Clinical significance of an elevated on-admission beta-hydroxybutyrate in acutely ill adult patients without diabetes. Emerg Med Australas 2024. [PMID: 38439135 DOI: 10.1111/1742-6723.14393] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2023] [Revised: 02/06/2024] [Accepted: 02/14/2024] [Indexed: 03/06/2024]
Abstract
OBJECTIVE To determine the relationship between point-of-care β-hydroxybutyrate (BHB) concentration and outcomes in adult patients without diabetes admitted through ED. METHODS This was a prospective study from 10 March to 2 July 2021. Admitted patients without diabetes had capillary BHB sampled in ED. Outcomes of length-of-stay (LOS), composite mortality/ICU admission rates and clinical severity scores (Quick Sepsis Organ Failure Assessment score/National Early Warning Score [qSOFA/NEWS]) were measured. BHB was assessed as a continuous variable and between those with BHB above and equal to 1.0 mmol/L and those below 1.0 mmol/L. RESULTS A total of 311 patients were included from 2377 admissions. Median length-of-stay was 4.1 days (IQR 2.1-9.8), 18 (5.8%) died and 37 (11.8%) were admitted to ICU. Median BHB was 0.2 mmol/L (IQR 0.1-0.4). Twenty-five patients had BHB ≥1.0 mmol/L and five were >3.0 mmol/L. There was no significant difference in median LOS for patients with BHB ≥1.0 mmol/L compared to non-ketotic patients, 5.3 days (IQR 2.2-7.5) versus 4.1 days, respectively (IQR 2.0-9.8) (P = 0.69). BHB did not correlate with LOS (Spearman ρ = 0.116, 95% confidence interval: 0.006-0.223). qSOFA and NEWS also did not differ between these cohorts. For those 25 patients with BHB ≥1.0 mmol/L, an infective/inflammatory diagnosis was present in 11 (44%), at least 2 days of fasting in 10 (40%) and ethanol intake >40 g within 48 h in 4 (16%). CONCLUSIONS Routine BHB measurement in patients without diabetes does not add to clinical bedside assessment and use should be limited to when required to confirm a clinical impression.

Decreased rates of hospital-acquired infection after introduction of an active surveillance, virtual glucose management system. Diabetes Res Clin Pract 2023; 203:110880. [PMID: 37591345 DOI: 10.1016/j.diabres.2023.110880] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 06/30/2023] [Accepted: 08/14/2023] [Indexed: 08/19/2023]
Abstract
Addition of an active surveillance virtual glucose management (VGM) system to usual consultation-based diabetes inpatient care at our hospital was associated with a decrease in hospital-acquired infection from 8.7% (17/196) to 3.5% (6/172) with an adjusted odds ratio of 0.17 (95%CI: 0.05-0.61), and a reduction in hypoglycemic and hyperglycemic patient-stay days.

What is the utility of blood beta-hydroxybutyrate measurements in emergency department in patients without diabetes: a systematic review. Syst Rev 2023; 12:71. [PMID: 37118837 PMCID: PMC10140707 DOI: 10.1186/s13643-023-02203-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Accepted: 02/26/2023] [Indexed: 04/30/2023] Open
Abstract
BACKGROUND Ketones are synthesised as an alternative fuel source during times of energy restriction. In the absence of a hyperglycemic emergency, ketosis in patients presenting to the emergency department (ED) may indicate reduced carbohydrate intake. In the perioperative setting, excess fasting with ketosis is associated with worse outcomes; however, whether ketosis in patients without diabetes presenting to ED is also associated with worse outcomes is unclear. This systematic review aims to examine the evidence for ketosis in predicting the need for hospital admission in patients without diabetes, presenting to the ED. METHODS A systematic review was performed using PRISMA guidelines. We searched electronic bases (OVID-Medline, OVID-EMBASE, Scopus and PubMed) up to December 2022. Eligible studies included children or adults without diabetes presenting to the ED where a point-of-care capillary beta-hydroxybutyrate (BHB) was measured and compared to outcomes including the need for admission. Outcome measures included need for admission and length of stay. Content analysis was performed systematically; bias and certainty assessed using standard tools. RESULTS The literature search found 17,133 citations, 14,965 papers were subjected to title and abstract screening. The full text of 62 eligible studies were reviewed. Seven articles met the inclusion criteria. Six studies were conducted solely in the paediatric population, and of these, four were limited to children presenting with gastroenteritis symptoms. Median BHB was higher in children requiring hospital admission with an AUC of 0.64-0.65 across two studies. There was a weak correlation between BHB and dehydration score or duration of symptoms. The single study in adults, limited to stroke presentations, observed no relationship between BHB and neurological deficit at presentation. All studies were at risk of bias using the Newcastle-Ottawa Scale and was assessed of "very low" to "low" quality due to their study design in the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Heterogeneity amongst selected studies precluded meta-analysis. CONCLUSION The evidence for any utility of BHB measurement in the ED in absence of diabetes is limited to the paediatric population, specifically children presenting with symptoms of gastroenteritis. Any role in adults remains unexplored.

