RESUMO
This study presents an updated analysis spanning over two decades (1999-2023) of climate, water quality, and operational data from two drinking water facilities in Atlantic Canada that previously experienced gradual increases in the natural organic matter (NOM) concentration and brownification. The goal was to assess the impact of recent extreme weather events on acute NOM concentration increases and drinking water treatment processes. In 2023, a dry spring combined with a warm and wet summer caused NOM in the water supplies to increase by >67% (as measured by color). To mitigate increased NOM concentration, the alum dose nearly doubled in 2023 compared to that in 2022. Disinfection byproducts were elevated following the event but remained within the compliance levels. From 1999 to 2023, the two plants responded to gradual climate change impacts and brownification, with alum dose increases of between 4.1 and 8.3 times. Equivalent CO2 emissions were estimated for alum usage, which increased by 3 to 7-fold in 2023 compared to when the plants were commissioned decades prior. The plants were not only adversely impacted by climate change but also contributed to the global CO2 burden. Thus, a paradigm shift toward sustainable alternatives for NOM removal is required in the water sector, and climate change adaptation and mitigation principles are urgently needed.

Surgical complications are inevitable in any surgical subspecialty. Throughout the years, many classification systems have been developed to better understand and report such complications. The aim of this systematic review is to investigate the variability and frequency of reporting terms used to describe adverse events and complications in hallux valgus reconstruction. We hypothesized that the terms used would be highly inconsistent, which further promotes a need for a standardized terminology reporting system. Studies related to hallux valgus reconstruction outcomes that met our predetermined inclusion criteria were investigated to identify and report the related adverse terms and complications. Adverse terms and complications were grouped into 9 categories. Of the 142 studies included, 376 distinct terms that described adverse events or complications related to hallux valgus reconstruction were identified. Of these, 73.4% (276/376) were mentioned only once in their respective studies. Five of 376 terms were mentioned in at least 25% of the papers, and only 2 of 376 were mentioned in at least 50%. The most frequently reported adverse events were "Recurrence," mentioned in 77 of 142 studies (54%), followed by "Nonunion," mentioned in 76 of 142 studies (53%). The most reported category was "Bone/Joint" with 135 related terms, mentioned in 135 of 376 of the papers (95.1%). The terminology used in reporting adverse events and complications in surgical hallux valgus correction was highly inconsistent and variable. This represents yet another barrier in accurate reporting of these terms, and subsequently a difficult analysis of the outcomes related to hallux valgus reconstruction. To overcome these challenges, we suggest developing a standardized terminology reporting system.Levels of Evidence: Level III; systematic review of Level III studies and above.
RESUMO
Cyanotoxins pose significant human health risks, but traditional monitoring approaches can be expensive, time consuming, and require analytical equipment or expertise that may not be readily available. Quantitative polymerase chain reaction (qPCR) is becoming an increasingly common monitoring strategy as detection of the genes responsible for cyanotoxin synthesis can be used as an early warning signal. Here we tested passive sampling of cyanobacterial DNA as an alternative to grab sampling in a freshwater drinking supply lake with a known history of microcystin-LR. DNA extracted from grab and passive samples was analyzed via a multiplex qPCR assay that included gene targets for four common cyanotoxins. Passive samples captured similar trends in total cyanobacteria and the mcyE/ndaF gene responsible for microcystin production when compared to traditional grab samples. Passive samples also detected genes associated with the production of cylindrospermopsin and saxitoxin that were not detected in grab samples. This sampling approach proved a viable alternative to grab sampling when used as an early warning monitoring tool. In addition to the logistical benefits of passive sampling, the detection of gene targets not detected by grab samples indicates that passive sampling may allow for a more complete profile of potential cyanotoxin risk.

Reduced atmospheric acid deposition has given rise to recovery from acidification - defined as increasing pH, acid neutralization capacity (ANC), or alkalinity in surface waters. Strong evidence of recovery has been reported across North America and Europe, driving chemical responses. The primary chemical responses identified in this review were increasing concentration and changing character of natural organic matter (NOM) towards predominantly hydrophobic nature. The concentration of NOM also influenced trace metal cycling as many browning surface waters also reported increases in Fe and Al. Further, climate change and other factors (e.g., changing land use) act in concert with reductions in atmospheric deposition to contribute to widespread browning and will have a more pronounced effect as deposition stabilizes. The observed water quality trends have presented challenges for drinking water treatment (e.g., increased chemical dosing, poor filter operations, formation of disinfection by-products) and many facilities may be under designed as a result. This comprehensive review has identified key research areas to be addressed, including 1) a need for comprehensive monitoring programs (e.g., larger timescales; consistency in measurements) to assess climate change impacts on recovery responses and NOM dynamics, and 2) a better understanding of drinking water treatment vulnerabilities and the transition towards robust treatment technologies and solutions that can adapt to climate change and other drivers of changing water quality.

