Implementation of a collaborative online international learning program in nursing education: protocol for a mixed methods study

BACKGROUND

An essential component of becoming a professional nurse is a perspective of global health issues and an awareness of diverse populations. Collaborative online international learning (COIL) using digital technologies, offers meaningful and rewarding opportunities to develop international partnerships between nurses from other countries, without economic, organisational or geographical barriers. Despite reported advantages of using COIL, few COIL interventions have been identified in the nursing literature. The aims of this study are to develop, implement and evaluate a COIL program between Australian and Canadian pre-registration nursing students.

METHODS

The study will utilize a mixed methods approach incorporating pre and post-test surveys, focus groups, and semi-structured interviews of key stakeholders. The design will adhere to The State University of New York (SUNY) COIL's criteria for intercultural/international learning opportunities. Participants will be recruited from nursing programs at an Australian Training and Further Education Institute and a Canadian college. Bennett's stages of intercultural competence will provide the theoretical framework for the research. Four specific research interventions will be developed for this project. For students, there will be an online virtual community to allow students and teachers to communicate, socially connect and share resources with each other. Virtual reality simulations will be employed within a virtual global classroom to promote collaborative, intercultural learning. For faculty, a virtual community of practice will provide a platform for faculty to share education and research ideas and participate in collaborate research opportunities.

DISCUSSION

This study will evaluate the outcomes of a nursing COIL program. It will measure participants' views on COIL, its contribution to student learning, changes in cultural awareness, organisational impact and research productivity. It will provide nursing students with the opportunity to become global leaders in nursing care and for faculty to develop international research skills and outputs. The findings from the study will allow further refinement of future nursing COIL programs.

805 UPPER LIMB FRACTURE PATHWAYS IN FRAILTY ENABLE EARLIER RETURN TO FUNCTION WITH ASSOCIATED REDUCED LENGTH OF HOSPITAL STAY

Introduction

Upper limb fractures are the second most common fracture requiring admission to hospital after hip fracture [Jennison, 2019]. At 1-year 20.5% have died, compared to 29.5% in hip fracture [Wiedl, 2021]. Local Problems: At North Bristol Trust most patients with upper limb fractures and a Clinical Frailty Score ≥ 5 are managed non-operatively on medical wards. Local service evaluation identified a long length of stay of 23 days. Case note review revealed: • Delayed transfers of care (DTOCs) had been managed non-weight bearing in slings for 4–6 weeks. • Non-weight bearing status resulted in DTOC due to declined access to social care and rehabilitation due to perceived health needs. • A high rate of hospital-acquired complications and failure to rehabilitate. • Breakdown in interdisciplinary communication and ownership across the pathway.

Methods

A multidisciplinary QI project was commenced. Using local data through business analytics, clinician and patient feedback, a new Trust guideline was developed for older people with frailty and upper limb fractures. Data collected determined average length of stay before and after implementation of the service change. A standard process control chart was created monitoring the effect of the changes in the pathway. The multidisciplinary team met regularly to make alterations during implementation. The resulting intervention included: • Removal of functional restrictions; allow free use of limb as comfort permits. • Simplified slings and minimised light weight casts. • Proactive integration of orthopaedic plan into CGA documentation. • Proactive interdisciplinary communication across pathways. • Patient information leaflets.

Results

Pre-intervention average length of stay was 23 days. Post-intervention was 14 days.

Conclusion

Proactive, structured management of upper limb fractures in people with frailty is associated with significant reduction in acute hospital length of stay. Next steps include a business case for a frailty trauma specialist therapist embedded into medicine.

Educating health professionals to implement evidence-based falls screening in hospitals

OBJECTIVE

International evidence-based guidelines advise traditional Falls Risk Assessment Tools (FRATs) should not be routinely used to predict the risk of a patient falling in hospital. However, disinvestment from existing services can be challenging. This study applied evidence-based approaches to education design to implement best practice guidelines.

