Personalising care for patients: implementing a treatment summary folder following cytoreductive surgery.

BACKGROUND: A patient survey highlighted that patients treated with cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) at one NHS trust lacked confidence with the transition of care between teams. A personalised folder of treatment information was designed and given to patients prior to discharge. AIMS: To obtain patient feedback on the implementation and content of the folder. METHODS: 30 consecutive patients were given the folder at discharge. Participants completed an online questionnaire to determine whether the information in the folder was appropriate, given at the right time in the pathway and enhanced confidence on discharge. FINDINGS: 90% response rate was achieved. Of the respondents, 96% strongly agreed/agreed that the folder was helpful, 4% disagreed; 92% strongly agreed/agreed that the amount of information was right, 8% preferred more information, none less; 74% agreed/strongly agreed that the folder was provided at the right time; 96% said that the content met their expectations. CONCLUSION: Patients treated with CRS and HIPEC have specific needs related to their treatment. Implementation of the patient information folder at discharge increases patient confidence.

The use of clinical photography to aid in the triage of ENT patient referrals.

Waiting lists for Ear, Nose and Throat (ENT) outpatient appointments are currently the longest that they have ever been. The Aneurin Bevan University Health Board has adopted a unique Clinical Photography ENT triage service to tackle this. General Practitioner referrals are triaged by ENT consultants, to identify those patients in whom otoscopic imaging could be used to detect a serious otological condition or to enable virtual management. They are triaged to Clinical Photography, to undergo digital imaging which is reviewed in a virtual clinic alongside the initial referral. 72 patients have completed the pathway, with 51.3% discharged without requirement for face-to-face consultant appointment. 9.7% were upgraded to urgent or 2 week waits. This intervention is predicted to help identify patients on the waiting list with potentially serious disease so that they do not wait excessively, and to reduce waiting times for outpatient appointments in ENT.

Seizure frequency, quality of life, behavior, cognition, and sleep in pediatric patients enrolled in a prospective, open-label clinical study with cannabidiol.

OBJECTIVE: To evaluate the effects of oral pharmacological cannabidiol (CBD) on seizures, side effects, quality of life, behavior, mood, and sleep in children with drug-resistant epilepsy (DRE) during a phase II, prospective, open-label clinical study. METHODS: During a phase II expanded access program (EAP) study to evaluate the safety and efficacy of using cannabidiol (CBD) for the long-term treatment of children with drug-resistant epilepsy, secondary outcome measures were also performed, including quality of life (QOLCE), behavior (aberrant behavior checklist ABC), and sleep (children's sleep habit questionnaire, CSHQ). Participants between the ages of 2 and 16 years of age with drug-resistant epilepsy (n = 35) were included in this EAP. Primary outcomes included change in parent-recorded seizure frequency relative to baseline, as well as the safety and tolerability over the course of 24 months of CBD treatment. Secondary outcomes observed in the first 12 months included changes in child behavior, and cognitive function, and sleep quality. RESULTS: The median change in overall seizure frequency decreased from baseline (n = 33) by -61.3% ([n = 33], Inter Quartile Range (IQR): 43-88%) at month 3, -62.9% at month 6 ([n = 29], IQR: 48-92%), -74.7% at month 12 ([n = 29], IQR: 64-96%), and finally -83.7% ([n = 28], IQR: 68-100%) at the conclusion of 24 months of treatment. Seven (20%) of the 35 patients enrolled withdrew from treatment and observation by month 24: 2 failed inclusion criteria at baseline, 4 due to lack of treatment efficacy, and 1 was lost to follow-up. The 12-month recording of secondary measures revealed a significant improvement in Irritability (-39.4%, [n = 28], ABC), Hyperactivity (-45.4%, [n = 28], ABC), Cognition in Quality of Life (+14.2%, [n = 28], QOLCE), Behavioral function (+14.7%, [n = 28], QOLCE), General Health (+14.7%, [n = 28], QOLCE), Sleep duration (-33.9%, [n = 28], CSHQ), Daytime sleepiness (-23.8%, [n = 28], CSHQ), and nocturnal arousals (-36.2%, [n = 28], CSHQ). SIGNIFICANCE: The results of this phase II open-label study demonstrate that pharmacological CBD significantly reduces seizure frequency, and improves QOL, behavior deficits, and sleep disruption, in children with drug-resistant epilepsy. The results also suggest that CBD is efficacious in controlled seizures over a 2-year period in childhood DRE.

