The epidemiology of primary and secondary adrenal malignancies and associated adrenal insufficiency in hospitalised patients: an analysis of hospital admission data, NSW, Australia.

BACKGROUND: Adrenal insufficiency (AI) causes considerable morbidity but may remain undiagnosed in patients with adrenal malignancy (AM). The epidemiology of AI and adrenal crises (AC) in AM is uncertain. METHODS: This was a retrospective study examining hospital admission data from 2006 to 2017. All admissions to all hospitals in NSW, Australia over this period with a principal or comorbid diagnosis of an adrenal malignancy were selected. Data were examined for trends in admissions for AM and associated AI/AC using population data from the corresponding years. RESULTS: There were 15,376 hospital admissions with a diagnosis of AM in NSW over the study period, corresponding to 1281 admissions/year. The AM admission rate increased significantly over the study period from 129.9/million to 215.7/million (p < 0.01). An AI diagnosis was recorded in 182 (1.2%) admissions, corresponding to an average of 2.1/million/year. This rate increased significantly over the years of the study from 1.2/million in 2006 to 3.4/million in 2017 (p < 0.01). An AC was identified in 24 (13.2%) admissions with an AI diagnosis. Four patients (16.7%) with an AC died during the hospitalisation. CONCLUSION: Admission with a diagnosis of AM has increased over recent years and has been accompanied by an increase in AI diagnoses. While AI is diagnosed in a small proportion of patients with AM, ACs do occur in affected patients.

Flash Glucose Monitoring Compared to Capillary Glucose Levels in Patients With Diabetic Ketoacidosis: Potential Clinical Applications.

OBJECTIVE: Frequent, finger-prick capillary blood glucose measurement is standard care, used to drive insulin infusion rates for inpatients being resuscitated from diabetic ketoacidosis (DKA). Over recent years there has been a shift toward continuous interstitial glucose monitoring, allowing monitoring of glucose without repeated invasive testing. While continuous interstitial glucose monitoring has been safely and reliably utilized in the outpatient setting, it has yet to be studied in acutely unwell patients with DKA. The aim of this study, allowing for physiologically lower interstitial compared to capillary glucose, was to determine if interstitial flash glucose monitoring (FGM) would lead to insulin infusion rates that were similar to capillary blood glucose (CapBG) in DKA. METHODS: In this study, 10 patients with diabetes mellitus, assessed to be in DKA, were enrolled. At the same time as standard DKA management commencement, simultaneous FGM measurements were obtained. Duplicate paired glucose readings were then analyzed for agreement. RESULTS: Actual (CapBG-driven) and predicted (FGM determined) insulin infusion rates were similar. Minor differences in predicted insulin infusion rates were noted in 2/10 patients at higher glucose concentrations, which may relate to the lag in change in glucose in the interstitial space. CONCLUSION: Based on our results, a trial of clinical outcomes in patients with DKA treated with insulin infusion rates driven by CapBG versus subcutaneous FGM appears justified. The FGM method of testing may improve patient comfort, obviate fatigue, improve staff time and direct patient contact, and potentially facilitate rapid discharge.

The effect of patient-managed stress dosing on electrolytes and blood pressure in acute illness in children with adrenal insufficiency.

BACKGROUND: Adrenal crises (AC) are acute episodes of adrenal insufficiency (AI). Manifestations include hypotension and electrolyte disturbances. Glucocorticoid stress dosing (SD) can prevent AC progression, but its effect on physiological parameters has not been assessed in a 'real world setting'. AIMS: To assess the effect of prior self-managed glucocorticoid dose escalation on physiological markers in children with congenital adrenal hyperplasia (CAH) presenting to hospital for an acute illness. METHODS: An audit of records of all children with CAH presenting to paediatric referral hospital between 2000 and 2015. Potassium, sodium and glucose levels, and hypotension were compared between children who had and had not used SD. RESULTS: There were 321 attendances by patients with CAH and an acute illness during the study period. Any form of SD was used by 64.2% (n = 206); intramuscular (IM) hydrocortisone was used by 22.1% (n = 71) and oral only by 41.7% (n = 134). Use of SD (oral and/or IM) was associated with a significantly lower mean potassium level (4.02 ± 0.71 vs. 4.27 ± 0.79 mmol/l, P < .05). Linear regression analysis showed that age (beta: -0.04 years (95% CI -0.06, -0.02)), diarrhoea (beta: -0.41 (95% CI -0.06, -0.02)) and any form of stress dosing (oral, IM or both) (beta: -0.29 (95% CI -0.55, -0.04)) were each independently and significantly associated with potassium levels. SD was not significantly associated with sodium or glucose concentrations or with estimates of hypotension. CONCLUSION: Patient-initiated SD resulted in a significant reduction in hyperkalaemia and lowered mean potassium levels in paediatric patients with CAH but did not alter significantly sodium and glucose concentrations or incidences of hypotension.

