Abstract
Abstract
Introduction
Aortic valvular calcium score (AVCS) is useful in patients with aortic stenosis for whom echocardiography was not conclusive in grading its severity. Transcatheter aortic valve implantation (TAVI) is an established procedure of treatment in symptomatic severe AS. The burden of aortic valve calcification has been associated with some TAVI related complications (as perivalvular leaks), but at the same time it is well accepted that some degree of calcification is needed to ensure stable anchoring of the prosthesis to the aortic annulus.
Purpose
To assess if there is a correlation between aortic valve calcium score and mean transvalvular gradient 6 months after TAVI – is a higher AVCS correlated with lower mean transaortic gradient after TAVI?
Methods
We performed a single-center, retrospective cohort study including patients who underwent TAVI with a preoperative standardized contrast enhanced MSCT with AVCS available. Clinical and echocardiographic data were collected previously to TAVI (pre-TAVI) and at 6 months follow up (6M-FUP).
Results
A total of 187 patients were included, with 54% female and a mean age of 79.4±9.0 years old. Most patients had tricuspid aortic valve (95.7%); 5 patients had aortic bicuspidy and 3 had aortic valve bioprothesis. Concerning the valve type, 73.3% had new generation prosthesis and the main valve used was the CoreValve Evolut Pro (33.7%). Also, 38,5% needed balloon pre-dilation before TAVI. The mean pre-TAVI aortic transvalvular maximum and mean gradients were 76.5±23.2 mmHg and 48.3±15.5 mmHg, respectively; mean aortic valve area was 0.75±0.16 cm2. The mean AVCS was 2851±1524 AU (Agaston Units); 81.2% of women had AVCS>1300 AU and 74.4% men had AVCS >2000 AU. Comparing transvalvular aortic gradients previously and 6M-FUP after TAVI, there was an average differential of maximum gradient of 61±22 mmHg and of mean gradient of 40±15 mmHg. A negative and weak correlation was found between the AVCS and the maximum gradient (pearson coefficient of −0.181, p=0.02) and between mean gradient at 6M-FUP (pearson coefficient of −0.191, p=0.014).
Discussion and conclusion
AVCS is a significant predictor for death, stroke and perivalvular leaks after TAVI. On the other hand, high AVCS is associated with better seating in the native annulus during deployment. Nevertheless, high AVCS did not strongly correlated with mean transaortic gradient 6 months after TAVI.

Abstract
Abstract
Introduction
Atrial fibrillation (AF) is the most common sustained arrhythmia in hypertrophic cardiomyopathy (HCM), occurring in approximately 25% of patients, related to left atrial (LA) dilatation and remodeling. HCM patients who develop AF have increased risk of HCM-related death, functional impairment, and stroke. Accurate risk stratification for AF in this population is crucial as contemporary treatments are highly successful.
Purpose
To assess if new echocardiographic parameters can predict the development of AF in HCM patients.
Methods
HCM patients who underwent comprehensive echocardiographic examination during 2011 were followed and checked for “de novo” AF until November 2021. We searched for associations between AF development and novel echocardiographic parameters such as LA Volume index, Left Atrioventricular Coupling Index (LACI, as LAVI/a'), 3D LA volumes and 3D LA ejection fraction (3D-LAEF).
Results
A total of 43 patients were included, with 62.8% male and mean age 56,1±6,2 years old. 55.8% had the septal asymmetric HCM type and mean LV mass was 326±127g. Mean LA diameter and biplane 2D volume was 46±7 mm and 78±37 mL, respectively. 11.6% of patients already had AF. During a median follow-up of 9.4 years, the incidence of “de novo” AF was 31,6%. Within the total 17 patients with AF, 35,2% took warfarin and the remaining direct oral anti-coagulation. No stroke was documented. There were 3 deaths (mortality rate of 7,0%), none from cardiac causes.
No association was found between AF development and LAVI, LACI or 3D LA volumes. We only found a statistically significant difference regarding 3D-LAEF, which was lower in patients who developed AF compared with those without AF (26±12% VS 39±19%, p=0.04).
Binary logistic regression analysis found that reduced 3D-LAEF predicts the development of AF (p=0.019, odds ratio [OR] 2.6, 95% confidence interval [CI] 1.0 to 1.1). The area under a receiver operating characteristic curve using 3D-LAEF as a predictive marker for AF development in HCM patients was 0.743 (p=0.004). When the cut-off value of 3D-LAEF was set at 34,5%, the sensitivity and specificity for AF diagnosis were 66% and 86%, respectively.
Conclusion
In our study, 3D LAEF predicted the development of AF in HCM patients – this may be a useful tool to identify patients at high risk of future AF who may benefit from more intensive rhythm monitoring and a lower threshold for oral anticoagulation.

