Apoptotic cell death is essential for development, immune function or tissue homeostasis, and its mis-regulation is linked to various diseases. Mitochondrial outer membrane permeabilization (MOMP) is a central event in the intrinsic apoptotic pathway and essential to control the execution of cell death. Here we review current concepts in regulation of MOMP focusing on the interaction network of the Bcl-2 family proteins as well as further regulatory elements influencing MOMP. As MOMP is a complex spatially and temporally controlled process, we point out the importance of single-molecule techniques to unveil processes which would be masked by ensemble measurements. We report key single-molecule studies applied to decipher the composition, assembly mechanism and structure of protein complexes involved in MOMP regulation.Hypoparathyroidism (HypoPT) and pseudohypoparathyroidism (PHP) are diseases with abnormal calcium and phosphate homeostasis and low and high PTH levels, respectively. It has been hypothesized that this could dispose to vascular calcifications and thereby perhaps also cardiovascular morbidity. The aim of this study was to assess lower leg arterial calcifications (LLAC) in patients with HypoPT or PHP. Using a cross-sectional design, we measured the LLAC using a high-resolution peripheral quantitative computed tomography (HR-pQCT) scanner in 72 patients with HypoPT and 25 patients with PHP and compared them with findings in 61 controls. LLAC were found in only two (3%) of the controls. Compared to the controls, LLAC were significantly more prevalent in patients with HypoPT (N = 12, [17%], p  less then  0.01) and PHP (N = 4, [16%], p  less then  0.04). Compared to the patients without calcifications, patients with calcifications had higher plasma calcium levels and a lower eGFR, as well as they were older and more often males. Plasma phosphate levels and the calcium-phosphate product were not associated with LLAC. In conclusion, we found that HypoPT and PHP are associated with an increased prevalence of vascular calcifications.
  The present research aimed to investigate the anti-inflammatory potential of dietary anthocyanin (ACN) in type 2 diabetic (T2D), T2D-at-risk and healthy individuals. Furthermore, dietary inflammatory index (DII) was used to study the association of diet with biomarkers of inflammation.
 
  An open-label clinical trial was conducted at Griffith University investigating the efficacy of 320mg ACN supplementation per day over the course of 4 weeks. Diabetes-associated inflammatory biomarkers and relevant biochemical and physical parameters were tested pre-and post-intervention, and participants' dietary inflammatory potential was estimated.
 
  A significant reduction in the pro-inflammatory biomarkers' interleukin-6, interleukin-18, and tumour necrosis factor-α was observed in the T2D group. In addition, some, but not all, biochemical parameters including fasting blood glucose, low-density lipoprotein cholesterol and uric acid were significantly improved in T2D-at-risk group. Moreover, a significant difference was detected between the DII scores of the healthy and T2D groups. DII score for the T2D group was consistent with an anti-inflammatory diet.
 
  Anti-inflammatory potential of dietary ACN in T2D participants was evidenced in the present study. Although, anti-inflammatory dietary patterns of T2D participants may have accelerated the anti-inflammatory effect of the ACN capsules supplemented in this trial.

Most children acquire infection from an adult household member. Children may stay asymptomatic, have a pre-symptomatic stage, or present with symptoms (fever, cough, and difficulty breathing being the most common). Nearly one-third of the pediatric cases (32%) in the United States occurred in children age 15 to 17 years. Children are also at risk of a postinfectious hyperinflammatory syndrome called multisystem inflammatory syndrome in children (MIS-C). The risk of vertical transmission is low (2%) in newborns of mothers with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. Nucleic acid amplification testing (NAAT) is the gold standard for (SARS-CoV-2). Serology should be considered in a child with high clinical suspicion for COVID-19 when NAAT is negative and at least 2 weeks have passed since symptom onset and for assessment of MIS-C. Easy fatigability after COVID-19 infection is reported in adults; however, data in children are lacking. Implementation of early and robust containment strategies coupled with universal COVID-19 vaccination are vital to halt the spread.

In the context of the coronavirus disease 2019 pandemic, mental health symptoms in children, adolescents, families, and health care clinicians are rising. Mindfulness is an approach to improve both mental and physical health that can be practiced freely in any circumstance. Although not a panacea, research does support the use of mindfulness-based practices not only to improve overall well-being but also to address a variety of symptoms and diagnoses in numerous populations. This review defines mindfulness, describes the current state of the literature, outlines ways to support youth and families in cultivating and applying mindfulness in their daily lives, and provides guidance for health care clinicians on how to begin a personal practice to support their own health and well-being.

Although NSSI is done without suicidal intent, its occurrence does increase the risk for suicide and is often found with other diagnosable psychiatric conditions. Screening for NSSI should be accompanied by screening for suicidal ideation and comorbid psychiatric disorders to ensure that the patient's current risk is properly assessed and that they have access to the right resources and treatments. This article is a primer for primary care pediatricians for how to talk about and address NSSI in their patients. [Pediatr Ann. 2021;50(2)e72-e76.].
