BACKGROUND: Trachoma, caused by ocular infection with Chlamydia trachomatis, is the leading infectious cause of blindness worldwide. We conducted the first population-based trachoma prevalence survey in the Casamance region of Senegal to enable the Senegalese National Eye Care Programme (NECP) to plan its trachoma control activities. The World Health Organization (WHO) guidelines state that any individual with trachomatous trichiasis (TT) should be offered surgery, but that surgery should be prioritised where the prevalence is >0...

Renal transplantation is the treatment of choice for end-stage renal disease, during which renal grafts from deceased donors are routinely cold stored to suppress metabolic demand and thereby limit ischemic injury. However, prolonged cold storage followed by reperfusion induces extensive tissue damage termed cold ischemia/reperfusion injury (IRI) and puts the graft at risk of both early and late rejection. The underlying mechanism of IRI is not completely understood and a reliable/ suitable method to protect the renal graft against cold IRI is lacking...

I have been involved with the current interest in de-extinction since early 2012, nearly its beginning. I have given a lot of thought to the potential risks and benefits of de-extinction. But only recently, after deep immersion in discussions around CRISPR-Cas9, the hottest new tool in bioscience since polymerase chain reaction, have I thought about a more fundamental question: how, if at all, is de-extinction special? Are "revived species" just another kind of genetically modified organism, raising essentially the same general concerns? I answer, for the most part, yes...

V I Podzolkov, A I Tarzimanova
The paper highlights the use of telmisartan, one of the currently available angiotensin receptor blockers, for the treatment of patients with hypertension, metabolic syndrome, and those at high cardiovascular risk. Telmisartan treatment allows blood pressure control, provides organ protection at different stages of the cardiovascular continuum, and reduces the risk of cardiovascular diseases and death. The additional properties and pleiotropic activity of the drug determines its wide range of applications in cardiology...

Obesity and overweight are recognized as epidemics of non-communicable diseases in the 21st century. The kidneys are a target organ for obesity, damage to which is considered to be an independent risk factor for the development of renal failure. Obesity-related glomerulopathy (OGP) is one of the types of renal injury in obesity, which is characterized by the development of proteinuria in patients with a body mass index (BMI) of >30 kg/m2 in the absence of other causes of kidney damage. The pathogenesis of OGP is multifactorial...

BACKGROUND: Pain is a common feature of childhood and adolescence around the world, and for many young people, that pain is chronic. The World Health Organization guidelines for pharmacological treatments for children's persisting pain acknowledge that pain in children is a major public health concern of high significance in most parts of the world. While in the past, pain was largely dismissed and was frequently left untreated, views on children's pain have changed over time, and relief of pain is now seen as importantWe designed a suite of seven reviews on chronic non-cancer pain and cancer pain (looking at antidepressants, antiepileptic drugs, non-steroidal anti-inflammatory drugs, opioids, and paracetamol as priority areas) in order to review the evidence for children's pain utilising pharmacological interventions in children and adolescents...

REVIEW
Saurabh Parasramka, Goutham Talari, John L Villano, Myrna Rosenfeld, Jing Guo
BACKGROUND: Recurrent high-grade glioma (HGG) carries an extremely poor prognosis. There is no current standard of care or guideline-based recommendations. Nitrosourea-based multidrug chemotherapy or PCV - procarbazine, lomustine (CCNU) and vincristine - is one of the treatment options at recurrence. There has been no meta-analysis which looks at the benefits and harms of PCV chemotherapy in adults with recurrent HGG. OBJECTIVES: To assess the effectiveness and safety of procarbazine, lomustine, and vincristine (PCV) chemotherapy with other interventions in adults with recurrent high-grade glioma...

PURPOSE: To provide a fast computational method, based on the proximal graph solver (POGS) - a convex optimization solver using the alternating direction method of multipliers (ADMM), for calculating an optimal treatment plan in rotating shield brachytherapy (RSBT). RSBT treatment planning has more degrees of freedom than conventional high-dose-rate brachytherapy due to the addition of emission direction, and this necessitates a fast optimization technique to enable clinical usage. METHODS: The multi-helix RSBT (H-RSBT) delivery technique(1) was investigated for five representative cervical cancer patients...

Matthew Lewis, Marlon Rosenbaum
PURPOSE OF REVIEW: Hypoplastic left heart syndrome (HLHS) is characterized by underdevelopment of the mitral valve, left ventricle, and aorta and is ultimately palliated with a single-ventricle repair. Universally fatal in infancy prior to the advent of modern surgical techniques, the majority of HLHS patients will now reach adulthood. However, despite improvements in early survival, the HLHS population continues to face significant morbidity and early mortality. This review delineates common sources of patient morbidity and highlights areas in need of additional research for this growing segment of the adult congenital heart disease population...

PURPOSE: Post-implant CT-scanning is an essential part of permanent prostate brachytherapy. However, the evaluation of post-implant CT dosimetry is not straightforward due to the edema that can modify the dose to the prostate and to the organs at risk. The aim of this study is to evaluate the impact of the timing of the post-implant CT-scan on the dosimetric results and to verify if the Day 0 scan findings can predict Day 50 scanning. METHODS: 136 consecutive patients who received monotherapy with I-125 implants were selected for this study...
