Background: Human immunodeficiency virus (HIV), the agent responsible for acquired immunodeficiency syndrome, remains a worldwide public health problem. Therefore, this study aimed to assess Portuguese healthcare students’ knowledge of HIV, identify risk behaviors for HIV transmission, and assess the frequency of HIV testing and its dissemination by general practitioners. Methods: A cross-sectional observational study was conducted using an anonymous questionnaire published online. The questionnaire was administered to Portuguese healthcare students who voluntarily agreed to participate in the study after clarifying its objectives and procedures. Results: Most students were aware of the three main HIV transmission routes; however, 66.3% were unaware of the level A recommendation for HIV screening in adolescents and adults. In addition, 59.6% of the students were never informed by their general practitioner about HIV screening tests or risk behaviors for HIV transmission. Of the sample, 78.9% had never been tested for HIV infection. Of the 74.6% of sexually active students, 82.0% had or had already had unprotected sex (without a condom). Men showed riskier sexual behaviors than women. None of the inquiries reported intravenous drug use, and most students (69.9%) never shared personal objects. Conclusion General practitioners and awareness campaigns need to alert and disseminate HIV screening tests. Sexual health and risk behaviors should be addressed more frequently in schools to educate this population because prevention is the best strategy against HIV transmission/contraction.

Background: Left ventricular (LV) thrombus has a higher incidence among patients with anterior ST-elevation myocardial infarction (STEMI) when compared to other types of acute myocardial infarction and is associated with worse prognosis. The management of LV thrombus diagnosis remains challenging. Contrast echocardiography (transthoracic echocardiography, TTE) has shown potential in improving the accuracy for its diagnosis, thereby influencing treatment strategies concerning antithrombotic/anticoagulation therapy. The aim of this study was to assess the effectiveness of contrast TTE as a routine screening method for detecting LV thrombus in the acute phase of anterior STEMI. Methods: A prospective, single center, randomized controlled trial was conducted among patients with anterior STEMI. The study group underwent contrast TTE, while the control group received a conventional approach. Demographical, clinical, and diagnostic data were collected. Thrombus detection rates were compared between groups. Results: A total of 68 patients were included (32 in the study group and 36 in the control group). No substantial baseline differences were observed between groups. Thrombus detection rate was 25.0% in the study group and 13.9% in the control group, however these results did not reach statistical significance (P = 0.24). The prevalence of anterior/ apical aneurysm was higher in the study group (46.9% vs. 22.2%, P = 0.03). Conclusions Conventional TTE may be adequate for diagnosing LV thrombus in the acute phase of anterior STEMI; however, further larger-scale and multicenter studies are necessary to obtain more robust and conclusive results. Ultrasound contrast may play a significant role in the detection of anterior/apical aneurysms, which are known risk factors for the subsequent development of thrombus.

Objectives: The aim of this study was to evaluate the profile of patients on antiresorptive therapies for cancer treatment and assess presence of oral lesions, oral hygiene status, and knowledge regarding medication-related osteonecrosis of the jaw (MRONJ). Materials and Methods: This was an observational cross-sectional study that evaluated patients treated with antiresorptive medication at a single cancer hospital. Clinical data were collected and oral examination was performed to assess patient oral health. Results: From July 2017 to December 2018, 90 patients were assessed; 64 were female and 26 were male, and the mean age was 61 years. The most common drug was an intravenous bisphosphonate, zoledronic acid. Among the 90 patients, 47 presented with some type of oral disease, isolated or associated. Among these 47 patients, 9 patients (10%) developed osteonecrosis. Oral hygiene was evaluated, and most patients, with or without MRONJ, presented with regular to poor condition. Regarding patient knowledge of the risks of MRONJ and the risks associated with dental surgery, 60% stated that they were not aware of the risks. Conclusion Identifying the profile of patients and their needs facilitates not only the preventive process, but also the emergence of new therapeutic options. Our study shows that most patients are weakened both by metastatic disease and antineoplastic treatment as well as by issues associated with aging because most were over 60 years of age. Collectively, this information should be considered for management of preventive and therapeutic measures.

Background: and Purpose The incidence of multiple sclerosis (MS) among older patients is increasing. Some of these patients develop the disease after the age of 50 years, a condition known as late-onset MS (LOMS). This study aimed to characterize MS in older patients (50–75 years-old) by comparing LOMS with adult-onset MS (AOMS). Methods: We retrospectively analyzed data from 230 patients aged 50–75 years who attended a Portuguese tertiary referral center. Results: This study included 189 AOMS patients aged 58 [54–63] years (median [interquartile range]) and 41 LOMS patients aged 67 [61–70] years. Females predominated in both the LOMS (70.7%) and AOMS (75.1%) groups. Primary progressive MS was more common in LOMS than AOMS patients (19.5% vs. 8.0%, p=0.03) and these two groups had equivalent proportions of relapsing-remitting MS (53.7% vs. 59.0%, p=0.55). The Expanded Disability Status Scale (EDSS) score at the diagnosis was higher in the LOMS patients (2 [1–4], p=0.03), but the current EDSS score did not differ significantly between the LOMS and AOMS patients (3.5 [1.75–6] vs. 3 [1.5–6], p=0.86). After adjusting or matching for age and disease duration, the current EDSS scores were not significantly different in the two groups. The proportion of patients currently receiving disease-modifying therapies was higher in LOMS patients (97.6%, p=0.02). A higher proportion of patients with a later onset had infratentorial involvement at a 5-year follow-up (86.7%, p=0.01). The time to an EDSS score of 6.0 was shorter for LOMS patients. Conclusions The LOMS patients presented with higher EDSS scores at the diagnosis, reaching a level of disability not significantly different from AOMS patients of the same age group despite a shorter disease course.

Background: Aortic regurgitation (AR) has an important impact on myocardial mechanics and recent studies have proved the value of global longitudinal strain (GLS) in the assessment of its severity and prognosis. Our purpose was to assess if the direct impact of the regurgitant jet on the myocardial wall could affect regional longitudinal strain. Methods: Eighty patients with chronic moderate/severe AR were retrospectively studied. Patients were considered to have a jet-related longitudinal strain reduction when the myocardial segments directly impacted by the jet had their longitudinal strain reduced by at least 30% compared to nonaffected segments. AR severity, left ventricular (LV) size and function were compared according to the presence/absence of this regional pattern. For those who underwent surgery, postoperative regional and global LV function was also analyzed. Results: A pattern of regional longitudinal strain impairment was identified in 43% of patients, with a regional reduction (in median) of 10 percentage points in absolute strain values in the segments impacted by the jet, compared to nonaffected segments. In the subgroup who underwent surgery, this pattern became attenuated after surgery.Patients with regional longitudinal strain impairment were less likely to improve GLS after surgery (10% vs. 38% improved GLS by at least 2.5%, P = 0.049). Conclusions To our knowledge, this study identifies for the first time, a link between the location of the impact of the regurgitant jet in AR and regional longitudinal strain impairment. The presence of this regional pattern might be associated with worse postoperative LV recovery.
