Opitz syndrome have been identified as having a mutation in ASXL1. We report on eight previously unpublished patients with Bohring-Opitz syndrome caused by an apparent or confirmed de novo mutation in ASXL1. Of note, two patients developed bilateral Wilms tumors. Somatic mutations in ASXL1 are associated with myeloid malignancies, and these reports emphasize the need for Wilms tumor screening in patients with ASXL1 mutations. We discuss clinical management with a focus on their feeding issues, cyclic vomiting, respiratory infections, insomnia, and tumor predisposition. Many patients are noted to have distinctive personalities (interactive, happy, and curious) and rapid hair growth; features not previously reported.

Abstract
This study aims at modifying dual-cure composite cements by adding thio-urethane oligomers to improve mechanical properties, especially fracture toughness, and reduce polymerization stress. Thiol-functionalized oligomers were synthesized by combining 1,3-bis(1-isocyanato-1-methylethyl)benzene with trimethylol-tris-3-mercaptopropionate, at 1:2 isocyanate:thiol. Oligomer was added at 0, 10 or 20 wt% to BisGMA-UDMA-TEGDMA (5:3:2, with 25 wt% silanated inorganic fillers) or to one commercial composite cement (Relyx Ultimate, 3M Espe). Near-IR was used to measure methacrylate conversion after photoactivation (700 mW/cm(2) × 60s) and after 72 h. Flexural strength and modulus, toughness, and fracture toughness were evaluated in three-point bending. Polymerization stress was measured with the Bioman. The microtensile bond strength of an indirect composite and a glass ceramic to dentin was also evaluated. Results were analyzed with analysis of variance and Tukey's test (α = 0.05). For BisGMA-UDMA-TEGDMA cements, conversion values were not affected by the addition of thio-urethanes. Flexural strength/modulus increased significantly for both oligomer concentrations, with a 3-fold increase in toughness at 20 wt%. Fracture toughness increased over 2-fold for the thio-urethane modified groups. Contraction stress was reduced by 40% to 50% with the addition of thio-urethanes. The addition of thio-urethane to the commercial cement led to similar flexural strength, toughness, and conversion at 72h compared to the control. Flexural modulus decreased for the 20 wt% group, due to the dilution of the overall filler volume, which also led to decreased stress. However, fracture toughness increased by up to 50%. The microtensile bond strength increased for the experimental composite cement with 20 wt% thio-urethane bonding for both an indirect composite and a glass ceramic. Novel dual-cured composite cements containing thio-urethanes showed increased toughness, fracture toughness and bond strength to dentin while demonstrating reduced contraction stress. All of these benefits are derived without compromising the methacrylate conversion of the resin component. The modification does not require changing the operatory technique.

Abstract
BACKGROUND There is some evidence for a bidirectional association between obesity and depression. However, studies examining weight change and depression are scarce and report inconsistent findings. OBJECTIVE The objective was to investigate the relationship between average annual percentage weight change and depression in mid-aged women. DESIGN This was a prospective cohort study. SUBJECTS A total of 8246 women aged 45-50 years at baseline participating in the Australian Longitudinal Study on Women's Health were surveyed every 3 years over a 12-year period. Information on body mass index and depression was collected at each survey. We used regression models to investigate the effect of weight change predicting depression and vice versa, by calculating odds ratios (ORs) with 95% confidence intervals (CIs). RESULTS Weight gain was associated with an increased risk of prevalence (OR 1.39, 95% CI 1.25-1.56) and incidence (OR 1.30, 95% CI 1.14-1.49) of depression. However, in time-lagged analyses, where weight change between the two preceding surveys was used to predict incidence of depression at the current survey, no statistically significant associations with depression were found. Compared with women without depression, women with prevalent and incident depression had an increased risk of weight gain (OR 1.29, 95% CI 1.19-1.40 and OR 1.20, 95% CI 1.05-1.38, respectively). When incidence of depression was lagged with respect to weight change between the two subsequent surveys, depression remained associated with an increased risk (OR 1.19, 95% CI 1.00-1.41) of gaining weight. CONCLUSION These findings suggest that depression may cause weight gain over the next 3 years, but that weight change (loss or gain) may not lead to depression. Further research at shorter intervals, perhaps 6 monthly or yearly is needed to ascertain whether weight change is an independent predictor of depression in the shorter term.

