Association between maternal blood lipids during pregnancy and offspring growth trajectories in a predominantly macrosomic cohort: findings from the ROLO longitudinal birth cohort study. Eur J Pediatr 2023; 182:5625-5635. [PMID: 37819419 DOI: 10.1007/s00431-023-05251-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Revised: 09/26/2023] [Accepted: 10/01/2023] [Indexed: 10/13/2023]
Abstract
The purpose of this study is to examine associations between maternal lipid profiles in pregnancy and offspring growth trajectories in a largely macrosomic cohort. This is a secondary analysis of the ROLO birth cohort (n = 293), which took place in the National Maternity Hospital, Dublin, Ireland. Infants were mostly macrosomic, with 55% having a birthweight > 4 kg. Maternal mean age was 32.4 years (SD 3.9 years), mean BMI was 26.1 kg/m2 (SD 4.4 kg/m2) and 48% of children born were males. Total cholesterol, high density lipoprotein cholesterol (HDL-cholesterol), low density lipoprotein cholesterol (LDL-cholesterol) and triglycerides were measured from fasting blood samples of mothers at 14 and 28 week gestation. The change in maternal lipid levels from early to late pregnancy was also examined. Offspring abdominal circumference and weight were measured at 20- and 34-week gestation, birth, 6 months, 2 years and 5 years postnatal. Linear spline multilevel models examined associations between maternal blood lipid profiles and offspring growth. We found some weak, significant associations between maternal blood lipids and trajectories of offspring growth. Significant findings were close to the null, providing limited evidence. For instance, 1 mmol/L increase in maternal triglycerides was associated with faster infant weight growth from 20- to 34-week gestation (0.01 kg/week, 95% CI - 0.02, - 0.001) and slower abdominal circumference from 2 to 5 years (0.01 cm/week, 95% CI - 0.02, - 0.001). These findings do not provide evidence of a clinically meaningful effect. Conclusion: These findings raise questions about the efficacy of interventions targeting maternal blood lipid profiles in pregnancies at risk of macrosomia. New studies on this topic are needed. What is Known: • Maternal fat accumulation during early pregnancy may potentially support fetal growth in the third trimester by providing a reserve of lipids that are broken down and transferred to the infant across the placental barrier. • There are limited studies exploring the impact of maternal lipid profiles on infant and child health using growth trajectories spanning prenatal to postnatal life. What is New: • Maternal blood lipid profiles were not associated with offspring growth trajectories of weight and abdominal circumference during pregnancy up to 5 years of age in a largely macrosomic cohort, as significant findings were close to the null, providing limited evidence for a clinically meaningful relationship. • Strengths of this work include the use of infant growth trajectories that span prenatal to postnatal life and inclusion of analyses of the change of maternal lipid levels from early to late pregnancy and their associations with offspring growth trajectories from 20-week gestation to 5 years of age.

Abstract
Abstract
Background
The SSKIN Bundle is a care bundle in which each component acts as an intervention in preventing pressure ulcers. SSKIN stands for Surface, Skin Inspection, Keep Moving, Incontinence Management, and Nutrition. This quality improvement initiative outlines the introduction of the SSKIN Bundle in an attempt to address the issue of pressure ulcers in a rehabilitation hospital. There is a significant amount of research attesting to the physical, psychological, and economic impact pressure ulcers have on patients, particularly older adults.
Methods
Following the Health Service Executive (HSE) Pressure Ulcer to Zero (PUTZ) campaign (HSE National Wound Management Guidelines 2019), this initiative was introduced to the hospital by an interdisciplinary committee in February 2019. Patients who met the inclusion criteria were regularly assessed using the SSKIN Bundle. Data was visually audited via the PUTZ safety cross and analysed using Run Charts.
Results
Results showed a clear decrease in the number of pressure ulcers following introduction of the SSKIN Bundle. Within a six-month timeframe and following the introduction of the SSKIN Bundle, the incidence percentage of newly acquired pressure ulcers was reduced by 50%. Despite incidences where partial increases occurred, this was quickly rectified by facilitating targeted education sessions to staff and the appointment of a tissue viability nurse.
Conclusion
The conclusions of this campaign ultimately found that the introduction of a SSKIN Bundle helped to improve staff knowledge on the monitoring, recognition, grading, and prevention of pressure ulcers. The visual of the safety cross worked particularly well as a means to tailor this education where knowledge gaps existed.

