Inflammatory response to bioceramic and epoxy resin-based endodontic sealers implanted in mice subcutaneous tissue: An in vivo study.

To evaluate the inflammatory tissue response to BioRoot™ RCS (BR) and AH Plus Jet (AHPJ) sealers implanted in mice subcutaneous tissue. It was hypothesized that the inflammatory tissue response to BR would be milder than to AHPJ. An in vivo study was carried out using isogenic mice. The sealers were implanted during standardized surgical procedures. The inflammatory response was evaluated by microscopic analysis and von Kossa reaction in the reactionary tissue around the specimens after 7, 21, and 63 days. For comparisons, a zinc oxide and eugenol sealer (ZOE) was used as a positive control, in addition to a negative control without a sealer (n = 10 per group/period). All statistical analyses considered a significance level of 5%. All endodontic sealers triggered an inflammatory tissue response after 7 days. BR had a higher inflammatory cell count and a thicker fibrous capsule when compared with AHPJ, but both were less inflammatory than ZOE (p < .001). After 21 days, BR continued to trigger an intense inflammatory tissue response, higher in both microscopic parameters compared to AHPJ, and a thicker fibrous capsule than ZOE (p < .001). After 63 days, the inflammatory tissue response decreased in BR, matching the fibrous capsule thickness with AHPJ and ZOE. BR promoted intense calcium precipitation in all study periods. After 63 days, AHPJ and BR sealers were more biocompatible to subcutaneous mice tissue, but AHPJ present better early inflammatory response, as well as BR showed potential bioactivity. RESEARCH HIGHLIGHTS: The inflammatory tissue response triggered by a bioceramic endodontic sealer (BR) was not milder than that triggered by an epoxy-resin based endodontic sealer (AHPJ) during the first 3 weeks, considering the microscopic analysis of the reactionary tissue.

Outpatient and inpatient dental care for patients with disabilities in Brazil's public healthcare system: A population-based approach from 2014 to 2023.

AIM: The aim of this study was to evaluate outpatient and inpatient dental care for patients with disabilities from 2014 to 2023. MATERIAL AND METHODS: A time series analysis was carried out with data from Brazil's public healthcare system, considering the outpatient productivity of Special Needs Dentistry specialists and hospitalizations (inpatient admissions) of patients with disabilities for dental procedures, both normalized to every 100,000 inhabitants (incidence). The significance level was set at 5%. RESULTS: In the last 10 years, 22,420,859 procedures were carried out and 89,380 hospitalizations were approved. Trend analysis showed no significant temporal variation in the incidence of both variables. Regarding the procedures, the majority were low-complexity (82.1%, p < .001) and clinical (71.2%, p < .001). Periodontal (19.9%) and restorative (19.5%) procedures were the most frequent. Considering the hospitalizations, almost (R$) 40 million was allocated, and the majority were classified as elective (71.9%, p = .002) and of short duration (less than a day). CONCLUSION: Dental care for patients with disabilities presented patterns related to the types of procedures, complexity and circumstance, in addition to not showing significant temporal variation over the last 10 years.

The historical ecological background of West Nile virus in Portugal indicates One Health opportunities.

West Nile (WNV) is a zoonotic arbovirus with an expanding geographical range and epidemic activity in Europe. Not having yet experienced a human-associated epidemic, Portugal remains an outlier in the Mediterranean basin. In this study, we apply ecological niche modelling informed by WNV historical evidence and a multitude of environmental variables from across Portugal. We identify that ecological backgrounds compatible with WNV historical circulation are mostly restricted to the south, characterized by a warmer and drier climate, high avian diversity, specific avian species and land types. We estimate WNV ecological suitability across the country, identifying overlaps with the distributions of the three relevant hosts (humans, birds, equines) for public and animal health. From this, we propose a category-based spatial framework providing first of a kind valuable insights for WNV surveillance in Portugal under the One Health nexus. We forecast that near future climate trends alone will contribute to pushing adequate WNV ecological suitability northwards, towards regions with higher human density. This unique perspective on the past, present and future ecology of WNV addresses existing national knowledge gaps, enhances our understanding of the evolving emergence of WNV, and offers opportunities to prepare and respond to the first human-associated epidemic in Portugal.

