INTRODUCTION
We previously reported predictors of mortality in 1786 adults with diabetes or stress hyperglycemia (glucose>180 mg/dL twice in 24 hours) admitted with COVID-19 from March 2020 to February 2021 to five university hospitals. Here, we examine predictors of readmission.
RESEARCH DESIGN AND METHODS
Data were collected locally through retrospective reviews of electronic medical records from 1786 adults with diabetes or stress hyperglycemia who had a hemoglobin A1c (HbA1c) test on initial admission with COVID-19 infection or within 3 months prior to initial admission. Data were entered into a Research Electronic Data Capture (REDCap) web-based repository, and de-identified. Descriptive data are shown as mean±SD, per cent (%) or median (IQR). Student's t-test was used for comparing continuous variables with normal distribution and Mann-Whitney U test was used for data not normally distributed. X test was used for categorical variable.
RESULTS
Of 1502 patients who were alive after initial hospitalization, 19.4% were readmitted; 90.3% within 30 days (median (IQR) 4 (0-14) days). Older age, lower estimated glomerular filtration rate (eGFR), comorbidities, intensive care unit (ICU) admission, mechanical ventilation, diabetic ketoacidosis (DKA), and longer length of stay (LOS) during the initial hospitalization were associated with readmission. Higher HbA1c, glycemic gap, or body mass index (BMI) were not associated with readmission. Mortality during readmission was 8.0% (n=23). Those who died were older than those who survived (74.9±9.5 vs 65.2±14.4 years, p=0.002) and more likely had DKA during the first hospitalization (p<0.001). Shorter LOS during the initial admission was associated with ICU stay during readmission, suggesting that a subset of patients may have been initially discharged prematurely.
CONCLUSIONS
Understanding predictors of readmission after initial hospitalization for COVID-19, including older age, lower eGFR, comorbidities, ICU admission, mechanical ventilation, statin use and DKA but not HbA1c, glycemic gap or BMI, can help guide treatment approaches and future research in adults with diabetes.

BACKGROUND
There is a growing consensus that fasting-induced ketosis has beneficial effects on human physiology. Despite these compelling benefits, fasting-induced ketosis raises concerns in some clinicians because it is often inappropriately compared with the pathologic uncontrolled ketone production in diabetic ketoacidosis. The determinants of the inter-individual differences in the intensity of ketosis during long-term fasting is unknown.
METHODS
We monitored daily variations in fasting ketonemia, as well as ketonuria, which is less invasive, in a large cohort of 1610 subjects, fasting between 4 and 21 days with the Buchinger Wilhelmi program, minimally supplemented with ~75-250 kcal (daily fruit juice, vegetable soup, and honey).
RESULTS
Ketonuria was detected in more than 95% of fasting subjects from day 4 onwards. Subjects consuming only soups, without fruit juice or honey, exhibited reduced caloric intake (72 kcal instead of 236 kcal) and carbohydrate intake (15.6 g instead of 56.5 g), leading to more intense ketonuria. Participants with high ketonuria were, in the majority, males, young, had a higher body weight, and had lower HDL-C and urea values. They had a larger decrease in blood glucose, glycated haemoglobin levels, body weight, and waist circumference. Furthermore, in the high-ketonuria group, a larger increase in blood uric acid concentration was observed.
CONCLUSION
Our study showed that long-term fasting triggered ketosis, never reaching pathological levels, and that ketosis is influenced by age, gender, health, and the level of physical activity. Furthermore, it is modulated but not suppressed by minimal carbohydrate intake. Our study paves the way for better understanding how supplementation can modulate the therapeutic effects and tolerability of long-term fasting.

