In this paper, we discuss pediatric malnutrition in the context of protein-energy undernutrition and hidden hunger (single or multiple micronutrient deficiencies). Recent growth statistics show that nearly 150 million children under 5 years are stunted, and 50 million are wasted. At the same time, millions more children experience undernutrition of lesser severity but with negative effects on growth nonetheless. Beyond poor growth, such nutrient shortfalls can predispose children to impaired physical and mental development, which may have lifelong consequences. The World Health Organization recently set an aspirational goal “to end all forms of childhood malnutrition by 2030.”Plan of Action: Our paper proposes a stepwise strategy to raise awareness of childhood malnutrition risk and to work toward building a consensus on pediatric malnutrition screening as a pathway to ending childhood malnutrition. In a full plan for action, we propose to convene an expert Working Consensus Group on Pediatric Nutrition Screening (WCG-PNS). We propose that this group will work to (1) identify malnutrition screening tools specific for universal screening of children in hospital and community settings, (2) plan and lead healthcare professional training on how to screen for malnutrition risk, then take appropriate follow-up steps, (3) guide and advise quality improvement programs (QIPs) to facilitate incorporation of nutrition screening and interventions into everyday practice, and (4) measure and communicate potential findings in terms of health and financial outcomes.Conclusion: We recognize an urgent need for universal screening of infants and children for nutritional risk—around the world and across the continuum of care. Such screening is expected to promote early identification of children who can benefit from nutrition interventions, then ensure that these children get needed nutritional support. In this way, we aim to prevent growth impairment, which has also been associated with adverse effects on mental and physical development.Keywords: malnutrition, pediatrics, nutrition screening, nutritional interventions, undernutrition, clinical outcomes

The authors present the results from a study investigating identity management strategies among African-ancestral lesbians within their families of origin. The researchers collected qualitative data from 16 African-ancestral lesbians, which were analyzed using the CQR method. From these responses we examined themes relating to the comingout experiences, familial support patterns, and the integration and management of lesbian identities within African-ancestral families. We found that participants typically reported positive feelings and attitudes about themselves and their lesbian identities. Although levels of distress experienced during the coming-out process were mixed, our participants consistently endorsed the importance of relationships with family members as a means of more effectively managing their lesbian identities.

Objectives: The aim of this study was to compare the relative cost of a transesophageal echocardiography (TEE)-guided strategy versus conventional strategy for patients with atrial fibrillation (AF) >2 days duration undergoing electrical cardioversion over an eight-week period. Background: The Assessment of Cardioversion Using Transesophageal Echocardiography (ACUTE) trial found no difference in embolic rates between the two approaches. However, the TEE-guided strategy had a shorter time to cardioversion and a lower rate of composite bleeding. While similar clinical efficacy was concluded, the relative cost of these two strategies has not been explored. Methods: Two economic approaches were employed in the ACUTE trial. The first approach was based on hospital charge data from complete hospital Universal Billing Code of 1992 forms, a detailed hospital charge questionnaire, or imputation. Regression analysis was used to investigate the added cost of adverse events. The second economic approach involved the development of an independent analytic model simulating treatment and actual ACUTE outcome costs as a validation of clinically derived data. Sensitivity analysis was performed on the analytic model to investigate the potential range in cost differences between the strategies. Results: A total of 833 of the 1,222 patients were enrolled from 53 U.S. sites; TEE-guided (n = 420) and conventional (n = 413). At eight-week follow-up, total mean costs did not significantly differ between the two groups, respectively (6,508 dollars vs. 6,239 dollars; difference of 269 dollars; p = 0.50). Cumulative costs were 24% higher in the conventional group, primarily due to increased incidence of bleeding and hospital costs associated with bleeding. A separate analytic model showed that treatment costs were higher for the TEE-guided strategy, but outcome costs were higher for the conventional strategy. Sensitivity analysis of the analytic model illustrated that varying the incidence and cost of major bleeding and the cost of TEE had the greatest impact on cost differences between the two groups. Conclusions: In patients with AF >2 days duration undergoing electrical cardioversion, the TEE-guided group showed little difference in patient costs compared with the conventional group. The TEE strategy had higher initial treatment costs but lower outcome-associated costs. Cumulative costs were 24% higher in the conventional group, primarily due to bleeding. The TEE-guided strategy is an economically feasible approach compared with the conventional strategy. [ABSTRACT FROM AUTHOR]