Variations in the management of acute illness in children with congenital adrenal hyperplasia: An audit of three paediatric hospitals.

OBJECTIVE: Episodes of acute adrenal insufficiency (AI)/adrenal crises (AC) are a serious consequence of congenital adrenal hyperplasia (CAH). This study aimed to assess morbidity from acute illness in CAH and identify factors associated with use of IV hydrocortisone, admission and diagnosis of an AC. METHOD: An audit of acute illness presentations among children with CAH to paediatric hospitals in New South Wales, Australia, between 2000 and 2015. RESULTS: There were 321 acute presentations among 75 children with CAH. Two-thirds (66.7%, n = 214) of these resulted in admission and 49.2% (n = 158) of the patients received intravenous (IV) hydrocortisone. An AC was diagnosed in (9.0%). Prior to presentation, 64.2% (n = 206) had used oral stress dosing and 22.1% (n = 71) had been given intramuscular (IM) hydrocortisone. Vomiting was recorded in 61.1% (n = 196), 32.7% (n = 64) of whom had used IM hydrocortisone. Admission, AC diagnosis and use of stress dosing varied significantly between hospitals. IM use varied from 7.0% in one metropolitan hospital to 45.8% in the regional hospital. Children aged up to 12 months had the lowest levels of stress dosing and IV hydrocortisone administration. Higher numbers of prior hospital attendances for acute illness were associated with increased use of IM hydrocortisone. CONCLUSION: Prehospital and in-hospital management of children with CAH can vary between health services. Children under 12 months have lower levels of stress dosing prior to hospital than other age groups. Experience with acute episodes improves self-management of CAH in the context of acute illness in educated patient populations.

GLUCOCORTICOID-INDUCED ADRENAL INSUFFICIENCY: A STUDY OF THE INCIDENCE IN HOSPITAL PATIENTS AND A REVIEW OF PERI-OPERATIVE MANAGEMENT.

OBJECTIVE: Glucocorticoid (GC) pharmacotherapy is an effective treatment for a range of diseases, but exposure can suppress the hypothalamic-pituitary-adrenal axis, leading to glucocorticoid-induced adrenal insufficiency (GC-AI) in some patients. However, the incidence of diagnosed GC-AI and the associated health burden, including the incidence of adrenal crises (ACs), are unknown. Although GC-AI treatment is based on well-established principles, there are no agreed protocols regarding the peri-operative management of exposed patients. The aims of this study were to assess the incidence of diagnosed GC-AI in hospital patients and review current approaches to peri-operative management of surgical patients with GC exposure. METHODS: An analysis of hospital admission data concerning adult patients diagnosed with GC-AI and a review of published recommendations for peri-operative GC cover. RESULTS: Between 2001 and 2013, admission with a diagnosis of GC-AI in New South Wales, Australia was rare (annual average of 22.5 admissions/year) and ACs were even more rare (n = 3). Almost two-thirds (64.4%, n = 188) of the patients with diagnosed GC-AI were aged between 50 and 79 years and 45.2% (n = 132) had a comorbid infection. The current approach to peri-operative management of patients with GC exposure appears to be influenced by both the absence of clear guidelines and historic practices. This results in the exposure of some patients to supraphysiologic doses of GCs during the peri-operative period. CONCLUSION: Hospital admission with a diagnosis of GC-AI (with or without an AC) is very rare. Clear guidelines on peri-operative GC cover are necessary to avoid overreplacement with supraphysiologic doses in susceptible patients. ABBREVIATIONS: AC = adrenal crisis; ACTH = adrenocorticotropic hormone; AI = adrenal insufficiency; CI = confidence interval; GC = glucocorticoid; GC-AI = glucocorticoid-induced adrenal insufficiency; HPA = hypothalamic-pituitary-adrenal; OR = odds ratio.

