BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) and substance use disorder are often comorbid in adults. The effects of ADHD treatment on comorbid alcohol use disorder have not been extensively studied. OBJECTIVE To assess correlates of ADHD and alcohol use outcomes in ADHD with comorbid alcohol use disorders, via a post-hoc exploratory(More)
BACKGROUND Levels of cholesterol are regulated by its synthesis, absorption, and elimination. Plasma levels of phytosterols (e.g., sitosterol, campesterol) and ratios of these sterols to total cholesterol (TC) are reported to correlate with efficiency of intestinal cholesterol absorption, whereas levels of certain cholesterol precursor sterols (e.g.,(More)
OBJECTIVE The use of Framingham equations to determine 10-year absolute coronary risk ('global risk') represents an accepted strategy to target coronary prevention measures and enhance clinical outcomes. The aim of this study was to determine the effects of providing global risk scores to physicians on the prescription of lipid-lowering therapy for patients(More)
BACKGROUND The relatively short durations of the initial pivotal randomized placebo-controlled trials involving atomoxetine HCl for the treatment of attention-deficit/hyperactivity disorder (ADHD) provided limited insight into the time courses of ADHD core symptom responses to this nonstimulant, selective norepinephrine reuptake inhibitor. The aim of this(More)
BACKGROUND Few studies have been conducted in actual clinical practice settings to evaluate the ways in which dyslipidemia is managed using lipid-modifying therapies. OBJECTIVE To determine lipid-modifying therapy practices and their effects on low-density lipoprotein cholesterol (LDL-C) and/or total cholesterol (TC) goal attainment in Europeans based on(More)
Type 2 diabetes mellitus is associated with progressive decreases in pancreatic beta-cell function. Most patients thus require increasingly intensive treatment, including oral combination therapies followed by insulin. Fear of hypoglycemia is a potential barrier to treatment adherence and glycemic control, while weight gain can exacerbate hyperglycemia or(More)
Elevated levels of triglycerides (and triglyceride-rich lipoproteins) are increasingly being recognized as treatment targets to lower cardiovascular risk in certain patient subgroups, including individuals receiving HMG-CoA reductase inhibitors (statins). Evidence suggests that these agents reduce the risk of coronary events more markedly in patients with(More)
OBJECTIVE British clinical guidelines recommend statins as first-line lipid-modifying treatment (LMT) for patients at high risk of cardiovascular disease (CVD). We undertook an observational study to assess total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) levels in high-risk patients who were treated with atorvastatin monotherapy by UK(More)
OBJECTIVE To assess patient and partner preferences for, and satisfaction with, tadalafil or sildenafil (phosphodiesterase type 5 inhibitors) in routine clinical practice for treating erectile dysfunction (ED), as these are important outcomes that might influence treatment adherence. PATIENTS AND METHODS In a multicentre, prospective observational trial(More)
A chronic condition that compromises many patients' quality of life, psoriasis is treatable with a range of agents, either alone or in combination. Clinical management strategies using these therapies can be organized as a stepped-care approach. For mild disease, corticosteroids and other topical therapies (step 1) are often appropriate. When lesions are(More)
