This is an observational study in adult males and females utilising skin condition measurements using the LumAssure Raman device. Data will be used to determine accuracy under the ROC curve (AUCROC) of the LumAssure device for differentiating between benign and cancerous skin conditions. The measurements will provide data which will be used to establish spectral parameters for different skin conditions. Measurements will be benchmarked against diagnoses from medical specialists, and when available confirmed with histological data.
The main question it aims to answer is :
What is the accuracy, in terms of the area under the ROC curve (AUCROC) of the LumAssure device for differentiating between benign skin conditions and skin cancers in adult males and females? Participants include males and females aged ≥18 years who are undergoing assessment of a skin condition (a lesion or rash) by a dermatologist, general practitioner, or plastic surgeon. Participants' attending the clinics will have their skin conditions examined by a clinician. The LumAssure device will then be used to measure Raman spectra of skin conditions and marked by the clinician. The Raman measurements will be benchmarked against skin condition assessment and, where available, diagnosis by a dermatologist, general practitioner, or a plastic surgeon, and for those lesions undergoing biopsy, confirmed with histology data.

There is an increasing focus on the need to optimise nutrition, lifestyle and metabolism of parents before and during pregnancy and of the infant after birth, but as yet there is limited understanding of the specific influences and of the underlying mechanisms.
This study is a follow up of children from the NiPPeR trial of a nutritional drink enriched with micronutrients, myo-inositol and probiotics taken preconception and during pregnancy. In this setting we will examine the influence of parental nutrition, lifestyle and metabolism before and during pregnancy on child growth, development and well-being; ascertaining growth, adiposity, metabolism, neurobehavioural and health outcomes in the children, and characterising the underlying mechanisms.
The data collected will allow identification of the contributions of parental and offspring characteristics, nutritional, lifestyle and medical factors, social and economic status, ethnicity, genetics, metabolism and microbes to promoting healthy growth, body composition and wellbeing in the children.

The investigators have developed a diagnostic test for the evaluation of the presence of fetal malformations through metabolomic analysis of maternal peripheral blood serum by chromatographic techniques and mass spectrometry, and subsequent mathematical modeling analysis of the data by means of multivariate mathematical models specifically developed for this purpose. The study aims at determining the performance parameters (specificity, sensibility, positive predictive value (PPN), negative predictive value (NPV), etc.) of the test and its applicability. To do this, the investigators will use the serum samples of the patients enrolled in New Zealand in the SCOPE Study (www.scopestudy.net), an international study conducted between years 2004-2008.