PURPOSE: Adolescent and young adult (AYA) cancer survivors experience treatment-related late effects so guidelines recommend providing a treatment summary, yearly follow-up, and risk-adapted testing. AYA survivors' knowledge of surveillance follow-up was studied. RESULTS: Survey responses for 73 AYAs were stratified: low (0 to 1 correct; n=18; 24.7%) versus high knowledge (2 to 4 correct; n=55; 75.3%) of their required testing. Patient-reported Outcomes Measurement Information System (PROMIS) scores fell within average ranges for participant age ( T -scores: 52.4 for physical function, 49.3 for anxiety, 46.3 for depression, and 44.7 for fatigue). Younger age at survivorship visit was a significant predictors of improved knowledge scores. CONCLUSION: Despite attendance at a survivorship clinic, minority of participants (9.5%) demonstrated complete knowledge of surveillance testing needs. Most survivors are aware of some of their surveillance needs. PROMIS scores were not associated with surveillance knowledge.

The development of immune checkpoint inhibitors (ICIs) has revolutionized cancer treatment, with agents such as nivolumab, pembrolizumab, and cemiplimab targeting programmed cell death protein-1 (PD-1) and durvalumab, avelumab, and atezolizumab targeting PD-ligand 1 (PD-L1). Ipilimumab targets cytotoxic T lymphocyte-associated antigen-4 (CTLA-4). These inhibitors have shown remarkable efficacy in melanoma, lung cancer, urothelial cancer, and a variety of solid tumors, either as single agents or in combination with other anticancer modalities. Additional indications are continuing to evolve. Checkpoint inhibitors are associated with less toxicity when compared to chemotherapy. These agents enhance the antitumor immune response and produce side- effects known as immune-related adverse events (irAEs). Although the incidence of immune checkpoint inhibitor pneumonitis (ICI-Pneumonitis) is relatively low, this complication is likely to cause the delay or cessation of immunotherapy and, in severe cases, may be associated with treatment-related mortality. The primary mechanism of ICI-Pneumonitis remains unclear, but it is believed to be associated with the immune dysregulation caused by ICIs. The development of irAEs may be related to increased T cell activity against cross-antigens expressed in tumor and normal tissues. Treatment with ICIs is associated with an increased number of activated alveolar T cells and reduced activity of the anti-inflammatory Treg phenotype, leading to dysregulation of T cell activity. This review discusses the pathogenesis of alveolar pneumonitis and the incidence, diagnosis, and clinical management of pulmonary toxicity, as well as the pulmonary complications of ICIs, either as monotherapy or in combination with other anticancer modalities, such as thoracic radiotherapy.
RESUMO
Previous research suggests that dating, intimate partner, and sexual violence victimization throughout the lifespan are predictive of numerous adverse health outcomes including addictive behaviors, psychopathology, and physical health symptoms. Self-medication hypotheses posit that victims may drink heavily, use substances, or rely on food to cope with negative affect and psychological symptoms. We examined a self-medication hypothesis-driven model linking dating and sexual violence victimization with food addiction symptoms through their relationships with emotion regulation, impulsivity, and loss-of-control eating in a sample of 313 single, non-treatment-engaged, college student women aged 18-25 years old enrolled in a minority serving, urban university. Participants completed an online survey with measures of dating and sexual violence victimization since age 14 years, emotion regulation, impulsivity, loss-of-control eating, and food addiction symptoms. Seventy-nine percent of participants reported experiencing some form of intimate partner violence victimization. Using path analyses, we found some support for our model, as well as significant, positive, direct pathways from victimization to loss-of-control eating and food addiction symptoms. Clinicians and policy makers should incorporate these findings into practice by honoring the experiences of past victimizations in current health behaviors and by utilizing trauma-informed care practices. To extend this study's findings, researchers should examine the role of trauma-informed interventions targeting emotional regulation and impulsivity to decrease loss-of-control eating and food addiction symptoms.
RESUMO
OBJECTIVES: In this study, we examined the indirect effects of anxiety on glycated hemoglobin (A1C) via automatic negative thinking and diabetes distress among adolescents with type 1 diabetes (T1D) during the follow-up interval of a randomized controlled trial of an intervention targeting resilience promotion/depression prevention. METHODS: Adolescents (N=264) participating in the Supporting Teen Problem Solving clinical trial were included and assessed at 8, 12, 16 and 28 months postbaseline. A serial, double-mediation model was used to examine path effects from anxiety to A1C through automatic negative thinking, through diabetes distress and through both automatic negative thinking and diabetes distress. Relevant demographic and clinical covariates were included. RESULTS: Anxiety significantly predicted increases in both automatic negative thinking and diabetes distress. Automatic negative thinking was not found to mediate the association between anxiety and A1C, but diabetes distress did mediate the association. The double-mediation path through automatic negative thinking and diabetes distress together was significant. The indirect effect of anxiety on A1C through diabetes distress was significant and greater than the indirect effect of the double-mediator path. Anxiety did not predict A1C independent of its effects on automatic negative thinking and diabetes distress. Inclusion of demographic covariates did not substantively change the results. CONCLUSIONS: Analyses suggest that automatic negative thinking and diabetes distress mediate the relationship between anxiety and A1C among adolescents with T1D. Diabetes distress appears to be a robust factor linking anxiety to A1C. Diabetes distress should be further examined as a mediator of glycemic variability in anxious youth with T1D.

