The healthy term, and particularly the premature infant, is born with a very low glomerular filtration rate (GFR), controlled by a delicate balance of intrarenal vasoconstrictor and vasodilator forces. Vasoactive disturbances can easily further reduce the already low GFR. The newborn infant is thus prone to develop vasomotor nephropathy (VMNP) or acute renal failure (ARF). The main causes for ARF at this young age are prerenal mechanisms, and include hypotension, hypovolemia, hypoxemia perinatal asphyxia, and neonatal septicemia. Other causes include the administration of angiotensin converting enzyme inhibitors, indomethacin and tolazoline. The most-important factors governing the ultimate renal prognosis are the severity of the underlying disorder, the rapidity of an accurate diagnosis, prompt treatment, and avoidance of severe iatrogenic complications. The immediate treatment is of particular importance in VMNP, i.e., prerenal ischemic ARF, and consists of correcting abnormalities in fluid homeostasis and reduction of the complications of the acute azotemic state (uremia, hyperkalemia, acidosis, and hypertension). In severe and prolonged (established) ARF, temporary dialysis therapy may be indicated. Prerenal ARF with oliguria or anuria warrants immediate volume resuscitation. Special attention should be given to infants with congestive heart failure (CHF). The sick neonate with persistent oliguria and CHF should be treated with intravenous dopamine. Furosemide (FM) is the second line of therapy for babies with indomethacin-induced ARF. In most other conditions, the therapeutic effect of FM is limited to a transient increase in urine flow, without improving basic renal function. The special conditions of the maturing kidney have to be appreciated in order to protect babies from undue renal injury. With the increasing knowledge of the mechanisms governing the development of ARF, progress has been made in the development of new treatment modalities. For example theophylline, calcium antagonists, ATP-MgCl2, thyroxine, and a variety of cytokines may in the near future be used to prevent or ameliorate VMNP and/or recently established ARF. With a combination of time-honored and new therapeutic strategies, there may well be a brighter future for neonates with vasomotor, prerenal, ischemic ARF.

The high rate of OW and obesity (31.8%) emphasize the need for developing further strategies to prevent and treat excess fat accumulation in T1D.

OBJECTIVE To analyze whether the coronavirus disease 2019 (COVID-19) pandemic increased the number of cases or impacted seasonality of new-onset type 1 diabetes (T1D) in large pediatric diabetes centers globally. RESEARCH DESIGN AND METHODS We analyzed data on 17,280 cases of T1D diagnosed during 2018–2021 from 92 worldwide centers participating in the SWEET registry using hierarchic linear regression models. RESULTS The average number of new-onset T1D cases per center adjusted for the total number of patients treated at the center per year and stratified by age-groups increased from 11.2 (95% CI 10.1–12.2) in 2018 to 21.7 (20.6–22.8) in 2021 for the youngest age-group, <6 years; from 13.1 (12.2–14.0) in 2018 to 26.7 (25.7–27.7) in 2021 for children ages 6 to <12 years; and from 12.2 (11.5–12.9) to 24.7 (24.0–25.5) for adolescents ages 12–18 years (all P < 0.001). These increases remained within the expected increase with the 95% CI of the regression line. However, in Europe and North America following the lockdown early in 2020, the typical seasonality of more cases during winter season was delayed, with a peak during the summer and autumn months. While the seasonal pattern in Europe returned to prepandemic times in 2021, this was not the case in North America. Compared with 2018–2019 (HbA1c 7.7%), higher average HbA1c levels (2020, 8.1%; 2021, 8.6%; P < 0.001) were present within the first year of T1D during the pandemic. CONCLUSIONS The slope of the rise in pediatric new-onset T1D in SWEET centers remained unchanged during the COVID-19 pandemic, but a change in the seasonality at onset became apparent.

Rates of multidrug resistance and mortality in children with Gram-negative bloodstream infections remain high in our settings. Empiric broad-spectrum antibiotics and combination therapy could be recommended, especially in children with malignant diseases, patients admitted to the PICU, and for cases with septic shock, who have higher mortality risk.
