Preterm infants must develop oral feeding skills before successfully transitioning to home. Pacifier-activated devices playing selected music can improve nonnutritive sucking in preterm infants. A mother’s voice is a positive auditory stimulus for infants.

A brief intervention with a pacifier-activated music player using mother’s voice can decrease tube feeding duration without adverse effects on stress or growth. Operant conditioning with positive reinforcement is an effective developmental strategy to improve preterm infants’ feeding skills. (Read the full article)

Diarrhea still remains as a significant cause of morbidity and mortality. Intervention to reduce this risk are needed. Evidence on the effect of Lactobacillus reuteri DSM 17938 to prevent diarrhea in children is scarce.

In healthy children attending day care centers, daily administration of L reuteri DSM 17938 had a significant effect in reducing episodes and duration of diarrhea and respiratory tract infections, with consequent cost saving for the community. (Read the full article)

Although expert consensus and previous literature document the importance of early feeding and activity behaviors and practices in preventing obesity and the risks of early rapid weight gain, few studies have rigorously assessed obesity-related behaviors by caregivers of infants.

This study demonstrates the high prevalence of behaviors thought to increase risk for obesity in a diverse, large sample of parent/2-month-old dyads and finds that many behaviors vary by race and ethnicity, suggesting the potential for culturally tailored interventions. (Read the full article)

Diabetic ketoacidosis (DKA) is a life-threatening condition and often the presenting symptom of newly diagnosed type 1 or type 2 diabetes in youth. SEARCH previously reported that the prevalence of DKA at diagnosis was 25.5% in 2002–2003.

DKA in youth with type 1 diabetes remains a problem, with almost one-third presenting with DKA. Among youth with type 2 diabetes, DKA was less common and decreased by ~10% per year, suggesting improved detection or earlier diagnosis. (Read the full article)

Resistance exercise is known to have a robust effect on glycemic control and cardiometabolic health among children and adolescents, even in the absence of weight loss.

Normalized strength capacity is associated with lower cardiometabolic risk clustering in boys and girls, even after adjustment for cardiorespiratory fitness, level of physical activity, and BMI. (Read the full article)

Children receive only half of recommended health care; disadvantaged children have higher risk of unmet needs. Practice coaching combined with quality improvement using rapid-cycle feedback has potential to help practices meet quality standards and improve pediatric health care delivery.

The Practice-tailored Facilitation Intervention led to large and sustained improvements in preventive service delivery, including substantial numbers of disadvantaged children, and in multiple simultaneous health care domains. Practice-tailored facilitation holds promise as a method to advance pediatric preventive care delivery. (Read the full article)

Animal studies document dose-dependent and duration-of-therapy-dependent fluoroquinolone cartilage toxicity in weight-bearing joints. Preliminary pediatric data collected after fluoroquinolone treatment and up to 1 year posttreatment in blinded and unblinded studies suggest the possibility of cartilage toxicity in children.

These are the first prospectively collected data on fluoroquinolone musculoskeletal safety collected posttherapy from randomized, comparative studies of respiratory tract infections and analyzed at 5 years. Long-term musculoskeletal adverse events occurred with equal frequency in both levofloxacin and comparator groups. (Read the full article)

Prophylactic indomethacin in extremely low birth weight infants decreases severe intraventricular hemorrhage and patent ductus arteriosus but it is unknown whether concurrent enteral feeding and prophylactic indomethacin is associated with increased risk of spontaneous intestinal perforation.

The combination of prophylactic indomethacin and enteral feeding during the first 3 days after birth does not increase the risk of spontaneous intestinal perforation. (Read the full article)

The population of youth with chronic medical conditions is growing and many attend college. Yet we know little about US colleges’ capacity to identify and care for these youth, nor how transition guidelines and financing models should incorporate college health.

This is the first study to find that although many colleges can provide some clinical care for youth with chronic conditions, few colleges have systems to identify and track these students, elucidating gaps that pediatricians and institutions need to address. (Read the full article)

Previous studies have demonstrated racial and ethnic differences in glycemic control even after adjustment for variables such as insulin dosage, diabetes duration, and socioeconomic status. It is controversial whether genetic, physiologic, cultural, socioeconomic, and/or provider-related factors underlie these disparities.

This study in a large, racially/ethnically diverse sample of children with type 1 diabetes demonstrates that racial disparities in insulin treatment methods and diabetes outcomes remain even after adjustment for socioeconomic status. (Read the full article)

No cognitive or neuroanatomical effects were detected at 8 years. (Read the full article)

Previous studies have shown racial differences in invasive pneumococcal disease (IPD) rates. Recent studies demonstrated a national decline in IPD rates after 13-valent pneumococcal conjugate vaccine (PCV13) introduction. The impact of PCV13 on racial and regional differences in IPD rates among Tennessee children is unknown.