Hospitalisation and comorbidities in Parkinson's disease: a large Australian retrospective study.

OBJECTIVES: Patients with Parkinson's disease (PD) require higher levels of care during hospitalisation. Management of comorbidities in these patients aims to optimise function while minimising complications. The objective of this study was to examine patterns of hospitalisation of patients with PD in NSW with regards to sociodemographic factors, comorbidities and aspects of clinical management. METHODS: A retrospective study of all patients with idiopathic PD and a control group of non-PD patients admitted for acute care to NSW hospitals between 2008 and 2012. RESULTS: The study group comprised 5637 cases and 8143 controls. The mean PD patient age was 75.0 years (±10.9). Patients with PD had a significantly longer hospital stay (median 7 days, IQR 3-13 vs 1 day, IQR 1-7, p<0.001) than control patients. Patients with PD were five times more likely to be treated for delirium, three times more likely to experience an adverse drug event and syncope, more than twice as likely to require management of falls/fractures, dementia, gastrointestinal complications, genitourinary infections, reduced mobility and other trauma but half as likely to require hospitalisation for chronic airways disease and neoplasia, including melanoma, than the control group (all p<0.001). CONCLUSIONS: Patients with PD are more likely to suffer serious health problems, including delirium, adverse drug reactions, syncope, falls and fractures than controls. These findings highlight PD as a multisystem neuropsychiatric disorder in which motor and non-motor features contribute to morbidity. Increased awareness of the added risk PD poses in acute hospitalised patients can be used to inform strategies to improve patient outcomes.

Recurrent nocturnal hypoglycaemia as a cause of morning fatigue in treated Addison's disease--favourable response to dietary management: a case report.

BACKGROUND: Addison's disease, or primary adrenal insufficiency, is often associated with reduced well-being and fatigue despite use of currently recommended adrenal hormone replacement. Hypoglycaemia is a known manifestation of glucocorticoid deficiency, but is generally considered rare in adults and not relevant to troubling ongoing symptoms in patients with Addison's disease. CASE PRESENTATION: A 43 year old woman with a three year history of Addison's disease complained of severe morning fatigue and headaches, despite standard glucocorticoid replacement therapy in the form of thrice daily hydrocortisone and mineralocorticoid replacement with fludrocortisone. Alternative glucocorticoid replacement regimens and the addition of dehydroepiandrosterone replacement therapy had no effect. Nocturnal hypoglycaemia was suspected and a 4-day continuous glucose monitor system (CGMS) revealed hypoglycaemia (interstitial glucose < 2.2 mmol/L) between 0200-0400 h on 3 of 4 days. The patient was counselled to take an evening snack designed to ensure slow absorption of ingested carbohydrates. Nocturnal hypoglycaemia was then absent on follow up CGMS assessment. The patient noted a marked symptomatic improvement in morning symptoms, but with persistent fatigue during the day. CONCLUSION: Currently, the best strategy for control of non-specific symptoms in treated Addison's disease is unknown, but it may be that investigation for hypoglycaemia and treatment, where necessary, could assist some sufferers to achieve improved wellbeing. A systematic study of this phenomenon in Addison's disease is required.

A descriptive study of adrenal crises in adults with adrenal insufficiency: increased risk with age and in those with bacterial infections.

