Abstract
BACKGROUND Only about 50% of intensive care unit (ICU) patients reach a free trough concentration above MIC (100% fT > MIC) of beta-lactam antibiotics. Although dose adjustments based on therapeutic drug monitoring (TDM) could be beneficial, TDM is not widely available. We investigated serum creatinine-based estimated GFR (eGFR) as a rapid screening tool to identify ICU patients at risk of insufficient exposure. METHOD Ninety-three adult patients admitted to four ICUs in southeast Sweden treated with piperacillin/tazobactam, meropenem, or cefotaxime were included. Beta-lactam trough concentrations were measured. The concentration target was set to 100% fT > MICECOFF (2, 4, and 16 mg/L based on calculated free levels for meropenem, cefotaxime, and piperacillin, respectively). eGFR was primarily determined via Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) and compared to three other eGFR equations. Data was analysed using logistic regression and receiver operative characteristic (ROC) curves. RESULTS With intermittent standard dosing, insufficient exposure was common in patients with a relative eGFR ≥48mL/min/1.73m2 [85%, (45/53)], particularly when treated with cefotaxime [96%, (24/25)]. This eGFR cut-off had a sensitivity of 92% and specificity of 82% (AUC 0.871, p < 0.001) in identifying insufficient exposure. In contrast, patients with eGFR <48mL/min/1.73m2 had high target attainment [90%, (36/40)] with a wide variability in drug exposure. There was no difference between the four eGFR equations (AUC 0.866-0.872, cut-offs 44-51 ml/min/1.73m2). CONCLUSION Serum creatinine-based eGFR is a simple and widely available surrogate marker with potential for early identification of ICU patients at risk of insufficient exposure to piperacillin, meropenem, and cefotaxime.

Abstract
BACKGROUND Only some studies have directly compared and analyzed the roles of activated partial thromboplastin time (aPTT) and activated clotting time (ACT) in coagulation monitoring during argatroban administration. OBJECTIVES This study aims to assess the correlation of argatroban dose with ACT and aPTT values and to identify the optimal coagulation test for argatroban dose adjustment. METHODS We evaluated 55 patients on extracorporeal membrane oxygenation (ECMO) who received argatroban for more than 72 hours. The correlation between argatroban dose and aPTT and ACT values was evaluated. To compare argatroban dose and bleeding events according to liver dysfunction, the patients were divided into 2 groups based on alanine aminotransferase and total bilirubin. RESULTS Among the 55 patients, a total of 459 doses and coagulation tests were evaluated. The aPTT and ACT values showed a weak correlation with argatroban dose, with the Pearson correlation coefficients of 0.261 (P < 0.001) and 0.194 (P = 0.001), respectively. The agreement between the target 150 to 180 seconds for ACT and 55 to 75 seconds for aPTT was observed in 140 patients (46.1%). Twenty-four patients (43.6%) had liver dysfunction when they started argatroban. The median argatroban dose was lower in the liver dysfunction group than in the control group (0.094 mcg/kg/min vs 0.169 mcg/kg/min, P = 0.020). Difference was not observed between the 2 groups in the amount of red blood cell (0.47 vs 0.43 pack, P = 0.909) and platelet (0.60 vs 0.08 pack, P = 0.079) transfusion per day. CONCLUSION AND RELEVANCE A weak correlation was observed between argatroban dose and the aPTT and ACT values. However, the agreement between aPTT and ACT was only 46.1% regarding the scope of target range. Further research is necessary to determine how to assess the optimal argatroban dose for patients administered argatroban while undergoing ECMO at the intensive care unit.

