Valacyclovir in Neonatal Herpes Simplex Virus Disease
This is an open-label, single center, pharmacokinetic (PK) study to assess valacyclovir pharmacokinetics and pharmacodynamics in neonates and compare to the pharmacokinetics and pharmacodynamics of the standard of care treatment dose of intravenous acyclovir. 6 (up to 10 infants) with virologically confirmed neonatal herpes simplex virus (HSV) disease who meet all inclusion/exclusion criteria will be enrolled in the study. Study duration is 5 years. Primary objective is to define the pharmacokinetics of valacyclovir and assess its safety in neonates 2-12 weeks of age who are ≥ 34 weeks gestation.

Validation of a Jaundice Diagnostic and Monitoring Device for Low-Resource Settings
A team of researchers at Rice University in partnership with clinicians at Queen Elizabeth Central Hospital created BiliSpec, a low-cost battery-powered reader designed to immediately quantify serum bilirubin levels from a small drop of whole blood applied to a lateral flow strip. The simple and affordable BiliSpec system offers a faster and more cost-effective means to detect neonatal jaundice in under-resourced clinics and determine when phototherapy is needed. The goal of this study is to validate the accuracy of the BiliSpec device in measuring bilirubin levels in neonates relative to the laboratory spectrophotometric bilirubinometer...

Vitamin D and Its Receptor Gene Polymorphisms in Lithuanian, Latvian and Taiwanese Patients With Atopic Dermatitis and Asthma
The role of vitamin D is well known in calcium and phosphate homeostasis; however, in addition to traditional functions, vitamin D has an important role in pathogenesis of different allergic diseases, such as asthma, atopic dermatitis (AD), and food allergy. There are evidences that lower cord blood vitamin D status is observed in infants with eczema. More-over, vitamin D level is decreased in subjects with asthma. One of the most important functions of vitamin D is to modulate the immune system response, both innate and adaptive, by suppressing Th2-type response and increasing natural killer cells. Vitamin D induces a higher level of...

Vitamin D and Photodynamic Therapy for Treatment of BCC in BCNS
The purpose of this research is to evaluate the use of Photodynamic Therapy (PDT) to treat the multiple basal cell carcinoma (BCC) skin cancers in children and adults with Basal Cell Nevus Syndrome (or who have at least 3 BCC tumors present). In addition, the investigators will test a hypothesis (based upon our extensive preclinical studies in mice) that induction of a transient spike in serum Vitamin D levels through administration of dietary Vitamin D (cholecalciferol; D3) can significantly increase PDT efficacy and improve the clearance of cutaneous BCC tumors.

Vitamin D as a Nutritional Neoadjuvant During Photodynamic Therapy of Basal Cell Carcinoma
The purpose of this study is to study 50 patients with multiple Basal Cell Carcinoma (BCC) who will be receiving Photodynamic Therapy (PDT) as treatment for their tumors. This study wants to establish the optimal conditions for treating BCC tumors with PDT. Previous research suggests that taking Vitamin D prior to the start of PDT could help improve the effectiveness of the treatment in eliminating the BCC. Overall, this study will help establish oral Vitamin D3/PDT as a new combination therapy for skin cancer (BCC). Photodynamic Therapy (PDT) is an investigational (experimental) technique that works by combining a photosensitizing topical...

Well-Being and Health-Related Quality of Life in Melanoma Patients During COVID-19 Pandemic
The primary purpose of this study is to gain an understanding of how experiences during the COVID-19 pandemic, regardless of COVID-19 status, may have impacted multiple domains of health-related quality of life and other areas such as COVID-19 specific psychological distress, and disruptions to health care, finances and social interactions. We will also evaluate the extent to which resiliency factors such as social support, perceived benefits under times of stress, and ability to manage stress may buffer associations between COVID-19 experiences and HRQoL. To meet these objectives, we have developed a 10-minute questionnaire that taps into...

What Are the Benefits and Harms of Risk Stratified Screening in the NHS Breast Screening Programme: Study Protocol
This study aims to identify key benefits and harms of integrating risk stratification (the BC-Predict intervention) into the NHS Breast Screening Programme. A non-randomised fully counterbalanced study design will be used, whereby women from screening sites will be offered usual NHS Breast Screening Programme or BC-Predict for an eight month period, followed by a cross-over point where women at each site will be offered the other invention during an eight month period.