In a multicenter randomized trial, we studied a transesophageal echocardiography (TEE) guided strategy with short-term anticoagulation compared with a conventional strategy for patients with atrial fibrillation >2 days' duration and undergoing cardioversion. Composite major and minor bleeding was a predetermined secondary end point of the study. The objective of the study was to assess the incidence, location, and predictors of bleeding in the 2 treatment groups. A total of 1,222 patients were assigned to a TEE guided or conventional strategy and followed over 8 weeks. We present data on major and minor adjudicated bleeding complications for the 2 study groups during the 8-week study period. Composite major and minor bleeding complications occurred in 51 of 1,222 patients (4.2%) and were significantly lower in the TEE guided group compared with the conventional group (2.9 vs 5.5%, p = 0.025). The TEE group had fewer cancellations of cardioversion as a result of bleeding (0% vs 0.7%, p = 0.003). Major (n = 14) and minor (n = 38) bleeding complications were predominantly gastrointestinal (71.4% and 31.6%, respectively) and were associated with warfarin use. Predictors of bleeding included patient age, conventional group assignment, inpatient status, and functional status. Thus, composite major and minor bleeding complications occurred in 4.2% of the 1,222 patients and were significantly lower in the TEE guided group compared with the conventional group. Treatment variables affecting length of anticoagulant therapy in the conventional arm combined with advancing age and functional status are important concerns in patients who undergo cardioversion of atrial fibrillation.

Transesophageal echocardiographic (TEE)-guided cardioversion of patients in atrial fibrillation (AF) of >2 days' duration is used as an alternative to conventional therapy. The purpose of this study was to investigate practice patterns employed for stroke prophylaxis in patients with AF who underwent cardioversion, and to determine the relative use of conventional and TEE-guided management strategies. We forwarded regionally stratified survey questionnaires to 947 clinical practices within the United States. The 10-question questionnaire queried demographic and clinical practice volumes and practices for managing patients with AF who underwent cardioversion. In addition, we used historical data to determine longitudinal use patterns of the TEE-guided approach for a large institution over 7 years. The 197 completed and returned surveys yielded a return rate of 20.8%. The TEE-guided approach was employed in approximately 12% of total cardioversions, but 75% of practices indicated that they employed transesophageal echocardiography only occasionally. The TEE-guided approach was associated with community size (r = 0.19; p<0.008), type of practice (r = 0.26; p = 0.001), total use of transesophageal echocardiography (r = 0.48; p<0.001), and volume of cardioversions (r = 0.28; p<0.001). Importantly, there was little consensus on the most appropriate clinical indications for TEE-guided cardioversions, and the proportions of TEE-guided cardioversion to total number of electrical cardioversions remained stable over 7 years. Practice volume and physician training may be the most important variables in the adoption of the TEE approach. [ABSTRACT FROM AUTHOR]

