Abstract
Significant health disparities exist in relation to pathogenic variants in BRCA1/2. This study aimed to better understand the barriers and facilitators to BRCA1/2 genetic testing and intrafamilial communication of risk in racially and ethnically diverse individuals. We conducted qualitative interviews with non-Hispanic White (n = 11) and Black, Indigenous, People of Color (BIPOC) individuals (n = 14) who underwent testing for pathogenic BRCA1/2 variants. We employed template analysis, case study analysis, and comparative case study analysis to examine healthcare experiences related to genetic testing as well as intrafamilial communication of risk. Applying an intersectional lens, we sought to inform more person-centered approaches to precision healthcare and help dismantle disparities in genomic healthcare. Template analysis revealed salient factors at the individual (psychosocial well-being), interpersonal/familial, and healthcare system levels. A two-part case study analysis provided insights into how race/ethnicity, cultural norms, and socioeconomic status interact with systemic and structural inequities to compound disparities. These findings underscore the need for person-centered, tailored, and culturally sensitive approaches to understanding and addressing the complexities surrounding testing and the communication of BRCA risk. Applying an intersectional lens can inform more person-centered approaches to precision healthcare and may help to surmount existing disparities.

Abstract
BACKGROUND Although some male patients with congenital hypogonadotropic hypogonadism (CHH) undergo spontaneous reversal following treatment, predictors of reversal remain elusive. We aimed to assemble the largest cohort of male patients with CHH reversal to date and identify distinct classes of reversal. METHODS This multicentre cross-sectional study was conducted in six international CHH referral centres in Brazil, Finland, France, Italy, the UK, and the USA. Adult men with CHH (ie, absent or incomplete spontaneous puberty by age 18 years, low serum testosterone concentrations, and no identifiable cause of hypothalamic-pituitary-gonadal [HPG] axis dysfunction) were eligible for inclusion. CHH reversal was defined as spontaneous recovery of HPG axis function off treatment. Centres provided common data elements on patient phenotype, clinical assessment, and genetics using a structured, harmonised data collection form developed by COST Action BM1105. Latent class mixture modelling (LCMM) was applied to establish whether at least two distinct classes of reversal could be identified and differentially predicted, and results were compared with a cohort of patients without CHH reversal to identify potential predictors of reversal. The primary outcome was the presence of at least two distinct classes of reversal. FINDINGS A total of 87 male patients with CHH reversal and 108 without CHH reversal were included in the analyses. LCMM identified two distinct reversal classes (75 [86%] in class 1 and 12 [14%] in class 2) on the basis of mean testicular volume, micropenis, and serum follicle-stimulating hormone (FSH) concentration. Classification probabilities were robust (0·998 for class 1 and 0·838 for class 2) and modelling uncertainty was low (entropy 0·90). Compared with class 1, patients in class 2 had significantly larger testicular volume (p<0·0001), no micropenis, and higher serum FSH concentrations (p=0·041), consistent with the Pasqualini syndrome (fertile eunuch) subtype of CHH. Patients without CHH reversal were more likely to have anosmia (p=0·016), cryptorchidism (p=0·0012), complete absence of puberty (testicular volume <4 cm³; p=0·0016), and two or more rare genetic variants (ie, oligogenicity; p=0·0001). Among patients who underwent genetic testing, no patients (of 75) with CHH reversal had a rare pathogenic ANOS1 variant compared with ten (11%) of 95 patients without CHH reversal. Individuals with CHH reversal had a significantly higher rate of rare variants in GNRHR than did those without reversal (nine [12%] of 75 vs three [3%] of 95; p=0·025). INTERPRETATION Applying LCMM to a large cohort of male patients with CHH reversal uncovered two distinct classes of reversal. Genetic investigation combined with careful clinical phenotyping could help surveillance of reversal after withdrawing treatment, representing the first tailored management approach for male patients with this rare endocrine disorder.

Abstract
Introduction: Efforts are needed across disciplines to close disparities in genomic healthcare. Nurses are the most numerous trained healthcare professionals worldwide and can play a key role in addressing disparities across the continuum of care. ACCESS is an empirically-based theoretical framework to guide clinical practice in order to ameliorate genomic disparities. Methods: The framework was developed by the International Nursing CASCADE Consortium based on evidence collected between 2005 and 2023 from individuals and families of various ethnic backgrounds, with diverse hereditary conditions, and in different healthcare systems, i.e., Israel, Korea, Switzerland, and several U.S. States. The components of the framework were validated against published scientific literature. Results: ACCESS stands for Advocating, Coping, Communication, cascadE Screening, and Surveillance. Each component is demonstrated in concrete examples of clinical practice within the scope of the nursing profession related to genomic healthcare. Key outcomes include advocacy, active coping, intrafamilial communication, cascade screening, and lifelong surveillance. Advocacy entails timely identification of at-risk individuals, facilitating referrals to specialized services, and informed decision-making for testing. Active coping enhances lifelong adaptation and management of disease risk. Effective intrafamilial communication of predisposition to hereditary disease supports cascade testing of unaffected at-risk relatives. Lifelong surveillance is essential for identifying recurrence, changes in health status, and disease trajectory for life-threatening and for life-altering conditions. Discussion: ACCESS provides a standardized, systematic, situational, and unifying guide to practice and is applicable for nursing and for other healthcare professions. When appropriately enacted it will contribute towards equitable access to genomic resources and services.

Abstract
In the 20 years since the initial sequencing of the human genome, genomics has become increasingly relevant to nursing. We sought to chart the current state of genomics in nursing by conducting a systematic scoping review of the literature in four databases (2012-2022). The included articles were categorized according to the Cochrane Collaboration outcome domains/sub-domains, and thematic analysis was employed to identify key topical areas to summarize the state of the science. Of 8532 retrieved articles, we identified 232 eligible articles. The articles primarily reported descriptive studies from the United States and other high-income countries (191/232, 82%). More than half (126/232, 54.3%) aligned with the "healthcare provider oriented outcomes" outcome domain. Three times as many articles related to the "knowledge and understanding" sub-domain compared to the "consultation process" subdomain (96 vs. 30). Five key areas of focus were identified, including "nursing practice" (50/126, 40%), "genetic counseling and screening" (29/126, 23%), "specialist nursing" (21/126, 17%), "nurse preparatory education" (17/126, 13%), and "pharmacogenomics" (9/126, 7%). Only 42/126 (33%) articles reported interventional studies. To further integrate genomics into nursing, study findings indicate there is a need to move beyond descriptive work on knowledge and understanding to focus on interventional studies and implementation of genomics into nursing practice.

Abstract
Co-creating patient-facing educational materials (PEMs) can enhance person-centered care by responding to patient priorities and unmet needs. Little data exist on 'best practices' for co-creation. We followed the Arksey and O'Malley framework to conduct a systematic literature search of nine databases (MEDLINE, PubMed, EMBASE, CINAHL, PsycINFO, Web of Science, Cochrane Library, Joanna Briggs Institute, TRIP-April, 2022) to identify empirical studies published in English on PEM co-creation to distill 'best practices'. Following an independent dual review of articles, data were collated into tables, and thematic analysis was employed to synthesize 'best practices' that were validated by a patient experienced in co-creating PEMs. Bias was not assessed, given the study heterogeneity. Of 6998 retrieved articles, 44 were included for data extraction/synthesis. Studies utilized heterogeneous methods spanning a range of health conditions/populations. Only 5/45 (11%) studies defined co-creation, 14 (32%) used a guiding framework, and 18 (41%) used validated evaluation tools. Six 'best practices' were identified: (1) begin with a review of the literature, (2) utilize a framework to inform the process, (3) involve clinical and patient experts from the beginning, (4) engage diverse perspectives, (5) ensure patients have the final decision, and (6) employ validated evaluation tools. This scoping review highlights the need for clear definitions and validated evaluation measures to guide and assess the co-creation process. Identified 'best practices' are relevant for use with diverse patient populations and health issues to enhance person-centered care.

Abstract
This study aimed to gain a deeper understanding of genomic healthcare utilization, patient activation, and intrafamilial risk communication among racially and ethnically diverse individuals tested for BRCA variants. We employed an explanatory, sequential, mixed-methods study guided by the Theory of Planned Behavior. Participants completed an online survey, including sociodemographic, medical history, and several validated instruments. A subset of participants participated in in-depth, semi-structured interviews. A total of 242 women were included in the quantitative analyses. The majority of survey participants identified as non-Hispanic white (NHW) (n = 197, 81.4%) while 45/242 (18.5%) identified as black, Indigenous, and people of color (BIPOC). The NHW participants were more likely to communicate genetic test results with healthcare providers, family, and friends than BIPOC participants (p < 0.05). BIPOC participants had lower satisfaction with testing decisions and significantly higher ratings of personal discrimination, fatalism, resilience, uncertainty, and lower patient activation scores (p < 0.05). Participants with higher education, greater satisfaction with testing decisions, and lower resilience are more likely to communicate BRCA test results with family members through the mediating effect of patient activation. Bridging disparities to ensure that genomic healthcare benefits all people may demand theory-driven, multi-level interventions targeting the individual, interpersonal, and healthcare system levels.

