Parents and burn survivors generally reported better physical and social outcomes and worse psychological functioning compared to non-burn populations. Physical disabilities were associated with psychological and social functioning in several studies. Follow-up data reported improvements across domains. This review demonstrates the importance of physical, psychological, and social status as long-term outcomes in burn survivors. Mixed findings across three outcome domains warrant long-term research. Findings of this review will guide the foundation of comprehensive burn and age-specific instruments to assess burn recovery.
Patients with aggrecan (ACAN) deficiency present with dominantly inherited short stature, often with advanced skeletal maturation and premature growth cessation. There is a paucity of information on the effects of growth-promoting interventions.
The aim of this study was to evaluate the efficacy and safety of recombinant human growth hormone (rhGH) therapy on linear growth in children with ACAN deficiency.
Open-label, single-arm, prospective study at Cincinnati Children's Hospital Medical Center.
Ten treatment-naïve patients were recruited. Inclusion criteria were a confirmed heterozygous mutation in ACAN, age ≥ 2 years, pre-pubertal, bone age (BA) ≥ chronological age (CA), and normal IGF-I concentration.
Treatment with rhGH (50 mcg/kg/day) over one year.
Main outcomes measured were height velocity (HV) and change in (Δ) height SD (HtSDS).
Ten patients (six females) were enrolled with median CA of 5.6 yrs (range 2.4 to 9.7). Baseline median HtSDS was -2.5 (range -4.3 to -1.1). Median baseline BA was 6.9 yrs (range 2.5 to 10.0), with median BA/CA of 1.2 (range 0.9 to 1.5). Median pre-treatment HV was 5.2cm/y (range 3.8 to 7.1), increased to 8.3cm/y (range 7.3 to 11.2) after one year of therapy (p=0.004). Median ΔHtSDS after one year was +0.62 (range +0.35 to +1.39) (p=0.002). Skeletal maturation did not advance inappropriately (median Δ BA/CA -0.1, p=0.09). No adverse events related to rhGH were observed.
Treatment with rhGH improved linear growth in a cohort of patients with short stature due to ACAN deficiency.

Multiple endocrine neoplasia type 1 (MEN1) is a rare inherited endocrine cancer syndrome. Multiple gastro-entero-pancreatic neuroendocrine tumors (GEP-NETs) affect 30-80% of MEN1 patients, with the most common functioning GEP-NET being gastrinoma. Biochemical identification of hypergastrinemia may help to recognize the presence of gastrinomas before they are detectable by instrumental screening, enabling early diagnosis and start of therapy, preferably before tumor progression and metastases occurrence.
Evaluate the effectiveness of secretin stimulation test to precociously diagnose the presence of gastrin-secreting tumors.
Results of secretin stimulation tests, performed between 1991 and February 2020, were retrospectively analyzed, as aggregate, in a cohort of MEN1 patients with GEP-NETs.
Data were extracted from the MEN1 Florentine database.
The study included 72 MEN1 patients with GEP-NETs who underwent a secretin stimulation test for the evaluation of gastrin secretion.
A positive secretin stimulation test was assumed with a difference between basal fasting serum gastrin (FSG) and the maximum stimulated value of gastrin over 120 pg/ml.
The secretin stimulation test showed a secretin-induced hypergastrinemia in 27.8% (20/72) of patients with GEP-NETs, and a positive test in 18 cases. The test allowed the identification of a positively stimulated hypergastrinemia in 75.0% (3/4) of patients who presented a basal FSG within the normal range.
Diagnosis of gastrinoma is complex, difficult and controversial. Results of this study confirm that a positive secretin stimulation test allows early diagnosis of gastrinomas, even in the presence of borderline or normal levels of non-stimulated FSG.