This study assesses how the newer modalities of tissue Doppler echocardiography and color M-mode flow propagation compare with respiratory variation of Doppler flow in distinguishing between constrictive pericarditis and restrictive cardiomyopathy. We studied 30 patients referred for further evaluation of diastolic function who had a diagnosis of constrictive pericarditis or restrictive cardiomyopathy established by diagnostic tests, including clinical assessment, magnetic resonance imaging, cardiac catheterization, endomyocardial biopsy, and surgical findings. Nineteen patients had constrictive pericarditis and 11 had restrictive cardiomyopathy. We performed 2-dimensional transesophageal echocardiography combined with pulsed-wave Doppler of the pulmonary veins and mitral inflow with respiratory monitoring, tissue Doppler echocardiography of the lateral mitral annulus, and color M-mode flow propagation of left ventricular filling. Respiratory variation of the mitral inflow peak early (peak E) velocity of > or =10% predicted constrictive pericarditis with 84% sensitivity and 91% specificity and variation in the pulmonary venous peak diastolic (peak D) flow velocity of > or =18% distinguished constriction with 79% sensitivity and 91% specificity. Using tissue Doppler echocardiography, a peak early velocity of longitudinal expansion (peak Ea) of > or =8.0 cm/s differentiated patients with constriction from restriction with 89% sensitivity and 100% specificity. A slope of > or =100 cm/s for the first aliasing contour in color M-mode flow propagation predicted patients with constriction with 74% sensitivity and 91% specificity. Thus, the newer methods of tissue Doppler echocardiography and color M-mode flow propagation are equivalent and complimentary with Doppler respiratory variation in distinguishing between constrictive pericarditis and restrictive cardiomyopathy. The additive role of the new methods needs to be established in difficult cases of constrictive pericarditis where respiratory variation may be absent or decreased. [ABSTRACT FROM AUTHOR]

Background: The purpose of this study was to evaluate opioid usage and prescribing trends among workers' compensation (WC) patients who underwent foot or ankle operative procedures compared with a control group., Methods: A retrospective review was conducted for WC and non-WC patients who underwent foot or ankle procedures in a single academic orthopaedic surgery practice. Outcome measures were total morphine milligram equivalents (MME) and number of opioid prescriptions., Results: A total of 118 patients were identified, including 51 patients in the WC group and 67 in the non-WC group. After index surgery, 67% (34 of 51) of WC patients had 2 or more additional opioid prescriptions compared to 39% (26 of 67) of non-WC patients (odds ratio [OR], 3.1; 95% confidence interval [CI], 1.4-6.7; P = .003). Collectively, there were greater prescriptions of oxycodone MME (P = .002) and hydrocodone MME (P = .07) in the WC cohort., Conclusions: Workers' compensation patients seem to be prescribed and consume opioids at a higher rate postoperatively. It is important for treating physicians to be aware of these trends, and discussions with patients regarding expected opioid use when planning surgical intervention may be beneficial. Physicians may need to set expectations preoperatively and suggest there are limits on the amount of opioids that can safely be prescribed., Level of Evidence: Level III, Retrospective cohort study, Prognostic ., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared the following potential conflicts of interest with respect to the research, authorship, and/or publication of this article: JD has been a consultant for Globus Medical Inc., Wright Medical Group, Stryker Corp., and Arthrex, Inc. in roles unrelated to this manuscript.

Arthroscopic anterior cruciate ligament (ACL) reconstruction has been the gold standard of care for ACL injuries for many years. Recently, there has been growing literature and interest in arthroscopic primary ACL repair in select patients with predominantly proximally based ACL tears. This Technical Note demonstrates a surgical technique that offers an efficient minimally invasive and physeal-sparing anatomic ACL repair with all-inside internal brace augmentation that in the short term has offered good results for our patients., Competing Interests: All authors (D.L.M., A.G.H., R.D.M., J.R.B.) declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (© 2024 The Authors.)

