Severe recurrent acute attacks of porphyria have traditionally been treated with either prophylactic human haemin or gonadorelin analogues (GnA) in females. Evidence on the most effective treatment for this patient subgroup is lacking. This audit surveyed the use of prophylactic GnA in the UK.Twenty female patients (who experienced between 2 and 45 acute attacks of porphyria requiring hospitalisation and treatment with human haemin prior to GnA prophylaxis) were included in the audit. Data was retrospectively collected based on patient history and case review...

EDITORIAL
Rena Yadlapati, Peter J Kahrilas
Proton pump inhibitor (PPI) therapy is commonly used outside of Food and Drug Administration indication for a broad range of conditions such as extra-esophageal reflux and PPI-responsive esophageal eosinophilia. While this may be appropriate in some scenarios, it has also resulted in widespread inappropriate PPI use. At the same time, data suggesting adverse effects of long-term PPI therapy are multiplying, albeit mainly from low quality studies. The systematic review by Scarpignato et al. (BMC Med 14:179, 2016) addresses this dilemma with a comprehensive analysis of the risks and benefits of PPI use...

OBJECTIVES: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect. DESIGN: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects...

Laura G Leahy
Off-label prescribing and polypharmacy are commonplace in today's health care environment. Patients are treated with multiple medications obtained through multiple providers, and all too frequently, there is no collaboration amongst professionals. Nurses can address these issues by educating themselves and their patients regarding medication indications and uses, side effects, risks, and benefits. By exploring a patient's medication reconciliation, including over-the-counter agents, and identifying the U.S...

A combination of therapies to treat cancer malignancies is at the forefront of research with the aim to reduce drug doses (ultimately side effects) and diminish the possibility of resistance emergence given the multitarget strategy. With this goal in mind, in the present study, we report the combination between the chemotherapeutic drug doxorubicin (DOXO) and the photosensitizing agent pheophorbide a (PhA) to inactivate HeLa cells. Photophysical studies revealed that DOXO can quench the excited states of PhA, detracting from its photosensitizing ability...

INTRODUCTION: Heterotopic ossification (HO) is known to be a common complication after total hip arthroplasty (THA). The minimal invasive (MIS) modified anterolateral approach has become popular in combination with a short stem. We analysed the incidence of HO following short-stem THA using this approach in combination with a postoperative administration of nonsteroidal anti-inflammatory drugs (NSAIDs). MATERIALS AND METHODS: 216 short stems were implanted in 162 patients...

We previously reported that μ-oxo N,N'-bis(salicylidene)ethylenediamine iron [Fe(Salen)], a magnetic organic compound, has direct anti-tumor activity, and generates heat in an alternating magnetic field (AMF). We showed that Fe(Salen) nanoparticles are useful for combined hyperthermia-chemotherapy of tongue cancer. Here, we have examined the effect of Fe(Salen) on human glioblastoma (GB). Fe(Salen) showed in vitro anti-tumor activity towards several human GB cell lines. It inhibited cell proliferation, and its apoptosis-inducing activity was greater than that of clinically used drugs...

Currently available antihyperglycemic agents, despite being effective, provide inadequate glycemic control and/or are associated with side effects or nonadherence. Canagliflozin, a widely used orally active inhibitor of sodium-glucose cotransporter 2 (SGLT2), is a new addition to the therapeutic armamentarium of glucose-lowering drugs. This review summarizes findings from different clinical and observational studies of canagliflozin 300 mg in patients with type 2 diabetes mellitus (T2DM). By inhibiting SGLT2, canagliflozin reduces reabsorption of filtered glucose, thereby increasing urinary glucose excretion in patients with T2DM...

Approximately 60% to 87% of patients with heart failure (HF) report sexual problems, and numbers as low as 31% of HF patients younger than 70 have normal sexual function. When compared with healthy elders, the amount of perceived sexual dysfunction might be similar (around 56%), but patients with HF are reporting more erectile dysfunction (ED) and also perceive that their HF symptoms (20%) or HF medication (10%) is the cause for their problems. The prevalence of ED is highly prevalent in men with cardiac disease and reported in up to 81% of cardiac patients, compared with 50% in the general older population...

BACKGROUND: Shivering is a common postanesthesia adverse event with multiple etiologies. At present tramadol is a widely used drug for the control of shivering. However, tramadol may cause a lot of nausea and vomiting. Hence, the need to find a better drug with less of side effects. The aim of this study was to compare the efficacy of dexmedetomidine and tramadol in the treatment of post-spinal anesthesia (SA) shivering as well as to compare their side-effect profile. MATERIALS AND METHODS: This prospective, double-blind, randomized controlled trial was conducted in a tertiary care hospital...

Aspirin (ASA) is a cardioprotective drug with anti-cardiac fibrosis action in vivo. This study was aimed to clarify the anti-cardiac fibrosis action of ASA and the underlying mechanisms. Two heart injury models (injection of isoproterenol and ligation of the left anterior descending branch) were used in mice to induce cardiac fibrosis. The animals were treated with ASA (10 mg·kg(-1)·d(-1), ig) for 21 and 14 d, respectively. ASA administration significantly improved cardiac function, and ameliorated heart damage and fibrosis in the mice...

Cancer, the multifactorial pathology and to date is the most lethal causes of death in the world. Cyclophosphamide (CPA) and doxorubicin (DOX) are the individually or combindly used two anticancer drugs. The antineoplastic drugs-mediated genetic instability can be overcome by using antioxidants. The study evaluated the cytogenotoxic modulatory potentials of retinyl palmitate (RP) caused by CPA and DOX in Swiss mice. For this, adult Mus musculus of either sex were divided equally regarding to the gender. Toxicogenetic effects were induced by the intraperitoneal (i...

Various biological factors have been implicated in convulsive seizures, involving side effects of drugs. For the preclinical safety assessment of drug development, it is difficult to predict seizure-inducing side effects. Here, we introduced a machine learning-based in vitro system designed to detect seizure-inducing side effects. We recorded local field potentials from the CA1 alveus in acute mouse neocortico-hippocampal slices, while 14 drugs were bath-perfused at 5 different concentrations each. For each experimental condition, we collected seizure-like neuronal activity and merged their waveforms as one graphic image, which was further converted into a feature vector using Caffe, an open framework for deep learning...

Erectile function (EF) is a prerequisite for satisfactory sexual intercourse (SI) and central to male sexual functioning. Satisfactory SI eventually leads to orgasm - a biopsychophysiological state of euphoria - leading to a sense of bliss, enjoyment and positive mental well being. For a psychiatrist, treating ED is self-propelled to harmonize these pleasurable experiences alongside with encouragement of physical wellness and sensuality. Hence, the role of PDE-5i is pivotal in the context of treating ED constitutes a therapeutic challenge...

BACKGROUND: Ketoprofen, a potent anti-inflammatory, analgesic and anti-pyretic drug belonging to the propionic acid class was synthesized in 1968. Rapid absorption, simple metabolism, faster blood brain barrier crossing and high antinociceptive activity are the features responsible for its high use. But, free acidic moiety present in its structure is the major factor that declines its popularity by causing various gastric side effects .Many researchers have chemically modified this drug with the aim to discover an improved and safe NSAID candidate or a new drug with altered activity...