Abstract
Background Metabolic programming of glucose homeostasis in the first 1,000 days of life may impact lifelong metabolic and cardiovascular health. Continuous glucose monitoring (CGM) devices may help measure the impact of dietary intake on glucose rhythms and metabolism in infants during the complementary feeding period. Objectives Demonstrate the feasibility of CGM to measure and quantify glucose variability in response to infant feeding and to evaluate associations between macronutrient meal composition and glucose variability. Methods The "FreeStyle Libre Pro®" device interstitial glucose meter was applied to the anterior thigh of 10 healthy 6-12-month-old infants. Parents recorded food intake, time of feeding, and used daily dairies to record sleep time and duration. Descriptive statistics were employed for food intake, sleep and key glycemic parameters over three full days. Mixed linear models were used to assess glycemic changes. Results Mid-day, afternoon, and evening feeds contained >30 g carbohydrate and induced higher 2-h iAUC (3.42, 3.41, and 3.50 mmol/L*h respectively) compared to early and mid-morning feedings with ≤25 g carbohydrates (iAUC 2.72 and 2.81 mmol/L*h, p < 0.05). Early morning and evening milk feedings contained approximately 9 g of fat and induced a longer time to reach maximal glucose value (Tmax; 75 and 68 min, respectively) compared to lower fat feedings (2.9-5.9 g; Tmax range: 34-60 min; p < 0.05). Incremental glucose value at time of food intake (C0) increased significantly from 0.24 ± 0.39 mM in early morning to 1.07 ± 0.57 mM in the evening (p < 0.05). Over the day, 70% of glucose values remained within the normal range (3.5-5.5 mmol/L), 10% were between 5.5-10 mmol/L, and 20% were < 3.5 mmol/L. Conclusion Our data support the feasibility of using CGM to measure glucose in 6-12-month-old infants. The observation of possible diurnal glucose variability and typical glucose values may have implications for future studies investigating metabolic adaptation to nutritional intake in early life.

Abstract
CONTEXT Isolated hypogonadotropic hypogonadism (IHH) is phenotypically and genetically heterogeneous. OBJECTIVE This work aimed to determine the correlation between genotypic severity with pubertal and neuroendocrine phenotypes in IHH men. METHODS A retrospective study was conducted (1980-2020) examining olfaction (Kallmann syndrome [KS] vs normosmic IHH [nHH]), baseline testicular volume (absent vs partial puberty), neuroendocrine profiling (pulsatile vs apulsatile luteinizing hormone [LH] secretion), and genetic variants in 62 IHH-associated genes through exome sequencing (ES). RESULTS In total, 242 men (KS: n = 131 [54%], nHH: n = 111 [46%]) were included. Men with absent puberty had significantly lower gonadotropin levels (P < .001) and were more likely to have undetectable LH (P < .001). Logistic regression showed partial puberty as a statistically significant predictor of pulsatile LH secretion (R2 = 0.71, P < .001, OR: 10.8; 95% CI, 3.6-38.6). Serum LH of 2.10 IU/L had a 95% true positive rate for predicting LH pulsatility. Genetic analyses in 204 of 242 IHH men with ES data available revealed 36 of 204 (18%) men carried protein-truncating variants (PTVs) in 12 IHH genes. Men with absent puberty and apulsatile LH were enriched for oligogenic PTVs (P < .001), with variants in ANOS1 being the predominant PTV in this genotype-phenotype association. Men with absent puberty were enriched for ANOS1 PTVs compared to partial puberty counterparts (P = .002). PTVs in other IHH genes imparted more variable reproductive phenotypic severity. CONCLUSION Partial puberty and LH greater than or equal to 2.10 IU/L are proxies for pulsatile LH secretion. ANOS1 PTVs confer severe reproductive phenotypes. Variable phenotypic severity in the face of severe genetic variants in other IHH genes point to significant neuroendocrine plasticity of the HPG axis in IHH men.

Abstract
BACKGROUND The Chronic Care Model (CCM) is a longstanding and widely adopted model guiding chronic illness management. Little is known about how CCM elements are implemented in rare disease care or how patients' care experiences relate to health-related quality of life (HRQoL). We engaged patients living with systemic sclerosis (SSc) to assess current care according to the CCM from the patient perspective and their HRQoL. METHODS We employed an explanatory sequential mixed methods design. First, we conducted a cross-sectional quantitative survey (n = 101) using the Patient Assessment of Chronic Illness Care (PACIC) and Systemic Sclerosis Quality of Life (SScQoL) questionnaires. Next, we used data from individual patient interviews (n = 4) and one patient focus group (n = 4) to further explore care experiences of people living with SSc with a focus on the PACIC dimensions. RESULTS The mean overall PACIC score was 3.0/5.0 (95% CI 2.8-3.2, n = 100), indicating care was 'never' to 'generally not' aligned with the CCM. Lowest PACIC subscale scores related to 'goal setting/tailoring' (mean = 2.5, 95% CI 2.2-2.7) and 'problem solving/contextual counselling' (mean = 2.9, 95% CI 2.7-3.2). No significant correlations were identified between the mean PACIC and SScQoL scores. Interviews revealed patients frequently encounter major shortcomings in care including 'experiencing organized care with limited participation', 'not knowing which strategies are effective or harmful' and 'feeling left alone with disease and psychosocial consequences'. Patients often responded to challenges by 'dealing with the illness in tailored measure', 'taking over complex coordination of care' and 'relying on an accessible and trustworthy team'. CONCLUSIONS The low PACIC mean overall score is comparable to findings in patients with common chronic diseases. Key elements of the CCM have yet to be systematically implemented in Swiss SSc management. Identified gaps in care related to lack of shared decision-making, goal-setting and individual counselling-aspects that are essential for supporting patient self-management skills. Furthermore, there appears to be a lack of complex care coordination tailored to individual patient needs.

Abstract
STUDY QUESTION What is known about health-related quality of life (HR-QoL) in women with idiopathic primary ovarian insufficiency (POI)? SUMMARY ANSWER Women with POI have a range of unmet psychosocial needs relating to three interrelated themes: 'diagnostic odyssey', 'isolation and stigma' and impaired 'ego integrity'. WHAT IS KNOWN ALREADY Prior studies have reported increased depressive symptoms, diminished sexual function and altered body image/self-concept in women with POI. STUDY DESIGN, SIZE, DURATION A systematic scoping review (11 databases) on HR-QoL in POI including published quantitative, qualitative and mixed-methods studies as well as unpublished gray literature (i.e. unpublished dissertations) through June, 2021. PARTICIPANTS/MATERIALS, SETTING, METHODS After removing duplicates, 1244 articles underwent title and abstract review by independent reviewers. The remaining 72 relevant articles underwent dual full text review to determine inclusion criteria yielding 24 articles (100% concordance) for data extraction. Findings were summarized in tables by methodology and recurrent HR-QoL themes/sub-themes were mapped to define key aspects of HR-QoL in POI. Promoters of active coping were charted at the individual, interpersonal and healthcare system levels. Targets for tailored interventions supporting active coping and improved HR-QoL were mapped to the Theory of Planned Behavior (TPB). MAIN RESULTS AND THE ROLE OF CHANCE Three interrelated themes affecting HR-QoL in POI emerged from the data synthesis. First, the theme 'diagnostic odyssey' comprised sub-themes of uncertainty, lack of control, knowledge gaps, discontinuous care and negative clinical interactions. The second theme 'isolation and stigma' included sub-themes of guilt, shame, concealment, feeling labeled as infertile, lack of social support and unsympathetic clinicians. The third theme, impaired 'ego integrity' captured sub-themes of decreased sexual function, altered body image, psychological vulnerability and catastrophizing. Targets promoting active coping at the individual (n = 2), interpersonal (n = 1) and healthcare system (n = 1) levels were mapped to the TPB to inform development of tailored interventions supporting active coping and improved HR-QoL in POI (i.e. narrative intervention, co-creating patient-facing materials, peer-to-peer support and provider resources). LIMITATIONS, REASONS FOR CAUTION No studies using a POI-specific HR-QoL instrument were identified. No interventional studies aimed at improving HR-QoL in POI were identified. Only articles published in English were included in the study. WIDER IMPLICATIONS OF THE FINDINGS Women with POI frequently have impaired HR-QoL related to the life-altering infertility diagnosis. The range of unmet psychosocial needs may be relevant for informing interventions for other populations with infertility.

