Direct Fluconazole Disk Susceptibility Testing for Candida glabrata-Positive Blood Cultures.

Direct susceptibility testing from blood cultures has been reported to reduce the time interval between a positive blood culture to preliminary reporting of susceptibility and can underpin timely appropriate treatment of candidemia. The aim of this study was to evaluate direct susceptibility testing of Candida glabrata to fluconazole using disk diffusion compared to the Sensititre YeastOne broth microdilution-based method. We tested 83 isolates recovered from 93 spiked and prospective blood culture bottles. Comparison of the two methods showed excellent agreement, with no very major errors and only two major errors (2.4%). The accuracy of the fluconazole disk method was 97.6% (95% confidence interval [CI], 91.6 to 99.7), with a sensitivity of 100% (95% CI, 82.3 to 100) and a specificity of 96.9% (95% CI, 89.2 to 99.6). Direct antifungal disk susceptibility testing from blood cultures is a rapid and easy-to-perform method to determine fluconazole susceptibility of C. glabrata isolates and can be used safely to reduce susceptibility report time and improve clinical decision making regarding appropriate treatment.

The cardiovascular safety of antiobesity drugs-analysis of signals in the FDA Adverse Event Report System Database.

AIMS: Over the past several decades, many antiobesity drugs have been withdrawn from the market due to unanticipated adverse events, often involving cardiotoxicity. This study aimed to evaluate the presence of cardiovascular safety signals with currently marketed antiobesity drugs. METHODS: We used the US Food and Drug Administration Adverse Event Reporting System (FAERS) database and retrieved data from January 2013 through December 2018. We performed disproportionality analyses to detect cardiovascular safety signals with three antiobesity drugs recently approved for marketing: lorcaserin, naltrexone-bupropion, phentermine, and phentermine-topiramate. Three main cardiovascular outcomes were evaluated: valvular disorders, and pulmonary hypertension (PH) and other cardiovascular events (myocardial infarction, stroke, cardiovascular death, cardiac failure, and arrhythmia). RESULTS: During the evaluated period, a total of 6,787,840 adverse event reports were submitted to FAERS. Of these, 2687 involved lorcaserin, 3960 involved phentermine/phentermine-topiramate, and 2873 involved naltrexone-bupropion. Lorcaserin was associated with a significantly greater proportion of reports of valvular disorders (ROR = 4.39; 95% CI 2.72-5.07). None of the antiobesity drugs were associated with a safety signal for valvulopathy, PH, or other cardiovascular events. CONCLUSIONS: Our analyses revealed a signal for valvular disorders with lorcaserin and did not detect a safety signal for other cardiovascular events with recently approved antiobesity drugs. Further research is needed to explore and validate this signal.

Characteristics and Symptoms of App Users Seeking COVID-19-Related Digital Health Information and Remote Services: Retrospective Cohort Study.

BACKGROUND: Patient-facing digital health tools have been promoted to help patients manage concerns related to COVID-19 and to enable remote care and self-care during the COVID-19 pandemic. It has also been suggested that these tools can help further our understanding of the clinical characteristics of this new disease. However, there is limited information on the characteristics and use patterns of these tools in practice. OBJECTIVE: The aims of this study are to describe the characteristics of people who use digital health tools to address COVID-19-related concerns; explore their self-reported symptoms and characterize the association of these symptoms with COVID-19; and characterize the recommendations provided by digital health tools. METHODS: This study used data from three digital health tools on the K Health app: a protocol-based COVID-19 self-assessment, an artificial intelligence (AI)-driven symptom checker, and communication with remote physicians. Deidentified data were extracted on the demographic and clinical characteristics of adults seeking COVID-19-related health information between April 8 and June 20, 2020. Analyses included exploring features associated with COVID-19 positivity and features associated with the choice to communicate with a remote physician. RESULTS: During the period assessed, 71,619 individuals completed the COVID-19 self-assessment, 41,425 also used the AI-driven symptom checker, and 2523 consulted with remote physicians. Individuals who used the COVID-19 self-assessment were predominantly female (51,845/71,619, 72.4%), with a mean age of 34.5 years (SD 13.9). Testing for COVID-19 was reported by 2901 users, of whom 433 (14.9%) reported testing positive. Users who tested positive for COVID-19 were more likely to have reported loss of smell or taste (relative rate [RR] 6.66, 95% CI 5.53-7.94) and other established COVID-19 symptoms as well as ocular symptoms. Users communicating with a remote physician were more likely to have been recommended by the self-assessment to undergo immediate medical evaluation due to the presence of severe symptoms (RR 1.19, 95% CI 1.02-1.32). Most consultations with remote physicians (1940/2523, 76.9%) were resolved without need for referral to an in-person visit or to the emergency department. CONCLUSIONS: Our results suggest that digital health tools can help support remote care and self-management of COVID-19 and that self-reported symptoms from digital interactions can extend our understanding of the symptoms associated with COVID-19.

