Meta-Analysis
QUESTION
Effective prevention of suicide requires a comprehensive understanding of risk factors.
STUDY SELECTION AND ANALYSIS
Five databases were systematically searched to identify psychological autopsy studies (published up to February 2022) that reported on risk factors for suicide mortality among adults in the general population. Effect sizes were pooled as odds ratios (ORs) using random-effects models for each risk factor examined in at least three independent samples.
FINDINGS
A total of 37 case-control studies from 23 countries were included, providing data on 40 risk factors in 5633 cases and 7101 controls. The magnitude of effect sizes varied substantially both between and within risk factor domains. Clinical factors had the strongest associations with suicide, including any mental disorder (OR=13.1, 95% CI 9.9 to 17.4) and a history of self-harm (OR=10.1, 95% CI 6.6 to 15.6). By comparison, effect sizes were smaller for other domains relating to sociodemographic status, family history, and adverse life events (OR range 2-5).
CONCLUSIONS
A wide range of predisposing and precipitating factors are associated with suicide among adults in the general population, but with clear differences in their relative strength.

Myxedema may be the first presentation of patients with undiagnosed hypothyroidism. Definitive management is with thyroid hormone but supportive measures, identification and treatment of precipitating factors in an appropriately safe environment are vital. There is no consensus about preferred thyroid hormone regimen. Corticosteroid therapy is given until adrenal insufficiency has been excluded. We present here a case of seventy-four years old woman of myxodema coma.

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.

Review
Pemphigus is a life-threatening autoimmune blistering disease affecting skin and mucous membranes. Despite its etiopathogenesis remains largely unknown, several trigger and predisposing factors have been reported. Pemphigus is caused by autoantibodies that target desmoglein 1 and desmoglein 3, impacting desmosome function. However, circulating autoantibodies are often the consequence of a precipitating factor that occurs in predisposed individuals. This review aims to describe and discuss almost all trigger and predisposing factors reported as possible or probable cause of the disease. Among the reported trigger factors that may induce or exacerbate pemphigus, we have found of particular interest: drug intake (especially thiol- and phenol-containing compounds), vaccines, infections, as well as some reports about pregnancy, radiations, emotional stress, pesticides and physical trauma. Moreover, we discuss the possible role of food intake in pemphigus onset and particular attention is given to dietary factors containing thiol, phenol and tannin compounds. A trigger factor is "the straw that breaks the camel's back," and often acts together with predisposing factors. Here we discuss how pemphigus onset may be influenced by genetic susceptibility and comorbidities like thyroid diseases, malignancies and other autoimmune disorders. To identify other hitherto unknown trigger and predisposing factors, well designed prospective studies are needed. In this context, future research should explore their connection with the aim to advance our understanding of pemphigus pathogenesis.

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.

Review
This review summarizes current knowledge concerning incidence, risk factors, and mechanisms of perioperative nerve injury, with focus on local anesthetic-induced neurotoxicity. Perioperative nerve injury is a complex phenomenon and can be caused by a number of clinical factors. Anesthetic risk factors for perioperative nerve injury include regional block technique, patient risk factors, and local anesthetic-induced neurotoxicity. Surgery can lead to nerve damage by use of tourniquets or by direct mechanical stress on nerves, such as traction, transection, compression, contusion, ischemia, and stretching. Current literature suggests that the majority of perioperative nerve injuries are unrelated to regional anesthesia. Besides the blockade of sodium channels which is responsible for the anesthetic effect, systemic local anesthetics can have a positive influence on the inflammatory response and the hemostatic system in the perioperative period. However, next to these beneficial effects, local anesthetics exhibit time and dose-dependent toxicity to a variety of tissues, including nerves. There is equivocal experimental evidence that the toxicity varies among local anesthetics. Even though the precise order of events during local anesthetic-induced neurotoxicity is not clear, possible cellular mechanisms have been identified. These include the intrinsic caspase-pathway, PI3K-pathway, and MAPK-pathways. Further research will need to determine whether these pathways are non-specifically activated by local anesthetics, or whether there is a single common precipitating factor.

Review
Acute-on-chronic liver failure (ACLF) is a recently defined syndrome characterised by acute decompensation of chronic liver disease, associated with organ failures and high mortality. ACLF is a common condition and may affect up to 30% of patients admitted to hospital for cirrhosis complications. Bacterial infections, alcoholism and reactivation of viral hepatitis are the most common precipitating factors in ACLF, although in up to 40% of patients no precipitating factor can be identified. Although the pathophysiology of ACLF is not completely understood, the presence of an excessive inflammatory response appears to play a key role. There is no specific treatment for patients with ACLF and management is based on organ support and liver transplantation. New treatment strategies based on liver support systems and immunomodulatory treatments are being evaluated but existing data are still limited.

Review
Exertional (exercise-induced) rhabdomyolysis is a potentially life threatening condition that has been the subject of research, intense discussion, and media attention. The causes of rhabdomyolysis are numerous and can include direct muscle injury, unaccustomed exercise, ischemia, extreme temperatures, electrolyte abnormalities, endocrinologic conditions, genetic disorders, autoimmune disorders, infections, drugs, toxins, and venoms. The objective of this article is to review the literature on exertional rhabdomyolysis, identify precipitating factors, and examine the role of the dietary supplement creatine monohydrate. PubMed and SPORTDiscus databases were searched using the terms rhabdomyolysis, muscle damage, creatine, creatine supplementation, creatine monohydrate, and phosphocreatine. Additionally, the references of papers identified through this search were examined for relevant studies. A meta-analysis was not performed. Although the prevalence of rhabdomyolysis is low, instances still occur where exercise is improperly prescribed or used as punishment, or incomplete medical history is taken, and exertional rhabdomyolysis occurs. Creatine monohydrate does not appear to be a precipitating factor for exertional rhabdomyolysis. Healthcare professionals should be able to recognize the basic signs of exertional rhabdomyolysis so prompt treatment can be administered. For the risk of rhabdomyolysis to remain low, exercise testing and prescription must be properly conducted based on professional standards.

Review
Long QT syndrome (LQTS) is an arrhythmogenic disorder characterized by repolarization abnormalities with a tendency to cause life threatening cardiac events. The first manifestation of the syndrome may be sudden death, therefore, early diagnosis and therapy is of great importance. LQTS can be congenital or acquired. The latter is most commonly seen in hospitalized patients and such individuals have an easily recognizable and reversible precipitating factor (electrolyte disturbances, certain drugs etc.). Congenital LQTS, a less prevalent condition, is considered to be part of the greater family of disorders called channelopathies. Extensive research over the past decade allowed better understanding of the underlying molecular mechanisms and unmasking of the genetic substrate of these patients. Both pharmacological and interventional therapies (left cardiac sympathetic denervation, ICDs) have been used in the treatment of congenital long-QT syndrome. This review will focus solely on the pharmacologic therapy of this potentially lethal inherited disorder summarizing current knowledge regarding b-blocker use, taking into account novel and more targeted approaches such as gene-specific therapy.