Abstract
Congenital hypogonadotropic hypogonadism (HH) is a heterogeneous genetic disorder characterized by disrupted puberty and infertility. In most cases, HH is abiding yet 10-15% undergo reversal. Men with HH and absent and partial puberty (i.e., testicular volume <4mL and >4mL respectively) have been well-studied, but the rare fertile eunuch (FE) variant remains poorly characterized. This natural history study of 240 men with HH delineates the clinical presentation, neuroendocrine profile, rate of reversal and genetics of the FE variant. We compared three HH groups: FE (n=38), absent puberty (n=139), and partial puberty (n=63). The FE group had no history of micropenis and 2/38 (5%) had cryptorchidism (p<0.0001 vs. other groups). The FE group exhibited higher rates of detectable gonadotropins, higher mean LH/FSH levels, and higher serum inhibin B levels (all p<0.0001). Neuroendocrine profiling showed pulsatile LH secretion in 30/38 (79%) of FE men (p<0.0001) and 16/36 (44%) FE men underwent spontaneous reversal of HH (p<0.001). The FE group was enriched for protein-truncating variants (PTVs) in GNRHR and FGFR1 and 4/30 (13%) exhibited oligogenic PTVs. Findings suggest men with the FE variant exhibit the mildest neuroendocrine defects of HH men and the FE sub-type represents the first identified phenotypic predictor for reversible HH.

Abstract
Abstract
Background
Rare disease research is hampered in part by the fact that patients are geographically dispersed. Rare disease patient communities are recognized for their use of the internet to learn about their condition and find peer-to-peer support. As such, web-based technologies offer promise for overcoming geographic barriers in rare disease research for many. Qualitative focus groups (FGs) are a widely used methodology used to understand patients and parents/families ‘lived experience’ and unmet needs is important to improve care for rare diseases. It is unclear if web-enabled (virtual) FGs are comparable to traditional in-person approaches. We conducted in-person (n = 3) and virtual (n = 3) FGs with rare disease patients to determine if virtual FGs produce similar results in-person FGs.
Results
Three in-person (n = 33 participants) and three virtual (n = 25 participants) FGs were conducted examining attitudes and beliefs regarding genetic testing and family communication of risk. Participants included 30 males, 18 females, and 10 parents/guardians. Two independent investigators identified excerpts (meaningful sections of text) and coded themes/sub-themes using a codebook. Inter-coder agreement across identified excerpts (n = 530) in both FG formats was 844/875 (96.5%). Two additional investigators reviewed coded excerpts and did not identify additional themes/sub-themes—supporting data saturation across FG formats. Virtual FGs accounted for 303/530 (57.2%) of total excerpts and 957/1721 (55.7%) of all identified themes/sub-themes. Formats were similar in terms of overall number of excerpts (101 ± 7.8 vs. 75.7 ± 18.8, p = 0.26) and themes/sub-themes (319 ± 6.1 vs. 254.7 ± 103.6, p = 0.34) between virtual and in-person FGs. However, virtual FGs had significantly more coded excerpts specifically relating to sensitive/intimate topics including ‘attitudes and beliefs’ (n = 320 vs. n = 235, p < 0.001), ‘information and support’ (n = 184 vs. n = 99, p < 0.001), and ‘family communication’ (n = 208 vs. n = 114, p < 0.001).
Conclusions
Virtual FGs yielded similar numbers of coded excerpts compared to traditional in-person FGs. Virtual FGs appear to support the relative anonymity of participants, resulting in richer discussion of highly sensitive, intimate topics. Findings support the validity and methodologic rigor of using web-enabled technologies for conducting FGs in rare diseases.

Abstract
Background The American College of Obstetricians and Gynecologists recommends prenatal genetic testing (PGT) be offered to all pregnant persons regardless of known risk factors. However, significant racial/ethnic differences exist regarding acceptance of PGT contributing to disparities. Latinas (Latinx), one of the fastest growing ethnic groups in the United States, have low PGT acceptance rates. This systematic scoping review aimed to provide a landscape of existing literature on Latinx individuals’ knowledge of, preferences for, and experiences with prenatal and preconception genetic testing. Synthesizing the current state of the science may inform development of culturally tailored interventions to support high-quality PGT decisions (e.g., informed, aligned with a pregnant persons’ values). Methods We conducted a structured, systematic literature search of published articles and gray literature in electronic databases (PubMed, PsycINFO, CINAHL, Medline, Embase, Eric, Social Services Abstracts, and PsycArticles). Articles in English published prior to March 2021 were retrieved relating to genetics, pregnancy, and Latina women. Articles underwent title, abstract and full-text review by independent investigators to assess inclusion and exclusion criteria. Risk of bias was evaluated by two investigators. Iterative thematic analysis was employed to group study findings into themes to identify possible targets for interventions. Results The search generated 5511 unique articles. After title screening, 335 underwent abstract review and subsequently 61 full-text review. Twenty-eight studies met inclusion criteria and 7 additional studies were included after reviewing reference lists. Three overarching themes emerged: genetic knowledge/literacy (26/35, 74%), provider (mis)communication/patient satisfaction (21/35, 60%), and cross-cultural beliefs (12/35, 34%). Studies indicate discordant patient-provider language (n = 5), miscommunication (n = 4), and lack of concordant decision-making (n = 4) pose barriers to high-quality PGT decisions. Immigration status (n = 1) and religious beliefs (n = 5) are additional factors influencing PGT decisions. Conclusions Identified studies suggest that cultural and linguistic factors affect Latinx PGT decision-making. Latinx individual’s comprehension and recall of PGT information is enhanced by culturally and linguistically concordant providers—suggesting that culturally-informed interventions may enhance PGT acceptability and support high-quality decisions. Future directions to surmount PGT disparities may include community health workers and cultural brokers to empower Latinx people to make informed decisions aligned with their values and preferences. Supplementary Information The online version contains supplementary material available at 10.1186/s12978-022-01438-2. Significant racial, ethnic, and language disparities exist in prenatal genetic testing (PGT). Latina (Latinx) people, one of the fastest growing ethnic groups in the United States, have low acceptance rates of PGT. This scoping review provides a systematic search of the literature to better understand Latinx individuals’ knowledge of, preferences for, and experiences with PGT. Eight electronic data bases were systematically searched and identified articles underwent title, abstract, full text, and reference review. Iterative thematic analysis was conducted to group article findings into themes. Thirty-five studies met inclusion criteria and three overarching themes were identified: genetic knowledge/literacy, provider (mis)communication/patient satisfaction, and cross-cultural beliefs. Findings indicate that discordant patient-provider decision making and language and patient provider miscommunication pose barriers to high-quality PGT decisions. Latinx individuals’ understanding and recall of PGT information is improved when delivered in a culturally and linguistically concordant manner. This suggests culturally-informed interventions, including the use of community health workers or cultural brokers, may enhance PGT acceptability and support high quality pregnancy decisions.

Abstract
Most rare diseases are genetic in etiology and characterized by a ‘diagnostic odyssey’. Genomic advances have helped speed up the diagnosis for many rare disorders, opening new avenues for precision therapies. Little is known about patient attitudes, experiences, and beliefs about genetic testing for the rare disease congenital hypogonadotropic hypogonadism (CHH). Methods: We conducted six focus groups with patients with CHH (n = 58). Transcripts were coded by independent investigators and validated by external reviewers. Results: Major themes relating to pre-test experiences were ‘attitudes & beliefs’ (most frequently cited theme), which revealed altruism as a strong motivator for pursuing research testing and ‘information and support,’ which revealed a striking lack of pre-testing decisional support/genetic counseling. Major post-test themes included ‘return of results,’ revealing frustration with the lack of return of results and limited emotional support, and ‘family communication,’ describing challenging intrafamilial communication. Themes describing ethical concerns (i.e., privacy, use of samples) were least frequently noted and related to pre- and post-test experiences. Conclusions: Patients with CHH are highly motivated by altruism when pursuing testing but have significant unmet needs for pre-test decisional support and post-test counseling. It is regarded that patient values, beliefs and experiences can inform more person-centered approaches to genetic testing for rare diseases.

Abstract
OBJECTIVE The insulin tolerance test (ITT) is the gold standard endocrine test used to assess the integrity of the growth hormone (GH) and cortisol axes. The ITT has potential risks, and severe hypoglycaemia may necessitate intravenous glucose rescue. There is no clear consensus as to the optimal insulin dose for the ITT. Therefore, we sought to compare the standard dose (0.15 U/kg) and a low-dose ITT (0.1 U/kg). DESIGN Single-centre audit of ITT data (2012-2021). Patients and Measurements. Patients who underwent an ITT to assess possible GH deficiency/adrenal insufficiency were included. Glucose, GH, and cortisol were measured at baseline and 30, 45, 60, 90, and 120 minutes following I.V. insulin bolus (0.15 U/kg or 0.10 U/kg). RESULTS Of the ITTs performed, only 3/177 (1.7%) did not achieve adequate hypoglycaemia (≤2.2 mmol/L) with a single insulin dose. In total, 174 patients (43.5 ± 12.1 yrs, mean ± standard deviation) were included for analysis (0.15 U/kg: n = 113, 0.10 U/kg: n = 61). All 174 subjects had adequate hypoglycaemia regardless of baseline fasting blood glucose level or insulin dose. Neither nadir glucose nor glucose delta (i.e., baseline minus nadir) differed between insulin doses. Trends in both cortisol and GH responses over time were similar between groups, and a greater proportion of patients receiving the standard dose had an adequate cortisol response (77/106 (72.6%) vs. 32/60 (53.3%), p=0.01). The rates of glucose rescue did not differ in a subset of 79 patients, with on-demand glucose rescue in 4/35 (11%) for the standard dose and 2/44 (5%) for the low dose (p=0.25). CONCLUSIONS Our results suggest that the low-dose ITT produces comparable glucose, cortisol, and GH responses to the higher dose. Given the risks associated with hypoglycaemia, the low dose appears to be preferable to the standard dose ITT in most circumstances.

