Ideal Cardiovascular Health in Mexican Adults with CKD Living in Mexico City Versus Chicago.

Evidence suggests that Mexican adults living in Mexico have a more favorable cardiovascular risk profile than Mexican adults living in the U.S. However, this relationship has not been evaluated among patients with chronic kidney disease (CKD), which is a question of importance given the high risk for cardiovascular disease among patients with CKD. Using data from two ongoing observational cohort studies, we compared the prevalence of ideal cardiovascular health metrics (assessed by the American Heart Association "Life's Simple 7" criteria) in 309 Mexican adults with CKD living in Mexico City to 343 Mexican adults with CKD living in Chicago. Mexican adults with CKD living in Mexico City had a significantly higher prevalence of ideal body mass index (25 vs. 10%), diet (17 vs. 8%), total cholesterol (80 vs. 63%), blood pressure (43 vs. 25%), and fasting glucose (54 vs. 42%). Mexican adults with CKD living in both Mexico City and Chicago had low levels of cardiovascular health scores. Future work is needed to better understand the lower prevalence of ideal cardiovascular health metrics in Chicago as compared to Mexico City.

Magnetic resonance imaging texture analysis for quantitative evaluation of the mandibular condyle in juvenile idiopathic arthritis.

OBJECTIVES: Juvenile idiopathic arthritis (JIA) is a chronic inflammatory disease that affects the joints and other organs, including the development of the former in a growing child. This study aimed to evaluate the feasibility of texture analysis (TA) based on magnetic resonance imaging (MRI) to provide biomarkers that serve to identify patients likely to progress to temporomandibular joint damage by associating JIA with age, gender and disease onset age. METHODS: The radiological database was retrospectively reviewed. A total of 45 patients were first divided into control group (23) and JIA group (22). TA was performed using grey-level co-occurrence matrix (GLCM) parameters, in which 11 textural parameters were calculated using MaZda software. These 11 parameters were ranked based on the p value obtained with ANOVA and then correlated with age, gender and disease onset age. RESULTS: Significant differences in texture parameters of condyle were demonstrated between JIA group and control group (p < 0.05). There was a progressive loss of uniformity in the grayscale pixels of MRI with an increasing age in JIA group. CONCLUSIONS: MRI TA of the condyle can make it possible to detect the alterations in bone marrow of patients with JIA and promising tool which may help the image analysis.

Dental care for patients with special needs at a private higher education institute / Atendimento odontológico a pacientes com necessidades especiais em uma instituição privada de ensino superior

Objetivo: Pacientes com necessidades especiais são aqueles indivíduos que necessitam de cuidados especiais por tempo indeterminado ou por toda a vida. O presente estudo tem como objetivo abordar o atendimento odontológico de pacientes com necessidades especiais em uma instituição privada de ensino superior da cidade de São Paulo. Material e Métodos: Foi realizado um estudo descritivo, retrospectivo, para análise de 210 prontuários odontológicos de pacientes com necessidades especiais atendidos no Departamento de Odontologia para Pacientes Especiais da Universidade Cruzeiro do Sul entre 2012 e 2018. Dados sobre sexo, idade, diagnóstico da condição debilitante, motivo da consulta, uso continuado de medicamentos, imagens radiográficas e tratamentos odontológicos prestados foram todos coletados e posteriormente submetidos à análise estatística descritiva e inferencial (teste do qui-quadrado) ao nível de significância de 5%. Resultados: Quanto aos tipos de procedimentos odontológicos avaliados no presente estudo, dos 210 pacientes, 24% necessitaram de tratamentos curativos dentários em que a terapia periodontal foi o tipo mais prevalente, enquanto os tratamentos endodônticos tiveram a menor prevalência, representando apenas 4%. Houve alta prevalência de doenças crônicas sistêmicas, acometendo 56% dos casos, cuja faixa etária era superior a 40 anos. Conclusão: Check-ups odontológicos regulares devem ser priorizados em pacientes com necessidades especiais para evitar intervenções mais invasivas como em nosso grupo (AU)

Objective: Patients with special needs are those individuals who need special care for an undetermined period of time or for lifetime. The present study is aimed to address the dental care of special needs patients at a private higher education institute in the city of São Paulo. Material and Methods: A descriptive, retrospective study was performed for analysis of 210 dental records of special needs patients who were treated at the Dental Department for Special Patients of the Cruzeiro do Sul University between 2012 and 2018. Data on gender, age, diagnosis of the debilitating condition, reason of the consultation, continued use of medications, radiographic images and dental treatments provided were all collected before being submitted to descriptive and inferential statistical analysis (chi-square test) at a significance level of 5%. Results: As for the types of dental procedures assessed in the present study, of the 210 patients, 24% needed dental curative treatments in which periodontal therapy was the most prevalent type, whereas endodontic treatments had the lowest prevalence, representing 4% only. There was a high prevalence of chronic systemic diseases, affecting 56% of the dental records, whose age group was above 40 years old. Conclusion: Regular dental check-ups should be prioritized in patients with special needs to avoid more invasive interventions as found in our group (AU)

Three-Dimensional Volumetric Analysis of Frontal Ethmoidal Cells and Evaluation of Influential Factors: A Helical Computed Tomography Study.

