Efficacy and safety of two polyherbal combinations: E-MA-H and E-MA-HP in male sexual dysfunction

Efficacy and safety of 2 herbal products--E-MA-H at 2 dose levels, low (HLD) and high (HHD), and E-MA-HP (HP) capsules--versus placebo (PL) was evaluated in subjects with male sexual dysfunction. Males aged 21-60 with erectile dysfunction, premature ejaculation, or other form of sexual dysfunction were studied in this triple-blind, randomized, placebo-controlled, parallel-groups trial. Subjects received any one of the following 4 interventions: E-MA-H 2 capsules at night (HLD) for 60 days; E-MA-H 2 capsules twice daily for 30 days, followed by 2 capsules at night for 30 days (HHD); E-MA-HP (HP) 2 capsules twice daily for 60 days; or placebo (PL) 2 capsules twice daily for 60 days. All dosage regimens were standardized to 2 capsules twice daily by using 2 matching placebo capsules as the morning dose for HLD and on days 31-60 for HHD. Efficacy outcome measures were the international index of erectile function; index for premature ejaculation; erectile dysfunction inventory of treatment satisfaction; subjects' and investigators' global assessment. Safety was assessed through adverse events; hematology; blood chemistry. Of 148 subjects enrolled, 1 was excluded from analysis; data on the intention-to-treat population of 147 (PL = 36, HLD = 38, HHD = 37, HP = 36) were analyzed. There was a significant (P < 0.01) increase in the total international index of erectile function score (mean ± SEM) in subjects receiving HLD (16.28 ± 1.39), HHD (15.40 ± 1.22), and HP (18.55 ± 1.36) compared with PL (6.83 ± 1.52). The same pattern was seen with increase in index for premature ejaculation scores: HLD (9.68 ± 1.17), HHD (10.27 ± 1.05), HP (11.36 ± 1.20) versus PL (3.77 ± 1.04). There was no significant difference in effect among the active treatment groups. The incidence of adverse events was similar in all the groups. Laboratory evaluations did not show any clinically significant abnormality in any of the groups. Treatment with HLD, HHD, and HP is well tolerated, and more effective than placebo (P < 0.01), in subjects with erectile dysfunction, premature ejaculation, and other forms of sexual dysfunction.     

Parallel declines in cognition, motivation, and locomotion in aging mice: association with immune gene upregulation in the medial prefrontal cortex

Aging in humans is associated with parallel changes in cognition, motivation, and motoric performance. Based on the human aging literature, we hypothesized that this constellation of age-related changes is mediated by the medial prefrontal cortex and that it would be observed in aging mice. Toward this end, we performed detailed assessments of cognition, motivation, and motoric behavior in aging mice. We assessed behavioral and cognitive performance in C57Bl/6 mice aged 6, 18, and 24 months, and followed this with microarray analysis of tissue from the medial prefrontal cortex and analysis of serum cytokine levels. Multivariate modeling of these data suggested that the age-related changes in cognition, motivation, motor performance, and prefrontal immune gene expression were highly correlated. Peripheral cytokine levels were also correlated with these variables, but less strongly than measures of prefrontal immune gene upregulation. To determine whether the observed immune gene expression changes were due to prefrontal microglial cells, we isolated CD11b-positive cells from the prefrontal cortex and subject them to next-generation RNA sequencing. Many of the immune changes present in whole medial prefrontal cortex were enriched in this cell population. These data suggest that, as in humans, cognition, motivation, and motoric performance in the mouse change together with age and are strongly associated with CNS immune gene upregulation.     

Epidemiology and symptom profile of gastroesophageal reflux in the Indian population: Report of the Indian Society of Gastroenterology Task Force

Background

Gastroesophageal reflux disease (GERD) and its complications are thought to be infrequent in India; there are no data from India on the prevalence of and risk factors for GERD. The Indian Society of Gastroenterology formed a task force aiming to study: (a) the frequency and profile of GERD in India, (b) factors including diet associated with GERD.

Methods

In this prospective, multi-center (12 centers) study, data were obtained using a questionnaire from 3224 subjects regarding the frequency, severity and duration of heartburn, regurgitation and other symptoms of GERD. Data were also obtained regarding their dietary habits, addictions, and lifestyle, and whether any of these were related or had been altered because of symptoms. Data were analyzed using univariate and multivariate methods.

Results

Two hundred and forty-five (7.6%) of 3224 subjects had heartburn and/or regurgitation at least once a week. On univariate analysis, older age (OR 1.012; 95% CI 1.003–1.021), consumption of non-vegetarian and fried foods, aerated drinks, tea/coffee were associated with GERD. Frequency of smoking was similar among subjects with or without GERD. Body mass index (BMI) was similar in subjects with and without GERD. On multivariate analysis, consumption of non-vegetarian food was independently associated with GERD symptoms. Overlap with symptoms of irritable bowel syndrome was not uncommon; 21% reported difficulty in passage of stool and 9% had mucus in stools. About 25% of patients had consulted a doctor previously for their gastrointestinal symptoms.

