A study to evaluate the efficacy of cranberry extract supplements in prevention of recurrent urinary tract infections in female patients

Background: Recurrence of urinary tract infections (UTI) are either due to re infection or relapse. Overall likelihood of developing UTI is approximately 30 times higher in women than men due to their anatomical peculiarities. The objective was to evaluate efficacy of cranberry extract supplementations in prevention of recurrent UTI in female patients, assess the quality of life of patients, medication adherence of patients and effect of patient counselling.Methods: A prospective observational study was carried out for a period of 6 months and samples were taken from the Urology Department of Cosmopolitan Hospital, Trivandrum, Kerala. The selected patients were administered with cranberry extract supplements after their regular Antibiotic therapy and were observed for recurrence for a period of six months. Three follow ups were taken and the betterment was assessed using the score from prepared proforma.Results: 84 patients were analysed and among them we observed and concluded that 86.9% of patients were free of recurrent infection. Study shows that E. coli was the commonest infectious organism causing UTI. In this study the most commonly observed symptom of UTI was lower abdominal pain and the most common co morbidity was DM.Conclusions: Through this study it was concluded that the cranberry extract supplements significantly reduced the recurrence of UTI in women. Since the antibiotic prophylaxis is having the risk of developing resistance and side effects, the cranberry extract supplements can be suggested as a best alternative to antibiotics in recurrent UTI prophylaxis

A study to evaluate the impact of patient counselling on the quality of life of female patients with recurrent urinary tract infection

Background: Recurrence of urinary tract infections (UTI) are either due to re infection or relapse. Overall likelihood of developing UTI is approximately 30 times higher in women than men due to their anatomical peculiarities and are normally treated with antibiotics. To evaluate effectiveness of patient counselling in prevention of recurrent UTI in female patients to reduce the risk of developing Antibiotic resistance and assess the quality of life of patients.Methods: A prospective observational study was carried out for a period of 6 months and samples were taken from the urology department of cosmopolitan hospital, Trivandrum, Kerala. Patient counseling was given regarding the disease, drugs and lifestyle modifications. A suitably validated KAP questionnaire was provided to each patient at their visits. By using an EQ-5D-5L questionnaire the quality of life of patients were assessed and analyzed.Results: 84 patients were analyzed. After the counseling knowledge level significantly improved to good from 6.9% to 72.4%, the positive attitude level was improved from 35.6 to 57.5% and the practice level was improved to good from 25.3 to 43.7%. The QOL improved to best from 1.2 to 71.4%. After counseling incidence rate was decreased to zero. The mostly observed risk factor was decreased water intake (69%). The common age group observed was 31-50 (41.7%).Conclusions: Patient counseling had an important impact on medication adherence and QOL of female patients with recurrent UTI. Effective patient counseling and better compliance decreased the incidence of recurrence and improved the quality of life of patients

Effects on pregnancy in mice of passive immunization against ovine LH and human chorionic gonadotrophin

Mice given daily i.p. injections of immunoglobulins against ovine LH on Days 3-7 of pregnancy were devoid of implantation sites on Day 8 whereas mice treated with antibodies to hCG had embryos of normal number and appearance on Day 8. These antibody treatments reduced the mean ± s.d. serum progesterone concentrations from 65.4 ± 15.3 ng/ml (control globulins) to 8.6 ± 4.9 ng/ml (anti-LH) and 9.2 ± 3.1 ng/ml (anti-hCG) on Day 8 and had no differential effect on serum oestrogen levels on Day 4. However, the mice treated with anti-hCG did not litter; resorption of the embryos took place between Days 10 and 14 of pregnancy. Indirect immunofluorescence and quantitative immunoenzymic assays showed the presence of anti-ovine LH and anti-hCG reacting antigens in the mouse feto-placental unit. On Day 6, the values of reacting antigens (mean ± s.d. absorbance units/10 µm section of embryo) were 0.050 ± 0.002 with control globulins, 0.059 ± 0.002 with anti-hCG-Ig and 0.196 ± 0.018 with anti-LH-Ig; the corresponding values on Day 12 were 0.075 ± 0.009, 0.402 ± 0.02 and 0.416 ± 0.015. The quantitative disposition of the reacting antigens to the two types of anti-gonadotrophins seems to bear a temporal relationship to their respective antifertility action. The pregnancy terminating action of immunoglobulins to ovine LH (Days 6, 7 & 8) and hCG (Days 8, 9 & 10) was counteracted by administration of 2 mg medroxyprogesterone acetate on Days 6, 9 and 12, indicating the importance of progesterone in the maintenance of pregnancy in the mouse

Ophiorrhiza, a promising herbaceous source of the anticancer compound camptothecin

Camptothecin is an important source for the synthesis of some of the major anti-cancer agents such as irinotecan and topotecan. Traditional source of camptothecin are prominently woody plants such as Camptotheca acuminata Decne. and Nothopodytes nimmoniana (Graham) Mabb., and the increasing demand for camptothecin leads to the level of threatening their existence. Ophiorrhiza species composed of herbaceous plants with quick growth characteristics which are reported as alternative source of camptothecin. The present review focus on taxonomical status, traditional uses, biological activities and phytochemical constituents with a special attention in bioproduction of camptothecin from Ophiorrhiza species and its future prospects

Charged Particles in a 2+1 Curved Background

The coupling to a 2+1 background geometry of a quantized charged test particle in a strong magnetic field is analyzed. Canonical operators adapting to the fast and slow freedoms produce a natural expansion in the inverse square root of the magnetic field strength. The fast freedom is solved to the second order. At any given time, space is parameterized by a couple of conjugate operators and effectively behaves as the `phase space' of the slow freedom. The slow Hamiltonian depends on the magnetic field norm, its covariant derivatives, the scalar curvature and presents a peculiar coupling with the spin-connection.Comment: 22 page

Isotope hydrochemistry of the lakes in Schirmacher Oasis, East Antarctica

947-953The study aims to find out the ionic and isotopic compositions of some lakes in the Schirmacher Oasis in east Antarctica. The water samples were collected from 12 lakes near the Indian Antarctic station, Maitri. The chemistry of lake water indicates contribution from glacial melt water and lithology of the area. Evaporation from shallow lakes was also found to be controlling the lake water chemistry. The isotopic concentration of the lake waters also indicated input from the melt water from adjacent glaciers. δD varied between -167.2 ‰ and -250.2 ‰ and δ18O from -18.0 ‰ to -31.2 ‰. It was found that diffusion controlled kinetic effect at the liquid-ice interface for different water isotopologues and evaporative enrichment of heavier isotopes from open water bodies determined the slope of the regression line of the lake water

Reactome: a knowledgebase of biological pathways

Reactome, located at http://www.reactome.org is a curated, peer-reviewed resource of human biological processes. Given the genetic makeup of an organism, the complete set of possible reactions constitutes its reactome. The basic unit of the Reactome database is a reaction; reactions are then grouped into causal chains to form pathways. The Reactome data model allows us to represent many diverse processes in the human system, including the pathways of intermediary metabolism, regulatory pathways, and signal transduction, and high-level processes, such as the cell cycle. Reactome provides a qualitative framework, on which quantitative data can be superimposed. Tools have been developed to facilitate custom data entry and annotation by expert biologists, and to allow visualization and exploration of the finished dataset as an interactive process map. Although our primary curational domain is pathways from Homo sapiens, we regularly create electronic projections of human pathways onto other organisms via putative orthologs, thus making Reactome relevant to model organism research communities. The database is publicly available under open source terms, which allows both its content and its software infrastructure to be freely used and redistributed
