A tailored COVID-19 vaccination pathway for children 5-11 years in Victoria, Australia. Vaccine 2023; 41:3436-3445. [PMID: 37120401 PMCID: PMC10106821 DOI: 10.1016/j.vaccine.2023.04.032] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2022] [Revised: 03/09/2023] [Accepted: 04/11/2023] [Indexed: 05/01/2023]
Abstract
BACKGROUND Procedural anxiety was anticipated in children 5-11 years during the COVID-19 vaccine rollout in Victoria, Australia, as children in this age group receive few routine vaccines. Therefore, the Victorian state government designed a tailored, child-friendly vaccine program. This study aimed to assess parental satisfaction with elements of the bespoke vaccination pathway. METHODS The Victorian government and state-run vaccination hubs in Victoria facilitated an online immunisation plan to help parents identify their child's support needs, and utilised experienced paediatric staff and additional supports for children with severe needle distress and/or disability. All parents/guardians of children 5-11 years who received a COVID-19 vaccine in a vaccination hub were sent a 16-item feedback survey via text message. RESULTS Between 9 February and 31 May 2022 there were 9203 responses; 865 children (9.4%) had a first language other than English, 499 (5.4%) had a disability or special needs, and 142 (1.5%) were Aboriginal or Torres Strait Islander. Most parents (94.4%; 8687/9203) rated their satisfaction with the program as very good or excellent. The immunisation plan was used by 13.5% (1244/9203) of respondents, with usage more common for Aboriginal or Torres Strait Islander children (26.1%; 23/88) or families with a first language other than English (23.5%; 42/179). The child-friendly staff (88.5%, 255/288) and themed environment (66.3%, 191/288) were the most valued measures for vaccination. Additional support measures were required by 1.6% (150/9203) of children in the general population and 7.9%, (17/261) of children with a disability and/or special needs. CONCLUSION A tailored COVID-19 vaccination program for children 5-11 years, with additional support for children with severe needle distress and/or disability, had high parental satisfaction. This model could be utilised for COVID-19 vaccination in pre-school children and for routine childhood vaccination programs to provide optimal support to children and their families.

Achieved blood pressure post-acute kidney injury and risk of adverse outcomes after AKI: A prospective parallel cohort study. BMC Nephrol 2021; 22:270.

Abstract
BACKGROUND There has recently been considerable interest in better understanding how blood pressure should be managed after an episode of hospitalized AKI, but there are scant data regarding the associations between blood pressure measured after AKI and subsequent adverse outcomes. We hypothesized that among AKI survivors, higher blood pressure measured three months after hospital discharge would be associated with worse outcomes. We also hypothesized these associations between blood pressure and outcomes would be similar among those who survived non-AKI hospitalizations. METHODS We quantified how systolic blood pressure (SBP) observed three months after hospital discharge was associated with risks of subsequent hospitalized AKI, loss of kidney function, mortality, and heart failure events among 769 patients in the prospective ASSESS-AKI cohort study who had hospitalized AKI. We repeated this analysis among the 769 matched non-AKI ASSESS-AKI enrollees. We then formally tested for AKI interaction in the full cohort of 1538 patients to determine if these associations differed among those who did and did not experience AKI during the index hospitalization. RESULTS Among 769 patients with AKI, 42 % had subsequent AKI, 13 % had loss of kidney function, 27 % died, and 18 % had heart failure events. SBP 3 months post-hospitalization did not have a stepwise association with the risk of subsequent AKI, loss of kidney function, mortality, or heart failure events. Among the 769 without AKI, there was also no stepwise association with these risks. In formal interaction testing using the full cohort of 1538 patients, hospitalized AKI did not modify the association between post-discharge SBP and subsequent risks of adverse clinical outcomes. CONCLUSIONS Contrary to our first hypothesis, we did not observe that higher stepwise blood pressure measured three months after hospital discharge with AKI was associated with worse outcomes. Our data were consistent with our second hypothesis that the association between blood pressure measured three months after hospital discharge and outcomes among AKI survivors is similar to that observed among those who survived non-AKI hospitalizations.

