Background: The prevalence of thoracic aortic aneurysms (TAA) in patients with known abdominal aortic aneurysms (AAA) is not well known and understudied. Our aim was to conduct a systematic review and meta‐analysis of the overall prevalence of synchronous and metachronous TAA (SM‐TAA) in patients with a known AAA and to understand the characteristics of this sub‐population. Methods and Results: We searched MEDLINE, EMBASE, and CENTRAL (Cochrane Central Register of Controlled Trials) from inception to November 2019 for all population‐based studies reporting on the prevalence of SM‐TAAs in a cohort of patients with AAA. Article screening and data extraction were performed by 2 authors and data were pooled using a random‐effects model of proportions using Freeman‐Tukey double arcsine transformation. The main outcome was the prevalence of SM‐TAAs in patients with AAAs. Secondary outcomes were the prevalence of synchronous TAAs, metachronous TAAs, prevalence of TAAs in patients with AAA according to the anatomic location (ascending, arch, and descending) and the differences in prevalence of these aneurysms according to sex and risk factors. Six studies were included. The pooled‐prevalence of SM‐TAA in AAA patients was 19.2% (95% CI, 12.3–27.3). Results revealed that 15.2% (95% CI, 7.1–25.6) of men and 30.7% (95% CI, 25.2–36.5) of women with AAA had an SM‐TAA. Women with AAA had a 2‐fold increased risk of having an SM‐TAA than men (relative risk [RRs], 2.16; 95% CI, 1.32–3.55). Diabetes mellitus was associated with a 43% decreased risk of having SM‐TAA (RRs, 0.57; 95% CI, 0.41–0.80). Conclusions: Since a fifth of AAA patients will have an SM‐TAA, routine screening of SM‐TAA and their clinical impact should be more thoroughly studied in patients with known AAA.

Background:Diplopia is a symptom with very different etiologies. It may be caused by pathology in the eye, orbit, extraocular muscles, neuromuscular junction, or in the central nervous system. Case Report:Three clinical cases of hospitalization due t...

Growing information has emphasized the risk of benzodiazepines (BZD), particularly among the elderly. However, the information available in Latin America is scarce. to review the available information on the use of BZD in older adults in Latin America to achieve an overview of the information currently available, and a thorough understanding of this phenomenon in our region. A systematic review with MeSH terms “elderly”, “latinamerican” and “benzodiazepines” was performed in PubMed and with each Latin American country. A search in databases SciELO and LILACS was also performed. In all, 126 items of finally selected 21 that met the inclusion criteria. Studies show that consumption of benzodiazepines in the elderly population in Latin America is high, with a preponderance of long half-life benzodiazepines in women, and frequent self-medication. The revised articles establish the importance of further study of the phenomenon of the use of benzodiazepines in our elderly population. Strikingly, scientific information is scarce, with most studies coming from only one country (Brazil). Moreover, most of them are transversal and descriptive, with few studies that explore long-term side effects, or specific hypotheses. Further studies should address these important issues.