Abstract
There is increasing interest in the direct and indirect effects of pathogens and parasites on the structure of plant communities. The direct influence of pathogens is seen in cases where pathogens reduce the populations of adult and seedling plants or prevent the recruitment of seeds. Indirect effects occur when epidemic outbreaks or endemic parasites of herbivores lead to reductions in grazing pressure, which temporarily allow plants to escape from the detrimental effects of their herbivores. In both cases, the presence of pathogens can lead to changes in the relative abundance of the species in a plant community, which are discernible for many years after the initial disease outbreak has passed.

Abstract
PyeR (PA4354) is a novel member of the ArsR family of transcriptional regulators and modulates biofilm formation in Pseudomonas aeruginosa. Characterization of this regulator showed that it has negative autoregulatory properties and binds to a palindromic motif conserved among PyeR orthologues. These characteristics are in line with classical ArsR-family regulators, as is the fact that PyeR is part of an operon structure (pyeR-pyeM-xenB). However, PyeR also exhibits some atypical features in comparison with classical members of the ArsR family, as it does not harbour metal-binding motifs and does not appear to be involved in metal perception or resistance. Hence, PyeR belongs to a subgroup of non-classical ArsR-family regulators and is the second ArsR regulator shown to be involved in biofilm formation.

Abstract
BACKGROUND Tobacco smoking and poor mental health are both prevalent and detrimental health problems in young women. The temporal relationship between the two variables is unclear. We investigated the prospective bi-directional relationship between smoking and mental health over 13 years. METHOD Participants were a randomly selected community sample of 10 012 young women with no experience of pregnancy, aged 18-23 years at baseline (1996) from the Australian Longitudinal Study on Women's Health. Follow-up surveys over 13 years were completed in 2000, 2003, 2006 and 2009, allowing for five waves of data. Measures included self-reported smoking and mental health measured by the Mental Health Index from the 36-item short-form health questionnaire and the 10-item Center for Epidemiologic Studies Depression Scale. Sociodemographic control variables included marital status, education level and employment status. RESULTS A strong cross-sectional dose-response relationship between smoking and poor mental health was found at each wave [odds ratio (OR) 1.41, 95% confidence intervals (CI) 1.17-1.70 to OR 2.27, 95% CI 1.82-2.81]. Longitudinal results showed that women who smoked had 1.21 (95% CI 1.06-1.39) to 1.62 (95% CI 1.24-2.11) times higher odds of having poor mental health at subsequent waves. Women with poor mental health had 1.12 (95% CI 1.17-1.20) to 2.11 (95% CI 1.68-2.65) times higher odds of smoking at subsequent waves. These results held after adjusting for mental health history and smoking history and sociodemographic factors. Correlation analysis and structural equation modelling results were consistent in showing that both directions of the relationship were statistically significant. CONCLUSIONS The association between poor mental health and smoking in young women appeared to be bi-directional.

Abstract
AIMS To evaluate the ability of the broad-spectrum lantibiotic, lacticin 3147, to prevent Streptococcus mutans biofilm formation and disrupt existing biofilms. METHODS AND RESULTS Minimum inhibitory concentrations (MIC) and minimum biofilm inhibitory concentrations of purified lacticin 3147 were determined using a microdilution method. Lacticin 3147 effectively inhibited planktonic Strep. mutans, with MIC of 1.9-3.8 μmol l(-1). Time-kill kinetic studies confirmed that lacticin 3147 exhibited bactericidal activity against Strep. mutans at 38 μmol l(-1) (or 10× MIC). The effect of lacticin 3147 on biofilm formation and reduction was also determined. Exposure to 6.3-μmol l(-1) lacticin 3147 (2× MIC) resulted in substantial reductions in Strep. mutans biofilm formation while lacticin 3147 was less effective against 1-day-old biofilms. Culture-based analyses revealed that lacticin 3147 (50 μmol l(-1)) significantly inhibited Streptococcus spp. present in human saliva (P < 0.05) with an approximate 4-log reduction in viability compared with the control. CONCLUSIONS These results indicate that lacticin 3147 may be an effective therapy against Strep. mutans and was shown to substantially attenuate its ability to form a biofilm. SIGNIFICANCE AND IMPACT OF THE STUDY Lacticin 3147 has the potential to be a useful adjunct to traditional oral therapeutic approaches in addition to its use as a bioactive ingredient for food applications.

