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.

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.

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.

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.

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.

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.

In vitro models of soft tissue damage by implant-associated frictional shear stresses.

Silicone elastomer medical implants are ubiquitous in medicine, particularly for breast augmentation. However, when these devices are placed within the body, disruption of the natural biological interfaces occurs, which significantly changes the native energy-dissipation mechanisms of living systems. These new interfaces can introduce non-physiological contact pressures and tribological conditions that provoke inflammation and soft tissue damage. Despite their significance, the biotribological properties of implant-tissue and implant-extracellular matrix (ECM) interfaces remain poorly understood. Here, we developed an in vitro model of soft tissue damage using a custom-built in situ biotribometer mounted onto a confocal microscope. Sections of commercially-available silicone breast implants with distinct and clinically relevant surface roughness (Ra = 0.2 ± 0.03 µm, 2.7 ± 0.6 µm, and 32 ± 7.0 µm) were mounted to spherically-capped hydrogel probes and slid against collagen-coated hydrogel surfaces as well as healthy breast epithelial (MCF10A) cell monolayers to model implant-ECM and implant-tissue interfaces. In contrast to the "smooth" silicone implants (Ra < 10 µm), we demonstrate that the "microtextured" silicone implant (10 < Ra < 50 µm) induced higher frictional shear stress (τ > 100 Pa), which led to greater collagen removal and cell rupture/delamination. Our studies may provide insights into post-implantation tribological interactions between silicone breast implants and soft tissues.

Family vulnerability scale: Evidence of content and internal structure validity.

INTRODUCTION: Territory view based on families' vulnerability strata allows identifying different health needs that can guide healthcare at primary care scope. Despite the availability of tools designed to measure family vulnerability, there is still a need for substantial validity evidence, which limits the use of these tools in a country showing multiple socioeconomic and cultural realities, such as Brazil. The primary objective of this study is to develop and gather evidence on the validity of the Family Vulnerability Scale for Brazil, commonly referred to as EVFAM-BR (in Portuguese). METHODS: Items were generated through exploratory qualitative study carried out by 123 health care professionals. The data collected supported the creation of 92 initial items, which were then evaluated by a panel of multi-regional and multi-disciplinary experts (n = 73) to calculate the Content Validity Ratio (CVR). This evaluation process resulted in a refined version of the scale, consisting of 38 items. Next, the scale was applied to 1,255 individuals to test the internal-structure validity by using the Exploratory Factor Analysis (EFA). Dimensionality was evaluated using Robust Parallel Analysis, and the model underwent cross-validation to determine the final version of EVFAM-BR. RESULTS: This final version consists of 14 items that are categorized into four dimensions, accounting for an explained variance of 79.02%. All indicators were within adequate and satisfactory limits, without any cross-loading or Heywood Case issues. Reliability indices also reached adequate levels (α = 0.71; ω = 0.70; glb = 0.83 and ORION ranging from 0.80 to 0.93, between domains). The instrument scores underwent a normalization process, revealing three distinct vulnerability strata: low (0 to 4), moderate (5 to 6), and high (7 to 14). CONCLUSION: The scale exhibited satisfactory validity evidence, demonstrating consistency, reliability, and robustness. It resulted in a concise instrument that effectively measures and distinguishes levels of family vulnerability within the primary care setting in Brazil.

HUMERAL SHAFT FRACTURE WITH AN INTACT WEDGE FRAGMENT: MIPO VS CONVENTIONAL PLATING.

