RESUMO
OBJECTIVE: To clarify the relationships of 3 definitions of severity of bronchopulmonary dysplasia (BPD) with adverse neurodevelopmental and respiratory outcomes at early school-age. STUDY DESIGN: Participants comprised 218 consecutive survivors to 7-8 years of age born either <28 weeks' gestation or weighing <1000 g in Victoria, Australia, in 2005. BPD was classified as none, grade 1 (mild), grade 2 (moderate), or grade 3 (severe), using 2 commonly accepted definitions: 1) Jobe2001, and 2) Higgins2018, and our own 3) Victorian Infant Collaborative Study (VICS) 2005, adapted from Jensen2019. Outcomes included major neurodevelopmental disability, low IQ and academic achievement, poor motor function, and poor respiratory function as assessed by spirometry. Outcomes for children with each grade of BPD were compared with children with no BPD. RESULTS: Of the 218 survivors, 132 (61%) had BPD on Jobe2001 criteria, and 113 (52%) had BPD on both Higgins2018 and VICS2005 criteria. Grade 1 on any criteria was not associated with any adverse neurodevelopmental outcomes. Grade 1 on both Higgins2018 and VICS2005 was associated with reduced spirometry, grade 2 on both Higgins2018 and VICS2005, and grade 3 on all criteria were associated with increased risk for both adverse neurodevelopmental and respiratory outcomes. CONCLUSIONS: Compared with no BPD, receiving additional oxygen up to 29% but no positive pressure support at 36 weeks' postmenstrual age increased the risk of abnormal respiratory function but not adverse neurodevelopment. Receiving ≥30% oxygen or any positive pressure support at 36 weeks increased the risk of both adverse outcomes.

Objectives: To determine the prevalence of frailty among community-dwelling older adults in regional Victoria, Australia. Methods: Frailty status of 376 participants from the Crossroads II cross-sectional study was assessed by selected markers of frailty. The selected variables were psychometrically tested. Associations between frailty and socio-demographic, environmental and health factors were analysed using chi-square, ANOVA and binary logistic regression (BLR). Results: Estimated prevalence of frailty was 39.4%. BLR indicated that frailty decreased with higher educational attainment, (OR = .23; 95% CI: .10-.51) increased for divorced/separated participants (OR = 2.68; 95% CI: 1.29-5.56) and when having three (OR = 3.27; 95% CI: 1.07-9.98), four (OR = 7.20; 95% CI: 2.22-23.31) or five or more chronic conditions (OR = 9.18; 95% CI: 2.83-29.72). Discussion: Frailty in this Australian regional community-dwelling sample was higher than other studies conducted in urban areas of Australia. Present results highlight the importance of exploring the multidimensionality of the frailty construct to have a better understanding which factors are associated with the development of this syndrome.

OBJECTIVE: Identifying and describing components of existent governmental reporting systems of NO aiming at informing the design of the implementation of NO reporting systems in countries where they were not fully established. DESIGN: A systematic search was carried out on PubMed, Embase, and the Latin American and Caribbean Health Sciences Literature database. We included studies published from January 2007 to June 2019 describing NO governmental reporting systems. Additionally, we included studies from the list of references in the identified papers, to gather more information about NO reporting systems. We also reviewed documents published in the governmental health department's Web sites, such as outbreak management guidelines and surveillance protocols, provided they were cited in the papers. RESULTS: NO reporting systems were reported in France (Alsace Region), Germany, Norway, United Kingdom, United States (New York State; New York City), Australia (Victoria State), Sweden (Skane Region), Ireland, Scotland (Lothian Region), and Canada (Winnipeg; Ontario). These systems vary according to the type of targeted NO event, such as gastroenteritis, influenza-like illness, invasive group A streptococcal disease or all-health care-acquired infection NO. Germany, Norway, New York City, New York State, Ireland, Winnipeg, and Ontario have established a mandatory reporting for NO. CONCLUSIONS: There is high variability among countries regarding governmental NO reporting systems. This may hinder opportune inter- and intracountries communication concerning NO of potential international public health relevance.