Abstract
Abstract
Background
Percutaneous valve commissurotomy (PMC) is a viable alternative to mitral valve (MV) surgery in the treatment of patients with clinically significant mitral stenosis (MS). About 40% of patients treated with PMC will require at least one reintervention (either PMC or MVS) along time.
Purpose
To evaluate the long-term results of PMC in patients with rheumatic MS.
Methods
We retrospectively analysed all consecutive patients between 1991 and 2008 with clinically significant rheumatic MS undergoing PMC. Clinical and echocardiographic data were collected at baseline and during early and long-term follow-up. MACE was a composite of adverse events defined as all-cause mortality, MV re-intervention or cardiovascular hospitalization.
Results
A total of 124 patients were enrolled: 108 (87%) were female, with a mean age at the time of PMC of 46±11 years.
At baseline, 34% patients were in NYHA class ≥ III and 81% had a Wilkins score ≤8; all patients had preserved biventricular systolic function and 83% presented pulmonary hypertension. Regarding associated valve disease, 46 patients had mild tricuspid regurgitation (TR), 19 mild aortic regurgitation (AR), 14 moderate IT and 5 moderated AR.
Most of the procedures were successful (91%) and without complications (94%), with median improvement in MV area of 0.9 cm2 (IQR 0.5) and median reductions in mean transmitral gradient (MTG) of 6 mmHg (IQR 6) and in pulmonary artery systolic pressure (PASP) of 8 mmHg (IQR 10) early after PMC.
During the mean follow-up of 20±6 years, 52 (42%) of patients had MV re-intervention (86% surgery and 14% re-PMC), 37 (30%) were hospitalized and 30 (24%) died. Concerning time-to-event analysis, approximately 80% of patients kept MACE-free after 10 years; after 30 years, more than 20% continued MACE-uneventful, approximately 50% were alive and about 45% were free from re-intervention.
Considering patients submitted to surgical re-intervention, 9 underwent MV valvuloplasty and the others MV replacement with mechanical (32) or biological prothesis (11). At the same procedure, 23 patients were submitted to tricuspid annuloplasty, 9 to other valve replacement and one to coronary artery bypass graft.
Using Cox regression, we found that the presence of moderate disease of other valves at PMC time was associated with a 2.3-fold greater rate of re-intervention compared to patients with none or mid disease of other valves (HRcrude 2.3; 95% IC 1.221–4.331, p=0.017). After adjusting for the success of the PMC and for mitral regurgitation after PMC, the observed effect remained significant (HRadjusted = 2.7; 95% CI 1.417–5.233, p=0.003).
Conclusion
PMC was safe and effective in clinically significant rheumatic MS. Most of the patients were free from adverse events after 10 years and half were alive after 30 years. Still, about 40% required re-intervention, with moderate disease of other valves as its independent predictor.

