Meta-Analysis Review
Type 1 diabetes mellitus (T1DM) is a major subtype of diabetes and is usually diagnosed at a young age with insulin deficiency. The life expectancy of T1DM patients has increased substantially in comparison with that three decades ago due to the availability of exogenous insulin, though it is still shorter than that of healthy people. However, the relation remains unclear between T1DM and dementia as an aging-related disease. We conducted a systematic review of existing literature on T1DM and cognition impairments by carrying out searches in electronic databases Medline, EMBASE, and Google Scholar. We restricted our review to studies involving only human subjects and excluded studies on type 2 diabetes mellitus or non-classified diabetes. A meta-analysis was first performed on the relationship between T1DM and cognitive changes in youths and adults respectively. Then the review focused on the cognitive complications of T1DM and their relation with the characteristics of T1DM, glycemic control, diabetic complications, comorbidities, and others. First, age at onset, disease duration, and glycemic dysregulation were delineated for their association with cognitive changes. Then diabetic ketoacidosis, angiopathy, and neuropathy were examined as diabetic complications for their involvement in cognitive impairments. Lastly, body mass index and blood pressure were discussed for their relations with the cognitive changes. Future studies are needed to elucidate the pathogenesis of T1DM-related cognitive impairments or dementia.

Review
STUDY OBJECTIVE
Currently only minimal information is available regarding risk factors for the development of sodium glucose cotransporter-2 inhibitor (SGLT2i)-related diabetic ketoacidosis (DKA). We aim to identify individual patient characteristics associated with cases of SGLT2i-related DKA to better describe potential risk factors.
DESIGN
Systematic review of primary literature.
PATIENTS
Thirty-four case reports of patients with type 1 and type 2 diabetes mellitus who developed DKA while receiving an SGLT2i.
METHODS AND MAIN RESULTS
This systematic review investigated the relationship between SGLT2i and DKA in patients with diabetes. The existing literature was reviewed with a primary outcome to identify patient-specific factors contributing to the incidence of ketoacidosis in patients with diabetes who were treated with a SGLT2i. Numerous databases were searched to identify appropriate primary literature. Search terms included canagliflozin, dapagliflozin, empagliflozin, SGLT2, sodium glucose cotransporter-2 inhibitor, diabetic ketoacidosis, ketoacidosis, metabolic acidosis, and acidosis. Primary literature was analyzed via descriptive statistics. Thirty-four individual case reports were identified via the primary literature search. Two-thirds (25 cases) involved patients with a diagnosis of type 2 diabetes mellitus (T2DM). The average blood glucose on presentation for SGLT2i-induced DKA was 265.6 ± 140.7 mg/dl (14.7 ± 7.8 mmol/L), with common symptoms including nausea, vomiting, and abdominal pain. Common precipitating factors included patients who were diagnosed with T2DM and were subsequently found to have latent autoimmune diabetes of adulthood, patients who had recently undergone major surgery, or patients who had decreased or discontinued insulin. No cases were fatal.
CONCLUSION
In this review, episodes of DKA with SGLT2i use were characterized by lower blood glucose levels and were often caused by a precipitating factor. Understanding precipitating factors for SGLT2i-related DKA may help providers better identify patients at risk for development of DKA.

Meta-Analysis Review
Viral infections may increase the risk of developing type 1 diabetes (T1D), and recent reports suggest that Coronavirus Disease 2019 (COVID-19) might have increased the incidence of pediatric T1D and/or diabetic ketoacidosis (DKA). Therefore, this meta-analysis aims to estimate the risk of global pediatric new-onset T1D, DKA, and severe DKA before and after the COVID-19 pandemic. A systematic search of MEDLINE/PubMed, CINAHL, Scopus, and EMBASE was conducted for articles published up to March 2022. A random-effects meta-analysis was performed to compare the relative risk of T1D and DKA among pediatric patients with T1D between the COVID-19 pre-pandemic and pandemic periods. We also compared glucose and HbA1c values in children who were newly diagnosed with T1D before and after the COVID-19 pandemic. The global incidence rate of T1D in the 2019 period was 19.73 per 100 000 children and 32.39 per 100 000 in the 2020 period. Compared with pre-COVID-19 pandemic, the number of worldwide pediatric new-onset T1D, DKA, and severe DKA during the first year of the COVID-19 pandemic increased by 9.5%, 25%, and 19.5%, respectively. Compared with pre-COVID-19 pandemic levels, the median glucose, and HbA1c values in newly diagnosed T1D children after the COVID-19 pandemic increased by 6.43% and 6.42%, respectively. The COVID-19 pandemic has significantly increased the risk of global pediatric new-onset T1D, DKA, and severe DKA. Moreover, higher glucose and HbA1c values in newly diagnosed T1D children after the COVID-19 pandemic mandates targeted measures to raise public and physician awareness.

