Control of mother-to-child transmission of Chagas disease: the Tuscany Region model

Chagas disease is an endemic parasitosis in Latin America where the main route of transmission is vectorial. In Europe, due to migration phenomena, Chagas disease cases are increasing and the main way of transmission is mother-to-child, perpetuating the infection from one generation to the other. Congenital Chagas disease is in most cases asymptomatic at birth, but, if not diagnosed and treated early, it puts the child at risk of developing severe cardiac and gastrointestinal problems throughout life. According to the Regional Resolution throughout the territory of Tuscany, pregnant women born in continental Latin America (or born to a mother born in that area) should be offered free of charge serological test for Chagas disease during pregnancy or at delivery, with the main objective of controlling and stopping the transmission of the disease

The risk of stroke recurrence in patients with atrial fibrillation and reduced ejection fraction

Abstract Background: Atrial fibrillation (AF) and congestive heart failure often coexist due to their shared risk factors leading to potential worse outcome, particularly cerebrovascular events. The aims of this study were to calculate the rates of ischemic and severe bleeding events in ischemic stroke patients having both AF and reduced ejection fraction (rEF) (⩽40%), compared to ischemic stroke patients with AF but without rEF. Methods: We performed a retrospective analysis that drew data from prospective studies. The primary outcome was the composite of either ischemic (stroke or systemic embolism), or hemorrhagic events (symptomatic intracranial bleeding and severe extracranial bleeding). Results: The cohort for this analysis comprised 3477 patients with ischemic stroke and AF, of which, 643 (18.3%) had also rEF. After a mean follow-up of 7.5 ± 9.1 months, 375 (10.8%) patients had 382 recorded outcome events, for an annual rate of 18.0%. While the number of primary outcome events in patients with rEF was 86 (13.4%), compared to 289 (10.2%) for the patients without rEF; on multivariable analysis rEF was not associated with the primary outcome (OR 1.25; 95% CI 0.84–1.88). At the end of follow-up, 321 (49.9%) patients with rEF were deceased or disabled (mRS ⩾3), compared with 1145 (40.4%) of those without rEF; on multivariable analysis, rEF was correlated with mortality or disability (OR 1.35; 95% CI 1.03–1.77). Conclusions: In patients with ischemic stroke and AF, the presence of rEF was not associated with the composite outcome of ischemic or hemorrhagic events over short-term follow-up but was associated with increased mortality or disability

Litter decomposition: effects of temperature driven by soil moisture and vegetation type

Aims We examined the importance of litter quality and microclimate on early-stage litter mass loss, analysed the importance of interactions among environmental factors in determining key decomposition parameters and compared the variation in decomposition rates in vegetation types and sites with similar climate. Methods Following the Tea-Bag Index approach, 464 tea-bags were incubated in the soil in 79 sites, distributed across Italy, which included six vegetation types and a broad range of microclimatic conditions. Results Litter type exerted a stronger control on mass loss compared to climatic factors. The effects of soil moisture were not the same for high and lower quality litter. In addition, the effects of temperature on the decomposition rate depended on soil moisture. The stabilization factor was strongly temperature-dependent, but the influence of temperature differed among vegetation types: those dominated by small-size plants showed a strong decrease in the potential amount of plant material entering into the soil stock under warmer temperatures. The lowest variation in decomposition rate was found in sites characterised by low temperatures, and, among the vegetation types, in alpine snowbeds. Conclusions The role of litter quality and of the interactions among environmental conditions can potentially determine significant shifts in the expected patterns of ecosystem carbon fluxes

Combined Oral Contraception and Bicalutamide in Polycystic Ovary Syndrome and Severe Hirsutism - a Double-blind RTC

Context: Hirsutism often occurs in women with polycystic ovary syndrome (PCOS). The efficacy of oral contraceptive pill (OCP) plus antiandrogens in the treatment of its severe expression is controversial due to the lack of randomized, double-blind, long-term studies. Objective: The primary outcome was the reduction of hirsutism in PCOS women objectively measured by videodermoscopy on the androgen-sensitive skin areas assessed by the modified Ferriman and Gallwey (mF&G) total score, after 12 months of therapy with OCP + bicalutamide (BC) vs OCP plus placebo (P). The secondary outcomes were to evaluate tolerability of BC and body composition as well as the occurrence of adverse events. Design: An experimental, phase 3, prospective, multicenter, randomized, double-blind, P-controlled trial. Patients were evaluated at the baseline visit, at 6 and 12 months during treatment, and 6 months' posttreatment. Participants: Seventy women with classic PCOS (severe hirsutism, oligoanovulation, and ovarian polycystic ovarian morphology). Intervention: Patients received OCP + BC (50 mg/d) or OCP + P for 12 months. Results: The repeated measures analysis of variance showed that both treatments were effective in reducing hirsutism: The OCP + BC group had a higher reduction compared with the OCP + P group. No adverse effects were described during treatment except an increase in total cholesterol and low-density lipoprotein in the OCP + BC group. Conclusions: The association of OCP + BC is well tolerated and significantly more effective than OCP alone in treating severe hirsutism. We suggest a combined use of the videodermoscopic index and mF&G to evaluate the effects of androgen deprivation therapy for hirsutism