Subjective and Objective Monitoring Markers: Are They Related to Game Performance Indicators in Elite Female Volleyball Players?

PURPOSE: This cohort study aimed to investigate the relationship between subjective (wellness and internal training load [ITL]) and objective (neuromuscular fatigue) monitoring markers and performance aspects (reception quality [RQ] and attack efficiency [AE]) in professional female volleyball players. METHODS: The study was conducted over an 8-week period during the final mesocycle of the competitive phase. A total of 24 training sessions and 10 matches were included in the analysis. Subjective measures of wellness and ITL were assessed, and neuromuscular fatigue was evaluated using countermovement-jump (CMJ) height. RQ and AE were determined based on game statistics. RESULTS: The study found a positive relationship between wellness and RQ, particularly affecting outside hitters and liberos. ITL showed a positive association with AE, primarily impacting outside hitters, opposite hitters, and middle blockers. Additionally, ITL demonstrated a negative correlation with RQ, mainly affecting outside hitters and liberos. CMJ performance was associated with AE, where a decrease in CMJ height was linked to reduced AE. CONCLUSIONS: The findings highlight the importance of considering players' wellness scores in training and match strategies for different positions. Careful management of training loads, considering both physical and technical demands, is crucial for optimizing performance outcomes. Monitoring neuromuscular fatigue, as indicated by CMJ performance, is particularly relevant for outside hitters, opposite hitters, and middle blockers involved in attack actions. Coaches, trainers, and sports practitioners can use these insights to develop position-specific training protocols and implement effective strategies for maintaining or improving performance metrics under various stressors.

Territorial Disparities in Dental Care for Disabled Persons and Oral Health-Related Indicators: A Population-Level Approach in Brazil's Public Healthcare System from 2014 to 2023.

This study evaluated territorial disparities in dental care for disabled persons in Brazil's public healthcare system from 2014 to 2023. The person-year incidence of outpatient dental procedures carried out by special care dentistry specialists and hospitalizations for dental procedures for disabled persons were compared across different regions and against the national estimate. In addition, productivity was correlated with oral health-related indicators. The significance level was set at 5%. The northern region exhibited the highest outpatient productivity, while the southern region showed lower productivity compared to the national estimate (both p-value < 0.05). This pattern was reversed in inpatient productivity (both p-value < 0.05), with the northeastern and central-western regions also below average (both p-value < 0.05). There were no significant correlations between the indicators and inpatient productivity, but outpatient productivity was positively correlated with the proportions of inhabitants who self-rated their general and oral health as "poor" or "very poor", who have never visited a dentist, and who visited a dentist for tooth extraction (all p-values < 0.05). Territorial disparities in dental care for disabled persons were observed within Brazil's public healthcare system, and they were correlated with unfavorable oral health-related indicators at the population level.

The effects of NLRP3 inflammasome inhibition or knockout in experimental apical periodontitis induced in mice.