Continuous glucose monitoring to assess glucose variability in type 3c diabetes. Diabet Med 2022; 39:e14882. [PMID: 35569007 PMCID: PMC9545045 DOI: 10.1111/dme.14882] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 05/12/2022] [Indexed: 11/28/2022]
Abstract
AIM The effectiveness of continuous glucose monitoring (CGM) in maintaining glycaemic control in type 1 diabetes mellitus and type 2 diabetes mellitus has been well demonstrated. However, the degree of glycaemic variability (GV) in people with type 3c diabetes mellitus has not been fully explored using CGM. This study aims to evaluate GV in type 3c diabetes mellitus participants and compare it to type 1 diabetes mellitus and type 2 diabetes mellitus. METHODS Participants were grouped according to type of diabetes. GV, defined as percentage coefficient of variation (%CV), and other glycaemic indices were obtained using CGM (FreeStyle Libre, Abbott, Australia) from 82 participants across all three cohorts over a 14-day period. Comparison of baseline characteristics and GV were performed across all groups. Correlation of GV with C-peptide values, and whether pancreatic supplementation had an effect on GV were also assessed in the type 3c diabetes mellitus cohort. RESULTS GV of type 3c diabetes mellitus participants was within the recommended target of less than %CV 36% (p = 0.004). Type 3c diabetes mellitus participants had the lowest GV among the three groups (p = 0.001). There was a trend for lower C-peptide levels to be associated with higher GV in type 3c diabetes mellitus participants (p = 0.22). Pancreatic enzyme supplementation in type 3c diabetes mellitus participants did not have an effect on GV (p = 0.664). CONCLUSIONS Although type 3c diabetes mellitus participants were the least variable, they had the highest mean glucose levels and estimated HbA1c , which suggests that the concept of 'brittle' diabetes in type 3c diabetes mellitus is not supported by the results of CGM in this study and may be leading to poorer glycaemic control.

Acceptance and Effect of Continuous Glucose Monitoring on Discharge From Hospital in Patients With Type 2 Diabetes: Open-label, Prospective, Controlled Study. JMIR Diabetes 2022; 7:e35163. [PMID: 35532995 PMCID: PMC9127644 DOI: 10.2196/35163] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2021] [Revised: 02/08/2022] [Accepted: 04/08/2022] [Indexed: 11/13/2022] Open
Abstract
Background Continuous glucose monitors (CGM) can provide detailed information on glucose excursions. There is little information on safe transitioning from hospital back to the community for patients who have had diabetes therapies adjusted in hospital and it is unclear whether newer technologies may facilitate this process. Objective Our aim was to determine whether offering CGM on discharge would be acceptable and if CGM initiated on hospital discharge in people with type 2 diabetes (T2DM) would reduce hospital re-presentations at 1 month. Methods This was an open-label study. Adult inpatients with T2DM, who were to be discharged home and required postdischarge glycemic stabilization, were offered usual care consisting of clinic review at 2 weeks and at 3 months. In addition to usual care, participants in the intervention arm were provided with a Libre flash glucose monitoring system (Abbott Australia). An initial run-in phase for the first 20 participants was planned, where all consenting participants were enrolled in an active arm. Subsequently, all participants were to be randomized to the active arm or usual care control group. Results Of 237 patients screened during their hospital admission, 34 had comorbidities affecting cognition that prevented informed consent and affected their ability to learn to use the CGM device. In addition, 21 were not able to be approached as the material was only in English. Of 101 potential participants who fulfilled eligibility criteria, 19 provided consent and were enrolled. Of the 82 patients who declined to participate, 31 advised that the learning of a new task toward discharge was overwhelming or too stressful and 26 were not interested, with no other details. Due to poor recruitment, the study was terminated without entering the randomization phase to determine whether CGM could reduce readmission rate. Conclusions These results suggest successful and equitable implementation of telemedicine programs requires that any human factors such as language, cognition, and possible disengagement be addressed. Recovery from acute illness may not be the ideal time for introduction of newer technologies or may require more novel implementation frameworks.