Abstract
BACKGROUND Selective serotonin reuptake inhibitors (SSRIs) have been associated with an increased risk of upper gastrointestinal bleeding (UGIB) in older patients but little is known about the risk associated with individual SSRI drugs and doses. AIMS To quantify the risk of UGIB in relation to individual SSRI use in older adults. METHODS We conducted a nested case-control study within a cohort of 9565 patients aged ⩾65 years prescribed SSRIs from 2000 to 2013 using claims data of universal health insurance in Taiwan. Incident cases of UGIB during the follow-up period were identified and matched with three control subjects. Conditional logistic regression was used to estimate the odds ratio (OR) of UGIB associated with individual SSRI use and cumulative dose. RESULTS UGIB risk increased with the increasing cumulative doses of SSRIs (adjusted OR: 1.28, 95% confidence interval (CI): 1.02-1.62 for the highest vs. the lowest tertile). Compared with users of other SSRIs, fluoxetine users were at an increased risk of UGIB (adjusted OR: 1.25, 95% CI: 1.03-1.50) with a dose-response manner, whereas paroxetine users had 29% decreased odds (95% CI: 0.56-0.91). The increased risk was only observed among current fluoxetine users. CONCLUSIONS Fluoxetine therapy was associated with an increased risk of UGIB in a dose-response manner among older adults.

Abstract
Background We performed a meta-analysis to compare the effects of high-dose (80 mg/day) versus low-dose (40 mg/day) proton pump inhibitors (PPIs) on gastrointestinal ulcer bleeding. Methods We retrieved studies of randomized controlled trials of PPIs administered according to different schedules for the treatment of gastrointestinal ulcer bleeding from Medline, Embase, Web of Science, Clinical Trials, and the Cochrane Database in April 2020. Results Nine randomized controlled trials including 2329 patients were included in this meta-analysis. There were no significant differences in the incidences of re-bleeding, operation intervention, postoperative mortality, and length of hospital stay between the low-dose and high-dose groups. However, the blood transfusion volume was significantly higher in the high-dose group. Conclusion Compared with low-does PPIs, high-dose PPIs had no effect on the incidence of re-bleeding, operation intervention, or postoperative mortality, and did not reduce hospital stay in patients treated with endoscopic hemostasis for gastrointestinal bleeding.

Abstract
BACKGROUND Intradermal therapy (mesotherapy) is a technique used to inject drugs into the surface layer of the skin. The intradermal micro deposit allows to modulate the kinetics of drugs, slowing down its absorption and prolonging the local mechanism of action. This technique is applied in the treatment of some forms of localized pain when a systemic drug-saving effect is useful, when it is necessary to synergize with other pharmacological or non-pharmacological thera-pies, when other therapies have failed or cannot be used. AIM The purpose of our study was to evaluate the effect of a mixture with respect to its lower concentration. We also wanted to evaluate the number of sessions needed to reach the therapeutic goal (50% reduction in pain from baseline) in patients with acute or chronic neck pain. METHOD We analyzed retrospectively data from 62 patients with cervicobrachial pain treated with intradermal drugs. Group A received a mixture of drugs; group B received half the dose of drugs. RESULTS Patients who received a lower concentration of drugs achieved similar results to those who received a higher dose. The therapeutic goal was achieved on average with 3.5 + 1.7 sessions on a weekly basis (min 1; max 9). Subjects in group A required 4+1.7 treatments (min 1; max 9), while subjects in group B required 3+1.5 treatments (min 1; max 7). CONCLUSIONS Our study confirms that even a lower dose of drugs can induce a clinically useful result. This study confirms that the useful effect of mesotherapy is only partly due to the pharmacological action. Further randomized prospective studies are needed to standardize the technique in the various pain syndromes, but it is recommended to follow the guidelines of the Italian Society of Mesotherapy to ensure patients receive appropriate treatment.