Parent Training for Feeding Problems in Children With Autism Spectrum Disorder: Initial Randomized Trial.

Objective: Many children with autism spectrum disorder (ASD) have feeding and mealtime problems. To address these, we conducted a pilot randomized trial of a new 11-session, individually delivered parent training program that integrated behavioral strategies and nutritional guidance (PT-F). Methods: Forty-two young children (age: 2 to 7-11 years) with ASD and feeding problems were assigned to 11 sessions of PT-F intervention over 20 weeks or a waitlist control. Outcomes included attendance, parent satisfaction, therapist fidelity, and preliminary assessments of child and parent outcomes. Results: Of the 21 PT-F families, attendance was high (85%) as was parent satisfaction (94% would recommend to others). Treatment fidelity was also high (97%-therapist integrity; 94%-parent adherence). Compared with waitlist, children whose parents participated in PT-F showed significantly greater reductions on the two parent-completed primary outcomes (Brief Autism Mealtime Behavior Inventory-Revised; Twald = -2.79; p = .003; About Your Child's Eating; Twald = -3.58; p = .001). On the independent evaluator-completed secondary eating outcome, the Clinical Global Impression-Improvement, 48.8% of the participants in PT-F were rated as "responders" compared with 0% in waitlist (p = .006). General child disruptive behavior outcomes decreased more in PT-F but not significantly. Parent outcomes of caregiver stress showed nonsignificant trends favoring PT-F with moderate to small effect sizes. Conclusions: This trial provides evidence for feasibility, satisfaction, and fidelity of implementation of PT-F for feeding problems in young children with ASD. Feeding outcomes also appeared favorable and lends support for conducting a larger efficacy trial.

The effectiveness of 4 weeks of fundamental movement training on functional movement screen and physiological performance in physically active children.

The effectiveness of fundamental movement training interventions in adolescents is not fully understood. The Functional Movement Screen (FMS) may provide means of evaluating the effectiveness of such programs alongside traditional tests of physiological performance. Twenty-two children completed the FMS, plank, side plank, sit and reach, and multistage fitness test. Participants were pair matched by total FMS score and assigned to control or intervention. The intervention group received a weekly 4 × 30-minute training sessions with an emphasis on movement quality, whereas the control group was involved in generic multisport activity. A smallest worthwhile effect of 0.2 between-participant SDs was set a priori for all measures except total FMS score for which a change of 1 unit was chosen. When compared with the control, our intervention had a likely trivial effect for FMS score (0.2 Arbitrary Units [AU], 90% confidence limits ±1.2 AU), a very likely small beneficial effect for plank score (87 ± 55%), but a possibly small harmful effect for side plank score (-22 ± 49%). A likely trivial effect was observed for the sit and reach test (0.3 ± 15%), whereas the effect of the training intervention on predicted (Equation is included in full-text article.)was unclear (-0.3 ± 11%). Unexpectedly, generic multisport activity enhanced both side plank and sit and reach test performances in the control group. These results demonstrated that short-term interventions might affect specific isolated components of fitness but not FMS performance.

Stratifying risk of malignancy in cystic lateral neck lumps: a multivariant analysis of demographic, radiological and histological investigation factors and the development of a patient-centred risk-predictive tool for malignancy.

BACKGROUND: Management of lateral cystic neck masses with no apparent upper aerodigestive tract primary tumour in adults is controversial. Imaging modalities and fine needle aspiration cytology often struggle to distinguish the presence of malignancy. METHOD: This study entailed a multicentre retrospective review of all patients with isolated lateral cystic neck masses from 2012 to 2018 in three Welsh health boards, utilising demographic data and first-line investigations (ultrasound scanning and fine needle aspiration cytology) to develop an evidence-based predictive tool for risk of malignancy. RESULTS: It was found that 29.1 per cent of cystic lesions were malignant on final histology. Age, male gender, non-benign ultrasound scan findings and fine needle aspiration cytology were significant risk factors on univariate analysis. The final multivariate analysis predicted a risk of malignancy ranging from 2.1 to 65.0 per cent depending on the covariate pattern. Smoking status was non-significant. CONCLUSION: A rigorous, risk-stratified approach to the management of these patients should aid the clinician in minimising morbidity and optimising resources.

Improving Racial and Ethnic Equity in Clinical Trials Enrolling Pregnant and Lactating Individuals.