The effectiveness of exercise interventions to increase physical activity in Cystic Fibrosis: A systematic review. J Cyst Fibros 2021; 21:272-281. [PMID: 34753671 DOI: 10.1016/j.jcf.2021.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2021] [Revised: 10/10/2021] [Accepted: 10/25/2021] [Indexed: 11/17/2022]
Abstract
Physical activity (PA) and exercise have numerous benefits in Cystic Fibrosis (CF) including improved lung function, exercise capacity and quality of life. Despite these benefits, the effectiveness of interventions to promote PA in this population are still largely unknown. The objective of this review was to synthesise existing research and determine whether exercise interventions are effective in promoting PA in people with CF. Using the PRISMA guidelines, a comprehensive search was conducted. Fifteen studies (463 participants) met the inclusion criteria. Eleven studies demonstrated improvements in PA in both short- and long-term interventions. However, the interventions were variable across the included studies, with a large inconsistency in PA assessment tools used. Aerobic training and activity counselling were the two elements identified in this review which most consistently improved PA. Future research should consider larger sample sizes and the use of accurate instruments to assess and track PA levels longitudinally.

Effect of supplement crude protein concentration on milk production over the main grazing season and on nitrogen excretion in late-lactation grazing dairy cows. J Dairy Sci 2021; 105:347-360. [PMID: 34635358 DOI: 10.3168/jds.2021-20743] [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: 05/14/2021] [Accepted: 08/24/2021] [Indexed: 11/19/2022]
Abstract
The objectives of this study are to evaluate the effects of (1) a potential interaction between supplement crude protein (CP) concentration and differing cow genotypes on milk production, (2) differing cow genotypes on milk production, and (3) decreasing the supplement CP concentration on milk production and N excretion during the main grazing season within a spring-calving herd. A 2 × 2 factorial arrangement experiment, with 2 feeding strategies [14%; n = 30 (lower CP; LCP) and 18%; n = 28 (higher CP; HCP) CP concentrate supplements] offered at varying levels according to pasture availability and days in milk (DIM) was conducted over the main grazing season from April 3 to September 3, 2019, at University College Dublin Lyons Farm. Cows were also grouped into 2 genotype groups: lower milk genotype; n = 30 [LM; milk kg predicted transmitting ability (PTA): 45 ± 68.6 (mean ± SD); fat kg PTA: 10 ± 4.9; and protein kg PTA: 7 ± 2.3] and higher milk genotype; n = 28 [HM; milk kg PTA: 203 ± 55.0; fat kg PTA: 13 ± 3.8; and protein kg PTA: 10 ± 2.4]. A total of 46 multiparous and 12 primiparous (total; 58) Holstein Friesian dairy cows were blocked on parity and balanced on DIM, body condition score, and Economic Breeding Index. Cows were offered a basal diet of grazed perennial ryegrass pasture. The N partitioning study took place from August 25 to 30, 2019 (187 ± 15.2 DIM). No interactions were observed for any milk production or milk composition parameter. No effect of supplement CP concentration was observed for any total accumulated milk production, daily milk production, or milk composition parameter measured. The HM cows had increased daily milk yield (+1.9 kg), fat and protein (+0.15 kg), and energy-corrected milk (+1.7 kg), compared with the LM cows. Furthermore, HM cows had decreased milk protein concentration (-0.1%) compared with LM cows. For the N partitioning study, cows offered LCP had increased pasture dry matter intake (PDMI; +0.9 kg/d), dietary N intake (+0.022 kg/d), feces N excretion (+0.016 kg/d), and decreased N partitioning to milk (-2%), and N utilization efficiency (-2.3%). In conclusion, offering cows LCP had no negative influence on milk production or milk composition over the main grazing season where high pasture quality was maintained. However, any potential negative effects of offering LCP on milk production may have been offset by the increased PDMI. Furthermore, offering cows LCP decreased N utilization efficiency due to the higher PDMI and feed N intake associated with cows on this treatment in our study.s.

Abstract
BACKGROUND With declining specialist occupational physician (OP) numbers, there is increasing recognition of the importance of non-specialist physicians in occupational health (OH) service delivery, yet to date, this physician group remains understudied and their competency requirements poorly understood. AIMS To evaluate the quality of a sample of non-specialist OH reports and compare these with specialist reports. METHODS A retrospective peer review audit of a convenience sample of 200 consecutive non-specialist and specialist OH reports from an Irish OH service using an assessment form based on the modified Sheffield Assessment Instrument for Letters SAIL(OH)1. RESULTS Of the 200 peer reviewed OH reports, 159 (80%) were from non-specialists. For all questions, 87% and above of non-specialist reports were 'satisfactory' or 'above expected'. On the overall assessment, out of 10, the mean non-specialist report score was 6.8 (standard deviation (SD) 3-10) and the specialist score was 7.3 (SD 3-10). Comparatively, non-specialist reports highlighted legal/ethical issues marginally more and adhered slightly better to contractual/ethical/legal boundaries, while specialist reports fared better in addressing manager's questions, in their structure and clarity and in covering all significant aspects of the case, particularly if the case was complex. CONCLUSIONS Our findings demonstrate a high standard of OH report quality in this sample of non-specialist OPs that is consistent across all key OH report components. Potential development areas are also identified that can inform education/training tailored to this physician group and assist in competency standard-setting.