Injectable somatostatin receptor ligands (iSRL) are the most frequently utilized medical therapy in patients with acromegaly; however, satisfaction rates are suboptimal. Injections can result in local erythema, discomfort and subcutaneous nodule formation, encompassed with the inconvenience of attending either primary or secondary care medical facilities for injections every 4 weeks. Some patients also note breakthrough of acromegaly-related symptoms towards the end of the injection cycle. To improve acceptance and ultimately improve wellbeing of these individuals, two oral SRLs, oral octreotide capsules (OOC) and paltusotine, have been developed. The OOC combines an enteric coating to allow delivery to the small intestines and a transient permeability enhancer to enable oral bioavailability. Comparable octreotide levels are obtained with twice-daily OOC and subcutaneous octreotide 100 µg. Phase III studies show OOC to maintain equivalent biochemical control in at least 60% of patients previously receiving a stable dose of iSRL. In longer-term studies, the response to OOC was durable up to 3 years. Paltusotine is a novel potent orally available non-peptidyl somatostatin receptor subtype-2 ligand. Studies in healthy volunteers show dose-dependent suppression of growth hormone-releasing hormone-induced growth hormone secretion and suppression of insulin-like growth factor-I (IGF-I) with repeat doses. In the recent phase II study, patients with acromegaly who were partial responders (IGF-I 1.0 - 2.5 x upper limit of normal) to monotherapy with iSRL when switched to once-daily paltusotine maintained control of IGF-I within 20% of baseline or lower in 87% after 13 weeks. Adverse events with both OOC and paltusotine were reflective of those recognized with iSRL and occurred at a similar frequency. OOC and paltusotine are well-received additions to the therapeutic armamentarium in medical therapy for the management of acromegaly; however, further data on efficacy, tumour control and shrinkage are required to allow positioning of this medication within the management algorithm for acromegaly., Competing Interests: Disclosures: Robert D Murray has received research funding from Diurnal, Ipsen, Pfizer and Sandoz Pharma; lecture fees from Consilient, Ipsen, Novo Nordisk, Pfizer and Sandoz; and advisory board for Diurnal.

Background: A proportion of patients with adrenal insufficiency (AI) require increases in their maintenance glucocorticoids following the Covid-19 vaccine as a result of vaccine-related symptoms or development of incipient or frank adrenal crisis. In a large cohort of AI patients, we aim to characterise symptoms, changes in glucocorticoid dosage, occurrence of adrenal crises and whether there are differences between the mRNA and adenovirus vector vaccines., Patients and Methods: Patients with AI of any aetiology were invited to complete a short, structured questionnaire of their experience of the Covid-19 vaccination., Results: 279 of the 290 patients enrolled to this study fully completed the questionnaires. 176, 100 and 3 received the Astra Zeneca (AZ), Pfizer-BioNTech (PB) and Moderna (MD) as initial vaccine respectively; and for the second vaccine, 170, 99 and 10 received AZ, PB and MD respectively. Moderate to severe symptoms occurred in 44.8 and 39.7% after the first and second vaccines respectively, were of early onset (6.0 h, IQR 2-12 &. 6.0 h, IQR 2-24 h) and short duration (24 h, IQR 12-72 h & 26 h, IQR 12-72 h). 34.4 and 29.7% increased their maintenance glucocorticoid dose., Discussion: The Covid-19 vaccines appear well-tolerated in patients with AI, with similar frequency of symptoms to that reported in the background population. The AZ vaccine leads to slightly greater post-vaccination symptom burden and need to increase glucocorticoid dosage, but this does not translate to greater adverse outcomes., (© 2023.

Background: Patients with adrenal insufficiency (AI) have excess mortality, in part due to the occurrence of life-threatening adrenal crises. Infective processes, including that of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are recognised as the major precipitant of adrenal crises. Adverse reactions to the ChAdOx1 SARS-CoV-2 vaccine occur in a significant proportion of individuals, however, are mild-moderate in the majority of cases., Design: Case series., Patients & Results: We describe five cases where more severe adverse reactions to the ChAdOx1 SARS-CoV-2 vaccine led to actual or incipient adrenal crises requiring parenteral hydrocortisone within 24 h of receiving the first ChAdOx1 SARS-CoV-2 vaccination., Conclusion: In individuals with adrenal insufficiency, adverse reactions to the initial dose of the ChAdOx1 SARS-CoV-2 vaccination can precipitate adrenal crises. We recommend that patients with AI should immediately increase their maintenance glucocorticoid dosage 2-3 fold on experiencing any symptoms in the initial 24 h following vaccination., (© 2021 John Wiley & Sons Ltd.)