After introduction of PCV13, pediatric IPD rates, including disease due to antibiotic-resistant strains, declined substantially. Racial and regional differences in IPD rates were no longer significant. Our study illustrates the impact of PCV13 and the importance of continued IPD surveillance. (Read the full article)

Dans de nombreux pays, le pétrole suscite des débats controversés sur son rôle de moteur de changements économiques, sociaux et géopolitiques. Depuis quelques années, les réflexions sur la question du pétrole ont démontré une corrélation négative entre son exploitation, le développement socioéconomique, la gouvernance et le regain des conflits dans les pays producteurs.

Los conflictos en los países pequeños suelen agravarse debido a la indiferencia internacional. Sin embargo, en el caso de la República Centroafricana (RCA), el problema es ligeramente distinto. Hay una importante presencia internacional en este Estado, pero los actores principales han decidido mantenerse al margen y esperar en vez de intervenir activamente en la crisis.

Carbapenems are currently the preferred agents for the treatment of serious Acinetobacter infections. However, whether cefepime/cefpirome can be used to treat Acinetobacter bloodstream infection (BSI) if it is active against the causative pathogens is not clear. This study aimed to compare the efficacy of cefepime/cefpirome and carbapenem monotherapy in patients with Acinetobacter BSI. The population included 360 patients with monomicrobial Acinetobacter BSI receiving appropriate antimicrobial therapy admitted to four medical centres in Taiwan in 2012–2017. The predictors of 30-day mortality were determined by Cox regression analysis. The overall 30-day mortality rate in the appropriate antibiotic treatment group was 25.0% (90/360 patients), respectively. The crude 30-day mortality rates for cefepime/cefpirome and carbapenem therapy were 11.5% (7/61 patients) and 26.3% (21/80 patients), respectively. The patients receiving cefepime/cefpirome/carbapenem therapy were infected by Acinetobacter nosocomialis (51.8%), A. baumannii (18.4%) and A. pittii (12.1%). After adjusting for age, Sequential Organ Failure Assessment (SOFA) score, invasive procedures, and underlying diseases, cefepime/cefpirome therapy was not independently associated with a higher or lower 30-day mortality compared to the carbapenem therapy. SOFA score (hazard ratio [HR], 1.324; 95% confidence interval [CI], 1.137–1.543; P < 0.001) and neutropenia (HR, 7.060; 95% CI, 1.607–31.019; P = 0.010) were independent risk factors for 30-day mortality of patients receiving cefepime/cefpirome or carbapenem monotherapy. The incidence density of 30-day mortality for cefepime/cefpirome versus carbapenem therapy was 0.40% versus 1.04%. The therapeutic response of cefepime/cefpirome therapy was comparable to that of carbapenems among patients with Acinetobacter BSI receiving appropriate antimicrobial therapy.

QPX7728 is an ultra-broad-spectrum boronic acid beta-lactamase inhibitor that demonstrates inhibition of key serine and metallo beta-lactamases at a nano molar range in biochemical assays with purified enzymes. The broad-spectrum inhibitory activity of QPX7728 observed in biochemical experiments translates into enhancement of the potency of many beta-lactams against strains of target pathogens producing beta-lactamases. The impact of bacterial efflux and permeability on inhibitory potency were determined using isogenic panels of KPC-3 producing isogenic strains of K. pneumoniae and P. aeruginosa and OXA-23-producing strains of A. baumannii with various combinations of efflux and porin mutations. QPX7728 was minimally affected by multi-drug resistance efflux pumps in either Enterobacteriaceae, or in non-fermenters such as P. aeruginosa or A. baumannii. In P. aeruginosa, the potency of QPX7728 was further enhanced when the outer membrane is permeabilized. The potency of QPX7728 in P. aeruginosa is not affected by inactivation of the carbapenem porin OprD. While changes in OmpK36 (but not OmpK35) reduced the potency of QPX7728 (8-16-fold), QPX7728 (4 μg/ml) nevertheless completely reversed KPC-mediated meropenem resistance in strains with porin mutations, consistent with a lesser effect of these mutations on the potency of QPX7728 compared to other agents. The ultra-broad-spectrum beta-lactamase inhibition profile combined with enhancement of the activity of multiple beta-lactam antibiotics with varying sensitivity to the intrinsic resistance mechanisms of efflux and permeability indicate QPX7728 is a useful inhibitor for use with multiple beta-lactam antibiotics.

