Bruno Rodrigues, Sandro Anchisi, Pierre-Auguste Petignat, Niels Gobin
Development of oncological treatments has progressively and significantly reduced both mortality and morbidity. Chemotherapy and more recently immunotherapy may have short- and long-term side effects among which, renal involvement is one of the most frequent complications, which may alter therapeutic options and quality of life. High cumulative doses of chemotherapy, concomitant administration of nephrotoxic treatment and pre-existing nephropathy are to be carefully considered. This article intends to review some practical considerations concerning therapies from a nephrological point of view...

PURPOSE: We examined selective laser trabeculoplasty (SLT) as a replacement therapy for medically controlled open-angle glaucoma (OAG) or ocular hypertensive patients. METHODS: A prospective randomized interventional clinical trial on 143 glaucoma patients. Patients were randomized to either receiving SLT or to the control group that continued on pressure lowering medication. Data were recorded 1 hr, 1 week, 1, 3, 6, 12 and 18 months after SLT. Primary outcome was number of medications at 12 and 18 months while maintaining a predetermined target intraocular pressure (IOP)...

Cisplatin (cis-diamminedichlorido-Pt(ii)) is extensively used as a chemotherapeutic agent against various types of tumors. However, cisplatin administration causes serious side effects, including nephrotoxicity, ototoxicity and neurotoxicity. It has been shown that cisplatin can interact with P-type ATPases, e.g., Cu(+)-ATPases (ATP7A and ATP7B) and Na(+),K(+)-ATPase. Cisplatin-induced inhibition of Na(+),K(+)-ATPase has been related to the nephrotoxic effect of the drug. To investigate the inhibitory effects of cisplatin on the pumping activity of PII-type ATPases, electrical measurements were performed on sarcoplasmic reticulum Ca(2+)-ATPase (SERCA) and Na(+),K(+)-ATPase embedded in vesicles/membrane fragments adsorbed on a solid-supported membrane...

PROBLEM IDENTIFICATION: Women taking aromatase inhibitors (AIs) as part of the management of hormone receptor-positive breast cancer experience more symptoms of sexual dysfunction, including vaginal atrophy, as opposed to postmenopausal women and women treated with tamoxifen (Nolvadex®). Vaginal testosterone could be an alternative to estrogen, which is contraindicated in this population.

PURPOSE/OBJECTIVES: Adjuvant endocrine therapy (AET) has been shown to improve survival in hormone receptor-positive breast cancer survivors, but as many as half do not complete recommended treatment. Management of medication-related side effects and engagement with providers are two potentially modifiable factors, but their associations with adherence are not well understood. The aims were to build on survey results to qualitatively explore survivors' experiences with prescribed AET to (a) describe appraisal and management of AET side effects and (b) deconstruct decisions to initiate, discontinue, or maintain AET...

Thyroid hormones, namely 3,5,3'-triiodo-L-thyronine (T3) and 3,5,3',5'-tetraiodo-L-thyronine (thyroxine or T4), influence a variety of physiological processes that have important implications in fetal development, metabolism, cell growth and proliferation. While THs elicit several beneficial effects on lipid metabolism and improve myocardial contractility, these therapeutically desirable effects are associated to a thyrotoxic state, that severely limits the possible use of THs as therapeutic agents. Therefore, several efforts have been made to develop T3 analogues that could retain the beneficial actions (triglyceride, cholesterol, obesity and body mass lowering), without the adverse TH-dependent side effects...

OBJECTIVES: By extending the indication criteria for cochlear implants (CI), the population of CI candidates increased in age, as well as range and type of hearing loss. This qualitative study identified factors that contributed to seek CI treatment in single-sided deaf individuals and gained insights how single-sided deafness (SSD) and hearing with a CI affect their lives. DESIGN: An open-ended questionnaire and a standardised inventory (IOI-HA) were used. Qualitative data reflecting the reasons to seek CI treatment and the individual experiences after CI switch-on were collected...