Abstract
Klinefelter syndrome (KS) is the most common aneuploidy in men and has long-term sequelae on health and wellbeing. KS is a chronic, lifelong condition and adolescents/young adults (AYAs) with KS face challenges in transitioning from pediatric to adult-oriented services. Discontinuity of care contributes to poor outcomes for health and wellbeing and transition programs for KS are lacking. We aimed to develop and test a mobile health tool (KS Transition Passport) to educate patients about KS, encourage self-management and support successful transition to adult-oriented care. First, we conducted a retrospective chart review and patient survey to examine KS transition at a university hospital. Second, we conducted a systematic scoping review of the literature on AYAs with KS. Last, we developed a mobile health transition passport and evaluated it with patient support groups. Participants evaluated the tool using the System Usability Scale and Patient Education Materials Assessment Tool (PEMAT). Chart review identified 21 AYAs diagnosed between 3.9-16.8 years-old (median 10.2 years). The survey revealed only 4/10 (40%) were on testosterone therapy and fewer (3/10, 30%) had regular medical care. The scoping review identified 21 relevant articles highlighting key aspects of care for AYAs with KS. An interprofessional team developed the mobile-health KS transition passport using an iterative process. Support group members (n=35) rated passport usability as 'ok' to 'good' (70 ± 20, median 73.5/100). Of PEMAT dimensions, 5/6 were deemed 'high quality' (86-90/100) and participants knew what to do with the information (actionability = 83/100). In conclusion, many patients with KS appear to have gaps in transition to adult-oriented care. Iterative development of a KS transition passport produced a mobile health tool that was usable, understandable and had high ratings for actionability.

Abstract
BACKGROUND Decision coaching is non-directive support delivered by a healthcare provider to help patients prepare to actively participate in making a health decision. 'Healthcare providers' are considered to be all people who are engaged in actions whose primary intent is to protect and improve health (e.g. nurses, doctors, pharmacists, social workers, health support workers such as peer health workers). Little is known about the effectiveness of decision coaching. OBJECTIVES To determine the effects of decision coaching (I) for people facing healthcare decisions for themselves or a family member (P) compared to (C) usual care or evidence-based intervention only, on outcomes (O) related to preparation for decision making, decisional needs and potential adverse effects. SEARCH METHODS We searched the Cochrane Library (Wiley), Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), Embase (Ovid), PsycINFO (Ovid), CINAHL (Ebsco), Nursing and Allied Health Source (ProQuest), and Web of Science from database inception to June 2021. SELECTION CRITERIA We included randomised controlled trials (RCTs) where the intervention was provided to adults or children preparing to make a treatment or screening healthcare decision for themselves or a family member. Decision coaching was defined as: a) delivered individually by a healthcare provider who is trained or using a protocol; and b) providing non-directive support and preparing an adult or child to participate in a healthcare decision. Comparisons included usual care or an alternate intervention. There were no language restrictions. DATA COLLECTION AND ANALYSIS Two authors independently screened citations, assessed risk of bias, and extracted data on characteristics of the intervention(s) and outcomes. Any disagreements were resolved by discussion to reach consensus. We used the standardised mean difference (SMD) with 95% confidence intervals (CI) as the measures of treatment effect and, where possible, synthesised results using a random-effects model. If more than one study measured the same outcome using different tools, we used a random-effects model to calculate the standardised mean difference (SMD) and 95% CI. We presented outcomes in summary of findings tables and applied GRADE methods to rate the certainty of the evidence. MAIN RESULTS Out of 12,984 citations screened, we included 28 studies of decision coaching interventions alone or in combination with evidence-based information, involving 5509 adult participants (aged 18 to 85 years; 64% female, 52% white, 33% African-American/Black; 68% post-secondary education). The studies evaluated decision coaching used for a range of healthcare decisions (e.g. treatment decisions for cancer, menopause, mental illness, advancing kidney disease; screening decisions for cancer, genetic testing). Four of the 28 studies included three comparator arms. For decision coaching compared with usual care (n = 4 studies), we are uncertain if decision coaching compared with usual care improves any outcomes (i.e. preparation for decision making, decision self-confidence, knowledge, decision regret, anxiety) as the certainty of the evidence was very low. For decision coaching compared with evidence-based information only (n = 4 studies), there is low certainty-evidence that participants exposed to decision coaching may have little or no change in knowledge (SMD -0.23, 95% CI: -0.50 to 0.04; 3 studies, 406 participants). There is low certainty-evidence that participants exposed to decision coaching may have little or no change in anxiety, compared with evidence-based information. We are uncertain if decision coaching compared with evidence-based information improves other outcomes (i.e. decision self-confidence, feeling uninformed) as the certainty of the evidence was very low. For decision coaching plus evidence-based information compared with usual care (n = 17 studies), there is low certainty-evidence that participants may have improved knowledge (SMD 9.3, 95% CI: 6.6 to 12.1; 5 studies, 1073 participants). We are uncertain if decision coaching plus evidence-based information compared with usual care improves other outcomes (i.e. preparation for decision making, decision self-confidence, feeling uninformed, unclear values, feeling unsupported, decision regret, anxiety) as the certainty of the evidence was very low. For decision coaching plus evidence-based information compared with evidence-based information only (n = 7 studies), we are uncertain if decision coaching plus evidence-based information compared with evidence-based information only improves any outcomes (i.e. feeling uninformed, unclear values, feeling unsupported, knowledge, anxiety) as the certainty of the evidence was very low. AUTHORS' CONCLUSIONS Decision coaching may improve participants' knowledge when used with evidence-based information. Our findings do not indicate any significant adverse effects (e.g. decision regret, anxiety) with the use of decision coaching. It is not possible to establish strong conclusions for other outcomes. It is unclear if decision coaching always needs to be paired with evidence-informed information. Further research is needed to establish the effectiveness of decision coaching for a broader range of outcomes.

Abstract
OBJECTIVE Providing genetic counseling and genetic testing to at-risk blood relatives (cascade screening) is important for improving BRCA cancer outcomes. Intra-familial communication of risk is critical for cascade screening efforts yet relatively little is known about men's role in communicating BRCA risk. We sought to examine men's coping response to their BRCA status and intra-familial communication of risk to inform the development of tailored interventions that could promote cascade screening. METHODS We employed a sequential mixed-methods design. First, we measured coping response (quantitative) using the Multidimensional Impact of Cancer Risk Assessment (MICRA). MICRA scores were compared between BRCA+ men, BRCA- men and BRCA+ women. Subsequently, we used template analysis to analyze qualitative interviews exploring coping and intra-familial communication of risk. The Theory of Planned Behavior (TPB) served as a guiding framework for identifying intervention targets. RESULTS BRCA+ men (n = 36) had significantly higher levels of distress (p < 0.001), uncertainty (p < 0.001) and negative experiences (p < 0.05) compared to BRCA- male counterparts (n = 23). BRCA+ men had significantly lower distress (p < 0.001) and uncertainty (p < 0.001) than BRCA+ women (n = 406). Qualitative analysis of in-depth interviews with BRCA+ men (n = 35) identified promoters and barriers to active coping response and intra-familial communication of risk. Mapping results onto the TPB identified targets for tailoring person-centered approaches for men addressing beliefs/attitude, subjective norms, and perceived behavioral control. CONCLUSIONS Men and women appear to have different coping responses to learning their BRCA status. Developing tailored (sex-based), theory informed interventions may help promote intra-familial communication of BRCA risk and support cascade screening.

Abstract
OBJECTIVES We engaged patients with systemic sclerosis (SSc) and healthcare professionals to assess electronic health (eHealth) literacy and needs relating to web-based support using internet-based information and communication technologies (ICT). METHODS We employed an explanatory sequential mixed methods design. First, we conducted a cross-sectional survey in patients (n=101) and professionals (n=47). Next, we conducted three focus groups with patients, family members and professionals (n=17). RESULTS Of patients, 89.1% used ICT at least weekly for private communication. Patients reported relatively high comprehension of eHealth information ([Formula: see text] =6.7, 95% CI: 6.2 to 7.3, range 1-10), yet were less confident evaluating information reliability ([Formula: see text] =5.8, 95% CI: 5.1 to 6.4) and finding eHealth apps ([Formula: see text] =4.8, 95% CI: 4.2 to 5.4). Patients and professionals reported little experience with web-based self-management support. Focus groups revealed 'considering non-ICT-accessible groups' and 'fitting patients' and professionals' technology' as crucial for acceptability. In relation to understanding/appraising eHealth, participants highlighted that general SSc information is not tailored to individual's disease course. Recommendations included 'providing timely, understandable and safe information' and 'empowering end-users in ICT and health decision-making skills'. Professionals expressed concerns about lacking resources. Patients were concerned about data security and person-centredness. Key eHealth drivers included 'addressing end-user perceptions' and 'putting people at the centre of technology'. CONCLUSIONS Patients and professionals need education/training to support uptake of eHealth resources. Key elements include guiding patients to timely/reliable information and using eHealth to optimise patient-provider communication. Design that is responsive to end-users' needs and considers individuals with limited eHealth literacy and/or ICT access appears to be critical for acceptability.

