In almost half [108/227 (48%)] of the studies, ARM was performed awake. The ARM parameters most frequently assessed were the rectoanal inhibitory reflex, which was evaluated in 198/227 studies (87%) and the anal resting pressure [166/227 studies (73%)].

This systematic review has highlighted the vast variation of ARM use within pediatrics and the need to strive toward standardization and use of consensus guidelines. We anticipate this will further advance our understanding of the pathophysiological mechanisms involved in children with defecation disorders.

It is generally accepted that patients who have greater functional capacity are better candidates for lung transplantation. Accurate assessment of physical condition is important in identifying appropriate candidates for transplant. The focus of this study was to determine which measures of pretransplant physical condition correlate with positive post-transplant outcomes in children undergoing lung transplant.

A retrospective chart review was done on 44 patients, ages 5 to 21years. The pretransplant data collected included functional status, 6MWT, ambulatory status, and mechanical support. Post-transplant outcome data included time on the ventilator, days in the ICU, length of hospitalization, and 12-month survival.

Results were analyzed using Fisher exact and Kruskal-Wallis tests. Smad activation Patients with limited ambulation had more days in the ICU compared to the most ambulatory group (P=.043). Patients independent or needing some help with ADL had less time on the ventilator compared to patients needing total help. (P=.014). Patients with 6MWT result greater than 500' had fewer ICU days (P=.044) and marginally better 12-month survival (P=.057). The 12-month survival of children needing invasive ventilatory support pretransplant was not significantly worse than those who did not; however, they required significantly more time on the ventilator (P=.004), days in ICU (P=.013), and longer hospitalization.

This study demonstrated that pretransplant physical condition affects post-transplant outcomes in children. Measures associated with positive post-transplant outcomes were identified and could be beneficial in determining which patients are optimal candidates for lung transplant.

Peak oxygen consumption (pVO
), determined from CPET, provides a valuable indication of PAH severity and patient prognosis. However, CPET is often contraindicated in severe PAH and frequently terminated prior to achievement of a sufficient exercise effort. We sought to determine whether in PAH low-intensity [i.e. freewheeling exercise (FW)] exercise reveals abnormal V
/VCO
and P
CO
responses that are associated with pVO
and serve as indices of PAH risk stratification and mortality.

Retrospective analysis of CPET from 97 PAH patients and 20 age-matched controls was undertaken. FW V
/VCO
and P
CO
were correlated with pVO
% age-predicted. Prognostication analysis was conducted using pVO
 > 65% age-predicted, as known to represent a low mortality risk. Primary outcome was mortality from any cause.

FW P
CO
was correlated with pVO
(P < 0.0001; r = 0.52), while FW V
/VCO
was not (P = 0.13; r = -0.16). ROC curve analyses showed that FW P
CO
(AUC = 0.659), but not FW V
/VCO
(AUC = 0.587), provided predictive information identifying pVO
 > 65% age-predicted (best cut-off value of 28 mm Hg). By Cox analysis, FW P
CO
 < 28 mm Hg remained a predictor of mortality after adjusting for age and PAH aetiology (HR 2.360, 95% CI 1.144-4.866, P = 0.020).

Low P
CO
during FW is associated with reduced pVO
in PAH and provides predictive information for PAH risk stratification and prognostication.
Low PET CO2 during FW is associated with reduced pVO2 in PAH and provides predictive information for PAH risk stratification and prognostication.Oxidative stress, an imbalance between reactive oxygen species and antioxidants, has been seen in the pathological states of many disorders such as ischemic diseases and cancers. Many natural compounds (NCs) have long been recognized to ameliorate oxidative stress due to their inherent antioxidant activities. The modulation of oxidative stress by NCs via activating the Nrf2 signaling pathway is summarized in the review. Three NCs, ursolic acid, betulinic acid, and curcumin, and the mechanisms of their cytoprotective effects are investigated in myocardial ischemia, cerebral ischemia, skin cancer, and prostate cancer. To promote the therapeutic performance of NCs with poor water solubility, the formulation approach, such as the nano drug delivery system, is elaborated as well in this review.
To describe the patterns of non-insulin antidiabetic medication use, initiation and adherence in the paediatric population.

We conducted a descriptive study of non-insulin antidiabetic medication use in children and adolescents (aged 10-18 years) using real-world data from a nationwide US commercial claims database (January 2004-September 2019). Trends in the prevalence of non-insulin antidiabetic medication use overall and by class were evaluated. Among new users of non-insulin antidiabetic agents, medication adherence was examined using group-based trajectory models.

In a cohort of more than 1 million paediatric patients, the prevalence of any non-insulin antidiabetic medication use was 75.7 per 100 000 patients in 2004 and more than doubled to 162.0 per 100 000 in 2019. Biguanides (metformin) was by far the most widely used medication class. The use of newer classes was low (<10 per 100 000), but there was an uptake in the use of glucagon-like peptide-1 receptor agonists after liraglutide received paediatric approval in 2019.