Racial and ethnic marginalized populations have historically been poorly represented, underrecruited, and underprioritized across clinical trials enrolling pregnant and lactating individuals. The objectives of this review are to describe the current state of racial and ethnic representation in clinical trials enrolling pregnant and lactating individuals and to propose evidence-based tangible solutions to achieving equity in these clinical trials. Despite efforts from federal and local organizations, only marginal progress has been made toward achieving equity in clinical research. This continued limited inclusion and transparency in pregnancy trials exacerbates health disparities, limits the generalizability of research findings, and may heighten the maternal child health crisis in the United States. Racial and ethnic underrepresented communities are willing to participate in research; however, they face unique barriers to access and participation. Multifaceted approaches are required to facilitate the participation of marginalized individuals in clinical trials including partnering with the local community to understand their priorities, needs, and assets; establishing accessible recruitment strategies; creating flexible protocols; supporting participants for their time; and increasing culturally congruent and/or culturally sensitive research staff. This article also highlights exemplars in pregnancy research.

Association of single nucleotide polymorphisms of interleukins-1ß, -6, and -12B with contact lens keratitis susceptibility and severity.

PURPOSE: To investigate whether single nucleotide polymorphisms (SNPs) in interleukin (IL)-1ß, IL-6, and IL-12ß are associated with the susceptibility and severity of contact lens-related keratitis. DESIGN: Retrospective, case control study. PARTICIPANTS: One hundred twelve cases of keratitis and 225 controls were recruited from studies conducted at Moorfields Eye Hospital and in Australia during 2003 through 2005. METHODS: Buccal swab samples were collected on Whatman FTA cards and were mailed by post for analysis. IL-1ß (-31), IL-6 (-174, -572, -597), and IL-12B (3'+1158) genotypes were analyzed with pyrosequencing and analyzed using a regression model for susceptibility (sterile, microbial keratitis, controls) and severity. Statistical significance was set at 0.05. MAIN OUTCOME MEASURES: The relative risk of developing contact lens-related keratitis and more severe forms of the disease based on allele, genotype, and haplotype associations. RESULTS: Carriers of IL-6 SNPs were more likely to experience moderate and severe events compared with those with nonmutated genotypes (-174 heterozygous: odds ratio [OR], 3.1; 95% confidence interval [CI], 1.1-8.3; homozygous: OR, 6.4; 95% CI, 1.4-28.4; -174/-597: OR, 4.1; 95% CI, 1.6-11.0). More severe keratitis and microbial keratitis were less likely to occur in wearers with the nonmutated IL-6 haplotype (severity OR, 0.4 [95% CI, 0.2-0.7]; microbial OR, 0.6 [95% CI, 0.4-0.9]). Wearers carrying an IL-12B SNP had an increased risk of sterile keratitis (OR, 9.7; 95% CI, 1.2-76.9) compared with controls. CONCLUSIONS: The IL-6 SNPs are known to reduce protein expression of this cytokine and thus ocular immune defense, and carriers of these SNPs were more likely to experience more severe and microbial keratitis, suggesting that IL-6 decreases the severity and susceptibility of contact lens-related keratitis. Carriers of a functional SNP of IL-12B that is known to increase IL-12 expression and stability are more likely to experience sterile keratitis, suggesting that this is associated with the intense inflammatory reaction that occurs in this condition.

Comparison of ocular comfort, vision, and SICS during silicone hydrogel contact lens daily wear.

OBJECTIVES: The aim of this study was to investigate the relationship between solution-induced corneal staining (SICS) and silicone hydrogel contact lens comfort and vision. METHODS: A retrospective analysis of a series of open-label studies were conducted with 24 groups of approximately 40 participants, each wearing 1 of 6 silicone hydrogel contact lenses with 1 of 4 lens care products bilaterally for 3 months of daily wear. The presence of SICS and subjective ocular ratings were collected at 2 weeks and at 1 and 3 months. RESULTS: A total of 1,051 participants were enrolled. The participants with SICS rated significantly less favorably than did the participants without SICS for comfort during the day (7.9±1.7 vs. 8.5±1.4, P=0.03), comfort at the end of the day (6.6±2.1 vs. 7.4±1.9, P=0.03), overall dryness (7.4±1.9 vs. 8.0±1.7, P=0.04), dryness at the end of the day (6.7±2.2 vs. 7.5±2.1, P=0.01), feelings of burning and stinging (8.5±2.0 vs. 8.9±1.8, P=0.02), and overall vision (8.2±1.6 vs. 8.7±1.3, P<0.001). CONCLUSIONS: The participants with SICS had lower subjective comfort and vision compared with those who did not experience SICS.