Abstract
OBJECTIVES Clinical case complexity is an inherent factor in occupational health (OH), yet it is poorly defined and understood. Our aim was to identify the multiple sources of complexity in OH and propose a conceptual complexity framework model for clinical OH practice. METHODS Through a scoping review, expert panel consensus, and content analysis of OH clinical case reports, we identified relevant complexity-contributing factors (CCFs) specifically tailored to the OH setting, which we defined and validated. RESULTS The proposed model consists of three primary domains (PDs); health factors, workplace factors and biopsychosocial factors. Twenty-seven CCFs are described and defined within these PDs. CONCLUSIONS This work lays the foundation for improved understanding, identification, and assessment of complexity in OH. This is imperative for ensuring high quality clinical practice standards, identifying training needs and appropriate triaging/resource allocation.

Abstract
Attaining professional contentment can be challenging for many. Academic success, psychosocial support, and the confidence to provide excellent clinical care at the workplace are key pillars that can help build a sense of meaning in a career. The role of mentorship in facilitating these key pillars at different stages of pediatric anesthesia training and new independent practice is instrumental. For mentees aspiring for a career in pediatric anesthesia, there are several points of focus. Mentees should seek out mentors early in training, build on these relationships, and explore opportunities for peer mentorship as they advance in their career. For mentors, introducing mentees to the clinical and academic aspects of pediatric anesthesia and setting the foundation for the mentee to advance in their career can be both gratifying and stimulating. In this article, we explore the development and progression of a mentor-mentee relationship through training to the early career stage and its role in developing a meaningful career in pediatric anesthesia.

Abstract
BACKGROUND In this Occupational Health Department (OHD), a 'telephone first' approach was introduced to triage management referrals with potential to convert to Telephone Independent Medical Assessment (TIMA). Telephone consultation has been widely used in the UK's NHS in the occupational health setting. AIMS To evaluate TIMA effectiveness and efficiency of OHD resources; comparing the outcome of a triage call compared to previous default allocation of next available appointment, percentage of telephone triage calls converted to TIMA and appointment waiting times. To assess use of OHD resources arising from TIMA. To evaluate service user satisfaction following TIMA. To examine service user characteristics. METHODS As management referrals were received, service users were given a telephone contact. Data were collected and anonymized regarding service users, who also consented to receive feedback questionnaire. Cross-sectional analysis of this management referral cohort was carried out. RESULTS Two hundred and sixty-one management referrals were received in the specified period. Eighty per cent had a TIMA carried out (n = 208); 64% of management referrals with TIMA had a report issued (n = 166). Response rate to feedback questionnaire was 38% (n = 70); 94% of survey participants found TIMA acceptable going forward for management referrals (n = 66). CONCLUSIONS Introduction of a 'telephone first' approach resulted in improved efficiency of this OHD, allowing maximum workforce planning, and positive service user feedback.

Abstract
BACKGROUND Opioid therapy in pediatrics may be particularly prone to error, yet the incidence of opioid-related medication error and harm has not yet been described in the pediatric inpatient setting. METHODS We reviewed a prospectively compiled medication safety database from November 1, 2012 to October 31, 2017. Reports originated from voluntary reporting, hospital code events, naloxone administrations, and reports of unexpected experiences of patient pain. Time, location, error characteristics, drug, route, prescription, error phase, mechanisms, harm, and outcome were collected for all reports. Error and harm were classified by the National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) system. RESULTS Over 697 opioid medication safety reports were included during the study period. Opioids were administered at a rate of 79.26 administrations per 100 patient bed days, with morphine and hydromorphone administered at 62 versus 15 administrations per 100 bed days, respectively. Overall error rate was 0.94 errors per 103 patient days. Although the absolute rate of error reporting was greater for morphine (0.65 errors reported per 103 opioid administrations) than for hydromorphone, the adjusted incidence of harm was 0.211 per 103 hydromorphone administrations compared to 0.086 per 103 morphine administrations. 47 opioid errors resulted in harm, and administration errors (29) were almost twice as common as prescribing errors (15). CONCLUSIONS We report and aim to establish a comparative reference point for incidence of opioid-related error and harm adjusted for both hospital bed days and total opioid administrations within the pediatric hospital inpatient setting based on the above findings.