Multimodality cancer therapy has led to remarkable improvements in survival of childhood and young adult cancer, with survival rates exceeding 85%. Such remission rates come with their own adverse sequelea or 'late effects'. Although the cause of these late effects is multi-factorial, radiation-related adverse effects are one of the most prevalent. Hypopituitarism is a recognised complication of irradiation of brain tumours distant to the hypothalamo-pituitary (HP) axis when the axis is included within the exposed field. Much of the data concerning the development of hypopituitarism, however, relate to early forms of photon-based radiotherapy. In this narrative review, we discuss advances in individual radiotherapy techniques currently used in treating brain tumours and their theoretical benefits based primarily on dosimetric studies. Increasingly precise radiation techniques, including advances in the delivery of photons (i.e. intensity-modulated radiotherapy) and proton beam therapy, are now available options. The premise behind these newer techniques is to reduce the dose and volume of normal tissue irradiated whilst maintaining an effective radiation dose to target tissue. When treating brain tumours distant to the HP axis the expectation, based upon dosimetric studies, is that newer forms of radiotherapy will less frequently involve the HP axis in the exposed field, and where incorporated within the field it will be exposed to a lower radiotherapy dosage. Intuitively the dosimetric studies should translate into significant reductions in the prevalence of HP dysfunction. These data are promising; however, to date there are minimal robust clinical data to determine if the theoretical benefits of these newer techniques on HP dysfunction is to be realised.

Objective: The optimal approach to the surveillance of non-functioning pituitary microadenomas (micro-NFPAs) is not clearly established. Our aim was to generate evidence on the natural history of micro-NFPAs to support patient care., Design: Multi-centre, retrospective, cohort study involving 23 endocrine departments (UK NFPA consortium)., Methods: Clinical, imaging, and hormonal data of micro-NFPA cases between January, 1, 2008 and December, 21, 2021 were analysed., Results: Data for 459 patients were retrieved [median age at detection 44 years (IQR 31-57)-152 males/307 females]. Four hundred and nineteen patients had more than two magnetic resonance imagings (MRIs) [median imaging monitoring 3.5 years (IQR 1.71-6.1)]. One case developed apoplexy. Cumulative probability of micro-NFPA growth was 7.8% (95% CI, 4.9%-8.1%) and 14.5% (95% CI, 10.2%-18.8%) at 3 and 5 years, respectively, and of reduction 14.1% (95% CI, 10.4%-17.8%) and 21.3% (95% CI, 16.4%-26.2%) at 3 and 5 years, respectively. Median tumour enlargement was 2 mm (IQR 1-3) and 49% of micro-NFPAs that grew became macroadenomas (nearly all >5 mm at detection). Eight (1.9%) patients received surgery (only one had visual compromise with surgery required >3 years after micro-NFPA detection). Sex, age, and size at baseline were not predictors of enlargement/reduction. At the time of detection, 7.2%, 1.7%, and 1.5% patients had secondary hypogonadism, hypothyroidism, and hypoadrenalism, respectively. Two (0.6%) developed hypopituitarism during follow-up (after progression to macroadenoma)., Conclusions: Probability of micro-NFPA growth is low, and the development of new hypopituitarism is rare. Delaying the first follow-up MRI to 3 years and avoiding hormonal re-evaluation in the absence of tumour growth or clinical manifestations is a safe approach for micro-NFPA surveillance., Competing Interests: Conflicts of interest: None declared., (© The Author(s) 2023.