Objectives: Evaluate bone healing time, consolidation, and the complication rate between the minimally invasive plate osteosynthesis and open reduction with plate osteosynthesis in humeral diaphyseal fractures with an intact wedge (AO 12B2). Methods: A retrospective study was carried out between 2016 and 2020. The medical records and radiographs of 18 patients were analyzed, and data were collected regarding the time of consolidation, age, sex, plate size, number of screws, complications such as iatrogenic injury damage to the radial nerve, material failure, and postoperative infection. Results: No statistically significant differences were observed in the variables of age, sex, plate size, and number of screws used or in the RUSHU index (Radiographic Union Score for Humeral fractures). There were no postoperative infections, material failure, or need for reoperation, nor cases of secondary radial nerve injury. After one year, all patients had a consolidation index analyzed by RUSHU >11. Conclusion: both techniques showed similar results, with a high consolidation rate and low rates of complications or iatrogenic damage to the radial nerve. Evidence level III; Retrospective comparative study .

Métodos: Foi realizado um estudo retrospectivo entre os anos de 2016 e 2020. Foram analisados os prontuários e radiografias de 18 pacientes e coletados dados referentes a: tempo de consolidação, idade, sexo, tamanho da placa, número de parafusos, presença de complicações como lesão iatrogênica do nervo radial, falha do material e infecção pós operatória. Resultados: Não foram observadas diferenças estatisticamente significativas nas variáveis de idade, sexo, tamanho da placa e número de parafusos utilizados, ou no índice de RUSHU (Radiographic Union Score for Humeral fractures). Não houve casos de infecção pós-operatória, falha do material ou necessidade de reoperação, nem casos de lesão secundária do nervo radial. Após 1 ano todos os pacientes tiveram índice de consolidação analisado pelo RUSHU >11. Conclusão: Ambas as técnicas se mostraram com resultados similares, com alta taxa de consolidação e baixas taxas de complicações ou lesão iatrogênica do nervo radial. Nível de evidência III; Estudo retrospectivo comparativo .

Emergence of cryptic species and clades of Meyerozyma guilliermondii species complex exhibiting limited in vitro susceptibility to antifungals in patients with candidemia.

Members of the Meyerozyma guilliermondii species complex are able to cause superficial and life-threatening systemic infections with low susceptibility to azoles and echinocandins. We tested 130 bloodstream M. guilliermondii complex isolates collected from eight Latin American medical centers over 18 years (period 1 = 2000-2008 and period 2 = 2009-2018) to investigate trends in species distribution and antifungal resistance. The isolates were identified by rDNA ITS region sequencing, and antifungal susceptibility tests were performed against fluconazole, voriconazole, anidulafungin, and amphotericin B using the CLSI microbroth method. M. guilliermondii sensu stricto (s.s.; n = 116) was the most prevalent species, followed by Meyerozyma caribbica (n = 12) and Meyerozyma carpophila (n = 2). Based on rDNA ITS identification, three clades within M. guilliermondii sensu stricto were characterized (clade 1 n = 94; clade 2 n = 19; and clade 3 n = 3). In the second period of study, we found a substantial increment in the isolation of M. caribbica (3.4% versus 13.8%; P = 0.06) and clade 2 M. guilliermondii s.s. exhibiting lower susceptibility to one or more triazoles. IMPORTANCE Yeast-invasive infections play a relevant role in human health, and there is a concern with the emergence of non-Candida pathogens causing disease worldwide. There is a lack of studies addressing the prevalence and antifungal susceptibility of different species within the M. guilliermondii complex that cause invasive infections. We evaluated 130 episodes of M. guilliermondii species complex candidemia documented in eight medical centers over 18 years. We detected the emergence of less common species within the Meyerozyma complex causing candidemia and described a new clade of M. guilliermondii with limited susceptibility to triazoles. These results support the relevance of continued global surveillance efforts to early detect, characterize, and report emergent fungal pathogens exhibiting limited susceptibility to antifungals.