Prenatal exposure to selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors and risk for persistent pulmonary hypertension of the newborn: a systematic review, meta-analysis, and network meta-analysis.

BACKGROUND: There is a marked increase in the use of selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors in the last decade. Many newborns are likely to be exposed during pregnancy and labor. OBJECTIVE: We aimed to evaluate the association between exposure to selective serotonin reuptake inhibitors and serotonin norepinephrine reuptake inhibitors during pregnancy and the risk for persistent pulmonary hypertension of the newborn. We sought to compare the risk for persistent pulmonary hypertension of the newborn between specific selective serotonin reuptake inhibitor agents. STUDY DESIGN: MEDLINE, Embase, and Cochrane were searched up to July 2017. No language restrictions were applied. Search key words included: "SSRI," "SNRI," "pregnancy," "risk," "new-born," and "pulmonary hypertension." Retrospective cohort studies and case-control studies reporting the risk for persistent pulmonary hypertension of the newborn in the offspring of women exposed to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy, were extracted. Two independent researchers identified relevant data. Random effects meta-analysis was used to pool results. Odds ratios were calculated with subsequent 95% confidence intervals. Network meta-analysis was conducted, incorporating direct and indirect comparisons among different selective serotonin reuptake inhibitors. The primary outcome was risk for persistent pulmonary hypertension of the newborn after exposure to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy. RESULTS: A total of 11 studies were identified. A total of 156,978 women and their offspring were exposed to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy. Persistent pulmonary hypertension of the newborn was detected among 452 exposed offspring, representing an incidence rate of 2.9 cases per 1000 live births and a number needed to harm of 1000. The risk for persistent pulmonary hypertension of the newborn was significantly increased in the analysis of exposure to selective serotonin reuptake inhibitor/serotonin norepinephrine reuptake inhibitor in any trimester (odds ratio, 1.82; 95% confidence interval, 1.31-2.54; I2 = 72%), as well as in analysis restricted to exposure week >20 (odds ratio, 2.08; 95% confidence interval, 1.44-3.01; I2 = 76%). In network meta-analysis, sertraline was ranked most likely to have the lowest risk for persistent pulmonary hypertension of the newborn among the different selective serotonin reuptake inhibitors (P = .83). CONCLUSION: Exposure to selective serotonin reuptake inhibitors or serotonin norepinephrine reuptake inhibitors during pregnancy is associated with an increased risk for persistent pulmonary hypertension of the newborn. According to our findings, sertraline ranked as most likely to have the lowest risk for persistent pulmonary hypertension of the newborn compared to other selective serotonin reuptake inhibitors, suggesting it may have the best safety profile for use in pregnancy in this regard. Further studies are needed to fully establish these results.

Calcium Channel Blockers and the Risk for Lung Cancer: A Population-Based Nested Case-Control Study.

BACKGROUND: It has been suggested that calcium channel blockers (CCBs) may increase the risk of lung cancer; however, current evidence is conflicting and limited. OBJECTIVE: Investigate the associations between CCB use and lung cancer. METHODS: We conducted a population-based nested case-control study. A cohort was formed of patients prescribed their first antihypertensive agent from 2000 to 2014. CCB exposure information was obtained by identification of all prescriptions dispensed during study follow-up. Cases were patients newly diagnosed with lung cancer during follow-up. Each case was matched with 10 controls by age, sex, calendar year of cohort entry, and duration of follow-up. Multivariate conditional logistic regression was used to estimate odds ratios (ORs) with 95% CIs of lung cancer associated with ever use of CCBs. RESULTS: During a median follow-up of 6.2 years, we identified 4174 cases of lung cancer. Ever use of CCBs was associated with an increased risk of lung cancer (adjusted OR = 1.13; 95% CI = 1.06-1.21), when compared with the use of other antihypertensive drugs. A duration-response relation was observed, with the ORs gradually increasing with longer cumulative duration of CCB use (<5 years: OR = 1.12, 95% CI = 1.04-1.20; 5-10 years: OR = 1.22, 95% CI = 1.07-1.40; >10 years: OR = 1.33, 95% CI = 0.90-1.96; P trend < 0.001). Conclusion and Relevance: The results of this large population-based study indicate that the use of CCBs is associated with a modest but significant increase in the risk of lung cancer. This association appeared to increase with longer duration of use.