OBJECTIVE
Type 1 diabetes (T1D) screening programmes testing islet autoantibodies (IAbs) in childhood can reduce life-threatening diabetic ketoacidosis. General population screening is required to detect the majority of children with T1D, since in >85% there is no family history. Age 3-5 years has been proposed as an optimal age for a single screen approach.
DESIGN
Capillary samples were collected from children attending their preschool vaccination and analysed for IAbs to insulin, glutamic acid decarboxylase, islet antigen-2 and zinc transporter 8 using radiobinding/luciferase immunoprecipitation system assays. Acceptability was assessed using semistructured interviews and open-ended postcard questionnaires with parents.
SETTING
Two primary care practices in Oxfordshire, UK.
MAIN OUTCOME MEASURES
The ability to collect capillary blood to test IAbs in children at the routine preschool vaccination (3.5-4 years).
RESULTS
Of 134 parents invited, 66 (49%) were recruited (median age 3.5 years (IQR 3.4-3.6), 26 (39.4%) male); 63 provided a sample (97% successfully), and one participant was identified with a single positive IAb. Parents (n=15 interviews, n=29 postcards) were uniformly positive about screening aligned to vaccination and stated they would have been less likely to take part had screening been a separate visit. Themes identified included preparedness for T1D and the long-term benefit outweighing short-term upset. The perceived volume of the capillary sample was a potential concern and needs optimising.
CONCLUSIONS
Capillary IAb testing is a possible method to screen children for T1D. Aligning collection to the preschool vaccination visit can be convenient for families without the need for an additional visit.

Ischemic myocardial injury in a diabetes mellitus (DM) patient can be a trigger or a complication of diabetic ketoacidosis (DKA). This case series examines the phenomenon of elevated troponin levels in patients with DKA in the absence of obstructive coronary artery disease. Two out of three cases showed ST-segment elevation on electrocardiogram (EKG). Despite the absence of obstructive coronary artery disease on coronary angiography, all cases exhibited troponinemia (>79 ng/dl). These elevated troponin levels and EKG changes may pose diagnostic challenges for clinicians. Alternatively, troponinemia could be due to myocardial injury caused by acidotic stress and free fatty acid utilization along with increased myocardial oxygen demand and not obstructive coronary artery pathology in every case. However, a better understanding of the complex interplay between DKA and myocardial injury needs further research.

Hamman's syndrome or Macklin phenomenon - spontaneous pneumomediastinum - is an uncommon condition that often gets missed due to the lack of awareness. It may rarely be associated with diabetic ketoacidosis (DKA) due to repeated vomiting or Kussmaul breathing associated with it. This condition is self-resolving, and improvement in symptoms is usually observed with appropriate management of DKA. Secondary pneumomediastinum is relatively more common, but spontaneous pneumomediastinum, which is rare, is often diagnosed incidentally. Here, we describe a case of a 24-year-old gentleman where this condition was found incidentally during the examination and was confirmed through imaging (X-ray and CT scans) and resolved with successful management of DKA.

Background Some studies suggest that the SARS-CoV-2 pandemic has contributed to diverting attention from other community-acquired infections (CAIs), leading to an increase in their incidence and severity. Our study aimed to describe and compare clinical features of CAI before and during the pandemic as a factor precipitating diabetes ketoacidosis (DKA). Methodology We included 250 patients who presented with DKA due to CAIs, other than SARS-CoV-2, divided into two distinct groups: 100 patients (G1) who consulted two years before the pandemic, and 150 patients (G2) who consulted during the SARS-CoV-2 pandemic. Cases in both groups were matched for age and type and duration of diabetes. Primary outcomes were a longer diagnosis delay and more severe DKA in G2 during the pandemic. Secondary outcomes included blood test results, duration of ketosis, duration of antibiotic therapy, and diabetes treatment. Results The diagnosis and treatment delays were longer for patients seeking medical care during the pandemic (p < 0.001). The duration of DKA was also significantly longer in the G2 group (p = 0.007). During the pandemic, patients' blood tests showed more anomalies with higher glycated hemoglobin (p = 0.02), C-reactive protein (p = 0.001), and lymphocytosis (p = 0.016). The duration of antibiotic therapy was also significantly longer in G2 (p = 0.01). Conclusions This study showed the impact of the COVID-19 pandemic on the management of diseases other than SARS-CoV-2. Indeed, several factors played a part in the increased incidence of CAIs, which were more severe than in the pre-pandemic period. These included fear of contagion, confinement, and physicians' preoccupation with the pandemic.