Abstract
The efficacy and safety of a drug is dose or exposure related, and both are used to assess the benefit-risk balance of a given drug and ultimately to decide on the specific drug license, including its dose and indication(s). Unfortunately, both efficacy and safety are much more difficult to establish in neonates, resulting in very few drugs licensed for use in this vulnerable population. This review will focus on dose-related adverse events in neonates. Besides the regulatory classification on seriousness, adverse event assessment includes aspects related to signal detection, causality, and severity. Disentangling confounders from truly dose-related adverse drug events remains a major challenge, as illustrated for drug-induced renal impairment, drug-induced liver injury, and neurodevelopmental outcome. Causality assessment, using either routine tools (Naranjo algorithm, World Health Organization's Uppsala Monitoring Center causality tool) or a Naranjo algorithm tailored to neonates, still does not sufficiently and reliably document causality in neonates. Finally, very recently, a first neonatal severity-grading tool for neonates has been developed. Following the development of advanced pharmacokinetic approaches and techniques to predict and assess drug exposure, additional efforts are needed to truly and fully assess dose adverse drug events. To further operationalize the recently developed tools on causality and severity, reference databases on a palette of biomarkers and outcome variables and their covariates are an obvious next step. These databases should subsequently be integrated in modeling efforts to truly explore safety outcome, including aspects associated with or caused by drug dose or exposure.

Abstract
Antibiotic concentrations vary dramatically in the body and the environment. Hence, understanding the dynamics of resistance evolution along antibiotic concentration gradients is critical for predicting and slowing the emergence and spread of resistance. While it has been shown that increasing the concentration of an antibiotic slows resistance evolution, how adaptation to one antibiotic concentration correlates with fitness at other points along the gradient has not received much attention. Here, we selected populations of Escherichia coli at several points along a concentration gradient for three different antibiotics, asking how rapidly resistance evolved and whether populations became specialized to the antibiotic concentration they were selected on. Populations selected at higher concentrations evolved resistance more slowly but exhibited equal or higher fitness across the whole gradient. Populations selected at lower concentrations evolved resistance rapidly, but overall fitness in the presence of antibiotics was lower. However, these populations readily adapted to higher concentrations upon subsequent selection. Our results indicate that resistance management strategies must account not only for the rates of resistance evolution but also for the fitness of evolved strains.

Abstract
BACKGROUND Necrotizing enterocolitis (NEC) is the most common acquired gastrointestinal emergency in premature infants. This study aimed to investigate the protective effect and mechanism of epidermal growth factor (EGF) on NEC in a neonatal rat model. METHODS We randomly divided 50 newborn SD rats into a control group, NEC group, NEC + 50 ng/mL EGF group, NEC + 500 ng/mL EGF group, and NEC + 1,000 ng/mL EGF group, with 10 cases in each group. The appearance of intestinal tissue, physiological status score, inflammatory factor level, HE staining, and pathological score were used to evaluate the protective effect. A one cm tissue sample from the proximal ileum of the ileocecal area of five rats from the NEC group and the group that showed a significant protective effect were extracted for transcriptome sequencing. RESULTS The levels of IL-1β and IL-6 in the intestinal mucosa in the NEC + 500 ng/mL EGF group were significantly lower than those in the NEC + 1,000 ng/mL EGF group (P<0.05). Transcriptome sequencing suggested that EGF effects the intestinal barrier, apoptosis, and inflammation of the NEC intestine. CONCLUSIONS We conclude that the oral administration of 500 ng/mL EGF effectively inhibits intestinal inflammation in NEC neonatal rat models, thereby affecting the barrier function of the intestinal tract.