Background: Survivors of childhood brain tumours (SCBT) and teenage and young adult cancer survivors have an adverse cardiovascular risk profile, which translates into an increased vascular mortality. Data on cardiovascular risk profiles in SCBT are limited, and furthermore, there are no data in adult-onset (AO) brain tumours., Patients and: methods: Fasting lipids, glucose, insulin, 24-h blood pressure (BP), and body composition were measured in 36 brain tumour survivors (20 AO; 16 childhood-onset (CO)) and 36 age- and gender-matched controls., Results: Compared with controls, patients had elevated total cholesterol (5.3 ± 1.1 vs 4.6 ± 1.0 mmol/L, P = 0.007), LDL-C (3.1 ± 0.8 vs 2.7 ± 0.9 mmol/L, P = 0.011), insulin (13.4 ± 13.1 vs 7.6 ± 3.3 miu/L, P = 0.014), and increased insulin resistance (homeostatic model assessment for insulin resistance (HOMA-IR) 2.90 ± 2.84 vs 1.66 ± 0.73, P = 0.016). Patients showed adverse body composition, with increased total body fat mass (FM) (24.0 ± 12.2 vs 15.7 ± 6.6 kg, P < 0.001) and truncal FM (13.0 ± 6.7 vs 8.2 ± 3.7 kg, P < 0.001). After stratification by timing of onset, CO survivors showed significantly increased LDL-C, insulin, and HOMA-IR compared with controls. Body composition was characterized by the increased total body and truncal FM. Truncal fat mass was increased by 84.1% compared with controls. AO survivors showed similar adverse cardiovascular risk profiles, with increased total cholesterol and HOMA-IR. Truncal FM was increased by 41.0% compared with matched controls (P = 0.029). No difference in mean 24-h BP was noted between patients and controls irrespective of the timing of cancer diagnosis., Conclusion: The phenotype of both CO and AO brain tumour survivors is characterized by an adverse metabolic profile and body composition, putatively placing long-term survivors at increased risk of vascular morbidity and mortality.

Introduction: Surgical site infections (SSIs) are associated with patient morbidity and increased healthcare costs. Limited literature in foot and ankle surgery provides guidance about routine administration of postoperative antibiotic prophylaxis. The purpose of this study was to examine the incidence and revision surgery rates of SSI in outpatient foot and ankle surgeries in patients not receiving oral postoperative antibiotic prophylaxis., Methods: A retrospective review of all outpatient surgeries (n = 1517) conducted by a single surgeon in a tertiary referral academic center was conducted through electronic medical records. Incidence of SSI, revision surgery rate, and associated risk factors were determined. The median follow-up was 6 months., Results: Postoperative infection occurred in 2.9% (n = 44) of the surgeries conducted, with 0.9% of patients (n = 14) requiring return to the operating room. Thirty patients (2.0%) were diagnosed with simple superficial infections, which resolved with local wound care and oral antibiotics. Diabetes (adjusted odds ratio, 2.09; 95% confidence interval, 1.00 to 4.38; P = 0.049) and increasing age (adjusted odds ratio, 1.02; 95% confidence interval, 1.00 to 1.04; P = 0.016) were significantly associated with postoperative infection., Discussion: This study demonstrated low postoperative infection and revision surgery rates without the routine prescription of prophylactic postoperative antibiotics. Increasing age and diabetes are signficant risk factors for developing a postoperative infection., (Copyright © 2023 The Authors.

The aim of this study is to characterise somatostatin analogue-responsive headache in acromegaly, hitherto not systematically documented in a significant cohort. Using the UK pituitary network, we have clinically characterised a cohort of 18 patients suffering from acromegaly-related headache with a clear response to somatostatin analogues. The majority of patients had chronic migraine (78%) as defined by the International Headache Society diagnostic criteria. Headache was present at the time of acromegaly presentation and clearly associated temporally with disease activity in all cases. Short-acting somatostatin analogues uniquely resolved pain within minutes and the mean duration of analgesia was 1-6 h. Patients on long-acting analogues required less short-acting injections (mean: 3.7 vs 10.4 injections per day, P = 0.005). 94% used somatostatin analogues to control ongoing headache pain. All patients presented with macroadenoma, most had incomplete resection (94%) and headache was ipsilateral to remnant tissue (94%). Although biochemical control was achieved in 78% of patients, headache remained in 71% of them. Patients selected for this study had ongoing headache post-treatment (mean duration: 16 years after diagnosis); only four patients reached headache remission 26 years (mean range: 14-33) after the diagnosis. Headache in acromegaly patients can be persistent, severe, unrelieved by surgery, long-lasting and uncoupled from biochemical control. We show here that long-acting analogues allow a decrease in the number of short-acting analogue injections for headache relief. Further studies are needed to understand the mechanisms, markers and tumour tissue characteristics of acromegaly-related headache. Until then, this publication serves to provide the clinical characteristics as a reference point for further study.

