Warren ripping and poisoning were used to control rabbits on the flood-out plain of a major creek system on Manunda Station, a sheep-grazing property near Yunta in semi-arid South Australia. Rabbit numbers were initially reduced by >99 per cent, as indicated by the number of active entrances remaining in rabbit warrens. After nearly 10 years without follow-up control work, ripped warrens had only two per cent of the pre-control number of active entrances. Poisoning effectively reduced rabbit numbers in the short-term, but had no long-term effect on the number of active entrances, either in ripped or unripped warrens. Perennial shrubs regenerated on and around ripped warrens. Warren ripping on this part of Manunda is a cost-effective management option.

Cytokinins can cause de-etiolation of Arabidopsis thaliana (L.) Heynh. seedlings growing in the dark. Brassinosteroids (BRs) have been considered to regulate negatively the de-etiolation in dark-grown Arabidopsis seedlings. We show here that epi-brassinolide (epi-BL) can partially produce the phenotype of de-etiolation as caused by treatment with cytokinins in the dark, including the development of leaves and epicotyls in the wild-type and the BR-deficient mutant det2. But BRs cannot inhibit hypocotyl elongation, nor restore all the inhibition caused by cytokinins and light. We have found that there are distinct short term and long term phases of induction of de-etiolation by cytokinins. The short-term effect is probably coupled to ethylene in the inhibition of the hypocotyl elongation; the long-term effect causes morphogenesis of leaves and epicotyls. BRs can only regulate de-etiolation in the long term. We propose that the inhibition of hypocotyl elongation of det2 in darkness is caused by the absence of BR-dependent elongation rather than the inhibition caused by the expression of genes for photomorphogenesis. We propose that BRs resemble cytokinins in regulating de-etiolation as positive regulators, and that the inhibition of hypocotyl elongation and the development of leaves and epicotyls in de-etiolation are independent processes.

Catecholamines are known to have short-term regulatory effects on fat cell hexose uptake. We examined the long-term effects of catecholamines on the insulin-sensitive 2-deoxyglucose (dGlc) uptake in cultured 3T3-L1 adipocytes. Prolonged exposure (48 h) to isoproterenol (beta-adrenergic agonist) stimulated the basal dGlc uptake up to 90%. The effect was specific, time, concentration, and protein synthesis dependent and reversible. The effect of insulin was unaltered and superimposed on the increase in basal dGlc uptake. The long-term effect of isoproterenol was mimicked by epinephrine, dibutyryl cAMP (DBcAMP), and 1-methyl-3-isobutylxanthine (IBMX). By contrast, short-term exposure to isoproterenol (and epinephrine) induced a protein synthesis-independent increase in basal dGlc uptake (30%) not accompanied by an increase in insulin responsiveness. Moreover, on short-term basis, DBcAMP and IBMX suppressed both the basal and insulin-stimulated uptake up to 50%. Determination of the intracellular nonphosphorylated dGlc during the uptake and of the hexokinase activity revealed that the long-term effect of isoproterenol was most likely due to alterations low in dGlc transport. In conclusion, long-term regulators of hexose uptake are in cultured 3T3-L1 adipocytes, isoproterenol, and other cAMP stimulators. The long-term effect is independent from the short-term regulatory effect of the agents and from the effect of insulin.

Objective This systematic review aimed to assess the effectiveness of repetitive transcranial magnetic stimulation (rTMS) treatment for chronic tinnitus. Data Sources Relevant electronic databases and a reference list of articles published up to January 2012 were searched. Randomized controlled clinical trials of all types of rTMS treatment for patients with chronic tinnitus were included. Review Methods A literature search was conducted with structured criteria to select studies evaluated for systematic review. Results Five trials (160 participants) were included in this review. Repetitive transcranial magnetic stimulation treatment showed benefits in the short term, but the long-term effects are questionable. The Tinnitus Handicap Inventory (THI) and the visual analog scale (VAS) were the major assessment methods used. After active TMS stimulation, the reduction in the THI total score and VAS was significant compared with baseline at the first time point assessed and in the short term (2 weeks and 4 weeks). The longest follow-up time was 26 weeks after treatment, and the shortest follow-up time was 2 weeks. No severe side effects were reported from the use of rTMS. Differences in age, hearing level, duration of tinnitus of the included patients, and the condition of sham treatment may influence the effect. Conclusion Repetitive transcranial magnetic stimulation could be a new therapeutic tool for the treatment of chronic tinnitus, and thus far we have not been able to demonstrate any substantial risk from rTMS treatment. However, the long-term effects of rTMS treatment for tinnitus are not clear and will require further study.

