RESUMEN

HIV infection causes a constant activation of the immune system and contributes to an enhanced systemic pro-inflammatory cytokine milieu, which has been associated with premature aging and frailty. We performed a systematic review and meta-analysis to analyze whether the HIV-1 RNA load, CD4+ T-lymphocyte counts and exposure to HAART in HIV-positive subjects are associated with frailty phenotype. Searches were performed in PubMed, SCOPUS, Lilacs, Web of Science, Google Scholar, and OpenThesis databases. We used the odds ratio as a measure of the association. We used either a fixed or random-effects model to pool the results of individual studies depending on the presence of heterogeneity. Eleven studies were included in the review. Data from 8035 HIV-positive subjects were analyzed; 2413 of the subjects had viral load detectable, 981 had a CD4T-cell count <350 cells/µL, and 1342 had HAART exposure information. We found an association between frailty and CD4T-cell count <350 cells/µL (OR 2.68, CI 95% 1.68-4.26, I2 = 46%), HIV-1 RNA load detectable (OR 1.71, CI 95% 1.38-2.12, I2 = 0%), and protease inhibitor-containing HAART regimen (OR 2.21, CI 95% 1.26-3.89, I2 = 0%). Further studies are necessary to evaluate the effects of other factors on the development of clinical features related to frailty.

RESUMEN

OBJECTIVE: The aim of this study was to investigate oral and maxillofacial outcomes in children with congenital Zika syndrome (CZS) and the presence of nonnutritive sucking habits, functional habits, and features related to breastfeeding and nutrition of these children. STUDY DESIGN: We conducted a cross-sectional study with 45 children with CZS and 50 healthy controls in Sergipe state, Brazil, from February 2018 to June 2018. Demographic and clinical data, including breastfeeding and feeding data, were obtained for each child. Additionally, oral and maxillofacial evaluation was performed. RESULTS: Low weight (prevalence rate [PR] 8.33; 95% confidence interval [CI] 2.02-34.45), nonexclusive breastfeeding up to 6 months (PR 1.56; 95% CI 1.18-2.08); mouth breathing (PR 3.46; 95% CI 1.83-6.52); difficulty in swallowing (PR 6.00; 95% CI 2.53-14.25); and excessive salivation (PR 4.81; 95% CI 2.18-10.62) were more frequent in children with CZS. Children with CZS were more likely to have abnormal insertion of the upper labial frenulum (PR 7.04; 95% CI 2.23-22.20); ogival palate (PR 3.70; 95% CI 1.63-8.40), dental enamel defects (PR 2.22; 95% CI 1.05-4.69); and delayed dental eruption (PR 8.89; 95% CI 1.16-68.32) compared with healthy children. CONCLUSIONS: Children with CZS had a higher frequency of problems related to breastfeeding, low weight, and oral and maxillofacial abnormalities compared with healthy children.

RESUMEN

Telomere shortening has been proposed as a potentially useful biomarker of human ageing and age-related morbidity and mortality. We performed a systematic review and meta-analysis to summarize results from individual studies on the telomere length according to the frailty status and frailty index in older adults. We searched the PubMed, SCOPUS and Web of Science databases to identify studies that evaluated the telomere length in frail and non-frail older adults and the relationship between telomere length and frailty index score. We used the base pairs (bp) as a measure of the telomere length. Summary estimates were calculated using random-effects models. Nine studies were included in the present systematic review and a total of 10,079 older adults were analyzed. We found that the frail older adults (n = 355) had shorter telomeres than the non-frail (n = 1894) (Standardized Mean Difference [SMD] -0.41; 95% CI -0.73 to -0.09; P = 0.01; I2 = 82%). Significant differences in telomere length between frail and non-frail older adults were identified in Hispanic (SMD -1.31; 95% CI -1.71 to -0.92; P < 0.0001; I2 = 0%) but not in Non-Hispanic countries (SMD -0.13; 95% CI -0.26 to 0.00; P = 0.06; I2 = 0%). Similar results were found in the adjusted meta-analysis (SMD -0.56; 95% -1.12 to 0.00; P = 0.05; I2 = 85%). A significant but weak relationship was found between telomere length and frailty index analyzing 8244 individuals (SMD -0.06; 95% IC -0.10 to 0.01; P = 0.01; I2 = 0%). The current available evidence suggests that telomere length may be not a meaningful biomarker for frailty. Because the potential influence of ethnicity in shortening of telomeres and decline in physiologic reserves associated with aging, additional multiethnic studies are needed.