Evolution of Clinical Outcome During Adolescents' Psychiatric Inpatient Care: A Prospective Multiple Informant Study

Background: Examining the effectiveness and adequacy of adolescents' psychiatric inpatient treatment through multiple perspectives is crucial to provide the best care. Objectives: The aims of the current study were to examine the consistencies and discrepancies between patients and clinicians and to understand how each group considered the timing of improvement of symptoms and psychosocial difficulties of adolescents during a psychiatric inpatient stay. Methods: The Health of the Nation Outcome Scales for Children and Adolescents (HoNOSCA, assessing symptoms and psychosocial difficulties) was rated on a weekly basis by patients and clinicians during a psychiatric inpatient stay. Data were collected from 297 patients, 58.2% females. Results: Both clinicians and patients reported a significant decrease of the HoNOSCA scores from admission to discharge, revealing that inpatient treatment is perceived as helping the adolescents to alleviate their symptoms and psychosocial difficulties. However, the item- by-item analyses indicated that patients and clinicians reported difficulties in different symptoms and psychosocial domains. Moreover, the week-by-week analyses revealed discrepancies in the perception of the time- course of clinical outcome-changes between clinicians and patients, as well as between males and females, and between voluntarily and involuntarily admitted patients. Conclusion: By integrating perspectives of patients and clinicians and their respective timelines, as well as by taking into account the mode of admission and the patient's gender, this study provides a deeper understanding of the evolution of clinical outcome during adolescents' hospitalizations, which allows to adapt their treatment and therewith, to help patients more efficiently

A Questionnaire Integrated with the Digital Medical Record Improved the Coverage of a Control Program for Congenital Chagas Disease in Tuscany, Italy

The leading route of Chagas disease transmission in nonendemic countries is congenital. However, policies concerning screening, prevention, and management of congenital Chagas disease are rare in these settings. Since 2012, serological screening for Chagas disease should be provided for pregnant women at risk in Tuscany, Italy according to a Regional resolution. Due to difficulties in the implementation, in November 2019, a checklist aimed at identifying pregnant women at risk for Chagas disease was introduced in digital clinical records at Careggi University Hospital, Florence, Italy. In order to evaluate the effectiveness of the “Chagas checklist”, data about the number of deliveries by women at risk and their screening coverage between 2012 and June 2022 were collected. Out of 1348 deliveries by women at risk, 626 (47%) Trypanosoma cruzi serology tests were performed during the study period. The annual screening coverage increased from an average of 40.3% between 2012 and 2019 to 75.7% between 2020 and June 2022, underlining the big impact of the checklist. Four Chagas disease serological tests out of 626 (0.6%) resulted positive, corresponding to 2 affected women. No cases of congenital transmission occurred. The study showed that a simple digital tool led to a tangible improvement in the coverage of the screening program; its application in a setting where digital charts are available will contribute to the control and elimination of congenital Chagas disease

Inicial experience with cinacalcet in Argentina

Introduction: Secondary Hyperparathyroidism is a frequent chronic renal disease complication. Cinacalcet, an allosteric modulator of the calcium sensing receptor, increases its sensitivity to activation by extracellular calcium ions, proved to be effective in reducing PTH levels. Objetive: To evaluate cinacalcet effectiveness in hemodialysis patients with HPTS. Methods: A retrospective, multicenter, observational study was carried out, on 76 patients who received Cinacalcet for at least 3 months, as a treatment for HPTS. Results: The median age was 51±16 years old, 61% were men. 67 months (43-109) was the median time in HD previous to starting with cinacalcet; 40.8% completed one year treatment. Basal PTH median was 1110 pg/ml (887-1477). PTH levels significantly decreased from first month of treatment 874 ( t< 0.0001) to the third 729 p< 0.0001 and to the sixth month 602 p< 0.0001. From the ninth month on, they remained stable, achieving PTH objective levels in 49% of patients that concluded one year treatment. FAL significantly decreased between months 3 and 6, remaining without changes afterwards. There was a significant decrease in calcemia (9.4mg/dl basal to 9 and 8.7 p< 0.0001) and phosphatemia (5.9 mg/dl basal to 5.5 and 5.3, p< 0.0001) in the first and the third month of treatment. Initial 30 mg cinacalcet dose was significantly increased in the 3 and 6 month (mean dose 50mg/day) but without modifications in 9 and 12 months. Conclusion: 50mg/day mean doses correct moderate SHPT but are insufficient for severe SHPT, pointing out the importance of an earlier treatment beginning, and dose tritation according to response