Abstract
Background Rare disease patient-reported outcome measures (PROMs) require linguistic adaptation to overcome the challenge of geographically dispersed patient populations. Importantly, PROMs such as health-related quality of life (HRQoL) should accurately capture responses to patient-identified concerns. The Systemic Sclerosis Quality of Life Questionnaire (SScQoL) is a 29-item tool validated in six languages. Previous evaluation of the German version revealed problems with dichotomous responses. This study aimed to revise the German SScQoL, extend the response structure, and evaluate content and construct validity, reliability and unidimensionality. Methods The instrument validation study involved revising the German SScQoL response structure, cognitive debriefing with patients and validation using Rasch analysis. The revised SScQoL was completed by Swiss-German-speaking patients with SSc within the Swiss MANagement Of Systemic Sclerosis (MANOSS) study. Rasch analysis was employed to test the validity, reliability and unidimensionality of the revised instrument. Results Based on cognitive debriefing with patients (n = 6) dichotomous items were extended to a polytomous 4-point response structure. A total of 78 patients completed the revised SScQoL. Initial analysis of the 29 items suggested the scale lacked fit to the model (χ2 = 51.224, df = 29, p = 0.007). Grouping items into five domains resulted in an adequate fit to the Rasch model (χ2 = 5.343, df = 5, p = 0.376) and unidimensionality (proportion of significant independent t tests: 0.045, 95% CI 0.016–0.114). Overall, the scale was well targeted, had high internal consistency (Person Separation Index, PSI = 0.931) and worked consistently in patients with different demographic and clinical characteristics. Conclusions The revised German SScQoL has a 4-point response structure and is a valid, reliable measure. Rasch analysis is useful for validating continuous response structure of quality of life measures. Further evaluation of measurement equivalence with other German-speaking cultures is required for multinational comparisons and data pooling.

Abstract
The Endocrine Nurses Society (ENS) is committed to clinical excellence in the art and science of endocrine nursing throughout the world. ENS recognizes that transgender and gender diverse (TGD) individuals face challenges and inequities that place them in the realm of health disparities. Further, TGD individuals often face substantial barriers to care and have difficulty finding healthcare providers who are knowledgeable about the unique health needs of this patient population. ENS recognizes that endocrine nurses care for young adult and adult TGD individuals. This position statement outlines recommendations for healthcare providers and organizations seeking to embrace a gender-affirming approach to care and increase access to high-quality, comprehensive care for TGD individuals. This Position Statement was accepted by ENS on September 8, 2020 and has been endorsed by the European Society of Endocrinology Nurse Committee, European Society of Paediatric Endocrinology Nurses, Pediatric Endocrine Nursing Society, Endocrine Nurses' Society of Australasia, and the Federation of International Nurses in Endocrinology.

Abstract
BACKGROUND Central precocious puberty (CPP) in females is characterized by thelarche before 8 years of age. Evidence of reproductive axis activation confirms the diagnosis (basal serum luteinizing hormone (LH) ≥0.3 IU/L or LH-releasing hormone (LHRH)-stimulated LH ≥5 IU/L). Stimulation testing is the diagnostic gold standard but is time-consuming and costly. Serum levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein 3 (IGFBP-3) are increased in girls with CPP. OBJECTIVE The aim of the study was to assess the utility of serum IGF-1 and IGFBP-3 in identifying CPP in girls aged 6-8 years. METHODS The study was a single-center retrospective study. Girls with confirmed CPP (n = 44) and isolated premature precocious adrenarche/ precocious thelarche (PA/PT, n = 16) had baseline biochemical profiling and LHRH stimulation testing. Serum IGF-1 and IGFBP-3 results were converted to standard deviation scores (SDS). Correlations were calculated and receiver operating characteristic curves were plotted. RESULTS Girls with CPP had higher basal and peak LH, IGF-1 SDS, and growth velocity (p < 0.05). IGF-1 SDS correlated positively with basal and peak LH (p < 0.05). IGF-1 SDS (1.75-2.15) differentiated CPP and PA/PT with 89% sensitivity and 56% specificity (basal LH) and 94% specificity and 55% sensitivity (peak LH). IGFBP-3 SDS did not differ between groups or by CPP parameters. CONCLUSIONS In clinical practice, IGF-1 SDS may be an additional tool for identifying CPP in girls aged 6 to 8 years when baseline clinical and laboratory diagnostic criteria are inconclusive, possibly avoiding more time-consuming and costly procedures.

Abstract
Genetic testing is increasingly part of routine clinical care. However, testing decisions may be characterized by regret as findings also implicate blood relatives. It is not known if genetic testing decisions are affected by the way information is presented (i.e., framing effects). We employed a randomized factorial design to examine framing effects on hypothetical genetic testing scenarios (common, life-threatening disease and rare, life-altering disease). Participants (n = 1012) received one of six decision frames: choice, default (n = 2; opt-in, opt-out), or enhanced choice (n = 3, based on the Theory of Planned Behavior). We compared testing decision, satisfaction, regret, and decision cognitions across decision frames and between scenarios. Participants randomized to ‘choice’ were least likely to opt for genetic testing compared with default and enhanced choice frames (78% vs. 83–91%, p < 0.05). Neither satisfaction nor regret differed across frames. Perceived autonomy (behavioral control) predicted satisfaction (B = 0.085, p < 0.001) while lack of control predicted regret (B = 0.346, p < 0.001). Opting for genetic testing did not differ between disease scenarios (p = 0.23). Results suggest framing can nudge individuals towards opting for genetic testing. These findings have important implications for individual self-determination in the genomic era. Similarities between scenarios with disparate disease trajectories point to possible modular approaches for web-based decisional support.

Abstract
Background Rare disease patients are geographically dispersed, posing challenges to research. Some researchers have partnered with patient organizations and used web-based approaches to overcome geographic recruitment barriers. Critics of such methods claim that samples are homogenous and do not represent the broader patient population—as patients recruited from patient organizations are thought to have high levels of needs. We applied latent class mixture modeling (LCMM) to define patient clusters based on underlying characteristics. We used previously collected data from a cohort of patients with congenital hypogonadotropic hypogonadism who were recruited online in collaboration with a patient organization. Patient demographics, clinical information, Revised Illness Perception Questionnaire (IPQ-R) scores and Zung self-rating depression Scale (SDS) were used as variables for LCMM analysis. Specifically, we aimed to test the classic critique that patients recruited online in collaboration with a patient organization are a homogenous group with high needs. We hypothesized that distinct classes (clinical profiles) of patients could be identified—thereby demonstrating the validity of online recruitment and supporting transferability of findings. Results In total, 154 patients with CHH were included. The LCMM analysis identified three distinct subgroups (Class I: n = 84 [54.5%], Class II: n = 41 [26.6%], Class III: n = 29 [18.8%]) that differed significantly in terms of age, education, disease consequences, emotional consequences, illness coherence and depression symptoms (all p < 0.001) as well as age at diagnosis (p = 0.045). Classes depict a continuum of psychosocial impact ranging from severe to relatively modest. Additional analyses revealed later diagnosis (Class I: 19.2 ± 6.7 years [95% CI 17.8–20.7]) is significantly associated with worse psychological adaptation and coping as assessed by disease consequences, emotional responses, making sense of one’s illness and SDS depressive symptoms (all p < 0.001). Conclusions We identify three distinct classes of patients who were recruited online in collaboration with a patient organization. Findings refute prior critiques of patient partnership and web-based recruitment for rare disease research. This is the first empirical data suggesting negative psychosocial sequelae of later diagnosis (“diagnostic odyssey”) often observed in CHH.