OBJECTIVE: To evaluate the effects of NLRP3 inflammasome inhibition or knockout in experimental apical periodontitis (AP) induced in mice. METHODS: The experimental AP was induced by pulpal exposure. To evaluate NLRP3-specific inhibitor medication (MCC950), WT mice received intraperitoneal injections, while the control received PBS (n = 10). In addition, to evaluate NLRP3 knockout, 35 wild-type (WT) and 35 NLRP3-/- mice were divided into a control group (without pulpal exposure, n = 5) and three experimental groups: after 2, 14 and 42 days after pulpal exposure (n = 10). Microscopic and molecular analyzes were carried out using a significance level of 5%. RESULTS: Exposure to MCC950 did not affect the periapical lesion size after 14 days (P = 0.584). However, exposed mice had a lower expression of IL-1ß, IL-18 and caspase-1 (P = 0.010, 0.016 and 0.002, respectively). Moreover, NLRP3-/- mice showed a smaller periapical lesion after 14 and 42 days (P = 0.023 and 0.031, respectively), as well as a lower expression of IL-1ß after 42 days (P < 0.001), of IL-18 and caspase-1 after 14 (P < 0.001 and 0.035, respectively) and 42 days (P = 0.002 and 0.002, respectively). NLRP3-/- mice also showed a lower mRNA for Il-1ß, Il-18 and Casp1 after 2 (P = 0.002, 0.036 and 0.001, respectively) and 14 days (P = 0.002, 0.002 and 0.001, respectively). CONCLUSIONS: NLRP3 inflammasome inhibition or knockout can attenuate the inflammatory events that result in the periapical lesion (AP) formation after pulpal exposure in mice. CLINICAL RELEVANCE: The NLRP3 inflammasome may be a therapeutic target for AP, and new approaches may verify the impact of its inhibition (through intracanal medications or filling materials) on the bone repair process and treatment success.

Family Vulnerability Scale: validity evidence in primary health care.

OBJECTIVE: Investigate evidence of validity of the Family Vulnerability Scale (EVFAM-BR) as an instrument to support population-based management in primary health care (PHC), in the scope of Health Care Planning (PAS). METHODS: This is a psychometric study to assess any additional evidence of the internal structure of EVFAM-BR using confirmatory factor analysis (CFA) and network analysis (NA). A preliminary version of the scale with 38 items was submitted to patients of PHC facilities that use the PAS methodology, distributed across the five regions of Brazil. For the primary CFA data, factor loadings and predictive power (R2) of the item were used. Seven model adjustment indices were adopted and reliability was measured by three indicators, using Bayesian estimation. RESULTS: The preliminary version of the scale was applied to 1,255 patients. Using the AFC, factor loadings ranged from 0.66 to 0.90 and R2 from 0.44 to 0.81. Both the primary indicators and the model adequacy indices presented satisfactory and consistent levels. According to the NA, the items were appropriately associated with their peers, respecting the established dimensions, thus demonstrating sustainability and stability of the proposed model. CONCLUSIONS: The evidence of validity presented by EVFAM-BR indicates, for the first time in Brazil, a concise instrument that is able to assertively measure family vulnerability, potentially supporting population-based management.

Sarcopenic obesity defined by the ESPEN and EASO consensus statement in older women: Risk of falls and bone mineral density implications.

PURPOSE: To apply the ESPEN-EASO diagnostic criteria for Sarcopenic Obesity (SO) in older women and to assess its association with the risk of falls, fear of falls (FOF), and bone mineral density (BMD). METHODS: After exclusion criteria, 232 women aged ≥60 years (68.2 ± 6.1) were enrolled in the study. Volunteers had handgrip strength (HGS; dynamometer) and body composition assessed by DXA before risk of falls was evaluated using the QuickScreen and FOF evaluated by the Falls Efficiency Scale. SO was defined according to the ESPEN-EASO algorithm, which includes reduced HGS and fat-free mass, and elevated fat mass. RESULTS: The prevalence of SO was 6.5 %, which was associated with a higher proportion of fallers in the previous year (X2 6.2, P = 0.04), reduced reaction time (X2 6.2, P = 0.04), reduced sit-to-stand performance (X2 6.2, P = 0.04), and a higher probability of falls [ꭓ2(6) = 17.689, p = 0.004]. FOF was lower in the eutrophic group (ꭓ2(2) = 15,662, p < 0,001) than both the obesity (p = 0.001) and SO (p = 0.05) groups. For total and femoral neck BMD, the eutrophic group presented significantly lower values (1.05 and 0.79 g/cm2) than the obesity group (1.10 and 0.87 g/cm2), but similar to the SO group (1.02 and 0.83 g/cm2). These results remained significant after adjustments for potential confounders. CONCLUSIONS: SO specified by the ESPEN-EASO framework was associated with a higher risk of falls but not with increased FOF than obesity alone. The favorable influence of overweight and obesity on BMD seems to be attenuated in individuals with SO. Our findings support the clinical significance of the ESPEN-EASO definition.