This article offers a systematic review of the literature on psychosocial aspects of technology use in children and adolescents with type 1 diabetes and their families, searching for relevant articles published the past 5 years. Topics included continuous subcutaneous insulin infusion, continuous glucose monitoring, predictive low-glucose suspend, and artificial pancreas systems. The review indicates there are positive and negative psychosocial aspects to diabetes technology use among youth and their families. Although consistent findings were revealed, contradictions exist. Discussed are recommendations for future research and implications for how health care providers can collaborate with families to discuss and manage diabetes technology.

OBJECTIVE: Youth with chronic illness are at higher risk for psychosocial difficulties, leading to a call for screening via patient-reported outcomes (PROs). The purpose of the current review is to summarize PRO implementation in pediatric medical specialty settings. A literature review of PRO implementation in these settings, conceptual issues, value and approach, legal and ethical concerns, as well as a case example of PROA in type 1 diabetes are presented. METHODS: A systematic review was conducted to identify relevant articles published since the most recent Journal of Pediatric Psychology Special Issue on Evidence-Based Assessment in Pediatric Psychology (2008). RESULTS: Thirty-two articles were identified and reviewed. The majority of studies reported that PROA was feasible, did not disrupt clinic flow, identified psychosocial issues warranting intervention, and was acceptable to families and providers. Response to elevated scores and impact on behavioral health referrals varied. CONCLUSION: While many evidenced-based assessment measures are well-validated within pediatric chronic illness groups, the literature regarding implementation of PROs is still emerging. Research findings are promising, with PROs being feasible, acceptable, and leading to increased discussion of psychosocial issues when integrated into pediatric medical settings. Additional research is needed to evaluate the longitudinal impact of PROs and the optimal manner of responding to assessment data, particularly when clinically-elevated. Ultimately, identifying psychosocial issues in pediatric medical settings can promote optimal health and well-being of youth with chronic illness and their families.

OBJECTIVE: Limited research has examined the impact of technology on intimacy and relationships among individuals with type 1 diabetes (T1D). The current study examined the experiences of individuals with T1D and their partners and evaluated the expectations for how advances in technology such as automated insulin delivery systems may impact physical intimacy. METHOD: The Insulin Delivery Systems: Perceptions, Ideas, Reflections and Expectations (INSPIRE) study is a multisite study examining expectations for automated insulin delivery systems among adults and youth with T1D as well as partners and caregivers. For the current analysis, data regarding the impact of diabetes on relationship intimacy were extracted from focus groups or individual semistructured interviews with adults with T1D (n = 113) and partners of individuals with T1D (n = 55). RESULTS: Three independent coders conducted thematic analysis utilizing NVivo software. Two primary themes were identified: vulnerability in romantic relationships because of managing diabetes and the unique challenges of physical intimacy because of the use of diabetes technology. CONCLUSIONS: Participants expressed the hope that diabetes technology, and automated insulin delivery systems in particular, will offer opportunities for flexibility in their diabetes management. These options may decrease their sense of vulnerability through provision of greater control over diabetes management and when/whether to disclose diabetes, minimizing discomforts in the context of sexual intimacy, and reduction of fear about diabetes complications. Patient-reported outcomes and expectations for diabetes technology should be incorporated into patient-provider conversations about sensitive issues.