Abstract
BACKGROUND Two loci (CHD7 and SOX10) underlying Kallmann syndrome (KS) were discovered through clinical and genetic analysis of CHARGE and Waardenburg syndromes, conditions that include congenital anosmia caused by olfactory bulb (CA/OBs) defects and congenital hypogonadotropic hypogonadism (CHH). We hypothesized that other candidate genes for KS could be discovered by analyzing rare syndromes presenting with these signs. Study Design, Size, Duration: We first investigated a family with Gorlin-Goltz syndrome (GGS) in which affected members exhibited clinical signs suggesting KS. Participants/Materials, Methods: Proband and family members underwent detailed clinical assessment. The proband received detailed neuroendocrine evaluation. Genetic analyses included sequencing the PTCH1 gene at diagnosis, followed by exome analyses of causative or candidate KS/CHH genes, in order to exclude contribution to the phenotypes of additional mutations. Exome analyses in additional 124 patients with KS/CHH probands with no additional GGS signs. RESULTS The proband exhibited CA, absent OBs on magnetic resonance imaging, and had CHH with unilateral cryptorchidism, consistent with KS. Pulsatile Gonadotropin-releasing hormone (GnRH) therapy normalized serum gonadotropins and increased testosterone levels, supporting GnRH deficiency. Genetic studies revealed 3 affected family members harbor a novel mutation of PTCH1 (c.838G> T; p.Glu280*). This unreported nonsense deleterious mutation results in either a putative truncated Ptch1 protein or in an absence of translated Ptch1 protein related to nonsense mediated messenger RNA decay. This heterozygous mutation cosegregates in the pedigree with GGS and CA with OBs aplasia/hypoplasia and with CHH in the proband suggesting a genetic linkage and an autosomal dominant mode of inheritance. No pathogenic rare variants in other KS/CHH genes cosegregated with these phenotypes. In additional 124 KS/CHH patients, 3 additional heterozygous, rare missense variants were found and predicted in silico to be damaging: p.Ser1203Arg, p.Arg1192Ser, and p.Ile108Met. CONCLUSION This family suggests that the 2 main signs of KS can be included in GGS associated with PTCH1 mutations. Our data combined with mice models suggest that PTCH1 could be a novel candidate gene for KS/CHH and reinforce the role of the Hedgehog signaling pathway in pathophysiology of KS and GnRH neuron migration.

Abstract
Patients often have difficulty understanding genetic test reports. Technical language and jargon can impede comprehension and limit patients using results to act on findings. One potential way to improve patient understanding of genetic test reports is to provide patient-facing materials. This study aimed to examine understandability and actionability of co-created patient-facing materials for genetic test results in a research context. We combined interprofessional perspectives and patient engagement to co-create patient-facing materials for patients undergoing research genetic testing for congenital hypogonadotropic hypogonadism (Kallmann syndrome). The iterative development process was guided by principles of health literacy and human-centered design (i.e., design thinking). Readability was assessed using eight validated algorithms. Patients and parents evaluated materials using a web-based survey. The gold standard Patient Education Materials Assessment Tool for print materials (PEMAT-P) was employed to measure understandability (content, style, use of numbers, organization, design, use of visual aids) and actionability. PEMAT-P scores >80% were considered high quality. Results were analyzed descriptively and correlations performed to identify relationships between education/health literacy and PEMAT-P ratings. A consensus score of eight algorithms indicated the materials were an 8th -9th grade reading level. Our findings are consistent with the U.S. Department of Health and Human Services 'average difficulty' classification (i.e., 7th-9th grade). In total, 61 patients/parents evaluated the materials. 'Visual Aids' received the lowest mean PEMAT-P rating (89%). All other parameters scored 90%-97%. PEMAT-P scores did not differ according to educational attainment (less than college vs. college or more, p = 0.28). Participants with adequate health literacy were more likely to approve of the 'organization' of information (p < 0.05). Respondents with low health literacy had more favorable views of 'visual aids' (p < 0.01). Involving patients in a co-creation process can produce high-quality patient-facing materials that are easier to understand.

Abstract
BACKGROUND Sexual healthcare is a critical component of well-being. Sexual health disparities persist nationally. Nurses and advanced practice nurses are well positioned to provide sexual healthcare to diverse patient populations. However, many nurses do not feel prepared to provide comprehensive care and sexual health curricula vary widely across schools of nursing. OBJECTIVES We aimed to evaluate the effectiveness of a new sexual health course for graduate students in improving nurses' knowledge, preparedness, comfort, and confidence in delivering comprehensive, culturally informed sexual healthcare. DESIGN A pre-post-intervention survey study design was utilized to assess course effectiveness. SETTING Medium-sized, private university. PARTICIPANTS Graduate nursing students enrolled in the course (intervention group, n = 30) were recruited. Graduate students enrolled at the institution but not enrolled in the course served as controls (n = 64). METHODS Descriptive statistics and multivariate analysis were used to evaluate pre- to post-course changes in knowledge, preparedness, comfort, and confidence in the intervention group and differences between the intervention and control group at baseline. RESULTS At baseline, all participants (n = 94) exhibited high objective clinical sexual health knowledge. The intervention group had significantly increased overall preparedness, comfort, and confidence in providing sexual healthcare to diverse patient populations. In particular, participants in the intervention group had statistically significant increases associated with care for marginalized minority populations (sexual minorities, gender minorities, sex workers, and persons with a history of sexual trauma). CONCLUSIONS The graduate-level course on sexual health and sexual health disparities effectively increased perceived preparedness, comfort, and confidence in delivering comprehensive and culturally informed care to diverse populations. Nursing programs should evaluate their curricula to determine whether graduates are optimally prepared.

Abstract
Abstract
STUDY QUESTION
Are GnRH tests and serum inhibin B levels sufficiently discriminating to distinguish transient constitutional delay of growth and puberty (CDGP) from congenital hypogonadotropic hypogonadism (CHH) that affects reproductive health for life?
SUMMARY ANSWER
Both parameters lack the specificity to discriminate CDGP from CHH.
WHAT IS KNOWN ALREADY
GnRH tests and inhibin B levels have been proposed to differentiate CDGP from CHH. However, their diagnostic accuracies have been hampered by the small numbers of CHH included and enrichment of CHH patients with more severe forms.
STUDY DESIGN, SIZE, DURATION
The aim of this study was to assess the diagnostic performance of GnRH tests and inhibin B measurements in a large cohort of CHH male patients with the whole reproductive spectrum. From 2008 to 2018, 232 males were assessed: 127 with CHH, 74 with CDGP and 31 healthy controls.
PARTICIPANTS/MATERIALS, SETTING, METHODS
The participants were enrolled in two French academic referral centres. The following measurements were taken: testicular volume (TV), serum testosterone, inhibin B, LH and FSH, both at baseline and following the GnRH test.
MAIN RESULTS AND THE ROLE OF CHANCE
Among CHH patients, the LH response to the GnRH test was very variable and correlated with TV. Among CDGP patients, the LH peak was also variable and 47% of CHH patients had peak LH levels overlapping with the CDGP group. However, no patients with CDGP had an LH peak below 4.0 IU/l, while 53% CHH patients had LH peak below this threshold. Among CHH patients, inhibin B levels were also variable and correlated with TV and peak LH. Inhibin B was significantly lower in CHH patients than in CDGP patients but 50% of CHH values overlapped with CDGP values. Interestingly, all patients with CDGP had inhibin B levels above 35 pg/ml but 50% of CHH patients also had levels above this threshold.
LIMITATIONS, REASONS FOR CAUTION
As CHH is very rare, an international study would be necessary to recruit a larger CHH cohort and consolidate the conclusion reached here.
WIDER IMPLICATIONS OF THE FINDINGS
Peak LH and basal inhibin B levels are variable in both CHH and CDGP with significant overlap. Both parameters lack specificity and sensitivity to efficiently discriminate CHH from CDGP. This reflects the varying degree of gonadotropin deficiency inherent to CHH. These two diagnostic procedures may misdiagnose partial forms of isolated (non-syndromic) CHH, allowing them to be erroneously considered as CDGP.

Abstract
BACKGROUND: Structured transitional care (TC) is the planned, purposeful transfer from pediatric to adult care that aims to maintain high quality, developmentally appropriate continuous care. Relatively little is known about how endocrine TC is structured internationally, the process of TC and what outcomes are a priority for endocrine TC. This pilot study aimed to better understand endocrine TC and identify key elements for successful implementation internationally. METHODS: The Donabedian framework (structure-process-outcome) guided the international web-based survey examining TC programs for adolescents and young adults (AYAs) 16–25 years-old. The survey examined: 1) best practices i.e. six core elements of TC (Center for Health Care Transition Improvement ‘Got Transition’); 2) nursing involvement; 3) perceived importance of the ‘10 priority outcomes’ identified by an international multidisciplinary Delphi process (Fair et al. JAMA Pediatrics, 2016); and 4) promoters/barriers to implementation. Descriptive analysis was conducted for close-ended questions and thematic analysis for open-ended questions. Rankings by endocrine clinics were compared to the ‘10 priority outcomes’. RESULTS: Invitations were sent to authors of publications/posters on endocrine TC from the past 10 years. Eight responses were recorded from academic medical centers across seven countries with structured (n=3), semi-structured (n=2) and unstructured TC (n=3). Only 2/8 received institutional funding. Two practices involved nurses in assessing transition readiness and cited direct clinical care, therapeutic education and emotional support for AYAs/families as important contributions. Groups lacking nursing involvement expressed desire for a nursing role if financed. The most commonly used ‘Got Transition’ core elements were: providing supporting materials, confirming adult visit and consulting with adult providers. Only one group formally collected TC outcome data. “Self-management” was rated the most important TC outcome. “Understanding the condition/complications” and “attending medical appointments” were seen as having relatively higher priority for endocrine TC. Barriers related to lack of financial support and low institutional priority. Involving key stakeholders facilitated implementation. Having a dedicated nurse was noted as an opportunity for improving TC. CONCLUSIONS: Implementation of structured TC has been piecemeal and most practices do not fully utilize recommended best practices (‘Got Transition’). Few practices formally collect outcome data. The major perceived barrier to implementing TC is financial. Practices incorporating nurses value discipline-specific contributions. These pilot data point to a role for nursing in providing comprehensive, high quality, comprehensive care for AYAs with chronic endocrine conditions.