Root canal conicity determination of primary second molars using nanotomography: An in vitro study.

BACKGROUND: The conicity of the root canals of primary teeth is an important measure for endodontic therapies. However, determining this conicity depends on the methods employed, which requires further investigation. AIM: The aim of this study was to determine the conicity of the root canals of the upper and lower primary second molars using nanotomography (nCT). DESIGN: An in vitro study was performed using nine primary second molars, both upper and lower, subjected to nCT. Comparisons between the diameters of root canals were performed between the thirds (cervical-D0, middle-D5, and apical-D7). The conicity (%) was determined for each root canal from cervical to apical. Data were statistically analyzed with a significance level of 5%. RESULTS: The conicity ranged from 2% to 8% for the upper primary second molars. Significant differences in root canal diameter between the thirds (D0, D5, and D7 points) were observed in the mesio- and distobuccal roots (p < .05), but not in the palatal roots (p > .05). For the lower primary second molars, the conicity ranged from 2% to 17%, as well as significant differences in root canal diameter between the thirds (D0, D5, and D7 points) were observed in all roots (distal, mesiobuccal, and mesiolingual; p < .05). CONCLUSION: The conicity of the upper primary second molars was different from that of the lower ones, which showed a greater variability.

Atypical evolution of collapsing FSGS in extreme elderly: case report / Evolução atípica de GESF Colapsante na velhice extrema: relato de caso

Introduction: Segmental and Focal Glomerulosclerosis (FSGS) is an entity characterized by glomerular damage involving the podocyte as the main target. A variant with a worse prognosis, poor response to corticosteroid therapy, and rapid progression to end-stage renal disease is recognized as collapsing FSGS. Case Report: A 102-year-old man with nephrotic syndrome and acute kidney injury underwent renal biopsy, revealing collapsing FSGS. He achieved an excellent response to immunosuppressive treatment, presenting renal recovery, and was discharged from dialysis treatment. Discussion: Diagnosis and definition of treatment in the elderly are challenging, and each case must be individualized and have functionality and risk assessed in a naturally immunosuppressed population.

Relato de Caso: Um homem de 102 anos com síndrome nefrótica e lesão renal aguda foi submetido a biópsia renal, revelando GESF colapsante. Ele obteve excelente resposta ao tratamento imunossupressor, apresentando recuperação renal e recebendo alta de terapia renal substitutiva. Discussão: Diagnóstico e definição de tratamento nos idosos são desafiadores, devendo-se individualizar cada caso, avaliar funcionalidade e risco em uma população naturalmente imunossupressa.

Intoxicações exógenas por raticidas notificadas no Brasil entre 2008 e 2022 / Exogenous poisoning by rodenticides reported in Brazil between 2008 and 2022

Objetivo: avaliar as notificações de intoxicação exógena por raticida no Brasil entre 2008 e 2022. Métodos: foi realizado um estudo ecológico, do tipo série temporal, avaliando a quantidade anual de notificações nos últimos 15 anos, considerando os casos confirmados pelo Sistema de Informação de Agravos de Notificação (SINAN). A tendência temporal e as razões de incidência antes e durante a pandemia de COVID-19 foram examinadas com nível de significância de 5%. Resultados: entre 2008 e 2022, 48.448 notificações de intoxicação exógena por raticidas foram registradas. A tendência temporal foi estabelecida como estacionária nos últimos 15 anos (p = 0,285), mas tornou-se, significativamente, crescente ao remover os anos relacionados à pandemia de COVID-19 (p = 0,001; VPA = 5,4% [IC95% = 2,1, 8,6). Além disso, ao comparar com período pré-pandemia, a incidência de notificações foi 34% menor (RI = 0,66 [IC95% = 0,59, 0,73]) no primeiro e 28% menor (RI = 0,72 [IC95% = 0,65, 0,79]) no segundo ano da pandemia de COVID-19. Por fim, observou-se que 82,2% das circunstâncias foram tentativas de suicídio, 89,4% foram exposições do tipo aguda-única e a maioria (91,1%) evoluíram para cura sem sequelas. Conclusão: foi possível concluir que as intoxicações exógenas por raticidas persistem como um problema de Saúde Pública no Brasil.