PURPOSE: This study aimed to elucidate experiences and preferences for survivorship care delivery among adolescent and young adult (AYA) childhood cancer survivors who experienced healthcare transitions. METHODS: Eight focus groups were conducted with two groups of AYA survivors and their parents: (1) those who recently completed cancer treatment and are beginning follow-up care and (2) those who disengaged in follow-up care after the transition from pediatric to adult survivorship clinics. Interviewers used a structured interview guide that contained questions about perceptions and preferences for survivorship care models, resources, and tools (e.g., a survivorship care plan). We employed directed content analysis techniques to identify and organize relevant themes. RESULTS: Results of this study support six primary themes for optimizing survivorship care models for AYA: (1) improve knowledge of late effects and need for LTFU; (2) provide supportive services that help to address fear and uncertainty about health; (3) adapt survivorship care to be consistent with AYA developmental factors; (4) increase support surrounding healthcare transitions; (5) improve survivorship care communication and coordination between patients and families, and between providers; and (6) incorporate digital health tools. CONCLUSIONS: These groups represent vulnerable patient populations in AYA survivorship care and their perspectives highlight potential clinical and research priorities for enhancing long-term care models. IMPLICATIONS FOR CANCER SURVIVORS: Elucidating AYA and parent recommendations for survivorship care delivery can help to promote continuous engagement in care, target unmet needs, and promote health through survivorship models that are deemed acceptable to both patients and families.

Phantom limb pain (PLP) following amputation, which is experienced by the vast majority of amputees, has been reported to be relieved with daily sessions of mirror therapy. During each session, a mirror is used to view the reflected image of the intact limb moving, providing visual feedback consistent with the movement of the missing/phantom limb. To investigate potential neural correlates of the treatment effect, we measured brain responses in volunteers with unilateral leg amputation using functional magnetic resonance imaging (fMRI) during a four-week course of mirror therapy. Mirror therapy commenced immediately following baseline scans, which were repeated after approximately two and four week intervals. We focused on responses in the region of sensorimotor cortex corresponding to primary somatosensory and motor representations of the missing leg. At baseline, prior to starting therapy, we found a strong and unexpected response in sensorimotor cortex of amputees to visually presented images of limbs. This response was stronger for images of feet compared to hands and there was no such response in matched controls. Further, this response to visually presented limbs was no longer present at the end of the four week mirror therapy treatment, when perceived phantom limb pain was also reduced. A similar pattern of results was also observed in extrastriate and parietal regions typically responsive to viewing hand actions, but not in regions corresponding to secondary somatosensory cortex. Finally, there was a significant correlation between initial visual responsiveness in sensorimotor cortex and reduction in PLP suggesting a potential marker for predicting efficacy of mirror therapy. Thus, enhanced visual responsiveness in sensorimotor cortex is associated with PLP and modulated over the course of mirror therapy.

OBJECTIVE: Children with type 1 diabetes and their parents face daily self-care demands, leading to diabetes-specific emotional distress. A standardized measure of diabetes distress can guide clinical care and prevent negative outcomes. METHODS: This study evaluated the psychometric properties of child- and parent-report measures of the Problem Areas in Diabetes Scale, adapted for children ages 8-12 (PAID-C) and their parents (P-PAID-C). Participants were from 42 diabetes camps in the United States. Children (N = 804; mean age = 10.3 ± 1.1) and parents (N = 968) completed measures of diabetes distress, diabetes-related strengths, and self-care skills. Half of the sample was used for exploratory factor analyses (EFA) with direct oblimin rotation and the other half for confirmatory factor analyses (CFAs). RESULTS: For the PAID-C, EFA and CFAs supported an 11-item two-factor measure, Cronbach's α = .91, accounting for 54.6% of the variance. For the P-PAID-C, analyses resulted in a 16-item measure, Cronbach's α = .92, accounting for 51.9% of the variance. PAID-C and P-PAID-C scores were positively correlated with HbA1c (rchild = .08, p = .04; rparent = .18, p < .001), and negatively correlated with diabetes-related strengths (rchild = -.38, p < .001, rparent = -.29, p < .001) and parent report of child self-care skills (rparent = -.13, p < .001; rchild = -0.07, p = ns). CONCLUSIONS: Initial psychometrics suggest that the PAID-C and P-PAID-C reliably and validly capture diabetes-specific emotional distress for children and their parents. Associations with glycemic control, self-care, and diabetes strengths demonstrate criterion validity. Both measures have potential applications for routine, clinic-based assessments of diabetes distress and may guide clinical decision-making.

