Risk factors for human papillomavirus infection among women in Portugal: the CLEOPATRE Portugal Study

OBJECTIVE: To investigate demographic, socioeconomic, lifestyle, and medical factors that might predispose women to cervical human papillomavirus (HPV) infection. METHOD: A cross-sectional population-based study was performed. Women aged 18-64 years who attended selected obstetrics and gynecology or sexually transmitted disease (STD) clinics in mainland Portugal between February 2008 and March 2009 were recruited, according to an age-stratified sampling strategy. Liquid-based cytology samples were analyzed centrally for HPV genotype and for cytologic features. Univariate and multivariate logistic regression analyses identified risk factors for HPV infection. RESULTS: Among the 2326 women evaluated, the crude prevalence of HPV infection was 19.4%. Lifetime number of sexual partners was a strong predictor of HPV infection (odds ratio 5.44 for 5-10 partners versus 1 partner; P<0.001). Other risk factors were young age (particularly among women aged 20-24 years; P<0.001); country of birth other than mainland Portugal (P=0.002); education up to secondary school level (P=0.010); smoking history (≤ 10 years; P=0.004); and any STD in the past 12 months (P=0.052). CONCLUSION: Data from the present study may aid identification of women at increased risk of HPV infection and target prevention strategies.

Pediatric Organ and Tissue Donation—A 10-Year Retrospective Study in Portugal

Organ and tissue donation can transform lives. One donor can ensure the survival of up to 8 people through their organs and improve the quality of life for dozens more through tissue donation. Portugal has an excellent transplantation rate, but deaths still occur while waiting for an organ. The study aimed to analyze pediatric organ and tissue donors nationally and evaluate brain deaths in a pediatric intensive care unit (PICU) over the past 10 years to identify any potential lost donors. We conducted a retrospective descriptive study of pediatric organ and tissue donors and diagnosed brain deaths from January 2011 to December 2021. Demographic and clinical data were analyzed, including those provided by the National Transplant Coordination. Over the past 10 years in Portugal, 121 pediatric donors (11.7 per million population) were collected, and 569 organs and tissues were collected. During the same period in the PICU, there were 125 deaths, including 20 brain deaths. Of this group, 4 were organ and tissue donors. In the non-donor group (n = 16), a potential lost donor case stands out. Pediatric specialists need to be more familiar with the donation process, which would enable the identification and optimization of all potential donors, thus minimizing the number of potentially lost organs.info:eu-repo/semantics/publishedVersio

Coronary artery bypass surgery without cardioplegia: hospital results in 8515 patients†

OBJECTIVES: Cardioplegic myocardial protection is used in most cardiac surgical procedures. However, other alternatives have proved useful. We analysed the perioperative results in a large series of patients undergoing coronary artery bypass (CABG) using cardiopulmonary bypass (CPB) and non-cardioplegic methods. METHODS: From January 1992 to October 2013, 8515 consecutive patients underwent isolated CABG with CPB without cardioplegia, under hypothermic ventricular fibrillation and/or an empty beating heart. The mean age was 61.9 ± 9.5 years, 12.4% were women, 26.3% diabetic, 64% hypertensive; and 9.6% had peripheral vascular disease, 7.8% cerebrovascular disease and 54.3% previous acute myocardial infarction (AMI). One-third of patients were in Canadian Cardiovascular Society Class III/IV. Three-vessel disease was present in 76.5% of the cases and 10.9% had moderate/severe left ventricle (LV) dysfunction (ejection fraction <40%). A multivariate analysis was made of risk factors associated to in-hospital mortality and three major morbidity complications [cerebrovascular accident, mediastinitis and acute kidney injury (AKI)], as well as for prolonged hospital stay. RESULTS: The mean CPB time was 58.2 ± 20.7 min. The mean number of grafts per patient was 2.7 ± 0.8 (arterial: 1.2 ± 0.5). The left internal thoracic artery (ITA) was used in 99.4% of patients and both ITAs in 23.1%. The in-hospital mortality rate was 0.7% (61 patients), inotropic support was required in 6.6% and mechanical support in 0.8, and 2.0% were re-explored for bleeding and 1.3% for sternal complications (mediastinitis, 0.8%). AKI, the majority transient, occurred in 1595 patients (18.9%). The incidence rates of stroke/transient ischemic attack (TIA) and acute myocardial infarction (AMI) were 2.6 and 2.5%, respectively, and atrial fibrillation/flutter occurred in 22.6% of cases. Age, LV dysfunction, non-elective surgery, previous cardiac surgery, peripheral vascular disease and CPB time were independent risk factors for mortality and major morbidity. The mean hospital stay was 7.2 ± 5.7 days. CONCLUSIONS: Isolated CABG with CPB using non-cardioplegic methods proved very safe, with low mortality and morbidity. These methods are simple and expeditious and remain as very useful alternative techniques of myocardial preservation.info:eu-repo/semantics/publishedVersio