Introduction: There are few population-sampling studies on the prevalence of syphilis in Brazil. Objectives: We aim to determine the seroprevalence of syphilis and identify factors associated with the infection in adult patients observed at six regional healthcare facilities in Vitória city, state of Espírito Santo, Brazil. Methods: A cross-sectional study was conducted between September 2010 and December 2011. For individuals included in the study, a Venereal Disease Research Laboratory (VDRL) test and two treponemal tests (immunochromatographic and IgG ELISA assays) were performed. Demographic data, history of sexually transmitted infections, and behavioral data were collected. Results: Of the 1,502 subjects included in the study, 47% were men and 53% were women. The mean age was 41.63±14.57 years. The prevalence of syphilis was (0.9%; 95%CI 0.41.3) when a diagnosis of syphilis was considered with VDRL titers equal to or greater than 1:8. However, the prevalence was higher (2.8%) when a positive VDRL test, regardless of the titer, was considered. A multivariate analysis showed a significant association between syphilis and homosexual or bisexual behavior [OR=6.80; 95%CI 1.0046.20], prior history of sexually transmitted infection [OR=16.30; 95%CI 3.6173.41], the presence of a tattoo [OR=6.21; 95%CI 1.49 25.84], and cocaine use [OR=6.80; 95%CI 1.1540.30]. The prevalence of positive treponemal test was 10.4%. Conclusion: The seroprevalence of active syphilis in this population was similar to that observed in other populational studies in Brazil. The high prevalence of positive treponemal tests may be due to the positive serological memory of a cured infection, but the results may also be due to cases of early or late syphilis that were not detected by the VDRL test.
Introdução: Existem poucos estudos em amostras populacionais sobre a prevalência da sífilis no Brasil. Objetivos: Determinar a soroprevalência de sífilis e identificar fatores associados à infecção em pacientes adultos atendidos nas unidades das seis regiões de saúde do Município de Vitória, Estado do Espírito Santo. Métodos: Foi realizado um estudo transversal entre setembro de 2010 e dezembro de 2011. Para os indivíduos incluídos no estudo, foram realizados o teste Venereal Disease Research Laboratory (VDRL) e dois testes treponêmicos (imunocromatográfico e IgG ELISA). Foram coletados dados demográficos, histórico de infecções sexualmente transmissíveis e dados comportamentais. Resultados: Dos 1.502 indivíduos incluídos no estudo, 47% eram homens e 53% eram mulheres. A média de idade foi de 41,63±14,57 anos. A prevalência de sífilis foi de 0,9% (IC95% 0,41,3) quando considerado diagnóstico de sífilis com títulos de VDRL iguais ou superiores a 1:8. Porém, a prevalência foi maior (2,8%) quando considerado VDRL positivo, independente do título. Análise multivariada mostrou associação significativa da sífilis com comportamento homo ou bissexual [OR=6,80; IC95% 1,0046,20], história prévia de infecções sexualmente transmissíveis [OR=16,30; IC95% 3,6173,41], tatuagem [OR=6,21; IC95% 1,4925,84] e uso de cocaína [OR=6,80; IC95% 1,1540,30]. A prevalência de teste treponêmico positivo foi de 10,4%. Conclusão: A soroprevalência de sífilis ativa nesta população foi semelhante à observada em outros estudos populacionais no Brasil. A alta prevalência nos testes treponêmicos positivos pode ser devida a cicatriz sorológica de infecção curada, mas pode também estar associada a casos de sífilis primária ou tardia, que não foram detectados pelo teste de VDRL.

The 2019-2020 summer wildfire event on the east coast of Australia was a series of major wildfires occurring from November 2019 to end of January 2020 across the states of Queensland, New South Wales (NSW), Victoria and South Australia. The wildfires were unprecedent in scope and the extensive character of the wildfires caused smoke pollutants to be transported not only to New Zealand, but also across the Pacific Ocean to South America. At the peak of the wildfires, smoke plumes were injected into the stratosphere at a height of up to 25 km and hence transported across the globe. The meteorological and air quality Weather Research and Forecasting with Chemistry (WRF-Chem) model is used together with the air quality monitoring data collected during the bushfire period and remote sensing data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) satellites to determine the extent of the wildfires, the pollutant transport and their impacts on air quality and health of the exposed population in NSW. The results showed that the WRF-Chem model using Fire Emission Inventory (FINN) from National Center for Atmospheric Research (NCAR) to simulate the dispersion and transport of pollutants from wildfires predicted the daily concentration of PM2.5 having the correlation (R2) and index of agreement (IOA) from 0.6 to 0.75 and 0.61 to 0.86, respectively, when compared with the ground-based data. The impact on health endpoints such as mortality and respiratory and cardiovascular diseases hospitalizations across the modelling domain was then estimated. The estimated health impact on each of the Australian Bureau of Statistics (ABS) census districts (SA4) of New South Wales was calculated based on epidemiological assumptions of the impact function and incidence rate data from the 2016 ABS and NSW Department of Health statistical health records. Summing up all SA4 census district results over NSW, we estimated that there were 247 (CI: 89, 409) premature deaths, 437 (CI: 81, 984) cardiovascular diseases hospitalizations and 1535 (CI: 493, 2087) respiratory diseases hospitalizations in NSW over the period from 1 November 2019 to 8 January 2020. The results are comparable with a previous study based only on observation data, but the results in this study provide much more spatially and temporally detailed data with regard to the health impact from the summer 2019-2020 wildfires.