DESIGN

Mixed methods using questionnaires to evaluate health professionals' knowledge of evidence-based falls risk assessment and mitigation, followed by semi-structured interviews with individual health professionals.

SETTING

Five Australian hospitals.

PARTICIPANTS

There were two cohorts per hospital; Cohort 1 (C1) comprised 10 clinical leaders from nursing and allied health professions. Cohort 2 (C2) included clinicians involved in routine hospital falls screening and prevention.

METHODS

46 clinical leaders received a 3-h high quality education workshop on the latest evidence in hospital falls risk assessment and how to implement a new falls screening and management tool. They were also taught the practical skills to deliver a 1-h education session to C2 (n = 129).

RESULTS

The education workshop significantly changed C1's views about evidence-based guidelines for falls screening and prevention. C1 were significantly more likely than C2 to feel confident in assessing falls risk and judging and implementing the best mitigation strategies. After the workshop, C1 were prepared and motivated to educate others on falls prevention and were satisfied with the skills gained. Six months after the workshop, C1 reported feeling more prepared for preventing falls.

CONCLUSION

Health professionals benefitted from an interactive education workshop on how to use a new evidence-based hospital falls screening tool to help mitigate risk. An abridged version of the workshop did not result in long lasting effects. Education is an important element aiding disinvestment from non-evidence-based services, and implementation of clinical guidelines.

Treatment outcomes of patients with Atopic Dermatitis (AD) treated with dupilumab through the Early Access to Medicines Scheme (EAMS) in the UK

BACKGROUND

Dupilumab, a monoclonal antibody against interleukin (IL)-4 receptor alpha that inhibits IL-4/IL-13 signalling is indicated in dermatology for the treatment of moderate-to-severe atopic dermatitis (AD) in adult and adolescent patients 12 years and older and severe AD in children 6-11 years, who are candidates for systemic therapy. Dupilumab received Early Access to Medicines Scheme (EAMS) approval for adults in March 2017.

OBJECTIVES

The purpose of this study was to assess the efficacy outcomes of treatment with dupilumab in EAMS.

METHODS

A retrospective analysis of adult patients enrolled in the dupilumab EAMS in the UK. Scores were assessed at baseline and follow up, including the Eczema Area and Severity Index (EASI), Investigator's Global Assessment Score (IGA) and Dermatology Life Quality Index (DLQI).

RESULTS

Data were available for 57 adult patients treated with dupilumab for at least 12 weeks; 73.6% of patients had received prior treatment with 3 or 4 immunosuppressants. Baseline scores for the EASI and DLQI were 27.93 (standard deviation, SD 13.09) and 18.26 (SD 6.18) respectively. AD severity scores showed statistically significant improvement at week 16±4 weeks (p <0.001 for all). The mean change in EASI was 14.13 points with 66.7% and 36.7% achieving a 50% (EASI-50) and 75% (EASI-75) improvement in EASI, respectively at 16^+/- 4 weeks. IGA scores improved by at least two categories for 75% patients. DLQI scores decreased by a mean of 9.0 points, with 80% patients demonstrating a MCID 4-point improvement. For 85% patients, clinicians rated the treatment response as being either 'better' (19%) or 'much better' (65%).

CONCLUSIONS

Dupilumab is associated with a significant and clinically relevant improvements in AD as measured by patient- and physician-reported outcome measures. Importantly, the clinical efficacy, despite the refractory disease of this EAMS cohort, is comparable to that previously reported in clinical trials.

Education interventions for health professionals on falls prevention in health care settings: a 10-year scoping review

Background

Falls in hospitals are a major risk to patient safety. Health professional education has the potential to be an important aspect of falls prevention interventions. This scoping review was designed to investigate the extent of falls prevention education interventions available for health professionals, and to determine the quality of reporting.

Method

A five stage scoping review process was followed based on Arksey and O’Malley’s framework and refined by the Joanna Briggs Institute Methodology for JBI Scoping Reviews. Five online databases identified papers published from January 2008 until May 2019. Papers were independently screened by two reviewers, and data extracted and analysed using a quality reporting framework.