Management strategies of the interaction between direct oral anticoagulant and drug-metabolizing enzyme inducers.

Little is known regarding the management of direct oral anticoagulants (DOACs) in patients with enzyme-inducing drugs (EID). The use of EID may lead to sub-therapeutic concentrations of DOACs and to treatment failure. Thus, many patients on EIDs cannot benefit from the advantages of DOACs. This was a retrospective study, evaluating the management of hospitalized patients with DOACs. Characteristics of hospitalized patients with a prescription for DOACs, with and without EIDs, were summarized and evaluated, and management strategies addressing the potential interaction were documented, including the use of DOAC concentration monitoring. During the period evaluated, 1596 hospitalized patients with prescriptions for DOACs were identified. Most patients received apixaban (n = 1227, 77%), followed by rivaroxaban (240, 15%), and dabigatran (129, 8%). Twenty-two patients (1.4%) had concomitant EIDs. Demographic and clinical characteristics of hospitalized patients with DOACs were similar in those receiving EID and those not. Management strategies included stopping DOAC or EID (41%), and DOAC dose increase (14%). During management of these interactions, DOAC concentrations were measured for 11 of 22 patients and were below the 5th percentile of expected concentration for six of these patients. The management of patients with DOAC concentration measurement differed significantly from those without (p = 0.005), as they were much less likely to have one of the medications stopped and more often had the DOACs' dose increased. Among hospitalized patients with DOACs, EIDs are not rare. DOAC concentrations are often low in the presence of EIDs. DOAC concentration monitoring may be useful in settings requiring both DOAC and EIDs.

Prenatal Exposure to Acetaminophen and Risk for Attention Deficit Hyperactivity Disorder and Autistic Spectrum Disorder: A Systematic Review, Meta-Analysis, and Meta-Regression Analysis of Cohort Studies.

Acetaminophen is the analgesic and antipyretic most commonly used during pregnancy. Evidence of neurodisruptive properties is accumulating. Therefore, we sought to evaluate the risk for attention deficit hyperactivity disorder (ADHD) and autistic spectrum disorder (ASD) in the offspring of women exposed to acetaminophen during pregnancy. We searched MEDLINE, Embase, and Cochrane databases for relevant studies up to January 2017. Data were independently extracted and assessed by 2 researchers. Seven eligible retrospective cohorts included 132,738 mother-child pairs, with follow-up periods ranging from 3 to 11 years. The pooled risk ratio for ADHD was 1.34 (95% confidence interval (CI): 1.21, 1.47; I2 = 72%); for ASD, the risk ratio was 1.19 (95% CI: 1.14, 1.25; I2 = 14%), and for hyperactivity symptoms, it was 1.24 (95% CI: 1.04, 1.43; I2 = 93%). In meta-regression analysis, the association between exposure and ADHD increased with the child's age upon follow-up (ß = 0.03, 95% CI: 0.00, 0.07) and with the mean duration of exposure (ß = 0.00, 95% CI: 0.00, 0.01). The available data is of observational nature only. Studies differed widely in exposure and outcome assessment. Acetaminophen use during pregnancy is associated with an increased risk for ADHD, ASD, and hyperactivity symptoms. These findings are concerning; however, results should be interpreted with caution given that the available evidence consists of observational studies and is susceptible to several potential sources of bias.

The hemodynamic response to constant dobutamine infusion: the effect of ADRB1 389 polymorphism and sex.