Destructive thyroiditis and secondary adrenal insufficiency are major endocrinological immune-related adverse events of immune checkpoint inhibitors (ICIs). However, the timing at which each event occurs most frequently after drug administration varies, and cases where multiple events occur simultaneously are rare. We encountered a patient who concurrently suffered from thyrotoxicosis and adrenal insufficiency. An 80-year-old woman with a history of type 2 diabetes mellitus (DM) was diagnosed with stage IVA squamous cell carcinoma of the lungs. Treatment with a combination of nivolumab and ipilimumab was initiated. Although she tested positive for thyroglobulin antibody and transient subclinical hyperthyroidism was observed after two courses, treatment with ICIs was continued. Four months later, treatment was discontinued due to drug-induced lung disease. One month after the last administration, the patient became unconscious and was admitted to another hospital, diagnosed with diabetic ketoacidosis, urinary tract infection, and sepsis. After acute-phase treatment, she was transferred to our hospital due to persistent fever and tachycardia. Thyrotoxicosis and adrenal insufficiency were observed, with high levels of free thyroxine, low thyroid-stimulating hormone (TSH), and cortisol levels. Treatment with extracellular fluids, potassium iodide, beta-blockers, and hydrocortisone was initiated, and the patient's condition improved. No other pituitary hormone deficiencies were observed. She was diagnosed with painless thyroiditis and secondary adrenal insufficiency based on the positive thyroglobulin antibody, negative TSH receptor antibody, decreased Doppler flow in thyroid ultrasonography, low adrenocorticotrophic hormone (ACTH), and low response of ACTH and cortisol to corticotropin-releasing hormone loading test. MRI revealed no abnormalities. We report a case of thyrotoxicosis and secondary adrenal insufficiency five months after the first administration of nivolumab and ipilimumab. Careful follow-up and early detection of endocrine disorders are critical in patients treated with a combination of ICIs.

Type 1 diabetes mellitus (T1DM) is a metabolic disorder characterized by an absolute deficiency of insulin due to pancreatic failure. Diabetes ketoacidosis (DKA) has emerged as one of the most common complications of T1DM. Although exceedingly rare, the onset of T1DM with DKA may result in lipemia secondary to severe hypertriglyceridemia (HTG), accounting for several cases in the pediatric population. Along this line, plasma exchange treatment in children with DKA and severe hyperlipidemia has only been reported in some cases. In this case report, the diagnosis of an 11-year-old girl with diabetes ketoacidosis accompanied by severe HTG, along with subsequent plasma exchange treatment, is presented. Initially, the patient received initial management with crystalloid fluid bolus and intravenous insulin therapy. Despite rapid correction of acidosis, persistent HTG subsequently prompted the plasma exchange treatment. A total of three sessions were administered over 2 days, leading to a significant reduction in the triglyceride levels and corneal opacity resolution, indicating a successful therapeutic intervention.

The COVID-19 pandemic with the outbreak of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has been one of the largest topics of discussion in the medical world over the last few years. Most of the research has focused on the risks and correlation of chronic diseases and immunosuppression with the severity and mortality of the viral infection. Less research has occurred in the setting of post-infectious sequelae and the long-term effects of COVID-19 with the development of chronic conditions and diseases, such as new-onset type 1 diabetes mellitus. The incidence of diabetic ketoacidosis (DKA) has increased during the COVID-19 pandemic, but the relationship between the two conditions remains to be fully understood. We report the case of a 24-year-old male who presents with malaise, polyuria, polydipsia, headache, and fatigue and was eventually found to be in diabetic ketoacidosis (DKA). He had a history of COVID-19 infection 12 weeks prior to this presentation. He also had a family history of DKA and type 1 diabetes mellitus. This case highlights the need to perform an in-depth workup for each patient with DKA and new-onset diabetes mellitus in order to find a potential cause of the autoimmune condition.

In patients with diabetes, diabetic ketoacidosis (DKA) is a well-documented potential complication, usually presenting with hyperglycemia, anion gap acidosis, and positive ketones. Metformin toxicity in the setting of acute renal failure is also a well-known cause of lactic acidosis. However, metformin-induced euglycemic ketoacidosis is less well-known or studied. We report a case of metformin toxicity in the setting of acute renal failure with both lactic acidosis and ketosis and an initial confounded clinical presentation of sulphonylurea-induced hypoglycemia. A high index of suspicion for metformin-associated lactic acidosis (MALA) and metformin-associated lactic acidosis with euglycemic ketoacidosis (MALKA) should be in place in patients who are taking metformin and presenting with acute renal failure and euglycemia.
