title: Statute of the Elderly: analysis of the factors associated with awareness of the statute among the elderly Brazilian population

description: Abstract The scope of this article is to analyze the factors associated with awareness of the Statute of the Elderly by the non-institutionalized Brazilian population aged 60 years and older. It involves a cross-sectional and exploratory study, which used data from the Longitudinal Study of Health of Elderly Brazilians (ELSI-Brasil) conducted in 2015 and 2016. Statistical analysis was assessed by means of the chi-square test and with the use of binary logistic models. Awareness of the Statute of the Elderly was higher among the better educated elderly group (OR: 3.17; 95%CI: 2.19-4.60), those belonging to the highest quartile of the wealth index (OR: 2.96; 95%CI: 2.00-4.38), and among those who suffered discrimination based on age (OR: 1.73; 95%CI: 1.39-2.16). On the other hand, being 80 years old or older (OR: 0.59; 95%CI: 0.43-0.82) and having less communication with their children (OR: 0.56; 95%CI: 0.43-0.74) is associated with lesser awareness of this legislation. Many inequalities in awareness of the legislation, especially socioeconomic inequalities, were observed, revealing that awareness of established rights is not homogeneous. Awareness of the entire population regarding the prerogatives of the Statute of the Elderly is essential for advances in its applicability and effectiveness.

title: Epidemiological-clinical profile and mortality in patients coinfected with Trypanosoma cruzi/HIV: experience from a Brazilian reference center

description: ABSTRACT Background: The recent urbanization of Chagas disease (CD) has contributed to a greater risk of coexistence with human immunodeficiency virus (HIV) and AIDS. Methods: This retrospective observational study included patients who were followed at INI-Fiocruz between July 1986 and October 2021. All patients underwent an assessment protocol that included sociodemographic profile, epidemiological history, and clinical evaluation. Descriptive data analyses included reports of the medians and frequencies of variables of interest. Differences in medians between groups were tested using the Mann-Whitney U test. Differences in frequency were tested using Fisher's exact test. Results: Among 2201 patients, 11 (0.5%) were identified with Trypanosoma cruzi/HIV coinfection. Of these, 63.6% were women with a median age of 51.0 years old. Two patients had the indeterminate form of CD, six had the cardiac form, two had the digestive form and one had the cardio-digestive form. Half of the patients were undergoing antiretroviral treatment at the time of coinfection diagnosis with a median CD4+ count of 350 cells/μL and a viral load of 1500 copies/μL. Four patients underwent a xenodiagnosis test at coinfection diagnosis, which all yielded positive results; two of them presented high parasitemia under the risk of reactivation. Prophylaxis for CD reactivation was administered to four patients; two with ketoconazole and two with benznidazole. Six patients died after a median follow-up of 22.5 months, with AIDS being the most common cause of death. Only one case of reactivation was observed. Conclusions: Early diagnosis and prompt treatment of CD reactivation dramatically reduced mortality. Identification of Trypanosoma cruzi/HIV co-infection is crucial to planning a close follow-up of coinfected patients.

title: Higher frequency of specific periodontopathogens in hypertensive patients. A pilot study

description: Abstract Periodontitis and arterial hypertension are two of the pathologies with the highest global prevalence; evidence reported so far has been favorable to an association between them. This cross-sectional study aimed to evaluate and compare the microbiological counts of hypertensive and normotensive patients with periodontitis. Sociodemographic, behavioral, systemic health data and periodontal clinical parameters were assessed. Counts of A. actinomycetemcomitans, P. intermedia, P. gingivalis and F. nucleatum were performed by real-time polymerase chain reaction using subgingival biofilm samples. Thirty-eight patients were included in this preliminary analysis, divided into two groups: Normotensive Group (NG) (n = 14) and Hypertensive Group (HG) (n = 24). Patients diagnosed with periodontitis composed both groups. Data analysis was performed with significance level of 5%. There was no significant difference between groups for clinical periodontitis diagnosis. In addition, hypertensive individuals had higher P. intermedia, P. gingivalis, and F. nucleatum counts when compared to normotensive individuals. The parameters probing pocket depth, bleeding on probing, and A. actinomycetemcomitans count did not presented statistical differences between groups. With these preliminary results, it can be concluded that the presence of arterial hypertension may be associated with a greater quantity of periodontopathogenic bacterial of some species in individuals with periodontitis.

title: A systematic review of the effect of the school-based drug prevention program Keepin’ it REAL: translated and implemented in Brazil by PROERD

description: Abstract The Drug Resistance Educational Program (PROERD) is Brazil’s most widespread school-based prevention program; its current curriculum is based on the North American Keepin’ it REAL (kiR) program. There is no evidence of the effectiveness of PROERD in preventing drug use, pointing to the need for further studies to understand these findings. The aim of the study was to synthesis the evidence of the effect of the kiR curriculum (PROERD) through a systematic review. We found 17 studies that reported the effects of different versions of kiR on drug use and/or violence. Except for the Brazilian study, no studies were found that assessed the effect on drug use of the version applied by police officers (DARE-kiR), the same one implemented by PROERD. Favorable evidence of kiR in drug use prevention was found for the 7th-grade curriculum, which contradicts the PROERD’s null-effect results. No international evidence of the effect of kiR was found in the 5th-grade curriculum, in the same line as the PROERD’s study. It is suggested that PROERD’s 7th-grade curriculum should be revised to reflect international results and that the 5th-grade curriculum should be reconsidered in light of the negative international evidence.