BACKGROUND: An adrenal crisis (AC) is a major cause of morbidity in hypoadrenal patients. However, there is little information available on the incidence and underlying causes of AC. METHODS: The aim of the present study was to describe the incidence of AC in New South Wales (NSW), Australia. Using a health department database, we selected de-identified data on all adults aged 20 years and over who were treated in any hospital in NSW between July1, 2000-June 30, 2011, with either a principal or secondary diagnosis of an AC. AC admission rates were calculated overall and within age categories. Frequencies of co-morbid diagnoses were analysed by age and sex groups. Poisson regression was used to assess the significance of the observed change in AC related admissions with age, while controlling for any secular trends by including year in the model. Chi sq tests were used to assess the differences in frequencies of categorical variables between groups. RESULTS: 824 patients received treatment for an AC in hospital, corresponding to 74.9 admissions/year. The majority (62.5%) of the patients were women and 52.8% were aged 60 years and over. Admission rates were significantly associated with increasing age (p < 0.0001). Patients in the 60-69, 70-79 and 80+ age groups had the highest average admission rates (24.3, 35.2 and 45.8 per million/year). A principal or secondary diagnosis of an infection was reported in 317 (38.5%) patients and infection was significantly associated with age (p < 0.0001) with older patients having the highest proportion of cases. The most frequent infections were pneumonia/lower respiratory tract infection in 85 (10.3%) cases and urinary tract infection (UTI) in 82 (10.0%) patients. Women experienced 78.0% of the reported UTIs. There were 125 patients (15.2%) with an AC and a record of gastroenteritis. Twenty-six (3.2%) patients died in hospital but, of these, only 4 deaths (0.9%) were recorded among the 467 patients with a principal diagnosis of an AC. CONCLUSIONS: The incidence of AC increases with age. Infections, especially bacterial infections, are associated with the incidence of ACs and this increases with age.

Novel agents to treat adrenal insufficiency: findings of preclinical and early clinical trials.

INTRODUCTION: Adrenal insufficiency currently affects over 300/million population, with higher morbidity and mortality compared to the general population. Current glucocorticoid replacement therapy is limited by a lack of reliable biomarkers to guide dosing, inter-patient variation in metabolism and narrow therapeutic window. Increased morbidity and mortality may relate to unappreciated under- or over-exposure to glucocorticoids and impaired cortisol circadian rhythm. New agents are required to emulate physiological cortisol secretion and individualize glucocorticoid dosing. AREAS COVERED: History of glucocorticoid therapy, current limitations, and novel chronotherapeutic glucocorticoid delivery mechanisms. Literature search incorporated searches of PubMed and Embase utilizing terms such as adrenal insufficiency, Chronocort, Plenadren, continuous subcutaneous hydrocortisone infusion (CHSI), and glucocorticoid receptor modulator. EXPERT OPINION: Glucocorticoid chronotherapy is necessary to optimize glucocorticoid exposure and minimize complications. Current oral chronotherapeutics provide improved dosing functionality, but are modifiable only in specific increments and cannot accommodate ultradian cortisol variation. Current data show improvement in quality of life but not morbidity or mortality outcomes. CHSI has significant potential for individualized glucocorticoid dosing, but would require a suitable biomarker of glucocorticoid adequacy to be implementable. Avenues for future research include determining a glucocorticoid sufficiency biomarker, development of interstitial or systemic cortisol monitoring, or development of glucocorticoid receptor modulators.

The Changing Epidemiology of Adrenal Insufficiency: Iatrogenic Factors Predominate.

Context: Adrenal insufficiency (AI)-related morbidity persists despite efforts to minimize its effect. Reasons for this are unknown and warrant examination. Objective: This work aimed to investigate trends in AI hospitalizations and glucocorticoid (GC) replacement therapy use. Methods: Data on hospitalizations for a principal diagnosis of AI and prescriptions for short-acting GCs between 2000 and 2019 were extracted from national repositories. Age-standardized admission and prescription rates were calculated using census data. Rates were compared over time overall and according to age, sex, and disease subtype. Results: AI admissions increased by 62.0%, from 36.78/million to 59.59/million (trend P < .0001). Adrenal crisis (AC) admissions also increased, by 90.1% (from 10.73/million to 20.40/million; trend, P < .00001). These increases were more pronounced in the second decade. Prescriptions for short-acting GCs also increased (by 67.2%, from 2198.36/million in 2000/2001 to 3676.00/million in 2017/2018). Females had higher average admission rates and a greater increase in admission rates than males. Increased AI admissions were found in all age groups among females but only in men aged 70+ yrs. Secondary AI (SAI) admission rates increased by 91.7%, whereas admission rates for primary AI (PAI) remained unchanged. Conclusion: The prevalence of AI and hospitalizations for this disorder (including ACs) have increased since 2000, with a greater increase occurring after 2010. Admission rates for SAI increased but PAI admissions remained stable. Possible causes include immunotherapies for malignancy, increased cranial imaging detecting pituitary tumors and their subsequent treatment, and increased use of low-dose, short-acting GC-replacement therapy.