Objectives: to evaluate notifications of exogenous poisoning by rodenticides in Brazil between 2008 and 2022. Methods: an ecological time-series study was carried out, evaluating the annual number of notifications in the last 15 years, considering the cases confirmed by the Notifiable Diseases Information System (SINAN). Temporal tendency and incidence ratios before and during the COVID-19 pandemic were examined at a 5% significance level. Results: between 2008 and 2022, 48,448 notifications of exogenous poisoning by rodenticides were reported. The temporal tendency was established as stationary over the last 15 years (p = 0.285) but became significantly increasing when removing the COVID-19 pandemic years (p = 0.001; VPA = 5.4% [95%CI = 2 .1, 8.6). In addition, when compared to the pre-pandemic period, the incidence of notifications was 34% lower (IRR = 0.66 [CI95% = 0.59, 0.73]) in the first and 28% lower (IRR = 0,72 [CI95% = 0.65, 0.79]) in the second year of the COVID-19 pandemic. At last, it was observed that 82.2% of the circumstances were suicide attempts, 89.4% were acute-single exposures, and most (91.1%) evolved to cure without sequelae. Conclusion: it was possible to conclude that exogenous poisoning by rodenticides persists as a Public Health problem in Brazil.

Is There a Relationship Between Birth Quartile and Vertical Jump Performance Among Young Male Elite Volleyball Athletes?

Vertical jump is an important skill that influences volleyball performance. In this study, we analyzed the relationship between vertical jump performance and birth quartile of Brazilian male youth volleyball players. We calculated chi-square goodness-of-fit tests to compare the athletes' birthdate distributions in quarters of their birth years (Q1, Q2, Q3, and Q4) according to player age categories (U17, U18, U19, and U21). We calculated one-way ANOVAs to compare spike jump and block jump heights of players born in different quarters of the same year. Overall, we found a relative age effect (i.e., more players with birth dates early in the birth year) in U17 (p < .001), U18 (p < .001), U19 (p < .001), and U21 (p = .04). Regarding vertical jump performance, U18 athletes born in Q2 reached higher spike jump heights (p = .006) and block jump heights (p = .002) than athletes born in Q4, and U19 athletes born in Q1 reached higher block jump heights than athletes born in Q3 (p = .049). There were no significant differences in vertical jump performance across birth quartiles among U17 and U21 athletes. Thus, a relative age effect was present in all age categories but not always reflected in vertical jump performance. Volleyball coaches and policymakers are still advised to employ strategies to ensure fairer opportunities for players born later in the year of their eligibility dates, as we found RAE to be sometimes, but not always, related to higher spike or block jump heights even among these older adolescents and young adult athletes.

Prevalence of sarcopenia in patients with chronic kidney disease: a global systematic review and meta-analysis.