Abstract
Target station 1 (TS1) is currently in the implementation stage of a large sustainability project to continue future operation, in addition to making improvements to the neutron performance, ease of operation, and various other factors (J. Phys.: Conf. Ser. 1021 (2018) 012053). One aspect of this project is the extraction of the current irradiated equipment situated within the target area to enable the replacement of the target, reflector and moderator assembly (TRaM). This new assembly will be modular to allow any future upgrades to be installed swiftly. Removal of the current TRaM systems support structure is discussed within this paper. This extraction comes with challenges; due to its abnormal size, the welded structure cannot simply be placed in a shielded flask and removed, it instead must be cut up into 2 sections inside the remote handling cell (RHC) (J. Phys.: Conf. Ser. 1021 (2018) 012077). Testing has been completed using a gravity fed hydraulic bandsaw, and various components have been manufactured to allow ease of adjustment using the remote handling system. However, there is still work to be done before the shutdown in 2020.

Abstract
BACKGROUND Prescription opioids have been extensively to manage postoperative pain in children. A growing body of evidence from the adult literature, suggests however, that healthcare providers may be prescribing far more opioids than required, with some studies demonstrating equivalent post-operative pain and clinical outcomes with their omission. OBJECTIVE The objectives of this prospective study were to assess the current heterogeneity of practice in post-operative opioids prescription following day case hypospadias surgery, to establish a streamlined discharge protocol, and to reduce the use of post-operative opioid prescription by 30% within a 4 month period through the use of systemic forcing functions and education. STUDY DESIGN This prospective study was approved by the Quality Improvement (QI) sub-committee of the hospital's Research and Ethics Board (REB) and was compliant with the Standards for Quality Improvement Reporting Excellence (SQUIRE 2.0) guidelines. Recruited parents (n = 84) were contacted for telephone interview following a combined intervention of education and omission of post-operative opioids from the discharge prescription. A mixture of qualitative and quantitative techniques were employed including an initial process analysis to assess current opioid use, the creation of balancing measures, and the creation of Plan-Do-Study-Act cycles. Age, procedure, post-operative outcomes and opioid prescription data were recorded over a period of 6 months in 2019. RESULTS Initial measures in our process analysis demonstrated significant institutional practice variation amongst our 84 post-intervention patients. Our process and fidelity measures confirmed 100% information provision. Following the point of intervention, there was a significant and sustained drop in opioid prescription, with an absolute reduction of 35%, and a relative reduction of 56%. There was no significant difference in patient age, pain scores, or outcomes pre- and post-intervention. DISCUSSION We have shown in this study that a sustainable decrease in post-operative opioid prescriptions following hypospadias surgery is possible. We managed to achieve a relative reduction 56% which is comparable to other specialties, however, did it within a quality improvement framework to ensure fidelity and no adverse balancing measures. We also managed to reduce the number of doses prescribed in those receiving opioids post-intervention at week 9. CONCLUSION Our study demonstrates opioids can be safely omitted in hypospadias cohorts without any adverse clinical outcomes or balancing measures. We recommend that opioids be used extremely judiciously in this population in order to minimize exposure in children.

Abstract
Peripheral intravenous placement in children can be challenging. Different techniques have been used to improve first pass success rates in children with known history of difficult venous access including surface landmarking, local warming, transillumination, ultrasonography, epidermal nitroglycerin, central venous access, intraosseous placement, and venous cutdown. Among these, ultrasound guidance has garnered the most interest among anesthesiologists. The cumulative literature surrounding the utility of ultrasound-guided peripheral intravenous placement in children with and without difficult venous access has shown mixed results. Literature on the utility of ultrasound guidance for peripheral intravenous placement in children under deep sedation or anesthesia is limited but encouraging. This review summarizes the overall evidence for ultrasound-guided peripheral intravenous placement in children with difficult venous access under deep sedation or general anesthesia. Furthermore, five subtly varying approaches to ultrasound-guided peripheral intravenous placement with their advantages and disadvantages will be discussed. One of these five approaches is Dynamic Needle Tip Positioning. Utilizing a short axis out of plane ultrasound view, this promising technique allows for accurate needle tip localization and may increase the success rate of peripheral intravenous placement, even in small children, under deep sedation, or general anesthesia.