Abstract
AIM Our aim was to determine the relationship between glucose and lactate amongst adult patients admitted to hospital via the emergency department. METHOD We performed a cross-sectional observational study of 2541 patients admitted via the emergency department who had an admission glucose and lactate measurement available. RESULTS 23% of the whole cohort had a diagnosis of diabetes. Glucose and lactate were predictors of the primary outcome of critical illness defined as composite of intensive care unit (ICU) admission or in-hospital death. In the multivariable analysis, lactate but not glucose remained an independent predictor of ICU/in hospital death in the group without diabetes. In the diabetes group, both glucose and lactate remained independent predictors of ICU admission/ in-hospital death. CONCLUSIONS Hyperglycaemia and hyperlactataemia are part of the metabolic response to critical illness. Lactate and a diagnosis of diabetes modify the relationship between glycaemia and critical illness.

Abstract
AIM To determine the relationship between bone microarchitecture, as measured by trabecular bone score, and advanced glycation end-product accumulation, as assessed by skin autofluorescence. METHODS This was a cross-sectional study. Participants were 64 post-menopausal women with type 2 diabetes and 175 post-menopausal women without diabetes. Trabecular bone score and skin autofluorescence data were obtained at time of bone density measurement. RESULTS Trabecular bone score and skin autofluorescence were inversely correlated in women with type 2 diabetes (r = -0.34, P = 0.006); no correlation was seen in post-menopausal women without diabetes (r = -0.029, P = 0.707). After adjustment, neither skin autofluorescence nor a diagnosis of diabetes were associated with trabecular bone score, but HbA1c and waist circumference were independently associated with trabecular bone score. CONCLUSION Skin autofluorescence did not predict trabecular bone score. In contrast, glycaemia, as reflected by HbA1c , and visceral adiposity, as reflected by waist circumference, were independently associated with trabecular bone score.

Abstract
BACKGROUND The development of pancreatogenic diabetes mellitus (PDM) is a common complication post-pancreatectomy; however, its prevalence has not been described in Australia. We aimed to describe the glycaemic status pre- and post-pancreatectomy, compare patients' clinical characteristics, group according to pre- and post-pancreatectomy diabetes mellitus (DM) status and identify predictors of post-operative PDM. METHODS We retrospectively reviewed the medical records of patients admitted for pancreatic resection at a single institution from 2011 to 2017. Post-operative DM status was determined at the time of discharge or at 30 days post-operation. Longer term DM onset was as documented in medical record subsequent to admission for pancreatic surgery. RESULTS A total of 137 cases were analysed; 13.3% and 24.8% of patients developed post-operative PDM within 30 days and at median of 1 year (range 1-4 years) follow-up, respectively. All patients with pre-existing DM continued to have DM post-operatively. Patients with pre-existing DM were older (P = 0.004) and had a family history of DM (P = 0.020); 8.3% of patients who had undergone pancreaticoduodenectomy versus 17.1% of patients who had undergone distal pancreatectomy developed PDM (P = 0.318). A lower estimated glomerular filtration rate (P = 0.033) was significantly associated with post-operative PDM development. No independent predictors for post-operative PDM were identified. CONCLUSIONS The new development of DM within 30 days post-pancreatectomy occurs in approximately one in seven persons. No patients with pre-existing DM demonstrated a remission of DM post-pancreatectomy. These findings suggest that all patients should be screened for DM pre-operatively and followed up post-operatively, particularly those with pre-existing impaired renal function.

