SUMMARYWe analysed the serotypes and antibiotic susceptibility of 1560 human and 1505 non-humanSalmonellaisolated in New Zealand (NZ) between 2002 and 2007. The most common serotypes in humans wereSalmonella entericaserovar Typhimurium,S. Enteritidis,S. Brandenburg andS. Infantis. Over the 6-year period human cases due toS. Agona andS. Enteritidis increased and cases due toS. Typhimurium decreased. The most common serotypes from non-human sources wereS. Typhimurium,S. Brandenberg,S. Hindmarsh andS. Infantis, and there were no significant changes over time. More isolates were non-susceptible to streptomycin than to any other antibiotic. Almost all isolates were susceptible to ciprofloxacin and gentamicin. There were significant trends of increasing non-susceptibility to streptomycin and sulfonamides in isolates from human and non-human sources, while ampicillin, tetracycline and multidrug non-susceptibility also increased in human isolates. Despite these increases, rates of antibiotic non-susceptibility inSalmonellain NZ are still lower than in many international settings.

SUMMARYSalmonellosis is an internationally important disease of mammals and birds. Unique epidemics in New Zealand in the recent past include two Salmonella serovars: Salmonella enterica subsp. enterica serovar Typhimurium definitive type (DT) 160 (S. Typhimurium DT160) and S. Brandenburg. Although not a major threat internationally, in New Zealand S. Typhimurium DT160 has been the most common serovar isolated from humans, and continues to cause significant losses in wildlife. We have identified DNA differences between the first New Zealand isolate of S. Typhimurium DT160 and the genome-sequenced strain, S. Typhimurium LT2. All the differences could be accounted for in one cryptic phage ST64B, and one novel P22-like phage, ST160. The majority of the ST160 genome is almost identical to phage SE1 but has two regions not found in SE1 which are identical to the P22-like phage ST64T, suggesting that ST160 evolved from SE1 via two recombination events with ST64T. All of the New Zealand isolates of DT160 were identical indicating the clonal spread of this particular Salmonella. Some overseas isolates of S. Typhimurium DT160 differed from the New Zealand strain and contained SE1 phage rather than ST160. ST160 was also identified in New Zealand isolates of S. Typhimurium DT74 and S. Typhimurium RDNC-April06 and in S. Typhimurium DT160 isolates from the USA. The emergence of S. Typhimurium DT160 as a significant pathogen in New Zealand is postulated to have occurred due to the sensitivity of the Salmonella strains to the ST160 phage when S. Typhimurium DT160 first arrived.

Abstract We examined the effects of different types of specimen labels and tags on pH of different concentrations of ethanol typically used for fluid preservation in natural history collections. Labels were immersed in three different concentrations of ethanol, 96% pure undenatured ethanol (EtOH), 96% EtOH denatured with methyl-ethyl ketone (MEK), and 99.8% pure undenatured EtOH, with or without the presence of insect specimens, and the solutions were evaluated after 26 months for changes over time in pH reading. In general, pH readings of all label trials with 96% and 99.8% ethanol increased over time, except for trials of denatured alcohol, which demonstrated lower pH readings in almost all treatments, regardless of label type. Samples that contained labels with ordinary, nonstandardized, not explicitly acid-free printing paper had higher pH readings compared after the trial. Our observations are a good starting point for further experiments to answer research questions related to chemical interactions with labels in ethanol-preserved specimens, including tissue samples for molecular analyses, which can guide collection staff in their daily work.

Abstract Background The vascular access (VA) is the life-line for children with kidney failure (KT) on hemodialysis (HD). The European Society for Paediatric Nephrology Dialysis Working Group suggested that children requiring HD start with a functioning arteriovenous fistula (AVF) but a tunnelled catheter (TC) can be placed instead where a short period on HD is anticipated before kidney transplantation (KT) (NDT 2019; 34: 1746–1765). Aims To analyze the type of VA used by incident and prevalent KF pediatric patients (pts) treated with HD in Catalonia Method Data from the Catalan Renal Registry of KF pts younger than 18 years of age undergoing kidney replacement therapy (KRT) were examined for a 22-year period. Results The modality of KRT used by incident KF pediatric pts has changed significantly over time: the percentage of children who started KRT through HD decreased progressively from 89.9% during the 1984-1989 period to 38.2% during the 2014-2018 period and, conversely, the percentage of children who started KRT by using pre-emptive KT increased progressively from 5.1% to 42.6% between the same periods (for both comparisons, p<0.001). During 2018, 18 children started KRT (rate: 12.8 per milion of population, pmp) by using pre-emptive KT (n=8, 44.4%), peritoneal dialysis (n=5, 27.8%) or HD (n=5, 27.8%). From 1997 to 2018, 112 KF pediatric pts started KRT by using HD (mean age 9.4±6,0 yr, male 58.9%, glomerular disease 36.8%). Most children started HD through an AVF during the 1997-2001 period (56.5%) but this percentage decreased over time and no children used an AVF for starting HD during the 2012-2018 period. On the contrary, the percentage of children starting HD through a TC increased progressively from 8.7% to 72.2% between the same periods (for both comparisons, p<0.001). No significant changes over time were recorded regarding untunnelled catheter (UC) utilization from 34.8% (1997-2001 period) to 27.8% (2012-2018 period) (p=0.57). Considering two age groups (0-6 vs 7-18 years), VA distribution was the following (%): 23.3 vs 76.7 for UC, 47.2 vs 52.8 for TC and 26.3 vs 73.7 for AVF (p=0.058). Regarding KF presentation, UC was used mainly to initiate HD in crashlanders (53.3%) and AVF was used mainly to start HD in children with steady kidney disease progression (63.2%) (p=0.003). The KRT modality of using prevalent KF pediatric pts has also changed significantly over time: pts on HD decreased from 34.9% (n=15, mean age 13.5 yr) in 1997 to 4.7% (n=5, mean age 11.6 yr) in 2018 and, conversely, pts with a kidney graft increased from 62.8% (n=27, mean age 13.7 yr) to 92.4% (n=98, mean age 11.2 yr) during the same period (for both comparisons, p<0.001). The percentage of children dialyzed through an AVF decreased progressively from 1997 (100%) to 2018 (0%) (p<0.001). All prevalent HD pts were dialyzed through a catheter in 2018. The KT rate increased significantly from 5.4 pmp (n=6) in 1997 to 17.1 pmp (n=24) in 2018 (p=0.007). The median time on HD (months) prior to the first KT decreased progressively from 23.1 during the 1984-1989 period to 6.6 during the 2014-2018 period (p<0.001). Conclusions 1) The VA profile of pediatric population treated with HD in Catalonia has radically changed over time. 2) Since 2012, AVF has practically disappeared as the VA in the incident and prevalent pediatric population on HD. 3) Almost all children treated by HD since 2012 were dialyzed through a catheter due to the short waiting time before receiving a kidney graft. 4) The high KT rate was a determining factor in choosing the AV type in the pediatric population treated with HD in Catalonia.