Impacto da pandemia de COVID-19 na atuação do pediatra e do odontopediatra no Sistema Único de Saúde do Brasil / Impact of the COVID-19 pandemic on the performance of pediatricians and pediatric dentists in the Brazilian Unified Health System

Objetivo: Avaliar o impacto da pandemia de COVID-19 na produção ambulatorial de pediatras e odontopediatras no Sistema Único de Saúde do Brasil (SUS). Métodos: Foi realizado um estudo ecológico com abordagem analítica e quantitativa, usando dados de domínio público do Departamento de Informática do SUS. Foram recuperadas as quantidades mensais de profissionais que atuaram no SUS, a quantidade de procedimentos ambulatoriais de cada categoria profissional e a projeção de residentes de zero a 13 anos para normalizá-la. Os dados foram comparados entre os períodos pré-pandemia (2018-2020) e pandêmicos (2020-2022), com nível de significância de 5%. Resultados: Houve uma redução significativa na quantidade mensal de procedimentos ambulatoriais realizados no SUS pelos pediatras no primeiro e no segundo ano pandêmico de COVID-19 quando comparados ao período pré-pandemia (p < 0,001 e < 0,002, respectivamente). Tal redução representa uma redução mediana percentual de -57,1% (IC95% -51,3%; -71,7%) no primeiro e -22,3% (IC95% -0,55%; -31,5%) no segundo ano pandêmico. Em relação aos odontopediatras, redução significativa foi observada somente entre o período pré-pandemia e o primeiro ano pandêmico (p < 0,001), representando -82.0% (IC95% -73,4%; -93,6%). Além disso, observou-se uma correlação significativa, positiva e moderada entre a produtividade de ambas as categorias profissionais no SUS durante todo o período investigado (p < 0,001; ρ = 0,744). Conclusão: A pandemia de COVID-19 afetou negativamente a oferta de cuidado ambulatorial médico-odontológico especializado para crianças no SUS

Objective: To evaluate the impact of the COVID-19 pandemic on the outpatient production of pediatricians and pediatric dentists in the Brazilian Unified Health System (SUS). Methods: An ecological study was conducted with an analytical and quantitative approach using public domain data from the SUS Department of Informatics. The monthly number of professionals who worked in the SUS, the number of outpatient procedures in each category, and the projection of residents from zero to thirteen years old to normalize it were retrieved. Data were compared by pre-pandemic (2018-2020) and pandemic (2020-2022) periods with a significance level of 5%. Results: There was a significant reduction in the monthly number of outpatient procedures performed in the SUS by pediatricians in the first and second pandemic years of COVID-19 compared to the pre-pandemic period (p < 0.001 and 0.002, respectively). This reduction represents a median percentage reduction of -57.1% (95%CI -51.3%, -71.7%) in the first and -22.3% (95%CI -0.55%, -31.5%) in the second pandemic year. Regarding pediatric dentists, a significant reduction was observed only between the pre-pandemic period and the first pandemic year (p < 0.001), representing -82.0% (95%CI -73.4%, -93.6%). Moreover, a significant positive and moderate correlation was observed between the productivity of both professional categories in the SUS throughout the investigated period (p < 0.001, ρ= 0.744). Conclusion: The COVID-19 pandemic negatively affected the provision of specialized medical and dental outpatient care for children in the SUS

In-Loco Optical Spectroscopy through a Multiple Digital Lock-In on a Linear Charge-Coupled Device (CCD) Array.

Accurate and reliable measurements of optical properties are crucial for a wide range of industrial and commercial applications. However, external illumination fluctuations can often make these measurements challenging to obtain. This work proposes a new technique based on digital lock-in processing that enables the use of CCD spectrometers in optical spectroscopy applications, even in uncontrolled lighting conditions. This approach leverages digital lock-in processing, performed on each pixel of the spectrometer's CCD simultaneously, to mitigate the impact of external optical interferences. The effectiveness of this method is demonstrated by testing and recovering the spectrum of a yellow LED subjected to other light sources in outdoor conditions, corresponding to a Signal-to-Noise Ratio of -70.45 dB. Additionally, it was possible to demonstrate the method's applicability for the spectroscopic analysis of gold nanoparticles in outdoor conditions. These results suggest that the proposed technique can be helpful for a wide range of optical measurement techniques, even in challenging lighting conditions.