Foraging conditions for breeding penguins improve with distance from colony and progression of the breeding season at the South Orkney Islands.

BACKGROUND: According to central place foraging theory, animals will only increase the distance of their foraging trips if more distant prey patches offer better foraging opportunities. Thus, theory predicts that breeding seabirds in large colonies could create a zone of food depletion around the colony, known as "Ashmole's halo". However, seabirds' decisions to forage at a particular distance are likely also complicated by their breeding stage. After chicks hatch, parents must return frequently to feed their offspring, so may be less likely to visit distant foraging patches, even if their quality is higher. However, the interaction between prey availability, intra-specific competition, and breeding stage on the foraging decisions of seabirds is not well understood. The aim of this study was to address this question in chinstrap penguins Pygoscelis antarcticus breeding at a large colony. In particular, we aimed to investigate how breeding stage affects foraging strategy; whether birds foraging far from the colony visit higher quality patches than available locally; and whether there is evidence for intraspecific competition, indicated by prey depletions near the colony increasing over time, and longer foraging trips. METHODS: We used GPS and temperature-depth recorders to track the foraging movements of 221 chinstrap penguins from 4 sites at the South Orkney Islands during incubation and brood. We identified foraging dives and calculated the index of patch quality based on time allocation during the dive to assess the quality of the foraging patch. RESULTS: We found that chinstrap penguin foraging distance varied between stages, and that trips became shorter as incubation progressed. Although patch quality was lower near the colony than at more distant foraging patches, patch quality near the colony improved over the breeding season. CONCLUSIONS: These results suggest chinstrap penguin foraging strategies are influenced by both breeding stage and prey distribution, and the low patch quality near the colony may be due to a combination of depletion by intraspecific competition but compensated by natural variation in prey. Reduced trip durations towards the end of the incubation period may be due to an increase in food availability, as seabirds time their reproduction so that the period of maximum energy demand in late chick-rearing coincides with maximum resource availability in the environment. This may also explain why patch quality around the colony improved over the breeding season. Overall, our study sheds light on drivers of foraging decisions in colonial seabirds, an important question in foraging ecology.

Wintertime overlaps between female Antarctic fur seals (Arctocephalus gazella) and the krill fishery at South Georgia, South Atlantic.

The diet of Antarctic fur seals (Arctocephalus gazella) at South Georgia is dominated by Antarctic krill (Euphausia superba). During the breeding season, foraging trips by lactating female fur seals are constrained by their need to return to land to provision their pups. Post-breeding, seals disperse in order to feed and recover condition; estimates indicate c.70% of females remain near to South Georgia, whilst others head west towards the Patagonian Shelf or south to the ice-edge. The krill fishery at South Georgia operates only during the winter, providing the potential for fur seal: fishery interaction during these months. Here we use available winter (May to September) tracking data from Platform Terminal Transmitter (PTT) tags deployed on female fur seals at Bird Island, South Georgia. We develop habitat models describing their distribution during the winters of 1999 and 2003 with the aim of visualising and quantifying the degree of spatial overlap between female fur seals and krill harvesting in South Georgia waters. We show that spatial distribution of fur seals around South Georgia is extensive, and that the krill fishery overlaps with small, highly localised areas of available fur seal habitat. From these findings we discuss the implications for management, and future work.

Qualitative analysis of immunization programs with most improved childhood vaccination coverage from 2001 to 2004.

State and urban immunization programs are responsible for the implementation of comprehensive programs to vaccinate populations within their geographic area. Given the variability in immunization coverage rates between geographic areas, the purpose of this two-phase study was to first identify the state and urban areas that achieved the highest increases in coverage, and then those with the highest sustained coverage, between two designated periods, and to interview key program staff members and their community counterparts to capture their perspectives on what factors may have contributed to increasing and sustaining high rates. In this article, we describe phase 1, in which we visited the seven sites that achieved the largest increases in coverage from 2001 to 2004. Results describe outcomes from the 71 semistructured key informant interviews with internal staff and external partners at the site's immunization programs. Interview transcripts were analyzed qualitatively, using a general inductive approach. Common challenges encountered among the seven sites included increasing reluctance among parents and overcoming barriers to accessing care. Common strategies to address these and other challenges included collecting and using data on immunization coverage, developing communication and education efforts, and continuously reaching out and collaborating with immunization partners. Lessons learned from these programs may help inform others who are working to improve childhood immunization delivery and coverage in their own programs.