Bone marrow adipose tissue (BMAT) is preserved or increased in states of caloric restriction. Similarly, we found that BMAT in the tail vertebrae, but not the red marrow in the tibia, resists loss of neutral lipid with acute, 48-hour fasting in rats. The mechanisms underlying this phenomenon and its seemingly distinct regulation from peripheral white adipose tissue (WAT) remain unknown. To test the role of ß-adrenergic stimulation, a major regulator of adipose tissue lipolysis, we examined the responses of BMAT to ß-adrenergic agonists. Relative to inguinal WAT, BMAT had reduced phosphorylation of hormone sensitive lipase (HSL) after treatment with pan-ß-adrenergic agonist isoproterenol. Phosphorylation of HSL in response to ß3-adrenergic agonist CL316,243 was decreased by an additional ~90% (distal tibia BMAT) or could not be detected (tail vertebrae). Ex vivo, adrenergic stimulation of lipolysis in purified BMAT adipocytes was also substantially less than iWAT adipocytes and had site-specific properties. Specifically, regulated bone marrow adipocytes (rBMAs) from proximal tibia and femur underwent lipolysis in response to both CL316,243 and forskolin, while constitutive BMAs from the tail responded only to forskolin. This occurred independently of changes in gene expression of ß-adrenergic receptors, which were similar between adipocytes from iWAT and BMAT, and could not be explained by defective coupling of ß-adrenergic receptors to lipolytic machinery through caveolin 1. Specifically, we found that whereas caveolin 1 was necessary to mediate maximal stimulation of lipolysis in iWAT, overexpression of caveolin 1 was insufficient to rescue impaired BMAT signaling. Lastly, we tested the ability of BMAT to respond to 72-hour treatment with CL316,243 in vivo. This was sufficient to cause beiging of iWAT adipocytes and a decrease in iWAT adipocyte cell size. By contrast, adipocyte size in the tail BMAT and distal tibia remained unchanged. However, within the distal femur, we identified a subpopulation of BMAT adipocytes that underwent lipid droplet remodeling. This response was more pronounced in females than in males and resembled lipolysis-induced lipid partitioning rather than traditional beiging. In summary, BMAT has the capacity to respond to ß-adrenergic stimuli, however, its responses are muted and BMAT generally resists lipid hydrolysis and remodeling relative to iWAT. This resistance is more pronounced in distal regions of the skeleton where the BMAT adipocytes are larger with little intervening hematopoiesis, suggesting that there may be a role for both cell-autonomous and microenvironmental determinants. Resistance to ß-adrenergic stimuli further separates BMAT from known regulators of energy partitioning and contributes to our understanding of why BMAT is preserved in states of fasting and caloric restriction.

Objectives: Methods for developing mobile health (mHealth) interventions are not well described. To guide the development of future mHealth interventions, we describe the application of the agile science framework to iteratively develop a mHealth intervention for adolescent and young adult (AYA) survivors of childhood cancer. Methods: We created the AYA STEPS mobile app (AYA Self-management via Texting, Education, and Plans for Survivorship) by modifying and integrating two existing programs: an online survivorship care plan (SCP) generator and a text messaging self-management intervention for AYA off treatment. The iterative development process involved three stages of agile science: 1) Formative work, 2) Obtaining feedback about the first AYA STEPS prototype, and 3) Pilot testing and finalization of a prototype. We determined preferences of AYA stakeholders as well as discovered and addressed technology problems prior to beginning a subsequent randomized controlled trial. Results: AYA survivors reported that the app and the embedded tailored messages related to their health and SCP, were easy to use and generally satisfying and beneficial. Usage data supported that AYA were engaged in the app. Technology glitches were discovered in the pilot and addressed. Conclusions: The iterative development of AYA STEPS was essential for creating a consistent and acceptable end user experience. This study serves as one example of how behavioral scientists may apply agile science to their own mHealth research.
RESUMO
BACKGROUND: Adherence to illness self-management among youth with sickle cell disease (SCD) positively impacts health outcomes and decreases overall healthcare costs. Despite this, children with SCD face several barriers to adherence, with adherence rates that remain moderate to low. The current feasibility study examined the Intensive Training Program (ITP), a mobile health (mHealth) intervention for youth with SCD designed to promote disease knowledge, adherence, and patient-provider communication. PROCEDURE: Youth with SCD prescribed hydroxyurea between ages 7-18 completed baseline disease knowledge and psychosocial assessments and then were provided with the ITP app. Youth participated in the 90-day ITP, during which they completed three education modules, tracked adherence through daily self-recorded videos on the app, and received video messages from providers. Participants completed poststudy knowledge, psychosocial, and feasibility questionnaires. Medication possession ratio (MPR) was obtained via pharmacy-refill rates. RESULTS: Thirty-two youths (mean age = 13.0 years) participated, with an average adherence tracking rate of 0.6 (standard deviation = 0.34). All participants demonstrated increased MPR (0.57-0.74, P < 0.001, d = 0.75) and disease knowledge (59.6-88.6%, P < 0.001). There was variable engagement in the ITP; completers demonstrated significantly better SCD-related functioning (P < 0.05), higher parent-reported treatment functioning (P < 0.05), and lower pain impact than noncompleters of the ITP (P < 0.05). CONCLUSIONS: Results support the ITP can feasibly be implemented to promote adherence among youth with SCD. All participants demonstrated increased adherence and disease knowledge. However, there was variable engagement and only intervention completers showed improvements in psychosocial outcomes. Further research is needed to evaluate long-term outcomes and ways to promote engagement in mHealth interventions among the youth.