OBJECTIVES: Prolonged activation of the ß-1 adrenergic receptor (ADRB1) is associated with receptor desensitization. This process has been suggested to have important pathophysiological and clinical implications in conditions such as congestive heart failure. The contribution of genetic factors to this process is a subject of ongoing research. We have previously shown that the ADRB1 389 polymorphism affects the response to incremental dose infusion of the ADRB agonist dobutamine. The aim of the current study was to determine whether the ADRB1 389 polymorphism affects the hemodynamic response to constant dose infusion of dobutamine in healthy patients. PATIENTS AND METHODS: Healthy patients were recruited according to their ADRB1 49 and 389 genotypes [15 Arg389Arg, 10 Gly389Arg, and 10 Gly389Gly patients (all Ser49Ser), 21 men and 14 women]. Following a standardized protocol of dose increase, 6 mcg/kg/min dobutamine was infused over 2 h. Heart rate (HR), blood pressure (BP), and active plasma renin (PR) were measured. Standardized exercise (1 min) was performed at three time points during infusion. RESULTS: In all patients, resting systolic BP was significantly decreased during infusion [144.4±11.5 vs. 140.3±12.2 mmHg (mean±SD), P=0.007]. There was no change in HR, and PR following 120 min of dobutamine infusion. ADRB1 389 genotypes were not associated with HR, systolic BP, and PR changes during dobutamine infusion (all P>0.05, repeated measures analysis of variance). Sex was associated with response to dobutamine. Among women, but not in men, resting HR significantly increased, and diastolic blood pressure (DBP) significantly decreased during dobutamine infusion [HR: 76.0±7.3 to 86.3±17.5 beats per minute (P=0.023), and DBP 78.5±8.49 mmHg to 72.36±6.16 (P=0.041) (repeated measures analysis of variance)]. CONCLUSION: In healthy patients, the ADRB1 389 genotype was not associated with hemodynamic changes during constant dobutamine infusion. In women, but not in men, HR significantly increased and DBP decreased during 2 h of infusion.

Systematic Review, Meta-analysis, and Network Meta-analysis of the Cardiovascular Safety of Macrolides.

Studies reporting an increased risk for cardiac toxicities with macrolide antibiotics have raised concern regarding their cardiovascular safety. We sought to assess the cardiac safety of macrolide antibiotics as a class and of the individual agents by conducting a systematic review and network meta-analysis. Medline, Embase, and the Cochrane Library were searched up to February 2018 for studies reporting on cardiovascular outcomes with macrolides. We followed the PRISMA 2009 guidelines for data selection and extraction. Outcomes were pooled using random-effects models and odds ratios (OR), and 95% confidence intervals (CI) were calculated for arrhythmia, cardiovascular death, and myocardial infarction (MI). A total of 33 studies and data on 22,601,032 subjects were retrieved and included in the current meta-analyses. Macrolide use was not associated with the risk of arrhythmia or cardiovascular mortality. In the primary analysis, macrolide use was associated with a small but statistically significant 15% increase in risk for MI (OR = 1.15 [95% CI, 1.01 to 1.30]). In indirect network meta-analysis, erythromycin and clarithromycin were ranked considerably more likely to be associated with a higher risk for MI and significantly associated with increased risk of MI compared to azithromycin (OR = 1.58 [95% CI, 1.18 to 2.11] and OR = 1.41 [95% CI, 1.11 to 1.81], respectively). Our findings indicate that macrolide antibiotics as a group are associated with a significant risk for MI but not for arrhythmia and cardiovascular mortality. Among the macrolides, erythromycin and clarithromycin were associated with a greater risk of MI. However, it is possible that the association between macrolide use and risk of MI is the result of residual confounding.

Cognition- and Dementia-Related Adverse Effects With Sacubitril-Valsartan: Analysis of the FDA Adverse Event Report System Database.

BACKGROUND: Because neprilysin is involved in the degradation of amyloid-beta, there is concern that the angiotensin-neprilysin inhibitor sacubitril-valsartan could increase the risk for dementia. METHODS: We analyzed adverse event cases submitted to the Food and Drug Administration Adverse Event Report System from July 2015 to March 2017. Cognition- and dementia-related adverse event cases were defined with the use of broad and narrow structured medical queries. RESULTS: During the period evaluated, 9,004 adverse event reports (out of a total of 2,249,479) involved the use of sacubitril-valsartan. Based on the broad definition, sacubitril-valsartan was associated with cognition- and dementia-related adverse events in 459 reports (5.1%), but this was lower than the proportion of these reports among other medications (6.6%, reporting odds ratio [ROR] 0.72, 95% confidence interval [CI] 0.65-0.79). Restricting the comparison to cases with age >60 years and with the use of a comparator group with heart failure resulted in no association between sacubitril-valsartan and dementia-related adverse events, with the use of both the broad and the narrow definitions (ROR 0.87, 95% CI 0.76-1.02, and ROR 1.06, 95% CI 0.4-3.16, respectively). CONCLUSION: Sacubitril-valsartan is not associated with a disproportionately high rate of short-term dementia-related adverse effect reports. Long-term studies assessing cognitive outcomes are required to better establish the medication's cognition effects.