Probiotics might provide an alternative approach for the control of oral candidiasis. However, studies on the antifungal activity of probiotics in the oral cavity are based on the consumption of yogurt or other dietary products, and there is a necessary to use appropriate biomaterials and specific strains to obtain probiotic formulations targeting local oral administration. In this study, we impregnated gellan gum, a natural biopolymer used as a food-additive, with a probiotic and investigated its antifungal activity against Candida albicans. Lactobacillus paracasei 28.4, a strain recently isolated from the oral cavity of a caries-free individual, was incorporated in several concentrations of gellan gum (0.6% to 1%). All tested concentrations could incorporate L. paracasei cells while maintaining bacterial viability. Probiotic/gellan formulations were stable for 7 days when stored at room temperature or 4°C. Long-term storage of bacteria-impregnated gellan gum was achieved when L. paracasei 28.4 was lyophilized. The probiotic/gellan formulations provided a release of L. paracasei cells over 24 hours that was sufficient to inhibit the growth of C. albicans with effects dependent on the cell concentrations incorporated into gellan gum. The probiotic/gellan formulations also had inhibitory activity against Candida spp. biofilms by reducing the number of Candida spp. cells (p < 0.0001), decreasing the total biomass (p = 0.0003), and impairing hyphae formation (p = 0.0002), compared to the control group which received no treatment. Interestingly, probiotic formulation of 1% w/v gellan gum provided an oral colonization of L. paracasei in mice with approximately 6 log of CFU/mL after 10 days. This formulation inhibited the C. albicans growth (p < 0.0001), prevented the development of candidiasis lesions (p = 0.0013), and suppressed inflammation (p = 0.0006) when compared to the mice not treated in the microscopic analysis of the tongue dorsum. These results indicate that gellan gum is a promising biomaterial and can be used as a carrier system to promote oral colonization for probiotics that prevent oral candidiasis.

Gepotidacin, a triazaacenaphthylene bacterial type II topoisomerase inhibitor, is in development for treatment of uncomplicated urinary tract infection (uUTI). This Phase 2a study in female participants with uUTI evaluated the pharmacokinetics (primary objective), safety, and exploratory efficacy of gepotidacin. Eligible participants (N = 22) were confined to the clinic at baseline, received oral gepotidacin 1,500 mg twice daily for 5 days (on-therapy; Days 1 to 5), and returned to the clinic for test-of-cure (Days 10 to 13) and follow-up (Day 28±3). Pharmacokinetic, safety, clinical, and microbiological assessments were performed. Maximum plasma concentrations were observed approximately 1.5 to 2 hours postdose. Steady state was attained by Day 3. Urinary exposure over the dosing interval increased from 3,742 μg.h/ml (Day 1) to 5,973 μg.h/ml (Day 4), with trough concentrations of 322 to 352 μg/ml from Day 3 onward. Gepotidacin had an acceptable safety-risk profile with no treatment-limiting adverse events and no clinically relevant safety trends. Clinical success was achieved in 19 (86%) and 18 (82%) of 22 participants at test-of-cure and follow-up, respectively. Eight participants had a qualifying baseline uropathogen (growth; ≥10⁵ CFU/ml). A therapeutic (combined clinical and microbiological [no growth; <10³ CFU/ml]) successful response was achieved in 6 (75%) and 5 (63%) of 8 participants at test-of-cure and follow-up, respectively. Plasma area under the free-drug concentration-time curve over 24 hours at steady state divided by the MIC (fAUC_0-24/MIC) and urine AUC_0-24/MIC ranged from 6.99 to 90.5 and 1,292 to 121,698, respectively. Further evaluation of gepotidacin in uUTI is warranted. (NCT03568942)