Abstract
Study Objectives Previous research has suggested that general anesthetics can disturb postoperative sleep patterns by affecting the sleep-wake cycle. The objective was to identify the effects of general anesthetics on sleep quality and related behavioral changes in children. Methods This was a prospective, observational case-control study with children, aged 18 months to 8 years, undergoing general anesthesia for elective surgery. Participants wore an actigraph for 7 days on three occasions: prior to surgery, the immediate postoperative period, and 3 months after surgery. Data regarding behavior patterns were collected using behavioral assessments at baseline, the first postoperative week, and 3 months following surgery. Results Thirty-one participants (mean age 4.8 ± 2.0 years, 81% male) underwent urologic or otolaryngologic surgery. The median (interquartile range) anesthetic duration was 132.0 (80.0-184.0) min. No significant differences were found in sleep efficiency, total sleep time, wake time after sleep onset, or sleep onset latency between baseline, 7 day postoperative period, and the 3 month follow-up. No significant differences were found in sleep-related behavioral metrics including internalizing and externalizing behaviors, and executive functioning. Data were compared with a control group of 18 participants (mean age 5.3 ± 1.8 years, 61% male). No significant differences were found in sleep patterns and related behavioral metrics between both groups. Conclusions In this study, general anesthesia did not result in disturbed sleep or associated negative behavioral changes in otherwise healthy children undergoing elective surgeries of low complexity. Physicians can advise parents that a child's surgery and associated general anesthetic exposure may not result in significant changes in postoperative sleep patterns.

Knowledge translation and process improvement interventions increased pain assessment documentation in a large quaternary paediatric post-anaesthesia care unit. BMJ Open Qual 2018; 7:e000319. [PMID: 30167475 PMCID: PMC6112407 DOI: 10.1136/bmjoq-2018-000319] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2018] [Revised: 04/27/2018] [Accepted: 07/10/2018] [Indexed: 11/03/2022] Open
Abstract
Background Due to inadequate pain assessment documentation in our paediatric post-anaesthetic care unit (PACU), we were unable to monitor pain intensity, and target factors contributing to moderate and severe postoperative pain in children. The purpose of this study was to improve pain assessment documentation in PACU through a process improvement intervention and knowledge translation (KT) strategy. The study was set in a PACU within a large university affiliated paediatric hospital. Participants included PACU and Acute Pain Service nursing staff, administrative staff and anaesthesiologists. Methods The Plan-Do-Study-Act method of quality improvement was used. Benchmark data were obtained by chart review of 99 patient medical records prior to interventions. Data included pain assessment documentation (pain intensity score, use of validated pain intensity measure) during PACU stay. Repeat chart audit took place at 4, 5 and 6 months after the intervention. Intervention Key informant interviews were conducted to identify barriers to pain assessment documentation. A process improvement was implemented whereby the PACU flowsheets were modified to facilitate pain assessment documentation. KT strategy was implemented to increase awareness of pain assessment documentation and to provide the knowledge, skill and judgement to support this practice. The KT strategy was directed at PACU nursing staff and comprised education outreach (educational meetings for PACU nurses, discussions at daily huddles), reminders (screensavers, bedside posters, email reminders) and feedback of audit results. Results The proportion of charts that included at least one documented pain assessment was 69%. After intervention, pain assessment documentation increased to >90% at 4 and 5 months, respectively, and to 100% after 6 months. Conclusion After implementing process improvement and KT interventions, pain assessment documentation improved. Additional work is needed in several key areas, specifically monitoring moderate to severe pain, in order to target factors contributing to significant postoperative pain in children.

Abstract
Laser beam shaping can play a crucial role in improving many laser processes, especially in selective laser patterning of thin films for display devices and solar cells. Typical Gaussian spatial energy distributions can increase damage to the substrate and lead to large crater edge ridges, which are sub-optimal for typical industrial thin film processes. We report on the design, fabrication, and testing of reflective silicon diffractive optics developed for spatial beam shaping at a wavelength of 355 nm. The application of the elements for laser-selective removal of 20 nm indium tin oxide thin films on glass substrates is demonstrated. The design of the phase profile is first generated using the numerical method of computer-generated holography. The phase profiles are realized on a silicon substrate using a novel two-step fabrication technique consisting of a calibrated focused ion beam and an inductively coupled plasma etch. This results in truly grey-scale, blazed diffractive optics, which were analyzed using white light interferometry and atomic force microscopy. Using the diffractive elements with 355 nm nanosecond pulses shows excellent focused spot profiles with a good reproduction of the intended design with a first-order off-axis diffractive efficiency of approximately 80% at a 45 deg angle of incidence.

Abstract
INTRODUCTION Northern Ireland has high mental health needs and a rising suicide rate. Our area has suffered a 32% reduction of inpatient beds consistent with the national drive towards community based treatment. Taking these factors into account, a new Mental Health Crisis Service was developed incorporating a high fidelity Crisis Response Home Treatment Team (CRHTT), Acute Day Care facility and two inpatient wards. The aim was to provide alternatives to inpatient admission. The new service would facilitate transition between inpatient and community care while decreasing bed occupancy and increasing treatment in the community. METHODS All services and processes were reviewed to assess deficiencies in current care. There was extensive consultation with internal and external stakeholders and process mapping using the COBRAs framework as a basis for the service improvement model. The project team set the service criteria and reviewed progress. RESULTS In the original service model, the average inpatient occupancy rate was 106.6%, admission rate was 48 patients per month and total length of stay was 23.4 days. After introducing the inpatient consultant hospital model, the average occupancy rate decreased to 90%, admissions to 43 per month and total length of stay to 22 days. The results further decreased to 83% occupancy, 32 admissions per month and total length of stay 12 days after CRHTT initiation. DISCUSSION The Crisis Service is still being evaluated but currently the model has provided safe alternatives to inpatient care. Involvement with patients, carers and all multidisciplinary teams is maximised to improve the quality and safety of care. Innovative ideas including structured weekly timetable and regular interface meetings have improved communication and allowed additional time for patient care.

