Purpose: We investigated the efficacy and safety of 50 and 75 μg desmopressin orally disintegrating tablets in men with nocturia (2 or more nocturnal voids). Materials and Methods: In this 3-month, randomized, double-blind, parallel study 50 and 75 μg desmopressin were compared with placebo. The co-primary efficacy end points were changes from baseline in mean number of nocturnal voids and proportions of patients achieving at least a 33% reduction from baseline in nocturnal voids (33% responders) during a 3-month treatment period. Results: The full analysis set comprised 385 men (age range 20 to 87 years). The 50 and 75 μg doses significantly reduced the number of nocturnal voids (-0.37, p <0.0001 and -0.41, p = 0.0003, respectively) and increased the odds of a 33% or greater response (OR 1.98, p = 0.0009 and OR 2.04, p = 0.0004, respectively) compared with placebo during 3 months. Desmopressin 50 and 75 μg increased the time to first void from baseline by approximately 40 minutes compared to placebo (p = 0.006 and p = 0.003, respectively). The response to desmopressin was seen by 1 week of treatment and was sustained. Significant increases in health related quality of life and sleep quality were observed compared to placebo. Desmopressin was well tolerated as only 2 subjects (age 74 and 79 years) on 50 μg had a serum sodium level of less than 130 mmol/L (vs 9 subjects on 75 μg). Conclusions: Desmopressin (orally disintegrating tablet) is an effective and well tolerated treatment for men with nocturia. Treatment with 50 μg desmopressin, the minimum effective dose, provided sustained improvement of nocturia throughout the study and meaningful benefits to patients with an improved safety profile. © 2013 American Urological Association Education and Research, Inc.

A detailed review of the literature was performed in a bid to identify the presence of a common link between specific hormone interactions and the increasing prevalence of global disease. The synergistic action of unopposed oestrogen and leptin, compounded by increasing insulin, cortisol and xeno-oestrogen exposure directly initiate, promote and exacerbate obesity, type 2 diabetes, uterine overgrowth, prostatic enlargement, prostate cancer and breast cancer. Furthermore these hormones significantly contribute to the incidence and intensity of anxiety and depression, Alzheimer's disease, heart disease and stroke. This review, in collaboration with hundreds of evidence-based clinical researchers, correlates the significant interactions these hormones exert upon the upregulation of p450 aromatase, oestrogen, leptin and insulin receptor function; the normal status quo of their binding globulins; and how adduct formation alters DNA sequencing to ultimately produce an array of metabolic conditions ranging from menopausal symptoms and obesity to Alzheimer's disease and breast and prostate cancer. It reveals the way that poor diet, increased stress, unopposed endogenous oestrogens, exogenous oestrogens, pesticides, xeno-oestrogens and leptin are associated with increased aromatase activity, and how its products, increased endogenous oestrogen and lowered testosterone, are associated with obesity, type 2 diabetes, Alzheimer's disease and oestrogenic disease. This controversial break-through represents a paradigm shift in medical thinking, which can prevent the raging pandemic of diabetes, obesity and cancer currently sweeping the world, and as such, it will reshape health initiatives, reduce suffering, prevent waste of government expenditure and effectively transform preventative medicine and global health care for decades. © 2010 Lippincott Williams & Wilkins, Inc.

Purpose of Review: This review defines current clinical criteria for diagnosis, differential diagnosis, and clinical evaluation of acute disseminated encephalomyelitis, transverse myelitis, and neuromyelitis optica, and summarizes principles of treatment. Recent Findings: Consensus criteria for transverse myelitis and acute disseminated encephalomyelitis have been proposed. A specific biomarker, aquaporin-4 autoantibody, has been discovered for neuromyelitis optica that allows for early and accurate diagnosis even in the absence of cardinal findings of optic neuritis andmyelitis. The antibody is pathogenic and is facilitating an understanding of the pathophysiology of neuromyelitis optica and development of antigen-specific treatments. Summary: Clinical and radiologic findings combined with serologic findings may permit classification of syndromes of transverse myelitis and acute disseminated encephalomyelitis in ways that may predict risk of relapse, type of relapse, and prognosis. Treatment, especially to prevent relapse, is dependent on the specific disease context in which syndromes such as transverse myelitis occur. © 2013, American Academy of Neurology.

Introduction: Subjective memory complaints are common with aging. Docosahexaenoic acid (DHA; 22:6 n-3) is a long-chain polyunsaturated fatty acid (LCPUFA) and an integral part of neural membrane phospholipids that impacts brain structure and function. Past research demonstrates a positive association between DHA plasma status/dietary intake and cognitive function. Objectives: The current meta-analysis was designed to determine the effect of DHA intake, alone or combined with eicosapentaenoic acid (EPA; 20:5 n-3), on specific memory domains: episodic, working, and semantic in healthy adults aged 18 years and older. A secondary objective was to systematically review/summarize the related observational epidemiologic literature. Methods: A systematic literature search of clinical trials and observational studies that examined the relationship between n-3 LCPUFA on memory outcomes in healthy adults was conducted in Ovid MEDLINE and EMBASE databases. Studies of subjects free of neurologic disease at baseline, with or without mild memory complaints (MMC), were included. Random effects meta-analyses were conducted to generate weighted group mean differences, standardized weighted group mean differences (Hedge's g), z-scores, and p-values for heterogeneity comparing DHA/EPA to a placebo. A priorisub-group analyses were conducted to evaluate the effect of age at enrollment, dose level, and memory type tested. Results: Episodic memory outcomes of adults with MMC were significantly (P<.004) improved with DHA/EPA supplementation. Regardless of cognitive status at baseline, > 1 g/day DHA/EPA improved episodic memory (P<.04). Semantic and working memory changes from baseline were significant with DHA but no between group differences were detected. Observational studies support a beneficial association between intake/blood levels of DHA/EPA and memory function in older adults. Conclusion: DHA, alone or combined with EPA, contributes to improved memory function in older adults with mild memory complaints. © 2015 Yurko-Mauro et al.

BACKGROUND: Serum bilirubin has been consistently shown to be inversely related to cardiovascular disease (CVD). Recent studies showed serum bilirubin to be associated with CVD-related factors such as diabetes, metabolic syndrome, and body mass index. Although the association of serum bilirubin with CVD has been found in both retrospective and prospective studies, less information is available on the role of genes that control bilirubin concentrations and their association with CVD. CONTENT: In this review, we provide detailed information on the identity of the major genes that control bilirubin concentrations and their association with serum bilirubin concentrations and CVD risk. We also update the results of the major studies that have been performed on the association between serum bilirubin, CVD, and CVD-related diseases such as diabetes or metabolic syndrome. Studies consistently indicate that bilirubin concentrations are inversely associated with different types of CVD and CVD-related diseases. A conditional linkage study indicates that UGT1A1 is the major gene controlling serum bilirubin concentrations, and this finding has been confirmed in recent genomewide association studies. Studies also indicate that individuals homozygous for UGT1A1*28 have a significantly lower risk of developing CVD than carriers of the wildtype alleles. SUMMARY: Serum bilirubin has a protective effect on CVD and CVD-related diseases, and UGT1A1 is the major gene controlling serum bilirubin concentrations. Pharmacologic, nonpharmacologic, or genetic interventions that increase serum bilirubin concentrations could provide more direct evidence on the role of bilirubin in CVD prevention. © 2010 American Association for Clinical Chemistry.
