Superior Response (superior + response)
Selected AbstractsAtypical depression: retrospective self-reporting of treatment effectivenessACTA PSYCHIATRICA SCANDINAVICA, Issue 3 2009G. Parker Objective:, Earlier studies demonstrated that those with atypical depression show a differentially superior response to monoamine oxidase inhibitor (MAOI) antidepressants. This study compares ratings of effectiveness for a range of treatments, amongst depressed subjects with and without atypical features. Method:, In an on-line survey, individuals experiencing likely clinical depression rated symptoms experienced when depressed, including ,atypical features' and the effectiveness of previous treatments. Mean treatment effectiveness ratings were compared amongst those with ,atypical depression' (n = 338) and ,non-atypical depression' (n = 377). Results:, There were few significant differences between the ,atypical depression' and ,non-atypical depression' groups in effectiveness ratings for drug treatments, and none for psychological treatments. The ,atypical depression' group had significantly lower mean effectiveness ratings for some selective serotonin reuptake inhibitor antidepressants. Few respondents had trialed MAOIs. Conclusion:, While MAOIs are rarely prescribed, a range of non-MAOI drug and psychological treatments are of some perceived benefit for depressed patients with atypical features. [source] Decremental Ramp Atrial Extrastimuli Pacing Protocol for the Induction of Atrioventricular Nodal Re-entrant Tachycardia and Other Supraventricular TachycardiasPACING AND CLINICAL ELECTROPHYSIOLOGY, Issue 10 2006BHARAT K. KANTHARIA M.D. Aim: The primary aim of this study was to evaluate the utility of decremental ramp atrial extrastimuli pacing protocol (PRTCL) for induction of atrioventricular nodal re-entrant tachycardia (AVNRT), and other supraventricular tachycardias (SVTs), compared to standard (STD) methods. Methods: The study cohort of 121 patients (age 57.51 ± 14.02 years) who presented with documented SVTs and/or symptoms of palpitations and dizziness, and underwent invasive electrophysiological evaluation was divided into Group I (AVNRT, n = 42) and Group II (Control, n = 79). The PRTCL involved a train of six atrial extrastimuli, delivered in a decremental ramp fashion. The STD methods included continuous burst and rapid incremental pacing up to atrioventricular (AV) block cycle length, and single and occasionally double atrial extrastimuli. Prolongation in the Atrio-Hisian (,-AH) intervals achieved by both methods were compared, as were induction frequencies. Results: In Group I, three categories of responses,(1) induction of AVNRT, (2) induction of echo beats only, and (3) none,were observed in 29 (69%), 11 (26%), and 2 (5%) patients with the PRTCL, when compared with 14 (33%), 16 (38%), and 12 (29%) patients with STD methods in the baseline state without the use of pharmacological agents. The ,-AH intervals for each of these three categories were larger using PRTCL versus STD methods; 293.3 ± 95.2 ms versus 192.9 ± 61.4 ms (P < 0.005), 308.6 ± 68.5 ms versus 189. 9 ± 64.9 ms (P < 0.0005), and 203.0 ± 86.3 ms versus 145.8 ± 58.9 ms (P = NS), respectively. In Group II, in one patient with dual AV nodal physiology but no clinical tachycardia, the PRTCL induced nonsustained (12 beats) AVNRT. Additionally, in this group, both PRTCL and STD methods induced atrial tachycardia in two patients and orthodromic AV re-entrant tachycardia in one patient. Conclusion: Decremental ramp atrial extrastimuli pacing PRTCL demonstrates a superior response for induction of typical AVNRT as compared to STD techniques. Because of easy and reliable induction of AVNRT and echo beats by the PRTCL, we recommend it as a method to increase the likelihood of induction of AVNRT. For induction of other SVTs, the PRTCL and the STD methods are comparable. [source] Solute Heterogeneity and Osmotic Adjustment in Different Leaf Structures of Semi-Leafless Pea (Pisum sativum L.) Subjected to Water StressPLANT BIOLOGY, Issue 5 2002E. M. González Abstract: Semi-leafless varieties of pea have considerable agronomic importance and it has been suggested that they may have a superior response to water deficits than conventional varieties. However, these varieties are poorly characterized from a physiological point of view and there is lack of a physiological basis for their supposed better performance under conditions of water deficit. Here, we describe the solute distribution in the different leaf structures of a semi-leafless pea variety (Pisum sativum L.) under non-limiting water conditions and under water stress. A conventional variety was subjected to the same conditions for comparative purposes. A detailed study was carried out both at the tissue level and at the single cell level. In control conditions, epidermal vacuoles of tendrils showed a different ion distribution of those of the laminar leaf structures. However, under water deficit, only stipules of the semi-leafless variety showed a significantly higher capability to increase osmolarity. This occurred by accumulating potassium, magnesium and chloride to a higher extent than other leaf structures. The inability of performing an adequate osmotic adjustment in tendrils may be the cause of the lack of a better response to water deficit. [source] Mannose-binding lectin gene polymorphism and resistance to therapy in women with recurrent vulvovaginal candidiasisBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 10 2008GGG Donders Precis, Women with recurrent vulvovaginal candidiasis (RVC) due to a polymorphism in codon 54 of the MBL2 gene respond better to fluconazole maintenance therapy than do women with other underlying causes. Objective, To explain differences in response rates to maintenance therapy with fluconazole in women suffering from RVC by evaluating associations with a polymorphism in the gene coding for mannose-binding lectin (MBL). Design, Follow-up study, neted case-control group. Setting, Women attending vulvoginitis clinic for RVC. Population, Women participating in a multicentric study in Belgium with a degressive dose of fluconazole for RVC (the ReCiDiF trial) were divided into good responders, intermediate responders and nonresponders according to the number of relapses they experienced during therapy. From 109 of these women with adequate follow-up data, vaginal lavage with 2 ml of saline were performed at the moment of a proven acute attack at inclusion in the study, before maintenance treatment was started. A buccal swab was obtained from 55 age-matched women without a history of Candida infections, serving as a control group. Methods, Extracted DNA from buccal or vaginal cells was tested for codon 54 MBL2 gene polymorphism by polymerase chain reaction and endonuclease digestion. Main outcome measures, Frequency of MBL2 condon 54 allele B in women with optimal or poor response to maintenance therapy in composition with controls. Results, Women (n = 109) suffering from RVC were more likely to carry the variant MBL2 codon 54 allele B than control women (20 versus 6.6%, OR 3.4 [95% CI 1.3,8.2], P = 0.01). B alleles were present in 25% of the 36 women not suffering from any recurrence during the maintenance therapy with decreasing doses of fluconazole (OR 4.9 [95% CI 1.9,12.5], P = 0.0007 versus controls), in 20% of the 43 women with sporadic recurrences (OR 3.6 [95% CI 1.4,9.2], P = 0.007 versus controls) and in 15% of the 30 women who had to interrupt the treatment regimen due to frequent relapses (P = 0.097 versus controls). Conclusions, The MBL2 codon 54 gene polymorphism is more frequent in Belgian women suffering from RVC than in controls. The presence of the B allele is associated with a superior response to fluconazole maintenance therapy as compared with RVC patients without this polymorphism. We conclude that RVC due to deficient MBL production is more easily helped with antifungal medication than is RVC due to some other mechanism. [source] |