This pilot study explored predictors of adherence to exercise during and after neoadjuvant chemoradiotherapy (NACRT) in rectal cancer patients. Eighteen rectal cancer patients were prescribed three supervised aerobic exercise sessions/week during NACRT followed by ≥150 min/week of unsupervised aerobic exercise after NACRT. Although not statistically significant, adherence to supervised exercise during NACRT was meaningfully better for patients who were women (d = .82; P = .12), younger (d = -.62; P = ...

Candida species are opportunistic pathogens that infect immunocompromised and/or immunosuppressed patients, particularly in hospital facilities, that besides representing a significant threat to health increase the risk of mortality. Apart from echinocandins and triazoles, which are well tolerated, most of the antifungal drugs used for candidiasis treatment can cause side effects and lead to the development of resistant strains. A promising alternative to the conventional treatments is the use of plant proteins...

Allosteric effect implies ligand binding at one site leading to structural and/or dynamical changes at a distant site. PDZ domains are classic examples of dynamic allostery without conformational changes, where distal side-chain dynamics is modulated on ligand binding and the origin has been attributed to entropic effects. In this work, we unearth the energetic basis of the observed dynamic allostery in a PDZ3 domain protein using molecular dynamics simulations. We demonstrate that electrostatic interaction provides a highly sensitive yardstick to probe the allosteric modulation in contrast to the traditionally used structure-based parameters...

Dopamine replacement therapy (DRT) reduces motor symptoms in Parkinson's disease (PD), but also induces impulsive-compulsive behavior (ICB) in up to 25% of PD patients. These non-motor side effects of DRT generally follow a gradual transition from impulsive to compulsive-like-i.e. repetitive, compelled, and non-pleasurable-behavior. Here, we investigated the effect of chronic pramipexole (PPX) treatment on the onset of compulsive-like behavior, measured via the post-training signal attenuation (PTSA) procedure, in rats with dopaminergic lesions...

A tight interaction between endocrine and immune systems takes place mainly due to the key role of head kidney in both hormone and cytokine secretion, particularly under stress situations in which the physiological response promotes the synthesis and release of stress hormones which may lead into immunomodulation as side effect. Although such interaction has been previously investigated, this study evaluated for the first time the effect of stress-associated hormones together with their receptor antagonists on the expression of cytokine genes in head kidney primary cell culture (HKPCC) of the freshwater rainbow trout (Oncorhynchus mykiss) and the seawater gilthead sea bream (Sparus aurata)...

The molecular mechanism of proton pumping by heme-copper oxidases (HCO) has intrigued the scientific community since it was first proposed. We have recently reported a novel technology that enables the continuous characterisation of proton transport activity of a HCO and ubiquinol oxidase from Escherichia coli, cytochrome bo3, for hundreds of seconds on the single enzyme level (Li et al. J Am Chem Soc 137 (2015) 16055-16063). Here, we have extended these studies by additional experiments and analyses of the proton transfer rate as a function of proteoliposome size and pH at the N- and P-side of single HCOs...

The development of vaccines for aquaculture has been an important milestone in providing a continuous and sustainable production. Most of the vaccines currently on the market for aquaculture include oil as adjuvant. Nevertheless, several studies reported an occurrence of side effects after their use in farmed fish. As a result, there is a need for new and improved adjuvants that can stimulate the immune system while causing as few side-effects as possible. Hemocyanins are versatile macromolecules with strong immunogenic and immunomodulatory properties...

Ultrasonic irradiation has recently gained attention of researchers for its process intensification in numerous reactions. Earlier ultrasound was known for its application either to deactivate enzyme activity or to disrupt the cell. However, in recent years, practice of ultrasonic irradiation began to emerge as a tool for the activation of the enzymes under mild frequency conditions. The incorporation of ultrasound in any of enzymatic reactions not only increases yield but also accelerates the rate of reaction in the presence of mild conditions with better yield and less side-products...
