Neonatal infections are associated with high morbidity and mortality rates. Optimal treatment of these infections requires knowledge of neonatal pharmacology and integration of neonatal developmental pharmacokinetics of antimicrobial drugs in the design of dosing regimens for use with different gestational and postnatal ages. Population pharmacokinetic (PK) and pharmacodynamic (PD) models are used to personalize the use of these drugs in these fragile patients. The final step to further minimize variability in an individual patient is therapeutic drug monitoring (TDM), where the same population PK/PD models are used in concert with optimally drawn blood samples to further fine-tune therapy. The purpose of this manuscript is to describe the present status and future role of model-based precision dosing and TDM of antimicrobial drugs in neonates.

PubMed was searched for clinical trials or clinical studies of TDM in neonates.

A total of 447 papers were retrieved, of which 19 were concerned with antimicrobial drugs. Two papers (one aminoglycoside and one vancomycin) addressed the effects of TDM in neonates. We found that, in addition to aminoglycosides and vancomycin, TDM also plays a role in beta-lactam antibiotics and antifungal drugs.

There is a growing awareness that, in addition to aminoglycosides and vancomycin, the use of beta-lactam antibiotics, such as amoxicillin and meropenem, and other classes of antimicrobial drugs, such as antifungal drugs, may benefit from TDM.

To evaluate the outcomes of delay in care secondary to the coronavirus (COVID-19) pandemic in patients requiring intravitreal anti-vascular endothelial growth factor (VEGF) therapy.

A retrospective review was performed, and subjects were divided into 1) a Study Group of patients who experienced a treatment delay ≥ 6 weeks from intended follow up during the COVID-19 pandemic and resumed treatment with ≥ 2 anti-VEGF injections over 6 months following treatment delay, and 2) a Control Group of patients who received regular care throughout the COVID-19 pandemic.

There were 234 subjects analyzed. The mean treatment delay from intended follow up in the Study Group was 11.8 (+/- 4.0) weeks. Visual acuity and central macular thickness (CMT) worsened from baseline to 6 months after resuming anti-VEGF therapy in the Study Group (p<0.0001 and p=0.001, respectively). Visual acuity and CMT were better in the Control Group compared to the Study Group at the end of the 6-month study period (p<0.0001 for both).

Treatment delay in subjects undergoing anti-VEGF therapy for retina disease during the COVID-19 pandemic had worse visual and anatomic outcomes despite reinitiating treatment over 6 months compared to a control group, suggesting irreversibility and permanence of outcomes.

To describe uveitis cases following the BNT162b2 mRNA SARS-CoV-2 vaccination.

This is a multicenter, retrospective study. Vaccine related-uveitisdiagnosis was supported by the classification of the World Health Organization Adverse Drug Terminology and the Naranjo criteria.

Twenty-one patients (23 eyes) with a mean age of 51.3 years (23-78 years) were included. Eight /21 patients had a known history of uveitis, the median time from previous to current attack was 1 year (0.5-15 years). There were 21 anterior uveitis cases, two with bilateral inflammation. Eight cases occurred post first and 13 post second vaccination. All but 3 presented as mild to moderate disease. Two patients developed multiple evanescent white dot syndrome (MEWDS) following the second vaccination. Mean time between vaccination to uveitis onset was 7.5 ± 7.3 days (1-30 days). At final follow-up, complete resolution was achieved in all but two eyes, which showed significant improvement. One case of severe anterior uveitis developed vitritis and macular edema following second vaccination, which completely resolved following an intravitreal dexamethasone injection.

Uveitis may develop after the administration of the BNT162b2 mRNA vaccine. The most common complication was mild to moderate anterior uveitis, while less frequent, MEWDS can also occur.

To define the effect of age-related macular degeneration (AMD) and diabetic retinopathy (DR) on the ocular thermographic profile.

This retrospective cross-sectional study included subjects diagnosed with DR or AMD between January and April 2019. Individuals without ocular disease served as controls. Thermal imaging camera was used for ocular surface temperature (OST) acquisition. The mean temperatures of the medial cantus, lateral cantus, and cornea were calculated.

