- Correlação entre Espessura Macular e Camada de Fibras Nervosas Peripapilar no Glaucoma InicialPublication . Cabugueira, A; Vicente, A; Lemos, V; Anjos, R; Rosa, R; Flores, R; Gomes, T; Reina, MIntrodução: Os autores pretendem analisar a espessura macular e a camada de fibras nervosas peripapilar (CFN) em doentes com glaucoma inicial e com o diagnóstico de hipertensão ocular (HTO). Também propõem um modelo de correspondência da espessura macular de uma dada região do hemisfério superior com a CFN temporal superior (TS) e do hemisfério inferior com a CFN temporal inferior (TI) no glaucoma inicial. Material e Métodos: Estudo retrospectivo não randomizado, constituído por 48 olhos com glaucoma inicial e 39 olhos com diagnóstico de HTO, submetidos a análise da assimetria da espessura macular do polo posterior e da CFN por Tomografia de coerência óptica Spectral Domain (SD-OCT). Avaliamos a correlação entre a espessura macular de uma região selecionada do hemisfério superior e do inferior, com a CFN TS e TI, respectivamente. Resultados: Nos doentes com glaucoma inicial, a espessura macular e a CFN (global e sectorial) foram significativamente inferiores (p<0,01). A correlação da CFN TS com a espessura macular da região selecionada do hemisfério superior foi moderada (R:0,403; p<0,01), e da CFN TI com a região selecionada do hemisfério inferior foi positiva forte (R:0,612; p<0,001). Conclusão: Dado que, a CFN TI é o sector apontado como precocemente afectado no glaucoma, e se verificou uma correlação forte com a região macular inferior selecionada, consideramos que esta também pode ser mais vulnerável à lesão glaucomatosa inicial. A avaliação desta região isoladamente ou integrada com a CFN, poderá ser valiosa no diagnóstico precoce.

- Surgical Options After Fontan FailurePublication . van Melle, JP; Wolff, D; Hörer, J; Belli, E; Meyns, B; Padalino, M; Lindberg, H; Jacobs, J; Mattila, I; Berggren, H; Berger, R; Prêtre, R; Hazekamp, M; Helvind, M; Nosál, M; Tlaskal, T; Rubay, J; Lazarov, S; Kadner, A; Hraska, V; Fragata, J; Pozzi, M; Sarris, G; Michielon, G; di Carlo, D; Ebels, TOBJECTIVE: The objective of this European multicenter study was to report surgical outcomes of Fontan takedown, Fontan conversion and heart transplantation (HTX) for failing Fontan patients in terms of all-cause mortality and (re-)HTX. METHODS: A retrospective international study was conducted by the European Congenital Heart Surgeons Association among 22 member centres. Outcome of surgery to address failing Fontan was collected in 225 patients among which were patients with Fontan takedown (n=38; 17%), Fontan conversion (n=137; 61%) or HTX (n=50; 22%). RESULTS: The most prevalent indication for failing Fontan surgery was arrhythmia (43.6%), but indications differed across the surgical groups (p<0.001). Fontan takedown was mostly performed in the early postoperative phase after Fontan completion, while Fontan conversion and HTX were mainly treatment options for late failure. Early (30 days) mortality was high for Fontan takedown (ie, 26%). Median follow-up was 5.9 years (range 0-23.7 years). The combined end point mortality/HTX was reached in 44.7% of the Fontan takedown patients, in 26.3% of the Fontan conversion patients and in 34.0% of the HTX patients, respectively (log rank p=0.08). Survival analysis showed no difference between Fontan conversion and HTX (p=0.13), but their ventricular function differed significantly. In patients who underwent Fontan conversion or HTX ventricular systolic dysfunction appeared to be the strongest predictor of mortality or (re-)HTX. Patients with valveless atriopulmonary connection (APC) take more advantage of Fontan conversion than patients with a valve-containing APC (p=0.04). CONCLUSIONS: Takedown surgery for failing Fontan is mostly performed in the early postoperative phase, with a high risk of mortality. There is no difference in survival after Fontan conversion or HTX.