Endocrine disorders in survivors of childhood, adolescent, and young adult (CAYA) cancers are associated with substantial adverse physical and psychosocial effects. To improve appropriate and timely endocrine screening and referral to a specialist, the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) aims to develop evidence and expert consensus-based guidelines for healthcare providers that harmonize recommendations for surveillance of endocrine disorders in CAYA cancer survivors. Existing IGHG surveillance recommendations for premature ovarian insufficiency, gonadotoxicity in males, fertility preservation, and thyroid cancer are summarized. For hypothalamic-pituitary (HP) dysfunction, new surveillance recommendations were formulated by a guideline panel consisting of 42 interdisciplinary international experts. A systematic literature search was performed in MEDLINE (through PubMed) for clinically relevant questions concerning HP dysfunction. Literature was screened for eligibility. Recommendations were formulated by drawing conclusions from quality assessment of all evidence, considering the potential benefits of early detection and appropriate management. Healthcare providers should be aware that CAYA cancer survivors have an increased risk for endocrine disorders, including HP dysfunction. Regular surveillance with clinical history, anthropomorphic measures, physical examination, and laboratory measurements is recommended in at-risk survivors. When endocrine disorders are suspected, healthcare providers should proceed with timely referrals to specialized services. These international evidence-based recommendations for surveillance of endocrine disorders in CAYA cancer survivors inform healthcare providers and highlight the need for long-term endocrine follow-up care in subgroups of survivors and elucidate opportunities for further research., (© The Author(s) 2021.

Background: Radiotherapy is a valuable treatment in the management algorithm of pituitary adenomas and craniopharyngiomas. However, the risk of second brain tumour following radiotherapy is a major concern. We assessed this risk using non-irradiated patients with the same primary pathology and imaging surveillance as controls., Methods: In this multicentre, retrospective cohort study, 4292 patients with pituitary adenoma or craniopharyngioma were identified from departmental registries at six adult endocrine centres (Birmingham, Oxford, Leeds, Leicester, and Bristol, UK and Ferrara, Italy). Patients with insufficient clinical data, known genetic predisposition to or history of brain tumour before study entry (n=532), and recipients of proton beam or stereotactic radiotherapy (n=81) were excluded. Data were analysed for 996 patients exposed to 2-dimensional radiotherapy, 3-dimensional conformal radiotherapy, or intensity-modulated radiotherapy, and compared with 2683 controls., Findings: Over 45 246 patient-years, second brain tumours were reported in 61 patients (seven malignant [five radiotherapy, two controls], 54 benign [25 radiotherapy, 29 controls]). Radiotherapy exposure and older age at pituitary tumour detection were associated with increased risk of second brain tumour. Rate ratio for irradiated patients was 2·18 (95% CI 1·31-3·62, p<0·0001). Cumulative probability of second brain tumour was 4% for the irradiated and 2·1% for the controls at 20 years., Interpretation: Irradiated adults with pituitary adenoma or craniopharyngioma are at increased risk of second brain tumours, although this risk is considerably lower than previously reported in studies using general population controls with no imaging surveillance. Our data clarify an important clinical question and guide clinicians when counselling patients with pituitary adenoma or craniopharyngioma on the risks and benefits of radiotherapy., Funding: Pfizer., Competing Interests: Declaration of interests AC has received a grant from Health Education England for a radiotherapy contouring analysis website tool in 2020.

The first 1000 days is a critical window to optimize nutrition. Young children, particularly 12-24 month-olds, are an understudied population. Young children have unique nutrient needs and reach important developmental milestones when those needs are met. Intriguingly, there are differences in the dietary patterns and recommendations for young children in the US vs. globally, notably for breastfeeding practices, nutrient and food guidelines, and young child formulas (YCFs)/toddler drinks. This perspective paper compares these differences in young child nutrition and identifies both knowledge gaps and surveillance gaps to be filled. Parental perceptions, feeding challenges, and nutrition challenges are also discussed. Ultimately, collaboration among academia and clinicians, the private sector, and the government will help close young child nutrition gaps in both the US and globally.
