Lawrence H Kwon, Karan Wats, Clive Rosendorff
BACKGROUND: Not only is there a limited number of studies on the effects of vasodilator β-blocker (VBB) therapy on kidney function - specifically, glomerular filtration rate (GFR), serum creatinine (sCr) and proteinuria - but of those that have been reported, the results are mixed. This meta-analysis seeks to assess the efficacy of VBBs on selected renal parameters in hypertensive patients. METHODS: We conducted a meta-analysis of any prospective trial that provided both baseline and follow-up of at least 4 weeks of VBB therapy - carvedilol, labetalol, dilevalol, nebivolol and celiprolol in patients with hypertension...

Anti-Müllerian hormone (AMH) is a protein produced by pre-antral and small antral ovarian follicles. It is an acknowledged marker of ovarian reserve and remaining reproductive capacity, commonly used in reproductive medicine. From the third decade of life, AMH serum levels decrease consecutively up to menopause. Since the standardization of commercial assays, novel contributions of that parameter are being observed. Up to date, there is no screening tool for predicting the age of natural menopause (ANM). The following literature review evaluates the utility of AMH measurement in predicting ANM...

BACKGROUND: Although switching of antiretroviral therapy (ART) is a valid approach for addressing treatment failure in patients with human immunodeficiency virus (HIV), ART changes among those who are well maintained on their current regimens may lead to the development of new side effects or resistance. OBJECTIVE: To examine the effect of first-line regimen switching on subsequent health care utilization and cost among stable HIV patients. METHODS: This was a retrospective claims data study of adult patients with HIV who initiated ART between 2007 and 2013 and had been treated with their initial regimens for at least 6 continuous months...

Organo-lead-halide perovskites are promising materials for optoelectronic applications. Perovskite solar cells have reached power conversion efficiencies over 22% and perovskite light emitting diodes have recently achieved over 11% external quantum efficiency. To date, most research on perovskite light emitting diodes has focused on solution processed films. There are many advantages of a vapor based growth process to prepare perovskite, including ease of patterning, ability to batch process, and material compatibility...

BACKGROUND: Dry eye syndrome is a disorder of the tear film that is associated with symptoms of ocular discomfort. Punctal occlusion is a mechanical treatment that blocks the tear drainage system in order to aid in the preservation of natural tears on the ocular surface. OBJECTIVES: To assess the effects of punctal plugs versus no punctal plugs, different types of punctal plugs, and other interventions for managing dry eye. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2016, Issue 11), MEDLINE Ovid (1946 to 8 December 2016), Embase...

Antibody-drug conjugates (ADCs) are emerging therapeutic agents in the treatment of cancer, and various conjugation strategies and chemical linkers have been developed to efficiently construct ADCs. Despite previous extensive efforts for improving conjugation efficiency and ADC homogeneity, most ADC linkers developed to date load only single payloads. Branched linkers that can load multiple payload molecules have yet to be fully explored. It is logical to envisage that a multi-loading strategy allows for increase in drug-to-antibody ratio (DAR) with less chemical or enzymatic modification to the antibody structure compared to traditional linear linkers, leading to efficient ADC construction, minimal destabilization of the antibody structure, and enhanced ADC efficacy...

Cytomegalovirus (CMV) is the most frequent congenital virus infection worldwide. The risk of congenital CMV (cCMV) transmission is highest in seronegative women who acquire primary CMV infection during pregnancy. A growing body of evidence indicates that secondary CMV infections in pregnant women with preconceptual immunity (either through reactivation of latent virus or re-infection with a new strain of CMV) contribute to a much greater proportion of symptomatic cCMV than was previously thought. Here, we describe a case of symptomatic cCMV infection in the newborn of a woman with proven immunity prior to pregnancy...

Mucopolysaccharidosis type II (MPS II - Hunter syndrome) is an X-linked lysosomal storage disorder caused by a deficiency in the enzyme iduronate-2 sulfatase (I2S), leading to the accumulation of the glycosaminoglycans, affecting multiple organs and systems. Enzyme replacement therapy does not cross the blood brain barrier, limiting results in neurological forms of the disease. Another option of treatment for severe MPS, hematopoietic stem cell transplantation (HSCT) has become the treatment of choice for the severe form of MPS type I, since it can preserve neurocognition when performed early in the course of the disease...