Prescriptions for oxycodone vary based on the dosage and formulation, immediate release (IR) and controlled release (CR). Monitoring oxycodone metabolites is beneficial for forensic casework. The limited studies that involve pharmacokinetics of the urinary excretion of oxycodone metabolites leave a knowledge gap regarding the excretion of conjugated and minor metabolites, pharmacokinetic differences by formulation, and the impact of CYP2D6 activity on the metabolism and excretion of oxycodone. The objectives of this study were to compare urinary excretion of phase I and II metabolites by formulation and investigate if ratio changes over time could be used to predict the time of intake. Subjects (n=7) received a single 10 mg IR tablet of Oxycodone Actavis. A few weeks later the same subjects received a single 10 mg CR tablet of Oxycodone Actavis. During each setting, urine was collected at 0, 0.5, 1, 1.5, 2, 3, 4, 5, 6, 8, 9, 10, 12, 14, 24, 48, and 72 h. Urine samples (100 µL) were diluted with 900 µL internal standard mixture and analyzed on an Acquity UPLC® I-class coupled to a Waters Xevo TQD using a previously validated method. The CYP2D6 phenotypes were categorized as poor metabolizers (PM), intermediate metabolizers (IM), extensive metabolizers (EM), and ultra-rapid metabolizers (UM). Comparisons between IR and CR were performed using two-tailed paired T-test at a significance level of p=0.05. The metabolite ratios showed a general increase over time. Four metabolite to parent ratios were used to predict the time of intake showing that predictions were best at the early time points.Vital plant functions require at least six metals (copper, iron, molybdenum, manganese, zinc, nickel) which function as enzyme cofactors or inducers. In the past decades, the rapidly evolving nanotechnology has created nanoforms of essential metals (e.g. nZnO, nFe2O3 etc.), having a number of favourable properties over the bulk material. The effects of nanometals on plants are concentration-dependent (hormesis), but also depend on the properties of the nanometals, the plants species and the treatment conditions. This review collects studies examining plant responses to essential nanometal treatments using (multi)omics approach and emphasizes the importance of gaining a holistic view of the diversified effects. Furthermore, the review discusses the beneficial effects of essential nanometals on plants, which provides the basis for their applicability in crop production as nanopriming or nanostimulator agents, nanofertilizers etc. As by the application of essential nanometals lower environmental impact and increased yield can be achieved, nanometals support sustainable agriculture. Recent studies actively examine the utilization of green-synthetized metal nanoparticles, which perfectly fits into the environmental-friendly trend of future agriculture. TTK21 There is still a long way to go before essential nanometals can be safely applied in agricultural, but it is certainly a promising direction that is timely to investigate.
Patients with heart failure (HF) have not been shown to benefit from statins. In a post hoc analysis, we evaluated outcomes in ODYSSEY OUTCOMES in patients with vs. without a history of HF randomized to the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor alirocumab or placebo.
Among 18 924 patients with recent acute coronary syndrome (ACS) receiving intensive or maximum-tolerated statin treatment, the primary outcome of major adverse cardiovascular events (MACE) was compared in patients with or without a history of HF. The pre-specified secondary outcome of hospitalization for HF was also analysed. Overall, 2815 (14.9%) patients had a history of HF. Alirocumab reduced low-density lipoprotein cholesterol and lipoprotein(a) similarly in patients with or without HF. Overall, alirocumab reduced MACE compared with placebo [hazard ratio (HR) 0.85; 95% confidence interval (CI) 0.78-0.93; P = 0.0001]. This effect was observed among patients without a history of HF (HR 0.78; 95% CI 0.70-0.86; P <reduced MACE among patients without a history of HF, but not in those with a history of HF.
The current hypothesis-generating analysis does not provide a basis to recommend PCSK9 inhibitors to patients with recent ACS and a history of HF. A prospective placebo-controlled evaluation of PCSK9 inhibition in this setting is warranted.

One EUA for an oral antiviral drug, molnupiravir, has also been recommended by FDA's Antimicrobial Drugs Advisory Committee, and others appear likely in the near future. Due to increased demand because of the Delta variant, the federal government resumed control over the supply and asked states to ration doses. As future variants with increased infectivity and/or severity (e.g., potentially the Omicron variant) emerge, further rationing may be required. We identify relevant ethical principles (i.e., benefiting people and preventing harm, equal concern, and mitigating health inequities) and priority groups for access to therapies based on an integrated approach to population health and medical factors (e.g. urgently scarce healthcare workers, persons in disadvantaged communities hard hit by COVID-19). Using priority categories to allocate scarce therapies effectively operationalizes important ethical values. This strategy is preferable to the current approach of categorical rules based on vaccination, immunocompromise status, or older age, or the ad hoc consideration of clinical risk factors.
Bipolar radiofrequency ablation (B-RFA) has been reported as a bail-out strategy for the treatment of therapy refractory ventricular arrhythmias (VA). Currently, existing setups have not been standardized for B-RFA, while the impact of conventional B-RFA approaches on lesion formation remains unclear.
(i) In a multicentre observational study, patients undergoing B-RFA for previously therapy-refractory VA using a dedicated B-RFA setup were retrospectively analysed. (ii) Additionally, in an ex vivo model lesion formation during B-RFA was evaluated using porcine hearts. In a total of 26 procedures (24 patients), acute success was achieved in all 14 ventricular tachycardia (VT) procedures and 7/12 procedures with premature ventricular contractions (PVC), with major complications occurring in 1 procedure (atrioventricular block). During a median follow-up of 211 days in 21 patients, 6/11 patients (VT) and 5/10 patients (PVC) remained arrhythmia-free. Lesion formation in the ex vivo model during energy titration from 30 to 50 W led to similar lesion volumes compared with initial high-power 50 W B-RFA.