Abstract
BACKGROUND Acute kidney injury (AKI) and obesity are independent risk factors for chronic kidney disease (CKD). This study aimed to determine if obesity modifies risk for CKD outcomes after AKI. METHODS This prospective multisite cohort study followed adult survivors after hospitalization, with or without AKI. The primary outcome was a combined CKD event of incident CKD, progression of CKD and kidney failure, examined using time-to-event Cox proportional hazards models, adjusted for diabetes status, age, pre-existing CKD, cardiovascular disease status and intensive care unit admission, and stratified by study center. Body mass index (BMI) was added as an interaction term to examine effect modification by body size. RESULTS The cohort included 769 participants with AKI and 769 matched controls. After median follow-up of 4.3 years, among AKI survivors, the rate of the combined CKD outcome was 84.7 per1000-person-years with BMI ≥30 kg/m2, 56.4 per 1000-person-years with BMI 25-29.9 kg/m2, and 72.6 per 1000-person-years with BMI 20-24.9 kg/m2. AKI was associated with a higher risk of combined CKD outcomes; adjusted-HR 2.43 (95%CI 1.87-3.16), with no evidence that this was modified by BMI (p for interaction = 0.3). After adjustment for competing risk of death, AKI remained associated with a higher risk of the combined CKD outcome (subdistribution-HR 2.27, 95%CI 1.76-2.92) and similarly, there was no detectable effect of BMI modifying this risk. CONCLUSIONS In this post-hospitalization cohort, we found no evidence for obesity modifying the association between AKI and development or progression of CKD.

Abstract
In this work, we hypothesized that shifts in the food microbiome can be used as an indicator of unexpected contaminants or environmental changes. To test this hypothesis, we sequenced the total RNA of 31 high protein powder (HPP) samples of poultry meal pet food ingredients. We developed a microbiome analysis pipeline employing a key eukaryotic matrix filtering step that improved microbe detection specificity to >99.96% during in silico validation. The pipeline identified 119 microbial genera per HPP sample on average with 65 genera present in all samples. The most abundant of these were Bacteroides, Clostridium, Lactococcus, Aeromonas, and Citrobacter. We also observed shifts in the microbial community corresponding to ingredient composition differences. When comparing culture-based results for Salmonella with total RNA sequencing, we found that Salmonella growth did not correlate with multiple sequence analyses. We conclude that microbiome sequencing is useful to characterize complex food microbial communities, while additional work is required for predicting specific species' viability from total RNA sequencing.

Phylogenetic and Biogeographic Patterns of Vibrio parahaemolyticus Strains from North America Inferred from Whole-Genome Sequence Data. Appl Environ Microbiol 2021; 87:e01403-20.

Abstract
Vibrio parahaemolyticus is the most common cause of seafood-borne illness reported in the United States. The draft genomes of 132 North American clinical and oyster V. parahaemolyticus isolates were sequenced to investigate their phylogenetic and biogeographic relationships. The majority of oyster isolate sequence types (STs) were from a single harvest location; however, four were identified from multiple locations. There was population structure along the Gulf and Atlantic Coasts of North America, with what seemed to be a hub of genetic variability along the Gulf Coast, with some of the same STs occurring along the Atlantic Coast and one shared between the coastal waters of the Gulf and those of Washington State. Phylogenetic analyses found nine well-supported clades. Two clades were composed of isolates from both clinical and oyster sources. Four were composed of isolates entirely from clinical sources, and three were entirely from oyster sources. Each single-source clade consisted of one ST. Some human isolates lack tdh, trh, and some type III secretion system (T3SS) genes, which are established virulence genes of V. parahaemolyticus Thus, these genes are not essential for pathogenicity. However, isolates in the monophyletic groups from clinical sources were enriched in several categories of genes compared to those from monophyletic groups of oyster isolates. These functional categories include cell signaling, transport, and metabolism. The identification of genes in these functional categories provides a basis for future in-depth pathogenicity investigations of V. parahaemolyticusIMPORTANCEVibrio parahaemolyticus is the most common cause of seafood-borne illness reported in the United States and is frequently associated with shellfish consumption. This study contributes to our knowledge of the biogeography and functional genomics of this species around North America. STs shared between the Gulf Coast and the Atlantic seaboard as well as Pacific waters suggest possible transport via oceanic currents or large shipping vessels. STs frequently isolated from humans but rarely, if ever, isolated from the environment are likely more competitive in the human gut than other STs. This could be due to additional functional capabilities in areas such as cell signaling, transport, and metabolism, which may give these isolates an advantage in novel nutrient-replete environments such as the human gut.