Abstract
Objectives: To estimate the frequency of manipulations of all tablets and capsules prescribed for children in a teaching and tertiary children's hospital in China over the course of 1 month. Moreover, hypothetical reduction of manipulation according to the availability of low-strength tablets/capsules licensed by the Chinese National Medical Products Administration (CNMPA) was evaluated. Methods: Information on all tablets and capsules prescribed in the hospital from March 17 to April 16, 2019 was collected. It was assumed that tablets or capsules were manipulated if the prescribed dose would have required only a proportion of the intact dose form. Manipulation typically includes splitting or crushing tablets, opening capsules and dispersing in water, or combinations of these method. Moreover, we defined an "avoidable manipulation," when the dose could be rounded and/or when alternative products with a reduced strength or in liquid formulation were available in the hospital, and a "inappropriate manipulation," which involved manipulated medications with a direct contraindication for any manipulation, such as those with a narrow therapeutic index or hazardous ingredients, or modified release dosage-forms. The frequencies of total, avoidable, and inappropriate manipulation were estimated, along with the hypothetical reduction of manipulation according to the availability of CNMPA-approved drug doses. Results: A total of 17,123 prescriptions for 142 medications were identified to have required a manipulation among 78,366 prescriptions administered during the study period, with 43 different proportions of subdivisions, ranging from a 19/20 to 1/180 product strength reduction. Half, quarter, and trisection were the most common subdivisions administered. Overall, 19% of the manipulated prescriptions were determined to be avoidable, and 19% of the manipulations involved medications with a clear recommendation to not manipulate. In addition, 21% of the manipulated prescriptions could have been potentially avoided if all of the approved preparations with the lowest strength would have been available at the hospital. Any manipulations undertaken were carried out by pharmacists and family care givers. Conclusions: More than 20% of tablets and capsules prescriptions need manipulated, included a high incidence of avoidable and inappropriate manipulation.

Abstract
Objective To investigate the treatment efficacy of ultra-low-dose bevacizumab for cerebral radiation necrosis. Methods Patients with cerebral radiation necrosis after stereotactic radiotherapy (SRT) confirmed by imaging were included. Bevacizumab (1 mg/kg, once every three weeks, for at least three continuous treatments) was administered. The primary endpoints included change in cerebral necrosis symptoms, volume of intracranial edema, and changes in MRI signals. The secondary endpoints were adverse reactions of bevacizumab treatment. Results In total, 21 patients were included in this study, all of whom received SRT between December 2016 and February 2019, developed cerebral radiation necrosis, and were treated with bevacizumab. Twenty patients were symptomatic from radiation necrosis, and the symptoms were alleviated in 18 patients (90%). Twenty patients had intracranial edema, and the grade of edema index (EI) was improved in 19 patients (95%). The intensity of the intracranial-enhanced MRI signals was significantly reduced in 20 patients (95.24%). The adverse reactions of bevacizumab treatment were mild, and no adverse reactions more severe than grade 2 were found. Conclusion The preliminary results showed that ultra-low-dose bevacizumab had high efficacy for treating cerebral radiation necrosis, and could be a valid alternative to the standard-dose bevacizumab. Clinical registry Chinese clinical trial registry (ChiCTR-IOD-16009803).

Abstract
BACKGROUND The first-line drugs for the treatment of non-valvular atrial fibrillation (AF) are non-vitamin K antagonist oral anticoagulants (NOACs), which are preferred over vitamin K antagonists (VKAs). There is some evidence that there are dis-crepancies between everyday clinical practice and the guidelines. AIM The study aimed to compare the characteristics of patients on VKAs, dabigatran, and rivaroxaban in everyday practice (i.e. baseline characteristics, drug doses, risk factors for bleeding and thromboembolic events). Additionally, we assessed the frequency of prescription of different oral anticoagulants (OACs) in recent years. METHODS This study consisted of data from the multicentre CRAFT (MultiCentre expeRience in AFib patients Treated with OAC) study (NCT02987062). This was a retrospective analysis of hospital records of AF patients (hospitalised in the years 2011-2016) treated with VKAs (acenocoumarol, warfarin) and NOACs (dabigatran, rivaroxaban). A total of 3528 patients with non-valvular AF were enrolled in the CRAFT study. RESULTS The total cohort consisted of 1973 patients on VKA, 504 patients on dabigatran, and 1051 patients on rivaroxaban. Patients on rivaroxaban were older (70.5 ± 13.1 years) and more often female (47.9%), compared with those on VKAs (67.0 ± 12.8 years, p < 0.001; 35.5%, p < 0.001) and on dabigatran (66.0 ± 13.9 years, p < 0.001; 38.9%, p = 0.001). Among NOACs, patients with persistent and permanent AF were more likely to receive rivaroxaban (54.7% and 73.4%, re-spectively) than dabigatran (45.3%, p < 0.001 and 26.6%, p = 0.002, respectively). Patients on rivaroxaban had higher risk of thromboembolic events (CHA2DS2VASc 3.9 ± 2.0, CHADS2 2.2 ± 1.4) than those on VKAs (3.3 ± 2.0, 1.9 ± 1.3) and on dabigatran (3.1 ± 2.0, 1.8 ± 1.3). Patients on rivaroxaban had also a higher rate of prior major bleeding (11.2%) than those on VKAs (6.7%, p < 0.001) and on dabigatran (7.3%, p = 0.02). Patients on lower doses of dabigatran and rivaroxaban had a significantly higher risk of thromboembolic and bleeding events. Use of VKAs in the year 2011 was reported in over 96% of patients on OACs, but this proportion decreased to 34.6% in 2016. In the last analysed year (2016) AF patients were treated mainly with NOACs - dabigatran (24.2%) and rivaroxaban (41.3%). CONCLUSIONS The prescription of VKAs declined significantly after the introduction of NOACs. Patients treated with different OACs demonstrated a distinct baseline clinical profile. The highest risk of thromboembolic events and incidence of major bleedings was observed in patients on rivaroxaban, in comparison to patients on VKAs and dabigatran. Among NOACs, patients treated with lower doses of dabigatran and rivaroxaban were older and had a significantly higher risk of thromboembolic and bleeding events.

