The aim of this study was to develop and calibrate a macroporous ceramic passive sampler (MCPS) for the monitoring of anticancer drugs in wastewater. This system was designed by the Spanish Research Council (CSIC) and consists in a porous ceramic tube to allow a high diffusion of contaminants. The MCPS has been calibrated for 16 cytostatic drugs over time periods up to 9 d in spiked water under controlled laboratory conditions. Optimal uptake was accomplished for 7 compounds, namely ifosfamide, cyclophosphamide, capecitabine, prednisone, megestrol, cyproterone and mycophenolic acid, whereas cytarabine was not adsorbed in the receiving phase and the rest were hydrolyzed over the deployment period...

Weight loss is distressing to cancer patients and caregivers. Anorexia/cachexia syndrome is characterized by lipolysis and the loss of lean body mass, and is not reversible by increasing caloric intake. The pathophysiology of cancer cachexia is complex and includes symptoms that impact caloric intake, as well as chronic inflammation, hypermetabolism, and hormonal alterations. Cancer patients require routine screening for cachexia and, ideally, interventions should be initiated in the early stages of weight loss...

Cancer cachexia is a multifactorial syndrome characterized by skeletal muscle loss leading to progressive functional impairment. Despite the ubiquity of cachexia in clinical practice, prevention, early identification, and intervention remain challenging. The impact of cancer cachexia on quality of life, treatment-related toxicity, physical function, and mortality are well established; however, establishing a clinically meaningful definition has proven challenging because of the focus on weight loss alone. Attempts to more comprehensively define cachexia through body composition, physical functioning, and molecular biomarkers, while promising, are yet to be routinely incorporated into clinical practice...

BACKGROUND: Cachexia is a complex metabolic syndrome associated with cancer. One of the features of cachexia is the loss of muscle mass, characterized by an imbalance between protein synthesis and protein degradation. Muscle atrophy is caused by the hyperactivation of some of the main cellular catabolic pathways, including autophagy. Cachexia also affects the cardiac muscle. As a consequence of the atrophy of the heart, cardiac function is impaired and mortality is increased. Anti-cachectic therapy in patients with cancer cachexia is so far limited to nutritional support and anabolic steroids...

A man aged 65 years with metastatic renal cell carcinoma presented for evaluation after a recent fall. A thorough workup of the case was performed and secondary adrenal insufficiency induced by the administration of megestrol acetate was determined to be the cause. Adrenal insufficiency is a serious disorder that is a potential adverse event of megestrol acetate, a medication used to help patients with cancer cachexia increase their appetite and gain weight. This association is not well recognized in clinical practice, so this case highlights the importance of distinguishing possible endocrine complications induced by the long-term administration or sudden discontinuation of megestrol acetate...

UNLABELLED: <u> OBJECTIVE: </u> The conventional suspension of megestrol acetate contains micronized megestrol acetate, which was recently discovered to have a disadvantage of decreasing bioavailability when taken in a fasting state. Since megestrol acetate is taken to increase appetite, this property becomes a discouraging factor. To improve upon this, an advanced formulation was developed using a nanocrystal drug-delivery system. This study was conducted to compare the safety and pharmacokinetic characteristics between the conventional formulation of megestrol acetate and a generic version of the advanced formulation containing nanocrystals...

INTRODUCTION: Meningioma comprise 20-30% of all primary brain tumors. Notwithstanding surgery and radiotherapy, a subset of patients will manifest recurrent meningioma. Systemic therapy is recommended only when further surgery and radiotherapy are not possible. No prospective study with a high level of evidence is available to inform as to recommendations regarding systemic therapy. AREAS COVERED: We aim to summarize systemic therapies for recurrent meningioma. Expert commentary: Hydroxurea, temozolomide, irinotecan, the combination of cyclophosphamide/adriamycine/vincristine, interferon-alpha, somatostatin analogs, mifepristone, megestrol acetate, imatinib, erlotinib and gefitinib are considered as having limited efficacy...

BACKGROUND: The effectiveness of drugs aimed at counteracting cancer cachexia is generally tested in pre-clinical rodent models, where only the tumour-induced alterations are taken into account, excluding the co-presence of anti-tumour molecules that could worsen the scenario and/or interfere with the treatment. METHODS: The aim of the present investigation has been to assess the efficacy of a multifactorial treatment, including formoterol and megestrol acetate, in cachectic tumour-bearing rats (Yoshida AH-130, a highly cachectic tumour) undergoing chemotherapy (sorafenib)...