Results

Thirty-nine publications were included. Interventions included formal methods of educational delivery (for example, didactic lectures, video presentations), interactive learning activities, experiential learning, supported learning such as coaching, and written learning material. Few studies employed comprehensive education design principles. None used a reporting framework to plan, evaluate, and document the outcomes of educational interventions.

Conclusions

Although health professional education is recognised as important for falls prevention, no uniform education design principles have been utilised in research published to date, despite commonly reported program objectives. Standardised reporting of education programs has the potential to improve the quality of clinical practice and allow studies to be compared and evaluated for effectiveness across healthcare settings.

Role of physical fitness in the obesity paradox. Long-term major adverse cardiovascular events in the Women's Ischemia Syndrome Evaluation (WISE)

Background

Emerging data suggests there is an “obesity paradox” where obesity may be protective against cardiovascular morbidity and mortality in patients with cardiovascular disease. However, weight status primarily assessed through body mass index (BMI) is limited in its ability to discern contributions from fat vs. lean muscle mass. Most studies on BMI have not accounted for physical fitness, which is a known modifier of weight status and a potential mediator of effects of obesity on major adverse cardiovascular events (MACE).

Purpose

To investigate the relationship between BMI and physical fitness, measured by self-reported Duke Activity Status Index (DASI) score, with long-term MACE in women evaluated for suspected myocardial ischemia.

Methods

The National Heart, Lung, and Blood Institute Women's Ischemia Syndrome Evaluation (WISE) study is a multicenter prospective cohort study. From 1996–2000, 936 women were enrolled at the time of clinically indicated coronary angiography and assessed with a median follow up of 5.8 (range 0–9 years) for MACE. MACE was defined as a composite of death, nonfatal myocardial infarction, stroke, or congestive heart failure. Proportional hazards regression was used to estimate adjusted hazard ratios of MACE in relation to metabolic status and physical fitness. DASI scores ≥25, equivalent to ≥7 metabolic equivalents [METs]) was used as cut point to define high physical fitness, in our prior studies DASI &gt;25 approximates completion of the second stage of a Bruce treadmill protocol.

Results

Among the 899 women with complete data, 69.5% had low physical fitness (DASI scores &lt;25), 34.9% overweight (BMl ≥25 to 30), 40.5% obese (BMI ≥30). In fit women, obesity was associated with lower hazard ratio for MACE (HR 0.64, p=0.01); while low fitness in normal weight women was associated with 60% excess risk of MACE (HR 1.61, p=0.01) (Figure 1).

Conclusions

Among women undergoing coronary angiography for suspected myocardial ischemia, obesity was inversely related with long-term MACE in physically fit women. Our findings suggest that physical fitness may play a role in the obesity paradox. These results support the inclusion of fitness in understanding the relations between body weight and long-term MACE. The DASI is a simple, self reported tool that can identify higher-risk symptomatic women and should be considered in future investigations and routine examination of normal, overweight and obese women.

0206 Sleep Opportunity and Duration are Related to Risk Injury in Elite Athletes

Introduction

Sleep is essential to musculoskeletal recovery, acquisition of new skills and emotional regulation in athletes. Insufficient sleep is detrimental to performance. Recent publications indicate that sleep duration is related to risk for injury in young athletes. We aimed at analyzing the relation between sleep opportunity and duration and the likelihood of an injury among adult elite athletes.

Methods

We studied 7,237 nights recorded with the Sleeprate application by 71 adult elite athletes from diverse sports, during the period September 2018-October 2019. Night recordings included perceived and measured sleep parameters. In addition, athletes reported their previous day nap duration, injuries and illness status. Out of the total number of nights, 4,205 included reported injury status with no injury and no illness for the previous night. Nightly total time in bed (TIB), TIB including reported naps (TIB24hr) and measured total sleep time (TST) were examined.