PURPOSE OF REVIEW: A systematic review was conducted of family-based interventions to improve glycemic control, adherence, and psychosocial outcomes in children and adolescents with type 1 diabetes (T1D). Electronic databases were searched for randomized controlled trials (RCTs) published since the seminal Diabetes Control and Compliance Trial (DCCT). Interventions are summarized and findings reviewed to help guide clinical practice and future research. RECENT FINDINGS: Twenty-five RCTs are reviewed. The majority of studies (n = 15) focused on interventions targeting both children and adolescents and their caregivers and were delivered in diabetes clinics, outpatient settings, mental health clinics, or participants' homes. Family-based interventions for youth with T1D appear effective at improving diabetes and family-centered outcomes. Additional research is needed to examine the pathways to improvement in glycemic control, as outcomes were mixed. Future research should also involve measures beyond HbA1c given new markers for sustained health improvement and outcomes are being explored.

Iron chelation therapy can prevent iron overload for pediatric patients with sickle cell disease and ß-thalassemia major; however, adherence is suboptimal. Therefore, we developed an intensive training program (ITP), to improve medication management and disease knowledge. The objectives were to determine feasibility of the ITP and its preliminary impact on adherence, disease knowledge, and health outcomes. Pediatric patients were recruited to participate in the ITP over a 90-day period and were followed for 6 months. The ITP consisted of 3 components: (1) provider-led education modules; (2) patient recording daily videos of at-home medication administration; and (3) provider feedback through video messages through the ITP app. Eleven patients participated (mean=12.4 y). Initially, patients endorsed high satisfaction and ease of use and tracked their medication usage 81% (24 out of 30) of days. At 90 days, adherence rates remained consistent (80%) and disease knowledge retention was high (96%). At 6 months, participants exhibited a clinically relevant decrease in serum ferritin, which trended toward statistical significance (P=0.068). Medication possession ratio did not significantly increase (0.65 to 0.72; not significant). The mobile ITP was feasibly implemented in a clinical setting; in addition, high levels of compliance, disease knowledge retention, and acceptance encourage larger studies evaluating mobile health technology to improve child health parameters.

Glucocorticoid (GC) hormones promote basic life processes, regulate life-history transitions, and help individuals cope with challenges and stressors, thereby playing an important fitness role. Here, we review recent evidence for several factors that influence plasma concentrations of corticosterone (CORT), the main GC in tuatara (Sphenodon punctatus), and discuss the application of CORT as a physiological tool to monitor conservation efforts. Observational studies show an association between CORT concentrations and seasonal reproductive activity, ambient temperature, and ecological habitat parameters (including presence of rats/seabird abundance, sex-ratio, and genetic diversity), and experimental studies show a positive influence of acute temperature increase on the CORT response. Recently, CORT physiology has been applied as a monitoring tool in tuatara translocation programmes. No signs of chronic stress in CORT profiles were observed during standard short- and long-term translocation and rat eradication procedures, giving confidence that current conservation efforts are supportive in population recovery. These results provide a foundation for comparative understanding of stress physiology in reptiles, and will be critical for managing future population viability of tuatara in a changing environment.