Pharmacokinetic changes are often seen in patients with severe infections. Administration by continuous infusion has been suggested to optimize antibiotic exposure and pharmacokinetic/pharmacodynamic (PK/PD) target attainment for β-lactams. In an observational study, unbound piperacillin concentrations (n=196) were assessed in 78 critically ill patients following continuous infusion of piperacillin/tazobactam (ratio 8:1). The initial dose of 8, 12 or 16 g (piperacillin component) was determined by individual creatinine clearance (CRCL). Piperacillin concentrations were compared to the EUCAST clinical breakpoint MIC for Pseudomonas aeruginosa (16 mg/L), and the following PK/PD targets were evaluated: 100% fT>1xMIC and 100% fT>4xMIC. A population pharmacokinetic model was developed using NONMEM 7.4.3 consisting of a one-compartment disposition model with linear elimination separated into non-renal and renal (linearly increasing with patient CRCL) clearances. Target attainment was predicted and visualized for all individuals based on the utilized CRCL dosing algorithm. The target of 100% fT>1xMIC was achieved for all patients based on the administered dose, but few patients achieved the target of 100% fT>4xMIC. Probability of target attainment for a simulated cohort of patients showed, that increasing the daily dose by 4 g increments (piperacillin component) did not result in substantially improved target attainment for the 100% fT>4xMIC target. To conclude, in patients with high CRCL combined with high-MIC bacterial infections, even a CI regimen with a daily dose of 24 g may be insufficient to achieve therapeutic concentrations.

Two non-amidated host defence peptides named Pin2[G] and FA1 were evaluated against three types of pathogenic bacteria; two isolated from diabetic foot ulcer patients, Staphylococcus aureus UPD13 and Pseudomonas aeruginosa UPD3, and another from a commercial collection, Salmonella enterica serovar Typhimurium (ATCC 14028). In vitro experiments showed that the antimicrobial performance of the synthetic peptides, Pin2[G] and FA1, was modest, although FA1 was more effective than Pin2[G]. In contrast Pin2[G] had superior in vivo anti-infective activity to FA1 in rabbit wound infections by the diabetic foot ulcer pathogens S. aureus UPD13 and P. aeruginosa UPD3. Indeed, Pin2[G] reduced bacterial colony counts of both S. aureus UPD13 and P. aeruginosa UPD3 by >100,000-fold after 48-72 h on skin wounds of infected rabbits, while in similar infected wounds, FA1 had no major effects at 72-96 h of treatment. Ceftriaxone was equally effective vs. Pseudomonas but less effective vs. S. aureus infections. Additionally, the two peptides were evaluated in mice against intragastrically inoculated S. enterica ser. Typhimurium (ATCC 14028). Only Pin2[G], at 0.56 mg/kg, was effective in reducing systemic (liver) infection by >67-fold, equivalent to the effect of treatment with levofloxacin. Pin2[G] showed superior immunomodulatory activity in increasing chemokine production by a human bronchial cell line and suppressing poly(IC)-induced pro-inflammatory IL6 production. These data showed that the in vitro antimicrobial activity of these peptides was not correlated with their in vivo anti-infective activity, and suggest that other factors such as immunomodulatory activity were more important.

Treatment of exacerbations of chronic Pseudomonas aeruginosa infections in patients with cystic fibrosis (CF) is highly challenging due to hypermutability, biofilm formation and an increased risk of resistance emergence. We evaluated the impact of ciprofloxacin and meropenem as monotherapy and in combination in the dynamic in vitro CDC biofilm reactor (CBR). Two hypermutable P. aeruginosa strains, PAOmutS (MIC_{ciprofloxacin} 0.25 mg/L, MIC_meropenem 2 mg/L) and CW44 (MIC_{ciprofloxacin} 0.5 mg/L, MIC_meropenem 4 mg/L), were investigated for 120h. Concentration-time profiles achievable in epithelial lining fluid (ELF) following FDA-approved doses were simulated in the CBR. Treatments were ciprofloxacin 0.4g every 8h as 1h-infusions (80% ELF penetration), meropenem 6 g/day as continuous infusion (CI; 30% and 60% ELF penetration) and their combinations. Counts of total and less-susceptible planktonic and biofilm bacteria and MICs were determined. Antibiotic concentrations were quantified by UHPLC-PDA. For both strains, all monotherapies failed with substantial regrowth and resistance of planktonic (≥8log₁₀ CFU/mL) and biofilm (>8log₁₀ CFU/cm²) bacteria at 120h (MIC_{ciprofloxacin} up to 8 mg/L, MIC_meropenem up to 64 mg/L). Both combination treatments demonstrated synergistic bacterial killing of planktonic and biofilm bacteria of both strains from ~48h onwards and suppressed regrowth to ≤4log₁₀ CFU/mL and ≤6log₁₀ CFU/cm² at 120h. Overall, both combination treatments suppressed amplification of resistance of planktonic bacteria for both strains, and biofilm bacteria for CW44. The combination with meropenem at 60% ELF penetration also suppressed amplification of resistance of biofilm bacteria for PAOmutS. Thus, combination treatment demonstrated synergistic bacterial killing and resistance suppression against difficult-to-treat hypermutable P. aeruginosa strains.