Tuberculosis of Adrenal Glands-A Population-based Case-control Study.

Purpose: Adrenal tuberculosis (ATB) can cause primary adrenal insufficiency (PAI) or may be misdiagnosed as nonfunctional adrenal tumors (NFATs) in patients with tuberculosis. Very little is known about its epidemiology in a modern, high-income setting. The aim was to investigate adrenal involvement and associated mortality in patients with tuberculosis. Methods: By using national registers, patients with tuberculosis and adrenal lesions were compared with controls without adrenal tumors. To analyze mortality in individuals with ATB or possible adrenal affection (ie, tuberculosis and NFAT), a subgroup of controls with tuberculosis was selected. The study population was included from 2005 to 2019 and followed until death or 2020. In mortality adjustments were made for age and sex. Results: Eight patients with ATB, 23 232 patients with NFAT, and 144 124 controls were included. Among those with NFAT, we found 34 with tuberculosis and NFAT. Among controls, 129 individuals diagnosed with tuberculosis were identified. The risk of having an adrenal tumor was increased in tuberculosis (odds ratio, 1.64; 95% CI, 1.12-2.39). Of those with ATB, 7 (88%) had PAI. One patient (3%) with tuberculosis and NFAT and 1 (0.8%) control with tuberculosis had PAI. Compared with controls with tuberculosis, mortality was increased in patients with ATB (hazard ratio, 5.4; 95% CI, 2.2-13.2; adjusted hazard ratio, 6.2; 95% CI, 2.5-15.6), and in patients with tuberculosis and NFAT (1.3; 0.6-2.7; 2.3; 1.1-5.1). PAI was a contributing factor in 4/6 (67%) deaths in patients with ATB. Conclusions: Tuberculosis with adrenal lesions was extremely rare. Most patients with ATB had PAI and mortality was increased.

Risk assessment, diagnosis, and treatment of cancer treatment-related adrenal insufficiency.

INTRODUCTION: Adrenal insufficiency (AI) is an easily treatable, potentially life-threatening condition, which is increasingly recognized in malignancy. The recent introduction of immune checkpoint inhibitors, in particular, and increasing use of tyrosine kinase inhibitors have increased the frequency of AI in patients with malignancy. A review is therefore warranted to summarize current knowledge on the topic and guide safe clinical practices. AREAS COVERED: Malignancy may directly impact the hypothalamic-pituitary-adrenal axis and cause AI, or their treatment including surgery, radiotherapy and medication. In this narrative review, we discuss new causes of AI, recognition of suggestive clinical features, diagnosis and subsequent treatment, aiming to avoid potentially fatal adrenal crisis (AC). Standard literature searching and authors assessment of clinical applicability were used. EXPERT OPINION: Adrenal insufficiency can be easily treated once identified but life threatening if unrecognized. While use of new agents such as immune checkpoint inhibitors (ICIs) is increasing, greater understanding of the mechanism of AI is needed to target prediction tools and enhance risk stratification.

Adrenal crises in adolescents and young adults.