title: Oral mucoceles: A Brazillian Multicenter Study of 1,901 Cases

description: Abstract Oral mucocele (OM) is the most common lesion of minor salivary glands. The present study aimed to report the clinical and demographic features of a large series of OMs and identify possible predictive variables associated with the recurrence rate of these lesions. A retrospective descriptive cross-sectional study was performed. A total of 43,754 biopsy records from four pathology services in Brazil were analyzed. All cases of OMs were reviewed, and clinical and demographic data were collected. The study comprised 1,002 females (56.2%) and 782 males (43.8%), with a mean age of 19.8±16.4 years (range: 01-87 years) and a 1.3:1 female-to-male ratio. The lower lip (n=1,160; 67.4%), and floor of the mouth (n=172; 10.0%), were the most common affected sites, presenting clinically as nodules (n=978; 79.4%) of smooth surface (n=428; 77.5%) and normal color (n=768, 46.7%). Excisional biopsy was the treatment in most cases (n=1,392; 78.0%). Recurrent OMs represented 6.2% of all diagnosed cases (n=117). OMs recurred more commonly in younger patients (aged&lt;20 years) (p&lt;0.0001), in lesions larger than 2 cm in diameter (p&lt;0.0001), and in those located in the ventral tongue (p=0.0351). Also, recurrence rates were higher significantly in cases treated with laser surgery than in those with conventional surgery (p=0.0005). Patients with OMs should be carefully informed of its possible recurrence, especially when found on the ventral tongue of young patients.

title: Effect of phytic acid on bond strength and interfacial integrity of universal adhesive to deep dentin

description: Abstract This study investigated the effect of phytic acid (IP6) in different concentrations and application times on microtensile bond strength (µTBS) and interfacial integrity of universal adhesive to deep dentin. Flat deep dentin surfaces of 48 human molars were either etched with 37% phosphoric acid (PA) for 15 sec (control); or received no acid treatment and universal adhesive was applied directly in a self-etch mode (SE); or divided according to IP6 concentration (C) into two main groups: C1, 0.5%, and C2, 1%. Specimens of IP6 groups were further subdivided into three subgroups according to application time of IP6 (T) where; T1, 15 sec; T2, 30 sec and T3, 60 sec. Single Bond Universal Adhesive was then applied and resin composite blocks were built-up. Forty Specimens were then sectioned to produce resin/dentin beams that were used for µTBS testing using a universal testing machine. The remaining eight specimens were sectioned into slabs that were immersed into ammonical silver nitrate solution and nanoleakage was observed using a field emission scanning electron microscope (FE-SEM). The results showed that the application of IP6 in 0.5% and 1% produced significantly higher µTBS and less nanoleakage compared to PA and SE groups. Also, the application of IP6 for 60 sec recorded the highest µTBS and the lowest nanoleakage followed by 30 sec, and 15 sec respectively. Therefore, conditioning of deep dentin with IP6 enhances µTBS and interfacial integrity of universal adhesive to deep dentin in comparison to PA etching or using the universal adhesive in SE mode.

title: Distribution of adult semiology in medical schools in Brazil

description: Abstract: Introduction: Semiology is the basis of clinical practice and its teaching is essential in the medical course. This study was developed to fill a gap in the knowledge about its distribution in Brazil. Objective: To analyze the distribution of adult semiology in Brazilian medical schools. Method: Cross-sectional descriptive study with 226 Brazilian medical schools that provided the distribution of semiology on the Internet among the 335 active schools in December 2020 (67.5%) The variables studied were school geographic region, administration and free tuition, time of existence of the course, course load of the regular course, clerkship and semiology, and year(s) or semester(s) in which semiology was offered in the curriculum. Data analysis was descriptive and the associations were analyzed using: Student’s t, Chi-square, Analysis of Variance, Mann-Whitney-U, Kruskal Wallis and Wilcoxon tests. The significance level was set at p &lt; 0.05. Result: Semiology was more frequently offered only in the 4th semester (n = 40), followed by its offer in two semesters, the 4th and 5th and 3rd and 4th. Among the 226 schools, 142 integrated semiology into modules or axes (62.8%). Among the 117 schools that provided the semiology course load, its median was 240.0 hours (P25-75 = 165.4 - 338.2), with no statistical difference by geographic region, type of administration and time of existence of the course. The median of the theoretical course load [77.5 hours (P25-75 = 51.7 - 123.5)] was lower than the practical course load [147.0 hours (P25-75 = 64.5 - 180.0)], Z = - 3,99, p &lt; 0,01. The median of the percentage of semiology course load during the course was 2.9% (P25-75 = 2.0 - 4.0). Conclusion: Semiology is more frequently offered in the 4th semester and its median course load is similar in Brazilian geographic regions and by school administration type and time of existence of the assessed schools.

title: Preparation of angiotensin I-converting enzyme (ACE) inhibitory peptides from Tie Guanyin tea residue protein using two-step enzymatic hydrolysis

description: Abstract In this study, we attempted to prepare novel angiotensin I-converting enzyme inhibitory (ACEI) peptides from Tie Guanyin tea residue protein (TTRP). Different proteases were used to hydrolyze TTRP to prepare ACEI peptides, neutral protease and alkaline protease hydrolysates exhibited higher ACEI activity and was chosen in further hydrolysis treatment. Response surface methodology (RSM) was used to optimize the enzymatic condition, and the results indicated that the optimal conditions of enzymatic hydrolysis were: 4% (w/v) of TTRP in water was hydrolyzed with 3500 U/g neutral protease at 50 °C and pH 6.5 for 2.5 h in the first step and then with 5000 U/g alkaline protease at 50 °C and pH 10.0 for 3 h in the second step. Under the optimum condition, the ACE inhibitory rate of the final products was 88.45% ± 0.45% at the concentration of 1.0 mg/mL. Moreover, ACEI peptides derived from TTRP showed good stability under different temperatures, pHs, metal ions and gastrointestinal digestion. These results indicated that the TTRP has potential to be used for preparing ACEI peptides.