Results

Average TIB was significantly shorter (508±77 minutes, mean±STD) in healthy days preceding injuries than in healthy days preceding days with no injury (525±70 minutes, p&lt;.001). Similar results were found when comparing the TIB24hr (injury: 517±83 minutes, no injury: 543±76 minutes, p&lt;.001) and TST (injury: 443±72 minutes, no injury: 457±69 minutes, p&lt;.001).

Conclusion

Average sleep opportunities of the elite athletes in this study were in accordance with their age and workouts load. The time athletes allow themselves as an opportunity for sleep is inversely correlated to the chances of developing an injury. These findings corroborate published research regarding sleep duration and risk of injury in athletes, yet our findings are based on real life data of elite athletes, and demonstrate the importance of sleep as part of the elite or professional athlete’s routine, suggesting that even as little as around 20 minutes of added sleep may be efficient in preventing injury.

CRISPR-Cas9-mediated labelling of the C-terminus of human laminin β1 leads to secretion inhibition

Objectives

The laminins (LM) are a family of basement membranes glycoproteins with essential roles in supporting epithelia, endothelia, nerves and muscle adhesion, and in regulating a range of processes including cell migration, stem cell maintenance and differentiation. However, surprisingly little is known about the mechanisms of turnover and remodelling of LM networks due to lack of appropriate tools to study these processes at the necessary resolution. Recently, the nematode C. elegans ortholog of human the LMβ1 chain was labelled at the C-terminus with the photoconvertible fluorophore Dendra2. Here we used genome editing to establish a similar system in a mammalian cell line as proof of concept for future mammalian models.

Results

CRISPR-Cas9 was used to introduce the Dendra2 sequence at the C-terminus of LMβ1 in the human lung adenocarcinoma cell line A549. Despite expression of the tagged protein within cells, no detectable LMβ1-Dendra2 protein was deposited to the extracellular matrices or conditioned media of edited cells. Moreover, the edited cells displayed reduced proliferation rates. Together, these data suggest that, in humans, addition of C-terminal Dendra2 tag to LMβ1 inhibits LM secretion, and is not a viable approach for use in animal models.

Educating health professionals to optimise falls screening in hospitals: protocol for a mixed methods study

BACKGROUND

Falls in hospitals remain a major challenge to patient safety. All hospitalised adults are at risk of falling during their inpatient stay, though this risk is not always realised by patients and clinicians. This study will evaluate the outcomes of a hospital clinician education program that teaches clinicians how to screen for falls risk and assign mitigation strategies using clinical reasoning, rather than relying on a standardised falls risk assessment tool (FRAT). The education program aims to increase clinician knowledge, motivation and confidence in screening falls risk and selecting individual falls prevention interventions. Perceptions of the education intervention will also be examined.

METHODS

Participants will be a sample of convenience of nurses and allied health professionals from five Australian hospitals. For each hospital there will be two cohorts. Cohort 1 will be clinical leaders who shall receive a three-hour education program on the latest evidence in hospital falls risk assessment and how to implement a new falls screening and management tool. They will also be taught practical skills to enable them to deliver an effective one-hour in-service training session to Cohort 2. Cohort 2 will be recruited from the workforce as a whole and include nurses and other health professionals involved in routine hospital falls screening and prevention. The investigation will be framed on Keller's Model of Motivational Design and Kirkpatrick's evaluation framework. It will involve a mixed methods pre and post-test questionnaire design inclusive of semi-structured telephone interviews, to triangulate the data from multiple approaches.

DISCUSSION

This study will quantify the outcomes of a high-quality clinician education program to increase knowledge of evidence-based practice for falls prevention. It is predicted that positive behavioural changes will occur in health professionals, leading to organisational change and improved patient outcomes. Furthermore, the findings from the study will inform the future refinement of educational delivery to health professionals across hospital sites.

TRIAL REGISTRATION

The study has also been approved by the Australian New Zealand Clinical Trials Registry: Preventing Hospital Falls: Optimal Screening UTN U1111-1225-8450. Universal Trial Number (UTN): U1111-1228-0041 (obtained 5/2/19). Australian New Zealand Clinical Trials Registry (ANZCTR): ACTRN12619000200189 (obtained 12/2/19).