BACKGROUND
Sodium-glucose cotransporter-2 inhibitors (SGLT2 inhibitors) rarely cause euglycemic diabetic ketoacidosis (euDKA) in diabetic patients. The aim was to identify demographic, clinical, and predisposing factors for euDKA from published case reports.
METHODS
A systematic review of published case reports of euDKA in patients receiving SGLT2 inhibitors and meta-analysis of clinical trials to quantify the risk ratio (RR) of DKA in patients receiving SGLT2 inhibitors. PubMed and EMBASE databases were searched for the case reports of and clinical trials from January 2010 to August 2020. Studies published in English language were included and other languages were excluded. Data related to patients' demography, clinical presentation, drug and dose of SGLT2 inhibitors, and concomitant medication were extracted. Incidence of diabetic ketoacidosis (DKA) extracted from clinical trials. Data related to demographic, clinical, and other parameters presented as ratios and proportions and incidence of DKA in RR using Review Manager 5.3.
RESULTS
Forty-seven of 160 reports with an aggregate of 77 patients were included in the analysis. The majority of the patients were females (67.53%), with T2DM and with gastrointestinal symptoms (58%). Surgery was the most common precipitating factor (/ = 15/77). Canagliflozin (/ = 34/77) was the commonest SGLT2 inhibitor reported along with metformin as the concomitant medication (63.6%). The pooled RR of DKA was 3.70 (95%CI 2.58, 5.29) and I = 0%.
CONCLUSION
euDKA is commonly seen in middle-aged female, T2DM patients taking SGLT2 inhibitors along with metformin. The risk of DKA in patients receiving SGLT2 inhibitors increases by 3.7 times than the other medication.

Meta-Analysis
IMPORTANCE
Diabetic ketoacidosis (DKA) is a serious complication of type 1 diabetes mellitus, which may lead to significant morbidity and mortality.
OBJECTIVES
To compare the safety and efficacy of liberalised versus conservative intravenous fluid regimens in the management of DKA in children.
DATA SOURCE AND STUDY SELECTION
Databases from inception to January 2022: MEDLINE, EMBASE, CINAHL and the Cochrane Central Register of Controlled Trials were included. Only randomised controlled trials (RCTs) that included children aged under 18 years were assessed. Two reviewers performed data assessment and extraction.
DATA EXTRACTION AND SYNTHESIS
Three studies out of 1536 citations were included.
MAIN OUTCOMES
The time to the recovery from the DKA; the frequency of paeditric intensive care unit (PICU) admissions; development of brain oedema; reduction in Glasgow Coma Scale (GCS); development of acute kidney injury and all-cause mortality.
RESULTS
We included three RCTs (n=1457). No evidence of difference was noted in the GCS reduction (risk ratio (RR)=0.77, 95% CI 0.44 to 1.36) or development of brain oedema (RR=0.50, 95% CI 0.15 to 1.68). The time to recovery from DKA was longer in the conservative group (mean difference=1.42, 95% CI 0.28 to 2.56). Time to hospital discharge, adverse or serious adverse events were comparable in the two studied groups.
CONCLUSION
There is no evidence from this meta-analysis that rate of fluid administration has any effect on adverse neurological and other outcomes or length of hospital stay.

