Editorial: Congenital and perinatal infections: How to prevent sequelaes in neonates and children
The current severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pandemic has overwhelmingly absorbed attention and health resources for 2 years, allowing us to reflect that infections are a permanent health and social problem, causing morbidity and mortality. They require organization, important prevention measures, and containment. This is particularly true in the neonatal age, where infections remain a complex problem with serious consequences
Recovery of distal coronary flow reserve in LAD and LCx after Y-Graft intervention assessed by transthoracic echocardiography
<p>Abstract</p> <p>Background</p> <p>Y- graft (Y-G) is a graft formed by the Left Internal Mammary Artery (LIMA) connected to the Left Anterior Descending Artery (LAD) and by a free Right Internal Mammary Artery (RIMA) connected to LIMA and to a Marginal artery of Left Circumflex Artery (LCx). Aim of the work was to study the flow of this graft during a six months follow-up to assess whether the graft was able to meet the request of all the left coronary circulation, and to assess whether it could be done by evaluation of coronary flow reserve (CFR).</p> <p>Methods</p> <p>In 13 consecutive patients submitted to Y-G (13 men), CFR was measured in distal LAD and in distal LCx from 1 week after , every two months, up to six months after operation (a total of 8 tests for each patient) by means of transthoracic echocardiography (TTE) and Adenosine infusion (140 mcg/kg/min for 3-6 min). A Sequoia 256, Acuson-Siemens, was used. Contrast was used when necessary (Levovist 300 mg/ml solution at a rate of 0,5-1 ml/min). Max coronary flow diastolic velocity post-/pre-test â„2 was considered normal CFR.</p> <p>Results</p> <p>Coronary arteriography revealed patency of both branches of Y-G after six months. Accuracy of TTE was 100% for LAD and 85% for LCx. Feasibility was 100% for LAD and 85% for LCx. CFR improved from baseline in LAD (2.21 ± 0.5 to 2.6 ± 0.5, p = 0.03) and in LCx (1.7 ± 1 to 2.12 ± 1, p = 0.05). CFR was under normal at baseline in 30% of patients <it>vs </it>8% after six months in LAD (p = 0.027), and in 69% of patients <it>vs </it>30% after six months in LCx (p = 0.066).</p> <p>Conclusion</p> <p>CFR in Y-G is sometimes reduced in both left territories postoperatively but it improves at six months follow-up. A follow-up can be done non-invasively by TTE and CFR evaluation.</p

Meropenem vs standard of care for treatment of neonatal late onset sepsis (NeoMero1): A randomised controlled trial.
BACKGROUND: The early use of broad-spectrum antibiotics remains the cornerstone for the treatment of neonatal late onset sepsis (LOS). However, which antibiotics should be used is still debatable, as relevant studies were conducted more than 20 years ago, recruited in single centres or countries, evaluated antibiotics not in clinical use anymore and had variable inclusion/exclusion criteria and outcome measures. Moreover, antibiotic-resistant bacteria have become a major problem in many countries worldwide. We hypothesized that efficacy of meropenem as a broad-spectrum antibiotic is superior to standard of care regimens (SOC) in empiric treatment of LOS and aimed to compare meropenem to SOC in infants aged 44 weeks meeting the Goldstein criteria of sepsis, were randomized in a 1:1 ratio to receive meropenem or one of the two SOC regimens (ampicillin+gentamicin or cefotaxime+gentamicin) chosen by each site prior to the start of the study for 8-14 days. The primary outcome was treatment success (survival, no modification of allocated therapy, resolution/improvement of clinical and laboratory markers, no need of additional antibiotics and presumed/confirmed eradication of pathogens) at test-of-cure visit (TOC) in full analysis set. Stool samples were tested at baseline and Day 28 for meropenem-resistant Gram-negative organisms (CRGNO). The primary analysis was performed in all randomised patients and in patients with culture confirmed LOS. Proportions of participants with successful outcome were compared by using a logistic regression model adjusted for the stratification factors. From September 3, 2012 to November 30th 2014, total of 136 patients (instead of planned 275) in each arm were randomized; 140 (52%) were culture positive. Successful outcome at TOC