Introduction
The first-line evaluation of aortic stenosis (AS) severity is Doppler echocardiography. Aortic valvular calcium score (AVCS) measured by tomography scans (TS) is useful in patients for whom echocardiography is not conclusive. For high-risk patients with symptomatic severe AS, transcatheter aortic valve implantation (TAVI) is an established procedure of treatment. The burden of aortic valve calcification has been associated with some TAVI related complications. Peri-prothesis leaks (PPL) are an important complication that may compromise TAVI net results and further refinements are required to predict high-risk patients. Purpose: To access if there is an association between aortic valve calcium score and moderate to severe (mod-sev) peri-prothesis leaks immediately and 6 month after TAVI. Methods: We performed a single-center, retrospective cohort study including patients who underwent TAVI with a preoperative standardised TS with AVCS available. Clinical and echocardiographic data were collected previously to TAVI (pre-TAVI) and at 6 months follow up (6M-FUP). Results: A total of 187 patients were included, with 54% female and a mean age of 79.37± 9.029 year-old. Most patients had tricuspid aortic valve (95.7%); 5 patients had aortic bicuspidy and 3 had aortic valve bioprothesis. Considering left ventricular systolic function, the majority had conserved function (73.0%), the remaining had mild (9.7%), moderate (11.4%) or severe (5.9%) dysfunction. Concerning the valve type, 73.3% had new generation prosthesis and the main valve used was the CoreValve Evolut Pro (33.7%). Also, 38.5% patients underwent balloon valve pre-dilation before implantation. In-hospital mortality was 2.7%. At 6M-FUP, 8 of 182 patients had dead. The mean AVCS was 2851 ± 1524 AU (Agaston Units); 81.2% of women had AVCS > 1300 AU and 74.4% men had AVCS >2000 AU. Comparing AVCS with the presence or absence of moderate to severe peri-prothesis leaks, no statistically significant difference was found immediately (no vs mod-sev leak, AS: 2758 ± 2308 vs 3621 ± 1376, p= 0,13) and 6 months after the procedure (no vs mod-sev leak, AS: 2892 ± 2366 vs 3621 ± 1424, p = 0.15). Considering earlier (Portico, CoreValve Evolut R) vs newer valves (CoreValve Evolut Pro; Edward Sapiens 3; Accurate Neo), there was no statistically significant difference relating AVCS and PPL; however, in patients who had newer valves there was a trend to higher AVCS and moderate to severe leaks, both on the immediate (no vs mod-sev leak, AS: 2777 ± 2507 vs 3601 ± 1385, p = 0.07) and at 6 months (no vs mod-sev leak, AS: 2782 ± 2506 vs 3984 ± 1138, p = 0.06). No statistically significant difference was found when comparing pre-ballooning dilatation. Conclusion: Aortic calcium measured by Agatston score did not show an association with new moderate to severe peri-valvular leaks after TAVI. Nevertheless, it seems to be a trend for higher AS and moderate to severe peri-prothesis leaks when newer valves are implanted.

Introduction
Adults with repaired aortic coarctation (CoA) require lifelong follow-up due to late complications, including left ventricular (LV) myocardial dysfunction. Age at the time of CoA repair is an important prognostic factor in these patients (pts).
Purpose
To evaluate LV size, ejection fraction (EF) and global longitudinal strain (GLS) values using 2D speckle tracking echocardiography (STE) in a population of adult pts with repaired CoA and to assess the relationship between these echocardiographic parameters and age at the time of CoA repair.
Methods
Retrospective analysis of adult pts with repaired CoA, followed in a Grown Up Congenital Heart Disease Centre. Pts with hemodynamically significant concomitant cardiac lesions were ruled out. Epidemiologic and clinical data were obtained from clinical records. Transthoracic echocardiograms were reviewed in order to assess GLS using 2DSTE (Echopac Software, GE).
Results
The study population consisted of 63 pts (61.9% male), with a mean age of 35.3 years at the time of the echocardiographic evaluation. The mean age at the time of the CoA repair was 117 months (95% CI 89.8-144.1 months).
Surgical repair was performed in 46 pts (73%): resection with subclavian artery flap aortoplasty (n = 21); patch aortoplasty (n = 15) and head-to-head anastomosis (n = 10). In 10 pts there was no data regarding the type of surgical repair. Seven pts (11.1%) were submitted to percutaneous intervention (6 with aortic stent implantation and 1 with balloon aortic angioplasty).
Mean LVEF was 63.4% (CI 95% 55.6 – 71.2%) and mean LV end-diastolic diameter (LVEDD) was 50mm (CI 95% 43-57mm). Mean GLS was - 17.3 (CI 95% 14.8- 19.8), which is inferior to the mean normal values reported for the software used.
Age at the time of CoA repair had a statistically significant positive linear relationship with LVEDD (r= 0.282; p= 0.026) and a linear negative relationship with both GLS (r= -0,29; p= 0.022) and LVEF (r= -0.33; p= 0.05).
Conclusion
Older age at the time of CoA repair was associated with increased LVEDD and decreased GLS and LVEF. Also, GLS may be an important tool for the identification of subclinical LV dysfunction in adult pts with repaired CoA.