Design and methodology of the SARCopenia trajectories and associations with adverse clinical outcomes in patients on HemoDialysis: the SARC-HD study.

BACKGROUND: Sarcopenia has been associated with adverse outcomes in patients with chronic kidney disease (CKD), particularly in those undergoing hemodialysis (HD). However, the trajectories across sarcopenia stages, their determinants, and associations with adverse clinical outcomes have yet to be comprehensively examined. METHODS: The SARC-HD is a multicenter, observational prospective cohort study designed to comprehensively investigate sarcopenia in patients on HD. Eligibility criteria include adult patients undergoing HD for ≥ 3 months. The primary objective is to investigate the trajectories of sarcopenia stages and their potential determinants. Secondary objectives include evaluating the association between sarcopenia and adverse clinical outcomes (i.e., falls, hospitalization, and mortality). Sarcopenia risk will be assessed by the SARC-F and SARC-CalF questionnaire. Sarcopenia traits (i.e., low muscle strength, low muscle mass, and low physical performance) will be defined according to the revised European Working Group on Sarcopenia in Older People and will be assessed at baseline and after 12 follow-up months. Patients will be followed-up at 3 monthly intervals for adverse clinical outcomes during 24 months. DISCUSSION: Collectively, we expect to provide relevant clinical findings for healthcare professionals from nephrology on the association between sarcopenia screening tools (i.e., SARC-F and SARC-CalF) with objective sarcopenia measurements, as well as to investigate predictors of trajectories across sarcopenia stages, and the impact of sarcopenia on adverse clinical outcomes. Hence, our ambition is that the data acquired from SARC-HD study will provide novel and valuable evidence to support an adequate screening and management of sarcopenia in patients on HD.

Pioneer of Cardiothoracic Surgery - Joaquim Cavalcanti.

Joaquim de Souza Cavalcanti was a pioneer among us - the Brazilian State of Pernambuco and North-Northeast region - in cardiac surgery in its initial phase (Blalock-Taussig surgery and mitral valvulotomy), in thoracic surgery (pneumectomy, lung lobectomy and segmentectomy, lung decortication, and mediastinal tumor resection), and in numerous techniques and operative tactics in general surgery.

Long-Term Lifestyle Habits and Quality of Life after Roux-in-Y Gastric Bypass in Brazilian Public versus Private Healthcare Systems: Beyond Weight Loss.

Lifestyle and health-related quality of life (HRQoL) are good markers of surgical obesity treatment. This study aimed to investigate the lifestyle and HRQoL of patients at least five years after Roux-en-Y gastric bypass in public (SUS) and private (PVT) Brazilian healthcare systems. In this cross-sectional study, weight loss (WL), % of excess WL (%EWL), diet quality, physical activity, alcohol consumption, and HRQoL were evaluated. Analysis of covariance, binary and multinomial logistic regression, adjusted for confounders, were performed. The SUS group had more vulnerable socioeconomic statuses than the PVT group. Total %WL and % EWL were 24.64 ± 0.99% and 60.46 ± 2.41%, respectively, without difference between groups. In the Pain/Discomfort and Anxiety/Depression domains of HRQoL, more than 50% reported moderate problems without differences between groups. Processed food ingestion was higher in the PVT (132.10 ± 60.15 g/1000 kcal) than in the SUS (103.43 ± 41.72 g/1000 kcal), however, without statistical significance (p = 0.093). The PVT group showed lower physical activity (OR: 0.23; 95%CI: 0.87-0.63; p = 0.004) and a higher risk of alcohol-related problems (OR: 3.23; 95%CI; 1.03-10.10; p = 0.044) compared to SUS group. Participants generally achieved satisfactory WL, regardless of healthcare systems. However, PVT participants had unfavorable lifestyle characteristics, highlighting the need for studies investigating environmental issues post-bariatric surgery.