was achieved in 44/136 (32%) in the meropenem arm vs. 31/135 (23%) in the SOC arm (p = 0.087). The respective numbers in patients with positive cultures were 17/63 (27%) vs. 10/77 (13%) (p = 0.022). The main reason of failure was modification of allocated therapy. Treatment emergent adverse events occurred in 72% and serious adverse events in 17% of patients, the Day 28 mortality was 6%. Cumulative acquisition of CRGNO by Day 28 occurred in 4% of patients in the meropenem and 12% in the SOC arm (p = 0.052). CONCLUSIONS: Within this study population, we found no evidence that meropenem was superior to SOC in terms of success at TOC, short term hearing disturbances, safety or mortality were similar in both treatment arms but the study was underpowered to detect the planned effect. Meropenem treatment did not select for colonization with CRGNOs. We suggest that meropenem as broad-spectrum antibiotic should be reserved for neonates who are more likely to have Gram-negative LOS, especially in NICUs where microorganisms producing extended spectrum- and AmpC type beta-lactamases are circulating
Lessons from SARS-CoV-2 Pandemics: How Restrictive Measures Impacted the Trend of Respiratory Infections in Neonates and Infants up to Three Months of Age
(1) Background: Massive social efforts to prevent the spread of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic have affected the epidemiological features of respiratory infections. (2) Methods: The study aims to describe the trend of hospitalizations for bronchiolitis among newborns and infants up to three months of life in Rome (Italy), in the pre-COVID-19 era and during the pandemic. (3) Results: We observed a marked decrease in the number of neonates and infants with bronchiolitis after national lockdowns in 2020 and the first months of 2021 and a similar trend in the number of bronchiolitis caused by respiratory syncytial virus (RSV). RSV was the leading pathogen responsible for bronchiolitis before the national lockdown in March 2020 (70.0% of cases), while Rhinovirus was the leading pathogen responsible for bronchiolitis (62.5%) during the pandemic while strict restrictions were ongoing. As Italy approached the COVID-19 vaccination target, the national government lifted some COVID-19-related restrictions. A surprising rebound of bronchiolitis (particularly cases caused by RSV) was observed in October 2021. (4) Conclusions: In this study, we describe for the first time the fluctuations over time of RSV bronchiolitis among newborns and young infants in Italy in relation to the restrictive measures containing the spread of the COVID-19 pandemic. Our results are in line with other countries' reports
Intersociety Position Statement on the Prevention of Ophthalmia Neonatorum in Italy
There is currently no worldwide agreement on the real need to administer conjunctival antibiotics to neonates at birth to prevent neonatal conjunctivitis (usually defined as ophthalmia neonatorum) by Chlamydia trachomatis and Neisseria gonorrhoeae. Therefore, there is wide variability in antibiotic administration, conditioned mainly by the social and health context. In Italy, a law enacted in 1940 required doctors and midwives to administer ophthalmic prophylaxis with 2% silver nitrate to all newborns at birth. This law was repealed in 1975 and since then there has been no clear guidance on the use of ophthalmia neonatorum prophylaxis at birth. Since neonatal conjunctivitis caused by C. trachomatis and N. gonorrhoeae is not reported, we carried out a nationwide survey of 1,041,384 neonates across all Italian birth centers to evaluate the incidence of ophthalmia neonatorum and the current practice of prophylaxis. After analyzing the results, we formulated an intersociety position statement on the prevention of ophthalmia neonatorum to update and standardize this prevention strategy in Italy

DMAIC Approach for the Reduction of Healthcare-Associated Infections in the Neonatal Intensive Care Unit of the University Hospital of Naples âFederico IIâ