Comparison of sporadic and familial behavioral variant frontotemporal dementia (FTD) in a North American cohort

INTRODUCTION

Behavioral variant frontotemporal dementia (bvFTD) may present sporadically or due to an autosomal dominant mutation. Characterization of both forms will improve understanding of the generalizability of assessments and treatments.

METHODS

A total of 135 sporadic (s-bvFTD; mean age 63.3 years; 34% female) and 99 familial (f-bvFTD; mean age 59.9; 48% female) bvFTD participants were identified. f-bvFTD cases included 43 with known or presumed chromosome 9 open reading frame 72 (C9orf72) gene expansions, 28 with known or presumed microtubule-associated protein tau (MAPT) mutations, 14 with known progranulin (GRN) mutations, and 14 with a strong family history of FTD but no identified mutation.

RESULTS

Participants with f-bvFTD were younger and had earlier age at onset. s-bvFTD had higher total Neuropsychiatric Inventory Questionnaire (NPI-Q) scores due to more frequent endorsement of depression and irritability.

DISCUSSION

f-bvFTD and s-bvFTD cases are clinically similar, suggesting the generalizability of novel biomarkers, therapies, and clinical tools developed in either form to the other.

The longitudinal evaluation of familial frontotemporal dementia subjects protocol: Framework and methodology

INTRODUCTION

It is important to establish the natural history of familial frontotemporal lobar degeneration (f-FTLD) and provide clinical and biomarker data for planning these studies, particularly in the asymptomatic phase.

METHODS

The Longitudinal Evaluation of Familial Frontotemporal Dementia Subjects protocol was designed to enroll and follow at least 300 subjects for more than at least three annual visits who are members of kindreds with a mutation in one of the three most common f-FTLD genes-microtubule-associated protein tau, progranulin, or chromosome 9 open reading frame 72.

RESULTS

We present the theoretical considerations of f-FTLD and the aims/objectives of this protocol. We also describe the design and methodology for evaluating and rating subjects, in which detailed clinical and neuropsychological assessments are performed, biofluid samples are collected, and magnetic resonance imaging scans are performed using a standard protocol.

DISCUSSION

These data and samples, which are available to interested investigators worldwide, will facilitate planning for upcoming disease-modifying therapeutic trials in f-FTLD.

Nonlinear Z-score modeling for improved detection of cognitive abnormality

INTRODUCTION

Conventional Z-scores are generated by subtracting the mean and dividing by the standard deviation. More recent methods linearly correct for age, sex, and education, so that these "adjusted" Z-scores better represent whether an individual's cognitive performance is abnormal. Extreme negative Z-scores for individuals relative to this normative distribution are considered indicative of cognitive deficiency.

METHODS

In this article, we consider nonlinear shape constrained additive models accounting for age, sex, and education (correcting for nonlinearity). Additional shape constrained additive models account for varying standard deviation of the cognitive scores with age (correcting for heterogeneity of variance).

RESULTS

Corrected Z-scores based on nonlinear shape constrained additive models provide improved adjustment for age, sex, and education, as indicated by higher adjusted-R2.

DISCUSSION

Nonlinearly corrected Z-scores with respect to age, sex, and education with age-varying residual standard deviation allow for improved detection of non-normative extreme cognitive scores.

Oral propranolol in the treatment of proliferating infantile haemangiomas: British Society for Paediatric Dermatology consensus guidelines

BACKGROUND

Infantile haemangiomas (IH) are the most common vascular tumours of infancy. Despite their frequency and potential complications, there are currently no unified U.K. guidelines for the treatment of IH with propranolol. There are still uncertainties and diverse opinions regarding indications, pretreatment investigations, its use in PHACES (posterior fossa malformations-haemangiomas-arterial anomalies-cardiac defects-eye abnormalities-sternal cleft and supraumbilical raphe) syndrome and cessation of treatment.