Abstract
SUMMARY This study explores risk factors for height loss and consequences in terms of health and wellbeing, in older women. Osteoporosis, low body-mass index, being born in Europe and using medications for both sleep and anxiety were risk factors for height loss. Height loss was associated with digestive problems; excessive height loss was also associated with urinary stress-incontinence and a decline in self-rated health. INTRODUCTION Height loss is associated with osteoporosis, but little is known about its consequences. We aimed to examine the risk factors for height loss and the symptoms associated with height loss. METHODS Elderly participants of the Australian Longitudinal Study on Women's Health (aged 70-75 in 1996) who provided data on height at any two consecutive surveys (held in 1996, 1999, 2002, and 2005) were included (N = 9,852). A regression model was fitted with height loss as the outcome and sociodemographics, osteoporosis, and other risk factors as explanatory variables. Symptoms related to postural changes or raised intra-abdominal pressure were analyzed using height loss as an explanatory variable. RESULTS Over 9 years, average height loss per year was -0.12% (95% confidence intervals [95% CI] = -0.13 to -0.12) of height at baseline. Height loss was greater among those with osteoporosis and low body mass index and those taking medications for sleep and anxiety. After adjusting for confounders, symptoms associated with height loss of > or =2% were heartburn/indigestion (odds ratio [OR] = 1.19, 95% CI = 1.01 to 1.40), constipation (OR = 1.18, 95% CI = 1.01 to 1.37), and urinary stress incontinence (OR = 1.20, 95% CI = 1.02 to 1.41). CONCLUSION These findings highlight the importance of monitoring height among the elderly in general practice and targeting associated symptoms.

Abstract
Data from three MONICA centres in Auckland (New Zealand) and Newcastle and Perth (Australia) are used to explore some of the issues involved in comparing event rates and case fatality among MONICA centres. Auckland and Newcastle follow the "hot pursuit" method of identifying and interviewing patients while they are still in hospital. Perth follows the "cold pursuit" method, in which patients are identified by search of computerized hospital records after discharge and all data are abstracted retrospectively from case notes. Fatal cases are identified by the same method in the three centres. The distribution of events by MONICA diagnostic classification varied among centres, with Perth having the highest proportion of definite myocardial infarction events and the lowest proportion of possible myocardial infarction events. These differences appear to be due to the different methods of event ascertainment and data collection, and to variations in post mortem rates between centres. For comparisons among these three centres, the categories of non-fatal definite myocardial infarction and of all coronary heart disease deaths (that is those in the MONICA categories fatal definite myocardial infarction, fatal possible myocardial infarction, and fatal cases with insufficient data) appear to be the most useful.

Abstract
SUMMARY The suitability of alternative sites for non-invasive blood pressure (NIBP) measurement was investigated in 100 awake healthy volunteers. The calf and the ankle were chosen for comparison with the arm, and the results analysed subjected to Bland-Altman analysis. Discomfort was graded using a Visual Analogue Scale. There was a poor agreement between the different sites with respect to systolic blood pressure: the agreement was closer for diastolic and mean measurements. The mean blood pressure calf measurement was on average 4 mmHg (95% limits of agreement -12 to 20), higher than the arm. The ankle was 8 mmHg higher (-8 to 24) than the arm. ANOVA demonstrated a statistically significant difference in the discomfort scores between the sites (p < 0.001). The calf demonstrated the highest discomfort score and the ankle the lowest. We suggest that the ankle should be considered in preference to the calf as an alternative site for NIBP measurement if use of an arm is undesirable or impossible.