Review
OBJECTIVES
To summarise incidence and prevalence of diabetic ketoacidosis (DKA) in adults with type 1 diabetes (T1D) for the overall patient population and different subgroups (age, sex, geographical region, ethnicity and type of insulin administration).
DESIGN
Systematic literature review (SLR).
DATA SOURCES
Medline (via PubMed) and Embase (1 January 2000 to 23 June 2016).
STUDY SELECTION
Peer-reviewed observational studies with reported data on the incidence or prevalence of DKA in T1D adults were included. A single reviewer completed the study screening and selection process and a second reviewer performed an additional screening of approximately 20% of the publications; two reviewers independently conducted the quality assessment; the results were narratively synthesised.
RESULTS
Out of 1082 articles, 19 met the inclusion and exclusion criteria, with two additional studies identified that did not specify the patient age range and are therefore not included in the SLR. Overall, eight studies reported incidence with a range of 0-56 per 1000 person-years (PYs), with one outlying study reporting an incidence of 263 per 1000 PYs. Eleven studies reported prevalence with a range of 0-128 per 1000 people. Prevalence of DKA decreased with increasing age. Subgroup analyses were performed using data from no more than two studies per subgroup. There was a higher prevalence of DKA reported in women, non-whites and patients treated with insulin injections compared with men, whites and patients using continuous subcutaneous insulin infusion pumps, respectively.
CONCLUSIONS
To our knowledge, this is the first SLR on the epidemiology of DKA in T1D adults. Despite an increasing prevalence of T1D in recent years, DKA in adults has been poorly characterised. In an era when the benefit-risk profiles of new antidiabetic therapies are being evaluated, including the potential risk of DKA, there is a clear need to better elucidate the expected rate of DKA among T1D adults.

BACKGROUND
The etiology of acute metabolic acidosis (aMA) is heterogeneous, and the consequences are potentially life-threatening. The aim of this article was to summarize the causes and management of aMA from a clinician's perspective.
SUMMARY
We performed a systematic search on PubMed, applying the following search terms: "acute metabolic acidosis," "lactic acidosis," "metformin" AND "acidosis," "unbalanced solutions" AND "acidosis," "bicarbonate" AND "acidosis" AND "outcome," "acute metabolic acidosis" AND "management," and "acute metabolic acidosis" AND "renal replacement therapy (RRT)/dialysis." The literature search did not consider diabetic ketoacidosis at all. Lactic acidosis evolves from various conditions, either with or without systemic hypoxia. The incidence of metformin-associated aMA is actually quite low. Unbalanced electrolyte preparations can induce hyperchloremic aMA. The latter potentially worsens kidney-related outcome parameters. Nevertheless, prospective and controlled data are missing at the moment. Recently, bicarbonate has been shown to improve clinically relevant endpoints in the critically ill, even if higher pH values (>7.3) are targeted. New therapeutics for aMA control are under development, since bicarbonate treatment can induce serious side effects. Key Messages: aMA is a frequent and potentially life-threatening complication of various conditions. Lactic acidosis might occur even in the absence of systemic hypoxia. The incidence of metformin-associated aMA is comparably low. Unbalanced electrolyte solutions induce hyperchloremic aMA, which most likely worsens the renal prognosis of critically ill patients. Bicarbonate, although potentially deleterious due to increased carbon dioxide production with subsequent intracellular acidosis, improves kidney-related endpoints in the critically ill.

Meta-Analysis Review
BACKGROUND
Mucormycosis, a rare fungal infection, has shown an increase in the number of reported cases during the COVID-19 pandemic.
OBJECTIVES
To provide a comprehensive insight into the characteristics of COVID-19-associated mucormycosis, through a systematic review and meta-analysis.
METHODS OF DATA SYNTHESIS
Demographic information and clinical features were documented for each patient. Logistic regression analysis was used to predict the risk of mortality.
DATA SOURCES
PubMed, Scopus, Web of Science, Cochrane, CINAHL, Ovid MEDLINE, and FungiSCOPE.
STUDY ELIGIBILITY CRITERIA
Studies reporting individual-level information in patients with adult COVID-19-associated mucormycosis (CAM) between 1 January 2020 and 28 December 2022.
PARTICIPANTS
Adults who developed mucormycosis during or after COVID-19.
INTERVENTIONS
Patients with and without individual clinical variables were compared.
ASSESSMENT OF RISK OF BIAS
Quality assessment was performed based on the National Institutes of Health quality assessment tool for case series studies.
RESULTS
Nine hundred fifty-eight individual cases reported from 45 countries were eligible. 88.1% (844/958) were reported from low- or middle-income countries. Corticosteroid use for COVID-19 (78.5%, 619/789) and diabetes (77.9%, 738/948) were common. Diabetic ketoacidosis (p < 0.001), history of malignancy (p < 0.001), underlying pulmonary (p 0.017), or renal disease (p < 0.001), obesity (p < 0.001), hypertension (p 0.040), age (>65 years) (p 0.001), Aspergillus coinfection (p 0.037), and tocilizumab use during COVID-19 (p 0.018) increased the mortality. CAM occurred on an average of 22 days after COVID-19 and 8 days after hospitalization. Diagnosis of mucormycosis in patients with Aspergillus coinfection and pulmonary mucormycosis was made on average 15.4 days (range, 0-35 days) and 14.0 days (range, 0-53 days) after hospitalization, respectively. Cutaneous mucormycosis accounted for <1% of the cases. The overall mortality rate was 38.9% (303/780).
CONCLUSION
Mortality of CAM was high, and most reports were from low- or middle-income countries. We detected novel risk factors for CAM, such as older age, specific comorbidities, Aspergillus coinfection, and tocilizumab use, in addition to the previously identified factors.