Abstract
We present a case of a 57-year-old male with previously known primary severe mitral regurgitation, who was admitted to the ICU due to massive venous thromboembolism with associated right ventricle dysfunction and with two large mobile right atrial thrombi (2.4 x 1.5 cm and 3.6 x 3.7 cm). Despite of five days with a therapeutic aPTT achieved with unfractionated heparin (UFH), a TTE showed deterioration of the right ventricle systolic function, persistence of the right atrial masses with similar dimensions together with new mobile thrombi on the coronary sinus and on the right pulmonary artery. Due to deterioration of his clinical condition and given the refractoriness to the classical treatment with UFH, it was decided to administer an ultra-slow low-dose thrombolysis protocol, which consisted in a 24-hour infusion of 24 mg of alteplase at a rate of 1 mg per hour, without bolus. The treatment was continued by 48 consecutive hours, with clinical improvement and important reduction of the right atrial masses with resolution of the coronary sinus and right pulmonary artery thrombi. The patient started hypocoagulation with warfarin bridging with low molecular weight heparin (LMWH). Seven days after alteplase discontinuation there was complete resolution of the intracardiac thrombi. One month after ICU admission a successful mitral valve replacement surgery was conducted. Three months after discharge, the patient is in functional New York Heart Association (NYHA) class I with no cardiovascular events or hospitalizations. This case demonstrates that ultra-slow low-dose thrombolysis is a valid bailout treatment option in patients with large intracardiac thrombi refractory to anticoagulation.

Abstract
Hirsutism is a common condition, being present in about 5–15% of women. It is characterized by the growth of terminal hair in a pattern typical for men, like as hair growth in upper lip, chin, cheek and lower and upper abdomen. Not infrequently, hirsutism is followed by other signs of hyerandrogenism such as alopecia, acne, and seborrhea. The current study evaluated the association between a self-reported history of hirsutism and oligo-amenorrhea during reproductive age and the presence of several comorbidities in women after menopause. A total of 1057 women were investigated in a cross-sectional study, and information on the age at menarche, menstrual history, complaints about excessive hair growth, and disease development was obtained. Participants from the study were postmenopausal women aged >55 y who attended ac primary care service at least once during the 24-month period. Exclusion criteria included the presence of cognitive impairment and/or communication difficulties. Main outcomes were the presence of comorbidities after menopause. The prevalence of comorbidities was significantly higher in women with a history of hirsutism and/or oligo-amenorrhea [OR = 1.6 (95% CI 1.1–2.4), p = 0.002] or isolated hirsutism [OR 2.0 (95% CI 1.3–3.2), p = 0.004]. The prevalence of stroke, angina or myocardial infarction, cardiac failure, chronic obstructive pulmonary disease, and osteoarthritis were significantly higher in postmenopausal women who had experienced hirsutism and/or oligomenorrhea (p < 0.03). Limitations of the study came from the absence of a clear differentiation between hirsutism and hypertrichosis. According our results, the presence of hirsutism and oligo-amenorrhea during the female reproductive period may indicate susceptibility to important diseases at old age.

Abstract
In Brazil there are few reports on the prevalence of anti-Neospora caninum antibodies in dogs from urban, periurban and rural areas. Serum samples from 450 dogs, 300 from urban, 58 from periurban and 92 from rural areas, were tested for the detection of anti-N. caninum IgG antibodies using IFAT: indirect fluorescent antibody test (IFAT, > or =50). Antibodies were observed in 63 (14%) of the 450 serum samples analyzed, with 32 (10.7%) in dogs coming from the urban area, 11 (18.9%) from the periurban area and 20 (21.7%) from the rural area. Statistical differences were seen between the occurrences in animals from the urban area and those of the rural area (P = 0.01). The antibody titers found were: 1:50 in 20 dogs, 1:100-1:800 in 41 dogs, and 1:3200 in two dogs. In the female dogs, a smaller prevalence of dogs with antibodies was observed in those from the urban area (7.5%) in comparison with those of the rural (21.0%) (P = 0.05) and periurban (23.3%) (P = 0.01) areas. There were growing levels of antibody prevalence with the increase in age of the dogs in all three areas studied. Although this increase was not significant, it indicates a tendency towards more infections with age, suggesting post-natal exposure to N. caninum. However, a significant difference (P = 0.05) was observed in the occurrence of anti-N. caninum antibodies in dogs with ages = 2 years in urban (13.1% urban) versus rural environments (27.1% rural). Among the other age brackets studied the difference was not significant. The results confirm the presence of N. caninum in the region and reveal the important role of dogs in the parasite's epidemiology.