A qualitative analysis of immunization programs with sustained high coverage, 2000-2005.

Despite record-high immunization coverage nationally, there is considerable variation across state and local immunization programs, which are responsible for the implementation of vaccine recommendations in their jurisdictions. The objectives of this study were to describe activities of state and local immunization programs that sustained high coverage levels across several years and to identify common themes and practical examples for sustaining childhood vaccination coverage rates that could be applied elsewhere. We conducted 95 semi-structured key informant interviews with internal staff members and external partners at the 10 immunization programs with the highest sustained childhood immunization coverage from 2000 to 2005, as measured by the National Immunization Survey. Interview transcripts were analyzed qualitatively using a general inductive approach. Common themes across the 10 programs included maintaining a strong program infrastructure, using available data to drive planning and decision making, a commitment to building and sustaining relationships, and a focus on education and communication. Given the challenges of an increasingly complex immunization system, the lessons learned from these programs may help inform others who are working to improve childhood immunization delivery and coverage in their own programs.

Indications and Patterns of Use for Parenteral Nutrition in Pediatric Oncology.

BACKGROUND: Children with cancer are at risk of treatment related gastrointestinal toxicity and malnutrition. Intestinal dysfunction may preclude or limit use of enteral nutrition, and parenteral nutrition (PN) may be required. Published indications for PN use in children with cancer are generally nonspecific. We sought to describe patterns of use, indications, and frequency of PN prescription in children with cancer and propose indicators to guide appropriate PN use. METHODS: Retrospective chart review of children with cancer receiving inpatient PN in a tertiary referral pediatric hospital over 12 months was performed using electronic medical record search and paper records. Data were summarized using descriptive statistics. RESULTS: PN was prescribed to 88 patients in 111 episodes. Total use (2377 days) represented 24% of annual inpatient days in all children with cancer. Primary clinical indications were mucositis (40%), feed intolerance (29%), postoperative (16%), or "other" (15%), (including nasogastric tube refusal (n = 6)). Patients with hematological cancer had longer median episodes (19 vs 12.5 days) and earlier commencement of PN after diagnosis (50 vs 80 days) than children with nonhematological cancer. Most PN episodes longer than 28 days were in children with hematopoietic stem cell transplant (HSCT). CONCLUSION: Inpatient PN use is common in childhood cancer. Indications include mucositis, feed intolerance, and surgical management. Patterns of use are influenced by cancer diagnosis and treatment, with greater use in children with hematological cancer and HSCT. Improved understanding and specific indications may guide appropriate PN prescription and minimize unnecessary risk, cost, and inconsistency in care.

Nutritional challenges in children with primary immunodeficiencies undergoing hematopoietic stem cell transplant.

Nutritional profile and management of patients with primary immunodeficiencies (PID) undergoing hematopoietic stem cell transplant (HSCT) has not been described in the literature. We aim to report the nutritional challenges and practices peculiar to this population before and after HSCT and suggest clinical pathways for their management. We conducted a single-centre retrospective study. Inclusion criteria were children aged less than 20 years with a diagnosis of PID who have undergone HSCT at the Royal Children's Hospital Melbourne since April 2014 with a minimal follow-up of 1 year. Nutritional parameters were collected in the pre-transplant period, at conditioning, and at 1, 3, 6 and 12 months post-HSCT. Descriptive analysis were used. Between April 2014 and December 2018, 27 children received 31 HSCT. Before transplant, 33% had a weight and/or height ≤ -2 standard deviations (SD). Forty percent required nutritional support before transplant: 33% had enteral nutrition (EN) while 7% required long-term parenteral nutrition (PN) due to intestinal failure. After transplant, although most children were started on EN, 82% required PN with a mean duration of 67 days. Mean time to full oral diet was 154 days. Pre-transplant mean weight and height were -0.57 SD and -0.88 SD respectively. After a decrease in anthropometric parameters the first 3 months post-transplant, progressive catch up was noticeable for weight (-0.27 SD) with no catch up for height at 1 year (-0.93 SD). Our work highlights the nutritional challenges and specificities of children with PID in the peri-transplant period. An approach to nutrition assessment and management in the pre- and post-transplant period is proposed.

Important At-Sea Areas of Colonial Breeding Marine Predators on the Southern Patagonian Shelf.