RESUMEN

Frailty is an emerging geriatric syndrome characterized by decreased physiologic reserve and increased vulnerability to environmental factors. Several studies have examined the association between persistent cytomegalovirus (CMV) infection and poor clinical outcomes in the elderly, but the results are often contradictory. Here, we performed a systematic review and meta-analysis to analyze the association between human herpesvirus seropositivity [CMV, Epstein-Barr virus (EBV), Varicella zoster virus (VZV), and Herpes simplex virus (HSV)] and frailty in elderly people. Searches were performed in PubMed, SCOPUS, Lilacs, IBECS, and Web of Science databases. We used the odds ratio (OR) as a measure of the association between herpesvirus infections and frailty. Summary estimates were calculated using random-effects models. Six studies were included in the present systematic review. The data from 2559 elderly subjects were analyzed; 1571 of the subjects had ages between 60 and 79 years, and 988 of the subjects were older than 80. We found an association between CMV seropositivity and frailty in the elderly aged 60-79 years (OR 2.33, CI 95% 1.48-3.67) but not in the oldest-old subjects (OR 0.67, CI 95% 0.42-1.05). Moreover, no association was found between EBV, VZV, and HSV infections and frailty. Current evidence suggests an association between CMV seropositivity and frailty in individuals aged 60-79 years old.

RESUMEN

Importance: Evidence has emerged on the efficacy of tranexamic acid to control blood loss and postoperative complications after rhinoplasty. Objective: To investigate the results of tranexamic acid use to reduce intraoperative bleeding, postoperative eyelid edema, and periorbital ecchymosis in rhinoplasty. Data Sources and Study Selection: For this systematic review of randomized clinical trials, searches were performed in PubMed, Cochrane Central Register of Controlled Trials, Web of Science, SCOPUS, Science Direct, Google Scholar, OpenThesis, and ClinicalTrials.gov from inception to December 23, 2017. Key words included tranexamic acid, rhinoplasty, and nasal surgical procedures. The following elements were used to define eligibility criteria: (1) population: patients undergoing rhinoplasty surgery; (2) intervention and controls: tranexamic acid vs placebo solution or no-treatment control group; (3) outcomes: intraoperative bleeding, postoperative eyelid edema and periorbital ecchymosis, and thromboembolic events; and (4) study type: randomized clinical trials. Data Extraction and Synthesis: Two reviewers extracted data and assessed study quality according to the Cochrane guidelines for randomized clinical trials. Treatment effects were defined as weighted mean difference (WMD) and 95% CIs. The strength of evidence was analyzed using the Grading of Recommendations Assessment, Development, and Evaluation rating system. Main Outcomes and Measures: Intraoperative bleeding, postoperative eyelid edema and periorbital ecchymosis. To calculate the effect sizes, means and SDs were obtained for each study group and outcome of interest. Results: Five studies comprising 276 patients were included in the systematic review: 177 patients (64.1%) were women, and mean age was 26.8 (range, 16-42) years. Four studies comprising 246 patients estimated the amount in intraoperative bleeding as a primary outcome and were included in the meta-analysis. Eyelid edema and ecchymosis were evaluated as outcomes in 2 studies. Tranexamic acid was associated with reduced bleeding during rhinoplasty was found (WMD, -42.28 mL; 95% CI, -70.36 to -14.21 mL), with differences (P = .01) between oral (WMD, -61.70 mL; 95% CI, -83.02 to -40.39 mL; I2 = 0%) and intravenous (WMD, -23.88 mL; 95% CI, -45.19 to -2.58 mL; I2 = 56%) administration. Eyelid edema and ecchymosis scores in patients receiving tranexamic acid were significantly lower compared with the control group within the first postoperative week: lower eyelid edema, WMD, -0.76; 95% CI, -1.04 to -0.49 and lower eyelid ecchymosis, WMD, -0.94; 95% CI, -1.80 to -0.08. No cases of thromboembolic events were reported. Conclusions and Relevance: Current available evidence suggests that preoperative administration of tranexamic acid is safe and may reduce intraoperative bleeding as well as postoperative eyelid edema and ecchymosis in patients undergoing rhinoplasty.

RESUMEN

In this information epidemiology (infodemiology) study, we describe the online public interest about the issue of femicide in Brazil and analyze the relationship between search queries and femicide trends from 2004 to 2015. We showed that information-seeking behavior for femicide in the Brazilian states has been strongly influenced by female homicide rates. Educational and policy-related interventions are needed to improve the population's knowledge and attitude toward femicide.

RESUMEN

Os autores desenvolveram uma técnica própria de osteotomia frontal supracondiliana do fêmur em "V", no perfil, com fixaçäo interna lateral, usando parafuso deslizante e placa-tubo de 90- (BCD), para correçäo de deformidade em valgo do joelho. Essa técnica foi empregada em pacientes portadores de gonartrose unicompartimental lateral resultante de geno valgo acentuado. Foram avaliados os resultados com o uso dessa técnica em 11 pacientes operados no período de maio de 1984 a abril de 1990, com seguimento pós-operatório médio de três anos e seis meses. Os crotérios de avaliaçäo foram correçäo da deformidade, alívio da dor e mobilidade articular