PURPOSE: Review the literature concerning adrenal insufficiency (AI) and adrenal crisis (AC) in adolescents and young adults. METHODS: Searches of PubMed identifying relevant reports up to March 2022. RESULTS: AI is rare disorder that requires lifelong glucocorticoid replacement therapy and is associated with substantial morbidity and occasional mortality among adolescents and young adults. Aetiologies in this age group are more commonly congenital, with acquired causes, resulting from tumours in the hypothalamic-pituitary area and autoimmune adrenalitis among others, increasing with age. All patients with AI are at risk of AC, which have an estimated incidence of 6 to 8 ACs/100 patient years. Prevention of ACs includes use of educational interventions to achieve competency in dose escalation and parenteral glucocorticoid administration during times of physiological stress, such as an intercurrent infection. While the incidence of AI/AC in young children and adults has been documented, there are few studies focussed on the AC occurrence in adolescents and young adults with AI. This is despite the range of developmental, psychosocial, and structural changes that can interfere with chronic disease management during this important period of growth and development. CONCLUSION: In this review, we examine the current state of knowledge of AC epidemiology in emerging adults; examine the causes of ACs in this age group; and suggest areas for further investigation that are aimed at reducing the incidence and health impact of ACs in these patients.

Trends in hospital admissions for adrenal insufficiency in adolescents and young adults in the 21st century.

Background: Very little is known about the epidemiology of adrenal crises (AC) and adrenal insufficiency (AI) in adolescents and young adults. Methods: Data on all admissions to Australian hospitals between 2000/1 to 2019/20 for a principal diagnosis of AI (including AC) in 10-24 year olds were extracted from a national repository. Age and sex-specific rates and age-adjusted rates were compared. Findings: Over the study, there were 3386 admissions for a principal diagnosis of AI; 24.0% (n=812) were for an AC and 50·7% (n=1718) were for secondary AI. Age-adjusted AI admissions increased from 31·70/million in 2000/1 to 54·68/million in 2019/20 (p<0·0001). Age-adjusted AC admissions also increased, most notably in the second decade (from 5·80/million in 2010/11 to 15·75/million in 2019/20) (p<0·00001). Average AI and AC admission rates were comparable between the sexes, but rates increased significantly in females, especially in those aged 20 to 24 years, whose AC rate in 2019/20 (39·65/million) was significantly higher than the corresponding rate in 2000/1 (3·15/million) (p<0·00001). Average age-adjusted SAI admission rates were higher in males (23·92/million) than females (15·47/million) (p<0·00001). However, SAI admission rates increased only among females (from 11·81/million to 22·12/million in 2019/20), with an increase in 20-24 year old females in the second decade from 5·07/million in 2010 to 20·42/million (p<0·00001). Age adjusted admissions for congenital adrenal hyperplasia, primary AI (PAI) and drug-induced AI did not change significantly over the study. Interpretation: AC/AI admissions increased over the first two decades of this century in the emerging adult population, particularly among females who also experienced a marked increase in AC admission rates, most evident in the second decade. Although uncertain, possible explanations include: dose of glucocorticoid replacement; non-adherence to therapy; psychosocial factors; and difficulty in transition to adult services. Admissions for SAI also increased, while rates of PAI and CAH remained constant.

Corticosteroid-Binding Globulin Deficiency Independently Predicts Mortality in Septic Shock.

CONTEXT: Hydrocortisone administration in septic shock remains controversial. Corticosteroid-binding globulin (CBG) transports cortisol to inflammatory sites and is depleted in septic shock. OBJECTIVE: To determine whether severely deficient serum CBG < 200 nmol/L (reference range 269-641 nmol/L) independently predicts septic shock mortality. METHODS: A prospective observational study in patients with septic shock. Patients were categorized into 2 groups: mean plasma CBG concentrations <200 nmol/L and ≥200 nmol/L (day 1/2), with additional categorization by nadir CBG. Primary outcome was intensive care unit (ICU) mortality. Secondary outcomes were 28- and 90-day mortality, norepinephrine requirements, renal replacement therapy, and clinician-instituted hydrocortisone. RESULTS: 135 patients were included. Mortality rates in ICU were higher in the CBG < 200 nmol/L vs the CBG ≥ 200 nmol/L group: 32.4% vs 13.9% [odds ratio (OR) 2.97 (95% CI 1.19, 7.41); P = 0.02] with 28-day mortality OR 2.25 (95% CI 0.99, 5.11) and 90-day mortality OR 2.21 (95% CI 0.99, 4.91). Multivariate analysis revealed 4 factors independently associated with ICU mortality: CBG < 200 nmol/L (adjusted OR 3.23, 95% CI 1.06, 9.88), Acute Physiology and Chronic Health Evaluation II > 25 (adjusted OR 3.58, 95% CI 1.20, 10.68), Sequential Organ Failure Assessment (SOFA) liver score (adjusted OR 1.98, 95% CI 1.04, 3.72), and renal replacement therapy (adjusted OR 6.59, 95% CI 2.17, 20.01). Nadir CBG levels were associated with higher SOFA cardiovascular scores and norepinephrine total dose (µg; P < 0.01) and duration (days; P < 0.01). Plasma cortisol concentrations and hydrocortisone administration did not relate to ICU mortality. CONCLUSION: Septic shock patients with CBG < 200 nmol/L had higher norepinephrine requirements and 3.2-fold higher ICU mortality. CBG concentration was the only directly reversible independent mortality risk factor.