Early postoperative patient-controlled analgesia ratio predicts 24-hour morphine consumption and pain in children undergoing scoliosis surgery. J Opioid Manag 2014; 10:39-45. [PMID: 24604568 DOI: 10.5055/jom.2014.0190] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2012] [Revised: 03/31/2013] [Accepted: 10/09/2013] [Indexed: 06/03/2023]
Abstract
BACKGROUND The identification of patients at risk for developing severe postoperative pain and/or opioid-related side effects is difficult due to a lack of sensitive indicators. The patient-controlled analgesia (PCA) ratio of demands to deliveries is a potential tool for early identification of patients who experience severe postoperative pain. The authors hypothesized that the PCA ratio is able to predict morphine requirement in the first 24 hours after scoliosis surgery. METHODS The authors performed a retrospective study of adolescents who had surgery for idiopathic scoliosis. They collected data describing PCA demands and deliveries, morphine consumption, numerical rating scale (NRS) pain scores, opioid related side effects, and duration of hospital stay. Spearman rank analysis assessed association among 4-hour PCA ratios, NRS pain score, and 24-hour morphine consumption. Patients were divided into groups on the basis of PCA ratios <1.5 and ≥1.5. Univariate analysis and multiple regression were used to identify independent factors predictive for increased 24-hour morphine. Mann-Whitney rank-sum and Fisher exact tests were used to compare data. p < 0.05 was considered statistically significant. RESULTS One hundred forty-seven patients were included in the analysis, mean (SD) age and weight were 15 (1.8) years and 55 (27) kg, respectively. There was a significant positive correlation between the 4-hour PCA ratio and initial 24-hour cumulative morphine consumption (r = 0.33, p = 0.0002). Patients with a 4-hour PCA ratio ≥1.5 demonstrated a significantly greater initial 24-hour morphine consumption (p = 0.0002), greater pain scores at 24 hours after surgery (p = 0.02), a greater incidence of at least one opioid-related side effect within the initial 24 hours after surgery, and a longer duration of hospital stay (p = 0.04) compared with those patients with a 4-hour PCA ratio <1.5. PCA ratio ≥1.5, age, and patient sex were predictive for 24-hour morphine consumption. CONCLUSIONS The authors have demonstrated that a PCA ratio of demands/deliveries ≥1.5 is predictive of increased opioid requirements and is associated with greater pain scores in the initial 24 hours after surgery, an increased incidence of opioid-related side effects, and duration of hospital stay.

Abstract
OBJECTIVE No method exists to reliably predict which patients will develop severe postoperative pain. The authors hypothesized that data derived from patient-controlled analgesia (PCA) pumps (specifically the ratio of patient demands to pump deliveries) may predict which patients would develop severe pain after scoliosis repair. SETTING Quaternary, university-affiliated, pediatric hospital. PATIENTS AND PARTICIPANTS Forty American Society of Anesthesiologists I-Il pediatric patients who had undergone elective scoliosis repair and had consented to recruitment to a randomized clinical trial investigating the effects of early morphine administration on remifentanil-induced hyperalgesia. INTERVENTIONS To test the hypothesis of the current study, the authors calculated the PCA ratio of demand to delivery at every 4 hours throughout the first 24 hours after surgery for all the patients recruited to the original study. MAIN OUTCOME MEASURES The authors compared calculated PCA ratios, numeric rating scale pain scores, and cumulative morphine consumption for those patients who developed severe postoperative pain and met the criteria for opioid rotation versus those patients who did not. RESULTS Seven patients required opioid rotation from PCA morphine to PCA hydromorphone. Eight hours after surgery, the median PCA ratio for those seven patients (2.5[range, 1.8-4.3]) was significantly greater than that for all other recruited patients (1.3 [range, 0-2.7]; p < 0.001). CONCLUSIONS Patients who developed severe postoperative pain and met the criteria for opioid rotation demonstrated significantly increased PCA ratios of demand to delivery as early as 8 hours after surgery.