Abstract
OBJECTIVE To develop a scoring system for screening children for tuberculosis (TB) and for selecting suspects for further investigation in tuberculosis control programmes. Application of the score model, which would not require sophisticated or expensive technology, would be directed towards resource-poor countries with high prevalences of tuberculosis, where health care workers have to deal with diagnostic problems away from district hospitals or diagnostic facilities. DESIGN Based on contributions from members of an IUATLD task group from 10 countries on the use of diagnostic criteria in childhood tuberculosis, criteria were selected to be used as elements in a score model. Data were collected by standardised questionnaire on 879 subjects aged under 15 years. Of these, 794 were considered probable or confirmed cases of tuberculosis by the diagnosing doctors. From each record, the criteria/procedures used in the diagnosis of probable/confirmed TB and regarded by the doctors as relevant criteria were selected. Bacteriology, histology and chest radiography were used either singly or collectively as the definitive reference (gold standard) against which the more subjective criteria (symptoms, clinical signs, skin test) would be evaluated. The latter criteria cited as relevant were then ranked and further explored for inclusion in the score model. The relative importance of each criterion to every other criterion on the list was expressed as weights, determined by employing a logarithmic least squares method to solve the ratio scale estimation problem which underlies decision-making involving more than one criterion. The resultant values were then assigned to each criterion in the final score model. RESULTS The five clinical criteria thought to be most relevant as predictors of disease in children were history of contact with a case of tuberculosis, positive skin test, persistent cough, low weight for age, and unexplained/prolonged fever. In selecting the optimal cut-off points for the model at which tuberculosis would be suspected, low sensitivity and specificity (below 70%) but reasonably good positive predictive values (60%-77%) were obtained, depending on age group and epidemiological setting. In low tuberculosis prevalence settings, heavy reliance is placed by the model on a history of contact with a household case of tuberculosis and on a positive skin test, both of which have to be true. For high prevalence settings, more or less equal weighting is assigned to all five elements. Case contact and skin tests are less important, with low body weight, prolonged fever and cough being more indicative of tuberculosis. CONCLUSION The model provides for epidemiological differences between target populations and should prove successful as a screening tool to select children for further investigation by radiography and bacteriology.

Abstract
The only schistosome species found in stool specimens in the local population of the republic of São Tomé is Schistosoma intercalatum. An initial survey of schoolchildren showed an overall prevalence of 10.9%, with some schools reaching 29%. No S. haematobium egg was found in 782 urine specimens from the local population, although some were seen in the urine of Angolan soldiers stationed near the capital city. One village in the endemic area, San Marçal, had an S. intercalatum prevalence of 43%, with 14 persons > 40 years of age harbouring severe infections. The transmission area is restricted to the north-east of the main island, where 5 foci apparently account for most of the infections. Seven cases recorded from Principe may be explained by the fact that the children were attending school at São Tomé. Women carrying out domestic activities are more at risk of contracting the infection because of longer periods of water contact than men. The morbidity produced by the infection is restricted to splenomegaly and blood in the stools. High prevalences have been found of Ascaris lumbricoides and Trichuris trichiura, and hookworm and Stronglyloides stercoralis were also observed. Praziquantel was well tolerated and appears to be a good tool for control purposes, although reinfection in the transmission area apparently occurs rapidly. Control strategies based on chemotherapy should take into account an older age group as well as the schoolchildren. Focal mollusciciding and the introduction of washing facilities may also have a role to play in control. The possible recent introduction of the infection to the island is discussed.

Abstract
As part of a mass cytologic screening program, cervical scrapings and endocervical/endometrial aspirations were taken from 1,250 women with systemic schistosomiasis. Ova of S. mansoni were found associated with two cases of carcinoma in situ and one case of invasive squamous cell carcinoma of the uterine cervix. In a fourth case, the ova were associated with a benign cervical lesion.