IntroductionData on the comparative effect of short and long-term psychotherapy in anxiety disorder is scarce.AimTo compare the effectiveness of two short-term therapies and one long-term psychotherapy in the treatment of patients with anxiety disorder.MethodsAltogether 50 outpatients with anxiety disorder as the only axis I diagnosis, were randomly assigned to long-term psychodynamic psychotherapy (LPP), short-term psychodynamic psychotherapy (SPP), and solution-focused therapy (SFT) and were followed for 5 years. The outcome measures were psychiatric symptoms, working ability, need for psychiatric treatment, remission, and cost-effectiveness.ResultsDuring the first year of follow-up, no significant differences in the effectiveness between the therapies were noted. During the following 3 years, LPP and SFT more effectively reduced symptoms, improved work ability, and elevated the remission rate than SPP. No significant differences between LPP and SFT were seen. At the end of the follow-up, the use of auxiliary treatment was lowest in the SFT group whereas remission rates or changes in psychiatric symptom or work ability did not differ between the groups. The average total direct costs were about three times higher in the LPP group than in the short-term therapy groups.ConclusionsThe difference in effectiveness of LPP and SFT was negligible, whereas SPP appeared less effective. Thus, the resource-oriented SFT may be a cost-effective option in this selected patient group, while unconsidered allocation of patients to LPP does not appear to be cost-effective. Given the small number of patients, no firm conclusions should, however be drawn based on this study.Disclosure of interestThe authors have not supplied their declaration of competing interest.

IntroductionParenting interventions during early childhood are known to improve various child development outcomes immediately following programme implementation. However, less is known about whether these initial benefits are sustained over time.MethodsWe conducted a systematic literature review of parenting interventions in low- and middle-income countries (LMICs) that were delivered during the first 3 years of life and had completed a follow-up evaluation of the intervention cohort at least 1 year after the primary postintervention endpoint. We summarized intervention effects over time by child-level and parent-level outcomes as well as by timing of follow-up rounds in the short-term (1–3 years after programme completion), medium-term (4–9 years), and long-term (10+ years). We also conducted exploratory meta-analyses to compare effects on children’s cognitive and behavioral development by these subgroups of follow-up rounds.ResultsWe identified 24 articles reporting on seven randomised controlled trials of parenting interventions delivered during early childhood that had at least one follow-up study in seven LMICs. The majority of follow-up studies were in the short-term. Three trials conducted a medium-term follow-up evaluation, and only two trials conducted a long-term follow-up evaluation. Although trials consistently supported wide-ranging benefits on early child development outcomes immediately after programme completion, results revealed a general fading of effects on children’s outcomes over time. Short-term effects were mixed, and medium-term and long-term effects were largely inconclusive. The exploratory meta-analysis on cognitive development found that pooled effects were significant at postintervention and in the short-term (albeit smaller in magnitude), but the effects were not significant in the medium-term and long-term. For behavioural development, the effects were consistently null over time.ConclusionsThere have been few longer-term follow-up studies of early parenting interventions in LMICs. Greater investments in longitudinal intervention cohorts are needed in order to gain a more comprehensive understanding of the effectiveness of parenting interventions over the life course and to improve the design of future interventions so they can have greater potential for achieving and sustaining programme benefits over time.

Abstract Purpose: We aimed to evaluate long term effects of COVID-19 disease on left ventricular function using speckle tracking echocardiography. Methods: In our study, 96 non-hospitalized patients who were diagnosed with COVID-19 disease in our center between 15 August 2020 and 01 September 2020 and 96 age and gender matched control subjects were included.Results:The mean follow up duration was 137 ± 7 days. White blood cell, neutrophile and lymphocyte were significantly lower and C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) were significantly higher in the COVID-19 group. (6.6 ± 2.8 vs. 24.4 ± 21.8, p <0.001 and 4.1 ± 2.5 vs. 7.1 ± 4, p <0.001, respectively). LV-GLS and LV-GCS were significantly lower in the COVID-19 group. (-20.1 ± 3.1 vs -15.9 ± 2, p <0.001 and -29.3 ± 2.1 vs -26.3 ± 2.1, p <0.001, respectively). LV-GLS and LV-GCS were found to be negatively correlated with CRP (rs = -0.515, p <0.001 and rs = 0.-466, p <0.001, respectively) and NLR (rs = -0.494, p <0.001 and rs = -434, p <0.001, respectively). Conclusion: Deteriorating effects of COVID-19 disease on both LV-GCS and LV-GLS can be seen even in the short term. These detrimental effects seem to be associated with CRP levels and NLR measured in the course of active infection.