Abstract
Background/Significance: National guidelines recommend women age 40 and older have mammograms every 1-2 years. Since 2000, the Avon Foundation Breast Care Fund (AFBCF), a project of Cicatelli Associates Inc., has supported nonprofit community-based organizations (CBOs) to provide breast health education and outreach to link medically underserved women with free/low-cost breast cancer screening services. These organizations have developed effective strategies for recruiting, retaining and rescreening clients. This evaluation study aims to identify promising practices for effective mammography recruitment, retention and rescreening among un/underinsured, low-income, and racial and/or ethnic minority women.Methods: Twenty of 144 AFBCF-funded CBOs were selected to participate in a retrospective study to determine clients' rescreening rates.CBOs provided de-identified data on mammography screening by age and visit date to determine their rescreening rate, defined as the proportion of female outreach clients age 40+ years receiving a mammogram and subsequent mammogram through that agency within the following 6-18 and/or 18-30 months. CBOs also completed a qualitative survey about program strategies and systems. Qualitative data were linked with rescreening rates to identify promising practices. Survey results were also used to develop a discrete questionnaire administered to 144 AFBCF-funded CBOs to identify which agencies currently employ identified promising practices.Results: Data analysis will be completed in September 2009.Preliminary results indicate that rescreening rates vary widely across agencies, from 15% to over 90%. In addition, findings indicate that some CBOs lack mechanisms to routinely monitor client rescreening. Utilizing unique client identifiers in conjunction with the use of electronic data tracking systems would facilitate tracking clients over time and improve targeted outreach efforts to increase rescreening rates.Discussion: Combined qualitative and quantitative analyses of differences in practices directed at encouraging mammography rescreening among medically underserved women will enable a description of promising practices for increasing rescreening rates in this population. Analysis will include an explanation of mammography rescreening rates among medically underserved women. Agencies with high rescreening rates will be identified and discussion regarding organizational characteristics and practices will be presented. Additionally, unique and innovative strategies for reaching specific populations will be examined.

Abstract
BACKGROUND AND OBJECTIVES Pharmacotherapy is an under-evaluated element of critical care medicine. In order to better understand pharmacotherapy in pediatric critical illness, we evaluated a cohort of emergency admissions to a university-affiliated pediatric intensive care unit (PICU). METHODS A prospective, observational study was performed. Eligible patients were admitted to this medical-surgical ICU for at least 24 hours. The primary outcomes were the number of drug orders written, the number of different medications ordered, and the number of drug administrations. Multiple regression analyses were used to identify factors independently associated with each primary outcome. RESULTS We studied 100 patients with a median age of 40 months (interquartile range [IQR] 9-82), who were admitted for a total of 851 ICU days. These patients received 4419 drug orders and 11 911 intermittent dose-administrations of 241 different medications. Each patient received a median of 29.5 (IQR 16.5-48.5) drug orders, 14 (IQR 9-18.5) different medications, and 58 (IQR 28-129) drug administrations while in the ICU. The most frequent orders were for morphine 457 (10.6%), furosemide (frusemide) 337 (7.8%), potassium 237 (5.5%), lorazepam 226 (5.2%), and albuterol (salbutamol) 158 (3.7%). The duration of PICU stay and severity of illness were independently associated with all primary outcomes. CONCLUSIONS Pharmacotherapy is an active component in the practice of pediatric critical care medicine. We demonstrated that increasing numbers of ordered medications, drug orders, and drug administrations were associated with increasing duration of ICU therapies and the length of ICU stay. These data underscore the potential importance of improved safety and efficacy of medicines used to treat critically ill children.

Abstract
A child with cerebral palsy and carnitine deficiency developed ventricular arrhythmias with loss of cardiac output during elective surgery under general anaesthesia with concomitant epidural analgesia. Sinus rhythm was restored on administration of adrenaline, but hypotension persisted despite resuscitation. Bolus administration of 0.8 ml*kg(-1) (20 ml) lipid emulsion resulted in rapid improvement in cardiac output. Blood samples taken before and after the lipid bolus did not demonstrate toxic concentrations of bupivacaine. This case suggests that carnitine deficiency may increase susceptibility to bupivacaine cardiotoxicity.

Abstract
Mumps is a contagious vaccine-preventable viral disease that is experiencing a revival in students attending second and third level colleges. Large mumps outbreaks have been reported in several countries despite the presence of childhood immunisation programmes over many years, including measles, mumps, and rubella (MMR) vaccination. In 2008, 1,377 cases of mumps were notified in Ireland and 1,734 in the first three months of 2009 (provisional data). This paper reviews the recent epidemiology of mumps in the Mid-West region of Ireland and highlights preventive measures. A substantial proportion of cases were not laboratory-confirmed and it is important that doctors continue to notify suspected cases. In the Irish Mid-West, data from enhanced surveillance shows a high proportion of mumps in the age group 15-24 years. Complications were uncommon and rarely severe. Where data were available, over half of the cases did not recall having received two doses of MMR, but most recalled one dose. Parents should continue to ensure children receive both MMR vaccinations so that uptake is optimal for protection. Steps were taken to increase awareness of the disease in the school, college and university settings. Preventive measures implemented to limit mumps transmission in the school/college setting over recent years included vaccination of close contacts, isolation for five days and hand hygiene.