In the present study, we aimed to assess frontal ethmoidal cells by using segmentation 3D software to establish a possible correlation between volume variation and both gender and age, as well as a relationship with Keros classification. Helical computed tomography images were obtained from 71 patients for analysis, in which the agger nasi cell, supra agger cell, supra agger frontal cell, supra bulla frontal cell, supraorbital ethmoidal cell, supra bulla cell, and frontal septal cell were identified and segmented to obtain their volume. Significant differences in volume were found for age and gender regarding agger nasi cells (p-value = 0.017), supra agger cells (p-value < 0.001), and frontal septal cells (p-value = 0.049). In the frontal septal cells, an increase of one year in age reduced the volume by 0.309, on average. According to Keros classification, the mean volumes were 10.07 and 25.64, respectively, for types II and III, both being greater than that of type I. Extracting volumetric data by using segmentation software in agger nasi cells, supra agger cells, and frontal septal cells may be useful for obtaining additional information related to age, in addition to possibly contributing to elucidating the anatomical variations in the region and an identification forensic tool.

In Vitro Quantitative Evaluation of Postprocessing Filter for Metal Artifact Reduction in Cone Beam Computed Tomography Images of Titanium and Zirconium Dioxide Implants.

Objective: To evaluate a postprocessing filter of a new imaging-processing software for analysis of metal artifact reduction. Methods: Eight artificial edentulous mandibles (phantoms), where titanium and zirconium dioxide implants had been installed in four different regions (i.e., incisors, canine, premolars, and molars). CBCT volume was acquired, and then, four types of filters were applied to the images: BAR filter and Multi-CDT NR filter (e-Vol DX) and Sharpening Filters 1x and 2x (OnDemand). Artifact was assessed by measuring the standard deviation (SD) of the gray values of filtered and unfiltered images. The comparison between implant material, teeth, and filters was performed by using ANOVA, whereas multiple comparisons were performed by using Bonferroni's test. The level of significance adopted was 5%. Results: The results showing higher SD values, which suggests a worse image, were obtained with titanium implants compared to zirconium dioxide ones. With regard to the four filters used, it can be seen that the lowest SD values were obtained with BAR and Multi-CDT NR filters and the highest with Sharpening Filters 1x and 2x, with no statistical difference between them, except regarding the molar region in titanium implants. Conclusion: The highest SD values were seen in zirconium dioxide implants, mainly in the region of anterior teeth. The BAR filter was found to be the most effective as its SD value decreased significantly, indicating that the image quality was improved.

Oral shedding of CMV and HSV-1 in hematopoietic stem cell transplantation patients.

OBJECTIVES: To evaluate the oral shedding of herpesviruses in patients undergoing hematopoietic stem cell transplantation (HSCT) and correlate it with oral mucositis (OM). METHODS: Saliva samples were collected before the HSCT and on day D + 8. Multiplex Polymerse Chain Reaction (PCR) was performed to detect herpes simplex virus (HSV)-1 and HSV-2, Epstein-Barr virus (EBV), Cytomegalovirus (CMV), Variella-zoster virus (VZV), and human herpesvirus (HHV)-6, HHV-7, and HHV-8. OM was assessed according to WHO criteria. RESULTS: Thirty one patients were enrolled, in which 20 of 31 (64.5%) were males; median age was 50 (21-70) years; 16 of 31 (51.6%) underwent allo-HSCT; and 15 of 31 (48.4%) underwent auto-HSCT. On D + 8, OM grades III and IV were observed in 8 of 31 (25.8%) patients. In the first salivary collection, EBV was found in 24 of 31 (77.4%), followed by HHV-6 (7/31, 22.6%) and HHV-7 (8/31 25.8%). In the second collection, EBV was found in 24 of 27(89%), followed by HSV-1 (8/27, 30%) and CMV, HHV-6, and HHV-7 (5/27, 18.5%, each one). On D + 8, OM grades II and IV were associated with the presence of HSV-1. HSV-1 was also associated with worsening degrees of OM on D + 15. CONCLUSION: The presence of HSV-1 and CMV in oral samples was more frequent on day D + 8 after HSCT. HSV-1 detection was associated with severity and worsening of OM. HSV-1 and CMV seem to be associated with oral dysbiosis due to HSCT.