The effect of cognitive behavioral stress management on perceived stress, biological stress markers and weight loss/regain, from a diet-induced weight loss program: A randomized controlled trial.

Obesity and psychosocial stress are inter-related chronic conditions which lead to increased cardiovascular morbidity and mortality. The aim of this parallel randomized controlled trial was to determine whether the addition of a structured cognitive behavioral stress management (CBSM) on to a commercial online weight loss program, resulted in greater weight loss than the standard weight loss program in isolation. Eligible participants were adults between the ages 18-65, BMI 30-45 kg/m2, with no major systemic or psychiatric conditions. Seventy-four participants were assigned according to simple randomization using computer generated random numbers to either a 3-month online Weight Watchers® program (n = 36), or Weight Watchers® plus 10 weekly sessions of CBSM (n = 38). The primary outcome was weight at 3 months compared to baseline. Secondary outcomes were weight at 12 months and subjective/objective stress system measures and metabolic markers at 3 and 12 months. The study was powered at 90% to detect a 5 kg difference in weight between the two groups at 3 months. Independent sample t-tests were used to analyze the difference in weight (in kg) between the groups and paired sample t-tests were used to analyze the difference within group at different time intervals. At follow-up, there was no significant difference in weight loss between the groups (1.8 kg, 2.1 kg). However, CBSM was effective in reducing psychological measures of stress (p < 0.05) and salivary cortisol (waking, 20-min post-waking) at 3-months; with the effect on stress persisting at 12-months within the CBSM group. The reduction in PSS at 3 months was significantly greater in the CBSM group (3.84, p = 0.028) compared to WW only group at 3 months. Addition of CBSM to a standard weight loss intervention did not improve the weight loss over the standard approach on its own, but the CBSM intervention improved psychological stress parameters and cortisol secretion in participants living with obesity.

Interaction between hypotension and age on adrenal crisis diagnosis.

Objective: To determine whether adrenal crisis (AC) identification may be affected by the definition of hypotension. Context: Delays in AC diagnosis can result in adverse outcomes. AC-related cardiovascular compromise may vary according to baseline blood pressure and may be associated with delayed AC detection in some patients. Design: A retrospective study of paired systolic blood pressure (sBP) measurements in hospitalized patients with primary AI (PAI). Patients: Patients with PAI and an acute illness admitted for urgent treatment between 2000 and 2017. Measurements: A comparison between sBP on hospital arrival and on discharge. Hypotension was classified as either absolute hypotension (sBP 100mg or lower) or relative hypotension (sBP over 100 mg but at least 20 mm Hg lower than discharge sBP). Results: Of 152 admissions with paired blood pressure measurements, 46 (30.3%) included a medically diagnosed AC. Absolute hypotension was found in 38 (25.0%) records, and a further 21 (13.8%) patients were classified as having relative hypotension. Patients aged 65 years and older had the lowest (14.8%, n = 8) proportion with absolute hypotension but the highest (27.8%, n = 15) with relative hypotension. Use of either absolute or relative hypotension as the criterion for AC diagnosis increased the proportion of patients with an AC by 28.3% and the proportion of patients with an AC in the oldest age group by 130%. Conclusions: Failure to detect cardiovascular compromise is common in older AI patients, may underestimate the AC rate in this group, and delay essential treatment. Relative hypotension may play a role in AC diagnosis.