Thermographic images were obtained from 133 subjects (260 eyes, 97 DR, 163 AMD) and 48 controls (55 eyes). OST was higher among AMD patients and lowest among DR patients (P < 0.001). A subgroup analysis revealed that eyes with diabetic macular edema (DME) had significantly higher OSTs than DR eyes without DME. Moreover, the OST in eyes with DME was similar to the measurements of the AMD group. There were no differences in OSTs between neovascular and non-neovascular AMD eyes.

To introduce cases of intraocular lens (IOL) malposition after sutureless intrascleral fixation.

We retrospectively analyzed the medical records of patients who underwent sutureless intrascleral fixation. Cases with postoperative IOL requiring reoperation were analyzed further.

Of the 48 eyes that underwent sutureless intrascleral fixation of their IOL, seven eyes had postoperative IOL malposition and underwent reoperation (14.6%). There was no difference in the clinical results between the intravitreal (33 eyes) and intracameral (15 eyes) techniques, but IOL malposition requiring reoperation was more frequent in the latter (two cases [6.1%] vs. five cases [33.3%], p=0.024). In the seven eyes that required reoperation, visual acuity before reoperation was 0.9±0.6 logMAR (20/159), while astigmatism was -4.8±3.2 diopters. The visual acuity and cylindrical error improved to 0.1±0.2 logMAR (20/25) and -2.4±2.3 diopters, respectively, at 6 months after the secondary operation.

In 14.6% of the patients who underwent sutureless intrascleral fixation of the IOL, IOL malposition developed and reoperation was performed. With the intravitreal technique, which uses a wider space than the intracameral technique, the frequency of postoperative IOL malposition could be reduced.

Nearly half of pediatric homicides under age 5 are attributable to child abuse. Parents are most commonly the perpetrators, but less is known about incidents involving biological vs. surrogate parents. We sought to evaluate the characteristics of fatal child abuse involving biological and surrogate parents using the Georgia National Violent Death Reporting System (NVDRS), which we believe may differ in demographics and incident characteristics.

This database was used to examine all homicides of children under age 18 from 2011-2017. Demographics and incident characteristics were analyzed using existing NVDRS variables and incident narratives. Chi-squared and nonparametric tests were used to compare fatal child abuse incidents involving biological and surrogate parents (e.g., adoptive, foster, step-parents, intimate partners of biological parent).

There were 452 pediatric homicides and 219 cases of fatal child abuse. Of all cases of fatal child abuse, 60% involved biological and 29% involved surrogate parents. Compared to children killed by biological parents, children killed by surrogate parents were older (4 vs. 3 years old), more often male (71% vs. 51%), more likely to survive the initial injury and present to the ED before death (96% vs. 69%), and less likely to have a medical comorbidity (2% vs 11%), all p < 0.05. Surrogate parents were more likely to be male (90% vs. 48%) and use a firearm (20% vs. 13%) to inflict the injury, both p < 0.05. The race/ethnicity of the child was not associated with the parent's relationship.

Child abuse accounts for half of all pediatric homicides. Parents are the most common perpetrators of fatal child abuse, but surrogate parent perpetrators are almost exclusively male and more likely to use firearms. Most children have a history of abuse, leaving an opportunity to intervene on potentially preventable deaths if abuse is identified in a timely fashion.

While the concept of a "target trial"- optimising the quality of observational studies by attempting to emulate the ideal world conditions of a randomized controlled trial- was first expounded over a decade ago, the take up of this concept in the design and analysis of trials in trauma is lacking. The target trial approach avoids common errors in observational research in order to increase its scientific validity as well as potentially enable causal questions to be answered without the expense and intricacies of a randomized controlled trial (RCT). This review article briefly introduces the reader to the concepts and utility of a "target trial" approach before providing demonstrations of its application in the subject area of chest trauma.

Four articles published in the last five years- two case control and two cohort studies are chosen and considered in terms of their causal question; study population; inclusion and exclusion criteria; designation of time zero; clarity of the follow-up period; study outcomes; methods to minimise confounding; results; overall issues regarding study time; and the presence of avoidable errors such as introduction of immortal time bias or information bias.

Two of the studies had an unclear causal question; none of the studies designated a time zero; the follow-up period was unclear for all but one of the studies; and one study had a serious issue with information bias resulting from differential misclassification.

Failure to emulate a "target trial" framework may lead to serious methodologic issues in observational research. Expansion of the awareness of this approach in trauma literature will improve the quality of our observational research and potentially translate into significant benefits for our patients.