Abstract
CONTEXT The reproductive axis is controlled by a network of gonadotropin-releasing hormone (GnRH) neurons born in the primitive nose that migrate to the hypothalamus alongside axons of the olfactory system. The observation that congenital anosmia (inability to smell) is often associated with GnRH deficiency in humans led to the prevailing view that GnRH neurons depend on olfactory structures to reach the brain, but this hypothesis has not been confirmed. OBJECTIVE The objective of this work is to determine the potential for normal reproductive function in the setting of completely absent internal and external olfactory structures. METHODS We conducted comprehensive phenotyping studies in 11 patients with congenital arhinia. These studies were augmented by review of medical records and study questionnaires in another 40 international patients. RESULTS All male patients demonstrated clinical and/or biochemical signs of GnRH deficiency, and the 5 men studied in person had no luteinizing hormone (LH) pulses, suggesting absent GnRH activity. The 6 women studied in person also had apulsatile LH profiles, yet 3 had spontaneous breast development and 2 women (studied from afar) had normal breast development and menstrual cycles, suggesting a fully intact reproductive axis. Administration of pulsatile GnRH to 2 GnRH-deficient patients revealed normal pituitary responsiveness but gonadal failure in the male patient. CONCLUSIONS Patients with arhinia teach us that the GnRH neuron, a key gatekeeper of the reproductive axis, is associated with but may not depend on olfactory structures for normal migration and function, and more broadly, illustrate the power of extreme human phenotypes in answering fundamental questions about human embryology.

Abstract
Puberty is a remarkable period of postnatal development culminating in reproductive capacity. Biological changes of puberty are accompanied by social and emotional changes including psychosexual development. Developmental changes of adolescence are influenced by numerous biological, psychological and social influences. Work to date has identified associations between disrupted puberty (i.e. delayed, incomplete or absent) and psychosexual development. This brief review summarizes our current understanding of the psychosexual effects of delayed puberty and congenital hypogonadotropic hypogonadism (Kallmann syndrome). The importance of psychosocial support and transitional care is highlighted and future directions are discussed.

Abstract
Background Type 1 diabetes mellitus (T1DM) in children and adolescents is associated with significant cardiovascular morbidity and mortality. Early detection of vascular dysfunction is key to patient management yet current assessment techniques are invasive and not suitable for pediatric patient populations. A novel approach using isometric handgrip exercise during magnetic resonance imaging (IHE-MRI) has recently been developed to evaluate coronary endothelial function non-invasively in adults. This project aimed to assess endothelium-dependent coronary arterial response to IHE-MRI in children with T1DM and in age matched healthy controls. Materials and methods Healthy volunteers and children with T1DM (>5 years) were recruited. IHE-MRI cross-sectional coronary artery area measurements were recorded at rest and under stress. Carotid intima media thickness (CIMT) and aortic pulse wave velocity (PWV) were assessed for comparison. Student’s t-tests were used to compare results between groups. Results and discussion Seven children with T1DM (3 female, median 14.8 years, mean 14.8 ± 1.9 years) and 16 healthy controls (7 female, median 14.8 years, mean 14.2 ± 2.4 years) participated. A significant increase in stress-induced cross-sectional coronary area was measured in controls (5.4 mm2 at rest to 6.39 mm2 under stress, 18.8 ± 10.7%, p = 0.0004). In contrast, mean area change in patients with T1DM was not significant (7.17 mm2 at rest to 7.59 mm2 under stress, 10.5% ± 28.1%, p = n.s.). There was no significant difference in the results for neither PWV nor CIMT between patients and controls, (5.3±1.5 m/s vs.4.8±0.7 m/s and 0.4±0.03mm vs.0.46 mm ± 0.03 respectively, both p = n.s.). Conclusions Our pilot study demonstrates the feasibility of using a totally non-invasive IHE-MRI technique in children and adolescents with and without T1DM. Preliminary results suggest a blunted endothelium-dependent coronary vasomotor function in children with T1DM (>5 years). Better knowledge and new methodologies may improve surveillance and care for T1DM patients to reduce cardiovascular morbidity and mortality.

Abstract
CONTEXT Congenital hypogonadotropic hypogonadism/Kallmann syndrome (CHH/KS) is a rare condition characterized by gonadotropin deficiency and pubertal failure. Adult height (AH) in patients with CHH/KS has not been well studied. OBJECTIVE To assess AH in a large cohort of patients with CHH/KS. PATIENTS A total of 219 patients (165 males, 54 females). Parents and siblings were included. METHODS AH was assessed in patients and family members. AH was compared to the general French population, mid parental target height (TH) and between patients and same-sex siblings. Delta height (∆H) was considered as the difference between AH and parental TH. ∆H was compared between patients and siblings, normosmic CHH and KS (CHH with anosmia/hyposmia), and according to underlying genetic defect. We examined the correlations between ∆H and age at diagnosis and therapeutically induced individual statural gain. RESULTS Mean AH in men and women with CHH/KS was greater than that in the French general population. Patients of both sexes had AH > TH. Males with CHH/KS were significantly, albeit moderately, taller than their brothers. ∆H was higher in CHH/KS compared to unaffected siblings (+6.2 ± 7.2 cm vs +3.4 ± 5.2 cm, P < 0.0001). ∆H was positively correlated with age at diagnosis. Neither olfactory function (normosmic CHH vs KS) nor specific genetic cause impacted ∆H. Individual growth during replacement therapy inversely correlated with the age at initiation of hormonal treatment (P < 0.0001). CONCLUSIONS CHH/KS is associated with higher AH compared to the general population and mid-parental TH. Greater height in CHH/KS than siblings indicates that those differences are in part independent of an intergenerational effect.

Abstract
BACKGROUND Symptom perception in heart failure has recently been described as essential in the self-care process bridging self-care maintenance and self-care management. Accordingly, symptom perception appears to be critical for improving patient outcomes such as decreased hospital readmission and increased survival. OBJECTIVES To explore what interventions have been reported on heart failure symptom perception and to describe outcomes responsive to symptom perception. DESIGN We conducted a scoping review using PRISMA Extension for Scoping Reviews. DATA SOURCES Structured searches of Medline, PubMed, Embase, CINAHL, PsychINFO, Web of Science, Cochrane, Joanna Briggs Institute and Grey literature databases. REVIEW METHODS Two authors independently screened references for eligibility. Eligible articles were written in English, French, German, Swedish, Italian or Spanish and concerned symptom perception in adults with heart failure. Data were extracted and charted in tables by three reviewers. Results were narratively summarized. RESULTS We identified 99 eligible studies from 3055 references. Seven interventional studies targeted symptom perception as the single intervention component. Mixed results have been found: while some reported decreased symptom frequency, intensity and distress, enhanced health-related quality of life, improved heart failure self-care maintenance and management as well as a greater ability to mention heart failure symptoms, others found more contacts with healthcare providers or no impact on anxiety, heart failure self-care nor a number of diary reported symptoms. Additional interventional studies included symptom perception as one component of a multi-faceted intervention. Outcomes responsive to symptom perception were improved general and physical health, decreased mortality, heart failure decompensation, as hospital/emergency visits, shorter delays in seeking care, more consistent weight monitoring, improved symptom recognition as well as self-care management, decreased hospital length of stay and decreased costs. CONCLUSIONS While many studies allowed to map a comprehensive overview of interventions supporting symptom perception in heart failure as well as responsiveness to outcomes, only a few single component intervention studies targeting symptom perception have been reported and study designs preclude assessing intervention effectiveness. With regard to multiple component interventions, the specific impact of symptom perception interventions on outcomes remains uncertain to date. Well-designed studies are needed to test the effectiveness of symptom perception interventions and to elucidate relationships with outcomes.