Differentiation of periapical granuloma from radicular cyst using cone beam computed tomography images texture analysis.

OBJECTIVE: This study aimed to investigate the use of texture analysis for characterization of radicular cysts and periapical granulomas and to assess its efficacy to differentiate between both lesions with histological diagnosis. METHODS: Cone beam computed tomography (CBCT) images were obtained from 19 patients with 25 periapical lesions (14 radicular cysts and 11 periapical granulomas) confirmed by biopsy. Regions of interest were created in the lesions from which 11 texture parameters were calculated. Spearman's correlation analysis was performed and adjusted with Benjamini-Hochberg false discovery rate procedure (FDR <0.005). RESULTS: The texture parameters used to differentiate the lesions were assessed by using a receiver operating characteristic analysis. Five texture parameters were predictive of lesion differentiation for eight positions: angular second moment; sum of squares; sum of average; contrast; correlation. CONCLUSION: Texture analysis of CBCT scans distinguishes radicular cysts from periapical granulomas and can be a promising diagnostic tool for periapical lesions. CLINICAL SIGNIFICANCE: Texture analysis can be used in diagnostic and treatment monitoring to provide supplementary information.

Health-Related Quality of Life, Depressive Symptoms, and Kidney Transplant Access in Advanced CKD: Findings From the Chronic Renal Insufficiency Cohort (CRIC) Study.

RATIONALE & OBJECTIVE: Among individuals with chronic kidney disease (CKD), poor self-reported health is associated with adverse outcomes including hospitalization and death. We sought to examine the association between health-related quality-of-life (HRQoL) and depressive symptoms in advanced CKD and subsequent access to the kidney transplant waiting list. STUDY DESIGN: Prospective cohort study. SETTING & POPULATION: 1,676 Chronic Renal Insufficiency Cohort (CRIC) study participants with estimated glomerular filtration rates ≤ 30 mL/min/1.73 m2 at study entry or during follow-up. EXPOSURES: HRQoL ascertained by 5 scales of the Kidney Disease Quality of Life-36 Survey (Physical Component Summary [PCS], Mental Component Summary, Symptoms, Burdens, and Effects), with higher scores indicating better HRQoL, and depressive symptoms ascertained using the Beck Depression Inventory. OUTCOMES: Time to kidney transplant wait-listing and time to pre-emptive wait-listing. ANALYTIC APPROACH: Time-to-event analysis using Cox proportional hazards regression. RESULTS: During a median follow-up of 5.1 years, 652 (39%) participants were wait-listed, of whom 304 were preemptively wait-listed. Adjusted for demographics, comorbid conditions, estimated glomerular filtration rate slope, and cognitive function, participants with the highest scores on the Burden and Effects scales, respectively, had lower rates of wait-listing than those with the lowest scores on the Burden (wait-listing adjusted hazard ratio [aHR], 0.70; 95% CI, 0.57-0.85; P < 0.001) and Effects scales (wait-listing aHR, 0.74; 95% CI, 0.59-0.92; P = 0.007). Participants with fewer depressive symptoms (ie, Beck Depression Inventory score < 14) had lower wait-listing rates than those with more depressive symptoms (aHR, 0.81; 95% CI, 0.66-0.99; P = 0.04). Participants with lower Burden and Effects scale scores and those with higher Symptoms and PCS scores had higher pre-emptive wait-listing rates (aHR in highest tertile of PCS relative to lowest tertile, 1.58; 95% CI, 1.12-2.23; P = 0.01). LIMITATIONS: Unmeasured confounders. CONCLUSIONS: Self-reported health in late-stage CKD may influence the timing of kidney transplantation.

Association of volume and voxel intensity of the articular disc and lateral pterygoid muscle in migraine patients: a study with magnetic resonance imaging.

Objectives: To compare the volume and voxel intensity of articular disc and lateral pterygoid muscle (LPM) between a group of migraine patients and a control group (those without history of headache) by using magnetic resonance imaging (MRI).Patients and methods: MRI scans of 17 migraine patients and 15 healthy controls subjects were analysed and processed, using ITK-SNAP software, by a single investigator, for calculation of volumes and voxel intensity of articular disc and superior and inferior head of LPM.Results: There were statistically significant differences between migraine patients and controls regarding the volume and voxel intensity of articular disc and inferior head of LPM, increasing in migraine patients. Intra-rater was highly consistent and reproducible (intra-class correlation coefficient [ICC] = 1).Conclusions: Higher voxel intensity in disc and inferior head of LPM of MRI scans was linked to the increased volume of articular disc, inferior head of LPM and migraine.