Abstract
PURPOSE To describe the successful management of priapism secondary to sickle cell anemia in a child using neuraxial analgesia provided via an epidural catheter. CLINICAL FEATURES A seven-year-old male presented with chest crisis and priapism which, following hemoglobin electrophoresis led to a new diagnosis of sickle cell anemia. Epidural management was attempted as an alternative to surgery after failure of more conventional medical and surgical methods to treat the priapism. The patient's clinical condition improved with this intervention and together with further conservative therapy resulted in complete resolution of the priapism. CONCLUSIONS Priapism is a well described complication of sickle cell anemia that is painful and difficult to manage. Surgical intervention is the last therapeutic resort and often results in significant long-term morbidity. This case highlights how select cases of priapism can be successfully managed with epidural neuraxial blockade which not only provides superior analgesia for the often painful conservative treatments, but may also per se impart a direct and salutary therapeutic benefit.

Abstract
BACKGROUND The objective of this study was to determine the intracranial, cardiovascular and respiratory changes induced by conversion to high-frequency oscillator ventilation from conventional mechanical ventilation at increasing airway pressures. METHODS In this study, 11 anaesthetized sheep had invasive cardiovascular and intracranial monitors placed. Lung injury was induced by saline lavage and head injury was induced by inflation of an intracranial balloon catheter. All animals were sequentially converted from conventional mechanical ventilation to high-frequency oscillator ventilation at target mean airway pressures of 16, 22, 28, 34 and 40 cm H(2)O. The mean airway pressure was achieved by adjusting positive end expiratory pressure while on conventional mechanical ventilation, and continuous distending pressures while on high-frequency oscillator ventilation. Cerebral lactate production, oxygen consumption and venous oximetry were measured and analysed in relation to changes in transcranial Doppler flow velocity. Transcranial Doppler profiles together with other physiological parameters were measured at each airway pressure. RESULTS Cerebral perfusion pressure was significantly lower during high-frequency oscillator ventilation than during conventional mechanical ventilation (CMV: 45, 34, 22, 6, 9 mmHg vs. HFOV: 33, 20, 19, 5, 5 mmHg at airway pressures mentioned above, P = 0.02). Intracranial pressure and cerebrovascular resistance increased with increasing intrathoracic pressures (P = 0.001). Cerebral metabolic indices demonstrated an initial increase in anaerobic metabolism followed by a decrease in cerebral oxygen consumption progressing to cerebral infarction as intrathoracic pressures were further increased in a stepwise fashion. Arterial PaCO(2) increased significantly after converting from conventional mechanical ventilation to high-frequency oscillator ventilation (P = 0.001). However, no difference was observed between conventional mechanical ventilation and high-frequency oscillator ventilation when intracranial pressure, metabolic and transcranial Doppler indices were compared at equivalent mean airway pressures. CONCLUSIONS The use of high positive end expiratory pressure with conventional mechanical ventilation or high continuous distending pressure with high-frequency oscillator ventilation increased intracranial pressure and adversely affected cerebral metabolic indices in this ovine model. Transcranial Doppler is a useful adjunct to intracranial pressure and intracranial venous saturation monitoring when major changes in ventilation strategy are adopted.

We have investigated the dependence of the lytic activity of melittin on lipid composition. The lysis of liposomes, measured by following their mass and dimensions when immobilised on a solid substrate, was close to zero when the negatively charged lipids phosphatidyl glycerol or phosphatidyl serine were used as the phospholipid component of the liposome. Whilst there was significant binding of melittin to the liposomes, there was little net change in their diameter with melittin binding reversed upon salt injection. For the zwitterionic phosphatidyl choline the lytic ability of melittin is dependent on the degree of acyl chain unsaturation, with melittin able to induce lysis of liposomes in the liquid crystalline state, whilst those in the gel state showed strong resistance to lysis. By directly measuring the dimensions and mass changes of liposomes on exposure to melittin using Dual Polarisation Interferometry, rather than following the florescence of entrapped dyes we attained further information about the initial stages of melittin binding to liposomes.

Abstract
An optical technique, dual-polarization interferometry, has been used to examine lipid structures at the solid/liquid interface. Changes in the lipid structures, in real time, were examined as a consequence of challenging them with a peptide (melittin) that is known to induce liposome rupture. This work suggests that it should be possible to obtain a better understanding of the detail of the melittin rupture process.