Sarcopenia is a risk factor for adverse clinical outcomes in chronic kidney disease (CKD) patients, including mortality. Diagnosis depends on adopted consensus definition and cutoff values; thus, prevalence rates are generally heterogeneous. We conducted a systematic review and meta-analysis to investigate the global prevalence of sarcopenia and its traits across the wide spectrum of CKD. A systematic search was conducted using databases, including MEDLINE and EMBASE, for observational studies reporting the prevalence of sarcopenia. We considered sarcopenia according to the consensus definition of the European Working Group on Sarcopenia in Older People (EWGSOP), the Asian Working Group for Sarcopenia, the Foundation for the National Institutes of Health Sarcopenia Project, and the International Working Group on Sarcopenia (IWGS). Subgroup analyses by CKD stages, consensus, and gender were performed. Pooled prevalence was obtained from random-effect models. A total of 140 studies (42 041 patients) across 25 countries were included in this systematic review and meta-analyses. Global prevalence of sarcopenia was 24.5% [95% confidence interval (CI): 20.9-28.3) and did not differ among stages (P = 0.33). Prevalence varied according to the consensus definition from 11% to 30%, with no significant difference (P = 0.42). Prevalence of severe sarcopenia was 21.0% (95% CI: 11.7-32.0), with higher rates for patients on dialysis (26.2%, 95% CI: 16.6-37.1) compared to non-dialysis (3.0%, 95% CI: 0-11.1; P < 0.01). Sarcopenic obesity was observed in 10.8% (95% CI: 3.5-21.2). Regarding sarcopenia traits, low muscle strength was found in 43.4% (95%CI: 35.0-51.9), low muscle mass in 29.1% (95% CI: 23.9-34.5), and low physical performance in 38.6 (95% CI: 30.9-46.6) for overall CKD. Prevalence was only higher in patients on dialysis (50.0%, 95% CI: 41.7-57.4) compared to non-dialysis (19.6%, 95% CI: 12.8-27.3; P < 0.01) for low muscle strength. We found a high global prevalence of sarcopenia in the wide spectrum of CKD. Low muscle strength, the primary sarcopenia trait, was found in almost half of the overall population with CKD. Patients on dialysis were more prevalent to low muscle strength and severe sarcopenia. Nephrology professionals should be aware of regularly assessing sarcopenia and its traits in patients with CKD, especially those on dialysis.

Wound Healing Effect of Lippia sidoides and Myracrodruon urundeuva Nanogel.

Wound healing is a natural regenerative response to tissue injury and the conventional treatments consists of the use wound dressings with local administration of medicines, but, in some cases, are only partially effective and limited by toxicity or ineffective anti-microbial protection. Medicinal plants such as Lippia sidoides and Myracrodruon urundeuva have shown interesting pharmacological activities, allied to this, the association of these medicinal plants and nanotechnology, could mean an advantage in relation to classical approach. This study investigated the effect of a nanogel loaded with Lippia sidoides essential oil and Myracrodruon urundeuva extract (NAA) in an excisional wound healing model in rats. Animals were anesthetized and skin wounds were made using a metal punch. The groups were treated with vehicle, NAA or collagenase gel, for 7, 14 or 21 days and then sacrificed for tissue analysis. NAA did not show acute dermal irritation, further significantly reduced (p<0.05) the final wound area, accelerated the wound contraction and organization of collagen in the group treated for 14 days. The data presented here demonstrate the therapeutic potential for the use of nanotechnology associated with medicinal plants and provides evidence that corroborate with the use of L. sidoides and M. urundeuva as healing medicinal plants.

Pioneer of Cardiothoracic Surgery - Luiz Tavares da Silva

ABSTRACT Luis Tavares revolutionized cardiac surgery, always bringing the most modern instruments and equipment from his travels to England - surgical forceps, scissors, scalpels, etc. He always insisted that he was not just a thoracic surgeon, for his work extended over a wide field and created three important cardiac surgery centers which promoted a great development of cardiology. He carried out the first open heart surgery (atrial septal defect) employing extracorporeal circulation and closure of a ventricular septal defect with deep surface hypothermia of north and northeast Brazil. He promoted an intense scientific exchange program between Recife and England, resulting in significant advances in medicine, and participated directly in the creation of HEMOPE), leading to radical changes and improvements in blood therapy in the whole country. The PROCAPE, inaugurated in 2006, was the result of the cardiac center created by him in early 1970 at Hospital Oswaldo Cruz and can be considered the second largest public-university cardiology center in Brazil. He is thus widely regarded as an outstanding name in medicine in the 20th century and one of the fathers of modern cardiac surgery in Brazil.

Activation of gelatinases in permanent human teeth after different experimental radiotherapy protocols.