Pregnancy Outcomes Following Exposure to Quinolone Antibiotics - a Systematic-Review and Meta-Analysis.

PURPOSE: Quinolones, and the fluoroquinolones subgroup, are a class of antibiotics commonly used for the treatment of a wide variety of infections. However, their safety profile in pregnant women is controversial. The association between fluoroquinolones and arthropathy was primarily described in immature animals, and only rarely in humans, yet it has led to the restricted use of quinolones during pregnancy. We aimed to assess their safety during pregnancy. METHODS: A systematic review and meta-analysis assessing the safety of quinolone exposure during any time of pregnancy, and during first trimester alone, was performed. The systematic review was performed using MEDLINE and EMBASE, and followed the PRISMA guidelines. Pooled effect sizes with corresponding 95% confidence intervals (CI) were calculated using random effects models, comparing fetal outcomes of quinolone exposed and non-exposed pregnancies. Only cohort and case control studies were included in the meta-analysis. RESULT: Twelve studies met the inclusion criteria. Exposure to quinolones during first trimester was not associated with an increased risk for birth defects (pooled odds ratio (OR) = 0.89, 95% CI 0.72-1.09, I2 = 0%), stillbirth (OR = 1.32, 95% CI 0.33-5.34, I2 = 16%), preterm birth (OR = 1.10, 95% CI 0.83-1.48, I2 = 41%) and low birth weight (OR = 1.29, 95% CI 0.54-3.12, I2 = 67%). CONCLUSION: The use of quinolones during the first-trimester of pregnancy was not associated with an increased risk of birth defects, stillbirths, preterm births or low birth weight. STUDY REGISTRY: PROSPERO CRD42017060573.

Gender Differences in Efficacy and Safety of Direct Oral Anticoagulants in Atrial Fibrillation: Systematic Review and Network Meta-analysis.

BACKGROUND: Studies indicate that women with atrial fibrillation (AF) are less likely to receive anticoagulants despite their higher risk of stroke compared with men. OBJECTIVE: To evaluate whether the efficacy and safety of direct oral anticoagulants (DOACs) differ in women with AF as compared with men. Our secondary aim was to examine gender differences regarding the safety and efficacy of specific DOACs. DATA SOURCES: MEDLINE, EMBASE, Cochrane, and ClinicalTrials.gov were searched through March 2017. STUDY SELECTION AND DATA EXTRACTION: Randomized clinical trials that reported on major bleeding and stroke with DOACs in women and men with AF were included. Meta-analysis and network meta-analysis was performed. DATA SYNTHESIS: Five trials met the inclusion criteria. Among 66 389 patients, 37.8% were women. Women treated with DOACs were at higher risk of stroke and systemic embolism compared with men (RR = 1.19; 95% CI = 1.04-1.35; I2 = 10%) but there was a significantly lower risk of major bleeding in women compared with men (RR = 0.86; 95% CI = 0.78-0.94; I2 = 0%). Network meta-analyses suggested differences between various DOACs in men and women. LIMITATIONS: Patient-level data enabling control for differences in baseline risk and head-to-head comparisons between DOACs were not available. Relevance to Patient Care and Clinical Practice: Undertreatment with DOACs among women cannot be justified. CONCLUSION: Women treated with DOACs had a lower rate of major bleeding and higher rate of stroke and systemic emboli compared with men. Further investigation of DOACs, including differences between the DOACs in specific populations is warranted.

Z-drugs and risk for falls and fractures in older adults-a systematic review and meta-analysis.