OBJECTIVES

To provide unified guidelines for the treatment of IH with propranolol.

METHODS

This study used a modified Delphi technique, which involved an international treatment survey, a systematic evidence review of the literature, a face-to-face multidisciplinary panel meeting and anonymous voting.

RESULTS

The expert panel achieved consensus on 47 statements in eight categories, including indications and contraindications for starting propranolol, pretreatment investigations, starting and target dose, monitoring of adverse effects, the use of propranolol in PHACES syndrome and how to stop treatment.

CONCLUSIONS

These consensus guidelines will help to standardize and simplify the treatment of IH with oral propranolol across the U.K. and assist in clinical decision-making.

Systems based analysis of human embryos and gene networks involved in cell lineage allocation

BACKGROUND

Little is understood of the molecular mechanisms involved in the earliest cell fate decision in human development, leading to the establishment of the trophectoderm (TE) and inner cell mass (ICM) stem cell population. Notably, there is a lack of understanding of how transcriptional networks arise during reorganisation of the embryonic genome post-fertilisation.

RESULTS

We identified a hierarchical structure of preimplantation gene network modules around the time of embryonic genome activation (EGA). Using network models along with eukaryotic initiation factor (EIF) and epigenetic-associated gene expression we defined two sets of blastomeres that exhibited diverging tendencies towards ICM or TE. Analysis of the developmental networks demonstrated stage specific EIF expression and revealed that histone modifications may be an important epigenetic regulatory mechanism in preimplantation human embryos. Comparison to published RNAseq data confirmed that during EGA the individual 8-cell blastomeres are transcriptionally primed for the first lineage decision in development towards ICM or TE.

CONCLUSIONS

Using multiple systems biology approaches to compare developmental stages in the early human embryo with single cell transcript data from blastomeres, we have shown that blastomeres considered to be totipotent are not transcriptionally equivalent. Furthermore we have linked the developmental interactome to individual blastomeres and to later cell lineage. This has clinical implications for understanding the impact of fertility treatments and developmental programming of long term health.

Comparison of patient (POEM), observer (EASI, SASSAD, TIS) and corneometry measures of emollient effectiveness in children with eczema: findings from the COMET feasibility trial

BACKGROUND

Eczema affects around 20% of children, but multiple different outcome measures have hampered research into the effectiveness of different treatments.

OBJECTIVES

To compare the change in scores and correlations within and between five measures of eczema severity: Patient-Orientated Eczema Measure (POEM), Eczema Area and Severity Index (EASI), Six Area, Six Sign Atopic Dermatitis (SASSAD), Three Item Severity (TIS) and skin hydration (corneometry).

METHODS

Data from a feasibility trial that randomized young children with eczema to one of four emollients were used. Participants were followed for 3 months (84 days). Descriptive statistics (by emollient over time) and Spearman's correlation coefficients comparing scores at each time point and absolute change (between adjacent time points) for each outcome measure were calculated.

RESULTS

In total, 197 children, mean ± SD age 21·7 ± 12·8 months, were randomized. POEM and TIS appeared to capture a range of eczema severity at baseline, but only POEM had close approximation to normal distribution. Mean POEM, EASI, SASSAD and TIS scores improved month by month, with POEM showing the greatest sensitivity (effect size 0·42). Correlations within POEM, EASI, SASSAD and TIS were moderate to good, decreasing over time. Correlations between measures were strongest for EASI, SASSAD and TIS. By contrast, corneometry scores were more variable, correlated less well over time and were poorly correlated with the other measures.

CONCLUSIONS

Except for corneometry, all measures appear to change in relation to emollient use over time and correlate well with themselves. POEM demonstrated the greatest range of scores at baseline and change in eczema severity over the first 28 days.

Periapical infection may affect birth outcomes via systemic inflammation

OBJECTIVES

Maternal dental periapical infections are associated with preterm birth and intrauterine growth restriction. This study investigates whether the association is mediated through bacterial spread from periapical lesions to placenta (direct pathway) or systemic inflammatory reaction (indirect pathway).

