Necrotising soft tissue infection (NSTI) is a life-threatening disease with widespread tissue destruction. Immediate and aggressive surgical debridement remains the main focus of treatment. This results in disfiguring scars, functional limitation and psychological sequelae for survivors. As mortality rate declines with improvements in care, a greater focus should be placed upon the psychological and functional outcomes of survivors. This study aims to assess the health-related quality of life (HRQoL) of patients following NSTI using the Short Form-36 (SF-36) and Derriford Appearance Scale-24 (DAS-24).

All NSTI patients admitted at our tertiary referral centre between 1 January 2013 and 31 December 2019 were invited to complete the DAS-24 and SF-36 surveys. A retrospective chart review was also performed.

A total of 30 participants responded to the surveys. On comparison against the general Australian population, the NSTI cohort demonstrated significantly reduced physical and mental HRQoL as measured by the SF-36 (P < 0.001). Increased age was significantly associated with a reduced physical HRQoL (P=0.002), while dysfunction with appearance as measured by the DAS-24 form correlated with both reduced physical and mental HRQoL (P=0.020). A total of 79.3% of patients expressed concern regarding their appearance with a significantly higher level of distress at their appearance compared to a non-clinical population (P=0.120).

Despite the rarity of NSTI, this study demonstrates that this disease has a large and persistent burden for survivors, who report significantly reduced HRQoL and distress with appearance. Further research into comprehensive physical and psychosocial services for NSTI survivors is required.

Children with hepatoblastoma (HB) are at risk of sarcopenia due to immobility, chemotherapy, and malnutrition. find more We hypothesized that children with HB have a low preoperative total psoas muscle area (tPMA), reflecting sarcopenia, which negatively impacts outcome.

Retrospective study of children (1-10years) with hepatoblastoma treated at a large university children's hospital from 2009 to 2018. tPMA was measured as the sum of the right and left psoas muscle area (PMA) at intervertebral disc levels L3-4 and L4-5. z-Scores were calculated using age- and gender-specific reference values and were compared to anthropometric measurements, clinical variables, and outcomes. Sarcopenia was defined as a tPMA z-score below -2.

Thirty-three children were included. Mean tPMA z-score was -2.18 ± 1.08, and 52% were sarcopenic. A poor correlation between tPMA and weight was seen (r=0.35; confidence interval [CI] 0.01, 0.62; P=.045), and most children had weights within the normal range (mean z-score -0.55 ± 1.39). All children categorized as high risk with relapse (n=5/12) were sarcopenic before surgery. Relapse was significantly higher in the high-risk sarcopenic group compared to the nonsarcopenic group (P=.008). The change in tPMA z-score 1-4months after surgery did not improve in patients with relapse, but did improve in 75% of children without relapse.

The majority of children with HB were sarcopenic prior to surgery. Especially in children with high-risk hepatoblastoma, sarcopenia is an additional risk factor for relapse. Large multicenter studies are needed to confirm these preliminary results.

The multiple detecting techniques of m5 C have been developed, such as m5 C-RIP-seq, miCLIP-seq, AZA-IP-seq, RNA-BisSeq, TAWO-seq, and Nanopore sequencing. These high-throughput techniques, combined with corresponding analysis pipeline, provide a precise m5 C landscape contributing to the deciphering of its biological functions. The m5 C modification is distributed along with mRNA and enriched around 5'UTR and 3'UTR, and conserved in tRNAs and rRNAs. It is dynamically regulated by its related enzymes, including methyltransferases (NSUN, DNMT, and TRDMT family members), demethylases (TET families and ALKBH1), and binding proteins (ALYREF and YBX1). So far, accumulative studies have revealed that m5 C participates in a variety of RNA metabolism, including mRNA export, RNA stability, and translation. Depletion of m5 C modification in the organism could cause dysfunction of mitochondria, drawback of stress response, frustration of gametogenesis and embryogenesis, abnormality of neuro and brain development, and has been implicated in cell migration and tumorigenesis. In this review, we provide a comprehensive summary of dynamic regulatory elements of RNA m5 C, including methyltransferases (writers), demethylases (erasers), and binding proteins (readers). We also summarized the related detecting technologies and biological functions of the RNA 5-methylcytosine, and provided future perspectives in m5 C research.

Adrenocortical tumours (ACT) are rare tumours of childhood usually presenting with endocrine dysfunction. This retrospective study is designed to review our institutional experience in surgical management.

Records of children treated for ACT between 1999 and 2019 were reviewed retrospectively.

The median age of 24 children was 78 months. Fourteen patients had adrenocortical carcinoma, nine had adrenocortical adenoma and one had neuroendocrine differentiation of ACT. Endocrine dysfunction was noted in 79% of the patients. Five patients had preoperative chemotherapy but none had a decrease in tumour size. Transabdominal approach was used in all but two patients who had thoracoabdominal incision for excision of giant tumours and ipsilateral lung metastases. Two patients had visceral excision to achieve R0 resection. Five patients, four of whom had spillage and one with partial resection died of widespread disease. Two patients with stage 4 adrenocortical carcinoma are still on chemotherapy. All patients with stage I-III disease who had total excision without spillage (n= 17) are disease-free for 2-170 months.