Objective: zolpidem, zopiclone, eszopiclone and zaleplon, also known as 'Z-drugs', are commonly used as alternatives to benzodiazepines (BZDs) to treat insomnia. Z-drugs are often perceived as safer than BZDs. We conducted a systematic review and meta-analysis evaluating the association between Z-drugs and fracutres, falls and injuries. Methods: a systematic review was performed using MEDLINE, EMBASE and ClinicalTials.gov. Pooled effect-sizes were calculated comparing Z-drugs users with non-users, using fixed and random-effect models with corresponding 95% confidence of intervals (CI). Results: we identified 14 eligible studies reporting on the association between Z-drugs and outcomes of interest. Z-Drugs were associated with a statistically significant increased risk for fractures, with evidence of considerable heterogeneity (OR = 1.63; 95% CI: 1.42-1.87; I2 = 90%; n = 830,877). Likewise, there was a trend suggesting a 2-fold increase in the odds for falls, however, this result was not statistically significant and there was evidence of considerable heterogeneity (OR = 2.40; 95% CI: 0.92-6.27; I2 = 95%; n = 19,505). In an analysis assessing the risk for injuries following exposure to zolpidem we found a statistically significant increased risk of injuries, with no evidence of heterogeneity (OR = 2.05; CI 95%: 1.95-2.15; I2 = 0; n = 160,502). Results were similar in sensitivity analyses, including analyses restricted to studies of high-quality, studies with control groups suffering from insomnia, and with specific Z-drugs. Conclusion: our results indicate that Z-drugs are associated with an increased risk for fractures, and suggest a possible increased risk for falls and injuries as well. However, studies included were observational and susceptible to confounding. Physicians should consider these potential risks before prescribing these medications in older adults.

Drug interaction as a predictor of direct oral anticoagulant drug levels in atrial fibrillation patients.

Data are limited on the effects of drug interactions on direct-acting oral anticoagulant (DOAC) levels. We evaluated the effects of the use of interacting drugs on DOAC levels in patients with atrial fibrillation (AF). We reviewed data of AF patients tested for DOAC levels in 2013-2017. The primary outcomes were drug levels exceeding the expected steady-state range, and in the highest quartile. A multivariate analysis was performed to evaluate the correlation of treatment by the use of interacting drugs, CYP3A4 and P-glycoprotein (P-gp) inhibitors, with the primary outcomes. Overall, 147 patients underwent DOAC level measurement [dabigatran (n = 31), rivaroxaban (n = 29), apixaban (n = 87)]. Thirty-three (22.4%) had drug levels exceeding the expected range. Seventy-nine (53.7%) patients were treated with at least one interacting drug. In multivariate analysis, the concomitant use of interacting drugs was an independent predictor for drug levels exceeding the expected range (OR 3.3, 95% CI 1.20-9.05). The defined daily dose of the interacting drug correlated positively with DOAC levels (r = 0.29, P = 0.001). Co-treatment with interacting drugs was associated with extremely high levels of dabigatran, (OR 16.6, 95% CI 1.29-215.18) but not of the other DOAC examined. Concomitant use of interacting drugs is associated with high DOAC levels in patients with AF. Further investigation is warranted to establish the differences between specific DOAC, evaluate the effect on patient outcomes, and characterize the role of DOAC monitoring in this setting.

Clinical Spectrum and Mechanism of Acute Kidney Injury in Patients with Diabetes Mellitus on SGLT-2 Inhibitors.

BACKGROUND: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) (such as canagliflozin, empagliflozin, and dapagliflozin) are widely used to treat patients with type 2 diabetes mellitus (T2DM) to improve glycemic, cardiovascular and renal outcomes. However, based on post-marketing data, a warning label was added regarding possible occurrence of acute kidney injury (AKI). OBJECTIVES: To describe the clinical presentation of T2DM patients treated with SGLT2i who were evaluated for AKI at our institution and to discuss the potential pathophysiologic mechanisms. METHODS: A retrospective study of a computerized database was conducted of patients with T2DM who were hospitalized or evaluated for AKI while receiving SGLT2i, including descriptions of clinical and laboratory characteristics, at our institution. RESULTS: We identified seven patients in whom AKI occurred 7-365 days after initiation of SGLT2i. In all cases, renin-angiotensin-aldosterone system blockers had also been prescribed. In five patients, another concomitant nephrotoxic agent (injection of contrast-product, use of nonsteroidal anti-inflammatory drugs or cox-2 inhibitors) or occurrence of an acute medical event potentially associated with AKI (diarrhea, sepsis) was identified. In two patients, only the initiation of SGLT2i was evident. The mechanisms by which AKI occurs under SGLT2i are discussed with regard to the associated potential triggers: altered trans-glomerular filtration or, alternatively, kidney medullary hypoxia. CONCLUSIONS: SGLT2i are usually safe and provide multiple benefits for patients with T2DM. However, during particular medical circumstances, and in association with usual co-medications, particularly if baseline glomerular filtration rate is decreased, patients treated with SGLT2i may be at risk of AKI, thus warranting caution when prescribed.