With the advent of very rapid and cheap genome analyses and the linkage of these plus microbial metabolomics to potential compound structures came the realization that there was an immense sea of novel agents to be mined and tested. In addition, it is now recognized that there is significant microbial involvement in many natural products isolated from "nominally non-microbial sources". This short review covers the current screening methods that have evolved and one might even be tempted to say "devolved" in light of the realization that target-based screens had problems when the products entered clinical testing, with off-target effects being the major ones...

In 1988, we introduced impulsive testing of semicircular canal (SCC) function measured with scleral search coils and showed that it could accurately and reliably detect impaired function even of a single lateral canal. Later we showed that it was also possible to test individual vertical canal function in peripheral and also in central vestibular disorders and proposed a physiological mechanism for why this might be so. For the next 20 years, between 1988 and 2008, impulsive testing of individual SCC function could only be accurately done by a few aficionados with the time and money to support scleral search-coil systems-an expensive, complicated and cumbersome, semi-invasive technique that never made the transition from the research lab to the dizzy clinic...

BACKGROUND: International post-licensure studies on rotavirus vaccines have identified an increased risk of intussusception in infants after administration. The first developed rotavirus vaccine (Rotashield (RRV-TV)) was suspended post-licensure in 1999 after an association with intussusception was found. The currently available second-generation rotavirus vaccines (Rotateq (RV5) and Rotarix (RV1)), are recommended as a routine vaccine by the World Health Organisation (WHO). Post-licensure studies of these vaccines have shown a smaller but temporal increased risk for developing intussusception...

OBJECTIVES: The capability to detect ZIKV RNA is of crucial importance for cases confirmation. However, due to the short-lived viremia, the detection of ZIKV RNA in plasma/serum is challenging for samples collected more than one week after onset of clinical illness. We compared the window time and detection rate of ZIKV RNA in different specimen types (plasma, whole blood and urine) collected simultaneously at several times post-symptom onset. METHODS: We examined the presence of ZIKV RNA in matched specimens of whole blood, plasma and urine collected in the same date (3-28 days after symptom onset) from 10 ZIKV infected patients...

Most hand hygiene guidelines recommend that gloves should be changed during patient care when an indication for hand disinfection occurs. Observational studies indicate that the majority of healthcare workers (HCWs) do not disinfect their hands at all during continued glove wear. The aim of this narrative review is to assess the potential benefits and risks for disinfecting gloved hands during patient care for multiple activities with indicated glove use on the same patient. Continued glove wear for multiple activities on the same patient often results in performing procedures, including aseptic procedures with contaminated gloves, especially in a setting where there are many indications in a short time, e...

SILVA (lat. forest) is a comprehensive web resource, providing services around up to date, high-quality datasets of aligned ribosomal RNA gene (rDNA) sequences from the Bacteria, Archaea, and Eukaryota domains. SILVA dates back to the year 1991 when Dr. Wolfgang Ludwig from the Technical University Munich started the integrated software workbench ARB (lat. tree) to support high-quality phylogenetic inference and taxonomy based on the SSU and LSU rDNA marker genes. At that time, the ARB project maintained both, the sequence reference datasets and the software package for data analysis...

Although fractures are associated with short-term reductions in functional status, there is limited information on longer-term burden of fracture. This study documents evidence of an association between fractures and significant declines and functional health and activities that persist but attenuate beyond two years. INTRODUCTION: Although fractures are associated with short-term reductions in functional status and may have other short-term effects on healthcare utilization (hospitalization and follow-up care), there is limited information on long-term burden of fracture beyond 12 to 24 months post-fracture...

BACKGROUND: Surgeon at primary total hip arthroplasty sometimes cannot achieve sufficient cementless acetabular press-fit fixation and must resort to other fixation methods. Despite a predominant use of cementless cups, this issue is not fully clarified, therefore we performed a large retrospective study to: 1) identify risk factors related to patient or implant or surgeon for unsuccessful intraoperative press-fit, 2) check for correlation between surgeons' volume of operated cases and the press-fit success rate...

George Szmukler
The UN Convention on the Rights of Persons with Disabilities spells out in the most up-to-date and specific manner the rights of persons with disabilities. In doing so the Convention presents serious challenges to many conventional practices in respect of people with disabilities, especially those with mental health disabilities. According to a number of authorities, most notably the UN Committee on the Rights of Persons with Disabilities, 'substitute decision-making' is not consistent with the Convention. 'Respect for the rights, will and preferences' is to be regarded as the touchstone for compliance with the Convention...