MATERIALS AND METHODS

We compared birth outcomes in Malawian mothers with and without periapical infection. As markers of a direct pathway, we identified placental bacteria using a 16S rDNA approach and assessed histological evidence of inflammation in the placenta and amniotic membranes. We measured C-reactive protein, alpha-1-acid glycoprotein, and salivary cortisol as markers of an indirect pathway. We used regression models to associate the predictor variables with duration of pregnancy and newborn size.

RESULTS

Of 1,024 women, 23.5% had periapical infection. There was no association of periapical infection with either bacterial DNA or histological inflammation in placenta or membranes. Periapical infection was associated with C-reactive protein, alpha-1-acid glycoprotein, and cortisol concentrations in a dose-dependent manner at 36 weeks. Addition of alpha-1-acid glycoprotein or cortisol concentration into regression models attenuated the association between periapical infection and pregnancy outcomes.

CONCLUSION

There was no evidence of direct spread of periapical bacteria to the placenta. Periapical infections and adverse pregnancy outcomes are in part mediated through systemic inflammation.

Is peritoneal dialysis feasible after laparotomy in children? A case-control series to compare outcomes

OBJECTIVES

Peritoneal dialysis (PD) is the modality of choice for children with end-stage renal disease (ESRD) awaiting renal transplant; however, this option is sometimes avoided for those with previous laparotomy. The goal of this study was to compare the outcomes of PD in patients with and without previous laparotomy.

PATIENTS AND METHODS

Twenty-four patients who had been started on peritoneal dialysis were retrospectively analysed. Group LAP consisted of six patients with previous laparotomy, and Group NO-LAP of 18 controls with either retroperitoneal or no abdominal surgery. The percentage of theoretical maximum volume of infusion, time to reach it, complications (infection and drainage difficulties), and number of catheters needed to finish therapy were analysed.

RESULTS

The characteristics of patients and technique of insertion are presented in Table. The percentage of maximum theoretical volume of infusion was similar in both groups. Median of catheter survival was similar in both groups. Complications were divided into malfunction (slow drainage, obstruction or leak) and infection. Incidence of complications per catheter and per month of dialysis was ten times lower in Group NO-LAP. Peritoneal dialysis failed in one patient with recurrent intraperitoneal adhesions after adhesiolysis in Group LAP.

CONCLUSION

Despite a higher incidence of complications (malfunction and infections), PD remains an acceptable option after laparotomy. In this series, it was sufficient in achieving adequate filtration in five patients.

Near miss experiences of transport and recreational cyclists in New South Wales, Australia. Findings from a prospective cohort study

This paper investigates events in which cyclists perceive a cycling crash is narrowly avoided (henceforth, a near miss). A cohort of 2038 adult transport and recreational cyclists from New South Wales (Australia) provided self-reported prospectively collected data from cycling diaries to allow the calculation of an exposure-based rate of near misses and investigation of near miss circumstances. During 25,971days of cycling, 3437 near misses were reported. For a given time cycling, cyclists who rode mainly for transport (compared with those who rode mainly for recreation), and cyclists with less experience (compared to those with more experience) were more likely to report a near miss; older cyclists (60+ years) were less likely to report a near miss than younger cyclists (25-59 years). Where type of near miss was recorded, 72.0% involved motor vehicles, 10.9% involved pedestrians and 6.9% involved other cyclists. Results indicate some similarities between near misses and crashes reported by this cohort during the same reporting period. A bias toward reporting near misses with motor vehicles was suggested, which likely reflects cyclists' perceptions that crashes involving motor vehicles are particularly serious, and highlights their impact on perceived safety. Given the relative rarity of crashes, and the limited breadth and depth of administrative data, collection of near miss data may contribute to our understanding of cycling safety by increasing the volume and detail of information available for analysis. Addressing the causes of near misses may offer an opportunity to improve both perceived and actual safety for cyclists.