Much of our current understanding about novel coronavirus disease 2019 (COVID-19) comes from hospitalised patients. However, the spectrum of mild and subclinical disease has implications for population-level screening and control. Forty-nine participants were recruited from a group of 99 adults repatriated from a cruise ship with a high incidence of COVID-19. Respiratory and rectal swabs were tested by polymerase chain reaction (PCR) for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Sera were tested for anti-SARS-CoV-2 antibodies by enzyme-linked immunosorbent assay (ELISA) and microneutralisation assay. Symptoms, viral shedding and antibody response were examined. Forty-five participants (92%) were considered cases based on either positive PCR or positive ELISA for immunoglobulin G. Forty-two percent of cases were asymptomatic. Only 15% of symptomatic cases reported fever. Serial respiratory and rectal swabs were positive for 10% and 5% of participants respectively about 3 weeks after median symptom onset. Cycle threshold values were high (range 31-45). Attempts to isolate live virus were unsuccessful. The presence of symptoms was not associated with demographics, comorbidities or antibody response. In closed settings, incidence of COVID-19 could be almost double that suggested by symptom-based screening. Serology may be useful in diagnosis of mild disease and in aiding public health investigations.

OBJECTIVE: To examine the stability of developmental coordination disorder (DCD) throughout childhood in children born very preterm and term. Further, in the very preterm group, to compare perinatal variables and neurobehavioral outcomes at 13 years of age for children with persisting DCD and those with typical motor development. STUDY DESIGN: Prospective study of 180 very preterm and 73 term-born children assessed at 5, 7, and/or 13 years of age using the Movement Assessment Battery for Children, with scores ≤16th percentile used to classify DCD. Children with cerebral palsy or an IQ of <80 were excluded. RESULTS: Children born very preterm had increased odds for DCD at 5 (OR, 5.53; 95% CI, 2.53-12.0; P < .001), 7 (OR, 3.63; 95% CI, 1.43-9.18; P = .06), and 13 years (OR, 4.34; 95% CI, 1.61-11.7; P = .004) compared with term-born children. The rates of DCD in very preterm children reduced from 47.9% at 5 years of age, to 28.5% at 7 years and 27.8% at 13 years of age (OR per year of age, 0.81; 95% CI, 0.75-0.87; P < .001), but less so for term-born children (15.3%, 10.0%, and 8.5% at 5, 7, and 13-years respectively [OR, 0.91; 95% CI, 0.75-1.09; P = .31]). Within the very preterm group at 13 years of age, there was evidence that children with persisting DCD performed poorer across several cognitive domains compared with children with typical motor development, with differences in the order of 0.5-1.0 SD. CONCLUSIONS: Although the rates of DCD decreased across middle childhood for both groups, the odds for DCD were consistently higher for very preterm children compared with term, with important implications for cognitive functioning in the very preterm group.