Improvements in the obstetrical and neonatal management have allowed children to survive. These enhancements have showed, anyway, a general increased incidence of healthcare-associated infections, one of the most influent causes of morbidity and mortality in neonatal intensive care units. The aim of this paper is to suggest corrective measures to reduce sentinel germs colonization and identify the relationships between bacteria colonization with the number of procedures and the length of hospital stay. The Lean Six Sigma methodology was used to tackle this issue using a tailored Define, Measure, Analyze, Improve, and Control problem-solving strategy. An increased number of procedures and an extended length of hospital stay demonstrated a statistically significant influence on newbornsâ possibility to be infected by sentinel germs. These findings could guide the clinical staff to improve the management of neonates in neonatal intensive care units reducing the number of infected patients, their length of hospital stay and the costs for the hospital. © 2021, Springer Nature Switzerland AG
Antibiotic prophylaxis for ophthalmia neonatorum in Italy: results from a national survey and the Italian intersociety new position statements
Background: Ophthalmia neonatorum is an acute conjunctivitis that occurs in newborns within the first month of life. The most serious infections are due to Chlamydia trachomatis and Neisseria gonorrhoeae, that may cause permanent damages. The use of ophthalmic prophylaxis varies widely around the world, according to the different health and socio-economic contexts. To date in Italy there is no a clear legislation regarding ophthalmia neonatorum prophylaxis at birth. Methods: We invited all birth centers in Italy to carry out a retrospective survey relating the last three years. We collected data regarding demographics of neonates, drugs used for ophthalmic prophylaxis and results of the screening of pregnant women for Chlamydia trachomatis and Neisseria gonorrhoeae vaginal infections. Results: Among 419 birth centers, 302 (72,1%) responded to the survey. Overall 1041384 neonates, 82,3% of those born in the three years considered, received ophthalmic prophylaxis. Only 4,585 (0,4%) of them received one of the drugs recommended by the WHO. The Centers that participated to the survey reported 12 episodes of Chlamydial conjunctivitis and no Gonococcal infection in the three years. Only 38% of the Centers performed vaginal swabs to pregnant women: 2,6% screened only for Neisseria, 9,6% only for Chlamydia and 25,8% for both germs. Conclusions: The data obtained from the survey showed a low incidence of neonatal conjunctivitis due to either Neisseria gonorrhoeae or Chlamydia trachomatis in Italy. Due to the lack of legislation regulating the prophylaxis of ophthalmia neonatorum in newborns, the Italian Society of Neonatology, the Italian Society of Obstetrics and Gynecology and the Italian Society of Perinatal Medicine have recently issued new recommendations on this topic
Surgical Antimicrobial Prophylaxis in Abdominal Surgery for Neonates and Paediatrics: A RAND/UCLA Appropriateness Method Consensus Study
Surgical site infections (SSIs), i.e., surgery-related infections that occur within 30 days after surgery without an implant and within one year if an implant is placed, complicate surgical procedures in up to 10% of cases, but an underestimation of the data is possible since about 50% of SSIs occur after the hospital discharge. Gastrointestinal surgical procedures are among the surgical procedures with the highest risk of SSIs, especially when colon surgery is considered. Data that were collected from children seem to indicate that the risk of SSIs can be higher than in adults. This consensus document describes the use of preoperative antibiotic prophylaxis in neonates and children that are undergoing abdominal surgery and has the purpose of providing guidance to healthcare professionals who take care of children to avoid unnecessary and dangerous use of antibiotics in these patients. The following surgical procedures were analyzed: (1) gastrointestinal endoscopy; (2) abdominal surgery with a laparoscopic or laparotomy approach; (3) small bowel surgery; (4) appendectomy; (5) abdominal wall defect correction interventions; (6) ileo-colic perforation; (7) colorectal procedures; (8) biliary tract procedures; and (9) surgery on the liver or pancreas. Thanks to the multidisciplinary contribution of experts belonging to the most important Italian scientific societies that take care of neonates and children, this document presents an invaluable reference tool for perioperative antibiotic prophylaxis in the paediatric and neonatal populations