Prevalence and Correlates of CKD in Hispanics/Latinos in the United States.

BACKGROUND AND OBJECTIVES: The prevalence of ESRD among Hispanics/Latinos is 2-fold higher than in non-Hispanic whites. However, little is known about the prevalence of earlier stages of CKD among Hispanics/Latinos. This study estimated the prevalence of CKD in US Hispanics/Latinos. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: This was a cross-sectional study of 15,161 US Hispanic/Latino adults of Cuban, Dominican, Mexican, Puerto Rican, Central American, and South American backgrounds enrolled in the multicenter, prospective, population-based Hispanic Community Health Study/Study of Latinos (HCHS/SOL). In addition, the prevalence of CKD in Hispanics/Latinos was compared with other racial/ethnic groups in the 2007-2010 National Health and Nutrition Examination Survey (NHANES). Prevalent CKD was defined as an eGFR <60 ml/min per 1.73 m(2) (estimated with the 2012 Chronic Kidney Disease Epidemiology Collaboration eGFR creatinine-cystatin C equation) or albuminuria based on sex-specific cut points determined at a single point in time. RESULTS: The overall prevalence of CKD among Hispanics/Latinos was 13.7%. Among women, the prevalence of CKD was 13.0%, and it was lowest in persons with South American background (7.4%) and highest (16.6%) in persons with Puerto Rican background. In men, the prevalence of CKD was 15.3%, and it was lowest (11.2%) in persons with South American background and highest in those who identified their Hispanic background as "other" (16.0%). The overall prevalence of CKD was similar in HCHS/SOL compared with non-Hispanic whites in NHANES. However, prevalence was higher in HCHS/SOL men and lower in HCHS/SOL women versus NHANES non-Hispanic whites. Low income, diabetes mellitus, hypertension, and cardiovascular disease were each significantly associated with higher risk of CKD. CONCLUSIONS: Among US Hispanic/Latino adults, there was significant variation in CKD prevalence among Hispanic/Latino background groups, and CKD was associated with established cardiovascular risk factors.

Photodynamic therapy for root canals infected with Enterococcus faecalis.

OBJECTIVE: The aim of this study was to investigate the effects of photodynamic therapy (PDT) on endodontic pathogens by evaluating the decrease in numbers of Enterococcus faecalis colonies in the canals of extracted human teeth. BACKGROUND DATA: Failure in endodontics is usually related to inadequate cleaning and disinfection of the root canal system. This is due to the establishment of microorganisms in areas where the instruments and chemical agents used during root canal preparation cannot eliminate them. PDT is a complementary therapeutic method that could be used to eliminate these remaining bacteria. PDT is a process in which radiation acts on a dye that is applied to the target organism, resulting in bacterial death. MATERIALS AND METHODS: Forty-six uniradicular teeth had their canals contaminated with bacteria and were incubated for 48 h at 35 degrees C. After that, the teeth were divided into a control group (CG) and a test group (TG). The 23 CG teeth did not undergo any intervention, whereas in the TG the teeth received a solution of 0.0125% toluidine blue for 5 min followed by irradiation using a 50-mW diode laser (Ga-Al-As) at a wavelength of 660 nm. Bacterial samples were taken before and after irradiation. In each of the samples, the number of colony-forming units (CFU) was counted. RESULTS: The mean decrease in CFU was 99.9% in the TG, whereas in the CG an increase of 2.6% was observed. CONCLUSION: PDT was effective as a bactericidal agent in Enterococcus faecalis-contaminated root canals.

In vivo study of the Nd:YAP laser in persistent periapical lesion.

OBJECTIVE: The aim of this study was to evaluate the therapeutic effect of ND:YAP laser in persistent lesions through signs and symptoms such as the presence of fistulas and pain, respectively. BACKGROUND DATA: Periapical lesions with bacterial invasion, giving origin to bacterial infections, appear many times during the endodontic treatment, which aims at preparing and disinfecting the root canal system, in canals with mortified pulp. The endodontic treatment aim at eliminating infections and reinfection prevention; however, sometimes re-treatment is necessary, and it can be complemented with paraendodontic surgery due to reinfection, which can also persist. METHODS: Our study group consisted of six clinical cases (endodontic treatment), with the introduction of a 300-microm optic fiber through the fistula channel, where three applications were carried out with an interval of 15 sec, each with a discharge of 300 mJ of energy and frequency of 30 Hz. RESULTS: After a 7-day interval, the signs and symptoms were absent, even after a follow-up of 18 months. It was also observed, through a microbiological study, the decrease of the local microbiota. CONCLUSIONS: Our results supported the use of Nd:YAP laser, in part since it created an unfavorable environment for the continuing development of microorganisms.