The objective of this study was to compare the activation of gelatinases in dentin-enamel junction (DEJ) and underlying dentin of permanent teeth after experimental radiotherapy in conventional and hypofractionated modalities. Newly extracted third molars (n = 15) were divided into three experimental radiotherapy groups: control, conventional (CR), and hypofractionated (HR) (n = 5 per group). After in vitro exposure to ionizing radiation, following standardized protocols for each modality, a gelatinous substrate was incubated on the tooth slices (n = 10 per group). Activation of gelatinases was measured by in situ zymography, expressed in arbitrary fluorescence units (mm2) from three tooth regions: cervical, cuspal, and pit. Fluorescence intensity was compared among radiotherapy protocols and tooth regions in each protocol, considering a significance level of 5%. Considering all tooth regions, the fluorescence intensity of the CR group was higher than the HR and control groups, both in DEJ and underlying dentin (p <0.001). In addition, the fluorescence intensity was higher in underlying dentin when compared to DEJ in all groups (p <0.001). Considering each tooth region, a statistically significant difference between CR and HR was only observed in the pit region of underlying dentin (p <0.001). Significant and positive correlations between fluorescence intensities in DEJ and underlying dentin were also observed (p <0.001). Experimental radiotherapy influenced the activation of gelatinases, as well as exposure to the conventional protocol can trigger a higher activation of gelatinases when compared to hypofractionated, both in DEJ and underlying dentin.

Caries-related hospital morbidity in the Brazilian Unified Health System from 2008 to 2022.

Dental caries is an important Public Health issue. However, the treatment of this disease in tertiary dental care requires further investigation. Therefore, the objective of this study was to evaluate caries-related hospital morbidity in the Brazilian Unified Health System (SUS) from 2008 to 2022. An ecological study was conducted with secondary data on caries-related Hospital Admission Authorizations (AIH) and in-hospital dental procedures (IDP). Data were collected nationwide and statistical analysis was performed with a significance level (p) of 5%. In the last 15 years, 3,474 caries-related AIH and 63,657 IDP were approved within SUS. There was a significant upward trend in the number of caries-related AIH (p = 0.018) and a stationary trend in the number of caries-related IDP (p = 0.841). Moreover, from 2008 to 2022, R$ 1,160,843.09 was allocated for caries-related AIH. Hospital mortality was 0.29% (10 deaths), and 75.1% were elective inpatient admissions. Among SUS users, adults constituted the majority (49%), with a higher frequency of males (59.8%) and whites (46.2%). The most frequent type of caries-related IDP was restoration of permanent teeth (55.3%). Nonetheless, during the COVID-19 pandemic years, significant reductions in caries-related AIH and IDP within the SUS were observed (all p <0.05). Thus, within the SUS, caries-related tertiary dental care has shown a specific pattern over the last 15 years, including an increase in hospitalizations and a high number of in-hospital dental procedures, especially before the COVID-19 pandemic onset.

Baciloscopia para hanseníase no Sistema Único de Saúde do Brasil entre 2013 e 2022 / Bacilloscopy for leprosy in Brazil's public health system between 2013 and 2022