BackgroundDifferent definitions of chronic fatigue syndrome (CFS) have different psychiatric exclusion criteria and this affects the type and frequency of associated psychiatric morbidity found. The operational criteria for neuraesthenia in ICD–10 vary in this and other respects from the Centers for Disease Control and Prevention (CDC) criteria for CFS. Neuraesthenia and associated psychiatric morbidity in CDC-defined CFS are evaluated.MethodCFS subjects and controls were interviewed with the Schedule for the Clinical Assessment of Neuropsychiatry (SCAN). The computerised scoring program for SCAN (CATEG05) facilitates the assignment of operational definitions according to DSM–III–R and ICD–10. Subjects were re-interviewed with SCAN an average of 11 months later. No specific treatments or interventions were given during this period.ResultsThe majority of subjects fulfilled ICD–10 operational criteria for neuraesthenia and had two and a half times the rate of psychiatric morbidity as the healthy comparison group according to the CATEG05 Index of Definition (ID). Approximately 80% of subjects fulfilled both DSM–III–R and ICD–10 criteria for sleep disorders. There was a significant fall in the number of subjects fulfilling criteria for depression and anxiety disorders and a significant increase in the number of subjects with no diagnosis for DSM–III–R criteria over time. There were no significant changes over time for any diagnosis according to ICD–10 criteria or for overall levels of psychopathology as reflected in CATEG05 ID levels.ConclusionsThe ICD–10 ‘neuraesthenia’ definition identifies almost all subjects with CDC-defined CFS. Fifty per cent of CFS subjects also had depressive or anxiety disorders, some categories of which remit spontaneously over time.

BackgroundThe epidemiology of early-onset neonatal sepsis (EONS) varies over time, and requires regular surveillance.ObjectiveTo analyse data on EONS in Australia and New Zealand.MethodsRetrospective analysis of data collected longitudinally from multiple neonatal units from 2002 to 2012.ResultsOf 386 423 live births, 454 infants had EONS. The incidence rate of EONS was 1.20 per 1000 live births in 2002 and 0.83 in 2012, decreasing by 4% per year (95% CI 1% to 7%, p=0.007). Group B streptococcus (GBS) (37%) and Escherichia coli (25%) were the most prevalent organisms. The early-onset GBS (EOGBS) incidence rate was 0.43/1000 live births, with no evidence of change over time (p=0.3). Of EOGBS-infected babies, 62% were born at term compared with 8% with early-onset E. coli sepsis, p<0.0001. The mortality of E. coli early-onset sepsis (EOS) (25%) was higher than GBS (11%), but this difference in mortality was no longer significant after adjusting for gestation and birth weight. Mortality from EOS fell significantly over the study period (17% per year, 95% CI 10 to 24, p<0.0001).ConclusionsGBS was the most common cause of early sepsis, but the incidence was lower than prior to the introduction of intrapartum antibiotic prophylaxis, and remained steady over time. The mortality of early-onset E. coli sepsis was significantly higher than GBS sepsis, but this may have been because almost all babies with E. coli were born preterm, rather than a difference in virulence.

<p>Exploring the past, and pulling ideas through to the present, to inform the future can make a valuable contribution to nurses and nursing in New Zealand. By gaining some understanding of the attitudes and beliefs nurses held, and how these influenced their responsiveness, we can learn what active responses might help inform our future. Nurses in New Zealand, as individuals and within the profession as a whole, reveal the primacy of the nurse – nurses who have made and can continue to make a difference to the health of the peoples of New Zealand. A hermeneutic process was used to interpret material, from international texts, national texts and public records over four decades, the 1960s to 1990s. This was supplemented and contrasted with material from twelve oral history participants. Analysis of the material led to the emergence of four themes: Nurses’ decision-making: changes over time; An emerging understanding of autonomy and accountability; Nurses as a driving force; and Creating a nursing future. These four themes revealed an overall pattern of attitudes, beliefs and responses of the New Zealand Registered Nurse. The themes surfaced major revelations about the primacy of the nurse in New Zealand, nurses confident in their ability to take the opportunity, seize the moment, and effect change. The contribution this thesis makes to the discipline of nursing is an understanding of how the nurse actively constructs the scope of a professional response to the context. The thesis demonstrates how nurses can learn from the past, that the attitudes and beliefs that underpin our active responses can either move us forward, or retard our progress. As nurses we can also learn that to move forward we need particular attitudes, beliefs and responses, that these are identifiable, and are key factors influencing our future, thus ensuring the continued primacy of the nurse.</p>