Abstract
BACKGROUND AND OBJECTIVES The risk-benefit ratio of angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy after AKI may be altered due to concerns regarding recurrent AKI. We evaluated, in a prospective cohort, the association between use (versus nonuse) of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers and the subsequent risk of AKI and other adverse outcomes after hospitalizations with and without AKI. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We studied 1538 patients recently discharged from the hospital who enrolled in the multicenter, prospective ASSESS-AKI study, with approximately half of patients experiencing AKI during the index hospitalization. All participants were seen at a baseline visit 3 months after their index hospitalization and were categorized at that time on whether they were using angiotensin-converting enzyme inhibitors/angiotensin receptor blockers or not. We used multivariable Cox regression, adjusting for demographics, comorbidities, eGFR, urine protein-creatinine ratio, and use of other medications, to examine the association between angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use and subsequent risks of AKI, death, kidney disease progression, and adjudicated heart-failure events. RESULTS The use of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers was 50% (386/769) among those with AKI during the index hospitalization and 47% (362/769) among those without. Among those with AKI during the index hospitalization, angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use was not associated with a higher risk of recurrent hospitalized AKI (adjusted hazard ratio, 0.88; 95% confidence interval, 0.69 to 1.13). Associations between angiotensin-converting enzyme inhibitor/angiotensin receptor blocker use and death, kidney disease progression, and adjudicated heart-failure events appeared similar in study participants who did and did not experience AKI during the index hospitalization (all interaction P values >0.05). CONCLUSIONS The risk-benefit ratio of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker therapy after hospital discharge appears to be similar regardless of whether AKI occurred during the hospitalization.

Abstract
BACKGROUND Studies have described Mesoamerican nephropathy among agricultural workers of El Salvador and northwestern Nicaragua. Data on prevalence and risk factors for CKD beyond agricultural workers and in other regions in Nicaragua are sparse. METHODS We recruited participants from 32 randomly selected communities in the Department of Rivas's ten municipalities in two phases. In phase 1, we screened participants using a field-based capillary creatinine measuring system and collected self-reported information on lifestyle and occupational, exposure, and health histories. Two years later, in phase 2, we enrolled 222 new participants, performing serum creatinine testing in these participants and confirmatory serum creatinine testing in phase 1 participants. RESULTS We enrolled 1242 of 1397 adults (89%) living in 533 households (median age 41 years; 43% male). We confirmed CKD (eGFR<60 ml/min per 1.73 m2) in 53 of 1227 (4.3%) evaluable participants. In multivariable testing, risk factors for prevalent CKD included age (odds ratio [OR], 1.92; 95% confidence interval [95% CI], 1.89 to 1.96) and self-reported history of hypertension (OR, 1.95; 95% CI, 1.04 to 3.64), diabetes (OR, 2.88; 95% CI, 1.40 to 5.93), or current or past work in the sugarcane industry (OR 2.92; 95% CI, 1.36 to 6.27). CONCLUSIONS Adjusted CKD prevalence was about 5% with repeat confirmatory testing in southwest Nicaragua, lower than in the northwest region. Risk factors included diabetes, hypertension, and current or prior work in the sugarcane industry but not in other forms of agricultural work. Formal CKD surveillance programs in Nicaragua are needed to assess the overall burden of CKD nationally, with a focus on agricultural workers.