BACKGROUND: Hypotension following orthopaedic surgery has been associated with increased morbidity and mortality. Rapid response teams (RRT) review patients on hospital wards with hypotension. AIM: To evaluate the epidemiology of hypotensive RRT activations in adult orthopaedic patients to identify contributing factors and areas for future quality improvement. METHODS: Timing of RRT activations, presumed causes of hypotension and associated treatments were assessed. RESULTS: Among 963 RRT activations in 605 patients over 3 years, the first calls of 226 of 605 patients were due to hypotension, and 213 (94.2%) of 226 had sufficient data for analysis. The median age was 79 (interquartile range 66-87) years; 58 (27.2%) were male, and comorbidities were common. Most (68%) surgery was emergent, and 75.1% received intraoperative vasopressors for hypotension. Most activations occurred within 24 h of surgery, and hypovolaemia, infection and arrhythmias were common presumed causes. Fluid boluses occurred in 173 (81.2%), and the time between surgery and RRT activation was 10 (4.0-26.5) h. in cases where fluid boluses were given, compared with 33 (15.5-61.5) h. where they were not (P < 0.001). Blood transfusion (30, 14.1%) and withholding of medications were also common. Hospital mortality was 8.5% (18), and 13.6% (29) were admitted to critical care at some stage. In-hospital death was associated with older age, functional dependence, arrhythmia and presumed infection. CONCLUSIONS: Hypotension-related RRT calls in orthopaedic patients are common. Future interventional studies might focus on perioperative fluid therapy and vaso-active medications, as well as withholding of anti-hypertensive medications preoperatively.

OBJECTIVES: To assess whether preeclampsia was associated with expiratory airflow at school-age in children born either extremely preterm (<28 weeks of gestation) or extremely low birthweight (ELBW; <1000 g birth weight). STUDY DESIGN: Participants comprised 3 cohorts of children born extremely preterm/ELBW in the state of Victoria, Australia, in 1991-1992, 1997, or 2005. Expiratory airflows were measured at age 8 years, and results converted to z scores. Data were compared between those exposed to preeclampsia with those unexposed to preeclampsia; analyses were then adjusted for confounding perinatal variables. Analyses were repeated within subgroups of extremely preterm only and ELBW only. RESULTS: Respiratory data were available for 544 of 717 (76%) survivors, of whom 95 (17%) had been exposed to preeclampsia. On univariable analysis, those exposed to preeclampsia had better z scores for flows for the forced expired volume in 1 second (zFEV1) (mean difference 0.29, 95% CI 0.04-0.53; P = .022) and zFEV1/forced vital capacity (mean difference 0.33, 95% CI 0.04-0.61; P = .025); the difference persisted for zFEV1 after adjustment for confounding perinatal variables. Analyses confined to those born extremely preterm revealed little evidence for associations between preeclampsia and airflow. In analyses confined to those born ELBW, preeclampsia was associated with better zFEV1, which persisted after adjustment (mean difference 0.33, 95% CI 0.04-0.63; P = .025). CONCLUSIONS: Exposure to maternal preeclampsia was not associated with worse expiratory airflow in children born extremely preterm/ELBW; in fact, some airflows were better.

BACKGROUND: Recovery-oriented practice promotes the strengths and recovery potential of individuals. We aimed to establish whether individuals who access mental health services where staff have received the REFOCUS-PULSAR intervention, an adaptation of the UK's REFOCUS recovery-oriented staff intervention for use in Australia, show increased recovery compared with people using non-intervention services. METHODS: We did a pragmatic, two-step, stepped-wedge, randomised controlled trial at 18 sites grouped into 14 clusters across public mental health services and mental health community support services in Victoria, Australia. Eligible staff were working part-time or full-time in a direct service role at one of the 18 sites and had consumers being recruited for this study. Eligible consumers were receiving care from a participating cluster, with contact in the 3 months before data collection; aged 18-75 years; and not imprisoned. Clusters were randomly assigned with a web-based randomisation tool to receive the REFOCUS-PULSAR intervention in either the first year (step one) or second year (step two). Consumers, but not staff, were masked to treatment assignment. The primary outcome was the Questionnaire about the Process of Recovery (QPR), for which cross-sectional data were collected across three timepoints (baseline [T0], year 1 [T1], and year 2 [T2]). The primary analysis was done by intention to treat. This trial is registered with ANZCTR, number ACTRN12614000957695. FINDINGS: 190 staff (111 from public mental health services and 79 from mental health community support services) received the REFOCUS-PULSAR recovery-oriented training intervention. Between Sept 18, 2014, and May 19, 2017, 942 consumers were recruited across the three timepoints (T0: n=301; T1: n=334; T2: n=307). The mean QPR score was 53·6 (SD 16·3) in the control group and 54·4 (16·2) in the intervention group (adjusted difference 3·7, 95% CI 0·5-6·8; p=0·023). The Cohen's d value for the intervention effect was small (d=0·23). INTERPRETATION: The REFOCUS-PULSAR intervention had a small but significant effect on the QPRs of individuals using community mental health services and might be effective in promotion of recovery-oriented practice across sectors.