Association of Acetaminophen and Ibuprofen Use With Wheezing in Children With Acute Febrile Illness.

BACKGROUND: Many infants and children receive acetaminophen and/or ibuprofen during febrile illness. Previously, some studies have linked acetaminophen and ibuprofen use to wheezing and exacerbation of asthma symptoms in infants and children. OBJECTIVE: To assess whether acetaminophen or ibuprofen use are associated with wheezing in children presenting to the emergency department (ED) with febrile illness. METHODS: This was a cross-sectional study of children who presented with fever to the pediatric ED between 2009 and 2013. The data were collected from questionnaires and from the children's medical files. Patients with wheezing in the ED were compared with nonwheezing patients. Associations between medication use and wheezing were assessed using univariate and multivariate analyses. The multivariate analysis adjusted for potential confounding variables (ie, age, atopic dermatitis, allergies, smoking, antibiotics use, etc) via propensity scores. RESULTS: During the study period, 534 children admitted to the ED met our inclusion criteria, of whom 347 (65%) were included in the study. The use of acetaminophen was similar in children diagnosed with wheezing compared with those without wheezing (n = 39, 81.3%, vs n = 229, 82.7%, respectively). Ibuprofen use was significantly lower in children diagnosed with wheezing (n = 22, 52.4%, vs n = 168, 69.4%, respectively). In multivariate analysis, acetaminophen was not associated with a higher rate of wheezing during acute febrile illness (adjusted odds ratio [OR] = 0.76, 95% CI = 0.24- 2.39), whereas ibuprofen was associated with a lower risk of wheezing (adjusted OR = 0.36, 95% CI = 0.13-0.96). CONCLUSIONS: Our study suggests that acetaminophen and ibuprofen are not associated with increased risk for wheezing during acute febrile illness.

Role of vasopressin and terlipressin in refractory shock compared to conventional therapy in the neonatal and pediatric population: a systematic review, meta-analysis, and trial sequential analysis.

BACKGROUND: Vasopressin (AVP) and terlipressin (TP) have been used as last-line therapy in refractory shock in children. However, the efficacy and safety profiles of AVP and TP have not been determined in pediatric refractory shock of different origins. We aimed to assess the efficacy and safety of the addition of AVP/TP therapy in pediatric refractory shock of all causes compared to conventional therapy with fluid resuscitation and vasopressor and inotropic therapy. METHODS: We conducted a systematic review, meta-analysis, and trial sequential analysis (TSA) comparing AVP and TP to conventional therapy. MEDLINE, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched up to February 2016. The systematic review included all reports of AVP/TP use in the pediatric population. Reports of clinical trials were pooled using random-effects models and TSA. Main outcomes were mortality and tissue ischemia. RESULTS: Three randomized controlled trials and five "before-and-after clinical" trials (without comparator) met the inclusion criteria. Among 224 neonates and children (aged 0 to 18 years) with refractory shock, 152 received therapy with AVP or TP. Pooled analyses showed no association between AVP/TP treatment and mortality (relative risk (RR),1.19; 95% confidence interval (CI), 0.71-2.00), length of stay in the pediatric intensive care unit (PICU) (mean difference (MD), -3.58 days; 95% CI, -9.05 to 1.83), and tissue ischemia (RR, 1.48; 95% CI, 0.47-4.62). In TSA, no significant effect on mortality and risk for developing tissue ischemia was observed with AVP/TP therapy. CONCLUSION: Our results emphasize the lack of observed benefit for AVP/TP in terms of mortality and length of stay in the PICU, and suggest an increased risk for ischemic events. Our TSA suggests that further large studies are necessary to demonstrate and establish benefits of AVP/TP in children. PROSPERO registry: CRD42016035872.