Abstract
Trauma exposure is highly prevalent among children globally, and is associated with elevated rates of PTSD. The goal of this study was to systematically evaluate the effects of multiple informants and multiple screening measures on the identification of specific PTSD symptoms and rates of PTSD diagnoses. Participants in this study included 350 maltreated children from two cohorts, one recruited from Connecticut (n = 130), and the other from Vermont (n = 220). Both cohorts completed the Screen for Child Anxiety-Related Emotional Disorders (SCARED) before a PTSD self-report measure. The KSADS psychiatric interview was also completed with the Connecticut cohort, with best-estimate ratings generated using parent and child interview, child self-report, and teacher questionnaire data. In addition to the SCARED and PTSD self-report scale, parents of the Vermont cohort completed the Child Behavioural Checklist. Significant differences emerged between parent and child report of sleep, nightmares, concentration, and irritability problems, suggesting the need for multiple informants in PTSD screening. Children also under-reported nightmares when asked in the context of a trauma-specific screening tool. As child trauma is associated with a broad range of psychiatric sequelae, comprehensive assessment using both general symptomatology and trauma-specific measures is recommended, since children often shut down when completing trauma measures.

Abstract
IMPORTANCE Among patients who had acute kidney injury (AKI) during hospitalization, there is a need to improve risk prediction such that those at highest risk for subsequent loss of kidney function are identified for appropriate follow-up. OBJECTIVE To evaluate the association of post-AKI proteinuria with increased risk of future loss of renal function. DESIGN, SETTING, AND PARTICIPANTS The Assessment, Serial Evaluation, and Subsequent Sequelae in Acute Kidney Injury (ASSESS-AKI) Study was a multicenter prospective cohort study including 4 clinical centers in North America included 1538 patients enrolled 3 months after hospital discharge between December 2009 and February 2015. EXPOSURES Urine albumin-to-creatinine ratio (ACR) quantified 3 months after hospital discharge. MAIN OUTCOMES AND MEASURES Kidney disease progression defined as halving of estimated glomerular filtration rate (eGFR) or end-stage renal disease. RESULTS Of the 1538 participants, 769 (50%) had AKI durring hospitalization. The baseline study visit took place at a mean (SD) 91 (23) days after discharge. The mean (SD) age was 65 (13) years; the median eGFR was 68 mL/min/1.73 m2; and the median urine ACR was 15 mg/g. Overall, 547 (37%) study participants were women and 195 (13%) were black. After a median follow-up of 4.7 years, 138 (9%) participants had kidney disease progression. Higher post-AKI urine ACR level was associated with increased risk of kidney disease progression (hazard ratio [HR], 1.53 for each doubling; 95% CI, 1.45-1.62), and urine ACR measurement was a strong discriminator for future kidney disease progression (C statistic, 0.82). The performance of urine ACR was stronger in patients who had had AKI than in those who had not (C statistic, 0.70). A comprehensive model of clinical risk factors (eGFR, blood pressure, and demographics) including ACR provided better discrimination for predicting kidney disease progression after hospital discharge among those who had had AKI (C statistic, 0.85) vs those who had not (C statistic, 0.76). In the entire matched cohort, after taking into account urine ACR, eGFR, demographics, and traditional chronic kidney risk factors determined 3 months after discharge, AKI (HR, 1.46; 95% CI, 0.51-4.13 for AKI vs non-AKI) or severity of AKI (HR, 1.54; 95% CI, 0.50-4.72 for AKI stage 1 vs non-AKI; HR, 0.56; 95% CI, 0.07-4.84 for AKI stage 2 vs non-AKI; HR, 2.24; 95% CI, 0.33-15.29 for AKI stage 3 vs non-AKI) was not independently associated with more rapid kidney disease progression. CONCLUSIONS AND RELEVANCE Proteinuria level is a valuable risk-stratification tool in the post-AKI period. These results suggest there should be more widespread and routine quantification of proteinuria after hospitalized AKI.