Abstract
OBJECTIVES To examine the associations between indicators of socioeconomic position (SEP) and hysterectomy in two Australian and two British cohorts. STUDY POPULATION Women participating in the Australian Longitudinal Study on Women's Health (ALSWH), born 1921-1926 and 1946-1951, and two cohorts of British women, the British Women's Heart and Health Study and the MRC National Survey of Health and Development, born at similar times (1920 to 1939 and 1946, respectively) and surveyed at similar ages to the ALSWH cohorts. METHODS Relative indices of inequality were derived for own and head of household occupational class, educational level attained and age at leaving school. Logistic regression was used to test the associations between these indicators of SEP and self-reported hysterectomy and/or oophorectomy. RESULTS Inverse associations between indicators of SEP and hysterectomy were found in both the Australian and British cohorts of women born in 1946 or later. There was also evidence of an inverse association between education and hysterectomy in the older Australian cohort. However, the associations in this older cohort were weaker than those found in the mid-aged Australian cohort. In the older British cohort, born in the 1920s and 1930s, little evidence of association between SEP in adulthood and hysterectomy was found. CONCLUSIONS These results suggest that inverse associations between indicators of SEP and hysterectomy are stronger in younger than in older cohorts in both Australia and Great Britain. They provide further evidence of the dynamic nature of the association between indicators of SEP and hysterectomy.

Abstract
OBJECTIVES This study reports on the distributions of food and nutrient intakes by socio-demographic factors for a large population sample of mid-aged Australian women participating in the Australian Longitudinal Study on Women's Health. DESIGN This cross-sectional population-based study used the Cancer Council of Victoria food frequency questionnaires to derive estimates of food and nutrient intakes. SETTING Nationwide community-based survey. SUBJECTS A total of 10561 women aged 50-55 y, at the time of the survey in 2001. RESULTS Analysis showed favourable patterns of food intake, with frequent consumption of many foods that are promoted as components of a healthy diet (eg, fresh fruit, leafy green and other vegetables, bread, cereals, milk and meat). Intakes of both foods and nutrients varied significantly across socio-demographic groups, with unmarried women, and women in 'labouring' occupations (eg, cleaner, factory worker, kitchenhand) having poorer nutrient intake. CONCLUSIONS Although many mid-aged women in this sample had generally healthful diets, women in certain socio-demographic groups (particularly unmarried women and those in labouring occupations) had nutrient intakes of concern. As well as helping to address the dearth of current data on dietary intakes in the Australian population, the results highlight the need for continued targeted public health strategies aimed at improving diet of women from the various socio-economic backgrounds.

Abstract
The monitoring of infection control indicators including hospital-acquired infections is an established part of quality maintenance programmes in many health-care facilities. However, surveillance data use can be frustrated by the infrequent nature of many infections. Traditional methods of analysis often provide delayed identification of increasing infection occurrence, placing patients at preventable risk. The application of Shewhart, Cumulative Sum (CUSUM) and Exponentially Weighted Moving Average (EWMA) statistical process control charts to the monitoring of indicator infections allows continuous real-time assessment. The Shewhart chart will detect large changes, while CUSUM and EWMA methods are more suited to recognition of small to moderate sustained change. When used together, Shewhart and EWMA methods are ideal for monitoring bacteraemia and multiresistant organism rates. Shewhart and CUSUM charts are suitable for surgical infection surveillance.

Abstract
Seven Standardbred horses were exercised on a treadmill at speeds (approximately 12 m/s) producing maximal heart rate, hypoxemia, and a mean pulmonary arterial pressure of approximately 75 mmHg. Extravascular lung water was measured by using transients in temperature and electrical impedance of the blood caused by a bolus injection of cold saline solution. Lung water was approximately 3 ml/kg body wt when standing but did not increase significantly with exertion. We conclude that any increase in fluid extravasation from the pulmonary hypertension accumulates in the lung at a level that is less than that detectable by this method. At maximal exertion, the volume of blood measured between the jugular vein and the carotid artery increased by approximately 8 ml/kg, and the actively circulating component of the systemic blood volume increased by approximately 17 ml/kg with respect to corresponding values obtained when walking before exertion. These volume increases, reflecting recruitment and dilatation of capillaries, increase the area for respiratory gas exchange and offset the reduced transit times that would otherwise be imposed by the approximately eightfold increase in cardiac output at maximal exertion.