Objective: The aim of the study was to compare the long-term effects of radiofrequency ablation (RFA), microdebrider-assisted inferior turbinoplasty (MAIT), and diode laser techniques on the severity of nasal obstruction and quality of life (QOL) in a 3-year follow-up. Methods: The patients filled a Visual Analog Scale (VAS) regarding the severity of nasal obstruction and the Glasgow Health Status Inventory (GHSI) questionnaire preoperatively and during the control visits at 3 months and 3 years. Acoustic rhinometry was also performed. A total of 78 patients attended both control visits. Results: All 3 techniques improved the VAS score for the severity of nasal obstruction and the GHSI total score significantly compared to the preoperative values at both 3 months and 3 years. Compared to the preoperative values, all 3 techniques increased the V2 to 5 cm values significantly at 3 months. After 3 years, compared to the preoperative values, the MAIT ( P = .005) and diode laser ( P < .001) still had a statistically significant volume increase in V2 to 5 cm, whereas the RFA ( P = .06) did not achieve a statistically significant effect. Conclusion: The RFA, MAIT, and diode laser all improved both the patients’ subjective sensation of the severity of nasal obstruction and QOL significantly. The response was sustained during the 3-year follow-up period with all 3 techniques. A weakening in the objective treatment response to RFA was found in the longer follow-up, but that did not cause a weakening of the patients’ subjective treatment response.

Tourism is one of the largest economic sectors in the world. It has a positive effect on the economy of many countries, but it can also lead to negative impacts on local ecosystems. Informal environmental education through Citizen Science (CS) projects can be effective in increasing citizen environmental knowledge and awareness in the short-term. A change of awareness could bring to a behavioral change in the long-term, making tourism more sustainable. However, the long-term effects of participating in CS projects are still unknown. This is the first follow-up study concerning the effects of participating in a CS project on cognitive and psychological aspects at the basis of pro-environmental behavior. An environmental education program was developed, between 2012 and 2013, in a resort in Marsa Alam, Egypt. The study directly evaluated, through paper questionnaires, the short-term (after 1 week or 10 days) retention of knowledge and awareness of volunteers that had participated in the activities proposed by the program. After three years, participants were re-contacted via email to fill in the same questionnaire as in the short-term study, plus a new section with psychological variables. 40.5% of the re-contacted participants completed the follow-up questionnaires with a final sample size of fifty-five people for this study. Notwithstanding the limited sample size, positive trends in volunteer awareness, personal satisfaction regarding the CS project, and motivation to engage in pro-environmental behavior in the long-term were observed.

Pediatricians involved in helping parents of hyperactive children can recommend to them this readable, authoritative manual which by its positive, enthusiastic, but realistic tone will help them deal with difficulties presented by such children. They will find detailed advice on practical methods of influencing their children and their behavior to make life less trying for all in the short term and perhaps even in the long term. The lack of understanding of the basic cause of this abnormality of temperament and the absence of follow-up studies showing that the recommended management has beneficial long-term effects are conceded by the authors as limiting the authority of the text.

Abstract The long-term effect of radiotherapy and bromocriptine treatment was retrospectively evaluated in 25 patients who had previously undergone transsphenoidal surgery for treatment of macroprolactinomas. Surgery had reduced the median serum prolactin (PRL) value from 613 Mg/l to 291 Mg/l, a reduction of 53%. Postoperative bromocriptine was administered to 21 of the 25 patients. In 14 of these patients, serum PRL values became normal or almost normal with medication. There were no radiological or ophthalmological signs of progressive tumor growth during bromocriptine treatment. Fourteen patients received postoperative radiotherapy. After withdrawal of bromocriptine in 13 of these patients an average of 7 years after radiotherapy, the median serum PRL value had further decreased by 95%. The PRL reduction was similar for all doses applied, 38 to 52 Gy. After withdrawal of bromocriptine in 8 patients not receiving radiotherapy an average of 7 years after operation, the median serum PRL level had further decreased by 75%. At follow-up, 18 additional instances of pituitary insufficiency had developed in the group receiving radiotherapy, compared with 8 cases of insufficiency in the group not receiving radiotherapy. Thus, because bromocriptine has a long-standing effect on prolactin secretion, and radiotherapy is associated with a notably high incidence of pituitary insufficiency, we propose that photon irradiation should be considered mainly for patients who are not candidates for surgical or medical treatment.