- Peripheral Artery Disease Patients May Benefit More from Aggressive Secondary Prevention than Aneurysm Patients to Improve SurvivalPublication . Ultee, K; Hoeks, Sa; Basto Gonçalves, F; Boersma, E; Stolker, R; Verhagen, H; Rouwet, EBACKGROUND AND AIMS: Although it has become clear that aneurysmal and occlusive arterial disease represent two distinct etiologic entities, it is still unknown whether the two vascular pathologies are prognostically different. We aim to assess the long-term vital prognosis of patients with abdominal aortic aneurysmal disease (AAA) or peripheral artery disease (PAD), focusing on possible differences in survival, prognostic risk profiles and causes of death. METHODS: Patients undergoing elective surgery for isolated AAA or PAD between 2003 and 2011 were retrospectively included. Differences in postoperative survival were determined using Kaplan-Meier and Cox regression analysis. Prognostic risk profiles were also established with Cox regression analysis. RESULTS: 429 and 338 patients were included in the AAA and PAD groups, respectively. AAA patients were older (71.7 vs. 63.3 years, p < 0.001), yet overall survival following surgery did not differ (HR: 1.16, 95% CI: 0.87-1.54). Neither was type of vascular disease associated with postoperative cardiovascular nor cancer-related death. However, in comparison with age- and gender-matched general populations, cardiovascular mortality was higher in PAD than AAA patients (48.3% vs. 17.3%). Survival of AAA and PAD patients was negatively affected by age, history of cancer and renal insufficiency. Additional determinants in the PAD group were diabetes and ischemic heart disease. CONCLUSIONS: Long-term survival after surgery for PAD and AAA is similar. However, overall life expectancy is significantly worse among PAD patients. The contribution of cardiovascular disease towards mortality in PAD patients warrants more aggressive secondary prevention to reduce cardiovascular mortality and improve longevity.
- EULAR Recommendations for Women's Health and the Management of Family Planning, Assisted Reproduction, Pregnancy and Menopause in Patients with Systemic Lupus Erythematosus and/or Antiphospholipid SyndromePublication . Andreoli, L; Bertsias, GK; Agmon-Levin, N; Brown, S; Cervera, R; Costedoat-Chalumeau, N; Doria, A; Fischer-Betz, R; Forger, F; Moraes-Fontes, MF; Khamashta, M; King, J; Lojacono, A; Marchiori, F; Meroni, PL; Mosca, M; Motta, M; Ostensen, M; Pamfil, C; Raio, L; Schneider, M; Svenungsson, E; Tektonidou, M; Yavuz, S; Boumpas, D; Tincani, AOBJECTIVES: Develop recommendations for women's health issues and family planning in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS). METHODS: Systematic review of evidence followed by modified Delphi method to compile questions, elicit expert opinions and reach consensus. RESULTS: Family planning should be discussed as early as possible after diagnosis. Most women can have successful pregnancies and measures can be taken to reduce the risks of adverse maternal or fetal outcomes. Risk stratification includes disease activity, autoantibody profile, previous vascular and pregnancy morbidity, hypertension and the use of drugs (emphasis on benefits from hydroxychloroquine and antiplatelets/anticoagulants). Hormonal contraception and menopause replacement therapy can be used in patients with stable/inactive disease and low risk of thrombosis. Fertility preservation with gonadotropin-releasing hormone analogues should be considered prior to the use of alkylating agents. Assisted reproduction techniques can be safely used in patients with stable/inactive disease; patients with positive antiphospholipid antibodies/APS should receive anticoagulation and/or low-dose aspirin. Assessment of disease activity, renal function and serological markers is important for diagnosing disease flares and monitoring for obstetrical adverse outcomes. Fetal monitoring includes Doppler ultrasonography and fetal biometry, particularly in the third trimester, to screen for placental insufficiency and small for gestational age fetuses. Screening for gynaecological malignancies is similar to the general population, with increased vigilance for cervical premalignant lesions if exposed to immunosuppressive drugs. Human papillomavirus immunisation can be used in women with stable/inactive disease. CONCLUSIONS: Recommendations for women's health issues in SLE and/or APS were developed using an evidence-based approach followed by expert consensus.