Abstract
Background:Symptom perception in heart failure has been identified as crucial for effective self-care that is a modifiable factor related to decreased hospital readmission and improved survival.Aims:To review systematically the heart failure symptom perception literature and synthesise knowledge on definition, description, factors and instruments.Methods:We conducted a scoping review including studies reporting patient-reported symptom perception in adults with heart failure. Structured searches were conducted in Medline, PubMed, Embase, CINAHL, PsychINFO, Web of Science, Cochrane, JBI and grey literature. Two authors independently reviewed references for eligibility. Data were charted in tables and results narratively summarised.Results:The search yielded 3057 references, of which 106 were included. The definition of heart failure symptom perception comprised body listening, monitoring signs, recognising, interpreting and labelling symptoms, and furthermore awareness of and assigning meaning to the change. Symptom monitoring, recognition and interpretation were identified as challenging. Symptom perception facilitators include prior heart failure hospitalisation, heart failure self-care maintenance, symptom perception confidence, illness uncertainty and social support. Barriers include knowledge deficits, symptom clusters and lack of tools/materials. Factors with inconsistent impact on symptom perception include age, sex, education, experiences of living with heart failure, comorbidities, cognitive impairment, depression and symptom progression. One instrument measuring all dimensions of heart failure symptom perception was identified.Conclusion:Heart failure symptom perception definition and description have been elucidated. Several factors facilitating or hampering symptom perception are known. Further research is needed to determine a risk profile for poor symptom perception – which can then be taken into consideration when supporting heart failure self-care.

Abstract
Patients with peripheral artery disease (PAD) have increased risk for complications of cardiovascular disease. Smoking cessation, physical activity, and adherence to treatment are critical for limiting the progression of this chronic disease and improving health-related quality of life in patients with PAD.The aim of the study was to explore patient perceptions of PAD and views on medication, tobacco use, and physical activity. This descriptive, cross-sectional study included patients with PAD admitted to a vascular surgery unit at a tertiary academic medical center (October 2017 to January 2018). Sociodemographic data and medical information were collected during hospitalization. Patients completed the Brief Illness Perception Questionnaire, Beliefs about Medicines Questionnaire, and Cigarette Dependence Scale. Additional questions examined physical activity. In total, 32 patients participated in the study. About half (16/30) were active smokers, whereas the remainder had smoked in the past. Only half of patients (16/32) considered smoking as contributing to PAD. Most patients (18/30) perceived PAD as a chronic problem, yet 8/30 (27%) considered PAD a rather acute illness. Patients reported significant cognitive and emotional consequences of PAD (mean 6.2 ± 1.8 and 8.3 ± 2.9, maximum score 10, respectively). They rated relatively low perceived personal control (mean 4.8 ± 2.8, maximum score 10) and weak beliefs about the necessity of medication (mean 12.5 ± 3.3, maximum score 25). Most patients (21/32) perceived physical activity as a protective factor for PAD. Patients perceive PAD as having significant impact on their life and report low levels of personal control in managing PAD. Understanding patient health beliefs may inform more tailored therapeutic education and health promoting interventions to limit disease progression.

Abstract
We conducted a mixed-method study to examine coping response in BRCA+ women based on parent of origin (maternally vs paternally inherited BRCA mutation). Quantitative findings (n = 408) revealed paternally inherited cases had genetic testing later and were more likely to have a cancer diagnosis. Having a maternally inherited mutation was the strongest predictor of proactive risk management response. Qualitative interviews (n = 56) identified proactive responses among maternally inherited cases compared to reactive responses in paternally inherited cases. Findings underscore the importance of unbiased pedigree analysis to determine cancer risk. Women with paternally inherited BRCA mutations may benefit from additional psychosocial support.

Abstract
AIM The aim of the management of systemic sclerosis (MANOSS) study described in this protocol is to develop a chronic care model, based on a contextual analysis and stakeholder involvement, for patients living with the rare disease systemic sclerosis (SSc) in Switzerland. DESIGN Applying an implementation science approach, this study starts with an explanatory sequential mixed method study for contextual analysis, followed by broad stakeholder involvement for model development and a Delphi study to reach consensus. METHODS First, a quantitative cross-sectional survey with patients and healthcare professionals (HPs) will be conducted to identify current practice patterns of chronic illness management and technology readiness. Second, qualitative interviews with patients, family members and HPs will be performed to gain a deeper understanding of care needs identified in the quantitative survey. Third, a model of care will be co-created with input from patients, HPs and other experts. The eHealth enhanced Chronic Care Model will serve as a guiding framework. The new model and corresponding outcome parameters will be refined using a Delphi-study approach to reach consensus on a testable model of care for persons living with SSc. The protocol has received research ethics committee approval in September 2018 by the Swiss Ethics Committee. DISCUSSION The MANOSS study's participatory approach is essential for contextual fit of the model for patients with SSc in this setting. Subsequent feasibility testing and implementation are planned to evaluate the model's value in relation to health disparities faced by this patient population. IMPACT Patients living with this rare disease lack access to coordinated, specialized care and self-management support from qualified HPs. Reengineering of current care, with consideration for technological opportunities, is warranted to meet patients' and families' needs.

Abstract
CONTEXT After completion of puberty a subset of men experience functional hypogonadotropic hypogonadism (FHH) secondary to excessive exercise or weight loss. This phenomenon is akin to hypothalamic amenorrhea (HA) in women, yet little is known about FHH in men. OBJECTIVE To investigate the neuroendocrine mechanisms, genetics, and natural history underlying FHH. DESIGN Retrospective study in an academic medical center. PARTICIPANTS Healthy postpubertal men presenting with symptoms of hypogonadism in the setting of excessive exercise (>10 hours/week) or weight loss (>10% of body weight). Healthy age-matched men served as controls. INTERVENTIONS Clinical assessment, biochemical and neuroendocrine profiling, body composition, semen analysis, and genetic evaluation of genes known to cause isolated GnRH deficiency. MAIN OUTCOME MEASURES Reproductive hormone levels, endogenous GnRH-induced LH pulse patterns, and rare genetic variants. RESULTS Ten men with FHH were compared with 18 age-matched controls. Patients had significantly lower body mass index, testosterone, LH, and mean LH pulse amplitudes yet normal LH pulse frequency, serum FSH, and sperm counts. Some patients exhibited nocturnal, sleep-entrained LH pulses characteristic of early puberty, and one FHH subject showed a completely apulsatile LH secretion. After decreased exercise and weight gain, five men with men had normalized serum testosterone levels, and symptoms resolved. Rare missense variants in NSMF (n = 1) and CHD7 (n = 1) were identified in two men with FHH. CONCLUSIONS FHH is a rare, reversible form of male GnRH deficiency. LH pulse patterns in male FHH are similar to those observed in women with HA. This study expands the spectrum of GnRH deficiency disorders in men.

Abstract
OBJECTIVE Research findings on the relationship between serum androgens and adipose tissue in older females are inconsistent. We aimed to clarify the relationship using state-of-the-art techniques to evaluate associations between body fat distribution and plasma testosterone (T) levels in older postmenopausal women. DESIGN Observational, cross-sectional study of healthy, community dwelling postmenopausal women. PATIENTS AND MEASUREMENTS Postmenopausal women (60-80 years old) were included in this study. Overall body composition was evaluated by dual-energy X-ray absorptiometry. Abdominal and thigh fat depots were measured by magnetic resonance imaging. Circulating T concentrations were analysed by liquid chromatography-tandem mass spectrometry. RESULTS Thirty-five women (66.6 ± 0.8 years) participated in this study. T levels were positively associated with clinical proxy measures of adiposity including weight (ρ = 0.39), BMI (ρ = 0.43) and waist circumference (ρ = 0.39) (all P < 0.05). Fat mass and % body fat were correlated with T levels (ρ = 0.42 and 0.38 respectively, both P < 0.05). T correlated with overall and superficial abdominal fat (ρ = 0.34 and 0.37 respectively, both P < 0.05) but not with visceral adipose tissue. T increased with greater thigh fat (ρ = 0.49, P < 0.05) in both superficial and deep depots (ρ = 0.50 and 0.35 respectively, both P < 0.05). CONCLUSION Our results suggest that postmenopausal women with higher circulating T levels have both higher regional and overall body adiposity. These findings underscore the sexual dimorphism in the relationship between serum androgen levels and adiposity.

Abstract
Congenital hypogonadotropic hypogonadism (CHH) is a rare genetic disease characterized by absent puberty and infertility due to GnRH deficiency, and is often associated with anosmia [Kallmann syndrome (KS)]. The genetic etiology of CHH is heterogeneous, and more than 30 genes have been implicated in approximately 50% of patients with CHH. We hypothesized that genes encoding axon-guidance proteins containing fibronectin type-III (FN3) domains (similar to ANOS1, the first gene associated with KS), are mutated in CHH. We performed whole-exome sequencing in a cohort of 133 CHH probands to test this hypothesis, and identified rare sequence variants (RSVs) in genes encoding for the FN3-domain encoding protein deleted in colorectal cancer (DCC) and its ligand Netrin-1 (NTN1). In vitro studies of these RSVs revealed altered intracellular signaling associated with defects in cell morphology, and confirmed five heterozygous DCC mutations in 6 probands-5 of which presented as KS. Two KS probands carry heterozygous mutations in both DCC and NTN1 consistent with oligogenic inheritance. Further, we show that Netrin-1 promotes migration in immortalized GnRH neurons (GN11 cells). This study implicates DCC and NTN1 mutations in the pathophysiology of CHH consistent with the role of these two genes in the ontogeny of GnRH neurons in mice.
