We also provide the newest insights into the development of state-of-art techniques that have facilitated the characterization of membrane pores. To understand the physiological role of these peptides/proteins or develop clinical applications, it is essential to uncover the molecular mechanism of how they perforate membranes.Bis(2-ethylhexyl) phthalate (DEHP) is a plasticizer used in several items, non-covalently bound to plastics and easily released, since metabolites were found in human matrices. DEHP is an endocrine disrupter and children are particularly vulnerable and susceptible to DEHP effects due to higher exposure levels and developmental stage. A juvenile toxicity study was performed to identify DEHP hazard and mode of action in Sprague-Dawley rats of both sexes during peri-pubertal period - corresponding to childhood phase - from weaning, post-natal day (PND) 23, to full sexual maturity (PND60); the dose levels of 0, 9, 21 and 48 mg/kg bw/day were derived from LIFE PERSUADED biomonitoring study in children. DEHP was administered by gavage for 28 days (5 days/week); timing of preputial separation and vaginal opening was observed during treatment. Histopathological analysis was performed on adrenals, spleen, liver, thyroid and reproductive organs. The following serum biomarkers were assessed estradiol, testosterone, anti-Mullerian hormone, tetraiodothyronine, thyroid stimulating hormone, adiponectin and leptin. Gene expression on hypothalamic-pituitary area was focused on follicle stimulating, luteinizing, and thyroid stimulating hormones. The results showed that main targets of DEHP during juvenile period were liver and metabolic system in both sexes, while sex-specific effects were recorded in reproductive system (male rats) and in thyroid (female rats). DEHP exposure during peri-pubertal period at dose levels derived from biomonitoring study in children can induce sex-specific imbalances identifying the juvenile animal model as a sound tool to identify hazards for a reliable risk assessment targeted to children.

One Step Nucleic Acid Amplification (OSNA) assay has recently emerged as a rapid molecular diagnostic tool for the detection of lymph node (LN) metastases. It is a molecular technique that analyses the entire LN tissue using a reverse-transcriptase loop-mediated isothermal amplification reaction to detect tumour specific cytoceratin 19 mRNA.

To ascertain the diagnostic accuracy of OSNA assay in detecting LN metastases amongst different types of malignancy.

We systematically searched MEDLINE, SCOPUS, ClinicalTrials.gov, and Cochrane Database, from inception up to August 2020. Quality assessment was performed using the Modified Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2). We calculated pooled diagnostic indices using the random-effects model. Meta-regression and sub-group analyses were performed to address heterogeneity.

31 studies were included in this meta-analysis, including four different types of cancer. The risk of bias and the overall quality of included studies was moderate to high. There was no evidence of publication bias. The pooled diagnostic odds ratio (DOR) for detecting LN metastases in gynaecological, head & neck/thyroid, gastrointestinal and lung cancer were 100.38, 76.17, 275.14, and 305.84, respectively.

Our findings suggest that OSNA assay had a high diagnostic accuracy in detecting metastatic LNs in different types of malignancy. This evidence is constrained by the limited studies available for few tumour types and the rather high heterogeneity for few outcomes.

Evidence for performing contralateral neck dissection (CND) of recurrent oral cavity squamous cell cancers (OCSCC) is lacking.

This is a retrospective study of 78 consecutive OCSCC having ipsilateral recurrence recorded over five years. We screened 1658 OCSCC patients and selected those patients who underwent CND as part of treatment for ipsilateral recurrence.

The median disease-free interval was 32 months. Incidence of contralateral nodal metastasis (CNM) in recurrent OCSCC was 23.1% and of which 14% were occult. The factor significantly influencing CNM was the depth of invasion (DOI)>10mm (p<0.01). In our study, imaging had suboptimal PPV (33%) while it had high NPV (88%) in diagnosing nodal metastasis in recurrent OCSCC.

DOI is the most important factor predicting CNM in case of ipsilateral primary recurrence. PET-CECT has a high NPV and contralateral neck should be addressed in case of tumours with higher DOI.

Family presence in paediatric resuscitation settings is now accepted practice. However, there is limited evidence to guide psychosocial care of these families. This study aimed to increase the understanding of family demographics and needs for psychosocial care at the Royal Children's Hospital, Melbourne, Australia and to identify the factors that impact on families at this time of emotional and social distress.

A retrospective clinical data-mining methodology was utilised (n = 1123). Descriptive and inferential data analysis was undertaken using STATA software to identify population demographics, patterns in service usage and family experience, and to identify factors associated with parents' emotional responses.

Four areas were identified that support evidence-informed psychosocial care for families in paediatric resuscitation contexts 1) family and parent dynamics 2) families' experiences of distress in relation to patient diagnostic category 3) systemic nature of family response, and 4) the identification and analysis of family emotional support needs, which is central to the psychosocial response.