Strategies to Reduce Acute Kidney Injury and Improve Clinical Outcomes Following Percutaneous Coronary Intervention: A Subgroup Analysis of the PRESERVE Trial. JACC Cardiovasc Interv 2019; 11:2254-2261.

Abstract
OBJECTIVES The aim of this study was to compare intravenous (IV) sodium bicarbonate with IV sodium chloride and oral acetylcysteine with placebo for the prevention of contrast-associated acute kidney injury (CAAKI) and intermediate-term adverse outcomes. BACKGROUND Data are conflicting on the optimal strategy to reduce CAAKI and related complications after percutaneous coronary intervention (PCI). METHODS The PRESERVE (Prevention of Serious Adverse Events Following Angiography) trial used a 2 × 2 factorial design to randomize 5,177 patients with stage III or IV chronic kidney disease undergoing angiography to IV 1.26% sodium bicarbonate or IV 0.9% sodium chloride and 5 days of oral acetylcysteine or placebo. A subgroup analysis was conducted of the efficacy of these interventions in patients who underwent PCI during the study angiographic examination. The primary endpoint was a composite of death, need for dialysis, or persistent kidney impairment at 90 days; CAAKI was a secondary endpoint. RESULTS A total of 1,161 PRESERVE patients (mean age 69 ± 8 years) underwent PCI. The median estimated glomerular filtration rate was 50.7 ml/min/1.73 m2 (interquartile range: 41.7 to 60.1 ml/min/1.73 m2), and 952 patients (82%) had diabetes mellitus. The primary endpoint occurred in 15 of 568 patients (2.6%) in the IV sodium bicarbonate group and 24 of 593 patients (4.0%) in the IV sodium chloride group (odds ratio: 0.64; 95% confidence interval: 0.33 to 1.24; p for interaction = 0.41) and in 23 of 598 patients (3.8%) in the acetylcysteine group and 16 of 563 patients (2.8%) in the placebo group (odds ratio: 1.37; 95% confidence interval: 0.71 to 2.62; p for interaction = 0.29). There were no significant between-group differences in the rates of CAAKI. CONCLUSIONS Among patients with CKD undergoing PCI, there was no benefit of IV sodium bicarbonate over IV sodium chloride or of acetylcysteine over placebo for the prevention of CAAKI or intermediate-term adverse outcomes.

Abstract
If IQs continue to rise over generation, why has the world been unable to solve basic recurrent problems? This paper argues that creativity, which is overlooked in IQ tests and showing no signs of a similar increase, may be part of the reason of why the Flynn Effect has not led to a better world. Creativity's predictive power for traditional positive outcomes, such as school or work performance, is significant but slight. However, there are other ways that creativity can help to make a better world. Two exemplar ways that are discussed in this paper are how creativity can (a) help people lead happier and more meaningful lives and (b) focus a spotlight on talented members of underrepresented groups who are overlooked by traditional measures. Both of these directions can lead to a world that is better equipped to solve larger issues.

Abstract
BACKGROUND Intravenous sodium bicarbonate and oral acetylcysteine are widely used to prevent acute kidney injury and associated adverse outcomes after angiography without definitive evidence of their efficacy. METHODS Using a 2-by-2 factorial design, we randomly assigned 5177 patients at high risk for renal complications who were scheduled for angiography to receive intravenous 1.26% sodium bicarbonate or intravenous 0.9% sodium chloride and 5 days of oral acetylcysteine or oral placebo; of these patients, 4993 were included in the modified intention-to-treat analysis. The primary end point was a composite of death, the need for dialysis, or a persistent increase of at least 50% from baseline in the serum creatinine level at 90 days. Contrast-associated acute kidney injury was a secondary end point. RESULTS The sponsor stopped the trial after a prespecified interim analysis. There was no interaction between sodium bicarbonate and acetylcysteine with respect to the primary end point (P=0.33). The primary end point occurred in 110 of 2511 patients (4.4%) in the sodium bicarbonate group as compared with 116 of 2482 (4.7%) in the sodium chloride group (odds ratio, 0.93; 95% confidence interval [CI], 0.72 to 1.22; P=0.62) and in 114 of 2495 patients (4.6%) in the acetylcysteine group as compared with 112 of 2498 (4.5%) in the placebo group (odds ratio, 1.02; 95% CI, 0.78 to 1.33; P=0.88). There were no significant between-group differences in the rates of contrast-associated acute kidney injury. CONCLUSIONS Among patients at high risk for renal complications who were undergoing angiography, there was no benefit of intravenous sodium bicarbonate over intravenous sodium chloride or of oral acetylcysteine over placebo for the prevention of death, need for dialysis, or persistent decline in kidney function at 90 days or for the prevention of contrast-associated acute kidney injury.