The Significance of an Increased Beta-Hydroxybutyrate at Presentation to the Emergency Department in Patients with Diabetes in the Absence of a Hyperglycemic Emergency. J Diabetes Res 2019; 2019:7387128.

Abstract
The significance of hyperketonemia in adults with diabetes presenting to the emergency department with acute illness, not due to a diabetic hyperglycemic emergency, has not been well characterized. Adult patients with diabetes presenting to the emergency department who had venous blood gas and beta-hydroxybutyrate levels measured whilst in the emergency department were retrospectively evaluated for the relationship between BHB and clinical outcomes. Over 6 months, 404 patients with diabetes had at least one beta-hydroxybutyrate level measured in the emergency department. There were 23 admissions for diabetic ketoacidosis (DKA) or hyperosmolar state. Of the remainder, 58 patients had a beta-hydroxybutyrate ≥ 1 mmol/L; this group had a higher glucose at presentation (19.0 (8.8) versus 10.4 (9.9) mmol/L), higher HbA1c (8.8 (5.4) versus 8.0 (3.3)%), lower bicarbonate (22.6 (6.2) versus 24.8 (4.7) mmol/L), and higher anion gap (14.8 (6.1) versus 12.6 (4.2)) than had those with BHB < 1 mmol/L. There was no association between the presence of ketosis and the length of stay (4.2 (7.3) versus (3.0) (7.2) days). Acute illness in those with diabetes associated with ketosis in the absence of DKA is associated with worse glycaemic control than in those without ketosis. Ketosis may represent an intermediate state of metabolic dysregulation rather than being associated with a more severe acute illness, as suggested by no relationship between BHB and length of stay.

Abstract
Background. Optimal glycaemic targets following transplantation are unknown. Understanding the impact of DM and posttransplant diabetes mellitus (PTDM) may improve patient and graft survival in transplant recipients. Aim. To determine the perioperative and one-year outcomes after renal transplantation and whether these outcomes are affected by preexisting DM, PTDM, or glycaemia during transplant admission. Method. Adult recipients of renal transplants from a single centre over 5.5 years were retrospectively reviewed. Measured outcomes during transplant admission included glycaemia and complications (infective complications, acute rejection, and return to dialysis) and, at 12 months, glycaemic control and complications (cardiovascular complication, graft failure). Results. Of 148 patients analysed, 29 (19.6%) had DM and 27 (18.2%) developed PTDM. Following transplantation, glucose levels were higher in patients with DM and PTDM. DM patients had a longer hospital stay, had more infections, and were more likely return to dialysis. PTDM patients had increased rates of acute rejection and return to dialysis. At 1 year after transplant, there were more cardiovascular complications in DM patients compared to those without DM. Conclusions. Compared to patients without DM, patients with DM or PTDM are more likely to suffer from complications perioperatively and at 12 months. Perioperative glycaemia is associated with graft function and may be a modifiable risk.

Urine albumin-creatinine ratio in women with gestational diabetes: its link with glycaemic status. Aust N Z J Obstet Gynaecol 2014; 54:529-33.