Using patient-reported outcome measures to evaluate care for patients with inflammatory chronic rheumatic disease

Objectives: Few countries integrate Patient-Reported Outcome Measures (PROMs) in routine performance assessment, and those that do focus on elective surgery. This study addresses the challenges of using PROMs to evaluate care in chronic conditions. We set out a modelling strategy to assess the extent to which changes over time in self-reported health status by patients with inflammatory chronic rheumatic disease are related to their biological drug therapy and Rheumatology centre primarily responsible for their care. Methods: Using data from the Portuguese Register of Rheumatic Diseases, we assess the health status using the Health Assessment Questionnaire-Disability Index (HAQ-DI) for rheumatic patients receiving biological drugs between 2000 and 2017. We employ a fixed effects model using the Least Squares Dummy Variables estimator. Results: Patients receiving infliximab or rituximab report lower health status than those on etanercept (the most common therapy) and patients in 4 of the 26 Rheumatology centres report higher health status than those at other centres. Conclusions: PROMs can be used for those with chronic conditions to provide the patient’s perspective about the impact on their health status of the choice of drug therapy and care provider. Care for chronic patients might be improved if healthcare organisations monitor PROMs and engage in performance assessment initiatives on a routine basis

Composition and screening of antifungal activity against Cladosporium sphaerospermum and Cladosporium cladosporioides of essential oils of leaves and fruits of Piper species

This study investigated the composition and antifungal activity against Cladosporium sphaerospermum and Cladosporium cladosporioides of essential oils of leaves of Piper cernuum, Piper diospyrifolium, Piper crassinervium, Piper solmsianum and Piper umbelata and fruits of P. cernuum and P. diospyrifolium. The essentials oils were analyzed by GC-MS and submitted of the antifungal activity tests. The essential oils of fruits from P. cernuum and leaves of P. crassinervium and P. solmsianum showed potential antifungal activity against C. sphaerospermum and C. cladosporioides. In addition, this is the first report of the composition of essential oils of fruits of P. cernuum and P. diospyrifolium.Key words: Piperaceae, Piper; essential oil composition, antifungal activity, GC-MS

A genome-wide linkage and association scan reveals novel loci for autism

Although autism is a highly heritable neurodevelopmental disorder, attempts to identify specific susceptibility genes have thus far met with limited success. Genome-wide association studies using half a million or more markers, particularly those with very large sample sizes achieved through meta-analysis, have shown great success in mapping genes for other complex genetic traits. Consequently, we initiated a linkage and association mapping study using half a million genome-wide single nucleotide polymorphisms (SNPs) in a common set of 1,031 multiplex autism families (1,553 affected offspring). We identified regions of suggestive and significant linkage on chromosomes 6q27 and 20p13, respectively. Initial analysis did not yield genome-wide significant associations; however, genotyping of top hits in additional families revealed an SNP on chromosome 5p15 (between SEMA5A and TAS2R1) that was significantly associated with autism (P = 2 x 10(-7)). We also demonstrated that expression of SEMA5A is reduced in brains from autistic patients, further implicating SEMA5A as an autism susceptibility gene. The linkage regions reported here provide targets for rare variation screening whereas the discovery of a single novel association demonstrates the action of common variants

Trends and challenges in the Portuguese penitentiary system: from law to practice

This article focuses on the trends and challenges faced by the Portuguese penitentiary system between 2000 and 2017, taking into account the Portuguese Penal Law, penal statistics, national and international reports, and studies regarding the Portuguese prison system. The description of the changes in the Penal Law helps us to understand, on one hand, the changes in penal statistics over time and, on the other hand, the inconsistencies between the law in books and law in practice

Polimiosite : investigação clínica em duas irmãs

We present an investigation of a case of polymyositis affecting two sisters of one same parenthood. Their cases have been documented for almost two decades, being investigated by means of a diagnostic protocol which combined clinical findings as well as laboratorial, histopathological and image tests. In both cases, clinical manifestations started in childhood, without signs of involvement of the central and peripheral nervous system. Both patients proved to respond to a therapeutics based on corticosteroids. The degree of relatedness between their parents corroborate the notion that genetic factors may contribute to the development of the disease. ___________________________________________________________________________________________________ RESUMOApresentamos a investigação de dois casos de polimiosite, ocorridos entre irmãs de uma mesma filiação. Seus casos foram documentados ao longo de quase duas décadas, tendo sido diagnosticados utilizando- se de protocolo diagnóstico que combinou achados clínicos, exames laboratoriais, histopatológicos e por imagem. Em ambos os casos, as manifestações clínicas se iniciaram ainda na infância, sendo constatada ausência de acometimento do sistema nervoso central ou periférico. Ambas as pacientes responderam satisfatoriamente a terapia baseada em corticosteróide. O grau de parentesco entre os genitores das pacientes sugere que fatores genéticos podem predispor ao desenvolvimento da doença