Abstract
The Homocysteine Study (HOST) Veterans Affairs Cooperative Studies Program No. 453, is a prospective, randomized, two arm, double blind study of patients with end stage renal disease (ESRD) or advanced chronic kidney disease (ACKD, defined as an estimated creatinine clearance of 30 ml/min or less). Its primary objective is to determine whether administration of high doses of three vitamins, folic acid, vitamin B6 and vitamin B12, to lower the high plasma homocysteine levels, will reduce all cause mortality. The secondary objectives are to examine whether the treatment lowers the incidence of myocardial infarction, stroke, amputation of a lower extremity, a composite of death and the foregoing three events, the plasma homocysteine level, and, in ESRD patients undergoing hemodialysis, thrombosis of the vascular access. A unique feature of this trial is that after initial evaluation at enrollment and one return visit the follow up is exclusively by phone (or, if necessary, by mail). The subject is contacted every three months throughout the duration of the study from a central location. The study drug is shipped to the patient from a central location rather supplied locally. In a two year enrollment period, 2006 patients are to be enrolled. The duration of the observation period is four to six years. Data will be stored and analyzed at a coordinating center. The study design has the power to detect a reduction in all cause mortality rate of 17%. Issues related to the unique features of the design of this study are discussed.

Abstract
In laser-driven acceleration, ultra-short and intense laser pulses are focussed on targets to generate beams of ionising radiation. One of the most important issues to be addressed is personal monitoring. While traditional dosemeters were designed primarily for measurements in continuous fields, dosemeters for laser laboratories must be capable of working in pulsed fields of pulse length below 1 ps, in a single-shot regime up to the repetition rate of 1 kHz. Responses of conventional dosemeters (films, polyallyldiglycol carbonate, electronic personal dosemeter) to proton bunches of up to 30 MeV energy produced by South Korean PW laser system at the Advanced Photonics Research Institute, Gwangju Institute of Science and Technology were studied, both by means of Monte Carlo simulations and experimentally.

Abstract
Background A lack of advanced healthcare information systems and validated scientific cohorts in Nicaragua makes it difficult to estimate disease prevalences and other public health statistics. Although there is concern of an “epidemic” of chronic kidney disease (CKD) in this country, statistics regarding its magnitude are derived from only a small number of non-representative studies. Budgetary constraints and the logistical problems of maintaining a study cohort make longitudinal studies difficult. The Rivas Cohort was created to measure disease burden of CKD and other public health priorities in the Department of Rivas, Nicaragua. Using primarily volunteer research students and technologic innovation including GPS, digital photography and point of care biochemical analysis, the ability to establish a longitudinal chronic disease cohort is demonstrated. Methods Subjects were recruited from consecutive adjacent households in thirty-two randomly selected communities in the ten municipalities that comprise the Department of Rivas in southern Pacific coastal Nicaragua. The study was conducted in two phases. In the first phase, subjects were enrolled into the cohort and consented for future re-contact. In Phase II, conducted two years later, attempts were made to re-contact 400 of these subjects for additional data collection. Demographic, lifestyle, occupational, exposure and health data was collected for both phases of the study. Blood and urine testing and height, weight and blood pressure measurements were also performed. GPS coordinates of homes were recorded and maps of remote communities created. Results Of 1397 adults living in 533 households approached for participation a total of 1242 (89 %) were enrolled in the cohort. The median age is 41 years and 43 % are male, demographics in agreement with Nicaraguan census data for the Department of Rivas. During Phase II we attempted to re-contact 400 subjects for a follow-up study of CKD. It was possible to re-contact 84 % of these participants and of those re-contacted 95 % agreed to participate in the follow-up study. Of subjects that were not successfully re-contacted the majority had either moved (32) or were not at home (22) at the time of the study team visits. Conclusion The Rivas Cohort Study enrolled a representative sample of 1242 adults living in the Department of Rivas, Nicaragua. The high re-contact and participation rates at two years suggests that the cohort is suitable for long-term studies and presents opportunities for investigations of disease prevalence, incidence, treatment and other public health matters. GPS coordinates and maps are available for future researchers who wish to use the cohort for additional studies.