Abstract
BACKGROUND Micro-albuminuria has been established as a marker for micro-vascular disease. Spot urine albumin-to-creatinine ratio (UACR), even in the high normal range, predicts future cardiovascular events. The value of UACR in women with gestational diabetes mellitus (GDM) during pregnancy is uncertain. AIM The objectives of this study were to assess the associations between UACR (performed at the time of GDM diagnosis) and various maternal parameters and to evaluate its correlation with pregnancy outcomes. MATERIALS AND METHODS We conducted a retrospective review of women with GDM who attended antenatal clinics at a single centre between March 2010 and September 2013. RESULTS Among 1015 women included in this study, high UACR levels were associated with advancing maternal age, maternal obesity, gestational hypertension, elevated glycosylated haemoglobin (HbA1c) and high fasting glucose level. After adjustments for various maternal factors, only advancing age, HbA1c and fasting glucose level were associated with UACR. In terms of pregnancy outcomes, elevated UACR was not associated with adverse events, but was a predictor for pre-eclampsia. CONCLUSIONS The finding that UACR was associated with glycaemic status in women with GDM suggests early micro-vascular disease may be present in women who had greater degree of hyperglycaemia. This raises the question of whether women with GDM and elevated UACR may be at higher risk of developing cardiovascular disease in the future. Long-term follow-up of this subgroup of women would be worthwhile.

Abstract
Two patients with type 2 DM developed acute kidney injury and lactic acidosis following colonoscopy despite withholding metformin. We recommend that DM patients on metformin also withhold ACEI, ARB until their dehydration is reversed after colonoscopy. This should reduce the risk of acute renal failure (ARF) and of lactic acidosis.

Abstract
It is unclear how current guidelines suggesting bariatric surgery as a therapeutic option for management of obesity complicated by type 2 diabetes mellitus are utilised in clinical practice. Of 609 patients with T2DM assessed in this study, 147 had a BMI ≥ 35 kg/m2; and of these 147, patients where bariatric surgery had been discussed as compared to those where it had not been discussed, had a higher BMI (44.4 ± 6.8 kg/m2 versus 40.3 ± 5.2 kg/m2, p < 0.005). Diabetes related factors did not differ between the two groups.

Abstract
AIM This study was designed to document the factors influencing therapeutic decisions in the management of diabetes in relation to stage of medical career. METHODS An anonymous survey was distributed among medical students, resident medical officers (RMOs) and general practitioners (GPs) presenting a hypothetical case of a 58 year old patient with sub-optimally controlled diabetes on metfomin and gliclazide. Participants were then asked for their next step in management and about factors that would influence their decision-making. RESULTS GPs (n=72) were most likely to add pioglitazone (33.3%). RMOs (n=42) were more likely to add insulin (47.6%, p<0.01 vs. GPs). Medical students (n=40) were more likely to review diet and observe (42.5%, p<0.01 vs. GPs). Significant differences were observed between the 3 groups in what influenced their choice of therapy. GPs were most likely to take into account patient related factors such as patient's motivation to improve glycaemic control. CONCLUSION GPs were less likely to initiate insulin therapy, and our results suggest that this may be due to their greater awareness of patient related barriers to commencing insulin. These results justify support for continuing medical education of GPs that focuses on evidence based guidelines.

Abstract
BACKGROUND AND OBJECTIVE Hyperglycaemia during hospital admission is associated with poor outcomes in patients admitted with acute myocardial infarction, stroke and pneumonia. Less evidence exists for effect of diabetes mellitus (DM) on those admitted with an acute exacerbation of COPD (AECOPD). We proposed that comorbidity with DM is associated with an increased length of stay in patients admitted with AECOPD. METHODS Records of patients admitted with AECOPD during 2007 were reviewed. Data on the presence of diagnosed DM, length of stay and markers of disease severity and other comorbidities were collected. Analysis was performed using generalized estimating equations to adjust for correlation between multiple admissions in some individuals. Log-transformed length of stay and death were the dependent variables. RESULTS There were 246 admissions in 172 subjects. Diabetes was a comorbid condition in 22% of admissions for AECOPD. There was a trend for increased length of stay and deaths in those with diabetes (geometric mean 7.8 days and 8% mortality respectively) compared with those without diabetes (6.5 days and 4%). However, after adjustment for covariates, the differences were not statistically significant. CONCLUSIONS Taken together with a previous study that revealed a similar trend, our study suggests that comorbid DM prolongs length of stay and increases risk of death in patients with AECOPD. Further studies are now required to elucidate the reasons for these poorer outcomes, in particular whether premorbid glycaemic control or inpatient control is responsible, as these are potentially modifiable factors.