- Influence of Remote Monitoring on Long-Term Cardiovascular Outcomes after Cardioverter-Defibrillator ImplantationPublication . Portugal, G; Cunha, PS; Valente, B; Feliciano, J; Lousinha, A; Alves, S; Braz, M; Pimenta, R; Delgado, AS; Oliveira, MM; Cruz Ferreira, RAIMS: Device-based remote monitoring (RM) has been linked to improved clinical outcomes at short to medium-term follow-up. Whether this benefit extends to long-term follow-up is unknown. We sought to assess the effect of device-based RM on long-term clinical outcomes in recipients of implantable cardioverter-defibrillators (ICD). METHODS: We performed a retrospective cohort study of consecutive patients who underwent ICD implantation for primary prevention. RM was initiated with patient consent according to availability of RM hardware at implantation. Patients with concomitant cardiac resynchronization therapy were excluded. Data on hospitalizations, mortality and cause of death were systematically assessed using a nationwide healthcare platform. A Cox proportional hazards model was employed to estimate the effect of RM on mortality and a composite endpoint of cardiovascular mortality and hospital admission due to heart failure (HF). RESULTS: 312 patients were included with a median follow-up of 37.7months (range 1 to 146). 121 patients (38.2%) were under RM since the first outpatient visit post-ICD and 191 were in conventional follow-up. No differences were found regarding age, left ventricular ejection fraction, heart failure etiology or NYHA class at implantation. Patients under RM had higher long-term survival (hazard ratio [HR] 0.50, CI 0.27-0.93, p=0.029) and lower incidence of the composite outcome (HR 0.47, CI 0.27-0.82, p=0.008). After multivariate survival analysis, overall survival was independently associated with younger age, higher LVEF, NYHA class lower than 3 and RM. CONCLUSION: RM was independently associated with increased long-term survival and a lower incidence of a composite endpoint of hospitalization for HF or cardiovascular mortality.
- First-Episode Psychosis in a 15 Year-Old Female with Clinical Presentation of Anti-NMDA Receptor Encephalitis: A Case Report and Review of the LiteraturePublication . Moura, M; Silva-Dos-Santos, A; Afonso, J; Talina, MAnti-NMDA receptor encephalitis is an autoimmune disease that was identified in 2007, and manifests in a stepwise manner with psychiatric, neurological and autonomic symptoms. The disease is caused by autoantibodies against NMDA receptors. It can have a paraneoplastic origin, mainly secondary to ovarian teratomas, but it can also be unrelated to the tumor. This disease can affect both sexes and all ages. CASE PRESENTATION: Here, we present a case of a 15 year-old female adolescent with first-episode psychosis with anti-NMDA receptor encephalitis not related to tumor, which manifested with delusion, hallucinations, panic attacks, agitation, and neurological symptoms, and later with autonomic instability. She was treated with immunotherapy and psychiatric medication resulting in improvement of her main psychiatric and neurological symptoms. CONCLUSION: Our main objective in presenting this case is to alert clinicians to this challenging and recent disease that has a clinical presentation that might resemble a functional psychiatric condition and can be underdiagnosed in the context of child and adolescent psychiatry.
- Acquired Cold Urticaria: Clinical Features, Particular Phenotypes, and Disease Course in a Tertiary Care Center CohortPublication . Deza, G; Brasileiro, A; Bertolín-Colilla, M; Curto-Barredo, L; Pujol, R; Giménez-Arnau, ABACKGROUND: Data about special phenotypes, natural course, and prognostic variables of patients with acquired cold urticaria (ACU) are scarce. OBJECTIVES: We sought to describe the clinical features and disease course of patients with ACU, with special attention paid to particular phenotypes, and to examine possible parameters that could predict the evolution of the disease. METHODS: This study was a retrospective chart review of 74 patients with ACU who visited a tertiary referral center of urticaria between 2005 and 2015. RESULTS: Fourteen patients (18.9%) presented with life-threatening reactions after cold exposure, and 21 (28.4%) showed negative results after cold stimulation tests (classified as atypical ACU). Nineteen patients (25.7%) achieved complete symptoms resolution at the end of the surveillance period and had no subsequent recurrences. Higher rates of atypical ACU along with a lower likelihood of achieving complete symptom resolution was observed in patients who had an onset of symptoms during childhood (P < .05). In patients with atypical ACU, shorter disease duration and lower doses of antihistamines required for achieving disease control were detected (P < .05). Age at disease onset, symptom severity, and cold urticaria threshold values were found to be related to disease evolution (P < .05). LIMITATIONS: This study was limited by its retrospective nature. CONCLUSIONS: The knowledge of the clinical predictors of the disease evolution along with the clinical features of ACU phenotypes would allow for the establishment of an early and proper therapeutic strategy.