Abstract
Abstract
BACKGROUND: Urinary tract infection is one of the commonest paedi-atric infections, and important to diagnose or exclude in young children with fever. Limitations exist with all current urine collection methods, guidelines vary, and clinicians have different preferences. Clean catch urine (CCU) is a preferred non-invasive collection method and is convenient and painless compared to suprapubic aspirate and catheterisation. However, it can be unreliable and time-consuming, with high rates of sample contamination and collection failure. Only 12% void within 5 minutes based on recent data. An ideal method of urine collection would be fast, reliable and simple. Suprapubic stimulation may trigger involuntary parasympathetic detrusor contraction, inducing voiding via early childhood exteroceptive somato-bladder reflexes.
OBJECTIVES: We conducted a pilot study using a novel method (termed ‘Quick-Wee’) of gentle cutaneous suprapubic stimulation with saline-soaked gauze, to hasten voiding for non-invasive urine collection.
DESIGN/METHODS: Prospective pilot study of 40 pre-continent children age 1-24 months requiring CCU in a paediatric emergency department in Australia. Standard CCU was augmented by 5 minutes of suprapubic cutaneous stimulation (Quick-Wee method), with either cold (3 degrees Celsius) or room-temperature saline-soaked gauze. PRIMARY OUTCOME: Void <5 minutes. SECONDARY OUTCOMES: Successful catch of sample (if voids), contamination rate, parental/clinician satisfaction with technique.
RESULTS:
CONCLUSION: Gentle cutaneous suprapubic stimulation with saline-soaked gauze appears to be a promising technique with 30% voiding in <5 minutes, a rate higher than observed without such stimulation. A randomised controlled trial comparing Quick-Wee to standard CCU without suprapubic stimulation is now underway.

Abstract
Abstract
BACKGROUND: Young children frequently require investigation for urinary tract infection (UTI). Clean catch urine (CCU) is a common urine collection method in pre-continent children but can be time consuming or unsuccessful, and contaminated cultures may lead to an inability to diagnose or exclude UTI. There are few data available examining the success and time required for CCU and factors influencing contamination. We hypothesise that time taken to obtain CCU influences contamination, due to accidental contamination during collection.
OBJECTIVES: To determine the time taken to obtain CCU in pre-conti-nent children, and if time to collection is related to the contamination rate.
DESIGN/METHODS: Prospective observational study of CCU collection in pre-continent children aged 2-48 months at a paediatric emergency department in Australia. A standardised CCU collection protocol was used. Primary outcome was time to first void; secondary outcomes were success of obtaining (catching) CCU and contamination of urine cultures obtained. Contamination was defined as per hospital microbiology standards. Descriptive analysis of time to void included median and interquartile range (IQR). We performed a regression analysis of key factors possibly related to contamination, including age, sex and time to collection.
RESULTS: Of the 218 recruited patients, 61% were male, mean age 11.4 months (SD 8.5). The main indication for CCU was: 128 fever of unknown origin (59%), 31 vomiting (14%), 27 specifically suspected UTI (12%), 32 other reason (15%). From first CCU attempt, 174 voided (80%) of which 139 were successful catches (64%) and 34 were missed on voiding (16%). 44 first CCU attempts were stopped before voiding (20%), 26 patients had 2 attempts (12%), and 2 patients had 3 CCU attempts (1%). Median time to first void was 25 minutes (IQR 8 – 49). 27 children (12%) voided <5 minutes, 33 (19%) voided >1hr. Of the 130 patients who had urine culture results available, 50 were contaminated (38%). There was no significant difference in contamination rate by age, sex or time to sample collection. Of 218 patients where ED clinicians set out to collect CCU in the emergency department, only 80 (37%) resulted in a successful CCU attempt with an uncontaminated culture.
CONCLUSION: Contamination rates are high in clean catch urine, but not related to the time taken for sample collection. CCU attempts are often unsuccessful, and have a low diagnostic yield for investigation of UTI in young children in clinical practice.