The Patagonian Shelf Large Marine Ecosystem supports high levels of biodiversity and endemism and is one of the most productive marine ecosystems in the world. Despite the important role marine predators play in structuring the ecosystems, areas of high diversity where multiple predators congregate remains poorly known on the Patagonian Shelf. Here, we used biotelemetry and biologging tags to track the movements of six seabird species and three pinniped species breeding at the Falkland Islands. Using Generalized Additive Models, we then modelled these animals' use of space as functions of dynamic and static environmental indices that described their habitat. Based on these models, we mapped the predicted distribution of animals from both sampled and unsampled colonies and thereby identified areas where multiple species were likely to overlap at sea. Maximum foraging trip distance ranged from 79 to 1,325 km. However, most of the 1,891 foraging trips by 686 animals were restricted to the Patagonian Shelf and shelf slope, which highlighted a preference for these habitats. Of the seven candidate explanatory covariates used to predict distribution, distance from the colony was retained in models for all species and negatively affected the probability of occurrence. Predicted overlap among species was highest on the Patagonian Shelf around the Falkland Islands and the Burdwood Bank. The predicted area of overlap is consistent with areas that are also important habitat for marine predators migrating from distant breeding locations. Our findings provide comprehensive multi-species predictions for some of the largest marine predator populations on the Patagonian Shelf, which will contribute to future marine spatial planning initiatives. Crucially, our findings highlight that spatially explicit conservation measures are likely to benefit multiple species, while threats are likely to impact multiple species.

Exploring sleep quality of young children with autism spectrum disorder and disruptive behaviors.

BACKGROUND AND PURPOSE: Sleep disturbances in autism spectrum disorder (ASD) are common and may impair daytime functioning as well as add to parental burden. In this well characterized sample of young children with ASD and disruptive behaviors, we examine the association of age and IQ in sleep disturbances using the Child Sleep Habits Questionnaire modified for ASD (CSHQ-ASD). We also test whether children with poor sleep have greater daytime behavioral problems than those with better sleep. Finally, we examine whether parental stress is higher in children with greater disruptive behaviors and sleep disturbances. PARTICIPANTS AND METHODS: One hundred and seventy-seven children with complete data out of 180 (mean age 4.7) with ASD participated in a randomized clinical trial. Parents completed the CSHQ-ASD and several other measures at study enrollment. The sample was divided into "poor sleepers" (upper quartile on the total score of the CSHQ-ASD) and "good sleepers" (lower quartile) for comparisons. Analyses were conducted to evaluate group differences on age, IQ, daytime disruptive behavior, social disability and parental stress. RESULTS: The two groups of young children with ASD, good sleepers versus poor sleepers, were not different on age or cognitive level. Children in the poor sleeping group had significantly higher daytime behavioral problems including irritability, hyperactivity, social withdrawal and stereotypical behaviors. Parents in this group reported significantly higher levels of stress. CONCLUSIONS: The finding of no age difference between good and poor sleepers in young children with ASD and disruptive behaviors suggests that sleep problems are unlikely to resolve as might be expected in typically developing children. Likewise, the good and poor sleepers did not significantly differ in IQ. These findings add strong support for the need to screen for sleep disturbances in all children with ASD, regardless of age and cognitive level. Poor sleepers exhibited significantly greater daytime behavioral problems and parents of children in this group reported significantly higher levels of stress. Above and beyond the co-occurring disruptive behavior, poor sleep quality appears to pose substantial additive burden on child and parents.

Identification of marine Important Bird and Biodiversity Areas for penguins around the South Shetland Islands and South Orkney Islands.

AIM: To provide a method of analyzing penguin tracking data to identify priority at-sea areas for seabird conservation (marine IBAs), based on pre-existing approaches for flying seabirds but revised according to the specific ecology of Pygoscelis penguin species. LOCATION: Waters around the Antarctic Peninsula, South Shetland, and South Orkney archipelagos (FAO Subareas 48.1 and 48.2). METHODS: We made key improvements to the pre-existing protocol for identifying marine IBAs that include refining the track interpolation method and revision of parameters for the kernel analysis (smoothing factor and utilization distribution) using sensitivity tests. We applied the revised method to 24 datasets of tracking data on penguins (three species, seven colonies, and three different breeding stages-incubation, brood, and crèche). RESULTS: We identified five new marine IBAs for seabirds in the study area, estimated to hold ca. 600,000 adult penguins. MAIN CONCLUSIONS: The results demonstrate the efficacy of a new method for the designation of a network of marine IBAs in Antarctic waters for penguins based on tracking data, which can contribute to an evidence-based, precautionary, management framework for krill fisheries.