Critical Care Explorations Jan 2022This systematic review and meta-analysis compared the use of saline to balanced crystalloid for fluid resuscitation in patients with diabetic ketoacidosis (DKA). (Review)
Review
OBJECTIVES
This systematic review and meta-analysis compared the use of saline to balanced crystalloid for fluid resuscitation in patients with diabetic ketoacidosis (DKA).
DATA SOURCES
We searched databases including Medline, Embase, and the Cochrane registry.
STUDY SELECTION
We included randomized controlled trials (RCTs) that compared saline to balanced crystalloid in patients with DKA.
DATA EXTRACTION
We pooled estimates of effect using relative risk for dichotomous outcomes and mean differences (MDs) for continuous outcomes, both with 95% CIs. We assessed risk of bias for included RCTs using the modified Cochrane tool and certainty of evidence using Grading of Recommendations, Assessment, Development, and Evaluation methodology.
DATA SYNTHESIS
We included eight RCTs ( = 482 patients). Both time to DKA resolution (MD, 3.51 hr longer; 95% CI, 0.90 longer to 6.12 longer; moderate certainty) and length of hospital stay (MD, 0.89 d longer in saline group; 95% CI, 0.34 longer to 1.43 d longer; moderate certainty) are probably longer in the saline group compared with the balanced crystalloid group, although for the latter, the absolute difference (under 1 d) is small. Post-resuscitation serum chloride level may be higher (MD, 1.62 mmol/L higher; 95% CI, 0.40 lower to 3.64 higher; low certainty), and post-resuscitation serum bicarbonate is probably lower (MD, 1.50 mmol/L; 95% CI, 2.33 lower to 0.67 lower; moderate certainty) in those receiving saline.
CONCLUSIONS
In patients with DKA, the use of saline may be associated with longer time to DKA resolution, higher post-resuscitation serum chloride levels, lower post-resuscitation serum bicarbonate levels, and longer hospital stay compared with balanced crystalloids. Pending further data, low to moderate certainty data support using balanced crystalloid over saline for fluid resuscitation in patients with DKA.

Meta-Analysis Review
BACKGROUND
Current guidelines suggest the use of isotonic saline (IS) infusion as the preferred resuscitation fluid in the management of diabetic ketoacidosis (DKA). However, balanced electrolyte solutions (BES) have been proposed as an alternative due to a lower propensity to cause hyperchloremic metabolic acidosis. Evidence regarding the use of BES in DKA remains limited.
OBJECTIVES
To determine if the use of BES in fluid resuscitation leads to faster resolution of DKA compared to IS.
METHODS
The study involves a comprehensive search of literature from PubMed, Cochrane CENTRAL, Google Scholar, and Science Direct of clinical trials addressing the use of BES vs IS in fluid resuscitation in DKA. The time to resolution of DKA was examined as the primary endpoint. Pooled hazard ratios (HR) and Mean Difference (MD) in hours with their 95% confidence intervals (CI) were calculated using a random-effects model.
RESULTS
The literature search included 464 studies that were screened individually. A total of 9 studies were identified but 6 studies were excluded due to irrelevance in the outcome of interest and target population. The pooled hazard ratio HR significantly revealed 1.46 [1.10 to 1.94] (p = 0.009) with 12% heterogeneity while MD was -3.02 (95% CI -6.78-0.74; p = 0.12) with heterogeneity of 85%.
CONCLUSION
Considering the evidence from pooled small randomized trials with moderate overall certainty of evidence, the use of BES in DKA was associated with faster rates of DKA resolution compared to IS.