Can. J. Anim. Sci. 95: 539–542. The objective of this study was to measure the ammonia concentrations in the microenvironment of the calf housing area on a sample of commercial dairies in Ontario under typical management conditions. Two approaches were used to measure ammonia concentrations: (1) weekly on four farms for a period of 8 wk and (2) one-time samples were taken from the calf areas on 15 other farms. The results indicated that ammonia levels are managed below the existing maximum threshold provided in the national dairy code of practice.

Abstract
BACKGROUND There is no standard treatment for patients with severe anemia who refuse blood transfusion or cannot receive red blood cells. CASE REPORT After an orthotopic liver transplantation, an elderly Jehovah's Witness who refused blood transfusion presented with severe acute anemia with hemorrhagic shock. The calculated red blood cell loss was near 70%. Associated with surgical treatment and supportive measures, the patient was treated with high-dose erythropoietin and ferric carboxymaltose. RESULTS The patient presented a rapid increase in hemoglobin concentration and reticulocyte count with resolution of hemorrhagic shock after the proposed pharmacologic treatment combined with local hemostatic measures. She was transferred to a low-risk unit 4 days after transplantation and was discharged from the hospital on day 10. The hemoglobin concentration was normal 35 days after the bleeding event. CONCLUSION This case demonstrated that a protocol with high-dose erythropoietin and ferric carboxymaltose may be an option for patients with severe anemia who refuse blood transfusion or cannot receive red blood cells.

Abstract
BACKGROUND AND OBJECTIVE The optimal BP target to reduce adverse clinical outcomes in patients with CKD is unclear. This study examined the relationship between BP and death, cardiovascular events (CVEs), and kidney disease progression in patients with advanced kidney disease. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The relationship of systolic BP (SBP), diastolic BP (DBP), and pulse pressure (PP) with death, CVE, and progression to long-term dialysis was examined in 1099 patients with advanced CKD (eGFR≤30 ml/min per 1.7 3m(2); not receiving dialysis) who participated in the Homocysteine in Kidney and ESRD study. That study enrolled participants from 2001 to 2003. Cox proportional hazard models were used to examine the association between BP and adverse outcomes. RESULTS The mean±SD baseline eGFR was 18±7 ml/min per 1.73 m(2). During a median follow-up of 2.9 years, 453 patients died, 215 had a CVE, and 615 initiated long-term dialysis. After adjustment for demographic characteristics and confounders, SBP, DBP, and PP were not associated with a higher risk of death. SBP and DBP were also not associated with CVE. The highest quartile of PP was associated with a substantial higher risk of CVE compared with the lowest quartile (hazard ratio [HR], 1.67; 95% confidence interval [95% CI], 1.10 to 2.52). The highest quartiles of SBP (HR, 1.28; 95% CI, 1.01 to 1.61) and DBP (HR, 1.36; 95% CI, 1.07 to 1.73), but not PP, were associated with a higher risk of progression to long-term dialysis compared with the lowest quartile. CONCLUSIONS In patients with advanced kidney disease not undergoing dialysis, higher PP was strongly associated with CVE whereas higher SBP and DBP were associated with progression to long-term dialysis. These results suggest that SBP and DBP should not be the only factors considered in determining antihypertensive therapy; elevated PP should also be considered.