Objetivo: Avaliar a quantidade anual de baciloscopias para hanseníase realizadas no Sistema Único de Saúde (SUS) nos últimos dez anos. Métodos: Foi realizado um estudo ecológico, longitudinal, retrospectivo e quantitativo, utilizando dados do Sistema de InformaçõesAmbulatoriais (SIA/SUS). A quantidade de baciloscopias para hanseníase a cada 100.000 residentes foi estimada para o Brasil e suas cinco macrorregiões, avaliada entre 2013 e 2022 com nível de significância (a) de 5%. Resultados:Mais de 1,3 milhões de baciloscopias foram notificadas nos últimos dez anos no SUS. A mediana da incidência anual foi de 67 baciloscopias para hanseníase por 100.000 residentes, sendo a máxima observada em 2013 (82) e a mínima em 2022 (46). As incidências anuais nas macrorregiões Norte, Centro-oeste e Nordeste foram significativamente superiores à estimativa nacional, enquanto no Sul e Sudeste foram inferiores (p<0,05). A tendência temporal foi considerada decrescente para a estimativa nacional (p= 0,002), com variação percentualanual de -5,6% (IC95% = -3,8%; -8,2%). Entretanto, após desconsiderar os anos da pandemia de COVID-19 (2020-2022), a tendência tornou-se estacionária (p= 0,181). Além disso, a incidência durante o período pré-pandêmico foi significativamente maior quandocomparada ao terceiro ano após o advento da pandemia em todas as macrorregiões do Brasil (p<0,05). Conclusão:Foi possível concluir que o SUS realizou um número expressivo de baciloscopias para hanseníase nos últimos dez anos, mas existem disparidades macrorregionais no Brasil, bem como um impacto significativo da pandemia de COVID-19

Objective:To evaluate the annual number of skin smear microscopies for leprosy performed in the Unified Health System (SUS) in the last decade. Methods:An ecological, longitudinal, retrospective, and quantitative study was conducted using data from the Ambulatory Information System (SIA/SUS). The number of skin smear microscopies for leprosy per 100,000 residents was estimated for Brazil and its five macroregions, between 2013 and 2022, with a significance level (a) of 5%.Results:More than 1.3 million skin smear microscopies were reported in the last decade in the SUS. The median annual incidence was 67 skin smear microscopies for leprosy per 100,000 residents, with the maximum observed in 2013 (82) and the minimum in 2022 (46). Annual incidences in the North, Central-West, and Northeast macro-regions were significantly higher than the national estimate, whereas in the South and Southeast, they were lower (p <0.05). The temporal trend was considered decreasing for the national estimate (p = 0.002), with an annual percentage variation of -5.6% (95%CI = -3.8%; -8.2%). However, after disregarding the years of the COVID-19 pandemic (2020-2022), the trend became stationary (p = 0.181). Furthermore, the incidence during the pre-pandemic period was significantly higher compared with the third year after the advent of the pandemic in all macro-regions of Brazil (p<0.05).Conclusion:It was possible to conclude that the SUS performed a significant number of skin smear microscopies for leprosy in the last ten years, but there are macro-regional disparities in Brazil and a significant impact of the COVID-19 pandemic

DNA Barcode library of the endemic-rich avifauna of the oceanic islands of the Gulf of Guinea.

Background: The BioSTP: DNA Barcoding of endemic birds from oceanic islands of the Gulf of Guinea dataset contains records of 155 bird specimens belonging to 56 species in 23 families, representing over 80% of the diversity of the breeding landbird community. All specimens were collected on Príncipe, São Tomé and Annobón Islands between 2002 and 2021 and morphologically identified to species or subspecies level by qualified ornithologists. The dataset includes all endemic species and 3/4 of the extant endemic subspecies of the islands. This dataset is the second release by BioSTP and it greatly increases the knowledge on the DNA barcodes of Gulf of Guinea birds. All DNA extractions are deposited at Associação BIOPOLIS - CIBIO, Research Center in Biodiversity and Genetic Resources. New information: The dataset includes DNA barcodes for all 29 endemic bird species and for 11 of the 15 extant endemic bird subspecies from the oceanic islands of the Gulf of Guinea. This is the first major DNA barcode set of African birds. The three endemic subspecies of Crithagrarufobrunnea, an island endemic with three allopatric populations within the Archipelago, are also represented. Additionally, we obtained DNA barcodes for 16 of the 21 non-endemic landbirds and for one vagrant (Sylviacommunis). In total, forty-one taxa were new additions to the Barcode of Life Data System (BOLD), with another 11 corresponding to under-represented taxa in BOLD. Furthermore, the submitted sequences were found to cluster in 55 Barcode Index Numbers (BINs), 37 of which were new to BOLD. All specimens have their DNA barcodes publicly accessible through BOLD online database and GenBank.