Conclusion

7.6% of Indian subjects have significant GERD symptoms. Consumption of non-vegetarian foods was an independent predictor of GERD. BMI was comparable among subjects with or without GERD.     

Genetic diagnosis of neuroacanthocytosis disorders using exome sequencing

Neuroacanthocytoses are neurodegenerative disorders marked by phenotypic and genetic heterogeneity. There are several associated genetic loci, and many defects, including gene deletions and insertions, and missense, nonsense, and splicing mutations, have been found spread over hundreds of kilobases of genomic DNA. In some cases, specific diagnosis is unclear, particularly in the early stages of disease or when there is an atypical presentation. Determination of the precise genetic defect allows assignment of the diagnosis and permits carrier detection and genetic counseling. The objective of this report was to utilize exome sequencing for genetic diagnosis in the neuroacanthocytosis syndromes. Genomic DNA from 2 patients with clinical features of chorea-acanthocytosis was subjected to targeted exon capture. Captured DNA was subjected to ultrahigh throughput next-generation sequencing. Sequencing data were assembled, filtered against known human variant genetic databases, and results were analyzed. Both patients were compound heterozygotes for mutations in the VPS13A gene, the gene associated with chorea-acanthocytosis. Patient 1 had a 4-bp deletion that removes the 5' donor splice site of exon 58 and a nucleotide substitution that disrupts the 5' donor splice site of exon 70. Patient 2 had a dinucleotide deletion in exon 16 and a dinucleotide insertion in exon 33. No mutations were identified in the XK, PANK2, or JPH3 gene loci. Exome sequencing is a valuable diagnostic tool in the neuroacanthocytosis syndromes. These studies may provide a better understanding of the function of the associated proteins and provide insight into the pathogenesis of these disorders.     

A calcified central venous fibrin sheath mimicking a fractured catheter

A 75-year-old female with end stage kidney failure had her tunneled central venous dialysis catheter (CVC) removed. A subsequent computed tomopgraphy (CT) scan of the chest reported a filling defect in the central vein that appeared to represent a fractured remnant of the CVC. The catheter had been retained for culture and was available for direct visualization, which showed it to be entirely intact. A subsequent venogram confirmed that the CT findings represented a retained calcified central venous fibrin sheath. As retained CVC fragments may require intervention, this diagnosis should be established carefully. A calcified fibrin sheath associated with a chronic CVC is a known, although rare, complication and should be considered in the differential diagnosis of an apparent CVC fracture prior to further interventions.     

Pigmented transverse nasal band: A distinct presentation

Pigmented transverse nasal band (PTNB) is an interesting morphological entity mainly of cosmetic concern. It is believed to be related to a defect in the development of the nasal cartilages and bones from childhood to adolescence. Some patients may have genetic predisposition. It is asymptomatic in nature and may be associated with certain dermatological conditions such as seborrheic diathesis, dermatosis papulosa nigra, ichthyosis, atopic dermatitis, acne vulgaris, psoriasis, and seborrheic melanosis.     

Salmonella types and antibiotic susceptibility: a six months survey

A total of 51 Salmonella strains were isolated during the six month period of May 1998 till October 1998. Of these, 41 (80.3%) were Salmonella typhi, 5 (9.8%) Salmonella pararyphi A,2 (3.9%) Salmonella worthington and 1 (1.9%) Salmonella senftenberg. The prevalent phage and biotype of Salmonella typhi was E1 (75%) and type 1 (90.2%) respectively. The commonest pattern of multiple drug resistance in Salmonella typhi was ACCoT and 92.5% of these belonged to phage E1. Out of the five Salmonella paratyphi A, one belonged to phage type 1 and the others were untypable. Similarly both the strains of Salmonella typhimurium were untypable. Thus the predominant isolate was Salmonella typhi and the commonest phage and biotype were E1 and biotype1 respectively.     

Feasibility of Assessing Falls Risk and Promoting Falls Prevention in Beauty Salons

Falls are a major public health risk and a leading cause of emergency room visits for people of all ages. Finding ways to increase access to information and evidence-based falls prevention strategies is critically important across the lifespan. We tested the feasibility of conducting a falls risk assessment and awareness program among customers who attend beauty salons. We enrolled 78 customers from 2 beauty salons who completed a written questionnaire as well as several biometric and functional balance tests designed to assess falls risk. On average, enrolled participants were 56 years of age (range: 19–90), female (n = 70, 91%), and Black (n = 47, 62%). Eleven percent of enrolled customers were classified as at high risk of falls because they had reported two or more falls in the last 6 months. We found that younger age, higher education, employment, moderate physical activity, and decreased frequency of salon visits were associated with fewer falls. Results demonstrated initial interest in, and the feasibility of recruiting and enrolling customers into a beauty salon-based falls risk assessment and awareness program. Beauty salons, which are in all communities, represent an innovative setting for reaching people of all ages with life-saving falls prevention information and services.