Abstract
Drug-induced liver injury (DILI), although rare, is a frequent cause of adverse drug reactions resulting in warnings and withdrawals of numerous medications. Despite the research community's best efforts, current testing strategies aimed at identifying hepatotoxic drugs prior to human trials are not sufficiently powered to predict the complex mechanisms leading to DILI. In our previous studies, we demonstrated lipophilicity and dose to be associated with increased DILI risk and, and in our latest work, we factored reactive metabolites into the algorithm to predict DILI. Given the inconsistency in determining the potential for drugs to cause DILI, the present study comprehensively assesses the relationship between DILI risk and lipophilicity and the extent of metabolism using a large published dataset of 1036 Food and Drug Administration (FDA)-approved drugs by considering five independent DILI annotations. We found that lipophilicity and the extent of metabolism alone were associated with increased risk for DILI. Moreover, when analyzed in combination with high daily dose (≥100 mg), lipophilicity was statistically significantly associated with the risk of DILI across all datasets (p < 0.05). Similarly, the combination of extensive hepatic metabolism (≥50%) and high daily dose (≥100 mg) was also strongly associated with an increased risk of DILI among all datasets analyzed (p < 0.05). Our results suggest that both lipophilicity and the extent of hepatic metabolism can be considered important risk factors for DILI in humans, and that this relationship to DILI risk is much stronger when considered in combination with dose. The proposed paradigm allows the convergence of different published annotations to a more uniform assessment.

Abstract
BACKGROUND The dose requirements for oral anticoagulants in thromboembolic events are influenced by promoter polymorphism in the VKORC1 gene. However, limited data are available on the influence of the polymorphism in various Indian populations. The present study aimed at determining the relationship between the VKORC1-1639 G>A genotypes and maintenance doses of oral anticoagulants for therapeutically stable INR values in patients taking Acitrom after valve replacement surgery. MATERIALS AND METHODS Fifty patients from the northern Indian region were genotyped for VKORC1-1639 G>A by polymerase chain reaction and restriction fragment length polymorphism. Means of the weight-normalized daily Acitrom dose were calculated for every patient. RESULTS AND DISCUSSION The VKORC1 1639G>A minor allele frequency in the study population (n = 50) was found to be 22%. The patients with a wild type genotype required the maximum drug dose as suggested for full functionality of the enzyme. Heterozygous patients were found to have an intermediate drug dose and the patients with a variant homozygous genotype had the minimum maintenance drug dose requirement. These findings are in concurrence with the effect of the promoter polymorphism on vitamin K epoxide reductase activity.1639G>A minor allele frequency in the study population (n = 50) was found to be 22%.