Abstract
AIMS To establish the incidence of post-transplant diabetes mellitus (PTDM) and factors predictive of its development. METHODS This was a retrospective review (using hospital records and transplant database) of 97 consecutive adult patients who underwent cardiac transplantation at St Vincent's Hospital, Sydney, Australia. RESULTS Mean follow-up was 27 months. Excluding five patients who had pre-existing diabetes, the cumulative incidence of PTDM was 15.7%. Pre-transplant random blood glucose (5.6 +/- 0.8 vs. 5.2 +/- 0.6 mmol/l, P<0.05), family history (46% vs. 15%, P<0.05) and a continuing requirement for insulin on the second post-transplant day (54% vs. 15%, P< 0.01) differed in those who developed PTDM as opposed to those who remained free of diabetes. Patients who developed PTDM had received slightly higher mean doses of prednisolone at three months (0.21 +/- 0.03 vs. 0.19 +/- 0.03 mg. kg(-1)/day(-1), P<0.01). Of the factors identifiable prior to initial hospital discharge, only family history of diabetes mellitus and second post-transplant day insulin requirement independently predicted the occurrence of PTDM. CONCLUSIONS A family history of diabetes and the need for insulin beyond the first 24 h after transplantation are factors identifiable prior to hospital discharge, which predict patients at risk of developing PTDM. In such patients, consideration to minimizing the dose of glucocorticoids should be given where possible.

Abstract
The neuropeptide galanin mediates its activities through G-protein-coupled receptors, and three receptor subtypes have been described with distinctly different patterns of regional tissue expression. GALR1 is predominantly expressed in basal forebrain, hypothalamus, as well as spinal cord. GALR2 has a wider distribution in brain and is also present in the pituitary gland and peripheral tissues. GALR3 has been found to be widely distributed at low abundance. We examined the distribution of GALR2 in rat brain and pituitary by in situ hybridization histochemistry and found it abundant in regions of hippocampus, piriform and entorhinal cortex, basal nucleus of the accessory olfactory tract, amygdala, hypothalamic nuclei, Purkinje cells, and discrete brainstem nuclei. It is also highly expressed in the intermediate and anterior lobes of the pituitary. Using combined in situ hybridization immunohistochemistry we characterized the neurotransmitter and hormonal phenotype of cells expressing GALR2 mRNA in the hypothalamus and pituitary gland. Our findings suggest GALR2 is a receptor mediating important functions of galanin in the hypothalamic-pituitary axis and may also play a role in hippocampal and cerebellar function.

Abstract
Two patients received total parenteral nutrition (TPN) to manage irreversible bowel obstruction secondary to gynecological malignancy. The use of TPN prolonged their lives considerably, but also led to complications, both from the TPN and from the natural progression of the cancers. Although TPN is increasingly considered as a possible treatment for selected patients with malignant bowel obstruction who are not suitable for surgery, the literature regarding this practice is conflicting. It should be considered only in those patients with good performance status, and then after careful attention to not only the likely medical and symptomatic outcomes, but also the ethical implications of such a management strategy.

Abstract
Hepatitis C has recently been recognized as a secondary cause of osteosclerosis; a further example, the first outside of North America, is described. A 37-year-old man with a history of intravenous drug use and known to be hepatitis C antibody positive presented with bone pain. Radiographs and magnetic resonance imaging demonstrated an increase in cortical and trabecular bone that on biopsy was of a normal lamellar pattern but markedly sclerotic. Biochemical markers of bone formation (serum osteocalcin) and resorption (urinary hydroxyproline excretion rate) were both markedly elevated. Pain lessened following administration of pamidronate. Biochemical markers of bone turnover fell towards their reference ranges 12 months after initiating pamidronate therapy but without significant change in bone mineral density. Osteosclerosis is a rare complication of hepatitis C infection, the symptoms of which are controllable with diphosphonate therapy.
